    Performing two DIEP flaps in a working day: an achievable and reproducible practice2010In: Journal of Plastic, Reconstructive and Aesthetic Surgery, ISSN 1748-6815, Vol. 63, no 4, p. 648-654Article in journal (Refereed)
    Abstract [en]

    Background: While the deep inferior epigastric artery perforator (DIEP) flap is a reliable technique for autologous breast reconstruction, the meticulous dissection of perforators may require lengthy operative times. In our unit, we have performed 600 free flaps for breast reconstruction over 8 years and have reduced operative times with a combination of preoperative computed tomographic angiography (CTA), various anastomotic techniques and the Cook-Swartz implantable Doppler probe for perfusion monitoring. We sought to assess the feasibility of performing two DIEP flaps within the working hours of a single day. Methods: A review of 101 consecutive patients undergoing DIEP flap breast reconstruction in a 12-month period was performed, comparing one DIEP flap per day (n=43) to two DIEP flaps per day (n=58). Complications, outcomes and techniques used were critically analysed. For cases of two DIEP flaps per day, a comparison was made between the use of two separate operating theatres (n=44) and a single consecutive theatre (n=14). Results: Complications did not increase when two DIEP flaps were performed in a single working day. The use of vascular closure staple (VCS) sutures and ring couplers resulted in statistically significant reductions in anastomotic times. The use of two separate theatres for performing two DIEP flaps resulted in a reduction of 59 min in operative time per case (p=0.004). Conclusion: Two DIEP flaps can be safely and routinely performed within the hours of a single working day. By minimising operative times, these techniques can improve productivity and substantially decrease surgeon fatigue.

    A Clinical Review of 9 Years of Free Perforator Flap Breast Reconstructions: An Analysis of 675 Flaps and the Influence of New Techniques on Clinical Practice2011In: Journal of reconstructive microsurgery, ISSN 0743-684X, E-ISSN 1098-8947, Vol. 27, no 2, p. 91-98Article, review/survey (Refereed)
    Abstract [en]

    The aim of this study is to review our 9-year experience with deep inferior epigastric perforator (DIEP) breast reconstructions to help others more easily overcome the pitfalls we experienced. A chart review was conducted for all 543 patients who had 622 DIEP breast reconstructions in our clinic between January 2000 and January 2009. In this time, there were an additional 28 superior gluteal artery perforator and 25 superficial inferior epigastric artery reconstructions, bringing the total free flap reconstructions to 675. In the early years, the success rate was 90.7%, the average operative time was 7 hours and 18 minutes, and the complication rate was 33.3%; these have improved to 98.2%, 4 hours and 8 minutes, and 19.3%, respectively. We describe our selection criteria, preoperative vascular mapping, surgical techniques, and postoperative monitoring as they relate to these improvements in outcome, operative time, and complications. The DIEP flap is a safe and reliable option in breast reconstructions. By acquiring experience with the flap and introducing new and improving existing techniques we have improved the ease of the procedure and the success rate and have shortened the operative time.

    A case report of a complete degloving injury of the penile skin2016In: International journal of surgery case reports, ISSN 2210-2612, E-ISSN 2210-2612, Vol. 29, p. 1-3Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Male genital degloving injuries are unusual and rarely caused by animal bite. Usually patients attend health care immediately if bitten in the genital area. Prophylactic antibiotics is routinely used (Gomes et al., 2000). A penile degloving usually begins just proximal of the coronal line and progress down to the base of the shaft. Deep erectile tissue and the spermatic cord are seldom damaged and the endogenous skin of glans usually survives (Brown and Fryer, 1957; Morey et al., 2004; Finical and Arnold, 1999).

    PRESENTATION OF CASE: A heavily smoking man with a previous history of bladder cancer presented himself to the emergency department 24h after a dog bite degloved his penis. The avulsed skin was necrotic and subsequently excised. Antibiotic treatment was started. A bacterial swab was found positive for canine oral flora. The skin defect was closed using a 1:1 meshed split thickness skin graft from the inner thigh. Smoking cessation was encouraged. At the three month follow up the patient expressed satisfaction with both cosmetic and functional result and was now non-smoking.

    DISCUSSION: Several approaches to reconstruct penile skin exist. Split thickness skin graft has been lifted as a preferable alternative (Brown and Fryer, 1957; Finical and Arnold, 1999; Paraskevas et al., 2003) [5]. In this case, the avulsed skin was necrotic and could not be used. A 1:1 meshed split-thickness graft was chosen with excellent results.

    CONCLUSION: 1:1mesh of the graft can be recommended for easy attachment with a good functional and esthetical result. The potential risk of losing intimacy appearance or having to go through repeated procedures in the genital area motivated smoking cessation for this patient.

    Structure and locomotion of adult in vitro regenerated spiral ganglion growth cones: a study using video microscopy and SEM2006In: Hearing Research, ISSN 0378-5955, E-ISSN 1878-5891, Vol. 215, no 1-2, p. 97-107Article in journal (Refereed)
    Abstract [en]

    Neuronal development and neurite regeneration depends on the locomotion and navigation of nerve growth cones (GCs). There are few detailed descriptions of the GC function and structure in the adult auditory system. In this study, GCs of adult dissociated and cultured spiral ganglion (SG) neurons were analyzed in vitro utilizing combined high resolution scanning electron microscopy (SEM) and time lapse video microscopy (TLVM). Axon kinesis was assessed on planar substratum with growth factors BDNF, NT-3 and GDNF. At the nano-scale level, lamellipodial abdomen of the expanding GC was found to be decorated with short surface specializations, which at TLVM were considered to be related to their crawling capacity. Filopodia were devoid of these surface structures, supporting its generally described sensory role. Microspikes appearing on lamellipodia and axons, showed circular adhesions, which at TLVM were found to provide anchorage of the navigating and turning axon. Neurons and GCs expressed the DCC-receptor for the guidance molecule netrin-1. Asymmetric ligand-based stimulation initiated turning responses suggest that this attractant cue influences steering of GC in adult regenerating auditory neurites. Hopefully, these findings may be used for ensuing tentative navigation of spiral ganglion neurons to induce regenerative processes in the human ear.

    Social competence and behaviour problems in burned children2003In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 29, no 1, p. 25-30Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to collect follow-up data on social competence and behavioural problems in a sample of Swedish burned children and to compare the results with normative data from a reference group of children comparable in age, socio-economic status and gender. Parents of 44 children (55% response rate) aged 7-12 years were asked to complete a questionnaire booklet including the Children's Behaviour Questionnaire (CBQ) and the Social Competence Inventory (SCI). Data from the children's teachers were also collected for 20 children using the same booklet. In addition, data on TBSA, localisation of injury, and other background factors were collected. Results showed that the burned children were rated by their parents as showing lesser degrees of social initiative and more externalising problems and concentration problems compared with the control group. Teachers rated the burn injured children as having less prosocial orientation, more externalising problems, and more concentration problems. No clear effects were found for gender and characteristics of the burn injury. Results on the Social Competence Inventory were associated with scores on the Children's Behaviour Questionnaire.The findings are consistent with previous research in that the differences found were relatively small. However, they do call for attention to the possible adverse effects of growing up with a burn injury, but also to the possible pre-morbid characteristics that may be related to the injury.

    Long-term influence of infant periosteoplasty on facial growth and occlusion in patients with bilateral cleft lip and palate2012In: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery, ISSN 2000-656X, E-ISSN 2000-6764, Vol. 46, no 3-4, p. 229-234Article in journal (Refereed)
    Abstract [en]

    This retrospective, long-term study evaluated the influence of two different treatment protocols, one including infant periosteoplasty, on facial growth and occlusion in patients with complete bilateral cleft lip and palate (BCLP). Thirty-five patients with records of 5-, 8- and I 6-19-year-olds were included. Sixteen of these received infant periosteoplasty (BCLP-pp) to the cleft alveolus in conjunction with lip repair and a one-stage closure of the palate. The remaining 19 patients with a two-stage closure of the palate did not have an infant periosteoplasty (BCLP-np). The bone formation induced by periosteoplasty in the BCLP-np group was insufficient and both groups had secondary bone grafting to the alveolar clefts before the eruption of the lateral incisor or the canine. Facial growth was evaluated with cephalometry at the recorded ages and dental arch relationships with the Huddart and Bodenham crossbite scores at the age of 16-19 years. Until 19 years a significant retrusion of the maxillary position (SNA) was observed in both groups. At 16-19 years of age there was no significant difference of maxillary protrusion (SNA), intermaxillary position (ANB), maxillary length (ss-pm) or vertical skeletal relationships (ML/NSL, MI/NL) between the two groups. However, a significant difference of the crossbite scores was found. The BCLP-pp group did not show more facial growth problems but more malocclusion and the insufficient bone formation of the alveolar clefts after infant periosteoplasty required a secondary bone grafting.

    Congenital granular cell epulis: a case report2015In: Oral and Maxillofacial Surgery Cases, ISSN 2214-5419, Vol. 1, no 1, p. 8-11Article in journal (Refereed)
    Abstract [en]

    Congenital granular cell epulis (CGCE) is an uncommon benign lesion found in newborns. It has predominance for females with an 8:1 ratio in relation to males and is exclusively encountered in the oral cavity. The most affected oral site is located around the canine/incisor region of the maxillary alveolar ridge, where the lesion arises from the soft tissue as a solitary pedunculated mass. CGCE's histogenesis remains obscure and controversial. We present a rare case of 2 separate CGCE lesions adjacent to each other measuring 23 × 18 × 10 and 15 × 10 mm, positioned facially on the right maxillary alveolar process. The patient, a 2-day-old female newborn, did not experience any serious difficulty regarding breathing or deglutition. Complete surgical excision was the treatment of choice in this case, and the procedure was performed under both general and local anesthesia. Histologic and immunohistochemical analysis confirmed the diagnosis of CGCE. The patient showed satisfactory postoperative healing and excellent health at both the 10-day recall appointment and the 6-month follow-up.

    Nerve Transfers for Facial Transplantation: a cadaveric study for motor and sensory restoration2013In: Plastic and reconstructive surgery (1963), ISSN 0032-1052, E-ISSN 1529-4242, Vol. 131, no 6, p. 1231-1240Article in journal (Refereed)
    Abstract [en]

    BACKGROUND

    Restoration of facial animation and sensation are highly important for the outcome after facial allotransplantation. The identification of healthy nerves for neurotization, through recipient to donor nerve coaptation, is of particular importance for successful nerve regeneration within the allograft. However, due to the severity of the initial injury and resultant scar formation, a lack of healthy nerve stumps in the recipient is a commonly encountered problem. In this study, we evaluate the technical feasibility of performing nerve transfers in facial transplantation for both sensory and motor neurotization.

    METHODS

    Fifteen fresh cadaver heads were used in this study. The study was divided in two parts. First, the technical feasibility of nerve transfer from the cervical plexus (CP) to the mental nerve (MN) and the masseter nerve (MaN) to the buccal branches of the facial nerve (BBFN) was assessed. Next, we performed nerve transfers in simulated face transplants to describe the surgical technique focusing on sensory restoration of the midface and upper lip by neurotization of the infraorbital nerve (ION), sensory restoration of the lower lip by neurotization of the MN, and smile reanimation by neurotization of the BBFN.

    RESULTS

    In all specimens coaptation of at least one of branches of the CP to the mental nerve was possible as well as between the masseter nerve to the buccal branch of the facial nerve. In simulated face transplant procedures nerve transfers of the supraorbital nerve (SON) to the infraorbital nerve (ION), cervical plexus branches to the mental nerve, and masseter nerve to facial nerve are all technically possible.

    CONCLUSION

    Nerve transfers are a technically feasible option that could theoretically be used in face transplantation either as a primary nerve reconstruction when there are no available healthy nerves, or as a secondary procedure for enhancement of functional outcomes. The supraorbital nerve, branches of the cervical plexus and the masseter nerve are nerves usually located out of the zone of injury and can be selected as neurotizers for the infraorbital nerve, mental nerve and buccal branch of the facial nerve respectively.

    A Reliable and Aesthetic Technique for Cephalic Vein Harvest in DIEP Flap Surgery2009In: Journal of reconstructive microsurgery, ISSN 0743-684X, E-ISSN 1098-8947, Vol. 25, no 5, p. 319-321Article in journal (Refereed)
    Abstract [en]

    The need for a secondary source of venous drainage in deep inferior epigastric artery perforator flaps is common, with the cephalic vein Commonly utilized as an alternative venous recipient vessel. In using the cephalic vein, previous studies have described the deltopectoral groove or the infraclavicular fossa as the site for harvest. We describe the use of an anterior axillary skin crease, which can improve aesthetic outcome, reduce the time needed for harvest, enable a greater length of vein to be transposed, and minimize surgical insult to the upper breast/chest wall. An anterior axillary-line skin fold can be used as the site for cephalic vein harvest, and using the methodology described, the technique can be fast and highly reliable and result in a final scar that is barely visible.

    Late complications of high-voltage electrical injury might involve multiple systems and be related to current path2016In: Annals of Burns and Fire Disasters, ISSN 1121-1539, E-ISSN 1592-9558, Vol. 29, no 3, p. 192-194Article in journal (Refereed)
    Abstract [en]

    SUMMARY

    Delayed complications of electrical burns are mostly unexpected, and the link between the injury and the symptoms oftengoes unrecognized. A possible relation between source-ground sites and late clinical manifestations was recently emphasized. We report aunique case of combined intestinal-spinal delayed complications following a high-voltage electrical injury, a possible explanation being agreater current flow through the right hemisoma. The potential for late complications is an additional feature that physicians must considerin managing electrical injuries. Manifestations are variable and presentation is confounding, but current flow path can constitute a precioussource of information to predict complications in the late phase of management.

    Global DNA Methylation Analysis Identifies Two Discrete clusters of Pheochromocytoma with Distinct Genomic and Genetic Alterations2017In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 7, article id 44943Article in journal (Refereed)
    Abstract [en]

    Pheochromocytomas and paragangliomas (PPGLs) are rare and frequently heritable neural-crest derived tumours arising from the adrenal medulla or extra-adrenal chromaffin cells respectively. The majority of PPGL tumours are benign and do not recur with distant metastases. However, a sizeable fraction of these tumours secrete vasoactive catecholamines into the circulation causing a variety of symptoms including hypertension, palpitations and diaphoresis. The genetic landscape of PPGL has been well characterized and more than a dozen genes have been described as recurrently mutated. Recent studies of DNA-methylation have revealed distinct clusters of PPGL that share DNA methylation patterns and driver mutations, as well as identified potential biomarkers for malignancy. However, these findings have not been adequately validated in independent cohorts. In this study we use an array-based genome-wide approach to study the methylome of 39 PPGL and 4 normal adrenal medullae. We identified two distinct clusters of tumours characterized by different methylation patterns and different driver mutations. Moreover, we identify genes that are differentially methylated between tumour subcategories, and between tumours and normal tissue.

    The Course of Pain in Bell's Palsy: Treatment With Prednisolone and Valacyclovir2009In: Otology and Neurotology, ISSN 1531-7129, E-ISSN 1537-4505, Vol. 30, no 6, p. 842-846Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate the effect of prednisolone and valacyclovir on ipsilateral pain around the ear and in the face or neck in Bell's palsy. The incidence and intensity of pain during the first 2 months of palsy and its prognostic value were also assessed. Study Design: Prospective, randomized, double-blind, placebo-controlled, multicenter trial. Setting: Sixteen tertiary referral centers in Sweden and 1 in Finland. Patients: Data are part of the Scandinavian Bell's palsy study; 829 patients aged 18 to 75 years with onset of palsy within 72 hours were included. Follow-up time was 12 months. Intervention: Patients were assigned to 1 of 4 treatment arms in a factorial fashion: placebo plus placebo; prednisolone 60 mg daily for 5 days, then tapering for 5 days, plus placebo; valacyclovir 1,000 mg 3 times daily for 7 days plus placebo; or prednisolone plus valacyclovir. Main Outcome Measures: Pain was registered on a visual analog scale within 72 hours, at Days 11 to 17, 1 month, and 2 months. Facial function was assessed with the Sunnybrook and House-Brackmann systems. Results: Prednisolone and/or valacyclovir did not significantly affect the incidence or intensity of pain during the first 2 months. Pain was registered in 542 (65%) of 829 patients. At 2 months, 53 (8%) of 637 patients still reported pain. Subjects with pain at Days 11 to 17 had lower facial recovery rates at 12 months than those with no pain (p < 0.0001). Conclusion: Prednisolone and/or valacyclovir did not affect the incidence or intensity of ipsilateral pain in Bell's palsy. The incidence of pain was similar during the first 2 weeks and then decreased. Presence of pain at Days 11 to 17 indicated a worse prognosis for facial recovery.

    "Between Men": A psychosocial rehabilitation programme for men with prostate cancer2007In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 46, no 1, p. 83-89Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to evaluate the effect of psychosocial rehabilitation on newly diagnosed prostate cancer patients. The “Between Men” programme consisted of seven weekly sessions of physical training (Phys) alone, information (Info) alone or physical training plus information (PhysInfo). After diagnoses, patients (n =211) were consecutively included, stratified and randomised to one of four groups: Phys, Info, PhysInfo or standard care control (C). A nurse specialised in urology, an urologist and a physiotherapist performed the interventions. Patients were followed up during one year with mailed standardised questionnaires. It could not be assumed that the “Between Men” programme had any effect on patients’ anxiety and depression (HADS). Health-related quality of life (HRQOL) was associated with stage of disease but not with psychosocial intervention. Thus, Physical Function (PF), Role Function (RF) and Fatigue (FA) were inferior among patients with, than without, metastases of prostate cancer both at baseline and at the 12-month follow-up. This randomized study did not demonstrate any significant effect of psychosocial rehabilitation among prostate cancer patients. Considering the low rate (1/2), of included/eligible patients a less complicated design (intervention versus control) would have been preferred in order to increase power.

    Glucocorticoid receptor expression and binding capacity in patients with burn injury2016In: Acta Anaesthesiologica Scandinavica, ISSN 0001-5172, E-ISSN 1399-6576, Vol. 60, no 2, p. 213-221Article in journal (Refereed)
    Abstract [en]

    Background

    Burn injuries are associated with strong inflammation and risk of secondary sepsis which both may affect the function of the glucocorticoid receptor (GR). The aim of this study was to determine GR expression and binding capacity in leucocytes from patients admitted to a tertiary burn center.

    Methods

    Blood was sampled from 13 patients on admission and days 7, 14 and 21, and once from 16 healthy subjects. Patients were grouped according to the extent of burn and to any sepsis on day 7. Expression and binding capacity of GR were determined as arbitrary units using flow cytometry.

    Results

    GR expression and binding capacity were increased compared to healthy subjects in most circulating leucocyte subsets on admission irrespective of burn size. Patients with sepsis on day 7 displayed increased GR expression in T lymphocytes (51.8%, < 0.01) compared to admission. There was a negative correlation between GR binding capacity in neutrophils and burn size after 14 days (< 0.05).

    Conclusions

    GR expression and binding capacity are increased in most types of circulating leucocytes of severely burned patients on their admission to specialized burn care. If sepsis is present after 1 week, it is associated with higher GR expression in T lymphocytes and NK cells.

    Excess cause-specific mortality in out-patients with personality disorder2015In: British Journal of Psychiatry Open, ISSN 2056-4724, Vol. 1, no 1, p. 54-55Article in journal (Refereed)
    Abstract [en]

    Personality disorders (PDs) are associated with increased overall mortality. In patients hospitalised with a principal diagnosis of PD, this is observed for all clusters and for natural as well as unnatural causes of death. Data from Swedish nationwide registers were used to assess whether this was also true for the majority of patients diagnosed with PDs not severe enough to lead to hospitalisation. There was an increased mortality in all clusters, and for natural as well as unnatural death, also in patients treated as out-patients only, although not to the same extent as in those hospitalised.

    Suicide risk and suicide method in patients with personality disorders2016In: Journal of Psychiatric Research, ISSN 0022-3956, E-ISSN 1879-1379, Vol. 83, p. 29-36Article in journal (Refereed)
    Abstract [en]

    Objective: The influence of psychopathology on suicide method has revealed different distributions among different psychiatric disorders. However, evidence is still scarce. We hypothesized that having a diagnosis of personality disorder (PD) affect the suicide method, and that different PD clusters would influence the suicide method in different ways. In addition, we hypothesized that the presence of psychiatric and somatic co-morbidity also affects the suicide method. Method: We examined 25,217 individuals aged 15-64 who had been hospitalized in Sweden with a main diagnosis of PD the years 1987-2013 (N = 25,217). The patients were followed from the date of first discharge until death or until the end of the follow-up period, i.e. December 31, 2013, for a total of 323,508.8 person-years, with a mean follow up time of 11.7 years. The SMR, i.e. the ratio between the observed number of suicides and the expected number of suicides, was used as a measure of risk. Results: Overall PD, different PD-clusters, and comorbidity influenced the suicide method. Hanging evidenced highest SMR in female PD patients (SMR 34.2 (95% CI: 29.3-39.8)), as compared to non-PD patients and jumping among male PD patients (SMR 24.8 (95% CI: 18.3-33.6)), as compared to non PD-patients. Furthermore, the elevated suicide risk was related to both psychiatric and somatic comorbidity. Conclusion: The increased suicide risk was unevenly distributed with respect to suicide method and type of PD. However, these differences were only moderate and greatly overshadowed by the overall excess suicide risk in having PD. Any attempt from society to decrease the suicide rate in persons with PD must take these characteristics into account.

    Excess cause-specific mortality in in-patient-treated individuals with personality disorder: 25-year nationwide population-based study.2015In: British Journal of Psychiatry, ISSN 0007-1250, E-ISSN 1472-1465, Vol. 207, no 4, p. 339-345Article in journal (Refereed)
    Abstract [en]

    BackgroundAlthough personality disorders are associated with increased overall mortality, less is known about cause of death and personality type.AimsTo determine causes of mortality in ICD personality disorders.MethodBased on data from Swedish nationwide registers, individuals admitted to hospital with a primary diagnosis of personality disorder between 1987 and 2011 were followed with respect to mortality until 31 December 2011. Standardised mortality ratios (SMRs) with 95% confidence intervals and underlying causes of death were calculated.ResultsAll-cause SMRs were increased, overall and in all clusters, for natural as well as unnatural causes of death. The overall SMR was 6.1 in women and 5.0 in men, as high as previously reported for anorexia nervosa, with higher rates in cluster B and mixed/other personality disorders. The SMR for suicide was 34.5 in women and 16.0 in men for cluster B disorders. Somatic and psychiatric comorbidity increased SMRs.ConclusionsThe SMR was substantially increased for all personality disorder clusters. Thus, there was an increased premature mortality risk for all personality disorders, irrespective of category.

    SoftCut: A Virtual Planning Tool for Soft Tissue Resection on CT Images2018In: Medical Image Understanding and Analysis / [ed] Mark Nixon, Sasan Mahmoodi, and Reyer Zwiggelaar, Cham: Springer, 2018, Vol. 894, p. 299-310Conference paper (Refereed)
    Abstract [en]

    With the increasing use of three-dimensional (3D) models and Computer Aided Design (CAD) in the medical domain, virtual surgical planning is now frequently used. Most of the current solutions focus on bone surgical operations. However, for head and neck oncologic resection, soft tissue ablation and reconstruction are common operations. In this paper, we propose a method to provide a fast and efficient estimation of shape and dimensions of soft tissue resections. Our approach takes advantage of a simple sketch-based interface which allows the user to paint the contour of the resection on a patient specific 3D model reconstructed from a computed tomography (CT) scan. The volume is then virtually cut and carved following this pattern. From the outline of the resection defined on the skin surface as a closed curve, we can identify which areas of the skin are inside or outside this shape. We then use distance transforms to identify the soft tissue voxels which are closer from the inside of this shape. Thus, we can propagate the shape of the resection inside the soft tissue layers of the volume. We demonstrate the usefulness of the method on patient specific CT data.

    Telemedicine: a complement to traditional referrals in oral medicine2012In: Telemedicine journal and e-health, ISSN 1530-5627, E-ISSN 1556-3669, Vol. 18, no 7, p. 549-553Article in journal (Refereed)
    Abstract [en]

    Introduction:

    Introducing telemedicine into clinical practice has not been without difficulties. Within the framework of the European Union project "Health Optimum," telemedicine consultations with specialists at the Department of Oral & Maxillofacial Surgery at Uppsala University Hospital (Uppsala, Sweden) have been offered to dentists in the public dental health service. The aim is to streamline the consultation process, improve/develop the skills of the participating dentists and dental hygienists, and save time and money for patients, healthcare authorities, and society.

    Subjects and Methods:

    Patient records are collected in a database for demonstration and discussion, and the system is also available for referrals. Both medical and dental photographs and x-rays are digitized in the same system. These can be viewed during telemedicine rounds and by the consultants at the hospital prior to a consultation. Secure, interactive conferencing software is used, which provides a quick, easy, and effective way to share video and data over the Internet. Both parties can demonstrate different parts of an image using a pointer or a drawing system. Conference phones are presently used for verbal communication.

    Results:

    Ten patients were discussed during telemedicine rounds (3 males and 7 females), all of whom would normally have been referred to a specialist. As a result of the telemedicine round, 2 were referred to a specialist, whereas diagnoses were made for the other 8, and treatment was suggested. The dental health clinic could thus provide treatment without the need for referral to a consultant.

    Conclusions:

    The telemedicine system described here allows patient care to be provided rapidly and more economically. Future plans include "live" rounds using a videocamera, providing the possibility to relay real-time information about the intraoral situation. A camera is being developed and should preferably be permanently installed chair side.

    Abstract [sv]

    En genomgång av brandskadade i Sverige 2010. Den epidemiologiska kunskapen om, och omfattningen av, personskador orsakade av eld och rök (såväl lindriga som svåra och dödliga) är otillräcklig. Målet med denna studie, som genomförts av Institutionen för Kirurgiska vetenskaper vid Uppsala universitet i samverkan med MSB, har varit att sammanställa tillgänglig data över skador som kan kopplas till en brand under 2010 och lyfta fram särskilt utsatta grupper. Detta för att skapa en epidemiologisk kunskapsbas som kan ligga till grund för preventionsarbete och vidare forskning.

    Effects of Neurotrophic Factors on Growth and Glial Cell Alignment of Cultured Adult Spiral Ganglion Cells2009In: Audiology & neuro-otology, ISSN 1420-3030, E-ISSN 1421-9700, Vol. 15, no 3, p. 175-186Article in journal (Refereed)
    Abstract [en]

    Adult spiral ganglion cells were cultured in chorus to assess the influence of the neurotrophins brain-derived neurotrophic factor, neurotrophin 3 and glial cell line-derived neurotrophic factor (GDNF) on neurite growth and Schwann cell alignment. Over 1500 measurements were collected using each factor at 10 ng/ml and all three in combination. Evaluation was made with GDNF at concentrations of up to 100 ng/ml. Neurite dimensions were assessed at days 5, 7, 9 and 11 using a computer-based program (Axon Analyzer). GDNF had a strong effect on spiral ganglion cell growth almost attaining the level of all three factors in combination. GDNF increased glial cell alignment and nerve bundle formation. Results show the potential of GDNF to maintain and possibly restore auditory nerve integrity.

    Synkinesis in Bell's palsy in a randomised controlled trial2017In: Clinical Otolaryngology, ISSN 1749-4478, E-ISSN 1365-2273, Vol. 42, no 3, p. 673-680Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To study the development of synkinesis in Bell's palsy. Frequency, severity, gender aspects and predictors were analysed.

    DESIGN: Data from the randomised controlled Scandinavian Bell's palsy trial including 829 patients.

    MAIN OUTCOME MEASURES: Frequency and severity of synkinesis at 12 months were the main outcome measures. Mean Sunnybrook synkinesis scores, voluntary movement scores and composite scores between 6 and 12 months were compared.

    RESULTS: In 743 patients with a 12-month follow-up, synkinesis frequency was 21.3%. There was no gender difference. Synkinesis was moderate to severe in 6.6% of patients. Those with synkinesis at 6 months had a synkinesis score of 4.1 (±2.8 sd), which increased to 4.7 (±3.2) (P = 0.047) at 12 months (n = 93). Sunnybrook composite score at 1 month was the best predictor for synkinesis development with receiver operating characteristics and area under the curve (AUC) 0.87. Risk for synkinesis increased with a lower Sunnybrook composite score. Furthermore, at 1 month, symmetry of voluntary movement had higher predictive value for synkinesis than resting symmetry with AUC 0.87 and 0.77, respectively. Gentle eye closure and open-mouth smile were the only independent significant predictive items (AUC 0.86).

    CONCLUSIONS: Moderate-to-severe synkinesis was present in 6.6% of patients. The mean synkinesis score increased between 6 and 12 months, and outcome should therefore be evaluated after at least 12 months. Sunnybrook composite score and symmetry of voluntary movement at 1 month were good predictors for synkinesis.

    Prediction of psychological symptoms in family members of patients with burns 1 year after injury2013In: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 69, no 2, p. 384-393Article in journal (Refereed)
    Abstract [en]

    Aim

    To report a study of predictors of psychological symptoms in family members of patients with burns.

    Background

    Family members are important as a source of social support for patients undergoing prolonged rehabilitation. Little is known about psychological symptoms of family members of patients with burns, especially in the long term.

    Design

    The design of the study was prospective and longitudinal.

    Methods

    Forty-four family members of adult patients treated in a burn centre between 2000-2007 completed questionnaires during care and at 3, 6, and 12 months after injury. Psychological symptoms were assessed with the Hospital Anxiety and Depression Scale. Predictors for anxiety and depression were explored in regression analyses.

    Results

    The mean scores indicated normal to mild symptoms in general. Moderate and severe symptom levels during care and at 12 months were demonstrated on the anxiety subscale by 15/44 and 5/39, respectively, and on the depression subscale by 5/44 and 0/39 of the family members, respectively. In the final regression models, the primary predictor was psychological symptoms at the previous assessment. Other predictors were previous life events, age, and the coping strategy avoidance.

    Conclusion

    Family members of patients with burns demonstrate normal to mild levels of psychological symptoms that decrease over time. One-third show moderate to severe anxiety symptoms during care and may benefit from counselling. Previous symptoms predict later symptoms, indicating that screening with a validated instrument is useful. The results provide guidance for nurses in assessing and planning adequate interventions for family members.

    Health-related quality of life in family members of patients with burns2014In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 35, no 3, p. 243-250Article in journal (Refereed)
    Abstract [en]

    A severe burn not only affects the patients, but may also have a great impact on the lives of family members. It is known that family members of patients with burns experience psychological distress, but health-related quality of life (HRQoL) has not been studied in this group. The aim was to study predictors of HRQoL in family members of patients with burns. Forty-four family members of adult patients treated in a burn center, between 2000 and 2007, completed questionnaires during care, and at 3, 6, and 12 months after injury. HRQoL was assessed with the EuroQol 5D (EQ-5D), which consists of the dimensions: mobility, self-care, usual activities, pain, and anxiety/depression. The questionnaire generates an EQ-5D index and a visual analog scale (VAS) score. Overall, the EQ-5D index was similar to that of the general population. A slight improvement in HRQoL was found in the VAS scores and in the anxiety/depression dimension over time. In regression models, HRQoL was primarily predicted by earlier life events, symptoms of post-traumatic stress disorder, and HRQoL, assessed during the patients’ hospitalization. In summary, HRQoL assessed with VAS scores increased slightly during the first year postburn, and early screening for life events and psychological symptoms, and HRQoL might be useful in identifying family members in need of support.

    The Anatomical Basis of the Lumbar Artery PerforatorFlap: A Cadaveric and Computer Tomography AngiogramStudy2016In: Clinics in Surgery Journal, ISSN 2474-1647, Vol. 1, article id 1270Article in journal (Refereed)
    Abstract [en]

    Background: Lumbar skin flaps based on cutaneous perforators arising from the lumbar artery have been described for coverage of lumbosacral defects and as free flaps for autologous breast reconstruction. Thus, the purpose of this study is to clarify anatomical aspects of the lumbar artery perforator flaps pertaining improvement in utility and design of this flap. Methods: Five fresh human bodies were dissected and twenty three-dimensional computed tomographic (CT) angiographic previously used for the evaluation of the deep inferior epigastric perforator flap in patients that underwent breast reconstruction were evaluated. All cutaneous lumbar artery perforators were analyzed for total number, location, and external diameter. Results: The number of perforators observed per side was 1.6±0.84 in the CT angiography and 3±1.05 in the cadaver study. Data from CT angiographies showed a mean diameter of the pedicle of 2.76±0.74 mm. This perforators were located at the mean distance from the midline (spinal process) of 76.56±6.97 mm, the mean length pedicle were 19.88±7.57 mm. Data from the cadaveric dissection study the mean diameter of the pedicle were 1.96±0.57 mm, the mean distance from the midline were 69.6±22.5 mm. Conclusion: The lumbar artery perforator flap is based on a perforator that has a predictable location and presents a good caliber. Versatility of design of a pedicled flap as a propeller, bilobed or transposition flap based on this reliable perforator can be useful to reconstruct complex defects in the lumbar area. Preoperative planning with CT angiography is recommended to assess the location and caliber of the perforator allowing a better design of the flap

    The Efficacy of Clinical Assessment in the Postoperative Monitoring of Free Flaps: A Review of 1140 Consecutive Cases2010In: Plastic and reconstructive surgery (1963), ISSN 0032-1052, E-ISSN 1529-4242, Vol. 125, no 4, p. 1157-1166Article in journal (Refereed)
    Abstract [en]

    Background: Effective postoperative monitoring of the vascular pedicle to a free flap can potentiate rapid return to the operating room in the setting of compromise, allowing for the potential to salvage the flap. The only ubiquitous method for postoperative monitoring of free flaps is clinical bedside monitoring, but although the use of clinical monitoring may be inferred in large reported series of free flaps, there has been little discussed in the literature of specific clinical outcome measures. Methods: The authors present their experience with 1140 consecutive cases of free tissue transfer and the use of clinical monitoring as a sole method of monitoring, and subgroup analysis of different recipient sites. Results: There were 94 take-backs, four of which had no pedicle compromise (false-positives) and there were four false-negatives. The overall flap salvage rate was 62.8 percent and the false-positive rate was 0.4 percent. Subgroup analyses demonstrated statistically significant differences between recipient sites for the false-positive rates: fewer false-positives with breast reconstruction cases (p < 0.05) and significantly more false-positives in the extremity group (p < 0.05). There was an improved flap salvage rate in cases of venous compromise compared with arterial compromise (69 percent versus 51 percent, p = 0.015). Conclusions: This largest reported series to date provides an outcome-based analysis of postoperative monitoring for free flaps, providing a benchmark standard against which adjunctive monitoring techniques can be compared. Future studies need to be assessed in the context of individual recipient sites, with significant differences in monitoring outcomes between sites.

    Reconstruction of late esophagus perforation after anterior cervical spine fusion with an adipofascial anterolateral thigh free flap: A case report.2017In: Microsurgery, ISSN 0738-1085, E-ISSN 1098-2752, Vol. 37, no 6, p. 684-688Article in journal (Refereed)
    Abstract [en]

    Reconstruction of late esophageal perforation usually requires flap surgery to achieve wound healing. However, restoring the continuity between the digestive tract and retropharyngeal space to allow for normal swallowing remains a technical challenge. In this report, we describe the use of a thin and pliable free adipofascial anterolateral thigh (ALT) flap in a 47-year-old tetraplegic man with a history of C5-C6 fracture presented with a large posterior esophagus wall perforation allowing an easier flap insetting for a successful wound closure. The postoperative course was uneventful and mucosalization of the flap was confirmed by esophagoscopy 4 weeks postsurgery. The patient tolerated normal diet and maintained normal swallowing during a follow-up of 3 years postoperatively. The adipofascial ALT flap may provide easier insetting due to the thin and pliable layer of adipofascial tissue for reconstructing large defects of the posterior wall of the esophagus by filling the retroesophageal space.

    Free anterolateral thigh flap and masseter nerve transfer for reconstruction of extensive periauricular defects: Surgical technique and clinical outcomes2017In: Microsurgery, ISSN 0738-1085, E-ISSN 1098-2752, Vol. 37, no 6, p. 479-486Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Radical tumor ablation in the periauricular area often results in extensive soft tissue defects, including facial nerve sacrifice, bone and/or dura defects. Reconstruction of these defects should aim at restoring facial reanimation, wound closure, and facial and neck contours. We present our experience using free anterolateral thigh flap (ALT) in combination with masseter nerve to facial nerve transfer in managing complex defects in the periauricular area.

    METHODS: Between 2011 and 2015 six patients underwent a combined procedure of ALT flap reconstruction and masseter nerve transfer, to reconstruct extensive, post tumor resection, periauricular defects. The ALT flap was customized according to the defect. For smile restoration, the masseter nerve was transferred to the buccal branch of the facial nerve. If the facial nerve stump was preserved, interposition of nerve grafts to the zygomatic and frontal branches was performed to provide separate eye closure. The outcomes were analyzed by assessing wound closure, contour deformity, symmetry of the face, and facial nerve function.

    RESULTS: There were no partial or total flap losses. Stable wound closure and adequate volume replacement in the neck was achieved in all cases, as well as good facial tonus and symmetry. The mean follow-up time of clinical outcomes was 16.8 months. Smile restoration was graded as good or excellent in four cases, moderate in one and fair in one.

    CONCLUSION: Extensive periauricular defects following oncologic resection could be adequately reconstructed in a combined procedure of free ALT flap and masseter nerve transfer to the facial nerve for smile restoration.

    Surgical technique: The intercostal space approach to the internal mammary vessels in 463 microvascular breast reconstructions2011In: Journal of Plastic, Reconstructive and Aesthetic Surgery, ISSN 1748-6815, Vol. 64, no 1, p. 58-62Article in journal (Refereed)
    Abstract [en]

    The internal mammary vessels are one of the most frequently used recipient sites for microsurgical free-flap breast reconstruction, and an accepted technique to expose these vessels involves removal of a segment of costal cartilage of the rib. However, in some patients, cartilage removal may result in a visible medial chest-wall depression that requires corrective procedures. We, therefore, use an intercostal space approach to the internal mammary vessels, as there is minimal disturbance of the costal cartilage with this technique. We have developed and performed our technique over an 8-year period in 463 microvascular breast reconstructions, and present it here as it contains modifications not previously described that may be of interest to other surgeons. There was no serious morbidity associated with the intercostal space approach, the internal mammary vessels were reliably and safely exposed in all these cases and the flap success rate was 95.8%.

    Discrimination between Glioma Grades II and III Using Dynamic Susceptibility Perfusion MRI: A Meta-Analysis2017In: American Journal of Neuroradiology, ISSN 0195-6108, E-ISSN 1936-959X, Vol. 38, no 7, p. 1348-1355Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: DSC perfusion has been evaluated in the discrimination between low-grade and high-grade glioma but the diagnostic potential to discriminate beween glioma grades II and III remains unclear.

    PURPOSE: Our aim was to evaluate the diagnostic accuracy of relative maximal CBV from DSC perfusion MR imaging to discriminate glioma grades II and III.

    DATA SOURCES: A systematic literature search was performed in PubMed/MEDLINE, Embase, Web of Science, and ClinicalTrials.gov.

    STUDY SELECTION: Eligible studies reported on patients evaluated with relative maximal CBV derived from DSC with a confirmed neuropathologic diagnosis of glioma World Health Organization grades II and III. Studies reporting on mean or individual patient data were considered for inclusion.

    DATA ANALYSIS: Data were analyzed by using inverse variance with the random-effects model and receiver operating characteristic curves describing optimal cutoffs and areas under the curve. Bivariate diagnostic random-effects meta-analysis was used to calculate diagnostic accuracy.

    DATA SYNTHESIS: Twenty-eight studies evaluating 727 individuals were included in the meta-analysis. Individual data were available from 10 studies comprising 190 individuals. The mean difference of relative maximal CBV between glioma grades II and III (n = 727) was 1.76 (95% CI, 1.27-2.24; P < .001). Individual patient data (n = 190) had an area under the curve of 0.77 for discriminating glioma grades II and III at an optimal cutoff of 2.02. When we analyzed astrocytomas separately, the area under the curve increased to 0.86 but decreased to 0.61 when we analyzed oligodendrogliomas.

    LIMITATIONS: A substantial heterogeneity was found among included studies.

    CONCLUSIONS: Glioma grade III had higher relative maximal CBV compared with glioma grade II. A high diagnostic accuracy was found for all patients and astrocytomas; however, the diagnostic accuracy was substantially reduced when discriminating oligodendroglioma grades II and III.

    Discrimination between primary low-grade and high-grade glioma with 11C-methionine PET: a bivariate diagnostic test accuracy meta-analysis2018In: British Journal of Radiology, ISSN 0007-1285, E-ISSN 1748-880X, Vol. 91, no 1082, article id 20170426Article, review/survey (Refereed)
    Abstract [en]

    Objective: To perform a meta-analysis evaluating the diagnostic accuracy of 11C-methionine (MET) positron emission tomography (PET) to discriminate between primary low-grade glioma (LGG) and high-grade glioma (HGG).

    Methods: A systematic database search was performed by a librarian in relevant databases with the latest search on 07 November 2016. Hits were assessed for inclusion independently by two authors. Individual patient data on relative MET uptake was extracted on patients examined pre-operatively with MET PET and subsequent neuropathological diagnosis of astrocytoma or oligodendroglioma. Individual patient data were analysed for diagnostic accuracy using a bivariate diagnostic random-effects meta-analysis model with restricted maximum likelihood estimation method. Bivariate meta-regression and subgroup analyses assessed study heterogeneity and validity. This study is registered with PROSPERO, number CRD42016050747.

    Results: Out of 1828 hits, 13 studies comprising of 241 individuals were included in the quantitative and qualitative analysis. MET PET had an area under the bivariate summary receiver operating characteristics curve of 0.78 to discriminate between LGG and HGG and a summary sensitivity of 0.80 with 95% confidence interval (CI) (0.66–0.88) and a summary false positive rate of 0.28, 95% CI (0.19–0.38). Heterogeneity was described by; bias in patient inclusion, study quality, and ratio method. Optimal cutoff for relative MET uptake was 2.21.

    Conclusion: MET PET had a moderately high diagnostic accuracy for the discrimination between primary LGG and HGG.

    Advances in knowledge: MET PET can be used as a clinical tool for the non-invasive discrimination between LGG and HGG with a moderately high accuracy at cut-off 2.21.

    Glioma Grade Discrimination with MR Diffusion Kurtosis Imaging: A Meta-Analysis of Diagnostic Accuracy2018In: Radiology, ISSN 0033-8419, E-ISSN 1527-1315, Vol. 287, no 1, p. 119-127Article in journal (Refereed)
    Abstract [en]

    Purpose: To assess the diagnostic test accuracy and sources of heterogeneity for the discriminative potential of diffusion kurtosis imaging (DKI) to differentiate low-grade glioma (LGG) (World Health Organization [WHO] grade II) from high-grade glioma (HGG) (WHO grade III or IV).

    Materials and Methods: The Cochrane Library, Embase, Medline, and the Web of Science Core Collection were systematically searched by two librarians. Retrieved hits were screened for inclusion and were evaluated with the revised tool for quality assessment for diagnostic accuracy studies (commonly known as QUADAS-2) by two researchers. Statistical analysis comprised a random-effects model with associated heterogeneity analysis for mean differences in mean kurtosis (MK) in patients with LGG or HGG. A bivariate restricted maximum likelihood estimation method was used to describe the summary receiver operating characteristics curve and bivariate meta-regression.

    Results: Ten studies involving 430 patients were included. The mean difference in MK between LGG and HGG was 0.17 (95% confidence interval [CI]: 0.11, 0.22) with a z score equal to 5.86 (P<.001). The statistical heterogeneity was explained by glioma subtype, echo time, and the proportion of recurrent glioma versus primary glioma. The pooled area under the curve was 0.94 for discrimination of HGG from LGG, with 0.85 (95% CI: 0.74, 0.92) sensitivity and 0.92 (95% CI: 0.81, 0.96) specificity. Heterogeneity was driven by neuropathologic subtype and DKI technique.

    Conclusion: MK shows high diagnostic accuracy in the discrimination of LGG from HGG.

    Return to work and health-related quality of life after burn injury2007In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 39, no 1, p. 49-55Article in journal (Refereed)
    Abstract [en]

    Objective: Although severe burn injury is associated with long-term rehabilitation and disability, research on returning to work in burn patients is limited. The aims of this study were: (i) to explore injury- and personality-related predictors of returning to work, and (ii) to compare health-related quality of life and health outcome in working versus non-working individuals.Design: Cross-sectional study.Subjects: Forty-eight former patients with pre-burn employment were evaluated on average 3.8 years after the burn.Methods: Data were collected from medical records and by a questionnaire in which the patients were asked about their main activity status described in the terms: work, studies, pension, disability pension, sick leave or unemployment. It also contained the Swedish universities Scales of Personality, SF-36, Burn Specific Health Scale-Brief, items assessing fear-avoidance, Impact of Event Scale-Revised and Hospital Anxiety and Depression Scale.Results: Thirty-one percent had not returned to work. In logistic regression, returning to work was associated with time since injury, the extent of full-thickness injuries, and the personality trait embitterment. Those who did not work had lower health-related quality of life, poorer burn-specific health, more fear-avoidance and more symptoms of post-traumatic stress disorder, but they did not differ from those who were working regarding general mood.Conclusion: Returning to work was explained by both injury severity and personality characteristics. Those who did not work were characterized by low health-related quality of life and poorer trauma-related physical and psychological health.

    Major depression and posttraumatic stress disorder symptoms following severe burn injury in relation to lifetime psychiatric morbidity2008In: Journal of Trauma - Injury, Infection and Critical Care, ISSN 0022-5282, Vol. 64, no 5, p. 1349-1356Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Psychiatric history has been suggested to have an impact on long-term adjustment in burn survivors. A rigorous, prospective, longitudinal approach was used to study psychiatric history in a population-based burn sample and its impact on symptomatology of depression and posttraumatic stress disorder (PTSD) at a 12-month follow-up. METHODS: Seventy-three consecutive patients admitted to the Uppsala Burn Unit were assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition for psychiatric disorders, of whom 64 were also assessed after 12 months. RESULTS: Forty-eight patients (66%) presented with at least one lifetime psychiatric diagnosis; major depression (41%), alcohol abuse or dependence (32%), simple phobia (16%), and panic disorder (16%) were most prevalent. At 12-months postburn, 10 patients (16%) met criteria for major depression, 6 (9%) for PTSD, and 11 (17%) for subsyndromal PTSD. Patients with lifetime anxiety disorder and with lifetime psychiatric comorbidity were more likely to be depressed at 12 months, whereas those with lifetime affective disorder, substance use disorder and psychiatric comorbidity were more likely to have symptoms of PTSD. CONCLUSIONS: Two-thirds of burn survivors exhibit a history of lifetime psychiatric disorders. Those with a psychiatric history have a higher risk of postburn psychiatric problems.

    Medical and biological factors affecting mortality in elderly residential fire victims: a narrative review of the literature2017In: Scars, Burns & Healing, Vol. 3Article in journal (Refereed)
    Abstract [en]

    For older people (aged over 65 years), the risk of dying in a residential fire is doubled compared to the general population. Obvious causes of death mainly include smoke inhalation and burn injuries. That older people are more fragile and have more concurrent diseases is inherent, but what is it that makes them more vulnerable? It is known that the number of elderly people is increasing globally and that the increased risk of death in fires can be explained, at least in part, by physical and/or cognitive disabilities as well as socioeconomic and behavioural factors. The possibility that medical illnesses and an aging organism/tissues might explain this increased risk has not been shown to the same extent. Therefore, this narrative literature review focuses on medical and biological explanations. An initial search using the terms ‘elderly’, ‘fatal’, ‘residential’ and ‘fire’ yielded some interesting articles. Using a broader snowball search also accepting grey literature, several additional risk factors could be identified. Cardiovascular diseases, in particular atherosclerotic heart disease, greatly increases the vulnerability to, for example, carbon monoxide and probably also other asphyxiating gases. Cardiovascular diseases and lack of physical fitness may also increase vulnerability to heat. Burned elderly patients are also at a higher risk of death than younger patients, but it is controversial whether it is age itself or the pre-existing illnesses that come with age that increase the risk. Immunosenescence, malnutrition and female gender are other risk factors for poorer outcome after burns, all of which are common among older people.

    Impact of personality disorders on health-related quality of life one year after burn injury2015In: Disability and Rehabilitation, ISSN 0963-8288, E-ISSN 1464-5165, Vol. 37, no 6, p. 534-540Article in journal (Refereed)
    Abstract [en]

    Purpose: Personality disorders (PDs) are associated with significant distress, disability, and cause great difficulties in life. PDs have been suggested to influence adaptation after major burns, but the potential relationship has not been fully elucidated. This study aimed to describe the prevalence of PDs in 107 patients with major burn injury, and to identify the impact of PDs on perceived patient outcome assessed as health-related quality of life (HRQoL) one year after burn. Methods: One burn-specific instrument (Burn Specific Health Scale-Brief (BSHS-B)) and two generic instruments (EuroQol Five Dimensions and Short Form 36 Health Survey) were used, and Psychiatric Axis I and II disorders were assessed one year post burn. Results: This study identified an above normal prevalence of PDs among individuals afflicted by burn, and participants with PD had a significantly larger lifetime burden of Axis I disorders compared to participants without PD. Participants with PDs scored significantly lower than those without PD in the BSHS-B domain Skin involvement, and the effect of having a PD was related to the subscale Treatment regimens. There was no relationship between the presence of PD and generic HRQoL. Conclusions: An implication of these observations is that special rehabilitation efforts including more tailored interventions must be offered to these patients to ensure that the obstacles they perceive to caring for themselves in this respect are eliminated.

    Thermal injuries in the insensate deep inferior epigastric artery perforator flap: case series and literature review on mechanisms of injury2009In: Microsurgery, ISSN 0738-1085, E-ISSN 1098-2752, Vol. 29, no 3, p. 214-217Article, review/survey (Refereed)
    Abstract [en]

    With the increasing use of the deep inferior epigastric artery perforator (DIEP) flap, complications that are particularly rare (less than 1%) may start to become clinically relevant. During DIEP flap harvest, cutaneous nerves innervating the flap are necessarily sacrificed, resulting in reduced sensibility This impaired sensibility prevents adequate thermoregulatory reflexes, like vasodilatation, sweating, and protective behaviors, leaving the reconstructed breast considerably more susceptible to thermal insult. We present four DIEP flap cases who sustained postoperative thermal injury to the reconstructed breast. All four cases were operated on between 2001 and 2008, over the course of 600 DIEP flaps in our unit (an incidence of 0.7%). The injuries occurred between 2 and 18 months after reconstruction. Two patients sustained thermal injury while sunbathing, one while staying in a warm environment, and one sustained the injury while taking a shower. No flap losses ensued, but these were not without morbidity. A literature review discusses other similar cases in the literature and describes the mechanisms for these findings. As a majority of patients will regain both fine-touch and heat sensation by 3 years postoperatively, it is pertinent that prophylactic measures be instituted during this period, such as the avoidance of sunbathing and the use of cooler shower temperatures for the first 3 years postoperatively. While performing sensory nerve coaptation is the gold standard for maximizing the success of sensory regeneration, this is not always sought and the 0.7% incidence of thermal injury we have encountered suggest the role for greater consideration of such injury.

    How long are fasciocutaneous flaps dependant on their vascular pedicle: A unique case of SIEA flap survival2010In: Journal of Plastic, Reconstructive and Aesthetic Surgery, ISSN 1748-6815, Vol. 63, no 4, p. E347-E350Article in journal (Refereed)
    Abstract [en]

    Background: While it has long been held that muscle flaps maintain their dependency on their vascular pedicle for the long term, fasciocutaneous flaps have been less well investigated. Recent studies of the deep inferior epigastric artery perforator (DIEP) flap have suggested that these flaps may maintain long term dependence on their vascular pedicles for survival. There is no literature concerning these effects in the superficial inferior epigastric artery (SIEA) flap. Case report: We describe a unique case in which the pedicle of a superficial inferior epigastric artery (SIEA) flap for breast reconstruction was avulsed 11 days postoperatively, with the flap surviving on its inferior wound edge alone. Conclusion: Fasciocutaneous flaps may lose dependency on their vascular pedicles in the short term following transfer, developing alternative pathways for vascular supply and ultimately survival. A conservative approach early in the course of flap compromise due to perforator ligation or avulsion, in cases where immediate re-anastomosis may not be feasible, is thus supported.
