The Superficial Inferior Epigastric Artery Based Abdominal Flap for Reconstruction of Extensive Defects of the Hand and Forearm: A Modified Design With Primary Closure of the Donor Site.

INTRODUCTION: The reconstruction of the hand and forearm targets the restoration of their function and aesthetic appearance. Inferiorly based abdominal flaps are reliable and versatile flaps that can cover large defects of the forearm and hand. Here we present a modified abdominal flap design based exclusively on the superficial inferior epigastric artery (SIEA) to reconstruct the hand and forearm's extensive defects. The donor site is closed primarily. METHODS: This is a retrospective study of the patients who underwent reconstruction of hand and forearm defects with SIEA flap from 2006 to 2018. The flap was designed on the ipsilateral hemiabdomen with a narrow pedicle based on the SIEA. We describe the anatomical basis and the outcomes of SIEA flap for reconstruction of the hand and forearm's extensive defects. RESULTS: Forty-eight soft tissue defects of the hand and forearm were reconstructed with the SIEA-based abdominal flap. Twenty-nine (60.41%) dorsal defects, 4 (8.33%) volar defects, 4 (8.33%) circumferential defects, 6 (12.5%) hand amputation stump, and 5 (10.41%) finger and thumb defects were covered using the SIEA flap. Forty-seven (97.91%) flaps had complete survival, whereas 1 (2.08%) flap had distal necrosis at the time of division. One (2.08%) flap had marginal necrosis, and 1 (2.08%) flap had distal necrosis after the division. The donor site was closed primarily in all patients. One (2.08%) patient had wound dehiscence at the abdominal donor site. All flaps gave excellent coverage with a satisfactory contour. CONCLUSION: Abdominal flap based on SIEA is a safe, reliable, and versatile flap for the reconstruction of extensive soft-tissue defects of the hand and forearm. An ability to provide a large amount of skin and soft tissue and the abdominal donor site's primary closure make it a favorable option for upper limb reconstruction in regions with limited resources and technical expertise.

Impact of burn contractures of chest wall and their surgical release on pulmonary function.

BACKGROUND: Extensive burn scars and contractures are likely to restrict the movements of the chest wall which may affect the pulmonary ventilation by restricting its expansion during inspiration. We designed this study to evaluate the effect of burn contractures of chest wall on pulmonary function and to estimate the effect of contracture release on pulmonary functions in patients with compromised PFT. METHODS: Pulmonary function tests (PFT) of 20 patients having chest wall contractures involving more than 50% of the chest circumference were studied. Restrictive lung disease was defined as forced vital capacity (FVC) value less than 80% of predicted normal for the age, weight, and height of that patient. Patients with a restrictive pattern on PFT were subjected to the surgical release of the contracture. PFT was repeated one month after the surgery which was compared with the initial report. RESULTS: Of the 20 patients included in the study, 5 (25%) patients had a restriction pattern on PFT. 1 patient had a mild restriction, 2 patients had moderate restriction and 2 patients had a severe restriction of pulmonary function. The mean duration of contracture was 58.2±15.75months in patients with a pulmonary restriction as compared to 29.87±6.21months in patients with a normal PFT (p=0.001). All patients having a restrictive pattern on PFT had contracture involvement of >75% of the chest wall circumference (p=0.0036). The mean forced vital capacity (FVC) increased from 1.94L preoperatively to 2.11L after surgical release of the contracture (p=0.047). However, the restriction pattern in PFT did remain. CONCLUSION: Long standing chest wall contractures and contractures involving >75% of the chest circumference are likely to cause a restrictive pattern on PFT. Any significant improvement of pulmonary function after surgical release of the contracture is unlikely.

Sympathetic dysfunction dermatitis in a revascularised upper extremity after near-total amputation - A case report and review of literature.

Commonly reported complications after revascularisation or replantation of extremity are vascular thrombosis leading to complete or partial failure, bony non-union or malunion, joint stiffness and incomplete or abnormal sensory recovery. Sympathetic dysfunction dermatitis is an unreported complication after revascularisation or replantation surgery which results due to denervation of the extremity. We report a case of a young adult who developed eczematous dermatitis over the revascularised upper limb and discuss the role of sympathetic dysfunction in the development of these skin lesions. The patient was successfully treated with a short course of oral and topical steroids. Sympathetic dysfunction dermatitis is a rare form of skin eruptions occurring in the revascularised or replanted part of an extremity due to abnormal sympathetic function in the affected part.

A prospective analysis of risk factors for pediatric burn mortality at a tertiary burn center in North India.

BACKGROUND: None of the available mortality predicting models in pediatric burns precisely predicts outcomes in every population. Mortality rates as well as their risk factors vary with regions and among different centers within the regions. The aim of this study was to identify socio-demographic and clinical risk factors for mortality in pediatric burns in an effort to decrease the mortality in these patients. METHODS: A prospective analytical study was conducted in patients up to the age of 18 years admitted for burn injuries in a tertiary care burn center in India from January to December 2014. Clinical and demographic data was collected through questionnaire-interview and patient follow-up during their stay in the hospital. Univariate and multivariate firth logistic regression was used to identify various risk factors for mortality in pediatric burns. RESULTS: A total of 475 patients were admitted during the study period. Overall mortality was 31.3% (n = 149) in this study. Mean age of the patients who died was 8.68 years. Of the 149 deaths, 74 were males and 75 were females (male to female ratio = 0.98). Mean total body surface area (TBSA) involved of the patients who expired was 62%. Inhalational injury was seen in 15.5% (n = 74) of pediatric burn admissions. Mortality was significantly higher (74.3%) in patients with inhalation injury. Mortality was highest in patients with isolates of Acinetobacter + Klebsiella (58.3%), followed by Pseudomonas + Klebsiella (53.3%), Acinetobacter (31.5%), and Pseudomonas (26.3%) (p < 0.0005). Factors found to be significant on univariate firth analysis were older age, female gender, suicidal burns, higher TBSA, presence of inhalation injury, increased depth of burn, and positive microbial cultures. On multivariate analysis, higher TBSA was identified as an independent risk factor for mortality. The adjusted odds ratios for TBSA involvement was 21.706 (25.1-50%), 136.195 (50.1-75%), and 1019.436 (75.1-100%), respectively. CONCLUSION: TBSA is the most important factor predicting mortality in pediatric burns. The higher the TBSA, the higher is the risk of mortality. Other significant risk factors for mortality are female gender, deeper burns, positive wound cultures, and inhalation injury. Risk of mortality was significantly lower in children who belonged to urban areas, nuclear family, who sustained burn injury in the last quarter of the year, and who stayed in the hospital for longer period.

Epidemiology of pediatric burns and future prevention strategies-a study of 475 patients from a high-volume burn center in North India.

BACKGROUND: Pediatric burns have a long-term social impact. This is more apparent in a developing country such as India, where their incidence and morbidity are high. The aim of this study was to provide recent prospective epidemiological data on pediatric burns in India and to suggest future preventive strategies. METHODS: Children up to 18 years old admitted to the Department of Burns, Plastic & Maxillofacial Surgery, VMMC & Safdarjung Hospital, New Delhi, between January and December 2014 were included in the study. Data regarding age, sex, etiology, total body surface area (TBSA), circumstances of injury, and clinical assessment were collected. The Mann-Whitney test or Kruskal-Wallis test or ANOVA was used to compare involved TBSA among various cohort groups accordingly. Univariate and multivariate linear regression analyses were used to determine the predictors of TBSA. RESULTS: There were a total of 475 patients involved in the study, including seven suicidal burns, all of whom were females with a mean age greater than the cohort average. Age, type of burns, mode of injury, presence or absence of inhalation injury, gender, and time of year (quarter) for admission were found to independently affect the TBSA involved. Electrical burns also formed an important number of presenting burn patients, mainly involving teenagers. Several societal issues have come forth, e.g., child marriage, child labor, and likely psychological problems among female children as suggested by a high incidence of suicidal burns. CONCLUSIONS: This study also highlights several issues such as overcrowding, lack of awareness, dangerous cooking practices, and improper use of kerosene oil. There is an emergent need to recognize the problems, formulate strategies, spread awareness, and ban or replace hazardous substances responsible for most burn accidents.
