Secondary reconstruction of below knee amputation stump with free anterolateral thigh flap

Below knee stump preservation reduces ambulatory energy expenditure and improves the quality of life. Reconstruction of soft tissue loss around the stump is a challenging task. Below knee stump reconstruction demands stable skin with sufficient soft tissue to allow weigh bearing. Microsurgical tissue transfer is increasingly being used as a salvage option. Anterolateral thigh flap with additional vastus lateralis muscle provides extra cushioning effect. We report two cases of amputation below knee successfully salvaged. The anterolteral flap with abundant tissue and stable skin offers a reliable option for cover. Two patients with below knee amputation were reconstructed secondarily. After 6 to 20 months of follow -up, stumps showed no signs of pressure effects. Patients are able to bear 50-70 hours of weight per week.     

Role of Fibrin Glue as a Sealant to Esophageal Anastomosis in Cases of Congenital Esophageal Atresia with Tracheoesophageal Fistula

Objective The aim of this study was to characterize a successful approach for the management of infants with long-gap esophageal atresia (EA) with tracheoesophageal fistula (TEF). The goal was to preserve the native esophagus and minimize the incidence of esophageal anastomotic leaks using fibrin glue as a sealant over the esophageal anastomosis. Method A total of 52 patients were evaluated in this study. Only patients in whom, gap between the two ends of the esophagus was ≥ 2 cm were selected during January 2005 to January 2007. Patients were divided in two groups on the basis of block randomization. Group A comprised the patients in whom fibrin sealant was used as reinforcement on a primary end-to-end esophageal anastomosis; in group B, fibrin glue was not used. The two groups were compared in terms of esophageal anastomotic leak (EL), postoperative esophageal stricture (ES), and mortality. The statistical analysis was done using Fisher’s exact test and the chi-squared test. Result The number of anastomotic leaks in group A (glue group) was about one-fifth that in group B (no glue group). The incidence of ES was almost twice as high in group B as in group A. The mortality rate was almost threefold higher in group B (no-glue group). The higher incidence of EL and ES in group B compared to group A was statistically significant. Conclusion Thus, fibrin glue when used as an adjunct to esophageal anastomosis for primary repair of long-gap EA with TEF appears safe in the clinical setting and may lower the chances of esophageal leak and anastomosis-site strictures. Hence, it can diminish the mortality and morbidity of these patients.     

Health-related quality of life and functioning of middle-aged and elderly adults with bipolar disorder

OBJECTIVE: Data characterizing bipolar disorder in older people are scarce, particularly on functional status. We evaluated health-related quality of life and functioning (HRQoLF) among older outpatients with bipolar disorder as well as the relationship of HRQoLF to bipolar illness characteristics. METHOD: We compared community-dwelling middle-aged and older adults (age range, 45 to 85 years) with bipolar disorder (N=54; mean age=57.6 years), schizophrenia (N=55; mean age=58.5 years), or no psychiatric illnesses (N=38; mean age=64.7 years) on indicators of objective functioning (e.g., education, occupational attainment, medical comorbidity) and health status (e.g., Quality of Well-Being scale [QWB] and the Medical Outcomes Study-Short Form Health Survey [SF-36]). Within the group with bipolar disorder, we examined the relationship between HRQoLF and clinical variables (e.g., phase and duration of illness, psychotic symptoms, cognitive functioning). RESULTS: Patients with bipolar disorder were similar in educational and occupational attainment to the normal comparison group, but they obtained lower scores on the QWB and SF-36 (with large effect sizes). Compared with schizophrenia, bipolar disorder was associated with better educational and work histories but similar QWB and SF-36 scores and more medical comorbidity. Patients in remission from bipolar disorder had QWB scores that were worse than those of normal comparison subjects. Greater severity of psychotic and depressive symptoms and cognitive impairment were associated with lower HRQoLF. CONCLUSIONS: Bipolar disorder was associated with substantial disability in this sample of older adults, similar in severity to schizophrenia. Remission of bipolar disorder was associated with significant but incomplete improvement in functioning, whereas psychotic and depressive symptoms and cognitive impairment seemed to contribute to lower HRQoLF.     

Steatocholecystitis: the influence of obesity and dietary carbohydrates

INTRODUCTION: We have recently demonstrated that obese and lean mice fed a high fat diet have increased gallbladder wall fat and decreased gallbladder contractility, cholecystosteatosis. Animal and human data also suggest that diets high in refined carbohydrates lead to gallstone formation. However, no data are available on the role of dietary carbohydrates on gallbladder wall fat and inflammation. Therefore, we tested the hypothesis that both obesity and dietary carbohydrates would increase gallbladder fat and cytokines, steatocholecystitis. METHODS: At 8 wk of age, 47 lean and 22 obese female mice were fed a 45% carbohydrate (CHO) diet while an equal number of lean and obese mice were fed a 75% CHO diet for 4 wk. All mice underwent cholecystectomy, and the gallbladders were snap-frozen. Individual and total lipids were measured by gas chromatography. Interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha, and IL-6 were measured by enzyme-linked immunosorbent assay. Data were analyzed by analysis of variance and Tukey test. RESULTS: Gallbladder total fat, triglycerides, and cholesterol were maximum (P < 0.001) in obese mice on the 75% CHO diet. Gallbladder TNF-alpha and IL-1beta as well as serum cholesterol levels showed a similar pattern (P < 0.001). Gallbladder saturated free fatty acids and IL-6 levels were highest (P < 0.001) in obese mice on the 45% CHO diet. CONCLUSIONS: These data suggest that (1) both obesity and dietary carbohydrates increase gallbladder total fat, triglycerides, cholesterol, TNF-alpha, and IL-1beta and (2) obesity also increases gallbladder free fatty acids and IL-6. Therefore, we conclude that obesity is associated with steatocholecystitis and that a high carbohydrate diet exacerbates this phenomenon.     

Subcutaneous hyalohyphomycosis caused by Fusarium in a kidney transplant recipient

Fusarium is a filamentous opportunistic pathogenic fungus responsible for superficial as well as invasive infection in immunocompromized hosts. Net state of immunosuppression and cytomegalovirus (CMV) infection appear to predispose to this disease which is life-threatening when disseminated. Though infections with Fusarium have been widely described in hematological malignancies and hematopoietic stem cell transplant cases, they have been reported to be rare in solid organ transplant recipients, are often localized and carry a favorable prognosis. We here describe a rare case of subcutaneous non-invasive infection with Fusarium in a renal allograft recipient two and half years after transplantation. Patient had a previous history of CMV infection along with multiple other recurrent co-infections. Diagnosis was based on culture of tissue specimens yielding Fusarium species. The infection had a protracted course with persistence of lesions after treatment with voriconazole alone, requiring a combination of complete surgical excision and therapy with the anti-fungal drug.     

Persistent sciatic artery aneurysm with limb-threatening ischemia

A 50 year old lady with bilateral persistent sciatic artery aneurysm presented with severe limb ischemia due to distal embolization from a thrombus filled persistent sciatic artery aneurysm on one side. Persistent sciatic artery is a rare embryological anomaly which results due to the failure of development of the femoral system. Its complete variant can be clinically recognised by the presence of a weak femoral pulse with a normal popliteal pulse. The diagnostic and treatment considerations of this rare anomaly are described.
