Effect of four-layer dressing on the microbiological profile of venous leg ulcer.

OBJECTIVE: Venous leg ulcer (VLU) is a chronic disease and has periods of exacerbation and remission. Various bandage systems-single-layered, double-layered and multiple-layered with elastic and non-elastic components-have been developed. The requirement for sustained pressure brought about the introduction of the four-layer bandage. We studied the bacteriology of VLUs and the effect of four-layer bandages on their healing. METHOD: Clinical details of all patients, with wound size measurement by gauze piece, wax paper and scale, were recorded. The wounds were initially debrided and photographic records of all patients were maintained. Patients were followed up every week, when the dressings and four-layer bandages were changed. RESULTS: A total of 60 patients were recruited to the study with four patients having bilateral disease and so a total of 64 VLUs were evaluated. Of these, 60 (93.8%) healed completely, one (1.6%) healed partially and three (4.7%) did not heal. After excluding the four VLUs that did not fully heal, 10 (16.7%) had recurrence while 50 (83.3%) had no recurrence in the follow-up period, which lasted for one year. During the first visit (baseline), meticillin-resistant Staphylococcus aureus (MRSA) was isolated in 29 (45.31%) VLUs and Pseudomonas spp. in 20 (31.25%) VLUs. With subsequent dressing, the VLU size decreased and the culture of the VLU was sterile from the third culture onwards in 45 cases. There was a significant correlation (p<0.001) between VLU size and the number of dressings. CONCLUSION: Compression therapy is the mainstay of treatment of VLU, with rapid healing and improvement in bacteriological profile. Compression in the range of 30-40mmHg is the most effective treatment for uncomplicated VLUs with adequate arterial competency.

Liver Resection for Giant Hepatic Cavernous Hemangioma.

Liver hemangiomas are common. Giant liver hemangiomas are rare and symptomatic patients require treatment. Surgery is the curative procedure. Other options such as intra-arterial embolization may be used to decrease the volume and bleeding of these lesions. Three cases of giant liver hemangioma were treated with liver resection, one with left lateral hepatectomy and two with right lateral hepatectomy. All patients had made an uneventful recovery with no recurrence at 3-year follow-up. Most hemangiomas are small, asymptomatic, and do not require any treatment. Liver resection is a safe and effective treatment for giant hemangiomas.

Expression analysis of aryl hydrocarbon receptor repressor (AHRR) gene in gallbladder cancer.

BACKGROUND: The aryl hydrocarbon receptor repressor (AHRR), a member of the growing superfamily, is a basic helix-loop-helix/PerAHR nuclear translocator (ARNT)-Sim (bHLH-PAS) protein. AHRR has been proposed to function as a putative new tumor suppressor gene based on studies in multiple types of human cancers. This current study aims to investigate AHHR expression and its prognostic significance in gallbladder cancer. METHODS: The study includes 48 gallbladder cancer and 34 chronic cholecystitis cases as controls. The expression level of AHRR was analyzed by using semi-quantitative PCR and immunohistochemical staining. The results were correlated with different clinical parameters. RESULTS: We demonstrate that the expression of AHRR is significantly down-regulated in gallbladder cancer tissue samples as compared to that in chronic cholecystitis tissue samples by reverse transcriptase PCR (RT-PCR) (P = 0.017) and immunohistochemistry analysis (P = 0.002). Interestingly, our RT-PCR data revealed that AHRR mRNA expression is frequently down-regulated (45.8%; 22/48) in cases as compared to 14.7% (5/34) in controls. Similarly, immunohistochemical analysis data show significant down-regulation of AHRR expression in 77.1% (37/48) of gallbladder cancer cases than 44.1% (15/34) in controls (P < 0.017). Reduced mRNA and protein expression is significantly associated with advanced T-stage (P = 0.001), histological differentiation (P = 0.001), and tumors with nodal metastasis (P = 0.001). Decreased expression of AHRR is significantly associated with poor prognosis in gallbladder cancer patients. CONCLUSION: In conclusion, the present study suggests that low AHRR expression may be critical in gallbladder cancer development. Our data suggests that AHRR may act as a tumor suppressor gene and its expression profile may be useful as a diagnostic marker in gallbladder cancer.

Digital glomus tumor: An experience of 57 cases over 20 years.

BACKGROUND: Glomus tumors are rare tumors and may affect any area of the body, but digits, palms, and soles are commonly affected due to higher number of glomus body. We present our experience with the management of 57 cases of glomus tumors of the fingertips treated over a period of 20 years (2000-2019). MATERIALS AND METHODS: Medical records of 57 cases with glomus tumors treated over a period of 20 years were reviewed for patient demographics, presenting characteristics, duration, previous treatment history, physical examination, investigation, treatment, follow-up, and recurrence. RESULTS: In our study, the mean age was 49 years, with age 47 years among women and 53 years among men suggesting glomus tumor as a disease of past middle age. The total number of cases was 57 with 44 women and 13 men. Site of lesion was nail bed in 50 cases (87.7%) and tip of finger in 7 cases (12.3%). In clinical assessment pinpoint tenderness was present in all 57 cases (100%) and pain in 56 cases (98.8%). Other features at the time of presentation were nodularity in 38 cases (66.6%), deformed nail in 14 cases (24.6%), and cold hypersensitivity in 20 cases (35.1%). The mean duration of the disease was 2.3 years (1.2-5.6 years). CONCLUSION: One of the most painful clinical conditions confirmed by comprehensive clinical assessment and cured dramatically by complete surgical excision.

Study of association of varicose veins and inflammation by inflammatory markers.

OBJECTIVE: In varicose veins, increased levels of inflammatory markers are indicators of endothelial damage and increased procoagulant activity. These findings support the assumption that the constitution of blood in varicose veins differs from that of systemic blood. The purpose of the study was a correlative study of blood constituents in varicose veins and peripheral veins (normal vein) in same individual with varicose vein which was done by comparing the level of concentration of interleukin-6, fibrinogen, haemoglobin from blood of varicose veins and normal peripheral vein (antecubital vein). METHOD: Using citrated plasma samples withdrawn from arms and legs of same patient and plasma obtained by centrifugation of citrated venous blood at 5000 r/min for 10 min was used for correlation. Serum concentration of interleukin-6 and fibrinogen were determined by human enzyme-linked immunosorbent assay Kit for both interleukin-6 and fibrinogen, which is based on the standard sandwich enzyme-linked immunosorbent assay technology. This assay employs a monoclonal antibody specific for human interleukin-6 coated on a 96-well plate. RESULT: Expressed as median (interquartile range) in pg/mL, leg samples from patient having varicose vein has significantly increased interleukin-6 in cases as compared to controls (p value of <0.001). Leg samples from patient having varicose vein has significantly increased fibrinogen concentration than their arm samples (p value of <0.001). Concentration of haemoglobin significantly increased in leg samples as compared to blood withdrawn from arms (p value of 0.012). CONCLUSION: Blood withdrawn from the site of varicose vein appears to have significantly increased concentration of interleukin-6, fibrinogen and haemoglobin when compared to same patient's antecubital blood sample supporting the hypothesis that inflammation is increased in tissues drained by varicose vein.

Assessment and grading of pigmentation in chronic venous insufficiency.

INTRODUCTION: Chronic venous insufficiency causes skin pigmentation of the leg ranging from small patches of mild dyschromia to extensive areas of severe skin pigmentation. It is thought that the pigmentation is mainly due to haemosiderin or melanin deposition. Erythrodiapedesis which occurs as a result of venular hypertension causes erythrocytes to migrate across the microvascular network into the dermis. METHODS: We categorized the grading of pigmentation into four grades: +, few spots; ++, pigmentation over gaiter area; +++, pigmentation involving leg and ankle; ++++, heavily pigmented (dark). Skin biopsies were taken from the patient while undergoing surgery; two biopsies were taken from each patient, one from apparently normal skin and other from the site of pigmentation. A total of 45 patients diagnosed as chronic venous insufficiency with pigmentation were included in the study and five patients included in control. The biopsy specimens were sent to pathology department for H&E, Perls stain and IHC for S100. RESULTS: Majority of cases, i.e. 62% of limbs fall under (++) grade of pigmentation, followed by (+) grade of pigmentation in 20%, while (+++) and (++++) constitute 9% of the cases each. Increased melanin deposition was seen in 40 pigmented skin biopsies and 3 normal skin biopsies from the case group, and normal melanin deposition was seen in all the non-varicose controls. CONCLUSION: We have tried to categorize pigmentation in chronic venous insufficiency into four grades. As the grade of pigmentation increases the per cent of cases with ulceration is increasing. It was observed that presence of melanin deposition irrespective of the grade of pigmentation was distributed more towards the advanced clinical classification (C5 and C6).

Jejunal angiodysplasia causing recurrent gastrointestinal bleeding presenting as severe anaemia and melena.

Angiodysplasia of the gastrointestinal (GI) tract consists of ectasia of the submucosal vessels of the bowel. The evaluation of such patients needs proctoscopy, colonoscopy, small bowel enema, enteroscopy, capsule enteroscopy and angiography. Capsule enteroscopy has come up as an alternative to GI enteroscopy and colonoscopy in patients with occult GI bleeding; up to 52% cases of small bowel angiodysplasia in patients with occult GI bleed with negative upper GI and colonoscopy have been reported. The use of capsule enteroscopy potentially limits the hazard of radiation exposure from angiography and is less invasive than double balloon endoscopy. The treatment options for angiodysplasias include intra-arterial vasopressin injection, selective gel foam embolisation, endoscopic electrocoagulation and injection of sclerosants, with each of these being technically demanding, and requiring centres with good access to enteroscopy technology and trained gastroenterologists. Operative intervention has been indicated for refractory bleeding or lesions in sites not accessible to endoscopic interventions.

Fibroadenoma in axilla: another manifestation of ectopic breast.

Fibroadenoma of an accessory breast is a rare disease. The clinical significance lies in the fact that a number of cystic, inflammatory, neoplastic diseases similar to those of a normal breast have been reported in accessory breasts as well. Vigilant self-assessment and complete clinical examination are always encouraged to detect earliest malignancy in the axilla. We report two cases of ectopic breast fibroadenoma with the relevant literature.

Pancreatic pseudocyst: therapeutic dilemma.

Pancreatic pseudocyst develops in both acute and chronic pancreatitis. It is an entity likely to either remain asymptomatic or develop devastating complications. Despite being diagnosed easily, treatment exercise is still at crossroads whether in the form of internal or external drainage or endoscopic, laparoscopic, or open intervention with a good radiological guidance. The therapeutic dilemma whether to treat a patient with a pancreatic pseudocyst, as well as when and with what technique, is a difficult one. This paper is intended to get information about diagnostic and therapeutic exercises most appropriate for acute and chronic pancreatic pseudocyst.

Effect of autologous epidermal cell suspension transplantation in chronic nonhealing wounds: a pilot study.

BACKGROUND: Chronic nonhealing wounds are difficult to manage. Various substances are being used to heal these wounds. We sought to observe the effects of autologous epidermal cell suspension dressings on chronic nonhealing ulcers. METHODS: We enrolled patients of the wound clinic at University Hospital, Varanasi, India, with nonhealing wounds of more than 6 weeks' duration. We treated the wound beds with sterile dressings and antibiotics until the swab cultures became sterile. We prepared autologous epidermal cell suspensions from skin grafts and used them on the ulcer beds along with Vaseline gauze dressings. Follow-up visits with patients occurred weekly for assessment of wound healing and other changes. RESULTS: Fifteen patients enrolled in our study. Of these, 6 patients had completely healed at 12 weeks, 1 patient at 16 weeks and 2 patients at 20 weeks after treatment. We observed a slow healing response in 6 patients, of whom 1 patient had healed completely at 32 weeks and another at 48 weeks. One patient needed skin grafting, and 3 patients were lost to follow-up. CONCLUSION: Autologous noncultured epidermal cell suspension transplantation seems to be an effective, simple and time-saving method to treat chronic nonhealing wounds.

A case series describing 118 patients with lower limb necrotizing fasciitis.

Necrotizing fasciitis of the lower limb is not uncommon, with poor outcome. This study reviewed 118 cases (78 males and 40 females) with mean age of 45 + 16.5 years (range 12-95 years) of lower limb necrotizing fasciitis admitted to the Department of Surgery, BHU in India between 1995 and 2007. Most patients (n = 97) presented with fever. Other presenting symptoms included painful swelling, bullae, erythema, ulcer, and necrosis. Comorbid conditions such as diabetes, tuberculosis, malignancy, and immunosuppressive therapy were associated in 72 (61%) cases. Amputations were done in 24 patients. Thirty one patients developed septic shock. Renal dialysis was done in 16 patients and ventilatory support was needed in 12 patients. The most common organism identified was beta-hemolytic streptococci (n = 42). Eighteen patients died, a mortality of 15%. The authors consider early diagnosis and aggressive surgical intervention to be crucial for the successful treatment of disease.

Results of a one-day, descriptive study of quality of life in patients with chronic wounds.

Quality of life is a subjectively interpreted phenomenon that can be profoundly altered by the presence of a wound. Particularly when complete and expedient healing seems unrealistic, quality of life becomes the focus of care. To assess the influence of a variety of chronic wounds on patient quality of life, a 1-day, descriptive study was conducted among 50 consecutive outpatients (64% men, 36% women; age range 14 to 78 years) with chronic wounds who attended the Wound Clinic of the University Hospital, Varanasi, India. A quality-of-life questionnaire containing six parameters (physical activities, feelings, household duties, leisure time activities, social relations, and general activities) was developed and administered. Demographic information was available as a result of a previous study at this institution. Quality-of-life scores were grouped as satisfactory and unsatisfactory and participants were grouped by age (<30 years old, 30 to 60 years old, >60 years old). Wounds were classified by cause (diabetes, venous disease, pressure ulcer, and tuberculosis) and size (<10 cm2, 10 to 50 cm2, >50 cm2). The most common site was the lower limb or foot (39, 78%), followed by upper limb (six, 12%) and head, neck, and trunk (five, 10%). More than half (28, 56%) of all patients had an unsatisfactory overall quality-of-life score. The percentage of patients with satisfactory scores was higher in patients with smaller versus larger wounds and wounds located on upper rather than lower limbs, as well as in middle-aged versus younger or older patients. This patient-centered instrument helped document important quality-of-life concerns among chronic wound patients.

Iatrogenic femoral artery aneurysms in orthopaedic practice.

BACKGROUND: Iatrogenic injury to the femoral vessel is a rare complication after fracture of hip. Pseudoaneurysm formation of superficial femoral artery or profunda femoris artery is detected quite late. We present our experience for surgical management of pseudoaneurysm of femoral artery after iatrogenic trauma during management of fracture of femur. METHODS: A retrospective analysis was carried out for eight patients with femoral artery pseudoaneurysm treated surgically during the last 10 years in one surgical unit. RESULTS: Of eight patients with pseudoaneurysm of femoral artery, six had superficial femoral artery aneurysm and two profunda femoris artery aneurysm. Mean duration for presentation was 4 months (range 2-6 months). Methods of surgical intervention were direct closure of arterial defect after aneurysmectomy in six cases and use of saphenous vein patch graft for repair of artery in two cases. Mean size of aneurysm was 12 x 7 cm (range 8 x 4 cm to 20 x 12 cm). All patients were doing well during a mean follow up of 72 months (range 6-110 months). CONCLUSION: Large pseudoaneurysms of femoral arteries after iatrogenic injury during management of fractures of femur should be managed by aneurysmectomy and arterial repair with or without saphenous vein patch graft.

Colonic carcinoma with multiple small bowel perforations mimicking intestinal obstruction.

BACKGROUND: Carcinoma of the colon may present with perforation proximal to the site of malignancy. Caecum is the commonest site of perforation if the ileocecal valve is patent and the jejunal and ileal perforations are very rare. CASE PRESENTATION: A 35 year male presented with intestinal obstruction. Emergency laparotomy revealed carcinoma of the transverse colon with multiple pinpoint perforations along antimesenteric border of ileum, which were wrapped with omentum, and no peritoneal contamination was present. Extended right hemicolectomy with jejunocolic anastomosis was done. Patient made uneventful recovery in postoperative period and was treated with adjuvant chemotherapy. CONCLUSION: Patients with colonic carcinoma and incompetent ileocecal valve may present with intestinal perforation. Increased intraluminal pressure and closed loop obstruction may lead to ischemia and perforation of the small bowel.
