Extradigital glomus tumor as a cause of chronic perianal pain.

Glomus tumor is a rare perivascular benign tumor arising from the Sucquet-Hoyer canal of the normal glomus body, most commonly in the digital areas. We report a serving soldier with such a tumor in an atypical site, the perianal region, presenting with episodic shooting pain. Total surgical excision was performed. Histopathology revealed a well-circumscribed tumor composed of clusters of monotonous polygonal cells surrounding capillary-sized blood vessels. Tumor cells also showed immunopositivity for smooth muscle antigen and vimentin. Following excision, the patient was completely relieved of pain and there was no recurrence on follow-up for 6 months.

Investigation of an outbreak of chikungunya in Malegaon Municipal areas of Nasik district, Maharashtra (India) and its control.

BACKGROUND & OBJECTIVES: An outbreak of chikungunya fever occurred in Malegaon town of Nasik district of Maharashtra state, India during February and March 2006. A total of 4530 fever cases were reported during this period including 1781 cases which were admitted in different hospitals of the town. An entomological and epidemiological investigation was carried out in the affected villages during the outbreak to study the possible causes of the outbreak and to isolate the virus responsible. METHODS: Entomological evaluation was done as per WHO guidelines. Sera samples were collected by venipuncture from clinically suspected chikungunya patients in hospitals and also during house-to-house survey in affected villages. IgM antibodies to dengue virus were detected using IgM capture ELISA (PANBIO) and by "Haemagglutination inhibition test" for detection of antibodies against Chikungunya virus. Acute sera samples were inoculated in cell lines for virus isolation. The isolates were confirmed by RT-PCR. RESULTS: On investigation, it was found that water storage containers like cement tanks, plastic containers or earthen pots placed in front of the individual houses were the potential breeding sites for Aedes aegypti. Entomological survey carried out in the most affected areas revealed high Aedes indices. House, container and breteau indices were found to be 27.2, 16.19 and 35.1, respectively. Out of the 13 acute sera samples collected, virus was isolated in 10 samples. The isolates were confirmed by RT-PCR and sequencing using primers from nsP1 gene of Chikungunya virus (CHIKV, Accession No. EF077609, EF077610). Of the 17 convalescent sera tested, significant level of HI antibodies to CHIKV was detected in five samples. One sample was positive for IgM antibodies against dengue virus. Based on clinico-epidemiological features and laboratory findings, the illness was confirmed to be of chikungunya viral disease. CONCLUSION: Control measures targeting the vector population and personal protective measures against the mosquito bites were instituted. Extensive IEC campaign with the involvement of community and religious leaders helped in containment of the disease.

Extraserosal pedunculated leiomyoma of stomach.

Leiomyoma of the stomach, a type of gastrointestinal stromal tumor, is uncommon. We report a 51-year-old woman with an extraserosal pedunculated leiomyoma of the stomach.

Hepatic resection for benign liver pathology--report of two cases.

Hepatic resection for benign pathology is rare. We report our experience in two patients with hepaticolithiasis. One patient underwent left hemihepatectomy with removal of segments II, III and IV for localized Caroli's disease with multiple intrahepatic calculi. The second patient underwent resection of segment II and III with Roux-en-Y hepaticojejunostomy for right and left intrahepatic calculi with an abscess in the left lobe of the liver and a choledochal cyst.

Metastatic amelanotic melanoma.

We report a 60 year-old-man who presented with generalized abdominal colicky pain. He had a history of left great toe dysarticulation done for amelanotic melanoma one year ago. Investigations were suggestive of metastases of melanoma to the small intestine. Exploratory laparotomy with segmental ileal resection and anastomosis was performed. Histological examination showed features of amelanotic melanoma characterized by absence of melanin pigment.

Massive lower intestinal bleeding--a decade of experience.

BACKGROUND: Lower gastrointestinal bleeding is defined as hemorrhage orginating distal to the ligament of Treitz. Its diagnosis is difficult, often requiring endoscopy, angiography and isotope scans. METHODS: All patients with massive lower gastrointestinal bleeding seen in three gastroenterology centers of Armed Forces during an 11 year period between 1988 and 1999 were retrospectively analysed. RESULTS: A total of 91 patients with massive lower gastro intestinal bleeding were seen during 11 years. The mean age of the patients was 38.9 years and 64 were males. Aetiological diagnosis was: Non-specific ulcers--11, Ileal tuberculosis--8, NSAID enteropathy--8, Enteric fever--7, Meckel's diverticulum--7, Polyps--6, Ulcerative colitis--5, Carcinoma colon--5, Colonic diverticulosis--5, No cause found--5, Polyposis coli--5, Jejunal diverticulae--3, Angiodysplasia colon--3, Radiation colitis--3, Ischaemic colitis--3, Ileal tumor--2, Ileal angiodysplasia--2, Intestinal Lymphoma--2, Bechet's syndrome--1. Bleeding stopped on conservative therapy in 18 patients (including 5 where no diagnosis could be made). Diagnosis was made in 36 patients on fiber-optic colonoscopy done during active bleeding. Remaining patients were subjected to emergency laparotomy and diagnosis was obvious on inspection of abdominal contents in 25 cases. The diagnosis was finally made in remaining 12 cases by intraoperative endoscopic examination through an ileotomy. Four patients died, only one of them due to rebleed after surgery from an additional lesion. CONCLUSIONS: Compared with experience in Western countries, massive lower gastro-intestinal hemorrhage in India affects younger patients, has different causes and carries a lower mortality. Colonoscopy is useful in making diagnosis during active lower intestinal bleeding in about one-third cases. Exploratory laparotomy and Intra-operative endoscopy are complimentary to above examination and can make the diagnosis in most of the remaining cases.

Selection of donors and organization of a donor system for liver transplantation in India.

Organ transplantation has been a major scientific advance of this century. There is an attempt to start liver transplantation (LTx) in India in the near future. Donor selection is an integral part of the transplantation programme. Donor organs are a scarce resource and optimising their use will not only contribute to the success of the programme but also will ensure a steady flow of donors in the long term. Various factors essential for consideration while selecting a donor for liver transplantation are discussed. I have suggested guidelines for organising a viable donor system in the Indian setting to make the transplant programme long lasting.

The contribution of "cure by dapsone monotherapy' to the reduction of prevalence of leprosy in the State of Orissa, India, 1983-1993.

The implementation of multiple drug therapy (MDT) in the State of Orissa, India, started in early 1983 and was extended in a phased manner to nine out of the then total of 13 districts by 1993. As part of a programme to bring the remaining four districts under MDT, an intensive screening of the registers was carried out in early 1993. From a total of 28,855 cases registered in these districts, 26,113 (90.5%) were examined and 18,008 (69.9%) deleted. The deleted included patients who had died, emigrated, double (or occasionally treble) entries for the same patient and those in whom careful re-assessment suggested that the original diagnosis of leprosy had been wrong. In addition, however, 8,260 (45.8%) of the 18,008 cases deleted were considered to have been cured by dapsone monotherapy. This figure, from districts with a relatively poor development of services for leprosy control, prompted a retrospective examination of data from the other (more privileged) nine districts. This revealed that from a total of 264,000 patients screened, prior to the implementation of MDT from 1983 onwards, 75,590 (28.6%) were removed from the registers, and that of these, 63,562 (84.0%) were considered to have been cured by dapsone monotherapy. Thus from a total of 93,598 patients removed from registeres in this State since 1983, 71,822 (76.7%) have been assessed as cured by dapsone monotherapy. The significance of this finding and its apparently considerable contribution to the overall reduction in the prevalence of leprosy in Orissa, 1983-1993, is discussed.

Prostaglandin E2 gel for cervical priming and induction of labour in unfavourable cervical state.

To know the safety and efficacy of intracervical prostaglandin E2 gel over conventional intravenous infusion of oxytocin for priming and induction of labour, a prospective study was undertaken in 96 cases selected at random for both study and control series consisting 48 cases in each group with definite indication for termination of pregnancy having unfavourable cervical state. Periodic clinical assessment in different groups following the procedure revealed that by the end of 12 hours, 39 cases in the study and 28 cases in the control group had uterine contraction. Foetal heart rate abnormality was more marked in the oxytocin group (1.56% in the study group and 20.31% in the control group) while increase in Bishop's cervical scoring was noticed more often in the prostaglandin group. By the end of 12 hours of initiation of therapy, 17 cases in the study group and only 3 cases in the control group had spontaneous vaginal delivery. There was significant shortening of instillation and delivery interval in PGE2 group. The number of caesarean section in the study group was only 16.66% in comparison to 25% in the control group. Analysing the efficacy of the procedures adopted, the success rate in the prostaglandin group was 91.66% in contrast to 64.58% in the oxytocin group.

Portal hypertension in a western Indian hospital.

The profile of Portal Hypertension (PHT) in India is different from the west. Despite a good liver our patients are prone to die due to massive haematemesis as they are located far away from the referral centres. Drugs have a limited role and endoscopic sclerotherapy has its own limitations in our setting. Surgery (proximal lieno-renal shunt) is a one time treatment, removes the injury prone huge spleen and cures hypersplenism. We report our experience of 36 patients managed by this procedure.

Dieulafoy's lesion: a rare cause of massive upper gastrointestinal haemorrhage.

Out of 900 cases of Upper Gastrointestinal haemorrhage seen during 1985-1989, 6 (0.67%) cases had Dieulafoy's lesion as the causative factor. All patients presented with massive upper gastrointestinal haemorrhage. The mean age of the patients was 46.3 year (32-60 yrs) and 4 were males and 2 females. No consistent associated medical factors could be identified. The diagnosis was established by emergency endoscopy which showed an active arterial spurter in 4 patients and located the bleeding site to be close to the fundus in other 2 patients. Injection sclerotherapy tried in 3 patients was not successful. Four patients had bleeding lesion along the greater curvature close to the fundus and two had on posterior wall but all within 6 cm. of gastroesophageal junction. All patients underwent curative emergency surgery with wedge resection of the lesion. We conclude that Dieulafoy lesion should be suspected in a patient with massive, recurrent and obscure upper gastrointestinal bleeding. Emergency endoscopy for diagnosis and prompt surgical intervention can cure the lesion which is potentially fatal if untreated.
