Intrapancreatic gastric duplication cyst presenting as lower gastrointestinal bleeding.

This report describes a rare foregut malformation of a noncontiguous gastric duplication cyst embedded within the body and tail of the pancreas. An 8-month-old boy presented with massive malena of 3 days' duration. The laparotomy showed an intrapancreatic cyst with bleeding and ulcer perforation into a loop of adherent jejunum. Histologically, the cyst contained gastric mucosa. This is believed to be the first reported instance of an intrapancreatic gastric duplication causing massive lower gastrointestinal bleeding in an infant.

Pigmented vagal paraganglioma.

Paragangliomas are uncommon and those arising from the vagal trunk are rarer. Pigmented extra-adrenal paragangliomas are still rarer and reported sites of occurrence are the uterus, spine, retroperitoneum, bladder, mediastinum and orbit. The presence of abundant pigment in a cervical paraganglion has not been reported previously. We report one such unusual case of pigmented vagal paraganglioma that arose from the vagal trunk below the nodose ganglion, had massive central necrosis and showed hypovascularity on angiography. The unusual features and difficulties in the diagnosis of such cases are discussed.

Epidemiology of Helicobacter pylori and peptic ulcer in India.

BACKGROUND: There is a wide variation in the prevalence of peptic ulcer in India both before and since the use of endoscopy. We studied the prevalence of peptic ulcer disease in a community in northern India and its relationship with Helicobacter pylori infection. METHODS: A house-to-house survey of residents aged 15 years or above in a sub-sector of Chandigarh was performed as part of a pilot survey. Subsequently, the study randomly covered all sectors of Chandigarh and we screened 2649 persons. A questionnaire was administered to each subject by trained staff. All individuals with history of peptic ulcer/dyspepsia and an equal number of asymptomatic individuals were asked to attend the outpatient department of the Institute. Diagnosis of peptic ulcer was based on endoscopy or history of previous ulcer surgery. RESULTS: Two hundred and fifty-four individuals attended the outpatient department at the Institute and 147 underwent endoscopy, biopsy for histology and rapid urease test, and blood was collected for H. pylori serology. There were 80 symptomatic and 67 asymptomatic individuals. Helicobacter pylori was positive in 38 (56.7%) asymptomatic and 49 (61.3%) symptomatic individuals (P > 0.05). The point prevalence of active peptic ulcer was 3.4% and the lifetime prevalence was 8.8%. The duodenal-to-gastric ulcer ratio was 12:1. Helicobacter pylori was present in 11/13 (84.6%) subjects with peptic ulcer. Peptic ulcer was more common in elderly and dyspeptic individuals and there was no effect of sex or socioeconomic status. Helicobacter pylori was associated with age only and did not depend on sex, socioeconomic status or dyspepsia. Of the 38 asymptomatic persons having H. pylori infection, none had active peptic ulcer. CONCLUSIONS: This study demonstrates frequent occurrence of peptic ulcer and H. pylori in this part of the country. Peptic ulcer was more prevalent in the elderly and dyspeptic subjects. Helicobacter pylori was not associated with dyspepsia, and was more prevalent in elderly subjects. There was a low prevalence of peptic ulcer in asymptomatic H. pylori-infected persons in this community.

Epithelioid hemangioendothelioma of middle ear masquerading as glomus tumor.

Hemangioendothelioma is still one of the less-known tumors of vascular origin. The authors report the case of a 38-year-old man who presented with unilateral, nonpulsatile timnitus, aural fullness, and a sense of imbalance. Imaging showed a contrast enhancing soft tissue mass lesion involving the external auditory canal and middle ear, mimicking as glomus tumor. Histopathological examination of surgical specimen showed it to be hemagioendothelioma.

Multiple spontaneous enterocutaneous fistulae in malakoplakia.

Malakoplakia is a rare chronic inflammatory disease, usually involving the urogenital tract. We report a patient who presented with a psoas abscess, and later developed colocutaneous fistula at the site of abscess drainage and multiple spontaneous fistulae away from the site of incision. Histology of the resected specimen showed Michaelis-Gutmann bodies, which are diagnostic of malakoplakia.

Comparison of multidetector computed tomographic colonography and conventional colonoscopy for detection of colorectal polyps and cancer.

BACKGROUND: Computed tomographic colonography (CTC) is a new technique for detecting colonic neoplasms. Data on the utility of this method in the Indian population are limited. METHODS: Forty-two patients with symptoms of colonic disease underwent CTC and conventional colonoscopy (CC) within one week of each other and the findings at these two investigations were compared. RESULTS: The entire colon could be evaluated in 38 patients on CTC and in 23 patients on CC. Of the 19 patients who had incomplete CC, 14 had occlusive colonic lesions. Of the 86 lesions detected on CC, 76 (88.4%) were correctly identified on CTC with regard to location and size. CTC was false negative for 10 lesions and false positive for 5 lesions in 3 patients. The sensitivity and specificity of CTC were 65% and 77%, respectively, for lesions 1-5 mm; 97% and 83% for 6-9 mm-sized lesions; and 100% and 100% for lesions 10 mm or larger. Extracolonic findings were seen in 24 of 42 patients (57%). CONCLUSIONS: CTC is reliable for detecting lesions 6 mm or larger in size. It permits evaluation of the region proximal to an occlusive growth, which is often not possible with CC.
