ABSTRACT
Obscure gastrointestinal bleeding accounts for nearly 5% of all gastrointestinal haemorrhage and is frequently due to a lesion in the small bowel. We report the case of a male patient with obscure overt gastrointestinal bleed in whom repeated upper gastrointestinal endoscopy, colonoscopy, computed tomography scanning and exploratory laparotomy showed no specific pathology. However, on capsule endoscopy done subsequently, a small polyp in the jejunum was located and resected. Histology revealed an aggressive angiomyxoma. This type of small bowel lesion has not been reported in the literature before.

Giant cell reparative granuloma is an infrequent non-tumoral lesion affecting the maxillary and mandibular bones and only rarely, the cranial bones. We report a case of giant cell reparative granuloma of the base of the skull in a 12-year-old female who presented with a parapharyngeal mass. Computerized Tomography (CT) showed the intracranial extension and destruction of surrounding bones.

In an experiment, application of different levels of metalaxyl to a sandy loam soil significantly affected the nodulation and nitrogenase activity of mungbean. In both the compost amended and unamended soils, 0.5 mg kg(-1) of metalaxyl enhanced acetylene reduction activity and yield of mungbean, where as higher concentrations (1 mg and 2.5 mg kg(-1) of fungicide) inhibited the nodulation traits as well as economic traits of mungbean.

Thirty patients of hemoptysis with a normal skiagram chest were evaluated by computed tomography. Majority of the patients were between 21 to 50 years of age. Seventy percent had mild hemoptysis while 30 percent had moderate hemoptysis. Computed tomography provided diagnostic information in 16 patients (53%). The various aetiologies were bronchiectasis (20%), tuberculosis (20%), pneumonia (6.7%), bronchial carcinoid in one case and allergic bronchopulmonary aspergillosis in one case. Computed tomography may play a role in screening patients who present with hemoptysis with normal chest radiographs.

Twenty patients of obstructive jaundice were subjected to percutaneous transhepatic cholangiography (PTC) of which 17 were operated on. Patients were divided in 4 groups according to the site of obstruction. The diagnostic signs observed were: Complete block with interface having convexity downwards (4), convexity upwards (3), biconcave caudal cut off (6), smooth edged cut off (one), irregular edged cut off (one) and non-specific appearance (one); incomplete block with interface having convexity upwards (one); biconcave caudal cut off (2) and multiple smooth central filling defects (2). In one case there was incomplete obstruction at two sites giving rise to two different signs. PTC was 100% correct in accurately telling the site of lesion. As regards the nature of the lesion the diagnosis on PTC was found correct in 15 out of 17 cases (88.5%).

Computed tomograms of 107 patients of head trauma in the paediatric age group were evaluated. Generalised brain swelling (44%) and falx sign (44%) were the commonest findings observed in the computed tomograms. The overall mortality was 16.8% of which all except one were those with Glasgow coma scale between 3 and 7.
