Stool samples of 1488 children suffering from acute diarrhoea were studied for bacterial culture and sensitivity. Shigella culture was positive in 143 (10 per cent) children and 53 hospitalized children could be studied in detail. Thirty-six (68 per cent) children were under 2 years of age and peak prevalence was observed in summer months. Fever and diarrhoea were universal features; 96 per cent had blood and mucus in the stools, but 32 per cent started with watery diarrhoea lasting 1-3 days followed by dysentery. Two cases (4 per cent) had watery diarrhoea. Abdominal pain dehydration, and malnutrition were present in more than two-thirds of the cases. Central nervous systemic (CNS) manifestations, renal failure, respiratory manifestations, and subacute intestinal obstruction were seen in 45, 25, 17, and 5 per cent of cases, respectively. Shigella dysenteriae was the commonest organism grown in 57 per cent, followed by Shigella flexneri in 36 per cent, Shigella boydii in 4 per cent, and Shigella sonnei in 4 per cent cases. In the majority, the organisms were sensitive to neomycin (83 per cent), furazolidine (86 per cent), and cephaloridine (87 per cent), whereas Shigella strains were resistant to tetracycline in 93 per cent, ampicillin in 83 per cent, chloramphenicol in 91 per cent and cotrimoxazole in 66 per cent cases. Proctosigmoidoscopy was useful in defining the nature of mucosal lesion, to collect swabs for culture and biopsy specimen for histopathology. Four (8 per cent) cases had pseudomembrane and in two cases Clostridium difficile could be identified. Eight (15 per cent) cases died and two of them had shigellaemia.(ABSTRACT TRUNCATED AT 250 WORDS)

The differential diagnosis of small intestinal infections is broad, making the identification and management of these disorders challenging. The majority of cases of acute diarrhea are self-limited and do not require diagnostic evaluation or treatment. Most patients do not require specific therapy, and treatment should focus on fluid and electrolyte replacement. In patients with severe, persistent, or chronic diarrhea, a careful medical history and routine stool testing are helpful in determining the cause. Pathogen-specific therapy should be given in patients in whom a pathogen is identified. In those without an identifiable pathogen, antidiarrheal agents are helpful in reducing the number of bowel movements and preventing further dehydration. Endoscopy may be helpful in patients with severe diarrhea and a negative stool evaluation, particularly in HIV-infected patients with chronic diarrhea. Surgery has a limited role in the management of small intestinal infections, but may be lifesaving in patients with intestinal perforation or small bowel obstruction.

Colovesical fistulas (CVFs) are rare complications of very advanced cancers of the abdominal or pelvic cavity and often cause diagnostic troubles. CVFs are found more often in males, whereas females usually suffer from rectovaginal or vesicovaginal fistulas. This article presents a case of a female patient who was admitted to the hospital because of acute diarrhea, presumably of infectious origin, and with only subtle abnormalities in blood tests and urinalysis. Owing to the ineffectiveness of the performed treatment and progressive intensification of symptoms, diagnostics were extended to include a computed tomography scan, sigmoidoscopy and cystography. The imaging results revealed a large heterogeneous conglomerate of solid and fluid structures in the pelvis, which involved reproductive organs, the bladder and sigmoid colon. The excrement leaking from the digestive tract was urine, and CVF was the first manifestation of colon cancer. Shortly after the final diagnosis, the patient deteriorated and eventually died after an urgent colostomy was performed because of a bowel obstruction.
