During a retrospective review of more than 1,000 pediatric pancreas specimens obtained by autopsy or biopsy, 13 cases of primitive interstitial pancreatitis (PIP) were identified. The morphologic diagnosis of PIP is based on the following histological features: presence of abundant, inspissated, PAS-negative intraductal secretions, overdistension and focal rupture of the intrapancreatic ducts, and presence of a focal, extensive inflammatory infiltrate. PIP should be distinguished from cystic fibrosis, necrotizing pancreatitis, and passive secondary interstitial infiltrates associated with extensive retroperitoneal cellulitis caused by septicemia or abdominal surgery. Clinical diagnosis is difficult and was not considered in the ten children under four years of age. In the three children over five, the presence of recurrent abdominal pain with mild ascitis and jaundice led to the correct diagnosis. Pathological findings suggest two possible pathophysiologic hypotheses: lesions may develop proximal to a mechanical malformative obstruction that is, however, only very rarely found, according to a more likely alternative, quantitative and qualitative modifications of pancreatic secretions may occur as a result of severe dehydration or use of drugs (corticosteroids, diuretics), justifying the term "dyschylic pancreatitis" coined by G. Seifert.

Inpatient and community-based care can be complementary in relation to the management of HIV disease. Medical records from 200 inpatients of Chikankata Hospital near Lusaka, Zambia and 200 home based patients were examined and compared for the common symptoms of presentation of HIV disease, associated opportunistic infections, and treatment protocols. Drug costs of both groups were also compared. The most common respiratory symptoms in the 2 groups are cough, chest pains, weight loss, and hemoptysis. Treatment employed for these symptoms were cortimoxazole, penicillin V, erthromycin, and tetracycline. Acetyl saliclic acid and paracetamol were used for pain relief in both groups. Gastointestinal system symptoms for both groups were diarrhea, weight loss, abdominal pain, and vomiting. Cotrimoxazole and metronidazole were used in treating diarrhea. Additional treatment protocol for the 2 patient samples included oral rehydration therapy for dehydration, antacid or bismuth subsalicylate for diarrhea and enteritis, and mycostatin for oral candidiasis. Central nervous system symptomatology included headache, dementia, neckace, and lethargy. Chloramphenicol was employed in treating bacterial meningitis. Diazepam and chlorpromazine were effective for restless patients. Genito-urinary system symptomatology for the 2 groups included dysuria, genital ulcers, hematuria, viral warts, and buboes. Antibodies were used for sexually transmitted diseases and infections. Skin symptomatology included rash and dermatitis, herpes zoster, abscess, kaposi's sarcoma, ulcers, furunculosis, and discharging anal sinus. In treating these symptoms, hospital based care and home based care were similar. Overall, it was found that hospital treatment protocols were detailed, expensive, and time consuming. Furthermore, hospital treatment for HIV positive patients is more expensive than HIV negative patients; hospital costs for 50 HIV negative patients totaled US$415.94 compared to US$1204.98 HIV positive/PTB negative patients and US$1705.62 for HIV positive/PTB positive patients. Drug cost/patient admission is increased by 469% if HIV positive. (author's modified).

Cryptosporidia are important causative agents of acute diarrhea among children in tropical countries. The leading symptoms are watery diarrhea lasting from 2 to 8 weeks and vomiting accompanied by crampy abdominal pain. Dehydration occurs frequently. The prevalence of cryptosporidia infections is much higher in tropical regions (an average of up to 10%) than in moderate regions. Cryptosporidia infections are dependent both on the children's age (highest rates among children below 2 years of age) and the season. In most studies, the highest incidence was found during the rainy season. Children who were breast-fed showed lower rates of infection. The transmission is fecal- oral, especially from animals to humans, from person to person, but also by way of contaminated drinking water. For an exact description of the epidemiology of cryptosporidia infections in the tropical countries, especially of the transmission, the seasonal differences and the breast feeding patterns, further studies are needed.

Renal vein thrombosis in early infancy is a complication of dehydration and prolonged hypotension. The onset is usually acute and the most common clinical signs are uni- or bilateral frank masses, hematuria, proteinuria and thrombocytopenia. In most cases, with conservative management, the late outcome is favorable. In the adult, renal vein thrombosis is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis. Clinically, the presentation of a sudden complete occlusion is that of severe abdominal and lumbar pain with hematuria and loss of function of the kidney that suffers hemorrhagic infarction. Physical examination often reveals an enlarged kidney. With gradual occlusion, renal function is preserved. The initial diagnostic approach is with ultrasound studies and computed tomography; definitive diagnosis is established by renal venography or by selective renal arteriography. In general, a conservative approach including the use of anticoagulant treatment is preferred to surgical intervention. Priapism is a persistent painful penile erection due to ischemic or non-ischemic causes; therapeutic intracavernosal injection of papaverine is becoming the most common cause. In early and mild stages, aspiration of blood from the corpora cavernosa supplemented with intracavernosal irrigation with alpha-stimulating agents is the procedure of first choice; in late and severe ischemia, a shunt procedure may become necessary. Hepatic vein thrombosis occurs in association with a number of conditions considered predisposing factors including the use of oral contraceptives. The clinical picture may be that of an acute illness with abdominal pain, hepatomegaly, ascites and hepatic failure as well as early death. More often, the onset is insidious with slowly developing ascites and wasting. For the diagnosis, hepatic scintigraphy may be helpful but, at present, ultrasonography, computed tomography and magnetic resonance scanning are procedures of choice. There is, as yet, no adequate treatment. A fatal outcome may be prevented by surgical decompression of the congested liver and, in recent years, liver transplantation has been employed. Portal vein thrombosis, in children, is usually considered a complication of umbilical sepsis or a result of a congenital abnormality of the portal vein. In adults, the most frequent causes are hepatic cirrhosis and neoplasia. Clinically, there may be a sudden appearance of ascites with resolution in a symptom-free interval until the onset of other features of portal hypertension occur. Currently, ultrasound real-time imaging supplemented with Doppler capability, computed tomography and magnetic resonance scanning provide the necessary diagnostic information. Variceal hemorrhage is often the first major complication requiring treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

A large granulosa cell tumor was believed to be responsible for causing obstruction and subsequent rupture of the small colon in a 10-year-old Quarter Horse mare. Two months earlier, a mass, tentatively diagnosed as granulosa cell tumor of the left ovary, had been identified by means of rectal palpation and ultrasonography. The mare was evaluated for clinical signs of acute, severe, abdominal pain, increased heart rate, cyanotic mucous membranes, clinical dehydration, with high PCV, leukopenia, and extreme abdominal distension. A large soft tissue mass and taut band that constricted the lumen of the small colon were palpable per rectum. Septic peritonitis was diagnosed on the basis of results of abdominocentesis. Exploratory surgery revealed extensive fecal contamination of the abdominal viscera, and the mare was euthanatized because of the resultant poor prognosis. At necropsy, the small colon was occluded by a taut, left broad ligament and the ovarian mass that was proved to be a granulosa cell tumor. The occlusion had caused impaction of the small colon, with subsequent perforation at the level of the broad ligament.

In a prospective one year study, comprising children with acute gastroenteritis admitted to hospital or treated as outpatients, the clinical and laboratory features of rotavirus diarrhoea (168 cases) were compared with those of enteric adenovirus (32 cases), bacterial (42), mixed (16), and non-specific (135) infections. The rotavirus disease was remarkably consistent, with a sudden onset of vomiting, a high frequency of fever and dehydration, and a mean duration of diarrhoea of 5.9 days. Outpatients excreting rotavirus had a similar but milder illness, mainly on account of less pronounced vomiting. The predominant symptom of enteric adenoviruses was long lasting diarrhoea (mean 10.8 days). Abdominal pain, bloody stools, prolonged diarrhoea (mean 14.1 days), leucocytosis, and a raised erythrocyte sedimentation rate strongly suggested a bacterial aetiology. Mixed infections caused longer lasting diarrhoea (mean 8.0 days) than rotavirus alone, but the severity of the illness was not increased. The clinical features of infection with unidentified pathogens most resembled those of bacterial infections. Respiratory symptoms were not significantly associated with any particular pathogen. Hypernatraemia and complications were uncommon. This study showed that the clinical features of gastroenteritis with rotavirus, enteric adenoviruses, and bacteria each exhibited patterns that could guide the experienced clinician to a presumptive diagnosis.

Polyethylene glycol electrolyte lavage solution was compared with a 10 percent mannitol solution for preoperative colonic cleansing. Eighty patients were prepared randomly with one of these solutions on the afternoon prior to surgery. Colonic cleansing was better with polyethylene glycol electrolyte lavage (90 percent optimal cleansing vs. 75 percent). Analysis of hematologic, biochemical, and weight changes before and after the bowel preparation, demonstrated a mild subclinical dehydration with the use of mannitol. Evaluation of patient tolerance demonstrated more nausea, cramps, and abdominal pain with mannitol. Other symptoms were similar with both preparations. Colonic hydrogen gas was sampled during surgery, and two patients in the mannitol group had combustible levels. This study confirms that both 10 percent mannitol and polyethylene glycol electrolyte lavage are safe, effective methods of preoperative bowel cleansing. Better cleansing, patient tolerance, and lower hydrogen gas level make polyethylene glycol electrolyte lavage the preferred method.

The objective of this study was to identify those patients in whom mesenteric venous thrombosis (MVT) is likely to develop and to review the pathophysiology, clinical presentation, diagnostic modalities, and patient outcome. We present a review of the literature from 1911 to 1984 with respect to 372 patients with MVT, including five of our own patients. Data on 99 of these patients were obtained from autopsy reports and were not included in the study. This disease is common in the sixth and seventh decades of life, with 81% of these older patients having associated illnesses. MVT involves segments of the small bowel, but rarely of the colon, with hemorrhagic infarcts rather than gangrene. This disease does not conform to a pattern, although a prodromal period of days or weeks of abdominal pain (which is usually out of proportion to physical findings), marked leukocytosis, and dehydration are all highly suggestive of MVT. Serosanguineous fluid obtained by means of peritoneal tap is a useful diagnostic tool. A high index of suspicion, early diagnosis, and prompt surgical intervention with the addition of anticoagulants seems to improve survival and reduce recurrence.

Human infections caused by Aeromonas spp. are being reported with increased frequency. We examined 1012 unselected stool specimens from 799 children for various pathogens, including Aeromonas spp., to evaluate the clinical associations of Aeromonas spp. in the stools of children in the East End of London. A total of 33 children had positive cultures for Aeromonas spp. These were identified as: Aeromonas hydrophila (16), A. sobria (9), A. caviae (8). Aeromonas spp. were identified by being oxidase positive in character, a property that distinguishes Aeromonas spp. from Enterobacteriaceae. Associated pathogens included Salmonella typhimurium (1), Campylobacter spp. (3), Enteropathogenic Escherichia coli (2), and Giardia lamblia (1). Electron microscopic examination of the stool of 13 children revealed viral particles in two, rotavirus (1), and coronavirus-like particles (1). The associated clinical features in the 25 children with only Aeromonas excretion were diarrhea (21), vomiting (10), abdominal pain (9), fever (4), and mild dehydration (2). Five patients had macroscopic blood loss in the stools. The illness was generally mild and lasted only a short time.

A yearling Holstein heifer was admitted with abdominal pain and bilateral, ventral abdominal distention. Bladder rupture was diagnosed by abdominocentesis and endoscopy. Correction of metabolic derangements was accomplished by volume diuresis, with maintenance of a urethral catheter before surgical repair of the bladder. The cause of the bladder rupture was believed to be related to adhesions resulting from previous surgery for urachal abscessation. Bladder rupture, which usually occurs in bulls or steers secondary to urolithiasis or in cows after dystocia, also should be considered in prepartum heifers with dehydration, abdominal pain, and abdominal distention.
