A 31-year-old man was hospitalized for evaluation of chronic diarrhea accompanied by profound dehydration, abdominal pain, nausea, vomiting, and low-grade fever. He had been identified as hepatitis B surface antigen-positive in 1983 and HIV antibody-positive two years later. In 1987, after a diagnosis of Pneumocystis carinii pneumonia, he had been placed on zidovudine and prophylactic pentamidine. Subsequently, thrush developed, which was treated with nystatin. The patient's gastrointestinal symptoms were of about six months' duration and originally had responded fairly well to diphenoxylate. More recently, however, he had been losing weight steadily and had required emergency room rehydration on two occasions. A search for stool ova and parasites and routine enteric pathogens, conducted by the outpatient department, had revealed Cryptosporidium cysts.

A total of 4,409 stool specimens from infants less than 5 years of age seeking treatment for diarrhea in Matlab, Bangladesh, were tested for the presence of adenoviruses by using an enzyme immunoassay (EIA). EIA-positive stool samples were serotyped with monoclonal antibodies specific for adenovirus type 40 (Ad40) and Ad41 and group antigen, inoculated into Graham G293 cells, and retested by EIA. Of adenovirus-positive cultures, 125 (2.8%) specimens were confirmed as enteric adenoviruses (EAds), of which 51 (40.8%) were typed as Ad40 and 74 (59.2%) were typed as Ad41, and 12 of 4,409 (0.3%) were identified as nonenteric adenoviruses. A slight peak of incidence of EAd infection was observed in the cool, dry months, and an outbreak of Ad40 infections occurred in March 1988, when the detection rate of EAd reached 12.3%. Information on age, gender, and symptoms was available for 80 infants infected with adenovirus only. Age distribution was similar for types 40 and 41 and nonenteric adenovirus; the median ages were 11, 12, and 12 months, respectively. The ratio of males to females for the 80 infants varied according to serotype; Ad40 had the highest male/female ratio, 2.17. The symptoms experienced by the 80 children were similar for each adenovirus type. The most common clinical features of EAd infection were watery diarrhea (87.5%), more than eight loose bowel movements per day in the 24-h period prior to presentation (68.8%), with vomiting (80.0%), abdominal pain (76.3%), and low-grade fever (95.0%); these symptoms are significantly similar to symptoms of infants infected with group A rotavirus. EAd infection generally gave rise to mild to moderate dehydration, which is significantly similar to dehydration produced by infection with rotavirus.

A 5-week-old belgian colt was examined for colic of 12 hours duration after several episodes of diarrhea. Physical examination revealed signs of abdominal pain, mild dehydration and normal auscultable borborygmi in all abdominal quadrants. Distention of the cecum, large colon and small intestinal was evident on abdominal radiographs. The foal was treated medically as the owners declined surgery. The colt was euthanized because of continued deterioration and failure to respond to medical therapy. Post-mortem exam revealed the presence of a trichophytobezoar obstructing the distal part of the transverse colon.

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)

Oral antimicrobial substances belonging to the beta-lactams, quinolones, macrolides, tetracyclines and the trimethoprim-sulfamethoxazole combination are among the most prescribed classes of drugs in private practice. Knowledge of the potential side effects considered in the light of various patient-associated factors such as genetic makeup, renal and liver function, underlying diseases, drug allergies and coadministered drugs, is important in order to minimize the risk of adverse reactions. This article reviews important side effect patterns and focuses on more recent aspects of antibiotic-associated diarrhea and beta-lactam allergy relevant to the practicing physician. Diarrhea occurring during antibiotic treatment raises the possibility of Clostridium-difficile-associated disease, which may evolve into life-threatening toxic megacolon. Mild cases with resolving symptoms after discontinuation of the antibiotic usually do not require further workup. More severe cases with watery diarrhea, abdominal pain, dehydration and electrolyte abnormalities warrant rapid diagnosis, cessation of antibiotic treatment and specific treatment including oral metronidazole. The use of oral vancomycin as a first line drug is discouraged because of the possibility of selecting vancomycin-resistant enterococci. Hypersensitivity reactions to beta-lactams are the most important type of side effects which can often be prevented. Patients with a history of beta-lactam associated IgE-mediated hypersensitivity (hives, wheezing or hypotension) should undergo penicillin skin testing. The frequently observed maculopapular rash associated with aminopenicillins without hives is in most cases not caused by an IgE-mediated mechanism. Patients with previous life-threatening penicillin allergy such as anaphylaxis or Lyell's syndrome should not undergo skin testing. Currently available tests do not reliably predict cephalosporin hypersensitivity. More recent data suggest that crossreactivity between penicillins and cephalosporins is infrequent. It thus seems safe to administer a cephalosporin to a penicillin-allergic patient, though excluding patients with previous life-threatening penicillin reactions.

Cyclic vomiting syndrome (CVS) is an unusual cause of episodic emesis in children. It manifests as intermittent episodes of severe vomiting, similar in time of onset and duration, with no symptoms during the intervening period. Dehydration necessitating intravenous fluid therapy may occur. Most therapeutic maneuvers have proven unsuccessful. We report the use of erythromycin as a prokinetic agent in the treatment of cyclic vomiting in 24 children (10 boys, 14 girls). Many patients had mild associated abdominal pain with their vomiting. Fourteen patients had previously been given metoclopramide but none responded. Two patients were mildly developmentally delayed. Twenty-four patients were given oral erythromycin ethylsuccinate, approximately 20 mg/kg/day, in two to four divided doses for 7 days. This dose was repeated as needed when symptoms reappeared. Eighteen of 24 patients reported total resolution of symptoms when re-evaluated at 2 and 6 months. All males responded, eight of 18 responders were female, and all six with partial or no response to therapy were female. This uncontrolled trial suggests that erythromycin may be a useful prokinetic agent in the treatment of CVS in childhood. Because the study was uncontrolled, placebo effect cannot be excluded. Case-controlled, double-blinded prospective trials should be considered to evaluate the effectiveness of erythromycin in CVS.

A 12-year-old Quarter Horse gelding was admitted to the veterinary medical teaching hospital with a 2-day history of signs of abdominal pain. Initial findings on physical examination included signs of lethargy, dehydration, diarrhea, and gastric reflux. Results of laboratory testing indicated that the horse had panleukopenia with neutrophilic toxic changes, was dehydrated, and was hypocalcemic. During the first 48 hours of hospitalization, 1 abdominal palpation per rectum and 3 analyses of peritoneal fluid were performed; abnormalities were not detected. A preliminary diagnosis of enterocolitis was made. Salmonella anatum was isolated from the feces. The horse's condition improved during a 5-day period, although left jugular thrombosis did develop. On day 8 of hospitalization, the gelding was found dead. Necropsy revealed acute severe fibrinous peritonitis as the result of vasculitis and thrombosis of the caudal mesenteric artery and its cranial rectal branch with rectal infarction and perforation. Immediate classification of rectal tears and perforation as iatrogenic should be avoided. Ischemic vascular disease is a consideration, and horses with thromboembolic disorders may be at risk for rectal perforations.

The clinical and clinicopathologic characteristics of fatal necrotizing enterocolitis were examined in 16 horses (age 4 months to 12 years). At initial presentation, 8 of 16 horses were pyrexic (median temperature, 38.4 degrees C; range, 33.8 to 40.6 degrees C); all 16 were tachycardic (median heart rate, 93 bpm, range, 66 to 138 bpm); 13 of 16 were tachypneic (median heart rate, 36 bpm, range, 16 to 80 bpm), dehydrated, and had discolored mucous membranes. All horses that were pyrexic were also tachycardic and tachypneic. PCV was high (> 45%) in 14 horses. Six horses were leukopenic (< 5,000 cells/microL); 12 were neutropenic (< 2,300 cells/microL), and 14 had > 100 band neutrophils/microL. Twelve horses were acidemic (pH < 7.37; range, 6.88 to 7.33) and the venous bicarbonate concentration was low (< 23 mEq/L) in 14 horses. Median anion gap in 16 horses was 31.5 mEq/L (> 15 mEq/L in 15 horses). Eleven of 16 horses were hyponatremic (< 137 mEq/L), 1 horse was hypernatremic (> 143 mEq/L), 3 were hypokalemic (< 3.2 mEq/L), 6 were hyperkalemic (> 4.5 mEq/L), and 14 were hypochloremic (< 98 mEq/L). Serum creatinine concentrations were high (> 1.4 mg/dL) in 15 horses. Abdominal fluid was examined in 12 horses 4 had total protein concentrations > 2.5 g/dL and 6 had nucleated cell counts > 5,000/ microL and < 10,000/microL; none had > 10,000/microL. Eight of 12 samples revealed a nondegenerate neutrophilia (> 50%). Abdominal fluid collected from 4 horses immediately before death was normal in 2 horses and indicative of suppurative inflammation in 2. All 8 horses tested had low or nonexistent serum immunofluorescent antibody titers to Ehrlichia risticii. Four of 16 horses had Salmonella spp isolated from feces or tissues. All 16 horses either died (5 of 16; 31%) or were euthanized because of a grave prognosis. Median time to death was 45.5 hours (range, 7 to 113 hours) from the time of admission. Death was preceded by severe abdominal pain in 14 horses. Fatal necrotizing enterocolitis of horses is characterized by a brief course, profound dehydration, electrolyte derangements, acid-base abnormalities, and terminally, severe abdominal pain. Abdominal fluid analysis was frequently not indicative of the severity of disease.

Pseudomembranous colitis is an inflammatory disease of rectal and colonic mucosa caused by Clostridium difficile produced toxin. The inflammation is produced as the consequence of a non-specific response to several agents. It usually presents with abdominal pain and mild watery diarrhea which used to decrease when removing the antibiotic or when starting the therapy with metronidazole or vancomycin. In aged patients, with severe concomitant diseases, may appear complications such as dehydration, electrolyte imbalance, hypotension and toxic megacolon, which occasionally may lead to fatal outcome. We report the case of a severe pseudomembranous colitis, with a fulminant clinical course, in a patient without a recent antibiotic therapy.

A 67 year-old woman in steady-state treatment with clozapine 150 mg/24 h was co-medicated with 100 mg/24 h of fluvoxamine. During the next months the patient suffered from nausea and occasionally vomited, but these symptoms were ascribed to fluvoxamine, and as she mentally improved, both treatments were continued. Two months after the start of fluvoxamine her serum clozapine concentration was 7570 nmol/l or 7.5 fold higher than before fluvoxamine was added. The woman was admitted to hospital, suffering from abdominal pain, dehydration and fever (38.5 degrees C). Serum creatinine concentration was increased, but normalized during hydration. After 18 days care the woman felt well and was discharged from hospital. The case report shows that certain combinations of selective serotonin reuptake inhibitors and neuroleptic drugs should either be avoided or the serum concentrations of the drugs closely followed.
