A variety of drugs and toxins can produce severe abdominal pain and, in some cases, a surgical abdomen. Toxins can be classified according to mechanisms of injury: 1. Corrosives often produce severe gastroenteritis and may result in gastric or esophageal perforations. Examples of corrosive substances include aspirin, iron, mercury, acids and alkali. 2. Drugs may cause intestinal ileus or obstruction by pharmacologic actions (i.e., anticholinergic drugs and narcotics) or by mechanical obstruction (charcoal and drug bezoars). 3. Abdominal pain simulating an acute abdomen may result from systemic effects of black widow spider envenomation or intoxication with heavy metals such as lead and arsenic. 4. Ischemic bowel disease may occur from use of vasoconstrictor drugs, such as ergotamines, amphetamines and cocaine, or may follow treatment with catecholamines or digitalis in critically ill patients. Small bowel ischemia is life-threatening and may require bowel resection. 5. Many drugs cause abdominal pain by directly injuring abdominal organs, such as the liver and pancreas. Antibiotic-associated colitis may present with abdominal pain and inflammatory diarrhea. Consideration of drugs and toxins plays an important role in the differential diagnosis of the acute abdomen.

Antibiotic-associated colitis is known to occur with temporal and geographic clustering. During 1979 a marked increase in the incidence of this disease was noted at our institutions. The clinical, epidemiological, and endoscopic features are reported. Typical features included the acute onset of watery diarrhea, fever, abdominal pain, tenderness, and the presence of leukocytosis. Epidemiological data revealed a nosocomial pattern of this illness and a striking female predominance. Two-thirds of the patients had an underlying gynecological or urological disorder. Dysuria and sterile pyuria were unexpected findings. It is suggested that the organism responsible for this disease may be hospital acquired and associated with underlying genitourinary disorders.

We describe a case of bacteremia due to Clostridium difficile, which was successfully treated by intravenous vancomycin. A 69-year-old woman was admitted to our hospital because of third degree burn injuries. She was treated with cefazolin for two weeks followed with flomoxef for one week before the operation (debridement and grafting of skin). On the third postoperative day high fever (temperature 40 degrees C), abdominal pain and severe watery diarrhea developed. Antibiotic-associated colitis with bacteremia was diagnosed presumptively, flomoxef was stopped, and oral and intravenous therapy with vancomycin was started. A blood culture taken before the administration of vancomycin yielded C. difficile accompanied with Enterococcus faecalis and Enetrococcus casseliflavus. A stool culture taken on the next day yielded C. difficile, and a stool latex agglutination test was also positive. The patient improved slowly. Parenteral vancomycin was discontinued after two weeks. One week later, the patient developed pneumonia, and imipenem/cilastatin was added. Soon after addition of the agent, she developed recurrent diarrhea despite continual oral vancomycin therapy. The fecal samples obtained at this time were positive for C. difficile by culture and positive for toxins A & B. She was satisfactorily treated with oral vancomycin for a total of four weeks. After the following two weeks, however, recurrence of diarrhea developed again, which rapidly decreased with oral vancomycin for seven days. The patient did well thereafter and was discharged. All three C. difficile isolates from blood and fecal specimens were positive for toxins A & B, and identified the same PCR ribotyping pattern.

Antibiotic-associated colitis is a gastrointestinal complication of antibiotic use commonly seen in hospitalised patients, with Clostridium difficile (C. difficile) colitis being the most common type. We present a case of haemorrhagic colitis secondary to Klebsiella oxytoca following self-initiated amoxicillin-clavulanic acid use. An 85-year-old woman presented to the emergency department with abdominal pain and mucobloody diarrhoea. History was notable for an ongoing 5-day course of amoxicillin-clavulanic acid use. The CT scan of her abdomen revealed extensive diffuse thickening of the ascending and transverse colon. Stool culture grew K. oxytoca, an established cause of haemorrhagic colitis. She declined colonoscopy but recovered with withdrawal of all antibiotics and conservative treatment. We should be vigilant to haemorrhagic colitis following antibiotic use which is not always C. difficile related.
