To further understand the pathophysiology of arterial diseases induced by oral contraceptives (OCs), a case report is presented of a young woman who died of extensive visceral artery thrombosis. The possible role of estrogens and progestogens and of cigarette smoking as the predisposing factors in this patient are discussed. A 26-year-old woman, who complained of progressive abdominal pain and whose past medical and surgical history was negative, was admitted to the general surgery service. She was the mother of 1 child and had had 2 previous spontaneous abortions. She had received ethinyl estradiol 35 mcg with norethindrone 500 mcg and 1000 mcg for 3 months, but because of a problem with breakthrough bleeding the medication was changed to mestranol 50 mcg with norethindrone 1000 mcg. She had been taking Ortho-Novum 1/50 for 2 1/2 years. She had smoked 25-35 cigarettes daily for about 10 years but denied use of alcohol or other drugs. She was not known to be diabetic, hypertensive, or dyslipidemic, and had no history of atherosclerosis in her family. For 7 months prior to her admission, the patient complained of abdominal pain, which progressively increased in intensity and duration, interrupted by periods of well-being. The patient reported 2 recent, isolated episodes of mild proctalgia but no tenesmus or melena. There had been no fever, but the patient had been anorexic for the past 2 weeks and reported losing 10 kg in the past month. She had no complaints apart from those related to the gastrointestinal system. At an emergency laparotomy, gangrenous acalculous cholecystitis and infarction of the terminal ileum were discovered. A cholecystectomy with resection of the terminal ileum and the right colon was performed. An end-to-end primary anastomosis was performed. On exploration of the superior mesenteric artery, a thrombus was discovered at its origin. As a transverse arteriotomy showed a good retrograde flow, a thrombectomy was performed. There appeared to be an unsatisfactory antegrade flow. The superior mesenteric artery then was transposed in an end-to-end fashion on the abdominal aorta. An immediate postoperative arteriogram showed thrombosis of the celiac axis at its origin. Revascularization failed to improve the condition of the intestine. The patient died. The intent of this case report is to emphasize that the association between smoking and oral contraceptives can cause cardiovascular disease in young women, and a failure to recognize this association can result in delayed diagnosis and worsen the prognosis.

Multi-drug resistant Shigella dysenteriae type 1 caused an epidemic of dysentery in a village in southern India. The epidemic started as a common source outbreak, through the piped water supply of the village with subsequent person-to-person spread. Although the attack rate was high, with nearly 1/2 the children under age 5 being affected, the case fatality rate was only about 1%. Of the 248 patients who attended the field clinic, 89.4% passed small mucoid stools mixed with blood, with the majority complaining of crampy lower abdominal pain and tenesmus. The other 10.6% had a history of diarrhea, only without blood and mucus. Moreover, 126 patients were given appropriate doses of sulphamezathine for 4-7 days. Adequate doses of neomycin were also given as therapeutic agent to infected individuals. The role of early maintenance of hydration and nutrition in the field situation in managing diarrheal epidemics is emphasized. Comparisons with mortality figures in other epidemics support the hypothesis that early and adequate maintenance of hydration and nutrition is a significant factor in reducing mortality.

Following a nationwide outbreak of Shigella dysentery type 1 and the recognition of Shigella isolates resistant to ampicillin, the drug of choice, we conducted a clinical trial to compare the efficacy of ampicillin v. trimethoprim-sulphamethoxazole for the treatment of Shigella dysentery. Patients with symptoms of dysentery and no other complicating illness were randomized into one of two treatment groups. Patients in the two groups were comparable at the time of hospital admission with regard to age, sex, presenting complaints and Shigella strains. They responded well with both regimens and there was no significant difference in the mean time until stool became culture negative (1.4 days), temperatures returned to normal (2.7 days) and faecal leucocytes disappeared (3.0 days); abdominal pain, tenesmus and stool blood and mucus improved significantly more rapidly with trimethoprim-sulphamethoxazole than with ampicillin. There was no evidence of toxicity with either drug. While both drugs are effective for the treatment of Shigella dysentery, trimethoprim-sulphamethoxazole was considered to be superior.

During a 15-month study, 8097 fecal specimens submitted to clinical microbiology laboratories at eight hospitals in different parts of the United States were examined. Campylobacter jejuni was isolated from 4.6%, Salmonella from 2.3%, and Shigella from 1.0%. Isolation rates for each pathogen were highest from stool specimens that were watery, bloody, or contained leukocytes. The peak isolation rate for C. jejuni was in persons ages 10 to 29 years; for Salmonella, in children younger than age 10 years; and for Shigella, in children ages 5 to 9 years. The clinical features of the three infections were nearly identical. In contrast, abdominal pain, bloody diarrhea, fever, tenesmus, and abnormal sigmoidoscopy findings were present significantly more often in patients infected with C. jejuni than in a control group of patients with diarrhea. Of patients with leukocytes in their stools and a history of fever, 45.9% were infected with one of the three pathogens. Use of laboratory and clinical findings defined groups with high or low risk of these three infections but could not accurately predict isolation. Fecal cultures had the highest yields when obtained from patients within 7 days from the onset of symptoms.

The authors report a case of giant diverticulum of the sigmoid colon, a very rare complication of diverticulosis of the colon, since only 38 cases have been reported in the literature. The diverticulum was seen at barium enema in a 66-year-old man complaining of digestive symptoms consisting of lower abdominal pain, tenesmus, diarrhea and fever. Segmental resection of the sigmoid colon including the site of implantation of the diverticulum with end-to-end anastomosis at the same operative stage led to definitive cure. On the basis of a study of the literature, the authors define the clinical, diagnostic and pathogenic characteristics of the condition.

In Eseka and Edea bilharziasis caused by S. intercalatum is transmitted by B. forskali, the only intermediate host of human schistosomes found in the area. The prevalence of the disease is obtained by calculating the percentage of inhabitants voiding eggs in their stools in the districts of the towns located in the neighbourhood of Bulinus-containing streams and ponds. The prevalence is low, 5,6% in Eseka and 4,9% in Edea. The size and the number of waterbodies where transmission occurs is small. Rectoscopy showed that rectal and sigmoid lesions are frequently seen. Clinical manifestations are abdominal pain, diarrhoea, dysentery, tenesmus, appearance of blood in the stools. Hepatomegaly and splenomegaly occur sometimes. A single dose of 2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a] isoquinolin-4-one (praziquantel, EMBAY 8440, Biltricide) is effective in the treatment of the disease.

Adequate measures of diarrheal disease are important to assess severity for clinical use and outcomes research. We developed a questionnaire to assess diarrhea severity and complications, and administered it to 205 HIV positive patients with diarrhea, fever, or weight loss. Noteworthy variations in stool form were reported by individuals and across subjects. Self-reported diarrhea correlated with the occurrence of any stool pictured without form. However, verbal descriptors "loose" and "semiformed" had little value in assessment of diarrheal disease. Both verbal and pictorial stool descriptors correlated well with diarrhea complications (pain, urgency, tenesmus, incontinence, and nocturnal diarrhea). By factor analysis, discomfort and nondiscomfort diarrhea complications loaded on different factors, consistent with clinical experience that discomfort is a distinct problem in diarrheal disease. In summary we have developed an instrument to precisely characterize diarrhea severity that correlates well with clinically important events such as incontinence and abdominal pain.

The study was undertaken to identify the presenting features of intestinal endometriosis and to evaluate its investigation and surgical management. Twenty-six cases of intestinal endometriosis were identified during a fourteen year period. The commonest site of occurrence was the rectosigmoid region (11 cases) followed by the appendix (9 cases), and ileocaecal region (6 cases). Abdominal pain was the main presenting feature in 20 cases, with associated nausea and vomiting in 12 cases and altered bowel habit in ten. Other presenting features included rectal bleeding, abdominal bloating and tenesmus. Endometriosis was not suspected preoperatively in any of the patients without a past history of this condition. Accurate preoperative diagnosis proved very difficult, with only laparoscopy providing definite evidence of intestinal endometriosis prior to formal surgery. Colonic resections were performed in 12 cases, small bowel resection in six cases and appendicectomy in nine cases, together with resection of adjacent adherent structures. This series illustrates the difficulty of establishing an accurate preoperative diagnosis, and the propensity of intestinal endometriosis to mimic other gastrointestinal diseases, particularly carcinoma and inflammatory bowel disease.

Of 230 cases of bloody diarrhoea studied, 100 (43.5%) were positive for Shigellae by stool culture, of which Shigella dysenteriae type 1 was isolated from 56 cases, S. flexneri from 35, S. boydii from 5 and S. sonnei from 4. The major clinical manifestations of the patients infected with Shigella spp. were abdominal pain, anorexia, vomiting, tenesmus, and fever. Fever of above 100.5 degrees F and frequency of stool of more than 15 per day were noticed more among cases infected with S. dysenteriae type 1 and S. flexneri. Vomiting was more frequently observed in cases infected with S. sonnei or S. boydii (44.4%) as compared to those infected with S. dysenteriae type 1 (10.7%) and S. flexneri (8.6%). All Shigella isolates were uniformly susceptible to norfloxacin and ciprofloxacin but were resistant to streptomycin. S. dysenteriae type 1 isolates were susceptible to nalidixic acid (69.6%), ampicillin (5.4%), TMP-SMX (12.5%), furazolidone (98.2%) and gentamycin (80.4%), whereas all other Shigella isolates (S. flexneri, S. boydii, and S. sonnei) were uniformly susceptible to nalidixic acid, > 94% susceptible to furazolidone, and only moderately susceptible to ampicillin (28.6% to 55.5%) and TMP-SMX (22.2% to 48.6%).

Diarrhea continues to be a major cause of mortality and morbidity in third world countries as well as a major symptomatic complaint in the primary care setting in the United States. The etiologic pathogen depends on an exposure history to include recent travel to foreign countries, consuming fecally contaminated water or food, prior use of antibiotics, or homosexual behavior. A careful history from patients directed at attempting to identify particular risk factors may help in making a diagnosis. Not all patients require a diagnostic workup. A large number of patients may only require oral rehydration, careful observation over time with or without use of antimotility agents. In toxic appearing patients or patients with fever, however, bloody stools, abdominal pain or tenesmus, a selective diagnostic workup is indicated. Antimicrobial treatments are not always required, some pathogens clearly call for treatment while some have less clear indications and other pathogens are not responsive to antimicrobial agents at all. Finally, one needs to remember that the differential diagnosis of acute diarrhea includes many noninfectious origins.
