The National Association of People with AIDS (NAPWA) released a May 2, 1996, report stating that the tap water in the nation's major cities places people with weakened immune systems at risk for contracting cryptosporidium. Cryptosporidium is a potentially life-threatening microscopic parasite. In people with compromised immune systems, the symptoms of diarrhea, headache, abdominal cramps, nausea, vomiting, and fever can persist for months and lead to death. Twenty-two of the thirty-one cities surveyed had no testing or notification policies in place to reduce an outbreak of cryptosporidium. NAPWA recommends that people with HIV disease in extremely high-risk cities (Atlanta; Dallas; Minneapolis; Newark, NJ; St. Petersburg, FL; and Washington, DC) refrain from drinking tap water. Another 22 cities were found to be at high risk for an outbreak.

The efficacy of 1 mg 16,16-dimethyl-trans-Delta2 prostaglandin E1 (Gemeprost) pessaries in achieving cervical dilatation prior to intracavitary brachytherapy was investigated in 16 post-menopausal women with cervical carcinoma. All had received external beam pelvic radiotherapy in the preceding 6 weeks. Four patients were nulliparous and 12 multiparous (mean parity 1.9). FIGO stages were IB (2), IIA (4), IIB (5), IIIA (1), IIIB (3), IVB (1). The cervical os was assessed before pessary insertion and again at the time of intracavitary insertion. The os was closed in 100% (16/16) of patients before and open in 75% (12/16) of patients after pessary insertion. The maximum size of Hegar dilator passed without mechanical dila-tation was recorded. Mean cervical dilatation was 4.25 H (5.5 H in those with a clinical response). The 12 responding patients had rapid and uncomplicated procedures with no need for additional mechanical dilatation. Both patients in whom attempted mechanical dilatation failed had had previous conization of the cervix. The following mild side-effects were reported: abdominal cramps (43.8%), headache (12.5%) and fever (6.3%). These data support the use of Gemeprost pessaries to achieve cervical dilatation in post-menopausal women undergoing intracavitary brachy-therapy following external beam radiotherapy.

Salmon calcitonin (SCT) is a well-tolerated peptide drug with a wide therapeutic margin and is administered parenterally for long-term treatments of bone diseases. Its clinical usefulness would be enhanced by the development of an orally active formulation. In this randomized crossover double-blinded phase I trial, controlled by both a placebo and a parenteral verum, we have tested a new oral formulation of SCT associated with a caprylic acid derivative as carrier. Eight healthy volunteers received single doses of 400, 800, and 1200 microg of SCT orally, a placebo, and a 10-microg (50 IU) SCT intravenous infusion. SCT was reliably absorbed from the oral formulation, with an absolute bioavailability of 0.5-1.4%, depending on the dose. It induced a marked, dose-dependent drop in blood and urine C-terminal telopeptide of type I collagen (CTX), a sensitive and specific bone resorption marker, with the effects of 1200 microg exceeding those of 10 microg intravenously. It also decreased blood calcium and phosphate, and increased the circulating levels of parathyroid hormone (PTH) and, transiently, the urinary excretion of calcium. It was well-tolerated, with some subjects presenting mild and transient nausea, abdominal cramps, diarrheic stools, and headaches. This study shows that oral delivery of SCT is feasible with reproducible absorption and systemic biological efficacy. Such an oral formulation could facilitate the use of SCT in the treatment of osteoporosis and other bone diseases.

Some scientists added the progestin levonorgestrel to the vaginal ring which must be removed every 3 weeks to address the problem of irregular bleeding, but it adversely altered lipoprotein levels and caused too many hemorrhaging problems. On the other hand, scientists in the laboratory at Organon have conducted various studies of a vaginal ring with ethinyl estradiol and 3-keto-desogestrel at different doses which have yielded favorable results. A multicenter European study was conducted with 400 women aged 18-40 years wearing a vaginal ring with 0.120 mg keto-desogestrel and 0.015 mg ethinyl estradiol every day for 9 months. 10% had slight bleeding 15 days after insertion of the vaginal ring. In 10 women tested, the plasmal levels of progesterone and estrogen decreased by 4 nmol/l and 0.010 nmol/l, respectively. The first French study was conducted at the Gynecology College of Bordeaux and the South-West in 1988 and included 40 women followed for 9 cycles. The vaginal ring consisted of 2 compartments: the biggest compartment contained only 3-keto-desogestrel and the other also contained ethinyl estradiol. It remained in the vagina for 21 days, then was removed to be rinsed, dried, and placed in a box. It was reinserted on the 5th or 7th day of the cycle. This ring reduces the volume of blood during menses and eliminates abdominal cramps, nausea, and headaches. Women tolerate the vaginal ring better than they do oral contraceptives (OCs); for example, it does not cause them to gain weight, they tolerate glucose well, it brings about favorable changes in lipoproteins, it does not bring about conditions favorable to thrombophlebitis, and it can improve the skin for acne-sufferers. Young women accept vaginal rings enthusiastically. The efficacy of vaginal rings with 2 steroids is the same as that of OCs.

An outbreak of gastrointestinal illness occurred amongst attendees of a conference lunch in the Hunter area, New South Wales, in October 2001. A distinctive symptom reported by many ill persons was the presence of oily diarrhoea. The Hunter Public Health Unit investigated the outbreak by conducting a telephone interview of the cohort of conference attendees using a standard questionnaire. Twenty persons out of 44 attendees (46%) became ill following the conference. The median incubation period was 2.5 hours (range 1-90 hours). The most common symptoms reported were; diarrhoea (80%)-38 per cent of these reported oily diarrhoea; abdominal cramps (50%); nausea (45%); headache (35%) and vomiting (25%). For analyses, a case was defined as a person who developed oily diarrhea, or diarrhoea within 48 hours, or had at least two other symptoms of gastroenteritis within 6 hours, of the conference lunch. Seventeen persons had symptoms that met the case definition. None of the foods or beverages consumed were significantly associated with illness, however, all cases had consumed fish and none of those who did not eat fish (4 persons) became ill. Moreover, only 'fish' or 'potato chips' could explain a significant proportion of the illness. Analysis of the oil composition of the fish consumed was consistent with the known profile of the species marketed as 'escolar'. Among those who consumed fish the following potential risk factors did not have a significant association with the illness; Body Mass Index, age, health status and the amount of fish consumed. We concluded that consumption of fish within the marketing group escolar can cause severe abdominal cramping, nausea and vomiting, in addition to incontinent diarrhoea.

Scombroid fish poisoning is a clinical syndrome attributed to the ingestion of contaminated fish. A toxin or toxins, known as scombrotoxin, result from decomposition by endogenous flora of the amino acid histidine liberating bioactive amines, predominantly histamine. The presentation has features of histamine toxicity, typically with urticaria, flushing, headache, abdominal cramps, diarrhoea and vomiting. The course is usually mild and self-limiting. The author describes six cases of scombroid poisoning after ingestion of fish from the same Canberra restaurant. One case resulted in significant hypotension necessitating a prolonged stay in the ED.

Reovirus Type 2 was isolated from three patients aged 5, 9 and 10 years. The etiological role of Reovirus in one case was confirmed by demonstration of antibodies in convalescent serum and none in acute serum. Symptoms in this case were suggestive of infectious mononucleosis. In the second case, rhinitis and non-purulent otitis were preceded by two waves of fever, abdominal pain and emesis. Acute serum was not available but convalescent serum had a high titre to a Reovirus, thus supporting a Reovirus etiology. Symptoms in the third case were fever, intermittent headache, neck stiffness, abdominal cramps and weakness of a leg. Because of the unavailability of convalescent serum, evidence of a Reovirus etiology was incomplete. No attempt is made to associate Reovirus with a particular clinical picture. Rather, attention is simply drawn to the existence of Reovirus infections in Ontario.

From October 1997 through March 1998, three outbreaks of gastrointestinal illness among school children were linked to company A burritos. In September 1998, a similar outbreak occurred in three North Dakota schools following lunches that included company B burritos. We conducted an investigation to determine the source of the North Dakota outbreak, identify other similar outbreaks, characterize the illness, and gather evidence about the cause. The investigation included epidemiologic analyses, environmental investigation, and laboratory analyses. In North Dakota, a case was defined as nausea, headache, abdominal cramps, vomiting, or diarrhea after lunch on 16 September 1998. Case definitions varied in the other states. In North Dakota, 504 students and staff met the case definition; predominant symptoms were nausea (72%), headache (68%), abdominal cramps (54%), vomiting (24%), and diarrhea (16%). The median incubation period was 35 min and median duration of illness was 6 h. Eating burritos was significantly associated with illness (odds ratio, 2.6; 95% confidence interval, 1.6 to 4.2). We identified 16 outbreaks that occurred in seven states from October 1997 through October 1998, affecting more than 1,900 people who ate burritos from two unrelated companies. All tortillas were made with wheat flour, but the fillings differed, suggesting that tortillas contained the etiologic agent. Results of plant inspections, tracebacks, and laboratory investigations were unrevealing. More than two million pounds of burritos were recalled or held from distribution. The short incubation period, symptoms, and laboratory data suggest that these outbreaks were caused by an undetected toxin or an agent not previously associated with this clinical syndrome. Mass psychogenic illness is an unlikely explanation because of the large number of sites where outbreaks occurred over a short period, the similarity of symptoms, the common food item, the lack of publicity, and the link to only two companies. A network of laboratories that can rapidly identify known and screen for unknown agents in food is a critical part of protecting the food supply against natural and intentional contamination.

Scombroid poisoning is a form of toxicity caused by the ingestion of spoiled dark-flesh fishes, mainly of the scombroid family. The clinical picture is secondary to histamine toxicity, manifested as flushing, headache, palpitations, and abdominal cramps. The diagnosis is established on the basis of these typical clinical manifestations and fish-ingestion history. We report a case of a man with scombroid poisoning. He was diagnosed after presentation of two similar patients with the same epidemiological history.

Vibrio parahaemolyticus is a human pathogen that is widely distributed in the marine environments. This organism is frequently isolated from a variety of raw seafoods, particularly shellfish. Consumption of raw or undercooked seafood contaminated with V. parahaemolyticus may lead to development of acute gastroenteritis characterized by diarrhea, headache, vomiting, nausea, and abdominal cramps. This pathogen is a common cause of foodborne illnesses in many Asian countries, including China, Japan and Taiwan, and is recognized as the leading cause of human gastroenteritis associated with seafood consumption in the United States. This review gives an overview of V. parahaemolyticus food poisoning and provides information on recent development in methods for detecting V. parahaemolyticus and strategies for reducing risk of V. parahaemolyticus infections associated with seafood consumption.
