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.

Physical exercise is probably both beneficial and harmful for the gastrointestinal tract, depending partly on the training intensity. On the one hand, gastrointestinal symptoms such as heartburn, chest pain, nausea, vomiting, abdominal cramps, side ache and diarrhoea are common during heavy exercise. On the other hand, physical activity seems to protect from colon cancer, cholelithiasis and diverticular disease. Constipation has been shown to be related to inactivity. Despite this, no overwhelming evidence exists for a positive effect of physical exercise as a treatment option for chronic constipation. The reasons behind these somewhat discrepant effects are not understood fully. Altered gastrointestinal blood flow, effects on gastrointestinal motor function, neuroendocrine changes and mechanical effects are probably involved. Conflicting results exist regarding the effects of physical activity on gastrointestinal motility. Modern technologies now make motility studies in various parts of the gastrointestinal tract possible. More studies are needed to understand better the effects of physical exercise on the gastrointestinal tract. In particular, the relationship between the training intensity and duration and positive and negative alterations in gastrointestinal physiology needs to be addressed further.

Valproic acid is a widely used drug in the treatment of epilepsy and, compared to other anticonvulsant drugs, is considered safe. The most common side effects of valproic acid ingestion or therapy are transient nausea, vomiting, abdominal cramps, and diarrhea. Most of these complaints are mild. However, more serious adverse reactions can occur such as hepatotoxicity and pancreatitis. It has been proposed that, whenever possible, valproic acid not be used in the younger child, the child with a severe seizure disorder or other neurological disorders, mental retardation, developmental delay, organic brain disease, congenital abnormalities, or the child who is taking multiple anticonvulsant drugs, as these factors may increase the likelihood of hepatotoxicity and/or pancreatitis. In the present report, we describe a fatal case of acute hemorrhagic pancreatitis in a four and a half-year-old Hispanic female child who was receiving valproic acid in combination with another anticonvulsant drug for control of focal seizures. The patient also received the macrolide antibiotic azithromycin. For pediatricians and forensic pathologists valproic acid-induced pancreatitis can be a challenging diagnosis which must not be mistaken for abdominal trauma. We discuss the workup of the patient and differential diagnosis.

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.

Opioid-induced sedation is a major complication in patients with cancer pain. This study assessed the effectiveness of donepezil in opioid-induced sedation and related symptoms in patients with cancer pain. Twenty-seven patients who were receiving strong opioids for pain and reported sedation were enrolled. Donepezil 5 mg was given every morning for 7 days. Changes between baseline and Day 7 in sedation, pain, fatigue and other symptoms were evaluated using the Edmonton Symptom Assessment Scale. Fatigue was also measured using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue). Overall usefulness of donepezil was measured by the patient at the end of the study. In 20 evaluable patients, sedation, fatigue, anxiety, well-being, depression, anorexia and problems with sleep were significantly improved. Side effects included nausea, vomiting, diarrhea, muscle and abdominal cramps, and anorexia. Overall, however, the treatment was well tolerated. Donepezil appears to improve sedation and fatigue in patients receiving opioids for cancer pain. Randomized controlled trials of this agent are justified.

Levamisole, an anthelmintic agent with a wide range of immunomodulatory actions, has been used successfully as monotherapy and an adjunct to treatment in a variety of diseases. Since 1990, combination therapy of levamisole and fluorouracil has played an important role in the treatment of resected Dukes stage C adenocarcinoma of the colon. Because of its immunomodulating effects levamisole has been used in a wide range of diseases with and without success. In dermatologic disease levamisole has been successfully used in the treatment of parasitic, viral and bacterial infections including leprosy, collagen vascular diseases, inflammatory skin diseases and children with impaired immune a variety of reasons. It has also been used in combination with other drugs for treating a number of dermatologic disorders, e.g. in combination with cimetidine for treating recalcitrant warts, with prednisolone for treating lichen planus, erythema multiforme and aphthous ulcers of the mouth. Adverse affects of levamisole are mild and infrequent and include rash, nausea, abdominal cramps, taste alteration, alopecia, arthralgia, and a flu-like syndrome. It can rarely cause agranulocytosis. More studies need to be undertaken to study the full potential of levamisole in dermatologic diseases.

On May 6, 1998, the Olmsted County Public Health Department initiated an investigation into an outbreak of diarrheal illness that had occurred among people who swam frequently at a local swimming pool. Interviews of swimmers and microbiological testing of stool samples and swimming pool filter material were conducted to determine the source of the outbreak. Twenty-six of 206 swimmers interviewed had illnesses that met the case definition. The most common symptoms were diarrhea (100 percent), abdominal cramps (81 percent), and nausea (77 percent). The median duration of symptoms was nine days. Four cases of cryptosporidiosis were confirmed by stool analysis. The outbreak was found to be associated with swimming at the pool. Public awareness-including an understanding that recreational water facilities should be avoided during diarrheal illness-and proper pool hygiene are vital in preventing cryptosporidiosis outbreaks. Health care providers also must consider testing specifically for cryptosporidiosis when a patient presents with persistent diarrhea.

Trials have provided conflicting estimates of the risk of gastrointestinal illness attributable to tap water. To estimate this risk in an Iowa community with a well-run water utility with microbiologically challenged source water, the authors of this 2000-2002 study randomly assigned blinded volunteers to use externally identical devices (active device: 227 households with 646 persons; sham device: 229 households with 650 persons) for 6 months (cycle A). Each group then switched to the opposite device for 6 months (cycle B). The active device contained a 1-microm absolute ceramic filter and used ultraviolet light. Episodes of "highly credible gastrointestinal illness," a published measure of diarrhea, nausea, vomiting, and abdominal cramps, were recorded. Water usage was recorded with personal diaries and an electronic totalizer. The numbers of episodes in cycle A among the active and sham device groups were 707 and 672, respectively; in cycle B, the numbers of episodes were 516 and 476, respectively. In a log-linear generalized estimating equations model using intention-to-treat analysis, the relative rate of highly credible gastrointestinal illness (sham vs. active) for the entire trial was 0.98 (95% confidence interval: 0.86, 1.10). No reduction in gastrointestinal illness was detected after in-home use of a device designed to be highly effective in removing microorganisms from water.

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.

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.
