Six patients with severe and complicated falciparum malaria (6.7 +/- 2.7 WHO criteria) were admitted to our Intensive Care Unit. All patients acquired the disease while travelling in tropical Africa without appropriate chemoprophylaxis. The clinical manifestations included hyperpyrexia (all patients), chills (4), sweating (2), asthenia (3), anorexia (2), headache (1), arthralgias (1), vomiting (4), diarrhoea or abdominal discomfort (3), jaundice (2) and disturbances of consciousness (4). All patients had anemia, thrombocytopenia, hyponatremia, hypoproteinemia, hypoalbuminemia, hypocalcemia and acute renal failure, in one case associated with anuria. A low grade parasitemia was observed in two patients and a high grade parasitemia (20%-58% of erythrocytes) in four. Exchange transfusion was performed only in high parasitemic patients and all of them survived. All patients were treated with quinine, a sulfonamide and pyrimethamine. Additionally, five patients received oxytetracycline, doxycycline or clindamycin. Three patients required hemodyalisis. Five patients had delirium, coma or seizures. All patients had at least one sign of hepatic impairment: liver enlargement, jaundice or increased bilirubin or aminotransferase levels. Two patients had spleen enlargement. Laboratory findings suggested disseminated intravascular coagulation in four patients. Four patients developed pulmonary changes and three of them required mechanical ventilation. A Swan-Ganz catheter was placed in four patients. In three of them (two with pulmonary edema) the pulmonary capillary wedge pressure was initially increased, which suggested a cardiogenic or hypervolemia mechanism, but soon returned to normal level. One patient with low grade parasitemia died because of adult respiratory distress syndrome after 18 days. In our series, the degree of parasitemia was not related to the severity of the disease.

Here we report an unusual case of T-cell lymphoma presenting as ascites. A 49-yr-old woman was admitted to the hospital for abdominal discomfort associated with increasing abdominal girth over the course of 3 mo. She also complained of nausea, vomiting, and diarrhea. On physical examination, a tense and distended abdomen and edema of the lower extremities were noted. Neither hepatosplenomegaly nor lymphadenopathy was found. A CT scan of the abdomen and pelvis showed a large abdominal/pelvic mass surrounding the small bowel and omentum and small nodes in the para-aortic and mesenteric regions. The cytospin prepared from the peritoneal fluid was hypercellular and composed of a population of monotonous, noncohesive cells with a high nuclear/cytoplasmic ratio and a single prominent central nucleolus. The cells were positive for leukocyte common antigen and Leu-22 (CD43) but negative for keratin, L26, UCHL-1, kappa, lambda, CD3, Ki-1 (CD30), S-100, and carcinoembryonic antigen. Morphologic and immunologic findings were suggestive of T-cell immunoblastic lymphoma. Peripheral T-cell lymphomas rarely present as ascites; this case demonstrates the value of effusion cytology in making this diagnosis.

A case of human infection with Heterophyes nocens (Heterophyidae) was incidentally found in a biopsy specimen of the Meckel's diverticulum at the upper part of the small intestine. The patient was a 58-year-old man living in a rural area of Talsonggun, Kyongsangbuk-do. He had gastrointestinal symptoms such as epigastric pain, indigestion, and abdominal discomfort for 3 months, and severe diarrhea, abdominal pain, and vomiting for about 1 month before hospitalization. Endoscopy of the upper part of the small intestine revealed a Meckel's diverticulum, and it was excised and histopathologically examined. Three adult flukes were incidentally found sectioned in the mucosa, and they were identified as H. nocens. The patient had a history of eating raw mullets at a fish market in Pusan 6 months ago, and the mullets were presumed to be the source of infection. This case brings a considerable interest in that specific diagnosis of heterophyid infections could be done by sectional morphology of the worms.

On September 28, 1999, a previously healthy 48-year-old man from California sought care at a local emergency department (ED) and was hospitalized with a 2-day history of fever (102 F [38.9 C]), chills, headache, photophobia, diffuse myalgias, joint pains, nausea, vomiting, constipation, upper abdominal discomfort, and general weakness. On September 26, he had returned from a 10-day trip to Venezuela. On September 29, an infectious disease physician from the ED contacted the Marin County Health Department (MCHD) about the patient's symptoms; MCHD reported his illness to the California Department of Health Services (CDHS) as a suspected case of viral hemorrhagic fever. This report describes the investigation of the case.

Recently, the concept of gastric hypersensitivity was introduced as an important factor in the pathophysiology of functional dyspepsia (FD), but it is unclear which symptoms can predict the presence of gastric hypersensitivity. Therefore, we evaluated the relationship between common symptoms of FD and various parameters measured by gastric barostat in FD patients. Gastric barostat tests were performed in 64 FD patients and 20 healthy control subjects without gastrointestinal symptoms. Individual symptoms such as early satiety, postprandial fullness, sense of delayed emptying, nausea, vomiting, and epigastric soreness were collected and graded as mild to severe. Basal tone, gastric compliance, and postprandial receptive relaxation were similar in controls and patients, the threshold of abdominal discomfort was lower in FD patients than in controls (8.9 +/- 3.6 mm Hg and 14.5 +/- 3.7 mm Hg, respectively, P < 0.05). However, there were no significant differences in the threshold of abdominal discomfort according to the severity of individual symptoms. In conclusion, a simple evaluation of individual symptoms could not predict the presence of gastric hypersensitivity.

Gastric emptying scintigraphy (GES) is usually performed for up to 2 hr to measure the gastric emptying (GE) of solids. Symptomatic patients, however, may have borderline results at 2 hr, making it difficult to determine whether a gastric motor disorder is present. The aim of this study was to assess whether extending GES to 4 hr is useful in evaluating patients for gastroparesis and to correlate the results of GES with patient symptoms. We studied 129 patients undergoing GES at Temple University Hospital between July 1998 and March 1999. Solid-phase GE was measured at 0, 0.5, 1, 2, 3, and 4 hr after ingestion of a 99mTc sulfur colloid-labeled egg meal. Dyspeptic symptoms of upper abdominal discomfort, early satiety, postprandial abdominal bloating, nausea, vomiting, and anorexia were graded as none, mild, moderate and severe (0, 1, 2 and 3, respectively) with the sum representing a total symptom score. Of 129 patients, 86 had normal GE at 2 hr; 26 of the 86 normal scans at 2 hr were delayed at 3 hr. Six of the 60 scans normal at 2 and 3 hr were delayed at 4 hr. Of 43 patients with delayed GE at 2 hr, 39 were delayed at 3 hr and 35 were delayed at 4 hr. Overall, the percentage of patients with delayed GE increased from 33% at 2 hr only to 58% using the results of the 2-, 3-, and 4-hr scans (P < 0.05). There was a significantly greater symptom score in patients with delayed GE compared to patients with normal GE (8.4 +/- 0.5 vs 7.1 +/- 0.5; P < 0.05). Conclusion, prolonging GES after ingestion of a 99mTc-labeled egg meal from 2 to 4 hr increased the number of symptomatic patients found to have delayed GE. These results suggest that GES should be performed for up to 4 hrs when the 2-hr result is normal.

Gastroenterologists frequently encounter patients who report vague epigastric discomforts or sensations of fullness, bloating, and distention in the upper abdomen. The discomfort is neither burning in character nor severe in intensity; there is no nocturnal pain. The epigastric location of discomfort and lack of radiation may help to exclude biliary tract and pancreatic diseases. Nausea may be present, but there is little or no vomiting. After these patients ingest liquids or solid foods, the symptoms of easy filling or early satiety and increasing discomfort and nausea are almost always present. The patient may only report "indigestion," but a specific chief complaint, such as pain, discomfort, nausea, or bloating may be elicited with further inquiries. Solid foods usually provoke more symptoms than do liquids. Symptoms of early satiety, nausea, bloating, and abdominal discomfort may culminate in the vomiting of undigested food. These vague upper gastrointestinal (GI) symptoms have been termed "dyspepsia." When peptic diseases of the stomach are excluded, the symptom complex has been called "nonulcer" dyspepsia, a vague syndrome with symptoms attributed to stomach dysfunction. Nonulcer dyspepsia has been reviewed recently. Such symptoms, commonly attributed to a "functional" disorder, are very common in clinical practice, with an incidence of 30% of patients. In this review, we will discuss an approach to the evaluation and treatment of patients with symptoms of nausea, early satiety, bloating, and vague epigastric discomfort--dyspeptic symptoms associated with functional stomach disorders. We will review the anatomy and motility of the stomach and suggest potential neuromuscular malfunctions of the stomach that may result in epigastric symptoms. The potential role of stress and other brain-gut interactions, which may underlie these symptoms, will also be reviewed.

Gastrointestinal (GI) Adverse Drug Reactions (ADRs) from the NSAIDs are a major cause of morbidity and mortality in arthritic patients taking these drugs. The recent much heralded development of COX-2 selective drugs (celecoxib, rofecoxib), the objective of which has been to spare inhibition of the production of COX-1 derived mucosal protective prostaglandins, may have represented an advance in reducing the risk of serious ADRs--ulcers and bleeding--but does not appear to have reduced the incidence of symptomatic side-effects (nausea, vomiting, epigastric pain/heartburn, abdominal discomfort) which are a major reason for withdrawal from NSAID therapy, especially in the long term. The rationale of COX-2 selectivity from these newer drugs is controversial since there may be pharmacokinetic differences from established carboxylate-NSAIDs that accounts for their apparent lower ulcerogenicity. Moreover, concerns have been recently expressed that as COX-2 is important in ulcer healing, control of prostacyclin production and renal function that they may have adverse reactions from these effects. Indeed, recent reports of enhanced risk of congestive heart failure with rofecoxib are of importance and may relate to impaired prostacyclin production. Moreover, there are other therapeutic strategies that have yielded equally low ulcerogenic NSAIDs (e.g. the prodrug, nabumetone; the established COX-2 inhibitory drug, nimesulide) and even the well-established NSAIDs ibuprofen and diclofenac have relatively low upper GI ulcerogenicity and have been used as benchmark standards in comparative trials of the newer "Oxib" drugs (celecoxib, rofecoxib). Much research interest has centred on the nitric oxide-donating NSAIDs (NO-NSAIDs). The rationale for donating NSAIDs being to counteract the vasoconstriction effects of NSAIDs but this has yet to be fully evaluated. It is not certain that this "antidote" approach will be acceptable as there may also be systemic effects of the nitrobutoxyl--or other NO-donors that may have toxicological consequences. Another strategy is the development of mixed COX-5 lipoxygenase (LOX) inhibitors--the progenitors of which were benoxaprofen and BW-755C. The rationale of reducing the potential for lipoxygenase mediated actions in the stomach (e.g. vasoconstriction, leucocyte accumulation). Clearly, the need to develop newer NSAIDs with lower risks of ulcers and bleeding as well as symptomatic ADRs is still representing a major challenge.

An 11-year-old crossbred dog was presented with a history of episodic vomiting, diarrhoea, abdominal discomfort and coughing. These signs had been present for several years. Marked peripheral eosinophilia (10.3 x 10(9)/L) was found. No underlying cause of reactive eosinophilia was apparent. Bone marrow aspiration biopsy showed hyperplasia of the eosinophilic cell line, with some increase in immaturity, although all cells were morphologically normal. There were numerous eosinophils in bronchial wash fluid and eosinophilic infiltrates were evident in biopsies of pancreas, liver, small intestine and colon but not stomach. Hypereosinophilic syndrome was diagnosed. The dog responded well to twice daily treatment with hydroxyurea and prednisolone. Clinical signs are well-controlled 16 months later.

Impaired gastrointestinal motility as a result of interruption of sympathetic outflow is a common occurrence in the spinal cord injury (SCI) population. In addition, frequent use of medications with anticholinergic properties in this population results in further impairment of peristalsis resulting in gastrointestinal stasis. Since SCI patients often lack sensation below the level of injury, they may present with vague symptoms, which complicates the diagnosis of intestinal obstruction. We report the first case of gastric phytobezoar in a patient with T4 ASIA A paraplegia who presented with vague upper abdominal discomfort, anorexia, weight loss, and vomiting. Because mortality rates can be as high as 30% if phytobezoars remain untreated, gastrointestinal phytobezoars should be considered in the differential diagnosis of abdominal discomfort in SCI patients. Etiologic factors for phytobezoars are discussed for the general population and in particular, for patients with SCI.
