Between 1983 and 1988 we treated 36 patients with sporadic amyotrophic lateral sclerosis (ALS) by an array of antioxidants and added other drugs to the regimen whenever a patient reported deterioration. Our customary prescription sequence was N-acetylcysteine (NAC); vitamins C and E; N-acetylmethionine (NAM); and dithiothreitol (DTT) or its isomer dithioerythritol (DTE). Patients with a history of heavy exposure to metal were also given meso 2,3-dimercaptosuccinic acid (DMSA). NAC, NAM, DTT, and DTE were administered by subcutaneous injection or by mouth or by both routes, the other vitamins and DMSA by mouth alone. The hospital pharmacy supplied NAC and NAM injections fluid as 100 ml bottles of 5.0 and 5.85% solutions, respectively. DTT was delivered in special double-walled capsules of 200 mg. DTT/DTE injection fluid was added to the NAC and NAM bottles, the final DTT/DTE concentrations never exceeding 0.5%. DMSA was provided in 250 mg capsules. All of the 36 patients used NAC and DTT/DTE; 29 also used vitamins C and E; 21 also used NAM; and 7 also used DMSA, DMSA, NAM, vitamins C and E were tolerated well. In many patients, DTT, DTE, NAC and NAM induced pain, redness and swelling at the injection sites in that order of decreasing frequency. DTT and DTE did often and NAC did sometimes cause gastric pain, nausea and other abdominal discomfort. Comparison of survival in the treated group and in a cohort of untreated historical controls, disclosed a median survival of 3.4 years (95% confidence interval: 3.0-4.2) in the treated and of 2.8 (95% confidence interval 2.2-3.1) years in the control patients. This difference may be explained by self-selection of our highly motivated treated group and by its initial survival of diagnosis for an average of 8.5 months before onset of treatment. We conclude that antioxidants neither seem to harm ALS patients, nor do they seem to prolong survival.

The authors report a case of trichinosis acquired in Oklahoma City by an immigrant from Southeast Asia. The 49-year-old female reported having abdominal discomfort, nausea, and vomiting, and had purchased and eaten lightly cooked pork. She also complained of fatigue, anorexia, and muscle aches for several months. An immigrant from Laos, she stated that she regularly eats pork and prefers it rare or mildly cooked. The authors caution local physicians to be aware of the increased risk of trichinosis among Southeast Asian immigrants in the area, particularly those from Laos and Cambodia. Continued emphasis on the need to thoroughly cook all pork products is necessary if the incidence of trichinosis in the U.S. is to be controlled.

Hyperglycemia slows gastric emptying and increases the intensity of perception of gastric distension during fasting and small intestinal nutrient stimulation. In order to examine the possibility that abnormalities of gastric electrical rhythm may be associated with the effects of hyperglycemia, the gastric electrical rhythm (cutaneous electrogastrogram) and the perception rating scores for upper gastrointestinal sensations (visual analog scale) were examined. Studies were performed during intraduodenal triglyceride infusion in 10 healthy volunteers under euglycemic and hyperglycemic (approximately 15 mmol/liter) conditions. During fasting, hyperglycemia had no effect on either gastric electrical rhythm or sensation. Intraduodenal triglyceride infusion was associated with an increase in bradygastria (<2.4 cpm) during both euglycemia (33 +/- 9%) and hyperglycemia (36 +/- 10%, P < 0.05 vs baseline for each). During intraduodenal triglyceride infusion, tachygastria (>3.6 cpm) was more prevalent during hyperglycemia when compared to euglycemia (25 +/- 10% vs 1 +/- 1%, P < 0.05) and the perception rating scores for nausea and abdominal discomfort were greater during hyperglycemia (P < 0.05 for both). The intensity of nausea correlated with the proportion of time spent in tachygastria (r = 0.64, P < 0.01). These data are consistent with the concept that postprandial upper gastrointestinal symptoms in patients with diabetes mellitus may be modulated by the blood glucose concentration.

Pentoxifylline (POF) may suppress overproduction of tumor necrosis factor alpha (TNF alpha), which is thought to contribute to complications of human falciparum malaria. However, POF is believed to improve impaired capillary blood flow, which can be impaired in falciparum malaria. To test whether POF affects TNF alpha serum levels or other variables in this disease, we administered POF (20 mg/kg/day intravenously in 150 ml of saline for five days) randomized versus placebo (150 ml of saline without POF) in addition to standard antimalarial therapy. After recruitment of 51 patients with Plasmodium falciparum malaria, those receiving POF had more nausea and abdominal discomfort than the placebo group, as expected. Eleven of 27 patients receiving POF and three of 24 patients receiving placebo requested termination of the study medication (P < 0.05). Pentoxifylline did not change the decrease of TNF alpha levels or affect the clinical course in a significant way. Since POF failed to improve the clinical situation or to impact numerous laboratory parameters (including TNF alpha, thrombin-antithrombin III, thrombomodulin, and human neutrophil elastase), the study was terminated earlier than planned. While this study does not specifically address cerebral complications of malaria, the results suggest that POF is not useful as a routine adjunct to the standard therapy of falciparum malaria.

We have tried to correlate abnormalities in electrogastrography (EGG) and gastric emptying (GE) with symptom severity in patients with functional dyspepsia. Seventy-two patients with functional dyspepsia underwent EGG, GE, and symptom severity quantitation. EGGs were assessed for dominant frequency (DF), percentage of time of DF in the 2 to 4 cpm range, and postprandial-fasting DF power ratio. Solid-phase GE scintigraphy was assessed for 2-hour percentage retention. Symptoms of upper abdominal discomfort, early satiety, postprandial abdominal distension, nausea, vomiting, and anorexia were graded as none (0), mild (1), moderate (2), and severe (3); the sum represented a total symptom score. The EGG was abnormal in 11 of 22 (50%) patients with delayed GE compared with 11 of 50 (22%) with normal GE (p < 0.025). The total symptom scores were higher in patients with both delayed GE and abnormal EGG compared with patients with normal GE and EGG, normal GE and abnormal EGG, and delayed GE and normal EGG. We conclude that EGG abnormalities are more common in dyspeptic patients with delayed GE. Patients with both delayed GE and abnormal EGG have more severe symptoms. Our results suggest that EGG and GE complement each other in correlating symptoms to gastric dysmotility.

The purpose of this pilot study was to evaluate the acute gastrointestinal morbidity of adjuvant radiotherapy (RT) for Stage I seminoma of the testis. Ten Stage I patients receiving para-aortic and ipsilateral pelvic nodal (dog-leg) RT provided a toxicity baseline (group A). Twenty Stage I patients, randomized to dog-leg RT or para-aortic RT (10 per group) were further randomized to received prophylactic ondansetron or expectant therapy with metoclopramide (group B). Daily patient-completed questionnaires evaluated acute toxicity. In group A (n = 10), nausea, vomiting, diarrhoea and abdominal discomfort were experienced in 90%, 80%, 70% and 90% respectively. Antiemetic and antidiarrhoeal agents were required in 70% and 10% respectively, with good response. For group B (n = 20), the overall incidences of nausea, vomiting diarrhoea and abdominal discomfort were 80%, 45%, 60% and 80% respectively. The ondansetron group experienced less nausea (P = 0.02) and less vomiting (P = 0.06). Both reduced field size and ondansetron groups appeared to have less diarrhoea (P = 0.06). The use of antiemetics in the expectant therapy groups resulted in at least a two-level reduction of toxicity grade in 86% of patients. A high incidence of lethargy, anorexia and headaches was noted for all groups. The incidence of headaches was not increased with ondansetron. Dog-leg RT for Stage I seminomas is associated with readily demonstrable gastrointestinal tract (GIT) toxicity. The number of patients in this study is too small to produce definitive results, but there appears to be reduced GIT toxicity with prophylactic antiemetics. The effect of reduced RT fields has been assessed further in the MRC randomized trial of field sizes (TE10).

Fourteen patients with unresectable primary or metastatic liver cancer were divided into two groups: group A, continuous hepatic arterial infusion of 5-FU in 10 cases; group V, continuous intravenous infusion of 5-FU in 4 cases. In group A, 5-FU (360 mg/m2/day x 5 days/week x 4 weeks) was continuously infused into the hepatic artery via femoral or gastroduodenal artery through Infuse A Port. In group V, 5-FU (360 mg/m2/day x 2 weeks) was continuously infused into the subclavian vein through IVH route. On day 1, the concentration of 5-FU in peripheral blood in group A (12.1 +/- 12.8 ng/ml) was significantly lower than in group V (43.8 +/- 19.8 ng/ml, p = 0.004). On day 5, it was also decreased in group A (24.6 +/- 24.1 ng/ml) compared with that in group V (61.8 +/- 34.4 ng/ml, p = 0.039). Side effects of 5-FU like nausea, abdominal discomfort and stomatitis were recognized in 4 out of 10 patients in group A (40%) and 3 out of 4 patients in group V (75%). In group A, a complete response was obtained in one patient with synchronous multiple liver metastases of sigmoid colon cancer. These results suggest that systemic toxicity of 5-FU is alleviated by continuous hepatic arterial infusion in the patients with unresectable liver cancer because of its low concentration in peripheral blood.

Cyclospora cayetanensis has been observed in the feces of persons with prolonged diarrhea. A description of the symptoms and histopathologic findings for patients with cyclosporiasis is presented. The intracellular life-cycle stages of these parasites in the enterocytes of patients will also be described. Seventeen Peruvian patients positive for Cyclospora organisms were surveyed and underwent endoscopy, and their symptoms were recorded. Patients presented with gastrointestinal symptoms, including diarrhea, flatulence, weight loss, abdominal discomfort, and nausea. Jejunal biopsies showed an altered mucosal architecture with shortening and widening of the intestinal villi due to diffuse edema and infiltration by a mixed inflammatory cell infiltrate. There was reactive hyperemia with vascular dilatation and congestion of villous capillaries. Parasitophorous vacuoles contained sexual and asexual forms. Type I and II meronts, with 8-12 and 4 fully differentiated merozoites, respectively, were found at the luminal end of epithelial cells. These findings demonstrate the complete developmental cycle associated with host changes due to Cyclospora organisms.

Dyspepsia is a vague term for the nonspecific symptoms of upper abdominal discomfort, prolonged postprandial fullness or early satiety, nausea, vomiting, and upper abdominal bloating. Many common and accepted diseases and disorders such as gastroesophageal reflux and irritable bowel syndrome cause dyspepsia symptoms; these disorders should be identified and treated. However, many patients with dyspepsia symptoms have normal radiographic and endoscopic evaluations; in these patients, neuromuscular of functional disorders of the stomach ranging from gastric dysrhythmias to gastroparesis may be the cause of dyspepsia symptoms. A practical approach to the evaluation and treatment of dyspepsia symptoms attributed to gastric neuromuscular dysfunction of unknown origin is described.
