Eight-five of 816 (10.7%) students attending a primary school in Central Thailand were examined and found infected with Fasciolopsis buski. All of students ate fresh water lily stems and most ate other fresh water plants including caltrop, water cress and morning glory. The 85 students were given praziquantel in randomized single doses of 15, 25 or 40 mg/kg body weight. Side effects were mild and transient and consisted of headache, dizziness, nausea, sleepiness, abdominal discomfort, anorexia, diarrhea, epigastric pain, vomiting and lassitude. Those receiving the highest dosages had more side effects than students in the other 2 groups. Large blisters were observed on the tegument of F. buski passed in feces and this was believed to be caused by the drug. The authors recommend a single dose of praziquantel in a dosage of 15 mg/kg of body weight for the treatment of parasitosis.

45 patients wih degenerative joint diseases (osteoarthrosis of the hip or knee, Heberden's nodes) were treated for 5 weeks in an open controlled trial with Sulindac, a new nonsteroidal antirheumatic drug (300-400 mg daily). The effectiveness of the drug was evaluated by the following criteria: changes of pain intensity with active movements, pain at rest, night pain, duration of morning stiffness and limitation of movement. Analysis of the global data showed in 64,4% excellent results. In 9.9% the results were good, in 17,8% moderate and there was no response in 6.6%. Other side effects (epigastric pain 8,9%, dizziness 2,2%) were not serious and reversible during the treatment with Sulindac.

Neuroendocrine pancreatic tumors are neoplasms derived from APUD cells, characterized by hyperincretion of several peptides of hormonal activity. The incidence of these tumor is low. They are usually classified according to the predominant secreted peptide: gastrinoma, insulinoma, VIPoma, glucagonoma. Insulinoma is the most frequent endocrine pancreatic tumor, characterized by a peculiar clinical picture due to insulin action. This neoplasm is prevalently benign (90%), and may cause symptoms due to hypo-glycemia such as epilepsy, asthenia, deep coma, dizziness, hunger and epigastric pain. Surgery still constitutes the principal therapy for insulinoma treatment, but an accurate tumor identification is necessary. Selective arteriography of the pancreas and new diagnostic investigations as intraoperative US, selective sampling of pancreatic veins with insulin Quick-RIA, aid the diagnosis and more precise localization of the tumor. When surgical therapy is not practicable, for diffuse metastases, octreotide has an inhibitory effect upon hormone release, and may be combined with chemotherapy for controlling clinical symptoms. We review the clinical records of 2 patients from our Institute, who had hyper-insulinism due to benign insulinomas of the tail of the pancreas. Surgical treatment was performed with enucleation of the neoplasms.

This paper investigates the acute effects of carbofuran in workers of two pesticide-formulating plants. Mean airborne carbofuran concentrations ranged from 0.025 to 1.115 mg/m3 in plant A and from 0.018 to 0.067 mg/m3 in plant B, respectively. In workers of plant A the post-shift blood cholinesterase activity was significantly reduced, compared to pre-shift values. No difference in blood cholinesterase activity was found between pre- and post-shift values in workers of plant B. During the investigation, 25 cases of acute carbofuran poisoning were diagnosed by their clinical picture and depressed cholinesterase activity in blood. Usual symptoms included dizziness, weakness, blurred vision, nausea and sweating. Pallor, epigastric pain, vomiting and chest tightness occurred only in a few cases. Myosis was recorded in 24 cases. Fasciculation of muscle gastrocnemius induced by percussion was found in 6 cases, and four of them had also fasciculation of muscle orbicularis oculi. Inhibition of cholinesterase activity in the blood was related with the clinical features; however, the inhibition was rapidly reversible. In most cases, recovery was complete within 2-3 hours, with or without atropine treatment, after the subjects were removed from exposure. Rapid onset, mild illness and quick recovery are typical characteristics of occupational acute carbofuran poisoning.

Chronic bronchitis is a debilitating disease affecting many millions of patients globally. They suffer multiple acute exacerbations each year, often requiring many courses of antimicrobials to enable them to return to normal. The impact of the condition on both the individual patient and society as a whole is considerable and growing; thus antimicrobial therapy should induce rapid and effective outcomes as soon as possible. This open, community-based study of 5737 patients enrolled by over 2000 primary care physicians from across Spain examined the clinical effect of oral moxifloxacin on patients' signs and symptoms of acute exacerbations of chronic bronchitis (AECB) over a 45-day period. The symptoms were assessed using daily diary cards in addition to physician evaluations. Clinical assessment at day 7 showed 93.0% of patients were cured. The patient diary card showed that two-thirds of patients felt better by day 3 or 4. Adverse events were reported in 3.5% of patients in this study, the most common being diarrhoea, nausea and dizziness, and epigastric pain. These reactions were mild to moderate in intensity. There were no patient deaths due to infection during the study. Physicians and patients reported that once-daily moxifloxacin gave fast relief of symptoms of acute exacerbations of chronic bronchitis.

Primary choriocarcinoma of the stomach is an extremely rare and highly malignant tumor. A 68-year-old Japanese man was admitted to our department with symptoms of epigastric pain, abdominal fullness, and dizziness. Primary gastric choriocarcinoma with regional lymph node metastases was diagnosed preoperatively by the detection of elevated serum levels of a tumor marker, radiography, and immunohistochemical staining of biopsy specimens. The patient underwent total gastrectomy and jejunal reconstruction (Roux-en-Y method), followed by chemotherapy. Histological examination of the resected stomach revealed typical choriocarcinoma accompanied by common adenocarcinomatous elements. After postoperative chemotherapy the patient survived for 4 years and 6 months, and died with no evidence of recurrence of carcinoma. This is the first known patient with primary gastric choriocarcinoma to have survived for such a long period without recurrent elevation of the serum level of human chorionic gonadotropin (HCG), which was a useful marker when reevaluating the patient.

In Maputo 133 consecutive eclamptic patients were compared with 393 non-eclamptic referent women. Significant risk factors for eclampsia were age < or = 18 years, household size < or = 3 individuals, unwanted pregnancy, walking to antenatal clinics and, in the thrid trimester, headache, foot oedema, hand or face oedema, epigastric pain, visual disturbance, ear buzzing and dizziness. Significantly more cases than referents reported no blood pressure measurements in antenatal clinics. It is concluded that the quality of antenatal clinics can be improved by enhanced community awareness of danger signs, by early recognition of risk factors and by better management of prodromal symptoms of eclampsia.

A 57-year-old man consulted an herbalist for epigastric discomfort. Four hours after he drank a decoction made from 14 herbs, he developed nausea, epigastric pain, and dizziness. He also had two loose bowel movements. On arrival at the hospital 4 hours later, his blood pressure was 77/46 mm Hg, and his pulse was 60 beats/min. He was given intravenous fluids. In the next 3 hours, his blood pressure gradually returned to his usual level of 100/65 mm Hg. His other gastrointestinal symptoms gradually subsided during the next 24 hours. His white cell count was 17.8 x 109/L but was normal on recheck. Complete cell counts, renal function and liver function tests, and electrocardiogram were otherwise normal. He was discharged home on day 2. Seven of the 14 herbs taken by this patient are known to have vasodilatory or blood pressure-lowering effects, and 3 of these herbs are used to manage hypertension. In traditional Chinese medicine, practitioners often use a combination of herbs in an attempt to improve the efficacy but reduce the adverse effects of treatment. The risk of adverse herbal interactions will also be higher.

Treatment of strongyloidiasis has been traditionally based on thiabendazole, despite its frequent gastrointestinal side effects and failure to achieve eradication of the parasite from faeces in approximately 30% of cases. Ivermectin has been shown to be more effective for treating chronic uncomplicated strongyloidiasis. The efficacy and tolerability of these drugs in a series of patients treated from 1999 to 2002 at the Oliva Health Centre, Valencia, Spain, are reported. A total of 88 patients diagnosed of strongyloidiasis were treated using the following regimens: thiabendazole 25 mg/kg/12 h for 3 consecutive days in 31 patients; ivermectin 200 mug/kg as a single dose in 22 patients; and ivermectin 200 mug/kg for 2 consecutive days in 35 patients. The efficacy and side effects were recorded. A total of 65 patients were male, and 23 female. The mean age was 64 +/- 12 years. Of the patients, 44 had worked barefoot in rice fields. Among the 31 patients treated with thiabendazole, 25 (78%) met the criteria for cure (the absence of parasite in faeces after examination of three samples collected on alternate days), and 5 (16%) experienced side effects (asthenia, epigastralgia and disorientation). Of the 22 patients treated with ivermectin on a single day, 17 (77%) met the criteria for cure, and 2 (9%) reported side effects (dizziness, dyspepsia). Among the 35 patients treated with ivermectin on 2 consecutive days, 100% met the criteria for cure, and 0% experienced side effects. In chronic uncomplicated strongyloidiasis, a treatment regimen consisting of ivermectin 200 mug/kg for 2 consecutive days provided the best results with regard to efficacy and tolerability. When the eosinophilia continued after treatment, we observed a high percentage of not-cure rate (7 of 9 patients, 77%).

Strongyloides stercoralis infection is a disease caused by an intestinal parasite. This helminth is highly prevalent in tropical and subtropical areas. The preferred treatment is ivermectin, and thiabendazole as a second option available in certain Peruvian institutions. The purpose of the study was to assess the efficacy and tolerability of thiabendazole (25 mg/kg/day) administered twice a day (after meals) for three days in individuals with S. stercoralis chronic infection. The study was conducted at Hospital de La Merced, Province of Chanchamayo, Peru (endemic area), during a 90 day period. The study included 32 individuals (22 female and 10 male, average age +/- SD = 9.31 +/- 8.11 years) with a diagnosed S. stercoralis infection. Follow up tests were eosinophil count, hematocrit, agar plate feces culture, and Baermann technique modified by Lumbreras. Healing rate was 90.6%. The average eosinophil count in healed patients significantly decreased (1168 to 665 eosinophils/cc, p=0.006) as compared to the treatment failure group, which showed a slight increase (618 to 897 eosinophils/cc, p=0.125). Hematocrit increased in both groups (2% and 3%, respectively). Adverse effects were headache, dizziness, and epigastralgia in 6.2% of individuals. It was concluded that the studied scheme showed a high effectiveness rate and was well tolerated. Therefore this scheme may be taken into account for control programs of this parasite in hyperendemic areas.
