During Ramadan, Moslems are required strictly to avoid fluids and nourishment from dawn to sunset. Heat stress during such abstinence represents a substantial health hazard. In the Federal Republic of Germany (FRG) where numerous Moslems, particularly of Turkish origin, perform heat work and other heavy labour, we observed moderate to severe health disturbances in such labourers during Ramadan, e.g.: tachycardia, severe headaches, dizziness, nausea, vomiting and circulatory collapse. The severe dehydration of these workers was demonstrated by substantial increases in their hematocrit, serum protein, urea, creatinine, uric acid and electrolyte imbalance. Because of the evidence of the substantial health hazard to Islamic workers in such situations, we have strongly urged employers to refrain from assigning Islamic workers to heat work or heavy daytime work during Ramadan; we have therefore limited systematic studies of health problems during Ramadan to persons performing only moderate work. Even under these conditions signs of dehydration were found in the 32 labourers monitored. Some of these labourers also had to interrupt their observance of Ramadan due to health problems, e.g.: acute gout due to serum uric acid increase, or circulatory insufficiency. In light of the observed potentially harmful pathophysiological effects, the danger of dehydration of Islamic workers due to heat work during Ramadan should be taken very seriously.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirteen normal subjects were given 2, 3, or 4 g of ceftizoxime intravenously in a prospective single-blinded study. Serum and urine concentrations were measured for 48 h. The beta-phase serum half-life ranged from 1.4 to 1.7 h. Approximately 100% of the agent was recovered unchanged in the urine over 48 h. Six of 13 subjects reported subjective complaints consisting of mild dizziness and moderate headache, all of which were transient. One subject also had a minimally elevated serum glutamic oxalacetic transaminase level 1 day after drug administration. Based on serum pharmacokinetics and serum protein binding determined in this investigation, unbound ceftizoxime appeared to distribute with the total body water.

Cinoxacin, a chemotherapeutic agent that inhibits bacterial DNA synthesis, has recently been approved for the treatment of initial and recurrent bacterial urinary tract infections. Although closely related to nalidixic acid, cinoxacin possesses some distinct characteristics: rapid attainment of therapeutic urinary concentrations and greater activity against strains of Enterobacteriaceae that cause urinary tract infections. Biopharmaceutical properties include serum protein binding of approximately 70%, 50-60% excretion of intact drug in the urine of patients with normal renal function, and an elimination half-life of approximately one hour. The elimination half-life is increased in patients with decreased renal function and when probenecid is coadministered. Adverse events occur infrequently and consist of nausea, vomiting, headache, dizziness, and hypersensitivity reactions. The drug compares favorably with standard therapies for the treatment of bacterial cystitis and recurrent urinary tract infections. Initial studies demonstrate that cinoxacin has substantial efficacy as a prophylactic agent for those women who experience recurrent, symptomatic urinary tract infections.

The safety and efficacy of Trigonella foenum-graecum extract was investigated using 20 male volunteers aged 20-30 years. They were randomly treated with either 40 mg/kg aqueous extract powder in 10 mL distilled water or 10 mL distilled water in which coffee simulated the extract. The extract significantly lowered blood glucose level by 13.4% 4 hours after ingestion. A significant change of 14.1% was observed in potassium levels. No significant alteration in serum cholesterol, total serum protein and blood urea occurred. Approximately one-third experienced feelings of hunger, frequency of micturition or dizziness during the 24 hours after ingestion. The aqueous extract effectively reduced blood glucose in normal subjects safely. Its hypokalaemic effect merits further investigation.

Reactions to oral contraceptive therapy tend to be maximal during the first few months of use. They include nausea or epigastric discomfort, malaise, dizziness, nervousness, fatigue, weakness, leg cramps, headache, and depression. The estrogenic component is thought to be the cause. There may also be a psychogenic basis reflecting apprehension. Breast tenderness is an occasional complaint and intermenstrual spotting or breakthrough bleeding is often reported. Increasing dosage has reduced this symptom. Dysmenorrhea prior to treatment may be improved but occasionally it is aggravated. Drug-induced amenorrhea presents a double problem in that failure to resume medication 7 days after completion of a cycle results in a risk of conception. Episodes of severe uterine bleeding in patients discontinuing use after several months or years have been reported. Other side effects include a skin reaction resembling acne, pruritus, hirsutism, thinning of scalp hair, increased skin pigmentation, and weight gain or loss. Serious vascular complications and hepatic dysfunction have been shown and deviation of thyroid function may be shown by increase of serum protein-bound iodine (PBI). Clinical signs of hyperthyroidism have not been described. Oral contraception is associated with elevated plasma cortisol (hydrocortisone) levels and decreased urinary levels of 17-hydroxycorticosteroids (17-OCHS). Suppression of ovarian activity by oral contraceptives is rapidly reversible. Fear of carcinogenesis has caused much alarm but no proof as of the present time. Safety of long term use will require additional years of experience.

A small proportion of patients with mild head injury (MHI) develop post-concussion symptoms (PCSs). We searched simple measures for the early detection of patients who are probable to develop PCSs. We recorded signs and symptoms, history of previous diseases, medications, and lifestyle factors and measured serum protein S-100B on admission in a series of 172 consecutive MHI patients admitted into the emergency room of a general hospital. A modified Rivermead Post-Concussion Symptoms Questionnaire was used to identify the patients with and without PCSs 1 month after the injury. We identified 37 patients with MHI who developed PCSs (22%). Odds ratios (OR) and 95% confidence intervals (CI) after adjustment for possible confounding variables were calculated by logistic regression. Independent early risk factors for PCSs in the MHI patients were skull fracture (OR 8.0, 95% CI 2.6-24.6), serum protein S-100B >/= 0.50 microg/l (OR 5.5, 95% CI 1.6-18.6), dizziness (OR 3.1, 95% CI 1.2-8.0), and headache (OR 2.6, 95% CI 1.0-6.5). Serum protein S-100B proved to be a specific, but not sensitive predictor of PCSs. The presence of skull fracture, elevated serum protein S-100B, dizziness, and headache may help the emergency room physician to identify patients at risk of PCSs and to refer them for further examination and follow-up.

A 44-year-old male presented with dizziness, blurring of vision, unproductive cough, dyspnoea, heaviness of head, fever and hepatosplenomegaly along with reticulonodular infiltration in chest x-ray. His serum showed monoclonal IgM gammopathy. Peripheral blood smear, bone marrow examination and serum protein electrophoresis suggested it was a case of Waldenstrom's macroglobulinaemia. Chest x-ray and CT scan of thorax were suggestive of pulmonary involvement in the form of interstitial lung disease.
