Electrocardiographic changes during migraine attacks.
OBJECTIVES: To clarify whether electrocardiographic (ECG) changes can be identified during a migraine attack and to determine whether there are ECG differences between periods with and without headache. BACKGROUND: The clinical signs and symptoms of migraine point to involvement of the autonomic nervous system, and especially to disrupted regulation of the circulatory system and autonomic balance. This disruption may be more marked during a migraine attack. During a migraine attack, autonomic imbalance within the heart and its vessels conceivably may result in ECG abnormalities. METHODS: In 30 patients with migraine, the ECG variables of heart rate, abnormalities of rhythm, PR interval, QRS duration, corrected QT interval, T inversion, and ST-segment changes were recorded during migraine attacks and pain-free periods. RESULTS: Of the 30 patients studied during a migraine attack, 9 (30%) had one or more abnormalities of rhythm (including sinus arrhythmia, atrial premature contraction, and ventricular premature contraction), 20% had PR intervals greater than 0.20 seconds, 40% had corrected QT intervals greater than 0.44 seconds, 66% had T inversion, and 40% had ST-segment abnormalities. No patient had arrhythmia, PR intervals greater than 0.20 seconds, or corrected QT intervals greater than 0.44 seconds during a pain-free period. No differences were noted for ST-segment changes, T inversion, and total ECG changes between periods with and without headache, but both PR and corrected QT intervals were significantly longer during migraine attacks than during pain-free periods. CONCLUSIONS: We conclude that ECG abnormalities often are present during a migraine attack, and for most of these, particularly PR and corrected QT interval lengthening, these abnormalities will be absent or less prominent during pain-free intervals.

Basic toxicological approach has been effective in two poisoned patients with amitraz ingestion: case reports.
Amitraz, a formamidine insecticide and acaricide used in veterinary practice, presents side effects in humans related to its pharmacological activity on alpha 2-adrenergic receptors. There is little information available in the literature about the toxicology of the product in man and the treatment of this poisoning. In this report, the clinical and laboratory features of amitraz poisoning in two patients by a veterinary formulation also containing xylene are presented. The major clinical findings were unconsciousness, drowsiness, respiratory failure requiring mechanical ventilation, miosis, hypothermia and bradycardia. The laboratory findings were hyperglycemia, hypertransaminasemia and increased urinary output. Supportive management of this poisoning in humans is suggested in only a few articles and there is no specific antidote for the subsequent possible pharmacological effects of amitraz. In our two cases, we performed supportive treatment such as mechanical ventilation, atropine, gastric lavage, active carbon, oxygen and fluid administration. We concluded that the basic approach to the patient with amitraz poisoning, including initial stabilization to correct immediate life-threatening problems, treatment to reduce absorption and measures to improve elimination of the toxin, is effective.

Protective effects of sucralfate and omeprazole on gastric mucosal damage induced by ethanol in rats.
Studies on the protective effect of omeprazole, a proton-pump inhibitor, against damage to the rat gastric mucosa induced by strong irritants, are few and contradictory. We have investigated the protective effects of omeprazole and sucralfate against gastric mucosal damage induced by ethanol in rats. The study was performed on 4 groups of 10 rats each. Group A received omeprazole 7 mg/kg/day intraperitoneally (i.p.) for 7 days. Group B received an equivalent volume of 0.9% sodium chloride i.p. for 7 days, while no drugs were given to groups C and D. After 1 week, following 24 hours of fasting, group A received omeprazole 7 mg/kg, group B received an equivalent volume of 0.9% sodium chloride group C received omeprazole 7 mg/kg i.p. and group D received sucralfate, 100 mg/kg intragastrically (i.g.). 4 hours after groups A, B and C received the last medication and 30 minutes after group D received sucralfate, ethanol 95% was given i.g. All rats were sacrificed 1 hour after ethanol application and their stomachs were removed for macroscopic and microscopic examination. It was found that sucralfate was effective in preventing gastric lesions induced by ethanol. There was a significant difference between the sucralfate group and the other group (p < 0.001). Omeprazole was ineffective in preventing gastric lesions, either given as a single dose or after administration for 7 days. Our results indicate that sucralfate has a protective effect on gastric lesions induced by ethanol and omeprazole applied i.p. has no protective effect.

Oral high-dose methylprednisolone and intravenous immunoglobulin treatments in adult chronic idiopathic thrombocytopenic purpura.
Ten adult patient of chronic idiopathic thrombocytopenic purpura (CITP) used oral prednisone and were treated with seven doses of oral high-dose methylprednisolone (30 mg/kg). Nine of ten patients responded after HDMP treatment (plt > 150 x 10(9)/L). Two patients having 8 and 10 years of history achieved long-term remission after first HDMP treatment. One unresponsive and one responsive patients did not accept IVIG treatment as second therapy and lost the follow-up. The remaining six patients received IVIG (0.5 mg/kg for 5 days) as second therapy after 3 months. Platelet count increased above 150 x 10(9)/L in 4 patients and between 60-80 x 10(9)/L in 2 patients. The peak platelet counts of both therapy users were higher under HDMP than IVIG therapy (252 +/- 110.4 vs 174.2 +/- 83.7 x 10(9)/L), but the difference was not significant. Responses were transient and returned to pretreatment values at 14-30 days, excluding long-term remission of 2 (2/10) patients after HDMP treatment. No side effect was observed. Thus, oral HDMP appears a good initial therapy for continuous remission in a small ratio of patients and a good security for emergency situations and prior to surgery in adult CITP patients.

Weil's disease: report of 12 cases.
The epidemiological distribution and clinical features of 12 cases of Weil's disease from Turkey, are reviewed. The disease is most common in male farmers from rural areas. Myalgia and jaundice were recorded in all patients. Signs included vomiting in 9 patients, haemorrhages in 6, and renal function was impaired in 6. Creatine phosphokinase levels were found above normal limits in 75% of the cases. Leptospires were demonstrated with dark-field microscopy in the blood of 9 and in the urine of 5 of these patients. The diagnosis was confirmed with microscopic agglutination test (MAT) as well as with ELISA. Ig M antibodies were detected in 11 (92%) of the patients and is an accurate marker for acute leptospirosis. Penicillin was used for therapy and the outcome was favorable in 10 patients. Two patients died. It should be kept in mind that leptospirosis is an extremely severe disease which requires appropriate examinations at the right moment.
