[Epilepsy and pregnancy: antiepileptic drugs effects on pregnancy]. / Epilepsija i trudnoca--primjena antiepileptika u trudnoci.

PURPOSE: The aim of our study was to analyse the antiepileptic drugs (AEDs) usage in pregnant women with epilepsy, and to evaluate possible complications of this therapy during pregnancy and delivery as well as fetal effects of there drugs. METHODS: This retrospective study was conducted in the University Hospital Center Rijeka, Croatia, during the ten-year period (Jan 1, 1993-Dec 31, 2002). The study included 151 pregnant women with epilepsy. Data were entered in a structured form for evaluation of patient general data and data on antiepileptic therapy and neonatal outcome according to the use of AEDs. RESULTS: During the study period, 185 children (male 95) were born. Twenty-four miscarriages were recorded in women with the diagnosis of epilepsy in their medical history. In 117 of women, the onset of epilepsy occurred before the age of 20 years. AEDs were used in 111 of patients, in 77% of them as monotherapy. The most frequently used AEDs were carbamazepine (36.2%), valproate (29.3%), phenobarbitone (24.1%). Folic acid was used in 25 pregnancies only, however, during 2002 folic acid was used in 15 pregnancies (yielding 22 in total). Apgar score was equal or higher than 8/8 in 96% of children. No specific teratogenic effects were observed. CONCLUSION: Study results showed standard AEDs to be most commonly used in the study population, entailing no major birth defects, thus the potential risk probably being rather low. In the study population of pregnant women with epilepsy, the use of folic acid improved in 2002 in comparison to the previous period.

Make love to forget: two cases of transient global amnesia triggered by sexual intercourse.

Transient global amnesia (TGA) is characterized by a sudden onset and by a typical resolution within several hours. Several precipitating events have been proposed: physical exertion, emotional experiences, etc. The aim of this paper was to present two cases of TGA triggered by sexual intercourse and to suggest a possible mechanism for the development of TGA. In both patients, clinical examination revealed elevated blood pressure. Laboratory examinations and brain CTs were normal. EEG demonstrated diffuse dysrhythmia and slow spike-waves, respectively. SPECT revealed hypoperfusion in the left frontal and right medial temporal regions. Various explanations of the mechanism of TGA are discussed. Based on the observed hypoperfusion in the medial temporal regions, a new hypothesis is advanced, suggesting the possibility that TGA occurs due to a pathologically changed or less adaptable anterior chorioid artery, initially constricted by hypotension following a blood shift from the center towards periphery.

Epidemiology of primary central nervous system tumors in the Coast and Gorski Kotar County, Croatia, 1977-2000.

AIM AND BACKGROUND: To establish the incidence of primary tumors of the central nervous system (CNS) in the resident population of the Coast and Gorski Kotar County, Croatia, in the period 1977-2000. METHODS: A retrospective descriptive epidemiological study. Tumors were classified according to the World Health Organization's scheme. A total of 911 cases was identified. Information about patient gender and age at diagnosis, tumor location and histologic type was obtained from case histories, autopsy protocols and pathology reports. Age- and sex-adjusted incidence were determined by a direct standardization method. RESULTS: Histologic confirmation was obtained in 84.5% of cases. The most frequent tumors were glioblastoma in men (30.2%) and meningioma in women (29.5%). The average annual crude and world-standardized incidence was 11.2 (95% CI, 10.1-12.3) and 8.2/100,000/year (95% CI, 7.4-9.0), respectively. The highest specific age incidence was detected in the seventh decade of life, 24.7/100,000/year (95% CI, 21.4-28.8). The tumors occurred equally in each sex. The lowest incidence was detected on the islands, 7.4/100,000/year (95% CI, 5.9-9.2) and the highest along the coast, 12.7/100,000/year (95% CI, 11.4-14.0). The survey showed the highest incidence of these neoplasms in the coastal municipality of Senj, 14.7/100,000/year (95% CI, 10.3-20.5). CONCLUSION: The descriptive epidemiological incidence of primary CNS tumors in the Coast and Gorski Kotar County, Croatia, especially those of neuroepithelial and meningeal origin, correspond to the data reported in similar studies elsewhere in the world. The incidence of these neoplasms in the area investigated is uneven. Limitations in study design preclude definitive conclusions about the causes of these differences.
