Lipid profile and thyroid hormone concentrations in children with epilepsy treated with oxcarbazepine monotherapy: a prospective long-term study.

BACKGROUND AND PURPOSE: To evaluate prospectively the changes and possible associations in lipid and thyroid profiles in children treated with oxcarbazepine (OXC) monotherapy. METHODS: Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), lipoprotein (a) [Lp(a)], free thyroxine (FT4), free triiodothyronine (FT3), thyrotropin (TSH) and gamma-glutamyltransferase (GGT) concentrations were measured in 23 children with epilepsy, before and at 8 and 18 months of OXC monotherapy. RESULTS: Total cholesterol was significantly increased at 8 months (P = 0.033), whereas LDL-C was significantly increased at 8 and 18 months (P < 0.001 and P = 0.004, respectively) of treatment. Lp(a) was significantly increased at 8 months (P = 0.042) and borderline significantly increased at 18 months (P = 0.050) of treatment. FT4 was significantly decreased at 8 and 18 months (P < 0.001 and P = 0.002, respectively), and TSH levels were significantly increased at 8 and 18 months (P = 0.002 and P = 0.001, respectively) of OXC monotherapy. GGT levels were significantly increased at 8 and 18 months (P < 0.001) of treatment. There were no significant alterations in HDL-C, TGs and FT3 levels during the study. Significant positive correlations were found between GGT and LDL-C levels at 8 (r = 0.468, P = 0.024) and 18 months (r = 0.498, P = 0.016), and between TSH and TC at 18 months (r = 0.508, P = 0.013) of treatment. CONCLUSIONS: OXC monotherapy may cause significant and persistent alterations in lipid and thyroid profiles in children with epilepsy. The increase in LDL-C and TC levels may be associated with liver enzymes induction and thyroid dysfunction. Further long-term prospective studies are required to confirm these findings and to determine their clinical significance.

Cohen syndrome: two new cases in siblings.

UNLABELLED: Cohen syndrome is a rare genetic disorder consisting of truncal obesity, hypotonia, mental retardation, characteristic facial appearance and ocular anomalies. Other diagnostic clinical features include narrow hands and feet, low growth parameters, neutropenia and chorioretinal dystrophy. We describe the similarities in the clinical and developmental profile of two siblings with Cohen syndrome, providing evidence for autosomal recessive inheritance in this condition. CONCLUSION: The diagnosis of Cohen syndrome should be suspected in mentally retarded children with the above characteristics. Neutropenia and ocular anomalies with high-grade myopia and chorioretinal dystrophy are also considered important findings and can aid in the clinical diagnosis especially at an early age.

Ternary Complexes of cis-(NH(3))(2)PtCl(2) (cis-DDP) With Guanosine (guo), Cytidine (cyd) and the Aminoacids Glycine (gly), L-Alanine (ala), L-2-Aminobutyric Acid (2-aba), L-Norvaline (nval) and L-Norleucine (nleu).

The ternary complexes of formulae cis-[(NH(3))(2)Pt(nucl)(amac)]NO(3), where nucl = guo and cyd (guanosine and cytidine) and amac = the deprotonated aminoacids glycine (gly), L-alanine (ala), L-2-aminobutyric acid (2-aba), L-norvaline (nval) and L-norleucine (nleu), were prepared from the reactions of the binary chelated ones cis-[(NH(3))(2)Pt(nucl)(amac)]NO(3) with the nucleosides.They were characterized by (1)H, (13)C and (195)Pt NMR and IR spectra, together with elemental analysis and conductivity measurements. The aminoacids coordinate with Pt(II) in the ternary complexes with their terminal -NH(2) groups, guo through N(7) and cyd through N(3). Ligand-ligand hydrophobic interactions were also observed in the ternary complexes and were stronger with longer aliphatic chains of the aminoacids. The (3)E sugar conformation increased by 5-7% in the ternary systems, as compared to the free nucleosides, while the percentage of the gg conformation remained almost constant and the one of the anti conformation of the sugar increased also slightly. Finally, the h conformer around the C(alpha)-C(beta) bonds of the aminoacids reached a maximum in the binary systems and decreased again considerably in the ternary ones.

Risk factors for cerebral palsy: a case-control study in Greece.

The purpose of this study was to investigate the relation between a series of maternal, antenatal, perinatal, socioeconomic and environmental variables and the occurrence of cerebral palsy (CP) in a setting different from those in which previous analytic epidemiologic studies had been undertaken. The study was of case-control design and included 103 children with cerebral palsy born between 1984 and 1988 and residents of the Greater Athens area at any time during 1991 and 1992. Controls were chosen among the neighbors of the index case or were healthy siblings of children with neurological diseases other than CP seen by the same neurologists as the children with CP; a total of 254 control children were eventually included. Statistical analysis was done by modeling the data through unconditional logistic regression. Statistically significant (p < 0.05) risk factors of potential causal importance were: twin membership (OR = 10.2), gestational age (OR = 0.5 per 4 weeks), birth weight conditional on gestational age (OR = 0.9 per 100 g), congenital malformations (OR = 7.5), unhealthy placenta (OR = 6.6), placenta previa (6 cases, no controls), abnormal amniotic fluid (OR = 3.6), head circumference more than 36 cm (OR = 9.0), general anesthesia during labor (OR = 4.3), forceps delivery (OR = 6.8), and birth trauma (OR = 11.5). Among children with no identifiable prenatal risk factors there was no excess prevalence of one or more perinatal risk factors in CP cases compared to controls, which implies that the latter factors impart their effect through interactions with co-existing prenatal or other risk factors.

Age of pubertal stages including menarche in Greek girls.

The age at the different stages of pubertal development, including menarche, was assessed by the status quo method in 1366 middle-class girls living in Athens. The initial pubertal event in the average Athenian girl was the appearance of pubic hair along the labiae (P10:8.85, P50:10.47), followed shortly by breast budding (P10:9.39, P50:10.62), and later on by axillary hair growth (P10:10.55, P50:11.63). The age at menarche was 12.58 +/- 0.07 years. It seems tht Athenian girls of 1979 have one of the earliest ages of menarche reported. Recollected age data on menarche when compared to previous data from the Greek population show a decrease of 0.46 years/decade from 1935 to 1964 and no appreciable change from 1964 to 1979. Although these data are not absolutely comparable from the methodological point of view, they may indicate that the trend in menarcheal age in Athens is levelling off.
