Five children with adrenocorticotropic hormone (ACTH) insensitivity associated with autonomic nervous system disorders are described. At the time of diagnosis, four of them had osteoporosis. The fifth patient died and skeletal roentgenograms were not done. Osteoporosis was subsequently discovered in one of our previously reported patients with ACTH insensitivity. We assume that osteoporosis is, at least partly, the result of decreased adrenal androgen production. Human leucocyte antigen typing failed to establish any linkage.
AimTo determine the prevalence, number, and location of multiple (≥2) T2-hyperintensities on brain magnetic resonance imaging (MRI) in children with neurofibromatosis type 1 (NF1) and their correlation with age, and to establish their sensitivity, specificity, and accuracy for the diagnosis of NF1 in children, especially in the early age (2-7 years).MethodsWe performed a cross-sectional study of 162 patients with NF1 from Croatian Neurofibromatosis Association Database and 163 control children between the ages of 2 and 18 years who underwent brain MRI between 1989 and 2009.ResultsMultiple T2-hyperintensities were present in 74% of NF1 patients and 1.8% of controls. They were mainly located in the basal ganglia, brainstem, and cerebellum and were significantly decreased in prevalence and number in the older age. T2-hyperintensities had excellent diagnostic accuracy with the area under the receiver operating characteristic (ROC) curve of 0.849 and 95% confidence interval (CI) of 0.805-0.886. The diagnostic sensitivity, specificity, and accuracy rate of T2-hyperintensities for NF1 were highest in the youngest age (2-7 years): 81% (95% CI 71%-89.1%), 99% (95% CI 92.3%-100%), and 85.8 (95% CI 83.3-93.8), respectively.ConclusionThis study strongly suggests the inclusion of T2-hyperintensities on brain MRI on the list of diagnostic criteria for NF1, especially in children of early age, when the clinical penetration of the NF1 gene has not yet been completely finished.
SUMMARY -Epilepsy is the most common neurological complication in pregnancy. Women with epilepsy have a higher risk of complications in pregnancy. In Croatia, women with epilepsy are treated by neurologists at tertiary centers according to the place of residence. We prospectively followed-up pregnancies in women with epilepsy and healthy controls, and analyzed the factors responsible for their delivery outcomes and development of their babies. Healthy pregnant women had a higher level of education and economic status, but pregnant women with epilepsy took folic acid in a higher proportion than controls, possibly due to timely preconception counseling. Complications during pregnancy depended on the number of antiepileptic drugs and epilepsy control. We noticed some behavioral and cognitive aspects in children exposed in utero to valproic acid, which required follow up. Th e rate of congenital malformations was not increased. In conclusion, women with epilepsy should receive preconception counseling about the risk for pregnancy, but also about the possibilities to minimize that risk. We have introduced a model of integrative management of pregnancy and epilepsy based on close collaboration among diff erent clinical experts in Croatia, in order to provide prompt counseling and timely intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
