Histological methods (Golgi-Cox and Nissl) were used to study the maturation of the large pyramidal cells of layer V of the occipital cortex in malnourished rats (according to the method of Araya et al.). The main alterations were observed in pyramidal cells of cortical alyer V; These showed a decrease of the number and span of dendritic basilar processes. An increase in cell density was also observed in this layer. We assume that malnutrition during this period of development provokes a derangement which disturbs the process of neuron differentiation, with effects that probably are permanent.
IntroductionNeuroleptic malignant syndrome (NMS) is a serious side effect of the antipsychotic, potentially life-threatening. The NMS is characterized by a distinctive clinical syndrome of mental status change, rigidity, fever, and dysautonomia. Even the newer atypical antipsychotics (AA), which are not classified accurately as neuroleptics, can cause NMS.ObjectivesWe report the clinical course of a NMS in a 37-year-old male with bipolar disorder. The clinical onset and the evolution are described.AimsThe patient was treated with different AA drugs (risperidone and olanzapine), and after a dosage increase of olanzapine extrapyramidal symptoms appeared (muscular rigidity, hyperthermia, dystonia, tachycardia and profuse diaphoresis) and laboratory abnormalities (CK-NAC 21000U/L).The patient is examined and evaluated by a internal medicine physician and moved to the Intensive Care Unit (ICU) where he started hydration using intravenous fluids, antibiotics (meropenem), benzodiazepines (diazepan) and dopamine agonist (bromocriptine). His admission in ICU was 13 days.ResultsThe pathogenesis of NMD in BD is poorly understood. Current theories are limited in their ability to explain all clinical manifestations. Although there is no diagnostic test for NMS, testing has a crucial role in the evaluation of patients with potential NMS. Typical laboratory abnormalities help to confirm the clinical diagnosis.ConclusionsAccording to the literature reviewed, all classes of antipsychotics have been associated with neuroleptic malignant syndrome, including lowpotency neuroleptics, high potency neuroleptics and the newer atypical antipsychotics, so we must monitor patients who start or increase dose of atypical or typical antipsychotics.
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.
