Aims:To study clinical features of adult patients with idiopathic generalized epilepsy with special attention to suicidal behavior. Methods:We reviewed the medical records of 145 consecutive adult patients with electro-clinically confirmed idiopathic generalized epilepsy and identified those with a history of at least one attempted suicide. Clinical variables in relation to their epilepsy and psychiatric conditions were analyzed.Results: Seven patients (4.8%) had a history of suicide attempts with drug overdose, and one of these patients committed suicide after multiple attempts. All attempts were made interictally without direct relation to their epileptic seizures. All had at least one co-morbid mental disorder (two with dual diagnosis). Although their psychiatric diagnoses varied, they all appeared to have increased emotional instability and poor impulse control. Only one patient's attempt was directly associated with her co-morbid depression.Conclusions: Physicians managing people with epilepsies should be aware of psychiatric disturbances and suicidal behavior in idiopathic generalized epilepsy.

BackgroundDiabetes mellitus (DM) and primary aldosteronism (PA) have been reported to induce drug-resistant hypertension and atherosclerosis. It is likely that blood pressure (BP) control becomes far more difficult in PA patients with DM. However, precise clinical characteristics of PA with type 2 DM especially in the aspect of BP control are not clear.MethodsThe study included 18 patients who were diagnosed as PA with DM and 52 PA patients without DM who matched age and sex and chosen as a control group. We have compared differences in BP control, use of antihypertensive agents and clinical characteristics between PA patients with and without DM.ResultsThere was no difference with regard to the duration of hypertension and BP control between either group. Interestingly, the PA with DM group was found to require more antihypertensive agents than the PA without DM group (number of antihypertensive agents used, 2.0 ± 1.5 vs. 1.3 ± 1.1; P < 0.05, respectively). In the 28 patients who underwent measurement of central BP (CBP) values, plasma aldosterone concentration (PAC) was high in the PA with DM group. Furthermore, a positive correlation was shown between PAC and CBP (r = 0.58; P < 0.01); the higher the PAC, the higher the CBP of patient.ConclusionsThese results might suggest that hypertension becomes more difficult to control in PA patients with DM in the future.

A 26-year-old Japanese man was admitted to our unit with exacerbated paranoid schizophrenia. Prior to his admission, daily administration of olanzapine had been sufficient to maintain a partial remission of his schizophrenia, but due to an exacerbation of his delusions, he had then also been prescribed aripiprazole, which had been followed by no improvement in symptoms and a gradual further exacerbation of auditory delusions. Physical examinations, brain MRI and neurophysiological assessment were unremarkable. Blood analysis, however, revealed extremely low thyroid-stimulating hormone (TSH) and prolactin-releasing hormone (PRL) concentration. Interestingly, after aripiprazole discontinuation, he returned to partial remission with an increase in plasma TSH and PRL concentration.

A morphological study using the Golgi impregnation method was carried out on the anterior horn cells at cervical (C), thoracic (Th), and lumbar (L) levels of the spinal cord in a patient with neuronal type of Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy type II) and an age-matched control. The present study demonstrated an uneven cell body surface, loss of cells (particularly large cells), loss of dendrites, reduced dendritic extent and an irregular surface and shape of dendrites at the C and L levels. In contrast, hematoxylin and eosin and Klüver-Barrera staining showed only simple atrophy or no change. The Th level of the patient showed none of these changes. Our results suggest that the degeneration or loss of dendrites of anterior horn cells by the Golgi staining method, which is most severe at the L level, is closely related to clinical findings such as muscle atrophy and weakness in neuronal type of Charcot-Marie-Tooth disease.
