Background: Ventricular hypertrophy is a well-known side effect of adrenocorticotropic hormone (ACTH) therapy in patients with West syndrome (WS), but there are only a few reports of echocardiographic evaluation of these patients' diastolic function.

Methods: The present, retrospective study analyzed echocardiographic findings in 24 patients with WS treated with ACTH therapy between April 2010 and December 2014. The therapy protocol involved administering tetracosactide acetate 0.

Background: Neurogenic pulmonary edema is a rare but serious complication of febrile status epilepticus in children. Comprehensive screening for viral pathogens is seldomly performed in the work-up of febrile children.

Case Presentation: A 22-month-old girl presented with her first episode of febrile status epilepticus, after which she developed acute pulmonary edema and respiratory failure.

Background: Torque teno virus-induced aseptic meningitis has not been documented, although torque teno virus infections still remain under consideration for etiological agents. This study identified a torque teno virus sequence using next generation sequencing and immunoglobulin M response to the torque teno virus antigen, therefore, that would be a comprehensive diagnosis for torque teno virus infection.

Case Presentation: A 2-month-old Japanese boy was brought to our hospital because he was irritable, drowsy, and lethargic.

This case report describes a male neonate with Graves' disease. The mother's pregnancy was complicated by poorly controlled Graves' disease. The neonate was diagnosed with thyroxine (T3)-predominant Graves' disease with low free triiodothyronine (T4) and high free T3 during antithyroid drug therapy.

Background: Streptococcus pyogenes (group A Streptococcus [GAS]) is a major human pathogen that causes a wide spectrum of clinical manifestations. Although invasive GAS (iGAS) infections are relatively uncommon, emm3/ST15 GAS is a highly virulent, invasive, and pathogenic strain. Global molecular epidemiology analysis has suggested that the frequency of emm3 GAS has been recently increasing.

Objective: We performed whole-exome sequencing analysis of patients with genetically unsolved hypomyelinating leukoencephalopathies, identifying 8 patients with TUBB4A mutations and allowing the phenotypic spectrum of TUBB4A mutations to be investigated.

Methods: Fourteen patients with hypomyelinating leukoencephalopathies, 7 clinically diagnosed with hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC), and 7 with unclassified hypomyelinating leukoencephalopathy, were analyzed by whole-exome sequencing. The effect of the mutations on microtubule assembly was examined by mapping altered amino acids onto 3-dimensional models of the αβ-tubulin heterodimer.
