Association of interleukin 4 and MTHFR gene polymorphisms with distal symmetrical polyneuropathy in young diabetics.

Background:  It is believed that genetic factors play a role in the development and severity of neural injury among people with distal symmetrical polyneuropathy (DSP), because some genes are involved in specific biological pathways, acting in different ways in the pathogenic process.

Objective:  To identify potential associations involving the ( C677T) and ( intron 3 variable number of tandem repeats [I3VNTR]) gene polymorphisms and DSP in the studied sample.

Methods:  In total, 70 children and adolescents with type-1 diabetes underwent a nerve conduction studie (NCS) of the sural nerve.

Auditory brainstem function in microcephaly related to Zika virus infection.

Objective: To study the effect of prenatal Zika virus (ZV) infection on brainstem function reflected in brainstem auditory evoked potentials (BAEPs).

Methods: In a cross-sectional study in 19 children (12 girls) with microcephaly related to ZV infection, aged between 12 and 62 weeks, the brainstem function was examined through BAEPs. The latencies of wave peaks I, III, and V of the left and right ears (n = 37) were standardized according to normative data, and compared between them by 2-tailed test.
