Background: Acute hearing loss is a distressing albeit rare occurrence in pregnancy. Due to its infrequent presentation, little is known of its cause, and the best management is unclear.
Objective: To present a summary of current knowledge regarding sudden hearing loss in pregnancy and its management, by reviewing the published literature.
Data Sources: The following electronic databases: PubMed (MEDLINE), Ovid (MEDLINE), all EBM Reviews (Cochrane DSR, ACP Journal Club, DARE and CCTR) and Embase; plus a hand search of reference lists of retrieved papers.
Study Selection And Data Extraction: All papers retrieved using key word searches for 'sudden hearing loss and pregnancy' and 'sudden deafness and pregnancy' were reviewed. Due to the scarcity of literature, all studies identified were included in this review.
Data Synthesis And Conclusions: All retrieved papers were reviewed. Sudden hearing loss is a rare occurrence during pregnancy, leading to a dearth of literature due to limited clinical experience. Audiological investigation findings for such patients remain equivocal. Recovery can be spontaneous during the postpartum period. In patients who require medical treatment, a dextran 40 infusion can be employed. There remains scope for further research, in the form of larger studies, to ascertain the best management option for this clinical problem.

Hearing loss is a prevalent condition with a significant impact on individuals' quality of life. However, comprehensive studies investigating the differential gene expression and regulatory mechanisms associated with hearing loss are lacking, particularly in the context of diverse patient samples. In this study, we integrated data from 10 patients across different regions, age groups, and genders, with their data retrieved from a public transcriptome database, to explore the molecular basis of hearing loss.

Speechreading-gathering speech information from talkers' faces-supports speech perception when speech acoustics are degraded. Benefitting from speechreading, however, requires listeners to visually fixate talkers during face-to-face interactions. The purpose of this study is to test the hypothesis that preschool-aged children allocate their eye gaze to a talker when speech acoustics are degraded.

Autosomal dominant deafness-15 which is caused by mutation in the POU4F3 gene, has been reported with a wide degree of clinical heterogeneity, even between intrafamilial members. However, the reason is still elusive. In this study, A four-generation Chinese family with 11 patients manifesting late-onset progressive non-syndromic hearing loss was recruited.

Background: Congenital disorders of glycosylation (CDG) are a group of metabolic disorders related to dysfunctional glycoprotein and glycolipid biosynthesis. ALG11-related CDG is a rare member of this group, characterized by severe neurodevelopmental impairment, progressive microcephaly, sensorineural hearing loss, and epilepsy. The objective of this report is to provide an update on the phenotype and brain magnetic resonance imaging (MRI) at age seven years for a patient initially described in early infancy with fetal brain disruption sequence.

Background: Griscelli syndrome (GS) is a rare genetic disorder characterized by oculocutaneous albinism and variable immune dysfunction. Among three distinct types of GS, occurring due to different genetic mutations; GS type 1 presents with neurological manifestations, hemophagocytic lymphohistiocytosis (HLH) generally develops in GS type 2, and GS type 3 primarily exhibits oculocutaneous albinism. HLH, a life-threatening condition with excessive immune activation, may occur secondary to various triggers, including infections, and develop in different tissues, as well as in the testis, similar to Erdheim-Chester disease.
