Article Synopsis
  • In utero exposure to maternal antibodies against fetal acetylcholine receptors can cause severe conditions like arthrogryposis multiplex congenita (AMC) and the milder fetal acetylcholine receptor inactivation syndrome (FARIS), but the full impact remains unclear.
  • A study of 46 cases reveals that many affected mothers did not have prior diagnoses of myasthenia gravis, suggesting underreporting and missed preventative measures.
  • Among the findings, significant long-term effects in surviving infants included various physical weaknesses, respiratory issues, and unexpected conditions like hearing loss; treatment with oral salbutamol showed promising improvement in symptoms for many children.

Article Synopsis
  • The study aimed to assess the prevalence, clinical features, and genetic factors of mitochondrial diseases (MD) in Hong Kong by analyzing data from public hospitals from 1985 to 2020.
  • A total of 119 MD patients were reviewed, revealing a prevalence rate of 1.02 cases per 100,000 people, with neurological issues being the most common symptoms and a 37% mortality rate within the cohort.
  • The study highlights the predominance of pathogenic variants in the mitochondrial genome and serves as a foundational step towards creating a local MD registry for further research.

Introduction: Biliary Atresia (BA) requires prompt diagnosis and surgical intervention to optimize its outcome. The aim of this study was to evaluate the accuracy of EHIDA in distinguishing between BA and other causes of cholestatic jaundice.

Methods: This was a retrospective study of all patients who underwent EHIDA in a tertiary center from 1997 to 2019.

Background: Developmental and epileptic encephalopathy 9 (DEE9, MIM #300088) is an early onset seizure disorder associated with cognitive impairment and behavioral disturbances. It is caused by mutation in protocadherin 19 with an unusual X-linked inheritance selectively involving heterozygous females or mosaic hemizygous males, while hemizygous males are unaffected. Cellular interference was the postulated mechanism underlying the unusual inheritance pattern.

Background: Dengue infection is the most common mosquito-borne viral disease worldwide, but no suitable antiviral drugs are available. We tested the α-glucosidase inhibitor celgosivir as a treatment for acute dengue fever.

Methods: To establish eligibility for inclusion in a phase 1b, randomised, double-blind, placebo-controlled, proof-of-concept trial, individuals aged 21-65 years who had had a fever (≥38°C) for less than 48 h, met at least two criteria indicating probable dengue infection, and had a positive result on a dengue point-of-care test kit or PCR assay were referred for screening at a centre in Singapore between July 30, 2012, and March 4, 2013.

Epigallocatechin-3-gallate (EGCG) is the major and most potent polyphenol compound of green tea that has been shown to have anticancer effects against various types of cancers. In this study, in addition to the EGCG compound, a synthetic derivative, the peracetate of EGCG (EGCG-P), was used to investigate the inhibitory effects on growth of androgen-independent prostate cancer in vivo. The advantage of EGCG-P is that it may act as a prodrug, leading to higher bioavailability than EGCG itself.

Objective: Previous reports have documented the benefits of exercise on the well-being of renal patients. However, fewer than 50% of our end-stage renal disease (ESRD) patients engage in regular exercise. To promote exercise, we implemented a home-based exercise program.

Background: We performed a prospective, randomized, controlled, multicenter study on the use of two double-bag disconnect systems: Stay-Safe (SS; Fresenius Deutschland GmbH2) and Ultrabag (UB; Baxter Healthcare, Deerfield, IL) to assess the ease of handling, peritonitis rate, exit-site infection rate, and clinical outcome.

Methods: We enrolled 110 new continuous ambulatory peritoneal dialysis (CAPD) patients; 55 patients were randomized to SS treatment, and 55 patients, to UB treatment.

Results: Patients using the UB and SS systems were followed up for 946 and 846 patient-months, respectively.
