Article Abstract
PERCHING syndrome is a rare multisystem developmental disorder caused by autosomal recessive (AR) variants (truncating and missense) in the Kelch-like family member 7 gene (KLHL7). We report the first phenotypic and molecular description of PERCHING syndrome in a patient from Central Africa. The patient presented multiple dysmorphic features in addition to neurological, respiratory, gastroenteric, and dysautonomic disorders. Clinical Whole Genome Sequencing in the proband and his mother identified two novel heterozygous variants in the KLHL7 gene, including a maternally inherited intronic variant (NM_001031710.2:c.793 + 5G > C) classified as Variant of Uncertain Significance and a frameshift stop gain variant (NM_001031710.2:c.944delG; p.Ser315ThrfsTer23) of unknown inheritance classified as likely pathogenic. Although the diagnosis was only evoked after genomic testing, the review of published patients suggests that this disease could be clinically recognizable and maybe considered as an encephalopathy. Our report will allow expanding the phenotypic and molecular spectrum of Perching syndrome.

Epidemiology of human metapneumovirus among children with severe or very severe pneumonia in high pneumonia burden settings: the Pneumonia Etiology Research for Child Health (PERCH) study experience.

Article Synopsis
- The study investigated the prevalence and characteristics of human metapneumovirus (hMPV) in children with severe pneumonia across seven African and Asian countries, finding a significant correlation between hMPV and pneumonia cases compared to community controls.
- HMPV was more frequently detected in hospitalized pneumonia cases (6.9%) than in controls (2.3%), with a notable negative association with RSV and a positive association with bacterial infections.
- The majority of hMPV-positive cases were infants under one year, with low mortality rates similar to those of RSV-positive cases, indicating that hMPV pneumonia is challenging to distinguish from RSV pneumonia in clinical settings.

Article Synopsis
- SIRT6 is an important protein that helps control energy use, stress response, and the immune system in living things.
- Researchers studied SIRT6 in the Chinese perch fish and found it was active in many fish tissues, especially when the fish were infected by a virus.
- When SIRT6 levels were increased, it boosted the fish's ability to fight off the virus and prevented the virus from spreading, which could help improve fish farming practices.
Extracorporeal Membrane Oxygenation for Acute Lung Injury in Idiopathic Inflammatory Myopathies-A Potential Lifesaving Intervention.
Rheumatology (Oxford)
May 2024
Division of Rheumatology, Jewish General Hospital, Montreal, Canada.
Objectives: Idiopathic inflammatory myopathies (IIM) can present with acute IIM-related lung injury and respiratory failure, leading to a high mortality risk in intensive care units (ICU). Extracorporeal membrane oxygenation (ECMO) in acute respiratory distress syndrome can be lifesaving. We aimed to report a case series of IIM patients that received ECMO.

Purpose: Antimicrobial misuse contributes to antimicrobial resistance in thoracic transplant (TTx) and mechanical circulatory support (MCS) recipients. This study uses a modified Delphi method to define the expected appropriate antimicrobial prescribing for the common clinical scenarios encountered in TTx and MCS recipients.
Methods: An online questionnaire on managing 10 common infectious disease syndromes was submitted to a multidisciplinary Delphi panel of 25 experts from various disciplines.
PERCHING syndrome caused by variant gene KLHL7 in the first Iranian patient: a case report study.

Neonatal and Children's Health Research Center Golestan University of Medical Sciences, Gorgan, Iran.
Introduction And Importance: PERCHING syndrome is a condition that affects many parts of the body and is caused by genes passed down from both parents. People with this syndrome have delays in their development, unusual facial features, trouble eating and breathing, slow overall growth, weak muscles, and stiff joints.
Case Presentation: The child at the age of 6 months suffered from developmental delay, delayed walking, speech delay, and hypotonia and was referred to the Neurologist.
