Article Synopsis
  • Inherited optic neuropathies are the most common mitochondrial diseases, causing the loss of retinal ganglion cells and leading to vision loss due to issues with mitochondrial dynamics.
  • Researchers have linked specific mutations in the MIEF1 gene, which regulates mitochondrial fission, to a late-onset optic neuropathy that initially affects peripheral vision.
  • These MIEF1 mutations do not affect the protein's location or structure but significantly impair mitochondrial network dynamics, emphasizing the crucial role of properly functioning mitochondria in preventing neurodegeneration.

Article Synopsis
  • A total of 52,588 RT-PCR tests for SARS-CoV-2 were conducted in France from March 2 to April 26, 2020, with 6,490 tests in children and 46,098 in adults.
  • The positivity rate for SARS-CoV-2 was 5.9% in children compared to 20.3% in adults, indicating children had a lower rate of infection.
  • The overall risk ratio for adults testing positive compared to children was 3.5, suggesting adults were significantly more likely to test positive throughout the study period.

Objectives: Newborn screening (NBS) for β-thalassemia is based on measuring the expression of the hemoglobin A (HbA) fraction. An absence or very low level of HbA at birth may indicate β-thalassemia. The difficulty is that the HbA fraction at birth is correlated with gestational age (GA) and highly variable between individuals.

Understanding the clinical presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and prognosis in children is a major issue. Children often present mild symptoms, and some severe forms require paediatric intensive care, with in some cases a fatal prognosis. Our aim was to identify the epidemiological characteristics, clinical presentation, and prognosis of children with coronavirus disease 2019 (Covid-19) hospitalized in Paris suburb hospitals.

Background: Current data suggest that COVID-19 is less frequent in children, with a milder course. However, over the past weeks, an increase in the number of children presenting to hospitals in the greater Paris region with a phenotype resembling Kawasaki disease (KD) has led to an alert by the French national health authorities.

Methods: Multicentre compilation of patients with KD in Paris region since April 2020, associated with the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ('Kawa-COVID-19').

Article Synopsis
  • Congenital neutropenias (CNs) are rare genetic disorders that affect how the body produces white blood cells, with some patients not having any known genetic causes.
  • Researchers found a specific gene mutation in 4 cases and studied 66 more patients, discovering 23 had different mutations that lead to serious health issues.
  • Most patients had severe neutropenia from a young age, needed long-term treatment, and some also experienced serious developmental delays or issues with digestion.

Article Synopsis
  • * A total of 13 SCD-related deaths occurred, primarily in SS-genotype patients, with treatment non-compliance being a major risk factor, increasing mortality risk tenfold.
  • * Following the implementation of online guidelines, there was a noticeable improvement in patient care from 2006-2009, including better survival rates, increased TCD coverage, and more timely intensification of therapies.

Background: WHIM syndrome (WS), a rare congenital neutropenia due to mutations of the CXCR4 chemokine receptor, is associated with Human Papillomavirus (HPV)-induced Warts, Hypogammaglobulinemia, bacterial Infections and Myelokathexis. The long term follow up of eight patients highlights the clinical heterogeneity of this disease as well as the main therapeutic approaches and remaining challenges in the light of the recent development of new CXCR4 inhibitors.

Objective: This study aims to describe the natural history of WS based on a French cohort of 8 patients.

Background And Aims: Trachoma is a sight-threatening process triggered by the infection of the conjunctiva with Chlamydiae. Blindness associated with trachoma was reported in Sahelian areas of Cameroon. However, data on the prevalence of this neglected infection in the Far North Region are not available.

Objective: Trachoma (Chlamydia-triggered blinding infection) provoked irreversible visual impairment in about 8 million people in 2011, and the prevalence among children with dirty faces is more than three fold that among children with clean faces. In 250 villages with a high prevalence of trachoma (Kolofata district, Far North Region, Cameroon), the lack of water for facial cleanliness was reported during trachoma awareness campaigns. The objective of this study was to determine if the lack of water was linked with the absence of means to dig wells.

Background: Following an epidemiological study carried out in 2006 showing a high prevalence of blinding trachoma in the Far North Region of Cameroon, a trachoma elimination programme using the SAFE strategy was initiated: three yearly trachoma mass treatments were to be performed.

Methodology/principal Findings: The entire district population (120,000 persons) was treated with azithromycin 1.5% eye drops in February 2008 and January 2009.

Background And Objectives: The two main complications of severe chronic neutropenia are fatal sepsis and myelodysplasia/acute leukemia (MDS/AL). Granulocyte colony-stimulating factor (G-CSF) therapy has significantly reduced the frequency and severity of infections, but its possible influence on the risk of malignancy is not known.

Design And Methods: The French Severe Chronic Neutropenia (SCN) Registry has prospectively collected data since 1994 on 231 patients with various forms of SCN, namely severe congenital neutropenia (n=101), cyclic neutropenia (n=60), glycogen storage disease type Ib (GSDIb) (n=15) and Shwachman-Diamond syndrome (SDS)(n=55).
