Objective: The objective of this study was to establish the genotype-phenotype correlation between karyotype results and the neurological and psychiatric alterations presented in patients with Turner syndrome (TS).
Methods: A retrospective study was conducted on the medical records of 10/140 patients with TS and neurophysiological abnormalities seen at a university hospital in southern Brazil. In addition, a literature review spanning the period from January 1, 2012 to January 1, 2023 was carried out using the PubMed and Virtual Health Library databases.
Results: Our study showed a potential correlation between neurological and psychiatric alterations in patients with TS. These findings are in accordance with those described in literature such as a high prevalence of learning or intellectual disabilities. However, our sample found more seizure episodes than those reported in other studies.
Conclusions: The correlation established could be due to X chromosome dose-effect, as the review suggests that sex chromosome number and hormonal development can be associated with verbal, social, and cognitive skills or impairments.

Cellular and Molecular Effects of the Bruck Syndrome-Associated Mutation in the Gene.
Int J Mol Sci
December 2024
Petersburg Nuclear Physics Institute Named by B.P. Konstantinov of National Research Centre «Kurchatov Institute», 188300 Gatchina, Russia.
Bruck syndrome is a rare autosomal recessive disorder characterized by increased bone fragility and joint contractures similar to those in arthrogryposis and is known to be associated with mutations in the () and () genes. These genes encode endoplasmic reticulum proteins that play an important role in the biosynthesis of type I collagen, which in turn affects the structure and strength of connective tissues and bones in the body. Mutations are associated with disturbances in both the primary collagen chain and its post-translational formation, but the mechanism by which mutations lead to Bruck syndrome phenotypes has not been determined, not only because of the small number of patients who come to the attention of researchers but also because of the lack of disease models.

Molecular and spatial analysis of tertiary lymphoid structures in Sjogren's syndrome.

Tertiary lymphoid structures play important roles in autoimmune and non-autoimmune conditions. While many of the molecular mechanisms involved in tertiary lymphoid structure formation have been identified, the cellular sources and temporal and spatial relationship remain unknown. Here we use combine single-cell RNA-sequencing, spatial transcriptomics and proteomics of minor salivary glands of patients with Sjogren's disease and Sicca Syndrome, with ex-vivo functional studies to construct a cellular and spatial map of key components involved in the formation and function of tertiary lymphoid structures.

Article Synopsis
- Turner syndrome is a genetic disorder caused by the deletion of one X chromosome, leading to diverse karyotypes and phenotypes, but predicting phenotypes remains challenging due to mosaicism.
- A study included 487 Turner women with non-mosaic X chromosome structural rearrangements and found prevalence rates of short stature (72.4%) and ovarian dysfunction (78.8%) linked to specific deletion groups.
- Understanding the specific X chromosome breakpoints is crucial for managing Turner syndrome, particularly for predicting and addressing ovarian dysfunction and future fertility issues.
Bilateral Brachial Neuritis after COVID-19: Case Report.
Rev Bras Ortop (Sao Paulo)
November 2024
Hospital Israelita Albert Einstein, São Paulo, SP, Brasil.
Brachial neuritis, or Parsonage-Turner syndrome, is a rare disease characterized by a sudden, self-limiting pain in the upper limb followed by weakness and atrophy of the shoulder girdle muscles. Bilateral brachial plexus involvement occurs in between 10 and 30% of the patients, but symptoms are usually asymmetrical. The most common etiological factors include infection (25 to 55%) and autoimmune conditions.
