The Surgical Management of Severe Scoliosis in Immature Patient with a Very Rare Disease Costello Syndrome-Clinical Example and Brief Literature Review.

Costello syndrome (CS) is a rare genetic syndrome in which, due to the occurrence of a mutation in the HRAS gene on chromosome 11 that causes the manifestation, a set of features such as a characteristic appearance, many congenital defects, intellectual disability and a genetic predisposition to cancer, friendly personality, and others can be identified. CS is very rare, with an incidence of ~1/300,000, but it belongs to one of the largest groups of congenital syndromes, called RASopathies, occurring with an incidence of 1/1000 people. Scoliosis and kyphosis, as well as other spinal defects, are common, in 63% and 58% of patients, respectively, and a study conducted among adult patients showed the presence of scoliosis in 75% of patients; there may be excessive lordosis of the lumbar section and inverted curvatures of the spine (lordosis in the thoracic section and kyphosis in the lumbar section).

Pulmonologists' Attitudes and Role in Precision Medicine Biomarker Testing for Non-Small Cell Lung Cancer.

Background: Despite advances in precision medicine for non-small cell lung cancer (NSCLC), biomarker testing for these therapies remains frequently underused, delayed, and inequitable. Pulmonologists often play a critical role in the initial diagnostic steps for patients with lung cancer, and previous data show variability in their knowledge and practices regarding biomarker testing. The purpose of this study is to better understand how pulmonologists view their role in lung cancer care.

Reflexive and voluntary saccadic eye movements as biomarker of Huntington's Disease.

Introduction: Subtle abnormalities in the preclinical stage of Huntington's Disease (HD) can be detected using saccadic eye movement assessment reflecting disease progression. This study was aimed to evaluate abnormalities in saccade parameters in asymptomatic carriers and symptomatic HD patients at various stages of HD.

Material And Methods: The study enrolled 104 participants, including 14 asymptomatic carriers of HTT mutations, 44 symptomatic HD patients, and 46 control subjects.

Genetic characterization of Toxoplasma gondii from human and chicken isolates from Argentina.

This study aimed to determine the nPCR-RFLP genotypes of newly obtained T. gondii isolates from human congenital toxoplasmosis cases in Argentina and to determine their allelic profiles for virulence genes ROP18/ROP5. In addition, the ROP18/ROP5 profiles were also determined for previously characterized T.
