Prevalence of genetic variants in SERPINB2 and PKNOX1 genes in erythema nodosum leprosum patients from southern Brazil.

Introduction: Erythema nodosum leprosum (ENL) is a humoral immune response to Mycobacterium leprae that is characterized by erythematous nodules, and may or may not be associated with systemic symptoms. Thalidomide is the primary treatment for ENL in Brazil, but peripheral neuropathy (PN) is a significant adverse effect. Genetic variants in SERPINB2 and PKNOX1 genes have been implicated in the predisposition to develop thalidomide-induced peripheral neuropathy (TiPN) in patients with multiple myeloma.

The Role of Profunda Femoral Artery Retrograde Puncture in Complex Revascularization of Ileo-Femoral Chronic Total Occlusions.

Introduction: The profunda femoral artery (PFA) puncture is generally fraught with risk of bleeding and iatrogenic damage, leading to possible impaired flow in such a valuable artery. However, the PFA represents a potential retrograde path to the common femoral artery (CFA) due to its usual good size and convenient location. Since endovascular treatment of the CFA and its bifurcation is gaining popularity, this study intends to report the use of PFA access in complex revascularizations.

Brazilian guidelines for the pharmacological treatment of the pulmonary symptoms of cystic fibrosis. Official document of the Sociedade Brasileira de Pneumologia e Tisiologia (SBPT, Brazilian Thoracic Association).

Cystic fibrosis (CF) is a genetic disease that results in dysfunction of the CF transmembrane conductance regulator (CFTR) protein, which is a chloride and bicarbonate channel expressed in the apical portion of epithelial cells of various organs. Dysfunction of that protein results in diverse clinical manifestations, primarily involving the respiratory and gastrointestinal systems, impairing quality of life and reducing life expectancy. Although CF is still an incurable pathology, the therapeutic and prognostic perspectives are now totally different and much more favorable.

2022 Brazilian Thoracic Association recommendations for long-term home oxygen therapy.

Some chronic respiratory diseases can cause hypoxemia and, in such cases, long-term home oxygen therapy (LTOT) is indicated as a treatment option primarily to improve patient quality of life and life expectancy. Home oxygen has been used for more than 70 years, and support for LTOT is based on two studies from the 1980s that demonstrated that oxygen use improves survival in patients with COPD. There is evidence that LTOT has other beneficial effects such as improved cognitive function, improved exercise capacity, and reduced hospitalizations.
