To verify the pyramidalis muscle's frequency (bilaterality, unilaterality, or absence) and morphometry (length of the medial border and width of its origin/base) in a sample of the Brazilian population and the anthropometric influence. ⋯ There were no cases of muscle duplication in one or both sides, as described in some studies. Despite all of its morphometric variation, the pyramidalis muscle maintained its triangular shape with longitudinal fibers in every case. Furthermore, no statistically significant correlation was noted between the muscles' dimensions and person's age, height, weight, or gender.

Randomized Controlled Trial
Anesthesia upstream of the alcoholic lesion point alleviates the pain of alcohol neurolysis for intercostal neuralgia: a prospective randomized clinical trial.
Alcohol for intercostal neuralgia may induce severe injection pain. Although nerve block provided partial pain relief, alcohol might be diluted, and the curative effect decreased when the local anesthetic and alcohol were given at the same point. Therefore, we observed the modified method for intercostal neuralgia, a Two-point method, in which the local anesthetic and alcohol were given at different sites. ⋯ Local anesthetic was given upstream of the point where alcohol was administered, was a feasible and safe method to relieve pain during the operation, and improved the satisfaction of the patients and curative effect.

Comparative Study
Use of strain ultrasound elastography versus fine-needle aspiration cytology for the differential diagnosis of thyroid nodules: a retrospective analysis.
Fine-needle aspiration cytology is the risk stratification tool for thyroid nodules, and ultrasound elastography is not routinely used for the differential diagnosis of thyroid cancer. The current study aimed to compare the diagnostic parameters of ultrasound elastography and fine-needle aspiration cytology, using surgical pathology as the reference standard. ⋯ Strain ultrasound elastography for highly and moderately suspicious nodules facilitated the detection of mildly suspicious, unsuspicious, and benign nodules.

We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. ⋯ This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

To report initial experience from the use of extracorporeal membrane oxygenation (ECMO) in patients who received lung transplantation. ⋯ Lung transplantation requires complex treatment, and ECMO has allowed extending the indications for transplantation and provided adjuvant support in the clinical management of these patients.
