There are few data devoted to the combined assessment of the nutritional and respiratory status of subjects with neuromuscular diseases. The objective was to establish correlations between compartmental nutritional variables and respiratory variables to identify respiratory muscle weakness determinants of patients with amyotrophic lateral sclerosis (ALS) and Duchenne muscular dystrophy (DMD). Cross-sectional study with ALS and DMD patients included in an Institutional Registry of Neuromuscular diseases. ⋯ The CHI% showed the strongest (r > 0.700) positive linear relationship with FVC%, MIP%, MEP%, and PCF% in both ALS and DMD patients (p < 0.001). In this study our patients, BMI did not accurately reflect body composition and underestimated excess fat. This study puts into perspective the relevance of compartmental evaluation to assess respiratory muscle function and establishes that body muscle mass is the most relevant nutritional parameter in relation to respiratory muscle strength.

Acknowledging the rates of endophthalmitis after cataract surgery is very important to understand the seriousness of the disease. Until now, there is no data of this situation in Argentina. The aim of this study was to estimate the incidence of postoperative endophthalmitis after cataract surgery at a tertiary hospital, a medical facility which provides a high degree of subspecialty expertise, in Buenos Aires, Argentina. ⋯ The incidence of endophthalmitis after cataract surgery in this hospital is within the range reported globally. Knowing the regional incidence contributes to decide if new prophylaxis measures are necessary.

COVID-19 develops severe inflammatory responses that can lead to death. It is essential in a pandemic to have accessible instruments to estimate the prognosis of the disease. The lymphocyte-to-C-reactive protein ratio (LCR) is a predictive biomarker studied in oncology, which could have some advantages in COVID-19 patients in the early stages of the disease. Our objective was to estimate the risk of LCR < 100 and mortality in hospitalized patients with COVID-19. ⋯ LPCR <100 in the initial assessment of hospitalized patients with COVID-19 suggests a higher risk of mortality.

A case of a 20-year-old man with multilevel non-contiguous tuberculous spondylitis (cervical, dorsal 6, dorsal 10 and lumbar) is presented. In the context of disseminated tuberculosis in an HIV-negative patient with serious compromise of his general condition and multiple locations of the disease, some of these with fistulas that secreted caseum. The acute paraplegia led, considering the sensory level at dorsal 6, to a first urgent decompression surgery via the posterior approach. ⋯ Subsequently, dislocation of dorsal level 6 was evidenced backwards, compressing the spinal cord and, given the mechanical instability, a third surgical stage was indicated by posterior approach, which included reduction, decompression and fixation, resolving the three levels by posterior approach with bars and screws. The surgical, medical and physiotherapy treatment of this rare form of Pott's disease was successful, with recovery of his mechanical stability and progressive recovery of his neurological status. The surgical, medical and physiotherapy treatment of this rare form of Pott's disease was successful, with recovery of his mechanical stability and progressive recovery of his neurological status.

Since 2018, important changes in the treatment of drug-resistant tuberculosis have been produced in the light of new evidence. The discovery of new anti-tuberculosis drugs, such as bedaquiline and nitroimidazopirane derivatives, as well as the use of repurposed drugs, led to international organizations to recommend new, totally oral, treatment regimens for mono-resistant and multidrug-resistant tuberculosis, leaving aside the prolonged use of injectables, with their inherent toxicity and discomfort. ⋯ In this narrative review, we describe the new definitions, some basic diagnostic aspects, the pharmacological aspects, and the new classification of drugs to be used in the treatment of drug-resistant tuberculosis as well as the currently proposed schemes to treat it available within the Argentinean context. Finally, we include a brief review of ongoing clinical trials on new shortened treatments.
