The S/Z ratio: A simple and reliable clinical method of evaluating laryngeal function in patients after intubation
Objectives: 1. To determine the consequences of prolonged intubation on laryngeal function.2. To evaluate simple clinical criteria or tests that could alert the clinician to potential laryngeal pathology requiring ear, ...
Disseminated cryptococcosis in an HIV-negative patient in South Africa: The elusive differential diagnosis
The presence of an opportunistic infection in a patient in sub-Saharan Africa is assumed to be due to underlying immunosuppression from human immunodeficiency virus (HIV) infection. The presence of disseminated cryptococcosis ...
Evaluation of paradoxical TB-associated IRIS with the use of standardized case definitions for resource-limited settings
Objective: Standardized case definitions have recently been proposed by the International Network for the Study of HIV-associated immune reconstitution inflammatory syndrome (INSHI; [IRIS]) for use in resource-limited ...
