Acute respiratory distress syndrome (ARDS) is an inflammatory process in the lungs that induces nonhydrostatic protein-rich pulmonary edema. ARDS occurs in roughly half of coronavirus disease 2019 (COVID-19) pneumonia patients, with most of them requiring intensive care. Oxygen saturation, partial pressure of the oxygen, and the fraction of the inspired oxygen are health indicators that may indicate a severe illness necessitating further investigation. As treatments have evolved, a typical pattern of ARDS has likewise evolved. In cases where mechanical ventilation is required, the use of low tidal volumes (<6 ml/kg ideal body weight) and airway pressures (plateau pressure <30 cmH 2 O) was recommended. For patients with moderate/severe ARDS (partial pressure to fractional inspired oxygen ratio <20), prone positioning was recommended for at least 16 hours per day. By contrast, high-frequency oscillation was not recommended. The use of inhaled vasodilators was recommended in patients with persistent hypoxemia despite invasive ventilation and prone position until extracorporeal membrane oxygenation (ECMO). The use of a conservative fluid management strategy was suggested for all patients. Mechanical ventilation with high positive end-expiratory pressure (PEEP) was suggested for patients with ARDS with a ratio of arterial oxygen partial pressure to fractional inspired oxygen (PF) ratios. ECMO was suggested as an adjunct to protective mechanical ventilation for patients with severe ARDS. In the absence of adequate evidence, research recommendations were made for corticosteroids and extracorporeal carbon dioxide removal. While decades of research have been conducted, treatment options for underlying pathologies remain limited, and mechanical ventilation, which removes carbon dioxide from the body, remains essential to achieving better clinical outcomes. This review aims to identify the best ARDS treatments that are currently available.

Japanese encephalitis (JE) continues to be one of the world's most serious infections with no definitive treatment or guidelines. The high morbidity and mortality rate among symptomatic patients warrant the need for further investigation in this regard. Our review focuses on the recent updates on Japanese encephalitis treatment. For that reason, we used an advanced PubMed search with JE and drugs like minocycline, interferon, ribavirin, immunoglobulin, dexamethasone, and acyclovir. All research was done in full papers written in the English language and conducted in humans. This review aims to compare and analyze recent papers regarding JE treatment to guide healthcare providers with the latest information and make evidence-based decisions when presented with this infection. Overall, only minocycline had promising results because one of the two studies showed statistically significant results. The second study showed positive trends in children over 12 years and patients who survived on the first day of hospitalization. The study with intravenous immunoglobulin (IVIG) did not improve the outcomes; however, it increased the levels of neutralizing antibodies. Further study with higher doses may change the outcomes in patients with JE. The other drugs failed to show promising results.

Tuberculosis of the patella complicated with synovitis of the knee joint is a rare complication of tuberculosis. Knee joint tuberculosis is usually caused by pulmonary tuberculosis. A few cases are caused by tuberculosis of the digestive tract or lymphatics. Herein, we present a case of a 27-year-old female who presented with left knee pain and swelling that has been managed conservatively with analgesia and hot fomentation over the last two years without improvement. Initial drainage of pus with synovectomy provided improvement. However, anti-tubercular therapy with arthrotomy provided immediate improvement with the resolution of the pain and swelling, and the patient’s gait recovered back to normal. Careful investigation of a patient with prolonged knee pain and swelling is recommended to avoid misdiagnosis with tuberculosis of the patella as a possible differential.
