A Rare Case of Cocaine-Induced Muscle Hematoma Followed by Rhabdomyolysis in Association With Acute Kidney Injury and Severe Transaminitis.

Cocaine use can result in a few infrequent complications, among which is localized hematoma. As far as we know, there are very few cases reporting cocaine-induced non-traumatic muscle hematoma complicated by severe transaminitis and rhabdomyolysis. Here we present a patient who developed a significant lower extremity muscle hematoma secondary to inhalational cocaine use. We are reporting this case to bring to light this rare and unusual complication of cocaine use. With recreational use of this drug being so prominent in the patient population, early recognition of this complication can help expedite treatment and reduce the severity of end-organ damage.

[Viral conjunctivitis as the first sign of COVID-19 infection (clinical observation)]. / Virusnyi kon"yunktivit kak pervyi priznak koronavirusnoi infektsii COVID-19 (klinicheskoe nablyudenie).

The article presents a case of complicated viral conjunctivitis. Conjunctivitis was the initial sign of the new coronavirus infection (COVID-19) in the patient. The disease had a fairly long course and led to symmetrical scarring in the form of partial external symblepharon and dry eye syndrome. Ophthalmologists should be aware about this disease and its complications. Early treatment with corticosteroids in combination with symptomatic therapy can contribute to prevention of the development of conjunctival scarring. In addition to conjunctival scarring, this disease can possibly potentiate the development of keratitis, optic neuritis, and uveitis.
