Acute Cocaine Intoxication: An Approach to Severe Hepatic and Renal Dysfunctions.

Cocaine is a highly addictive substance. Its poisoning can lead to potentially fatal multi-organ dysfunction. We report a case of cocaine overdose with severe multi-organ dysfunction. A healthy 51-year-old man was admitted to the emergency room due to behaviour changes and seizure after inhaling crack. Multiple dysfunctions were developed, with emphasis on liver and kidney dysfunction, due to their severity. The patient had marked hepatic cytolysis with a peak on the third day with alanine aminotransferase (ALT) and aspartate aminotransferase (AST): 7941 and 4453 IU/L, respectively with mild coagulopathy and hyperbilirubinemia. Underwent empirical treatment with acetylcysteine ​​with good clinical response. Also developed anuric AKIN3 acute kidney injury secondary to rhabdomyolysis, requiring treatment with intermittent haemodialysis. The approach to a case with severe multiorgan dysfunction is described, with special emphasis on the use of acetylcysteine. The good evolution of the patient can corroborate the use of this drug as a potential modifier of prognosis.

Multifocal cryptococcal disease in an HIV-infected patient: from diagnostic pursuit to management peculiarities.

Cryptococcosis is a life-threatening fungal infection that affects immunocompromised patients, causing predominantly meningoencephalitis and pneumonia. Lymph node involvement is rare and its identification may not be obvious. We report the case of a patient recently diagnosed with AIDS and previously treated for cryptococcal meningitis who developed multifocal cryptococcal disease despite antifungal treatment, expressed as cervical and mediastinal lymphadenitis and constitutional symptoms. The difficulty of the diagnosis was based on the fact that cryptococcal meningitis was resolved after treatment, and the new manifestations were more typical of other conditions such as tuberculosis and malignancy. Final diagnosis was established after fine-needle aspiration cytology of a lymph node with Cryptococcus identification. Such cases may be difficult to manage, and the possibility of clinical relapse versus cryptococcal immune reconstitution inflammatory syndrome is discussed. Induction therapy was restarted and maintained for a longer period, and the total duration was based on clinical response.
