RESUMEN
To help address the scarcity of studies on the genetics of Parkinson's disease (PD) in Latin America, we screened 426 Ecuadorians with PD and 80 Colombians (PD = 55, Control = 26) for mutations within several PD-related genes. Among Colombians, we identified several variants within PARKIN and PINK1 genes.

We aimed to replicate a recent study that found a high frequency of the GBA p.K198E mutant in Colombian patients with PD. We identified the p.K198E substitution at a lower frequency in our cohort of Colombians with PD (2.1%), and this was not significantly different than controls (1.7%, P = 0.86) emphasizing the need for larger genetic studies in Latin America.

Rabies encephalitis is a fatal zoonotic viral disease transmitted to humans either by domestic animals like dogs and cats or by wild animals like bats, skunks and raccoons. We present the case of a 25-year-old woman admitted due to behavioral disorders, generalized paresthesiasand acute respiratory deterioration compatible with a respiratory distress syndrome (ARDS) requiring orotracheal intubation, mechanical ventilation and empirical initiation of antibiotic and antiviral therapy. Chest tomography showed pneumomediastinum and changes suggestive of pulmonary infection. In the presence of neurological symptoms, a central nervous system (CNS) infection was suspected and the cerebrospinal fluid showed no pleocytosis, hiperproteinorrachy without glucose consumption; cranial CT scan was normal. During hospitalization, the family reported that the patient was bitten by a cat 30-day prior to the onset of rabies-like symptoms, and the animal was sacrificed. The patient had an unfavorable clinical evolution, with electroencephalographic activity dissociation evidenced by video telemetry. The zoonotic exposure led to the suspected diagnosis of rabies infection. The patient died and the suspected diagnosis was confirmed by histopathology, with presence of Negri bodies on cerebellum Purkinje cells and a positive immunofluorescence test for rabies virus. Both, initial extra-neural manifestations and late reporting of rabies exposure led to delayed diagnosis.
