ABSTRACT
Chromobacterium violaceum is a facultative anaerobic, Gram-negative rod found in different ecosystems, especially tropical and subtropical areas. Human infections are rare, and just a few cases have been reported in literature. In this paper, we present the first non-lethal infection due to Chromobacterium violaceum, in an adult male with polycystic kidney disease in Colombia. Periareolar soft tissue infection was documented with isolation of Chromobacterium violaceum. Clinical manifestations, treatment, and outcome are shown.
ABSTRACT
Pyomyositis commonly presents with fever, muscle pain and abscess formation involving deep soft-tissue compartments. Staphylococcus aureus is the main causative organism and diagnosis is usually established clinically, supported by imaging, but confirmation may be achieved by histopathological examination. Broad-spectrum antibiotic therapy and surgical debridement are the cornerstone of treatment. Its prognosis is good but, as in all soft-tissue infections, it depends on early intervention, directed antibiotics and, if indicated, prompt surgery. In this paper, we describe a case of pelvic pyomyositis complicated with bacteraemia and bilateral septic pulmonary emboli in a young man in Colombia.

Malaria is an acute febrile disease due to Plasmodium species widely distributed in tropical areas of the world and it is a leading cause of death in developing countries. In 2018, 62.141 confirmed cases of malaria were reported in Colombia with P. vivax and Plasmodium falciparum being the causal species. Vectorial transmission is the most common way of acquiring the infection, however it can also occur by blood transfusion, transplacental route and percutaneous exposure. We describe a case of P. vivax infection by needle stick injury in a laboratory technician in Bogotá, Colombia.

Resumen: La enfermedad de Creutzfeldt-Jakob (ECJ) es una patología neurodegenerativa transmisible, producida por una proteína anómala infectante denominada prion. Junto con el kuru, el insomnio familiar fatal y el síndrome de Gerstmann-Stráussler-Scheinker, configura el grupo de las llamadas encefalopatías espongiformes. La ECJ es la forma más común en el ser humano: se calcula que afecta a una persona por cada millón, a nivel mundial, y la mayoría de los pacientes presenta síntomas clásicos de demencia y mioclonías, asociadas a cambios específicos en el electroencefalograma (EEG). Conforme la enfermedad progresa, el cuadro demencial empeora y pueden presentarse síntomas visuales, cerebelosos, piramidales y extrapiramidales. El diagnóstico definitivo se logra demostrando la degeneración espongiforme de las neuronas en histopatología. La ECJ siempre es mortal y no tiene tratamiento específico: cerca del 90% de los pacientes fallece dentro del primer año después del diagnóstico. En este artículo, se reporta el caso de un paciente con ECJ esporádica probable, de acuerdo con los criterios diagnósticos actuales de la OMS y se da a conocer una revisión de la literatura.
Abstract: Creutzfeldt-Jakob disease (CJD) is a transmissible neurodegenerative pathology produced by an infecting abnormal protein called prion. Together with kuru, fatal familial insomnia, and Gerstmann-Stráussler-Scheinker syndrome, it forms the group of so-called spongiform encephalopathies. CJD is the most common form in humans: it is estimated to affect one person per million worldwide and most patients have classic symptoms of dementia and myoclonus, associated with specific changes in the electroencephalogram (EEG). As the disease progresses, the dementia condition worsens and visual, cerebellar, pyramidal, and extrapyramidal symptoms may develop. The final diagnosis is achieved by proving the spongiform degeneration of neurons in the histopathology. CJD is always fatal and has no specific treatment: about 90 % of patients die within the first year of diagnosis. This article reports the case of a patient with probable sporadic CJD, following current who diagnostic criteria, and provides a literature review.
Resumo: A doença de Creutzfeldt-Jakob (DCJ) é uma doença patologia neurodegenerativa transmissível, produzida por uma proteína anormal infectante denominada prion. Juntamente com o kuru, a Insónia familiar fatal e a síndrome de Gerstmann-Stráussler-Scheinker, forma o grupo das chamadas encefalopatias espongiformes. A DCJ é a forma mais comum em humanos: estima-se que ela afete uma em cada um milhão de pessoas em todo o mundo, e a maioria dos pacientes apresenta sintomas clássicos de demência e mioclonia, associados a alterações específicas no eletroencefalograma (EEG). À medida que a doença progride, o quadro de demência piora e podem surgir sintomas visuais, ce-rebelares, piramidais e extrapiramidais. O diagnóstico definitivo é obtido por meio da demonstração da degeneração espongiforme dos neurónios na histopatologia. A dcj é sempre fatal e não possui tratamento específico: cerca de 90% dos pacientes morrem no primeiro ano após o diagnóstico. Neste artigo, é relatado o caso de um paciente com dcj esporádica provável, de acordo com os atuais critérios de diagnóstico da oms, e é apresentada uma revisão da literatura.

Las infecciones oculares por hongos filamentosos han aumentado su incidencia con el pasar de los años. Los traumas corneales, la terapia inmunosupresora y el uso de lentes de contacto han hecho que éstas aumenten su incidencia, pero existe un pequeño porcentaje de paciente que sin ningún factor de riesgo presentan infecciones por estos mohos. En este artículo reportamos dos casos de infección ocular por Fusarium spp. en dos pacientes de 21 y 30 años de edad respectivamente, inmunocompetentes, pertenecientes a las Fuerzas Militares y sin factores de riesgo asociados.
The filamentous fungal eye infections have been increasing in incidence in the last years. Corneal trauma, immunosuppressive therapy and use of contact lenses have increased their incidence, nonetheless a small percentage of patients with no risk factors still present with these mold infections. In this article we report a case of ocular infection by Fusarium spp. in two patients, a 21-year-old and a 30-year-old males. They work with the Military Forces, and were immunocompetent with no risk factors associated to the problem.
As infecções oculares por fungos filamentosos têm aumentado a sua incidência com o passar dos anos. Os traumas da córnea, a terapia imunossupressora e o uso de lentes de contato têm feito que estas aumentem a sua incidência, mas existe uma pequena percentagem de pacientes que semnenhumfator de riscoapresentam infecções por estes bolores. Em este artigo reportamos dois casos de infecção ocular por Fusarium spp. em dois pacientes de 21 e 30 anos de idade respectivamente, imunocompetentes, pertencentes às Forças Militares e semfatores de risco associados.
