RESUMO
HIV infection has different clinical presentations. We report a 21-year-old male with longstanding isolated microscopic hematuria attributed to thin glomerular basement membrane disease, who after 15 years of follow-up presented with significant proteinuria. A kidney biopsy was performed, revealing the presence of tubulo-reticular inclusions in the glomerular endothelial cells. This finding led to suspect an HIV infection, which was verified. Antiretroviral therapy, angiotensin-converting enzyme and angiotensin II receptor blockers were prescribed. At 6 years of diagnosis the patient is asymptomatic and has normal kidney function. Microscopic hematuria and low level proteinuria persists.

Granulicatella spp. is a bacteria of the oral cavity, belonging to the nutritionally variant group streptococci, and has been identified in 5% of all bacterial endocarditis. It's an important etiologic species in endocarditis, particularly in the setting of negative blood cultures. Granulicatella is a non-mobile, non- spore forming organism that is both catalase and oxidase negative. The treatment for Granulicatella, is the same for Enterococcus according to the American and European guidelines, however resistance to this treatment has been reported.

Chikungunya fever is an emerging infection in our country due to travelers to endemic areas. It presents acutely with high fever, fatigue, headache, myalgia, skin rash and arthritis, usually as a symmetric polyarthritis compromising the interphalangeal and metacarpophalangeal joints, wrist, elbow, ankle and knee. While most of the symptoms last about a week, arthralgias may become chronic and generate significant functional impairment. Chikungunya has been postulated as a triggering factor for rheumatoid arthritis because of the presence of positive rheumatoid factor. We present the three confirmed cases in Almirante Nef Naval Hospital with the review of the published literature...
La fiebre de Chikungunya es una infección novedosa en nuestro país pues su contagio se produce por viajeros en zonas endémicas. Se presenta generalmente en forma aguda con fiebre alta, astenia, cefalea, mialgia, rash cutaneo y artritis, mayoritariamente como poliartritis simétrica comprometiendo las articulaciones interfalángicas, metacarpofalángicas, muñecas, codos, tobillo y rodillas. Si bien la mayoría de los síntomas duran aproximadamente una semana, las artralgias pueden hacerse crónicas y generar un importante deterioro funcional. Se ha postulado que podría ser un factor gatillante de artritis reumatoide ante la presencia de factor reumatoideo positivo. A continuación se presentan los tres casos confirmados del Hospital Naval Almirante Nef junto a la revisión de la literatura publicada hasta el momento...

Illness presentation in the elderly may be entirely non-specific, with fatigue, loss of function or the presence of geriatric syndromes. We report a 90 years old male consulting in the emergency room for delirium that persisted throughout hospitalization without finding a cause. During the course of hospitalization mild fever appeared and a left knee swelling became apparent. A synovial fluid aspiration showed a leukocyte count of 360 per field with 60% polymorphonuclear cells. The culture was negative. With a presumptive diagnosis of pseudogout, cochicine and celecoxib were started with remission of the confusional state. The patient was discharged 13 days after admission in good conditions.

En los últimos 20 años la incidencia de aspergilosis invasiva ha aumentado entre 5 y 10 veces, presentando una mortalidad que varía desde un 60 a 98 por ciento dependiendo de su localización, enfermedad de base (inmunodepresión), diagnóstico y tratamiento precoz. A pesar que se ha logrado un importante avance en estos dos últimos decenios, aproximadamente un 50 por ciento de los casos se diagnostican post mortem. Se reportan dos casos de aspergilosis (probada y probable) en pacientes inmunodeprimidos de 21 y 44 años respectivamente. El primer caso corresponde a una infección rinosinusal en una paciente con leucemia linfoblástica, con un cuadro clínico caracterizado por aumento de volumen facial izquierdo, compromiso progresivo del estado general y equimosis en región periorbitaria. La endoscopia nasal detectó abundante secreción y tejido friable amarillento sugerente de infección micótica. Las muestras de tejidos enviadas al laboratorio para examen directo y cultivos arrojaron presencia de hifas en la mucosa y crecimiento abundante de Aspergillus flavus. Se inició terapia con itraconazol, cambiándose posteriormente a voriconazol, con respuesta favorable y disminución del dolor y volumen facial. Sin embargo, la paciente fallece al 10º día del ingreso debido a su mal estado general, avance de la falla medular y posterior insuficiencia respiratoria. El segundo caso corresponde a una probable infección pulmonar en una paciente con cáncer de mama en tratamiento quimioterápico. La paciente ingresó con el diagnóstico de neutropenia febril y probable neumonía de etiología bacteriana, fue tratada con antimicrobianos tanto en el hospital comunal como en el de base. Sin embargo, presentó una evolución tórpida, cursando posteriormente con hemoptisis, insuficiencia respiratoria y compromiso de conciencia. Se tomaron muestras de secreción endotraqueal las que fueron enviadas para estudio bacteriológico(TBC) y micológico, además de hemo y urocultivos. Los resultados de los...
In the lately twenty years the incidence of invasive spergillosis has increased five and ten times, causing a mortality rate ranging from 60 to 98 percent, depending on its location, nature of disease (immunodepression), diagnosis and forward treatment. In spite of the fact that there has been a significant progress in this lately period of twenty years, about 50 percent of cases were detected post mortem. Two cases of spergillosis (tested and probable) in 21 and 44 aged immunodepressed patients respectively are herein reported. The first case involves a rhinosinusal infection in a female patient diagnosed with lymphoblastic leukemia, whose clinical symptoms were an increase in the left volume of her face, a progressivecompromise in her overall state of health and ecchymosis in her periorbitary region. Nasal endoscopy revealed abundant secretion and yellowish friable tissues which suggested a mycotic infection. Samples of tissues sent to the lab for direct exam and cultures revealed the presenceof hypha in the mucus and an abundant growth of Aspergillus flavus. The first therapy was with itraconazol, changing later on to voriconazol what resulted in adecrease of pain and face volume. However, the patient dies on the tenth day of her ingress due to her bad state ofhealth, progress in glandular failure and ultimate respiratory insufficiency. The second case involves a probable pulmonary infection in a patient diagnosed with breast cancer and receiving chemotherapy treatment. She was ingressed with a febrile neutropenia and a probable bacterial etiology pneumonia and she was treated with antimicrobial medication both in the community hospital and in the base building. However, she showed a torpid evolution followed furthermore by hemoptisis, respiratory insufficiencyand consciousness compromise. Samples of endotraqueal secretion were taken in order to submit them to bacteriological and mycological (TBC) studies, together with hemo...
