RESUMO

La trombosis venosa pulmonar es una enfermedad potencialmente mortal. Este síndrome puede simular clínicamente un embolismo pulmonar arterial, pero tiene una estrategia de investigación y pronóstico distinto. La trombosis de la vena pulmonar es difícil de diagnosticar clínicamente y, por lo general, requiere una combinación de métodos diagnósticos utilizados convencionalmente. Presentamos la imagen radiológica de una trombosis venosa pulmonar en un varón de 70 años en el que la sospecha clínica inicial fue de tromboembolismo pulmonar arterial


Pulmonary vein thrombosis (PVT) represents a potentially fatal disease. This syndrome may clinically mimic pulmonary embolism but has a different investigation strategy and prognosis. Pulmonary vein thrombosis is difficult to diagnose clinically and usually requires a combination of conventionally used diagnostic modalities. We present the radiological images of a pulmonary vein thrombosis in a 70 year old patient with the initial clinical suspicion of a pulmonary artery thromboembolism

RESUMO

We analysed the impact of the Xpert(®) MTB/RIF molecular test on health-care diagnostic delay among tuberculosis patients. Diagnostic delay was 17.2 days (standard deviation 23.2, median 10 days). Of 128 patients recruited into the study, 60 (47%) were smear-negative; of these, 40 (67%) were Xpert-positive and were started on treatment without culture. The sensitivity of smear microscopy was 53% compared with 82% for Xpert. In smear-negative patients, delay in Xpert-positive and -negative patients was respectively 15.5 ± 13.2 and 25.5 ± 12.5 days (P = 0.002). We conclude that Xpert results were significantly associated with shorter health-care diagnostic delay, particularly in smear-negative patients.

RESUMO

Primary pulmonary botryomycosis, or bacterial pseudomycosis, is an unusual bacterial infection characterised by the formation of eosinophilic granules that resemble those of Actinomyces species infection. The diagnosis of botryomycosis is based on culture of the granules revealing gram-positive cocci or gram-negative bacilli. The bacterial pathogen most frequently found is Staphylococcus aureus. The pathobiology remains unknown. Pulmonary botryomycosis can resemble actinomycosis, tuberculosis or invasive carcinoma. Definitive treatment requires a combination of both surgical debridement and long-term antimicrobial therapy. We present a case of primary pulmonary botryomycosis in an immunocompetent patient.

RESUMO

Lactococcus lactis cremoris is a facultative anaerobic, gram-positive coccus whose natural host is bovine livestock. It may form part of the normal human bacterial flora found in the oropharynx, the gastrointestinal tract and the vagina. This bacterium is essential in the food industry, where it is used in milk fermentation to obtain cheese, yoghurt, etc. Exposure to unpasteurised dairy products has thus been recognised as a risk factor for infection by this organism. It is generally considered to be non-pathogenic, although it appears that pathogenicity may be emerging. We present an atypical case of necrotising pneumonia caused by L. lactis cremoris.
