Atypical Kaposi's sarcoma in young inmunocompetent patient.

Kaposi´s sarcoma is a rare tumor associated with human herpes virus 8 (HHV-8) infection. Four main clinical subtypes have been described. This study reports on a form of KS in an HIV negative and immunocompetent middle-aged man.

High prevalence and diversity of HIV-1 non-B genetic forms due to immigration in southern Spain: A phylogeographic approach.

Phylogenetic studies are a valuable tool to understand viral transmission patterns and the role of immigration in HIV-1 spread. We analyzed the spatio-temporal relationship of different HIV-1 non-B subtype variants over time using phylogenetic analysis techniques. We collected 693 pol (PR+RT) sequences that were sampled from 2005 to 2012 from naïve patients in different hospitals in southern Spain.

Phylodynamic and Phylogeographic Profiles of Subtype B HIV-1 Epidemics in South Spain.

Background: Since 1982, HIV-1 epidemics have evolved to different scenarios in terms of transmission routes, subtype distribution and characteristics of transmission clusters. We investigated the evolutionary history of HIV-1 subtype B in south Spain.

Patients & Methods: We studied all newly diagnosed HIV-1 subtype B patients in East Andalusia during the 2005-2012 period.

[Letal endocarditis due to Corynebacterium pseudodiphtheriticum].

We present a case report of a infective endocarditis by Corynebacterium pseudodiphtheriticum in a young patient eight years old with bicuspid aortic valve that led to a severe neurological embolism and death. Corynebacterium pseudodiphtheriticum is part of the nasopharyngeal and skin flora. However, there are cases reported of endocarditis usually associated with immunocompromised patients that mostly presented a poor clinical outcome.

[Study of human immunodeficiency virus transmission chains in Andalusia: analysis from baseline antiretroviral resistance sequences].

Introduction And Objective: Protease and reverse transcriptase HIV-1 sequences provide useful information for patient clinical management, as well as information on resistance to antiretrovirals. The aim of this study is to evaluate transmission events, transmitted drug resistance, and to georeference subtypes among newly diagnosed patients referred to our center.

Methods: A study was conducted on 693 patients diagnosed between 2005 and 2012 in Southern Spain.

Case for diagnosis.

Majocchi's granuloma is a persistent supurative folliculitis, associated with a deep granulomatous reaction induced by dermatophytes. There are two clinical forms of Majocchi's granuloma: the superficial form that appears in healthy individuals after localized trauma; and the nodular form, which occurs in inmunocompromised patients. We present a case of nodular Majocchi's granuloma on the forearm of an immunocompetent patient.
