Tumor cervical por Salmonella Typhimurium como forma de presentación clínica de SIDA en un paciente con infección por VIH / Cervical mass caused by Salmonella Typhimurium as a clinical presentation of AIDS in a HIV-positive patient

Infections due to non-typhi salmonellae (NTS) generally cause a mild and self-limited gastrointestinal disease. However, there have been reports of atypical and severe presentations in immunocompromised patients. We report the case of a male patient who consulted with a cervical mass. He was found to be HIV-positive and Salmonella Typhimurium was isolated in one blood culture and cervical mass tissue culture. We discuss the relevance of infections by NTS in immunodeficient patients because they present with more severe illness than normal population. We emphasize the importance of NTS bacteremia as a marker of underlying immunodeficiency. We present some localized infection sites reported in the literature and their relation with particular diseases. We discuss the future relevance that an early start of antiretroviral therapy (ART) may have in HIV patients with NTS acute bacteremia or focal infections. Because infections by NTS can be severe and highly lethal they must be considered in the differential diagnosis of causative organisms of localized infections and bacteremia in HIV patients.

Las infecciones por Salmonella no-Typhi (SNT) en general se tratan de cuadros gastrointestinales benignos y autolimitados en pacientes sin patología de base. Sin embargo, se han descrito presentaciones atípicas y más graves en pacientes con algún grado de compromiso inmunológico. Presentamos el caso de un paciente de sexo masculino el cual consultó por un tumor cervical de gran tamaño. Se diagnosticó infección por VIH y se aisló Salmonella Typhimurium en un hemocultivo y en un cultivo de tejido de masa cervical. Discutimos la importancia de las infecciones por Salmonella no Typhi en el grupo de pacientes con inmunosupresión debido a que presentan cuadros más graves que la población normal. Destacamos la importancia de la bacteriemia por Salmonella no Typhi como marcadoras de inmunosupresión subyacente. Presentamos algunos sitios de infección focal reportados en la literatura médica y su relación con algunas enfermedades particulares. Nos referimos a la importancia que podría tener en el futuro el inicio precoz de terapia anti-retroviral en pacientes con infección por VIH cursando bacteriemias o infecciones focales por Salmonella no Typhi. Debido a la gravedad y alta mortalidad que pueden presentar las infecciones por Salmonella no Typhi deben considerarse dentro del diagnóstico diferencial de microorganismos causantes de lesiones focales y bacteriemia en pacientes con infección por VIH.

Definición actual de la medicina interna y el internista / A consensus definition of internal medicine and the internist

Internal Medicine is a basic clinical specialty in Medicine, but due to it’s vast field of action it is quite difficult to define. This consensus article analyzes different definitions and proposes a current definition while analyzing several aspects of the specialty along with its strengths and weaknesses. We propose to define Internal Medicine as a clinical specialty devoted to the comprehensive care of adults, from adolescence to senility, particularly the diagnosis and non surgical treatment as well as primary and secondary prevention of their diseases, in hospital or ambulatory settings. We propose to define Internal Medicine as a clinical specialty devoted to the comprehensive care of adults in hospital or ambulatory settings, from adolescence to end of life, in terms of prevention, diagnosis and non-surgical treatments of disease.
