RESUMO

Una red de colaboración entre seis países de Europa, América latina y El Caribe ha iniciado un proyecto para mejorar la comunicación y la diseminación científica en salud pública. El proyecto apunta a fomentar la comunicación científica en aspectos de valor actual y futuro como son la escritura científica y el acceso abierto a la información en salud. El proyecto NECOBELAC (www.necobelac.eu) es auspiciado por la Comunidad Europea (7th Framework Programme) y tiene una duración de tres años. Como un reto, el proyecto reconoce las diferencias socio culturales entre los países que participan y se ocupará de generar redes de instituciones en colaboración estrecha para realizar programas de entrenamiento e intercambio de saberes en producción de información y difusión (incluyendo los aspectos técnicos y éticos). El proyecto NECOBELAC incluye al Istituto Superiore di Sanità (ISS) de Italia, coordinador del mismo, el Consejo Superior de Investigaciones Científicas (CSIC) de España, la Universidad de Nottingham (SHERPA) del Reino Unido, BIREME de Brasil, el Instituto de Salud Pública (ISP) de Colombia y la Universidade de Minho, de Portugal.

A collaboration network involving 6 countries in Europe, Latin-America and the Caribbean has embarked on a project (Network of Collaboration Between Europe and Latin American Caribbean Countries-NECOBELAC; www.necobelac.eu) aimed at improving scientific writing open access and scholarly communication to spread know-how regarding current and future issues and information related to health. The NECOBELAC project is sponsored by the European Community (7th Framework Programme) and will last for 3 years. The project recognises the challenge arising from socio-cultural differences between the participating countries and will deal with generating networks involving institutions working in close collaboration for carrying out training and know-how exchange programmes aimed at producing open access information and spreading it (including technical and ethical aspects). The NECOBELAC project currently involves the Istituto Superiore di Sanità - ISS from Italy (coordinating the project), the Consejo Superior de Investigaciones Científicas (CSIC) from Spain, the University of Nottingham (SHERPA) from the United Kingdom, BIREME from Brazil, the Instituto de Salud Pública (ISP) from Colombia and the Universidade de Minho from Portugal.

RESUMO

INTRODUCTION: Acute peripheral neuropathy represents a medical emergency. The causes of it are diverse and plentiful. The most common cause of acute paralytic peripheral neuropathy is the Guillain-Barré syndrome (GBS). As many as 85% of those affected can be expected to make an excellent recovery. OBJECTIVE: To describe the principal risk factors associated, clinical manifestations, treatment, evolution and complications of 28 cases of Guillain-Barré syndrome (GBS) in the "Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán". METHODS: We search in our computer records all files under diagnostic of GBS, during the last ten years. We found 28 cases that were available to study. RESULTS: Mean age was 37 years old (SD 17.2). Fifteen patients were female (54%) and 13 were male (46%). Nine patients (32%) were preceded by a superior via infection, 5 (18%) by a diarrhea illness and 14 patients had not a predisposing factor. The duration of symptoms before diagnostic has a median of 7 days (2-15). Twenty-six patients (93%) had an ascending paralysis and 18 had paresthesias (64%). The most frequent subtype was acute inflammatory-demyelinating polyneuropathy (AIDP) in 18 patients (64%), acute motor-sensory axonal neuropathy (AMSAN) in 5 (18%), acute motor axonal neuropathy (AMAN) in 3 (11%) and 2 patients (7%) had the Fisher-Miller syndrome. Fifteen patients (54%) developed respiratory involvement requiring mechanical ventilation. Twenty-four patients (86%) had cerebrospinal fluid proteins elevated. Twenty patients (72%) had a total recovery, 6 (21%) had a partial recovery and 2 had not any response (7%). DISCUSSION: GBS is a particularly highstakes illness in that its onset is sudden and paralysis is frequently extreme (requiring assisted respiration), however, as many as 85% of those affected can be expected to make an excellent recovery. In our study the majority of patients (54%) develop respiratory involvement requiring mechanical ventilation but in this group the majority had a favorable outcome (71%).

RESUMO

Bacteroides fragilis is an obligated anaerobic bacillus which forms part of the normal intestinal flora of the colon and is often seen as a common pathogen in intraabdominal infections. It is an infrequent pathogen in cases of meningitis; a review of the literature reports only eight cases of this disease in children, especially in neonates with conditioning factors such as abdominal sepsis, chronic middle ear otitis and atrial-ventricular derivations. A case of a newborn baby girl with lumbosacral myelomeningocele is reported. After the defect was surgically corrected, the wound became infected, the stitches opened, the child began to have fever, became irritable and suffered convulsions. The spinal tap showed changes compatible to bacterial meningitis, the bacteria was grown on Shaedler medium. The child was treated with cefotaxime and amikacin showing no satisfactory improvement. Afterwards, a second spinal tap showed Bacteroides fragilis.
