Introduction And Objectives: A retrospective study was conducted by collecting microbiological tuberculosis (TB) data in Castile and León during the year 2013 in order to determine the incidence and distribution of TB, and resistance to the tuberculostatic drug, and compare them with the epidemiological data provided by the Department of Epidemiological Surveillance (SIVE).

Material And Methods: Microbiologists of the 14 hospitals of the Castile and León public health network (GRUMICALE) collected epidemiological, microbiological, and management data from the Microbiology laboratories in the community during the year 2013. A single isolate of Mycobacterium tuberculosis complex (MTC) per patient was considered.

Background: Mycobacterium africanum is a cause of tuberculosis (TB) that has mainly been described in Africa, but immigration and travel patterns have contributed to the spread of the disease to other countries.

Methods: We retrospectively reviewed TB cases due to M. africanum during 2000-2010 in seven Spanish hospitals.

A review of the scientific evidence available on the validity of existing sample collection methods for urine culture and analysis in childhood is presented. Few studies evaluating diagnostic tests have analyzed the various available techniques with respect to valid patterns of reference. Except for clean catch midstream urine samples, there are no estimators of validity (sensitivity, specificity, probability quotients) that can be generalized to most of the techniques and that could guide decision making.

Setting: During 1996-2000, a regional anti-tuberculosis drug resistance survey was conducted in Castilla-León, Spain.

Objective: To determine the incidence of drug-resistant tuberculosis (TB) in newly treated human immunodeficiency virus (HIV) negative and HIV-positive TB patients.

Design: Nine hundred and eighty-five Mycobacterium tuberculosis strains isolated from HIV-negative (926) and HIV-positive (59) patients were studied (one strain per patient).

The rhinocerebral mucormycosis is the more common form produced by Rhizopus, a genus of fungi. It's a serious infective disease with high mortality, that needs a precocious medical treatment. Amphotericin B is the choice medical treatment, but liposomal amphotericine B in recent years is a better drug, due to minor renal toxicity and greater tisular diffusion.

Background: To assess the usefulness of an enzyme immuno-assay test for the diagnosis of two familial outbreaks of Fasciola hepatica parasitosis in the Zamora area, where watercress are a normal part of the diet.

Patients And Methods: The microbiological diagnosis of two familial outbreaks of fascioliasis was analyzed, which included the search for eggs in feces by the Kato technique and two serologic tests, one screening test by indirect hemagglutination, and a confirmatory test by enzyme-immunoassay in 12 patients.

Results: Five out of the six seropositive patients had eggs detected in their feces.

Rhinocerebral mucormycosis is a serious infectious disease with a high mortality rate that requires early medical treatment. Liposomal amphotericin B is the medical treatment of choice because of its low renal toxicity and good tissue diffusion. Surgical treatment is necessary, even if all affected areas cannot be reached.

The formulation and elaboration of a correct parenteral nutrition (PN) in infancy requires the use of many parameters, the realization of complicated mathematical calculations, and repeated and individualized adjustments of the final constituents. The use of computer programs in the confection of PN has simplified the whole process, but, to our understanding, the programs being used at the moment lack the flexibility needed to generalize its use in the pediatric age. The aim of this work is to present a new computer program able to make up complete pediatric units of PN by itself, which follow the nutritional requirements and the marketed preparations established for each clinical situation.
