[Neonatal conjunctivitis in a hospital at Gran Buenos Aires. Last 5 years up-date]. / Conjuntivitis neonatal en un hospital del Gran Buenos Aires. Situación de los últimos 5 años.

Neonatal conjunctivitis is one of the most important consultation reasons in the first days of life. Causes may be chemical or infectious. Neonatal conjunctivitis study for common microorganisms and Chlamydia trachomatis is being performed at Posadas Hospital since 1995, in a progressive form. The objective of this study was to know the epidemiological situation in the last five years (1999-2003), and to describe the variations detected between two periods, 1995-1998, and 1999-2003. It was observed no change about C. trachomatis prevalence (8%), during all the time in the population studied. With regard to common microorganisms it was showed a decrease in the second period (36.6%) with respect to the first (52.4%). Likely, the causes may be due to changes about sample collection conditions, or to epidemiological variations. The most frequent microorganisms found were: Staphylococcus aureus 69 (27.6%), Streptococcus pneumoniae 68 (27.2%), and Haemophilus influenzae 64 (25.6%). We consider important to evaluate the kind of ocular secretions at the first consultation, which can lead to a symptomatic treatment that will be corroborated or not, according to microbiological results.

[Atypical presentations of strongyloidiasis: a report of 8 cases]. / Presentaciones atípicas de strongyloidiasis: reporte de ocho casos.

Eight clinical cases of patients with an atypical strongyloidiasis are reported. The clinical notes are reviewed, the nematode is demonstrated by serial coproparasitologic modified Baermann's method and in some cases, the parasite is found by direct test of sputum or enterotest. In all cases, the main factor has been the immunological deficiency being this nutritional, neoplasia, autoimmune disease, immunosuppression therapy, although the most frequent is the moderate to severe, nutritional failure, differing with the foreign literature. All of them had a good clinical evolution using Albendazole in high doses or Ivermectin. It is concluded that systemic strongyloidiasis has a clear physiopathological base in relation to cellular immunodeficiency and this must be carefully search in our patients, where the chronic autoinfection is a frequent clinical status, and there are immersed in some type of immunodeficiency, in our environment this is usually nutritional.
