ABSTRACT

En este studio retrospective se evaluó nuestra experiencia en punciones con aguja fina (P.A.A.F.) con y sin control ecográfico en el Servicio de Ginecología y Patología Mamaria del Hospital Juan A. Fernández. El período analizado comprende entre los años 2000 y 2009. Hemos realizado un total de 3.420 punciones en un total de 2.858 pacientes, de las mismas 2.052 punciones se han realizado sin control ecográfico (tumores palpables) y 1.368 punciones fueron efectuadas con control ecográfico. En todos los casos se contó con la presencia del patólogo para el análisis del material extraído. En 3.420 punciones realizadas por nuestro equipo tuvimos los siguientes resultados: 840 positivos, 2.030 negativos, 75 insuficientes, y 370 material no representativo. Hemos incluido en nuestro material todo tumor palpable al examen clínico, imágenes ecográficas y adenopatías palpables por imaginología. La punción con aguja fina es un instrumento valioso en la conducta terapéutica de los nódulos mamarios. En los casos con imágenes presuntamente benignas la punción con aguja fina con resultado negativo nos permite confirmar los hallazgos por imaginología. Por el contrario, frente a un resultado positivo nos permite planificar la estratégica quirúrgica. Destacamos que la P.A.A.F es un método eficaz de bajo costo y muy pocas complicaciones para la paciente, lo cual nos permite obtener un resultado confiable en el momento. Por tal motivo en nuestra institución la P.A.A.F es la modalidad diagnóstica inicial de elección.

ABSTRACT

Although Japanese encephalitis (JE) virus was isolated from mosquitos in 1974, human JE cases have never been reported in Indonesia in spite of the prevalence of anti-JE antibodies among human and pig populations as well as abundant JE vector mosquitos. In this report, we describe serological diagnosis of JE cases in Bali. Indonesia. using IgM-capture ELISA both on serum and cerebrospinal fluid (CSF) of the patients. In the first series of our investigation (Series 1), we examined serum specimens from 12 patients with clinical diagnosis of viral encephalitis, meningitis or dengue hemorrhagic fever (DHF), and found 2 possible JE cases. In the next series (Series 2), we examined both serum and CSF from encephalitis patients and gave laboratory diagnosis of JE. One of them was suspected to have concomitant or recent infection with dengue virus, probably type 3. These results strongly indicated that JE has been prevalent in Bali, Indonesia.

ABSTRACT

We studied Hymenoptera stings in 72 pest-control operators without any previous systemic reactions to Hymenoptera stings, and investigated their venom-specific IgE levels in serial specimens collected over one year. At the initial evaluation, venom-specific IgE was present in 25 (34.7%) of 72 pest-control operators, and venom-specific IgE titer significantly decreased as the time interval from the last sting increased (p < 0.001). In most cases, venom-specific IgE disappeared less than 3 years after the last sting. On the other hand, the ratio of subjects with positive CAP for venom-specific IgE was significantly increased with an elevation of total serum IgE level (p < 0.001). After the one year follow-up, venom-specific IgE titer in the 25 subjects with positive CAP decreased significantly (p = 0.026). Total serum IgE level modified the decline significantly (p = 0.011), but the time interval from the last sting did not. In elevated total IgE level (>250 IU/ml), the decline of venom-specific IgE tended to be slow.
