Conocimiento vaccinal en madres con hijos menores de 5 años / Vaccinal knowledge, in mothers with children under 5 years old

La inmunización, es un mecanismo de defensa que asegura la inmunidad humoral para prevenir enfermedades infantiles graves, y es responsabilidad de los padres. Objetivo: Se plantea indagar el conocimiento vaccinal, en madres con hijos menores de 5 años. Métodos: el estudio se orienta bajo el paradigma cualitativo, enfoque fenomenológico; Los participantes del estudio fueron madres que vacunaron a sus hijos en el centro de salud 20 de febrero, distrito 12D03 Quevedo-Mocache, Ecuador. Para el análisis de los datos se utilizó el soware Atlas ti, vinculando 18 preguntas de reflexión. Resultados: Las categorías emergentes fueron: 1) Las vacunas son muy importantes y necesarias. 2. Vacunaron porque sus hijos crecen sanos y fuertes. 3. para algunas el vacunatorio es agradable y para otras no. 4. Algunas reciben buen trato y atención, otras no. 5. Es insuficiente la información sobre las vacunas. 6. Piden cambios de enfermeras y horarios. Conclusión: el conocimiento vaccinal de las madres, esdeterminante para la protección y la no propagación de enfermedades en sus hijos(AU)

Immunization is a defense mechanism that ensures humoral immunity to prevent serious childhood diseases, and is the responsibility of the parents. Objective: to investigate the vaccine knowledge in mothers with children under 5 years. Methods: the study is oriented under the qualitative paradigm, hermeneutic approach; e study participants were mothers who vaccinated their children in the health center February 20, district 12D03 Quevedo-Mocache, Ecuador. The Atlas ti soware was used to analyze the data, linking 18 reflection questions. Results: The emerging categories were: 1) Vaccines are very important and necessary. 2. They vaccinated because their children grow up healthy and strong. 3. For some the vaccine is nice and for others it is not. 4. Some receive good treatment and attention, others do not. 5. Insufficient information about vaccines. 6. Ask for changes of nurses and schedules. Conclusion: the vaccinal knowledge of the mothers, is decisive for the protection and non-propagation of diseases in their children(AU)

G and P Genotyping of Human Rotavirus Isolated in a University Hospital in Korea: Implications for Nosocomial Infections

To characterize rotavirus G and P genotypes circulating among infants and young children hospitalized with severe diarrhea in a university hospital in Gyeonggi province, Korea, and to examine any association of the genotypes and nosocomial infections, we genotyped 103 isolates of rotavirus by multiplex RT-PCR. In July 2001-June 2002, we found that globally common strains constituted 64.2% (G2P[4] 28.3%, G3P[8] 28.3%, G4P[8] 5.7%, and G1P[8] 1.9%), and the uncommon strain, G4P[6], constituted 26.4%. During July 2002-June 2003, the percentage of common strains decreased to 44.0% (G3P[8] 18.0%, G2P[4] 16.8%, and G1P[8] 10.0%), but G4P[6] increased to 36.0%. G9P[8] was identified in 10.0% of cases, and thus can be considered an emerging strain in Korea. Eight-eight percent of G4P[6] was isolated from newborn babies. Among the 103 patients, there was an evidence of nosocomial rotavirus infection in 23 children (22.3%). Of these, 19 (82.6%) were newborns infected with G4P[6] strains of rotavirus. Most of the children who acquired rotavirus infection nosocomially showed symptoms of diarrhea, vomiting, fever, poor sucking, or dehydration, regardless of the genotype. This study revealed that G4P[6] has been the major genotype causing nosocomial rotavirus infection in our hospital.

Predominant human rotavirus genotype G1P[8] infection in infants and children in Bangkok, Thailand.

Human rotavirus is the major etiologic agent of infantile diarrhea on a worldwide scale. In this study, rotaviruses were detected by reverse-transcription PCR in 42 of 83 stool specimens from children below the age of 3 years with acute diarrhea in Bangkok, Thailand, between November 1998 and August 1999. G and P types of all samples were characterized by restriction endonuclease analysis (REA) and multiplex PCR typing assay, respectively. Strain G1P[8] (76.1%) was the predominant type, followed by G1P[6] (2.4%). Strain G1 combined with mixed P[8]/P[6] was identified in 2 specimens (4.8%) and 7 untypeable G strains (16.7%) were observed. This information on the circulating G and P combinations should be useful for understanding the epidemiology of human rotavirus in Bangkok, Thailand.
