          Abstract

          Objetivo: Establecer la relación entre el diagnóstico de papilomatosis laríngea juvenil y la infección genital por virus de papiloma humano durante el embarazo. Métodos: Se incluyeron 18 madres de hijos con diagnóstico de papilomatosis laríngea juvenil. Se revisaron las historias de los niños, se realizó anamnesis a las madres buscando antecedentes de infección por virus de papiloma humano durante el embarazo, se practicó evaluación ginecológica actual, citología, vulvoscopia, vaginoscopia, colposcopia y biopsia, de ser necesario. Se tomaron muestras para tipificación viral. Resultados: Hubo 120 casos de papilomatosis laríngea juvenil entre 14 400 pacientes, para una frecuencia de 0,8 %. Entre los pacientes evaluados, predominó el sexo masculino (61,1 %). La edad al momento del diagnóstico fue de 5,7 ± 3,2 años. La enfermedad tenía una mediana de evolución de 2 años. La mediana del número de intervenciones quirúrgicas requeridas por paciente, fue 3. Las manifestaciones clínicas más frecuentes fueron disnea (83,3 %), y disfonía (61,1 %). El genotipo viral en las lesiones laríngeas fue 6 (50 %), 11 (11,1 %) y coinfección 6 y 11 (11,1 %). Se detectó virus de papiloma humano en 5 madres: 3 de alto riesgo y 2 no tipificables. La vía del parto vaginal fue la más frecuente con un 83,3 %. Conclusiones: La papilomatosis laríngea es poco frecuente (0,8 %), genera un cuadro de severidad variable caracterizado por disnea y disfonía, es producido por papilomavirus humano 6 y 11 y se asocia al nacimiento vía vaginal. No hubo correlación entre los tipos virales de madres e hijos.

          Objective: To establish the relationship between the diagnosis of juvenile laryngeal papillomatosis and genital infection with human papilloma virus during pregnancy. Methods: 18 mothers whose children’s diagnoses were juvenile laryngeal papillomatosis were included. The children’s history were checked, the mothers were given the anamnesis procedure looking for human papilloma virus infections during pregnancy, they were given actual gynecologic evaluations, citology, vulvoscopy, vaginoscopy, colposcopy and biopsy where needed. Samples were taken for their viral tipification. Results: There were 120 cases of juvenile laryngeal papillomatosis in 14400 patients, an 0.8% frecuency. Amongst the evaluated patients, most were males (61.1 %). Age at diagnosis was 5.7 ± 3.2 años. The disease had an evolution median time of 2 years. The medical intervention median per patient was 3. The most frecuent clinical manifestations were disnea (83.3 %) and dysphonia (61.1%). The viral genotype on laryngeal lesions was 6 (50%), 11 (11.11 %) and coinfection 6 y 11 (11.1 %). Human papilloma virus was detected in 5 mothers: 3 high risk and 2 non classifiable. Vaginal birth was the most frequent with an 83.3 % rate. Conclusion: Juvenile laryngeal papillomatosis is not very frequent (0.8 %), generates a manifestation of variable severity characterized by dysnea and dysphonia, produced by human papillomavirus 6 and 11 and is associated to vaginal birth. There was no correlation between the viral types of mothers and children.

          Human papillomavirus and cervical cancer.

          Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.
