ABSTRACT
OBJECTIVE: To research an appropriate estrogen therapy for in the pubertal development in Turner syndrome(TS)achievedbyestradiolvalerate.METHODS: In 57 TS girls of no spontaneous puberty or puberty arrest,we retrospectively studied pubertalstageanduterinedimensionduringtheestrogenreplacementtherapy.Datafrompatientrecordswascollected,described thepubertaldevelopingprocedure,and compared in groups which grouped by estrogen dosage to detect an appropriate dosage andthatcanleadabetterbreastanduterinedevelopment.RESULTS: The median age at start of puberty induction was 15.00 years,witharangeof11.5-21.0 years.(1)Breast development:Breast development to Tanner stage B2 was achieved in 0.29(0.25-0.33)years,stage B3 in 0.75(0.46,1.08)years,stage B4 in 2.20(0.92,3.08)years and B5 in 3.67(1.71,4.44)years.(2)Uterine development:The uterine volume and length in TS girls before treatment was 0.51(0.14,0.86)ml and 1.89(1.23,2.18)cm. We groupedthepatientsofTannerstageB2 ingroupsofestrogendosage≤0.5 mg/dand>0.5 mg/d and the uterine dimension and weightshowednodifference.Whenthepatientsweregroupedasgroupsofdosage<1.0 mg/d and group of dosage≥1.0 mg/d in stageB3,the uterine indexes in lower dosage group were less than group with larger dosage. When they were grouped as groups ofdosage<1.5 mg/d and ≥1.5 mg/d,the uterine volume 6.96(3.15-11.00)ml in lower dosage group was smaller than that in group withlargerdosage.CONCLUSION: During estrogen treatment in TS girls,normal breast development can be achieved. In a clinical setting,the uterine volume and length under pubertal induction developed properly with the breast stages progressing. when the breastdevelopedtostageB2,the uterine development was more dependable on estrogen. We recommend a low daily beginning estrogendosageuntilstageB2,which can be increased gradually after B2 to speed up the uterine development.
ABSTRACT
Introducción. La vulvovaginitis representa el 25% de las consultas en ginecología pediátrica. Objetivo. Evaluar las etiologías de las vulvovaginitis en función de la edad y el estadio de Tanner mamario. Material y métodos. Estudio descriptivo y transversal realizado entre el 1 de enero y el 31 de diciembre de 2011. Se analizaron pacientes con vulvovaginitis en función de dos variables: la edad (GI: 0 a 8,9 años; GII: 9 a 15,9 años y GIII: 16 a 18 años) y el estadio de Tanner mamario (I; II-III; IV-V). Resultados. Se incluyeron 229 pacientes; 78 niñas en GI, 134 en GII y 17 en GIII; en relación con el estadio de Tanner mamario, se agruparon 81 niñas en TI, 36 en TII-III y 112 TIV-V. Shigella y Oxiurus se presentaron con mayor frecuencia a temprana edad. Candida albicans, otras especies de Candida, Gardnerella y Ureaplasma urealyticum se observaron en niñas mayores. Oxiurus predominó en la etapa prepuberal y Candida albicans, en la pospuberal. Conclusiones. En relación con la etiología de las vulvovaginitis, la influencia hormonal es más relevante que la edad cronológica de la paciente.
Introduction. Vulvovaginitis accounts for 25% of all pediatric gynecology consultations. Objective. To assess the etiology of vulvovaginitis based on age and Tanner staging of breast development. Material and Methods. Descriptive, cross-sectional study conducted between January 1st and December 31st, 2011. Patients with vulvovaginitis were assessed based on two outcome measures: age group (GI: 0 to 8.9 years old, GII: 9 to 15.9 years old, and GIII: 16 to 18 years old), and the Tanner staging of breast development (I, II-III, IV-V). Results. Two hundred and twenty-nine patients were included, 78 girls in the GI group, 134 in the GII group, and 17 in the GIII group; 81 girls were classified as TI, 36 as TII-III, and 112 as TIV-V based on Tanner staging. Shigella and Oxyuris were the most commonly found etiologic agents in younger girls. Candida albicans, other Candida species, Gardnerella and Ureaplasma urealyticum were the germs most commonly observed in older patients. Oxyuris was predominant in prepubertal girls, while Candida albicans, in postpubertal girls. Conclusions. Hormonal influence was more relevant than the patient's age in terms of vulvovaginitis etiology.

Para facilitar o diagnóstico clínico e diferencial é de grande importância para os profissionais médicos, principalmente pediatras e ginecologistas, o entendimento e o manejo das alterações mamárias que podem apresentar-se em crianças e adolescentes. Destacamos, principalmente, o desenvolvimento das mamas, que causa preocupação das adolescentes com as alterações do seu crescimento. Investigamos as causas, características e o diagnóstico das mamas assimétricas em crianças e adolescentes.
