The early results of the new operation for pectus excavatum are good in most children. The minimal invasiveness of this method suggests that this procedure is indicated in cases where the defects are only cosmetic.

ObjectiveEstrogen replacement therapy (ERT) for Turner syndrome (TS) is a widely discussed topic; however, the optimal model of ERT for patients with delayed diagnosis and/or initiation of therapy is still unclear, mainly due to insufficient data. We present the results of a prospective observational single-center study in which the efficacy of late-onset puberty induction by one-regimen transdermal ERT in TS girls was evaluated.MethodsThe analysis encompassed 49 TS girls (63.3% with 45,X) with hypergonadotropic hypogonadism in whom unified transdermal ERT protocol was used for puberty induction (first two months 12.5 μg/24 h, thereafter 25.0 μg/24 h until breakthrough bleeding). Clinical visits for examination and therapy modification took place every 3–6 months. Transabdominal pelvic ultrasound examinations were performed at least twice: at the beginning and at the end of follow-up.ResultsThe mean (SD) age at ERT induction was 15.1 (1.3) years. The duration of follow-up was 2.4 (1.1) years. Half of all the patients had at least B2 after 0.57 years, B3 after 1.1 years, B4 after 1.97 years, and menarche after 1.82 years from ERT initiation. With earlier initiation of ERT (≤14 years), B2 (p = 0.059) was achieved faster and B4 (p = 0.018) significantly slower than with the later start of ERT. Thirty-four (94.4%) patients had at least stage B3 at menarche. The karyotype, initial weight, and body mass index had no impact on puberty tempo during ERT. The uterine volume increased significantly during ERT in all the study group (p < 0.0001), and in half of the patients, the increase was at least 12.4-fold. It did not correlate with the duration of treatment (p = 0.84) or the dose of estradiol per kilogram (p = 0.78), nor did it depend on karyotype (p = 0.71) or age at ERT initiation (p = 0.28). There were no differences in ΔhSDS during ERT (p = 0.63) between the two age groups (ERT ≤14 and >14 years).ConclusionThe presented easy-to-use fixed-dose regimen for late-onset puberty induction allowed for a satisfactory rate of achieving subsequent puberty stages and did not influence the growth potential.

Four cases of ureteral triplication in children are described. In one case ureteral triplication was detected incidentally and it was not accompanied by any other pathology of the urinary tract. In the three remaining cases there were pathologies of the urinary system (reflux, obstruction) that demanded surgical treatment. The literature concerning this rare anomaly is reviewed.

On the basis of these results, it was concluded that this population is potentially interested in the use of fetal surgery.
