RESUMO

STUDY QUESTION: Do pre-pubertal boys with hypospadias have a shorter anogenital distance (AGD) than boys with normal genitalia? SUMMARY ANSWER: AGD is significantly shorter in boys with hypospadias and decreases with the severity of hypospadias. WHAT IS KNOWN ALREADY: Animal studies have shown that androgen disruption and exposure to endocrine disrupting chemicals during a critical time period in early gestation, termed the male programming window (MPW), result in hypospadias and reduced AGD; and the severity of hypospadias correlates with the reduction in AGD. However, this correlation has not been established in humans. STUDY DESIGN, SIZE, DURATION: A prospective descriptive study involving measurement of AGD in pre-pubertal boys (n = 458) presenting to our pediatric urology clinic with hypospadias and normal genitalia was performed over a period of 3 years. PARTICIPANTS/MATERIALS, SETTING, METHODS: AGD was measured in pre-pubertal boys from 5 months to 14 years of age presenting to our clinic with hypospadias (n = 180: four were excluded) and compared with randomly selected boys with normal genitalia (controls, n = 274). Three variants of AGD, from the midpoint of the anus to base of the scrotum (AGD-AS), to the anterior base of penis (AGD-1) and to the posterior base of penis (AGD-2), were measured and assessed for correlation with the severity of hypospadias. Severity of hypospadias was classified as anterior, middle and posterior according to the meatal location. MAIN RESULTS AND THE ROLE OF CHANCE: No significant difference in weight (P = 0.123), age (P = 0.162) or height (P = 0.591) between the two groups was observed. Only AGD-AS was significantly shorter in boys with hypospadias compared with controls (mean ± SD: 40.6 ± 9.7 mm versus 45.6 ± 9.4 mm, P < 0.001). This relation persisted after adjusting AGD for weight, height and age (ß = 0.016, 95% confidence interval: 0.10-0.21; P < 0.001). The Spearman test showed a significant negative correlation for the severity of hypospadias with all the three AGD measures. Analysis of variance between anterior, middle and posterior subgroups showed a significant reduction in mean AGD-AS (P = 0.003) and AGD-2 (P = 0.008). LIMITATIONS, REASONS FOR CAUTION: No data were collected pertaining to in utero exposure to endocrine disrupting chemicals (EDCs) or cigarette smoke, or current diet and environmental exposure to EDCs, which may have influenced the AGD. Family history of genital malformation and use of IVF were not known. There may have been a selection bias as only boys presenting to our clinic were included. WIDER IMPLICATIONS OF THE FINDINGS: The findings suggest that prenatal androgens during early gestation influence development of the male reproductive system and support the existence of a MPW in humans. Of the three AGDs, AGD-AS may be the most reliable biomarker of this in utero androgen action. However, no direct link to any specific exposure leading to shortened AGD in pre-pubertal boys with hypospadias could be determined. Further large scale multi-center studies are needed to understand this association better. STUDY FUNDING/COMPETING INTERESTS: Funding was from the Hypospadias Foundation. No conflicts of interest to disclose.

RESUMO

AIM: Phimosis is a common paediatric urological disorder and often necessitates circumcision. We prospectively evaluated local steroid therapy (LST) as the first choice therapy for such children. METHODS: Two hundred and sixty symptomatic boys up to 15 years of age (mean 34 months) with phimosis were started on betamethasone dipropionate (0.05%) application on gently stretched prepuce twice a day. Follow-up visits were arranged at the end of weeks 1, 2 and 4 and 6 months. Grade of phimosis was objectively graded. RESULTS: Ninety one percent of the boys showed a successful outcome at the end of 4 weeks; 72% responded in first week, further 16% responded in week 2, and only 2.6% achieved alleviation of phimosis on further application of LST beyond 2 weeks. Fourty two (17.8%) boys had a recurrence of phimosis on a long-term follow-up (mean - 25.4 months, range 6-48 months); thus, the long-term success rate was 77%, while 60 (23%) boys underwent surgery. CONCLUSION: Local steroid therapy is safe and successful in alleviating symptomatic tight foreskin in a large majority of children. The response can be seen as early as 1 week; most of the children respond by week 2 and continuing therapy further may not be very effective.

RESUMO

A rare case of transmural dumbbell intrathoracic lipoma with intraspinal extension is reported. Preoperative diagnosis was possible with a computed tomographic scan and fine-needle aspiration cytology. Complete excision was curative. The chest wall defect was repaired with Prolene mesh. Only one similar case has been previously reported in the English literature.

RESUMO

Duplication anomalies of the alimentary tract often present with myriad clinical symptoms and signs. There have been no reports of haemoptysis as the presenting feature and oesophageal duplication cyst is not considered as a cause for haemoptysis. An infant presented with this unusual manifestation. Chest X-ray showed persistent right upper zone haziness and contrast enhanced computed tomographic scan showed a multiloculated mass on the right side of the chest. The cystic mass was excised via a right thoracotomy and dense adhesions were noted with the oesophagus. The postoperative period was uneventful and histopathological examination revealed it to be a duplication cyst with ectopic gastric mucosa. Thus, the diagnosis was made retrospectively.
