Vitelline duct pathologies in neonates.

OBJECTIVE: The aim of this study was to review the management of pediatric cases of vitelline duct pathology (VDP) detected surgically or incidentally during the neonatal period and the outcomes. METHODS: The data of newborns who were symptomatic and underwent VDP resection or who were incidentally diagnosed with VDP at a single institution between 1985 and 2015 were retrospectively analyzed in terms of age, sex, clinical features, treatment, perioperative findings, ectopic tissue pathology, and postoperative follow-up information. RESULTS: Among the 36 newborns enrolled in this study, 26 were male and 10 were female (2.6:1). The median weight was 2400 g (range: 800-3090 g). In 16 cases (14 males and 2 females; 7:1) the VDP was surgically repaired. Pathological evaluation indicated that 43% (n=7) of the cases had ectopic gastric mucosa. VDP was incidentally discovered in 12 males and 8 females (1.5:1). VDP was removed in 10 cases (50%) and left intact in others. Ectopic gastric mucosa was observed in 10% of the VDP removal cases. Ectopic gastric tissue was more prevalent in the surgical VDP cases than in the incidentally discovered and VDP removal cases (p<0.05). Male predominance was greater in the surgically repaired cases than in the incidentally discovered cases (p<0.05). One patient whose VDP was discovered incidentally was admitted 3 years later with obstruction due to intussusception caused by Meckel's diverticulum, and 1 patient was admitted with rectal bleeding at 11 years of age. CONCLUSION: Symptomatic VDP in the newborn demonstrates a significant gender difference. Symptomatic cases are more likely to have ectopic gastric tissue than non-symptomatic cases. Incidentally detected cases without removal should be followed closely for future complications.

Unusual Presentation of Duplex Kidneys: Ureteropelvic Junction Obstruction.

Aim. Ureteropelvic junction obstruction (UPJO) is rarely associated with a duplex collecting system. We review this unusual anomaly in terms of presentation, diagnostic evaluation, and surgical management. Method. We retrospectively reviewed the medical records of patients diagnosed with a duplex system with UPJO. Result. Sixteen patients (6 girls, 10 boys) with 18 moieties were treated surgically and four patients were treated conservatively. The median age at surgery was two years (range, 2 months to 7 years). The lower pole and upper moiety were affected in 12 and two kidneys, respectively, and both were affected in two patients. The anomaly was right-sided in 12 moieties and left-sided in six. The duplication was incomplete in seven patients and complete in nine. The mean renal pelvis diameter at the time of surgery was 25.6 (range 11-48 mm) mm by USG. The mean renal function of the involved moiety was 28.3% before surgery. Management included pyelopyelostomy or ureteropyelostomy in six moieties, dismembered pyeloplasty in eight moieties, heminephrectomy in four cases, and simultaneous upper heminephrectomy and lower pole ureteropyelostomy in one patient. Conclusion. There is no standard approach for these patients and treatment should be individualized according to physical presentation, detailed anatomy, and severity of obstruction.

Giant juvenile fibroadenoma.

Juvenile fibroadenoma is a common cause of breast masses seen in adolescents and young women. Giant juvenile fibroadenomas are usually single and unilateral. The etiology is thought to be due to increased levels of estrogen during adolescence, although it is not yet fully understood. Treatment options range from simple excision to sub-cutaneous mastectomy according to the size of the lesion. This article aimed to present a case that was diagnosed with "giant juvenile fibroadenoma".
