Hydronephrosis caused by kidney malrotation.

Hydronephrosis associated with kidney malrotation can be a surgical challenge. We present the case of a 3.5 y.o.-boy presenting with left pyelo-ureteric obstruction caused by kidney hyperrotation (270°) resulting in recurring urinary tract infection. After complete radiological work-up, we opted for a primary laparoscopic ureterocalicostomy, which allowed for complete resolution of the pelvic dilatation. Kidney malrotation can present with a wide variation in anatomic features. Radiological work-up is the cornerstone of surgical strategy planning. Laparoscopic ureterocalicostomy is a useful primary option in unusual anatomical situations.

Morel-Lavallée Lesion of the Knee in the Young Athlete: About 2 Cases After Sports Trauma.

BACKGROUND: Differential diagnosis of soft tissue swelling on exposed body parts in the young athlete is large and mostly includes benign self-limiting conditions, once underlying lesion to the bone, the cartilage, and the ligaments is excluded. Morel-Lavallée lesion represents a rare soft tissue injury requiring prompt intervention to ensure favorable outcome. CASES: A 10-year-old boy presented with 2-week-old swelling of the medial side of the knee without recent traumatic event. Unawareness of Morel-Lavallée lesion in the differential diagnosis led to delayed diagnosis and treatment. A 16-year-old boy came to our pediatric tertiary care center with a similar presentation and history. Timely intervention allowed for favorable outcome and early return to play. CONCLUSIONS: Morel-Lavallée lesion is a rare entity in the pediatric population, although underreporting due to unfamiliarity with the diagnosis is highly probable. Raising awareness among professionals in charge of young athletes should allow for better reporting as well as for elaboration of a standardized treatment plan, including rapid intervention and early return to play.

Epidemiology of Pediatric Upper Extremity Fractures in a Tertiary Care Center in Switzerland.

OBJECTIVE: Fractures in children are common and account for 10% to 25% of injuries in children with considerable effects on activity restriction and subsequent high socioeconomically impact. Eighty percent of all fractures in children occur at the upper extremity. The article investigates the epidemiology and fracture pattern of the upper extremity within a pediatric population consulting a tertiary referral hospital in Switzerland. METHODS: Study population included all patients younger than 18 years presenting with an upper extremity fracture. Recorded data were age, sex, side, season of the year, mechanism, type of fracture, and applied treatment. RESULTS: Fractures of the upper extremities represented 76% with a mean age of 9 years and 7 months. Compared with girls, boys had a risk ratio of 1.35 (1.14-1.6) of having a traumatic injury. The radius, with 298 fractures (37%), was the most injured bone. Overall simple fall from his or her height and soccer represented the main injury mechanisms accounting for 26% and 9%, respectively. Eighty-six percent of fractures were treated by cast with or without closed reduction, 11% (92) by closed reduction and pinning or elastic stable intramedullary, and only 3% of fractures were treated by open reduction and internal fixation. CONCLUSIONS: Eighty-six percent of all fractures could be treated by conservative methods. Only 17% need surgical treatments by orthopedic surgeons. This shows how important it is to train residents in pediatrics for the treatment of upper limb fractures in children.

Bronchopulmonary Sequestration with Morbid Neonatal Pleural Effusion despite Successful Antenatal Treatment.

INTRODUCTION: Bronchopulmonary sequestration (BPS) may cause prenatal pleural effusion (PE) or even hydrops. This case describes a fetus presenting with severe PE, which prenatally waned completely under steroid treatment, yet surprisingly reappeared rapidly after birth, requiring early surgical intervention. CASE DESCRIPTION: A male fetus was diagnosed with left BPS and severe PE. After three courses of prenatal steroid therapy for each recurrence of PE from 27 weeks of gestation, we observed a complete regression of PE prenatally. Yet, PE recurred 18 h after birth and persisted after repeated drainages and steroid therapy. Early total resection of the extralobar BPS was performed and led to complete recovery without recurrence of PE. CONCLUSION: This report underlines that in cases of BPS presenting with prenatal PE needing fetal intervention, even if full regression of PE is observed before birth, there might be a need for surgical excision during the neonatal period.
