Once-daily intrapleural urokinase treatment of complicated parapneumonic effusion in pediatric patients.

In this paper, we describe our experience in the treatment of childhood empyema using urokinase. Patients' ages ranged from 2 to 12 years. Urokinase (dosage: 3,100 IU/kg/day) was diluted in normal saline to produce 1000 IU/ml (maximum dosage 100,000 IU in 100 ml of normal saline). After 2 hours, the clamped catheters were released and connected to water-seal suction at a negative pressure of 10 cm H2O. Pleural irrigations were continued once a day until thoracostomy tube output decreased to less than 10 ml/day (urokinase treatment mean duration: 11.5 days). The complete resolution of the chest effusion was assessed on chest ultrasound scan and radiographs. None of the patients experienced any side effects due to urokinase. It would now seem reasonable to advocate small chest tube thoracostomy and intrapleural urokinase as first-line treatment of pleural empyema in children, with surgery indicated as a secondary intervention.

Transperitoneal laparoscopic adrenalectomy in children.

PURPOSE: The use of a minimally invasive approach for adrenalectomy is poorly defined in pediatric patients, although laparoscopic adrenalectomy is considered a standard procedure in adults. The aim of our study was to describe the safety and feasibility of minimally invasive adrenalectomy in children on the basis of surgical skills and results. MATERIALS AND METHODS: This was a retrospective study of 4 pediatric laparoscopic adrenalectomies performed at our center between 2009 and 2012. All patients underwent transperitoneal lateral laparoscopic adrenalectomies (2 right and 2 left adrenalectomies). RESULTS: Four laparoscopic adrenalectomies were performed. Indications for surgery were neuroblastoma in 2 patients, secernent adrenocortical tumor in 1 patient, and adrenocortical nodular hyperplasia in 1 patient. Patients had a mean age of 87 months (range, 17-156 months) at diagnosis, and the average lesion size was 3.23 cm (range, 0.7-6.4 cm). All laparoscopic adrenalectomies were successful, no conversions to open surgery were required, and no postoperative complications or deaths occurred. The average operating time was 105 minutes (range, 80-130 minutes), blood loss during surgery was minimal, and the mean postoperative hospital stay was 3.75 days (range, 3-5 days). None of the patients showed signs of recurring disease at 15-month follow-up. CONCLUSIONS: Laparoscopic adrenalectomy is a safe, feasible, and reproducible technique offering numerous advantages, including shortening of operating times and postoperative hospital stays, as well as reduction of blood loss and complications. It also provides good visibility and easy access to other organs.

An unusual case of familial adenomatous polyposis with very early symptom occurrence.

We report the clinical case of a patient who showed an "accelerated" form of polyposis, with development of major lesions within the first decade of life. The patient belongs to a familial adenomatous polyposis family-already described in 2001-featured by profuse polyposis at an early age of onset and desmoid tumors in the majority of affected individuals (of both sexes). The family was characterized by an uncommon mutation of the APC gene (c.4391_4700del310insCACCTACTGCTGAAA, previously defined as c.4394ins15del310) consisting in a large deletion of 310 bp at codon 1,464 with duplication of the breakpoint leading to a stop codon at position 1,575. The proband was affected by desmoids tumors at the age of 3 years. In the same year (2004) numerous polyps in the large bowel and a hepatoblastoma developed. After several months new desmoids appeared in the surgical scar. In 2010, at age 9, the patient was operated of total colectomy and endorectal pull-through of the small intestine owing to profuse colorectal adenomatosis. New desmoids developed in 2011 and 2012, and required chemotherapy. Further analysis of the APC gene in the proband revealed several polymorphisms. One of these (c.398A>G) had not been previously reported, nor was present in two other affected members of the family. The clinical case, and the practical implications for therapy, are discussed according to the most recent theories of colorectal cancer development. Long-term treatment with Cox-2 inhibitors might represent a good option for this patient.

Bilateral xanthogranulomatous funiculitis and orchiepididymitis in a 13-year-old adolescent boy.

Xanthogranulomatous orchitis is an extremely rare inflammatory nonneoplastic lesion of the testis. We report a case of a 13-year-old adolescent boy who presented a painless left hemiscrotal swelling. The subsequent ultrasonography and magnetic resonance imaging revealed the presence of abnormal expanding tissue located in both testes and spermatic cord, reaching the internal inguinal ring. Testicular tumor markers were normal. The frozen section examination of the surgical specimen showed only inflammatory tissue and not neoplastic tissue. No orchiectomy was performed. Definitive histopathologic diagnosis was xanthogranulomatous inflammation. To our knowledge, this is the youngest case of xanthogranulomatous orchiepididymitis and funiculitis found in medical literature.

A case of frozen pelvis: primary actinomycosis of urinary bladder in a young boy.

We report a case of urinary bladder actinomycosis in childhood. In children abdominal actinomycosis is rare and unlikely involves the urinary tract, so it is often misdiagnosed. An 7-year-old boy was referred to a secondary level hospital because of abdominal pain and dysuria. Physical examination revealed a left hypochondrial mass. Hypothesizing a pelvic rhabdomyosarcoma, a biopsy with mini-laparotomy access was performed. The first histopathological analysis did not show any malignant cells, and a 14-day antibiotic course was ineffective. Reoperation and biopsy was needed, and the histopathological examination made the diagnosis possible.

Three small testes in left hemiscrotum: a rarer case of polyorchidism.

Polyorchidism is a rare congenital anomaly. A review of literature has yielded about 100 cases. We describe a rarer case of polyorchidism consisting of 3 testes on left hemiscrotum and one normal testis in right hemiscrotum. Diagnosis and management are discussed.
