Sigmoid volvulus (SV) is extremely uncommon in children and is usually associated with a long-standing history of constipation or pseudo-obstruction. An early diagnosis and management are crucial in order to prevent the appearance of hemorrhagic infarction of the twisted loop, avoiding further complications such as necrosis, perforation and sepsis. In patients with no evidence of peritonitis or ischemic bowel, treatment starts with resuscitation and detorsion of the SV, accomplished by means of sigmoidoscopy and concomitant rectal tube placement. The bowel is then prepared and surgery is undertaken electively during the same hospitalization. We report a detailed review of the literature focusing on technical details, risks and benefits of endoscopic management of SV in childhood.

Anxiety in children undergoing surgery is characterized by feelings of tension, apprehension, nervousness and fear which may manifest differently. Postoperative behavioural changes such as nocturnal enuresis, feeding disorders, apathy, and sleep disturbances may stem from postoperative anxiety. Some Authors pointed out that over 60% of children undergoing surgery are prone to developing behavioural alterations 2 weeks after surgery. Variables such as age, temperament and anxiety both in children and parents are considered predictors of such changes.1 Studies were published describing how psycho-behavioural interventions based on play, learning and entertainment in preparing children for surgery, may reduce preoperative anxiety. Clown-therapy is applied in the most important paediatric facilities and has proved to diminish children's emotional distress and sufferance, as well as consumption of both analgesics and sedatives and to facilitate the achievement of therapeutic goals. The aim of our study was to evaluate the efficacy of clown-therapy during the child's hospital stay, with a view to optimizing treatment and care, preventing behavioural alterations and enhancing the child's overall life quality.

HighlightsWe describe a case of a 3 years old girl, with all features of Herlyn–Werner–Wunderlich syndrome (HWWS) who came to our attention for lower abdominal mass.Only six cases are reported in Literature with early onset of this syndrome under 5 years.The aim of this article is to share our experience and focus the attention on the importance of high level of suspicion of HWWS in neonatal period to early diagnosis and treatment.The possible early presentation of this syndrome should be suspected in all neonates (females) with renal agenesia confirmed postnatally or with prenatal diagnosis.An error of evaluation with planning of removal of mass, that can damage patients in term of chance for a successful reproductive outcome.Our team consider HWWS as differential diagnosis in newborn with prenatal ultrasonography of a cystic mass behind the urinary bladder in the absence of a kidney and plan a pelvic ultrasound (with aim to identify an uterus, normal or dydhelfus, and presence or absence of pelvic mass), an examination under anesthesia and cisto-vaginoscopy, if it is necessary. A high level of suspicion, indeed, is the key to early diagnosis.

Neonatal testicular tumors are rare and should be considered in the differential diagnosis of newborn scrotal masses. Juvenile granulosa cell tumor (JGCT) accounts for about 5% of all prepubertal testis tumors. As a benign neoplasm, radical orchiectomy is sufficient for treatment. We report a case of a newborn with a prenatal diagnosis of scrotal mass. After surgery, the histological diagnosis was juvenile granulosa cell tumor. To date the patient is healthy.
