Congenital anomalies were identified in 37 of 115 (32%) children and adolescents autopsied with rhabdomyosarcoma. An analysis of sex, age, site, and histology of cases with or without congenital anomalies showed no significant differences. Of the 45 identified anomalies, 14 were considered major and 31 minor. The distribution of the anomalies by system included central nervous (9), genitourinary (10), gastrointestinal (13), and cardiovascular systems (4). Ten patients had complex or miscellaneous anomalies. There was one child with each of the following: Rubinstein-Taybi syndrome, neurofibromatosis, single horseshoe kidney, hemihypertrophy, and Arnold-Chiari malformation. Aniridia was not noted in any case of rhabdomyosarcoma. Individuals with rhabdomyosarcoma have an increased incidence of genitourinary anomalies similar to that in Wilms' tumor. Recent molecular genetic investigations have suggested that rhabdomyosarcoma, Wilms' tumor, and hepatoblastoma share a common pathogenetic mechanism involving chromosome 11. The uniquely increased association of central nervous system anomalies with rhabdomyosarcoma and absence of aniridia would support a different gene locus operative on chromosome 11 for individuals with rhabdomyosarcoma compared to Wilms' tumor. Extensive epidemiologic studies now in progress in patients with rhabdomyosarcoma should provide the incidence of congenital anomalies and potential linkage with prenatal events.

PMID:Congenital anomalies associated with rhabdomyosarcoma: an autopsy study of 115 cases.

The 14 tumors reported in Rubinstein-Taybi syndrome since 1989, when added to the 22 previously reported, are beginning to show a pattern of neural and developmental tumors, especially of the head, which is malformed in the syndrome. Among the neoplasms were 12 of the nervous system: 2 each of oligodendroglioma, medulloblastoma, neuroblastoma, and benign meningioma, a pheochromocytoma, and 3 other benign tumors; 2 of nasopharyngeal rhabdomyosarcoma; and 1 each of leiomyosarcoma, seminoma, and embryonal carcinoma. Among the other benign tumors were an odontoma, a choristoma, a dermoid cyst, and 2 pilomatrixomas.

This review focuses key advances in different pediatric fields that were published in Italian Journal of Pediatrics and in international journals in 2015. Weaning studies continue to show promise for preventing food allergy. New diagnostic tools are available for identifying the allergic origin of allergic-like symptoms. Advances have been reported in obesity, short stature and autoimmune endocrine disorders. New molecules are offered to reduce weight gain and insulin-resistance in obese children. Regional investigations may provide suggestions for preventing short stature. Epidemiological studies have evidenced the high incidence of Graves' disease and Hashimoto's thyroiditis in patients with Down syndrome. Documentation of novel risk factors for celiac disease are of use to develop strategies for prevention in the population at-risk. Diagnostic criteria for non-celiac gluten sensitivity have been reported. Negative effect on nervous system development of the supernumerary X chromosome in Klinefelter syndrome has emerged. Improvements have been made in understanding rare diseases such as Rubinstein-Taybi syndrome. Eltrombopag is an effective therapy for immune trombocytopenia. Children with sickle-cell anemia are at risk for nocturnal enuresis. Invasive diseases caused by Streptococcus pyogenes are still common despite of vaccination. No difference in frequency of antibiotic prescriptions for acute otitis media between before the publication of the national guideline and after has been found. The importance of timing of iron administration in low birth weight infants, the effect of probiotics for preventing necrotising enterocolitis and perspectives for managing jaundice and cholestasis in neonates have been highlighted. New strategies have been developed to reduce the risk for relapse in nephrotic syndrome including prednisolone during upper respiratory infection. Insights into the pathophysiology of cerebral palsy, arterial ischemic stroke and acute encephalitis may drive advances in treatment. Recommendations on breastfeeding and complementary feeding have been updated. Novel treatments for rhabdomyosarcoma should be considered for paediatric patients. Control of risk factors for bronchiolitis and administration of pavilizumab for preventing respiratory syncytial virus infection may reduce hospitalization. Identification of risk factors for hospitalization in children with wheezing can improve the management of this disease. Deletions or mutations in genes encoding proteins for surfactant function may cause diffuse lung disease.
