Nonpalpable testes: is there a relationship between ultrasonographic and operative findings?

Background: Ultrasonography (US) as a diagnostic tool in the work-up of boys with nonpalpable testes (NPT) is still controversial. Objective: To evaluate the relation between US and operative findings in boys with NPT. Materials and methods: During a 7-year period we saw 135 boys with 152 NPT. All were examined by the referring physician or a paediatric surgeon, underwent US examination, and were then re-examined afterwards by a specialist. Finally, all boys were surgically explored for testicular position. Results: US located 103 NPT (68%), 16 within the abdomen and 87 in the inguinal canal. With knowledge of the US result, 37 testes were palpable on re-examination. The sensitivity of US was 97% for inguinal and 48% for abdominal viable testes. Of the 49 testes (32%) missed by US, 16 were viable in either the abdominal (n=14) or the inguinal (n=2) position. Conclusion: All boys with presumed NPT should be referred to a specialist. US is useful to determine localization of NPT, which facilitates planning the surgical procedure. An inguinal exploration is called for when US identifies the testis in the inguinal canal. Because the sensitivity of US for viable abdominal testes is only 48%, we now always perform laparoscopic exploration when US is negative

Rhabdoid Tumor Mimicking Hemangioma

We report a young boy with a malignant tumor, which remained unrecognized for 8 months because it was assumed to be a hemangioma. The presentation of a rhabdoid tumor mimicking hemangioma is very rare. It was reported only on two earlier occasions. Rhabdoid tumors are one of the most aggressive types of malignancies encountered in pediatric oncology. It is important to recognize that a fast growing vascular lesion in a child will often be a hemangioma, but could also be an aggressive tumor

Factors affecting quality of life of children and adolescents with anorectal malformations or Hirschsprung disease

Objectives: First, to compare the quality of life (QL) and perceived self-competence of children and adolescents with anorectal malformations or Hirschsprung disease with that of reference groups. Second, to identify predictors of QL.Patients and Methods: A total of 491 patients with anorectal malformations or Hirschsprung disease were sent a questionnaire, which assessed QL (mental, physical), disease-specific functioning (defecation-related), perceived self-cornpetence (self-esteem, athletic competencies, school attitude), and demographic characteristics (sex, age). The clinical characteristics (disease severity, presence of congenital anomalies) were extracted from medical records.Results: More than 50% (316, 64%) of patients with anorectal malformations or Hirschsprung disease completed the questionnaire. On average, children and adolescents in both patient groups reported no differences in QL domains compared with the reference groups. However, standard deviations revealed considerable individual variation, indicating the presence of patients with high levels of QL as well as patients with low levels of QL. Children and adolescents in both patient groups reported psychosocial problems in all domains, compared with the reference groups. Females, older patients, and those with a severe form of the disease reported lower levels of perceived selfcompetence and global disease-specific functioning, which in turn predicted QL.Conclusions: Our results should alert clinicians to patients who are at risk for QL problems and may therefore be in need of extra care. Our findings illustrate the importance of both global disease-specific functioning and perceived psychosocial competencies for enhancing the QL of these patients.</p
