A thoracal spinal cord teratoma associated with Taussig-Bing anomaly in a newborn.

BACKGROUND: Teratomas are the most common type of childhood germ cell tumor, arising in both ovary and extragonadal locations. From 40% to 50% of the extragonadal teratomas occur in the sacrococcygeal region. Teratomas in the head, neck, brain, mediastinum, abdominal, and spinal cord locations are seen less frequently. Congenital anomalies are observed up to 26% of the cases with teratoma. METHODS: A 2-day-old newborn was admitted to the hospital because of a mass in the interscapular region. She was evaluated for this and other anomalies. The mass was excised totally, and histopathologic evaluation was done. RESULTS: Histopathologic examination of the mass revealed a mature teratoma. In addition, the child had a Taussig-Bing anomaly of the heart. CONCLUSIONS: This appears to be the first report of the association between congenital thoracic spinal cord teratoma and Taussig-Bing anomaly, a specific type of transposition of the great arteries.

Middle cerebral arterial occlusion in a child with osteopetrosis major.

Osteopetrosis major (infantile autosomal recessive type) usually presents with pathological fractures, bone marrow failure and some neurological deficits due to remodelling defect of the bone and narrowed bonny channel of the blood supply. Herein we present a case of osteopetrosis major with neurological deficits not attributed to the narrowed carotid channel of the petrous bone, but due to middle cerebral arterial occlusion 2 cm distal to narrowed channel.

Bone mineral density in children with cerebral palsy.

BACKGROUND: The purpose of the present study was to evaluate the severity of and factors related to osteopenia in children with cerebral palsy (CP). METHODS: Bone mineral density (BMD), calcium (Ca), phosphate (P), alkaline phosphatase (ALP), creatinine, parathyroid hormone (PTH) and 25-hydroxy vitamin D3 (25OHD3) concentrations were determined in 24 children with CP (15 ambulant, nine non-ambulant), aged between 10 months and 12 years (mean (+/-SD) 4.1+/-2.9 years). These vaules were compared with data obtained from a control group. RESULTS: Adjusted mean BMD values were lower in the patient group than in controls (P<0.05). However, there was no difference between BMD values of ambulant and non-ambulant patients. The Ca and P levels of the patient group were significantly higher than those of controls (P<0.05). CONCLUSIONS: The present study showed that BMD was decreased in all children with CP, but to a greater extent in non-ambulant children with CP, and immobilization is the major effective factor on bone mineralization.
