Cysticercosis mimicking brain neoplasm: MR and CT appearance.

The clinical and radiologic manifestation of neurocysticercosis are varied. Since the introduction of anticysticercal drugs, surgery is only rarely needed in treatment. During the last 2 years, we have encountered two patients with minimal symptomatology whose cerebral CT and magnetic resonance studies demonstrated single lesions consisting of an enhancing nodule surrounded by edema. There was ring enhancement of the nodule in one case and homogeneous enhancement in the other. Surgery was performed in both cases, because the primary consideration was brain tumor.

Differences in job placements between men and women with mental retardation.

Thirty-three men and women with mental retardation living in the New York metropolitan area (USA), who entered a supported employment programme were followed during their first 9 months in competitive employment. Differences in placement outcomes were consistently associated with gender differences. The implications of these findings are discussed in terms of providing employment services to men and women with mental retardation and developmental disabilities.

Osteocartilaginous tumors in the parapharyngeal space arising from bone exostoses.

Three osteocartilaginous tumors that arose from bone stalks were diagnosed by the demonstration, on multiplanar cross-sectional CT and MR images, of the site of stalk attachment to the adjacent mandible (one), skull base (one), and cervical vertebra (one). All three patients presented with signs and symptoms related to mass effect in the parapharyngeal region. Mass effect was more pronounced in the two cases of malignant degeneration (osteosarcoma, chondrosarcoma) than in the single case of benign osteocartilaginous exostosis. Differentiation of benign from malignant osteocartilaginous tumor may be accomplished by appreciating characteristic CT and MR features of the cartilage cap. The differential diagnosis of mass lesions of the parapharyngeal space should include tumors of osteocartilaginous origin.

[Williams and Beuren's syndrome with hypertension and associated renal abnormalities (author's transl)].

The authors presented a case of the Williams and Beuren's syndrome, special by the existence of aorta coarctation, high blood pressure, nephrotic syndrome and renal dysplasia. The Williams-Beuren's syndrome is characterised by the association of facial anomalies, mental retardation and supra-valvular aortic stenosis. The case presented in this study demonstrates: -- the symptomatic diversity of the Williams and Beuren's syndrome; -- and the relationship of this syndrome and severe idiopathic hypercalcemia of the infant. The etiopathogenesis is also discussed.

[Hereditary chronic pancreatitis: an autosomal dominant disease (author's transl)].

We have studied a family in which three people, two child and an adult had hereditary pancreatitis. Hereditary pancreatitis is not a common disease. Abdominal pain is usually the first clinical sign in children. The knowledge of the existence of such a disease and familiarity with the family history of the child allow the pediatrician to make the diagnosis as soon as the first crisis appears. Surgery is thus avoided. Our studies show definitively that this disease is hereditary and is autosomal dominant with a strong decrease of the penetrance.

[Primary severe neonatal hyperparathyroidism. Significance of genetic study and emergency parathyroidectomy].

Primary hyperparathyroidism in the newborn is uncommon. The clinical features as well as histological lesions of the parathyroid glands are quite different from those in the adult. The degree of hypercalcemia and the high frequency of pulmonary complications may threaten the life of the infant. Management is straight forward: early surgical removal and supplementation with calcium and vitamins should be quickly followed by an autograft. In the severe case herein reported, the diagnosis, suggested by family history, was confirmed by a rapid increase in calcemia as well as by very characteristic skeletal lesions.
