1/744. MR and CT imaging in the Dyke-Davidoff-Masson syndrome. Report of three cases and contribution to pathogenesis and differential diagnosis.Cerebral hemiatrophy or Dyke-Davidoff-Masson syndrome is a condition characterized by seizures, facial asymmetry, contralateral hemiplegia or hemiparesis, and mental retardation. These findings are due to cerebral injury that may occur early in life or in utero. The radiological features are unilateral loss of cerebral volume and associated compensatory bone alterations in the calvarium, like thickening, hyperpneumatization of the paranasal sinuses and mastoid cells and elevation of the petrous ridge. The authors describe three cases. Classical findings of the syndrome are present in variable degrees according to the extent of the brain injury. Pathogenesis is commented.- - - - - - - - - - ranking = 1keywords = ridge (Clic here for more details about this article) |
2/744. Schinzel-Giedion syndrome: evidence for a neurodegenerative process.We report on a case of Schinzel-Giedion syndrome in which serial magnetic resonance (MR) brain-imaging studies demonstrated a progressive neurodegenerative process. These findings in addition to "coarse" facial appearance and skeletal abnormality suggest that a progressive metabolic defect underlies this syndrome. However, results of detailed investigations for metabolic disorder were all normal.- - - - - - - - - - ranking = 0.765595463138keywords = process (Clic here for more details about this article) |
3/744. cytomegalovirus associated neonatal pneumonia and Wilson-Mikity syndrome: a causal relationship?lung injury caused by intrauterine inflammation has recently been strongly implicated in the pathogenesis of Wilson-Mikity syndrome (WMS). This article supports this theory by suggesting a causative role of intrauterine cytomegalovirus (CMV) infection for the development of WMS. A male premature infant, born at 33 weeks of gestational age, developed chronic lung disease compatible with WMS and diagnostic evaluation was positive for CMV infection. High-resolution computed tomography scan and lung histology revealed typical features of WMS in association with signs of interstitial pneumonia. CMV was found in urine, breastmilk, bronchoalveolar lavage material and lung tissue from open lung biopsy. Follow-up after treatment with ganciclovir and steroids showed resolving lung disease at the age of 6, 10 and 16 months, with lung function signs of mild obstruction. Assuming that a chance coexistence of cytomegalovirus pneumonia and Wilson-Mikity syndrome is rather unlikely, it is possible that intrauterine cytomegalovirus infection caused a pattern of lung injury consistent with Wilson-Mikity syndrome. Further cases of Wilson-Mikity syndrome should be investigated as to a possible role of congenital infection.- - - - - - - - - - ranking = 0.88349030440813keywords = alveolar (Clic here for more details about this article) |
4/744. Rare dental abnormalities seen in oculo-facio-cardio-dental (OFCD) syndrome: three new cases and review of nine patients.Oculo-facio-cardio-dental syndrome is a very rare condition. So far, only nine cases have been documented. We report on three additional female patients representing the same entity. The clinical findings were: congenital cataract, microphthalmia/microcornea, secondary glaucoma, vision impairment, ptosis, long narrow face, high nasal bridge, broad nasal tip with separated cartilages, long philtrum, cleft palate, atrial septal defect, ventricular septal defect, and skeletal anomalies. The following dental abnormalities were found: radiculomegaly, delayed dentition, oligodontia, root dilacerations (extension), and malocclusion. For the first time, fusion of teeth and hyperdontia of permanent upper teeth were seen. In addition, structural and morphological dental changes were noted. These findings expand the clinical spectrum of the syndrome.- - - - - - - - - - ranking = 1keywords = ridge (Clic here for more details about this article) |
5/744. Progressive ponto-bulbar palsy with deafness. A clinico-pathological study.Progressive ponto-bulbar palsy with deafness is a rare disease. It seems to be an abiotrophic process with autosomal recessive inheritance in most instances. Only one autopsy case had been briefly described (Lelong et al., 1941). The clinical features and the pathological findings of a new case are reported. The structures primarily involved are the grey matter of the brain stem and the spinal cord, including to some extent the optic tracts and most of the fiber tracts in the brain stem with exception of the pyramidal tracts.- - - - - - - - - - ranking = 0.1531190926276keywords = process (Clic here for more details about this article) |
6/744. McCune-Albright syndrome: clinical and molecular evidence of mosaicism in an unusual giant patient.Molecular genetics recently uncovered the mystery of the protean picture of McCune-Albright syndrome by identification of the somatic gain of function mutations in the GNAS1 gene. Here we present an adult patient with fibrous dysplasia and an endocrinopathy resulting in unusual giant height. The clinical diagnosis in the patient could be confirmed by molecular investigations in tissues involved in the process of fibrous dysplasia.- - - - - - - - - - ranking = 0.1531190926276keywords = process (Clic here for more details about this article) |
7/744. Hereditary nephritis, deafness and abnormal thrombopoiesis. Study of a new kindred.A fourth kindred displaying the triad of hereditary nephritis, deafness and thrombocytopenia with giant platelets is described. Renal involvement, a common cause of death amongst afflicted subjects, appears to have a better prognosis in the affected members of this family. Although the electron microscopic appearance of the megakaryocytes in the present case appears similar to that in previously reported cases, we suggest that the "giant" platelets may result from a degenerative process of megakaryocytes leading to nuclear regression and cytoplasmic fragmentation, rather than the usual blebbing process.- - - - - - - - - - ranking = 0.3062381852552keywords = process (Clic here for more details about this article) |
8/744. Germline hMSH2 and differential somatic mutations in patients with Turcot's syndrome.Turcot's syndrome is characterized clinically by the occurrence of primary brain tumor and colorectal tumor and has in previous reports been shown to be associated with germline mutations in the genes APC, hMLH1, and hPMS2. Here we describe three patients with Turcot's syndrome, each having colorectal adenocarcinoma and malignant glioma. All the colorectal and brain tumors from these patients showed replication errors in most of the microsatellite loci investigated. Search for underlying germline mutations in the nucleotide mismatch repair genes revealed three different hMSH2 mutations. All colorectal tumors showed a frameshift in the A(10) tract in the coding sequence of the transforming growth factor beta type II receptor (TGFBRII) gene, but no such change was detected in any of the brain tumors. frameshift mutation in the BAX gene was found in one colon carcinoma and mutations in insulin-like growth factor type II receptor (IGFIIR) gene in one glioma. Our data have broadened the possible mutation spectrum of patients with Turcot's syndrome. The difference in the mutation spectrum of TGFBRII, BAX, and IGFIIR between brain and colorectal tumors in these individuals suggests that the mutator phenotype may target different pathogenic pathways in the oncogenic process of the two organs.- - - - - - - - - - ranking = 0.1531190926276keywords = process (Clic here for more details about this article) |
9/744. association of misoprostol, Moebius syndrome and congenital central alveolar hypoventilation.

Pathophysiological aspects of these three diseases are discussed and also the unfavorable prognosis of this association.- - - - - - - - - - ranking = 4.4174515220406keywords = alveolar (Clic here for more details about this article) |
10/744. Focal, steroid responsive myositis causing dropped head syndrome.The dropped head syndrome, which occurs in a variety of neuromuscular disorders, is usually not due to an inflammatory process and generally either self-limited or nonresponsive to therapy. We present an 80-year-old woman who developed progressive neck weakness over a few months due to a focal and restricted inflammatory process involving the neck extensor muscles. She responded dramatically to treatment with immunosuppressive therapy.- - - - - - - - - - ranking = 0.3062381852552keywords = process (Clic here for more details about this article) |
