1/7. autopsy case of multiple anomalies with hypoplastic cerebrum, eyes, and endocrine organs, mimicking Micro syndrome.We report an autopsy case of multiple anomalies with severe micrencephaly, bilateral microphthalmos, and hypoplastic endocrine organs. We examined expressions of calcium-binding proteins and hypothalamic and pituitary hormones. A female proband presented with microcephaly, microphthalmia, and psychomotor development delay. At the age of 23 years, she died of cardiorespiratory failure. The endocrine organs demonstrated severe underdevelopment, and the hypoplastic eyeballs had remnant lens, vitreous hemorrhage, and retinal detachment. The brain weighed 260 g; the cerebrum, cerebellum, and brain stem were extremely small; and the tertiary sulci were absent in the cerebral surface. The cross-sectional area of cerebral cortex was reduced to about one third of those in the control, although six-layered lamination, density of pyramidal neurons, and expressions of calcium-binding proteins were comparatively preserved in the cerebral cortex. The third ventricle was hypoplastic, and the bilateral thalami appeared to be fused and the hippocampus was unrolled, whereas the corpus callosum was preserved. In the hypothalamus, the paraventricular nucleus was only identified, and the adenohypophysial somatotrophs were reduced. This may be the first autopsy report of Micro syndrome, which is characterized by microcephaly, brain malformations, optic atrophy, and hypogenitalism, although the case lacked agenesis of the corpus callosum.- - - - - - - - - - ranking = 1keywords = nucleus (Clic here for more details about this article) |
2/7. Beckwith-Wiedemann's syndrome--a report of an autopsied case--.The case presented here is a three-month-old male infant with the Beckwith-Wiedemann's syndrome. Clinically, the patient was characterized by macroglossia, visceromegaly, umbilical hernia, microcephalus and other multiple malformations such as facial flame nevus or ear lobe grooves. The patient died of bronchopneumonia at the age of three months, and an autopsy was performed. Morphological examination revealed adrenal cytomegaly, hyperplasia and hypertrophy of the pancreatic islets, adrenal rest tissue in the right testis or hypertrophy of muscle fibers of the tongue associated with fibrous degenerative change, in addition to bronchopneumonia of the lung, causing his death. On electron microscopical examination, the cytomegalic cell of the adrenal was characteristic of large pleomorphic nucleus and granular substances with high density in the cytoplasm. In this case, thorough histologic search revealed no evidence of tumorous growth in the organs, though the exomphalos-macroglossia-gigantism syndrome has been of interest in its relationship to the occasional occurrence of wilms tumor, adrenal carcinoma or other tumors.- - - - - - - - - - ranking = 1keywords = nucleus (Clic here for more details about this article) |
3/7. A new X-linked syndrome comprising progressive basal ganglion dysfunction, mental and growth retardation, external ophthalmoplegia, postnatal microcephaly and deafness.We report on 4 boys (3 in one family) who have a remarkably constant syndrome of childhood-onset choreoathetosis with later spasticity, postnatal microcephaly, growth and mental retardation, apparent external ophthalmoplegia and varying degrees of deafness. The pedigrees are consistent with X-linked inheritance. The syndrome is compared and contrasted with others comprising basal ganglion dysfunction in childhood. It is concluded that clinically and genetically the condition is unique.- - - - - - - - - - ranking = 436.22002745288keywords = basal ganglion, ganglion (Clic here for more details about this article) |
4/7. Ocular manifestations of the smith-lemli-opitz syndrome.To our knowledge, this article describes the first ocular histopathologic condition of a Smith-Lemli-Opitz proband, despite almost 60 clinical histories that exist in the literature. The sole retinal abnormality in this 1-month-old infant with congenital bilateral cataracts is the extensive dropout of peripheral ganglion axons with incipient optic nerve demyelination. Unusual amorphous cytoplasmic masses that are continuous with photoreceptor discs are prominent aspects of the peripheral subretinal space. The morphological data imply that the localized mitochondrial disintegration is restricted to the corneal endothelium and retinal pigment epithelium and is an important element in the etiology. All children who fail to thrive with vomiting, are mentally deficient, have anteverted nostrils, broad maxillary alveolar ridges, syndactyly of the second and third toes, and ambiguous genitalia should be carefully screened for incipient corneal endothelial changes, mild cataracts, and peripheral retinal changes.- - - - - - - - - - ranking = 23.419708908037keywords = ganglion (Clic here for more details about this article) |
5/7. Hirschsprung megacolon and cleft palate in two sibs.We describe a brother and sister with microcephaly, hypertelorism, short stature, submucous cleft palate, learning problems, and Hirschsprung aganglionic megacolon (HAM). literature review failed to show any previous cases combining the above features.- - - - - - - - - - ranking = 23.419708908037keywords = ganglion (Clic here for more details about this article) |
6/7. Multicore myopathy, microcephaly, aganglionosis, and short stature.Multicore myopathy, classified with the benign congenital myopathies, is manifest clinically as proximal muscle weakness, hypotonia, and delayed motor development. We report an unusual case of multicore myopathy with an expanded clinical syndrome involving the central nervous system, as well as additional congenital malformations. Clinical manifestations included microcephaly, mental retardation, spasticity with hyperreflexia, cerebellar dysfunction, short stature, Hirschsprung's disease, pharyngeal web, and facial dysmorphism.- - - - - - - - - - ranking = 93.678835632149keywords = ganglion (Clic here for more details about this article) |
7/7. Ponto-cerebellar hypoplasia with dystonia: clinico-pathological findings in a sporadic case.microcephaly, absent psychomotor development and dystonic limb movements were the main clinical features of a 3-year-old girl affected by hypoplasia of the pontocerebellar structures. As in the few previously reported cases there are discrepancies between the severity of lesions in the supratentorial and infratentorial compartments. Pathological features such as size reduction of the ventral pons, inferior olive atrophy, dentate nucleus fragmentation, and thinning of the cerebellar cortex suggest an impaired maturation of the involved structures due to a prenatal condition (dated at about 20-28 weeks of gestation). Somatotopic analysis failed to provide conclusive evidence on the primary target of the disease. The affected structures originate from the dorsal rhombencephalic region at about the same gestational age, and their maturation is probably under the control of sets of genes which regulate pattern formation. Early abnormal functioning of such genes might lead to the selected morphogenetical alterations observed in ponto-cerebellar hypoplasia. The normal morphogenetic pattern of the supratentorial structures and the mild lesions observed suggest that their late involvement can be related to a different pathogenetic process.- - - - - - - - - - ranking = 1keywords = nucleus (Clic here for more details about this article) |
