A study on 109 patients with the spinocellular epithelioma of skin in the Hospital K during 1992-1996 was carried out. The results have shown that the spinocellular epithelioma was most common disease among non-melanin skin cancer (38.38%) was increasingly every year. The morbidity rate was increased as increased ages, highest in the ages of 60-69. The patients usually admitted lately to hospital in phases of T3 and T4, with high rate of unique one time relapse in the postoperative first year. Almost cases in grade I, II and III.

The possibility of a central origin should be considered for late-onset concomitant esotropia. Concomitant esotropia has been reported to occur with spinocerebellar ataxia types 1, 2, and 3, but not with other degenerative cerebellar ataxia disorders. We report on a 28-year-old woman with ataxia in whom a detailed ophthalmologic examination revealed concomitant esotropia. She was subsequently diagnosed with dentatorubropallidoluysian atrophy (DRPLA). We suggest that the presence of concomitant esotropia could be used to differentiate DRPLA from other hereditary ataxias.

Corneal endothelial degeneration has been reported in diseases associated with CAG repeat expansion including spinocerebellar ataxia type 1 (SCA1) and dentatorubropallidoluysian atrophy (DRPLA). We report a 35-year-old man who has cerebellar ataxia, myoclonic seizure, dystonia, chorea, mental retardation, and visual disturbance. Detailed ophthalmologic examination showed marked reduction of the corneal endothelial cell density. Genetic analysis revealed the presence of a pathological CAG expansion within the DRPLA gene. We suggest that corneal endothelial degeneration might be one of the signs differentiating DRPLA from other hereditary ataxias.

OBJECTIVE: To explore the clinical and genetic characteristics of a child with spinocerebellar ataxia type 29 (SCA29) due to novel variant of the inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) gene. METHODS: The child was subjected high-throughput sequencing, and candidate variant was verified by Sanger sequencing of his family members. RESULTS: The child was found to harbor a c.800C>T (p.T267M) variant of the ITPR1 gene, which was not found in his parents and their fetus. The variant has occurred in a hotspot of the ITPR1 gene variants and was unreported before in China. Based on his clinical and genetic characteristics, the child was diagnosed with SCA29. CONCLUSION The novel heterozygous c.800C>T (p.T267M) of the ITPR1 gene probably underlay the SCA29 in this child.

BACKGROUND: Spinocerebellar ataxia 6 (SCA6) is an autosomal dominant spinocerebellar degeneration and caused by the expansion of the polymorphic CAG repeat in the human alpha 1A voltage-dependent calcium channel subunit gene. In this study, we report the clinical and molecular genetic characteristics of SCA6 in 2 Korean families. We further describe that SCA6 and Episodic ataxia type 2 are simultaneously developed in same family showing no intergenerational changes of CAG repeat numbers. METHODS: Seventeen members of one family and nine of the other received detailed neurological examination and history taking at least one occasion. After the screening test, molecular diagnostic test by using Zhuchenko's method were performed in 13 patients in one family and 3 in the other, respectively. RESULTS: Normal range of CAG repeat in 92 normal individuals was 8 to 17. In this study, the numbers of CAG repeat in one family was 26 and in another was 23. There were no intergenerational differences in the numbers of CAG repeat. Despite the same number of CAG repeat, the clinical anticipation were found. Only one showed episodic ataxia clinically. CONCLUSIONS: Comparing with other types of SCA, the SCA6 had several remarkable characteristics: 1) very small CAG expansions (21-27 repeats) lead to clinical symptoms and the repeat numbers are relatively stable, 2) clinical anticipation is observed despite the relatively stable repeat on intergenerational transmission. The finidngs that an EA2 and a SCA6 exist in a same family may be suggest that two disease are the same disorder with a high phenotypic variablity.

Patients with dentatorubral-pallidoluysian atrophy occasionally elicit psychosis. So far, one study reported first generation antipsychotics drugs may provide an effective treatment; however, there is no literature on the benefits of second generation antipsychotics. We report on a 44-year-old man with dentatorubral-pallidoluysian atrophy whose psychotic symptoms were effectively treated with olanzapine. Our observation suggests some second generation antipsychotics provide a therapeutic option for ameliorating psychosis in dentatorubral-pallidoluysian atrophy.

Early onset cerebellar ataxia with retained tendon reflexes is distinctive clinical syndrome characterized by progressive cerebellar ataxia of unknown etiology with an onset within the first two decades. This disorder was distinguished from Friedreich's ataxia by the preservation of the deep tendon reflexes. There is 22-year-old male with 13 year history of slowly progressive cerebellar ataxia and dysarthria. His elder brother, also, has milder clinical manifestations, electrophysiological and radiological abnormalities. We experienced two cases of early onset cerebellar ataxia with retained tendon reflexes developed in brothers which was diagnosed by clinical manifestations, electrophysiologic, radiologic studies and report with brief review of related literatures.

BACKGROUND: Trinucleotide repeat (TNR) expanded disorders represent a novel class of human mutations, which are characterized by abnormal elongation of the triplet repeat sequence in the human genome and is caused by heritable DNA instability. The aim of this study is to determine the relative frequency, distribution of alleles, and the clinical manifestation of TNR expanded disorders in Korean patients with progressive ataxia. METHODS: A total of 76 clinical specimens that were suspicous of hereditary cerebellar ataxia were submitted from January 1999 to August 2001 and tested for TNR expanded disorders by PCR analysis. RESULTS: Spinocerebellar ataxia (SCA) type 1 was the most common hereditary ataxia (5.3%), while SCA2, SCA3, SCA6, SCA7, and dentatorubral and pallidoluysian atrophy (DRPLA) represented 2.6%, 3.9%, 2.6%, 2.6%, and 1.3% of progressive ataxia patients, respectively. This result is different from previous reports concerning Caucasian, Chinese and Koreans. CONCLUSIONS: This study may provide the basis for the study of TNR expanded disorders in Korean patients. To elucidate the prevalence and frequencies of mutation types in Koreans, a large scale study should be performed.
