1.A case of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy(CADASIL) patient presenting with chorea
Neurology Asia 2012;17(3):247-249
In cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy
(CADASIL), clinical presentation with movement disorders such as dystonia and progressive supranuclear
palsy-phenotype are rarely reported. None of the CADASIL cases, to our knowledge, has been reported
with chorea. Herein, we describe a Korean woman with CADASIL who had presented with chorea.
18F-fl uorodeoxyglucose positron emission tomography (FDG-PET) showed hypometabolism in the
right basal ganglia. We found decreased FDG uptake of the right basal ganglia by SPM analysis.

PURPOSE: p53 gene mutations, one of the most common alterations found in human tumors, has also been detected in gastric carcinoma, and shown to have a crucial and early role in gastric carcinogenesis of intestinal type and mainly associated with tumor progression in the cancer of diffuse type. We tried to investigate the frequency of p53 mutations in 27 gastric carcinomas. MATERIALS AND METHODS: Fresh tumor tissue from a series of gastric carcinoma was screened for p53 mutations by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) with silver staining and confirmed by direct-sequencing in 27 cases of gastric carcinoma. Immunohistochemical method for p53 protein accumulation was also performed in the same cases. RESULTS: Immunohistochemistry revealed 20 of 27 cases of gastric carcinoma, positive for p53. PCR-SSCP analysis of p53 exons 5-8 detected mobility shift in 4 out of 20 p53-positive tumors; three from exon 5 and the other from exon 7, respectively. DNA sequencing of exon 5 showed CGC to CAC point mutation in one of three cases; exon 7, ATC to AAC point mutation. It seemed that there was no correlation between genetic alterations of p53 gene detected by PCR-SSCP and expression of p53 protein by immunohistochemistry. CONCLUSIOAS: Our results suggest that mutations of the p53 gene are rare genetic events in carcinogenesis of gastric carcinomas. There was discrepancy between mutations screened by PCR-SSCP and overexpressions in immunohistochemical staining.

The developement of squamous cell carcinoma from the draining sinus of chronic osteomyelitis has long been recognized as a rare and late complication. The mode of developement of carcinoma at the site of chronic osteomyelitis is not well understood. This, however, is chiefly a disease of middle aged men, and tibia is the most common site. There are two types in this carcinoma; superficial and deep types. In the superficial type obvious presence of fungaiing growth makes diagnosis simple and easily confirmed by biopsy. In the deep type the diagnosis is difficult clinically, but the features most frequently described are an increase in pain and discharge with swelling and hemorrhage. Amputation at the adequate level is the treatment of choice. Three cases of the disease involving one left femur, and two left tibiae are reported with review of literature.

PURPOSE: Intraventricular hemorrhage(IVH) is a major risk factor for neurodevelop- mental handicap in very low birth weight infant. So we carried out to determine the efficacy of indomethacin in reducing the incidence of intraventricular heorrhage in very low birth weight infant. METHODS: A prospective, random trial was carried out to determine the efficacy of indomethacin in preventing intraventricular hemorrhage. A total of 46 infants of less than 1500g birth weight admitted to NICU of IL Sin Christian Hospital from August 1995 to June 1997 were analyzed. Randomly, 23 infants were given indomethacin and 23 infants were not given as control group. Serial cranial ultrasound examination was performed. RESULTS: There were no differences in the birth weight, gestational age, sex, Apgar score, blood pressure, intake and output within the first 3 days between the indornethacin and control groups. Of 23 infants given indomethacin, four had germinal matrix or intraventricular hemorrhage, in comparison with 10 of 23 control infants(P=0.045). CONCLUSION: Prophylactic indomethacin lowers the incidence of IVH in very low birth weight infants.

6.A Case of Neuronal Heterotopia.

Neuronal migrational disorders of the brain represent abnormalities in the formation of the neocortex caused by faulty migration of the subependymal neuroblasts. The neuroblasts normally migrate between the sixth and 15th gestational week and in doing so form the six-layered neocortex. When the migration does not occur in a normal fashion the resultant brain anomalies include lissencephaly, pachygyria, schizencephaly, hemimegalencephaly, heterotopia, and polymicrogyria. Neuronal heterotopia is a collection of nerve cells in abnormal locations as a result of arrest of their radial migration, improper formation, or destruction of the radial glial fiber. We reported a case of neuronal heterotopia with brief review of related literatures.

Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

OBJECTIVE: To assess the effect of fentanyl and midazolam on in vitro fertilization rate and early embryo development in a mouse IVF model. METHODS: Mouse oocytes were exposed in vitro to fentanyl at a concentration of 0(control), 50, 250, 500, 1000, 5000 pg/ml, and midazolam, 0(control), 2.5, 12.5, 25, 50, 250 ng/ml for 30 minutes, washed and inseminated. Thereafter fertilization was assessed. And subsequent in vitro development to the blastocyst stage was monitored daily. RESULTS: Where fertilization occurred, subsequent embryo cleavage and development up to the blastocyst stage was affected significantly by the presence of fentanyl and midazolam solution in the medium(i.e., 14% to 31%, 10% to 35%), in comparison with control group( 60%, 62%). CONCLUSION: It can be concluded from these experiments that even a brief exposure of cumulus enclosed oocytes to a low concentration of fentanyl, midazolam is deleterious to subsequent cleavage.
