PURPOSE: The objective of this study was to evaluate the Caspase 3 and p21 expression level and to understand the correlation between Caspase 3 expression and the clinical factors in renal cell carcinoma. MATERIALS AND METHODS: Forty-two patients with renal cell carcinoma were enrolled in this study. Immunohistochemical staining of Caspase 3 and p21 was performed in formalin-fixed and paraffin-embedded tissue sections using rabbit polyclonal antibody (Caspase 3) and mouse antibody (p21). The Caspase 3 and p21 expression levels were compared with the TNM stage, Fuhrman grade, pathological type and survival rates. RESULTS: The Caspase 3 expression level correlated only with the Fuhrman grade (p=0.017). There was no significant correlation between the Caspase 3 and p21 expression level. The prognostic values did not correlate with the Caspase 3 and p21 expression level. CONCLUSIONS: The prognostic value of the Caspase 3 expression level in renal cell carcinoma was insufficient. The relationship between Caspase 3 and p21 was not proven in renal cell carcinoma, and new factors may be implicated with Caspase 3.

PURPOSE: To evaluate the usefulness of Gd-DTPA enhanced MR imaging in determining the metastatic lymph nodes in uterine cervical carcinoma. MATERIALS AND METHODS: Sixty nine patients with histologically proven cervical carcinoma underwent Gd-DTPA enhanced MR imaging. One hundred and thirty-eight pelvic regions(69 right,69 left) in 69 patients were analyzed for lymph node metastases. Pelvic lymph nodes were considered to be abnormal if they were greater than lcm in diameter and were enhanced on postcontrast T1 weighted images. RESULTS: Metastatic lymph nodes were found in 22 pelvic regions by surgicopathologic examinations. On MR imaging there were 14 true positives, 106 true negatives, 10 false positives and 8 false negatives. Gd-DTPA enhanced MR image had an accuracy of 86.9%, a sensitivity of 58.3%, a specificity of 91.4%, a positive predictive value of 58.3% and negative predictive value of 92.9% in evaluation of pelvic lymph node metastases. CONCLUSION: MR imaging with contrast enhancement may be useful in the evaluation of pelvic lymph node metastases in patients with uterine cervical carcinoma.

OBJECTIVES: Chronic alcohol consumption has been known to result in various neurocognitive deficits. Many neuropsychological studies revealed that the major disturbances occurred in the executive function learning and short-term memory. visuospatial performance function, perceptuo-motor skills and abstraction and problem solving abilities. This study was done to identify which cognitive areas might be mainly affected. METHODS: The cognitive disturbance was evaluated using the Korean Version of the Mini Mental State Examination(MMSEK) and the 7 Minute Screen(7MS) in male inpatients with alcohol dependence(N=31) as well as in age and education level matched healthy male controls(N=30) Four individual tests of the 7MS were consisted of the Benton Temporal Orientation Test the Enhanced Cued Recall, the Clock Drawing and the Category Fluency. RESULTS: 1) The average scores of four individual test of the 7MS for the alcoholics were 2.77+/-4.38 for the Benton Temporal Orientation Test. 13.90+/-2.02 for the Memory Test(the Cued Recall 6.77+/-1.94, the Uncued Recall 7.10+/-2.45), 5.84+/-1.86 for the Clock Drawing and 12.58+/-3.29 for the Category Fluency. Except the Benton Temporal Orientation Test, there were statistically significant differences between test scores of alcoholics and those of controls(p<0.01). 2) The alcoholics who had MMSE-K score<24 were 9.68%. The average(+/-S.D) score of the MMSE-K for the patient group(27.23+/-2.62) was significantly(p<0.001) lower than that of the healthy controls(29.20+/-1.24) There were no statistically significant differences between four individual test scores of the 7MS of alcoholics with the MMSE-K score<24(N=3) and those of alcoholics with the MMSE-K score > or =24(N=28) 3) Four individual test scores of the 7MS seemed to have statistically significant association with such variables as MMSE-K, duration of alcohol drinking blood magnesium concentration liver function and thyroid function. CONCLUSION: Mild deficits of cognitive areas such as orientation, memory, visuospatial abilities and verbal fluency could be found in alcohol dependence.

BACKGROUND: Trichorhinophalangeal syndrome (TRPS) patients tend to have alopecia that appears to be androgenetic, and this genetic model might give clues to the pathogenesis of hair loss or hair morphogenesis. OBJECTIVE: This study was conducted to identify additional genetic evidence of TRPS and hair morphogenesis from a TRPS patient. METHODS: From one TRPS type I patient, we extracted RNA and profiled whole transcriptome in non-balding and balding scalp areas using high-throughput RNA sequencing. RESULTS: We found a total of 26,320 genes, which comprised 14,892 known genes with new isoforms and 4,883 novel genes from the non-balding and balding areas. Among these, a total of 1,242 genes showed different expression in the two scalp areas (p<0.05 and log2 fold-change >0). Several genes related to the skin and hair, alopecia, and the TRPS1 gene were validated by qRT-PCR. Twelve of 15 genes (KRT6C, KRTAP3-1, MKI67, GPRC5D, TYRP1, DSC1, PMEL, WIF1, SOX21, TINAG, PTGDS, and TRPS1) were down-regulated (10 genes: p<0.01; SOX21 and PTGDS: p>0.05), and the three other genes (HBA2, GAL, and DES) were up-regulated (p<0.01) in the balding scalp. Many genes related to keratin and hair development were down-regulated in the balding scalp of the TRPS type I patient. In particular, the TRPS1 gene might be related to androgen metabolism and hair morphogenesis. CONCLUSION: Our result could suggest a novel perspective and evidence to support further study of TRPS and hair morphogenesis.

OBJECTIVES: 'The 7 Minute Screen' was reported so sensitive to discriminate mild dementia. The test results were not influenced by the education, age and sex. Furthermore, the examiners needed no professional training. The tests covered the cognitive areas such as memory, oritention to time, verbal fluency and visuospatial or visuoconstructional abilities. The aims of this study were to evaluate the efficiency of 'The 7 Minute Screen' to discriminate differences between illnesses, and to analyze the factors affecting the test results. METHODS: 'The 7 Minute Screen' and the Mini-Mental State Examination (MMSE) were obtained from 36 inpatients with dementia of the Alzheimer's type (N=8), vascular dementia (N=8), Major depressive disorders (N=10) and alcohol dependence (N=10). The test battery was consisted of the Benton Temporal Orientation, the Enhanced Cued Recall, the Clock Drawing and the Category Fluency. RESULTS: 1) On the Benton Temporal Orientation, the highest mean scores were obtained in vascular dementia. On the memory, the lowest mean scores were obtained in vascular dementia, especially on the Uncued Recall in the dementia of the Alzheimer's type, and on the Cued Recall in vascular dementia. On the Clock Drawing, the lowest mean scores were obtained in the dementia of the Alzheimer's type. On the Category Fluency, the lowest mean scores were obtained in the dementia of the Alzheimer's type. 2) There was no statistically significant difference between 4 illness groups on the Benton Temporal Orientation. While there were no differences between 4 illness groups on total scores of memory and the Cued Recall, on the Uncued Recall showed significant difference between alcohol dependence and other illness groups (p<0.05). On the Clock Drawing, there was no significant difference between 4 illness groups. On the Category Fluency, there was significant difference between alcohol dependence and dementia of the Alzheimer's type and vascular dementia (p<0.001), and major depressive disorders (p<0.01). 3) In the dementia of the Alzheimer's type, the test scores of the Clocking Drawing were correlated positively with the education level (gamma=0.740, p<0.05), and negatively on the sex (gamma=-0.902, p<0.005), while in major depressive disorders, there was negative correlation between the Cued Recall and the age (gamma=-0.725, p<0.05). Otherwise, there were no significant correlation between the scores of individual tests with age, sex and educational level in vascular dementia and alcohol dependence. CONCLUSIONS: 'The 7 Minute Screen' seemed to be more superior to find out mild cognitive deficit than the Mini-Mental State Examination as well as it might be useful to discriminate differences between illnesses. However, some individual test results of a kind of illnesses could be influenced by the education level, age and sex.

PURPOSE: CD44 is a multifunctional adhesion molecule in cell-to-cell and cell-to-matrix interactions. This transmembrane glycoprotein exists in either standard or variant form, with the variation originating in alternative splicing. This study was designed to evaluate the role of CD44v6, one of the CD44 isoforms, in hepatocellular carcinoma and cholangiocarcinoma. MATERIALS AND METGODS: Immunohistochemical expression of CD44v6 was studied in 7 normal livers, 14 hepatocellular carcinomas and 16 cholangiocarcinomas, that were formalin fixed and paraffin embedded. RESULTS: CD44v6 was frequently expressed in the normal hepatocytes and hepatocellular carcinomas. Expression was not noted in the normal bile duct within the portal tract. CD44v6 was positively expressed in some of the proliferating bile ducts (43%) and cholangiocarcinomas (69%). CONCLUSION: CD44v6 expression may be more important in the stepwise carcinogenesis of the bile duct than in the normal hepatocyte, but further study is needed.

Intracranial pial arteriovenous fistulas (AVFs) are uncommon, high-flow connection between an artery and a vein without an intervening nidus, vascular lesions treated using endovascular approach with a variety of embolic materials. To our knowledge, hyperperfusion syndrome as a result of embolization of pial AVFs has not been reported before. We report our experience in the treatment of high-flow pial AVF using detachable coils and hyperperfusion syndrome after coil embolization.

Pediatric abusive head trauma (AHT) is a serious, repeated child abuse that causes grave brain damage. In Korea, AHT cases have been reported rarely, especially infants. We present 4 cases of AHT in infants diagnosed in our institution during last 2 years. We collected the demographic data, ophthalmologic examination, imaging study, and outcomes. The mean age was 7.2 months, and 2 infants were girls and the others were boys. All four were admitted with no history of head trauma, and among them 2 patients presented with an episode of seizure and respiratory arrest with no history of head trauma. The initial mental status was semi-coma in 3 cases, and stupor in 1 case. There were multiple retinal hemorrhages in both eyes in 2 cases; one had multiple old fractures on the extremities and another child showed multiple skull fractures. All patients underwent emergent surgery for acute bilateral subdural hemorrhages; 3 had craniotomy and another had burr-hole drainage. Two children expired and the other 2 are in vegetative status. The AHT has recently become more frequent in Korea so that neurosurgeons must alert AHT even in infants with head trauma.
