Spontaneous renal ruptures are clinically unusual, and usually occur secondary to various kinds of underlying disease, such as a benign or malignant tumor, vascular disease and infection, etc. A renal cell carcinoma is the most common cause, and those caused by a transitional cell carcinoma are extremely rare. Herein is reported our experience of a case of a spontaneous rupture, with a renal pelvis transitional cell carcinoma, in a 48-year-old man.

OBJECTIVE: To investigate the difference of gene expressions between leiomyoma and normal myometrial tissue was analzed by DNA Chip. METHODS: cDNAs retro-transcribed from equal quantities of mRNA derived from leiomyoma and corresponding normal myometrial tissue were labeled with Cy5 and Cy3 fluorescein as probes. The mixed probe was hybridized with two pieces of 3,066 double dot from a human dermal papilla cell cDNA library and scanned with a laser scanner. The acquired image was analyzed by ImaGene 3.0 software. Validation of gene expression was performed by reverse transcription-Polymerase chain reaction (RT-PCR) in 5 leiomyomas and corresponding normal myometrial tissues. RESULTS: Among many differentially expressed genes, genes with expression levels more than 3 times were found by comparing leiomyoma with corresponding normal myometrial tissue. One gene with expression levels lesser than 3 times in leiomyoma tissue compared to normal myometrial tissue was also detected. Although alterations of several genes, such as osteoblast specific factor 2, PAI-1 mRNA-binding protein, hydroxyacyl-Coenzyme A dehydrogenase/3-ketoacyl-Coenzyme A thiolase/enoyl-Coenzyme A hydratase alpha subunit (HADHA), p311, DEAD/H (Asp-Glu-Ala-Asp/His) box polypeptide 1 (DDX1), Hexokinase 1, 2 were identified in a significant high fraction of uterine leiomyoma compared to normal myometrial tissue. Cyr61 gene was shown to be markedly down-regulated in leiomyoma compared with the matched uterine myometrial control. I validated differential expression of genes by RT-PCR and demonstrated overexpression of OSF-2, HADHA, p311, DDX1, Hexokinase 1, 2. CONCLUSION: DNA chip techniques are effective in screening differential gene expression between leiomyoma tissue and normal myometrial tissue. These genes may be related to the genesis and development of uterine leiomyoma. Analysis of the human leiomyoma gene expression profile by DNA chip may be helpful gene diagnosis, treatment and prevention of this disease.

OBJECTIVE: Head circumference (HC) has been reported to be an index of cognitive functioning in the elderly and in Alzheimer's patients. The object of the study is to find the relationship between HC and cognition. METHODS: A total of 7,603 subjects over 60 years of age were analyzed from preliminary data of Gwangju Dementia and Mild Cognitive Impairment Study. HC was manually measured and cognitive functioning was assessed by the Korean version of the Mini Mental State Examination (K-MMSE). RESULTS: Correlational analysis showed that HC was associated with age (r=-0.14, p<0.01), education (r=0.33, p<0.01), height (r=0.26, p<0.01), and K-MMSE (r=0.28, p<0.01). Also, even after adjusting for confounding variables (age, education, height, gender) the positive association between HC and K-MMSE score remained significant (beta=0.18, p<0.001). CONCLUSION: The results suggest that HC may play an important role in predicting cognitive impairment in the elderly.

BACKGROUND: Pulmonary artery banding (PAB)in the functional univentricular heart (UVH)is a palliative procedure for staging toward the Fontan procedure;however,it is known to be a risk factor. MATERIALS AND METHOD: The records of all 37 patients with functional UVHs who underwent surgical palliation using PAB between September 1989 and August 1999 were reviewed retrospectively.We investigated the aortic arch obstruction,the development and progression of subaortic stenosis after PAB,and risk factor of mortality according to surgical method. RESULT: In 37 neonates and infants with single ventricular physiology,aortic arch obstruction was combined in 7.There were 6 early deaths (16.2%)after PAB and 3 late deaths (8.1%)after Fontan operation.The actuarial overall survival including early mortality at 3 and 5 years were 8 0 .7+/-6.6%,72.2 +/-8.2% respectively. Among 31 patients who survived PAB,27 patients (87.1%)could become candidates for Fontan operation;22 patients(71.0%)completed Fontan operation with 3 deaths and 5 were waiting bidirectional cavopulmonary shunt(BCPS)or Fontan operation (follow-up mean 4.5 year,minimal 2 year). Subaortic stenosis developed in 8 patients after PAB (8/29,27.6%);3 cases in the patients without arch anomaly (3/22,13.6%)and 5 in those with arch anomal y (5/7,71.4%).The subaortic stenosis was managed with Damus-Kaye-Stansel procedure (DKS)in 6 patients without operative mortality and conal septum resection in 2 without long-term survivor. Analysis of risk factors established that aortic arch obstruction was strongly associated with subaortic stenosis (p<0.001).The only risk factor of late mortality was Fontan procedure without staged palliation by BCPS (p=0.001). CONCLUSION: PAB is effective as an initial palliative step in functional UVH.And the high risk group of patients with aortic obstruction can undergo effective short-term PAB as an initial palliative step,with subsequent DKS for subaortic stenosis.This strategy,initial PAB and careful surveillance,and early relief of subaortic stenosis can maintain acceptable anatomy and hemodynamics for later Fontan procedures.

BACKGROUND/AIMS: Recently, treatment using an endoscopic device is actively being developed. Techniques for incision and bleeding control have been developed, but endoscopic suturing remains to be perfected. Using an endoscopic suturing technique, a variety of diseases could be managed noninvasively. We have attempted to use a new endoscopic suturing device which enables a continuous suture using a flexible upper endoscope. METHODS: A suturing device was designed where a semicircular needle could sew through tissue by rotation making a continuous suture possible. RESULTS: We successfully sutured the stomach tissue of a dog using an optimized suturing device model. CONCLUSIONS: The initial model was found to have some problems. However, we hope to develop a continuous suturing device for flexible upper endoscope procedures in Korea.
