We report a case of 17-year-old female with juvenile onset systemic lupus erythematosus Who developed symptomatic unilateral sacroiliitis. She had neither HLA-DR3 nir B27 antigens. Though sacroiliitis have been reported in mail SLE patient. it has been rarely reported in female patients. The rare coexistence of SLE and sacroiliitis. described in this case. may not be determined soley by genetic factors; sacroiliitis may be just an infrequent manifestation of SLE.

The occurrence of fistulous tract between the thoracic subarachnoid space and the pleural cavity due to injury is uncommon. The one was developed after traffic accident and treated by surgical repair of the fistula : The other was post-operative complication of costotransversectomy for T2 sympathectomy. The complication was realized by the surgeon who was aware of the small leakage of cerebrospinal fluid from the dura propria of the T2 nerve root at the time of surgery. Intermittent pleural punctures for drainage and semisitting position were followed by spontaneous closure of the fistula. These cases were reported so that the uncommon condition might be added to the differential diagnosis of pleural effusion.

The bilateral vanishing testes syndrome is a rare condition in which the vanishing testes were once present but atrophied due to compromise in blood supply. We present a case of bilateral vanishing testes syndrome which was confirmed with laparoscopy and exploratory laparotomy following hormonal therapy The diagnosis of vanishing testes syndrome can be established by following criteria without surgical exploration. These criteria include a normal male phenotype with XY karyotype, absence of Mullerian structures on rectal examination or ultrasonography, elevated gonadotropins(FSH alone or FSH and LH), and no significant increase in serum testosterone after hCG stimulation. However, patients who do not fit these criteria should have laparoscopy or exploration to look for occult gonadal tissue and spermatic vessels.

DNA double-strand breaks (DSBs) occur commonly in the all living and in cycling cells. They constitute one of the most severe form of DNA damage, because they affect both strand of DNA. DSBs result in cell death or a genetic alterations including deletion, loss of heterozygosity, translocation, and chromosome loss. DSBs arise from endogenous sources like metabolic products and reactive oxygen, and also exogenous factors like ionizing radiation. Defective DNA DSBs can lead to toxicity and large scale sequence rearrangement that can cause cancer and promote premature aging. There are two major pathways for their repair: homologous recombination(HR) and non-homologous end-joining(NHEJ). The HR pathway is a known "error-free" repair mechanism, in which a homologous sister chromatid serves as a template. NHEJ, on the other hand, is a "error-prone" pathway, in which the two termini of the broken DNA molecule are used to form compatible ends that are directly ligated. This review aims to provide a fundamental understanding of how HR and NHEJ pathways operate, cause genome instability, and what kind of genes during the pathways are associated with head and neck cancer.

PURPOSE: Simple prostatectomy has been a mainstay of therapy for patients with large prostatic adenoma. We describe laparoscopic approach for resection of large prostatic adenoma as an alternative to open simple prostatectomy. MATERIALS AND METHODSaterials and Methods: From July 2006 to May 2007 we performed Laparoscopic simple prostatectomy on 10 patients who were diagnosed with clinically benign prostate hyperplasia(maximal urine flow rate(MFR) < or=10ml/sec, International Prostate Symptom Score(IPSS) > or=12 scores, and prostate weight > or=75g). The steps of our extraperitoneal 5 port technique were longitudinal cystotomy, subcapsular plane development, enucleation of the obstructing prostatic adenoma, insertion of Spongospan into the prostatic fossa, traction of 22Fr balloon catheter and suture repair of cystotomy. RESULTS: We successfully performed the operation in all cases without conversion. The mean patient age is 68.1 years old(60-73). The mean preoperative PSA, prostate volume were 8.8ng/ml(1.8-16.9), 97g(74.1- 120.6). The mean operating time and estimated blood loss were 204min (160-275) and 720ml(300-1,200). The resected mass weight was 45.5g (23-70). There were no major complications. The mean hospitalization stay and drain remove days were 11.3 days(9-14) and 5.6 days(4-8). The mean preoperative MFR, IPSS/quality of life(QoL) and were 2.8ml/sec(0-9.6), 25/5(14-35/4-6) and 270ml(250-310). At 3 months postoperatively, the mean MFR, IPSS/QoL and residual urine volume were 15.6ml/sec(12-23), 10/2.6(5-12/2-4) and 16.75(10-40). CONCLUSIONS: Laparoscopic simple prostatectomy could be a useful method for the treatment of large benign prostate hyperplasia. However, more experiences and comparative studies are needed to document the safe and effect compared to open prostatectomy and transurethral resection of prostate.

Journal of Korean Neuropsychiatric Association 1999;38(3):583-592
OBJECTIVES: This research was performed to identify family violence by male adolescencts, and to examine the characteristics of male adolescent delinquents in terms of domestic viloence. METHODS: We surveyed 677 male adolescents including 238 delinquents from BBS(Big brothers and sisters) in Pusan, 209 criminal adolescents from adolescent correctional institution in Pusan, 230 high school students through questionnaire, MMPI(Minnesota Multiphasic Personality Inventory), and PBI(Parental Bonding Instrument), and then compared these three groups by Chi-square test, T-test, and Anova. RESULTS: In most cases, male delinquent adolescents were placed in poorer socio-economic conditions than those of students, but in better socio-economic conditions than those of criminal adolescents. In general, the assaulters were senior family members, physically stronger than sufferers, and have bad brotherliness. Compared with normal students, the serious problem of violence including violence to the ancestors in delinquent and criminal adolescents. On results of MMPI and PBI test, there were significant difference between violent group and non-violent group on the Sc score and Passive aggressive index in adolescent delinquents and parental overprotection in normal students. CONCLUSION: Generally the characteristics of family violence by male delinquent adolescents were intermediate between those of criminal adolescent and students, these results were same as those of previous socio-psychiatric study, and so the intervention in criminal adolescents is needed for the pre-vention of family violence.
