Circumcision has been popularly performed with mechanical device such as Gomco clamp, Plastibell device and other modified device. We experienced a case of denudation of entire penile epithelium and abnormal curvature during erection after circumcision using self-circumcision device (GM sense) at home. So we report with a brief review of literature.

PURPOSE: The purpose of this study is to compare treatment response and survival according to treatment modalities, such as allogeneic bone marrow transplantation (BMT), combined immunosuppression and supportive care, and according to etiologies in children with severe aplastic anemia. METHODS: Thirty-four patients who had severe aplastic anemia received either BMT, combined immunosuppression, or androgen treatment at Chonnam University Hospital from Jan. 1990 to Mar. 1998. The clinical characteristics and response according to treatment modalities or etiologies were studied retrospectively. RESULTS: 1) Patients in Group 1 received combined immunosuppression of ALG/ATG+methylprednisolone+/-cyclosporin (N=18); Group 2, BMT (N=11); Group 3, supportive treatment of oxymetholone+prednisolone+transfusion (N=5). Clinical characteristics were not different among three groups. 2) In Group 1, the response rate was 50% with complete response (CR) in 4 (22.2%) and partial response (PR) in 5 (27.8%). CR was attained in 91% (10/11) of Group 2 patients, while all 5 in Group 3 were died. Relapse was found in 1 out of 9 (11.1%) in Group 1. Three of 10 in Group 2 who had initial response experienced late graft failure. The Kaplan-Meier 4-year-survival in each group was 75.5%, 81.8% and 20%, respectively (P = 0.019). 3) Among 5 patients were Fanconi's anemia, two survived who underwent HLA- matched sibling transplants. Three patients with secondary aplastic anemia, including posthepatitis (N=2) and post-rubella responded to either BMT or immune suppression. Idiopathic cases (N=26) showed response rate of 43.8% to immunosuppression [CR, 3/16; PR 4/16], 85.7% to BMT, and 0% to supportive care. 4) The relative risk of death was 0.26 (P = 0.052) in Group 1, and 0.15 (P = 0.03) in Group 2 in comparison with Group 3. CONCLUSION: The study showed that BMT and combined immunosuppression resulted in better response and survival than supportive care in the management of childhood severe aplastic anemia. Although BMT seemed to be better than immunosuppression, effective measure to reduce late graft failure and graft versus host disease should be pursued.

We have cloned a cDNA encoding a cysteine proteinase of the Acanthamoeba healyi OC-3A strain isolated from the brain of a granulomatous amoebic encephalitis patient. A DNA probe for an A. healyi cDNA library screening was amplified by PCR using degenerate oligonucleotide primers designed on the basis of conserved amino acids franking the active sites of cysteine and asparagine residues that are conserved in the eukaryotic cysteine proteinases. Cysteine proteinase gene of A. healyi (AhCP1) was composed of 330 amino acids with signal sequence, a proposed pro-domain and a predicted active site made up of the catalytic residues, Cys(25), His(159), and Asn(175). Deduced amino acid sequence analysis indicated that AhCP1 belongs to ERFNIN subfamily of C1 peptidases. By Northern blot analysis, no direct correlation was observed between AhCP1 mRNA expression and virulence of Acanthamoeba, but the gene was expressed at higher level in amoebae isolated from soil than those from clinical samples. These findings raise the possibility that Ahcp1 protein may play a role in protein metabolism and digestion of phagocytosed bacteria or host tissue debris rather than in invasion of amoebae into host tissue.

The purpose of this study was to provide basic biometric data on Korean adults through magnetic resonance imaging (MRI)-based measurements of the distances between the apex of sacral hiatus (SH) and the termination of dural sac (DS), and between SH and conus medullaris (CM) because they are critical to the performance of epidural neuroplasty. A total of 200 patients (88 males and 112 females) with back pain, who had no spine fracture, significant spinal deformity, and spondyloisthesis were selected for this study. The subjects were of mean age 54.3 (20~84) years and mean height 161.3 cm (135~187). T2-weighted MRI images were used for correlation analysis to evaluate the relationships between the distances, and variables such as sex and height. In all patients, the mean distance between SH and DS was 62.8±9.4 mm and the mean distance between SH and CM was 232.2±21.8 mm. The minimum distance and the maximum distance between SH and DS were 34.8 mm and 93.9 mm respectively, and the minimum distance and the maximum distance between SH and CM were 155.0 mm and 284.0 mm respectively. In female patients, both the distances between the SH and DS, and between SH and CM were shorter when compared to those of the male patients (p<0.05). Both the distances between SH and DS and between SH and CM showed a significant correlation with height (p<0.01). The results of this study will provide a useful biometric data on the distances between SH and DS and between SH and CM in Korean in ensuring clinical safety and in the development of more effective catheterization techniques for epidural neuroplasty in Korean.

PURPOSE: The mortality rate of neonatal sepsis has been decreased, however, the incidence has not significantly decreased because of increased invasive procedures. This study was designed to make guidelines for choosing antibiotics by analyzing the causative microorganisms and their antibiotics sensitivity test according to the onset of neonatal sepsis. METHODS: One hundred seven cases of culture proven sepsis in 89 patients admitted to the NICU of Chonnam University Hospital from Jan. 2000 to Dec. 2004, were enrolled. By reviewing the medical records, clinical data, laboratory findings, causative organisms and their antibiotics sensitivity, and mortality were analyzed. RESULTS: The incidence of neonatal sepsis was 1.7 percent and more prevalent in premature and low birth weight infants. 85.4 percent of neonatal sepsis was late onset. Almost all microorganisms(92.9 percent) were gram-positive in early onset, however, two thirds were gram-positive and one third were gram-negative and Candida in late onset. Gram-negative organisms and Candida were more prevalent in patients who had central line. Gram-positive organisms were sensitive to vancomycin, teicoplanin, and gram-negative were sensitive to imipenem, and cefotaxime. CONCLUSION: Neonatal sepsis was more prevalent in premature and low birth weight infants. More than 90 percent were gram-positive in early onset, however, one third was gram-negative and Candida in late onset. The first choice of antibiotics were a combination of third generation cephalosporin and clindamycin in early onset, and third generation cephalosporin and glycopeptide in late onset. If there is no response to antibiotics treatment, the use of antifungal agents should be considered.

PURPOSE: With the development of neonatal intensive care and the increased use of systemic antibiotics, candida sepsis has become one of the most important causes of neonatal morbidity and mortality. The purpose of this study was to investigate the prevalence rate and its associated risk factors. METHODS: We retrospectively reviewed medical records of 28 cases with candida sepsis who were admitted in the neonatal intensive care unit(NICU) of Chonnam University Hospital from July 1995 to June 2001. Twenty-nine patients without candida sepsis were enrolled for the control group to verify the risk factors. RESULTS: The overall incidence of candida sepsis was 0.61% for all NICU admissions and 3.68% for all very low birth weight infants with the gradual increase of the annual prevalance rate over time. The endotracheal intubation, percutaneous central vein catheter(PCVC), umbilical vein catheter, total parenteral nutrition, intralipid and dopamine were more applied than the control group (P<0.01 for all). The durations of mechanical ventilator care, central catheter appliance, nothing per os, and admission were also significantly longer than the control group(P<0.01 for all). Ampicillin/sulbactam, ceftazidime, amikacin, netilmicin, teicoplanin and imipenem/cilastatin were significantly more used than the control group(P<0.05). The durations of ampicillin/sulbactam, ceftazidime, netilmicin and imipenem/cilastatin administration were also proved to be significant as the risk factors(P<0.01). CONCLUSION: The average annual prevalence rate of candida sepsis in NICU for six years was 0.61% with gradual increasing tendency over time. The elimination of the above risk factors is important in decreasing neonatal morbidity and mortality associated with candida sepsis.

PURPOSE: Vancomycin-resistant enterococci (VRE) are now nosocomial pathogens in Korea. But little is known about the prevalence of stool colonization with VRE in neonates in Korea. So we studied the prevalence and risk factors of VRE colonization in the Neonatal Intensive Care Unit (NICU). METHODS: From January 2000 to December 2004, the medical records of 294 neonates (127 cases of VRE group and 167 cases of non-VRE group, according to the results of stool culture) were reviewed retrospectively. We studied the annual prevalence of VRE and risk factors of VRE colonization in neonates. RESULTS: From 2000 to 2003, the prevalence rate of VRE in NICU increased. After preventing VRE transmission, the prevalence rate of VRE has decreased. CONCLUSION: VRE colonization increased recently. Risk factors of VRE colonization were prematurity, lower birth weight, longer hospitalization and use of vancomycin or 3rd generation cephalosporin, compared with the non-VRE group. To prevent VRE transmission among newborns, aggressive infection control strategies by NICU staffs must be implemented immediately for all babies.

Although the exact pathogenetic mechanisms of the renal ischemia-reperfusion injury(I-R injury) have not been clearly elucidated yet, the reactive oxygen spe-cies(ROS) and mononuclear cell infiltration have been suggested to contribute to this renal injury process. The cytokines and growth factors produced by infiltrated leukocytes and renal parenchymal cells could accelerate the process of tissue damage by inducing cellular proliferation, fibrosis, and further recruitment of other inflammatory cells. The renin-angiotensin sys- tem(RAS) also has been suggested to be one of the most important mediators in the renal injury process of many animal models and human renal diseases. In order to evaluate the change of the levels of TNF-alpha, endothelin-l, and TGF-beta gene expression in unilateral I-R injured renal cortical tissue, competitive RT-PCR was performed for the above mRNAs in Sprague-Dawley rats(60 minutes of ischemic time by non-traumatic vessel clamp and 24 hours of reperfusion). Also the plasma renin activity(PRA) and an-giotensin II(AII) level were measured at the time of sacrifice by radioimmunoassay. On the light miscroscopic examination, I-R injured renal cortical tissue showed typical findings of acute tubular necrosis, such as mononuclear ceU infiltration, necrosis, swelling and denudation of proximal tubular cells. Compared to control sham operated group, I-R injured group tissues showed significantiy increased level of TGF-beta(p<0.05), endothelin-l(p<0.05) and TNF-alpha(p<0.05) gene expression in 24 hours after I-R renal injury. The levels of PRA and AIl were also significantly elevated compared to sham group(p< 0.05, p<0.05, respectively). In conclusion, we speculate that the early activation of RAS and elevated gene expression of TNF-alpha, endothelin and TGF-beta of renal cortieal tissue may contribute to the early pathogenetic mechanism of I-R renal injury process.
