PURPOSE: The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS: The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10degrees of mesial angulation to the center analog. Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Eventually, 40 experimental casts were produced. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. The analysis of variance was performed using the SPSS (v 12.0) program (alpha = .05), and the statistical significance was set at P < .05. RESULTS: The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. However, no significant difference was observed with respect to the length of the impression coping. Additionally, no significant difference was observed between the parallel and mesial angulated groups. CONCLUSION: Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. Additionally, the accuracy of the implant cast was not different for the parallel and 10degrees mesial angulated groups.

The nfa1 gene was cloned from a cDNA library of pathogenic Naegleria fowleri by immunoscreening; it consisted of 360 bp and produced a 13.1 kDa recombinant protein (rNfa1) that showed the pseudopodia-specific localization by immunocytochemistry in the previous study. Based on the idea that the pseudopodia-specific Nfa1 protein mentioned above seems to be involved in the pathogenicity of N. fowleri, we observed the effect of an anti-Nfa1 antibody on the proliferation of N. fowleri trophozoites and the cytotoxicity of N. fowleri trophozoites on the target cells. The proliferation of N. fowleri trophozoites was inhibited after being treated with an anti-Nfa1 polyclonal antibody in a dose-dependent manner for 48 hrs. By a light microscope, CHO cells co-cultured with N. fowleri trophozoites (group I) for 48 hrs showed severe morphological destruction. On the contrary, CHO cells co-cultured with N. fowleri trophozoites and anti-Nfa1 polyclonal antibody (1: 100 dilution) (group II) showed less destruction. In the LDH release assay results, group I showed 50.6% cytotoxicity, and group II showed 39.3%. Consequently, addition of an anti-Nfa1 polyclonal antibody produced a decreasing effect of in vitro cytotoxicity of N. fowleri in a dosedependent manner.

PURPOSE: Laparoscopy is being widely utilized beyond the field of surgery. We report on the early experience of laparoscopic CAPD catheter placement in adult ESRD patients. In addition, we investigate the question of whether laparoscopic CAPD catheter insertion can be used as a feasible long-term procedure. METHODS: Laparoscopic CAPD catheter placement was performed in 28 patients by one surgeon, between June, 2010 and October, 2013, and observed. A retrospective outcome study was conducted based on review of medical records. RESULTS: A total of 28 laparoscopic procedures were performed. The mean age of patients who underwent laparoscopic placement of a catheter was 60.3 years old. The most common cause of ESRD was uncontrolled hypertension combined with diabetes. The procedure took 45.7 minutes. Peritoneal dialysis was introduced on postoperative day eight, after one week of daily washing and no dialysate leaks were observed. Two incidences of catheter-related complications were observed: one incidence of catheter obstruction (due to its m igration and omental w rapping, w hich was m anaged with surgical removal) and one incidence of peritonitis (which was controlled with antibiotics). CONCLUSION: Laparoscopic CAPD catheter placement using tw o ports is a simple procedure with minimal complication. Laparoscopic CAPD catheter placement will gain greater acceptance as an alternative to the traditional method of CAPD catheter placement.

Over the past three decades, radionuclide myocardial perfusion scintigraphy (MPS) has become established as the main functional cardiac imaging technique for ischemic heart disease. It is currently appropriate for all aspects of detecting and managing ischemic heart disease, including diagnosis, risk assessment and stratification, assessment of myocardial viability, and evaluation of left ventricular function. The purpose of this article was to review recent trends in nuclear cardiology practice, excluding positron emission tomography. The past few years have brought several rapid developments that have increased photon sensitivity in nuclear cardiology scanner hardware. Additionally, software applying new methods of single photon emission tomography (SPECT) reconstruction on conventional and dedicated systems has preserved or even improved SPECT image quality with lower count statistics. On the other hand, much interest has been shown in lowering the radiation dose by the stakeholders of MPS.

Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.

The most frequent cause of continuous ambulatory peritoneal dialysis (CAPD) drainage failure is catheter migration. We experienced a rare case of CAPD drainage failure due to fracture of Tenckhoff catheter. A 56-year-old man presented for evaluation of CAPD drainage failure. KUB showed broken radio opaque line of the Tenckhoff catheter proximal to the internal cuff. It was thought that CAPD drainage failure was due to catheter fracture. CAPD drainage failure had been treated successfully with surgical catheter reinsertion. Our case demonstrated that catheter fracture should be considered in the differential of CAPD drainage failure.

In our previous study, we observed that hydrosalpingeal fluid (HSF) adversely effect mouswe embryo development and hatching. The aim of this study was to evaluate the effect of HSF as assessed by the blastocyst development rate (BDR) and by cell counting in vitro HSF was collected from nine patients undergoing salpingoneostomy to correct hydrosalpinx. Two-cell embryos were obtained from superovulated ICR mice. T6 medium and T6+/-0.4% bovine serum albumin were used as control media. T6 medium containing 10% or 50% HSF and 100% HSF from each patient were used as test media. Nine to 15 embryos were cultured in microdrops prepared from each of these media. To assess the total cell number within each blastocyst, the blastocysts were fixed and stained with Hoechst 33342 to facilitate cell counting. The mean BDR in two control media were 88.89% and 85.40%. The mean BDR in media containing 10%, 50%, 100% HSF were 85.87%, 89.58% and 75.57%, respectively (*: p<0.05). The overall mean cell count (+/-SEM) in control media were 87.6+/-9.65 and 90.12+/-11.38. The BDR was affected adversely only by 100% HSF and not in media containing 10% or 50% HSF. Mean cell counts were decreased significantly only in blastocysts cultured 100% HSF (63.8+/-13.66; p<0.01) but not in blastocysts cultured in 10% or 50% HSF (91.3+/-12.44 and 82.9+/-18.27, respectively). Thus, it is concluded that HSF has no embyotoxic effect but has a mildly negatively effect on embryonic growth and development.

Much attention has been paid to the insertion of central venous catheter(CVC) but their removal is a subject discussed rarely. After removal of a central venous catheter, rare but potentially life-threatening, transient cardiopulmonary collapse or neurological dysfunction had developed. The failure to appreciate these complications may be a significant factor in their high mortality. Early recognition and treatment may be made possible by a high index of suspicion. In this report, the clinical courses of two patients with central venous catheter removal distress syndrome are reviewed. Also guidelines for safe removal of CVC are formulated. An awareness of potential CVC removal complications is most important for their prevention and timely treatment. CVCs should be removed with the same degree of meticulous attention to detail that accompanies their insertion. Medical personnel should be reminded that removal of the catheter is an integral component of CVC management.

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. METHODS: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. RESULTS: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). CONCLUSION: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.
