Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

This study assesses the fertilization and blastocyst-forming rate in mice cumulus-oocyte complexes (COCs) after the exposure of human ovarian endometriotic fluid. Endometriotic fluid was obtained from a single patient by aspiration at the time of a laparoscopic cystectomy and serially diluted. COCs were obtained from 46-week-old female BDF1 mice. After exposure to ovarian endometriotic fluid for five minutes, the COCs were washed three times and the oocytes were then fertilized by mice sperm. The fertilization and blastocyst formation rate and the proportion of hatching/hatched blastocyst in the four treatment groups were not inferior to those in non-exposure group.

This retrospective study was undertaken to provide information when considering aspects of future prevention and quantifying demand fir medical services. And it comprised 835 patients with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, the Yeungnam University Hospital during the past five years from January 1991 to December 1996. The medical records of this 835 patients(1,210 fractures) were reviewed and analyzed in order to obtain the clinical pattern and understand the therapeutic tendency. The following results were obtained; 1. The greatest number of patients were sustained facial bone injuries between midnight and 3:00. The monthly incidence showed in September at the most and at the least in December. The increase of facial bone injuries of 11.3% per year was shown. 2. The mean age of patients was 30 years. The most prevalent age group was at third decade(31.9%). Males were predominated more than female(3.6 : 1). 3. The most common cause was traffic accidents(41.6%) followed by violence, fall, industrial accidents and others. 4. The most common fracture was found in the nose(35.1%) followed by mandible(22.6%), zygoma(21.1%), and maxilla(11.2%). 5. Associated injuries were as following order of frequency; ophthalmologic injury(21.0%), other facial bone fractures(18.2%), head injury(10.2%). 6. Open reduction was used for 53.9% of total cases while 40.6% of total cases required closed reduction, and 5.5% of total cases treated conservatively. The complication rate was 18.5% and complications were as following order of frequency; facial asymmetry(37.2%), diplopia and enophthalmos(19.4%), and local infection(12.8%).

This is a case report of a 71-year-old woman with hereditary hemorrhagic telangiectasia (hereditary hemorrhagic telangiectasia [HHT], Osler–Weber–Rendu syndrome) involving the liver who developed ST elevation myocardial infarction and died from aggressive coronary thrombosis. HHT is an autosomal dominant hereditary disease associated with mutations of genes that regulate the endothelial surface. It has characteristic muco-cutaneous telangiectasia and other common manifestations are epistaxis, gastrointestinal bleeding, and iron-deficiency anemia. In addition, arteriovenous malformations or vascular ectases commonly occur in the pulmonary, hepatic, and cerebral circulations. Hemorrhages and thrombosis can both develop from these vascular abnormalities in HHT. Most thrombotic events are forms of venous thrombosis, such as deep vein thrombosis, while arterial thrombosis occurs infrequently. We present a case of aggressive coronary thrombosis in HHT, as a rare complication of HHT.

Objective: This study aimed to investigate sperm motility and its changes after preparation as predictors of pregnancy in intrauterine insemination (IUI) cycles. Methods: In total, 297 IUI cycles from January 2012 to December 2017 at a single tertiary hospital were retrospectively analyzed. Patient and cycle characteristics, and sperm motility characteristics before and after processing were compared according to clinical pregnancy or live birth as outcomes. Results: The overall clinical pregnancy rate per cycle was 14.5% (43/297) and the live birth rate was 10.4% (30/289). Patient and cycle characteristics were similar between pregnant and non-pregnant groups. Sperm motility after preparation and the total motile sperm count before and after processing were comparable in terms of pregnancy outcomes. Pre-preparation sperm motility was significantly higher in groups with clinical pregnancy and live birth than in cycles not resulting in pregnancy (71.4%±10.9% vs. 67.2%±11.7%, p=0.020 and 71.6%±12.6% vs. 67.3%±11.7%, p=0.030, respectively). The change in sperm motility after processing was significantly fewer in the non-pregnant cycles, both when the comparison was conducted by subtraction (post-pre) and division (post/pre). These relationships remained significant after adjusting for the female partner’s age, anti-Müllerian hormone level, and number of pre-ovulatory follicles. According to a receiver operating characteristic curve analysis, an initial sperm motility of ≥72.5% was the optimal threshold value for predicting live birth after IUI. Conclusions Initial sperm motility, rather than the motility of processed sperm or the degree of change after preparation, predicted live birth after IUI procedures.

OBJECTIVE: The aim of this study was to compare the efficacy of swim-up and density gradient centrifugation (DGC) for reducing the amount of sperm with fragmented DNA, sex chromosome aneuploidy, and abnormal chromatin structure. METHODS: Semen samples were obtained from 18 healthy male partners who attended infertility clinics for infertility investigations and were processed with swim-up and DGC. The percentages of sperm cells with fragmented DNA measured by the sperm chromatin dispersion test, normal sex chromosomes assessed by fluorescence in situ hybridization, and abnormal chromatin structure identified by toluidine blue staining were examined. RESULTS: The percentage of sperm cells with fragmented DNA was significantly lower in the swim-up fraction (9.7%, p=0.001) than in the unprocessed fraction (27.0%), but not in the DGC fraction (27.8%, p=0.098). The percentage of sperm cells with normal X or Y chromosomes was comparable in the three fractions. The percentage of sperm cells with abnormal chromatin structure significantly decreased after DGC (from 15.7% to 10.3%, p=0.002). The swim-up method also tended to reduce the percentage of sperm cells with abnormal chromatin structure, but the difference was not significant (from 15.7% to 11.6%, p=0.316). CONCLUSION: The swim-up method is superior for enriching genetically competent sperm.

PURPOSE: To investigate the associations between sperm DNA fragmentation (SDF) and embryo formation rate in normal responder women to in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). MATERIALS AND METHODS: Fifty-three consecutive, fresh IVF/ICSI cycles performed from 2014 to 2017 were selected. All women were normal responders (4 to 14 mature oocytes were retrieved) and at least one normally fertilized oocyte with two pronuclei was obtained in all cycles. Semen was collected on the day of oocyte retrieval, and SDF levels were measured by sperm chromatin dispersion test (Halosperm assay). At day 3 after insemination, embryo quality was evaluated by morphologic criteria and categorized as A/B/C/D. Top quality embryo were defined as grade A embryos with seven cells or more. RESULTS: SDF levels showed a positive linear correlation with the male's age (r=0.307, p=0.025) and a negative linear correlation with sperm motility (r=−0.491, p<0.0001). To achieve top-quality or a grade A embryo formation rate >70%, the cut-off value SDF was <30.7% for each. Among individuals with SDF <30.7%, the median top-quality or grade A embryo formation rate was significantly higher than that among individuals with SDF ≥30.7% (38.1% vs. 20.0%, p=0.038; 50% vs. 25.0%, p=0.017). CONCLUSION: In normal responder women, high SDF level resulted in low day 3 embryo formation rates. Our results suggest a paternal effect on embryo quality in IVF/ICSI cycles.

OBJECTIVE: This study aimed to develop a nomogram that predicts ongoing pregnancy after in vitro fertilization and embryo transfer (IVF-ET) using patient age and serum hormonal markers. METHODS: A total of 284 IVF-ET cycles were retrospectively analyzed. At 14 days post-oocyte pick-up (OPU), the serum human chorionic gonadotropin (HCG) and progesterone levels were measured. The main predicted outcome was ongoing pregnancy. RESULTS: Patient age and serum of HCG and progesterone levels at 14 days post-OPU were good predictors of ongoing pregnancy. The cut-off value and area under the curve (AUC) (95% confidence interval) were 36.5 years and 0.666 (0.599–0.733), respectively, for patient age; 67.8 mIU/mL and 0.969 (0.951–0.987), respectively, for serum HCG level; and 29.8 ng/mL and 0.883 (0.840–0.925), respectively, for serum progesterone level. When the prediction model was constructed using these three parameters, the addition of serum progesterone level to the prediction model did not increase its overall predictability. Furthermore, a high linear co-relationship was found between serum HCG and progesterone levels. Therefore, we developed a new nomogram using patient age and HCG serum level only. The AUC of the newly developed nomogram for predicting ongoing pregnancy after IVF-ET cycles using patient age and serum HCG level was as high as 0.975. CONCLUSION: We showed that ongoing pregnancy may be predicted using only patient age and HCG serum level. Our nomogram could help clinicians and patients predict ongoing pregnancy after IVF-ET if the serum JCG level was ≥5 IU/L at 14 days post-OPU.
