Globozoospermia is a rare type of teratozoospermia. It occurs in 0.1% of all andrological patient's and used to be considered sterile. Globozoospermic patient has 100% round headed spermatozoa, but the spermiogram is normal. The spermatozoa show oval-shape head, the lack of a nuclear envelope, acrosome, and post acrosomal sheath. OBJECTIVE: To report that a couple with infertility secondary to globozoospermia received ICSI treatment. MATERIAL AND METHOD: Case report. RESULTS: In the first trial, fertilization was failed. In the second trial, 40% of oocytes were fertilized and all of these embryos were cleaved, but pregnancy did not achieved. In the third trial, sperm injected oocytes were exposed to 10 micrometer calcium ionophore for 15 min. All of the injected oocytes were fertilized and proceeded to develop. Triplet pregnancy was achieved after the transfer of six embryos in their third cycle. One embryo vanished and the remaining twins (female) were delivered at 33 weeks of gestation by Caesarean section. CONCLUSION: This result shows that assisted activation following ICSI may overcome infertility associated with globozoospermia.

BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

Cellular schwaninoma is a variant of schwannoma, which is characterized by predominance of cellular Antoni A area, presence of mitotic activity, nuclear hyperchromasia, pleomorphism, and absence of Verocay body. These pathologic features often prompted a misdiagnosis of malignancy. However, the clinical outcome has indicated the benignity of the tumor. We have experienced a case of cellular schwannoma arising from right facial nerve with right hemifacial weakness and erosion of mastoid process. Grossly, it was a 3.5 x 3 cm sized and relatively well encapsulated mass with yellowish, friable cut surface. Microscopically, cellular growth with moderate cellular pleomorphism and some mitotic activity (5/40 HPFS, up to 2/HPF) were noted. Immunostaining for S-100 protein showed diffuse strong positive reaction.

PURPOSE: The cross-protection of 7-valent pneumococcal conjugate vaccine (PCV7) against vaccine-related serotypes has been controversial. We investigated the serological properties of cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A induced in young children aged 12-23 months after booster immunization of PCV7. METHODS: IgG and IgM antibody concentrations and opsonic index (OI) against vaccine serotypes 6B and 19F and vaccine-related serotypes 6A, 6C, and 19A were measured by ELISA and opsonophagocytic killing assay (OPA) in 4 selected immunesera. The serological properties and antigenic specificity of protective antibodies were determined by IgM depletion of immunesera, OPA, and competitive OPA against serogroup 6 and 19 pneumococci. RESULTS: Compared to pre-IgM depleted immunesera, OI of IgM-depleted immunesera against 6B and 19F decreased and OI against 6A, 6C, and 19A decreased, too. In competition OPA, free 6B and 19F polysaccharide completely inhibited the immune protection against vaccine-related serotypes 6A, 6C, and 19A as well as vaccine types 6B and 19F. CONCLUSIONS: The booster immunization of PCV7 certainly induced cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A with both IgG and IgM isotypes. Furthermore, IgM antibodies are more highly contributed to opsonophagocytic activity against vaccine-related serotypes as well as most of vaccine types than do IgG antibodies. Further studies are needed for the more immunized sera in the children as well as adults.

PURPOSE: This study was to examine the effects of 3 domains of continuing education (CE) for healthcare managers. METHODS: A group of 20 healthcare managers, attending 3 levels of CE, were the subjects. The data were collected by structured questionnaires before and after each education. The data were analyzed by Friedman test, Wilcoxon Signed Ranked Test, and Bonferroni correction. RESULTS: After completing CE, there was significant improvement on the scores of knowledge, attitude, and skills. CONCLUSION: This study suggests that CE for healthcare managers is an effective strategy to promote the competency of healthcare managers, who take care of the chronically ill patients.
