In order to assess the efficiency of Percoll gradient centrifugation(PGC) as a method of sperm selection, we have examined morphological characteristics of spermatozoa from 40 teratozoospermic patients attending the Infertility Clinic of Inchon Gil Gerneral Hospital. Patients were divided into three groups according to percentage normal morphology in the fresh sample : group A(n=5), < 5% normal morphology : group B(n=21), 5~14% normal morphology : and group C(n=14), > 14% normal morphology. Morphology slides were perpared using Diff-Quik staining techniques and evaulated by Kruger strict criteria, under oil immersion at a magnification of X 1000, specific defects, head, neck and tail were assesed individualy. The results were as follows. 1. Following PGC, sperm samples with enhanced morphology were recovered for all groups. 2. For group A, PGC did not select a sample with significantly improved morphological characteristics. 3. Usually, sperm defects affected by PGC was head and neck. No significant difference was found for tail abnormality. In conclusion, Percoll gradient centrifugation is an efficient sperm preparation technique when the semen sample exhibits teratozoospermia, especially head or neck abnormality. However, in sample with < 5% normal form or tail abnormality, There is not significant improvement following PGC.

OBJECTIVES: The aim of this study was to know differences of characteristics between presenile and senile patients who were consulted to the department of psychiatry during medical-surgical admission. METHODS: The demographic and clinical data obtained from the medical records of psychiatric consultation in the presenile inpatients with age 50 to 64 years(N=162) and those of the senile inpatients with age over 65 years(N=171) were reviewed and compared. RESULTS: 1) The most common chief complaints for psychiatric consultation in presenile patients were somatic symptoms, anxiety and sleep disturbance in order, while cognitive decline, clouded consciousness and depressed mood were most common in senile patients with statistical significance. 2) The most frequent psychiatric diagnoses after consultation in presenile patients were delirium, mood disorder and substance use disorder in order, while delirium, mood disorder and major neurocognitive disorder were most frequent in senile patients with statistical significance. 3) There were no significant difference in numbers of physical illnesses, while numbers of therapeutic drugs for them were more in senile patients. CONCLUSIONS: Our study found significant differences between presenile and senile patients on psychiatric symptoms and diagnoses in geropsychiatric consultation. Therefore, more subdivided age-specific approach seems to be needed for the geropsychiatric consultation activities.

OBJECTIVE: The aim of this study were to investigate degree of satisfaction in referring physicians' psychiatric consultation services and their attitudes and opinions toward psychiatry, and the correlation between two them. METHOD: A total of 159 survey questionnaire were distributed to physicians in a University Hospital. The questionnaires contained the level of satisfaction in referring physicians' psychiatric consultation services and their attitudes and opinions toward psychiatry. 135 surveys were returned, representing 85% return rate. Statistical method used were Cronbach's alpha coefficient for testing reliability, factor analysis for testing validity, and t-test or ANOVA with SAS. RESULTS: Internal consistency reliability was tested by Cronbach's alpha. Cronbach's alpha was 0.8594 for total 23 items. Twenty-three items and seven factors were emerged and these contributed 66.8% of the variance in the total score. Factor I in the psychiatric consultation questionnaire was positively correlated with overall merits of the field of psychiatry in the attitude questionnaire, factor II in the psychiatric consultation questionnaire was positively correlated with possible abuses and social criticisms in the attitude questionnaire, factor III in the psychiatric consultation questionnaire was positively correlated with efficacy in the attitude questionnaire, factor V in the psychiatric consultation questionnaire was positively correlated with possible abuses and social criticisms in the attitude questionnaire, factor VI in the psychiatric consultation questionnaire was positively correlated with overall merits of the field of psychiatry in the attitude questionnaire. CONCLUSIONS: Our results supported the hypothesis that referring physicians' satisfaction to the psychiatric consultation was positively correlated with psychiatrists' attitude, and that physicians with more positive attitudes and those had more knowledge on psychiatry showed greater satisfaction in psychiatric consultation service than those without.

Purpose: The purpose of this systematic review was to elucidate the optimal age for patients undergoing total knee arthroplasty (TKA), to optimize the balance between the benefits and risks by analyzing patient-reported outcome measurements (PROM), revision rate, and mortality according to age. Materials and methods: A rigorous and systematic approach was used and each of the selected studies was evaluated for methodological quality. Data were extracted according to the following: study design, patients enrolled, patient age at the time of surgery, follow-up period, PROM, revision rate, and mortality. Results: Thirty-nine articles were included in the final analysis. The results were inconsistent in the PROM analysis, but there was consensus that PROM were good in patients in their 70s . In the revision rate analysis, there was consensus that the revision rate tends to increase in TKA in younger patients, but no significant difference was observed in patients > 70 years of age. In the mortality analysis, there was consensus that the mortality was not significantly different in patients < 80 years of age, but tended to increase with age. Conclusion This systematic review shows that the PROM were good when TKA was performed in patients between 70 and 80 years of age; the best PROM could be achieved around 70 years of age, and no significant difference in the revision or mortality rates was observed between 70 and 80 years of age; however, mortality tended to increase with age. Therefore, the early 70s could be recommended as an optimal age to undergo TKA.

BACKGROUND: i-gel(TM) is a new single-use supraglottic airway device without an inflatable cuff. This study was designed to compare the usefulness of i-gel(TM) versus a classic laryngeal mask airway (cLMA) in small children. METHODS: Sixty-three children (age range : 4-72 months) were randomly assigned to an i-gel(TM) or cLMA group. We evaluated hemodynamic data, airway sealing ability, the success rate of insertion, and adverse events including an inadvertent sliding out during ventilation. RESULTS: Demographic data and hemodynamic data obtained immediately after the insertion of these devices did not differ between the two groups. The success rates for insertion on the first attempt were 77 and 84% for i-gel(TM) and cLMA, respectively (P = 0.54), and the overall success rates were 87 and 100% respectively (P = 0.14). There were no significant differences in terms of airway leak pressure. The inserted i-gel(TM) inadvertently slid out in 8 of 31 patients but only one sliding out case occurred in the cLMA group (P = 0.02). There were no differences between the groups in terms of other side effects (e.g., coughing, bleeding) associated with the use of i-gel(TM) and cLMA (P = 0.75 and 0.49, respectively). CONCLUSIONS: Oropharyngeal leak pressure and insertion success rate of i-gel(TM) are similar to those of cLMA. However, i-gel(TM) is prone to inadvertent sliding out of the mouth in small children. Therefore, it is recommended that the i-gel(TM) should be secured more tightly to avoid displacement of the device.

It has been known that right side bypass tract ablation is more difficult and has higher recurrence rate than that of left side bypass tract, and often associated with atrioventricular block in patients with septal bypass tract. Multielectrode basket catheter (MBC) allows simultaneous rapid acquisition of numerous electrical signals generated by a selected surface area or volume of myocardium. We experienced two cases of successful catheter ablation of atrioventricular reentrant tachycardia by right septal bypass tract which were mapped by MBC with greater ease.

OBJECTIVES: The antimicrobial activity of silver nanoparticles has resulted in their widespread use in many consumer products. Yet, despite their many advantages, it is also important to determine whether silver nanoparticles may represent a hazard to the environment and human health. METHODS: Thus, to evaluate the genotoxic potential of silver nanoparticles, in vivo genotoxicity testing (OECD 474, in vivo micronuclei test) was conducted after exposing male and female Sprague-Dawley rats to silver nanoparticles by inhalation for 90 days according to OECD test guideline 413 (Subchronic Inhalation Toxicity: 90 Day Study) with a good laboratory practice system. The rats were exposed to silver nanoparticles (18 nm diameter) at concentrations of 0.7 x 10(6) particles/cm3 (low dose), 1.4 x 10(6) particles/cm3 (middle dose), and 2.9 x 10(6) particles/cm3 (high dose) for 6 hr/day in an inhalation chamber for 90 days. The rats were killed 24 hr after the last administration, then the femurs were removed and the bone marrow collected and evaluated for micronucleus induction. RESULTS: There were no statistically significant differences in the micronucleated polychromatic erythrocytes or in the ratio of polychromatic erythrocytes among the total erythrocytes after silver nanoparticle exposure when compared with the control. CONCLUSION: The present results suggest that exposure to silver nanoparticles by inhalation for 90 days does not induce genetic toxicity in male and female rat bone marrow in vivo.
