PURPOSE: To evaluate the correlation between lower urinary tract symptoms (LUTS) and premature ejaculation (PE) in Korean men older than 40 years. MATERIALS AND METHODS: In total, 258 men older than 40 years completed the International Prostate Symptom Score (IPSS; total score, storage symptoms [ST], and voiding symptoms [VD]), a 5-item version of the International Index of Erectile Function (IIEF-5), and the Premature Ejaculation Diagnostic Tool (PEDT). The study examined the relationship between LUTS and PE. In the PEDT, PE is defined as a score > or =11. RESULTS: The prevalence of PE was 29.1% with the PEDT versus a self-reported value of 49.5%. The prevalence of PE was 30.9% in 40 to 59-year-old men (21.3%) and 28.1% in 60 to 79 year-old men (78.7%). In men 40 to 59 and 60 to 79 years old, the mean PEDT, IPSS, and IIEF-5 scores were 8.65 and 7.88, 13.5 and 12.38, and 15.83 and 13.69, respectively. No significant correlations were observed between the total and subscale scores of the IPSS (p=0.204) and the PEDT (p=0.309) with increasing age, whereas a significant negative correlation was detected between the IIEF-5 and age (p=0.002). The PEDT score was significantly correlated with the IPSS-ST (r=0.326, p<0.001), IPSS-VD (r=0.183, p=0.005), IPSS-total (r=0.310, p<0.001), and IIEF-5 total (r=-0.248, p<0.001). CONCLUSIONS: LUTS, especially storage symptoms, were related to PE. In elderly men, control of both erectile dysfunction and LUTS may play an important role in managing PE.

Problems related to agitation in the ICU patients include cardiorespiratory instability, ina bility to cooperate with nursing care, failure to maintain op timal positioning in bed, dis- ruption of life sustaining tubes and catheters, and injuries to patients and hospital person- nel. Thus, the ability to provide safe, controllable, and reversible sedation can be important in the care of critically ill patients. Midazolam is a water soluble imidazobenzodiazepine with a rapid onset of ac tion and short elimination half life compared with diazepam or lorazepam. We evaluated the use of midazolam by continuous infusion for prolonged sedation of critically ill adult patients. The results were as follows ; 1) Midazolam infusion effectively controlled severe agitation in all patients. 2) No episodes of cardiovascular depression due to midazolam occur red during the study period. 3) In one patient, tolerance was developed 6 days after infusion. 4) Mean time to alertness was 2.23 hours. 5) In a renal failure patient, there was no significant prolongation of time to alertness. These results suggest that midazolam infusion provides safe, controllable, and reversible sedation in the care of critically ill patients.

This article reports the case of a woman who developed a pure motor paraplegia following epidural analgesia. 80mg of Depomedrol and 2ml of 1% lidocaine were injected epidurally for relief of back pain. Within one day the patient complained of severe pain in both lower extremities and the left lower extremity rapidly became paraplegic. Myelography showed no obstruction and compression. The paraplegia was permanent in the left lower extermity. We note a number of potential etiologies and analyze their possible mechanism of action.

The purpose of this study was to evaluate the difference of subgingival bacterial compositions between periodontally healthy and diseased sites. Subgingival plaque samples were obtained from 100 sites in 20 untreated adult periodontitis patients(experimental group), and 100 sites in healthy individuals(control group). Before sampling, probing pocket depth(PPD) and clinical level of attachment(CAL), Plaque Index(PI), and Sulcus Bleeding Index(SBI) were recorded for each sampled sites. Microbial samples were collected from the bases of gingival sulci or periodontal pockets with sterile curettes. The samples were examined under darkfield microscope(x400). At least 150 bacteria were evaluated and categorized on the basis of bacterial morphology and motility, i.e. cocci, non-motile rods, motile rods, and spirochetes. In control group, subgingival microbial flora consisted of 73.7% of cocci, 20.0% of non-motile rods, 4.3% of motile rods, and 2.0% of spirochetes. The microbial samples from experimental group consisted of 51.5% of cocci, 19.4% of non-motile rods, 17.6% of motile rods, and 11.6% of spirochetes. The proportion of cocci was higher in control group than in experimental group. Proportions of motile rods and spirochetes were higher in experimental group than in control group. The proportion of nonmotile rods in experimental group and control group was not significantly different. Sulcus Bleeding Index and Plaque Index showed high correlation with the bacterial composition. These findings suggests that examination of subgingival bacterial proportion may serve as more sensitive mirror of the local periodontal status than clinical parameters.

Pressure controlled ventilation has been proposed to recruit closed alveolar units and improve oxygenation through changing the inspiratory flow pattern from a square wave as used with volume controlled ventilation to a rapidly exponentially decaying curve and through maintaining airway pressure at a constant level throughout the inspiratory phase. The purpose of this study was to evaluate the cardiorespiratory efficacy of pressure controlled ventilation in severe respiratory failure. Cardiorespiratory values were measured in ten patients with severe respiratory failure on volume controlled and pressure controlled ventilation. Tidal volume, ventilatory rate, PEEP, inspiratory:expiratory ratio and FIO2 were maintained at the same level for both ventilatory modalities. Changing from volume controlled ventilation to pressure controlled ventilation was associated with significant improvement in PaO2 and decrease in peak inspiratory pressure. There were no significant changes in other cardiorespiratory values, such as arterial blood pressure, heart rate, inspiratory pause pressure and static compliance. These results suggest that pressure controlled ventilation may be a beneficial ventilatory modality in the treatment of severe respiratory failure compared to volume controlled ventilation.

The nature of the implant surface can directly influence cellular response, ultimately affecting the rate and quality of new bone tissue formation. The aim of this in vitro study was to investigate if human osteoblast-like cells, Saos-2, would respond differently when plated on disks of magnesium titanate and machined titanium. Magnesium titanate disks were prepared using Micro Arc Oxidation(MAO) methods. Control samples were machined commercially pure titanium disks. The cell adhesion, proliferation and differentiation were evaluated by measuring cell number, and alkaline phosphatase(ALPase) activity at 1 day and 6 day after plating on the titanium disks. Measurement of cell number and ALPase activity in Saos-2 cells at 1 day did not demonstrate any difference between machined titanium and magnesium titanate. When compared to machined titanium disks, the number of cells was reduced on the magnesium titanate disks at 6 day, while ALPase activity was more pronounced on the magnesium titanate. Enhanced differentiation of cells grown on magnesium titanate samples was indicated by decreased cell proliferation and increased ALPase activity.

Authors report two cases of hypothermic patients with Osborne's J wave on electrocardiogram. A 46-year-old male with liver cirrhosis was brought to the emergency room by ambulance due to comatous mental status. On exammination, the body temperature was below 35 degree C. By rewarming using warm normal saline intravenous infusion and hot pack application on the chest, his body temperature rose up to 36 degree C and regained consciousness. Later, he expired with afterdrop phenomenon. Another 41-year-old stuporous quadriplegic male with post-traumatic cerebral palsy was brought to the emergency room by his family complaining weakness and vomiting. On exammination, the body temperature was below 35degree C. He was rewarmed using warm normal saline intravenous infusion and hot pack application on the chest. However, he could not regain his normal body temperature and expired due to irreversible shock.

BACKGROUND: The organizational justice model can evaluate job stressor from decision-making process, attitude of managerial or senior staff toward their junior workers, and unfair resource distribution. Stress from organizational injustice could be harmful to workers' mental health. The purpose of this study is to explore the association between organizational justice and depressive symptoms in a securities company. METHODS: To estimate organizational justice, a translated Moorman's organizational justice evaluation questionnaire (Korean) was employed. Cronbach's α coefficient was estimated to assess the internal consistency of the translated questionnaire. To assess depressive symptoms, the Center for Epidemiologic Studies Depression (CES-D) scale was used. The link between the sub-concepts of the organizational justice model and depressive symptoms was assessed utilizing multiple logistic regression models. RESULTS: The risk of depressive symptoms was significantly higher among workers with higher levels of all subcategory of organizational injustice. In the full adjusted model odds ratio (OR) of higher level of procedural injustice 2.79 (95% confidence interval [CI], 1.58–4.90), OR of the higher level of relational injustice 4.25 (95% CI, 2.66–6.78), OR of higher level of distributional injustice 4.53 (95% CI, 2.63–7.83) respectively. Cronbach's α coefficient of the Korean version was 0.93 for procedural justice, 0.93 for relational justice, and 0.95 for distributive justice. CONCLUSIONS: A higher level of organizational injustice was linked to higher prevalence of depressive symptoms among workers in a company of financial industry.
