Recent studies suggest the flow cytometric DNA ploidy analysis may be useful in defining the biologic behavior and prognosis in prostatic adenocarcinoma. Flow cytometric nuclear DNA ploidy analysis was used to study the relationship between DNA ploidy, clinical stage and histopathological grade in thirty two patients with prostatic adenocarcinomas diagnosed from 1987 to 1990. The incidence of aneuploidy in the total population was 18 of 32 (56.3%). The frequency of aneuploidy increased with advancing stage and 63.2% of carcinomas with distant metastases were aneuploidy. Aneuploidy was more frequent in high Gleason sum carcinomas than in low. The incidence of aneuploidy in carcinomas with high Gleason grade (Gleason sum 8 to 10) was 77.8%. comparing to 33.3% in low Gleason grade (Gleason sum 2 to 4). When carcinomas classified according to both DNA ploidy and degree of glandular differentiation, then subgroups with the highest and lowest degree of malignant potential became apparent. None of diploid tumors with low Gleason grade (Gleason sum 2 to 4) formed metastasis, but 71.4% of aneuploidy tumors with high Gleason grade (Gleason sum 8 to 10) formed metastases. The influence of DNA ploidy on survival was examined with Kaplan-Meier method and the generalized Wilcoxon test. Overall, the patients with diploid tumor had a survival advantage over patients with aneuploid tumor (p<0.05). In patients with stage C and D, there was increasing tendency of survival in diploid group. In conclusion flow cytometric determination of DNA ploidy in prostatic adenocarcinoma is correlated strongly with clinical stage and Gleason sum and can be expected to be a valuable adjunct b clinical stage and histopathological grade in the assessment of malignant potential of prostatic adenocarcinoma.

The diagnosis of a Battered Child Syndrome is made by the pediatrician, surgeon and the radiologist because almost parents deny the diagnosis or refuse to answer the doctor's questions. The imaging modalities play a key role in the investigation and documentation of the battered child syndrome, because of the high frequency of the typical skeletal lesion. Although physical abuse is denied by parents, the recognition of this entity is possible by the primary diagnostic imaging study in the suspected child abuse. The imaging studies are either a bone scan and x-ray series or a complete radiolographic skeletal survey by X-ray series. In an expected intracranial injury, a CT scan of the head is mandatory We experienced a case of Battered Child Syndrome in a 6 month-old male infant who had subdural hemorrhage and fractures of skull and ribs in different stages of healing and repair. The brief review of the literature was made.

BACKGROUND: We investigated the risk factors for the recurrence of anterior shoulder instability after arthroscopic surgery with suture anchors and the clinical outcomes after reoperation. METHODS: A total of 281 patients (February 2001 to December 2012) were enrolled into our study, and postoperative subluxation and dislocation were considered as recurrence of the condition. We analyzed radiologic results and functional outcome including the American Shoulder and Elbow Surgeons Evaluation Form, the Korean Shoulder Society Score, and the Rowe scores. RESULTS: Of the 281 patients, instability recurred in 51 patients (18.1%). Sixteen out of 51 patients (31.4%) received a reoperation. In terms of the functional outcome, we found that the intact group, comprising patients without recurrence, had a significantly better functional outcome than those in the recurrent group. The size of glenoid defect at the time of initial surgery significantly differed between intact and recurrent group (p<0.05). We found that the number of dislocations, the time from the initial presentation of symptoms to surgery, and the number of anchor points significantly differed between initial operation and revision group (p<0.05). The functional outcome after revision surgery was comparable to intact group after initial operation. CONCLUSIONS: Eighteen percent of recurrence occurred after arthroscopic instability surgery, and 5.6% received reoperation surgery. Risk factors for recurrence was the initial size of glenoid defect. In cases of revision surgery, good clinical outcomes could be achieved using additional suture anchor.

The cryopreservation of Red Blood Cells has many advantages of which the most important one is that it can be stored for a long period. However, in Korea, Research regarding frozen blood is still in its early stage. We evaluated the effects of transfusion of the frozen-thawed RBCs in dogs. The whole bloods were collected from 5 dogs, and the packed RBCs were obtained by centrifugation method. We made the frozen RBCs by using 40% glycerol method and stored it in -80 degrees C refrigerate for 1 month. The frozen RBCs were thawed in the 37 degrees C water bath and washed by Cell washer according to the standard protocol, and evaluated the status of them being compared with that of the unfrozen. The majorirty of the results were satisfactory to the allowable limit except high plasma hemoglobin and potassium. The frozen-thawed bloods were transfused to the two dogs and carefully observed the effects and its complications. The results were that the average value of the hemoglobin was elevated about 0.6g/dL more after transfusion than before, and there were no significant complication related to the transfusion. Thus, The frozen thawed blood transfusions in case of the experiment with dogs were proved to be safe and as effective as fresh blood, and The above method appeared to be feasible to human blood.

BACKGROUND: Metabolic syndrome is a major risk factor for cardiovascular disease. The combination of an aging population with a chronic diseased population is leading to an increase in the mortality rate due to cardiovascular diseases. The purpose of this study was to assess the prevalence of metabolic syndrome in the Korean population and to evaluate its related factors for sex differences. METHODS: From April 2007 to December 2008, a total of 2,729 volunteers aged 40-69 years living in Changwon city underwent a clinical examination at a hospital in Changwon, Korea. Metabolic syndrome was diagnosed following the criteria defined in Circulation 2009. The clinical examination included measuring anthropometric variables and cardiovascular risk factors, while lifestyle factors were assessed through a questionnaire. RESULTS: The prevalence of metabolic syndrome in our sampling pool was 25.2% with a break down by sex showing a rate of 30.2% in men and 22.2% in women. Related factors associated with metabolic syndrome common to both sex were age, self-health assessment, and alcohol consumption. Sleep duration seemed to be a related factor in men, while income, education, and menstruation status played significant roles in women. CONCLUSIONS: To better manage metabolic syndrome, men need to be educated on alcohol use and women of low socioeconomic status require particular attention as do the aging population and postmenopausal women.

Objectives:
This study analyzed the decline in quality of life according to age in the chronic disease patient group, quantified it as a quantitative index, and compared it by sex and chronic disease.
Methods:
In the 2017-2019 Korea National Health and Nutrition Examination Survey database, 11,473 adults aged 19 years or older, excluding cancer patients, were analyzed for age-specific changes in the EQ-5D Index by chronic disease. The decline in quality of life according to age in patients with chronic diseases was analyzed by linear regression analysis while controlling for general characteristics. Then, linear regression analysis was performed according to sex.
Results:
In the case of the control group, the quality of life decreased by 0.0004 for every 1-year increase in age(P<0.001). By chronic disease, asthma(β=0.0019, P<0.001), arthritis(β=0.0017, P=0.002), thyroid disease(β=0.0016, P=0.015), dyslipidemia(β=0.0011, P=0.020), and hypertension(β=0.0009, P=0.027) mostly showed a greater decrease in quality of life than the control group. In addition, when divided into two groups by sex, hypertension(β=0.0012, P=0.029), thyroid disease(β=0.0041, P=0.038), and arthritis(β=0.0022, P<0.001) showed a significant decrease in quality of life only in male. Diabetes(β=0.0056, P=0.038), dyslipidemia(β=0.0022, P=0.001) significantly decreased quality of life only in female.
Conclusions
Chronic disease had a negative impact on patients perception of quality of life, and the more severe the pain and activity limitation due to the chronic disease, the more severe it was. It also showed different patterns according to sex. Therefore, it is necessary to allocate more medical resources and provide policy support to prevent chronic diseases, which are serious social problems.

BACKGROUND: This study was performed to examine the relationship between alcohol consumption and obesity according to facial flushing in Korean males. METHODS: The 1,198 men in this study were divided into four groups according to the amount of alcohol they consumed: non-drinkers (ND), lower moderate drinkers (LM, < or =7 standard drinks per week), higher moderate drinkers (HM, 7 to 14 drinks per week), and heavy drinkers (HD, >14 drinks per week). They were also separated into two groups according to facial flushing: non-flushers and flushers. Obesity and abdominal obesity were defined as body mass index of 25 kg/m2 or higher and waist circumference of 90 cm or higher, respectively. RESULTS: In LM and HM groups without flushing, the risks of obesity and abdominal obesity were not significantly increased compared to those of non-drinkers. However, in the HD group without flushing, those risks were significantly increased [OR, 1.55; confidence interval (CI), 1.01 to 2.40, and OR 1.63; CI 1.02 to 2.58, respectively]. In the LM group with flushing, those risks were not significantly increased. However, in HM and HD groups with flushing, the risks of obesity and abdominal obesity were significantly increased (OR, 2.10; CI, 1.07 to 4.16, and OR, 2.06; CI, 1.05 to 4.06, respectively, in HM; and OR, 2.16; CI, 1.08 to 4.34, and OR, 2.50; CI, 1.26 to 4.98, respectively, in HD). CONCLUSION: This study suggests that the risk of obesity is increased in moderate flushing drinkers compared to non-drinkers and in heavy non-flushing drinkers.
