PURPOSE: The aim of this study was to evaluate the process and outcome of a mobile computerized system for individual home visiting healthcare. METHODS: A nonequivalent control group non-synchronized design was employed for this study. The newly constructed system was administered to 80 healthcare providers in the experimental group for 8 weeks. Data were analyzed using descriptive analysis, t-test, and ANCOVA with the SPSS 18.0 program. RESULTS: In the process stage, the difference in the frequency of computerized information usage between the experimental and control groups was significant as 8.88+/-3.20 and 7.08+/-2.92, respectively (t=3.90, p<.001). In the outcome evaluation stage, all kinds of healthy lifestyle such as alcohol use, nutrition, weight management and mental health were not improved. CONCLUSION: The findings of this study showed that the revised mobile computerized system was an effective device for individual visiting healthcare providers. Further advanced strategies for using this system should be developed and applied in a broad range of community healthcare.

Prediction of individual outcome after cardiopulmonary resuscitation is of major medical, ethical, and socioeconomic interest but uncertain. We experienced the case thats the patient got complete neurologic recovery after the 123th day firm cardiac arrest, who had been suspected to go with poor prognosis because she got the findings of Glasgow Coma Scale 4, severe diffuse encephalopathy on encephalogram and generalized tonic-clonic seizure at the 4th day. Recently, a 29 year-old women who sustained from respiratory arrest induced presumably by sedative and anticonvulsant therapy for control of seizure that happened during local lidocaine anesthesia far mamoplasty was transfered to our emergency medical center from local private plastic office. Arrest time was about 20 minutes. On hospital arrival, she had a pulseless bradyasystole and no respiration, but spontaneous circulation was restored at 10 minutes artier CPR started. We started cerebral oriented resuscitation including mild hypothermia(34degrees C), hemodilution, calcium channel blocker infusion. On hospital day 4, patient's glasgow coma scale(GCS) was 4. On hospital clay 7, Brain Magnetic Resonance Imaging(MRI) showed high signal intensity on T2WI, involving the bilateral basal ganglia. After contrast administraton, marked enhancement can be seen at the lesion site. Patient's glasgow coma scale(GCS) increased step by step to 5 on 8th day, 7 on 14th day, 10 on 15th day, 13 on 17th day, 15 on 20th day. 40 days later the patient was discharged with minor neurologic abnormality including hand tremor, dysphonia, amenorrhea and Mini Mental State Examination(MMSE) score(26). Long-term Follow up revealed that all neurologic functional abnormality inducting hand tremor, dysphonia, amenorrhea and MMSE score(26) is completely recovered on 123th day after episode of cardiopulmonary arrest.

PURPOSE: The current study was conducted in order to identify health and nutritional status of Korean underweight women in their twenties by comparing with normal, overweight, and obese women. METHODS: Data from the 2010~2012 Korea National Health and Nutrition Examination Survey were used in this study. Subjects were 897 women aged 20~29 years. Subjects were classified according to underweight, normal weight, overweight, and obese groups based on body mass index. Health status was assessed using data from the health questionnaire and examination. Nutritional status was assessed using data from 24-hour dietary recall and a food frequency questionnaire. RESULTS: The underweight group had higher education and exercised less than the obese group. Means of blood chemistry and blood pressure of the underweight group did not differ from those of the normal weight group. Means of fasting glucose, insulin, lipid profiles, blood cell counts, and blood pressure in the underweight group were different from those of the overweight or obese group. Proportions of delivery, breast feeding, and irregular menstruation in the underweight group were lower compared with the other groups. Except retinol intake, means of nutrient intake did not differ among four groups. There were significant differences among four groups in the intakes of cereals and eggs and frequency of consumption of dairy products. CONCLUSION: The current findings showed that health and nutritional status of underweight women in their twenties did not differ from those of normal weight women. In particular, health status of underweight women in their twenties was better than that of obese women of the same ages. Further study on health and nutritional status of extremely underweight women is necessary.

PURPOSE: Serum level of the aminotransferase is the most common test in use to assess hepatocellular injury and are sensitive test of hepatocyte necrosis, but both AST and ALT level in serum rise in a variety of hepatic disorders. Some clinical study reports that AST/ALT ratio was possible to predict prognostic outcome of infants with liver disease. We have tried to assess whether AST/ALT ratio is valuable or not for predict prognosis of hepatitis and differentiate cause of it. METHODS: Serum AST, ALT, and AST/ALT ratio were evaluated in the infants with acute hepatitis. They were grouped into 12 patients with Hepatitis B surface antigen positive only(group I), 23 patients with Hepatitis B surface antibody positive only(group II), and 12 patients with not-known cause of hepatitis(group III). The 24 patients were able to follow-up of AST and ALT for 2 months. They are grouped into 12 patients with normalized AST and ALT within 2 months(group A) and 12 patients not normalized within 2 months(group B). RESULTS: 1)There were no statistical difference of mean serum level of AST and ALT that were tested on admission day, one week and 2 week of admission respectively among the group I, II, and III. 2)The value of AST/ALT ratio were increased from 0.6 on admission day to 0.9 after 2 week of admission in group I(p<0.05), decreased from 1.1 to 0.8 in group II. It were not changed in group III. 3)The mean values of AST/ALT ratio were not statistically different in group A and B. 4)The mean values of serum alkaline phosphatase, total bilirubin, and prothrombin time were not statistically different among these groups, if we exclude two cases of cholestatic jaudice, one case of acute fulminant hepatitis, and one case of hepatitis C from these groups. CONCLUSIONS: On the basis of this study, we concluded that progression of hepatitis and damage of hepatic cell was different according to the cause of hepatitis. AST/ALT ratio of the acute phase hepatitis were not able to reflect the time duration of normalization of AST and ALT and it was not related to etiology of hepatitis. For predict prognosis of infant with acute hepatitis, long term follow up is needed in many more cases of infants with acute hepatitis.

Exotropia*

Toxicogenomics has recently emerged in the field of toxicology and the DNA microarray technique has become common strategy for predictive toxicology which studies molecular mechanism caused by exposure of chemical or environmental stress. Although microarray experiment offers extensive genomic information to the researchers, yet high dimensional characteristic of the data often makes it hard to extract meaningful result. Therefore we developed toxicant enrichment analysis similar to the common enrichment approach. We also developed web-based system graPT to enable considerable prediction of toxic endpoints of experimental chemical.

PURPOSE: To compare the characteristics of patients with surgically overcorrected intermittent exotropia treated with alternate patching. METHODS: The medical records of 51 patients who underwent bilateral lateral rectus muscle recession for intermittent exotropia and required alternate patching to correct postoperative overcorrection were retrospectively reviewed. Patients with postoperative esodeviation ≥18 prism diopters (PD) were started on alternate patching on postoperative day 1, whereas those with postoperative esodeviation of 10 to 17 PD were started after 2 weeks. Postoperative esodeviation <10 PD was considered as slight intentional overcorrection after exotropia surgery. Patients not responsive to alternate patching treatment were defined as those with postoperative esodeviation ≥10 PD after 3 months of treatment. Sex, family history, age, refractive error, amblyopia, stereopsis, suppression, type of exotropia, surgical method, preoperative and postoperative angle of deviation, and start time of alternate patching were compared. RESULTS: Among 51 patients, 29 patients responded to alternate patching and 22 patients did not respond. Female sex (p = 0.04), larger preoperative exodeviation at distance (p = 0.04), late onset of postoperative maximal esodeviation (p < 0.01), larger postoperative maximal esodeviation at near (p = 0.02), and late initiation of alternate patching (p = 0.01) were associated with patients in the non-responsive group. Although postoperative angle of deviation was similar for 2 weeks, the angle of postoperative esodeviation was significantly larger in the non-responsive group than in the responsive group, beginning at 1 month postoperatively. CONCLUSIONS: Female sex, large preoperative exodeviation, late initiation of alternate patching, and large esodeviation 1-month postoperative predisposed patients to be resistant to alternate patching for postoperative overcorrection.

PURPOSE: The effect of accelerated aging on color stability of various dual-cured self-adhesive resin cements were evaluated in this study. MATERIALS AND METHODS: Color stability was examined using three different brands of dual-cured self-adhesive resin cements: G-CEM LinkAce (GC America), MaxCem Elite (Kerr), and PermaCem 2.0 (DMG) with the equivalent color shade. Each resin cement was filled with Teflon mold which has 6 mm diameter and 2 mm thickness. Each specimen was light cured for 20 seconds using light emitting diode (LED) light curing unit. In order to evaluate the effect of accelerated aging on color stability, color parameters (Commission Internationale de l'Eclairage, CIE L*, a*, b*) and color differences (DeltaE*) were measured at three times: immediately, after 24 hours, and after thermocycling. The L*, a*, b* values were analyzed using Friedman test and DeltaE* values on the effect of 24 hours and accelerated aging were analyzed using t-test. These values were compared with the limit value of color difference (DeltaE*=3.7) for dental restoration. One-way ANOVA and Scheff's test (P<0.05) were performed to analyze each DeltaE* values between cements at each test period. RESULT: There was statistically signifi cant difference in comparison of color specifi cation (L*, a*, b*) values after accelerated aging except L* value of G-CEM LinkAce (P<0.05). After 24 hours, color difference (DeltaE*) values were ranged from 2.47 to 3.48 and L* values decreased and b* values increased in all types of cement and MaxCem Elite had high color stability (P<0.05). After thermocycling, color change's tendency of cement was varied and color difference (DeltaE*) values were ranged from 0.82 to 2.87 and G-CEM LinkAce had high color stability (P<0.05). CONCLUSION: Color stability of dual-cured self-adhesive resin cements after accelerated aging was evaluated and statistically significant color changes occurred within clinically acceptable range.

PURPOSE: The TNM classification for carcinoma of the colon and the rectum provides more detail than other staging systems. This study was performed to evaluate the effectiveness of AJCC staging system (5th ed., 1997) for the colorectal cancer in predicting prognosis. METHODS: We analyzed a data base of 1,233 colorectal cancer patients (M:F=673:560) who underwent surgery in Asan Medical Center during July 1989-December 1996. Survival analysis was performed between the stages and the subgroups in same stage by using Kaplan-Meier method and log rank test. Borderline subgroup comparison between the stages was performed, also. Significance was assigned to a P value of <0.05. RESULTS: Mean age of the patients was 57 (19-90) years old. Median follow-up period was 42 (6-129) months. The number of patients in each stage were 0: 15, I: 152, II: 390, III: 465, IV: 199. The 5 year overall & disease free survival rates of each stage were 100%, 100% (in stage 0), 96.4%, 93.6% (in stage I), 82.7%, 82.2% (in stage II), 59.9%, 55.3% (in stage III), and 7.3%, 24.9% (in stage IV), respectively (P=0.000). Subgroup analysis in stage I (T1N0 vs. T2N0) and II (T3N0 vs. T4N0) revealed no differences. However, in stage III, N1 (n=246) group showed better survival than N2 (n=219) group (70.3%, 65.5% vs. 49.2%, 44.6%: P=0.000). Borderline survival analysis between stage I and II (T2N0 vs. T3N0) was significantly different (96.6%, 95.7% vs 82.7%, 82.3%: P=0.006). However, between stage II and III (T4N0 vs. T1N1), appropriate analysis was impossible due to small number of cases. CONCLUSIONS: AJCC staging system for colorectal cancer was reliable and effective in predicting prognosis. However, substages are needed in stage III.

BACKGROUND: The vascularity of the peri-implant tissue is a very important parameter in establishment and maintenance of a healthy tissue after dental implant insertion. OBJECTIVE: The purpose of this study was to compare the vascularity of the peri-implant mucosa between flap and flapless implant surgeries by using a canine mandible model. STUDY DESIGN: In six mongrel dogs, bilateral, edentulated, flat alveolar ridges were created in the mandible. After 3 months of healing, two implants were placed in each side by either the flap or flapless procedures. After another healing period of 3 months, biopsies were obtained, prepared for light microscopy and exposed to morphometric measurements. RESULTS: The supracrestal connective tissue lateral to the implant was found to be more richly vascularized in the flapless group than in the flap group. CONCLUSION: These results suggest that the flapless procedure may have an effect on increasing the vascularity of the peri-implant mucosa.
