One of the fastest growing segments of implant dentistry is the utilization of computed tomography (CT) scan data and treatment planning software in conjunction with guided surgery for implant reconstruction cases. Computer assisted planning systems and associated surgical templates have established a predictable, esthetic, functional technique for placing and restoring implants. Especially, a philosophy of restoratively driven implant placement has been generally adopted. Recently, a variety of commercial dental fields have released their scanning and fabricating protocols and methods for restorations. This process is still being investigated and developed for the most precise and predictable outcome. This case report describes a female patient who wanted dental implants in fully edentulous areas. Restoratively driven implant placements were performed with surgical guide and the patient was fully satisfied with the clinical results, and at 5-year post restorative follow-up assessment, both implant and prosthesis were proved clinical success.

OBJECTIVES: The purpose of this study was to investigate the difference in nutrient intake between normotensive workers and hypertensive workers to obtain basic data for developing a program of effective hypertension care at work. METHODS: The subjects were 338 male workers. We measured physical data by medical examination and collected lifestyle data by questionnaire survey. Dietary intakes were collected using a food frequency questionnaire. We classified the subjects into normal, prehypertension, and hypertension groups, and compared the results of age, body mass index (BMI), blood pressure (BP), lifestyles and energy nutrients and lipids intake. RESULTS: There were significant differences in both weight and BMI between the hypertension group and the other two groups (p<0.05). The smoking levels of the prehypertension group and hypertension group were significantly higher than that of the normal group (p<0.05). The three groups also showed significant differences in drinking amount (p<0.05). There were significant differences in carbohydrate and protein intakes and the ratio of carbohydrate, protein, and fat intake (p<0.05). CONCLUSION: In this study, there was a significant difference in carbohydrate intake between normotensive and hypertensive workers, and the intake of energy nutrients and fatty acids in the prehypertension group and hypertension groups was unbalanced. Therefore, early diagnosis of workers with hypertension and prehypertension is necessary to improve lifestyles particularly food habit.

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month follow-up. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

A 70-year-old female who was diagnosed as myxoid chondrosarcoma by fine needle aspiration of a pleural mass is described. She presented with left chest discomfort of 4 months' duration and aggravating dyspnea and chest pain for 2 months. Chest X-ray and CT scan revealed a large lobulated low density mass invading chest wall at the left pleural cavity and massive pleural fluid. Fine needle aspiration was done under the impression of mesothelioma or metastatic cancer. The aspirates from the mass were very cellular and composed of isolated or clustered forms of large plump cells. Abundant cytoplasm was bluish opaque and the margin was rounded in the isolated cells, whereas clustered cells show ill-defined cell borders and aggregating tendency. The nuclei were eccentric, round to ovoid, and had fine chromatin pattern and multiple small nucleoli. Cellular pleomorphism or mitotic figure was not definite. These findings were consistent with cytologic features of chondrosarcoma. Final diagnosis was confirmed as myxoid chondrosarcoma by mediastinoscopic biopsy and the tumor showed strong positivity for S-100 protein.

Granular cell tumor is mostly benign and thought to be of Schwann cell origin. The head and neck, particularly tongue, breast, and upper respiratory tract are frequently involved. Recently, we have experienced a case of granular cell tumor of the right thigh in a 30-year old male, diagnosed by fine needle aspiration cytology which revealed distinct cytologic features. The smear revealed cellular aspirates with clear background. The tumor cells showed uniform small nuclei and abundant eosinophilic, granular cytoplasm with hazy cell border. Mitoses were not found.

PURPOSE: This study was designed to aid the diagnosis and to predict the outcorne by understanding the clinical course of nutcracker syndrome in childhood. METHODS: The clinical, laboratory, radiological and cystoscopic data from the medical records of eleven children who were diagnosed as nutcracker syndrome by gross hematuria and pressure gradient criteria (>3mrnHg) were studied retrospectively and analyzed. RESULTS: Sex ratio of the cases was 7:4, and the median age of onset was 12.8 (3-14.3) years. Six cases showed persistent and 5 cases manifested interrnittent, exercise induced hematuria. Left flank pain (64%), abdominal pain (18%), left varicocele (9%) were associated in some of the children, but hematuria was the only symptom in 36Yo. Left renal vein entrapment was documented in 10 cases by ultrasonography. Out of the 5 cases studied by renal Doppler ultrasonography, 4 and 5 cases showed higher (>5) mean left renal vein diameter ratio (Distal/ Aortomesenteric portion) and mean peak velocity ratio respectively. Unilateral bleeding from left ureteral orifice was documented in 7 of the 9 cases at cystoscopy. The mean pressure gradient between proximal left renal vein and inferior vena cava was 4.4+/-1.6 (3-7) mmHg. Hematuria of 25% and 57% of the cases disappeared spontaneously in 3 and 5 years after onset respectively. Proteinuria disappear- ed in 3 of the 5 initial proteinuric cases. CONCLUSION: Nutcracker syndrome must be considered in the differential diagnosis of non-glomerular, especially gross hematuria in childhood, and Doppler ultrasonography can aid diagnosis non-invasively. The renal function remained stable, but 4396 of the cases continued to show hematuria still 5 years after onset.

BACKGROUND: As one of harm reduction strategies, tobacco manufacturers have begun to introduce lower-yield cigarettes. Lower-yield cigarettes, so called light cigarettes, have been perceived as less hazardous by some smokers. However, there have been very few studies concerning smoking lower yield products the lead to lower nicotine absorption. We evaluated the association between brand nicotine yield of cigarettes and actual nicotine intake by measuring urinary cotinine. METHODS: Four hundred sixty four male smokers aged 18 or over who participated in health check-ups in a hospital from May to October 2007 filled out a self-administered smoking questionnaire. Urinary cotinine concentration was measured at the time of participation. The subjects were divided into three groups (ultralight [nicotine: 0.05 mg], light [0.1 mg], and regular [> 0.1 mg] group) according to the level of brand nicotine yield of cigarettes which they smoked. RESULTS: The median urinary cotinine concentrations of ultralight (N = 62), light (N = 216), and regular (N = 186) groups were 735.5 ng/mL (interquartile range, 320 to 1,300 ng/mL), 956.0 ng/mL (429 to 1,491 ng/mL), and 1,067.5 ng/mL (615 to 1,613 ng/mL), respectively. There was a signifi cant difference in urinary cotinine between the regular and the other groups (P = 0.015). However, multiple logistic regression analysis to evaluate the risk of being in the highest quartile of urinary cotinine concentration (> or = 1,532 ng/mL) after adjusting for possible confounding variables showed that the odds ratios were 0.84 (95% CI, 0.52 to 1.37) in the light nicotine group and 0.82 (95% CI, 0.38 to1.72) in the ultralight nicotine group compared to the regular nicotine group. CONCLUSION: There was no significant difference in the risk of elevated urinary cotinine concentrations in male adult smokers according to brand nicotine yield of cigarettes groups.

BACKGROUND: Morning blood pressure surge affects to cardiovascular disease risk. Short time to first cigarette (TTFC) after waking can enhance morning blood pressure surge, and accelerate atherosclerosis METHODS: We investigated that the relationship between TTFC and blood pressure. The study subjects included male current smokers (n=211) who had health check-up in Hallym University Sacred Heart Hospital from July to September, 2014. We categorized the subjects into 2 groups according to TTFC; early TTFC (TTFC <30 minutes) and late TTFC (TTFC > or =30 minutes), and the subjects who were taking antihypertensive medications or had a high blood pressure (>140 mm Hg or 90 mm Hg) were defined as hypertensive group. Multivariate logistic regression was performed to estimate the odds ratio and 95% confidence interval to investigate the association between TTFC and hypertensive group. RESULTS: Compared with late TTFC, early TTFC had higher odds (odds ratio [OR], 3.87; 95% confidence interval [CI], 1.89-7.94) for hypertensive group. After adjusting confounding factors, early TTFC was significantly associated with an increased risk of hypertension (OR, 4.43; 95% CI, 1.84-10.70). CONCLUSION: early TTFC after waking is associated with hypertension. It suggests delaying TTFC might help to control of blood pressure among the current smokers who are not ready to immediately quit smoking.

Lung function test can be influenced by technical as well as biological variables, and the quality control of test has been stressed as an important part of lung function test program. This study was done to survey the current status of lung function test program in workers' health examination, and examine the variablity of test results when quality control is not achieved. Forty nine Workers' Health Examination Institutes and 7 Pneumoconiosis Referal Centers were surveyed for their current lung function tests, types of spirometers, and performance of technicians. To examine the effect of quality control program of lung function tests on the variablity of test results, 118 miners were tested under a quality control guideline and the results were compared to those obtained ignoring 4 major areas of the guideline-spirometer calibration, minimum number of tests per session, suitable prediction equations, and selection process of final results for each tested subjects. Among surveyed Institutes and Centers, only 38%(20/53) are performing any calibration of spirometers, and most of those calibrations are done automatically by the machine. All the surveyed Institutes and Centers obtain acceptable test no more than 2 times. The background of technicians include office workers and nurse aids without an adequate training in pulmonary physiology, and the testing posture and formats vary among Institutes and Centers. When the types of pulmonary dysfunction under the definition of the Ministry of Labor were compared between those obtained with and without quality control guidelines, spirometer calibration affected the test results in 6(5.1%) out of 118 subjects. The change in the minimum number of adequate tests from 1 to 3 and more brought changes in 19(16.1%) subjects. The test results of 9(7.6%) subjects differed between two different prediction equations, and the results of 7(5.9%) subjects differed between two different selection process of final results. The current practice of lung function tests of workers needs quality control programs, and the results of this study indicate that the first remedy should be to bring the minimum number of acceptable test to more than 3.

The purpose of this study was to investigate the effect of nutrition counseling on improving metabolic syndrome (MS) risk factors. Sixty-eight subjects were grouped according to their numbers of MS risk factors. Subjects who have three or more risk factors of MS were defined as "High risk", subjects who have two risk factors of MS were defined as "low risk", and subjects who have below two risk factors of MS were defined as "no risk" group. All groups finished nutrition counseling every three weeks for 12 weeks. Anthropometric, dietary assessments (24 hr-recall) and blood samples were measured at 0 and 12 weeks nutrition counseling. After 12 weeks of intervention, anthropometric data (weight, BMI, body fat (%), and waist/hip ratio) were significantly decreased (p < 0.05) in all groups. Daily consumption of calorie was decreased significantly (p < 0.05) in the group of low risk and high risk. Blood level of fasting plasma glucose was significantly decreased (p < 0.001) in all groups after 12 weeks of intervention. Significantly, the fasting plasma glucose level was returned to normal range in the high risk group. The number of people who have three or more risk factors of MS (high risk group) was decreased from 25 to 12. Sum of MS Criteria decreased from 85 to 52 in the group of MS and decreased from 143 to 99 in all groups. These results indicate that nutrition counseling for male workers at the worksite proved to be helpful by reducing the risk factors of MS and thereby reducing the risk of cardiovascular disease. Continuing and systematic nutritional management programs should be developed and implemented for male workers at the worksites.
