Malignant Neuroleptic Syndrome following Deep Brain Stimulation Surgery of Globus Pallidus Pars Internus in Cerebral Palsy / 대한중환자의학회지

Neuroleptic malignant syndrome (NMS) is a rare but potentially lethal outcome caused by sudden discontinuation or dose reduction of dopaminergic agents. We report an extremely rare case of NMS after deep brain stimulation (DBS) surgery in a cerebral palsy (CP) patient without the withdrawal of dopaminergic agents. A 19-year-old girl with CP was admitted for DBS due to medically refractory dystonia and rigidity. Dopaminergic agents were not stopped preoperatively. DBS was performed uneventfully under monitored anesthesia. Dopaminergic medication was continued during the postoperative period. She manifested spasticity and muscle rigidity, and was high fever resistant to anti-pyretic drugs at 2 h postoperative. At postoperative 20 h, she suffered cardiac arrest and expired, despite vigorous cardiopulmonary resuscitation. NMS should be considered for hyperthermia and severe spasticity in CP patients after DBS surgery, irrespective of continued dopaminergic medication.

Protective dental splint for oroendotracheal intubation: experience of 202 cases

BACKGROUND: Dental injury as a result of oroendotracheal intubation during general anesthesia is very common. We report our experiences of using mouthguard to prevent dental injury during intubation based on our protocol. METHODS: This retrospective study enrolled patients referred for preanesthetic evaluation, those patients with a history of any of the dental treatments to their anterior teeth listed on our fabrication protocol from January 1, 2009 to June 30, 2010. RESULTS: No cases of dental trauma during oroendotracheal intubation were reported among the 202 patients who used a protective device. 66% of the patients had risk factors for hard tissue damage aged 10-40 years. At the ages of 40-70 years, the incidence of risk group for periodontal damage was higher. CONCLUSIONS: Preanesthetic consultation was effective for preventing dental injury, so preanesthetic questionnaire and proper dental consultation would be helpful.

An esthetic appliance for the management of crown-root fracture: a case report

Orthodontic extrusion is usually performed by means of a fixed orthodontic appliance that utilizes arch wire attached to adjacent teeth and transfers the desired force by elastic from the wire to the root. However, clinicians often encounter cases where the bonding required for tooth traction is not possible because the adjacent teeth have been restored with ceramic or veneer. The purpose of this case report is to describe a modified orthodontic extrusion appliance that is useful when conventional orthodontic treatment is not possible. The modified appliance was fabricated using an artificial tooth, clear plastic sheeting, and a braided fiber-reinforced composite strip that covered adjacent teeth without bonding. It satisfied the esthetic and functional needs of the patient and established the optimal biologic width.

Factors Associated with Hypertension Control and Antihypertensive Medication among Hypertensive Patients in a Community / 예방의학회지

OBJECTIVES: The main objectives of this study are to identify the factors associated with hypertension control and to determine the influencing factors associated with antihypertensive therapy. METHODS: The study was conducted on 107 subjects who participated in the 1999 and 2002 Gwacheon Study and who had had uncontrolled hypertension (systolic > or=140 or diastolic > or= 90mmHg) in 1999. We compared the characteristics of the controlled and uncontrolled hypertensive group and investigated the characteristics of those taking antihypertensive medication. Univariate associations between hypertension control and its characteristics and the association between antihypertension treatment and its characteristics were tested with x2-test. We also performed logistic regression analysis. RESULTS: The participants who had their blood pressure checked within 6 months before their first measurement and those who had taken the antihypertensive medication showed significantly better hypertension control during the follow-up. The multivariate analysis showed that baseline antihypertensive therapy was the most important determinant factor of hypertension control during the follow-up. Socioeconomic level and life style did not affect hypertension control when controlled by the treatment variable in this study. The factors associated with antihypertensive therapy at follow-up were previous antihypertensive therapy, old age, and high educational level. CONCLUSIONS: Those who received antihypertensive therapy and those who had their blood pressure re-checked within 6 months both showed well controlled hypertension. The subjects with high educational level complied well with the antihypertensive regimen, but those in their forties did not.

Analysis of Sufficient Conditions in Approving Cere b rovascular and Cardiovascular Disease as Occupational Disease / 대한산업의학회지

OBJECTIVES: This study was performed to analyze the factors that affect the decision to approve workers compensation claims for cerebrovascular and cardiovascular diseases and to analyze the worker characteristics. METHODS: Three hundred, sixty-nine cases were collected based on the workers compensation records of three Seoul and Incheon Regional centers of the Labor Welfare Corporation between 1998 and 1999. They contained the general characteristics, injury information and past medical histories. The x2-test and logistic regression were performed to investigate the factors affecting the approvals. Seventy-two survivors were surveyed by telephone for job stress. Job stress was surveyed in three parts: job demands, decision latitude and personal free time. RESULTS: Of the cases, 167 obtained approval from the Corporation; the others did not. Regardless of approval, 62% of all subjects had more than one of the cerebral and cardiovascular risk factors. Especially, 53.9% of subjects had hypertension. According to the logistic regression, the fatal cases had a higher approval rate (OR=26.4, CI=9.13-76.22). The cases with working condition change (OR=6.5, CI=3.45-12.07), accidents on worksite (OR=4.9, CI=2.39-10.07), female (OR=4.0, CI=1.21-13.3), accidents at night duty (OR=2.9, CI=.156-5.39), cases occurring on duty (OR=.25, CI=1.34-4.72) and cases without past disease history (OR=1.8, CI=1.02-3.36) also had higher approval rates. Telephone survey found that the approval rate increased with decreasing freedom of personal time schedule. However, the logistic regression revealed that job stress didnt affect the approvals. CONCLUSION: To prevent cerebrovascular and cardiovascular diseases, the most important aspect is to control hypertension which is the most common risk factor among the victims. Moreover, job stress and over working should be considered in the just approval of the workers compensation claims.

A Case-Control Study on Dietary Quality and Risk for Coronary Heart Disease in Korean Men

OBJECTIVE: The purpose of this study was to investigate the association between dietary quality and the risk of coronary heart disease (CBD) among Korean men by a case-control study. METHODS: The cases were 108 male patients with a first acute myocardial infarction or a new diagnosis of angina pectoris who were admitted to a university teaching hospital in Seoul. Controls were 142 age-matched patients admitted to the departments of ophthalmology and orthopedic surgery at the same hospital. Dietary information was assessed by a nutritionist using a semiquantitative food frequency questionnaire (FFQ), and dietary quality index (DQI) scores were calculated. RESULTS: The intakes of total fat and cholesterol and body mass index (BMI) in cases were significantly higher than those in controls. The mean DQI scores were 8.6 for the cases and 9.4 for the controls. A higher DQI, which was indicative of a better quality diet, was inversely associated with the risk of CHD when comparing the highest to lowest quatiles, but borderline significant (odd ratios 0.60, 95% confidence interval 0.25-1.39, P for trend=0.05). CONCLUSIONS: Our findings suggest that better dietary quality may reduce the risk of CHD among Korean men.

Expression of Heat Shock Protein 70 by Heat Stimulation in Rabbit Chondrocytes and Articular Cartilages

OBJECTIVE: Heat therapy is one of physical therapies used most commonly in chronic osteoarthritis. The therapeutic effects of heat therapy might be attributed to induce heat shock proteins in heat-stimulated cells and tissues and therefore, to inhibit cellular damages due to inflammation. In order to investigate preliminarily the therapeutic effects of heat therapy, Hsp(heat shock protein) 70 expressions by heat stimulation were measured in cultured chondrocytes and knee joint cartilages of rabbits. METHOD: Five rabbits were used in total in this study. Three rabbits were used for chodrocytes culture and two rabbits were in vivo study. Chondrocytes were cultured from knee cartilages of three rabbits and treated at 33degreesC, 37degreesC, and 42degreesC for 20 min. In order to clarify whether heat therapy using ultrasonification can induce Hsp 70 expression in cartilage tissues, right knees of rabbits were heat-stimulated by ultrasonification for 20 min and their left knees were untreated. After 2 hours, cultured chondrocytes and cartilages were prepared and Hsp 70 expression was also observed by Western blot analysis. RESULTS: Hsp 70 expression was increased 1.48 folds in 42degreesC treated cells compared to in 37degreesC treated cells. The heat-stimulated cartilages showed 1.65 fold increases in Hsp 70 expression compared to the unstimulated cartilages. CONCLUSION: Hsp 70 expressions were increased by heat stimulation in cultured chondrocytes as well as in cartilage issues.

Timing of Menarche and Physical Growth during Childhood and Adolescence: The Kangwha Study / 예방의학회지

OBJECTIVES: To assess height, weight and body mass index from childhood to adolescence according to the age at menarche and hence to study the influence of childhood growth on the menarche age. METHODS: "The Kangwha Study" was a community-based prospective cohort study which included the entire population of 219 female first graders in Kangwha county in 1986. Among the 219 girls, 119 girls who had received complete follow up checks during the study period(1986~1997), were included in this study, except one for whom menarche age information was unavailable. The remaining 118 girls were divided into three groups according to the timing of menarche : early( or =75 percentile) maturers. RESULTS: The average age at menarche was 12.7 years : early 11.3 years, intermediate 12.6 years and late 13.7 years. The early maturers were taller and heavier between 6~8 years. But, the mean weight and body mass index at the menarche age did not differ statistically among the three groups. The weight and body mass index of the early maturers were consistently higher than those of the late maturers over the entire period of the study. CONCLUSIONS: Critical body weight and body mass index must be attained for menstruation to be attained and the age at menarche is largely determined by the childhood growth. In addition, it seems that childhood growth and age at menarche are associated with adolescent weight and body mass index.

Twelve-year tracking of blood pressure in Korean school children: the Kangwha Study

Longitudinal data from different populations have shown different degrees of tracking of blood pressure (BP). To examine BP tracking in Korean school children, 219 of 430 children (100 males, 119 females) who were 6 years old in 1986 in Kangwha County, Korea have been examined annually up to 1997 in the Kangwha Study. BP was measured twice with standard mercury sphygmomanometers and the average of the two measurements was used for the level of BP. Diastolic BP were measured at the fourth Korotkoff sound. Tracking was examined using a time-lag correlation analysis and McMahan's tracking index tau, which indicates the proportion of variation attributable to tracking apart from the natural growth component. As well the jackknife method was used to obtain the confidence interval of tau. Correlation coefficients between systolic BP from age 6 to 17 ranged from 0.39-0.54 for males and 0.44-0.57 for females. Taus for systolic BP were 0.875 (95% CI: 0.803-0.947) and 0.900 (95% CI: 0.809-0.991) in males and females, respectively. Correlation coefficients between diastolic BP from age 6 to 17 ranged from 0.28-0.47 for males and 0.14-0.47 for females. Taus for diastolic BP were 0.983 (95% CI: 0.897-1.000) and 0.800 (95% CI: 0.717-0.883) in males and females, respectively. These findings showed strong evidence for BP tracking in Korean school children from childhood to late adolescence.

Diabetic Muscle Infarction: A case report

Diabetic muscle infarction (DMI) is an unusual neuromuscular complication of diabetes mellitus. It tends to occur in young, poorly controlled, insulin dependent diabetic patient with end-organ complication. We report a 24-year-old woman with diabetic muscle infarction in both lower extremities. DMI began with an abrupt onset of pain, tenderness, swelling and formation of a firm mass. MRI revealed an increase in the signal intensity on T2 weighted image and SPECT showed an increased uptake of Tc-99m-pyrophosphate (PYP) in affected muscles. We report this case with review of the literature.

Twelve-year Incidence of Hypertension and Its Risk Factors in a Lean Population: the Kangwha Study / 예방의학회지

OBJECTIVES: The purpose of this study was to examine the twelve-year incidence of hypertension, and to find risk factors for the incidence in adult population in Kangwha County, Korea. METHODS: In 1986, 413 males(mean age 37 years) and 434 females(mean age 33 years) were examined in the Kangwha Study. Among 764 non-hypertensive participants, 164 males and 214 females were reexamined in 1998. Blood pressure(BP) was measured with standard mercury sphygmomanometers. Multiple logistic regression analysis was used to estimate the relative risk of risk factors on the incidence of hypertension. RESULTS: During the 12-year period, 68 of 164 males and 53 of 214 females developed hypertension. In a multiple logistic model adjusted for age and pulse rate, baseline BP, baseline body mass index(BMI) and BMI change during the follow-up period were significantly related to the incidence of hypertension. Adjusted relative risk(RR)s of baseline high-normal BP were 3.90(95% CI: 1.81-7.84) in males, and 12.72(95% CI: 3.70-30.73) in females. Compared with lower baseline BMI group, adjusted RRs of middle baseline BMI group were 2.66(95% CI: 1.19-5.70) in males, and 2.33(95% CI: 0.95-5.55) in females. Adjusted RRs of upper baseline BMI group were 3.52(95% CI: 1.53-7.67)in males and 3.63(95% CI: 1.50-8.43) in females. Increase of BMI was positively related to the incidence in males(adjusted RR=2.71, 95% CI: 1.00-6.71) and females(adjusted RR=3.05, 95% CI: 1.29-6.88). CONCLUSIONS: The twelve-year incidence of hypertension was 41.5% in males, and 25.8% in females. Baseline BP, baseline BMI, and BMI change were strongly related to the incidence of hypertension.

The Prevalence of Cancer in Kangwha County / 예방의학회지

OBJECTIVES: Most descriptive studies of cancer have focused either on cancer incidence or mortality. Cancer prevalence has rarely been estimated. Cancer prevalence data can be used as a measure of the economic and social burden of cancer and are also useful for health care planning. This study attempts to estimate cancer prevalence in Kangwha county. METHODS: This investigation is based on data of Kangwha cancer registry. The data include all cases of cancer diagnosed from 1983 through 1992. We define "prevalent cases" as cancer patients who is alive as of January 1, 1993. For each five-year age group, the number of "known prevalent cases" is added to the number of "estimated prevalent cases". Prevalence is calculated by dividing these sums by the populations of Kangwha County on December 31, 1992(derived from Kangwha Statistics Annual). RESULTS: Crude prevalence of cancer among males and females are 536.7 and 601.1 per 100,000 respectively. Gastric cancer is the most common malignant neoplasm(213.2 per 100,000, crude prevalence) among males. It is followed by lung cancer(45.1 per 100,000), liver cancer(32.8 per 100,000), rectal cancer(25.4 per 100,000) and colon cancer(25.4 per 100,000). Cervical cancer is the most common cancer(201.9 per 100,000, crude prevalence) and is followed by gastric cancer(91.5 per 100,000), thyroid cancer(64.8 per 100,000), breast cancer(57.2 per 100,000) and rectal cancer(32.7 per 100,000) among females. CONCLUSIONS: We tried to estimate cancer prevalence based on the Kangwha cancer registry for the first time in Korea. The estimation of cancer prevalence based on a population-based cancer registry will be more correct and useful as the data accumulate. We will make another estimation in the near future.

A Case-Control Study on Risk Factors of CHD: Vegetable consumption and risk for CHD in Korean men / 한국역학회지

The purpose of this study was to investigate the association of vegetable consumption with the incidence of CHD in Korean men by a case-control study. The case group consisted of 108 patients with EKG-confirmed myocardial infarct or angiographically-confirmed(>or=50% stenosis) angina pectoris admitted to a university teaching hospital in Seoul, Korea. Controls were 142 age-matched patients admitted to the departments of ophthalmology and orthopedic surgery at the same hospital. Dietary intake was assessed by a nutritionist using a semiquantitative food frequency method, while body mass index (BMI), tobacco use, and past history of cardiovascular disease were determined during an interview and examination. The consumption of vegetables was classified by the average frequency of intake(less than 3 times/week, 3~4 times/week, 5~6 times/week, more than once/day). The percentage of subjects who consumed vegetables less than 3 times per week was 29.6% for cases and 17.6% for controls; while men who consumed vegetavle more than once per day were 16.7% for cases and 32.4% for controls. After the adjustment for age, body mass index, and tobacco use, the odds ratio of men who consumed vegetables at least once per day was 0.38(95% confidence interval, 0.18-0.85) compared with men who consumed vegetables less than three times per week. These results suggested that in a population with a relatively low fat intake, consumption of vegetables at least once per day may reduce the risk of CHD in men.

The Effects of Topical Anesthetic Ointment to the Pain during Electromyographic Examination

OBJECTIVES: To investigate the effects of topical anesthetic ointment (lidocaine 2.5% prilocaine 2.5%) to the pain during electromyographic examination. METHOD: Thirty-two adults without known neurological disorders were studied. The needle Electromyography (EMG) of flexor carpi radialis (FCR) muscle and the motor and sensory conduction studies of median nerve were performed after the application of topical anesthetic ointment in one upper extremity and compared to the other side upper extremity without anesthesia. The intensity of pain was assessed with the Visual Analog Scale (VAS) and the characteristics of pain was evaluated with the modified short-form McGill pain questionnaire. RESULTS: The VAS score of the needle EMG of FCR muscle in the anesthetized side was significantly lower to that of the non-anesthetized side (P<0.01). And the characteristics of pain were shooting (10 cases, 31.3%), or throbbing (6 cases, 18.8%) in the anesthetized side and dull (13 cases, 40.6%), or numb (7 cases, 21.9%) in the non-anesthetized side. The VAS scores of the sensory and motor nerve conduction study of median nerve were not significantly different in both sides. CONCLUSION: The application of topical anesthetic ointment decreases the intensity and changes the characteristics of pain during the needle EMG.

The effect of sodium and potassium intake on blood pressure change in Korean adolescents / 예방의학회지

In order to investigate the effect of the urinary excretion of sodium and potassium on the change on blood pressure over 3 years, 668 adolescents aged 13 years living in Kangwha area were investigated in a longitudinal follow-up study. Two measurements were taken on each blood pressure (diastolic, systolic) and the average of the two readings was used in the analysis. Sodium and potassium intake were estimated by the determination of those electrolytes in 24hr urine. The mixed model regression analysis was used to identify the effect of urinary sodium and potassium on the change of blood pressure after controlling for BMI of each age. On simple bivariate analysis no relationship was found between urinary sodium excretion and systolic or diastolic blood pressure among both male and female, however, a significant positive association between urinary potassium excretion and systolic blood pressure among male. The results of mixed regression analysis showed that the body mass index (BMI) were more influential that urinary electrolytes among this study subjects. It suggested that risk factors observed from the adults, may not be identical with that of the growing aged population. After control of the BMI and age, significant association between sodium and diastolic BP among male, and association between potassium and systolic BP among female, were found. In summary, the results indicate that growth has been more influential than dietary factor on blood pressure for growing aged population.

Four-year change and tracking of serum lipids in Korean adolescents / 예방의학회지

It has been known that there is a tracking phenomenon in the level of serum lipids. However, no study has been performed to examine the change and tracking of serum lipids in Korean adolescents. The purpose of this study is to examine the changes of serum lipids in Korean adolescents from 12 to 16 years of age, and to examine whether or not there is a tracking phenomenon in serum lipids level during the period. In 1992 serum lipids(total cholesterol(TC), triglyceride(TG), LDL cholesterol(LDL-C), HDL cholesterol(HDL-C)) were measured in 318 males, 365 females who were 12 years of age in Kangwha county, Korea. These participants have been followed up to 1996 and serum lipids level were examined in 1994 and 1996. Among the participants 162 males and 147 females completed all three examinations in fasting state. To examine the effect of eliminating adolescents with incomplete data, we compared serum lipids, blood pressure and anthropometric measures at baseline between adolescents with complete follow-up and adolescents who were withdrawn. To examine the change of serum lipids we compared mean values of serum lipids according to age in males and females. Repeated analysis of variance was used to test the change according to age. We used three methods to examine the existence of tracking. First, we analyzed the trends in serum lipids over 4-year period within quartile groups formed on the basis of the first-year serum lipids level to see whether or not the relative ranking of the mean serum lipids among the quartile groups remained in the same group for 4-year period. Second, we quantified the degree of tracking by calculating Spearman's rank correlation coefficient between every tests. Third, the persistence extreme quartile method was used. This method divides the population into quartile groups according to the initial level of blood lipids and then calculates the percent of the subjects who stayed in the same group at follow-up measurement. The decreases in levels were noted during 4 years for TC, LDL-C, primarily for boys. The level of HDL-C decreased between baseline and first follow-up for both sexes and girls. Tracking, as measured by both correlation coefficients and persistence extreme quartiles, was evident for all of the lipids. The correlation coefficients of TC between baseline and 4 years later in boys and girls were 0.55 and 0.68, respectively. And the corresponding values for HDL-C were 0.58 and 0.69. More than 50% of adolescents who belonged to the highest quartile group in TC, HDL-C and LDL-C at the baseline were remained at the same group at the examination performed 2 years later for both sexes. The probability of remaining at the same group was more than 35% when examined 4 years later. The tracking phenomenon of TG was less evident compared with the other lipids. Percents of girls who stayed at the same group 2 years later and 4 years later were 42.9% and 25.7%, respectively. It was evident that serum lipid levels tracked in Korean adolescents. Researches with longer follow-up would be needed in he future to investigate the long-term change of lipids from adolescents to adults.

Changes in blood pressure and determinants of blood pressure level and change in Korean adolescents / 예방의학회지

Many studies have led to the notion that essential hypertension in adults is the result of a process that starts early in life: investigation of blood pressure(BP) in children and adolescents can therefore contribute to knowledge of the etiology of the condition. a A unique longitudinal study on BP in Korea, known as Kangwha Children's Blood Pressure(KCBP) Study was initiated in 1986 to investigate changes in BP in children. This study is a part of the KCBP study. The purposes of this study are to show changes in BP and to determine factors affecting to BP level and change in Korean adolescents during age period 12 to 16 years. A total of 710 students(335 males, 375 females) who were in the first grade at junior high school(12 years old) in 1992 in Kangwha County, Korea have been followed to measure BP and related factors(anthropometric, serologic and dietary factors) annually up to 1996. A total of 562 students(242 males, 320 females) completed all five annual examinations. The main results are as follows: 1. For males, mean systolic diastolic BP at age 12 and 16 years old were 108.7 mmHg & 118.1 mmHg(systolic), and 69.5 mmHg & 73.4 mmHg(diastolic), respectively. BP level was the highest when students were at 15 years old. For females, mean systolic and diastolic BP at age 12 and 16 years were 114.4 mmHg & 113.5 mmHg(systolic) and 75.2 mmHg & 72.1 mmHg(diastolic), respectively. BP level reached the highest point when they were 13-14 years old. 2. Anthropometric variables(height, weight and body mass index etc) increased consitantly during the study period for males. However, the rate of increase was decreased for females after age 15 years. Serum total cholesterol decreased and triglyceride increased according to age for males, but they did not show any significant trend for females. Total fat intake increased at age 16 years compared with that at age 14 years. Composition of carbohydrate, protein and fat among total energy intake was 65:15:20 at age 14 and 16 years. 3. Most of anthropometric measures, especially, height, body mass index(BMI) and triceps skinfold thickness, showed a significant correlation with BP level in both sexes. When BMI was adjusted, serum total cholesterol showed a significant negative correlation with systolic BP at age 12 years in males, but at age 14 years the direction of correlation changed to positive. In females serum total cholesterol was negatively correlated with diastolic BP at age 15 and 16 years. Triglyceride and creatine showed positive correlation with systolic and diastolic BP in males, but they did not show any correlation in females. There was no consistent findings between nutrient intake and BP level. However, protein intake correlated positively with diastolic BP level in males. 4. Blood pressure change was positively associated with changes in BMI and serum total cholesterol in both sexes. Change in creatine was associated with BP change positively in males and negatively in females. Students whose sodium intake was high showed higher systolic and diastolic BP in males, and students whose total fat intake was high maintained lower level of BP in females. The major determinants on BP change was BMI in both sexes.

A roentgenocephalometric study on the position of the lower central incisor / 대한치과교정학회지

By observing the correlationships between the characteristics of the facial pattern and the methods of establishing the position of the lower central incisor to the five reference lines on the lateral roentacenocephalograms, the author tried to fine the most useful method of them, the criteris of which were the independence of a vatiation according to facial patterns, the close rslationships with soft tissue and lip balance, and the simple and consistent usefulness in clinical practice. The subject consisted of forty normal occlusions, forty class II div 1 malocclusion, forty class III malocclusions, ten treated class II div 1 cases and ten treated class III cases, all were in 14-17 yrs of age. The findings of this study are as follows: 1. The position of the lower central incisor to FP, OP, MP and NB showed variations according to ANB, FMA, Facial convesity and holdaway angle. 2. The position of the lover central incisor to AP line (A-Pog) was not correlated with ANB, FMA, Facial convexity and Holdaway angle, so it can be used consistently, regardlesss of the facial pattern. 3. The linear position of the incisal edge of the lower central incisor to AP line has a profound influence on harmonious soft tissue and lip balance.
