Induction of general anesthesia with direct laryngoscopy and tracheal intubation is routine procedure but causes varying degree of sympathetic stimulation such as increasing in blood pressure and heart rate. Many approaches have been tried to attenuate these hemodynamic responses. To evaluate the effects of nicardipine, a new calcium channel blocker, for prevent sympathetic stimulation induced by direct laryngoscopy and tracheal intubation, we administered nicardipine (40 mg P.O.) 60 minutes before laryngoscopy and endotracheal intubation. 60 patients, ASA physical status 1,2, scheduled operation, were selected randomly. We divided these patients into two groups. Group 1: control, valium 0.1-0.2 mg/kg P.O. (N=30), Group 2: valium 0.1-0.2 mg/kg with nicardipine 40 mg P.O. (N=30). We measured systolic blood pressure, diastolic blood pressure and heart rate before premedicstion, before induction and 1,3,5,10 minutes after intubation in both groups and compared with control group. The results were follows ; 1) Systolic blood pressure and diastolic pressure in nieardipine group were significantly decreased before induction after premedication. 2) After induction systolic blood pressure increased in both group (p<0.005) but increasing rate was significantly less than in nicardipine group (p<0.005). 3) After intubation diastolic pressure decreased significantly in nicardipine group (p<0.005). 4) The changes of heart rate were no difference in both groups.

Adenomyosis is a common disease of middle-aged women and adenomyoma is a variety of adenomyosis that formed localized tumor. Cystic degeneration of an adenomyoma is a rare clinical manifestation. A 30-year-old parous woman suffered from severe dysmenorrhea and menorrhagia for about 5 months, was operated under the impression of endometriosis of the pelvis. Following the operation, cystic degeneration of an adenomyoma was found incidentally. The authors experienced a case of adenomyosis that formed cystic tumor of uterus and presented with a pertinent literatures.

Monogenic diabetes, including maturity-onset diabetes of the young, neonatal diabetes, and other rare forms of diabetes, results from a single gene mutation. It has been estimated to represent around 1% to 6% of all diabetes. With the advances in genome sequencing technology, it is possible to diagnose more monogenic diabetes cases than ever before. In Korea, 11 studies have identified several monogenic diabetes cases, using Sanger sequencing and whole exome sequencing since 2001. The recent largest study, using targeted exome panel sequencing, found a molecular diagnosis rate of 21.1% for monogenic diabetes in clinically suspected patients. Mutations in glucokinase (GCK), hepatocyte nuclear factor 1α (HNF1A), and HNF4A were most commonly found. Genetic diagnosis of monogenic diabetes is important as it determines the therapeutic approach required for patients and helps to identify affected family members. However, there are still many challenges, which include a lack of simple clinical criterion for selecting patients for genetic testing, difficulties in interpreting the genetic test results, and high costs for genetic testing. In this review, we will discuss the latest updates on monogenic diabetes in Korea, and suggest an algorithm to screen patients for genetic testing. The genetic tests and non-genetic markers for accurate diagnosis of monogenic diabetes will be also reviewed.

The AO internal fixation system(the Fixateur Interne) is effective in reducing and stablizing a variety of unstable thoracolumbar fracture patterns. It is relatively effective in decompressing the canal of retropulsed bony fragments associated with burst fracture. Sixty-Two patients with unstable thoracolumbar spine fractures were treated with the AO internal fixator. They were followed for an average of 21 months(range 15-29 months). A compartive radiographic analysis of kyphosis and vertebral height was made using pre-operative, post-operative and follow-up radiogram. Changes in neural canal compromise were measured in 18 cases of burst fractures. Failure of instrumentation occured in 9 cases which were carefully analyzed. Recently, we've constructed the system of which the Schanz screws would be directed divergently in sagittal plane in the hope that the load to the screws might be reduced, thus the failure rate.

A 33-year old male was admitted due to continuous high spiking fever for 2 months via local clinic. He had been diagnosed pulmonary tuberculosis at local clinic. However, spiking fever had not been controlled by anti-tuberculous medications. Chest PA showed confluent consolidation on right upper & mid-lung field. 5 anti-tuberculous regimens (Streptomycin, Isoniazid, Rifampin, Ethambutol, Pyrazinamaide) were administered initially and steroid therapy was followed for relieving toxic symptoms Very slowly resolved chest X-ray lesion and continuous fever suggested the possibility of misdiagnosis. After 60th hospital day, the chest X-ray lesion was resolved gradually and fever subsided almost completely. He was discharged on 76th hospital day with anti-tuberculous drugs and steroid(prednisolon), without any other problems except sustained mild fever.

PURPOSE: To evaluate the lung changes in healthy smokers, as seen on inspiratory and expiratoryhigh-resolution computed tomography (HRCT). MATERIAL AND METHODS: Twenty-seven healthy smokers (light smokers,below 20 pack-years, n=16; heavy smokers, above 20 pack-years, n=11) and 25 nonsmokers underwent inspiratory andexpiratory HRCT. All healthy smokers had normal pulmonary function and chest radiography. Parenchymal andsubpleural micronodules, ground-glass attenuation, centrilobular and paraseptal emphysema, bronchial wallthickening, bronchiectasis and septal line were evalvated on inspiratory scan and by air-trapping on expiratoryscan. RESULTS: On inspiratory scan, parenchymal micronodules were observed in one of 25 nonsmokers(4%), two of 16light smokers(13%) and five of 11 heavy smokers(45%); subpleural micronodules in two(8%), four(25%), two(18%);ground-glass attenuation in 0(0%), one(6%), three(27%); centrilobular emphysema in 0(0%), one(6%), three(27%);paraseptal emphysema in three(12%), 0(0%), five(45%); bronchial wall thickening in 0(0%), two(13%), one(9%),bronchiectasis in 0(0%), one(6%) two(18%) and septal line in one(4%), four(25%), two(18%). On expiratory scan,air-trapping was detected in 0 of 15 nonsmokers(0%), two of 17 light smokers(12%), and five of 11 heavysmokers(45%). Statistically significant differences between these three groups were found in parenchymalmicronodules(P=0.006), ground-glass attenuation(P=0.008), centrilobular emphysema(P=0.018), paraseptal emphysema(P=0.005) and air-trapping(P=0.013) between these three groups. CONCLUSION: According to the findings of HRCT,heavy smokers had higher frequency of parenchymal micronodules, ground-glass attenuation, centrilobular andparaseptal emphysema, and air-trapping than nonsmokers and light smokers.

BACKGROUND: Cisatracurium, one of 10 isomers of atracurium, undergoes pH and temperature-dependent Hofmann elimination in plasma and tissues. Physiologic changes may affect the pharmacodynamics of neuromuscular bldegrees Cking agent during pregnancy. So, we compared the difference in the infusion rate and its spontaneous recovery of cisatracurium between full-term pregnant and nonpregnant women. METHODS: Muscle relaxation of full-term pregnant(group I, n=10) and nonpregnant(group II, n=10) women was maintained by continuous infusion of cisatracurium to keep 1st twitch response of train-of-four(TOF) at 5~10% of control. After discontinuation of infusion, recovery index was measured without reversals using the accelerograph. RESULTS: The infusion rate of cisatracurium in group I(1.25+/-0.16 mcg/kg/min) was not significantly different from that in group II(1.31+/-0.22) and recovery indices were not different between two groups(10.7+/-2.0 vs. 11.6+/-1.9 min). CONCLUSION: The infusion rate of cisatracurium in parturients to maintain surgical relaxation is not different from that in non-parturients. For Cesarean section, the usual infusion rate of cisatracurium is recommeneded to achieve the adequate surgical relaxation.

BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is characterized by sudden anterograde and retrograde amnesia lasting for up to 24 hours. Diffusion-weighted magnetic resonance imaging (DWI) in cases of TGA and ischemia demonstrates a high frequency of high signal intensities restricted to the hippocampus, and this has been proposed as an etiology of TGA. The aims of this study were to characterize the DWI and single-photon-emission computed tomography (SPECT) findings during the acute and recovered phases of TGA and to correlate the findings with oculomotor abnormalities. METHODS: Five consecutive patients with a clinical diagnosis of TGA underwent DWI and SPECT of the brain within 24 hours after symptom onset and again 3 days later. Eye movements were also recorded using three-dimensional video-oculography. RESULTS: In all patients, DWI disclosed small punctuate (1-3 mm), high-signal lesions in the lateral portion of the hippocampus. The initial SPECT also revealed hypoperfusion in the cerebellar vermis, which had recovered by the follow-up examination. Three patients showed saccadic hypermetria or impaired smooth pursuit only during the acute phase. CONCLUSIONS: Our patients with TGA showed cerebellar vermian hypoperfusion in addition to ischemic insults to the lateral hippocampus. The oculomotor abnormalities observed in our patients support the occurrence of cerebellar dysfunction during the TGA attack.

BACKGROUND: This study purposed to analyze the relationship between regional obesity rates and regional variables. METHODS: Data was collected from the Korean Statistical Information Service (KOSIS) and Community Health Survey in 2012. The units of analysis were administrative districts such as city, county, and district. The dependent variable was the age-sex adjusted regional obesity rates. The independent variables were selected to represent four aspects of regions: health behaviour factor, psychological factor, socio-economic factor, and physical environment factor. Along with the traditional ordinary least square (OLS) regression analysis model, this study applied geographically weighted regression (GWR) analysis to calculate the regression coefficients for each region. RESULTS: The OLS results showed that there were significant differences in regional obesity rates in high-risk drinking, walking, depression, and financial independence. The GWR results showed that the size of regression coefficients in independent variables was differed by regions. CONCLUSION: Our results can help in providing useful information for health policy makers. Regional characteristics should be considered when allocating health resources and developing health-related programs.
