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.

PURPOSE: To assess the usefulness of 0.5 %-methylcellulose as oral contrast agent in spiral CT examinationsfor the evaluation of anastomotic site and remnant stomach in patients who have undergone subtotal gastrectomy dueto stomach cancer. MATERIALS AND METHODS: Twenty-seven patients who underwent subtotal gastrectomy for stomachcancer and were referred for the evaluation of anastomosis recurrence and lymph node metastasis wereprosepectively analyzed by spiral CT. They were divided into two groups: before scanning, group A patients drank0.5 %-methylcellulous 500ml as oral contrast agent, while those in group B drank diluted gastrografin 500ml. Threepatients were examined twice. Anatomic delineation of the anastomosis site was graded by two radiologists asexcellent (3), good (2), fair (1), or poor (0). To evaluate the degree of distension, maximal transverse andanterior-posterior diameter of remnant stomach and anastomotic sites were measured. RESULTS: In Group A, anatomicdelineation of the anastomotic site was very much better than in group B (mean score: 2.93 vs 1.80, p<0.05). Inaddition, the maximum diameters of remnant stomach and anastomotic site were significantly larger in group A thanin group B (transverse A-P remnant stomach and anastomosis site: 87.5 +/-14.7mm, 103.3 +/-20.1mm, 17.6 +/-2.9mm vs57.6 +/-20.1mm, 69.9 +/-3 5 . 0 m m , 10.7 +/-7 . 2 m m ) CONCLUSION: In patients who had undergone subtotalgastrectomy, the use of 0.5 %-methylcellulose as oral contrast agent for spiral CT showed excellent anatomicdelineation of the anastomotic site and distension of remnant stomach.

PURPOSE: This study was undertaken to determine whether lipid peroxidation induced by hydroxyl radicals play a critical role in cisplatin(cis-diamminedichloroplatinum II)-induced acute renal failure. METHODS: Animals received cisplatin at a single i.p. dose of 5 mg/kg, and changes in renal function were measured at 48 hr after cisplatin injection. RESULTS: Cisplatin caused an increase in serum creatinine level, which was accompanied by reduction in GFR. The fractional excretion of Na(+), glucose, and inorganic phosphate was increased in animals treated with cisplatin alone. Cisplatin treatment in vivo inhibited PAH uptake by renal cortical slices and Na(+)-K(+)-ATPase activity in microsomal fraction. Lipid peroxidation was increased in cisplatin-treated kidneys. When animals received the antioxidant N,N'-diphenyl-p-phenylenediamine(DPPD), the iron chelator deferoxamine, and hydroxyl radical scavengers dimethylthiourea and sodium benzoate before cisplatin injection, alterations in renal function and lipid peroxidation induced by cisplatin were significantly prevented. Exposure of renal cortical slices to cisplatin in vitro caused an increase in LDH release and lipid peroxidation, which were completely prevented by DPPD and deferoxamine. By contrast, hydroxyl radical scavengers(dimethylthiourea and thiourea) did not prevent cisplatin-induced LDH release despite they inhibited cisplatin-induced lipid peroxidation. CONCLUSION: These results suggest that the lipid peroxidation resulting from generation of hydroxyl radicals may play a role in cisplatin-induced acute renal failure. In addition, the protective effects of hydroxyl radical scavengers in vivo studies are different from the results obtained from in vitro studies using renal cortical slices.
