Even though the nonketotic hyperglycemia is a metabolic disorder, it complicates hemic- horea-hemiballism rarely. Moreover, generalized chorea-ballism associated with nonketotic hyperglycemia in diabetes mellitus is very rare, so it has not been reported in Korean literature. Although the precise pathophysiologic mechanisms of these disorders are still poorly understood, deficiency of gamma aminobutyric acid (GABA) in nonketotic hyperglycemia or reduced GABAnergic inhibition by striatal lesion may increase inhibitory output to subthalamic nucleus. These result loss of pallidal inhibition and produce contralateral hemichorea-hemiballism. The striatal lesions, such as transient ischemia with reactive astrocytosis or small amount of petechial hemorrhage, are related with changes of magnetic resonance image (MRI) findings presumably. We report a diabetic old woman who developed generalized chorea-ballismus as a very rare complication of nonketotic hyperglycemia. Her brain MRI showed high signal intensity in left lentiform nucleus and right pallidum on T1 weighted images and low signal intensity in bilateral putamen on T2 weighted images with highly enhanced corresponding lesions on T1 weighted enhancement images.

Primary cutaneous aspergillosis is rare. In this report we describe primary skin infection by Aspergillus in 9 children with leukemia. The skin lesion was characterized clinically by erythematous macule and papule associated with pain and itching, followed by a rapid progression to ulcer and central black eschars with raised erythematous border at the site of venipuncture, insertion of intravenous cannula, or where arm boards had been taped to extremities. Diagnosis was confirmed by skin biopsy and wound culture. Positive revealed in 6 patients, including A. glaucus in 2 cases, A. flavus in 1 case. Treatment consisted of temporary withdrawl of anticancer chemotherapy, intravenous amphotericin B, oral flucytosine, itraconazole and/or rifampin. One patient recovered completely without antifungal medication with resolution of leukopenia. Six of eight treated patients recovered. One patient discharged against medical advice, while cutaneous aspergillosis was improving. One patient died with persistent skin lesion and neutropenia. We conclude that primary cutaneous aspergillosis is increasingly recognized in association with intravenous cannula, intravenous puncture or prolonged contact with arm boards in immunocompromised patients, and that this serious disease can be treated successfully with appropriate management.

PURPOSE: The purpose of this study was to compare the marginal fitness and fracture load of the zirconia copings according to the design with different thickness and coloration. MATERIAL AND METHODS: The evaluation was based on 80 zirconia copings. Zirconia copings were fabricated in design with different thicknesses using CAD/CAM system (Everset, KAVO dental GmbH, Biberach, Germany). The designs of copings were divided into four groups. The first group consisted of copings with uniform thickness of 0.3 mm. The thickness in the second group was 0.3 mm on the buccal surface and 0.6 mm on the lingual surface. The third group consisted of coping with uniform thickness of 0.6 mm. The thickness in the fourth group was 0.6 mm on the buccal surface and 1mm on the lingual surface. Each group consisted of 10 colored and 10 uncolored copings. Half of the copings (40) processed with a milling system according to the specific design were sent to be given a color (A3) through saturation in special dye by a manufacturing company. Just after sintering, the marginal discrepancies of copings were measured on the buccal, lingual, mesial and distal surfaces of metal die, under a Video Microscope System (sv-35, Sometech, Seoul, Korea) at a magnification of x100. It was remeasured after the adjusting of the inner surface. Next, all copings were luted to the metal dies using reinforced cement {GC FujiCEM (GC Corp. Tokyo, Japan)} and mounted on the testing jig in a Universal Testing Machine (Instron 4467, Norwood, MA, USA). The results were analyzed statistically using the one-way ANOVA test. RESULTS: The obtained results were as follow: 1. The measured value of marginal discrepancy right after sintering was the greatest in the contraction of the buccal area in all groups, except for group I2. 2. There was no significant difference of marginal fitness among the groups in the colored zirconia group (P<.05). 3. When the marginal fitness among the groups in the uncolored zirconia group was considered, group II2 had the smallest marginal discrepancy. 4. When the colored and uncolored groups with the same design were compared, there was a significant difference between I1 and II1 groups. In group 2, 3, and 4, the uncolored zirconia had the greatest marginal fitness (P<.05). 5. After adjustment of inner surface, there was no significant difference in the marginal fitness in all groups when color and design of the zirconia coping were compared. 6. The fracture load of CAD/CAM zirconia copings showed significant difference in group 1, 2, 3, and 4. I4 and II4 had the strongest fracture load. 7. When groups with different color and same design were compared, all colored groups showed greater fracture load (P>.05), with no significance. CONCLUSION: There was difference in the marginal fitness according to the design and coloration of zirconia copings right after sintering, but it was decided that the copings may well be used clinically if the inner surface are adjusted. The copings should be thick enough for the reinforcement of fracture strength. But considering the esthetics of the visible surfaces (labial and buccal surface), the thickness of copings may be a little thin, without giving any significant effect on the fracture strength. This type of design may be considered when giving priority to preservation of tooth or esthetics.

OBJECTIVES: Metabolic syndrome components, insulin resistance and central obesity cause type 2 diabetes and hypertension. This will increase the risk of cardiovascular disease. Women after menopause are at increased risk of metabolic syndrome. Several researchers studied that in menopause, metabolic syndrome increased cardiovascular mortality. We studied the impact on cardiovascular mortality of postmenopausal women with metabolic syndrome in the Republic of Korea. METHODS: Twenty four thousand nine hundred forty nine postmenopausal women aged 40 years or older were enrolled at health promotion centers of national university hospital located in 18 regions during 1994-2004. Age, weights, height, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), cholesterol, triglyceride (TG), high-density lipoprotein were evaluated and history taking about alcohol consumption, smoking, and exercise was performed. In addition, subjects who died of cardiac disease were analyzed from January 1995 to December 2009. RESULTS: Metabolic syndrome was higher in postmenopausal women with increased in age, BMI, blood pressure (BP), FBG, cholesterol, TG. Thirty cardiac deaths occurred during the observation period. Factors affecting cardiac death were age, smoking, FBG and when age and smoking were controlled. FBG was an important factor affecting cardiovascular mortality in our study. When controlling age, smoking, and alcohol consumption, metabolic syndrome caused an increased relative risk of cardiovascular mortality. Survival rate was much lower in postmenopausal women with metabolic syndrome than those without metabolic syndrome. CONCLUSION: Metabolic syndrome in Korean postmenopausal women increased cardiovascular mortality.

PURPOSE: The purpose was to compare the marginal fidelity and the fracture resistance of the zirconia crowns according to the various coping designs with different thicknesses and cement types. Material and METHODS: Zirconia copings were designed and fabricated with various thicknesses using the CAD/CAM system (Everest, KaVo Dental GmbH, Biberach., Germany). Eighty zirconia copings were divided into 4 groups (Group I: even 0.3 mm thickness, Group II: 0.3 mm thickness on the buccal surface and the buccal half of occlusal surface and the 0.6 mm thickness on the lingual surface and the lingual half of occlusal surface, Group III: even 0.6 mm thickness, Group IV: 0.6 mm thickness on the buccal surface and the buccal half of occlusal surface and the 1.0 mm thickness on the lingual surface and the lingual half of occlusal surface) of 20. By using a putty index, zirconia crowns with the same size and contour were fabricated. Each group was divided into two subgroups by type of cement: Cavitec(R) (Kerr Co, USA) and Panavia-F(R) (Kuraray Medical Inc, Japan). After the cementation of the crowns with a static load compressor, the marginal fidelity of the zirconia crowns were measured at margins on the buccal, lingual, mesial and distal surfaces, using a microscope of microhardness tester (Matsuzawa, MXT-70, Japan, x100). The fracture resistance of each crown was measured using a universal testing machine (Z020, Zwick, Germany) at a crosshead speed of 1 mm/min. The results were analyzed statistically by the two-way ANOVA and oneway ANOVA and Duncan's multiple range test at alpha= .05. RESULTS: Group I and III showed the smallest marginal fidelity, while group II demonstrated the largest value in Cavitec(R) subgroup (P < .05). For fracture resistance, group III and IV were significantly higher than group I and II in Cavitec(R) subgroup (P < .05). The fracture resistances of Panavia-F(R) subgroup were not significantly different among the groups (P > .05). Panavia-F(R) subgroup showed significantly higher fracture resistance than Cavitec(R) subgroup in group I and II (P < .05). CONCLUSION: Within the limitation of this study, considering fracture resistance or marginal fidelity and esthetics, a functional ceramic substructure design of the coping with slim visible surface can be used for esthetic purposes, or a thick invisible surface to support the veneering ceramic can be used depending on the priority.

We analysed retrospectively pharmacokinetic parameters of gentamicin and amikacin in 44 and 58 Korean pediatric patients, respectively, with normal renal function. Pharmacokinetic parameters were calculated from two concentrations in serum by method of Sawchuck. There was wide individual variation in peak serum concentrations of gentamicin and amikacin, Administration of the usually recommended doses yielded subtherapeutic concentrations in 47% and 82%, respectevely, of patients in the peak concentrations of gentamicin and amikacin. The volumes of distribution of gentamicin and amikacin in children of over 1 year of age were 0.37+/-0.13L/kg and 0.41+/-0.13L/kg which are greater than those reported from the western countries. We conclude that the wide individual variation and high frequency of subtherapeutic levels in the peak concentrations of gentamicin and amikacin obtained by usually recommended dosage as well as the narrow safety margin of these drugs necessitate monitoring of serum concentration and adjustment of individual dosage regimen early in the course of treatment with aminoglycosides.

Tetanus is rare in Korea due to the introduction of vaccination programs and the advancement in public health. Its common signs are trismus, voice disturbance, neck stiffness, and difficulty in swallowing, etc. A 56 years old man was injured by grasping a high voltage electric cable. After the accident, he fell down on a steel plate and had a head trauma. When he visited Emergency Department, there was multiple electric burn wound on left arm and left facial area. He was hospitalized on a department of neurosurgery, because intra cranial hemorrhage was presumed. 12 days later, he was referred to department of OMFS with developed painful masseter spasms and trismus. That night he violently bit his tongue with his denture. Because masseter muscle and temporal muscle constriction was involuntary, tongue was lacerated and denture was distorted. At first we supposed that the symptom was related with neurologic disturbance following head trauma or electric shock. But it was revealed that trismus was caused by tetanus on an electrophysiological test. By using mechanical ventilation and administration of tetanus immunoglobulin, muscle-relaxant, and sedatives at ICU, symptoms had subsided (4-weeks). Because tetanus is rare disease, we rarely suppose tetanus infection to be a cause of a trismus. Especially it is more difficult to diagnose in patient who has head trauma, burn and neurologic problem as in this case.

The levonorgestrel-releasing intrauterine system (LNG-IUS) is a highly effective contraceptive method that has several noncontraceptive benefits. It has been used in various gynecological conditions, such as heavy menstrual bleeding, dysmenorrhea, and endometrial hyperplasia. During the perimenopausal period, hormonal fluctuations occur, and there is a high tendency for the development of several benign gynecologic diseases. Therefore, the use of LNG-IUS in perimenopausal women might be more beneficial than in women belonging to other age groups. Moreover, the insertion of LNG-IUS during the perimenopausal period could confer endometrial protection during estrogen replacement therapy. In this review, we discuss the use of LNG-IUS in perimenopausal women.
