BACKGROUND: The diagnostic methods of atherosclerosis before the development of clinical diseases(such as angina pectoris, myocardial infarction, cerebral infarction or peripheral vascular disease) are rather limited. The Russian doctors made the observations through the autopsy studies that there is a good correlation between the degree of atherosclersis or the cholesterol content of the aorta and the cholesterol content of the skin. We tried to investigate whether there is a significant degree of differences in the cholesterol content of the skin between the patietns with atherosclerotic disease(disease group), the patients who have not developed the clinical atheroscleric disease but have risk factors for atherosclerosis(risk group), and the normal control patients(normal group). METHODS: The skin choleterol was extracted from the palm of the hands by the closed contact with the chemicals. RESULTS: 1) The skin cholesterol was 2.77+/-1.08/microg/cm2in the disease group, 2.47+/-1.13microg/cm2in the risk group, and 1.84+/-0.60microg/cm2in the control group, The difference between the disease group and the normal group was significant(p<0.001), but the difference between the disease group and the risk group was not significant. 2) When the skin cholesterol of 2.1microg/cm2was used as a criterion. its sensitivity and specificity to predict either the disease gorup or the risk group was 66.1% and 70.8%. 3) In addition to the skin cholesterol of 2.1microg/cm2or more, if we add a criteria of cholesterol >220mg/dl, or TC/HDL-C ratio >4:1, or Apo B/A ratio >0.9, these separated the normal group from either the disease group or risk group much beter. 4) There was no significant correlation between the skin cholesterol and blood cholesterol. Also there were not any significant correlations between the skin cholesterol and the LDL cholesterol, TC/HDL-C ratio or Apo B/A ratio. CONCLUSION: On the basis of the above mentioned observations made by the Russian doctors and the present data showing significantly higher skin cholesterol level in the disease and risk group compared with normal control group, and little significant correlation between the skin cholesterol and the blood cholesterol level, it is likely that the skin cholesterol can be considered as an independent risk index for the atherosclerotic disease. Measuring the skin cholesterol by extraction of cholesterol from the palms of the hands may help predicting the presence or the risks of the atherosclerotic diseases.

Pulmonary histiocytosis X is a rare granulomatous disorder of unknown etiology that alters the interstitium of the lung. When confined to the lung, it is known as primary pulmonary histiocytosis X or eosinophilic granuloma of the lung. The chest radiograph shows characteristic nodular, reticular, and cystic abnormalities, which are most apparent in the upper and middle lung zones, but spare the costophrenic angles, The CT demonstrates innumerable small cysts with thin walls, and fine nodules. Recently we experienced pathologically proven primary pulmonary histiocystosis X in 35 years old male patients who had recurrent pneumothorax.

PURPOSE: Nutritional as well as genetic and hormonal factors play an important role in the bone mineralization during childhood and adolescence. There are several physical and metabolic changes in obese children, and these changes may influence on the mineralization of the skeleton. The studies about bone mineralization of obese children are rare and contradictory. This study was performed to evaluate the influence of childhood obesity on bone mineral density(BMD). METHODS: The BMD of 49 obese and 41 non-obese children were measured at lumbar spines(L2-L4) using dual energy X-ray bone absorptiometry. Then, the results were assessed and compared according to the degree of obesity and pubertal sex maturation. RESULTS: There were no significant differences in BMD between obese children and non-obese children(0.87+/-.19 g/cm2 vs 0.81+/-.13 g/cm2). BMD increased according to the Tanner' pubertal staging, and the most marked increment was observed at overt puberty. No sex difference in BMD was seen in both obese and non-obese children. BMD was highly correlated with age, height, weight and body mass index(BMI), but there was no significant correlation between BMD and osteocalcin. CONCLUSION: BMD of obese children was not significantly different from that of non-obese children, and BMD also was not changed according to the degree of obesity. These findings suggest that BMD is not influenced by obesity in children.

To compare the advantage and disadvantage of isobaric and hyperbaric tetracaine spinal anesthesia, ninety, either sex, adult patients scheduled for knee arthroscopy were assigned randomly into two groups; one with the isobaric (n=70), and the other with the hyperbaric (n=20) tetracaine spinal anesthesia. The isobaric solution was prepared to 0.5% tetracaine in 50% cerebrospinal fluid of the patient's own and the hyperbaric solution to 0.5% tetracaine in 5% dextrose in water. Epinephrine was mixed to either solution in the ratio of 1: 200,000. The dosage of tetracaine was determined by the patient's height; 0.1 mg/cm height-difference, added or reduced to the reference dose of 12 mg/160cm. The site of lumbar puncture was L2-3 intervertebral space and 22 G Quincke spinal needle used. The speed of injection was fixed to the rate of 1 ml/10 sec. The onset, duration and maximal anesthetic level (MAL) in both groups were not significantly different and blood pressure and heart rate decreased with the elapsed time during anesthesia in similar pattern in both groups. And also, there was no significant difference in postspinal anesthetic complications such as headache, hypotension, etc. In conclusion, there was no significant difference in clinical aspects between hyperbaric and isobaric tetracaine spinal anesthesia for knee arthroscopy, with corresponding doses and strength of tetracaine, technics in room temperature.

BACKGROUND: More than 70% of morbidity and mortality of diabetes mellitus is due to macrovascular complications. These complications may be associated with defect of endothelium-dependent vascular relaxation. There have been suggestions that this defect might be due to direct toxicities of oxygen-free radical. So in this study ascorbic acid was used as a dietary supplement in streptozotocin induced diabetic rats to correct this defect. MATERIAL AND METHOD: Sixty male Sprague-Dawley rats were used in this study. They were divided into control and experimental groups. Streptozotocin was injected to the 33 rats of experimental group and then divided into two the other receiving subgroups; one receiving ascorbic acid supplement(1 g/l in drinking water); and nosupplements. At 6, 9 and 12 weeks, abdominal aortic rings were obtained to make tissue preparations for evaluation of vascular smooth muscle contractility. RESULT: While control group showed good response to acetylcholine induced relaxation, diabetic group showed decreased relaxation regardless of ascorbic acid supplement at the experiments 6 weeks after streptozotocin treatment. This abnormal endothelium-dependent vascular relaxation was markedly reversed at 9 and 12 weeks into the diabetic group with ascorbic acid supplement. There were no differences in sodium nitroprusside induced relaxation responses between control and experimental groups; also, norepinephrine induced contractile responses did not show any remarkable effects. CONCLUSION: These results strongly suggest that the endothelial cells have defects in diabetic rats. Dietary supplement of ascorbic acid can reverse the defects of diabetic endothelial cells through its antioxidant effects and it may further protect against vascular disease in diabetic patients.

OBJECTIVE: Patient-controlled-analgesia (PCA) using intravenous (IV) opioids is recognized a safe and effective method for pain control. However, postoperative analgesia with opioids is associated with a high incidence of postoperative nausea and vomiting (PONV) exceeding 30%. The 5-hydroxytryptamine receptor 3 (5-HT3) antagonists alleviate nausea and vomiting. This study aims to compare the effectiveness of ramosetron and ondansetron in preventing PONV following laparoscopic hysterectomy for benign uterine diseases under general anesthesia. METHODS: The medical records of 1483 patients who underwent laparoscopic hysterectomy between January 2005 and May 2009 were reviewed. Of the 1483 patients, 1184 patients who received IVPCA with ramosetron 0.3 mg (n=761) or ondansetron 8 mg (n=423) were analyzed. Fentanyl-based IVPCA was administered for 48 hours after surgery. The overall incidence of postoperative nausea and vomiting, bowel ileus, Levin tube insertion for severe bowel ileus, additional usage of pain killers and discontinuation of the IVPCA infusion with PCA-related severe nausea and vomiting were assessed for 48 hours after surgery. The amount of time until bowel gas passage resumption after surgery was measured. RESULTS: There was a significant difference between the two groups regarding the duration until post-operative bowel gas passage resumption (1.78+/-0.79 days in the ramosetron group, and 2.23+/-0.83 days in the ondansetron group; p=0.005); however, there were no significant differences found in other aspects. CONCLUSION: Ramosetron is superior to ondansetron in terms of faster recovery in bowel mobility, with similar effects in preventing the incidence of PONV.

Prenatal ultrasonographic appearance and Doppler characteristics of extracranial masses are variable, depending on the location, vasculature, amount of arteriovenous shunting, and degree of proliferation. Epidermoid cysts are found in a variety of locations around the skull and midface. They are thought to occur as a result of the persistence of ectodermal elements at sites of suture closure, neural tube closure, and diverticulation of the cerebral hemispheres. They contain ectoderm but no skin element. We experienced 33-year-old primigravida with fetal extracranial mass at 23 weeks gestation. We presumed that this extracranial mass was hemangioma. However, the mass was suspected as scalp epidermoid cyst on postnatal ultasonography.

Warfarin is an oral anticoagulant which is known to cross the placenta causing birth defects, known as warfarin embryopathy; fetal effects of early gestational exposure to warfarin is known to cause marked nasal hypoplasia, rhizomelia, and stippled epiphyses. The period of greatest sensitivity is 6 to 9 weeks of gestational age. Clinical studies have suggested that discontinuing warfarin before 6 weeks of gestational age could avoid the teratogenic effect. We experienced a women who had been taking warfarin for 15 years because of SLE (Systemic Lupus Erythematosus) and CRF (Chronic renal failure), who was found to be pregnant at 9 weeks of gestation. She discontinued warfarin and started heparin treatment, however the ultrasound examination showed shortened long bone, scalp edema, and cardiac anomaly (Ventricular septal defect), and termination of pregnancy was performed at 17 weeks of gestation. We report a case of warfarin embryopathy resulting from warfarin exposure until 9 weeks of gestation with a brief review of literature.

PURPOSE: The healing process following tooth extraction apparently results in a pronounced resorption of the alveolar ridge. As a result, the width of alveolar ridge is reduced and severe alveolar bone resorption occurs. The purpose of this experiment is to clinically and histologically evaluate the results of using horse-derived bone mineral for socket preservation. METHODS: The study comprised 4 patients who were scheduled for extraction as a consequence of severe chronic periodontitis or apical lesion. The extraction was followed by socket preservation using horse-derived bone minerals. Clinical parameters included buccal-palatal width, mid-buccal crest height, and mid-palatal crest height. A histologic examination was conducted. RESULTS: The surgical sites healed uneventfully. The mean ridge width was 7.75 +/- 2.75 mm at baseline and 7.00 +/- 2.45 mm at 6 months. The ridge width exhibited no significant difference between baseline and 6 months. The mean buccal crest height at baseline was 7.5 +/- 5.20 mm, and at 6 months, 3.50 +/- 0.58 mm. The mean palatal crest height at baseline was 7.75 +/- 3.10 mm, and at 6 months, 5.00 +/- 0.82 mm. There were no significant differences between baseline and 6 months regarding buccal and palatal crest heights. The amount of newly formed bone was 9.88 +/- 2.90%, the amount of graft particles was 42.62 +/- 6.57%, and the amount of soft tissue was 47.50 +/- 9.28%. CONCLUSIONS: Socket preservation using horse-derived bone mineral can effectively maintain ridge dimensions following tooth extraction and can promote new bone formation through osteoconductive activities.

OBJECTIVE: Several studies have reported on the effectiveness of fronto-lateral craniotomy in reducing the operating time and post-operative complications. However, no study has practically evaluated this method from the cosmetic point of view. MATERIALS AND METHODS: We designed this study for comparison of the clinical differences and cosmetic outcomes between the frontolateral craniotomy and the conventional pterional craniotomy for clipping of unruptured intracranial aneurysms. We performed a retrospective analysis of the two groups based on their medical records and radiologic findings juxtaposed with their length of hospital stay, intensive care unit day and operation time, and the emergence of postoperative complication, mean size of aneurysm, and temporal depression. RESULTS: After careful comparison of the thickness of temporalis muscle between the craniotomy side and the contralateral side, the results clearly showed that the conventional pterional craniotomy group was asymmetric by a p value of 0.152 and the frontolateral craniotomy group was symmetric by a p value of 0.002. CONCLUSION: Frontolateral craniotomy could be a practical alternative for patients with an unruptured intracranial aneurysm in the anterior circulation including the posterior communicating artery, particularly those who are in a medically poor state or who highly demand minimal aesthetic mutilation.
