The main trend moves towards early excision and skin grafting as treatment for the deep second degree burns and the third degree burns. The ability to excision & skin grafting. This study prospectively evaluated the ability of laser doppler flow measurements obtained within 72 hours after burn injury to predict the depth of burn wounds. A Periflux system 4001 laser doppler flowmetry had been used to measure cutaneous microflow circulation of 100 selected points of burn wounds in 44 admitted patients from March 1993 to February 1994. The mean value of superficial second degree burn checked by laser doppler was 194.6 perfusion unit(PU). The deep second degree burn was 59.7 PU and third degree burn was 5.1 PU. The blood flow of more than 100 PU reliably predicted the superficial second degree burn with 90.2 percents accuracy. The blood flow between 100 PU and 10 PU predict the deep second degree dermal burn with 96.2 percents accuracy. That of less than 10 PU predict the third degree burn with 100 percents accuracy. There was also a significant correlation between initial flow measurements and the depth of burn wounds. We conclude that laser doppler flow measurements performed early after burn injury are useful in predicting the depth of burn wounds. The laser doppler flowmetry has the advantage of being easy to use, noninvasive, provide immediate result for early determination of burn depth. The laser doppler flowmetry is useful in selecting patients for early excision and grafting of burn wounds.

PURPOSE: The objective of this study was to evaluate and compare the accuracy of impression body taking by the closed and the open tray impression technique with 3 types of impression tray. Individual tray, metal stock tray and polycarbonate tray were used. MATERIALS AND METHODS: Nine closed tray impressions were taken by individual tray, metal stock tray and polycarbonate stock tray, respectively with polyether impression material. 9 open tray impressions were also acquired by same manner. Precision analysis on the master models was performed by attaching the reference frameworks with alternate single screws and measuring the vertical fit discrepancy of respective analogues in working cast with a stereo microscope. Data were analyzed by 1 way ANOVA and independent t-test. RESULTS: The average fit accuracy of impression bodies was calculated. With the closed tray impression technique, there were significant statistical differences in vertical fit discrepancy according to the types of tray. The individual tray group showed the lowest value and the polycarbonate stock tray group represented the highest. With the open tray impression technique, there was no significant difference in vertical fit discrepancy. Significant statistical difference in vertical fit discrepancy was found between the open and the closed impression technique with the polycarbonate stock tray. CONCLUSION: From the results above, more precise impressions could be acquired by the rigid individual tray compared with the polycarbonate stock tray. It was hard to get consistent accuracy impressions by the closed tray impression technique with polycarbonate stock trays.

The juxtaglomerular cell tumor is a rare benign tumor which causes surgically correctable hypertension. We report a case of hypertension caused by juxtaglomerular cell tumor in a 17-year old man. He presented with hypokalemia, metabolic alkalosis and hyperreninemic hyperaldosteronism. Renal angiography showed no evidence of renal artery stenosis. Though no mass was suspected in renal angiography, CT scan showed a well demarcated mass, 3 cm in diameter, in the upper portion of left kidney, which was resected and diagnosed to be a juxtaglomerular cell tumor. After resection of the tumor, blood pressure was normalized with resolution of hypokalemia, metabolic alkalosis and hyperreninemic hyperaldosteronism.

Calcium channel blockers (CCBs) are very popular drugs to lower blood pressure (BP) without significant side effects. A 72-year-old man admitted for uncontrolled hypertension. He had history of hypertension, atrial fibrillation with slow ventricular response, angina, abdominal aortic aneurysm, and stage 3 chronic kidney disease. He had taken several anti-hypertensives, such as amlodipine 5 mg, perindopril 8 mg, and indepamide 1.5 mg. To control BP, nifedipine 120 mg was added. Then pulmonary edema and pleural effusion was developed. Echocardiography showed preserved left ventricular ejection fraction and mild mitral regurgitation. Fluid restriction and high dose furosemide did not cease pleural fluid accumulation. Thus a total of 4 times of thoracentesis were done and all fluid analyses revealed transudate. We thought that pleural effusion and pulmonary edema was induced by CCBs and discontinued the drugs. He recovered quickly and finally discharged in a stable condition.

This study aimed to assess the effects of different dialysate bicarbonate concentrations in correcting acid-base imbalance in 53 stable hemodialysis patients in a university-hemodialysis unit. Three different bicarbonate concentrations were assigned, i.e. 25 mEq/L in 10, 30 mEq/L in 30, and 35 mEq/L in 13 patients. Blood gas analyses from arterial line blood samples before and after dialysis in the mid-week were performed for the determination of pH and serum bicarbonate concentration ([HCO3-]). The mean values of predialysis arterial [HCO3-] were mildly acidotic in all 3 groups, but not significantly different among them, whereas those of post-dialysis arterial [HCO3-] were alkalotic, especially in the group of 35 mEq/L as compared with the other two groups. The mean blood pH was not significantly different among the 3 groups. As expected, there was a positive correlation between pre-dialysis pH and post-dialysis pH (r=0.45, p=0.001), and pre-dialysis [HCO3-] and post-dialysis [HCO3-] (r=0.58, p=0.000), but with a negative correlation between pre-dialysis [HCO3-] and the increment of intradialytic [HCO3-] following hemodialysis (r=-0.46, p=0.001). In conclusion, this study shows that the impact of conventional dialysate bicarbonate concentrations ranging from 25 to 35 mEq/L is not quite different on the mild degree of predialysis acidemia, but the degree of postdialysis alkalemia is more prominent in higher bicarbonate concentrations. Base supply by hemodialysis alone does not seem to be the main factor to determine the predialysis acidosis in end-stage renal disease patients on chronic maintenance hemodialysis.

BACKGROUND: This study was conducted to investigate risk factors for perioperative periods between general anesthesia (GA group) and thoracic epidural blockade combined with general anesthesia (CEA group) for consecutive hepatic resections. METHODS: A retrospective chart review was carried out regarding 85 patients who had undergone hepatic resections. We compared the effects of postoperative pain control in the two groups, including pulmonary complications and durations of hospital stay. RESULTS: There was no significant difference in demographic data between the two groups. The perioperative fluid requirement and transfusions were lower in the CEA group. Supplemental analgesics requirement was significantly lower in the CEA group than the GA group in the 3 days postoperatively. There were no statistical difference between the two groups in nausea, vomiting, urticaria, constipation or urinary retention, but hypotension was more pronounced in the CEA group than the GA group. Postoperative pulmonary and surgical complications were similar between the two groups, but the duration of hospital stay was longer in the GA group than the CEA group. CONCLUSIONS: We conclude that the thoracic epidural blockade combined with general anesthesia provided lower surgical blood loss and better postoperative analgesia and hospital stay than general anesthesia for hepatic resections.

Adenoma malignum (minimal deviation adenocarcinoma) is an extremely well-differentiated adenocarcinoma of uterine cervix. Despite its benign histological appearance, this tumor is thought to be malignant and has a poor prognosis. Because Pap smear and punch biopsy have low sensitivity, accurate diagnosis of the tumor may be difficult. If it is diagnosed, it must be treated same as in cervical cancer. We presented one case of preoperatively diagnosed adenoma malignum by deep cone biposy with a brief review of literature.

BACKGROUND: The influence of lifestyle diseases on postoperative complications and long-term survival in patients with non-small cell lung cancer (NSCLC) is unclear. The aim of this study was to determine whether lifestyle diseases were significant risk factors of perioperative and long-term surgical outcomes in elderly patients with stage I NSCLC. METHODS: Between December 1995 and November 2013, 110 patients aged 65 years or older who underwent surgical resection of stage I NSCLC at Dong-A University Hospital were retrospectively studied. We assessed the presence of the following lifestyle diseases as risk factors for postoperative complications and long-term mortality: diabetes, hypertension, chronic obstructive pulmonary disease, stroke, and ischemic heart disease. RESULTS: The mean age of the patients was 71 years (range, 65 to 82 years). Forty-six patients (41.8%) had hypertension, making it the most common lifestyle disease, followed by diabetes (n=23, 20.9%). The in-hospital mortality rate was 0.9% (n=1). The 3-year and 5-year survival rates were 78% and 64%, respectively. Postoperative complications developed in 32 patients (29.1%), including 7 (6.4%) with prolonged air leakage, 6 (5.5%) with atrial fibrillation, 5 (4.5%) with delirium and atelectasis, and 3 (2.7%) with acute kidney injury and pneumonia. Univariate and multivariate analyses showed that the presence of a lifestyle disease was the only independent risk factor for postoperative complications. In survival analysis, univariate analysis showed that age, smoking, body mass index, extent of resection, and pathologic stage were associated with impaired survival. Multivariate analysis revealed that resection type (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.08 to 4.49; p=0.030) and pathologic stage (HR, 1.89; 95% CI, 1.02 to 3.49; p=0.043) had independent adverse impacts on survival. CONCLUSION: This study demonstrated that the presence of a lifestyle disease was a significant prognostic factor for postoperative complications, but not of survival, in elderly patients with stage I NSCLC. Therefore, postoperative complications may be influenced by the presence of a lifestyle disease.
