Although platelet have been implicated in the pathogenesis of the thrombotic disease, the platelet aggregability was not well studied in Korea. Author measured platelet aggregability in 103 clinical cases including 30 healthy volunteers to evaluate the platelet function and the effect of Aspirin and Dipyridamole on aggregability in Korean. 24 patients with cerebral thrombosis, 24 patients with ischemic heart disease and 25 patients with hypercholesterolemia were included for this study. Aggregation tests were performed at three final concentrations of epinephrine(10microM/L) and ADP(4 microM/L, 10 microM/L) with platelet aggregometer which was made by Chrono-Log Corp. in all cases. Platelet aggregations were measured in patients who were treated with Aspirin, Dipyridamole and combined treatment of Aspirin and Dipyridamole respectively. The following results were obtained. 1) The mean maximal platelet aggregability in the normal subjects induced by 10 microM/L epinephrine was 59.3+/-24.26%, 66.6+/-14.00% in Bm and 62.5+/-19.30% in B5 in induction by 4 microM/L ADP, and 77.2+/-8.99% in Bm and 76.6+/-9.83% in B5 in induction by 10microM/L ADP. 2) The mean maximal platelet aggregability in patients with cerebral thrombosis induced by 10 microM/L epinephrine was 89.2+/-7.33%, 78.8+/-9.41% in Bm and 78.5+/-9.93% in B5 in induction by 4 microM/L ADP, and 86.4+/-7.69% in Bm and B5 in induction by 10 microM/L ADP. The results showed significantly elevated platelet aggergability than that of normal subjects(p<0.01). 3) The mean maximal platelet aggregability in patients with ischemic heart disease induced by 10 microM/L epinephrine was 88.1+/-11.99%, 78.2+/-12.50% in Bm and B5 in induction by 10 microM/L ADP. The results showed significantly elevated platelet aggregability than that of normal subjects(P<0.01). 4) The mean maximal platelet aggregability in patients with hypercholesterolemia induced by 10 microM/L epinephrine was 86.8+/-15.99%, 82.7+/-11.19% in Bm and 82.0+/-12.87% in B5 in induction by 4 microM/L ADP, and 88.5+/-11.47% in Bm and B5 in induction by 10 microM/L ADP. The results showed signifcantly elevated platelet aggregability than that of normal subjects(P<0.01). 5) The mean maximal platelet aggregability in patients with thrombotic disease was studied by Dipyridamole administration. The platelet aggregability induced by epinephrine before administration was 90.9+/- 8.52% and after administration it was 78.9+/-15.68%, and the results showed that Dipyidamole lowered aggregability significantly. The platelet aggregability induced by 4 microM/L ADP before administration was 84.0+/-11.90% in Bm and B5 and after administration it was 78.0+/-11.44% in Bm and B5, and the results showed that Dipyridamole lowered aggregability but not significant. The platelet aggregability induced by 10 microM/L ADP before administration was 89.2+/-10.39% in Bm and B5 and after administration it was 80.5+/-8.44% in Bm and B5, and the results showed that Dipyridamole lowered aggregability significantly. 6) The mean maximal platelet aggregability in patients with thrombotic disease was studied by Aspirin administration. The platelet aggregability induced by epinephrine before administration was 91.0+/-4.79% and after administration it was 47.6+/-17.72%. The platelet aggregability induced by 4 microM/L ADP before administration was 84.6+/-10.37% in Bm and B5 and after administration it was 72.6+/-11.85% in Bm and 65.3+/-15.97% in B5. The platelet aggregability induced by 10 microM/L ADP before administration was 84.9+/-6.30% in Bm and B5 and after adminstration it was 77.7+/-8.60% in Bm and 75.0+/-8.89%. The results showed that Aspirin lowered aggregability markedly. 7) The mean maximal platelet aggregability in patients with thrombotic disease was studied by combined administration of Aspirin and Dipyridamole. The platelet aggregability induced by epinephrine before administration was 86.7+/-13.77% and after administration it was 36.7+/-14.01%. The platelet aggregability induced by 4 microM/L ADP before administration was 81.5+/-12.93% in Bm and 80.6+/-14.15% in B5 amd after administration it was 54.7+/-17.27% in Bm and 44.6+/-21.17% in B5. The platelet aggregability induced by 10 microM/L ADP before administration was 87.8+/-10.11% in Bm and B5 and after administration it was 65.7+/-13.59% in Bm and 62.0+/-16.42% in B5. The results showed that combined administration of Aspirin and Dipyridamole lowered aggregability significantly and the results were lower than that of normal subjects. 8) The effects of combined treatment of Aspirin and Dipyridamole showed marked reduction of platelet aggregability than that of single treatment of Aspirin or Dipyridamole in thrombotic disease.

Chronic mucocutaneous randidiasis is a clinical syndrome characte ized by chronic and reccurent superficial candidal infection of the skin, mucous membranes, and nails. This syndrome is frequently associated with immune deficiency or endocrinopathy, especially hypopar; thyroidism. We report a case of chrcinic mucocutaneous candidiasis associated with hypoparathyroidism in a 8- year-old girl.

BACKGROUND: Scapular notching can happen at diverse location depending on implant design or operative technique, therefore, it is easily misdiagnosed. Thus, this study purposed to suggest a method helpful to assess scapular notching. METHODS: The subjects were 73 cases of reverse shoulder arthroplasty (RSA) for cuff tear arthropathy during the period from May 2009 to April 2014 and followed-up for over a year. There was medialized RSA in 22 cases, bone increased offset RSA (BIO-RSA) in 36 cases, and metal increased offset RSA (metal-RSA) in 15 cases. Scapular notching was not determined by bone defect at the inferior of glenosphere as Sirveaux's classification, but scapular notching at the site where the rotational route of the polyethylene of humeral implant met the scapular neck were examined. The results were compared with conventional method. RESULTS: By conventional method, scapular notching was observed in 10 cases (45.5%) in medialized RSA, 12 cases (33.3%) in BIO-RSA, and none in metal-RSA. By new method, it was observed in 9 cases (40.9%) in medialized RSA, 10 cases (27.8%) in BIO-RSA, and none of metal-RSA. The site of scapular notching was apart from glenoshpere in 18 cases, and at inferior of glenosphere in 1 case. Absorption of bone graft was observed in 4 (11.1%) out of 36 cases of BIO-RSA. CONCLUSIONS: It is hard to distinguish scapular notching from absorption of bone graft in BIO-RSA, and bone absorption at the lateral lower end of glenoid in medialized RSA. Thus, it is considered useful to assess scapular notching at the site where the rotational route of the polyethylene insert meets scapular neck.

BACKGROUND: We assessed the accuracy of staging in evaluation of bronchial invasion thus found the role of CT in patients who underwent resective surgery in primary lung cancer. Materials and METHODS: Authors retrospectively analized the preoperative CT scans of 156 patients receiving pneumonectomy(n=95) and lobectomy(n=61). Among lobectomy patients 7 patients subsequently performed pneumonectomy because of positive resection margin of bronchus in frozen biopsy. We also retrospect lively analized CT scans of non-operated 60 patients who Performed sufficient bronchoscopic biopsy. Bronchial wall thickness more than 3mm, irregular wall thickening find reduction of diameter by CT were defined as bronchial invasion. The pathologic examination of resection margin were positive in 20, stump recurrence occurred in 6 of the operated group, and the pathologic examination of biopsy of bronchial wall were positive in 34 of the non operated group, and these were all regarded as bronchial invasion. RESULTS: The CT assessment of bronchial invasion revealed low sensitivity (11.5%), low positive predictability(38%), but high specificity(96%) and relatively high accuracy (84%) in the operated group and higher sensitivity (62%), higher positive predictability(95%) in non-operated group. CONCLUSION: In lung cancer patients who underwent operation CT showed very low sensitivity and positive predictability In evaluation of bronchial invasion Because the usefulness of CT in evaluation of bronchial invasion is limited, therefore aggressive fiberoptic bronchoscopic biopsy is thought to be necessary before surgical attempt.
