We report a case of cutaneous calcinosis following extravasation of calcium calcium chloride in a 3-week old neonate, After extravasation of 3% calcium chloride infusion, rapid and marked swelling, erythema, and signs of soft tissue necrosis developed over the extensor surface of both upper extremities. Through the small channels of the destroyed epidermis, tiny white pieces of calcific masses were eliminated spontaneously. Histologically the calcium deposits were found as amorphous masses in the upper dermis and the discharge of calcium deposits also took place by means of transepidermal elimination. The central bone formation and surrounding calcium deposition were present along with dense lymphohistiocytic cell infiltration in the deep dermis. Complications of extravasation of calcium solution during intravenous infusion included localized calcification and, ocasionally necrosis. The incidence of compllcations was about eight percent. This is a case which again emphasises of the danger of using calcium chloride intravenously in the neonate or young infant.

BACKGROUND: Our study aimed to make a comparative analysis of clinical outcomes of arthroscopic decompression for rotator cuff calcific tendinitis by location of calcific deposits and by its size. METHODS: We enrolled a total of 38 patients, comprising 39 affected shoulders, who underwent arthroscopic decompression for calcific tendinitis. As our clinical scores, we evaluated the UCLA, the ASES, and the VAS scores and analyzed them by calcific location, by calcific deposit size, by the presence or absence of calcific remnants, and by whether concomitant cuff repair was performed. RESULTS: The clinical scores of those whose calcific deposit had an area greater than 77.0 mm2 and of those whose calcific deposit had an area smaller than 77.0 mm2 did not significantly differ (p=0.21 in ASES; p=0.19 in UCLA; p=0.17 in VAS). Nor did the clinical scores significantly differ with respect to the location of calcification (p=0.23). Further, the clinical scores did not significantly differ between those who had calcific remnants and those who did not and between those who received additional cuff repair and those who did not. CONCLUSIONS: We found that the clinical outcomes after arthroscopic decompression of calcific tendinitis were not significantly associated with the cuff tendon in which the calcium deposits are found; the location of the calcium deposits in the supraspinatus tendon (if found in this tendon); the size of calcific deposits; the presence of calcific remnants; and concomitant cuff repairs.

Vanadate is a trace element in animal tissues and has been known to inhibit NA(+)-K(+) ATPase in various tissues including skeletal and cardiac muscles and smooth muscles. Vanadate shows contractile actions on various types of smooth muscles. Prolonged dietary administration of vanadate has been shown to cause arterial hypertension, increased peripheral resistance, and a marked reduction of coronary, visceral and renal blood flow.In isolated vascular smooth muscle of aorta, application of vanadate caused contraction. These studies have been conducted the preparation of vascular smooth muscles from which endothelial cell were removed. It has been reported that endothelial cell releases relaxing factor(s) (endothelium-derived relaxing factor, EDRF) in response to acetylcholine and a number of other stimuli and also produces vasoconstrictor substances (endothelium-derived contracting factor, EDCF). The aim of this present experiment is to elucidate whether vascular response of isolated rabbit aorta induced by vanadate are endothelium dependent or not. The result obtained were summarized as follows ; 1) When endothelium was intact, vanadate induced vascular relaxation of aorta precontracted with norepinephrine. But K+ induced contraction was augmented by vanadate in the aorta with or without endothelium. Whereas relaxation produced by vanadate precontracted with angiotensin II was endothelium-independent. 2) Hemoglobin, methylene blue, hydroquinone, and verapamil inhibited vanadate-induced vascular relaxation. But indomethacin and quinacrine had no effect on vanadate induced vascular relaxation. From the above results, it is speculated the vanadate act on endothelium, modifies the synthesis or release of endothelium-dependent relaxing factor and thus changes the contractile responses to norepinephrine in rabbit aorta.

BACKGROUND: Despite improvement of mortality in acute myocardial infarcrtion, high mortality rate associated with cardiogenic shock remains essentially unchanged. We have reviewed our result of coronary intervention in 15 patients and found relative survival advantage. METHODS: Between Sep. 1992 and Aug. 1995, 15 consecutive patients(M. 10, F. 5) with cardiogenic shock in acute myocardial infarction were treated with coronary intervention using ballon PTCA. IABP was inserted in all patients prior to PTCA. RESULTS: 1) Most commonly found infarct related artery was left anterior descending artery(11) followed by right coronary artery(3) and left main coronary artery(1). 2) Successful reperfusion rate was 86.7%(13/15), and in-hospital mortality rate was 26.7%(4/15). 3) In-hospital mortality was higher in elderly patients compared with less than 70yaer old patients(0%(0/11)vs. 75.0%(3/4)(P < 0.05). 4) Mortality rate was lower in single vessel disease than multivessel disease(11.1%(1/9) vs. 50%(3/6) p<0.05). CONCLUSION: Although this study is uncontrolled, the date suggest that urgent coronary intervention for improving coronary perfusion may reduce mortality of acute myocardial infarction complicated by cardiogenic shock, particularly with single vessel disease and young age group.

To evaluate the influencing factors on pulmonary venous flow(PVF) pattern, we studied the relationship between PVF and left ventricular ejection fracton(EF), mitral annulus motion(MAM) and transmitral flow using pulsed doppler echocardiography in patients with dilated cardiomyopathy(DCMP), acute myocardioal infarction(AMI), left ventricular hypertrophy(LVH) and atrial fibrillation(AE). Ther results were as follows : 1) In the normal controls(13 cases), two forward flow during ventricular systole(VS) and diastole(VD) and one retrograde flow during atrial systole(AS) were observed. The peak velocity of VS, VD and AS flow was 45.9cm/s, 42.8cm/s and -18.3cm/sec, respectively. The peak VS/VD ratio was 1.1. 2) In patients with DCMP(11 cases), (a) compared to the noraml subjects, the peak velocity of VS flow and VS/VD ratio were were significantly reduced(p<0.005 and p<0.001, respectively) and were positively correlated with ejection fraction(r=0.8 and r=0.7, respectively) (b) in 2 DCMP cases with severe mitral regurgitation, systolic retrograde flow was observed in the pulmonary vein instead of forward VS flow. 3) In 12 AMI cases and 7 LVH cases with normal or slightly diminished left ventricular systolic function but with abnormal diastolic function. (a) the peak velocity of VS flow and peak VS/VD ratio were significantly increased(r<0.005 and p<0.01, respectively). (b) the peak velocity of VD flow is positively correlated with transmitral E/A ratio(r=0.8) and the peak VS/VD ratio was positively correlated with transmitral pressure half time(r=0.8). (c) the peak velocity of retrograde AS flow was significantly increased(p<0.001). (d) there was no correlation between doppler parameters of PVF and left ventricular ejection fraction. 4) In patients with atrial fibrillation(10 cases), VS flow was markedly diminished or absent and only VD flow was observed. Also, retrograde AS flow was not observed. These findings suggest that the pattern of PVF is influnced by LVEF, MAM, transmitral inflow and atrial contraction. However, main contributary factors in determining the pattern of PVF in each disease are diverse according to its main pathophysiology.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

Rahnella aquatilis, an infrequently isolated gram-negative rod, is the only species of the genus Rahnella within the Enterobacteriaceae family. The organism's natural habitat is water, from which most isolates have been recoverd. Infecions in humans have only occasionally been reported, especially in immunocompromised patients. We reort a case of bacteremia caused by this organism in a hemodialysis patient.

BACKGROUND: Epidermal cyst is a common disease. The clinical and histo pathologic findings in patients with epidermal cysts are described. OBJECTIVE: Our purpose is to identify the clinical and histopathologic feastures of epidermal cysts. MEHTODS: We ealuated the clinical and histopathologie features of 11 cases which were diagnosed with epidermal cysts at the department of dermatology in Wonju Chist.an Hospital and Jeju Severance Dermatologic clinic for 13 years, from January 1980 to June 1992. RESULTS: The ratio of males to females was 1.9: 1 with male predominance. Age distribution at first visit was variable, ranging from to 85 years old. The mean age was 3.5 years old. The Duration of lesions was variable, ranging from a 3 days to 20 years, with the mean duration of 2.4 years. The most common site of lesions was the face(36%), followed by the trunk(18%), neck(13%), leg(13%), arm (8%), scalp(3%), scrotum(3%), vagina(3%), palm(1%) and fingers(1%). Histopathologically, 46 cases(41%) were ruptured. The most common stromal change was fibrosi followed by granulation tissue formation, giant cell, calcifiration, pilomatricoma like change, pigment, squamous eddy, bone formation and vessel proliferation. The most common cystic content was keiatinous material followed by parakeratotic cell, bacterial colony, calcification, cholesterol cleft, pigment and RBC. The most common cystic wall change was acanthosis followed by atrophy, hyperplasia, hyergranulosis, basalioma like change, parakeratosis and reticulation. CONCLUSION: Epidermal cysts are slowly growing tumors. They occur nost commonly on the face, trunk, neck, legs and arms. Histopathologically, they have a wall compose 1 of true epidermis. When an epidermal cyst ruptures, a foreignbody reaction with numerous multinu leated giant cells occurs.

Bone marrow contains mesenchymal stem cells capable of differentiating into osteoblastic lineage. To test the ability of purified bone marrow mesenchymal cell loaded onto xenograft with type I collagen gel to heal bone defect, mesenchymal stem cells were isolated from bone marrow of Lewis rat, and culture-expanded. Northern blot hybridization revealed that osteocalcin and osteopontin mRNA expression persisted for 8 weeks of in-vitro culture. When the bone marrow mesenchymal cells became 80-90% confluent in 2-3 weeks, they were loaded onto chips of xenograft (Lubboc(R) with type I collagen gel. The cell-gel-xenograft composite was transplanted subcutaneously into the dorsum of nude mice. It was also transplanted into tibial diaphyseal defect made in syngeneic Lewis rats, and compared with the control group where only the xenograft was planted. There was no ectopic bone formation at the dorsum of nude mice around the transplanted cell-gel-xenograft complex. In the long bone defect model, the cell-gel-xenograft group induced fibrosis around it and the bone healing was inferior to the control group. Type I collagen gel is not a suitable carrier of bone marrow mesenchymal cells to heal the long bone defect.
