Anti-thrombin III deficiency is known as a disease of autosomal dominant trait and relatively common, but in Korea, exact incidence and mortality is not known, In general, Anti-thrombin III deficiency is expressed to venous thromboembolism like deep vein thrombosis or pulmonary embolism. But, arterial embolism is very rare. We experienced a case of Antithrombin III deficiency expressed as myocardial infarction of inferior wall by huge thrombosis in the mid and distal right coronary artery.

PURPOSE: Management of major renal injury caused by blunt trauma is still somewhat controversial. We investigated the characteristics of grades IV and V blunt renal injury patients who underwent conservative or operative treatment, and determined the feasibility of conservative treatment of such injury. MATERIALS AND METHODS: We retrospectively reviewed the records of 25 patients who presented our hospital with grades IV or V blunt renal injury. The 10 patients treated conservatively were assigned to group 1, and the 15 patients treated surgically to group 2. Each group was compared with respect to initial evaluation, radiologic findings, associated injuries, duration of hospital and intensive care unit stay, transfusion requirements, complications and follow-up imaging. RESULTS: We found that shock was the only characteristic sign of the surgical treatment group and that the degree of hematuria did not correlate with treatment options. Radiologic findings which differed significantly between the 2 groups were the proportion of devitalized segments to total renal parenchyma and the presence of ureteral opacification despite urinary extravasation. Patients in group 1 had lower transfusion requirements but longer hospitalization, both significantly. Follow-up imaging of group 1 patients revealed functioning renal parenchyma with resolution of retroperitoneal hematoma in 8 of the 10 cases (80%). CONCLUSIONS: This study shows that conservative treatment of blunt grades IV and V renal injury should be considered for patients with hemodynamic stability, no significant associated intra-abdominal organ injuries, devitalized segments less than 25% of renal parenchyma and ureteral opacification despite urinary extravasation on radiologic finding.

Background:
Telemetry is a wireless implanted device that measures biological signals in conscious animals and usually requires surgery for its removal when the study is finished. After removing the device, the animals are either used for other studies or euthanatized.Case presentation: Herein, we report the case of a living cynomolgus monkey (Macaca fascicularis) that was used for the entire experimental period, instead of euthanasia, after surgical removal of an implanted telemetry system.Radiography was used to determine the status of the implanted telemetry, following which, a repair surgery was performed for removing the system; clinical signs were used to preserve the life of the cynomolgus monkey. Postoperative clinical signs, food consumption, hematology, and serum biochemistry were examined during the 12-month observational period. No abnormal readings or conditions were observed in the subject after implant removal.
Conclusions
This study may be a useful case report for living cynomolgus monkeys in telemetry implantations used throughout the study period. We suggest minimizing the suffering and improving the welfare of these animals.

Purple urine bag syndrome (PUBS) is a rare phenomenon where the urinary catheter and bag turns purple following catheterization. The colors are formed from the substrate indoxyl sulfate (indican). PUBS is associated with urinary tract infections induced by the reaction of some species of bacteria with indoxyl sulfatase. We report here in a case of purple urine bag syndrome.

BACKGROUND: Percutaneous transluminal coronary angioplasty(PTCA) is one of the most widely used therapeutic procedures in the treatment of patients with coronary artery disease. However, acute closure and late restenosis remain a major limitation of PTCA despite extensive efforts to prevent. Coronary artery stents have been proposed as a treatment modality for acute closure and restenosis. We evaluated the initial success rate, complications, the restenosis rate, and the clinical outcomes after coronary artery stenting. METHODS: We implanted 56 stents(Palmaz-Schatz(PS) stent : 38 ; #3.0-14, #3.5-7, #4.0-17, Gianturco-Roubin(GR) stent : 18 ; #2.5-4, #3.0-10, #3.5-1, #4.0-3) in 51 patients(male : 40, mean age : 58+/-1 year). The clinical characteristics of the subjects were unstable angina in 26(51%), stable angina in 2, and myocardial infarction in 23(45%) patients(acute : 18). Follow-up angiography was done at a mean duration of 5.4 month(1-12) after coronary stenting for 34 lesions(61%) of 30 patients. RESULTS: 1) The indications of stenting(n=56) were De novo in 33(59%), bailout procedure in 15(27%), suboptimal result after PTCA in 6, and restenosis after PTCA in 2 stents. The location of lesions were LAD in 24, RCA in 27, and circumflex artery in 5 lesions. Angiographic morphologic characteristics were type B in 38(BI : 3, B2 : 35) and type C in 18 lesions. 2) The angiographic and clinical success rate was 96%(54/56) and 94%(52/56). There were no significant difference in stent modality, lesion site and morphology, and indication of stent. 3) Procedural complications were 1 acute closure which was recanalized by emergency coronary artery bypass graft(CABG), 1 death with subacute closure, 2 dissection, and 5 hemorrhages requiring transfusion. 4) The overall restenosis rate was 26%(9/34). The restenosis rate was reduced significantly in PS stent[PS : 9%(2/22) vs GR : 58%(7/12), P < 0.05], > or =3.5mm of stent size[> or =3.5mm : 6%(1/18) vs 3.5mm : 50%(8/16), p < 0305], and high pressure ballooning group(poststenting adjunct balloon dilation pressure > 12atm) [High pressure(+) : 7%(1/14) vs High pressure(-) : 40%(8/20), p<0.05]. 5) The restenosis sites were managed with re-PTCA in 4, elective CABG in 1, and medical follow-up in 4 patients. CONCLUSION: Coronary stenting is an effective and safe procedure for the management of coronary artery disease. The PS stent and GR stent are considered as a safe means for bail-out, and the PS stent can reduces the restenosis rate especially.

BACKGROUND: The endothelium is an important regulator of vascular tone via release of relaxing and constricting substances. The regulatory effect of the endothelium has been shown to be impaired in atherosclerotic arteries in human and animal models of hypertension. But there are some debates on extent and developing time of endothelium dysfunction in patients with hypertension, and the determining factors for endothelium dysfunction also were not defined. The objects of this study are to determine whether endothelial function is impaired in coronary and peripheral arteries, and to investigate the predicting factors for endothelial dysfunction in patients with essential hypertension. METHODS: The study patients comprised 14 patients with essential hypertension(M : 7, Mean age : 50+/-2 year) and 6 normal control (M :2, Mean age : 45+/-4 year). We assessed the vasomotor response to acetylcholine and nitroglycerin by change of arterial diameter during the infusion of acetylcholine, from 10(-9M) to 10(-6M) in coronary artery and 7.5, 15, and 25ug/min in left superficial femoral artery, and on intracoronary injection of 200ug nitroglycerin after acetylcholine infusion. RESULTS: 1) There were no significant differences in sex, age, body mass index and ventricular mass index, except systolic(174+/-5 vs 118+/-7mmHg, p<0.001) and distolic blood pressure(106+/-5 vs 75+/-5mmHg,p<0.001) between patients with hypertension and normal control. 2) There were no significant differences in laboratory date of total cholesterol, HDL-cho-lesterol, lipoprotein(a), microaluminuria and von-Willebrand Factor but Fibrinogen level was raised significantly in patients with hypertension than normal control(299+/-26 vs 192+/-23ng/dl, p=0.04). 3) The vasoconstrictor response to acetylcholine, 10-8 to 10-6 M concentration, at proximal, mid, and distal left anterior descending coronary artery were increased significantly in hypertensive patients than normal control(p<0.05). At rest superficial femoral artery, the vasodilator response to acetylcholine, only 25ug/min, was decreased in patients with hypertension(p<0.05). There was no signficant difference in the vasodilator response to nitroglycerin at coronary artery between two groups but in superficial femoral artery, the vasodilator response to nitroglycerin was decreased significantly in hypertensive patients(p<0.05). CONCLUSIONS: The results of this study suggest that endothelium dependent vascular relaxation is impaired in both coronary and superificial femoral artery and it remained to be investigated the predicting factors for endothelial dysfunction in patients with essential hypertension.

A 35-year-old woman suffered from elementary visual symptom that was confirmed as nonconvulsive simple partial status epilepticus arising from the right occipital lobe. 99mTc-ECD SPECT and 18F-FDG PET were done during the ictal and interictal phase, respectively, which were documented by EEG. Subtraction images of SPECT and PET were overlayed on the MRI by SISCOM to compare the area of metabolic change with that of perfusion change. There was no definite mismatch between the hypermetabolic area and the hyperperfusion area during nonconvulsive status epilepticus.
