A 68 year-old woman visited our hospital because of constipation and hematochezia. Colonoscopy revealed an invasive fungating mass with a narrowing of lumen and severe ulceration at the sigmoid colon. An abdominal/pelvic CT scan showed an irregular wall thickening with a 10cm long narrowing at the sigmoid colon, and a 2 cm long right adrenal mass. We did an anterior resection and adrenalectomy. The histology of the specimens of the resected sigmoid colon and adrenal gland was the same. Finally, we diagnosed this case as being an adrenal metastasis from an advanced sigmoid colon cancer. The patient has been well for a year since the adrenalectomy, and been treated by the oral chemotherapeutic agent: doxifluridine 600 mg, leucovorin 90 mg.

BACKGROUND: During and immediately after percutaneous transluminal coronary angioplasty(PTCA), reversible ischemic electrocardiographic change and/of left ventricular dysfunction are developed. But it is not investigated whether there are potential myocardial cell damages following PTCA or not, and the clinical Significance of myocardial cell damage following PTCA. Recently cardiac Troponin-T has been developed as a new myocardial specific marker, especially myocardial damage. The object of this study is to investigate whether potential Myocardial damage following PTCA was occurred and the utility of cardiac Tropoin-T for predicting the complications during and immediately after PTCA. METHODS: The study group comprised 12 patients(M/F;8/4mean age;60 +/- 4year,AMI in 6) undergoing PTCA, Samples for Troponin-T were obtained before, directly after, after 2 hours, 6 hours, and after 12 hours and was determined by enzyme immunoassay on an ES 300 analyzer(Boehringer Mannheim). Discrimination limit for myocardial cell damage is 0.1 ng/ml in normal baseline level but if the baseline level is elevated such as acute myocardial infarction or unstable angina, myocardial cell damage is defined with further increase of cardiac Troponin-T(>0.1 ng/ml) compare to baseline level. RESULTS: 1) The mean duration of total balloon inflation is 10.7 +/- 2(3-22) minutes and the mean duration of single maximal inflation is 3.9 +/- 0.6(1-8) minutes. There are no significant change in concentration of Troponin-T by inflation time. None of the patients showed electroca rdiographic evidence for myocardial infarction. 2) Troponin-T were increased in 2 patients with unstable angina(0.01 vs 0.11 ng/ml) which were developed major dissection including acute closure during PTCA, and 2 patients with acute myocardial infarction(2.37 vs 3.73 ng/ml) which didn't developed dcomplication. The increase of cardiac Troponin-T were observed in 2 of 10 patients with uncomplicated PTCA(20%). 3)The subacute complications were not developed. CONCLUSION: The cardiac Troponin-T were increased significantly in two AMI patients with uncomplicated PTCA(2/10,20%). The increase of cardiac Troponin-T following PTCA is associated with periprocedural complications but the prognostic significance to detect postprocedural complication did not define in this study because there were no subacute complications after PTCA and may be limited value due to time course of complication(usaully within 1 hour after PTCA) and relatively long analytic time.

Scleroderma renal crisis is defined as the new onset of accelerated arterial hypertension and/or rapidly progressive oliguric renal failure. The pathogenesis is not well understood but there is increasing evidence that renin- angiotensin system is involved. We report an one female patient with diffuse scleroderma and renal crisis. Initial treatment with ACE inhibitor was not effective in controlling blood pressure until the temporal initiation of hemodialysis. Predialysis serum creatinine level was 8.4 mg/dL, but after initiation of hemodialysis, adequate control of blood pressure was achieved with ACE inhibitor alone. This case illustrated many features of the syndrome of scleroderma renal crisis and supported the early use of captopril and emergency hemodialysis if indicated.

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.

BACKGROUND: Demodicosis is a parasitic skin disease caused by Demodex mites, and the determination of mite density per square centimeter is important to diagnose demodicosis. Standardized skin surface biopsy (SSSB) and direct microscopic examination (DME) are commonly used to determine Demodex mites density (Dd). However, no study has previously compared these two methods with respect to clinical types and distribution patterns of demodicosis. OBJECTIVE: The aim of this study was to compare the value of SSSB and DME findings in reference to the clinical types and distribution patterns of demodicosis. METHODS: The medical records of 35 patients diagnosed with demodicosis between December 2011 and June 2015 were retrospectively reviewed. Demodicosis was classified according to four clinical types (pityriasis folliculorum, rosacea type, acne type, and perioral type) and three distribution patterns (diffuse pattern, U-zone pattern, and T-zone pattern). Two samples, one for SSSB and one for DME, were obtained from a lesion of each patient. RESULTS: In all patients, mean Dd and the proportion with a high Dd (>5D/cm²) by DME (14.5±3.3, 80.0%, respectively) were higher than by SSSB (5.5±1.3, 37.1%, respectively; p<0.01, p=0.02, respectively). In terms of clinical types, for rosacea type, mean Dd and proportion with a high Dd by DME (12.4±3.5, 84.6%, respectively) were significantly greater than those determined by SSSB (3.6±1.2, 23.1%; p=0.04, p=0.04, respectively). In terms of distribution pattern, for the diffuse pattern, mean Dd and the proportion with a high Dd by DME (17.5±3.7, 100%, respectively) were significantly higher than those determined by SSSB (6.0±2.7, 26.7%; p<0.01, p<0.01, respectively). CONCLUSION: The results of our study revealed that DME is a more sensitive method for detecting Demodex than SSSB, especially in patients with diffuse pattern and suspected rosacea type. Further research is needed to confirm this finding.

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.

BACKGROUND: The information on nasal transport and the metabolism of peptides have been obtained from pharmacokinetic investigations in experimental animals. However, there are no transport and metabolic studies of human nasal epithelial cells. In this study, the permeability characteristics and the metabolic properties of in vitro human nasal cell monolayers were investigated. Material and METHODS: Normal human inferior nasal conchal tissue samples were obtained from patients undergoing endoscopic nasal cavitary surgery. The specimens were cultured in a transwell using an air-liquid interface (ALI) culture, and the transepithelial electrical resistance (TEER) value of the blank filter and confluent cell monolayers were measured. To determine the % leakage of mannitol, 4µmol 14C-labelled mannitol was added and the % leakage was measured every 10 minute for 1 hour. RESULT: Human nasal epithelial cells in the primary culture grew to a confluent monolayer within 7 days and expressed microvilli. The tight junction between the cells was confirmed by transmission electron microscopy. The TEER value of the blank filter, fifth day and seventh day reached 108.5 ohm.cm2, 141 ohm.cm2 and 177.5 ohm.cm2, respectively. Transcellular % leakage of the 14C-mannitol at 10, 20, 30, 40, 50 and 60 minutes was 35.67±5.43, 34.42±5.60, 32.75±5.71, 31.76±4.22, 30.96±3.49 and 29.60±3.68 %, respectively. CONCLUSION: The human nasal epithelial monolayer using ALI using techniques is suitable for a transcellular permeability study. The data suggests that human nasal epithelial cells in as ALI culture technique shows some promise for a nasal transport and metabolism study.
