Corrected transposition of the great arteries is usually characterized by inverted ventricles and transposition of the great arteries. This combination without cardiac anormalies results in normal arterial oxigen content, hence the term corrected. Unfortunately, the condition rarely exists without other major cardiac anormalies. The authors report a case of situs inversus that was associated with corrected TGA, VSD, PS and ASD. The girl was admitted for evaluation of systolic ejection murmur on the both lower sternal border. Doppler echocardiography and cardiac angiography showed the diagnosis and so valvulotomy and closure operation of VSD and ASD was done.

Patients with acromegaly have a reduced life expectancy rnainly due to cardiovascular, respiratory or cerebrovascular diseas-. Malignancy also seems to occur with greater than the expected incidence. In particular, the published retrospective or prospective studies have suggested a strong association of colonic neoplasia with acromegaly. But, there were a few reports of thyroid cancer in acrornegaly. We report a case of thyroid papillary cancer derived from diffuse goiter in acromegaly, sugge- sting the possible carcinogenic role of growth hormone.

Pneumoperitoneum, Pneumomediastinum, subcutaneous emphysema and a pneumothorax are some of the mechanical complications of bronchial asthma. The incidence of pneumoperitoneum during an attack of acute asthma is rare. The pathogenesis is free gas track from the overdistended alveoli, through the bronchovascular sheaths to the mediastinum. If the high pressure is maintained, air can escape retroperitoneally into the abdomen and burst into the peritoneal cavity. A 43-year-old woman was admitted due to a severe asthma attack. She was required endotracheal intubation and AMBU(air mask bag unit) ventilation. Immediately after these procedures, pneumoperiotneum, pneumomediastinum, and subcutaneous emphysema daveloped. She was treated with mechanical ventilation and medical therapy. The pneumoperitoneum was resolved after 27 days. Here, we report this case with the review of the relevant literature.

The objectives of this investigation were to evaluate biomechanical factors in the atherosclerotic process using human in vivo hemodynamic parameters and computed numerical simulation qualitatively and quantitatively. The three-dimensional spatial patterns of steady and pulsatile flows in the left coronary artery were simulated, using a finite volume method. Coronary angiogram and Doppler ultrasound measurement of the proximal left coronary flow velocity were performed in humans. Inlet wave velocity distribution obtained from in vivo data of the intravascular Doppler study allowed for input of in vitro numerical simulation. Hemodynamic variables, such as flow velocity, pressure and shear stress of the left anterior descending coronary bifurcation site were calculated. We found that there were spatial fluctuation of flow-velocity and recirculation areas at the curved outer wall of the left anterior descending coronary artery, which were due to the differences of flow-velocity and shear stress, especially during the declaration phase of pulsatile flow. This study suggests that rheologic properties may be a part of the atherogenic process in the coronary bifurcated and curved areas.

OBJECTIVES: To evaluate the surgical outcomes of endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stenting in patients with distal or common canalicular obstructions. METHODS: The medical records of 29 patients (31 eyes) from January 2001 to December 2009 who underwent endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone tube insertion for the treatment of distal or common canalicular obstructions were retrospectively reviewed. The level of obstruction was confirmed by intraoperative probing. The outcome of the surgery was categorized as a complete success, partial success, or failure according to the functional and anatomic patency. RESULTS: The average age of the patients was 52 years. The duration of silicone intubation ranged from 4 to 11 months with an average of 5.7+/-1.6 months. The follow-up period after stent removal ranged from 4 to 15 months with an average of 8.2+/-3.3 months. Complete success was achieved in 25 out of 31 eyes (80.6%), partial success in 4 out of 31 eyes (12.9%), and failure in 2 out of 31 eyes (6.5%). CONCLUSION: Endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stent intubation may be safe and considered as an initial treatment of patients with distal or common canalicular obstructions.

BACKGROUND: H. pylori-associated gastrointestinal diseases have been widely recognized. The aim of this study was to investigate the seropositivity of H. pylori in health check-up subjects and to find out the relating factors. METHODS: From November 2004 through June 2005, total 7,676 health check-up subjects (age > or =20) responded to the self administered questionnaires. The prevalence of H. pylori was assessed by measuring anti-H. pylori IgG antibodies. RESULTS: The overall seropositivity was 56.7% in 7,676 and 1,137 (14.8%) has been found to have history of H. pylori eradication therapy. The seropositivity rate of H. pylori was 61.3% (2,653) in 4,328 subjects without history of H. pylori eradication and current gastrointestinal symptoms. Seroprevalence of H. pylori was significantly lower in 20~29 years old, female, high income and subjects from Seoul respectively. CONCLUSIONS: The seropositivity of H. pylori in 2004~2005 is found to be 61.3% in subjects without history of H. pylori eradication and current gastrointestinal symptoms. This seems to be lower than 66.9%, the seroprevalence rate in asymptomatic Korean population in the age of > or =16 years in 1998. This decrease might be caused by improvement of socioeconomic status.

Rhabdomyolysis is caused by injury to skeletal muscle and it involves leakage of intracellular contents into the plasma. Rhabdomyolysis is an extremely rare manifestation of dermatomyositis. Dermatomyositis is a rare idiopathic inflammatory myopathy that is characterized by chronic inflammation of skeletal muscles and skin, resulting in muscle weakness. A 20 year old Korean male soldier presented with acute muscle pain, weakness and skin rashes over the face, neck and anterior chest. He received military training with carrying a radio set one week previouslyago. The patient was treated for rhabdomyolysis. However, the patient's symptoms did not improve. Muscle biopsy results suggested the diagnosis of rhabdomyolysis. Nevertheless, the features of skin and muscle inflammation raised the possibility of dermatomyositis. High dose steroid treatment was started, and then the symptoms and signs of muscle inflammation were improved. Rhabdomyolysis as the presenting sign of dermatomyositis has not been reported in Korea. Thus, we report on this case with a literature review.

The objective of the present study was to evaluate the hemodynamic characteristics of an atherosclerosis-prone coronary artery compared to the aorta. We describe three- dimensional spatial patterns of wall shear stress (WSS) according to the impedance phase angle in pulsatile coronary and aorta models using in vivo hemodynamic parameters and computed numerical simulations both qualitatively and quantitatively. Angiography of coronary arteries and aortas were done to obtain a standard model of vascular geometry. Simultaneously to the physiologic studies, flow-velocity and pressure profiles from in vivo data of the intravascular Doppler and pressure wire studies allowed us to include in vitro numerical simulations. Hemodynamic variables, such as flow-velocity, pressure and WSS in the coronary and aorta models were calculated taking into account the effects of vessel compliance and phase angle between pressure and flow waveforms. We found that there were spatial fluctuations of WSS and in the recirculation areas at the curved outer wall surface of the coronary artery. The mean WSS of the calculated negative phase angle increased in the coronary artery model over that in the aorta model and the phase angle effect was most prominent on the calculated amplitude of WSS of the coronary artery. This study suggests that the rheologic property of coronary circulation, such as the fluctuation of WSS/WSR induces several hemodynamic characteristics. A separation of flow-velocity, a difference in phase between pressure conductance and blood flow and prominent temporal and/or spatial oscillatory fluctuations of the shear forces as a function of pulsatile flow might be important factors in atherogenesis and progression of atherosclerosis.

Inflammation appears to have a major role in the development of atherosclerosis. Cyclooxygenase-2 (COX-2) is involved in the inflammatory response via the generation of prostanoids that, in turn, are involved in the production of matrix metalloproteinases (MMPs). This study aimed to investigate atherosclerosis in human aortas for in situ tissue distribution of COX-2, MMPs including MMP-9 and membrane type 1 MMP (MT1-MMP), and tissue inhibitor of metalloproteinase-2 (TIMP-2). Immunohistochemical studies were performed on atherosclerotic lesions of aortas from patients with aortic aneurysms (n = 4) and dissections (n = 3) by using antibodies to COX-2, MMP-9, MT1-MMP, and TIMP-2. Control tissues were obtained from traumatically dissected aortas (n = 2). All specimens from diseased aortas had atherosclerotic lesions ranging from fatty streak to atheromatous plaques. In control, there was no expression of COX-2, MMP-9, and MT1-MMP in all aortic layers. Immunoreactivity for COX-2 was predominantly noted in macrophages and smooth muscle cells (SMCs) of the intima including atherosclerotic plaque itself and the medial layer of the plaque base, as well as in SMCs and endothelial lining of the vasa vasorum in the adventitia. Immunoreactivity for MMP-9 and MT1-MMP was found in the same distribution as that of COX-2. Additionally, the expression of TIMP-2 increased in relation to MMP-9 expression. This study demonstrates that COX-2 is coexpressed with MMP-9 and MT1-MMP, not only by macrophages and SMCs in atherosclerotic lesions, but also in endothelial lining of the vasa vasorum of human aortas. Thus, vascular inflammatory reactions may influence extracellular matrix remodeling by coactivation of MMPs in the development of atherosclerosis and, in turn, the progression of disease.

Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.
