Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, proximal portion of its major branches, and causes narrowing, occlusion, or aneurysmal dilatation of vessel. Authors report 2 cases of Takayasa's arteritis with brief review of the literature.

Aortic valve replacement with aortic allograft has been considered a treatment of choice for aortic valve disease secondary to bacterial endocarditis because of its good homodynamic performance and higher resistance to infection. The aortic root replacement technique might be superior to the subcoronary allograft implantation technique with regard to aortic regurgitation. A 46 yea,rs old male patient had acute aortic regurgitation with progressing heart failure secondary to acute bacterial endocarditis. The patient underwent emergent aortic root replacement using 20 mm aortic allograft. At operation, right coronary cusp perforation and heavy calcification of commissure between right and left coronary cusp were observed. The patient recovered well and postoperative echocardiography demonstrated no aortic regurgitation. Inflammatory signs were subsided after 8 weeks of antibiotics therapy. Medically uncontrolled acute bacterial endocarditis was treated successfully by aortic root replacement using aortic homograft.

Microscopic Polyangiitis(MPA) belongs to a spectrum of systemic vasculits, and particularly antineutrophil cytoplasmic autoantibodies(ANCA)-associated small-vessel vasculitis which is characterized by involvement of the lung and kidney. The diagnosis of MPA is often difficult to make, and delayed because of the variability of the clinical presentation. Renal biopsies have a very important diagnostic and prognostic value in MPA. We experienced a case of microscopic polyangiits which was confirmed by renal biopsy and positive serum perinuclear ANCA, associated with alveolar hemorrhage and gastrointestinal bleeding. We began methylprednisolone pulse therapy, combined with a low dose of cyclophosphamide and plasmapheresis therapy. ACE inhibitor and Ca channel blocker were used when proteinuria and hypertention developed. On admission, the patient's lab findings showed BUN l17 mg/dL, Cr 2.3 mg/dL, while on the 60th hospital day BUN/Cr values fell to 20.8 mg/dL / 1.6 mg/dL and though proteinuria persisted, the patient's condition was tolerable and is currently under observation on an out-patient basis. The last lab values were BUN 26 mg/dL / Cr 1.6 mg/dL. (J. Korean Soc Pediatr Nephrol 2001 ; 5 : 213-18)

It is now widely accepted that the complete arterial coronary revascularization has better short and long term results compared to coronary bypass surgery using arterial graft mixed with vein graft mainly due to its superior patency rate. However, sometimes the internal thoracic artery and other conventionally used grafts might be unavailable or it may require caution in using bilateral internal thoracic artery especially in diabetic patient because of the possible risk of the mediastinitis or other associated morbidities. Moreover, there could also be a shortage for arterial graft in case of coronary reoperation. We report our first three cases using thoracodorsal artery(TDA) as an alternative graft in complete arterial coronary revascularization.

Background: Cognitive deficit by hypoxia and/or hypercapnia is one of neuropsychological impairments frequently observed in patients with chronic obstructive pulmonary disease (COPD). The degree of cognitive deficit is variable among patients with similar level of hypoxia and/or hypercapnia, although a cause of this individual difference is well not known. COPD can be divided into two characteristic clinical entities including predominant emphysema and predominant bronchitis. This study was designed to evaluate the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD. Method: Sixteen patients with COPD (9 emphysema-dominant and 7 bronchitis-dominant) participated in this study. On admission arterial blood gas analysis and trail-making B (TMB) test for the evaluation of cognitive function were done in all patients. Mean TMB scores and the correlations between TMB scores and arterial blood gases were compared between two clinical groups. Results: 1) Mean TMB scores and arterial blood gases between two clinical groups were not different. 2) There was a tendency to be higher TMB score in hypoxemia, acidemia, and hypercapnia. However these findings were not statistically significant. 3) In emphysema-dominant group, $PaCO_2$ was mostly well correlated with TMB score (r=0.693). 4) In bronchitis-dominant group, arterial pH was mostly well correlated with TMB score (r=-0.526). Conclusion: Our data suggest that the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD may be dependent on their clinical entities, and arterial blood gases mostly well correlated with cognitive function that may be different according to their clinical entities.

Acute mediastinitis and subsequent graft infection following aorta surgery poses a difficult problem, as infected synthetic material must be completely removed for resolution of infection. Here we report a case of successful management of acute mediastinitis following hemiarch replacement for acute aortic dissection with omental flap transfer leaving infected graft in situ.
