Nontuberculous mycobacterial infections are a rare, but clinically important cause of infections in continuous ambulatory peritoneal dialysis (CAPD) patients. This is typically suspected when a patient does not respond to treatment with the usual antibiotics. We describe here a case of Mycobacterium abscessus exit site infection with abdominal wall abscess formation that was associated with CAPD, which required peritoneal catheter removal, surgical debridement of the abscess and long term antibiotic therapy.

Abstract PDF: Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects the medium-sized muscular arteries, with occasional involvement of the small muscular arteries. As with other vasculitides, PAN can affect any organ system, including the cardiovascular, gastrointestinal and central nervous systems. The prognosis for patients with untreated PAN is relatively poor, with five-year survival rates of approximately 13 percent. The outcome has improved with proper therapy to approximately 80 percent survival at five years. We report here on a case of a 46 year old man with polyarteritis nodosa and who suffered from pulmonary tuberculosis.

Abstract PDF: Primary cardiac tumors are very uncommon. Seventy five percent of them are benign tumors and these are mostly myxomas. The malignant cardiac tumors, the majority of which are undifferentiated sarcomas, comprise up to 25% of all cardiac tumors. A primary malignant sarcoma of the myocardium is exceedingly rare. Thus, there have been very few such cases reported in the literature. We present here a case of a 15 year old man who had complaints of orthopnea and increasing exercise intolerance over a one month period. Transthoracic echocardiography demonstrated a well demarcated huge mass with left ventricular inflow obstruction on the posterior wall of the left atrium. The patient's symptoms were relieved by surgery. The histological diagnosis was an unclassified spindle cell sarcoma.

Abstract PDF: BACKGROUND
The occurrence of atrial fibrillation after ablation of atrial flutter is clinically important. We investigated variables predicting this evolution in ablated patients without a previous atrial fibrillation history. MATERIALS AND METHODS: Thirty-six patients (Male=28) who were diagnosed as atrial flutter without previous atrial fibrillation history were enrolled in this study. Group 1 (n=11) was defined as those who developed atrial fibrillation after atrial flutter ablation during 1 year follow-up. Group 2 (n=25) was defined as those who has not occurred atrial fibrillation during same follow-up term. Echocardiogram was performed to all patients. We measured left atrial size, left ventricle end diastolic and systolic dimension, ejection fraction and left atrial volume index before and after ablation of atrial flutter. The differences of each variables were compared and analyzed between two groups. RESULTS: The preablation left ventricular ejection fraction (preLVEF) and postablation left ventricular ejection fraction (postLVEF) are 54+/-14%, 56+/-13% in group 1 and 47+/-16%, 52+/-13% in group 2. The differences between each two groups are statistically insignificant (2.2+/-1.5 in group 1 vs 5.4+/-9.8 in group 2, p=0.53). The preablation left atrial size (preLA) and postablation left atrial size (postLA) are 40+/-4 mm, 41+/-4 mm in group1 and 44+/-8 mm, 41+/-4 mm in group 2. The atrial sizes of both groups were increased but, the differences of left atrial size between two groups before and after flutter ablation were statistically insignificant (0.6+/-0.9mm in group 1 vs -3.8+/-7.4 mm in group 2, p=0.149). The left atrial volume index before flutter ablation was significantly reduced in group 1 than group 2 (32+/-10 mm3/m2, 35+/-10 mm3/m2 in group 1 and 32+/-10 mm3/m2, 29+/-8 mm3/m2 in group 2, p<0.05). CONCLUSION: The difference between left atrial volume index before and after atrial flutter ablation is the robust predictor of occurrence of atrial fibrillation after atrial flutter ablation without previous atrial fibrillation.
