ABSTRACT
BACKGROUND: Bronchial anthracofibrosis, which is defined as bronchial narrowing with black pigmentation of the overlying bronchial mucosa, is frequently associated with tuberculosis. The aim of this study was to examine the relationship between bronchial anthrocofibrosis and to identify the clinical and radiological characteristics of non-tuberculous bronchial anthracofibrosis. METHODS: All patients who showed bronchial anthracofibrosis in more than one segment on a bronchoscopic examination from January 2003 to July 2006 at Kangnam St. Mary's hospital were enrolled in this study. The underlying diseases, baseline clinical characteristics, characteristic findings on a computed tomogram (CT) of the chest, pathologic findings of the bronchial mucosa, and the clinical response to steroid therapy were analyzed retrospectively. RESULTS: A total 54 patients (19 males, 35 females) were enrolled with a mean age of 75 years. The most common presenting symptoms were cough, sputum and dyspnea. The predominant X-ray findings were peribronchial soft tissue attenuation with or without calcification, mediastinal lymphadenopathy with or without calcification and atelectasis. Fourteen non-tuberculous anthracofibrosis patients were treated with steroid. Nine patients were improved clinically, and 6 patients were improved radiologically. CONCLUSION: Bronchial anthracofibrosis is frequently associated with various pulmonary diseases not only tuberculosis but also COPD pneumonia etc.

The follow-up of patients after performing potentially curative resection for colon cancer is important, yet the ideal surveillance strategy has not been defined. Periodic clinical examinations, laboratory tests, radiographic imaging, colonoscopy and carcinoembryonic antigen (CEA) testing have been utilized for surveillance, and the serial CEA measurement is the most cost-effective test for identifying the recurrence of disease. However, this test also indicates the development of secondary gastrointestinal malignancy such as gastric cancer or duodenal cancer. We report here on a case of metachronous duodenal adenocarcinoma that was revealed by the serial measurement of the serum CEA after we performed curative resection for colon cancer.

BACKGROUND: Radiofrequency catheter ablation (RFCA) becomes an useful treatment for idiopathic ventricular tachycardia, especially right ventricular outflow tract ventricular tachycardia (RVOT VT) typically originates from "superior septal" aspect of right ventricular outflow tract. However, some of the right ventricular outflow tachycardias remain resistant despite repeated attempts of RFCA. This study was focused to search the electrocardiographic characteristics suggesting procedural success of radiofrequency ablation in RVOT VT and ventricular tachycardia that can not be ablated by conventional approach confined to right ventricular outflow tract even though to show similar electrocardiographic morphology. METHODS: The study subjects were 25 patients who underwent RFCA with the diagnosis of RVOT VT. We classified the study subjects into 2 groups and in group 1 (N=17, Age 47.5 +/- 16.8) in those successful RFCA was possible in RVOT. In group 2 (N=8, Age 54.8 +/- 8.0), the removal of VT was not possible with the RFCA confined in RVOT. We analyzed the morphologic characteristics of QRS complex of VT or ventricular premature beats in right precordial leads; V(1-3). The QRS and R wave duration, height of R wave, depth of S wave, R/S ratio and R wave duration index were measured. RESULTS: There was no difference of age and sex between group 1 and 2 (Group 1: N=17, Male 29.4%, Age 49.5 +/- 16.8 vs Group 2: N=8, Age 54.8 +/- 8.0, Male 37.5%). The maximal QRS duration in V(1-3) was 144.2 +/- 23.6 ms in group 1 and 136.3 +/- 25.1 ms in group 2. The R wave duration and R wave duration index were not different either between group 1 and 2. However, the R wave duration of lead V 3 in group 2 was 97.0 +/- 34.4 ms and significantly longer than 65.0 +/- 26.0 msec in Group 1 (p=0.04). R wave duration index also showed significant difference between two groups: 72.0 +/- 23.5% of group 2 vs 45.4 +/- 17.8% of group 1. In comparison of R wave height and depth of S wave in V(1-3) between two groups, the R/S ratio of lead V3 in group 2 showed the ratio of 343.4 +/- 227.7% which was significantly larger than 97.4 +/- 92.2% in group 1. CONCLUSION: For the practice of RFCA for RVOT VT, morphologic characterstics of VT or VPC showing wide R wave and high R/S wave ratio in precordial leads, especially in V3 could be an useful electrocardiographic indicator to suspect the unusual focus of idiopathic VT showing inferior axis and LBBB pattern.

The reVersible posterior leukoencephalopathy syndrome (RPLS) describes a syndrome of headaches, confusion, seizures, and visual disturbances associated with transient, predominantly posterior cerebral lesions revealed by neuroimaging. RPLS has been associated clinically with hypertension, immunosuppression, and known triggers include acute renal failure, eclampsia, cyclosporine, and lupus. We report a 45-year-old male with chronic renal failure showed RPLS following hemodialysis and review literatures.

Unilateral adrenal hyperplasia (UAH) is a rare, surgically correctable subset of primary aldosteronism. It has similar clinical features to aldosterone-producing adenoma (APA), but different pathologic finding. We report a case of UAH in a 51-year-old Korean man. The patient had hypertension. Hypokalemia and suppressed plasma renin activity (PRA) with elevated plasma aldosterone concentration (PAC) was observed. The 1.5 cm-sized nodule in left adrenal gland was scanned by abdominal computed tomography (CT). The selective adrenal venous sampling for determinations of PAC showed an overfunctioning left adrenal gland, and laparoscopic left adrenalectomy was performed. Pathologically, 1.3 cm-sized nodular hyperplasia lesion was observed. Hypokalemia, hypertension, and endocrine data were corrected after surgery, and there was no sign of recurrence for eight months after surgery. Clinical features of UAH are also reviewed.
