Tracheal agenesis is an extremely rare and typically lethal congenital disorder. Approximately 150 cases have been described since 1900, and very few cases of survival have been reported. We describe tracheal reconstruction with external esophageal stenting in a patient with Floyd's type II tracheal agenesis. Neither long-term survival nor survival without mechanical ventilation for even a single day has previously been reported in patients with Floyd's type II tracheal agenesis. The infant in the present case survived for almost a year and breathed without a ventilator for approximately 50 days after airway reconstruction using external supportive stents.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature.

PURPOSE: Soft tissue reconstruction is essential for recovery of finger function and aesthetics in any traumatic defect. The authors applied a reverse homodigital artery island flap for soft tissue defect on distal part of digits. The aim of this study is to evaluate the efficacy of the procedure. MATERIALS AND METHODS: Seven cases of soft tissue defects of finger tip were included in this study. There were six male and one female, mean age was 43 years and mean follow-up period was 38 months. The length of flaps ranged from 2.0 to 2.5 cm and width ranged from 1.0 to 2.0 cm. Flap survival, postoperative complications were evaluated. RESULTS: All flaps survived without loss. Donor sites were repaired with primary closure in five cases and skin graft in two cases. None of the patients showed significant complications and their average finger motion was 255degrees in total active motion at the last follow-up. CONCLUSION: The authors suggest that the reverse homodigital artery island flap could be a versatile treatment option for the soft tissue defect on distal part of digits.

BACKGROUND: Right ventricular apical (RVA) pacing induces left ventricular (LV) dyssynchrony, increases the risk of persistent atrial fibrillation in the long term. The aim was to investigate the effects of RVA pacing on left atrial (LA) function, which are unknown. METHODS: Echocardiographic evaluation including LV dyssynchrony based on conventional Doppler, tissue Doppler imaging and speckle tracking strain echocardiography was done before and after (12 months) single-chamber ventricular pacemaker implantation in 40 patients with sick sinus syndrome. Patients were divided to 2 groups, according to the RVA pacing frequency (group I had higher pacing rate of more than 50% and group II, less than 50%). RESULTS: There was no significant difference in LV ejection fraction, however, mean global LV strain, myocardial performance index, and parameters of LV dyssynchrony had shown significant changes after 12 months of RVA pacing. There were also significant increase in the LA volume index and the reduction of peak systolic LA strain and strain rate (SR), peak early and late diastolic SR after RVA pacing. Moreover, there was significant deterioration of LV dyssynchrony and both LA and LV longitudinal function in even group II. LA functional deterioration and LA volume was significantly correlated with the frequency of RVA pacing. CONCLUSION: LV dyssynchrony, induced by RVA pacing, significantly impaired active LA contraction and passive stretching, and these findings were shown in the patients with even less than 50% of RVA pacing. Impairment of LA strain/SR was significantly correlated with the frequency of RVA pacing.

Blastomyces dermatitidis is a dimorphic fungus that causes the systemic pyogranulomatous disease known as blastomycosis. Blastomycosis most often involves the lungs, skin, and may involve nearly every organ in the body. It is difficult, however, to diagnose blastomycosis in the early stage of pulmonary disease because clinical manifestations are varied from subclinical infection to acute respiratory distress syndrome. Since blastomycosis is often accompanied by granulomatous inflammation in histopathologic findings, differentiation from other etiologic diseases is important. We report a case of a 45-year-old male with pulmonary blastomycosis who had been misdiagnosed with tuberculosis for 3 months.

BACKGROUND AND OBJECTIVES: In the era of stents, lesion length remains an important predictor of restenosis. Drug-eluting stents (DESs) have significantly reduced in-stent restenosis (ISR), but results in long lesions are still lacking. Therefore, we investigated the impact of DESs on clinical outcomes in patients with diffuse coronary lesions. SUBJECTS AND METHODS: Between January 2004 and January 2005, 80 patients (94 lesions) with lesions >20 mm in length were treated with one or more DESs and underwent follow-up coronary angiography. The patients were divided into three groups: Group 1 was composed of those with lesions 21 to 35 mm in length, Group 2 was composed of those with lesions 36 to 50 mm in length, and Group 3 was composed of those with lesions > or =51 mm in length. RESULTS: The mean clinical follow-up duration was 9 months. On the 6-month follow-up angiogram, 6.4% of the lesions had binary ISR (5.0% in group 1, 8.7% in group 2, and 9.1% in group 3). The percent diameter stenosis was 6.0+/-18.15% in Group 1, 12.61+/-21.99% in Group 2, and 19.81+/-31.26% in Group 3(p< 0.05). Late lumen loss was 0.17+/-0.50 mm in Group 1, 0.39+/-0.66 mm in Group 2, and 0.59+/-0.93 mm in Group 3 (p<0.05). Lesion length was associated with an increase in percent diameter stenosis and late lumen loss (of 6.9% and 0.21 mm per 15 mm). CONCLUSION: DES implantation is considered safe and effective in the treatment of diffuse lesions. However, lesion length may be associated with an increase in percent diameter stenosis and late lumen loss at 6-month follow-up.

BACKGROUND: There are several echocardiographic parameters, such as early transmitral velocity/tissue Doppler mitral annular early diastolic velocity(E/Ea) or deceleration time, reported to be reliable indices to estimate pulmonary capillary wedge pressure(PCWP). Recently, B-type natriuretic peptide(BNP) level is also reported to increase in accordance with increased left ventricular filling pressure in systolic or diastolic heart failure. This study was performed to compare E/Ea and BNP for the ability to estimate PCWP. METHODS: Several echocardiographic Doppler parameters including especially E/Ea were obtained from transthoracic Doppler echocardiography. Simultaneously, serum BNP level and PCWP estimated by using Swan-Ganz catheter were obtained, respectively. RESULTS: E/Ea revealed a correlation of r=0.88 (p<0.001) with PCWP compared with r=0.45 (p<0.001) between BNP and PCWP. E/Ea > or =11 was the optimal cutoff to predict PCWP > or =15 mmHg (sensitivity, 94%; specificity, 90%), whereas the optimal BNP cutoff was > or =250 pg/mL (sensitivity, 52%; specificity, 74%). CONCLUSION: Mitral E/Ea has a better correlation with PCWP than BNP. Mitral E/Ea appears more sensitive and specific than BNP for PCWP > or =15 mmHg in cardiac patients.

BACKGROUND: Cardiac troponin I (cTnI) is most recently described and has nearly absolute myocardial tissue specificity, as well as high sensitivity. But an increased value for cTnI that indicates myocardial injury is not always synonym of myocardial infarction or ischemia due to coronary artery disease. METHODS: Retrospective follow-up study for whom underwent coronary angiography for suspected coronary artery disease was done if they had an elevated cTnI value and angiographically normal or minimal disease. RESULTS: 33 patients were qualified. Cut-off value for elevated cTnI was 0.06 ng/mL. Increased cTnI values were attributed to severe congestive heart failure in 7 patients, variant angina in 7 patients, myocarditis in 5 patients, pericarditis in 1 patient, severe myocardial bridge in 1 patient, rhabdomyolysis in 1 patient and cerebral infarction in 1 patient. Tachycardia was precipitating cause in 4 patients (sinus tachycardia, paroxysmal supraventricular tachycardia, paroxysmal atrial fibrillation and sustained ventricular tachycardia for each), two of whom had hemodynamic compromise. 2 of 33 patients had no identifiable cause for a rise in cTnI value. There was no acute myocardial infarction at 42+/-34 weeks follow-up. CONCLUSIONS: Although cTnI is a sensitive and specific marker of myocardial injury, an elevation of cTnI value may have a cause other than myocardial infarction or ischemia and may occur without significant angiographic coronary artery disease.

STUDY DESIGN: The comparison was based on the radiographc and clinically differences of 96 vertebroplasty cases. PURPOSE: This study evaluated the clinical and radiological results of performing percutaneous vertebroplasty for acute or subacute osteoporotic vertebral compression fracture (group A) and for posttraumatic vertebral collapse (Kummell's disease) (group B). SUMMARY OF LITERATURE REVIEW: Percutaneous vertebroplasty is a minimal invasive procedure for the treatment of a painful collapsed vertebral body MATERIALS AND METHODS: We experienced 67 cases of group A and 29 cases of group B, and we followed these patients for 2 years or more. We evaluated the clinical results by using the serial visual analogue scale (VAS) and the radiological results were evaluated by measuring the restoration of the anterior vertebral height and the change of the kyphotic angle. We also compared both groups for their bone mineral density (BMD) and new fracture rate. RESULTS: Statistically significant pain relief was obtained by both groups in the perioperative period. The average VAS change was 6.5 (from 8.7 preoperatively to 2.2 postoperatively) in group A, and 7.1 (from 9.1 preoperatively to 2.0 postoperatively) in group B on a 10 point pain scale. The anterior vertebral height increased an average of 4.9mm (16.5%), (from 16.8mm preoperatively to 21.7 mm postoperatively) in group A, and 6.5 mm (21%) (from 12.8 mm preoperatively to 19.3 mm postoperatively) in group B on the perioperative period. But the height was minimally decreased more that it was measured at the immediate postoperative period: 18.7 mm in group A, and 16.2 mm in group B on the last follow up. The kyphotic angle was restored an average of 5.2 degrees (from 32.4 degrees preoperatively to 27.2 degrees postoperatively) in group A, and 4.9 degrees (from 39.5 degrees preoperatively to 34.6 degrees postoperatively) in group B on the perioperative period. But the angle was increased more than that measured preoperatively: about 1.7 degree in group A and group B on the last follow up. There's no significant difference in the BMD between the groups. New fracture developed in 17.9% (12) of group A, and 20.7% (6) of group B. We did this procedure for 15 cases of new fracture, and then the VAS change was an average 5.0 immediately after the operation. CONCLUSIONS: Percutaneous vertebroplasty was an effective treatment method for both groups and there were no statistically significant differences in the clinical and radiological results. Care must be taken due to the relatively high rate of new fracture and this can be resolved by repeat vertebroplasty
