Successful Radiofrequency Catheter Ablation of Epicardial Left Ventricular Outflow Tract Tachycardia from the Anterior Interventricular Coronary Vein

JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 12 2005
YASUHIRO HIRASAWA M.D.
We report a case of idiopathic left ventricular outflow tract (LVOT) tachycardia that was eliminated by a radiofrequency application from the anterior interventricular coronary vein (AIV). The ECG exhibited QRS complexes with an inferior axis and atypical left bundle branch block pattern with an early transition of the precordial R waves at V3. Several radiofrequency applications from the coronary cusps and endocardial LVOT were not effective. Radiofrequency applications in the AIV, where the activation preceded the onset of the QRS by 30 msec, successfully eliminated the tachycardia. The AIV may be an optional site for radiofrequency ablation of idiopathic epicardial LVOT tachycardia. [source]

Can early liver biopsies predict long-term outcome of the graft?

LIVER TRANSPLANTATION, Issue 1 2003
Lydia M. Petrovic MD
Background: Chronic rejection (CR) in liver allografts show a rapid onset and progressive course, leading to graft failure within the first year after transplantation. Most cases are preceded by episodes of acute cellular rejection (AR), but histological features predictive for the transition toward CR are not well documented. Method: We assessed the predictive value of centrilobular necrosis, central vein endothelialitis (CVE), central vein fibrosis, and lobular inflammation in the development of CR. One-week and one-month biopsy specimens of 12 patients with CR were compared with those of a control group consisting of 17 patients, who experienced AR without developing CR. The progress of the histological changes was further evaluated in follow-up biopsy specimens of the CR group taken at 2 months and beyond 3 months after transplantation. Result: Centrilobular necrosis, CVE, central vein fibrosis, and lobular inflammation were common features in both groups at 1 week. At 1 month, the incidence declined in the control group. The CR group showed an increased incidence and persistence of these features in the follow-up specimens. The incidence and median grade of severity of CVE was significantly higher in the CR group (p=0.04, and P<0.001). The severity of portal and lobular inflammation was also more pronounced in the CR group (P+0.01 and 0.069). Conversely, in the control group the incidence of the lobular features decreased and the severity of CVE declined significantly (P=0.03). Conclusion: The shift from a predominantly portal-based process toward lobular graft damage represents the early transition of AR to CR, for which a modification of immunosuppression might be necessary to prevent graft loss.

Continued decline for ethnic minorities in the transition?

THE ECONOMICS OF TRANSITION, Issue 4 2003
Changes in ethnic earnings differentials in Bulgaria
Abstract Using three Bulgarian cross-sectional household surveys from 1986, 1993 and 1997, this essay shows that the mean log wage differential between ethnic Bulgarians and Turks increased from 0.1615 in 1986 to 0.2874 in 1993 and again to 0.4075 by 1997. Bulgarian gains over ethnic Turks in the early transition are related to both changes in the relative returns to skill and changes in the composition of demand for goods and services as the country moved toward a market economy. The Turks began the transition with fewer years of education than the Bulgarians, and began to close the education gap over this time. The Bulgarians, however, were more likely to have obtained more general secondary and university degrees than the ethnic Turks , degrees that, in contrast to technical or vocational degrees, are experiencing increased remuneration in the transition. With more of an asset that has become more valuable, the ethnic Bulgarians improved their relative position. [source]

Which mothers wean their babies prematurely from full breastfeeding?

ACTA PAEDIATRICA, Issue 8 2009
An Australian cohort study
Abstract Aim:, To identify the maternal and infant characteristics associated with an early transition from full breastfeeding to complementary or no breastfeeding during the first 2 months of life in a large, representative cohort of Australian infants. Method:, Multinomial logistic modelling was performed on data for infants with complete breastfeeding and sociodemographic data (N = 4679) including maternal age, education, smoking, employment, pregnancy and birth outcomes. Results:, Ninety-one percent of women initiated breastfeeding. Sixty-nine percent of infants were being fully breastfed at 1 month, and 59% were fully breastfed at 2 months. Maternal characteristics , age less than 25 years, smoking in pregnancy, early full-time postnatal employment and less educational attainment , were associated with early breastfeeding cessation. Infant factors , multiple birth, caesarean birth, infant or first birth , were associated with a transition to complementary breastfeeding in the first postnatal month. Conclusion:, Breastfeeding duration is substantially affected by breastfeeding outcomes in the first postpartum month. The first month is an important window for evidence-based interventions to improve rates of full breastfeeding in groups of women identified as at risk of early breastfeeding cessation. [source]
