Introduction: Differentiation between AVNRT and AVRT can be sometimes challenging. Apical right ventricular (RV) entrainment can help in differentiation, however it has some fallacies. We thought to compare the accuracy of basal RV entrainment to RV apical entrainment in identifying the mechanism of SVT.

Methods: 42 consecutive patients with SVT undergoing catheter ablation were prospectively studied. Apical RV entrainment was performed 20 ms faster than tachycardia cycle length (TCL) initially followed by basal entrainment from the anteroseptal basal RV avoiding His or atrial capture. Postpacing interval (PPI), PPI-TCL, corrected PPI-TCL and Stim-A minus VA were measured.

Results: Entrainment was achieved from both sites of RV in 34 patients (10 men; mean age: 42±15 years), 20 with typical AVNRT, 1 with atypical AVNRT, and 13 with AVRT (8 left sided, 4 right sided, and 1 septal APs). PPI-TCL, cPPI-TCL and SA-VA were significantly longer with basal entrainment in AVNRT (171±30 vs 153±22 ms (p=0.003), 148±21 vs 131±20 ms (p=0.002) and 145±17 vs 136±15 ms (p=0.005) respectively). Receiver Operator Charecteristic (ROC) curves showed higher AUC for the above parameters with basal entrainment compared to apical entrainment. Basal PPI-TCL>110 ms had a sensitivity of 100% and a specificity of 84% for diagnosis of AVNRT. Basal cPPI-TCL>95 ms had a sensitivity of 100% and a specificity of 93% for diagnosis of AVNRT. Basal SA-VA>105 ms had a sensitivity of 100% and a specificity of 93% for diagnosis of AVNRT.

Conclusions: Entrainment from the anteroseptal basal RV is a simple maneuver that is superior to apical ventricular entrainment in identifying the mechanism of SVT.

Abstract

Negative effects on growth indices had been reported in children treated with interferon for chronic viral hepatitis. Forty chronic hepatitis C virus-infected adolescents, 12-17 years of age, were treated with sofosbuvir/daclatasvir therapy for 12 weeks. The intent-to-treat sustained virologic response rate at 12 weeks after end of treatment was 39/40 (97.5%). Unlike interferon-based therapy, we did not detect significant negative effects on linear growth or weight. Contrarily, a trend to increased appetite and insignificant weight gain was observed, but further larger studies are needed to confirm. See Video-Abstract, http://links.lww.com/ASAIO/A381.

OBJECTIVES: Dual sofosbuvir/daclatasvir (SOF/DCV) therapy is currently recommended by The European Association for Study of Liver (EASL) as an option for the treatment of chronic hepatitis C virus infection (HCV) in adults for all genotypes; however it is still not considered for patients younger than 18 years old. We aimed to test safety and efficacy of SOF/DCV in adolescent patients 12 to 17 years old with chronic HCV, genotype 4 infection.

METHODS: We conducted a prospective, uncontrolled, open-label multicenter study. A total of 30 chronic HCV infected adolescents, aged from 12 to 17 years old were included and treated with dual SOF/DCV for 12 weeks. Patients were monitored throughout the treatment and follow-up period for safety and efficacy outcome measures including the sustained virologic response 12 (SVR12) rate.

RESULTS: The Intention to treat (ITT) SVR12 rate was 29/30 (96.7%; 95% confidence interval (CI): 83.3 - 99.4%). The only patient who did not achieve SVR12 was lost to follow up after showing viral negativity at the end of treatment visit. While all the remaining 29 patients (100%, 95% CI: 88.3 - 100%) who completed the follow up visits achieved SVR12. All patients showed normalized liver enzymes with normal hematological, liver and renal function tests at the end of the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study.

CONCLUSIONS: Sofosbuvir/Daclatasvir combined therapy could be a safe and effective treatment in adolescent patients 12 to 17 years old with chronic HCV genotype 4 infection.

Yamamah, G. A. N., A. A. Talaat Abdel Alim, Y. S. E. D. Mostafa, R. A. A. S. Ahmed, A. M. Mohammed, and A. M. Mahmoud, "Prevalence of Visual Impairment and Refractive Errors in Children of South Sinai, Egypt.", Ophthalmic epidemiology, vol. 22, issue 4, pp. 246-52, 2015. Abstract

PURPOSE: To assess the prevalence and causes of visual impairment in children of South Sinai, and to evaluate outcomes of rehabilitation programs.

METHODS: Population-based, cross-sectional analysis of 2070 healthy school children screened for visual impairment from 2009 through 2010 in cities of South Sinai and their surrounding Bedouin settlements. Visual acuity (VA) was tested using Snellen charts followed by cycloplegic autorefractometry for cases with presenting VA ≤ 6/9. Appropriate eyeglasses were prescribed and VA re-evaluated.

RESULTS: This study included 1047 boys and 1023 girls, mean age 10.7 ± 3.1 years. Visual impairment (uncorrected VA ≤ 6/9) was detected in 29.4% of children, while 2.0% had moderate-severe visual impairment (uncorrected VA ≤ 6/24). There were statistically significant differences in prevalence of visual impairment between the studied cities (p < 0.05), with the highest prevalence in Abu Redis. Prevalence of visual impairment was significantly higher among girls (p < 0.05) and those with positive consanguinity (p < 0.05). Bedouin children showed significantly lower prevalences of visual impairment. Only age was a reliable predictor of visual impairment (odds ratio 0.94, p < 0.0001). Ophthalmic examination revealed other disorders, e.g. dry eye (4.74%), squint (2.37%), exophthalmos (1.58%) and ptosis (0.79%). VA significantly improved in children who received spectacles (p < 0.001).

CONCLUSION: A total of 29.4% of South Sinai children had some form of visual impairment, 90.32% of which comprised refractive errors (mainly astigmatism) which were significantly corrected with eyeglasses. VA screening and correction of refractive errors are of the utmost importance for ensuring better visual outcomes and improved school performance.
