Introduction: Chronic hepatitis C (CHC) infection is an important cause of chronic and end stage liver disease. Treatment response has improved with combination therapy. We review our experience with combination therapy in CHC patients. Materials and Methods: All patients who had completed at least one course of combination therapy (> 6 months) and had longer than 6 months of follow-up were retrospectively reviewed. Results: There were 28 (22 males, mean age 40.7 ± 9.9 years old) patients who completed one course of treatment. Intravenous drug use (IDU) accounted for 61% of the aetiology. The end of treatment biochemical response was 92.6%. The overall sustained viral response (SVR) was 64.3%. Comparing IDU to the others (non-IDU), there was no difference in treatment SVR (64.7% vs. 63.6%, p = 0.954). Responders had significantly higher pretreatment serum alanine aminotransferase (p = 0.018). Overall treatment side effects were observed in 64% (flu-like symptoms 58.3%, haematological 50% and depressive mood 8%). Conclusions: Our response rates are comparable to published data. There was no difference in treatment response rate between the IDU and non-IDU. CHC infected IDU should be offered treatment.

Beta blockers are one of the commonest prescription drugs in medicine and they have been thought to revolutionize the treatment of heart failure (HF) with reduced ejection fraction (HFrEF) in the last century. In addition to HFrEF, they are prescribed for a variety of diseases in cardiology from hypertension to HF, angina, and stable coronary artery disease (CAD). The increased prescription of beta blockers in conditions like HF with preserved ejection fraction (HFpEF), and stable CAD may be doing more harm than good as per the data we have so far. The available data shows that beta blockers are associated with increased stroke risk and atrial fibrillation (AF) in hypertension and in patients with HFpEF, they have been associated with decreased exercise capacity. In patients with stable CAD and patients with myocardial infarction with normal systolic functions, beta blockers don’t offer any mortality benefit. In this article, we critically review the common indications and the uses of beta blockers in patients with HFpEF, CAD, hypertension and AF and we propose that beta blockers are overprescribed under the shadow of their beneficial effects in patients with HFrEF.

This cross sectional study investigated the clinical and radiographic status of crowned teeth with and without
root canal treatment. The study used secondary data from records of patients who received crown treatment
at the Faculty of Dentistry, University of Malaya before 2015 and walk-in patients attending the primary care
clinic between July - December 2016. The inclusion criterion was crown fitted for more than 12 months. Once
identified, the patients were assessed for clinical and radiographic status. Data were entered into and
analysed using SPSS Version 20 software. A total of 66 crowns [35 root canal treated (RCT) and 31 non-root
canal treated (n-RCT)] were identified. Chi-square test was carried out to determine the health of crowned
teeth and for its longevity in the oral cavity. There were 43 crowns (46.5% RCT; 53.5% n-RCT) with plaque
accumulation, 15 (66.7% RCT; 33.3% n-RCT) with gingival swelling/recession, 17 (46.5% RCT; 53.5% n-RCT)
with widening of the periodontal ligament, 13 (53.8% RCT; 46.2% n-RCT) with bone loss and 5 (60% RCT; 40%
n-RCT) crowns with periapical lesion. There was no statistically significant difference except for poorer
alveolar bone condition for crowns that have been in the mouth for >10 years. Based on the study, no
significant adverse pulpal involvement between crown with RCT and crown without RCT was observed.

OBJECTIVETo assess the correlation between five anthropometric parameters and the distance from tibial tuberosity to medial malleolus in 100 volunteers.
METHODSSix anthropometric parameters were measured in 50 male and 50 female medical students using a metallic scale: medial knee joint line to ankle joint line (K-A), medial knee joint line to medial malleolus (K-MM), tibial tuberosity to ankle joint (TT-A), tibial tuberosity to medial malleolus (TT- MM), olecranon to 5th metacarpal head (O-MH) and body height (BH). Nail size predicted based upon TT-MM measurement was chosen as ideal nail size. A constant was derived for each of the six anthropometric parameters which was either added or subtracted to each measurement to derive nail size. A regression equation was applied to BH measurements. Nail sizes calculated were compared with that obtained from TT-MM measurement and accuracy was evaluated. Accuracy of O-MH and BH regression equations recommended by other authors were calculated in our data.
RESULTSAdding 11 mm to TT-A distance had highest accuracy (81%) and correlation (0.966) in predicting nails correctly. Subtracting 33 mm from K-MM measurement and 25 mm from K-A distance derived accurate sizes in 69% and 76% respectively. Adding 6 mm to O-MH distance had a poor accuracy of 51%. Nail size prediction based upon body height regression equation derived correct nail sizes in only 34% of the cases. Regression equation analysis by other authors based on O-MH and BH distances yielded correct sizes in 11% and 5% of the cases respectively.
CONCLUSIONTT-A, K-A and K-MM measurements can be used simultaneously to increase accuracy of nail size prediction. This method would be helpful in determining nail size preoperatively especially when one anatomic landmark is difficult to palpate.

In the last three decades, significant advances have been made in the care of children requiring renal replacement therapy (RRT). The move from the use of only hemodialysis and peritoneal dialysis to continuous venovenous hemofiltration with or without dialysis (continuous renal replacement therapy, CRRT) has become a mainstay in many intensive care units. The move to CRRT is the result of greater clinical experience as well as advances in equipment, solutions, vascular access, and anticoagulation. CRRT is the mainstay of dialysis in pediatric intensive care unit (PICU) for critically ill children who often have hemodynamic compromise. The advantages of this modality include the ability to promote both solute and fluid clearance in a slow continuous manner. Though data exist suggesting that approximately 25% of children in any PICU may have some degree of renal insufficiency, the true need for RRT is approximately 4% of PICU admissions. This article will review the history as well as the progress being made in the provision of this care in children.

Objective:
To systematically review studies on canine agenesis prevalence in different populations and continents, based on the jaw, sex, location, and associated dental anomalies.
Methods:
Electronic and hand searches of English literature in PubMed, Web of Science, Scopus, OpenGrey, and Science Direct were conducted, and the authors were contacted when necessary. Observational studies (population-based, hospital/clinic-based, and cross-sectional) were included. For study appraisal and synthesis, duplicate selection was performed independently by two reviewers. Study quality was assessed using a modified Strengthening the Reporting of Observational Studies in Epidemiology checklist, with main outcome of prevalence of canine agenesis.
Results:
The global population prevalence of canine agenesis was 0.30% (0.0−4.7%), highest in Asia (0.54%), followed by Africa (0.33%), and the least in Europe and South America (0.19% in both continents). Canine agenesis was more common in the maxilla (88.57%), followed by both maxilla and mandible (8.57%), and the least common was mandible-only presentation (2.86%). The condition was more common in females (female:male ratio = 1.23), except in Asia (female:male ratio = 0.88) and Africa (female:male ratio = 1). In Asia, unilateral agenesis was almost twice as prevalent as bilateral, but in Europe, the bilateral form was more common.
Conclusions
The overall prevalence of canine agenesis is 0.30%, with the highest prevalence in Asia, followed by Africa, Europe, and South America.The condition is more common in the maxilla than the mandible, and in females than males (except in Asia and Africa), with unilateral agenesis being more common in Asia and the bilateral form showing a greater prevalence in Europe.

Background:
This is a rare and challenging case of Wolff–Parkinson–White syndrome due to a posteroseptal acces‑ sory pathway located in the coronary sinus diverticulum. It is often difficult to precisely locate this type of accessory pathway, and the ablation procedure could be associated with collateral damage to the neighbouring coronary arteries.Case Presentation: The patient was a 49-year-old female with Wolff–Parkinson–White syndrome who was referred for catheter ablation. She had had a previous unsuccessful attempt at ablation and had remained symptomatic despite drug therapy. The pre-procedural cardiac computed tomography scan revealed the presence of a diverticu‑ lum in the proximal coronary sinus. Using an advanced three-dimensional cardiac mapping system, the electroana‑ tomic map of the diverticulum was created. The accessory pathway potential was identified within the diverticulum preceding the ventricular insertion. The accessory pathway was then successfully ablated using radiofrequency energy.
Conclusion
We have demonstrated that the advanced three-dimensional cardiac mapping system plays a very important role in guiding clinicians in order to precisely locate and safely ablate this type of challenging accessory pathway.
