Study Type – Therapy (case series) Level of Evidence 4 OBJECTIVE • To evaluate the safety and efficacy of ultrasonography (US)‐guided renal access in percutaneous nephrolithotomy (PCNL), as compared with conventional fluoroscopy‐guided renal access in a prospective randomized trial. PATIENTS AND METHODS • From January 2008 to October 2009, 224 patients with renal calculi undergoing PCNL were randomized into two groups. • Group 1 (112 patients) underwent PCNL using only fluoroscopy‐guided renal access; while in group 2 (112 patients), US guidance for puncture was used in addition to fluoroscopy. • The inclusion criteria were: normal renal functions, American Society of Anesthesiology scores 1 or 2, absence of congenital abnormalities, aged 15–70 years, and anticipated single‐tract procedure. The patients in both groups were matched for age, sex, and stone characteristics. • The Student t‐test was used for statistical analysis with an allowable error of 5%. RESULTS • The mean time to successful puncture was 3.2 min and 1.8 min in group 1 and group 2, respectively (P < 0.01). • The mean duration of radiation exposure to successful puncture was 28.6 s in group 1 and 14.4 s in group 2 (P < 0.01). • The mean numbers of attempts for successful puncture in the desired calyx was 3.3 in group 1 as compared with 1.5 in group 2 (P < 0.01). • The meantime taken for tract formation in group 1 was 7.4 min with radiation exposure of 82 s, while in group 2 it took 4.8 min with radiation exposure of 58 s (P < 0.01). • Successful access was achieved in all patients. All patients were stone‐free at the end of the operation. The hospital stay (2–3 days) was same in both groups. There was no incidence of significant bleeding requiring transfusion during or after surgery. All the patients were followed‐up for a ≥6 months. CONCLUSION • US‐guided puncture in PCNL helps in increasing accuracy of puncture and decreasing radiation exposure for the surgical team and the patients.

Objective:Prospective randomized study to compare the efficacy and safety of alfuzosin and tamsulosin in patients suffering from acute urinary retention caused by benign prostatic hyperplasia (BPH).Methods:Patients with acute urinary retention (AUR) due to BPH (total 150) were catheterized and randomized into three groups: Group A: alfuzosin 10 mg (50 patients), Group B: tamsulosin 0.4 mg (50 patients), Group C: placebo (50 patients). After three days, catheter was removed, and patients were put on trial without catheter (TWOC). Patients with successful TWOC were followed up for three months, taking into account the prostate symptom score (AUA Score), post-void residual urine volume (PVRV), and peak flow rate (PFR). ANOVA was used for statistical analysis.Results:Both group A (alfuzosin) and group B (tamsulosin) had similar results of TWOC (group A – 66%, group B – 70%), which were significantly superior than group C (placebo) – 36%. In follow up, three (9.1%) patients in group A, three (8.6%) patients in group B and eight (44.4%) patients in group C had retention of urine, requiring recatheterization. These patients were withdrawn from the study. After three months, alfuzosin- or tamsulosin-treated patients showed a significant decrease in AUA score and PVRV; and a significant increase in PFR as compared to placebo.Conclusions:TWOC was more successful in men treated with either alfuzosin or tamsulosin and the subsequent need for recatheterization was also reduced. Tamsulosin was comparable to alfuzosin in all respects, except a small but significant side effect of retrograde ejaculation.

Five percent phenol is a better sclerosant than 1% polidocanol and is as efficacious as operative treatment, with lesser morbidity and similar safety profile.

Dementia with the onset before the age of 65 years is classified as early-onset dementia. Although uncommon, it has considerable impact on the lives of patients and care givers, alike. A substantial subset of patients may have underlying reversible causes. Yet, many, especially those of the very young may be initially misdiagnosed. A case of young woman with rapid mental decay is described here. She was finally diagnosed with gliomatosis cerebri (GC) involving only right frontal lobe. This atypical radiological feature of GC with primary presentation as memory loss needs special attention and clinicians should be aware of such conditions.

Background: Debate encompasses the use of Vitamin E Polyethylene or conventional Polyethylene liner in primary hip arthroplasty. Does the Inclusion of Vitamin E in PE give adequate protection from oxidation and maintains lower rates of wear? Patients and methods: We performed this study following the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement (PRISMA) and the Cochrane Handbook for systematic reviews and meta-analysis. Studies were included from any region, written in any language. We had only the randomised control trials comparing the femoral head penetration between Vitamin-E diffused highly cross-linked polyethylene (VEPE) liner and conventional liners in primary total hip arthroplasty. Results: We included 10 studies in this meta-analysis. We conducted them using Review Manager V.5.0. We computed the risk ratio to measure the treatment effect, considering the heterogeneity. We used Random-effect models. VEPE had insignificant marginal advantages for FHP within three months post-operative. Additionally, VEPE showed significantly less FHP after two and five years. After one year, it showed significantly less FHP with the VEPE group versus the UHMWPE cohort and a non-significant difference between the VEPE and XLPE group. Conclusions: In terms of FHP, this metanalysis shows less FHP for the VEPE than conventional PE. A longer follow-up period is required to evaluate whether the oxidation protection gained by Vitamin E results in lower wear rates, less osteolysis, and aseptic loosening compared to the conventional PE in the long term.

Introduction: In children uncorrected refractive errors have a profound effect on educational and psychosocial development hence it is necessary to estimate the prevalence both at the community and at the school level to aid planning and implementation of refractive error services in children. Objective: To determine the refractive status of 5 to 15 years old children attending government schools of rural areas of district Agra, Uttar Pradesh (UP), India. Method: Study conducted on 902 students of age group 5-15 years of randomly selected government schools of Bichpuri Block of district Agra. Children underwent visual acuity assessment and torch light examination, height and weight measurement. Children with VA ≤6/9 were further examined and cycloplegic retinoscopy, fundus examination, slit lamp examination and post mydriatic refraction was done. On the basis of values of cycloplegic refraction and post mydriatic refraction, refractive error was classified as myopia, hypermetropia and astigmatism. Statistical Analysis was done by applying Chi square test. Result: Out of 902 children, 125 children (13.86 %) were having refractive error of which 76 were myopic (8.43%), 39 were astigmatic (4.32%) and 10 were hypermetropic (1.11%). There was an increase in the overall prevalence of refractive error with advancing age. There was no significant association of refractive error with gender and nutritional status. Conclusion: Vision screening of school children is very useful for early detection and correction of refractive errors. Screening of the refractive errors in school should be carried out periodically and regularly.
