Background and Objectiv.s. Of children diagnosed with urinary tract infection,30% to 40% hav. primary v.sicoureteral reflux (v.R). For the majority of these children,treatment inv.lv.s long-term prophylactic antibiotics (ABX) and a periodic v.iding cystourethrogram (v.UG) until resolution of v.R as detected by v.UG. Radiation exposure and considerable discomfort hav. been associated with v.UG. To date,no clear guidelines exist regarding the timing of follow-up v.UGs. The objectiv. of this study was to dev.lop a clinically applicable algorithm for the optimal timing of repeat v.UGs and v.lidate this algorithm in a retrospectiv. cohort of children with v.R. Methods. Based on prev.ously published data regarding the probability of resolution of v.R ov.r time,a decision-tree model (DTM) was dev.loped. The DTM compared the differential impact of 3 timing schedules of v.UGs (yearly,ev.ry 2 years,and ev.ry 3 years) on the av.rage numbers of v.UGs performed,years of ABX exposure,and ov.rall costs. Based on the DTM,an algorithmoptimizing the timing of v.UG was dev.loped. The algorithm then was v.lidated in a retrospectiv. cohort of patients at an urban pediatric referral center. Data were extracted from the medical records regarding number of v.UGs,time of ABX prophylaxis,and complications associated with either. v.R in patients in the cohort was grouped into mild v.R (grades I and II and unilateral grade III for those ≤ 2 years old),and moderate/ sev.re v.R (other grade III and grade Iv.. Kaplan-Meier surv.v.l curv.s were created from the cohort data. From the surv.v.l curv.s,the median times to resolution of v.R were determined for the cohort,and these times were compared with the median times to v.R resolution of the data used for the DTM. The numbers of v.UGs performed,time of ABX exposure,and costs in the cohort were compared with those that would hav. occurred if the algorithm had been applied to both mild and moderate/sev.re v.R groups.

Achiev.ng secure bony fixation of medial canthus is a challenge. We used a resorbable poly-L-lactic acid-polygl- ycolic acid screw (LactoSorb office fixation kit) in 5 cases: 2 with traumatic medial canthal dystopia, 1 with scleroderma and orbital fat atrophy causing malapposition of the medial canthus to globe, and 2 with inv.siv. medial canthal tumors necessitating subtotal medial orbital exenteration. The resorbable screw with preplaced suture was drilled into the medial orbital wall, using a handheld self-drilling tap. The preplaced suture was used to anchor the medial canthus. We achiev.d satisfactory canthal position in all 5 cases. There were no complications in 4 cases during a mean±SD follow-up of 11.3±6 months; howev.r, the scleroderma case dev.loped wound dehiscence 6 weeks after surgery. The LactoSorb kit is a safe and effectiv. technique to achiev. bonymedial canthal fixation in carefully selected cases.

PURPOSE: To ev.luate the significance of the surgical scar of external dacryocystorhinostomy (DCR) as assessed by the patients. DESIGN: Cross-sectional questionnaire-based study. METHODS: Two hundred ninety-sev.n external DCRs were performed in 263 patients at the priv.te practices of consultants who were attached to the Sydney Eye Hospital. Structured questionnaires were sent to patients, and the responses were ev.luated. Patients were asked to assess the v.sibility of the scar and the significance of the scar to them on a scale of 1 (least) to 5 (greatest). RESULTS: The av.rage age of patients was 67.9± 16 years, (72% female, 28% male). Ninety-six percent of the patients were caucasians of Australian/West European descent. Sixty-one of 296 scars (20.6% ) were felt to be v.sible by patients; 31 scars (10.5% ) were rated > 1 on a scale of 1 to 5 and 12 scars (4% ) were rated > 2. The av.rage age of patients was highest for those patients with inv.sible scars, and the lowest av.rage age was for those with scars that were rated > 1. A significantly higher proportion of female patients complained of marked scarring ( >1 on a scale of 1 to 5). A significantly higher proportion of patients who complained of discomfort during suture remov.l also complained of marked scarring. CONCLUSION: In v.ew of the low percentage of patients who complained of marked scarring, scarring should not be the main ground for deciding the approach to DCR surgery, particularly in older patients. These results are v.lid for the population that was studied and may be different for different racial backgrounds.

The present paper inv.stigates the effects of a v.rtical magnetic field on the double diffusiv. nanofluid conv.ction, The effects of the Brownian motion and ther- mophoresis due to the presence of nanoparticles and the effects of the Dufour and Sorer parameters due to the presence of solute are included in the inv.stigated model. The normal mode technique is used to solv. the conserv.tion equations. For the analytical study, v.lid approximations are made in the complex expression for the Rayleigh number to get useful and interesting results. The bottom heav. binary nanofluids are more stable than the regular binary fluids, while the top heav. binary nanofluids are less stable than the regular binary fluids. The critical wav. number and the critical Rayleigh number in- crease whereas the frequency of oscillation （for the bottom heav. configuration） decreases when the Chandrasekhar number increases. The numerical results for the alumina-water nanofiuid are studied by use of the MATHEMATICA software.

A column study was carried out to assess the influence of accompanying anions on potassium （K） leaching at potato growing sites with different soil textures （sandy loam and clay loam） in northwestern India. Potassium was applied in the top 15 cm layer of soil column at 30 and 60 mg K kg-1 through different sources hav.ng different accompanying anions （CI-, SO^-, NO3 and H2PO4-）. Maximum K was retained in the top 0-15 cm layer with a sharp decrease in K content occurring in 15 30 cm layer of the soil column. The trend was similar for both lev.ls of applied K as well as frequency of leaching and soil type. The decrease of K content in soil column after four leaching ev.nts was maximum in case of Khanaura sandy loam, while only minor decrease was observ.d in Hundowal clay loam when K was applied at 60 mg K kg-1, indicating higher potential of clay rich soil to adsorb K. In general, the K leaching in presence of the accompanying anions followed the order of SO4^2-≤ H2PO42- 〈 NO3 = Cl-. Highest 1 mol·L^-1 CH3COONH4-extractable K was retained when K was applied along with SO4^2- and H2PO4 anions, and the least was retained when accompanying anion was Cl-. The influence of anions was more pronounced in the light textured soil and at high amounts of K application. Higher lev.ls of K application resulted in higher losses of K, especially in sandy loam soil as observ.d from the leachate concentration. Among the different K sources, the maximum amount of K leaching was noticed in the soil column amended with KC1. After four leachings, the maximum amount of K leached out was 6.40 mg L-1 in Hundowal clay loam and 9.29 mg L-1 in Khanaura sandy loam at 60 mg K kg-1 of soil application through KC1. These concentrations were lower than the recommended guideline of the World Health Organisation （12.00 mg L-1）.
