Background: Over the course of the thrombectomy procedure, clot fragments may become dislodged and lead to downstream emboli due to manipulation of an endovascular device. The EmboTrap thrombectomy system features an inner stent channel with an outer stent trap design that may potentially reduce the risk of distal clot fragmentation during clot removal. We tested the hypothesis that distal emboli to both the same and new territory generated during mechanical thrombectomy are a function of device design. Methods: EmboTrap and Solitaire thrombectomy were conducted in an in vitro model system that mimicked a middle-cerebral artery (MCA) occlusion within a complete circle of Willis vascular replica and a contrast-enhanced clot analog. Emboli generated during the procedure with a size >1,000 μm were collected and measured with calipers. The Coulter principle was used to characterize emboli with a size between 200 and 1,000 µm. Results: EmboTrap thrombectomy resulted in a significant reduction in the risk of large emboli (>1,000 μm) formation as compared to first-generation stent retriever thrombectomy (p = 0.031, Fisher exact test). The majority of emboli >1,000 μm (∼80%) were found in the MCA, regardless of device type. There was no significant difference between the EmboTrap and Solitaire in 200 to 1,000 μm emboli formation (p = 0.89, Mann-Whitney test). When combining all emboli in the most dangerous range (>200 μm), EmboTrap offered a size reduction of emboli (p = 0.022). Conclusion: The risk of distal embolization can be altered with improved stent retriever design. When encountering fragment-prone clots, EmboTrap thrombectomy may lower the risk of distal embolization.

White-tailed deer (WTD) invitro embryo production is not well documented, due to the seasonality of the wildlife species and available hunting permits. The objective of the present study was to conduct IVM and IVF using WTD oocytes vitrified with trehalose (TH) or sucrose (SC). A total of 121 immature oocytes were obtained from ovaries (n=18) using the slicing technique from hunter-slaughtered deer, not more than 2h after death. The WTD oocytes were vitrified using a solid surface vitrification technique in two different groups: 1) TH (n=60) and 2) SC (n=61). Oocyte warming (OW) was done using four concentrations (OW1 1 M, OW2 0.5 M, OW3 0.25 M, and OW4 0 M) in the oocytes after thawing. Then, a sample was used to evaluate viability for TH (n=5) and SC (n=5) (MTT stain (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), 0.5mgmL−1) and nuclear status (NS) for TH (n=4) and SC (n=5) with 4′,6-diamidino-2-phenylindole (1μgmL−1), defining the stage as germinal vesicle (GV), MI, and unable to evaluate (NE). The remaining oocytes (n=88) were used for IVM for 36h in tissue culture medium-199 supplemented with human menopausal hormone (75 UImL−1) and epidermal growth factor (10ngmL−1). The evaluation of NS was defined (GV, MI considered immature and MII matured). The IVF (n=15) took place in Tyrode's albumin lactate pyruvate media supplemented with heparin (10μgmL−1), penicillamine (0.075mgmL−1), hypotaurine (10M), epinephrine (1μM), and bovine serum albumin fraction V (0.4%), with a final semen concentration of 3×106 spermmL−1. Frozen straws of conventional WTD semen were used; the straws were split into 3 parts, with one fraction thawed and capacitated using “swim-up” technique. After 24h of incubation at 38.5°C with 5% CO2, and humidified air, nuclear evaluation was made as fertilized (F), not fertilized (NF), or NE. A Fisher exact test was used (SAS, 9.0 version for Windows), α=0.05. After warming, for the TH group (n=5), viability was 60% and nuclear status (n=4) was 50% GV, 50% MI, and 0% NE. For the SC group (n=5), viability was 40% and nuclear status (n=5) was 60% GV, 20% MI, and 20% NE. After 36h IVM, NS evaluation in the TH group (n=38) was 66% GV, 24% MI, 0% MII, and 10% NE; for the SC group (n=50), 84% GV, 10% MI, 2% MII, and 4% NE, not a statistically significant difference (P>0.05). For IVF after 24h, the NS evaluation in the TH treatment (n=10) was 0% F, 60% NF, and 40% NE versus the SC treatment (n=5) with 20% F, 40% NF, and 40% NE, not a statistically significant difference (P>0.05). A statistically significant difference (P>0.05) was not found between the TH and SC groups with regard to post-thaw viability, IVM, and IVF. Future research with larger numbers of immature or mature oocytes is suggested for further evaluation of both TH and SC for WTD oocyte vitrification for use with invitro-production techniques as a model for other endangered cervid species.

Background:Systemic lupus erythematosus (SLE) has a significant genetic predisposition. Many genetic variants of susceptibility to SLE have been published and analyzed, but the clinical and functional significance of the various genotypes has not yet been clearly defined [1].Objectives:To estimate the association between some of non-HLA gene polymorphisms such as STAT4 rs7574865, RUNX1 rs9979383, IL6 rs1800795, IL6R rs2228145, IL6R rs4845618 and susceptibility to SLE in Belarusian population as well as some disease manifestations.Methods:We examined 383 healthy blood donors and 54 SLE patients (18-72 years old, median age 35) classified according to the 1997 American College of Rheumatology (ACR) revised classification criteria [2]. Deoxyribonucleic acid was extracted from peripheral blood samples by phenol-chloroform method. Genotyping was performed by real-time PCR with fluorescent probes. Differences of distribution of all the single nucleotide polymorphism (SNP) genotypes and their associations with secondary antiphospholipid syndrom (APS) and lupus arthritis were analyzed using Pearson χ2 (χ2) and two-way Fisher exact test (F, p2-t). Diagnostic odds ratio (dOR), likelihood ratio of positive (LR +) and negative (LR –) tests and corresponding 95% confidence intervals (CI) were also calculated.Results:We revealed significant difference in STAT4 rs7574865 genotypes in SLE patients and healthy donors (χ2=8,27, р=0,016) with significant increase of ТТ genotype frequency in SLE patients vs healthy donors (χ2=6.83 p=0.009; p2-t =0.020; dOR=3.78 (CI95% 1.36-10.55); LR+ =3.44 (CI95% 1.35-8.71); LR– =0.91 (CI95% 0.83-0.98)). Lupus arthritis was more common in risk TT-genotype SLE carriers than in other SLE patients (χ2=5.902 p=0.015; p2-t =0.027).We revealed significant increase of СТ genotype (RUNX1 rs9979383) in healthy donors vs SLE patients (χ2=4.14; p=0.042; dOR=0.53 (CI95% 0.29-0.98); LR+ =0.69 (CI95% 0.45-0.99); LR– =1.3 (CI95% 1.01-1,56)). Lupus arthritis was more common in SLE СТ-genotype carriers than in other SLE patients (χ2=4.66 p=0.031; p2-t =0.058).Significant differences in IL6 rs1800795, IL6R rs2228145 and IL6R rs4845618 genotypes distribution between studied groups were not found (χ2, p=0.427, p=0.559 and p=0.407, correspondingly) but GG-genotype (IL6 rs1800795) carriership in SLE patients was associated with increased APS frequency (χ2=4.45, p=0.035; dOR=0.19 (CI95% 0.04-0.9); LR+ =0.28 (CI95% 0.07-0.93); LR– =1.41 (CI95% 1.03-1.64).Conclusion:Our data suggest the susceptibility to SLE in ТТ genotype of STAT4 rs7574865 polymorphism, protective role of СТ genotype of RUNX1 rs9979383 for SLE and association between GG-genotype of IL6 rs1800795 and APS in SLE patients in Belarusian population. Lupus arthritis was associated with ТТ genotype of STAT4 rs7574865 and СТ genotype of RUNX1 rs9979383.References:[1]Chen L, Morris DL, Vyse TJ.

Objectives- Evaluate the perception of the female chin attractiveness by maxillofacial surgeons, orthodontists and lay people through simulations of mentoplasty performed with the aid of a software. Profile photography along with lateral face teleradiography were manipulated using Dolphin Imaging Software version 11.8, and different clinical situations were designed. Methods: The alterations were performed with anteroposterior movements, with images of mentoplasty of advancement (+2, +3 and +4), and recoil (-2, -3, -4). The reference of the movement was given in relation to the True Vertical Line (TVL). Ninety people were interviewed. 30 orthodontists, 30 maxillofacial surgeons and 30 lay people. They observed the photos and classified the profile according to extremely pleasant, pleasant, unpleasant and extremely pleasant. To evaluate the presence of significant difference between the groups in relation to the profile analysis, the Fisher Exact test was used. Results: Most lay people, surgeons and orthodontists (46%) considered the chin at the limit of the TVL as an extremely attractive profile. 34.4% considered the chin 2 mm before the TVL as an attractive profile; chin 3 mm beyond the TVL as unattractive (45.5%), and the most unattractive ones were 4 mm beyond the TVL (75.6%). Conclusion: So the great majority of the people interviewed showed a preference for the positioning of the chin in the TVL or slightly Class II profile in female patients, which can guide professionals in a better planning.

Aim. The purpose of this in vitro study was to assess the antimicrobial efficacy of Biopure MTAD against E. faecalis in contaminated root canals. Materials and Methods. Forty-two single rooted extracted human teeth were inoculated with E. faecalis and incubated for four weeks. The samples were divided in two control and five experimental groups irrigated with 1.5% sodium hypochlorite solution (NaOCl); 3% NaOCl; BioPure MTAD; 1.5% NaOCl/17% EDTA; or 3% NaOCl/17% EDTA. After a one-week incubation, complete disinfection was confirmed by the absence of turbidity in the incubation media. Dentin shavings were taken from samples with no turbidity to verify whether E. faecalis was present in dentin tubules. Results were analyzed statistically using Fisher's exact test, with the level of significance set at . Results. Statistical analysis of the data obtained at Day 7 and after dentin shaving analysis showed that BioPure MTAD had significantly greater antibacterial activity than 1.5% NaOCl, 1.5% NaOCl/17% EDTA and 3% NaOCl/17% EDTA. No significant difference was detected between MTAD and 3% NaOCl. Conclusions. These findings suggest that BioPure MTAD possesses superior bactericidal activity compared with NaOCl and EDTA against E. faecalis.

Objectives The purpose of this study is to test venous valve performance and identify differences between native tissue and replacement devices developed with traditional tissue treatment methods using a new in vitro model with synchronized hemodynamic parameters and high-speed valve image acquisition. Methods An in vitro model mimicking the venous circulation to test valve performance was developed using hydrostatic pressure driven flow. Fresh and glutaraldehyde-treated vein segments were placed in the setup and opening/closing of the valves was captured by a high-speed camera. Hemodynamic data were obtained using synchronized hardware and virtual instrumentation. Results Geometric orifice area and opening/closing time of the valves was evaluated at the same hemodynamic conditions. A reduction in geometric orifice area of 27.2  ± 14.8% (p < 0.05) was observed following glutaraldehyde fixation. No significant difference in opening/closing time following chemical fixation was observed. Conclusions The developed in vitro model was shown to be an effective method for measuring the performance of venous valves. The observed decrease in geometric orifice area following glutaraldehyde treatment indicates a decrease in flow through the valve, demonstrating the consequences of traditional tissue treatment methods.

Introduction: Seasonal hyper-acute panuveitis (SHAPU) is a sight-threatening disease and its management is challenging. Objective: To study the profile and evaluate the visual outcome of the patients of clinicallydiagnosed cases of SHAPU after treatment. Subjects and methods: A retrospective interventional hospital-based study was carried out involving 21 subjects with clinically-diagnosed SHAPU. The data were retrieved from the record section of the hospital and analyzed. The variables studied were demographic pattern, clinical condition, duration of presentation and visual acuity before and after the treatment. Statistics: The data were analyzed using Epi Info version 2000. Percentage prevalence, mean values with standard deviation, relative risk, 95% CI and p value were calculated. P value of < 0.05 was considered to be significant. Results: Among the 21 cases, the numbers of male and female were 11 (52.4 %) and 10 (46.7 %) respectively. A comparative analysis of gender in children and adults did not show any significant difference (RR=0.47, 95% CI = 0.22 - 1.01, Fisher exact test: p = 0.14). The mean for all ages was 7 ± 12.68 years, while the mean age in pediatric cases was 4.5 ± 3.91 years. Thirteen (61.9%) cases occurred in children below fifteen years. Fifteen (71.4 %) cases reported during September and October. Presenting visual acuity of all cases was less than 3/60. All of them received medical treatment. By the end of the 4th week, seven (33.3 %) patients regained vision to 6/18. Conclusion: SHAPU is more prevalent in pediatric age group. It is equally prevalent among males and females. The visual acuity can improve with early medical treatment. Keywords: SHAPU; panuveitis; steroid; phthisis bulbi DOI: 10.3126/nepjoph.v2i1.3702 Nep J Oph 2010;2(1) 35-38

The Common

Most current guidelines recommend prescribing second-generation antihistamines (SGAs) over first-generation antihistamines because SGAs are less likely to cause sedation and impairment of heavy work performance. However, common residents who use these antihistamines as over-the-counter (OTC) medicines are less likely to know that. So, this study was designed to compare the over-the-counter use of antihistamines by common residents with the prescribing preferences of physicians residing at Dhaka City, Bangladesh. Between June and August of 2017, a total of 100 Physicians from some of the top medical institutions of the city and 350 randomly selected common residents were directly interviewed with two separate semistructured questionnaires specifically designed for each population. Data was statistically analyzed using Fischer’s exact test, Spearman’s rank correlation test and Kendall’s tau rank correlation test. The data shows that physicians prefer second-generation antihistamines with fexofenadine (48.09% of the total responses), desloratadine (16.03%), and rupatadine (13.74%) taking the top spots. Cetirizine (29.46% of total responses), desloratadine (14.73%), and chlorpheniramine (14.52%) were the most used OTC antihistamines by the common residents. Statistical analysis with Fischer’s exact test revealed that the difference in preference of first-generation antihistamines between physicians and common residents were extremely significant (p<0.0001). Furthermore, cetirizine (which is known to have some degree of sedating activity) and chlorpheniramine are more preferred among common residents than among physicians (extremely significant difference, p<0.0001 in both cases). The study concludes that physicians of Dhaka City are complying with practice guidelines, but sedating antihistamines still retain some popularity among the common residents. Hence, a more engaging community pharmacy is needed to minimize adverse effects that can arise from OTC use of sedating antihistamines.

Introduction: The objective of this prospective study was to examine whether thromboelastogram (TEG) can predict the presence of venous thromboembolism (VTE) in patients who arrive at the emergency room with signs/symptoms that raise the suspicion of acute VTE. Methods: Every patient was tested for D-dimer and all TEG parameters, including: reaction time, clot time formation, alpha-angle, maximal amplitude, clot viscoelasticity, coagulation index, and clot lysis at 30 min. For categorical variables, χ2 or the Fisher exact test were used, and for continuous variables the t test or other non-parametric tests were used. Results: During 2016, a total of 109 patients were enrolled with a median age of 55.7 (21–89) years. Eighteen patients were diagnosed with VTE. Analyzing the different TEG parameters, both as continuous and categorical variables, did not reveal a statistically significant difference between VTE-positive and VTE-negative patients. Combining different TEG parameters or dividing the cohort according to gender, clinical suspicion of VTE (Well’s criteria), or different levels of D-dimer did not change the results of the analysis. Conclusion: The current study could not demonstrate a significant value of any TEG parameter as a predictor of VTE among patients who came to the emergency room with signs/symptoms that raise the suspicion of VTE.

Objective. The objective is the investigation of Joint Hypermobility (JH) and the Hypermobility Syndrome (HMS) in patients with inflammatory bowel disease (IBD).Methods. We examined 83 patients with IBD and 67 healthy individuals for the presence of JH. Patients were excluded if they were under 18 or over 50 years of age and if they had other conditions which affect joint mobility. Thex2and the Fisher exact test were used appropriately between study groups. Odds ratios (ORs) for the risk of JH and HMS in IBD groups were calculated.Results. A total of 150 individuals (83 IBD patients and 67 healthy controls) participated in the study. 69 IBD patients, 41 with Crohn's Disease (CD) and 28 with ulcerative colitis (UC), were finally eligible. JH was detected in 29 CD patients (70.7%), in 10 UC patients (35.7%), and in 17 healthy control subjects (25.4%). Significant difference was detected on JH in CD patients as compared to UC patients (P=.0063) and controls (P<.0001). The estimated OR for JH was 7.108 (95% CI: 2.98–16.95) in CD and 1.634 (95% CI: 0.63–4.22) in UC patients. HMS was detected in 5 (12.2%) CD and in 1 (3.57%) UC patients. The OR for HMS in CD was 3.75 (95% CI: 0.41–34.007), while 7 (17.1%) CD patients had overlapping symptoms for both HMS and early spondylarthropathy.Conclusions. JH and the HMS are common in CD patients, thus articular manifestations should be carefully interpreted. This implies an involvement of collagen varieties in the pathogenesis of IBD.

Aim.Efficacy of granisetron and combination of granisetron and dexamethasone was evaluated for prevention of postoperative nausea and vomiting (PONV) in children undergoing elective strabismus surgery.Methods.A total of 136 children (1–15 years) were included. Children received either granisetron (40 mcg/kg) [group G] or combination of granisetron (40 mcg/kg) and dexamethasone (150 mcg/kg) [group GD]. Intraoperative fentanyl requirement and incidence and severity of oculocardiac reflex were assessed. PONV severity was assessed for first 24 hours and if score was >2, it was treated with metoclopramide. Postoperative analgesia was administered with intravenous fentanyl and ibuprofen.Results.The demographic profile, muscles operated, and fentanyl requirement were comparable. Complete response to PONV in first 24 hours was observed in 75% (51/68) of children in group G and 76.9% (50/65) of children in group GD, which was comparable statistically (p=0.96, Fisher exact test; OR 1.11, 95% CI 0.50, 2.46). Incidence of PONV between 0 and 24 hours was comparable. One child in group G required rescue antiemetic in first 24 hours and none of the children had severe PONV in group GD. There was no significant difference in incidence or severity of oculocardiac reflex.Conclusion.Dexamethasone did not increase efficacy of granisetron for prevention of PONV in elective pediatric strabismus surgery. Registration number of clinical trial wasCTRI/2009/091/001000.
