Purpose. The aim of the study was to assess the performance of Airway Scope (AWS) on the first attempt at intubation in manikins by nonexpert physicians. Methods. A randomized crossover trial involving seven scenarios. Participants: residents of a cardiovascular hospital. In group A, the AWS procedure was performed first followed by Machintouch Laryngoscopy (ML), while in group B the ML procedure was performed first and then the AWS. The primary outcome assessed was the success of first intubation attempt in a normal scenario. The secondary outcome assessments were success in six other scenarios, and also elapsed time and dental trauma caused in all scenarios. Results. There were 34 participants. All AWS-assisted intubations were successfully completed, but one ML-assisted intubation failed in the normal scenario (P=0.32). The outcomes achieved by the AWS in scenarios involving cervical immobilization (P=0.03), tongue edema (P≤0.001), pharyngeal obstruction (P≤0.001), and jaw trismus (P=0.001) were superior to those obtained with the ML. Conclusions. Use of AWS-assisted intubation in manikin scenarios results in a significantly high intubation success rate on the first attempt by nonexpert physicians. These findings suggest this new device will be useful for nonexpert physicians in emergency situations.

Abstract Background This in-vitro study aims to assess the efficacy of a novel radiographic grid aiming device as compared to the conventional “bull’s eye” puncture technique for percutaneous renal puncture. Methods This new device uses two radiopaque rings for targeting, somewhat similar to the concept of gun sights. The device is designed to improve the ease and accuracy of the “bull’s eye” puncture technique. We compared this device to the conventional “bull’s eye” puncture technique using a porcine kidney inside a chicken carcass as the study model. Two first-year residents used both the radiographic grid aiming device in turn, Group A, and the conventional bull’s eye technique, Group B, to perform punctures to reach the target porcine calyces in order. Related data were recorded and analyzed. Results 23 renal calyceal punctures were performed per group. There were no statistical differences in the overall puncture success rate, puncture time, or radiation exposure time and dose between the two groups. The number of punctures required to achieve success was higher in group B and the distance between the puncture site to the center of papillary fornix was shorter in group A, all P < 0.05. Conclusions The novel radiographic grid aiming device showed no advantage in the overall success rate for renal puncture. However, it offered the advantages of more precise puncture with fewer puncture attempts. It may serve as a useful tool for training. It may also offer some benefit to surgeons who are novices at percutaneous renal puncture.

AbstractWe investigated the effects of stent generation on 2-year clinical outcomes between prediabetes and diabetes patients after acute myocardial infarction (AMI). A total of 13,895 AMI patients were classified into normoglycemia (group A: 3673), prediabetes (group B: 5205), and diabetes (group C: 5017). Thereafter, all three groups were further divided into first-generation (1G)-drug-eluting stent (DES) and second-generation (2G)-DES groups. Patient-oriented composite outcomes (POCOs) defined as all-cause death, recurrent myocardial infarction (Re-MI), and any repeat revascularization were the primary outcome. Stent thrombosis (ST) was the secondary outcome. In both prediabetes and diabetes groups, the cumulative incidences of POCOs, any repeat revascularization, and ST were higher in the 1G-DES than that in the 2G-DES. In the diabetes group, all-cause death and cardiac death rates were higher in the 1G-DES than that in the 2G-DES. In both stent generations, the cumulative incidence of POCOs was similar between the prediabetes and diabetes groups. However, in the 2G-DES group, the cumulative incidences of Re-MI and all-cause death or MI were significantly higher in the diabetes group than that in the prediabetes group. To conclude, 2G-DES was more effective than 1G-DES in reducing the primary and secondary outcomes for both prediabetes and diabetes groups.

Background: ovarian follicular quality diminishes with age, Free radicals and oxidative stress begin to accumulate in cells, aging or slowing down the metabolic energy production centers in the cell- the mitochondria. When the mitochondria cannot generate a certain amount of energy, it slows growth and proper development of the follicle making it more prone to DNA damage, including chromosomal abnormalities resulting in poor fertilization patterns, and early miscarriage. Co-enzyme Q10 (CoQ10) is a major cellular antioxidant. its tissue levels gradually decrease with age. We attempt to evaluate its protective effect on ROS-induced ovarian damage, which is one of the most important and widely accepted patho- mechanisms underlying cell ageing.Methods: 40 Participants   from El Shatby hospital infertility clinic 35 to 38 years old, with history of bad response to ovulation stimulation, were divided into two equal groups (group A given (CoQ10) 3mg|kg body weight for three cycles prior to stimulation Serum anti- mullarian hormone level was measured before and after CoQ10 administration, group B= twenty cases as control). Participants were given gonadotrophins (150 IU to 375 IU). Follicular growth was monitored by trans- vaginal ultra- sonography and serum estradiol level (E2). Ovulation trigger was achieved using 10,000 IU of human chorionic gonadotrophin.Results: The primary outcome was occurrence of normal pregnancy; secondary outcome was good response to stimulation (at least one mature follicle 18-22mm).Conclusions: CoQ10 has no significant effect on response to ovulation stimulation or on pregnancy rates.

Abstract Introduction This study was performed to compare the efficacy of marsupialization under nasal endoscopy versus Lacrimal probing in the treatment of congenital dacryocystocele. Methods Forty neonates (43 eyes) diagnosed with congenital dacryocystoceles were divided into Group A (nasal endoscopic marsupialization) and Group B (Lacrimal probing). The patients were followed up for 1 year after surgery. The efficacy, incidence of complications, and reoperation rate were compared between the two groups. Results The male:female ratio was 25:15 patients (27:16 eyes). In Group A, the success rate was 100%, the incidence of complications was 5%, and the reoperation rate was 0%. In Group B, the success rate was 90%, the incidence of complications was 20%, and the reoperation rate was 30%. Conclusion Compared with Lacrimal probing, marsupialization under nasal endoscopy provides greater efficacy and safety for congenital dacryocystoceles.

<p><strong>Background:</strong> To compare the results of endoscopic tympanoplasty with that of conventional tympanoplasty and to evaluate and compare the graft uptake in both of these methods. The study was done to evaluate the improvement in hearing after tympanoplasty and the problems faced while doing the endoscope assisted tympanoplasty.</p><p><strong>Methods: </strong>Between July 2010 to June 2013, 50 patients underwent tympanoplasty, 25 were endoscope assisted (group A) and 25 were microscope assisted (group B). Results of surgery were compared at the end of three and six months post operation.</p><p><strong>Results: </strong>The success rate in terms of graft uptake rate was 88% with endoscope assisted tympanoplasty and 84% with other microscope assisted tympanoplasty. Overall success rate was 86.0%. Mean hearing improvement was (16.24±10.21 dB) and (14.28±7.10 dB) in group A and group B respectively.</p><p><strong>Conclusions: </strong>Tympanoplasty with its visualization of hidden corners, justifies tympanoplasty by using endoscope in selected cases with comparable improved results in the literature. Furthermore, the cost of the endoscope is much less (about 10%) in comparision to operating microscope, making it more cost effective in developing countries. However, the endoscope cannot be employed in every case as one hand is blocked. In terms of Patient comfort, the endoscope assisted outnumbers the benefits of other conventional methods.<strong></strong></p>

Objectives: We compared the functional outcomes of fat myringoplasty and areolar tympanoplasty through a small postauricular incision in patients who underwent transcanal endoscopic ear surgery (TEES). Methods: The study included patients who underwent myringoplasty or type I tympanoplasty using TEES in our Department of Otolaryngology between April 2016 and May 2019. The patients were divided into 2 groups according to the type of graft material used, which was selected based on the available amount of subcutaneous fat and the surgeon’s experience. Results: In total, 63 patients received fat tissue grafts (group A) and 77 received areolar tissue grafts (group B). The median operative time was significantly longer in group B (132 minutes) than in group A (65 minutes); perforations were significantly larger in group B than in group A (61.0% vs 29.7% of the eardrum surface). The postoperative air conduction threshold, air–bone gap, and speech reception threshold values were significantly lower than the preoperative values in both groups. The graft success rate did not significantly differ between groups A (96.8%, 61/63) and B (96.1%, 74/77). In group A, the perforation was > 35% of the eardrum surface in 27.0% (17/63) of the patients; the graft success rate was 100% (17/17). In the remaining 46 patients (perforation > 35%), the graft success rate was 95.7% (44/46); this difference was not statistically significant. Conclusions: Transcanal endoscopic ear surgery increases the usefulness of fat myringoplasty for the repair of perforations > 35% of the eardrum surface. Postauricular fatty and areolar tissues are suitable for this simple and rapid technique, which yields excellent outcomes.

Introduction: The first line treatment for nasolacrimal duct obstruction (NLDO) is external dacrocystorhinostomy (DCR). Following DCR, patients are required to return to Tilganga Institute of Ophthalmology (TIO) six weeks postoperatively for the removal of a silicone stent. As the majority of patients travel large distances at significant cost to reach TIO, most often patients remain within Kathmandu during this six weeks interval. This places a large financial burden on patients. Methods: A randomized controlled trial was designed to compare patient outcomes after early (two weeks postoperatively) versus standard (six weeks postoperatively) removal of silicone stents. 50 selected patients were randomized into two equal groups. Results: At the time of publication, 31 patients (14 in group A and 17 in group B) had completed three months follow up. A success rate of 92.9% was noted in Group A and a success rate of 94.1% observed in group B. No significant difference was found between the two groups for success rate and rate of complications. Conclusion: Early tube removal post DCR appears to cause no significant difference in outcome or complication rates compared to standard tube removal.

Background: Treatment of granular myringitis (GM) is diverse with no definitive management. Objective: The aim of the present study was to see the effectiveness of different interventions for treating granular myringitis. Methodology: This was a single centred, parallel, randomized control trial. This study was done at the Specialized ENT Hospital of SAHIC, Dhaka from July 2010 to June 2012. Patients presenting with granular myringitis of 18 years of age or more with both sexes were included. All patients were divided into two groups by simple random sampling method of which patients of group A were treated by surgical treatment and that of group B were treated by medical treatment. Medical treatment was given in the form of topical ear drops and surgical treatment was performed by surgical debridement of granulation tissue followed by chemical cauterization. Repeated follow up was performed up to 6 months in both groups of treated patients. The primary outcome was the resolution of granulation tissue. During follow-up the secondary outcome variables were recurrence, perforation of the TM and any other complications or complain from the patients. Results: A total number of 60 patients were studied of which 30 patients were treated medically and 30 patients were treated surgically. The cure rate was higher in surgical treatment (80%) than conservative (16.7%) (p=0.011). The recurrence rate (17.24%) is also less in surgical group compared to medical treatment group (77.27%) (p=0.001). Conclusion: Surgical treatment is a more successful treatment modality for granular myringitis. Journal of National Institute of Neurosciences Bangladesh, 2019;5(1): 64-68

Background: In second trimester abortion, medical methods are preferred. Prostaglandins are the most widely used. Amongst them, misoprostol is the most commonly used. Thus, the study was conducted to delineate the effectiveness of simultaneous administration of mifepristone and misoprostol versus interval regimen mifepristone followed by misoprostol 12 hours apart in second trimester medical abortion.Methods: It was a prospective, single centered, comparative study conducted on 50 patients in Department of Obstetrics and Gynaecology, GMC, Amritsar coming for second trimester abortion, either elective or emergency, with gestational age between 12-20 weeks. Initially, 53 patients were enrolled in the study, 3 patients dropped out at different stages of study. Finally, 50 patients were enrolled and divided into two groups of 25 patients each by 1:1 randomization. In Group-A, mifepristone 200 mg orally along with misoprostol 600µg vaginally were given simultaneously, followed by 400 µg vaginal misoprostol every 4 hours for a maximum of five doses in 24 hours. Group-B initially received mifepristone 200 mg per oral followed by 12 hours later misoprostol 400µg vaginally and then 400µg vaginal misoprostol every 4 hours for a maximum of five doses in 24 hours. Primary outcome measure was effectiveness of regimen in complete abortion, which was confirmed on pelvic ultrasound 1-week after the last dose. Secondary outcome measure was to compare the induction abortion interval (IAI), dose of misoprostol required and adverse drug reaction (ADR) among both the regimens. P-value <0.05 was taken as statistically significant.Results: Mean age in Group-A was 25.68±3.79 years while in Group-B was 23.40±2.73 years. Both the regimens had success rate of 76% for complete abortion. However, IAI in Group-A was 5.9±4.47 hours whereas in Group-B was 9.6±5.07 hours, which was statistically significant (p= 0.009). A statistically significant difference was also observed in the mean dose of misoprostol between two groups that is, 1000±200µg and 1425±437.41µg respectively (p=0.01). Gestational age was related to IAI from 13 to 17.6 weeks in both groups (p=0.01) while no significant relation was seen between them in more than 17.6 weeks of gestation (p=0.63).Conclusions: Simultaneous administration of mifepristone and misoprostol showed better results than interval regimen in term of significant lesser induction abortion interval, lower dosages of misoprostol required with comparable success rates.

Background: The objective of this study is to assess the effectualness and safety of sublingual versus oral misoprostol following oral mifepristone for second trimester termination of pregnancy.Methods: This institution based contingent study was conducted on 220 women requesting for mid-trimester termination of pregnancy between 12-20 weeks with legal indication as per Govt. MTP act. After excluding the women as per exclusion criteria, they were randomly allocated into two groups (Group A Sublingual, Group B Oral), the women received 200 mg oral mifepristone followed by sublingual or oral misoprostol 400µg three hourly for a maximum of 5 doses 48 hours later. The course of misoprostol was reiterated if women failed to abort in 24 hours.Results: The mean induction-abortion interval of Group-A and Group -B was 4.02±1.39 hours and 6.44±1.79 hours respectively. The mean dose of misoprostol in Group–A and Group-B was 680±220.4µg and 1003.6±274.9µg. Hence mean Induction-abortion interval and dose were shortened in  Group-A as compare to Group-B (p <0.05). There was 100% success rate noticed via both routes. Evacuation was done in 4 (3.64%) women in Group-B as compare to only 1 (0.91%) in Group-A . The acceptability was significantly more in Group-B (100%) as compare Group-A (52.73%), probably because of unpleasant taste of sublingual misoprostol. All side effects (Nausea, pain, headache, and diarrhea) were common in both the Groups, only fever was significantly more common in sublingual group as compare to oral group (p<0.05).Conclusions: From present study authors conclude that, sublingual misoprostol when combined with mifepristone is effective for medical abortion in second trimester in terms of effectualness, endurability and success rate than oral route.
