Background: Otosclerosis is one of the commonest diseases of the ear mostly involves the otic capsule. Most often otosclerotic foci appear in stapes region leading to stapes fixation, predominantly affect the adolescence female. The most common presenting symptom of clinical otosclerosis is conductive deafness. The mainstay of treatment for otosclerosis is surgery. Surgical options include stapedectomy, stapedotomy with or without stapedial tendon preservation. The latter being is the procedure of choice. Aim: The aim of this study is to compare the outcome of uncomfortable loudness level in stapedotomy with or without stapedial tendon preservation. Methods: A prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka for 18 months in patients with otosclerosis. Total 30 subjects were selected based on the inclusion and exclusion criteria. All patients were assessed pre-operatively by clinical examination, otoscopy and microscopic examination. Hearing was assessed by pure tone audiometry. Uncomfortable level and stapedial reflex threshold were tested in all cases. The selected cases were placed into two groups. Stapedial tendon resection in Group-I and stapedial tendon preservation in Group-II. Post-operative follow up was done at 3 months and 6 months. Hearing and uncomfortable loudness level were evaluated with PTA during follow up by calculating the average of 500Hz, 1000Hz, 2000Hz and 4000HZ. The data were calculated manually. The statistical significance was set to P< 0.05. Results of the study were expressed as mean, standard deviation (± SD), frequency and percentages. Means and standard deviations were reported for continuous variables. Frequencies and percentages were reported for categorical variables. Unpaired Student’s t test was done to compare the continuous variables and Chi Square test was done to compare the categorical variables. Results: In this study preoperative average ABG for group I and group II were 35 ± 4.57 dB and 34 ± 4.17 dB respectively. In group I, post operative average ABG after 3 months and 6 months were 14 ± 3.7 dB and 13±3.3 dB respectively. Post operative average ABG after 3 months was 13 ± 5.7 dB and was 12 ± 4.4 dB for group II. But the hearing improvement between two groups was not statistically significant. In case of preoperative mean UCL was 95 ± 1.8 dB and 96 ± 2.5 dB for group I and group II respectively. Postoperative mean UCL after 3 months was 96 ± 3.57 dB and after 6 months was 99 ± 6.28 dB in group I. For group II, postoperative mean UCL after 3 months and 6 months was 107±4.2 dB and 113 ± 3.2 dB respectively. Here mean UCL was on average 11 dB higher for group II in 3 months and additional 6 dB improvement noted after 6 months, but show minimal change in group I. This finding was statistically significant. Conclusion: Preservation of the stapedial tendon is the choice in the surgical treatment of otosclerosis which helps to improve functional outcomes as well as to provide the more physiologic protection of middle ear. Postoperative discomfort threshold levels were increased in patients who had their stapedial tendon restored. Bangladesh J Otorhinolaryngol 2021; 27(2): 117-123

ABSTRACT Introduction: Plastic surgery in India is in an era of transition. The speciality faces many challenges as it grows. The present study attempts to identify these challenges and the prevalent mood among the teachers and the trainees. Materials and Methods: The study was conducted from September 2011 to June 2012. In an E-mail based survey a questionnaire was mailed to professionals actively involved in teaching and training of residents in plastic surgery in many institutes running MCh courses in plastic surgery (Group I) [Appendix 1]. Another questionnaire was mailed to residents undergoing training in plastic surgery and those who had completed their training within past 2 years (Group II) [Appendix 2]. Chi-square test was applied to test for statistical significance. Observations: 29 Group I and 33 Group II subjects responded to the questionnaire. While 72.4% teachers believed that the current system is producing plastic surgeons with enough skill level, only 9.1% of the respondents in Group II thought the same (Chi-square = 28.1; df = 2; P < 0.001). Whereas 58.6% Group I respondents thought that their student is sufficiently equipped to compete in today’s scenario [Figure 1], only 18.2% Group II respondents thought that their training is enough [Figure 2]. (Chi-square = 16.4; df = 2; P < 0.001). Nearly 28% respondents in Group I and only 3% in Group II thought that scientific research and publications should be made mandatory for successful completion of plastic surgery training (Chi-square = 9.4; df = 2; P = 0.009). Adequate exposure was thought to be available in general plastic surgery (Group I: 92% Group II: 81%), maxillofacial surgery (Group I: 72% Group II: 68%) and hand surgery (Group I: 84% Group II: 69%). Both groups agreed that exposure is lacking in craniofacial surgery, aesthetic surgery and microvascular surgery. Aesthetic surgery (38.7%) and microvascular surgery (32.6%) were the most frequent response when the Group II respondents were enquired about the subspeciality they would like to focus on in their practice. Inter-departmental exchange of students for limited period of time was favoured by 86.2% of Group I respondents and 93.9% Group II respondents (Chi-square = 1.3; df = 2; P = 0.49). Conclusion: The current training programme is differently perceived by teachers and the trainees. We recommend that constant deliberations at national and regional forums should take place regarding our education and training programmes.

BACKGROUND: A congenital lung malformation (CLM) that is diagnosed on prenatal ultrasound exam may subsequently become undetectable on later scans, a “vanishing” CLM. OBJECTIVE: The purpose of our study is to characterize the prenatal natural history and postnatal outcomes of “vanishing” lesions treated at our institution. METHODS: We performed a retrospective chart review of 107 patients diagnosed prenatally with CLM at our institution. Comparisons were made using Kruskal-Wallis or t-test for continuous variables and Fisher’s exact test or Chi-Square test for categorical variables. Multivariable analysis using logistic regression was performed. RESULTS: Of the 104 patients, 59 (56.7%) had lesions that became sonographically undetectable on serial ultrasound scans. Patients with lesions that vanished prenatally tended to need less Neonatal Intensive Care Unit (NICU) admission at birth (persistent CLM: 54.8%vs vanished CLM: 28.8%), decreased need for supplemental O2 at birth (persistent CLM: 31.0%vs vanished CLM: 11.9%), and decreased delay in feeds (persistent CLM: 26.2%vs vanished CLM: 8.5%) compared to those with persistent CLM. After multivariate analysis controlling for maternal steroid administration and sex, admission to NICU maintained a slight statistical significance, with patients in the vanishing CLM group 2.5 times less likely to be admitted to the NICU. None of our patients whose lesions vanished prenatally required mechanical ventilation. Eighty-six patients underwent postnatal computed tomography (CT) chest. Only 2 patients had lesions that regressed on postnatal CT. CONCLUSION: Lesions that vanish on prenatal imaging may be associated with improved clinical outcomes. The rate of true regression at our institution was as low as 2.3%.

AbstractObjectiveTo reduce prevalence of anaemia in low-income postpartum women.DesignA randomised, non-blind clinical trial was conducted among 959 low-income, postpartum women in eleven clinics in Mississippi. The clinics were randomised to one of three treatment groups: (i) selective anaemia screening of high-risk women as recommended currently (control); (ii) universal anaemia screening and treatment of anaemic women (group I); and (iii) universal Fe supplementation of 65 mg/d for two months to all low-income women (group II). All study participants within each clinic received the same treatment. Women were followed up at 6 months after delivery. Hb was measured at baseline and at follow-up. The primary outcome variable was the proportion of women with anaemia after treatment.SettingEleven health clinics in Mississippi.SubjectsLow-income, postpartum women.ResultsBaseline characteristics of the three study groups were compared using one-way ANOVA and an appropriate post hoc test for continuous variables and the χ2 test for categorical variables. Fifty-two per cent of postpartum women were anaemic (Hb < 12·0 g/dl) and the rate decreased to 33 % at 6 months after the intervention. Group II women, who received universal Fe supplementation, improved their Hb status significantly (P < 0·001) at 6 months postpartum compared with the other groups. Prevalence of anaemia was also significantly lower among group II women (22·5 %) compared with controls (34 %) and group I women (43 %; P < 0·001).ConclusionsA universal Fe supplementation strategy was effective in reducing the prevalence of anaemia among low-income postpartum women.

Abstract Background Cardiogenic shock (CS) is a lethal complication. Given the poor outcome of CS, we performed a retrospective cohort study to identify whether the neutrophil-to-albumin ratio (NAR) was significantly associated with mortality from CS. Methods All patient data were extracted from the MIMIC III version 1.3. Comparisons between groups was made using the chi-square or Fisher’s exact tests for categorical variables and the variance analysis or the Kruskal-Wallis test was used for continuous variables. The primary outcome was 30-day mortality and the secondary ones were 90-day and 365-day mortality. We used Cox proportional hazards models to evaluate the association between the various categories of NAR and survival. To further identify the association, subgroup analyses were performed. Results A total of 475 patients with CS were enrolled. A significant positive correlation between NAR levels and 30-day, 90-day or 365-day mortality was observed. For the primary outcome of 30-day mortality, the HR (95% CI) values given NAR levels 23.54–27.86 and > 27.86 were 1.72 (1.17, 2.53) and 1.96 (1.34, 2.87) compared with the reference (NAR < 23.47) in tertile analysis. In multivariate analyses, the HR (95% CI) values were still of statistical significance[1.98 (1.25, 3.15) and 2.03 (1.26, 3.26)]. When quintiles were applied to grouping patients according to NAR level, similar associations were also observed. For the secondary outcomes, the upward trend remained statistically significant. Conclusions NAR level was associated with survival from CS. NAR appeared to be an independent and readily-available prognostic biomarker of mortality in patients with CS.

Background: Warfarin anticoagulation presents a common barrier to undergoing cardiac catheterization procedures. Using radial access and other bleeding mitigation strategies, it is not known if elevated INR truly portends an increased risk of adverse events. We sought to understand the relationship between in hospital mortality and bleeding with INR in patients undergoing coronary interventional catheterization procedures. Methods: The prospectively-collected Dartmouth Dynamic Registry was queried for all patients who underwent catheterization with coronary intervention from 2014 to 2018. Of the 5015 patients identified, 2120 patients had a recorded INR value within 24 hours of the procedure. Demographics, procedural variables, and in hospital outcomes were collected. Patients were divided into two groups: INR &lt1.8 and INR &gt1.8. Incidence of bleeding (access site hematoma &gt5cm, post procedure blood transfusion) as well as in-hospital mortality were queried for each group. Stata was used to determine statistical significance, using chi-square analysis for categorical variables and standard t-test for continuous variables. Results: Of the 2120 patients with INR values, 1968 patients were identified with INR &lt1.8 (median INR 1.1; range 0.7-1.7) and 152 patients with INR &gt1.8 (median INR 2.2; range 1.8-11.1). Patients with elevated INRs had higher acuity (urgent or emergent cases) and were older. Other baseline and procedural characteristics were similar. Outcomes between those with elevated INR and those with lower INR values were similar, including access site injury, hematoma, and need for transfusion (Table I). Overall mortality did not differ between the two groups. Conclusion: When compared to patients with INR &lt1.8, patients with INR &gt1.8 are more likely to undergo coronary intervention on an urgent or emergent basis. Despite this, there is no difference in bleeding, need for transfusion, or overall in-hospital mortality.

Purpose: To evaluate the outcomes of implanting intrastromal corneal ring segment (ICRS) using two different strategies in a specific paracentral keratoconus phenotype. Methods: Eighty-nine eyes with paracentral keratoconus with perpendicular topographic astigmatism and comatic axes were evaluated before and after implanting a 150° arc-length ICRS. Patients were divided into two groups according to the axis where the ICRS was implanted: Group I: comatic axis and Group II: flat topographic axis. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refractive errors, and root mean square (RMS) for coma-like aberration were recorded. The postoperative follow-up was 1 year. Results: Mean UDVA (logMAR) changed from 0.49 ± 0.37 preoperatively to 0.30 ± 0.32 6 months afterwards ( p < 0.001) in the group I and from 0.53 ± 0.34 to 0.37 ± 0.35 ( p < 0.001), in the group II. Mean CDVA in group I changed from 0.11 ± 0.18 preoperatively to 0.06 ± 0.14 6 months after surgery ( p < 0.001). In group II the improvement did not reach statistical significance (from 0.09 ± 0.10 to 0.07 ± 0.09; p = 0.06). No eyes lost lines of CDVA in group I. Eight eyes (15.7%) lost lines of CDVA in group II. The spherical equivalent decreased after surgery in both groups ( p < 0.001). The RMS for corneal coma-like aberration only decreased in the group I ( p < 0.001). Conclusion: Both strategies provided safe and effective visual and refractive outcomes in the specific keratoconus phenotype analyzed. The orthopedic strategy provided better visual outcomes than the refractive one.

Abstract Background Double J ureteral stents are widely used on urological patients to provide drainage of the upper urinary tract. Unfourtunately, ureteral stents are not free from complications, as bacterial colonization and require a second procedure for removal. The purpose of the current comparative experimental study is to evaluate a new heparin-coated biodegradable antireflux ureteral stent (BraidStent®-H) to prevent urinary bacterial colonization. Methods A total of 24 female pigs were underwent determination of bacteriuria and nephrosonographic, endoscopic and contrast fluoroscopy assessment of the urinary tract. Afterward, were randomly assigned animals to Group-I, in which a 5Fr double-pigtail ureteral stent was placed for 6 weeks, or Group-II, in which a BraidStent®-H was placed. Follow-up assessments were performed at 1, 3, 6, 8, 12 weeks. The final follow-up includes the above methods and an exhaustive pathological study of the urinary tract was accomplished after 20 weeks. Results Bacteriuria findings in the first 48 h were significant between groups at 6 h and 12 h. Asymptomatic bacteriuria does not reach 100% of the animals in Group-II until 48 h versus Group-I where it appears at 6 h. The weekly bacteriuria mean rate was 27.7% and 44.4% in Group I and II respectively, without statistical significance. In Group II there were no animals with vesicoureteral reflux, with statistical significance at 3 and 6 weeks with Group-I. The 91.2% of stents in Group-II were degraded between 3 and 6 weeks, without obstructive fragments. Distal ureteral peristalsis was maintained in 66.6–75% in Group-II at 1–6 weeks. Conclusions The heparin coating of BraidStent® allows an early decrease of bacterial colonization, but its effectiveness is low at the long term. Heparin coating did not affect scheduled degradation rate or size of stents fragments. BraidStent®-H avoids the side effects associated with current ureteral stents, thus should cause less discomfort to patients.

Objective: To determine whether concomitant use of vitamins B1, B6, B12 along with low dose of diclofenac sodium causesquicker pain relief in patients of acute lumbago compared with diclofenac sodium alone. Design: A randomized clinical trial. Setting: SurgicalDepartment of C M H Attock. Period: From September 2004 to August 2005 Patients & Methods: A total of 50 patients were selected forthe study. The patients complaints were of acute lumbago of less than 3 days duration with severe impairments of movements. The age groupof patients was between 20 and 65 years. The patients were randomly assigned into two groups. Group I was prescribed tablet diclofenacsodium 25mg along with vitamin B-complex containing combination of 100mg thiamine nitrate (B1), 100mg pyridoxine hydrochloride (B6), and200mcg cyanocobalmine (B12) three times a day. Group II patients were prescribed 25mg of tablet diclofenac sodium alone. Improvement inthe intensity of pain at rest and during movements (as assessed by the patients) was noted in accordance to visual analogue scale 1 to 10.The effectiveness of diclofenac sodium in combination with vitamin-B complex with diclofenac sodium alone was judged on the basis of extentof pain relief after 7 days of treatment. Results: A total of 25 patients were treated with combination of diclofenac sodium & vitamin-B complex(Group I) and 25 were treated with diclofenac sodium alone (Group II). As far as the extent of pain relief in first 7 days is considered, 22 patients(88%) belonging to group I and 10 patients (12%) belonging to group II had an excellent pain relief and were able to carry on with their normalroutine activities. Remaining 3 patients in group I were completely relieved of pain in next 3 days while 15 patients in group II had to completeanother 10 days for complete cure. To test the statistical significance of the result chi-square test was applied and the result showed thatpatients of Group I responded significantly well to the treatment as compared to those in Group II. Conclusion: Using the parameters of painrelief and movements of vertebral column, the combination of diclofenac sodium & vitamin-B complex was found to be more effective modeof treatment as the duration of treatment and the dosage of diclofenac sodium was less and also relief of pain was more rapid.

3 Background: Contralateral breast cancer (CBC) risk in BRCA1 & 2 mutations is up to 64%. Patients (pts) with estrogen receptor positive (ER+) breast cancer (BC) are offered tamoxifen (TAM) or Aromase inhibitors (AI) adjuvantly. Reports suggest that TAM may reduce the risk of CBC in BRCA mutation; however there is no such data on the effect of AIs. Here, we evaluate the effect of TAM and AI as potential CBC risk reducers in a cohort of women with known BRCA status. Methods: 1043 BC pts receiving genetic counseling and BRCA testing were included. 13 had metastasis, 168 had a variant BRCA, and 50 had synchronous BC, and were excluded. Of the 812 remaining pts, 153 had a deleterious BRCA 1 or 2 mutations. Pts were followed from the diagnosis of BC until CBC, death, or last follow-up. The study had IRB approval. Univariate analyses were performed to test the significance of each variable in relation to BRCA status using chi-square tests for categorical variables and t tests for continuous variables. Results: The median age at diagnosis of BC was 42.3 years (range: 21-84). Median follow up was 8.6 years. 86% (700) had ER+ tumors, 80% were diagnosed with T1-2, and 81% had N0-N1. 76% (622) received TAM, and 37% (304) received AI. A total of 68 (8.7%) CBCs occurred of which 14% (21/153) occurred in BRCA carriers vs 7% (47/659) in BRCA non-carriers. Multivariate analyses indicated that BRCA status and AI use were significantly associated with CBC. Specifically, compared with BRCA negative, pts with BRCA1+ or BRCA2+ had larger hazard of developing CBC, Hazard Ratio (HR) (95% confidence interval (CI)) = 2.49 (1.21, 5.10), p = 0.013 for BRCA1+ vs Negative. HR (95%CI) = 1.97 (1.05, 3.73), p = 0.036 for BRCA2+ vs Negative. Compared to pts who did not receive AI, those who received AI had smaller hazard of developing CBC, HR (95%CI) = 0.42 (0.22, 0.81), p = 0.01. The interaction between AI and BRCA status was not significant (p = 0.4), hence all pts benefited from AI use in terms of CBC risk reduction. TAM use did not show significant effect on the risk of CBC in univariate and multivariate analyses (p > 0.13). Conclusions: This is the first report showing that AIs can reduce risk of CBC in women with BC who have a BRCA mutation. This finding should be validated in larger independent cohorts.

Objective: To determine the contribution of otoendoscopy in the surgical management of atelectatic ear to improve clinical and audiological results. Methods and Materials: Thirty eight ears in 24 patients with middle ear atelectasis and intact ossicular chain were randomly assigned into 2 groups: Group I included 27 ears who were underwent endoscopic T- tube insertion and Group II included 11ears who were underwent endoscopic cartilage tympanoplasty. Assessment of hearing was performed for all cases preoperatively, 3 months postoperatively. Statistical analysis used: The analysis of the data was carried out using the IBM SPSS 20.0 statistical package software. Data were expressed as mean and standard deviation for quantitative measures in addition to both number and percentage for categorized data. Chi-square test or Fisher’s exact test were used to compare categorical variables. A P-value less than 0.05 was considered to be statistically significant. Results: There is significant postoperative improvement of ABG averages reported in the two studied groups with mean hearing gain of 21.67±7.97dB in group I and 19.72±5.3 dB in group II. Conclusion: At three months, there was significant statistical difference concerning different audiological parameters among the two groups.
