Aim: To determine the efficacy of Titanium versus Teflon piston on hearing outcome in terms of Air Conduction Threshold (ACT) gain and Air Bone Gap (ABG) closure in patients undergoing LASER Stapedotomy. Methods: This retrospective study was conducted at the department of ENT and Head and Neck Surgery, AIIMS Patna. 40 patients underwent LASER stapedotomy. Both Teflon (0.4mm and 0.6mm D, Grace Medical Devices) and Titanium (0.4mm D, Kurz Medical Devices) pistons were inserted randomly. Crimping of titanium Kurz piston was not required due to its unique design which fits on to the incus long process like a clip whereas all the Teflon pistons required crimping.Titanium (Kurz Medical Devices) pistons are costlier in comparison to Teflon (Grace Medical Devices) pistons. Preoperative and 3 monthly postoperative Pure Tone Audiograms (PTA) wereobtained. ACT (Air conduction threshold) gain and ABG (Air Bone Gap) closure were measured.Data was analyzed with IBM SPSS Statistics software Version 20. Descriptive analysis,paired and unpaired t-tests were applied. P-value of <0.05 at 95% confidence levels was considered statistically significant. Results: 40 patients (M: F: 3:7) underwent LASER stapedotomy.Titanium piston was utilized in 11and Teflon in 29 patients. Patients with titanium piston experienced a mean ACT gain of 21.51±05.42dBand mean ABG closure of 12.27±05.18 dB. Those with Teflon piston gained a meanACT gain of 18.54±04.43 dB and mean ABG closure of11.96±06.12 dB.Both groups experienced statistically significant hearing gain (p <0.05).Both groups were however comparable and the difference between these parameters was statistically insignificant (p>0.05).Conclusion: Both titanium and Teflon pistons are equally efficacious in improving postoperative hearing gain in LASER stapedotomy patients in terms of ACT gain and ABG closure. Titanium Kurz pistons do not require crimping making it easier to use in comparison to the Teflon pistons which needs to be crimped every time though cost may be a limiting factor in the usage of Titanium pistons.Both types of pistons can be satisfactorily employed in this surgical procedure if we consider the hearing gain post operatively.

<p class="abstract"><strong>Background:</strong> Otosclerosis presents as conductive hearing loss, stapedotomy is the treatment for otosclerosis, and different sizes of piston diameter are available for the procedure. Aims and objectives were to study and compare hearing improvement between the 0.4 and 0.6 mm sizes of teflon piston in stapedotomy.</p><p class="abstract"><strong>Methods:</strong> It was a prospective randomized controlled trial. Patients fulfilling inclusion criteria were subjected for small fenestra stapedotomy. Patients were divided into two groups after randomization into group A (with 0.4 mm piston diameter) and group B (with 0.6 mm piston diameter). The hearing outcome with standard audiological assessment was performed at one month and six months postoperatively.  </p><p class="abstract"><strong>Results:</strong> Comparison of 1 month AB gap among the patients with 0.4 mm piston and 0.6 mm piston showed that there was no statistically significant difference among both the groups of patients (independent t test p value=0.699). Comparison of 6 month AB gap among the patients with 0.4 mm piston and 0.6 mm piston showed that there was no statistically significant difference among both the groups of patients (independent t test p value=0.54).</p><p class="abstract"><strong>Conclusions:</strong> There was no significant difference in hearing improvement among the individual methods (piston size 0.4 and 0.6) with each other both in 1 month post-operative and 6 month post-operative follow up.

Objective: The aim of this study was to evaluate hearing outcome after stapedotomy in patients with Otosclerosis. Methods: This cross sectional study was carried out from July 2017 to January 2019 in National Institute of ENT, Unit V. About 22 patients with Otosclerosis were included in this study. Diagnosis of Otosclerosis was based on the history, medical status with Otoscopy, Tuning fork tests and Audiometric tests. We compiled data on the pre and post operative air-bone gap (ABG) at 0.5, 1, 2 KHZ. The ABG was Calculated using AC and BC thresholds on the same audiogram. Post operative hearing gain was then Calculated from the ABG before the operation minus the ABG of the last follow up examination Results: In this study most of the cases were age group 14-30 years (72.7%), female (54.5%). Most common symptoms was progressive hearing loss, tinnitus (77.8%).The average preoperative hearing loss in this study was (AC) was 48.31±7.68. The average post opt. hearing (AC) at follow up was 28.95±10.30 with an average hearing gain of 15.40±8.53 dB which was significant. The average pre-operative ABG was 28.99 dB ± 8.10. The average post opt. ABG was analyzed at 1 follow up showed ABG 13.18±8.09 dB which was found to be significant. Conclusion: Stapedotomy is an effective surgical procedure for the treatment of otosclerosis which leads to improvement in patient’s quality of life. A favorable hearing outcome can be obtained by the combination of experienced hands with minimal surgical trauma and appropriate surgical technique.

ABSTRACT:Anti-dumping on tinplate products aim to protect domestic industries. Still, some industries want tinplate products not to be subject to anti-dumping because domestic production is not sufficient. This research examines the application of anti-dumping import duties on tinplate products from China, Taiwan, and Korea from 2014 to 2018, to know whether there are differences in the value of imports before and during the anti-dumping import duty. Use secondary data sourced from UN-Comtrade. Samples are selected by countries that have continuously sent tinplate products to Indonesia from 2010 to 2018, namely China, Taiwan, Korea, Japan, Germany, India, and Malaysia. Using the Mean Equality Test, it is known that there are differences in the import value before and during the anti-dumping import duty, with a p-value of 0.0114 less than α (0.05), so it is concluded that there is a difference in the import value of the tinplate product before and during anti-dumping duty. Descriptive analysis results illustrate imports from China and Taiwan tend to decrease. In contrast, imports from Korea tend to increase despite being subjected to anti-dumping duties because they can compete by using preferential tariffs based on free trade schemes.Keywords: Antidumping, Import duty, TinplateABSTRAK:Anti-dumping terhadap produk tinplate bertujuan melindungi industri dalam negeri, akan tetapi terdapat ìndustri yang menginginkan produk tinplate tidak dikenakan anti-dumping karena produksi dalam negeri belum mencukupi. Penelitian ini menguji penerapan bea masuk anti-dumping terhadap produk tinplate dari China, Taiwan dan Korea selama tahun 2014 s.d. 2018, dengan tujuan mengetahui apakah ada perbedaan nilai importasi sebelum dan selama dikenakan bea masuk anti-dumping. Menggunakan data sekunder yang bersumber dari UNComtrade. Sampel dipilih negara yang secara kontinyu mengirim produk tinplate ke Indonesia sejak 2010 s.d. 2018, yaitu China, Taiwan, Korea, Jepang, Jerman, India dan Malaysia. Menggunakan Mean Equality Test, diketahui terdapat perbedaan nilai importasi sebelum dengan selama dikenakan bea masuk anti-dumping. Hasil penelitian menunjukkan bahwa nilai-P (p-value) adalah 0,0114 lebih kecil dari alpha (α=0,05), sehingga disimpulkan terdapat perbedaan pada nilai importasi produk tinplate sebelum dengan selama dikenakan bea masuk anti-dumping. Hasil analisis deskriptif menggambarkan importasi dari China dan Taiwan cenderung menurun sedangkan importasi dari Korea cenderung naik walaupun dikenakan bea masuk anti-dumping karena mampu bersaing dengan menggunakan tarif preferensi berdasarkan skema perdagangan bebas.Kata Kunci: Anti-dumping, Bea Masuk, tinplate

Medication-related osteonecrosis of the jaw (MRONJ) is a severe side effect of antiresorptive medication. The aim of this study was to evaluate the incidence of denosumab-related osteonecrosis of the jaw and to compare the clinical and radiological extent of osteonecrosis. A retrospective study of patients who received Xgeva® at the Institut de Cancérologie de Lorraine (ICL) was performed. Patients for whom clinical and radiological (CBCT) data were available were divided into two groups: “exposed” for patients with bone exposure and “fistula” when only a fistula through which the bone could be probed was observed. The difference between clinical and radiological extent was assessed. The p-value was set at 0.05, and a total of 246 patients were included. The cumulative incidence of osteonecrosis was 0.9% at 6 months, 7% at 12 months, and 15% from 24 months. The clinical extent of MRONJ was significantly less than their radiological extent: in the “exposed” group, 17 areas (45%) were less extensive clinically than radiologically (p < 0.001) and respectively 6 (67%) for the “fistula” group (p < 0.031). It would seem that a CBCT is essential to know the real extent of MRONJ. Thus, it would seem interesting to systematically perform a CBCT during the diagnosis of MRONJ, exploring the entire affected dental arch.

The study was conducted to know the occurrence of myiasis in cattle and goats at Babuganj Upazilla Veterinary Hospital, Barisal, Bangladesh. A total of 160 animals were examined. Among them 46 animals were found to be myiasis infested. A structured questionnaire was used to collect data on species, breed, age, sex, body condition of the animal, onset and duration of illness, affected sites of myiasis. The study was conducted during March 2014 to May 2015. All the data that were collected were entered into MS excel. Descriptive analysis was done by column and pie charts. It was possible to follow the response of treatment using two treatment protocols. The overall occurrence of myiasis was 28.75% where 39.13% in cattle and 60.87% in goat. The occurrence was higher in cross breed cattle (55.56%) than the local (44.44%). Similarly the occurrence rate was higher in cross breed goat (42.86%) than local breed (28.57%). Less than 6 months aged animals (71.73%) and females (cattle-61.11% and goat-64.29%) were more prone to myiasis. The frequency of maggot infestation was higher in navel region (54.35%) followed by vaginal (28.26%) and rectal (10.87%) regions respectively. The percentage of recovery to Inj. SP vet, Inj. Asta vet and Inj. Vermic were 67.86%. Myiasis is the major problem in livestock production in our country. Animals at high risk should be managed properly to avoid wound and special attention on wound management should be given after castration and parturition to prevent myiasis.Res. Agric., Livest.

BACKGROUND: This is a retrospective study of 60 cases, to detect the expression of ER, PR, HER2neu, CK5/6 and Ki67 proliferation index in breast carcinomas by immunohistochemical method and to determine the newer molecular classication. Few patients have recurrence inspite of being diagnosed under the category of low risk and few do well in the high risk group which can be attributed to the molecular level differentiation. AIM: The aim of this study is to categorize the patients under molecular classication, and to compare the clinicopathological parameters with it and to denote the signicance of targeted therapy. MATERIALS AND METHODS: A retrospective study of detecting the expression of the above said markers in modied radical mastectomy specimens received at a tertiary care centre during the period from January 2015 to June 2018. A total of 60 cases which included 30 of IDC NST and 30 cases of special variants were selected for immunohistochemical analysis. RESULTS: Out of the 60 cases studied, the most common was found to be the luminal A type comprising 37% and the least common was the luminal B and hybrid types each comprising 8%. The most common grade for HER2 was Grade III (50%). The association of histological grade with the molecular classication was statistically signicant with the p value of 0.01. Basal type (56%) had the highest incidence of N3 stage. ER, PR, HER2 neu, CK5/6 expression and proliferation index with Ki67 had a statistically signicant association with the molecular classication. High proliferation index (>14%) with Ki67 was noted in Luminal B, Basal and Hybrid types. 78% of the total 60 cases were alive and healthy. One death was reported in HER2, Hybrid and Basal types. The negative kappa value obtained while studying the agreement between the histopathological and molecular classication, indicates that the agreement is worse than chance and hence the importance of molecular classication is substantiated for the targeted therapy.
