Abstract
Background and Objectives: To investigate histopathological changes and serous carcinoma precursors such as secretory cell outgrowths (SCOUTs) and p53 signature in the bilateral tubal ligation (BTL) materials used during cesarean section (S/C). Materials and Methods: In total, 138 patients underwent S/C and tubal sterilization (TS) between October 2020 and May 2021 at Konya City Hospital. Patients' data were obtained from the hospital's system. All data and findings were investigated and statistically evaluated. Results: The mean age was 34.62 years (22-44), the mean gravity was 4.89 (2-15) and the mean parity was 3.46 (1-10). In total, 5.79% SCOUT, 7.24% atypia and 9.42% p53 signatures were observed. Significant correlations were shown between the epithelial cell lineage and age between Ki-67, SCOUT, and gravity; between the Ki-67 results and gravity and parity; and between the p53 score and age. Conclusions: TS is a common, safe, and effective method worldwide. Today, BTL is increasing along with increasing S/C ratios. In addition to the reduced risk of ovarian cancers with ligation alone, precursor lesions such as hyperplasia, SCOUT, p53 signature, and STIL/Serous tubal intraepithelial carcinoma (STIC) are encountered in the ampulla materials obtained. Considering the low rates of re-anastomosis, tubal excision may be recommended instead of ligation in women of relatively higher gravity and age.

Abstract
BACKGROUND Laminin-1 and matrix metalloproteinase (MMP)-9 may play roles in the progression from benign to malignant endometrium, so we aimed to investigate their levels of expression in these tissues. METHODS This case-control study was conducted at a tertiary care center between January 2014 and December 2016. Paraffin blocks of 50 specimens of benign endometrium with proliferative (n = 20), secretory (n = 11), and atrophic (n = 5) endometrium; simple endometrial hyperplasia without atypia (n = 12); and endometrial polyp (n = 2) histology and 49 specimens of malignant endometrium with endometrioid (n = 40), serous (n = 7), clear cell (n = 1), and undifferentiated (n = 1) types were immunostained with laminin-1 and MMP-9 antibodies and assessed for basement membrane continuity for laminin-1 and the percentage and intensity of MMP-9 expression in epithelial cytoplasm. RESULTS : Laminin-1 continuity in the basement membrane was higher in benign (92%) compared to malignant (16.3%) endometrium (p < 0.0001) without any difference between the subgroups within each group (p > 0.05). All atrophic endometria and endometrial polyps and 23.5% of low grade endometrioid and none of the other endometrial cancers showed uninterrupted basement membrane staining with laminin-1. All cases in malignant endometrium expressed MMP-9 with either low or high immunoreactivity while none of the cases in benign endometrium showed a high staining with MMP-9 (p < 0.01). Proliferative and hyperplastic endometrium together with grade 1 endometrioid cancer expressed MMP-9 better than the atrophic endometrium (p < 0.05). The immunoreactivity with MMP-9 increased gradually from secretory to hyperplastic endometrium and serous carcinoma (p < 0.05). MMP-9 expression in all types of cancers except grade 1 endometrioid and clear cell compared to proliferative endometrium was significantly higher (p < 0.05) and increased from proliferative to grade 2 endometrioid, grade 3 endometrioid, serous and undifferentiated endometrial carcinoma. DISCUSSION Gradual increments in MMP-9 expression and basement membrane laminin-1 discontinuity may indicate progression from normal to hyperplastic and to low- and high-grade cancerous endometrium.

Abstract
Background and Objectives This study aims to evaluate the capacity of wideband tympanometry (WBT) in predicting the prognosis of otitis media with effusion (OME). Subjects and Methods Sixty-one ears with effusion and 30 healthy ears of children were enrolled. The patients were followed up monthly using WBT. After the completion of measurements, the ears were separated into four groups according to the duration of recovery; Group 1: Good prognosis (≤1-month, n=18), Group 2: Worse prognosis (>1-month, n=29), Group 3: Surgical (no recovery, n=14), and Group 4: Control (healthy ears, n=30). Tympanometric peak pressure (TPP), resonance frequency (RF), and absorbance levels were compared within and between the groups. Results The TPP and RF values of the study group were lower than those of the controls (p<0.001). The ears with OME had lower absorbance measures than the controls at all frequencies; the differences were significant at 250, 500, and 1,000 Hz (p<0.001). However, at 2,000 Hz, the absorbance levels of the ears with OME were similar with those of the control group only in the good prognosis group (p>0.05). The receiver-operating characteristic analysis revealed that absorbance measures over 0.237 and 0.311 at 1,000 Hz and 2,000 Hz, respectively, have sensitivities and specificities over 70% for prediction of good prognosis, and the calculated odd ratio for these measures were 6 (p<0.05). Conclusions WBT measurement is promising in predicting the recovery of OME in children.

Abstract
AIMS Human asparaginase-like protein 1 (ASRGL1) is closely related to tumor growth. ASRGL1 can significantly promote cell proliferation and suppress apoptosis. To date, high levels of expression of ASRGL1 have been reported in various tumors, but the function of ASRGL1 in carcinogenesis is still not well understood. In this study, we aimed to immunohistochemically investigate the expression of ASRGL1 in non-neoplastic breast tissue and invasive ductal carcinoma. METHODS AND RESULTS ASRGL1 was evaluated immunohistochemically in 148 invasive ductal carcinomas and 105 nonneoplastic breast tissue samples to assess the impact on breast cancer development and its association with clinicopathologic features. ASRGL1 was observed positive in 63 (42.6%) and negative in 85 (57.4%) invasive ductal carcinoma. In nonneoplastic breast tissue, 24 (22.9%) cases were ASRGL1 positive and 81 (77.1%) were negative. A significant difference was observed between invasive ductal carcinoma and nonneoplastic breast tissue in terms of ASRGL1 expression, and ASRGL1 expression was increased in invasive ductal carcinoma (P = .001). Most estrogen receptor-negative tumors and progesterone receptor-negative tumors were also negative with ASRGL1 and the difference was significant (P = .006 and P = .001, respectively). The correlation between the ASRGL1 expression of the tumors and event-free survival or overall survival was not significant (P>.05). CONCLUSIONS ASRGL1 may play a role in increasing cell proliferation and breast cancer development. ASRGL-1 expression in breast cancer closely correlates with the hormone receptor status of the tumor. In breast cancer, ASRGL-1 expression does not contribute to predicting tumor behavior.

Abstract
Objective This study aimed to find out valuable parameters that predict the nature of breast papillary lesions before excision, and we compared our results with those in the literature. Materials and Methods We reviewed the medical records and pathology slides of patients diagnosed with papillary neoplasm after undergoing a core-needle biopsy between 2010 and 2020, who, subsequently, underwent surgical excision in a single tertiary care institution. The core biopsy results and pathology results of excision materials were compared with the radiological, pathological, and demographic findings. Results A total of 51 patients were included in the study. According to the excision results, the patients were divided into two groups: the atypical group, which included 20 patients (39.3%), and the benign group, which included 31 patients (61.7%). The results of the core biopsy showed that the loss of myoepithelial cell layer was identified in 18 patients in the atypical group, while it was present in all patients in the benign group. Tumor sizes were larger and patient ages were older in the atypical group compared with the benign group. No significant difference was found between atypical and benign groups in terms of breast imaging-reporting and data system (BI-RADS) classification and location (right vs left; central vs peripheral). The upgrade rate was between 0% and 16% in literature, while it was 4% in our study. Conclusion There is no consensus on whether patients diagnosed with papillary neoplasia as a result of core biopsy will undergo excision. According to our results, patients with following criteria should have their lesions excised: those who are advanced in age, those who are diagnosed with a papillary lesion as a result of core biopsies with loss of myoepithelial cell layer, and those who are diagnosed with large-sized lesions without loss of myoepithelial cell layer. Patients diagnosed with small-sized lesions without loss of myoepithelial cell layer and who are young in age are to be followed up without the need for lesion excision. The lesions should be adequately sampled.

Abstract
OBJECTIVE To evaluate ectopic adrenal cortical tissue (EACT) and identify clinical, pathological and radiological aspects. STUDY DESIGN Retrospective review of pathology reports in a single tertiary institution between 2010 and 2020 was conducted. Patients diagnosed with EACT were included for analysis. Demographic characteristics, accompanying pathologies and clinicopathological and radiological findings of these patients were analyzed. RESULTS There was a total of 17 patients in the cohort. Fifteen were boys and 2 were adults (1 male). The mean diameter of the EACT nodule was 0.25 cm (range 0.2-0.5 cm). All EACTs were incidentally diagnosed. Seven EACTs were diagnosed during an inguinal hernia repair, 6 during orchidopexy, 1 during partial orchiectomy, 2 during orchiectomy and 1 during hysterectomy and bilateral salpingoophorectomy due to uterine prolapse. DISCUSSION EACT is a rare entity that is mostly found incidentally during inguinoscrotal interventions. Radiological discrimination of EACT may not be easy and thus, not detected prior to surgery. Clinical significance of EACT is not very well understood, however it tends to be a benign pathology. Although it is more commonly found in children, adults may present with EACT, as well. CONCLUSION A tiny yellowish nodule detected in the inguinoscrotal region should be suspected for EACT by pediatric urologists, surgeons, and pathologists.

Abstract
Objective The aim of this study was to quantitatively and qualitatively analyze the abstracts presented at Turkish National Otorhinolaryngology Congresses in the years from 2009 to 2018. Methods Abstracts were defined and grouped according to their field of study, design, level of evidence, number of authors, the main institution in which they were held, and whether they were uni- or multi-centric. Frequency and percentage tables were prepared. Results In total, 5,463 studies, of which 1,431 (26.2%) were oral presentations and 4,032 (73.8%) were poster presentations were reviewed. The highest number of studies was in the field of otology and in the form of oral presentations (32%), and in the field of head and neck surgery in the form of poster presentations (37%). Fifty-seven percent of all studies were conducted in university hospitals, and 34% in Training and Research Hospitals. Eighty-three percent of oral presentations and 99% of poster presentations were clinical studies. The rate of experimental animal studies was 16% in oral presentations. The most commonly used design of orally presented clinical studies was descriptive (31%), whereas prospective randomized controlled design was the least common (3%). No study with a level 1 of evidence was found. The rate of oral papers presented with evidence levels 2, 3, 4, and 5 among all oral presentations were 22%, 13%, 11%, and 54%, respectively. Conclusion The findings indicated that the abstracts were satisfactory in quantity, but overall scientific quality was not sufficient. The data obtained may serve as a basis for future studies, and follow-up studies may guide individuals and institutions that steer the Turkish ENT community.

Abstract
Summary This study was aimed to reveal the prevalence of dog allergy and other common allergy and allergic symptoms in police dog trainers. Fifty-six police dog trainers and 150 workers as control group were included in this study. Medical records of dog trainers including respiratory, skin, eye symptoms and physical examinations and skin prick test results are compared with the medical records of control group. Positive SPT to dog was present in 21.4% of dog trainers, whereas the frequency of sensitization to dog in the control group was 1.3% (p minor 0.001). Dog allergy development risk is found 20 times greater in dog trainers than control group. In multiple logistic regression analysis, it was found that atopy was associated with dog allergy likelihood. Sensitization to dog allergens is an important occupational problem for dog trainers.

Abstract
INTRODUCTION Mucociliary clearance (MC) is a critical defense mechanism for the protection of the entire respiratory system. Nasal colonization of some pathogens and chronical nasal infections are important risk factors for peritonitis. Any disturbance in the MC causes stasis of secretions and secondary infections. OBJECTIVE The aim of the study was to evaluate the patients with chronic kidney disease (CKD) receiving continuous ambulatory peritoneal dialysis (CAPD) in terms of nasal MC. More specifically, the goal is to investigate the possible correlation between the nasal MC and peritonitis. METHODS Forty CAPD patients and 39 healthy volunteers were involved in the study. The nasal MC was evaluated with the saccharin test, in which a 1mm diameter saccharin particle was carefully placed on the antero-medial surface of inferior nasal concha. The time taken by the subjects from the placement of particle to the perception of the sweet taste was taken as mucociliary clearance time (MCT). The groups were compared in terms of MCT. The patient group was evaluated in terms of a peritonitis history, and the correlations with MC were analyzed. RESULTS Patient group with CKD consisted of 16 females and 24 males with a mean age of 32.4 years; healthy individuals in the control group consisted of 17 women and 22 men with a mean age of 33.3 years. There was not a significant difference in terms of mean MC time in patients with CKD when compared with the individuals in the control group. The comparison between the mean MCT in the patients who had a history of peritonitis and patients without peritonitis was statistically significant (p<0.05). CONCLUSIONS Unique for being conducted with patients in continuous ambulatory peritoneal dialysis, the current study shows that although the MC of CKD patients and healthy individuals is similar, patients with low rates of MC appear to present an increased incidence of peritoneal infection. Considering the small sample investigated, an invitation to future confirmatory studies would be appropriate.

Abstract
Background and Objectives Knowing the ototoxic potential of the agents used in medical treatments is important for the protection of hearing. Although we have knowledge regarding some effects of dexmedetomidine, which is an anesthetic-sparing drug, its influence over the hearing system has never been studied and is obscure yet. The aim of this study is to determine the effects of intravenous dexmedetomidine application during sevoflurane anesthesia on otoacoustic emissions (OAEs). Subjects and Methods This prospective randomized study was performed on 60 patients (34 male, 26 female, mean age: 30.6±9.2 years) who were scheduled for an elective surgery under general anesthesia and the patients were enrolled and randomly divided into 2 groups. They received dexmedetomidine (Group D) or Saline (Group S) infusion during a standardized Sevoflurane anesthesia. Transient and distortion product OAEs were measured preoperatively and postoperatively (24th hour). OAE results were compared within and between groups. Results In group D postoperative OAEs were lower than preoperative OAEs and postoperative levels of group S, especially at low frequencies (p<0.05). Conclusions Dexmedetomidine infusion affects the micromechanical function of cochlea especially in the low-frequency region. Dexmedetomidine should be carefully used during general anesthesia to avoid its probable harmful effects on cochlear micromechanics.

Abstract
Background/aim: To evaluate the diagnostic performance of strain elastography (SE) combined with B-mode ultrasound in distinguishing between idiopathic granulomatous mastitis (IGM) and malignant breast lesions. Materials and methods: Seventy-seven malignant breast lesions and 36 IGM were assessed using B-mode ultrasound and SE. Ultrasonographic findings for all the breast lesions were classified based on the 2013 American College of Radiology Breast Imaging Reporting and Data System (BI-RADS-US), and the SE findings were evaluated based on the strain ratio and a five-point scale. The diagnostic performances of B-mode ultrasonography, SE, and the combination of both methods were compared. Results: Significant differences in strain ratio and elastography scores were found between IGM and malignant breast lesions. When the lesions were assessed with B-mode ultrasound alone, in order to distinguish between IGM and malignant breast lesions, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 94.8%, 66.7%, 85.9%, 85.7%, and 85.8%, respectively. However, when assessed with a combination of B-mode ultrasonography and SE, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 96.1%, 100%, 100%, 92.3%, and 97.3%, respectively. Conclusion: The combination of SE and B-mode ultrasound has better diagnostic performance in the differentiation of IGM and malignant breast lesions than B-mode ultrasonography alone.

Abstract
BACKGROUND The aim of the study is to evaluate the long-term protective effect of N-acetylcysteine (NAC), an antioxidant agent, against aminoglycoside (AG)-induced ototoxicity. METHODS A total of 40 patients receiving continuous ambulatory peritoneal dialysis (CAPD) and having their first peritonitis attacks and planned to be treated with AGs were enrolled in the study. They were randomized into 2 groups: 1 group received additional NAC and the other did not. All patients underwent hearing tests with pure tone audiometry (PTA) after the diagnosis, at 1 month and 12 months and at the same time the tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels were measured. RESULTS Patients taking NAC had better hearing test results in both ears at 1 month except 2,000 Hz for the left ear, which wasn't significantly different between the 2 groups. Although patients taking NAC had generally better PTA results at 12 months, differences between the 2 groups were not statistically significant. Baseline IL-6 level was significantly higher in the NAC group than the control group. Both TNF-α and IL-6 levels at 1 month were significantly lower in the NAC group than in the control group. On the other hand, there was no significant difference between the 2 groups in terms of TNF-α and IL-6 levels at 12 months. CONCLUSIONS The results of the current study showed that NAC, a potent anti-inflamatory drug, may be otoprotective, but that the effect is not long-lasting.

Abstract
BACKGROUND Acute appendicitis (AA) is the most common reason for abdominal surgery in the world. The aim of this study was to evaluate the effect of medical treatment on histological findings in rabbits with AA. METHODS Twenty-one male New Zealand rabbits were divided into 3 groups: appendix ligation and medical treatment, appendix ligation and no treatment, and control group, which underwent only laparotomy. RESULTS In appendix ligation without treatment group, AA findings were much more severe. CONCLUSION Medical treatment reduced inflammation of AA.

Abstract
Objectives To identify the optimal pharmacological method of preparing patients for nasal endoscopy. Methods Twenty healthy volunteers were enrolled in this prospective, randomized, double-blind study. Four types of medications were applied in their nostrils with binary combinations of spray bottles on four different days in a random order: placebo (normal saline [NS]+NS), decongestant (NS+oxymetazoline), anesthetic (NS+lidocaine), and decongestant plus anesthetic (oxymetazoline+lidocaine). Rigid nasal endoscopy was performed 10 minutes after spray application. The volunteers evaluated the discomfort caused by each spray application, and nasal pain scores due to the passage of the endoscope. The physicians quantified nasal decongestion using a visual analogue scale. Endoscopy duration as well as pulse and mean blood pressure (MBP) before spray application, 10 minutes after the application, and immediately after endoscopic examination were also recorded. Results The discomfort caused by lidocaine was significantly higher than that caused by the other sprays (P<0.001). The lowest pain score related to endoscopy was obtained for oxymetazoline+lidocaine (P<0.001). Nasal decongestion was best achieved with NS+oxymetazoline (P<0.001). Endoscopy duration was the shortest for oxymetazoline+ lidocaine (P<0.05). Statistically significant MBP changes were only seen with the application of NS+oxymetazoline (P<0.05). However, neither MBP nor pulse rate change was significant clinically. Conclusion Application of decongestant and anesthetic sprays together seems to be the best method of pharmacological preparation of patients for nasal endoscopy.
