Abstract
OBJECTIVE This study evaluated the effect of brochure-based and video-assisted information provided before spirometry on patient compliance. PATIENTS AND METHODS This was a randomized controlled clinical trial. Before the test, subjects in intervention groups were shown a leaflet outlining the steps of the spirometry protocol and a video prepared for the same purposes. The control group was given standard routine information by the technician before spirometry. RESULTS The study included 450 patients. We found a significant correlation between compliance status and age, female sex, being a non-smoker, having no known lung disease, investigating respiratory disease as an indication for spirometry, having first-time spirometry, and receiving pre-test information via leaflets. Variables of age, sex, smoking, indication for spirometry, diagnosis, and previous spirometry, which were found in multivariate analysis to be associated with 'compliance with the test protocol' were further processed using regression analysis which identified 'previous spirometry' as the most decisive variable affecting 'compliance with the test protocol'. CONCLUSIONS Providing information via brochure-based and video-supported information did not contribute to compliance with the testing protocol, leading us to the conclusion that such informative tools do not provide an additional contribution. Previous spirometry experience was the most decisive parameter influencing adherence to the test protocol.

Abstract
OBJECTIVE Tumor necrosis factor-alpha (TNF-α) inhibitors are used to treat autoimmune diseases such as rheumatoid arthritis, ankylosing spondylitis, and inflammatory bowel disease. However, patients using TNF-α inhibitors are at a high risk of developing tuberculosis. Therefore, this study aimed to evaluate the compliance level of patients who were prescribed TNF-α-based tuberculosis prophylactic treatment. PATIENTS AND METHODS The study included 135 patients who were followed up at a tuberculosis dispensary between December 2020 and June 2021 and agreed to participate in the study. The study was conducted after obtaining necessary permissions from the institution, ethics committee, and patients. Data were collected using a questionnaire and evaluated using the Medication Adherence Report Scale (MARS). The MARS scale scores range from 5 to 25, with high scores indicating a high level of "medication compliance level". RESULTS Of the included patients, 42.2% were females, 46.7% were primary school graduates, and their mean age was 43.75±11.86 years. Additionally, 35.6% of patients had ankylosing spondylitis, among whom 54.1% had a disease duration of 1-5 years and 57.8% had been using TNF-α inhibitors for a year. Of the patients taking isoniazid (INH) for tuberculosis prophylaxis, 47.4% missed their prescribed INH doses, with "forgetfulness" being the reason in 28.9% of these patients. The patients had a mean MARS score of 15.71±6.18. CONCLUSIONS Patients using TNF-α inhibitors were found to have "moderate" compliance levels for INH-based prophylactic therapy. It is recommended that the compliance levels of patients and factors influencing their compliance should be regularly monitored.

Abstract
Background Tuberculosis (TB) is an important public health issue. Determining TB trend and seasonal variability provides useful information for designing treatment strategies and control programs. Aim The present study attempts to investigate the epidemiological trend and the seasonal variations. Materials and Methods TB data containing 2450 cases were collected over a period of seven years in the province of Diyarbakir in southeast Turkey. Trend function and seasonal variability were investigated by statistical curve fitting, surface fitting, and autoregressive time series analysis. Results The study revealed a gradually decreasing trend in the number of TB cases over a period of seven years. Total TB incidence had seasonal variations (P = 0.04); there was a greater number of TB cases between April and July, with a peak in June. There were significant monthly seasonal variations with June peaks among females (P < 0.001), in patients in the age groups of 0-15 (P < 0.001) and 36-45 years (P < 0.001), in new cases (P < 0.001) and in the patients with pulmonary TB (P = 0.01). The extra-pulmonary TB cases peak in May (P = 0.01). Pulmonary TB and TB patients in the 36-45 age group had summer peak, while the other groups peaked at spring. Conclusions Spring and summer peaks detected in total TB cases and in many subgroups indicate that multicenter and comprehensive clinical studies are needed to explain these variations.

Abstract
Introduction Boric acid, which has antiseptic and acidic properties, is used to treat external and middle ear infections. However, we have not found any literature about the effect of boric acid powder on middle ear mucosa and inner ear. Objective The purpose of this study is to investigate possible ototoxic effects of boric acid powder on cochlear outer hair cell function and histological changes in middle ear mucosa in a rat animal model. Methods Twenty healthy, mature Wistar albino rats were used in this study. The rats were divided into two groups, Group A and Group B, each of which consisted of 10 rats. Initially, the animals in each group underwent distortion product otoacoustic emissions testing of their right and left ears. After the first distortion product otoacoustic emissions test, a surgical microscope was used to make a small perforation in both ears of the rats in each group, and a second distortion product otoacoustic emissions test was used to measure both ears in all of the rats. Boric acid powder was applied to the right middle ear of the rats using tympanic membrane perforation, and the distortion product otoacoustic emissions were measured immediately after the boric acid powder application. The histological changes and distortion product otoacoustic emissions were evaluated three days later in Group A and 40 days later in Group B. Results No significant differences were found at all of the distortion product otoacoustic emissions frequencies. In Group A, mild inflammation of the middle ear mucosa was found on the third day after boric acid powder application. In Group B, boric acid powder caused mild inflammatory changes on the 40th day, which declined over time. Those changes did not lead to significant fibrosis within the mucosa. Conclusion In rats, boric acid powder causes mild inflammation in middle ear mucosa and it has no ototoxic effects on cochlear outer hair cell function in the inner ear of rats.

Abstract
Background Although a few case reports about hypertensive anaphylaxis (HA) are available in the present literature, there is no study about the prevalence of HA. In this study, we review our cases with anaphylaxis presenting with hypertension and ascertain its prevalence. The documents of the patients who had anaphylactic reactions after the procedures performed for the diagnosis and treatment of allergic diseases in GATA Haydarpasa Clinic of Allergy and Immunology between January 2010 and December 2014 were retrospectively reviewed. Within the study period, 324 patients had undergone 4332 procedures in which 62 of them had developed anaphylaxis. Results During the procedures, the rate of anaphylaxis was found to be 1.43 %. The rate of HA among the anaphylaxis patients was 12.9 % (8 of 62 patients). During treatments, 2 patients received adrenaline injections without any adverse reaction. Conclusions HA may be seen at a considerable rate during an anaphylactic reaction. Anaphylaxis and hypertension can be recovered by adrenaline injection when required. According to the best of our knowledge, this study is the first original study about the prevalence of HA in English-language medical literature.

Abstract
OBJECTIVE Sleep is a vital function for human beings, which can be affected by several factors. Chronic pain is one of these factors where it is the most frequent cause for seeking medical care in combination with insomnia. The aim of this study is to examine the prevalence and relationship between sleep disturbance and chronic pain. PATIENTS AND METHODS After approval, a total of 85 Family Medicine Units from over 170 in Tokat were randomly selected using a 50% sampling. A sample of 2635 subjects, over the age of 19 years, who were registered with the selected Family Medicine Units, were assessed due to gender, age group, and the urban/rural population size of Tokat using the stratified sampling method. The sample size distribution was calculated as 1515 urban subjects, 1120 rural subjects; 1345 female subjects, 1290 male subjects; 1123 subjects between 20-39 years of age, 1103 subjects between the ages of 40-64, and 409 subjects over 64 years of age. After sampling, subjects were invited to participate in the study via an invitation letter, and agreeing individuals were taken to the Family Medicine Unit for face-to-face meetings. Written, informed consent was obtained, along with demographic data. The presence of chronic pain was recorded. According to the presence of chronic pain, all subjects were separated into two groups as Group Chronic Pain and Group Non-Chronic Pain. The visual analog scale for pain intensity, and Pittsburgh Sleep Quality Index for sleep quality, were performed with all subjects. A multiple linear regression model was used to assess the predictors of sleep quality. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA), version 20.0. The statistical significance for all analyses was set at p < 0.05. RESULTS The mean global Pittsburgh Sleep Quality Index score of Group Chronic Pain (5.30 ± 4.29) was significantly higher than in Group Non-Chronic Pain (3.22 ± 3.30; p < 0.01). The mean Pittsburgh Sleep Quality Index scores of females (5.69 ± 4.40) were significantly higher than males (4.54 ± 3.96) in Group Chronic Pain (p = 0.000045). A total of 40.7% of patients in Group Chronic Pain, and 21.9% in Group Non-Chronic Pain demonstrated poorer sleep quality according to the Pittsburgh Sleep Quality Index scores, with a cut-off level > 5. A moderate positive correlation was found between the global Pittsburgh Sleep Quality Index and Visual Analog Scale scores (r = 0.310, p < 0.01). A multiple linear regression analysis showed that age, gender, income, Visual Analog Scale, and presence of depression were the significant predictors for Pittsburgh Sleep Quality Index score. CONCLUSIONS The current study revealed that chronic pain and pain intensity are important predictors of sleep quality.

Abstract
BACKGROUND Isoflurane is a volatile anaesthetic that has been commonly used since 1980. The major metabolites of isoflurane are fluoride ion and trifluoroacetate, both excreted in the urine. AIM This study manage to show the histopathological findings of ingested isoflurane on liver, kidney and lugs in an animal model. Twenty-one rabbits were selected and divided into three groups: Group Isoflurane-5 (I-5); Group Isoflurane-10 (I-10); and Group Control (C). Each group consisted of seven rabbits. I-5 and I-10 received 5 ml/kg and 10 ml/kg of liquid isoflurane, respectively, via nasogastric tube, while C received 5 ml/kg saline (0.9% NaCI). All animals in I-5 and I-10 were sacrificed without anesthetic drug administration. Tissue samples from livers, kidneys and lungs were collected, preserving tissue unity and avoiding infliction of any trauma. Samples were fixed in 10% formalin solution, embedded in paraffin blocks and sliced into 5 μm sections. To investigate the effects of isoflurane, sections were examined under light microscope and histopathological changes were scored. RESULTS Mean injury scores and the appearance of portal lymphocyte infiltration in liver samples showed significant increases in I-5 and I-10 compared to C (p = 0.005, p = 0.001 and p = 0.001, respectively). Mean lung injury scores revealed significant increases after isoflurane treatment in I-5 and I-10 compared to C (p = 0.026 and p = 0.017, respectively). CONCLUSIONS Ingested isoflurane led to mild liver and lung injuries in rabbits.

Abstract
OBJECT The object of this study was to evaluate facial nerve outcomes in the surgical treatment of large vestibular schwannomas (VSs; ≥ 2.5 cm maximal or extrameatal cerebellopontine angle diameter) based on both the operative approach and extent of tumor resection. METHODS A PubMed search was conducted of English language studies on the treatment of large VSs published from 1985 to 2011. Studies were then evaluated and included if they contained data regarding the size of the tumor, surgical approach, extent of resection, and postoperative facial nerve function. RESULTS Of the 536 studies initially screened, 59 full-text articles were assessed for eligibility, and 30 studies were included for analysis. A total of 1688 tumor resections were reported. Surgical approach was reported in 1390 patients and was significantly associated with facial nerve outcome (ϕ= 0.29, p < 0.0001). Good facial nerve outcomes (House-Brackmann Grade I or II) were produced in 62.5% of the 555 translabyrinthine approaches, 65.2% of the 601 retrosigmoid approaches, and 27.4% of the 234 extended translabyrinthine approaches. Facial nerve outcomes from translabyrinthine and retrosigmoid approaches were not significantly different from each other, but both showed significantly more good facial nerve outcomes, compared with the extended translabyrinthine approach (OR for translabyrinthine vs extended translabyrinthine = 4.43, 95% CI 3.17-6.19, p < 0.0001; OR for retrosigmoid vs extended translabyrinthine = 4.98, 95% CI 3.57-6.95, p < 0.0001). There were 471 patients for whom extent of resection was reported. There was a strong and significant association between degree of resection and outcome (ϕ= 0.38, p < 0.0001). Of the 80 patients receiving subtotal resections, 92.5% had good facial nerve outcomes, compared with 74.6% (n = 55) and 47.3% (n = 336) of those who received near-total resections and gross-total resections, respectively. In the 2-way comparison of good versus suboptimal/poor outcomes (House-Brackmann Grade III-VI), subtotal resection was significantly better than near-total resection (OR = 4.21, 95% CI 1.50-11.79; p = 0.004), and near-total resection was significantly better than gross-total resection (OR = 3.26, 95% CI 1.71-6.20; p = 0.0002) in producing better facial nerve outcomes. CONCLUSIONS In a pooled patient population from studies evaluating the treatment of large VSs, subtotal and near-total resections were shown to produce better facial nerve outcomes when compared with gross-total resections. The translabyrinthine and retrosigmoid surgical approaches are likely to result in similar rates of good facial nerve outcomes. Both of these approaches show better facial nerve outcomes when compared with the extended translabyrinthine approach, which is typically reserved for especially large tumors. The reported literature on treatment of large VSs is extremely heterogeneous and minimal consistency in reporting outcomes was observed.

Abstract
The objective of the study is to determine whether topical halofuginone (HF) application has an impact on prolonging the time for healing of myringotomy incision, and to investigate histopathologic effects of HF on tympanic membrane (TM) in rat model. Forty rats with normal eardrums were involved in this study. The study group and control group consisted of 30 and 10 rats, respectively. A posterior incision 1 mm in diameter was made on healthy eardrums of the rats. Following incision, gelfoam soaked with HF hydrobromide of 30 mg/dl was applied on the perforation in study group, whereas gelfoam soaked with isotonic saline was applied on the perforation in control group. On days 1, 3, 7, 10, 14, 18, 21, 24, 27, and 30, otoendoscopic evaluation of eardrums under general anesthesia was conducted and perforations were screened. A rat of each group was killed in control days and TMs were dissected to evaluate histopathological changes. The average times for patency of perforation in study and control groups were 21.43 and 7.50 days, respectively. The difference was found to be statistically significant (p < 0.05). Histopathological evaluation revealed that HF reduces hyalinisation and fibrosis in eardrum, when compared with the control group. In conclusion, HF significantly delays closure time of myringotomies in rat model. However, this delay may not be enough for recovery of otitis media with effusion.

Abstract
Middle ear adenoma with neuroendocrine differentiation is an uncommon tumor of the tympanic cavity. The terminology of this entity has suffered due to a poor understanding of the differentiation of these neoplasms, and has included both "adenoma" as well as "carcinoid tumor." Immunohistochemical techniques have helped clarify that these tumors all share elements of neuroendocrine differentiation. Occurrences of this tumor in the pediatric population are extremely rare. In the world literature, only three pediatric cases of middle ear adenoma with neuroendocrine differentiation have been described. We report the youngest case to date of middle ear adenoma with neuroendocrine differentiation, in a 13-year-old boy. We discuss the differential diagnosis, surgical management, and pathology of this entity.

Abstract
Objective: To investigate histologic changes in the mucosa of rat middle ear after implantation of three different support materials. Study Design: A prospective, controlled animal study. Subjects and Methods: Three types of absorbable materials were implanted into the middle ear cavity of rats: (1) Gelfoam (purified gelatin) (Pharmacia & Upjohn Company, New York, NY), (2) Sepragel (viscoelastic gel composed of cross-linked polymers of hyaluronan) (GENZYME Corp, Ridgefield, NJ), and (3) Nasopore (a biodegradable/fragmentable, synthetic polyurethane foam) (Polyganics, Groningen, The Netherlands). Rats were sacrificed after 3 and 20 days to ascertain early and late histologic changes. The bulla of each rat was excised and prepared for microscopic examination. The histologic changes were evaluated by observation of the middle ear cavity and mucosa in terms of polymorphonuclear leucocytes (PMNL), macrophages, giant cells, fibroblasts and other cells, fibrosis, and remnant materials. Results: The histologic appearance of gelfoam-treated middle ears was characterized by more severe acute inflammation in the short-term and prominent fibrosis in the long-term in comparison with sepragel- and nasopore-treated groups. Nasopore appeared to be prone to remnant formation and reorganization by means of fibroblastic activity. Conclusion: Compared with gelfoam, both sepragel and nasopore caused less histologic alterations.

Abstract
OBJECTIVES Removal of head and neck neoplasms, especially those of the parotid gland and those of the internal auditory canal and cerebellopontine angle, often requires microdissection of the facial nerve. Displacement or splaying of the nerve can make it difficult to identify facial nerve fibers and/or distinguish them from surrounding tissues. Here we tested a method of labeling the facial nerve with fluorescent lipophilic dyes as a method of providing intraoperative visual confirmation of nerve fibers. METHODS The facial nerves of adult rats were retrogradely labeled with 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI), 3,3'-dioctadecyloxacarbocyanine perchlorate (DiO), or 3,3'-dilinoleyloxacarbocyanine perchlorate (Fast DiO) either by direct application to the nerve sheath or by microinjection into the facial muscles. The nerves were examined 30 days after dye application by means of a dissecting stereomicroscope equipped with epifluorescence filters. RESULTS Of the dyes tested, Fast DiO proved to be the most effective, providing labeling of the nerve sufficient to be seen with combined fluorescent and bright field stereomicroscopy. Nerve conduction studies indicated that fluorescent labeling did not adversely affect nerve function. CONCLUSIONS These results raise the possibility of using fluorescent lipophilic dyes to label nerves as a method of enhancing identification and distinguishing nerve fibers during surgery.

Abstract
AbstractObjective:To evaluate effectiveness of 5 mW laser irradiation in the treatment of chronic tinnitus.Study design:Prospective, randomised, double-blind study.Methods:This investigation included 66 ears in 45 patients with chronic unilateral or bilateral tinnitus. A 5 mW laser with a wavelength of 650 nm, or placebo laser, was applied transmeatally for 15 minutes, once daily for a week. A questionnaire was administered which asked patients to score their symptoms on a five-point scale, before and two weeks after laser irradiation. A decrease of one scale point, regarding the loudness, duration and degree of annoyance of tinnitus, was accepted to represent an improvement.Results:The loudness, duration and degree of annoyance of tinnitus were improved, respectively, in up to 48.8, 57.7 and 55.5 per cent of the patients in the active laser group. No significant improvement was observed in the placebo laser group.Conclusion:Transmeatal, low power (5 mW) laser irradiation was found to be useful for the treatment of chronic tinnitus.

Abstract
OBJECTIVE The aim of the study was to assess the antifibrotic effect of systemically applied halofuginone after subglottic injury. MATERIALS AND METHODS After standardized trauma to subglottic area, rats were divided into two groups: a study group that received treatment and a control group that did not. The rats were treated with 0.1 mg/kg/day intraperitoneal halofuginone injection for 30 days. The larynx specimens were examined histopathologically under light microscope for epithelization, inflammation, necrosis, and fibrosis. RESULTS The fibrosis indexes of the treated group were significantly less than those of the control group (P < .01). CONCLUSIONS Systemically applied halofuginone hydrobromide decreases fibrosis/scar tissue formation secondary to experimentally induced acute subglottic trauma.

Abstract
We report a patient who developed sudden, bilateral, sensorineural hearing loss during therapeutic use of iloprost for Raynaud's phenomenon. The sudden hearing loss was attributed to iloprost use and completely reversed in eight days with conservative therapy. Iloprost may be a potentially ototoxic drug, causing sudden hearing loss.

Abstract
PURPOSE To determine the prevalence and type of human papilloma virus deoxyribonucleic acid (DNA) in cases of laryngeal squamous cell carcinoma. METHODS We analysed the prevalence of human papilloma virus infection in archived paraffin block specimens taken from 99 cases of laryngeal squamous cell carcinoma between 1990 and 2005, using polymerase chain reaction techniques. Biopsy specimens from five proven verrucous skin lesions were used as positive controls, and peripheral blood samples from five healthy volunteers were used as negative controls. RESULTS Four test samples were found to have inadequate deoxyribonucleic acid purity and were therefore excluded from the study. Human papilloma virus deoxyribonucleic acid was detected in seven of 95 cases of laryngeal squamous cell carcinoma (7.36 per cent). Human papilloma virus genotyping revealed double human papilloma virus infection in three cases and single human papilloma virus infection in the remaining four cases. The human papilloma virus genotypes detected were 6, 11 and 16 (the latter detected in only one case). CONCLUSION In our series, a very low human papilloma virus prevalence was found among laryngeal squamous cell carcinoma cases. The human papilloma virus genotypes detected were mostly 6 and/or 11, and 16 in only one case. To the best of our knowledge, this is the first report of human papilloma virus prevalence in laryngeal squamous cell carcinoma, based on polymerase chain reaction genotyping in a Turkish population.

Abstract
OBJECTIVE This study was undertaken to compare the effects of radiofrequency and injection snoreplasty on the histological structure of the soft palate in an animal model. STUDY DESIGN AND SETTING This is a blinded, controlled histologic evaluation of rat soft palates that underwent separate palatal interventions. Fifty rats were divided into 5 groups of 10 rats (Group 1 = injection snoreplasty [IS], Group 2 = IS + steroid, Group 3 = saline injection, Group 4 = radiofrequency ablation [RFA], and Group 5 = no intervention). The animals were sacrificed after 24 hours, 1 week, 3 weeks, and 5 weeks. Then the soft palates were subjected to histological analysis. RESULTS Histological analysis demonstrated normal remucosalization in all specimens, with fibrosis increased in Group 1. Interstitial edema was minimal in Group 2. Keratinization was most apparent in Group 4. CONCLUSION Radiofrequency and injection snoreplasty stiffen the rat soft palate compared with controls.

Abstract
We report the case of a peripheral osteoma mimicking a benign tumor in the left parotid gland of a 75-year-old woman. The clinical presentation of the painless mass on the lateral surface of the mandibular ascending ramus was suggestive of a benign parotid tumor such as a pleomorphic adenoma. It was diagnosed using computed tomography (CT) and further delineated using 3D spiral CT scanning. Mandibular osteoma should be considered in differential diagnosis of parotid masses, which can be revealed by conventional radiographs.

Abstract
Juvenile spring eruption is a photodermatosis characterized by the development of papules and vesicles on the light-exposed helix of the ears after sun exposure, usually in the springtime. It mainly affects boys and young male adults, and has a tendency to occur in the form of small epidemics. We report an outbreak in a group of soldiers who were performing military exercises during cold and sunny weather during a midwinter season. The clinicopathologic features and laboratory test results are described in two of these cases.

Abstract
A 13-month-old cochlear implant recipient underwent routine device activation. Three months postoperatively, the patient sustained a fall with contact to the area of the implant without immediate complication. Ten months postoperatively, the position of the external coil appeared to have moved and the patient did not seem to be responding as well to sound. Audiological testing could not elicit normal device impedances. AP and lateral plain radiographs of the skull revealed migration of the internal magnet from its position within the internal coil to a position over the receiver/stimulator. This is the first known published case of cochlear implant magnet migration.
