RESUMO

AIM: The current study was aiming to investigate the relation between vitamin D, retinopathy, and hearing loss among type 2 diabetes mellitus (T2DM) patients. METHODS: Cross-sectional study carried on 638 subjects aged between 20 and 60 years who visited the Endocrinology, Ophthalmology, and ENT Outpatient Clinics of the Medipol Hospital during the period from March 2016 to May 2017. Two audiometers Grason Stadler GSI 61 and Interacoustics AC40 Clinical audiometer were used to evaluate the hearing loss. Risk factors for diabetic retinopathy were evaluated, including age, sex, diabetes duration, glycated hemoglobin (HbA1c), hypertension, and lipid profiles. RESULTS: The mean age (± SD, in years) for retinopathy with hearing loss versus normal subjects was 47.7 ±10.2 versus 48.5±9.1. The associated risk factors were significantly higher in T2DM with hearing loss, hypertension (32.6% versus 15.7%), tinnitus (40.0% versus 18.0%), vertigo (59.7% versus 26.8%), and headache (54.9% versus 45.3%), than in normal hearing diabetes. There were statistically significant differences between hearing impairment versus normal hearing for vitamin D [19.40±9.71 ng/ml versus 22.67±9.28 ng/ml; p<0.001], calcium, magnesium, phosphorous, cholesterol, HDL-C, LDL-C, albumin, systolic blood pressure [131.70±9.25 Hg versus 127.73±11.98 Hg], diastolic blood pressure [82.20±8.60 mm Hg versus 79.80±8.20 mm Hg], and microalbuminuria. Multivariate logistic regression analysis revealed that variables such as vertigo, duration of DM, mobile/I pad phone, vitamin D deficiency, sleeping disturbance, headache, frequently TV watching, tinnitus, cigarette smokers, and hypertension were considered at higher risk as a predictors of retinopathy with hearing loss among diabetic patients. CONCLUSION: Vitamin D deficiency is considered as a risk factor for diabetic retinopathy and hearing loss among diabetic patients. Meanwhile, hyperglycemia could be considered as a modifiable risk factor for diabetic retinopathy; tight glycemic control may be the most effective and important therapy for improving quality of life and substantially reducing the incidence of retinopathy and in T2DM patients.

RESUMO

This study was aimed to evaluate the efficacy of treatment modalities for minimizing salivary gland damage caused by radiotherapy. Forty rats were divided into five groups. Group 1 had no irradiation or any treatment. Group 2 underwent only 15 Gy single dose radiotherapy. N-acetylcysteine, dexamethasone, hyperbaric oxygen treatment were given, respectively to the group 3, 4 and 5 for 5 days. 15 Gy single dose radiotherapy was applied to the group 3, 4 and 5 on the second day. Pyknosis, lysis, and vacuolization were examined in ductal cells and pyknosis, lysis, vacuolization, inflammation and collective duct damage in acinar cells. Dexamethasone and hyperbaric oxygen did not prove to have a positive effect on acinar and ductal cell. N-acetylcysteine-applied group had statistically significantly lower amount of damage. We determined that the decrease of ductal and acinar cell damage in parotid glands of N-acetylcysteine-applied rats was more distinct and statistically.

RESUMO

OBJECTIVES: Smoking is one of the most common harmful habits in the world, especially common among young adult male population in Turkey. The purpose of this study was to evaluate the effect of smoking on the young adults' male voice using multidimensional voice assessment methods. STUDY DESIGN: This is a case-control study. METHODS: The study included 109 young adult men, 51 nonsmokers and 58 smokers between the ages of 20 and 34 years. The voice evaluation protocol consisted of voice handicap index (VHI), maximum phonation time (MPT), and perceptual, acoustic, and videostroboscopic analyses. RESULTS: A statistically significant increase for physical, physiological, and total scores of VHI was found in smokers group (P < 0.05). MPT showed significantly lower values among smokers (P < 0.05). There were no significant changes in perceptual analysis of voice samples between smoker and nonsmoker groups. There were no significant changes in any of the acoustic parameters between smoker and nonsmoker groups. Results of videostroboscopic analysis showed significant relationships between smoking and increased vocal fold erythema (P < 0.05). In addition, significantly asymmetry, amplitude, and periodicity abnormality of vocal fold movements were observed in smoker group during phonation (P < 0.05). CONCLUSIONS: The results of this study indicate that observable signs of laryngeal irritation and disturbed phonatory physiology occur even in young adults with relatively brief smoking habits. Subjective symptoms of smoking on voice appear to occur earlier than objective findings.

RESUMO

BACKGROUND: Tumor necrosis factor-related associated-inducing ligand (TRAIL) is a death ligand currently under clinical trials for laryngeal carcinoma. METHODS: Paraffin-embedded tissues from 40 patients with laryngeal carcinoma and 20 patients with benign laryngeal pathologies were retrospectively analyzed using immunohistochemistry in terms of distribution and intensity, and for final analysis of immunoreactivity of receptors, H-score was used. The study group was assessed in terms of localization, lymph node staging, tumor stage, overall survival, disease-free survival, locoregional control, perineural invasion, and vascular invasion. RESULTS: The H-score of decoy-R2 (DcR2) staining were increased significantly in tumor tissue (p = .04). A significantly greater increase in terms of H-score of DR5 receptor staining (p = .06) was detected in tumor tissue. CONCLUSION: TRAIL-mediated gene therapy may not be effective. Indeed, the findings may indicate treatment resistance. TRAIL and TRAIL receptor levels were not associated with prognosis © 2015 Wiley Periodicals, Inc. Head Neck 38: E535-E541, 2016.

RESUMO

INTRODUCTION: Most commonly used treatment modalities for acute acoustic trauma (AAT) include steroid and hyperbaric oxygen (HBO2) therapy. The aim of this study is to investigate the effectiveness of combined steroid and HBO2 therapy in patients who develop AAT during firearms training and the effect of delay to treatment on treatment success. MATERIALS AND METHODS: Patients admitted with the complaint of hearing loss after firearms training between January 2011 and April 2013 were evaluated retrospectively. Patients were grouped according to date of admission; patients admitted within the first 10 days were included in Group A and those admitted between Days 11 and 30 in Group B. RESULTS: A total of 48 patients (73 ears) with AAT were included. There were 37 ears in Group A and 36 ears in Group B. The number of ears with complete treatment response, partial treatment response and treatment failure (unchanged) were one (2.7%), 7 (18.9%) and 29 (78.4%) in Group A and 0 (0%), 3 (8.3%) and 33 (91.7%) in Group B, respectively. There was no statistically significant difference between the groups (p = 0.095). Late-term results (at Week 6) demonstrated Group A showed higher hearing gain on high frequencies than Group B (p < 0.05), but this result was not consistent with clinical outcome results. CONCLUSION: The success rate of combined HBO2 and steroid therapy was very low in our study. However, early initiation of treatment results in better outcomes. Protective measures have great importance in preventing AAT.

RESUMO

Squamous cell carcinoma is the most common malignancy of the soft palate. In some cases, it mimics mycobacterial infections and in others it can develop against the background of a previous tuberculosis infection. Here we report a case of a 68-year-old male who presented with squamous cell carcinoma of the soft palate. He had metastatic lymphadenopathy on the right side and, simultaneously, two caseating granulomatous lymphadenopathies without metastatic lymph nodes on the left side. The patient was treated with soft palate excision and bilateral functional neck dissection. Standard antitubercular therapy and radiotherapy were added postoperatively. To our knowledge this is the first case in the English-language medical literature of a head and neck cancer in the setting of tuberculosis. Tuberculosis may mimic head and neck cancers and vice versa, and both conditions may have atypical clinical and radiological presentations. Our case points out the need to consider tuberculosis in the differential diagnosis of squamous cell carcinoma of the head and neck.

RESUMO

It is well known that desensitization treatment with aspirin can significantly improve symptoms and quality of life in patient with aspirin-exacerbated respiratory disease. However, its mechanism has not been clearly understood yet. In this case report, 41-year-old male patient was referred to our allergy and immunology department with complaints of chronic rhinosinusitis including postnasal discharge, sneezing, facial pain/pressure, waking up tired, nasal obstruction, smell loss for a long time. According to the patient, the complaints were controlled partially with nasal steroid and antihistamines, and single dose parenteral depot steroids were highly effective in controlling the symptoms and each time this effect lasted at least three weeks. The patient was told to use aspirin when needed analgesic and he started to use aspirin 500 mg bid. po for 10 days for his pain in the joints. The patient stressed the superiority of aspirin over other drugs including oral antihistamine and LTA and its equality to systemic steroid drugs in suppressing symptoms. It seemed that aspirin had positive effects in allergic inflammation at least in some subset of aspirin tolerant patients with chronic sinusitis.

RESUMO

The aim of this study is to evaluate the effects of intrapolyp, systemic and local corticosteroid treatment modalities on MMP-9 and TIMP-1 level in polyp tissues. This study included 71 patients and five groups. Group A treated with oral methylprednisolone, Group B, treated with topical steroid spray, Group C treated with intralesional triamcinolone acetonide, Group D patients with nasal polyposis who has not given any medication, Group E had surgery for concha bullosa without nasal polyp disease. Samples from group A were collected endoscopically 1 day after treatment was stopped. Group B samples were collected at the end of the first month. Video guided sample collection from Group C was also performed on the 7th day after treatment. MMP-9 and TIMP-1 levels were measured by Enzyme-linked immunosorbent assay method. When we compared the MMP-9 levels of all groups, there were no significant differences. There was significant difference of TIMP-1 level between Groups C and E (pC-E = 0.0019), however there was no difference among the level of the other groups. When MMP-9/TIMP1 rates of all groups were compared, there were significant difference between Group A and D (pA-D = 0.005) and between Group A and E, also between Group C and E. Our study is the first study to evaluate the effects of different corticosteroid treatment modalities on MMP-9 and TIMP-1 in nasal polyps and concluded that corticosteroid did not do a significant impact on this pathway.

RESUMO

OBJECTIVE: The purpose of this study was to compare the apoptotic responses to systemic, topical, and intrapolyp injection of glucocorticoid with no treatment in nasal polyps. STUDY DESIGN: Prospective, randomized controlled study. SETTING: Tertiary training hospital. SUBJECTS AND METHODS: The study was performed on 48 patients with nasal polyposis in the Department of Otorhinolaryngology between 2008 and 2009. Patients were assigned to 1 of 4 groups of 12 patients. Group A was treated with oral methylprednisolone 1 mg/kg/d, and the dose was tapered gradually. Group B received 0.3 mL triamcinolone acetonide (40 mg/mL), which was injected into polyp tissue. Group C was treated with topical 55 µg triamcinolone acetonide 2 times daily for 1 month. Group D received no medication. Samples were collected endoscopically after the seventh day for groups A and B, the first month for group C, and the first visit for group D. Apoptotic indexes were determined using the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method. RESULTS: Statistically significant differences in apoptotic index were found between each steroid-medicated group and the control group (P (D-A) = .0001; P (D-B) = .003; P (D-C) = .026) and between groups A and C (P (A-C) = .012). Group B did not differ significantly from either group A or C (P (A-B) = .11; P (B-C) = .75). CONCLUSIONS: The apoptotic index in nasal polyps treated with systemic, topical, and intrapolyp injection forms of glucocorticoids was higher than that in the control group. Systemic steroid treatment induced the most apoptosis.

RESUMO

We conducted a study to determine the presence or absence of Helicobacter pylori and laryngopharyngeal reflux (LPR) in 43 previously untreated patients who had presented with a laryngeal lesion. Our aim was to determine if there was any association among H pylori, LPR, and laryngeal lesions. H pylori status was determined by real-time polymerase chain reaction (PCR) assays of biopsy tissue obtained during direct laryngoscopy. The presence or absence of LPR was determined on the basis of patients' reflux symptom index (RSI) and reflux finding score (RFS), which were based on their questionnaire responses and findings on endoscopic examination of the larynx, respectively. Patients with an RSI of 14 or more and/or an RFS of 8 or more were considered to have LPR. H pylori was present in 24 patients (55.8%) and absent in 19 (44.2%)-not a statistically significant difference. The prevalence of LPR was higher than the prevalence of H pylori; it was present in 30 patients (69.8%) and absent in 13 (30.2%). The difference was statistically significant (p = 0.01). We found no association between H pylori status and LPR status. Additionally, we analyzed two subgroups based on whether their lesions were benign or malignant/premalignant and found a significant relationship between LPR positivity and the presence of malignant/premalignant laryngeal lesions (p = 0.03). We found no association between H pylori status and either of the two subgroup categories.

RESUMO

The aim of this study was to evaluate hydroxyproline levels in nasal specimens from patients with nasal polyps, and to examine hydroxyproline levels after nasal steroid spray and oral steroid treatments. This study was performed on 41 patients. The subjects were divided into four groups: no medication group (group A, n 11), oral methylprednisolone group (group B, n 8), topical steroid spray group (group C, n 8) and control group (group D, n 14). Nasal polyp samples were collected endoscopically. Healthy subjects were studied as a control group, and their nasal samples were taken during turbine reduction surgery. All samples were analyzed using the immunocytochemistry method. Hydroxyproline levels were investigated and compared with the control group. Mean hydroxyproline levels in groups A-D were 98.48, 24.20, 8.97 and 4.52, respectively. The hydroxyproline levels were significantly higher in group A compared with that of group D. The treatment that revealed significant decreases in hydroxyproline levels was group C. Although there was also a noticeable reduction in group B, there were no statistically significant differences between group B and group A. Our study revealed a significant correlation between nasal polyp and hydroxyproline levels. The hydroxyproline levels were significantly higher in nasal polyps. Both oral and topical steroid treatments decrease hydroxyproline levels in nasal polyps. Thus, in theory, steroid treatment can directly decrease hydroxyproline levels by inhibiting proline hydroxylase and indirectly by lowering the inflammatory process.

RESUMO

OBJECTIVES: In this study, we investigate the prevalence of chronic otitis media (COM) in young men. PATIENTS AND METHODS: Twenty thousand consecutive young men (mean age 22 years) who were under election for high performance military positions were examined by two otolaryngologists in the Military Hospital, Izmir. The otologic examination findings were noted. We evaluated the patients who have tympanic membrane perforation, retraction, adhesion, myringosclerosis and the patients who had underwent surgery before. RESULTS: Three-hundred and fifty-five young men (1.77%) had COM. Other findings were retraction (n=66; 0.33%), adhesion (n=36; 0.18%), myringosclerosis (n=720; 3.6%) and cerumen (n=3200; 16%). We found out that five (0.025%) of the cases had radical mastoidectomy surgery and 16 (0.08%) of them had tympanoplasty. CONCLUSION: The prevalence of COM in young men is 1.77%. Although our study has a limitation because all of our samples are young men, the study is unique due to its large sample size.

RESUMO

A 22-year-old man was admitted with complaints of dyspnea and hoarseness. Laryngoscopy and computed tomography of the neck revealed a 1.5 x 2-cm solid mass obstructing the trachea. The black, pedunculated mass was completely removed through a tracheal incision, and a paratracheal lymph node dissection was performed. Histopathologic examination revealed nodular-type mucosal malignant melanoma. Cranial and thoracic computed tomography, abdominal ultrasonography, and histopathologic examination of the paratracheal lymph nodes showed no metastases. No recurrence has been noted in more than 3 years of follow-up.

RESUMO

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.

RESUMO

OBJECTIVE: To compare the surgical results of uvulopalatopharyngoplasty (UPPP) and uvulopalatal flap (UPF) procedures in the treatment of primary snoring. MATERIALS AND METHODS: Two study groups were formed and UPPP and UPF procedures were performed. All patients were stratified according to the modified Friedman staging system. Patients with tonsil size 2-4, palatal position scale grade 2, and body mass index lower than 30 were enrolled in the study. The success of surgical procedures was evaluated by applying a snoring questionnaire and Epworth sleepiness scale preoperatively and 90 days after the operation. Patients were followed for postoperative pain and other complications. RESULTS: Snoring was relieved in 85% of UPPP and in 83.3% of UPF patients 90 days after the operation. Postoperative pain complaint was more prominent in the UPPP group and mean duration of pain was significantly longer compared with the UPF group. CONCLUSIONS: Despite similar success rates in the short-term, we can say that the UPF procedure is more practical and comfortable when compared to the UPPP in the military setting.

RESUMO

OBJECTIVE: The aim of the study is to ascertain the antifibrotic effect of topically applied halofuginone after acute subglottic injury. MATERIALS AND METHODS: After standardized trauma to subglottic area, rats were divided into two groups: the study group that received treatment and the control group that did not. The subjects were treated with topical application of cottonoid soaked in 30 mg/dL halofuginone solution for 5 minutes after subglottic trauma. The larynx specimens were examined histopathologically by light microscopy to assess fibrosis, epithelialization, inflammation, and necrosis. RESULTS: The fibrosis indexes of the treated group were significantly less than those of the control group (P < 0.05). CONCLUSIONS: Topically applied halofuginone hydrobromide decreases fibrosis/scar tissue formation secondary to experimentally induced acute subglottic trauma.

RESUMO

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.

RESUMO

Chiari malformation refers to caudal displacement of posterior fossa structures through the foramen magnum in the cervical canal and is classified according to the severity of displacement and accompanying cranial nerve and cervical pathologies. We presented a 24-year-old male patient who had isolated unilateral paralysis of the hypoglossal nerve and vagus nerve, with thyroid cartilage asymmetry. Chiari type I malformation was diagnosed by craniospinal magnetic resonance imaging. Suboccipital craniectomy and cervical 1-level large partial laminectomy were performed by the neurosurgery department. No improvement was observed in hypoglossal and vagal paralysis during an 18-month follow-up.
