Abstract Conclusions As is known, this study is the first study to evaluate the effect of inhaled steroids on laryngeal microflora. The data support that ICS usage causes changes in the larynx microflora. Purpose The aim of this study was to determine the alteration in larynx microbial flora of the patients treated with ICS comparing the culture results of a control group. In addition, laryngeal microflora was compared to the smears obtained from the vallecula and pharynx. Materials and methods The study included 39 patients (mean age = 45.56 ± 12.76 years) who had been using a corticosteroid inhaler and control group consisting of 27 persons (mean age = 43.07 ± 13.23 years). Culture samples were obtained from the pharynx, larynx, and vallecula in the patient and control groups, and they were evaluated in the microbiology laboratory. Obtained culture results were named by the same microbiologist according to the basic microorganism classification method. Results Coagulase-negative staphylococci (CNS), Streptococcus viridians (VGS) and candida albicans were detected to grow significantly more in the patient group in all three anatomic localizations compared to the control group. Neisseria spp, basillus spp, and Non-viridans alpha-hemolytic streptococcus were detected to grow significantly more in the control group in all three anatomic localizations compared to the patient group.

Background Nasal polyposis (NP) is the most frequent cause of nasal masses. Despite considerable research on the subject, its etiology has not been fully elucidated, and effective treatment methods have not been developed. Some etiological factors causing low or high expression of genes in genetically predisposed individuals may play a role in the pathogenesis of the disease. The purpose of this study was to assess the relation between levels of vitamin D receptor (VDR) gene expression and serum vitamin D with NP. Material/Methods The study included 46 subjects with NP (NP group) and 40 volunteers (control group). Nasal polyp tissue samples were taken from the NP group and nasal mucosa samples were taken from the control group. Levels of VDR gene expression in the tissue samples were assessed using the real-time polymerase chain reaction (RT-PCR) method. Results Mean serum 25(OH)D levels were 13.38±14.08 ng/ml in the NP group and 10.57±6.44 ng/ml in the control group (p=0.249). VDR gene expression was present in 17.5% of the NP group and 3.3% of the control group, and the difference between the 2 groups was statistically significant (likelihood ratio χ2=3.887; p=0.049). Conclusions This is the first study to assess levels of VDR gene expression in subjects with NP. Our results suggest that VDR gene expression may be associated with the pathogenesis or progression of NP.

Objectives To evaluate the effect of weight percentile on deep neck infections in children. Methods A retrospective evaluation of 79 patients who were treated for deep neck infections. The patients were divided into six groups according to weight percentile. Patients who had systemic and/or congenital disease were excluded. Their demographics, etiology, localization, laboratory, and treatment results were reviewed. Results In total, 79 pediatric patients were recorded: 48.1% were females and 51.9% were males, with a mean age of 7.3 years. In total, 60 patients were under the 50th percentile according to their weight versus all children. The anteroposterior triangle (29.1%) and submandibular (26.5%) spaces were most commonly involved with deep neck infection. However, the anteroposterior triangle space was the highest in the group below the 3rd percentile (44.4%). In the blood analysis, white blood cell levels in patients with at percentile values of 75-50 were higher than other groups (P<0.05). Significant differences were found between C-reactive protein and hemoglobin levels and diameter of abscesses. The need for surgical drainage in patients in lower percentiles was higher. The patients who needed surgical drainage consisted of 56 patients (93.3%) below the 50th percentile and 9 patients (100%) below the 3rd percentile. Conclusion Deep neck infection is more insidious and dangerous in low-weight-percentile children, especially those having low white blood cell counts, low hemoglobin levels, and high C-reactive protein in laboratory results.

Background The purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds. Material/Methods Forty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8000 Hz) and extended high (EH) (9000–20000 Hz) frequency audiometry. The fasting plasma glucose, insulin, FSH, LH, total testosterone, and sex hormone-binding globulin were measured in all patients. Results The mean hearing thresholds at EH frequencies were statistically significantly higher in the PCOS group than in the control group (p=0.001 right ear and p=0.015 left ear). There were significant positive correlations among free testosterone index (FTI) values and hirsutism scores with EH frequency hearing thresholds. Conclusions At pure-tone audiometry (PTA) EH frequencies, we detected significantly higher hearing thresholds in PCOS patients than in controls. We also determined that elevated FTI and hirsutism score were positively correlated with elevated hearing thresholds in EH frequencies. These findings support that hyperandrogenism can play a role in the elevation of hearing thresholds in PCOS.

Objectives: Paraoxonase-1 (PON1) prevents oxidative stress by inhibiting the oxidation of cell membrane lipids by the reactive oxygen species that form during acute and chronic inflammation. The aim of this study was to investigate serum PON1 activity and oxidative stress in patients with chronic otitis media (COM). Methods: Fifty consecutive patients with COM and 55 controls were enrolled in the present study. The patients were divided into two groups according to the presence of cholesteatoma. The serum PON1 arylesterase activities and lipid hydroperoxide (LOOH) levels were determined. Results: Serum paraoxonase and arylesterase activities were significantly lower in the COM patients than in the controls (P < 0.001 for all comparisons), whereas the LOOH levels were significantly higher (P < 0.001). Discussion: These results indicated that a lower level of PON1 activity was associated with an oxidant–antioxidant imbalance. In addition, decreased PON1 activity may play an important role in the pathophysiology of COM.

Objectives To underline the effect of oxidative stress in chronic otitis media with and without cholesteatoma and to compare the oxidative stress values in the serum and tissue specimens in these two forms. Methods The study included a total of 75 individuals, 35 cases with chronic otitis media (COM; 16 females and 19 males) and a healthy control group of 40 cases (20 females and 20 males). The COM patient group was comprised of 18 patients with cholesteatoma and 17 patients without cholesteatoma. All patients underwent mastoidectomy. Serum specimens were taken prior to surgery and diseased tissue specimens from the ear were obtained during surgery from all patients. Only serum specimens were taken from the healthy control cases. The malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GHPx) were measured in the serum and tissue samples of the patient group and in the serum specimens of the control group. Results The age ranged from 14 to 48 years in the patient group (mean age, 20.4±12.2 years) and from 19 to 40 years in the control group (mean age, 26.4±4.64 years). When the serum values of all COM patients were compared with those of the control group, in the patient group MDA, which reflects lipid peroxidation, was found to be significantly higher (P<0.01) whereas the antioxidant enzymes SOD, CAT, and GHPx were found to be significantly lower (P<0.01). When the serum and tissue MDA, SOD, CAT, and GHPx values in patients with and without cholesteatoma were compared, no significant difference was found these parameters (P>0.01). Conclusion Although oxidative stress plays a role in the pathogenesis of COM with or without cholesteatoma, it may not reflect the severity of the disease. In patients with COM, the evaluation of only serum oxidative stress values without tissue evaluation may be sufficient for assessing oxidative stress.

Objectives The purpose of the present study is to emphasize the efficacy of the myocardial performance index and tricuspid annular plane systolic excursion (TAPSE) in the determination of impaired cardiac functions and recovery period following the treatment in children with adenoid and/or tonsillar hypertrophy. Methods Fifty-three healthy children after routine laboratory, imaging and clinical examinations, with adenoid and/or tonsillar hypertrophy were evaluated before and 3 months after adenotonsillectomy for cardiac functions using M mode and Doppler echocardiography. Results The mean age of cases was 6.4±3.0 years, 34 (65%) were male, and 19 (35%) were female. Pulmonary hypertension was observed to be mild in 3 patients and moderate in 1 patient preoperatively. When the preoperative and postoperative echocardiographic measurements of the patients were compared, the tricuspid valve E wave velocity, the E/A ratio (E, early diastolic flow rate; A, late diastolic flow rate), and the TAPSE values were determined to be significantly higher postoperatively (P<0.05). The tricuspid valve deceleration time, the isovolumetric relaxation time and the systolic pulmonary artery pressure were found to be significantly lower compared to the preoperative values (P<0.05). Conclusion Adenoidectomy and/or tonsillectomy may prevent cardiac dysfunctions that can develop in the later periods due to adenoid and/or tonsil hypertrophy in children, before the appearance of the clinical findings of cardiac failure.

Mahfuz Turan; Ferhat Kalkan; Nazım Bozan; İsa Özçalimli; Mehmet Erdem; Abdülaziz Yalınkılıç; Mehmet Fatih Garca

In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a lightning strike, serious burns on the left ear, behind the ear, and on the chest and neck. She also had in her left ear 108 dB hearing loss with irregular central perforation and in her right ear 52 dB sensorineural hearing loss. There was no hearing loss before the strike. A hearing aid was recommended for the right ear and good care and follow-up were recommended for the left ear. A lightning strike can cause serious audiological damage. Therefore, it is necessary to make a careful audiovestibular evaluation of the patients. Although there exist rarely healed cases from sensorineural hearing loss after lightning strike in literature, in our case hearing loss occurred bilaterally and then it healed unilaterally. This condition is quite rare in literature.

Silent Foreign Body in Nose: Rhinolith

Mehmet Fatih Garca; Selin Fulya Guven; Nazım Bozan; Hakan Çankaya

Rhinoliths (nasal stones) are mineralized masses around a calcified nidus in the nasal cavity. The nidus may be endogenous or exogenous. It is seen in all ages and shows female predominance.Major symptoms are malodour in the nose and nasal obstruction. Rarely there is no symptom and may be diagnosed on routine examination. It seems a typically homogenous high density lesion in CT scans. Sometimes hypodensity is seen in centrally located organic material in lesions. Treatment is removal of the foreign body. For this purpose, removing the foreign body with rigid nasal endoscopy has produced succesful results. In this case we discussed a 53 year old women who had no symptoms despite having a rinolith in the left nasal cavity which fills the inferior meatus to choana. (JAREM 2012; 2: 85-6)
