Intranasal Schirmer Test in Allergic Rhinitis: Relationship to Symptom Scores and Role in Determining Response to Treatment.

OBJECTIVES: The Intranasal Schirmer test (INS) is an easy to administer test that can yield objective measurement of the quantity of nasal secretion and has been studied in patients with various nasal and systemic pathologies; however, the role of INS in patients with allergic rhinitis remains unclear. Our aim was to determine the relationship between various allergic symptoms and the Intranasal Schirmer Test (INS) score and to evaluate the utility of INS in determining treatment effect in patients with allergic rhinitis. METHODS: This prospective study included patients with allergic rhinitis who were randomly divided into 3 treatment groups (nasal steroid only, oral antihistamine only, nasal steroid and oral antihistamine). For all patients, Total Nasal Symptom Score (TNSS) was used to measure symptom severity and INS was administered before and after treatment. Pre-treatment and post treatment TNSS and INS scores were compared between different treatment groups and within each group. RESULTS: The study included 120 patients, with 40 patients in each group. There were significant differences both in pre-treatment and post-treatment symptom severity score with changes of INS scores between treatment groups (P < .001 and P = .002, respectively). There was a significant difference between pre-treatment and post-treatment symptom severity scores and the INS score in each treatment group (P < .001). There was also a significant positive correlation between INS score and TNSS (r = .591 and P < .001). CONCLUSION: The Intranasal Schirmer Test can be used as an objective tool for patients with allergic rhinitis as an adjunct to subjective patient symptom reports and can also be used to determine the response to treatment.

Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART).

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

Effect of Bumetanide on Facial Nerve Regeneration in Rat Model.

OBJECTIVE: We investigated the effects of bumetanide alone and in combination with dexamethasone on facial nerve regeneration in rats with facial paralysis. STUDY DESIGN: A prospective controlled animal study. SETTING: An animal laboratory. SUBJECTS AND METHODS: Facial paralysis was induced in 32 Wistar rats that we then divided into 4 groups: group 1, control; group 2, bumetanide; group 3, dexamethasone; group 4, bumetanide and dexamethasone. Electroneurography was performed 1, 2, and 4 weeks later, and nerve regeneration was evaluated by electron and light microscopy and Western blotting in week 4. RESULTS: Regarding the comparison between preoperative values and week 4, the latency difference in group 1 (1.25 milliseconds) was significantly higher than those of groups 2 to 4 (0.56, 0.34, and 0.10 milliseconds, respectively; P = .001). The latency increment in groups 2 and 3 was higher than that of group 4 (P = .002 and P = .046) in week 4, whereas groups 2 and 3 did not differ significantly (P = .291). Amplitude difference was not statistically significant from week 4 among all groups (all P > .05). The number of myelinated axons was significantly higher in all treatment groups than in the control group (P = .001). Axon number and intensity were significantly higher in group 4 as compared with groups 2 and 3 (P = .009, P = .005). CONCLUSION: After primary neurorrhaphy, dexamethasone and bumetanide alone promoted nerve recovery based on electrophysiologic and histologic measures. Combination therapy was, however, superior.

Influence Disease Activity on Voice and Laryngeal Findings of Rheumatoid Arthritis Patients.

OBJECTIVES: To reveal and to compare the voice pathologies and the detectable laryngeal findings in different phases of rheumatoid arthritis (RA). STUDY DESIGN: Prospective clinical study. METHODS: Sixty-seven consecutive patients with RA, followed up at our Physical Therapy and Rehabilitation Clinic, were included in the study. Disease activity indices of patients were calculated with Disease Activity Score-28 Index. With Voice Handicap Index (VHI), patients answered 30 questions of functional, physical, and emotional aspects. Videolaryngostroboscopy was performed by the same physician for all patients with a 70° rigid telescope (Karl Storz, Tuttlingen, Germany), and then acoustic voice analysis (PRAAT program) was performed. Reflux Finding Score was used in evaluating the laryngopharyngeal reflux. RESULTS: Posterior comissure hypertrophy (25.3%) and hyperemia/edema in arytenoid mucosa (22.3%) were detected as the most frequent findings. Other common findings were thick endolaryngeal mucus, vocal cord varices. Twenty-two patients had reflux findings (32.8%). Fundamental frequency, shimmer, maximum phonation time and VHI value were not significantly different between active and remission phases of the disease (P > 0.05). In remission phase, the jitter value and the noise to harmonic ratio value were significantly higher (P < 0.05) than active phase of the disease (P < 0.05). Abnormal laryngeal findings are higher in active phase (28% in remission phase, 54% in active phase). The mean VHI score of patients in remission phase was lower than that in active phase. CONCLUSION: RA should be included in the differential diagnosis of patients with voice disorders. Nonspecific pathologies are more prevalent in the picture. There are more objective findings and subjective complaints of patients in active phase of the disease than in the remission phase.

Which imaging modality in cochlear implant candidates?

PURPOSE: There is no guideline or consensus on preoperative radiologic imaging modality despite the fact that it has a vital importance in appropriate candidacy selection of cochlear implantation. We aimed to find out the role of high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) on surgical planning, intraoperative technique in cochlear implant candidates. METHODS: The clinical charts, imagings, and operative reports of patients who underwent cochlear implant surgery at a tertiary institution were retrospectively examined. RESULTS: 611 patients (503 children and 108 adult) were enrolled into the study. We found 11 different pathologies in MRI which could not be seen in HRCT. However, we decided the side of surgery according to MRI in only three of them in which the pathology was cochlear nerve hypoplasia. Two patients with cochlear nerve hypoplasia were children with prelingual deafness and one was adult with perilingual deafness. Moreover, we changed the surgical planning of side according to both imaging modalities in nine patients. Seven of them were children and two were adult. One of these adults had cochlear anomaly, and another had bilateral temporal bone fracture. CONCLUSIONS: We suggest both imaging modalities in pediatric candidates. However, in adults, we think that superiority of either imaging modalities is still contradictive. We had only three adult patients and the decision of the side of surgery was made according to MRI in one of them and to both imaging modalities in the other two adults.

Predictive Role of Ki-67 and Proliferative-Cell Nuclear Antigen (PCNA) in Recurrent Cholesteatoma.

OBJECTIVES: To investigate the potential use of Ki-67 and pronuclear cell antigen (PCNA) as indicators of recurrent cholesteatoma. MATERIAL AND METHODS: Patients who had been diagnosed with cholesteatoma and who had undergone canal wall-down mastoidectomy were included in this study. Subjects were divided into two groups: recurrent and non-recurrent (i.e., cases without recurrence for at least 2 years). Ossicular pathologies were recorded. Histopathologic specimens were stained for Ki-67 and PCNA and the percentages of stained cells were calculated. RESULTS: Neither group demonstrated a significant difference in terms of total Ki-67 per cell, Ki-67-stained cell counts, Ki-67-staining percentages, total PCNA per cell, PCNA-stained cell counts, or PCNA-staining percentages (p>0.05). No significant relationship was noted between the staining percentages for either Ki-67 or PCNA and the incudostapedial involvement (p>0.05); however, a significant relationship was noted between Ki-67 staining and malleus involvement (p<0.05). CONCLUSION: Although the recurrent and non-recurrent cholesteatoma groups showed no significant differences in terms of the percentages of stained cells for either Ki-67 or PCNA, we detected high Ki-67 staining in the malleus involvement group. We concluded that cell-proliferation markers could not be defined as indicators of recurrence of cholesteatoma, but they could be defined as indicators of destructive patterns of this disease.

Computed tomography analysis of intranasal distance of frontal and sphenoid sinus ostiums in children.

PURPOSE: Pediatric population may be more prone to complications in comparison to adults because of the variability of developmental changes of paranasal sinuses and skull base. Knowledge of standard columellar distances regarding age in addition to anatomical landmarks is an important guide during functional endoscopic sinus surgery. We aimed to identify standard distances from columella and anterior nasal spine to the anterior and posterior border of frontal and sphenoid sinus ostiums and provide an objective reference graph in regard to age in children. METHODS: Subjects who are older than 1 year and younger than 18 years who had undergone a head-and-neck, maxillofacial or temporal bone region high resolution computed tomography scan during the last 3 years were obtained from radiological database. The distances from columella and anterior nasal spine to the anterior and posterior border of frontal and sphenoid sinus ostiums were measured and nasofrontal and nasosphenoid angles were calculated. RESULTS: A total number of 119 children (73 boys, 46 girls) were reviewed. The average age was 7.7 ± 5.0 years. All subjects had normal sinonasal anatomy. We found statistically significantly positive correlation between age and all distances (p < 0.001). Although all measured distances of boys were greater than girls, this difference did not reach statistical significance. Additionally, nasosphenoidal angles were significantly obtuse in boys (p < 0.05). CONCLUSIONS: Our columellar distance graphic can provide further improvement of surgeon confidence while performing endoscopic sinus surgery or skull base surgery.

Relationship between vertebral artery blood flow in different head positions and vertigo.

OBJECTIVE: To identify the vertebral artery blood flow in different head positions in patients with positional vertigo with no specific diagnosis. METHODS: Patients with history of vestibular symptoms associated with changes in head position were enrolled into the study. Healthy volunteers were evaluated as control group. Doppler ultrasonography examination of the cervical segment of the vertebral arteries was performed under three different head positions: (i) supine position, (ii) head hyperextended and rotated to the right side and (iii) head hyperextended and rotated to the left side. RESULTS: In the study group, right and left vertebral artery blood flow was significantly lower in the ipsilateral hyperextended position compared to standard supine position (respectively p = .014; p = .001), but did not differ significantly when compared between the standard supine and contralateral hyperextended positions (respectively = .959; p = .669). In the control group, left and right vertebral artery blood flow did not differ significantly when the head was hyperextended to the right or left sides compared to standard supine position (p > .05). CONCLUSIONS: Our data demonstrated that the etiology of vestibular complaints in patients with undiagnosed positional vertigo might be related to impairment in vertebral artery blood flow according to head positions.

Adaptation and validation of the Turkish version of the Nasal Obstruction Symptom Evaluation scale.

BACKGROUND: The Nasal Obstruction Symptom Evaluation (NOSE) scale is a questionnaire used to assess the quality of life in patients with nasal obstruction. The aim of this study was to validate the Turkish translation of the NOSE questionnaire. METHODS: The NOSE questionnaire was translated into Turkish and then back to English. Fifty patients with septal deviation leading to nasal obstruction and 50 healthy subjects without any nasal complaints and pathologies were recruited into the study. The Cronbach α was used to test internal consistency. The Mann-Whitney U test was used to compare the NOSE scores of the 2 groups. Psychosomatic features (reliability, repeatability, validity, responding) were evaluated by concerning the criteria as test-retest procedure, self consistency, within-score and inter-score correlation and sensitivity of responding between the 2 groups. RESULTS: There was no statistically significant difference between patients and healthy subjects in terms of age, gender, and body mass index. Test-retest results among control subjects also did not demonstrate significant difference and the Cronbach α value of the NOSE scale was found to be 0.966. There was a positive correlation among every question of the NOSE scale and it was statistically significantly different from the control group. Total scores of the NOSE scale were significantly higher than the control group. CONCLUSION: The Turkish version of the NOSE scale is a valid tool for assessing patients with septal deviation and measuring the subjective severity of nasal obstruction.

The effectiveness of platelet-rich plasma in an anosmia-induced mice model.

OBJECTIVE: In this study, we aimed to functionally and morphologically demonstrate the effectiveness of platelet-rich plasma (PRP) on anosmia in a mouse model of anosmia. STUDY DESIGN: Animal study. METHODS: A total of 16 male mice were included. When selecting the mice, the food-finding test (FFT) was used to make sure that the animals could smell, and anosmia was induced by administration of intraperitoneal 3-methylindole. The mice were randomly divided into two groups of eight (groups A and B). After 1 week, topical PRP was administered to the mice in group A and topical saline was administered to the mice in group B. The FFT was again administered at 7, 14, and 21 days. The mice were sacrificed on day 21, the olfactory neuroepithelium was histopathologically examined, and the epithelial damage scores and epithelial thickness were measured. RESULTS: After topical administration of PRP and saline, the difference in the average FFT values of the groups was statistically significant at 7, 14, and 21 days (P < 0,005). During the histopathological examination, the epithelial damage score was statistically significantly lower in the PRP group (P = 0.001) than in the saline group, and epithelial thickness was statistically significantly greater in the PRP group compared to the saline group (P = 0.003). CONCLUSION: We showed that PRP administration has a curative effect on olfactory functions in an anosmia-induced mice model. However, there is a need for further research before PRP can be considered for use in patients with anosmia in clinical practice. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:E157-E162, 2018.

The seroprevalence of hepatitis B, hepatitis C, and human immunodeficiency virus in patients undergoing septoplasty.

INTRODUCTION: Worldwide, hepatitis B virus, hepatitis C virus, and human immunodeficiency virus are major health problems. Healthcare workers are at risk of transmitting blood-borne viruses, and surgeons have a higher risk of exposure to blood and higher rates of percutaneous injury than other healthcare workers. Septoplasty is among the 3 most commonly performed otolaryngological surgeries worldwide. OBJECTIVE: To determine the seroprevalence of Hepatitis B surface antigen, Hepatitis C virus antibody, and Human Immunodeficiency Virus antibody in patients undergoing septoplasty with and without turbinate surgery under general anesthesia, and to determine if preoperative testing should be performed in such patients. METHODS: This retrospective cross-sectional study included 3731 patients that underwent septoplasty with and without turbinate surgery between January 2005 and July 2015. HBsAg, anti-HCV, and anti-HIV seropositivity in the patients was evaluated retrospectively. RESULTS: Mean age of the patients was 36 years (range: 11-81 years). In all, 117 (3.6%) patients were positive for HBsAg, 12 (0.3%) were positive for anti-HCV, and 7 (0.2%) were positive for anti-HIV. CONCLUSIONS: Education of healthcare workers combined with routine preoperative serological testing in patients undergoing septoplasty under general and local anesthesia are needed to increase awareness of hepatitis B and C, and HIV infection among healthcare workers and patients in order to decrease the transmission rate.
