OBJECTIVE:The etiopathogenesis of sudden sensorineural hearing loss (SSNHL) is not clearly defined. Inflammation is being emphasized in its etiology. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are the parameters that show inflammation that can be obtained easily without additional cost. In this study, we aimed at delineating the relationship between SSNHL and the inflammation markers NLR and PLR.
MATERIALS and METHODS:This study was performed with 102 patients diagnosed with SSNHL and 119 sex-and age-matched controls. All subjects in the study and the control group had their complete blood count (CBC) results, which were evaluated retrospectively to calculate NLR and PLR values. All patients underwent an audiological examination on the 1 st , 3rd, 10 th , and 30 th days of the hearing loss. All patients received 1 mg/kg IV prednisolone treatment in tapered amounts to be completed in 15 days. Based on the improvements seen in the audiograms, the patients were divided into two groups: responders and non-responders to treatment.
RESULTS:PLR and NLR values of the patient group were significantly higher than in the control group (p<0.001, p<0.001). Furthermore, patients who responded to treatment had significantly higher NLR values than those who did not respond (p=0.010).
CONCLUSION:In this study, NLR and PLR values were found to be significantly high in SSNHL patients. PLR value was investigated for the first time in the literature in SSNHL patients. NLR and PLR values are parameters that aid in the diagnosis of SSNHL. Moreover, SSNHL patients who had higher NLR values responded to the treatment better.
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.
Neutrophil to lymphocyte ratio value may be used as a novel marker that is easily administered in patients with nasal polyps and obtained with low-cost tests. New studies with larger patient series are needed for the value of PLR.
The aim of this study was to investigate the relation of serum monocyte to serum HDL cholesterol ratio with obstructive sleep apnea syndrome (OSAS). A total of 336 patients who underwent polysomnography (PSG) were included in this study. The individuals with an apnea hypopnea index (AHI) <5/h were included in the study as controls while the patients with an AHI > 5 and excessive daytime sleepiness were included in the study as OSAS patients. OSAS patients were compared with the control group for serum monocyte count, high density lipoprotein (HDL) levels, and monocyte to HDL ratio (MHR). Mild, moderate and severe OSAS subgroups were compared for the same parameters. Additionally, correlations of serum monocyte count, HDL level and MHR with other PSG parameters were analyzed. The mean MHR of control and OSAS groups were 12.90 ± 6.64 and 4.91 ± 6.98, respectively, and the difference was statistically significant ( = 0.041). Mean HDL level of the control group was 47.25 ± 13.61 mg/dL while it was 43.14 ± 13.61 mg/dL in OSAS group ( < 0.001). Comparison of OSAS subgroups for MHR and HDL levels revealed statistically significant differences ( < 0.001 and = 0.020, respectively). MHR was higher in OSAS patients compared to the controls. MHR may be a new, useful predictor for OSAS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
