The evaluation of pretreatment neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio in patients with laryngeal neoplasms

IntroductionSystemic inflammatory biomarkers are promising predictive and prognostic factors for solid cancers. The neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio are used to predict inflammation and used as biomarker in several malignancies.ObjectiveThe purpose of this study was to demonstrate the diagnostic, predictive and prognostic role of neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio in patients with laryngeal neoplasms.MethodsA retrospective study was conducted on medical records involving 229 patients with benign, premalignant and malignant laryngeal neoplasms between 2002 and 2015. The diagnostic, predictive and prognostic role of neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were evaluated using uni– and multivariate analysis.ResultsThe neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were not statistically different between patients with benign, premalignant and malignant laryngeal neoplasms. Both neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were predictive factors for stage, lymph node metastasis, and distant metastasis. Patients with high neutrophil–lymphocyte ratio value (≥4) had a poor prognosis when compared with patients with low neutrophil–lymphocyte ratio value (5 year, Overall Survival: 69.0% vs. 31.1%, p < 0.001; 5 year, disease free survival: 70.0% vs. 32.7%, p ? 0.001; 5 year, locoregional recurrence free survival: 69.7% vs. 32.0%, p < 0.001). Furthermore, neutrophil–lymphocyte ratio was an independent prognostic factor for 5 year: Overall survival (HR = 2.396; 95% CI 1.408–4.077; p = 0.001), Disease free survival (HR = 2.246; 95% CI 1.322–3.816; p = 0.006) and locoregional recurrence free survival (HR = 2.210; 95% CI 1.301–3.753; p = 0.003).ConclusionPretreatment neutrophil–lymphocyte ratio is a useful and reliable predictive and prognostic biomarker for patients with laryngeal carcinoma.

Evaluation of the predictive role of neutrophil/lymphocyte ratio in the diagnosis of lymphoma in patients with asymptomatic and ısolated cervical lymphadenopathy

IntroductionThe diagnostic approach to patients with isolated asymptomatic cervical lymphadenopathy varies between excisional biopsy and follow-up. When the anamnesis, physical examination, laboratory and imaging findings are not sufficient to identify the etiology, an excisional biopsy is performed for the differential diagnosis between early-stage lymphoma and infectious or reactive causes. If the excisional biopsy, which may have some complications, is not performed, it may delay the diagnosis of lymphoma. This diagnostic challenge could be avoided by predictive markers.ObjectivesThis study was planned to determine the predictive value of neutrophil/lymphocyte ratio in the diagnosis of Hodgkin and non-Hodgkin limphoma in patients with asymptomatic, isolated cervical limphadenopathy and underwent excisional biopsy.MethodsA total of 90 patients between the years 2016 ? 2019 admitted to our clinics due to asymptomatic isolated cervical lymphadenopathy, present in at least 4 weeks with lympho nodes in pathological dimensions persisting in the cervical region, were included to our study. An excisional lympho node biopsy was performed in all 90 patients.ResultsOf the 90 patients who underwent excisional biopsy; 34 were diagnosed as reactive lymphadenopathy 30 were non-Hodgkin linphoma, and 26 were Hodgkin linphoma. A total of 56 (62.2%) patients were diagnosed as lymphoma, either Hodgkin or non-Hodgkin, while 34 patients (38.8%) were diagnosed as reactive lymphadenopathy. The median age, total whiteblood count, neutrophil count of the lymphoma groups were significantly higher than reactive lymphadenopathy group, whereas the lymphocyte count was significantly lower in the lymphoma patients. The median neutrophil/ lymphocyte ratio was 1.7 in the reactive lymphadenopathy group, 3.5 in the non-Hodgkin limphoma group, and 3.0 in the Hodgkin limphoma group (p <  0.001).ConclusionAccording to the results of our study, neutrophil/lymphocyte ratio was significantly higher in patients who were admitted with isolated asymptomatic lymphadenopathy and were diagnosed with lymphoma, and who were diagnosed with early-stage Hodgkin and non- Hodgkin lymphoma compared to those who were found to have reactive lymphadenopathy. Neutrophil/lymphocyte ratio, which is a low-cost, fast and easy-to-access test, has a predictive value in the diagnosis of lymphoma in patients with asymptomatic lymphadenopathy.     

The systolic pulmonary artery pressure and the E/e’ ratio decrease after septoplasty in patients with grade 2 and 3 pure nasal septal deviation

IntroductionNasal septal deviation may contribute to a wide range of symptoms including nasal obstruction, headache, increased secretion, crusting, mucosal damage, and loss of taste and smell. Excessive increase in the respiratory resistance, as seen in nasal septal deviation, results in reduced lung ventilation, thereby potentially leading to hypoxia, hypercapnia, pulmonary vasoconstriction. The deformities in the nasal cavity can be associated with major respiratory and circulatory system diseases.ObjectiveTo investigate cardiovascular effects of septoplasty by comparing pre- and postoperative transthoracic echocardiography findings in nasal septal deviation patients undergoing septoplasty.MethodsThe prospective study included 35 patients with moderate and severe nasal septal deviation (mean age, 23.91 ± 7.01) who underwent septoplasty. The Turkish version of the nasal obstruction symptom evaluation, NOSE questionnaire, was administered to each participant both pre- and postoperatively in order to assess their views on the severity of nasal septal deviation, the effect of nasal obstruction, and the effectiveness of surgical outcomes. A comprehensive transthoracic echocardiography examination was performed both preoperatively and at three months postoperatively for each patient and the findings were compared among patients.ResultsMean preoperative NOSE score was 17.34 ± 1.62 and the mean postoperative score was 2.62 ± 1.68 (p = 0.00). Mean preoperative systolic pulmonary artery pressure value was 22.34 ± 4.31 mmHg and postoperative value was 18.90 ± 3.77 mmHg (p = 0.00). Mean E/e’ ratio was 5.33 ± 1.00 preoperatively and was 5.01 ± 0.90 postoperatively (p = 0.01). The NOSE scores, systolic pulmonary artery pressure values, and the E/e’ ratios decreased significantly after septoplasty (p < 0.05 for all), whereas no significant difference was found in other transthoracic echocardiography parameters (p > 0.05).ConclusionThe decrease in NOSE scores following septoplasty indicated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to nasal septal deviation may be a cardiovascular risk factor and may affect transthoracic echocardiography measurements. Moreover, the significant decrease in the systolic pulmonary artery pressure value and E/e’s ratio following septoplasty indicated that negative echocardiographic findings may be prevented by this surgery.     

The endolymphatic sac in patients with Ménière's disease: correlation between the MRI and the surgical findings

The endolymphatic sac (ES) is thought to have close relations to pathogenesis of endolymphatic hydrops. Here is reported a retrospective study of 41 patients (42 ears) with Meniere's disease who underwent MRI prior to endolymphatic sac surgery. Based on proton-density weighted image (PDI) and T2-weighted image (T2), the ES including an endolymphatic duct (ED) were estimated whether it was detectable or not. Fourteen ESs were detected on both images (Group A), 14 ESs were detected only on PDI (Group B), and the remaining 14 ESs were not detected on either image (Group D). The actual shape of the sac, obtained from surgical findings, was classified into three (normoplastic, atrophic, invisible). Seventeen ears showed normoplastic ESs and 14 showed atrophic ESs. ES was not detected in 11 ears during surgery, and these findings were compared with image classification. From the study data, normoplastic ESs tend to be observed on both images whereas atrophic or invisible sacs were hardly observed on T2. This classification of ES on MRI was thought to correlate with surgical findings and this correlation was statistically significant (Spearman's rank correlation coefficient. r(s) = 0.58, p < 0.01).     

Epithelial cells in nasal fluids from patients with allergic rhinitis: how do they relate to epidermal growth factor, eosinophils and eosinophil cationic protein?

The nasal epithelium protects the underlying tissue from damage. Epithelial cell growth is controlled by epidermal growth factor (EGF) and is possibly affected by toxic proteins, e.g. eosinophil cationic protein (ECP). The aims of this study were to examine nasal fluid epithelial cell counts and their relations to EGF, eosinophils and ECP in 23 patients with seasonal allergic rhinitis and 20 healthy controls. Nasal fluid epithelial cell counts were lower in patients than in controls. EGF levels did not differ between patients and controls, and correlated with epithelial cell counts in controls but not in patients. Eosinophils and ECP were higher in patients than in controls, but did not correlate with epithelial cell counts. The role of growth factors, such as EGF, in regulating epithelial cells merits further study.     

Prognostic role of neutrophil lymphocyte ratio and mean platelet volume in Bell’s palsy: Comparison of diabetic and non-diabetic patients

ObjectivesA low Neutrophil Lymphocyte Ratio (NLR) has been shown to be associated with good prognosis in Bell’s Palsy (BP). However, the effect of chronic diseases that may affect the NLR, including Diabetes Mellitus (DM), has not been clarified in this context. This study aimed to evaluate the relationship between NLR and Mean Platelet Volume (MPV) in BP according to whether it is accompanied by DM, and their relationship with prognosis.MethodsA prospective observational study was conducted from May 2014 to May 2020 in a tertiary referral center, of all 79 consecutive participants diagnosed with BP in department of otolaryngology and 110 consecutive healthy participants admitted to the check-up unit. Patients diagnosed with BP were divided into two groups according to whether they were diagnosed with DM: diabetic BP patients (DM-BP, n = 33) and non-diabetic BP patients without any chronic disease (nonDM-BP, n = 46). Neutrophil (NEUT) and Lymphocyte (LYM) counts, and Mean Platelet Volume (MPV) were assessed from peripheral blood samples, and the NLR was calculated. Prognosis was evaluated using the House–Brackmann Score (HBS) six months after diagnosis.ResultsThe mean NLR was 2.85 ± 1.85 in BP patients and 1.69 ± 0.65 in the control group. The mean NLR was significantly higher in BP patients than healthy controls (p < 0.001). The mean NLR was 2.58 ± 1.83 in the nonDM-BP group, 3.23 ± 1.83 in the DM-BP group, and 1.69 ± 0.65 in the control group. The NLR was significantly higher in the nonDM-BP and DM-BP groups than in the control group (p < 0.05). The recovery was 90% according to the HBS. The optimal cut-off value was 2.41 (p = 0.5).ConclusionThe NLR was increased in both diabetic and non-diabetic BP and had similar prognostic value in predicting the HBS before treatment in diabetic and non-diabetic patients with BP. MPV wasn’t significantly different in diabetic and non-diabetic BP patients compared with the normal population.     

Hyaluronan and alpha-atrial natriuretic polypeptide in human nasal polyps: contributing factors to oedema formation and polyp growth?

OBJECTIVES: To identify and localize hyaluronan (HYA) and alpha-atrial natriuretic polypeptide (ANP) in human nasal polyps and to measure the HYA concentrations. MATERIAL AND METHODS: Twelve nasal polyps were collected during routine polypectomies and processed histochemically and biochemically to determine the occurrence of HYA. The distribution of ANP was investigated using an immunocytochemical method. RESULTS: HYA was unevenly distributed, being found abundantly in the surface epithelium and basement membrane and around fibres and vessels in the lamina propria. It was also present around seromucinous glands and in the secretion of cysts in the stroma. The HYA concentration was 1,000-fold higher than in serum. ANP was abundant in the apical part of ciliated surface epithelial cells and extracellularly in the basement membrane. In the stroma, ANP was confined to apical acinar cells of the seromucinous glands. CONCLUSIONS: Osmotically active HYA and numerous ANP-immunoreactive cells, active in fluid and/or ion transport functions, are present in human nasal polyps. These substances may well be involved in oedema formation and the successive growth of nasal polyps. The high concentrations of HYA in nasal polyps may be of clinical significance for the future development of a local enzyme treatment for nasal polyposis.
