The role of fine needle aspiration biopsy in deep lobe parotid tumors: Comparison of preoperative cytology and postoperative histopathologic results.

PURPOSE: Major salivary gland tumors constitute almost 3% of head and neck tumors. Tumors located exclusively in the deep lobe are not common and 20% of parotid gland tumors originate from deep lobe under the branches of the facial nerve. Accuracy of fine needle aspiration biopsy (FNAB) procedure in salivary gland tumors have been studied extensively, however there isn't any data regarding usefulness of FNAB in tumors located exclusively in deep lobe of parotid gland. In this study we aimed to assess the use of FNAB in deep lobe parotid tumors. MATERIALS AND METHODS: We retrospectively analyzed 51 patients with deep lobe parotid tumors who underwent surgery in our clinic between January 2013-December 2018. Characteristics of patients were recorded. Preoperative FNAB results and postoperative final histopathologic diagnosis were compared. Statistical analysis was performed using SPSS 24.0 was used for statistical analysis. RESULTS: The number of patients that met the inclusion criteria was 51. The mean age of patients were 49.2(14-86). In 40 (78.4) of the patients, tumor was reported as benign and in 11 (21.6) patients FNAB diagnosis was suspicious for malignancy, malignant or non-diagnostic. In final histopathologic diagnosis, 42 of the tumors were benign and 9 were malignant. The most common benign tumor type was pleomorphic adenoma which constitutes 27 of the cases (52.9%). Regarding detection of malignant disease, the sensitivity of FNAB was 90.4%, specificity was 77.7%, positive predictive value was 95%, negative predictive value was 63.6%. There was a substantial agreement between FNAB and final histopathologic diagnosis(kappa = 0,628). CONCLUSIONS: FNAB is a safe and reliable tool to evaluate deep lobe parotid tumors. It is an important part of preoperative surgical planning and can help the surgeon in patient counseling. FNAB with ultrasound guidance is recommended for deep lobe tumors.

Comparative Analysis of Lateral Pharyngoplasty and Uvulopalatopharyngoplasty Techniques With Polisomnography and Epworth Sleepiness Scales.

Snoring is caused by the vibration of structures of the oral cavity, such as the soft palate, uvula, tonsils, base of the tongue, epiglottis, and lateral pharyngeal walls. When these structures collapse and obstruct the airway, apnea occurs. Obstructive sleep apnea syndrome (OSAS) is characterized by repeated periods of upper airway obstruction, a decrease in arterial oxygen saturation, and interrupted sleep. The prevalence of OSAS is 1% to 5% in men and 1.2% to 2.5% in women. Crucial factors in deciding the surgical approach include a detailed ear-nose-throat examination, Muller maneuver, sleep endoscopy, and apnea hypopnea index scores. Accepted treatments include continuous positive airway pressure (CPAP), surgeries of the base of the tongue and/or palate, and multi-level surgeries. It, however, is important to continue to evaluate the efficacies of such procedures. The authors evaluated the outcomes of 23 patients who underwent surgery for OSAS, using preoperative and postoperative polysomnography (PSG) and the Epworth sleepiness scale (ESS). The results were compared before and after surgery. In all, 14 patients had lateral pharyngoplasty and 9 had uvulopalatopharyngoplasty (UPPP). The PSG and Epworth scale values were significantly lower in both groups, postoperatively. Patients indicated that their quality of life had improved. In conclusion, the surgeries were successful. In line with the literature, our results indicate that lateral pharyngoplasty and UPPP can be used in appropriate patients. Longer-term studies on more patients will provide more detailed information in the future.

Evaluation of exercise-induced bronchoconstriction and rhinitis in adolescent elite swimmers.

OBJECTIVE: Exercise-induced bronchoconstriction (EIB) without asthma and non-allergic rhinitis is frequently reported in athletes who are facing high-risk of airway dysfunctions such as elite swimmers. Therefore, we aimed to evaluate the effect of exercise on nasal and pulmonary functions, additionally to determine the prevalence of EIB and rhinitis in adolescent elite swimmers. METHODS: The study included 47 adolescent licensed-swimmers (26 males and 21 females) aged between 10 and 17 years old. The prevalence of asthma and allergic disease and the symptom severity scores measured before and after swimming training were assessed through an interview form which includes information related to our study goal. In addition, acoustic rhinometry was utilized to evaluate nasal airway, spirometry was utilized to evaluate EIB in accordance with standard protocols. RESULTS: Six swimmers had a history of allergic rhinitis (12.8%), while three (6.4%) had asthma. Post-swim mean forced vital capacity (FVC) was significantly higher than pre-swim FVC (p=0.019) and forced expiratory volume 1 (FEV-l)/FVC ratio was significantly lower than pre-swim FEV-l/FVC ratio (p=0.034). In addition, the prevalence of EIB was 8.5%. Moreover, level of nasal discharge statistically increased in post-swim period (p=0.003). CONCLUSION: We have documented that swimming cause's nasal discharge but do not effect nasal passages. In addition, we observed that the overall prevalence of EIB in swimmers was not different from that of the general population, furthermore swimming exercise significantly increased FVC of swimmers. Therefore, we concluded swimming training can be recommended for children diagnosed with asthma or allergic rhinitis.

Epidemiology and Clinical Features of Peritonsillar Abscess: Is It Related to Seasonal Variations?

OBJECTIVE: Peritonsillar abscess (PTA) is defined as pus accumulation between the tonsillar capsule and constrictor pharyngeal muscle. It can be seen as a complication of acute tonsillitis, but other mechanisms have also been proposed. In this study we aimed to reveal the seasonal variations and epidemiologic features of PTA. METHODS: This is a retrospective, observational study. We reviewed 221 patients, and together with 24 recurrent cases, 245 admissions were reviewed in total. Age, gender, the duration of admission, seasonal and monthly distribution of cases, diabetes and smoking status, white blood cell count, and C-reactive protein (CRP) levels were recorded. Monthly and seasonal incidences of PTA were reviewed to see if there is any association of climate variations and PTA incidence rate. Features associated with the length of hospitalization and recurrence were also analyzed. RESULTS: A total of 245 PTA cases were admitted to our clinic between June 2014 and June 2017. The highest amount of cases was observed in spring and winter. The C-reactive protein and white blood cell count (WBC) levels were found to be positively correlated with the length of hospitalization. There was no statistically significant correlation with recurrence and smoking, the WBC levels, CRP levels, and length of prior hospitalization. Diabetes status was not found to be associated with length of hospitalization and CRP levels. CONCLUSION: The present study reflects the epidemiologic and clinical features of PTA in Istanbul. Our findings showed that seasonal variation was not significant, consistent with previous studies. The highest incidence rate was observed in spring and winter. Length of hospitalization was found to be positively correlated with C-reactive protein and white blood cell count (WBC) levels. Recurrence was not statistically correlated with and smoking, the WBC levels, CRP levels, and length of hospitalization. More studies are recommended to reveal the different epidemiologic factors affecting the incidence of PTA.
