A study to investigate the relationship between difficult intubation and prediction criterion of difficult intubation in patients with obstructive sleep apnea syndrome

Background and Aim: Obstructive sleep apnea (OSA) syndrome is predisposed to the development of upper airway obstruction during sleep, and it poses considerable problem for anesthetic management. Difficult intubation (DI) is an important problem for management of anesthesia. In this clinical research, we aim to investigate the relationship between DI and prediction criteria of DI in cases with OSA. Materials and Methods: We studied 40 [OSA (Group O, n = 20) and non-OSA, (Group C, n = 20)] ASA I-II, adult patients scheduled tonsillectomy under general anesthesia. Same anesthetic protocol was used in two groups. Intubation difficulties were assessed by Mallampati grading, Wilson sum score, Laryngoscopic grading (Cormack and Lehane), a line joining the angle of the mouth and tragus of the ear with the horizontal, sternomental distance, and tyromental distance. Demographic properties, time-dependent hemodynamic variables, doses of reversal agent, anesthesia and operation times, and recovery parameters were recorded. Results: Significant difference was detected between groups in terms of BMI, Mallampati grading, Wilson weight scores, Laryngoscopic grading, sternomental distance, tyromental distance, doses of reversal agent, and recovery parameters. Conclusion: OSA patient′s DI ratio is higher than that of non-OSA patients. BMI Mallampati grading, Wilson weight scores, Laryngoscopic grading, sternomental distance, and tyromental distance evaluation might be predictors for DI in patients with OSA

Pretreatment Neutrophil- Lymphocyte Ratio in Salivary Gland Tumors Is Associated with Malignancy

WOS: 000389146500012PubMed: 27436419Objective. To assess pretreatment levels in the counts and percentages of leukocytes and the neutrophil-lymphocyte ratio (NLR) in benign and malignant salivary gland tumors (SGTs) while investigating whether NLR is an inflammatory marker for distinguishing low-from high-grade parotid gland tumors. Study Design. Case series with chart review. Setting. Tertiary referral center. Subjects and Methods. This study was performed on 182 patients with SGTs (age range: 16-87 years; 93 male and 89 female) who were treated between January 2010 and May 2015. Pretreatment counts and percentages of leukocytes and NLR were measured preoperatively in benign and malignant tumors. Results. Mean neutrophil percentage (63.50% +/- 12.11% vs 58.76% +/- 8.20%, P =.008) and NLR (3.29+/-3.13 vs 2.13 +/- 1.26, P =.008) were significantly higher in patients with malignant SGTs than in patients with benign SGTs. Mean lymphocyte count (2.42+/-0.72 10(3)/mm(3) vs 1.97+/-0.87 10(3)/mm(3) , P<.001) and percentage (30.67%+/-7.68% vs 26.86%+/-10.15%, P =.011) were lower in patients with malignant SGTs than in patients with benign SGTs. Mean lymphocyte percentage and NLR were significantly different between low-and high-grade malignant parotid gland tumors (P =.026 and P =.030, respectively). Conclusion. Elevated NLR could be an inflammatory marker to distinguish low-from high-grade malignant parotid gland tumors

Small cell neuroendocrine carcinoma of the posterior tongue.

In the head and neck mucosa, neuroendocrine carcinomas of the oral cavity is rare. Herein, we present the first report of a small cell neuroendocrine carcinoma in a 54-year-old man on the right lateral posterior tongue. It is important to remember that although neuroendocrine small cell carcinomas (SCCs) are most commonly seen in the lung, they rarely may arise in the extrapulmonary sites, including salivary glands, as well. As there is not any standard therapeutic regimen already existing, it is important to be aware of and to know how to deal with such rare cases

The basaloid variant of squamous cell carcinoma of the larynx

INTRODUCTION: Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma (SCC). Because of its rarity, both clinical and prognostic features of this variant are not well known. OBJECTIVE: In this study, we aimed to determine the frequency of BSCC and other SCC variants among all laryngeal SCC cases, and to determine clinical and prognostic features of BSCC variant. Study design: retrospective cohort study. Evidence level: Level 2b. MATERIAL AND METHODS: Records of the patients who had laryngeal SCC surgically treated at our institute between 2007 and 2013 were retrospectively reviewed. RESULTS: Among 198 subjects who had laryngeal SCC surgically treated, the frequency of the variants of SCC other than classical variant was 10.1% (20/198). The most common SCC variant was BSCC (6.6%). Eleven (84.6%) patients with BSCC were at an advanced stage at the presentation (p > 0.05). The 3-year overall survival and disease-free survival rates were 63% and 53% respectively. CONCLUSION: BSCC variant may be more common than previously reported. Since almost the half of patients experiences disease recurrence in the early period, multimodal treatment strategies should be employed at initial treatment, and a close follow-up is strongly recommended for this aggressive SCC variant

Expression profiles of CD11b, galectin-1, beclin-1, and caspase-3 in nasal polyposis

Background/aim: Nasal polyposis is a chronic inflammatory disease affecting the paranasal sinuses and nasal mucosae. It is thought that genetic and molecular mechanisms in inflammatory and apoptotic pathways are the main factors in the etiopathogenesis of nasal polyposis. The aim of this study was to investigate the expression patterns of CD11b, galectin-1, beclin-1, and caspase-3 in nasal polyps. Materials and methods: The mRNA expression levels of CD11b, galectin-1, beclin-1, and caspase-3 protein and western blot analysis of caspase-3 protein were evaluated in inferior turbinate mucosae and nasal polyp tissues. Results: CD11b expression was markedly higher in nasal polyp tissues when compared to turbinate mucosae (5.5 times higher, P < 0.05). Expression of galectin-1 was not statistically higher in nasal polyp tissues when compared to the controls. Beclin-1 expression in nasal polyp tissues was lower than in controls (17 times lower, P < 0.05). Caspase-3 expression was significantly lower in nasal polyp tissues than in controls (5.5 times lower, P < 0.05). Conclusion: Inflammation, apoptosis, and hyperproliferation are the major cellular processes in nasal polyposis and these proteins may take part and play some important roles in formation of this disease and the targeting of new treatment protocols

Isolated sphenoid sinus pathologies: a series of 40 cases

Background/aim: Isolated sphenoid sinus-derived lesions are rare and generally present with unclear symptoms. We are sharing our experience to be mindful of such lesions in differential diagnosis and to help accomplish successful treatment while avoiding revisions and complications. Materials and methods: Data from patients who underwent isolated sphenoid sinus surgeries (ISSs) were retrospectively extracted from the period of January 2005 to August 2015. Demographic data, chief complaints and presenting symptoms, imaging findings, surgical management, and results were evaluated. Results: There were 40 patients who underwent ISS. These patients had different pathologies. The chief complaint was nonspecific headache, except for cerebrospinal fluid leak patients who presented with serous rhinorrhea. Conclusion: It is critical to investigate suspicious symptoms with clinical findings and imaging techniques to avoid late diagnoses of isolated sphenoid pathologies. The transnasal approach is more minimally invasive and tissue-sparing. In our experience, we have noted that excising the inferior one-third of the superior turbinate decreases revisions. On the other hand, results show that the presence of concomitant pathology and invasive fungal disease increases the risk of revision surgery and complications

Failure of Concurrent Chemoradiotherapy for Organ Preservation in Laryngeal Cancer: Survival Outcomes and Recurrence Patterns

Although definitive chemoradiation (CRT) has been used for locally advanced laryngeal cancer for more than 2 decades, studies focusing on CRT failures in advanced laryngeal cancer are scarce. In this study, we aimed to determine the failure patterns and the survival outcomes in the patients who had recurrence after concurrent CRT for laryngeal cancer. Clinical records of the patients who had definitive concurrent CRT for laryngeal cancer between 2001 and 2014 at a tertiary referral center were reviewed. The end points of the study were 1-, 2-, and 3-year overall survival (OS) and disease-specific survival (DSS). In our results, there were 48 failures and the mean time period from the first diagnosis of disease to the diagnosis of recurrence was 18.0 months (range 2-72; standard deviation: 15.6). The most common recurrence pattern was local recurrence in 21 (47.9\%) patients followed by regional recurrence in 11 (22.9\%) patients. The 1 and 3 years OS rates were 41.7\%, and 19.2\% for the entire cohort, and 64.5\%, and 29.7\% for the patients who had not systemic recurrence at presentation of recurrence, respectively. The 1 and 3 years DSS rates were 43.5\%, and 20.0\% for the entire cohort, and 69.0\%, and 31.8\% for the patients who had not systemic recurrence at presentation of recurrence, respectively. All patients who had systemic recurrence initially (n = 13) died within 9 months (median = 4 months, range: 1-9 months). This study reveals that survival outcomes are unfavorable in the CRT failures and careful patient selection is critical to minimize failures. In the presence of systemic recurrence, disease course is aggressive
