Of all smoking metrics, >20 pack-year history was the strongest predictor of both OS (HR 2.24, 95% CI 1.19-4.20) and DFS (HR 1.67, 95% CI 1.04-2.66) on univariable and multivariable analysis after adjusting for age, overall stage, and comorbidities. Patients with >20 pack-year smoking history were also more likely to have recurrence (HR 1.59, 95% CI 0.95-2.67) after adjusting for overall stage.

Heavier smoking >20 pack-years was the strongest smoking metric associated with 2-times worse survival and recurrence. Our findings suggest that >20 pack-year smoking history may be a more useful cutoff for risk stratification models but requires further validation.

To investigate the Effect of concurrent nasal surgery on the eustachian tube function (ETF) and myringoplasty outcomes for the chronic perforations with coexistent nasal pathology.

We retrospectively reviewed the records of 93 patients with perforations who underwent same-day myringoplasty and nasal-septal surgery. Group A exhibited septal deviations (n=34) and Group B inflammatory sinus disease (n=59). Groups were compared with respect to pre- and postoperative air-bone gaps (ABGs), graft success rates and ETF (Eustachian tube score [ETS] and seven-item Eustachian Tube Dysfunction Questionnaire [ETDQ-7]) at 6 and 24months.

Graft success rates were 100.0% in Group A and 98.3% in Group B at 6months postoperatively (P=0.445). Graft success rates were 85.3% in Group A and 96.6% in Group B at 24months postoperatively (P=0.046), the re-perforation rate was significantly higher in Group A than in Group B (P=0.015). Although the preoperative ETS was similar between two groups, the postoperative ETS in the Group B was significantly higher compared with Group A regardless of at postoperative 6th and 24th months. In addition, difference was significant for the patients with positive Valsalva maneuver among two groups at postoperative 24th months. Also, the improvement in the ETDQ-7 score in the B group was significantly higher than that in the A group at postoperative 6th and 24th months.

Concurrent nasal surgery and myringoplasty is feasible. In addition, ESS improves ETF and thus long-term outcomes of myringoplasty for the chronic perforations with inflammatory sinus disease.

To investigate the potential for cancer cells to be transferred between anatomic sites via instruments and other materials.

Pilot prospective study from April 2018-January 2019 at Rush University Medical Center. Glove and instrument washings were collected from 18 high-risk head and neck cancer resection cases (36 samples total). Each case maintained at least one of the following features in addition to a diagnosis of squamous cell carcinoma or sarcoma palliative/salvage surgery, positive margins, extensive tumor burden, and/or extra capsular extension (ECE). Surgical gloves and four main instruments were placed through washings for blind cytological assessment (2 samples/case).

18 patients undergoing surgical tumor resection for biopsy-proven squamous cell carcinoma with at least one of the aforementioned characteristics were included. 26.7% of cases had ECE, 40.0% had positive final margins and 46.7% had close final margins. Tumor locations included oral cavity (10), neck (4), parotid gland (2), and skin (2). Malignant cells were isolated on glove washings in 1 case (5.5%). No malignant cells were isolated from instrument washings. The single case of malignant cells on glove washings occurred in a recurrent, invasive squamous cell carcinoma of the scalp with intracranial extension. Anucleated squamous cells likely from surgeon skin were isolated from 94.4% of washings. https://www.selleckchem.com/products/loxo-195.html Squamous cells were differentiated from mature cells by the absence of nuclei.

Malignant squamous cells can be isolated from surgical glove washings, supporting the practice of changing of gloves after gross tumor resection during major head and neck cancer resections.

Thyroglossal duct cyst (TGDC) may appear in all age groups. The impact of age on surgical outcome has been reported with conflicting results. The aim of the study was to evaluate different risk factors for surgical success according to stratified age groups.

A single center retrospective study. All patients who underwent a Sistrunk procedure between 2004 and 2018 were enrolled. Data included demographics, pre-operative presentation, intra\postoperative complications and surgical failures. Population groups were divided into adults (≥18years), older children (OC, 3-18years) and toddlers (<3years).

A total of 109 patients were included 55 adults (50.5%), 36 OC (33%) and 18 toddlers (16.5%). The adult group demonstrated a significant lower rate of surgical failures when compared to the toddler (3.6%, vs. 38.9%, P<0.001, respectively) and the OC group (3.6%, vs 16.7%, P=0.032, respectively). A borderline significance was found when comparing surgical failure rates among toddlers and OC (38.9% vs.16.7%, P=0.07, respectively). Post-operative complications were associated with surgical failures among toddlers (P=0.045) and OC (P=0.016), but not adults. Pre-operative infection and admission were significantly associated with failure in the OC group.

Surgical failures following Sistrunk procedures and their associated risk factors vary between age groups. Familiarity with these rates and associations can contribute to better decision making in managing TGDC patients.
