Data regarding thyroid cancer (TC) epidemiology in Greece in the last decade are scarce, so we investigated the trends in TC detection during 2007 to 2016.

We retrospectively studied 2040 pathology reports of total thyroidectomies performed at our institution from 2007 to 2016.

A number of 478 cases of TC were identified in the studied decade. The overall incidence of TC among thyroidectomies rose over the years. The proportion of papillary T1 tumors among thyroidectomies increased in the second period of our study (2012-2016), while that of papillary T2 to T4 tumors and other TC subtypes remained unchanged. Papillary T1 tumors represented 63.6% of all TC cases and 75.3% of them were low-risk microcarcinomas (papillary thyroid microcarcinoma). The strategy of fine needle aspiration (FNA) prior to surgery in the management of thyroid nodules was adopted by more clinical endocrinologists in the area of Southwestern (SW) Greece in the second period of our study (2012-201629.7% vs 2007-201118.4%,
< .001). Consequently, the indication for thyroidectomy was set by FNA more frequently in 2012 to 2016 than in 2007 to 2011 (42.5% vs 26.4% of cases,
< .001).

The wider use of FNA in the triage of thyroid nodules led to increased rates of TC in thyroidectomies performed in SW Greece during the decade 2007 to 2016; low-risk, small papillary tumors represented the majority of TC cases.

Fine-needle aspiration (FNA) of thyroid nodules suspicious for Hürthle cell neoplasms (HCN) have uncertain rate of malignancy. We aim to characterize rate and predictors of malignancy at our institution and compare these findings with established literature to help guide management.

Single tertiary-referral center, retrospective study of 166 adults who underwent hemithyroidectomy or total thyroidectomy following FNA suspicious for HCN from 1998-2018. Demographic information and surgical histopathologic results were collected. Preoperative ultrasonography was independently scored on the American College of Radiology Thyroid Imaging Reporting and Data System (TI-RADS) by a board-certified head and neck radiologist.

There were 39 males and 127 females. Overall, 25 (15.1%) patients had carcinoma, with 15 (9%) being Hürthle cell carcinoma (HCC). Men had higher incidence of carcinoma (25.6% v. 11.8%,
= .035), and especially older males. Contralateral carcinoma was seen in 3 of 13 (23.1%) patients that underwent completion thyroidectomy. Patients with carcinoma had larger nodules (average diameter 3.3 cm versus 2.5 cm, respectively,
= .01), but no association with TI-RADS.

Adults with nodules suspicious for HCN have significant risk of malignancy consistent with prior studies. Older males and larger nodule diameter are associated with malignancy in this cohort, but TI-RADS grade is not. These findings provide a framework for management and counseling for lesions suspicious for HCN.

The aim of this study was to determine the adherence to consensus guidelines on preoperative imaging of patients with primary hyperparathyroidism (pHPT) in real local practice.

This was a retrospective multicenter cohort study of 411 patients undergoing parathyroidectomy for pHPT from 2007 to 2017 in three referral centers.

In 286/411 patients (69%) the preoperative imaging workup adhered to guidelines (utilizing ultrasound and parathyroid scintigraphy). In patients in whom guidelines were followed 63% were discharged within one day versus 37% in whom guidelines were not followed (
< .0005). The use of a bimodality imaging workup, starting with ultrasound and parathyroid scintigraphy followed by imaging upscaling aiming for anatomical and functional concordance, was a predictor for the performance of a minimally invasive parathyroidectomy (OR 4.098, 95% CI 2.296-7.315,
< .0005).

The level of compliance to preoperative imaging guidelines is suboptimal in this population. Patients in whom adherence was achieved showed a shorter length of stay. More education of physicians is required regarding the appropriate preoperative imaging workup in pHPT.

Obstructive sleep apnoea is characterized by repetitive obstruction of the upper airway during sleep. click here These repeated oxygen desaturations increase cardiovascular and cerebrovascular morbidity and mortality significantly. Upper airway surgery is an option for patients who fail continuous positive airway pressure therapy. Airway collapse is usually multilevel and hypopharyngeal collapse is a challenging area to address. It is hypothesized that hyoid expansion with hyomandibular suspension can potentially increase upper airway dimensions at the hypopharynx. This study aims to document the effect of hyoid expansion using titanium plate and screws with hyomandibular suspension on hypopharyngeal airway dimensions. It is an anatomical feasibility study performed using 10 human cadaver heads.

The hyoid bone is trifractured. The expanded hyoid is then suspended to the mandible. Computed tomography (CT) scans were performed on the cadavers to measure the airway dimensions before and after the procedure.

This procedure resulted in statistically significant increase in airway dimensions at the level of the hypopharynx in all 10 human cadaver heads. Increase in cross-sectional area correlated significantly with increase in 3-dimentional (3D) volume.The mean area of the airway at the level of the hyoid increased from 999.3 ± 193.0 mm
to 1241.4 ± 103.2 mm
. Statistically significant increase in upper airway volume based on 3D reconstruction was also noted. Upper airway volume increased from 6.94 ± 6.46 mL to 13.58 ± 8.29 mL.

Airway dimensions increased with hyoid expansion and hyomandibular suspension in our cadaveric study measured using CT scans. Further studies are needed to see if this technique can be translated to clinical use in live patients.

Does nasal surgery affect multilevel surgical success outcome.

Prospective eight country nonrandomized trial of 735 obstructive sleep apnea (OSA) patients, who had multilevel palate and/or tongue surgery, divided into two groups, with or without nose surgery.

There were 575 patients in nose group, 160 patients in no nose group. The mean age for nose group 44.6 ± 11.4, no nose group 44.2 ± 11.8. Mean preoperative BMI for nose group 27.5 ± 3.6, no nose group 27.5 ± 4.1, mean postoperative BMI nose group 26.3 ± 3.7, no nose group 27.1 ± 3.8 (
= .006). Mean preoperative AHI nose group 32.7 ± 19.4, no nose group 34.3 ± 25.0 (
= .377); and mean postoperative AHI nose group 13.5 ± 10.2, no nose group 17.1 ± 16.0 (
= .001). Mean preoperative ESS nose group was 11.3 ± 4.7, no nose group was 10.4 ± 5.4 (
= .051); and mean postoperative ESS nose group was 5.3 ± 3.2, no nose group was 6.7 ± 2.8 (
= .001). The nose group had higher percentage change (adjusted for age, gender, BMI) in AHI (33.7%, 95% CI 14% to 53.5%) compared to the no nose group (
= .001); the nose group also had more percentage change in ESS (37%, 95% CI 23.6% to 50.3%) compared to the no nose group (
< .001). Change in BMI did not affect AHI nor ESS change (Cohen effect 0.03 and 0.14, respectively). AHI change in both groups were also statistically significant in the mild OSA (
= .008) and the severe OSA (
= .01). Success rate of surgery for the nose group 68.2%, while the no nose group 55.0% (
= .002).

Combining nose surgery in multilevel surgery improves surgical success.

To determine demographic and patient variables associated with nothing by mouth (NPO) violations prior to surgery in a tertiary care pediatric hospital.

A retrospective study of patients <18 years of age undergoing elective surgery at a tertiary care children's hospital from 1/1/16 to 4/30/19 who violated their NPO guidelines was performed. Variables associated with a higher rate of NPO violations were analyzed among the different surgical sub-specialties. Additional analyses were performed comparing those with NPO violations to the total group of patients undergoing surgery in the study period.

Of the 42 495 children who underwent elective surgical procedures in the study period, 625 (1.5%) committed NPO violations. The median age for those committing a violation was 3 years, and the majority (n = 421, 67.4%) were between 0 and 6 years of age. Otolaryngology patients committing NPO violations had a longer time between scheduling surgery and operative date than other surgical services (
 < .0001), but a similar time as the urology service. Otolaryngology patients had the highest number of NPO violations (n = 245, 39.2%) compared to the other surgical services, despite doing 32.4% of the total surgical cases (
 < .001). Children from Spanish-speaking homes accounted for 137 (21.9%) NPO violations, despite accounting for only 11.2% of total surgeries performed. Patients with Medicaid insurance (n = 438, 63.0%) had a higher rate of NPO violations, despite making up 43.6% of total patients.

NPO violations occurred in 1.5% of patients during the study period, particularly among the youngest age range of the children analyzed, and they were most prevalent in the otolaryngology patients. Spanish speaking families, and those with Medicaid insurance had higher rates of NPO violations despite making up a smaller percentage of those being operated on overall. This highlighted the need for improvement in communication of fasting guidelines to caregivers.

The study systematically reviewed the existing literature on the management of autoimmune inner ear disease (AIED).

Systematic review.

We performed a literature search of Embase, NCBI, Cochrane, and Web of Science databases from April 1990 to April 2020. Inclusion criteria included studies that were retrospective or prospective in nature evaluating the treatment of AIED with audiometric data measuring hearing outcomes during treatment. Hearing improvement was the primary study outcome and improvement in vestibular symptoms was the secondary study outcome.

Sixteen of 412 candidate articles were included in our study. Systemic steroid treatment is most commonly described. Alternative treatment modalities included intratympanic steroid treatment, methotrexate, cyclophosphamide, azathioprine, infliximab, etanercept, adalimumab, golimumab, methylprednisolone, rituximab, and anakinra.

Systemic corticosteroids are the first line treatment of AIED. Intratympanic steroids are a potential adjuvant or alternative treatment for patients who cannot tolerate or become refractory to steroid treatment.
