Introduction  Unplanned hospital returns are frequent and may be preventable. Objective  To comprehend the reasons for unplanned hospital readmission and return to the Outpatient Department (OPD) and Emergency Department (ED) within 60 days after discharge following head and neck surgery (HNS) at a tertiary care center in Saudi Arabia. Methods  In the present retrospective study, the medical records of all patients who underwent HNS for benign and malignant conditions between January 2015 and June 2022 were reviewed in terms of demographic data, comorbidities, and reasons for hospital return. Results  Out of 1,030 cases, 119 (11.55%) returned to the hospital within 60 days after discharge, 19 of which (1.84%) were readmitted. In total, 90 (8.74%) patients returned to the OPD, and 29 (2.82%), to the ED. The common reasons for readmission included infections (26.32%) and neurological symptoms (21.05%). For OPD visits, the common causes were hematoma (20%) and neurological symptoms (14.44%). For ED returns, the frequent causes were neurological symptoms (20.69%) and equipment issues (17.24%). Compared with nonreadmitted patients, readmitted patients had a higher preoperative baseline health burden when examined using the American Society of Anesthesiologists (ASA) score ( p  = 0.004) and the Cumulative Illness Rating Scale (CIRS; p  = 0.002). Conclusion  The 60-day rates of unplanned hospital return to the OPD and ED were of 8.74% and 2.82% respectively, and 1.84% of the patients were readmitted. Hematoma, infections, and neurological symptoms were common causes. Addressing the common reasons may be beneficial to decrease postoperative hospital visits.

Introduction  Chronic rhinosinusitis (CRS) is a common inflammatory disease. This high prevalence leads to high direct and indirect public health costs, which include medical visits, laboratory tests and imaging, pharmacotherapy, hospitalizations, and surgical treatment. Furthermore, CRS has a substantial impact on patient quality of life, affecting productivity and being a common cause of absence from work CRS-associated olfactory dysfunction is highly prevalent, the actual effectiveness of surgical intervention remains inconsistent. Although there are studies evaluating the postoperative course of patients with eosinophilic Chronic rhinosinusitis (eCRS) treated with high-volume budesonide irrigation, there is little objective information regarding the impact of this intervention on olfactory status and quality of life. Objective  To conduct a pre- and postoperative analysis of olfaction and quality of life in patients with eCRS treated with surgical intervention followed by high-volume budesonide nasal irrigation. Methods  Prospective, descriptive, uncontrolled study of patients with eCRS. All patients underwent pre- and postoperative nasal endoscopy, SNOT-22 questionnaire, and the University of Pennsylvania Smell Identification Text (UPSIT), always by the same previously trained examiner. The SNOT-22 questionnaire and the UPSIT were readministered to all patients at 3 months, 6 months, and 1 year postoperatively, and scores compared with those obtained preoperatively. Results  Twenty patients were included in the study, 13 males and 7 females, between the ages of 23 and 65; 8 patients had comorbid asthma. Quantitative evaluation using the UPSIT test showed a significant improvement in olfaction 3 months after surgery, which remained 6 months and 1 year after surgery (p = 0.0063). There was no significant association between eosinophil concentrations in polypoid tissue and postoperative SNOT-22 and UPSIT results. Patients with tissue eosinophils >50 had a lower preoperative UPSIT score. As early as 3 months postoperatively, a significant improvement in quality of life was already noticeable, as represented by a decrease in SNOT-22 values, which persisted through the 1-year postoperative follow-up evaluation (p = 0.0005). Quantitative evaluation using the UPSIT test showed a significant improvement in olfaction 3 months after surgery, which remained 6 months and 1 year after surgery (p = 0.0063). Conclusion  Surgery effectively controlled eCRS in patients who adhered to high-volume budesonide nasal irrigation postoperatively. There were significant improvements in quality of life and olfaction, which persisted at least up to one year postoperatively.

Introduction  In clinical practice, patients with the same degree and configuration of hearing loss, or even with normal audiometric thresholds, present substantially different performances in terms of speech perception. This probably happens because other factors, in addition to auditory sensitivity, interfere with speech perception. Thus, studies are needed to investigate the performance of listeners in unfavorable listening conditions to identify the processes that interfere in the speech perception of these subjects. Objective  To verify the influence of age, temporal processing, and working memory on speech recognition in noise. Methods  Thirty-eight adult and elderly individuals with normal hearing thresholds participated in the study. Participants were divided into two groups: The adult group (G1), composed of 10 individuals aged 21 to 33 years, and the elderly group (G2), with 28 participants aged 60 to 81 years. They underwent audiological assessment with the Portuguese Sentence List Test, Gaps-in-Noise test, Digit Span Memory test, Running Span Task, Corsi Block-Tapping test, and Visual Pattern test. Results  The Running Span Task score proved to be a statistically significant predictor of the listening-in-noise variable. This result showed that the difference in performance between groups G1 and G2 in relation to listening in noise is due not only to aging, but also to changes in working memory. Conclusion  The study showed that working memory is a predictor of listening performance in noise in individuals with normal hearing, and that this task can provide important information for investigation in individuals who have difficulty hearing in unfavorable environments.

Introduction  Noise obscures speech signal, causing auditory masking. The effects of this masking can be observed through the cortical auditory evoked potentials (CAEPs). White noise, in turn, has an effect on the auditory cortex, interfering, for example, with lexical decision making. Objective  To analyze the effect of simultaneous masking by contralateral white noise on CAEPs elicited by speech stimuli. Methods  Cross-sectional observational analytical study carried out with 15 participants of both sexes, who were submitted to CAEPs in two conditions: 1) without noise; 2) with white noise at 100 dBSPL intensity, contralaterally and simultaneously. To compare these conditions, the Student t test or the Wilcoxon test were used, depending on the sample normality. Differences with p values < 0.05 were considered significant. Results : When white noise was presented contralaterally and simultaneously to the CAEPs with speech stimulus, an increase in P1, N1 and P2 wave latencies was observed. P1 and P2 amplitudes and N1-P2 peak to peak amplitude also increased, unlike N1 amplitude, which decreased. The differences were significant for P1 and P2 wave latencies and for P2 wave amplitude. Conclusion  The simultaneous masking effect was observed from the morphological alterations of the CAEPs with speech stimulus when white noise was presented in the contralateral ear. There was a significant increase in P1 and P2 wave latencies, as well as in P2 wave amplitude.

Introduction  The most common postoperative complication of total thyroidectomy is hypocalcemia, usually monitored using serum parathyroid hormone and calcium values. Objective  To identify the most accurate predictors of hypocalcemia, construct a risk assesment algorithm and analyze the impact of using several calcium correction formulas in practice. Methods  A prospective, single-center, non-randomized longitudinal cohort study on 205 patients undergoing total thyroidectomy. Parathyroid hormone, serum, and ionized calcium were sampled post-surgery, with the presence of symptomatic or laboratory-verified asymptomatic hypocalcemia designated as primary outcome measures. Results  Parathyroid hormone sampled on the first postoperative day was the most sensitive predictor of symptomatic hypocalcemia development (sensitivity 80.22%, cut-off value ≤2.03 pmol/L). A combination of serum calcium and parathyroid concentration sampled on the first postoperative day predicted the development of hypocalcemia during recovery with the highest sensitivity and specificity (94% sensitivity, cut-off ≤2.1 mmol/L, and 89% specificity, cut-off ≤1.55 pmol/L, respectively). The use of algorithms and correction formulas did not improve the accuracy of predicting symptomatic or asymptomatic hypocalcemia. Conclusions  The most sensitive predictor of symptomatic hypocalcemia present on the fifth postoperative day was PTH sampled on the first postoperative day. The need for algorithms and correction formulas is limited.

Introduction  Human papillomavirus-related (HPV + ) oropharyngeal squamous cell carcinoma (OPSCC) is increasing in incidence and presents diagnostic challenges given its unique clinical presentation. Objective  The purpose of the present study is to characterize the impact of the unique clinical presentation of HPV-related OPSCC on delays in diagnosis. Methods  Retrospective review of presenting symptoms and clinical characteristics of 284 patients with OPSCC treated from 2002-2014. Delay in diagnosis was defined as the presence of any of the following: multiple non-diagnostic fine needle aspirate (FNA) biopsies; two or more courses of antibiotic therapy; surgery with incorrect preoperative diagnosis; evaluation by an otolaryngologist without further workup; or surgery without definitive postoperative diagnosis. Results  p16+ tumors demonstrated a distinct clinical presentation that more commonly involved a neck mass (85.1% versus 57.3% of p16-; p  < 0.001) and less frequently included odynophagia (24.6% versus 51.7% of p16-; p  < 0.001). Patients who experienced diagnostic delay were more likely to have p16+ tumors (77.7% delayed versus 62.8% not delayed; p  = 0.006). p16+ primary tumors were more likely to be undetectable by physical examination of the head and neck including flexible laryngoscopy (19.0% versus 6.7% of p16-; p  = 0.007) and more frequently associated with nondiagnostic FNA biopsies of a cervical nodal mass (11.8% versus 3.4% of p16-, p  = 0.03). Conclusions  Compared with non-HPV related OPSCC, the unique clinical presentation and characteristics of HPV+ OPSCC are associated with an increased incidence of diagnostic delay. Targeted education of appropriate care providers may improve time to diagnosis and treatment.

Introduction  Some common symptoms of coronavirus disease 2019 (COVID-19) are fever, cough, and shortness of breath. But ear, nose, and throat (ENT) manifestations such as loss of smell and taste are also very common. Objectives  To compare the general and otorhinolaryngological manifestations of COVID-19 and to compare the treatments given and mortality rate during its two waves. Methods  This retrospective study was conducted on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases in a tertiary care teaching hospital. Six hundred patients were included in the 1st wave sample and 516 were in the 2nd wave sample. The data collected included demographics, comorbidities, general, and ENT symptoms, need for ventilatory support, oxygen therapy, and mortality for both the waves. Results  Fever, malaise, and myalgia were more frequently presented in the first wave than in the second, whereas shortness of breath was more common in the second wave. In the second wave, a significant increase in anosmia cases was reported, whereas sore throat, nasal obstruction, dysphagia, nasal discharge, and sneezing were significantly reduced compared with the first wave ( p  < 0.001). The case fatality rate increased from 11.33 to 21.55% ( p  < 0.001) from the 1 ^st to the 2 ^nd wave. The patients who died in the second wave were younger than those in the first wave. Two doses of vaccination showed protection from the death over those not vaccinated and those who only received one dose ( p  < 0.05). Conclusion  Ear, nose, and throat (ENT) manifestations are very common along with the general symptoms. As anosmia and dysgeusia are early presenting symptoms in COVID-19 patients, all physicians should screen patients for ENT symptoms.

Introduction  Appropriate quality and quantity of sleep are critical for good mental health, optimal body functioning, memory consolidation, and other cognitive processes. Objectives  To evaluate the sleeping patterns of medical students in Saudi Arabia and their relationships with psychological distress. Methods  This was a cross-sectional, self-administered, questionnaire-based study. The study included medical students from a university in Jeddah, Saudi Arabia. The Pittsburgh Sleep Quality Index (PSQI) and the Athens Insomnia Scale (AIS) were used to evaluate the prevalence and burden of inadequate sleep quality and insomnia in the participants. Results  The majority of the participants was women (76.6%). Furthermore, most participants (96.2%) were aged between 18 and 24 years old, while 54.4% of the participants were in their senior year. According to the AIS scores (mean: 15.85 ± 4.52), 98.7% of the participants exhibited insomnia symptoms. The PSQI scores (mean: 9.53 ± 5.67) revealed that 70.5% of the participants had poor sleep quality. Students in their fundamental and junior years had significantly higher percentages of insomnia symptoms and poor sleep quality compared with students in their senior years. Conclusion  The prevalence of insomnia and poor sleep quality is high among medical students. Therefore, appropriate strategies for early detection and intervention are warranted.

Introduction  Smell is one of the senses of the human body, and it can be affected by several factors, such as viral infections, traumatic brain injury, iatrogenesis, smoking, and neurodegenerative and systemic diseases. Objectives  The main goal of the present study is to describe the epidemiology of olfactory disorders in Rio Grande do Norte (RN). More specifically, to determine the prevalence of olfactory dysfunction and to identify the main risk factors related to these dysfunctions in the state's population. Methods  A total of 180 volunteers living in the RN underwent the Connecticut Clinical Research Center (CCCRC) smell test and a clinical and demographic questionnaire. Results  A total of 58.89% of the patients presented normosmia and 87.78% were classified as having between normal and mild hyposmia. A statistically significant relationship was found between worse performance in the test and nasal surgery ( p  = 0.041) and the subjective feeling of not having an accurate sense of smell ( p  = 0.006 on the right nostril). There was no statistical relationship between the olfactory status and the report of coronavirus disease 2019 (COVID-19) infection ( p  = 0.254). Conclusion  The occurrence of altered sense of smell in our study was different from that reported in other studies that used the same test. The relationship with COVID-19 was not clear.

Introduction  The harmonic scalpel (HS) is a technique introduced to reduce blood loss and intraoperative time during neck dissection (ND). Objective  To compare the results of HS with traditional hemostasis in ND through a systematic review and metanalysis. Methods  A computer-based strategy of systematic literature survey included research in the MEDLINE, EMBASE, and Cochrane Library databases from January 2007 up to August 2022. The survey strategy employed was [harmonic scalpel OR ultrasonic scalpel] AND neck dissection. Results  There were 61 articles identified that addressed the use of HS in patients undergoing ND. From those, 10 randomized clinical trials were selected, comprising 264 cases of ND using HS and 262 cases of ND without HS. Conclusion  The use of HS for ND significantly reduces the operative time, intraoperative bleeding, volume of draining fluid, and the number of ligatures.
