RESUMO
INTRODUCTION: Patulous Eustachian tube (PET) is a condition affecting approximately 0.3% to 6.6% of the population, with autophony being the predominant complain. The management of PET lacks a well-defined standard in the literature as no effective medical treatments have been documented but various surgical options are available. This study aims to report mid-term outcomes following surgical management of PET. MATERIALS AND METHODS: All patients who underwent surgical intervention for PET between September 2017 and June 2022 were enrolled. Data encompassing general demographics, quality of life (GBI), and procedure-specific data were collected. RESULTS: A total of 30 PET cases (in 19 patients) underwent surgical intervention including 9 injections of hyaluronic acid, 13 fat injections, 6 endoscopic shim insertions, 1 cartilage graft, and 1 injection of hydroxy apatite. After an average follow-up of 22 ± 14 months, 16 cases (53%) achieved complete symptom relief, while 8 cases (26.6%) reported partial relief. Additionally, 11(36%) cases required multiple surgeries. No specific surgical technique demonstrated superiority. Quality of life improved in 77% of cases based on 10 out of 13 GBI collected. Recurrence of PET symptoms occurred on average 10.6 ± 9.7 months after initial surgery, with an estimated global risk of 75% at 3 years. Transient serous otitis media was observed in only 4 cases (13.3%). CONCLUSION: Surgical intervention for PET was found to be effective, achieving complete symptom relief in 53% of cases and significantly improving quality of life 2 years post-surgery. However, a substantial portion of cases necessitated one or more re-interventions. The durability of effectiveness appears to diminish over time.

OBJECTIVES: To translate and validate French versions of two health-related quality of life questionnaires for patients with peripheral facial palsy: Facial Disability Index (FDI) and Facial Clinimetric Evaluation (FaCE) scale. DESIGN: Prospective cohort study. SETTING: University tertiary referral centre. PARTICIPANTS: A pilot test was performed on 10 subjects (5 patients with facial palsy of more than 1-month duration and 5 normal subjects), and then 67 adult patients with facial palsy were enrolled in the validation study. MAIN OUTCOME MEASURES: Translation of the original questionnaires has followed international guidelines using a forward-backward translation method. A pilot test and a validation study based on the translated questionnaires were performed. Internal consistency, test-retest reliability, validity and responsiveness were assessed. Validity was assessed by comparing to SF-36 and Sunnybrook/House-Brackmann grading systems. Subjects answered scales twice within a one-week interval. RESULTS: Sixty-seven patients were enrolled, among which 63 completed scales one week later (retest). For physical and social functions of FDI and FaCE scores, Cronbach's α representing internal consistency was 0.88, 0.70 and 0.89, and test-retest reliability by intra-class correlation coefficients was 0.81, 0.86 and 0.89, respectively. The correlation of facial movement score of FaCE scale was good with Sunnybrook/House-Brackmann grading systems (0.73 and -0.75, P < 0.01). The correlation of social function of FaCE scale was excellent with social function of SF-36 (0.8, P < 0.01). CONCLUSIONS: French versions of FDI and FaCE scale are psychometrically valid. Both questionnaires can be used for clinical studies to assess the quality of life of patients with peripheral facial palsy.

Background: Many countries have succeeded in curbing the initial outbreak of COVID-19 by imposing strict public health control measures. However, little is known about the effectiveness of such control measures in curbing the outbreak in developing countries. In this study, we seek to assess the impact of various outbreak control measures in Kuwait to gain more insight into the outbreak progression and the associated healthcare burden. Methods: We use a SEIR mathematical model to simulate the first wave of the epidemic outbreak of COVID-19 in Kuwait with additional testing and hospitalization compartments. We calibrate our model by using a NBD observational framework for confirmed case and death counts. We simulate trajectories of model forecasts and assess the effectiveness of public health interventions by using maximum likelihood to estimate both the basic and effective reproduction numbers. Results: Our results indicate that the early strict control measures had the effect of delaying the intensity of the outbreak but were unsuccessful in reducing the effective reproduction number below 1. Forecasted model trajectories suggest a need to expand the healthcare system capacity to cope with the associated epidemic burden of such ineffectiveness. Conclusion: Strict public health interventions may not always lead to the same desired outcomes, particularly when population and demographic factors are not accounted for as in the case in some developing countries. Real-time dynamic modeling can provide an early assessment of the impact of such control measures as well as a forecasting tool to support outbreak surveillance and the associated healthcare expansion planning.

BACKGROUND: COVID-19 has a highly variable clinical presentation, ranging from asymptomatic to severe respiratory symptoms and death. Diabetes seems to be one of the main comorbidities contributing to a worse COVID-19 outcome. OBJECTIVE: In here we analyze the clinical characteristics and outcomes of diabetic COVID-19 patients Kuwait. METHODS: In this single-center, retrospective study of 417 consecutive COVID-19 patients, we analyze and compare disease severity, outcome, associated complications, and clinical laboratory findings between diabetic and non-diabetic COVID-19 patients. RESULTS: COVID-19 patients with diabetes had more ICU admission than non-diabetic COVID-19 patients (20.1% vs. 16.8%, p < 0.001). Diabetic COVID-19 patients also recorded higher mortality in comparison to non-diabetic COVID-19 patients (16.7% vs. 12.1%, p < 0.001). Diabetic COVID-19 patients had significantly higher prevalence of comorbidities, such as hypertension. Laboratory investigations also highlighted notably higher levels of C-reactive protein in diabetic COVID019 patients and lower estimated glomerular filtration rate. They also showed a higher incidence of complications. logistic regression analysis showed that every 1 mmol/L increase in fasting blood glucose in COVID-19 patients is associated with 1.52 (95% CI: 1.34-1.72, p < 0.001) times the odds of dying from COVID-19. CONCLUSION: Diabetes is a major contributor to worsening outcomes in COVID-19 patients. Understanding the pathophysiology underlining these findings could provide insight into better management and improved outcome of such cases.
RESUMO
COVID-19 is challenging healthcare preparedness, world economies, and livelihoods. The infection and death rates associated with this pandemic are strikingly variable in different countries. To elucidate this discrepancy, we analyzed 2431 early spread SARS-CoV-2 sequences from GISAID. We estimated continental-wise admixture proportions, assessed haplotype block estimation, and tested for the presence or absence of strains' recombination. Herein, we identified 1010 unique missense mutations and seven different SARS-CoV-2 clusters. In samples from Asia, a small haplotype block was identified, whereas samples from Europe and North America harbored large and different haplotype blocks with nonsynonymous variants. Variant frequency and linkage disequilibrium varied among continents, especially in North America. Recombination between different strains was only observed in North American and European sequences. In addition, we structurally modelled the two most common mutations, Spike_D614G and Nsp12_P314L, which suggested that these linked mutations may enhance viral entry and replication, respectively. Overall, we propose that genomic recombination between different strains may contribute to SARS-CoV-2 virulence and COVID-19 severity and may present additional challenges for current treatment regimens and countermeasures. Furthermore, our study provides a possible explanation for the substantial second wave of COVID-19 presented with higher infection and death rates in many countries.

OBJECTIVES: To investigate the role of ethnicity in COVID-19 outcome disparities in a cohort in Kuwait. METHODS: This is a retrospective analysis of 405 individuals infected with SARS-CoV-2 in Kuwait. Outcomes such as symptoms severity and mortality were considered. Multivariate logistic regression models were used to report the odds ratios (OR) for ICU admission and dying from COVID-19. RESULTS: The cohort included 290 Arabs and 115 South Asians. South Asians recorded significantly higher COVID-19 death rates compared to Arabs (33% vs. 7.6%, P value<0.001). When compared to Arabs, South Asians also had higher odds of being admitted to the ICU (OR = 6.28, 95% CI: 3.34-11.80, p < 0.001). South Asian patients showed 7.62 (95% CI: 3.62-16.02, p < 0.001) times the odds of dying from COVID-19. CONCLUSION: COVID-19 patients with South Asians ethnicity in Kuwait are more likely to have worse prognosis and outcome when compared to patients with Arab ethnicity. This suggest a possible role for ethnicity in COVID-19 outcome disparities and this role is likely to be multifactorial.

Background: Middle ear (ME) pressure regulation has been suggested as a physiological mechanism that maintains pressure equilibrium between the ME and the ambient environment. This mechanism would be based on a complex sensorineural reflex loop composed of mechanoreceptors, an integrative center, and efferent neural pathways. Our aim was to demonstrate that hypoxic conditions, which would inhibit mechanoreceptors in general, similarly participate in the inhibition of the opening of the Eustachian tube (ET), and thus, to suggest that such receptors are involved in the overall regulation of ME pressure. Materials and Methods: Among 14 healthy volunteers, tubomanometry was performed in normoxia followed by hypoxia, and 3 parameters were evaluated for each ear under each condition, allowing the evaluation of the reactivity of the system: ET opening latency index (R), the Index of Velum Contraction (IVC), and the latency of pressure instauration (C2-C1). Results: Hypoxia induced a significant increase in the opening latency index of ET opening, without deleterious effects on the quality (IVC) and latency (C2-C1) of soft palate contraction. Conclusions: Our study supports the theory of a sensorineural reflex loop and provides evidence for the existence of mechanoreceptors, whose function is modified by changes in oxygen partial pressure, able to collect information on pressure variations between the ME and the external environment.

This is a retrospective single-center study of 417 consecutive patients with coronavirus disease 2019 (COVID-19) admitted to Jaber Al-Ahmad Hospital in Kuwait between February 24, 2020 and May 24, 2020. In total, 39.3% of patients were asymptomatic, 41% were symptomatic with mild/moderate symptoms, 19.7% were admitted to the intensive care unit (ICU). Most common symptoms in cohort patients were fever (34.3%) and dry cough (32.6%) while shortness in breath was reported in (75.6%) of ICU admissions. Reported complications requiring ICU admission included Sepsis (68.3%), acute respiratory distress syndrome (95.1%) and heart failure (63.4%). ICU patients were more likely to have comorbidities, in comparison to non-ICU patients, including diabetes (35.4% vs 20.3%) and hypertension (40.2% vs 26.9%). Mortality rate of cohort was 14.4% and mean age of death was 54.20 years (± 11.09) and 90% of death cases were males. Chest high-resolution computed tomography for ICU cases reveled multifocal large patchy areas of ground glass opacification mixed with dense consolidation. Cases admitted to ICU showed abnormal levels of markers associated with infection, inflammation, abnormal blood clotting, heart problems and kidney problems. Mean hospital stay for asymptomatic cases was 20.69 days ±8.57 and for mild/moderate cases was 21.4 days ±8.28. Mean stay in ICU to outcome for survivors was 11.95 days ±8.96 and for death cases 13.15 days ±10.02. In this single-center case series of 417 hospitalized COVID-19 patients in Kuwait 39.3% were asymptomatic cases, 41% showed mild/moderate symptoms and 18.7% were admitted to ICU with a mortality rate of 14.4%.

The reconstruction of the columella is challenging and poorly evaluated in the literature. Our study aimed to evaluate retrospectively the different techniques used in our center and to propose an algorithm of reconstruction adapted to each patient. We report a retrospective cohort study included 18 patients (9 men and 9 women; 53 years-old in average) with columellar reconstruction treated from 1999 through 2014. Six different techniques were used: chondrocutaneous graft, nasolabial flap, paramedian forehead flap and scalping flap according to the Converse technique or the Raulo technique. Four independent plastic surgeons evaluated the aesthetic result on a 10â¯cm visual analogue scale comparing the patients' photographs before and after the reconstruction. Furthermore, we asked the patients to perform the same evaluation, and to evaluate their level of satisfaction. The mean follow-up was 4 years. Three chondrocutaneous grafts were performed to reconstruct partial defects (Surgical Evaluation (SE): 7.9, Patient Evaluation (PE): 8.3).Three bilateral nasolabial flaps (SE: 6.1, PE: 6.7), 5 paramedian forehead flap (SE: 6.9, PE: 7.3) 6 Converse scalping flap (SE: 4.9, PE: 5.4) and 1 Raulo scalping flap (SE: 6,1, PE: 6,3) were performed to reconstruct total defects exceeding the columella. The use of composite graft was the most satisfactory procedure for partial defects. Paramedian forehead flaps and Raulo scalping flap were the most satisfactory procedures for extended defects. Nasolabial flap was the most adapted procedure for patients with general anesthesia contraindication or for defects extended to the lip.
