Knowledge and Attitudes of Obstructive Sleep Apnea among Jordanian Otolaryngologists: A Cross-Sectional Study.

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder that affects almost one billion individuals worldwide. An estimated 16.8% of adults in Jordan have been diagnosed with OSA. Given the importance of management of OSA by otolaryngologists, we assessed the knowledge and attitudes of Jordanian otolaryngologists in managing OSA in adult and pediatric patients. A survey, conducted anonymously online, was sent present otolaryngology residents and specialist in Jordan, in the English language. The participants were given the OSA Knowledge and Attitude questionnaire (OSAKA, OSAKA-KIDS), which have been previously validated. Data were obtained and then analyzed via SPSS software. A total of 140 residents and specialist of otolaryngology were selected. A significant difference in OSAKA scores were found between otolaryngologists under 30 years of age and those above, with higher scores for the older age group. The proportion of specialists who 'agreed' or 'strongly agreed' they are confident in their ability to manage patients with OSA was significantly higher that junior residents (73.8% vs 33.3%; p = 0.008). More than 10 years at practice was associated with statistically significant higher levels of knowledge towards OSAKA scale (AOR = 0.09; p = 0.044). Additionally, being a senior resident was significantly associated with more knowledge towards OSAKA-KIDS scale (AOR = 0.19; p = 0.03). Otolaryngology residents and specialists' knowledge of OSA was very good. Further improving in the level of the knowledge toward OSA among the otolaryngology resident doctors should be implemented as possible by following the updated guidelines for the diagnosis and management OSA.

Transglabellar resection of frontal sinus cholesterol granuloma extending cranially through cecum foramina: Technical note.

Background: Cholesterol granuloma (CG) commonly occurs in the petrous apex; their occurrence in the anterior cranial fossa CGs is rare. Subfrontal approaches are the conventional surgical approaches for the resection of midline lesions of the anterior cranial fossa and frontal sinuses. In this article, we describe a successful minimally invasive approach for resection of a small midline anterior cranial fossa CG. Methods: We report a rare case of frontal air sinus CG extending intradurally through the foramen caecum. The surgical management of this patient involved the use of a minimally invasive transglabellar approach and a butterfly incision and the patient outcomes at 1 year after the surgery. Results: The lesion was totally resected with no complications and the patient was discharged on the 3rd postoperative day. A 1-year follow-up scan showed neither residual nor recurrence of the lesion. Conclusion: The transglabellar approach through a butterfly incision offers a safe approach for the resection of a lesion extending from the frontal air sinuses to the anterior cranial fossa with no complications, shorter hospital stay, and good cosmetic results.

Morphometric Analysis of the Sella Turcica and Sphenoid Sinus: A Retrospective Cross-Sectional Study / Análisis Morfométrico de la Silla Turca y Seno Esfenoidal: Un Estudio Transversal Retrospectivo

SUMMARY: This study evaluated the effects of ethnicity, sex, and age on the linear dimensions of the sella turcica (ST) and the pneumatization patterns of the sphenoid sinus (SS). In this cross-sectional retrospective study, we examined digitally standardized computed tomography scans of 100 Jordanians. These study participants comprised 50 men and 50 women, and their age ranged from 23 years to 77 years. We assessed linear ST dimensions and SS pneumatization patterns and correlated this data to age and sex. Furthermore, we compared the data with different ethnic groups from previous studies. The mean (standard deviation [SD]) length, diameter, width, and depth of the ST were 9.98 (1.89) mm, 12.45 (2) mm, 11.96 (1.76) mm, and 8.38 (1.63) mm, respectively. The mean (SD) interclinoid diameter was 8.84 (2.03) mm. These measurements were not significantly correlated with sex or age. With regards to pneumatization patterns of the sphenoid sinus, the conchal type was observed in 2 % of the study participants. Presellar involvement was observed in 30 % of the patients. The sellar and postsellar type was observed in 66 % and 2 % of patients, respectively. In our study, ST measurements did not differ significantly between the sexes. Pneumatization patterns of the SS differed from the patterns reported for other races. The findings of this study could assist neurosurgeons, orthodontists, and forensic medical investigators in diagnosing and planning treatment for pituitary gland pathologies.

Este estudio evaluó los efectos de la etnia, el sexo y la edad sobre las dimensiones lineales de la silla turca y los patrones de neumatización del seno esfenoidal (SE). En este estudio retrospectivo transversal, examinamos tomografías computarizadas estandarizadas digitalmente de 100 jordanos. Los participantes del estudio comprendían 50 hombres y 50 mujeres entre los 23 y los 77 años de edad. Evaluamos las dimensiones lineales del SE y los patrones de neumatización del SE y correlacionamos estos datos con la edad y el sexo. Además, comparamos los datos con diferentes grupos étnicos de estudios previos. La media (desviación estándar) de la longitud, el diámetro, el ancho y la profundidad del SE fueron 9,98 (1,89) mm, 12,45 (2) mm, 11,96 (1,76) mm y 8,38 (1,63) mm, respectivamente. El diámetro interclinoideo medio era de 8,84 (2,03) mm. Estas medidas no se correlacionaron significativamente con el sexo o la edad. Con respecto a los patrones de neumatización del seno esfenoidal, el tipo conchal se observó en el 2 % de los participantes del estudio. Se observó afectación preselar en el 30 % de los pacientes. El tipo selar y postsillar se observó en el 66 % y el 2 % de los pacientes, respectivamente. En nuestro estudio, las medidas del SE no difirieron significativamente entre los sexos. Los patrones de neumatización de la silla turca diferían de los patrones informados para otras razas. Los hallazgos de este estudio podrían ayudar a los neurocirujanos, ortodoncistas e investigadores médicos forenses en el diagnóstico y el tratamiento de las patologías de la hipófisis.

Radiological morphometric study of the hyoid bone using three-dimensional computed tomography (3D-CT) scans / Estudio morfométrico radiológico del hueso hioides mediante tomografía computarizada tridimensional (3D-CT)

SUMMARY: Hyoid bone measurements have been proposed to vary between different genders and age groups. The aim of the study is to study hyoid morphometrics among Jordanian patients. 3D-CT scans of 637 patients were analyzed. Ten parameters of hyoid bone were measures, including the anteroposterior length, length of greater horns (right and left), height of greater horns (right and left), width of hyoid body, height of hyoid body, the distance between the midpoints of the posterior ends of the greater horns of the hyoid bone, the angle between right and left greater horns, and the distance of the hyoid bone to the vertebral column. Also, vertebral level, fusion rank, morphology of hyoid body lingula, and shape of hyoid bone were documented. All hyoid dimensions were longer in males, but greater horns angle was wider in females. In patients younger than 30 years, the parameters are the smallest with the widest angle. The distance from hyoid to vertebral column is higher in males (30-49) years of age. No fusion between hyoid body and greater horns was observed in patients younger than 10 years, but fusion (unilateral or bilateral) was found in only 73.2 % of patients ≥ 70 years. The hyoid was mostly at vertebra C3 level and "U" shaped. The lingula shape was mostly "Scar" in males (especially ≥ 50 years) and "Nothing" in females (especially < 50 years). The maximum growth of hyoid dimensions is before age of 30 years. Fusion between hyoid body and greater horns was not seen in patients younger than 10 years. Otherwise, the hyoid features failed to predict age or gender in our sample. Furthermore, 3D-CT scan is an excellent tool to assess the anatomy of head and neck region.

Se ha propuesto que las medidas del hueso hioides varían entre los diferentes sexos y grupos de edad. El objetivo del estudio fur estudiar la morfometría del hueso hioides en pacientes jordanos. Se analizaron tomografías computarizadas en 3D de 637 pacientes. Se midieron diez parámetros del hueso hioides, incluyendo la longitud anteroposterior, la longitud de los cuernos mayores (derecho e izquierdo), la altura de los cuernos mayores (derecho e izquierdo), el ancho del cuerpo hioides, la altura del cuerpo hioides, la distancia entre los puntos medios de los extremos posteriores de los cuernos mayores del hueso hioides, el ángulo entre los cuernos mayores derecho e izquierdo, y la distancia del hueso hioides a la columna vertebral. Además, se documentaron el nivel vertebral, el rango de fusión, la morfología de la língula del cuerpo hioides y la forma del hueso hioides. Todas las dimensiones del hioides fueron más largas en los hombres, pero el mayor ángulo de los cuernos fue más ancho en las mujeres. En pacientes menores de 30 años, los parámetros son los más pequeños con el ángulo más amplio. La distancia del hioides a la columna vertebral es mayor en el sexo masculino (30-49) años. No se observó fusión entre el cuerpo hioides y los cuernos mayores en pacientes menores de 10 años, pero se encontró fusión (unilateral o bilateral) en solo el 73,2 % de los pacientes ≥ 70 años. El hioides estaba mayormente al nivel de la vértebra C3 y en forma de "U". La forma de la língula era mayoritariamente "Cicatriz" en los hombres (especialmente ≥ 50 años) y "Nada" en las mujeres (especialmente < 50 años). El máximo crecimiento de las dimensiones del hioides es antes de los 30 años. La fusión entre el cuerpo hioides y los cuernos mayores no se observó en pacientes menores de 10 años. No obstante, las características del hueso hioides no pudieron predecir la edad o el sexo en nuestra muestra. Además, la tomografía computarizada 3D es una herramienta excelente para evaluar la anatomía de la región de la cabeza y el cuello.

Prevalence of SARS-COV-2 and other respiratory pathogens among a Jordanian subpopulation during Delta-to-Omicron transition: Winter 2021/2022.

Acute respiratory tract infections (ARTIs) during the winter months are associated with higher morbidity and mortality compared to other seasons of the year, with children below five, elderly, and immunocompromised patients being the most susceptible. Influenza A and B viruses, rhinovirus, coronaviruses, respiratory syncytial virus, adenovirus, and parainfluenza viruses, are the most frequently identified causes of viral ARTIs. In addition, the emergence of SARS-CoV-2 in 2019 provided an additional viral cause of ARTIs. The aim of this study was to provide an overview of the epidemiological status of upper respiratory infections, their main causative agents, and reported clinical presentation in the winter months of 2021, during two important surges of COVID-19 in Jordan. Nasopharyngeal samples were collected from 339 symptomatic patients during the period from December 2021 to March 2022, followed by nucleic acid isolation using a Viral RNA/DNA extraction Kit. The causative virus species associated with the patient's respiratory symptoms was determined utilizing a multiplex real-time PCR targeting 21 viruses, 11 bacteria, and a single fungus. SARS-CoV-2 was identified in 39.2% of the patients (n = 133/339). A total of 15 different pathogens were also identified as co-infections among these 133 patients (n = 67/133). SARS-CoV-2-Bacterial coinfections (37.6%, n = 50/133) were the most frequent, with Bordetella species being the most common, followed by Staphylococcus aureus, and H.influenzae type B. Viral coinfection rate was 27.8% (n = 37/133), with Influenza B virus and Human bocavirus being the most common. In Conclusion, Both SARS-CoV-2, influenza B virus, and Bordetella accounted for the majority of infections in patients with URTI during the winter months of 2021-2022. Interestingly, more than 50% of the patients with symptoms of URTIs were confirmed to have a coinfection with two or more respiratory pathogens, with SARS-CoV-2 and Bordetella coinfection being most predominant.

Immunoglobulins response of COVID-19 patients, COVID-19 vaccine recipients, and random individuals.

BACKGROUND: The development of specific immunoglobulins to COVID-19 after natural infection or vaccination has been proposed. The efficacy and dynamics of this response are not clear yet. AIM: This study aims to analyze the immunoglobulins response among COVID-19 patients, COVID-19 vaccine recipients and random individuals. METHODS: A total of 665 participants including 233 COVID-19 patients, 288 COVID-19 vaccine recipients, and 144 random individuals were investigated for anti-COVID-19 immunoglobulins (IgA, IgG, IgM). RESULTS: Among COVID-19 patients, 22.7% had detectable IgA antibodies with a mean of 27.3±57.1 ng/ml, 29.6% had IgM antibodies with a mean of 188.4±666.0 BAU/ml, while 59.2% had IgG antibodies with a mean of 101.7±139.7 BAU/ml. Pfizer-BioNTech vaccine recipients had positive IgG in 99.3% with a mean of 515.5±1143.5 BAU/ml while 85.7% of Sinopharm vaccine recipients had positive IgG with a mean of 170.0±230.0 BAU/ml. Regarding random individuals, 54.9% had positive IgG with a mean of 164.3±214 BAU/ml. The peak IgM response in COVID-19 patients was detected early at 15-22 days, followed by IgG peak at 16-30 days, and IgA peak at 0-60 days. IgM antibodies disappeared at 61-90 days, while IgG and IgA antibodies decreased slowly after the peak and remained detectable up to 300 days. The frequency of IgG positivity among patients was significantly affected by increased age, admission department (inpatient or outpatient), symptoms, need for oxygen therapy, and increased duration between positive COVID-19 RT PCR test and serum sampling (p˂0.05). Positive correlations were noted between different types of immunoglobulins (IgG, IgM, and IgA) among patients. CONCLUSIONS: Natural infection and COIVD-19 vaccines provide IgG-mediated immunity. The class, positivity, mean, efficacy, and duration of immunoglobulins response are affected by the mechanism of immunity and host related variables. Random community individuals had detectable COVID-19 IgG at ~55%, far from reaching herd immunity levels.

Transoral Endoscopic Resection of Oropharyngeal Pedunculated Giant Fibrolipoma Using Harmonic Scalpel: A Case Report.

Lipoma is the most common soft tissue benign tumor in the body. It can occur in the head and neck area as well. Fibrolipoma is a variant of lipoma that contains fibrous tissue. Fibrolipomas of the head and neck are relatively rare, and their presentation depends largely on their size and location; some slowly growing tumors might go unnoticed until they reach significant size and become symptomatic. Here, we report a case of 64-year-old male who presented with large pedunculated oropharyngeal fibrolipoma that originated from the posterior oropharyngeal wall and extended downward into the postcricoid area and cervical esophagus. It was excised transorally using rigid endoscope, and ACE Harmonic scalpel was utilized to excise this 16.7 cm long mass. The postoperative pain was minimal, the surgical site showed complete healing, and oral diet was resumed easily in 5 days.

Pfizer-BioNTech and Sinopharm: A Comparative Study on Post-Vaccination Antibody Titers.

COVID-19 (coronavirus disease 2019) vaccines induce immunity through different mechanisms. The aim of this study is to compare the titers of specific antibodies in subjects vaccinated with either the Pfizer-BioNTech COVID-19 vaccine or the Sinopharm vaccine. This prospective observational cohort included Jordanian adults vaccinated with two doses, 21 days apart, of either of the two aforementioned vaccines. Titers were collected 6 weeks after the administration of the second dose. Overall, 288 participants were included, of which 141 were administered the Pfizer-BioNTech vaccine, while 147 were administered the Sinopharm vaccine. Remarkably, 140 (99.3%) of the Pfizer-BioNTech vaccine recipients had positive IgG titers, while 126 (85.7%) of Sinopharm recipients had positive IgG (p < 0.001). The mean titer for IgG among Pfizer-BioNTech recipients was 515.5 ± 1143.5 BAU/mL, compared to 170.0 ± 230.0 BAU/mL among Sinopharm subjects (p < 0.001). Multivariable regression analysis showed that the Pfizer-BioNTech vaccine positively correlated with positive IgG titers (OR: 25.25; 95% CI: 3.25-196.15; p = 0.002), compared with a negative effect of cardiovascular diseases (OR: 0.33; 95% CI: 0.11-0.99; p = 0.48) on IgG titers. In conclusion, fully vaccinated recipients of the Pfizer-BioNTech vaccine had superior quantitative efficiency compared to Sinopharm recipients. A booster dose is supported for Sinopharm recipients, or those with chronic immunosuppressive diseases.

A prediction model of risk factors for complications among SARS-CoV2 positive patients: Cases from Jordan.

BACKGROUND: The number of COVID-19 infected patients has been soaring in the Middle East countries. The disease poses a significant threat, decisions about prioritizing care should be made in accordance with the proven risk factors for complications. OBJECTIVE: The present study provides the first bespoke prediction model in the Middle East to identify COVID-19 patients, who are at higher risk for complications. METHOD: A case-control study design was adopted to compare the characteristics of successfully recovered patients with those who had complications. Complications were defined as admission to the intensive care unit, mechanical ventilation, sepsis or septic shock, pneumonia or respiratory failure, and death. The prediction model was created through multivariable logistic regression. Overall statistical significance tests for the model were carried out. RESULTS: All COVID-19 infected hospitalized patients (n = 133) in Amman - Jordan were included in the study. Successfully recovered were 125 patients. The median age (IRQ) was 26 (10-40). Almost 30% were >40 years. Patients with complications were eight patients, age 63 (51.5-71.5). The prediction model identified the following variables as risk factors: diabetes (OR = 59.7; 95% CI: 3.5-1011.5, p = 0.005), fever (OR = 24.8; 95% CI: 1.4-447.3, p = 0.029), SHORTNESS OF BREATH (OR = 15.9; 95% CI: 1.3-189.7, p = 0.029), body mass index (OR = 0.74; 95% CI: 0.61-0.88, p = 0.001), abnormal Neutrophils (OR = 16.8; 95% CI: 1.0-292.0, p = 0.053). Prediction model was statistically significant, χ2(5) = 86.1, p < 0.0005. CONCLUSIONS: Unlike reports from China, the most influential variables that led to disease progression in Jordanian patients were diabetes, fever, shortness of breath, body mass index, and abnormal neutrophils. Similar to reports from the USA, smoking was not a leading factor for complications. Comorbidities and patient health status, rather than age, were the primary risk factors for complications. Treatment with Hydroxychloroquine showed no protective effect.

Clinical, sinonasal, and long-term smell and taste outcomes in mildly symptomatic COVID-19 patients.

INTRODUCTION: Coronavirus 2019 disease (COVID-19) has variable clinical, sinonasal, and smell/taste outcomes. METHODS: Observational study was conducted at a tertiary hospital in Amman, Jordan. Demographic data, clinical presentation and smoking status were collected. Sinonasal symptoms, using Sino-Nasal Outcome Test (SNOT-22) Questionnaire, were evaluated. Smell/taste dysfunction was followed for three months. RESULTS: Ninety-Seven patients had satisfactory responses. Eighty-six patients were symptomatic (41 at presentation, and 45 during admission). Among those patients, 59.3% had cough, 52.3% sore throat and 48.8% fever. The most common initial symptom was sore throat. Shortness of breath and smell/taste dysfunction were significantly higher in females. Surprisingly, shortness of breath was more common in non-smokers. Smell/taste dysfunction affected 25.6% of patients, but was the first symptom in only one patient. Fourteen of 22 symptoms in SNOT-22 had significant increase. The overall average of symptoms scores increased from 0.472 to 1.034, with smell/taste dysfunction to have the most increment. The latter symptom recovered completely in 81% and dysgeusia developed in 9.5% at three months, and it recovered completely in all patients at six months. CONCLUSION: Although COVID-19 may produce severe lower airways disease, it has modest effect on nose and paranasal sinuses. Moreover, smell/taste dysfunction is a prominent symptom, but it usually recovers dramatically.

Congenital Hairy Polyp Causing Severe Upper Airway Obstruction in a Newborn: A Case Report.

BACKGROUND Hairy polyps are rare tumors mainly comprising fatty tissues covered by skin and hair follicles, with varied localizations and sizes. Early excision of the polyps by surgery is an effective treatment resulting in a permanent cure. We present a case of successful management of severe obstruction of the oropharynx in a newborn who presented with a large mass of congenital hairy polyp. CASE REPORT A vaginally delivered infant, weighing 3 kg, presented immediately after birth with cyanosis symptoms, failure of the first cry, and respiratory distress signs. The newborn was born to a mother with an uneventful pregnancy. Screening tests during the pregnancy reported no congenital anomalies. The newborn's hematological and biochemical test results were normal. After presenting these symptoms, the newborn was immediately intubated and put on a nasogastric feeding tube, which revealed a small portion of a polyp-like mass. A computed tomography (CT) scan further confirmed a large pedunculated mass, measuring 3×2 cm, arising from the soft palate, and obstructing the oropharynx. Histopathological examination confirmed the presence of a hairy polyp. The polyp was wholly removed transorally using the Covidien LigaSure device without the need for endoscopy. This procedure allowed safe extubation, and the baby was discharged home without symptoms 4 days after birth. CONCLUSIONS This case sheds light on the importance of considering hairy polyp in the differential diagnosis of pharyngeal mass with respiratory distress in pediatric patients. This report also describes our experience using the LigaSure surgical device without needing endoscopic visualization to successfully resect the hairy polyp without complications.

Comparison between transtympanic and elevation of tympanomeatal flap approaches in tympanoplasty.

OBJECTIVE: Transtympanic tympanoplasty is an easy way of introducing a graft through the tympanic membrane to repair a perforation. The aim of our study is to compare the transtympanic technique with the usual method of elevating a tympanomeatal flap. STUDY DESIGN: Prospective randomized trial. SETTING: Tertiary referral teaching hospital. PATIENTS: Patients undergoing surgery for tympanic membrane perforations by the ENT team of King Abdullah University hospital between April 2004 and June 2009. INTERVENTIONS: Surgery. MAIN OUTCOME MEASURES: Perforations were stratified according to their sizes. Hearing was assessed preoperatively and postoperatively. The success rates defined as perforation closure and hearing improvement were compared between the 2 groups. RESULTS: A total number of 61 patients were enrolled in this study; 29 patients underwent the transtympanic approach, and 32 patients had a tympanomeatal flap elevated under general anesthesia. There was no statistical difference in the success rate between the 2 groups for all perforation sizes, although the tympanomeatal flap elevation technique was more effective in large perforations. There was a statistically significant average of 9 minutes saved in the transtympanic approach. There was a significant advantage in hearing improvement at 1 kHz favoring the transtympanic method. CONCLUSION: Transtympanic tympanoplasty is a simple technique with comparable success rate to the tympanomeatal flap technique in tympanic membrane closure and hearing results. We recommend it for small- and medium-sized perforations.
