Synchronous Nasopharyngeal and Thyroid Malignancies: A Case Report.

This report presents a case of primary non-keratinizing, undifferentiated nasopharyngeal cancer and an oncocytic (Hurthle cell) thyroid carcinoma developing simultaneously. The patient was diagnosed in August 2022 with nasopharyngeal carcinoma. After the staging process and before starting treatment for the patient, he was diagnosed with oncocytic (Hurthle cell) thyroid carcinoma on October 2022. Synchronous primary head and neck malignancies are well-known in the medical field. However, this is a rare case of two primary tumors of mucosal and non-mucosal carcinomas, highlighting the importance of discussing head and neck malignant cases in the multidisciplinary team meeting and performing frequent imaging and endoscopic examination for suspicious cases, especially in elderly patients. This case report describes the cases, the management modalities, and the outcomes, informing clinicians of the importance of considering the possibility of multiple primary malignancies when evaluating patients with head and neck tumors and a better approach to this rare and challenging case to ensure successful management.

The Relationship Between Noise-Induced Hearing Loss Awareness and the Use of Personal Listening Devices in Makkah Region, Saudi Arabia.

Introduction Noise-induced hearing loss (NIHL) is one of the most common avoidable reasons for hearing impairment worldwide. Work-related, genetic, infectious, and environmental factors all have a part in defining the level of hearing impairment. Nevertheless, the use of personal listening devices (PLDs) is popular nowadays, particularly among younger people. Healthy behaviors are needed to prevent them from developing hearing loss. Our objective is to evaluate the knowledge level of NIHL among the people of Makkah, Saudi Arabia, and understand its association with PLDs. Methods A cross-sectional survey was performed in December 2022 by sending an online survey on various social media applications. An electronic Arabic questionnaire with a total of 37 questions was designed to explore the participants' demographic data, history of hearing loss, risk factors, attitudes, and awareness of NIHL. Results Almost 22% of the study had mild-to-severe hearing impairment. Hearing issues were especially common among male individuals. A higher incidence of hearing impairments was seen in individuals who were utilizing a sound degree of more than 80%. The causes for NIHL comprised exposure to occupational noise, duration of the listening session per day, and the level to which the sound of the television or the broadcasting was raised. Approximately 77% of the participants preferred to reduce the sound of their personal audio devices (PADs) to prevent NIHL. Conclusion According to this study, there is a high prevalence of hearing problems in the Saudi population. Most of the respondents understood the risk factors linked to NIHL. There is a need for more NIHL awareness campaigns to educate the Saudi population and reinforce positive, healthy listening habits.

Primary Schwannoma of the Thyroid Gland in a 71-Year-Old Woman: A Case Report.

Schwann cells in the body's nerve sheath can develop into benign tumors known as schwannomas. While thyroid gland schwannomas are uncommon and are rarely documented in the literature, they are less unusual than those appearing in the head and neck region. The rare nature of schwannomas connected to the thyroid gland adds to the difficulty in detecting them prior to surgery. At present, the most popular form of treatment for thyroid schwannomas is surgical resection, which is considered to be curative. A mass excision or lobectomy has a favorable prognosis, few postoperative complications, and a low risk of tumor recurrence. This paper reports the case of a 71-year-old woman who presented with left neck swelling that had been increasing in size over a number of years. An ultrasonography examination revealed multiple bilateral thyroid nodules with high vascularity. The patient's right thyroid lobe exhibited benign nodular hyperplasia while the thyroid tissue of the isthmus exhibited benign nodular hyperplasia and schwannoma. Following the diagnosis, the patient's mass was successfully surgically removed.

Efficacy of prophylactic pre-operative desmopressin administration during functional endoscopic sinus surgery for chronic rhinosinusitis: A systematic review and meta-analysis of randomised placebo-controlled trials.

OBJECTIVES: To examine the efficacy of prophylactic desmopressin versus placebo among patients undergoing functional endoscopic sinus surgery (FESS). DESIGN: Systematic review and meta-analysis of randomised controlled trials (RCTs). SETTING: The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Scopus, and Web of Science databases were screened from inception until 18 March 2022. PARTICIPANTS: Patients undergoing FESS. MAIN OUTCOME MEASURES: Primary efficacy endpoints comprised intraoperative blood loss, visual clarity, and operation time. Secondary endpoints comprised side effects. The efficacy endpoints were summarised as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). RESULTS: Five RCTs comprising 380 patients (desmopressin = 191 patients and placebo = 189 patients) were included. Collectively, the included RCTs had an overall low risk of bias. The pooled results showed that the mean intraoperative blood loss (n = 5 RCTs, MD = -37.97 ml, 95% CI [-56.97, -18.96], p < .001), 5-point Boezaart scores (n = 2 RCTs, MD = -.97, 95% CI [-1.21, -.74], p < .001), and 10-point Boezaart scores (n = 2 RCTs, MD = -3.00, 95% CI [-3.61, -2.40], p < .001) were significantly reduced in favour of the desmopressin group compared with the placebo group. Operation time did not significantly differ between both groups (n = 5 RCTs, MD = -3.73 min, 95% CI [-14.65, 7.18], p = .50). No patient in both groups developed symptomatic hyponatremia (n = 3 RCTs, 194 patients) or thromboembolic events (n = 2 RCTs, 150 patients). CONCLUSIONS: Among patients undergoing FESS, prophylactic administration of desmopressin does not correlate with significant clinical benefits. Data on safety is limited. Future research may explore the synergistic antihaemorrhagic efficacy and safety of tranexamic acid (TXA) plus desmopressin versus TXA alone among patients undergoing FESS.

Assessment of the Prevalence of the Use of Nasal Decongestants Among the General Population in Saudi Arabia.

Background A topical nasal decongestant (NDC) is widely prescribed in ENT practice and used as self-medication because it is available over the counter, which makes it an easily accessible medication. Due to its common and long-term use, it is associated with serious nasal complications. It is commonly self-administrated in many otolaryngology diseases like the common cold, sinusitis, and acute or chronic rhinitis. The long-term usage of nasal decongestants is associated with significantly increased side effects. Aim To assess the prevalence of the usage of nasal decongestants among the general population in Saudi Arabia ad the pattern of its use. Methodology A questionnaire-based, cross-sectional survey was applied to level all available populations in Saudi Arabia. Participants with ages aged 10 to 60 years old in Saudi Arabia were invited to participate in the survey. Data were collected from participants using a predesigned online questionnaire. The questionnaire included the participant's demographic data, NDC use, and pattern of use. The questionnaire was uploaded online by researchers and their friends using social media platforms. Results A total of 1456 participants completed the study questionnaire. Participants ages ranged from 10 to 60 years with a mean age of 26.9 ± 12.4 years old. Exact 585 (40.2%) participants were males and 1270 (87.2%) were from urban regions. A total of 657 (45.1%) respondents reported using nasal decongestants while 799 (54.9%) did not use NDC. As for the duration of use, 70.8% used NDC for less than five days and 13.5% used it for 5-15 days. The most reported causes of using NDC were nasal obstruction (62.7%) and common cold (25.7%). Conclusions In conclusion, the study revealed that the frequency of using nasal decongestants was common (45.1%) in the study. More efforts should be paid to improve public awareness regarding indications, duration of use, and method of using nasal decongestants to avoid rebound reactions that may affect patients' daily life activities.

Larazotide acetate for treatment of celiac disease: A systematic review and meta-analysis of randomized controlled trials.

PURPOSE: The standard of care for treatment of celiac disease (CD) is a stringent lifetime gluten-free diet (GFD). Larazotide acetate (AT-1001) is an anti-zonulin which functions as a gut permeability regulator for treatment of CD. We endeavored to conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) which studied the efficacy and safety of AT-1001 in patients with CD. METHODS: We examined four databases from inception to 20-August-2020. We pooled continuous outcomes as mean difference and dichotomous outcomes as risk ratio with 95% confidence interval under the fixed-effects meta-analysis model. RESULTS: Four RCTs met our eligibility criteria, comprising 626 patients (AT-1001, n=465, placebo, n=161). Three and two RCTs reported outcomes of patients undergoing gluten challenge (intake of 2.4-2.7 grams of gluten/day) and GFD, respectively. For change in lactulose-to-mannitol ratio, the endpoint did not significantly differ between AT-1001 and placebo groups, irrespective of the gluten status. Subgroup analysis of patients undergoing gluten challenge showed AT-1001 treatment (compared with placebo) significantly correlated with better symptomatic improvement in the two endpoints of change in total gastrointestinal symptom rating scale (total GSRS) and CD-specific GSRS (CD-GSRS). However, no significant difference was noted among patients undergoing GFD for the abovementioned two efficacy endpoints. Compared with placebo, AT-1001 favorably reduced the adverse event (AE) of gluten-related diarrhea in patients who underwent gluten challenge. Other AEs were comparable between both AT-1001 and placebo groups. CONCLUSIONS: AT-1001 is largely well-endured and seems somehow superior to placebo in alleviating gastrointestinal symptoms among CD patients undergoing gluten challenge. Nevertheless, additional RCTs are warranted to validate these findings.

A systematic review and dose-response meta-analysis on the efficacy of dapagliflozin in patients with type 1 diabetes mellitus.

Formulation of insulin analogs and its delivery are developed in over recent years but glycemic control in most patients with type-1 diabetes mellitus (DM) is not adequate yet. The aim of this meta-analysis is to evaluate the efficacy of dapagliflozin in patients with type-1 DM. The MEDLINE/PubMed, Scopus, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science databases were searched up to Aug 2020 to identify the potential literature. Random-effects model (DerSimonian and Laird method) was used to estimate the pooled effect size as weighted mean difference (WMD) with 95 % confidence interval (CI). Five randomized placebo-controlled trials with 11 arms were included in the quantitative analysis. The pooled results suggested a significant reduction in glycated hemoglobin A1C (HbA1C; WMD: -0.36 %, 95 % CI: -0.55, -0.18), body weight (WMD: -4.02 kg, 95 % CI: -4.78, -3.25), and total daily insulin dose (TDID; WMD: -10.36 %, 95 % CI: -13.42, -7.29), as well as an increase in 24-h urinary glucose excretion (24-h UGE; WMD: 90.02 g/24-h, 95 % CI: 72.96, 107.09) in dapagliflozin group compared to control group. Dose of dapagliflozin had a significant effect on body weight reduction (Coef = -3.7, p = 0.01) and 24-h UGE (coef = 0.85, p = 0.005). Pooled results of this meta-analysis identified a significant reduction in HbA1c levels, body weight, and TDID, and a substantial increase in 24-h UGE in patients who received dapagliflozin versus placebo.
