BackgroundThyroid nodules are a common presentation in otolaryngology-head and neck clinics. The detection of thyroid nodules has increased significantly with the advancements in radiological technology such as computed tomography and ultrasound (US). The present study aims to improve the clinical practice and management of thyroid disorders by establishing correlations between US and cytological findings in the diagnosis of thyroid nodules. MethodologyA retrospective cohort study was conducted at the King Hamad University Hospital (KHUH), Bahrain. A total of 189 cases met the study criteria. Pathological records for thyroid nodule fine needle aspiration (FNA) cytology and US features of sampled nodules from the patients were obtained. The cytological results were categorized into the Bethesda grading system, while the US features were organized into internationally accepted features using the Thyroid Imaging Reporting and Data System (TIRADS). ResultsThe radiologic characteristics from US showed positive features largely for the composition (76.2%) and vascularity (59.3%). Very few showed echogenicity (6.9%). Most records indicated negatively for the shape (94.7%), margins (76.2%), echogenicity (63.5%), or echogenic foci (66.1%). Of the 47 cases in TIRADS 1 and 2, only two were found to be Bethesda 4 classification, showing that most of these nodules were benign. Among those with TIRADS 3 on US, 85% turned were benign (Bethesda 2), two of the remaining six were grade 3, and the other four were suspiciously malignant. Of the 100 cases in TIRADS 4 and 5, 63% were of Bethesda grade 2, and therefore, benign, 14% were mildly suspicious, and only 23% were in Bethesda grades 4-6. A significant positive correlation was noted between the TIRADS and Bethesda scores (r = 0.338, p ≤ 0.001). ConclusionsIf the thyroid nodules are classified properly by US using the TIRADS system, the probability of a nodule being malignant can be established with a certain level of confidence. The appropriate management of the nodule can be initiated avoiding unwarranted FNA procedures.

Introduction: Chronic rhinosinusitis (CRS) is an inflammatory condition affecting the sinonasal mucosa with duration of more than 12 weeks. Multifactorial aetiology contributes to its refractoriness. Functional endoscopic sinus surgery (FESS) is the most common surgical technique preferred in CRS not responding to medical management, showing high success rates. However, some failure has been noted, requiring revision FESS. CT (Computed Tomography) is a diagnostic tool for CRS, and aids in improving surgical outcomes. Combined with the Lund-Mackay scoring system, CT can help stage the CRS, predicting the need for revision surgery. Methods: In our paper, we aimed to study the relationship between severity of CRS using radiological staging and revision of functional endoscopic sinus surgery, assessing outcome after at least 1 year of follow-up. There was a single centre retrospective study involving 150 patients selected by random sampling, to study the correlation between the severity of chronic rhinosinusitis and revision of functional endoscopic sinus surgery (FESS). The study was conducted in the ENT department of King Hamad University Hospital, Bahrain for a time period of 6 months. Records were scanned and scored using Lund-Mackay system. Lund Mackay score of 10 and above was considered severe. The relation between increased severity with Lund Mackay score on the CT scan and the need for revision sinus surgeries was then determined. Results and Conclusion: This study concludes that LMS score in CT scans can be used to predict the outcomes of primary FESS procedure and the need for revision surgery in the management of CRS.

Objective: Diode-assisted laser turbinoplasty is a popular surgical technique that improves airflow during nasal obstruction. In this study, we aimed to evaluate the efficacy of a diode laser for turbinate hypertrophy by using rhinomanometry. Methods: This cross-sectional study included 199 patients for 13 months. Preoperative, intraoperative, and 6-week postoperative rhinomanometry values were measured. Results: The most common intraoperative symptoms were olfactory annoyance (barbecue smell) (76.4%) and a painful burning or stinging sensation (64.3%). The inspiratory and expiratory mean nasal airflow values increased both intraoperatively and postoperatively, illustrating the effect of decongestants and inferior turbinate surgery. Intraoperatively, inspiration improved by 262.73 ± 196.09 (p < 0.01) and expiration by 247.94 ± 180.05 (p < 0.01). Postoperative inspiration improved by 254.03 ± 199.08 (p < 0.01) and expiration by 244.05 ± 194.57 (p < 0.01). Postoperative snoring (22.6%, p = 0.026) and nasal obstruction (20.2%, p = 0.042) were significantly higher in female than in male patients. Conclusions: The therapeutic efficacy of using diode lasers in inferior turbinate resection was established in this study on the basis of rhinomanometric data with a follow-up of 6 weeks. Postoperative nasal obstruction was effectively decreased and the other symptoms displayed a female preponderance.
