Objectives: In this study, we investigated the diagnostic value of fine needle aspiration cytology (FNAC) in salivary gland masses retrospectively. We compared FNAC and postoperative histopathologic results of patients who had undergone FNAC and had been operated on because of salivary gland masses.
Patients And Methods: Seventy six patients (40 females, 36 males; mean age 50.4 years; range 20 to 80 years) having salivary gland masses who underwent FNAC and surgical treatment between January 2001 and June 2008 were included in the study. Fine needle aspiration cytology and histopathologic results were compared retrospectively. The sensitivity, specificity, positive and negative predictive values and accuracy rate of the FNAC in salivary gland masses were evaluated in the light of the results.
Results: The most common benign and malign FNAC results were pleomorphic adenoma (22 patients; 29.7%) and mucoepidermoid carcinoma (4 patients; 5.4%), respectively. Fine needle aspiration cytology results of two patients were non-diagnostic and these patients were excluded. According to the FNAC and histopathologic results of 74 patients, sensitivity was found to be 80.9%, specificity 94.3%, positive predictive value 85% and negative predictive value 92.5% and accuracy rate of FNAC 90.5%.
Conclusion: Fine needle aspiration cytology is a reliable method that has high sensitivity to distinguish between benign and malign salivary gland lesions. In case of suspicious FNAC reports, reliability and diagnostic value of the method is decreased.

Introduction: Mumps is a vaccine-preventable disease caused by the paramyxovirus affecting the salivary gland and may be complicated by orchitis, oophoritis, and encephalitis. This study aims to describe the epidemiology, clinical presentation, and transmission of mumps cases in the Kingdom of Bahrain between 2012 and 2022.
Methodology: A retrospective cross-sectional study was conducted using national surveillance data of confirmed mumps cases, including all age groups and both Bahraini and non-Bahraini nationals, from January 2012 to December 2022.

Oral and maxillofacial diagnostic imaging is of paramount importance in dental clinical diagnosis, treatment planning, and follow-up procedures. Periapical radiographic examination and numerous panoramic systems are used in routine clinical dental practice. Cone beam CT is widely used and currently the method of choice in oral and maxillofacial implantology, endodontics, maxillofacial surgery, periodontics, degenerative temporomandibular joint disease, orthodontics, airway studies, sleep disorders, and forensic dentistry.

Background: I-MIBG scintigraphy plays a significant role in diagnosing Parkinson's disease (PD), with most studies primarily targeting cardiac uptake and relying on traditional ratio-based parameters for assessment. However, due to variations in scanning conditions and image processing methodologies, the clinical utility of different parameters remains a subject of debate. This study aims to evaluate the diagnostic accuracy of multi-parameter I-3-Iodobenzylguanidine (MIBG) scintigraphy and to identify the most reliable metrics for distinguishing PD from Parkinson-plus syndromes.

Objectives: The main symptom of diabetes mellitus (DM) is hyperglycaemia, and patients with DM often have microvascular complications, such as retinopathy, neuropathy, and nephropathy; macrovascular complications, such as coronary heart disease, peripheral arterial disease and cerebrovascular disease; and oral complications, such as xerostomia, hyposalivation and periodontal disease. The main aim of this study was to evaluate the submandibular and parotid glands in type 2 DM patients and healthy individuals and to determine the changes in the salivary glands caused by diabetes.
Materials And Methods: In this study, the salivary glands of 100 patients (50 individuals with type 2 DM and 50 healthy individuals) were evaluated by ultrasonography (US).
