ABSTRACT
BACKGROUND: Brucellosis is among the most common zoonotic bacterial infections, leading to major public health consequences in endemic areas such as Saudi Arabia. Primary healthcare is crucial in controlling brucellosis, as it serves as the frontline for disease prevention, early detection, and appropriate management. However, enhancing the contribution of primary healthcare to the entire brucellosis notification process is necessary to minimize the underreporting and inadequate data collection, which hinders the implementation of effective control measures. OBJECTIVE: The objective of the study is to assess primary care physicians' knowledge and practice of clinical preventive management in Saudi Arabia regarding brucellosis using an adapted assessment tool featuring a semi-structured questionnaire. SUBJECTS AND METHODS: The current study's design is a cross-sectional study based on a questionnaire. Three hundred and seventy-three primary healthcare physicians in Saudi Arabia were chosen for self-administered online standardized questionnaires. RESULTS: One-third of the participants answered all the knowledge assessment questions correctly. Most participants had more than 10 years of professional experience and were 40 or older. In response to the practice assessment questions, 210 physicians stated that they had encountered at least one case of brucellosis, and two-thirds had no compliance with the notification process of their cases. CONCLUSION: The limited knowledge and improper practice of primary care physicians regarding human brucellosis are possible underlying reasons for the underdiagnosis and underreporting of brucellosis patients at primary health care clinics in Saudi Arabia. Most research indicates that implementing specific educational programs to improve knowledge is necessary for primary healthcare workers. Furthermore, enhancing the community interaction between healthcare centers and the community facilitates effective control measures against brucellosis.
ABSTRACT
BACKGROUND: There are limited data from Saudi Arabia on the prevalence and characteristics of maxillary sinus septa. OBJECTIVE: Determine the prevalence and morphological characteristics of septa in the maxillary sinus and their relationship to gender and age using cone beam computed tomography (CBCT). DESIGN: Cross-sectional SETTING: CBCT images acquired from the maxillofacial radiology department in a dental school. PATIENT AND METHODS: CBCT scans of 1010 maxillary sinuses from 505 patients were analyzed to determine the prevalence, location, type, and orientation of maxillary sinus septa. Descriptive statistics, chi-square tests and t tests were used to analyze the data. MAIN OUTCOME MEASURES: The prevalence, location, type, and orientation of maxillary sinus septa. SAMPLE SIZE: 1010 sinuses from 505 patients. RESULT: Approximately 46% of the studied patients had maxillary septa, which were present in 370 (37%) sinuses. About 64% of the septa were present on the right side and 85.7% of all septa were mediolater-ally oriented. The mean height of the septa was 6.06 mm (0.84) in the right sinuses and 5.70 mm (0.93) in the left sinuses. Multiple septa were found in 101 patients (20%). Among males, 58.5% had septa compared to 34% of females (P<.001.) A significant positive association was found between age and the presence and number of septa, P<.001. CONCLUSIONS: Maxillary sinus septa were highly prevalent with various heights and directions among the studied sample. Careful assessment of different anatomic variation must be conducted prior to any maxillary sinus augmentation, particularly in older patients. LIMITATIONS: Cross-sectional evaluation of CBCT images from one dental school patient population; thus, the findings cannot be generalized to other populations. CONFLICT OF INTEREST: None.
