RESUMO
INTRODUCTION AND IMPORTANCE: Pilomatrixoma is a superficial benign skin tumor that originates from the matrix cells of the hair follicles. It presents more frequently during the first two decades of life and usually involves the head and neck, most often in the eyelid or eyebrow area. CASE PRESENTATION: We present a case of pilomatrixoma, which appeared at the age of 14 years with history of recurrent inflammation and discharge mimicking a ruptured epidermal cyst. DISCUSSION: Pilomatrixomas are often confused clinically with other benign masses, encountered in the clinical practice more frequently like dermoid cysts and epidermal inclusion cysts. The rate of accurate preoperative diagnosis ranges between 0%-30% and the correct diagnosis can be established only after excision and histopathological examination. Our case demonstrates an atypical presentation of pilomatrixoma as an epidermal inclusion cyst. CONCLUSION: Ophthalmologists and ocular pathologists should be aware of the atypical presentation of pilomatrixomas to ensure early accurate diagnosis and curative treatment.
RESUMO
BACKGROUND: The usability of a digital library depends on a myriad of factors ranging from the end users' ability to website complexity. Although digital libraries provide instant access to online content, offering an efficient reference platform, their usability is highly variable. OBJECTIVE: The aim of this study was to measure users' perspectives and usability of the digital library of the Saudi Commission for Health Specialties (SCFHS). METHODS: A web-based questionnaire survey was conducted using a validated System Usability Scale (SUS) containing 5 positive and 5 negative items on the usability of the digital library. The SUS standard cut-off score of 68 was considered for interpretation. RESULTS: The overall mean SUS score of digital library usability was 52.9 (SD 15.2) with a grade "D" categorization, indicating low usability. The perceived measures of attributes of the 10 SUS items of findability, complexity, consistency, and confidence obtained below average scores. Only item 1 relating to perceived willingness to use the digital library frequently obtained a score above the targeted benchmark score (mean score 3.6). Higher SUS scores were associated with training (P=.02). Men felt the digital library to be more complex (P=.04) and board-certified physicians perceived a greater need for training on digital library use (P=.05). Only the UpToDate database was widely used (72/90, 80%). CONCLUSIONS: These findings demonstrate the low usability of the extensive facilities offered by the SCFHS digital library. It is pivotal to improve awareness of the availability of the digital library and popularize the databases. There is also a need for improved user training to enhance the accessibility and usability of the multiple databases.
RESUMO
Objective To assess the quality of life (QoL) in Saudi children with cochlear implants (CI) and determine sociodemographic and clinical factors that have an impact on the perceived QoL. Methods A cross-sectional study is performed by comparing the QoL of Saudi toddlers and young CI recipients with normal children, using the Paediatric Quality of Life Inventory 4.0 - Generic core scale (PedsQLTM 4.0 - GCS). A self-administered questionnaire was sent to parents of paediatric patients, who had cochlear implantation at King Abdulaziz University Hospital (KAUH), from March 2016 to March 2018. Mothers of age-matched normal children who attended the obstetrics and gynaecology clinics at King Khalid University Hospital (KKUH), in November 2019 were considered as a control group. Results When children with CI and normal children PedsQLTM 4.0 - GCS subscales (physical, emotional, social, and school) and total functioning scores were compared, no single significant difference was noted between the groups. The sociodemographic and clinical factors that have an impact on the perceived QoL were: gender, birth order, and distance from the CI center. Emotional, social, psychosocial, and total functioning were the main dimensions affected. Conclusion The QoL of Saudi children with CI is comparable to those of normal children. However, among children with CI, gender, birth order, and distance from the CI center were found to have different effects on the QoL dimensions.
