Salvageable Intra-stent Coil Embolization Treatment for Spinal Dural Arteriovenous Fistula in a Child.

Spinal dural arteriovenous fistulae (SDAVF) are rare diseases that exhibit abnormal connections between arteries and veins. They are even rarer in the pediatric population and pose diagnostic and treatment challenges for physicians. Its presentation varies depending on the site and size of the SDAVF. Multiple management options are available, which are usually tailored depending on the patient's condition. Here, we present a rare case of SDAF in a four-year-old girl who initially presented with bilateral lower limb weakness. The patient was then treated successfully using primary major fistula point stenting and intra-stent coiling, with complete closure achieved. Full recovery was achieved over the course of follow-ups. The deep analysis of SDAVF, its classification, and the utilization of the best available endovascular tools by a dedicated neurovascular team offer the best outcome in dealing with complex spinal neurovascular pathologies.

Enhanced fluid drainage using a novel multi-pod drainage catheter: An in vitro evaluation.

BACKGROUND: A multi-pod catheter (MPC) is a large drainage catheter that can house multiple smaller retractable (MPC-R) and deployable catheters (MPC-D) within the body. OBJECTIVE: The drainage capabilities and resistance to clogging of a novel MPC have been assessed. METHODS: The drainage capabilities are evaluated by placing the MPC in a bag of either a non-clogging (H2O) or clogging medium. The results are then compared to matched-size single-lumen catheters with either a close (CTC) or open tip (OTC). The means of five test runs were used to measure drainage rate, maximum drained volume (MaxDV), and time to drain the first 200 mL (TTD200). RESULTS: In the non-clogging medium, MPC-D had a slightly higher MaxDV than MPC-R, and higher flow rate than CTC and MPC-R. Moreover, MPC-D needed less TTD200 than MPC-R. In the clogging medium, MPC-D had a higher MaxDV than CTC and OTC, higher flow rate, and faster TTD200 than CTC. However, comparison with MPC-R showed no significant difference. CONCLUSION: The novel catheter may offer superior drainage compared to the single-lumen catheter in a clogging medium, implying various clinical applications, particularly when clogging is a potential risk. Further testing may be required to simulate various clinical scenarios.

Woodhouse-Sakati Syndrome Presenting With Psychotic Features After Starting Trihexyphenidyl: A Case Report.

Woodhouse-Sakati syndrome is a rare, autosomal recessive, multisystemic disorder first identified as a constellation of hypogonadism, mental retardation, diabetes, alopecia, deafness, and electrocardiogram abnormalities.  We report a case of a 33-year-old woman who was born to consanguineous parents. She is suffering from hypergonadotropic hypogonadism, extrapyramidal symptoms, hypothyroidism, alopecia, and sensorineural hearing loss. Her MRI showed iron depositions in globus pallidus bilaterally. She underwent genetic testing and was diagnosed with Woodhouse-Sakati syndrome. She was started on trihexyphenidyl to treat her extrapyramidal symptoms. A few months later, she started to have psychotic symptoms in the form of auditory hallucinations and delusions of persecution.  Although she exhibited psychotic symptoms after starting trihexyphenidyl, it is less likely to be causing her symptoms since the symptoms started a few months after taking the medication and she was not on high doses. Thus, it is more likely to be a part of Woodhouse-Sakati syndrome.

Otolaryngologists, Pediatricians, and Emergency and Family Medicine Physicians Adherence to Acute Otitis Media Diagnosis and Management Guidelines: A Retrospective Study in a Saudi Arabian Tertiary Center.

Background Acute otitis media (AOM) is one of the most common conditions in the pediatric population and a common reason for physicians to prescribe antibiotics. Most children will develop otitis media at least once during their life. Objectives Our study aimed to evaluate and compare the adherence of family medicine physicians, otolaryngologists, pediatricians, and emergency medicine physicians to the American Academy of Pediatrics and American Academy of Family Physicians guidelines for the diagnosis and the management of AOM. Methods This is a retrospective study that was conducted at the Ministry of National Guard - Health Affairs affiliated hospitals and primary clinics in Riyadh, Saudi Arabia. All patients diagnosed with AOM and treated between 2016 and 2019 were included in the study. Exclusion criteria included any patient above the age of 18 years old or patients with incomplete data on their files. Variables included demographic data of the patients and treating physicians, associated infections, and whether the treating physician followed the diagnosis and management guidelines. Results Most patients were below the age of two years. Emergency medicine physicians were the most common to treat patients with AOM. Although most documentations were sufficient, 39.8% were insufficient or not written. Most (74%) physicians adhered to the diagnosis guidelines, while 57.5% adhered to management guidelines. Conclusion Although most physicians adhered to the diagnosis and treatment guidelines, stressing on the matter is essential to avoid unnecessary antibiotics use. We recommend further prospective studies with a bigger sample size of more than one center to have a more accurate reflection of the current situation.

Does shared decision making increase prostate screening uptake in countries with a low prevalence of prostate cancer?

BACKGROUND: Men over 50 should discuss the benefits and harms of prostate-specific antigen (PSA) testing with their doctors. OBJECTIVES: To investigate whether shared decision making (SDM) increases the uptake of prostate cancer screening practices among Saudi men. METHODS: This community-based study recruited men aged ≥ 50 years between January and April 2019. Sociodemographic characteristics, history, and current medical condition information were collected. SDM information with regards to prostate cancer screening was discussed. RESULTS: In total, 2034 Saudi men, aged between 50 and 88 years, agreed to participate in the current study. Prostate examination for early detection of cancer was recommended for 35.4% (720) of subjects. Of the subjects, 23.3% (473) reported that the physicians discussed the advantages and benefits of PSA testing, whereas only 5.6% (114) stated that the physicians explained the disadvantages and drawbacks of PSA testing. CONCLUSION: Our findings suggest that less than one fourth discussed the advantages and disadvantages of PSA testing with their physicians; of these, less than one third underwent PSA blood tests. Improvements are needed in SDM for and against PSA screening. SDM does not affect the intensity of PSA testing. Primary health care physicians should be actively involved in the SDM process.

Tobacco consumption and environmental exposure among healthcare students in King Saud University in Riyadh.

OBJECTIVES: The goal of this study was to determine the prevalence of tobacco smoking in healthcare students at a university in Riyadh, Saudi Arabia, along with environmental exposure and potential influential factors. METHODS: This observational cross-sectional study was conducted at King Saud University from January-April 2019. It included 1,273 randomly selected male and female first- to fifth-year undergraduate healthcare students from all health colleges at the university. The study used a self-administrated questionnaire and descriptive data analysis. Associations between variables were tested using a Chi-square test with the statistical significance set at P value < 0.05. RESULTS: Among the 1,273 respondents, the prevalence of tobacco product smoking was 13.7%. The prevalence was highest in the College of Applied Science (34.5%) and lowest in the College of Pharmacy (10.9%). Among those 18- to 21-year-olds, the prevalence was 43.1%, while it was 51.1% for the 22-25 age group and only 5.8% for those 26 or older. Common reasons for smoking cigarettes included having fun or passing time (45.2%) and relieving stress (33.3%). Among those who smoked a water-pipe (12.5%), the most common reason was to enjoy its flavors (42.1%). The prevalence of secondhand smoking at home was 31.7%, and environmental exposure was 42.5%. CONCLUSION: Tobacco consumption is a common problem among healthcare students including cigarette as well as the increasing consumption of water-pipe in addition to secondhand smoking. Along with proven strategies to promote smoking cessation, including smoke-free laws, improved access to effective quitting treatments and media campaigns are needed to reduce tobacco consumption.
