Comparative Efficacy of Non-Invasive Therapies in Temporomandibular Joint Dysfunction: A Systematic Review.

Temporomandibular disorder (TMD) is a multifaceted disorder impacting the temporomandibular joint (TMJ), causing substantial discomfort and functional limitations. This systematic review aims to comprehensively assess the effectiveness of non-invasive treatment modalities for TMJ dysfunction, prioritizing a definitive protocol to ensure patient safety and enhance quality of life. Employing the PRISMA guidelines, we meticulously analyzed 20 studies from a pool of 1,417 articles sourced from databases such as PubMed, Google Scholar, ScienceDirect, and Medline. These studies underscore the multifarious nature of TMD and the varied responses to treatments such as physical therapy, laser therapy, ultrasound and electrical stimulation, splint therapy, injections, and arthrocentesis. Notably, the review highlights the paramount importance of precise diagnosis, often through surface electromyography, followed by a tailored treatment approach integrating manual therapy, counseling, and splint therapy. The systematic analysis revealed that while certain treatments such as transcutaneous electrical nerve stimulation and low-level laser therapy showed limited efficacy, combination therapies, especially those involving manual therapy, counseling, and splint therapy, demonstrated substantial improvement in reducing pain, depression, and anxiety. The findings advocate for a non-invasive, patient-centric approach, emphasizing education and symptom management before considering more invasive procedures such as injections and arthrocentesis. The review identifies the need for more comprehensive, longitudinal studies to establish a standardized, evidence-based treatment protocol for TMJ dysfunction, aiming to improve patient outcomes holistically.

Symptomatic arteriovenous malformation of the thyroid/parathyroid gland: A case report.

Arteriovenous malformations (AVMs) are complex vascular lesions most commonly found in the brain and infrequently found in the head and neck. AVMs are characterized by a tangle of blood vessels called a nidus, which shunts blood from an artery directly to a draining vein. Various treatments are available, including surgical resection and endovascular embolization. Here, we report the case of a 32-year-old male patient who complained of painful pulsating left neck swelling with dysphagia for 1 year, which turned out to be an AVM alongside the left thyroid gland. The AVM was treated by embolization using Onyx in 2 sessions. The patient has been free of symptoms since the treatment.

Research anomalies in criminology: How serious? How extensive over time? And who was responsible?

A variety of ways to detect questionable research practices in small sample social science surveys have been discussed by a variety of authors. However, some of those approaches (e.g., GRIM test, SPRITE test) do not work well for results obtained from larger samples. Here several approaches for detecting anomalies in larger samples are presented and illustrated by an analysis of 78 journal articles in the area of criminology, 59 by Dr. Eric Stewart, published since 1998 with similar methods and/or authors. Of all 59 articles, 28 (47.5%, p < .001, d = 0.94) had two or more major anomalies compared to none of the 19 control group articles. It was also found that the larger the role of Dr. Stewart in article authorship, the greater the number of anomalies detected (p < .001, d = 1.01) while for his coauthors, there were few significant relationships between their roles and total anomalies. Our results demonstrate that extensive problematic results can remain undetected for decades despite several levels of peer review and other scientific controls; however, use of two types of control groups and the use of statistical methods for measuring and evaluating anomalies can improve detection.

Initial experience with Scepter Mini dual lumen balloon for embolization of cerebrovascular diseases.

OBJECTIVE: Endovascular treatment of cerebrovascular diseases is often challenging due to small caliber, tortuous distal vessels. Several devices and techniques have evolved to overcome these challenges. Recently, a low profile dual lumen microballoon catheter, specifically designed for distal navigation is employed for neurovascular procedures. Due to its recent advent, scarce data is available on clinical utility and safety of Scepter Mini. The aim of this case series is to report our initial experience with Scepter Mini in the management of various cerebrovascular diseases. METHODS: All interventional neurovascular cases performed using Scepter Mini between January 2020 till April 2021 were included. Data regarding patient demographics, procedural details and complications was retrospectively collected from patient's electronic medical record and procedure reports. RESULTS: Total twelve embolization procedures were performed in eleven patients, including six brain arteriovenous malformation, two dural arteriovenous fistula, one vein of Galen malformation and three hyper-vascular glomus tumor embolizations. All procedures were successfully performed with adequate penetration of the embolic agent. Complete embolization was performed in six procedures, while intended partial embolization was performed in the rest of procedures. Scepter Mini was solely used in ten procedures, however in the other two embolization procedures it was used as an additional conjunct tool to complete the intended embolization. No balloon related complication was observed in any procedure. CONCLUSIONS: Scepter Mini dual lumen microballoon catheter is safe and feasible for delivery of liquid embolic agents for cerebrovascular embolization procedures.

Ulnar artery access for intracranial mechanical thrombectomy procedure: A salvage option after failed trans-femoral and trans-radial access.

84 years old gentle man with past medical history of hypertension and diabetes presented with sudden onset right sided weakness and aphasia for two hours. Initial neurological assessment revealed National Institute of Health Stroke Scale (NIHSS) 17. Computed tomography (CT) scan demonstrated minimal early ischemic changes along left insular cortex with occlusion of left middle cerebral artery (MCA). Based on clinical and imaging findings, decision was made to perform mechanical thrombectomy procedure. Initially, right common femoral artery approach was utilized. However, due to unfavorable type-III bovine arch, left internal carotid artery could not be engaged via this approach. Subsequently, access was switched to right radial artery. Angiogram revealed small caliber radial artery, with larger caliber ulnar artery. Attempt was made to advance the guide catheter through the radial artery, however significant vasospasm was encountered. Subsequently, ulnar artery was accessed and successful thrombolysis in cerebral infarction (TICI) III left MCA reperfusion was achieved with a single pass of mechanical thrombectomy via this approach. Post procedure neurological examination demonstrated significant clinical improvement. Doppler ultrasound 48 hours after the procedure demonstrated patent flow in radial and ulnar arteries with no evidence of dissection.

Unruptured Intradural Posterior Circulation Dissecting/Fusiform Aneurysms Natural History and Treatment Outcome.

BACKGROUND: The natural history and outcome of unruptured posterior circulation dissecting fusiform aneurysms is not fully understood. These have a high risk of morbidity and mortality, not only due to natural history but also due to the challenging and controversial treatment approaches currently available compared to other types of intracranial aneurysms. METHODS: We performed a retrospective study of a prospectively collected aneurysm database at a quaternary neurovascular hospital. We included consecutive patients with unruptured intradural vertebrobasilar dissecting aneurysms between January 2000 and July 2016 who were followed to 2020. Description of baseline, procedural, and outcomes data was performed. Comparisons of patient who had aneurysm rupture on follow-up, increase in 2 or more points of mRS in follow-up and progression of the aneurysm was performed. RESULTS: Seventy patients with 78 fusiform posterior circulation aneurysms were identified. Thirty-nine (55.7%) patients were male with a mean age of 51.7 years (SD ± 17.6). When multiple, aneurysms were more likely to be fusiform (60%) than saccular (40.0%). Baseline diameter (measured on CTA/MRA/DSA), length as well as symptomatic presentation were significantly higher in aneurysms which grew over time. Coronary disease, diabetes and growth were associated an >2 increase in mRS. Diabetes as well as initial symptomatic presentation were associated with rupture. CONCLUSIONS: Unruptured dissecting/fusiform aneurysm are associated with a considerable rate of rupture during follow-up. Growth is associated with morbidity even in the absence of rupture. Initial large size, coronary disease, diabetes, and to a lesser extent female gender may merit closer follow-up and/or prophylactic treatment.

Gender Differences in Smoking Attitude among Saudi Medical Students.

BACKGROUND: Smoking is a growing public health problem throughout the world. However, the attitude of males and females toward smoking may differ. Therefore, this study examines gender differences in smoking behavior and attitude among Saudi medical students. METHODS: From January 2020 to August 2020, a snowball cross-sectional online survey was conducted in five major regions of Saudi Arabia. Medical students (18 years or older) were invited to respond to the questionnaire. RESULTS: Out of the 421 respondents, 255 (60.6%) were female, 243 (57.7%) were between 18 and-24-year-old, and 164 (39%) were from the Eastern Province. The overall prevalence of smoking was 25.4% and was higher among males than females [(44% and 13.3%, respectively), P < 0.001]. However, there was no significant difference in the mean score of the overall attitude towards smoking between males and females [(3.02±0.44 and 3.00±0.34), respectively, P=0.64]. However, more female students believed e-cigarettes were harmful to health than male students [(4.19±1.04 and 4.45±0.9), respectively, P=0.002]. CONCLUSION: The study showed that male students smoke more than female students, and there were no significant differences in the overall attitudes score towards smoking. Therefore, campaigns are needed to decrease smoking rate, especially among male students.

Common ground, different path: Ulnar artery access for interventional neurovascular procedures.

BACKGROUND: Recently, radial artery access has gained popularity for interventional neurovascular procedures due to patient comfort and fewer complications. However, there are instances where the radial artery approach is not feasible. In such cases, trans-ulnar artery access (TUA) can offer an alternate route. There is limited data regarding neuro-interventional procedures performed via this approach. This study aims to evaluate the feasibility and safety of trans-ulnar approach for a wide range of interventional neurovascular procedures. MATERIALS AND METHODS: The data for all patients who underwent ulnar artery access for diagnostic or interventional neuroradiology procedures was retrospectively collected between September 2020 and March 2021. Patient demographics, procedural details, procedure success, and complications were recorded. RESULTS: During the study period, 23 patients underwent 24 trans-ulnar approach procedures. The mean age of patients was 50.1 ± 14.2 years. Fourteen diagnostic cerebral angiograms and ten interventional procedures were performed. All procedures were successfully completed via trans-ulnar approach without a switch to alternate access. No major access site complication was observed. CONCLUSION: Ulnar artery access is a safe and feasible option for neurovascular procedures. It can be effectively utilized for diagnostic cerebral angiography and a wide range of interventional procedures.

Exploring the path less traveled: Distal radial access for diagnostic and interventional neuroradiology procedures.

BACKGROUND: Recently there is a trend for radial first which advocates radial artery access as the first choice to perform diagnostic and interventional neurovascular procedures. Although safer than the conventional common femoral artery access, it is associated with a high rate of radial artery occlusion. Distal radial artery access is recently proposed to avoid this complication. This study aims to assess the feasibility and safety of distal radial artery access across a wide range of interventional neurovascular procedures. MATERIALS AND METHODS: All Interventional neurovascular cases attempted via distal radial artery access from September 2019 till March 2021 were included in the study. Data regarding patient demographics, distal radial artery diameter, access site cannulation, size of the sheath, procedural details including success rate and complications were collected. RESULTS: During the study period, 102 patients underwent 114 procedures via the distal radial artery approach. The mean age of patients was 41.9 ± 15.2 years. Overall procedure success rate via DRA was 94.7% (108/114). 72 diagnostic cerebral angiograms and 36 interventional procedures were successfully completed while six procedures required switching to alternate access. CONCLUSION: Distal radial artery access is a safe and feasible option for diagnostic cerebral angiography and a wide range of neurovascular procedures.

Salvage flow diverter stent across the posterior communicating artery for persistent retrograde filling of a giant internal carotid artery aneurysm after parent vessel occlusion.

Giant internal carotid artery (ICA) aneurysms are complex vascular lesions which are difficult to treat with open as well as endovascular surgery. Parent vessel occlusion is a well-established treatment option for such aneurysms. However, there have been a few reported cases of ruptured aneurysms related to the persistent retrograde filling after parent vessel occlusion. We report a case which highlights the usage of the flow diverter stent as a potential treatment strategy for the management of retrograde filling of aneurysms. A 54-year-old female was found to have a giant left ICA aneurysm on a brain magnetic resonance imaging during workup for headaches. She underwent occlusion of the left ICA proximal to the aneurysm using multiple coils. However, follow up angiograms after 6 months and 2 years demonstrated persistent retrograde filling of the left ICA aneurysm through the posterior communicating (PCOM) artery. Eventually, she was successfully treated with a flow diverter stent across the PCOM artery into the distal ICA. Follow up angiogram after 6 months showed patent flow in the PCOM artery and the distal ICA. with complete occlusion of the aneurysm. Using a flow diverter stent after insufficient parent vessel occlusion for giant intracranial aneurysms may be a feasible treatment option and an addition to the neurovascular treatment armamentarium.

Identifying Clinical Clues in Children With Global Developmental Delay / Intellectual Disability With Abnormal Brain Magnetic Resonance Imaging (MRI).

Global developmental delay / intellectual disability are common pediatric conditions. Brain magnetic resonance imaging (MRI), although an important diagnostic tool in the evaluation of these patients, often requires general anesthesia. Recent literature suggests that unnecessary general anesthesia exposure should be avoided in early years because of possible long-term negative neurodevelopmental sequelae. This study sought to identify clinical clues associated with brain MRI abnormalities in children with global developmental delay / intellectual disability in an attempt to provide guidance to physicians on selecting patients who would benefit from an MRI. Retrospective chart review analysis was conducted for patients presenting to a pediatric neurology tertiary care center between 2014 and 2017 for a first clinic evaluation for global developmental delay / intellectual disability. Detailed clinical history and physical examination findings were analyzed and correlated with brain MRI findings. The majority (218/327, 67%) of children referred for evaluation of global developmental delay / intellectual disability underwent complete clinical and radiologic evaluations. Mean age was 37.9 months (±32.5 standard deviation) and 116 were males (53%). Motor deficits were predominant in most subjects (122/218, 56%). Abnormal MRI findings were observed in 153 children (70%), with the most prevalent abnormalities noted within the white matter (104/153, 68%), corpus callosum (77/153, 50%), and the hippocampus (50/153, 33%). Abnormal MRI findings were prevalent in children with predominant motor delay (84, 69%) and cognitive disability (3, 100%) as well as those with visual and hearing impairment (P < .05). The presence of facial dysmorphisms (57/71, P = .02); cranial nerve abnormalities (79/100; P = .007) and abnormal reflexes (16, P = .01) on examination also correlated significantly with increased MRI abnormalities.

Clinical Features, Therapeutic Trends, and Outcome of Giant Prolactinomas: A Single-Center Experience Over a 12-Year Period.

BACKGROUND: Management of giant prolactinomas presents a different challenge than the management of traditional prolactinomas. OBJECTIVE: The aim of this study was to report the largest long-term single-center study of giant prolactinomas to analyze their clinical features; define epidemiological characteristics, comorbidities, complications, treatment outcomes; and to demonstrate our experience with long-term cabergoline (CAB) treatment of these giant tumors. METHODS: A retrospective case study and clinical review of patients presenting with giant prolactinomas in the pituitary clinic at King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, in the period between 2006 and 2018 were included in the study. Of the charts reviewed, 33 patients (24 men; 9 women) with age of diagnosis between 18 and 63 years (mean = 37.21 years) met the selection criteria for giant prolactinomas. RESULT: The most common presenting features include headache (87.8%), visual defects (69.7%), and hypogonadism (51.5%). The baseline means serum prolactin (PRL) level was extremely high for both sexes (95 615.03 nmol/L), which eventually decreased by as much as 95.4% after CAB treatment. Serum PRL concentrations completely normalized in 11 patients and significantly reduced in 22 patients. The mean tumor volume at baseline was 42.87 cm3, whereas the mean posttreatment tumor volume was 3.42 cm3 (no residual tumor in 2 patients, while in others, it ranged from 0.11 to 16.7 cm3) at the last follow-up visit. The mean change in tumor volume was 88.84%. Tumor volume decreased by an average of 92% for men and 80.4% for women. One patient had no tumor size change with CAB (3.5 mg thrice a week) or radiotherapy and required surgery. The response rate (remission after medical therapy alone) in this series was 84.84%. CONCLUSIONS: Findings reinforce results from our previous study that CAB provides dramatic clinical improvements with an excellent safety profile. The CAB should, therefore, be considered as the primary therapy for giant prolactinomas.

Qualitative Posttreatment Diffusion-Weighted Imaging as a Predictor of 90-day Outcome in Stroke Intervention.

PURPOSE: The aim was to assess the ability of post-treatment diffusion-weighted imaging (DWI) to predict 90-day functional outcome in patients with endovascular therapy (EVT) for large vessel occlusion in acute ischemic stroke (AIS). METHODS: We examined a retrospective cohort from March 2016 to January 2018, of consecutive patients with AIS who received EVT. Planimetric DWI was obtained and infarct volume calculated. Four blinded readers were asked to predict modified Rankin Score (mRS) at 90 days post-thrombectomy. RESULTS: Fifty-one patients received endovascular treatment (mean age 65.1 years, median National Institutes of Health Stroke Scale (NIHSS) 18). Mean infarct volume was 43.7 mL. The baseline NIHSS, 24-hour NIHSS, and the DWI volume were lower for the mRS 0-2 group. Also, the thrombolysis in cerebral infarction (TICI) 2b/3 rate was higher in the mRS 0-2 group. No differences were found in terms of the occlusion level, reperfusion technique, or recombinant tissue plasminogen activator use. There was a significant association noted between average infarct volume and mRS at 90 days. On multivariable analysis, higher infarct volume was significantly associated with 90-day mRS 3-5 when adjusted to TICI scores and occlusion location (OR 1.01; CI 95% 1.001-1.03; p = 0.008). Area under curve analysis showed poor performance of DWI volume reader ability to qualitatively predict 90-day mRS. CONCLUSION: The subjective impression of DWI as a predictor of clinical outcome is poorly correlated when controlling for premorbid status and other confounders. Qualitative DWI by experienced readers both overestimated the severity of stroke for patients who achieved good recovery and underestimated the mRS for poor outcome patients. Infarct core quantitation was reliable.

Emergent cervical internal carotid artery angioplasty before endovascular thrombectomy for acute ischemic stroke: a report of clinical and imaging outcome.

A case of tandem occlusion consisting of right internal carotid artery (ICA) origin dissection and middle cerebral artery (MCA) thromoboembolism is reported. A 45 year-old male with right-sided neurological symptoms of emergent large vessel occlusion was treated with same-session angioplasty and mechanical thrombectomy of the respective lesions. The complete neurological recovery and radiological investigations are chronicled herein, and a review of the state of tandem occlusion management is discussed.

Primary Diffuse Large B-cell Lymphoma involving the Mandible.

Lymphomas of the oral cavity are rare and typically present as intraosseous lesions that are most commonly diffuse large B-cell type. Diffuse large B-cell lymphoma (DLBCL) is an aggressive B-cell lymphoma histologically characterized by diffuse proliferation of large neoplastic B-lymphoid cells with a nuclear size equal to or exceeding normal histiocytic nuclei. A case of DLBCL of the mandible in an 18 years old male patient is presented. This report discusses this rare malignancy, including clinical presentation, histopathologic features, immunologic profile, treatment and prognosis. Though lymphoma of mandible is rare, it must be considered in differential diagnosis of swellings arising in the region.

Determinants of asthma control among children in Saudi Arabia.

OBJECTIVE: Asthma is the most common chronic disease among children. Uncontrolled asthma may considerably decrease the quality of life for patients and their families. Our objective was to identify possible risk factors for poor asthma control in children. METHODS: A cross-sectional study was conducted among children with asthma aged 4-11 years who attended a pediatric clinic for follow-up visits at one of the major teaching hospitals in Riyadh, Saudi Arabia. Asthma control status was measured by the childhood asthma control test. Multiple logistic regression analysis was performed to explore the relationships between the outcome and exposure variables. RESULTS: Uncontrolled asthma was present in 89 out of 158 children (59.3%). Asthma control improved with the number of siblings. Control improved by 69% with two or three siblings (OR = 0.31, 95% CI = 0.10-0.96) and by 87% with four or more siblings (OR = 0.13, 95% CI = 0.04-0.48). Similarly, asthma control improved with an increased asthma knowledge of the caregiver (OR = 0.87, 95% CI = 0.81-0.93). Household incomes less than SAR 15 000 and sharing a bedroom increased the odds of having uncontrolled asthma by 2.30 (95% CI = 1.02-5.21) and 3.33 (95% CI = 1.33-8.35), respectively. CONCLUSIONS: In addition to knowledge, socioeconomic factors, such as family income, household crowding, and the number of siblings are associated with asthma control among children in Saudi Arabia. Further research is needed to investigate the role of these factors.
