Clinical Features and Predictors of Mortality in Patients With Acute Pulmonary Embolism: A Retrospective Study From Southern Saudi Arabia.

BACKGROUND AND METHODOLOGY: We aimed to investigate the clinical characteristics, outcomes, and mortality predictors in patients with acute pulmonary embolism (PE). Adult patients who were admitted to the Armed Forces Hospital Southern Region, Khamis Mushait, a large tertiary hospital in Southern Saudi Arabia, with the diagnosis of acute PE were retrospectively examined for the predictors of one-year mortality. RESULTS: The overall in-hospital mortality was 15.6% among 212 patients. In univariate analysis, only age was significantly associated with increased early mortality, whereas age, obesity, presence of active malignancy, hypertension, use of thrombolytics, and Simplified Pulmonary Embolism Severity Index (sPESI) were significantly associated with increased late mortality. By use of binary logistic regression, the presence of obesity (HR 6.010, 95%CI 0.048-16.853, p=0.030), active malignancy (HR 3.040, 95%CI 1.147-8.059, p=0.025), and the use of thrombolytics (HR 8.074, 95%CI 2.719-23.977, p<0.001), were independently significant factors for late (overall) mortality, respectively. CONCLUSIONS: Among Saudi Arabian patients in the Southern Region, our data show that age is an independent factor for increased early and late mortality. The presence of obesity, active malignancy, and the use of thrombolytics, were independently significant factors for increased late (one-year) mortality. These factors should be taken into account for risk stratification and decisions on tailored management of patients with PE. Further prospective multicenter studies are needed.

Impulse control disorders in patients with dopamine agonist-treated pituitary adenomas: a cross-sectional multicenter study.

BACKGROUND: Impulse control disorders (ICDs) have been described as underrecognized side effects of dopamine agonists (DAs) in neurological disorders but are not sufficiently understood in endocrine conditions. OBJECTIVE: To identify the prevalence of DAs induced ICDs and determine potential risk factors related to these disorders in patients with prolactinoma and non-function pituitary adenomas (NFPAs). METHODS: This is a cross-sectional multicenter study involving 200 patients with prolactinoma and NFPAs, who received follow-ups in tertiary referral centers. DA-induced ICDs were assessed using ICD questionnaires modified from prior studies. RESULT: At least one ICD was reported by 52% of participants, among whom 28.5% mentioned compulsive shopping, 24.5% punding, and 24.5% hypersexuality. Furthermore, 33% of the patients reported the presence of one type of ICD behavior, while 12% specified two and 7% had three types of such behavior. The multivariable logistic regression showed that the significant risk factors of ICD were younger age (adjusted odds ratio [AOR]: 0.92, 95% confidence interval [CI]: 0.88-0.97, p 0.001), being single (AOR: 0.15, 95%CI: 0.03-0.84, p 0.03), and a positive history of psychiatric illness (AOR: 7.67, 95% CI: 1.37-42.97, p 0.021). CONCLUSION: ICDs with a broad range of psychiatric symptoms are common in individuals with DA-treated prolactinoma and NFPAs. Endocrinologists should be aware of this potential side effect, particularly in patients with a personal history of psychiatric disorder.

Assessment of calcium intake and recognition of calcium-rich food sources among the Saudi population.

Calcium is an essential skeletal mineral, and calcium deficiency has a negative impact on bone health. We conducted an online questionnaire to assess the intake and knowledge among the Saudi population. The survey included 950 participants, with 51.1% demonstrating poor knowledge of calcium sources and a mean intake lower than the recommended level. INTRODUCTION: Calcium is an essential mineral and one of the most prevalent in the body. Chronic insufficient calcium intake increases the risk of osteopenia, osteoporosis, and bone fracture. PURPOSE: This study aimed to assess the Saudi population's calcium intake and knowledge of calcium sources as well as to identify factors associated with inadequate calcium intake. METHODS: This cross-sectional study was conducted across Saudi Arabia using an online questionnaire distributed randomly through social media channels. The questionnaire was a validated tool that was previously developed and used by the original author to assess knowledge of calcium food sources and estimate calcium intake in the Saudi population. If an individual answered more than 11 questions correctly, calcium knowledge was considered adequate. Calcium intake was considered sufficient or insufficient based on the recommended dietary allowance (RDA) of 1000 mg/day. RESULTS: The survey included male and female Saudi citizens and residents aged 14 years or older. A total of 950 respondents aged 9-70 completed the questionnaire. A total of 62.9% of the respondents were 26-50 years old. Of the participants, 64.2% were female, 71.7% were married, and 61.9% had a diploma or a bachelor's degree. Of these, 63.8% were from the central region, and 97.6% were from Saudi Arabia. For those aged 9-18, the average calcium consumption was 577 mg/day, whereas it was 479 mg/day for those aged 19-50. The average intake was 479 mg/day for males aged 51-70 (EAR = 1000 mg/day) and 438 mg/day for females (EAR = 1200 mg/day). These calcium consumption values were significantly lower than the estimated average requirement (EAR) and RDA (p < 0.01). Correct response rates for the 19 calcium intake knowledge items ranged from 23.4 to 94.7%. Among the participants, 48.9% had significant calcium intake knowledge, as indicated by a score of > 11 out of 19 correct responses. Age, sex, marital status, educational attainment, and residence were significantly correlated with adequate knowledge of calcium. Demographic characteristics such as age, marital status, and residence were associated with sufficient calcium intake in the study. CONCLUSION: The study findings revealed that a significant proportion (51.1%) of participants demonstrated inadequate knowledge regarding calcium food sources. Additionally, the mean calcium intake was found to be lower than the RDA of 1300 mg/day for males and females 14-18 years old and 1000 mg/day for males and females 19-50 years old and males 51-70 years old; however, the RDA for females 51-70 years old is 1200 mg/day, suggesting an urgent need for interventions aimed at enhancing both calcium knowledge and intake.

Expression of IFN-Gamma is significantly reduced during severity of covid-19 infection in hospitalized patients.

Cytokines play an important role in SARS-CoV-2 infection progression and severity. A number of inflammatory cytokines have been directly associated with disease severity including IL-6 (interleukin-6), IL-10, TNF-α (tumor necrosis factor alpha), IFN-γ (interferon-gamma). Here, in this study, the aim was to better understand the interplay between host immune response mediated by cytokines and severity of SARS-CoV-2 infection by assessing cytokine expression. Therefore, we measured expression levels of a total of 12 genes (IFNA-1, IFN-γ, IL-1α, IL-1ß, IL-4, IL-6, IL-7, IL-10, IL-11, IL-13, IL-15, and IL-27) encoding inflammatory, anti-inflammatory and regulatory cytokines using QRT-PCR in hospitalized patients with severe infection compared to mildly infected. IFN-γ was identified as a potent marker of disease severity as indicated previously. Moreover, levels of IL-7 were also found to be partially reduced in patients compared to the healthy controls and linked negatively to disease severity. Identification of these cytokines may be helpful in not only understanding disease pathogenesis but also in better management of the patients after covid infection.

Diagnosis and management of osteoporosis in Saudi Arabia: 2023 key updates from the Saudi Osteoporosis Society.

The Saudi Osteoporosis Society (SOS) has updated its guidelines for the diagnosis and management of osteoporosis in Saudi Arabia (SA), with emphasis on postmenopausal women. This document is relevant to all healthcare professionals in SA involved in the care of patients with osteoporosis and osteoporosis-related fractures. INTRODUCTION: The SOS launched the first national osteoporosis guidelines in 2015 and spearheaded the Gulf Cooperation Council Countries (GCC) osteoporosis consensus report in 2020 which was under the auspices of the European Society for Clinical and Economic Aspects of Osteoporosis (ESCEO). This paper highlights a major update of the guidelines in the SA setting. METHODS: This guideline is an adaptation of the current guidelines derived from ESCEO, the American Association of Clinical Endocrinologists (AACE), and the GCC osteoporosis consensus report and studies on osteoporosis done in SA. Where accessible, the timeliest systematic review, meta-analysis, and randomized controlled trials were used as evidence. RESULTS: The present update includes new recommendations for the assessment of osteoporosis taking into consideration the Saudi model of FRAX for fracture probabilities, appropriate doses for the maintenance of vitamin D status and calcium, the use of representative blood analytes for therapy monitoring, the use of romosozumab and sequential therapy in the pharmacological management strategies, and the establishment of fracture liaison services to prevent secondary fractures. CONCLUSION: This updated guideline is for all healthcare professionals involved in osteoporosis and post-fracture care and management in SA and harmonized the most up-to-date changes in the field based on evidence-based medicine for use in the local setting.

Use of the Osteoporosis Self-Assessment Tool as a Screening Tool for Osteoporosis in Saudi Postmenopausal Women.

BACKGROUND: Osteoporosis is commonly referred to as the "silent disease," as bone loss is gradual and asymptomatic. In older women and men, osteoporosis can lead to increased bone fragility, thus increasing the risk of fractures. These fractures are associated with healthcare costs, physical disabilities, impaired quality of life, and mortality. Therefore, the study's main objective was to assess the applicability of the osteoporosis self-assessment tool (OST) in predicting osteoporosis in Saudi postmenopausal women who are 60 years of age and older and to give a thorough understanding of how such a method can aid in the early diagnosis of osteoporosis in Saudi Arabia and give physicians enough time to treat it.  Methods: This study was done at King Abdulaziz Medical City, Riyadh, Saudi Arabia, where we included postmenopausal Saudi women 60 years of age and older who took the bone mineral density (BMD) test in the family medicine department. The approximate target population in this group, between the years 2016 and 2022, was 2969 patients. All data was taken from the BestCare database at King Abdulaziz Medical City in Riyadh. Data were typed in an Excel sheet (Redmond, USA), then transferred to the R Studio software. The data collection method was chart review, so no informed consent was needed from patients. Names and medical record numbers were not stored.  Results: The study included 2969 participants. According to the bone mineral density (BMD) T score results, 490 participants (16.5%) were normal, 1746 participants (58.8%) had osteopenia, and 733 participants (24.7%) suffered from osteoporosis. BMD T scores for normal, osteopenia, and osteoporosis participants were -0.6 (-0.9, -.3), -1.8 (-2.1), and -3 (-3.5, -2.7), consecutively. Estimated OSTI scores for those patients were 2 (0, 4), 1 (-2, 3), and -1 (-4, 1), consecutively. According to the OSTI score for normal participants, 4.29% were classified as being at high risk of osteoporosis. A high risk of osteoporosis was identified in 0.74% of those with osteopenia. 27.83% of osteoporosis patients were classified as being at high risk of osteoporosis. To differentiate normal individuals from those with osteopenia, the cutoff value with optimal sensitivity was 3.5. At such a cutoff value, the test sensitivity was 81.04%. To differentiate normal participants from those with osteoporosis, the cutoff value with optimal sensitivity was 2.5. At such a cutoff value, the test sensitivity was 86.49%. To differentiate osteopenia from osteoporosis patients, the cutoff threshold with optimal sensitivity was 1.5. At such a threshold, sensitivity was 78.44%.  Conclusion: OSTA is a simple and validated tool that can identify subjects at increased risk of osteoporosis. Its use could facilitate a more cost-effective use of BMD; by avoiding measurements in low-risk groups.

The Assessment of the Prevalence and Disability Severity of Musculoskeletal Pain in Patients With Multiple Sclerosis in Saudi Arabia.

Background Multiple sclerosis (MS) is an autoimmune disease of the nervous system that causes chronic demyelination over time and may lead to physical disability. MS-related pain may be musculoskeletal, paroxysmal, or persistently neurogenic in nature. The most common type of pain is musculoskeletal discomfort, which is typically brought on by muscle weakening, stiffness, and generalized imbalance as the condition progresses. Pain often manifests after prolonged immobilization of muscles, tendons, and ligaments. Aim We aimed to evaluate the prevalence and severity of musculoskeletal pain (MSP) among MS patients in Saudi Arabia. Methodology A quantitative cross-sectional study was conducted. Patients with confirmed MS in Saudi Arabia were invited to participate in the study during the duration from April 2022 to May 2022. Data were collected using an electronic collection tool. The study tool was checked to ensure the content validity and clarity of the Arabic and English versions. Results A total of 360 MS patients were included. Patients' ages ranged from 18 to 65 years with a mean age of 34.9±13.2 years old. Exactly 229 (63.6%) patients were females. A total of 104 (28.9%) patients complained of relapsing-remitting MS, 34 (9.4%) complained of primary progressive MS, and 16 (4.4%) complained of secondary progressive MS. A total of 138 (38.3%) patients had the disease for less than five years, and 14 (3.9%) had the disease for more than 21 years. Exactly 124 (34.4%) MS patients complained of high disability due to MSP, while 236 (65.6%) had low disability. Conclusions This study demonstrates that one out of each three patients with MS complained of pain with high disability associated with pain. Old age, comorbidities, long disease duration, and a family history of MS were significant determinants of associated disability severity.

Effects of the Cervical Marginal Relocation Technique on the Marginal Adaptation of Lithium Disilicate CAD/CAM Ceramic Crowns on Premolars.

AIM AND OBJECTIVE: To evaluate the effect of cervical margin relocation (CMR) for crowns designed using CAD/CAM technology and fabricated from lithium disilicate (e.max, CAD) before and after aging; and to compare the fracture forces and failure type of the tested crowns. MATERIALS AND METHODS: Mesio-occluso-distal(MOD) cavities 1 mm above the cementoenamel junction(CEJ) were prepared on 40 maxillary first premolars. The teeth were divided into four groups. In group A, all cervical margins (CM) were located 1 mm above the CEJ. However, in both mesial and distal proximal boxes of groups B, C, and D, in addition to the MOD cavities, the CMs were extended 2 mm on both sides below the CEJ apically to simulate the CMR technique. In group B, the mesial and distal proximal boxes were filled with flowable composite, while for group C and group D, specimens were filled with composite resin fillings. To simulate the CMR technique, the cavities were filled with composite layers of 3 mm in two increments. Using the CAD/CAM system, 40 standard crowns were prepared on premolars, then cemented using a dual-curing adhesive cement. Assessments of the marginal integrity of interfaces of the proximal boxes of the cemented crowned teeth were recorded. Statistical differences between groups were analyzed using the ANOVA and Bonferroni's posthoc test. RESULTS: The first null hypothesis was accepted since no statistically significant differences were found in marginal integrity before and after aging (p>0.05), while the second was partially rejected since different fractured force values were recorded and a significant difference was detected between group D and group B. The third hypothesis was rejected because the catastrophic fracture rate was the highest among the four groups. CONCLUSION: The implementation of CMR before and after aging had a good effect on the marginal integrity of CM relocation. The CMR technique with resin luting cement of lithium disilicate crowns is effective and recommended for the restoration in deep proximal boxes of premolars or posterior teeth. CLINICAL SIGNIFICANCE: CAD/CAM-generated e. max all-ceramic crowns with composite as the CMR enable the reconstruction of severely destroyed teeth irrespective of the position of the cavity margins.

A qualitative study of prescribing errors among multi-professional prescribers within an e-prescribing system.

Background Computerised Physician Order Entry (CPOE) is considered to enhance the safety of prescribing. However, it can have unintended consequences and new forms of prescribing error have been reported. Objective The aim of this study was to explore the causes and contributing factors associated with prescribing errors reported by multidisciplinary prescribers working within a CPOE system. Main Outcome Measure Multidisciplinary prescribers experience of prescribing errors in an CPOE system. Method This qualitative study was conducted in a hospital with a well-established CPOE system. Semi-structured qualitative interviews were conducted with prescribers from the professions of pharmacy, nursing, and medicine. Interviews analysed using a mixed inductive and deductive approach to develop a framework for the causes of error. Results Twenty-three prescribers were interviewed. Six main themes influencing prescribing were found: the system, the prescriber, the patient, the team, the task of prescribing and the work environment. Prominent issues related to CPOE included, incorrect drug name picking, default auto-population of dosages, alert fatigue and remote prescribing. These interacted within a complex prescribing environment. No substantial differences in the experience of CPOE were found between the professions. Conclusion Medical and non-medical prescribers have similar experiences of prescribing errors when using CPOE, aligned with existing published literature about medical prescribing. Causes of electronic prescribing errors are multifactorial in nature and prescribers describe how factors interact to create the conditions errors. While interventions should focus on direct CPOE issues, such as training and design, socio-technical, and environmental aspects of practice remain important.

Frequency of Color Vision Deficiency among Saudi Dental Students: A Cross-Sectional Study.

OBJECTIVE: The current research was conducted to evaluate the frequency of color-vision deficiency among dental students of King Khalid University College of Dentistry, Saudi Arabia. MATERIALS AND METHODS: A cross-sectional study was performed among 203 dental students working as interns at male and female dental clinics of King Khalid University College of Dentistry (KKUCOD), Saudi Arabia. The Ishihara color-vision deficiency (CVD) test with 24 plates was used for diagnosis of the problem. Analysis of the data was done by performing Chi-square tests using SPSS software version 20. RESULTS: The frequency of total CVD was found to be 3.9%. While the association of gender with total CVD was observed to be statistically nonsignificant, a statistically significant relation was drawn with red-green color deficiency. Out of the total of 203 patients, 44 males were identified with red-green color deficiency, whereas only three females were found to have this condition, therefore revealing that CVD is more prevalent in males. Age was found to have a significant association with red-green color vision deficiency, protanopia, and total CVD. CONCLUSION: A total of 20.19% male dental students had red-green color vision deficiency compared to 1.4% in female students. The dental students must be aware of their congenital color vision deficiency and its impact on their professional life. Screening of such dental students and professionals is quite important so that they can tackle the color vision problems well without having detrimental effect on their future dental practice.

Giant Unruptured Internal Carotid Artery Aneurysm.

Headache is among the most frequent symptoms to seek medical care. Careful evaluation by history-taking and appropriate physical examination is needed to exclude the potential secondary causes of headaches. In the elderly population, secondary headaches are more prevalent compared with the younger adult population. We present the case of a 70-year-old man who presented with a three-month history of headache with visual disturbances. He reported that this was the first time he experienced such a headache. The patient had a longstanding history of hypertension, diabetes mellitus, dyslipidemia, and ischemic heart disease. He was a heavy smoker with a 35 pack-years smoking history. In view of the clinical signs and symptoms, the patient underwent a computed tomography scan that revealed a right internal carotid artery aneurysm. For better evaluation, magnetic resonance imaging of the brain was performed and re-demonstrated the saccular aneurysm of the terminal part of the right internal carotid artery aneurysm, measuring 48 x 37 x 31 mm and partially thrombosed with a surrounding mural hematoma. The neck of the aneurysm measured 4 mm. The decision for surgical management was planned. The patient underwent craniotomy with surgical clipping of the aneurysm. No complications occurred during the operation. The patient had an uneventful recovery. Elderly patients with chronic headaches should be carefully evaluated for secondary headaches. A giant cerebral artery aneurysm is an uncommon etiology of secondary headache that needs prompt diagnosis and management.

Assessment of calcium intake and perception of calcium-rich food among healthcare students at King Saud bin Abdulaziz University for Health Science (KSAU-HS).

BACKGROUND: Calcium is an essential mineral compound and one of the most abundant minerals in the human body. A long-term low calcium intake predisposes the bones to fractures, osteopenia, and osteoporosis. This study was conducted to assess calcium intake and knowledge of calcium-related information among healthcare students in King Saud bin Abdulaziz University for Health Sciences (KSAU-Hs). METHODS: This cross-sectional survey was conducted using a self-administered questionnaire that has been distributed as a soft copy of 289 participants aged 19 years or older and studied at KSAU-Hs. The questionnaire had three sections assessing demographical data, calcium knowledge, and calcium intake. The knowledge outcome variables were good and poor, and participants were categorized as good knowledge if they answer 11 or more of the 18 questions, while the intake outcome variables were sufficient and insufficient intake based on the Recommended Dietary Allowance (RDA) of 1000 mg. RESULTS: Among all variables, 91.7% of the participants were found to be having an insufficient intake, and 74% were classified to be poor knowledge. As for knowledge, the highest score under the "Good" category were females 32.7% compared to males 22.2%, P = 0.05. The average intake of calcium was 497 mg/day. In terms of sufficient calcium intake, males scored 11.9% compared to females who scored 1.9% with a P value of 0.00. CONCLUSION: The results of this study have shown that there are significantly insufficient calcium intake and poor knowledge about calcium among healthcare students. The results indicate the urge to improve calcium intake and calcium knowledge among the healthcare students.

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.

Management of acromegaly: an exploratory survey of physicians from the Middle East and North Africa.

BACKGROUND: Worldwide variations exist in the diagnosis and management of patients with acromegaly. For such a rare condition, the knowledge and perception of physicians would most likely direct the care of patients. However, the adherence of physicians in non-Western regions to guidelines for the diagnosis and management of acromegaly has not been previously ascertained. METHODS: An online survey was conducted to assess the perceptions and practice of physicians regarding acromegaly diagnosis and management as per international guidelines. An electronic questionnaire containing key questions was mailed, initially to physicians in Saudi Arabia (KSA) and later to other countries in the Middle East and North Africa (MENA) region. Additional questions were included to ensure the relevance of the respondents' replies. The responses were captured and summarized anonymously. Descriptive comparisons were made with two similar international and national surveys from other regions. RESULTS: Two hundred forty-seven doctors responded to the survey. Of these, 155 (64.5%) fulfilled the inclusion criteria and, in particular, confirmed having treated acromegaly patients in the previous 12 months, and they constituted the basis of this study. The three most common referring specialties for patients were internists (44; 28.4%), neurosurgeons (46; 29.6%), and family medicine physicians (42; 27.1%), respectively. The combination of growth hormone (GH) nadir during the oral glucose tolerance test (OGTT) and elevated insulin-like growth factor-1 (IGF-1) levels was used by 99 physicians (63.9%) to diagnose acromegaly. The main determinant for treatment choice was tumor mass characteristics confirmed by 117 respondents (75.5%) with neurosurgery as first treatment choice confirmed by 124 respondents (80%). Combined measurement of IGF-1 and GH levels after OGTT at 3 months after surgery was the most widely used criterion for assessment of surgical outcomes, confirmed by 82 physicians (52.9%). The biggest barriers to optimal management of acromegaly as perceived by 38.1% and 35.5% of the respondents were high cost of medications and lack of physicians' awareness, respectively. CONCLUSIONS: The majority of the surveyed physicians reported variable adherence to the international acromegaly guidelines. Clearly, higher awareness is needed among physicians for early diagnosis and timely referral for specialist management.

Assessment of Ramadan Education and Knowledge Among Diabetic Patients.

BACKGROUND: During Ramadan, Muslims fast from dawn until dusk for one lunar month every year. Most of the Muslim patients with diabetes are unaware of the potential complications that can occur while fasting, such as hypoglycemia. The aim of this study is to assess the the patient education level and patients' overall awareness of any possible complications that could occur while fasting during Ramadan and to determine how these patients deal with these complications. METHODS: We conducted a cross-sectional study and surveyed diabetic patients about their diabetes-related knowledge over a period of 4 months from the outpatient clinic at the Obesity, Endocrine, and Metabolism Center at King Fahad Medical City. Patients were included if they were ≥16 years and if they had been receiving treatment for at least 1 year before the study, irrespective of the medications used; patients were also asked about the presence or absence of complications. RESULTS: This study included 477 patients (325 women and 152 men). Most patients (297; 62.3%) had type 2 diabetes. The patients' mean age was 39.72 ± 15.29 years, and the mean duration of diabetes was 10.80 ± 5.88 years. During the preceding Ramadan, 76% of patients reported fasting, whereas 58% said that they monitored their blood glucose levels once per day. Hypoglycemic episodes were reported in 60.3% of cases with type 2 diabetes and in 8.3% of cases with type 1 diabetes. Among those who had hypoglycemia, 2.8% of patients with type 1 diabetes and 17.8% with type 2 diabetes broke their fast. Finally, 54% of patients reported that their health care providers offered them instructions on diabetes management during Ramadan. CONCLUSIONS: Ramadan health education in diabetes can encourage, improve, and guide patients to change their lifestyles during Ramadan while minimizing the risk of acute complications.

Public knowledge and awareness about Parkinson's disease in Saudi Arabia.

BACKGROUND: Parkinson's disease (PD) is one of the most prevalent neurologic disorders, leading to progressive disability that can be slowed but not stopped by treatment. It is characterized by tremors, slow movements, stiffness in arms and legs, and balance impairment. Despite advancement in treatment, diagnosis, and care of PD patients, lack of adequate knowledge and associated beliefs among the community might have a key role in limiting access to proper treatment and care. OBJECTIVES: To identify the level of awareness of our population regarding PD in terms of causes, signs, symptoms, and treatment. MATERIALS AND METHODS: A cross-sectional study was conducted on Saudis, who have active Twitter accounts. Data were collected through a previously validated questionnaire, which tests recognition of PD symptoms and general knowledge regarding PD. The questionnaire was translated into Arabic. Part 1 of the questionnaire is the demographic data collection sheet, Part 2 of the questionnaire tests recognition of PD symptoms, and Part 3 of the questionnaire tests general knowledge regarding PD. RESULTS: The questionnaire was administered to 3,050 members of the public, of which 2,609 questionnaires (86.20%) were included in the analysis. The tremor was the most widely recognized symptom (86.10%), and weight loss was the most recognized non-motor symptom (24%). Most respondents (56%) were able to identify imbalance as a symptom of PD, whereas only 4.10% of them were able to identify the reduced sense of smell as a symptom of PD. Motor symptoms were significantly better recognized (range 31.30%-86.10%) than non-motor symptoms (range 4.10%-24%). CONCLUSION: Educational campaigns may be appropriate to improve public awareness of PD and individual knowledge about PD symptoms and treatment.

Temozolomide therapy for resistant prolactin-secreting pituitary adenomas and carcinomas: a systematic review.

Pituitary tumors represent 10-15% of all intracranial tumors; of these, prolactinomas account for 40-50% of cases. Prolactinomas usually respond well to dopamine agonists (DA) as first-line therapy. However, treatment resistance remains a concern. Temozolomide (TMZ) is an oral alkylating agent that has shown promise in treating aggressive pituitary adenomas and carcinomas that are resistant to other therapies. To date, no control trials have been undertaken and only single case reports of pituitary tumors treated with TMZ have been published. A systematic literature search was conducted for studies reporting the use of TMZ for the treatment of prolactinomas that were resistant to standard therapy. In total, 42 reported cases were identified and included in our analysis: 23 cases of prolactin-secreting adenomas and 19 of prolactin-secreting carcinomas. Prior to TMZ administration, patients had exhibited tumor progression and had previously undergone various treatments including surgery, radiotherapy, and drug therapy. Tumor shrinkage was reported in 76% of patients. Reduced prolactin levels were observed in 75% of patients, while normalization of prolactin was reported in 8%. TMZ failure occurred in 20.6% of cases. Most patients exhibited no serious adverse effects. In conclusion, TMZ has potential for the treatment of highly aggressive and resistant prolactin-secreting adenomas and carcinomas, as demonstrated by tumor shrinkage or complete response and normalization of hormone hypersecretion, and exhibits good tolerability and few side effects.
