Outcomes of central nervous system tuberculosis in Saudi Arabia: a multi-center study.

OBJECTIVES: Central nervous system tuberculosis (TB) (CNS-TB) can occur in several forms, including intracranial tuberculoma, tuberculous brain abscess, TB meningitis (TBM), and spinal TB. Early treatment can save lives and prevent severe neurological complications. This study aimed to describe the characteristics and post-treatment outcomes of patients with CNS-TB and identify factors associated with poor outcomes. To the best of our knowledge, this is the largest CNS-TB study till date published in Saudi Arabia. METHODS: This retrospective cohort study included all patients diagnosed with CNS-TB in three tertiary centers in Saudi Arabia (King Abdulaziz Medical City in Jeddah, King Abdulaziz Medical City in Riyadh, and Al-Noor Specialist Hospital in Makkah) between 2009 and 2019. Data of patients' demographics, co-morbidities, presenting symptoms, type of CNS-TB, medical and surgical treatments, and outcome after completion of treatment were obtained from medical records. Treatment outcomes were categorized using the modified Rankin Scale for neurological disability. RESULTS: A total of 140 participants were included in this study from 2009 to 2019. Good outcomes were achieved in approximately 65% of cases, whereas 35% had poor outcomes based on the modified Rankin Scale. Glasgow Coma Scale score ≤10 at presentation and TBM/tuberculoma were significantly associated with poor outcomes. Moreover, the use of corticosteroids, more than three anti-TB medications, and surgical interventions were not significantly associated with good or poor outcomes. DISCUSSION: CNS-TB is associated with a high burden of long-term neurological morbidity. Early detection and treatment are crucial to prevent serious complications and decrease morbidity and mortality.

Patterns of multiple sclerosis presentation to the emergency department.

Background: Multiple sclerosis (MS) patients are no strangers to the emergency department (ED) due to the relapsing and progressive nature of the disease and the associated complications. This study aimed to identify patterns of ED visits among patients diagnosed with MS, the underlying causes of these visits, and the factors associated with these visits. Methods: This was a single center retrospective cohort study which utilized a non-probability consecutive sampling technique to include all patients diagnosed with MS (471 patients) from March 2016 to October 2021 in King Abdulaziz Medical City, Jeddah, Saudi Arabia. ED visits were categorized as directly related to MS, indirectly related to MS, or unrelated to MS. Results: One in four people with MS visited the ED at least once with a total of 280 ED visits. Most ED visits were ones directly related to MS 43.6%, closely followed by unrelated to MS 41.1%, and then indirectly-related MS visits 15.4%. The most common presenting symptoms in directly-related MS visits were weakness 56.6% and numbness/tingling 56.6% followed by gait impairment 29.5%. Indirectly related to MS or unrelated to MS ED visits were commonly due to neurological 17.7% and gastrointestinal 17.1% causes. Using disease modifying therapy (DMT) was significantly associated with no ED visits (p < 0.001). The use of high-efficacy DMTs was significantly associated with no ED visits than using moderate efficacy DMT (p < 0.001). The use of B-cell depleting therapy (ocrelizumab and rituximab) was significantly associated with no visits to the ED than using any other DMT (p < 0.001). Evidence of brain atrophy on imaging was significantly associated with patients who presented to the ED ≥3 times (p = 0.006, UOR = 3.92). Conclusion: Due to the nature of the disease, many MS patients find themselves visiting the ED due to MS related and unrelated issues. These patients are not only required to be treated by neurologists but also by multiple disciplines. The use of high-efficacy DMTs and B-cell depleting therapy may reduce the total frequency of ED visits. Special attention should be paid to patients who have evidence of brain atrophy on imaging.

Assessment of Quality of Life (QoL) of Colorectal Cancer Patients using QLQ-30 and QLQ-CR 29 at King Abdulaziz Medical City, Jeddah, Saudi Arabia.

Objective: We aimed to assess the quality of life (QoL) and its predictors in colorectal cancer (CRC) patients at King Abdulaziz Medical City, Jeddah. Methods: A total of 118 CRC patients at King Abdulaziz Medical City, a tertiary hospital in Jeddah, participated in this study. The participants were provided with the online questionnaire via WhatsApp by trained researchers and data collectors in February 2021. All participants were required to answer the three-section questionnaire comprising of (a) demographic data and a validated Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaires, (b) a general version (QLQ-30), and (c) a CRC-specific version (QLQ-CR29). Results: Statistical analysis revealed that the most common comorbidity among the participants was diabetes mellitus (42.4%). In addition, the mean global health status was 63.91 ± 24.75. For the global health tool QLQ-C30, results exhibited that physical functioning [62.94 (30.04)] and social functioning [63.56 (31.95)] scored below the threshold, while the cognitive functioning scale scored the highest [74.86 (25.11)]. In addition, on the QLQ-C30 scales, fatigue and insomnia were distressing, with fatigue scoring the highest. For the disease-specific tool QLQ-CR29, it was found that for the symptom scale, urinary frequency and embarrassment scored the highest. Conclusion. The participants reported high global quality of life on both the EORTC QLQ-30 and QLQ-CR29 scales. This study identifies the factors and predictors that affect the quality of life of CRC patients in Saudi Arabia. Recognizing these factors and predictors may empower those patients to maintain positive perception towards the impact of colorectal cancer and improve their survival.

Treatment response among asthmatic patients with and without reversible airflow limitations.

OBJECTIVES: Asthma is a chronic airway disorder associated with variable airflow limitations, which are triggered by different stimuli. The reversibility of airflow limitations reflects patients' responses to the therapy with bronchodilators and improvements in airflow. This study aims to determine the treatment outcomes (improvements in forced expiratory volume in the first second (FEV1) and the number of asthma exacerbations) associated with the presence of airflow reversibility. METHODS: This retrospective cohort study included 154 adults (>18 years) who were diagnosed with asthma and had pulmonary function testing (PFT) at a tertiary care centre in KSA between January 1st, 2014 and May 31st, 2019. Smokers and patients with comorbidities or medications that could affect PFT were excluded from the analysis. Patients were classified as having a reversible airflow limitation when they exhibited a post-bronchodilator FEV1 increase of 12% and 200 mL. Exacerbations were defined as the need to use oral corticosteroids. Chi-square tests were used for comparative analyses. RESULTS: From our cohort, 42 patients exhibited reversibility. In contrast, 112 patients did not show any sign of reversibility. Asthmatics with baseline reversible airflow limitations experienced significant worsening of FEV1 during the follow-up period compared with those with no reversibility, showing a mean difference of 19.96 mL (p = 0.0206). There was no significant association between asthma reversibility and exacerbations (p = 0.23). CONCLUSION: In our study, during the follow-up of patients with asthma, we found that the reversibility of airflow was associated with significantly worse FEV1, although this did not have a significant effect on exacerbations. Therefore, we recommend regular spirometry follow-ups, particularly for patients with significant airway reversibility.

Central nervous system vasculopathy and Seckel syndrome: case illustration and systematic review.

PURPOSE: To systematically review reported cases of Seckel syndrome (SS) and point out cases associated with central nervous system (CNS) vasculopathy and provide a summary of their clinical presentation, management, and outcomes including our illustrative case. METHODS: We conducted a search on the MEDLINE, PubMed, Google Scholar, and Cochrane databases using the keywords "Seckel + syndrome." We identified 127 related articles reporting 252 cases of SS apart from our case. Moreover, we searched for SS cases with CNS vasculopathies from the same databases. We identified 7 related articles reporting 7 cases of CNS vasculopathies in SS patients. RESULTS: The overall rate of CNS vasculopathy in SS patients is 3.16% (n = 8/253), where moyamoya disease (MMD) accounted for 1.97%. The mean age is 13.5 years (6-19 years), with equal gender distribution (M:F, 1:1). The most common presenting symptoms were headache and seizure followed by weakness or coma. Aneurysms were mostly located in the basilar artery, middle cerebral artery, and internal carotid artery, respectively. Regardless of the management approach, 50% of the cases sustained mild-moderate neurological deficit, 37.5% have died, and 12.5% sustained no deficit. CONCLUSION: A high index of suspicion should be maintained in (SS) patients, and MMD should be part of the differential diagnosis. Prevalence of CNS vasculopathy in SS is 3.16% with a much higher prevalence of MMD compared to the general population. Screening for cerebral vasculopathy in SS is justifiable especially in centers that have good resources. Further data are still needed to identify the most appropriate management plan in these cases.

Complications of White-coat Hypertension Compared to a Normotensive and Hypertensive Population.

BACKGROUND: Accumulating evidence demonstrates that white-coat hypertension (WCH) are associated with several risks and complications. In this study, we aimed to investigate the adverse effects of WCH compared with hypertensive and normotensive patients. METHODS: A retrospective cohort study was conducted over five years. Blood pressure (BP) data was collected from both clinic visits and 24-h ambulatory blood pressure monitoring (ABPM) reports. Epidemiological data and complications, cardiac and noncardiac, were also recorded. RESULTS: In total, 286 participants who were followed up for at least three years were included. The sample was divided into 99 normotensive patients (as a control group), 94 patients with clinically diagnosed hypertension (HTN), and 93 patients with WCH. Ischemic heart disease (IHD) was the most noted complication in the WCH group with a relative risk of 9.58 (1.23-74.16) (P = 0.008). Acute coronary syndrome (ACS) was significantly correlated with a relative risk of 2.06 (0.52-13.38). No significant correlation was noted with noncardiac complications. Both HTN and WCH groups showed a significant association with blood pressure variability (BPV). WCH was associated with an increased BPV in ambulatory daytime systolic measurements (P = 0.031) and a unique increase in diastolic measurement variability in office BP measurements (P = 0.020). CONCLUSION: WCH should be managed as HTN. WCH is associated with cardiac complications, particularly IHD, specifically in patients 55 years and older. WCH was significantly associated with a higher BPV in both ABPM and office-based measurements.

Types of Glaucoma and Associated Comorbidities Among Patients at King Abdulaziz Medical City, Jeddah.

Aim To identify the types of glaucoma and associated comorbidities among patients attending the ophthalmology clinic at King Abdulaziz Medical City (KAMC) in Jeddah. Methods A cross-sectional study that included all glaucoma patients at KAMC in Jeddah between June 1st, 2016 and November 30th, 2020. Data were collected through retrospective chart review from the electronic medical record system (BestCare) and utilized a structured data collection sheet. Results A total of 283 patients met the inclusion criteria. The most common type was primary open-angle glaucoma (POAG; 53%) followed by secondary glaucomas (SG; 26.5%) then childhood glaucoma and primary angle-closure glaucoma (CG, PACG; 7.4%). The majority of secondary glaucoma cases were due to neovascular glaucoma (NVG; 44.9%), followed by phacomorphic glaucoma (17.9%) and phacolytic glaucoma (10.3%). Hypertension (60.8%) and diabetes (58.3%) were the most prevalent systematic comorbidities, and cataract (49.1%) was the most prevalent ocular comorbidity. Conclusion POAG was the most common glaucoma type, followed by SG, CG, and PACG. Among secondary glaucoma types, neovascular glaucoma was found to be the most common subtype. Hypertension was the most prevalent comorbid condition.

Association Between Vitamin D and Zinc Levels With Alopecia Areata Phenotypes at a Tertiary Care Center.

Objectives Alopecia areata (AA) is a common immune-mediated hair disorder that presents in different clinical patterns. This study aims to find the association between vitamin D and zinc levels with AA phenotypes, to determine the common comorbidities in AA patients, and to assess the influence of age, gender, and body mass index (BMI) on AA phenotypes. Methods This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected through retrospective chart review of the electronic medical record system (BestCare) and by utilizing a structured data collection sheet. Results A total of 177 patients were clinically diagnosed with AA with a mean age of 28.37 ± 12.68 years. The mean vitamin D level was 49.14 ± 29.09 nmol/L. Zinc levels were reported in only 22 patients, among which, only one patient had deficient levels. The mean zinc level was 9.8 ± 1.5 µmol/L. Patchy alopecia areata (60.45%) was the most common phenotype followed by universalis (9%) and totalis (7%). Hypothyroidism (11.8%) was the most prevalent comorbidity followed by atopic diseases (10.7%), then both diabetes and mood disorders (6.2%). Conclusion Deficient serum vitamin D levels were present in 62.7% of patients with AA. Nevertheless, no statistically significant relation was detected between vitamin D status and patterns of alopecia areata (P=0.108). A limited number of our sample had records of zinc levels with a mean serum of 9.8 ± 1.5 µmol/L and only one patient was found to be deficient.

Patterns of Comorbidities in Psoriasis Patients: A Cross-Sectional Study.

BACKGROUND: Psoriasis is a chronic, inflammatory, and immune-mediated dermatological disease of unknown etiology with predominant involvement of the skin, nails, and joints. This study aimed to assess comorbidities patterns in psoriasis patients. METHODS: This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected through a retrospective chart review of the electronic medical record system (Bestcare, Ezcaretech, Seoul, Korea) and by utilizing a structured data collection sheet. RESULTS: A total of 128 confirmed psoriasis cases were included with a mean age of 44.2 ± 17.3. The sample had 45.7% females and 54.3% males. Nearly half the patients (46.1%) had no comorbidities, followed by those who had at least one comorbidity (24.2%) and those who had two or more comorbidities (29.7%). Most patients were classified as plaque psoriasis (57.0%), followed by those who had psoriatic arthritis (13.3%). There was no statistical significance between gender, body mass index (BMI), and smoking with the number of comorbidities (P= 0.422, P=0.361, P=0.772); 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which is statistically significant at p-value <0.018. CONCLUSION: This study demonstrated the prevalence of different comorbidities associated with psoriasis patients; 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which was statistically significant. This necessitates closer monitoring of different comorbidities a psoriasis patient might present with. Especially those who are diagnosed with psoriatic arthritis and erythrodermic arthritis.

A Systematic Review of Screw versus Cement-Retained Fixed Implant Supported Reconstructions.

PURPOSE: Dental implant is an effective and standardized treatment procedure in the healthcare setting. This study presents a comparison of dental implant reconstruction using screw and cement. It explicitly reviews the studies concerning cement and screws dental implants to determine the efficiency of the two. PATIENTS AND METHODS: A systematic review was conducted by comprehensively searching electronic literature. The keywords, such as "Screw versus Cement Retained Fixed Implant Supported Reconstructions," "Screw Retained Fixed Implant." "Cement Implant" and "Dental Implant" were used for article searching. Twelve studies were included based on the determined inclusion and exclusion criteria. RESULTS: No significant difference was found between the screw-retained and cemented retained implant supported reconstructions. Dental implants are associated with complications leading to implant failure based on the type of restoration that is being used; cement-retained restoration and screw-retained restoration. The treatment selection must be based on the significance criteria and the tooth condition. CONCLUSION: Screw-retained implant-supported reconstructions were found to pose less biological and technological complications. Retention of the tooth is more stable and functional when implantation is selected based on the efficiency of a treatment procedure.

The effect of the addition of tricalcium phosphate to 5% sodium fluoride varnishes on the microhardness of enamel of primary teeth.

Aim. The aim of this study was to compare the effect of pH cycling on the microhardness of the enamel of primary human teeth treated with a conventional brown Sodium Fluoride (5% NaF) Varnish to those treated with a white Fluoride Varnish (5% NaF) enhanced with functionalized tricalcium phosphate (fTCP). Materials and Methods. Ninety extracted caries-free primary incisors were washed in a detergent and divided into three groups; group A received no treatment, teeth in group B were coated with Sodium Fluoride (5% NaF) Varnish, while teeth in group C were coated with 5% NaF varnish enhanced with functionalized tricalcium phosphate (fTCP). After ten days of pH cycling, the surface microhardness of the teeth was measured using a Knoop indenter. Results. The mean Knoop hardness number (KHN) of 5% NaF with fTCP was greater than that of 5% NaF alone while the control group had the lowest mean KHN. Conclusion. The results of this study suggest that the use of an additive such as fTCP to a fluoride varnish significantly improves the protective ability of the varnish on primary teeth in vitro.
