RESUMO

OBJECTIVES: To shed some light on a potential therapeutic modality that may facilitate resolution of botulism symptoms, namely 3,4-diaminopyridine (3,4-DAP). METHODS: In Riyadh, Saudi Arabia, we recently encountered a foodborne botulism outbreak that, luckily, was discovered early. In Prince Sultan Military Medical city, we admitted, during a period of approximately 3 weeks, 15 probable cases, 2 of which were excluded due to more likely alternative diagnoses. We report in this case series 13 highly suspected cases of botulism that we encountered during the outbreak. RESULTS: A total of 12 out of 13 patients required intensive care unit (ICU) admission, one of which required intubation. Symptoms included cranial nerve palsies, gastrointestinal symptoms, limb and respiratory muscle weakness. Patients showed clinical improvement when received botulinum antitoxin and 3,4-DAP if given early in the course of the disease. CONCLUSION: Early admisntration of 3,4-DAP may facilitate recovery and prevent disease progression. Larger prospective trials should be carried out to confirm that.

RESUMO

Calcinosis cutis is a quite unusual disease represented by abnormal accumulation of calcium salts in the skin and subcutaneous tissues. Repeated cutis calcinosis means recurrent calcium deposition in pre-existing areas. The case report illustrated the case of a 16-year-old female who had recurrent calcium deposits on the base of her right thumb. The patient initially had swelling at the base of her right thumb, which had been present for six months now. The patient described the dorsal solid mass on top of the thumb base, which was painful and had reduced thumb mobility. There was swelling that became painful, specifically located at the same site as the previous surgery, with thumb restriction and superadded infection at the metacarpophalangeal joint. Routine lab tests, including blood tests and rheumatologic and autoimmune work-ups, were normal. Plain radiographs and ultrasound examinations unveiled the characteristics of calcifications in the thumb tissues. A skin biopsy was done and the calcium deposits in subcutaneous tissue were confirmed, matching calcinosis cutis. The approach to the treatment of this condition entailed conservative measures. Some included physiotherapy to correct a flexion deformity, antibiotics, painkillers, and daily dressing. The patient was advised to follow up and to consider excision of the nodules. This case points out the clinical manifestations, investigations, and initial management of available strategies for recurrent calcinosis cutis. Further studies and long-term follow-up are necessary to determine the optimal treatment approaches and outcomes for this rare condition.

RESUMO

Disease transmission is dependent on a variety of factors, including the characteristics of an event, such as crowding and shared accommodations, the potential of participants having prolonged exposure and close contact with infectious individuals, the type of activities, and the characteristics of the participants, such as their age and immunity to infectious agents [1-3]. Effective control of outbreaks of infectious diseases requires rapid diagnosis and intervention in high-risk settings. As a result, syndromic and event-based surveillance may be used to enhance the responsiveness of the surveillance system [1]. In public health, surveillance is collecting, analyzing, and interpreting data across time to inform decision-making and aid policy implementation [1]. In this review article we aimed to provide an overview of the principles, types, uses, advantages, and limitations of surveillance systems and to highlight the importance of early warning systems in response to the information received by disease surveillance. The study conducted a comprehensive literature search using several databases, selecting, and reviewing 78 articles that covered different types of surveillance systems, their applications, and their impact on controlling infectious diseases. The article also presents a case study from the Hajj gathering, which highlighted the development, evaluation, and impact of early warning systems on response to the information received by disease surveillance. The study concludes that ongoing disease surveillance should be accompanied by well-designed early warning and response systems, and continuous efforts should be invested in evaluating and validating these systems to minimize the risk of reporting delays and reducing the risk of outbreaks.

RESUMO

With the onset of the COVID-19 pandemic in early 2020, several countries suspended or restricted mass gathering (MG) events to mitigate the risk of superspreading events. Prohibiting MGs aimed to lessen the likelihood of highly infectious persons coming into close contact with many others. Now that the world has opened its doors wide and removed most of precautionary measures, many questions arise. In this review, we aimed to summarize the current evidence regarding the policies and regulations that were implemented for the safe return of MG events. Besides, we highlighted the impact of the return of MG events during 2021 on the trajectory of COVID-19 spread. Canceling MG events can carry religious, societal, economic, and public negative consequences necessitating the safe return of these events. The experience with the COVID-19 pandemic was the foundation for the recommendations for the safe conduction of MG events during the pandemic by international public health bodies. When policymakers adequately applied precautionary measures and strategic approaches, we witnessed the safe holding of huge MG events without aggravating the COVID-19 situation or increasing the number of new cases beyond the capacity and readiness of the national healthcare system.

RESUMO

Background: The likelihood of survival of an out-of-hospital cardiac arrest quadruples with the rapid application of basic life support (BLS). The public's ability to perform cardiopulmonary resuscitation (CPR) and use automated external defibrillators (AEDs) is extremely important. This study aimed to assess the public knowledge, attitudes, and practices (KAP) of utilizing AEDs and to understand barriers to AED application. Methods: We conducted a cross-sectional study from March 1-30, 2022. An electronic questionnaire was constructed and validated to measure the KAP for public AED utilization and its barriers. Results: Of the 406 participants, 244 (60.10%) were males. Male respondents had 17% less knowledge and poorer attitude towards using an AED as compared to female respondents. Knowledge and attitudes on using AEDs were low (70.7%) among Saudi nationals compared to those of foreign nationals. Those who were BLS/CPR trained had a 2.5 times greater understanding and willingness to use AEDs in public than those who were not. Barriers to AEDs in CPR/BLS-trained participants were: (1) accidentally hurting the victim (14.3%), (2) duty as a bystander to just call the ambulance and wait for help (12.1%), (3) never taught what to do (n = 41, 18.4%), (4) did not want to be scolded if performed wrong (3.1%), and (5) never witnessed such a situation (51.6%). Conclusion: There is a strong association between knowledge of and willingness to use AEDs in emergency situations among the public. Misconceptions about AEDs hinder their use. This calls for urgent training programs through accessible technology to reach the public.

RESUMO

OBJECTIVES: Chemical, biological, radiological, and nuclear (CBRN) incidents are those that involve chemical or biological warfare agents or toxic radiological or nuclear materials. These agents can cause disasters intentionally or accidentally. Hospitals play a crucial role in handling CBRN disasters. This study aimed to assess the CBRN preparedness of government hospitals in Riyadh. METHODS: A descriptive cross-sectional study was conducted across government hospitals in Riyadh. All government hospitals with more than 100 inpatient beds and an emergency department met the inclusion criteria. Hospital preparedness was assessed using an adaptation of the CBRNE (chemical, biological, radiological, nuclear, or explosive event) Plan Checklist. This adaptation was chosen due to the inclusion of explosive events in hospital disaster readiness, and its structural composition of key clinical guidelines necessary for a comprehensive disaster and readiness plan. Results were described in frequencies across several domains such as foundational considerations and planning which are used to assess plan preparedness using readiness tools, training, and awareness among staff members in accordance to a pre-established emergency plan, placed procedures and their implementation, and modules for preparing for a biological incident, a chemical incident, and a radiological or nuclear incident. RESULTS: Of the 11 eligible hospitals, 10 participated in the study. Furthermore, CBRN considerations were included in the disaster plans of 7 hospitals. Drills had been conducted in collaboration with local agencies in only 2 hospitals. The staff had been trained to recognize the signs and symptoms of exposure to class (A) biological agents in less than half of the hospitals. Eight of the hospitals had antidotes and prophylactics to manage chemical incidents, but only half of them had radiation detection instruments. Personal protective equipment was available in all hospitals, but rapid access to stockpiles of medications was available in only half of them. CONCLUSIONS: Government hospitals in Riyadh demonstrated insufficient CBRN preparedness as per the CBRNE Plan Checklist. Overall, there was a lack of preemptive planning, application of pre-established policies and procedures, and adequate staff training. Furthermore, several hospitals had insufficient stockpiles of medications and in concrete plans on accessing government stockpiles in the case of an emergency. Therefore, their staffs should be trained to manage CBRN emergencies, and local drills should be conducted to improve their preparedness.

RESUMO

Background: Pilocytic Astrocytoma (PA) is the most common pediatric brain tumors. PAs are slow-growing tumors with high survival rates. However, a distinct subgroup of tumors defined as pilomyxoid astrocytoma (PMA) presents unique histological characteristics and have more aggressive clinical course. The studies on genetics of PMA are scarce. Methods: In this study, we report one of the largest cohort of pediatric patients with pilomyxoid (PMA) and pilocytic astrocytomas (PA) in Saudi population providing a comprehensive clinical picture, retrospective analysis with long-term follow-up, genome-wide copy number changes, and clinical outcome of these pediatric tumors. We examined and compared genome-wide copy number aberrations (CNAs) and the clinical outcome of the patients with PA and PMA. Results: The median progression free survival for the whole cohort was 156 months and it was 111 months for the PMA, however, not statistically significantly different between the groups (log-rank test, P = 0.726). We have identified 41 CNAs (34 gains and 7 losses) in all tested patients. Our study yielded the previously reported KIAA1549-BRAF Fusion gene in over 88% of the tested patients (89% and 80% in PMA and PA, respectively). Besides the fusion gene, twelve patients had additional genomic CNAs. Furthermore, pathway and gene network analyses of genes in the fusion region revealed alterations in retinoic acid mediated apoptosis and MAPK signaling pathways and key hub genes that may potentially be involved in tumor growth and progression, including BRAF, LUC7L2, MKRN1, RICTOR, TP53, HIPK2, HNF4A, POU5F, and SOX4. Conclusion: Our study is the first report of a large cohort of patients with PMA and PA in the Saudi population that provides detailed clinical features, genomic copy number changes, and outcome of these pediatric tumors and may help better diagnosis and characterization of PMA.

RESUMO

The viral RNA of SARS-Coronavirus-2 is known to be contaminating municipal wastewater. We aimed to assess if COVID-19 disease is spreading through wastewater. We studied the amount of viral RNA in raw sewage and the efficiency of the sewage treatment to remove the virus. Sewage water was collected before and after the activated sludge process three times during summer 2020 from three different sewage treatment plants. The sewage treatment was efficient in removing SARS-CoV-2 viral RNA. Each sewage treatment plant gathered wastewater from one hospital, of which COVID-19 admissions were used to describe the level of disease occurrence in the area. The presence of SARS-CoV-2 viral RNA-specific target genes (N1, N2, and E) was confirmed using RT-qPCR analysis. However, hospital admission did not correlate significantly with viral RNA. Moreover, viral RNA loads were relatively low, suggesting that sewage might preserve viral RNA in a hot climate only for a short time.

RESUMO

INTRODUCTION: Foreign body inhalation (FBI) is a serious and common emergency in children. Such children present in the emergency room (ER) with cough, shortness of breath, choking, or wheezing but rarely present with pneumomediastinum. PATIENT CONCERNS: Three children aged 2 to 5 years (2 girls and 1 boy) were seen in our ER complaining of FBI. Emergency bronchoscopy removal of the inhaled foreign body was performed; however, all 3 patients developed pneumomediastinum. DIAGNOSIS: A foreign body inhalation complicated by Pneumomediastinum/pneumothorax. INTERVENTION AND OUTCOMES: All the patients underwent emergency bronchoscopy and foreign body removal. After the ER intervention, 2 children were placed in the pediatric intensive care unit, and the pneumomediastinum resolved without intervention. The third patient required an operation for chest tube placement, which was then observed in the pediatric intensive care unit, and had several chest radiography follow-ups. After 5 days, the patient exhibited clinical improvement, and the chest tube was removed. CONCLUSION: In this case series, we present 3 cases of children aged 2 to 5 years seen in our ER with a history of different types of organic FBI complicated by pneumomediastinum/pneumothorax. Pneumomediastinum/pneumothorax is a rare complication of FBI in pediatric patients. However, such complications require multidisciplinary collaboration for early diagnosis and intervention.

RESUMO

PURPOSE: After the impressive results of the 2020 Hajj management, Saudi authorities decided to expand the quota to 60,000 pilgrims in 2021, which resulted in a convenient and successful experience. PATIENTS AND METHODS: This was a retrospective pre and post-study study conducted on all pilgrims attending the 2021 Hajj using the polymerase chain reaction (PCR) test surveillance with paired-swab samples (pre-Hajj and post-Hajj) to evaluate the risk potential of COVID-19 among Hajj pilgrims, the effectiveness of preventive measures and the potential effect of the Hajj ritual as a huge mass gathering on the epidemiological situation of the Saudi Arabian population. RESULT: Forty-one cases had positive COVID-19 infections out of a total of 58,428 pilgrims who attended the 2021 Hajj season, as detected by nonmandatory pre- and post-Hajj PCR. Notably, the 2021 Hajj season achieved a decreasing leg of the COVID-19 pandemic curve. The adjusted incidence rate in KSA from July 11th to August 7th ranged from 19 to 24 cases per 100,000 population. In contrast, the incidence rate for the same duration in Hajj ranged from 3 to 7 cases per 100,000 pilgrims. CONCLUSION: The Saudi mitigation plan ensured the safety of pilgrims and healthcare workers for Hajj, successfully limited the risk of COVID-19 transmission inside and contributed to global health security. The success story of Hajj in 2020 and 2021 during the pandemic represents a successful model for planning, achieving and managing future mass gatherings by integrating technology with global and national health policies and public health measures.

RESUMO

We aimed to prospectively evaluate and compare the effectiveness of Alvogyl and Cutanplast as intra-alveolar dressings for managing pain associated with extraction and incidence of dry socket. All patients who underwent maxillary and mandibular teeth extraction and fulfilled our inclusion and exclusion criteria from Feb 2021 to Oct 2021 were included in our study. Patients who were diagnosed with postoperative pain after tooth extraction were randomly allocated to three groups: Group A (Alvogyl), Group B (Cutanplast), and Group C (placebo). Pain relief and healing of the socket were compared between these groups. The collected data were analyzed using the Chi-square test and Z test of proportionality. Alvogyl was superior to the other medication for providing initial pain relief, and the incidence of dry socket was significantly lower than in the Cutanplast and placebo groups (p<0.05). However, wound healing was statistically non-significant among groups A, B, and C (p>0.05). Alvogyl is still the material of choice in terms of pain relief, wound healing, and low incidence of dry socket. Furthermore, no statistically significant difference was detected between the groups in the biographic information, location, and condition of the extracted tooth, presence of a radiologic pathology, or type of extraction procedure. Moreover, whether it is the first extraction or not, Alvogyl and Cutanpast are comparable in postoperative pain management as intra-alveolar dressing materials.

RESUMO

Introduction: To mitigate morbidity, mortality, and impacts of heat-related illnesses (HRIs) on health, it was vital to implement a comprehensive framework for HRI prevention and control. A recognized tool from the field of trauma prevention known as the Haddon matrix was applied. The matrix states that any event is affected by three factors: host, agent, and environment. In addition, another recognized tool known as the combined model was used in this study. The combined model is a three-dimensional model that includes the idea for the three axes of Haddon's matrix with the methodology of the community risk reduction (CRR) model. Aim of the study: To identify the environmental and individual risk factors of HRIs based on the Haddon matrix and the recommended prevention strategies by the CRR tool by using the combined model. Methodology: An extensive literature review was conducted to assess all the risk factors associated with HRI, as well as preventive measures. Then the Haddon matrix was used to structure, separating human factors from technical and environmental details and timing. After that, the combined model was used to set all responses and mitigation measures for each element obtained from the Haddon matrix tool. Conclusion: Projected increases in heat stress over the globe require the formulation and implementation of evidence-based HRI mitigation and preventive measures. In this study, we implemented the combined model that was utilized as a systematic strategy for the more theoretical framework of Haddon's matrix. Using the Haddon matrix to determine the HRI risk factors and the combined model to mitigate its impact was practical and helpful in planning, preparedness, and mitigating the HRIs during Hajj, provided a broad approach equivalent to the Swiss cheese model, and would facilitate an informed decision.

RESUMO

Background: Data on SARS-CoV-2 in infants ≤ 90 days are limited with conflicting reports regarding its presentation and outcomes. Methods: We conducted an ambispective cohort study using prospectively collected Health Electronic Surveillance Network Database by the Ministry of Health, Saudi Arabia. Infants of ≤ 90 days of age who had a positive RT-PCR test for SARS-CoV-2 virus were included. Patients were divided in Early neonatal (0-6 days), late neonatal (7-27 days), and post- neonatal (28-90 days) groups and were compared for clinical characteristics and outcomes by contacting parents and collecting information retrospectively. Results: Of 1,793 infants, 898 infants were included for analysis. Most infants in the early neonatal group had no features of infection (tested based on maternal positivity), whereas most infants in the late and post- neonatal groups were tested because of clinical features of infection. Fever and respiratory signs were the most common presenting feature in the late and post-neonatal groups. Hospitalization was higher in the early neonatal group (80%), compared to the two other groups. The overall mortality in the cohort was 1.6%. Conclusion: SARS-CoV-2 infection in infants ≤ 90 days might not be as rare as previously reported. The clinical presentation varies based on age at positive RT-PCR result.

RESUMO

BACKGROUND: Many survivors of COVID-19 have developed symptoms and diseases similar to those observed after severe acute respiratory syndrome (SARS). Therefore, this study aimed to characterize the symptoms that appear after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been eradicated and to determine their relationship with COVID-19 severity. METHODS: This multicenter, retrospective cross-sectional study was conducted in all eligible confirmed cases of SARS-CoV-2 infection from Saudi Arabia. Study participants were randomly selected using computerized random sampling from a population of 314,821 patients. Descriptive statistics were used to describe baseline demographic data and clinical characteristics. Categorical variables were presented as counts and percentages, while continuous variables were presented as means and standard deviations. RESULTS: Approximately 70% of patients were found to have five or fewer symptoms simultaneously. Late symptoms (in the ongoing symptomatic COVID-19) occurred in 225 (22·5%) patients with the most common late symptoms being loss of smell, loss of taste, fatigue, shortness of breath, and cough (52·4%, 31·1%, 11·5%, 10·2%, and 8·9% of patients with late symptoms, respectively). We also found that the presence of acute symptoms of COVID-19 and admission to the hospital were significant independent predictors of the post-COVID-19 condition. CONCLUSION: Saudi patients with COVID-19 develop a wide range of symptoms, similar to those observed and reported in other countries. The loss of smell, the loss of taste, shortness of breath, and fatigue were the main persistent symptoms. Regular follow-up of COVID-19 survivors is highly recommended to minimize the burden of the post-acute COVID-19 condition and improve the quality of life of patients.

RESUMO

INTRODUCTION: To mitigate morbidity, mortality, and impacts of COVID-19 on health, it was essential to implement a comprehensive framework for COVID-19 control and prevention. A well-recognized tool from the field of injury prevention known as the Haddon matrix was utilized. The matrix states that any accident is affected by the host, agent, and environment. Another well-recognized tool used by the national fire protection association known as the Community risk reduction tool (CRR). The (CRR) tool utilizes the Five E's of Community Risk Reduction. AIM OF THE STUDY: To describe the risk factors that increase the susceptibility and the severity of COVID-19 infection based on the Haddon matrix and the proposed prevention strategies by the CRR tool by using the combined model. METHODOLOGY: We reviewed the literature to assess known factors contributing to COVID-19 susceptibility, infection, and severity of infection. We then used the Haddon matrix to structure, separating human factors from technical and environmental details and timing. We then used the community risk reduction (CRR) model to set all responses and control measures for each element obtained from the Haddon matrix tool. Subsequently, we incorporated both tools to develop the combined model. CONCLUSION: we proposed and implemented a combined model that utilizes the CRR model as the systematic strategy for the more theoretical framework of Haddon's matrix. Combining both models was practical and helpful in planning the preparedness and control of the COVID-19 pandemic in Saudi Arabia that can be generalized to national and international levels.

RESUMO

BACKGROUND: With the spread of coronavirus disease 2019 (COVID-19), most countries rushed to take early measures to control this disease. AIMS: This paper describes and evaluates the Saudi Arabian strategic preparedness and response plan on COVID-19 up to 31 December 2020. METHODS: Saudi Arabia adopted the World Health Organization's guidelines on response to COVID-19, which are based on nine pillars of public health preparedness and response. The measures Saudi Arabia took are assessed against these pillars. RESULTS: In response to COVID-19, Saudi Arabia prepared public and private institutions to deal with the pandemic. Saudi authorities established a governance system comprised of responsible committees to continuously monitor national and international updates, trace contacts, screen the population, raise awareness and take proper actions to contain the spread of this disease. After the announcement of the first case in Saudi Arabia, all schools, social events, sports activities, domestic travel and international flights were suspended. Restrictions on social movement, social and religious gatherings, travel and businesses were imposed ahead of the first 100 confirmed COVID-19 cases. The Hajj pilgrimage for 2020 was scaled down to limit participants and no cases of COVID-19 were detected among pilgrims. The country maintained all basic health services and immunization programmes and supported all proposals for COVID-19 drugs and vaccines. The country is working to develop its capacity to produce these products and achieve self-sufficiency. CONCLUSION: Saudi Arabia took extreme measures to respond to COVID-19 which contributed to limiting the spread and effect of the disease.

RESUMO

BACKGROUND: A growing number of experiments have suggested potential cross-reactive immunity between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and previous human coronaviruses. We conducted the present retrospective cohort study to investigate the relationship between previous Middle East respiratory syndrome-coronavirus (MERS-CoV) infection and the risk of SARS-CoV-2 infection as well as the relationship between previous MERS-CoV and COVID-19-related hospitalization and mortality. METHODS: Starting in March 2020, we prospectively followed two groups of individuals who tested negative for COVID-19 infection. The first group had a previously confirmed MERS-CoV infection, which was compared to a control group of MERS-negative individuals. The studied cohort was then followed until November 2020 to track evidence of contracting COVID-19 infection. FINDINGS: A total of 82 (24%) MERS-positive and 260 (31%) MERS-negative individuals had COVID-19 infection. Patients in the MERS-positive group had a lower risk of COVID-19 infection than those in the MERS-negative group (Risk ratio [RR] 0.696, 95% confidence interval [CI] 0.522-0.929; p =0.014). The risk of COVID-19-related hospitalization in the MERS-positive group was significantly higher (RR 4.036, 95% CI 1.705-9.555; p =0.002). The case fatality rate (CFR) from COVID-19 was 4.9% in the MERS-positive group and 1.2% in the MERS-negative group (p =0.038). The MERS-positive group had a higher risk of death than the MERS-negative group (RR 6.222, 95% CI 1.342-28.839; p =0.019). However, the risk of mortality was similar between the two groups when death was adjusted for age (p =0.068) and age and sex (p =0.057). After controlling for all the independent variables, only healthcare worker occupation and >1 comorbidity were independent predictors of SARS-CoV-2 infection. INTERPRETATION: Individuals with previous MERS-CoV infection can exhibit a cross-reactive immune response to SARS-CoV-2 infection. Our study demonstrated that patients with MERS-CoV infection had higher risks of COVID-19-related hospitalization and death than MERS-negative individuals.

RESUMO

INTRODUCTION: The novel coronavirus (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a single-chain ribonucleic acid (RNA) virus. As of March 25, 2021, the total number of positive cases and fatalities in the Kingdom of Saudi Arabia (KSA) had reached 386,300 and 6624, respectively, with a case fatality rate of 1.71%. The KSA was among the leading nations to heed the advice of WHO officials and put strict precautionary and preventive measures in place to curb the early spread of COVID-19 before it was declared a global pandemic. METHODOLOGY: This was an uncontrolled before-after study following a mixed-method approach for data collection. National and regional data were extracted from the Health Electronic Surveillance Network (HESN), a centralized public health collection system for quantitative and statistical data. Quantitative and qualitative methods have been utilized in studying data derived from tech media. RESULTS: The Saudi authorities utilized different technological tools to aid in managing and combating the COVID-19 pandemic. In the case of Al Madinah Al Mounawarah, after the implementation of several technologies, the most important being Tawakkalna, the number of active daily cases decreased by 61%. CONCLUSION: The use of the Tawakkalna application was proven to be a successful method in fighting the COVID-19 pandemic in the KSA. This vital and essential experience warrants the use of different digital technology that offers a personalized profile displaying the person's status (affected, vaccinated, or no history of infection). This application played and will continue to play a crucial and effective role in pandemic containment in Saudi Arabia.
