Risperidone-Induced Acute Laryngeal Dystonia: A Case Report.

BACKGROUND Antipsychotic medications are associated with multiple adverse effects, including metabolic syndrome, prolonged QT interval, and extrapyramidal symptoms. Acute laryngeal dystonia (ALD) is a rare and lethal form of extrapyramidal reaction. CASE REPORT A 27-year-old woman with schizophrenia on risperidone presented to our Emergency Department with a sensation of choking and respiratory distress, mimicking a panic attack.

Seventy-two-hour emergency department revisits among adults with chronic diseases: a Saudi Arabian study.

Background: Despite the increase in adult emergency department (ED) utilization in Saudi Arabia, no studies have evaluated the 72-hour revisits. This study estimates the rate of 72-hour ED revisits and identifies its reasons and predictive factors among adults with chronic diseases.

Patients And Methods: A hospital-based retrospective study that included 24,206 ED discharges for adults with chronic diseases at the adult ED of King Abdulaziz Medical City, Riyadh between September 13, 2015 and July 29, 2017 was performed.

Emergency department 72-hour revisits among children with chronic diseases: a Saudi Arabian study.

Background: Emergency Department (ED) revisits have often been used as an indicator of medical care quality. This study aimed to quantify the frequency of ED revisits within 72 h of discharge and identify its factors among children with chronic diseases.

Methods: We designed a retrospective cohort study of children with at least one chronic disease who were also under 18 years of age and had attended and were discharged from the ED at King Abdullah Specialist Children's Hospital (KASCH-RD), Riyadh, Saudi Arabia between April 19, 2015 and July 29, 2017.

Development of a risk-prediction model for Middle East respiratory syndrome coronavirus infection in dialysis patients.

Introduction The Middle East respiratory syndrome coronavirus (MERS-CoV) infection can cause transmission clusters and high mortality in hemodialysis facilities. We attempted to develop a risk-prediction model to assess the early risk of MERS-CoV infection in dialysis patients. Methods This two-center retrospective cohort study included 104 dialysis patients who were suspected of MERS-CoV infection and diagnosed with rRT-PCR between September 2012 and June 2016 at King Fahd General Hospital in Jeddah and King Abdulaziz Medical City in Riyadh.

Early identification of pneumonia patients at increased risk of Middle East respiratory syndrome coronavirus infection in Saudi Arabia.

Background: The rapid and accurate identification of individuals who are at high risk of Middle East respiratory syndrome coronavirus (MERS-CoV) infection remains a major challenge for the medical and scientific communities. The aim of this study was to develop and validate a risk prediction model for the screening of suspected cases of MERS-CoV infection in patients who have developed pneumonia.

Methods: A two-center, retrospective case-control study was performed.

Stress and its predictors in pregnant women: a study in Saudi Arabia.

Background: Although stress during pregnancy has negative effects on children's development and pregnant women's health, no study has assessed stress and its predictors among pregnant Saudi women. The aim of this study was to assess stress and identify its predictors in a sample of pregnant Saudi women.

Methods: A correlational study was carried out at King Abdulaziz Medical City in Riyadh, Kingdom of Saudi Arabia, on 438 pregnant women who attended the obstetrics/gynecology clinic.

Systematic review and meta-analysis for the use of ultrasound versus radiology in diagnosing of pneumonia.

Background: Physicians are increasingly using point of care lung ultrasound (LUS) for diagnosing pneumonia, especially in critical situations as it represents relatively easy and immediately available tool. They also used it in many associated pathological conditions such as consolidation, pleural effusion, and interstitial syndrome with some reports of more accuracy than chest X-ray. This systematic review and meta-analysis are aimed to estimate the pooled diagnostic accuracy of ultrasound for the diagnosis of pneumonia versus the standard chest radiological imaging.

Nail embolization to the femoral artery.

Modern air-nailing tools are known to cause penetrating trauma. We report the unusual case of a pneumatically fired carpenter's nail that penetrated the chest of a 30-year-old man and subsequently embolized from the heart to the left femoral artery without clinical evidence of having entered the heart. The nail was surgically removed, and the patient was discharged from hospital without sequelae after 10 days.

Initial emergency department trauma scores from the OPALS study: the case for the motor score in blunt trauma.

Objectives: To compare the predictive accuracy of the Revised Trauma Score (RTS), the Glasgow Coma Scale (GCS), and their components in blunt trauma patients.

Methods: This multicenter prospective cohort study was conducted in 20 communities as part of the Ontario Prehospital Advanced Life Support (OPALS) Study. It included adult trauma patients with Injury Severity Scores >12.
