Article Synopsis
  • - The study examines dermatological conditions presented in the emergency department (ED) over a period from January 2021 to May 2023, using a chart review of 301 cases.
  • - Findings reveal that most patients were children with a balanced gender distribution, primarily presenting during winter, with low triage levels, indicating less severe cases, and a median visit duration of over 5 hours.
  • - Viral infections were the most common complaints, with maculopapular rashes being the leading finding; the study suggests that many cases could be effectively managed by primary care physicians instead of requiring ED visits.

Stress, a state of mental or emotional strain or tension brought on by challenging or demanding events might hamper a dentist's ability to react quickly and prudently. Their ability to deal with difficult patients may also be compromised, especially when dealing with frightened or anxious people. The main goal of this study was to survey a wide range of dental professionals from different backgrounds, including undergraduates, general practitioners and specialists, and determine how much stress each group was experiencing and how it affected both the participants and the treated patients.

  • The study aimed to assess the usefulness of DQ-genotyping in screening for celiac disease (CD) among type 1 diabetic (T1D) patients in a Saudi population, focusing on the frequency of DQ-genotypes, associated risks, and cost-effective screening strategies.
  • Involved 67 T1D patients with CD and 224 without, analyzing their HLA-DQ genotypes to compare risks of developing CD.
  • Results showed a significant correlation between homozygous DQ2.5/DR3-DQ2.5 genotypes and increased risk for CD, while only 4% of patients had no risk genotypes, confirming celiac serology tests

Spontaneous stress fracture of the scapular spine associated with rotator cuff tendinopathy is a rare complication in an elderly patient. Rotator cuff tendinopathy is a common condition characterized by degeneration and inflammation of the rotator cuff tendons. On the other hand, stress fractures are small cracks or breaks in bones that occur in response to repetitive or excessive mechanical loading.

This research focuses on examining the potential impact of charcoal briquettes and lumps on human health due to the emissions they release, and verifying their quality standards. Quality assessment was conducted using a device capable of measuring toxic gases to identify contaminants from various sources such as biomass, synthetic resins, coal, metals, and mineral matter. Toxicity assessments were carried out on five types of briquettes and two varieties of lump charcoal.

The development of ceramic brackets in orthodontics three decades ago emerged as a response to the increasing patient demand for less visible orthodontic appliances. While these brackets provide superior aesthetics, they are characterized by lower fracture toughness and higher bond strength in contrast to metal brackets. These properties present challenges during the debonding step, including the risk of enamel micro-fractures and cracks.

Renomedullary interstitial cell tumors (RMICTs) are rare benign renal tumors that arise from the renal medulla. They are rarely symptomatic and are mostly discovered incidentally. Radiologically, their co-presence ipsilaterally in the background of a larger mass introduces a miscellaneous presentation that raises the suspicion of metastatic disease.

Introduction: Testicular torsion (TT) is a rare but urgent condition; it leads to severe pain and swelling that must be diagnosed and treated immediately, where there is an expectant period of 6-8 h. It is an important prognostic factor in the arrival time to the emergency department. Raising awareness about TT is essential to ensure early diagnosis and timely treatment, which can prevent irreversible damage and loss of fertility.
