Authors: Mungmunpuntipantip, Rujittika; Wiwanitkit, Viroj Abstract: A second booster dose of COVID-19 vaccine is a widely discussed issue globally. This letter to the editor describes on possible additional immunoprotection due to the fourth dose of COVID-19 vaccine. According to the modeling study, it can demonstrate that the fourth dosage of COVID-19 vaccination can still provide extra immunoprotection in case that previous doses are not the highly effective COVID-19 vaccines.

Abstract: In children, traumatic radial head dislocation (RHD) is usually associated with ulnar fracture or deformation as reported in a Monteggia injury or its Monteggia variant. Isolated traumatic RHD is extremely rare and exceptional. Traumatic RHD is frequently missed on initial radiographs, particularly if it is isolated. The management of missed RHD is challenging and remains controversial. We report a Case of chronic posttraumatic RHD in a three-year-old child treated with open reduction and reconstruction of the annular ligament. The child’s elbow was stable during the followup, without swelling or deformity, and the elbow function was normal. The injury of the reported case does not belong to any lesion described in the Monteggia-variant classification, which might explain the reason for missing the associated dislocation. The authors recommend urgent open reduction when a chronic RHD is diagnosed and annular ligament reconstruction, particularly when the open reduction is unstable.

A 15-year-old Para 0 þ0 secondary school student presented to the emergency department in shock with a 1-year history of painless vaginal protrusion, vaginal bleeding, foul-smelling vaginal discharge, occasional passage of blood clots, fatigue, fainting episodes, and weight loss. She was resuscitated with intravenous fluids and blood transfusions. General examination revealed a young girl with a 16- week sized abdominal mass. Vaginal examination revealed a large mobile fleshy mass 14 cm by 10 cm with an offensive discharge and odour. It was externally friable, bled actively on contact, had areas of tissue necrosis, and was oedematous. It was difficult to determine the adnexa structures because of tenderness. Examination under anaesthesia showed that the mass was continuous with the cervix and was not attached to the vagina or vulva. The histology report of the biopsied specimens showed features consistent with cervical leiomyosarcoma (LMS). Cervical LMS was confirmed by immunohistochemistry and a total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed as definitive treatment. Postoperative hormone replacement therapy was initiated. The patient’s postoperative condition was stable and there was no tumour recurrence for >2 years on follow-up. Making a diagnosis and instituting surgical and adjuvant treatments for LMS in a low-resource setting are challenging. This is due to lack of access to universal healthcare coverage. A multidisciplinary approach with early diagnosis and complete surgical resection of the tumour provides the most favourable possibility of an improved survival and quality of life.

Abstract: Objectives: This study aimed to assess perceptions among undergraduate medical students toward distance learning and its effects on their academic performance during the COVID-19 pandemic at Al-Qunfudhah College of Medicine, Umm Al-Qura University, KSA. Material and Methods: A cross-sectional study was conducted among medical students at Al-Qunfudhah College of Medicine, Umm Al-Qura University, KSA, during the 2020e2021 academic year. Data were collected through a predesigned, well-structured online survey from (1st March to 31th May 2021). Results: A sample of 223 undergraduates responded to an online survey, with a response rate of 74.3%; female students represented 54.3%. Blended education was preferred by most students (73.1%). Moreover, 72.2% of students perceived that distance learning saved their time, and approximately two-thirds (61.4%) were stimulated by the availability of lecture recordings. Approximately 59% and 54% reported that distance learning was more comfortable and improved their technology skills, respectively. Poor communication (66%) and network problems (61.4%) were the most common challenges in distance learning. Nonetheless, a substantial increase (P ¼ 0.001) in students’ grade point averages was observed with distance learning. Conclusion: Most medical students preferred blended education combining the advantages of both traditional and distance learning strategies. The availability of educational materials, improvements in students’ technological skills and time saving were the most perceived benefits of distance learning among students. However, the main obstacles were internet problems, poor communication and deprivation from real clinical practice. Despite the improvement in students’ grade point averages during distance learning compared with traditional learning, blended education was recommended by the majority or participants.
