Background Children often suffer from congenital or acquired diseases. Ambulatory cases represent the vast majority of pediatric surgical cases. COVID-19 pandemic-associated regulatory precautions had made the process of seeking medical advice at a suitable appointment such a big problem. We utilized telemedicine (online encounter) to deliver the required healthcare service for sorting and guiding pediatric ambulatory surgical patients. In this article, we aimed to: (1) present our experience, (2) evaluate the effectiveness, and (3) document the results of this technology to solve the problem of difficult healthcare accessibility. Materials and Methods In this study, we compared the utilization of telemedicine (virtual clinic via video consultation) prospectively in the current era of the COVID-19 pandemic in the period from June 2020 to July 2021 to the in-person clinic encounter at the outpatient department (OPD) retrospectively in the previous year (from June 2019 until the end of May 2020) for perioperative management of pediatric ambulatory surgical patients. The study was conducted at 3 tertiary care pediatric surgery centers. The information recorded for analysis included: demographic data, surgical condition distribution, time interval from the appointment request till the actual encounter with the surgeon, conversation duration, distance traveled, and ultimate fate of the consultations. For both groups, service was evaluated after the first follow-up visit by a patient survey questionnaire (Patient Experience Assessment form) including questions relevant to each encounter. Results A total of 1124 pediatric patients with various ambulatory surgical conditions had been scheduled for virtual clinic video encounters. Of them, 1056 cases were evaluated by video consultation, supervised by their parents or caregivers, thus, achieving an attendance rate of 94%. Of the remaining cases, 2% (n=23) were canceled and 4% (n=45) did not attend the virtual clinic. Two-thirds of the cases live in rural /remote areas. Patients’ overall satisfaction was 92%. This was in comparison to 872 pediatric ambulatory surgical patients scheduled for in-person clinic visits before the implementation of the virtual clinic. Of them, only 340 cases had attended the clinic, thus, achieving an attendance rate of 39%. Of the remaining cases, 450 cases (51.6%) were canceled and 82 cases (9.4%) did not attend the clinic (no show). About 48% of the cases live in rural areas. For this group, patients’ overall satisfaction was 63%. The mean encounter duration was similar for both groups (∼ 5 minutes). Surgical condition distribution was also similar (p-value: 0.694). For new cases, the time interval from appointment request till the actual encounter was very short for the virtual clinic group (range: 6-15 days) as compared to the in-person clinic group (range: 30-180 days). Patients were followed up for a median period of 14±3.25 months (range: 6-22 months) with no patient loss to follow-up. Conclusion Telemedicine can effectively bridge the patient-physician communication gap caused by the regulatory precautions mandated by the current COVID-19 pandemic. It achieved an attendance rate of 94% and parents’ / patients’ overall satisfaction of 92%.

To study the effect of intravenous injection of bone marrow mesenchymal stem cells (BMMSCs), alone and combined with NO inducer in gastric ulcer healing in a rat model.Rats were divided into controls, gastric ulcer, gastric ulcer receiving mesenchymal stem cells (MSCs), gastric ulcer receiving NO inducer (l-Arginine), gastric ulcer receiving MSCs plus NO inducer (l-Arginine) groups. MSCs were given in a dose of (10Injection of MSCs or NO inducer or both to the gastric ulcer group significantly decreased caspase-3 and BAX genes expression (apoptotic factors) and increased Bcl-2 gene expression (anti-apoptotic factor) compared to that of the gastric ulcer group after both 24h and 7days with more significant results in the gastric group received both MSCs and NO inducer. HGF gene expression was significantly increased in the groups injected with MSCs or NO inducer or both compared with the corresponding gastric ulcer group (p0.05, p0.05p0.001 respectively). There was a significant decrease in the mean PGE2 and TNF-α levels in the gastric ulcer group receiving MSCs, the gastric ulcer group receiving NO and the gastric ulcer group receiving both MSCs andNO compared to the gastric ulcer group after both 24h and 7days. Histopathological examination of gastric tissue of groups that received stem cells or NO alone, showed mucosal regenerative changes with increased thickness together with reduced inflammatory cellular infiltrate in the submucosa and decreased congestion. There was complete restoration in gastric mucosa in the group that received both stem cells and NO.Administration of MSCs, NO, or MSCs plus NO may exert a therapeutic effect on the mucosal lesion in gastric ulcer through their anti-inflammatory, angiogenic and antiapoptotic actions.
