To investigate the knowledge, perceptions, and attitude of young doctors and nurses at Kind Abdulaziz University Hospital (KAUH) Jeddah, KSA, regarding the effectiveness of telemedicine in dealing with the patients for either follow-up or continuous monitoring of chronic diseases.

This prospective cross-sectional study was carried out on the young doctors and nursing staff at KAUH. An online questionnaire addressing all the required fields, i.e., background essential demography, perceptions, acceptance, and knowledge regarding telemedicine's utility, was sent to the targeted population of health care workers. Completed responses were analyzed statistically as per study objectives.

The response rate in our study was 85%. A total of 335 participants responded to our questionnaire. One hundred seventy-one (51.1%) were doctors, whereas one hundred sixty-four (48.9%) were the nursing staff. Among doctors, 50 (29.4%) were recent graduates, whereas, in the nursing side, 77 (46.7%) were the senior nursing studee promotion of telemedicine as an established way of managing patients with special requirements in an effective way. The ongoing COVID-19 pandemic has highlighted the importance of telemedicine in emergencies to protect both patients and health care workers by reducing chronic patients' avoidable hospital visits.The use of dental stem cells (DSCs) has emerged as a promising new approach for therapeutic purposes to treat dental and non-dental diseases. Thus, the aim of this systematic review was to compile all current information on the role and clinical applications of DSCs in modern regenerative medical therapy. PubMed and Google Scholar electronic databases were used to search the literature for relevant studies after applying specific inclusion and exclusion criteria. The search included articles that were published from 2009 to 2019. Several keywords were combined for the search (1) "Clinical applications", (2) "Dental Stem Cell", and (3) "Medicine". Only the 17 studies that fulfilled both the inclusion and exclusion criteria were included in this systematic review. These studies investigated different aspects of DSCs, including cell types, clinical applications, and updates of their use in regenerative medicine. All 17 studies favored the use of different DSCS in regenerative medicine to treat diseases, such as bone defects, neural and skin injuries, Parkinson's disease, ischemia, and others. None of the studies were conducted on humans. This systematic review demonstrated the growing body of evidence supporting the role of DSCs in the field of modern generative medicine. The noninvasive methods of isolating these cells compared to those for isolating non-DSCs make them promising potential sources for the treatment of chronic and devastating diseases. However, more studies are needed to develop the proper guidelines for cases in which DSCs could be considered an accurate and reliable tool for modern regenerative medicine in clinical trials.We present a case of a 48-year-old man's unexpected death affected by a relapsed clivalchordoma. After partial excision surgery of the neoplasm, he manifested 5 days later, in conditions of well-being, a sudden lethal extracranial hemorrhage from nose and mouth. The autopsy examination and the subsequent histological investigations did not allow us to clarify the exact origin of the bleeding. Based on the negativity of the accurate examinations performed, the extent of the bleeding, and the findings highlighted by the means of the nuclear magnetic resonance (NMR) carried out a few days before death, we have considered reasonable to localize the source of hemorrhage in the intrapetrous tract of the left internal carotid artery. Since this is a unique event, never previously documented, we believe that our report may be of interest to the scientific community.Acute promyelocytic leukemia (APL) is characterized by reciprocal translocation t(15;17)(q22;q21) and has a favorable prognosis upon immediate recognition and treatment. However, rare cases of APL show a cryptic insertion of retinoic acid receptor alpha (RARA) gene into promyelocytic leukemia (PML) gene which is negative both by fluorescence in situ hybridization (FISH) and conventional cytogenetics (CC). Morphology, cytochemistry and flow cytometry play a key role in early identification of such cases. Polymerase chain reaction (PCR) remains the most efficient diagnostic modality for detection of cryptic APL and other variants. It is important to identify these cases as they show beneficial response to retinoids and favourable prognosis. We herein present a rare case of cryptic APL negative by FISH and conventional cytogenetics but positive for PML-RARA by PCR.Pediatric melanomas are uncommon and sometimes arise in the background of giant congenital melanocytic nevus (GCMN). A 1-year-old girl was born with GCMN affecting her left half of the face and smaller nodules affecting trunk, hands, and feet. She developed an ulcerated lesion on the left temporoparietal scalp. The lesion showed features of GCMN along with large nests of a tumor composed of round cells with a vesicular nucleus, prominent nucleolus, plentiful mitoses, and areas of necrosis. Immunostaining for desmin, LCA, CD 20, CD 34, CD 99, BCL-2, and FLI1 was negative. Tumor cells showed immunopositivity for S-100 and HMB-45 confirming the diagnosis of melanoma. https://www.selleckchem.com/products/ucl-tro-1938.html Immunostaining for BRAF V600E was negative; however, NRAS mutation was detected on next-generation sequencing. Unlike adult melanomas BRAF mutations are rare but NRAS mutations have been reported in pediatric melanomas. Adjunctive molecular testing will be important to understand the genetic basis of this disease and future targeted therapy.Malignant eccrine spiradenoma is an extremely rare neoplasm of adnexal origin. It almost always originates from a preexisting long standing eccrine spiradenoma. We present a case of malignant eccrine spiradenoma arising from benign counterpart and having both carcinomatous and sarcomatous differentiation. Here we present a case of a 46 years old lady who presented with a long standing small nodule on her left leg of 7 years' duration with suddenly increase in size. Grossly the mass was partly solid and partly cystic measuring 11.5 cm in maximum dimension with cystic area forming the deeper plane. On microscopy, the superficial dermis showed well demarcated lobules of benign eccrine spiradenoma. Deeper dermis showed tumor cells with features of malignant transformation having both carcinomatous and sarcomatous component. After wide local excision patient is now doing well. The diagnosis of malignant eccrine spiradenoma requires a thorough histopathological examination of the lesion and requires finding a focus of benign spiradenoma within or adjacent to malignant tumour.
