Study of the toxicity of the essential oil of Brocchia cinerea.

Brocchia cinerea is a North African plant belonging to the Asteraceae family, widely utilized in Algerian folk medicine to treat a variety of illnesses. These therapeutic virtues are mainly due to the plant essential oil. The chemical components of this oil were identified using GC-MS, and the variability in these components' levels was examined in nine samples that were taken at different times from two locations in Algeria's northern Sahara.

The role of dexmedetomidine as an adjuvant for high-thoracic erector spinae plane block for analgesia in shoulder arthroscopy; a randomized controlled study.

Background: Management of postoperative pain after shoulder arthroscopy is an important issue. Dexmedetomidine, as an adjuvant, improves nerve block efficacy and decreases postoperative consumption of opioids. As a result, we designed this study to determine if adding dexmedetomidine to an erector spinae plane block (ESPB) that is guided by ultrasound (US) is beneficial for treating immediate postoperative pain following shoulder arthroscopy.

Challenges During Review of COVID-19 Research Proposals: Experience of Faculty of Medicine, Ain Shams University Research Ethics Committee, Egypt.

The COVID-19 pandemic resulted in an overwhelming increase in research studies submitted to research ethics committees (RECs) presenting many ethical challenges. This article aims to report the challenges encountered during review of COVID-19 research and the experience of the Faculty of Medicine, Ain Shams University Research Ethics Committee (FMASU REC). From April 10, 2020, until October 13, 2020, the FMASU REC reviewed 98 COVID-19 research protocols.

Liver disease during and after hematopoietic stem cell transplantation in adults: a single-center Egyptian experience.

Background: Hepatic complications are a well-known cause of both early and late mortality and morbidity in hematopoietic stem cell transplant (HSCT) recipients. Early diagnosis and management of hepatic complications is important in order to commence appropriate therapy. Conditioning regimens, acute and chronic graft versus host disease, sinusoidal obstruction syndrome, and infections among others represent major hepatic complications for the transplant recipient.

In situ synthesis of FeO@ cyanoethyl cellulose composite as antimicrobial and semiconducting film.

Cyanoethyl cellulose (CEC)/ magnetite (FeO) flexible composite film with enhanced dielectric and magnetic properties was successfully prepared. CEC has been synthesized from micro crystalline cellulose (MCC). The effects of magnetite mass fraction on the morphology, microstructure, thermal stability, and antimicrobial activity of the as-prepared composite films were investigated.

Chemical composition, in vitro antioxidant and antibacterial activities of subsp. (dostál) greuter.

The current study focuses on the chemical composition, and evaluation of antioxidant and antibacterial activity of the aerial parts of subsp. . Using different chromatographic methods nine compounds 1-9 were isolated.

Acetabular dysplasia in adult hips of a Saudi population. A possible relation to coxarthrosis.

Objective: To evaluate acetabular morphology and the prevalence of dysplasia in a Saudi population, and compare it with others in different geographical areas.

Methods: The study took place at King Fahd University Hospital, Al-Khobar, Kingdom of Saudi Arabia from May 2005 to April 2006. We recruited radiographs of 104 patients of 40-88 years of age.

Can double gloves improve surgeon-patient barrier efficiency?

The aim of this study was to compare double gloves (DGs) with single gloves (SGs) during orthopedic and trauma surgery in prevention of blood contact between patients and surgeons. DGs and SGs were collected after orthopedic operations, tested for size, site, and number of perforations. Medical records were reviewed for age, sex, type of operation, duration, and postoperative wound infection.
