The carotid angiographic studies performed in a teaching hospital (King Khalid University Hospital, Riyadh) in Saudi Arabia were reviewed, and the incidence of lesions demonstrated was analysed. Intracranial tumours accounted for 50% of the lesions, with meningiomas being 40%, whilst arteriovenous malformations accounted for 5.9% of lesions. It was noted that the incidence of atherosclerosis and arteritis was low, and the examination was almost without complications. Some lesions supplied by vertebral arteries were missed. In view of this, vertebral angiography is advocated in those cases with suspected supratentorial tumour especially when the carotid angiograms are normal.

Omissions or delays in desmopressin can result in serious patient harm in patients with Arginine-Vasopressin Deficiency (AVP-D), formally known as Cranial Diabetes Insipidus (CDI). Desmopressin administration practice in hospitals has not been thoroughly investigated previously. This study evaluated desmopressin prescription and administration practice at a large tertiary centre.

Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

Virtual reality technology offers an extended and repeatable environment for delivering digital learning and training. This study investigated the acceptance of a smartphone virtual reality training program among nursing students for chemotherapy administration using a modified Technology Acceptance Model. The teaching materials for the chemotherapy administration process were designed using smartphone virtual reality to provide prelicensure students with an opportunity to learn procedural steps in a controlled, risk-free environment.
