Purpose. Injecting triamcinolone acetonide (TA) into a keloid is physically challenging due to the density of keloids. The purpose was to investigate the effects of various syringe and needle combinations on the injection force to determine the most ergonomic combination. Materials and Methods. A load cell was used to generate and measure the injection force. Phase 1: the injection force of 5 common syringes was measured by injecting water into air. The syringe that required the lowest injection force was evaluated with various needle gauges (25, 27, and 30 G) and lengths (16, 25, and 38 mm) by injecting TA (40 mg/mL) into air...

Evidence suggests that there is variation in support for specific chicken farming practices amongst stakeholder groups, and this should be explored in more detail to understand the nature of these differences and work towards convergence. Online focus groups were used to assess attitudes to animal welfare in meat chicken farming in this pilot study. Across six online chats, 25 participants (general public, n = 8; animal advocacy group, n = 11, meat chicken industry, n = 3; research or veterinary practice who had experience with poultry but no declared industry affiliation, n = 3) discussed meat chicken intensification and welfare...

Despite being a common procedure, percutaneous renal biopsy (PRB) carries the potential for complications. The British Association of Paediatric Nephrologist (BAPN) has published standards for pediatric PRB. As Indian data are scarce, we conducted a prospective audit of 100 consecutive pediatric renal biopsies (60% males) under real-time ultrasound guidance. Nephrotic syndrome was the most common indication for PRB (68%) with minimal change disease (30%) and focal segmental glomerulosclerosis (25%) being the most common histopathological lesions...

BACKGROUND: The surgical case of a dropped intraocular lens inside the vitreous cavity constitutes a real challenge for the operating surgeon. Herein, we describe a case series where an alternative optical rehabilitation technique for late intraocular lens-bag complex dislocation has been used. METHODS: A modern vitrectomy device was used to remove the capsule with the dropped intraocular lens using sutureless 25-gauge pars plana vitrectomy. To ensure a better aesthetic result, with faster patient recovery and a reduced number of operations, the whole procedure was performed during the same operating session; an iris-claw intraocular lens for aphakia was selected for implantation...

BACKGROUND AND OBJECTIVES: Novel multitined cannulae constitute an attractive option for ultrasound-guided radiofrequency neurotomy of cervical medial branches. The deployment tines increase the cannula's active area, thus altering its lesion size. Despite their theoretical benefits, multitined cannulae have not been assessed. In this bench study, we sought to investigate the lesions produced by a standard 18-gauge and 2 commercially available multitined deployment cannulae. We created ex vivo models to evaluate lesion morphology at a periosteal interface using approach angles likely to be encountered during an ultrasound-guided technique...
