Blood alcohol concentrations above defined levels are detrimental to cognitive performance. Empirical and published evidence suggest that nitrogen narcosis is analogous to alcohol intoxication with both impairing prefrontal cortex function. Nitrogen narcosis is also known to have been a factor in fatal accidents.

Defining a Safe Corridor of Cervical Branch Preservation in Lateral Platysmaplasty Surgery During Facial Rejuvenation Surgery.

Background: During rhytidectomies, the cervical branch of the facial nerve (CBFN) can easily be encountered, and potentially injured, when releasing the cervical retaining ligaments in the lateral neck. This nerve has been shown to occasionally co-innervate the depressor anguli oris muscle, and damage to it can thus potentially compromise outcomes with a postoperative palsy.

Objectives: The authors sought to examine the lateral cervical anatomy specific to the CBFN to ascertain if the position of the nerve can be predicted, thereby enhancing safety of the platysmal flap separation and dissection from this lateral zone of adhesion.

Internet-based training of coronary artery patients: the Heart Cycle Trial.

Low adherence to cardiac rehabilitation (CR) might be improved by remote monitoring systems that can be used to motivate and supervise patients and tailor CR safely and effectively to their needs. The main objective of this study was to evaluate the feasibility of a smartphone-guided training system (GEX) and whether it could improve exercise capacity compared to CR delivered by conventional methods for patients with coronary artery disease (CAD). A prospective, randomized, international, multi-center study comparing CR delivered by conventional means (CG) or by remote monitoring (IG) using a new training steering/feedback tool (GEx System).

Commentary: Hyperbaric oxygen treatment for wounds - evidence and the Sword of Damocles.

Increased access to any treatment sensibly follows the clinical and cost benefit being established. For many treatments this requires multiple, high-quality clinical trials and supporting cost analysis. Cost analysis may be applied to a single treatment or used to compare two or more treatments.

Unplanned pregnancy and contraceptive use in Hull and East Yorkshire.

Objective: This study has two aims. The first is to assess the proportion of unplanned pregnancies among women attending antenatal clinics (ANCs) and those undergoing induced abortion (IA). The second is to assess both their previous contraceptive use and contraceptive intention, with particular focus on the use or consideration of any long-acting reversible contraceptives in Hull and East Riding in order to inform service redesign.

Management of severe spinal cord injury following hyperbaric exposure.

There is an increasing body of evidence that drainage of lumbar cerebrospinal fluid (CSF) improves functional neurological outcome after reperfusion injury to the spinal cord that occasionally follows aortic reconstructive surgery. This beneficial effect is considered owing to lowering of the CSF pressure thereby normalising spinal cord blood flow and reducing the 'secondary' cord injury caused by vascular congestion and cord swelling in the relatively confined spinal canal. Whilst lacking definitive proof, there are convincing randomised controlled trials (RCTs), cohort data and systematic reviews supporting this intervention.

Options on fibroid morcellation: a literature review.

In laparoscopy, specimens have to be removed from the abdominal cavity. If the trocar opening or the vaginal outlet is insufficient to pass the specimen, the specimen needs to be reduced. The power morcellator is an instrument with a fast rotating cylindrical knife which aims to divide the tissue into smaller pieces or fragments.

Cold injury to a diver's hand after a 90-min dive in 6 degrees C water.

We present here a case of non-freezing cold injury (NFCI) in a sport scuba diver. There are similarities between the presenting symptoms of NFCI and decompression sickness, e.g.
