Comparison of surgical outcomes using Gyrus PKS™ vs LigaSure™ in total laparoscopic hysterectomy: A randomised controlled trial.

Background: Advanced vessel sealing devices are widely used in laparoscopic surgery. However, there remains a lack of adequately powered trials comparing laparoscopic advanced vessel sealing devices in the clinical setting, especially in gynaecology.

Aims: This single-blinded randomised controlled trial aims to compare the surgical outcomes of total laparoscopic hysterectomy (TLH) using either the Gyrus PKS™ LYONS dissecting forceps or the LigaSure™ Maryland jaw vessel sealer/divider.

Medical management of miscarriage: Predictive factors of success.

Medical management of miscarriage is an acceptable option available to women, and has advantages of providing timely treatment, while avoiding exposure to surgery and anaesthesia. This retrospective cohort study aimed to determine factors predictive of successful medical management, utilising a single dose protocol of 800 µg vaginal misoprostol. In this cohort, the success rate was 67% (199/296), and smaller mean gestational sac diameter independent of gestational age predicted success (P = 0.

Carbon dioxide and methane measurements from the Los Angeles Megacity Carbon Project - Part 1: calibration, urban enhancements, and uncertainty estimates.

We report continuous surface observations of carbon dioxide (CO) and methane (CH) from the Los Angeles (LA) Megacity Carbon Project during 2015. We devised a calibration strategy, methods for selection of background air masses, calculation of urban enhancements, and a detailed algorithm for estimating uncertainties in urban-scale CO and CH measurements. These methods are essential for understanding carbon fluxes from the LA megacity and other complex urban environments globally.

Inferior epigastric artery: Surface anatomy, prevention and management of injury.

The anatomical position of the inferior epigastric artery (IEA) subjects it to risk of injury during abdominal procedures that are close to the artery, such as laparoscopic trocar insertion, insertion of intra-abdominal drains, Tenckhoff(®) catheter (peritoneal dialysis catheter) and paracentesis. This article aims to raise the awareness of the anatomical variations of the course of the IEA in relation to abdominal landmarks in order to define a safer zone for laparoscopic ancillary trocar placement. Methods of managing the IEA injury as well as techniques to minimise the risk of injury to the IEA are reviewed and discussed.

Red blood cell phenotype matching for various ethnic groups.

Patients requiring chronic transfusion support are at risk of alloimmunization after red blood cell (RBC) transfusion because of a disparity between donor and recipient antigen profiles. This research explored the probability of obtaining an exact extended phenotype match between blood donors randomly selected from our institution and patients randomly selected from particular ethnic groups. Blood samples from 1,000 blood donors tested by molecular method were evaluated for the predicted phenotype distribution of Rh, Kell, Kidd, Duffy, and MNS.
