Ariadne's Thread: An Easy Way to Find Your Way Back to the Glenohumeral Joint Through the Posterior Portal Once You Have Left.

ABSTRACT: Finding the way back into the glenohumeral space after a time-consuming rotator cuff reconstruction is not always easy because of swelling of the surrounding soft tissues. We present a safe and quick technical tip on how to reintroduce the arthroscope by means of a transarticular suture. After primary work in the glenohumeral space is performed and before the arthroscope is withdrawn from the joint, a monofilament suture is channeled from the anterior working portal through the glenohumeral joint to exit from the posterior portal. Once the subacromial reconstruction of the posterosuperior cuff tear is finished and the surgeon wants to re-establish the posterior portal to the glenohumeral space to assess the reconstruction intra-articularly, the channeled suture limb can be used to re-enter the posterior portal and to find the way back into the glenohumeral joint without harming the reconstruction. This fast and easy tip might be helpful for any arthroscopic shoulder surgeon who wants to reassess the glenohumeral space at the end of a procedure on a regular basis without losing time or his or her nerve and who wants to prevent additional damage to the posterior soft tissues.

Project description:BackgroundMass strandings of sperm whales (Physeter macrocephalus) remain peculiar and rather unexplained events, which rarely occur in the Mediterranean Sea. Solar cycles and related changes in the geomagnetic field, variations in water temperature and weather conditions, coast geographical features and human activities have been proposed as possible causes. In December 2009, a pod of seven male sperm whales stranded along the Adriatic coast of Southern Italy. This is the sixth instance from 1555 in this basin.Methodology/principal findingsComplete necropsies were performed on three whales whose bodies were in good condition, carrying out on sampled tissues histopathology, virology, bacteriology, parasitology, and screening of veins looking for gas emboli. Furthermore, samples for age determination, genetic studies, gastric content evaluation, stable isotopes and toxicology were taken from all the seven specimens. The animals were part of the same group and determined by genetic and photo-identification to be part of the Mediterranean population. Causes of death did not include biological agents, or the "gas and fat embolic syndrome", associated with direct sonar exposure. Environmental pollutant tissue concentrations were relatively high, in particular organochlorinated xenobiotics. Gastric content and morphologic tissue examinations showed a prolonged starvation, which likely caused, at its turn, the mobilization of lipophilic contaminants from the adipose tissue. Chemical compounds subsequently entered the blood circulation and may have impaired immune and nervous functions.Conclusions/significanceA multi-factorial cause underlying this sperm whales' mass stranding is proposed herein based upon the results of postmortem investigations as well as of the detailed analyses of the geographical and historical background. The seven sperm whales took the same "wrong way" into the Adriatic Sea, a potentially dangerous trap for Mediterranean sperm whales. Seismic surveys should be also regarded as potential co-factors, even if no evidence of direct impact has been detected.
