Pseudoxanthoma elasticum (PXE) is characterized by a progressive fragmentation and calcification of elastic fibers in connective tissue and when Bruch membrane (BM) is affected ocular modifications can be found. Recently, Optical coherence tomography-angiography (OCT-A) contribute to a better comprehension of lesions in PXE.

A growing body of evidence gathered over the past 10 years has demonstrated a clear escalation of sudden death (SD) in Chinese medical staff. This retrospective study was conceived to explore the first evidence of signs of SD, relieving clinical workload and strengthening protection against the overload of Chinese medical staff.

This article describes the procedure we followed in a small rural medical capacity in Greece, to improve a crucial aspect of the everyday clinical practice and adopt a culture of auto-regulation through the procedure of Audit. As Doctors of the Amfiklia Health Center we are often called to leave the office and deal with emergency cases out of the Health Center. It was common ground that the maintenance of the Emergency Bag we use in these cases is neglected. We audited our practice using certain standards, analyzed the findings, recommended regulations, implemented the changes and re-audited our practice. At the end of this project we managed to ensure that the Emergency Bag has almost all of the necessary drugs and consumables which will be in-date. We also managed to improve our practice with regards to the appropriate recording of the Controlled Drugs used during such cases.

Gaining weight outside of the Institute of Medicine guidelines puts a woman and her foetus at an increased risk. Limited or incorrect information is being provided to women during antenatal care. Research shows that physicians do not perceive this as an important issue. We aimed to assess both physician and patient perspective to weight gain in pregnancy as well as assessing physicians current practice to weight management. 71% of women want to be given a target weight to gain during pregnancy; 87% want to be told if they are gaining an inappropriate amount of weight. 87.5% of physicians believe that weight management is important; 31.2% advise patients about weight gain.

Research on the stem cell biology of the minipig is rapidly developing. Although research on mouse and human stem cells currently predominates over that in other species, data from these species have provided a good foundation for current and future porcine stem cell research. In addition, the increasing popularity of alternate-species models in the study of human diseases and disease mechanisms has spurred porcine stem cell research. As a source of pluripotent embryonic stem cells, the pig presents several challenges as compared with mice and humans.

Somatic, inactivating PIGA mutations in haematopoietic stem cells, followed by an unknown autoimmune selection process in favor of the mutated clone, are thought to be important events in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH). Recently, a second clonal event involving the HMGA2 gene was reported in some PNH cases, and over expression of this gene was postulated to promote proliferation of the mutated clone.

Treatment of ethmoid sinus osteoma is surgical. One case with orbital extension is reported and discussed. A 30 years-old male; complaining of swelling of themedial angle of the right eye. Computed tomography showed a right ethmoidal process with orbital extension. The tumor was removed through an external ethmoidectomy.

Recently, transdermal drug delivery system (TDDS) has become a more and more important approach to administering drugs. Based on its advantages, which are not achievable by other modes of administration, many researchers are dedicated to the study of it, and have made great progress. Although the skin offers a painless interface for systemic drug delivery, it also presents limitations which are mainly caused by the stratum corneum.

A prospective case-control study was undertaken to evaluate the association of inner segment-ellipsoid (ISel) band disruption with severity of diabetic retinopathy on spectral-domain optical coherence tomography. ISel disruption was graded as - grade 0: intact ISel; grade 1: focal disruption (subfoveal ISel disruption) and grade 2: global disruption (ISel disruption involving macular cube). Increased severity of diabetic retinopathy was found to be associated with increase in disruption of ISel (r = 0.49, p < 0.001).
