Retractable type fall arresters constitute a most effective group of components used in personal protection systems protecting against falls from a height. They are designed primarily for outdoor use, which results in exposure to atmospheric factors associated with risk of corrosion of metal elements. This paper presents the results of a study, in which retractable type fall arresters were exposed to a simulated corrosive environment, a neutral salt spray. It discusses the development of corrosion processes depending on the duration of exposure to corrosive conditions. Tests demonstrated that corrosion of elements decreased their strength and impaired the functioning of mobile parts. The article presents methods of testing the correct functioning of devices, necessary for assessing their resistance to corrosion, which have been developed for this purpose. It also analyzes the correlation between corrosion-related damage of retractable type fall arresters and potential hazards for their users.

Duane retraction syndrome (DRS) is complicated to treat due to its wide spectrum of clinical presentations and the treatment of choice varies among surgeons. To provide insight into this challenging condition, we evaluated the long-term surgical outcomes of esotropic DRS type 1. The surgical motor success, defined as a horizontal deviation of 8 prism diopters (PD) or less, was found in 77.

Background: Chronic postoperative pain (CPOP) is among the main consequences of surgical procedures, directly affecting the quality of life. Although many strategies have been used to treat this symptom, they are often ineffective. Thus, studies investigating CPOP-associated mechanisms may help to develop more effective treatment strategies.
