The course of the brachial plexus, its relations with surrounding structures and unique primary and secondary divisions result in its wide range of anatomical variations. Most of these variations were detected during anatomical dissections and studies. It has been found that 53% of studied brachial plexuses contained variations. The communication between musculocutaneous and median nerves is the most common variation of infraclavicular part of brachial plexus. ⋯ Variable interconnections between musculocutaneous and median nerve have to be considered in diagnosis of nerve lesions in axillary and arm regions. Compound musculocutaneous and median nerve neuropathy would occur in lesions of the interconnecting branches. Injuries of musculocutaneous nerve proximal to these branches can cause particular and unexpected symptoms, such as weakness of forearm flexors and thenar muscles (Fig. 6, Ref. 28).

This study presents an empirical evidence of benefit of narrative video clips in embedded virtual reality websites of hotels for relieving travel anxiety. Even though it was proven that virtual reality functions do provide some relief in travel anxiety, a stronger virtual reality website can be built when narrative video clips that show video clips with narration about important aspects of the hotel. We posit that these important aspects are 1. ⋯ Thus we created a video clip that showed and narrated about the escape route from the hotel room, another video clip that showed and narrated about surrounding neighborhood. We then conducted experiments with this enhanced virtual reality website of a hotel by having human subjects play with the website and fill out a questionnaire. The result confirms our hypothesis that there is a statistically significant relationship between the degree of travel anxiety and psychological relief caused by the use of embedded virtual reality functions with narrative video clips of a hotel website (Tab. 2, Fig. 3, Ref. 26).

An objective of our work was to clarify variations in pudendal nerve formation, as well as their possible impact on the clinical picture. Bilateral pudendal nerve course and formation was studied on 20 adult cadavers. Anterior approach was used in 15 of them, both posterior and anterior approaches were used in five of them. ⋯ We observed its branching before entering the pudendal canal in 15 cases (75 %). It has divided in the pudendal canal in other cases. This description may be useful particularly for the pudendal nerve block and the nerve saving surgeries directed on the relevant region (Fig. 8, Ref. 24).

The main aim of the early treatment of polytrauma is recovery of patient's physiological functions. The early achievement of therapeutic goals, mainly adequate tissue perfusion and repayment of oxygen debt, are postulated. The aim of the study was to confirm whether blood lactate level as a quantifier of oxygen deficit, as well as normalization of blood lactate level within the first 24 hours, have an impact on the mortality and morbidity of seriously injured patients. ⋯ The patients, who repaid oxygen debt within first 24 hours, have lower morbidity and mortality (Tab. 6, Ref. 19).

Male infertility is one of the most stressful factors of couples, being present in about 40% cases. It is usually caused by a low number of sperm (oligozoospermia) or poor sperm motility (asthenozoospermia). The sperm motility is used as an indicator of semen quality and male infertility. To the impairment of male reproduction health can contribute genetic, nutritional and environmental factors, smoking and drugs. It is well documented that excessive reactive oxygen species (ROS) production decreases sperm motility, impairs sperm function, damages the morphology of spermatozoa (1, 2). To the decreased sperm motility contribute also disturbances of sperm mitochondrial function and energy production, low levels of coenzyme Q10 and carnitine, as well as sperm mitochondrial deoxyribonucleic acid (DNA) defects. The origin of sperm dysfunction, however, is not well understood. ⋯ We suppose that incorporation of oxidative stress assessment, CoQ10-TOTAL and α-tocopherol concentrations in seminal fluid and plasma into routine andrology can play an important role for the diagnosis and targeted therapy of male infertility (Tab. 1, Ref. 16).
