Pulmonary artery sling (PAS) is a rare congenital anomaly frequently accompanied by focal or long-segment tracheal stenosis. We presented a 34-year-old female patient with severe long-segment tracheal stenosis associated with PAS which was assessed with Multi Slice Computed Tomography (MSCT) consisting of axial, three dimensional and virtual bronchoscopic images of the airway. This case report discussed the management of her difficult airway condition during surgical cholecystectomy and thyroidectomy by using proseal- LMA and I-gel, respectively (Fig. 4, Ref. 10).

AAA repair is associated with high rate of mortality and morbidity. Oesophageal Doppler (OED) can offer a less invasive cost-effective tool for intraoperative monitoring of haemodynamic changes. The aim of the study was to confirm the benefits of haemodynamic optimisation in patients undergoing AAA repair using OED monitoring. We assumed that haemodynamic parameters of patients with OED would be better optimised; they would probably get more fluids during the operation, and their ICU and hospital stay would be shorter as a result of having fewer postoperative complications and lower mortality. ⋯ The haemodynamic monitoring by oesophageal Doppler can improve the outcome of patients with AAA repair (fewer major complications, shorter ICU and hospital stay) (Tab. 4, Fig. 4, Ref. 25).

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).
