Even mildly impaired MS patients who are not markedly depressed have to deal with problems of body image. Improvement of body image perception in MS patients taking gender-specific differences into account represents a promising area of future psychological research.

The literature leads us to assume that people suffering from tinnitus may also have negative feelings about their body concept and body image. This pilot study aimed to investigate patients with chronic tinnitus for the presence of disturbed body concept and body image, taking into account the subjective degree of distress and any depression. Sixty-five patients with chronic tinnitus (members of a support group) were interviewed concerning the subjective distress caused by their tinnitus, their body image and any depression. Overall, the study collective showed significantly less "vitality and body dynamics," "attractiveness/self-confidence" and was less pleased with "emphasis on the appearance of one's own body" than was a predetermined random sample of healthy controls. Comparison of those patients reporting severe tinnitus and those with mild tinnitus showed the former to suffer from significantly greater "uncertainty and concern" with regard to their bodies. In practice, problems involving a person's body image should be given greater consideration during examination and when planning treatment and, for example, therapy should incorporate body-related exercises.

This trial evaluates whether nocturnal oxygen therapy (NOT) during a stay at 2048 m improves altitude-induced exercise intolerance in lowlanders with chronic obstructive pulmonary disease (COPD). 32 lowlanders with moderate to severe COPD, mean ± SD forced expiratory volume in the first second of expiration (FEV1) 54 ± 13% predicted, stayed for 2 days at 2048 m twice, once with NOT, once with placebo according to a randomized, crossover trial with a 2-week washout period at < 800 m in-between. Semi-supine, constant-load cycle exercise to exhaustion at 60% of maximal work-rate was performed at 490 m and after the first night at 2048 m. Endurance time was the primary outcome. Additional outcomes were cerebral tissue oxygenation (CTO), arterial blood gases and breath-by-breath measurements (http://www.ClinicalTrials.gov NCT02150590). Mean ± SE endurance time at 490 m was 602 ± 65 s, at 2048 m after placebo 345 ± 62 s and at 2048 m after NOT 293 ± 60 s, respectively (P < 0.001 vs. 490 m). Mean difference (95%CI) NOT versus placebo was − 52 s (− 174 to 70), P = 0.401. End-exercise pulse oximetry (SpO2), CTO and minute ventilation ($${\dot{\text{V}}}_{{\text{E}}}$$ V ˙ E ) at 490 m were: SpO2 92 ± 1%, CTO 65 ± 1%, $${\dot{\text{V}}}_{{\text{E}}}$$ V ˙ E 37.7 ± 2.0 L/min; at 2048 m with placebo: SpO2 85 ± 1%, CTO 61 ± 1%, $${\dot{\text{V}}}_{{\text{E}}}$$ V ˙ E  40.6 ± 2.0 L/min and with NOT: SpO2 84 ± 1%; CTO 61 ± 1%; $${\dot{\text{V}}}_{{\text{E}}}$$ V ˙ E  40.6 ± 2.0 L/min (P < 0.05, SpO2, CTO at 2048 m with placebo vs. 490 m; P = NS, NOT vs. placebo). Altitude-related hypoxemia and cerebral hypoxia impaired exercise endurance in patients with moderate to severe COPD and were not prevented by NOT.
