- Background: Near-infrared spectroscopy of the thenar eminence (NIRSth) is a non-invasive bedside method for assessing tissue oxygenation. The vascular occlusion test (VOT) with a pressure cuff can be used to provide a dynamic assessment of the tissue oxygenation response to ischaemia. VOT has been applied to assess the microcirculation by NIRSth in critically ill patients. The optimal mode of performing such VOT, however, remains controversial. Design, participants and setting: Prospective observational study among a cohort of 11 healthy volunteers in a tertiary intensive care department. Intervention: Measurement of NIRS-derived parameters using 1-, 2- and 3-minute VOTs or VOT to 40% tissue oxygen saturation (StO(2)). Main outcome measure: Changes in StO(2) and tissue haemoglobin index (THI) over time, and relative change from baseline for StO(2) and THI. Results: Mean baseline StO(2) was 80% (SD, 5%) and mean THI was 13.7 (SD, 1.9). The lowest StO(2) at the end of the VOT was 39% (SD, 13%) and 39% (SD, 2%) in the 3-minute and the 40% StO(2) VOTs, respectively. The duration of the 40% StO(2) VOT ranged from 1:35 to 8:21 minutes (median, 3:29 min). There was a difference between the StO(2) curves for the 3-minute and 40% StO(2) VOT (P = 0.005) but not the THI curves. Reported pain score was a median of 3.5 (IQR, 2.5-5.5) and 4 (IQR 2-4) for the 3-minute and 40% StO(2) VOTs, respectively. Conclusions: The 3-minute VOT and the 40% StO(2) appear equivalent. However, the 3-minute VOT carries a degree of decreased patient discomfort and shorter overall duration of execution.

- INTRODUCTION:This study investigated whether heads of state commonly regarded as dictators have a higher prevalence of partially treated supralabial hirsutism (PTSLH), commonly called a moustache, than non-dictatorial states. Design: retrospective observational study. Setting: the world political arena from 1901 to 2000. Participants: cohort of 139 dictators, 122 preceding political leaders in the respective countries, 122 succeeding political leaders also in the respective countries, as well as 76 Nobel peace prize laureates as controls. Interventions: none. Main outcome measures: the prevalence of PTSLH was 122 preceding political leaders.RESULTS: Of 139 dictators 49 (35%) demonstrated photographic evidence of PTSLH, while 85 (61%) did not. Of 48 preceding leaders 22 (46%) had PTSLH (p = 0.18 compared to dictators); of 33 following leaders ten (30%) had PTSLH (p = 0.59 compared to dictators). Finally of 78 Nobel peace prize laureates 31 (40%) had PTSLH (p = 0.47 compared to dictators).CONCLUSIONS: Most dictators did not have PTSLH. Moreover, the prevalence of PTSLH among dictators did not differ from controls. These data do not lend support to the commonly held notion that PTSLH is a predictor of a future dictatorial political career. Electorates the world over can now support political candidates with PTSLH without increased fear of becoming victims of a dictatorial system or having an increased risk of mortality after their ascent to power.
