Handheld device quantifies breath acetone for real-life metabolic health monitoring.

Non-invasive breath analysis with mobile health devices bears tremendous potential to guide therapeutic treatment and personalize lifestyle changes. Of particular interest is the breath volatile acetone, a biomarker for fat burning, that could help in understanding and treating metabolic diseases. Here, we report a hand-held (6 × 10 × 19.

[The "rete venosum plantare" (the plantar venous network or Lejars' venous sole of the foot)].

Looking at the bibliography of the venous sole of the foot (Lejars), the authors point out the opposite convictions concerning this structure. For some ones, it doesn't exist, but fort the others, it is a very important network of tiny veins, such as it was described by Lejars himself. However, all this studies, are made upon cadavers, injected or not, and must be compared with results from living people by the mean of angiography, non invasive Vascular Assessment, or RMN, which take in account vasomotricity.

[Inter-related arterial and venous pathologies].

The authors concomitant arterial and venous disorders. On the same patient. They point out the obvious preeminence of arterial disease on venous ones, and discuss about the panel of therapy association usable.

[Structural and functional anatomical bases of deep venous insufficiency of the lower limbs].

The authors consider the Extent of the several anatomical structures which constitute the deep venous network, and the part they can take in the case of deep venous insufficiency. Congenital Vascular diseases are called back in mind when considering Embryology, and point out the extent of the deep venous state; such veins can gather in periarterial plexus, at the muscular Level, and in going past all along main arterial axes. Among all the critical points of these axes, we must keep the popliteal veins, the femoral crossing, and the iliocaval one and elsewhere, the important question of venous valves and communicating and perforating veins.

[Lumbar sympathectomy for arteritis. A reliable and (almost) seventy year-old technique].

The old procedure of lumbar sympathectomy has long been the only chance of avoiding amputation for arteritic patients. Its field of application has shifted as reconstructive surgery and medical therapy made progress, and it is no longer the only solution and has more precise indications. Proper evaluation of its chances of success according to the individual situations allows establishing its potential and limitations.
