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.

[Pelvic circulation in the pregnant woman].

The authors point out the fact that there are few publications on this subject. Besides variations related to functional and hormonal associated with pregnancy, temporary variations occur in the venous system and which take the form of the development of extra-intra pelvic anastomoses at several sites.

[Spontaneous dissection of the internal carotid artery].

Spontaneous dissections of internal carotid artery are known from more than 30 years and their incidence is now specified, several hundred cases being published. The case reported here illustrates very well the setting problems of this disease and explains why the incidence of the mild forms has been underestimated. The case of a sixty years old man with vague vertiginous feeling, headache and moderate ocular troubles is presented.

[The anatomic basis of vascular malformations].

Basing themselves on anatomical and embryological considerations, the authors suggest a distinction between angiodysplasias and abnormalities. They define the characteristics proper to these varieties and establish the bases of therapeutic inferences. They briefly recall the lymphatic malformations.

The organogenesis and anatomy of vascular malformation.

According to an embryological basis, the Authors analyze the development of the vascular system and try to establish a differentiation between angiodysplasias and abnormalities. They define the characteristics of each group and make an attempt at classification. The major characteristics of differentiation are the evolutional aspects and the presence of arteriovenous fistulas.

[Phlebology and gynecology].

The authors give the pattern of several situations where are added phlebological and gynecological diseases. They summarize the several treatments and the practical uses for this. Medicolegal viewpoints are also taken in account.

[Intra- and extra-pelvic venous connections. Anatomical study].

Regarding to clinical diseases, the authors emphasize the important part of pelvic veins as collateral flows when iliac channels are occluded. They point out the three mains streams of this collateral network: the obturator veins, the gluteal veins, and the pudendal veins. Longitudinal anastomoses are connected each other by transversal veins such as Santorini plexus, and sacral veins; they allow venous supply from one side to the other when two levels or more are involved.

[Interosseous dorsal artery of the first intermetatarsal space: anatomic variations and value in functional vascular studies].

The first dorsal metatarsal artery (MDA) is usually described as the last collateral branch of dorsalis pedis artery (DPA, which anastomoses with the lateral plantar branch of the posterior tibial artery (PTA). Doppler assessment on DMA of a flow does not always mean that DPA is free, but may show a functional plantar arch. The aim of this study was to determinate the patency rate of this plantar arch and to appreciate the part of DPA in the vascularisation of the foot.

[Vascular thrombosis and oral contraceptives].

In reference to four particular cases where a venous thrombosis associated with the use of oral contraceptives, the authors review the various factors of this problem. The importance of the concomitant use of tobacco as well as risk factors such as hyperlipidemia and hypertension, are especially stressed. These four cases, almost of an experimental nature, permit to correlate precisely the interaction between estro-progestative medications and the occurrence of venous thromboses.

[Anatomical organization, organogenesis and innervation of the arteries of the hand].

The authors sum up the anatomical aspects of the arteries of the hand. They emphasise the fact that, by the side of the classical description; there is a lot of variations. These can be explained by organogenesis, showing that hand arteries pass over several stages, before reaching the terminal one.

[Hypoplasia of the abdominal aorta. Review of the literature apropos of 4 cases].

The authors report 4 cases of abdominal aortic hypoplasia and, reviewing the literature, recall the anatomical classifications and the clinical aspects predominated by arterial hypertension and arterial claudication. Pathogenesis does not seem to be univocal and some arguments are in favor of a congenital origin when others plead for an acquired inflammatory disease. But above forty one must consider the possible responsibility of added atheroma.
