Introduction. Vertebral and cerebrospinal injury and its consequences constitute an important problem in modern medicine. In recent years, studies have shown that percutaneous electric stimulation in patients with these injuries can influence the neuronal networks of different parts of the spinal cord to activate afferent and efferent reflex connections with complete or partial disorders of supraspinal influences of various geneses. Aim. To investigate the effect of percutaneous electric stimulation of the spinal cord on the dynamics of recovery of neurological functions in children with vertebral and cerebrospinal injury. Materials and methods. Seven patients aged 4 to 18 years with lesions of the spinal cord from C5-C6 to Th12-L1 and who mainly had a marked neurological deficit were examined from 1 month to 9 years after surgical treatment. All patients underwent neurophysiological studies, including electroneuromyography, electromyography, and somatosensory-evoked potentials. The patients and their parents kept a diary of urination. Results. This clinical study showed that percutaneous electric stimulation of the spinal cord contributed to the rapid and complete restoration of the neurological functions in patients with vertebral and medullar conflict and depended directly on the early terms of surgical intervention. Conclusion. The positive results obtained in the complex rehabilitation of children with vertebral and cerebrospinal injuries by using non-invasive percutaneous electric stimulation of the spinal cord support the use of this method in the early stages after surgical intervention.

In recent years, polyphenols have been extensively studied due to their antioxidant, anticancer, and anti-inflammatory properties. It has been shown that anthocyanins, flavonols, and flavan-3-ols play an important role in the prevention of bacterial infections, as well as vascular or skin diseases. Particularly, resveratrol, as a multi-potent agent, may prevent or mitigate the effects of oxidative stress. As the largest organ of the human body, skin is an extremely desirable target for the possible delivery of active substances. The transdermal route of administration of active compounds shows many advantages, including avoidance of gastrointestinal irritation and the first-pass effect. Moreover, it is non-invasive and can be self-administered. However, this delivery is limited, mainly due to the need to overpassing the stratum corneum, the possible decomposition of the substances in contact with the skin surface or in the deeper layers thereof. In addition, using resveratrol for topical and transdermal delivery faces the problems of its low solubility and poor stability. To overcome this, novel systems of delivery are being developed for the effective transport of resveratrol across the skin. Carriers in the micro and nano size were demonstrated to be more efficient for safe and faster topical and transdermal delivery of active substances. The present review aimed to discuss the role of resveratrol in the treatment of skin abnormalities with a special emphasis on technologies enhancing transdermal delivery of resveratrol.

Effects Of Temperature

Over the past decade, research interest has risen on the direct effects of temperature on exercise capacity and tolerance, particular in the heat. Two major paradigms have been proposed for how hyperthermia may contribute to voluntary fatigue during exercise in the heat. One suggests that voluntary exhaustion occurs upon the approach or attainment of a critical internal temperature through impairment in a variety of physiological systems. An alternate perspective proposes that thermal inputs modulate the regulation of self-paced workload to minimize heat storage. This review seeks to summarize recent research leading to the development of these two models for hyperthermia and fatigue and explore possible bridges between them. Key areas for future research and development into voluntary exhaustion in the heat include (i) the development of valid and non-invasive means to measure brain temperature, (ii) understanding variability in perception and physiological responses to heat stress across individuals, (iii) extrapolating laboratory studies to field settings, (iv) understanding the failure in behavioural and physiological thermoregulation that leads to exertional heat illness, and (v) the integration of physiological and psychological parameters limiting voluntary exercise in the heat.

In human obstetrics, placental vascularisation impairment is frequent as well as linked to severe pathological events (preeclampsia and intrauterine growth restriction), and there is a need for reliable methods allowing non-invasive evaluation of placental blood flow. Uteroplacental vascularisation is complex, and animal models are essential for the technical development and safety assessment of these imaging tools for human clinical use; however, these techniques can also be applied in the veterinary context. This paper reviews how ultrasound-based imaging methods such as 2D and 3D Doppler can provide valuable insight for the exploration of placental blood flow both in humans and animals and how new approaches such as the use of ultrasound contrast agents or ultrafast Doppler may allow to discriminate between maternal (non-pulsatile) and foetal (pulsatile) blood flow in the placenta. Finally, functional magnetic resonance imaging could also be used to evaluate placental blood flow, as indicated by studies in animal models, but its safety in human pregnancy still requires to be confirmed.

Abstract Metastatic Spinal Cord Compression is a surgical emergency owing to its propensity to cause significant morbidity and mortality. Dexamethasone is prescribed to reduce oedema and promote vascular membrane stabilization. The is done so until a more definitive management has been performed. This is a retrospective study evaluating the steroid-prescribing practice for MSCC patients in 2018 at a tertiary spinal unit in Greater Manchester. Thirty-three patients who underwent stabilisation were evaluated in terms of both steroid prescribing and weaning practices. Standards used against for both were the NICE guidelines and the Edinburgh/Christie’s guidelines. Of the 33 patients evaluated, only 1 patient received the correct loading dose of 16mg, whilst 27 went straight to being given 8mg BD. 5 did not receive dexamethasone at all. In terms of discontinuation/weaning, 26 were weaned accordingly and 2 were not weaned to continue as adjuvant treatment. Dexamethasone prescribing practises has since improved over the past two years. 93% of the patients have been correctly weaned as compared to 38% in the past. In terms of prescription, much needs to be done as almost all the patients evaluated did not get the correct loading dose despite receiving the appropriate maintenance.

Decompression Stress

Decompression sickness (DCS) remains a major operational concern for diving operations, submarine escape and high-altitude jumps. Aside from DCS symptoms, venous gas emboli (VGE) detected with ultrasound post-dive are often used as a marker of decompression stress in humans, with a specificity of 100% even though the sensitivity is poor [1]. Being non-invasive, portable and non-ionizing, ultrasound is particularly suited to regular and repeated monitoring. It could help elucidate inter- and intra-subject variability in VGE and DCS susceptibility, but analyzing these recordings remains a cumbersome task [2].
