Generating Loco-Regional Heat Impact - Available Technologies: Their Specific Efficacy and Inherent Restrictions- Juniper Publishers

Juniper Publishers-Journal of Complementary Medicine

Introduction

Generally regarded the critical claim in hyperthermia is the ability to achieve a relevant heat impact in the region of interest. As opposed to surface heating it appears quite tricky to come up with valid predictions for a region of interest (ROI) located in the volume depth of a body.
Despite most encouraging results from recent clinical trials there exists still skepticism. One main argument is the difficult reproducibility of a desired temperature impact in the ROI - simultaneously the application should in clinical routine be practically feasible and affordable.


Objective

Focusing on non invasive hyperthermia technologies the discussion is led by the following issues

a) What are realistic claims in achievable temperature impact? Which restrictions do exist? Which safety mechanisms do exist?
b) What are the characteristics in clinical procedures and for the business concept of a supplying healthcare unit?


Discussion

Different available technologies are briefly presented and their technical characteristics are discussed. Focus will be on the non invasive methods of antenna systems and capacitive electro-hyperthermia. This will cover potential impact as well as specific restrictions.
Much work worldwide has been invested in trying to achieve quality procedures in terms of monitoring temperature in the ROI. Ideally this should be an equally non invasive mechanism. Available methods to this objective will be discussed with their specific benefits and restrictions.


Conclusion

To be as precise in application and monitoring a heat dose as individually desirable an immense effort (in time and in investment) is required. Some compromises seem acceptable in order to spread hyperthermia to a scalable supply for a population´s potential need. An awareness of realistic claims and restrictions of the various technologies is helpful in gaining realistic expectations and consecutively an acceptance among clinicians.

Nutraceuticals Potential of Petroselinum Crispum: A Review- Juniper Publishers

Image
Juniper Publishers- Journal of complementary medicine Petroselinum crispum is a green biennial hedge plant which belongs to Apiaceae family indigenous to Europe and Western Asia. Flavonoids like apigenin, chrysoeriol and quercetin are chief components in Petroselinum crispum plant that decrease the oxidative damage associated with cancer, aging, atherosclerosis, ischemic damage, soreness, and neurodegenerative diseases. Leaves, seeds and roots of Petroselinum crispum are used as hepatoprotective, brain protective, anti-diabetic, analgesic, spasmolytic, immunosuppressant, anti-anemic, menorrhagia, anti-coagulant, anti-hyperlipidemic and many more diseases. This paper put a light on bioactive and nutraceuticals properties of Petroselinum crispum . Keywords: Petroselinum crispum ; Anti-oxidant; Bioactive compounds; Nutraceuticals Introduction Petroselinum crispum (Parsley) is an herbal plant which belongs to Apiaceae family indi...

Traditional and Complementary Medicine: Where Are We?-Juniper Publishers

Image
Juniper Publishers As physical fitness and healthy diet not very easy to obtain and maintain, interest in Traditional and Complementary Medicine (TCM) is growing wider day by day. There are lots of synonym terms globally, but Turkish Ministry of Health accepts TCM officially. National Center for Complementary and Integrative Health (NCCIH) divides TCM approaches into two main groups [1]: I. Natural products II. Mind and body practices Among natural products there are herbs, vitamins and minerals or dietary supplements. These are the most common approaches in USA as well as the other countries [2]. In the second group, there are yoga, chiropractice, acupuncture, etc. Besides these two groups, there are also some other practices such as homeopathy, nathuropathy and ayurveda. World Health Organization (WHO) promotes the interventions that both improves the quality and standardization and also facilitates the integration to health care systems [3]. WHO reports that in 80% of m...

Parental and Physician Perceptions of Medical Marijuana in the Pediatric Setting-Juniper Publishers

Image
Juniper Publishers Objective:  The past decades have seen several political and sociological debates regarding the legalization of medical marijuana as studies discover novel treatment benefits. In the pediatric setting, these discussions involve both parents and physicians. This study sought to identify factors that may influence the parents’ and physicians’ perceptions on medical marijuana use for children; and to determine any stigmas and concerns with its use.  Methods:  A prospective survey using a 5-point Likert scale was administered using convenience sampling of guardians with children receiving care in the pediatric emergency department, physicians working in the pediatric hospital, and providers attending the 2016 Pediatric Academic Societies Conference.  Results:  319 parents and 287 physicians participated in this study. The majority of parents were female (69.3%), white (44.2%) and 35-44 years (34.2%). The majority of physicians were female (5...
