1 ALBA-R: LoadBalancing Geographic Routing Around Connectivity Holes in Wireless Sensor Networks This paper presents ALBA-R, a protocol for convergecasting in wireless sensor networks. ALBA-R features the cross-layer integration of geographic routing with contention-based MAC for relay selection and load balancing (ALBA) as well as a mechanism to detect and route around connectivity holes (Rain...

Pityriasis rosea is a short-lived rash that commences initially as a large so-called ‘herald’ patch followed by a rapidly evolving eruption on the trunk and extremities. Characteristic pattern of lesions follow the lines of cleavage in a ‘christmas tree’ distribution. PR is most frequently seen between first and third decade but a range of 3 month to 83 years were reported. The incidence doesn’...

The Salix alba L. (white willow)—Salix fragilis L. (crack willow) complex includes closely related polyploid species, mainly tetraploid (2n = 4x = 76), which are dioecious and hence obligate allogamous. Because little is known about the genome constitution and chromosome behavior of these pure willow trees, genetic analysis of their naturally occurring interspecific polyploid hybrids is still v...

The etiology of pityriasis lichenoides is unknown. One of the accepted theories admits that PL is an inflammatory response to extrinsic antigens such as infectious agents, drugs and vaccines. In recent medical literature, only the MMR vaccine (Measles, Mumps and Rubella) was associated with the occurrence of this disease. We present a case of a male, 12 year old healthy patient who, five days a...

Treatment of pityriasis rubra pilaris is still challenging. We here present a 74-year-old woman who had not experienced stable remission of her skin symptoms during prior treatments including topical and systemic corticosteroids, phototherapy, orally administered acitretin, cyclosporine, methotrexate and adalimumab. A therapy with oral alitretinoin was started and tolerated very well. After a f...

One hundred and twenty-six cases of pityriasis rosea seen over two years in north Staffordshire were analysed for clustering in time and space. A statistically significant degree of clustering was found; this was evident among female patients considered separately but not among male patients. The incidence of the condition was higher in patients working in, or attending, educational establishme...

Introduction: Skin diseases can adversely affect the quality of life an individual. Adolescence is acritical time in biophysical development and adverse skin conditions during this period alter thegrowth self-confidence self-esteem social engagement. Purpose: The present study wasdesigned to assess burden, pattern their impact on inadolescent students. Materials Methods: A total 23 schools havi...

Oxidative stress and Ultraviolet (UV) irradiation-induced skin damage, is involved in numerous diseases. Eclipta alba which belongs to Asteraceae family is used traditionally in Ayurvedic system of medicine in India for the treatment of liver diseases. Our study shows that water extract of E. alba has a potent effect in scavenging 1, 1-diphenyl-2-picrylhydrazyl (DPPH), chelating ferrous ion, an...

In this case report, we present a 30-year-old man who developed pityriasis rubra pilaris (PRP) following exposure to Dolomite. The diagnosis of PRP was confirmed histologically and the patient was successfully treated with acitretin and cyclosporine.
