Is psoriasis contagious ?
No. For instance, you can go without any risk to the swimming pool when your suffer from psoriasis. On the contrary, skins affected by psoriasis contain much more anti-infectious molecules than a normal skin. The risk is consequently lower.
Is psoriasis hereditary ?
This is a frequent question as psoriasis is a genetical disease. However, the transmission does not occur in a mathematical way involving one specific gene, but because of predisposition factors. A similar situation arises when a mother suffers from hay fever. Her children are likely to develop this disease, but nothing is statistically predictable. This concern about the children often grows in a case of severe psoriasis. It has to be reminded that when you mix your genes with those of another parent who is not affected by the disease, your children can only have, at worst, a more moderate form of psoriasis. Also, treatments are becoming increasingly efficient, which is a opportunity for us to stop perceiving psoriasis as a curse passed on from generation to generation.
If the cure is not working well, do I have to see another doctor ?
As the symptoms of psoriasis differ for each individual, the patients benefits from a priceless insight giving them information a doctor cannot know. Any patient willing to improve their condition have to communicate consistently about the evolution of their disease in order to enable their doctor to adjust the treatment progressively. Hence, it is a mistake to change your physician since it will make you start from scratch. Thus, it seems better to be patient enough to explain regularly to your doctor why you still are dissatisfied with your current treatment, so that he or she eventually finds the ideal one. This is all the more significant as no pratictioner can have an exhaustive knowledge, especially in the case of a disease that flares up differently for each patient.

A cross-sectional analysis of skin cancer risk in patients receiving narrow-band ultraviolet B phototherapy: an evaluation of 100 patients.
Arch. Dermatol. Res..
2020 May , 312, (4):249-253.
Narrow-band ultraviolet B (NB-UVB) phototherapy is an effective and widely used treatment modality for psoriasis and other inflammatory skin diseases. The carcinogenic effect of PUVA treatment has been investigated extensively, but there is very scarce data about the role of NB-UVB in the development of skin cancer. The aim of this study was to investigate the potential carcinogenic risk of NB-UVB therapy in various skin disorders. In this cross-sectional study, we evaluated 100 patients (...)

A potential association between psoriasin to rs4819554 of IL-17RA gene polymorphism in psoriasis Egyptian patients.
Arch. Dermatol. Res..
2020 May , 312, (4):273-281.
Interleukin 17 (IL-17) is one of the pro-inflammatory cytokine. Psoriasin is a noticeably over-expressed protein found in the skin lesions of psoriatic patients. Our current study was planned to examine the association of (- 947 A/G) single nucleotide polymorphism (SNP) in IL-17RA promoter region (rs4819554) with psoriasis susceptibility in Egyptian psoriatic patients. Our study included 100 patients and 100, age as well as sex matched, control groups. IL-17RA SNP association was studied (...)

Repurposing an old drug for new use: Niclosamide in psoriasis-like skin inflammation.
J. Cell. Physiol..
2020 Jun , 235, (6):5270-5283.
Drug discovery is an onerous, extremely expensive, and time-consuming process. Instead, drug repurposing is an attractive strategy for exploiting novel indications for a drug beyond its original use. The untapped potential of drug repurposing compensates the barriers associated with the drug discovery pipeline. Psoriasis is an autoimmune skin disease, where hyperproliferation of keratinocytes and exaggerated immune responses are the important hallmarks of the disease. Extensive in vitro and (...)

Drug delivery system of dual-responsive PF127 hydrogel with polysaccharide-based nano-conjugate for textile-based transdermal therapy.
Carbohydr Polym.
2020 May 15, 236:116074.
Pluronic F-127 based dual-responsive (pH/temperature) hydrogel drug delivery system was developed involving polysaccharide-based nano-conjugate of hyaluronic acid and chitosan oligosaccharide lactate and applied for loading of gallic acid which is the principal component of traditional Chinese medicine Cortex Moutan recommended in the treatment of atopic dermatitis. The polysaccharide-based nano-conjugate was used as pH-responsive compound in the formulation and its amphiphilic character (...)

Skin of atopic dermatitis patients shows disturbed β-glucocerebrosidase and acid sphingomyelinase activity that relates to changes in stratum corneum lipid composition.
Biochim Biophys Acta Mol Cell Biol Lipids.
2020 Jun , 1865, (6):158673.
Patients with Atopic Dermatitis (AD) suffer from inflamed skin and skin barrier defects. Proper formation of the outermost part of the skin, the stratum corneum (SC), is crucial for the skin barrier function. In this study we analyzed the localization and activity of lipid enzymes β-glucocerebrosidase (GBA) and acid sphingomyelinase (ASM) in the skin of AD patients and controls. Localization of both the expression and activity of GBA and ASM in the epidermis of AD patients was altered, (...)

Physiology and Pathophysiology of Itch.
Physiol. Rev..
2020 Jul 01, 100, (3):945-982.
Itch is a topic to which everyone can relate. The physiological roles of itch are increasingly understood and appreciated. The pathophysiological consequences of itch impact quality of life as much as pain. These dynamics have led to increasingly deep dives into the mechanisms that underlie and contribute to the sensation of itch. When the prior review on the physiology of itching was published in this journal in 1941, itch was a black box of interest to a small number of neuroscientists (...)
