Composition of minerals and trace elements at Mamasani thermal source: A possible preventive treatment for some skin diseases

Thiol-Disulphide Homeostasis, Ischemia-Modified Albumin, Trace Elements and Vitamins in Vitiligo Patients

Background

Vitiligo, a multifactorial, depigmented skin disease, is characterised by selective loss of functional melanocytes leading to pigment reduction in the affected areas of the skin.

Aim

We aimed to examine thiol-disulphide homeostasis, IMA, copper, zinc, selenium, vitamin A and vitamin C levels in vitiligo patients.

Materials and Methods

The study included 83 vitiligo patients and 72 healthy controls. Copper, zinc, and selenium levels were measured by atomic absorption spectrophotometer; vitamin A and E levels were measured by high-performance liquid chromatography. Ischemia-modified albumin and native/total thiol levels were measured by colourimetric method.

Results

Serum native and total thiol levels were significantly lower in vitiligo patients (P < 0.001, for all). Zn levels were significantly higher in vitiligo patients than in the control group (P = 0.004). There was no statistical difference in terms of Cu, Se, vitamin A and vitamin E levels.

Conclusions

All thiol-disulphide homeostasis parameters (the most important antioxidant-oxidant system in circulation), trace elements, and vitamins together were evaluated in the present study in vitiligo patients. It can be concluded that vitiligo patients have increased oxidative stress status, and also the increase in the dissemination of the disease also increases the oxidative stress in the body.

Hydrogen sulfide (H2S) - therapeutic relevance in rehabilitation and balneotherapy Systematic literature review and meta-analysis based on the PRISMA paradig

Background. An active molecule in sulfurous mineral - therapeutic waters and also in sapropelic mud is H2S, a hormetic gaseous molecule that can actively penetrate the skin. While high levels of H2S are extremely toxic, low levels are tolerated and have potential cytoprotective effects, with anti-inflammatory and antioxidant applications. Objective. This systematic review aims to rigorously select related articles and identify within their content the main possible uses of hydrogen sulfide from balneary sources and to explain its physiological mechanisms and therapeutic properties. Methods. To elaborate our systematic review, we have searched for relevant open access articles in 6 international databases: Cochrane , Elsevier , NCBI/PubMed , NCBI/PMC , PEDro , and ISI Web of Knowledge/Science , published from January 2016 until July 2021. The contextually quested keywords combinations/ syntaxes used are specified on this page. The eligible articles were analyzed in detail regarding pathologies addressed by hydrogen sulfide. All articles with any design (reviews, randomized controlled trials, non-randomized controlled trials, case-control studies, cross-sectional studies), if eligible according to the above-mentioned selection methodology, containing in the title the selected combinations, were included in the analysis. Articles were excluded in the second phase if they did not reach the relevance criterion. Results. Our search identified, first, 291 articles. After eliminating the duplicates and non-ISI articles, remained 121 papers. In the second phase, we applied a PEDro selection filter, resulting in 108 articles that passed the relevance criterion and were included in this systematic review. Conclusions. H2S biology and medical relevance are not fully understood and used adequately for sanogenic or medical purposes. More research is needed to fully understand the mechanisms and importance of this therapeutic gase. The link between balneotherapy and medical rehabilitation regarding the usage of hydrogen sulfide emphasises the unity for this medical speciality.

The Role of Thermal Water in Chronic Skin Diseases Management: A Review of the Literature

The benefits of thermal water in different diseases have been known since ancient times. Over the past decades, a re-assessment of the use of mineral water for the treatment of several pathologic conditions has taken place around the world. Today, water therapy is being practiced in many countries that have a variety of mineral springs considerably different in their hydrogeologic origin, temperature, and chemical composition. Thermal water and balneotherapy offer several advantages: this approach needs no chemicals or potentially harmful drugs; there are almost no side effects during and after treatment, and there is a low risk to the patient’s general health and well-being. However, it is difficult to evaluate the efficacy of this therapeutic approach in clinical practice due to the complexity of molecular mechanisms underlying its efficacy. Here we review the current knowledge of the chemical, immunological, and microbiological basis for therapeutic effects of thermal water with a specific focus on chronic inflammatory skin diseases. We also describe recent evidence of the major dermatologic diseases that are frequently treated by balneotherapy with a remarkable rate of success. Moreover, we discuss the potential role of balneotherapy either alone or as a complement to conventional medical treatments.

Chemical Peeling as an Innovative Treatment Alternative to Oral Antifungals for Onychomycosis in Special Circumstances

Toe nail onychomycosis (ONM) is a common problem in elderly patients. Treatment in diabetic patients with associated comorbidities such as congestive heart failure becomes a challenge. Oral antifungals are best avoided owing to most of them being contraindicated or unsafe due to comorbidities and/or risk of drug interactions stemming from polypharmacy. Topical agents alone are not effective. Unlike isolated ONM in healthy and younger patients, ONM involving multiple nails in geriatric and diabetic patients warrants treatment as it serves as a source of recurrent tinea of the feet and other sites, and even contributes to formation of diabetic foot ulcers. Long-pulsed Nd:YAG and fractional CO>sub<2>/sub< laser (in addition to antifungals) have been reported to provide gratifying results in toe nail ONM. But high treatment cost is a major limitation. Nail peeling with glycolic acid (GA) and low-concentration croton-oil free phenol (CFP) peels have been used in different nail conditions but not specifically for ONM. We report the successful use of Black peel (a superficial-to-medium depth peel used typically for anti-acne and cosmetic indications), a combination of 50% black acetic acid, 0.5% salicylic acid, 6% tetrahydrojasmonic acid, 10% bio sulphur, and 0.1% potassium iodide, in two difficult cases with ONM of multiple nails, the rationale of use being the additional anti-fungal effects of all the peel components.

Phylogenetic diversity and metabolic potential of microbiome of natural healing clay from Chamliyal (J&K)

Clay therapy for skin disease treatment is an ancient practice popular worldwide as a cheap alternative to pharmaceutical products. Effectiveness of clay against skin problems has been linked to its mineral composition and to microbial activity. The clay-water paste of a holy shrine Chamliyal in the Jammu region of J&K, India is used as an ointment to treat different skin disorders particularly psoriasis. Using the 16 SrDNA amplicon pyrosequencing and whole-metagenome direct shotgun Illumina sequencing, microbial phylogeny and potential metabolic functions were catalogued for Chamliyal's clay. Microbial diversity profile of the Chamliyal's clay is similar to other medicinal clays, particularly Dead Sea; there is some uniqueness as well. Although Proteobacteria, Actinomycetes and Firmicutes are common inhabitants of all the clay types, sulphur- and iron-reducing bacteria like Deferribacterales are particular to clays used for skin healing. In the present study it is proposed that healing properties of clay may be due to the microbes and microbial genes associated with metabolism of minerals like iron and sulphur, that lead to mineral acquisition in the Chamliyal's clay.
