Characteristics of the Stool, Blood and Skin Microbiome in Rosacea Patients.

Several research groups have confirmed that in the pathogenesis of the chronic inflammatory skin disorder rosacea, the composition of the skin and fecal microbiome of affected patients differs from that of healthy individuals. We studied the stool, blood and skin microbiomes of rosacea and control patients using 16S rRNA sequencing. Our goals were to determine 1.

[Dermatitis herpetiformis and other forms of wheat sensitivity].

Background: Wheat sensitivity is a collective term for several, especially gastrointestinal, diseases that occur as part of a hypersensitivity reaction after wheat consumption. The symptoms, which are mostly similar to those of irritable bowel syndrome, are often accompanied by skin lesions. In addition to celiac disease and dermatitis herpetiformis, the cutaneous manifestation of celiac disease, wheat sensitivity also includes nonceliac gluten sensitivity (NCGS), allergic nickel contact mucositis, wheat allergy, amylase-trypsin inhibitor intolerance, and fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) intolerance.

[Dermoscopy of inflammatory skin diseases].

The dermoscope was initially used in dermatology to distinguish between pigmented and nonpigmented tumors, both benign and malignant. Over the last two decades, however, the spectrum of dermoscopy has broadened and its role in the diagnosis of nonneoplastic diseases, in particular inflammatory skin diseases, has become increasingly important. In the diagnosis of general and inflammatory skin diseases, it is recommended that dermoscopic evaluation should be performed after clinical examination.

[Dermoscopy of genodermatoses].

Genodermatoses are a group of inherited skin diseases whose diagnosis is challenging due to their rarity as well as their clinical and genetic diversity. The majority of genodermatoses are autosomal or X‑linked inherited, but mosaic forms are also observed. Genodermatoses comprise various phenotypes ranging from limited cutaneous disease to severe cutaneous and extracutaneous involvement and may also be early warning signs of a multisystemic disorder.

[Dermoscopy of granulomatous and autoimmune skin diseases].

Dermoscopy is an easily accessible, noninvasive diagnostic tool, originally used in the differentiation of benign and malignant skin tumors. Other structures beside pigment content observed by dermoscopy, e.g.
