Treatment with oral terbinafine and topical isoconazole nitrate was started, resulting in a significant improvement in skin lesions.

Cutaneous Toll-like Receptor 9 Pre-Defines Hydroxychloroquine Dosage in Patients with Both Discoid and Subacute Lupus Erythematosus.

: Cutaneous lupus erythematosus (CLE) presents clinically heterogeneous manifestations, partially explained by the different expression of Toll-like receptors (TLRs) type 8 and 9, located to endosomal compartments where they are poised to recognize microbial nucleic acids. This disease is empirically treated with hydroxychloroquine (HCQ), which is hallmarked with a safe and effective profile, but induces a slow and sometimes clinically insufficient therapeutic response. Currently, no biomarkers predictive of response are validated or even proposed in the scientific literature.

Clinical characteristics of elderly patients with atopic dermatitis - a retrospective observational study.

Atopic dermatitis (AD) is a chronic, recurrent inflammatory dermatosis. The most characteristic symptoms of the disease include itch, eczematous eruptions and excessive dryness of the skin. Elderly patients with AD represent a poorly characterized population because the physiological ageing, possible comorbidity and polypharmacy modify the clinical presentation typically observed in the younger age groups.

Clinical aspects of the treatment of atopic dermatitis with topical glucocorticoids and calcineurin inhibitors - a pilot questionnaire study.

Atopic dermatitis (AD) is the most common inflammatory skin disease. However, recent reports concerning the simple clinical aspects of treatment with topical glucocorticosteroids (TCS) and calcineurin inhibitors (TCI) are lacking. The objective of this study is providing an update on these characteristics of AD management.

The role of and gene polymorphisms in female androgenetic alopecia in the Polish population.

Introduction: Androgenetic alopecia is the most common type of non-cicatricial alopecia both in male and female patients. The mechanism that leads to hair loss is similar in both sexes, but the underlying cause, and especially the role of genes and sex hormones in the pathogenesis of the disease in women has not fully been explained as of yet. So far, a few attempts have been made to assess selected SNPs for and genes, but their results are not unequivocal and fully reproducible.

Scalp vascularization as a marker of topical minoxidil treatment efficacy in patients with androgenetic alopecia.

Introduction: Androgenetic alopecia is the most common type of non-cicatricial hair loss both in male and female patients. The pathomechanism of the disease involves chronic and progressive miniaturization of hair follicles, which leads to the conversion of terminal hair to vellus hair. Minoxidil is a first-line drug in the treatment of female pattern hair loss (FPHL).

Dendritic cells may help differentiate discoid lupus erythematosus alopecia from lichen planopilaris.

Introduction: Primary cicatricial alopecia (PCA) encompasses a heterogeneous group of inflammatory diseases characterized by the replacement of hair follicle structures by fibrous tissue. Discoid lupus erythematosus (DLE) and lichen planopilaris (LPP) are the most common causes of scarring alopecia. The distinction between both entities is often challenging because of significant clinical and histopathological overlap.

Dermoscopic features causing confusion between melanoma and benign nevi in clinical diagnosis - case series.

Unlabelled: The vast majority of melanoma lesions show typical dermoscopic features such as the presence of atypical pigmented network, the variety of colors within nevi, the asymmetry of structures and the presence of structureless areas. The clinical appearance of melanocytic lesions evolving over time also constitutes a clue to discover their malignant potential. Albeit there are some cases that do not exhibit typical dermoscopic and clinical findings suggesting their malignant potential.

Pathophysiology and clinical management of pellagra - a review.

Pellagra is a rare disease caused by niacin deficiency or a disruption of its metabolism. Its manifestations are dermatitis with pronounced photosensitivity, gastrointestinal symptoms, and neuropsychiatric ailments. Currently pellagra is developed in people who chronically abuse alcohol or are treated with medications from specific pharmacological groups (immunosuppressive and anti-tuberculosis drugs).

The role of family history and its influence on the onset time in female pattern hair loss.

Introduction: Female pattern hair loss (FPHL) is one of the most common causes of hair loss in women. Genetics plays an important role in the development of the disease, but the etiopathogenesis and the inheritance pattern in women remain unexplained.

Aim: To determine the extent to which FPHL is of genetic origin in women from the Polish population and whether a positive family history is a risk factor for its earlier onset.

Melatonin and sleep disorders in patients with severe atopic dermatitis.

Introduction: Many atopic dermatitis (AD) patients suffer from insomnia. Out of numerous factors associated with sleep disorders, melatonin seems to play a significant role.

Aim: To assess the relation between melatonin concentration and sleep disorders in adult patients with severe and very severe AD.

Molecular Proof of a Clinical Concept: Expression of Estrogen Alpha-, Beta-Receptors and G Protein-Coupled Estrogen Receptor 1 (GPER) in Histologically Assessed Common Nevi, Dysplastic Nevi and Melanomas.

Epidemiologic data show significant differences in melanoma incidence and outcomes between sexes. The role of hormonal receptors in the pathogenesis of melanocytic lesions remains unclear, thus we performed this study aiming to assess estrogen receptors expression in different melanocytic lesions. We performed a cross-sectional study that included 73 consecutively excised melanocytic lesions.

Allergic contact dermatitis to metal allergens in the South of Poland between 2008-2018.

Unlabelled: Allergic contact dermatitis (ACD) is a common skin disorder caused by contact with an exogenous substance that elicits a hypersensitivity response in susceptible individuals. Changing fashion trends, the process of industrialization as well as official legislations restricting the use of metals in recreational and occupational products change the epidemiological patterns in the European countries.

Aim: The aim of the study was to estimate the current prevalence of isolated and concurrent sensitization to nickel sulfate, cobalt chloride and potassium dichromate, as well as to investigate their associations with potentially predisposing epidemiological and clinical factors.

The Role of Bradykinin Receptors in the Etiopathogenesis of Chronic Spontaneous Urticaria.

Chronic spontaneous urticaria (CSU) is a distressing skin condition, which manifests as red, swollen, itchy, and sometimes painful hives or wheals appearing on skin. Recently, CSU has been associated with bradykinin release, which was previously discovered to be the main trigger of hereditary angioedema attacks. To study the role of bradykinin receptors 1 (BR1) and 2 (BR2) in the etiopathogenesis of CSU.

Predictive value of global dermoscopic pattern in patients diagnosed with cutaneous melanoma.

Introduction: Dermoscopy is one of the most commonly used methods in early diagnosis of melanoma. It is conducted to differentiate between benign and malignant patterns in melanocytic lesions.

Aim: To determine if there is a predominance of one dermoscopic pattern in patients with melanoma and if there is a significant difference in dominant global dermoscopic pattern in patients with cutaneous melanomas correlated with patients' sex and the location of the primary tumor.

Melatonin as an Antioxidant and Immunomodulator in Atopic Dermatitis-A New Look on an Old Story: A Review.

Atopic dermatitis (AD) is common inflammatory dermatosis, typically with chronic and recurrent course, which significantly reduces the quality of life. Sleep disturbances are considered to be remarkably burdensome ailments in patients with AD, and are routinely included during assessment of disease severity. Therefore, endogenous substances engaged in the control of circadian rhythms might be important in pathogenesis of AD and, possibly, be used as biomarkers of disease severity or even in development of novel therapies.

Metabolic Disorders/Obesity Is a Primary Risk Factor in Hidradenitis Suppurativa: An Immunohistochemical Real-World Approach.

Background: Hidradenitis suppurativa (HS) is an inflammatory, potentially scarring disease of the hair follicle, affecting the apocrine gland-bearing skin areas. The major comorbid disorders associated with the occurrence or the aggravation of the disease are obesity and smoking. Numerous efforts to dissociate these factors led to controversial results.

Hydroxychloroquine does not impair antibody response to 13-valent pneumococcal conjugate vaccine in patients with cutaneous lupus erythematosus-A pilot study.

Pneumococcal pneumonia is an important cause of morbidity and mortality among patients with lupus erythematosus. Therefore, a vaccination against pneumococcal infections prior to the immunosuppressive therapy is strongly recommended in these patients. Antimalarials are the standard first-line systemic therapy for cutaneous lupus erythematosus (CLE).
