Onychomycosis is a fungal nail infection which has a considerable impact on the quality of life of patients. The aim of this study was to analyze onychomycosis cases with respect to fungal species, infection sites, and patient demographics such as age and sex. Furthermore, we assessed whether simple clinical and demographic data could predict positive results for mycological culture. A retrospective analysis of 2722 patients who had nail samples investigated with direct microscopy and mycological culture was performed. The fungi most frequently identified were Trichophyton rubrum in the toenails and Candida albicans in the fingernails, with a detailed incidence varying by age and sex. Predictive models, including logistic regression and k-nearest neighbors, did not provide clinically useful accuracy. Therefore, it is necessary to perform confirmatory diagnostics before starting antifungal treatment.

Introduction: Basal cell carcinoma (BCC) is the most common skin cancer with increasing prevalence in the last years. The most important risk factor for development of BCC is exposure to UV radiation. Surgical excision remains the first line treatment, but there are some non-surgical methods of treatment. The aim of this study is to present a case of 100-year-old patient with advanced BCC in temporal area who refused surgical treatment. The noninvasive treatment with imiquimod was successful., Case Presentation: The 100-year-old male patient was admitted to the dermatological outpatient clinic with an ulceration within the forehead, which had been increasing in size for 3 years. Physical examination revealed shallow irregular ulceration with erythematous pearly-shaped borders in the right temporal area measuring ca. 1.5 cm × 2 cm. Dermatoscopic examination of the lesion showed arborising vessels on the semitransparent background, white structureless area and numerous erosions, leading to an initial diagnosis of BCC. Patient refused any surgical interventions within the lesion including skin biopsy. Consequently, treatment with 5% imiquimod was initiated with cream application for 8 weeks, once daily 5 times a week. 8 months after termination of treatment there were no clinical and dermoscopic signs of recurrence of BCC. The patient remains under dermatological follow-up.

Background: Superficial fungal infections (SFI) are contagious conditions affecting the skin and its appendages, caused by various fungal species. Monitoring the distribution of common pathogens and identifying at-risk patient groups are essential for effective management and prevention., Objectives: This study investigates the characteristics of SFI in Poland's Malopolska region from 2017 to 2019, focusing on etiological agents, infection sites and risk factors., Patients/methods: A retrospective analysis was conducted on 4522 mycological cultures from 3594 patients, incorporating demographic data (age, sex), sample sites and mycological test results., Results: Among the 1175 positive mycological tests recorded from 959 patients, Trichophyton rubrum-primarily affecting toenails and feet-and Candida albicans-mainly targeting fingernails-were the most common pathogens across all age groups. Children exhibited a higher incidence of infections caused by Microsporum canis, Malassezia furfur and T. mentagrophytes. In contrast, Scopulariopsis brevicaulis was more frequently identified in individuals over 60 years old., Conclusions: The observed trends in SFI characteristics at our centre during the pre-pandemic period align with global epidemiological data. However, further studies are warranted to address existing gaps in understanding the epidemiology of SFI and to refine preventive and therapeutic strategies., (© 2024 Wiley‐VCH GmbH.

We report a case of a 75-year-old male with suspected onychomycosis of the right hand and both feet who also developed kerion-like changes in the skin of his head and neck after recent inguinal hernia surgery. A mycological examination revealed the presence of Trichophyton rubrum in all affected sites. Treatment with oral terbinafine and topical isoconazole nitrate was started, resulting in a significant improvement in skin lesions. The case we present underscores the possibility of autoinoculation transmission of dermatophytes and the need for a careful evaluation of the coexistence of mycoses at different anatomical sites., Competing Interests: There are none., (© 2024 The Author(s).)

Introduction: Psoriasis is a chronic inflammatory disease that negatively impacts patients' quality of life (QoL) and mental health. Itch and pain are prevalent symptoms of psoriasis and contribute to the psychosocial burden of this disease. This study aimed to evaluate the impact of skin pain on the prevalence and severity of symptoms of anxiety and depression and on the QoL in psoriasis patients. Methods: The studied population comprised 106 adults with psoriasis (34% female; mean age 42.1 ± 13.0 years). Disease severity was measured with the Psoriasis Area and Severity Index (PASI). The intensity of skin pain was assessed with the NRS and the Short Form McGill Pain Questionnaire (SF-MPQ). The Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) questionnaires were used to estimate the severity of depression and anxiety, respectively, as was the Hospital Anxiety and Depression Scale (HADS). Quality of life (QoL) was studied using the Dermatology Life Quality Index (DLQI). Results: Regarding anxiety assessment, females reported significantly higher scores with the HADS-A (8.42 ± 4.85 points vs. 5.14 ± 3.9 points; p < 0.001) and the GAD-7 compared to men (7.50 ± 5.58 points vs. 5.24 ± 4.79 points; p = 0.036). Similarly, the severity of depression was significantly higher in women, as measured with the PHQ-9 (7.50 ± 5.58 points vs. 5.24 ± 4.79 points, p = 0.021). Psoriasis patients with skin pain scored significantly higher in HADS Total score ( p = 0.043), HADS-A ( p = 0.022), PHQ-9 ( p = 0.035), and DLQI ( p < 0.001) than the rest of the studied group. The intensity of skin pain measured with the SF-MPQ correlated significantly with HADS Total score ( p = 0.021), HADS-A ( p < 0.001), HADS-D ( p = 0.038), and PHQ-9 ( p < 0.001). Additionally, there was a significant correlation between the intensity of cutaneous pain assessed using the VAS and the PHQ-9 ( p = 0.022). Conclusions: Skin pain significantly influences the well-being of patients with psoriasis as well as the symptoms of anxiety and depression. In particular, women with psoriasis are at increased risk of developing anxiety and depression. Our findings underline the necessity for a multidisciplinary approach to the management of this dermatosis.

Background: Psoriasis is a common inflammatory disease that is often associated with itch and pain. This study aimed to evaluate the clinical characteristics of skin pain among patients with psoriasis. Materials: A total of 106 patients diagnosed with psoriasis were included in the study (34% female; mean age 42.1 ± 13.0 years). Disease severity was assessed using the Psoriasis Area and Severity Index (PASI). Itch severity was evaluated using the numeric rating scale (NRS) and 4-Item Itch Score (4IIS). The intensity of skin pain was measured through the NRS, short-form McGill pain questionnaire (SF-MPQ), visual analog scale (VAS), and Douleur Neuropathique-4 questionnaire (DN4). Results: In the past week, 84.9% of psoriasis patients reported itch, while 50% of them reported skin pain. The average NRS for itch was 4.52 ± 2.88 points, and the 4IIS yielded a mean score of 6.79 ± 4.37 points. In terms of the intensity of cutaneous pain, the mean NRS was 2.42 ± 2.96 points; the SF-MPQ score averaged 4.84 ± 7.51 points; and the VAS score was 1.92 ± 2.65 points. Furthermore, 17% of adult psoriasis patients reported neuropathic pain. In 84.9% of the participants, skin pain was concurrent with areas affected by itch, while 18.9% of patients exhibited cutaneous pain encompassing all itchy areas. The pain NRS demonstrated significant correlations with the SF-MPQ (r = 0.531, p < 0.001), VAS (r = 0.779, p < 0.001), itch NRS (r = 0.551, p < 0.001), and 4IIS (r = 0.569, p < 0.001). No association was found between the pain NRS and PASI or disease duration. Conclusions: Skin pain of mild intensity and itch of moderate intensity are prevalent symptoms in psoriasis patients. Strong correlations between skin pain and itch can be explained by the process of neurogenic inflammation.

Infectious skin diseases constitute a significant public health problem. Despite the systematic development of many modern diagnostic and therapeutic tools, they still pose a serious challenge for clinicians. Due to their prevalence and mild course in most cases, they are often marginalized, which can delay their diagnosis and treatment initiation. Such an approach in more clinically advanced cases can have serious consequences, sometimes leading to tragic outcomes. This work presents a series of four cases of common infectious skin diseases with an unusually atypical clinical picture: the history of a 49-year-old female patient with recurrent erysipelas of the right lower leg co-occurring with a SARS-CoV-2 infection, a 75-year-old male patient with a generalized form of herpes zoster, a 38-year-old female patient with a complicated severe course of head lice, and a 34-year-old male patient with a severe form of post-steroid mycosis. In each of these cases, difficulties in making the correct diagnosis were highlighted, even though they represent some of the most common bacterial, viral, parasitic, and fungal dermatoses. The paper discusses the risk factors for these diseases, the pathophysiology of their atypical course, the effects and challenges in the therapeutic approach conducted. Infectious skin dermatoses require aggressive treatment and should never be underestimated.

Background and Objectives : 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. We aimed to evaluate endosomal TLR type 7, 8 and 9 as predictive biomarkers of HCQ efficacy. Materials and Methods : We conducted a case-control study comparing CLE patients retrospectively assigned to three subgroups based on 3-6-month Cutaneous LE Disease Area and Severity Index (CLASI) reduction upon treatment with HCQ (I = <40% vs. II = 40-80% vs. III = >80%). Before HCQ, lesional skin specimens were collected in untreated CLE and through immunohistochemistry; TLR-7, -8 and -9 expression was evaluated in the epidermis and the lymphocytic infiltrate was evaluated in the dermis. Results : Sixty-six lesional skin biopsies were compared with healthy controls. CLE patients displayed lower epidermal expression of total TLR 8 and 9 as well as infiltrating TLR-8, TLR9 + lymphocytes compared to controls. High HCQ responders differed from low responders for TLR-9 positivity (high vs. low) and for the lymphocytic dermal infiltrate (high vs. low). Conclusions : TLR9 could be envisaged as a possible biomarker to predict HCQ response level and dosage in CLE patients.

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. The aim of the study is to comprehensively assess the clinical characteristics of elderly patients (>60 years old) with AD. Data were collected from 26 AD patients treated in the Department of Dermatology of the University Hospital in Krakow. Late-onset AD with generalized/prurigo lesions was the most predominant phenotype. Skin biopsy was required in 15 (58%) patients in the differential diagnosis process. Allergic rhinitis, a positive family history of atopy and xerosis were associated with a higher number of hospitalizations during the year prior to the last admission (p = 0.034, p = 0.046 and p = 0.036, respectively). Xerosis was more prevalent among subjects with polypharmacy (p = 0.046) and higher serum total IgE concentration (p = 0.048). AD in elderly patients is a new phenotype of the disease that requires careful differential diagnosis. Aged patients with an individual or family history of atopy, due to the increased incidence of severe exacerbations of AD, may benefit from the introduction of proactive therapy.

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. A group of 150 adults suffering from AD treated with TCS during last year was asked to fill an anonymous questionnaire. The course of topical treatment was analyzed in the context of the severity of symptoms and the knowledge of the patients about therapy. During the last year, the majority of patients (66%) were treated with class IV TCS; however, in the last two weeks, class I TCS was used the most frequently (35%). Only 11% were familiar with the concept of intermittent therapy and 4% used the fingertip unit (FTU). In total, 77% of them used TCI. Most of the patients used the same class of TCS permanently. Unfortunately, patients are unaware of simple approaches (like intermittent therapy or FTU) that increase both the effectiveness and safety of the treatment. Practicians should be aware of these problems to identify and eliminate them, primarily through the education of patients.

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., Material and Methods: The study included 36 adult patients with severe and very severe AD and 20 healthy Caucasian volunteers. The severity of skin lesions was assessed by the EASI scale. Skin itch was evaluated by a visual-analogue scale (VAS), and sleep disorders were assessed by the Polish version of the Athens Insomnia Scale (AIS). Serum melatonin concentration of patients and controls was determined by ELISA., Results: Melatonin concentration in patients with very severe AD was significantly ( p < 0.001) lower than in patients with severe AD, however, melatonin concentration in the group of AD patients did not differ significantly ( p = 0.33) from that observed in the control group. There was a significant negative correlation between the concentration of melatonin in the study group and the severity of itching ( R = -0.54, p < 0.001). The intensity of sleep disorders was significantly higher ( p < 0.001) in patients with a very severe form of AD compared to patients with severe AD. Moreover, there was a significant negative correlation between melatonin concentration and sleep disorders ( R = -0.67, p < 0.001)., Conclusions: Our results clearly showed that sleep disturbances are more expressed in very severe AD patients compared to subjects suffering from severe disease. We also suggest that melatonin serum concentration could play a role in the pathogenesis of sleep disturbances in AD patients., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

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). Although the root cause of the disease was established in the mid-twentieth century, a detailed explanation of the processes leading to the development of symptoms has not yet been proposed. They include complex abnormalities at the molecular, metabolic, and immunological levels. Diagnostics is based primarily on the clinical presentation of the disease, while auxiliary tests play secondary role. The low prevalence of the disease, meaning that physicians are unfamiliar with its recognition, often leads to delays in diagnosis and appropriate treatment. The therapy is causal and based on administering niacinamide. Failure to implement treatment in the early stages of the disease leads to the patient's death. The aim of this literature review is to summarize the current state of knowledge on the pathomechanisms of pellagra, highlighting the clinical implications, and key elements of diagnostic and therapeutic management that are important in the treatment of pellagra patients.

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. Melatonin (MT), the indoleamine produced by pineal gland (but also by multiple other tissues, including skin), plays a pivotal role in maintaining the sleep/wake homeostasis. Additionally, it possesses strong antioxidant and anti-inflammatory properties, which might directly link chronic skin inflammation and sleep abnormalities characteristic of AD. The objective of this work is to systematically present and summarize the results of studies (both experimental and clinical) that investigated the role of MT in the AD, with a focus on the antioxidant and immunomodulatory effects of MT.

Atopic dermatitis (AD) is classified as a most common inflammatory skin disease. The condition is characterized by recurrent eczematous lesions and intense pruritus or itch, a hallmark of AD. The aim of this study was to identify the provoking factors of itch in severe AD adult patients. There were 34 adult patients suffering from AD of the median age of 40 years enrolled into the study and a control group that consisted of 20 healthy subjects. The severity of AD was assessed with the SCORing Atopic Dermatitis (SCORAD) index, pruritus intensity was assessed on a visual analog scale (VAS), and itch aggravating factors were assessed with a questionnaire. Specific IgE (sIgE) antibodies and interleukin IL-33 were measured in venous blood. We found that all the patients with severe AD had intensive itch (VAS: 9-10 points) during the whole day and 30 (88.2%) patients had it during nighttime. The most significant factors aggravating itch were the following: dry skin (27 patients; 79.4%), exposure to dust mite (22 patients; 64.7%,), and emotional distress (17 patients; 50%). Moreover, there was a positive correlation between the intensity of itch and the level of sIgE antibodies to dust mite (p < 0.001). The content of IL-33 was significantly higher in AD patients with severe skin lesions. This exploratory study shows that skin dryness, dust exposure, and distress play an essential role in the exacerbation of AD in the adult population.

Atopic dermatitis (AD) is characterized by chronic, relapsing, pruritic skin inflammation and does not have a well-understood pathogenesis. In this study, we addressed the contribution of adipokines to AD eczema based on the assessment of blood levels of adiponectin, resistin, leptin, lipocalin-2, and vaspin in adult non-obese patients suffering from chronic extrinsic childhood-onset AD. We investigated 49 AD patients with a median age of 37 years. The control group consisted of 30 age-matched healthy subjects. Adipokines were assessed in the serum by ELISA assays and the severity of AD with the SCORing Atopic Dermatitis (SCORAD) index. We found that adiponectin and resistin decreased and leptin appreciably increased in AD patients when compared to those in healthy subjects. Further, the levels of adiponectin and resistin were inversely related to the intensity of eczema. In conclusion, apart from the formerly investigated role of leptin in AD, this study points to adiponectin and resistin as the potential candidate adipokine biomarkers involved in shaping eczema intensity and severity, which may help predict disease exacerbations and enable the development of effective targeted therapeutic interventions.

Atopic dermatitis (AD) and chronic spontaneous urticaria (CSU) are common chronic and recurrent dermatoses. The role of vitamin D in the immunological processes, including the development of inflammation, has been the subject of numerous studies. The feasible measurement of vitamin D serum concentration and possibly supplementation necessitates the assessment of its impact on the clinical severity of mentioned diseases., Aim: The aim of the study was to determine the relationship between blood serum vitamin D concentration and the severity of clinical symptoms in the group of adults suffering from AD or CSU., Materials and Methods: The study was conducted in 2018 on groups of patients suffering from AD or CSU. Serum vitamin D concentration was determined by electrochemiluminescence assay. Student's t-test was adopted to compare vitamin D levels between groups. Spearman's rank correlation coefficient was used to assess the correlation between vitamin D concentration and the severity of AD (according to the SCORAD scale) and CSU (according to the UAS 7 scale)., Results: There was not found any statistically significant relationship between the severity of skin lesions scores in the course of AD and CSU and serum vitamin D concentration., (© 2020 MEDPRESS.)

Atopic dermatitis (AD - atopic eczema) is a chronic inflammatory dermatosis resulting from complex genetic, epigenetic and environmental interactions with an overlapping defect in the epidermal barrier.AD is one of the most common inflammatory dermatoses in children and adults., Aim: The aim of the study was to assess the relationship between serum basal tryptase (sBT) and total IgE (tIgE) level in blood serum and the severity of lesions (SCORAD; SCORing atopic dermatitis)., Materials and Methods: The study was performed in the group of adult patients (57 people, F/M: 30/27; average age: 37.5 years) and in the control group (10 people, K/M: 6/4; average age: 44 years). Diagnosis of atopic dermatitis was established by a dermatologist-allergist specialist based on the criteria of Hanifin and Rajka. The severity of lesions was determined on the SCORAD scale (SCORing atopic dermatitis)., Results: The distribution of tryptase concentration did not differ statistically significantly between patients with various disease severity and the control group also the severity of skin lesions was significantly higher (p<0.001) in patients whose tIgE level exceeded 3500 IU / ml. Conclusion. sBT did not prove to be a useful biomarker in assessing., Conclusions: sBT did not prove to be a useful biomarker in assessing severity of AD. The present study demonstrated that in the patients with atopic dermatitis the concentration of total IgE was correlated with severity of the disease symptoms., (© 2020 MEDPRESS.)

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the world. It is characterized by recurrent eczematous skin lesions, fluctuating course and chronic pruritus. Increasing evidence suggest that AD is more common in adults than previously thought. The disease is characterized by an impaired skin barrier, aberrant Th2-type cytokine production and intensive pruritus. Epithelial keratinocytes constitute the first physical, chemical and immunological barrier, classified as a part of the innate defense system. These keratinocytes secrete various factors, e.g. alarmins such as thymic stromal lymphopoietin (TSLP) and interleukin 25 (IL-25). Serum levels of substance P (SP) have been reported to be increased in patients with AD and correlated with itch intensity. Several previous studies reported a positive association between AD severity and house dust mites (HDM) sensitization. The aim of the study was to analyze IL-25, TSLP and SP concentrations in blood serum of adult patients with severe AD, depending on the degree of allergy to HDM. There were 31 adult AD patients enrolled into the study and a control group that consisted of 20 healthy subjects. AD was diagnosed on the basis of Hanifin and Rajka criteria. SCORing Atopic Dermatitis (SCORAD) and visual analogue (VAS) scores were used to assess the intensity of pruritus and blood content of specific IgE to HDM, as well as TSLP, IL-25 cytokines and SP was measured. Our study presents the evidence that IL-25 serum concentration is increased in patients with atopic dermatitis and this cytokine plays an important role in pathogenesis of this disease. HDM could stimulate the release of IL-25 which aggravates the disease severity. Our results corroborate previous findings on the role of TSLP in atopic dermatitis.

Atopic dermatitis is one of the most common inflammatory dermatoses in children and adults. To date, no clear relationship between the severity of AD and the exposure to dog and guinea pig-derived allergens has been established., Aim: The aim of the study was to assess the association between the specific serum immunoglobulin E levels (against dog and guinea pig) and the grade of skin symptoms measured with the SCORAD and VAS scales in the population of adult patients suffering from atopic dermatitis., Materials and Methods: The study was performed in the group of 47 patients suffering from atopic dermatitis since infancy (30 women and 17 men). Concentration of IgE was measured by the fluoroenzymatic immunoassay. The Mann-Whitney's test was used to compare the distribution of specific IgE concentration and the distribution of atopic dermatitis grade., Results: The statistically significant correlation between SCORAD and VAS scales, and the measured specific IgE concentrations for investigated fur animals was found., Conclusions: The study demonstrated that in the patients with atopic dermatitis the concentration of specific IgE was correlated with severity of the disease symptoms, including itch. This enables forecasting the course of the disease and selecting a group of patients who should immediately reduce their contact with allergen., (© 2020 MEDPRESS.)

Atopic dermatitis (AD) is a chronic skin disease with the etiology not yet conclusively established. Recent reports demonstrate the role of serotonin (5-hydroxytryptamine; 5-HT) in the pathogenesis of AD. The aim of this study was to investigate the relationship between the serum content of serotonin and depression in adult patients suffering from severe AD. There were 31 patients of the median age of 41 years enrolled into the study, who suffered from AD since childhood, and a control group that consisted of 14 healthy subjects. AD was diagnosed on the basis of Hanifin and Rajka criteria. The severity of skin lesions was assessed with the SCORing Atopic Dermatitis (SCORAD) index and that of depression with the Montgomery-Åsberg Depression Rating Scale (MADRS) questionnaire. We found that all of the patients with severe AD characterized by SCORAD >50 had depression. Depression was classified as mild and moderate according to the MADRS score. Serotonin content was significantly lower in the patients with severe AD (MADRS >12), and there was an adverse relation between the serotonin content and the score of depression, the features not noticed in the control group. We conclude that severe AD, as expressed by the intensification of skin lesions, associates with depression and with the lowering of serum serotonin content. The findings point attention to the cognitive and affective problems in AD patients which could worsen the course of the skin disease.

Atopic dermatitis (AD) is characterized by exacerbations and remissions of eczematous skin, underlain by impaired skin barrier and aberrant Th2-type and Th-22 cytokine production. A number of allergens, in particular contact with fur animals, may aggravate the disease. This study seeks to define the influence of having a regular contact with a pet cat at home on the severity of symptoms and signs of AD. We addressed the issue using the SCORing Atopic Dermatitis (SCORAD) and visual analog (VAS) scores to assess the intensity of pruritus and by measuring the blood content of specific IgE and IL-4, IL-13, and IL-22 cytokines. The study group consisted of 47 adult patients suffering from AD since childhood, 18 of whom declared having regular contact with a cat and the remaining 29 who denied it. There also was a control group consisted of 16 healthy volunteers with no AD signs. The SCORAD and VAS scores were significantly higher in patients in contact with a cat than in those without it (median SCORAD 61.0 vs. 50.4 and VAS 9.0 vs. 4.0 points, respectively). The sIgE of a majority of patients (94.4%) in contact with a cat was in Class V-VI, compared with just a few patients (3.4%) with no such contact, having sIgE in the same classes (p < 0.001). Significant correlations were revealed between SCORAD and VAS scores and the class level of serum sIgE value. In addition, IL-22 was a single elevated cytokine, only in the patients in contact with a cat, and it correlated with pruritus severity. The results of the study underline the need to beware of the cat fur allergen, and they stress forethought and caution in acquiring and keeping a pet cat by patients suffering from AD.

Atopic dermatitis is one of the most common inflammatory dermatoses in children and adults. The disorder is associated with significant worsening of quality of life. Due to the frequently suggested pathogenetic relationship with atopic dermatitis, immunoglobulin E seems to be an adequate indicator of the disease., Aim: The aim of the study was to assess the association between the total serum immunoglobulin E levels and the grade of skin lesions measured with the SCORAD and oSCORAD scales in the population of adult patients suffering from severe atopic dermatitis., Materials and Methods: The study was performed in the group of 31 patients suffering from atopic dermatitis since early childhood (17 women and 14 men) in 2017. Total IgE was measured by the fluoroenzymatic immunoassay. The Spearman's rank correlation coefficient was used to determine the power of the relationship between the concentration of total IgE and atopic dermatitis severity. The Kruskal-Wallis and Mann- Whitney's tests were used to compare the distribution of IgE concentration and the distribution of atopic dermatitis grade., Results: The statistically significant correlation between SCORAD/ oSCORAD and the measured IgE levels was found in the patients with the IgE level above 3500 IU/ml (19 subjects)., Conclusions: The present study demonstrated that in the patients with severe extrinsic atopic dermatitis, the concentration of total IgE was correlated with the severity of the disease. This suggests an opportunity of employing IgE as an atopic dermatitis biomarker., (© 2019 MEDPRESS.)

Introduction: Primary cutaneous lymphomas are lymphoproliferative skin infiltrates of T-, B- or NK-cells, classified according to the World Health Organization - European Organization of the Research and Treatment of Cancer (WHO-EORTC) criteria. They are the second most common group of extranodal non-Hodgkin lymphomas, that present in the skin with no evidence of systemic involvement at the time of diagnosis., Aims: The aim of the study was the analysis of clinical profile of cutaneous lymphomas in the tertiary referral center in Poland., Material and Methods: We analyzed case records of 63 patients (26 women, 37 men aged 19 - 86) referred to the Department of Dermatology, University Hospital in Cracow for the diagnosis and treatment of cutaneous lymphoma., Results: After analysis of clinical and histological data, the final diagnoses were: mycosis fungoides (42 patients), primary cutaneous CD30+ lymphoproliferative disorder (7), Sezary syndrome (3), parapsoriasis (3), primary cutaneous B-cell lymphoma (1), acute myeloid leukemia (1), Hodgkin lymphoma coexistent with mycosis fungoides (1), generalized allergic contact dermatitis (2) and erythema elevatum diutinum (1). We excluded 2 patients due to incomplete data. The most common location of skin lesions was the lower limb (52.46%) and most common clinical presentation was raised erythematous lesion (26.23%). Pruritus was present in 45.9% of the patients and 39.3% had extracutaneous symptoms, with lymphadenopathy as the most common symptom. 37.7% of patients presented with mild eosinophilia and another 37.7% with mild monocytosis. Prior to referral to our center, general practitioners misdiagnosed the lymphomas commonly as: atopic and contact dermatitis, borreliosis, drug-induced exanthema., Conclusions: The diagnosis of cutaneous lymphoma is often delayed due to their indolent, often recurring course, non-specific symptoms and uncommon appearance. The cooperation of a clinician and pathologist is essential in the diagnostic process.

Interleukin 10 (IL-10) is a potent anti-inflammatory cytokine. Increased production of IL-10 has been found in late syphilis, presumably creating favorable conditions for bacteria persistence. Single-nucleotide polymorphisms (SNPs) within the promoter of IL-10 gene have been found to influence IL-10 production. We investigated whether SNPs in the IL-10 gene promoter are associated with cerebrospinal fluid (CSF) levels of IL-10 and neurosyphilis. Polymorphisms in the gene for IL-10 (G→A mutation at the position -1084 and C→A mutation at the position -592) were sought in 35 patients with syphilis and 24 healthy volunteers. CSF examination (i.e. routine laboratory tests and IL-10 levels) was performed in all syphilis patients. Neurosyphilis was defined as reactive CSF VDRL test or CSF white blood cells⩾5/μL and CSF protein concentration⩾45mg/dL. Overall, 31% of patients with syphilis had neurosyphilis. CSF IL-10 levels were significantly higher in patients with neurosyphilis when compared to those with syphilis but not neurosyphilis. -1082 GG and -592 CC genotypes were significantly associated with higher CSF IL-10 levels. Moreover, these genotypes were found to be more frequent in individuals with neurosyphilis in comparison to those without neurosyphilis. Anti-inflammatory immune response seems to be important in pathogenesis of neurosyphilis. Our data suggest that host-related factors, such as SNPs of immune regulatory genes may influence the susceptibility to neurosyphilis., (Copyright © 2015 American Society for Histocompatibility and Immunogenetics.

Background: The mechanisms underlying the process of Treponema pallidum clearance from the central nervous system have not yet been established. Considering that neurosyphilis is associated with mild cerebrospinal fluid (CSF) pleocytosis with a lymphocytic predominance, it has been suggested that cells involved in the adaptive immune response may play a role in this process. In the current study, we assessed the cytokine production profile of T-helper cells in the serum and CSF of patients with early syphilis, with and without CSF abnormalities., Methods: Cerebrospinal fluid and blood samples were collected from 33 patients with secondary and early latent syphilis. Five patients (15%) had a reactive CSF Venereal Disease Research Laboratory test without any accompanying neurological symptoms. According to the Centers of Disease Control and Prevention classification, they were diagnosed with asymptomatic neurosyphilis. Serum and CSF levels of interferon-γ (IFN-γ; Th1-type cytokine), interleukin-4 (IL-4; Th2-type cytokine), and interleukin-17A (IL-17A; Th17-type cytokine) were determined by enzyme-linked immunosorbent assay., Results: Patients with asymptomatic neurosyphilis had significantly higher levels of IL-17A (8-fold) and IFN-γ (7.8-fold) in the CSF compared with patients in the no-neurosyphilis group. Six individuals had CSF pleocytosis but a negative CSF Venereal Disease Research Laboratory test result (presumptive neurosyphilis group). In this group, CSF IFN-γ and CSF IL-17A levels were also significantly elevated when compared with no-neurosyphilis group. There was no correlation between serum and CSF concentrations of IL-17A. However, CSF pleocytosis correlated positively with both CSF IL-17A (r = 0.4, P = 0.01) and IFN-γ (r = 0.42, P = 0.01)., Conclusions: Increased CSF levels of IFN-γ and IL-17A in syphilitic patients with CSF abnormalities suggest that cells of adaptive immunity (probably T-helper cells producing IFN-γ and IL-17) may contribute to the inflammatory response associated with neurosyphilis. In addition, the lack of correlation between serum and CSF IL-17A levels suggests intrathecal production of this cytokine. Further studies are needed to establish the exact nature of the immune response accompanying neurosyphilis and its clinical significance.

Background: Syphilis is caused by a spirochete Treponema pallidum. Invasion of the central nervous system (CNS) by T. pallidum may appear early during the course of disease. The diagnosis of confirmed neurosyphilis is based on the reactive Venereal Disease Research Laboratory (VDRL) in cerebrospinal fluid (CSF). Recent studies indicated that serum RPR ≥ 1:32 are associated with higher risk of reactivity of CSF VDRL., Aims: The main aim of the current study was to assess cerebrospinal fluid serological and biochemical abnormalities in HIV negative subjects with secondary and early latent syphilis and serum VDRL ≥ 1:32., Materials and Methods: Clinical and laboratory data of 33 HIV-negative patients with secondary and early latent syphilis, with the serum VDRL titer ≥ 1:32, who underwent a lumbar puncture and were treated in Department of Dermatology at Jagiellonian University School of Medicine in Cracow, were collected., Results: Clinical examination revealed no symptoms of CNS involvement in all patients. 18% (n = 6) of patients met the criteria of confirmed neurosyphilis (reactive CSF-VDRL). In 14 (42%) patients CSF WBC count ≥ 5/ul was found, and in 13 (39%) subjects there was elevated CSF protein concentration (≥ 45 mg/dL). 10 patients had CSF WBC count ≥ 5/ul and/or elevated CSF protein concentration (≥ 45 mg/dL) but CSF-VDRL was not reactive., Conclusions: Indications for CSF examination in HIV-negative patients with early syphilis are the subject of discussion. It seems that all patients with syphilis and with CSF abnormalities (reactive serological tests, elevated CSF WBC count, elevated protein concentration) should be treated according to protocols for neurosyphilis. But there is a need for identification of biomarkes in order to identify a group of patients with syphilis, in whom risk of such abnormalities is high.

Papulo- and vesiculo-necrotic lesions are rare manifestations of secondary syphilis. Until now it has been described only in HIV-infected patients with advanced stages of immunosuppression. This case report describes an unusual case of PLEVA-like syphilis in a 33-year-old man with newly diagnosed HIV infection. Despite that the CD4 cells level and viral load did not indicate the advance stage of immunosuppression, the unusual manifestation of syphilis and neurosyphilis occurred. The presented case indicates the need for HIV screening in every patient with syphilis especially when the clinical manifestation is unusual. Importance of syphilis testing in every case with atypical rashes should be also highlighted.

Background: Linear immunoglobulin A (IgA) bullous dermatosis (LABD) is a rare autoimmune blistering disorder. The disease may be either idiopathic or druginduced. Over the past 30 years, approximately one hundred LABD cases have been described as induced by a wide range of drugs, chiefly antibiotics., Main Observations: We report the case of 37-year-old woman who developed pruritic bullous lesions spread all over the body three weeks after her last dose of cefuroxime axetil. Antibiotic therapy was started due to rhino-sinusitis., Conclusions: In most reported cases of drug-induced LABD, skin lesions occur within the time of drug administration. However, the onset of disease may be even after discontinuation of treatment. It seems that in such cases, other clinical conditions (like infection) act, as cofactors of immunologic response.

Melatonin, a product of the pineal gland, is released from the gut mucosa in response to food ingestion. Specific receptors for melatonin have been detected in many gastrointestinal tissues including the pancreas. Melatonin as well as its precursor, L-tryptophan, attenuates the severity of acute pancreatitis and protects the pancreatic tissue from the damage caused by acute inflammation. The beneficial effect of melatonin on acute pancreatitis, which has been reported in many experimental studies and supported by clinical observations, is related to: (1) enhancement of antioxidant defense of the pancreatic tissue, through direct scavenging of toxic radical oxygen (ROS) and nitrogen (RNS) species, (2) preservation of the activity of antioxidant enzymes; such as superoxide dismutase (SOD), catalase (CAT), or glutathione peroxidase (GPx), (3) the decline of pro-inflammatory cytokine tumor necrosis α (TNFα) production, accompanied by stimulation of an anti-inflammatory IL-10, (4) improvement of pancreatic blood flow and decrease of neutrophil infiltration, (5) reduction of apoptosis and necrosis in the inflamed pancreatic tissue, (6) increased production of chaperon protein (HSP60), and (7) promotion of regenerative process in the pancreas. Conclusion. Endogenous melatonin produced from L-tryptophan could be one of the native mechanisms protecting the pancreas from acute damage and accelerating regeneration of this gland. The beneficial effects of melatonin shown in experimental studies suggest that melatonin ought to be employed in the clinical trials as a supportive therapy in acute pancreatitis and could be used in people at high risk for acute pancreatitis to prevent the development of pancreatic inflammation.

Melatonin, a pineal indoleamine, protects the pancreas against acute damage; however, the involvement of the pineal gland in the pancreatoprotective action of melatonin is unknown. The primary aim of this study was to determine the effects of pinealectomy on the course of acute caerulein-induced pancreatitis (AP) in rats. AP was induced by a subcutaneous infusion of caerulein (25 μg/kg) into pinealectomized or sham-operated animals. Melatonin (5 or 25 mg/kg) was given via intraperitoneal (ip) injection 30 min prior to the induction of AP. The pancreatic content of the lipid peroxidation products malondialdehyde and 4-hydroxynonenal (MDA + 4HNE) and the activity of an antioxidative enzyme, glutathione peroxidase (GSH-Px), were measured in each group of rats. Melatonin blood levels were measured by radioimmunoassay (RIA). In the sham-operated rats, AP was confirmed with histological examination and manifested as pancreatic edema and an increase in the blood lipase level (by 1,500%). In addition, the pancreatic content of MDA+ 4HNE was increased by 200%, and pancreatic glutathione peroxydase (GSH-Px) activity was reduced by 40%. Pinealectomy significantly aggravated the histological manifestations of AP, reduced the GSH-Px activity and markedly augmented the levels of MDA+ 4HNE in the pancreas of rats with or without AP as compared to sham-operated animals. Melatonin was undetectable in the blood of the pinealectomized rats with or without AP. Treatment with melatonin (25 mg/kg, ip) prevented the development of AP in the sham-operated rats and significantly reduced pancreatic inflammation in the animals previously subjected to pinealectomy. In conclusion, pineal melatonin contributes to the pancreatic protection through the activation of the antioxidative defense mechanism in pancreatic tissue as well as its direct antioxidant effects.

Introduction: Coronary artery bypass graft (CABG) surgery is associated with systemic response and increased concentrations of numerous cytokines. Vascular endothelial growth factor (VEGF) related pathway also seems to be involved in inflammatory response induced by CABG., Objectives: The aim of this study was to analyze the association between the VEGF gene +405 G>C polymorphism (linked to serum VEGF production), and the short-term clinical outcome during the in-hospital period (30 days) in patients undergoing CABG., Patients and Methods: Genotyping for VEGF gene +405 G>C polymorphism was performed in 64 patients with coronary artery disease at a mean age of 66 years (76.6% males), with a mean EuroSCORE (European System for Cardiac Operative Risk Evaluation) of 2.5 (0-2 points: 50% patients, 3-4: 25%, > or =5 points: 25%), who underwent CABG surgery., Results: Twenty-one (33%) patients were homozygous for the +405 G allele, 40 (63%) were heterozygous, and 3 were homozygous for the +405 C allele. Ten patients died during the 30-day follow-up (7 subjects with +405 GG genotype, and the other 3 carriers of the +405 C allele). Using multivariate logistic regression analysis, the risk of death after CABG was increased in patients with +405 GG genotype (odds ratio [OR] = 6.7; 95% confidence interval [CI] 1.5-29.4) and with EuroSCORE > or =5 points (OR = 4.4; 95% CI 1.1-18.1)., Conclusions: The VEGF gene +405 G>C polymorphism might be a prognostic factor of an adverse postoperative course in patients undergoing CABG surgery. Apart from its proangiogenic action, VEGF may have additional, possibly proinflammatory properties.

Rosacea is a chronic, inflammatory skin disease which is mainly localized in the central region of the face. Papules and pustules appear on the erythematic ground. Rosacea is common in population. Four subtypes of rosacea (erythematoteleangiectatic rosacea, ETR; papulo - pustular rosacea, PPR; ocular rosacea and phymatous rosacea) are classified (according to current classification) and one variant rosacea (granulomatous rosacea, GR). It is considered that an attempt to determine of triggering factors of rosacea should be the first step to treatment. Then it should be tried to eliminate contact with them. The aim of this study was an analysis of triggering factors of rosacea. 43 women and 26 men treated in the Dermatology Outpatient's Clinic of Jagiellonian University School of Medicine in Cracow were enrolled in the study. All patients were asked which factors trigger skin changes according to them. Patients mentioned most often: stress (58 percent), sun exposure (56.5 per. cent), alcohol (33.3 percent), exercise (29 percent), drinking coffee (21.7 percent) and hot meals (20.3 percent). They regarded the sun as the most strongly aggravating factor of rosacea (29.2 percent). It seems, that elimination and reduction of contact with aggravating factors is still an undervalued aspect of rosacea's treatment. Patients' motivation for use of prevention seems to be also very important. Knowledge about aggravating factors of rosacea, coming directly from patients' observations, may help in more effective treatment.

Object: we studied erysipelas by conducting a retrospective analysis of 319 patients with erysipelas treated in Dermatology Department Jagiellonian University in Krakow between 1994 and 2004., Methods: we performed a retrospective analysis of 319 patients hospitalized for erysipelas in our institution during a 10 year period. The statistical significance was examined by chi square and Kruskal-Wallis test (significant value p< or =0.05)., Results: there were 35% males and 65% females patients. Median age was 63 years. Most of the female patients were pensioners (32.7%), most of the male patients were physical workers (40.5%). Summer time was the most frequent season for hospitalization (32.3%), and winter time was the rarest (17%). Most of the erysipelas has involved the lower limb (59.2%). There was significant dependence between the regional risk factors and occupation. The recurrent cases occurred in 67.3% cases with lower limb localisation in 69.44% cases. The most rare recurrent cases found on upper limb (6%). The systemic risk factors were associated with recurrent erysipelas in 69.44%. Complications, such as abscess formation, lymphangitis, venous insufficiency, osteitis, arthritis, septic tendonitis and elephantiasis were found in 25%., Conclusions: after review of the literature and our experiences it is clear that there is a strong need for interdisciplinary treatment to avoid various potential complications of erysipelas.

The so-called sexually transmitted diseases (STD) are the ones in which the transmission of pathogenic factors is mostly caused by sexual intercourse. Every year 333 million of documented new cases of STD occur all over the world. Due to an increase of incidence of STD, which was observed in the Province of Małopolska, the authors decided to check the knowledge of basic clinical symptoms and risk factors of transmission of venereal diseases. A group of 104 soldiers (quartered in military bases in Cracow) and a group of 41 medical students (the 1st and the 2nd year of medical studies at the CMUJ in Cracow) were included in the analysis. The investigated population was exclusively consisting of men, aged 19-25. The authors used their own questionnaire consisting of 25 multiple-choice questions. The result of the research revealed a very poor knowledge of basic clinical symptoms and risk factors of STD in both analysed groups. It implies the necessity of conducting educational activities on prophylaxis, risk factors and symptomatology of venereal diseases.

Onychophagy is classified to the nail diseases caused by repeated injures. Nail-biting as autodestruction and onychophagy in its most aggressive form, is common not only among children but adults as well. Nail-biting in children belongs to the group of habits and habitual function, which allowed for relieving the anxiety, loneliness, inactivity in children deprived of safety feeling, love and nearest relationship. In most adults suffering from onychophagy psychiatric diseases are not diagnosed. There are different clinical symptoms of onychophagy depended on the degree and the way of performed injures. In this study we are promoting the multidisciplinary approach to the therapy of habitual nail-biting.
