RESUMEN
Acne fulminans (AF), a severe acne variant primarily evident in adolescent males, is characterized by the sudden onset of severe and often ulcerating acne with fever and polyarthritis. A case of a 14-year-old initially treated with clindamycin and surgical debridement, highlights the complexity of AF, including challenges in diagnosis, treatment, and the importance of early dermatological consultation. Successful management was achieved through systemic therapy with retinoids and corticosteroids, resulting in significant improvement. This case underscores the necessity of a coordinated effort among dermatologists, endocrinologists, and rheumatologists for effective AF treatment, illustrating the critical role of timely diagnosis and comprehensive care in managing this rare and challenging condition.
RESUMEN
BACKGROUND: Although non-invasive diagnostic methods are widely used to examine the nail apparatus (NA), studies in healthy ones are scarce, and analyzes were often conducted in small groups. In the literature, there are only a few reports on TOWL measurements. The results of TEWL studies in the proximal nailfold have not been published so far. MATERIALS AND METHODS: Based on a detailed interview and physical examination, 81 volunteers (40 women and 41 men) aged from 22 to 65 years were qualified for the study. In this study, the overall examination of the NA in relation to water loss was performed for the first time, regarding the hand (d, dominant; n, non-dominant) and finger types (number, start of count from thumbs) as well as sex and age. RESULTS: The average TEWL value in the entire group ranged from 7.53 c.u. in the finger nd4 to 11.09 c.u. in nd1. Both in the dominant and non-dominant hand, in the entire analyzed group, and taking into account gender, weak statistically significant relationships were observed between the finger type value and TEWL (p < 0.05).The TEWL values were lower moving away from the thumb, The average TOWL value in the entire group ranged from 5.01 c.u. in d1 to 7.34 c.u. in d5. Both in the dominant and non-dominant hand, in the entire analyzed group and considering gender, statistically significant relationships were observed between the type of finger and TOWL values (p < 0.05). The TOWL values were higher moving away from the thumb. Subsequently, the values of TOWL and TEWL did not depend on type of hand (dominant or non-dominant), sex and age. Weak and moderate statistically significant correlations were found between TEWL and TOWL values in the entire study group and in females, as well as in selected fingers in males (d2, nd2, d3, nd3, d5, nd5) (p < 0.05, r < 0.27). CONCLUSION: Non-invasive diagnostics such TEWL and TOWL measurements are useful to assess differences in structure and function between types of fingers. However, obtained results demand further studies.

Nonmelanocytic skin cancers (NMSCs) are currently the most common group of human cancers and include all tumors that are not melanomas. Increased exposure to sunlight over the past few years, the lack of regular and proper use of sunscreen, the aging of the population, and better screening techniques are the reasons for the escalation in their diagnosis. Squamous cell carcinoma (SCC) comprises nearly 37% of the tumors in this group and can originate from actinic keratosis (AK), which usually presents as pink, often scaly plaques, usually located on the face or scalp. Advances in dermatoscopy, as well as the development of other non-invasive skin imaging modalities such as high-frequency ultrasound (HFUS), reflectance confocal microscopy (RCM), and optical coherence tomography (OCT), have allowed for greatly increased sensitivity in diagnosing these lesions and monitoring their treatment. Since AK therapy is usually local, and SCCs must be removed surgically, non-invasive imaging methods enable to correctly qualify difficult lesions. This is especially important given that they are very often located on the face, and achieving an appropriate cosmetic result after treatments in this area is very important for the patients. In this review, the authors describe the use of non-invasive skin imaging methods in the diagnosis of actinic keratosis.

Hair dyeing is widely performed around the world. Chemical and thermal burns can result from the components present in brightening and coloring products, as well as the application process. We present a case of a chemical burn after applying hair dye and review the literature on similar cases, the composition of hair dyes, their mechanism of action, and the process of burns. The patient was a 17-year-old girl, who presented to the Dermatology Clinic with a 13 × 10 cm ulcer on the scalp after hair dyeing in a hairdressing salon. General and local treatment was applied, with particular emphasis on specialized dressings. The ulcer site was replaced by an area of scarring after 11 months of treatment. Based on the presented case and the review of the literature, we conclude that hair dye treatments warrant careful attention for potential scalp complications. The diagnostic and therapeutic approach demands a multidisciplinary effort, with ongoing patient-doctor cooperation throughout the treatment, which may complicate and span several months.
RESUMEN
Acne vulgaris is a common disease, which occurs in adolescents as well as adults and has a significant influence on the patient's quality of life (QoL) in every aspect. Due to resistance to standard therapies, it has become necessary to prospect for new treatment strategies. It is important to highlight that the diagnosis and treatment of the underlying cause of acne such as metabolic and hormonal disorders may significantly improve the effectiveness of acne treatment. The correlation between Insulin Resistance (IR) and acne has been proven. Both disorders share many common occurrence factors and activation pathways. Metformin, an antihyperglycemic agent, seems to be a possible therapy option, not only because of its insulin sensitizing ability but also via plenty of additional effects of this medicine. While the efficiency of metformin therapy in patients with acne and Polycystic Ovary Syndrome (PCOS) is well explored, it is still necessary to evaluate it in patients without any endocrinopathies. This meta-analysis aimed to estimate the effectiveness of oral metformin as a monotherapy in acne patients without PCOS or other endocrinopathies. Study selection was performed with included criteria such as no PCOS and other endocrinopathies diagnosed, oral administration of metformin, and metformin in monotherapy. Selected studies contained comparisons in the Global Acne Grading System (GAGS) before and after metformin therapy. Statistical analysis detected significant improvement in skin condition after treatment with metformin.
RESUMEN
Afamelanotide is a synthetic alpha melanocyte stimulating hormone presenting a higher activity than natural hormones. Its main properties are related to the enhanced production of eumelanin by agonistically binding to the melanocortin-1 receptor. Since 2016 afamelanotide has been especially applied to treat cases of erythropoietic porphyria (EPP), where painful photosensitivity has been observed since early childhood. The positive effect of afamelanotide in EPP administered subcutaneously improved tolerance to artificial white light and increased pain-free time spent in direct sunlight. In this review we summarize the possible use of afamelanotide in dermatology, with special emphasis on EPP and encourage including afamelanotide as a treatment option in patient care.

Teledermatology is a dynamically developing field of medicine with the potential to significantly impact the future functioning of the healthcare system, including the prevention, diagnostics, and treatment of sexually transmitted infections (STIs). While its implementation has resolved numerous issues associated with the traditional patient management model for STIs, the risk associated with handling sensitive patient data in a virtual space must not be overlooked. This article presents a literature review regarding the application of teledermatology in the diagnostics and treatment of STIs, with a particular focus on addressing relevant problems, potential obstacles, and examining the impact of the COVID-19 global epidemic on the development of this field.
RESUMEN
(1) Autoimmune thyroiditis (AIT) is the most common cause of primary hypothyroidism and one of the most frequent organ-specific autoimmune diseases. Its pathogenesis is polygenic and still requires further research. The aim of the study was to assess, for the first time in the Caucasian population, the role of selected TPO gene promoter polymorphisms (rs2071399 G/A, rs2071400C/T, rs2071402 A/G, and rs2071403 A/G) in the development of AIT. A total of 237 patients diagnosed with AIT and 130 healthy controls were genotyped for four TPO gene polymorphisms, and the results were statistically analyzed to check for the role of these polymorphisms. There were no significant differences in the genotype and allele frequencies of the studied TPO gene promoter polymorphisms between patients and controls (p > 0.05). The haplotype distribution (rs2071400-rs2071402-rs2071403) between the two studied groups was similar for the most common variants (CGA, CAG, TGG). Only a rare haplotype (CGG) occurred more frequently among patients compared to controls (p = 0.04). The studied TPO gene promoter polymorphisms did not show an association with susceptibility to AIT in the Caucasian Polish population, contrary to the results in Japanese patients.

Morphea en coup de sabre and progressive hemifacial atrophy are extremely rare connective tissue disorders causing facial deformity. In extreme cases, morphological disorders are accompanied by symptoms of a clear impairment of the stomatognathic system. The aetiology of the above-mentioned diseases is still unknown. Properly planned therapy in the field of maxillofacial orthopaedics makes it possible to correct the asymmetric pattern of hard tissue growth and thus enable rehabilitation. The task of augmentation techniques is the volumetric supplementation of tissue defects resulting from atrophic processes. The degree of destruction and the extent of changes determine the method of correction. Mild and moderate defects are treated mainly with biomaterials and autologous adipose tissue. The severe course of hemifacial atrophy and morphea en coup de sabre and the associated significant tissue atrophy necessitate the search for more complex methods of treatment. In this paper, we summarize the disturbances of the stomatognathic system in patients with craniofacial morphea, together with an analysis of current treatment options.
RESUMEN
AIMS/HYPOTHESIS: The study aimed to assess the usefulness of capillaroscopy and photoplethysmography in the search for early vascular anomalies in children with type 1 diabetes. METHODS: One hundred sixty children and adolescents aged 6-18, 125 patients with type 1 diabetes, and 35 healthy volunteers were enrolled in the study. We performed a detailed clinical evaluation, anthropometric measurements, nailfold capillaroscopy, and photoplethysmography. RESULTS: Patients with diabetes had more often abnormal morphology in capillaroscopy (68.60%, p = 0.019), enlarged capillaries (32.6%, p = 0.006), and more often more over five meandering capillaries (20.90%, p = 0.026) compared to healthy controls. Meandering capillaries correlated with higher parameters of nutritional status. In a photoplethysmography, patients with diagnosed neuropathy had a higher percentage of flow disturbance curves (p < 0.001) with a reduced frequency of normal curves (p = 0.050). CONCLUSIONS: Capillaroscopic and photoplethysmographic examinations are non-invasive, painless, fast, and inexpensive. They are devoid of side effects, and there are no limitations in the frequency of their use and repetition. The usefulness of capillaroscopy and photoplethysmography in the study of microcirculation in diabetic patients indicates the vast application possibilities of these methods in clinical practice.

Lipomas are usually sporadic, asymptomatic lesions, and their clinical and histologic presentation does not pose diagnostic difficulties. In ambiguous cases, however, knowledge of genetics is necessary. HMGA2 expression in adipose cells enables the differentiation of normal adipose tissue from lipoma and liposarcoma. Moreover, lipomas can be associated with genetic diseases, such as multiple endocrine neoplasia type 1, neurofibromatosis type 1, Wilson's disease, or mitochondrial diseases. Lipomas can run in families (familial multiple lipomatosis) or be a part of genetic syndromes such as PTEN hamartoma tumor syndrome, Proteus syndrome, and Pai syndrome. This study aims to present the genetic basis of lipomas and diseases in which these lesions occur in the clinical picture.
RESUMEN
Introduction: Acne vulgaris is one of the most common dermatological diseases. Hormonal imbalance affects the skin condition and results in the formation of acne vulgaris lesions. Aim: To evaluate serum levels of testosterone, prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), triglycerides (TG), and high-density lipoprotein (HDL) in patients with acne vulgaris and compare them to healthy population. Material and methods: Forty-one patients with acne vulgaris and 47 age- and body mass index (BMI)-matched controls were enrolled in the study. Results: The mean ± SD testosterone serum level in the study group was 0.45 ±1.03 ng/ml in females and 4.24 ±0.68 in males and in the control group 0.73 ±2.03 ng/ml and 5.3 ±1.3 ng/ml in females and males, respectively. The prolactin serum level was 16.73 ±8.02 ng/ml in the study group and in the control group 13.74 ±8.71 ng/ml (p = 0.011). The FSH serum level was 12.17 ±16.93 mIU/ml and 6.2 ±7.3 mIU/ml in the study and control groups, respectively (p = 0.0001), whereas LH serum levels were 18.44 ±19.71 mIU/ml and 11.26 ±8 mIU/ml, respectively (p = 0.2659). The HDL serum level was 65.63 ±15.67 mg/dl in the study group and 61.53 ±15.89 mg/dl in the control group (p = 0.219), and TG levels were 175.29 ±82.15 mg/dl and 87.32 ±30.64 mg/dl, respectively (p < 0.00001). Conclusions: Our study demonstrates, that hormonal and lipid imbalance could be linked to acne vulgaris formation. Evaluation of hormonal and lipid abnormalities could help in treatment decisions and could affect the occurrence of complications and the course of acne.
RESUMEN
Tertiary syphilis is a large diagnostic challenge. It is rarely the case that it affects the skin, bone tissue and the eyes at the same time. The presented case shows that extensive symptomatology of syphilis poses a challenge in making a proper diagnosis in patients whose history does not suspect STDs. The study aims to present the case of a young woman hospitalized with a suspected autoimmune disease, diagnosed with symptomatic late syphilis with involvement of the skin, bones and eyes.

Introduction: Psoriasis is one of the most common dermatological diseases. It is characterized by a chronic course with periods of exacerbations and remissions. The recurrent nature of the disease and the influence of environmental factors on its course require the patients not only to be treated but also to have knowledge of prophylaxis and proper skin care. Aim: Obtaining information on the level of knowledge of patients suffering from psoriasis in the field of triggering factors and proper skin care. Material and methods: A total of 130 patients with psoriasis participated in the study. The research tool was the author's questionnaire addressed to patients. Results: Research has shown that the main source of knowledge for people with psoriasis was the Internet (85%). Only 17% obtained information about the disease from medical personnel. The respondents were aware of the negative impact of only some environmental factors, such as: injuries (63%), stimulants (77%), stress (95%), and infections (69%). Most subjects attributed the therapeutic effect to brine baths (74%). Usually the patients were aware of the oiling (85%) and moisturizing (33%) effects of emollients on psoriatic lesions. Only 46% of the respondents obtained a positive test result. Demographic variables correlated with the level of knowledge. Conclusions: The knowledge of psoriasis patients about exacerbating factors and proper skin care is insufficient.
RESUMEN
Introduction: Demodex mites are common human ectoparasites found across a broad geographical range. They reside in pilosebaceous units of the skin and feed on sebum, epithelial and glandular cells. D. folliculorum is the more common mite, inhabiting the upper end of the pilosebaceous unit while D. brevis resides deeper in the skin and meibomian glands. Until now, Demodex mites have been obtained by various techniques such as skin scraping, cellophane tape, plucking eyelashes, and also by invasive biopsies. Aim: To assess whether non-invasively collected sebum samples of patients suspected of rosacea or demodicosis are suitable for NGS DNA Demodex analysis. Material and methods: Suspicion of seborrheic dermatitis or rosacea was the inclusion criterion. The study group consisted of 20 males, 1 female, age: 33-83, median: 58. Nasal dorsum was moisturized and an adhesive strip was applied. DNA was isolated from the sebum and sequenced with the use of MiSeq® Reagent Kit v2 and MiSeq® System. Results: Out of 7 patients who were positive by microscopy, 6 were found positive by NGS. Additional 4 patients were found positive only by NGS, adding to a total of ten. The NGS approach showed superior sensitivity compared to light microscopy (63% and 44%, respectively). In 3 patients, both Demodex species were identified by NGS. Conclusions: We believe to have proven that it is possible to study Demodex mites by NGS with sebum as the input sample. Furthermore, it is possible to identify and distinguish Demodex folliculorum from D. brevis in individual patients.
RESUMEN
Introduction: Trichoscopy allows us to distinguish between different types of alopecia and to determine the stage of the disease. High-frequency ultrasonography (HF-USG) enables the evaluation of structures that are not available for clinical and trichoscopic examination, but it has not been widely used to date in the evaluation of patients with alopecia areata (AA) and other scalp disorders. Aim: To characterise the ultrasound images of patients with AA, including different stages of the disease, and to compare them with trichoscopic images and other scalp diseases. Material and methods: Twenty-five patients with AA, on the basis of trichoscopic examination, were qualified to three groups: with active, inactive, and regrowth phase. Next, HF-USG (20 MHz) with qualitative and quantitative evaluation of various elements of the images was performed: entrance echo (EE), dermis (dermal background; DB), follicular structures (FS), dermal/ subdermal border (D/SB). The results were compared with 10 healthy volunteers, 10 patients with androgenic alopecia (AGA), and 12 with seborrhoeic dermatitis (SebD). Results: Active AA was characterised by FS with distinct borders, drop-like shaped, with a widened distal end located in the lower layers of DB. Inactive AA was characterised by a smaller number of FS without distinct borders. In the regrowth phase, FS of different widths, elongated, and with widened distal parts located at different DB depths were observed. Conclusions: HF-USG (20 MHz) may be a valuable diagnostic method in patients with AA. Ultrasound images of AA vary according to the stage of the disease and in comparison with AGA, SebD, and healthy individuals.
RESUMEN
Introduction: The skin is the typically and predominantly affected organ in patients after allogeneic hematopoietic stem cell transplantation (alloHSCT). The supportive therapy in patients after alloHSCT includes especially ultraviolet protection and the use of emollients. Aim: Due to the lack of studies regarding epidermal barrier function in patients with alloHSCT, our aims were to monitor dermatologically patients 1 year after the procedure with special emphasis on epidermal barrier function and to evaluate the properties of epidermal barrier function in patients with confirmed chronic GvHD (cGvHD). Material and methods: Our pilot study included 30 patients after alloHSCT and 20 healthy controls. In the group of patients after alloHSCT there were 10 individuals who were monitored dermatologically (including evaluation of skin, mucosae, nails and hair) within 1 year after the procedure (subgroup 1) and 20 patients with previously confirmed cGvHD (subgroup 2). We evaluated transepidermal water loss (TEWL), skin hydration and skin color. The clinical assessment and all noninvasive evaluations in patients included in subgroup 1 were performed before (at baseline) and 3, 6, 9 and 12 months after the procedure, while in subgroup 2 they were performed once. Results: In subgroup 1 we did not observe significant differences between baseline results and periods of assessments in TEWL values or corneometry, erythema and melanin measurements. In subgroup 2 the highest TEWL values and the lowest corneometry results were observed in patients with sclerodermoid chronic cutaneous GvHD in comparison to patients with lichenoid chronic cutaneous GvHD and patients with cGvHD but without skin lesions. TEWL values and melanin level were significantly higher in patients with cGvHD than in controls. Conclusions: Our pioneer observations proved the disturbed epidermal barrier function among patients after alloHSCT. Therefore it seems that proper skin care, including photoprotection, should be recognized as a crucial component in long-term management of these patients.
