RESUMO
BACKGROUND: Hidradenitis suppurativa (HS) causes significant physical, social, and psychological burdens. Internalized stigma, acceptance of negative attitudes and stereotypes of society regarding a person's illness, has not been studied previously in HS. OBJECTIVES: The objective of this study was to investigate the internalized stigma state of HS patients and identify the factors affecting it. METHODS: This multicenter, prospective, cross-sectional study included 731 patients. Internalized Stigma Scale (ISS), Hurley staging, Physician Global Assessment, Dermatology Life Quality Index (DLQI), Skindex-16, Beck Depression Inventory-II (BDI-II), and Visual Analog Scale (VAS)-pain score were used in the study. RESULTS: The mean ISS value (57.50 ± 16.90) was comparable to the mean ISS values of studies in visible dermatological and various psychiatric diseases. A significant correlation was found between the mean values of ISS and all disease activity scores, quality of life measures, BDI-II, and VAS-pain scores. Obesity, family history, low education and income level, vulva/scrotum involvement and being actively treated are significant and independent predictive factors for high internalized stigma in multivariate analysis. CONCLUSIONS: HS patients internalize society's negative judgements, which may create a profound negative effect on access to health care. Therefore, in addition to suppressing disease activity, addressing internalized stigma is fundamental for improving health care quality.

BACKGROUND: Hidradenitis suppurativa (HS) is an independent risk factor for the development of subclinical atherosclerosis. Tumour necrosis factor (TNF) inhibitors are effective for the treatment of recalcitrant moderate-to-severe HS. However, the effect of treatment with TNF inhibitors on subclinical atherosclerosis in HS patients has not been previously investigated. OBJECTIVES: In this study, we aimed to assess changes in biochemical parameters (fasting blood glucose and lipid levels) and carotid intima-media thickness (CIMT) values in Hurley stage II and III HS patients undergoing treatment with TNF inhibitors. METHODS: This was a single center prospective study including 30 patients with Hurley stage II and III HS and 30 healthy controls (HCs). Baseline values of biochemical parameters and CIMT were compared to the values recorded after at least 6 months of TNF inhibitor therapy. RESULTS: CIMT values of the HS patients significantly exceeded those of HCs (for right p = 0.011 and for left p = 0.017). After at least 6 months of TNF inhibitor therapy, there was a statistically significant decrease in fasting blood glucose (p = 0.001), whereas total cholesterol levels significantly increased (p = 0.001). CIMT values also significantly increased (for right p = 0.02 and for left p = 0.01). STUDY LIMITATIONS AND CONCLUSIONS: Small sample size is limitation of the current study. Our study shows that patients with Hurley stage II and III HS undergoing TNF inhibitor therapy are under risk for progression of subclinical atherosclerosis.

BACKGROUND: In this study, we aimed to investigate different types of celiac antibodies in psoriasis patients and to see if the presenceof the antibodies was associated with other variables. METHODS: We included patients with plaque psoriasis who were followed up in our dermatology clinic between February 2019 and February 2021 and added a healthy control group for comparison. The antibodies studied were serum antitissue transglutaminase (tTG)-IgA, tTG-IgG, antigliadin antibody (AGA)-IgA, and AGA-IgG. The patients' records were used to note age, sex, the pattern of psoriasis involvement, psoriasis area and severity index (PASI), presence of hypertension, presence of type 2 diabetes mellitus, use of methotrexate, and use of biologic agents. RESULTS: Sixty-five psoriasis patients (31 F, 34 M, mean age: 38.9 ± 15.2) and 65 controls (42 F, 23 M, mean age: 40.7 ± 13.2) wereincluded in the study. There was no significant difference in antibody levels between the groups: tTG-IgA (2.4 U/mL vs 3.2 U/mL, p = 0.11), tTG-IgG (2.2 U/mL vs 3.2 U/mL, p = 0.74), AGA-IgA (2.4 U/mL vs 3.5 U/mL, p = 0.068), and AGA-IgG (3.2 U/mL vs 4.2 U/mL, p = 0.15). One patient from the psoriasis group only had borderline positive antibody levels whereas the rest of the psoriasis and control group had negative levels. Hypertensive psoriasis patients had significantly higher AGA-IgA titers compared to normotensive psoriasis patients (4.2 U/mL vs 2.3 U/mL, p = 0.005). DISCUSSION: There was no increase in the AGA-IgA/IgG and tTG-IgA/IgG levels in psoriasis patients compared to the healthy population. However, hypertensive psoriasis patients had higher AGA-IgA levels compared to normotensive ones.

BACKGROUND: Previous literature regarding the frequencies of each subtype of female pattern hair loss is contradictory and the subtypes have not been compared to each other in terms of their epidemiologic characteristics and relationships with comorbid diseases. OBJECTIVES: The aims of this study are to determine the frequency and the relationship with comorbidities for each subtype, and to determine the relationship of clinical stage with age and comorbid diseases. METHODS: This is a prospective cross-sectional study involving patients with a definitive diagnosis of female pattern hair loss. The age, age at the time of diagnosis, family history for androgenetic alopecia, clinical subtype, clinical stage, and comorbid conditions were noted for each patient. SPSS version 21 (IBM SPSS) was used for statistical analysis. RESULTS: Advanced stages of female pattern hair loss are related to increased age, menopausal state, and hypertension. Acne vulgaris is more prevalent in earlier stages. Hirsutism and acne vulgaris are more commonly encountered in the Ludwig and Hamilton subtypes. Hypertension is more frequent in Ludwig subtype. LIMITATIONS: The confounding effect of age on the relationship between clinical subtype and comorbid diseases. CONCLUSION: The relationship between comorbid diseases and stage in specific subtypes can guide us to the diagnosis of undiagnosed comorbid diseases.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is an uncommon systemic adverse drug reaction. Furthermore, it is a unique syndrome encompassing various manifestations of fever, facial edema, eosinophilia, atypical lymphocytosis, and organ dysfunction. Since there are no large prospective studies concerning DRESS syndrome, current treatment modalities for DRESS have been mainly determined based on various case reports and expert opinions. Corticosteroids are the mainstay of therapy after the cessation of the culprit drug. Although most cases recover within a couple of months, some may persist and even progress despite 1 mg/kg/day of prednisolone or its equivalent. We herein present two cases of severe DRESS syndrome. Both cases presented with organ dysfunction and remained unresponsive to initial treatment with 1 mg/kg/day of intravenous methylprednisolone. Therefore, plasmapheresis or pulse steroid therapy (250 mg/day methylprednisolone for 3 days) was used. In the follow-up period, the patients' clinical conditions improved dramatically without recurrence. We aimed to share our experience in recognizing and managing severe DRESS cases in this manuscript. Furthermore, we reviewed the literature in comparison with the present cases. In conclusion, plasmapheresis or pulse steroid therapy (250 mg/day of methylprednisolone for 3 days) can be used to treat difficult DRESS cases where organ failure is about to happen.

There is widespread concern about treatment of psoriasis in COVID-19 pandemic. We aimed to evaluate the epidemiological data, clinical characteristics, treatment features of the psoriasis patients during the pandemic period. We conducted a study in dermatology clinics of seven different tertiary centers. All adult psoriasis patients who were followed up between 11 March 2020 and 28 June 2020, were phone called or questioned in their visit to their follow-up clinics. A semistructured questionnaire was applied and patients' demographics and disease characteristics were recorded. Of 1322 patients, 52.4% were male, and 47.6% were female. According to the questionnaire responses, 964 (72.9%) of these patients could not communicate with their physician during this period, remained 358 (27.1%) patients contacted the physician by phone, email, or hospital visit. From the patients diagnosed as probable/confirmed COVID-19, 14 were female, and 9 were male. Nine of 23 (39.1%) patients were using biologic treatment. There was no statistically significant difference in terms of hospitalization from COVID-19 between the patients using biologics (n = 9) and those who did not (n = 14) (P = 1.00). No mortality was observed among them. Obesity, smoking, age, and accompanying psoriatic arthritis were not among the risk factors affecting the frequency of COVID-19. We only encountered an increased risk in diabetic patients. Also, an exacerbation of psoriasis was observed with the infection. No difference was found in patients with psoriasis in terms of COVID-19 infection in patients who use biologics and those who don't.

INTRODUCTION: Novel anti-cancer drugs such as targeted cancer therapies and immune check-point inhibitors (ICIs) have adverse events, especially concerning the skin. The aim of this study is to report an overview of the commonly consulted dermatological side effects of ICIs and targeted cancer therapies in clinical practice, along with their management. METHODS: In this single-center study, we evaluated consecutive oncological patients who were referred from the oncology outpatient clinic to the dermatology outpatient clinic due to skin side effects of ICIs and targeted therapies. All patients were examined and treated at the same day of referral by experienced dermatologists. Patient characteristics, clinical findings, diagnostic workups and treatments were retrieved from outpatient records. RESULTS: Sixty three patients were enrolled. Most common diagnoses were lung carcinoma, melanoma and colon carcinoma. Fifty patients (79%) were using targeted therapies while 13 (21%) were using ICIs. Xerosis was the most common side effect (44%), followed by acneiform rash, paronychia, eczema and pruritus. Majority of the side effects were grade 2 and 3. Psoriasis was a common side effect of ICIs. One patient had a newly developed dysplastic nevus on vemurafenib treatment. Oncological treatment was not withheld in any of the patients. CONCLUSIONS: This study revealed the most commonly consulted skin side effects of novel anti-cancer drugs and their management in daily practice. We underlie the importance of collaborative work of oncology and dermatology professionals as early management of cutaneous side effects of targeted therapies and ICIs improves patient outcomes.

Mycosis fungoides (MF) is a chronic disease, causing serious morbidities and mortality. This study was designed to measure depression and anxiety levels in MF patients, and quality of life (QoL) assessments and to compare the results with controls. Fifty-two patients with a diagnosis of MF and 52 age and sex matching healthy controls were enrolled in this study. Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and the 36-Item Short Form Health Survey (SF-36) were administered to all patients and controls. Mean BAI and BDI scores of the patients with MF were significantly higher than controls. In case of the SF-36, general health perception, emotional, and social functioning scores were significantly lower in MF patients. Depression scores of the patients' were positively correlated with the age of disease onset and negatively correlated with physical functioning scores. Significant negative correlation was detected between eight subscales of the SF-36 and BDI and BAI scores. This study has demonstrated that there is significant impairment of QoL in MF patients MF, with higher anxiety and depression levels, when compared to control group. As the disease progresses, level of depression increases and patients' general health perception deteriorates.

Since the COVID-19 infection first appeared in December 2019, patient profile of outpatient and inpatient clinics has changed. Various cutaneous findings associated with COVID-19 have been reported in the literature. The main objective of this study was to describe and analyze the profile of the consultations requested from dermatology department during the COVID pandemic. Retrospective, cohort study. In this study, we observed the dermatology consultations of the hospitalized patients over a period of 2 months, corresponding to the peak of COVID outbreak in a tertiary care hospital in Turkey. We reviewed the inpatient dermatology consult database retrospectively. Both pediatric and adult dermatology inpatient consultations were evaluated. A total of 166 inpatient dermatology consultations were requested from dermatology department during March-May, 2020. The mean age of the patients was 53.12 (1-89) years. Almost 32.5% (n = 54) of dermatology consultations were requested from the COVID wards and the COVID intensive care unit. The second most common consultations were requested from internal medicine departments (n = 46, 27.7%). The most common indications for the consultations were cutaneous infections (36%), followed by inflammatory disorders (32%), and urticaria (11%). Dermatology consultations have an essential role on the management of hospitalized patients, especially at that pandemic time. Careful dermatological examination improves diagnostic accuracy in skin disorders and skin manifestations of COVID-19 infection that provides an early diagnosis and treatment, helps to improve the quality of the patient care and management.

The subacute cutaneous lupus erythematosus (SCLE) is a distinct subtype of lupus erythematosus (LE) representing specific clinical and serological features. Almost 20%-30% of the cases with SCLE are predicted to associated with medications. Thiazide diuretics, terbinafine, antiepileptic, and proton pump inhibitors are the best-known drugs to induce drug-related SCLE. Herein we want to present a 65-year-old female with alendronate induced SCLE, resistant to classical therapies, and respond well to intravenous immunoglobulin (IVIG), suggesting that IVIG could be an alternative treatment in patients resistant to classical treatment protocols.

Erythroderma, or exfoliative dermatitis, is an inflammatory disorder characterized by erythema and scaling, affecting most of the skin surface. It may be a result of many different causes such as previous dermatoses (psoriasis, eczema, atopic dermatitis [AD], pityriasis rubra pilaris, and pemphigus foliaceous), drug reactions, malignancies (mycosis fungoides [MF], Sézary syndrome, adult T cell leukemia/lymphoma), infections, and idiopathic disorders. Regardless of the etiology, the clinical appearance of erythroderma is similar in all patients. The most prominent physical examination findings in almost all patients are diffuse erythema and scaling. In a 2-year period, 47 patients who were hospitalized and treated in our department were included in the study. We classified patients into seven subgroups: psoriasis, AD, drug-induced erythroderma, MF, pityriasis rubra pilaris, bullous pemphigoid, and polymorphous light eruption. All patients had a biopsy during the acute stage and diagnoses were histopathologically confirmed. Some patients had multiple biopsies for histopathological confirmation. In our study, the majority of the patients were men over the age of 54. The most common etiological cause of erythroderma is psoriasis. We aim to analyze clinical, laboratory, and histopathological findings of erythrodermic inpatients prospectively in Istanbul University-Cerrahpasa Cerrahpasa Medical Faculty between January 2018 and 2020.

BACKGROUND: Hidradenitis suppurativa is a chronic, inflammatory, recurrent disease with recurrent abscesses, and sinus tract formation leading to scarring. Calprotectin has immunomodulatory, antimicrobial, and antiproliferative properties and is a calcium-binding protein primarily found in the neutrophil cytoplasm. In recent years, a significant relationship between the activity of various diseases and the level of calprotectin has led to the conclusion that there may be a similar relationship in hidradenitis suppurativa. OBJECTIVE: To determine the relationship between disease activity and fecal calprotectin levels in patients with hidradenitis suppurativa. METHODS: Fifty patients with hidradenitis suppurativa (case group) who present to the Dermatology and Venerology Department between December 6, 2017, and April 6, 2018, and 36 healthy volunteers (control group) were enrolled in our study. Fecal calprotectin levels we requantitatively calculated using enzyme-linked immunosorbent assay. RESULTS: In patients with active hidradenitis suppurativa, the level of stool calprotectin was higher than that of patientsin remission, and this difference was statistically significant (p < .001). There was no statistically significant correlation between disease stage and fecal calprotectin levels in patients with hidradenitis suppurativa (p = .14). Age, sex, smoking and alcohol use, anti-TNF-α treatment, and fecal calprotectin levels were not significantly correlated. In our study, fecal calprotectin levels in patients with active hidradenitis suppurativa were higher than inpatients in remission (p < .001). CONCLUSION: Fecal calprotectin can beused as a marker of disease activity in hidradenitis suppurativa.

Skin problems following rhinoplasty may cause dissatisfaction concerning the esthetic expectations of the patients. This study was conducted to determine whether nasal skin type has an effect on skin problems after rhinoplasty. Thirty-five patients undergoing rhinoplasty in our tertiary referral center between May 2018 and August 2019 were included in the study. The nasal skin sebum level was measured with Sebumeter preoperatively and patients were divided into two groups according to the median sebum level. Among the 35 patients, half of them with higher nasal skin sebum were categorized as oily skin group (n = 17; 14 males, 3 females; mean sebum level: 200.3 ± 26.9), and the other half were categorized as dry skin group (n = 18; 10 males, 8 females; mean sebum level: 101.9 ± 38). Periorbital edema and ecchymosis were assessed at postoperative days 1, 3, and 7. Acne and seborrhea severity determined with Global Acne Grading System and Seborrheic Dermatitis Area Severity Index the day before operation and postoperative days 7 and 14 and months 1, 3, and 10. Compared with dry skin group, upper eyelid ecchymosis score at postoperative day 7 was statistically higher in oily skin group (p = 0.044). There was no significant difference in upper eyelid edema scores between postoperative days 1 and 3 for oily skin group (p = 0.020). No statistically significant differences were found for acne and seborrhea severity. Nasal skin sebum levels may affect periorbital edema and ecchymosis after the procedure but no significant effect has been observed for acne and seborrhea. Predicting the effect of nasal skin types on these problems may help the surgeon to inform patients more correctly.

Metabolic syndrome, a commonly observed pathology and a global health issue, is closely related to the skin and thus dermatologists. The skin contributes to the development of metabolic syndrome and it is an end organ for it. Metabolic dysfunction is related to many skin disorders, some of which with high association and some of which with lower association. The diseases of highest association will be discussed in this article. These diseases are acne vulgaris, acanthosis nigricans, hidradenitis suppurativa, and psoriasis vulgaris.

Lipid mediators play a main role in the complex course of cutaneous inflammatory reactions. They regulate a wide spectrum of cellular processes such as cell proliferation and apoptosis. In the early phase of inflammation, excessive amounts of lipid mediators are released and play a major role in the pathogenesis of skin diseases. Recent data suggest that lipid mediators are able to interfere with the pathogenesis of certain dermatologic diseases, seriously affecting patient quality of life. Acne, psoriasis, and atopic dermatitis are specific examples of skin diseases that may respond to treatment with medication affecting these metabolic pathways. The authors briefly present the current knowledge about the role of lipid mediators in common skin pathologies.

Cyclosporine, a member of the calcineurin inhibitor family, has immunomodulatory effects on T cells. It blocks the earliest stages of the immune response by binding to cyclophilin, thus inhibiting calcineurin. It was initially used for transplant patients to prevent transplant rejections. The main indication for cyclosporine in dermatology is severe psoriasis. Other dermatologic indications for the use of cyclosporine include atopic dermatitis, chronic idiopathic urticaria, pyoderma gangrenosum, and Behçet's disease.

OBJECTIVES: Behçet's disease (BD) is a chronic inflammatory disorder characterised by aphthous stomatitis, genital ulcerations, erythema nodosum-like manifestations and papulopustular lesions. While a neutrophilic vasculitis accompanies most skin lesions it is usually regarded that the papulopustular lesions in BD are similar to acne vulgaris (AV). The aim of our current study was to further assess the clinical and histopathological features of papulopustular lesions in BD and how these features compared to those of AV. METHODS: To analyse the histopathological features of BD and AV, 89 punch biopsies were taken from 58 BD (52 male, 6 female) and 31 AV patients (26 male, 5 female). Sections were evaluated in a blind manner by two different pathologists. A dermatologist who was blind to the patients' diagnosis counted the number of papules, pustules, comedones, folliculitis, cysts and nodules on the face, chest, back, upper and lower extremities. RESULTS: The number of papules, pustules and comedones was higher on the face in the AV group, whereas in the BD group, both number of papules and folliculitis on the back and that of folliculitis were higher on the lower extremities in the AV group. With the exception of comedone formation, which was more frequent among the AV patients [20/31 (64.5%) vs. 23/58 (39.6%), p=0.025] the presence of suppurative folliculitis/perifolliculitis, intrafollicular abscess formation, leukocytoclastic vasculitis or microorganisms were not useful in differentiating BD from AV. However, the interobserver agreement for histologic assessment was low. Kappa was 0.17 for suppurative foliculitis/perifol¬liculitis; 0.39 for intrafollicular abscess formation; 0.51 for leukocytoclastic vasculitis. CONCLUSIONS: In the BD group, although the inflammatory lesions located on the face were less than those in the AV group inflammatory lesions such as folliculitis on the legs were only seen, again in the BD group. The papulopustular lesions of BD could not be distinguished from AV by histology. Some of this might be due to high interobsever variation in interpretation. Acne is an inherent manifestation of BD.

BACKGROUND: The recognition of folliculotropic mycosis fungoides (FMF) may pose diagnostic challenges, owing to the variety of histopathological findings. OBJECTIVE: In this study, our aim is to describe the broad spectrum of the histopathological patterns in a total of 86 biopsies from 38 patients with FMF, together with the clinical features. RESULTS: The most frequent histopathologic pattern was the folliculocentric/folliculotropic pattern, with or without follicular mucinosis. Keratin-filled cysts and comedones were the second most common pattern in the biopsies. Other less common findings included widening of the hair follicle orifis with keratotic plugging, reminiscent of keratosis pilaris, granuloma formation, eosinophilic or suppurative folliculitis and basaloid folliculolymphoid hyperplasia. Coexisting syringotropism was present in some biopsies. The CD4 : CD8 ratio was at least 4 : 1 or more in most biopsies. Grouped follicular papules and patch/plaque lesions with follicular prominence were the most frequent clinical findings. Folliculocentric lesions such as milia, cysts and acneiform lesions, alopecia, loss of hair or eyebrows were also seen. In 6 out of 38 (15.8%) patients, transformation to large-cell lymphoma was observed during the follow-up. CONCLUSION: The awareness and the identification of the various histopathological presentations of FMF by pathologists, as well as by clinicians, are imperative to prevent diagnostic errors.
