Psoriasis is a common chronic inflammatory skin disease with a significant socio-economic impact that can greatly affect the patients' quality of life. The prevailing dogma in the aetiology and pathophysiology of this complex disease is that skin cells, immune cells as wells as environmental factors contribute to psoriatic skin inflammation. For a better understanding of the disease pathogenesis, models are required that mimic the disease and which can be used to develop therapeutics. Over the last decades, in vitro human reconstructed skin models have been widely used in dermatological research and have also been developed to mimic psoriatic skin...

Intravenous immunoglobulin (IVIG) replacement therapy has been used in immune deficiency diseases for more than 50 years. The indications for this treatment have evolved, however, and IVIG therapy is now used in various diseases in which the immune system plays a prominent role. IVIG therapy has carved out a niche in dermatology for the treatment of such conditions as dermatomyositis, autoimmune bullous diseases, and toxic epidermal necrolysis. Special attention has been paid to this therapy in recent years...

Individuals with cutaneous diseases of the external genitalia often initially present to their primary care provider. When present, these conditions may be associated with considerable physical symptoms and psychological distress. Dermatoses affecting the genitals may be of infectious, inflammatory, or neoplastic cause, and can be processes confined to the genitalia or a manifestation of a more widespread dermatologic condition. This article provides a guide to recognizing and managing common genital dermatoses and when to refer for specialist opinion...

BACKGROUND: Melanoma surveillance serves to identify new primary melanomas and curable locoregional or early distant recurrences. Although an optimal melanoma surveillance strategy has not been determined, several clinical guidelines exist. OBJECTIVE: The aim of this study was to identify demographic and clinico-pathologic variables associated with poor adherence to National Comprehensive Cancer Network (NCCN) melanoma surveillance guidelines. DESIGN: We retrospectively reviewed the initial five-year dermatology follow-up visit frequencies of melanoma patients and extracted basic demographic and clinical data from their medical records...

Clinical trials have several important limitations for evaluating the safety of new medications, leading to many adverse events not being identified until the postmarketing period. Descriptive studies, including case reports, case series, cross-sectional, and ecologic studies, help identify potential safety signals and generate hypotheses. Further research using analytic study methods, including case-control studies and cohort studies, are necessary to determine if an association truly exists and to better understand the potential for causation...

Dermatophytes are associated with superficial infections in humans worldwide. The aim of the present study was to determine the species distribution and susceptibility patterns of clinical dermatophytes. Samples received for routine mycological processing from 124 suspected cases attending a dermatologic clinic in a tertiary care hospital were included in the study. On direct microscopy, 74.1% (92/124) were positive and 53.2% (66/124) grew on culture. The isolates were comprised of Trichophytoninterdigitale (56%) followed by Trichophytontonsurans (25...

BACKGROUND: Malignant melanoma is a disease which has a cutaneous origin in 90% of the patients, but in rare cases, it could be discovered as secondary deposits with unknown primary site. Metastatic Malignant Melanoma occurs without a primary site in about 3% of all melanoma patients, and it could be divided into two main groups: metastatic lymph nodes' involvement or non-lymph nodes disease. The lack of unified classification and staging system, provided by AJCC (2009), as well as the lack for curtain diagnostic and therapeutic protocol, prompt us to raise the question what is the right way to precede in cases of metastasis of the lymph nodes, without evidence of a primary tumour? CASE REPORT: We report a case of 67-years- old woman who presented in the dermatology clinic after a surgical removal of an enlarged lymph node in her left femoral area, verified histologically as a metastasis of melanoma...

Although thiopurine S-methyltransferase (TPMT) genotyping to guide thiopurine dosing is common in the pediatric cancer population, limited data exist on TPMT testing implementation in diverse, multidisciplinary settings. We established TPMT testing (genotype and enzyme) with clinical decision support, provider/patient education, and pharmacist consultations in a tertiary medical center and collected data over 3 years. During this time, 834 patients underwent 873 TPMT tests (147 (17%) genotype, 726 (83%) enzyme)...

Toxic epidermal necrolysis spectrum (TENS) is a rare yet severe adverse drug reaction associated with a high mortality rate. Beyond supportive care, there is still no established therapy for TENS, although recent meta-analyses and UK guideline recommendations have attempted to offer a review of relevant literature on this difficult topic. As most directed treatments lack clear consensual evidence, care centres often resort to establishing their own strategies. As Canada's largest adult burn centre and the provincial reference centre for most burn patients in Ontario, our team at the Ross Tilley Burn Centre, in collaboration with the Department of Dermatology at Sunnybrook Health Sciences Centre, Toronto, Canada, has managed over 60 confirmed cases of TENS over the past 2 decades...

INTRODUCTION: Tattooing has become a popular practice in western countries, particularly among younger populations. Tattoos, however, can cause complications, such as infections, allergic or foreign-body reactions, and even systemic inflammatory responses. PATIENTS AND METHODS: We conducted a retrospective study of all patients seen for tattoo-related complications at our skin allergy unit between January 2002 and December 2016. RESULTS: We studied 23 patients...

Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a significant increase in the incidence of sexually transmitted diseases, leprosy, melasma, pruritus and hidradenitis suppurativa. However, a prominent reduction in scheduling of appointments for surgeries of benign lesions, drug reactions, urticaria and superficial mycoses was detected...

Kaposi 's sarcoma (KS) is a rare multifocal angioproliferative disease associated with human herpes virus 8 (HHV-8) infection, characterized by cutaneous nodules or plaques especially on the lower limbs. Some skin modifications, such as chronic lymphedema, plantar hyperkeratosis and interdigital desquamation, may be associated with consequent impairment of the local immunosurveillance and increased risk of some bacterial or mycotic infections. With the objective of evaluating if bacterial or mycotic infections in KS patients are supported by different microorganisms compared to control patients, we performed an observational retrospective study, comparing positive cultural swabs of interdigital intertrigo of KS patients with positive cultural swabs of interdigital intertrigo of patients admitted to our dermatologic unit during the last 10 years...

BACKGROUND/OBJECTIVES: There remains a lack of investigation into which factors patients and families value the most in their experience at pediatric dermatology clinics. Most of the current literature on quality improvement in dermatology does not encompass the pediatric population. To determine the drivers that are most predictive of a positive patient experience, we observed the indirect relationship between several factors of the patient experience and their role in patient satisfaction...

BACKGROUND: Clinical practice frequently involves the practitioner touching patients' bodies in areas that are highly personal. If inappropriately performed, such intimate touch may result in much anxiety, confusion and misinterpretation. Examination of evidence is necessary to guide practice in this area to mitigate risks and foster optimal clinician-patient relations and care. OBJECTIVES: The objective of this qualitative systematic review was to identify and synthesize findings on the perceptions, experiences and preferences of patients receiving a clinician's touch during intimate care and procedures INCLUSION CRITERIA TYPES OF PARTICIPANTS: The current review considered studies that included patients who had received a clinician's touch during intimate care and procedures...

PURPOSE: Many childhood diseases often present with skin abnormalities with which radiologists are largely unfamiliar. Knowledge of associated dermatologic manifestations may aid the radiologist in confirming the diagnosis and recommending targeted imaging of affected organs. METHODS: We review the imaging findings in childhood diseases associated with dermatologic manifestations. FINDINGS: Diseases include dermatologic findings which herald underlying malignancy (Neuroblastoma, leukemia/lymphoma, Langerhans cell histiocytosis),are associated with risk of malignancy (Epidermolysis Bullosa, basal cell nevus syndrome, Cowden's syndrome, Tuberous Sclerosis),or indicate a systemic inflammatory/immune disorder (Kawasaki's disease, Henoch Schonlein Purpura, systemic lupus erythematosus, scleroderma, sarcoidosis, dermatomyositis and immune thrombocytopenic purpura)...

All melanoma suspected patients must be confirmed histologically and resected. Sentinel node biopsy must be done when tumor is over 1 mm or if less with high-risk factors. Adjuvant therapy with interferon could be offered for patients with high-risk melanoma and in selected cases radiotherapy can be added. Metastatic melanoma treatment is guided by mutational BRAF status. BRAF wild type patients must receive anti-PD1 containing therapy and BRAF mutated patients BRAF/MEK inhibitors or anti-PD1 containing therapy...
