Our results revealed that high number of patients with PV may present with active ENT lesions, furthermore patients with ear, nose and throat involvement may be asymptomatic and active lesions may be found in patients without any ENT symptoms. Therefore it should be considered that to understand the real extent of PV involvement, endoscopic ENT evaluation should be performed in patients with or without symptoms.

Background Generalized pustular psoriasis (GPP) is a rare and severe inflammatory disease characterized by widespread and superficial sterile pustules on an erythematous background. Objectives This multicentre study aimed to determine the clinical profile and course in a large cohort of patients with GPP. Methods One hundred and fifty‐six GPP patients (mean age, 44.2 ± 18.7 years) who met the diagnostic criteria of the European Consensus Report of GPP were included in the study. Sociodemographic characteristics, quality of life, triggering factors of the disease, clinical, laboratory, treatment and prognostic features were evaluated. Results 61.5% of the patients were female. The rate of working at or below the minimum wage (≤$332.5/month) was 44.9%. Drugs (36.5%) were the most common trigger. While hypocalcaemia (35.7%) was the most important cause of GPP during pregnancy, systemic steroid withdrawal (20%) was the most frequently reported trigger for infantile/juvenile and mixed‐type GPP (15%) (P < 0.05). Acute GPP (53.8%) was the most common clinic. Nails were affected in 43.6% of patients, and subungual yellow spots (28.2%) were the most common change. In annular GPP, fever (P < 0.001) and relapse frequency (P = 0.006) were lower than other subtypes, and the number of hospitalizations (P = 0.002) was lower than acute GPP. GPP appeared at a later age in those with a history of psoriasis (P = 0.045). DLQI score (P = 0.049) and joint involvement (P = 0.016) were also higher in this group. Infantile/juvenile GPP was observed in 16.02% of all patients, and arthritis was lower in this group (24.4 vs. 16%). GPP of pregnancy had the worst prognosis due to abortion observed in three patients. Conclusions Recent advances in treatment have improved mortality associated with GPP, but abortion remains a significant complication. Although TNF‐α inhibitors have proven efficacy in GPP, they can also trigger the disease. Mixed‐type GPP is more similar to acute GPP than annular GPP with systemic manifestations and course.

Psychosocial effect of pediatric psoriasis was shown to extend beyond the individual, highlighting the importance of addressing patient and caregiver quality of life concerns in an integrated approach.

Even though we could not show a better efficacy than placebo, autohemotherapy resulted in a marked decrease in disease activity and improvement in quality of life scores in CU patients.

Background. Thyroid disorders may affect all of the organ systems of the body and they are also highly associated with a wide variety of skin disorders. The aim of this study was to investigate the prevalence of thyroid function abnormalities and thyroid autoimmunity in patients with pemphigus vulgaris (PV) and to determine the association between thyroid disorders and clinical involvement and systemic corticosteroid treatment in patients with PV. Methods. The study consisted of eighty patients with PV and eighty healthy individuals. Thyroid functions (fT3, fT4, and TSH) and thyroid autoimmunity (anti-thyroid peroxidase (anti-TPO), and anti-thyroglobulin (anti-Tg) antibodies) were investigated in both groups. Primary thyroid disease (PTD) was diagnosed with one or more of the following diagnostic criteria: (i) positive antithyroid antibodies, (ii) primary thyroid function abnormalities. Results. Significant changes in the serum thyroid profile were found in 16% (13/80) of the PV group and 5% (4/80) of the control group. Positive titers of antithyroid antibodies (anti-TPO and anti-Tg) were observed in 7 patients (9%) with PV and one in the control group (1,2%). Hashimoto thyroiditis was diagnosed in 9% of PV patients and it was found to be more prevalent in the mucosal form of PV. PTD was found in 13 of (%16) PV patients which was significantly high compared to controls. PTD was not found to be associated with systemic corticosteroid use. Free T3 levels were significantly lower in PV group compared to the control group and free T4 levels were significantly higher in PV group compared to the controls. Conclusions. PV may exist together with autoimmune thyroid diseases especially Hashimoto thyroiditis and primer thyroid diseases. Laboratory work-up for thyroid function tests and thyroid autoantibodies should be performed to determine underlying thyroid diseases in patients with PV.

Compared to control subjects, patients had higher proportions in populations with alopecia (P < 0.001), nail thinning (P = 0.02), brittle nails (P = 0.001), pruritus (P < 0.001), diffuse hyperhidrosis (P = 0.01), flushing (P = 0.001), and xerosis (P < 0.001). Onycholysis (P = 0.02), yellow skin (P = 0.04), periorbital edema (P = 0.03), psoriasis (P = 0.001), and palmoplantar hyperkeratosis (P = 0.007) were significantly more common in patients with autoimmune than nonautoimmune thyroid disease. A significantly higher percentage of patients with autoimmune rather than nonautoimmune thyroid disease had overall skin findings (P = 0.03) among the hyperthyroid patients.Conclusions: Our findings indicate that the presence of skin findings in a majority of thyroid patients significantly differs for certain cutaneous manifestations with respect to controls, autoimmune etiology, and thyroid functional status.

Livedoid vasculopathy is characterized by painful purpuric lesions on the extremities which frequently ulcerate and heal with atrophic scarring. It has been considered to be a vasculitic process but now there has been increasing evidence that abnormal coagulation plays a major role in the pathogenesis of this rare disorder. We report the case of a 19-year-old male who had been suffering from recurrent painful ulcerations on both lower legs with atrophic scars for 4 years. A biopsy specimen revealed vasculopathy, and laboratory studies showed resistance to activated protein C with factor V Leiden mutation. Treatment with oral warfarin led to rapid improvement of the lesions.

SummaryBackground and Design: Pediatric dermatology is a new topic in our country, and epidemiologic data is limited in this area.
