    Introduction: Acne occurring in adults over the age of 25 years is known as acne tarda or adult acne. Three types of adult acne are recognized: persistent, late-onset, and recurrent acne. Most studies do not compare the characteristics between the three vari-ants. In addition, little is known about adult acne in males. This study describes the epidemiological factors of adult acne and investigates certain triggering factors by sex and different types of adult acne. Methods: A multicenter, prospective, descriptive study was conducted. Patients with adult acne and an acne-free control group were compared regarding medical history, family history, smoking and drinking habits, and dietary factors. In addition, triggering and prognostic factors were investigated by sex and three different types of acne: persistent, late-onset, and recurrent acne. Results: The participants included 944 (88.56%) female and 122 (11.44%) male patients with adult acne, and 709 (73.85%) female and 251 (26.15%) male control patients. The consumption of crackers, chocolate, and pasta was significantly more common in the acne group than in the control group (p = 0.017, 0.002, and 0.040, respectively). Male patients with adult acne had a significantly longer disease duration than female patients with adult acne (p = 0.024). The most common type of acne was recurrent acne, followed by persistent and late-onset acne. Among patients with persistent acne, 14.5% had polycystic ovary syndrome (PCOS), whereas 12.2% of patients with recurrent acne and 11.1% of patients with late-onset acne had PCOS. Severe acne was more com-mon in the persistent acne type (28.13%). The cheek (59.90%) was the most common involvement area, and stress (55.23%) was the most common triggering factor regardless of sex. Conclusions: Although adult female and male patents with adult acne share similar triggering factors, the involvement areas can differ, which may indicate the additional hormonal etiology of female adult acne. Further epidemiological studies on adult acne in both sexes may illuminate the pathogenesis of the disease, thus making possible the development of new treatment strategies.

    Altunay, IK; Güngör, IE; Ozkur, E; Aydin, C; Manav, V; Ozden, HK; Ertekin, SS; Calikoglu, EE; Erdogan, HK; Taskin, B; Ficicioglu, S; Memet, B; Gürok, NG; Ermertcan, AT
    Background: Tattoos are very popular in today's world. Objectives: The aim of this study was to determine the demographics, the characteristics of tattoos, motivations for getting tattoos, tattooing practices and tattoo regret. Materials and Method: This multi-centre, cross-sectional study was conducted among. 302 patients attending to the dermatology outpatient clinics and having at least one tattoo. A questionnaire form including all needed data about patients, tattoo characteristics and possible reasons for obtaining tattoos was designed and applied to all participants. Results: Of 302 patients, 140 (46,4%) were females and 162 (53,6%) were men. The mean age was28,3 +/- 8,1 years (min-max, 16-62) for all study group, 53% of participants (n = 160) had at least one tattoo involving letters or number, 80 participants (26%) stated regret for at least one of their tattoos, and 34 of them (42,5%) had their unwanted tattoo removed or camouflaged with a new tattoo. The most common reason for regret was 'not liking the tattoo anymore'. The most common motivations for having tattoos were 'to feel independent', 'to feel better about himself/herself' and 'to look good'. Women had higher scores than men regarding tattoo motivations of 'to be an individual' and 'to have a beauty mark'. Conclusion: Given the rates, tattoo regret is a significant issue and as motivations differ between genders, age groups and other demographic characteristics; tattoos are not just an ink or drawing on the body, but a tool for individuals to express themselves and to construct self-identity. Tattoos have deep symbolic meanings for emotions, and they may be a clue for behavioural patterns of individuals.

    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-alpha 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.

    Background: The differentiation between the pemphigoid diseases is essential for treatment and prognosis. In Turkey, data on the incidence of these diseases are insufficient. Our aim in this study is to determine the incidence, demographics and clinical characteristics associated with diseases of the pemphigoid group. Methods: We prospectively analysed 295 patients with pemphigoid who visited dermatology clinics of tertiary referral hospitals in 12 different regions of Turkey within a year. The diagnosis was based on clinical, histopathological, direct immunofluorescence (DIF) and serological (multivariant enzymelinked immunosorbent assay [ELISA], indirect immunofluorescence and mosaic-based BIOCHIP) examinations. Clinical and demographic findings, aetiological factors and concomitant diseases observed in the patients were recorded. Results: A total of 295 (female/male ratio: 1.7/1) patients with pemphigoid were diagnosed in 1-year period. The overall incidence rate of pemphigoid diseases was found to be 3.55 cases per millionyears. The ratio of pemphigoid group diseases to pemphigus group diseases was 1.6. The most common pemphigoid type was bullous pemphigoid (BP, 93.2%). The others were epidermolysis bullosa acquisita (3.1%), pemphigoid gestationis (2.4%), linear IgA disease (1%) and mucous membrane pemphigoid (0.3%). The most common (26.8%) possible trigger of the bullous pemphigoid was gliptin derivative drugs. The most common concomitant diseases with pemphigoid were cardiovascular (27.8%) and neurological diseases (23.7%). Conclusions: This study showed that the increased frequency of bullous pemphigoid reversed the pemphigoid/pemphigus ratio in Turkey. Further studies are warranted regarding the reasons for this increase.
