RESUMO
Two years after its inception, Young Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (Y-GRAPPA) has established itself as a productive network for junior investigators and clinicians. The group's achievements in the last year include updating the educational GRAPPA slide library, the "Bring a Derm" campaign to expand the GRAPPA community to include more dermatologists, and the publication of multiple "Do Not Miss" newsletters covering the highlights on PsDs from the major international conferences (American Academy of Dermatology [AAD] Annual Meeting, European Alliance of Associations for Rheumatology [EULAR] Congress, European Academy of Dermatology and Venereology [EADV] Congress, and American College of Rheumatology [ACR] Convergence).
RESUMO
BACKGROUND: Epidemiological studies indicate that onychomycosis may affect up to 79% of psoriatic patients. Onychomycosis in psoriatic patients is more commonly caused by yeasts comparing with non-psoriatic. OBJECTIVES: Evaluate the prevalence of fungi in nail psoriasis. Evaluate the association between direct mycological examination (DME) and mycological culture, Nail Psoriasis Severity Index (NAPSI) and systemic treatment for psoriasis. METHODS: Of 133 nails from 20 patients with nail psoriasis were evaluated as follows: 9 patients were using topical treatment and 11 were on systemic treatment. The assessment of psoriasis severity using NAPSI was performed in all psoriatic nails. The presence of fungi was confirmed in DME and culture. RESULTS: DME showed the presence of fungal elements in 45 nails (33.83%) with a predominance of blastoconidia (95.5%) No septate hyphae were seen. Mycological culture was positive in 36 (27.06%) samples. Among them, Candida grew in 31 (86.1%): Candida parapsilosis in 15 (48.38%), Candida spp in 14 (45.16%). No growth of dermatophytes was observed. Patients with systemic treatment showed a higher frequency of positive test (DME and culture) for fungi when compared to topic treatment (p:.006). There was a positive correlation between NAPSI, mycological culture and systemic treatment (p:.0063); the risk was four times higher (OR:4.0). LIMITATION OF THE STUDY: Sample size. CONCLUSION: These results are consistent with some previous reports, Candida was the fungus with higher frequency on the psoriatic nails, however, the role of these fungi is controversial (contamination x colonisation x infection). The fact that the immunosuppressive treatment increases the chance of fungal infection leads us to a greater attention to this patient profile, to prevent the intensification of nail psoriasis (Köbner phenomenon).

PASE (Psoriatic Arthritis Screening and Evaluation) was developed in the English language to screen for inflammatory arthritis among patients with psoriasis. It is 15 item self administered questionnaire with a score from 15 to 75. A higher score indicates a greater risk for inflammatory joint disease. The purpose of this study was to translate, adapt and validate this questionnaire into Brazilian Portuguese (PASE-P). METHODS: 465 patients diagnosed with psoriasis (158 with psoriatic arthritis confirmed by a rheumatologist according to the CASPAR criteria and 307 without) were evaluated in dermatology clinics. We performed the analysis of semantic equivalence in eight steps. For psychometric equivalence, we evaluated the data quality, reliability, construct validity, well-known groups and discriminant characteristics of the items, as well as a ROC curve to determine optimal PASE-P cutoff points in case identification and their sensitivity / specificity. The final version presented excellent reproducibility (CCI = 0.97) and reliability (Cronbach's alpha> 0.9). A cut-off point of 25 distinguished between patients with and without psoriatic arthritis, with sensitivity of 69.5 and specificity of 86.8. PASE-P proved to be culturally valid and reliable to screen for psoriatic arthritis in Brazilian patients with psoriasis.

Granulomatous reactions to tattoo ink are most commonly associated with mercury sulfide, a component of red pigments. Treatment options show limited results. Allopurinol, an inhibitor of xanthine oxidase, has been reported as a successful alternative treatment to granulomatous disorders, such as sarcoidosis and granulomatous reactions to fillers and tattoos. We report a case of granulomatous reaction to red tattoo pigment treated with allopurinol for 6 months. Good clinical improvement could be noticed during this time. Two months after we stopped the treatment, the lesion recurred. Allopurinol emerges as an important drug for the management of granulomatous reactions caused by tattoo pigments. Based on the significant clinical improvement noticed during its use, we recommend new studies to elucidate all the potential benefits of the use of allopurinol for the treatment of granulomatous reactions to tattoo ink.

OBJECTIVE: To determine the prevalence of psoriatic arthritis (PsA) in a large cohort of Brazilian patients with psoriasis (PsO) being seen at dermatology centers. METHODS: A multicenter study was conducted in 4 university dermatology clinics. In each center, consecutive patients with confirmed diagnoses of PsO were evaluated by a rheumatologist. Individuals were classified as having PsA according to the ClASsification criteria for Psoriatic ARthritis (CASPAR). Laboratory tests and radiographs were performed, as needed, based on the clinical judgment of the rheumatologist. RESULTS: A total of 524 patients with PsO were evaluated. The mean age was 48.5 ± 14.5 years, 50% were women, and the mean PsO duration was 15.4 ± 11.7 years. A diagnosis of PsA was documented in 175 patients (33%), of whom 49% were newly identified by the rheumatologist. Most individuals with PsA (72%) had peripheral involvement, 11% had isolated axial involvement, and 17% had both peripheral and axial involvement. Dactylitis occurred in 20% and clinical enthesitis in 30% of the patients. Laboratory and/or radiograph tests were necessary for a definitive diagnosis of PsA in 42 of 175 individuals (24%). CONCLUSION: In our study, one-third of Brazilian patients with PsO, followed in dermatology settings, were diagnosed with PsA by a rheumatologist. Almost half of subjects with PsA had no previous diagnosis. A collaboration between dermatologists and rheumatologists is greatly needed to establish earlier PsA diagnoses and adequate multidisciplinary management.

Chemotherapy drugs can affect the skin and its appendages. Several clinical presentations can be observed, depending on the affected structure. The most common dermatological side effect is chromonychia. The main causative agents are: (1) cyclophosphamide, which can provoke a diffuse, black pigmentation, longitudinal striae and dark grey pigmentation located proximally on the nails; (2) doxorubicin, which promotes dark brown bands alternating with white striae and dark brown pigmentation in transverse bands, and (3) hydroxyurea, which produces a distal, diffuse, dark brown pigmentation. In the majority of cases, the effects are reversible after the suspension of the causative agent for a few months. We report a patient who developed chromonychia while undergoing treatment with cyclophosphamide, vincristine, doxorubicin, dexamethasone, methotrexate and cytarabine for acute lymphocytic leukemia.
RESUMO
Flagellate dermatitis shows very characteristic lesions: linear erythema or hyperpigmentation in various areas of the skin. It is a side effect of bleomycin, an immunosupressive drug used for several types of cancers. All physicians must be aware of this disease so they can make a rapid diagnosis and interrupt the causative agent. Our patient presented during chemotherapy for a Hodgkin's lymphoma pruritic, erythematous lesions on the lower limbs and the back diagnosed as flagellate dermatitis due to bleomycin.

IMPORTANCE: Golimumab is a human monoclonal antibody, used for rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. Adverse reactions are increasing with this class of medication (tumor necrosis factor α inhibitors). OBSERVATIONS: The authors present a case of a female patient who presented with psoriasis pustulosa after the use of golimumab for rheumatoid arthritis. CONCLUSIONS AND RELEVANCE: Paradoxically, in this case, golimumab, which is used for psoriasis, induced the pustular form of this disease. We are observing an increasing number of patients who develop collateral effects with tumor necrosis factor α inhibitors, and the understanding of the mechanism of action and how these adverse reactions occur may contribute to avoid these sometimes severe situations.
RESUMO
Lipoidoproteinose é uma genodermatose rara, caracterizada pelo envolvimento multissistêmico por depósito intracelular de material hialino amorfo. É causada por uma mutação no gene ECM1. Clinicamente, os pacientes podem apresentar rouquidão e espessamento cutâneo e mucoso. Uma grande variedade de anormalidades neurológicas pode estar presente quando o sistema nervoso central estiver envolvido.
