Evaluation of cardiovascular risk in patients with psoriatic disease in a multiracial population: a cross-sectional study.

BACKGROUND: Psoriatic disease (PD) is a chronic inflammatory disorder often associated with cardiovascular risk (CVR) factors such as obesity, hypertension, diabetes, dyslipidaemia and smoking. It is estimated that 2%-4% of the population worldwide has PD. Cutaneous lesions of psoriasis (PsO) may be associated with psoriatic arthritis (PsA) in up to 40% of patients. Studies have been carried out around the world with the aim of evaluating CVR in such patients. AIM: To determine CVR in a multiracial population with PsA or PsO from southeastern Brazil, which has a predominantly tropical climate, compared with controls. METHODS: A cross-sectional study was carried out in outpatients with PsO or PsA followed up at a quaternary referral hospital in Rio de Janeiro. The Framingham Risk Score (FRS) was used to predict cardiovascular events (CVEs) over 10 years in patients with PsO and PsA compared with controls. RESULTS: FRS was significantly higher at 10 years in patients with PsO (mean ± SD 16.3 ± 14) and PsA (18.0 ± 15) compared with controls (10.6 ± 9.5) (P = 0.01) and also increased with age. The chance of having a high FRS in the PsO and PsA groups increased by 0.30 and 0.23 times per year, respectively, compared with controls (PsO vs. controls 95% CI 0.090-1.00; PsA vs. controls 95% CI 0.08-0.75). CONCLUSION: In this multiethnic Brazilian population, both PsO and PsA were associated with higher CVR compared with controls. The frequency of high FRS was highest in the sixth decade of life for all three groups of participants. Annual assessment of patients with PD is necessary in order to prevent CVEs.

What to expect when AGEP is induced by terbinafine? Case report and critical review of the literature.

BACKGROUND: Acute Generalised Exanthematous Pustulosis (AGEP) is a rash with multiple sterile intraepidermal or subcorneal non-follicular pustules on edematous papules, with a sudden development and rapid evolution, triggered by drugs, vaccination, insect bites, exposure to mercury, and allergens. OBJECTIVES AND METHODS: We describe a female patient who developed extensive and abnormally prolonged AGEP following exposure to terbinafine and SARS-CoV vaccine. A detailed review of terbinafine-induced-AGEP cases was performed, with the aim of evaluating if the AGEP criteria would follow a different pattern when the disease is triggered by this drug. A PubMed search helped retrieve all terbinafine-induced AGEP case reports. AGEP-specific Sideroff criteria were analysed in terbinafine-induced cases and compared to other trigger causes. CONCLUSIONS: When the AGEP causative drug was terbinafine, a delay in recovery was observed, compared to the existing AGEP criteria when other causes are considered. Terbinafine frequently leads to delayed resolution AGEP probably due to the presence of the drug in the skin for several weeks after exposure, even after discontinuation, and the disease severity may be potentialised by additional factors such as concomitant viral infections or vaccination.

Coexistence of onychomycosis and nail psoriasis and its correlation with systemic treatment.

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).

Quantification of histopathological changes in patients with psoriasis before and after phototherapy.

BACKGROUND: One of the most used resources for the treatment of psoriasis is ultraviolet radiation (UV) with psoralens (PUVA) and narrow-band UV (UVB-NB 311-312 nm). Although many researchers have assessed the histopathological effects of this therapy modality, none used a morphological classification system specific to psoriasis. PURPOSE: To assess the clinical and histopathological response in the phototherapy treatment of plaque psoriasis with PUVA and UVB-NB with use of PASI and TROZAK. METHODS: Histopathological changes of plaque psoriasis were quantified with help of the grading system for psoriasis-Trozak in 20 patients of both sexes, before and after 32 PUVA phototherapy sessions (10 patients-GPUVA) and UVB-NB (10 patients-GUVB-NB). The severity and extension of psoriasis was evaluated through PASI. The slides stained with hematoxylin and eosin were scanned in an Aperio CS2 scanner (Leica Biosystems) and evaluated through the software ImageScopeTM (Aperio Technologies). Statistical analysis was performed with the use of the program SPSS 22.0, with application of the Wilcoxon and Mann-Whitney tests. RESULTS: All patients presented improvement in psoriatic plaques with decrease in PASI after treatment (P < 0.01) and significant reduction in histopathological changes in psoriasis from 15.4 ± 1.7 to 3.7 ± 3.2 (P < 0.01) in group GPUVA and from 13.2 ± 1.7 to 4.9 ± 5.2 (P < 0,01) in group GUVB-NB. CONCLUSIONS: Phototherapy, regardless of type, is an effective treatment for moderate and severe psoriasis, with possibility of being quantified clinically by PASI and histopathologically by Trozak.

History of Seborrheic Dermatitis: Conceptual and Clinico-Pathologic Evolution.

Seborrheic dermatitis is an inflammatory and chronic disease with a high incidence and prevalence (1% to 3% in the general population, 3% to 5% in young adults, and 40% to 80% in HIV-positive individuals). Although the condition was first described in 1887, its clinical aspects and clinical forms have still not been well individualized, nor has its etiopathogenesis been fully elucidated. The disease, despite having clinical features similar to dermatitis, does not have the same histopathologic features or the same progressive clinical behavior. This contribution reviews the history of seborrheic dermatitis.

Carboxymethyl Cellulose, Trichloroacetic Acid, and Unna Boot for Healing Venous Ulcers: A Comparative Study of Their Efficacy and Socioeconomic Impact.

Chronic ulcers are defined as a breakdown of the long-term cutaneous barrier or frequent recurrence of breakdowns. Dressings are a form of treatment and, in view of the variety and high cost of the products on the market, three agents were selected for this investigation, regarding their efficacy and cost/benefit ratio. The objective of the investigation was to evaluate and compare the efficacy, costs, and benefits of carboxymethylcellulose in paste at 20% (CMC 20%), trichloroacetic acid at 90% (TCA 90%), and Unna boot for treatment of chronic venous ulcers. Three groups of 30 patients each were chosen randomly for ambulatory treatment with TCA 90% (G1), CMC 20% (G2), and Unna boot (G3). The evolution of the cicatricial process of each group separately and between groups was analyzed with measurement of the lesion areas in square centimeters (cm2) and observation of the amount of exudate from observation of the photographic record, until their healing, in the maximum period of 20 weeks. A significant reduction of lesion areas in all groups was observed (P=.0001), with a median reduction of 7.6 cm2 (38.1%) for G1, 3.9 cm2 (38.8%) for G2, and 16.2 cm2 (77.8%) for G3. There was a significant difference in the absolute delta of the lesion areas (P=.0001) of the groups. The three types of treatments promoted effective improvement, with acquisition and utilization of all three products in the public health services being recommended.

Alopecia Areata-Part III: Prognosis and Treatment.

The prognosis of alopecia areata is better in cases with single and small lesions, and the variability of the extension of the disease is one of the criteria for the choice of treatment modality. Several medications have been described in the literature for the treatment of alopecia areata, including corticosteroids, minoxidil, and diphencyprone. The authors review treatments for alopecia areata.

Dermatomyositis--Part 1: Definition, Epidemiology, Etiology and Pathogenesis, and Clinics.

Dermatomyositis is an inflammatory autoimmune disorder that affects the skin, muscles, and blood vessels. The prevailing clinical manifestations are intense erythema, typically around the eyes and dorsum of the hands, accompanied by proximal muscle weakness. There is one clinical form, called amyopathic dermatomyositis, which lacks muscular symptoms and laboratory evidence of muscle damage.

Dermatomyositis-Part 2: Diagnosis, Association With Malignancy, and Treatment.

In this second part of the series on dermatomyositis, the diagnosis and its criteria with review of autoantibodies, capillaroscopy, imaging exams, histopathology, muscle biopsy, electroneuromyography, and muscular enzymes will be assessed. The association with malignancy, since it is described as paraneoplasic, will be discussed. The different therapeutic options for this disease will also be reported, including for dystrophic calcification, a rare and late complication of dermatomyositis.

Correlation Between Severity Index and Quality of Life Index in Patients With Psoriasis Assessed Before and After Phototherapy.

Psoriasis is a common disease whose impact on the life of patients is well documented. The authors investigated the correlation between clinical severity and quality of life in patients with psoriasis before and after phototherapy. Twenty men and women were assessed before and after 32 phototherapy sessions, employing the Dermatology Life Quality Index (DLQI) questionnaire and the Psoriasis Area Severity Index (PASI). A positive and moderate correlation was found between PASI and DLQI after phototherapy (r=0.48, P=.03). This result was not observed before treatment (r=0.13, P=.57). The clinical signs reduction obtained with phototherapy was associated with clinical improvement in patient quality of life. The negative findings for the pretreatment phase suggest a possible acceptance by patients through strategies establishment to improve the handling of the disease, which has a chronic character, and change in the disease's perception after therapy.

Psoriasiform Eruption Secondary to the Use of Adalimumab.

Induced psoriasiform eruption, especially by anti-tumor necrosis factor alpha, was a rather rare event but nowadays cases are increasing because of its prescription for many different diseases. There are several clinical forms; one example is the pustulosis form presented in this case report.

Alopecia areata--Part I: Background .

Alopecia areata is a trichosis characterized by loss of hair, with the abrupt onset of round or oval, nonscarring, flat, single or multiple areas of alopecia lesions, which can coalesce. Several hypotheses have been raised to explain its etiology, with autoimmunity being accepted until today, along with genetic factors.

Alopecia areata--Part II: diagnosis and pathology.

Alopecia areata is characterized by the abrupt appearance of round or oval, non-scarring, flat, single or multiple areas of alopecia, which may coalesce forming large patches of alopecia. The diagnosis is usually clinical but there are important differentials and dermatopathology may help in this definition.

Comparison of the effect of diode laser versus intense pulsed light in axillary hair removal.

BACKGROUND: Devices such as diode laser and intense pulsed light (IPL) are in constant development aiming at permanent hair removal, but there are few comparative studies between these technologies. OBJECTIVE: The objective was to comparatively assess axillary hair removal performed by diode laser and IPL and to obtain parameters of referred pain and evolution response for each method. MATERIALS AND METHODS: A comparative prospective, double-blind, and randomized study of axillary hair removal performed by the diode laser and IPL was conducted in 21 females. Six sessions were held with application of the diode laser in one axilla and the IPL in the other, with intervals of 30 days and follow-up of 6 months after the last session. Clinical photographs and digital dermoscopy for hair counts in predefined and fixed fields of the treated areas were performed before, 2 weeks after the sixth session, and 6 months after the end of treatment. A questionnaire to assess the pain was applied. RESULTS: The number of hair shafts was significantly reduced with the diode laser and IPL. The diode laser was more effective, although more painful than the IPL. No serious, adverse, or permanent effects were observed with both technologies. CONCLUSION: Both diode laser and the IPL are effective, safe, and able to produce lasting results in axillary hair removal.

Monkeypox: What the Dermatologist Needs to Know.

Monkeypox, an endemic disease in some African countries, has provoked public health activeness on a global scale that even the World Health Organization (WHO), invoking international health regulations, declared it a public health emergency of international concern (PHEIC). The WHO called attention of member states to exert maximum surveillance over the disease, its patients, and contact persons in order to standardize control measures. A need was directed to provide complete knowledge about the disease, allowing the administration of prior diagnoses as well as isolation and more effective epidemiologic control measures. An updated review on monkeypox emphasized upon having the fundamental aspects of the lesions caused by the disease, and appropriate management of patients upon clinical and epidemiologic evaluation.

Recalcitrant Sterile Abscesses by Volux®: A New Therapeutic Approach.

The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux®, the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux® who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors. (SKINmed. 2023;21:27-33).

Brooke-Spiegler Syndrome with Parotid Gland Involvement.

A 60-year-old black man, working in construction sector, was referred to dermatology clinic for having multiple hardened and asymptomatic tumors on the scalp, face, and trunk for more than 40 years. There was a progressive increase in the number and size of lesions, causing significant aesthetic and functional impairment. In his family history, a son had numerous normochromic papules on the centrofacial region with a diagnosis of multiple trichoepithelioma. The deceased mother of our patient presented lesions similar to those of her grandson but without a confirmatory diagnosis. (SKINmed. 2023;21:47-50).

Rationale and Guidelines for the Use of Hyaluronidase: A Practical Guide for Complications Caused by Hyaluronic Acid.

The use of enzyme hyaluronidase to treat the complications of different brands of hyaluronic acid (HA) dermal fillers is increasing in the same proportion as the number of nonsurgical cosmetic procedures. Guidelines for diagnosing and treating complications remain controversial and are primarily based on anecdotal reports and small case series. We proposed approaching HA-related complications based on our clinical research and observations of treating more than 200 patients and providing a practical guide for the thoughtful use of hyaluronidase according to adverse events. Standardization of hyaluronidase dose and concentration is beneficial for better outcomes and future comparative analyses of the results of this treatment worldwide. The use of hyaluronidase is increasing for the reversal of the clinical manifestations of complications caused by HA fillers, although a consensus is lacking. We propose using different doses and concentrations of hyaluronidase to focus on selected anatomic areas considering properties of the product and pathogenesis of each complication.
