Evolução histórica dos Anais Brasileiros de Dermatologia

Nesta edição especial para o centenário da Sociedade Brasileira de Dermatologia, os autores fazem uma retrospectiva da dermatologia brasileira impressa, desde os primórdios, evidenciando a dermatologia descritiva com ricas discussões, ilustrações e propagandas de medicações muito utilizadas na época, como o bismuto no tratamento da sífilis, antes da descoberta da penicilina. Esta revisão chega até os dias atuais, quando as publicações nos Anais Brasileiros de Dermatologia entraram na era da modernidade eletrônica, científica e também de layout.

Prevalence of depression and anxiety disorders in hospitalized patients at the dermatology clinical ward of a university hospital

BACKGROUND: The objective of this study was to estimate the prevalence of depression and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo, Brazil. OBJECTIVE: To assess the prevalence of mood and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo. METHOD: A total of 75 patients, men and women, aged between 18 and 76 years, took part in the research. The study employed a descriptive, cross sectional and correlational method. The data was collected by means of a social demographic questionnaire and the PRIME-MD. RESULTS: It was found that 45.3 percent of the subjects presented with depressive symptoms, and 52 percent presented with symptoms of anxiety and that this survey showed moderate and high significant correlations (p<0,01; r= 0,616) for depression and anxiety. CONCLUSION: These facts could evidence the relationship between physical and psyche, just as the literature presents.

Photodynamic therapy in actinic cheilitis: clinical and anatomopathological evaluation of 19 patients

BACKGROUND: Actinic cheilitis, a common disease caused by chronic solar exposure and tobacco use, is considered a premalignant lesion with potential to develop into squamous cell carcinoma. Some of the available treatments are invasive, have unaesthetic results and require multiple sessions. OBJECTIVE: To assess the efficacy of a therapy and its cosmetic results. METHODS: In this uncontrolled clinical trial a single photodynamic therapy (PDT) session using 16% methyl-aminolevulinate was performed on actinic cheilitis of the lower lip. A standardized questionnaire was applied in order to assess the clinical improvement from the patients' point of view and the satisfaction with the treatment. Anatomopathological evaluation was performed before the treatment and two months afterwards. RESULTS: The sample was composed of 19 patients (10 males and 9 females), phototypes I to III, with average age of 62 years. Main adverse effects were: sudden pain, scabs, herpes flare-up, and edema. The average score of pain during the procedure was 5,8+2,9. At the final assessment the patients reported improvement of 80% and satisfaction of 85% (p<0.01). Anatomopathological analysis showed a significant decrease of dysplasia (p=0.03) in spite of its presence in 84% of cases. There was no significant correlation between the level of dysplasia with either the subjective impression of clinical improvement (p=0.82) or with the patients' final satisfaction (p=0.96). CONCLUSION: PDT is effective in the treatment of actinic cheilitis, but it is associated with a significant level of pain. Due to the persistence of dysplasia, more research needs to be done in order to define the ideal number of sessions for the effective treatment of these lesions.

Pain in photodynamic therapy: mechanism of action and management strategies

Photodynamic therapy involves administration of a photosensitizing drug and its subsequent activation by irradiation with a light source at wavelengths matching the absorption spectrum of the photosensitizer. In many countries around the world, topical photodynamic therapy has been approved for treatment of cutaneous oncologic conditions such as actinic keratosis, Bowen's disease, and superficial basal cell carcinoma. Multicenter, randomized, controlled studies have confirmed its efficacy and superior cosmetic outcomes compared to conventional therapies. Nevertheless, this therapeutic method presents some adverse effects, such as erythema, edema, pigmentation, pustules, and pain. There is no doubt that pain is the most severe of the adverse effects, being sometimes responsible for definitive treatment interruption. The pain mechanism has not yet been fully understood, which makes complete pain control a challenge to be conquered. In spite of that, this literature review presents some useful pain management strategies as well as the most important pain-related factors in photodynamic therapy.

The vegetal biomembrane in the healing of chronic venous ulcers

BACKGROUND: The vegetal biomembrane has been used to treat cutaneous ulcers. OBJECTIVES: To assess the role of the vegetal biomembrane on the chronic venous ulcers treatment compared to treatment with collagenase cream. METHODS: Fourteen patients were selected to be treated with vegetal biomembrane and 7 with Fibrase®(CONTROL), followed clinically and photographically by the Wound Healing Index by ImageJ during 120 days and biopsied on the 1st and 30th days for histological examination. RESULTS: The vegetal biomembrane was better in promoting healing of the ulcers, especially on the inflammatory phase, confirmed by abundant exudation and wound debridement than the CONTROL group, on the 30th day. There was a greater tendency to angiogenesis followed by re-epithelialization with highest wound healing index on the 90th and 120th days. CONCLUSION: A combined analysis of clinical and histopathological findings suggests that the vegetal biomembrane acted as a factor inducing wound healing, especially on the inflammatory phase, confirmed by abundant exudation of the lesions promoting the transformation of the microenvironment of the chronic venous ulcers, and also stimulating angiogenesis and subsequent re-epithelialization.

Localized scleroderma: assessment of the therapeutic response to phototherapy

BACKGROUND: Scleroderma is a chronic autoimmune disease characterized by progressive connective tissue sclerosis and microcirculatory changes. Localized scleroderma is considered a limited disease. However, in some cases atrophic and deforming lesions may be observed that hinder the normal development. Literature reports indicate phototherapy as a therapeutic modality with favorable response in cutaneous forms of scleroderma. OBJECTIVES: This study had the purpose of assessing the phototherapy treatment for localized scleroderma. METHODS: Patients with localized scleroderma were selected for phototherapy treatment. They were classified according to the type of localized scleroderma and evolutive stage of the lesions. Clinical examination and skin ultrasound were used to demonstrate the results thus obtained. RESULTS: Some clinical improvement was observed after an average of 10 phototherapeutic sessions. All skin lesions were softer at clinical palpation with scores reduction upon pre and post treatment comparison. The ultrasound showed that most of the assessed lesions presented a decrease in dermal thickness, and only five maintained their previous measure. Treatment response was similar regardless of the type of phototherapeutic treatment employed. CONCLUSIONS: The proposed treatment was effective for all lesions, regardless of the phototherapeutic modality employed. The improvement was observed in all treated skin lesions and confirmed by clinical evaluation and skin ultrasound.

Papillary atrophy of the tongue and nutritional status of hospitalized alcoholics

BACKGROUND: Atrophy of the papillae, mucosa, and dorsum of the tongue are considered classical signs of nutritional deficiencies. OBJECTIVE: To assess the nutritional status of hospitalized alcoholics with or without papillary atrophy of the tongue. METHODS: This study was performed with 21 hospitalized alcoholics divided into Atrophic Glossitis Group (n=13) and Normal Tongue Group (n=8). Healthy, non-alcoholic volunteers composed the Control Group (n=8). Anthropometry and bioelectric impedance were performed, and serum vitamins A, E, and B12 were determined. RESULTS: There were no statistical differences in relation to age (46.7±8.7 vs. 46.8±15.8 years) or gender (92.3% vs. 87.5% male), respectively. Control Group volunteers were also paired in relation to age (47.5±3.1 years) and male predominance (62.5%). In relation to hospitalized alcoholics without atrophic lesions of the tongue and Control Group, patients with papillary atrophy showed lower BMI (18.6 ± 2,5 vs 23.8 ± 3.5 vs 26.7 ± 3,6 kg/m² ) and body fat content 7.6 ± 3.5 vs 13.3 ± 6.5 vs 19.5 ± 4,9 kg). When compared with the Control Group, alcoholic patients with or without papillary atrophy of the tongue showed lower values of red blood cells (10.8 ± 2.2 vs 11.8 ± 2.2 vs 14.5 ± 1,6g/dL) and albumin (3.6 ± 0.9 vs 3.6 ± 0.8 vs 4.4 ± 0.2g/dL). The seric levels of vitamins A, E, and B12 were similar amongst the groups. CONCLUSION: Hospitalized alcoholics with papillary atrophy of the tongue had lower BMI and fat body stores than controls, without associated hypovitaminosis.

Association of acanthosis nigricans and skin tags with insulin resistance

Insulin resistance is a metabolic disorder in which target cells fail to respond to normal levels of circulating insulin. Insulin resistance has been associated with presence of acanthosis nigricans and acrochordons. It is known that early diagnosis and early initial treatment are of paramount importance to prevent a series of future complications. These dermatoses may represent an easily identifiable sign of insulin resistance and non-insulin-dependent diabetes.

Quality of life of patients with paucibacillary leprosy

BACKGROUND: Leprosy, an infectious disease caused by Mycobacterium leprae, can affect the skin and the peripheral nervous system and, depending on the level of involvement, it can lead to severe deformities. Leprosy is classified into two major groups: paucibacillary (up to five lesions) and multibacillary (more than five lesions). The deformities that appear during the progress of the disease can affect the quality of life. OBJECTIVE: To assess quality of life of patients with paucibacillary leprosy diagnosed and treated early in the outpatients' clinic. METHODS: The Dermatology Life Quality Index questionnaire and ShortForm36 were applied to 49 outpatients undergoing treatment at the Leprosy Multidisciplinary Group of the Hospital das Clínicas of the Faculdade de Medicina of the Universidade de São Paulo. RESULTS: The majority of the patients (63%) did not show impairment of the quality of life, according to the results obtained by the Dermatology Life Quality Index questionnaire. In the questionnaire Short Form-36, the scores assessed showed slight impairment of the quality of life. CONCLUSION: On this study, we can conclude that this group of patients, with paucibacillary leprosy, did not show important impairment of the quality of life. Therefore we can conclude that the earlier the diagnosis and the treatment the lesser the influence on the quality of life.

Drug reaction with Eosinophilia and Systemic Symptoms (DRESS) / Drug-induced Hypersensitivity Syndrome (DIHS): a review of current concepts

The Drug Reaction with Eosinophilia and Systemic Symptoms syndrome, also known as Drug Induced Hypersensitivity Syndrome presents clinically as an extensive mucocutaneous rash, accompanied by fever, lymphadenopathy, hepatitis, hematologic abnormalities with eosinophilia and atypical lymphocytes, and may involve other organs with eosinophilic infiltration, causing damage to several systems, especially to the kidneys, heart, lungs, and pancreas. Recognition of this syndrome is of paramount importance, since the mortality rate is about 10% to 20%, and a specific therapy may be necessary. The pathogenesis is related to specific drugs, especially the aromatic anticonvulsants, altered immune response, sequential reactivation of herpes virus and association with HLA alleles. Early recognition of the syndrome and withdrawal of the offending drug are the most important and essential steps in the treatment of affected patients. Corticosteroids are the basis of the treatment of the syndrome, which may be associated with intravenous immunoglobulin and, in selected cases, Ganciclovir. The article reviews the current concepts involving this important manifestation of adverse drug reaction.

Case for diagnosis

Porokeratosis is a primary keratinizing disorder of unknown etiology. This disorder is characterized by the presence of centrifugally enlarging hyperkeratotic plaques, associated with the histopathological hallmark of cornoid lamellae. Genital porokeratosis is extremely rare. No more than thirty cases have been reported in the literature, including only one case of linear porokeratosis confined to the genital area. This case report describes a patient with genital linear porokeratosis, who was successfully treated with cryotherapy. Over two years of follow-up, the lesion improved and there was no evidence of recurrence or signs of malignant transformation. Nevertheless, there is a need for long-term follow-up data on recurrence and malignant transformation.

Case for diagnosis

Infantile digital fibromatosis or Reye's tumor is a benign fibroproliferative tumor, the etiopathogenesis of which has yet to be fully clarified. It typically presents at birth or in the first year of life and is characterized by a firm, flesh colored or erythematous nodule or nodules located on the digits. These lesions tend to regress spontaneously.

Brazilian blood donation eligibility criteria for dermatologic patients

A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved), personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Discussion: Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods.

Acne fulminans successfully treated with prednisone and dapsone

Acne fulminans is a rare condition and the most severe form of acne. It involves the sudden onset of febrile and multisystemic symptoms, with poor response to ordinary therapy in patients who previously had mild to moderate acne. It is characterized by hemorrhagic ulcerative crusting lesions on the face, chest and upper back. The authors report a case of acne fulminans that was successfully treated with oral prednisone and dapsone.
