RESUMEN

BACKGROUND: Bullous pemphigoid (BP) is an acquired subepidermal autoimmune blistering disease in which there are humoral and cellular responses against the BP180 and BP230 antigens. Dipeptidyl peptidase (DPP)-4 inhibitors enhance endogenous glucagon peptide-1 and glucose-dependent insulinotropic polypeptide secretion with food intake, which leads to insulin secretion, as well as to the reduction of glucagon secretion. Recently, several cases of DPP-4 inhibitor-associated BP have been reported. OBJECTIVES: To report 3 cases of DPP-4 inhibitor-associated BP, one of which is due to linagliptin use, as well as to review all currently published cases of DPP-4 inhibitor-associated BP. CASE REPORTS: Three patients diagnosed with BP at our department showed a clear temporal relationship between the introduction of DPP-4 for the treatment of diabetes and the onset of BP. One case was due to linagliptin use, while the other 2 cases were due to an association with vildagliptin-metformin use. CONCLUSIONS: This is the first report of linagliptin-associated BP. Furthermore, 2 other cases of vildagliptin-associated BP are reported.

RESUMEN

BACKGROUND: For years, phototherapy has been used in a wide range of skin diseases, which is unsurprising as skin is the anatomical feature most directly exposed to light, especially in psoriasis. Although the role of light therapy has been replaced by different therapeutic modalities in recent years, this treatment is now an established option for many skin diseases. OBJECTIVES: The aim was to characterize the patient population that had received the aforementioned treatment in the Virgen Macarena Health Area in Seville (Spain) between June 1985 and October 2011. METHODS: We have designed a descriptive study with a univariate analysis covering 443 treatments with light therapy, all administered to the same number of patients suffering from psoriasis. RESULTS: 79.15% of patients were discharged due to improvement or healing, while the 20.85% were discharged due to other reasons. The average total accumulative dose was 131.53 J/cm2. We do not detected an increase in proportion in patients for develop NMSK after light therapy treatment. CONCLUSIONS: We consider that phototherapy is still an effective and efficient treatment that will have to be reconsidered in the current macroeconomic context.

RESUMEN

BACKGROUND: Dermatitis artefacta (DA) consists of self-inflicted skin lesions that the patient denies having produced. OBJECTIVES: To conduct a single-center retrospective clinical review of children and adolescents diagnosed with DA. METHODS: From 1976 to 2006, data were collected on children diagnosed with DA who were seen in the Department of Dermatology in our hospital. Clinical and epidemiologic features are described. Forty-four children (mean age 12.9 yrs) were selected, representing 21.9% of the total patients with DA recorded (n = 201) during this period. RESULTS: The most frequent clinical forms were excoriations (16 [36.4%]) and ulcers (10 [22.7%]), followed by blisters (7 [15.9%]), burns (3 [6.8%]), contact dermatitis (3 [6.8%]), hematomas (2 [4.5%]), panniculitis (1 [2.3%]), cheilitis (1 [2.3%]), and hyperpigmentation (1 [2.3%]). Sixteen were located exclusively on the face and neck, whereas 28 also had other locations (upper limbs, n = 10; lower limbs, n = 9; thorax, n = 5; abdomen, n = 4). Cutaneous lesions were treated with occlusive bandages using zinc paste or a plaster splint when necessary. CONCLUSION: To our knowledge, this is the largest reported series of DA in childhood. This complicated psychodermatologic condition requires correct diagnosis, appropriate management, and psychiatric assessment.

RESUMEN

While treatment of keloids and hypertrophic scars normally shows modest results, we found that treatment with bleomycin was more promising. The present study was divided into two parts. In the first part the aim was to show the results using a combination of bleomycin and triamcinolone acetonide per cm2 (BTA). In the second part the objective was to determine the response to both drugs in large keloids that were divided into 1 cm2 squares, treating each square with the dose previously used. In the first part of the study, the clinical response of 37 keloids ranging from 0.3 to 1.8 cm2 treated with BTA were followed up over a period of 1- 2 years. 0.375 IU bleomycin and 4 mg triamcinolone acetonide were injected every 3 months. In the second part of the study we reviewed the clinical response in six patients with large keloids. The monthly dose administered never exceeded 3 IU of bleomycin. The first study showed 36 keloids (97.29%) softening after the first dose. In the second study, 5 showed different responses (the response was complete in the four smaller keloids). The largest keloid needed 9 doses to achieve an improvement of 70%. In conclusion, combined treatment with 0.375 IU of bleomycin and 4mg of triamcinolone acetonide to 1 cm2 was considered to be an acceptable procedure for the treatment of keloids. The best results were obtained in keloids over 1 cm2 or when divided into 1 cm2 square areas. Larger series need to be performed in order to confirm these results..

Enquanto normalmente o tratamento de queloides e cicatrizes hipertróficas mostra resultados moderados, o tratamento com bleomicina revelou resultados mais promissores. Este estudo foi dividido em duas partes. Na primeira parte, o objetivo foi mostrar os resultados da utilização de uma combinação de bleomicina e acetonido de triancinolona por cm2 (BAT). Na segunda parte, o objetivo foi determinar a resposta aos dois medicamentos em queloides grandes, que foram divididos em quadrados de 1 cm2, tratando cada quadrado com a dose utilizada anteriormente. Na primeira parte do estudo, a resposta clínica de 37 queloides de 0,3 to 1,8 cm2 tratados com BAT foi monitorada por um período de 1 a 2 anos. Injeções de 0,375 UI de bleomicina e 4 mg de acetonido de triancinolona foram aplicadas a cada 3 meses. Na segunda parte do estudo, revisamos a resposta clínica em 6 pacientes com queloides grandes. A dose mensal administrada nunca excedeu 3 UI de bleomicina. O primeiro estudo mostrou que 36 queloides (97,29%) amoleceram após a primeira dose. No segundo estudo, 5 mostraram diferentes respostas (a resposta foi completa nos quatro queloides menores). O queloide maior necessitou de 9 doses para apresentar melhora de 70%. Concluindo, o tratamento combinado com 0,375 UI de bleomicina e 4 mg de acetonido de triancinolona por cm2foi considerado um procedimento aceitável para o tratamento de queloides. Os melhores resultados foram obtidos em queloides com mais de 1 cm2 ou divididos em áreas de 1cm2. Estudos mais amplos deveriam ser realizados, para confirmar esses resultados.

RESUMEN

BACKGROUND: Soft tissue augmentation is one of the most frequent techniques in cosmetic dermatology. Nowadays, there are a high number of available materials. Nonanimal hyaluronic acid (HA) is one of most useful fillers for lip augmentation and for treating nasolabial folds, marionette lines, and the dynamic wrinkles of the upper face. OBJECTIVE: To evaluate the type and management of undesirable effects of nonanimal reticulated or stabilized HA observed in our cosmetic unit in the past 3 years. MATERIALS AND METHODS: The consecutive patients using HA attending to our clinic in the past 3 years were divided into 3 categories, according to the time of presentation of the adverse reactions: immediate, early, and late-onset complications. All patients were treated. RESULTS: Twenty-three patients presented to our clinic complaining of complications after soft tissue augmentation with HA. Ten patients presented immediate-onset complications, 8 showed early-onset complications, and 5 cases complaint of late-onset complications. Treatment of the first group consisted of hyaluronidase injection, massage, and topical antibiotics. Early- and late-onset complications were treated with intralesional triamcinolone acetonide. All patients improved, with the exception of a woman with recurrent granulomas. CONCLUSION: Generally, undesirable effects of HA (immediate, early, or late onset) are not frequent, and when present, they improve if treated properly. Physicians need to be aware of these possible adverse events in order to establish proper treatment and prevent scarring or other sequelae.

RESUMEN

INTRODUCTION: Frontal fibrosing alopecia (FFA) in an entity characterized by the recession of the frontotemporal hairline (FTHL) with alopecic scarring change. In recent years there are numerous articles discussing the usefulness of dermoscopy for the clinical diagnosis of different types of scarring alopecia. MATERIALS AND METHODS: We value 79 patients diagnosed with FFA, evaluating some trichoscopical findings described as typical for FFA: Absence of follicular opening, follicular hyperkeratosis, follicular plugs and erythema. RESULTS: In a population of 79 women, 100% showed no follicular opening, 72.1% follicular hyperkeratosis, 66.3% perifollicular erythema and 44.8% follicular plugs. Thus, 100% of patients had at least one of the dermoscopic elements described as suggestive of FFA, 53% two of them, 45% three and 27%, all those elements. Perifollicular erythema was present in 95% of cases in which the disease was active. CONCLUSIONS: We consider that the presence of perifollicular erythema will be a direct marker of FFA activity.

RESUMEN

BACKGROUND: The efficacy of etanercept in the treatment of psoriasis has been demonstrated in several clinical trials, but information regarding results derived from prospective observational studies in clinical practice is scarce. OBJECTIVES: To evaluate the efficacy and safety of etanercept administration according to routine clinical use in moderate-to-severe plaque psoriasis. MATERIALS AND METHODS: Postauthorization, prospective study, carried out at 59 dermatology units in Spain. Patients diagnosed with moderate-to-severe plaque psoriasis received etanercept during a 12-month period. RESULTS: Altogether, 444 patients were enrolled. Overall, 325 patients (73.2%) initiated etanercept treatment at a dose of 50 mg twice weekly; 96 patients (21.6%) received etanercept as a continuous regimen for the entire study period, and 348 patients (79.4%) an intermittent regimen. Among these, 185 patients (41.6% overall) received one course of treatment, stopped at various study points and did not restart etanercept treatment, whereas the remaining 163 patients (36.7% overall) stopped etanercept treatment, lost response, relapsed and were retreated. Most patients who interrupted etanercept treatment did so at month 6. Altogether, 79.7% of patients completed the study period. Etanercept treatment resulted in significant improvement in disease activity. A Psoriasis Area and Severity Index (PASI) 75 response was achieved by 76.1% of patients at month 6. Out of 252 adverse events reported, 31 were considered severe. Three possibly treatment-related malignancies were detected during the study. No opportunistic infections, tuberculosis or demyelinating events were reported. CONCLUSION: The PASI 75 response rate at month 6 in this observational, naturalistic study is similar to those observed in recent published trials with etanercept, and within the range of those reported for other marketed biologicals.
