- Adult Tinea Capitis and Tinea Barbae in a Tertiary Portuguese Hospital: a 11-Year AuditPublication . Duarte, B; Galhardas, C; Cabete, JAdult tinea capitis and tinea barbae are nowadays considered uncommon in developed countries. Despite their potential for morbidity and healthcare costs, few series have attempted to characterise these infectious disorders. We conducted a cross-sectional study to analyse the epidemiological, clinical and mycological characteristics of adult tinea capitis and tinea barbae of a large tertiary centre in Southern Europe. All adult patients with a mycological-confirmed tinea capitis or barbae over a 11-year period (January 2008 to December 2018) were considered for the analysis. Concerning tinea capitis, 860 culture-confirmed diagnoses were made during this 11-year period, of which only 15 (1.5%) occurred in adults (15 patients). A disproportionately high number of patients were female and immunocompromised. Microsporum audouinii (20%) and Trichophyton rubrum (20%) were the most common isolates. Half of the cases were initially misdiagnosed. Regarding tinea barbae, 7 cases were diagnosed over this time period. Overuse of topical steroids was widespread in this population. Trichophyton rubrum was the infectious agent in all cases. Initial misdiagnosis was very common (43%). Adult tinea capitis and tinea barbae can still be observed in contemporary practice and remain a public health concern, with the immunosuppressed patient being particularly affected. Initial misdiagnosis is a common occurrence. Anthropophilic fungi are now the most common aetiologic agents of these infections, and they will probably continue to do so as the large urban centres expand peripherally. Awareness for this diagnosis is necessary to prevent unwarranted morbidity and costs.
- Aneurismas Venosos Superficiais. Casuística, Casos Clínicos e Revisão da LiteraturaPublication . Neves, J; Sousa, V; Cavadas, D; Cabete, J; Formiga, AOs aneurismas venosos são uma entidade patológica pouco frequente, embora a sua deteção possa vir a aumentar como consequência da crescente utilização do ecodoppler como meio complementar de diagnóstico. Podem apresentar-se, clinicamente, como massas dos tecidos moles, ocasionalmente simulando hérnia ou adenopatia da região inguinal, particularmente os que surgem no sistema venoso superficial dos membros inferiores. Estão descritos na literatura casos de aneurismas venosos superficiais associados a tromboembolismo pulmonar. Considerando a potencial morbimortalidade, a abordagem terapêutica é cirúrgica na maioria dos casos. Os autores apresentam a sua casuística de aneurismas venosos superficiais num período de 20 anos, três casos clínicos mais exemplificativos e fazem uma revisão da literatura.
- Anti-Tumor Necrosis Factor Alpha-Induced Drug Eruptions: One Patient, More Than a PatternPublication . Cabete, J; Lestre, S; João, A; Ferreira, A; Serrão, VBackground: Tumor necrosis factor alpha (TNFα) antagonists are effective in treating several immune-inflammatory diseases, including psoriasis and inflammatory bowel disease. The paradoxical and unpredictable induction of psoriasis and psoriasiform skin lesions is a recognized adverse event, although of unclear aetiology. However, histological analysis of these eruptions remains insufficient, yet suggesting that some might constitute a new pattern of adverse drug reaction, rather than true psoriasis. Case report: The authors report the case of a 43-year-old woman with severe recalcitrant Crohn disease who started treatment with infliximab. There was also a personal history of mild plaque psoriasis without clinical expression for the past eight years. She developed a heterogeneous cutaneous eruption of psoriasiform morphology with pustules and crusts after the third infliximab infusion. The histopathological diagnosis was of a Sweet-like dermatosis. The patient was successfully treated with cyclosporine in association with both topical corticosteroid and vitamin D3 analogue. Three weeks after switching to adalimumab a new psoriasiform eruption was observed, histologically compatible with a psoriasiform drug eruption. Despite this, and considering the beneficial effect on the inflammatory bowel disease, it was decided to maintain treatment with adalimumab and to treat through with topicals, with progressive control of skin disease. Discussion: Not much is known about the pathogenesis of psoriasiform eruptions induced by biological therapies, but genetic predisposition and Koebner phenomenon may contribute to it. Histopathology can add new facets to the comprehension of psoriasiform reactions. In fact, histopathologic patterns of such skin lesions appear to be varied, in a clear asymmetry with clinical findings. Conclusion: The sequential identification in the same patient of two clinical and histopathologic patterns of drug reaction to TNFα antagonists is rare. Additionally, to the authors’ knowledge, there is only one other description in literature of a TNFα antagonist-induced Sweet-like dermatosis, emphasizing the singularity of this case report.
- Blastic Plasmacytoid Dendritic Cell NeoplasmPublication . Lencastre, A; Farinha, P; Cabete, J; Ferreira, G; João, A; Lestre, SBlastic plasmacytoid dendritic cell neoplasm is a rare and aggressive hematodermic neoplasia with frequent cutaneous involvement and leukemic dissemination. We report the case of a 76-year-old man with a 2 month history of violaceous nodules and a tumor with stony consistency, located on the head, and mandibular, cervical and supraclavicular lymphadenopathies. Multiple thoracic and abdominal adenopathies were identified on computerized tomography. Flow cytometry analysis of the skin, lymph node and bone marrow biopsies demonstrated the presence of plasmocytoid dendritic cell neoplastic precursor cells (CD4+, CD45+, CD56+ and CD123+ phenotype). After initial clinical and laboratorial complete remission with chemotherapy, the patient died due to relapse of the disease associated with the appearance of a cervical mass with medullary compromise.
- Caracterização do Perfil Microbiológico e de Sensibilidade Antimicrobiana dos Microrganismos Isolados em Úlceras Diabéticas de Doentes de um Hospital PortuguêsPublication . Cabete, J; Moniz, L; Pinto, M; Neves, J; Alves, CP
- Case for DiagnosisPublication . Lencastre, A; Cabete, J; Apetato, MAn 83 year-old man was observed for an 8 year-long pruritic, erythematous plaque of the left axilla. He had been continuously medicated with topical antifungals and steroids with occasional symptomatic relief, but with disease progression. After a clinical and histological diagnosis of Extramammary Paget's Disease, a total excision with wide margins was performed. He remains disease-free 12 months after surgery. We report this rare presentation of Extramammary Paget's Disease on a male patient.
- Conscious Sedation with Inhaled 50% Nitrous Oxide/Oxygen Premix in Photodynamic Therapy Sessions for Vulvar Lichen Sclerosus TreatmentPublication . Cabete, J; Lestre, S; Campos, SPhotodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.
- Conservative Treatment of Chondrodermatitis Nodularis Chronica Helicis with Topical NitroglycerinPublication . Cabete, J; Lencastre, A; Paiva Lopes, MJ; Lestre, S; Serrão, VBackground: Chondrodermatitis nodularis chronica helicis (CNCH) is a benign, painful, indurated inflammatory nodule arising on the pinna. Different treatment modalities have been used with varying efficacy rates. Despite lower efficacy, conservative methods are most desirable. Case reports: Three patients diagnosed with CNCH were treated with 0.4% topical nitroglycerin ointment, twice daily. These included two women and one man, aged 66, 86, and 60-years-old, respectively. Two painful nodules were located on the antihelix, and one on the helix. One patient had been previously treated with intralesional corticosteroids, and another with intralesional corticosteroids, CO2 laser and photodynamic therapy. All three patients experienced significant clinical and symptomatic improvement with topical nitroglycerin. No side effects were reported. Discussion: The etiology of CNCH is uncertain. Dermal and chondral ischemia arising from perichondrial arterial narrowing has been recently described as a possible cause for this benign condition, hence the potential of nitroglycerin as a smooth muscle relaxant and vasodilator. A previous report described significant improvement in twelve patients treated with 2% topical nitroglycerin. Conclusion: Topical nitroglycerin ointment appears to be a noninvasive alternative for the treatment of CNCH. A lower concentration (0.4%) may be as effective and with fewer side effects, but more studies are warranted.
- Custo-Efectividade do Ertapenem versus Piperacilina/Tazobactam no Tratamento de Infecções do Pé Diabético em PortugalPublication . Naik, S; Pereira, R; Cabete, J; Moniz, L; Neves, J; Jansen, JPObjectivo:Avaliar o custo-efectividade do ertapenem em comparação com a piperacilina/tazobactam no tratamento das infecções, moderadas a graves, no pé diabético em Portugal. Métodos:Foi efectuada uma análise de custo-efectividade utilizando um modelo de árvore de decisão que tem em conta o desenvolvimento de resistência antibiótica ao longo do tempo com a utilização crescente em vários doentes de um mesmo antibiótico. Esta análise baseou-se num estudo semelhante previamente publicado, realizado no Reino Unido. Foram avaliados custos directos, anos de vida ajustados pela qualidade (QALY) e custos por QALY ganho. As taxas de erradicação microbiológica e de sucesso clínico foram adaptadas do estudo internacional SIDESTEP (Lipsky et al., 2005). Os custos directos associados ao tratamento das infecções do pé diabético são específicos de Portugal. O nível de incerteza dos dados foi determinado através de análises de sensibilidade probabilística. Resultados:Com base na eficiência inicial do ertapenem e da piperacilina/tazobactam reportadas no estudo SIDESTEP, o modelo utilizado sugeriu uma redução de custos de -228 euros (intervalo de confiança de 95% -1,818;916), e um ganho de QALY de 0,10 (intervalo de confiança de 95% -0,04; 0,28) quando as infecções do pé diabético são tratadas com ertapenem em detrimento da piperacilina/tazobactam. É expectável que o perfil de resistência antimicrobiana à piperacilina/tazobactam aumente a uma taxa superior ao do ertapenem após um período de utilização de 3 anos. Consequentemente, a utilização do ertapenem deverá resultar numa redução de custos -4,107 euros; intervalo de confiança de 95% -5,744; -2,930) e num ganho de QALY (0,97; 0,34; 1,71). Quando a taxa de resistência inicial ao ertapenem é superior à prevista com base no estudo SIDESTEP (0,2%), a redução de custos e os ganhos em QALY são menores. Conclusão:Tendo em conta os dados utilizados, o ertapenem pode constituir uma terapêutica mais custo-efectiva, quando comparada com a piperacilina/tazobactam no tratamento da infecção moderada a grave do pé diabético em Portugal. Contudo, reconhecem-se as limitações do presente estudo, que incluem a escassez ou ausência de dados nacionais fiáveis relativos à resistência aos antimicrobianos e à utilização de recursos.
- Cutaneous Leiomyomatosis in a Mother and DaughterPublication . Lencastre, A; Cabete, J; Gonçalves, R; João, A; Fidalgo, AA 34-year-old woman with no known medical history was evaluated for multiple painful brown nodules and papules on the anterior aspect of the trunk. She mentioned a history of similar cutaneous findings on her mother. Biopsies of three lesions revealed piloleiomyomata. Renal and adrenal ultrasound revealed an isolated simple cortical cyst, and pelvic and endovaginal ultrasound revealed two uterine myomata. The clinical diagnosis of hereditary leiomyomatosis and renal cell cancer was corroborated by the identification of a heterozygous variant on exon 5 of the fumarate hydratase gene (c.578C>T p.T193I). Identification of the tumor piloleiomyoma should alert the dermatologist to this rare genodermatosis, which is associated with an increased risk of renal cell tumors, demanding multidisciplinary follow-up, and personal and family counseling.
