- Algoneurodistrofia Uma Entidade a ReconhecerPublication . Castanhinha, S.; Mendonça, V.; Vieira, C.; Miguel, C.; Vieira, M.; Carvalho, S.RESUMO A algoneurodistrofia é uma doença rara e subdiagnosticada, cujo diagnóstico é clínico e assenta nos sintomas típicos de dor neuropática, pseudoparalisia, tumefacção e sinais vasomotores e autonómicos num membro na ausência de lesão nervosa identificável. Em idade pediátrica apresenta geralmente um prognóstico favorável, sendo essencial o diagnóstico e a intervenção terapêutica multidisciplinar precoces para evitar sequelas ou evolução para a cronicidade. Os autores descrevem o caso de uma adolescente de 11 anos com algoneurodistrofia com evolução clínica favorável após diagnóstico e tratamento precoces. Pretendem com este caso alertar para a importância da sua identificação precoce, fazendo uma breve revisão desta entidade nosológica.

- Brachioradial pruritus in a patient with cervical disc herniation and Parsonage-Turner syndromePublication . Carvalho, S.; Sanches, M.; Alves, R.; Selores, M.Brachioradial pruritus is a chronic sensory neuropathy of unknown etiology which affects the skin of the shoulders, arms and forearms on the insertion of the brachioradialis muscle. We describe the case of a 60-year old woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900 mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries.
- Caso dermatológico: Doença de Fox-FordycePublication . Carvalho, S.; Vilaça, S.; Selores, M.The Fox-Fordyce disease represents an infrequent chronic pruritic skin rash of unknown etiology caused by obstruction of apocrine glands. Clinically it is characterized by multiple skin color and / or erythematous perifollicular papules in areas rich of apocrine glands (armpits, genital area, areolas and infra-mammary fold). Retinoids, antibiotics and topical immunomodulators have been used with varying results. We describe a case of a 16-year-old girl with Fox-Fordyce disease.
- Caso dermatológico: EscabiosePublication . Matos, C.; Machado, S.; Carvalho, S.; Dinis, M.J.; Selores, M.The authors describe a clinical case of a 5-months-old boy with widespread rash since the first month of life. Diffuse papular rash with intensive itching. The shaved skin was inconclusive so we performed biopsy to confirm the diagnosis of scabies. It’s a dermatosis very contagious caused by the mite Sarcoptes scabiei var. hominis. In infants skin eruption may have a polymorphic presentation with characteristic distribution.
- Caso dermatológico: líquen aureus segmentarPublication . Fernandes, I.; Carvalho, S.; Machado, S.; Alves, R.; Selores, M.ABSTRACT The authors describe a clinical case of a six-year-old boy with history of a segmental brownish maculopapular skin eruption on his left thoracic and lumbar wall, since the last four months.

- Caso dermatológico: Talon noir de localização atípicaPublication . Carvalho, S.; Machado, S.; Rios, M.; Selores, M.The talon noir is a post-traumatic purpuric dermatosis of acral localization, histologically characterized by the presence of blood within the stratum corneum. It is often observed in young athletes as macules of black-brown coloration on both heels. In cases of diagnostic uncertainty, curettage and dermoscopy are useful tools. No treatment is necessary because the lesions tend to resolve spontaneously. We describe the case of a five-year--old boy with an atypical talon noir
- Childhood Non-Langerhans Cell Histiocytosis – An Atypical CasePublication . Carvalho, S.; Machado, S.; Alves, R.; Vasconcelos, G.; Selores, M.Introduction: Histiocytoses correspond to a heterogeneous group of disorders characterized by the proliferation andinfiltration of histiocytes in tissues. For years, many of the histiocytoses where known by numerous names, reflecting the lack of understanding regarding their origin. Case report: A previously healthy, 4-month-old infant presented a cutaneous lesion of progressive growth on his nose since 1 month ago. The mother has a diagnosis of Sjögren syndrome. On examination, there was a firm well-defined erythematous plaque with 30 mm of diameter and raised edges, on the bridge of the nose. At the left cheek, left thoracic region and right arm there were also small erythematous papules with 5 days of evolution. The analytical study showed elevated antinuclear antibodies and anti-SS-A. Histopathological examination confirmed the diagnosis of non-Langerhans cells histiocytosis. Progressively, more annular erythematous papules and plaques appeared scattered over the face, trunk and limbs with spontaneous resolution of the first lesion on the nose. About 2 months after the initial evaluation, all lesions had regressed spontaneously, with normalization of analytical study at one year-old. Conclusion: Many authors believe that the different subtypes of histiocytosis represent only different stages of the same disease. Immunophenotyping of histiocytosis does not always identify the subtype involved, making the occurrence of atypical cases frequent.
- Chronic granulomatous disease as a risk factor for cutaneous lupus in childhoodPublication . Carvalho, S.; Machado, S.; Sampaio, R.; Guedes, M.; Vasconcelos, J.; Semedo, D.; Selores, M.Chronic granulomatous disease (CGD) is a primaryimmunodeficiency disorder that affects the phagocyticcells of the innate immune system. It is characterizedby recurrent or persistent infections with granulomaformation. Lupus-like lesions have been reported incarriers of CGD and less frequently, in patients withCGD. Immunological study in these patients areusually negative. We describe the case of an 8-yearoldboy with CGD who developed chronic and acutecutaneous lupus erythematous with angular cheilitis,oral ulcers, Raynaud phenomenon, and positiveserologies for antinuclear, anticentromere, and anti-Saccharomyces cerevisiae antibodies.
- Dissecção da artéria vertebral em adolescente orientação diagnóstica e terapêuticaPublication . Carvalho, S.; Lopes, G.; Rios, J.; Pereira, C.; Figueiroa, S.; Temudo, T.O AVC em idade pediátrica é uma situação pouco frequente, representando a dissecção arterial uma pequena percentagem da sua etiologia. Os autores apresentam o caso de um adolescente com AVC isquémico provocado por dissecção da artéria vertebral. A sintomatologia incluiu cefaleias acompanhadas de náuseas e vómitos, tonturas, alteração do estado de consciência, discurso lentificado e flexão cervical intermitente. Após o diagnóstico iniciou terapêutica anticoagulante com melhoria da sintomatologia, mas manteve dificuldade em despertar e dificuldade de evocação. São discutidas a investigação e o tratamento nesta patologia. ABSTRACT Cerebrovascular disease in paediatric age is infrequent and arterial dissection is responsible for a small percentage of its aetiology. The authors present an adolescent with a cerebrovascular ischemic event caused by vertebral artery dissection. The symptoms included headache with nausea and vomiting, dizziness, conscience impairment, slowed speech and intermittent cervical flexion. After the diagnosis, he began anticoagulant therapy with symptom improvement, but maintenance of difficulty in arousal and in evocation. Investigation and treatment in this pathology are discussed.
