Response of Fibroblastic Rheumatism to Infliximab

Onset is usually sudden with symmetrical articular involvement of both small and large joints, occurrence of solid skin nodules, and rapid progression. Treatment is generally unrewarding. Here we report a severe and disabling case of FR responding favorably to infliximab therapy. After 32 weeks of continuous treatment, skin lesions dramatically improved and arthropathy partially regressed

Oral lichen planus

O líquen plano da mucosa oral (LPO) é afecção relativamente comum, que pode aparecer isolado ou associado ao líquen plano cutâneo, havendo, no entanto, significantes diferenças clínicoevolutivas: o LPO tende a ser crônico, recidivante e de difícil tratamento, levando a importante morbidade, principalmente em sua forma erosiva. Novas formas clínicas agressivas têm sido salientadas na literatura, como a forma gingivo-vulvar. Este artigo revisa a etiopatogenia, as formas clínicas, a diagnose diferencial e laboratorial, a prognose e o tratamento do LPO, além de mencionar, brevemente, a experiência dos autores com esta enfermidade, vivida no Ambulatório de Estomatologia da Divisão de Dermatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São PauloOral lichen planus (OLP) is a relatively common mucosal disease that can present isolated or associated with cutaneous lichen planus. Contrarily to its cutaneous counterpart, though, OLP tends to be chronic, relapsing, and difficult to treat. Severe morbidity is related to erosive forms, and more aggressive presentations have been described, such as the "gingivo-vulvar syndrome". This article reviews the current knowledge about the pathogenesis, clinical picture, differential and laboratorial diagnosis, prognosis, and treatment of OL

A Rare Case of Concomitant Maxilla and Mandible Brown Tumours, Papillary Thyroid Carcinoma, Parathyroid Adenoma, and Osteitis Fibrosa Cystica

Objective. The brown tumour of hyperparathyroidism is a result of a metabolic disorder caused by primary hyperparathyroidism. Report. We described a case of a 37-year-old female patient presenting bimaxillary intraoral lesions and swelling in the neck. Incisional biopsy of the oral lesion was performed and histopathological examination revealed a central giant cell lesion composed by intense haemorrhagic exudate, abundant presence of giant cells, and areas with hemosiderin pigment. The patient also presented high levels of serum calcium and parathyroid hormone, hyperfunctioning parathyroid tissue, bilateral parenchymal nephropathy, and densitometry lower than expected, showing an advanced stage of osteitis fibrosa cystica. Synchronous parathyroid adenoma and papillary thyroid carcinoma were confirmed by imaging exams and histopathologically. Conclusion. The composition of all the clinical, pathological, and imaging findings led to the final diagnosis of brown tumour of hyperparathyroidism. The occurrence of parathyroid adenoma, papillary thyroid carcinoma, and brown tumours of hyperparathyroidism in their late stage (osteitis fibrosa cystica) associated with oral brown tumours involving the mandible and maxilla is extremely rare

Síndrome de Sjögren primária: aspectos relevantes para os dentistas

Objetivo: Esta revisão de literatura tem o propósito de oferecer aos cirurgiões-dentistas entendimento sobre os principais achados clínico-epidemiológicos da síndrome de Sjögren primária (SSp), bem como ressaltar os principais aspectos etiopatogênicos e histopatológicos da doença. Métodos: Buscou-se na base de dados Pubmed/Medline e ScienceDirect os descritores “síndrome de Sjögren”, “glândulas salivares”, “xerostomia”, “diagnóstico”, “glândula salivar menor”, “etiologia”, “biopsia” entre os anos de 1991 a 2017. Discussão: A SSp é uma exocrinopatia autoimune que tem como substrato, em especial, as glândulas lacrimais e salivares, culminando com os sintomas de xeroftalmia e xerostomia. Seu principal achado morfológico é a presença de agregados de leucócitos mononucleares ao redor dos ductos e ácinos. Outras manifestações sistêmicas podem estar presentes, acarretando considerável morbidade nos pacientes acometidos. Atualmente, foi publicado o mais novo conjunto de critérios diagnósticos da doença, sendo um marco histórico no diagnóstico precoce da enfermidade, fundamental para diminuir os altos números de subdiagnósticos e otimizar a conduta clínica. Conclusão: Esta revisão abordou os aspectos clínicos-epidemiológicos, histopatológicos e etiopatogênicos da SSp, objetivando melhor compreensão dessa doença multifatorial e, portanto, a necessidade de uma conduta multidisciplinar e do papel fundamental do cirurgião-dentista no manejo dos pacientes acometidos por essa síndrome.Objective: The aim of this present review is to provide dentists a better understanding of Primary Sjögren’s syndrome (SSp), clinical and epidemiological findings, also the etiopathogenic and histopathological features of the disease. Methods: The search was based on Pubmed/Medline and ScienceDirect database from 1991 to 2017. It was used keywords: “Sjögren’s syndrome”, “salivary gland”, “xerostomia”, “pathogenesis”, “diagnosis”, “minor salivary gland”, “ethiology”, “biopsy”. Discussion: Primary Sjögren’s syndrome (SSp) is an autoimmune exocrinopathy involving mainly the lacrimal and salivary glands, resulting in reduced secretory functions and classical sicca symptoms, such as dry eyes and dry mouth. The hallmark of the histopathological features is the presence of aggregates of mononuclear leukocytes surrounding ducts and acini. Others systemic manifestations can also be present, leading to considerable morbidity in the affected patients. The lastest diagnosis criteria of SSp was published in 2017, becoming a historical landmark in the early diagnosis of the disease, reducing the high number of underdiagnosis and improving therapeutic intervention. Conclusion: This review approached the clinical-epidemiological and histopathological features, and etiopathogenic factors of SSp, supporting a better comprehension of this multifactorial disease and needing a multidisciplinary approach and the role of the dentist in the clinical conduct of the patients affected by this syndrome

Carcinoid syndrome - Case report

Carcinoid tumors are rare neoplasms with, an estimated incidence of I to 2 cases per 100, 000 inhabitants. The malignant carcinoid syndrome, characterized by flushing, diarrhea, abdominal pain and, less frequently, pellagra, bronchospasm and valvular disease, occurs in less than 10% of patients. Nevertheless, in advanced stages of the disease, the incidence is about 40 to 50%. Retrospective studies and descriptive case series have shown that cutaneous involvement is relatively common but has rarely been reported. We present a case of carcinoid syndrome diagnosed with basis on skin findings on clinical examination

Oral lichen planus: case series and experience in a tertiary dermatology service in Brazil

Abstract Background: Lichen planus is an inflammatory disease that can affect both the skin and mucous membranes, including the oral mucosa. There is very little original Brazilian dermatology literature about oral lichen planus. Objective: To describe the clinical, pathological, and treatment data of 201 patients diagnosed with oral lichen planus followed at the Stomatology Outpatient Clinic of Hospital das Clínicas, Universidade de São Paulo, from 2003 to 2021. Method: The patients demographic profile, the morpho-topographic features of the lesions, the treatment employed, and the possible presence of squamous cell carcinoma were analyzed. Results: The disease was more common in women over 50 years of age, tending to be chronic, with a large number of cases showing cicatricial sequelae in the mucosa. Topical treatment with potent corticosteroids was shown to be effective in the vast majority of cases. Squamous cell carcinoma in oral lichen planus cicatricial sequelae was observed in eight cases. Study limitations: Retrospective study of medical records, with gaps regarding the filling out of data; unequal observation time among the studied cases. Conclusions: This is the largest Brazilian dermatology series on oral lichen planus. The response to topical corticoid therapy was excellent in the vast majority of cases. The high prevalence of atrophic lesions, demonstrating the chronicity and tissue destruction potential of this disease, may explain the large number of cases of squamous cell carcinoma
