Cavernous sinus syndrome is characterized by ophthalmoplegia, diplopia, facial hypoesthesia, Horner syndrome and proptosis. The authors present a clinical case of an 89-year-old woman presented to the emergency department with complaints of vomiting, severe left frontotemporal headache, photophobia, left ptosis and diplopia with less than 24 hours of evolution. Neurological examination revealed ptosis and limitation of all eye movements in the left eye. Cranioencephalic computed tomography and magnetic resonance imaging showed an expansive lesion with expression in the suprasellar cistern and in the left cavernous sinus, suggestive of a macroadenoma with signs of hemorrhagic transformation. Cavernous sinus syndrome has several etiologies, as cerebrovascular diseases, infectious diseases, and trauma. In addition to the clinical history and physical examination, imaging tests are essential to determine the etiology behind this syndrome.

Celiac Patient With New Episodes of Diarrhea: A Case Report

Celiac disease is a relatively common autoimmune disease that affects the gut's ability to process gluten. It is frequently associated with other autoimmune diseases. In this article, the authors present a clinical case of a 65-year-old female patient with a history of celiac disease and autoimmune hypothyroidism. This patient was admitted to the emergency room with generalized edema and chronic diarrhea with mucus as well as reports of unusual weight loss. A requested fecal analysis tested positive for fecal calprotectin. An endoscopic study further displayed flattening of the intestinal villi. A subsequent biopsy expressed overlapping evidence for both celiac disease and lymphocytic colitis. This case illustrates how a diagnosis of microscopic colitis should be explored when celiac patients with a history of a stable gluten-free diet display a sudden onset of chronic diarrhea. As the symptoms associated with this disease can often become debilitating, an early diagnosis and treatment are crucial.

Lymphomas result from the proliferation of malignant lymphocytes, which can affect lymph nodes, blood, and other organs. Primary involvement of the spine by haematological diseases is rare. Non-Hodgkin's lymphoma with an extranodal location most frequently involves the gastrointestinal tract and airways, affecting the bone, muscle, and nervous system. We present a clinical case of an atypical form of non-Hodgkin's lymphoma. A 78-year-old woman was admitted to the hospital with complaints of pain in the lumbar region, hip, and left leg for the last month. Computed tomography of the lumbar spine revealed a mass of left paravertebral tissue with involvement from L3 to L5. Thoraco-abdominal CT-guided biopsy revealed diffuse large-cell non-Hodgkin B lymphoma. The remainder of the study did not show lymphatic involvement, so a diagnosis of primary extranodal large cell non-Hodgkin B lymphoma was made.

A doença de Madelung é uma condição rara, caracterizada pelo depósito maciço de gordura. Esta doença é conhecida como lipomatose simétrica múltipla ou benigna. Encontram-se descritos dois tipos de doença. No tipo 1, a gordura acumula-se no pescoço, ombros, membros superiores e tronco superior. No tipo 2, os lipomas distribuem-se por todo o corpo, incluindo nos membros inferiores. Os doentes geralmente referem algum desconforto, no entanto, em casos avançados, os lipomas podem causar sintomas como dispneia ou disfagia. Os autores apresentam o caso clínico de um doente do género masculino de 70 anos, referenciado para o Serviço de Urgência por dispneia com alguns meses de evolução, com agravamento nos últimos 6 dias, associada a tosse. Ao exame objetivo, destacava-se a presença de lipomas a nível da região cervical e torácica, com distribuição simétrica e circulação venosa colateral. Em angio-tomografia computorizada (TC) cervical e torácica, evidenciou-se a presença de proliferação da gordura cervical simétrica sugestiva de doença de Madelung, com compressão da veia jugular e braquiocefálica direita, assim como, formação de veias colaterais e consolidação peribrônquica dos lobos inferiores e médio com broncograma aéreo. Admitido no Serviço de Medicina para antibioterapia e oxigénio suplementar. Apresentou uma evolução clínica e analítica favoráveis, tendo alta ao quinto dia de hospitalização, orientado para consulta de Cirurgia. O caso apresentado corresponde a uma doença de Madelung tipo 1, em que o envolvimento mais profundo levou ao desenvolvimento de dispneia, agravado por intercorrência infeciosa. O diagnóstico desta patologia é baseado sobretudo na história clínica, exame objetivo (com a presença de múltiplos lipomas simétricos) e estudo imagiológico. A etiologia desta patologia permanece desconhecida. Atualmente, a cirurgia é o único tratamento disponível, apesar da elevada taxa de recorrência.

A amoxicilina/ácido clavulânico é um antibiótico muito usado na prática clínica para diversas infeções. Está associada a uma pequena percentagem de casos de lesão hepática secundária a fármacos, sendo a hepatite e colestase complicações raras. Os autores apresentam o caso clínico de doente, de 65 anos, género masculino, admitido no serviço de urgência por dor abdominal, colúria, acolia fecal, prurido generalizado e anorexia com 4 dias de evolução. Nos 21 dias prévios, fez curso de 7 dias de antibioterapia com amoxicilina/ácido clavulânico por amigdalite, negando uso de outros fármacos. Dos exames complementares efetuados, destaca-se hiperbilirrubinémia direta, elevação das transaminases, fosfatase alcalina e gama-GT. As serologias víricas, bacterianas e de auto-imunidade foram negativas. Realizou biópsia hepática que mostrou inflamação hepatocelular, colestase e lesão dos ductos biliares. Conclui-se tratar-se de hepatite colestática secundária a amoxicilina/ácido clavulânico. Foi submetido a terapêutica de suporte, com colestiramina e ácido ursodesoxicólico para controlo de prurido, não realizando nenhum tratamento específico.

Hyperviscosity syndrome (HVS) is a life-threatening complication. The clinical manifestations include a variety of symptoms like visual symptoms, altered mental status, stroke or congestive heart failure. Prompt treatment is needed to avoid progression to multisystem organ failure. We report a case of a 73-year-old man with a 3-months history of headaches and altered mental status. His neurological exam showed symmetrical decreased pain, thermal and tactile sensitivity in the upper and lower limbs and symmetrical decreased muscle strength in the lower limbs. His eye exam showed retinal hemorrhages and dilated retinal veins. His blood counts showed anemia, increased C-reactive protein, sedimentation rate and serum viscosity. He had an elevated immunoglobulin M and serum immunofixation revealed Ig M-kappa paraprotein. The bone marrow aspiration and biopsy revealed a Waldenström Macroglobulinemia. He was diagnosed with HVS and was treated with plasmapheresis, chemotherapy and fluids.HVS diagnosis requires a high degree of clinical suspicion, andclinicians should be aware of suggestive clinical and laboratory findings.
