- Abcesso Cerebral num Doente com Rendu-Osler-WeberPublication . Segura, U; Neves, Z; Valente, A; Pacheco, MH; Malhado, JAA telangiectasia hemorrágica hereditária é uma doença familiar rara, descrita pela primeira vez no final do século 19, caracterizada por telangiectasias mucocutâneas e viscerais, e por malformações arteriovenosas. Manifestações neurológicas ocorrem em 8 a 12% dos doentes e resultam em mais de metade dos casos de malformações arteriovenosas pulmonares. A telangiectasia hemorrágica hereditária é uma das causas mais frequentes de abcessos cerebrais recorrentes, múltiplos e bilaterais, tendendo estes a ocorrerem na 3a para a 5a década. Apresentamos o caso de uma mulher de 88 anos admitida por prostração, febre e insuficiência respiratória, com a suspeita de metastização pulmonar de neoplasia oculta, cuja investigação revelou, entretanto, um abcesso cerebral secundário a malformações arteriovenosas pulmonares. Apesar da antibioterapia e da drenagem cirúrgica do abcesso, a paciente veio a falecer. O prognóstico após drenagem dos abcessos sem ressecção das lesões pulmonares é desfavorável, podendo sua elevada mortalidade refletir um atraso diagnóstico pela falta de reconhecimento dessa associação.
- Panniculitis - a Rare Manifestation of Acute PancreatitisPublication . Neves, Z; Segura, U; Valente, A; Pacheco, MH; Malhado, JAPancreatic panniculitis is a rare skin disorder that occurs in 2---3% of pancreatic diseases, mostly associated with acute or chronic pancreatitis. Its pathophysiology is still unclear, but the release of pancreatic enzymes in circulation can be responsible for this disorder. The typical histological features are adipocyte necrosis with neutrophils infiltrate and typical ‘‘ghost cells’’. Its treatment, clinical course and prognosis are usually related with the pancreatic disease. We present a case of a 39-year-old man who presented with fever, abdominal pain, nausea and vomiting after a copious alcohol ingestion. Acute alcohol-induced pancreatitis was diagnosed. 9 days after admission he developed tender erythematous subcutaneous nodules, whose biopsy was consistent with pancreatic panniculitis. There was clinical and laboratory improvement with supportive treatment as well as skin nodules regression. Although pancreatic panniculitis is a rare condition, physicians must be aware of it to avoid delay in the diagnosis.
- Relapsing Klebsiella Pneumoniae Liver Abscesses in a Non-Asian Diabetic ManPublication . Neves, Z; Segura, U; Valente, A; Pacheco, MH; Malhado, JAThe Klebsiella pneumoniae invasive syndrome, first described in Asia, is being reported in other parts of the world. It causes liver abcsesses, with or without extrahepatic lesions. Diabetes mellitus is the most common hosts’ underlying condition. It’s frequent among asian people, even outside Asia, appearing to exist genetic factors, not yet established, increasing the risk. We present a case of a 55-year-old portuguese white diabetic man, who had a previous hospital admittion due to Klebsiella penumoniae pneumonia and a two-week latter diagnosis of liver abcsess. 4 years latter he was readmitted with nausea, chills, fever and myalgias. He had elevated inflammatory markers and the CT-scan showed 2 liver abscesses. Klebsiella pneumoniae was isolated in blood and antibiotics were given with complete clinical and imaging resolution. We present this case of relapsing Klebsiella pneumonia liver abscesses in a non-asian man emphasizing the growing incidence of this condition in Europe.
