RESUMO
Prostate cancer can be complicated by spontaneous intracranial haematoma. In the acute setting, an intracranial haematoma can appear isodense on CT scanning, especially if a coagulopathy is present. Diffuse intravascular coagulation (DIC) can be the underlying pathophysiological mechanism that leads to spontaneous bleeding. It is important to recognize the possibility of DIC in cancer patients, since it has important therapeutical implications that may be life saving.

BACKGROUND: Grouping of patients based on a predominant dyspeptic symptom is frequently employed in management strategies for dyspepsia. Such subdivision, however, suggests that dyspeptic symptom patterns are constant over time. OBJECTIVE: To investigate the behavior of symptoms over time and to study the effects of diagnostic procedures and treatment on the pattern and severity of dyspeptic symptoms. METHODS: Patients with persistent dyspeptic symptoms completed a validated questionnaire at regular time intervals as part of a clinical trial in primary care. Based on predominant symptoms, patients were classified into ulcer-like dyspepsia, reflux-like dyspepsia, dysmotility-like dyspepsia, and unspecific dyspepsia according to the Rome II criteria. RESULTS: Questionnaires were returned at baseline, 1, 3, and 6 months by 185, 172, 169, and 170 patients, respectively. At baseline, 35% of patients reported predominantly reflux-like dyspepsia, 34% had ulcer-like dyspepsia, 16% had dysmotility-like dyspepsia, and in 15% symptoms were not specific. During the 6-month follow-up period, only 35% of patients kept the same predominant symptom. Symptom (in)stability was not dependent on diagnostic procedures or on therapy with proton pump inhibitors, H2-receptor antagonists, prokinetics, or antacids. CONCLUSION: In the majority of dyspeptic patients, symptoms change continuously as time goes on. Symptom instability is not influenced by diagnostic procedures or therapy. Thus, there is little sense in symptom-based management of dyspepsia in primary care.
