Case Reports
Dural metastasis of atypical extraventricular neurocytoma with the codeletion of chromosomes 1p/19q.
Extraventricular neurocytoma (EVN) is a rare neoplasm described in the 2007 World Health Organization classification of tumours of the nervous system. Due to the rarity of the tumour, there is limited literature available. The clinical characteristics, pathological features, biological behaviour and outcome of EVN remain unclear, and there are challenges regarding its diagnosis and management. ⋯ Atypical pathological features included vascular proliferation, the presence of mitosis and a high MIB-1 (an antibody against Ki-67) labelling index. The disease recurred 7 months after the initial complete resection and radiation treatment, presenting with dural metastasis and codeletion of chromosomes 1p/19q. The present case history and treatment course are discussed with respect to the literature.

Comparative Study
Preoperative insertion of an intra-aortic balloon pump improved the prognosis of high-risk patients undergoing off-pump coronary artery bypass grafting.
This study investigated the efficacy and safety of preoperative insertion of an intra-aortic balloon pump (IABP) in high-risk coronary atherosclerotic disease patients undergoing off-pump coronary artery bypass grafting (OPCAB). A total of 232 patients were recruited to the study, of whom 107 underwent percutaneous insertion of an IABP prior to OPCAB. The remaining 125 patients underwent OPCAB alone. ⋯ Preoperative insertion of an IABP was associated with a shorter stay in intensive care, decreased incidence of postoperative dialysis and acute heart failure, and a reduction in postoperative mortality compared with OPCAB alone. There were no between-group differences in terms of haematocrit level, number of distal anastomoses, volume of postoperative drainage or incidence of reoperation for bleeding and postoperative stroke/cerebrovascular accident. In conclusion, preoperative insertion of an IABP improved the prognosis of high-risk CAD patients undergoing OPCAB.

This observational study investigated which of the three most common definitions of intraoperative hypotension (IOH), reported in a published systematic literature review, were associated best with anaesthetists' administration of antihypo tensive medication (AHM). IOH and AHM use in anaesthetic procedures in a mixed surgical population (n = 2350) were also reviewed. The definitions were: arterial systolic blood pressure (SBP) < 100 mmHg or a fall in SBP of > 30% of the preoperative SBP baseline; arterial SBP < 80 mmHg; a fall in SBP of > 20% of the preoperative SBP. ⋯ The three original definitions correlated poorly with the anaesthetist's judgement about applying AHM. Anaesthetists make complex decisions regarding the relevance of IOH, considering various perioperative factors in addition to SBP. Age, physical status and duration and type of surgery showed better correlations with postoperative in-patient stay than IOH.

Little is known about the impact of early invasive treatment in patients following out-of-hospital cardiac arrest (OHCA). The present study investigated the clinical characteristics and long-term prognosis of 1254 patients with suspected acute coronary syndrome, including 65 with OHCA who underwent successful cardiopulmonary resuscitation (CPR) and 1189 patients who did not require CRP. All patients underwent immediate coronary angiography even if clear signs of myocardial infarction (MI) were absent. ⋯ Cardiac biomarkers were significantly higher in CPR patients despite a shorter period from symptom onset to admission. The 6-month mortality rate was 29% in the CPR group and 4% in the non-CPR group, with > 90% of fatalities occurring ≤ 3 weeks after admission. In summary, early invasive treatment leads to a considerably reduced mortality and improved prognosis in patients after OHCA.

The findings of an expert panel convened to review critically how best to apply evidence-based guidelines for the treatment of acute pain in the Middle East region are presented. The panel recommended a three-step treatment protocol. Patients with mild-to-moderate levels of acute pain should be treated with paracetamol (step 1). ⋯ Patients reporting severe pain should be referred to a pain clinic or specialist for opioid analgesic treatment. Measures of pain and functioning that have been validated in Arabic, with culturally appropriate and easy to understand descriptors, should be used. Early and aggressive acute pain management is important to reduce the risk of pain becoming chronic, especially in the presence of neuropathic features.
