Acute ischaemic stroke (AIS) is the leading cause of death and disability in developed nations. In the past decade pharmacologic and endovascular therapy has been approved for use in treatment of patients presenting with AIS. The time window from symptom onset to be eligible for treatment is narrow, allowing for only a small proportion of these patients to be treated. ⋯ Several studies have shown a high rate of vessel recanalisation with endovascular techniques; however, their efficacy and translation to improved patient outcome is not yet established. Advanced imaging techniques may help select patients who would predictably benefit from endovascular intervention. In the light of existing controversies, this review discusses the current evidence for intravenous and intra-arterial thrombolytics, intra-arterial mechanical thrombectomy devices, and intracranial stent placement for treatment of AIS.

Acute respiratory distress syndrome (ARDS) is a life threatening respiratory failure due to lung injury from a variety of precipitants. Pathologically ARDS is characterised by diffuse alveolar damage, alveolar capillary leakage, and protein rich pulmonary oedema leading to the clinical manifestation of poor lung compliance, severe hypoxaemia, and bilateral infiltrates on chest radiograph. Several aetiological factors associated with the development of ARDS are identified with sepsis, pneumonia, and trauma with multiple transfusions accounting for most cases. ⋯ Despite these negative studies, mortality seems to be in decline due to advances in overall patient care. Future directions of research are likely to concentrate on identifying potential biomarkers or genetic markers to facilitate diagnosis, with phenotyping of patients to predict outcome and treatment response. Pharmacotherapies remain experimental and recent advances in the modulation of inflammation and novel cellular based therapies, such as mesenchymal stem cells, may reduce lung injury and facilitate repair.

Tremor is, by definition, a rhythmic oscillation of a body part. It is the most prevalent movement disorder in clinical medicine, so doctors working in many specialities and in general practice can expect to encounter it. Most tremors can be classified on the basis of four observable clinical characteristics: anatomical pattern; the relative prominence of the tremor at rest, on maintaining a posture, and with action; tremor frequency; and tremor amplitude. ⋯ Wilson's disease and fragile X-associated tremor/ataxia syndrome are rarer conditions that may present with tremor and are very important to identify. There is a small but genuine diagnostic grey zone between Parkinson's disease and more benign tremor disorders such as essential tremor and dystonic tremor, in which resting and postural tremor coexist with mild or equivocal non-tremor parkinsonian signs. The authors review clinical features and investigational techniques that may help to discriminate this group of hard-to-classify tremors.

Stratifying preoperative risk and guiding perioperative therapy objectively has acquired critical importance, given robust data demonstrating that morbidity following non-cardiac surgery confers substantially increased risk of death, even beyond hospital discharge. The development of useful perioperative biomarkers depends fundamentally on both prospective morbidity data that enable the identification of higher risk patients as well as the translational understanding of pathophysiological mechanisms underlying postoperative organ dysfunction, the development of which may be specific to the perioperative environment. ⋯ Nevertheless, common tests/biomarkers that are widely available do provide valuable, objective information that is perhaps under-utilised perioperatively. Despite significant challenges, perioperative medicine presents exciting-arguably unique-opportunities for novel biomarker development.

This study was conducted to assess interns' level of exposure to different aspects of professional attitude and behaviour among faculty and residents. ⋯ Medical faculty and residents should be more aware of their behaviour and attitudes in practice, especially their interaction with colleagues so that students' professional behaviour can be improved.
