Treatment of central neuropathic pain (CP) following lesions of the CNS is a great challenge to the clinician. Preclinical and clinical studies indicate that neuronal hyperexcitability in damaged areas of the central nervous system plays a major role in the development of CP. Anticonvulsants are thought to act by increasing gamma-aminobutyric acid-mediated inhibition, decreasing abnormal neuronal hyperexcitability by modulating sodium and calcium channels or by inhibiting excitatory amino acid actions. ⋯ However, few randomised controlled trials on the treatment of this condition have been published. Present suggestions for anticonvulsant treatment of CP are lamotrigine as the first choice, followed by gabapentin or carbamazepine/oxcarbazepine. These compounds are considered as effective as the antidepressant amitriptyline.

Healthcare costs are rising in all areas of medicine, especially in high technology specialities such as anaesthesia. Therefore, cost containment and reduction have become major goals in many hospitals and anaesthesia departments. ⋯ However, the results are not conclusive and anaesthesia departments continue to seek ways to reduce costs. In this review, we intend to discuss cost terminology, common areas of cost containment in anaesthesia and the relationship of anaesthesia care costs to total perioperative costs.

Human infections with Babesia species, in particular Babesia microti, are tick-borne illnesses that are being recognised with increased frequency. Coinfection with ehrlichiosis and Lyme disease is also being recognised as an important feature of these tick-borne illnesses. Despite the superficial resemblance of Babesia to malaria, these piroplasms do not respond to chloroquine or other similar drugs. ⋯ Data in animal models and case-reports in humans have suggested that an atovaquone-azithromycin combination is also effective. This was confirmed in a recent prospective, open, randomised trial of clindamycin-quinine versus azithromycin-atovaquone. This paper reviews the literature on the treatment of human babesiosis and the animal models of these human pathogens.

Histoplasmosis is a systemic fungal infection that infects millions of people living in areas where the infection is endemic. However, most people with histoplasmosis have a self-limited illness that does not require treatment with an antifungal agent. ⋯ The treatment of choice for severe histoplasmosis is amphotericin B, while itraconazole is given for mild to moderate histoplasmosis. Most patients who require initial treatment with amphotericin B respond quickly and can then be switched to itraconazole to finish the course of therapy.

ReviewBivalirudin: an anticoagulant for acute coronary syndromes and coronary interventions.
Heparin is a commonly used anticoagulant in patients with coronary artery disease but its use does not always result in low rates of ischaemic and bleeding events, so the search for new anticoagulants continues. Thrombin plays a key role in both thrombosis and haemostasis and direct thrombin inhibitors modelled on the hirudin molecule found in the saliva of the medicinal leech, Hirudo medicinalis, have recently been developed. To date, the only direct thrombin inhibitor shown to reduce both the ischaemic and the bleeding complications associated with percutaneous coronary intervention (PCI) is bivalirudin, which is approved for this indication in the US and New Zealand. ⋯ Bivalirudin has been shown to significantly reduce the risk of reinfarction in patients with acute myocardial infarction (MI) treated with streptokinase, but its use for this indication is not approved in the US. It may also prove to be beneficial in patients with acute MI treated with other fibrinolytic regimens or with primary or facilitated PCI. Bivalirudin is suitable for use as an alternative to heparin in the majority of patients undergoing PCI and in patients receiving streptokinase for acute MI.
