Schizophrenia is an aetiologically heterogeneous syndrome that usually becomes overtly manifest in adolescence and early adulthood, but in many cases subtle impairments in neurointegrative function are present from birth; hence it is considered to be a disorder with a neurodevelopmental component. The strongest risk factor that has been identified is familial risk with genetic loading. Other risk factors include pregnancy and delivery complications, infections during pregnancy, disturbances of early neuromotor and cognitive development and heavy cannabis use in adolescence. ⋯ However, some authors have claimed that in future it might be possible to reduce the risk for developing schizophrenia through general health policy. In clinical settings, it is helpful to map out possible early risk factors, at least familial risk for psychosis, especially in child, adolescent and young adult mental patients. Furthermore, in the future we may have predictive models combining data from genetic factors for schizophrenia, antenatal risk factors, childhood and adolescent development and clinical symptomatology, as well as brain structural and functional abnormalities.

Influenza is an infectious respiratory pathogen causing annual outbreaks and infrequent pandemics, resulting in significant morbidity, mortality and burdens on the delivery of health care. The geographical spread of highly pathogenic avian influenza (HPAI) H5N1 among poultry and wild bird populations is unprecedented. ⋯ Antiviral agents can be used to treat influenza infection and can be taken as chemoprophylaxis during influenza outbreaks. Oseltamivir has been stockpiled as part of influenza pandemic preparedness planning; however, the emergence of drug resistance may limit its clinical use.

All cases of falciparum malaria are potentially severe and life threatening, especially when managed inappropriately. A major reason for progression from mild through complicated to severe disease is missed or delayed diagnosis. ⋯ The most recent advance in antimalarial chemotherapy has been the use of artemisinin derivatives especially intravenous artesunate, which may well revolutionize the management of severe disease. Outside antimalarial therapy, mechanical ventilation and renal replacement have also played an important role in reducing mortality of this life-threatening condition.

ReviewLiving donor liver transplantation: present status and recent advances.
The first successful living donor liver transplantation (LDLT) was performed in a child in 1989 in Brisbane and in an adult in 1994 by the Shinshu group. Over the past few years, LDLT has increased worldwide and is now an established alternative to deceased donor liver transplantation. ⋯ Some of the technical highlights include selective vascular occlusion techniques for donor hepatectomy, hepatic arterial reconstruction under the microscope and the introduction of intraoperative ultrasound, graft volume estimation and hepatic venous reconstruction, all of which have improved the success rate of LDLT over the past few years. This review focuses on recent trends and surgical techniques for LDLT.

Primary headache disorders account for a substantial part of the morbidity seen in medical practice and so advances in their understanding and management are of general importance. The classification of headache disorders has recently been revised, and the importance of frequent migraine, chronic (transformed) migraine and some important, albeit rarer, conditions that were previously not included has been recognized. ⋯ Functional brain imaging of migraine and cluster headache has placed the pathophysiology of these disorders firmly and clearly in the brain. As our understanding of migraine and related syndromes has increased, new therapies have been developed which reduce the significant disability associated with these important neurological disorders.
