The autopsyinterview is an anomaly which arose in Hong Kong at a time when the Coroner did not speak the local language and the police officer investigating the death had very little medical knowledge. The hospital anatomical pathologists and forensic pathologists were therefore delegated the task of obtaining medical information from the Cantonese speaking next-of-kin which may be related to the death and providing a written English summary for the Coroner. The legal authority on the decision to autopsy or to waive an autopsy had...

Overview of conventional molecular techniques in lymphomas

The use of molecular techniques in hematolymphoid pathology started with cloning of the immunoglobulin and T cell receptor genes. [1] This is followed by the cloning of a number of translocation breakpoints in some common lymphoma types.[2-4] Assay of chromosomal breakpoints not only helps in confirming a clonal proliferation but also prov ides an indication of the type of lymphoma. The main application is to establish clonality or lineage of a lymphoid proliferation.

Background

G6PD catalyzes the conversion of glucose-6-phosphate (G6P) to 6-phosphogluconate concurrent with reduction of NADP to NADPH, which in turn acts through glutathione and catalase pathways to detoxify hydrogen peroxide, thus counteracting oxidative stress to the cell. In the body, red cells are most susceptible to oxidative damage because oxygen radicals are generated continuously as haemoglobin cycles from deoxygenated to oxygenated forms, as well as being readily exposed to exogenous oxidizing agents present in the blood. Hence G6PD deficiency is a prototype cause of haemolytic anaemia due to intrinsic red cell enzyme...

Wilson disease (WD) (MIM # 277900) is an autosomal recessive disorder of copper transport. Clinical manifestations of WD vary widely. The age of onset ranges from three to more than 50 years of age. The initial onset of symptoms can be hepatic, neurological, psychiatric or as an acute haemolytic crisis. The prevalence of WD has been estimated to be approximately 1 in 30,000 in the Caucasian population. Although the prevalence of WD in the Hong Kong...

In the past three years, we have witnessed the revived recognition of the importance of the specialty of Clinical Microbiology and Infection. The SARS outbreak reminded the medical profession that the line of defence which we had built against infection was still not robust enough to handle major outbreaks. Three reports were published after the outbreak. They outlined the deficiencies found and recommended what should be done for the future.1-3 Many of the recommendations are relevant and will impact on the future development of the specialty of Clinical Microbiology and Infection. Let me quote from the report of the...

Avian influenza A subtype H5N1 is endemic in poultry across south-east Asia and continues to cause zoonotic disease in humans. So far, transmission of virus from avian to humans appears very inefficient and sustained transmission from human-to-human has not occurred. However, with the continued opportunity for human exposure over an ever increasing geographic range, it is possible (though not inevitable) that H5N1 virus may acquire the ability to transmit efficiently from human-to-human, leading to a pandemic.

Human disease caused by H5N1 influenza...
