Is it better to treat chronic hepatitis B as early as possible?—Con

Ideally, treatment of chronic hepatitis B in its early stage prior to irreversible liver damage should be most effective in preventing adverse clinical outcome. However, currently available treatments have low efficacy in achieving sustained response among patients in the early phase of chronic hepatitis B infection when the immune response to hepatitis B virus is weak. This review will provide evidence why a ‘wait and monitor’ approach is appropriate for chronic hepatitis B patients who are in the immune tolerant phase.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73513/1/j.1440-1746.2004.03660.x.pd

The evolution of peripheral nerve treatment for trigeminal neuralgia - peripheral nerve surgery

Trigeminal neuralgia typically presents with a sudden and severe facial pain. Although peripheral nerve injection can produce good pain relief in the treatment of trigeminal neuralgia, their effect may not be permanent. Surgical treatment has always been an alternative for patients who do not respond well to medical treatment or, for those who are severely affected by the side effects of anticonvulsants. Unknown to most young healthcare providers, surgical treatment was the first line treatment at the turn of the 19th century till 1960s. This review narrates the evolution of peripheral nerve treatment for trigeminal neuralgia over the last 150 years

The evolution of peripheral nerve treatment for trigeminal neuralgia - peripheral injections

Trigeminal neuralgia presents as a characteristic severe painful condition that usually afflicts the area(s) innervated by the branches of the facial sensory nerves, especially the elderly females. The diagnosis can usually be made based solely on the presenting clinical signs and symptoms. Early literatures had revealed that there have always been two major means of treatment for trigeminal neuralgia; medical and surgical. Medical treatments involved systemic intake of various drugs or the topical applications of many different materials, not forgetting that bleeding and purging has been tried in the past. The introduction of anti-convulsants during thesecond World War had changed completely the way this painful condition was treated as this therapy later become the mainstay treatment for trigeminal neuralgia. Their beneficial effects, however may not be long lasting. This review summarises the evolution of peripheral nerve injection as a treatment for trigeminal neuralgia over the last 150 years

Asian-Pacific consensus statement on the management of chronic hepatitis B: a 2008 update

Large amounts of new data on the natural history and treatment of chronic hepatitis B virus (HBV) infection have become available since 2005. These include long-term follow-up studies in large community-based cohorts or asymptomatic subjects with chronic HBV infection, further studies on the role of HBV genotype/naturally occurring HBV mutations, treatment of drug resistance and new therapies. In addition, Pegylated interferon α2a, entecavir and telbivudine have been approved globally. To update HBV management guidelines, relevant new data were reviewed and assessed by experts from the region, and the significance of the reported findings were discussed and debated. The earlier “Asian-Pacific consensus statement on the management of chronic hepatitis B” was revised accordingly. The key terms used in the statement were also defined. The new guidelines include general management, special indications for liver biopsy in patients with persistently normal alanine aminotransferase, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy. Recommendations on the therapy of patients in special circumstances, including women in childbearing age, patients with antiviral drug resistance, concurrent viral infection, hepatic decompensation, patients receiving immune-suppressive medications or chemotherapy and patients in the setting of liver transplantation, are also included

Genomic landscape of lung adenocarcinoma in East Asians

Lung cancer is the world’s leading cause of cancer death and shows strong ancestry disparities. By sequencing and assembling a large genomic and transcriptomic dataset of lung adenocarcinoma (LUAD) in individuals of East Asian ancestry (EAS; n = 305), we found that East Asian LUADs had more stable genomes characterized by fewer mutations and fewer copy number alterations than LUADs from individuals of European ancestry. This difference is much stronger in smokers as compared to nonsmokers. Transcriptomic clustering identified a new EAS-specific LUAD subgroup with a less complex genomic profile and upregulated immune-related genes, allowing the possibility of immunotherapy-based approaches. Integrative analysis across clinical and molecular features showed the importance of molecular phenotypes in patient prognostic stratification. EAS LUADs had better prediction accuracy than those of European ancestry, potentially due to their less complex genomic architecture. This study elucidated a comprehensive genomic landscape of EAS LUADs and highlighted important ancestry differences between the two cohorts

College of Radiology, Academy of Medicine of Malaysia position on whole body screening CT scans in healthy asymptomatic individuals (2008)

To date, the College of Radiology (CoR) does not see any clear benefit in performing whole body screening computed tomography (CT) examinations in healthy asymptomatic individuals. There are radiation risk issues in CT and principles of screening should be adhered to. There may be a role for targeted cardiac screening CT that derives calcium score, especially for asymptomatic medium-risk individuals and CT colonography when used as part of a strategic programme for colorectal cancer screening in those 50 years and older. However, population based screening CT examinations may become appropriate when evidence emerges regarding a clear benefit for the patient outweighing the associated radiation risks
