    To characterize the dengue epidemic that recently occurred in Malaysia, we sequenced cDNAs from nine 1993-1994 dengue virus type-3 (DEN-3) isolates in Malaysia (DEN-3 was the most common type in Malaysia during this period). Nucleic acid sequences (720 nucleotides in length) from the nine isolates, encompassing the precursor of membrane protein (preM) and membrane (M) protein genes and part of the envelope (E) protein gene were aligned with various reference DEN-3 sequences to generate a neighbor-joining phylogenetic tree. According to the constructed tree, the nine Malaysian isolates were grouped into subtype II, which comprises Thai isolates from 1962 to 1987. Five earlier DEN-3 virus Malaysian isolates from 1974 to 1981 belonged to subtype I. The present data indicate that the recent dengue epidemic in Malaysia was due to the introduction of DEN-3 viruses previously endemic to Thailand.

    The prevalence of mycobacterial infection in AIDS patients has increased in Japan. This report describes details of the clinical and radiological features of eight AIDS patients with mycobacterial disease (6 with M. tuberculosis infection and 2 with M. kansasii infection) in our hospital during the period from October 1995 through February 1997. Six of the 8 were men, and two were women. The mean age was 36.5 years. Six were Japanese, one was from Myanmar, and one was Malaysian. The median CD4 positive T lymphocyte counts (CD4 count) at the time of diagnosis of the M. tuberculosis was 75.5 (range 14-569/microliter, and the M. kansasii was 21.5 (range 19-24)/microliter. Clinical findings and symptoms of all patients were non-specific, but almost all patients had a cough and fever. In the radiographic findings, the patients of the M. tuberculosis group presented multiple hilar and mediastinal lymphadenopathy, miliary shadow, and obstructive pneumonia. Both M. kansasii patients showed a multiple infiltration shadow. There were no drug resistant strains in M. tuberculosis except on isolate with moderate resistant. to Streptomycin. These observations suggest that AIDS-associated mycobacterial disease shows atypical clinical and radiological features in some cases, especially in advanced stages of AIDS. Therefore, we need to recognize the characteristics of the clinical and radiological features of the patients with mycobacterial diseases and AIDS.

    BACKGROUND AND AIM: In recent years, the incidence of colorectal cancer has been increasing, and it is now becoming the major cause of cancer death in Asian countries. The aim of the present study was to develop Asian expert-based consensus to standardize the preparation, detection and characterization for the diagnosis of early-stage colorectal neoplasia.

    METHODS: A professional group was formed by 36 experts of the Asian Novel Bio-Imaging and Intervention Group (ANBI2 G) members. Representatives from 12 Asia-Pacific countries participated in the meeting. The group organized three consensus meetings focusing on diagnostic endoscopy for gastrointestinal neoplasia. The Delphi method was used to develop the consensus statements.

    RESULTS: Through the three consensus meetings with debating, reviewing the literature and regional data, a consensus was reached at third meeting in 2016. The consensus was reached on a total of 10 statements. Summary of statements is as follows: (i) Adequate bowel preparation for high-quality colonoscopy; (ii) Antispasmodic agents for lesion detection; (iii) Image-enhanced endoscopy (IEE) for polyp detection; (iv) Adenoma detection rate for quality indicators; (v) Good documentation of colonoscopy findings; (vi) Complication rates; (vii) Cecal intubation rate; (viii) Cap-assisted colonoscopy (CAC) for polyp detection; (ix) Macroscopic classification using indigocarmine spray for characterization of colorectal lesions; and (x) IEE and/or magnifying endoscopy for prediction of histology.

    CONCLUSION: This consensus provides guidance for carrying out endoscopic diagnosis and characterization for early-stage colorectal neoplasia based on the evidence. This will enhance the quality of endoscopic diagnosis and improve detection of early-stage colorectal neoplasia.
