Use of Chest X-Ray Examination as a Diagnostic Aid for Detection of Dengue Haemorrhagic Fever

Dot enzyme immunoassay: an alternative diagnostic aid for dengue fever and dengue haemorrhagic fever.

A dot enzyme immunoassay (DEIA) for the detection of antibodies to dengue virus was tested for use as a tool in the presumptive diagnosis of dengue fever and dengue haemorrhagic fever. Paired sera from the following groups of patients were tested using the DEIA and the haemagglutination inhibition (HI) test: those with primary dengue fever; those experiencing a second dengue infection; and febr...

Patient effective dose evaluation for chest X-ray examination in three digital radiography centers

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

Dengue haemorrhagic fever

Factors increasing the risk of DHF outbreaks The occurrence of DHF outbreaks is linked to a number of factors, including the density of mosquito vectors, particularly that of Aedes aegypti. The precise population density of Ae. aegypti that is needed to sustain dengue virus transmission epidemically or endemically has yet to be determined, but experience in Singapore in recent years suggests th...

Dengue haemorrhagic fever

The two basic methods for establishing a laboratory diagnosis of dengue infection are detection of the virus (e.g. culture) or detection of anti-dengue antibodies (serology). Until recently, detection of the virus implied solely the recovery of the virus by culture; however, current procedures can detect dengue virus RNA and specific dengue virus antigens. Consequently, these procedures are lik...
