Plasmacytoid Lymphocytes: A Diagnostic Clue for Dengue Fever

Dermoscopy rainbow pattern as a diagnostic clue for early angiosarcoma

Angiosarcomas of the scalp are aggressive invasive tumors that, more often than not, mimic benign painless skin lesions. We here report a case of angiosarcoma that was timely diagnosed and treated thanks to the dermoscopic rainbow pattern.

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...

Recurrent Acute Pancreatitis: A Diagnostic Clue to Primary Hyperparathyroidism

Molecular-level dengue fever diagnostic devices made out of paper.

This paper describes the development of nucleic acid detection in paper using a combination of commercial fluorescent probes and DNA ladders, and provides us with a better understanding of the interactions between double-stranded DNA (the amplified products in this study), fiber structures in paper, and fluorescent probes. The amplified products (the reverse-transcription and amplification of d...

Dengue and dengue hemorrhagic fever.

Continued geographic expansion of dengue viruses and their mosquito vectors has seen the magnitude and frequency of epidemic dengue/dengue hemorrhagic fever (DF/DHF) increase dramatically. More than 200,000,000 infections and over 2 million cases of DHF occur annually, and dengue is one of the most important emerging tropical diseases in the world. Its dramatically increased incidence and geogr...
