Conventional parenteral injection of vaccines is limited in its ability to induce locally-produced immune responses in the respiratory tract, and has logistical disadvantages in widespread vaccine administration. Recent studies suggest that intranasal delivery or vaccination in the respiratory tract with recombinant viral vectors can enhance immunogenicity and protection against respiratory dis...

OBJECTIVE To investigate the relationship between vitamin A deficiency (VAD), vitamin E deficiency (VED) and infectious diseases. PATIENTS AND METHODS We chose 684 cases of healthy children age 5 months-12 years from our hospital, measured their VA, VE from vein under the light proof condition with high-pressure liquid chromatography. Thereafter, the children who get the acute respiratory tra...

The human respiratory tract of individuals with normal lung function maintains a fine-tuned balance, being asymptomatically colonised by the normal microbiota in the upper airways and sterile in the lower tract. This equilibrium may be disrupted by the exposure to insults such as cigarette smoke. In the respiratory tract, the complex and noxious nature of inhaled cigarette smoke alters host-mic...

The aim of the article is to discuss issues associated with the occurrence of febrile illnesses in leisure and business travellers, with a particular emphasis on fevers of unknown origin (FUO).

FUO are manifestations of variou...

Lower respiratory tract infections including pneumonia were the most common diseases diagnosed in HIV/AIDS patients. Bacteria, fungi, and viruses pathogens that often detected cases required different management. Infection biomarkers procalcitonin will give clinicians scientific reasoning to determine etiology of pneumonia. However, level bacterial non-bacterial patients is still poorly underst...
