Infection with 2009 H1N1 influenza virus primes for immunological memory in human nose-associated lymphoid tissue, offering cross-reactive immunity to H1N1 and avian H5N1 viruses.

Influenza is a highly contagious mucosal infection in the respiratory tract. The 2009 pandemic H1N1 (pH1N1) influenza virus infection resulted in substantial morbidity and mortality in humans. Little is known on whether immunological memory develops following pH1N1 infection and whether it provides protection against other virus subtypes.

Nontuberculous mycobacterial adenitis: effectiveness of chemotherapy following incomplete excision.

Background: Management of lymphadenopathy caused by nontuberculous mycobacteria (NTM) is primarily surgical. Where this cannot achieve sufficient clearance of infected nodes, chemotherapy is often given.

Aim: This study compared results of surgery alone with surgery followed by chemotherapy in instances where there was incomplete surgical removal of diseased tissue.

A simple and reliable predictor for an adequate laryngeal view with rigid endoscopic laryngoscopy.

Objectives: It is sometimes impossible to obtain an adequate laryngeal view during rigid endoscopic laryngoscopy. This may be due to a high tongue base. Our study seeks to determine a correlation between tongue base level and the adequacy of laryngeal view obtained with a 70-degree rigid endoscope.
