Nasal allergen challenge (NAC): Practical aspects and applications from an EU/US perspective-a Work Group Report of the AAAAI Rhinitis, Rhinosinusitis and Ocular Allergy Committee.

Nasal allergen challenge (NAC) is applied in a variety of settings (research centers, specialty clinics, and hospitals) as a useful diagnostic and research tool. NAC is indicated for diagnosis of seasonal and perennial allergic rhinitis, local allergic rhinitis, and occupational rhinitis; to design the composition of allergen immunotherapy in patients who are polysensitized; and to investigate the physio-pathological mechanisms of nasal diseases. NAC is currently a safe and reproducible technique, although it is time- and resource-consuming.

Maternal temperature variation during parturition.

Objective: To characterize temperatures for normal full-term parturients.

Methods: A retrospective chart review of 189 consecutive singleton deliveries during 1996 was conducted. All available maternal sublingual temperatures were collected from the time of admission to the time of discharge from the delivery area.
