Randomized Controlled Trial Clinical TrialCophenylcaine spray vs. placebo in flexible nasendoscopy: a prospective double-blind randomised controlled trial.
Practices vary across the UK on the use of topical preparation prior to flexible fibreoptic nasendoscopy. In this double-blind study, we randomised 98 patients to receive cophenylcaine or placebo nasal spray before flexible nasendoscopy. A visual analogue scale (1-100) was used to record pain, unpleasantness of taste and overall discomfort experienced. ⋯ There was no significant difference in pain or overall discomfort experienced between the two groups; however, the sensation of bad taste was significantly worse in the cophenylcaine group. In linear regression, factors that predicted the overall unpleasantness of the experience were primarily pain experienced and secondarily unpleasantness of taste. We conclude that the routine use of cophenylcaine for nasal preparation is not justified before flexible nasendoscopy.

ReviewUpdate on treatment guidelines for acute bacterial sinusitis.
Acute bacterial sinusitis (ABS) is a common complication of viral upper respiratory tract infections and represents a considerable social burden both in terms of diminished quality of life for the patient and the economic implications of decreased productivity and treatment costs. Several national health authorities have developed guidelines for the management of ABS, which aim to promote rational selection of anti-bacterial therapy to optimise clinical outcomes while minimising the potential for selection of anti-bacterial resistance as a result of inappropriate anti-bacterial usage. This article provides an overview of current guidelines, with particular focus on the clinical significance of variations in treatment recommendations and new treatment options, such as the ketolide telithromycin, which was recently added to a number of national treatment guidelines.

Pulmonary function studies in Kuwaiti children with sickle cell disease and elevated Hb F.
Conflicting ventilatory defects have been reported in children with sickle cell disease (SCD). In Kuwait, the disease is relatively mild with a low incidence of acute chest syndrome and other complications, presumably due to the Arab-Indian haplotype chromosomal background and elevated Hb F levels. There have been no previous studies of pulmonary function in patients with this haplotype. ⋯ This study revealed an early restrictive and obstructive pulmonary function pattern in steady state children with SCD. The finding also indicates that the changes of PFT parameters in SS patients could not be attributed to anaemia per se as patients with HbH who also have chronic anaemia did not show similar changes. This observation underscores the early occurrence of pulmonary involvement, even in patients with an otherwise relatively mild SCD.
