Nasal spray adherence after sinus surgery: problems and predictors.

Objectives: To assess patient adherence to nasal spray regimens after endoscopic sinus surgery (ESS) and to study factors that predict adherence.

Methods: A three-arm, randomized, blinded, controlled trial was conducted at a tertiary care academic hospital, studied via a prospective longitudinal survey, of 60 consecutive chronic rhinosinusitis patients managed with ESS and started on one of three postoperative nasal spray regimens. Structured telephone interviews were conducted after surgery over a 12-month period using a validated questionnaire that assessed both spray adherence and barriers to adherence.

Peripheral vascular disease: who gets it and why? A histomorphological analysis of 261 arterial segments from 58 cases.

Aims: This retrospective study aimed to document and illustrate the histomorphological changes underlying peripheral vascular disease (PVD). More specifically, it aimed to analyse and quantify those changes that lead to lower limb amputations. Histological changes were assessed in relation to various clinical pathologies, and significant correlations were sought thereafter.
