In healthy subjects nasal nitric oxide does not correlate with olfactory sensitivity, trigeminal sensitivity, and nasal airflow.

Objective: The aim of the study was to determine the relationship between nasal nitric oxide (nNO) and olfactory sensitivity, trigeminal sensitivity and nasal airflow in healthy subjects.

Study Design: This is a correlational study.

Setting: This study was carried out in a tertiary referral centre.

Acupuncture is associated with a positive effect on odour discrimination in patients with postinfectious smell loss-a controlled prospective study.

Introduction: Smell disorders are common in the general population and occur e.g., after infections, trauma or idiopathically Treatment strategies for smell loss range from surgery, medication to olfactory training, depending on the pathology, but they are limited This study examined the effect of acupuncture on olfactory function.

Naphthalene: irritative and inflammatory effects on the airways.

Objective: This cross-sectional study determined whether acute sensory irritative or (sub)chronic inflammatory effects of the eyes, nose or respiratory tract are observed in employees who are exposed to naphthalene at the workplace.

Methods: Thirtynine healthy and non-smoking male employees with either moderate (n = 22) or high (n = 17) exposure to naphthalene were compared to 22 male employees from the same plants with no or only rare exposure to naphthalene. (Sub)clinical endpoint measures included nasal endoscopy, smell sensitivity, self-reported work-related complaints and the intensity of naphthalene odor and irritation.

Postoperative delirium is an independent risk factor for posttraumatic stress disorder in the elderly patient: a prospective observational study.

Background: Posttraumatic stress disorder (PTSD) may appear after hospitalisation for surgery with general anaesthesia in elderly patients. Prevalence and risk factors in this setting are unknown. Postoperative delirium could be a risk factor.

[The Post-Traumatic Stress Syndrome 14-Questions Inventory (PTSS-14) - Translation of the UK-PTSS-14 and validation of the German version].

Background: Hospitalization may represent a stressor that can lead to Posttraumatic stress disorder (PTSD).

Methods: Translation of the UK-PTSS-14, conducted in accordance with ISPOR principles and validation with the PDS (86 patients).

Results: The ROC analysis showed that the German version of PTSS-14 is a valid instrument with high sensitivity (82%) and specificity (92%) with the optimum cut-off point at 40 points.
