The purpose of the study is to determine whether the PH94B nasal spray is effective for Acute Treatment of the symptoms of Social Anxiety Disorder (SAD) in adult men and women. The hypothesis is that PH94B nasal spray (.8 micrograms) has a rapid onset of efficacy to improve performance and interaction anxiety in patients with diagnosed Social Anxiety Disorder (SAD).

The experience of pain is common among hospital inpatients. Orthopaedic surgery often results in significant pain, which may last for some time. About one in eight people will experience long-term or chronic pain after surgery, which can impact on quality of life and mood. Some risk factors are known for chronic post surgical pain (CPSP) and these include patient factors, surgical factors and anaesthetic factors. We know that mood problems (anxiety and depression) increase the risk of CPSP. What is not known is how short term changes in mood are related to the experience of pain after surgery and how this impacts on CPSP. This study is designed to investigate the relationship between both short and long-term mood problems and short and long-term pain and quality of life after orthopaedic surgery. The study will provide valuable information to allow us to design a psychological intervention, which might reduce the risk of short-term post surgical pain and CPSP. This study also aims to measure a number of other variables, which may be related to CPSP including medication use, other medically unexplained symptoms and catastrophic thinking in response to pain. All patients having planned orthopaedic surgery will be asked to enter the trial. Those consenting to involvement will complete a questionnaire assessing the variables described above. They will be divided into two groups depending on whether they have significant pain on the day after their surgery. As the primary aim of the study, the rates of significant anxiety or depression will then be compared between these two groups. Secondary outcomes will be assessed by a questionnaire sent to the patients at 6 months after their surgery. Descriptive statistics will be produced for all the variables and use to model a future study, which would assess the effect of a psychological intervention on acute and chronic post surgical pain. Our hypothesis is that patients are more likely to experience acute anxiety and depression or display catastrophic thinking if they suffer significant post-surgical pain. The study is powered to reliably detect a three-fold difference in the prevalence of psychopathology between patients with and without acute pain on day 1 after elective orthopaedic surgery.
