4 Clinical Trials for Various Conditions
The perianal region is the region around the anus. Administering a pain medication before a surgery starts is called preemptive analgesia. In some studies, this technique has been shown to be an effective way to reduce the pain that a patient experiences in the post-operative timeframe to a greater extent than would be expected simply from the pain medications alone. One theory of why this occurs suggests that the preemptive analgesia desensitizes brain and nerves to pain, thereby decreasing the response to painful stimuli, like surgery when they occur. This leads to a decrease in the amount of narcotic pain medication required after the procedure, which leads to less side effects and a quicker return to normal functioning. As perianal surgeries do not usually include a long stay in the hospital, controlling post-procedure pain is a priority. The use of preemptive analgesia is in other types of surgeries, such as orthopedics, is well established, but as the perianal region has not been well studied, its use is not the standard of care. This type of analgesia uses a combination of medications that are already in use for post-operative and non-operative pain control and administers them orally prior to the patient undergoing general anesthesia. The side effects of the medications are the same as if they had been given after surgery or for non-surgical pain. The concept of preemptive analgesia is established in other types of surgeries and it has solid basic science to support its use. The purpose of this randomized, double-blind, placebo controlled study is to determine if patients undergoing perianal surgeries could benefit from preemptive pain control. The primary outcome will be whether patients experience less post-operative pain. Patient post-operative consumption and latency until use of narcotic pain medication will be the secondary outcomes. The investigators believe that the patients receiving pain medications before their operation will require less pain medication after surgery, with minimal increased risk to the patient.
The primary objective of this pilot study is to evaluate the effect of the HPV vaccine Gardasil on anal condylomata recurrence and persistence rates in HIV positive patients.
This study is designed to identify barriers that prevent men who have sex with men from receiving doctor-recommended annual follow-up screenings for anal cancer. Men who are at the highest risk for developing anal cancer will be asked to complete a brief questionnaire (either via telephone or in writing). The questionnaire is designed to identify potential barriers to care-seeking behavior including, relationship status, financial constraints, highest level of education and knowledge about anal cancer and its precursors. The men who agree to participate in the study will then be organized into groups based on their history of coming in for follow-up screening visits after learning that they are at higher risk for developing anal cancer. These groups include 1) men that have come in for regular screening visits (at least once per year), 2) men who came in once and were then lost to follow-up, 3) men who came in for more than one screening visit and were then lost to follow-up, and 4) men who were previously lost to follow-up and then began coming in for screening again. By comparing the men's responses across the different groups, we hope to uncover key barriers and drivers to follow-up screenings for anal cancer. The goal of this study is to evaluate the differences in questionnaire responses across cohorts that may impact care-seeking behavior. We hypothesize that: * Patients who regularly comply with annual follow-up screening visits score higher on questions assessing knowledge of HPV and anal cancer. * Men in stable relationships are more likely to comply with annual screening visit recommendations. * Men who are educated by their primary care physicians about the importance of anal cancer screenings have higher screening rates.
The purpose of this study is to investigate the clinical efficacy, safety and tolerability of a Polyphenon E Ointment 10% and a Polyphenon E Ointment 15% in the treatment of external genitial warts in male and female patients.
