Probenecid may be used if undersecretion of uric acid is present (24-hour urine uric acid less than 800 mg). It is, however, not recommended if a person has a history of kidney stones. Pegloticase is an option for the 3% of people who are intolerant to other medications. It is a third line agent. Pegloticase is given as an intravenous infusion every two weeks, and reduces uric acid levels. Pegloticase is useful decreasing tophi but has a high rate of side effects and many people develop resistance to it. Using lesinurad 400 mg plus febuxostat is more beneficial for tophi resolution than lesinural 200 mL with febuxostat, with similar side effects. Lesinural plus allopurinol is not effective for tophi resolution. Potential side effects include kidney stones, anemia and joint pain. In 2016, it was withdrawn from the European market.Lesinurad reduces blood uric acid levels by preventing uric acid absorption in the kidneys. It was approved in the United States for use together with allopurinol, among those who were unable to reach their uric acid level targets. Side effects include kidney problems and kidney stones. Treatment
The initial aim of treatment is to settle the symptoms of an acute attack. Repeated attacks can be prevented by medications that reduce serum uric acid levels. Tentative evidence supports the application of ice for 20 to 30 minutes several times a day to decrease pain. Options for acute treatment include nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, and glucocorticoids. While glucocorticoids and NSAIDs work equally well, glucocorticoids may be safer.
A nasal septum perforation is a medical condition in which the nasal septum, the bony/cartilaginous wall dividing the nasal cavities, develops a hole or fissure. This may be brought on directly, as in the case of nasal piercings, or indirectly, as by long-term topical drug application, including intranasal ethylphenidate, methamphetamine, cocaine, crushed prescription pills, or decongestant nasal sprays, chronic epistaxis, excessive nose picking and as a complication of nasal surgery like septoplasty or rhinoplasty. Much less common causes for perforated nasal septums include rare granulomatous inflammatory conditions like granulomatosis with polyangiitis. It has been reported as a side effect of anti-angiogenesis drugs like bevacizumab. Signs and symptoms
A perforated septum can vary in size and location, and is usually found deep inside the nose. It may be asymptomatic, or cause a variety of signs and symptoms. Small perforations can cause a whistling noise when breathing. Larger perforations usually have more severe symptoms. These can be a combination of crusting, blood discharge, difficulty breathing, nasal pressure and discomfort. The closer the perforation is to the nostrils, the more likely it is to cause symptoms. Cause
Infective causes include syphilis, leprosy, and rhinoscleroma. Non-infective causes include cocaine abuse, an in situ foreign body, chronic use of topical nasal decongestants, methamphetamine, facial trauma, or may develop as a consequence of nasal surgery. Treatment
Septal perforations are managed with a multitude of options. The treatment often depends on the severity of symptoms and the size of the perforations. Generally speaking anterior septal perforations are more bothersome and symptomatic.
