@heena The usual cause is a directed force sufficient to overcome the bond between the affected tooth and the periodontal ligament within the cradling alveolar socket. Avulsion results in hypoxia and eventual necrosis of the pulp. The primary goal of rapid reimplantation is to preserve the periodontal ligament, not the tooth. The avulsed tooth inevitably requires a root canal; however, if the periodontal ligament survives, the degree and timeliness of root resorption is improved and ankylosis is decreased.

@diptangshu In the current context of the COVID-19 pandemic, it is worth pointing out that even though the Centers for Disease Control and Prevention (CDC) still does not include individuals with psoriasis or other autoimmune diseases among those at high risk for COVID-19, many psoriasis patients present with associated comorbidities, such as obesity and diabetes, which put them at greater risk of getting severely ill, or dying, from COVID-19.

Virtual reality–based cognitive-behavioral therapy (VR-CBT) can reduce paranoia and anxiety in patients with psychotic disorders, results of a multicenter randomized controlled trial show. CBT is the most effective psychological treatment for people with psychosis, but its ability to reduce paranoia and improve social functioning has been limited. Geraets, with lead investigator Roos Pot-Kolder, MSc, VU University, the Netherlands, and colleagues investigated the effects of VR-CBT on paranoid thoughts and social participation in 116 outpatients who in the past month had received a diagnosis of psychotic disorder and paranoid ideation on the basis of criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Half of patients received 16 VR-CBT sessions delivered by CBT-trained therapists during an 8- to 12-week period in addition to usual treatment. The other half received only usual treatment (control patients).

@kinjal The relationship between environment, beverage temperature and performance has almost exclusively been examined from the perspective of whether cold drinks can enhance performance in hot conditions (the general consensus seems to be that they do help a very small amount compared to room temperature fluids), not the other way around. This is unsurprising as there has been far more attention given to how to improve exercise capacity in the heat. That’s despite the cold arguably being more challenging in many respects. So, if the peer-reviewed science is a bit thin on the ground, it comes down to drawing a bit more heavily on experience and common sense. Whilst my own experience of training and competing in cold conditions are not exactly comparable with elite winter sports athletes, I’ve done longish periods of cross-country skiing (as part of my winter cross-training for triathlon), competed in winter ultra endurance events like the Devizes to Westminster kayak race (where you can be racing through the night in sub-zero conditions) and I often open water swim, kayak or surf in reasonably chilly water. Also, as I’m British, I’m used to the day-to-day challenge of putting in long running and cycling miles in the middle of a typically cold U.K. winter! Based on all of those experiences and from talking to many elite athletes who do train and compete in alpine and winter sports, my strong instinct is to say that I think there are some advantages to be gained from using hot drinks over cold ones, at least when the temperature gauge drops really low.

Hello, I am suffering from tongue ulcer. How to treat tongue ulcer? It is irritating me a lot. What should I do? Do I need to seek doctor's advice? Please help.

@pipi If you have a virus, antibiotics won't help, and your body will fight the infection on its own. In the meantime, you can try some home remedies:
Get lots of rest
Drink warm or very cold fluids to help with throat pain
Eat smooth foods, such as flavored gelatins, ice cream, and applesauce
Use a cool-mist vaporizer or humidifier in your room
Gargle with warm salt water
Suck on lozenges with benzocaine or other medications to numb your throat
Take over-the-counter pain relievers such as acetaminophen or ibuprofen

@prem Erythema nodosum and pyoderma gangrenosum are the inflammatory cutaneous disorders most commonly associated with IBD. These two skin manifestations occur in 3% -12% of patients with IBD. Erythema nodosum is initially managed by identifying and treating any underlying condition, along with the skin lesions. Treatments for erythema nodosum include anti-inflammatory drugs, and cortisone by mouth or injection. Colchicine is sometime used effectively to reduce inflammation. Treatment must be customized for the particular patient and their symptoms. It is important to note that erythema nodosum, while annoying and often painful, does not threaten internal organs and the long-term outlook is generally very good.
