Introduction

Toxic Epidermal Necrolysis, often known as Lyell's Syndrome, is an uncommon and severe dermatological disorder. It was initially documented in 1956 by Alan Lyell, after whom it was named, and in most cases, it results from drug exposure, accounting for 1% of all hospitalizations for adverse drug reactions. TEN is distinguished clinically by global mucocutaneous necrolysis, with bullous lesions and epidermal detachment involving more than 30% of total body surface area. This condition is uncommon, with an annual incidence of 1-2 instances per million people. Its mortality rate is fairly high, ranging from 25% to 35% depending on the source. The pathophysiology of TEN is not well known, and numerous theories exist [1,2].

About the Study

A few ideas claim that cellular apoptosis pathways, particularly those of Tumour Necrosis Factor, Fas-FasL, and granzymes such granulysin, are involved. According to the research, patients should be hospitalised and treated preferentially in Burns Units in order to provide the best treatment conditions and assure the highest survival rates. As of the writing of this article, and despite the fact that various new treatment modalities, including immunomodulation, have been explored and proposed, the only treatment whose efficacy has been confirmed and is commonly utilised is the one based on general support care. However, for these novel therapies to be statistically significant, investigations on larger and more representative populations are required.

TEN is a significant research topic with a lot of room for new discoveries. The writers intend to evaluate and synthesise existing material and scientific evidence in this paper. Throughout the study, not only were convergence points across different authors acknowledged, but several fascinating research objectives in terms of pathophysiology and treatment strategy were also alluded to. There are still certain conflicts and differences that need to be resolved in order to maximise patient care and outcomes. Toxic Epidermal Necrolysis, also known as Lyell's Syndrome, is a severe dermatological condition that shares a nosological spectrum with Stevens-Johnson Syndrome and SJS overlap syndrome. These three syndromes are distinguished by a quick onset of high fever, widespread mucocutaneous necrolysis, and systemic toxicity, which occur mostly as a result of exposure to particular chemicals.

Because of their similarities and difficulty in discriminating, some writers regard SJS and TEN to be a single entity termed SJs. Out of intellectual curiosity, it was decided that instances with epidermal necrolysis involving less than 10% of TBSA would be classified as SJS, while those affecting more than 30% would be classified as TEN, thereby defining the TEN overlap syndrome. Most instances of TEN are caused by an atypical reaction to a dose-independent exposure to particular pharmacological groups, however it is crucial to emphasise that a tiny number of individuals acquire TEN due to unknown nonpharmacological processes. Over 220 medications have been related to TEN, with varying degrees of frequency. Because there is no reliable test that reliably establishes a particular

Its application distributes drugs into five different categories very probable probable possible unlikely or very unlikely ( Amongst the many pharmacological groups that have been linked to TEN, the most frequent are the following: sulphonamides, especially cotrimoxazole, that represent nearly 33% of all cases in adults; antiepileptics such as phenytoin, the most frequent in paediatric ages, carbamazepine and phenobarbital; allopurinol; oral penicillin; non-steroid anti-inflammatory drugs with long half-life, namely pyrazolone and the oxicam group; and, more recently, nevirapine and lamotrigine However, there are confounding factors that may impact the identification of a causal drug. For example, oral penicillin, acetaminophen and corticosteroids are usually administered to treat non-specific symptoms that can be premature ones of TEN [3,4]. Food comes into contact with pancreatic and biliary secretions just below this anastomosis, in the small intestine segment known as the common channel. The greater the distance between the Roux limb and the common channel, the less nutritional absorption occurs.

Biliopancreatic diversion, which is frequently performed with the duodenal switch approach, which includes sleeve gastrectomy, is an example of a malabsorptive treatment that imposes less gastric restriction than the Rouxen- Y procedure. Some surgeons do a sleeve gastrectomy as the first stage of a phased treatment, followed by a Roux-en-Y procedure after initial weight loss makes surgery simpler and lowers operational risk. Despite the fact that their design was thought to have a significant bias risk, their summary evaluations, as well as those of two meta-analyses, show that various bariatric surgeries result in a typical weight reduction of 20 to 50 kg, compared to a minor weight increase in medically managed patients [5].

Conclusion

The role of medication metabolism in TEN is unclear; however, certain metabolites, such as hydroxylamine produced from sulphonamide or aromatic antiepileptics, attach to cells fast if they are not cleared correctly by epoxide hydroxylase. When these metabolites are exposed on cell surfaces, they become antigenic and can trigger apoptotic pathways. Despite the rarity of a second episode of TEN, the discovery of a shorter latency between drug exposure and clinical start in a recurrence implies the existence of a main sensitivity mechanism and immunological memory. In fact, TEN survivors are more likely than not to acquire autoimmune disorders such as Systemic Lupus Erythematosus or Sjögren's Syndrome.
