Abstract
SCARs are rare and life-threatening hypersensitivity reactions. In general, the increased duration of hospital stays and the associated cost burden are common issues, and in the worst-case scenario, they can result in mortality. SCARs are delayed T cell-mediated hypersensitivity reactions. Recovery can take from 2 weeks to many months after dechallenging the culprit drugs. Genetic polymorphism of the HLA genes may change the selection and presentation of antigens, allowing toxic drug metabolites to initiate immunological reactions. However, each SCARs has a different onset latency period, clinical features, or morphological pattern. This explains that, other than HLA mutations, other immuno-pathogenesis may be involved in drug-induced severe cutaneous reactions. This review will discuss the clinical morphology of various SCARs, various immune pathogenesis models, diagnostic criteria, treatments, the association of various drug-induced reactions and susceptible alleles in different populations, and the successful implementation of pharmacogenomics in Thailand for the prevention of SCARs.

Abstract
This article provides an overview of the pathogenesis and risk factors associated with antiepileptic drug (AED) hypersensitivity reactions, provides prescribing guidelines that may minimize the risk of antiepileptic induced rashes, and discusses treatment options for rashes. Articles indexed in PubMed, Science Citation, and Google Scholar (January 1946-March 2019) were systematic searched using the following key terms: hypersensitivity, rash, antiepileptic, epilepsy, cross-sensitivity, desensitization, patch testing and supplemented with our clinical experiences. Additional references were identified from a review of literature citations. AEDs are associated with cutaneous adverse reactions. Aromatic AEDs and higher titration rates are associated with increased risk of hypersensitivity reaction. Patient characteristics, underlying health conditions, and genetic variations may increase the likelihood of a hypersensitivity reaction. Once a hypersensitivity reaction occurs, the likelihood of cross sensitivity to another AED increases, especially among other aromatic AEDs. Withdrawal of the causal agent and initiation of a lower risk agent usually leads to resolution of symptoms. Desensitization protocols may be an option for patients whose seizures only respond to the AED causing the rash.

Abstract
Cutaneous adverse drug reactions comprise a significant proportion of all adverse drug reactions. They may mimic other dermatologic or systemic illnesses and may cause significant morbidity or mortality. Seven morphologic groups encompass the most commonly encountered cutaneous drug reaction syndromes: exanthematous (maculopapular), dermatitic/eczematous, urticarial, pustular, blistering, purpuric, and erythrodermic. Drug reactions may have significant downstream consequences for the older individual.

Abstract
BACKGROUND In Vietnam, we observed a high incidence of carbamazepine (CBZ)-induced severe cutaneous adverse drug reactions (SCARs)-Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), and drug-induced hypersensitivity rash with eosinophilia and systemic symptoms (DRESS). In other Asian countries, HLA-B(*)1502 is an established risk factor for SCARs. OBJECTIVE The aim of our study was to determine the frequency of HLA-B(*)1502 in SCARs patients at a large University Medical Center in Hanoi, Vietnam. METHODS Thirty-eight cases of SCARs caused by CBZ and 25 patients with epilepsy tolerating CBZ were enrolled in a case-controlled study. Clinical manifestations and laboratory findings were recorded for each subject. Genomic DNA was isolated using the QIAamp DNA purification system. The combination of polymerase chain reaction and sequence specific oligonucleotide probes with the Luminex 100×MAP flow cytometry dual laser system was then used to quantitate fluorescently labelled oligonucleotides attached to colour-coded microbeads. RESULTS Cases comprised 20 SJS (52.6%), 7 TEN (18.4%), 8 overlap syndrome (21.1%), and 3 DRESS patients (7.9%). A strong association between HLA B(*)1502 and bullous skin reactions such as SJS/TEN and overlap was confirmed with an odds ratio (OR) of 33.78 (95% confidence interval [CI], 7.55-151.03), p < 0.0001, Sensitivity 91.4%, Specificity 76.0%, positive predictive value 84.2%, and negative predictive value 86.4%. We did not, however, observe any correlation between the presence of this allele and CBZ-induced nonbullous skin reactions (DRESS) (OR, 6.33; 95% CI, 0.48-82.74; p = 0.1592). CONCLUSION Our results indicate the presence of HLA-B(*)1502 in Vietnamese is a pharmacogenetic risk factor for developing CBZ-induced SJS/TEN.

Abstract
BACKGROUND Epilepsy is a chronic neurological disease which affects about 1% of the human population. There are 50 million patients in the world suffering from this disease and 2 million new cases per year are observed. The necessary treatment with antiepileptic drugs (AEDs) increases the risk of adverse reactions. In case of 15% of people receiving AEDs, cutaneous reactions, like maculopapular or erythematous pruritic rash, may appear within four weeks of initiating therapy with AEDs. METHODS This study involved 300 epileptic patients in the period between September 1989 and September 2009. A cutaneous adverse reaction was defined as a diffuse rash, which had no other obvious reason than a drug effect, and resulted in contacting a physician. RESULTS Among 300 epileptic patients of Neurological Practice in Kielce (132 males and 168 females), a skin reaction to at least one AED was found in 30 patients. As much as 95% of the reactions occurred during therapies with carbamazepine, phenytoin, lamotrigine or oxcarbazepine. One of the patients developed Stevens-Johnson syndrome. CONCLUSION Some hypersensitivity problems of epileptic patients were obviously related to antiepileptic treatment. Among AEDs, gabapentin, topiramate, levetiracetam, vigabatrin, and phenobarbital were not associated with skin lesions, although the number of patients in the case of the latter was small.

Abstract
Geriatric dermatoses are a challenging job for the physician in terms of diagnosis, management, and followup. Since skin of the elderly population is going through a lot of changes from both an intrinsic and extrinsic point of view, it is imperative for the physician to have a better understanding of the pathophysiology of geriatric skin disorders and their specific management, which differs slightly from an adult population. This review focuses on a brief introduction to the pathophysiological aspects of skin disorders in elderly, the description of some common geriatric skin disorders and their management and the new emerging role of psychodermatological aspects of geriatric dermatoses is also discussed. At the end, ten multiple choice questions are also added to further enhance the knowledge base of the readers.

Abstract
In everyday clinical practice, almost all physicians come across many instances of suspected adverse cutaneous drug reactions (ACDR) in different forms. Although such cutaneous reactions are common, comprehensive information regarding their incidence, severity and ultimate health effects are often not available as many cases go unreported. It is also a fact that in the present world, almost everyday a new drug enters market; therefore, a chance of a new drug reaction manifesting somewhere in some form in any corner of world is unknown or unreported. Although many a times, presentation is too trivial and benign, the early identification of the condition and identifying the culprit drug and omit it at earliest holds the keystone in management and prevention of a more severe drug rash. Therefore, not only the dermatologists, but all practicing physicians should be familiar with these conditions to diagnose them early and to be prepared to handle them adequately. However, we all know it is most challenging and practically difficult when patient is on multiple medicines because of myriad clinical symptoms, poorly understood multiple mechanisms of drug-host interaction, relative paucity of laboratory testing that is available for any definitive and confirmatory drug-specific testing. Therefore, in practice, the diagnosis of ACDR is purely based on clinical judgment. In this discussion, we will be primarily focusing on pathomechanism and approach to reach a diagnosis, which is the vital pillar to manage any case of ACDR.

Abstract
Strontium ranelate is a relatively new drug used as a second-line treatment for osteoporosis, often targeted at older patients. It is known to cause skin rash and rarely drug reaction with eosinophilia and systemic symptoms, but there are no reports of exfoliative dermatitis as a reaction in the literature. We present the first two cases of this adverse effect of the drug, combined with eosinophilia but no systemic symptoms. We illustrate the significant morbidity involved and use of systemic steroid treatment required, highlighting the need for awareness of this reaction in medical and particularly in elderly care communities.

Abstract
Chronic pruritus, one of the main symptoms in dermatologic diseases, is often intractable and has a high impact on a patient´s quality of life. In addition to dermatologic disorders, chronic pruritus is associated with systemic and neurologic, as well as psychologic, diseases. Aging skin is considered to be more susceptible to pruritic disorders. Thus, owing to demographic changes, pruritus is becoming more prevalent. The elderly are often afflicted with comorbidities and polypharmacy, which can complicate diagnosis and therapy. In this review we present a rational work-up adapted to the special premises and needs of geriatric patients. This may facilitate the choice of suitable therapeutic regimens.

Abstract
Drug-induced adverse reactions (ADR) include any undesirable pharmacological effect that occurs following drug administration at therapeutic doses. The appearance of ADR significantly limits the use of drugs in as much as their clinical symptoms may range from very mild discomfort such as cutaneous rash, up to very severe, or even fatal tissue necrolysis such as the Stevens Johnson syndrome.One of the most frequently involved organ during ADR is the skin. Drug-induced cutaneous reactions (CDR) incidence is variable but they may appear in 2-3% of ambulatory patients, and it may increase to 10-15% when patients are hospitalized, or even be as high as 60% when co morbidity includes the presence of virus, bacteria, or parasites.Due to the fact that skin is one of the organs most frequently involved in ADR, in this work we analyze and propose a mechanism by which epidermal dendritic cells operating as the sentinels of the skin neuro-immune-endocrine system may contribute to CDR via either immunogenic or tolerogenic immune responses towards drugs, whenever they are administered topic or systemically.

Abstract
Aging skin undergoes progressive degenerative change. Structural and physiologic changes that occur as a natural consequence of intrinsic aging combined with the effects of a lifetime of ongoing cumulative extrinsic damage and environment insult (e.g. overexposure to solar radiation) can produce a marked susceptibility to dermatologic disorders in the elderly. As skin ages, the vasculature progressively atrophies. The supporting dermis also deteriorates, with collagen and elastin fibers becoming sparse and increasingly disordered. These changes leave the elderly increasingly susceptible to both vascular disorders such as stasis dermatitis and skin injuries such as pressure ulcers and skin tears, with a steadily decreasing ability to effect skin repair. A parallel erosion of normal immune function produces higher levels of autoimmune skin disorders such as bullous pemphigoid, benign mucous membrane pemphigoid, paraneoplastic pemphigoid, and pemphigus vulgaris. Lichen sclerosus, an autoimmune disorder often occurring in the genital area in older women, is not common but is an important development because of the potential for substantial discomfort as well as serious complications. The prevalence of polypharmacy in this population increases the risk for autoimmune drug reactions, and diagnosis should be undertaken with an awareness that polypharmacy in this population creates a greatly increased susceptibility to drug eruptions that can mimic other cutaneous disorders. Immunologic senescence in the elderly also sets the stage for potential reactivation of the Varicella zoster virus, in which initial dermatologic involvement expands into the major sensory ganglia. Known as shingles, this disorder can be excruciatingly painful with the potential to cause blindness if the optic nerve becomes involved. Dermatoses such as xerosis, pruritus, and eczema are also widespread in the elderly, create substantial suffering in those afflicted, and often prove recalcitrant to treatment. Individual susceptibility to specific types of contact dermatitis changes over the lifetime, and seborrheic dermatitis is substantially more prevalent in the elderly. It is not uncommon for older patients to have multiple impairments, with the potential for cognitive dysfunction as well as impaired vision, hearing, or mobility. In addition, they may not have adequate housing or nutrition, or the financial resources necessary for adequate compliance. Physicians must take into consideration the patient's physical ability to comply with the recommended therapy as well as socioeconomic factors that may impact on compliance. Simple topical regimens are preferable wherever possible in order to maximize compliance and, therefore, efficacy. Extra effort may be necessary to ensure that instructions are accurately followed and that ongoing compliance with the regimen prescribed is actually achieved. Management of dermatologic disorders in the elderly is often less than optimal, due to the fact that the special needs and limitations of this population are not adequately considered. Treatments should consider the intrinsic differences between younger and older patients that may impact on diagnosis and therapy choice. The aged patient is often afflicted with numerous co-morbidities that can influence the choice of therapy. Skin integrity in the elderly is compromised, and safety concerns are increased with the long-term use of any medication prescribed. In addition, the prevalence of polypharmacy in the aged population substantially increases the risk of cutaneous drug reactions, which can profoundly complicate accurate diagnosis of dermatologic disorders. The aged population also needs to be more closely monitored because of increased fragility of the skin and the physical limitations that may hinder compliance with prescribed regimens.

Abstract
PURPOSE Cutaneous adverse reactions from antiepileptic drugs (AEDs) are common, but have received little scientific attention from a clinical point of view. We wanted to study the incidence of skin reactions of current AEDs and to explore their relation to clinical parameters such as gender, age, and learning disability. METHODS Consecutive patients with epilepsy were studied retrospectively. A detailed survey of medical records concerning all treatment with AEDs was performed. RESULTS A total of 663 patients were included with altogether 2,567 exposures to 15 different AEDs. Skin reactions were found in 14% of the patients and in 5% of the exposures. Ninety-seven percent of the reactions occurred to either carbamazepine (CBZ, 11%), phenytoin (PHT, 8%), lamotrigine (LTG, 8%), oxcarbazepine (8%), or phenobarbital (2%). Skin reactions developed significantly more often in females than in males (19% vs. 8%), and significantly less often in patients with learning disability than in other patients (7% vs. 16%). These differences were significant for CBZ, PHT, and LTG when analyzed separately. Females displayed higher rash frequency during the reproductive years, while men experienced less frequent rash in the same phase of life. CONCLUSIONS Fertile females have a higher risk for skin reactions compared to males, probably due to hormonal factors. Patients with learning disability appeared to have a lower risk than other patients in this study. Hygiene factors may possibly be underlying.
