COVID-19 had a great impact on medical approaches among dermatologist. This systematic review focuses on all skin problems related to COVID-19, including primary and secondary COVID-related cutaneous presentations and the experts recommendations about dermatological managements especially immunomodulators usage issues. Search was performed on PubMed, Scopus, Embase and ScienceDirect. Other additional resources were searched included Cochrane, WHO, Medscape and coronavirus dermatology resource of Nottingham university. The search completed on May 3, 2020. Three hundred seventy-seven articles assigned to the inclusion and exclusion groups. Eighty-nine articles entered the review. Primary mucocutaneous and appendageal presentations could be the initial or evolving signs of COVID-19. It could be manifest most commonly as a maculopapular exanthamatous or morbiliform eruption, generalized urticaria or pseudo chilblains recognized as "COVID toes" (pernio-like acral lesions or vasculopathic rashes). During pandemic, Non-infected non-at risk patients with immune-medicated dermatologic disorders under treatment with immunosuppressive immunomodulators do not need to alter their regimen or discontinue their therapies. At-risk o suspected patients may need dose reduction, interval increase or temporary drug discontinuation (at least 2 weeks). Patients with an active COVID-19 infection should hold the biologic or non-biologic immunosuppressives until the complete recovery occur (at least 4 weeks).

Meta-Analysis
BACKGROUND
This is an update of the Cochrane Review first published in 2010; it includes one additional study. Primary generalised tonic-clonic seizures are a type of generalised seizure. Other types of seizures include: absence, myoclonic, and atonic seizures. Effective control of tonic-clonic seizures reduces the risk of injury and death, and improves quality of life. While most people achieve seizure control with one antiepileptic drug, around 30% do not, and require a combination of antiepileptic drugs.
OBJECTIVES
To assess the effectiveness and tolerability of add-on lamotrigine for drug-resistant primary generalised tonic-clonic seizures.
SEARCH METHODS
For the latest update, we searched these databases on 19 March 2019: Cochrane Register of Studies (CRS) Web, MEDLINE Ovid, and the WHO International Clinical Trials Registry Platform (ICTRP). The CRS includes records from the Cochrane Epilepsy Group Specialized Register, CENTRAL, Embase, and ClinicalTrials.gov. We imposed no language restrictions. We also contacted GlaxoSmithKline, manufacturers of lamotrigine.
SELECTION CRITERIA
Randomised controlled parallel or cross-over trials of add-on lamotrigine for people of any age with drug-resistant primary generalised tonic-clonic seizures.
DATA COLLECTION AND ANALYSIS
We followed standard Cochrane methodology; two review authors independently assessed trials for inclusion, evaluated risk of bias, extracted relevant data, and GRADE-assessed evidence. We investigated these outcomes: (1) 50% or greater reduction in primary generalised tonic-clonic seizure frequency; (2) seizure freedom; (3) treatment withdrawal; (4) adverse effects; (5) cognitive effects; and (6) quality of life. We used an intention-to-treat (ITT) population for all analyses, and presented results as risk ratios (RRs) with 95% confidence intervals (CIs); for adverse effects, we used 99% CIs to compensate for multiple hypothesis testing.
MAIN RESULTS
We included three studies (total 300 participants): two parallel-group studies and one cross-over study. We assessed varied risks of bias across studies; most limitations arose from the poor reporting of methodological details. We meta-analysed data extracted from the two parallel-group studies, and conducted a narrative synthesis for data from the cross-over study. Both parallel-group studies (270 participants) reported all dichotomous outcomes. Participants taking lamotrigine were almost twice as likely to attain a 50% or greater reduction in primary generalised tonic-clonic seizure frequency than those taking a placebo (RR 1.88, 95% CI 1.43 to 2.45; low-certainty evidence). The results between groups were inconclusive for the likelihood of seizure freedom (RR 1.55, 95% CI 0.89 to 2.72; very low-certainty evidence); treatment withdrawal (RR 1.20, 95% CI 0.72 to 1.99; very low-certainty evidence); and individual adverse effects: ataxia (RR 3.05, 99% CI 0.05 to 199.36); dizziness (RR 0.91, 99% CI 0.29 to 2.86; very low-certainty evidence); fatigue (RR 1.02, 99% CI 0.13 to 8.14; very low-certainty evidence); nausea (RR 1.60, 99% CI 0.48 to 5.32; very low-certainty evidence); and somnolence (RR 3.73, 99% CI 0.36 to 38.90; low-certainty evidence). The cross-over trial (26 participants) reported that 7/14 participants with generalised tonic-clonic seizures experienced a 50% or greater reduction in seizure frequency with add-on lamotrigine compared to placebo. The authors reported four treatment withdrawals, but did not specify during which treatment allocation they occurred. Rash (seven lamotrigine participants; zero placebo participants) and fatigue (five lamotrigine participants; zero placebo participants) were the most frequently reported adverse effects. None of the included studies measured cognition. One parallel-group study (N = 153) evaluated quality of life. They reported inconclusive results for the overall quality of life score between groups (P = 0.74).
AUTHORS' CONCLUSIONS
This review provides insufficient information to inform clinical practice. Low-certainty evidence suggests that lamotrigine reduces the rate of generalised tonic-clonic seizures by 50% or more. Very low-certainty evidence found inconclusive results between groups for all other outcomes. Therefore, we are uncertain to very uncertain that the results reported are accurate, and suggest that the true effect could be grossly different. More trials, recruiting larger populations, over longer periods, are necessary to determine lamotrigine's clinical use.

Meta-Analysis
Serious cutaneous adverse drug reactions [i.e., SJS/TEN with severe ocular complications (SOC)] associated with cold medicine (CM) were reported in several studies. To assess the risks of CM-induced SJS/TEN with SOC, systematic review and meta-analysis were employed. Studies investigating associations between HLA genotypes and CM-induced SJS/TEN with SOC were systematically searched in PubMed, Scopus and the Cochrane Library. Overall odds ratios (ORs) with 95% CIs were calculated using a random-effects model to determine these associations. An initial search of the databases identified 24,011 articles, of which 6 studies met the inclusion criteria. In total from all studies, associations between 81 different HLA genotypes and CM-induced SJS/TEN with SOC (i.e., 22 different HLA-A genotypes, 40 different HLA-B genotypes and 19 different HLA-C genotypes) were investigated. Risk factors to develop SJS/TEN with SOC in patients who used CM were identified from our meta-analysis. HLA-A*0206 (OR = 3.90; 95% CI = 1.96-7.77), HLA-A*3303 (OR = 2.28; 95% CI = 1.31-3.97), HLA-B*4403 (OR = 3.27; 95% CI = 1.52-7.03) and HLA-C*0501 (OR = 2.55; 95% CI = 1.19-5.44) were associated with CM-induced SJS/TEN with SOC. With our results demonstrating a significant association between using of CMs and the severe ADR, a genetic testing can be helpful. However, the CMs are commonly used as an over-the-counter drug in practically almost of people in populations worldwide, the genetic screening prior to use of the CMs might not be cost-effective. Nonetheless, for people with a family history of developing the ADRs with a possible involvement of CMs, a genetic screening may be beneficial.

The prevalence of cutaneous adverse events attributable to newly approved anti-cancer drugs has been well reviewed in the dermatologic literature. In contrast, over 75% of US Food and Drug Administration approvals in the past 5 years have been for non-cancer drugs and indications. This represents multiple other categories of approved medications associated with cutaneous adverse reactions. To investigate the cutaneous adverse events associated with these potentially neglected medications, a systematic review was conducted. Two hundred and forty-one medications approved by the Food and Drug Administration between 2013 and 2018 were reviewed and 180 non-oncologic drugs were identified. The prescribing information for each medication was reviewed for the presence of cutaneous adverse events and a supplemental literature search was performed to better characterize any adverse events outlined within the prescribing information. Most reactions were classified as morbilliform, macular, popular, or maculopapular. Fortunately, only a few severe cutaneous adverse reactions were reported, namely in benznidazole, cannabidiol, and sofosbuvir. This review summarizes available data drawn from clinical trials and case reports involving cutaneous adverse events from the 21 non-oncologic medications associated with cutaneous adverse events.

Hydroxychloroquine and chloroquine, also known as antimalarial drugs, are widely used in the treatment of rheumatic diseases and have recently become the focus of attention because of the ongoing COVID-19 pandemic. Rheumatologists have been using antimalarials to manage patients with chronic immune-mediated inflammatory rheumatic diseases for decades. It is an appropriate time to review their immunomodulatory and anti-inflammatory mechanisms impact on disease activity and survival of systemic lupus erythematosus patient, including antiplatelet effect, metabolic and lipid benefits. We also discuss possible adverse effects, adding a practical and comprehensive approach to monitoring rheumatic patients during treatment with these drugs.

AIM
Intramuscular or, more rarely, local drug injection is occasionally followed by immediate local pain, livedoid skin lesions and, some days later, the development of ischemic lesions. This very uncommon but potentially severe reaction, termed Nicolau syndrome, is traditionally associated with bismuth and β-lactam antimicrobials. The aim of this report was to review the literature associating Nicolau syndrome with the administration of non-steroidal anti-inflammatory drugs.
METHODS
The National Library, Excerpta Medica, Web of Science and Cochrane library databases were used.
RESULTS
Sixty-two cases (40 females and 22 males aged from 13 to 81, median 57 years) of Nicolau syndrome were published after 1992. Fifty-three cases occurred after diclofenac. The remaining nine cases were associated with ketoprofen (N = 2), ketorolac (N = 2), phenylbutazone (N = 2), etofenamate (N = 1), ibuprofen (N = 1) and piroxicam (N = 1).
CONCLUSION
Although Nicolau syndrome is extremely uncommon, physicians must be aware of this complication after intramuscular administration of non-steroidal anti-inflammatory drugs and should avoid unnecessary injections.

Tumor necrosis factor (TNF)-α inhibitors increase susceptibility to tuberculosis, but the effect of biologics on susceptibility to leprosy has not been described. Moreover, biologics may play a role in treating erythema nodosum leprosum (ENL). The objectives of this systematic review were to determine whether the development of clinical leprosy is increased in patients being treated with biologics and to assess the use of biologics in treating leprosy reactions. A systematic literature review was completed of patients with leprosy who received treatment with biologics either before or after a diagnosis of leprosy was confirmed. All studies and case reports were included for qualitative evaluation. The search yielded 10 cases (including one duplicate publication) of leprosy diagnosed after initiation of TNF-α inhibitors and four case reports of refractory ENL successfully treated with infliximab or etanercept. An unpublished case of persistent ENL responsive to infliximab is also presented. These data demonstrate that the use of TNF-α inhibitors may be a risk factor for developing leprosy or reactivating subclinical infections. Leprosy can present with skin lesions and arthritis, so leprosy should be considered in patients presenting with these signs before starting treatment with these agents. Leprosy should be considered in patients who develop worsening eruptions and neurologic symptoms during treatment with TNF-α inhibitors. Finally, TNF-α inhibitors appear effective in some cases of refractory ENL.

PURPOSE
Recently, there have been an increased number of reports on levetiracetam (LEV) induced cutaneous adverse drug reactions (CADRs). We aimed to identify and critically evaluate all the descriptive studies on LEV induced-CADRs and to describe the possible clinical manifestations, management, and treatment outcomes of the condition.
METHODOLOGY
PubMed and grey literature databases were searched from inception to June 2019 without any restriction. We also performed a bibliographic search for additional studies. Only descriptive studies on LEV-induced CADRs were included for our review. Study selection, data abstraction and quality assessment were performed by two contributors independently and disagreements were settled through consensus or through discussion with a third reviewer.
RESULTS
Data from 24 out of 88 studies, which included 25 patients (12 female and 13 male) aged from 40 weeks to 73 years, were reviewed. Patients received between 500 mg/day to 3000 mg/day of LEV. Drug reaction with eosinophilia and systemic symptoms syndrome, Steven-Johnson syndrome, toxic epidermal necrolysis, acute generalised exanthematous pustulosis, generalised hyperpigmentation and leucocytoclastic vasculitis were observed among the included patients. Immediate cessation of LEV, providing supportive care and use of topical antihistamines and anti-inflammatory drugs appeared to be the mainstay of management, and all patients were found to have recovered.
CONCLUSION
Clinicians should be aware of the possible CADRs induced by LEV to avoid the development of a potentially fatal condition. Immediate withdrawal of the drug and supporting care seem to be effective in the management of the CADRs.

Drug hypersensitivity reactions (DHRs) are associated with high global morbidity and mortality. Cutaneous T cell-mediated reactions classically occur more than 6 hours after drug administration and include life-threatening conditions such as toxic epidermal necrolysis, Stevens-Johnson syndrome, and hypersensitivity syndrome. Over the last 20 years, significant advances have been made in our understanding of the pathogenesis of DHRs with the identification of human leukocyte antigens as predisposing factors. This has led to the development of pharmacogenetic screening tests, such as HLA-B*57:01 in abacavir therapy, which has successfully reduced the incidence of abacavir hypersensitivity reactions. We have completed a PRISMA-compliant systematic review to identify genetic associations that have been reported in DHRs. In total, 105 studies (5554 cases and 123 548 controls) have been included in the review reporting genetic associations with carbamazepine (n = 31), other aromatic antiepileptic drugs (n = 24), abacavir (n = 11), nevirapine (n = 14), trimethoprim-sulfamethoxazole (n = 11), dapsone (n = 4), allopurinol (n = 10), and other drugs (n = 5). The most commonly reported genetic variants associated with DHRs are located in human leukocyte antigen genes and genes involved in drug metabolism pathways. Increasing our understanding of genetic variants that contribute to DHRs will allow us to improve diagnosis, develop new treatments, and predict and prevent DHRs in the future.

AIMS AND BACKGROUND
It is essential to make sure that vaccines are safe, effective, and of good quality. In the past years, there have been some reports of adverse effects regarding vaccination. One of these adverse effects is the development of Stevens-Johnson syndrome. Stevens-Johnson syndrome is a rare, severe, skin disorder, that usually occurs after medication. In Europe, its estimated incidence is of 2-3 cases/million population/year. Therefore, the aim of this study was to investigate, through a systematic review, the association between vaccination and the development of Stevens-Johnson syndrome.
MATERIALS AND METHODS
We performed a systematic review using PubMed, Scopus and Web of Science databases. We included studies dated between January 2000 and February 2018. The main selection criterion was the reporting of the disease, following vaccination.
RESULTS
Ten studies were selected, from a total of 391 studies. Of these, 5 were case reports, 3 were cohort studies and 2 were case-control. All the studies were regarding cases of Stevens-Johnson syndrome after vaccination. The selected studies reported cases following vaccines such as influenza vaccine, smallpox, anthrax and tetanus vaccine, MMR vaccine, varicella vaccine, DTaP-IPV vaccine or rabies vaccine. None of the cohort studies reported statistically significant associations between vaccination and the syndrome. In the case-control studies, it was not observed significant increased risk for the Stevens-Johnson syndrome following the administration of vaccines. Regarding the case reports, there was not sufficient evidence to form a positive association between these two factors, and more studies are needed.
CONCLUSIONS
In this review it was not possible to establish a positive relation between vaccination and the development of Stevens-Johnson syndrome.
