REVIEW
M Mockenhaupt
Among severe drug reactions in children, besides Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), a specific form of hypersensitivity syndrome which is nowadays known as "drug reaction with eosinophilia and systemic symptoms" (DRESS) has to be mentioned. Whereas SJS/TEN is considered one reaction entity of different severity, DRESS has to be distinguished from SJS/TEN but also from other severe exanthems due to multiorgan involvement. Although SJS/TEN is generally referred to as a drug reaction, only about 75% of all cases are actually caused by medications and in children it is only about 50%...

Dry eye is a multifactorial disease comprising a wide spectrum of ocular surface alterations and symptoms of discomfort. In most patients with aqueous-deficient dry eye, pharmaceutical tear substitutes are used to control symptoms and prevent ocular surface damage. However, in severe dry eye conditions caused by cicatricial disorders, such as Stevens-Johnson syndrome and ocular cicatricial mucous membrane pemphigoid, noninvasive treatments are insufficient, and patients are at risk of developing complications that can lead to blindness...

During tissue development, transcription factors bind regulatory DNA regions called enhancers, often located at great distances from the genes they regulate, to control gene expression. The enhancer landscape during embryonic stem cell differentiation has been well characterized. By contrast, little is known about the shared and unique enhancer regulatory mechanisms in different ectodermally derived epithelial cells. Here, we use ChIP-seq to identify domains enriched for histone marks H3K4me3, H3K4me1, and H3K27ac, and define for the first time the super enhancers and typical enhancers active in primary human corneal epithelial cells...

BACKGROUND: Our genome-wide association study documented an association between cold medicine related Stevens-Johnson syndrome / toxic epidermal necrolysis (CM-SJS/TEN) and Ikaros Family Zinc Finger 1 (IKZF1). Few studies examined biological and pathological functions of IKZF1 in mucosal immunity. We hypothesized that IKZF1 contributes to the mucocutaneous inflammation. METHODS: Human skin and conjunctival tissues were obtained for immunohistological studies. Primary human conjunctival epithelial cells (PHCjECs) and adult human epidermal keratinocytes (HEKa) also used for gene expression analysis...

PURPOSE OF REVIEW: When providing accurate clinical diagnosis and genetic counseling in craniosynostosis, the challenge is heightened by knowledge that etiology in any individual case may be entirely genetic, entirely environmental, or anything in between. This review will scope out how recent genetic discoveries from next-generation sequencing have impacted on the clinical genetic evaluation of craniosynostosis. RECENT FINDINGS: Survey of a 13-year birth cohort of patients treated at a single craniofacial unit demonstrates that a genetic cause of craniosynostosis can be identified in one quarter of cases...

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening hypersensitivity reactions mainly caused by drugs. Data on incubation period, hospital stay, and outcome for HIV-positive patients are sparse. Role of corticosteroids in their management is still controversial. METHODS: Indoor cases of SJS, SJS-TEN overlap, and TEN were analyzed for causative drugs, incubation period, a severity-of-illness score for toxic epidermal necrolysis (SCORTEN) score, HIV status, treatment, and outcome...

OBJECTIVES: A previous publication in Chinese leprosy patients showed that the HLA-B*13:01 allele is a strong genetic marker for dapsone-induced drug hypersensitivity reactions, however there are no data describing whether HLA-B*13:01 is a valid marker for prediction of dapsone-induced drug hypersensitivity reactions in other ethnicities or nonleprosy patients. The aim of this study is to investigate whether there is an association between HLA genotypes and dapsone-induced severe cutaneous adverse reactions (SCARs) in nonleprosy patients...

BACKGROUND: Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. CASE: A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of her symptoms was noted, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge...

BACKGROUND/OBJECTIVES: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are medical emergencies. Mainstays of treatment include removal of the offending agent, supportive care, and wound care. The use of immunosuppressive agents such as corticosteroids and intravenous immunoglobulin (IVIg) is controversial. Some case reports and small studies report the successful use of cyclosporin A (CsA) for SJS/TEN in halting disease progression, fostering reepithelialization, and reducing mortality...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse drug reactions. Recent studies have revealed that the prevalence of SJS/TEN is associated with genetic backgrounds, such as polymorphisms in human leukocyte antigens (HLAs). However, non-genetic factors contributing to the etiology of SJS/TEN are largely unknown. This study aimed to assess the involvement of concurrent infection on the pathological states of SJS/TEN, examining the severity of cutaneous symptoms and ocular involvement as well as the time to onset in drug-induced SJS/TEN patients...

BACKGROUND: Despite many studies suggesting an association between human leukocyte antigen (HLA)-B*5801 and allopurinol-induced toxic epidermal necrolysis (TEN) and Stevens-Johnsons syndrome (SJS), the evidence of association in different populations and the degree of association remain uncertain. METHODS: The primary analysis was based on population-control studies. Data were pooled by means of a random-effects model, and sensitivity, specificity, positive likelihood ratios (LR+), negative likelihood ratios (LR-), diagnostic odds ratios (DOR), and areas under summary receiver operating characteristic (SROC) curves (AUC) were calculated...

PURPOSE: It has been reported recently that immune reactions are involved in the pathogenesis of certain types of adverse drug reactions (ADRs). We aimed to determine the associations between infections and drug-induced interstitial lung disease (DILD), rhabdomyolysis, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), or drug-induced liver injury (DILI) using a spontaneous adverse drug event reporting database in Japan. METHODS: The reported cases were classified into three categories (anti-infectious drug group, concomitant infection group, and non-infection group) based on the presence of anti-infectious drugs (either as primary suspected drug or concomitant drug) and infectious disease...

Mycoplasmapneumoniae is a common cause of respiratory infections. Although most cases are mild, some patients have extrapulmonary complications including mucocutaneous eruptions including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and erythemamultiforme (EM). Recently, a new entity, called M. pneumoniae-induced rash and mucositis (MIRM) was described. The authors present a clinical case difficult to classify attending to the classical classification of epidermolytic syndromes that meets the criteria proposed for the diagnosis of MIRM...

Stevens-Johnson syndrome (SJS) is an immune mediated hypersensitivity reaction. Significant involvement of oral, nasal, eye, vaginal, urethral, GI and lower respiratory tract mucous membrane may develop. It is usually a reaction due to a medication or due to an infection. In 95 % of case reports, drugs were found to be an important cause for the development of SJS. In this case report, a 32 year old female reported chief complaint of itch skin eruptions all over the body along with erosive lesions on tongue, lips, buccal mucosa and genital mucosa...

In this report, we present a novel case of pseudomelanoma, similar to that seen in a recurrent/traumatized nevus, in pre-existing nevi in a 36-year-old man a few months after recovering from an episode of severe Stevens-Johnson syndrome. The mechanism responsible for the atypical transformation of these nevi is likely the release of cytokines and growth factors in the microenvironment during the repair/regeneration process. It is important to be aware of this phenomenon, and specific inquiry about potential recent blistering skin disorder in addition to the other causes of trauma should be made when dealing with cases of pseudomelanoma to avoid misdiagnosis...
