The permeability barrier plays an important role in numerous skin diseases. Particularly well known is the importance of this barrier in eczema. In irritative-toxic contact dermatitis, the first step in the pathogenesis is the disturbance of the permeability barrier by irritative-toxic noxious substances. Only after damage to the barrier is achieved can irritants and allergens penetrate into the living epidermis. In atopic eczema due to an impaired barrier, allergens penetrate from the environment into the skin and cause or worsen the eczema...

Hepatitis B virus (HBV) infection in pregnant women is very rare in western countries, thus, cutaneous manifestation of HBV infection may be confused with a dermatosis specific of pregnancy. We report a 39-year-old woman who presented in her 20th week of pregnancy with a pruritic rash, which consisted of generalized erythematous plaques, some of them with a purple centre. Serology testing showed acute HBV infection, and a biopsy revealed a superficial and interstitial perivascular inflammatory infiltrate of lymphocytes and eosinophils...

BACKGROUND: Visceral leishmaniasis is not normally expressed in skin. Herein, we describe the case of an HIV-positive patient who developed two unusual skin manifestations during an episode of visceral leishmaniasis. PATIENTS AND METHODS: A 48-year-old female patient consulted initially for infiltrated purpura of all four limbs. Skin biopsy revealed leukocytoclastic vasculitis with Leishman-Donovan bodies. Laboratory tests showed medullary, splenic, gastric and colic involvement, suggesting systemic disease, and enabling visceral leishmaniasis to be diagnosed...

Vemurafenib is a selective inhibitor of the BRAF-kinase approved for the treatment of metastatic melanoma harboring BRAF mutation. Skin toxicity, including maculopapular exanthema, photosensitivity and keratoacanthoma, are the most common treatment-related adverse events of vemurafenib, affecting more than 90% of patients (1,2). It rarely presents with intense severity, with less than 1% of grade-4 toxicities reported in clinical trials (3,4). This article is protected by copyright. All rights reserved.

Hypersensitivity reactions to β-lactam antibiotics are commonly reported. They can be classified as immediate or non-immediate according to the time interval between the last drug administration and their onset. Immediate reactions occur within one hour after the last drug administration and are manifested clinically by urticaria and/or angioedema, rhinitis, bronchospasm, and anaphylactic shock; they may be mediated by specific IgE-antibodies. Non-immediate reactions occur more than one hour after the last drug administration...

BACKGROUND: DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare syndrome triggered by an immunological reaction to certain drugs and which may be life-threatening as a result of the onset of severe organ involvement. It is characterised by a long period from the time of drug therapy to the onset of actual signs. Herein, we report the case of 42-year-old female patient who developed DRESS one month after beginning allopurinol treatment. PATIENTS AND METHODS: A 42-year-old woman was hospitalised for febrile exanthema with facial oedema, polyadenopathy, mononucleosis syndrome, major hypereosinophilia and hepatic cytolysis...

The epidemiology and clinical association of enterovirus (EV) and parechovirus (HPeV) infections, as well as the type-distribution-according-to-age, were determined during a 4-year study period in Spain. During 2010-2013, a total of 21,832 clinical samples were screened for EV and the detection frequency was 6.5% (1,430). Of the total EV-negative samples, only 1,873 samples from 2011 to 2013 were available for HPeV testing. HPeV was detected in 42 (2%) of them. Positive samples were genotyped using PCR and sequencing...

BACKGROUND: Antibiotics are among the most frequent causes of cutaneous adverse drug reactions (CADR); patch testing may be an important tool in their evaluation and management. We assessed the role of patch testing as a diagnostic tool in non-immediate CADR to antibiotics, and evaluated cross-reactivity among them. METHODS: We reviewed data from all patients with non-immediate CADR attributed to antibiotics, which were patch tested between 2000 and 2014 at our dermatology department...

Hippocrates (Island of Kos, 460 B.C.-Larissa, 370 B.C.) is the founder of the most famous Medical School of the classical antiquity. In acknowledgement of his pioneering contribution to the new scientific field of Paediatric Virology, this article provides a systematic analysis of the Hippocratic Corpus, with particular focus on viral infections predominating in neonates and children. A mumps epidemic, affecting the island of Thasos in the 5th century B.C., is described in detail. 'Herpes', a medical term derived from the ancient Greek word 'ἕρπειν', meaning 'to creep' or 'crawl', is used to describe the spreading of cutaneous lesions in both childhood and adulthood...

BACKGROUND: Cutaneous adverse drug reactions frequently present as a benign maculopapular exanthema (MPE) with a rapid healing. Sometimes systemic signs are present, which could represent a more severe or systemic MPE (sMPE) or even be the initial phase of a drug reaction with eosinophilia and systemic symptoms (DRESS). Histopathology associated with MPE, sMPE and DRESS has not been well characterized. OBJECTIVES: To study the cutaneous histopathological changes associated with MPE, sMPE and DRESS...

BACKGROUND: Few studies have been published on the histopathology of cutaneous adverse drug reactions (CADR), and most of these lack information on skin allergological tests. The histopathology of drug reaction with eosinophilia and systemic symptoms (DRESS) is also seldom described. The purpose of our study was to examine six types of well-documented CADR (maculopapular exanthema, DRESS, fixed drug eruption, Stevens-Johnson syndrome, toxic epidermal necrolysis [TEN], and acute generalized exanthematous pustulosis) using histopathology and immunohistochemistry to evaluate the expression of granulysin, a key molecule in TEN...

Scrophularia dentata is an important Tibetan medicinal plant and traditionally used for the treatment of exanthema and fever in Traditional Tibetan Medicine (TTM). However, there is little sequence and genomic information available for S. dentata. In this paper, we report the complete chloroplast genome sequence of S. dentata and it is the first sequenced member of the Sect. Tomiophyllum within Scrophularia (Scrophulariaceae). The gene order and organization of the chloroplast genome of S. dentata are similar to other Lamiales chloroplast genomes...

We report a patient with HIV-associated multicentric Castleman's disease who had recurrent human herpesvirus-8 viremia associated with intermittent febrile exanthema and lymphadenopathy. Although the patient relapsed after single-agent treatment with liposomal doxorubicin, weekly infusions of rituximab led to complete remission even though the reactivation of the Kaposi's sarcoma was unfortunately observed. Rituximab could not only eliminate the accumulation of HHV-8 load but also play a part in the modulation of dysregulated CD20-positive B cells in HIV-associated multicentric Castleman's disease...

BACKGROUND: A multidrug regimen including isoniazid, rifampicin, pyrazinamide, and ethambutol is commonly used as a first-line treatment for tuberculosis. However, these regimens can occasionally result in severe adverse drug reactions such as drug rash with eosinophilia and systemic symptoms (DRESS) syndrome and drug-induced liver injury. The culprit drug and mechanistic basis for the hypersensitive reaction are unknown. OBJECTIVE: To investigate drug-specific T-cell responses in patients with ATD-induced cutaneous hypersensitivity and its underlying mechanism...
