Rickettsioses: Cutaneous findings frequently lead to diagnosis - a review.

J Dtsch Dermatol Ges 2018 Dec;16(12):1459-1476

While epidemic typhus caused by Rickettsia prowazekii posed a significant threat in Europe before and throughout World War II due to its high mortality, the condition fortunately no longer plays a significant role. Nevertheless, rickettsioses, such as African tick bite fever, have been increasingly diagnosed in travelers returning from sub-Saharan Africa. Caused by Rickettsia africae, African tick bite fever presents with characteristic cutaneous findings such as eschar (tache noir) and a rash. Read More

Nomenclature of cutaneous vasculitides - German translation of the dermatologic addendum to the 2012 Revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides.

J Dtsch Dermatol Ges 2018 Dec;16(12):1425-1432

Department of Dermatology and Venereology, Innsbruck Medical University, Innsbruck, Austria.

The nomenclature system agreed upon by the Chapel Hill Consensus Conference (CHCC) with respect to the terminology and precise definition of the various types of vasculitis has gained widespread interdisciplinary and international acceptance. As the revised version from 2012 (CHCC 2012) does not address the special features of vasculitis of the skin, it has recently been supplemented with an addendum containing the nomenclature of cutaneous vasculitides (D-CHCC). The present article provides the German translation of the terms and defintions of the D-CHCC as well as additional explanatory comments. Read More

Department of Cutaneous Allergy, St John's Institute of Dermatology, Guy's & St Thomas' NHS Foundation Trust, London, UK.

There is a lack of published data on the role of patch testing in patients with so-called multiple chemical sensitivity (MCS), also known as idiopathic environmental intolerances (IEI). This disputed chronic condition is characterised by symptoms that the affected person attributes to low-level exposures to commonly used chemicals. Symptoms are typically vague and non-specific and may include fatigue, headaches, nausea, dizziness, a sensation of skin burning or pain. Read More

Human polyomavirus 7 (HPyV7)-associated dermatoses: novel molecular mechanism driven by viral activation of 4E-BP1 and MEK-ERK-cJun.

Int J Dermatol 2018 Dec 10. Epub 2018 Dec 10.

Department of Dermatology, University of Texas Medical School, Houston, TX, USA.

A number of pruritic skin conditions arising in immunocompromised patients are associated with viral infection. Recently, human polyomavirus 7 (HPyV7) has been implicated in the pathogenesis of eruptive pruritic parakeratotic and dyskeratotic dermatoses with distinct "peacock plumage" histology. While expression of HPyV7 viral protein, namely small tumor (sT) antigen, is prominent within lesional tissue, the functional role of HPyV7 in cutaneous pathobiology is not yet known. Read More

Prognostic implications of markers of the metabolic phenotype in human cutaneous melanoma.

Br J Dermatol 2018 Dec 7. Epub 2018 Dec 7.

Instituto de Investigación Hospital 12 de Octubre, Universidad Complutense de Madrid, Madrid, Spain.

Background: Reprogramming of energy metabolism to enhanced aerobic glycolysis has been defined as a hallmark of cancer.

Objective: To investigate the role of the mitochondrial proteins, β-subunit of the H -ATP synthase (β-F1-ATPase), and heat-shock protein 60 (HSP60), and the glycolytic markers, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and pyruvate kinase M2 (PKM2), as well as the bioenergetic cellular (BEC) index, in melanoma progression.

Ionizing radiation was used in the past for treatment of several benign cutaneous conditions, and particularly hemangiomas. Even though radiotherapy was generally effective, it significantly augmented the risk for malignancies, resulting in a consequent heavy decline of its use for benign conditions. However, radiation-induced neoplasia is still encountered in adult patients irradiated during childhood or adolescence. Read More

Cannabinoid 2 receptor attenuates inflammation during skin wound healing by inhibiting M1 macrophages rather than activating M2 macrophages.

J Inflamm (Lond) 2018 4;15:25. Epub 2018 Dec 4.

1Department of Forensic Pathology, China Medical University School of Forensic Medicine, No.77, Puhe Road, Shenyang North New Area, Shenyang, 110122 Liaoning Province People's Republic of China.

Background: The anti-inflammatory properties of the cannabinoid 2 receptor (CB2R) in injury and inflammatory diseases have been widely substantiated. Specifically, the anti-inflammatory effect of CB2R may be achieved by regulating macrophage polarisation. Several research findings suggested that the activation of CB2R could attenuate inflammation by reducing pro-inflammatory M1 macrophage polarisation and promoting anti-inflammatory M2 polarisation.

Nature 2018 Dec 10. Epub 2018 Dec 10.

Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA, USA.

Animals and humans display two types of response to noxious stimuli. The first includes reflexive defensive responses that prevent or limit injury; a well-known example of these responses is the quick withdrawal of one's hand upon touching a hot object. When the first-line response fails to prevent tissue damage (for example, a finger is burnt), the resulting pain invokes a second-line coping response-such as licking the injured area to soothe suffering.

Si-Zheng Zhou, Wen-Jin Wang and Shuang-Bai Zhou contributed equally to this work and should be considered co-first authors.

Background: Current rodent models of wound healing and scarring are flawed due to rapid wound contraction and inconspicuous scarring after healing, which is not closely parallel to the physiological process in human. This study was designed to establish a novel model of wound healing and scarring in rats.

Methods: Excisional wounds were generated in rat tail or dorsal skin and assessed in terms of histological changes and wound contraction 2, 10 and 16 days postinjury. Read More

Am J Dermatopathol 2018 Nov 22. Epub 2018 Nov 22.

Department of Pathology, University of Washington School of Medicine, Seattle, WA.

Palisaded encapsulated neuromas (PENs) are benign cutaneous nerve sheath proliferations that typically occur as flesh-colored papules solitarily on the head and neck in adults, with a slight predilection for females. Histopathologically, they are partially or completely encapsulated intradermal nodules with Schwann cells and axons in fascicles separated by clefts. Although these features are often characteristic, the hypercellular variant of PEN can pose a diagnostic challenge in distinguishing between other cellular neural and melanocytic lesions. Read More

Purpose: Postmastectomy radiation therapy is an important component of the multimodality approach to later-stage breast cancers. Unfortunately, despite its proven survival benefits, postmastectomy radiation therapy is deleterious to the skin and soft tissue, causing increased complications and worse aesthetic outcomes after breast reconstruction.There is currently no effective pharmaceutical agent to mitigate the soft tissue fibrosis and hypovascularity associated with soft tissue radiation.

Given the prevalence of cancer and leishmaniasis worldwide, the presence of these two pathologies in the same tissue sample may be merely fortuitous. The clinical outcome of both diseases is under the control of innate and adaptive immunity, and in both cases these progressive diseases are characterized by an impaired host Th1 response. As a consequence, the Th2 cytokine microenvironment occurring in progressive leishmaniasis may potentially promote tumor cell proliferation and vice versa. Read More

Background: Although HLA-B*58:01 is a well-known risk factor for the development of allopurinol-induced severe cutaneous adverse reactions (SCARs), most of the HLA-B*58:01 carriers do not suffer from SCARs despite a long-term use of allopurinol. This suggests that there are other risk factors that determine the fate of HLA-B*58:01 carriers.

Objective: The aim of this study was to investigate the additional genetic factors that increases the risk of allopurinol-induced SCARs in HLA-B*58:01 carriers. Read More
