Phosgene Oxime (CX), an urticant or nettle agent categorized as a vesicant, is a potential chemical warfare and terrorist weapon. Its exposure can result in widespread and devastating effects including high mortality due to its fast penetration and ability to cause immediate severe cutaneous injury. It is one of the least studied chemical warfare agents with no effective therapy available. Thus, our goal was to examine the acute effects of CX following its cutaneous exposure in SKH-1 hairless mice to help establish a relevant injury model...

BACKGROUND: Non-melanoma skin cancer includes basal cell carcinoma and squamous cell carcinoma (SCC). Basal cell carcinoma is the most common and least aggressive but in a low percentage of cases, despite appropriate wide surgical margins, it can be aggressive, producing local invasion, recurrences and distance metastasis. SCC has a more aggressive behaviour invading first the skin, the lymph nodes and less frequently produces distance metastasis OBJECTIVE: To identify the characteristics of recurrent SCC and frequency of new SCC after conventional surgical and primary closure or closure delayed until a histological reporting of tumour-free surgical margins, in order to achieve a better surgical option, in our Mexican population...

Fibromodulin (FMOD), an ECM small leucine-rich proteoglycan (SLRP), was reported to promote angiogenesis not only during wound healing, but also in optical and cutaneous angiogenesis-dependent diseases. However, whether it plays important roles in tumor angiogenesis remains unclear. To explore the role of FMOD in tumor angiogenesis of human small cell lung cancer (SCLC), initially the study analyzed the relationship of FMOD expression in cancer tissues of SCLC with clinical characteristics. The analysis revealed that the positive FMOD expression was significantly associated with extensive stage of SCLC and higher vascular density...

BACKGROUND/AIM: Systemic isotretinoin has been widely considered an effective and safe medical treatment for severe and refractory acne for nearly 3 decades. However, it also appears to cause undesirable cutaneous side effects. The aim of this study was to prospectively measure biophysical parameters of skin function among patients with acne vulgaris before and after 3 months of isotretinoin therapy, including pH, temperature, sebum content, skin hydration, and transepidermal water loss...

RATIONALE: Defects in filaggrin and STAT3 are associated with atopic dermatitis (AD) and susceptibility to severe skin infection. METHODS: We evaluated skin infection with the current smallpox vaccine, ACAM-2000, in immunosuppressed mice with combined cutaneous deficiency in filaggrin and STAT3. In parallel, early events post-infection with ACAM-2000 were investigated in cultured keratinocytes in which filaggrin expression was knocked down via siRNA. RESULTS: Immunosuppressed, filaggrin-deficient mice, treated with the topical STAT3 inhibitor Stattic® prior to ACAM-2000 infection, demonstrated rapid weight loss, prolonged vaccinia burden in skin, and dermatitis...

Affective touch and cutaneous pain are two sub-modalities of interoception with contrasting affective qualities (pleasantness/unpleasantness) and social meanings (care/harm), yet their direct relationship has not been investigated. In 50 women, taking into account individual attachment styles, we assessed the role of affective touch and particularly the contribution of the C tactile (CT) system in subjective and electrophysiological responses to noxious skin stimulation, namely N1 and N2-P2 laser-evoked potentials...

Transplantation of bone marrow mesenchymal stem cells (BMSCs) has been considered as a promising strategy for wound healing. However, poor viability of engrafted BMSCs and limited capabilities of differentiation into the desired cell types in wounds often hinder their application. Few studies report the induction of BMSCs differentiation into the skin regeneration related cell types using natural biopolymer, e.g., chitin and its derivative. Here we utilized a chitin nanofibers(CNFs) hydrogel as a directive cue to induce BMSCs differentiation for enhancing cutaneous wound regeneration in the absence of cell-differentiating factors...

The childhood variant of linear IgA bullous dermatosis (LABD) is characterized by blistering lesions of the perineum and perioral area with an annular or "rosette-like" arrangement, in addition to the pathognomonic linear IgA deposits along the cutaneous basement membrane zone (BMZ).(1) The disease mainly occurs in preschool children.(1) However, a handful of neonatal cases have been described, most of them presenting with severe mucosal involvement.(2-8) We report an additional case of neonatal LABD with life-threatening respiratory tract manifestations...

Cutaneous lesions of sarcoidosis present with various manifestations including specific and non-specific cutaneous lesions. Ichthyosiform sarcoidosis is a rare form of cutaneous sarcoidosis, presenting with asymptomatic, adherent, polygonal scales, mainly appearing on the lower limbs.  Ichthyosiform sarcoidosis has a predilection for dark-skinned races, and cases affecting Japanese patients have rarely been reported in English literature.  We herein describe three Japanese cases of ichthyosiform sarcoidosis on the lower limbs...

BACKGROUND: The purpose of this experiment was to investigate the interactions of the local anesthetic lidocaine combined with an agent (serotonin or dopamine) as infiltrative anesthetics. METHODS: Cutaneous analgesia was characterized by the blockade of the cutaneous trunci muscle reflex following 6 skin pinpricks on the rat back. Serotonin or dopamine at producing cutaneous analgesia in a dosage-dependent fashion was compared with lidocaine. Drug-drug interactions were calculated using the isobolographic analysis...

BACKGROUND: The American Joint Committee on Cancer 7th edition (AJCC-7) and Brigham and Women's Hospital (BWH) staging criteria for cutaneous squamous cell carcinoma (cSCC) have not been validated in immunosuppressed patients. OBJECTIVE: To compare the AJCC-7 and BWH staging systems for cSCCs in immunosuppressed patients. METHODS AND MATERIALS: A single-institution retrospective cohort study of cSCCs in immunosuppressed patients. Risks of local recurrence (LR), nodal metastasis (NM), in-transit metastasis, and any poor outcome (PO) were compared among AJCC-7 and BWH tumor T stages...

BACKGROUND: Atypical fibroxanthoma (AFX) is a rare cutaneous spindled cell neoplasm. For both diagnostic and therapeutic purposes, it is important to distinguish AFX from other poorly differentiated tumors, including undifferentiated pleomorphic sarcoma (UPS). OBJECTIVE: The authors aimed to identify the clinical, histologic, and immunohistochemical expression of LN2, ezrin, and CD10 in AFX and UPS tumors. METHODS AND MATERIALS: The authors retrospectively examined the charts of patients with AFX and UPS treated with Mohs micrographic surgery (MMS) at 2 academic institutions...

BACKGROUND: The prognosis of cutaneous melanoma is correlated to histopathologic parameters such as Breslow thickness, the presence of mitosis, ulceration and lymphatic involvement at the moment of the diagnosis. On the other hand, the prognostic value of parameters such as age, sex, and tumor localization are still a matter of debate. We evaluated herein the prognostic factors in melanoma patients during a long term follow- up (60 months). METHODS: Melanoma patients presenting stage IB-III at diagnosis were included...

The 'thermal grill illusion' (TGI) is a unique cutaneous sensation of unpleasantness, induced through the application of interlacing warm and cool stimuli. While previous studies have investigated optimal parameters and subject characteristics to evoke the illusion, our aim was to examine the modulating effect as a conditioning stimulus. A total of 28 healthy control individuals underwent three testing sessions on separate days. Briefly, 15 contact heat stimuli were delivered to the right hand dorsum, while the left palmar side of the hand was being conditioned with either neutral (32 °C), cool (20 °C), warm (40 °C), or TGI (20/40 °C)...

Congenital melanocytic naevi (CMN) are a known risk factor for melanoma, with the greatest risk currently thought to be in childhood. There has been controversy over the years about the incidence, and therefore over clinical management of CMN, due partly to the difficulties of histological diagnosis and partly to publishing bias towards cases of malignancy. Large cohort studies have demonstrated that risk in childhood is related to the severity of the congenital phenotype, not only cutaneous but neuroradiological...
