Abstract
We investigated the extent and severity of groundwater arsenic (As) contamination in five blocks in Patna district, Bihar, India along with As in biological samples and its health effects such as dermatological, neurological and obstetric outcome in some villages. We collected 1365 hand tube-well water samples and analyzed for As by the flow injection hydride generation atomic absorption spectrometer (FI-HG-AAS). We found 61% and 44% of the tube-wells had As above 10 and 50 μg/l, respectively, with maximum concentration of 1466 μg/l. Our medical team examined 712 villagers and registered 69 (9.7%) with arsenical skin lesions. Arsenical skin lesions were also observed in 9 children of 312 screened. We analyzed 176 biological samples (hair, nail and urine). Out of these, 69 people had arsenical skin lesions and rest without skin lesions. We found 100% of the biological samples had As above the normal levels (concentrations of As in hair, nail and urine of unexposed individuals usually ranges from 20 to 200 μg/kg, 20-500 μg/kg and <100 μg/l, respectively), indicating many people are sub-clinically affected. Arsenical neuropathy was observed in 40.5% of 37 arsenicosis patients with 73.3% prevalence for predominant sensory neuropathy and 26.7% for sensor-motor. Among patients, different clinical and electrophysiological neurological features and abnormal quantitative sensory perception thresholds were also noted. The study also found that As exposed women with severe skin lesions had adversely affected their pregnancies. People including children in the affected areas are in danger. To combat As situation in affected areas, villagers urgently need (a) provision of As-safe water for drinking and cooking, (b) awareness about the danger of As toxicity, and (c) nutritious food.

Abstract
Epidermal growth factor receptor inhibition is a good target for the treatment of lung, colon, pancreatic and head and neck cancers. Epidermal growth factor receptor-tyrosine kinase inhibitor was first approved for the treatment of advanced lung cancer in 2002. Epidermal growth factor receptor-tyrosine kinase inhibitor plays an essential role in the treatment of cancer, especially for patients harbouring epidermal growth factor receptor activating mutation. Hence, skin toxicity is the most concerning issue for the epidermal growth factor receptor-tyrosine kinase inhibitor treatment. Skin toxicity is bothersome and sometimes affects the quality of life and treatment compliance. Thus, it is important for physicians to understand the background and how to manage epidermal growth factor receptor-tyrosine kinase inhibitor-associated skin toxicity. Here, the author reviewed the mechanism and upfront preventive and reactive treatments for epidermal growth factor receptor inhibitor-associated skin toxicities.

Abstract
DHA Ethyl Ester (DHA-EE) is a 90% concentrated ethyl ester of docosahexaenoic acid manufactured from the microalgal oil. The objective of the 9-month study was to evaluate safety of DHA-EE administered to beagle dogs at dose levels 150, 1000 and 2000 mg/kg bw/day by oral gavage and to determine reversibility of any findings after a 2-month recovery period. DHA-EE was well tolerated at all doses. There were observations of dry flaky skin with occasional reddened areas at doses ≥1000 mg/kg bw/day. These findings lacked any microscopic correlate and were no longer present after the recovery period. There were no toxicologically relevant findings in body weights, body weight gains, food consumption, ophthalmological examinations, and ECG measurements. Test article-related changes in hematology parameters were limited to decreases in reticulocyte count in the high-dose males and considered non-adverse. In clinical chemistry parameters, dose-related decreases in cholesterol and triglycerides levels were observed at all doses in males and females and attributed to the known lipid-lowering effects of DHA. There were no effects on other clinical chemistry, urinalysis or coagulation parameters. There were no abnormal histopathology findings attributed to test article. The No-Observable-Adverse-Effect Level of DHA-EE was established at 2000 mg/kg bw/day for both genders.

Abstract
BACKGROUND The HLA-B*58:01 allele is associated with allopurinol-induced severe cutaneous adverse drug reactions (sCADR) in certain geographic regions, but the diversity of the correlation is large. In addition, the currently available HLA-B*58:01 testing methods are too laborious for use in routine clinical detection. The objective of this study was to develop a new, convenient method for the detection of HLA-B*58:01 and to investigate the association of HLA-B*58:01 with allopurinol-induced sCADR in a Han Chinese population. METHODS A new method combining sequence-specific primers (SSP) and TaqMan probe amplification was developed in this study and was used to detect the HLA-B*58:01 in 48 allopurinol-induced sCADR, 133 allopurinol-tolerant, and 280 healthy individuals. The accuracy, sensitivity, and specificity were assessed by a commercial PCR-SSP HLA-B typing kit. The low limit of detection was detected by serial dilution of an HLA-B*58:01-positive DNA template. RESULTS The new method successfully identified HLA-B*58:01 in thousands of HLA-B alleles, and the results for 344 DNA samples were perfectly concordant with the results of the commercial PCR-SSP HLA-B kit. The analytical sensitivity is 100% and the specificity is over 99%. The low limit of detection of this assay is 100 pg DNA, which was 10 times more sensitive than the commercial PCR-SSP kit. HLA-B*58:01 was present in 93.8% of the patients with sCADR, 7.5% of the allopurinol-tolerant patients, and 12.1% of the healthy controls. The frequency of HLA-B*58:01 was significantly higher in the sCADR group than in the control group (p<0.0001). However, there was no significant difference between the allopurinol-tolerant and control groups (p=0.1547). CONCLUSIONS HLA-B*58:01 has a strong association with allopurinol-induced sCADR in Han Chinese. The newly developed method is reliable for HLA-B*58:01 detection prior to allopurinol therapy.

Abstract
With increasing numbers of patients with unresectable locoregionally advanced (LA) head and neck squamous cell carcinoma (HNSCC) receiving cetuximab/radiotherapy (RT), several guidelines on the early detection and management of skin-related toxicities have been developed. Considering the existing management guidelines for these treatment-induced conditions, clinical applicability and standardization of grading methods has remained a cause of concern globally, particularly in Asian countries. In this study, we attempted to collate the literature and clinical experience across Asian countries to compile a practical and implementable set of recommendations for Asian oncologists to manage skin- and mucosa-related toxicities arising from different types of radiation, with or without the addition of cetuximab or chemotherapy. In December 2013, an international panel of experts in the field of head and neck cancer management assembled for an Asia-Pacific head and neck cancer expert panel meeting in China. The compilation of discussion outcomes of this meeting and literature data ultimately led to the development of a set of recommendations for physicians with regards to the approach and management of dermatological conditions arising from RT, chemotherapy/RT and cetuximab/RT, and similarly for the approach and management of mucositis resulting from RT, with or without the addition of chemotherapy or cetuximab. These recommendations helped to adapt guidelines published in the literature or text books into bedside practice, and may also serve as a starting point for developing individual institutional side-effect management protocols with adequate training and education.

Abstract
A 40-year-old female patient was referred to the department of Dermatology with subcutaneous nodules and ulcers years after starting with immunotherapy injections (Purethal) for hay fever. The skin reaction appeared to be due to aluminium hydroxide, which is used as an adjuvant to many injections and vaccins. Aluminium hydroxide can cause delayed granulomatous contact dermatitis or foreign body reactions.

Abstract
The use of multikinase inhibitors (MKI) in oncology, such as sorafenib, is associated with a cutaneous adverse event called hand-foot skin reaction (HFSR), in which sites of pressure or friction become inflamed and painful, thus significantly impacting quality of life. The pathogenesis of MKI-induced HFSR is unknown, and the only available treatment options involve dose reduction or discontinuation of therapy, which have negative effects on primary disease management. To investigate the underlying mechanisms by which sorafenib promotes keratinocyte cytotoxicity and subsequent HFSR induction, we performed a transporter-directed RNAi screen in human epidermal keratinocytes and identified SLC22A20 (OAT6) as an uptake carrier of sorafenib. Further investigations into the intracellular mechanism of sorafenib activity through in situ kinome profiling identified the mitogen-activated protein kinase MAP3K7 (TAK1) as a target of sorafenib that induces cell death. Finally, we demonstrate that sorafenib induced keratinocyte injury in vivo and that this effect could be reversed by cotreatment with the OAT6 inhibitor probenecid. Collectively, our findings reveal a novel pathway that regulates the entry of some MKIs into keratinocytes and explains the basis underlying sorafenib-induced skin toxicity, with important implications for the therapeutic management of HFSR.

Abstract
BACKGROUND Consumption of arsenic-contaminated drinking water adversely affects health. There is interindividual variation in arsenic metabolism efficiency, partially due to genetic variation in the arsenic methyltransferase (AS3MT) gene region. OBJECTIVES The goal of this study was to assess the overall contribution of genetic factors to variation in arsenic metabolism efficiency, as measured by the relative concentration of dimethylarsinic acid (DMA%) in urine. METHODS Using data on genome-wide single nucleotide polymorphisms (SNPs) and urinary DMA% for 2,053 arsenic-exposed Bangladeshi individuals, we employed various SNP-based approaches for heritability estimation and polygenic modeling. RESULTS Using data on all participants, the percent variance explained (PVE) for DMA% by all measured and imputed SNPs was 16% (p = 0.08), which was reduced to 5% (p = 0.34) after adjusting for AS3MT SNPs. Using information on close relatives only, the PVE was 63% (p = 0.0002), but decreased to 41% (p = 0.01) after adjusting for AS3MT SNPs. Regional heritability analysis confirmed 10q24.32 (AS3MT) as a major arsenic metabolism locus (PVE = 7%, p = 4.4 × 10(-10)), but revealed no additional regions. We observed a moderate association between a polygenic score reflecting elevated DMA% (composed of thousands of non-AS3MT SNPs) and reduced skin lesion risk in an independent sample (p < 0.05). We observed no associations for SNPs reported in prior candidate gene studies of arsenic metabolism. CONCLUSIONS Our results suggest that there are common variants outside of the AS3MT region that influence arsenic metabolism in Bangladeshi individuals, but the effects of these variants are very weak compared with variants near AS3MT. The high heritability estimates observed using family-based heritability approaches suggest substantial effects for rare variants and/or unmeasured environmental factors.

Abstract
BACKGROUND The current study evaluates the mortality of 2,354 workers first employed at a Baltimore chromate production plant between 1950 and 1974. METHODS The National Death Index (NDI Plus) was used to determine vital status and cause of death. Cumulative chromium (VI) exposure and nasal and skin irritation were evaluated as risk factors for lung cancer mortality. RESULTS There are 91,186 person-years of observation and 217 lung cancer deaths. Cumulative chromium (VI) exposure, nasal irritation, nasal perforation, nasal ulceration, and other forms of irritation (e.g., skin irritation) were associated with lung cancer mortality. CONCLUSION Cumulative chromium (VI) exposure was a risk factor for lung cancer death. Cancer deaths, other than lung cancer, were not significantly elevated. Irritation may be a possible mechanism for chromium (VI)-induced lung cancer.

Abstract
OBJECTIVES Fixed-dose combination formulations, which simplify the administration of drugs and prevent the development of drug resistance, have been recommended as a standard anti-tuberculosis treatment regimen. However, the composition and dosage recommendations for fixed-dose combination formulations differ from those for separate formulations. Thus, questions about the effectiveness and side effects of combination formulations remain. The aim of this study was to compare the safety and efficacy of these two types of anti-tuberculosis regimens for pulmonary tuberculosis treatment. METHOD A prospective, randomized controlled study was conducted using the directly observed treatment short-course strategy. Patients were randomly allocated to one of two short-course regimens. One year after completing the treatment, these patients' outcomes were analyzed. ClinicalTrials.gov: NCT00979290. RESULTS A total of 161 patients were enrolled, 142 of whom were evaluable for safety assessment. The two regimens had a similar incidence of adverse effects. In the per-protocol population, serum bilirubin concentrations at the peak level, at week 4, and at week 8 were significantly higher for the fixed-dose combination formulation than for the separate formulations. All patients had negative sputum cultures at the end of the treatment, and no relapse occurred after one year of follow-up. CONCLUSIONS In this randomized study, transient higher serum bilirubin levels were noted for the fixed-dose combination regimen compared with the separate formulations during treatment. However, no significant difference in safety or efficacy was found between the groups when the directly observed treatment short-course strategy was used.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a connective tissue disorder characterised by the development of skin fibrosis. Our current understanding of the disease pathogenesis is incomplete and the study of SSc is hindered, at least partially, by a lack of animal models that fully replicate the complex state of human disease. Murine model of bleomycin-induced dermal fibrosis encapsulates important events that take place early in the disease course. METHODS To characterise the optimum in vivo parameters required for the successful induction of dermal fibrosis we subjected three commonly used mouse strains to repeated subcutaneous bleomycin injections. We aimed to identify the effects of genetic background and gender on the severity of skin fibrosis. We used male and female Balb/C, C57BL/6, and DBA/2 strains and assessed their susceptibility to bleomycin-induced fibrosis by measuring dermal thickness, hydroxyproline/collagen content and number of resident myofibroblasts, all of which are important indicators of the severity of skin fibrosis. All data are expressed as mean values ± SEM. The Mann-Whitney U test was used for statistical analysis with GraphPad Prism 6.04 software. RESULTS Dermal fibrosis was most severe in Balb/C mice compared to C57BL/6 and DBA/2 suggesting that Balb/C mice are more susceptible to bleomycin-induced fibrosis. Analysis of the effect of gender on the severity of fibrosis showed that male Balb/C, C57BL/6, DBA/2 mice had a tendency to develop more pronounced fibrosis phenotype than female mice. Of potential importance, male Balb/C mice developed the most severe fibrosis phenotype compared to male C57BL/6 and male DBA/2 as indicated by significantly increased number of dermal myofibroblasts. CONCLUSION Our study highlights the importance of genetic background and gender in the induction of murine dermal fibrosis. Robust and reproducible animal models of fibrosis are important research tools used in pharmacological studies which may lead to better understanding of the pathogenesis of fibrotic diseases and assist in identification of new drugs.

Abstract
Skin lesions and cancer are known manifestations of chronic exposure to arsenic contaminated drinking water. Epidemiologic data primarily comes from regions with exposures 1-2 orders of magnitude above the current World Health Organization (WHO) guidelines of 10 μg/L. Emerging evidence indicates that more common exposures may also be related to both noncancerous and cancerous changes to the skin. In this review, we focus on the body of epidemiologic literature that encompasses exposures within the WHO guidelines, excluding studies that lacked individual exposure estimates and case reports. For skin lesions and skin cancers, 15 and 10 studies were identified that met our criteria, respectively. For skin lesions, a consistent dose-response relationship with water arsenic has been observed, with increased risk evident at low- to moderate-dose exposure. Of the larger studies of specific histologic types of skin cancers, although with differing exposure definitions, there was evidence of dose-related relationships with both basal cell carcinomas and squamous cell carcinomas. The effect of arsenic exposure on skin lesion risk is likely modified by genetic variants that influence arsenic metabolism. Accumulating evidence suggests that arsenic may increase risk of skin lesions and skin cancers at levels not previously considered harmful, and that genetic factors may influence risk.

Abstract
BACKGROUND Quality of life (QOL) can be affected by diseases, disasters, and exposure events to environmental factors. However, whether health-related QOL (HRQOL) might be adversely affected by exposure to dioxin-like chemicals 30 years ago is unknown. METHODS We studied people who were poisoned to polychlorinated biphenyls (PCBs) and dibebenzofurans (PCDFs) due to ingestion of contaminated rice oil in 1979 in central Taiwan, and were called Yucheng (oil-disease in Chinese) people. In 2008, we conducted a survey in 1305 exposed people by mailed questionnaire, which included HRQOL by World Health Organization (WHO) quality of life-BREF (WHOQOL-BREF) Taiwanese version. A total of 240 Yucheng subjects aged 18-65 years satisfactorily completed the Questionnaire. For comparison, we obtained information from the database of 2001 National Health Survey conducted by the National Health Research Institute and Bureau of Health Promotion, Department of Health, Taiwan. Data from age-, sex-, and county-matched background individuals were extracted using 1:3 match. HRQOL among Yucheng people with/without skin manifestation and unexposed referents were compared, while adjusting for other factors by multiple regression analyzes. RESULTS The Yucheng people had significantly reduced scores in the physical, psychological, social, and environmental domains as compared to the referents. Those with skin manifestations were more severely affected than those with no skin manifestations, suggesting a dose-related effect on QOL in exposed people. CONCLUSION We show for the very first time that poisoning due to persistent organic pollutants PCBs and PCDFs can affect QOL 30 years after the exposure, especially among those most severely poisoned.

Abstract
Pediatric oncology patients can present with various skin lesions related to both primary disease and immunosuppressive treatments. This study aimed to evaluate the cutaneous side effects of chemotherapy in pediatric oncology patients. Sixty-five pediatric oncology patients who were scheduled to undergo chemotherapy from May 2011 to May 2013 were included in the study. Three patients were excluded from the results, as 2 patients died during treatment and 1 patient withdrew from the study; therefore, a total of 62 patients were evaluated for mucocutaneous findings. Patients were grouped according to their oncological diagnoses and a statistical analysis was performed. There was no statistical significance in the incidence of cutaneous side effects of chemotherapy among the different diagnostic groups. Awareness among dermatologists of the possible cutaneous side effects of chemotherapy in pediatric patients and their causes can promote early diagnosis and treatment in this patient population.

Abstract
BACKGROUND Fosaprepitant may be associated with infusion site adverse events (AEs), and these adverse events possibly vary according to chemotherapy regimen. PATIENTS AND METHODS 267 oncology patients who were administered anthracycline- or cisplatin-based regimens were retrospectively studied. Multivariate logistic regression was performed in stratified analyses to evaluate potential regimen-specific effects of fosaprepitant. RESULTS 41.7% of patients administered fosaprepitant experienced infusion site AEs. On the other hand, only 10.9% of patients administered aprepitant experienced AEs. Multivariate analysis showed a statistically significant overall increased risk of infusion site reaction associated with fosaprepitant (p<0.001), but when evaluated separately according to chemotherapy regimen, this relationship appeared to be largely confined to patients receiving an anthracycline-based regimen (OR=12.95, 95%CI=5.74-29.20). No association was observed among patients on cisplatin-based regimens. A test for interaction was statistically significant (p=0.001). CONCLUSION Fosaprepitant is associated with an elevated risk of infusion site reaction in patients receiving anthracyclines.

Abstract
The flower industry is among the most important export industries in Ethiopia, employing more than 50,000 workers. The working conditions and health status among workers in Ethiopian flower industry are not documented. A questionnaire-based interview was conducted among 213 flower industry workers from 3 flower farms and 60 control workers from supermarkets from February to March 2012. A walk-through survey was also performed on the 3 flower farms. Interviewed flower farm workers have high prevalences of respiratory and dermal symptoms, which are rarely reported among controls. Female workers inside the greenhouses on the 3 flower farms have significantly more respiratory and dermal symptoms than workers outside the greenhouse, also when adjusting for age and education. Limited access to personal protection equipment (PPE) and unsafe pesticide routines are documented. This study indicates that working in these flower greenhouses might be associated with adverse health effects.

Abstract
Chemical leukoderma is a skin depigmentation disorder known to occur in manufactural workplace through contact with chemicals, such as monobenzyl ether of hydroquinone (MBEH) and 4-tert- butylphenol (4-TBP). In the skin depigmented -legions induced by these chemicals, the number of melanocyte was severely decreased. Anti-melanoma agent 4-cysteaminylphenol (4-SCAP) and its derivatives are also known to cause leukoderma. Evidence has accumulated supporting that typical class of chemicals causing leukoderma is "4-alkyl/aryl-substituted phenols/catechols", which are structurally similar to melanin precursor tyrosine. Tyrosinase-mediated oxidation of these chemicals yields toxic ortho-quinones which bind to cellular proteins and produce reactive oxygen species. Accordingly, this tyrosinase-dependent metabolic activation is thought to cause melanocyte-specific damage and subsequent immune reactions toward melanocytes. Recently, rhododendrol, an inhibitor of tyrosinase developed for so-called lightening/whitening cosmetics, was shown to cause leukoderma in the users. In this review, I document the causes of known chemical leukoderma and rhododendrol- induced leukoderma, focusing on their common mechanisms underlying melanocyte loss.

Abstract
INTRODUCTION To describe the type and frequency of cutaneous manifestations of leukemia. METHODS Observational, descriptive study. We included patients over 16 years of age, with confirmed diagnosis of leukemia from the Hematology and Dermatology Departments of the outpatient clinic and from in-patients. Patients with bone marrow transplantation were excluded. A complete history and physical examination of the skin and appendages was performed, with biopsy and cultures if required. The cutaneous manifestations were classified as infection or drug-related, leukemic infiltration, associated dermatosis to leukemia and non-specific lesions. Descriptive statistics was employed. RESULTS We included 142 patients (62 females, 80 males) with the following diagnoses: acute myeloid leukemia (n=36), acute lymphoblastic leukemia (n=52), chronic myeloid leukemia (n=21), chronic lymphocitic leukemia (n=30) and hairy cells leukemia (n=3). 42% of patients (n=60) presented some dermatoses. There were 36 non-specific dermatoses, 21 drug-related, 20 infectious, 3 infiltrative and none associated. CONCLUSIONS Cutaneous manifestations directly related to leukemia are frequent, being the non-specific ones, the most commonly observed. However, a thorough dermatologic examination is important in these patients as part of an overall evaluation.

Abstract
A case of D-penicillamine(DPA) induced elastosis perforans serpiginosa(EPS) in a 32-year-old Chinese man was reported. The presentation lasted two years and was refractory to traditional medical treatment. He was then commenced on 7.6% 5-aminolevulinic acid (ALA) induced photodynamic therapy(PDT) by a LED light of 633 nm at dose levels of 130J/ cm2 for each session with total 3 sessions at one week interval. The patient was tolerated and responded well to this new approach for DPA-induced EPS without any adverse events. The etiology, pathophysiology, natural history, and treatment options for DPA-induced EPS are reviewed, and the authors suggest this method of treatment to be effective and safe for patients of DPA-induced EPS refractory to conventional therapy.

Abstract
AIM To describe spontaneous, or interferon (IFN)- or immunization-induced skin lesions in hepatitis B virus (HBV) infection. METHODS A comprehensive literature search of all the papers presenting case reports of dermatological lesions in patients with chronic HBV infection was carried out. We included only patients with histologically proven skin lesions that appeared in the normal course of hepatitis B infection, or after immunization for hepatitis B or antiviral treatment. RESULTS We found 44 papers on this topic, reporting 151 cases. About 2% of patients with hepatitis B infection, mainly men, presented with skin lesions. Among patients with chronic hepatitis B, vasculitis and essential mixed cryoglobulinemia seemed to be the most frequent skin lesion (53.3%), followed by papular changes, rashes and Gianotti-Crosti syndrome, skin carcinoma and Henoch-Schönlein purpura were rare. IFN treatment seemed to be effective against HBV-associated and immunoglobulin-complex-mediated disease (vasculitis). Two cutaneous lesions (lichen planus and granuloma annulare) were described after hepatitis B vaccination. Systemic lupus and lupus-like lesions were the most frequently encountered lesions after antiviral treatment. Immunosuppressive and steroid therapy ameliorates lichen planus lesions in 50% of cases. CONCLUSION Vasculitis was the most frequent spontaneous skin lesion found in chronic hepatitis B. Lichen planus was most frequent after immunization and lupus/lupus-like lesions after IFN.

Abstract
Arsenic contamination of groundwater in different parts of the world is an outcome of natural and/or anthropogenic sources, leading to adverse effects on human health and ecosystem. Millions of people from different countries are heavily dependent on groundwater containing elevated level of As for drinking purposes. As contamination of groundwater, poses a serious risk to human health. Excessive and prolonged exposure of inorganic As with drinking water is causing arsenicosis, a deteriorating and disabling disease characterized by skin lesions and pigmentation of the skin, patches on palm of the hands and soles of the feet. Arsenic poisoning culminates into potentially fatal diseases like skin and internal cancers. This paper reviews sources, speciation, and mobility of As and global overview of groundwater As contamination. The paper also critically reviews the As led human health risks, its uptake, metabolism, and toxicity mechanisms. The paper provides an overview of the state-of-the-art knowledge on the alternative As free drinking water and various technologies (oxidation, coagulation flocculation, adsorption, and microbial) for mitigation of the problem of As contamination of groundwater.

Abstract
OBJECTIVES Folate receptor β (FRβ)-expressing macrophages have been identified as activated macrophages. Here, we investigated the infiltration of FRβ-expressing macrophages in a murine model of bleomycin (BLM)-induced skin fibrosis and assessed the antifibrotic effects of depletion of FRβ-expressing macrophages in this model using a recombinant immunotoxin to FRβ. METHODS A recombinant immunotoxin (anti-FRβ-PE38) was prepared by conjugating the Fv portion of the anti-mouse FRβ heavy chain with truncated Pseudomonas exotoxin A (VH-PE38) and the Fv portion of the anti-mouse FRβ light chain. BLM-induced skin fibrosis mice were intravenously treated with either anti-FRβ-PE38 or VH-PE38 as a control protein. Skin fibrosis was evaluated by the change of skin thickness and hydroxyproline content on Day 29. The TGFβ1 mRNA levels in the treated skin were assessed by quantitative real-time RT-PCR on Day 9. RESULTS Numbers of FRβ-expressing macrophages increased in BLM-injected skin. Anti-FRβ-PE38 treatment led to a dramatic reduction in the number of FRβ-expressing macrophages. Additionally, skin thickness and hydroxyproline content, were markedly reduced. TGFβ1 mRNA levels were also down-regulated after the treatment. TGFβ1 expression was enriched in FRβ-expressing macrophages compared with FRβ-negative macrophages. CONCLUSION These results indicated that anti-FRβ-PE38 treatment efficiently depleted FRβ-expressing macrophages and consequently alleviated BLM-induced skin fibrosis.

Abstract
BACKGROUND Treatment options for patients with advanced or metastatic medullary thyroid cancer (MTC) have, in recent years, expanded with the approval of two tyrosine kinase inhibitors (TKIs): vandetanib and cabozantinib. Other agents, including TKIs, are under clinical investigation for MTC. Although patients treated with TKIs are at risk of developing dermatologic adverse events (AE), these untoward events may be mitigated through AE-driven algorithms. SUMMARY AE-driven algorithms combine effective nonpharmaceutical and pharmaceutical treatment modalities implemented by a multidisciplinary effort that incorporates nursing interventions, patient education, and referrals to pain-management specialists, podiatrists, and dermatologists, as appropriate. Effective AE prevention and management reduce the need for dose interruptions and modifications, allowing patients the opportunity to derive the maximal benefit from TKI therapy, while maintaining quality of life. CONCLUSIONS Optimal use of targeted therapies in the treatment of MTC depends on careful patient selection, interdisciplinary communication, and patient education and encouragement to enhance compliance and safety, optimize consistent dosing, and maximize the use of effective therapies.

Abstract
BACKGROUND Canine cutaneous T-cell lymphoma (CTCL) is an uncommon disease for which efficacious therapies are lacking. The novel anticancer nucleotide prodrug VDC-1101 (formerly known as GS-9219) has shown efficacy in dogs with multicentric lymphoma. One of the observed adverse effects with this drug was a skin change characterized by hair loss, erythema, and pruritus, implying delivery of VDC-1101 to the skin. HYPOTHESIS/OBJECTIVES The primary study objective was to identify the objective response rate (ORR) to VDC-1101 in canine CTCL; secondary objectives included characterization of progression-free survival (PFS) and adverse events (AEs). ANIMALS Twelve dogs with chemotherapy-naïve or relapsed, histologically and immunohistochemically confirmed CTCL. METHODS Dogs received VDC-1101 as a 30-minute IV infusion once every 21 days. Prednisone (1 mg/kg PO q48h) was administered concurrently. RESULTS In 11 evaluable patients, responses included 1 complete response (CR), 4 partial responses (PR), 2 stable disease (SD), and 4 progressive disease for an ORR of 45% and biologic response rate (CR/PR/SD) of 64%. The median PFS was 37.5 days (26 to >399 days), which includes 1 durable and ongoing CR (>1 year). Gastrointestinal and hematologic AEs were mild; no dogs developed grade 3 or 4 AEs. Three dogs developed dermatopathies and 1 of these dogs was removed from the study as a result of this AE. CONCLUSIONS AND CLINICAL IMPORTANCE VDC-1101 has activity against canine CTCL and could provide another treatment option in a disease process with a poor prognosis.

Abstract
We present a case of a 60-year-old woman who, after using a blemish cream purchased at a health store, presented to our clinic with a large eschar on the right neck. The active ingredient in this cream was found to be Sanguinaria canadensis, a known escharotic. This substance is popularly marketed as a natural remedy for a host of skin diseases such as blemishes, moles, warts, skin tags, basal cell carcinomas, squamous cell carcinomas, actinic keratoses, and even melanoma. The patient was treated with topical corticosteroids but is still left with a scar from the healed eschar. Dermatologists must be aware of the increasing popularity of "natural" medicinal skin cancer therapies, such as bloodroot-containing "cancer salves" and "herbal cures," and emphasize to their patients that conventional excision, micrographic surgery, electrodessication, and/or curettage are highly successful treatments for most skin cancers with little morbidity.

Abstract
BACKGROUND Determining the safety of contrast agents is challenging. In the absence of large controlled clinical trials, non-interventional (post-marketing surveillance) studies provide an opportunity to clearly investigate the safety profile of contrast agents. PURPOSE To assess the safety profile of iopromide in contrast-enhanced X-ray in clinical practice, using pooled data from three non-interventional studies. MATERIAL AND METHODS All studies were international, multicenter, non-interventional studies examining iopromide tolerability in clinical practice. Patients received iopromide (iodine concentrations of 300 mg/mL or 370 mg/mL) via intravenous or intra-arterial administration according to the diagnostic indication and in compliance with the local package insert. RESULTS In total, 132,012 patients (37 countries, >1600 centers) were included. Overall, 3823 patients (2.49%) reported an adverse drug reaction (ADR) and 1983 patients (1.50%) reported an ADR without tolerance indicators (injection site warmth, feeling hot or injection site pain, of mild intensity only). This is a similar rate to other low osmolar contrast media. In most patients, ADRs were mild (n = 2632; 1.99% of all patients) and did not require any action (n = 2799; 2.12% of all patients). ADRs were more common among women (n = 1680 [2.8%]) than men (n = 1586 [2.2%]) and among younger patients (<18 years: n = 98 [3.2%]) than older patients (18-49 years: n = 1261 [3.5%]; 50-69 years: n = 1224 [2.2%]; ≥70 years: n = 362 [1.5%]). The most common ADRs were injection site warmth/feeling hot, nausea/vomiting, and dysguesia. Forty-five serious ADRs were reported in 19 patients. ADRs were more common in at-risk patients (5.00%) than in the overall population. CONCLUSION This pooled analysis confirms the well-established good safety profile of iopromide in clinical practice in Asian and European countries and the USA.

Abstract
A lower arsenic methylation capacity is believed to be associated with various arsenic-related diseases. However, the synergistic effect of the arsenic methylation capacity and potential modifiers on arsenicosis risk is unclear. The current study evaluated the joint effect of the arsenic methylation capacity with several risk factors on the risk of arsenicosis characterized by skin lesions. In total, 302 adults (79 arsenicosis and 223 non-arsenicosis) residing in an endemic arsenism area in Huhhot Basin were included. Urinary levels of inorganic arsenic (iAs), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA) were determined, and the percentages of arsenic species (iAs%, MMA%, and DMA%), as well as two methylation indices (primary methylation index, PMI, and secondary methylation index, SMI), were calculated to assess the arsenic methylation capacity of individuals. The results showed that a lower methylation capacity, which is indicated by higher MMA% values and lower DMA% and SMI values, was significantly associated with arsenicosis after the adjustment for multiple confounders. The relative excess risk for interactions between higher MMA% values and older age was 2.35 (95% CI: -0.56, 5.27), and the relative excess risk for interactions between higher MMA% values and lower BMI was 1.08 (95% CI: -1.20, 3.36). The data also indicated a suggestive synergistic effect of a lower arsenic methylation capacity (lower DMA% and SMI) with older age, lower BMI, and male gender. The findings of the present study suggest that a lower arsenic methylation capacity was associated with arsenicosis and that certain risk factors may enhance the risk of arsenic-induced skin lesions.

Abstract
Studies have found an association between aberrant DNA methylation and arsenic-induced skin lesions. However, little is known about DNA methylation changes over time in people who develop arsenic-induced skin lesions. We sought to investigate epigenome-wide changes of DNA methylation in people who developed arsenic-induced skin lesions in a 10-year period. In 2009-2011, we conducted a follow-up study of 900 skin lesion cases and 900 controls and identified 10 people who developed skin lesions since a baseline survey in 2001-2003. The 10 cases ("New Cases") were matched with 10 controls who did not have skin lesions at baseline or follow-up ("Persistent Controls"). Drinking water and blood samples were collected, and skin lesion was diagnosed by the same physician at both time points. We measured DNA methylation in blood using Infinium HumanMethylation450K BeadChip, followed by quantitative validation using pyrosequencing. Two-sample t-tests were used to compare changes in percent methylation between New Cases and Persistent Controls. Six CpG (cytosine-phosphate-guanine) sites with greatest changes of DNA methylation over time among New Cases were further validated with a correlation of 93% using pyrosequencing. One of the validated CpG site (cg03333116; change of %methylation was 13.2 in New Cases versus -0.09 in Persistent Controls; P < 0.001) belonged to the RHBDF1 gene, which was previously reported to be hypermethylated in arsenic-exposed cases. We examined DNA methylation changes with the development of arsenic-induced skin lesions over time but nothing was statistically significant given the small sample size of this exploratory study and the high dimensionality of data.

Abstract
PURPOSE Skin toxicity is associated with a number of different chemotherapeutic agents used to treat acute leukemias. The term "toxic erythema of chemotherapy" (TEC) has been coined to describe a spectrum of skin findings, ranging from palmar-plantar erythrodysesthesia to erythema of major body folds, with erythroderma representing its most severe form. To clarify the types and frequencies of cutaneous reactions associated with clofarabine plus cytarabine chemotherapy and to compare these to those observed with clofarabine alone, we reviewed our institutional experience over a 5-year period. METHODS We reviewed the medical records of 49 patients who were treated with either regimen for acute leukemia. To facilitate comparison of the cutaneous toxicities, only patients treated with clofarabine 40 mg/m(2) daily for 5 days (days 1-5) with or without cytarabine 1 g/m(2) daily for 5 days (days 2-6) were included. RESULTS Ten patients were treated with clofarabine alone, and 40 patients received clofarabine plus cytarabine; one patient received both regimens. Treatment-associated skin toxicity developed 3-9 days following the initiation of chemotherapy and was more common in the group receiving the two-drug combination as compared to those receiving clofarabine alone [22/40 (55%) vs. 1/10 (10%) respectively, p = 0.014]. The majority of chemotherapy-related cutaneous side effects represented TEC. CONCLUSIONS Cutaneous toxicity was common and more frequent in the clofarabine plus cytarabine group when compared to patients treated with clofarabine alone. This finding is relevant for both clinicians and patients.

Abstract
Patients treated with ipilimumab or targeted inhibitors of the RAF-MEK-ERK pathway (vemurafenib, dabrafenib, and trametinib) for advanced cutaneous melanoma often experience drug-related skin toxicities denoted as dermatologic adverse events (DAEs). Although rarely life-threatening, DAEs may emerge dramatically and potentially compromise oncologic therapy if not managed in a timely and effective manner. Early recognition of DAEs is critical to providing optimal skin care and prompt consultation with a dermatologist should be obtained when a diagnosis is unclear. The expanding utilization of new melanoma drugs compels physicians to maintain a watchful eye for both known and novel DAEs and to adopt a low threshold to biopsy worrisome skin findings. Numerous therapeutic options are available to manage DAEs including topical and systemic agents as well as surgical and destructive modalities. Applying such methods improves overall patient care and optimizes the effectiveness of new therapies for advanced cutaneous melanoma.

Abstract
Every year more than 33,000 Danish patients are treated with traditional chemotherapy or targeted therapy against cancer. Cutaneous side effects to these therapies are common and may contribute significantly to the morbidity, but rarely to the mortality of the patients undergoing these treatments. We present the most classical types of drug rashes associated with antineoplastic therapy. Haematologists, oncologists and dermatologists should be aware of these reactions and early recognition and management is important for providing optimal care.

Abstract
BACKGROUND Chronic exposure to arsenic is associated with neoplastic, cardiovascular, endocrine, neuro-developmental disorders and can have an adverse effect on women's reproductive health outcomes. This study examined the relationship between arsenic skin lesions (a hallmark sign of chronic arsenic poisoning) and age of natural menopause (final menopausal period) in populations with high levels of arsenic exposure in Bangladesh. METHODS We compared menopausal age in two groups of women--with and without arsenic skin lesions; and presence of arsenic skin lesions was used as an indicator for chronic arsenic exposure. In a cross-sectional study, a total of 210 participants were randomly identified from two ongoing studies--participants with arsenic skin lesions were identified from an ongoing clinical trial and participants with no arsenic skin lesions were identified from an ongoing cohort study. Mean age of menopause between these two groups were calculated and compared. Multivariable linear regression was used to estimate the relationship between the status of the arsenic skin lesions and age of natural menopause in women. RESULTS Women with arsenic skin lesions were 1.5 years younger (p <0.001) at the time of menopause compared to those without arsenic skin lesions. After adjusting with contraceptive use, body mass index, urinary arsenic level and family history of premature menopause, the difference between the groups' age at menopause was 2.1 years earlier (p <0.001) for respondents with arsenic skin lesions. CONCLUSIONS The study showed a statistically significant association between chronic exposure to arsenic and age at menopause. Heavily exposed women experienced menopause two years earlier than those with lower or no exposure.
