Abstract
Vitiligo is a common acquired disease of pigment loss. In lesions recalcitrant to non-invasive treatment, transplantation of cultured autologous melanocytes is an emerging choice. Conventionally, the recipient site is often prepared by laser-mediated or mechanical dermabrasion. Such preparation procedures have disadvantages including prolonged transplantation duration, long period for reepithelialization and potential scarring. We propose a method of preparing recipient sites by psoralen and controlled ultraviolet A (PUVA)-induced blistering followed by transplanting suspended melanocytes. We introduced this method in 10 patients with segmental vitiligo on their recipient site 3 to 5 days before transplantation and blistering developed in 2 to 3 days afterwards. On the day of transplantation, the blister roof could be peeled off easily without bleeding and the recipient site preparation could be completed in 20 min. The recipient site became reepithelialized within 1 week. Progressive repigmentation was observed for up to 6 months, with an average of 65.06% repigmentation in the recipient site without scarring at the end of follow-up. Hence, preparation of the recipient site by controlled PUVA-induced sunburn-like blistering can potentially facilitate melanocyte transplantation and prevent scarring.

Abstract
Background Uremic pruritus is a common and frustrating symptom among patients receiving peritoneal dialysis (PD). This study aimed to examine the prognostic importance of uremic pruritus and to identify the determinants for higher pruritus intensity in PD patients. Methods We conducted a prospective cohort study of patients receiving maintenance PD. A visual analogue scale (VAS) score was used to measure the intensity of uremic pruritus. The composite endpoint of PD technique failure or all-cause death was assessed using a multivariable Cox proportional hazards model. The determinants for the VAS score of uremic pruritus was assessed using a multivariable linear regression model. Results Among the 85 PD patients, 24 (28%) had uremic pruritus. During a median follow-up of 28.0 months, 12 patients experienced technique failure, and 7 died. We found that a higher VAS score of pruritus intensity was an independent risk factor for technique failure or death (hazard ratio, 1.64; 95% confidence interval, 1.18 to 2.28; P = 0.003) after adjusting for a variety of confounding factors. We also found that a weekly total Kt/V of less than 1.88, a longer duration of dialysis, a higher dietary protein intake, and higher blood levels of intact parathyroid hormone and high-sensitivity C-reactive protein were independent determinants of higher VAS scores of pruritus intensity. Conclusions Our results show that uremic pruritus is an independent risk factor of technique failure and death in patients receiving PD. We also found that a weekly total Kt/V < 1.88 is associated with higher intensity of uremic pruritus in PD patients.

Abstract
Uremic pruritus is common and bothersome in patients receiving either peritoneal dialysis (PD) or hemodialysis (HD). To date, the preferred dialysis modality regarding the alleviation of uremic pruritus remains controversial. We conducted this cross-sectional study to compare the prevalence, intensity, and characteristics of uremic pruritus between PD and HD patients. Patients receiving maintenance dialysis at a referral medical center in Taiwan were recruited. Dialysis modality, patient demographic, clinical characteristics, and laboratory data were recorded. The intensity of uremic pruritus was measured using visual analogue scale (VAS) scores. Multivariate linear regression analysis was conducted to compare the severity of uremic pruritus between PD and HD patients. Generalized additive models were applied to detect nonlinear effects between pruritus intensity and continuous covariates. A total of 380 patients completed this study, with a mean age of 60.3 years and 49.2% being female. Uremic pruritus was presented in 24 (28.6%) of the 84 PD patients and 113 (38.2%) of the 296 HD patients (P = .12). The VAS score of pruritus intensity was significantly lower among the PD patients than the HD patients (1.32 ± 2.46 vs 2.26 ± 3.30, P = .04). Multivariate linear regression analysis showed that PD was an independent predictor for lower VAS scores of pruritus intensity compared with HD (β-value -0.88, 95% confidence interval -1.62 to -0.13). The use of active vitamin D was also an independent predictor for a lower intensity of uremic pruritus, whereas hyperphosphatemia and higher serum levels of triglyceride and aspartate transaminase were significantly associated with higher pruritus intensity. There was a trend toward a less affected body surface area of uremic pruritus in the PD patients than in the HD patients, but the difference did not reach statistical significance (P = .13).In conclusion, the severity of uremic pruritus was lower among PD patients than HD patients, and PD may provide better alleviation of pruritus symptoms. The result provides a valuable reference for clinicians and patients when choosing a dialysis modality.

Abstract
Insulin-like growth factor-II mRNA-binding protein 3 (IMP-3) is an RNA-binding protein expressed in multiple cancers, including melanomas. However, the expression of IMP-3 has not been investigated in acral lentiginous melanoma (ALM). This study sought to elucidate its prognostic value in ALMs. IMP-3 expression was studied in 93 patients diagnosed with ALM via immunohistochemistry. Univariate and multivariate analyses for survival were performed, according to clinical and histologic parameters, using the Cox proportional hazard model. Survival curves were graphed using the Kaplan-Meier method. IMP-3 was over-expressed in 70 out of 93 tumors (75.3%). IMP-3 expression correlated with thick and high-stage tumor and predicted poorer overall, melanoma-specific, recurrence-free and distant metastasis-free survivals (P = 0.002, 0.006, 0.008 and 0.012, respectively). Further analysis showed that patients with tumor thickness ≤ 4.0 mm and positive IMP-3 expression had a significantly worse melanoma-specific survival than those without IMP-3 expression (P = 0.048). IMP-3 (hazard ratio 3.67, 95% confidence intervals 1.35-9.97, P = 0.011) was confirmed to be an independent prognostic factor for melanoma-specific survival in multivariate survival analysis. Positive IMP-3 expression was an important prognostic factor for ALMs.

Abstract
IGF II mRNA-binding protein 3 (IMP-3) has been reported to be a marker of melanoma progression. However, the mechanisms by which it impacts melanoma are incompletely understood. In this study, we investigate the clinical significance of IMP-3 in melanoma progression and also its underlying mechanisms. We found that IMP-3 expression was much higher in advanced-stage/metastatic melanomas and that it was associated with a poor prognosis (P=0.001). Univariate analysis showed that IMP-3 expression was associated with stage III/IV melanomas (odds ratio=5.40, P=0.031) and the acral lentiginous subtype (odds ratio=3.93, P=0.0034). MeWo cells with overexpression of IMP-3 showed enhanced proliferation and migration and significantly increased tumorigenesis and metastatic ability in nude mice. We further demonstrated that IMP-3 could bind and enhance the stability of the mRNA of high mobility group AT-hook 2 (HMGA2). It was also confirmed that IMP-3 had an important role in melanoma invasion and metastasis through regulating HMGA2 mRNA expression. IMP-3 expression was positively correlated with HMGA2 expression in melanoma cells and also in melanoma tissues. Our results show that IMP-3 expression is a strong prognostic factor for melanoma, especially acral lentiginous melanoma.

Abstract
A murine repeated protein-patch model has been established to study epicutaneous sensitization in atopic dermatitis. This model has shown a predominant Th2 and a weak Th1 response in both BALB/c and C57BL/6 mice. However, Th responses induced in the repeated model are not consistent with the generally accepted theory that BALB/c and C57BL/6 mice are Th2 and Th1 prone and are representatives of human atopy and non-atopy, respectively. In this study, a single protein-patch model was established, which showed in addition to the Th2 response, a remarkable Th1 response in C57BL/6 mice, but not in BALB/c mice. Moreover, using muLangerin-DTR mice, we demonstrated that dermal dendritic cells, but not Langerhans cells, are critical in single epicutaneous sensitization in both strains of mice.

Abstract
BACKGROUND Higher CXCR4 expression enhances basal cell carcinoma (BCC) invasion and angiogenesis. The underlying mechanism of increased CXCR4 expression in invasive BCC is still not well understood. OBJECTIVE To investigate the mechanisms involved in the regulation of CXCR4 expression in invasive BCC. METHODS We used qRT-PCR, RT-PCR, Western blot, and flow cytometric analyses to examine different CXCR4 levels among the clinical samples, co-cultured BCC cells and BCC cells treated with recombinant transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF). Immunohistochemical studies were used to demonstrate the correlation between TGF-β1 and CXCR4 expressions. The signal transduction pathway and transcriptional regulation were confirmed by treatments with chemical inhibitors, neutralizing antibodies, or short interfering RNAs, as well as luciferase reporter activity. RESULTS Invasive BCC has higher TGF-β1 and CTGF levels compared to non-invasive BCC. Non-contact dermal fibroblasts co-culture with human BCC cells also increases the expression of CXCR4 in BCC cells. Treatment with recombinant human TGF-β1, but not CTGF, enhanced the CXCR4 levels in time- and dose-dependent manners. The protein level and surface expression of CXCR4 in human BCC cells was increased by TGF-β1 treatment. TGF-β1 was intensely expressed in the surrounding fibroblasts of invasive BCC and was positively correlated with the CXCR4 expression of BCC cells. The transcriptional regulation of CXCR4 by TGF-β1 is mediated by its binding to the TGF-β receptor II and phosphorylation of the extracellular signal-related kinase 1/2 (ERK1/2)-ETS-1 pathway. CONCLUSION TGF-β1 induces upregulation of CXCR4 in human BCC cells by phosphorylation of ERK1/2-ETS-1 pathway.

Abstract
OBJECTIVE To investigate the clinical and pathologic features of patients with drug reaction with eosinophilia and systemic symptoms (DRESS) in Taiwan. DESIGN Case series and retrospective analysis. SETTING A medical referral center in Northern Taiwan. PATIENTS Sixty cases of DRESS occurring from June 1998 to May 2008. MAIN OUTCOME MEASURES Clinical characteristics for specific drugs and important prognostic factors in DRESS. RESULTS Patients ranged in age from 6 to 90 years (mean age, 51 years). The female to male ratio was 1.3 to 1. The most common culprit drugs were allopurinol, phenytoin, and dapsone. Exanthematous eruption was the most common skin manifestation, but purpurae and blisters were also observed. Hepatic (80%), renal (40%), and pulmonary (33%) involvement were also common. The overall mortality rate was 10%. Allopurinol-induced DRESS was characterized by preceding chronic renal insufficiency and frequent renal involvement. Pancytopenia indicated a poor prognosis. CONCLUSIONS Drug reaction with eosinophilia and systemic symptoms has a variable clinical presentation, and its definition requires clarification. It may be a heterogeneous syndrome with some particular patterns related to different drugs. Early diagnosis and prompt discontinuation of offending drug regimens are essential.

Abstract
Generally, cells tend to aggregate on a substratum with lower cell adhesivity. However, it also leads to compromised cell growth and higher cell loss after seeding. This study is aimed at tackling this dilemma by extracellular matrix (ECM) protein coating of a lower adhesive substratum poly(ethylene-co-vinyl alcohol) (EVAL) that has been shown to facilitate hair follicle dermal papilla (DP) spheroid formation. We found that coating with either fibronectin (Fn), collagen I, or collagen IV yields higher adhesivity and cell growth than that with laminin. However, cells can only aggregate on uncoated or Fn-coated EVAL. Quantitatively, Fn coating increases the number of spheroids by 67%. Analysis of cell migration reveals that collagen I, collagen IV and laminin coatings reduce cell motility, while Fn coating keeps cells highly motile. Inhibition of cell migration hinders spheroid formation. In addition, disruption of Fn function does not significantly compromise intercellular adhesion. Hence, Fn enhances cell aggregation by enhancing cell attachment, cell growth and cell motility. Our study demonstrates that intercellular organization as spheroids or flat monolayers is switchable by specific ECM protein coating and preserving cell motility is vital to cell aggregation. In addition to generation of spheroidal DP microtissues for hair follicle regeneration and large-scale production of aggregates of other cells, this strategy can help to regulate the tissue-substrate adhesivity and tissue spreadability on the surface of implantable materials.

Abstract
BACKGROUND Th17 is a newly identified effector T cell lineage which plays a central role in many human inflammatory diseases and experimental animal models. Epicutaneous sensitization with a protein antigen has been proven to induce a Th2-predominant immune response and lead to development of atopic diseases in a murine protein-patch model. OBJECTIVE We sought to assess the generation of Th17 cells in epicutaneous sensitization with a protein antigen and its regulation by environmental elements and genetic background. METHODS BALB/c, C57BL/6, and DO11.10 mice were epicutaneously immunized by patch application of the following: ovalbumin alone, or co-administration of one of TLR ligands, irritant, hapten or superantigens. IL-17 and IL-22 contents in supernatants of in vitro reactivation culture of lymph nodes cells were determined by ELISA. Frequency of IL-17-secreting CD4 T cells was measured by ELISPOT. RESULTS Small but significant amounts of IL-17 and IL-22 could be detected in supernatants of in vitro reactivation culture of lymph nodes cells of mice receiving patch application of ovalbumin. ELISPOT assay for IL-17 also revealed low frequency of IL-17-secreting CD4 T cells in lymph nodes cells in ovalbumin group. All TLR ligands tested including agonists for TLR2, TLR3, TLR4, TLR5, TLR7 and TLR9 as well as many environmental elements including irritant, hapten and superantigen could further promote the generation of Th17 cells. In addition, C57BL/6 mice generate less Th17 cells than BALB/c mice in epicutaneous sensitization. CONCLUSION This study demonstrates Th17 generation and its regulation by environmental elements and genetic background to a protein antigen by epicutaneous route.

Abstract
Epicutaneous sensitization has been an important route for protein allergen sensitization in atopic disease. Although the skin is irradiated by sunlight daily, the influence of visible light on epicutaneous sensitization has not been explored. In this study, by using a well-established murine protein-patch model, we show that low-energy visible light (LEVL) irradiation could differentially modulate the predominant Th2 immune response induced by epicutaneous sensitization with protein antigen. When the induced Th2 response was strong, as usually observed in BALB/c mice, LEVL irradiation suppressed the response. In contrast, LEVL irradiation enhanced the weaker Th2 response in C57BL/6 mice. Increased IL-18 and decreased TGF-beta expression in draining lymph nodes after LEVL irradiation was observed in BALB/c mice, but not in C57BL/6 mice. LEVL irradiation also enhanced IL-18 expression in skin and reduced the downregulation of CD24 expression on epidermal Langerhans cells in draining lymph nodes of BALB/c mice. Collectively, these results provide evidence for immunomodulatory effects of LEVL irradiation and will help us develop a useful strategy for prevention of allergen sensitization.

Abstract
Paraneoplastic pemphigus (PNP), also called paraneoplastic autoimmune multiorgan syndrome, is a rare disorder associated with underlying neoplasia. The common underlying neoplasms include non-Hodgkins lymphoma, chronic lymphocytic leukemia, and Castlemans disease. Though B-cell lymphoma is the most common underlying malignancy, only one case associated with splenic B-cell lymphoma has been recognized. The prognosis of PNP is very poor, and PNP-associated bronchiolitis obliterans (BO) is not uncommon. Herein, we report a 44-year-old woman who initially presented with multiple oral ulcers, conjunctivitis, and numerous cutaneous blisters. Serial workup established the diagnosis of PNP and revealed an underlying splenic B-cell lymphoma. Although the mucocutaneous lesions gradually healed after splenectomy and chemotherapy, deteriorating respiratory function developed 7 months later with pathologically proven BO. She finally succumbed to respiratory failure 12 months after presentation despite intensive respiratory care.

Abstract
Epicutaneous sensitization with a protein antigen was demonstrated to induce a predominant type 2 CD4 T cell response with high IgE production in mice. On the other hand, its CD8 T cell responses have not been addressed probably partly because of the generally accepted concept that cross-priming of soluble protein is an inefficient process. Here, we used an established patch-applied murine model to demonstrate that cross-priming with an epicutaneously introduced soluble protein antigen, though inefficient, generated mainly Tc1 cells, but not Tc2 cells. In the presence of an irritant or hapten, the efficiency of this cross-priming process could be enhanced and more Tc1 cells were generated. CpG oligonucleotides also promote the generation of Tc1 cells. In contrast, lipopolysaccharide and poly (inosinic-cytidylic) acid [poly (I:C)] have no effect. Together, these results provide supportive evidence of the epicutaneous sensitization of human cutaneous lymphocyte-associated antigen-positive CD8 T cells found in the peripheral blood or tissues of patients. The surprising observation of the type 1 character of the generated CD8 T cells will also help us to better understand the complicated pathogenesis of atopic and cutaneous inflammatory diseases.

Abstract
SETTING A medical centre in Taipei, Taiwan. OBJECTIVE To investigate the trend and characteristics of patients with non-tuberculous mycobacteria (NTM) related skin and soft tissue infection. DESIGN A total of 63 patients with culture-proven diseases were identified from January 1997 to December 2004. The medical records of all patients were reviewed. RESULTS Twenty-seven patients were infected with rapidly growing mycobacteria (RGM), 19 with Mycobacterium marinum, six with M. avium complex (MAC), five with M. kansasii and six with other species. Most patients presented with a protracted cutaneous lesion without systemic symptoms, and two thirds of the patients had a history of exposure. Seventy-three per cent of the lesions involved the extremities. Underlying illness with suppressed immunity was documented in 30.2% of the patients, and was most prevalent in patients with MAC (100%) and M. kansasii (60%). Of the patients, 62% underwent at least one surgical intervention, and 77.8% received treatment with different antimicrobial combinations. Most patients (86%) recovered completely. Granulomatous inflammation was found in 88.9% of biopsied tissue associated with M. marinum infection, 31.8% with RGM and 25.0% with MAC. CONCLUSION A combination of surgery and antimicrobials cured most patients with microbiologically proven localised NTM skin and soft tissue infection.

Abstract
Atopic dermatitis (AD) is a complex disease with both a genetic background and environmental interactions. Although multiple linkage-analyses about AD have been studied, there have been only a few family aggregation tests of AD or perennial allergic rhinitis (AR) to date. The association of allergen-specific IgE in AD and atopic dermatitis with allergic perennial rhinitis (ADR) have also been seldom discussed. The purpose of this study was to evaluate family aggregation and assess allergen-specific IgE in patients with AD and ADR. We also planned to investigate the effect of family history of AD on the prevalence of allergen-specific antibodies. The serum levels of IgE, eosinophil cationic protein (ECP) and major basic protein (MBP) were measured and compared in patients with AD and those with ADR. Proportional analysis compared allergen-specific IgE between AD and ADR. The family aggregation was conducted to estimate the odds ratio for various atopic diseases in different family members. Total IgE and allergen-specific antibodies in serum were compared between those patients who had AD with AR and those without. The result revealed that allergic rhinitis is the most common concomitant atopic disease associated with AD. The ADR group was more likely to have serum mite-, cockroach-, and feather-specific IgE. The positive rates for wheat, peanut and soybean were higher in those AD without rhinitis. In the family aggregation of AD, the odds ratio for siblings was higher than for parents, the ratios for brother and sister were 9.91 and 8.75, respectively. However, the odds ratio for parents of ADR was higher than siblings; the ratios for father and mother of ADR were 8.22 and 2.94, respectively. AD patients with family histories of AD were more likely to have mite-, soybean-, and peanut-specific antibodies in their serum. We concluded that aeroallergens are the most important allergens aggravating atopic diseases in Taiwan. Food plays an important role in the pathogenesis of AD. Measurement of serum total IgE combined with the MAST-CLA test could be helpful in the diagnosis of atopic diseases. The differential aggregation tendency for AD and ADR implicated the complexity of the gene-environment interaction in these atopic diseases.

Abstract
We present a case of non-obstructive bladder diverticulum in a 75-year-old post-menopausal woman. An ovarian cyst was previously suspected, which resulted in a futile exploratory laparotomy without making any definite diagnosis, 1 year earlier. During this admission, transvaginal ultrasound-guided cyst aspiration was arranged to determine the nature of the presumed 'recurrent' cyst and to relieve the symptoms. Prior to cyst aspiration, up to 700 ml of urine through urinary catheterisation and the gradual disappearance of the 'cyst' alerted us to the possibility of a bladder diverticulum, which was later confirmed by retrograde cystography. This case illustrates the lessons that despite considerable researches having been done on enhancing sonographic accuracy, diagnosis based on imaging alone is likely to be associated with multiple pitfalls. Recognising the common pitfalls and integrating clinical information and alertness with ultrasonic features remains the mainstay of sonographic differential diagnosis.

Abstract
Kaposiform hemangioendothelioma and tufted angioma are viewed as two separate disease entities in the current classification of vascular tumors. However, the concurrence of features of both vascular tumors in the same specimen of some patients raises the question whether these tumors exist on a continuum. Herein, we report a dynamic transformation between both tumors within a single patient, which suggests they are two variants of the same vascular tumor.
