CD122 was expressed at only marginal levels by both induced and natural CD8+Foxp3+ T cells (Fig. 4C), consistent with the finding that CD8+CD122+ Tregs lack Foxp3 expression 8. In contrast, all T-cell populations were predominantly CD28+ (Fig. 4C). IL-6 was recently suggested to positively regulate the expansion of CD8+Foxp3+

T cells in vitro and in vivo 17. We, therefore, compared IL-6Rα (CD126) expression among the different subsets to judge their potential sensitivity towards IL-6. Interestingly, CD126 expression was absent from both induced CD8+Foxp3+ and CD8+Foxp3− T-cell populations, whereas CD126 3 MA expression was noted on all T-cell populations ex vivo (Fig. 4C). Notably, naturally occurring CD8+Foxp3+ T cells expressed a CD8-αβ heterodimer, TCR-αβ, CD3-ε (data not shown) and partially CD4 (Supporting Information Fig. 4); the latter consistent

with previous reports 2, 25. In summary, CD8+Foxp3+ T cells express classical CD4+Foxp3+ Treg markers in a pattern distinct from activated CD8+Foxp3− T cells and previously described CD8+ Tregs. Since Foxp3 is expressed by certain effector T-cell populations in humans 26 and IFN-γ is an important effector molecule of CD8+ T cells, we next asked whether CD8+Foxp3+ and CD8+Foxp3− T-cell populations differ in IFN-γ expression. CD8+Foxp3+ and CD8+Foxp3− T cells were generated from Rag1−/−×OTI click here mice. Additionally, WT splenocytes were obtained and all populations were restimulated with PMA/ionomycin. Importantly, the majority (75.8%) of activated CD8+Foxp3− T cells produced IFN-γ, whereas almost no IFN-γ production (5.5%) was observed in induced CD8+Foxp3+ cells (Fig. 5A),

consistent with a previous study 27. Similarly, fewer CD8+Foxp3+ T cells produced IFN-γ in comparison to their Foxp3− counterpart ex vivo (Fig. 5A). IFN-γ production Farnesyltransferase by CD8+ T cells activated under Foxp3-inducing conditions could be partially restored when Foxp3 was mutated (Supporting Information Fig. 3D), yet Foxp3-independent mechanisms also seem to be involved in the repression of IFN-γ. Since suppressive function is a hallmark of Tregs, we finally tested induced CD8+Foxp3+ T cells in in vitro suppression assays. Suppressive activity was compared with activated CD8+Foxp3− T cells, CD4+Foxp3+ nTregs and induced CD4+Foxp3+ Tregs, all isolated based on eGFP reporter expression. Interestingly, not only CD8+GFP+ T cells but also activated CD8+GFP− T cells showed a mild suppressive effect on CD4+ (Fig. 5B) and CD8+ (Supporting Information Fig. 5) T-cell proliferation and on IFN-γ production by CD8+ T cells (Fig. 5C), which was however inferior to that of CD4+GFP+ natural and induced Tregs (Fig. 5B and C). In conclusion, CD8+Foxp3+ T cells are actively restricted in pool size and not enriched in suppressive function, although they share certain developmental and phenotypic characteristics with CD4+Foxp3+ Tregs.

These findings were in accordance with the previous experiments performed

with LMP2 and LMP7×MECL-1 gene-targeted mice. After adoptive transfer of these T cells, followed by an influenza virus infection of the recipient WT mice, neither LMP2−/− nor LMP7−/−×MECL-1−/− T cells were able to expand to the same extent as C57BL/6 WT cells 7, 10. As a possible explanation, the authors suggest rejection of donor T cells by the host immune response because of either reduced surface MHC expression by LMP7−/− T cells 11 or differences in minor histocompatibility Ag (miHAg). However, it was never thoroughly investigated whether the attenuation of immunoproteasome-deficient T cells in virus infected mice was indeed an artifact of the T-cell transfer experiment based on a host versus graft reaction or whether a so far unknown function of immunoproteasome subunits for T-cell survival or expansion could underlie this phenomenon. An independent hint that immunoproteasome Raf inhibition subunits

may play a so far unappreciated role for T-cell differentiation and/or expansion were the 20–30% reduced number of CD8+ as compared with CD4+ T cells in lymphoid organs of LMP2−/−12 and MECL-1−/−9 mice. Reconstitution experiments of irradiated WT mice with BM from WT and LMP7−/−MECL-1−/− mice showed that the lower CD8+/CD4+ ratio remained among the LMP7/MECL-1 double-deficient T cells although they were selected in the same thymus of recipient click here mice as WT cells with a normal CD8+/CD4+ ratio. This result indicated that the selective reduction of CD8+ T cells lacking LMP7 and MECL-1 was a T-cell intrinsic phenomenon not related to altered Ag presentation in the thymus 13. In this study, we show that a functional requirement for immunoproteasome subunits rather than graft rejection accounts for the loss of LMP2−/−, MECL-1−/− Florfenicol and LMP7−/− T cells in virus-infected mice and hence document a novel function of immunoproteasomes which is unrelated to their function in Ag processing. To investigate the proliferative performance of immunoproteasome-deficient T cells elicited

by an LCMV-WE infection in a WT environment, we adoptively transferred MECL-1−/−-, LMP2−/−-, LMP7−/−- or C57BL/6- T cells (all of them carrying the Thy1.2 marker) into LCMV-WE-infected Thy1.1 recipient mice. Eight days post-infection, C57BL/6-derived donor T cells proliferated to an extent of 2.55±0.03% of total lymphocytes, whereas mice that received LMP2−/− T cells comprised only 1.29±0.07% donor T cells. In mice having received MECL-1−/− T cells, we could hardly detect any donor cells on day 8 after infection (0.54±0.17% of total lymphocytes) and a similar loss of the graft was observed for mice which had received LMP7−/− T cells (0.18±0.03%) (Fig. 1A and B). To document the kinetics of donor T-cell expansion, we injected naïve MECL-1−/− or C57BL/6 control T cells into LCMV-WE-infected WT mice and analyzed the presence of donor T cells in blood on several days after transfer (Fig. 1C and D).

[17, 103-109] The timing LY2835219 purchase of surgical debridement in neutropenic patients remains, however,

unclear and to wait until patients have recovered from neutropenia may be of benefit. Surgical debridement of skin and soft tissue in secondary forms of aspergillosis is an option if patients do not respond to systemic antifungal treatment. The involvement of the skin and soft tissue in IA can arise because of formation of fistula. The insertion wound of a catheter can also be the entry site of Aspergillus and can develop a fungal eschar. Expansion of Aspergillus skin infection to subcutaneous veins, causing thrombophlebitis has been reported. Surgical resection of the skin and the affected thrombosed veins were necessary.[105] Failure Sirolimus of surgical therapy of an ulcer infected with Aspergillus spp. has been reported in 2012; the ulcer did not respond to antifungal therapy, surgical debridement and skin graft transplantation remained unsuccessful until the corticosteroid therapy of the patient was reduced (the patient was suffering from systemic lupus erythematosus). This indicates that although

surgical debridement may be a key factor in therapy, the immune status of the patient remains the most critical factor.[106] Similar results were reported in 2009 in a case report of an ulcer increasing in size over several months despite repeated surgical debridement and skin graft transplantation. Finally, a cutaneous T-cell lymphoma as the cause for immunosuppression was diagnosed and Aspergillus sp. was identified as the infectious

agent in the ulcer. Systemic antifungal therapy was initiated and the infection resolved, showing that surgical debridement alone might not lead to satisfying results.[109] Primary gut aspergillosis is probably misdiagnosed and underestimated in immunocompromised patients, owing specificity of symptoms and imaging. Clinical presentation includes diarrhoea, abdominal pain, gut haemorrhage, intestinal occlusion and perforation. Some of these clinical presentations represent a surgical indication/emergency, so that an initial laparotomy is intended, during which tissue samples for biopsy are obtained.[110] In less urgent situations endoscopy Thalidomide can be done to locate possible ulcerations, perforations or necrotic lesions secondary to angio-invasive Aspergillus embolism. Further progression of gut aspergillosis leads to secondary peritonitis. In a review by Kazan et al. [111] 21 cases of gut aspergillosis were investigated, 12 patients received surgery, 10 for both diagnostic and therapeutic purposes and two for resection of infected tissue as the diagnosis was already known before surgical intervention. Of the 12 patients who underwent surgery seven died, one of them during surgery. Another nine patients did not receive surgery, six of them died. The benefit of surgery to remove possible gut lesions should be higher in isolated forms, than in disseminated forms.

5a). In addition, the percentage and total number of switched GC B cells were also enhanced after late stage Treg-cell disruption. These data indicate that Treg cells participate in the control of GCs throughout the entire response, and not just at the induction phase. Given the observation that Treg cells participate in the control of GC reactions, it was of interest to explore the frequency and phenotype of the splenic Treg-cell population after immunization with SRBC. To monitor Treg cells, Foxp3-GFP reporter mice were used.47 As shown in Fig. 6(a), CD4+ Foxp3+ T cells are readily detected in the spleens of these mice, allowing for enumeration and phenotypic

characterization. Of interest, the proportion of Foxp3+ Treg cells within the splenic CD4+ compartment was unaltered throughout the GC response https://www.selleckchem.com/GSK-3.html (Fig. 6b), although total cellularity of the spleen increased modestly at days 8 and 12 (data not shown). As iTreg cells are probably activated to control the humoral find more response to novel antigens,

a range of surface markers were examined in an attempt to identify an activated iTreg-cell sub-set. When comparing naive with SRBC-challenged mice, no differences were found in the proportion of Treg cells expressing CD103, CD45RB, CD62L, CD178, GITR or PD-1 at any time-point (data not shown). Several reports have demonstrated the presence of Treg cells within the GCs of human and mouse secondary lymphoid tissue,44,45,60,61 indicating their ability to migrate into activated follicles.62 Accordingly, CXCR5 and CCR7 expression was examined on CD4+ Foxp3+ T cells from naive and immunized mice. As shown in Fig. 6(a), the splenic Treg-cell population consists of four sub-sets defined as CXCR5− CCR7+, CXCR5lo CCR7lo, CXCR5 CCR7− and CXCR5+ CCR7−. CXCR5− CCR7+ Treg cells would be expected to reside in T-cell zones with CXCR5lo CCR7lo Treg cells positioned at the borders of T-cell : B-cell

areas. CXCR5− CCR7− Treg cells would probably be found in red pulp tissue. Importantly, CXCR5+ CCR7− Treg cells should have the ability to migrate into B-cell follicles with the potential to control B-cell activity locally. In naive mice (day 0), the CXCR5− CCR7+, CXCR5lo CCR7lo, CXCR5− CCR7− and CXCR5+ CCR7− sub-sets composed 29%, 14%, 30% Etofibrate and 27% of the Treg-cell compartment, respectively. It is of interest that all four sub-sets exist in unimmunized mice, suggesting that Treg cells patrol all areas of the spleen under steady-state conditions. The four Treg-cell sub-sets were similarly enumerated in SRBC-immunized mice at days 8, 12 and 18 post-challenge. Figure 6(c) shows no change in the frequency of CXCR5− CCR7+ and CXCR5+ CCR7− Treg cells during the course of the response, indicating no major shift of Treg cells from the T-cell zone into activated follicles. Percentages of CXCR5lo CCR7lo and CXCR5− CCR7− Treg cells were also unchanged (data not shown).

Thus, in this study we investigated the effects of sMD-2 and sCD14 on the growth of both Gram-negative and Gram-positive bacteria. E. coli O111:B4 LPS (Sigma-Aldrich, St Louis, MO, USA) was re-purified according to Hirschfeld et al. (20). PG from Bacillus subtilis (Sigma-Aldrich) was confirmed to possess no TLR4-stimulatory activity up to 10 μg/ml. Unless otherwise noted, all other chemicals were from Wako Pure Chemical Industries (Osaka, Japan). The coding region of human MD-2 lacking its signal

sequence was amplified by PCR from pEIAV-hMD-2 as described previously (21) and subcloned into the yeast expression vector pGAPZα (Invitrogen, Carlsbad, CA, USA) with an N-terminal 6× histidine buy SB203580 tag sequence, resulting in plasmid pGAPZα-hMD-2. The coding region of human CD14 lacking its signal sequence and the sequence encoding the eight C-terminal amino acids (22) was subcloned into pGAPZα selleck chemical with an N-terminal 6× histidine tag sequence, resulting in plasmid pGAPZα-hCD14. A plasmid encoding a CD14 mutant lacking amino acids 57 to 64 was generated by PCR from pGAPZα-hCD14 using primers 5′-GACACGGTCAAGGCTCTC-3′ and 5′-CGCATCGACGCGCTTTAG-3′. The deletion was confirmed by automated DNA sequencing. Human MD-2 and CD14 in yeast were purified as previously described (7). pGAPZα-hMD-2

and pGAPZα-hCD14 were expressed in a Pichia expression system (Invitrogen) and purified with a Ni2+-column (Novagen, Madison, WI, USA) under denaturing conditions according to the manufacturer’s recommendations. E. coli DH5α (Invitrogen) and B. subtilis NBRC3134 were inoculated in LB broth and bacillus broth (10 g/l polypeptone, 2 g/l yeast extract, 1 g/l MgSO4·7H2O,

Tyrosine-protein kinase BLK pH 7.0), respectively and incubated at 37°C for 18 hr. After incubation, each culture was diluted to 2 × 105 CFU/ml for E. coli and 4 × 104 CFU/ml for B. subtilis with phenol red-free DMEM (Gibco, Eggenstein, Germany). Either sMD-2 or sCD14 (0.25–1 μg/ml each) was added to the culture, and myosin (Sigma-Aldrich; 1 μg/ml), which had been confirmed to have no effects on bacterial growth, was added as a control. These were cultured at 37°C for up to 18 hr. The number of viable cells was measured by plating cultures on either LB agar for E. coli or bacillus broth agar for B. subtilis and counting the number of colonies (CFU/ml). The viability of bacteria was also measured using the MTS assay in the CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega, Madison, WI, USA) according to the manufacturer’s recommendations. Wells in 96-well plates were coated with PG (250 pg/ml) in PBS at 37°C for 3 hr. After washing five times with PBST, the wells were blocked by incubating with 0.2% BSA (Sigma-Aldrich) in PBS at 4°C overnight. After five washes with PBST, either His-tagged sMD-2 or sCD14 was added at the indicated concentration, and the plates incubated at 37°C for 1 hr.

A software was developed to evaluate SE and SP of associated assays. Significant level was α = 0.05. The study included 28 Caucasian patients. According to Centers of Diseases and Control classification (CDC) clinical status, most responders belonged to clinical category B, while non-responders staged in clinical categories B and C, thus appearing to have a more advanced clinical disease. No changes in CDC clinical categories were observed during study. In line with data of literature and clinical practice, responders were characterized by lower median VL (P < 0.0001), by higher median %CD4 and AbsCD4 (P = 0.0017

SCH772984 cost and P = 0.0034) than non-responder subjects. No significant difference was observed in %CD8 and AbsCD8. A lower median CD38 ABC (P = 0.0004) and a lower median %CD38/CD8 (P = 0.0049) were detected in responders as compared to non- responders. CD38 ABC and %CD38/CD8 showed a good correlation (rs = 0.89, P < 0.0001) and a very high concordance (Cohen K = 0.83). The study of T cell responses showed a higher fraction of a good LPR in responders as compared to non-responders, but the difference was not statistically significant (Table 1). RXDX-106 nmr Assuming that patients were correctly classified into responder and non-responder groups by standard criteria, based on

VL and CD4 cells, we compared the ability of CD38 expression on CD8 T cell to differentiate Thiamet G responders versus non-responders in a single point measurement after a minimum of 6 months of therapy. Both CD38 ABC and %CD38/CD8 showed a good discrimination: the area under

ROC curves (AUC) was equal to 0.901 and 0.815, respectively. The difference in AUC between the two measures was not significantly different (P = 0.089). However, the shape of ROC curves suggests a trend towards an overall higher sensitivity with CD38 ABC than with %CD38/CD8 (Fig. 1). The automatically established 2401 CD38 ABC and 85%CD38/CD8 cutoff values were endowed with the best proportion of correct classifications. CD38 expression ≥2401 CD38 ABC and ≥85% CD38/CD8 resulted in 75.0% sensitivity (identification of non-responders) and 93.8% specificity (identification of a responder), when used as single assays. The association of the two different measures of CD38 expression showed that sensitivity improved to 83.3%, when it was sufficient to obtain either a value ≥2401 CD38 ABC or ≥85% CD38/CD8 to define a non-responder, while sensitivity decreased to 66.7% when the definition of a non-responder was based on having both ≥2401 CD38 ABC and ≥85% CD38/CD8. LPR data analysis showed that Poor LPR had a low sensitivity in the identification of non-responders (sensitivity 25%), while Good LPR was valuable at identifying response to therapy (specificity 81.3%).

Dissatisfaction was infrequent. Conclusion:  This pilot study suggests that older patients trained to dialyse at home using PD or HD are highly satisfied with the nephrology service – even when living remote from the nephrology unit. Home-based dialysis is possible in older patients with levels of comorbidity and disease

severity as serious as elsewhere. “

“There has been a global decline in the uptake of home-based dialysis therapies in the past 20 years. The ability to provide appropriate information to potential patients in this area may be confounded by a lack of knowledge of home dialysis options. The aim of this study was to develop a web-based education package for health professionals to

increase knowledge and positive perceptions of home-based dialysis options. A three-module e-learning package concerning home dialysis was developed under the auspices of the home dialysis

first project. These modules were tested on 88 undergraduate health professionals. Changes in attitudes and knowledge of home dialysis were measured using custom designed surveys administered electronically to students who completed the modules. Matched pre and post responses to the survey Tau-protein kinase items were compared using Wilcoxon signed rank tests. The pre survey indicated clear deficits in existing knowledge of home dialysis options. In particular, when asked if haemodialysis could be performed at home, 22% of participants responded ‘definitely no’ and a further 24% responded ‘probably no’. Upon completion of the e-learning, post survey responses indicated statistically significant improvements (P < 0.001) in eight of the nine items. When asked if the e-learning had increased their knowledge about home dialysis, 99% of participants responded ‘definitely yes’. A suite of web-based education modules can successfully deliver significant improvements in awareness and knowledge around home dialysis therapies. "
“Aim:  To evaluate their prognosis, the damage by melamine on children’s kidney and other organs, and its influence on the children’s development, was investigated.

Both IL-23 and IL-17 have been shown to impair the antifungal effector activities of mice neutrophils by counteracting the IFN-γ-dependent activation of IDO

(see below), which is known to limit the inflammatory status of neutrophils against fungi, such as A. fumigatus [53], and which likely accounts for the high inflammatory pathology and tissue destruction associated with Th17-cell activation. In its ability to inhibit Th1 activation, the Th17-dependent pathway could be responsible for the failure to resolve an infection in the face of ongoing inflammation. IL-17 selleck chemicals neutralization was shown to increase A. fumigatus clearance, ameliorate inflammatory pathology murine lungs, and restore protective Th1 antifungal resistance [54]. The complex fungal communities encompassing food-borne and environmental fungi present in the host dictate the generation of the different Th-cell NVP-LDE225 concentration subtypes as a result of exposure to different microbial adjuvants. For example, fungal β-glucan mediated dectin-1 activation on the surface of human DCs induces CD4+ Th1- and Th17-cell proliferation [55] and primes cytotoxic T cells in vivo [56]. Other fungal cell wall Ags, such as chitin, have been shown to alternatively activate macrophages to drive Th2 immunity [57]. However PRRs might be used by fungi to escape and subvert the host immune responses in order to survive and

eventually replicate, that is, the C. albicans induction of IL-10 release through TLR2 [58]. The ability to switch between yeast and hyphal growth is one of the key virulence attributes of C. albicans: this causes the blockade of TLR recognition by Ag modification during the germination of yeasts into hyphae [59]. It is clear that yeast and hyphae induce different responses [60] by exposing different cell wall Ags [61] to protective immunity. Thus, the nature of cell wall Ags likely also serves to promote a specific inflammatory phenotype. Indeed, fungal pathogenicity should be examined GPX6 in the context of features of host responses to environmental and commensal fungi and the circumstances that influence

the balance between healthy, tolerated exposure to fungi, and pathogenicity, seen as a loss of balance of the resident microbial communities and their relative abundance in different bodily sites and organs. Commensal microbes significantly shape mammalian immunity, both at the host mucosal surface and systemically [62, 63], controlling unexpected microbial burden and growth. However, it is unclear how opportunistic fungi, such as C. albicans, remain at mucosal surfaces in the face of adaptive immunity as commensals, that is, as components of the mycobiota of a healthy host. Here, the fungus is controlled by (i) the microbial flora of the healthy host, (ii) the epithelium, which is able to secrete antimicrobial peptides, and (iii) the local innate immune system. Candida spp.

It is important to avoid duplication of effort by organizations and to efficiently use the available expertise and resources. As a consequence KHA-CARI have committed to adapting selected KDIGO guidelines to meet Australian and New Zealand circumstances and requirements rather than producing separate guidelines. This summary guideline is an adaptation of the KDIGO Clinical Practice Guideline for Acute Kidney Injury.[1] The summary includes a brief description of the adaptation methodology and the adapted recommendations and

suggestions for each subtopic. The complete KHA-CARI adapted guideline can be accessed at the KHA-CARI website (http://www.cari.org.au). The ultimate purpose of the adapted guideline is to provide a comprehensive listing of recommendations relevant to Australian and New see more Zealand practice following a detailed review and update of the KDIGO guidelines. The process used for the adaptation has been based on the ADAPTE framework. The ADAPTE framework has been developed

to facilitate review of multiple guidelines for evaluation and synthesis into a single adapted guideline Z-VAD-FMK purchase for local use. In this case the adaptation is of a single guideline only. As a consequence KHA-CARI has used the following simplified approach: Step 1: Assess guideline currency Step 2: Assess guideline consistency Step 3: Assess applicability of the recommendations with respect to Australia and New Zealand Step 4: Prepare an adapted guideline document with recommendations Vildagliptin and suggestions reflecting assessments made in Steps 1 to 3 The KDIGO Clinical Practice Guideline for Acute Kidney Injury (AKI) was published in March 2012 and contained five sections on the topics ‘Introduction and Methodology’, ‘AKI Definition’, ‘Prevention and Treatment of AKI’, ‘Contrast-induced AKI’ and ‘Dialysis Interventions for Treatment of AKI’. This adapted guideline addresses issues relevant to the care of patients with acute kidney injury in Australia and New Zealand. The guideline does not address issues related to vascular access,

dialyser membranes, use of bicarbonate versus lactate as a buffer in dialysate, and criteria for stopping renal replacement therapy in AKI. The section on biomarkers has been updated and the definition of AKI has been broadened. The incidence of AKI is increasing worldwide.[2] While epidemiological data on AKI is sparse, an indication from Australian hospital separation data and peer reviewed articles suggest that the incidence of AKI is increasing. In Australia in 1998–1999 AKI accounted for 0.075% of total hospital separations and in 2009–2010 this figure increased to 0.094%.[3] In the intensive care unit (ICU) on the day of admission between 35–40% of patients admitted to ICU fulfil the RIFLE criteria for AKI.

“From

January 2000 to May 2008, 50 patients with facial contour deformities underwent soft tissue augmentation with 51 anterolateral thigh (ALT) adipofascial flaps. Fifty flaps survived with no complications; partial fat necrosis occurred in one flap. Mean follow-up was 16 months. Flaps ranged from 10 × 6 cm to 20 × 12 cm. Perforators were found in 50 flaps, 43 musculocutaneous perforators (84.3%) and 7 septocutaneous perforators (13.7%), with a mean of 2.5 perforators per flap. In one flap (2.0%), no perforator was found. In this case, we used an anteromedial thigh adipofascial flap using the medial

branch of the descending branch of lateral circumflex femoral artery as the vascular pedicle. Relatively symmetric facial contour was achieved in 20 cases. In 30 cases, adjunctive procedures including flap debulking, fat injection, and resuspension were necessary, and 23 patients achieved satisfactory outcomes. We conclude that the ALT adipofascial flap can be successfully elevated and transplanted for the correction of soft tissue facial defects. This flap can provide tissue to Astemizole fill large defects, and posses https://www.selleckchem.com/products/iwr-1-endo.html the qualities of pliability, an excellent blood supply, ease of suspension and fixation, and minimal morbidity at the donor site. © 2010 Wiley-Liss, Inc.

“The purpose of this study was to examine the current role of the iliac crest osteocutaneous flap in mandibular reconstruction, with a focus on the reliability of its skin island. We reviewed outcomes in 18 cases of immediate mandibular reconstruction with the iliac crest flap. Intraoral mucosal defects were closed with the skin island of the iliac crest flap in 13 patients (iliac crest flap group) and were closed with another free flap, because of poor circulation of the iliac crest skin island, in five patients (double-flap group). Postoperative results were poor in the iliac crest flap group. The rate of partial or total loss of the skin island was 46.2% in the iliac crest flap group and 20.0% in the double-flap group. The presence of a dominant perforator did not reduce the overall rate of recipient-site complications or reoperation. Combined use of another skin flap for intraoral lining provided better results. These results suggest that the skin island of the iliac crest flap should not be used for intraoral lining, unless adequate circulation of the skin island can be confirmed.
