RESUMO

AIM: To assess the accuracy of Magnetic Resonance Index of Activity (MaRIA) in evaluating therapeutic efficacy in Crohn's disease (CD) patients with different activity levels using ileocolonoscopy as the reference standard. MATERIALS AND METHODS: Forty-eight patients underwent magnetic resonance enterography (MRE) and ileocolonoscopy at baseline, week 26, and week 52, along with the Simple Endoscopic Score for Crohn's Disease (SES-CD) and MaRIA scores. According to the SES-CD score at baseline, all patients were subdivided into mild, moderate, and severe activity subgroups. The identification of endoscopic mucosal healing (MH) was explored primarily. Moreover, the Crohn's Disease Activity Index (CDAI), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), and interleukin-6 (IL-6) levels were collected and analysed. RESULTS: MaRIA correlated significantly with SES-CD and CRP at baseline, week 26, and week 52. The discrepancies in MaRIA and SES-CD were statistically significant before and after treatment. MaRIA = 24.43 and ΔMaRIA = 12.77 as the cut-off points were found to have high diagnostic accuracy for predicting MH. MaRIA (p<0.001), SES-CD (p<0.001), CRP (p<0.05), ESR (p<0.05), and CDAI score (p<0.05) in patients with MH were considerably decreased compared to those in patients without MH. CONCLUSIONS: MRE has good application value in evaluating the therapeutic response of CD patients treated with biological agents. MaRIA is a reliable indicator in the follow-up of CD patients, which is strongly correlated with SES-CD, and it has high accuracy in predicting endoscopic MH.

RESUMO

BACKGROUND: Onychopapilloma is a benign tumour of the nail bed and distal matrix and commonly presents as longitudinal erythronychia, longitudinal leukonychia or longitudinal melanonychia. Because onychopapilloma is rare, its clinical characteristics and dermoscopic findings have not been well investigated in Asia. OBJECTIVES: This study aimed to investigate the clinical characteristics and dermoscopic and pathologic findings of onychopapilloma in Korea. METHODS: We retrospectively reviewed the medical records and clinical/dermoscopic photographs of 39 patients diagnosed with onychopapilloma in the Pusan National University Hospitals (Busan and Yangsan) for 11 years (2010-2021). RESULTS: Among 39 patients, 23 (59.0%) were men, and 16 (41.0%) were women. The mean age was 46.1 (16-77) years. All lesions were single, and most of them were located on the fingers (92.3%), especially the thumb (66.7%). The most common clinical feature was longitudinal erythronychia (56.4%), and the most common dermoscopic finding was distal subungual hyperkeratosis (100%). We found two new dermoscopic features: macrolunula and trailing lunula along the longitudinal band. Among 18 patients who underwent surgical excision, only 6 (33.3%) showed typical acanthosis and papillomatosis on the nail bed. CONCLUSIONS: We found that Asian onychopapilloma has similar clinicodermoscopic findings to the Caucasian one, that is to say, longitudinal erythronychia and distal subungual hyperkeratosis were the most common nail change and dermoscopic finding, respectively. We propose two new dermoscopic features of onychopapilloma: macrolunula and trailing lunula along the longitudinal band.

RESUMO

The Levant Basin is in many ways the world's most invaded marine ecosystem owing to the existence of the man-made Suez Canal. The invasion of free-living organisms through this pathway is increasingly documented and monitored in the past two decades, and their ecological impact recognized. Nonetheless, while tremendous scientific effort is invested in documenting introduced fishes, co-introduction events of these fishes and their parasites have drawn relatively little interest. In our research, we examined the presence of gill parasites (Monogenea) on the invasive narrow barred Spanish mackerel Scomberomorus commerson which has been known in the Mediterranean Sea for 80 years. The gills of S. commerson supported numerous, relatively large monogeneans (Monogenea: Gastrocotylinea), reaching prevalence levels of 100% with a mean intensity of ~ 80 worms per host. Using an integrated molecular and morphological approach, four gastrocotylinean species were identified: Gotocotyla acanthura, Cathucotyle cathuaui, Pricea multae, and Pseudothoracocotyla ovalis. Two species, C. cathuaui and P. ovalis, are reported here for the first time from the Mediterranean. Sequences of the 28S rRNA gene of G. acanthura from native hosts, Pomatomus saltatrix and Trachinotus ovatus, differed from individuals collected from S. commerson by 1.8%. We therefore suggest that the taxonomic status and distribution of G. acanthura should be revisited, and we recommend an integrated approach as essential to accurately detect co-introductions.

RESUMO

Background: Glucocorticoid receptor (GR) is shown to have variable frequency of expression in invasive tumors of the breast. Investigation of additional nuclear receptors like GR in receptor negative tumors like triple negative breast cancer (TNBC) may have prognostic and therapeutic significance. Methods: Expression of GR was evaluated by immunohistochemistry in 175 tumors of invasive breast cancer with long term follow up. GR Expression was separately evaluated in invasive tumor cells, stromal cells and tumor infiltrating lymphocytes (TIL's). Staining pattern was categorised as positive when more than 1% of the cells stained in each subpopulation of cells. Disease free survival was analysed between GR positive and negative status by Kaplan Meier analysis. Results: Of the 175 tumors, 121 (70%) were ER positive, 53 (30%) were ER negative and 29% (51) were triple negative. 74% (130/175) tumors showed expression of GR in invasive tumor cells while (84%) 147/175 had expression in TIL's. No significant difference in distribution of GR was noted between ER positive and ER negative tumors (78% vs 66%, p-0.1). Of the TNBC's 54% (28/51) and 70% (36/51) showed expression of GR in invasive tumor and TIL's respectively. Overall, GR positive tumors had significant better survival than GR negative tumors (mean survival time of 85 vs 59 months respectively, p-0.04) Contrary to the reports that GR expression in TIL's are associated with immunosuppressive activity in model systems, TNBC's with increased expression of GR in immune cells were associated with better survival (Mean survival time 74 vs 41 months, log rank test- p-0.03). TNBC tumors which were GR negative had higher lymph node metastases (p-0.04) and none of the other clinical features like age, menopausal state, tumor size and grade were different between GR positive and negative tumors within TNBC. Conclusions: Glucocorticoids (GC) are often used to alleviate the adverse symptoms during chemotherapy. Determining the GR status is of importance due to the pro cell survival effect of the glucocorticoids mediated through GR during chemotherapy. Though GC mediated effects on chemotherapy are controversial, our results indicate favourable effects in TNBC.

RESUMO

The biological activities of water-soluble components of edible mushroom Rubinoboletus ballouii (RB) were seldom reported. Polysaccharides of RB (RBP) were prepared and well-characterized using chemical analyses. The immunomodulatory properties of RBP were investigated using human monocyte-derived dendritic cells (moDC) in vitro, and cyclophosphamide (CTX)-induced immunosuppressive mouse model. Results showed that RBP was found to contain 80.6% (w/w) of neutral sugars including D-fucose, D-mannose, D-glucose and D-galactose (1.7:1.4:1.0:1.8), and 12.5% (w/w) of proteins, which composed of glutamine, threonine, serine, etc. RBP could promote the maturation of moDC and increase the secretion of IL-12p40, IL-10, and TNF-α. Furthermore, the stimulation of IL-12p40 production was inhibited by pretreatment with toll-like receptor (TLR)-4 blocker or NF-κB pathway blocker, suggesting that the activation of moDC by RBP was mediated through NF-κB pathway via TLR-4 receptor. On the other hand, in CTX-treated mice, RBP restored the loss of CD34bright CD45dim hematopoietic stem cells and increased IL-2 production in sera and splenocytes culture supernatant, as well as up-regulated the percentage of CD4+ T helper lymphocyte in mice splenocytes. These findings strongly suggested that RBP are the active ingredients of RB responsible for its immunostimulatory actions and deserved to be further investigated as cancer supplements.

RESUMO

Expression of ATP-binding cassette B5 (ABCB5) has been demonstrated to confer chemoresistance, enhance cancer stem cell properties and associate with poor prognosis in hepatocellular carcinoma (HCC). The aim of this study was to evaluate the genetic variations of ABCB5 in HCC patients with reference to healthy individuals and the clinicopathological significance. A pilot study has examined 20 out of 300 pairs HCC and paralleled blood samples using conventional sequencing method to cover all exons and exon/intron regions to investigate whether there will be novel variant sequence and mutation event. A total of 300 HCC and 300 healthy blood DNA samples were then examined by Sequenom MassARRAY genotyping and pyrosequencing for 38 SNP and 1 INDEL in ABCB5. Five novel SNPs were identified in ABCB5. Comparison of DNA from blood samples of HCC and healthy demonstrated that ABCB5 SNPs rs75494098, rs4721940 and rs10254317 were associated with HCC risk. Specific ABCB5 variants were associated with aggressive HCC features. SNP rs17143212 was significantly associated with ABCB5 expression level. Nonetheless, the paralleled blood and tumour DNA sequences from HCC patients indicated that ABCB5 mutation in tumours was not common and corroborated the TCGA data sets. In conclusion, ABCB5 genetic variants had significant association with HCC risk and aggressive tumour properties.

RESUMO

BACKGROUND: The dermoscopic patterns of acral melanocytic nevi (AMNs) are crucial in differentiating them from acral melanoma. Several studies have reported the dermoscopic patterns of acquired acral melanocytic nevi (AAMNs). However, few have investigated the dermoscopic patterns of congenital acral melanocytic nevi (CAMNs). OBJECTIVE: To compare the clinical and dermoscopic features of CAMNs and AAMNs. METHODS: The present study included 43 patients with CAMNs and 40 with AAMNs. We reviewed their medical records as well as their clinical and dermoscopic findings. RESULTS: Congenital acral melanocytic nevis were more asymmetrical than AAMNs (P = 0.002) and presented more frequently as comma-shaped (P = 0.005). Regarding dermoscopic findings, globular pattern (55.8%) was the most common feature of CAMNs, while parallel furrow pattern (37.5%) was the most common feature of AAMNs. The presence of fibrillar, globular, and parallel ridge patterns, and diffuse multi-component pigmentation differed significantly between the groups (P < 0.05). Furthermore, CAMNs showed melanoma-specific dermoscopic patterns, such as parallel ridge (18.6%) and diffuse multi-component pigmentation (25.6%). CONCLUSION: The dermoscopic patterns of CAMNs and AAMNs differed markedly. In terms of dermoscopic patterns, CAMNs resembled acral melanoma more often than AAMNs did.

RESUMO

BACKGROUND: Recent evidence suggests melasma to be a photoaging disorder. Triple combination creams (TCC: fluocinolone acetonide 0.01%, hydroquinone 4% and tretinoin 0.05%) remain the gold standard treatment. Picosecond alexandrite laser treatment using a diffractive lens array (DLA) has been identified to be effective for improving photoaging conditions. OBJECTIVE: We aimed to compare the efficacy and tolerance of the picosecond alexandrite laser with those of DLA and TCC in female Asian patients with melasma. METHODS: Twenty-nine patients were randomly assigned to group A1 (3 laser sessions at 4-week intervals), A2 (5 laser sessions at 4-week intervals) or B (TCC daily for at least 8 weeks and then tapered until the final evaluation). The Melasma Area, Severity Index (MASI) score and VISIA were assessed at baseline, week 12 and week 20. By week 20, the follow-up periods for groups A1 and A2 were 3 months and 1 month, respectively. RESULTS: Nine, 11 and 6 participants in groups A1, A2 and B completed the study, respectively. MASI scores were significantly improved in all 3 groups at weeks 12 and 20. In groups A1, A2 and B, the improvement rates at week 20 were 53%, 38% and 50%, respectively. VISIA® analysis additionally revealed a significant improvement in spots, porphyria, pores and brown spots after 3 laser sessions (P < 0.05). Group A2 showed greater improvements than group A1 in terms of spots, wrinkles and pores; however, only red areas were significantly different (P < 0.001). All side-effects in the 3 groups were transient and gradually subsided after 1-3 months. CONCLUSION: Picosecond alexandrite laser treatment using DLA showed comparable efficacy with TCC for the treatment of melasma. Improvements in texture, spots, wrinkles and pores were observed in the laser groups. Patients with melasma lesions that exhibit telangiectasia may benefit from additional laser treatment sessions.

RESUMO

BACKGROUND: The purpose of this experimental study was to compare the immunohistochemical expression of SOX2 and BCL-2 in Odontogenic Keratocyst (OKC) and Ameloblastoma (AB) specimens, and to identify a possible correlation in their expression. MATERIAL AND METHODS: Immunohistochemical analysis was performed to evaluate SOX2 and BCL-2 expression in OKC (n = 20) and AB (n = 20). The immunoexpression was analyzed by a quantitative and qualitative scoring system. The comparison between the immunoexpression of SOX 2 and BCL-2 was assessed by the Mann-Whitney U-test. Spearman's correlation coefficient evaluated the correlation between SOX2 and BCL-2 expressions. RESULTS: SOX2 and BCL-2 expression was observed in all specimens of OKC in the full thickness of the epithelium lining. SOX2 immunostaining was higher in OKC, in comparison with AB samples (P<0.05). BCL-2 immunostaining between OKC and AB was not statistically significant. There was no significant correlation between SOX2 and BCL-2 in OKC and AB specimens. CONCLUSIONS: SOX2 and BCL-2 expressions in OKC may suggest their relationship with the biological behavior of this lesion, and the higher expression of SOX2 might be an upstream influence on the Hh signaling pathway.

RESUMO

AIM: Few data are available on the gender-related differences in the prognostic impact of diabetes in people with heart failure. This study was performed to investigate whether there is a gender difference in the association between diabetes and long-term clinical outcomes in people hospitalized for heart failure. METHODS: A total of 3162 people hospitalized with heart failure (aged 67.4 ± 14.1 years, 50.4% females) from the data set of the nationwide registry were analysed. The primary endpoint was a composite of all-cause mortality and heart failure readmission. RESULTS: People with diabetes (30.5% for males vs. 31.1% for females, P = 0.740) were older and had more unfavourable risk factors and laboratory findings than those without diabetes in both genders. During a median follow-up period of 549 days, there were 1418 cases of composite events (44.8%). In univariable analysis, the coexistence of diabetes was significantly associated with a higher incidence of composite events in both genders (P < 0.05 each for males and females). In multivariable analysis, the prognostic impact of diabetes on the development of composite events remained significant in females even after controlling for potential confounders (hazard ratio 1.43, 95% confidence intervals 1.12-1.84; P = 0.004). However, an independent association between diabetes and composite events was not seen in males in the same multivariable analysis (P > 0.05). CONCLUSIONS: In people with heart failure, the impact of diabetes on long-term mortality and heart failure readmission seems to be stronger in females than in males. More careful and intensive management is needed especially in females with heart failure and diabetes.

RESUMO

BACKGROUND/OBJECTIVES: We investigated the effect of long-term treatment with lobeglitazone, a novel thiazolidinedione-based activator of peroxisome proliferator-activated receptor gamma, on adipose tissue (AT), focusing on its effects on insulin resistance in obese db/db mice. METHODS: Seven-week-old male db/db mice were assigned to either a vehicle-treated (n=8) or lobeglitazone-treated (n=8) group. Lobeglitazone (1 mg kg-1 daily) was injected intraperitoneally for 20 weeks. RESULTS: Lobeglitazone treatment for 20 weeks resulted in a remarkably improved glycemic index, including significantly decreased glucose levels, enhanced insulin sensitivity and preserved pancreatic beta cells. Both whole body and subcutaneous AT weight increased in the lobeglitazone-treated group. However, lobeglitazone induced an increase in the number of small adipocyte in both epididymal and subcutaneous AT, with a significant weight decrease in the epididymal AT of db/db mice. Using flow cytometry, the CD11c-positive M1 macrophages and CD206-positive M2 macrophages in the epididymal AT were observed to exhibit a decreased M1-to-M2 ratio in lobeglitazone-treated db/db mice. Furthermore, in the lobeglitazone-treated group, interscapular brown AT was clearly visualized by 18F-fluoro-2-deoxy-D-glucose positron emission tomography combined with computed tomography (18F-FDG-PET/CT) and its mass was significantly greater than that of the vehicle-treated group. In the lobeglitazone-treated group, beige-specific gene expression and the number of mitochondria in white AT were upregulated. Lobeglitazone, with upregulating interferon regulatory factor-4 (a key transcriptional regulator of thermogenesis), promoted the development of brown adipocytes and the differentiation of white adipocytes into beige adipocytes. CONCLUSIONS: Long-term lobeglitazone treatment has a beneficial role in remodeling and ameliorating inflammation in white AT and in glycemic control, in relation to insulin sensitivity in obese db/db mice. Moreover, lobeglitazone induced the differentiation of brown and beige adipocytes. Collectively, our data suggest that lobeglitazone treatment provides promising effects on white and brown AT as well as great improvement in glycemic control, as a potent insulin sensitizer.

RESUMO

Transgenic maize hybrids that express insecticidal Bacillus thuringiensis (Bt) crystalline (Cry) protein toxins effectively protect against the European corn borer, Ostrinia nubilalis, a devastating maize pest. Field monitoring and laboratory selections have detected varying levels of O. nubilalis resistance to Cry1Ab toxin. MicroRNAs (miRNAs) are short noncoding RNAs that are involved in post-transcriptional gene regulation. Their potential roles in the evolution of Bt resistance, however, remain largely unknown. Sequencing of small RNA libraries from the midgut of Cry1Ab-susceptible and resistant O. nubilalis larvae resulted in the discovery of 277 miRNAs, including 248 conserved and 29 novel. Comparative analyses of miRNA expression profiles between the laboratory strains predicted 26 and nine significantly up- and down-regulated transcripts, respectively, in the midgut of Cry1Ab resistant larvae. Amongst 15 differentially regulated miRNAs examined by quantitative real-time PCR, nine (60%) were validated as cosegregating with Cry1Ab resistance in a backcross progeny. Differentially expressed miRNAs were predicted to affect transcripts involved in cell membrane components with functions in metabolism and binding, and the putative Bt-resistance genes aminopeptidase N and cadherin. These results lay the foundation for future investigation of the potential role of miRNAs in the evolution of Bt resistance.

RESUMO

BACKGROUND: Microbial colonization of the airway plays a role in the pathogenesis of asthma; however, the effect of the upper airway microbiome on childhood asthma is not fully understood. We analyzed the metagenome of airway microbiome to understand the associated role of upper airway microbiome with the natural course of childhood asthma. METHODS: Nasopharyngeal swabs were collected from children with asthma, those in asthma remission, and control groups. High-throughput sequencing was used to examine the structure and functional dynamics of the airway microbiome with respect to asthma phenotypes. RESULTS: The composition of microbiota differed among healthy control, asthma, and remission groups. The relative abundance of Streptococcus was negatively associated with FEV1% predicted (P = .023) and that of Staphylococcus was negatively associated with methacholine PC20 (P = .013). Genes related to arachidonic acid metabolites, lysine residues, and glycosaminoglycans in the microbiome could be associated with airway inflammation. In particular, genes related to synthesis of anti-inflammatory prostaglandin E2 (PGE2 ) were not detected from the airway microbiome in the asthma group. CONCLUSIONS: These data suggest that alterations in the composition and function of the upper airway microbiome could be related with the natural course of asthma in children.

RESUMO

BACKGROUND AND OBJECTIVE: Phelligridin D is a hispidin analogue from the mushroom Phellinus baumii that is widely used as a food source in East Asia. This study tested phelligridin D for the anti-inflammatory effect and mechanism in lipopolysaccharide (LPS)-induced human periodontal ligament cells (HPDLCs). The objective of this study was to clarify whether the anti-inflammatory function of phelligridin D affects periodontal regeneration for supporting the HPDLCs of teeth. MATERIAL AND METHODS: Primary HPDLCs were isolated from healthy teeth and then cultured. The anti-inflammatory function, mechanism and differentiation molecules were verified with reactive oxygen species generation and western blot analysis in LPS-induced HPDLCs. RESULTS: HPDLCs showed increased inflammatory molecules (intracellular adhesion molecule-1 and vascular cell adhesion molecule-1) and decreased osteogenic proteins (bone morphogenetic protein-7, Osterix and runt-related transcription factor 2) by LPS treatment. Phelligridin D decreased inflammatory molecules and increased osteogenic molecules via downregulation of the extracellular signal-regulated kinase and c-jun N-terminal kinases pathway among the mitogen-activated protein kinase, followed by blocking of nuclear factor kappa-B translocation from cytosol to nucleus. In addition, phelligridin D showed antioxidant properties by reducing reactive oxygen species activity. Finally, the anti-inflammatory and antioxidant function of phelligridin D promoted the periodontal differentiation of HPDLCs. CONCLUSION: These results suggest that phelligridin D supports teeth on the alveolar bone against outside stress, and may be used as an anti-inflammatory compound for the prevention of periodontitis or periodontal regenerative related disease.

RESUMO

Radiation therapy (RT) and concurrent chemotherapy RT (CCRT) generate radiation-induced oral mucositis (OM) and lower quality of life (QOL). This study assessed the impact of a saline mouth rinse regimen and education programme on radiation-induced OM symptoms, and QOL in oral cavity cancer (OCC) patients receiving RT or CCRT. Ninety-one OCC patients were randomly divided into a group that received saline mouth rinses and an education programme and a control group that received standard care. OM symptoms and QOL were assessed with the WHO Oral Toxicity Scale, MSS-moo and UW-QOL. Data were collected at the first postoperative visit to the radiation department (T0) and at 4 weeks and 8 weeks after beginning RT or CCRT. Patients in both groups had significantly higher levels of physical and social-emotional QOL at 8 weeks after beginning RT or CCRT compared to the first visit. Patients in the saline rinse group had significantly better physical and social-emotional QOL as compared to the standard care group at 8 weeks. Radiation-induced OM symptoms and overall QOL were not different between the groups. We thus conclude the saline rinse and education programme promote better physical and social-emotional QOL in OCC patients receiving RT/CCRT.

RESUMO

The purpose of this study was to determine factors associated with self-perceived body image in female patients with head and neck cancer (HNC), and factors associated with healthcare professional's rating of disfigurement, as well as the correlation between patient and observer ratings. This cross-sectional study recruited 105 women with HNC at a large medical centre. Measures of facial disfigurement and body image, as well as demographic and clinical characteristics, were collected. Multivariate multiple linear regression modelling was used to identify factors associated with healthcare professional's rating of disfigurement and patient self-perceived body image. Disfigurement ratings by healthcare professionals were positively associated with patient self-perceived body image. Medical treatment, cancer stage, radiation dose and cancer site were significantly associated with disfigurement. Medical treatment was an important predictor of perceived body image. These findings indicate a moderate prevalence of disfigurement among women with HNCs. Patients with more disfigurement were more likely to have dissatisfaction with their body image. Nursing professionals need to carefully assess the appearance of women with HNC. Camouflage interventions can be used to help appropriately cope with the disfigurement, and to achieve improved satisfaction with their body image.

RESUMO

BACKGROUND: Acquired bilateral telangiectatic macules (ABTM) are a newly recognized disease entity, which manifest as multiple telangiectatic pigmented macules confined mostly to the upper arms. OBJECTIVES: To evaluate clinical and dermoscopic features in a group of 50 patients with ABTM and to determine the diagnostic usefulness of dermoscopy in ABTM. METHODS: Patients were selected from two tertiary teaching hospitals in Korea [Pusan National University Hospitals (Busan and Yangsan)]. Fifty patients (41 males and 9 females; mean age 48.1 years; range 26-78 years) with ABTM were included in the study. The dermoscopic findings were graded using a 4-point scale: none (0), mild (1), moderate (2) and severe (3). In addition, the results of 23 patients with and 27 patients without chronic liver disease (CLD) were compared to determine whether the presence of CLD affects dermoscopic findings. RESULTS: Three distinct dermoscopic patterns were observed; brown pigmentations, telangiectasia (linear-irregular vessels) and an angioid streak pattern. Brown pigmentation in the group without CLD had higher severity score than those in CLD group (mean score: 2.00 vs. 1.48, P = 0.033). However, mean telangiectasia severity score was higher in the CLD group (2.14 vs. 1.39, P < 0.001). The angioid streak pattern was more severe and more common in patients with CLD than in those without [1.37 vs. 0.35 (P < 0.001) and 63.0% vs. 26.1%, respectively]. CONCLUSIONS: Detailed observations with dermoscopy can provide first clues of the presence of ABTM and underlying chronic liver disease.

RESUMO

BACKGROUND: Trachyonychia can be refractory to conventional treatments including topical, intralesional or systemic corticosteroids, as well as cyclosporine and retinoids. Therefore, new treatment options are needed for recalcitrant trachyonychia. OBJECTIVE: To evaluate the efficacy and safety of oral alitretinoin for idiopathic recalcitrant trachyonychia. METHODS: A total of 21 adult patients with 210 nails affected by idiopathic recalcitrant trachyonychia were evaluated in this open-label prospective study. All patients took 30 mg of alitretinoin daily for at least 3 months. Clinical outcomes were assessed using the Physician Global Assessment (PGA) scale proposed by Park et al. (degree of roughness: 0, clear; 1, mild; 2, moderate; 3, marked; 4, severe) at baseline and 1, 3 and 6 months after treatment. RESULTS: After 1, 3 and 6 months of treatment, 74.3% (123/210), 98.1% (206/210) and 99.2% (119/120) of nails showed clinical improvement, respectively; 0% (0/210), 22.9% (48/210) and 69.2% (83/120) were completely free from nail abnormalities. The mean PGA score at baseline was 3.4, decreasing significantly to 2.7, 1.3 and 0.7 at 1, 3 and 6 months following treatment, respectively. LIMITATIONS: A small number of participants and lack of a control group were limitations. CONCLUSIONS: For the first time, this study evaluated the efficacy and safety of oral alitretinoin for idiopathic recalcitrant trachyonychia in adults. The results suggest that oral alitretinoin can be a good treatment option for adult patients with recalcitrant trachyonychia.

RESUMO

A number of clinical guidelines on nutrition therapy in cancer patients have been published by national and international societies; however, most of the reviewed data focused on gastrointestinal cancer or non-cancerous abdominal surgery. To collate the corresponding data for esophageal cancer (EC), a consensus panel was convened to aid specialists from different disciplines, who are involved in the clinical nutrition care of EC patients. The literature was searched using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the ISI Web of Knowledge. We searched for the best evidence pertaining to nutrition therapy in the case of EC. The panel summarized the findings in 3 sections of this consensus statement, based on which, after the diagnosis of EC, an initial distinction is made between the patients, as follows: (1) Assessment; (2) Therapy in patients with resectable disease; patients receiving chemotherapy or chemoradiotherapy prior to resection, and patients with unresectable disease, requiring chemoradiotherapy or palliative therapy; and (3) Formula. The resulting consensus statement reflects the opinions of a multidisciplinary group of experts, and a review of the current literature, and outlines the essential aspects of nutrition therapy in the case of EC. The statements are: Patients with EC are among one of the highest risk to have malnutrition. Patient generated suggestive global assessment is correlated with performance status and prognosis. Nutrition assessment for patients with EC at the diagnosis, prior to definitive therapy and change of treatment strategy are suggested and the timing interval can be two weeks during the treatment period, and one month while the patient is stable. Patients identified as high risk of malnutrition should be considered for preoperative nutritional support (tube feeding) for at least 7-10 days. Various routes for tube feedings are available after esophagectomy with similar nutrition support benefits. Limited intrathoracic anastomotic leakage postesophagectomy can be managed with intravenous antibiotics and self-expanding metal stent (SEMS) or jejunal tube. Enteral nutrition in patients receiving preoperative chemotherapy or chemoradiation provides benefits of maintaining weight, decreasing toxicity, and preventing treatment interruption. Tube feeding or SEMS can offer nutrition support in patients with unresectable esophageal cancer, but SEMS is not recommended for those with neoadjuvant chemoradiation before surgery. Enteral immunonutrition may preserve lean body mass and attenuates stress response after esophagectomy. Administration of glutamine may decrease the severity of chemotherapy induced mucositis. Enteral immunonutrition achieves greater nutrition status or maintains immune functions during concurrent chemoradiation.
