Abstract
BACKGROUND Solitary rectal ulcer syndrome (SRUS) is a rare rectal disease with unknown etiology. Data on the genetic background in SRUS is lacking. CASE SUMMARY Here, we report the first case of SRUS in a mother-son relationship. Gene sequencing was conducted on the whole family, which revealed an inherited CHEK2 p.H371Y mutation. The experiment preliminarily revealed that the CHEK2 mutation did not affect the expression of CHEK2 protein, but affected the function of CHEK2, resulting in the expression level changes of downstream genes such as CDC25A. CONCLUSION SRUS is a genetic susceptibility disease where CHEK2 p.H371Y mutation may play a crucial role in the development and prognosis of SRUS.

Abstract
BACKGROUND Eosinophilic gastrointestinal disease (EGID) is a disorder characterized by infiltration of eosinophils causing mucosal damage and dysfunction of the gastrointestinal tract. The endoscopic findings of eosinophilic enteritis (EoN), an EGID variant, are nonspecific and occasionally difficult to diagnose. In contrast, chronic enteropathy associated with SLCO2A1 (CEAS) is a chronic persistent small intestinal disorder characterized by endoscopic findings such as multiple oblique and circular ulcers.
CASE SUMMARY We report the case of a 10-year-old boy who had suffered abdominal pain and fatigue for the preceding 6 mo. He was referred to our institute for investigation of suspected gastrointestinal bleeding because of severe anemia with hypoproteinemia and positive fecal human hemoglobin. The upper and lower gastrointestinal endoscopic findings were normal; however, double-balloon small bowel endoscopy showed multiple oblique and circular ulcers with discrete margins and mild constriction of the intestinal lumen in the ileum. The findings were highly consistent with CEAS, but urine prostaglandin metabolites were within normal limits, and no previously reported mutations in the SLCO2A1 gene were identified. Histological evaluation demonstrated moderate to severe eosinophilic infiltration localized to the small intestine suggesting a diagnosis of EoN. Clinical remission was maintained with montelukast and a partial elemental diet, but emergent surgery for bowel obstruction due to small intestinal stenosis was performed two years after the initial treatment.
CONCLUSION EoN should be considered in the differential diagnosis of CEAS-like small intestinal ulcerative lesions and normal urinary prostaglandin metabolite levels.

Abstract
Chronic non-specific multiple ulcers of the small intestine is a disease condition postulated in Japan. It is an uncommon gastrointestinal disease that causes chronic anemia and hypoalbuminemia by causing numerous ulcers without any histopathologically identifiable features. In recent years, it has been revealed that the mutations of SLCO2A1, which codes the prostaglandin transporter protein, are the cause of this disease;it is called the new name "chronic enteropathy associated with SLCO2A1 gene." The ileum, except the terminal ileum, is the most common place making it difficult to identify major lesions. Other than conservative treatments, such as nutrition therapy and iron supplements, no effective treatment has been identified so far. We present a case of chronic non-specific multiple ulcers of the small intestine diagnosed by capsule endoscopy and effectively treated by ferric carboxymaltose. A 48-year-old female had chronic iron deficiency anemia since around the age of 15. Because of severe anemia, the patient had upper and lower endoscopy at the age of 47 to find the source of the bleeding, but it was not detected. Except for the terminal ileum, the capsule endoscopy revealed ring-like ulcers, tape-like ulcers, and oblique ulcer scars in the ileum. Genetic analysis showed a homozygous mutation in intron 7, c.940+1G>A, indicating a definitive diagnosis of non-specific multiple ulcers of the small intestine. Anemia and anemia-related symptoms such as general malaise persisted despite continuous oral administration of iron drugs. Three intravenous injections of ferric carboxymaltose increased hemoglobin and enhanced the symptoms.

Abstract
Chronic mucocutaneous candidiasis (CMC) characterized by persistent and recurrent Candida infection of the skin, nails, and the mucosa membranes has been proposed as the major infectious phenotype in patients with gain-of-function mutation of signal transducer and activator of transcription 1 (STAT1) 1. However, viral infections caused mostly by herpesviruses, and a broad range of autoimmune disorders may also be part of the clinical phenotype. We report here on a 31 years old female patient suffering from severe mucosal aphthous mucositis and ulcers and recurrent herpes simplex for decades. We found a previously unknown heterozygous sequence variant in STAT1 (c.1219C>G; L407V) affecting the DNA-binding domain of the protein in the patient and her 4 years old daughter. We found this mutation gain-of-function (GOF) by using immunoblot and luciferase assays. We detected low proportion of IL-17A-producing CD4+ T cell lymphocytes by using intracellular staining and flow cytometry. Candida-induced secretion of IL-17A and IL-22 by mononuclear cells from the patient was markedly decreased compared to controls. These data suggest that the novel mutant allele may result in impaired differentiation of CD4+ T cells to CD4+/IL-17+ cells. The clinical phenotype of the disease in this patient was unique as it was dominated primarily by severe aphthous stomatitis and ulcerative esophagitis and only partly by typical CMC resulting in diagnostic delay. We suggest that patients with severe recurrent aphthous stomatitis and esophagitis should be evaluated for STAT1 GOF mutation. Based on the broad clinical spectrum of the disease, we also suggest that CMC and CMC disease may not be an appropriate term to define clinically STAT1 GOF mutation.

Abstract
BACKGROUND We recently reported on a hereditary enteropathy associated with a gene encoding a prostaglandin transporter and referred to as chronic enteropathy associated with SLCO2A1 gene (CEAS). Crohn’s disease (CD) is a major differential diagnosis of CEAS, because these diseases share some clinical features. Therefore, there is a need to develop a convenient screening test to distinguish CEAS from CD.
AIM To examine whether prostaglandin E major urinary metabolites (PGE-MUM) can serve as a biomarker to distinguish CEAS from CD.
METHODS This was a transactional study of 20 patients with CEAS and 98 patients with CD. CEAS was diagnosed by the confirmation of homozygous or compound heterozygous mutation of SLCO2A1. We measured the concentration of PGE-MUM in spot urine by radioimmunoassay, and the concentration was compared between the two groups of patients. We also determined the optimal cut-off value of PGE-MUM to distinguish CEAS from CD by receiver operating characteristic (ROC) curve analysis.
RESULTS Twenty Japanese patients with CEAS and 98 patients with CD were enrolled. PGE-MUM concentration in patients with CEAS was significantly higher than that in patients with CD (median 102.7 vs 27.9 μg/g × Cre, P < 0.0001). One log unit increase in PGE-MUM contributed to 7.3 increase in the likelihood for the diagnosis of CEAS [95% confidence interval (CI) 3.2-16.7]. A logistic regression analysis revealed that the association was significant even after adjusting confounding factors (adjusted odds ratio 29.6, 95%CI 4.7-185.7). ROC curve analysis revealed the optimal PGE-MUM cut-off value for the distinction of CEAS from CD to be 48.9 μg/g × Cre with 95.0% sensitivity and 79.6% specificity.
CONCLUSION PGE-MUM measurement is a convenient, non-invasive and useful test for the distinction of CEAS from CD.

Abstract
BACKGROUND Chronic enteropathy associated with SLCO2A1 gene (CEAS) is a hereditary disease caused by mutations in the SLCO2A1 gene and characterized by multiple small intestinal ulcers of nonspecific histology. SLCO2A1 is also a causal gene of primary hypertrophic osteoarthropathy (PHO). However, little is known about the clinical features of CEAS or PHO. METHODS Sixty-five Japanese patients recruited by a nationwide survey of CEAS during 2012-2016 were enrolled in this present study. We reviewed the clinical information of the genetically confirmed CEAS patients. RESULTS We identified recessive SLCO2A1 mutations at 11 sites in 46 patients. Among the 46 patients genetically confirmed as CEAS, 13 were men and 33 were women. The median age at disease onset was 16.5 years, and parental consanguinity was present in 13 patients (28%). Anemia was present in 45 patients (98%), while a single patient experienced gross hematochezia. All patients showed relatively low inflammatory markers in blood tests (median CRP 0.20 mg/dl). The most frequently involved gastrointestinal site was the ileum (98%), although no patient had mucosal injuries in the terminal ileum. Mild digital clubbing or periostosis was found in 13 patients (28%), with five male patients fulfilling the major diagnostic criteria of PHO. CONCLUSIONS The clinical features of CEAS are distinct from those of Crohn's disease. Genetic analysis of the SLCO2A1 gene is therefore recommended in patients clinically suspected of having CEAS.

Abstract
We performed a Japanese nationwide survey of pediatric-onset chronic nonspecific multiple ulcers of the small intestine between January 2000 and July 2013 in 176 institutions of pediatric surgery or pediatric gastroenterology and clarified the clinical features associated with genetic abnormalities in the Solute Carrier Organic Anion Transporter Family, Member 2A1 (SLCO2A1) gene. A total of 4 cases (3 girls and 1 boy) were diagnosed in this series, which had to be differentiated from Crohn disease, Behçet disease, tuberculosis, or drug-induced enteropathy. Clinical symptoms appeared in infants and accurate diagnosis required several years. Medical therapies for inflammatory bowel disease were administered in all patients; however, 2 of the 4 patients had mutation in the SLCO2A1 gene which are responsible for primary hypertrophic osteoarthopathy, and underwent strictureplasty or ileal resection after long-term follow-up. Pediatric gastroenterologists should include this new entity in the differential diagnosis of small intestinal ulcers and inflammatory bowel disease.

Abstract
Infantile hemangioma (IH) is the most common tumor of the pediatric age group, affecting up to 4% of newborns ranging from inconsequential blemishes, to highly aggressive tumors. Following well defined growth phases (proliferative, plateau involutional) IH usually regress into a fibro-fatty residuum. Despite the high prevalence of IH, little is known regarding the pathogenesis of disease. A reported six fold decrease in IGF2 expression (correlating with transformation of proliferative to involuted lesions) prompted us to study the IGF-2 axis further. We demonstrate that IGF2 expression in IH is strongly related to the expression of a cancer testes and suspected oncogene BORIS (paralog of CTCF), placing IH in the unique category of being the first known benign BORIS positive tumor. IGF2 expression was strongly and positively related to BORIS transcript expression. Furthermore, a stronger association was made when comparing BORIS levels against the expression of CTCF via either a percentage or difference between the two. A common C/T polymorphism at CTCF BS6 appeared to modify the correlation between CTCF/BORIS and IGF2 expression in a parent of origin specific manner. Moreover, these effects may have phenotypic consequences as tumor growth also correlates with the genotype at CTCF BS6. This may provide a framework for explaining the clinical variability seen in IH and suggests new insights regarding CTCF and BORIS related functionality in both normal and malignant states.

Abstract
Chronic nonspecific multiple ulcers of the small intestine is a rare but distinct clinical condition, characterized by multiple small intestinal ulcers of nonspecific histology and chronic, persistent gastrointestinal bleeding without nonsteroidal anti-inflammatory drug use. However, because of the term "nonspecific" in its nomenclature, some gastroenterologists have misinterpreted the disease as the condition with small intestinal ulcers caused by undetermined etiologies without considering clinical features. Such misinterpretation has led to the heterogeneity of clinicopathologic features of the disease, as well as to ambiguity regarding a possible genetic contribution. It thus seems necessary to recognize the clinical entity of the disease precisely to avoid misinterpretation. In this review, we describe the clinicopathologic features, differential diagnosis, and the possibility of a genetic contribution to the disease.

Abstract
Ulceration of primary melanomas is associated with poor prognosis yet is reported to predict benefit from adjuvant interferon. To better understand the biological processes involved, clinicopathological factors associated with ulceration were determined in 1804 patients. From this cohort, 348 primary tumor blocks were sampled to generate gene expression data using a 502-gene cancer panel and 195 blocks were used for immunohistochemistry to detect macrophage infiltration and vessel density. Gene expression results were validated using a whole genome array in two independent sample sets. Ulceration of primary melanomas was associated with more proliferative tumors, tumor vessel invasion, and increased microvessel density. Infiltration of tumors with greater number of macrophages and gene expression pathways associated with wound healing and up-regulation of pro-inflammatory cytokines suggests that ulceration is associated with tumor-related inflammation. The relative benefit from interferon reported in patients with ulcerated tumors may reflect modification of signaling pathways involved in inflammation.

Abstract
There are evidences that besides geographic tendency, interactions between genetic and environmental factors play an essential role in the pathogenesis of Behçet's disease (BD). In this study, we have evaluated the associations between rs4810485 and rs1883832 single nucleotide polymorphism (SNP)s of CD40 gene with the susceptibility and clinical findings of BD. Two hundred and eighty-five patients with BD and 225 age-matched healthy controls were enrolled in this study. The clinical findings of patients were noted. The distributions of genotypes, alleles, combined genotypes and haplotypes of these two SNPs in BD patients were compared with those in healthy controls. In further evaluation, we evaluated the patients with and without any of clinical findings with regarding to distribution of genotypes and alleles of these two SNPs. There was no significant difference concerning frequencies of genotypes, alleles, combined genotypes and haplotypes of rs4810485 and rs1883832 between patients and controls (p > 0.05 for all). Frequency of GT genotype of CD40 rs4810485 polymorphism was found to be significantly higher in patients with skin lesions (p < 0.05, OR 1.65, 95 % CI 1.02-2.64). Also, we have found significantly higher frequencies of CC genotype and C allele of CD40 rs1883832 polymorphism in patients with genital ulcers (p < 0.05 for both, OR 2.30, 95 % CI 1.07-4.94 and OR 1.78, 95 % CI 1.06-2.97, respectively). However, these significances were disappeared after Bonferroni correction. We suggest that differences in the expression levels of CD40 because of different genotypes of these two SNPs may take part in the development of skin lesions or genital ulcers in patients with BD.

Abstract
Clinical studies indicate that prostaglandins of E class (PGEs) may promote healing of tissue injury e.g., gastroduodenal and dermal ulcers. However, the precise roles of PGEs, their E-prostanoid (EP) receptors, signaling pathways including cAMP and cAMP response element-binding protein (CREB), and their relation to VEGF and angiogenesis in the tissue injury healing process remain unknown, forming the rationale for this study. Using an esophageal ulcer model in rats, we demonstrated that esophageal mucosa expresses predominantly EP2 receptors and that esophageal ulceration triggers an increase in expression of the EP2 receptor, activation of CREB (the downstream target of the cAMP signaling), and enhanced VEGF gene expression. Treatment of rats with misoprostol, a PGE1 analog capable of activating EP receptors, enhanced phosphorylation of CREB, stimulated VEGF expression and angiogenesis, and accelerated esophageal ulcer healing. In cultured human esophageal epithelial (HET-1A) cells, misoprostol increased intracellular cAMP levels (by 163-fold), induced phosphorylation of CREB, and stimulated VEGF expression. A cAMP analog (Sp-cAMP) mimicked, whereas an inhibitor of cAMP-dependent protein kinase A (Rp-cAMP) blocked, these effects of misoprostol. These results indicate that the EP2/cAMP/protein kinase A pathway mediates the stimulatory effect of PGEs on angiogenesis essential for tissue injury healing via the induction of CREB activity and VEGF expression.

Abstract
Background Despite the extensive research approaches applied to characterise malignant melanoma, no specific molecular markers are available that are clearly related to the progression of this disease. In this study, our aims were to define a gene expression signature associated with the clinical outcome of melanoma patients and to provide an integrative interpretation of the gene expression -, copy number alterations -, and promoter methylation patterns that contribute to clinically relevant molecular functional alterations. Methods Gene expression profiles were determined using the Affymetrix U133 Plus2.0 array. The NimbleGen Human CGH Whole-Genome Tiling array was used to define CNAs, and the Illumina GoldenGate Methylation platform was applied to characterise the methylation patterns of overlapping genes. Results We identified two subclasses of primary melanoma: one representing patients with better prognoses and the other being characteristic of patients with unfavourable outcomes. We assigned 1,080 genes as being significantly correlated with ulceration, 987 genes were downregulated and significantly enriched in the p53, Nf-kappaB, and WNT/beta-catenin pathways. Through integrated genome analysis, we defined 150 downregulated genes whose expression correlated with copy number losses in ulcerated samples. These genes were significantly enriched on chromosome 6q and 10q, which contained a total of 36 genes. Ten of these genes were downregulated and involved in cell-cell and cell-matrix adhesion or apoptosis. The expression and methylation patterns of additional genes exhibited an inverse correlation, suggesting that transcriptional silencing of these genes is driven by epigenetic events. Conclusion Using an integrative genomic approach, we were able to identify functionally relevant molecular hotspots characterised by copy number losses and promoter hypermethylation in distinct molecular subtypes of melanoma that contribute to specific transcriptomic silencing and might indicate a poor clinical outcome of melanoma.

Abstract
Background Medical male circumcision (MMC) reduces the risk of genital ulcer disease (GUD) in men by 50%. In Ugandan and Kenyan trials, a sexually transmissible agent was not identified in 50–60% of GUD specimens by polymerase chain reaction (PCR) assay. We sought to better define the etiology of GUD in men participating in the Kenyan trial and examine how MMC affects GUD etiology. Methods We defined GUD of unknown etiology as negative for HSV (type 1 and type 2), T. pallidum, and H. ducreyi by PCR, and negative for HSV-2 and T. pallidum by serology. We identified bacterial microbiota in a subset of 59 GUD specimens using multitag pyrosequencing of the 16S rRNA gene, and compared results by unknown vs. STI-associated etiology. Statistical analysis employed Bray-Curtis similarity measure of bacterial community by etiology, hierarchical clustering and logistic regression. Results In 59 GUD specimens from 59 men, 23 (39%) had unknown etiology. Bacterial diversity was greater in GUD of unknown than STI etiology (p = 0.01). Fusobacteria (Fusobacterium spp. and Sneathia spp.) were more commonly detected in men with GUD of unknown etiology [adjusted OR = 5.67; 95% CI: 1.63–19.8] as were Oxobacter spp. and Anaerovorax spp. [adjusted OR = 3.12; 95% CI: 0.83–11.7]. Sequences from these four anaerobic bacterial taxa were more often detected in uncircumcised men than circumcised men (p<0.05). Conclusions Anaerobic bacteria are more common in genital ulcers of uncircumcised men. The specific anaerobic bacteria associated with GUD of unknown etiology have cytotoxic properties that can exacerbate epithelial disruptions leading to ulcer-like appearance. MMC may reduce GUD through a reduction in these anaerobic bacteria.

Abstract
BTB and CNC homolog 1 (Bach1) is a transcriptional repressor of heme oxygenase-1 (HO-1). It plays an important role in the feedback regulation of HO-1 expression, which protects cells from various insults including oxidative stress and inflammatory cytokines. However, the role of Bach1 in intestinal inflammation remains unclear. In this study, the role of Bach1 in intestinal mucosal injury was elucidated using 8-week-old female C57BL/6 (wild-type) and homozygous Bach1-deficient C57BL/6 mice. Intestinal mucosal injuries induced by a single subcutaneous administration of indomethacin were evaluated macroscopically, histologically, and biochemically. Mucosal protein content and chemokine mRNA levels were determined by real-time PCR. Our results showed that the indomethacin-induced intestinal injury was remarkably improved in Bach1-deficient mice. Histological examination showed that the area of injured lesion was decreased in Bach1-deficient mice compared to wild-type mice. Administration of indomethacin induced expression of inflammatory chemokines such as KC, MIP1alpha and MCP1, which was suppressed in Bach1-deficient mice. Myeloperoxidase activity in the intestinal mucosa was also significantly decreased in Bach1-deficient mice. Additionally, Bach1 deficiency enhanced immunopositivity of HO-1 in the intestinal mucosa after indomethacin administration. Disruption of the Bach1 gene thus caused inhibition of mucosal injury, indicating that inhibition of Bach1 may be a novel therapeutic strategy for treating indomethacin-induced intestinal injury.

Abstract
OBJECTIVE Behçet's disease (BD) is an autoimmune disease with an unknown etiology and mannose-binding lectin (MBL) is a pattern recognition receptor in the innate immune system, which is associated with some autoimmune diseases. We investigated MBL2 gene polymorphisms and serum MBL levels in BD patients and controls. METHODS MBL2 gene polymorphisms in exon 1 (MBL2 54 Gly/Asp, (A/B)), promoter (MBL2 H/L (G-550C), MBL2 Y/X (G-221C)), and 5' UTR region (MBL2 P/Q (C+4T)) were investigated using polymerase chain reaction and restriction fragment length polymorphism in 119 BD patients and 252 healthy controls. Serum MBL levels were measured by enzyme linked immunosorbent assay in 49 BD patients and 102 sex-/genotype-matched controls. RESULTS No significant difference was found between BD patients and controls in terms of MBL2 polymorphisms and MBL serum levels. However, the presence of genital ulcer and neurologic involvement were found to be associated with MBL2 54 allele A (OR=2.415, OR=6.632, respectively). Eye involvement was found to be related to the presence of the MBL2 54 AA or AB genotypes (OR=12.46), MBL2-G-550C allele H (OR=1.829). High serum MBL level (> or =500 ng/ml) was associated with skin lesions (p=0.002). CONCLUSION The frequencies of the four MBL2 genetic polymorphisms examined were not different in BD patients and healthy controls. However, the presence of genital ulcer, eye involvement, and neuro-Behcet's disease were found to be associated with MBL2 polymorphisms that are associated with the production of high levels of MBL or functional MBL.

Abstract
Idiopathic ulcerative dermatitis is a well-recognized disease in C57BL mice and related strains. This disease manifests as a pruritic dermatitis with resulting self-mutilation, dermal ulceration, necrosis, and fibrosis. Ulcerative dermatitis has the ability to confound ongoing research by causing systemic pathologic changes, such as lymphadenopathy and splenomegaly. Although various treatments have been described, none has been curative consistently; therefore, minimizing negative effects on research through prevention of disease is ideal. To identify etiologic factors, we conducted a 2-y retrospective study of 1352 mice with a C57BL/6 genetic background; these mice demonstrated an overall prevalence of 4.1% and a seasonal effect with a peak incidence during midsummer. Corroborating previous studies, our study revealed a disease predilection for female mice. In contrast to prior reports, the disease prevalence was greatest in 10- to 16-mo-old mice. In addition, mice with a C57BL/6 background that were deficient in the gene for inducible nitric oxide synthase had a 50% disease incidence, suggesting a potential animal model for further characterizing the pathogenesis, prevention, and treatment of ulcerative dermatitis.

Abstract
Our previous studies demonstrated that enhanced epithelial cell proliferation is important for healing of experimental esophageal ulcers. However, the roles of angiogenesis, its major mediator, vascular endothelial growth factor (VEGF), and the mechanism(s) regulating VEGF expression during esophageal ulcer healing remain unknown. Esophageal ulcers were induced in rats by focal application of acetic acid. We studied expressions of hypoxia-inducible transcription factor-1 alpha (HIF-1 alpha), an activator of the VEGF gene, and VEGF by reverse transcriptase-polymerase chain reaction, Western blotting, and immunostaining. To determine the efficacy of VEGF gene therapy in esophageal ulcer healing, we studied whether a single local injection of plasmid cDNA encoding recombinant human VEGF(165) affects ulcer healing and angiogenesis. Esophageal ulceration induced HIF-1 alpha protein expression and VEGF gene activation reflected by increased VEGF mRNA (240%) and VEGF protein (310%) levels. HIF-1 alpha protein was expressed in microvessels bordering necrosis where it co-localized with VEGF. Injection of cDNA encoding VEGF(165) significantly enhanced angiogenesis and accelerated esophageal ulcer healing. These results: 1) suggest that HIF-1 alpha may mediate esophageal ulceration-triggered VEGF gene activation, 2) indicate an essential role of VEGF and angiogenesis in esophageal ulcer healing, and 3) demonstrate the feasibility of gene therapy for the treatment of esophageal ulcers.

Abstract
Although most colorectal cancer develops based on the adenoma-adenocarcinoma sequence, morphologically, colorectal cancer is not a homogeneous disease entity. Generally, there are two distinct morphological types: polypoid and ulcerative colorectal tumours. Previous studies have demonstrated that K-ras codon 12 mutations are preferentially associated with polypoid growth of colorectal cancer; however, little is known about the molecular mechanism that determines ulcerative growth of colorectal cancer. beta-catenin complex plays a critical role both in tumorigenesis and morphogenesis. We examined the differential expression of beta-catenin and its related factors among different types of colorectal cancer in order to determine any relationship with gross tumour morphology. Immunohistochemical staining of beta-catenin, E-cadherin and MMP-7 was performed on 51 tumours, including 26 polypoid tumours and 25 ulcerative tumours. Protein truncation tests and single-strand conformational polymorphism for mutation of the adenomatous polyposis coli tumour suppressor gene, as well as single-strand conformational polymorphism for the mutation of beta-catenin exon 3 were also done. Nuclear expression of beta-catenin was observed in 18 out of 25 (72%) cases of ulcerative colorectal cancer and seven out of 26 (26.9%) cases of polypoid colorectal cancer. A significant relationship of nuclear beta-catenin expression with ulcerative colorectal cancer was found (P<0.001). However, this finding was independent of adenomatous polyposis coli tumour suppressor gene mutation and E-cadherin expression. Together with previous data, we propose that different combinations of genetic alterations may underlie different morphological types of colorectal cancer. These findings should be taken into consideration whenever developing a new genetic diagnosis or therapy for colorectal cancer.

Abstract
BACKGROUND Trauma patients are at risk for the development of stress ulceration. Stress ulceration should be associated with increased heat-shock gene (iHSP70) and an inhibition of the trefoil peptide, spasmolytic polypeptide (SP), and mucin (MUC5AC) gene expressions. METHODS Male Sprague-Dawley rats (10 weeks old) were restrained for 0-, 4-, 8-, 12-, and 24-hour periods of time. Gastric ulcers were graded using a one- to three-point scoring system. The level of mucosal gene expression was determined at each time point for three genes: iHSP70, SP, and MUC5AC. RESULTS Gastric ulceration developed in direct proportion to the duration of restraint. Gastric ulceration was preceded by increased iHSP70 and decreased SP and MUC5AC gene expressions. CONCLUSION Restraint-induced gastric ulceration was preceded by an up-regulation of iHSP70 and a down-regulation of SP and MUC5AC gene expressions.

Abstract
BACKGROUND & AIMS Differences in genetic background may play a role in the development of ulcerative colitis (UC)-related neoplasia. Loss of heterozygosity (LOH) of APC has been reported in human UC-associated neoplasia. To investigate the role of genetic differences in UC-associated neoplasia, we compared differences in dextran sodium sulfate (DSS) colitis-associated neoplasia between wild-type C57BL/6J mice (WT-DSS) and C57BL/6J mice with a germline mutation in Apc (Min-DSS). METHODS DSS colitis was induced in female wild-type and Min mice. Age- and sex-matched non-DSS-treated Mins were also studied. Animals were sacrificed after 1 and 2 cycles of DSS. The cecums and large intestines were studied for numbers of dysplasias/cancers. Dysplasias were studied for LOH of Apc. RESULTS No WT-DSS, 100% of Min-DSS, and 50% of non-DSS-treated Mins had dysplasia. The mean numbers of lesions per mouse were 0 (WT-DSS), 15.6 and 29.3 (1 and 2 cycles Min-DSS, respectively), 1.2 and 1.9 (age-matched control Min, 1 and 2 cycle equivalents, respectively; P < 0.0002, Min-DSS vs. WT-DSS and non-DSS-treated Min; P = 0.03, Min-DSS 2 cycle vs. Min-DSS 1 cycle). Cancers were seen in 0%, 22%, and 40% of non-DSS Min, Min-DSS-1 cycle, and Min-DSS-2 cycle animals, respectively. LOH of Apc was observed in 90.6% of dysplasias and 6% of nondysplastic mucosa. CONCLUSIONS A germline mutation in Apc contributes significantly to the development of colitis-associated neoplasia. Colitis markedly accelerates the development of dysplasia and cancer in the Min mouse. Dysplasia in Min-DSS occurs through LOH of Apc.

Abstract
We identified a novel mutation in an asymptomatic 65-year-old Japanese man with severe factor XI deficiency. Sequence analysis after polymerase chain reaction single-stranded conformation polymorphism (PCR-SSCP) analysis of his factor XI gene revealed a G-->A transition in codon 501 of exon 13, resulting in a substitution of Trp501 (TGG) by a stop codon (TAG) in the catalytic domain. This mutation abolished a FokI restriction site. The PCR product from normal subjects was digested with FokI and yielded two fragments, one of 223 bp and one of 47 bp. The PCR product from the patient gave a single 270-bp fragment, demonstrating possible homozygosity.

Abstract
In the present study, right hind limb bones from 46 12-month-old bulls with no clinical signs were examined to identify and describe lesions that could predispose the stifle and tarsal joints to osteoarthritis. The bulls came from a performance testing station and were slaughtered due to a low index at the end of the testing period 1996-97. Differences in frequency of lesions among breeds as well as the relationship between lesions and growth rate were evaluated. Forty-five (97.8%) of the 46 bulls had lesions in the joints and/or growth plates. Prevalence of lesions was 100% in the Charolais (22/22), the Hereford (8/8), and the Limousin (4/4) breeds, and 85.7% (6/7) in the Simmental breed. The stifle was affected in 37, the tarsus in 33, and the growth plates in 34, of the 46 bulls. Lesions found in the stifle joint were: osteochondrosis of the articular-epiphysical cartilage complex (AECC) (25), subchondral bone cyst of the distal femur (1), fragmentation of the medial intercondylar eminence of the tibia (20), cleft in the distal part of the patellar groove (28), and an avulsion fracture of the lateral condyle together with a partial tear of the cranial cruciate ligament (1). Lesions found in the tarsal joint were: osteochondrosis of the AECC (23), ulcerative lesions of the articular cartilage of the talus (25), and fracture of the medial malleolus (4). Twenty-eight bulls had lesions of osteochondrosis at the AECC and 37 at the growth plates. When osteochondrosis at the AECC and thickening of the growth plates were combined, 44 of the 46 bulls had at least one lesion at the AECC and/or the growth plate. Prevalence of bulls with at least one lesion was similar between breeds, but the number of lesions per bull was significantly higher in Charolais followed by Simmental, Hereford, and Limousin. Number of lesions per bull was significantly correlated with daily weight gain, carcase weight, and the width of the proximal tibial epiphysis. Lesions were statistically independent, indicating that local biomechanical factors within the joints are important in the pathogenesis. In conclusion, we suggest that the high incidence of hind limb osteoarthritis reported in the Swedish beef bull population can be explained by the high prevalence of skeletal lesions found in the present material. The lesions appeared to be related to high growth rate and to the breed.

Abstract
Inheritance pattern of ulcer disease was analysed genetico-mathematically using one of the a posteriori methods--the method of maximum likelihood. We studied the families of 351 hereditary predisposed probands of whom 57 with type II gastric ulcer disease, 27 with type III gastric ulcer disease and 267 with duodenal ulcer disease. The types of ulcer disease were determined according to H. Johnson. The analysis of the patients with duodenal ulcer also included the types of familial predisposition of the probands. The results yielded by the maximum likelihood method excluded to a great degree the possibility of monogenic transmission of ulcer disease. None to the three types of peptic ulcer showed autosomal recessive pattern of inheritance; it was not found even in the families with phenotypically healthy but hereditary predisposed parents. No evidence was found of autosomal dominant pattern of inheritance of the disease in all studied groups including the families with one sick parent. This is supported by the different values of the segregation coefficients in the families with one sick father and one sick mother. The absence of evidence for monogenic mode of inheritance of the disease indicated by the detailed genetico-mathematical analysis should be further evaluated by the criteria of polygenicity.

Abstract
A 39-year-old woman had relapsing polychondritis and Behçet's disease, which was described as mouth and genital ulcers with inflamed cartilage syndrome (MAGIC). Serologic human leukocyte antigen analysis showed A24 (9), A31 (19), B56 (22), B62 (15), Cw6, DR4, DR9. Human leukocyte antigen allele analysis revealed DRB1* 0406/0901, DQA1* 0301/0301, DQB1* 0302/0303, DPB1* 0201/0501 through determining the genotype using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Treatment with methotrexate (5 mg/week) and pentoxifylline (300 mg/d) was effective to control oral ulcers, erythema nodosum, and arthritis.

Abstract
The full Feulgen hydrolysis profiles of healthy and malignant oral epithelial cells were compared by measuring the staining density of nuclei using microdensitometry after varying hydrolysis times. Malignant nuclei contained significantly increased levels of acid-labile DNA. The relative amounts of the rapidly hydrolysable fraction were compared after 5 min hydrolysis for exfoliating epithelial cells from healthy oral mucosa, healing chronic ulcers and squamous cell carcinomas. Although the latter exhibited a wide range of values, analysis of variance showed significant differences (P < 0.05) between healthy control and ulcer groups compared to oral carcinoma. The relative proportion of highly acid-labile DNA in malignant nuclei showed a significant positive correlation with mitotic score (P < 0.01) but no significant correlation with nuclear area. It was concluded that since the susceptibility of DNA to acid hydrolysis probably reflects functional differences in nuclear activity between cells, estimation of the highly acid-labile fraction may have diagnostic and/or prognostic value.

Abstract
We describe a multisystem disease that affects children of Muslim families originating in the Punjab region of Pakistan and India. An altered cry due to vocal cord thickening, skin ulceration, nail abnormalities, and conjunctival scarring appear in the first few months of life. Progression and spread of the disease in these sites may be accompanied by involvement of other epithelial surfaces. The teeth may exhibit defective enamel formation. Histology reveals the formation of simple granulation tissue arising in the dermis and submucosa which become massively thickened and ulcerated. There is good evidence for an autosomal recessive gene defect, but the actual mechanism of the disease is not known. Medical and surgical therapy have been ineffective in altering the course of this devastating and usually fatal condition. We suggest the term LOGIC (laryngeal and ocular granulation tissue in children from the Indian subcontinent) for this newly established disease.

Abstract
Among 50 patients with recurrent oral ulceration (ROU) the prevalence of HLA B5 was not increased as was the case among 50 patients with Behçet's Syndrome (BS) compared to 52 healthy controls. On the other hand, HLA DR4 was present in 16 of 30 (53%) patients with ROU whereas the same allele was present in 16% of BS patients and 22% of the healthy controls. These findings suggest that ROU and BS are not in the same disease spectrum.

Abstract
A case of a 46 years old male suffering from chronic sensory neuropathy is reported. The symptoms consisted of superficial and deep sensory disturbances, and bilateral trophic plantar ulcerations with osteolysis, resulting in a deformity of the feet. There was an increased sweating of the distal portions of the four limbs, and a delayed adaptation of blood pressure and heart frequency to postural changes. CSF aminoacids were all increased except taurine, which was markedly descreased. An increased blood flow in lower extremities was demonstrated angiographically. The possibilities of pharmacological and surgical treatment raised by the hemodynamic hypothesis of BUREAU and BARRIERE (1957) are discussed.

Abstract
In 4 cases of hereditary sensory radicular neuropathy the loss of pain and thermal sensibility resulting in perforating ulcers starts distally in lower extremities and progresses proximally. It has a sporadic and familial form as well as the hereditary type. In siblings inheritance appeared to be autosomal dominant. By early recognition of the disease and removing pressure from the involved areas, or spreading pressure equally over the foot with proper footwear ulcers are preventable.

Abstract
The first-degree family members of patients with Behcet's syndrome were investigated to determine (1) whether there was a familial aggregation of Behcet's syndrome or of its component features, (2) whether there was an increased incidence of sacro-iliitis in these families, and (3) whether a link exists between Behcet's syndrome and spondarthritides in first-degree relatives. Of the 226 relatives and patients seen, 21 patients with definite Behcet's syndrome and their 71 relatives were analysed in some detail. Orogenital ulceration was found in 2 mothers of probands; 1 patient had psoriasis and Behcet's but neither disease featured in the pedigree. Another family showed numerous manifestations of psoriasis and psoriatic arthritis, 1 member having severe sacro-iliitis but the proband had Behcet's syndrome only. Family trees including HLA pedigrees, where known, are presented. Spouses suffered few of the complaints found in patients, and to a less extent in relatives, but showed a high incidence of backache, perhaps of psychogenic origen.

Abstract
Six lines of Japanese quail were derived from a single foundation population. Four of the lines were selected on the basis of family mean three week body weight, two were unselected and all lines were randomly mated. Quail were housed in wire batteries during the brooding, rearing and laying periods. During the brooding period, hover temperature and floor space per chick were similar from line to line. For the rearing and laying periods, floor space per chick was approximately the same from line to line. During an outbreak of ulcerative enteritis (diagnosed on the basis of gross and histopathology) in generation 31 and again in generation 34, mortality ranged from zero for males of one control line to approximately 50 percent for females of one selected line. Analysis of variance showed that incidence of mortality differed significantly among lines and between sexes. Mortality was generally higher in selected than in control lines and in females than in males. It is suggested that susceptibility to ulcerative enteritis in quail may be a polygenically inherited trait and that the breeding which accompanied selection for body size may have made some loci homozygous for susceptibility alleles.
