Edwardsiella tarda is very seldom a cause for gastroenteritis in humans. This organism can also cause extraintestinal infections, such as soft tissue infections, meningitis, peritonitis, osteomyelitis, endocarditis and hepatobiliary tract disease, particularly in the setting of compromised immunity. We describe, for the first time a case of E. tarda sepsis with multiple liver abscesses associated with Cushing's syndrome as a result of recreational aquatic exposure. 相似文献

Gardner's syndrome occurs when mutation of the adenomatous polyposis coli gene is associated with extra-intestinal manifestations in addition to colorectal adenomas. Only eleven cases of gallbladder adenoma in Gardner's syndrome have been previously reported in the literature. We report a case of Gardner's syndrome in which multiple adenomas are associated with unicryptal adenomas. 相似文献

A case of reactive plasmacytosis mimicking multiple myeloma in a patient with primary Sjogren's syndrome 总被引:1,自引:0,他引:1
Primary Sjogren's syndrome (pSS) is a chronic autoimmune disease with well-documented association of lymphoid malignancies during the progress of the disease. Although several types of malignancy and pseudomalignancy have been reported in pSS, low-grade non-Hodgkin's lymphomas are the most frequently observed. Reactive plasmacytosis mimicking myeloma is a very rare condition in association with pSS. We describe a 72-yr-old woman with pSS who presented with hypergammaglobulinemia, and extensive bone marrow and lymph node plasmacytosis, which mimicked multiple myeloma. In this patient, there was an abnormal differentiation of memory B cells to plasma cells in the peripheral blood suggesting underlying pathogenetic mechanism for this condition. 相似文献

Acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome is a rare condition belonging to the group of ectodermal dysplasias caused by TP63 mutations. Its clinical phenotype is similar to ectrodactyly-ectodermal dysplasia-cleft lip/palate (EEC) and limb-mammary syndrome (LMS), and differs from these disorders mainly by the absence of cleft lip and/or palate. We report on a 39-year-old patient who was found to be heterozygous for a c.401G > T (p.Gly134Val) de novo mutation of TP63. This patient had the ADULT phenotype associated with cleft palate. Our findings, rather than extend the clinical spectrum of ADULT syndrome, suggest that cleft palate can no longer be considered an element for differential diagnosis for ADULT, EEC, and LMS. Our data, added to other reports on overlapping phenotypes, support the combining of these three phenotypes into a unique entity that we propose to call "ELA syndrome," which is an acronym of ectrodactyly-ectodermal dysplasia-cleft lip and palate, limb-mammary, and ADULT syndromes. 相似文献

The aim of this study was to investigate the production of anti-Ro/SS-A and anti-La/SS-B antibodies in peripheral blood (PB) of patients with Sjögren's syndrome (SS). The ELISPOT method was performed to quantify the frequency of PB lymphocytes spontaneously secreting anti-Ro/SS-A and/or anti-La/SS-B antibodies. The total number of IgG-, IgA- and IgM-producing cells was also quantified. The recombinant Ro 52-kD, Ro 60-kD and La 48-kD proteins were used as target antigens. Three of 18 SS patients had PB lymphocytes secreting IgG antibodies against the recombinant Ro 52-kD protein. The same three patients had high serum titres of anti-Ro 52-kD antibodies. In addition, these patients were classified as having severe disease, and all three had focus scores of ≥ 8 in biopsies of the labial salivary glands (LSG). The correlation between the number of PB cells producing IgG antibodies against the recombinant Ro 52-kD protein and the focus score was significant (P < 0.01). The results indicate that only SS patients with severe disease and high degree of local inflammation in LSG have B cells producing anti-Ro/SS-A antibodies in PB. Thus, most of the spontaneous autoantibody production must take place in other body compartments, e.g. in exocrineglands and probably also in the lymphoid organs and/or other mucosal sites. 相似文献

Up‐regulated expression of Ro52/tripartite motif‐containing protein 21 (TRIM21), Ro60/TROVE domain family, member 2 (TROVE2) and lupus LA protein/Sjögren's syndrome antigen B (La/SSB) autoantigens has been described in the salivary gland epithelial cells (SGEC) of patients with Sjögren's syndrome (SS). SGECs, the key regulators of autoimmune SS responses, express high levels of surface functional Toll‐like receptor (TLR)‐3, whereas Ro52/TRIM21 negatively regulates TLR‐3‐mediated inflammation. Herein, we investigated the effect of TLR‐3‐signalling on the expression of Ro52/TRIM21, as well as Ro60/TROVE2 and La/SSB autoantigens, by SGECs. The effect of TLR‐3 or TLR‐4 stimulation on autoantigen expression was evaluated by polyI:C or lipopolysaccharide (LPS) treatment, respectively, of SGEC lines (10 from SS patients, 12 from non‐SS controls) or HeLa cells, followed by analysis of mRNA and protein expression. PolyI:C, but not LPS, resulted in a two‐step induction of Ro52/TRIM21 mRNA expression by SGECs, a 12‐fold increment at 6 h followed by a 2·5‐fold increment at 24–48 h, whereas it induced a late two‐fold up‐regulation of Ro60/TROVE2 and La/SSB mRNAs at 48 h. Although protein expression levels were not affected significantly, the late up‐regulation of Ro52/TRIM21 mRNA was accompanied by protein redistribution, from nucleolar‐like pattern to multiple coarse dots spanning throughout the nucleus. These late phenomena were mediated significantly by interferon (IFN)‐β production, as attested by cognate secretion and specific inhibition experiments and associated with IFN regulatory factor (IRF)3 degradation. TLR‐3‐signalling had similar effects on SGECs obtained from SS patients and controls, whereas it did not affect the expression of these autoantigens in HeLa cells. TLR‐3 signalling regulates the expression of autoantigens by SGECs, implicating innate immunity pathways in their over‐expression in inflamed tissues and possibly in their exposure to the immune system. 相似文献

In the summer of 2008, a 15-year-old boy was hospitalized in a paediatric intensive care unit in the Czech Republic. Laboratory diagnosis of hantavirus infection was established by serological and molecular methods. Sequence and phylogenetic analyses showed that the causative strain was Dobrava/Belgrade virus, which is genetically closer to strains associated with Apodemus flavicollis rodents. 相似文献

The aim of this study was to investigate the production of anti-Ro/SS-A antibodies in labial salivary glands (LSG) and peripheral blood (PB) of Sjögren's syndrome (SS) patients. The ELISPOT method was performed to quantify the frequency of LSG lymphocytes and PB lymphocytes spontaneously secreting anti-Ro/SS-A antibodies. The total number of IgG-, IgA- and IgM-producing cells was also quantified. The bovine Ro 60-kD protein was used as target antigen. Six of six primary SS patients had LSG B cells producing anti-bovine Ro 60 kD of the IgG isotype, and two of two primary SS patients had in addition PB lymphocytes producing anti-bovine Ro 60 kD of the IgG isotype. The six patients who had IgG antibodies against the Ro/SS-A antigen in LSG all had focus scores of ≥ 7 in biopsies of LSG. The results indicate that SS patients with a high degree of local inflammation in LSG have B cells producing anti-Ro/SS-A antibodies in both LSG and PB. Thus, the anti-Ro/SS-A antibodies may have pathogenic importance in the progression of the exocrinopathy of SS. 相似文献

Sjögren's syndrome is a chronic illness manifested characteristically by immune injury to the salivary and lacrimal glands, resulting in dry mouth/eyes. Anti‐Ro [Sjögren's syndrome antigen A (SSA)] and anti‐La [Sjögren's syndrome antigen B (SSB)] autoantibodies are found frequently in Sjögren's subjects as well as in individuals who will go on to develop the disease. Immunization of BALB/c mice with Ro60 peptides results in epitope spreading with anti‐Ro and anti‐La along with lymphocyte infiltration of salivary glands similar to human Sjögren's. In addition, these animals have poor salivary function/low saliva volume. In this study, we examined whether Ro‐peptide immunization produces a Sjögren's‐like illness in other strains of mice. BALB/c, DBA‐2, PL/J, SJL/J and C57BL/6 mice were immunized with Ro60 peptide‐274. Sera from these mice were studied by immunoblot and enzyme‐linked immunosorbent assay for autoantibodies. Timed salivary flow was determined after pharmacological stimulation, and salivary glands were examined pathologically. We found that SJL/J mice had no immune response to the peptide from Ro60, while C57BL/6 mice produced antibodies that bound the peptide but had no epitope spreading. PL/J mice had epitope spreading to other structures of Ro60 as well as to La, but like C57BL/6 and SJL/J had no salivary gland lymphocytic infiltration and no decrement of salivary function. DBA‐2 and BALB/c mice had infiltration but only BALB/c had decreased salivary function. The immunological processes leading to a Sjögren's‐like illness after Ro‐peptide immunization were interrupted in a stepwise fashion in these differing mice strains. These data suggest that this is a model of preclinical disease with genetic control for epitope spreading, lymphocytic infiltration and glandular dysfunction. 相似文献

Noonan syndrome (NS), the most common of the RASopathies, is a developmental disorder caused by heterozygous germline mutations in genes encoding proteins in the RAS‐MAPK signaling pathway. Noonan‐like syndrome with loose anagen hair (NSLH, including NSLH1, OMIM #607721 and NSLH2, OMIM #617506) is characterized by typical features of NS with additional findings of macrocephaly, loose anagen hair, growth hormone deficiency in some, and a higher incidence of intellectual disability. All NSLH1 reported cases to date have had an SHOC2 c.4A>G, p.Ser2Gly mutation; NSLH2 cases have been reported with a PPP1CB c.146G>C, p.Pro49Arg mutation, or c.166G>C, p.Ala56Pro mutation. True cleft palate does not appear to have been previously reported in individuals with NS or with NSLH. While some patients with NS have had growth hormone deficiency (GHD), other endocrine abnormalities are only rarely documented. We present a female patient with NSLH1 who was born with a posterior cleft palate, micrognathia, and mild hypotonia. Other findings in her childhood and young adulthood years include hearing loss, strabismus, and hypopituitarism with growth hormone, thyroid stimulating hormone (TSH), and gonadotropin deficiencies. The SHOC2 mutation may be responsible for this patient's additional features of cleft palate and hypopituitarism. 相似文献
