Overview of the Justicia Genus: Insights into Its Chemical Diversity and Biological Potential.

The genus Justicia has more than 600 species distributed in both hemispheres, in the tropics and temperate regions, and it is used in the treatment of numerous pathologies. This study presents a review of the biological activities of plant extracts and isolated chemical constituents of Justicia (ACANTHACEAE), identified in the period from May 2011 to August 2022. We analyzed over 176 articles with various biological activities and chemical compound descriptions present in the 29 species of Justicia. These have a variety of applications, such as antioxidant and antimicrobial, with alkaloids and flavonoids (e.g., naringenin) the most frequently identified secondary metabolites. The most observed species were Justicia gendarussa Burm., Justicia procumbens L., Justicia adhatoda L., Justicia spicigera Schltdl, and Justicia pectoralis Jacq. The frontier molecular orbitals carried out using density functional theory (M062X and basis set 6-311++G(d,p) indicate reactive sites for naringenin compound and a chemical reaction on phytomedicine activity. The energy gap (206.99 kcal/mol) and dimer solid state packing point to chemical stability. Due to the wide variety of pharmacological uses of these species, this review points toward the development of new phytomedicines.

Using Cumulus Cell Biopsy as a Non-Invasive Tool to Access the Quality of Bovine Oocytes: How Informative Are They?

The present study aimed to determine whether cumulus cells (CC) biopsy, acquired before or after in vitro maturation (IVM), presents similar gene expression pattern and if would compromises oocyte quality. First, immature cumulus oocyte complexes (COCs) were distributed: (1) maturated in groups (control); (2) individually maturated, but not biopsied; (3) subjected to CC biopsy before maturation and individually matured; (4) individually matured and submitted to CC biopsy after maturation; (5) individually matured and CC biopsied before and after maturation. Secondly, candidate genes, described as potential markers of COCs quality, were quantified by RT-qPCR in CCs before and after IVM. After in vitro fertilization (IVF), zygotes were tracked and sorted regarding their developmental potential: fully developed to embryo, cleaved and arrested, and not-cleaved. The COC's biopsy negatively affects embryo development (p < 0.05), blastocyst cell number (p < 0.05), and apoptotic cell ratio (p < 0.05), both before and after IVM. The PTGS2, LUM, ALCAM, FSHR, PGR, SERPINE2, HAS2, and PDRX3 genes were differentially expressed (p < 0.05) on matured CCs. Only PGR gene (p = 0.04) was under-expressed on matured CCs on Not-Cleaved group. The SERPINE2 gene was overexpressed (p = 0.01) in the Cleaved group on immature CCs. In summary, none of the selected gene studies can accurately predict COC's fate after fertilization.

Initial panel of immunocytochemical markers for identification of primary carcinoma site for effusions and peritoneal washings from women.

INTRODUCTION: In women, most malignant effusions are from breast and ovary primary carcinomas that have metastasized to body cavity fluids (pleural, peritoneal and pericardial). When carcinoma is diagnosed in effusions, it is not possible to identify its site of origin solely by cytology (morphology); therefore, immunocytochemistry is used as a complementary method. There are no immunocytochemical markers with 100% sensitivity and specificity for identifying carcinoma primary site. The markers most used are TTF-1 for the lung, GATA-3 for the breast, and PAX-8 for the ovary. The aim of this study was to evaluate the sensitivity and specificity of a panel including these markers for detecting the primary site of carcinoma in effusions. METHODS: Samples of pleural, pericardial, and peritoneal effusions and peritoneal washings with carcinoma of known primary site from women (n = 60) and men (n = 18) were prepared by using the cell block method, and immunocytochemistry was performed to evaluate the expression of primary site markers (TTF-1, PAX-8, and GATA-3). RESULTS: In women, the breast was the most frequent primary site of metastatic carcinoma to both pleural and pericardial cavities, followed by the lung, whereas the ovary was the most frequent primary site of carcinoma within peritoneal effusions and washings, followed by the gastrointestinal tract (stomach or intestine). The expected profiles for carcinomas of the most common primary sites were: breast (GATA-3 (+), PAX-8 (-), TTF-1 (-)), ovary (PAX-8 (+), GATA-3 (-), TTF-1 (-)), lung (TTF-1 (+), PAX-8 (-) GATA-3 (-)) and gastrointestinal tract (PAX-8 (-), GATA-3 (-), TTF-1 (-)). These were observed in 88.23% (45/51) of women's samples with carcinoma from these primary sites. By using TTF-1 as the sole primary site marker, 6.25% of carcinomas of primary site other than the lung would have been misdiagnosed. CONCLUSION: An initial panel of markers including GATA-3, PAX-8, and TTF-1 allows, with high sensitivity and specificity, the identification or exclusion of frequent primary sites of carcinoma in effusions from women. Our results highlight the importance of using a panel of markers to avoid misidentification of the primary site of tumor.

RISK FACTORS ASSOCIATED WITH FRACTURE OF THE LUMBOSACRAL SPINE AND ITS COMPROMISE IN THE QUALITY OF LIFE OF CIRRHOTICS.

BACKGROUND: Chronic hepatic disease is associated with osteoporosis, osteopenia or osteomalacia. Osteoporosis and fractures due to bone fragility present high prevalences and are more frequent in patients with liver cirrhosis than in the general population. The search for a diagnosis of osteopenia and osteoporosis in this population may allow early intervention and modify unfavorable outcomes. OBJECTIVE: To know the prevalence of osteopenia or osteoporosis and of fracture due to bone fragility in individuals with liver cirrhosis, the associated risk factors, and its compromise in their quality of life (QoL). METHODS: Observational, transversal study performed with 71 liver cirrhosis patients of the Hepatology Service of the Hospital de Base do Distrito Federal, Brasília, DF, Brazil, between July 2017 and December 2018. The patients were submitted to bone densitometry (DXA) of the lumbar spine and of the femoral neck, to x-ray of the lumbosacral spine and to the Chronic Liver Disease Questionnaire (CLDQ) for the evaluation of quality of life (QoL). The Fracture Risk Assessment (FRAX) major was calculated for patients >50 years old. The analyses were performed for the evaluation of the risk factors associated with lumbosacral spine fracture. RESULTS: The majority (62%) of the 71 evaluated patients was diagnosed with osteoporosis or osteopenia on DXA. Of the 44 patients with osteopenia or osteoporosis, 52.3% were female, with a mean age of 62.6±9.51 years old, with the majority (72.7%) being Child A, cirrhotics of alcoholic etiology (36.4%), and with an intermediate QoL according to the CLDQ (3.3). Regarding the patients with lumbosacral spine fracture, the mean age was 61.6±11.1 years old, 60% were female, most of them Child A (66.7%), of alcoholic etiology (46.7%), and with an intermediary QoL according to the CLDQ (3.5). The presence of osteopenia and/or osteoporosis was associated with lumbosacral fracture (P<0.001), without correlation with the other analyzed variables: age, body mass index, gender, presence and absence of ascites, Child-Pugh classification, vitamin D, calcium, and phosphorus serum concentration, cirrhosis etiology and FRAX major. CONCLUSION: The prevalence of hepatic osteodystrophy was high, and the occurrence of lumbosacral spine fracture was more associated with osteoporosis and/or osteopenia among the cirrhotic patients studied. The QoL was intermediate and with no differences between cirrhotics with and without fracture.

Immunoglobulin G4-Associated Cholangitis: Two Case Reports and Clinical Use of Classic and Emerging International Diagnostic Criteria.

Immunoglobulin G4-related disease is a multisystem disorder with unique gastrointestinal tract manifestations, often simulating neoplasms and other inflammatory conditions. Appropriate clinical suspicion and application of internationally validated criteria can assist in making the proper diagnosis. This article describes two cases of patients presenting with biliary tract manifestations simulating lymphoproliferative disease and adenocarcinoma, respectively. Clinical, radiological, and histopathological findings ultimately led to the correct diagnosis, and revealed useful nuances for detection of future cases. Application of specific criteria, such as the classic Japan Biliary Association clinical diagnostic criteria published in 2012 and revised in 2020 as well as the 2019 American College of Rheumatology and European League Against Rheumatism (ACR/EULAR) classification criteria, has limitations but provides important warnings to be considered in the diagnostic journey of these challenging cases.

RESUMO Contexto A doença hepática crônica associa-se com osteoporose, osteopenia ou osteomalácia. A osteoporose e as fraturas por fragilidade óssea têm altas prevalências e são mais frequentes em pacientes com cirrose hepática do que na população geral. A busca por osteopenia e osteoporose nesta população pode permitir a intervenção precoce e modificar os desfechos desfavoráveis. Objetivo Conhecer a prevalência de osteopenia ou osteoporose e de fraturas por fragilidade óssea em portadores de cirrose hepática, fatores de risco associados e seu comprometimento na qualidade de vida. Métodos Estudo observacional e transversal realizado com 71 pacientes portadores de cirrose hepática do Serviço de Hepatologia do Hospital de Base do Distrito Federal, Brasília, DF, Brasil, no período de julho de 2017 a dezembro de 2018. Os pacientes foram submetidos à densitometria óssea de coluna lombar e colo de fêmur, raio-x de coluna lombo sacra e ao questionário Chronic Liver Disease Questionnaire (CLDQ, na sigla em inglês) para avaliação de qualidade de vida. Foi calculado o escore de Fracture Risk Assessment Tool "FRAX Maior" nos pacientes >50 anos. As análises foram realizadas para a avaliação dos fatores de risco associados à fratura de coluna lombo sacra. Resultados Dos 71 pacientes avaliados, a maioria (62%) foi diagnosticada com osteoporose ou osteopenia à densitometria. Dos 44 portadores de osteopenia ou osteoporose, 52,3% eram do sexo feminino, com idade média de 62,6±9,51 anos, sendo a maioria (72,7%) Child A, cirróticos de etiologia alcoólica (36,4%) e com qualidade de vida intermediária ao CLDQ (3,3). Dos pacientes com fratura de coluna lombo sacra, a média de idade foi de 61,6±11,1 anos, 60% eram do sexo feminino, a maioria Child A (66,7%), de etiologia alcoólica (46,7%), e apresentaram qualidade de vida intermediária ao CLDQ (3,5). A presença de osteopenia e/ou osteoporose esteve associada à fratura lombo sacra (P<0,001), sem correlação com as demais variáveis analisadas: idade, índice de massa corporal (IMC), gênero, presença e ausência de ascite, classificação de Child-Pugh, concentrações séricas de vitamina D, cálcio e fósforo, etiologia da cirrose e "FRAX maior". Conclusão A prevalência de osteodistrofia hepática foi elevada, e a ocorrência de fratura de coluna lombo sacra esteve mais associada à osteoporose e/ou osteopenia entre cirróticos estudados. A qualidade de vida se mostrou intermediária e sem diferença entre cirróticos com e sem fratura.

Surveillance of antimicrobial resistant bacteria in flies (Diptera) in Rio de Janeiro city.

Antimicrobial-resistant bacteria were isolated from muscoid dipterans collected at five different areas of Rio de Janeiro city, in proximity to hospitals. Extracts obtained by maceration of flies were diluted and used as inocula for different culture media, with or without antibiotic (ceftriaxone 1 mg/L) supplementation. Purified isolates were submitted to antimicrobial susceptibility testing (AST). Bacterial identification was performed by MALDI TOF Microflex LT (Bruker Daltonics). A total of 197 bacterial strains were obtained from 117 dipterous muscoids. Forty-two flies (35.9%) carried bacteria resistant to at least one antimicrobial, while 7 insects (5.9%) carried multidrug-resistant bacteria (MDR), which were all members of the family Enterobacteriaceae. Among 10 MDR bacteria (5%), 5 strains (2,5%) were positive by PCR for one or more of the following antibiotic resistance genes: aac(6')-Ib, blaTEM-1, blaCTX-M-15, blaKPC-2 and blaNDM-1. Analysis of variance (ANOVA) and cluster analysis compared the number of resistant isolates per collection point and showed that a single location was statistically different from the others with regard to resistance. Although there are still no criteria to determine the environmental contamination by resistant bacteria the fact that they have been isolated from flies is an indication of a disseminated contamination. As such, these insects may be useful in monitoring programs of antibiotic resistance in non-hospital environments, where they could function as sentinels.

Escherichia coli Capacity to Repopulate Microcosms Under Osmotic/U.V. Synergic Stress in Tropical Waters.

In both Brazilian and European regulations, the impact assessment of sewage discharges into coastal waters is based on microbiological analyses of fecal indicators such as Escherichia coli, frequently used in prevision hydrodynamic models. However, the decay rates of E. coli vary depending on environmental conditions, and analysis may lead to inaccurate conclusions. This study aimed to analyze the decay of culturable and viable (but not culturable) E. coli in outdoor conditions, by creating microcosms inoculated with pre-treated sewage. The microcosms were filled with 9.88 L of filtered water (0.22 µm membrane), 3.5% salt, 0.1-0.2% BHI, and 1% bacterial suspension obtained by reverse filtration. PMA-qPCR of E. coli uidA gene and Colilert measurements were applied to evaluate population counts after 2 h, 4 h, and 26 h. After nine hours of exposure to solar radiation, the viable cells decreased to 2.76% (interpolated value) of the initial population, and the cultivable fraction of the viable population accounted for 0.50%. In the dark period, the bacteria grew again, and viable cells reached 8.54%, while cultivable cells grew to 48.14% of initial population. This behavior is possibly due to the use of nutrients recycled from dead cells. Likewise, populations of E. coli in sewage outfalls remain viable in the sediments, where resuspension can renew blooming.

Correlation between hepatopulmonary syndrome and oxygen saturation pulse oximetry in cirrhotic patients.

OBJECTIVE: Hepatopulmonary Syndrome (HPS) is a complication of cirrhosis that worsens the disease's prognosis, pre and post liver transplant. The objective of this study is to analyze the prevalence of HPS in cirrhotic patients at our service and to correlate it with oxygen saturation (SatO2) using a pulse oximeter to evaluate if this is useful as a screening test for HPS. A prospective study was conducted in patients with hepatic cirrhosis conventionally selected from 2014 to 2016. All the patients underwent an echocardiogram with microbubbles and oxygen saturation measurement by pulse oximetry. Those with intrapulmonary shunt were submitted to arterial blood gas analysis. The relationship between oxygen saturation and HPS was assessed by the multivariate model of binary logistic regression. We analyzed 77 patients, and 23.3% (18 patients) had all criteria for HPS. The relationship between HPS and SatO2 did not show statistical significance, even after the variables were adjusted for sex, age, and smoking. Oxygen saturation alone was not able to detect HPS in the sample of cirrhotic patients. More accurate methods for screening and diagnosis of the syndrome should be used.

RESUMO A Síndrome Hepatopulmonar (SHP) é uma complicação da cirrose que piora o prognóstico da doença pré e pós-transplante hepático. O objetivo do trabalho é analisar a prevalência de SHP em pacientes cirróticos de nosso serviço e correlacioná-la com a saturação de oxigênio (SatO2) pelo oxímetro de pulso, e avaliar se este seria útil como um exame de triagem no diagnóstico de SHP. Foi realizado um estudo prospectivo em pacientes portadores de cirrose hepática no período de 2014 a 2016. Todos os pacientes foram submetidos a um ecocardiogama com microbolhas e a saturação de oxigênio pela oximetria de pulso. Aqueles com shunt intrapulmonar foram submetidos a gasometria arterial. A relação entre a saturação de oxigênio e SHP foi avaliada pelo modelo multivariado de regressão logística binário. Foram analisados 77 pacientes, destes 23,3% (18 pacientes) apresentaram todos os critérios para SHP. A relação entre a SHP com a SatO2 não obteve significância estatística, mesmo após as variáveis terem sido ajustadas pelo sexo, idade e tabagismo atual ou passado. A saturação de oxigênio, de forma isolada, não foi capaz de distinguir a SHP na amostra de pacientes cirróticos em nosso estudo. Deve-se utilizar métodos mais acurados para a triagem e diagnóstico dessa síndrome.

Separation of Escherichia coli from natural samples for identification of sources and microcosm inoculation.

Obtaining uncultured Escherichia coli from natural waters is an important step in the study of microbes in the environment, which are critical for bacterial decay and microbial source tracking. The quality of the samples used can influence the assays, because high contaminant concentrations, differing cell ages, and physiologic states can impair results. The proposed separation is based on a three-step filtration method applied to replicates of seven samples from a sewage plant affluent, collected in different periods. Aliquots of the leachate were inoculated into microcosms, aiming to observe the cultivability of the cells. The assay resulted in colimetry values ranging between 104 and 105 cells. In the leachate, averages of 1.05% of total coliforms and 1.10% of Escherichia coli were recovered from original samples. Although enduring unfavorable temperatures, salinities, and nutritional conditions, the inoculated microcosm populations grew approximately 310 times after 24 h. The final leachate contained cultivable cells in appropriate physiological states and quantities for inoculum in microcosm sets. The bacteria obtained from the leachate were also appropriate for surveys of microbial source tracking, because, in the developed procedure, organisms were separated from contaminants, while cell concentrations were sufficient for inocula.

Cervical Cytology of Samples with Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Trichomonas vaginalis, Mycoplasma hominis, and Neisseria gonorrhoeae Detected by Multiplex PCR.

INTRODUCTION: Despite increasing application of molecular diagnostic methods for the detection of sexually transmitted infections, the cytological findings in pap smears of patients with pathogens that can be identified only by PCR are not yet well described. The aim of this study was to describe the most common cytological features in cervical pap smears of patients with Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, Mycoplasma hominis, Ureaplasma urealyticum, and Ureaplasma parvum detected by multiplex PCR. METHODS: Cervical samples for conventional and liquid-based cytology and for multiplex PCR were collected from women ranging from 23 to 54 years old, who underwent routine screening at a gynecological Unit. RESULTS: Multiplex PCR was positive in 36.2% of the samples: Ureaplasma parvum 14.9%, Chlamydia trachomatis 10.6%, Trichomonas vaginalis 10.6%, Mycoplasma hominis 8.5%, Ureaplasma urealyticum 4.2%, Neisseria gonorrhoeae 2.1%, and Mycoplasma genitalium (0). Multiple pathogens were observed in 12.8% of samples. Microscopic cervicitis (≥10 polymorphonuclear leukocytes/epithelial cell) and normal (predominantly lactobacillary) microbiota were the most frequent findings in the samples in which the pathogens were detected alone or in multiple infections, except for samples with Trichomonas vaginalis in which the coccobacillary microbiota was the most common. In samples with microscopic cervicitis and normal microbiota, those with at least one pathogen identified by multiplex PCR were significantly more frequent than those with no pathogen, 66.6% versus 33.3%. CONCLUSION: Failure to identify an inflammatory agent in pap smear with intense neutrophil exudate may suggest the presence of Ureaplasma parvum, Ureaplasma urealyticum, Chlamydia trachomatis, or Trichomonas vaginalis. A remark on the intensity of inflammation should be made in the reports of cervical pap smears so that this cytological finding can be correlated with clinical and PCR results.

P16 as a marker of carcinoma in effusions and peritoneal washing.

BACKGROUND: Considering the potential of p16 as a marker for diagnosis, prognosis and therapeutic response, the aim of this study was to assess its presence, via immunocytochemistry, in metastatic carcinoma of different primary sites and histological types obtained from effusions and peritoneal washings. A total of 118 samples including 85 of metastatic carcinoma and 33 samples of benign effusion/peritoneal washing were prepared by the plasma/thromboplastin method. Immunocytochemistry reactions were performed on cell block sections using antibodies against p16, claudin-4, MOC-31, calretinin, HBME and CD68. RESULTS: P16 overexpression was observed in 88.23% of all carcinoma samples. All cervix adenocarcinoma samples showed p16 overexpression. Overexpression in adenocarcinomas of ovary, lung and breast was observed in 93.75, 93.10 and 75% of the samples, respectively. Overexpression was observed in all different histological types analyzed: small cell carcinoma (lung), squamous cell carcinoma (cervical) and urothelial carcinoma (bladder). The specificity of p16 for carcinoma detection was of 96.96%. CONCLUSION: Overexpression of p16 was observed in most metastatic carcinoma, from different primary sites and histological types, obtained from effusions and peritoneal washings. Due to its high frequency of overexpression in metastatic carcinoma, p16 may play a possible role in tumor progression and it may be considered as a complementary diagnostic marker depending on histological type and primary site of carcinoma.

RECOMMENDATIONS FOR INVASIVE PROCEDURES IN PATIENTS WITH DISEASES OF THE LIVER AND BILIARY TRACT: REPORT OF A JOINT MEETING OF THE BRAZILIAN SOCIETY OF HEPATOLOGY (SBH), BRAZILIAN SOCIETY OF DIGESTIVE ENDOSCOPY (SOBED) AND BRAZILIAN SOCIETY OF INTERVENTIONAL RADIOLOGY AND ENDOVASCULAR SURGERY (SOBRICE).

Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepato-logy (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.

Anti-EpCAM antibodies for detection of metastatic carcinoma in effusions and peritoneal wash.

Epithelial cell adhesion molecule (EpCAM) has been used as diagnostic/prognostic marker and therapeutic target. The aim of the present study was to compare immunoreactivity of antibodies against distinct epitopes in the ectodomain of EpCAM for detection of carcinoma from different primary sites and of different histological types in effusions and peritoneal wash. Two antibodies against epitopes in the EGF-like domain I (clones Moc-31 and Ber-EP4) and one antibody against the epitope in the cysteine-poor region (158210) of EpCAM were used (all commercially available). Independently of the clone used, EpCAM overexpression was observed in almost all samples when all the adenocarcinoma samples were analyzed together. By using Moc-31, EpCAM overexpression was observed in all samples of adenocarcinoma. Absence of EpCAM overexpression was observed in a few adenocarcinoma samples at some sites of tumor origin, including ovary, breast and stomach, when Ber-EP4 and 158210 were used. Regarding carcinomas aside from adenocarcinomas, histological types, such as squamous cell, urothelial and small cell carcinoma showed different degrees of EpCAM expression according to the antibody used. In squamous cell carcinoma, overexpression was observed only with the clone 158210. It was concluded that, overall, most samples of metastatic carcinoma from effusions showed overexpression of EpCAM. However, there are significant variations in its detection according to the primary site, histological type of the carcinoma and depending on the antibody used. Thus, the use of more than one type of anti-EpCAM antibody would increase the chance of its detection in metastatic carcinoma effusion.

Interferon-Beta Treatment Differentially Alters TLR2 and TLR4-Dependent Cytokine Production in Multiple Sclerosis Patients.

OBJECTIVE: Multiple sclerosis (MS) is a multifactorial chronic disease that affects the central nervous system (CNS). Toll-like receptors (TLRs) play a central role in cytokine production after pathogen- and danger-associated molecular patterns (PAMPs and DAMPs) and contribute to CNS damage in MS patients. Here, we evaluated the effects of interferon (IFN)-ß treatment in TLR2 and TLR4-dependent cytokine production and mRNA expression in whole-blood cell cultures from MS patients. METHODS: We evaluated cytokine production by ELISA from whole-blood cell culture supernatants and mRNA expression by real-time polymerase chain reaction in peripheral blood mononuclear cells (PBMCs). RESULTS: In patients treated with IFN-ß, tumor necrosis factor (TNF)-α production after exposure to TLR2 agonist (Pam3Cys) was lower than in healthy controls and untreated MS patients. However, IFN-ß treatment had no significant effect on TNF-α production after TLR4 agonist (LPS) stimulation. On the other hand, interleukin (IL)-10 production was increased in TLR4- but not in TLR2-stimulated whole-blood cell culture from MS patients under IFN-ß treatment when compared to the controls. No differences in TNF-α or IL-10 mRNA expression in PBMCs from healthy controls and untreated or treated MS patients were detected, although PBMCs from treated patients presented higher levels of IL-32γ mRNA than those from controls. CONCLUSIONS: Our data suggest that IFN-ß treatment alters the TLR-dependent immune response of PBMCs from MS patients. This may contribute to the beneficial effects of IFN-ß treatment.

An elderly man with gastric cancer, Saint's triad and Heyde's syndrome.

This case study describes a 71-year-old man with signet-ring cell gastric adenocarcinoma and malignant sigmoidal polyp; and typical features of Saint's triad and Heyde syndrome. He had digestive bleeding, two types of hernia, diverticulosis, arterial hypertension, malignant polyp, and antecedent of smoking, lung tuberculosis, and surgical correction of aortic valve stenosis. There is a hypothetical inverse relationship between herniosis and development of malignancy; however, the patient herein described presented gastric and sigmoidal cancers. Gastrointestinal malignancies are sometimes associated with paraneoplastic entities, isolated or manifested as syndromes, but neither Saint's triad or Heyde syndrome have been included. This patient persisted clinically stable during the preoperative period, but suddenly died; Trousseau's syndrome would be the most probable mechanism of sudden death in this setting. Case reports can stimulate further studies to get additional knowledge about unusual entities.

An elderly man with gastric cancer, Saint's triad and Heyde's syndrome / Un anciano con cáncer gástrico, tríada de Saint y síndrome de Heyde

This case study describes a 71-year-old man with signet-ring cell gastric adenocarcinoma and malignant sigmoidal polyp; and typical features of Saint's triad and Heyde syndrome. He had digestive bleeding, two types of hernia, diverticulosis, arterial hypertension, malignant polyp, and antecedent of smoking, lung tuberculosis, and surgical correction of aortic valve stenosis. There is a hypothetical inverse relationship between herniosis and development of malignancy; however, the patient herein described presented gastric and sigmoidal cancers. Gastrointestinal malignancies are sometimes associated with paraneoplastic entities, isolated or manifested as syndromes, but neither Saint's triad or Heyde syndrome have been included. This patient persisted clinically stable during the preoperative period, but suddenly died; Trousseau's syndrome would be the most probable mechanism of sudden death in this setting. Case reports can stimulate further studies to get additional knowledge about unusual entities.

Este estudio de caso describe un hombre de 71 años de edad, con adenocarcinoma gástrico con células en anillo de sello y un pólipo maligno sigmoideo; y características típicas de la tríada de Saint y del síndrome de Heyde. Tuvo una hemorragia digestiva, dos tipos de hernias, divertículos, hipertensión arterial, y pólipo maligno; con antecedente de tabaquismo, tuberculosis pulmonar, y corrección quirúrgica de estenosis de la válvula aórtica. Hay una hipotética relación inversa entre hernioses y el desarrollo de malignidades; sin embargo, el paciente que se describe en el presente documento presentó cánceres gástrico y sigmoideo. Neoplasias gastrointestinales se asocian a veces con entidades para neoplásicas aisladas o manifiestan síndromes, pero ni la tríada de Saint ni el síndrome de Heyde se ha incluido. Este paciente persistió clínicamente estable durante el período preoperatorio, pero de repente murió; síndrome de Trousseau sería el mecanismo más probable de muerte súbita en esta situación. Los informes de casos pueden estimular más estudios para obtener un conocimiento adicional sobre esas entidades inusuales.
