    Hernia de hiato: a propósito de un caso.

    Get PDF
    La hernia de hiato es un defecto anatómico frecuente en nuestro medio que se produce en el diafragma debido a factores como la debilidad de éste por el paso del tiempo, traumatismos o alteraciones congénitas. Esta alteración supone un ascenso del estómago a la cavidad torácica, lo cual implica la aparición en algunos casos de síntomas de reflujo gastroesófagico y complicaciones. El diafragma tiene su origen en el septo transverso, las membranas pleuroperitoneales, el mesenterio dorsal del esófago y el crecimiento muscular de los somitas en los segmentos cervicales 3 a 5 de la pared corporal, mientras que el esófago y el estómago derivan del intestino primitivo anterior. La mejor prueba de imagen para su diagnóstico es el esofagograma de bario, mientras que el tratamiento es en un principio higiénico-dietético y médico, si bien derivará en cirugía en caso de que no se controlen los síntomas. Así, en este trabajo se pretende hacer una revisión en profundidad de la etiología de la hernia de hiato, su clínica, su diagnóstico y su tratamiento acompañándolo de un caso clínico.<br /

A complete ocular and systemic examination, including OCTA imaging tests and bloods, was performed. OCTA parameters included vessel density (VD), perfusion density (PD), foveal avascular zone area (FAZa), perimeter (FAZp) and circularity (FAZc) in the superficial vascular plexus, and DKD categories were defined according to glomerular filtration rate (GFR), albumin-creatinine ratio (ACR) and KDIGO prognosis risk classifications. A total of 425 individuals (1 eye/1 patient) were included. Reduced VD and FAZc were associated with greater categories of GFR (p = 0.002, p = 0.04), ACR (p = 0.003, p = 0.005) and KDIGO risk prognosis classifications (p = 0.002, p = 0.005). FAZc was significantly reduced in greater KDIGO prognosis risk categories (low risk vs. moderate risk, 0.65 ± 0.09 vs. 0.60 ± 0.07, p < 0.05). VD and FAZc presented the best diagnostic performance in ROCs. In conclusion, OCTA parameters, such as VD and FAZc, are able to detect different GFR, ACR, and KDIGO categories in T1DM patients and controls in a non-invasive, objective quantitative way. FAZc is able to discriminate within T1DM patients those with greater DKD categories and greater risk of DKD progression.This research was funded by Fundació La Marató de TV3, La Marató 2015, Diabetis i Obesitat (grant number 201633.10) and Instituto de Salud Carlos III, (through the project PI18/00518, co-funded by European Regional Development Fund “Investing in your future”).

    Presentamos el caso de un varón de 16 años que consultó en Urgencias por dolor abdominal brusco de varias horas de evolución asociando pérdida de conciencia. En días previos había presentado odinofagia y fiebre alta. En las pruebas complementarias destacaba la presencia de leucocitosis de predominio linfocítico, mientras que tanto la ecografía como la tomografía computarizada desvelaron una rotura esplénica con hemoperitoneo, por lo que se llevó a cabo cirugía urgente (esplenectomía), que cursó sin incidencias. La rotura esplénica supone una situación de emergencia vital en el paciente joven, por lo que una buena anamnesis y exploración física es esencial para así evitar errores en la práctica clínica que puedan conllevar un desenlace potencialmente fatal.We present the case of a 16-year-old male who asked in an emergency department for sudden abdominal pain since many hours and loss of consciousness. Few days before, he had odynophagia and high fever. Leucocytosis with lymphocytosis predominance in analysis and splenic rupture with hemoperitoneum in echography and computerized tomography was shown. The treatment consisted in urgent surgery (splenectomy), which was uneventful. Splenic rupture is an emergency in young patients, so it is essential to do a good anamnesis and physical exploration to avoid mistakes with a potentially fatal outcome

    Association of urinary activity of MMP-9 with renal impairment in Mexican patients with type 2 diabetes mellitus

    Background Diabetic kidney disease is the most common cause of chronic kidney disease (CKD). An early event in diabetic kidney disease is alteration of the glomerular basement membrane and the mesangial expansion. Matrix metalloproteinases (MMP) are a family of endopeptidases responsible for controlling the pathophysiological remodeling of tissues, including renal tissues. MMP-9 in human urine has been proposed as a marker of diabetic nephropathy and urinary tract infections (UTI). Methods A cross-sectional study was conducted in type 2 diabetes mellitus (T2DM) patients who receive first level medical attention in Mexico. We used ELISA to measure MMP-9 levels in the urine of subjects with T2DM ≥ 18 years of age, who fulfilled the clinical requirements for calculation of glomerular filtration rate (GFR), according to the K/DOQI guide, in an attempt to identify whether MMP-9 levels in T2DM differ in patients with and without renal impairment. Univariate and multivariable analyses were performed in order to identify the association between MMP-9 and renal impairment. Results Included in the study were 34 (45%) subjects with renal impairment and 42 (55%) without. In the group with renal impairment, 10 subjects corresponded to stages 1–2 and 24 subjects corresponded to stage 3, according to their values of GFR and urinary albumin, following that proposed by the K/DOQI. No differences were found relating to sex, age, having or not having a partner, education, being able to read and write a message and duration of T2DM. Moreover, no differences were found between the groups in terms of weight, height, body mass index, waist size in general and frequency of UTI. In contrast, serum creatinine and urinary albumin were higher in the group with renal impairment, while GFR was greater in the group without renal impairment. Levels of MMP-9 were greater in women compared to men. Through univariate analysis in the general population, the presence of MMP-9 and that of its percentile 90 (P90) P90 were associated with the renal impairment group; however, in patients without UTI, only the presence of MMP-9 was associated with the renal impairment group, and no association was found with its P90. Multivariate analysis revealed an association between MMP-9 and its P90 with renal impairment. Discussion It is necessary to validate sensitive and non-invasive biological markers of CKD. We demonstrate that the presence and P90 of urinary MMP-9 are associated with renal impairment in Mexican patients with T2DM. While high levels of MMP-9 were associated to females and UTI, the presence of UTI was not associated with the incidence of renal impairment

    RB mutation and RAS overexpression induce resistance to NK cell-mediated cytotoxicity in glioma cells

    Several theories aim to explain the malignant transformation of cells, including the mutation of tumor suppressors and proto-oncogenes. Deletion of Rb (a tumor suppressor), overexpression of mutated Ras (a proto-oncogene), or both, are sufficient for in vitro gliomagenesis, and these genetic traits are associated with their proliferative capacity. An emerging hallmark of cancer is the ability of tumor cells to evade the immune system. Whether specific mutations are related with this, remains to be analyzed. To address this issue, three transformed glioma cell lines were obtained (Rb(-/-), Ras(V12), and Rb(-/-)/Ras(V12)) by in vitro retroviral transformation of astrocytes, as previously reported. In addition, Ras(V12) and Rb(-/-)/Ras(V12) transformed cells were injected into SCID mice and after tumor growth two stable glioma cell lines were derived. All these cells were characterized in terms of Rb and Ras gene expression, morphology, proliferative capacity, expression of MHC I, Rae1delta, and Rae1alphabetagammadeltaepsilon, mult1, H60a, H60b, H60c, as ligands for NK cell receptors, and their susceptibility to NK cell-mediated cytotoxicity. Our results show that transformation of astrocytes (Rb loss, Ras overexpression, or both) induced phenotypical and functional changes associated with resistance to NK cell-mediated cytotoxicity. Moreover, the transfer of cell lines of transformed astrocytes into SCID mice increased resistance to NK cell-mediated cytotoxicity, thus suggesting that specific changes in a tumor suppressor (Rb) and a proto-oncogene (Ras) are enough to confer resistance to NK cell-mediated cytotoxicity in glioma cells and therefore provide some insight into the ability of tumor cells to evade immune responses.Xunta de GaliciaComisión EuropeaInstituto de Salud Carlos IIIConsejo Nacional de Ciencia y Tecnologia (CONACyT)Consejo Nacional de Ciencia y Tecnologia (CONACyT)FOSSISXunta de Galicia/PXIB208091PRISCIII/CB158340ISCIII/CB180851FOSSIS/18236

    The authors are indebted with all participants, without whom this work would not have been possible. We are grateful to Ana Yara Postigo-Fuentes for her assistance with the English language. This paper is part of the PhD thesis developed by A. Lara-Ramos in the Official Doctoral Programme in Clinical Medicine and Public Health of the University of Granada.Aim: To explore endometriosis-related fatigue (ERF), health-related fitness, sleep quality, and health-related quality of life (HRQoL) in women with endometriosis in comparison with matched controls. Methods: Twenty-five affected women and twenty-five age and height-matched women without endometriosis were included. ERF was assessed through the Piper Fatigue Scale; health-related fitness was assessed through the Schöber, flamingo, and 6-min walking tests and dynamometry; and body composition was assessed through impedanciometry. Self-perceived physical fitness, sleep quality, and HRQoL were assessed through the International Fitness Scale, the Pittsburgh Sleep Quality Index, and the 12-item Short Form Health Survey, respectively. Results: Affected women exhibited higher levels of ERF than controls, increased fat mass, and physical deconditioning (reduced back strength, lumbar flexibility, body balance, and functional capacity, p-values < 0.050). Moreover, cases also had poorer perceived physical fitness, sleep quality, and HRQoL (p-value < 0.050). Finally, we observed deteriorated health-related fitness, sleep quality, and HRQoL in those women with endometriosis with higher levels of ERF. Conclusions: This study constitutes the first evidence that women with endometriosis describe a generalized physical deconditioning, even more pronounced in affected women with higher levels of ERF. Further studies assessing the efficacy of rehabilitation interventions to face these physical impairments in women with endometriosis are warranted.Health Institute Carlos III (ISCIII)-FEDER PI17/01743PAIDI group CTS-206University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES)Junta de AndaluciaConsejeria de Conocimiento, Investigacion y UniversidadesEuropean Union (EU) SOMM17/6107/UG
