RESUMO

Proton therapy has gained interest in recent years due to its excellent clinical outcomes. However, the lack of accurate biological data, especially in the Bragg peak region of clinical beams, makes it difficult to implement biophysically optimized treatment plans in clinical practice. In this context, low energy proton accelerator facilities provide the perfect environment to collect good radiobiological data, as they can produce high LET beams with narrow energy distributions. This study presents the radiobiology beam line that has been designed at the 18 MeV proton cyclotron facility at the National Centre of Accelerators (CNA, Seville, Spain), to perform irradiations of mono-layer cell cultures. To ensure that all the cells receive the same dose with a suitable dose rate, low beam intensities and broad and homogeneous beam profiles are necessary. To do so, at the CNA an unfocused beam has been used, broadened with a 500 µm thick aluminium scattering foil. Homogeneous dose profiles, with deviations lower than 10% have been obtained over a circular surface of 35 mm diameter for an incident average energy of 12.8 MeV. Further, a Monte Carlo simulation of the beam line has been developed with Geant4, and benchmarked towards experimental measurements, with differences generally below 1%. Once validated, the code has been used, together with an ionization chamber, for dosimetry studies, to characterize the beam and monitor the dose. Finally, cultures of Human Bone Osteosarcoma cells (U2OS) have been successfully irradiated at the radiobiology beam line, investigating the effects of radiation in terms of DNA damage induction.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is currently the most common cause of liver disease in children and adolescents in the United States of America (USA) and probably in the entire western hemisphere, due to the increase in the prevalence of overweight and obesity. Steatosis can progress to inflammation, fibrosis and even cirrhosis, which increases the morbidity and mortality associated to liver disease. In every overweight and obese child a thorough analysis should be performed including liver function tests and liver ultrasound, in order to establish a timely diagnosis. The liver biopsy is the most specific study to rule out other potentially treatable entities. It is necessary to count on non-invasive methods to detect children with NAFLD and identify those in risk of progression. Biomarkers related to inflammation, oxidative stress, apoptosis and fibrosis have been reported. The main goal of the treatment is to modify the life style, starting with a healthy diet and an increase of physical activity. Regarding pharmacological treatment, there is evidence of histological improvement with vitamin E use, as opposed to metformin, but more conclusive studies regarding this subject are needed.


La enfermedad por hígado graso no alcohólico (EHGNA) es actualmente la primera causa de enfermedad hepática en niños y adolescentes en Estados Unidos de América (EUA) y probablemente en el mundo occidental, dado el incremento en la prevalencia de sobrepeso y obesidad. La esteatosis hepática puede progresar a inflamación, fibrosis y cirrosis que incrementa la morbilidad y mortalidad asociadas a enfermedad hepática. En todo niño con sobrepeso y obesidad se requiere un escrutinio mediante determinación de transaminasas y ultrasonido hepático para un diagnóstico oportuno. La biopsia hepática es el estudio con mayor discriminación para descartar otras entidades potencialmente tratables. Es necesario contar con métodos no invasivos para detectar niños con EHGNA e identificar a aquellos con riesgo de progresión. Se han reportado biomarcadores de inflamación, estrés oxidativo, apoptosis y fibrosis. El tratamiento tiene como objetivo la modificación del estilo de vida con dieta saludable y mayor actividad física. Respecto a tratamiento farmacológico, hay evidencias de mejoría histológica con vitamina E, y no se presenta ningún beneficio con Metformin, pero se requieren más estudios con resultados más sólidos.

RESUMO

OBJECTIVE: Streptococcus oralis is an early coloniser of the oral cavity that contributes to dental plaque formation. Many different genotypes can coexist in the same individual and cause opportunistic infections such as bacterial endocarditis. However, little is known about virulence factors involved in those processes. The aim was to analyze the evolving growth of S. oralis colony/biofilm to find out potentially pathogenic features. DESIGN: Thirty-three S. oralis isolates were analyzed for: (1) biofilm production, by spectrophotometric microtiter plate assay; (2) colonial internal architecture, by histological methods and light and electron microscopy; (3) agar invasion, by a new colony-biofilm assay. RESULTS: S. oralis colonies showed two different growth patterns: (1) fast growth rate without invasion or minimally invasive; (2) slow growth rate, but high invasion ability. 12.1% of strains were biofilm non-producers and 24.2% not invasive, compared to 51.5% biofilm high-producers and 39.4% very invasive. Both phenotypic characteristics tended to be mutually exclusive. However, a limited number of strains (15%) co-expressed these features at the highest level. CONCLUSIONS: Morphological plasticity of S. oralis highlighted in this study may have important ecological and clinical implications. Coexistence of strains with different growth patterns could produce a synergic effect in the formation and development of subgingival dental plaque. Moreover, invasiveness might regulate dissemination and colonisation mechanisms. Simultaneous co-expression of high-invasive and high-biofilm phenotypes gives a fitness advantage during colonisation and may confer higher pathogenic potential.

RESUMO

INTRODUCTION: Extrahepatic portal vein obstruction is an important cause of portal hypertension among children. The etiology is heterogeneous and there are few evidences related to the optimal treatment. AIM AND METHODS: To establish guidelines for the diagnosis and treatment of EHPVO in children, a group of gastroenterologists and pediatric surgery experts reviewed and analyzed data reported in the literature and issued evidence-based recommendations. RESULTS: Pediatric EHPVO is idiopathic in most of the cases. Digestive hemorrhage and/or hypersplenism are the main symptoms. Doppler ultrasound is a non-invasive technique with a high degree of accuracy for the diagnosis. Morbidity is related to variceal bleeding, recurrent thrombosis, portal biliopathy and hypersplenism. Endoscopic therapy is effective in controlling acute variceal hemorrhage and it seems that vasoactive drug therapy can be helpful. For primary prophylaxis of variceal bleeding, there are insufficient data for the use of beta blockers or endoscopic therapy. For secondary prophylaxis, sclerotherapy or variceal band ligation is effective; there is scare evidence to recommend beta-blockers. Surgery shunt is indicated in children with variceal bleeding who fail endoscopic therapy and for symptomatic hypersplenism; spleno-renal or meso-ilio-cava shunting is the alternative when Mesorex bypass is not feasible due to anatomic problems or in centers with no experience. CONCLUSIONS: Prospective control studies are required for a better knowledge of the natural history of EHPVO, etiology identification including prothrombotic states, efficacy of beta-blockers and comparison with endoscopic therapy on primary and secondary prophylaxis.

RESUMO

INTRODUCTION: Identifying liver fibrosis is important to evaluate the severity of liver damage and to establish a prognosis. Utility of non-invasive markers of liver fibrosis has been proved in adults but there are few reports in children. The aim of this study was to evaluate Fibrotest® score and APRI suitability to identify children with liver fibrosis. MATERIAL AND METHODS: 68 children with chronic liver disease requiring liver biopsy were prospectively included from three 3rd-level pediatric hospitals. The same pathologist evaluated all liver biopsies; fibrosis degree was determined by METAVIR score. Serum samples were obtained to determine Fibrotest® and APRI. AUROC were used to determine cut-off and differentiate between advanced fibrosis (METAVIR F3, F4) and no fibrosis (F0). RESULTS: 68 biopsies were evaluated; METAVIR > F3 was identified in 26 (38%). Non invasive liver fibrosis markers to differentiate between advanced and no fibrosis were: Fibrotest® AUROC = 0.90 (95% CI 0.77-1.00) (cut-off value 0.35) sensitivity 88.00% (95% CI 68-96) and specificity 80% (95% CI 29-98); and for APRI AUROC = 0.97 (95% CI 0.92-1.00) (cut-off value 0.82), sensitivity 88% (95% CI 68-96) and specificity = 100% (95% CI 46-100). CONCLUSION: These results suggest the utility of Fibrotest® and APRI to identify advanced fibrosis; they can be recommended to select patients for liver biopsy and during patient follow-up.

RESUMO

MS-based quantitative proteomics plays an increasingly important role in biological and medical research and the development of these techniques remains one of the most important challenges in mass spectrometry. Numerous stable isotope labeling approaches have been proposed. However, and particularly in the case of (18)O-labeling, a standard protocol of general applicability is still lacking, and statistical issues associated to these methods remain to be investigated. In this work we present an improved high-throughput quantitative proteomics method based on whole proteome concentration by SDS-PAGE, optimized in-gel digestion, peptide (18)O-labeling, and separation by off-gel isoelectric focusing followed by liquid chromatography-LIT-MS. We demonstrate that the off-gel technique is fully compatible with (18)O peptide labeling in any pH range. A recently developed statistical model indicated that partial digestions and methionine oxidation do not alter protein quantification and that variances at the scan, peptide, and protein levels are stable and reproducible in a variety of proteomes of different origin. We have also analyzed the dynamic range of quantification and demonstrated the practical utility of the method by detecting expression changes in a model of activation of Jurkat T-cells. Our protocol provides a general approach to perform quantitative proteomics by (18)O-labeling in high-throughput studies, with the added value that it has a validated statistical model for the null hypothesis. To the best of our knowledge, this is the first report where a general protocol for stable isotope labeling is tested in practice using a collection of samples and analyzed at this degree of statistical detail.

RESUMO

Objetivo: caracterizar desde el punto de vista clínico y parasitológico a un grupo de pacientes que en la red de salud de Ciudad de La Habana habían sido tratados, o serían tratados, por padecer de manifestaciones cutáneas atribuidas a giardiasis. Métodos: previo acuerdo con los médicos de asistencia correspondientes, 114 individuos que habían sido tratados, o serían tratados, por padecer de lesiones dermatológicas atribuidas a giardiasis fueron remitidos al Instituto de Medicina Tropical Pedro Kourí (IPK). A su arribo, a cada paciente se le realizó una caracterización de sus manifestaciones clínicas por parte de los médicos que formaban parte del equipo de investigadores. A cada individuo se le solicitó muestras seriadas de heces, a las que se le practicaron exámenes cropológicos mediante los procedimientos de frotis directo simple y de concentración de Ritchie. En aquellos casos en que la observación microscópica de las muestras de heces no permitió confirmar la infección por Giardia lamblia, se realizó drenaje biliar para la búsqueda microscópica de las giardias en el líquido duodenal correspondiente. A los pacientes en cuyas heces o líquido duodenal se detectó la presencia de G. lamblia, se les indicó tratamiento antigiardiásico y se orientaron las medidas higiénico-sanitarias necesarias para evitar la reinfección. Después de 3 meses de concluido el tratamiento antiparasitario, se repitieron los estudios antes descritos. Resultados: se demostró que en Ciudad de La Habana las manifestaciones cutáneas de la giardiasis constituyen un problema de salud sobredimensionado. Se confirmó, además, que son las lesiones urticarianas las manifestaciones dermatológicas más frecuentes asociadas a giardiasis. Conclusiones: demostrada la sobredimensión de la giardiasis como causa de lesiones dermatológicas, se hace necesario incursionar en la exploración de los conocimientos, percepciones...


Objective: to make a clinical and parasitological characterization of a group of patients, who had been or would be treated in the healthcare facilities of the City of Havana, due to their cutaneous manifestations attributed to giardiasis. Methods: after the consent of their primary care physicians, 114 subjects, who had been or would be treated because of their giardiasis-attributed skin lesions, were referred to Pedro Kourí Institute of Tropical Medicine. On their arrival, the research team physicians characterized each patient according to their clinical manifestations. They were asked to collect their feces for serial sampling, which were subjected to chropological tests through direct simple smears and Ritchie´s concentration procedures. In those cases where microscopic observation of samples did not allow confirming Giardia lamblia infection, biliary drainage was performed to look for giardias in the corresponding duodenal fluid. The patients whose feces or duodenal fluid showed G.lamblia were instructed to follow an anti-giardiasis treatment and the necessary hygienic-sanitary measures to prevent re-infection. Three months after concluding the parasiticidal treatment, the above-mentioned tests were repeated. Results: it was proved that the cutaneous manifestations of giardiasis in the City of Havana are an overdimensioned health problem. It was also confirmed that urticaria is the most frequent giardiasis-associated dermatological manifestation. Conclusions: once the overdimension of giardiasis as a cause of skin lesions is proven, it is necessary to explore the knowledge, perceptions and practice of physicians in charge of diagnosis, treatment and control of this disease.

RESUMO

El desorden linfoproliferativo en el paciente transplantado es una entidad caracterizada por una proliferación del linfocito B infectado por el virus de Epstein Barr (EBV), que provoca manifestaciones extracutáneas y cutáneas. La forma cutánea de presentación es infrecuente. Presentamos dos pacientes transplantados, renal y cardiopulmonar, que presentaron nódulos en la pierna derecha y en el tronco. El estudio histopatológico reveló la presencia de un infiltrado de blastos linfoides de estirpe B. El tratamiento se basó en el descenso de la inmunosupresión, además de radioterapia y quimioterapia. La evolución del cuadro fue favorable en ambos pacientes (AU)

RESUMO

OBJECTIVE: To compare clinical and bacteriologic efficacy of two therapeutic trials to eradicate Helicobacter pylori (H. pylori) in two series of pediatric patients with recurrent abdominal pain (RAP). MATERIALS AND METHODS: n = 36 children with RAP-associated H. pylori infection. Age 9.8 +/- 3.1 years, 19 boys and 17 girls. Clinical and bacteriologic efficacy of two therapeutic trials was compared: Group A (1996-1997), n = 9, amoxicillin, bismuth subsalicilate, and metronidazol, and group B (1991-1993), n = 27, omeprazol, amoxicillin, and clarithromycin. Initially and post-treatment, H. pylori evaluation was carried out with upper endoscopy and gastric biopsies. For statistics, we used Student t test, chi2, Fisher test, and Kruskal-Wallis analysis of variance (alpha = 0.05). RESULTS: We found that 33/36 cases had gastritis at endoscopy, two with duodenal ulcer; nodular gastritis was observed in more than one half of total cases. All cases fulfilled histologic criteria of gastritis according to Sydney Score. In group A eradication was achieved in 28.6%, while in group B eradication rose to 77.8% (p < 0.05). In group A, 8/9 and in group B 15/27 persisted with RAP (p = 0.113). CONCLUSIONS: High frequency of abnormal and histologic findings was observed in the series presented on children with RAP and H. pylori. Eradication efficacy in the omeprazol/amoxicillin/clarithromycin group was higher when compared with bismuth subsalicilate/amoxicillin/metronidazol trial. This efficacy is comparable to pediatric series treated with the same therapeutic trial.

The movement makes that the animals satisfy their own necessities and for the men he/she makes possible to adapt for themselves to the life, for what was carried out a descriptive, retrospective and traverse work, with the objective of demonstrating the positive influence of the physical exercises in the patient's health, in the policlínico Armando García in the understood period of January-June of 2000. The universe and the sample were constituted by the entirety of the grandparents belonging to a circle of the Clinic of the Doctor of the Family #16 that it threw a figure of 25 patients; the method of gathering of the information was formed by the ambulatory clinical histories of the patients and the interrogation to these and among the studied variables they are: age, sex, illnesses, the patients' health before and after carrying out physical exercises. Among the main conclusions we find that according to the age and the sex of the members, we observe that the biggest percentage belongs to the feminine sex and they are between the 60 and the 69 years of age, the patients with different illnesses stay compensated with the systematic practice of the physical exercise, the illness that more it prevails it is the arterial hypertension, the 100 (percent) it maintained the levels of normal glicemia after the physical exercises, the entirety of the patient hipertensos normalized the arterial tension, the same as the patients that suffer of artrosis that were compensated. The independent infirmary actions were those that stood out, achieving that the biggest number of patients presented positive changes in its evolution(AU)

RESUMO

A cuatro pacientes se les realizó un injerto libre de piel total para cubrir el defecto provocado por la extirpación de distintas lesiones de piel, tres de ellos con patología tumoral maligna y uno con patología névica. La selección del área dadora se realizó teniendo en cuenta color, consistencia, espesor y cualidades sebáceas y pilosas de la piel del área receptora. Un sólo paciente presentó una necrosis parcial epidérmica del injerto durante el postoperatorio. En todos los casos se obtuvo la cicatrización del injerto con buenos resultados. Destacamos el injerto libre de piel total como una opción quirúrgica que puede ser utilizada por el dermatólogo cirujano cuando no se puede realizar el cierre simple directo de una herida (AU)
