RESUMO

The deficiency of CITRIN, the liver mitochondrial aspartate-glutamate carrier (AGC), is the cause of four human clinical phenotypes, neonatal intrahepatic cholestasis caused by CITRIN deficiency (NICCD), silent period, failure to thrive and dyslipidemia caused by CITRIN deficiency (FTTDCD), and citrullinemia type II (CTLN2). Clinical symptoms can be traced back to disruption of the malate-aspartate shuttle due to the lack of citrin. A potential therapy for this condition is the expression of aralar, the AGC present in brain, to replace citrin. To explore this possibility we have first verified that the NADH/NAD+ ratio increases in hepatocytes from citrin(-/-) mice, and then found that exogenous aralar expression reversed the increase in NADH/NAD+ observed in these cells. Liver mitochondria from citrin (-/-) mice expressing liver specific transgenic aralar had a small (~ 4-6 nmoles x mg prot-1 x min-1) but consistent increase in malate aspartate shuttle (MAS) activity over that of citrin(-/-) mice. These results support the functional replacement between AGCs in the liver. To explore the significance of AGC replacement in human therapy we studied the relative levels of citrin and aralar in mouse and human liver through absolute quantification proteomics. We report that mouse liver has relatively high aralar levels (citrin/aralar molar ratio of 7.8), whereas human liver is virtually devoid of aralar (CITRIN/ARALAR ratio of 397). This large difference in endogenous aralar levels partly explains the high residual MAS activity in liver of citrin(-/-) mice and why they fail to recapitulate the human disease, but supports the benefit of increasing aralar expression to improve the redox balance capacity of human liver, as an effective therapy for CITRIN deficiency.

RESUMO

While the signaling pathways and transcription factors involved in the differentiation of thyroid follicular cells, both in embryonic and adult life, are increasingly well understood, the underlying mechanisms and potential crosstalk between the thyroid transcription factors Nkx2.1, Foxe1 and Pax8 and inductive signals remain unclear. Here, we focused on the transcription factor Sox9, which is expressed in Nkx2.1-positive embryonic thyroid precursor cells and is maintained from embryonic development to adulthood, but its function and control are unknown. We show that two of the main signals regulating thyroid differentiation, TSH and TGFß, modulate Sox9 expression. Specifically, TSH stimulates the cAMP/PKA pathway to transcriptionally upregulate Sox9 mRNA and protein expression, a mechanism that is mediated by the binding of CREB to a CRE site within the Sox9 promoter. Contrastingly, TGFß signals through Smad proteins to inhibit TSH-induced Sox9 transcription. Our data also reveal that Sox9 transcription is regulated by the thyroid transcription factors, particularly Pax8. Interestingly, Sox9 significantly increased the transcriptional activation of Pax8 and Foxe1 promoters and, consequently, their expression, but had no effect on Nkx2.1. Our study establishes the involvement of Sox9 in thyroid follicular cell differentiation and broadens our understanding of transcription factor regulation of thyroid function.

RESUMO

INTRODUCCIÓN: El autotrasplante es una opción predecible para sustituir dientes no restaurables. El presente caso clínico describe el autotrasplante de un tercer molar inferior (3.8) en lugar de un segundo molar inferior (3.7).Caso clínico: Paciente varón de 22 años de edad que acude a una revisión general. A la exploración radiográfica, se observa reabsorción radicular del 3.7, producida por el 3.8 incluido. Se valoró el caso mediante un CBCT confirmando la inviabilidad del 3.7 y una correcta anatomía para la sustitución del 3.8. Después de valorar junto al paciente, las diferentes opciones de tratamiento posibles, se decide realizar el autotrasplante del diente 3.8, en el lugar del 3.7. Se realizó la exodoncia de ambos dientes, realizando el tratamiento de conductos extraoralmente del diente donante, bajo magnificación, y en un tiempo inferior a 20 minutos. Posteriormente se coloca una ferulización semirrígida a los dientes ad-yacentes durante 2 meses. Después del tratamiento quirúrgico/endodóntico, en el control a los 6 meses debido a la buena evo-lución clínica y la ausencia de sintomatología se realiza el trata-miento rehabilitador del diente autotrasplantado. CONCLUSIÓN: Las ventajas del autotrasplante quedan demostradas con los altos porcentajes de éxito que se obtienen al elegir esta opción de tratamiento. Es fundamental el uso del CBCT, tanto para la planificación, como para los posteriores controles radiográficos


INTRODUCTION: Autotransplantation is a predictable option to replace non restaurable teeth. This clinical case describes the autotransplantation of a lower third molar instead of a lower second molar. Clinical case: A 22 years-old male patient came to the clinic. On radiographic examination, it was observed root resorption of the lower second molar (3.7), produced by an included lower third molar (3.8). After checking with the patient all possible treatments, we decided to perform an autotransplant of tooth 3.8, instead of 3.7. Extraction of both teeth was necessary, performing the extraoral root canal treatment of the donor tooth, under magnification, and in less than 20 minutes. After that, a semi-rigid splint was placed to the adjacent teeth for 2 months. After the surgical / endodontic treatment, in the 6-month follow-up due to the good clinical evolution and the absence of symptoms, autotransplanted molar prosthetic rehabilitation treatment takes place. CONCLUSION: The advantages of autotransplantation are demonstrated by the high success rates that we obtain when choosing this treatment option. The use of CBCT is essential both for planning and for subsequent radiographic controls

RESUMO

INTRODUCCIÓN: El primer molar superior se caracteriza por tener 3 raíces y cuatro conductos radiculares. La presencia de cuatro raíces es un hallazgo inusual, pocas veces reportado en la literatura. CASO CLÍNICO: Acude a la consulta un paciente caucásico con pulpititis irreversible del 2.6. Se decide iniciar el trata-miento de conductos, pero dada la diferente morfología radicular visible radiográficamente, se realiza una CBCT previa. En el corte axial, se aprecian 4 raíces, con ápices totalmente independientes. Además, la raíz mesiovestibular presenta un único conducto y forma redondeada. Con la ayuda del microscopio se realiza una apertura inusual y se localizan los cuatro conductos. Finalizadas la instrumentación, irrigación y obturación, se recubre el acceso cameral con composite, para la posterior realización de una incrustación, capaz de sellar la caries cervical y restaurar los puntos de contacto. En el control 2 años posterior, el paciente está totalmente asintomático y la restauración demuestra su funcionalidad y estética. CONCLUSIÓN: Las anomalías anatómicas pueden presentar-se en cualquier diente. Encontrar un primer molar superior con más de tres raíces es un hallazgo muy extraño, pero gracias a la ayuda de la radiología tridimensional, se pudo visualizar y tratar de forma adecuada. Ante cualquier imagen radiográfica donde no se pueda apreciar con claridad la anatomía dental a tratar, debemos realizar varias proyecciones radiográficas o una CBCT para poder conocer la morfología real a la que nos enfrentamos


INTRODUCTION: The upper first molar is characterized by having three roots and four root canals. The presence of four roots is an unusual finding, rarely reported in the literature. CLINICA CASE: A caucasian patient with irreversible pulpititis of 2.6 comes to the dental clinic. It was decided to start the root canal treatment, but due to the different root morphology visible radiographically, a previous CBCT was performed. In the axial section, 4 roots are seen, with completely independent apexes. Furthermore, the mesiovestibular root has a single canal and a rounded shape. With the help of the microscope, an unusual opening is made and the four canals are located. After the instrumentation, irrigation and obturation are completed, the cameral access is covered with composite, for the subsequent inlay, capable of sealing cervical caries and restoring the contact points. In the control 2 years later, the patient is completely asymptomatic and the restoration demonstrates its functionality and aesthetics. CONCLUSIONS: Anatomic anomalies occur in any tooth. Finding an upper first molar with more than three roots is a very strange finding, but thanks to the help of three-dimensional radiology, it was able to be properly visualized and treated. Before any radiographic image where the dental anatomy to be treated cannot be clearly seen, we must carry out several radiographic projections or a CBCT to be able to know the real morphology that we are facing

RESUMO

Introducción: La metamorfosis cálcica se presenta comúnmente tras lesiones traumáticas y se caracteriza por presentar depósitos de tejido duro dentro del espacio pulpar, obliterando parcial o totalmente la cámara pulpar y/o el conducto radicular. Este proceso suele provocar un cambio de coloración de la corona clínica haciéndola más oscura y opaca. Caso clínico: Paciente mujer de 40 años acude a la consulta motivada por una preocupación estética debido al oscurecimiento del diente 21. Se proponen varias opciones de tratamiento, hasta que finalmente se opta por el tratamiento de conductos de forma ortógrada, así como blanqueamiento interno del diente. Conclusión: El plan de tratamiento en dientes con metamorfosis cálcica sin patología periapical y con compromiso estético partirá siempre desde el más conservador. Es esencial en el tratamiento de estos dientes la experiencia del operador, así como el buen manejo del microscopio y los ultrasonidos, herramientas fundamentales para su abordaje


Introduction: Calcium metamorphosis commonly occurs after traumatic injuries and is characterized by hard tissue deposits within the pulp space, partially or totally obliterating the pulp chamber and/or the root canal. This process usually causes a change in the color of the clinical crown, making it darker and more opaque. Clinical case: A 40-year-old female patient came to the clinic motivated by an aesthetic concern due to the darkening of the tooth 21. Various treatment options are proposed, until finally the endodontic treatment is chosen, as well as internal bleaching of the tooth. Conclusion: The treatment in teeth with calcium metamorphosis, without periapical pathology and with aesthetic compromise, should always be the most conservative. It is essential in the treatment of these teeth the experience of the operator, as well as the correct use of the microscope and ultrasounds, which are fundamental tools for its approach

RESUMO

Pattern recognition receptor (PRR) agonists are promising for use in modulating immune responses in clinical settings characterized by immune immaturity or deficiency. ß-Glucans derived from Ganoderma lucidum have demonstrated immune-modulatory activity both in vitro and in vivo. To evaluate the immunomodulatory activity of orally administered ß-glucans, a randomized, double-blinded, placebo-controlled clinical study was performed in asymptomatic children, aged 3 to 5 years old, from Medellin, Colombia. Primary outcomes were the circulating CD8+ T lymphocyte and natural killer cell counts; secondary outcomes were circulating lymphocyte counts (total, CD3+, and CD4+ T cells), serum concentrations of total immunoglobulin A and cytokines, and various hematological parameters. The treatments were administered daily for 12 weeks, and physical and laboratory evaluations were performed at days 0 and 84. Children in the group receiving a yogurt with ß-glucans presented a significantly higher absolute count of peripheral blood total lymphocytes (CD3+, CD4+, and CD8+ T cells) than that in the group receiving placebo. The interventions were safe and well tolerated; no abnormal increases in serum creatinine or hepatic aminotransferases occurred, and adherence was higher than 90% in the intervention groups. This study demonstrates that ß-glucans from G. lucidum increase the frequency of immune system cells in the peripheral blood; these cells are critical in the defense against infectious threats in asymptomatic children 3 to 5 years old. These findings warrant longer controlled clinical trials that aim to evaluate the efficacy of ß-glucans in preventing infections in healthy children and to define their potential to enhance lymphoid cell number and functions in various lymphoid immune deficiencies.

RESUMO

BACKGROUND: The risk factors for surgical site infections in surgery should be measured and monitored from admission to 30 days after the surgical procedure, because 30% of Surgical Site Infection is detected when the patient was discharged. AIM: Calculate the Relative Risk of associated factors to surgical site infections in adult with elective surgery. METHODS: Patients were classified according to the surgery contamination degree; patient with surgery clean was defined as no exposed and patient with clean-contaminated or contaminated surgery was defined exposed. Risk factors for infection were classified as: inherent to the patient, pre-operative, intra-operative and post-operative. Statistical analysis; we realized Student t or Mann-Whitney U, chi square for Relative Risk (RR) and multivariate analysis by Cox proportional hazards. RESULTS: Were monitored up to 30 days after surgery 403 patients (59.8% women), 35 (8.7%) developed surgical site infections. The factors associated in multivariate analysis were: smoking, RR of 3.21, underweight 3.4 hand washing unsuitable techniques 4.61, transfusion during the procedure 3.22, contaminated surgery 60, and intensive care stay 8 to 14 days 11.64, permanence of 1 to 3 days 2.4 and use of catheter 1 to 3 days 2.27. CONCLUSION: To avoid all risk factors is almost impossible; therefore close monitoring of elective surgery patients can prevent infectious complications.


Antecedentes: desde el ingreso del paciente hasta 30 días después del procedimiento quirúrgico es necesario identificar y vigilar los factores de riesgo de infección del sitio quirúrgico, debido a que 30% de esas infecciones se detectan cuando el paciente sale del hospital. Objetivo: calcular el riesgo relativo de los factores asociados con las infecciones del sitio quirúrgico en adultos con cirugía programada. Material y métodos: estudio de cohorte prospectiva de pacientes quirúrgicos clasificados según el grado de contaminación de la cirugía; expuesto si fue limpia-contaminada o contaminada, no expuesto si fue limpia. Los factores de riesgo estudiados fueron: los inherentes al paciente, pre-quirúrgicos, intraquirúrgicos y posquirúrgicos. El análisis bivariado se realizó con t de Student o U de Mann-Withney, ?2 para riesgo multivariado de riesgos proporcionales de Cox. Resultados: se estudiaron 403 pacientes durante 30 días después de operados (59.8% mujeres); 8.7% resultaron con infección del sitio quirúrgico. Los factores asociados con el análisis multivariado fueron: índice tabáquico con un riesgo relativo de 3.21, índice de masa corporal en bajo peso 3.4, técnica inadecuada de lavado de manos 4.61, transfusión durante la cirugía 3.22, cirugía contaminada 60, estancia de 8 a 14 días en terapia intensiva 11.64, permanencia 1 a 3 días con venoclisis 2.4 y con sonda vesical 1 a 3 días 2.27. Conclusión: es imposible evitar todos los factores de riesgo para infecciones del sitio quirúrgico; sin embargo, la vigilancia formal de los pacientes puede prevenir complicaciones.

RESUMO

Resumen


Introducción: un sistema activo de vigilancia de infecciones nosocomiales (IN), ahorran dinero a las instituciones, a los sistemas de salud y sobre todo impactan en la vida de los pacientes.


Objetivo: describir el comportamiento de las IN y sus repercusiones en los pacientes y un hospital de alta especialidad.


Metodología: se realizó un estudio transversal, descriptivo, donde se estudió la prevalencia de IN, sobre estancia y mortalidad atribuible por IN. Se incluyeron todos los pacientes hospitalizados de enero a junio de 2011, captados por el sistema de vigilancia de infecciones. Para el análisis se utilizaron: frecuencia, «T¼ de Student y «U¼ Mann Whitney e intervalos de confianza (IC95%).


Resultados: de 8,388 pacientes que egresaron, se identificaron 565 pacientes con un total de 81 5 IN. El promedio de edad fue 49.13±17.9 y en los pacientes con IN 49.28 ± 18.3 años. Las IN encontradas fueron neumonía 24.2%, seguida por bacteriemias 20.9%, infección de vías urinarias 15.2%, infecciones relacionadas a catéter 13%, infección de sitio quirúrgico 11.4%. La mortalidad general fue de 5.93% y la mortalidad de los pacientes con IN 25.15% con una probabilidad de muerte de 76.6% para quien desarrolla IN p<0.00, el servicio con mayor sobre estancia por IN fue hematología 1,552 días.


Conclusiones: la proporción de la mortalidad hospitalaria atribuible a NI fue 25.15%. Las IN son muy costosas para los sistemas de salud, siendo muchas de estas muertes prevenibles con un sistema de vigilancia epidemiológica de IN eficiente para establecer medidas preventivas y de control, así como, supervisión continua de las prácticas clínicas.


Abstract


Introduction: an active system of surveillance of nosocomial infections (NI) saves money for hospitals, healthcare systems, and above all, impacts the lives of patients.


Objective: Describe the behavior of nosocomial infections (NI) at the Speciality Hospital and its impact on patients and the hospital.


Methodology: transversal descriptive study was conducted from January to June 2011. Variables were prevalence, overstay and mortality attributable to NI.


All hospitalized patients in the infections surveillance system were included. Data analysis used included frequency, Student's t, Mann Whitney U test with confidence interval of 95%.


Results: of the 8,388 patients discharged from hospital, 565 patients were identified with a total of 815 NI. The average age of all patients was 49.13 ± 17.9, age of patients with IN was 49.28 + 18.3 years with a median of 50 years (p = 0.42). Pneumonia was the most common NI at 24.2%, followed by bacteremia, 20.9%, urinary tract infections, 1 5.2%, catheter-related infections, 13%, surgical site infections. 11.4%. Overall mortality was 5 .93%, and mortality of patients with NI was 25.15%. The probability of death was 76.6% for patients with NI (p <0.00). The Services with the most hospital overstays from NI were hematology with 1552 day.


Conclusions: NI are costly to hospitals and healthcare systems, many of these deaths are preventable with a system of epidemiological surveillance to establish efficient Ni prevention and control measures, and continuous clinical practice monitoring.
