ABSTRACT

En todos los tratamientos ortodónticos, el primer objetivo a cumplir es alinear y nivelar las piezas dentales. Para tal fin, deberíamos generar espacio dentro del arco dentario. Existen tres procedimientos diferentes para lograr este objetivo, según el grado de apiñamiento dental o Índice de nance, que son los siguientes: a) stripping o desgaste interproximal, b) exodoncia de piezas dentales y c) distalamiento. La distalización de los molares es una de las técnicas más antiguas de la terapéutica ortodóntica y se han empleado distintos recursos terapéuticos para tal fin, como pendulum, jig de jans, first class, entre otros; cada uno con sus ventajas y desventajas. La introducción de los mini-implantes dentro de nuestra especialidad ha revolucionado en forma drástica los conceptos de anclaje, brindándonos movimientos dentarios sin generar efectos colaterales indeseables. El objetivo de este caso clínico, es mostrar la utilización de un Orthorama modificado y mini-implantes como distaladores de los molares superiores (AU)

ABSTRACT

Se determinó la prevalencia de mastitis, los microorganismos asociados y los factores de riesgo relacionados en explotaciones lecheras de municipios pertenecientes a la provincia de Pamplona (Norte de Santander, Colombia). Se realizó la prueba de California Mastitis Test (CMT) a 1.208 cuartos provenientes de 302 animales ubicados en 108 predios. De los cuartos positivos (de trazas a 3+), se obtuvo una muestra de leche y se realizó aislamiento microbiológico. Mediante un cuestionario se analizaron 64 variables relacionadas con las condiciones y sistema de ordeño en los predios y su correlación con la presencia de la enfermedad utilizando tablas de contingencia y la prueba chi cuadrado (χ²). Se determinó una prevalencia individual de 54,6% (165/302) (95% CI 48,8-60,3) animales positivos al CMT. En 67,6% (73/108) (95% CI 58,3-75,7) de los predios se presentó al menos un animal positivo, mientras que un total de 21,6% (260/1.208) (95% CI 19,3-23,9) de los cuartos presentaron reactividad al CMT. De las muestras en las cuales se pudo realizar aislamiento y caracterización microbiológica, en 74,4% se aisló Staphylococcus aureus, 12,3% Streptococcus agalactiae y 13,3% coliformes. Un total de 17 características se asociaron a la presencia de mastitis, mientras la totalidad de estos factores se relacionaron con la ausencia de buenas prácticas de ordeño. La presencia, principalmente de microorganismos asociados a mastitis contagiosas, evidencian la necesidad de capacitación y asesoramiento para implementar buenas prácticas de ordeño y mejorar la competitividad del sector en la región, lo que redundará en un aumento en la producción.


Mastitis prevalence, associated microorganisms and related risk factors were determined in dairy operations from municipalities belonging to the province of Pamplona (Norte de Santander, Colombia). California Mastitis Test (CMT) was performed in 1.208 quarters from 302 animals located in 108 rural properties. Milk samples from positive quarters (trace up to 3+) were obtained and submitted for microbiological isolation. Analysis of a 64 variables survey related to the milking practices in the rural properties under study and its link with the presence of the disease was performed using contingency charts and chi-square test (χ²). Determined prevalence per individual was 54,6% (165/302) (95% Cl 48.8 to 60.3) CMT positive animals. In 67,6% (73/108) (95% Cl 58.3 to 75.7) of the rural properties the presence of at least one animal testing positive was detected, whereas a total of 21,6% quarters (260/1208) (95% Cl 19.3 to 23.9) showed CMT reactivity. From the samples subjected to isolation and microbiological characterization, a total of 74.4% were compatible with Staphylococcus aureus, 12.3% with Streptococcus agalactiae and 13.3% with coliforms. A total of 17 characteristics were associated with the presence of mastitis, all of which were related to poor milking practices. The presence of contagious mastitis associated microorganisms, shows the need for training and orientation to implement proper milking practices and enhance the competitiveness of this sector in the region, which will result in an increase in production.

ABSTRACT

Se presenta el caso de un paciente con colitis ulcerativa (CU) grave de nueva aparición y diagnóstico simultáneo de infección por virus de inmunodeficiencia humana (VIH). Dos enfermedades inmunológica y fisiopatológicamente opuestas, que raramente se asocian. Incluso se plantea que en la infección por VIH, la enfermedad inflamatoria intestinal (EII) puede ser menos agresiva. El diagnóstico se convierte en un reto, dado el espectro de enfermedades que pueden afectar el colón en el contexto de infección por VIH. Asimismo, el tratamiento es controversial teniendo en cuenta que el uso de inmunomoduladores o biológicos bloquean otro componente del sistema inmune que podría potenciar el estado de inmunosupresión en este grupo de pacientes. La historia natural, el tratamiento y el pronóstico, continúan siendo un desafío para la evidencia actual.


We present the case of a patient with severe de novo ulcerative colitis (CU) and a simultaneous diagnosis of Human Immunodeficiency Virus (HIV) infection. These two immunologically and pathophysiologically opposing diseases are rarely found in association, and it has even been suggested that inflammatory bowel disease (IAS) may be less aggressive in HIV infections. The diagnosis is challenging, given the spectrum of diseases that can affect the colon in the context of an HIV infection. Treatment is similarly controversial considering that the use of immunomodulators or biological block another component of the immune system that could enhance the state of immunosuppression in this group of patients. Natural history, treatment and prognosis remain a challenge for currently available evidence

ABSTRACT

Chagas' myocardiopathy, caused by the intracellular protozoan Trypanosoma cruzi, is characterized by microvascular alterations, heart failure and arrhythmias. Ischemia and arrythmogenesis have been attributed to proteins shed by the parasite, although this has not been fully demonstrated. The aim of the present investigation was to study the effect of substances shed by T. cruzi on ischemia/reperfusion-induced arrhythmias. We performed a triple ischemia-reperfusion (I/R) protocol whereby the isolated beating rat hearts were perfused with either Vero-control or Vero T. cruzi-infected conditioned medium during the different stages of ischemia and subsequently reperfused with Tyrode's solution. ECG and heart rate were recorded during the entire experiment. We observed that triple I/R-induced bradycardia was associated with the generation of auricular-ventricular blockade during ischemia and non-sustained nodal and ventricular tachycardia during reperfusion. Interestingly, perfusion with Vero-infected medium produced a delay in the reperfusion-induced recovery of heart rate, increased the frequency of tachycardic events and induced ventricular fibrillation. These results suggest that the presence of parasite-shed substances in conditioned media enhances the arrhythmogenic effects that occur during the I/R protocol.

ABSTRACT

El dolor crónico es un problema de salud a nivel mundial. Un cuarto de los enfermos con dolor crónico tiene lumbalgia. Cerca del 38 por ciento de los sujetos con lumbalgia requieren abordaje no farmacológico. Existe controversia con respecto a la utilidad de los abordajes intervencionistas. Objetivo: Evaluar la analgesia tras la administración de esteroides por vía epidural para el tratamiento del dolor crónico lumbar. Materiales y método: Se trata de un estudio retrospectivo de casuística institucional de los casos que acuden a la consulta externa de una clínica del dolor del medio urbano. En la población que recibió esteroides por vía epidural se documento: (i) el número de consultas subsecuentes en un año después a la realización de la intervención, (ii) la intensidad del dolor mediante la escala visual análoga encada una de las consultas, (iii) causalidad del dolor lumbar, (iv) tipo de dolor, y (v) número de procedimientos. Resultados: Con respecto a la causalidad del dolor se identifico que en 72 por ciento (n=41) de los procedimientos el diagnóstico fue el de radiculopatia, seguido por canal estrecho en 16 por ciento (n=9). La intensidad del dolor mediante la EVA en la consulta antes del procedimiento fue en promedio de 7 (DS 2). Conclusiones: Los resultados con respecto a la eficaciad e esta intervención en el alivio del dolor crónico lumbar son controversiales. No obstante a dicha eventualidad, en este reporte identificamos una disminución significativa en la intensidad del dolor mediante la EVA y que se mantuvo a lo largo del tiempo...


Chronic pain is a worldwide health problem. One quarter of the patients with chronic pain have low back pain. It has been reported that 38 percent of the patients with low back pain are referred for non pharmacological management. There is controversy about the usefulness of the invasive procedures for low back pain management. Objective: To evaluate the analgesic effect of epidural steroids for the treatment of low back pain. Materials y method: This is a retrospective study of institutional cases of patients attended in a urban chronic pain clinic. From the patients that received epidural steroids information about (i) number of visits during one year after the intervention, (ii) pain intensity with the analogue visual scale, (iii) cause of pain, (iv) type of pain, and (v) number of procedures, were documented. Results: In 72 percent of the cases the cause of pain was due radiculopathy (n=41), the next mayor cause of pain was spinal stenosis (16 percent, n=9). Average pain intensity before the procedure using the VAS was 7 (SD 2). Conclusions: Results about the efficacy of epidural steroid injections for low back pain are controversial. Despite this in this report we identify a significant decrease in mean VAS value after the procedure and this finding was maintained over time....

ABSTRACT

We compared the response of temperature adaptation in preterm infants using the polyethylene wrap with and without previous drying versus the sterile preheated field. Both groups of polyethylene use achieved a mean axillary temperature of 36.5°C at 30 minutes compared with 75 minutes for the group of traditional care. At 120 minutes, the incubator temperature was higher in those using preheated field, compared with infants in the polyethylene wrap with or without previous drying, (35.15°C, 34.20°C and 34.20°C respectively; P = 0.0001). No difference in axillary or incubator temperature was found between the groups using the polyethylene wrap.

Sede: Hospital Regional Salamanca de PEMEX. Diseño: Estudio prospectivo, transversal, descriptivo y observacional. Análisis estadístico: Medidas de tendencia central. Pacientes y métodos: Se trata de un estudio en el que se incluyeron los pacientes postoperados por vía abdominal en el servicio de Cirugía General, en el periodo comprendido entre julio y diciembre del 2007. Se analizaron los pacientes que presentaron infección del sitio quirúrgico. Se excluyeron a los pacientes que no fueron intervenidos en este hospital. Las variables analizadas fueron edad, género, tipo de cirugía, patologías asociadas y complicaciones quirúrgicas. Resultados: En el periodo de estudio se analizaron un total de 105 procedimientos quirúrgicos. Hubo 55 mujeres (52.4%) y 50 hombres (47.61%), con edad promedio de 43 ± 26.5 años con un rango de 3 a 83 años. Fueron 75 pacientes de cirugía electiva y 30 se operaron como urgencia. Las cirugías realizadas fueron, en orden de frecuencia, colecistectomía, apendicectomía, plastías inguinales con colocación de malla, colocación de catéteres de Tenckhoff, laparotomías exploradoras, plastías umbilicales y funduplicaturas. Del total de procedimientos realizados se presentaron 6 pacientes (5.7%) con infección del sitio quirúrgico. Conclusión: La prevalencia de infección de la herida quirúrgica en este estudio es similar a la reportada por otros autores. Es importante contar con protocolos de prevención y tratamiento de las infecciones de las heridas quirúrgicas. Además, se debe conocer la microbiología propia de la institución y de cada servicio de atención, para un manejo adecuado y óptimo de los antibióticos.


Objective: To know the prevalence of surgical site infections in patients subjected to either elective or emergence abdominal surgery at a General Surgery service in a second level health care center. Setting: PEMEX Regional Hospital at Salamanca . Second level health care center. Design: Prospective, transversal, descriptive and observational study. Statistical analysis: Central tendency measures. Patients and methods: We included those patients subjected to abdominal surgery at the General Surgery service, between the month of July and December 2007. We analyzed those that presented infection of the surgical site. We excluded those patients that were not operated in this hospital. Analyzed variables were age, gender, type of surgery, associated pathologies, and surgical complications. Results: In the study period, we analyzed a total of 105 surgical procedures. There were 55 women (52.4%) and 50 men (47.61%), average age of 43 ± 26.5 years with a range of 3 to 83 years. Elective surgery was done in 75 patients, and 30 patients corresponded to emergency surgery. Performed surgeries were, in order of frequency, cholecystectomy, appendicectomy, inguinal plasties with mesh placement, placement of Tenckhoff catheter, exploratory laparotomies, umbilical plasties, and fundoplications. Of the total of procedures performed, six patients (5.7%) coursed with infection of the surgical site. Conclusion: Prevalence of surgical wound infection in this study is similar to that reported by other authors. It is important to count upon prevention and treatment protocols for infections of surgical wounds. Besides, the characteristic microbiology of the institution and of each service has to be known for an adequate and optimal management of antibiotics.

ABSTRACT

Patients hospitalized with unstable angina (UA) or with a non-ST segment elevation myocardial infarct (NSTEMI) are at increased risk of suffering refractory angina, recurrent myocardial infarct (MI), and death. These patients need to be evaluated more aggressively. According to the last published guidelines (2002) of UA/NSTEMI by the ACC/AHA Task Force, these patients should be categorized in a risk scale as: low, intermediate or high. This should be done in the initial evaluation, which includes: medical history, physical exam, an electrocardiogram (ECG) and cardiac markers. The TIMI risk score should also be used as complementary in this risk assessment. High risk patients, without contraindications, should be managed more aggressively with coronary angiography. On the other end, low risk patients, and some intermediate, may be evaluated more conservatively with early non-invasive studies for further assessment of ischemia and prognosis.

ABSTRACT

Two case reports of patients with known non-small cell lung cancer that developed cardiac tamponade related to metastatic pericardial disease are described. Both of these patients underwent urgent subxiphoid echocardiographic guided pericardiocentesis. They both were treated with sclerotherapy using intrapericardial bleomycin. There were no complications from these procedures and no recurrence of cardiac tamponade. They both lived more than 6 months after this intervention. This article reviews the pathogenesis, clinical presentation, diagnosis, and current therapeutic interventions of patients with neoplastic pericardial effusion and cardiac tamponade

ABSTRACT

OBJECTIVES: Describe the perioperative characteristics of the patients undergoing coronary artery bypass grafting (CABG) in San Juan, Veterans Affairs Medical Center (SJ-VAMC). Determine the in-hospital and 30-day morbidity and mortality following CABG and identify adverse predictors for postoperative complications. BACKGROUND: Preoperative risk factors for complications post-CABG have been identified; however limited data is available regarding the value of these predictors in the Puerto Rican Population. METHODS: Perioperative characteristics and 30-day complications were gathered from all patients undergoing CABG (n = 252) at the SJ-VAMC (2001-2003). Logistic regression analysis was performed to determine factors associated with the occurrence of complications. RESULTS: The population's mean age was 66.9 +/- 8.1 years. Associated illnesses included: hypertension (95.6), diabetes (57), past smoking (61), COPD (26), chronic renal insufficiency (CRI-11.5), cerebrovascular disease (CVD-20.6), disabling angina (78), 3-vessel coronary disease (75.8), significant left main stenosis (20), and non-elective surgical intervention (54). The most frequent primary complications were postoperative myocardial infarction (MI-4.8) and congestive heart failure (4.8). The 30-day mortality was 1.2. Upon multivariate analysis PRBC transfusions > 3 units was associated to increased risks of primary complications, in patients with prior history of CVD. CRI and LVEF < or = 40were independently associated to development of primary complications, in patients with prior MI and CVD. CONCLUSION: The preoperative characteristics are suggestive of an older and sicker patient that is undergoing CABG at the SJ-VAMC. Despite this, the death rate was low and the frequency of other complications comparable to the Society of Thoracic Surgeons (STS) National Adult Cardiac Database.

ABSTRACT

We analyzed growth, mortality and exploitation rate of Priacanhus arenatus, captured by the shrimp trawling fishery (1989-1996), in northeastern Venezuela. The growth coefficient (K) and the asymptotic length (L8) were estimated by length-frequency data using the Battacharya method and other routines of the FISAT program. Total mortality (Z) and exploitation (E) rates were obtained by length-converted catch curve analysis, based on length-frequency data, and the Berverton and Holt's yield per recruit model, respectively. The mean growth parameters L and K were estimated as 474.7 mm and 0.69 year(-1), respectively. Mean total mortality was 4.03 and the exploitation rate range was 0.70-0.80. Results indicated that the population is overexploited.

ABSTRACT

Se estudiaron 135 embarazadas con riesgo nutricional, con la finalidad de identificar algunos predictores antropométricos, para lo cual se siguieron por Consulta Externa Especializada 85 gestantes adolescentes con mal nutrición por defecto y exceso; tomándose como grupo control 50 embarazadas adultas pertenecientes a la misma población. La información se procesó estadísticamente y se obtuvieron parámetros antropométricos, así como la estimación del Indice Energía/Proteína, el Porciento de Grasa Corporal y el Indice Ponderal, respectivamente. Constatándose adecuados promedios de talla en los tres grupos que se comparan, la ganancia de peso durante la gestación fue significativamente superior en las adolescentes conceptuadas como bajo peso. No obstante, los mayores promedios de Indice/Energía se obtuvieron en las adolescentes con peso alto y en los controles. Existió ajuste adecuado del Porciento de Grasa Corporal y del Indice Ponderal que se comportaron como buenos predictores de la armonía neonatal. Se concluye que el control nutricional desde etapas tempranas del embarazo permite eliminar el bajo peso al nacer y contribuye a la obtención de indicadores antropométricos adecuados en los recién nacidos de las adolescentes en riesgo nutricional

Reportamos un paciente adulto con dolor abdominal epigástrico, intermitente, paroxístico, acompañado de náuseas, vomítos inquietud y angustia. A la exploración física sin alteraciones. En el laboratorio sólo leucocitosis con neurotrofilia. Estudios radiológicos, ultrasonido y tomografía abdominales, arteriografía mesentérica y laparotomía exploradora sin anormalidades. El electroencefalograma (EEG) mostró actividad lenta theta bilateral durante la hiperventilación. Se inició tratamiento con carbamazepina, permaneciendo asintomático durante nueve meses. Posteriormente tuvo una recaída por tomar irregularmente el medicamento. En ese momento los niveles séricos de carbamazapina eran bajos. En el EEG se encontraron brotes de ondas agudas difusas paroxísticas. Al llevar nuevamente los niveles séricos de carbamazepina dentro de rangos terapéuticos desapareció el dolor. Ha permanecido asintomático durante los siguientes doce meses, tomando regularmente su tratamiento

ABSTRACT

Autoantibodies to phospholopids antigens APL, are associated with a history of RSA in women without autoinmunedisease. APL interfere with the production of prostaciclin allowing the increase of thrombotic events. Phospholipids are compounds of placental mebrane structure and also they have been considered as an adhesion molecules participating in the formation of syncytotrophoblast. Trophoblastic antigens can induce the production of antiphospholipids antibodies. This antiboidies can delay the trophoblast development by the action in the adhesion molecules. We have studied 270 women with RSA and 31 women as a control group which had normal pregnancies. The testing incluided antiphospholopid antibodies and genetic evaluation of class II DQ antigens of the couple. We have showed APL titles no gretaer than 1/25 in normal pregnant women. In RSA the incidence increases in a fifteen percent with each subsequent pregnancy loss. We observed an strong correlation between maternal HLA DQ alfa 4.1 (0501) and increases in APL titles in patients who loss their pregnancy again
