RESUMO

Las orejas prominentes se deben a una o varias anomalías congénitas que pueden asociarse entre sí en grados diversos. Los pabellones auriculares son considerados demasiado visibles tanto por la falta de plegamiento del antihélix, la abertura del ángulo cefaloconchal y la hipertrofia de la concha, según la clasificación de Davis. Son un problema estético frecuente, observándose en el 5% de la población. El conocimiento de la anatomía del pabellón normal y de los criterios antropométricos es indispensable. El grosor del cartílago condiciona la rigidez y la elasticidad del pabellón, mientras que sus relieves definen la forma y la posición. La finalidad en la otoplastia es corregir estas anomalías, remodelando el cartílago para obtener unas orejas con una plicatura adecuada, situadas y orientadas según parámetros estéticos, simétricas, con un tamaño y aspecto natural. Se pueden combinar distintos procedimientos quirúrgicos los cuales deben ser simples, rápidos, tener un resultado armonioso y duradero. Se realizó una revisión retrospectiva entre los años 2018 a 2020 en el Servicio de Cirugía Plástica del Hospital Tornú, en la que se presentan 4 casos de orejas prominentes a los cuales se les realizaron diferentes técnicas quirúrgicas de otoplastia (Davis, Stentstrom y Furnas). El total de los pacientes (n=4) tratados presentó un resultado satisfactorio tanto para el paciente como para el equipo quirúrgico, sin complicaciones significativas. La resolución quirúrgica de las orejas prominentes puede realizarse mediante numerosas técnicas; estas se dividen entre aquellas que realizan un procedimiento agresivo sobre el cartílago (resectivas) y las que intentan ser más conservadoras, sin resección del mismo para evitar al máximo las complicaciones. La diversidad de enfoques indica que no existe una técnica definitiva para corregir estos problemas. Las orejas prominentes o en asa, si bien no presentan alteraciones funcionales, tienen consecuencias sobre los efectos estéticos y psicológicos en el paciente que pueden ser sustanciales. Es importante conocer su base anatómica y realizar una adecuada evaluación, elegir técnicas para la corrección de la deformidad y conocer las posibles complicaciones del procedimiento para obtener un buen resultado estético y duradero.


Prominent ears are due to one or more congenital anomalies that may be associated with each other to varying degrees. The pinnae are considered too visible due to the lack of folding of the antihelix, the opening of the cephalo-conchal angle and the hypertrophy of the concha, according to the Davis classification. They are a frequent esthetic problem, being observed in 5% of the population. Knowledge of normal pinna anatomy and anthropometric criteria is essential. The thickness of the cartilage determines the rigidity and elasticity of the pinna, while its relief defines its shape and position. The purpose of otoplasty is to correct these anomalies, remodeling the cartilage to obtain ears with an adequate plication, positioned and oriented according to aesthetic parameters, symmetrical, with a natural size and appearance. Different surgical procedures can be combined, which must be simple, fast, have a harmonious and lasting result. A retrospective review was performed from 2018 to 2020 in the Plastic Surgery Department of the Tornú Hospital, presenting 4 cases of prominent ears which underwent different otoplasty surgical techniques (Davis, Stentstrom and Furnas). The total number of patients (n=4) treated presented a satisfactory result for both the patient and the surgical team without significant complications. Surgical resolution of protruding ears can be performed by numerous techniques, divided between those that perform an aggressive procedure on the cartilage (resective) and those that try to be more conservative, without resection of the cartilage to avoid complications as much as possible. The diversity of approaches indicates that there is no definitive technique to correct these problems. Prominent or protruding ears, although they do not present functional alterations, the consequences on the esthetic and psychological effects on the patient can be substantial. It is important to know their anatomical basis and to perform an adequate evaluation, to choose techniques for the correction of the deformity and to know the possible complications of the procedure in order to obtain a good esthetic and lasting result.

RESUMO

Introducción. La hipertrofia de los labios menores se define como tejido labial que sobresale más allá de los labios mayores, puede afectar de manera uni- o bilateral y resultar en dispareunia, interferencia con los deportes, dificultades con la limpieza, irritación e infecciones crónicas del tracto urinario, incomodidad para el uso de prendas ajustadas, además de trastornos psicológicos. Todos estos motivos llevan a las mujeres a la consulta. La reducción de labios menores es el procedimiento estético genital femenino más común. Este trabajo tiene como objetivo presentar técnicas de baja complejidad para resolver diferentes grados de hipertrofia de labios menores. Materiales y métodos. Estudio retrospectivo, observacional que comprendió 3 pacientes entre el periodo de marzo del 2019 a febrero 2020 que Incluyó a pacientes con hipertrofias leves y moderadas. Resultados. En 2 pacientes se realizó escisión directa y en 1, técnica del desepitelizado más lipotransferencia de labios mayores, sin evidenciar complicaciones mayores. Discusión. Si bien en la literatura se han reportado un gran número de técnicas quirúrgicas, cada una de ellas debe adecuarse al tipo de hipertrofia labial. La técnica del desepitelizado permite conservar un borde natural, con conservación de la coloración y textura original de la paciente, aporte neurovascular, pero no es conveniente utilizarla en pacientes de grados mayores de hipertrofia. La escisión directa proporciona una técnica simple para la escisión del exceso de tejido en pacientes con mayor tamaño de sus labios menores, pero elimina el contorno, la coloración y la textura naturales del borde libre, aun así, las pacientes resultan conformes con su nuevo aspecto. Conclusión. La reconstrucción de los labios menores, utilizando las técnicas de desepitelización y escisión directa, es confiable y da un resultado cosmético y funcional exitoso. Estas técnicas son de baja complejidad, tiempo operatorio breve, técnicamente reproducibles, dando gran conformidad y resultando un método seguro


Introduction. Hypertrophy of the labia minora is defined as lip tissue that protrudes beyond the labia majora, can affect unilaterally or bilaterally and result in dyspareunia, interference with sports, difficulties with cleaning, irritation and chronic infections of the urinal tract, discomfort for wearing tight clothes, in addition to psychological disorders. All these reasons lead women to the consultation. Labia minora reduction is the most common female genital cosmetic procedure. This work aims to present low complexity techniques to resolve different degrees of hypertrophy of the labia minora. Materials and methods: retrospective, observational study that comprised 3 patients between the period of March 2019 to February 2020 that included patients with mild and moderate hypertrophy. Results: Direct excision was performed in 2 patients and in 1, de-epithelialization technique plus lipotransference of the labia majora. Without showing major complications. Discussion: Although a large number of surgical techniques have been reported in the literature, each of them must be adapted to the type of lip hypertrophy. The de-epithelialization technique allows a natural border to be preserved, with preservation of the patient's original color and texture, neurovascular supply, but it is not convenient to use it in patients with higher degrees of hypertrophy. Direct excision provides a simple technique for excision of excess tissue in patients with larger labia minora, but removes the natural contour, coloration and texture of the free edge, yet patients are still satisfied with their new appearance. Conclusion. The reconstruction of the labia minora, using de-epithelialization and direct excision techniques is reliable and gives a successful cosmetic and functional result. These are low complexity techniques, short operating time, technically reproducible, giving great conformity and resulting in a safe method

RESUMO

OBJETIVO: Evaluar concordancia de sitios de hallazgos de endometriosis profunda encontrados por RM y laparoscopia. MATERIALES Y MÉTODOS: Estudio retrospectivo, no experimental, concordancia intertécnica. Se recolectaron datos en nuestra institución de todos los informes de RM de pelvis que incluyeran la palabra "endometriosis", entre mayo de 2015 y abril de 2018 (36 meses), identificando 339 registros. Se establecieron criterios de inclusión. De los 339 registros, 62 pacientes fueron excluidas por cirugía antes de la RM. Otras 243 pacientes fueron excluidas porque no presentaban registro de protocolo quirúrgico posterior a la RM. 34 pacientes cumplieron los criterios de inclusión del estudio, lo que equivale al 10% de las RM estudiadas. Se revisaron las ubicaciones de los implantes endometriósicos informados en RM y se correlacionaron con los hallazgos encontrados en la cirugía. Se confecciono tabla para identificar la presencia/ausencia de implantes en las ubicaciones descritas en la literatura. Análisis estadístico mediante software Stata, aplicando kappa ponderada con intervalo de confianza de 95%. RESULTADOS: El promedio de edad de las pacientes llevadas a cirugía fue de 38 años. Los lugares con correlación moderada-importante (0.41-0.80) correspondieron a útero, recto-sigmoides, ovario, vagina y fondos de saco. CONCLUSIÓN: La RM de Pelvis es fundamental en la evaluación de pacientes con endometriosis en las que se plantea un manejo quirúrgico, con el objetivo de caracterizar la ubicación, forma y número de lesiones, y así lograr un satisfactorio tratamiento laparoscópico.


OBJECTIVE: To assess inter-observer reliability of sites of deep endometriosis findings found by MRI and laparoscopy. MATERIALS AND METHODS: Retrospective, non-experimental study, inter-observer reliability. Data were collected at our institution from all pelvic MRI reports that included the word "endometriosis", between May 2015 and April 2018 (36 months), identifying 339 records. The following were established as inclusion criteria. Of the 339 records, 62 patients were excluded for surgery prior to MRI. Another 243 patients were excluded because they had no record of the surgical protocol after the MRI. 34 patients met the study inclusion criteria, equivalent to 10% of the MRIs studied. The locations of the endometrial implants reported on MRI were reviewed and correlated with the findings found in the surgery. A table was prepared to identify the presence / absence of implants in the locations described in the literature. Statistical analysis using Stata software, applying weighted kappa with a 95% confidence interval. RESULTS: The average age of the patients undergoing surgery was 38 years. The places with a moderate-important correlation (0.41-0.80) corresponded to the uterus, recto-sigmoid, ovary, vagina, and recto-uterine pouch. CONCLUSION: Pelvic MRI is essential in the evaluation of patients with endometriosis in whom surgical management is proposed, in order to characterize the location, shape and number of lesions, and thus achieve satisfactory laparoscopic treatment.

RESUMO

Resumen OBJETIVO Determinar la incidencia de la infección por VIH en mujeres embarazadas atendidas en el Instituto Nacional Materno Perinatal de Lima, Perú (2007-2016). MATERIAL Y MÉTODOS Estudio observacional, descriptivo y retrospectivo. Revisión de los resultados de los exámenes diagnósticos de VIH de mujeres embarazadas efectuados según la normativa nacional vigente que incluye las pruebas de tamizaje (inmunocromatografía o ELISA). Los reportes positivos se corroboran con exámenes confirmatorios (inmunofluorescencia indirecta y western blot). Determinación de la incidencia de VIH de acuerdo con la tendencia anual; aplicación de la correlación de Pearson y prueba de χ2 para comparar las características del perfil de incidencia. RESULTADOS Se tamizaron 113,258 mujeres embarazadas y la incidencia obtenida fue de 2.9 por cada mil. La tendencia anual fue errática, excepto entre 2014 y 2016 años en los que se advirtió una tendencia a disminuir. Solo se tamizó a 22.7% de las parejas masculinas en quienes la seroconcordancia fue 10.3%, y la serodiscordancia 12.4%. La frecuencia de seroconcordancia se correlacionó directamente con el porcentaje de parejas tamizadas e inversamente con la frecuencia de VIH (p<0.05). La condición de convivencia o madre soltera se asoció con mayor frecuencia a la falta de tamizaje de la pareja (p<0.001). CONCLUSIONES La incidencia de VIH confirmado fue errática (2007-2016). Deben proponerse estrategias para incrementar el tamizaje en las parejas de las embarazadas infectadas, teniendo en cuenta la alta frecuencia de inestabilidad de ese tipo de unión.


Abstract OBJECTIVE To determine the incidence of HIV infection in pregnant women treated at the National Maternal and Perinatal Institute (Lima, Peru), between 2007-2016. MATERIAL AND METHODS Observational, descriptive and retrospective study. The results of the diagnostic tests of HIV in pregnant women were reviewed, carried out according to current national regulations, which includes the screening tests (immunochromatography and / or ELISA), which in case of being reactive were corroborated by confirmatory tests (indirect immunofluorescence and Western Blot). The incidence of HIV was measured according to the annual trend, and the Pearson correlation and χ2 test were applied to compare the characteristics of the incidence profile. RESULTS 113,258 pregnant women were screened, obtaining an incidence of 2.91 per thousand pregnant women, the annual trend was erratic, except between 2014 and 2016 where there was a tendency to decrease. Only 22.73% of the couples of the pregnant women were screened, the seroconcordance was 10.3%, and the serodiscordance was 12.42%. The frequency of seroconcordance correlated directly with the percentage of sifted couples and inversely with the frequency of HIV (p <0.05). The condition of coexistence or single mother was associated more frequently with the lack of screening of the couple (p <0.001). CONCLUSIONS The confirmed incidence of HIV was erratic (2007-2016). Strategies should be elaborated to increase the screening in the pairs of the infected pregnant women, taking into account the high frequency of the instability of said union.

RESUMO

ABSTRACT: Polymerization shrinkage of composites can generate stress that results in the formation of microgaps at the resin-enamel interface and marginal leakage. The aim of the present work was to evaluate the influence of surface sealants on microleakage in composite restorations. Enamel-dentin occlusal cavities were prepared in 30 non-carious upper and lower premolars. The cavities were restored with One Coat Bond SL and Brilliant New Generation (Coletene), following the manufacturers' instructions, and polished appropriately. The samples were randomly assigned to one of the following six treatment groups: Group I (Control-no sealant); Group II: Single Bond (3M/ESPE); Group III: Perma Seal (Ultradent); Group IV: Heliobond (Vivadent); Group V: Biscover LV (Bisco); Group VI: Bioforty (Biodinâmica). The samples were then immersed in 2 % aqueous methylene blue solution for 48 hours, and thermocycled 100 times from 5 ºC to 55 ºC. The obtained specimens were ground in a bucco-palatal orientation to reach the medial plane, and observed under a stereoscopic loupe at 40X. The degree of microleakage was evaluated by assessing the penetration of the dye to the tooth-restoration interface, using a 0 to 3 grading scale. The obtained data were analyzed using the Kruskal-Wallis non-parametric test. Significant differences were observed between all rebonded groups and the control group; no differences were observed among Single Bond, Perma Seal and bioforty, or between Heliobond and Biscover LV. It would seem convenient to apply a surface sealant over composite restorations to improve marginal integrity and reduce microleakage.


RESUMEN: La contracción de polimerización de los composites puede generar fuerzas que determinan la formación de microbrechas en la interfase resina-esmalte y filtración marginal. El objetivo de este trabajo fue evaluar la influencia de los sellantes de superficie, en restauraciones de composite, sobre la microfiltración. Se utilizaron 30 premolares superiores e inferiores, libres de caries, donde se realizaron preparaciones oclusales amelodentinarias que fueron obturadas con One Coat Bond SL y Brilliant New Generation (Coletene), siguiendo las indicaciones del fabricante y pulidas adecuadamente. Luego las muestras se distribuyeron aleatoriamente en seis grupos, según los materiales experimentales: Grupo I (Control), Grupo II: Single Bond (3M/ESPE), Grupo III: Perma Seal (Ultradent), Grupo IV: Heliobond (Vivadent), Grupo V: Biscover LV (Bisco), Grupo VI: bioforty (biodinámica). Posteriormente las piezas fueron sometidas a ciclaje térmico por 100 ciclos entre 5 ºC y 55 ºC, sumergidas en una solución acuosa de azul de metileno al 2 % durante 48 horas y desgastadas en sentido V-P, hasta el plano medial, para ser observadas con lupa estereoscópica a 40 X. El grado de filtración se evaluó por la penetración del colorante en la interfase diente-restauración en una escala de O a 3. Los datos obtenidos fueron analizados mediante la muestra no paramétrica de Kruskal-Wallis. Se encontraron diferencias significativas de todos los grupos con respecto al grupo control (p= 0,0167), no existiendo significación entre Single Bond, Perma Seal y bioforty ni entre Heliobond y Biscover LV. En restauraciones de composite, sería conveniente la aplicación de sellantes de superficie para mejorar la integridad marginal y disminuir la microfiltración.

RESUMO

OBJECTIVE: To study the efficacy and safety of degludec insulin in Type 1 diabetic patients. PATIENTS AND METHOD: In a prospective study, 230 type 1 diabetics patients, average aged 34 years age and 14 years of diagnosis of diabetes and treated with two doses of insulin glargine U-100, were changed to degludec. Patients had glycosylated hemoglobins (HbA1c) greater than 10 percent. Results were recorded at 3 and 6 months with parameters clinical, biochemical, insulin requirements per kilogram of weight (U/kg/wt) and hypoglycemia. Capillary glycemia was evaluated three times a day and the dose of insulin degludec every two weeks. The statistical analysis used was average and rank, standard deviation, normal Swilk test, categorical Chi2 and continuous ANOVA or Kwallis, and p < 0.05. A psychological survey was conducted to evaluate satisfaction with the new treatment. RESULTS: Fasting blood glucose decreased from 253 (range 243-270) at 180 mg/dl (172-240) at 3 months and at 156 (137-180) at 6 months after the change insulin (p < 0.05). HbA1c, initially 10.6 percent (10.4-12.2) decreased to 8.7 percent (9.3-10.1) and 8.3 percent (8.7-9.7) at 3 and 6 months, respectively (p < 0.05). There was a decrease in basal insulin requirements from 0.7 to 0.4 U/kg/60 percent reduction in hypoglycaemia; both mild and moderate and severe. Isolated nocturnal hypoglycaemias were recorded in only 4 patients in this group. CONCLUSION: Six months of treatment with degludec insulin reduces fasting blood glucose, glycosylated hemoglobin and hypoglycemia, both mild and moderate severe and nocturnal, which makes this new ultra-long acting basal insulin a safe and effective tool for the management of type 1 diabetics patients

RESUMO

RESUMEN: En el área clínica son procedimientos comunes la venopunción, la colocación de catéteres, inyecciones intravenosas, etc. La visualización de las venas en algunas personas es compleja. En este trabajo se presenta el desarrollo de un sistema capaz de realzar la distribución de las venas en el antebrazo de una persona para, en un trabajo futuro, ayudar de forma no invasiva a localizar las venas en los procedimientos de venopunción. Para llevar a cabo el desempeño de esta tarea se utilizó una cámara web, a la cual se le ha extraído el filtro que impide el paso de luz infrarroja y es sustituido por otro que lo permite. Para mejorar la detección de las venas se le agregó a la cámara un arreglo de LEDs emisores de luz infrarroja (830nm). Las imágenes obtenidas fueron procesadas mediante la ecualización del histograma adaptable y clasificadas por dos métodos, el primero basado en el algoritmo Fuzzy C-Means, el segundo basado en un modelo probabilístico de tipo Bayes, técnicas del área de inteligencia artificial, presentadas como alternativa en el procesamiento de imágenes. Para la obtención de las imágenes se consideraron las regiones anteriores y exteriores del antebrazo izquierdo y derecho de cada sujeto generando una base de datos. Este sistema también tiene aplicación en la detección de venas varicosas debido a que se puede dar un seguimiento a la dilatación de las venas.


ABSTRACT: The venipuncture, the catheterization and intravenous (IV) injections are some of the common procedures in the clinical practice. The location of the veins may be complex in some patients. In this paper a system able to enhance the vein distribution in a patient's forearm in order to help, in future works, to locate the veins in a non-invasive way and accomplish the IV procedures, is described. To carry out this work a web cam was used, the filter that blocks out the infrared light has been removed and replaced for one who does not. To increase the vein detection an array of infrared LEDs (830 nm) was attached. The resulting images were processed using the adaptive histogram equalization and then classified by two methods, the first one based on the Fuzzy C-Means Algorithm, and the second based in a Bayesian probabilistic model. For the image acquisition, the anterior-exterior regions of the left and right forearm of each subject were considered to generate a data base. This system also has relevance in the detection of varicose veins since is able to monitor the vein dilatation.

RESUMO

En el presente los desgarros musculares son una causa muy frecuente de lesión en la práctica deportiva. Según los estudios actuales, un 30% de las lesiones en atletas afecta los músculos, siendo particularmente comunes a nivel de los isquiotibiales, el recto anterior de los cuádriceps, los gemelos y los aductores. El diagnóstico se realiza en forma sencilla mediante un estudio ecográfico. Sin embargo, existe un número importante de lesiones musculares de localización profunda e infrecuente, que pueden pasar inadvertidas en la ecografía y que causan largos períodos de inactividad para el deportista. La resonancia magnética (RM), por su resolución anatómica y capacidad multiplanar, es el método de elección para el estudio de este tipo de afecciones, ya que permite descartar otras patologías de similar presentación clínica y realizar un diagnóstico específico. En este artículo describimos los desgarros musculares de localización inusual, particularmente los de localización pelviana, evaluando también la pared torácica, abdominal y miembros superiores e inferiores. En todos los casos, se usaron equipos de alto campo 1.5 y 3 Tesla.


Muscle injuries are currently particularly frequent among people who participate in sports. Current studies show that 30% of injuries in athletes affect muscles, with hamstrings, quadriceps, gastrocnemius, and adductors being particularly prevalent. The diagnosis is easily made with an ultrasound study. However, there are a significant number of muscle injuries, considered uncommon, that may be not be detected by ultrasound, mainly because of their depth, and could be responsible for long periods of inactivity for the sportsman. Magnetic resonance imaging (MRI), with a better anatomical resolution and multiplanar capability, is the method of choice for detecting the precise location and severity of the injury and can establish their severity. The aim of this article is to review muscle tears of unusual location, particularly in the pelvic area, but also evaluating the chest wall, abdomen, and upper and lower limbs. All patients were evaluated by 3 and 1.5 Tesla MRI units.

RESUMO

Beta-adrenergic receptor (βAR)-dependent blood vessel relaxation is impaired in older animals and G protein activation has been suggested as the causative mechanism. Here, we investigated the role of βAR subtypes (β1AR, β2AR, and β3AR) and cAMP in maturation-dependent vasorelaxation impairment. Aortic rings from 15 Sprague-Dawley male rats (3 or 9 weeks old) were harvested and left intact or denuded of the endothelium. Vascular relaxation in aortic rings from younger and older groups was compared in the presence of βAR subtype agonists and antagonists along with cAMP and cGMP antagonists. Isolated aortic rings were used to evaluate relaxation responses, protein expression was evaluated by western blot or real time PCR, and metabolites were measured by ELISA. Expression of βAR subtypes and adenylyl cyclase was assessed, and cAMP activity was measured in vascular tissue from both groups. Isoproterenol- and BRL744-dependent relaxation in aortic rings with and without endothelium from 9-week-old rats was impaired compared with younger rats. The β1AR antagonist CGP20712A (10-7 M) did not affect isoproterenol or BRL744-dependent relaxation in arteries from either group. The β2AR antagonist ICI-118,551 (10-7 M) inhibited isoproterenol-dependent aortic relaxation in both groups. The β3AR antagonist SR59230A (10-7 M) inhibited isoproterenol- and BRL744-dependent aortic ring relaxation in younger but not in older rats. All βAR subtypes were expressed in both groups, although β3AR expression was lower in the older group. Adenylyl cyclase (SQ 22536) or protein kinase A (H89) inhibitors prevented isoproterenol-induced relaxation in younger but not in older rats. Production of cAMP was reduced in the older group. Adenylyl cyclase III and RyR3 protein expression was higher in the younger group. In conclusion, altered expression of β3AR and adenylyl cyclase III may be responsible for reduced cAMP production in the older group.

RESUMO

Objective: female sexual dysfunction (FSD) in diabetic women, is a topic poorly studied. The aim of this study is to determine the prevalence of FSD in typ1 1 and typ2 diabetic patients (T1D and T2D) compared with non diabetic controls. Patients and Method: interview under written consent 24 diabetic patients attended at Diabetes Unit of the San Juan de Dios Hospital and 24 healthy controls. Inclusion criteria: diagnosis of diabetes mellitus over one year, age 18-75 years old and stable partner for over a year. Exclusion criteria: antidepressants treatment. The validated survey by Rosen et al. was applied. Female Sexual Function Index (FSFI), of 19 questions that assess 6 areas of sexual function: desire, lubrication, excitement, orgasm, satisfaction and pain. A total score of 26.55 or less diagnosed DSF. In diabetic patients the metabolic control, lipid profile, creatinine and glycated hemoglobin A1c (HbA1c) was recorded. Statistical analysis was performed using median, range and Mann Whitney test. Percentages of sexual dysfunction was analysed by chi². It was considered significant at p < 0.05. Results: the results of the FSFI survey were divided and related to menopause. In premenopausal diabetic group (n = 11), the average score was 31.1 versus 32.5 in controls (NS) and in postmenopausal diabetic group (n = 13) the average score was 23,1 versus 28,5 (p = 0.05). The overall frequency of DSF in premenopausal diabetic women was 27.3 percent and 6.3 percent in controls (NS), in postmenopausal reached 69.2 percent and25.0 percent in controls (p = 0.01 ). Conclusion: in diabetic patients sexual dysfunction was more frequent than in controls; in premenopausal women the most affected area is the excitement and in postmenopausal women was lubrication.

RESUMO

Ketosis prone type 2 diabetes (KPD) is presently a well-defined clinical entity, characterized by a debut with severe hyperglycemia and ketoacidosis similar to the presenting form of Type 1 diabetes mellitus (DM1). However, it appears in subjects with Type 2 diabetes mellitus (DM2) phenotype. This situation is caused by an acute, reversible dysfunction of the beta cell in individuals with insulin resistance. Once the acute stage subsides, patients behave as having a DM2 and do not require insulin treatment. They should be kept on a diet and oral hypoglycemic drugs due to their susceptibility to have recurrent acute ketotic decompensations.

RESUMO

Introducción: La incidencia de trombos cardíacos en recién nacidos (RN) ha aumentado con el uso de catéteres venosos centrales. La trombólisis con activador del plasminógeno tisular recombinante (rTPA) se ha utilizado como alternativa a la heparina en trombos gigantes con riesgo vital y de embolización. Nuestro objetivo fue describir la respuesta y las complicaciones relacionadas con el uso del rTPA en el manejo de trombos cardíacos con riesgo vital en RN. Pacientes y método: Estudio retrospectivo de 8 RN, 7 prematuros, con trombos cardíacos en los cuales se utilizó rTPA. Se analizó la edad gestacional y al diagnóstico, peso, sexo, enfermedades asociadas, hemograma, niveles de fibrinógeno, dímero D, tiempo parcial de tromboplastina activada y de protrombina, antes y al término de la infusión de rTPA. El diagnóstico del trombo se realizó por ecocardiografía doppler. La indicación de rTPA fue trombo mayor de 10 mm o que ocupara más del 50% de la cavidad donde se localizaba; aumento del tamaño a pesar del tratamiento con heparina, aspecto fragmentado y lobulado con riesgo embólico pulmonar o sistémico o que comprometiera la función valvular o cardíaca. Resultados: Cuatro hombres; peso promedio de 1.580 g. La principal enfermedad fue la sepsis (7/8), se usó catéter venoso central en todos, la vena cava superior fue la localización más frecuente, con tiempo promedio de instalación previo al diagnóstico de 12 días. En 7/8 RN los trombos se ubicaron en la aurícula derecha, con un tamaño entre 7 a 20 mm. Tres pacientes recibieron heparina de bajo peso molecular previo al uso de rTPA, se realizaron entre uno a 5 ciclos con rTPA. En 4 pacientes se logró resolución completa del trombo a los 3,5 días en promedio. No hubo embolia ni fallecidos. Cuatro pacientes presentaron hemorragia intracraneana grado I, sin secuelas en el seguimiento. Conclusión: Este estudio constituye la primera serie de neonatos tratados con rTPA en Chile, lográndose la resolución completa del trombo en un 50% de los RN y parcial en el resto, permitiendo con ello disminuir el riesgo vital secundario a este proceso patológico.


Introduction: The incidence of cardiac thrombi in newborns has increased with the use of central venous catheters. Thrombolysis with recombinant tissue plasminogen activator (rTPA) has been used as an alternative to heparin in life threatening giant thrombus and embolization. The aim of this study is to describe the response and complications related to the use of rTPA in the management of life- threatening cardiac thrombi in newborns. Patients and method: The medical records of 8 newborn were reviewed in a retrospective study, of whom 7 were preterm with cardiac thrombi, and rTPA was used in all of them. Results: The patients included 4 males with a mean weight of 1580 gr. The principal pathology was sepsis (7/8), all of them used venous central catheter. The superior vena cava was the most frequent location, with a mean time of installation before the diagnosis of 12 days. RN 7/8 thrombi were located in the right atrium with a size between 7 to 20 mm. Three patients received low molecular weight heparin prior to using rTPA. They received between 1 to 5 cycles with rTPA. In 4 patients complete resolution of the thrombus was achieved in a mean of 3.5 days. Four patients had intracranial haemorrhage grade I, without sequelae at follow-up. There were no deaths or embolism. Conclusion: This study is the first series of infants treated with rTPA in Chile, and where its use has quickly achieved complete resolution of the thrombus in 50% of cases, and partially in the others, thus reducing the secondary life-threatening risk of this disease.

RESUMO

In patients with diabetes type 1 (T1D) glycemic control remains suboptimal, despite the availability of new insulin analogues and continuous infusion systems. Metformin may be a complementary therapy regarding to intensified insulin therapy since a significant percentage of T1D have insulin resistance (IR). Objective: To analyze the clinical, anthropometric and metabolic effects of the combination of metformin to insulin therapy in T1D patients. Subjects and Method: 34 T1D patients, 15 men and 19 women, mean age 41 years (range 20-64) metformin 850 mg / day was associated for 6 months (group 1) and retrospectively evaluated 18 T1D, 9 men and 9 women, age average 34 years (range 17-58), who received metformin for 36 months (group 2). It was recorded before and after treatment with metformin: nutritional status, waist circumference, index waist / hip, glucose fasting, glycosylated hemoglobin (HbA1c), HDL cholesterol, triglycerides, systolic and diastolic blood pressure (BP), glucose uptake (UG) and insulin dose (U/kg). Statistical analyses. Clinical and biochemical parameters were expressed as median, range or percentage (percent). For the statistical significance were used chi2and Fisher exact and Mann Whitney test; and was established as significant at p <0.05. Results: In group 1 significantly decreased waist circumference in men and women and improved fasting glucose, HbA1c, systolic blood pressure and triglycerides. In group 2, waist circumference and systolic blood pressure was also reduced. Conclusion: In T1D patients with clinical signs of IR the association of metformin to insulin therapy may be useful.

RESUMO

Although it has been treated in a limited way the relationship between diabetes and hematopoietic system, there is evidence demonstrating thedeleterious effect of hyperglycemia on the three cell lines: red blood cells, white cells and platelets. Different forms of anemia associated with hyperglycemia are analyzed and erythrocyte alterations observed in diabetes. In chronic decompensated patients have been demonstrated alterationsof monocytes, lymphocytes and polymorphonuclear particularly, with decreased chemotaxis, adherence, phagocytosis and opsonization. Hyperglycemia determines a prothrombotic state by platelet hyperreactivity, which is a marker of inflammation...

RESUMO

The presence of insulin resistance (IR) has been indirectly assessed in Type 1 Diabetics (T1DM) through the detection of Metabolic Syndrome (MS), by applying criteria for Type 2 Diabetics(T2DM). In the EDC study (the Pittsburg Epidemiology of Diabetes Complications) a formula applicable to T1DM was validated, quantifying IR through the glucose uptake (GU) employing the usual clinical and laboratory parameters, in patients with HbA1c < 11.4 percent. Objectives: To determine in T1DM whether there exists a relationship between the presence of MS according to the Modified NCEP/ATPIII criteria and IR quantification through assessment of the glucose uptake or GU. Patients and Method: The modified NCEP/ATPIII criteria were applied to 150 T1DM patients, and those with more than 3 altered parameters were classified as MS carriers. IR was quantified through the glucose uptake (GU), applying the formula for Estimated Glucose Disposal Rate (GDR-EDC). Results: 26.6 percent of the T1DM (40 patients) complied with the modified NCEP/ATPIII criteria. When the formula for GU was applied (31 patient), 90.3 percent of the T1DM showed insulin resistance (GU value < 8.77). And when applied to 124 patients (T1DM with and without MS and HbA1c < 11,4 percent) 75 percent showed IR...

RESUMO

We report a 71 years old male with high blood pressure. During the postoperative follow up after a prostatectomy for a benign prostate hyperplasia, a pulsatile mass was palpated in the left inguinal region. A chest, abdomen and lower limb AngioTC, disclosed a unique sacular aneurysm in the left common femoral artery. The patient was subjected to a surgical excision of the aneurysm, with a favorable postoperative evolution.

RESUMO

Background: The concept insulin resistance as the basis for a series of metabolic alterations and diseases was introduced by Gerald Reaven in 1988, when he described a cluster of alterations that named syndrome X. Aim: To review and discuss the present information about insulin resistance (IR) and metabolic syndrome (MS). Material and methods: The IR concept is defined,the affected metabolic ways, its consequences and relationship with different diseases are presented. The importance of central obesity with its metabolic, inflammatory and prothrombotic consequences playing a key role in cardiovascular risk, is discussed. The cluster of factors focused on cardiovascular disease and eventually diabetes is named MS. Several definitions of MS are analyzed and compared. A proposition is made about the definition to be used in the Chilean population. Differences between IR syndrome and MS are discussed. Diagnostic methods of IR and MS are presented, recommendations are made about their usefulness and reliability. Non pharmacological and pharmacological treatments of IR and MS are analyzed. Other related diseases, such as polycystic ovary syndrome, non alcoholic steatohepatitis and sleep apnea are discussed. Conclusions. Until further studies are made to define a local waist circumference cut-off associated with high risk, the ATPIII MS definition is preferred. A clinical approach is recommended for diagnosis. A search for all components of the MS is important. There is no evidence about the benefits of MS treatment on the prevention of cardiovascular diseases or diabetes. Evidence supports the use of lifestyle changes and some drugs, such as metformin on the prevention of diabetes in prediabetic states.
