RESUMO

This article describes data related to the research paper "Simplification of gel point characterization of cellulose nano and microfiber suspensions" [1]. The characterization of fibrillated celluloses that include cellulose nano and microfibrils (CMNFs) is a challenge for their production on an industrial scale, requiring easy techniques that control their quality and reproducibility. Gel point is a convenient parameter commonly used to estimate the aspect ratio (AR) of CMNFs. However, this estimation requires many sedimentation experiments, which are tedious and time consuming. The dataset includes all information related to the traditional experiments and to the simplified experiments for estimating gel point and AR based on only one sedimentation experiment. The full data set is useful to select the initial concentration to carry out the experimentation. This dataset also includes the information for the validation of the proposed simplified methodology and shows that the errors are lower than 7% for the gel point calculation and of 3% for the AR estimation. A larger databased of nanocellulose suspensions can be built with the reuse of this data to allow the estimation of nanocellulose properties in a future.

RESUMO

Objetivo: Estudiar la posible relación entre la ginecomastia y el cáncer de mama en el varón. Material y métodos: Estudio descriptivo retrospectivo con revisión de los pacientes varones, mayores de 14 años, con ginecomastia intervenidos quirúrgicamente en nuestro hospital desde enero del año 1996 hasta diciembre de 2009. Para el análisis de los datos, los casos se dividieron en 2 grupos, atendiendo a la benignidad o malignidad en el estudio anatomopatológico. Resultados: El número total de casos analizados fue de 49, de los que 10 presentaron un diagnóstico anatomopatológico de cáncer de mama y 39 de patología benigna. Se ha encontrado una relación estadísticamente significativa entre la edad de presentación de la ginecomastia y el riesgo relativo de padecer cáncer de mama (p = 0,002). Conclusiones: Aunque no se ha podido demostrar que la ginecomastia sea un factor de riesgo para el cáncer de mama, este debe ser un diagnóstico diferencial a tener en cuenta en pacientes con ginecomastia. Según nuestros resultados, esta sospecha debería ser mayor cuanto mayor sea la edad del paciente(AU)


Objetive: To study the possible association between gynecomastia and breast cancer in men. Material and methods: A retrospective case-control study was designed. Male patients older than 14 years old with breast disorder undergoing surgery in our hospital between January 1996 and December 2009 were included. Two groups of patients were made, those with malignant disease and those with benign lesions. Results: The total number of cases analyzed was 49, 10 with pathological diagnosis of breast cancer and 39 of benign disease. A significant difference was found only for age at onset of gynecomastia and relative risk of breast cancer (p = 0.002). Conclusions: Although it was not possible to demonstrate that gynecomastia is a risk factor for breast cancer, it must be a differential diagnosis to be considered in patients with gynecomastia. According to our results, this suspicion should be higher with increasing patient age(AU)

RESUMO

Introducción: Las microcalcificaciones de la mama son lesionesno palpables muy frecuentes. Existen numerosos procedimientospara biopsiarlas, pero la biopsia guiada por arpóncontinúa siendo la realizada con mayor frecuencia.Objetivo: El objetivo del presente estudio retrospectivo fueanalizar su utilidad en microcalcificaciones de mama.Pacientes y métodos: Se revisaron las historias clínicas de256 biopsias guiadas por arpón realizadas en nuestro hospitalentre noviembre de 1993 y diciembre de 2007.Resultados: Se realizaron un total de 256 procedimientosen 244 pacientes. La media de edad fue de 54 años (rango28-87). Un total de 192 pacientes fueron remitidas desde laUnidad de Diagnóstico Precoz del Cáncer de Mama. Las lesionesse encontraban en la mama derecha en el 54% de los casosy en la izquierda en el 46%. En 152 casos la biopsia serealizó bajo anestesia local con sedación y en 131 en régimende cirugía sin ingreso. En todos los casos se realizó una extirpaciónadecuada de las microcalcificaciones (243 en el primerprocedimiento y 13 en una reintervención). En 168 casos fueronlesiones benignas, 48 carcinomas in situ y 40 carcinomasinvasores. El valor predictivo positivo fue del 34,4%.Conclusiones: Hasta que se generalice el uso de otras técnicasmenos agresivas pero no siempre disponibles, la biopsiaguiada por arpón continúa siendo una técnica de gran utilidadpara la biopsia de microcalcificaciones no palpables de lamama(AU)


Background: Breast microcalcifications are very frequentnonpalpable lesions. There are many procedures to biopsythese lesions, but wire-guided open biopsy is still the most frequentlyperformed.Objective: The objective of the present retrospective studywas to analyze the actual usefulness of wire-guided biopsy ofbreast microcalcifications.Patients and methods: Clinical histories were reviewed of256 wire-guided biopsies performed between November1993 and December 2007 in our hospital.Results: A total of 256 procedures were performed in 244patients. The mean age was 54 years (range 28-87). A total of192 patients were referred to our service from a breast screeningcancer program. Right breast was affected in 54% andleft breast in 46%. In 152 cases the biopsy was performed undersedation and local anaesthesia, and in 131 cases it wasperformed in a one day surgery program. All the patients hada correct resection of their microcalcifications (243 during thefirst procedure and 13 during a reintervention). The numberof patients with histologicaly confirmed benign lesions was168, whereas 48 were in situ carcinomas and 40 invasivecarcinomas. The positive predictive value for malignancy forsuspicious breast microcalcifications was 34.4%.Conclusions: While other less aggressive techniques arenot always available, breast wire-guided biopsy remains beinga very useful technique to biopsy nonpalpable breast microcalcifications(AU)

RESUMO

Introducción: La biopsia de lesiones no palpables de lamama es uno de los procedimientos más dificultosos en el ámbitode la cirugía mamaria. El efecto de la especialización delcirujano en los resultados tras la biopsia guiada por arpón delas lesiones no palpables de la mama no ha sido estudiado previamente.Pacientes y métodos: Se diseñó un estudio retrospectivo,con revisión de las historias clínicas de pacientes sometidas abiopsia guiada por arpón de lesiones no palpables de la mamaen el Hospital General de Castellón entre enero de 2000 y diciembrede 2007. Se establecieron, de forma arbitraria, 2 gruposde cirujanos: aquellos que habían realizado 30 o más procedimientos(especialistas) y aquellos que habían realizadomenos de 30 (no especialistas). Se compararon la tasa de exéresiscompleta, las complicaciones, el tipo histológico y la cirugíadefinitiva.Resultados: El grupo de especialistas estuvo compuestopor 3 cirujanos y el grupo de no especialistas por 15 cirujanos.El grupo de especialistas realizó un total de 165 procedimientos(70,5%), mientras que el grupo de no especialistasrealizó 69 (29,5%). Tras comparar ambos grupos para las variablesde interés no se encontraron diferencias estadísticamentesignificativas.Conclusión: No se ha podido demostrar que la especializacióndel cirujano sea un factor determinante de los resultadostras la biopsia guiada por arpón de lesiones no palpables de lamama. No obstante, debido a las características del estudio,no se puede descartar la influencia de ciertos sesgos en los resultados(AU)


Background: Biopsies of non palpable breast lesions areone of the most difficult procedures performed in breastsurgery. The effect of the surgeon specialization upon the resultsafter wire-guided biopsies of non palpable breast lesionshas not been previously reported.Patients and methods: A retrospective study was made,involving review of the case histories of patients subjected towire-guided biopsy for non palpable breast lesions in CastellónGeneral Hospital between January 2000 and December2007. We arbitrarily established 2 groups of surgeons, thoseperforming >= 30 procedures (specialists) and those performing< 30 procedures (non-specialists). The rate of complete exeresis,complications, histologic type and definitive surgery werethen compared for both groups.Results: The group of specialists was compounded by 3 surgeonsand the non-specialists group by 15 surgeons. The groupof specialists performed a total of 165 procedures (70.5%), whilethe non-specialists group performed 69 (29.5%). When comparingboth groups for the variables of interest, no statistically significantdifferences were seen.Conclusions: It has not been possible to show that surgeonspecialization is a factor determining the results after wireguidedbiopsies for non palpable breast lesions. Nevertheless,due to the characteristics of the study, it is not possible to discardthe influence of some biases on our results(AU)

RESUMO

En 1948, Stewart y Treves comunicaron la aparición de unlinfangiosarcoma en el brazo edematoso de 6 pacientes sometidasa mastectomía radical por cáncer de mama. El síndromede Stewart-Treves describe la presentación de un linfangiosarcomao de un hemangiosarcoma sobre un linfedema crónico.Comunicamos el caso de una mujer de 74 años que fue sometidaa mastectomía radical derecha con radioterapia 23 añosantes y que consultó por la aparición de lesiones cutáneas enforma de placas violáceas en el brazo homolateral que llegarona hacerse nodulares. Tras la biopsia, el análisis histopatológicoconfirmó el diagnóstico de linfangiosarcoma. El estudio de extensiónfue negativo para metástasis. Se decidió la amputaciónde la extremidad. Seis meses más tarde, se diagnosticóuna metástasis cerebral y la paciente falleció poco tiempo después.Las opciones terapéuticas en estos casos (amputación,radioterapia y quimioterapia) son muy agresivas y ofrecen pobresresultados. Sólo un diagnóstico muy precoz, basado en lasospecha clínica, puede mejorar el pronóstico de esta complicaciónde la linfadenectomía axilar. La biopsia es obligatoriaante cualquier lesión sospechosa(AU)


In 1948, Stewart and Treves reported a lymphangiosarcomain 6 patient’s edematous arm after radical mastectomy forbreast cancer. Stewart-Treves syndrome describes a cutaneouslymphangiosarcoma or hemangiosarcoma that develops inlong-standing chronic lymphedema. We report a 74-year-oldwoman who was submitted to a right mastectomy and radiotherapy23 years before. She developed a chronic lymphedemain the same limb and fast-growing purplish lesions on thearm. These lesions became nodular. After the biopsy examinationthey were diagnosed as lymphangiosarcoma. The studyfor metastatic extension was negative. It was decided the amputationof the limb. Six months after the treatment, a brainmetastasis was diagnosed and the patient died. The therapeuticpossibilities (amputation, radiotherapy, chemotherapy) arevery aggresive and offer poor results. The physician mustmaintain a high index of suspicion in diagnosing this complicationof lymphadenectomy. If there is any doubt, biopsy is mandatory(AU)

RESUMO

CLINICAL CASE: A case of exogenous Candida parapsilosis endophthalmitis was treated first with oral fluconazol and later with intravenous Anfotericin without success. A subsequent therapy using topical fluconazole and oral itraconazole appeared to be effective in controlled the infection. DISCUSSION: Current elective treatment for fungal endophthalmitis is Anfotericine B i.v. An alternative therapy are the azoles. In the reported case itraconazole was used, although its intraocular penetration and effectiveness have not yet been satisfactorily demonstrated. The clinical response in this case leads to the possibility that intraocular oral itraconazole penetration can be sufficient to control infection in cases where the causal fungi is sensitive.

RESUMO

PURPOSE: To find out whether the opacity of the lens in well-developed cataracts might be so dense as to influence the electrophysiological readings in any way, modifying these to such an extent that they might become pathological. METHOD: A prospective study was carried out on 24 eyes from 21 patients with advanced cataracts (visual acuity from light perception and counting fingers making it impossible to see the retina). During the study, the eyes were subjected to an electrophysiological exploration: electroretinogram (ERG) and visual evoked potentials (VEP), both before and after surgery, analysing the possible changes in the recordings attribuitable to the opacity of the lens. RESULTS: No significant differences were observed in the electrophysiological readings before surgery with respect to postoperative readings, either in terms of latencies or in the amplitude of readings, in either the ERG or in the VEP in all the explored eyes. Although an increase in the amplitude and a slight wave reduction in latencies were indeed observed in the ERG following surgery, these values were not significant. CONCLUSIONS: The opacity of the lens itself does not significantly change the values of the electrophysiological readings, so that electrophysiological exploration in well-developed cataracts is considered to be most accurate test for predicting visual function in these patients.

RESUMO

PURPOSE: Assess the efficacy of corneal anterior stromal punctures as treatment for Recurrent Corneal Erosion (RCE) and relapse prevention. Two other treatments are compared: simple occlusion with antibiotic ointment, not manipulating the lesion and debridement of erosion previous to occlusion. MATERIAL AND METHOD: A retrospective study was performed on a total of 36 patients diagnosed with RCE where cases underwent different treatments and results were compared. Other general factors influencing the evolution of the illness are evaluated as well. RESULTS: No statistically significant differences were found comparing the effectiveness of these three treatments to decrease the risk of relapses in erosion. Presence of signs of map-dot-fingerprint dystrophy is common in RCE patients, however not associated with higher risk of relapse. The most frequent associated alteration is meibomitis. CONCLUSIONS: Treatment of RCE with erosion debridement previous to occlusion results in a high rate of healing and this treatment seems better than stromal punctures since it implies less potential risks. Pathogenesis of RCE still remains obscure. Association with certain dystrophys of the epithelial basal membrane could not be demonstrated in this study. However, it is possible that the presence of meibomitis, associated with lids contamination by certain strains of staphylococcus aureus, may play an important role in RCE pathogenesis (Arch Soc Esp Oftalmol 2002; 77: 257-262).

RESUMO

El rendimiento diagnóstico del 99mTc-sestamibi cambia según la localización y el tipo de hiperparatiroidismo. Análisis multivariante Objetivos. Analizar el rendimiento diagnóstico preoperatorio del 99mTc-sestamibi en el hiperparatiroidismo teniendo en cuenta diversos factores que pueden influir en el resultado, con la finalidad de determinar si es fiable la exploración quirúrgica selectiva en el tratamiento de esta enfermedad basada en los hallazgos obtenidos en la prueba.Material y método. Se estudian mediante regresión logística los resultados en 92 glándulas de 22 pacientes con hiperparatiroidismo primario y secundario. Se calcula la sensibilidad, la especificidad y los valores predictivos introduciendo como variables independientes el tipo de hiperparatiroidismo, la localización de las glándulas afectadas, los valores de calcemia y de paratohormona y la enfermedad tiroidea concomitante.Resultados. Hubo diferencias acusadas en magnitud y estadísticamente, según el tipo de hiperparatiroidismo y la localización superior, inferior o ectópica de las glándulas patológicas. Otras variables no demostraron ninguna influencia significativa. Para los adenomas, los índices diagnósticos fueron suficientemente elevados: sensibilidad del 71-94 por ciento, especificidad del 90-97 por ciento. Para las hiperplasias secundarias la sensibilidad fue muy baja (8-37 por ciento), pero con especificidades del 100 por ciento.Conclusiones. En el caso de adenomas paratiroideos, el sestamibi puede ofrecer suficiente seguridad diagnóstica como para poder justificar una exploración cervical selectiva sobre la base de los hallazgos que proporciona. En el hiperparatiroidismo secundario la prueba es poco fiable. (AU)

RESUMO

Objetivos. El objetivo principal del estudio fue valorar la influencia de diferentes factores de riesgo sobre la mortalidad de los pacientes, la influencia de dichos factores sobre la supervivencia en las perforaciones tumorales y finalmente comparar los resultados del grupo de perforaciones de etiología maligna con el de etiología benigna. Pacientes y métodos. En el presente estudio retrospectivo multicéntrico se presenta la experiencia de tres hospitales de la Comunidad Valenciana (Hospital General de Castellón, Hospital Gran Vía de Castellón y Hospital Comarcal de Vinaroz) en perforaciones de colon durante el período de tiempo comprendido entre enero de 1994 y abril de 1998. Fueron incluidos en el estudio un total de 68 pacientes, 38 varones y 30 mujeres con una edad media de 68 ñ 14 años (rango, 29-90). Se recogieron datos referentes a etiología, comorbilidad, clínica de presentación, exploraciones, hallazgos, técnica operatoria, morbimortalidad y seguimiento. Resultados. Se recogieron 13 etiologías diferentes, siendo la diverticulitis (n = 26; 38,2 por ciento) y las neoplasias (n = 21; 29,4 por ciento) las causas más frecuentes. En cuanto a los hallazgos (grado de contaminación), 17 pacientes (25 por ciento) presentaron abscesos, 15 (22,1 por ciento) peritonitis localizada, 21 (30,9 por ciento) peritonitis purulenta difusa y 15 (22,1 por ciento) peritonitis fecaloidea difusa. La estancia media hospitalaria fue de 18,3 ñ 13,8 días. Presentaron complicaciones postoperatorias 45 pacientes (66,2 por ciento), siendo las más frecuentes la infección de la herida quirúrgica (15; 22,1 por ciento), la evisceración (7; 10,3 por ciento) y el fallo multiorgánico (5; 7,4 por ciento). La mortalidad operatoria fue del 26,6 por ciento (14 pacientes). Conclusiones. La mortalidad perioperatoria es más elevada en aquellos pacientes de mayor edad, con clínica de diarrea al ingreso y a los que no se les practica resección de la zona perforada. La perforación es una complicación grave del cáncer de colon, con una mortalidad alta y mal pronóstico, presentando los pacientes con perforaciones tumorales mayor frecuencia de clínica de distensión abdominal y de complicaciones postoperatorias que aquellos con perforaciones benignas (AU)

RESUMO

BACKGROUND: The high proportion of gastric carcinomas present in an unresectable stage, together with the emergence of multimodal treatments, increases the usefulness of objective staging methods that avoid unnecessary laparotomies. METHODS: A prospective evaluation of the accuracy of laparoscopy in the staging of 71 patients with gastric adenocarcinoma is presented. Serosal infiltration, retroperitoneal fixation, metastasis to lymph nodes, peritoneal and liver metastasis, and ascites were determined in the staging workup. Sensitivity, specificity, and predictive values were calculated and compared with those obtained with ultrasonography (US) and computed tomography (CT). RESULTS: The diagnostic accuracy of laparoscopy in the determination of resectability was 98.6%. Consequently, over 40% of patients were spared unnecessary laparotomies. Laparoscopy yielded diagnostic indices superior to US and CT for all the tumoral attributes studied. Our technique permits accurate assessment and pathologic verification of liver and the peritoneal and retroperitoneal extent of tumor invasion in the majority of patients. CONCLUSIONS: Laparoscopy in gastric adenocarcinoma is a reliable technique that provides accurate assessment of resectability and stage, thus avoiding unnecessary laparotomies in patients in whom surgical palliation is not indicated. A stepwise diagnostic workup combining imaging and minimally invasive techniques is proposed.

RESUMO

Although breast cancer, germ cell tumors and other neoplasms are known to occur in patients with Klinefelter's syndrome, adrenal carcinoma has not yet been reported in such patients. We describe a rare case of severe primary aldosteronism as the unique manifestation of a large adrenocortical carcinoma in a patient with Klinefelter's syndrome. Complete biological and hormonal evaluation was performed. Surgical treatment was successful and the patient remained asymptomatic with normal biological and hormonal values after 1 year of followup.

RESUMO

A patient with common variable immunodeficiency developed lymphoid nodular hyperplasia and, subsequently, a follicular non-Hodgkin lymphoma with excellent response to chemotherapy. The patient remained in remission after 4 years. The very unusual type of this lymphoma and its localization are discussed, and the possible relations between these different conditions as a single spectrum of B lymphocyte are analyzed.
