ABSTRACT

En los últimos 50 años la medicina ha evolucionado más que en los dos siglos anteriores. Sin embargo, existen en la actualidad multitud de patologías que la medicina contemporánea no ha sido capaz de solventar. Hasta hace tan solo unas décadas, los niños diagnosticados de cáncer fallecían en poco tiempo. Así pues, esto ha ido modificándose y más de la mitad llegan a ser supervivientes a largo plazo. Los cuidados paliativos como especialidad se han desarrollado de forma marcada en los últimos años. Sin embargo, destaca una parcela de ella que todavía se encuentra muy lejos de estar establecida, los cuidados paliativos pediátricos (CPP). Los niños presentan necesidades diferentes que es necesario atender. Se pretende revisar el concepto de CPP, haciendo hincapié en las diferencias que presentan los niños con respecto a los adultos y en su problemática específica (AU)


In the last 50 years medicine has evolved more than in the previous two centuries but there are currently many pathologies that modern medicine has not been able to cure. Until a mere few decades ago, children diagnosed with cancer died within a short time. However, this has gradually changed and, nowadays, over half of them become long-term survivors. Palliative care as a medical specialization has markedly developed in recent years. Nevertheless, there is a specific part that is still far from being established, pediatric palliative care (PPC). Children have different needs to be attended. PPC should be reviewed with a special focus on the precise differences present in children and their specific problems (AU)

ABSTRACT

Introducción: la toxicidad hepática asociada al uso crecientede productos de “remedios naturales” es un fenómeno emergente.Objetivos: valoración de las características epidemiológicas,clínicas y demográficas de los casos de hepatotoxicidad secundariosa productos herbales (PH) y suplementos dietéticos(SD).Pacientes y métodos: análisis de los casos de hepatotoxicidaddebida a PH y SD incluidos en el Registro Español de Hepatotoxicidad.Resultados: trece casos de un total de 521 casos (2%) dereacciones adversas hepáticas incluidas en el registro entre1994 y 2006, eran secundarios a PH/SD, representando el décimogrupo terapéutico responsable por orden de frecuencia,por delante de analgésicos, ansiolíticos y antipsicóticos. Nuevepacientes (69%) eran mujeres y la edad media fue de 45 años.Nueve pacientes (69%) presentaron ictericia. El tipo de dañomás frecuente fue el hepatocelular (12; 92%) y un 31% de loscasos presentaron datos de hipersensibilidad. La sustancia máscomúnmente involucrada en los casos de daño hepático fue laCamellia sinensis (23%) seguida de Rhamnus purshianus eisoflavonas (Fitosoja®, Biosoja®) con dos casos cada uno (15%).Tres casos (23%) presentaron re-exposición positiva.Conclusiones: la hepatotoxicidad originada por PH/SD noes excepcional, y su perfil es la hepatitis aguda hepatocelular ictéricapredominantemente en mujeres. La frecuente ocurrenciade reexposición positiva en estos pacientes indica un bajo índicede sospecha y un retraso o ausencia de diagnóstico de estetipo de reacción adversa


Background: toxic liver damage associated with the use ofnatural remedies is a growing health problem.Objectives: to analyze the demographics, and clinical andepidemiological characteristics of patients developing liver injuryrelated to these remedies.Patients and methods: all DILI cases associated with the useof herbal remedies (HR) or dietary supplements (DS) submitted tothe Spanish Registry were analyzed. Type of liver damage, severity,and outcome were specifically evaluated.Results: thirteen cases out of 521 DILI cases (2%) submittedto the Spanish Liver Toxicity Registry between 1994 and2006 were related to HR/DS, which ranked as the 10th therapeuticgroup with a greater number of cases and above painkillers, anxiolytics, and antipsychotic drugs. Nine patients (69%)were female (mean age 45 years). Nine cases (69%) had jaundiceat presentation. The predominating type of liver damagewas hepatocellular (12; 92%), and 31% of cases exhibited thecommon features of hypersensitivity. Camellia sinensis (3,23%) was the main causative herb, followed by Rhamnus purshianusand isoflavones (Fitosoja®, Biosoja®) (2 cases each,15%). Three cases (23%) were rechallenged with the offendingproduct.Conclusions: the incidence of hepatic damage related toHR/DS is not so rare, the most common profile of affected patientsbeing a woman with acute hepatocellular hepatitis. Lowsuspicion regarding the putative role of herbs in hepatotoxicitymakes diagnosis more difficult, and probably increases the incidenceof inadvertent rechallenge in these patients

ABSTRACT

Presentamos nuestra experiencia inicial en el tratamiento de laincontinencia fecal (IF) mediante neuromodulación de raíces sacras(NRS), a través de los resultados de un estudio prospectivo realizadocon 26 pacientes en el que se comparan los valores basales enla escala de continencia de Wexner-Cleveland y en la capacidadpara el retraso de la defecación, con los obtenidos tras un año deterapia con NRS. El estudio inicial de cada paciente incluía anamnesis,exploración general, ecografía y manometría rectal, así comounos diarios de continencia y de calidad de vida específicos para laIF de 3 semanas. Antes de la terapia con NRS, el valor medio en laescala Wexner-Cleveland fue de 15,00 ± 1,81 y el 62,50% de lospacientes tenía una capacidad de retraso de la defecación menorde 1 minuto. Tras un año de terapia con NRS, el valor medio en laescala de Wexner-Cleveland fue de 4,87 ± 2,54 (p = 0,0031) y el75,01% de los pacientes presentaba una capacidad de retraso defecatoriomayor de 15 minutos (p = 0,0018). Hacemos, además,una descripción detalla de la técnica quirúrgica de la NRS, haciendoreferencia a sus indicaciones y finalizamos revisando las distintasopciones terapéuticas para la IF mostrando nuestro algoritmo terapéuticopara esta patología. La NRS es una técnica eficaz para eltratamiento de la IF en pacientes seleccionados que no han respondidoa tratamiento conservador, biofeedback o correcciones anatómicas(esfinteroplastia), con una mínima morbilidad y susceptible derealizarse en un programa de cirugía ambulatoria


We present our initial experience in the treatment of fecal incontinence (FI) with sacral root neuromodulation (SRN) by reporting the results of a prospective study with 26 patients where baselineWexner-Cleveland scale scores and ability to delay defecationwere compard to results after one year with SRN. The initial studyof patients included history taking, general examination, anal ultrasonography,and manometry, and a three-week diary of continenceand quality of life specific for FI was used. Before SRN themean baseline Wexner-Cleveland score was 15.00 ± 1.81, and62.50% of patients could only delay defecation for less than aminute. After a year with NRS the mean Wexner-Cleveland scorewas 4.87 ± 2.54 (p = 0.0031), and 75.01% of patients could delaydefecation above fifteen minutes (p = 0.0018). We also describethe surgical technique and its indications, and finally reviewthe various therapeutical options for FI and show our algorithmfor this condition. SRN is an effective technique for the treatmentof FI in properly selected patients with no response to medicaltherapies (including biofeedback) or anatomic correction (sphincteroplasty),with efficacy, little morbidity, and a short hospital stay

ABSTRACT

Introducción: la realización de la ecografía endoanal en la fístulacompleja permite diseñar una estrategia quirúrgica personalizadaen cada caso, mejorando los resultados. Sin embargo, existendudas en la literatura acerca de su utilidad en fístulascomplejas recidivadas. El objetivo de este estudio es comparar lautilidad de la ecografía endoanal en el estudio de fístulas perianalescomplejas primarias versus recidivadas.Pacientes y método: estudio prospectivo de pacientes diagnosticadose intervenidos de fístula anal compleja. La exploraciónfísica y ecografía endoanal recogieron los datos relativos al trayectoprincipal, orificio interno, extensión en herradura y presenciade otros trayectos o cavidades en un protocolo elaborado para elestudio. Dichos datos se contrastaron posteriormente con los hallazgosintraoperatorios.Resultados: incluimos 35 pacientes, 19 (54,3%) con fístulascomplejas primarias y 16 (45,7%) con fístulas recidivadas. Deacuerdo a los hallazgos intraoperatorios, las fístulas fueron clasificadascomo transesfinteriana alta en 28 pacientes (80%), supraesfinterianaen 6 (17,1%) y extraesfinteriana en un paciente (2,9%),sin diferencias entre ambos grupos. La exploración física clasificócorrectamente 28 de los 35 trayectos fistulosos (80%), frente a los32 (91,4%) correctamente descritos por la ecografía. No encontramosdiferencias estadísticamente significativas entre el grupo defístulas primarias y el de recidivadas en cuanto a la sensibilidad,valor predictivo positivo y fiabilidad de la ecografía endoanal paraninguno de los parámetros estudiados.Conclusión: el poder diagnóstico de la ecografía endoanal no disminuyeen el estudio de las fístulas perianales complejas recidivadas


Introduction: performing anal endosonography in complexfistula-in-ano allows us to design a personalized surgical strategy ineach case, thereby improving results. However, there are doubtsin the literature as to its utility in recurrent complex fistulas. Theaim of this study was to compare the utility of anal ultrasonographyin the study of primary versus recurrent complex fistula-inano.Patients and method: prospective study of patients diagnosedand treated for complex fistula-in-ano. Physical examinationand anal ultrasonography provided data on primary track, internalopening, horseshoe extension and the presence ofsecondary tracks or cavities in a protocol designed specifically forthe study. These assessments were subsequently contrasted withoperative findings.Results: we included 35 patients, 19 (54.3%) with primarycomplex anal fistulas and 16 (45.7%) with recurrent fistulas. Accordingto the operative findings, fistulas were classified as hightranssphincteric in 28 patients (80%), suprasphincteric in 6(17.1%) and extrasphincteric in one patient (2.9%), with no differencesbetween groups. Physical examination correctly classified28 of the 35 fistulous tracks, in contrast to the 32 (91.4%) correctlydescribed on ultrasonography (80%). We did not find anystatistically significant differences between the primary and the recurrentfistula groups with regard to sensibility, positive predictivevalue and accuracy of the anal ultrasonography for any of the parametersstudied.Conclusion: the accuracy of anal ultrasonography does notdecrease in recurrent complex fistula-in-ano

ABSTRACT

Se presenta el caso de una mujer con anemia y rectorragias ocasionales, cuyo estudio objetivó una masa intestinal estenosante que finalmente resultó ser una endometriosis intestinal (EI). Realizamos además, una revisión de la enfermedad en la que se subraya la dificultad del diagnóstico prequirúrgico, dada la multitud de posibles cuadros clínicos que puede simular, y muchos de ellos son tributarios de cirugía. Resaltamos la importancia de la sospecha de EI en el diagnóstico diferencial ante toda paciente en edad fértil que curse con masa intestinal, y es necesario investigar en la anamnesis acerca de una posible sintomatología ginecológica concomitante. Para el correcto manejo y enfoque terapéutico de la EI diagnosticada prequirúrgicamente, es necesaria una cooperación adecuada entre los servicios de ginecología y cirugía general, teniendo en cuenta la afectación clínica de la paciente y la proximidad de la edad de ésta a la menopausia. Las opciones terapéuticas disponibles actualmente son: la administración de análogos de la hormona liberadora de gonadotropinas (GnRH) y la resección del segmento afectado por el endometrioma con adecuados márgenes de seguridad para evitar recidivas locales. Recientemente, se ha demostrado que el tratamiento neoadyuvante con análogos de GnRH facilita la cirugía en los casos programados de EI (AU)


We present the case of a woman with anemia and occasional rectorrhagia who was discovered to have an intestinal stricturing mass that was revealed to be an intestinal endometrioma. We provide a review of the literature on the topic and emphasize the difficulty of presurgical diagnosis because of the multitude of clinical presentations that this disease can simulate, many of which are suitable for surgical treatment. We stress the importance of including intestinal endometriosis (IE) in the differential diagnosis of all patients of reproductive age with intestinal masses and of inquiring about concomitant gynecological symptoms when taking a history. The appropriate management of EI diagnosed before surgery requires liaison between the departments of general surgery and gynecology, bearing in mind the patient's symptoms and age in relation to the menopause. Currently available therapeutic options are admi nistration of gonadotropin-releasing hormone (GnRH) analogues and resection of involved section of the intestine with adequate margins to avoid local recurrences. Recently, neoadjuvant treatment with GnRH analogues has been shown to facilitate elective surgery for EI (AU)

ABSTRACT

Objetivo: Detallar las maniobras quirúrgicas y valorar los resultados tras la realización de dacriocistorrinostomías endonasales y endocanaliculares con láser diodo, incluyéndolas ventajas y restricciones de esta cirugía. Método: Se practican 34 dacriocistorrinostomías endonasales y endocanaliculares con láser diodo bajo anestesia tópica y local en pacientes con clínica de epífora, con o sin secreción mucopurulenta, por obstrucción a nivel del conducto nasolagrimal. El estudio es prospectivo, intervencional, no randomizado y no comparativo. Se realiza vaporización de saco lagrimal, la osteotomía y la vaporización y coagulación de mucosa nasal con el láser diodo. El tiempo quirúrgico medio fue de 15 minutos (rango 9 - 25 minutos). En todos los procesos se efectúa intubación bicanalicular con tubos de silicona e hilo de prolene durante dos meses. El periodo observacional postquirúrgico fue entre 4 y 11 meses. En todos los pacientes se valoró el grado de epífora mediante la escala de Munk y la permeabilidad lagrimal con el test de tinción funcional endoscópica. Resultados: De las 34 dacriocistorrinostomías endonasales y endocanaliculares; permanecen asintomáticos 32 casos (94,11 por ciento). Dos (5,88 por ciento) pacientes precisaron de dacriocistorrinostomía endonasal con fresado por imposibilidad de perforación ósea con la fibra del láser. Dos casos (5,88 por ciento) presentaron fibrosis y obstrucción del punto lagrimal y canalículo inferior, estando sin epífora por permeabilidad del trayecto superior. Conclusiones: La dacriocistorrinostomía endonasal y endocanalicular con láser diodo es un procedimiento válido que no origina cicatriz en piel, disminuye el daño térmico canalicular, respeta el bombeo lagrimal excretor, minimiza el dolor y sangrado, y reduce el tiempo quirúrgico, siendo una cirugía ambulatoria con morbilidad operatoria y postquirúrgica mínima (AU)


AIM OF THE STUDY: To describe the surgical technique and to evaluate the clinical results after having performed the transcanalicular and endocanalicular dacryocystorhinostomies by diode laser, including the advantages and limits of this technique. METHODS: 34 were performed by diode laser in patients with clinical history of epiphora, with or without mucopurulent secretion, for nasolacrimal duct obstruction. The study was prospective, interventional, non randomized and non comparative. Diode laser was used to realize vaporization of lacrimal sac, osteotomy and vaporization with coagulation of nasal mucosa. The mean of surgical time was 15 minutes (range 7 to 29 minutes). Bicanalicular intubation was performed with a silicone tube and prolene filament for two months in all cases. Postsurgical follow-up was between 4 and 11 months. The degree of epiphora was evaluated by the Munk scale and lacrimal permeability was evaluated by endoscopic functional staining test in all cases. RESULTS: Out of the 34 DCR-EDN+ENC that were performed, 32 cases (94.11%) remain asymptomatic. Two of them (5.88%) required endonasal dacryocystorhinostomies by drilling, because the bony perforation was impossible to achieve by laser fiber. Two cases (5.88%) presented fibrosis and lacrimal and lower canaliculi obstruction, without epiphora because the superior canaliculi was permeable. CONCLUSION: Endonasal and endocanalicular dacryocystorhinostomy technique performed by diode laser is a valid method. It does not cause cutaneous scarring, it decreases thermic canalicular damage, it respects the lacrimal pump, it minimizes pain and bleeding, it needs less surgical time and it has turned into an out-patient procedure with a minimal surgical and postsurgical morbility (AU)

ABSTRACT

AIM: To test the efficacy of an ultra-short intravenous triple therapy against Helicobacter pylori infection in patients with bleeding peptic ulcer against standard oral 1-week triple therapy in a randomised, double-blind prospective trial. PATIENTS: (n = 75) with haemorrhagic peptic ulcer and H. pylori infection were randomised into: an Intravenous Group to receive omeprazole, clarithromycin and amoxicillin-clavulanic acid intravenously b.d. for 3 days followed by 7 days of oral omeprazole plus placebo of clarithromycin and amoxicillin; an Oral Group to receive intravenous omeprazole plus placebo of clarithromycin and amoxicillin-clavulanic acid followed by 7 days of oral omeprazole, clarithromycin and amoxicillin b.d. Gastric biopsies were obtained for urease test. A 13C-urea breath test was performed to check for H. pylori eradication. RESULTS: Intention-to-treat eradication was 50% (19/38) in the Intravenous Group and 78% (29/37) in the Oral Group (odds ratio 3.63; 95% confidence interval 1.32-9.94; P < 0.01; number needed to treat (NNT) = 4). Per protocol eradication was 50% (14/28) in the Intravenous Group and 86% (24/28) in the Oral Group (P < 0.005). There were no statistically significant differences in adverse events between the two treatment groups. CONCLUSIONS: An ultra-short, 3-day, intravenous, triple therapy containing omeprazole, clarithromycin and amoxicillin-clavulanic acid cannot be recommended as an effective eradication regimen for H. pylori infection related to haemorrhagic gastro-duodenal ulcer.

ABSTRACT

Presentamos un caso de displasia fibrosa monostótica localizada en el seno frontal con extensión orbitaria y persistencia tras la primera intervención, siendo operado nuevamente con reconstrucción fronto-orbitaria. La displasia fibrosa es una alteración ósea infrecuente con transformación del tejido óseo sano por otro fibro-óseo desestructurado, es de etiologia desconocida y puede asociarse a varios síndromes, entre ellos el síndrome de Albright (sólo en casos de displasia poliostótica). Su tratamiento es quirúrgico aunque presenta altas tasas de recidiva, por lo que su seguimiento debe ser continuado. (AU)


We present the case of a localized monostotic fibrous dysplasia in the frontal sinus with orbital extension and persistency after the first surgery; it had to be operated again with a fronto-orbitary reconstruction. The fibrous dysplasia is a rare bony alteration with transformation of the healthy bony tissue for a disestructuredone. Its etiology is unknown and can be associated to different syndromes, such as Albright's Disease. Its treatment is surgical, but presents a high percentage of recurrence, this is the xenson why it needs a close follow up (AU)

ABSTRACT

Objetivo. Evaluar la validez y precisión analítica y la practicabilidad del sistema medidor de la concentración de glucosa Glucocard Memory 2 diseñado para el autocontrol del paciente diabético. Diseño. Descriptivo, transversal. Validación de un instrumento de medida siguiendo las recomendaciones de la Sociedad Española de Bioquímica Clínica y Patología Molecular. Emplazamiento. Estudio realizado en un laboratorio de atención primaria. Muestra. Noventa y tres muestras de sangre de pacientes diabéticos seleccionadas mediante muestreo consecutivo de los tubos recibidos en el laboratorio para realizar el protocolo analítico de seguimiento de diabetes. Mediciones y resultados principales. La repetibilidad del sistema se estudió analizando la precisión intradía a 4 concentraciones distintas de glucosa, obteniéndose coeficientes de variación entre el 2,12 por ciento (a 410 mg/dl de glucosa) y un 4,17 por ciento (a 37,2 mg/dl). La linealidad del analizador se demostró experimentalmente entre 27 y 485 mg/dl. La exactitud se evaluó por comparación con el procedimiento habitual del laboratorio (Hitachi 747, GOD-PAP), calculando la recta de regresión mediante el método de Passing-Bablok (y = 1,01, * -2,34) y mediante la obtención del coeficiente de correlación intraclase, cuyo resultado fue del 99 por ciento. La técnica de análisis de 'error Grid' para investigar la significación clínica de las posibles desviaciones respecto al método de referencia dio un 100 por ciento de resultados dentro de la zona de exactitud clínica. El estudio de la practicabilidad mostró una gran simplicidad de manejo. Conclusiones. El Glucocard Memory 2 es un analizador para la medición de la glucemia capilar y venosa con una extrema simplicidad de manejo y unas excelentes características analíticas (AU)

ABSTRACT

Tomato plants (70 days old) were grown in hydroponic culture into a greenhouse, where supply of inorganic carbon, ammonium and calcium to saline nutrient solution, was investigated in order to reduce the negative effect of salinity. After 70 days, an ameliorating effect upon the decrease in growth observed under salinity was only observed with the treatments NaCl+Ca(2+) and NaCl+HCO(3)(-)+NH(4)(+)+Ca(2+). A large reduction of hydraulic conductance (L(0)) and stomatal conductance (G(s)) was observed with all treatments, compared with the control. However, the reductions were less when NaCl and Ca(2+) were added together. Organic acids (mainly malic acid) in the xylem were decreased with all treatments except with NaCl+NH(4)(+) and with all single treatments added together (NaCl+HCO(3)(-)+NH(4)(+)+Ca(2+)). Amino acid concentrations in the xylem (mainly asparagine and glutamine) decreased when plants were treated with NaCl and NaCl+Ca(2+), but there was a large increase in the plants treated with NaCl+NH(4)(+) or with all treatments together. As HCO(3)(-) is an important source of carbon for NH(4)(+) assimilation, the increase in the concentration of amino acids and organic acids caused by the treatments that contained NH(4)(+), support the idea that fixation of dissolved inorganic carbon was occurring and that the products were transported via the xylem to the shoot. The ameliorating effect of Ca(2+) on root hydraulic conductivity plus the increase of NH(4)(+) incorporation into the amino acid synthesis pathway possibly due to dissolved inorganic carbon fixation, could reduce the negative effect of salinity on tomato plants.

ABSTRACT

Mature individuals of Argopecten purpuratus from suspended culture in Tongoy Bay, northern Chile were conditioned at two temperatures (16 and 20 degrees C) and three different diets (mixture of pure microalgae, microalgae supplemented with lipids and microalgae supplemented with carbohydrates). The food, equivalent to 3% daily of the animal dry weight was supplied continuously by a peristaltic pump. The rates of different physiological processes were measured on 18 scallops (three replicates per temperature/diet combination) during the third week of conditioning. Nine scallops came from the group conditioned at 16 degrees C and other nine from the group conditioned at 20 degrees C (each scallop from a different tank). As in the conditioning experiment, physiological measurements were made in controlled temperature rooms using the same experimental diets. Argopecten purpuratus did not show significant differences in clearance rate between 16 and 20 degrees C when fed with pure microalgae and microalgae+lipids, showing a well known capability of bivalves to acclimate their physiological rates within a certain range of temperature. On the other hand a clear effect of the composition of the diet on the clearance rate was observed. When microalgae were supplemented with a lipid emulsion, clearance rate was highly stimulated, showing values significantly higher in comparison with either pure microalgae, or a mixed diet of microalgae+carbohydrate. These highest feeding rates can be related with the presence of essential fatty acids in the diet, which are considered as very important compounds during the gametogenesis of invertebrates as well as during the development of ova into normal larvae. Thus A. purpuratus can actively regulate clearance rate and does not simply switch between feeding and non-feeding states. The data also suggest the presence of chemical receptors at the level of the gills and/or labial palps, which seem able to detect specific nutritive compounds present in the diet. Absorption efficiency was independent of temperature and was higher with pure microalgae and with microalgae+lipids. The lowest efficiencies were recorded with the diet supplemented with carbohydrates. The energy expended in oxygen uptake and ammonia excretion was very similar in the different experimental diets and temperatures. Scope for growth in A. purpuratus appears mainly affected by the diet and not by temperature. While the lower SFG seems to be associated with diets composed of pure microalgae and microalgae+carbohydrates, the highest values being found for a diet rich in lipids. The data were in agreement with the reproductive conditioning of A. purpuratus, where the highest percentage of ripe scallops occurred in individuals fed with a diet of microalgae supplemented with lipids at both temperatures. Similarly the highest larval survival rate was obtained from gametes released by scallops conditioned with the diet containing lipids.
