RESUMO

Background: Immunoglobulin E-mediated allergy to cow’s milk protein (CMP) tends to subside over years of follow-up. The gold standard for detecting such allergy has been the oral challenge test. The development of some other test for determining the correct timing of the oral challenge test would avoid unnecessary patient discomfort. The aim of this study was to determine whether monitoring cow’s milk (CM) specific IgE levels overtime can be used as a predictor for determining when patients develop clinical tolerance. Methods: A prospective 4-year follow-up study was made of 170 patients with IgE-mediated allergy to CMP, involving periodic evaluations (12, 18, 24, 36 and 48 months) with the determination of casein and CM specific IgE on each visit, along with CM challenge testing. ROC curves were used to analyse the sensitivity, specificity and predictive values of the casein and CM specific IgE levels versus the challenge test out comes at the different moments of follow-up. Results: In the course of follow-up, 140 infants (82 %) became tolerant. Specific IgE levels to CM:2.58, 2.5, 2.7, 2.26, 5 kUA/l and to casein: 0.97, 1.22,3, 2.39, 2.73 kUA/l, respectively, predicted clinical reactivity (greatest diagnostic efficiency values) at the different analysed moments of follow-up (12, 18, 24,36 and 48 months). Conclusions: Quantification of CMP specific IgE is a useful test for diagnosing symptomatic allergy toCM in the paediatric population, and could eliminate the need to perform oral challenges tests in a significant number of children

RESUMO

Objetive: Many physical or medical therapeutic approaches, systemic or local, have been suggested for treatment of Peyronie's disease. These approaches claim a discrete percentage of success in terms of clinical stabilization or improvement. The aim of our work was to evaluate the «natural history» of this disease. Method: 110 patients affected by Peyronie's disease have been observed for at least five years. At the first visit all patients maintained sexual activity not requiring surgical approach. No medical or physical treatments have been performed on these patients. All patients underwent twelve months follow up for at least 5 years evaluating the natural progression of the disease by means of ultrasound and clinical examination. We made statistical analysis (Odds ratio, P for trend) to check if there is association between clinical worsening requiring surgical treatment and: 1- age of patients, 2- diabetes, 3- presence of close relative pattern for diabetes and 4-Dupuytren contracture. Results: Regarding curvature, number and size of fibrous plaques, a consistent tendency to stabilization has been observed in the group of patients above 50 years of age. 68% of the patients belonging to the group under 50 years showed a progressive worsening of the disease requiring surgical therapy, while in the other group only 31,5% of the patients required surgery. The statistical analysis confirmed that PD worsening is more probable in the group under 50 years of age (OR=3.5, CI:2-8) and in the patients affected by diabetes (age adjusted OR=6, CI:2-19). Statistical analysis has not shown significant differences in the evolution of Peyronie's disease regarding the presence of close relative pattern for diabetes and Dupuytren contracture. Conclusion: The patients presented a discrete tendency to spontaneous stabilization. The patients who are diagnosed under the fifties have a greater probability that the disease will worsen, requiring a surgical approach. The data regarding the natural history of Peyronie's disease in not treated patients should induce caution in awarding efficacy to new pharmacological and physical treatments (AU)


Objetivo: Para el tratamiento de la enfermedad de La Peyronie se han sugerido muchos abordajes terapéuticos físicos y médicos, sistémicos y locales. Estos tratamientos suponen un discreto porcentaje de éxitos en términos de estabilización clínica o mejoría. El objetivo de nuestro trabajo es evaluar la historia natural de esta enfermedad. Métodos: 110 pacientes con enfermedad de La Peyronie fueron observados durante al menos cinco años. En la primera visita todos los pacientes mantenían actividad sexual y no tenían indicación para un abordaje quirúrgico. No se hizo tratamiento médico físico en estos pacientes. Todos los pacientes fueron seguidos de anualmente durante al menos cinco años, evaluando la progresión natural de la enfermedad por medio de ultrasonidos y exploración física. Realizamos un estudio estadístico (Odds ratio, P ) para comprobar si existía asociación entre el empeoramiento clínico que requiriera cirugía y: 1-la edad del paciente; 2-diabetes; 3- un patrón de diabetes en la familia próxima; y 4-enfermedad de Dupuytren. Resultados: En relación con la curvatura y el número y tamaño de las placas fibrosas se ha observado una tendencia hacia la estabilización del grupo de pacientes de más de 50 años de edad. El 68% de los pacientes del grupo de edad menor de 50 años mostraron un empeoramiento progresivo de la enfermedad requiriendo cirugía, mientras que en el otro grupo sólo el 31,5% de los pacientes necesitaron cirugía. El análisis estadístico confirmó que el empeoramiento de la enfermedad es más probable en el grupo menor de 50 años de edad (OR= 3,5, IC 2-8) y en los pacientes diabéticos (ajustando por edad OR = 6, IC 2-19). El análisis estadístico no ha mostrado diferencias significativas en la evolución de la enfermedad de Peyronie en cuanto a la presencia de un patrón de diabetes en los familiares cercanos o de enfermedad de Dupuytren. Conclusiones: Los pacientes presentaron una discreta tendencia hacia la estabilización espontánea. Los pacientes diagnosticados antes de los 50 tiene una mayor probabilidad de empeoramiento de la enfermedad requiriendo un abordaje quirúrgico. Los datos sobre la historia natural de la enfermedad de Peyronie en pacientes no tratados deben transmitir cautela a la hora de considerar la eficacia de los nuevos tratamientos farmacológicos y físicos (AU)

RESUMO

Objetivo: Se analiza con detenimiento la historia natural de la disección tipo B y sus distintas formas evolutivas e igualmente se sigue por separado la historia natural del hematoma de pared y de la úlcera de pared de aorta. Desarrollo. Se propone abandonar la clasificación en aguda y crónica ya que es arbitraria y basada en días naturales que no siempre tienen que ver con la evolución y la situación clínica del caso; en su contra se propone dividir las disecciones tipo B en progresivas y estabilizadas y además en complicadas y no complicadas. Se presenta un resumen de una serie propia de 91 disecciones de aorta, 59 de las cuales pertenecen a una serie histórica tratada médicamente y 32 corresponden a una serie realizada de forma prospectiva con tratamiento endovascular, se comparan los resultados de ambas. Se justifica este tratamiento en vistas a los resultados del tratamiento médico que sigue presentando un 13% de mortalidad, un 10% de afectación medular, un 22% de insuficiencia renal, un 28% de isquemia intestinal y/o periférica y un 30% de redisecciones. Conclusión. Concluimos estableciendo que ante lo impredecible de la evolución de la disección tipo B, el tratamiento médico podría sustituirse por el quirúrgico cuando a las 48 horas de su inicio no ha sido capaz de hacer desaparecer el dolor y controlar la hipertensión arterial


Aims: We perform a detailed analysis of the natural history of type B dissections and their different forms of progression. At the same time we also carry out separate examinations of the natural history of aortic wall haematomas and wall ulcers. Development. We propose giving up the practice of classifying them as acute and chronic since this is decided at random and is based on the number of days, which does not always have a clear relation to the progression and clinical situation of the case. In contrast, however, we suggest dividing type B dissections into progressive and stabilised, as well as into complicated and non-complicated cases. We report on a series of our own consisting of 91 aortic dissections, 59 of which belonged to a historical series that was treated medically and 32 from a prospective series with endovascular treatment; results from the two series are compared. This treatment is justified by the outcomes obtained with medical treatment, which continues to offer a 13% mortality rate, a 10% rate of spinal cord involvement, 22% renal failure, 28% intestinal and/or peripheral ischaemia and a 30% rate of redissections. Conclusions. We conclude by stating that, given the unpredictability of the progression of type B dissections, medical treatment could be replaced by surgery when, 48 hours after starting therapy, it has been unable to make the pain disappear and to control the high blood pressure
