ABSTRACT

RESUMEN: La neoplasia quística mucinosa del páncreas (NQMP) es un tumor infrecuente, que afecta predominantemente a mujeres (90-95 %), afectando especialmente entre la quinta y séptima década de la vida; cuyo descubrimiento suele ser incidental. Por lo general, son lesiones solitarias, sin compromiso del conducto pancreático principal; poco sintomáticas y asociadas a malignidad (10 % a 40 %). El objetivo de este manuscrito fue reportar un caso de neoplasia quística mucinosa gigante del páncreas intervenida quirúrgicamente y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Mujer de 29 años, con masa abdominal poco sintomática. El diagnóstico se verificó por medio de ultrasonografía, tomografía axial computarizada y resonancia nuclear magnética. Se intervino quirúrgicamente, realizándose pancreatectomía corporocaudal con preservación esplénica, sin incidentes. La paciente fue dada de alta al quinto día, sin complicaciones, y evolucionó de forma adecuada, sin complicaciones postoperatorias. La NMQP es una lesión compleja, que puede asociarse a malignidad, pero el diagnóstico preoperatorio de malignidad no puede establecerse con seguridad. El pronóstico depende de un diagnóstico precoz y un tratamiento oportuno.


SUMMARY: Mucinous cystic neoplasm of the pancreas (MCNP) are variable types of tumors, which predominantly affect women (90-95 %), and usually appear incidentally in the 5th to 7th decade of life. They are generally solitary lesions, with no involvement of the main pancreatic duct, rarely symptomatic and are associated with malignancy (10 % to 40 %). The aim of this manuscript was to report a case of giant mucinous cystic neoplasm of the pancreas surgically treated and review the existing evidence regarding its morphological, therapeutic and prognosis characteristics. Patient: A 29-year-old woman with a slightly symptomatic abdominal mass. The diagnosis was verified with ultrasound, computed axial tomography and magnetic nuclear resonance. The patient underwent surgery; an uneventful corporocaudal pancreatectomy with splenic preservation was performed. She was discharged on the fifth day, and has evolved adequately, without postoperative complications. MCNP is a complex lesion, which can be associated with malignancy, but the preoperative diagnosis of malignancy cannot be established with certainty. Its prognosis depends on early diagnosis and timely treatment.

ABSTRACT

Abstract The present work investigates the chemical composition of seeds of Cascabela thevetioides (Kunth) Lippold, an ornamental shrub of México. Six thevetia cardiac glycosides or thevetosides (thevetin A, B, and C, acetylthevetin A, B and C) were identified from the methanol extract of seeds of C. thevetioides by High-Performance Liquid Chromatography-Mass Spectrometry and by comparison of mass spectral fragmentation patterns. Enzymatic hydrolysis of a sample of thevetosides from methanol extract of seeds and subsequent High-Performance Liquid Chromatography-Mass Spectrometry analysis yielded the monoglycosides neriifolin, acetylneriifolin and acetylperuvoside, previously reported for this plant. For the fisrt time thevetin A, B and C, and acetylthevetin A, B and C are reported as components of seeds of C. thevetioides.

ABSTRACT

Los trastornos temporomandibulares (TTM) han sido descritos como "término colectivo que encierra muchos problemas clínicos que comprometen la musculatura masticatoria, articulaciones y estructuras asociadas". Estudios epidemiológicos han reportado que éstos son comunes en niños y adolescentes, con prevalencias de 6% a 68% y, en población adulta el 75% presenta algún tipo de alteración funcional. Los propósitos de este estudio fueron conocer la prevalencia de signos y síntomas de TTM, en un grupo de escolares de Temuco, Chile y determinar tanto el efecto de diseño para un posterior estudio poblacional, como la estabilidad de los tests. Es un estudio de corte transversal, con muestra no probabilística por conveniencia y consentimiento informado, de 116 alumnos del Colegio Bautista de Temuco, quienes respondieron un test sobre síntomas subjetivos de TTM, y fueron examinados clínicamente evaluando: alteraciones, limitaciones o desviación de los movimientos mandibulares, dolor a la palpación muscular y articular, ruidos y bruxismo. El test autorreporte arrojó que: el 77.6% mostró uno o más síntomas; el 37.9% presentó ruido articular; 23.3% sintió la mandíbula rígida y un 35.3% refirió dolor de cabeza, nuca y sien. Clínicamente, el 85.3%% presentó uno o más signos de TTM. Un 50% presentó ruido articular, el 8.6% alteración apertura bucal, 18.1% disminución del movimiento en lateralidad, 8.6% sensibilidad a la palpación articular y el 4.3% y 6% a la palpación de los músculos temporal y masetero, respectivamente y el 46.6% alguna manifestación de bruxismo. Al comparar estos signos con edad y sexo, sólo hubo diferencias significativas de la edad con apertura y bruxismo (p<0.05). En conclusión, el ruido fue el signo de mayor frecuencia en esta población. Hay concordancia entre lo percibido por los adolescentes y lo observado clínicamente en cuanto a: apertura, dificultad al masticar, ruido y sensibilidad articular. En los análisis del test y retest, ...


Temporomandibular disorders (TMD) has been descrited as "Collective terms that involucre several clinical problems that compromise masticatory musculature, joints and associated structures". Epidemiologic studies have reported that there are common in children and adolescents. Showing prevalences ranging from 6% to 68% and 75% of adult population show some kind of functional alteration. The purpose of this study was to determine the prevalence of TMD signs and symptoms non existent in this commune, stablish the design effect for grade to calculate sample size for populational study and to determine stability of the test. Cross sectinal study with non probabilistic (by convenience) sample and informed consent, taken from 116 students from the Baptist School of Temuco, who answered a test inquiring about subjective symptoms and then they were clinically examinations looking for signs, like: alterations, limitations or desviations of mandibular motion; pain to joint and muscular palpation; noises and bruxism. Autoreport Test: 77.6% repot one or more symptoms, articular noise 37.9%; to feel jaw rigid 23.1% and headache, nape and temple, 35.3% Clinically: 85.3% showed one or more TMD signs; 50% joint noise; 8.6% mouth opening alteration; 18.1% diminished lateral motion; 8.6% tenderness to joint palpation; 4.3% tenderness to palpation an temporalis muscleand 6% masseterus; 46:6% showed any bruxism manifestation. Correlation between this signs with gender and age showed only significant differences for age with mouth opening and Bruxism (p<0.05) There is agreement between what was perceived by the adolescents and what was clinically obsrved in maximun opening, chewing difficulty, noise and tendernees to joint palpation. In the analysis of the test and retest, great correlations was found between the answers. No statistically significant differences were found between signs and symptoms with gender. Desing effect: 1.23.
