Test de Zohlen y su relación con el ángulo Q en población sin dolor patelofemoral / Zohlen's test and its relation to the Q angle in a population without patellofemoral pain

Determinar qué porcentaje de una población sin dolor anterior de rodilla tiene un test de Zohlen positivo, además determinar el ángulo Q de esta población y buscar si existe alguna relación entre la positividad del test de Zohlen y alteraciones en el ángulo Q. Material y método: Estudio descriptivo-prospectivo observacional. Aplicación del test de Zohlen y medición del ángulo Q. La población se dividió en 2 grupos: test de Zohlen positivo y test de Zohlen negativo. Cuantificación y comparación de medias del ángulo Q en los dos grupos. Resultados: 90 sujetos evaluados, promedio de edad 20,18 años (18-40). Veinte sujetos (22,2 por ciento) con test de Zohlen positivo. Ángulo Q promedio en los sujetos con test de Zohlen negativo: 14,95°; ángulo Q promedio en los sujetos con test de Zohlen positivo: 16,9° (p < 0,05). Ángulo Q promedio en hombres con test de Zohlen negativo 13,4°; ángulo Q promedio en hombres con test de Zohlen positivo: 16° (p < 0,05). Ángulo Q promedio en mujeres con test de Zohlen negativo: 16,5°; ángulo Q promedio en mujeres con test de Zohlen positivo: 18°, sin diferencias estadísticamente significativas entre ambos grupos. Conclusiones: El test de Zohlen tiene una correlación positiva con el ángulo Q en sujetos de sexo masculino. Dada la correlación entre un ángulo Q alterado y la presencia de dolor anterior de rodilla, en los pacientes que presentan un test de Zohlen positivo sin haber consultado por dolor anterior de rodilla, la prevención primaria de dolor anterior de rodilla puede ser de utilidad...

To determine the percentage of a population without anterior knee pain with a positive Zohlen test, and also to determine the Q angle of this population and to determine if there is any relationship between the Zohlen test and Q angle anomalies. Methods:A prospective observational study was conducted in which Zohlen¿s test was applied and the Q angle was measured. The population was divided into 2 groups: Zohlen¿s positive and Zohlen¿s negative. Q angle was compared in the 2 groups. Results: The study included 90 subjects, with a mean age 20.18 years (18-40), of whom 20 subjects (22.2 percent) had positive Zohlen¿s test. The mean Q angle in subjects with negative Zohlen¿s test was 14.95°, and the mean Q angle in subjects with positive Zohlen¿s test was 16,9° (p<.05). The mean Q angle in men with negative Zohlen¿s test was 13.4°, and the mean Q angle in men with positive Zohlen¿s test was 16° (p < .05). The mean Q angle in women with negative Zohlen¿s test was 16.5°, with a mean Q angle of 18° in women with positive Zohlen¿s test, with no statistically significant differences found between groups. Conclusions: Zohlen¿s test has a positive correlation with the Q angle in male subjects. Given the correlation between the Q angle and the presence of anterior knee pain in patients who have a positive test without symptoms, primary prevention of anterior knee pain can be achieved...

Gross anatomy of the intestine and their peritonealfolds in the tucu - tucu (Ctenomys pearsoni)

The anatomy of the intestines and its mesenteries of Ctenomys pearsoni have not been described. In the presentstudy, ten adult Ctenomys pearsoni were studied using gross dissection. The small intestine was divided intoduodenum, jejunum and ileum as usual. The duodenum started at the pylorus with a cranial portion, whichdilated forming a duodenal ampulla. The ileum was very short and attached to the coiled cecum by means ofthe iliocecal fold. The ascending colon had one ansa with two parts, one proximal and one distal. Both partsof the ascending colon’s ansa were parallel to each other and joined by an apical flexure and the ascendingmesocolon. The descending duodenum was fixed to the proximal part of the ascending colon by a peritonealfold named accessory duodenocolic fold. The ascending duodenum was fixed by the duodenocolic fold to thedescending colon. This study indicates that there are minor differences in the divisions of the intestine andtheir peritoneal folds, as it usually happens when comparing other rodents.

Insuficiencia suprarrenal primaria por adrenalitis autoimnume / Primary adrenal insufficiency due to autoimmune adrenalitis

We report a 10 years old boy, admitted with a history of asthenia, anorexia and weight loss of 4 kg. Initial laboratory work up showed metabolic acidosis and hyponatremia. The patient had no circadian rhythm of serum cortisol and an adrenal stimulation test confirmed the presence of adrenal insufficiency. Anti-adrenal antibodies were positive. Treatment with cortisol and fluorocortisone resulted in a complete remission of symptoms.
