Authors describe characteristics of this rare disease, as cause of acute abdomen in infancy. They base this on the study of two cases. They establish criteria for differential diagnosis of acute appendicitis, as well as surgical treatment and pathological conditions found during surgery.
A sympathectomy of the left thyroid lobe was carried out in 17 guinea pigs by sectioning the inferior thyroid artery. Thirty days after the surgical procedure, the animals were killed and the thyroids, together with the trachea and esophagus, were collected for histological processing. Histological, caryometric, and folliculometric studies revealed that the nuclei and thyroid follicles of the operated lobe were significantly larger than in the control lobe. Five guinea pigs were subjected to a temperature of 2 degrees C for 10 hours prior to killing; the thyroid lobe of the control showed a significant increase in the size of the nuclei and follicles. The operated lobe, on the other hand, showed no change. These results favour the hypothesis that sympathetic innervation plays an important role in the normal functioning of the thyroid as well as in a stress situation caused by cold.
A rare case of a 16-month old infant with a mesenteric lipoma is presented. Symptomatology, diagnosis and surgical approach are discussed. Authors make a review of previously reported cases in the infant age.
Cardiac hydatid cyst is a rare disease, especially in children. An 11-year-old boy with a previous anaphylactic reaction and episodes of abdominal pain was admitted for workup of an acquired long systolic murmur. Echocardiographic investigation disclosed a tumor of the right ventricular anterior wall, with multiple loculations. Magnetic resonance imaging characterized it as a multilobular tumor with cyst formation and disclosed another cyst in the right pulmonary artery. With a positive ELISA reaction the child was admitted for surgery with the diagnosis of cardiac and pulmonary hydatid cysts. Cardiac surgery was performed with good results, followed by medical treatment with albendazole.
Forty two cases of Testicular Torsion in children aged under 9 are presented. Diagnosis and therapy are discussed; an accurate and prompt diagnosis is emphasized on to decide on the proper surgical correction to achieve testes preservation.
