The host marking pheromone application on the management of fruit flies - a review

The aim of this work was to review the role of the host marking pheromone (HMP) and its application in integrated management programs for the fruit flies. Initially the oviposition behavior of tephritids has been analyzed with emphasis on Ceratitis capitata. The deposition of HMP, which consists in the last stage of the oviposition behavior has been characterized and discussed about evolutive aspects and the biological meaning of the tephritidae communication through the HMP. Finally, the perspectives on the use of HMP in the integrated management of fruit flies have been discussed.

Anomalia de Ebstein associada a comunicação interventricular / Ebstein's Anomaly Associated to Interventricular Septal Defect

Twelve-year-old patient, with congestive heart failure and mild, caused by Ebstein's anomaly with interventricular septal defect, was studied and submitted to surgical correction which consisted in covering the interventricular defect with a path of bovine pericardium and substituting for the tricuspid valve with a biological prosthesis (porcine). After surgical correction, the patient was submitted to strict clinical and laboratorial (echocardiogram and cardiac catheterization) evaluation which presented excellent adjustment of the cardiac antriums, with improvement of myocardial function index. The problems related to the diagnosis of the association of the Ebstein's anomaly with interventricular septal defect can be solved with a well done semiology, helped by accurate laboratorial procedures like echodopplercardiogram and cardiac catheterization. The total surgical correction can be achieved with results and, with this fact, change the natural development of the disease.

Rabdomioma do ventrículo direito causando estenose pulmonar / Right ventricular rhabdomyoma causing pulmonary stenosis

The authors report a case of rhabdomyoma of the right ventricular cavity with outlet obstruction in a three-months old infant. The diagnosis was established by echocardiography. Bidimensional echocardiography study showed a polypoid tumor of the right ventricle. During the systole it was projected through the pulmonary valve, obstructing part of it. The Doppler study showed an important gradient between the right ventricle and the pulmonary artery. The resection was performed with success. The diagnosis of cardiac rhabdomyoma was made by microscopic study. It is emphasized the importance of the echocardiographic study in an infant with oligosymptomatic cardiac murmurs.
