A new method of determining the sensitivity of M. tuberculosis to chemotherapeutic agents.

Abstract

Introduction: Pulmonary hydatid cyst is a parasitic disease caused by contamination of patients by the larval form of Echinococcus granulosus. The lung is the preferential localization after the liver. Material and Methods:A retrospective study of 40 cases of hydatid cysts of the lung treated between 2011 and 2013. Purpose:To establish the epidemiological, clinical and therapeutic findings of hydatid cysts. Results:26men and 14 women were included. The average age was 36 years [13-80 years]. Rural origin was noted in 73% of cases. Hydatid contagion was noted in 80% of cases.A history of hepatic hydatid cyst was found in 10% of cases. The clinical signs were dominated by chest pain (60%of cases), hemoptysis (35%of cases), cough (30%of cases), fever (25%of cases) and hydatid vomica (20% cases). Radiological findings showed: homogeneous round opacity (60% of cases), opacity overcome by gaseous crescent (20%of cases), hydroaeric image (15%of cases), and balloon release (5%of cases). The right sidewas achievedin 50% of cases. The lesions werebilateralin 20% of cases. CT scan performed in 18 cases showed a healthy cyst (50% of cases), a complicated cyst (35%) and rupturedintothe pleura in 10% of cases.Endoscopy done in 8 patients showed hydatid membranes in 40% of cases. Hydatidserology waspositivein80% of cases.Pulmonary hydatid cyst was isolated in 34 cases, associated with a liver cyst in 4 cases and mediastinal hydatid cyst in 2 cases. Surgery was indicated in all patients. Two patients received also medical treatment with albendazole for multiple hydatid disease. The evolution was good. Conclusion:Pulmonary hydatid disease is still common in our climate.Treatment is often surgical. Prevention is essential especially in endemic areas.
