Social factors associated with pulmonary hydatid cyst in Aegean, Turkey.

BACKGROUND: Pulmonary hydatid cysts are caused by larval forms of the tapeworm Echinococcus granulosus. Hydatid disease, which is endemic in Turkey, is an important health problem in agricultural and stockbreeding areas where there are insufficient environmental health and preventive medicine services. Previous studies on this topic reported that hydatid disease was frequently associated with stockbreeding in rural areas. OBJECTIVES: In this retrospective clinical study, it is aimed to evaluate the social factors associated with pulmonary hydatid cyst in the Aegean region of Turkey. METHODS: Seventy-one pulmonary hydatid cyst cases reported between 1998 and 2010 in four hospitals in the Aegean region for which data were available on social and lifestyle factors were reviewed. RESULTS: In contrast to expectations, we found that pulmonary hydatid disease in the Aegean region was associated with city rather than rural life and with occupations other than stockbreeding. CONCLUSION: The findings are attributed to the presence of uncontrolled dogs in the city and urban environmental pollution. The offices of the public administration have a responsibility to inform citizens about the control of street animals, environmental health, and food hygiene.

Primer hydatid cyst of thymus: report of a case.

Cystic lesions in the mediastinum constitute one-fourth of all mediastinal masses and are usually identified incidentally. However, hydatid cysts very rarely present in the mediastinum. A 13-year-old male patient was admitted to our hospital because of chest pain and cough. A chest roentgenogram and computed tomography examination found a homogeneous cystic lesion with a size of 7.5 x 7 cm in the anterior mediastinum. Thymectomy was performed following a left thoracotomy in order to complete the pericystectomy. The histological diagnosis was hydatid cyst. No recurrence was observed during 1 year of follow-up.
