ABSTRACT
Angiotensin-converting enzyme (ACE) plays an important role in the physiological control of blood pressure and inflammation. We investigated an insertion/deletion (I/D) polymorphism of the gene for ACE in relation to cardiovascular, cerebrovascular, neurodegenerative, and inflammatory diseases. The purpose of the present study was to investigate a possible association between lung cancer and insertion/deletion polymorphism of the ACE gene. A total of 125 patients with lung cancer and 165 control subjects were enrolled in the present study. ACE I/D genotypes were determined by polymerase chain reaction. Allelic frequencies and genotype distribution of the ACE I/D polymorphism in the patient group were significantly different from control subjects (ACE II genotype 29.6 vs. 17.6%, P = 0.011; ACE I allele 49.6 vs. 39.4%, P =0.009). Our data suggest that the ACE I/D polymorphism could be a risk factor for patients with lung cancer.

Hydatid cyst is a zoonotic infection that is caused by Echinococcus granulosus and alveolaris, and that can result in endemics in rural regions. Infections caused by Echinococcus granulosus are more commonly seen in our country. In this retrospective study, we aimed at discussing the experience we have accumulated on pediatric pulmonary hydatid cyst cases over the last 6 years. Between 1995-2001, in the Department of Thoracic and Cardiovascular Surgery in Gaziantep University, 38 cases underwent 39 operations due to pulmonary and hepatic hydatid cysts. Of these, 24 were males and 14 were females, with an age range of 2-16 years. Operations were frequently performed via thoracotomy. Nineteen cysts were intact, and 26 were perforated. One case had sternotomy, another had sequential thoracotomy, and the rest of the cases underwent thoracotomy, which resulted in cystotomy-capitonnage. In the postoperative period, 2 patients had sustained air leakage, and 2 other cases developed skin infections. Average hospital stay was 5 days. After the operation, the patients received chemotherapy (albendazole 10 mg/kg/day) for 1.5 months. Early or late deaths or recurrences were not observed. We conclude that cystotomy-capitonnage is a successful treatment for pediatric pulmonary hydatid cysts, as it preserves the parenchyma. Chemotherapy in the postoperative period is beneficial in preventing the recurrences.
