Background & objectives:  Hydatid cyst is a major hygiene problem in Iran. In 80% of cases, only one organ is involved. However, multiorgan involvement has also been rarely reported. But it seems, the prevalence of hydatid cyst with the involvement of more than one organ in Iran is more than other world. The aim of this study was to evaluate the patients with hydatid cyst multi organ involvement in Ardabil province in northwest of Iran.
Methods: In this retrospective study, 34 patients with hydatid cyst with involvement in more than one organ were included. For each patient, a pre-designed questionnaire including name, age, education level, occupation, place of residence, cyst location, clinical manifestations and serologic test results were completed. Patients, who had previously a history of treatment due to hydatid cyst, were excluded from the study.
Results: The mean age of patients was 36.41 years. 61.8% of the patients were housewives and 64% were rural residents. The most commonly involved organs was liver and simultaneous involvement of liver and lung was observed in 38.2% of patients and was more in women. The association of the right lung cyst with the liver cysts was greater than that of the left lung. Only in 43% of the patients, the serologic test was positive for hydatid cyst, and the relationship between serologic test and type of involvement was not significant.
Conclusion: Regarding the high incidence of hydatid cyst involvement in more than one location in our region, in all patients, especially women with liver hydatid cyst, other organs, especially the lungs, should be investigated

Background & objectives: Using medications that decrease postoperative pain and opioid consumption is a widely recommended approach. The aim of this study was to evaluate the efficacy of intravenous Ibuprofen and its complication in controlling pain after abdominal surgery.
Methods: This study was a randomized, double-blind, interventional clinical trial. Sixty patients aged 20 to 60 years were candidates for abdominal surgery (inguinal hernioplasty and appendectomy). Patients were divided into two equal size groups (n=30) using a random block design method. The First group received (400 mg IV) ibuprofen every 6 hours for 24 hours as well as (15 microgram/ml bolus) fentanyl pump with PCA. Second group only received (15 microgram/ml blous) fentanyl pump with PCA. 
Results: Demographic characteristics and duration of surgery, ASA class, type of anesthesia and type of surgery were similar in the two groups. Pain severity in 24 postoperative hours was significantly lower in the ibuprofen group compared with the control group. Nausea and vomiting frequency in 24 postoperative hours was significantly lower in the ibuprofen group compared with the control group. Patients belonging to ibuprofen group were significantly more satisfied with their analgesic method.
Conclusion: Results showed that using 400 mg intravenous ibuprofen every 6 hours mitigates postoperative pain, reduces fentanyl consumption and is highly tolerated by patients.
