” Both authors1, 12 mentioned some awareness about the quality of the meta-analysis and the studies included in it. We think that conclusion must be interpreted both in light of the included trials and considering the effects of other factors, such as baseline HCV level, sex, race, and genotype. We strongly believe more research is needed before it is concluded one peginterferon is better than the other.

“A 61-year-old woman presented with fever and right upper quadrant discomfort of 4 weeks’ duration. She lived on a farm with her husband, and they had several dogs. The husband hunted wild animals, and they ate garden-grown vegetables.
A physical examination revealed hepatomegaly. Computed tomography of the abdomen (Panel A) showed a large cystic lesion in the right hepatic lobe with internal Sitaxentan septations. Laboratory studies showed peripheral eosinophilia and abnormal liver chemistries (less than 2 times the upper limit of normal). Serology for echinococcosis was equivocal. PAIR, puncture, aspiration, injection of a scolicidal agent, and re-aspiration. Echinococcusgranulosus was strongly suspected because of the unilocular nature of the cystic lesion. Other infectious cystic diseases of the liver include Echinococcusmultilocularis and Echinococcusvogeli. These two infections were considered less likely on the basis of cyst characteristics, with E.multilocularis causing multilocular cysts and E.vogeli causing polycystic lesions. Therapy for cystic echinococcosis is based on considerations of the size, location, and manifestations of the cysts. Surgery has traditionally been the principal definitive method of treatment. In this case, surgical resection was considered; however, it was determined that because of the large size of the cyst, right hepatectomy would be required. For uncomplicated echinococcal lesions, puncture, aspiration, injection of a scolicidal agent, and re-aspiration (PAIR) constitute an alternative to surgery.
