Hydatid disease is an endemic zoonosis, and patients are generally from cattle- and sheep-raising regions of the world, such as Central Europe, the Mediterranean, the Middle East, China, South America, Australia, New Zealand, South Africa, and Russia (Lewall and McCorkell in Radiology 155:773-775, 1985). Furthermore, hydatid cyst is a disease of immigrants in non-endemic countries and in developed countries (Stojkovic et al. in PLoS Negl Trop Dis 6:e1880, 2012). The most common affected organs are liver and lungs. Hydatid cyst located in the subcutaneous tissue constitutes an extremely rare manifestation of the hydatid disease (Săvulescu et al. in Chir Buchar Rom 1990 105:419-422, 2010). In this study, we report an uncommon case of hydatid cyst that developed in the subcutaneous tissue of the right thigh of a patient with ultrasound, computed tomography, and magnetic resonance imaging findings.

Abant trout Salmo trutta abanticus were grown for 154 days at three salinities of 0, 9 or 18 to assess mass gain, condition factor, food conversion ratio and food consumption. Appetite was significantly higher at 0 than at salinities of 9 or 18. Salinities >18 may have detrimental effects on biomass production. The mean ± S.E. of the condition factor at the three salinities were 1.29 ± 0.20 at 0, 1.22 ± 0.22 at 9 and 1.10 ± 0.20 at 18. Fish reared at a salinity of 0 showed higher mass gain, food conversion ratio and food consumption., (© 2011 The Authors. Journal of Fish Biology © 2011 The Fisheries Society of the British Isles.)

Objectives: Conservative treatment should be tried prior to surgical treatment in knee osteoarthritis. This study was designed to evaluate the short-term effects of mud-pack therapy on pain relief and functional improvement in knee osteoarthritis in comparison with intra-articular hyaluronic acid injections., Methods: The study included 23 patients who were diagnosed as having knee osteoarthritis according to the ACR (American College of Rheumatology) criteria, and had complaints lasting for more than three months. All the patients had stage 2 or 3 osteoarthritis radiographically according to the Kellgren-Lawrence criteria. Twelve patients (3 males, 9 females; mean age 54+/-6 years; range 46 to 67 years) received mud therapy bilaterally. Mud packs were heated to 45 degrees C and applied on both knees for 30 minutes daily for a total of 12 weekdays. Eleven patients (2 males, 9 females; mean age 53+/-9 years; range 40 to 66 years) received a total of three bilateral intra-articular hyaluronic acid injections, each interspersed by weekly intervals. The patients were evaluated before and after treatment in terms of pain and functionality using the pain subscale of the WOMAC (Western Ontario and McMaster Universities) osteoarthritis index, Hospital for Special Surgery (HSS) score, and Knee Society clinical rating system (knee and function scores). The patients were followed-up for a mean of 5.9+/-6.3 months (range 4 to 8 months) after mud-pack therapy, and 5.8+/-0.8 months (range 5 to 7 months) after intra-articular hyaluronic acid injections., Results: No significant differences were found between the two groups with respect to pre-and posttreatment WOMAC, HSS, and knee and function scores (p>0.05). The scores of all instruments showed significant improvements following treatment in both groups (p<0.001). Posttreatment changes in relation to baseline scores did not differ significantly between the two groups (p>0.05)., Conclusion: Treatment of knee osteoarthritis with intra-articular hyaluronic acid injections or mud-pack therapy yielded similar results in the short-term in terms of functional improvement and pain relief. Mud-pack therapy is a noninvasive, complication-free, and cost-effective alternative modality for the conservative treatment of knee osteoarthritis.

Osteoid osteoma is a benign, osteoblastic and painful tumoral lesion. Apart from en-bloc resection, intralesional resection and percutaneous excision or destruction of the nidus, arthroscopic removal of the lesion in intraarticular locations have been reported. We present a patient with osteoid osteoma at distal femur which is accessible through knee joint, treated by arthroscopic complete excision.
