Liposarcoma is a rare mesenchymal malignant tumor which usually originates in the retroperitoneum and extremities. From 1973 till now about 10 cases of primary liver liposarcoma have been reported. We present the eleventh case in a young adult female with uncommon presentation. She suffered from a huge mass in the right portion of the liver with clinical manifestations of sepsis and respiratory distress. Despite aggressive surgery, tumor recurrence after six months led to death after a year. Hepatectomy is the best strategy to achieve long term survival for patients.Trials of preoperative radiation therapy with or without intraoperative irradiation are underway.}, Keywords = {liver, liposarcoma hepatectomy}, volume = {21}, Number = {3}, pages = {167-172}, publisher = {Iran University of Medical Sciences}, url = {http://mjiri.iums.ac.ir/article-1-332-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-332-en.pdf}, journal = {Medical Journal of The Islamic Republic of Iran (MJIRI)}, issn = {1016-1430}, eissn = {2251-6840}, year = {2007} } @article{ author = {Ghanei, E. and Homayooni, M. and Nasrollahi, A.}, title = {Rhabdomyolysis and thinner intoxication}, abstract ={ Abstract We report a case of paint thinner intoxication by inhalation, with rhabdomyolysis, renal failure, skin lesions and severe sciatic nerve lesion at gluteal region.}, Keywords = {thinner intoxication, rhabdomyolysis, acute renal failure}, volume = {21}, Number = {3}, pages = {162-166}, publisher = {Iran University of Medical Sciences}, url = {http://mjiri.iums.ac.ir/article-1-331-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-331-en.pdf}, journal = {Medical Journal of The Islamic Republic of Iran (MJIRI)}, issn = {1016-1430}, eissn = {2251-6840}, year = {2007} } @article{ author = {Sabzi, F. and Teimouri, H.}, title = {Variables that predict reintubation after open-heart surgery}, abstract ={ Abstract Background: This study sought to determine patient characteristics, process of care, and outcome as predictors of reintubation after open-heart surgery. Methods: We performed a retrospective case control study that included all patients undergoing cardiac surgery who required reintubation and an equal number of control patients not requiring reintubation. Putative risk factors were analyzed univariately by Moses, Kroskal Willis and χ2 tests. Results: Of the 300 consecutive patients reviewed, 39 required reintubation for cardio- respiratory reasons. Univariate predictors of reintubation (P= 0.05) were preoperative CO2, ejection fraction, weight, diabetes, and intra-operative fluid balances. Multivariate predictors of reintubation for each group (with cardio-respiratory reasons) and for all patients were determined and included preoperative PaCO2, type of operation, ejection fraction (EF), pre- operative PaO2, number of grafts, age, intra-aortic balloon pump, pump time, clamp time, pH at extubation time, and PaO2 at extubation time. Conclusion: Patients who required reintubation had the worst respiratory function.

The purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a Post Thrombotic Syndrome (PTS). Methods: During 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous thrombosis. 16 patients were reexamined after a 5-year follow-up. At follow-up, the patency of venous segments as well as the development of reflux was investigated by duplex-ultrasound. Furthermore, clinical signs and symptoms of PTS in patients were recorded. Results: Clinical pulmonary emboli did not occur in the perioperative period. Two patients died because of disseminated metastatic cancer and another after massive retroperitoneal bleeding due to anticoagulation therapy. In a 5-year follow up, 31% had valvular reflux. Venous patency rate was 75%. The rate of PTS was 37.5% without the severe form of PTS. Patients did not have healed, healing, and/or active venous ulcer. Conclusion: It is thought that vein patency and valvular function were relatively restored, and PTS was prevented after surgical thrombectomy.

To overcome this complication we decided to perform an end-to-end anastomosis and compare it with end-to-side Roux-en-Y esophagojejunostomy. Methods: In this prospective study, between 1998 and 2005, 71 patients with a diagnosis of gastric adenocarcinoma underwent total gastrectomy. Standard esophagojejunostomy with an end-to-side fashion was performed in 41 patients and compared with our recommended technique of end-to-end esophagojejunostomy in 30 patients. Results: This study showed that esophagojejunostomy with an end-to-end fashion has a low incidence of postoperative dysphagia (33.3%), whereas in those with an endto- side anastomosis the rate of ysphagia is very high (83%). Conclusion: A Roux-en-Y esophagojejunostomy with an end-to-end anastomosis has a low incidence of postoperative dysphagia and we strongly recommend using this technique.}, Keywords = {total gastrectomy, alimentary tract reconstruction, esophagojejunostomy, dysphagia}, volume = {21}, Number = {3}, pages = {151-153}, publisher = {Iran University of Medical Sciences}, url = {http://mjiri.iums.ac.ir/article-1-328-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-328-en.pdf}, journal = {Medical Journal of The Islamic Republic of Iran (MJIRI)}, issn = {1016-1430}, eissn = {2251-6840}, year = {2007} } @article{ author = {Azarpazhooh, MR. and Shoeibi, A. and Soroush, MR. and Khateri, S. and Mousavi, SJ. and Modirian, E.}, title = {Can mustard gas induce late onset polyneuropathy?}, abstract ={ Abstract Background: Mustard gas, lethal in high doses, affects multiple organs such as skin, eye and respiratory system. We studied the development of late onset mustardinduced polyneuropathy among chemically wounded Iranian veterans. Methods: In this descriptive study, 100 chemically wounded Iranian veterans with severe eye involvement were examined for any signs and symptoms of polyneuropathy by an internist. 20 patients were suspected to have neurological symptoms or signs. These patients were examined by a neurologist again. 13 showed abnormal neurological symptoms. Electrodiagnostic exams were performed for this group by another physician. Results: 13 veterans had abnormal neurological exam results with prominent sensory signs and symptoms in almost all of them. Brisk deep tendon reflexes were found in 3 cases. Electrodiagnostic studies were compatible with axonal type distal sensory polyneuropathy in 6 subjects. Conclusion: To the best of our knowledge, this is the first report of late onset polyneuropathy among chemically-wounded victims who were exposed to mustard gas.

About 7% of the population have thyroglossal duct remnants. Clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. Thyroglossal duct cysts may rarely develop carcinomas (1-1.6 %) but tend to occur more in adults than children. Methods: We retrospectively reviewed all cases of TDC carcinoma surgically treated during a 15-years period at Ahwaz Emam Hospital center. Results: Three patients (two female and one male patient), who were 23 to 46 years old (mean 38 yr.) were identified. The frequency of TDC carcinoma among surgically removed TDC cysts was 0.7%. Amidline upper neck mass was the initial symptom in all patients. The diagnosis of cancer was made after the Sistrunk’s procedure in all three cases. All patients had papillary carcinoma. Thyroid involvement was noted in one case. One patient had near-total thyroidectomy, and two received postoperative radioactive iodine. After a mean follow-up of 11 years (range: 1 to 15 yr.), no patient had a documented local recurrence or distant metastatic involvement, and no tumor-associated mortality was observed. Conclusion: Although development of a papillary thyroid carcinoma from thyroglossal cyst is very rare, it should be born in the mind of the surgeon and the pathologist that this possibility exists and the ductal wall should be examined elaborately. }, Keywords = {thyroglossal duct, cyst, papillary carcinoma, neck surgery}, volume = {21}, Number = {3}, pages = {131-134}, publisher = {Iran University of Medical Sciences}, url = {http://mjiri.iums.ac.ir/article-1-324-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-324-en.pdf}, journal = {Medical Journal of The Islamic Republic of Iran (MJIRI)}, issn = {1016-1430}, eissn = {2251-6840}, year = {2007} } @article{ author = {Motamed, S and FadaeeNaeeni, A}, title = {Extended RetroauricularTemporal Flap with Conchal Cartilage for Alar or Columellar Reconstruction}, abstract ={ Abstract Background: The retroauricular-temporal or Washio flap has been introduced for reconstruction of partial nose and cheek defects, and has many advantages.
