A total of 53 patients infected with Taenia solium were treated with praziquantel in two different dose levels. Twenty-six cases were treated with praziquantel in a single oral dose of 5 mg/kg body weight. All cases except one were completely cured. The cure rate was 96.2 per cent. The other 27 cases were treated with a single dose of 10 mg/kg body weight. All cases were completely cured and revealed a cure rate of 100 per cent. Side effects were mild and transient. About half of the cases complained of a mild abdominal pain. Soft stool or diarrhea and dizziness were observed in some cases. Tests on clinical hematology, serum biochemistry and urinalysis were performed immediately before and one day after treatment in all cases. There were no significant abnormalities detected in these tests.

PURPOSE: To compare the results of cataract surgery between continuous mode and WhiteStar mode the latter is known to induce less heat production in the anterior chamber METHODS: The patients were recruited prospectively since May 2003. They were consecutively assigned to the continuous mode group and the WhiteStar mode group according to preoperative lens color grading in order to equally distribute the lens color grading in both groups. Ultrasound time, operating time, and loss of endothelial cells were evaluated. RESULTS: There was a positive correlation between lens color and ultrasound time and between lens color and operating time (p<0.01). There was no significant difference between the two groups in ultrasound time, operating time or loss of endothelial cells. CONCLUSIONS: There was no remarkable advantage in cataract surgery using WhiteStar mode compared with using conventional continuous mode.

The authors analysed statically 420 Cases of the ocular trauma among 35,460 patients who visited to the emergency department, from Jul. 1995 to Jun. 1996. Ocular trauma is one of the commonest causes of eye diseases and blindness, but its patterns and incidences are variable according to the environment. A large number of patients can be readily treated in the emergency department. Prevention is, of course, the best management, but when an ocular injury occurs, proper emergency treatment can often prevent permanent damage.

PURPOSE: The purpose of this study is to evaluate the characteristics of parotid gland tumors to help in the differentiation between benign and malignant lesions. MATERIAL AND METHODS: The CT findings of 22 patients with surgically proven parotid gland tumors were reviewed. Analysis was focused on the density and margin characteristics of the tumors, and the relationahip between the tumor and surrounding structures. RESULTS: Those tumors were pleomorphic adenoma (n=8), Warthin's tumor (n=5), basal cell adenoma (n=l), lipoma (n=l), dermold cyst (n=l), adenold cystic carcinoma (n=2), mucoepidermoid carcinoma (n=l), epidermold carcinoma (n=l), and carcinoma in pleomorphic adenoma (n=l). Most of benign and malignant tumors were heterogeneous in denstiy on contrast enhanced CT scans. In 5 of 6 malignant cases, the tumors had irregular or ill-defined margin and a tendancy to involve or cross the superficial layer of deep cervical fascia with obliteration of subcutaneous fat. Two malignant tumors invaded surrounding structures. CONCLUSION: Although the heterogeneous density of tumor is not a specific finding for malignancy at CT, following findings, such as, irregular or blurred margin of the lesion, the involvement of fascial plane, and the infiltration of surrounding structures may suggest the possibility of malignant parotid tumor.

Bone marrow aspirates concentrate (BMAC) transplantation is a well-known technique for cartilage regeneration with good clinical outcomes for symptoms in patients with osteoarthritis (OA). Magnetic resonance imaging (MRI) has an important role in evaluating the degree of cartilage repair in cartilage regeneration therapy instead of a second assessment via an arthroscopy. We experienced a case of hypertrophic regeneration of the cartilage and a presumed simultaneous regeneration of the posterior horn of the lateral meniscus after BMAC transplantation for a cartilage defect at the lateral tibial and femoral condyle. This report provides the details of a case of an unusual treatment response after a BMAC transplant. This report is the first of its kind to demonstrate a MR image that displays the simultaneous regeneration of the cartilage and meniscus with a differentiation ability of the mesenchymal stem cell to the desired cell lineage.

PURPOSE: To investigate the effects of angiotensin II inhibition on the epithelial to mesenchymal transition (EMT) in the developing kidney, we tested the expression of EMT markers and nestin in angiotensin converting enzyme (ACE) inhibitor-treated kidneys. METHODS: Newborn rat pups were treated with enalapril (30 mg/kg/d) or a vehicle for 7 days. Immunohistochemistry for the expression of alpha-smooth muscle actin (SMA), E-cadherin, vimentin, and nestin were performed. The number of positively-stained cells was determined under 100 magnification in 10 random fields. RESULTS: In the enalapril-treated group, alphaSMA-positive cells were strongly expressed in the dilated tubular epithelial cells. The number of alphaSMA-positive cells in the enalapril-treated group increased in both the renal cortex and medulla, compared to the control group (P<0.05). The expression of E-cadherin-positive cells was dramatically reduced in the cortical and medullary tubular epithelial cells in the enalapril-treated group (P<0.05). The number of vimentin- and nestin-positive cells in the cortex was not different in comparisons between the two groups; however, their expression increased in the medullary tubulointerstitial cells in the enalapril-treated group (P<0.05). CONCLUSION: Our results show that ACE inhibition in the developing kidney increases the renal EMT by up-regulatingalphaSMA and down-regulating E-cadherin. Enalapril treatment was associated with increased expression of vimentin and nestin in the renal medulla, suggesting that renal medullary changes during the EMT might be more prominent, and ACE inhibition might differentially modulate the expression of EMT markers in the developing rat kidney.

PURPOSE: Adequate lymph node analysis is critical for appropriate staging in colorectal cancer. The aim of this study is to determine whether 12 or more nodes recovered in stage III rectal cancer results in improved oncologic outcomes. METHODS: Two hundred and forty-eight patients with stage III rectal cancer from 1995 through 2004 were reviewed. They were categorized into 2 subgroups by the number of nodes retrieved (<12 and > or =12), and oncologic outcomes in terms of 5-year overall and disease-free survival were analyzed for all patients, patients with American Joint Committee on Cancer (AJCC) N1 disease (N=145), and those with AJCC N2 (N=103). RESULTS: Five-year overall and disease-free survival was 79.0% and 58.4%, respectively. There was no significant difference in clincopathologic features between <12 retrieval group and > or =12 group. Although there was significant difference in overall survival and disease-free survival between the number (<12 and > or =12) of lymph nodes removed in N2 disease (P=0.043; P=0.022) in univariate analysis, the total number of lymph nodes retrieved was not a prognostic factor affecting survival in multivariate analysis. The N2 stage and lateral margin involvement were prognostic factors affecting survival in multivariate analysis. CONCLUSION: This study showed that the total number of lymph nodes analyzed for stage III rectal cancer is not a prognostic factor on overall or disease-free survival in multivariate analysis.
