Between Feb. 1992 and Apr, 1995, the authors have performed arthroscopic abrasion arthroplasty in 78 knees of 76 patients with degenerative osteoarthritis. The followup period was between 24 and 58 months, with on an average of 41 months. All patients had Zarins grade IV articular cartilage change. The results were as follows. 1. Of the total 78 knees, results were excellent in 25(32%), good in 33(42A), fair in 12(17%), poor in 8(10%) knees respectively. 2, The best results were obtained patellofemoral abrasion arthroplasty. 3. The poor results were obtained in patients with the both femoral condyle, lesion. 4. The results were much better in young age group (below 40 years). Aroscopic abrasion arthroplasty is not a curative but palliative method. But it could be an appealing altemative to total knee arthroplasty or high tibial osteotomy or can be performed postoperated after these reconstructive proeedures.

Systemic lupus erythematosus is a connective tissue disease which can affect every organ system. Neurologic abnormalities are common, occuring in approximately half of all patients at some time during the course of their illness. But symptoms of nervous system as the sole presenting symptoms occur in less than 1% of lupus patients. In patients initially presenting with neurologic symptoms and signs, differential diagnosis is difficult and sometimes it may be misdiagnosed. Therefore extensive laboratory investigations should be carried out in all patients with unusual neurological symptoms, since early diagnosis of lupus can help in providing effective treatment. We report a patient with systemic lupus erythematosus who presented with dysarthria and dysphagia resembling multiple sclerosis.

Malignant transformation of benign cystic teratomas of the ovary is rare, with an incidence rate of 1-3%. The most common malignancy associated with benign cystic teratoma of the ovary is squamous cell carcinoma, which represents 90% of malignant transformations, followed by adenocarcinoma and carcinoid. Primary malignant neuroectodermal tumor in a mature cystic teratoma is extremely rare and microscopically can be subclassified as differentiated, primitive, and anaplatic. We experienced a case of primitive neuroectodermal tumor (PNET) associated with mature cystic teratoma of the ovary in a 11-year-old girl. Grossly, the ovary was a unilocular cyst which contained sebum material and disclosed several large, yellow to gray-tan polypoid excresences attached to the inner cystic wall. Except a large, fish-flesh, soft mass, the other polypoid masses were covered with sebum and contained small pieces of cartilage and tooth, and microscopically represented as mature teratoma. The large, fish-flesh, soft mass disclosed sheets and lobules of closely packed small cells with thin fibrovascular septa, which frequently replacing and encroaching the mature cystic teratoma. The small tumor cells were uniform and made up of round to oval nuclei with coarse chromatin and prominent nucleoli, very similar to those of PNET of the central nervous system.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.

PURPOSE: The objective of this study was to assess the usefulness of a unilateral x-ray of the kidney, ureter and bladder (hemi-KUB), in the place of a full-KUB, in the follow-up of patients treated with extracorporeal shock wave lithotripsy (ESWL), and thereby reduce the radiation exposure for patients. MATERIALS AND METHODS: A total of 111 patients, who underwent ESWL, between March 2000 and July 2002, were enrolled onto the study. Patients with bilateral stones, or who had changed to another treatment model, were excluded. During the follow-up to the ESWL, we used the hemi-KUB method for the collimation of the radiation field. The numbers of hemi-KUBs during the treatment were recorded. The reductions in the exposure to the radiation dose, per patient, were calculated and analyzed according to the sizes and shapes of the stones. The typical doses were: for IVU (6 films), 2.5mSv; full-KUB film, 0.42mSv; and a hemi-KUB film, 0.21mSv. RESULTS: The total reduction in the doses of radiation exposure was 114.45mSv. The radiation doses, per patient, were reduced by a mean of 1.03+/-0.58mSv. The reduction in the dose of radiation exposure correlated well with the stone size (r=0.7082, p<0.05). The mean number of hemi-KUBs (mean reduction dose of radiation exposure), according to the stone size groups: these being 5-9, 10-19 and +/-20mm, were 3.82+/-1.76 (0.80+/-0.37), 6.52+/-2.10 (1.37+/-0.44) and 11.00+/-3.85 (2.31+/-0.81)mSv, respectively (p<0.05). Also, the mean number of hemi-KUBs (mean reduction dose of radiation exposure), according to the stone shapes, typed into I (less organized or lacy), IIa (spiculated), IIb (mulberry), III (round or ovoid) and IV (struvite or staghorn), were 2.77+/-0.85 (0.58+/-0.18), 4.48+/-1.86 (0.94+/-0.39), 4.83+/-1.43 (1.01+/-0.30), 7.54+/-1.36 (1.58+/-0.29) and 8.75+/-3.72 (1.84+/-0.78)mSv, respectively (p<0.05). Using the receiver operating characteristic curve, the cut-off value, of a stone size that could be used to determine the risk group whose radiation exposure exceeding 5mSv (personal permissible dose/year), was 23.52mm, but when using a full-KUB this was 7.97mm. CONCLUSIONS: The use of hemi-KUB is a simple and easy method to reduce the radiation exposure in the follow-up of an ESWL, especially in patients with stones larger than 7.97mm in size, with a round-ovoid or staghorn shape.
