PURPOSE: The single-radius design of the knee implant was introduced to improve the results of total knee arthroplasty (TKA) by reducing maximum extensor forces, and it also represents more physiologic quadriceps force pattern, which could have a positive effect on knee function after TKA. We studied mid-term results of single-radius designed cruciate retaining (CR) TKA. MATERIALS AND METHODS: We analyzed the functional improvement and radiological osteolytic pattern after TKA using the single-radius Scorpio CR prosthesis. TKA was performed on 102 knees. The mean follow-up period was 73.8 months. For clinical assessment, the range of motion (ROM), Harris hip score, and functional outcome score were obtained preoperatively and at last follow-up. RESULTS: The average ROM was 100.2degrees preoperatively and 121.7degrees at last follow-up. The average knee score was 59.2 points preoperatively and 92.9 points at last follow-up. The average functional outcome score was improved from 51.9 points preoperatively to 85.4 points at last follow-up. Radiolucency was observed in four knees but all were non-progressive lesions smaller than 2 mm. CONCLUSIONS: The clinical outcome of TKA using the single-radius CR prosthesis was good during the mid-term follow-up and the incidence of osteolysis was very rare.

OBJECTIVE: To evaluate the diagnostic value of computed tomography-myelography (CTM) compared to that of magnetic resonance imaging (MRI) in patients with lumbar radiculopathy. METHODS: The study included 91 patients presenting with radicular leg pain caused by herniated nucleus pulposus or lateral recess stenosis in the lumbar spine. The degree of nerve root compression on MRI and CTM was classified into four grades. The results of each imaging modality as assessed by two different observers were compared. Visual analog scale score for pain and electromyography result were the clinical parameters used to evaluate the relationships between clinical features and nerve root compression grades on both MRI and CTM. These relationships were quantified by calculating the receiver-operating characteristic curves, and the degree of relationship was compared between MRI and CTM. RESULTS: McNemar's test revealed that the two diagnostic modalities did not show diagnostic concurrence (p<0.0001). Electromyography results did not correlate with grades on either MRI or CTM. The visual analog pain scale score results were correlated better with changes of the grades on CTM than those on MRI (p=0.0007). CONCLUSION: The present study demonstrates that CTM could better define the pathology of degenerative lumbar spine diseases with radiculopathy than MRI. CTM can be considered as a useful confirmative diagnostic tool when the exact cause of radicular pain in a patient with lumbar radiculopathy cannot be identified by using MRI. However, the invasiveness and potential complications of CTM are still considered to be pending questions to settle.

Cerebral venous sinus thrombosis and acute renal failure are well known cornplications of paroxysmal nocturnal hemoglobinuria(PNH). 53 year old rnan was admitted to the hospital because of headache and gerleralized convulsion. Contrast enharlced CT scan revealed empty delta sign in superior sagital sinus and acute renal failure developed within 2 weeks of admissiorL The diagnosis of PNH depended on positive HAM test and low leukocyte alkaline phosphatase(LAP). The prognosis was relativley good on the treatrnent with anticoagulant, anticonvulsant, antiplatelets and steroid.

BACKGROUND: Thyroid status in uremia is still inconclusive due to the complexicity of the system. No single pathogenetic event may explain the thyroid function abnormalities in end stage renal disease (ESRD). Defects at all levels of the hypothalamic-pituitary-thyroid axis have been identified. Regarding the thyroid dysfunction in ESRD it is well recognized that the TSH response to TRH is blunted and serum concentrations of thyroid hormones are decreased in patients with ESRD. Whether or not on maintenance hemodialysis. Restoration of renal function with renal transplantation resulted in normalization of all parameters of thyroid function with exception of blunted TSH response to TRH. We evaluated the long-term changes of the thyroid function in 10 patients to know whether the thyroid function and the hypothalamo-pituitary axis were improved with the recovery of the renal function under maintenance low-dosage steroid administration after renal transplantation. METHODS: These tests were performed during the morning in the fasting state in 10 ESRD patients before, 1 month and 6 years after renal transplantation (RT). Thyroid function tests. Serum T3, T4 were measured by RIA kit and serum TSH was measured by IRMA kit. TRH stimulation test. Serum blood samples were obtained 0, 30, 60, 90, 120 min after TRH (400microgram) administration. Statistical analysis. All grouped data were expressed as mean+/-SD. Student t-test was used to assess the statistical difference between any two means. RESULTS: 1) The mean basal level of serum T3 was reduced in ESRD patients (53.6+/-33.2ng/dL) and increased to the low normal level 1 month after RT (87.8+/-25.4ng/dL), improved to the normal level 6 years after RT (116.3+/-28.8ng/dL). 2) The mean basal level of T4 was within normal range before RT (5.9+/-1.1microgram/dL), after 1 month (6.2+/-1.2microgram/dL) and after 6 years (6.5+/-1.4microgram/dL) of RT. 3) The mean basal level of TSH was within normal range before RT (2.0+/-1.2microU/mL), after 1 month (1.1+/-0.7microU/mL), and after 6 years (0.7+/-0.5microU/mL) of RT. Rut the mean TSH level of 6 years of RT was significantly decreased within the normal range. 4) In ESRD the TSH response to TRH was blunted, had a diminished peak and delayed fall before RT. After 1 month of RT, the TSH response to TRH was persistently blunted, however showed more rapid fall of TSH. After 6 years of RT, the TSH response to TRH normalized, but the absolute level of TSH and the peak level of TSH to TRH were less than before and after 1 month of RT. CONCLUSIONS: The abnormalities of thyroid hormones in uremic patients were improved partially after 1 month of RT and almost completely after 6 years of RT. But the level of T3H and the peak level of TSH to TRH were low within normal range, these results may be a direct consequence of low-dosage and long-term glucorcorticoid administration.

Hydroxyurea is an effective treatment for a variety of myeloproliferative disodrers. A distinct cutaneous reaction to long-term administration of hydroxyurea has been characterized and designated hydroxyurea dermopathy. Epidermal dysmaturation refers to histologic changes that may be observed in the epidermis after any significant cytoreductive therapy. We report a patient with hydroxyurea-induced dermatomyositis-like eruption showing epidermal dysmaturation who developed an erythematous scaly patches on the dorsal aspects of the hands while on long-term administration of hydroxyurea for chronic myelogenous leukemia.

Chlamydia trachomatis is known as a major causative microorganism in non-gonococcal urethritis(NGU) in men. We examined two kinds of specimens simultaneously, endourethral swab and urine, in each patient to determine the reliability of these two different specimens for the detection of the Chlamydia trachomatis antigen in male NGU patients using ELISA method. Tota1 273 patients entered this study were divided into two groups according to sampling order of urine and endourethral swab. In group A(141 patients), we took endourethral swab first, then first portion of voided urine was caught. In group B(132 patients), endourethral swab was performed after urine sampling. Twenty five out of 273 patients(9.2%) showed Chlamydia trachomatis antigen positive in endourethral swab sample and 1 out of 273 patients(0.4%) was positive in urine sample. There was no significant difference of antigen positive rate of endourethral swab examination between group A and group B. Our data suggest that examination of endourethral swab is more reliable method for the detection of the Chlamydia trachomatis antigen than urine examination in male NGU patient.

In 1961, Cornes first introduced the term multiple lymphomatous polyposis(MLP), and since then, this very raredisease has been considered as a malignant lymphoma originating in the mantle zone of gastrointestinal lymphoidtissue. MLP presents with a 0.5-2.0cm sized polypoid tumor, which affects long segments of the alimentary tractand frequently invades the mesenteric lymph nodes. It often consists of a dominant mass rather than polyps. Wedescribe three cases of endoscopically proven multiple lymphomatous polyposis, and include a review of theliterature. In differentiating multiple lymphomatous polyposis and other types of multiple polyposis in thegastrointestinal tract, the following features are helpful : the smooth surface of polyps, which is similar to agem seen during a barium examination ; the typical appearance of a gastric submucosal tumor and hypertrophiedgastric mucosal folds in UGI; the presence of enlarged lymph nodes, as seen on abdominal CT scanning.
