PURPOSE: We report clinical and radiologic outcomes after metacarpal extension osteotomy for mild osteoarthritis of the thumb carpometacarpal joint. MATERIALS AND METHODS: From 1999 to 2008, 11 patients were diagnosed with mild thumb carpometacarpal arthritis (Eaton stage I, II), and extension osteotomies were performed. Of these, seven patients with at least 6 years follow-up were analyzed retrospectively. Male to female ratio was 2:5, and mean age at time of surgery was 38.9 years old. Symptom onset period was a mean of 11.2 months. Two patients were I, and five patients were II in Eaton stage. Preoperative visual analogue scale (VAS) and disabilities of the arm, shoulder and hand scale (DASH) scores were 3.7 points (3-4 points), and 40.1 points (32-51 points). Radial abduction was 38.5degrees (30degrees-45degrees), and volar abduction was 42.1degrees (40degrees-45degrees). Grip strengths and pinch powers, compared with the normal contralateral side were 82% (64%-90%) and 72% (40%-100%), respectively. RESULTS: The mean follow-up period was 8.5 years, and all patients except one maintained their occupational activity during the follow-up period. Final VAS and DASH scores were 0.7 points (0-2 points) and 11.7 points (8-16 points), respectively, and were statistically significant. Volar abduction, grip strengths, and pinch power were improved to 45degrees (40degrees-50degrees), 92.3% (73%-117%), and 94.4% (75%-117%) with statistical significances. In five patients, Eaton stages did not change, and two patients advanced to the next stage (stage I to II in one patient, stage II to III in one patient). CONCLUSION: Among the various treatment options for mild thumb carpometacarpal arthritis, metacarpal extension osteotomy may be considered as an effective treatment.

BACKGROUND: The inhibitory effects of nitric oxide(NO) on platelet adhesion and vascular smooth muscle cell(VSMC) proliferation may have a possible role inhibiting development of neointima following balloon catheter induced injury. We tested the hypothesis that L-arginine, the precursor of NO, would attenuate neointima formation following balloon catheter induced injury via regulation of antagonistic balance between proliferation and apoptosis of VSMC. METHODS: Adult, male Sprague-Dawley rats(300 to 400g) were anesthetized with ketamine (100mg/kg intraperitoneally). The left common and external carotid artery were exposed. For endothelial denudation, 2mm angioplasty catheter was introduced through the left external carotid artery into the left common carotid artery. The catheter was inflated at I atm. and withdrawn three times. Animals were randomized to receive 2.25% L-arginine in their drinking water(n=14) or placebo(n=16) from 2 days prior to and 9 days following denudation. VSMC proliferation was quantified by immunohistochemical staining with an antibody to the proliferating cell nuclear antigen(PCNA). The cells undergoing apoptosis were identified by terminal nucleotidyl transferase-mediated nick end labeling(TUNEL) method and morphologic changes by computerized planimetry and transmission electron microscopy. RESULTS: 1) The neointimal area in injured arteries were significantly reduced in L-arginine supplemented animals compared with placebo group(p<0.05). 2) L-arginine administration significantly reduced the number of PCNA positive cells in neointima when compared with placebo at 9 days(p<0.05). 3) Positive TUNEL cells were not influenced by L-arginine supplementation. 4) On transmission electron microscopy, there were no cells showing characteristics of apoptosis in neointima. CONCLUSION: These results suggested that the inhibitory effect of L-arginine on neointima formation is due to reduced VSMC proliferation, but is not due to increased VSMC apoptosis at the early time period after initmal injur .

Transient synovitis of the hip is non-specific inflammation and self limited condition, which is most common cause of painful limping in children under 10 years of age. Ultrasonography presents some merits, simple, rapid, non-invasive, low cost, repetitive to assess soft structures in and around the hip joint compared to other diagnostic methods. We prospectively studied 32 cases of unilateral transient synovitis at OPD from Jan. 1988 to Oct. 1989 using 5-7.5 MH, probe ultrasonography. 2-times serial check up in symptomatic and asymptomatic stage about capsule thickness and bone-capsule distance in 3 different positions of the both hips were performed for comparision. The following results were obtained; 1. Boys were 25 cases (78%) and 26 cases (83%) were between 3 and 7 years old of age. 2. Bone-capsule distance in ultrasonography revealed abnormal increase in 72%. 3. External rotation position showed wider bone-capsule distance than other position. 4. Capsule thickness was 3.3mm in diseased and 3.0mm in sound, 0.3mm decrease after treatment. 5. Bone-capsule distance was 4.5mm in symptomatic stage, 2.7mm in asymptomatic stage, 1.8mm decrease after treatment in averge.

Here, we report a case of newly diagnosed diabetes, with concurrent pancreatic cancer manifested as hyperglycemic crisis, and aggravated by urinary tract infection. We summarize the initial clinical manifestations and pertinent laboratory, radiologic, and clinical findings in an elderly patient with hyperglycemic emergency. A review of the documents involving pancreatic tumors and hyperglycemic hyperosmolar state, which is an acute complication of diabetes mellitus, is presented. In the absence of other identifiable conditions, it is reasonable to speculate that some factor (or factors) produced by the tumor had a role in the metabolic decompensation. In addition, this discussion should be more carefully considered in the aged people group.

PURPOSE: The purpose of this study was to establish optimal imaging acquisition conditions for the GE Advance(TM) PET imaging system by performing the acceptance tests designed by National Electrical Manufacturers Association (NEMA) protocol and General Electric Medical Systems (GEMS) test procedures. MATERIALS AND METHODS: Performance tests were carried out with 18FDG radioactivity source and phantoms by using a standard acquisition mode. Transaxial resolution and scatter fraction tests were performed with a line source and axial resolution with a point source, respectively. A cylindrical phantom made of polymethylmethacrylate (PMMA) was used to measure sensitivity, count rate losses and randoms, uniformity correction, and attenuation inserts were added to measure remaining tests. The test results were acquired in a diagnostic acquisition mode and analyzed mainly on high sensitivity mode. RESULTS: Transaxial resolution and axial resolution were measured as average of 4.65 mm and 3.98 mm at 0 cm, and 6.02 mm and 6.71 mm at 20 cm on high sensitivity mode, respectively. Average scatter fraction was 9.87%, and sensitivity was 225.8 kcps/micronCi/cc of trues. Activity at 50% deadtime was 4.6 Ci/cc, and the error of count rate correction at that activity was from 1.49% to 3.83%. Average nonuniformity for total slice was 8.37%. The accuracy of scatter correction was -0.95%. The accuracies of attenuation correction were 5.68% for air, 0.04% for water and -6.51% for polytetrafluoroethylene (PTFE). CONCLUSION: The results satisfied most acceptance criteria, indicating that the GE AdvanceTM PET system can be optimally used for clinical applications.

The use of bacteria in the treatment of cancer has a long and interesting history. The use of live bacteria in this way however has a number of potential problems including toxicity. Purified low molecular weight bacterial proteins have therefore been tested as anticancer agents to avoid such complications. Oral cancer is a widely occurring disease around the world and these lesions are typically very resistant to anticancer agents. In our present study we investigated the effects of purified recombinant azurin from Pseudomonas (P.) aeruginosa against YD-9 (p53-positive) human oral squamous carcinoma cells. Azurin showed cytotoxic effects against these cells in a dose dependent manner. The cell death accompanied by this treatment was found to be characterized by chromatin condensation and apoptotic bodies. Azurin treatment was further found to increase the expression of p53 The stabilization of p53 and induction of apoptosis in YD-9 cells by azurin suggests that it has potentially very strong anticancer properties in oral squamous carcinoma.
