OBJECTIVE: To investigate the shoulder disease patterns for the table-tennis (TT) and archery (AR) wheelchair athletes via ultrasonographic evaluations. METHODS: A total of 35 wheelchair athletes were enrolled, made up of groups of TT (n=19) and AR (n=16) athletes. They were all paraplegic patients and were investigated for their wheelchair usage duration, careers as sports players, weekly training times, the Wheelchair User's Shoulder Pain Index (WUSPI) scores and ultrasonographic evaluation. Shoulders were divided into playing arm of TT, non-playing arm of TT, bow-arm of AR, and draw arm of AR athletes. Shoulder diseases were classified into five entities of subscapularis tendinopathy, supraspinatus tendinopathy, infraspinatus tendinopathy, biceps long head tendinopathy, and subacromial-subdeltoid bursitis. The pattern of shoulder diseases were compared between the two groups using the Mann-Whitney and the chi-square tests RESULTS: WSUPI did not significantly correlate with age, wheelchair usage duration, career as players or weekly training times for all the wheelchair athletes. For the non-playing arm of TT athletes, there was a high percentage of subscapularis (45.5%) and supraspinatus (40.9%) tendinopathy. The percentage of subacromial-subdeltoid bursitis showed a tendency to be present in the playing arm of TT athletes (20.0%) compared with their non-playing arm (4.5%), even though this was not statistically significant. Biceps long head tendinopathy was the most common disease of the shoulder in the draw arm of AR athletes, and the difference was significant when compared to the non-playing arm of TT athletes (p<0.05). CONCLUSION: There was a high percentage of subscapularis and supraspinatus tendinopathy cases for the non-playing arm of TT wheelchair athletes, and a high percentage of biceps long head tendinopathy for the draw arm for the AR wheelchair athletes. Consideration of the biomechanical properties of each sport may be needed to tailor specific training for wheelchair athletes.

PURPOSE: Granulocyte-colony stimulating factor(G-CSF) and granulocyte macrophage-colony stimulating factor(GM-CSF) are principal cytokines in granulopoiesis and their physiologic effects are mediated through binding to specific cell surface receptors. Although it is known that the level of serum G-CSF and GM-CSF, and presentation of the receptors are increased in infectious diseases, there have been no studies to find the correlation between the granulopoiesis and leukocytosis. This study was designed to measure G-CSF and GM-CSF in leukocytosis and in control and to demonstrate the possible pathogenesis of granulopoiesis in leukocytosis using quantitative analysis of G- CSF, GM-CSF and their CSFr. METHODS: The plasma levels of G-CSF, GM-CSF of 13 children without leukocytosis and 14 children with leukocytosis were measured. Counts of cell surface G-CSFr and GM-CSFr were measured by combining anti G-CSFr and anti GM-CSFr monoclonal antibodies to their respective receptors by using quantitative flow cytometric assay. RESULTS: There was no significant difference betweeen the plasma concentration of G-CSF and GM-CSF in acute leukocytosis and in the control group. However, levels of G-CSFr in acute leukocytosis decreased significantly compared to the control(P=0.012) and the levels of GM-CSFr in both groups revealed no significant difference. CONCLUSION: Increase in the number of leukocyte in leukocytosis was mediated by increasing the number of neutrophil, and increased plasma concentration of G-CSF may be the cause of neutrophilia. But GM-CSF did not have any influence on leukocytosis.

BACKGROUND/AIMS: Pyloric exclusion has been recommended in patients with severe injury to the pancreas and duodenum. METHODS: A retrospective case review of 8 patients treated with pyloric exclusion following pancreaticoduodenal injury from March 1994 to May 2002 in Department of Surgery, the Catholic University of Korea, Daejeon St. Mary's Hospital. RESULTS: The age range of the patients was from 8 to 31 years. Most of the etiolgy (n=7) was the blunt abdominal trauma and one case due to the iatrogenic injury from the therapeutic endoscopic retrograde cholangiopancretography. The time interval between the injury and the operation varied from 3 to 48 hours. The most common postoperative complication was wound infection (n=8). We found the other complications such as intraabdominal abscess (n=3), pneumonia (n=3), but the complications were treated successfully with conservative measures. There was no mortality cases in these patients. The duration of admission was delayed in the cases of concomitant injury (64 vs 46 days). All patients above 16 years old (n=7) were supported with parenteral nutritional fluid via central intravenous route (mean 32 days). We could not find the spontaneous opening of the pyloric closure at least 4 patients in postoperative 3 months but there was no major complication according to the sustained gastrojejunostomy. CONCLUSION: Pyloric exclusion appears to offer a satisfactory option for the treatment of the severe pancreaticoduodenal injury with minor complication. Do you have any comments about the spontaneous opening of the pyloric closure?

A 36-year-old previously healthy woman developed diplopia and right-sided ptosis. Neurological examinations were normal except for palsy in the right third cranial nerve with pupil involvement. CT and MRI revealed a cavernous hemangioma with recent bleeding in the right midbrain. This case indicates that midbrain cavernous hemangioma can be a rare cause of isolated pupil involving palsy of the third cranial nerve.

PURPOSE: To determine the relationship between changes in the tear film according to the classification of diabetic retinopathy in patients with diabetes. METHODS: A total of 117 newly detected diabetic patients were included in this study. The classification of diabetic retinopathy was performed based on the Early Treatment Diabetic Retinopathy Study (ETDRS). The duration of diabetes and HbA1c were also investigated in patients who had undergone panretinal photocoagulation or insulin treatment. To examine the tear film function, we performed the tear break-up time test, the Schirmer I test, and the diagnostic fluorescein staining test of the ocular surface. The Cochet-Bonnet esthesiometer was also employed to examine the corneal sensitivity. RESULTS: As the severity of diabetic retinopathy progressed, the degree of ocular surface fluorescein staining increased significantly. There was no relationship between the duration of diabetes and the results of the tear film function test. Patients who had high blood HgA1c levels showed significant increases in tear break-up time and degree of ocular surface fluorescein staining. The patients who had undergone panretinal photocoagulation showed significant differences in tear break-up time and degree of ocular surface fluorescein staining. CONCLUSIONS: The diabetic patients with progressed diabetic retinopathy, uncontrolled blood HgA1c levels and who had previously undergone panretinal photocoagulation should be managed more carefully since those patients are more susceptible to ocular surface disorder with aggravation of tear film function.

Eczema herpeticum is a widespread Herpes simplex virus(HSV) infection, which usually develops in patients with atopic dermatitis. Because pruritus in patients with atopic dermatits leads them to scratch their bodies, it causes the dissemination of Herpes simplex virus. A delay in diagnosing this condition may result in intense and rapid spread of the cutaneous lesions. We report a patient who underwent a prolonged friction with a rough nylon towel while bathing and developed eczema herpeticum. We suspect a bath with a rough nylon towel as a possible route of spread.

A material for ridge preservation should have dimensional stability to resist bio-degradation. This study was designed to compare bio-degradation of ridge preservation materials. Collagen plug was used as a positive control. Untreated, ethanol-treated, and 4-hexylresorcinol (4HR)-treated silk plugs were used for the experimental group. Each material underwent a scanning electron microscopic exam and a Fourier transform infrared (FT-IR) spectroscopic exam. Bio-degradation was evaluated by analyzing cylindrical bony defects in rabbit tibias. There were no prominent differences in microstructure among the silk plug groups. FT-IR exam demonstrated that the ethanol- and 4HR-treated silk plug groups had enhanced β-sheet structure. All silk plug groups exhibited significantly higher residual graft than the collagen plug group 4 weeks postoperative (p<0.05). In conclusion, silk fibroin-based ridge preservation material was less bio-degradable than a collagen plug until at least 4 weeks after grafting.
