2.Outcomes of Epiduroscopy Using Less Than 50 ml of Normal Saline in Low Back and Lower Extremity Pain Patients.
Korean Journal of Anesthesiology 1999;37(5):854-858
BACKGROUND: Epidural adhesion can cause pain from compression and irritation of nerves. But a simple injection into the lumbar epidural space usually goes into the area of least resistance and cannot deliver the medication to the target area. Thus, the adhesiolysis of the affected area is sometimes mandatory. We performed an adhesiolysis, irrigating with normal saline, and targeted an injection of a local anesthetic and steroid mixture to the epidural space, using a flexible catheter-secured epiduroscopic unit in 15 patients with low back pain, and assessed the pain score changes. METHODS: With the patient in the prone position, the epidural space was entered with a 17-gauge Tuohy needle. A guide-wire was inserted through the needle and advanced under fluoroscopic guidance to the level of the suspected pathology. A catheter was then advanced over the guide-wire. After the removal of the guide-wire, an adapter was then attached to the proximal end of the catheter, and its side arm was connected to a syringe containing normal saline flush. The 0.9 mm diameter fiberoptic scope was introduced into the catheter via the adaptor, and a video camera was then attached. Gentle irrigation of normal saline less than 50 ml distended the epidural space. The catheter and fiberoptic scope were advanced to the adhesion area and adhesiolysis was done by moving the tip of the steering catheter. Assuming that original NRS (Numeric Rating Scale) before the procedure was 10, we asked the NRS at 1, 4, 8, 12, 16 weeks after the epiduroscope. RESULTS: NRS at 1, 4, 8, 12, 16 weeks after the epiduroscope showed significant decrease of both low back pain and radiating pain, compared with the original pain (P<0.05). CONCLUSIONS: The flexible catheter-secured epiduroscopic unit proved to be painless, safe, and more simple, than an operation, it is, thus, a practical method for pain relief using adhesiolysis and irrigation of epidural space under the direct visualization of the epidural space in patients with low back and lower extremity pain.

PURPOSE: To evaluate the efficiency of lateral plate fixation using minimally invasive plate osteosynthesis (MIPO) technique as a treatment of distal tibial metaphyseal fracture. MATERIALS AND METHODS: Among the patient who were treated from March, 2002 to September, 2004, the cases of twenty patients with distal tibial metaphyseal fracture treated by lateral plate fixation using MIPO technique who were able to be followed up for at least one-year period were reviewed in this study. According to AO/OTA classification, five were type A1, twelve cases were type A2 and other three cases were type A3, and among them two cases were open fracture type I according to the Gustillo-Anderson classification. Radiologic studies and clinical assessment described by Daniel et al and complication following the treatment were evaluated. RESULTS: At a mean of 16.4 weeks (range 11 to 23), all fractures united without secondary procedures. According to clinical assessment, all cases had good and excellent result, and there were no complications. CONCLUSION: The lateral plate fixation using MIPO technique of distal tibial metaphyseal fracture is an efficient method of treatment with high functional recovery rate which minimize soft tissue damage, decreases the risk of infection and incidence of nonunion at the same time as the classic MIPO technique does, and it is a useful alternative method when there is a anteromedial soft tissue damage.

PURPOSE: The purpose of this study was to investigate usefulness of locking compression plate (LCP) as an open reduction technique by evaluating clinical results obtained from the patients with lateral malleolar fracture treated by internal fixation using LCP after open reduction. MATERIALS AND METHODS: Among the patients with lateral malleolar fracture, the 28 patients who were treated by internal fixation using Locking compression plate after an open reduction and were able to be followed up for more than 6 months were included in this study. Final postoperative evaluation was done based on the Meyer's clinical and radiologic evaluation system. RESULTS: All cases achieved anatomical reduction and fixation of the reduction postoperatively. 28 minutes were taken meaningly from the incision to the fixation of LCP plate after the anatomical reduction. Everage bony union time was 8.2 weaks, and the result was excellent in 23 cases (82%), good in 5 cases (17%) and poor result was abscent according to the criteria of Meyer et al. One case of post traumatic arthritis and one case of superficial infection on the operation site were found, but non-union, delayed union and malunion were not occurred. CONCLUSION: The internal fixation after open reduction using LCP is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including easy application and a greater stability due to its capability of maintaining exact anatomical reduction even though the screw does not penetrate the medial cortex of fibular to add the stability and rigidity of the fixation.

PURPOSE: To evaluate the clinical result of two stage reimplantation of infected total knee arthroplasties, using an antibiotics impregnated articulating cement spacer. MATERIALS AND METHODS: Out of total 7 cases with infected total knee arthroplasties, 4 cases treated with two stage reimplantation, using an antibiotics impregnated articulating cement spacer were included in this study. After the treatment of infected total knee arthroplasties, the treatment of infection was evaluated by physical examination, radiologic studies, and hematologic studies. The results were evaluated using the Hospital for Special Surgery Knee Score (HSS). RESULTS: As results, 4 infected knee cases treated with two stage reimplantation did not have reinfection at the time of the follow up, and physical, laboratory, and radiologic studies were all within normal range. The range of motion of the reimplanted knees were from -5degrees in extension to 130 degrees in flexion, with an average of 117 degrees. The average score of the Hospital for Special Surgery Knee Score was 87. CONCLUSION: In conclusion, two stage arthroplasties, using antibiotics impregnated articulating cement spacer was an effective therapy not only for the treatment of the infection after the total knee arthroplasty but also effectiveness for recovery of the knee function.

Purpose:
To report a case of congenital trichomegaly.Case summary: A 7-year-old girl visited our clinic with decreased visual acuity. The uncorrected visual acuity was 0.2 in the right eye and 0.3 in the left eye. The length and number of upper and lower eyelashes were increased. The eyelash length was 10 mm on the peripheral edge and 15 mm in the central area. Trichiasis and ptosis were also noted. There were no abnormal findings in the additional fundus examination or visual evoked potential test. There was no family history of trichomegaly, no abnormalities in blood test results, and no medication history. The patient is currently undergoing follow-up treatment for low visual acuity and mild ptosis under the diagnosis of trichomegaly.
Conclusions
Trichomegaly is associated with family history, various congenital diseases, and acquired diseases. However, it may occur congenitally, without specific causes.

AIMTo evaluate the effects of 60 Hz extremely low frequency (ELF) elelctromagnetic field (EMF) exposure on germ cell apoptosis in the testis of mice.
METHODSAdult male BALB/c mice (7 weeks of age) were exposed to a 60 Hz EMF of 0.1 mT or 0.5 mT for 24 h/day. A sham-exposed group served as the control. After 8 weeks of exposure, the mice were sacrificed. Germ cell apoptosis in the testis was assessed by histopathological examination, the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) and flow cytometric examination of isolated spermatogenic cells stained with 7 aminoactinomycin D (7-AAD).
RESULTSEMF exposure did not significantly affect the body and testis weights, but significantly increased the incidence of germ cell death. The distinguishing morphological feature of EMF exposure was a decrement in the number of well organized seminiferous tubules. Quantitative analysis of TUNEL-positive germ cells showed a significantly higher apoptotic rate in the 0.5 mT exposed mice than that in the sham controls (P<0.05), while the difference between the two exposed groups was insignificant. The TUNEL-positive cells were mainly spermatogonia. In flow cytometry analysis, the percentage of live cells [forward scatter count (FSC)(high)7-AAD(-)] was lower in the exposed groups than that in the controls (Figure 5A), but the decrease in viability was not statistically significant.
CONCLUSIONContinuous exposure to ELF EMF may induce testicular germ cell apoptosis in mice.

We report a case of pure red cell aplasia due to parvovirus B19 infection in a renal transplant recipient. The patient was a 32-year-old male with end stage renal disease due to chronic glomerulonephritis, who had been undergoing regular hemodialysis. He received a living nonrelated renal transplant and immumosuppressive therapy including prednisolone, tacrolimus, and mycophenolate mofetil. One week after kidney transplantation, severe anemia was persisted despite recombinant human erythropoietin administration and packed red blood cell transfusion. His bone marrow aspiration smear demonstrated erythroid hypoplasia and giant pronormoblasts with prominent intranuclear inclusions. Both serum and bone marrow were positive for parvovirus B19 DNA polymerase chain reaction and anti-parvovirus B19 IgM. He was treated with intravenous immunoglobulin and conversion of tacrolimus to cyclosporine. His hemoglobin level was completely recovered three months later.
