Nutcracker syndrome is a rare disease caused by the compression of the renal vein between the aorta and superior mesenteric artery. It is known to cause of venous hypertension, peripelvic and periureteral varicosities. Clinical manifestations include varicocele, hematuria, and flank or abdominal pain. Surgical correction is needed in nutcracker syndrome cases with severe or recurrent hematuria and abdominal or flank pain. Reanastomosis of the renal vein at 5cm below the original insertion site at the inferior vena cava is the one of the most common corrective methods and the transabdominal approach is usually employed. This disease usually appears in healthy young people and in order to decrease postoperative complications such as intestinal obstruction and bowel adhesion by avoiding unnecessary intraperitoneal manipulation, the authors used the extraperitoneal approach through a flank incision. We report because, in selected cases, we consider that this extraperitoneal approach is one of the alternative methods for the usual transperitoneal approach.

One of the serious and challenging problems confronting orthopaedic surgeons is an open un-united fracture of tibia. Especially, there are some difficulties in getting bone union on the condition of combining soft tissue defect with infection. In the management of infected un-united fracture of tibia with significant soft tissue loss we attempted a two-stage reconstruction : the first stage consisted of radical sequestrectomy, soft tissue reconstruction, and external fixation, and the 2nd stage consisted of various types of bone grafting and bone fixation. Fifteen patients with open infected un-united fractures of tibia treated with staged reconstruction from September 1982 to August 1987 at Department of Orthopaedic Surgery, Dae-Jeon's St. Mary's Hospital, Catholic University Medical College, were analyzed in clinical aspects and the results of treatment obtained were as follows : 1. Satisfactory bone union was obtained in an average of 6 months after bone graft with a range of 4 months to 12 months. 2. The duration from the injury to bone union was 13 months on an average with a range of 8 months to 19 months. 3. The soft tissue rer.onstruction at the first stage were performed with local flap in 11 cases and muscular flap in 2 cases and musculocuteneous flap in 2 cases. 4. The time interval between 1st stage and 2nd stage was from 1.5 months to 3 months. 5. At the 2nd stage, bone graft were performed with autogenous cancellous bone graft in 11 cases, vascularized osteocutaneous fibular graft in 2 cases and ipsilateral vascularized fibular transference in 2 cases. In summary, a two-stage reconstruction for open infected un-united fracture of tibia is a advisable procedure that leads to bone union with satisfactory return of function.

PURPOSE : 99mTc DMSA renal scan have been widely used not only for the evaluation of renal scars but also for the diagnosis of acute pyelonephritis. Recent studies have shown SPECT images have higher accuracy than the planar images with some controversy. We evaluated the availability of the SPECT images adding to planar images for the diagnosis of acute pyelonephritis(APN) and renal scar in children with urinary tract infection (UTI). METHODS : 130 children with UTI (260 kidney units) and 22 follow-up children (44 kidney units) were included between January 1, 1997 and July 31, 1999 at Ewha University Mokdong Hospital. Planar Anterior and posterior images and SPECT axial and coronal images of 99mTc DMSA renal scan were obtained with Starcam 4000-i U.S.A. GE at 3 hours after 99mTc DMSA I.V. injection. The data were analyzed by Chi square test after Yates's correction. RESULTS : The detection rate of the acute pyelonephritis by SPECT images was 12.3% higher than that of planar images (47.7% vs 35.4%) by the patient and 6.9% higher also (31.9% vs 25.4%) by the kidney unit. 18 kidney units with negative planar images had focal defect in 10 kidney units (3.8%) and multifocal defect in 8 kidney units (3.1%) on SPECT images, but 1 kidney unit with positive planar image had negative SPECT image. SPECT images were superior to the planar images in 17.3%, identical in 82.3% and inferior in 0.4% to planar image. The detection rate of the renal scars by SPECT images was 13.7% higher than planar images by the patient (68.2% vs 54.5%) and 6.8% higher also (43.2% vs 36.4%) by the kidney unit. SPECT images were superior to the planar images in 17.3% and identical in 82.3% to planar image. CONCLUSION : SPECT images had shown higher detection rate and better image than planar images for the diagnosis of the acute pyelonephritis and the evaluation of the renal scars.

BACKGROUND: AND PURPOSE: Gamma-glutamyl transferase (GGT) is reported to be associated with stroke independently of the conventional risk factors. However, the underlying mechanism remains to be identified. This study focused on atrial fibrillation (AF), which also reportedly has a close association with GGT. METHODS: Acute ischemic stroke patients who were admitted to the Seoul National University Hospital within 7 days of stroke onset were analyzed. Multinomial logistic regression was performed to assess the relationship between GGT and cardioembolic stroke. Mediation analysis based on binary logistic regression was used to determine whether AF mediates the relationship between GGT and cardioembolic stroke. RESULTS: AF was found in 132 (15.0%) of 880 eligible patients with acute ischemic stroke, and 270 (30.7%) patients were categorized as cardioembolic stroke. High GGT levels in acute ischemic stroke patients was associated with cardioembolic stroke [odds ratio (OR)=3.42, 95% CI=1.59–7.37], but not with large-artery atherosclerosis stroke (OR=1.10, 95% CI=0.54–2.23). Approximately half (53.9%) of the total effect of GGT levels on cardioembolic stroke was mediated by AF. CONCLUSIONS The GGT level was significantly associated with cardioembolic stroke via AF. The results obtained in the present study may explain why GGT is associated with stroke.
