We report a case of 17-year-old female with juvenile onset systemic lupus erythematosus Who developed symptomatic unilateral sacroiliitis. She had neither HLA-DR3 nir B27 antigens. Though sacroiliitis have been reported in mail SLE patient. it has been rarely reported in female patients. The rare coexistence of SLE and sacroiliitis. described in this case. may not be determined soley by genetic factors; sacroiliitis may be just an infrequent manifestation of SLE.

Advanced age is a well-known risk factor for spinal surgery-related complications. Decisions on spine surgery in the elderly are difficult due to higher morbidity and mortality than in younger age groups. In addition, spine surgery is a kind of ‘functional surgery’ which does not directly affect the survival of patients. In recent years, individualized risk stratification has gained ground over simple chronological age-based assessment. In the elderly, frailty is one of the strongest factors which affect surgical outcomes for both cervical and thoracolumbar spine surgery, regardless of the surgical technique used. Spine surgery in the elderly have worse surgical outcomes in terms of duration of hospital stay, degree of functional recovery, and complication, readmission, and mortality rates. However, the benefit of spine surgery even in the very-elderly is substantial. In conclusion, surgical decisions should be made based on both personalized risk assessment and benefits of surgery. Recent advanced surgical techniques such as minimally invasive surgical techniques and robotics assistance are likely to be helpful in minimizing surgical complications. Therefore, advanced age in itself should not be considered as a contraindication for spine surgery.

PURPOSE: To compare the pullout strength and insertion torque of proximally tapered screw (PT) with fully tapered screw (FT) and to investigate the correlation between the pullout strength and bone mineral density, morphology of pedicle, and insertion torque of the screw in osteoporotic lumbar spine. MATERIALS AND METHODS: Fifteen osteoporotic lumbar vertebrae from four white human cadavers were used. Bone mineral density, pullout strength and insertion torque were measured by dual energy x-ray absorptiometry, MTS and torque screw driver individually. RESULTS: The FT screw provided greater pullout force and insertion torque than the PT screw in 12 of 15 vertebrae tested (p<0.01). Pullout strength was correlated with insertion torque in PT (r=0.666, P=0.0006) and FT (r=0.464, P=0.19) screws. CONCLUSIONS: Results of this study indicate that the FT screws provide higher pullout strength and insertion torque than PT screws in osteoporotic lumbar spine and suggest that the development of tapered minor diameter may lead to an improved pedicle screw with high pullout strength and insertion torque. Nevertheless, further study is needed to investigate the effect of tapering the minor diameter on the mechanical bending strength of the screw.

BACKGROUND: Totally implantable access port (TIAP) provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. METHODS: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92) and subclavian approach (Group 2, n = 79) between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. RESULTS: Median follow-up for TIAP was 278 days (range, 1-1868). Twenty four complications were occurred (14.0%), including pneumothorax (n = 1, 0.6%), migration/malposition (n = 4, 2.3%), pinch-off syndrome (n = 4, 2.3%), malfunction (n = 2, 1.1%), infection (n = 8, 4.7%), and venous thrombosis (n = 5, 2.9%). The overall incidence was 8.7% and 20.3% in each group (p = 0.030). Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033). The mechanical complication free probability is significantly higher in group 1 (p = 0.040). CONCLUSIONS: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

BACKGROUND: Catheter ablation using radiofrequency energy has been established as the most important mode of treatment in patients with accessory pathway. However the ablation of midseptal accessory pathways had been recognized as being more difficult to ablate than other located pathway because of the low incidence and the difficult localization of ablation site. This paper describes the electrophysiologic characteristics of successfully ablated midseptal accessory pathway using radiofrequency energy. METHOD: Routine electrophysiologic studies were performed in 13 patients with midseptal accessorypathway. Guided by the recording of VA interval, the ablation catheter was positioned in all patients in an area bounded anteriorly by the tip electrode of the His bundle catheter and posteriorly by the coronary sinus ostium. Local electrograms during orthodromic atrioventricular reentrant tachycardia or right ventricular apical pacing were compared for 13 patients with midseptal accessory pathway and consequent 13 patients with posteroseptal accessory pathway. RESULT: 13 patients with midseptal accessory pathway; eight with constant Wolff-Parfinson-White syndrome, one with intermittent Wolff-Parkinson-White syndrome and four with concealed bypass track underwent attempts at ablation of their pathway using radiofrequency energy. 11 accessory pathways were successfully ablated without complication during the firstsession. A second attempt at ablation was made in two patients with success(one; recurred case, the other one; failed case at the first session). In the surface 12-Lead ECG, all eight patientswith constant Wolff-Pakinsin-White syndrome had not shownen Qrs complex at lead 3. Two patient with midseptal accessory pathway had transient left bundle branch block during orthodromic tachycardia. The VA interval during left bundle branch block was not change compared to that during narrow complex tachycardia in both. In all patients with midseptal accessory pathway, the VA interval in his bundle electrogram were almost similar to that in the coronary sinus ostial electrogram, which was not observed in the patients with posteroseptal accessory pathway. CONCLUSION: We suggest that VA interval during orthodromic tachycardia and right ventricular apcial pacing is the most reliable market for identifying midseptal accessory pathway, especially distinguishing from posteroseptal accessory pathway.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

PURPOSE: Segmental parenchymal excretion delay on Tc-99m DISIDA scan is caused by intrahepatic bile duct obstruction. However, the diagmostic value for intrahepatic bile duct obstruction is unknown. We conducted this study to assess the positive predictive value of segmental excretiom delay for the diagnosis of intrahepatic bile duct obstruction, and additional benefit over other noninvasive radiologic studies. MATERIALS AND METHODS: The study population consisted of 43 patients (48 scans) Who showed segmental parenchymal excretion delay on Tc-99m DISIDA scan. The results of abdominal CT or ultrasonography, which was done within 1 month of Tc-99m DISIDA scan, were compared with scintigraphic findings. RESULTS: The etiology of segmental parenchymal excretion delay was determined by ERC or PTC in 31 scans, and follow-up studies in 13 scans. No causes were identified in 4 scans. The positive predictive value of segmental parenchymal excretion delay for intrahepatic bile duct obstruction was 92% (44/48). On the other hand, 13% (5/38) of CT and 28% (5/18) of ultrasonography were normal. In 18% (7/38) of CT and 17% (3/18) of ultrasonography, only intraheipatic bile duct dilatation was noted without any diagnostic findings of intrahepatic bile duct obstruction. CONCLUSION: Segmental parenchymal excretion delay on Tc-99rn DISIDA scan had a high positive predictive value for the diagnosis of intrahepatic bile duct obstruction. Tc-99m DISIDA scan may be useful for the diagnosis of intrahepatic bile duct obstruction, especially in patients with nondiagnostic CT or ultrasonography. The diagnostic usefulness need to be confirmed by further prospective studies. KW: Tc-99m DISIDA, Segmental parenchymal excretion delay, Intrahepatic bile duct obstruction.

Limb paralysis can develop for various reasons. We found a 13-year-old patient who became paralyzed in her lower extremities after laparoscopic appendectomy. Some tests, including electrodiagnostic studies and magnetic resonance imaging, were performed to evaluate the cause of lower limb paralysis. None of the tests yielded definite abnormal findings. We subsequently decided to explore the possibility of psychological problems. The patient was treated with simultaneous rehabilitation and psychological counseling. Paralysis of the patient's lower extremity improved gradually and the patient returned to normal life. Our findings indicate that psychological problems can be related to limb paralysis without organ damage in patients who have undergone laparoscopic surgical procedures.
