Spinal fusion has performed for instability and anatomical reconstruction since 1985 by Barthe. Bone grafts and synthetic materials has been used for spinal fusion, but they have several limitations and complications. Recently a new synthetic polymer B.O.P.(Biocompatible Osteoconductive Polymer) was developed and it overcome the limitations of other materials. The B.O.P. showed no foreign body reaction and gave scaffolding for the osteoconduction and osteointegration. Authors operated 35 cases of spinal fusion with B.O.P. and the results and literature reviews were discussed.

Anterior interbody fusion has used for instability and anatomical reconstruction in various cervical diseases since 1958 by cloward. Bone grafts such as autograft, allograft, xenograft and synthetic materials were utilized in fusion as a graft material. But conventional fusion materials have problems including postoperative morbidity, transmission of diseases, foreign body reaction, collapse, prolongation of operation time. A new synthetic material, Biocompatible Osteoconductive Polymer(B.O.P) is developed and it was useful for cervical anterior interbody fusion as a substitute for other fusion materials.

Mayer-Rokitansky-Kster-Hauser Syndrome is characterized by the absence of the vagina and uterus, the presence of apparently normal tubes and ovaries, feminine appeara-nce, normal female secondary sexual characteristics, a normal 46,XX karyotype, and a fem-inine psychosexual orientation. Various methods of surgical treatment have been introduced, but the ideal method is still not found. The two cases reviewed in this paper were all treated with McIndoe operation using full thickness skin graft. Both women were satisfied with vaginal depth and excellent result was achieved. We report two vaginoplasties in patients of Mayer-Rokitansky-Kster-Hauser Syndr- ome including a brief review of literature.

Authors measured the Y-shaped angle made by both yellow ligaments and both laminae named Y-angle at the spinal CT scan in normal and lumbar stenosis group. The normal range of Y-angle is between 60 degrees and 95 degrees. Lumbar stenosis is classified into narrow Y-angle stenosis(<60 degrees) and wide Y-angle stenosis(>95 degrees) by Y-angle. Narrow Y-angle stenosis is most common in degenerative spondylotic stenosis. Wide Y-angle is most common in congenital stenosis. The Y-angle is a simple and useful diagnostic indicator in the diagnosis of lumbar spinal stenosis on CT scan and MRI scan.

BACKGROUND: The correlation between the high resolution computed tomography(HRCT) emphysema score and the physiologic parameters including resting and exercise pulmonary function test was investingated in 14 patients(60.6±10.3 years) with pulmonary emphysema. METHODS: The patients underwent a HRCT, a resting pulmonary function test, and incremental exercise testing(cycle ergometer, 10 W/min). Computed tomography scans were obtained on a GE highlight at 10 mm intervals using 10 mm collimation, from the apex to the base after a full inspiration. The emphysema scores wer determined by a CT program 'Density mask' outlining the areas with attenuation values less than -900 HU, indicating the emphysema areas, and providing an overall percentage of lung involvement by emphysema. RESULTS: Among the resing PFT parameters, only the diffusing capacity(r=-0.75) and PaO2 (r=-0.66) correlated with the emphysema score(p<0.05). Among the exercise test parameers, the emphysema score correlated significantly with the maximum power(r=-0.74), maximum oxygen consumption(r=-0.68), anaerobic threshold(V-slope method : r=-0.69), maximal O2-pulse(r=-0.73), and the physiologic dead space ratio at the maximum workload(r=-0.80)(p<0.01). CONCLUSION: We could find that exercise testing parameters showed a much better correlation with the HRCT emphysema score, which is known to have a good correlation with the pathologic severity than the resting PFT parameters. Therefore it is suggested that exercise testing is superior to resting PFT for estimating in the estimation of the physiologic disturbance in emphysema patients.

A case of extradural cavernous hemangioma on lumbar spine combined with ruptured disc is reported. Cavernous hemangiomas are uncommon vascular malformation of the central nervous system. In the spine, the majority of these lesions are from secondary extensions of vertebral hemangiomas. Occurrence of a primary extradural cavernous hemangioma is relatively rare. Authors report a case of extradural cavernous hemangioma of the spine with the review of literatures.

BACKGROUND: Although stress-induced cardiomyopathy (SCMP) is reported to be more common in women, little is known about gender differences in patients with SCMP. The aim of the study was to describe clinical features of patients with SCMP according to gender. METHODS: One hundred and three patients diagnosed with definite SCMP at a single tertiary institute from January 1997 to August 2014 were enrolled. SCMP was more common in women than in men. RESULTS: Age at presentation was not significantly different between the two groups (p = 0.758). Preceding physical stress, especially acute medical illness, was more common in male patients (p = 0.014), whereas emotional stress was more common in female patients (p = 0.016). Severity of medical illness classified by the Acute Physiology and Chronic Health Evaluation (APACHE) II score at the time of SCMP diagnosis was not significantly different between men and women (p = 0.752). Clinical characteristics, including symptoms, laboratory and electrocardiographic findings, were similar. However, pump failure was more severe in men (p = 0.024). Clinical outcomes were not statistically different (p = 0.220). Preceding physical stress and lower left ventricular systolic function after 2 months were independent risk factors for all-cause mortality for both genders. Women with an APACHE II score ≥ 15 and men with reduced left ventricular ejection fraction after 2 months had a greater risk of poor prognosis. CONCLUSION: SCMP was more common in female patients. Female patients more commonly experienced preceding emotional stress, whereas physical stress was more common in male patients. Systolic dysfunction was more severe in men. Long-term clinical outcomes appeared to be similar between men and women.

The combination therapy of pegylated interferon and ribavirin is the mainstay of treatment for chronic hepatitis C patients. Anti-viral therapy is commonly associated with side effects such as headache, fever, myalgia, and arthralgia. However, anti-viral therapy can continue because these side effects are mostly mild and can be improved with supportive management. Anti-viral therapy should be stopped promptly if serious side effects, such as interstitial pneumonitis or hemolytic anemia occur, although those serious side effects are rare. There were a few case reports of interferon-related interstitial pneumonitis worldwide. In Korea, one atypical case report of interstitial pneumonitis has been reported, which followed the combination therapy of interferon-alpha and ribavirin in a patient with chronic hepatitis C. We present a case of interstitial pneumonitis and pancytopenia following the combination therapy of pegylated interferon and ribavirin in a patient with chronic hepatitis C.
