Because of congenital deficiency of the superior sacral facet of S1 or the arch of L5 in dysplastic spondylolisthesis, progression of slippage may occur even in the presence of a posterior solid arthrodesis, especially in the patients with high degree of slippage and lumbosacral kyphsis. Therefore, the anterior interbody fusion may be necessary additionally. But the operation is very difficult because of a little supporting structure anteriorly for bone grafting. We have a case of dysplastic spondylolisthesis which showed progressive slippage even though solid posterolateral fusion. On which case we performed additional anterior interbody fsuion by the technique of anterior open wedge osteotomy on the superior dome of sacrum to support the L5 on S1. And this is the case report of the result.

Myxoma is the commonest intracardiac tumor and it is well known to present in bizarre ways. Calcification of the tumor is uncommon, though probably more frequent in right than in left heart tumors. Diagnosis can be followed by surgery with satisfactory results. A 36 years old man with partially calcified right ventricular myxoma and a 51 years old man with calcified left atrial myxoma, which were revealed different echogenic densities on 2-dimensional echocardiogram and gross calcification on fluoroscopy, were treated with surgical removal. We report above two cases of calcified myxoma with literature review.

Merkel cell carcinoma is a skin disease that rarely involves the spine. The common presentation of spinal involvement is quite confusing and may be easily misdiagnosed. However, once it spreads, the disease progresses rapidly, with an extremely poor outcome. We report on the case of a 30-year-old male with cervical spinal metastasis of Merkel cell carcinoma causing quadriparesis.

BACKGROUND: This study investigates the potential volume and outcome association of coronary heart disease (CHD) patients who have undergone percutaneous coronary intervention (PCI) using a large and representative sample. METHODS: We used a National Health Insurance Service-Cohort Sample Database from 2002 to 2013 released by the Korean National Health Insurance Service. A total of 8,908 subjects were analyzed. The primary analysis was based on Cox proportional hazards models to examine our hypothesis. RESULTS: After adjusting for confounders, the hazard ratio of thirty-day and 1-year mortality in hospitals with a low volume of CHD patients with PCI was 2.8 and 2.2 times higher (p=0.00) compared to hospitals with a high volume of CHD patients with PCI, respectively. Thirty-day and 1-year mortality of CHD patients with PCI in low-volume hospitals admitted through the emergency room were 3.101 (p=0.00) and 2.8 times higher (p=0.01) than those in high-volume hospitals, respectively. Only 30-day mortality in low-volume hospitals of angina pectoris and myocardial infarction patients with PCI was 5.3 and 2.4 times those in high-volume hospitals with PCI, respectively. CONCLUSION: Mortality was significantly lower when PCI was performed in a high-volume hospital than in a low-volume hospital. Among patients admitted through the emergency room and diagnosed with angina pectoris, total PCI volume (low vs. high) was associated with significantly greater cardiac mortality risk of CHD patients. Thus, There is a need for better strategic approaches from both clinical and health policy standpoints for treatment of CHD patients.

OBJECTIVE: The frontal sinus is frequently a troublesome anatomical obstacle to gain access to the medial anterior cranial base. Surgical approaches to and through the frontal sinus using osteoplastic frontal sinusotomy provide significant advantages to the treatment of lesions of the medial anterior cranial base in addition to the frontal sinus itself. However, appropriate management is necessary to avoid postoperative complications such as cerebrospinal fluid leakage, infection, mucocele formation, and deformity of the forehead. METHODS: The advantages and shortcomings of the approach along with the surgical technique are reported based on our clinical experience with pertinent literature review. The approach using the osteoplastic frontal sinusotomy was applied to two cases of osteoma in the frontal sinus, seven cases of craniofacial tumors, a case of chordoma in the sphenoid and clivus, and two cases of intradural lesions in the anterior cranial fossa. The frontal sinus was managed in such a way as to prevent the postoperative complications. RESULTS: All patients underwent gross total resection of the tumors. With a mean follow-up of 26 months, there were no postoperative complications related to frontal sinus violation. CONCLUSION: The neurosurgical approaches via the frontal sinus using osteoplastic frontal sinusotomy are versatile for various lesions of the anterior cranial base in patients with large frontal sinuses. In situations that the frontal sinus have to be violated to approach medial anterior cranial base, the osteoplastic frontal sinusotomy provides such advantages as optimal frontal sinus control to prevent postoperative complications; increases viewing angle with superior trajectory from nasofrontal suture; lower incidence of pnemocephalus due to minimal dural exposure; and excellent cosmesis without frontal burr holes.
