A 60-year-old male was diagnosed as having sarcoidosis four months previously because of bilateral hilar lymphadenopathy seen on a chest X-ray, uveitis, and elevation of serum angiotensin converting enzyme. In summer, the patient suffered from hypercalcemia, hypercalciuria, and renal dysfunction. Renal biopsy showed interstitial nephritis with gallium scintigraphy demonstrating high uptake in the bilateral hilum, eyes, and kidneys. Corticosteroid treatment was effective in remarkably improving the renal disorder and radiographic abnormalities.
The calcium metabolic abnormalities and the granulomatous interstitial nephritis showed a marked response to corticosteroid therapy, so that immediate administration of corticosteroid may be justified even in cases without histological evidences. Gallium scintigraphy is suggested to be useful in noninvasive examination in acute stage of sarcoidosis.

A 64-year-old man with congenital factor V deficiency and hereditary spherocytosis was attending our hospital for type II diabetes and stage 4 diabetic nephropathy. Coronary angiography performed to assess chest pain revealed severe triple-vessel disease, including total occlusion of the right coronary artery. The patient required surgical coronary revascularization. In the preoperative examination, the activated partial thromboplastin time (APTT) and prothrombin time-international normalized ratio (PT-INR) were high (89.5 s and 1.95) and factor V activity was low (6% ; normal range, 70-135%). Hemodialysis was performed on the day of the operation, and 6 units of fresh frozen plasma (FFP) were administered, which reduced immediately the preoperative PT-INR to 1.33. We performed off-pump coronary artery bypass grafting (OPCAB) and perioperatively administered 6 units of FFP with 4 units of red blood cells (RBC) transfusion. The postoperative course of the patient was uneventful, and he was discharged on postoperative day 22. Here we report the case of a patient with a very rare disease of congenital factor V deficiency and hereditary spherocytosis complicated with stage 4 diabetic nephropathy who required OPCAB.

Four patients underwent stabilization surgery using both bilateral C2 pedicle screw (PS) and intralaminar screw (LS). Neural and vascular injury resulting from incorrect screw placement was assessed using computed tomography (CT). The evaluation of bone union was assessed by lateral flexion-extension X-ray films and CT. The symptoms were improved in all patients. There were no intraoperative complications. Furthermore, there were no cases of neurological worsening or vascular injury from incorrect screw placement. Failure of instrumentation or screw loosening during the follow-up period did not occur in any of the patients. All cases had accomplished bone union at the final follow-up. Theoretically, the stabilization technique using both bilateral C2 PS and LS at the same time can provide more stability than any other single technique. Simultaneous use of both bilateral C2 PS and LS is potentially a good choice for surgical repair.

The posterior epidural migration of lumbar disc fragments is an extremely rare event with an unknown pathogenesis. To the best of our knowledge, there are no previously reported cases of a change of ordinary disc herniation into the posterior epidural migration of lumbar disc fragments as confirmed by magnetic resonance imaging (MRI). A 26-year-old male presented to our department complaining of left buttock and lateral leg pain. An ordinary herniation was shown in the first MRI. The patient's unilateral symptoms changed into bilateral symptoms while awaiting admission to the hospital. Posterior migrated lumbar disc fragments were shown in the second MRI taken at the time of admission. Microendoscopic surgery providing a detailed observation of the region was performed. Our case indicates that an ordinary lumbar disc herniation may lead to the posterior migration of lumbar disc fragments, and that microendoscopic surgery may provide a treatment.

We report a case of syphilitic aortitis (SA) associated with severe right coronary ostial stenosis, aortic regurgitation (AR), and annuloaortic ectasia (AAE). A 48-year-old man presented to a regional hospital with easy fatigability and nocturnal dyspnea. Echocardiography revealed Seller's grade 3 AR. A computed tomography scan showed AAE, dilatation of the ascending aorta, and calcification of both coronary ostia. Coronary angiography demonstrated that the left coronary artery was intact ; however, the right coronary artery was obscure. Active syphilis was detected on routine blood tests on admission. Therefore, the patient was started on a course of ampicillin/sulbactam (ABPC/SBT). Subsequently, he underwent the Bentall procedure and coronary artery bypass grafting with the right internal thoracic artery. The intraoperative findings showed degeneration of the aorta and severe right coronary ostial stenosis. The pathological findings of the aortic wall and aortic valve were consistent with SA. The postoperative course was uneventful. The patient continued receiving ABPC/SBT for 3 weeks postoperatively, and was then switched to oral amoxicillin.

Background : Several studies have shown that Fontan circulation may lead to liver congestion and possible structural liver alteration. The aim of this study is to analyze the relationships between biochemical fibrosis markers and hemodynamic parameters in the long term after the Fontan operation.
Methods : The study enrolled 51 patients who underwent total cavopulmonary connection between March 1994 and July 2010. We analyzed the relationships between the 5 liver fibrosis markers (hyaluronic acid, retinol-binding protein, procollagen type III peptide, type IV collagen 7S, type IV collagen) and the 6 hemodynamic parameters (pulmonary artery pressure, pulmonary artery index, pulmonary vascular resistance, ejection fraction, atrioventricular valve regurgitation, cardiac index).
Results : Hyaluronic acid and type IV collagen 7S positively correlated with pulmonary artery pressure. Hyaluronic acid negatively correlated with ejection fraction, and type IV collagen 7S positively correlated with atrioventricular valve regurgitation in patients followed up for more than 8 years after Fontan completion. Pulmonary artery pressure was significantly higher in patients in whom type IV collagen 7S was elevated. Hyaluronic acid correlated with pulmonary vascular resistance (p=0.0035) and ejection fraction (p=0.014), as well as type IV collagen 7S with pulmonary artery pressure (p=0.0001) by multiple regression analysis.
Conclusion : Hyaluronic acid and type IV collagen 7S reflected the degree of hepatic congestion, and cardiac function, in the long term after the Fontan operation.

The breakage of an epidural catheter is an extremely rare complication. We describe a unique case where a retained epidural catheter fragment after epidural anesthesia was treated by surgery. The epidural catheter broke during its removal, requiring surgery to remove the retained catheter. Intraoperatively, the removal of the catheter was attempted by simple traction, but was impossible because of the adhesion. The adhesion of the dura mater surface was carefully exfoliated and the successful removal of the catheter was accomplished. Conventionally, it was said that this follow-up was enough for the retained catheter. However, if a catheter is retained within the spinal canal, surgical removal should thus be considered before the adhesion advances.

Methods: Seven patients with spinal cord compression without obvious segmental instability at the C1/2 level treated by C1 laminoplasty were included. The indication of C1 laminoplasty was same as that of C1 laminectomy. C1 laminoplasty was performed in the same way as subaxial double-door laminoplasty. The imaging findings were evaluated using X-ray, computed tomography, and magnetic resonance imaging. The clinical results were evaluated using the Japanese Orthopaedic Association (JOA) Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and JOA score. Peri- and postoperative complications were also investigated. Results: No patient showed increased C1/2 segmental instability after the surgery. The mean pre- and postoperative JOA scores were 8.6 and 11.7, respectively. The mean recovery rate was 40.2%. The effective rate in the JOACMEQ was 50% for the cervical spine function, 33% for the upper extremity function, 50% for the lower extremity function, 17% for the bladder function, and 17% for the quality of life. No major complication that seemed to be unique to C1 laminoplasty was observed over a period of about 4 years follow-up. Conclusions C1 laminoplasty for patients without obvious segmental instability might be a viable alternative procedure to C1 laminectomy.
