Methods: Cases of 50 patients with ASD who underwent long spinal fusion (>9 levels) with S2AI screws were retrospectively reviewed. Loosening of S2AI screws and S1 pedicle screws and bone fusion at the level of L5–S1 at 2 years after surgery were investigated using computed tomography. In addition, risk factors for loosening of S2AI screws were determined in patients with ASD. Results: At 2 years after surgery, 33 cases (66%) of S2AI screw loosening and six cases (12%) of S1 pedicle screw loosening were observed. In 40 of 47 cases (85%), bone fusion at L5–S1 was found. Pseudarthrosis at L5–S1 was not significantly associated with S2AI screw loosening (19.3% vs. 6.3%, p=0.23), but significantly higher in patients with S1 screw loosening (83.3% vs. 4.9%, p<0.001). On multivariate logistic regression analyses, high upper instrumented vertebra (UIV) level (T5 or above) (odds ratio [OR], 4.4; 95% confidence interval [CI], 1.0–18.6; p=0.045) and obesity (OR, 11.4; 95% CI, 1.2–107.2; p=0.033) were independent risk factors for S2AI screw loosening. Conclusions High UIV level (T5 or above) and obesity were independent risk factors for S2AI screw loosening in patients with lumbosacral fixation in surgery for ASD. The incidence of lumbosacral fusion is associated with S1 screw loosening, but not S2AI screw loosening.

BACKGROUND/AIMS: L-carnitine not only alleviates hyperammonemia and reduces muscle cramps in patients with liver cirrhosis, but also improves anemia in patients with chronic hepatitis and renal dysfunction. This study prospectively evaluated the preventative efficacy of L-carnitine supplementation against hemolytic anemia during antiviral treatment using ribavirin in patients with hepatitis C virus (HCV)-related chronic liver disease. METHODS: A total of 41 patients with chronic hepatitis were consecutively enrolled in this study. Group A (n=22) received sofosbuvir plus ribavirin for 3 months, whereas group B (n=19) was treated with sofosbuvir, ribavirin, and L-carnitine. Hemoglobin concentration changes, the effects of antiviral treatment, and the health status of patients were analyzed using short form-8 questionnaires. RESULTS: A significantly smaller decrease in hemoglobin concentration was observed in group B compared to group A at every time point. Moreover, the prescribed dose intensity of ribavirin in group B was higher than that of group A, resulting in a higher ratio of sustained virological response (SVR) 24 in group B compared with group A. The physical function of patients in group B was also significantly improved compared to group A at the end of antiviral treatment. CONCLUSIONS: L-carnitine supplementation alleviates ribavirin-induced hemolytic anemia in patients with HCV and helps relieve the physical burden of treatment with ribavirin-containing regimens. These advantages significantly increase the likelihood of achieving SVR.

We investigated original texts for yokukansan, a familiar Kampo formula, focusing on the classical literature Xue-shi yi-an (薛氏医案) . Yokukansan was described in the Bao-ying jin-jing-lu (保嬰金鏡録) written by Xue ji (薛己) in 1550, the Xiao-er yao-zheng zhi-jue (小児薬証直訣) revised by Xue ji (薛己) in 1551,the Bao-ying cuo-yao (保嬰撮要) by Xue kai (薛鎧) in 1556, and the Xiao-er dou-zhen fang-lun (小児痘疹方論) in 1550. The phrase “one's own work” was used in “Bao-ying jin-jing-lu (保嬰金鏡録)” and in the Xiao-er dou-zhen fang-lun (小児痘疹方論) by Chen wen-zhong (陳文仲). However, there was no mention of “one's own work” in the same title, the Xiao-er dou-zhen fang-lun (小児痘疹方論), as summarized by Xiong zong-li (熊宗立).
Yokukansan was found only in the Xiao-er yao-zheng zhi-jue (小児薬証直訣) revised by Xue ji (薛己) in 1551, but not in the other copies of the same text. Therefore, it seems likely that yokukansan was created by Xue ji (薛己) himself.
Yokukansan was previously thought to have originated with the Bao-ying cuo-yao (保嬰撮要). However, based on use of the phrase “one's own work” in the classical literature, it appears that the original text for yokukansan should be the Bao-ying jin-jing-lu (保嬰金鏡録). Therefore, yokukansan seems to have been made by Xue ji (薛己), and not Xue kai (薛鎧), who was his father.

We report a case of ulcerative colitis (UC) after mitral valve replacement (MVR) surgery due to infective endocarditis (IE). A 59-year-old woman underwent MVR for mitral regurgitation due to IE. Six days after the surgery, melena was observed suddenly, and she received a blood transfusion. Ulcer and erosion were observed in the rectum 5 to 10 cm from the anal ring by endoscopy. We changed her antibiotic treatment and stopped warfarin potassium. Heparin sodium was started 2 days after melena. We diagnosed ulcerative colitis from the finding of the rectal lesion and biopsy. We gave mesalazine and betamethasone as treatment for UC. The patient's condition improved and her general condition stabilized. She was discharged 36 days after surgery.

A 51-year-old man with osteogenesis imperfecta and who had aortic regurgitation was admitted to our hospital for aortic valve replacement. His height was 146cm and his weight was 49kg. The patient had suffered from bone fractures several times since childhood. Bone deformity, blue sclera and his status were clinically indicative of osteogenesis imperfecta. Aortic valve replacement with a 25mm SJM^® prosthetic valve was successfully performed for aortic valve insufficiency and slight annulo-aortic ectasia. Soft tissues and the sternum were fragile. Pathological examination (Elastica-Masson stain) of the aortic valve and left ventricular wall revealed a loss of fibrous tissues and remarkable thickening due to elastic fibers. The patient was discharged 31 days after surgery. Osteogenesis imperfecta is one of the collagen diseases caused by gene abnormality, in which fragile bones are easily fractured. Cardiovascular disease is rarely associated with it and the surgery-related mortality rate is reported to be approximately 30%, due to bleeding.

A 68-year-old woman complained of hemoptic shock and recovered with conservative treatment. Ruptured descending aorta into the left lung was diagnosed. Graft replacement of the descending aorta was successfully performed. We speculated that spontaneous rupture of the descending aorta into the left lung might have occurred due to high blood pressure affecting the weak aortic wall with sclerotic change, causing hemoptysis. The ruptured descending aorta was successfully replaced without dissection between the ruptured aorta and the left lung. The postoperative course was uneventful with neither pulmonary nor infectious complications.

A 45-year-old woman who was a Jehovah's Witness was admitted to our hospital with a complaint of palpitation and sort on-effort. A ruptured aneurysm of the sinus of Valsalva (RASV) associated with stenosis of the right ventricular outflow was diagnosed. Operative findings revealed a RASV with a double chambered right ventricle (DCRV) and a ventricular septal defect (VSD). RASV, DCRV and VSD were successfully repaired with extracorporeal circulation without use of homologous blood. We reported this case because congenital combination of RASV, DCRV and VSD is very rare.

A 69-year-old man complained of abdominal pain with inflammatory reaction. Abdominal aortic aneurysm (AAA) with a left main trunk lesion was diagnosed and he successfully underwent Y-graft replacement of the abdominal aorta and coronary artery bypass grafting. Finally AAA was classified as “inflammatory” by histopathological findings. We present this case of “inflammatory AAA” associated with coronary artery disease, and discuss it with a review of literatures.

A 75-year-old male visited Fuchu general hospital on foot because of possible acute mushroom poisoning. He had no symptom on admission. He twice ate some toxic mushrooms for lunch and for dinner on the previous day with his wife, who was found dead in her bed on the morning of his admission. A legally ordered autopsy was held on his wife, and a-amanitin was detected in her liver, brain and blood samples. Detection of a-amanitin in blood samples has never been reported in the literature. His liver and kidney failure rapidly progressed. He died on the 10th hospital day despite intensive treatment including hemodialysis and plasma exchange. On histological examination, his necropsy liver specimen revealed massive liver necrosis and new growth of pseudocholangioles, which apparently bore testimony to acute toxic mushroom poisoning.
