During the period of two years from 2001 to 2003, we treated nine cases of takotsubo-type myocardiopathy. In this paper, the clinical characteristics and patients' conditions are described, and the mechanisms leading to dyskinesia of the muscular walls of the heart are discussed. All the cases were female. The mean age was 73 years. Physiological as well as psychological stress was implicated as a major cause of the disease, with onset occurring when some members of their family were suddenly taken ill or when they started quarreling with others. Echocardiograms revealed sigmoid septa in almost half of the nine patients. The prognosis was good. Only one patient had cardiac insufficiency as a sequela, but her condition improved. No one died.Eight patients got over dyskinesia of the left ventricular walls in two weeks. From our experience and studies of literature, we ruled out the possibility of the involvement of circulatory disorder and myocarditis in the onset of the disease. Women of advanced age are apt to have sigmoid septa and left ventricular walls thinning. When the old patient in this condition suffer psychosomatic stress, catecholamines will be released, causing the hypercontraction of the left ventricle, the pressure difference in the chamber, and the collapse of the apical of the heart. We concluded that these physiopathological states may be responsible for the abnormal movements of the muscular walls of the heart peculiar to the disease taken up in this study.

Postoperative meningitis after spinal surgery is a rare complication that can result in a life-threatening condition. Linezolid (LZD) is an oxazolidinone which has been approved in Japan for infections caused by methicillin-resistant Staphylococcus aureus. The authors encountered a case of postoperative meningitis with cerebrospinal fluid leakage (liquorrhoea) that occurred after resection of a cervical cord tumor. The infection was caused by methicillin-resistant Staphylococcus epidermidis(MRSE). Debridement and suture of the dura matter was carried out. LZD was given intravenously. The infection was cured without any sequelae. Based on this result, we concluded that LZD might be considered as one of the first choices for the treatment of postsurgical meningitis caused by MRSE.

Lung cancer has a high mortality rate and is often diagnosed at the metastatic stage. Recently, gefitinib, a molecule target therapeutic drug, has offered a new approach for patients with non-small-cell lung cancer (NSCLC). This report describes the effects of gefitinib on bone metastases in two patients with NSCLC. The pain induced by a bone metastasis was relieved after the administration of gefitinib. Furthermore, the radiographs and CT findings showed sclerotic changes that matched those of the metastatic bone tumor after gefitinib administration in both patients. It is believed that gefitinib inhibited tumor cell proliferation and induced normal bone formation. In patients with NSCLC, gefitinib may be effective in the treatment of bone metastases.

STUDY DESIGN: A case-series study. PURPOSE: To assess the long-term clinical and radiographic outcomes after vertebroplasty using calcium phosphate cement (CPC) for treatment of osteoporotic vertebral fractures (OVF). OVERVIEW OF LITERATURE: Vertebroplasty has become common for the treatment of OVF. However, few studies have reported the clinical application of CPC to vertebroplasty. METHODS: We reviewed 86 consecutive patients undergoing 99 vertebroplasties using CPC. Following repositioning and curettage of the pathological soft tissue of the vertebral body (VB), vertebroplasty using CPC was performed in patients with osteoporotic burst fracture and pseudoarthrosis (procedure A). Vertebroplasty was also performed in patients with osteoporotic compression fractures (procedure B). Back pain and lower back pain were evaluated using the visual analogue scale (VAS). The VB deformity index was measured in a lateral radiograph as the ratio of the VB's height to its longitudinal diameter. RESULTS: The mean age at time of surgery was 77 years old. The mean duration of follow-up was forty-four months. All patients reported decreased pain according to the VAS immediately after vertebroplasty, and pain relief was maintained at the last follow-up in all patients without new OVFs. Complete bone union was observed in all cases by six months after surgery. The mean recovery rate of deformity index was 5.9% in procedure A and 0.02% in procedure B at the final follow-up visit. CONCLUSIONS: Vertebroplasty using CPC gave a satisfactory outcome and no delayed complications in elderly patients with osteoporotic vertebral fractures at follow-up times of at least two years.

PURPOSE: Small bowel obstruction (SBO) remains a common complication after pelvic or abdominal surgery. However, the risk factors for SBO in ulcerative colitis (UC) surgery are not well known. The aim of the present study was to clarify the risk factors associated with SBO after ileal pouch-anal anastomosis (IPAA) with a loop ileostomy for patients with UC. METHODS: The medical records of 96 patients who underwent IPAA for UC between 1999 and 2011 were reviewed. SBO was confirmed based on the presence of clinical symptoms and radiographic findings. The patients were divided into 2 groups: the SBO group and the non-SBO group. We also analyzed the relationship between SBO and computed tomography (CT) scan image parameters. RESULTS: The study included 49 male and 47 female patients. The median age was 35.5 years (range, 14–72 years). We performed a 2- or 3-stage procedure as a total proctocolectomy and IPAA for patients with UC. SBO in the pretakedown of the loop ileostomy after IPAA occurred in 22 patients (22.9%). Moreover, surgical intervention for SBO was required for 11 patients. In brief, closure of the loop ileostomy was performed earlier than expected. A multivariate logistic regression analysis revealed that the 2-stage procedure (odds ratio, 2.850; 95% confidence interval, 1.009–8.044; P = 0.048) was a significant independent risk factor associated with SBO. CT scan image parameters were not significant risk factors of SBO. CONCLUSION: The present study suggests that a 2-stage procedure is a significant risk factor associated with SBO after IPAA in patients with UC.
