Recently, the incidence of pulmonary embolism (PE) after surgery began to increase in Japan and to prevent PE has become essentially important. During the period between July 2003 and August 2004, we placed 203 general surgical patients under our perioperative management using intermittent pneumatic compression (IPC) and compression stockings (CS). We evaluated the effect of our management on the prevention of postoperative PE in those patients. The incidence of PE, prognosis, complications, patient's complaints, cost-benefit were examined. No fatal PE occurred. One patient with low SpO2 had a chest pain and dyspnea but pulmonary scintigrams revealed no PE. Two other patients had contact dermatitis by CS and another patient using an epidural catheter suffered temporary paraplegia after heparin injection. The government has approved a fee for PE prophylaxis since April 2004. Our management using IPC and CS for PE prophylaxis after surgery proved to be an effective in reducing the risk of PE. However, we must take the atmost care in injecting heparin into patients with epidural catheters.

We encountered a probable case of loiasis in a returned traveler from Central Africa. A 52-year-old Japanese woman presented to our hospital complaining of discomfort in her eyes and skin. She reported having frequently visited Central Africa over many years and having been extensively exposed to the rainforest climate and ecosystem. Although no microfilariae were found in her blood, there was an elevated level of IgG antibodies against the crude antigens of Brugia pahangi, which have cross-reactivity with Loa loa. She was treated with albendazole for 21 days, after which the antigen-specific IgG level decreased and no relapse occurred.

A 14-year-old women who had a history of aortic root replacement at 7 years old admitted our hospital due to dilatation of aortic arch aneurysm. Loeys-Dietz syndrome was diagnosed when she was 10 years old. Computed tomography showed 70 mm proximal arch aneurysm. Operative findings revealed brachiocephalic artery and left common carotid artery branched from aneurysm. Partial arch replacement was performed and distal anastomosis was made between left common carotid artery and left subclavian artery. Close observation by CT regularly is necessary and undergo aortic repair not to miss the timing of surgery.

STUDY DESIGN: Animal study. PURPOSE: To review the present warning point criteria of the compound muscle action potential (CMAP) and investigate new criteria for spinal surgery safety using an animal model. OVERVIEW OF LITERATURE: Little is known about correlation palesis and amplitude of spinal cord monitoring. METHODS: After laminectomy of the tenth thoracic spinal lamina, 2-140 g force was delivered to the spinal cord with a tension gage to create a bilateral contusion injury. The study morphology change of the CMAP wave and locomotor scale were evaluated for one month. RESULTS: Four different types of wave morphology changes were observed: no change, amplitude decrease only, morphology change only, and amplitude and morphology change. Amplitude and morphology changed simultaneously and significantly as the injury force increased (p<0.05) Locomotor scale in the amplitude and morphology group worsened more than the other groups. CONCLUSIONS: Amplitude and morphology change of the CMAP wave exists and could be the key of the alarm point in CMAP.

Methods: The study included 100 patients with cervical myelopathy who underwent surgery at the National Center for Geriatrics and Gerontology in Obu, Japan from June 2010 to March 2013. Before the surgery, neck pain was evaluated using a Visual Analog Scale (a score ≥50 indicated neck pain and a score <50 indicated no neck pain). The preoperative cross-sectional areas of the trapezius muscles were measured with cervical magnetic resonance imaging sagittal T2-weighted images. Cranial stimulation under general anesthesia was used to derive the MEPs, enabling the measurement of latency and amplitude, using preoperative MEPs of the trapezius muscles. Results: The MEP of the trapezius muscle in patients with neck pain had significantly shorter latencies than those in patients who did not have neck pain. However, there was no significant difference in the amplitude between patients with and without neck pain. However, this tended to be greater in patients with neck pain as compared to that in those without neck pain. The cross-sectional area of the trapezius muscle in patients with neck pain was significantly smaller than that in those who did not have neck pain. Conclusions MEPs revealed electrophysiological abnormalities of the trapezius muscles in patients with neck pain, supporting a relationship of neck pain with the trapezius muscles.

BACKGROUND/AIMS: Changes in lipid profiles in patients infected with hepatitis C virus (HCV) during direct-acting antiviral therapy have been reported in recent years. However, the clinical aspects of disturbed lipid metabolism in chronic HCV infection have not been fully elucidated. METHODS: Dynamic changes in serum total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol and apolipoprotein levels in patients infected with HCV genotype 1b were examined during combination therapy with daclatasvir (DCV) and asunaprevir (ASV). RESULTS: Total, LDL−, and HDL-cholesterol levels increased rapidly and persistently after week 4. Apolipoprotein (apo) A-I, apo B, apo C-II, and apo C-III levels were significantly higher at week 4 than at week 0. In contrast, apo A-II and apo E levels were significantly lower. The differences in LDL− and HDL-cholesterol levels were positively correlated with those of apo B and apo A-I, respectively. Interestingly, in patients with non-sustained virological response, these cholesterol levels decreased rapidly after viral breakthrough or viral relapse. Furthermore, similar changes were observed for apo A-I, apo B and apo C-III levels. CONCLUSIONS: Clearance of HCV using combination therapy with DCV and ASV results in rapid changes in serum lipid profiles, suggesting an influence of HCV infection on disturbed lipid metabolism.

Introduction: Recently, doping among athletes has been on the rise, and pharmacists have an important role in both the promotion of anti-doping (AD) and in providing accurate information and effective support. In this study, we examined various fact-finding surveys that targeted physical education university (PEU) students, and we focused on their use of pharmacies/drugstores, their involvement with pharmacists, and knowledge about AD. We also examined the necessary AD-related professional competencies of pharmacists. Method: Questionnaire surveys were prepared, and the responses of 1,249 students were analyzed. Results : From a survey on what students buy at pharmacies/drug stores it showed that medicines for flu common colds sell the most. Most of the students did not receive any drug consultations at pharmacies/drug stores before purchasing, because they preferred to make their own decisions about drug use. Also, many students were wary of doping with supplements. Although the students who participated in international sports competitions and events possessed a wealth of doping-related knowledge and awareness, PEU students lacked them. Discussion : We determined that it was necessary to gather relevant patient information and explore methods so that intentions could be discussed when purchasing medications from pharmacies/drug stores. We also recognized the need for early doping education programs in light of the inadequate AD-related knowledge and awareness among university student-athletes. Therefore, all pharmacists should strive to acquire a wide range of knowledge to support athletes in this effort. Furthermore, we believe that expanding the professional functions of pharmacists would increase the awareness of AD among athletes.

A 60-year-old man underwent aortic valve replacement for aortic valve regurgitation, tricuspid valve annuloplasty, and coronary artery bypass grafting. Postoperative echocardiography revealed shunted flow from the noncoronary sinus of Valsalva into the left atrium. The pathogenesis of this complication is considered to be uncertain ; however, it might be due to some kind of intraoperative injury. Three weeks after the initial surgery, we reoperated to repair the aorto-left atrial fistula. According to the intraoperative findings, small slits were found on the left atrial surface close to the posteromedial side of the mitral valve and the noncoronary sinus of Valsalva. The fistula was closed with transmural mattress sutures. Post-operative echocardiography showed no shunt flow. Although an aorto-left atrial fistula is a rare complication after aortic valve replacement, reoperation might be mandatory if the shunt flow is considerable. Surgeons should keep in mind the possibility of intraoperative injury to surrounding structures when performing aortic valve replacement.
