A 74-year-old man had been taking warfarin for atrial fibrillation, but warfarin was discontinued due to upper gastrointestinal bleeding. One week later, left hemiplegia occurred, and cranial magnetic resonance imaging revealed multiple cerebral infarctions. Systemic examination revealed thrombi in both atria as well as duodenal cancer. Because all of the thrombi in both atria were larger than 30 mm in diameter, the risk of embolism or sudden death was assumed to be high. Although the use of cardiopulmonary bypass for cancer patients is controversial, bilateral atrial thrombectomy was performed 4 weeks after cerebral infarction onset because reasonable survival duration was expected with surgery for duodenal cancer after thrombectomy and further treatment. The timing of and indications for surgery in this case are discussed.

Objectives: To optimize the treatment of patients on tube feeding, it is important to ascertain whether medicines are appropriate for administration by gastrostomy and nasogastric tubes.  In this study, we evaluated the drug information services provided to medical staff by clinical pharmacists related to 109 patients administered medication via a feeding tube in a neurological ward.
Design and Methods: We analyzed the records of drug information services provided to medical staff from January 2006 to December 2007 at the Higashi Nagoya Hospital.  We classified drug information services for avoiding obstruction of the feeding tube and chemical changes into four categories: ‘formulation changes’, ‘medication changes’, ‘incompatibilities’ and ‘administration method’, and evaluated the acceptance rate of the pharmacists’ recommendations for drug therapy via feeding tube.
Results: Drug information related to formulation and medication changes accounted for 130 and 88 cases, respectively.  Information related to incompatibilities accounted for 19 cases, involving anticipated chemical changes related to concurrent administration of drugs.  Information related to administration methods accounted for 24 cases.  The acceptance rate for information by medical staff was 92.0%.
Conclusions: Drug information to medical staff by pharmacists contributes to improved safety for patients administered medication via feeding tubes.  The acceptance rate for drug information was high, and the provision of drug information by pharmacists in the neurological ward was considered useful.

Shoulder surgeons need to be aware of the critical size of the glenoid or humeral osseous defects seen in patients with anterior shoulder instability, since the considerable size of osseous defect is reported to cause postoperative instability. Biomechanical studies have identified the size of the osseous defect which affects stability. Since engagement always occurs between a Hill-Sachs lesion and the glenoid rim, when considering the critical size of the Hill-Sachs lesion, we have to simultaneously consider the size of the glenoid osseous defect. With the newly developed concept of the glenoid track, we are able to evaluate whether a large Hill-Sachs lesion is an "on-track" or "off-track" lesion, and to consider both osseous defects together. In case of an off-track Hill-Sachs lesion, if the glenoid defect is less than 25%, no treatment is required. In this case, the Latarjet procedure or arthroscopic remplissage procedure can be a treatment option. However, if the glenoid defect is more than 25%, treatment such as bone grafting is required. This will convert an off-track lesion to an on-track lesion. After the bone graft or Latarjet procedure, if the Hill-Sachs lesion persists as off-track, then further treatment is necessitated. In case with an on-track Hill-Sachs lesion and a less than 25% glenoid defect, arthroscopic Bankart repair alone is enough.

In the last decade, 78 patients received operations for abdominal aortic aneurysms with a transperitoneal approach (TP) while in 82 patients we used an extraperitoneal approach (EP). Forty-two patients in the TP group and 40 in the EP group who required no concurrent repair of the inferior mesenteric artery, renal artery or lower extremity arteries were compared. There was no difference between the two groups in mean operative time, mean amount of intraoperative bleeding or mean amount of required homologous blood transfusion. The mean interval after surgery to beginning peroral alimentation and the mean duration of postoperative fluid therapy were significantly shorter in the EP group than in the TP group. An extraperitoneal approach for abdominal aortic reconstruction is preferable for an early postoperative recovery.

Open surgery remains the treatment of choice for mycotic abdominal aortic aneurysm (MAAA). However, open surgery for MAAA is often associated with a significant perioperative risk and there have been some reports in which MAAA was successfully treated with endovascular aortic repair (EVAR). We report a case of MAAA treated with EVAR. Gallium scintigraphy was useful in postoperative evaluation of infection. A 61-year-old man presented with back pain. Computed tomography (CT) revealed a 50-mm saccular abdominal aortic aneurysm(AAA). The patient underwent EVAR for symptomatic AAA but developed a high fever 5 days after surgery. Serum C-reactive protein level was elevated and blood culture was positive for Salmonella. Intravenous antibiotics were commenced with a diagnosis of MAAA and the fever and inflammatory parameters subsided with a decrease in the size of the aneurysm. Accumulation of gallium was observed on scintigraphy 1 month after surgery. The patient received intravenous antibiotics for 8 weeks after surgery and was discharged home with oral antibiotics. At 6 months after surgery, accumulation of gallium disappeared. Oral antibiotics were ceased when CT showed disappearance of the aneurysm 9 months after surgery. At present, the patient has been doing well without signs or symptoms of recurrent infection.

We report two cases of an abdominal aortic aneurysm, one with congestive heart failure, and the other with a dissecting aortic aneurysm (type IIIb), who underwent an aorto-bifemoral bypass operation under a temporary external axillofemoral bypass. In one patient (Case 1, a 74-year-old male), who had an abdominal aortic aneurysm with congestive heart failure due to aortic valve insufficiency and stenosis, perioperative transesophageal echocardiography demonstrated that, with a temporary external axillofemoral bypass, the regurgitant doppler signal was unchanged during the cross-clamping period of the abdominal aorta. In the other patient (Case 2, a 71-year-old male), who had a dissecting thoracoabdominal aortic aneurysm with the lower abdominal aorta having a true aneurysm formation, the transesophageal echocardiography demonstrated that, with a temporary external axillofemoral bypass, the false lumen of the dissecting thoracic aneurysm had no change in size during the cross-clamping period of the abdominal aorta. Thus, a temporary external axillofemoral bypass might avoid any unfavorable hemodynamic effect during and after the abdominal aortic clamping in patients suffering from an abdominal aortic aneurysm with cardiovascular complications.

Approximately 80 % of medical students start medical training in a specific department at their medical school hospital after graduation and do not experience medical practices in other departments. Therefore, a questionnaire survey of conditions in and opinions about the present postgraduate clinical training was conducted among trainees at Osaka University Hospital. Questionnaires were returned by 136 of the 156 trainees (87.2 %). Their average income was ¥255, 000 per month. Approximately 85 % of trainees had less than 1 day's vacation each month. Forty percent of trainees were not satisfied with the present postgraduate clinical training course, because 75 % felt that their training life was too busy and did not allow them to observe a variety of diseases. These results suggest that the postgraduate medical training program in university hospitals should be changed to include various disciplines in several departments in cooperation with other hospitals and clinics for outpatients. To raise the quality of postgraduate medical training, an education system for trainees must be established and duties unrelated to medical examinations and treatment must be reduced.

To provide a better understanding of the local immune system in the face and external genitalia, i.e., the oral floor, lower lip, palpebral conjunctiva, anus and penis, we examined the distribution and density of CD1a-positve Langerhans cells, CD8-positive suppressor T lymphocytes and CD68-positive macrophages using specimens from 8 male elderly cadavers. The density of Langerhans cells showed an individual difference of more than (or almost) 10-fold in the lip (oral floor). In the oral floor, Langerhans cells were often spherical. Submucosal or subcutaneous suppressor lymphocytes, especially rich in the oral floor and penile skin, migrated into the epithelium at 4 sites, except for the anus. In the conjunctiva, macrophage migration into the epithelium was seen in all 8 specimens. The density of suppressor lymphocytes showed a significant correlation between the oral floor and the lip (r=0.78). In contrast, the anal and penile skins showed no positive correlation in the density of all three types of immunoreactive cells examined. Overall, irrespective of the wide individual differences, the oral floor and conjunctiva seemed to be characterized by a rich content of all three cell types, whereas the penile skin was characterized by an abundance of suppressor lymphocytes. Based on the tables, as mean value, the relative abundance of three different cell types were as follows; CD1a-positive Langerhans cells (anus), CD8-positive lymphocytes (penis), and CD68-positive macrophages (lip). The present observations suggest that the local immune response is highly site-dependent, with a tendency for tolerance rather than rejection.

Background: In the Latarjet procedure, the subscapularis is divided at the superior two-thirds junction. It has been believed that this subscapularis split approach resulted in better internal rotation strength rather than an L-shaped subscapularis tenotomy. However, there are few studies demonstrating the preserved function of the subscapularis after the Latarjet procedure. The aim of the present study was to clarify the subscapularis activity using positron emission tomography (PET) in patients after the Latarjet procedure. Methods: Six men who had undergone the Latarjet procedure were enrolled. The internal rotation exercise with elastic bands was performed with the arm at 0° and 90° of abduction. After the exercises, the patients had an intravenous injection of fluorine 18 fluorodeoxyglucose ( 18 F FDG). Each PET image was fused to the corresponding computed tomography image to calculate the standardized uptake value (SUV). The internal rotation muscle strength was measured by a dynamometer. Results: At 0° of abduction, the subscapularis SUVs of the involved side were significantly lower than those of the uninvolved side (p = 0.010), although there was no significant difference at 90° of abduction. The SUVs of the involved subscapularis were significantly lower at 0° of abduction than at 90° (p = 0.034). The internal rotation strength of the involved side was 81.1% ± 12.1% of the uninvolved side at 0° of abduction. Conclusions After the Latarjet procedure with the subscapularis split approach, subscapularis activity was well preserved at 90° of abduction. However, internal rotation strength was reduced by 19%.
