This paper deals with a case which was firmly diagnosed as ileum perforation caused by an ingested fish bone during an emergency operation for acute appendicitis.
A 49-year-old man was referred to our hospital because of right lower abdominal pain. On close exploration, acute appendicitis was suspected, and an emergency laparotomy was performed. During the operation, we confirmed redness and swelling of the appendix, thickening of the mesoappendix, and typical presentations of appendicitis. Moreover, there was massive retention of blood in the small intestine, and an intestine about 20cm from the terminal ileum was adherent to the inside of the right common iliac artery. When the adhesion was dissected, a fish bone was detected. From these findings, it was thought that iliac perforation due tothe fish bone had involved the appendix. Appendectomy and a partial excision of the ileum were performed.
It was inferred that, since the patient had previously undergone a total gastrectomy with Roux-en Y reconstruction, there was no secretion of gastric juice, resulting in poor digestion of the fish bone. Though the fish bone could be easily evacuated to the small intestine because of a lack of physiological barriers such as the pyrolic ring, it was considered, the perforation occurred because of astricture of the intestine caused by adhesion.

Introduction: We experienced a case of pneumatosis cystoides intestinalis with intra-abdominal free air following steroid therapy for an end-stage brain tumor. Case: The patient was a 67-year-old man. He had received surgery and chemotherapy for the brain tumor, but the disease progressed and his consciousness deteriorated. Eventually, he developed aspiration pneumonia and was hospitalized. His consciousness level remained poor even after the pneumonia improved. His survival prognosis was considered to be approximately 1 month, and he was transferred to a palliative care ward. After the transfer, administration of betamethasone 8 mg/day was started for the purpose of improving his level of consciousness. Temporary improvement was observed, and administration of this drug was continued with dose adjustments, as appropriate. Six weeks after the start of betamethasone administration, when his consciousness level again deteriorated, aspiration began to recur. Chest X-rays, obtained to assess pneumonia, showed intra-abdominal free air. Pneumatosis cystoides intestinalis was confirmed by computed tomography. He had few abdominal symptoms, and was managed conservatively. He died of respiratory failure. Conclusion: Pneumatosis cystoides intestinalis is mostly secondary, and steroid therapy is considered to be one of the causes. But follow-up observation is often conservative, and judgment of discontinuation of steroid needs to be made in consideration of its effect and prognosis is there.

We set out to assess our treatment strategy of acute aortic dissection associated with atherosclerotic aortic aneurysm, and to assess its results. A total of 228 patients with acute aortic dissection were admitted to our hospital between 1994 and 2009. Among these, 30 cases were associated with atherosclerotic aortic aneurysm and we retrospectively analyzed their patient data. Of these, 5 patients received diagnoses of Stanford A dissection and 25 patients demonstrated Stanford B. Coexisting aneurysms consisted of postabdominal aortic replacement in 9 patients, ascending aortic aneurysm in 1, arch aortic aneurysm in 6, descending aortic aneurysm in 2, thoracoabdominal aortic aneurysm in 3, and abdominal aortic aneurysm in 9. Patients were divided into 3 groups based on the relationship between aneurysm and dissection : acute aortic dissection occurred after graft replacement of an aortic aneurysm (Group 1, n=9), dissection coexisted with aneurysm in a different segment of the aorta (Group 2, n=8), and dissection extended to or involved the aneurysm (Group 3, n=13). Our treatment strategy for all patients excluding those with aortic rupture or malperfusion is described below. In the cases of Stanford A dissection, emergency ascending aortic replacement or total arch replacement was performed. In cases of Stanford B, patients were treated conservatively in the acute phase. Surgery for the coexisting aortic aneurysm was then performed in the chronic phase, if the aneurysm was large. We think that the interval between dissection onset and aneurysm surgery should be extended to at least 1 month, because the aortic wall was too fragile to perform anastomosis in the acute phase in the present cases. As a result, there were 2 hospital deaths in Group 3, but there was no aortic rupture during treatment in the acute phase in any of these 3 groups. There were no vascular-related deaths during follow up. Our treatment strategy obtained favorable outcomes.

A case of 38-year-old woman with corrected transposition of great arteries is reported. She was admitted for acute cardiac failure caused by not only the left-side atrioventricular regurgitation for the ruptured chordae tendineae, but also the right-side one. We have to perform double valve replacement emergently due to the progression of biventricular failure. Very few reports have described a surgical repair of the right-sided valve replacement. The postoperative course was favorable.

We worked out TTR values in patients receiving warfarin treatment in Abashiri-Kosei General Hospital. The patients were divided into two groups - those with satisfactory TTR values and those with poor TTR values - and associations between patient factors and average dosing interval were examined in the two groups. A total of 178 patients joined this study. The average TTR value worked out at 65.1±24.8%. It was found that the average TTR value for those patients aged at 70 and above came to 72.7±21.4%, which was significantly high as compared with 51.06plusmn;24.6% for those under 70 years of age. When the average TTR value was calculated after the optimal PT-range for the group of those below the age of 70 was changed from 2.0~3.0 to 1.6~2.6, it rose from 51.0% to 74.9%. These findings made it clear that PT-INR, regardless of age, was under control within the range from 1.6 to 2.6 in this hospital in accordance with the results of the J-RHYTHM Registry analysis.

The World Health Organization (WHO) recommends antimicrobial use density (AUD) as an indicator for evaluating the amount of antimicrobials used, an index that is now widely employed in many facilities. Defined daily doses (DDD) set by WHO are used for calculating AUD. However, discrepancies have been noted between other countries and Japan in the standard dosage of antimicrobials, which may cause a problem evaluating antimicrobial use with the DDD. Therefore, in this study, we calculated AUD (modified antimicrobial use density: mAUD) with the DDD (modified defined daily dose: mDDD) of our hospital for the carbapenem antimicrobial meropenem (MEPM), mAUD, and resistance rate of Pseudomonas aeruginosa. From 2010 through fiscal year 2016 (ending in March), AUD was 5.9±1.4, 7.0±2.9, 8.2±2.3, 6.8±2.1, 7.3±2.2, 7.0±2.1, and 8.0±3.0 and mAUD was 11.7±2.7, 12.0±4.9, 11.3±3.1, 11.0± 3.4, 11.4±3.5, 11.5±3.5, and 11.2±4.2, respectively. The corresponding resistance rate of P. aeruginosa was 35.1%, 37.9%, 10.0%, 6.0%, 22.6%, 10.6%, and 10.0%. A significant positive correlation was found between mAUD and the resistance rate of Pseudomonas aeruginosa (P < 0.01, r = 0.88). Our results confirm that the mAUD is an effective index for controlling resistance of P. aeruginosa.

PURPOSE : To determine risk factors for excessive sensitivity to cold (ESC) in relation to physical features.DESIGN : A prospective cohort study carried out between July 7 and November 14,2008.PARTICIPANTS AND METHODS : Seventy female junior college students with no ESC at baseline, and a median age of 20 years, participated. We used a numerical rating scale (NRS) to classify each ESC sensation over the five days in this July-November period.To confirm physical symptoms, we used Terasawa's diagnostic scores for ki, ketsu, and sui. We defined ESC as mean NRSgeq ≥ 5.RESULTS : We documented 17 participants with ESC in November. The multivariate adjusted odds ratio for ESC was11.6 (95% CI 1.9 to 97.5) for the physical characteristic “edema”. Participants with ESC were shorter in stature than participants without ESC (-5.9cm ; 95% CI -8.6 to -3.1).CONCLUSION : Participants with edema and short stature have a high risk for ESC.

A 72 year-old man underwent coronary angiography (CAG) with a diagnosis of unstable angina pectoris, and 90% stenosis of the LMT was found. Since idiopathic interstitial pneumonia (IIP) had been diagnosed previously, percutaneous transluminal coronary angioplasty (PTCA) was performed. However, his unstable angina recurred after about 2 months restenosis of the LMT to 90% was shown by CAG, and coronary artery bypass grafting (CABG) was performed. In the preoperative chest X-ray, diffuse granular opacities were seen in both lower lungfields, and Velcro rales were heard by ausculation. A spirogram could not be obtained because of his unstable angina, but the PaO2 was a reasonable 70mmHg when breathing room air. In consideration of the age of the patient, a double coronary artery bypass grafting using a saphenous vein graft (SVG) was performed to minimize duration of anesthesia. His PaO2 showed a transient decrease after the end of cardiopulmonary bypass (CPB), but the perioperative hemodynamics and respiratory status were stable and extubation was performed on the 1st postoperative day. No aggravation of his IIP occurred postoperatively and he was discharged on the 29th postoperative day.

A total of 961 patients underwent coronary artery bypass grafting (CABG) between 1982 and 1991, and we investigated perioperative cerebral infarction. The average age of operation in these case was 65±4 years. There was 9 patients with hypertension, 7 with diabetes mellitus and 5 with hyperlipidemia. Concerning cerebral infarction, there were 3 patients with multiple infarction, 6 with infarction of the mid cerebral artery area, 1 with infarction of posterior cerebral artery area, 1 with infarction of posterior cerebral artery area, 1 with infarction of pons and 1 with infarction of the ophthalmic artery. The courses of infarction involved atherosclerosis, hypoperfusion during cardiopulmonary bypass, thrombosis due to arterial fibrillation and thrombus on the left ventricular wall. Three patients who had critical cerebral infarction died after CABG. We consider that avoid perioperative cerebral infarction preoperative atherosclerosis, thrombus and to choose the proper procedure of the operation.

Coronary artery bypass grafting using hypothermic circulatory arrest and ventricular fibrillation without aortic cross clamping in 6 patients with severely calcified aortas is described. The use of hypothermic circulatory arrest or ventricular fibrillation has not been established in coronary artery bypass grafting. We recently used aortic no-touch technique in 6 patients. All patients were supported and cooled with cardiopulmonary bypass, and circulatory arrest was performed in 3 patients. With the exception of one hemodialysis patient, 5 patients survived without neurological deficit. We think the aortic no-touch technique is safe and reliable in coronary artery bypass grafting with severe calcified aortas.
