A Case of Incomplete Atypical Femoral Fracture with Histomorphometrical Evidence of Osteomalacia

Roughly half of the femoral fracture patients diagnosed with AFF according to the criteria suggested by a task force of the American Society for Bone and Mineral Research (ASBMR) have not undergone bisphosphonate (BP) therapy. One suspected cause of such fractures is severe bone loss due to osteomalacia, but the pathogenesis remains unknown. We report a case of an 84-year-old woman with AFF not treated by BP therapy, in whom underlying osteomalacia was histologically diagnosed. The involvement of femoral curvature and spino-pelvic malaligment in the fracture in the present case was considered

ファロー四徴症に対する直視下右室流出路拡大術の検討

Fourteen cases of TOF were performed on the RVOT construction without closure of the VSD which was called central palliation. The cases consisted of an equal number of males and females. These patients ranged in age from six to forty-five years. Before central palliation, initial palliative shunt was carried out in five cases. The remaining nine cases were provided with the central palliation as the initial surgery. Twelve cases showed the ratio of PA/AO below one fourth or the ratio of RPA/AO below 0.3. Two cases showed an abnormal right coronary traversing the right ventricle. Resection of the abnormal right ventricle muscle band and pulmonary valvuloplasty were performed in nine cases (group A) and the placement of a patch graft was done in five cases (group B). Arterial oxygen saturation was increased in both groups postoperatively. The postoperative hematocrit was decreased in both groups. Postoperative PA/AO ratio became 1/3 in group A and 1/2.3 in group B, respectively. Symptomatic improvement was good, especially in group B. The preoperative state of group B patients was classified as NYHA functional class IV. After central palliation, four cases changed to NYHA functional class II and one case could not be located during the follow up period. Determination of the proper time for central palliation correction remains a problem that must be solved in the future. The time necessary for total correction will be about three or four years with occasional observation and follow up

Influence of oxygen in inflation gas during lung ischemia on ischemia-reperfusion injury

AbstractObjectives: Previous studies have reported that hyperinflation during lung ischemia improves pulmonary function after reperfusion. However, it has not been clarified whether hyperinflation itself or oxygen in inflation gas causes good pulmonary function. The aim of this study is to evaluate the effect of oxygen in pulmonary inflation gas during lung ischemia on ischemia-reperfusion injury. Methods: Twenty-one mongrel dogs were randomly divided into three groups: the lung during a 90-minute period of warm ischemia was inflated to 30 cm H2O with 100% oxygen in group A and 100% nitrogen in group B; it was not inflated in group C. Pulmonary function and hemodynamics were measured before ischemia and 1,2, and 3 hours after reperfusion. Total protein and phosphorous of phospholipid in bronchoalveolar lavage fluid were measured 210 minutes after reperfusion. Results: No significant differences in pulmonary function and hemodynamics were noted between group A and group B, but these two groups had significantly better pulmonary function and hemodynamics than group C. No significant differences were detected in the concentrations of total protein and phosphorus of phospholipids in bronchoalveolar lavage fluid and in adenine nucleotide levels of lung tissue after reperfusion among the three groups. Conclusions: The results indicate that pulmonary inflation during warm ischemia improves pulmonary function and hemodynamics after reperfusion in this model. The effect is caused by inflation itself and is not due to oxygen as a metabolic substrate during warm ischemia. (J Thorac Cardiovasc Surg 1997;114: 332-8

高齢者(70歳以上)弁膜症に対する外科治療成績と遠隔成績について : 70歳以上と60-69歳における臨床成績と血行動態の検討

Results of open heart surgery in 22 consecutive elderly patients aged 70-76 are presented and compared with results of that procedure in 135 younger patients aged 60-69. The elderly patients presented with valvular disease between August 1, 1987, and September 30, 1994. They consisted of 12 men and 10 women with a mean age of 72.3 years. Fifteen of 22 patients had isolated aortic valve replacement (AVR) or mitral valve replacement (MVR) or repair and 7 patients had combined two or three surgical procedures; 14 of them underwent AVR, 8 underwent MVR or repair, 3 had both mitral and tricuspid valve repair and 2 had coronary artery bypass graft. Preoperatively 54.5% of the patients were in NYHA functional class III and 27.3% were in class IV. Mechanical and biological valves were replaced in 10 and 12 patients, respectively. Preoperative organ dysfunctions in the present patients were associated with the heart in 32%, the lung in 18%, the liver and kidney in 9% and the gastro-intestinal tract in 18%. The only significant correlation between pre and postoperative organ dysfunction was noted in the lung. The younger group averaged 64.2 years old at the time of surgery. Preoperative hemodynamic data in the aortic and mitral valve position indicated lower pressure and LV function in the elderly group than in the younger group, but there were no significant differences between the groups before and after surgery except for in the mean values of m-PCWP in AVR and m-PAP in MVR, which were also significantly improved in the younger group after surgery. The operative mortality rates were 9.1% for elderly patients and 3.0% for the younger patients. Late follow-up of 20 survivors was 86.4±2.9% in the elderly and 82.7±3.9% in the younger patients. There were one late death (1.5%) in the elderly and 10 late deaths (7.4%) in the younger groups. The incidences of freedom from valve-related morbidity were 1.2%/pt-y with 94.7±2.9% being event free in the elderly group and 1.9%/pt-y with 92.4±4.1% being event free in the younger group; these showed no significant differences. These early and long-term results indicate that valve surgery in the elderly has acceptably low mortality and morbidity, and overall survival rate and improvements in symptoms and functional class are comparable to those of younger patients

大動脈弁置換術における冷却血液心筋保護液を用いた順行性と逆行性冠灌流法の比較検討 : 術後の血行動態,左右心室機能および心筋逸脱酵素値からみた心筋保護効果の検索

A total of 50 patients undergoing isolated aortic valve replacement received either aortic root (anterograde 〔AGC〕: 25 patients) or coronary sinus (retrograde 〔RGC〕: 25 patients) perfusion with cold blood cardioplegic solution and were compared. The groups were similar with respect to age, sex, preoperative NYHA Class, aortic cross-clamping time and mean dose of cardioplegic solution. There were no significant differences in low cardiac output syndrome, rhythm disturbances and surgical mortality between the two groups. There were also no significant differences in right ventricular stroke work and postoperative cardiac enzymatic levels after surgery in the groups. However, there was a significant improvement in left ventricular stroke work after RGC over that after AGC and significantly more inotropic agents were required with aortic root perfusion than with coronary sinus delivery of cardioplegic solution. These findings indicate that coronary sinus perfusion has benefits not only as a surgical technique but also better preserves the hypertrophied left ventricle more effectively than aortic root perfusion

Case Report Trigger Finger Appearing as Gradually Increasing Digital Nerve Disorder after Surgical Treatment

Trigger finger is a common disease, and operative treatments are often applied for it. Digital nerve injury is one of the complications of this surgical treatment, and paresthesia and sensory disturbance occur early after the operation. This paper presents a case of trigger finger appearing gradually as increasing digital nerve disorder after surgical treatment. In the second surgery, scar tissue covered the palmar MP joint where the A1 pulley had existed before, and palmar digital neurovascular tissue of the ulnar side was found on the inside of the scar. The ulnar digital nerve showed swelling like a neuroma, and bilateral digital nerves existed nearer to the center of the flexor pollicis longus tendon than normal digital nerves. Even when we operate on trigger finger by open release, we should create an appropriate surgical space for observation and be careful of digital nerve injury
