Accessory nerve neurotization in infants with brachial plexus birth palsy

We report the surgical results of 13 accessory nerve neurotizations in brachial plexus birth palsy. The mean age at operation was 5.9 months. The accessory nerve was transferred to three C5 roots, to three C6 roots, to four posterior division of the middle trunks, to one musculocutaneous nerve, and to two suprascapular nerves. Sixty-seven percent of the cases acquired M4 or more in the deltoid muscle, 88% in the infraspinatus muscle, and 100% in the biceps brachii muscle. Twenty-five percent of the cases acquired M4 or more in the triceps brachii muscle and the wrist extensor muscles. These results were much better than formerly reported for adult cases by other authors. No functional compromise of the trapezius muscle was noted. The accessory nerve neurotization can be used safely and effectively in neurosurgical reconstruction of the brachial plexus palsy in infants. © 1994 Wiley-Liss, Inc.     

Intraosseous ganglion about to cause a fracture of the glenoid: a case report

Intraosseous ganglia of the glenoid are rare, and their etiology is unknown. This report describes a case of an intraosseous ganglion about to cause fracture of the glenoid. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. Her symptoms did not improve after non-operative treatment. Arthroscopic examination showed a cartilage defect and erosion in the posteroinferior portion of the glenoid, behind which computed tomography (CT) showed a cystic lesion of the glenoid. There was no communication between the cyst and the joint space. The patient was treated by curettage and an autogenous cancellous bone graft from the iliac crest. Two years after the operation, the patient was almost free from pain, and CT showed good integration of the bone graft.     

Anti-Candida albicans activity of essential oils including Lemongrass (Cymbopogon citratus) oil and its component, citral]

The effects of 12 essential oils, popularly used as antifungal treatments in aromatherapy, on growth of Candida albicans were investigated. Mycelial growth of C. albicans, which is known to give the fungus the capacity to invade mucosal tissues, was inhibited in the medium containing 100 micro g/ml of the oils: lemongrass (Cymbopogon citratus), thyme (Thymus vulgaris), patchouli (Pogostemon cablin) and cedarwood (Cedrus atlantica). Not only lemongrass oil but also citral, a major component of lemongrass oil (80%), in the range of 25 and 200 micro g/ml inhibited the mycelial growth but allowed yeast-form growth. More than 200 micro g/ml of citral clearly inhibited both mycelial and yeast-form growth of C. albicans. These results provide experimental evidence suggesting the potential value of lemongrass oil for the treatment of oral or vaginal candidiasis.     

Overestimation of myocardial viability due to an increase in thallium uptake by the lung

Thallium lung uptake (TL-uptake) was usually treated as background for myocardial image and increase of TL-uptake in exercise test was considered as marker of depressed cardiac function. It was reported that marked increase of TL-uptake in patients with acute myocardial infarction (AMI) corresponded to acute severe congestive heart failure. Here effect of TL-uptake on myocardial planar images was studied in 61 patients with AMI. In acute phase anterior, LAO 30 degrees and LAO 60 degrees myocardial images were collected. In 29 cases of 61 cases 3 to 6 hours delayed images could be collected. Each myocardial images was divided to 3 division and both images were compared. In 5 of 6 patients with marked increase of TL-uptake new defects were noted in anterior division of delayed images and in one case also in lateral division. In 7 patients of 12 patients with moderate increase of TL-uptake new defects were also noted in delayed images, i.e. 3 in anterior, 3 in inferior and one in apical division. It was concluded that over estimation of myocardial viability due to marked increase of TL-uptake was often noted in patients with AMI accompanying severe congestion. It became clear that delayed images were necessary to correctly estimate myocardial viability in such case.     

Clinical investigation of carbohydrate antigen CA-50

The CA-50 enzyme immunoassay kit (EIA kit) that has been developed with the use of C-50 monoclonal antibody prepared by L. Lindholm et al. was evaluated for diagnosis of human cancer. The levels of CA-50 in the sera were determined using this kit supplied from Mitsui Pharmaceuticals, Inc. Co. in 759 healthy donors, 728 patients with benign disease and 1,263 untreated patients with cancer. A CA-50 concentration of 40 U/ml of serum was used as the cut-off value. Patients with pancreatic cancer and patients with bile duct cancer had high positive incidence of 75% and 68%, respectively, compared with a low positive incidence of under 40% in patients with other cancers. On the other hand, positive rates in patients with benign disease were as low as 13%. Comparison of the serum levels of CA-50 with CA19-9 in the same samples did not exhibit complete positive correlation in patients with pancreatic cancer, patients with bile duct cancer and patients with liver cancer. These findings indicated that C-50 antibody reacted with two epitopes of CA19-9 and sialosyllactotetraose. From the above results, the usefulness of CA-50 as a tumor marker for pancreatic cancer and bile duct cancer was recognized with this EIA kit.     

Competitiveness in sports activities of the psychiatrically disabled]

In 2002, psychiatrically disabled athletes joined an historic first open game of volleyball at the national sports games for the disabled. Compared to the competitive sports and Paralympic Games that physically and intellectually disabled athletes have participated in, activities for the psychiatrically disabled have not been well-organized. In this paper, we examine a number of problems that have arisen when the psychiatrically disabled joined competitive sports games. We identify two major characteristics of the psychiatrically disabled of particular relevance when organizing competitive sports activities. First, all psychiatrically disabled athletes need treatment of their individual diseases. For example, psychiatric symptoms fluctuate markedly over time, unlike physical or intellectual disabilities, whose symptoms are much more stable. Exacerbations of psychiatric illness are also likely to occur due to the stresses of competitiveness. Second, psychiatric disabilities are manifestations of disorders in the central nervous system, which makes the classification of psychiatric disabilities less straightforward than classification of the physically disabled. These two characteristics require special attention when organizing competitive athletic challenges that include the psychiatrically disabled. However, promoting sports activities that include the psychiatrically disabled would be expected to reduce the prejudice toward and subsequent social disadvantages experienced by psychiatric patients. Thus, with careful planning to successfully integrate psychiatrically disabled athletes, we expect increased promotion of such sports activities in the future.     

An immunohistochemical study of MAP2 and clathrin in gerbil hippocampus after cerebral ischemia

Changes in MAP2 and clathrin immunoreactivity were studied in gerbil hippocampus after transient cerebral ischemia. MAP2 immuno-reactivity decreased significantly by 1 h in the subiculum-CA1 and CA2 areas which correspond to reactive change, while no decrease was observed in CA1 until day 4. Before the initiation of delayed neuronal death, MAP2 immunoreactivity was not changed in CA1. On the other hand clathrin immunoreactivity increased in the pyramidal cell layer of CA1 by 3 h after ischemia and remained high for 2 days. Clathrin immunoreactivity in the pyramidal cell layer of CA1 diminished after delayed neuronal death. The transient change of clathrin was noted especially in CA1 in the period prior to delayed neuronal death. These results imply an abnormal change in clathrin turnover after ischemia, which may participate in the pathogenesis of delayed neuronal death.     

Report of a patient of primary Sj?gren syndrome, IgA nephropathy and chronic idiopathic thrombocytopenic purpura]

We describe the case of a 61-year-old woman diagnosed with primary Sj?gren's syndrome (SS) after an 8-year history of IgA nephropathy and a 3-year history of recurrent purpuric rashes. Her two daughters had previously been diagnosed with other autoimmune diseases. One daughter had Graves' disease and the other had Hashimoto's disease and systemic lupus erythematosus. The diagnosis of SS was made based on dryness of mucous membranes, Shirmer test, and parotid sialography. Thrombocytopenia, high platelet-aggregated IgG (PA-IgG) level, and normal megakaryocytes count in bone marrow suggested that her recurrent purpuric rashes were due to idiopathic thrombocytopenic purpura (ITP). Patients with SS may develop other autoimmune diseases. This case aids understanding of the immune pathogenesis and genetic background of SS.     

Study on the mass-screening of after-meal serum triglyceride concentration]

The serum triglyceride concentration (TG) tested in health checks after meals cannot properly sort out hypertriglyceridemia with reference to the upper normal limit of fasting TG (150 mg/dl) set by the Japan Arteriosclerosis Society, because TG goes up considerably after a meal. In our survey of a large number of health check examinees (free of abnormal biochemical data other than TG and diseases under medical treatment), the mean (M) of fasting TG + 2 standard deviations (SD) was close to 150 mg/dl. When the screening level was set at M + 2SD for each time span after a meal, the ratio of the screened was distributed between 19.9 and 21.8%, which was close to 23.5%, the ratio of the screened on fasting. Accordingly, the nearest round number ending with zero for the first digit is suggested to be of practical use for the screening level of after-meal TG. The average TG in females was definitely lower than that of males, though proportionately increasing with age. The ratio of the screened among females aged between 20 and 49 was 5.3% on fasting and 3.2-5.8% for after-meal time spans, and that of the screened aged in their fifties was 11.3% and 8.2-12.9% respectively.
