Here we report the results of a long-term analytical study on the utilization of antihypertensive and antibacterial agents, which was performed using the Integrated Medical Information System (IMIS) developed by Kochi Medical School. The results indicate clear (increasing or decreasing) patterns in the numbers of patients and the dosages. Specifically, the total amount of antibacterials recently prescribed is significantly lower than in the year analysis began (1983). This reduction provides evidence of a steady improvement in the quality of medication and is particularly important for macrocosmic evaluation of the primary focus of our study, which was the “proper use of drugs”. Furthermore, the results also showed medication prescribed by non-specialists to be less inventive than that prescribed by specialists. This study highlights the importance of reforming institutions providing medical treatment from the perspective of effectively utilizing medical resources (by employing specialist personnel) and the proper use of medications. Because non-specialists prescribe medication in numerous medical facilities throughout Japan, these issues must be seriously considered.

Garré's osteomyelitis is generally considered to be synonymous with chronic osteomyelitis with proliferative periostitis and occurs most commonly in the first molar region of the mandible. We report a case of Garré's osteomyelitis caused by the infected tooth-germ of a wisdom tooth. A 12-year-old boy had a swelling of the right cheek and his right mandibular second molar was covered by gingiva with pus retention. X-ray examination showed a radiolucent area around the impacted tooth-germ of the wisdom tooth and extracortical new bone at the angle of the mandible. After preoperative treatment with antibiotics, the tooth-germ and extracortical bone were removed. The antibiotics treatment was continued for 18 days postoperation. No recurrence of pain or swelling has been observed thereafter.

In order to reduce the blood transfusion volume in open heart surgery, the new blood autotransfusion technique using cardiotomy reservoir unit BCR 3538, which was configured to serve also as a receptacle for postoperative mediastrinal drainage, was introduced. To investigate the utility and the problem in this system, every clotting factor, platelets' function and the extent of the hemolysis were measured serially both in patients' arterial blood and the shed mediastinal blood. The bank blood transfusion was significantly reduced to 250ml±330ml by this system compared to the 1080ml±820ml in the cases of usual system (p<0.01). Every clotting factor recovered well in patients' arterial blood after cardiopulmonary bypass (CPB). In the reservoir blood, the clotting factor IX, XI, XII were extremely suppressed at 1h CPB, and 3h after the CPB, every clotting factor except fibrinogen (42±28mg/dl) showed the quite higher activity, such as factor VIII 400%, IX 365%, XI 72%, XII 267%. Namely, the anticoagulability of the reservoir blood was maintained due to the effect of the residual heparin at 1h after the CPB, and due to the contact defibrinogation of the shed mediastinal blood at 3h after CPB. The free hemoglobin level was extremely high on the reservoir blood at 3h after CPB. In 6 cases, the autologous blood retransfusion was abandoned by clott formation in the unit because of the contamination of the intraoperatively used fibrin glue. From this study, the autologous blood transfusion using cardiotomy reservoir BCR 3538 was useful not only for saving the transfusion of the bank blood but also the hemostasis after CPB. But to reduce the hemolysis in this system, and to establish the safety against the other clotting material such as fibrin glue were the problems which should be resolved in future. I appreciate the kind support of Alexander von Humboldt Foundation for this study.

Gastro-esophageal reflux (GER) is a common and serious complication in patients receiving enteral nutrition, making continuation of enteral nutrition difficult. Semi-solid enteral nutrients were developed to prevent feeding-related GER. Semi-solid enteral nutrients have high viscosity and, therefore, are typically administered through a large-diameter percutaneous endoscopic gastrostomy (PEG) tube. Recently, a new formula (Mermed®, Mermed Plus®) was introduced that uses alginate, which behaves like a gelatin in acidic conditions. This formula improved GER during enteral feedings. Our case report shows that this new formula enables the continuation of enteral nutrition via a nasogastric tube (NGT) in patients with difficulty tolerating enteral nutrition secondary to vomiting. An 86-year-old woman with an atherothrombotic cerebral infarction vomited during tube feeding, resulting in aspiration pneumonia. After 1 week, we introduced a viscosity regulator and restarted enteral feeding using a 100 mL liquid diet, but vomiting persisted. Because of the continued difficulty in tolerating enteral nutrition, the patient was transferred to our hospital. From hospital day 4, Mermed Plus® (300 mL/225 kcal, administered for 1 hour, 3 times a day) was started, eventually increasing to 535 mL/400 kcal at hospital day 5. After this, vomiting ceased. Mermed Plus® was easily administered via NGT, and its effects were immediate. This treatment appeared to improve the patient's quality of life while reducing the burden on medical staff.

Secretory immunoglobulin A (s-IgA) in saliva constitutes the first-line barrier to the entry of pathogens into the body, implying its critical role in mucosal immunity.To examine the effect of a shark liver oil (SLO)-containing diet on salivary s-IgA concentration in healthy male and female adults, 42 subjects were assigned to either placebo or 6 weeks of a 2,400 mg SLO-containing diet (1,500 mg as SLO) and assessed in a randomized, double-blind, placebo-controlled, parallel group trial.Salivary s-IgA concentration significantly increased at week 6 in the SLO group (P = 0.033), but not in the placebo group.Moreover, there was a significant difference between groups in the magnitude of change from baseline to week 6.No intervention-related adverse event or abnormal changes of laboratory test parameters were observed throughout the study period.In conclusion, an SLO-containing diet increases salivary s-IgA in healthy adults.

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.
