We report a case in which an undernourished female patient underwent drainage for gingivitis, and
subsequently suffered S. intermedius-induced subdural abscess, meningitis and transverse sinus
thrombosis. A few days after drainage, she had a fever of 39°C and became lethargic with non-fluent
aphasia. Cerebrospinal fluid revealed pleocytosis of 1269/μl, protein 222 mg/dl (normal 15-45mg/dl),
glucose 33 mg/dl (ratio to blood glucose: 0.37). The diffusion-weighted MRI brain showed an area
of abnormally high signal along the left brain surface. In the magnetic resonance venography, the left
transverse sinus was not well delineated. After treatment with antibiotics (meropenem, vancomycin)
and heparin, craniotomy was performed to remove the abscess. Culture of the abscess tissue detected
S. intermedius. After surgery she gradually improved. To our knowledge, this is the first report of
subdural abscess and transverse sinus thrombosis caused by S. intermedius occurring as a result of
drainage treatment for gingivitis.

An attack of Raynaud's Phenomenon (RP) is characterized by blanching of the fingers in response to cold or emotional stimuli.
We analyzed the effect of ninjinyouei-to on RP in patients with MCTD. Subjects in this study comprised 19 patients, two males and 17 females, with a mean age of 38 years, and a mean duration of disease of 57.6 months. The study was performed at a time when RP occurred frequently in our country, that is in the period from November 1992 to March 1993.
We administered 9.0g of ninjinyouei-to to each case for four weeks and measured the surface skin temperature of the hands before and after medication with a thermograph using a Thermoviewer-JTG 3300.
There was a significantly higher temperature on the left first finger-tip after medication. Our thermographic findings in this study demonstrate a quantitative efficacy of ninjinyouei-to on RP in MCTD.

Twenty-two patients with chronic glomerulonephritis were treated with Sairei-to (7.5g/day), either alone or in combination with camostat mesilate (600mg/day), to determine the efficacy and adverse effects of these regimens. Although there was significant improvement in proteinuria (p<0.05) after 8 weeks of treatment with Sairei-to alone, this was not longlasting. Combination therapy resulted in sustained significant improvement (p<0.03; there were two dropouts). No adverse effects were seen with either regimen. The results suggest that combination therapy using Sairei-to and camostat mesilate may be a safe and efficacious method of treatment for patients with chronic glomerulonephritis.

In order to find an effective way to detect bacteria responsible for respiratory tract infections in children, we first examined as pharyngeal swabs, epi-pharyngeal swabs and nasal aspirates obtained from children hospitalized at our pediatric service during these five months from December 1997 to April 1998. In the rate of bacterial infection, it was found that nasal aspirates came out on top with 92.6%(25/27), followed by epipharyngeal swabs with 71.6%(53/74) and pharyngeal swabs with 26.2%(38/145). Single-species bacteria were found in 78.9%(30/38) of pharyngeal swabs, where as 45.3% of epi-pharyngeal swabs (24/53) and 52.0% of nasal aspirates (13/25) proved mixed infections with two-or three-defferent species. Thus it was suggested that nasal aspirates and epi-pharyngeal swabs would be far more adequate than pharyngeal swabs to detect bacteria with accuracy.
Next, based on the efficiency of bacterial detection, we compared culture media for the specimen obtained from in-patients and out-patients at our pediatric service. The rate of isolation of gram-negative rods was as low as 0.3%(1 of 314 strains) even when BTB agar plate, a selective medium for these bacteria, was employed. The sensitivety was not much different from those observed with nonselective blood agar plate. These results suggest that the conventional blood agar media can substitute for the more expensive type of BTB agar medium for the diagnosis of infections diseases of the airwaysin children.

The primary aim of this study was to compare the ratios of specialized palliative care use to all cancer death using 2 methods: 1) total number of patients who received either of specialized palliative care services (unadjusted), and 2) number of patients after adjustment of potentially duplicated counts (adjusted). The research team obtained patient list from all specialized palliative care services, and counted the number of the patients who received any specialized palliative care services. The ratio of adjusted value to unadjusted value was 0.59, and had large region differences.Unadjusted values had, although overestimated, essentially similar trends in changes by year and differences in the regions. In conclusion, total number of patients who received either of specialized palliative care services could be simple and feasible indicator to roughly determine the activity of specialized palliative care services, but exact number of the patients who received specialized palliative care services should be determined on the basis of the patient lists without duplicated counts.

At the Niigata University School of Medicine, objective structured clinical examinations (OSCEs) were performed for the first time in 2001 for 92 fourth-year medical students. The average evaluation scores students received from instructors were summarized, and the differences between scores given by different instructors were examined. We found that practice methods for the medical interview and physical examination before OSCE and the question topics and evaluation methods of OSCE were appropriate, but scores on some items were extremely low. The standardization and objectivity of the evaluation were satisfactory, perhaps because one explanatory conference and two training conferences were held for instructors before OSCE. However, some questions tended to produce differences between instructors, as did some topics, especially in the medical interview. The scores with standardized patients and those by teachers were strongly correlated, but those with the former were lower than those by the latter.

A study was conducted to investigate the influence on the shoulder joint of throwing during water polo. One hundred sixty-seven water polo players were interviewed about injuries caused by water polo, and 70 players claimed to have had shoulder pain.
In 21 players, clinical examinations were performed, and in 31 players, assessment of external rotation stability was made. Then three-dimensional analysis of hand-to-hand shoot motion was performed in 7 players.
The results were as follows;
1. The painful phases of the throwing motion were the take-back phase and the acceleration phase, the pain being present at the anterior and lateral portions of the shoulder joint,
2. Assessment of stability revealed that the external rotation displacement on the affected side was significantly larger than that on the control side in the injured players.
3. Analysis of hand-to-hand shoot motion revealed that the external rotation angle in the acceleration phase was significantly larger in non-injured subjects than in the injured.
4. The external rotation angle after ball contact was increased in the injured, but decreased in the non-injured.
5. To prevent injury, it appears important to catch and throw the ball using the upper extremity and rotation of the trunk in a high body position in the water, and to strengthen the muscles of the shoulder.

Electromyographic muscle activities of the shoulder muscles during shoulder external rotation with reference to load magnitude were studied in 8 healthy male subjects without history of shoulder injuries. In addition, we discussed the relationship between rotator cuff muscles and superficial muscles. The subjects performed shoulder external rotation from 60°internal rotation to 45° external rotation at 20° of shoulder abduction and 20° of flexion. A Cybex dynamometer used to prescribe angle and velocity of the shoulder movement. At the same time, intramuscular wire electrodes were inserted into the supraspinous, infraspinous and teres minor muscles, and then surface electrodes were placed over the posterior deltoid and middle trapezius muscles. The load magnitude ranged 2-18 Nm and the angle velocity was set at 15 deg/sec. The rotator cuff muscles became significantly to be activated from 2 Nm (the supraspinous and infraspinous m.) and from 4-5 Nm (the teres minor m.) compared with the muscle activity during non-load. The superficial muscles became significantly to be activated from 4-7 Nm (the posterior deltoid m.) and from 3-6 Nm (the middle trapezius m.) compared with the muscle activity during non-load. Within the load range (18 Nm 46.8% MVC), %iEMG of the rotator cuff muscles was always larger than that of the superficial muscles. Therefore, we concluded that the contribution of the rotator cuff muscles was larger than that of the superficial muscles up to 3-4 Nm, and activities of the superficial muscles increased gradually from 3-4 Nm during shoulder external rotation.

A case of a 51-year old male with pulmonary valve endocarditis accompanied by aortic regurgitation, and ruptured aneurysm of Valsalva sinus was reported. Repeated blood cultures grew α-streptococcus on a single occasion. After medical treatment, resection of pulmonary valve vegetation, resection and patch closure of aneurysm, and aortic valve replacement were performed successfully. Twenty one cases of pulmonary valve endocarditis reported in Japan, including our case, were collected and reviewed. Causative organism was streptococcus in 93% of cases. No case of intravenous drug abuse was found in this series. A variety of preexisting heart diseses were found in 20 cases out of 21 (95%). All these diseases were congenital ones, such as ven-tricular septal defect, patent ductus arteriosus, pulmonary stenosis and ruptured aneurysm of Valsalva sinus. This fact means that jet lesion of pulmonary valve is a major predisposing factor of pulmonary valve endocarditis. Surgical procedures were reported in 12 cases: resection of vegetation in 4 cases, resection of pulmonary valve in 2, and pulmonary valve replacement in 5. Appropriate surgical procedures should be chosen, depending upon the activity of infective endocarditis, severity of destruction of the valve, and pulmonary vascular resistance.
