A 50-year-old man with chronic HCV infection had been received the injections of 12MU of Consensus-Interferon (C-IFN) three times a week in a previous hospital. Six months later, C-IFN therapy was terminated because of fever and massive ascites. Diuretics and antibiotics had not been effective against these symptoms. In the meantime, skin symptoms of purpura and giant ulcers in the extremities developed, and he was transferred to our hospital. Because skin biopsy revealed vasculitis and serum MPO-ANCA was positive, the diagnosis of ANCA associated vasculitis was made. Methylpredonizoron pulse therapy improved skin symptoms and massive ascites, and the skin ulcers eventually disappeared. ANCA is suggested to be responsible for this rare complication.

Whole blood or plasma glucose values were compared between those measured using various instruments for SMBG and automated analyses in samples (antecubital vein) from 20 approximately 70 years old obtained at cookie tests. A good correlation between values in whole blood SMBG and plasma automated analyses values greater than r = 0.94 was observed for instruments A, C, F, and H, and the per cent difference from the automated values was less than 5% for A, B, E and H. Per cent difference of SMBG values by I was -16% in whole blood and -9% in plasma, suggesting the possibility of measuring real values in whole blood. With plasma, a good correlation greater than r = 0.95 was noted for A, C, F and K, and the per cent difference less than 10% was noted for C, E, F and I. A relatively good correlation (r: 0.63 approximately 0.90) between forearm SMBG value and plasma automated values was noted with the % difference of the mean less than 11%. During cookie test, there is no significant difference between forearm SMBG values and antecubital plasma automated values. Values at finger tips are significantly greater by 5 approximately 20% over automated plasma values. In conclusion, whole blood values by most of the SMBG instruments are well correlated with plasma automated values, although some disagreement was noted. Values at forearm are not different from plasma val ues of antecubital vein, while at finger tip SMBG values showed higher levels. The measurement at forearm is therefore recommended, and in addition the pain is less.

According to increment of detection of the "small" size peripheral lung cancer measuring less than 20 mm in the greatest dimension, the "less" invasive VATS lobectomy has became widespread among the general thoracic surgeon. To decide on the indication of VATS lobectomy, the frequency of nodal metastasis and recurrence were examined in relation to size of the tumor. The diagnostic accuracy of nodal status in clinical and pathological examinations was 88% in the group with tumors less than 20 mm, 79% in the 21 to 30 mm group and 63% in the c-T2 group, respectively. Also, recurrencies were experienced more frequently in c-T2 (44%) than in c-T1 (19%). In our department, the VATS lobectomy was introduced under the condition as follows; the clinical stage should be limited to T1N0M0. Intraoperative histological examination of the locoregional lymph nodes is required to avoid the risk of local recurrence. In these limited conditions, the survival rate of VATS lobectomy is slightly superior to that of the standard thoracotomy in a same clinical stage. In the future, the application of this procedure should be investigated in older patients, and in more advanced cases.

We examined the clinical effect of sulbactam/cefoperazone (SBT/CPZ) on respiratory tract infections in elderly patients (from 65 to 91, average 70.8) with underlying respiratory diseases. Thirty (30) patients (25 men and 5 women) were registered and SBT/CPZ (2 g/day) divided into two doses, was administered intravenously through drip infusion. The efficacy rate was 63% (excellent in 1 patient and good in 18 patients). No significant difference in efficacy was found among patient's age groups (group 1: 65-69, group 2: 70-74, group 3: 75-79, group 4: > 80). Bacterial eradication rate was 50% (6 out of 12 strains). An adverse reaction occurred in one patient, who experienced uticaria. Laboratory abnormalities, which were increasing with their ages, were observed in 12 patients during the study. These results suggest that SBT/CPZ was effective, but we found it is important to use caution in the treatment of elderly patients on respiratory tract infections with underlying respiratory diseases.

To evaluate the utility of photon counting X-ray radiography (quantum radiography: QR) for the detection of pulmonary nodules, experimental and clinical studies were performed in comparison with conventional X-ray (CXR). In the experimental study, spatial resolution was analyzed by using the micro-chart method. The simulated nodule detection study was performed by using a chest phantom. The results were evaluated by means of ROC analysis. In the clinical study, both images of CXR and QR were evaluated in a case of metastatic lung tumor. In the experimental study, the spatial resolution of QR was 200 microns. QR was superior to CXR in detecting simulated nodules in all areas. In clinical cases, QR was superior to CXR in depicting not only normal structures but also retrocardiac and retrodiaphragmatic pulmonary nodules.

A case of primary chylopericardium in a 54 year-old-man was reported. Despite 3 times of pericardiocentesis, the pericardial fluid accumulated rapidly. After the fenestration of pericardium, a small cannula was inserted for the thoracic ductgram which showed a clearly visible duct upward to the angulus venosus and an abnormal branch near the bifurcation of the trachea spilling some contrast material into the pericardial cavity. Ligation and division of the thoracic duct including an abnormal branch was performed from its entry to the thorax for a length of 13 cm upward. The postoperative course was uneventful and chest X-ray film taken 6 months after surgery showed no accumulation of chyle in the pericardium and pleural cavity.

In order to evaluate relationship between circulating androgens levels and development of ovarian hyperstimulation syndrome (OHS) in anovulatory patients treated sequentially with hMG and hCG, serum concentrations of androstenedione (A), testosterone (T) as well as estradiol (Ed) were measured serially in a total of 17 anovulatory patients including 9 who did not develop OHS and 8 who developed mild or moderate OHS. Increase of Ed levels during the period of hMG treatment varied remarkably in individual patients with OHS ranging from 7.2 to 190.1 times as much the pretreatment value. On the other hand, increase of A levels during the hMG treatment was recorded in the range from 2.0 to 3.2 times as much the pretreatment value in 4 patients with mild OHS, and from 1.5 to 5.9 in 4 patients with moderate OHS. However, the ratio of A increase remained within 1.4 times in patients without OHS. A transient increase of circulating T was observed in 2 days after commencement of hCG treatment, ranging between 1.4 and 3.2 times in patients without OHS, between 1.8 and 2.4 times in patients with mild OHS and between 3.8 and 6.8 times in patients with moderate OHS. It is concluded that serial measurements of A and T during the course of hMG and hCG treatments respectively appear to be an additional index other than Ed to predict development of OHS.
