[Preliminary clinical results of surgery for type A acute aortic dissections using gelatin-resorcin-formaldehyde glue].
We used gelatin-resorcin-form-aldehyde (GRF) glue to fuse the false lumen of type A acute aortic dissection in four patients. All were operated on within 3-24 hours after onset, and gluing of the two cylinders of the dissecting aorta could be done safely in a short time. Initial intimal tears were located in the transverse aorta in three patients and in the proximal descending aorta in one. Simple transection and end-to-end anastomosis of the ascending aorta was done for the first two cases. But in the last two patients, we resected the intimal tear in the transverse aorta and applied GRF glue to the stump of the aortic arch and to that of the aortic root, followed by graft replacement of the ascending aorta. There were no hospital deaths. But we had to reoperate on one patient five months after the first operation due to potentially residual dissection in the aortic root. GRF glue is a very useful adhesive for acute aortic dissection operations, but further refinement of the operative technique using it is necessary.

[A case of completely responding stage D2 prostatic cancer with no evidence of disease 14 years after diagnosis].
A 58-year-old male complaining of pollakisuria, miction pain and back pain visited us Dec. 26, 1979. Rectal examination revealed the prostate enlarged by 5 digital width, stony hard and irregular. Transrectal needle biopsy revealed moderately differentiated adenocarcinoma of the prostate. Bladder neck invasion, pelvic and mediastinal lymph node metastases and multiple bone metastases were found. The case was diagnosed with prostatic adenocarcinoma T3N2M1 (OSS, LYM) stage D2. Three courses of chemotherapy using ifosfamide applied from Feb. 2, 1980 showed no marked effect except for partial pain relief. Hormonal treatment with diethylstilbestrol diphosphate was started from May 28 and arterial infusion chemotherapy using CDDP and 5-FU was performed 2 months later, resulting in size reduction of the prostate and pelvic lymph node metastases and disappearance of mediastinal lymph node metastases. Needle biopsy of the prostate was negative for cancer cells. After 8 months, Tegafur was started, and 12 months later radiotherapy was added to the prostate and pelvic lymph nodes. The abnormal accumulation in bone scan began to decrease after 14 months and achieved complete remission 28 months after the initial therapy. We discontinued the hormonal therapy 31 months later because of his complaint of chest discomfort and palpitation. At the present time, 14 years after the initial therapy, the prostate was 35 x 29 x 19 mm in size on transrectal ultrasonography with undetectable serum PSA level and no tumor cells but only mass fibrosis has been seen by pathological examinations. We considered this patient to be with no evidence of disease.

Mediastinal lymph node metastasis 38 months after surveillance for stage I seminoma: a case report.
We present a case report of a relapse to the mediastinal lymph node alone, 38 months after orchiectomy on surveillance for stage I typical seminoma. The patient, a 63-year-old man, was treated with high inguinal orchiectomy for left testicular tumor and close follow-up. After 38 months from the initial treatment, the chest X-ray film and CT scan revealed mediastinal tumor. Fine needle aspiration cytology performed under the bronchoscopy showed seminoma cells. Complete remission was achieved after three courses chemotherapy of cisplatin, vincristine, methotrexate, peplomycin and etoposide (COMPE). He has continued to be clinically disease-free 8 months after completion of the treatment. According to the available data in the literature, 94% of the recurrences was detected within 3 years after orchiectomy, and 92% involved retroperitoneal lymph node metastases. This is a rare case who had a late relapse in the mediastinum alone.

[Management of voiding dysfunction in elderly patients: effectiveness of rehabilitation and familial care].
We examined whether the improvement of impaired mobility correlates with the success rate in achievement of catheter-free or diaper-free status of 260 hospitalized elderly patients whose activities in daily life (ADL) were impaired and urinary tract dysfunctions including urinary incontinence were managed by indwelling catheters or diapers. The contribution of physical rehabilitation and/or care given by family to the improvement of impaired mobility was also investigated. All 154 patients whose ADL improved during the course of the treatment acquired the catheter-free or diaper-free status. Of 106 patients whose ADL did not improve, 85 patients became free of catheters or diapers. All of the remaining 19 patients who continued to be dependent upon catheter or diapers had been bed-ridden during the course of the treatment. Among 201 patients who were bed-ridden before the treatment, the success rate in the improvement of impaired ADL in 84 patients who underwent physical rehabilitation and received care given by family, was 83%. The ADL improved in 71% of the 70 who received rehabilitation and 53% of 17 bed-ridden patients who received familial care. By contrast, only 2 out of 30 patients who received neither of them were free from the bed-ridden condition. The remaining 28 patients continued to be bed-ridden, and the 19 cases who were not free of indwelling catheters or diapers were a part of this population of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Management of voiding dysfunction in elderly patients: prognosis 1 year after discharge from hospital].
We investigated how 293 elderly patients who had been successfully treated to be free of catheters or diapers managed to urinate one year after their discharge from our hospital. Of 192 patients who returned to their own home 154 (80%) had good activities in daily life (ADL), and of 101 who moved to a nursing home or other hospital only 7 (7%) had good ADL. Among the 192 in their own home, 151 (79%) remained free of catheters or diapers thanks to the home care services provided by trained nurses belonging to our hospital. However, among the 101 at other facilities 21 (21%) could avoid these appliances. Furthermore, those who stayed in their own home with poor ADL had a significantly higher rate of being independent of catheters or diapers (34%) compared to those who lived in facilities other than their home with poor ADL (13%). These findings indicate that the elderly patients who reside in their own home or have good ADL possess a better chance of avoiding catheters or diapers compared to those who live in other than their residence or have poor ADL, and that continued urological care coupled with the home-visiting services is effective and important in attaining these aims.

[A case of successful surgical treatment for coarctation of the aorta associated with ruptured cerebral aneurysm].
We present a case of a sixteen year old boy with coarctation of the aorta who suffered ruptured cerebral aneurysm. Both cerebral and aortic lesions were successfully corrected. He complained of sudden headache and nausea. Subarachnoid hemorrhage was diagnosed by computed tomography of the head. Cerebroangiography demonstrated coarctation of the aorta. Clipping of cerebral aneurysm was done at first, then three months later, complete resection of the aortic coarctation and artificial graft replacement was done by using femoral veno-arterial cardiopulmonary bypass.

[A case of Rubinstein-Taybi syndrome with bilateral vesicoureteral reflux].
The case was in a 7-month-old boy. Rubinstein-Taybi syndrome was diagnosed from the broad halluces and the characteristic physiognomy noticed since birth. He was brought to us at 7 months of age with fever as the chief complaint. Voiding cystourethrogram showed bilateral vesicoureteral reflux. The testis was palpable in the inguinal canal on either side, but could not be brought to the scrotum. No abnormalities were detected in the penis. From the above findings, he was diagnosed to have bilateral 4th degree vesicoureteral reflux and undescended testes as complicating Rubinstein-Taybi syndrome. The condition was treated by bilateral anti-reflux repair and bilateral orchidopexy at 8 months of age. There has been no recurrence of vesicoureteral reflux for 3 years. A brief discussion was made about the urological complications of Rubinstein-Taybi syndrome.

[A case of thoracoscopic pulmonary lobectomy for lung cancer].
A case of thoracoscopic right lower pulmonary lobectomy is reported. A 79-year-old man was admitted to our hospital after the accidental finding of a right pulmonary growth. A computed tomography (CT) scan of the thorax confirmed the presence of a neoplasm, 2.5 cm in diameter, at the posterior-basal segment of the right lower lobe. Considering the general condition of the patient and the characteristics of the lesion, we decided to perform a assess the possibility of a thoracoscopic lobectomy instead of the traditional posterolateral approach. The pulmonary artery was dissected with the new endoscopic cherry dissector, and ligated with the polyester suture material and Endo Clip then dived with Endo scissors. The lower pulmonary vein was dissected with this endoscopic cherry dissector and divided with Endo GIA 30 clamping the new thoracoscopic De Bakey type vascular clamp. The specimen was extracted through the minimal thoracotomy (15 cm). The postoperative course was uneventful with minimal postoperative pain, and the patient was discharged after complete surgical recovery with excellent functional and cosmetic results.

[Clinical evaluation of sulbactam/cefoperazone for infections during the chemotherapy of hematologic malignancy].
In 28 patients with hematologic malignancy, the clinical effect and the safety of sulbactam/cefoperazone (SBT/CPZ) were studied on 45 episodes during granulocytopenic stage after antineoplastic chemotherapy. The overall efficacy rate obtained with SBT/CPZ in combination with other drugs was 62%. The rates for sepsis, suspected sepsis and pneumonia were 67%, 94% and 38%, respectively. The efficacy in those cases that showed granulocyte count less than 300/microliters during the course of administration of SBT/CPZ was 53%, and in those cases that showed granulocyte counts recovery to more than 300/microliters was 73%. Prior antimicrobiological treatments had no influence on the efficacy of SBT/CPZ. SBT/CPZ showed an activity spectrum covering frequently isolated microorganism including Acinetobacter calcoaceticus, Pseudomonas aeruginosa, Enterobacter cloacae and Staphylococcus aureus. Mild adverse effect were observed in 4 episodes (8.8%). These result suggested that SBT/CPZ was thought to be a useful drug for empirical therapy in granulocytopenic patients with hematologic malignancies.

[Surgical treatment of descending thoracic aortic aneurysm with simple aortic cross-clamping versus left heart bypass using centrifugal pump].
Surgical treatment has been employed in 52 patients (pts) with descending thoracic aortic aneurysm (DS-TAA). Based on the adjuncts during aneurysmal repair, the series is divided into 2 groups; simple aortic cross-clamping was utilized to manage the lesion in group SC (n = 42), while left heart bypass using a centrifugal pump was employed during the period of aortic occlusion in LHB group (n = 10). Of these 52 pts, 4 died in hospital (group SC:2, group LHB:2). The most common complication was the respiratory failure following the renal failure. No paraplegia occurred in both groups. Biochemistric measurements of alanine aminotransferase, creatinine (CRN) and amylase (AMY) showed no difference between group SC and group LHB. In pts of SC group with normal renal function, post-operative maximum (post Max) CRN during the first month had a logarithmic correlation with total aortic cross-clamp time (TAXT). The post Max CRN of LHB group with normal renal function remained less than 3.0 mg/dl even in the case with TAXT over 60 minutes. There is also a linear correlation of post Max AMY in pts of SC group. Late survival at 4 years, including hospital death, were 83% in SC group and 63% in LHB group. We conclude that DS-TAA cases with TAXT of less than 30 min with good distal organ function can be managed with simple aortic cross-clamping; otherwise usage of LHB was recommended to support distal circulation.

Influence of psychological stress on suckling-induced pulsatile oxytocin release.
OBJECTIVE: To investigate the influence of psychological stress on suckling-induced oxytocin release. METHODS: The pulsatile release of suckling-induced oxytocin was measured in 22 puerperal women. The blood samples for oxytocin assay were collected at 2-minute intervals in a manner that minimized degradation by plasma oxytocinase, and were used for radioimmunoassay after extraction. RESULTS: The release of suckling-induced oxytocin during nursing is pulsatile, with discrete, short pulses. The frequency of pulsatile release of oxytocin was significantly lower in the two groups in which stress was imposed by mental calculation or noise than in the control group without stress (mental calculation group, 1.28 +/- 0.76 pulses/20-minute suckling period; noise group, 1.14 +/- 0.38; control group, 2.25 +/- 0.71). However, there were no differences among the three groups in the increase of prolactin during nursing or in the milk yield. CONCLUSIONS: The release of suckling-induced oxytocin is pulsatile, and psychological stress reduces the pulsatile oxytocin release. Our data suggest that suckling-induced oxytocin release may be modulated by the central nervous system and that psychological relaxation is necessary for an adequate let-down response.

[Caregiving burden of elderly caregivers who provide at home care for infirm elderly].
In order to elucidate the degree of feeling burdened and factors affecting caregiving burden of elderly caregivers, a questionnaire survey was performed on 241 female caregivers of infirm elderly. The surveyed group consisted of 138 caregivers under 60 years of age (young group) and 103 aged 60 and over (old group). The major results of this survey were as follows, 1) Conditions perceived as unfavorable in the old group were related to caregiving assistants, number of the family members and health condition of the caregiver. 2) Greater number of infirm elderly with serious ADL problems and higher average body weight of the elderly cared for were seen for the old group than the young group. 3) The old group had a larger number of problem incidents and expressed more eager desire for transfer of elderly to institutional care than providing the young group. 4) A feeling of burden in daily care appeared larger for night care, body discharge disposal and bathing care of the elderly and was more frequent in those above 70 than under 70 years of age. 5) Hours in bed were longer and range of movement by wheel chair was more limited for infirm elderly as the caregiver's age increased. These results suggest that the above-mentioned unfavorable conditions in elderly caregivers promote a state of becoming bedridden and a lowering of ADL ability of infirm elderly.

[Treatment with arbekacin of surgical infections by resistant strains of Staphylococcus aureus. Arbekacin Study Group].
The frequency of infection by methicillin-resistant Staphylococcus aureus (MRSA) is high in Japan and control of such strains is urgently needed. Arbekacin (ABK), a semisynthetic aminoglycoside, has potent activity against S. aureus, including resistant strains, and against Gram-negative bacteria as well. For this reason, in surgical infections (which are often caused by more than one bacterium), this drug might be particularly effective. We calculated the MIC and the decrease in the MIC when cultures of 59 resistant strains of S. aureus isolated in our wards at Osaka City University Hospital, contained arbekacin in the medium. We also used the drug to treat 12 infections caused by resistant strains of S. aureus. The MICs of vancomycin had a single peak at 0.5 microgram/ml, and those for ABK had double peaks at 0.5 and 4.0 micrograms/ml. The effect of arbekacin in lowering the MIC of minocycline (MINO) was slight because of the low MIC of MINO. Effects on fosfomycin (FOM), ampicillin, clavulanic acid/ticarcillin, cefotiam, cefuzonam, flomoxef, and imipenem/cilastatin were strong; the peaks were lowered by 1/2(7)-1/2(11). When 1.0 micrograms/ml ABK was present in the medium, the efficacy of FOM was increased enough that, by prediction from the pharmacokinetics of FOM (blood level when given at the usual dose), all but one (2%) of the 47 resistant strains would be eradicated clinically. If 2.0 micrograms/ml ABK were in the medium, all strain would be eradicated, by our calculations. We treated 11 infections and one colonization by resistant strains of S. aureus with ABK and evaluated the response in these cases of infection. Four infections were treated with FOM as well. The clinical efficacy was good in four infections (three patients), fair in four, and poor in three, for an efficacy rate of 36%. All presumed causative bacteria were eradicated in two (18%) of the 11 infections and S. aureus strains were eradicated in three (27%) of the 11 infections. No symptoms of side effects were reported, but blood urea nitrogen and creatinine rose in a 72-year-old woman with duodenal perforation and peritonitis. The MIC levels of ABK were satisfactory, but clinical efficacy for staphylococcal infections caused by resistant strains was unsatisfactory.

[A case of subacute stroke with high uptake of 99mTc-HMPAO in the reperfused infarct corresponding to low perfusion area].
We reported a case of subacute stroke which showed high uptake of 99mTc-d,l-hexamethylpropyleneamine oxime (HMPAO) in the reperfused infarct corresponding to slightly decreased perfusion by 133Xe inhalation CBF measurement. In the chronic stage, both SPECT images of 99mTc-HMPAO and 133Xe showed low perfusion in the affected lesion. It was, therefore, considered that the high uptake of 99mTc-HMPAO had represented luxury perfusion. In the subacute stage of stroke, high uptake of 99mTc-HMPAO may imply luxury perfusion but not always hyperperfusion. It is suggested that the fractional fixation of 99mTc-HMPAO temporarily change in the affected lesion and it is essential to take into consideration the clinical stage for the interpretation of SPECT images.

Cerebral blood flow study in patients with moyamoya disease evaluated by IMP SPECT.
UNLABELLED: We studied the usefulness of IMP SPECT with acetazolamide in 16 patients with moyamoya disease. Cerebral angiography was performed for all patients who were classified in three grades according to their angiographic stages. METHODS: Techniques used included ring-type emission computed tomography with a minicomputer system. Patients received 111 MBq of 123I-IMP and SPECT images were obtained 20 min postinjection. Nine patients were studied using iodoamphetamine (IMP) SPECT with and without acetazolamide. IMP SPECT with acetazolamide was performed 20 min after each injection of 1 g of acetazolamide. RESULTS: Low perfusion areas in the upper and lower frontal, parietal and temporal regions in grades 2 and 3 using IMP SPECT were observed. The mean cerebral-to-cerebellar activity ratios (C/C ratio) of six regions (upper and lower frontal, temporal, parietal occipital and basal ganglia) in grades 1, 2 and 3 were 0.96 to 1.06, 0.91 to 0.96 and 0.76 to 0.88, respectively. CONCLUSION: Our results indicate that measurement of regional cerebral blood flow (rCBF) elucidates cerebral hemodynamic factors, including the reactivity of cerebral vessels which cannot be detected angiographically in patients with moyamoya disease, and that the acetazolamide test is useful for detecting cerebral blood flow reserve. The test can be used to detect disease progress prospectively.

Measurement of portal systemic shunting by oral and per-rectal administration of [123I]iodoamphetamine, and clinical use of the results.
UNLABELLED: OBJECTIVE. We used a method by which the portal shunt index via the superior mesenteric vein (SI-S) and that via the inferior mesenteric vein (SI-I) could be evaluated simultaneously. The clinical usefulness of the method was studied. METHODS: Scintigraphy was done 3 h after subjects took an enteric-coated capsule containing [123I]iodoamphetamine. At that time, the radionuclide was injected into the rectum. Counts for the lungs and the liver were used to calculate the two shunt indices. RESULTS: The mean SI-S and SI-I tended to be higher for disorders that were more severe, increasing in the order of chronic persistent hepatitis, chronic aggressive hepatitis, and cirrhosis. In cirrhotic patients, the SI-I was higher than the SI-S (p < 0.001). The SI-S and SI-I were both higher in cirrhotic patients with esophageal varices than in such patients without varices (p < 0.05 and < 0.001). The SI-S and SI-I were higher in cirrhotic patients with ascites than in such patients without ascites (p < 0.001 and < 0.01). Correlation between either of these indices and classical indicators of functional reserve was high. The correlation of SI-S with the Child-Turcotte classification and total bilirubin level was higher than the correlation of the SI-I and these indicators of functional reserve. CONCLUSIONS: This method permits assessment of the portal hemodynamics in a relatively noninvasive way, and is clinically meaningful.
