TOSHITATSU NOGITA M.D. NAOKO MORIOKA M.D. YASUMASA ISHIBASHI M.D. MAKOTO KAWASHIMA M.D. MASAKO MIZOGUCHI M.D. FUJIO OTSUKA M.D. 《International journal of dermatology》1992,31(12):864-865
Neutrophilic dermatoses (ND), with or without accompanying myelodysplastic syndrome (MDS), were examined in terms of nuclear abnormality like pelgeroid anomaly of infiltrating cells into skin lesions. Six ND accompanying MDS showed 1.0 to 13.5% of such anomalous cells among infiltrating cells. In contrast, ND without accompanying myeloproliferative disorders rarely had such anomalous cells. Our findings suggest that pelgeroid-like anomalous cells infiltrating into ND are probably a good marker of underlying MDS. 相似文献

BACKGROUND: The value of serum prostate-specific antigen (PSA) screening was examined to detect prostate cancer in men receiving hemodialysis. METHODS: Forty-one male patients age 60-95 (median age, 70 years) receiving hemodialysis were investigated for PSA levels. We set the cut-off point at 4 ng/mL (the usual reference range). Digital rectal examination (DRE) and transrectal ultrasonography (TRUS) of the prostate were performed in patients whose PSA was more than 4 ng/mL and/or who expected further examination of the prostate. When prostate cancer was suspected, biopsy of the prostate was performed. In patients with prostate cancer, magnetic resonance imaging, computed tomography and bone scintigraphy were performed to diagnose the clinical stage. RESULTS: The mean serum level of PSA was 2.10 +/- 0.49 ng/mL. In this screening study, four of 41 men required further examinations for prostate cancer. Two of four refused further examinations. The other two were diagnosed with prostate cancer. The incidence of prostate cancer was at least 5% in our hemodialysis patients. One man, whose clinical stage was T2aN0M0, was treated with radical retropubic prostatectomy. Another man, whose clinical stage was T2bN0M0, was treated with luteinizing hormone-releasing hormone analogue. CONCLUSION: In our preliminary study, prostate cancer screening with PSA was useful for the early detection of prostate cancer in hemodialysis patients. If possible, DRE and TRUS should be performed in conjunction with PSA tests. 相似文献

Our objective was to determint; the adequate pacing rate during exercise in ventricular pacing by measuring exercise capacity, cardiac output, and sinus node activity. Eighteen patients with complete AV block and an implanted pacemaker underwent cardiopulmonary exercise tests under three randomized pacing rates: fixed rate pacing (VVJ) at 60 beats/min and ventricular rate-responsive pacing (VVIR) programmed to attain a heart rate of about 110 beats/min ar 130 beats/min (VVIR 110 and VVIR 130, respectively) at the end of exercise. Compared with VVI and VVIR 130, VVIR 110 was associated with an increased peak oxygen uptake(VVIR 110:20.3 ± 4.5 vs VVI: 16.9 ± 3.1; P < 0.01; and VVIR 130: 19.0 ± 4.1 mL/min per kg, respectively; P < 0.05) and a higher oxygen uptake at anaerobic threshold (15.3 ± 2.7, 12.7 ± 1.9; P < 0.01, and 14.6 ± 2.6 mL/min per kg; P < 0.05). The atrial rate during exercise expressed as a percentage of the expected maximal heart rate was lower in VVIR 110 than in VVI or VVIR 130 (VVIR 110: 75.9%± 14.6% vs VVI: 90.6%± 12.8%; P < 0.01; VVIR 110 vs VVIR 130: 89.1%± 23.1%; P < 0.05). There was no significant difference in cardiac output at peak exercise between VVIR 110 and VVIR 130. We conclude that a pacing rate for submaximal exercise of 110 beats/min may be preferable to that of 130 beats/min in respect to exercise capacity and sympathetic nerve activity. 相似文献

Summary We report a patient with primary lymphocutaneous Nocardia brasiliensis infection affecting the face and left arm. The mode of infection was via skin abrasions which occurred 2 weeks prior to the development of the skin lesions. Treatment with intravenous minocycline for 4 weeks resulted in a cure. We also review 12 previously reported Japanese cases of lymphocutaneous nocardiosis. 相似文献

Abstract: We studied 12 patients using endoscopic injection sclerotherapy (EIS) guided by endoscopic color Doppler ultrasonography (ECDUS). The ECDUS was performed with a PENTAX FG-32UA (7.5MH2, convex type) and a HlTACHl EUB 565 as a display machine. The EIS needle, as well as changes in intramural blood flow before and after EIS were clearly observed with the ECDUS. When the sclerosant was injected properly into the esophageal varices, the blood flow in the esophageal varices could not be detected with color Doppler flow imaging nor with fast-Fourier transform (FFT) analysis. Therefore EIS was safely performed with an adequate volume of sclerosant having been accurately injected into the varices. Of the disadvantages of this technique, the forceps channel was found to be a bit narrow, and the anterior view was somewhat oblique. Even so, EIS guided by ECDUS is surely a promising method for the treatment of esophageal varices, especially once the technical difficulties are overcome. (Dig Endosc 1994; 6 : 39–44) 相似文献

Abstract: We studied 14 patients using endoscopic color Doppler ultrasonography (ECDUS) to evaluate the hemodynamics of gastric varices, and evaluated the endoscopic therapeutic effects on gastric varices in 8 patients. Three patients had F3 type gastric varices and eleven had F2. The ECDUS was performed with a PENTAX FG-32UA (7.5MHz, convex type) and a HITACHI EUB 565 was used as a display machine. The intramural blood flow in the gastric varices and inflows from the extra-gastric wall were clearly observed with the ECDUS in all 14 patients. The extramural blood flow (gastro or spleno-renal shunts) was detected in 9 of 14 patients. The velocity of the intramural flow in tumorous type varices (F3) was higher than in the nodular or flat elevated type (Fa). Next, we evaluated the therapeutic effects on gastric varices of the ECDUS. The successful disappearance of intramural blood flow was observed in 6 of 8 patients who had this endoscopic therapy. In two of the 8 patients, there was not enough therapeutic effect on the intramural blood flow. The extramural blood flow, however, did not change before or after endoscopic therapy with the ECDUS. Therefore, we concluded that ECDUS is a very useful modality for the diagnosis of hemodynamics and to evaluate the therapeutic effects on gastric varices. 相似文献

Although the prime importance in treatment of head and neckcancer is eradication of tumors, due attention should be paidto the conservation of many important structures and functionsin the region. Just to mention a few of these important humanfunctions, there are phonation, digestion and facial expression.Simple surgical procedures specialized by otolaryngologistsare no longer satisfactory. Recently, radiotherapy of head and neck cancer has developedto a superlative degree and chemotherapy to a practical degreealthough much still remains to be satisfied. Our aim was toorganize an interdisciplinary group of specialists in surgery,radiotherapy and regional chemotherapy into a composite attackforce. We aimed at most effective treatment with the least ofside effects. Since 1961, our combined approach to cancer of the head andneck in close collaboration with radiotherapists has yieldedmuch improved results. This has led to an increasing numberof patients with satisfactory rehabilitation.
- 1. Cancer of the maxilla: Even in the advanced cases combinedsurgery, radiotherapy and regional chemotherapy has led to thepreservation of important structures and functions. Many patientsare now allowed to return to social life and to their previousjobs.
- 2. Cancer of the nasopharynx: Radiotherapy is the firstchoice.When the effect is less satisfactory, chemotherapy anda window-operationof the palate are performed.
- 3. Tumorsof the tonsils: The majority of patients suffer fromthe reticulumcell sarcoma. Radiotherapy is the first choice.
- 4. Cancerof the larynx: A full dose of radiotherapy is thefirst choice.Partial resections are done when indicated.
- 5. Cancer of thetongue, hypopharynx and esophagus: Radiotherapyis the firstchoice in the majority of cases. Some need plasticsurgery.

Serum dopamineβ-hydroxylase activity, which is thought to reflect noradrenaline secretion, and free fatty acid level were measured in twenty atopic asthmatic children, of whom ten had exercise-induced asthma (EIA), after exercise on the treadmill. There was a significant decrease in the level of serum dopamine β-hydroxylase activity in the asthmatics who developed EIA and this closely accompanied the onset of airflow obstruction. There was no change in the free fatty acid levels. In contrast, the asthmatics, who did not have EIA showed a significant rise in the levels of dopamine β-hydroxylase activity and free fatty acids after the same exercise task. Our results suggest that the atopic children studied, who developed EIA, may have had an impaired noradrenaline response to exercise. It is further suggested that this impaired noradrenaline secretion may facilitate mediator release and contribute to the airflow obstruction in EIA. 相似文献

This case of hepatocellular carcinoma (HCC) with alcoholic liver fibrosis, which was not associated with hepatitis viruses, was accompanied by hypoglycaemia. The immunoreactive insulin level was low and other hormonal examinations were almost normal. Immunohistochemical studies showed a high level of insulin-like growth factor II (IGF2) peptide in the HCC section and the size heterogeneity of serum IGF2 investigated by western blot revealed a large form at approximately 15 kDa. These results suggest that the HCC with alcoholic liver fibrosis produced IGF2 and that the hypoglycaemia was caused by tumour-associated IGF2. 相似文献
