Severe hypertension developed in a fifty-five year-old woman after surgical removal of a retroperitoneal tumor, when the renal artery was injured. Renal arteriography after the surgery demonstrated a segmental infarction of the right kidney. A close relationship between activation of the renin-angiotensin system and the development of severe hypertension was observed. Satisfactory control of blood pressure concomitant with reduction of plasma renin activity was achieved by a combination of an angiotensin-converting anzyme inhibitor, beta-blocking agent, and calcium-entry blocker. The mechanism of activation of the renin-angiotensin system in renal infarction is discussed. 相似文献

A man suffering from severe intermittent claudication of the right calf and foot was successfully treated by femoro-tibio-peroneal trunk autogenous vein bypass with adjunctive arteriovenous fistula. Prior to operation, he was unable to walk more than 50 meters without resting. Preoperative arteriography revealed extensive occlusion of the popliteotibial arteries, except for indistinct visualization of the tibio-peroneal trunk, in which conventional reconstructive surgery seemed not to be feasible because of poor distal run-off. An autogenous vein bypass graft between the distal superficial femoral artery and tibio-peroneal trunk was successfully made "in-situ", creating an adjunctive arteriovenous fistula. Postoperatively, the ankle pressure index of the posterior tibial artery was considerably increased from 0 to 0.65, and Doppler flow wave could be recorded. The patient can now walk more than 1,500 meters without resting. 相似文献

We encountered eight rare cases of myonephropathic metabolic syndrome (MNMS) which developed as a complication of the femoral arterial cannulation (FAC) during cardiopulmonary bypass (CPB). Seven were boys ranging in age from 4–17 years, and all had undergone open heart surgery using CPB with a hemodilution technique. These eight corresponded to 1.9 per cent of the 420 patients treated with CPB before June, 1974. The pump priming fluid used was either Ringer’s lactate solution alone or that containing a small amount of colloidal solution. Duration of CPB ranged from 52 min to 2 hrs and 42 min, but the FAC period was more than 3 hrs in each case. Acute renal failure occurred in 3 and 2 required peritoneal dialysis. Severe respiratory insufficiency occurred in 2 and one died 3 months after the operation. The most effective means to prevent the development of MNMS seems to be the local cooling of the cannulated limb during FAC. MNMS did not occur in 444 cases of CPB with FAC after July 1974, and here local cooling was applied in all cases. 相似文献

In 1998, we developed a Total Infection Control System in Saga Medical School Hospital, and would like to introduce it for the practical use. This system was named "Dr. FLEMING" (Flexible Microbiological Test & Information System for the New Generation) and is expected to help physicians by providing highly valuable test results and useful information. For example, bacterial identification and drug susceptibility test can be completed within 4-6 hrs after bacterial colony is isolated, and the test report the contains full-colored pictures to enhance understanding. In addition, we have made an information center for infectious disease, where physicians can have access to various data bases outside our hospital. Furthermore, we offer many kinds of useful information to physicians working at other medical facilities to assist their clinical practice of infectious diseases. 相似文献

A 68-year-old man was diagnosed as having bronchial asthma in November 1996. He presented with leukocytosis in June 2002. The WBC count was 29,900/microliter with 82% mature neutrophils showing toxic granules. The neutrophil alkaline phosphatase score and serum level of vitamin B12 were elevated. Bone marrow demonstrated myeloid hyperplasia and plasmacytosis. Cytogenetic and molecular analyses were negative for Philadelphia chromosome and BCR/ABL fusion gene. Lambda-type Bence-Jones protein was detected on the serum and urinary immunoelectrophoresis. The coexistence of chronic neutrophilic leukemia and myeloma was suspected based on the clinical features. The serum level of granulocyte-colony stimulating factor (G-CSF) was elevated. Immunohistochemically, atypical plasma cells were positive for anti G-CSF antibody. Finally, we diagnosed this patient as having a G-CSF-producing myeloma. Treatment with melphalan and prednisolone was initiated without beneficial response. He was then admitted to our hospital for ROAD therapy (ranimustine, vincristine, melphalan, and dexamethasone). The neutrophil count decreased in parallel with the serum G-CSF level. These observations indicated that the neutrophilia in this case was probably caused by a reactive response to G-CSF secreted from the myeloma cells. 相似文献

BACKGROUND/AIMS: Conflicting results have been reported concerning the usefulness of radiotherapy for unresectable pancreatic cancer. We evaluated the clinical efficacy of intraoperative radiotherapy and/or external beam radiotherapy in combination with bypass surgery. METHODOLOGY: Twenty-six patients with unresectable pancreatic cancer (16 in Stage II-III and 10 in Stage IV) were treated with intraoperative radiotherapy plus external beam radiotherapy (16 patients) or intraoperative radiotherapy alone (10 patients). The dose of intraoperative radiotherapy was either 25 or 30 Gy and the external beam radiotherapy dose was 31-60 Gy. The feasibility and clinical outcome were analyzed. RESULTS: The median survival time for Stage II-III and Stage IV were 11.5 and 6.5 months, respectively. The difference between Stage II-III and Stage IV in survival patterns was statistically significant (P < 0.05). For Stage II-III patients, the survival curves between the groups of intraoperative radiotherapy plus external beam radiotherapy and intraoperative radiotherapy alone were not significantly different, and only performance status was a significant factor in the prognosis (P < 0.05). Gastrointestinal bleeding was noted in 8%, but did not occur in the patients treated with an external beam radiotherapy dose less than 50 Gy. Palliative radiation was successfully performed to relieve pain, jaundice and appetite-loss and to shorten the hospital stay. CONCLUSIONS: The combination therapy with intraoperative radiotherapy and bypass surgery is considered to be tolerable and effective for unresectable pancreatic cancer, and also may improve the quality of life of the patients. 相似文献

A 33-year-old woman with a fever, cough, and pharyngitis was admitted after left-sided pleural effusion was detected. The fever and upper respiratory symptoms were confirmed, and she was diagnosed with coronavirus disease (COVID-19) after showing a positive polymerase chain reaction (PCR) test. After thoracentesis, pleural fluid revealed elevated adenosine deaminase values and a positive QuantiFeron test; tuberculous pleurisy was thus suspected. Subsequent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PCR and anti-SARS-CoV-2 Spike IgG tests were negative, suggesting that the initial PCR result had been erroneous. However, we were unable to confirm this. Data concerning COVID-19 diagnostics are insufficient at present. It is important to make comprehensive judgments regarding the diagnosis and treatment of patients as well as public health. 相似文献

A Phase I clinical trial of an anticancer agent is the first evaluation in humans, and it is an important step in drug development. From the ethical point of view, the goal is to escalate to the maximum tolerated dose quickly, yet safely, to minimize the likelihood of treating patients at doses that are too low or high. It is expected that the contradictions between safety and efficacy in the Phase I clinical trials will be solved by developing methods. The modified Fibonacci sequence has been generally adopted for dose escalation, although it includes some problems. It is necessary to recognize that the method used for Phase I clinical trials for anticancer agents remains unsatisfactory, and that it is also necessary to develop more ethical and scientific methods. 相似文献
