For the study of the relationship of the pelviureteric system of one kidney to that of the contralateral one, bilateral cutaneous ureterostomy was performed in 14 dogs. The renal pelvis (RP) and ureter (U) of one side were distended separately with a balloon filled with saline in increments of 1 and 0.25 ml, respectively, and the pressure response of the contralateral RP and U was recorded. The test was repeated after anesthetization of the RP and U. RP distension with 1 ml of saline effected a pressure rise (P < 0.05) in the ipsilateral RP but no pressure response in the ipsilateral U or the contralateral RP or U (P > 0.05). RP distension with 2, 3, and 4 ml of saline induced a significant pressure rise in the ipsi- and contralateral RP but not in the ureters. Ureteric distension produced a pressure elevation (P < 0.05) on the ipsilateral U but had no effect on the contralateral U (P > 0.05) or on either of the renal pelves (P > 0.05). Distension of the anesthetized RP or U effected no pressure response in any of the ipsi- or contralateral RPs or Us. In conclusion, distension of the RP with large volumes led to an increase in pressure in the contralateral RP but not in the U. A reflex relationship is postulated to exist between the two renal pelves and to be mediated through a reflex we call the reno-renal pelvic reflex. It seems that this reflex acts to allow either of the kidneys to share an extra load of the other one by increasing the contractile activity of the RP, thus assumedly assisting the regulation of urine flow.  相似文献

The authors evaluate the contribution of proteolytic enzymes used in the treatment of the lymphatic oedema of the arm after mastectomy and radiotherapy for breast cancer. Proteolytic enzymes were successfully administered in monotherapy of lymphatic oedema as well as supportive therapy in other therapeutically ways.  相似文献

Lymphoedema of the upper limb after breast cancer treated with axillary clearance is a well known sequels. But its real rate is not precise. The retrospective study of 683 patients approaches this reality. When clinic criteria are selected with centimetric measures, its general rate is 41%; 65% out of them have a difference smaller than 3 cm. We noticed three different kinds of lymphoedemas which occur on the arm, the forearm or the complete upper limb. Their volumes are different, the more voluminous ones occur when the upper limb is touched completely (P = 0.0001). The different factors which increase the risk of lymphoedema are described. The role of the infection is noticed (x 1.7). The rate is independent of the surgery, of the importance of axillary clearance and of the shoulder joint function. The lymphoedema size is more important when it occurs secondary to mastectomy then conservative treatment (P = 0.0078). Parietal fibrosis increases lymphoedema risk to 54% (P = 0.005) and lymphoedemas are more voluminous (P = 0.009).  相似文献

PURPOSE: To evaluate the safety and efficacy of breast-conserving therapy for young women with a family history (FH) suggestive of inherited breast cancer susceptibility. MATERIALS AND METHODS: A total of 201 patients aged 36 or younger at diagnosis treated with breast-conserving surgery and radiation therapy (> or = 60 Gy) for early-stage breast cancer were categorized by FH. FH was considered positive in 29 patients who, at the time of diagnosis, had a mother or sister previously diagnosed with breast cancer before age 50 or ovarian cancer at any age. Clinical, pathologic, and demographic variables; sites of first failure; disease-free survival; and overall survival (OS) were compared between FH-positive and -negative groups. Median follow-up time was 11 years. RESULTS: Patient and tumor features were similar between those with and without an FH. Regression analysis of sites of first failure at 5 years demonstrated a risk ratio (RR) of 5.7 for opposite breast cancer for FH-positive patients. Rates of local, regional, and distant failure and disease-free survival or OS did not differ between FH-positive and -negative patients. Age at diagnosis and Ashkenazi heritage were not significantly predictors of patterns of failure. CONCLUSION: Breast-conserving surgery combined with radiation therapy is not associated with a higher rate of local recurrence, distant failure, or second (non-breast) cancers in young women with an FH suggestive of inherited breast cancer susceptibility compared with young women without an FH. However, their increased risk of opposite breast cancer should be taken into account when considering breast conservation as a treatment option.  相似文献

A proteinase accumulated in breast secretions from women with breast cancer has been characterised. Inhibition of the proteolytic activity of breast secretions by pepstatin A showed that the main enzyme involved was an aspartyl proteinase. Determination of its cleavage specificity by SDS-PAGE and amino acid sequence analysis revealed that it was identical to that of cathepsin D, an aspartyl proteinase suggested to be involved in breast cancer development. The identity between both proteins was further confirmed by immunological analysis with monoclonal antibodies against cathepsin D. Quantification of cathepsin D in nipple fluids from 41 women with benign or malignant breast diseases and from 19 control women without breast pathology revealed the presence of variable amounts of this proteinase. The average concentration of cathepsin D in breast secretions from cancer-bearing breasts was 7.2 +/- 2.2 fmol micrograms of protein, which was significantly higher than those of nipple fluids from control women (2.9 +/- 0.6 fmol micrograms-1) (P = 0.04) or from patients with benign breast diseases (2.1 +/- 0.3 fmol micrograms-1) (P = 0.004). Though the number of cancer patients studied was small (n = 21), no correlations were found with cytosolic concentrations of cathepsin D or oestrogen receptors, neither with other parameters such as tumour size, histological grade, axillary node involvement or menopausal status.  相似文献

Approximately 25% of breast cancers occur in premenopausal women. In addition to local therapy, surgery or surgery plus irradiation, systemic chemotherapy administration has become the standard of care for all node-positive and many node-negative patients. Systemic adjuvant chemotherapy can result in ovarian dysfunction or failure. This renders many women prematurely estrogen deficient. The consequences of menopause, genitourinary atrophy, bone loss, and increased risk of cardiovascular disease, have not been routinely assessed in clinical trials. The risks of estrogen deficiency have not been assessed in comparison to improved disease-free and overall survival benefits of adjuvantly treated premenopausal breast cancer patients. Estrogen-replacement therapy in postmenopausal women has been shown to prevent osteoporosis and reduce fracture risk. The majority of studies also show a marked reduction in cardiovascular disease and mortality. Estrogen-replacement therapy has been considered a disease-prevention strategy rather than a therapeutic intervention. The risks and benefits of estrogen-replacement therapy in women with primary breast cancer are unknown. It is unknown how the well-known benefits accrued from reduction in skeletal and cardiovascular morbidity/mortality compare with the potential risks of increased breast cancer morbidity/mortality. Carefully designed prospective clinical trials with well-defined objectives and endpoints are required to learn if more harm than good is done by the withholding of estrogen therapy in breast cancer patients.  相似文献

OBJECTIVE: To evaluate the accuracy of cytologic screening in pregnancy through routine colposcopy and to confirm the safety of conservative management of cervical intraepithelial neoplasia (CIN) in pregnancy. STUDY DESIGN: In total, 3,658 pregnant women, screened for cervical cancer with either cytology or colposcopy, were prospectively evaluated. Patients with abnormal findings underwent colposcopically directed biopsy and, in case of CIN, repeat cytology and colposcopy. Biopsy was repeated in case of suspected progression of the lesion. Suspected microinvasion was the only reason for diagnostic conization during pregnancy. After delivery, excisional treatment provided a final specimen from all patients. Diagnostic methods were compared. RESULTS: Comparison between cytology and colposcopy showed 97.1% concordance with a few false positives (2.5%) and false negatives (0.2%). Abnormal cytology and colposcopy, as compared with histology, showed similar concordances, but the risk of underestimation by cytology was significantly higher (P < .05). Initial and final histology of the 63 cases of CIN and microinvasive carcinoma showed 88.9% concordance. Progression of the lesion was not observed. CONCLUSION: These data do not justify combined use of cytology and colposcopy to improve screening for cervical cancer in pregnancy. Delayed treatment of CIN after delivery is safe.  相似文献

Oestrogen replacement therapy in women with a history of breast cancer has long been considered contraindicated. However, the literature does not indicate an increased risk of recurrent breast cancer in postmenopausal women receiving oestrogen replacement therapy. We advocate that women with a history of breast cancer without nodal involvement could be offered oestrogen replacement therapy and thereby benefit from prevention of cardiovascular disease and osteoporosis. But the patients must accept a potentially increased risk of recurrence. We emphasize the need for randomized prospective studies.  相似文献

The preferred therapy for genuine stress incontinence is surgery. The Burch procedure is considered by many to be the gold standard for surgical treatment of genuine stress incontinence. The Burch procedure requires the elevation of the anterior wall of the vagina to the level of the origin of the paravaginal fascia by suspension from Cooper's ligaments. The laparoscopic performance of the Burch procedure by suturing or by endoscopic stapler mesh technique results in a decrease in the length of hospital stay, faster recovery, much shorter catheterization and less scarring due to the smaller incisions. The laparoscopic procedure provides results similar to the open operation if a meticulous technique is used. Long-term follow-up will be necessary before these procedures can be generally offered as a therapeutic alternative.  相似文献

The necessity of screening high-risk patients with breast cancer who may require more intensive systemic therapy especially in the node negative subgroup was generally accepted. Cathepsin D, an estrogen induced protease, has been shown to be implicated in the proliferation and invasion of breast cancers. Retrospective assessment of cytosol cathepsin D in 151 primary breast cancers was done together with ER, PR and other clinico-pathological parameters. No significant relationship was shown between cathepsin D concentrations or cathepsin D status using median value of 56 pmol/mg protein as cutoff level with most studied parameters. High cathepsin D status was found in 47 per cent of patients with fibrocystic disease of breast and 30 per cent in node-negative, ER-PR negative tumors. Survival analysis after 5 or 10 year follow-up and evaluation in a larger scale are necessary before including cytosol cathepsin D measurement as a routine clinical investigation for breast cancers.  相似文献

Endocrine tumors, such as parathyroid adenomas and pheochromocytomas, frequently have deletions of chromosome 1, suggesting that inactivation of a tumor suppressor gene from chromosome 1 is important in their tumorigenesis. We hypothesized that deletion of chromosome 1 may contribute to pancreatic endocrine tumor formation. Twenty-nine sporadic and MEN1 pancreatic endocrine tumors were studied for loss of heterozygosity (LOH) with 12 chromosome 1 microsatellite markers. LOH on chromosome 1 was identified in 10 of 29 (34%) tumors studied. Allele loss occurred more frequently in tumors with hepatic metastases (7 of 8) than tumors without metastases (3 of 21) (P = 0.004). Tumors in patients with lymph node involvement and patients with multiple endocrine neoplasia type 1 did not demonstrate LOH for chromosome 1 markers. These data suggest that loss of chromosome 1 is associated specifically with the development of hepatic metastases in patients with sporadic pancreatic endocrine tumors.  相似文献

During the practice of every gynaecologist there have been women whose only complaint have been pelvic pain. In recent years the pelvic pain occupies one of the leading positions as an indication for laparoscopy. The author has carried out observations over 69 patients with such problems. The phlogistic changes of the adnexa have been the most frequent endoscopic finding, followed by the endometriosis. The other pathological changes in the small pelvis combined with pelvic pain have been the varicose changes in the vascular net of the ovaries, the mesosalpinx and the parameters. The author recommends laparoscopy for objectivization of the changes in the small pelvis and for determining the appropriate medical approach.  相似文献

Surgery alone does not cure breast cancer, and adjuvant chemotherapy has changed the management of this disease. Data obtained in 81 premenopausal women with operable breast cancer, treated at our clinic, are presented. Patients with axillary node disease were treated on three different protocols: cyclophosphamide + methotrexate + fluoro-uracil + vincristine + prednisone (CMFVP), cyclophosphamide + methotrexate + fluoro-uracil (CMF), and CMF + immunotherapy with methanol extract residue of BCG (CMF + MER). Patient discriminants and treatment regimens are discussed. Analysis of the results obtained in 49 patients in one study showed an extension of disease-free survival to 4,25 years, that CMFVP was superior to CMF with or without MER, and that immunotherapy was not beneficial. The literature is briefly reviewed and the motivation for our newer studies stated.  相似文献

Diagnosis of life-threatening illness now meets Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) criteria for traumatic stressor exposure for posttraumatic stress disorder (PTSD). Quality of life (QOL) and PTSD-like symptoms were assessed in 55 women posttreatment for breast cancer. PTSD symptom measures included the PTSD Checklist—Civilian Version (PCL-C) and the Impact of Events Scale. QOL was assessed using the 20-item Medical Outcomes Study Questionnaire. PTSD symptomatology was negatively related to QOL, income, and age. Time since treatment, type of cytotoxic treatment, and stage of disease were unrelated to PTSD symptoms. With suggested criteria for the PCL-C, 5% to 10% of the sample would likely meet DSM-IV PTSD criteria. Findings suggest that in survivors of breast cancer, these symptoms might be fairly common, may exceed the base rate of these symptoms in the general population, are associated with reports of poorer QOL, and, therefore, warrant further research and clinical attention.

Examination of sister-chromatid exchanges (SCE) in lymphocytes may be useful for the evaluation of exposure to mutagens/carcinogens. Information of a possible association between SCE and cancer is scarce. We therefore examined SCE in peripheral lymphocytes in 131 women, aged 17-90 years (median 51.8 years), coming to operation because of a tumor of the breast. Venous blood samples were cultivated during PHA stimulation in the presence of BrdU. After treatment with colcemid (R), fixation, treatment with bisbenzimide and staining with Giemsa, 30 metaphases were scored in each specimen. 52 patients with peroperatively demonstrated carcinoma of the breast had 9.39 +/- 0.17 SCE/cell and the remaining 79 women with non-malignant fibroadenomatosis had 9.88 +/- 0.18 SCE/cell. By multiple regression analysis it appeared that the character of the tumor, the patient's age, hormone treatment and preoperative examination by mammography all were without significant influence on the SCE rate. A statistically significant correlation was found between SCE and cigarette smoking. THe 45 cigarette-smoking patients had 10.49 +/- 0.23 SCE/cell compared with 9.26 +/- 0.13 SCE/cell in the 86 non-smokers. It was concluded that spontaneous SCE in lymphocytes is not an indicator of carcinoma of the breast.  相似文献

Although variously shaped urinary red cells have been reported in glomerulonephritic hematuria, no specific shapes with concrete definition have been proposed. This made morphological differentiation of hematuria vague and caused different results among different observers. To solve these problems and improve the diagnostic rate, we employed a uniquely shaped red cell, which only appeared in glomerulonephritic hematuria, as a probe for diagnosis. We studied 182 hematuria cases from 90 glomerulonephritic patients and 95 hematuria cases from 68 urological disease patients. Fresh urine was collected and observed by differential interference microscopy. The red cell, referred to as G1, has a distinctive doughnut-like shape with blebs and was highly specific for glomerulonephritic hematuria. Occurrence of G1 cells increased at lower pH an higher osmolality of urine. A presence of 5% or more G1 cells could be an indicator of glomerulonephritic hematuria. Specificity and sensitivity of this criterion were 100 and 73%. However, when only acidic concentrated urine (pH < or = 6.4, osmolality > or = 400 mosm/kg H2O) was used, the specificity and sensitivity increased to 100 and 99.2%, respectively. Glomerulonephritic and urological hematuria were correctly diagnosed by counting the urinary red cells with doughnut-like shape in acidic and concentrated urine. This method seems to be superior to others in diagnostic rate, simplicity and clarity.  相似文献
