In an attempt to evaluate the effect of induced hypertension chemotherapy (IHC) using angiotensin II human, histopathological analysis was performed on stomachs excised from thirteen patients who had advanced gastric carcinoma and were submitted to presurgical cancer chemotherapy. IHC was introduced in randomly chosen eight patients and, in the remaining five patients, chemotherapy was designed under conventional conditions. A common regimen comprising 5-fluorouracil, adriamycin, mitomycin C was applied in both the IHC and non-IHC groups. The clinical effect in these patients, assessed prior to surgery, gave rise to the confirmation of three CR patients in the IHC group, while in the non-IHC, PR was the highest score. Histological examination illuminated a patient in the IHC group in whom no viable carcinoma cell proved to remain in the excised stomach, a state meeting the requirements for the highest (Grade 3) effectiveness according to the standard given by the Japanese Research Society for Gastric Cancer. In another two patients of the same group, the effect was Grade 2, i.e., the degeneration and loss of carcinoma cells in the major part of tumor. In contrast, the effect in the non-IHC group was Grade 1b at the highest, where chemotherapy-associated degeneration and necrosis did not predominate over one third of tumor area. Thus, the mean histological score was apparently higher in the IHC than in the non-IHC group, with a difference significant at p less than 0.05 by Wilcoxon's test. Patients clinically evaluated as effective tended to be so pathologically as well, as shown by Spearman's rank correlation test which gave a significant correlation between the clinical and pathological scores.

Recurrent haemospermia is often regarded as "essential". Following routine diagnostic procedures, we found an associated factor in 54 of 72 patients (75%). With one exception (prostatic carcinoma), the benign character of the disease was confirmed. Urogenital infection was the most frequent concomitant finding (50%); in 26 men chronic prostatis was diagnosed. Other disorders such as hypertension and coagulation disorders played a minor role. Additional investigation of the prostate gland and seminal vesicles by transrectal prostatic ultrasonography revealed persistent asymmetry of the latter glands as the main finding in 20 men (28%). In every case seminal vesicle carcinoma was excluded; haemorrhage due to cystic distension, inflammatory lesions or ductal obstruction was associated in all cases with congenital abnormalities, chronic urogenital infection, coagulation disorders or hypertension.

The case-control method was applied in order to test how various types of diet as well as past diseases, tobacco smoking and occupational exposure may affect the risk of incidence of corpus uteri cancer in the population of natives and among immigrant women. The highest risk of incidence was noted in the group of natives persistently using a diet rich in meat, animal fat, amylum meals and sugar but lacking raw vegetables. Such a high risk was not observed in the group of immigrant women what might be caused by more frequent change of the type of diet. Some past diseases (arterial hypertension, diabetes, diseases of organs of reproduction and urinary system) do affect a relatively high risk of corpus uteri carcinoma in both populations. However, no noteworthy results have been obtained in the risk of corpus uteri carcinoma as far as tobacco smoking and occupational exposure are concerned.

1. Of 93 patients with primary aldosteronism seen during a 20 year period, 52 had an aldosterone-producing adenoma (APA) removed (five more await surgery), 14 had bilateral adrenal hyperplasia (BAH), three had glucocorticoid-suppressible hyperaldosteronism (GSH), one had adrenal carcinoma and 18 are yet to be categorized. 2. Seventy-three presented with hypertension and hypokalaemia. Others had markedly suppressed renal venous plasma renin activity (PRA) or elevated plasma aldosterone (PA)/PRA ratio, in new or resistant hypertensives. 3. The PA/PRA ratio was the most reliable screening test. 4. Diagnosis depended on the failure of suppression of aldosterone by salt loading and fludrocortisone. 5. Differentiation of BAH from APA depended on adrenal venous sampling comparing adrenal and peripheral venous PA/cortisol ratios. 6. A new familial variety of primary aldosteronism is described, with two affected members in each of three families. 7. Primary aldosteronism should be looked for in resistant and low-renin hypertension as well as in hypertension with hypokalaemia, and other family members should have PA/PRA measured if they are hypertensive.

In contrast to pulmonary parenchyma metastases or lymphangitic carcinomatosis, neoplastic emboli of small pulmonary arteries and capillaries frequently go unrecognized and are only discovered at autopsy. Five patients (48 +/- 12 years old) were admitted to 3 intensive care units for severe acute respiratory failure and died between the first and the tenth day following hospitalization. Each patient had a history of rapidly progressive dyspnea, and physical examination showed clinical evidence of right ventricular failure. The lungs were clear on chest X-rays and the ECG revealed sinus tachycardia with a right QRS axis. The mean partial pressures of oxygen (PaO2) and carbon dioxide (PaCO2) were, respectively, 50.8 +/- 9.1 mm Hg and 22.2 +/- 2.4 mm Hg. A swan-Ganz catheter, inserted into 4 patients, revealed pulmonary arterial hypertension (55, 43, 37, 28) with capillary wedge pressure within the normal limits and cardiac output normal or low (3.0, 3.8, 4.4, 5.0 l/min). Pulmonary angiograms from each patient showed decreased distal lung perfusion without any proximal defects suggestive of pulmonary embolism. The inferior vena cava always appeared clear. Malignant cells were found upon autopsy (4 cases) in the lumina of the pulmonary arterioles and the primary site of the cancer was determined in 3 patients (2 hepatomas and 1 pancreatic carcinoma). The last patient had a known breast cancer with bone marrow metastases and clinical, hemodynamic and angiographic evidence of neoplastic emboli. The clinical course of neoplastic emboli can suggest acute pulmonary embolism, but the diagnosis can only be advanced after pulmonary angiography, especially if the patient is to have a cancer.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary aldosteronism (PA) is a relative new endocrine disease that account for almost 1-2% of the hypertensive population. In spite of the large number of reports there is still disagreement around the preoperative diagnosis and surgical treatment. In a nineteen year period from 1970 to 1989, 34 patients came to our Department with a diagnosis of Primary Aldosteronism. 18 patients were female. Mean age at time of diagnosis was 45.5 yrs. (range 27-67 yrs.). Mean follow-up was 71 months (range 1-227 months). Follow-up was achieved in all patient. Hypertension and hypokalemia were discovered in all patients. Three patients had extremely low values of potassium and presented severe metabolic, cardiac and neurologic troubles. Localization procedure techniques improved during this period of time and at this moment CAT scan appears to be the most accurate method. Flank incision was the approach of choice in all but four patients. No postoperative complications were recorded. Histology demonstrated an incidence of adenomas according to the literature. One patient had an adrenal carcinoma with functioning metastases. He was operated on several times in order to remove the functioning node metastases but finally died with widespread disease four years after the first surgical treatment. Another patient in this series died three years after the operation for an unrelated event. In 29 patients hypertension and hypokalemia disappeared while in two patient, one with an adrenal carcinoma hypertension increased. Primary aldosteronism is a rare endocrine disorder whose incidence is increased in the last years because of the improvement in diagnostic procedures.(ABSTRACT TRUNCATED AT 250 WORDS)

In a retrospective study, patients with end-stage renal failure from analgesic-associated nephropathy - 55 on regular dialysis treatment and 12 after renal transplantation - were under observation for 57 and 33 months, respectively. Of these 34 patients on chronic hemodialysis had suffered from different cardiovascular diseases. Hypertriglyceridemia was diagnosed in 62% of the patients, arterial hypertension requiring antihypertensive therapy in 44%. In three patients (5%) carcinoma of the urinary bladder were diagnosed. The leading causes of death in 21 patients included cardiovascular diseases (29%), hyperkalemia (19%), sepsis, and malignant tumors (14% each). Rejection occurred in 3 out of 12 patients after renal transplantation. Again, cardiovascular morbidity was high (58%) with coronary heart disease being present in 33% of the patients. Hypertriglyceridemia was observed in 5 out of 6 patients, antihypertensive therapy was needed in 50%. One patient died from primary pulmonary hypertension.

An autopsy case of hemolytic uremic syndrome after treatment with antineoplastic agents for advanced gastric carcinoma is reported. A 70 year-old woman underwent partial gastrectomy for gastric carcinoma on April 16, 1987 (P0H0S2N4, Stage IV). She was treated with Mitomycin C (MMC), UFT, OK-432 and PSK as post operative chemotherapy. Total doses were 60 mg of MMC, 33.9 g of UFT, 55 KE of OK-432 and (507 g) of PSK. She suffered from occult blood in urine in September 1987, thrombocytopenia and anemia in October, edema and hypertension in November and died due to acute renal failure and pulmonary failure on December 5, 1987. It seemed that the cause of death was hemolytic uremic syndrome induced by antineoplastic agents.

The incidence of uterine cervical carcinoma, though decreasing in many cities of China, dose not show any diminution in the rural areas where it appears to be high in some regions. Therefore, radical hysterectomy is particularly important for the patients with cervical adenocarcinoma and squamous adenocarcinoma which are insensitive to chemotherapy and radiotherapy. The operation is effective in the treatment of early cervical carcinoma and even late carcinoma when the procedure is combined with extraperitoneal radical lymphadenectomy, radiotherapy and chemotherapy reinforced by the traditional Chinese medicine. This operation gets rid of technical difficulties in manipulating the deep pelvic cavities of obese patients, and is suitable for those patients with general weakness, heart and renal diseases, hypertension, severe tuberculosis complicated by the poor tolerance of the abdomen or fear to transabdominal procedures. The detailed procedures of the operation and its results are described.

The clinical efficacy and indications for Angiotensin II (AT II)-induced hypertension chemotherapy were evaluated as a drug delivery system in 101 patients with advanced carcinoma. The sites of primary tumor studied included stomach (44), pancreas (18), colon (16), esophagus (6), bile duct (4), liver (3), breast (7) and 3 other single organs. Seventy four cases had distant metastases (lymph node (25), liver (29), peritoneum (16), and lung (4)). Additionally, the protocol was used 12 cases as postoperative adjuvant chemotherapy and 15 cases following exploratory laparotomy. The blood pressure was elevated to a level 1.5 times base-line. The regimens used consisted of MMC + ADR (55), FAM (38) and CDDP (8). The dosages administered were MMC 7 mg/m2, ADR 14 mg/m2 and 5-FU 350 mg/m2. The cancer chemotherapy protocol with AT II was repeated for an average of 2.6 cycles with a 2-3 week interval. The drug concentration in tumor tissues was increased 1.7 fold by AT II treatment. The response rate was 15.8% (CR 7 and PR 9), and in those patients with lymph node, liver and peritoneal metastases was 48.0, 6.9 and 6.3%, respectively. The serum levels of tumor markers decreased in 9 patients. Subjective symptoms, such as hoarseness, edema and pain, were improved. The mean survival in patients with distant metastasis who responded was 343 days, and in nonresponders was only 168 days (p less than 0.05). The side effects of this therapy were slight, typically being grade 1 and 2. Thus, the chemotherapeutic agents studied in conjunction with AT II were effective in patients with lymph node metastasis. Additionally, this regimen could be performed safely with minimal side effects.
