Pathogenesis of hypertension in Cushing's syndrome has remained controversial. A 56-year-old Japanese man with Cushing's syndrome due to adrenal carcinoma has been followed up for more than 6 years. During the followup period, left adrenalectomy and hemihepatectomy due to metastatic lesion were performed. Blood pressure, serum cortisol, and urinary excretion of 17-OHCS, as well as other routine biochemicals, have been measured periodically. These data revealed that there is a marked correlation between the levels of blood pressure and serum cortisol or urinary excretion of 17-OHCS. This finding suggests that cortisol production by tumor is a determinant factor in hypertension in Cushing's syndrome.

We experienced 41 cases of Cushing's syndrome (12 males and 29 females, 15 years old - 65 years old) during the last 20 years. These included 20 patients with unilateral adrenal adenoma (Cushing's syndrome), 19 patients with bilateral adrenal hyperplasia (Cushing's disease), one patient with adrenal carcinoma and one patient with primary adrenocortical nodular dysplasia (PAND). Moreover, these cases included some special ones, i.e. 5 cases with destructive thyroiditis after treatment, 2 cases with aggravation of arthritis after treatment, a case of Carney's complex with PAND, one case with paradoxical response to dexamethasone, and one case combined with empty sella syndrome. The most specific clinical signs were moon face (95% occurrence), hypertension (95%) and subcutaneous bruising (80%). Other significant signs were eye edema (66%), buffalo hump (68%), subcutaneous purpura (63%) and osteoporosis (49%). Skin striae was not a common sign in our cases (41%). Renal stone was observed in only 20% of our patients but was a significant sign in this syndrome. There was no difference in the occurrence of each clinical sign between Cushing's syndrome and Cushing's disease. The elevation of white blood cell count (WBC) and serum sodium, a decrease of serum potassium, and a decrease of reabsorption of phosphate (%TRP) were observed. Thyroid-stimulating hormone (TSH) and human growth hormone (HGH) were suppressed in patients with Cushing's syndrome and patients with Cushing's disease. These results were consistent with those of previous reports. However, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin (PRL) were high in those patients with Cushing's syndrome and those with Cushing's disease. Oral glucose tolerance test was carried out in 34 patients before and after treatment. Thirty-one percent of those had diabetes mellitus and 26% had impaired glucose tolerance (IGT). The response of IRI in this test was high in patients with Cushing's syndrome and patients with Cushing's disease, and decreased 4 weeks after treatment in those with Cushing's syndrome but remained high in those with Cushing's disease. Plasma ACTH level and urinary 17-OHCS excretion were significantly higher in Cushing's disease than in Cushing's syndrome. During an 8mg-high-dose dexamethasone suppression test, urinary 17-OHCS excretion in 13 of 14 patients with Cushing's disease (93%) was suppressed by more than 50% of baseline on the second day of testing. However, all of 18 patients with Cushing's syndrome, who had an 8mg-dexamethasone suppression test, failed to suppress urinary 17-OHCS by 50% of baseline.(ABSTRACT TRUNCATED AT 400 WORDS)

Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea, vomiting, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary sodium excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

Anterior ischemic optic neuropathy is an uncommon and devastating event that can result in unilateral or bilateral blindness. It has been reported as a complication of ophthalmologic or general surgical and cardiothoracic procedures as well as a spontaneous event in severe systemic disease. Aggravating intraoperative factors include anemia, hemorrhage, hypotension, preexisting small-vessel disease, and increased intraocular pressure. We present a case of anterior ischemic optic neuropathy as a complication in a 48-year-old man undergoing extensive resection of recurrent carcinoma of the head and neck. Possible contributing risk factors in our patient include preexisting hypertension, intraoperative blood loss, previous radical neck dissection with venous compromise, intraoperative head and neck edema, and the use of tightly adherent plastic bubble-type intraoperative eye protection. The possible pathogenesis of this devastating complication and recommendations for prevention and management of anterior ischemic optic neuropathy are described.

During the past 20 years (1970-90), we had 24 patients with pheochromocytoma: 19 diagnosed clinically and 5 post-mortem. Their ages ranged from 17 to 74 (mean, 43.2 years). Males (n = 14) outnumbered females (n = 10), a 1.41:1 M:F ratio. A majority were symptomatic (95%), with a typical triad of headaches, palpitations and diaphoresis. Most frequent finding was hypertension (95%). It was sustained in 60% and paroxysmal in 35%. In 6 patients (25%) pheochromocytomas were bilateral, all familial. Fifteen were solitary adrenal tumors (63%); 3 (12.5%) were extra-adrenal: 2 intra-abdominal, and 1 cardiac paraganglioma of right atrium. Of 6 familial cases, 4 were associated to Von Hippel-Lindau (VHL) disease, while 2 were multiple endocrine neoplasia (MEN-II) patients. All familial cases were bilateral and in the adrenals. There were no malignancies. Among the 19 clinical cases pre-operative Dx was made by positive urine VMA or catecholamines urine levels: (95 and 100% sensitivity respectively). Preoperative visualization by CT or MRI was done in 62% of the most recent patients. In 5 earlier cases the diagnosis was made post mortem: 3 died of cerebral hemorrhage, 1 with a pons infarct and 1 with congestive heart failure (CHF). There were 2 post-operative deaths and another died 13 years later from thyroid medullary carcinoma. Of the 19 operated, 13 (68%) were cured. Thus pheochromocytomas retain considerable morbidity and some mortality. These rare tumors constitute a clinical diagnostic challenge yet a rewarding therapeutic experience for the alert physician.

A 68-year-old man with hypertension was admitted to the Shiga Kenritsu Seijinbyo Center for further examinations, because abnormal opacity in the right upper lung field was accidentally revealed by chest X-ray. Chest CT demonstrated two separate mass shadows, one 31 X 27 mm, the other 10 X 10 mm in size, both of which were located in the posterior segment of right lung. Specimens from transbronchial biopsy of the larger mass was histologically diagnosed as adenocarcinoma. He underwent right upper lobectomy with hilar and mediastinal lymph nodes resections. Postoperative patho-histological study showed the larger mass to be poorly differentiated adenocarcinoma, the smaller one, small cell carcinoma respectively, and no continuity between the two masses. Lymph nodes metastasis were negative. Any malignancy was not detected by brain CT, abdominal CT and any other gastro-intestinal examinations, and he was diagnosed to have double primary lung cancers in the same one segment. In this report, we discussed the diagnosis and treatment of double primary lung cancers, and reviewed the literatures.

The long term complications of renal transplantation were assessed in 36 patients who had lived for 10 or more years with a functioning renal transplant. Thirty-three patients were alive with a mean plasma creatinine of 0.13 mmol/L (SD 0.07). A 62 year old women died from a myocardial infarction 11 years after transplantation and two women developed chronic rejection and returned to dialysis after 17 years. Nineteen patients have required antihypertensive therapy, five have suffered ischaemic heart disease and two a cerebrovascular event. Malignancy has developed in 13 patients, with four having two or more organs involved. Skin cancers (9 squamous cell, 4 basal cell) were present in all 13 patients and recurred in six. The other malignancies included carcinoma of cervix (2), cervix and bladder (1) and thyroid (1). Three patients have required parathyroidectomy for autonomous hyperparathyroidism, two splenectomy for hypersplenism, and one bilateral hip replacement for avascular necrosis of the femoral heads. The development of hypertension, vascular disease and malignancy are the most important long term complications after renal transplantation. Strategies must be formulated to reduce the morbidity and mortality from these causes.

A randomized controlled trial was carried out to elucidate the enhancement of chemotherapeutic effect of induced hypertension chemotherapy (IHC) using newly synthesized angiotensin II human (TY-10721) in advanced gastric carcinoma under multi-institutional cooperation. In IHC, the drugs were administered under the hypertensive state induced and maintained by the continuous infusion of TY-10721. The regimen for the trial was as follows: adriamycin (33 mg/m2, day 3), 5-fluorouracil (330 mg/m2/day through day 1 to 3, 8 to 10) and mitomycin C (5 mg/m2, day 8). It was repeated every 4 weeks. Of 67 registered cases, 62 eligible patients were randomized to either IHC arm or control arm (non-IHC) in which the drugs were administered by an ordinary i.v. injection. According to the Criteria of Japanese Society for Cancer Treatment, the response rate of IHC group was 31.3% and that of non-IHC was 6.7% with statistically significant difference (p less than 0.05; chi 2c). There were 4 CR and 6 PR in 32 eligible cases of IHC and 2 PR in 30 of non-IHC. Clinical characteristics of patients and toxicities were not different in both groups. Clinical advantage of IHC was confirmed by increase of the response rate in this trial.

A 41-year-old woman was hospitalized for evaluation of diabetes mellitus and hypertension. The hormonal and radiological examinations revealed that she had pheochromocytoma of bilateral adrenal gland and medullary carcinoma of thyroid gland. Therefore, she was diagnosed as having Sipple's syndrome. She had no definite familial history, but her two sisters, already dead, had been strongly suspected of having had pheochromocytoma. First, bilateral adrenalectomy was performed and secondly, total thyroidectomy, excision of parathyroid and cervical lymph node dissection were performed. Histopathological diagnosis was pheochromocytoma of bilateral adrenal gland, medullary carcinoma of thyroid gland and chief cell hyperplasia of parathyroid gland. We report a case of Sipple's syndrome, which probably is the 88th case in Japan, with the review of the previous Japanese literature.

From July 1985 to January 1989, 133 patients underwent endometrial sampling for evaluation of post menopausal bleeding (PMB). Of these patients, 114 (85.7 percent) showed benign histology with an average age of 58.6 years. Nineteen (14.3 percent) were malignant, all of which showed endometrial carcinoma. The average age was 65. In addition, 26.3 percent of patients with carcinoma had higher grade of tumor at hysterectomy when compared with the preoperative biopsy. The average volume of tissue removed at curettage was significantly greater in those with carcinoma. Hormonal therapy, duration of symptoms, hypertension, obesity or diabetes were not significant risk factors for carcinoma in our series. PMB remains a major symptom that may predict endometrial carcinoma and must be evaluated. In those patients with carcinoma, intraoperative evaluation of the uterus for tumor grade and depth of invasion is important in determining the extent of surgery.
