Subvenous external iliac lymph node dissection is an essential element for the staging of prostatic cancer. 7 to 30% of patients with intracapsular prostatic cancer have lymph node metastases despite normal imaging examinations. Laparoscopic surgery allows lymph node dissection through a limited incision. Sixteen patients underwent laparoscopic lymph node dissection (LLND) for prostatic cancer. The mean duration of the operation was 100 +/- 50 minutes (35-180 min: 130 minutes for the first nine operations, then 60 minutes for the last seven operations). One patient died on the second day from a cerebral vascular accident. There was one technical failure (pneumoperitoneum leak), one vascular injury, one ureteric injury, one transient paresis of the obturator nerves and one case of perineal lymphoedema. The mean number of lymph nodes removed in bilateral lymph node dissection was 7.5 +/- 2 (14-20) per patient. Three patients had lymph node metastases. The mean hospital stay related to laparoscopy was 4 +/- 2 days with a median of 2 days. Laparoscopic surgery, like any conventional or innovative surgical technique, requires specific training to become safe and effective. It allows complete histological examination of the lymph nodes removed and planning of prostatectomy, which may be subsequently performed through a perineal approach.

Between 1970 and 1989, total prostatectomy was performed in 31 patients with prostatic cancer at the Department of Urology, Tokyo Metropolitan Fuchu Hospital. These cases were composed of 4 cases of stage A, 8 cases of stage B and 19 cases of stage C. The surgical procedures were perineal prostatectomy in 25 cases, combined method of perineal and retropubic prostatectomy in 5 cases and transsacral prostatectomy in one case. Blood loss was 762 ml on the average. Blood transfusion was unnecessary in 15 cases all of whom underwent perineal prostatectomy. Endocrine or radiation therapy were administered after total prostatectomy to 23 or 13 cases, respectively. Postoperative complications included early postoperative death due to apoplexy in 1 cases, recto-vesical fistula in 1, bladder neck or urethral stricture in 9 (mild 7, severe 2) and urinary incontinence in 20 (mild 13, moderate 4, severe 3). Frequency and grade of urinary incontinence tended to become higher as the pathological stage progressed. The 5-year survival rates for clinical stage A and B, and C were 83% and 63%, respectively. We conclude that total perineal prostatectomy was less traumatic operation for prostatic cancer, and would be indicated in clinical stage A and B for radical operation and in stage C for one of the combination therapy.

The outcome for the first 57 successive patients who underwent total perineal prostatectomy for clinically localized prostate cancer at the Virginia Mason Clinic and who have been followed up for a minimum of 15 years is reviewed for evaluation of the long-term impact of this operation on the disease. Twenty percent of the patients had pathologic stage C disease. Recurrence developed in 11 of the 55 patients (20%) who could be evaluated, and death from prostate cancer occurred in 6 (11%) during this interval. The actual observed overall survival at 15 years or more was 60%, the actuarial survival 67%, and the cause-specific survival 89%. The current morbidity of this operation was evaluated by review of the last 50 consecutive patients who underwent this procedure and had follow-up of at least 6 months. Operative time averaged 140 minutes, and blood loss averaged 660 ml; 22% of the patients required a transfusion. Average postoperative hospitalization was 5 days. Two patients required a temporary colostomy for unrecognized rectal injury, and 2 developed a stricture requiring more than one dilation. Three patients (6%) wear pads for mild stress incontinence. One patient died of a cerebral vascular accident.

Although no absolute certainty exists about the role of nutrition in the etiology of cancer, many facts in favor of the relationship became available during the last decades. Correlation studies, experimental work and to a lesser extent case-control studies made it possible to clarify the role of certain nutrients and foods in carcinogenesis. The most important cancer sites where nutrition could play a role are esophagus, stomach, colon, rectum, prostate and breast. Esophageal cancer is of a very complex etiology, in which alcohol intake plays an important role, at least in western countries. The cancer-promoting properties of alcohol intake are enhanced by smoking. Three factors from nutrition are probably related to stomach cancer, namely salt, nitrate/nitrite and vitamin C. Salt is caustic to the stomach mucosa, resulting in atrophic gastritis. Salt is also co-carcinogenic and stomach cancer-promoting in experimental animals. Nitrate is probably important at the stage of atrophic gastritis, where bacterial overgrowth, due to the high pH, converts nitrates in nitrites, making the loco synthesis possible of potent nitrosocarcinogens. Vitamin C inhibits the latter step. The epidemiological evidence for the role of those factors is provided. The most important among them is the strong and consistent association of stomach cancer mortality with stroke. Rectum, colon, prostate and breast cancer are related in some way to fat intake. They all seem positively related to saturated fat intake, whereas breast cancer is probably also promoted by polyunsaturated fat intake. However, polyunsaturated fat seems to be without effect on rectum cancer. Colon and prostate cancer are probably also influenced by polyunsaturated fat but to a lesser degree than breast cancer. An important argument for this are the positive ecological correlations between changes in rectum, colon and breast cancer mortality from 1968 on, and changes occurring in coronary heart diseases, stroke and diabetes mortality. Those six types of mortality are decreasing, or only slightly increasing in the USA, Belgium, France, the Netherlands, etc. They are strongly increasing in East European countries. The intake of saturated fat has generally decreased in the first group of countries, and has markedly increased in the second group.(ABSTRACT TRUNCATED AT 400 WORDS)

We analysed hospital use for 58 common clinical conditions in the medical specialties, using data from the two districts covered by the Oxford record linkage study 1968-1986. Episode rates, person rates, and ratios of multiple admissions per person were computed. In young adults, poisoning was the most common reason for admission. In older adults, the most common clinical conditions included atherosclerotic diseases and smoking-related lung diseases. Comparing the first and last time periods studied, admission rates increased by 10% or more in 37 of the 58 conditions, including 7 of the 10 conditions with the highest overall hospitalization rates. Conditions in which admissions increased by 10% or more included myocardial infarction, other ischaemic heart disease, chronic obstructive lung disease, asthma, pneumonia, diabetes, poisoning, dementia, prostate cancer and breast cancer among others. Workload declined by 10% or more in 13 conditions, including stroke, subarachnoid haemorrhage, hypertension, thyrotoxicosis, acquired hypothyroidism, and tuberculosis. Secular trends in hospital use are generally attributable either to changes in disease frequency in the population or to changes in clinic- or hospital-based technology and practice.

The new anthracyclin, menogaril [7-(R)-0-methylnogarol], is reported to produce less cardiotoxicity than doxorubicin after multiple doses. This study was designed to assess acute hemodynamic changes during the first administration of menogaril and to relate these changes to plasma concentrations. Menogaril (200 mg/mg) was infused over 90 minutes to 4 patients with metastatic colon or prostate cancer. Cardiac output (CO) and stroke volume (SV) were measured noninvasively by Doppler ultrasound. Menogaril plasma concentrations were measured by HPLC and a 3-compartment mammillary model was used for pharmacokinetic analysis of the results. Steady-state volume of distribution, elimination clearance, and elimination half-life averaged 1,114 +/- 340 l/m2, 38 +/- 16 l/h/m2 and 40.3 +/- 30.3 hours, respectively. All patients were normotensive (baseline blood pressure = 135 +/- 10/73.5 +/- 8 mmHg) and ejection fractions were in normal range (EF = 68 +/- 7%). Transient increase in mean arterial pressure (MAP) from 93 +/- 3 to 107 +/- 4 mmHg (p < or = 0.001) were seen during and shortly after the end of menogaril infusion in all patients. Heart rate (78 +/- 5 min-1) remained constant. CO fell slightly and total peripheral resistance (TPR) increased by 36.8% in the last 2 patients. The increase in MAP was analyzed by a linear-effect model and averaged 0.028 +/- 0.017 mmHg per ng/ml of menogaril in the hypothetical biophase. The half-life for menogaril equilibration between plasma and this biophase was 41 +/- 22 minutes. We conclude that during acute administration of menogaril, blood pressure increases transiently secondary to an increase in TPR.(ABSTRACT TRUNCATED AT 250 WORDS)

Assessment of the pelvic lymph node status is a major concern in prostatic cancer staging. In spite of a normal abdominopelvic CT scan examination in patients with organ-confined disease, 7-30% will have lymph node metastases at pathological examination and will not benefit from radical prostatectomy. Laparoscopy enables pelvic lymph node dissection via a minimally invasive approach. Twenty-nine patients underwent laparoscopic pelvic lymph node dissection (LPLND) for prostatic cancer staging. The average duration of the bilateral dissection was 90 +/- 40 min (range 35-180 min). One patient died of a stroke on postoperative day 1, without local complication. The peroperative complications were 1 injury of the external iliac vein, 1 ileal injury, 1 ureteral injury, all 3 (11%) requiring immediate or delayed laparotomy. One patient had a self-resolving bilateral obturator nerve paresis. A previously irradiated patient had perineal lymphedema for 4 weeks. The average number of lymph nodes removed was 8.4 +/- 3.4 (range 4-17) for bilateral LPLND. Five patients had lymph node metastases. The median length of stay for patients undergoing LPLND as a single procedure was 2 days (range 2-11 days). After an operational period, during which the complication rate was relatively high, we now consider LPLND as a safe and effective procedure for the staging of patients with organ-confined prostatic cancer, but considering the increased risk of complications during the application period, we do not encourage the generalization of this technique which should remain restricted to some particular strategies, as in combination with perineal radical prostatectomy.

In a study of the disease pattern of the elderly in Rwanda, all patients aged 60 or more, hospitalized in a one-year period at the Medical Department, University Hospital, Butare, were examined prospectively. One hundred and ninety-two patients were included; most were subsistence farmers having a mainly vegetarian diet and living in large families. Infections (37.5% of the patients) and liver cirrhosis (31.8%) were the problems most frequently encountered. Primary hepatocellular cancer was diagnosed in 5.7% of the patients and was the most frequent malignancy. The hospitalized elderly occupied 17.5% of the available beds in the Medical Department. Their disease pattern was different from that of younger patients, making heavier demands on the medical resources. Malaria and upper intestinal inflammation were less frequent in the elderly; liver cirrhosis, primary hepatocellular cancer, pneumonia, prostatic cancer, cardiovascular pathology, chronic renal pathology and chronic lung disease were more prevalent. Several age-related conditions frequently observed in industrialized countries (e.g. coronary heart disease, stroke, gallstones, renal cysts, dementia) were rare. The study thus illustrates the concept of 'secondary aging': to the primary changes induced by the aging process, additional alterations are added which depend upon the environment and the lifestyle, resulting in a varying disease pattern. Health policies thus must take into account that the demographic transition in developing countries may result in a pattern of diseases different from that seen in industrialized countries; care must be taken when transposing data obtained from elderly populations in industrialized countries.

The syndrome of pituitary apoplexy has been reported to occur after the administration of several different medications. We report a case in which pituitary apoplexy developed shortly after the administration of leuprolide in a patient with prostate cancer. Leuprolide is a potent gonadotrophin releasing hormone (GnRH) analogue used to suppress leuteotrophic hormone (LH) and testosterone levels in patients with metastatic prostate cancer. LH and testosterone levels actually rise in the first week after its administration before becoming suppressed. We suspect that this acute stimulating effect of leuprolide is linked to the acute onset of pituitary apoplexy in a patient with a possible gonadotrophoma.

Older African Americans constitute an expanding part of the elderly population in the United States. Although socioeconomic factors affect longevity and functional status more than race, African-American elders, as a whole, show poorer health status, as well as greater levels of financial strain and care-giver burden. Incidence rates of hypertension, heart disease, stroke, end-stage renal disease, dementia and prostate cancer are higher among African Americans than among the white population. The incidence of depression, however, is lower. Cancer survival rates are also lower, in part because of lower rates of cancer screening in this group. Physicians should carefully choose instruments to assess cognitive and physical status in African-American elders. The Activities of Daily Living scale and the Short Portable Mental Status Questionnaire are two tools that have been specially tested and shown to be reliable and valid in this population group. The Geriatric Depression Scale is a useful diagnostic tool that is quick to use in a busy office practice. Taking the time during an initial visit to understand the patient's values and perceptions of health and illness builds a sense of comfort and trust that will set a positive tone for the entire doctor-patient relationship and may empower the patient to take positive steps to improve health habits.
