Setting targets: a three-stage model for determining priorities for health promotion

This paper describes a three-stage model for setting targets for health promotion. The model was developed in 1992 in response to the need to identify priority areas for health promotion for women in the Hunter Region of New South Wales. The approach enabled epidemiological data and views from the community to be synthesised and integrated with those of experts from health and social services (key informants), using a nominal group process. The reliability of the method was investigated by replicating the process with two groups of key informants. There was considerable commonality in the targets generated by the two groups. The process resulted in the identification of seven targets that reflected the concerns of the community and local experts as well as the health priorities suggested by local epidemiological data. The model used could be adapted for determining priorities in a wide range of health and health care settings, where available resources restrict the range of services or activities which can be offered.

Effect of calcium replacement on the hemodynamic changes associated with high dose interleukin-2 therapy.

Administration of high-dose IL-2 results in hemodynamic changes that are similar to those seen in septic shock. These include a decrease in systemic vascular resistance (SVR) with a resultant drop in mean arterial pressure (MAP). Hypocalcemia is seen in septic shock and with IL-2 administration. Calcium replacement in septic shock has been reported to result in hemodynamic improvement; we therefore administered calcium to patients receiving high dose IL-2 to correct ionized hypocalcemia. Five consecutive patients underwent invasive hemodynamic monitoring before and during IL-2 administration. Calcium chloride was administered to correct ionized hypocalcemia, and hemodynamic parameters were monitored before and after calcium administration. Ionized hypocalcemia was associated with an elevation in parathyroid hormone levels. There was no toxicity related to the administration of calcium. An improvement in the MAP and SVR was seen early and late (after a dose of IL-2 was held) in the IL-2 treatment cycle; there were minimal effects at other points. Because of the potential hemodynamic benefit of calcium replacement, we recommend that ionized hypocalcemia be corrected in patients receiving high-dose IL-2.     

Results of the tension-free vaginal tape procedure for stress incontinence: Patient''s perspective

BACKGROUND: To evaluate the results of the tension-free vaginal tape procedure (TVT) from a patient's perspective. METHODS: Between May 1999 and January 2002, 90 patients underwent a TVT for genuine stress incontinence (GSI) and mixed incontinence. Prior to the procedure, GSI was confirmed by clinical examination and urodynamic studies. Results were then audited from patient notes and the same patients were sent questionnaires to examine results from a patient perspective. RESULTS: Overall response rate to the questionnaire was 70 (77%). The mean age of the patients was 50.4 years (range 31-83 years). Sixty-one patients had spinal anesthesia, seven had general anesthesia and two had local anesthesia. Mean hospital stay was 3.36 days (range 2-14 days) and mean period from the operation to the time of the survey and audit was 16.34 months (range 3-28; SD 6.92). Thirty-nine (56%) of the 70 patients who answered said that the operation had cured their incontinence, 16 (23%) had an improvement in their symptoms, 7 (10%) had worsening of their symptoms and 8 (11%) felt that the operation did not make any difference. The overall success rate according to the patients' perspective was 79%, whereas our audit showed an overall success rate of 86% (77% and 82%, respectively, when we compared only the 66 patients who had both notes and replies available for analysis). CONCLUSION: Although a patient's perception regarding the success of TVT tends to differ from that of a clinician, it was not found to be statistically significant (P = 0.22, McNemar test). The TVT is a very successful operation, but realistic cure rates should be offered to patients.     

Early detection of colorectal cancer: a profile of current practice.

This study examines the prevalence of colorectal cancer screening among individuals in the general community. The survey was undertaken as part of a large scale general population survey of health practices and attitudes. A sample of 1090 people aged 40 years and over with no previous history of colorectal cancer or other predisposing condition was interviewed. Only 56% of this group reported that they regularly checked their bowel movements, the toilet bowl, or the toilet paper for signs of rectal bleeding. Only 13% could recall a doctor ever advising them to check for rectal bleeding; and 21% could recall a doctor asking them if they had ever noticed blood in their bowel movements. More involved practitioner-based procedures, such as digital rectal examination, fecal occult blood testing, endoscopy, and barium enema, were reported by only a minority of participants. Analysis of screening rates in the 9.3% of people who reported a family history of colorectal cancer revealed that this higher risk group was no more likely to be screened than those at average risk.     

Hodgkin disease: CT of the thymus

The computed tomography (CT) scans in two groups of patients with Hodgkin disease were reviewed to determine the frequency of thymic enlargement. In 50 CT scans from 50 patients with evidence of thoracic disease on CT scans who were examined for primary staging, the thymus was enlarged in 15 of 50 (30%). Fifty CT scans were obtained from 44 patients at the time of 50 separate episodes of known or suspected relapse. Relapse occurred in the mediastinum in 12 episodes, lung parenchyma in five, and both sites in one. Thymic enlargement thought to be due to involvement by disease was present in seven of 18 (38%). Mediastinal disease was associated with thymic enlargement in all but one patient in whom a thymic cyst developed after radiation therapy. Differentiation of thymic enlargement from enlarged superior mediastinal lymph nodes was easily made in all but two patients. Thymic enlargement in the absence of lymph node enlargement may indicate a different disease, since isolated Hodgkin disease of the thymus is uncommon. Primary thymic tumor should be considered initially, whereas after treatment, rebound hyperplasia of the thymus may be the cause of enlargement.     

Solid and papillary epithelial neoplasms of the pancreas: CT findings

Five female patients and one male patient with solid and papillary epithelial neoplasms of the pancreas were examined with computed tomography (CT). The mean age of the patients was 27 years (range, 13-46 years). All cases showed well-encapsulated, round or lobulated masses consisting of both cystic and solid areas. Cystic portions showed CT numbers that suggested hemorrhagic necrosis. There were no internal septations within the masses. In three tumors located in the head of the pancreas, dilatation of the biliary tree was absent or minimal, although the masses were large. Two tumors contained calcifications. One tumor demonstrated metastatic deposits in liver and lymph nodes. Metastatic masses appeared similar to the primary pancreatic mass. Solid and papillary neoplasm of the pancreas should be the primary diagnostic consideration when characteristic CT findings are detected in a young female patient.     

Detection of alcohol-related problems in general practice.

While primary care has considerable potential as a site for detecting and intervening for alcohol-related problems, few doctors currently identify these problems. The judgments of eight primary care physicians about alcohol-related problems in 371 of their patients were compared with the patients' responses to the Short Michigan Alcoholism Screening Test (SMAST) and the CAGE. The CAGE classified 11.4% of the patients as alcoholics and the SMAST identified 23.9% as probable alcoholics. However, the doctors identified only a small proportion (7.0%) of their patients as having any level of alcohol-related problem. The doctors did not identify 65.0% of CAGE-defined alcoholics and 82.3% of those patients classified by the SMAST as probable alcoholics. The discrepancy between primary care physician's judgments and the SMAST and CAGE may be attributable to the doctor's failure to identify patients with alcohol-related problems. An alternative explanation is that the SMAST and CAGE are inappropriate screening tools for use in Australian primary care. The findings are discussed in terms of the implications for training doctors and for the development of better measures of alcohol-related problems for use within a primary care context.     

Teriparatide in the management of osteoporosis

Fracture of the hip is frequently a catastrophic event in the elderly, often resulting in death within a year and of the survivors, few regain pre-fracture quality of life. Although less appreciated, fractures of the spine result in significant morbidity and are also associated with increased mortality compared with individuals without a fracture. In recent years there has been an explosion in the development of new drugs for the treatment of osteoporosis. Recombinant human parathyroid hormone (1–34) (20 μg/day) is a recent addition to this armamentarium with a novel mechanism of action, which was approved by the US FDA for the treatment of post-menopausal osteoporosis and male osteoporosis secondary to hypogonadism in November 2002. It is the first osteoporosis treatment that leads to the formation of new bone with architecture similar to normal bone. Intense efforts have been made to understand the effect of teriparatide on antiresorptive therapy and vice versa. Although these relationships are not completely understood, the results of recent studies allow clinicians to begin to optimize therapeutic gains in bone mineral density and improve anti-fracture efficacy.     

Dose dependent effects of S-20098, a melatonin agonist,on direction of re-entrainment of rat circadian activity rhythms

The chronobiotic properties of melatonin are well documented. For example, following an 8-h phase advance of the light-dark cycle daily injections of melatonin administered at the pre-shift dark onset alter the direction of re-entrainment of rat activity rhythms. Using this 8-h phase advance paradigm, the effects of the melatonin agonist S-20098 (1 mg/kg and 3 mg/kg) on the rat circadian system were compared with those of melatonin. S-20098 altered the direction of reentrainment in the same manner as melatonin. A study using lower doses of S-20098 showed that the effect on direction of re-entrainment was dose-dependent, with 100% of rats responding at a dose of 100 µg/kg. S-20098 may, therefore, have therapeutic potential as a chronobiotic in the treatment of circadian disorders in humans.
