The effect of centralization of primary surgery on survival in ovarian cancer patients

OBJECTIVE: To examine the effect of centralized surgery on overall survival in patients with ovarian cancer and, in particular, patients with advanced disease (stage III/IV). METHODS: In a historical prospective study design, patients referred from community hospitals to a teaching hospital for primary surgery during the 2-year period, 1995-1997, were included as cases. For each referred case, two controls, matched for International Federation of Gynecology and Obstetrics (FIGO) stage and age, were selected among patients who had had primary surgery at the referral hospitals (nonteaching) in the years, 1992-1995. Kaplan-Meier survival curves were computed and tested statistically by the log rank test. Cox proportional hazard model was applied for estimation of prognostic factors of survival. RESULTS: There was no difference in postoperative mortality for stage I/II patients by level of care (community hospitals versus teaching hospital). However, for advanced stage disease (III + IV), the controls had significantly shorter crude survival than patients who had been operated on at the teaching hospital (5-year survival: 4% versus 26%; median survival: 12 months versus 21 months) (P=.01). Multivariable analyses showed that completed chemotherapy and size of residual tumor after primary surgery were independent prognostic factors of survival. Patients optimally operated on at the teaching hospital had significantly lower risk of death compared with all other groups, independently of chemotherapy. This indicates that the extent of cytoreductive surgery and the overall management undertaken in the teaching hospital are significant predictors of improved survival. CONCLUSION: Centralization of primary ovarian cancer surgery in one health region in Norway has improved survival for patients with advanced disease. Patients with apparent advanced ovarian cancer should be referred to a subspecialty unit for primary surgery, and every effort should be made to attain as complete cytoreduction as possible.     

The final phase in acute myeloid leukaemia (AML). A study on bleeding,infection and pain

To increase the knowledge of the final phase of acute myeloid leukaemia (AML) a retrospective review of the medical and nursing records of 106 adult patients with AML who had died in 1995-1997 was made. A total of 27 patients were treated with curative intent at the time of death and 79 patients were prescribed palliative care. From the documentation, an evaluation of the frequency and severity of bleeding and pain episodes was made during their last week in life, and the occurrence of infection criteria was studied. Notations on bleeding were found in 44%, infection in 71% and pain in 76% of the patients. In 54% of the morphine administration days, no information on the effect of given morphine treatment was registered. To give AML patients in the final phase, the best possible treatment, skills in palliative medicine and palliative care are important.     

Complications of vaginal myomectomy by posterior colpotomy

OBJECTIVE: To evaluate the morbidity of vaginal myomectomy by posterior colpotomy. STUDY DESIGN: From January 1, 1994, through December 31, 2003, 108 patients in our department underwent a vaginal myomectomy procedure by posterior colpotomy. This study assessed the intra-operative (conversion to laparotomy, organ injury, hemorrhage) and post-operative (hematoma, abscess) complications as well as the risk factors for conversion to laparotomy. RESULTS: There were 27 intra- or post-operative complications (25%), 17 (15.7%) of which concerned conversion to laparotomy necessary for successful myomectomy. One case involved rectal injury (0.9%), three hemorrhages (2.8%), one hematoma (0.9%) and five abscesses (4.7%). The mean weight of fibromas was significantly higher in the group of patients undergoing laparotomy (19 cases) than in the vaginal-myomectomy-only group (89 cases) (270+/-197 g versus 181+/-143 g, p=0.02). Similarly, the fibroma size measured by ultrasound was higher in the laparotomy group than in the vaginal-myomectomy-only group, but this difference was not significant (82.6+/-27.1 mm versus 73.7+/-21.8 mm, p=0.13). CONCLUSIONS: The principal risk of vaginal myomectomy is that it will require conversion to laparotomy. The risk of pelvic abscess also appears greater in myomectomy than in other procedures. However, apart from the risk of conversion to laparotomy, vaginal morbidity is lower with this procedure. Vaginal myomectomy is a useful alternative to laparotomy for specific indications.     

Decrease of some metabolic and physiologic effects of diazoxide by propranolol in rat

Summary Diazoxide significantly decreased the blood pressure and relaxed the uterine muscle in anaesthetized normotensive rats. A marked elevation of blood glucose followed the intravenous injection of diazoxide. The hyperglycemic and the uterine relaxing response could be significantly decreased by injection of propranolol prior to diazoxide. The hypotensive effect was not diminished by propranolol, however. In liver and uterus the content of cAMP was increased following diazoxide treatment in vivo. The rise in cAMP could be completely inhibited by propranolol, indicating a -receptor stimulation being the cause of the cAMP elevation.     

Fatigue interference with daily living among patients with inflammatory bowel disease

Purpose

The purpose of the study was to examine fatigue interference with daily living in patients with inflammatory bowel disease (IBD) and to explore relationships between severe fatigue interference and socio-demographic and clinical variables, including use of complementary and alternative medicine (CAM).

Methods

Data were collected using self-report questionnaires from adult IBD outpatients. Fatigue interference was assessed with the 5-item Fatigue Severity Scale, and scores ≥5 were defined as severe fatigue interference. CAM use was assessed with the International CAM Questionnaire. Multivariate logistic regression analysis was used to examine associations between severe fatigue interference and socio-demographic factors, clinical factors, and CAM use.

Results

In total, 428 patients had evaluable questionnaires (response rate 93 %). Severe fatigue interference was reported by 39 % of the total sample. Patients with Crohn’s disease (CD) (n = 238) were more likely than patients with ulcerative colitis (UC) (n = 190) to report severe fatigue interference (43 and 33 %, respectively, p = 0.003). In addition, patients reporting severe fatigue interference were more likely to have active disease than patients without severe fatigue interference (p < 0.001 for both diagnoses). Patients with inactive disease had scores comparable to the general population. Factors independently associated with severe fatigue interference in UC included disease activity and CAM use, while in CD they included disease activity and current smoking.

Conclusions

Severe fatigue interference is common among IBD patients with active disease. Among patients with UC, but not CD, CAM use was associated with severe fatigue interference. The relationship between fatigue interference and personal factors should be considered further in subsequent studies.     

Mammographic Density and Intake of Selected Nutrients and Vitamins in Norwegian Women

Investigating the association between dietary factors and mammographic density (MD) could shed light on the relationship between diet and breast cancer risk. We took advantage of a national mammographic screening program to study the association between intake of nutrients and MD. In this study, we analyzed data of 2,252 postmenopausal women aged 50–69 yr who participated in the Norwegian Breast Cancer Screening Program in 2004. MD was assessed on digitized mammograms using a computer-assisted method. We used multivariate linear regression models to determine least square means of percent and absolute MD. Overall, we observed no associations between MD and intake of total calories, protein, carbohydrates, cholesterol, and dietary fiber. There was a positive borderline statistically significant association between absolute MD and total fat intake (P = 0.10) and between percent MD and intake of saturated fat (P = 0.06). There was no association between MD and intake of calcium, retinol, vitamins A, B12, C, or D, or combined intake of vitamin D and calcium. This study provides some evidence of an association between MD and dietary intake. Our study highlights the importance of adequate adjustments for BMI in studies of diet and MD.     

Life satisfaction in early rheumatoid arthritis: A prospective study

The aim of this study was to describe life satisfaction prospectively in patients with early rheumatoid arthritis (RA) and to investigate its correlation with disease activity. The early RA group was compared with RA patients with longstanding disease and with a reference group. Gender differences were also compared. Patients with early RA, treated by a multidisciplinary team, reported their life satisfaction by completing a questionnaire. Disease activity score, patient global assessment, and pain were scored at onset of disease and after two years. The patients with early RA were less satisfied with life as a whole at disease onset compared with the reference group, as was a cohort of patients with longstanding disease. Patients with early RA also reported low levels of satisfaction with self-care activities, work, and sexual life. The women reported themselves more satisfied than men. After two years, a slight increase in the reported levels of satisfaction could be seen for life as a whole and for five of the eight domains. No correlation was found between disease activity variables and satisfaction with life as a whole. There were, however, positive correlations between disease activity and satisfaction both with partnership and with family life after two years, i.e. the higher disease activity the higher satisfaction with partnership relation and family life. In contrast, patients with greater disease activity were less satisfied with self-care activities. The results of this study indicate that greater effort is needed to assist patients with early RA to cope with problems concerning self-care activities, sexual life, and work.     

Inhalation Studies with the Göttingen Minipig

A method for inhalative exposure of minipigs to aerosols and gases has been developed. Minipigs are exposed via mask inhalation to the test substance using a computer-controlled exposure system that permits simultaneous exposure of groups of four animals in parallel to different controlled dose levels. We studied inhalation treatment of verapamil, a cardiovascular drug, and show good absorption and favorable pharmacokinetics when compared with iv drug application. The results shown in this study encourage inhalation studies with the Göttingen minipig.
