Cost comparison of axillary sentinel lymph node detection and axillary lymphadenectomy in early breast cancer. A national study based on a prospective multi-institutional series of 985 patients 'on behalf of the Group of Surgeons from the French Unicancer Federation'.

BACKGROUND: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients. PATIENTS AND METHODS: We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery. RESULTS: Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€ 2947 (σ = 580) versus € 3331 (σ = 902); P = 0.0001]. CONCLUSION: ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

[Comparison of two routine screening strategies for gestational diabetes mellitus: the experience of Jean-Verdier Hospital]. / Comparaison de deux politiques de dépistage du diabète gestationnel: expérience de l'hôpital Jean-Verdier.

OBJECTIVE: Screening strategies for gestational diabetes mellitus are controversial. Thus, we sought to determine the benefits of universal screening. PATIENTS AND METHODS: Prospective study with 2121 women involved but 1610 really screened (75.9%). According to WHO's recommendations, the strategy implemented was one-step, universal screening with a 75g oral glucose tolerance test. Screening was performed between 24 and 28 weeks of gestation or earlier if risk factors were identified. Results were compared to previous year (2001) then only a selective screening was done. RESULTS: Application of universal screening increased the prevalence of gestational diabetes mellitus (8.39% to 15.65%). Out of the 252 patients with gestational diabetes, 66 did not display any identified risk factor (26.19%). Some new risk factors have been identified: age>30, Asian, Indian or Pakistan ethnies. If these new risk factors were applied, this super selective screening would have a sensibility of 96%. DISCUSSION AND CONCLUSION: Universal screening seems to be the most appropriate routine screening strategy because it is difficult to know exactly the specific risk factors of a population to do a super selective screening.

Ultrasonographic assessment of inflammatory bowel disease in children: comparison with ileocolonoscopy.

OBJECTIVES: To determine the feasibility and value of transabdominal ultrasonography of the terminal ileum and colon of children with inflammatory bowel disease (IBD) and to compare the findings with those of ileocolonoscopy. STUDY DESIGN: Thirty-eight patients ranging in age from 4 to 18 years who underwent ileocolonoscopy for management of IBD or for diagnosis were studied prospectively. Twenty-one patients had Crohn disease, nine had ulcerative colitis, and eight served as control subjects. Transabdominal ultrasonography was performed on the day before ileocolonoscopy. Ultrasonographic findings were compared with the results of ileocolonoscopy, used as the reference method. RESULTS: Peristalsis was recorded in all segments of the control subjects; the thickness of the terminal ileum was always less than 2.5 mm, and that of the large bowel, 2 mm or less. In the two patient subgroups, the thickness range of affected ileal and colonic segments was similar, but values were significantly different from those of the control subjects (chi-square test, p <0.0001). The overall sensitivity of the method was 88%, and the specificity, 93%. CONCLUSION: Transabdominal ultrasonography should prove to be a useful clinical and investigational technique, although further studies are needed to assess its value in the treatment of children with IBD.

[Cost evaluation of therapeutic management of patients with chronic hepatitis C]. / Evaluation du coût de la prise en charge thérapeutique des patients porteurs d'une hépatite chronique C.

Hepatitis C now poses an important problem of public health in France. The objective of this study was to evaluate the cost of care of 55 patients who were carriers of hepatitis C and treated with interferon alpha. The economic analysis included the blood testing costs, pharmaceutical costs and hospitalization costs. A questionnaire permitted the impact of the treatment on the socio-professional life of each individual to be assessed. The global cost amounted to 1155 359 francs spread among hospitalization costs (55 pour cent), pharmaceutical costs (35.8 pour cent) and blood testing costs (9.2 pour cent). Of 36 actively working patients being treated, 10 modified their activities and 4 of these 10 restarted their initial activities after stopping treatment. This evaluation has shown the disparities which exist in the clinical follow up of patients treated for chronic hepatitis C. It is thus imperative to institute a systematic screening of patients being transfused to permit an early diagnosis, to establish a rigorous standardization of blood testing, to visualise day care treatment and above all to establish a consensus of global care of these patients.

Resting energy expenditure before and after surgical resection of gut lesions in pediatric Crohn's disease.

In pediatric Crohn's disease (CD), resection of gut lesions is necessary to remove stenoses and when frequent relapses occur despite nutritional support and medical treatment. After surgery, improved nutritional status and accelerated growth usually follow increased nutritional intake and lower doses of steroids. The aim of this study was to compare energy balance before and after surgery while nutritional intake and steroid therapy were unchanged. Eleven patients, aged 14.5 +/- 2.5 years and with mildly active CD, were explored 1 week before and 1 month after gut resection for stenosis (n = 7) and medical treatment failure (n = 4). Eleven matched children participated in the study as controls. Disease activity was assessed by the Pediatric Crohn's Disease Activity Index and serum orosomucoid concentration. Resting energy expenditure (REE) was measured by indirect calorimetry, and fat-free body mass (FFM) was measured by anthropometry. The patients' mean REE decreased from 46.6 +/- 10.5 kcal/kg FFM/day before surgery to 42.6 +/- 10.3 kcal/kg FFM/day after surgery, while the controls' mean REE was 39 +/- 7 kcal/kg FFM/day (analysis of variance, p = 0.02). After surgery, body weights were not significantly different, but the mean protein oxidation rate was reduced and arm muscle area was increased. Changes in REE per kilogram of FFM per day were not correlated with changes in orosomucoid serum concentrations (r2 = 0.35; p = 0.4). In conclusion, in children with mildly active CD, while nutritional intake and steroid therapy were maintained at preoperative levels, a significant decrease in REE and improved nitrogen utilisation were observed 1 month after resection of the CD gut lesion. This finding suggests better use of energy substrates when CD lesions are removed.

Cost-benefit evaluation of systematic radiological diagnosis of congenital dislocated hip.

The question of radiological mass screening for congenital dislocated hip is still debated. We have tried to evaluate the cost-benefit ratio of radiological detection at the age of 3-4 months, taking into account the socio-economic cost and radiation risk. Assuming a frequency of this disorder of 1% the average cost of treatment of one case detected by X-ray screening at the age of 3-4 months, including the price of X-ray examinations of 99 normal babies, is 23,374 FF. The average cost of treatment of a case detected when walking (i.e. after 9 months) is 84,230 FF. The cost-benefit ratio is 3.6. In countries where the frequency reaches 2% the cost benefit ratio is 4.57. It also appears from our study that the irradiation of the patient is much smaller when the diagnosis is made earlier. Comparing the slight irradiation delivered to normal infants by this mass screening to the heavy irradiation received by a few individuals whose treatment is started after 9 months, the calculated risk of leukemia or of genetic disorder for the whole population still favours a systematic X-ray film of the pelvis at age 3-4 months. However, if it were decided to make obligatory this mass radiological detection programme during the fourth month of life, this would necessitate a serious effort to train all radiologists to obtain adequate films with the best radiation protection.
