Validation and reproducibility of a semi-quantitative Food Frequency Questionnaire for use in elderly Swiss women.

OBJECTIVE: The principal aim of this study was to develop a Swiss Food Frequency Questionnaire (FFQ) for the elderly population for use in a study to investigate the influence of nutritional factors on bone health. The secondary aim was to assess its validity and both short-term and long-term reproducibility. DESIGN: A 4-day weighed record (4 d WR) was applied to 51 randomly selected women of a mean age of 80.3 years. Subsequently, a detailed FFQ was developed, cross-validated against a further 44 4-d WR, and the short- (1 month, n = 15) and long-term (12 months, n = 14) reproducibility examined. SETTING: French speaking part of Switzerland. SUBJECTS: The subjects were randomly selected women recruited from the Swiss Evaluation of the Methods of Measurement of Osteoporotic Fracture cohort study. RESULTS: Mean energy intakes by 4-d WR and FFQ showed no significant difference [1564.9 kcal (SD 351.1); 1641.3 kcal (SD 523.2) respectively]. Mean crude nutrient intakes were also similar (with nonsignifcant P-values examining the differences in intake) and ranged from 0.13 (potassium) to 0.48 (magnesium). Similar results were found in the reproducibility studies. CONCLUSION: These findings provide evidence that this FFQ adequately estimates nutrient intakes and can be used to rank individuals within distributions of intake in specific populations.

The influence of sentinel lymph node tumour burden on additional lymph node involvement and disease-free survival in cutaneous melanoma: a retrospective analysis of 392 cases

Twenty per cent of sentinel lymph node (SLN)-positive melanoma patients have positive non-SLN lymph nodes in completion lymph node dissection (CLND). We investigated SLN tumour load, non-sentinel positivity and disease-free survival (DFS) to assess whether certain patients could be spared CLND. Sentinel lymph node biopsy was performed on 392 patients between 1999 and 2005. Median observation period was 38.8 months. Sentinel lymph node tumour load did not predict non-SLN positivity: 30.8% of patients with SLN macrometastases (> or =2 mm) and 16.4% with micrometastases (< or =2 mm) had non-SLN positivity (P=0.09). Tumour recurrences after positive SLNs were more than twice as frequent for SLN macrometastases (51.3%) than for micrometastases (24.6%) (P=0.005). For patients with SLN micrometastases, the DFS analysis was worse (P=0.003) when comparing those with positive non-SLNs (60% recurrences) to those without (17.6% recurrences). This difference did not translate into significant differences in DFS: patients with SLN micrometastasis, either with (P=0.022) or without additional positive non-SLNs (P<0.0001), fared worse than patients with tumour-free SLNs. The 2-mm cutoff for SLN tumour load accurately predicts differences in DFS. Non-SLN positivity in CLND, however, cannot be predicted. Therefore, contrary to other studies, no recommendations concerning discontinuation of CLND based on SLN tumour load can be deduced.

Urological complications in renal transplantation from cadaveric donor grafts : a retrospective analysis of 20 years

Résumé : Introduction Cette étude est une analyse rétrospective des complications urétérales et de leurs prises en charge à partir d'une série monocentrique de 277 transplantations rénales consécutives. Matériel et méthode De septembre 1979 à juin 1999, 277 transplantations rénales (origine cadavérique) ont été pratiquées chez 241 patients. L'uretère provenant de la greffe rénale a été inséré dans la vessie selon la technique d'implantation extravésicale décrite par Lich-Gregoir et Campos-Freire. L'étude a analysé la date de survenue et le genre de complications observés. Les différentes procédures pour restaurer le tractus urinaire transplanté sont présentées dans cette étude. Résultats Des complications sont survenues chez 43/277 transplantations rénales (15,5%). Les fuites urinaires sur l'anastomose ou les sténoses urétérales étaient les plus fréquentes. La date de survenue de ces complications étaient soit précoce (< 1 mois) soit tardive (> 1 mois) dans un nombre similaire de cas. La plupart des cas ont été pris en charge chirurgicalement 33/43 cas (76,7%). La réparation chirurgicale la plus fréquente a été la réimplantation urétérovésicale (n-13), suivie par : l'anastomose urétérourétérale termino-terminale (uretère natif-uretère greffé, n-5) ; l'anastomose pyélourétérale (uretère natif-bassinet rénal greffé, n=5) ; la simple révision de l'implantation urétérovésicale (n=4) ; la résection et l'anastomose termino-terminale de l'uretère greffé (n=2) ; la calico-vésicostomie (vessie greffée, n=1) ; l'implantation selon Boari (n=1) ; la pyélovésicostomie avec bipartition de la vessie (n-1), et la pyéloiléocystoplastie avec greffe iléale détubularisée (n=1). Aucun décès en relation avec les complications urologiques n'a été rapporté. Cependant, 2 reflux vésico-rénaux consécutifs ont conduit à distance à la perte du greffon. Conclusion Le taux de complications constaté dans cette analyse rétrospective est similaire à celui observé dans d'autres études. Il se situe entre 2 et 20%. Si l'implantation urétérovésicale extravésicale classique reste une technique attractive en raison de sa simplicité, l'équipe chirurgicale dans un centre de formation doit rester attentive à toute mesure de prévention des complications urétérales, comme le choix d'une autre technique d'implantation de l'uretère et/ou de l'insertion transitoire d'un stent urétéral. Abstract Introduction: This study is a retrospective analysis of ureteral complications and their management from a monocenter series of 277 consecutive renal transplantations. Materials and Methods: From September 1979 to June 1999, 277 renal transplantations (cadaveric origin) were performed in 241 patients. The ureter from the kidney graft was inserted into the bladder according to the technique of extravesical implantation described by Lich-Gregoir and Campos-Freire. The study analyzed the time of occurrence and the type of complications observed. The different procedures to restore the transplanted urinary tract are presented. Results: Complications occurred in 431277 renal transplantations (15.5%). Anastomotic urine leakage or ureteral stricture were the most frequent. The time to appearance of these complications was either short (<1 month) or late (>1 month) in a similar number of cases. Most cases were managed surgically: 33/43 cases (76.7%). The most frequent surgi cal repair was ureterovesical reimplantation n =13), Followed by: ureteroureteral end, to end anastomosis (native ureter-ureter transplant, n =, 5); pyeloureteral anastomosis (native ureter-renal pelvis transplant n = 5): simple revision of ureterovesical implantation (n=4): resection and end-to end anastomosis of the transplant ureter (n=2); calico-vesicostomy graft-bladder, n = 1); implantation according to Boari (n= 1); pyelovesicostomy with bipartition of bladder (n = 1), and pyeloileocystoplasty with detubularized ileal graft (n=1). No deaths related to any of the urological complications were reported However, 2 consecutive vesico-renal refluxes led to the loss of the kidney graft in the long-term. Conclusion: The rate of complications observed in this retrospective analysis is similar to the experience of other studies, ranging from 2 to 20% If the classical extravesical ureteral bladder implantation is to remain an attractive technique due to its simplicity, the surgical team at the training center should be aware of all the means to prevent any ureteral complications, such as the choice of another implantation technique and/or insertion of a transient ureteral stent.

Validation statistique et structurale du questionnaire analytique de diagnostic de la personnalité (Q.A.P.)

The French Analytical Questionnaire of diagnostic of the Personality (Q.A.P., 1996), who took over from the characterological questionnaire of Berger (1950), is a interesting one for psychologists and characterologists because this test is based on very coherent theoretical corpus. This questionnaire is divided in two parts, the first one consists of three factor or fundamental scales which allow to determine the characterological type of individuals, the second part is made of nine complementary scales allowing to determine more precisely the personality of the subjects. We have done a structural validation of that questionnaire using a large sample (n=865). Several factor analyses were conducted on both part of the test. We also made a reliability analysis of each scale using the alpha of Cronbach and a homogeneity analysis of each question. Thank to these analyses we were able to evalue that instrument and we were able to set up that the factorial structure of the test corresponds to the theoretical one developped by the french school of characterology. The Analytical Questionnaire of diagnostic of the Personnality is globaly reliable in particullary the fist part which is very consistent. The second part is less reliable, and this is partly on due to the correlations between the scales. We have also done a correlational analysis between the first part of the Q.A.P., the questionnaire of Berger and the Rapid Questionnaire of Diagnostic of the Personnality (Q.R.D.P., 1996). The Q.A.P. might be the more reliable one. Finally we have evaluated the impact of gender, age and profession on the factors of the Analytical Questionnaire of diagnostic of the Personnality.

After-hours paediatric telephone triage and advice : the Neuchâtel experience

Résumé Introduction : Plusieurs études américaines et australiennes ont décrit des systèmes de tri téléphonique des urgences pédiatriques. En Europe, les services publics d'urgences pédiatriques ont peu de données épidémiologiques sur lesquelles s'appuyer pour répondre à la demande de soins. Depuis 1996, le département de pédiatrie de l'hôpital Pourtalès, Neuchâtel, offre, en dehors des heures ouvrables, mi tri téléphonique infirmier gratuit. Le présent travail analyse : 1) la situation suisse de l'offre en tri téléphonique infirmier pour les urgences pédiatriques ; 2) une partie des données épidémiologiques de l'expérience neuchâteloise. Méthode : 1) Un questionnaire a été envoyé aux 35 services d'urgences pédiatriques publics de Suisse pour Savoir si un tel tri était utilisé ; 2) une analyse rétrospective de tous les appels reçus, consignés sur fiches standardisées, en 1997 et 2000 a été menée. Résultats : 1) La majorité des services (27/35) ont effectivement un système de tri infirmier. Peu offrent une formation spécifique pour ce travail (14/27) ; 2) Au total, 7870 appels ont été analysés (3242 en 1997; 4628 en 2000, ± 43%). En semaine, la majorité ont été reçus entre 18h et 23h et le week-end en milieu de matinée. Septante-cinq % des appels ont concerné des enfants de 5 ans ou moins. La fièvre, les otalgies et la toux ont représenté 42% des plaintes. Vingt-sept % des appels ont été pris en charge uniquement par les conseils infirmiers, 15 % ont été transmis à l'interne de garde et 50% ont conduit à un rendez-vous dans le service le jour même. Conclusion : Nos données peuvent aider d'autres services d'urgences pédiatriques à planifier au mieux la mise en place d'un tel système de tri téléphonique. Abstract Delivery of paediatric primary care by call centres has emerged as a satisfactory system. It been reported in the literature in the United States and Australia. European public-funded paediatric emergency departments (ED) have little epidemiological data to rely on to match the demand in care. Since 1996, we have run a free nurse-led after-hours paediatric telephone triage and advice (TTA) system, To determine wether other Swiss public paediatric departments practiced formal TTA, we conducted a nation-wide postal survey. To delineate who used our call centre and for what reasons, we embarked on a retrospective study of ail the 1997/2000 calls. Most of the units run a TTA (27/35) but few specifically train their staff (14/27). A 43% increase in call numbers was seen between 1997 (3242) and 2000 (4628). During week-days, most of the calls were between 6 and 11 pm and at weekends, a mid morning activity peak was seen. Some 75% of calls were for children aged 5 years or less. Fever, earache and cough accounted for 42% of the main complaints. Of all calls, 27% were dealt by nurses' advice only. About 15% of the calls were transferred to the on-call resident. About 50% led to a same day ED appointment. Conclusion: Nurse-led paediatric telephone triage and advice is common in Switzerland where training seems to be irregular. Our data can help units to better plan an eventual paediatric telephone triage and advice service. After-hours; Paediatric; Telephone advice; Telephone triage

Bladder cancer documentation of causes: multilingual questionnaire, 'bladder cancer doc'

There is a considerable discrepancy between the number of identified occupational-related bladder cancer cases and the estimated numbers particularly in emerging nations or less developed countries where suitable approaches are less or even not known. Thus, within a project of the World Health Organisation Collaborating Centres in Occupational Health, a questionnaire of the Dortmund group, applied in different studies, was translated into more than 30 languages (Afrikaans, Arabic, Bengali, Chinese, Czech, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Kazakh, Kirghiz, Korean, Latvian, Malay, Persian (Farsi), Polish, Portuguese, Portuguese/Brazilian, Romanian, Russian, Serbo-Croatian, Slovak, Spanish, Spanish/Mexican, Tamil, Telugu, Thai, Turkish, Urdu, Vietnamese). The bipartite questionnaire asks for relevant medical information in the physician's part and for the occupational history since leaving school in the patient's part. Furthermore, this questionnaire is asking for intensity and frequency of certain occupational and non-occupational risk factors. The literature regarding occupations like painter, hairdresser or miner and exposures like carcinogenic aromatic amines, azo dyes, or combustion products is highlighted. The questionnaire is available on www.ifado.de/BladderCancerDoc.

Eating habits of preschool children with high migrant status in Switzerland according to a new food frequency questionnaire.

Assessment of eating habits in young children from multicultural backgrounds has seldom been conducted. Our objectives were to study the reproducibility and the results of a food frequency questionnaire (FFQ) developed to assess changes in eating habits of preschool children with a high migrant population, in the context of a multidisciplinary multilevel lifestyle intervention. Three kindergarten classes (53% from migrant backgrounds) in French-speaking Switzerland were randomly selected and included 16 girls and 28 boys (mean age +/- SD, 5.4 +/- 0.7 years). The FFQ was filled out twice within a 4-week interval by the parents. Spearman rank correlations between the first and the second FFQ for the 39 items of the food questions were as follows: low (r < 0.50) for 8 (7 P < .05 and 1 nonsignificant), moderate (0.50 <or= r < 0.70) for 22 (all P < .01), and high (r >or= 0.70) for 9 (all P < .01). In addition, 28 of 39 intraclass correlation coefficients were high (>0.50, all P < .01). Eighty-six percent of the children ate breakfast at home daily, but only 67% had lunch at home. The percentages of children eating at least once a week in front of the TV were as follows: 50% for breakfast, 33% for lunch, 38% for dinner, and 48% for snacks. Forty percent of children asked their parents to buy food previously seen in advertisements and ate fast food between once a week and once a month. Children generally consumed foods with a high-energy content. The FFQ yielded good test-retest reproducibility for most items of the food questions and gave relevant findings about the eating habits of preschool children in areas with a high migrant population.

Adolescents health in Georgia: a national portrait.

The aim of the study was to assess the basic indicators of health of adolescents in Georgia. A self-administered anonymous questionnaire was adapted from the Swiss Survey (SMASH2002), translated into Georgian and other languages mainly used in schools (Russian, Armenian and Azeri). It contained 87 questions. Two-stage cluster sampling was devised. Weight was adjusted. A total of 599 classes were selected. All questionnaires before being processed into the Epidata (www.epidata.dk) were edited. The final data were analysed by SPSS 11.0. General health status was considered as excellent and very good by 34.0+/-0.8% of respondents. 21.5% claimed to never miss the school due to the illness. The frequencies of physical disability and chronic diseases were 8.0% and 5.0% correspondingly. Among health-related problems the most frequent are problems with teeth, headache and acne. 5.9% of girls had some kind of gynecological problems quite often and very often. Performed survey is a first one done among adolescents in Georgia. It gave us basic information for planning and implementation of necessary measures in order to improve the health of adolescents and raise awareness of professionals involved in health care and prevention settings for adolescents. The data can be also used for monitoring of health status of adolescents in Georgia.

Peritalar dislocations: a retrospective study of 18 cases.

The purpose of this study is to retrospectively evaluate 18 consecutive cases of peritalar dislocations referred to our department during a period of 25 years and to delineate the factors influencing long-term prognosis. There were 13 (73%) medial and 5 (27%) lateral dislocations. Six patients (33%) suffered an open injury, including 2 of 13 (15%) medial and 4 of 5 (80%) lateral dislocations. Associated fractures involving the hindfoot or forefoot were noted in 7 feet, including 3 of 5 lateral dislocation cases. Reduction was accomplished under general anesthesia; in no case was open reduction necessary. In 4 of 6 open injuries with associated fractures, temporary fixation with Kirschner wires was performed. Patients were immobilized in a plaster cast for 4 weeks, or for 6 weeks in the presence of fracture, followed by weightbearing as tolerated. At a mean follow-up of 10.2 years (range, 4 to 26 years), 10 patients (56%) showed excellent results; all had sustained a closed medial low-energy dislocation. There were 3 cases (17%) with fair results and 5 cases (28%) with poor results. Forty-five percent of patients showed a restriction of activity, a reduction of subtalar range of motion, and moderate or severe radiographic signs of hindfoot degenerative arthritis. There were no cases of talar avascular necrosis, and in no case was secondary surgery necessary. Lateral dislocation and open medial dislocations with concomitant fractures showed a greater potential for poor prognosis. The results were independent from period of cast immobilization, suggesting that 4 to 6 weeks of immobilization provides acceptable long-term results.

Undertreatment of acute pain (oligoanalgesia) and medical practice variation in prehospital analgesia of adult trauma patients: a 10 yr retrospective study.

BACKGROUND: Prehospital oligoanalgesia is prevalent among trauma victims, even when the emergency medical services team includes a physician. We investigated if not only patients' characteristics but physicians' practice variations contributed to prehospital oligoanalgesia. METHODS: Patient records of conscious adult trauma victims transported by our air rescue helicopter service over 10 yr were reviewed retrospectively. Oligoanalgesia was defined as a numeric rating scale (NRS) >3 at hospital admission. Multilevel logistic regression analysis was used to predict oligoanalgesia, accounting first for patient case-mix, and then physician-level clustering. The intraclass correlation was expressed as the median odds ratio (MOR). RESULTS: A total of 1202 patients and 77 physicians were included in the study. NRS at the scene was 6.9 (1.9). The prevalence of oligoanalgesia was 43%. Physicians had a median of 5.7 yr (inter-quartile range: 4.2-7.5) of post-graduate training and 27% were female. In our multilevel analysis, significant predictors of oligoanalgesia were: no analgesia [odds ratio (OR) 8.8], National Advisory Committee for Aeronautics V on site (OR 4.4), NRS on site (OR 1.5 per additional NRS unit >4), female physician (OR 2.0), and years of post-graduate experience [>4.0 to ≤5.0 (OR 1.3), >3.0 to ≤4.0 (OR 1.6), >2.0 to ≤3.0 (OR 2.6), and ≤2.0 yr (OR 16.7)]. The MOR was 2.6, and was statistically significant. CONCLUSIONS: Physicians' practice variations contributed to oligoanalgesia, a factor often overlooked in analyses of prehospital pain management. Further exploration of the sources of these variations may provide innovative targets for quality improvement programmes to achieve consistent pain relief for trauma victims.

Better 6 months outcome for steroid refractory ulcerative colitis with infliximab rescue therapy compared to tacrolimus or cyclosporine: a Swiss IBD cohort retrospective analysis

BACKGROUND: C iclosporine ( CsA), Tacrolimus (Tcl) and Infliximab (IFX) are effective rescue therapies in steroidrefractory ulcerative colitis (UC). Comparative studies are however m issing. M ETHOD: T his i s the retrospective analysis of treatment outcome for oral Tcl (n=27, initially 0.05mg/Kg twice daily, aiming for serum trough levels of 5-10 n g/mL), i ntravenous C sA ( n=23, 2 mg/kg/daily a nd then o ral CsA 5mg/kg/daily) and IFX ( n=43, 5 mg/kg intravenously at week 0, 2, 6 and then every 8 weeks) in patients with s teroid r efractory moderate to s evere UC enrolled i n the SWISS IBD cohort s tudy. After successful rescue therapy with Tcl o r C sA, t hiopurine m aintenance therapy or maintenance therapy with Tcl (in Tcl pretreated patients) was introduced. The endpoints analyzed steroid free r emission r ate (on the basis of m odified Truelove- Witts severity index (MTWSI)) and number of colectomies after 6 m onths. R ESULTS: A t 6 months, 26% ( 7/27) o f patients treated with T cl r emained i n steroid free remission (MTWSI score ≤4) compared to 30 % (7/23) on 18 droplets to the same extend under the linoleic acid treat, whereas lipid hydrolysis or loss was significantly increased in Huh-7 WT cells after 24h. Conclusions: Chronic alcohol feeding in obese, insulin-resistant rats exerts significant and synergistic effects on PNPLA3 mRNA expression, which correlated with triglyceride content. In v itro experiments suggest that PNPLA3 expression depends on the t ypes of d ietary f atty acids with polyunsaturated fatty a cids i nducing a nd monounsaturated fatty a cids inhibiting PNPLA3 mRNA.
