Abstract
INTRODUCTION According to the estimates of the World Bank and the World Health Organization bipolar disorder is the sixth leading cause of handicap throughout the world. The burden of this disease is similar to the one of schizophrenia. But cost-of-illness studies are too seldom. Although preventive treatments of bipolar disorder are available for more than fifty years, their economic impact has rarely been studied. LITERATURE FINDINGS This review shows that the yearly cost of bipolar disorder is between 10,000 and 16,000 euro (12,000 and 18,000 US dollars). Eighty percent are indirect costs, 15% are linked to hospitalization and 5% to drugs. Hospitalization costs are lower in Health Maintenance Organization or general population studies than in studies performed on populations receiving care from psychiatric institutions or with a low socio-economic status. DISCUSSION The use of mood stabilizers has a substantial impact on direct costs which are halved and consequently on indirect costs. But different surveys all agree on the dramatic under-use of mood stabilizers which may be adequately prescribed to only a quarter of bipolar patients. CONCLUSION Therefore, the optimization of mental health system resources should prompt incentives to better screen, diagnose, and treat patients with a bipolar disorder.

Abstract
AIMS To determine the genetic relatedness of Campylobacter spp. from retail meat products, and compare the discriminatory power of pulsed-field gel electrophoresis (PFGE) and automatic ribotyping. METHODS AND RESULTS A total of 378 Campylobacter isolates recovered from 159 raw meats (130 chicken, 25 turkey, three pork and one beef) sampled from 50 retail grocery stores of four supermarket chains in the Maryland suburban area from August 1999 to July 2000 were analysed by PFGE with SmaI, 120 isolates of which were also characterized by ribotyping with PstI using RiboPrinter system. A total of 148 unique PFGE patterns were identified, 91 of which were present in multiple Campylobacter isolates and 24 in multiple meat samples. Nineteen Campylobacter clones with identical PFGE patterns recurred frequently (up to nine times) throughout the sampling period. Comparing ribotyping with PFGE, we identified 44 PFGE patterns and 22 RiboGroups among the 120 isolates tested. Multiple PFGE patterns within one RiboGroup were commonly observed, as well as multiple RiboGroups within one PFGE pattern. CONCLUSIONS Although Campylobacter present in retail meats were genetically diverse, certain clones persisted in poultry meats. PFGE had a greater discriminatory power than ribotyping, and the two methods were complementary in genotyping Campylobacter. SIGNIFICANCE AND IMPACT OF THE STUDY Genomic DNA fingerprinting of Campylobacter confirmed diverse and recurrent Campylobacter clones in the retail meats, which provides additional data for a better understanding of the epidemiological aspect of Campylobacter infection.

Abstract
BACKGROUND AND STUDY AIM Capsule endoscopy is a new tool in the evaluation of the small intestine. To speed evaluation and acceptance of this technology, the manufacturer (Given Imaging Ltd, Yoqneam, Israel) funded several trials. The data from these trials were collected at a central repository using a standardized reporting tool. Presentation of this data to the US Food and Drug Administration (FDA) in July 2003 led to the removal of the adjunctive term with regard to indication for capsule endoscopy, recognizing that the method is of independent importance for evaluating the small bowel. The aim of the present study was to combine the data from several capsule trials to help determine the yield and miss rate of capsule endoscopy for different diseases, compared with alternative diagnostic modalities. METHODS Capsule studies were identified from a master database of funded studies. Studies were included in the pooled analysis if they reported a prospective comparison with another modality for evaluation of the small intestine. RESULTS 32 studies with a total of 691 patients were found in the master database, of which 24 studies, representing 530 patients, met inclusion criteria and were entered into the pooled analysis. Prior to study entry, patients had undergone a mean of 6.77 diagnostic procedures, without findings. Of these 24 studies, 14 (involving 310 patients) were categorized as "bleeding" studies, and 10 studies (220 patients) as "nonbleeding small-bowel disorders" studies. The comparison procedure was push enteroscopy in 300 patients (in 45 for nonbleeding disorders), small-bowel series in 140 patients (in 125 for non-bleeding disorders), and colonoscopy with ileoscopy in 90 patients (50 for nonbleeding disorders). Overall analysis per patient showed new findings from capsule endoscopy in 50 % of patients; 17 % had new findings from the comparison method; in 22 % there were similar findings; and in 11 % there were no findings. A total of 1349 instances of disease were identified in the 530 examinations. Capsule endoscopy solely detected 87 % of the disease instances, while the comparison method solely detected 13 %. The yield for push enteroscopy alone was 14.8 %, for small-bowel series it was 9.9 %, and for colonoscopy it was 13.2 %. Capsule endoscopy missed 146 disease instances for a miss rate of 10 %; 989 were missed by the comparison methods for a miss rate of 73 %; and 214 were detected by both methods. CONCLUSION Capsule endoscopy is the state of the art method for noninvasive detection of small-bowel disease.

Abstract
BACKGROUND Assuming that psychomotor disturbances represent the core and are specific of melancholia, Parker et al. have developed the CORE, an 18-item scale assessing retardation, agitation and non-interactivity by behavioural observation which is able to distinguish melancholia from other depressive disorders. We report an inter-rater reliability study of the French version of the CORE. METHODS 35 French-speaking in-patients, with ICD-10 criteria for major depression underwent a video-recorded interview aimed to rate the CORE. Each patient's recording was rated by 5 psychiatrists. We tested the inter-rater reliability of the total CORE score and of each of its three subscales' scores using the intra-class correlation coefficient (ICC). A cut-off score for melancholia was established against the opinion of the psychiatrist in charge of the patient using a ROC curve. We used Cohen's kappa to assess the agreement between raters as to rate patients above the cut-off, namely the allocation of melancholia. RESULTS The global ICC for the total score was 0.88 and ranged from 0.97 to 0.75 for the varying rater dyads. A ROC curve yielded an optimal cut-off of 5 for melancholia. The global kappa for the agreement on melancholia allocation was good (0.65). LIMITATIONS The five raters had not exactly the same condition of quotation. The agreement for the "agitation" subscale was poor. CONCLUSION The French version of the CORE, has a good to excellent inter-rater reliability for the total score as for the allocation of melancholia according to a cut-off. Further validation studies are required to allow research application.

Abstract
BACKGROUND AND STUDY AIMS Capsule endoscopy (CE) is an effective means of investigating the small bowel in patients with gastrointestinal diseases. Computerized reports are frequently used in endoscopy, and the Minimal Standard Terminology (MST) has been promoted by endoscopy societies as the official vocabulary for endoscopy. The aims of this study were to design a lexicon for CE reports based on the principles of the MST and to validate lists of terms for describing findings and reasons for performing a CE by cross-matching them with the results of CE procedures collected during ongoing clinical studies. MATERIALS AND METHODS A consensus-based Capsule Endoscopy Structured Terminology (CEST) was developed by experts involved in CE studies. Lists of terms suitable for CE were designed for the various sections of an endoscopic report. They were then correlated with the corresponding MST lists for duodenal and intestinal endoscopy. The results of 766 CE procedures, collected in an electronic case record form (eCRF), were analyzed to provide lists of reasons for performing the procedures and of the findings. The eCRF provided only a limited number of items for each data field, along with free-text facilities. Only descriptions pertaining to the small bowel were analyzed. Lists of terms were then reviewed by two experts to group obvious synonyms. The accuracy of the CEST was defined beforehand as the capability to describe 90 % of entries. RESULTS A total of 766 CE procedures were analyzed. The eCRF included 824 entries as reasons for the examination in 655 CEs (1.3 per procedure). These represented 122 different expressions. After grouping of synonyms, 28 expressions remained. Among them, 10 were matched with terms from the list of reasons for performing CE offered in the CEST. These were the most frequently used, accounting for 768 entries in this field (93.2 %). All eCRFs contained at least one description of findings. A total of 109 CE procedures were classified as normal (14.3 %). A total of 2624 entries for abnormal findings were recorded for 657 procedures (4.0 per procedure). In all, 213 different expressions were used to describe abnormal findings. After grouping of synonyms, 52 expressions remained. Among these, 27 were matched with terms from the list of findings in the CEST, covering 2403 entries (91.6 %). CONCLUSIONS In this study, CEST terms were capable of describing more than 90 % of the reasons for performance and of the findings in an unselected set of CE procedures. CEST is therefore suitable for use as the standard lexicon for CE reports. Adopted as a standard, it could significantly improve the quality of the data collected and reported in CE studies.

Abstract
BACKGROUND Many non-responders to azathioprine or mercaptopurine (6-mercaptopurine) have high normal thiopurine methyltransferase activity and preferentially metabolize mercaptopurine to produce 6-methylmercaptopurine instead of the active 6-tioguanine (6-tioguanine) metabolites. AIM To describe the use of allopurinol in mercaptopurine/azathioprine non-responders to deliberately shunt metabolism of mercaptopurine towards 6-tioguanine. METHODS Fifteen thiopurine non-responders whose metabolites demonstrated preferential metabolism towards 6-methylmercaptopurine are described. Subjects were commenced on allopurinol 100 mg po daily and mercaptopurine/azathioprine was reduced to 25-50% of the original dose. Patients were followed clinically and with serial 6-tioguanine and 6-methylmercaptopurine metabolite measurements. RESULTS After initiating allopurinol, 6-tioguanine levels increased from a mean of 185.73 +/- 17.7 to 385.4 +/- 41.5 pmol/8 x 10(8) red blood cells (P < 0.001), while 6-methylmercaptopurine decreased from a mean of 10 380 +/- 1245 to 1732 +/- 502 pmol/8 x 10(8) RBCs (P < 0.001). Allopurinol led to a decrease in white blood cell from a mean of 8.28 +/- 0.95 to 6.1 +/- 0.82 x 10(8)/L (P = 0.01). CONCLUSIONS The addition of allopurinol to thiopurine non-responders with preferential shunting to 6-methylmercaptopurine metabolites appears to be an effective means to shift metabolism towards 6-tioguanine.

Abstract
CASE HISTORY An increase in the bulk somatic cell count (BSCC) of up to 1,000 x 103 cells/ml occurred in a dairy herd in Israel at the end of 2001 and beginning of 2002. CLINICAL FINDINGS Bacteriological examination of milk from 69 cows revealed a high prevalence of Streptococcus group G bacteria, identified as S. canis, affecting 38% of cows and 20% of all quarters. Isolates were sensitive to cephalothin and moderately sensitive to penicillin G. Infected cows were separated from the herd, treated with intramammary antibiotics, milked last, and strict hygiene practices were introduced to the milking routine. The pathogen was cleared from the herd and BSCC decreased to 250-350 x 103 cells/ml after 6 months. DIAGNOSIS Streptococcus canis mastitis. CLINICAL RELEVANCE Streptococcus canis infection may cause subclinical mastitis and high bulk SCC in dairy herds and be resolved by treatment with intramammary antibiotics and the introduction of strict hygiene practices.

Abstract
Thirty male adult Wistar rats (300-/+10 g body weight) underwent either 5/6 nephrectomy (Nx, n=20) or sham operation (SHAM, n=10) to determine olpadronate effects in an experimental model of uremic bone disease. For a 38-day period, 10 rats received olpadronate (16microg/100g bw) once a week (Nx+OPD) and the other vehicle (Nx). SHAM received vehicle. At baseline, treatment onset (t=7 days) and end of study (t=45 days) calcium, phosphorus, creatinine, bone alkaline phosphatase (b-ALP) and deoxypyridinoline crosslinks (DPyr) were determined. At t=0 and t=45 bone mineral density (BMD) was measured by DXA. At t=45 the right tibia was removed for bone histology. There were no differences in serum calcium. Phosphorus increased in Nx and Nx+OPD compared to SHAM (p<lt 0.05). The b-ALP increased from t=0 to t=7 in Nx and Nx+OPD (p<0.05) and decreased thereafter to SHAM levels. DPyr/creat increased in Nx compared to SHAM (p<0.05) and Nx+OPD (p<0.001). Nx+OPD presented lower DPyr excretion than SHAM rats (p<0.01). At t=45, tibia BMD of Nx was 20% and 26% lower than in SHAM (p<0.005) and Nx+OPD, respectively, (p<0.001). BMD was higher Nx+OPD than in SHAM (p<0.05). OPD prevented the loss of bone volume, the increment in osteoid volume and erosion surface observed in Nx group (p<0.05). OPD also prevent the increment in the number of osteoclasts (OC) and the active OC surface and decreases the number of TRAP(+)-OC (p<0.05). In summary, OLP may be beneficial in osteopenia associated to high turnover bone disease of CRF. However, the use of bisphosphonate therapy for renal insufficiency must be further investigated in order to clarify essential aspects of treatment as the patient selection and several aspects of treatment, such as optimum dose, frequency, and safe period of administration.

Abstract
Salmonella Typhimurium remains one of the most common causes of salmonellosis in animals and humans in the United States. The emergence of multi-drug resistant Salmonella reduces the therapeutic options in cases of invasive infections, and has been shown to be associated with an increased burden of illness. In this study, 588 S. Typhimurium (including var. Copenhagen) isolates obtained from either animal diagnostic specimens (n = 199) or food animals after slaughter/processing (n = 389) were examined for antimicrobial susceptibility, presence of class-1 integrons, and characterized using pulsed-field gel electrophoresis and phage typing. Seventy-six percent (448/588) of isolates were resistant to at least one antimicrobial. Salmonella isolates displayed resistance most often to streptomycin (63%), tetracycline (61%), ampicillin (61%), and to a lesser extent, chloramphenicol (36%), ceftiofur (15%), gentamicin (9%), and nalidixic acid (4%), with more resistance observed among diagnostic isolates. Salmonella recovered from turkeys (n = 38) exhibited the highest rates of resistance, with 92% of isolates resistant to least one antimicrobial, and 58% resistant to > or =10 antimicrobials. Class 1 integrons were present in 51% of all isolates. Five integron associated resistance genes (aadA, aadB, pse-1, oxa-2 and dhfr) were identified. A total of 311 PFGE patterns were generated using XbaI, indicating a genetically diverse population. The largest PFGE cluster contained 146 isolates, including DT104 isolates obtained from all seven animal species. Results demonstrated a varied spectrum of antimicrobial resistance, including several multidrug resistant clonal groups, among S. Typhimurium and S. Typhimurium var. Copenhagen isolates recovered from both diagnostic and slaughter/processing samples.

Abstract
AIM To determine the incidence, timing and clinical significance of acquired postnatal cytomegalovirus (CMV) in extremely low-birthweight (ELBW) infants. METHODS Prospective, longitudinal surveillance study. ELBW infants were recruited in the first week of life. Maternal blood was tested for CMV-specific IgG antibodies. Weekly urine samples were obtained from infants for CMV culture and rapid antigen testing. Data were collected regarding clinical course and breast milk intake. RESULTS Of 181 eligible infants, 119 infants, born to 101 mothers, were enrolled. Eighty of the 101 mothers had their serum checked for CMV status. Seventy percent of those tested were seropositive for CMV. Of the 65 infants born to seropositive mothers, 94% received breast milk during their hospital stay. Complete urine collection was obtained in 92 infants. CMV was cultured from the urine of only four infants, all of whom were born to seropositive mothers. Only one of these four infants was symptomatic. The range at which CMV was first detected was between 48 and 72 postnatal days of age. CONCLUSIONS Despite a very high CMV seropositivity rate in mothers of ELBW infants, and the previously reported high rate of CMV excretion into breast milk, the incidence of postnatal CMV transmission was extremely low in our study.

Abstract
INTRODUCTION The aim of this paper was to review and summarize the data about the frequency of depression during multiple sclerosis (MS). MATERIAL AND METHODS We performed a metaanalysis to combine the results of the studies which compared the frequency of depression in MS patients with the prevalence in patients with other chronic diseases. Eight controlled studies were identified via manual and computerized search of the Medline and PsychInfo databases. Given the various ways these studies reported their results, we used statistical procedures based on the combination of significance levels (the method of adding Zs and the method of adding ts). An additional statistical procedure, Cohen's d, was performed to estimate the effect of size. RESULTS The two statistical methods yielded highly significant summary statistics: z=4.15 and z=3.98, respectively (p<0.0001). The effect of size (Cohen's d), which ranged from 0.02 to 0.70 with an average of 0.29 (95 percent confidence interval: 0.09-0.49), can be considered as medium and hence clinically meaningful. CONCLUSION These results suggest that the association between MS and depression is specific, that is not just casual nor due to the nonspecific factors inherent in every chronic disease.

Abstract
BACKGROUND The interrelations between early enteral feeding, necrotising enterocolitis (NEC), and nosocomial sepsis (NS) remain unclear. OBJECTIVE To evaluate the effect of age at the introduction of enteral feeding on the incidence of NS and NEC in very low birthweight (VLBW< 1500 g) infants. METHODS Data were collected on the pattern of enteral feeding and perinatal and neonatal morbidity on all VLBW infants born in one centre during 1995-2001. Enteral feeding was compared between infants with and without NS and/or NEC. RESULTS The study sample included 385 infants. Of these, 163 (42%) developed NS and 35 (9%) developed NEC. Enteral feeding was started at a significantly earlier mean (SD) age in infants who did not develop nosocomial sepsis (2.8 (2.6) v 4.8 (3.7) days, p = 0.0001). Enteral feeding was introduced at the same age in babies who did or did not develop NEC (3.1 (2) v 3.7 (3) days, p = 0.28). Over the study period, the mean annual age at the start of enteral feeding fell consistently, and this correlated with the mean annual incidence of NS (r(2) = 0.891, p = 0.007). Multiple logistic regression analysis showed age at start of enteral feeding, respiratory distress syndrome, and birth weight to be the most significant predictors of risk of NS (p = 0.0005, p = 0.024, p = 0.011). CONCLUSIONS Early enteral feeding was associated with a reduced risk of NS but no change in the risk of NEC in VLBW infants. These findings support the use of early enteral feeding in this high risk population, but this needs to be confirmed in a large randomised controlled trial.

Abstract
OBJECTIVE To study the effect of prenatal consultation (PC) with a neonatologist on the incidence and duration of human milk feeding (HMF) in preterm infants. DESIGN/METHODS A retrospective matched case-control study was preformed at a perinatal centre. Study infants were preterm infants (23-35 wk) whose mothers had received PC emphasizing the importance of HMF. Control infants were matched by birthweight, gestational age and multiplicity. RESULTS Each group included 29 mothers and 46 preterm infants. Mean gestational age was 30.1 +/- 3 wk in both groups. Mean birthweight was 1329 +/- 489 (PC) and 1334 +/- 441 g (control). PC infants received HMF for significantly longer, both in the hospital and after discharge (hospital: PC 37 +/- 34 d vs control 15 +/- 19 d, p = 0.001; discharge PC 60 +/- 57 d vs control 21 +/- 32 d; p = 0.0001). No significant difference in neonatal morbidity was detected between the groups. CONCLUSIONS PC is associated with significantly longer HMF in preterm infants, both in hospital and after discharge.

Abstract
Salmonella enterica serotype Newport isolates resistant to at least nine antimicrobials (including extended-spectrum cephalosporins), known as serotype Newport MDR-AmpC isolates, have been rapidly emerging as pathogens in both animals and humans throughout the United States. Resistance to extended-spectrum cephalosporins is associated with clinical failures, including death, in patients with systemic infections. In this study, 87 Salmonella serotype Newport strains were characterized by pulsed-field gel electrophoresis (PFGE) and antimicrobial susceptibility testing and examined for the presence of class 1 integrons and bla(CMY) genes. Thirty-five PFGE patterns were observed with XbaI, and three of these patterns were indistinguishable among isolates from humans and animals. Fifty-three (60%) Salmonella serotype Newport isolates were identified as serotype Newport MDR-AmpC, including 16 (53%) of 30 human isolates, 27 (93%) of 29 cattle isolates, 7 (70%) of 10 swine isolates, and 3 (30%) of 10 chicken isolates. However, 28 (32%) Salmonella serotype Newport isolates were susceptible to all 16 antimicrobials tested. The bla(CMY) gene was present in all serotype Newport MDR-AmpC isolates. Furthermore, the plasmid-mediated bla(CMY) gene was transferable via conjugation to an Escherichia coli strain. The transconjugant showed the MDR-AmpC resistance profile. Thirty-five (40%) of the isolates possessed class 1 integrons. Sequence analyses of the integrons showed that they contained aadA, which confers resistance to streptomycin, or aadA and dhfr, which confer resistance to trimethoprim-sulfamethoxazole. One integron from a swine isolate contained the sat-1 gene, which encodes resistance to streptothricin, an antimicrobial agent that has never been approved for use in the United States. In conclusion, Salmonella serotype Newport MDR-AmpC was commonly identified among Salmonella serotype Newport isolates recovered from humans and food animals. These findings support the possibility of transmission of this organism to humans through the food chain.
