Abstract
Phenotypic expression of inflammatory cells in liver and hepatic lymph nodes (HLN) has been examined in lambs experimentally infected with Dicrocoelium dendriticum using immunohistochemical techniques. Thirty-two lambs, 12 infected with 1,000 D. dendriticum metacercariae, 12 with 3,000, and 8 controls were used. Half the lambs in each group were slaughtered on days 60 and 180 post-infection (p.i.), respectively. Primary antibodies (Abs) against T cell epitopes (CD3+, CD4+, CD8+ and WC1+ gammadelta), B cell epitopes (CD79alphacy+, CD45R+), immunoglobulin (IgG)-bearing plasma cells, macrophages (CD14+, VPM32+) and major histocompatibility complex (MHC) class IIbeta antigen were used. T lymphocytes (CD3+, CD4+ and CD8+) and B lymphocytes (CD79alphacy+ and CD45R+) with diffuse pattern or forming lymphoid aggregates and follicles surrounded the septal bile ducts (SBD) and inter-lobular bile ducts, whereas the WC1 gammadelta T cells were scattered. Numerous IgG+ plasma cells were observed around SBD. CD14 and VPM32+ macrophages intermingled with lymphocytes were immunostained by the anti-MHC class IIbeta. This Ab also reacted with lymphoid cells. Likewise, increased positive immunostaining for all Abs used was observed in the HLN of infected lambs. There was no qualitative difference regarding the phenotype expression of inflammatory cells between the lambs infected with D. dendriticum. The humoral and cell-mediated local immune responses observed were similar in the two groups of lambs infected with different doses.

Abstract
BACKGROUND Thiopurinic immunomodulators are effective for maintaining symptom remission in Crohn's disease. Little is known, however, about their effect on patients' quality of life or psychological well-being. The present study aimed to determine whether remission induced by thiopurinic immunomodulators returns levels of quality of life and psychological well-being to normal. MATERIALS AND METHODS A case-control study was performed. Cases were 33 patients with Crohn's disease treated with azathioprine or 6-mercaptopurine and in stable remission for at least 6 months. Sixty-six healthy individuals matched 2:1 by age and sex and 14 patients with active Crohn's disease were included as control groups. Quality of life was evaluated with the Short Form (SF-36) questionnaire, and the respective Hamilton rating scales were used for anxiety and depression. ANOVA with Bonferroni's correction was used for multiple comparisons. RESULTS SF-36 global scores were 85 in the study group, 85 in healthy controls (P = 1), and 58.6 in patients with active disease (P < 0.001 for the comparison with the other 2 groups). The differences between values were 0 (95% CI -4-4), 26.4 (95% CI 20-32), and 26.4 (95% CI 19-33), respectively. The respective anxiety and depression scores were 6.5, 5.5, and 16.2 and 3.7, 3.3, and 10.9. No significant differences were observed in any of the SF-36 domains between case and control groups, whereas in patients with active disease, all domains were significantly worse. CONCLUSIONS Thiopurinic immunomodulator-induced remission restores normal levels of quality of life and psychological well-being in Crohn's disease patients.

Abstract
Transvaginal laparoscopy (TvL) offers an alternative to standard diagnostic laparoscopy in subfertile patients without obvious pelvic pathology. With a specially developed needle-trocar system, access to the pouch of Douglas is gained through a needle puncture of the posterior fornix. Performed under local anaesthesia or sedation with the patient in a dorsal decubitus position and using prewarmed Ringer lactate as a distension medium, TvL allows complete exploration of the tubo-ovarian structures without supplementary manipulation. The combination of transvaginal sonography and transvaginal endoscopy, including minihysteroscopy, TvL, salpingoscopy and chromopertubation test, permits the most complete exploration of the reproductive tract and can be used as a first-line investigation of female fertility in a one-stop infertility clinic. As the transvaginal route offers easy access to the tubes, ovaries and fossa ovarica, some operative procedures are possible. However, in the absence of a panoramic view, these will be limited to minor interventions.

Abstract
In order to reduce the number of multiple pregnancies following IVF, the Belgian government agreed to reimburse laboratory expenses for six IVF cycles up to the age of 42 years, in exchange for restriction of the number of embryos replaced. Data on assisted reproduction outcome before and after the introduction of this new legislation were analysed retrospectively in terms of implantation, pregnancy and multiple pregnancy rates. After the introduction of the new law, the percentage of single embryo transfer increased from 14 to 49%. Implantation rates were 25.9 and 23% respectively. There was no difference in the overall pregnancy rate before and after the introduction (36 versus 37%). Twin pregnancies, however, decreased from 19 to 3%. These findings indicate that elective single embryo transfer significantly decreases the twin pregnancy rate without a reduction in the overall pregnancy rate.

Abstract
OBJECTIVES To determine the safety and effectiveness of a once-daily highly active antiretroviral therapy (HAART) regimen in patients at risk for poor adherence using directly observed therapy (DOT) for 24 weeks followed by weekly phone contact for another 24 weeks. METHODS A prospective, open-label pilot study was carried out. Antiretroviral-naïve patients with advanced HIV disease were treated with once-daily amprenavir 1200 mg, ritonavir 200 mg, didanosine 400 mg and lamivudine 300 mg. After 24 weeks, DOT was substituted by weekly phone contact. Measurements of viral load and CD4 cell count, and safety laboratory measurements, were taken regularly for 48 weeks. RESULTS Twenty-two patients were enrolled in the study, of whom 19 completed at least 4 weeks of treatment. Seventeen patients completed 24 weeks and 13 completed 48 weeks. None discontinued treatment as a result of adverse events. The median baseline HIV viral load was 5.29 log(10) HIV-1 RNA copies/mL and the median CD4 cell count was 20 cells/microL. At weeks 24 and 48, 74% of the patients had viral loads <400 copies/mL. At 48 weeks, the median decrease in viral load from baseline was 3.06 log(10) copies/mL, and the median increase in CD4 cell count was 118 cells/microL. The median trough plasma amprenavir concentrations at weeks 1 and 24 were 1.87 and 1.42 microg/mL, respectively. CONCLUSIONS This study suggests that DOT followed by weekly patient contact results in good treatment outcome in this challenging population. The median trough plasma amprenavir concentrations were above the effective concentration of drug that resulted in 90% inhibition of viral load in vivo (EC(90)) for wild-type HIV.

Abstract
BACKGROUND Outpatient management is safe for patients with non-variceal upper-GI bleeding who are at low risk of recurrent bleeding and death. However, outpatient care cannot be offered to many patients because of the presence of risk factors (severe comorbid disorders, major endoscopic stigmata of bleeding, significant hemorrhage). The present study assessed the safety of outpatient management for selected high-risk patients with bleeding peptic ulcer. METHODS Patients hospitalized with upper-GI bleeding because of peptic ulcer with a non-bleeding vessel were eligible for inclusion in the study. Inclusion criteria were the following: ulcer size less than 15 mm, absence of hypovolemia, no associated severe disease, and appropriate family support. After endoscopic therapy (injection of epinephrine and polidocanol), patients were randomized to outpatient or hospital care. Patients remained in the emergency ward for a minimum of 6 hours before discharge, during which time omeprazole was administered intravenously. Outpatients were contacted by telephone daily during the first 3 days; a 24-hour telephone hotline was provided for any queries. For both groups, outpatient visits were scheduled at 7 to 10 and 30 days after discharge. RESULTS A total of 82 patients were included: 40 were randomized to outpatient care and 42 to hospital care. Clinical and endoscopic variables were similar in both groups. The rate of recurrent bleeding was similar in both groups (4.8% outpatient, 5% hospital). There was no morbidity or mortality in either group at 30 days. Seven patients (17%) randomized to outpatient care received blood transfusion compared with 14 (38%) in the hospital care group (p=0.06). Mean cost of care per patient was significantly lower for the outpatient vs. the hospital group (970 US dollars vs. 1595 US dollars; p < 0.001). CONCLUSIONS Selected patients with bleeding peptic ulcer can be safely managed as outpatients after endoscopic therapy. This policy conserves health care resources without compromising standards of care.

Abstract
Hepatic enzymes and biochemical parameter values were analysed in the sera of 32 lambs: 12 infected with 1,000 Dicrocoelium dendriticum metacercariae, 12 with 3,000 and eight controls. Blood samples were collected at intervals of 30 days from day 0 post-infection (p.i.). Half the lambs in each group were slaughtered on days 60 and 180 p.i, respectively. A histopathological and ultrastructural study was carried out on the liver, gall bladder and hepatic lymph nodes of all animals. A minute increase was detected in the bilirubin (7%) and albumin (3%) values in the infected lambs (with 30-2,063 worms) in comparison with those of the controls. The hepatic enzyme values did increase, above all aspartate aminotransferase (19%) and alanine aminotransferase (22%), mainly in the lambs tested with 3,000 metacercariae (38% and 48%, respectively). The increase was significant 60 days p.i. The severity of the lesions was closely associated with the parasite burden.

Abstract
BACKGROUND & AIMS Endoscopic therapy reduces the rebleeding rate, the need for surgery, and the mortality in patients with peptic ulcer and active bleeding or visible vessel. Injection of epinephrine is the most popular therapeutic method. Guidelines disagree on the need for a second hemostatic procedure immediately after epinephrine; although it seems to reduce further bleeding, its effects on morbidity, surgery rates, and mortality remain unclear. The aim of this study was to perform a systematic review and meta-analysis to determine whether the addition of a second procedure improves hemostatic efficacy and/or patient outcomes after epinephrine injection. METHODS An extensive search for randomized trials comparing epinephrine alone vs. epinephrine plus a second method was performed in MEDLINE and EMBASE and in the abstracts of the AGA Congresses between 1990 and 2002. Selected articles were included in a meta-analysis. RESULTS Sixteen studies including 1673 patients met inclusion criteria. Adding a second procedure reduced the further bleeding rate from 18.4% to 10.6% (Peto odds ratio 0.53, 95% CI: 0.40-0.69) and emergency surgery from 11.3% to 7.6% (OR: 0.64, 95% CI: 0.46-0.90). Mortality fell from 5.1% to 2.6% (OR: 0.51, 95% CI: 0.31-0.84). Subanalysis showed that the risk of further bleeding decreased regardless of which second procedure was applied. In addition, the risk was reduced in all subgroups, although reduction was more evident in high-risk patients and when no scheduled follow-up endoscopies were performed. CONCLUSIONS Additional endoscopic treatment after epinephrine injection reduces further bleeding, need for surgery, and mortality in patients with bleeding peptic ulcer.

Abstract
INTRODUCTION The need for sedation is increasing in digestive endoscopy units (DEU). There are no data on the use of sedation in DEU in Catalonia (Spain). OBJECTIVE To evaluate the use of sedation in DEU in Catalonia. MATERIAL AND METHOD A questionnaire on the practice of sedation was designed and sent to the heads of medical and nursing staff of the DEU of 63 public and private hospitals in Catalonia. Two mailings were sent with an interval of three months between each. The questionnaire included 62 items on the characteristics of the hospital and the DEU, number of explorations, frequency of sedation use, drugs employed, participation of an anesthesiologist, use of monitoring, and complications. RESULTS Forty-four DEU (70%) corresponding to 31 public hospitals and 13 private hospitals completed the questionnaire. Evaluation of sedation patterns was based on 105,904 explorations performed in the various DEU (56,453 gastroscopies, 47,278 colonoscopies and 2,173 endoscopic retrograde cholangiopancreatographies (ERCP) in 2001. Sedation, sedation-analgesia or anesthesia was used in 17% of gastroscopies, 61% of colonoscopies and 100% of ERCP. Sedation was administered by an anesthesiologist in 7% of gastroscopies, 25% of colonoscopies and 38% of ERCP. Anesthesiologist administration was more frequent in private than in public centers (gastroscopies: 25% vs. 2%; colonoscopies: 57% vs. 9%, p < 0.001). No deaths associated with the use of sedation were reported. Eighty-nine percent of the DEU complied with standard recommendations for the practice of sedation. CONCLUSIONS In Catalonia, the use of sedation is highly variable, depending on the endoscopic procedure and the DEU. Use of sedation in infrequent in gastroscopy, fairly widespread in colonoscopy and routine in ERCP. Anesthesiologist administration is significantly more frequent in private hospitals. Most DEU follow standard sedation practices.

Abstract
BACKGROUND The optimal therapy for bleeding small bowel vascular lesions is controversial. This study investigated the efficacy and safety of endoscopic band ligation in this clinical condition. METHODS Fourteen patients bleeding from angiodysplasia and 4 bleeding from Dieulafoy's lesions located in the small bowel were included in this pilot study. Endoscopic band ligation was performed by using less than 200 mBar negative pressure in suctioning the target lesion into the ligation cap just before band release. Mean follow-up was 18 months (range 6-31 months). OBSERVATIONS Endoscopic band ligation achieved hemostasis in a single session in all patients. No adverse events occurred except for mild abdominal pain in two patients. Mortality was null, and no patient required further blood transfusion during the 40 days after endoscopic band ligation. No patient with Dieulafoy's lesion had further bleeding, whereas bleeding recurred in 6 of 14 (43%) patients with angiodysplasia during long-term follow-up. CONCLUSIONS Endoscopic band ligation is safe and effective for treatment of acutely bleeding small bowel vascular lesions. Although endoscopic band ligation is definitive therapy for Dieulafoy's lesion, long-term efficacy in the treatment of GI bleeding from angiodysplasia is limited.

Abstract
Endometriosis is a pleiotropic reproductive condition and the lesions visualized at laparoscopy are only one aspect of this disease process. At present, there is no evidence that surgery for endometriosis can cure infertility. The most important surgery in infertility is ovarian surgery. It is generally accepted that, in most cases, the invagination of the cortex results in the formation of an endometriotic pseudocyst. As a consequence, primordial follicles are present at the base of the cyst. Since surgery is of limited value, the utmost care has to be given to conservation of the patient's fertility. Ablative surgery offers advantages over excision of the cyst in terms of less adhesion formation and better preservation of the ovarian reserve. The ablative eversion technique differs from fenestration and drainage by its access through the site of inversion and resection of the fibrotic ring. Using the new technique of transvaginal hydrolaparoscopy, access to the site of pathology in the fossa ovarica is facilitated. Furthermore, the aqueous distension medium keeps the organs afloat and provides a clear delineation between the organs and adhesions allowing atraumatic reconstructive surgery.

Abstract
INTRODUCTION The use of a rapid diagnostic technique may be extremely useful for the management of Helicobacter pylori infection. A new immunochromatographic in-office test (ImmunoCard STAT! HpSA, Meridian Diagnosis Inc, Cincinnati, Ohio, USA) for the detection of H. pylori in feces has recently become available. The aim of the present study was to evaluate the diagnostic reliability and reproducibility of the ImmunoCard STAT! HpSA test in patients with dyspepsia. PATIENTS AND METHODS Sixty-three dyspeptic patients were enrolled. H. pylori status was determined by CLO-test and Giemsa staining of antral biopsy. Patients with a positive result for both tests were considered infected and those with a negative result for both tests were considered not infected. Fecal H. pylori antigen was tested twice by ImmunoCard STAT! HpSA. The sensitivity, specificity, positive predictive value and negative predictive value of each determination were calculated. The concordance between the two determinations was evaluated using Kappa statistics. RESULTS Of the 63 patients, 46 were infected by H. pylori. Sensitivity, specificity and positive and negative predictive values were 89-91%, 86-93%, 96-98% and 72-75%, respectively. The correlation coefficient between determinations was 0.845. CONCLUSION The new ImmunoCard STAT! HpSA test shows good sensitivity and reproducibility. Therefore, it could be highly useful in the management of H. pylori infection.

Abstract
BACKGROUND Helicobacter pylori-associated peptic ulcer is a frequent complication in cirrhotic patients and its morbidity rate is high. In spite of this, diagnostic methods for H. pylori infection have not been fully evaluated in these patients. AIM To evaluate H. pylori diagnostic methods in patients with liver cirrhosis. METHODS One hundred and one cirrhotic patients were included in the study. Three antral and two corpus biopsies were obtained for rapid urease test of the antral mucosa, and Giemsa stain and immunohistochemistry were performed for both the corpus and antrum. Serology, 13C-urea breath test and faecal H. pylori antigen determination were also carried out. RESULTS Sixty-two patients were positive and 35 were negative for H. pylori infection; four were indeterminate. The sensitivity and specificity were 90.4% and 100%, respectively, for antral histology, 100% and 100% for gastric body histology, 90.4% and 100% for antral immunohistochemistry, 96.2% and 96.7% for body immunochemistry, 85.7% and 97% for rapid urease test, 83.6% and 55.9% for serology, 96.4% and 97.1% for 13C-urea breath test and 75.4% and 94.1% for faecal antigen. CONCLUSION The most reliable tests for H. pylori infection in cirrhotic patients were the 13C-urea breath test and gastric body histology.

Abstract
An epidemiological study on dicrocoeliosis caused by Dicrocoelium dendriticum was carried out on sheep, molluscs and ants in the mountains of León province (NW Spain) between 1987-1991. The results concerning the intermediate hosts and a review of some aspects of dicrocoeliosis are summarized. Mollusc collection for the helminthological study was random throughout the study area at fortnightly intervals. Twenty-nine Gastropoda species were identified. D. dendriticum infection was only detected in 2.98%, of the 2084 Helicella itala examined and in 1.06% of 852 H. corderoi. The highest infection prevalence was detected in H. itala in September and in H. corderoi in February. Daughter sporocysts with well-developed cercariae predominated in spring and autumn. Infection prevalence increased with mollusc age and size. Ants were collected from anthills or plants to which they were attached. The behaviour of ants in tetania was followed. Twenty-one Formicidae species were identified, but only the following harboured D. dendriticum: Formica cunicularia (1158 examined specimens, 0.69% infection prevalence, 2-56 metacercariae per ant); F. sanguinea (234, 1.28%, 2-63); F. nigricans (1770, 4.97%, 1-186); F. rufibarbis (288, 6.59%, 2-107). In a flat area close to León town, 95.39% of the 2085 F. rufibarbis specimens collected in tetania contained metacercariae (1-240) in the abdomen. These were used for parasite characterization by isoelectric focusing and to infect lambs and hamsters. Only one brainworm per ant was found.

Abstract
BACKGROUND To date, the search for an in-office reliable test for Helicobacter pylori infection has been unsuccessful. The aim of the present study was to evaluate a new immunocromatographic in-office test using monoclonal antibodies to determine the presence of Helicobacter pylori antigen in faeces (Stick H. pyl, Operon S.A. Zaragoza). We compared its reliability and reproducibility to the currently available test (HpSA, EIA, Premier Platinum HpSA, Meridian Diagnosis Inc, Cincinnati, Ohio). PATIENTS AND METHOD 71 consecutive dyspeptic patients were enrolled. Helicobacter pylori status was determined by rapid urease test and Giemsa stain of antral biopsy. Patients with a positive result in the two tests were considered as infected and those with a negative result in both tests were regarded as not infected. Faecal Helicobacter pylori antigen was tested twice by means of HpSA. Four consecutive determinations of Stick H. pyl were also performed. We calculated sensitivity, specificity and positive and negative predictive values of each determination. Concordance between determinations was estimated by the kappa statistics. RESULTS Forty-eight of 68 patients were infected by Helicobacter pylori. Sensitivity, specificity and positive and negative predictive values were 89-96%, 60-70% 85-88% and 74-87%, respectively, for Stick H. pyl and 70-75%, 60-85%, 85-92% and 55-80%, respectively, for HpSA. Correlation coefficients were 0.82-0.93 for Stick H. pyl and 0.57 for HpSA. CONCLUSIONS The new Stick H. pyl test shows excellent sensitivity and reproducibility for diagnosis of H. pylori infection. Its reliability appears to be far better than that of HpSA.

Abstract
OBJECTIVE To determine the risk and outcome of bowel injury associated with new techniques of transvaginal pelvic endoscopy. DESIGN A multinational retrospective survey based on confidential, self-reported cases. SETTING Tertiary referral centers for infertility. PATIENT(S) Infertile patients without obvious pelvic pathology. INTERVENTION(S) Transvaginal hydrolaparoscopy and fertiloscopy. MAIN OUTCOME MEASURE(S) Full-thickness bowel injury. RESULT(S) Thirty-nine responders reported a total of 24 bowel injuries (0.65%) in 3667 procedures. After initial experience, the prevalence of bowel injury was 0.25%. All of the injuries were diagnosed during the procedure. Twenty-two (92%) of the cases were managed without consequences. CONCLUSION(S) The bowel lesion caused by the new techniques of transvaginal pelvic endoscopy tends to be minor and under strict conditions can be treated expectantly.
