Long-term mortality and causes of death in endoscopically verified upper gastrointestinal bleeding: comparison of bleeding patients and population controls.

OBJECTIVE: Upper gastrointestinal bleeding (UGIB) is a common emergency, with in-hospital mortality between 3 and 14%. However, the long-term mortality and causes of death are unknown. We investigated the long-term mortality and causes of death in UGIB patients in a retrospective single-centre case-control study design. METHODS: A total of 569 consecutive patients, aged ≥18 years, admitted to Kuopio University Hospital for their first endoscopically verified UGIB during the years 2009-2011 were identified from hospital records. For each UGIB patient, an age, sex and hospital district matched control patient was identified from the Statistics Finland database. Data on endoscopy procedures, laboratory values, comorbidities and medication were obtained from patient records. Data on deaths and causes of death were obtained from Statistics Finland. RESULTS: In-hospital mortality of UGIB patients was low at 3.3%. The long-term (mean follow-up 32 months) mortality of UGIB patients was significantly higher than controls (34.1 versus 12.1%, p < .001). During the 6 months following UGIB, the risk of death compared to controls was highest (HR 19.2, 95% CI 7.0-52.4, p < .001) and remained higher up to 3 years after the bleeding. Beyond 3 years' follow-up, there was no difference in mortality between the groups (HR 0.7, 95% CI 0.4-1.6, p = .436). During the first 3 months after the UGIB episode, mortality was related to gastrointestinal diseases; after 3 months, the causes of death were related to comorbidities and did not differ from causes of death in controls. CONCLUSIONS: UGIB patients have three times higher long-term mortality than population controls.

Relationship between wild greylag and European domestic geese based on mitochondrial DNA.

The origins of the European domestic goose are uncertain. The available information comes from archaeological findings and historical literature, but genetic evidence has hitherto been scarce. The domestic goose in Europe is derived from the greylag goose (Anser anser), but it is not known where the initial domestication took place and which of the two subspecies of greylag goose was ancestral. We aimed to determine the amount and geographical distribution of genetic diversity in modern populations of greylag geese as well as in different breeds of the domestic goose to make inferences about goose domestication. We studied DNA sequence variation in the mitochondrial control region of greylag geese from multiple populations across Europe and western Asia as well as specimens of domestic geese representing 18 modern breeds and individuals not belonging to any recognised breed. Our results show notable differences in genetic diversity between different greylag goose populations and the presence of six mitochondrial haplogroups which show a degree of geographical partitioning. The genetic diversity of the domestic goose is low, with 84% of sampled individuals having one of two major closely related haplotypes, suggesting that modern European domestic geese may derive from a narrow genetic base. The site of domestication remains unresolved, but domestic geese in Turkey were unusually diverse, indicating the importance of further sampling in the vicinity of the eastern Mediterranean and the Near East. There appears to be past or ongoing hybridisation between greylags and domestic geese in particular areas, consistent with field observations.

Nonlocal quantum fluctuations and fermionic superfluidity in the imbalanced attractive Hubbard model.

We study fermionic superfluidity in strongly anisotropic optical lattices with attractive interactions utilizing the cluster dynamical mean-field theory method, and focusing in particular on the role of nonlocal quantum fluctuations. We show that nonlocal quantum fluctuations impact the BCS superfluid transition dramatically. Moreover, we show that exotic superfluid states with a delicate order parameter structure, such as the Fulde-Ferrell-Larkin-Ovchinnikov phase driven by spin population imbalance, can emerge even in the presence of such strong fluctuations.

Serum and CSF soluble CD26 and CD30 concentrations in healthy pediatric surgical outpatients.

Activated T-helper type 1 (Th1) lymphocytes induce a cellular type immune response, and Th2 lymphocytes, a humoral or antibody-mediated type immune response. Soluble CD26 (sCD26) and soluble CD30 (sCD30) are regarded as markers of Th1 and Th2 lymphocyte activation, respectively. Serum from 112 generally healthy pediatric surgical patients and cerebrospinal fluid (CSF) from 39, aged 1-17 years were measured for sCD26 and sCD30 using an enzyme-linked immunosorbent assay method. The detection limit for sCD26 was 6.8 ng/ml and for sCD30, 1.9 IU/ml. For serum sCD26 and sCD30, 2.5% and 97.5% percentiles constituted the reference limits, and the 95% credible intervals for the percentiles were calculated using regression models with a Bayesian approach. A significant between-gender difference was observed (P = 0.015) in serum sCD26 concentration, of which the lower limits ranged between 273 and 716 ng/ml for girls and 235 and 797 ng/ml for boys. The upper limits ranged between 1456 and 1898 ng/ml for girls and between 1419 and 1981 ng/ml for boys. Moreover, the concentrations of sCD26 increased in infants and children up to 10 years in girls and 12 years in boys. After this however, the values decreased. The serum sCD30 concentration was highest among the youngest infants aged 1 year (80-193 IU/ml), after which a consistent age-related decrease was found. The lowest values were found at the age of 17 years (10-89 IU/ml). A significant between-gender difference in sCD30 concentration was observed (P = 0.019). sCD26 and sCD30 concentrations were low in the CSF samples analyzed: 13.3 ng/ml (median); range 8.3-51.5 ng/ml and 7.6 IU/ml; 2.1-18.5 IU/ml, respectively. Reference limits for serum sCD26 in children aged 1-17 years were established as being 235-1800 ng/ml in toddlers and 400-1800 ng/ml in female adolescents and 700-2000 ng/ml in male adolescents. For sCD30; reference limits of 80-190 IU/ml were established in the youngest age group and 10-90 IU/ml in adolescents.

Extremely high prevalence of multidrug resistant tuberculosis in Murmansk, Russia: a population-based study.

Drug resistance and molecular epidemiology of tuberculosis (TB) in the Murmansk region was investigated in a 2-year, population-based surveillance of the civilian population. During 2003 and 2004, isolates from all culture-positive cases were collected (n = 1,226). Prevalence of multi-drug resistance (MDR) was extremely high, as 114 out of 439 new cases (26.0%), and 574 out of 787 previously treated cases (72.9%) were resistant to at least isoniazid (INH) and rifampin (RIF). Spoligotyping of the primary MDR-TB isolates revealed that most isolates grouped to the Beijing SIT1 genotype (n = 91, 79.8%). Isolates of this genotype were further analyzed by IS6110 RFLP. Sequencing of gene targets associated with INH and RIF resistance further showed that the MDR-TB strains are highly homogeneous as 78% of the MDR, SIT1 strains had the same resistance-conferring mutations. The genetic homogeneity of the MDR-TB strains indicates that they are actively transmitted in Murmansk.

Spin-asymmetric Josephson effect.

We propose that with ultracold Fermi gases one can realize a spin-asymmetric Josephson effect in which the two spin components of a Cooper pair are driven asymmetrically--corresponding to driving a Josephson junction of two superconductors with different voltages V(↑) and V(↓) for spin up and down electrons, respectively. We predict that the spin up and down components oscillate at the same frequency but with different amplitudes. Furthermore our results reveal that the standard interpretation of the Josephson supercurrent in terms of coherent bosonic pair tunneling is insufficient. We provide an intuitive interpretation of the Josephson supercurrent as interference in Rabi oscillations of pairs and single particles, the latter causing the asymmetry.

Self-reported psychosis-like experiences in patients with mood disorders.

BACKGROUND: Self-reported psychosis-like experiences (PEs) may be common in patients with mood disorders, but their clinical correlates are not well known. We investigated their prevalence and relationships with self-reported symptoms of depression, mania, anxiety, borderline (BPD) and schizotypal (SPD) personality disorders among psychiatric patients with mood disorders. METHODS: The Community Assessment of Psychic Experiences (CAPE-42), Mood Disorder Questionnaire (MDQ), McLean Screening Instrument (MSI), The Beck Depressive Inventory (BDI), Overall Anxiety Severity and Impairment Scale (OASIS) and Schizotypal Personality Questionnaire-Brief form (SPQ-B) were filled in by patients with mood disorders (n=282) from specialized care. Correlation coefficients between total scores and individual items of CAPE-42 and BDI, SPQ-B, MSI and MDQ were estimated. Hierarchical multivariate regression analysis was conducted to examine factors influencing the frequency of self-reported PE. RESULTS: PEs are common in patients with mood disorders. The "frequency of positive symptoms" score of CAPE-42 correlated strongly with total score of SPQ-B (rho=0.63; P<0.001) and moderately with total scores of BDI, MDQ, OASIS and MSI (rho varied from 0.37 to 0.56; P<0.001). Individual items of CAPE-42 correlated moderately with specific items of BDI, MDQ, SPQ-B and MSI (rφ varied from 0.2 to 0.5; P<0.001). Symptoms of anxiety, mania or hypomania and BPD were significant predictors of the "frequency of positive symptoms" score of CAPE-42. CONCLUSIONS: Several, state- and trait-related factors may underlie self-reported PEs among mood disorder patients. These include cognitive-perceptual distortions of SPD; distrustfulness, identity disturbance, dissociative and affective symptoms of BPD; and cognitive biases related to depressive or manic symptoms.

Ten-year outcomes after endovascular aneurysm repair (EVAR) and magnitude of additional procedures.

BACKGROUND AND AIMS: With any new technology complications are possible, and problems with first-generation aortic stentgrafts have been extensively reported. The longterm outcome of this patient population and the magnitude of additional secondary procedures are, however, less well covered. MATERIALS AND METHODS: Between February 1997 and November 1999, 48 patients (44 men and 4 women; mean age 70 years; range 54-85) with AAA (average 57mm, range 40-90mm) were treated with a Vanguard endoprosthesis. Stentgrafts were sized by CT and angiography-based measurements. Results were continuously assessed using contrast-enhanced CT before discharge, 1, 3, 6 and 12 months after the procedure and thereafter annually. Since 2001 plain abdominal X-rays have been performed annually. RESULTS: The technical implant success rate was 100%. Median follow-up was 91 months (range 7.6-120 months). None of the patients was lost during this period. Hospital mortality was 0%. There were 25 subsequent deaths (52%), the most common cause being coronary artery disease. There were ten late conversions to open surgical repair, including three emergency operations: two due to rupture and one to thrombosis. EVAR-related complications were encountered in 43 patients (90%): 12 primary endoleaks (all type II), 36 late endoleaks (16 type I, 2 type II and 18 type III), 22 migrations, 25 row separations, 20 thromboses, one endotension and 3 ruptures of the AAA. Secondary procedures were required in 39 patients (81%): 1 re-endografting by aortoiliac bifurcated graft and 3 with a uni-iliac graft; 33 limb graft repairs were performed and 19 infrarenal cuffs were placed. There were 4 late embolizations and 4 attempts, and 6 thrombolyses, four of which were successful. Further, 9 femoro-femoral crossover by-pass and 2 axillofemoral by-pass operations and 2 amputations were carried out during the follow-up. Only one patient was alive without complications. CONCLUSIONS: The impact of long-term follow-up of patients treated with the new technology was emphasized in this patient population. A careful surveillance protocol and active endovascular treatment of complications can yield acceptable results and low AAA rupture and aneurysm mortality rates, also with the first-generation endovascular graft. A new technology, however, may involve unpredictable problems which can magnify the workload and incur high costs over several years after the initial procedure.

Clinical and hemodynamical findings in legs with previous surgery of the great saphenous vein: role of the small saphenous vein.

AIM: To assess the role of small saphenous vein (SSV) reflux in patients with a long history of varicose disease and previous stripping of the great saphenous vein (GSV). METHODS: Consecutive patients with a history of GSV stripping 5-19 years earlier were enrolled in this prospective clinical study. A total of 101 legs of 75 consecutive patients fulfilled the study criteria: previous stripping of GSV from ankle to groin at least 5 years earlier, no history of thromboembolism and no previous surgery of deep veins or SSV. All patients were studied clinically using standardized classifications: clinical class, clinical disability score (CDS) and venous clinical scoring system (VCSS). Colour flow duplex imaging (CFDI) was used to assess reflux in deep and superficial veins. Details of prior surgery were evaluated. RESULTS: Overall, SSV reflux was noted in 28 (28%) of the legs, recurrent GSV (rGSV) in the thigh in 41 (41%), reflux in tributaries alone in 28 (28%) and a combination of SSV and rGSV reflux in 4 (3%). Segmental deep reflux was measured in 23 (23%) of the legs; the prevalence of deep reflux was significantly higher in complicated than in uncomplicated legs (12% versus 47%; P<0.05). Deep reflux was more frequently associated with SSV reflux than with rGSV reflux (50% versus 22%; P<0.05). The prevalence of SSV with or without deep reflux increased from 17% to 50% (P<0.05) when uncomplicated (C2-3) and complicated (C4-6) legs were compared. A similar increase was not seen in the legs with rGSV (39% versus 44%; P>0.05). SSV reflux without deep reflux was observed in 25% of the legs with complicated (C4-6) disease, whereas the prevalence of SSV reflux was low (9%) in uncomplicated (C2-3) legs. VCSS was higher in the legs with SSV reflux than in those with rGSV reflux. CDS scores tended to be higher in the SSV reflux group than in the legs with rGSV reflux or tributary reflux alone. After exclusion of deep reflux, the results remained at the same level. CONCLUSION: Small saphenous vein (SSV) reflux is common in legs with recurrent varicose veins and previous stripping of the GSV. SSV reflux alone is frequent in complicated legs, and SSV reflux is typically associated with segmental deep reflux. Clinical and hemodynamical findings stress the role of SSV reflux in this selected venous population.

Lower limb amputations: differences between the genders and long-term survival.

The purpose of the study was to evaluate possible differences between genders in amputation incidence, revascularization activity before and survival after amputation. This population-based study was carried out in a well-defined geographical area, where all vascular surgical consultations and reconstructions are performed in one university hospital. All amputations performed in the region during 1990 - 1999 were identified from the hospital central registers. According to patient's identity codes, the Cause of Death Registry of Statistics Finland provided death data. Amputation data were cross-linked with the local vascular registry using identity codes. Women were found to be 8 years older than men (p < 0.0001). Major amputations comprised 73.4% in males and 77.7% in females. The age-standardized amputation incidence among males was 338 and among females 226 (per 10(6) inhabitants/year) (p < 0.001). The most prominent difference was seen in amputations due to trauma, where the age-adjusted major amputation incidence was over three-fold among males compared to females. The proportion of patients who had undergone vascular procedure before amputation was 23% in both genders. Median survival after amputation was 943 days in men and 716 in women (p = 0.01). When the higher age of women was considered, there was no significant difference between the genders. Survival was poorer among diabetics in both genders and the difference was significant in males. The amputation incidence was found to be higher in men compared to women in all etiologic subgroups except malignant tumour. Almost one in 4 patients had undergone vascular surgical reconstruction before amputation in both genders. There was no significant difference between the genders in survival after amputation. Subjects with diabetes had a poorer survival after major amputation than those without diabetes.

Mediating role of borderline personality disorder traits in the effects of childhood maltreatment on suicidal behaviour among mood disorder patients.

BACKGROUND: Substantial evidence supports an association between childhood maltreatment and suicidal behaviour. However, few studies have examined factors mediating this relationship among patients with unipolar or bipolar mood disorders. METHODS: Depressive disorder and bipolar disorder (ICD-10-DCR) patients (n=287) from the Helsinki University Psychiatric Consortium (HUPC) Study were surveyed on self-reported childhood experiences, current depressive symptoms, borderline personality disorder traits, and lifetime suicidal behaviour. Psychiatric records served to complement the information on suicide attempts. We examined by formal mediation analyses whether (1) the effect of childhood maltreatment on suicidal behaviour is mediated through borderline personality disorder traits and (2) the mediation effect differs between lifetime suicidal ideation and lifetime suicide attempts. RESULTS: The impact of childhood maltreatment in multivariate models on either lifetime suicidal ideation or lifetime suicide attempts showed comparable total effects. In formal mediation analyses, borderline personality disorder traits mediated all of the total effect of childhood maltreatment on lifetime suicide attempts, but only one fifth of the total effect on lifetime suicidal ideation. The mediation effect was stronger for lifetime suicide attempts than for lifetime suicidal ideation (P=0.002) and independent of current depressive symptoms. CONCLUSIONS: The mechanisms of the effect of childhood maltreatment on suicidal ideation versus suicide attempts may diverge among psychiatric patients with mood disorders. Borderline personality disorder traits may contribute to these mechanisms, although the influence appears considerably stronger for suicide attempts than for suicidal ideation.

Level of functioning, perceived work ability, and work status among psychiatric patients with major mental disorders.

BACKGROUND: Major mental disorders are highly disabling conditions that result in substantial socioeconomic burden. Subjective and objective measures of functioning or ability to work, their concordance, or risk factors for them may differ between disorders. METHODS: Self-reported level of functioning, perceived work ability, and current work status were evaluated among psychiatric care patients with schizophrenia or schizoaffective disorder (SSA, n=113), bipolar disorder (BD, n=99), or depressive disorder (DD, n=188) within the Helsinki University Psychiatric Consortium Study. Correlates of functional impairment, subjective work disability, and occupational status were investigated using regression analysis. RESULTS: DD patients reported the highest and SSA patients the lowest perceived functional impairment. Depressive symptoms in all diagnostic groups and anxiety in SSA and BD groups were significantly associated with disability. Only 5.3% of SSA patients versus 29.3% or 33.0% of BD or DD patients, respectively, were currently working. About half of all patients reported subjective work disability. Objective work status and perceived disability correlated strongly among BD and DD patients, but not among SSA patients. Work status was associated with number of hospitalizations, and perceived work disability with current depressive symptoms. CONCLUSIONS: Psychiatric care patients commonly end up outside the labour force. However, while among patients with mood disorders objective and subjective indicators of ability to work are largely concordant, among those with schizophrenia or schizoaffective disorder they are commonly contradictory. Among all groups, perceived functional impairment and work disability are coloured by current depressive symptoms, but objective work status reflects illness course, particularly preceding psychiatric hospitalizations.

A prospective 1-year follow-up study in patients with functional or organic dyspepsia: changes in gastrointestinal symptoms, mental distress and fear of serious illness.

BACKGROUND: Psychosocial factors are common among patients with functional gastrointestinal disorders (FGIDs). Whether they affect the course of the disease remains unresolved. AIM: To evaluate whether reassuring investigations of primary care patients with functional dyspepsia (FD) and organic dyspepsia (OD) influence gastrointestinal (GI) symptoms and psychological factors, and to assess whether these changes are correlated. METHODS: Four hundred consecutive patients with dyspepsia were referred for thorough examinations. Patients completed questionnaires screening symptoms at baseline and on 1-year follow-up. RESULTS: At baseline, there was no difference in GI symptoms, prevalence of mental distress or fear of serious illness between patients with FD or OD. On follow-up, the patients with FD had more GI symptoms, but there was no difference in mental distress or fear of serious illness. Relevant GI symptom reduction related to alleviation of mental distress (53.4% vs. 20.5%, P < 0.001) and fear of serious illness (56.5% vs. 23.7%, P = 0.002), but reached statistical significance only in patients with OD. CONCLUSIONS: Gastrointestinal symptoms in FD patients are long lasting compared with those with organic diseases. Reassuring investigations could lower mental distress and fear of serious illness in these patients. Psychological factor change correlates with the change in GI symptom severity and is not specific to FGIDs.

Preoperative physical examination for primary vascular access--reliability in determining vessel quality.

BACKGROUND AND AIMS: The purpose of this prospective clinical study was to evaluate the reliability and adequacy of preoperative physical examination in determining the quality of vessels prior to primary vascular access procedure by performing peroperative completion fistulography. MATERIAL AND METHODS: 26 consecutive patients who were scheduled for primary vascular access surgery, between July 2001 and June 2002, were included. Findings between the preoperative physical examination and peroperative completion fistulography were compared. RESULTS: Of the 26 patients that were initially enrolled in the study, 4 patients were excluded because physical examination showed poor superficial arm veins and 2 patients had not undergone access procedure by the end of the study. The remaining twenty patients constituted the actual study group. The arteriovenous fistula could be performed at the chosen level and way in all 20 patients. The findings between preoperative physical examination and peroperative fistulography were compatible and the specificity of physical examination to detect patent inflow and outflow vessels was 100%. Due to the fact that 4 patients in whom a poor vein was suspected were excluded, the sensitivity could not be assessed. CONCLUSIONS: Preoperative physical examination seems to be reliable and adequate method in determining vessel quality prior primary vascular access surgery. According to our study, its specificity is high in determining patent inflow and out-flow vessels. However, because of exclusion of patients with suspected problem, sensitivity cannot be determined.

Self-reported symptoms of schizotypal and borderline personality disorder in patients with mood disorders.

BACKGROUND: Distinguishing between symptoms of schizotypal (SPD) and borderline personality disorders (BPD) is often difficult due to their partial overlap and frequent co-occurrence. We investigated correlations in self-reported symptoms of SPD and BPD in questionnaires at the levels of both total scores and individual items, examining overlapping dimensions. METHODS: Two questionnaires, the McLean Screening Instrument (MSI) for BPD and the Schizotypal Personality Questionnaire Brief (SPQ-B) for SPD, were filled in by patients with mood disorders (n=282) from specialized psychiatric care in a study of the Helsinki University Psychiatric Consortium. Correlation coefficients between total scores and individual items of the MSI and SPQ-B were estimated. Multivariate regression analysis (MRA) was conducted to examine the relationships between SPQ-B and MSI. RESULTS: The Spearman's correlation between total scores of the MSI and SPQ-B was strong (rho=0.616, P<0.005). Items of MSI reflecting disrupted relatedness and affective dysregulation correlated moderately (rφ varied between 0.2 and 0.4, P<0.005) with items of SPQ. Items of MSI reflecting behavioural dysregulation correlated only weakly with items of SPQ. In MRA, depressive symptoms, sex and MSI were significant predictors of SPQ-B score, whereas symptoms of anxiety, age and SPQ-B were significant predictors of MSI score. CONCLUSIONS: Items reflecting cognitive-perceptual distortions and affective symptoms of BPD appear to overlap with disorganized and cognitive-perceptual symptoms of SPD. Symptoms of depression may aggravate self-reported features of SPQ-B, and symptoms of anxiety features of MSI. Symptoms of behavioural dysregulation of BPD and interpersonal deficits of SPQ appear to be non-overlapping.

Anxiety symptoms in a major mood and schizophrenia spectrum disorders.

BACKGROUND: Comorbid anxiety symptoms and disorders are present in many psychiatric disorders, but methodological variations render comparisons of their frequency and intensity difficult. Furthermore, whether risk factors for comorbid anxiety symptoms are similar in patients with mood disorders and schizophrenia spectrum disorders remains unclear. METHODS: The Overall Anxiety Severity and Impairment Scale (OASIS) was used to measure anxiety symptoms in psychiatric care patients with schizophrenia or schizoaffective disorder (SSA, n=113), bipolar disorder (BD, n=99), or depressive disorder (DD, n=188) in the Helsinki University Psychiatric Consortium Study. Bivariate correlations and multivariate linear regression models were used to examine associations of depressive symptoms, neuroticism, early psychological trauma and distress, self-efficacy, symptoms of borderline personality disorder, and attachment style with anxiety symptoms in the three diagnostic groups. RESULTS: Frequent or constant anxiety was reported by 40.2% of SSA, 51.5% of BD, and 55.6% of DD patients; it was described as severe or extreme by 43.8%, 41.4%, and 41.2% of these patients, respectively. SSA patients were significantly less anxious (P=0.010) and less often avoided anxiety-provoking situations (P=0.009) than the other patients. In regression analyses, OASIS was associated with high neuroticism, symptoms of depression and borderline personality disorder and low self-efficacy in all patients, and with early trauma in patients with mood disorders. CONCLUSIONS: Comorbid anxiety symptoms are ubiquitous among psychiatric patients with mood or schizophrenia spectrum disorders, and in almost half of them, reportedly severe. Anxiety symptoms appear to be strongly related to both concurrent depressive symptoms and personality characteristics, regardless of principal diagnosis.

Combination chemotherapy versus single-agent therapy as first- and second-line treatment in metastatic breast cancer: a prospective randomized trial.

PURPOSE: We report results of a randomized prospective study that compared single agents of low toxicity given both as the first-line and second-line chemotherapy with combination chemotherapy in advanced breast cancer with distant metastases. PATIENTS AND METHODS: Patients in the single-agent arm (n = 153) received weekly epirubicin (E) 20 mg/m2 until progression or until the cumulative dose of 1,000 mg/m2, followed by mitomycin (M) 8 mg/m2 every 4 weeks, and those in the combination chemotherapy arm (n = 150) were first given cyclophosphamide 500 mg/m2, E 60 mg/m2, and fluorouracil 500 mg/m2 three times per week (CEF) followed by M 8 mg/m2 plus vinblastine (V) 6 mg/m2 every 4 weeks. Exclusion criteria included age greater than 70 years, World Health Organization (WHO) performance status greater than 2, prior chemotherapy for metastatic disease, and presence of liver metastases in patients younger than 50. RESULTS: An objective response (complete [CR] or partial [PR]) was obtained in 55%, 48%, 16%, and 7% of patients treated with CEF, E, M, and MV, respectively. A response to CEF tended to last longer than a response to E (median, 12 v 10.5 months; P = .07). Treatment-related toxicity was less in the single-agent arm and quality-of-life (QOL) analysis favored the single-agent arm. No significant difference in time to progression or survival was found between the two arms. Similarly, no difference in survival was found when the patients who received both the planned first-and second-line treatments were compared or when survival was calculated from the beginning of the second-line therapy. CONCLUSION: Patients treated with single-agent E followed by single-agent M had similar survival, but less treatment-related toxicity and better QOL as compared with those treated with CEF followed by MV.

Mental distress in patients with functional or organic dyspepsia: a comparative study with a sample of the general population.

BACKGROUND: It has been argued that patients with functional gastrointestinal disorders have mental disorders more often than healthy controls and patients with organic disease. Most studies surveying psychological factors at the population level have relied on symptom questionnaires to diagnose functional dyspepsia. However, the symptom patterns alone are unable to adequately discriminate organic from functional dyspepsia. AIM: To evaluate the frequency of mental distress in primary care patients with organic or functional dyspepsia and compare the findings with a sample of the Finnish general population. METHODS: Four-hundred consecutive, unselected dyspeptic patients were referred for upper gastrointestinal endoscopy and other diagnostic examinations. All patients compiled a self-administered questionnaire including the 12-item General Health Questionnaire to detect cases of recent mental disorders. RESULTS: The prevalence of mental distress among patients with functional and organic dyspepsia was 38 and 36.4% respectively. The sex- and age-adjusted risk of having mental distress was nearly fourfold higher among patients with dyspepsia than in the general population. CONCLUSION: Mental distress is common among patients with functional or organic dyspepsia. Nevertheless, there is no difference between patients with functional or organic dyspepsia in the prevalence or risk of mental distress.

First-line eradication therapy for Helicobacter pylori in primary health care based on antibiotic resistance: results of three eradication regimens.

AIM: To determine the efficacy of three Helicobacter pylori eradication regimens and factors affecting the eradication results in Finland. METHODS: A total of 342 H. pylori-positive adult patients from primary health care referred for gastroscopy at 23 centres in different parts of Finland were randomized to receive either (i) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and metronidazole 400 mg t.d.s. (LAM), (ii) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and clarithromycin 500 mg b.d. (LAC), or (iii) ranitidine bismuth citrate 400 mg b.d., metronidazole 400 mg t.d.s. and tetracycline 500 mg q.d.s. (RMT). A (13)C-urea breath test was performed 4 weeks after therapy. RESULTS: The eradication result could be assessed in 329 cases. Intention-to-treat cure rates of LAM, LAC, and RMT were 78, 91 and 81%. The difference was significant between LAM and LAC (P = 0.01) and between LAC and RMT (P = 0.04). The eradication rates in cases with metronidazole-susceptible vs. -resistant isolates were for LAM 93% vs. 53% (P = 0.00001), for LAC 95% vs. 84%, and for RMT 91% vs. 67% (P = 0.002). Previous antibiotic use, smoking, and coffee drinking reduced the efficacy of therapy. CONCLUSIONS: In unselected patients in primary health care, LAC was the most effective first-line eradication.

The profile of leg symptoms, clinical disability and reflux in legs with previously operated varicose disease.

PURPOSE: It is difficult to assess the severity and location of venous insufficiency in legs with recurrent varicose disease. This present purpose was to evaluate the distribution of reflux and the diagnostic role of current classifications in a consecutive series of legs with previously operated varicose disease. METHODS: A total of 90 legs in a cohort of 66 patients were included. The examination comprised CEAP clinical class, clinical disability score (CDS) and leg symptoms. Colour-flow duplex imaging (CFDI) was used to observe reflux in deep and superficial veins. Details of prior surgery were assessed. RESULTS: The site of superficial reflux was at the groin in 58% (recurrent or residive vein trunk or unoperated great saphenous vein), and the rate in the popliteal fossa was 11% (unoperated short saphenous vein). In 58% of the legs presenting superficial reflux at groin level, previous surgery at the saphenofemoral junction was noted. A sensation of pain was observed in 74% of the legs, sensation of oedema in 64%, itching in 26 %, and night cramps in 8%, respectively. Only itching was significantly infrequent in uncomplicated (CEAP C 2-3) legs, and in legs with local reflux was restricted to vein tributaries. Higher CDS (classes 2-3) were significantly more frequent among complicated legs (CEAP clinical class C2-3: 22% versus CEAP clinical class C4-6: 77%; p < 0.005). A similar situation was noted when legs with only local reflux were compared to those with more severe reflux (local reflux: 7% versus severe reflux: 48%; p < 0.005). CONCLUSIONS: Superficial reflux is frequently detected at groin level despite prior surgery. Unstructured evaluation of leg symptoms is not beneficial. Clinical disability scores associate well with the severity of the venous disease.
