A prospective cohort study of practice guidelines in inflammatory bowel disease

OBJECTIVES: Practice guidelines should improve care, but they are not routinely followed, in part because of lack of proven benefit. We evaluated the effect of introducing guidelines for inflammatory bowel disease (IBD) on practice variation and the IBD Quality of Life (IBDQ) score. METHODS: This was a prospective, controlled, cohort study. A total of 65 patients were matched according to month of visit, diagnosis, and disease activity with control subjects seen 1 yr earlier. Physicians were educated throughout the study regarding the guidelines. Variation was measured by the Mayo Practice Guideline Score (MPGS), a 15-point assessment of documentation of diagnosis, nutrition, social support, education, functional status, and treatment. The IBDQ was measured at baseline and at 1 yr in the intervention group and after 1 yr in the control group. RESULTS: The MPGS was significantly higher in the intervention group compared to the controls (p = 0.002), with median values of 12 versus 11. The IBDQ median score increased significantly in the intervention group (p < 0.001), baseline median of 133 versus 15-month median of 184. However, the final IBDQ was not significantly higher in the intervention group than in the controls (p = 0.33). CONCLUSIONS: Practice guidelines for IBD reduce practice variation. The quality of life improved significantly compared to baseline with practice guidelines, but not compared to controls, perhaps because of the small sample size and homogenous practice setting. The MPGS is a tool that can be used in day-to-day management of IBD patients.     

Incidence of congenital hemolytic anemias in young cholelithiasis patients

AIM: To clarify the incidence of congenital hemolytic anemias (CHA) in young cholelithiasis patients and to determine a possible screening test based on the results. METHODS: Young cholelithiasis patients (< 35 years) were invited to our outpatient clinic. Participants were asked for comorbidities and family history. The number of gallstones were recorded. Blood samples were obtained to perform a complete blood count, standard Wright-Giemsa staining, reticulocyte count, hemoglobin (Hb) electrophoresis, serum lactate dehydrogenase and bilirubin levels, and lipid profile. RESULTS: Of 3226 cholecystectomy patients, 199 were under 35 years, and 190 with no diagnosis of CHA were invited to take part in the study. Fifty three patients consented to the study. The median age was 29 years (range, 17-35 years), 5 were male and 48 were female. Twelve patients (22.6%) were diagnosed as thalassemia trait and/or ?ron-deficiency anemia. Hblevels were significantly lower (P = 0.046), and mean corpuscular volume (MCV) and hematocrit levels were slightly lower (P = 0.072 and 0.082, respectively) than normal. There was also a significantly lower number of gallstones with the diagnosis (P = 0.007). CONCLUSION: In endemic regions, for young cholelithiasis patients (age under 35) with 2-5 gallstones, the clinician/surgeon should pay attention to MCV and Hb levels as indicative of CHA.     

Effects of a specially pulsed electric field on an animal model of wound healing

The possible beneficial effects of a specially pulsed electric field (PEF) on wound healing were investigated in this study. We made a pair of triangular, full-thickness, dorsal incisions in the skin of 32 healthy male mice (one control group and three exposure groups). The treatment groups were kept between parallel plates in a partially insulated exposed environment. Group I was exposed to an electric field intensity of 10 kV/m, group II was exposed to 1.9 kV/m, and group III was exposed to 0.9 kV/m. PEFs were applied to the subjects for 20–22 h and 8 consecutive days. We determined the differences in wound recovery between the groups based on the following parameters: collagen fiber density, inflammatory infiltration density, capillary proliferation, and existence of exudates. We found that a 0.9 kV/m–1.9 kV/m chopped direct current (DC) electric field with a 30 μs repetition time favorably affected collagen synthesis and wound recovery. Despite the intensity of 0.9–1.9 kV/m, PEF accelerated healing, but 10 kV/m decelerated this recovery process.     

Predictors and clinical significance of angiographically detected distal embolization after primary percutaneous coronary interventions

OBJECTIVES: The aim of this study was to investigate clinical, angiographic and procedural predictors of distal embolization (DE) on angiography after primary percutaneous coronary intervention (PCI). The impact of DE on outcome in the first 30 days was also assessed. METHODS: Between January 2004 and April 2006, primary PCI was performed in 212 consecutive patients with acute myocardial infarction (AMI) of < or = 12-h duration. RESULTS: Distal embolization was present in 27 patients (12.7%) and more often observed in female sex (27.5 vs. 10.4%, P=0.01), in patients with right coronary artery involvement (52 vs. 28%, P=0.02), prerevascularization thrombolysis in myocardial infarction flow < or = 1 (89 vs. 69%, P=0.03), in the presence of high thrombus burden (92.6 vs. 39.5%, P=0.0009), and a long target lesion in the infarct-related artery (>14.5 mm, 74 vs. 29%, P<0.0001). By multiple stepwise logistic regression analysis, only the presence of high thrombus burden before the PCI procedure [odds ratio (OR)=5.2, 95% confidence interval (CI)=1.09-24.97, P=0.03)] and target lesion length (>14.5 mm, OR=3.9, 95% CI=1.45-10.60, P=0.007) were found independent predictors of DE. Patients with DE had an increased risk of target vessel revascularization (26 vs. 5%, P=0.001) and short-term mortality (29.6 vs. 7.5%, P=0.002) when compared with patients without angiographic signs of embolization. CONCLUSIONS: In patients who undergo primary PCI, high thrombus burden on angiography before PCI and/or a long target lesion in the infarct-related artery increase the risk of DE and subsequent short-term mortality.     

Seroprevalence of Toxoplasma gondii, rubella and cytomegalovirus among pregnant women in southern Turkey

Primary infections caused by Toxoplasma gondii, rubella and cytomegalovirus (CMV) can lead to serious complications in pregnant women. The aim of this study was to determine the seroprevalence of Toxoplasma, rubella and CMV infections through antenatal screening. In this study, the consecutive records of 1652 pregnant women examined between the period March 2004 to January 2006 were included. The results of the antenatal screening for Toxoplasma, rubella and CMV during the first trimester of pregnancy were evaluated. Anti-Toxoplasma, anti-rubella and anti-CMV IgG and IgM antibodies were assayed using an enzyme linked immunosorbent assay method. Of the 1652 pregnant women tested, anti-Toxoplasma IgG antibody was found in 860 (52.1%) of the cases, while 9 (0.54%) of the subjects tested positive for anti-Toxoplasma IgM. Anti-rubella IgG and IgM antibodies were reactive in 1570 (95.0%), and in 9 (0.54%) of the tested women, respectively. Moreover, 1568 (94.9%) of them were found to be positive for anti-CMV IgG, while 7 (0.4%) tested positive for anti-CMV IgM. Consequently, because of the high seropositivity of T. gondii, rubella and CMV in the pregnant women, the country's health authorities should be alerted, and preventive measures should be taken.
