Our objective was to describe a group of ALS patients who underwent percutaneous endoscopic gastrostomy (PEG) insertion, with emphasis on the respiratory function, by comparing patients with forced vital capacity (FVC) > 30% versus FVC ≤ 30%, and the effect of respiratory dysfunction on the perioperative complication rate and survival. Thirty consecutive ALS patients in whom FVC status was known underwent PEG insertion at our centre. Twenty of them had FVC > 30% (50.1% ± 20) at the time of the procedure, and 10 had FVC ≤ 30% (20.1% ± 7). Demographic and clinical data were reviewed in each patient. Results showed that all patients had successful PEG insertion without any complications. There was no statistically significant difference between the two FVC groups regarding survival after the date of PEG insertion. In conclusion, in this relatively small patient sample there was no difference in complication rate and survival after PEG insertion between patients with poor respiratory function (FVC ≤ 30%) at the time of the procedure and patients with better respiratory function (FVC > 30%). Therefore, according to our data, PEG insertion may be regarded as safe even in patients with low FVC and should be offered even to patients with respiratory dysfunction.

Levan is a commonly used dietary fiber of the fructans group. Its impact on health remains undetermined. This double blind controlled study aimed to investigate the effect of 8 weeks’ daily consumption of 500 mL of natural orange juice enriched with 11.25 g of levan compared to the same amount of natural orange juice without levan on weight, gastrointestinal symptoms and metabolic profiles of 48 healthy volunteers. The statistical analyses compared between- and within-group findings at baseline, 4 weeks and study closure. The compared parameters were: weight, blood pressure, blood laboratory tests, daily number of defecations, scores of stool consistency, abdominal pain, bloating, gas, dyspepsia, vomiting and heartburn. Despite a higher fiber level recorded in the study group, there was no significant difference in the effect of the two kinds of juices on the studied parameters. Both juices decreased systolic and diastolic pressures, increased sodium level (within normal range), stool number, and bloating scores, and decreased gas scores. In conclusion, levan itself had no effect on weight, gastrointestinal symptoms or metabolic profile of healthy volunteers. Its possible effect on obese, hypertensive or hyperlipidemic patients should be investigated in further studies.

Renal vein thrombosis and membranous glomerulopathy in a patient homozygote for factor V Leiden mutation: A mere coincidence?

Alanine aminotransferase (ALT) activity is the most widely used laboratory test for the recognition of liver disease. Normality limits for values of serum ALT activity have been questioned lately. One reason for this recent uncertainty may be an unrecognized decline in aminotransferase levels in the aging population.Cross-sectional evaluation of the association between age and ALT activity.Laboratory data of residents in single home for the aged and of adult subjects in three general practice clinics in Jerusalem, Israel were reviewed, excluding subjects with known liver disease. A single laboratory performed all the tests. We examined the associations of serum aminotransferase levels with age, sex, body-mass-index (BMI), and estimated glomerular filtration rate (GFR). Polynomial regression and analysis of variance (ANOVA) with corrections for multiple comparisons were utilized for the statistical analyses.One hundred and twenty-eight individuals from the home for the aged and 207 individuals from three family practices were included. ALT activity linearly regressed with age (r = 0.22, p0.0001). However, polynomial regression revealed a better fit (r = 0.33, p0.0001), creating an inverted U curve with a peak at 40-55 yr. According to age groups, serum ALT level was 19 +/- 13 U/L in those under 40 yr, 25 +/- 19 U/L in 40-55 yr olds, 22 +/- 10 U/L in 56-72 yr olds, 17 +/- 9 U/L in 73-83 yr olds, and 13 +/- 5 U/L in 83-100 yr olds (p0.0001). GFR (r = 0.1, p0.05) and BMI (r = 0.14, p0.01) weakly correlated with ALT. Gender also associated with ALT; 22 +/- 15 U/L in men, and 17 +/- 11 U/L in women (p0.005). Multiple regression analysis including age, gender, GFR, and BMI revealed that age (p= 0.01) and gender (p= 0.04) retained association with ALT activity. No such associations were noted for aspartate aminotransferase (AST) activity.Our data suggest a significant association between age and serum ALT activity. This association is not a simple linear correlation, but rather an inverted-U-like relation. Thus, when interpreting the laboratory results of a subject suspected of liver disease, age should probably be taken into account. Larger-scale studies are needed to better characterize this issue.

Angiotensin converting enzyme (ACE) is a candidate gene for psychiatric disorders. We examined the frequency of a functional insertion/deletion (I/D) polymorphism in the 16th intron of the ACE gene (located on chromosome 17q23) in groups of patients with schizophrenia (n = 104 and 113), major depression (n = 55), and bipolar disorder (n = 87) compared to healthy control subjects (n = 87). There was no evidence for allelic or genotypic association of the polymorphism with any of the disorders or with tardive dyskinesia (TD) in patients with schizophrenia. In a sample of nuclear families (n = 61) made up of one or more patients with schizophrenia recruited with their parents, there was no evidence for biased transmission of ACE I/D alleles. Particularly in the case of schizophrenia, these findings do not support an association of the ACE I/D polymorphism with the phenotypes examined. © 2002 Wiley-Liss, Inc.

Background and aim Limited data suggests that pseudomembranes are uncommon in patients with inflammatory bowel disease (IBD) and C. difficile associated disease (CDAD), but the reason for this is unknown. We aimed to evaluate the rate of pseudomembranes in this population, identify predictive factors for pseudomembranes' presence and assess its clinical impact. Methods This was a sub-study of a retrospective European Crohn's & Colitis Organization (ECCO) multi-center study on the outcome of hospitalized IBD patients with C. difficile. The present study included only patients who underwent lower endoscopy during hospitalization, and compared demographic and clinical parameters in the group of patients with discernable pseudomembranes versus those without. Results Out of 155 patients in the original cohort, 93 patients underwent lower endoscopy and constituted the study population. Endoscopic pseudomembranes were found in 12 (13%) of these patients. Patients with pseudomembranes presented more commonly with fever (p = 0.02) compared to patients without pseudomembranes. No difference between the two groups was found with respect to the use of immunosuppressant drugs, background demographics or disease characteristics. Neither was there a difference between the group with or without pseudomembranes in the frequency of severe adverse clinical outcome or in the duration of hospitalization. On multi-variate analysis the presence of fever remained independently associated with the finding of pseudomembranes (OR 6, 95% CI 1.2–32, p = 0.03). Conclusions This study documents that hospitalized IBD patients with CDAD have low rate of endoscopic pseudomembranes, which is not accounted for by the use of immunosuppressant drugs. IBD patients with CDAD and discernable pseudomembranes more commonly present with fever, but their clinical outcome is similar to patients without pseudomembranes.

Amitraz is commonly used in agricultural industries throughout the world as a farm-animal insecticide. Despite its widespread use, amitraz intoxication is extremely rare and mainly occurs through accidental ingestion by young children. Severe, life-threatening amitraz intoxication in adults is very rarely recognized and reported. Described herein is a previously healthy 54-year-old patient who accidentally ingested a mouthful of liquid amitraz concentrate, and rapidly developed life-threatening clonidine-like overdose syndrome, manifested as nausea, vomiting, hypotension, bradycardia, bradypnoea, and deep coma. Supportive treatment, including mechanical ventilation, and atropine administration resulted in full recovery within 48 hr. Very few cases of near-fatal amitraz poisoning in adults have been described in the medical literature, leading to low awareness of physicians in general practice to the potential toxicity of amitraz. As a consequence, cases of amitraz poisoning are not recognised and therefore erroneously treated as the much more commonly recognized organophosphate and carbamate intoxication. In our discussion, we review the clinical and laboratory manifestations of amitraz poisoning, including clinical hints that aid in the recognition of this often-overlooked diagnosis. Differentiation of amitraz intoxication from the much more commonly seen pesticide-related organophosphate and carbamate intoxication is of utmost importance, in order to avoid erroneous, unnecessary, and often dangerous treatment.
