Self-reported health-related quality of life of children and adolescent survivors of extracranial childhood malignancies: a Finnish nationwide survey

Purpose  

The purpose of this Finnish total cohort survey was to assess and compare the self-reported health-related quality of life (HRQL) in childhood cancer survivors to that of matched controls, to analyse demographic and disease-related factors explaining survivors’ HRQL, and to compare the results of two different HRQL instruments, 16D/17D and PedsQL™.     

Cingulate gyrus morphology in children and adolescents with fetal alcohol spectrum disorders

Alcohol consumption during pregnancy can lead to a variety of cognitive and other birth defects, collectively termed fetal alcohol spectrum disorders (FASD), and including the Fetal Alcohol Syndrome (FAS). This study examined the impact of gestational alcohol exposure on the morphology of the cingulate gyrus, given this region's role in cognitive control, attention, and emotional regulation, all of which are affected in children with FASD. Thirty-one youth (ages 8–16) with histories of heavy prenatal alcohol exposure (n = 21) and demographically matched comparison subjects (n = 10) underwent structural magnetic resonance imaging. The cingulate gyrus was manually delineated, and parcellated volumes of grey and white matter were compared across groups. Alcohol-exposed individuals had significantly smaller raw cingulate grey matter, white matter, and tissue volumes compared with controls. After adjustment for respective cranial tissue constituents, only white matter volumes remained significantly reduced, and this held regardless of whether or not the child qualified for a diagnosis of FAS. A correlation between posterior cingulate grey matter volume and the WISC-III Freedom from Distractibility Index was also observed in alcohol-exposed children. These data suggest that cingulate white matter is compromised beyond global white matter hypoplasia in alcohol-exposed individuals, regardless of FAS diagnosis. The observed volumetric reductions in the cingulate gyrus may contribute to the disruptive and emotionally dysregulated behavioral profile commonly observed in this population.     

The Role of the Template in Prosthetically Guided Implantology

In prosthetically guided implantology, where ideal placement of implants is determined by the definitive restoration, the use of a radiographic/surgical template plays an essential role. This article describes how to fabricate a radiographic/surgical template to be used for radiographic diagnosis of the selected implant sites and as a guide during surgery for the insertion of the implant with correct angulation.     

Evaluation of a commercial serological kit for detection of salivary immunoglobulin G to Helicobacter pylori: a multicentre study

OBJECTIVE: To evaluate the usefulness of a commercial serological enzyme immunoassay (EIA) for detecting salivary immunoglobulin (Ig) G to Helicobacter pylori. DESIGN: Prospective, multicentre study. SETTING: The study was conducted at 11 gastroenterology hospital centres throughout Italy. PARTICIPANTS AND INTERVENTIONS: Two hundred and thirteen dyspeptic patients underwent gastroscopy with antral biopsies. At each centre, two of the following three tests for H. pylori diagnosis were performed: urease quick test, histology, and 13C-urea breath test. Samples of unstimulated saliva and venous blood were collected from each patient. Salivary and serum H. pylori IgG were determined with the EIA Helori-test IgG (Eurospital, Trieste, Italy). MAIN OUTCOME MEASURES: Sensitivity, specificity, positive and negative predictive values, and accuracy of the salivary and serum EIAs. RESULTS: By using a receiver operating characteristic curve, salivary EIA yielded 81% (95% confidence interval 73-87%) sensitivity, 73% (62-83%) specificity, 84% (76-90%) positive predictive value, 69% (58-79%) negative predictive value, and 78% (72-84%) accuracy. At the cut-off suggested by the manufacturer, serum EIA had 90% (84-95%) sensitivity, 78% (67-86%) specificity, 88% (81-93%) positive predictive value, 82% (71-90%) negative predictive value, and 86% (81-91%) accuracy. CONCLUSION: In this large multicentre study, detection of salivary H. pylori IgG with a commercial serological EIA was a fairly accurate diagnostic method. Data confirm that saliva testing does not compare favourably with serology in the assessment of H. pylori status.     

HLA-haploidentical blood progenitor cell transplantation in osteopetrosis

Infantile osteopetrosis (OP) carries an extremely poor prognosis unless treated early by hematopoietic stem cell transplantation. We explored the use of purified blood progenitor cells from HLA-haploidentical parents in 7 patients lacking suitable matched donors. Blood progenitor cells were purified by positive selection and by additional T-cell depletion using rosette formation. For conditioning, patients received busulfan, thiotepa, and either cyclophosphamide (5 patients) or fludarabine (2 patients). Stable donor engraftment developed in 6 of 7 patients. Graft-versus-host disease was not observed. Three of the 7 patients had no major complications and 4 of 7 had both veno-occlusive disease and respiratory failure. Five of 7 patients survive with complete cure of OP at a median of 4 years. Patients with OP lacking HLA-matched donors can be successfully treated by transplantation of purified blood progenitor cells from HLA-haploidentical donors.     

Probability of liver cancer and survival in HCV-related or alcoholic-decompensated cirrhosis. A study of 377 patients.

BACKGROUND: Although chronic alcohol intake and chronic hepatitis C may progress to cirrhosis and hepatocellular carcinoma (HCC), few data are available about survival and probability of developing HCC in decompensated cirrhosis of both aetiologies. METHODS: This study identified factors related with probability of developing HCC and survival in a cohort of 377 consecutive patients with decompensated HCV-related cirrhosis (200 cases) or alcoholic cirrhosis (177 cases) without known HCC, hospitalized for their first hepatic decompensation, as well as to evaluate differences between both aetiologies. Patients were followed for a mean period of 39 +/- 2 months. RESULTS: During follow-up, 42 patients (11.1%) developed HCC (16.5% vs 5.1%) in groups HCV and alcohol, respectively; p = 0.0008), and 131 patients (34.7%) died (42% vs 26.6% in groups HCV and alcohol, respectively; p = 0.002). Age and HCV-cirrhosis were independently related to HCC development, while baseline age and Child-Turcotte-Pugh score were independently correlated with survival. CONCLUSION: Survival in decompensated HCV-related or alcoholic cirrhosis is influenced by age and baseline Child-Turcotte-Pugh score, without differences in cirrhosis aetiology. The risk of developing HCC is greater in HCV-related cirrhosis than in alcoholic cirrhosis.     

Influenza vaccination in patients with end-stage renal disease

Introduction: Patients with end-stage renal disease (ESRD) are considered at higher risk of influenza-related complications and are listed worldwide among the subjects for whom yearly influenza vaccination is strongly recommended. However, influenza vaccination coverage of patients with ESRD is significantly lower than desired.

Areas covered: This paper explores why compliance with official recommendations for influenza vaccination is poor in patients with ESRD and analyzes the true risk of infection as well as the immunogenicity, the effectiveness and the safety of influenza vaccination in these patients.

Expert opinion: Epidemiological and clinical data support the importance of influenza in conditioning clinical deterioration of patients with ESRD, particularly in relation to their level of immunosuppression. However, the variable levels of immunodeficiency detected in patients with ESRD may reduce the immune response to influenza vaccination, which appears to be lower than that usually found in healthy subjects. However, few studies are available, and they are difficult to compare for several reasons. Additionally, limited data have been collected on influenza vaccine effectiveness, although the available studies support positive results of vaccination on outcomes of severe disease. Despite such limitations, it is important to highlight that all the available studies have confirmed the good safety and tolerability of inactivated influenza vaccines. These findings, together with the risks associated with influenza in these patients, support annual influenza vaccination in patients with ESRD as well as vaccination of their close contacts and should be presented in educational programs organized for nephrologists and patient associations.     

Evaluation of interleukin-6 and its soluble receptor components sIL-6R and sgp130 as markers of inflammation in inflammatory bowel diseases

Purpose

Interleukin-6 (IL-6) production and signalling are increased in the inflamed mucosa in inflammatory bowel diseases (IBD). As published serum levels of IL-6 and its soluble receptors sIL-6R and sgp130 in IBD are from small cohorts and partly contradictory, we systematically evaluated IL-6, sIL-6R and sgp130 levels as markers of disease activity in Crohn’s disease (CD) and ulcerative colitis (UC).

Methods

Consecutive adult outpatients with confirmed CD or UC were included, and their disease activity and medication were monitored. Serum from 212 CD patients (815 measurements) and 166 UC patients (514 measurements) was analysed, and 100 age-matched healthy blood donors were used as controls.

Results

IL-6 serum levels were significantly elevated in active versus inactive CD and UC, also compared with healthy controls. However, only a fraction of IBD patients showed increased serum IL-6. IL-6 levels ranged up to 32.7 ng/mL in active CD (>?5000-fold higher than in controls), but also up to 6.9 ng/mL in inactive CD. Increases in active UC (up to 195 pg/mL) and inactive UC (up to 27 pg/mL) were less pronounced. Associations between IL-6 serum levels and C-reactive protein concentrations as well as leukocyte and thrombocyte counts were observed. Median sIL-6R and sgp130 levels were only increased by up to 15%, which was considered of no diagnostic significance.

Conclusions

Only a minority of IBD patients shows elevated IL-6 serum levels. However, in these patients, IL-6 is strongly associated with disease activity. Its soluble receptors sIL-6R and sgp130 do not appear useful as biomarkers in IBD.
