Mouse genetic model for antigen-induced airway manifestations of asthma.

Allergic asthma is a genetically complex disease characterized by allergen-specific immunoglobulin (Ig)E, eosinophilic inflammation of the lungs and airway hyper-responsiveness to bronchospasmogenic stimuli. In this study, we compared 13 recombinant congenic (RC) mouse strains in an ovalbumin model of allergic asthma. Different intensities and types of responses are observed throughout the RC strains.

Intestinal transplantation in The Netherlands: first experience and future perspectives.

Intestinal transplantation for intestinal failure is no longer an experimental procedure, but an accepted treatment for patients who fail total parenteral nutrition (TPN) therapy. Early referral for evaluation for small bowel transplantation has to be considered in patients with permanent intestinal failure who have occlusion of more than two major veins, frequent line-related septic episodes, impairment of liver function or an unacceptable quality of life. With the increased experience in post-transplant patient care and newer forms of induction (thymoglobulin, IL-2 receptor antagonists) and maintenance (tacrolimus) therapies the 1-year graft survival has increased to 65% for isolated and to 59% for liver/small bowel transplantation, and is further improving.

Automated erythrocytapheresis in severe falciparum malaria: A critical appraisal.

Imported falciparum malaria is increasing in Western countries. In patients with severe disease, exchange transfusion has been added to antimalarial and conventional supportive therapy to increase removal of parasitized erythrocytes, but hemodynamic compromise limits its use; automated erythrocytapheresis may be advantageous. We review published reports of patients with severe falciparum malaria treated by automated erythrocytapheresis combined with standard therapy and add three more cases to the literature.

Clinical efficacy of agomelatine in depression: the evidence.

Despite the advances of recent decades, there is still an urgent need for antidepressants with improved efficacy, safety and tolerability. Agomelatine is a new antidepressant with an innovative pharmacological profile. It is the first melatonergic antidepressant, and is a potent agonist of melatonin receptors (MT1 and MT2) with 5-HT2C antagonist properties.

Chronic lymphocytic leukaemia: a review of the immuno-architecture.

Immunophenotyping of B cell chronic lymphocytic leukaemia (B-CLL) is usually performed by flow cytometry on cell suspensions obtained from peripheral blood, bone marrow or biopsied tissue. Immunohistochemical analysis on routine sections is less commonly performed; however, this approach allows the pathologist and the researcher to appreciate the immuno-architecture of the involved tissues and to gain insight into some of the events that influence the biology of the disease. In this review the authors focus on the following issues: immuno-architecture of the proliferation centres, expression of CD23, MUM1/IRF-4 and cyclin D1, tyrosine phosphorylation and detection of the ZAP-70 kinase.

Initial cytomegalovirus prophylaxis with ganciclovir: no guarantee for prevention of late serious manifestations of CMV after solid organ transplantation.

A 37-year-old woman presented with malaise, upper abdominal pain and fever seven months after renal transplantation. She was seronegative for cytomegalovirus (CMV) and had received a kidney from a seropositive donor. She had received CMV prophylaxis (oral ganciclovir) for three months after transplantation.

Serotonin syndrome and rhabdomyolysis in venlafaxine poisoning: a case report.

Newer, more selective, antidepressant agents are increasingly being used as first-line treatment. However, clinical experience in patients after a deliberate overdose is limited. We present a case of venlafaxine intoxication complicated by a late rise in creatine kinase, seizures and serotonin syndrome.

The kidney, a cardiovascular risk marker, and a new target for therapy.

Both reduced filtration power and increased excretion of albumin in the urine are powerful markers for renal and cardiovascular progressive function loss. These risk markers indicate the risk above and beyond the conventional existing risk markers/factors. The risk is substantial, because both reduced filtration and microalbuminuria are highly prevalent in the general population, matching in prevalence with the most well-known risk factor, hypertension.

Human anti-neutrophil cytoplasm autoantibodies to proteinase 3 (PR3-ANCA) bind to neutrophils.

Background: Recently, the in vivo pathogenic role of anti-neutrophil cytoplasm autoantibodies (ANCA) in ANCA-associated vasculitis has been challenged by Abdel-Salam et al. In their report, they observed that ANCA directed against proteinase 3 (PR3) cannot bind to their target autoantigen PR3 on circulating neutrophils (PMN). Here we present evidence that human PR3-ANCA do specifically bind to PMN that express PR3 on their membrane.

Ethical and practical issues regarding research in children: the European perspective.

Children, like all humans, are exposed to compounds in the environment and sometimes to drugs. The effect of this exposure cannot simply be deducted from studies in adults or animals. Effects might be different and even more dramatic than in adults due to the stage of growth and development of the infant.

Paroxysmal atrial fibrillation, quality of life and neuroticism.

Background: Paroxysmal atrial fibrillation (AF) is associated with significant impairment of quality of life (QoL), which is to a large extent independent of objective measures of disease severity. We sought to investigate the potential role of neuroticism in the impairment of QoL in patients with paroxysmal AF.

Methods: The study group (AF group) comprised 73 patients with paroxysmal AF (mean age 55.

Oral rehabilitation with dental implants in oligodontia patients.

Purpose: The aim of this retrospective report was to evaluate the treatment outcome of oral rehabilitation with dental implants in oligodontia patients.

Materials And Methods: Thirteen oligodontia patients treated with dental implants were examined clinically and radiographically (follow-up 3 +/- 2 years, range 1 to 8 years). In addition, patient-mediated concerns of satisfaction, treatment experience, and level of impairment of oral functions were assessed with questionnaires.

Causes of misdiagnosis and mistreatment of spinal tuberculosis with radiotherapy in nonendemic areas: a pitfall in diagnosis and treatment: hazards of radiotherapy on the tuberculous lesion.

Study Design: Report of initially misdiagnosed and mistreated cases.

Objectives: To report a previously undescribed misdiagnosis and subsequent mistreatment with radiation for tuberculosis of the spine and to promote awareness for tuberculosis in nonendemic areas.

Summary Of Background Data: It is not seldom that radiation therapy is provided for suspected malignant spinal lesions without histologic confirmation.

Increased incidence of brain metastases in cutaneous head and neck melanoma.

The incidence of cutaneous melanoma is increasing, and 10-20% of these melanomas are located in the head and neck region. The incidence of brain metastases, risk factors and outcome were analysed for melanomas originating in the head and neck region. During the period 1965-2000, 324 patients [152 females (47%), 172 males (53%)] were treated for cutaneous melanoma of the head and neck.

Radiation-induced sarcoma: a challenge for the surgeon.

Background: Treatment of radiation-induced sarcoma (RIS) remains an unsolved problem. To provide more insight into the disease process, its characteristics, outcome, and potential outcome determinants were defined.

Methods: From 1978 to 2003, 27 patients--20 females (74%) and 7 males (26%) with a median age 44 years (range, 1-73 years) at the time of diagnosis of the primary tumor--developed an RIS after a median interval of 8 years (range, 3-41 years).

Ultrasound to stimulate early bone formation in a distraction gap: a double blind randomised clinical pilot trial in the edentulous mandible.

Objective: In a double blind randomised clinical pilot trial, it was investigated whether low intensity pulsed ultrasound therapy stimulates early bone formation in a distraction gap created in a severely resorbed mandible.

Design: Eight patients underwent a mandibular vertical distraction over an average distance of 6.6+/-1.

Emotional and behavioural functioning of children of a parent diagnosed with cancer: a cross-informant perspective.

This study investigates emotional and behavioural problems in children of parents diagnosed with cancer and examines the relationship with demographic and illness-related variables. Furthermore, agreement and differences between informants regarding child's functioning were examined. Members of 186 families in which a parent had been diagnosed with cancer participated.

Abnormal endothelium-dependent microvascular reactivity in recently preeclamptic women.

Objective: To assess endothelial function at the level of skin microvasculature, using iontophoretic administration of acetylcholine (endothelium-dependent vasodilator) and sodium nitroprusside (endothelium-independent vasodilator), in women who recently had a preeclamptic pregnancy.

Methods: Microvascular skin reactivity was assessed by laser Doppler perfusion monitoring and iontophoresis of acetylcholine (ACh) and sodium nitroprusside (SNP) in 25 women with a history of early onset preeclampsia and 23 women with previous uncomplicated pregnancies, all of whom were between 3 and 11 months postpartum.

Results: Mean (+/- standard error of the mean) ACh-mediated vasodilatation, expressed as a percentage increase in flux, was higher in women who recently had a preeclampsia than in controls (535 +/- 46% versus 314 +/- 29%, P < .

Stridor and Horner's syndrome, weeks after attempted right subclavian vein cannulation.

A 23-year-old woman presented with renal failure resulting from polycystic kidney disease (PKD) aggravated by tubulo-interstitial nephritis. Emergency haemodialysis was planned, and cannulation of the right subclavian vein was attempted, but failed. During this procedure, inadvertent arterial puncture occurred.
