[Flexible programs and advanced training for rheumatological patient education].

In two research projects, rheumatological patient education programmes were updated. The first step was to develop an expert consented framework for all rheumatological patient education programmes. From this, curricula and working materials for rheumatoid arthritis (RA) and axial spondyloarthritis (AS) were derived and two exemplary patient education manuals developed.

[Multimorbidity in elderly rheumatic patients part 2].

While diseases, such as cardiovascular diseases and osteoporosis in the elderly are categorized as comorbidities of rheumatoid arthritis, elderly rheumatic patients are often additionally affected by thyroid dysfunctions and diabetes mellitus type 2, so that the risk of multimorbidity (coexistence of at least two chronic and/or acute diseases) will increase significantly in elderly patients already suffering from systemic rheumatic diseases. Restricted cognition, adherence or compliance may additionally complicate the treatment of elderly rheumatic patients. Furthermore, the pharmacokinetics of the elderly is another challenging task.

[Multimorbidity in elderly rheumatic patients part 1].

An appropriate treatment of elderly rheumatic patients implements comprehensive diagnostics and exclusion diagnostics of e.g. coronary heart disease, osteoporosis, renal failure, diabetes mellitus type 2 and thyroid gland dysfunction.

Acute effects of short-chain alkylglycerols on blood-brain barrier properties of cultured brain endothelial cells.

Background And Purpose: The blood-brain barrier (BBB) restricts drug penetration to the brain preventing effective treatment of patients suffering from brain tumours. Intra-arterial injection of short-chain alkylglycerols (AGs) opens the BBB and increases delivery of molecules to rodent brain parenchyma in vivo. The mechanism underlying AG-mediated modification of BBB permeability is still unknown.

Effects of 18-kDa translocator protein knockdown on gene expression of glutamate receptors, transporters, and metabolism, and on cell viability affected by glutamate.

Objective: Previously, several important roles for glutamate have been described for the biology of primary brain tumors. For example, glutamate has been suggested to promote glioma cell proliferation by the activation of the 2-amino-3-(5-methyl-3-oxo-1,2-oxazol-4-yl)propanoic acid (AMPA) subtype of glutamate receptors. In the present study, we determined the potential regulatory roles of the 18-kDa translocator protein (TSPO) in the glutamatergic system in relation to cell death of brain tumor cells through knockdown of the TSPO by genetic manipulation.

The 18 kDa translocator protein influences angiogenesis, as well as aggressiveness, adhesion, migration, and proliferation of glioblastoma cells.

Background: It is known that the mitochondrial 18 kDa translocator protein (TSPO) is present in almost all peripheral tissues and also in glial cells in the brain. TSPO levels are typically enhanced in correlation with tumorigenesis of cancer cells including glioblastoma. Relevant for angiogenesis, TSPO is also present in almost all cells of the cardiovascular system.

Antibody levels against tetanus and diphtheria after polychemotherapy for childhood sarcoma: a report from the Late Effects Surveillance System.

Background: It is known that antineoplastic treatment may induce secondary immunodeficiency, but studies after childhood sarcoma are rare. Since 1998, the Late Effects Surveillance System (LESS) of the German Society for Paediatric Oncology and Haematology (GPOH) prospectively registers late effects in soft tissue-, osteo- and Ewing's sarcoma patients treated within the therapy trials EICESS-92/EURO-E.W.

Hyperkalemia complicating propranolol treatment of an infantile hemangioma.

Propranolol treatment was recently reported to be successful for the management of severe infantile hemangioma. Known adverse effects of propranolol treatment include transient bradycardia, hypotension, hypoglycemia, and bronchospasm (in patients with underlying spastic respiratory illnesses), which led to a general recommendation to gradually increase propranolol dosage and closely monitor patients' hemodynamics at the onset of therapy. To date, no serious or unexpected adverse effects that required specific intervention have been reported.

Favourable outcome of patients with childhood acute promyelocytic leukaemia after treatment with reduced cumulative anthracycline doses.

Acute promyelocytic leukaemia (APL) treatment often includes high cumulative doses of anthracyclines, which can cause long-term cardiotoxicity. Here, we report the favourable outcome in 81 paediatric APL patients treated according to the consecutive acute myeloid leukaemia-Berlin/Frankfurt/Muenster (AML-BFM) trials -93/-98/-2004 with an anthracycline-cytarabine regimen in combination with all-trans-retinoid acid (ATRA). Outcomes achieved by treatment with a reduced cumulative anthracycline dose (350 mg/m(2)) were comparable to those reported for studies with higher doses.

Potential involvement of F0F1-ATP(synth)ase and reactive oxygen species in apoptosis induction by the antineoplastic agent erucylphosphohomocholine in glioblastoma cell lines : a mechanism for induction of apoptosis via the 18 kDa mitochondrial translocator protein.

Erucylphosphohomocholine (ErPC3, Erufosine) was reported previously to induce apoptosis in otherwise highly apoptosis-resistant malignant glioma cell lines while sparing their non-tumorigenic counterparts. We also previously found that the mitochondrial 18 kDa Translocator Protein (TSPO) is required for apoptosis induction by ErPC3. These previous studies also suggested involvement of reactive oxygen species (ROS).

Zygomycosis in a 13 year old girl with T-NHL.

We report the clinical and pathological findings of an unusual invasive fungal infection in a 13-year-old girl with T-NHL. The diagnosis of disseminated Zygomycosis was made four days after onset of clinical symptoms. Risk factors for Zygomycosis were prolonged neutropenia, corticosteroids, and steroid induced diabetes mellitus.

Poor outcome for children and adolescents with progressive disease or relapse of lymphoblastic lymphoma: a report from the berlin-frankfurt-muenster group.

Purpose: Little is known about the outcome of pediatric patients with lymphoblastic lymphoma (LBL) who suffer from progressive disease or relapse.

Patients And Methods: We analyzed the pattern of LBL relapses after current non-Hodgkin's lymphoma Berlin-Frankfurt-Muenster (BFM) frontline therapy between April 1990 and March 2003. Relapse therapy was according to acute lymphoblastic leukemia (ALL) -Relapse-BFM protocols or ALL-BFM protocols for high-risk patients.

Inhibitor-Immunology-Study. Different HLA-types seem to be involved in the inhibitor development in haemophilia A.

Unlabelled: The development of inhibitors is one of the most important complications of replacement therapy in haemophilia, affecting mortality and morbidity. Inhibitor development is based on complex immunological factors. Cytokines and their receptors, T-cell receptors, and the Major Histocompatibility Complex may play important roles in the development of inhibitors.

Ligands of the mitochondrial 18 kDa translocator protein attenuate apoptosis of human glioblastoma cells exposed to erucylphosphohomocholine.

Background: We have previously shown that the anti-neoplastic agent erucylphosphohomocholine (ErPC3) requires the mitochondrial 18 kDa Translocator protein (TSPO), formerly known as the peripheral-type benzodiazepine receptor (PBR), to induce cell death via the mitochondrial apoptosis pathway.

Methods: With the aid of the dye JC-1 and cyclosporin A, applied to glioblastoma cells, we now investigated the significance of opening of the mitochondrial permeability transition pore (MPTP) for ErPC3-induced apoptosis in interaction with the TSPO ligands, PK 11195 and Ro5 4864. Furthermore, we measured cytochrome c release, and caspase-9 and -3 activation in this paradigm.

[Risk factors for perioperative complications in renal surgery for Wilms' tumor].

Background: There is controversy about preoperative chemotherapy in the treatment of Wilms' tumor. The perioperative morbidity plays a key role in this discussion. Therefore, risk factors of perioperative complications were analysed in our series of patients with Wilms' tumor with a special focus on the effects of preoperative chemotherapy.

[Fibromyalgia. Diagnostics--disease approach--therapy].

Fibromyalgia is a complex of symptoms predominantly affecting females and consisting of widespread pain. Etiology and pathogenesis are not sufficiently known yet, however, there is the assumption that fibromyalgia is looked at as being an illness with biological, psychological, and social aspects. Therefore, the treatment of fibromyalgia calls for a multimodal therapy approach.

Downregulation of Apaf-1 and caspase-3 by RNA interference in human glioma cells: consequences for erucylphosphocholine-induced apoptosis.

Erucylphosphocholine (ErPC) exerts strong anticancer activity in vivo and in vitroand induces apoptosis even in chemoresistant glioma cell lines. We investigated the contribution of Apaf-1 and caspase-3 to the apoptotic response to ErPC using RNA interference (RNAi) in human glioblastoma cells. We could demonstrate that human glioma cell lines are susceptible to RNAi.

The peripheral-type benzodiazepine receptor and tumorigenicity: isoquinoline binding protein (IBP) antisense knockdown in the C6 glioma cell line.

Peripheral-type benzodiazepine receptors (PBR) are constituted by three protein components, the isoquinoline binding protein (IBP), the voltage-dependent anion channel (VDAC), and the adenine nucleotide transporter (ANT). Recently, we found that high levels of PBR ligand binding in glioma cell lines correlate with in vitro tumorigenicity. To study whether enhanced PBR expression is causative or in response to cancer, we genetically modified C6 glioma cells.

Low occurrence of familial neuroblastomas and ganglioneuromas in five consecutive GPOH neuroblastoma treatment studies.

Familial neuroblastoma is of special interest in view of the oncogenesis of this tumour with its early manifestation in childhood. The inheritance seems to follow an autosomal-dominant mendelian trait with incomplete penetrance. Familial neuroblastomas and ganglioneuromas have not been reported in detail within large treatment studies.
