The impact of tinnitus on Dutch general practices: A retrospective study using routine healthcare data.

Purpose: Global prevalence of tinnitus (15%) is rising, indicating an increase in patients seeking help for this common symptom and potentially affecting the accessibility of care. The aim of this retrospective study is twofold; describing the morbidity trends and healthcare utilization among patients with recorded tinnitus at Dutch general practices (GP), and comparing overall healthcare utilization before and after tinnitus to similar patients without recorded tinnitus.

Patients And Methods: Routine electronic health records data from general practices participating in Nivel Primary Care Database were used to describe trends in age- and sex-specific incidence, contact prevalence and healthcare utilization (contacts, prescriptions, and referrals to secondary care) for tinnitus from 2012 to 2021.

Recruitment and retention of general practitioners in European medical deserts: a systematic review.

Introduction: Despite policies aiming at universal health coverage by ensuring availability and accessibility of general practitioners (GPs), medically underserved areas are still present in Europe. This systematic review aims to summarize and compare literature on interventions and their potential effectiveness of GP recruitment and retention in these underserved areas ('medical deserts') from 2011 onwards.

Methods: PubMed and Embase were used to identify publications, applying a two-stage selection process.

Patient education in chronic skin diseases: a systematic review.

The negative impact of skin disease on quality of life (QoL) has been described in many studies. Patient education as an adjunct to treatment, with the aim of improving QoL and reducing disease severity, is a relatively new technique in dermatology. The objective of this article is to analyse and summarise evidence concerning the effects of patient education on QoL and disease severity in patients with chronic skin diseases.

Cut-off values and significance of Oil Red O-positive cells in bronchoalveolar lavage fluid.

Objective: To evaluate the percentage and predictive value of Oil Red O-positive macrophages (ORO-PM) to identify lipid-laden macrophages in bronchoalveolar lavage fluids (BALF) from patients with different pathologies.

Methods: The percentage and absolute numbers of ORO-PM were evaluated in 305 BALF. The patients were separated into ten groups: corticosteroid treatment (n = 18), amiodarone treatment (n = 8), interstitial fibrosis (n = 11), human immunodeficiency virus (HIV)-positive (n = 25), infectious pneumonia (n = 43), severe haematological disorder (n = 25), interstitial syndrome (n = 109), suspicion of cancer (n = 17), transplant recipients (n = 50) and controls (n = 43).

Evaluation of the Epstein-Barr virus R-gene quantification kit in whole blood with different extraction methods and PCR platforms.

Reliable real-time quantitative PCR assays to measure Epstein-Barr virus (EBV) DNA load (EBV) are useful for monitoring EBV-associated diseases. We evaluated a new commercial kit, EBV R-gene Quantification kit (Argene, Varilhes, France) to quantify EBV DNA load in whole blood. Assay performance was assessed with two PCR platforms (LightCycler 2.

Evaluation of a commercial real-time PCR assay for quantitation of Epstein-Barr virus DNA in different groups of patients.

The aim of this study was to evaluate the performance of a molecular assay for quantitation of Epstein-Barr virus (EBV) DNA based on real-time PCR, and to determine EBV DNA levels in EDTA whole blood samples derived from different groups of patients. Following a manual DNA extraction protocol, real-time PCR was performed using the LightCycler EBV Quantification Kit, which demonstrated sufficient accuracy and linearity. Coefficients of variations were found to be between 6 and 42% and 5 and 34%, respectively, for inter-assay and intra-assay variations.

Evaluation of two computational models of amplitude modulation coding in the inferior colliculus.

Two computational models replicating amplitude-modulation encoding in the inferior colliculus (IC) are presented and compared. Neurons in this nucleus are modeled as point neurons using Mc Gregor equations, and receive depolarizing currents from action potentials delivered by stellate cells (chopper units) in the cochlear nucleus (CN). Stellate cells are modeled using modified Hodgkin-Huxley equations and receive inputs from a peripheral auditory model.

TrkC overexpression enhances survival and migration of neural stem cell transplants in the rat spinal cord.

Although CNS axons have the capacity to regenerate after spinal cord injury when provided with a permissive substrate, the lack of appropriate synaptic target sites for regenerating fibers may limit restoration of spinal circuitry. Studies in our laboratory are focused on utilizing neural stem cells to provide new synaptic target sites for regenerating spinal axons following injury. As an initial step, rat neural precursor cells genetically engineered to overexpress the tyrosine kinase C (trkC) neurotrophin receptor were transplanted into the intact rat spinal cord to evaluate their survival and differentiation.

A new method for encapsulation of living cells: preliminary results with PC12 cell line.

A new method is described for encapsulation of living cells. PC12 rat adrenal pheochromocytoma cells, which have been shown to synthesize, store and release dopamine were employed. The particles are made first and the cells then incorporated in a gentle mechanical procedure.

[Management of intractable cancer pain: from intrathecal morphine to cell allograft].

The durable effectiveness of intrathecal morphine administration is well established for the management of intractable cancer pain, after failure of systemic opioids, secondary to the persistence of non-reversible undesirable side effects. Many patients are referred to late in the disease course. This conservative method to control pain of malignant origin must not be reserved for last resort treatment for terminal patients.

[Clinical perspectives of xenografts: encapsulated chromaffin cells and pain].

Intrathecal allograft of chromaffin cells can be effectively used in replacement of more conventional therapies for treating intractable chronic pain, such as in cancer. The efficacy of this technique depends on the ability of those cells to produce analgesic opioids and on the immuno-privileged property of the central nervous system, in which rejection risks are limited. However, there are some limitations to the generalization of this new therapy, mainly due to the low number of available grafts.

Human chromaffin cell graft into the CSF for cancer pain management: a prospective phase II clinical study.

A number of pre-clinical studies have demonstrated the value of adrenal medullary allografts in the management of chronic pain. The present longitudinal survey studied 15 patients transplanted for intractable cancer pain after failure of systemic opioids due to the persistence of undesirable side-effects. Before inclusion, all the patients had their pain controlled by daily intrathecal (I-Th) morphine administration.

Adrenal medullary explants as an efficient tool for pain control: adhesive biomolecular components are involved in graft function ex vivo.

Adrenal medullary (AM) tissue transplantation into the central nervous system has been reported as a potential source of opioid peptides and catecholamines, which have analgesic effects useful in the control of chronic pain. Clinical trials, involving allogeneic graft of whole tissue explants into the subarachnoid space of the lumbar spinal cord, have already been reported. The aim of the present study was to determine whether adhesion and function of AM explants were related in some extent and how this relationship could account for improvement of AM tissue in terms of analgesic activity before grafting.

Intrathecal grafting of unencapsulated adrenal medullary tissue can bring CD4 T lymphocytes into CSF: a potentially deleterious event for the graft.

Adrenal medullary tissue including chromaffin cells was grafted intrathecally in cancer patients to relieve intractable pain. The central nervous system (CNS) is considered an immune privileged site. Therefore, non-HLA-matched and unencapsulated tissue was grafted in 15 patients and 1 sham control in a series of at least 20 grafts.

One-year chromaffin cell allograft survival in cancer patients with chronic pain: morphological and functional evidence.

The control of chronic pain through transplantation of chromaffin cells has been reported over the past few years. Analgesic effects are principally due to the production of opioid peptides and catecholamines by chromaffin cells. Clinical trials have been reported with allografts consisting of whole-tissue fragments implanted into the subarachnoid space of the lumbar spinal cord (14,19,36).

Relief of intractable cancer pain by human chromaffin cell transplants: experience at two medical centers.

In addition to its possible role as a replacement source in CNS degenerative diseases, neural transplantation may be used to augment the normal production of neuroactive substances. Our laboratory at the University of Illinois at Chicago has shown, in both acute and chronic pain models, that transplantation of adrenal medullary tissue or isolated chromaffin cells into CNS pain modulatory regions can reduce pain sensitivity in rodents. Chromaffin cells were chosen as the donor source since they produce high levels of both opioid peptides and catecholamines, substances which reduce pain sensitivity when injected locally into the spinal subarachnoid space.

Transplantation of human chromaffin cells for control of intractable cancer pain.

Adrenal medullary chromaffin cells produce high levels of endogenous opioid peptides. Recent data suggest that transplantation injected locally into the spinal subarachnoid space reduced intractable malignant pain. In order to determine the feasibility, the efficacy and the risks of using adrenal medullary tissue for control of irreducible pain, we have developed a transplantation protocol on cancer pain patients selected when they required chronic intrathecal injection of morphine and progressively increasing doses to maintain the level of analgesic effects.

Influence of a long duration exposure, 69 months, to the space flight factors in Artemia cysts, tobacco and rice seeds.

Three french laboratories have participated in the Free Flyer Biostack experiment. Artemia cysts, tobacco seeds and rice caryopsis and embryos were used. Biological objects in monolayers were dead.

Antibodies to bladder-tumor-associated antigens as prognosis probes in the flow-cytometric analysis.

Monoclonal antibodies directed against bladder tumor cells (10D1, 7C12, 6D1, 3C6, G4 and E7) and human leukocyte antigen (HLe1) were tested by flow cytometry on 68 bladder tumors involving 10 grade I, 29 grade II and 29 grade III tumors (WHO classification). According to their evolution stage, these tumors can be subdivided into 17 stage Pa, 34 stage P1, 7 stage P2 and 10 stage P3. Fifteen normal bladder samples were used as a control.
