Digestive tract metaplasia can be a precursor lesion regarding sinonasal digestive tract sort adenocarcinoma: genomic analysis of a scenario indicating this particular hypothesis.
Of the 23 studies, 16 used pharmacological interventions that improved bvFTD symptoms. Based on the Neuropsychiatric Inventory, trazodone had the greatest significant reductive effect on the symptoms of bvFTD. Overall, citalopram, rivastigmine, paroxetine, and trazodone all reduced multiple symptoms, including disinhibition, hyperorality, and depression. CONCLUSIONS This review provides an overview of the pharmacological interventions that can be used to treat the main bvFTD symptoms as well as a guideline for managing bvFTD. More research is needed to investigate the efficacy of pharmacological interventions for bvFTD through use of a validated outcome and a focus on the specific behavioral problems associated with bvFTD.Endometriosis is an estrogen-dependent inflammatory disease that affects approximately 10% of women. Debilitating pelvic or abdominal pain is one of its major clinical features. Current animal models of endometriosis-associated pain require surgery either to implant tissue or to remove the ovaries. Moreover, existing models do not induce spontaneous pain, which is the primary symptom of patients with chronic pain, including endometriosis. A lack of models that accurately recapitulate the disease phenotype must contribute to the high failure rate of clinical trials for analgesic drugs directed at chronic pain, including those for endometriosis. We set out to establish a murine model of endometriosis-associated pain. Endometriosis was induced non-surgically by injecting a dissociated uterine horn into a recipient mouse. The induced lesions exhibited histological features that resemble human lesions along with an increase in pro-inflammatory cytokines and recruitment of immune cells. We also observed the presence of CGRP-, TRPA1-, and TRPV1-expressing nerve fibers in the lesions. This model induced mechanical allodynia, spontaneous abdominal pain, and changes in thermal selection behavior that indicate discomfort. These behavioral changes were reduced by drugs used clinically for endometriosis, specifically letrozole (aromatase inhibitor) and danazol (androgen). Endometriosis also induced neuronal changes as evidenced by activation of the NF-κB signaling pathway in TRPA1- and TRPV1-expressing DRG neurons. In conclusion, we have established a model of endometriosis-associated pain that responds to clinically active drugs and can, therefore, be used to identify novel therapies.Previous studies have demonstrated that parental cognitive, behavioral, and emotional factors are related to child functioning in children and adolescents with chronic pain. This is particularly important to understand how to potentially enhance the efficacy of psychological interventions for children by incorporating interventions targeting parents. We conducted a systematic review and meta-analysis to identify the specific parent factors that have been examined in the literature and to quantify the associations observed between parent factors and child pain and disability. A search of the electronic databases EMBASE, PsychINFO, Medline, and PubMed was conducted, using search terms related to chronic pain, pediatric population, and parents. Fifty-four studies met criteria and were included in the review. Parent pain catastrophizing and protective behavior were the most commonly assessed parental constructs in the literature. Meta-analyses were conducted for associations between parent pain catastrophizing, parent protective behaviors, parent anxiety and depression, and parent stress associated with parenting a child with chronic pain with child pain, disability, school functioning, and emotional functioning. Correlation coefficients were pooled using the random-effects model. A medium relationship was observed between higher protective behavior and poorer school functioning (r = -0.39), and small relationships were found between higher parent pain catastrophizing and increased child disability (r = 0.29); higher protective behaviors and increased child disability (r = 0.25); and increased parent depression and anxiety with increased child disability (r = 0.23 and r = 0.24, respectively). Future research is needed to investigate broader parent variables and overcome methodological weaknesses in this field.Mutations in Nav1.9 encoded by SCN11A have been associated with episodic pain, small-fiber neuropathy and congenital insensitivity to pain. In this study, we collected and characterized one Chinese family with episodic pain. The SCN11A mutation (c.664C>A/p.Arg222Ser) was identified and cosegregated with the episodic pain phenotype. find more In addition, we found that alcohol intake triggered intense pain attacks and detected the ALDH2 polymorphism (c.1510G>A/p.Glu504Lys) in three patients with episodic pain. The alcohol-aggravated pain symptom and this ALDH2 polymorphism were also reconfirmed in our previously reported episodic pain patient with the Nav1.9 mutation (p.Ala808Gly, patient III-2 in HBBJ family). To assess the pathogenicity of the Nav1.9 mutation and the new trigger, we introduced a mutation (p.Ala796Gly) into the mouse (orthologous mutation in human is p.Ala808Gly). The alteration hyperpolarized channel activation, increased the residual current through non-inactivating channels, and induced hyperexcitability of dorsal root ganglion (DRG) neurons in Scn11a mice. The Scn11a mice showed increased sensitivity to mechanical, heat and cold stimuli, and hypersensitivity to acetaldehyde and formalin, which could account for the alcohol intake-induced pain phenotype in patients. Moreover, acetaldehyde increased the mutant mNav1.9 channel current and excitability of Scn11a mouse DRG neurons. Parecoxib (an anti-inflammatory medication) relieved the heat hypersensitivity in Scn11a mice not receiving inflammatory stimuli and significantly decreased the hyperexcitability of DRG neurons in Scn11a mice. These results indicated that Scn11a mice recapitulated many clinical features of patients and suggested that Nav1.9 channel contributes significantly to the inflammatory pain state.Low back pain (LBP) is a highly prevalent and disabling condition whose initiating factors are poorly understood. It is known that psychological and physical stress is associated with LBP but the causal relationship, mechanisms and mediators have not been elucidated, and a preclinical model enabling the investigation of causality and thereby critically contributing to clinical translation does not exist.In the present study, we first established and characterized a myofascial LBP model in mice based on NGF injection into the low back muscles. Secondly, we investigated the effect of two different stress paradigms on this mouse LBP model by applying the chronic unpredictable stress (CUS) and vertical chronic restraint stress (vCRS) paradigms, to mimic psychological and psychophysical stress, respectively. In these studies, we combined longitudinal behavioral tests with gene and protein expression analysis in the muscle, dorsal root ganglia and spinal cord. NGF-induced LBP was characterized by long-lasting local and plantar mechanical hypersensitivity, cold hyperalgesia, decreased grip strength and wheel running activity, and time-dependent changes of neuropeptide and glial markers in the spinal cord. link2 Interestingly, the exposure to CUS slightly worsened pain behavior, whereas vCRS primed and highly aggravated pain in this LBP model, by causing per se the intramuscular upregulation of endogenous NGF and increased spinal astrocyte expression.Our mouse model, particularly the combination of NGF injection and vCRS suggest that similar mechanisms are important in non-specific LBP and might help to investigate certain aspects of stress-induced exacerbation of pain.BACKGROUND AND OBJECTIVE To report the outcomes of topical difluprednate 0.05% use in the closure of full-thickness macular holes. PATIENTS AND METHODS Retrospective chart review of 4 patients with full-thickness macular holes who received difluprednate drops 4 times daily for a minimum of 12 weeks. Main outcome measures were macular hole status assessed with optical coherence tomography, visual acuity, intraocular pressure, and complications of treatment. RESULTS All patients had macular hole closure within 12 weeks of difluprednate exposure. Mean time to macular hole closure was 5 weeks (range, 2-12 weeks). Visual acuity improved with macular hole closure. Average baseline visual acuity was 20/42. Average visual acuity after macular hole closure was 20/26 (P = 0.14). Two patients experienced increased intraocular pressure with topical steroid use. link3 CONCLUSION Exposure to difluprednate in this cohort of patients with full-thickness macular holes was associated with reduced macular edema, macular hole closure, and visual improvement.Patient engagement technologies have become a focal point for defining quality in government and medical practice arenas. Patient portals are recognized as a promising mechanism to foster patient engagement and, as such, have become embedded in major healthcare reform initiatives. Despite sweeping implementation endeavors, portal adoption rates among patients remain low and create a significant gap in quality-based reimbursement. The purpose of this research was to evaluate a 12-week portal adoption program in the primary care setting featuring customized tablets with a patient-centric design for targeted point-of-contact portal registration. This project focused on three objectives (1) achieve a 75% metric for portal adoption to align with highest tier adopters; (2) evaluate patient satisfaction for measuring perceived ease-of-use and usefulness of system; and (3) assess cost-effectiveness in determining sustainability and potential to replicate the initiative throughout other primary care settings. An outcome evaluation of the program revealed a 90% portal utilization rate, 94% new patient portal adoption rate, and 79% existing patient portal adoption rate during the data collection period. A χ analysis revealed a statistically significant difference in patient satisfaction scoring relative to efficiency, quality of care, and safety of information based on sex and insurance carrier demographics.PURPOSE OF REVIEW Crescents are classical histopathological lesions found in severe forms of rapidly progressive glomerulonephritis, also referred to as crescentic glomerulonephritis (CGN). Crescent formation is a consequence of diverse upstream pathomechanisms and unraveling these mechanisms is of great interest for improving the management of patients affected by CGN. Thus, in this review, we provide an update on the latest insight into the understanding on how crescents develop and how they resolve. RECENT FINDINGS Cellular crescents develop from activated parietal epithelial cells (PECs) residing along Bowman's capsule and their formation has as a consequence the decline in glomerular filtration rate (GFR). Cellular crescents can be reversible, but when multilevel growth of PECs associate with an epithelial--mesenchymal transition-like change in cell phenotype, fibrous crescents form, and crescents become irreversible also in terms of GFR recovery. Different molecular pathways trigger the activation of PECs and are a prime therapeutics target in CGN. First, crescent formation requires also vascular injury causing ruptures in the glomerular basement membrane that trigger plasmatic coagulation within Bowman's space. This vascular necrosis can be triggered by different upstream mechanisms, such as small vessel vasculitides, immune complex glomerulonephritis, anti-GBM disease, and C3 glomerulonephritis, that all share complement activation but involve diverse upstream immune mechanisms outside the kidney accessible for therapeutic intervention. SUMMARY Knowing the upstream mechanisms that triggered crescent formation provides a tool for the development of therapeutic interventions for CGN.
