PurposePediatric gastrostomy tubes (G-tubes) are associated with considerable utilization of healthcare resources. G-tube dislodgement can result in tract disruption and abdominal sepsis. We aimed to reduce early G-tube dislodgement by 25%.MethodsAn interdisciplinary team convened to identify key drivers of G-tube dislodgement and implement initiatives to reduce this complication. A G-tube care bundle was implemented in 2018. Rates of early G-tube dislodgement (within 90 days of insertion) were tracked. 15 months of cases after bundle implementation were compared to 20 months of cases before implementation. Length of stay (LOS, balancing measure) and bundle compliance (process measure) were tracked.ResultsG-tube dislodgements decreased 47% after bundle implementation. Overall, dislodgements after G-tube insertion decreased from 43% to 19% dislodgements per tube inserted, p = 0.004. Reductions were observed for dislodgements occurring in both the inpatient (14% vs. 1.5%) and outpatient (29% vs. 18%) settings. Median LOS was reduced from 15.3 to 7.1 days following implementation, p = 0.004. Process measures demonstrated 75% or greater compliance one year after implementation.ConclusionAn interdisciplinary team using quality improvement science methodology can significantly reduce G-tube dislodgement and improve value after pediatric gastrostomy tube insertion.Type of studyLongitudinal cohort study.Level of evidenceIII.  相似文献

Background: Telemedicine is an evolving tool to increase patients’ access to subspecialty care. Since 2014, Arkansas has been utilizing telemedicine in the evaluation of patients with hand injuries. The purpose of this study is to assess the effect of this novel telemedicine system for the management of hand trauma on patient transfer. Methods: We reviewed data from the first year of the telemedicine program (2014) and compared it to data from the year prior (2013). Data collection from both years included number of hand consults and need for transfer. From the 2014 data, we also recorded the use of telemedicine, type of transfer, distance of transfer, and time to disposition. Results: During 2013 (pre-telemedicine), there were 263 hand traumas identified. In all, 191 (73%) injuries required transfer to a higher level of care, while 72 (23%) were managed locally. In the first year of the telemedicine program (2014), a total of 331 hand injuries were identified. A total of 298 (90%) resulted in telemedicine consultation with 65% (195) utilizing video encounters. After telemedicine consultation, local management was recommended for 164 injuries (55%) while transfer was recommended for 134 (45%). Using telemedicine, there was a significant decrease in the percentage of transfer for hand injuries (P < .001). Conclusions: The telemedicine program was well utilized and provided patients throughout the state with continuous access to fellowship trained hand surgeons including regions where hand subspecialty care is not available. The program resulted in a significant decrease in the number of hospital transfers for the management of acute hand trauma.  相似文献

We recently described the cloning of a fifth member of the 5-hydroxytryptamine (5-HT)1 (serotonin1) receptor class that inhibits adenylyl cyclase, namely the human 5-HT1F receptor (Adham et al. 1993 a). In the present study we have examined in greater detail the functional coupling of the 5-HT1F receptor in two different cell lines, NIH-3T3 and LM(tk) fibroblasts (receptor densities of 1.7 and 4.4 pmol/mg protein, respectively). The maximal inhibitory response elicited by 5-HT was significantly greater in NIH-3T3 as compared to LM(tk) cells, whereas the EC50 values were comparable.To investigate the relationship between receptor occupancy and inhibition of cAMP accumulation mediated by 5-HT1F receptors in NIH-3T3 cells (and hence the degree of receptor reserve), we used the irreversible receptor antagonist N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ). The half-maximal response required only about 10% receptor occupancy, consistent with a receptor reserve of 90% (88±2.1%, n = 4) for 5-HT-induced inhibition of FSCA. Despite the presence of such a high degree of receptor reserve, a range of intrinsic activities was displayed by structurally diverse classes of compounds. For example, sumatriptan and lysergol were as efficacious as 5-HT itself and thus acted as full agonists, whereas metergoline and 1-NP behaved as partial agonists and as shown previously (Adham et al. 1993a), methiothepin was a silent antagonist (Kb = 438 nM).We have also investigated activation of additional signal transduction pathways by the 5-HT1F receptor and found that the responses differ in the two cell lines with respect to stimulation of phospholipase C. For example, in NIH-3T3 cells no elevation of inositol phosphates (IP) of [Ca2+]i was observed even at very high agonist concentrations (100 M). In contrast, in LM(tk) cells concentrations of 5-HT as low as 10 nM induced stimulation of IP and a rapid increase of [Ca2+]i. The 5-HT1F receptor failed to alter arachidonic acid release in either cell line.The maximal increase in IP accumulation in LM(tk) cells was modest, averaging about 100% above basal. The increases of IP and [Ca2+]i required 5-HT concentrations less than one order of magnitude greater than those inhibiting FSCA (EC50 = 17, 55 and 8 nM, respectively), and both responses were blocked by 100 M methiothepin. All three responses (cAMP, IP, and [Ca2+]i) were sensitive to pertussis toxin pre-treatment, suggesting the involvement of Gi/Go protein(s) in these signal transduction pathways. [Ca2+]i was also elevated by sumatriptan, which may provide a mechanism by which this drug causes constriction of the vasculature. In conclusion, these data indicate that the human 5-HT1F receptor can couple to multiple effectors, and that this coupling is cell-type dependent.Abbreviations FSCA forskolin-stimulated cAMP accumulation - [Ca2+] intracellular free calcium concentration - AA arachidonic acid - EEDQ N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline - CHO chinese hamster ovary cell - LM(tk) mouse fibroblast cell - Bmax maximal binding site density - Ki apparent dissociation constant obtained from competition binding studies - G protein guanine nucleotide-binding protein - HBS HEPES-buffered saline - IP inositol phosphates - IP3 inositol 1,4,5 trisphosphate - PLC phospholipase C - Kb antagonist dissociation constant - Kd equilibrium dissociation constant - N-1F-6 stable NIH-3T3 cells expressing the cloned 5-HT1F receptor - L-1F-3 stable LM(tk) cells expressing the cloned 5-HT1F receptor - PTX pertussis toxin - BSA bovine serum albumin - METH methiothepin - SUMA sumatriptan - 5-MeO-DMT 5-methoxy-N,N-dimethyltryptamine - 1-NP 1-(1-napthyl)piperazine - 5-CT 5-carboxyamidotryptamine Correspondence to: N.

Hereditary breast cancer (HBC) shows extant clinical and genetic heterogeneity. Clinically one finds the onset of breast cancer at an early age, an excess of bilaterality, and patterns of multiple primary cancer such as combinations of breast and ovarian carcinoma in the hereditary breast-ovarian cancer (HBOC) syndrome. In addition to HBOC, one sees a variety of putative breast cancer-prone genotypes inclusive of hereditary site-specific breast cancer, and the Li-Frameni (SBLA) syndrome that is characterized by cancers involving all three germinal layers including sarcomas, brain tumors, leukemia, lymphoma, and adrenal cortical carcinoma in addition to often markedly early-onset breast cancer. Breast cancer is also associated with autosomal dominantly inherited Cowden's disease and autosomal recessively inherited ataxia-telangiectasia. Examples of pedigrees depicting clincal examples of these several HBC syndromes are presented in order to describe HBC's heterogeneity. The recent identification of the BRCA1 gene in early-onset hereditary sitespecific breast cancer and the HBOC syndrome has led to new challenges for the genetic counselor. We review genetic counseling, which embraces surveillance and management recommendations that are responsive to the natural history of HBC and address the concept for future development of centers of expertise for HBC in the interest of improving cancer control.
Resumen El cáncer mamario hereditario (CMH) exhibe una gran heterogeneidad clínica y genética. Desde el punto de vista clínico, se observa el comienzo del cáncer mamario en una edad temprana, una tasa considerable de bilateralidad, y patrones de múltiples cánceres primarios, tal como la combinación de carcinomas mamario y ovárico en el síndrome del cáncer de seno-ovario hereditarios (CSOH). Además del CSOH, se puede observar una variedad de genotipos putativos propensos al cáncer, incluyendo el cáncer mamario hereditario de ubicación específica y el síndrome de Li-Fraumeni, que se caracteriza por cánceres que afectan a todas las tres capas germinales, incluyendo sarcomas, tumores cerebrales, leucemia, linfoma y carcinoma adrenocortical, además de un notorio comienzo precoz del cáncer mamario. El cáncer mamario también se asocia con la enfermedad de Cowden hereditaria y autosómica dominante y con la ataxia-telangiectasia autosómicamente recesiva. Se presentan ejemplos de pedigríes que ilustran diversos síndromes de CMH, con el objeto de demostrar la heterogeneidad del CMH. La reciente identificación del gen BRCA1 en el cáncer mamario hereditario, de ubicación específica y de comienzo temprano, y el sindrome CSOH, ha significado nuevos desafíos para el consejero genético. En este artículo hacemos una revisión de la consejería genética que se refiere a la vigilancia y a las recomendaciones sobre manejo que corresponda a la historia natural del CMH, y enfocamos el concepto en cuanto al desarrollo de centros de especializados en CMH, con el propósito de mejorar el control del cáncer.

Résumé Le cancer du sein héréditaire (CSH) est cliniquement et génétiquement hétérogène. au point de vue clinique, le cancer dbute habituellement à un âge jeune, est souvent bilatéral, et est parfois associé à d'autres cancers primitifs, comme par exemple dans le syndrome de cancer héréditaire du sein et de l'ovaire (SCO). On peut également observer d'autres génotypes présumés susceptibles de donner des cancers du sein héréditaires ainsi que le syndrome Li-Fraumeni (SBLA), caractérisé par l'envahissement des trois couches germinales et comprenant les tumeurs sarcomateuses, les tumeurs du cerveau, les leucémies, les lymphomes, et des cancers des corticosurrénales associées à des cancers du sein à un âge précoce. Le cancer du sein est parfois associé à la maladie de Cowden, une maladie autosomique dominante, et la télangiectasie ataxique, une maladie autosomique récessive. Des exemples de pedigrees de plusieurs types des CSH sont présentés, soulignant l'hétérogénéité de ce syndrome. La plus récente identification du gène BRCA1 et son rôle dans le cancer du sein et le syndrome HBOC est un nouveau challenge pour le généticien d'aujourd'hui. Nous passons en revue nos attitudes de conseil génétique comprenant à la fois les recommandations de surveillance nouveau challenge pour le généticien d'aujourd'hui. Nous passons en revue nos attitudes de conseil génétique comprenant à la fois les recommandations de surveillance et d'attitude thérapeutiques compatibles avec l'histoire naturelle des CSH, et qui ont trait au développement future des Centres spécialisés pour évaluer ces CSH dans le but l'améliorer leur contrôle.

Widespread use of prophylactic colectomy has resulted in a reduction in the incidence of colorectal cancer in familial adenomatous polyposis (FAP) patients. A retrospective chart review of families registered at the Steve Atanas Stavro Familial Gastrointestinal Cancer Registry in Toronto was performed to determine whether the decrease in the number of patients developing colorectal cancer implies that causes of mortality in FAP patients are shifting to that of extracolonic manifestations of FAP. Information was available on 140 deaths within 158 families and among 461 individuals with FAP. When stratified by decade, from the 1930s to the 1990s, the ratio of deaths caused by extracolonic manifestations of FAP compared with deaths caused by colorectal cancer was noted to have risen. Even though most deaths in FAP patients are still from colorectal cancer, it appears that screening policies and prophylactic colectomy have resulted in a reduction in the number of FAP patients who develop colorectal cancer. Thus, in recent decades, a greater percentage of deaths in FAP patients appears to be attributable to extracolonic manifestations of the disease.  相似文献
