General practitioners base their clinical strategy on evidence-based medicine and experience. When prospective randomized controlled studies have not provided an answer to a specific clinical question, or when common practice in a certain area is not well established, guidelines formulated by specialists with in-depth knowledge of the field are needed. Studies have shown that gastroenterology guidelines have improved the approach to Helicobacter pylori infection and the management of gastroesophageal reflux disease. Failure to use these guidelines by general practitioners can lead to diagnostic inconsistencies and faulty patient care. This is particularly important in Israel, where the heterogeneous patient and physician populations are characterized by differences in the interpretation of symptoms, disease prevalence, and education.  相似文献

Diabetic eye complications, and particularly diabetic retinopathy, are the major cause of blindness in the working age groups of industrialized countries. Laser photocoagulation has been proven to reduce blindness due to retinopathy by at least 60 % but even more patients would benefit if treatment were delivered at an early enough stage. High-risk retinopathy, though, may not cause visual symptoms, and when the latter occur it is often too late to reverse them. Hence, a screening programme for diabetic retinopathy should aim at detecting patients at risk when they can still be effectively treated. This can be achieved by regularly checking the patients' eyes. The screening programme's target, as defined by the joint World Health Organization/International Diabetes Federation Saint Vincent Declaration Working Group, is to reduce diabetes-related blindness by one-third or more in the next 5 years. The number of individuals to be screened is high, 30000 per million total population per year, but available data indicate that this is feasible and that the initial investments in professional and material resources are more than justified by the reduction of preventable blindness and of the financial burdens that go with it. Indeed, prevention of the major cause of blindness in the working age group should rate the same priority as other widely deployed programmes, such as those to screen for cancer, neonatal hypothyroidism, and phenylketonuria. The concerted action of government health departments, patients' and professional associations will be vital for the successful implementation of this programme. The texts of this document (a protocol for the screening of diabetic retinopathy and cataract), Appendix 1 (information leaflet for the patients), and Appendix 2 (data collection card) were approved by 57 specialists, representing 30 diabetic and ophthalmic societies from 21 European countries, and endorsed for translation into all European languages and distribution at the appropriate levels.  相似文献

Patients undergoing surgery for malignancy are at increased risk of initial and recurrent venous thromboembolism (VTE). Several factors have been found to increase the risk of deep vein thrombosis (DVT) in cancer patients both during the first days after the operation and after discharge from hospital. Although, in general, thromboprophylaxis is provided to cancer patients after surgery, the length of time these patients require prophylaxis has not yet been established. Autopsy series, clinical series, and clinical trials indicate that up to about 40% of VTE occurs post discharge. General surgical patients undergoing major abdominal surgery require VTE prophylaxis, and prolonged thromboprophylaxis should be considered in the post-discharge period in high-risk patients, particularly those with cancer. Evidence from studies in general and orthopedic surgery show that prolonged prophylaxis reduces the number of thromboembolic events after discharge from hospital. Prophylaxis should be simple, safe, and effective and should be administered easily to allow continuation of therapy after discharge. Low-molecular-weight heparins are potentially the most suitable agents for long-term thromboprophylaxis in cancer patients.  相似文献

A new algorithm is proposed for the questioning of female subjects in screenings for angina of effort, that differs in certain respects from the anginal diagnosis algorithm using standard cardiologic questionnaire currently accepted in epidemiologic studies. The advantages of the modified questionnaire make it more suitable for the screening of female populations.  相似文献

Receptors for bitter, sugar, and other tastes have been identified in the fruit fly Drosophila melanogaster, while a broadly tuned receptor for the taste of acid has been elusive. Previous work showed that such a receptor was unlikely to be encoded by a gene within one of the two major families of taste receptors in Drosophila, the “gustatory receptors” and “ionotropic receptors.” Here, to identify the acid taste receptor, we tested the contributions of genes encoding proteins distantly related to the mammalian Otopertrin1 (OTOP1) proton channel that functions as a sour receptor in mice. RNA interference (RNAi) knockdown or mutation by CRISPR/Cas9 of one of the genes, Otopetrin-Like A (OtopLA), but not of the others (OtopLB or OtopLC) severely impaired the behavioral rejection to a sweet solution laced with high levels of HCl or carboxylic acids and greatly reduced acid-induced action potentials measured from taste hairs. An isoform of OtopLA that we isolated from the proboscis was sufficient to restore behavioral sensitivity and acid-induced action potential firing in OtopLA mutant flies. At lower concentrations, HCl was attractive to the flies, and this attraction was abolished in the OtopLA mutant. Cell type–specific rescue experiments showed that OtopLA functions in distinct subsets of gustatory receptor neurons for repulsion and attraction to high and low levels of protons, respectively. This work highlights a functional conservation of a sensory receptor in flies and mammals and shows that the same receptor can function in both appetitive and repulsive behaviors.

Humans possess the ability to distinguish among five basic tastes: sweet, bitter, salt, sour, and umami. Interestingly, there is considerable variety in the ability of other mammals to detect these qualities. For example, cats are missing sweet taste (1) and the bottlenose dolphin only detects salt in food (2). Yet the fruit fly, Drosophila melanogaster, responds to a similar repertoire of tastes as humans. This is all the more remarkable given the very distant evolutionary relatedness and the enormous differences in the anatomy of the fly and mammalian taste organs and points to a conserved function of these taste qualities in assessing food quality.Many of the receptors involved in Drosophila taste have been defined (3, 4). Those that contribute to sweet and bitter tastes have been characterized extensively and are members of the “gustatory receptor” (GR) family (3, 4). GRs are unrelated to the G protein–coupled receptors that function in mammalian sweet and bitter taste (3). Therefore, the abilities of insects and humans to respond to similar repertoires of chemicals such as sweet and bitter tastants have emerged independently.In mice, the taste of acids depends on a proton-selective channel, Otopetrin1 (OTOP1), which is expressed in type III taste receptor cells (57). OTOP1 was first identified based on its essential role in the vestibular systems of the mouse and zebrafish (811) and was found to encode a family of proton-selective ion channels functionally conserved from worms to humans (5, 9, 12). In sea urchins, an Otop channel functions in calcifying primary mesenchymal cells by promoting the removal of protons generated during the production of CaCO3 (13). Otop family members are structurally unrelated to other ion channels and are composed of 12 transmembrane segments (12, 14, 15), which assemble as a dimer with no obvious permeation pathway (14, 15). Flies, mice, and human genomes each contain three otop genes, although the fly genes are not direct homologs of the vertebrate genes (9).In Drosophila, low or moderate levels of some organic acids are attractive and promote feeding, while the same acids at higher concentrations repress food consumption (16, 17). This rejection contributes to survival as it discourages the animals from eating very acidic foods in the environment that can decrease lifespan. Two members of the large family of “ionotropic receptors” (IRs; IR25a and IR76b) function in GR neurons (GRNs) in the legs for sensing carboxylic acids and HCl (18). Mutation of either of these IRs disrupts the preference to lay eggs on acid-containing substrates (18). Flies prefer consuming lactic acid over water, and this preference is mildly reduced in Ir25a mutants (19).The receptors required for the gustatory rejection of noxious levels of acids have been largely enigmatic. An exception is IR7a, which is needed to suppress feeding on foods laced with acetic acid (17). IR7a is very narrowly tuned, as it does not impair the rejection of foods with HCl or any other carboxylic acid tested. This receptor acts in a subset of GRNs called B GRNs that are also activated by bitter chemicals and certain other aversive compounds (4, 17).Here, we identified a member of the family of Otop channels that in Drosophila is required for the detection of protons in food. Wild-type flies are strongly repelled by high levels of HCl and mildly attracted to a low level of HCl. We found that these responses depend on the Otopetrin-Like protein (OtopLA), which has a common evolutionarily origin with mammalian OTOP channels. By performing cell type–specific rescue experiments, we found that the strong repulsion and mild attraction to different levels of acids depends on expression of OtopLA in distinct subsets of GRNs.  相似文献

Summary On the basis of experiences gained in operations for biliary tract concretions carried out in 50 diabetic patients, the indications for cholecystectomy are established. The AA. consider timely cholecystectomy, even in cases of an asymptomatic course of cholelithiasis, because diabetic diseases of the biliary tract are more serious and more prone to complications. They observed improvement of the carbohydrate metabolism after the operations in cases where diabetes had been of a short duration (less than one year). The operation death rate did not differ from that of non-diabetics in the age group up to 60; in older patients the more unfavourable death rate was caused by vascular complications and by increased predisposition to infection.
Zusammenfassung Die Indikationen fuer die Cholezystektomie wurden bei 50 Diabetikern auf der Grundlage der eingeholten Erfahrungen bei Gallensteinentfernungen der Gallenwege gestellt. Die AA. halten die Cholezystektomie auch im Falle eines asymptomatischen Verlaufs der Cholelithiasis fuer angebracht, da die Gallenwegserkrankungen bei den Diabetikern sehr schwerer Natur sind und mehr zu Komplikationen neigen. Sie beobachteten eine Besserung des Kohlenhydratstoffwechsels nach dem Eingriff bei denjenigen Faellen, wo der Diabetes seit kurzer Zeit im Gange war (seit weniger als einem Jahr). Die Operationsmortalitaet unterschied sich in der Altersgruppe bis zu 60 Jahren nicht von der der nicht Diabetiker; bei den aelteren Patienten hingegen war die hoehere Mortalitaet den Gefässkomplikationen und der erhoehten Praedisposition gegenueber Infektionen zuzuschreiben.

Resumen Las indicaciones de la colecistectomía han sido establecidas en base a las experiencias recogidas en intervenciones de remoción de cálculos de las vías biliares en 50 diabéticos. Los AA. consideran oportuna la colecistectomía también en los casos de curso asintomático de la colelitiasis, dado que en los diabéticos las afecciones de las vías biliares son de carácter muy grave y están más propensas a las complicaciones. Los AA. han observado una mejoría en el metabolismo de los glúcidos después de la intervención, en los casos en los cuales el diabetes había tenido una duración breve (inferior a un año). La mortalidad operatoria no difería de la mortalidad en los no diabéticos en el grupo de edad hasta los 60 años, mientras que en los pacientes de edad más avanzada la más alta mortalidad era atribuible a las complicaciones vasculares y a la aumentada predisposición a las infecciones.

Resume On a déterminé les cas où la cholécystectomie est indiquée sur la base de l'expérience acquise au cours de l'exérèse de calculs des voies biliaires chez 50 diabétiques. Les AA. ont estimé que le recours à la cholécystectomie était opportun même en cas de décours asymptomatique de la cholélithiase, ceci parce que les affections des voies biliaires chez les diabétiques revêtent une forme très grave et ont plus tendance à entraîner des complications. Après l'intervention les AA. ont observé une amélioration du métabolisme glucidique pour les cas dans lesquels le diabète était très récent (moins d'un an). La mortalité opératoire a été semblable à celle des non diabétiques pour le groupe d'âge allant jusqu'à 60 ans, tandis que chez les patients plus âgés la plus forte mortalité a été attribuée aux complications vasculaires et à une prédisposition accrue aux infections.

Riassunto Le indicazioni per la colecistectomia sono state stabilite sulla base delle esperienze raccolte in interventi di rimozione di calcoli delle vie biliari in 50 diabetici. Gli AA. considerano opportuna la colecistectomia anche in caso di un decorso asintomatico della colelitiasi, poichè nei diabetici le affezioni delle vie biliari sono di natura molto grave e più inclini alle complicazioni. Essi hanno osservato un miglioramento del metabolismo glucidico dopo l'intervento nei casi in cui il diabete aveva avuto una breve durata (inferiore ad un anno). La mortalità operatoria non differiva dalla mortalità dei non diabetici nel gruppo d'età fino a 60 anni, mentre nei pazienti più anziani la più alta mortalità era riferibile alle complicanze vascolari ed all'aumentata predisposizione alle infezioni.

Because of changes in life expectancy, there is an increasing number of elderly patients with esophageal cancer. The aim of this study was to assess the outcome of esophagectomy for cancer in patients 80 years or older. A retrospective review was performed of the records of all patients who underwent esophagectomy for cancer from 1992 to 2007. A cardiac and pulmonary evaluation was obtained on an individual basis in the younger patients and in all octogenarians. Among 560 patients with esophagectomy for cancer, 47 patients (8%) were octogenarians. The median age of the younger group (n= 513) was 63 years (interquartile range 56–71). Octogenarians had significantly more stage III disease (49% vs 31%, P= 0.02) but received less neoadjuvant therapy than younger patients (2% vs 21%, P= 0.0004). In octogenarians, the transhiatal resection was more common than in the younger group (79% vs 36%, P < 0.0001). Weight loss prior to surgery was similar in both groups, but body mass index was significantly lower in octogenarians (25 vs 28 kg/m2, P= 0.0002). Major complications occurred in 26% in octogenarians and 31% in the younger group (P= 0.51). Hospital mortality was similar (9% for octogenarians vs 4% in the younger group, P= 0.13). The median postoperative hospital stay was similar at 16 days (P= 0.69). There was no difference in cancer‐related survival (median survival 48.9 vs 59.3 months, P= 0.31 log‐rank test). Esophagectomy can be performed safely in carefully selected octogenarians with good cardiac and pulmonary function. Patients should not be denied an esophagectomy based only on their age.  相似文献
