The goal of this follow-up study was to assess the long-term survival of all patients having undergone a first PTCA between 1981 and 1990 and to relate the outcome to the baseline clinical and angiographic state. Although PTCA has become a widely accepted therapeutic choice for revascularization, the authors lacked information on long-term outcome. Data was collected by questionnaire, the end points being a second PTCA, MI, CABG, death or any of these events. The survival curves were constructed using the Kaplan-Meier method. Multivariate analysis was performed by a Cox proportional hazards model. Complete follow-up data were collected for 1,071 patients for a mean period of 7.4 years (SEM +/- 1.98 months) with a range of 0 to 14 years. Mean age was 57 years. PTCA was successful in 85% of patients. In-hospital event rates were death 1.3%, MI 4.4%, and emergency CABG 2.9%. Overall survival at 14 years was 69% (SEM +/- 9.6%) and event-free survival was 47% (SEM +/- 5.8%). MI rate was 11%, CABG 15%, and 20% of patients underwent repeat PTCA. Presence of cardiovascular risk factors, poor left ventricular ejection fraction, and prior CABG were significantly associated with poorer event-free survival. The short-term observations are consistent with results reported by the other follow-up studies. In addition, the study found a total survival rate 14 years after a first PTCA of 69% and 47% of the cohort remained event free.

BACKGROUND: The epidemiology of chest pain differs strongly between outpatient and emergency settings. In general practice, the most frequent cause is the chest wall pain. However, there is a lack of information about the characteristics of this syndrome. The aims of the study are to describe the clinical aspects of chest wall syndrome (CWS). METHODS: Prospective, observational, cohort study of patients attending 58 private practices over a five-week period from March to May 2001 with undifferentiated chest pain. During a one-year follow-up, questionnaires including detailed history and physical exam, were filled out at initial consultation, 3 and 12 months. The outcomes were: clinical characteristics associated with the CWS diagnosis and clinical evolution of the syndrome. RESULTS: Among 24 620 consultations, we observed 672 cases of chest pain and 300 (44.6%) patients had a diagnosis of chest wall syndrome. It affected all ages with a sex ratio of 1:1. History and sensibility to palpation were the keys for diagnosis. Pain was generally moderate, well localised, continuous or intermittent over a number of hours to days or weeks, and amplified by position or movement. The pain however, may be acute. Eighty-eight patients were affected at several painful sites, and 210 patients at a single site, most frequently in the midline or a left-sided site. Pain was a cause of anxiety and cardiac concern, especially when acute. CWS coexisted with coronary disease in 19 and neoplasm in 6. Outcome at one year was favourable even though CWS recurred in half of patients. CONCLUSION: CWS is common and benign, but leads to anxiety and recurred frequently. Because the majority of chest wall pain is left-sided, the possibility of coexistence with coronary disease needs careful consideration.

The glomus tumor is a rare, benign, but painful vascular neoplasm arising from the neuromyoarterial glomus. Primary intraosseous glomus tumor is even rarer, with only about 20 cases reported in the literature so far, 5 of which involved the spine. Surgical resection is currently considered the treatment of choice. We herewith present an uncommon case of primary intraosseous spinal glomus tumor involving the right pedicle of the eleventh thoracic vertebra (T11). To our knowledge, this is the first case of primary intraosseous spinal glomus tumor successfully treated by percutaneous CT-guided radiofrequency ablation (RFA).

RESUME : Introduction : L'objectif de cette étude est de déterminer l'influence de la dissection du palais lors de la chirurgie primaire et le type de chirurgie orthognathique requise chez les patients porteurs d'une séquelle de fente labio-maxillo-palatine unilatérale complète Méthode : Cette revue porte sur 58 enfants nés avec une fente labio-maxillo-palatine complète unilatérale et traités entre 1994 et 2008 à Page approprié pour une chirurgie orthognathique. C'est une étude rétrospective longitudinale mixte. Les patients avec des syndromes ou anomalies associées ont été exclus. Tous les patients ont été traités parle même orthodontiste et par la même équipe chirurgicale. Les enfants sont divisés en deux groupes; le premier comprend les patients avec une chirurgie primaire du palais conventionnelle, avec un décollement extensif de la fibro-muqueuse palatine. Le deuxième groupe comprend les patients opérés selon le protocole de Malek. Le palais mou est fermé a |'âge de trois mois, le palais dur à |'âge de six mois, avec un décollement minimal de la tibro-muqueuse palatine. Les radiographies du crâne de profil ainsi que les données chirurgicales ont été comparées. Résultats: La nécessité d'une chirurgie orthognathique est plus élevée dans le premier groupe par rapport au deuxième (60% versus 47,8%). Concernant le type de chirurgie orthognathique réalisé, des ostéotomies Lefort I en deux ou trois pièces ou des ostéotomies bi-maxillaires ont aussi été plus fréquentes dans le premier groupe Conclusion : La chirurgie primaire du palais selon le protocole de Malek améliore le pronostic des patients avec une fente labio-maxillo-palatine. Avec un décollement minimal de la fibro-muqueuse palatine, le nombre d'interventions de chirurgie orthognathique a été diminué. Lorsque ces opérations étaient néanmoins indiquées, elles étaient simplifiées.

OBJECTIVE: The goal of our study was to compare Doppler sonography and renal scintigraphy as tools for predicting the therapeutic response in patients after undergoing renal angioplasty. SUBJECTS AND METHODS. Seventy-four hypertensive patients underwent clinical examination, Doppler sonography, and renal scintigraphy before and after receiving captopril in preparation for renal revascularization. The patients were evaluated for the status of hypertension 3 months after the procedure. The predictive values of the findings of clinical examination, Doppler sonography, renal scintigraphy, and angiography were assessed. RESULTS: For prediction of a favorable therapeutic outcome, abnormal results from renal scintigraphy before and after captopril administration had a sensitivity of 58% and specificity of 57%. Findings of Doppler sonography had a sensitivity of 68% and specificity of 50% before captopril administration and a sensitivity of 81% and specificity of 32% after captopril administration. Significant predictors of a cure or reduction of hypertension after revascularization were low unilateral (p = 0.014) and bilateral resistive (p = 0.016) indexes on Doppler sonography before (p = 0.009) and after (p = 0.028) captopril administration. On multivariate analysis, the best predictors were a unilateral resistive index of less than 0.65 (odds ratio [OR] = 3.7) after captopril administration and a kidney longer than 93 mm (OR = 7.8). The two best combined criteria to predict the favorable therapeutic outcome were a bilateral resistive index of less than 0.75 before captopril administration combined with a unilateral resistive index of less than 0.70 after captopril administration (sensitivity, 76%; specificity, 58%) or a bilateral resistive index of less than 0.75 before captopril administration and a kidney measuring longer than 90 mm (sensitivity, 81%; specificity, 50%). CONCLUSION: Measurements of kidney length and unilateral and bilateral resistive indexes before and after captopril administration were useful in predicting the outcome after renal angioplasty. Renal scintigraphy had no significant predictive value.

This article reviews the methodology of the studies on drug utilization with particular emphasis on primary care. Population based studies of drug inappropriateness can be done with microdata from Health Electronic Records and e-prescriptions. Multilevel models estimate the influence of factors affecting the appropriateness of drug prescription at different hierarchical levels: patient, doctor, health care organization and regulatory environment. Work by the GIUMAP suggest that patient characteristics are the most important factor in the appropriateness of prescriptions with significant effects at the general practicioner level.

The Office of Transportation Data, in cooperation with the Federal Highway Administration, prepares this biennial traffic report. This report is used by federal, state, and local governmental agencies in determining highway needs, construction priorities, route location and environmental impact studies, and the application of appropriate design standards. The general public uses this information in determining the amount of traffic that passes a given area as they make their development plans and propose land use changes. The above reflects only a few of the many technical uses for this data.

An increasing proportion of new cancers is registered in patients who have received a previous cancer diagnosis. As data are inconsistent across studies, we provided information for populations long covered by valid cancer registration. Data were derived from the Swiss cancer Registries of Vaud and Neuchâtel (885 000 inhabitants). Patients diagnosed with a new malignancy (except skin basal and squamous cell carcinomas) during the period 2005-2010 were included. Over the period 2005-2010, 24 859 patients were registered with incident cancer. Of these, 3127 (13%) had multiple primary cancers and 578 (2.3%) were synchronous. Breast, prostate, colorectum, skin, melanomas, and squamous cell carcinomas of the head and neck (SHN) and bladder/ureter were the most common sites of first neoplasms, whereas breast, lung, colorectum, prostate, melanoma, and SHN were the most common sites of second neoplasms. The most common pairing was breast with breast (31% synchronous), followed by the bladder/ureter with the prostate (72% synchronous), prostate with the colorectum, SHN with SHN, and SHN with lung. Five-year crude survival of patients with synchronous cancers (34%) was not significantly lower than that of patients with single neoplasms (39%).

The study intended to understand the perception of nurses of Primary Care Services about the construction of ethical competence on their formation and practices. This is a qualitative study, with an interpretative phenomenological approach and interviews with ten nurses of the community health services of Porto Alegre, RS. The results showed that the interviewed professionals had already experienced situations with ethical conflicts and knew what ethical competence means. The central themes point out three fundamental issues in the construction of the ethical competence: personal values, education and practice. Taking into account that ethical competence is in permanent construction, the study shows the importance to promote organizational and educational activities in a transversal manner, as a tool to cope the moral stress and contribute in improving the quality of care in the primary health attention.

Objectives: To test if the time of day significantly influences the occurrence of type 4A myocardial infarction in elective patients undergoing percutaneous coronary intervention (PCI). Background: Recent studies have suggested an influence of circadian rhythms on myocardial infarction size and mortality among patients with ST-elevation myocardial infarction. The aim of the study is to investigate whether periprocedural myocardial infarction (PMI) is influenced by the time of day in elective patients undergoing PCI. Methods: All consecutive patients undergoing elective PCI between 2007 and 2011 at our institutions with known post-interventional troponin were retrospectively included. Patients (n = 1021) were divided into two groups according to the starting time of the PCI: the morning group (n = 651) between 07:00 and 11:59, and the afternoon group (n = 370) between 12:00 and 18:59. Baseline and procedural characteristics as well as clinical outcome defined as the occurrence of PMI were compared between groups. In order to limit selection bias, all analyses were equally performed in 308 pairs using propensity score (PS) matching. Results: In the overall population, the rate of PMI was statistically lower in the morning group compared to the afternoon group (20% vs. 30%, p < 0.001). This difference remained statistically significant after PS-matching (21% vs. 29%, p = 0.03). Multivariate analysis shows that being treated in the afternoon independently increases the risk for PMI with an odds ratio of 2.0 (95%CI: 1.1-3.4; p = 0.02). Conclusions: This observational PS-matched study suggests that the timing of an elective PCI influences the rate of PMI.

The radioactive concentrations of (166m)Ho, (134)Cs and (133)Ba solutions have been standardised using a 4πβ-4πγ coincidence counting system we have recently set up. The detection in the beta channel is performed using various geometries of a UPS-89 plastic scintillator optically coupled to a selected low-noise 1in. diameter photomultiplier tube. The light-tight thin capsule that encloses this beta detector is housed within the well of a 5in.×5in. NaI(Tl) monocrystal detector. The beta detection efficiency can be varied either by optical filtering or electronic discrimination when the electrons loose all their energy in the plastic scintillator. This 4πβ-4πγ coincidence system improves on our 4πβ(PC)-γ system in that its sample preparation is less labour intensive, it yields larger beta- and gamma-counting efficiencies thus enabling the standardisation of low activity sources with good statistics in reasonable time, and it makes standardising short-lived radionuclides easier. The resulting radioactive concentrations of (166m)Ho, (134)Cs and (133)Ba are found to agree with those measured with other primary measurement methods thus validating our 4πβ-4πγ coincidence counting system.
