Patient Management (patient + management)
Selected AbstractsToward a predictive model of patient satisfaction with nurse practitioner careJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2005A/G/FNP, Ann Green PhD Purpose (a) To determine if caring behaviors of nurse practitioners (NPs), gender of NPs, setting (urban or rural), and age, gender, ethnicity, education, and income of patients were predictors of patient satisfaction; (b) to determine which of these characteristics was the best predictor(s) of patient satisfaction; and (c) begin to develop a conceptual model for explaining patient satisfaction with NP care. Data sources Responses to the Caring Behaviors Inventory (CBI) and a demographic inquiry by 348 NPs in Louisiana and completion of the Di'Tomasso,Willard Patient Satisfaction Questionnaire (DWPSQ) and a demographic inquiry from 817 patients in Louisiana served as data sources. A predictive modeling design explored which variable(s) is the best predictor of patient satisfaction, and multiple regression was used to determine the equation for the best-fitting line and the optimal model for the best predictor(s) of patient satisfaction. Conclusions CBI mean scores were high for all NPs. No statistically significant difference was found between male NPs' and female NPs' total mean CBI scores and between urban or rural total mean CBI scores. DWPSQ mean scores and subscale scores indicated high satisfaction with NP care. No statistically significant relationships were found between the NPs' CBI mean scores and the patients' DWPSQ mean scores. There were significant relationships between the DWPSQ subscales, including Wait Time and Patient Management. Stepwise linear regression revealed that patients' age group was a predictor of DWPSQ total mean scores. Implications for practice NPs need to be aware of developmental differences in all age groups and the differences in perceptions of care. There are many variables to consider when determining patient satisfaction with care, including the patients' sociodemographic and health variables, the healthcare system, and characteristics of the healthcare providers. Awareness of these variables may affect how NPs deliver care and ensure quality care with which the patients are satisfied. [source] Protocol Biopsies in Renal Transplantation: Insights into Patient Management and PathogenesisAMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2007M. Mengel A 1-day symposium on the application of protocol biopsies in renal transplantation was held in Boston, 21 July 2006. Representatives from centers with extensive experience in the use of protocol biopsies for routine patient care and research reported results on the pathological findings and their value in patient management. The consensus was that protocol biopsies, in experienced hands, are a safe and valuable means of detecting subclinical disease that can benefit from modification of therapy. Furthermore, molecular studies reveal evidence of activity or progression not readily appreciated by histological techniques. Wider application is expected in multicenter clinical trials to predict and validate outcomes. The principal barrier to wider use of protocol biopsies is knowledge of the benefits of intervention. [source] Patients Presenting to the Emergency Department With Non-specific Complaints: The Basel Non-specific Complaints (BANC) StudyACADEMIC EMERGENCY MEDICINE, Issue 3 2010Marek Nemec MD Abstract Objectives:, Patient management in emergency departments (EDs) is often based on management protocols developed for specific complaints like dyspnea, chest pain, or syncope. To the best of our knowledge, to date no protocols exist for patients with nonspecific complaints (NSCs) such as "weakness,""dizziness," or "feeling unwell." The objectives of this study were to provide a framework for research and a description of patients with NSCs presenting to EDs. Methods:, Nonspecific complaints were defined as the entity of complaints not part of the set of specific complaints for which evidence-based management protocols for emergency physicians (EPs) exist. "Serious conditions" were defined as potentially life-threatening or those requiring early intervention to prevent health status deterioration. During a 6-month period, all adult nontrauma patients with an Emergency Severity Index (ESI) of 2 or 3 were prospectively enrolled, and serious conditions were identified within a 30-day period. Results:, The authors screened 18,261 patients for inclusion. A total of 218 of 1,611 (13.5%) nontrauma ESI 2 and 3 patients presented with NSCs. Median age was 82 years (interquartile range [IQR] = 72 to 87), and 24 of 218 (11%) were nursing home inhabitants. A median of 4 (IQR = 3 to 5) comorbidities were recorded, most often chronic hypertension, coronary artery disease, and dementia. During the 30-day follow-up period a serious condition was diagnosed in 128 of 218 patients (59%). The 30-day mortality rate was 6%. Conclusions:, Patients with NSC presenting to the ED are at high risk of suffering from serious conditions. Sensitive risk stratification tools are needed to identify patients with potentially adverse health outcomes.

Design 180 third and fourth year Leicester medical students were directly observed consulting with six general practice patients and independently assessed by a pair of assessors. A total of 70 practice and 16 departmental assessors took part. Performance scores were subjected to generalizability analysis and students' views of the assessment were gathered by questionnaire. Results Four of the five categories of consultation performance (Interviewing and history taking, Patient management, Problem solving and Behaviour and relationship with patients) were assessed in over 99% of consultations and Physical examination was assessed in 94%. Seventy-six percent of assessors reported that the case mix was ,satisfactory' and 20% that it was ,borderline'; 85% of students believed it to have been satisfactory. Generalizability analysis indicates that two independent assessors assessing the performance of students across six consultations would achieve a reliability of 0·94 in making pass or fail decisions. Ninety-eight percent of students perceived that their particular strengths and weaknesses were correctly identified, 99% that they were given specific advice on how to improve their performance and 98% believed that the feedback they had received would have long-term benefit. Conclusions The modified version of the LAP is valid, reliable and feasible in formative assessment of the consultation performance of medical students. Furthermore, almost all students found the process fair and believed it was likely to lead to improvements in their consultation performance. This approach may also be applicable to regulatory assessment as it accurately identifies students at the pass/fail margin.

[source] Near patient testing for glycated haemoglobin in people with Type 2 diabetes mellitus managed in primary care: acceptability and satisfactionDIABETIC MEDICINE, Issue 7 2007M. A. Stone Abstract Aims To assess the acceptability of and satisfaction with near patient testing for glycated haemoglobin in primary care in patients and health professionals. Methods A questionnaire survey and qualitative study were nested within a randomized controlled trial conducted in eight general practices in Leicester-shire, UK. Satisfaction with diabetes care was compared in the intervention group (near patient test) and in the control subjects (usual laboratory test), using the Diabetes Clinic Satisfaction Questionnaire. Semistructured interviews were conducted with a purposive sample of patients and healthcare professionals and analysed using thematic coding and framework charting. Results Questionnaire data for 344 patients were analysed and interviews were conducted with 15 patients and 11 health professionals. Interviews indicated that the near patient test was highly acceptable to patients and staff and confirmed that there may be potential benefits such as time saving, reduced anxiety and impact on patient management and job satisfaction. However, both the survey and the interviews identified high pre-existing levels of satisfaction with diabetes care in both intervention and control group patients and survey results failed to confirm increased patient satisfaction as a result of rapid testing. Limited patient understanding of glycated haemoglobin testing was noted. Conclusions We were unable to confirm actual rather than potential advantages of the near patient test. Widespread adoption in primary care cannot be recommended without further evidence of benefit. [source] Diabetes control and complications: the role of glycated haemoglobin, 25 years onDIABETIC MEDICINE, Issue 7 2004S. L. Jeffcoate Abstract The long-term complications of diabetes have major consequences for individual subjects and growing healthcare delivery and cost implications for society. Evidence for the benefits of good glycaemic control, as monitored by glycated haemoglobin measurements, has been developed in the 25 years since they were introduced to the point where HbA1c assays play central roles in patient management, clinical guidance and audit, and clinical trial design. In this review this evidence is examined and three classes of uncertainty identified that diminish confidence in the effectiveness of these roles for HbA1c. 1Analytical variability between different methods for HbA1c has restricted the application of clinical targets and this problem has recently been addressed by reference method standardization. There are two approaches to this which result in different HbA1c values and this discrepancy needs to be resolved. 2Biological variability in HbA1c values between individuals also restricts its predictive role when applied to populations. The correlations between HbA1c measurements and various components of glycaemia (overall, fasting, postprandial) are still uncertain and differences in protein glycation and de-glycation are greater between subjects than often thought. The influence of variability in erythrocyte life span is an area where research is needed, especially in diabetic subjects. 3Clinical variability is the most important and complex area of uncertainty. A predictive link between HbA1c and clinical outcomes is not as clear-cut as often stated. The correlation with the development of microvascular disease is well established in Type 1 diabetes, but in Type 2 subjects (90% of those with diabetes) the evidence that HbA1c monitoring is of value in predicting or preventing macrovascular disease is not strong, although it is the major cause of morbidity and early death in this group. It is recommended that, as a matter of urgency, these issues be examined, particularly within the context of self-care in diabetes. Diabet. Med. **, ***,*** (2003) [source] Dutch solutions for liquid-based cytology: Analysis of unsatisfactory slides and HPV testing of equivocal cytologyDIAGNOSTIC CYTOPATHOLOGY, Issue 9 2006Mathilde E. Boon M.D., Ph.D. Abstract The liquid-based techniques to obtain microscopy slides for cervical screening have replaced conventional smears almost completely in the USA, but not in all European countries. The decision making process to use liquid-based cytology (LBC) for nationwide screening programs depends on the health system. In a pilot study of over 7,000 screenees, we analyzed the unsatisfactory LBC slides and tested the equivocal cytologies for HPV by using the LiPA test. For comparison over 48,000 conventional screening data were used. Compared to conventional smears, the LBC slides were highly cellular, the state of fixation was much better, and obscuring blood did not exist. The unsatisfactory rate showed an increase from 262/100,000 (conventional smears) to 357/100,000 (LBC slides) due to too thick, undiagnosable epithelial fragments on the LBC slides. HPV testing of the equivocal cytology leads to a better patient management and less unnecessary referrals. Diagn. Cytopathol. 2006;34:644,648. © 2006 Wiley-Liss, Inc. [source] Fine-needle aspiration cytology of salivary glands: Diagnostic pitfalls,revisitedDIAGNOSTIC CYTOPATHOLOGY, Issue 8 2006Arvind Rajwanshi M.D., F.R.C.Path. Abstract Fine needle aspiration cytology (FNAC) of salivary gland lesions is a safe, effective diagnostic technique. Several amply illustrated reviews are available in the English literature. The reported diagnostic accuracy varies between 86% to 98%. The sensitivity ranges from 62% to 97.6% and specificity is higher from 94.3% to 100%. In this present study, we have analyzed 172 cases of salivary gland aspirates and the histopathological diagnosis was available in 45 cases. There was discordance in cytological and histopathological diagnosis in nine cases. Five cases had discrepancies in benign versus malignant diagnosis with four cases being false negative. The errors in these FNA diagnoses were due to sampling error, observational error and interpretational error. Therefore, this study illustrates high diagnostic accuracy of FNAC in salivary gland lesions and shows that FNAC offers valuable information that allows the planning of subsequent patient management.

[source] Urinary bladder biopsy with denuded mucosa: Denuding cystitis,Cytopathologic correlatesDIAGNOSTIC CYTOPATHOLOGY, Issue 5 2004Anil V. Parwani M.D., Ph.D. Abstract Denuding cystitis is often encountered in tissue biopsies of bladder mucosa performed by either cold-cup forceps or wire loop electrocautery to evaluate hematuria or to rule out recurrent urothelial carcinoma. Lack of urothelium in these biopsies is often a frustrating experience, leading to a nonspecific interpretation. In this study, 151 cases of denuding cystitis were retrieved from the surgical pathology files of The Johns Hopkins Hospital over a 4-year period (1996,1999). Patients under the age of 40 years and outside consultation material were excluded. Of the 151 cases of denuding cystitis, 48 patients were identified who had concurrent urinary cytologic studies. Of these patients, 35 were male (73%) and 13 were female (27%). Patient ages ranged from 43 to 85 years (mean, 67). Twenty-six of these 48 patients (54%) had at least one concurrently positive urinary cytology, which was histologically confirmed. All except three cases were high-grade urothelial carcinoma with the following histologic subtypes: flat carcinoma in situ (n = 11), noninvasive papillary (n = 9), and invasive urothelial carcinoma (n = 3). We conclude that urinary cytology is a sensitive modality that detects exfoliated carcinoma cells in patients with a histologic diagnosis of denuding cystitis. An inconclusive diagnosis of denuding cystitis on tissue might be related to biopsy method and technique, small sample size, or biopsy of cystoscopically abnormal urothelium that is denuded. A cytologic diagnosis of high-grade urothelial carcinoma in these cases leads to a timely clinical intervention for optimal patient management. Diagn.

Tytgat SUMMARY., Esophageal cancer and cancer of the gastric cardia, in particular adenocarcinomas, have shown a rapid and largely unexplained increase in incidence in many developed countries around the world. These diseases have a poor prognosis and current therapies have a modest impact on survival. This review presents recent advances in the epidemiology, etiology, diagnosis, staging, prevention and treatment of resectable and advanced disease. Although significant progress has been made in these areas of research and patient management over the past years, prognosis for most patients diagnosed with esophageal cancer or cancer of the gastric cardia remains poor. New diagnostic procedures, improved surgical procedures, combined treatment modalities and new treatment modalities are being evaluated and may be expected to contribute to improved patient outcomes and better palliation of symptoms in the future. [source] ORIGINAL INVESTIGATIONS: Different Clinical Features of Aortic Intramural Hematoma Versus Dissection Involving the Descending Thoracic AortaECHOCARDIOGRAPHY, Issue 8 2005Mariano Falconi M.D. Objective: The objective of this study is to test the hypothesis that the absence of flow communication in aortic intramural hematoma (IMH) involving the descending aorta may have a different clinical course compared with aortic dissection (AD). Methods: We prospectively evaluated clinical and echocardiographic data in AD (76 patients) and IMH (27 patients) of the descending thoracic aorta. Results: Patients did not differ with regard to age, gender, or clinical presentation. IMH and AD had the same predictors of complications at follow-up: aortic diameter (>5 cm) at diagnosis and persistent back pain. Surgical treatment was more frequently selected in AD (39% vs. 22%, P < 0.01) and AD patients who underwent surgical treatment had higher mortality than those with IMH (36% vs. 17%, P < 0.01). There was no difference in mortality with medical treatment (14% in AD vs. 19% in IMH, P = 0.7). During follow-up, of 23 patients with IMH, 11 (47%) showed complete resolution or regression, 6 (26%) increased the diameter of the descending aorta, and typical AD developed in 3 patients (13%). No changes occurred in 14% of the group. Three-year survival rate did not show significant differences between both groups (82 ± 6% in IMH vs. 75 ± 7% in AD, P = 0.37). Conclusion: IMH of the descending thoracic aorta has a relatively frequent rate of complications at follow-up, including dissection and aneurysm formation. Medical treatment with very frequent imaging and timed elective surgery in cases with complications allows a better patient management. [source] A cost-effective simulation curriculum for preclinical endodonticsEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 1 2004Roberta Pileggi A challenge in contemporary dental education is to achieve a smooth transition from preclinical teaching environments to patient-care clinics in a cost-effective manner. The preclinical endodontic courses at The University of Texas, Dental Branch at Houston provide a unique learning environment that enables the student to perform endodontic treatment on extracted teeth in a typodont, and be involved in diagnosis and treatment-planning discussions. The specially designed stone typodont used has built-in radiographic capability, and is mounted at each chair in the clinic. During each preclinical session, students are assigned clinical cubicles and proper aseptic protocol is followed. Students are required to wear gloves, masks and eyewear, and place a rubber dam during treatment. Written self-assessment evaluations based upon prescribed criteria are utilised; feedback is given by faculty composed of both full-time endodontists and graduate students who periodically rotate and are calibrated on a regular basis. In the lecture phase, clinical case scenarios are presented to reinforce concepts of diagnosis and emergency care and to help integrate endodontics with other disciplines; a Socratic-like teaching style is established by the faculty facilitator to create an environment for developing critical-thinking and problem-solving skills. The overall feedback from graduating students has been very positive. Advantages of this format are an easier transition to patient management, a more keen interest in specialsation and a perceived increase in levels of confidence. [source] Immune thrombocytopenic purpura: epidemiology and implications for patientsEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 2009Marc Michel Abstract The age-adjusted prevalence of immune thrombocytopenic purpura (ITP) is estimated to be 9.5 per 100 000 persons in the USA while its annual incidence is estimated to be 2.68 per 100 000 in Northern Europe (at a cut-off platelet count of <100 × 109/L). The mean age of adults at diagnosis in Europe is 50 yrs and the incidence of ITP increases with age. Both the treatments used to treat patients with ITP and the disease itself can impact on patient health-related quality of life (HRQoL). As the incidence of ITP in Europe rises, especially in the elderly, the number of patients with a decreased HRQoL is increasing. Literature searches and focus groups have aided the development of a conceptual model to assess HRQoL. In this model, low platelet counts and the associated symptoms of ITP in addition to the side effects of treatment are proposed as the main determinants of a negatively impacted HRQoL. Primary conceptual domains of HRQoL, affected in patients with ITP, include emotional health, functional health, work, social and leisure activities and reproductive health. As treatment benefits are likely to improve these domains, the conceptual model could be used for better management of patients, taking into account HRQoL. The short-form 36-item questionnaire (SF-36) and the ITP Patient Assessment Questionnaire (ITP-PAQ) are validated measures of HRQoL which can provide a comprehensive assessment of numerous factors to help evaluate decisions about patient management. Future clinical trials investigating treatment options for ITP should assess HRQoL using these validated questionnaires. [source] Do cytogenetic abnormalities precede morphologic abnormalities in a developing malignant condition?EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 2 2007Jill K. Northup Abstract Cytogenetic evaluation of bone marrow and neoplastic tissues plays a critical role in determining patient management and prognosis. Here, we highlight two cases in which the cytogenetic studies challenge the common practice of using hematologic and morphologic changes as key factors in malignant disease management. The first case is that of a lymph node sample from a 40-yr-old non-Hodgkin's lymphoma (NHL) patient sent for determination of disease progress. Hematologic studies showed no evidence of transformation to high-grade NHL (>15% blasts with rare mitotic figures). Cytogenetic studies of lymph node showed multiple clonal abnormalities, most notably a der(18) from a t(14;18) which is associated with high-grade NHL. After two cycles of chemotherapy with fludarabine, the patient did not show any clinical response, suggesting possible progression to high-grade lymphoma. The second case is of a patient with a history of human immunodeficiency virus and blastic natural killer leukemia/lymphoma. Hematologic studies of ascitic fluid classified the patient as having pleural effusion lymphoma whereas bone marrow analysis showed no malignancy. Bone marrow cytogenetic studies showed multiple clonal abnormalities including a t(8;14), which is commonly associated with Burkitt's lymphoma (BL). To our knowledge, this is the first case wherein a morphologically normal bone marrow showed presence of clonal abnormalities consistent with BL or Pleural effusion lymphoma. After two cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy, the patient's general condition and ascitis improved and she was discharged. These studies clearly demonstrate that genetic changes often precede morphologic changes in a developing malignant condition. Therefore, the critical information needed for care of patients with malignant disorders may be incomplete or inaccurate if cytogenetic evaluation is overlooked. [source] Haemophilia care then, now and in the futureHAEMOPHILIA, Issue 2009J. OLDENBURG Summary., Epidemiological data show the benefits of dramatically improved haemophilia care in all life-stages. There are improved administration techniques and dosing regimens, a shift from on-demand treatment to prophylaxis, successful treatment protocols for immune tolerance induction in patients with inhibitors and enhanced approaches to overall patient management. Improvements also include the introduction of virus inactivation methods for plasma derived clotting factor concentrates and the development of recombinant factor VIII therapy, which practically eliminated the risk of infectious disease transmission. Recombinant factor concentrates are recommended as treatment of choice by several guidelines today. All these developments have resulted in increased health-related quality of life and life expectancy in haemophilia patients, who are transitioning from childhood to adulthood with healthy joints and an overall healthy status today. Because of increased life expectancy, these patients are expected to experience age-related clinical problems that were not previously observed in this population. With respect to this, the spectrum of haemophilia care will be extended to diseases of older ages with the need of including further disciplines in comprehensive haemophilia care programmes. Despite these advances, the short half-life of factor VIII, requiring re-administration every 2 or 3 days and the development of inhibitors remains a challenge. Bayer's research and development currently focuses on the optimization of recombinant coagulation factors to address these challenges. Haemophilia care has experienced significant improvements within the past decades. Novel technologies and continued clinical research have facilitated the development of treatment regimen that resulted in dramatic increases in the life expectancy and quality of life of haemophilia patients. To set the scene for the following papers dealing with haemophilia care from paediatrics to geriatrics, developments behind these improvements and some aspects of future research will be presented in this paper. [source] Mucoepidermoid carcinoma of Stensen's duct: A case report and review of the literatureHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 9 2005Roland Giger MD Abstract Background. Mucoepidermoid carcinoma of Stensen's duct is a rare neoplasm, with only five cases reported in the literature. Methods. We report another case of mucoepidermoid carcinoma of Stensen's duct and review the literature. Results. Stensen's duct neoplasms tend to be symptomatic at an early stage by causing an obstruction of the parotid duct. New imaging techniques such as MR sialography and sialoendoscopy are very helpful in diagnosis and patient management. Conclusions. Although the rarity of this condition prevents definitive conclusions about the optimal treatment, we propose that Stensen's duct neoplasms should be treated like similar neoplasms occurring in the parotid gland tissue, taking into consideration clinical stage, tumor grade, and surgical margins. © 2005 Wiley Periodicals, Inc. Head Neck27: XXX,XXX, 2005 [source] The impact of the 2005 International Society of Urological Pathology (ISUP) consensus on Gleason grading in contemporary practiceHISTOPATHOLOGY, Issue 4 2009Piotr Zareba Aims:, To investigate the impact of the 2005 International Society of Urological Pathology (ISUP) Gleason grading consensus in contemporary practice. Methods and results:, The Gleason scores (GS) were compared in two consecutive patient cohorts with matched biopsies and prostatectomies: (i) 908 patients evaluated before the ISUP consensus (July 2000,June 2004) and (ii) 423 patients evaluated after the ISUP consensus (October 2005,June 2007). All biopsies and prostatectomies were performed and scored in one institution and were sampled and processed identically. There was a higher percentage of biopsy and prostatectomy specimens with GS , 7 after the ISUP consensus (GS , 7 on biopsy in 32% before ISUP versus 46% after ISUP; GS , 7 on prostatectomy in 53% before ISUP versus 68% after ISUP; P < 0.001). No significant difference in the complete and ±1 unit Gleason agreement was found before and after the ISUP consensus. There was a trend towards better complete agreement for GS , 7 after the ISUP consensus. Conclusions:, There was a shift towards higher GS on biopsy and prostatectomy in our practice after the ISUP consensus, although , there was no significant impact on the biopsy,prostatectomy Gleason agreement. The significance of this shift for patient management and prognosis is uncertain. [source] A UK-based investigation of inter- and intra-observer reproducibility of Gleason grading of prostatic biopsiesHISTOPATHOLOGY, Issue 6 2006J Melia Aims:, The frequency of prostatic core biopsies to detect cancer has been increasing with more widespread prostate specific antigen (PSA) testing. Gleason score has important implications for patient management but morphological reproducibility data for British practice are limited. Using literature-based criteria nine uropathologists took part in a reproducibility study. Methods:, Each of the nine participants submitted slides from consecutive cases of biopsy-diagnosed cancer assigned to the Gleason score groups 2,4, 5,6, 7 and 8,10 in the original report. A random selection of slides was taken within each group and examined by all pathologists, who were blind to the original score. Over six circulations, new slides were mixed with previously read slides, resulting in a total of 47 of 81 slides being read more than once. Results:, For the first readings of the 81 slides, the agreement with the consensus score was 78% and overall interobserver agreement was , 0.54 for Gleason score groups 2,4, 5,6, 7, 8,10. Kappa values for each category were 0.33, 0.56, 0.44 and 0.68, respectively. For the 47 slides read more than once, intra-observer agreement was 77%, , 0.66. The study identified problems in core biopsy interpretation of Gleason score at levels 2,4 and 7. Patterns illustrated by Gleason as 2 tended to be categorized as 3 because of the variable acinar size and unassessable lesional margin. In slides with consensus Gleason score 7, 13% of readings were scored 6 and in slides with consensus 6, 18% of readings were scored 7. Conclusions:, Recommendations include the need to increase objectivity of the Gleason criteria but limits of descriptive morphology may have to be accepted. [source] HIV and the body: a review of multidisciplinary managementHIV MEDICINE, Issue 2010J Rockstroh Abstract The increase in the life expectancy achieved following the introduction of more effective antiretroviral therapy (ART) in recent years now means that the HIV-infected population are for the first time being exposed to the age-related diseases that affect the general population. Nevertheless, the prevalence of these diseases (which include cardiovascular disease, dyslipidaemia, glucose intolerance and diabetes) is higher, and their onset earlier in the HIV population, probably due to the complex interplay between HIV infection, coinfection with hepatitis B and C, and ART. As a result, HIV physicians are now required to adopt a new approach to the management of HIV, which involves screening and regular monitoring of all HIV-infected individuals for the presence of comorbidities and prompt referral to other clinical specialties when required. If this challenge to patient management is to be overcome, it is clear that educating physicians in the diagnosis and treatment of age-associated comorbidities is essential, either through ongoing programmes such as the HIV and the Body initiative, an overarching independent medical education programme established in 2007 and overseen by an independent Steering Committee, organized and funded by Gilead, and/or through internal training. To assist in this process, this article provides an overview of common comorbidities affecting HIV-infected persons and provides practical guidance on their management. [source] Effects of nucleoside reverse transcriptase inhibitor backbone on the efficacy of first-line boosted highly active antiretroviral therapy based on protease inhibitors: meta-regression analysis of 12 clinical trials in 5168 patientsHIV MEDICINE, Issue 9 2009A Hill Objectives Tenofovir/emtricitabine (TDF/FTC) and abacavir/lamivudine (ABC/3TC) are widely used with ritonavir (RTV)-boosted protease inhibitors (PIs) as first-line highly active antiretroviral therapy (HAART), but there is conflicting evidence on their relative efficacy. The ACTG 5202 and BICOMBO trials suggested higher efficacy for TDF/FTC, whereas the HEAT trial showed no efficacy difference between the nucleoside reverse transcriptase inhibitor (NRTI) backbones. Methods A systematic MEDLINE search identified 21 treatment arms in 12 clinical trials of 5168 antiretroviral-naïve patients, where TDF/FTC (n=3399) or ABC/3TC (n=1769) was used with RTV-boosted PI. For each NRTI backbone and RTV-boosted PI, the percentage of patients with viral load <50 HIV-1 RNA copies/mL at week 48 by standardized Intent to Treat, Time to Loss of Virological Failure (ITT TLOVR) analysis were combined using inverse-variance weighting. The effect of baseline HIV RNA, CD4 cell count and choice of NRTI backbone were examined using a weighted analysis of covariance. Results Across all the trials, HIV RNA suppression rates were significantly higher for those with baseline viral load below 100 000 copies/mL (77.2%) vs. above 100 000 copies/mL (70.9%) (P=0.0005). For the trials of lopinavir/ritonavir (LPV/r), atazanavir/ritonavir (ATV/r) and fosamprenavir/ritonavir (FAPV/r) using either TDF/FTC or ABC/3TC, the HIV RNA responses were significantly lower when ABC/3TC was used, relative to TDF/FTC, for all patients (P=0.0015) and for patients with baseline viral load <100 000 copies/mL (70.1%vs. 80.6%, P=0.0161), and was borderline for those with viral load >100 000 copies/mL (67.5%vs. 71.5%, P=0.0523). Conclusions This systematic meta-regression analysis suggests higher efficacy for first-line use of a TDF/FTC NRTI backbone with boosted PIs, relative to use of ABC/3TC. However, this effect may be confounded by differences between the trials in terms of baseline characteristics, patient management or adherence. [source] Myocardial perfusion imaging in evaluation of undiagnosed acute chest painINTERNAL MEDICINE JOURNAL, Issue 9 2001J. C. Knott Abstract Myocardial perfusion imaging is a relatively new technique in the emergency department management of acute chest pain. With improved sensitivity and specificity compared to traditional methods of risk stratification, an abnormal scan rapidly identifies individuals with acute perfusion abnormalities and allows the appropriate utilization of limited resources. Conversely, a normal scan allows prompt hospital discharge and is associated with excellent outcomes both in the short and medium terms. Acute chest pain myocardial perfusion imaging has been demonstrated to alter patient management and disposition and its routine use results in decreased costs in the intermediate risk population.

BASORA Summary A poor preoperative haemoglobin (Hb) status is frequently encountered among adult patients scheduled for corrective surgery of the locomotive system, representing the main risk factor for blood transfusion. The soluble transferrin receptor (sTfR) has become a highly specific parameter for the detection of iron deficits as it can differentiate between iron deficiency anaemia and anaemia of chronic disease, because of the lack of effect by associated inflammation, unlike ferritin. The objectives of this study were to evaluate patients with the prevalence of risk for transfusion, the effect of inflammation on ferritin (F) values and functional iron deficiency in elderly patients with advanced degenerative arthropathy scheduled for hip or knee replacement. This observational, prospective study included patients over 50 years, operated for hip or knee replacements between April and June 2004. Of 218 patients studied, 87 (39%) presented with Hb levels between 10 and 13 g/dl. The prevalence of functional iron deficit was 27% (sTfR > 1.76 mg/l), while only 8.6% of patients displayed F levels below normal. As expected, C-reactive protein levels were elevated in 24.8% of patients and erythrocyte sedimentation rate was elevated in 50%. These inflammatory markers did not correlate with levels of either F or sTfR. Multiple factors can affect F levels, such as the inflammatory status of osteoarthritis in the elderly, obesity, nonsteroidal anti-inflammatory drugs therapy and low physical performance. As sTfR is not affected by inflammation, it has emerged as a primary parameter for the evaluation of iron status during preoperative assessment among patients scheduled for arthroplasty surgery. Our data strongly suggest that sTfR measurement contributes to improve patient management. [source] A study to assess the validity of clinical judgement in determining paediatric dental anxiety and related outcomes of managementINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2005R. D. HOLMES Summary. Objective. The aim of the present study was to determine the validity of subjective anxiety assessment and the outcomes of management of children receiving operative dental treatment. Setting., The study was conducted at the Departments of Sedation and Child Dental Health, Newcastle Dental Hospital, Newcastle upon Tyne, UK. Subjects and methods., One hundred children and adolescents aged between 8 and 15 years participated in the study. Clinicians subjectively allocated 50 children for treatment with local analgesia alone (low anxiety), and identified 50 children who had the potential to benefit from nitrous oxide and oxygen sedation (high anxiety). Participants then completed the State-Trait Anxiety Inventory for Children (STAIC), the Venham Picture Test (VPT) and the Child Fear Survey Schedule , Dental Subscale (CFSS-DS). A global rating scale classified behaviour during dental treatment. Results., State anxiety and dental fear prior to treatment were significantly higher in children allocated to receive inhalation sedation (P = 0·004 and P = 0·005, respectively). There was no significant difference in trait anxiety or post-treatment state anxiety between the two groups (P = 0·69 and P = 0·06, respectively). Only 11% displayed ,negative' behaviour during treatment: 82% of this group represented those allocated to receive sedation. Conclusion., Children receiving inhalation sedation were significantly more anxious prior to treatment than children receiving treatment with local analgesia alone. The findings support the subjective assessment of anxiety in children; however, objective anxiety measures may assist clinicians in identifying specific fears, which may ultimately aid patient management.

Ram Summary .,Fear-related behaviours have long been recognized as the most difficult aspect of patient management and can be a barrier to good care. Anxiety is one of the major issues in the dental treatment of children, and the injection is the most anxiety-provoking procedure for both children and adults. There is a constant search for ways to avoid the invasive, and often painful, nature of the injection, and to find more comfortable and pleasant means for anaesthesia before dental procedures. Objective. The purpose of the present review is to summarize relevant data on topics connected with the administration of local anaesthesia. Methods. The review will survey the current available methods, viz. electronic anaesthesia, lidocaine patch, computerized anaesthesia (the Wand), and the syrijet as well as the conventional injection, used for paediatric patients. Conclusions. Usually new techniques for locally anaesthetizing dental patients are tested on adults. However, despite recent research in the field, the injection remains the method of choice. It is necessary to continue to conduct studies using new techniques on adults and children, so that a more acceptable technique can be found. [source] Corticosteroid Osteoporosis: Practical Implications of Recent TrialsJOURNAL OF BONE AND MINERAL RESEARCH, Issue 9 2000Philip N. Sambrook Abstract Corticosteroids are widely used and effective agents for control of many inflammatory diseases, but osteoporosis is a common problem associated with their long-term use. Several large double-blind controlled clinical trials in patients with corticosteroid osteoporosis recently have been published, indicating it is possible to prevent or reverse this bone loss. Ultimately, the aim of treatment is to prevent fractures, especially vertebral fractures that are the most common type of fracture associated with corticosteroid therapy, yet it remains unclear exactly which patients should receive prophylaxis. Understanding the differences between these trials is key to interpreting the results, which have important practical implications for patient management. [source] Views of xerostomia among health care professionals: a qualitative studyJOURNAL OF CLINICAL NURSING, Issue 6 2009Solgun Folke Aim., To explore and describe views of xerostomia among health care professionals. Background., Xerostomia (dry mouth) is caused by changes in quality and quantity of saliva due to poor health, certain drugs and radiation therapy. It is a common symptom, particularly among older people and has devastating consequences with regard to oral health and general well-being. Methods., Data were obtained and categorised by interviewing 16 health care professionals. Qualitative content analysis was chosen as the method of analysis. Design., Qualitative. Results., The latent content was formulated into a theme: xerostomia is a well-known problem, yet there is inadequate management of patients with xerostomia. The findings identified three categories expressing the manifest content: awareness of xerostomia, indifferent attitude and insufficient support. Conclusions., Although xerostomia was recognised as commonly occurring, it was considered to be an underestimated and an ignored problem. Proper attention to conditions of xerostomia and subsequent patient management were viewed as fragmentary and inadequate. Additional qualitative studies among patients with xerostomia would be desirable to gain further understanding of the problems with xerostomia, its professional recognition and management. Relevance to clinical practice., A holistic view, positive professional attitudes and enhanced knowledge of xerostomia seem essential to augment collaboration among health care professionals and to improve compassion for and support of patients with xerostomia. [source] A case report of inflammatory nonscarring alopecia associated with the epidermal growth factor receptor inhibitor erlotinibJOURNAL OF CUTANEOUS PATHOLOGY, Issue 12 2009Marinya Pongpudpunth Epidermal growth factor receptor inhibitors (EGFRIs) are new anticancer agents that act by inhibiting EGFR signaling transduction pathways, thus decreasing tumor growth. In more than 30 countries, EGFRIs are currently used in the treatment of a number of solid tumors, and other indications are being sought. In the United States, select EGFRIs have been approved in certain patients with non-small cell lung cancer, metastatic colorectal carcinoma, and advanced squamous cell carcinoma of the head and neck. Various cutaneous side effects of EGFRIs have been reported, including acneiform eruptions, chronic paronychia, xerosis, a seborrheic dermatitis-like eruption, changes in hair texture, and nonscarring alopecia. We present a 60-year-old woman with non-small cell lung cancer who developed a persistent generalized itchy eruption and progressive nonscarring alopecia shortly after initiation of erlotinib (Tarceva). Scalp biopsy showed near-equal number of anagen and catagen/telogen hair follicles, and a superficial and deep perivascular lymphoplasmocytic infiltration. These changes are typical of the nonscarring alopecia induced by EGFRIs. Because it is likely that EGFRIs will be increasingly used, dermatopathologists are likely to see more reactions from these agents. Familiarity with their side effects is essential to accurate diagnosis and effective patient management. [source] Discordance in the histopathologic diagnosis of difficult melanocytic neoplasms in the clinical settingJOURNAL OF CUTANEOUS PATHOLOGY, Issue 4 2008Saurabh Lodha Background:, The gold standard for diagnosing melanocytic neoplasms is by histopathologic examination. However, lack of agreement among expert dermatopathologists in evaluating these tumors has been well established in experimental settings. Objective:, This study examines the discordance among dermatopathologists in evaluating difficult melanocytic neoplasms in a clinical setting where the diagnosis impacts patient management. Methods:, Retrospective review of consultation reports over a 6-year period. Results:, There was complete agreement among the consultants in 54.5% of the cases. However, a high level of disagreement was found in 25% of the cases. Limitations:, The analysis was limited to two consultant dermatopathologists. Conclusions:, There are limitations to the practical applications of histologic criteria for diagnosing difficult melanocytic tumors. It is not malpractice for a pathologist to have rendered a diagnosis that did not predict clinical outcome as long as ,standard of care' has been followed in his/her evaluation of the specimen. [source] Ductal eccrine carcinoma with squamous differentiation: apropos a caseJOURNAL OF CUTANEOUS PATHOLOGY, Issue 6 2007Vishesh Chhibber Sweat gland carcinomas are rare. Given this, they can pose a diagnostic challenge especially in shave biopsy specimens. We present a case of ductal eccrine carcinoma with extensive squamoid differentiation that was repeatedly misdiagnosed by multiple dermatopathologists as squamous cell carcinoma in the initial few biopsies. As the distinction between these two neoplasms is crucial to patient management, we highlight the histologic features of this uncommon entity to highlight the potential diagnostic pitfalls.
