Kinds of Medicine Physicians Selected AbstractsFinancing the Treatment of Chronic Pain: Models for Risk-sharing among Pain Medicine Physicians, Health Care Payers, and ConsumersPAIN MEDICINE, Issue 1 2000FABPM, Richard L. Stieg MD Chronic pain patients are among a growing group of medically underserved Americans. Despite increasing public awareness about pain and widespread legislative activity that is focusing on the needs of pain patients, there remain significant roadblocks in bringing the expertise of Pain Medicine specialists to these unfortunate people. This paper explores how the managed care revolution has impacted the practice of Pain Medicine in the United States. The dissolution of many prominent multi-disciplinary pain treatment centers has been paralleled by the evolution of pain management as an area of interest by several competing medical specialty societies. Despite this fragmentation, the American Academy of Pain Medicine continues to grow and to promote the needs of Pain Medicine specialists and their patients. The advantages and disadvantages of various practice patterns for Pain Medicine specialists is explored against a backdrop of discussions about: (1) the problems currently faced by chronic pain patients; (2) the role of organized Pain Medicine in helping patients to access and finance care; and (3) the future of American health care and the new responsibilities that will bring to physicians. Finally, we have some specific recommendations for pain medicine specialists about: (1) sharing risk; (2) exerting individual leadership; and (3) simplifying one's professional life in the new health care environment, that we hope will enable them to continue caring for as many chronic pain patients as possible. It is opined that the development of sophisticated regional specialty networks is the best model to accomplish this task in the future.

Khalid MD Abstract Background. Technetium 99m sestamibi scans have become a principal means of localizing parathyroid adenomas. Its accuracy and reliability has allowed for the proliferation of minimal access parathyroidectomy. Localizing interpretation of these scans often drives referral of hyperparathyroid patients for surgery. Interpretation of these scans may differ between nuclear medicine physicians and surgeons. Methods. We reviewed patients (N = 65) with digital images from an academic medical center with the diagnosis of primary hyperparathyroidism. We assessed the willingness to define an adenoma's location, the interrater reliability, and the accuracy of technetium (Tc-99m) sestamibi read by a surgeon and a nuclear medicine physician. Results. There was poor correlation between both readers for assessment of quality of images (k = 0.54, 0.07) but very good correlation for adenoma location (k = 0.81). Conclusion. Both readers had good accuracy in predicting the location of the parathyroid adenoma. The surgeon was more likely to call a scan positive. © 2008 Wiley Periodicals, Inc. Head Neck, 2009 [source] The Impact of Herbal Medicines on Dermatologic SurgeryDERMATOLOGIC SURGERY, Issue 8 2001Lawrence K. Chang MD Background. In recent years herbal medicines and supplements have become increasingly popular. With their increased popularity, more publications are warning about the potential harmful effects of some of these products. Objective. To present scientific evidence of the benefits and surgical risks of herbal products. Methods. A Medline search and review of the literature was performed. Results. Many herbal medicines are relevant in dermatologic surgery since Ginkgo biloba, garlic, ginger, ginseng, feverfew, and vitamin E may increase the risk of bleeding, and ephedra may potentiate the side effects of epinephrine. Conclusion. Dermatologists should be aware of these herbal products and their uses. Many of these products prescribed by alternative medicine physicians or purchased over the counter should be discontinued prior to dermatologic surgery to minimize the risk of surgical complications.

Head Neck, 2009 [source] Lessons from a review of thyroglobulin assays in the management of thyroid cancerINTERNAL MEDICINE JOURNAL, Issue 6a 2008J. Wong Abstract Thyroglobulin (Tg) measurement has become increasingly an important and integral part of the follow up and management of patients with differentiated thyroid cancer. Clinicians predominantly rely on Tg for decision-making for surveillance of patients with differentiated thyroid cancer, but despite this new reliance, issues regarding Tg measurement have not been appropriately addressed especially within a local context. In the process of developing an institutional protocol we have identified that there are significant clinical and technical issues regarding Tg measurement, and surprisingly Tg assessment is currently not part of an external quality control programme. We conducted a small pilot study to specifically emphasize some of the assay issues. We aim to inform endocrinologists, pathologists and nuclear medicine physicians, the need and urgency for these issues to be addressed to improve the ongoing surveillance of differentiated thyroid cancer. [source] Sentinel lymph node biopsy in patients with melanoma and breast cancerINTERNAL MEDICINE JOURNAL, Issue 9 2001R. F. Uren Abstract Sentinel lymph node biopsy (SNLB) is a new method for staging regional node fields in patients with cancers that have a propensity to metastasise to lymph nodes. The majority of early experience has been obtained in patients with melanoma and breast cancer. The technique requires the close cooperation of nuclear medicine physicians, surgical oncologists and histopathologists to achieve the desired accuracy. It involves: (i) identification of all lymph nodes that directly drain a primary tumour site (the sentinel nodes) by the use of pre-operative lymphoscintigraphy, (ii) selective excision of these nodes by the surgeon, guided by pre-operative blue dye injection and a gamma detecting probe intra-operatively and (iii) careful histological examination of the sentinel nodes by the histopathologist using serial sections and immunohistochemical stains. If the nodes are normal it can be inferred with a high degree of accuracy that all nodes in the node field are normal. This means that radical dissections of draining node fields can be avoided in patients with normal lymph nodes. A further advantage of lyamphatic mapping is that drainage to sentinel nodes in unusual locations is identified, leading to more accurate nodal staging than could be achieved with routine dissection of the closest node field.

Hayashi MD Physician house calls are an important but underused mode of delivering health care to a growing population of homebound elderly patients. One major barrier to internal medicine physicians making house calls is a lack of training in this setting. This article describes a needs assessment survey of residents from nine internal medicine residency programs for a house call curriculum that combines a longitudinal clinical experience with Internet-based learning. Implementation of the curriculum was begun in July 2006, and data will be collected and results evaluated for at least 2 years. Several educational outcomes from the intervention are anticipated, including increased learner knowledge of house call medicine, improved learner confidence in making house calls, and program director satisfaction with the curriculum. This early work lays the foundation for determining the effect of a carefully designed curriculum on the number of practicing internists with the skills, knowledge, and attitudes necessary to meet the growing need for physician house calls. [source] Are Internal Medicine Residency Programs Adequately Preparing Physicians to Care for the Baby Boomers?JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2006A National Survey from the Association of Directors of Geriatric Academic Programs Status of Geriatrics Workforce Study Patients aged 65 and older account for 39% of ambulatory visits to internal medicine physicians. This article describes the progress made in training internal medicine residents to care for older Americans. Program directors in internal medicine residency programs accredited by the Accreditation Council for Graduate Medical Education were surveyed in the spring of 2005. Findings from this survey were compared with those from a similar 2002 survey to determine whether any changes had occurred. A 60% response rate was achieved (n=235). In these 3-year residency training programs, 20 programs (9%) required less than 2 weeks of clinical instruction that was specifically structured to teach geriatric care principles, 48 (21%) at least 2 weeks but less than 4 weeks, 144 (62%) at least 4 weeks but less than 6 weeks, and 21 (9%) required 6 or more weeks. As in 2002, internal medicine residency programs continue to depend on nursing home facilities, geriatric preceptors in nongeriatric clinical ambulatory settings, and outpatient geriatric assessment centers for their geriatrics training. Training was most often offered in a block format. The mean number of physician faculty per residency program dedicated to teaching geriatric medicine was 3.5 full-time equivalents (FTEs) (range 0,50), compared with a mean of 2.2 FTE faculty in 2002 (P,.001). Internal medicine educators are continuing to improve the training of residents so that, as they become practicing physicians, they will have the knowledge and skills in geriatric medicine to care for older adults. [source] Patient and physician predictors of inappropriate acid-suppressive therapy (AST) use in hospitalized patients,JOURNAL OF HOSPITAL MEDICINE, Issue 8 2009Jagdish S. Nachnani MD Abstract BACKGROUND: The use of acid suppressive therapy (AST) in prevention of stress ulcers has been well defined in critical care patients, though its use has become increasingly common in general medicine patients, with little to no supportive evidence. None of the previous studies has examined the patient and physician characteristics of inappropriate AST initiation and use in hospitalized patients. The aim of our study was to identify: (1) the appropriateness of AST in hospitalized patients and the cost associated with inappropriate use; and (2) patient and physician characteristics predicting inappropriate initiation and use of AST. METHODS: All discharges over a period of 8 consecutive days were selected. RESULTS: There were 207 patients discharged over a period of 8 days. AST was inappropriately initiated in 92 of 133 (69.2%) patients included in our study. On univariate analysis, higher hemoglobin value, postgraduate year 1 (PGY-1) residents, physicians with an MD degree, international medical graduates (IMGs), and internal medicine physicians were more likely to prescribe AST inappropriately. On multivariate analysis, a higher hemoglobin value, PGY-1 residents, and MD physicians were factors associated with inappropriate AST use. The total direct patient cost for this inappropriate use was $8026, with an estimated annual cost of approximately $366,000. CONCLUSIONS: AST was inappropriately initiated in 69.2% of patients with increased direct costs of $8026. Residents in their first year of training as well physicians with a MD degree are more likely to initiate AST inappropriately. Curtailing the inappropriate use of AST therapy may reduce overall costs for the patient and institution. Journal of Hospital Medicine 2009;4:E10,E14. © 2009 Society of Hospital Medicine. [source] Problems and Risks of Unsolicited E-mails in Patient-Physician Encounters in Travel Medicine SettingsJOURNAL OF TRAVEL MEDICINE, Issue 3 2001Andreas Sing Background: International travel and use of modern information technology are expressions of modern life style. Seeking on-line travel health advice via E-mail for preventive (teleprevention) or diagnostic reasons may become increasingly popular among patients with financial resources and Internet access. This study was undertaken to compare the behavior of travel clinic or tropical medicine physicians and other providers of travel-related medical information services toward unsolicited E-mails from fictitious patients in pretravel and post-travel scenarios. We also wanted to test the potential of E-mail advice for preventive medicine (teleprevention), and to find out how the "Good Samaritan Law" is observed. Methods: Two different E-mails were posted to E-mail addresses of 171 physicians (members of travel health and/or tropical medicine societies) and services offering advice on travel health issues identified by an AltaVista search. These E-mails, from two different fictitious travelers, were asking for advice regarding malaria prophylaxis in a pretravel scenario and describing symptoms suggesting acute malaria. Results: Of the contacted addresses 43.3% and 49.7% respectively, replied to the pre- and post-travel E-mail. Of those suggesting antimalarial chemoprophylaxis in the pretravel scenario, 13.2% proposed inadequate regimens, and at least 3.5% of the post-travel replies were inappropriate. The "Good Samaritan Law" was observed by a significant number of physicians. Conclusions: Both patients and physicians have to be aware of the limitations of E-mail communication. Guidelines protecting physicians against legal and ethical consequences of this new communication technology are urgently needed. [source] Parkinson's disease mortality among male anesthesiologists and internistsMOVEMENT DISORDERS, Issue 12 2005Chava Peretz PhD Abstract Clusters of Parkinson's disease (PD) among healthcare professionals have been interpreted as evidence of an infectious etiology. Anesthetic gases have also been associated with parkinsonism symptoms and PD among patients undergoing general anesthesia. We investigated PD mortality among large cohorts of male U.S. anesthesiologists (n = 33,040) and internal medicine physicians (n = 33,044). PD mortality for any mention on a death certificate was lower than rates in U.S. men during 1979,1995 for both groups, although anesthesiologists had a significantly elevated risk for PD as underlying cause of death for 10-year follow-up. Direct comparisons of mortality between the two cohorts indicated excess PD mortality in anesthesiologists for >10-year follow-up for any mention and for underlying cause of death. These findings lend some support to the hypothesis that infectious agents or anesthetic gases may be associated etiologically with PD. © 2005 Movement Disorder Society [source] Emergency Medicine Resident Attitudes and Perceptions of HIV Testing Before and After a Focused Training Program and Testing ImplementationACADEMIC EMERGENCY MEDICINE, Issue 11 2009Yu-Hsiang Hsieh MSc Abstract Objectives:, The objectives were to determine attitudes and perceptions (A&P) of emergency medicine (EM) residents toward emergency department (ED) routine provider-driven rapid HIV testing services and the impact of both a focused training program (FTP) and implementation of HIV testing on A&P. Methods:, A three-phase, consecutive, anonymous, identity-unlinked survey was conducted pre-FTP, post-FTP, and 6 months postimplementation. The survey was designed to assess residents' A&P using a five-point Likert scale. A preimplementation FTP provided both the rationale for the HIV testing program and the planned operational details of the intervention. The HIV testing program used only indigenous ED staff to deliver HIV testing as part of standard-of-care in an academic ED. The impact of the FTP and implementation on A&P were analyzed by multivariate regression analysis using generalized estimating equations to control for repeated measurements in the same individuals. A "favorable" A&P was operationally defined as a mean score of >3.5, "neutral" as mean score of 2.5 to 3.5, and "unfavorable" as mean score of <2.5. Results:, Thirty of 36 residents (83.3%) participated in all three phases. Areas of favorable A&P found in phase I and sustained through phases II and III included "ED serving as a testing venue" (score range = 3.7,4.1) and "emergency medicine physicians offering the test" (score range = 3.9,4.1). Areas of unfavorable and neutral A&P identified in phase I were all operational barriers and included required paperwork (score = 3.2), inadequate staff support (score = 2.2), counseling and referral requirements (score range = 2.2,3.1), and time requirements (score = 2.9). Following the FTP, significant increases in favorable A&P were observed with regard to impact of the intervention on modification of patient risk behaviors, decrease in rates of HIV transmission, availability of support staff, and self-confidence in counseling and referral (p < 0.05). At 6 months postimplementation, all A&P except for time requirements and lack of support staff scored favorably or neutral. During the study period, 388 patients were consented for and received HIV testing; six (1.5%) were newly confirmed HIV positive. Conclusions:, Emergency medicine residents conceptually supported HIV testing services. Most A&P were favorably influenced by both the FTP and the implementation. All areas of negative A&P involved operational requirements, which may have influenced the low overall uptake of HIV testing during the study period. [source] Development of a parathyroid database in Melbourne and review of the last 50 casesANZ JOURNAL OF SURGERY, Issue 9 2004Meei J. Yeung Background: Minimally invasive parathyroidectomy (MIP) is only possible if preoperative localization studies accurately identify the abnormal parathyroid tissue. The aim of the present paper was to evaluate the accuracy of these studies in our geographical region and the consequences on MIP. Methods: A Filemaker Pro database was designed and a retrospective analysis was carried out on the last 50 parathyroidectomies. Results: There were a total of 49 patients who underwent parathyroidectomy; with one patient having two operations. Forty-nine preoperative ultrasound localization studies were performed. Ultrasound sensitivity of correct localization of abnormal parathyroids was 41% with a false positive rate of 25%. Twenty-two sestamibi scans identified 14 abnormal parathyroids. Sestamibi scanning had a sensitivity of 32% for correct localization and a false positive rate of 32%. There were 16 different radiologists or nuclear medicine physicians involved with the nuclear medicine scans, and 22 different radiologists involved in the preoperative ultrasound scans. Forty-seven patients were cured of hyperparathyroidism after a primary operation, with a total of 48 patients in all being cured following re-exploration. One patient was lost to follow up. The success of primary exploration was therefore 96% and following re-exploration this increased to 98%. Conclusion: We found preoperative localization studies to have low sensitivities and high false positive rates. To move successfully towards MIP, we need to identify a radiologist with a special interest in localization studies to achieve greater accuracy. [source] Is 18F-fluorodeoxyglucose positron emission tomography scanning a reliable way to assess disease activity in takayasu arteritis?ARTHRITIS & RHEUMATISM, Issue 4 2009Laurent Arnaud Objective 18F-fluorodeoxyglucose,positron emission tomography (FDG-PET) scanning has been proposed as a new way of assessing disease activity in Takayasu arteritis (TA), but previous studies have used the nonvalidated National Institutes of Health (NIH) global activity criteria, and thus might be biased. This study was undertaken to determine the value of PET scanning for assessment of disease activity in TA, by comparing PET scan data with clinical, biologic, and magnetic resonance imaging (MRI) data assessed separately. Methods Twenty-eight patients with TA (according to the American College of Rheumatology criteria) underwent a total of 40 PET scans. Images were reviewed by 2 pairs of independent nuclear medicine physicians and assessed for pattern and intensity of vascular uptake. TA activity data were obtained within 15 days of the PET scans. Results PET scanning revealed abnormal vascular uptake in 47% of the 40 examinations. The uptake intensity grade was 0 in 7 scans, grade 1 in 7 scans, grade 2 in 13 scans, and grade 3 in 13 scans. Morphologic analysis was conducted by grading the pattern of the vascular uptake as diffuse (73%), segmental (20%), or focal (13%). There was a trend toward an association between clinically active disease and the semiquantitative assessment of FDG uptake (P = 0.08). We found no statistical association between levels of acute-phase reactants and intensity of uptake. There was no significant association between the semiquantitative assessment of FDG uptake and the presence of vascular wall thickening (P = 0.23), gadolinium uptake (P = 0.73), or the presence of vascular wall edema (P = 0.56). Conclusion Our findings indicate that there is no association between FDG vascular uptake intensity and clinical, biologic, or MRI assessment of disease activity. Previous studies using the nonvalidated NIH global activity criteria are likely biased. [source] Model for Ultrasound-Assisted Lumbar Puncture TrainingACADEMIC EMERGENCY MEDICINE, Issue 2009Melissa Bollinger Lumbar puncture is an important diagnostic procedure in emergency medicine. Data have been published showing improved success rate with ultrasound assistance and the ability of emergency medicine physicians to recognize sonographic lumbar spinous anatomy. However, with educational models and the push for improved patient safety, procedural skills should be practiced on phantoms rather than the "see one, do one, teach one" of the past. There are no currently available phantoms for ultrasound-assisted lumbar puncture training. We have produced a phantom that can be used to train physicians on ultrasound-assisted lumbar puncture with respect to both imaging and procedural competency. A plastic fluid-filled bladder was immersed in gelled opacified mineral oil, a safe and easily used tissue mimic that obscures direct visualization of structures. Spinous anatomy is replicated with the use of wooden struts supporting wooden disks that mimic lumbar spinous processes. The spine analog was mounted over the plastic bladder and surrounded with gelled mineral oil. The phantom produces images similar to human lumbar anatomy. The phantom allows insertion of spinal needles into the "interspinous spaces" with inability to pass the needle outside of those locations. Fluid collection and repeated punctures can be performed on the phantom. Appearance and performance of the phantom were evaluated by physicians with expertise in ultrasound-assisted lumbar puncture. The only limitation is that external appearance is not realistic. This model performs well, is made from readily available materials, and can be used to train physicians in ultrasound-assisted lumbar puncture. [source] Caring for cancer survivors,CANCER, Issue S18 2009A survey of primary care physicians Abstract BACKGROUND: The number of long-term US cancer survivors is expected to double by the year 2050. Although primary care physicians (PCPs) provide the majority of care for long-term cancer survivors, to the authors' knowledge, few data to date have detailed PCP practice patterns, attitudes, and challenges in caring for long-term cancer survivors. METHODS: Self-administered surveys were mailed to 406 community- and academic-based general internal medicine physicians in Denver, Colorado. Survey development included in-depth physician interviews and pretesting. Of the 299 responses, 72 were ineligible; an analysis of the data from 227 surveys is presented. RESULTS: The response rate was 76%. Community-based PCPs comprised 70% of completed surveys. Reported care patterns were assessed to create a multidimensional care score reflecting levels of attention to 4 areas of survivorship care: monitoring for cancer recurrence, management of late effects, sexual functioning, and mental health. Only 24% of PCPs met criteria for routinely providing more multidimensional survivorship care. More recent medical school graduates reported providing less multidimensional survivorship care when compared with their more experienced colleagues. Approximately 82% of PCPs believed that primary care guidelines for adult cancer survivors are not well defined, and 47% of PCPs cited inadequate preparation and lack of formal training in cancer survivorship as a problem when delivering care to long-term survivors. CONCLUSIONS: Although PCPs provide the bulk of care for long-term survivors within the survivorship phase of the cancer trajectory, only a small subset have reported providing multidimensional survivorship care. Results underscore a need for substantially increased training in survivorship care to support the delivery of multidimensional primary care for long-term survivors.

[source] Variability of the administered radioiodine doses for the treatment of hyperthyroidism in BelgiumCLINICAL ENDOCRINOLOGY, Issue 2 2006Marianne Tondeur Summary Objective,, When using radioiodine for hyperthyroidism there is no consensus regarding the administration of fixed or calculated doses. Guidelines do not specify the preferable approach or the parameters to use to calculate the dose. Therefore, the dose might be quite different with regard to the chosen procedure. This study was undertaken to evaluate the variability of the amount of radioiodine administered in Belgium in various cases of hyperthyroidism. Design and patients, Twenty-one Belgian nuclear medicine physicians received summarized clinical files from 10 patients suffering from overt hyperthyroidism (n = 7) or subclinical hyperthyroidism (n = 3). Five patients had homogeneous goiters, one had multinodular goiter, and four had hot nodule. Participants had to determine the radioiodine dose (millicuries, mCi) they would give in each case. Results,, Proposed doses varied between 2 mCi and 25 mCi. Mean proposed dose for nodular disease was 10·71 mCi; it was 6·79 mCi for homogeneous goiter. For individual cases, a difference between the lowest and the highest dose of more than 17 mCi was observed in more than 50% of the cases. Conclusions,, We believe that more precise guidelines are mandatory, underlying uncertainties, controversies but recommending however, as minimal and maximal doses to administer, as well as clinical and biological parameters, if any, to be taken into account in order to modulate these doses.
