1/28. Beyond the biopsychosocial model: new approaches to doctor-patient interactions.BACKGROUND: The biopsychosocial model has been a cornerstone for the training of family physicians; however, little is known about the use of this model in community practice. This study, conducted in an urban Native American health center, examined the application of the biopsychosocial model by an experienced family physician (Dr M). methods: Interactions between Dr M and 9 Native Americans with type 2 diabetes were audio-recorded following preliminary interviews. Interpretations of the interactions were elicited from Dr M through interpersonal process recall and interpretive dialogue sessions. The author analyzed this data using techniques from interpretive anthropology and narrative discourse analysis. RESULTS: In a preliminary interview, Dr M described a sophisticated biopsychosocial approach to practice. However, she viewed her actual interactions with these patients as imbued with misunderstanding, mistrust, and disconnection. This occurred in spite of her experience and commitment to providing culturally sensitive primary care. CONCLUSIONS: Biopsychosocial models of disease may conflict with patient-centered approaches to communication. To overcome difficulties in her practice environment, Dr M adopted a strategy that combined an instrumental biopsychosocial approach with a utilitarian mode of knowing and interacting with patients. The misunderstandings, mistrust, and constrained interactions point to deeper problems with the way knowledge is formed in clinical practice. We need further understanding of the interrelationships between physicians' clinical environments, knowledge of patients, and theories of disease. These elements are interwoven in the physicians' patient-specific narratives that influence their interactions in primary care settings.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/28. Diabetes management. Analysis of the American Diabetes association's clinical practice recommendations.Type 2 diabetes generally develops in persons older than age 45 and comprises more than 90% of the estimated 15 million diabetes cases identified in the united states. Due to the burgeoning population of older Americans and the increased prevalence of obesity and sedentariness, type 2 diabetes is nearing epidemic proportions. Tight glycemic control combined with good diet and regular exercise can reduce the incidence of complications associated with unchecked disease. To help physicians and patients achieve such objectives, the American Diabetes association publishes clinical practice recommendations that propose the most effective methods for screening, diagnosis, and disease management. The position statements presenting the standard of care for treatment of diabetes are reviewed and critiqued from an evidence-based medicine perspective.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
3/28. Bell's palsy during interferon therapy for chronic hepatitis c infection in patients with haemorrhagic disorders.Two adult patients with life-long severe haemorrhagic disorders commenced on interferon-alpha2b therapy for chronic hepatitis c infection. Both developed Bell's palsy several weeks after commencing therapy, They were started on steroids and, in addition, the first patient discontinued interferon-alpha2b therapy while the second patient elected to continue with therapy. In both cases facial paralysis improved over the ensuing weeks. Bell's palsy is often idiopathic but has been reported. in association with herpesviruses. It is not a recognised complication of chronic hepatitis b or C infection, or interferon-alpha2b therapy. However, the interferons are associated with numerous adverse reactions including various neuropsychiatric manifestations and neurological syndromes. There are several reports of nerve palsies, including optic tract neuropathy, occurring during interferon therapy, and immune-based mechanisms are thought to play a role in the aetiopathogenesis. No reports of Bell's palsy in association with interferon therapy were identified in our literature search, although one possible case has been reported to the Committee of safety in Medicine. Although Bell's palsy in our patients may have occurred by chance, a neuropathic effect of interferon-alpha2b on the facial nerve cannot be excluded and we urge physicians using interferons to be aware of this potential side-effect.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
4/28. Three patients with adrenal tumors having been treated simply for diabetes mellitus.Three patients with functional adrenal tumors, Cushing's syndrome, primary aldosteronism and pheochromocytoma, who underwent adrenalectomy and were subsequently cured, were studied. All these patients had been treated for diabetes for several years before the diagnosis of adrenal tumors. In each case the state of diabetes before and after surgery, including parameters of insulin secretion and insulin resistance, was compared to demonstrate how the adrenal disorder influenced the nature of diabetes. In the case of Cushing's syndrome the hypercortisolemia caused insulin resistance in the peripheral tissues. In the case of primary aldosteronism, excessive production of aldosterone diminished insulin secretion possibly through hypokalemia. pheochromocytoma affected both insulin secretion and insulin sensitivity through hypersecretion of catecholamines. In all these patients the adrenal tumors were found in clinical contexts other than management of diabetes itself. By careful retrospective review of these three patients' history, several important points that might have drawn the physician's attention to the underlying adrenal disorders were pointed out. These included past history of acute myocardial infarction with onset at unexpectedly young age in the case of Cushing's syndrome and unexpectedly high insulin resistance for the patient's body mass index in the case of pheochromocytoma.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
5/28. A case of pyoderma gangrenosum on the stump of an amputated right leg.We present here a case of pyoderma gangrenosum (PG) on the stump of an amputated leg. The patient was a 69-year-old woman who had both of her legs amputated due to acute arterial occlusion. An ulcer first appeared nine years later, after which point it continued to fluctuate in size. Complications included regional blood flow disorder at the amputated stump, diabetes, and secondary infection. Despite various therapies, the ulcer exacerbated, and hypoproteinemia, increased CRP, and fever were confirmed. The patient was diagnosed as having PG based on her clinical symptoms and because the ulcer did not respond to various therapies. The ulcer improved significantly in response to administration of 40 mg/day of prednisolone, and complete epithelialization was later achieved. Given the presence of multiple complications, it was extremely difficult to confirm PG. Therefore, it is important for physicians to consider PG as one of the causes of intractable ulcers.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
6/28. mtDNA disease in the primary care setting.Disorders of mitochondrial dna (mtDNA) may commonly present to primary care physicians but go undiagnosed. A 36-year-old man with a 15-year history of psychosis, seizures, and sensorineural hearing loss and a family history of diabetes mellitus and heart disease presented to our hospital without a unifying diagnosis. Physiologic, biochemical, and genetic testing revealed deficient aerobic metabolism, a defect in mitochondrial electron transport, and the presence of an A-to-G point mutation at position 3243 of the mitochondrial leucine-transfer rna gene, establishing the diagnosis of mitochondrial encephalopathy, lactic acidosis, and strokelike syndrome (MELAS). Diagnosing mtDNA disorders requires a careful integration of clinical signs and symptoms with pedigree analysis and multidisciplinary testing. diagnosis is important to provide genetic counseling, avoid unnecessary evaluation, and facilitate therapy for symptomatic relief.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
7/28. Oral antihyperglycemic therapy for type 2 diabetes: clinical applications.Oral agents are the mainstay of pharmacologic treatment for type 2 diabetes, and physicians now have a number of agents to choose from. However, more choices translate into more complex decision making. Many patients with diabetes have associated comorbidities, and most diabetic patients will require more than 1 agent to achieve good glycemic control. This article illustrates several of the pharmacologic approaches to type 2 diabetes through 4 situations that use principles of evidence-based medicine. The scenarios also highlight some of the difficulties in choosing the optimal pharmacologic treatment regimen for individual patients. physicians should also recognize that type 2 diabetes is a multisystem disorder that requires multidisciplinary care, including education and ongoing counseling for effective patient self-management of the disease. Finally, patient preferences are a vital component of informed decision making for pharmacologic treatment of diabetes.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
8/28. Diabetic neuropathy masquerading as glossodynia.BACKGROUND: Diabetic neuropathy, or DN, occurs in approximately 50 percent of patients who have type 2 diabetes mellitus, or DM. Oral burning and symptoms consistent with glossodynia (burning mouth syndrome) may occur secondary to DN. CASE DESCRIPTION: A 54-year-old woman reported to a university dental clinic with a chief complaint of oral burning. No clinical signs were evident. Her medical history was positive for type 2 DM. The initial diagnosis was glossodynia, and she was evaluated with relevant blood studies, which indicated that her diabetes was not well-controlled. The patient was referred back to her physician, and her symptoms abated once her diabetic condition was under control. CLINICAL IMPLICATIONS: It is important to consider DN within the differential diagnoses of patients who have symptoms consistent with glossodynia but have no clinical signs. dentists are invaluable in ascertaining underlying systemic disease considerations in patients with oral symptomatology. Cooperation between dentists and physicians often is helpful and necessary in caring for patients who have uncontrolled type 2 DM and oral symptoms.- - - - - - - - - - ranking = 0.5keywords = physician (Clic here for more details about this article) |
9/28. Using new insulin strategies in the outpatient treatment of diabetes: clinical applications.Understanding when to use insulin and how to apply the principles of physiologic insulin replacement using existing and new insulins is a key step to improving diabetes care. Insulin analogues and premixed insulins increase physicians' and patients' ability to lower hemoglobin A1C levels with fewer episodes of hypoglycemia. Earlier use of insulin and more aggressive dose escalation are important steps in achieving treatment goals. This article discusses using bedtime insulin with oral agents, basal-prandial insulin strategies, and the new insulin analogues.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
10/28. Biguanide-associated lactic acidosis. Case report and review of the literature.PURPOSE--The biguanides are a class of oral hypoglycemic agents that are commonly used in the treatment of diabetes mellitus. Such agents include metformin, phenformin, and buformin. The use of phenformin was discontinued in the united states in 1976 because of probable association with lactic acidosis. However, metformin is currently in common use in many parts of the world. In this report, we describe a patient with severe lactic acidosis secondary to metformin administration, and review the literature relevant to biguanide-associated lactic acidosis. PATIENT--We describe a diabetic man with end-stage renal failure and diabetes mellitus who was hospitalized with life-threatening lactic acidosis (lactate, 10.9 mmol/L). Unbeknownst to the hospital staff, he was being treated with metformin, which had been prescribed in indonesia. RESULTS--Arterial blood gas analysis revealed a pH of 6.76 and a bicarbonate level of 1.6 mmol/L prior to treatment. Following therapy, which included oxygen, volume expansion, other supportive therapy, and hemodialysis, the patient completely recovered and was discharged from the hospital. CONCLUSIONS--Lactic acidosis can complicate biguanide therapy in diabetic patients with renal insufficiency. We review the literature relevant to the pathogenesis and therapy of biguanide-associated lactic acidosis. physicians who have completed their training after 1976 may not be familiar with metformin and other biguanides, but with the increasing numbers of immigrants to the united states, physicians should be aware of the potential complications of these medications.- - - - - - - - - - ranking = 0.25keywords = physician (Clic here for more details about this article) |
