ABSTRACT: In February 2002, the Kidney Disease Outcome Quality Initiative of the National Kidney Foundation published clinical practice guidelines on chronic kidney disease. The first six of the 15 guidelines are of the greatest relevance to family physicians. Part I of this two-part article reviews guidelines 1, 2, and 3. Chronic kidney disease is defined by the presence of a marker of kidney damage, such as proteinuria (ratio of greater than 30 mg of albumin to 1 g of creatinine on untimed [spot] urine testing), or a decreased glomerular filtration rate for three or more months. Disease staging is based on the glomerular filtration rate. Evaluation should be directed at determining the type and severity of chronic kidney disease. Treatment goals include preventing disease progression and complications. The guidelines place special emphasis on the prevention and treatment of cardiovascular disease in patients with chronic kidney disease. Risk factors for chronic kidney disease include diabetes mellitus, hypertension, family history of chronic kidney disease, age older than 60 years, and U.S. racial or ethnic minority status. The guidelines recommend testing for proteinuria and estimating the glomerular filtration rate in patients at risk for chronic kidney disease. Family physicians should weigh the value of the National Kidney Foundation guidelines for their clinical practice based on the strength of evidence and perceived cost-effectiveness until additional evidence becomes available on the usefulness of the recommended quality indicators.
ABSTRACT: The development of newer classes of antidepressants and second-generation antiepileptic drugs has created unprecedented opportunities for the treatment of chronic pain. These drugs modulate pain transmission by interacting with specific neurotransmitters and ion channels. The actions of antidepressants and antiepileptic drugs differ in neuropathic and non-neuropathic pain, and agents within each medication class have varying degrees of efficacy. Tricyclic antidepressants (e.g., amitriptyline, nortriptyline, desipramine) and certain novel antidepressants (i.e., bupropion, venlafaxine, duloxetine) are effective in the treatment of neuropathic pain. The analgesic effect of these drugs is independent of their antidepressant effect and appears strongest in agents with mixed-receptor or predominantly noradrenergic activity, rather than serotoninergic activity. First-generation antiepileptic drugs (i.e., carbamazepine, phenytoin) and second-generation antiepileptic drugs (e.g., gabapentin, pregabalin) are effective in the treatment of neuropathic pain. The efficacy of antidepressants and antiepileptic drugs in the treatment of neuropathic pain is comparable; tolerability also is comparable, but safety and side effect profiles differ. Tricyclic antidepressants are the most cost-effective agents, but second-generation antiepileptic drugs are associated with fewer safety concerns in elderly patients. Tricyclic antidepressants have documented (although limited) efficacy in the treatment of fibromyalgia and chronic low back pain. Recent evidence suggests that duloxetine and pregabalin have modest efficacy in patients with fibromyalgia.
ABSTRACT: Primary care physicians should have a working knowledge of rheumatic diseases of childhood that manifest primarily as musculoskeletal pain. Children with juvenile rheumatoid arthritis can present with painless joint inflammation and may have normal results on rheumatologic tests. Significant morbidity may result from associated painless uveitis, and children with juvenile rheumatoid arthritis should be screened by an ophthalmologist. The spondyloarthropathies (including juvenile ankylosing spondylitis and reactive arthritis) often cause enthesitis, and patients typically have positive results on a human leukocyte antigen B27 test and negative results on an antinuclear antibody test. Patients with acute rheumatic fever present with migratory arthritis two to three weeks after having untreated group A beta-hemolytic streptococcal pharyngitis. Henoch-Schbnlein purpura may manifest as arthritis before the classic purpuric rash appears. Systemic lupus erythematosus is rare in childhood but may cause significant morbidity and mortality if not treated early. Nonsteroidal anti-inflammatory drugs and physical therapy may be useful early interventions if a rheumatic illness is suspected. Family physicians should refer children when the diagnosis is in question or subspecialty treatment is required. Part I of this series discusses an approach to diagnosis with judicious use of laboratory and radiologic testing.
ABSTRACT: Herbs, vitamins, and other dietary supplements may augment or antagonize the actions of prescription and nonprescription drugs. St. John's wort is the supplement that has the most documented interactions with drugs. As with many drug-drug interactions, the information for many dietary supplements is deficient and sometimes supported only by case reports. Deleterious effects are most pronounced with anticoagulants, cardiovascular medications, oral hypoglycemics, and antiretrovirals. Case reports have shown a reduction in International Normalized Ratio in patients taking St. John's wort and warfarin. Other studies have shown reduced levels of verapamil, statins, digoxin, and antiretrovirals in patients taking St. John's wort. Physicians should routinely ask patients about their use of dietary supplements when starting or stopping a prescription drug, or if unexpected reactions occur.
ABSTRACT: Shoulder pain is defined as chronic when it has been present for longer than six months. Common conditions that can result in chronic shoulder pain include rotator cuff disorders, adhesive capsulitis, shoulder instability, and shoulder arthritis. Rotator cuff disorders include tendinopathy, partial tears, and complete tears. A clinical decision rule that is helpful in the diagnosis of rotator cuff tears includes pain with overhead activity, weakness on empty can and external rotation tests, and a positive impingement sign. Adhesive capsulitis can be associated with diabetes and thyroid disorders. Clinical presentation includes diffuse shoulder pain with restricted passive range of motion on examination. Acromioclavicular osteoarthritis presents with superior shoulder pain, acromioclavicular joint tenderness, and a painful cross-body adduction test. In patients who are older than 50 years, glenohumeral osteoarthritis usually presents as gradual pain and loss of motion. In patients younger than 40 years, glenohumeral instability generally presents with a history of dislocation or subluxation events. Positive apprehension and relocation are consistent with the diagnosis. Imaging studies, indicated when diagnosis remains unclear or management would be altered, include plain radiographs, magnetic resonance imaging, ultrasonography, and computed tomography scans. Plain radiographs may help diagnose massive rotator cuff tears, shoulder instability, and shoulder arthritis. Magnetic resonance imaging and ultrasonography are preferred for rotator cuff disorders. For shoulder instability, magnetic resonance imaging arthrogram is preferred over magnetic resonance imaging.
ABSTRACT: A systematic approach to chronic nonmalignant pain includes a comprehensive evaluation; a treatment plan determined by the diagnosis and mechanisms underlying the pain; patient education; and realistic goal setting. The main goal of treatment is to improve quality of life while decreasing pain. An initial comprehensive pain assessment is essential in developing a treatment plan that addresses the physical, social, functional, and psychological needs of the patient. One obstacle to appropriate pain management is managing the adverse effects of medication. Opioids pose challenges with abuse, addiction, diversion, lack of knowledge, concerns about adverse effects, and fears of regulatory scrutiny. These challenges may be overcome by adherence to the Federation of State Medical Boards guidelines, use of random urine drug screening, monitoring for aberrant behaviors, and anticipating adverse effects. When psychiatric comorbidities are present, risk of substance abuse is high and pain management may require specialized treatment or consultation. Referral to a pain management specialist can be helpful.

ABSTRACT: Chronic liver disease is the 10th leading cause of death in the United States. Hepatitis C virus infection is the most frequent cause of chronic liver disease and the most common indication for liver transplantation. Preventive care can significantly reduce the progression of liver disease. Alcohol and hepatitis C virus are synergistic in hastening the development of cirrhosis; therefore, patients with hepatitis C infection should abstain from alcohol use. Because superinfection with hepatitis A or B virus can lead to liver failure, vaccination is recommended. Potentially hepatotoxic medications should be used with caution in patients with chronic liver disease. In general, nonsteroidal anti-inflammatory drugs should be avoided; acetaminophen in a dosage below 2 g per day is the safest choice. Many herbal remedies are potentially hepatotoxic, and only milk thistle can be used safely in patients who have chronic liver disease. Weight reduction and exercise can improve liver function in patients with fatty liver.
