ABSTRACT: Procedures performed by an interventional radiology specialist are becoming increasingly important in the management of patients with cancer. Although general interventional radiology procedures such as angiography and angioplasty are used in patients with and without cancer, certain procedures are reserved for the diagnosis and treatment of cancer or cancer-related complications. Interventional radiology procedures include imaging-guided biopsies to obtain samples for cytologic or pathologic testing without affecting adjacent structures. Transjugular liver biopsy is used to diagnose hepatic parenchymal abnormalities without traversing Glisson's capsule. This biopsy procedure is particularly useful in patients with coagulopathies. Because the transjugular liver biopsy obtains random samples, it is not recommended for biopsy of discrete hepatic masses. Fluid collections can also be sampled or drained using interventional radiology techniques. Transcatheter chemoembolization is a procedure that delivers a chemotherapeutic agent to a tumor along with sponge particles that have an ischemic effect on the mass. Tumor ablation, gene therapy and access of central veins for treatment are performed effectively under radiographic guidance. Cancer complications can also be treated with interventional radiology techniques. Examples include pain control procedures, vertebroplasty and drainage of obstructed organs. Interventional radiology techniques typically represent the least invasive definitive diagnostic or therapeutic options available for patients with cancer. They can often be performed at a lower cost and with less associated morbidity than other interventions.
ABSTRACT: Treatment advances over the past 25 years have significantly decreased morbidity and mortality in children with sickle cell disease. Aggressive management of fever, early diagnosis of acute chest syndrome, judicious use of transfusions and proper treatment of pain can improve quality of life and prognosis for these children. Prophylactic hydroxyurea therapy has been shown to reduce the incidence and severity of pain crises in adults with sickle cell disease and has been effective in limited studies conducted in children. Research into stem cell transplantation provides hope that a cure for sickle cell disease may be possible.
Treatment of Knee Osteoarthritis - Article
ABSTRACT: Knee osteoarthritis is a common disabling condition that affects more than one-third of persons older than 65 years. Exercise, weight loss, physical therapy, intra-articular corticosteroid injections, and the use of nonsteroidal anti-inflammatory drugs and braces or heel wedges decrease pain and improve function. Acetaminophen, glucosamine, ginger, S-adenosylmethionine (SAM-e), capsaicin cream, topical nonsteroidal anti-inflammatory drugs, acupuncture, and tai chi may offer some benefit. Tramadol has a poor trade-off between risks and benefits and is not routinely recommended. Opioids are being used more often in patients with moderate to severe pain or diminished quality of life, but patients receiving these drugs must be carefully selected and monitored because of the inherent adverse effects. Intra-articular corticosteroid injections are effective, but evidence for injection of hyaluronic acid is mixed. Arthroscopic surgery has been shown to have no benefit in knee osteoarthritis. Total joint arthroplasty of the knee should be considered when conservative symptomatic management is ineffective.
ABSTRACT: Stress fractures are common injuries in athletes and military recruits. These injuries occur more commonly in lower extremities than in upper extremities. Stress fractures should be considered in patients who present with tenderness or edema after a recent increase in activity or repeated activity with limited rest. The differential diagnosis varies based on location, but commonly includes tendinopathy, compartment syndrome, and nerve or artery entrapment syndrome. Medial tibial stress syndrome (shin splints) can be distinguished from tibial stress fractures by diffuse tenderness along the length of the posteromedial tibial shaft and a lack of edema. When stress fracture is suspected, plain radiography should be obtained initially and, if negative, may be repeated after two to three weeks for greater accuracy. If an urgent diagnosis is needed, triple-phase bone scintigraphy or magnetic resonance imaging should be considered. Both modalities have a similar sensitivity, but magnetic resonance imaging has greater specificity. Treatment of stress fractures consists of activity modification, including the use of nonweight-bearing crutches if needed for pain relief. Analgesics are appropriate to relieve pain, and pneumatic bracing can be used to facilitate healing. After the pain is resolved and the examination shows improvement, patients may gradually increase their level of activity. Surgical consultation may be appropriate for patients with stress fractures in high-risk locations, nonunion, or recurrent stress fractures. Prevention of stress fractures has been studied in military personnel, but more research is needed in other populations.
Diagnosis of Heel Pain - Article
ABSTRACT: Heel pain is a common presenting symptom in ambulatory clinics. There are many causes, but a mechanical etiology is most common. Location of pain can be a guide to the proper diagnosis. The most common diagnosis is plantar fasciitis, a condition that leads to medial plantar heel pain, especially with the first weight-bearing steps in the morning and after long periods of rest. Other causes of plantar heel pain include calcaneal stress fracture (progressively worsening pain following an increase in activity level or change to a harder walking surface), nerve entrapment (pain accompanied by burning, tingling, or numbness), heel pad syndrome (deep, bruise-like pain in the middle of the heel), neuromas, and plantar warts. Achilles tendinopathy is a common condition that causes posterior heel pain. Other tendinopathies demonstrate pain localized to the insertion site of the affected tendon. Posterior heel pain can also be attributed to a Haglund deformity, a prominence of the calcaneus that may cause bursa inflammation between the calcaneus and Achilles tendon, or to Sever disease, a calcaneal apophysitis in children. Medial midfoot heel pain, particularly with continued weight bearing, may be due to tarsal tunnel syndrome, which is caused by compression of the posterior tibial nerve as it courses through the flexor retinaculum, medial calcaneus, posterior talus, and medial malleolus. Sinus tarsi syndrome occurs in the space between the calcaneus, talus, and talocalcaneonavicular and subtalar joints. The syndrome manifests as lateral midfoot heel pain. Differentiating among causes of heel pain can be accomplished through a patient history and physical examination, with appropriate imaging studies, if indicated.
ABSTRACT: The prevalence of end-stage renal disease continues to increase, and dialysis is offered to older and more medically complex patients. Pain is problematic in up to one-half of patients receiving dialysis and may result from renal and nonrenal etiologies. Opioids can be prescribed safely, but the patient’s renal function must be considered when selecting a drug and when determining the dosage. Fentanyl and methadone are considered the safest opioids for use in patients with end-stage renal disease. Nonpain symptoms are common and affect quality of life. Phosphate binders, ondansetron, and naltrexone can be helpful for pruritus. Fatigue can be managed with treatment of anemia and optimization of dialysis, but persistent fatigue should prompt screening for depression. Ondansetron, metoclopramide, and haloperidol are effective for uremia-associated nausea. Nondialytic management may be preferable to dialysis initiation in older patients and in those with additional life-limiting illnesses, and may not significantly decrease life expectancy. Delaying dialysis initiation is also an option. Patients with end-stage renal disease should have advance directives, including documentation of situations in which they would no longer want dialysis.
