Levothyroxine is one of the most commonly prescribed medications for the treatment of hypothyroidism as well as the suppression of thyroid neoplasms.1 Most patients with hypothyroidism require lifelong therapy with levothyroxine; therefore, the likelihood of drug interactions is high.
My patient is a man in his early 70s who complains of lack of strength. His testosterone level is low, and his B12 level is low-normal.
A 28-year-old woman presents with milky discharge in both breasts and throbbing occipital headaches of 4 months' duration. The headaches begin gradually, do not radiate, and have no apparent triggers or relieving factors.
Pain is a significant public health concern. In a prevalence study conducted in Australia, 17% of men and 20% of women reported chronic daily pain. A US study found that 13% of the total workforce had lost productive time during a 2-week period because of a pain condition. Headache, back pain, and arthritis pain headed the list of causes.
The recent "Consultations & Comments" exchange titled "What Cause of Cold and Flushing in a Basketball Player?" (CONSULTANT, November 2007) attracted my attention.
A 62-year-old man presents with painful cramps in his left lower leg that began about 6 months earlier and have recently become more frequent. The cramps occur with vigorous walking and cease when he stops for several minutes.
Nephropathy develops in about 30% of patients with diabetes. Screen for albuminuria at the time type 2 diabetes is diagnosed and within 5 years of diagnosis of type 1 diabetes.
Determining the cause of generalized weakness can be a daunting task, since the differential diagnosis is vast. An overall approach to the patient who complains of generalized weakness is presented in our article
The differential diagnosis of generalized weakness is enormous; it includes disorders at all levels of the neur-axis. A variety of electrophysiological, pathological, radiographic, and other laboratory studies may be indicated depending on the specific diagnostic possibilities; costs can be controlled if such investigations are selected judiciously.
Identifying the cause of a persistent, asymptomatic aminotransferase elevation can be challenging. The possible diagnoses are many and varied. To narrow the differential, begin with a detailed history.
Treatment of hypertension can minimize both microvascular and macrovascular complications of diabetes and helps prevent nephropathy and cardiovascular events.
Sometimes, despite compliance with prescribed thyroid medication, a patient's thyroid-stimulating hormone (TSH) level remains high.
For 2 weeks, a 43-year-old white female had worsening nausea and multiple episodes of vomiting. Her symptoms began with increased malaise and decreased appetite. The emesis was unrelated to meals and was sometimes accompanied by mild abdominal distention. She had occasional fevers but denied any recent contact with ill persons. She also reported a 12-lb weight loss, decreased energy level, and an increased tan complexion over the past several months.
A 66-year-old woman was hospitalized because of severe anemia secondary to myelodysplastic syndrome. She had had associated fatigue and throbbing pain in both legs for several days.
Worsening painful ulcers on both legs prompted a 62-year-old woman to seek medical attention. She had a history of rheumatoid arthritis (RA), demonstrated by the markedly deformed interphalangeal joints in her thumbs (A), and scleroderma-polymyositis overlap syndrome.
A 74-year-old woman presented with a refractory pruritic eruption. Four months earlier, she had sought evaluation of a thickened, slightly crusted 6 3 8-cm patch on her right ankle of 2 months' duration. Contact dermatitis with secondary impetigo from scratching was suspected, and a topical corticosteroid and an oral antibiotic were prescribed.
Over the past 20 years, the treatment armamentarium for diabetes has greatly expanded: 8 different classes of non-insulin drugs and 8 different types of insulin are now available. The newer classes of agents include disaccharidase inhibitors, thiazolidinediones, meglitinides, glucagonlike peptide analogs, and dipeptidyl peptidase IV inhibitors.
BOURNEMOUTH, England-A campaign to urge kids to stop drinking sugared carbonated beverages-an effort to have them lose weight or prevent obesity-didn’t seem to have much value in the long run, reported investigators here.
WACOL, Australia-Schizophrenia leads to an age-related mortality rate that is about 2.5 times that of the general population, and the difference appears to be increasing, researchers here reported.
Here: a look at the many possible causes of poorly controlled blood glucose levels, and steps to overcome them.
ROCHESTER, NY-Breast cancer patients with a history of traumatic or stressful life events have a significantly increased risk of recurrent disease, investigators here have found.
DENVER-A higher intake of omega-3 fatty acids found in fish was linked to a lower risk of pancreatic islet autoimmunity in children at genetic risk for type 1 diabetes, according to a preliminary study.
SAN FRANCISCO-Oncologists may be able to predict which breast cancer patients need and will respond to systemic therapies with a single genomic profiling assay, researchers said.
SAN FRANCISCO-Biology, rather than access, income, or education, is the major driver of the well-known racial differences in breast cancer outcome, researchers reported here.
ABSTRACT: Low-density lipoproteins are the most common atherogenic particles in diabetic dyslipidemia; therefore statins, which dramatically reduce low-density lipoprotein (LDL) cholesterol, are first-line therapy for patients with diabetes. These agents produce equivalent relative risk reductions in those with and without diabetes but confer greater absolute risk reduction because of the increased incidence of ischemic cardiovascular events in those with diabetes. The LDL cholesterol goal for patients with diabetes who do not have coronary heart disease is below 100 mg/dL. For secondary prevention, the goal is below 70 mg/dL. High-dose statin therapy may be required to achieve these goals. Fibric acids are a reasonable initial option for patients with triglyceride levels above 200 mg/dL and high-density lipoprotein (HDL) cholesterol levels below 40 mg/dL; in such patients they reduce risk as effectively as statins. Intermediate-release niacin raises HDL cholesterol levels; the effect is enhanced when niacin is combined with a statin.
