Your Observations About the Man With the Tripod Sign

A 67-year-old woman arrived via ambulance in ventricular tachycardia. She had been experiencing crushing substernal chest pain and shortness of breath that had worsened over the past several hours. She received oxygen (by mask) and lidocaine (100 mg intravenously) en route to the emergency department (ED), but there was no change in the rhythm.

The diagnostic criteria for major depression are anhedonia, depressed mood, feelings of worthlessness or inappropriate guilt, inability to concentrate, fatigue, insomnia or hypersomnia, psychomotor agitation or retardation, significant weight loss or gain, and recurrent thoughts of death or suicide. Five or more of these symptoms must be present for at least 2 weeks, and one of them must be anhedonia or depressed mood. Conditions that can present with depression include dysthymia, bipolar disorder, cyclothymia, and adjustment disorder. Depression may also result from substance abuse or from the physiological conditions associated with a medical disorder, such as spinal or head injury, AIDS, or cancer.

LONDON -- A program of breathing and relaxation exercises known as the Papworth method eases the symptoms of asthma significantly -- largely without change in underlying lung function, researchers here said.

MINNEAPOLIS -- Selective serotonin reuptake inhibitors (SSRIs) have been linked to decreased bone density in older women and men, according to two related studies.

BOSTON -- Use of selective serotonin-reuptake inhibitors (SSRIs) during the first trimester of pregnancy did not significantly increase the risk of congenital heart defects overall, despite FDA and drug maker warnings to the contrary.

PHILADELPHIA -- Seven out of 10 patients with chronic insomnia never talk with their doctors about it. Instead, they self-medicate with over-the-counter medicines or alcohol.

AMSTERDAM, The Netherlands -- New users who took the street drug Ecstasy for a mean 1.6 months at low cumulative doses showed a decline in verbal recall and recognition.

BOSTON -- Suicidal tendencies that arise in some men who start on the antidepressant citalopram (Celexa) may be linked to genetic mutations, investigators in Boston and Dallas reported.

I am an adult psychiatric nurse practitioner, and a significant part of my practice has been the treatment of subclinical hypothyroidism. Whenever a patient has depression and low energy, I measure free T4, free T3, and thyroid-stimulating hormone (TSH) levels. In most of the subclinical hypothyroidism I have detected, the TSH level is normal. In many cases, the only level that is low is the free T3. When liothyronine is prescribed for these patients, their symptoms of depression and tiredness decrease and their need for antidepressants has, in a few cases, been eliminated.
