George Michael, still breathless after pneumonia and tracheotomy, plans a show for his doctors (video)

Video: George Michael: This has been the worst month of my life. ShowBiz411.

A thin and visibly weak George Michael (48) told reporters outside his home in London that he wasn't supposed to speak for very long and was still recovering from a tracheotomy: "I got streptococca-something... It's a form of pneumonia and they spent three weeks keeping me alive basically," Michael said of the doctors in the Austrian hospital where the singer has been receiving treatment since he fell ill in November.

He added that he also wanted to hold a special show for the Austrian doctors who treated him. "I've spent the last 10 days since I woke up literally thanking people for saving my life."

SHAKE may be common in hospitals: Supplement-associated Hyperammonemia After Cachectic Episode

High-protein dietary supplements were started for 2 patients, who had a period of anorexia before hospital admission but no history of liver disease. Subsequent altered mental status with ataxia developed in both patients.

Hyperammonemia was noted, while liver function test results remained normal.

Removal of the high-protein dietary supplements led to reversal of symptoms and normalization of the ammonia level.

With the ubiquity of nutrition supplement use, SHAKE (supplement-associated hyperammonemia after c[k]achetic episode) syndrome may be common in modern hospitals.

Norepinephrine Causes Fewer Adverse Events Than Dopamine in the Treatment of Shock

Both dopamine and norepinephrine (Levophed) are recommended as first-line vasopressor agents in the treatment of shock. There is a continuing controversy about whether one agent is superior to the other.

Although there was no significant difference in the rate of death between patients with shock who were treated with dopamine as the first-line vasopressor agent and those who were treated with norepinephrine, the use of dopamine was associated with a greater number of adverse events.

Superficial Venous Thrombosis Linked to Increased Risk of "Deep" Venous Thromboembolism for Months

Superficial venous thrombosis (SVT) is perceived to have a benign prognosis.

Among 844 patients with SVT, 24.9% also had deep venous thrombosis (DVT) or symptomatic pulmonary embolism.

Among 600 patients without DVT or pulmonary embolism at inclusion who were eligible for 3-month follow-up, 10.2% developed thromboembolic complications at 3 months despite 90.5% having received anticoagulants:

- pulmonary embolism 0.5%
- DVT 2.8%
- extension of SVT 3.3%
- recurrence of SVT 1.9%

A substantial number of patients with SVT exhibit venous thromboembolism at presentation, and some that do not can develop this complication in the subsequent 3 months.
