What’s your diagnosis?

Thymic Carcinoma

Thymic carcinoma displays distinct morphology and biology, different in many ways from thymoma. It is composed of highly atypical cells with cytoarchitectural features of carcinoma similar to those seen in other organs. Although many lymphocytes can be seen in its stroma, they are of B cell type and mature T cell type; thymic carcinoma lacks the immature T cell lymphocytes of thymoma.
Thymic carcinoma is classically not associated with paraneoplastic syndromes such as myasthenia gravis. However, one study reported 22 cases of primary thymic epithelial neoplasms which showed combined features of thymoma and thymic carcinoma; the carcinoma and thymoma were either found synchronously, or carcinoma developed with a preexisting thymoma after 10 to 14 years.
Incidence Primary thymic carcinoma is a rare neoplasm. At the National Cancer Center of Tokyo, 17 cases were resected over a 29 year period, during which time 79 thymomas and 2500 lung cancers were treated.
Clinical and radiographic manifestations Primary thymic carcinoma is a tumor of adulthood (mean age of 46 to 54 years). Most patients complain of chest symptoms, including pain, cough, superior vena cava syndrome, or general symptoms such as fatigue, weight loss, anorexia; fewer than 10% of patients are asymptomatic. Chest radiographs and computed tomography show an anterior mediastinal mass infiltrating along the pleura or mediastinum, with frequent necrosis or rare calcifications.

New AACE guideline to achieve glycemic goals

Via AACE from J Davidson, P Jellinger, L Blonde, H Lebovitz, C Parkin (2005):

The new position statement is this: Even if the initial A1C is from 6 to 7%, you should start pharmacotherapy.

This aggressive treatment has proved that mortality diminishes considerably.

Enteryx injection can cause death

Boston Scientific ENTERYX Procedure Kits and Injector Single Packs .

via FDA Safety I nformation Alerts:

For those who haven’t consider endoscopic procdedures for the treatment of GERD, well, at least, you shouldn’t think in Enteryx treatment.

FDA and Boston Scientific notified healthcare professionals and patients about serious adverse events, including death, occurring in patients treated with ENTERYX, a liquid chemical polymer which is intended to be injected into the lower esophageal sphincter for treatment of gastroesophageal reflux disease. The serious adverse events involve unrecognized transmural injections of ENTERYX into structures surrounding the esophagus. On September 23, 2005, Boston Scientific issued a recall of all ENTERYX Procedure Kits and ENTERYX Injector Single Packs from commercial distribution. Physicians should stop injecting ENTERYX immediately and follow the manufacturer’s procedures for returning unused product. FDA also provided recommendations on avoiding future occurrences and advice for patients.

Last month, Aggravated Doc Surg has made an excellent review of this treatments and recalls.

Acetaminophen-aspirin-caffeine better than Sumatriptan in early migraine?

via Reuters Health and Headache 2005;45:973-982:

National Headache Foundation guidelines for abortive treatment of migraine aren’t right?

This study states that the combination of acetaminophen, aspirin, and caffeine (AAC) is superior to sumatriptan in migraine’s early treatment.

Goldstein et al, compared the combination treatment with 50mg sumatriptan in 171 subjects treated when the first symptoms ofmigraine occurred. Patients taking AAC experienced significantly greater pain intensityreduction than did those taking sumatriptan beginning 2 hours afterdosing and continuing throughout the 4-hour treatment period.

More patients in the AAC group experienced a sustained response and fewer patients in the AAC group required rescuemedication by 4 hours postdose.

This results suggests that migraine sufferers can use AACto treat their migraine episodes at the first sign of an attack.

In my very own personal experience i’ll rather preffer to use Sumatriptan. What do you think?

Link of Obstructive Sleep Apnea and Stroke/Death

We all know those evidence linking OSA to systemic hypertension (even if your patient is not obese), because the vasoconstriction and activation of renin-angiotensin-aldosterone axis. But now there is new evidence that OSA is an important risk factor for stroke.

A new observational cohort study of NEJM by Yaggi et al, states that OSA increases significantly the risk of stroke, TIA or sudden death.
