Warning regarding scam “Certification Boards”
ABIM has received reports from several of our diplomates regarding letters and solicitations they have received from groups offering “certification” in Geriatric Medicine, Cardiology and Hospital Medicine, among other things. ABIM is concerned about the welfare of patients who may choose doctors representing themselves as “board certified” based on their possession of a certificate from unaccredited “boards” that award certificates but require no accredited training, testing or medical background review. Have you been contacted by any of the following groups? These phony “medical boards” have been reported to ABIM as fraudulent, and if you hear from them, or receive any certification information that seems suspicious, ABIM would like to know about it.
If you have been approached by an organization calling itself a board that is not a member of ABMS or the American Osteopathic Association or has not established its status by state licensure board recognition, please e-mail security@abim.org for information on these possible “scams” and what can be done to assure the professional integrity of medical specialty certification.

Answer: Right pulmonary vein aneurysm (PVA)
Congenital PVA may progressively increase in size over the years and may rupture. Pulmonary venous aneurysm may occur as a component of congenital pulmonary arteriovenous malformation (PAVMN) or traumatic pulmonary arteriovenous pseuodoaneurysm (PAP). symptoms iclude hypoxia, congestive heart failure, hemoptysis and cerebral abscess. Pulmonary venous aneurysm may also be acquired and is known to be associated with rheumatic mitral insufficiency.
All these lesions may present as a mediastinal mass. Computed tomography, echocardiography and angiography usually help to differentiate from other vascular lesions.

Q: What is half life of Xigris - Recombinant Protein C (Activated) ?
A; Xigris has a short half-life, indicating rapid inactivation of Xigris after stopping infusion and more than 70% get eliminate within 30 minutes.
General recommendations are
- Discontinue Xigris 2 hours prior to performing an invasive procedure and may restart immediately after uncomplicated, less invasive procedures
- Initiation of Xigris can be considered 12 hours after major invasive procedures or surgery
- Prophylactic heparin/LMWH may be continued while patient is on xigris
Note:
- Xigris may variably prolong the APTT. Therefore, the APTT cannot be reliably used to assess the status of the coagulopathy during Xigris infusion.
- Xigris has minimal effect on the PT

Q: What percentage of patients may develop complications secondary to brachial artery cannulation?
Answer: upto 42%
It was established almost 40 years ago by Mortensen 1 that brachial artery cannulation is not an ideal location. The lack of collateral circulation about the elbow may predispose to forearm and hand ischemic complications.

Dexmedetomidine (precedex) Infusion as Adjunctive Therapy for Acute Alcohol Withdrawal
Emerging literature is very promising for Dexmedetomidine (precedex) Infusion as an adjunctive therapy to benzodiazepines in acute alcohol withdrawal.
Review of literature shows that dexmedetomidine was shown to be beneficial in alcohol withdrawal delirium first in rats about 10 years ago ! 4 but later many case series in humans have shown a rapid response to alcohol withdrawal delirium after the standard treatment. 1, 2, 3, 5 Dexmedetomidine is a selective alpha-2 adrenergic agonist that possesses a high ratio of specificity for the alpha-2 versus the alpha-1 receptor.
The biggest advantage of Dexmedetomidine over benzodiazepines in acute alcohol withdrawal therapy, is that it doesn't suppress respiratory drive and carries simultaneuos properties of analgesia, sedation and anxiolysis.
