Rudolph the red-nosed reindeer

Rudolph - probably the best known reindeer in the world - but do you know the other reindeers' names (see below for answer).

Rudolph first appeared in a 1939 booklet written by RL May.

His spouse's name is 'Clarice', and BBC has made a show on his son "Robbie the Reindeer". His brother "Rusty the Reindeer" appeared in a 2006 TV show in the US.

In 2012 Rudolph appeared as the frontcover of the British Journal of Surgery, albeit in a more anatomical figure than usually seen:

One big question has never been answered over the years though: 

Why is Rudolph's nose red?

The scientific explanation to why Rudolph has a red nose is now clear. A recent research paper in the BMJ has investigated this and found that Rudolph’s nose is red because it is richly supplied with red blood cells, comprises a highly dense microcirculation, and is anatomically and physiologically adapted for reindeer to carry out their flying duties for Santa Claus.

The names of the other 8 reindeers are:

Dasher, Dancer, Prancer Vixen, Comet, Cupid, Donder and Blitzen.

Medical info - collecting and curation in the internet era

Never has there been a larger stream of info available for humankind. Getting access to info is not the problem anymore, rather the selection, digestion and prioritizing of info is the key skills needed in modern information overload.

Notably, PubMed alone has now grown to include over 22 million references!

On this week's cover, the Science Translational Medicine new "Collections icons" are shown as if they were apps on a smart phone, linking users to the information they seek. Editor-selected highlights from the journal are grouped by subject to form more than 50 collections on topics such as cancer, biomarkers, vaccines, partnerships, and bioengineering, pluss many more; go see the web @  SciTM Collections.

Acute pancreatitis reclassified - twice!

Acute pancreatitis is a fairly common disease mot often caused by either gallstone disease or alcohol, with a number of other causes involved as well. The natural history may be unpredictable - mild disease usually resolves without any or just little medical support, while severe disease may involve into several complications, need for organ support and intensive care, and have a mortality as high as 30%.
Predicting which patient will develop severe disease is difficult, with a number of scoring systems proposed over the years; the Ranson score, Imrie (or Glasgow) score, the Harmless Acute Pancreatitis Score (HAPS), the APACAHE II score, JSS, BISAP, SIRS, Panc, POP, and so on...
However, noen of these work perfectly - the clinical prediction riles have reached their limitation (see Mounzer, Gastroenterology, 2012).

Disease severeity and classification of acute pancreatitis have been based on the Atlanta consensus from 1992. Several components of this classification have been controversial and critized over the years, and several research groups have argued for better definitions in order to compare results between studies and generate commonly agreed definitions for conducting trials.

This work has over the past several years come to fruition through two released international consensus reports:

One from the "Acute Pancreatitis Classification Working Group"

Banks PA, Bollen TL, Dervenis C, Gooszen HG, Johnson CD, Sarr MG, Tsiotos GG, Vege SS; Acute Pancreatitis Classification Working Group. Classification of acute pancreatitis--2012: revision of the Atlanta classification and definitions by international consensus. Gut. 2012 Oct 25. [Epub ahead of print]


and the other one from the PANCREA group

Dellinger EP, Forsmark CE, Layer P, Lévy P, Maraví-Poma E, Petrov MS,Shimosegawa T, Siriwardena AK, Uomo G, Whitcomb DC, Windsor JA; Pancreatitis Across Nations Clinical Research and Education Alliance (PANCREA). Determinant-Based Classification of Acute Pancreatitis Severity: An International Multidisciplinary Consultation. Ann Surg. 2012 Dec;256(6):875-880.

The consensus reports will hopefully allow for commonly agreed terms and definitions for future research. A problem is obviously that the two reports divert somewhat in their agreement in the number of categories neede for classifying acute pancreatitis. In the Gut paper the authors have defined a 3-tier system og mild, moderate and severe pancreatitis. The Annals paper have added a fourth group, named crititcal acute pancreatitis, when organ failure persists WITH the addition of infected (peri)pancreatic necrosis.

The Gut paper has emphasized several agreed terms and definitions for radiological classification of early (<4 weeks) and late (>4 weeks) fluid collections (such as "acute peripancreatic fluid collection; APFC" and "walled off necrosis; WON") to be distinguished from other terms such as "pseudocysts" and the now abandonded term "pancreatic abcess".

Which of the two suggestions will prevail over the other remains to be seen.

Cartoon commercials

I have to admit I do not remember the name of the artist to be credited for this, so if anyone coul dhelp me post his/her name for credits it would be great. However, the artistic work focuses on health problems related to the consumerism seen with certain products - I think the pictures really do speak for themselves.

Sutureless mesh for hernia repair - RCT in BJS

Hernia repair is one of the most commonly performed surgical procedures worldwide. The number of surgical techniques and available equipment is considerable and several alternatives have been introduced and suggested over the years. Common to them all is that none is "perfect", and complication rates - most commonly discomfort and pain (up tp 15-20% of patients ) and hernia recurrence (up to 10-15%) continues to be a problem.

Resorbable polylactic acid (PLA) microgrips, from Covidien

A recent sutureless mesh was introduced by Covidien (Parietene ProGrip TM) with the idea that this would 
Now the DANGRIP Study Group have performed a randomized multicentre clinical trial comparing a self-gripping mesh (Parietene Progrip^®) and sutured mesh for open primary repair of uncomplicated inguinal hernia by the Lichtenstein technique. Patients were assessed before surgery, on the day of operation, and at 1 and 12 months after surgery. The primary endpoint was moderate or severe symptoms after 12 months, including a combination of chronic pain, numbness and discomfort.

The intention-to-treat population comprised 163 patients with self-gripping mesh and 171 with sutured mesh. The 12-month prevalence of moderate or severe symptoms was 17·4 and 20·2 per cent respectively (P = 0·573). There were no significant differences between the groups in postoperative complications (33·7 versus 40·4 per cent; P = 0·215), rate of recurrent hernia within 1 year (1·2 per cent in both groups) or quality of life.

The authors conclude that, the avoidance of suture fixation using a self-gripping mesh was not accompanied by a reduction in chronic symptoms after inguinal hernia repair.
