Faceless Man


I spent a day by the river 
It was quiet and the wind stood still 
I spent some time with nature 
To remind me of all that's real 
It's funny how silence speaks sometimes when you're alone 
And remember that you feel 
Again I stand against the Faceless Man 
Now I saw a face on the water 
It looked humble but willing to fight 
I saw the will of a warrior 
His yoke is easy and His burden is light 
He looked me right in the eyes 
Direct and concise to remind me 
To always do what's right 
Again I stand against the Faceless Man 
'Cause if the face inside can't see the light 
I know I'll have to walk alone 
And if I walk alone to the other side 
I know I might not make it home 
Again I stand against the Faceless Man 
Next time I see this face 
I'll say I choose to live for always 
So won't you come inside And never go away

سایش های روزمره

امروز در دپارتمان فارماکولوژی بودم برای یک جلسه و انتخاب ژورنال برای مقاله تصمیم  گیری قطعی را هنوز انجام ندادم
در حقیقت جلسه کوتاه و تنش زا یی بود
به تدریج می اموزم که خیلی وقت و انرزی را در سایش با انسان های  درجه دو (از نظر حرفه ای) هدر ندهم
یک دغدغه ی بزرگ من همکاران جوانترم بودند که برای پروژه استروژن  اضافه شده اند
این همه سختی باید پاداش درخوری هم در پی داشته باشد

Baby With Asthma and Vomitting






at first glance some more probable differentials outshine:
Esophageal Duplication,Esophageal Atresia,Neurogenic Tumor,Vascular Anomaly,Foreign Body


But lets take a look at the patient's CT images:











Now we have a more precise image of the underlying abnormality. 
which is the most likely diagnosis ?
a.Double Aortic Arch
b.Right Aortic Arch with aberrant left subclavian artery
c.Left Aortic Arch with aberrant right subclavian artery
d.Transposition of great vessels
e.Tetralogy of Fallot
-----------------------------------------------------------------------------------------------------------


Findings :


CXR: Mild indentation of the right distal aspect of the trachea. Barium swallow: There is an abnormal indentation of the posterior esophagus
CT: Right aortic arch with aberrant left subclavian artery coursing behind the esophagus and compressing it. This is consistent with a vascular ring. The aorta descends on the right and then crosses to the left at the level of the crus. Trachea is mild to moderately narrowed at the level of the vascular ring.


Diagnosis:  Right aortic arch with aberrant left subclavian artery (left SCA)

Discussuion:
  • Right arch is present in 0.1% of asymptomatic population
  • 10-15% with associated congenital heart disease (tetralogy of fallot most common) compared to patients with mirror image branching type of right aortic arch who have >90% chance of having associated congenital heart disease
  • May present with symptoms (stridor, dysphagia, cough), but most are asymptomatic
  • Most common congenital anomaly of aortic arch
  • Related to embryological persistence of the right fourth aortic arch
  • Diverticulum of Kommerell is dilatation of origin of left SCA (occurs in 60% of right arch with aberrant left SCA)
  • Left SCA can arise directly from the descending aorta or can arise from diverticulum of Kommerell)
  • The left ductus persists as ligamentum arteriosum, which completes the vascular ring
    • Left ligamentum arteriosum connects to subclavian artery= loose vascular ring
    • Left ligamentum arteriosum connects to diverticulum of Kommerell= tight vascular ring (constricting, symptomatic)
Treatment:
  • Right arch with aberrant left SCA and constricting (symptomatic) left ligamentum arteriosum: Division of ligamentum via left thoracotomy








Radiological overview:
  • Aortic arch located to right of trachea, coursing over right main stem bronchus
  • Large vessel arising from the distal aorta and passing behind the esophagus with oblique course to the left
  • In 60% there is dilatation of the origin of the aberrant subclavian artery (aortic diverticulum of Kommerell)
  • Aorta descends on right and crosses to left before entering abdomen
  • 4 branches off aortic arch: Right subclavian artery, right carotid artery, left carotid artery, left subclavian artery
  • CXR:
    • Aortic arch indentation on right of trachea, which is deviated to the left
    • Increased right paravertebral soft tissue density
    • Right-sided descending aorta line
    • Lateral shows indentation on the posterior aspect of the trachea
    • There may be prominence of the left mediastinum
  • Barium swallow:
    • Frontal view: Oblique filling defect coursing from right-inferior to left-superior
    • Lateral view: Posterior indentation
  • CT: Define patency of arch segments, branching patterns, depict constricting effect on tracheal airway, if present
  • Indications for additional imaging:
    • Right arch with airway compression and aberrant left SCA on esophagram: Perform cross-sectional imaging
    • Right arch, mirror image branching pattern: Evaluate for congenital heart disease

Key points:
  • Most common congenital anomaly of aortic arch
  • 10-15% with congenital heart disease
  • Most asymptomatic
  • Vascular ring formed by ligamentum arteriosum connecting to left subclavian artery or diverticulum of Kommerell
  • Aberrant left subclavian courses behind the esophagus
  • Right aortic arch courses over right main stem bronchus

Football : An Empty Pleasure


An article written by Mario Vargas Llosa in Nou Camp 1982;dissecting the entertaining might of Football ,as it meets the characteristics of a innocuous ,ephemeral and non-transcendent entertainment.
Pedram 


A couple of years ago, I heard the Brazilian anthropologist Roberto da Matta give a brilliant lecture in which he explained that the popularity of football expresses an innate desire for legality, equality and freedom.
His argument was clever and amusing. According to him, the public sees football as a sort of model society-one governed by clear and simple laws which everyone understands and observes and which, if violated, bring immediate punishment to the guilty party. A football field is an egalitarian space which excludes all favouritism and privilege. Here, on this grass marked out by white lines, a person is valued for what he is: for his skill, dedication, inventiveness and effectiveness. Names, money and influence count for nothing when it comes to scoring goals and earning the applause or whistles from the stands. The football player exercises the only form of freedom that society can allow its members if it is not to come apart: to do whatever they please as long as it is not prohibited by rules that everyone accepts.
This is what, in the end, stirs the passions of the crowds that, the world over, pour into the grounds, follow games on television with rapt attention and fight over their football idols: the secret envy, the unconscious nostalgia for a world that -unlike the one they live in, which is full of injustice, corruption, lawlessness and violence-offers harmony, law and equality.
Could this beautiful theory be true? Would that it were, for nothing could be more positive for the future of humanity than to have these civilised feelings nestling in the instinctive depths of the crowds. But, as usual, reality overtakes theory-showing it up as incomplete. Theories are always rational, logical, intellectual (even those theories that propose irrationality and madness); but in society, in human behaviour, the unconscious, unreason and pure spontaneity will always play a part. This is both inevitable and immeasurable.
I’m scribbling these lines in a seat in the Nou Camp, a few minutes before the Argentina-Belgium game that is kicking off this World Cup (Spain 1982). The signs are favourable: a radiant sun; an impressive multi-coloured crowd full of waving Spanish, Catalan, Argentine and a few Belgian flags; noisy fireworks; a festive atmosphere and applause for the dancing and gymnastic displays which are a warm-up to the game.
This is a much more appealing world than the one left outside, behind the Nou Camp stands and the people applauding the dances and patterns made by dozens of young people on the pitch. This is a world without wars, such as those in the South Atlantic and Lebanon, which the World Cup has relegated to second place in the minds of millions of fans throughout the world; they, like those of us here in the stands, will be thinking of nothing else in the next two hours except the passes and the shots of the 22 Argentine and Belgian players who are opening the tournament.
Perhaps the explanation for this extraordinary contemporary phenomenon, the passion for football-a sport raised to the status of a lay religion, with the greatest following of all-is in fact a lot less complicated than sociologists and psychologists would have us suppose; football might simply offer people something they can scarcely ever have: an opportunity to have fun, to enjoy themselves, to get excited, to feel certain intense emotions that daily routine rarely offers them.
To want to have fun, to enjoy ourselves, to have a good time, is a most legitimate aspiration-a right as valid as the desire to eat and work. For many, doubtless complex reasons, football in the world today has taken on this role with more success than any other sport.
Those of us who get pleasure from football are not in any way surprised at its great popularity as a collective entertainment. But there are many who do not understand it and even criticise it. They see it as deplorable because, they say, football alienates and impoverishes the masses-distracting them from important issues. Those who think like this forget that it is important to have fun. They also forget that what characterises entertainment, however intense and absorbing (and a good game of football is enormously intense and absorbing), is that it is ephemeral, non-transcendent, innocuous. An experience where the effect disappears at the same time as the cause. Sport, for those who enjoy it, is the love of form, a spectacle that does not transcend the physical, the sensory, the instant emotion; a spectacle that, unlike a book or a play, scarcely leaves a trace in the memory and does not enrich or impoverish knowledge. This is its appeal: it is exciting and empty. For that reason, intelligent and unintelligent, cultured and uncultured people can equally enjoy football. But that’s enough for now. The King has arrived. The teams have come out. The World Cup has been officially opened. The game is beginning. That’s enough writing. Let’s enjoy ourselves a bit.

Street Life,Street Death

Here's an interesting Economist article about HIV/AIDS management in critical areas.It reveals how a derogatory attitude  hampers the fight to curb the spread of AIDS.
Pedram
At a glance, the calf-length cape that a good-looking young model swirled around on stage appeared to be made of shaggy sheepskin, wildly inappropriate for the tropical climate of Pattaya, a seaside resort in Thailand. In fact its composition was more apt, if no less uncomfortable: hundreds of dangling prophylactics. Pattaya has one of Thailand’s highest concentrations of go-go bars, massage parlours and other shop windows for the sex trade. Parts of it call to mind Sodom-on-Sea. But this “Condom Fashion Show” was not part of the sleaze. It was staged at a recent United Nations-led “consultation”. The theme—sex workers and HIV, the virus that causes AIDS—was deadly serious, and the effort to turn it into burlesque rather heroic.
The consultation differed in more fundamental ways from the usual run of international conferences. Several dozen sex workers from eight countries (Cambodia, China, Fiji, Indonesia, Myanmar, Pakistan, Papua New Guinea and Thailand) attended as full-fledged participants, not just models in the fashion show. Sex workers are on the front line in the struggle against an epidemic that in Asia still claims 350,000 new infections each year. A 2008 report prepared for the United Nations by an independent commission confirmed that men who buy sex are the single-most powerful driving force in Asia’s HIV epidemics.” It is thought that about 10m Asian women sell sex to 75m men, who in turn have a further 50m regular partners.
A simple and effective way to cut HIV transmission is to ensure that sex workers have access to condoms, know how to use them and always do so. Yet the UN estimates that only a third of Asia’s sex workers are reached by HIV-prevention programmes. And in some countries possession of condoms is taken as evidence of involvement in prostitution, and hence a cause for harassment, extortion or detention.
Yet sex workers themselves are normally excluded—or exclude themselves—from the air-conditioned conference halls where officials and NGOs discuss their plight. One reason is a poor grasp of English, a language, one male Thai sex worker complained, that “we learned only from our clients”. More importantly, sex workers often suffer from official disdain or condescension and are seen as the problem, not the solution.
Of course, the sex industry has not been ignored in the battle against AIDS. Thailand’s early successes are perhaps best-known. It was the first country in Asia to launch a “100% condom-use programme” in the early 1990s, and it managed to cut HIV prevalence sharply. The danger now is of complacency.
The best prevention schemes involve sex workers themselves. As a Chinese delegate put it, given the chance they do a far better job of educating and helping peers than do the UN or government. Myanmar, not normally cited as an outpost of progressive policy, has an HIV-prevention scheme seen as a model. Population Services International, an international NGO, has set up a “peer-to-peer” network with 18 drop-in centres around the country. There, 350 staff, mostly former or present sex workers themselves, dispense advice, discounted condoms and treatment for sexually transmitted infections. HIV prevalence among sex workers dropped from over 30% in 2000-06 to 18% in 2008.
Still, a Burmese sex worker made a passionate intervention at the conference lamenting the stigma her profession carries. In Myanmar as elsewhere, sex workers suffer at the hands of the authorities. And the worst perpetrators are often the police and other official protectors. Take Cambodia, recognised for bringing down HIV prevalence, partly through a condom-use programme. In 2008 a law on “the Suppression of Human Trafficking and Sexual Exploitation” led to the closure of brothels and a shift of the sex trade to bars and other places, complicating measures to prevent HIV. Worse, Human Rights Watch says, it has helped the police to beat, rob and rape sex workers “with impunity”.
A group of Cambodians wrote: “Our lives and our industry have been ruined by the anti-trafficking industry. We used to work in a brothel where we have safety and solidarity… Now we are scattered on the street where it is more dangerous.”
This is an extreme example of two problems besetting efforts to help sex workers. One is that, in most places, sex work is illegal, and almost everywhere frowned upon. Indonesian delegates complained that a new “Puritanism” accompanying a slow Islamisation of public life is forcing the sex trade underground and so making it more dangerous. As our debate showed, arguments for and against decriminalising prostitution are fierce and complex. But as long as it remains a criminal act, sex workers will be vulnerable to arbitrary abuse.
Second, the debate about sex work has become drowned in a campaign against human trafficking. That campaign, however justified its goals, fosters an assumption that all sex workers ply their trade against their will. Yet most migrant sex workers have left home for good reasons of their own—among them a desire to work away from their families, and to earn more money.
Parts of the debate, such as terminology, are as old as the oldest profession. One side regards “sex worker” as a dangerously obfuscatory euphemism. The other sees “prostitute” as degrading and derogatory. One sees those who sell sex inevitably as the victims of exploitation. But those seeking to be heard in Pattaya wanted recognition as independent actors who have made their own choices. They demand to be treated with basic human dignity just as they are.

Artful Shtick


So it was all a storm in a tea cup. A little tantrum. A cry for attention. Call it what you will, but Wayne Rooney’s dramatic about-face over his decision not to sign a new deal with Manchester United caught us all on the hop and left this particular journalist dumbfounded as to why his dirty laundry was ever aired in public.
A day ago Wayne Rooney was on his way to becoming a pariah at Old Trafford, not just for rejecting the offer of a new contract, but for damning the club as un-ambitious and a spent force in terms of its ability to sign big name players and win major trophies. Wazza was on his way to Real Madrid, Manchester City, Barcelona, or Chelsea, take your pick, and was destined to be a target for the Red Devils’ boo boys for the rest of his career.
So what happened? Did Sir Alex Ferguson, already earmarked as “a genius” by Rooney in the midst of all the kerfuffle, work his magic again? Well that’s what Wazza says, though can we believe him after the schizophrenics of the last few days?
“I said on Wednesday the manager's a genius and it's his belief and support that convinced me to stay." Rooney said. "I'm delighted to sign another deal at United. I've spoken to the manager and the owners and they've convinced me this where I belong.”
"I am signing a new deal in the absolute belief that the management, coaching staff, board and owners are totally committed to making sure United maintains its proud winning history - which is the reason I joined the club in the first place.”
Uhm, excuse me Wazza, but didn’t you have the self same conversation before announcing your departure? And didn’t you then draw exactly the opposite conclusions? And if you were so undecided about your feelings why not keep quiet about it? After all, your current contract isn’t up until the summer of 2012 so you had time.


Here’s what I think happened, and this is pure speculation just for the fun of it, Rooney got played.
I don’t believe for a second that he’s changed his mind about United. I think his initial conclusions about the club’s lack of ambition and ability to attract top players were wrong, but I firmly believe that that’s what he thought, and that‘s what he still thinks ( or will once he lays down in bed tonight and actually starts thinking).
I also think Sir Alex Ferguson knew that Rooney’s mind was made up. But that’s when Fergie boxed clever. Instead of going on an obvious offensive, giving Wazza the infamous “hairdryer” treatment in public, Fergie acted wounded and bemused, appealing to Rooney’s better nature.
Every parent will recognize the “Son, after all I’ve done for you, what have I done to deserve this?” shtick. Well, I say every parent, but Rooney’s son is only a baby so obviously he won’t have had need for that trick yet. Regardless, it’s a common ruse andit worked on Wazza, introducing a bit of guilt into the equation.
Fergie then played another master stroke, describing the Rooney situation as “ a bagatelle”, which means something trivial, and stressing that the most important thing is not the whims of one player but the club itself. Notably its next game with Stoke City. That surely left Rooney’s obvious sense of self importance deflated, and, by stressing the club above all else, Fergie opened the door for the loyal United fans to weigh in with their damning comments about their former hero’s behavior. And they did, in droves on this website and on sites around the world.
So you see Fergie barely had to lift a finger in heaping more guilt that he could handle on Rooney’s shoulders, and his softly, softly approach, that essentially allowed others and Rooney’s conscience to do the dirty work has paid off. He’s inked a 5 year deal and, what’s more, will be more motivated than ever to perform by way of an apology to the fans and his team-mates for the shenanigans of the last few days.
Fergie you ARE a genius.

Astonishing Madeleine Peyroux


I adore her voice.I'm listening to "Bare Bones" right now.What a fantastic album it is !
Two thumbs up Madeleine Peyroux !

Green Zone

Green Zone Poster
Year : 2010
Directed by : Paul Greengrass
I watched Green Zone with Ardeshir last night. It can be categorized as modern anti-war movies in criticism of  Iraq war .Weapons of mass destruction is sited as the main objective in military operation in middle eastern country .But as the  missions progress several speculations and reports turns out to be deceptive .The movie is based on a solid ground of valid knowledge  about current vulnerable equilibrium of power and prominence of tribal structure. Therefore i 'd rather rank the movie  higher than pure-action type.Green Zone represents an anti-war insight which questions the truthful concern behind the troubled invasion.On the other hand the movie lean too much on Matt Damon's starring . In my opinion the role defined for Damon as a chief warrant officer is a little bit exaggerated .A hunt for truth solely lead by Damon in the context of iraq war chaos is unrealistic.
