Nurse!

Conrad Murray now has a chance to improve his success record in treating patients ... because he's back in business.

TMZ has learned the patients this time around will be children with heart problems. Murray has taken a gig with the Trinidad Ministry of Health, where he'll be consulting with local heart surgeons.

Murray won't get rich off the new job -- he's volunteering his services, but it's definitely a foot in the door. His medical license has been revoked in Texas and suspended in California and Nevada.

The government wants Murray to use his U.S. contacts to help hook up the sick kids.

Oscar Pistorius threw up in court today ... several times ... as a pathologist detailed the injuries he found on Reeva Steenkamp's body after she was shot, in gruesome detail.

Pistorius was given a bucket to puke into during the testimony ... and used it quite frequently.

In between vomit sessions, the Olympian was seen rocking back and forth, crying and covering his ears with his hands.

As for the testimony, Professor Gert Saayman detailed the bullet wounds he found on Steenkamp following her death ... saying she was shot on the top of the head, in the right elbow, in the right hip and left hand.

Saayman said the head would have incapacitated Steenkamp immediately. He also said the ammo, Black Talon bullets, are the kind that "expand and mushroom" on impact for maximum damage.

At one point, the judge asked Pistorius' lawyer if he was going to be able to compose himself and stay in the courtroom. Oscar said he wanted to continue ... and was allowed to stay.

The doctor who invented "Tommy John Surgery" ranks up with Jackie Robinson when it comes to people who changed baseball forever ... so says Tommy John himself.

TMZ Sports spoke with the iconic MLB pitcher after the passing of Dr. Frank Jobe -- the man who pioneered the elbow surgery that saved Tommy's pitching career ... and countless others.

The surgery, which Jobe first performed on Tommy in 1974, was revolutionary ... in which a torn tendon in the elbow is replaced with a healthy tendon from somewhere else in the body.

John was the first major athlete to undergo the procedure ... and went from considering retirement to winning 164 GAMES following the surgery.

But Tommy says Dr. Jobe wasn't 100% confident it was going to work before he went under the knife.

"Before the surgery, Frank said to me 'do you have something else to do? I'm not sure this is going to work.' He knew my wife was pregnant."

Fortunately, the whole thing worked out ... now more than 1/3 of active MLB pitchers have undergone the "Tommy John surgery."

John says ... "Three people changed baseball more than anyone: Jackie Robinson, who broke the color barrier. Marvin Miller who changed the players union. And Frank Jobe, who revolutionized the medical side of baseball."

Tommy says he was surprised when he learned of Jobe's passing this week ... explaining, "I sent Frank an email a few weeks ago and I told him 'if I get into the Hall of Fame, I want your butt standing next to me.' He was one of the most important people in my career."

Arnold Schwarzenegger is still being haunted by his political past ... the ex-Gov. is being sued by inmates who accuse him of sentencing them to a fate worse than prison -- a cruel, disfiguring and crippling disease.

According to the lawsuit filed by 22 current and former inmates ... Schwarzenegger and other officials knowingly kept them in a Central Cali prison where they claim Valley Fever killed 30 inmates, and left many more with horrible symptoms.

Valley Fever attacks the body's organs ... victims may suffer skin lesions, limb amputations and brain damage. The disease is spread by spores found in soil -- and the inmates say they were exposed to it.

The inmates are also suing current Gov. Jerry Brown ... claiming he continued Arnold's policy.

They want cash to cover medical care, and pain and suffering -- beyond the typical prison pain and suffering.

A stuntwoman from "iCarly" claims the production ruined her career by recklessly dropping her from high above the ground ... causing gruesome injuries.

Katina Waters claims in a new lawsuit she was hired for a stunt on "iCarly" ... where she would be slowly lowered to the ground while attached to a wire. Instead ... she claims the person operating "the descender machine" dropped her without warning ... and she crashed to the floor.

Waters -- a 40-year old stunt actor who's performed in dozens of TV shows and movies -- says the landing caused severe injuries to her leg, including fractured bones and torn ligaments.

Someone put a spell on Carlton Gebbia -- the Real Housewives of Beverly Hills' resident witch -- passed out at dinner tonight and had to be taken to a hospital by ambulance.

Carlton was having dinner at Mastro's Steakhouse in Bev Hills ... and according to sources in the restaurant she'd been boozing ... HARD.

We're told Carlton was footing the dinner bill for her party of 6 women -- and immediately started the night by slamming tequila shots ... at least 5 of them.

After that, things went downhill quickly and only 20 minutes into the dinner ... Carlton passed out at the table -- and someone called 911 at 9:22PM PT.

Witnesses tell us it appeared Carlton was still unconscious when she was wheeled out of the restaurant on a stretcher and placed in the ambulance.

The girl Jamie Lee Curtis saved from an overdose last week was lifeless and barely moving when the actress called 911 ... and the scary scene was all caught on video.

We broke the story ... Curtis called an ambulance while driving her friend to the hospital last Tuesday -- after the woman suffered a violent reaction to alcohol and Rx meds.

In the video, emergency workers pull her out of the car through the trunk ... and a worried Jamie watches on as they handle the situation.

Sure, George Lopez got bombed and wound up passed out on the floor of a casino -- cause, y'know ... not too many other options when you suck down several dozen shots.

Liquor. It's complicated.

WWE honcho Vince McMahon accidentally dropped a powerbomb of his own during a taping of "Monday Night Raw" ... sharting himself in KHAKI PANTS right before a live segment ... so says Jim Ross.

Ross was dishing on his former boss' "Al Roker" moment during an interview on the "Opie & Anthony" radio show ... saying Vince was trying to jokingly fart in a producer's face ... when his plan backfired, literally.

"It got liquid," Ross said ... "He sharted."

And how did everyone know? Jim says it stank ... plus, the evidence was splattered all over Vince's khaki pants.

As The Rock would say ... Can you SMELLLLLLLLLLLLL what McMahon is cookin'?

LeBron James' awesome black facemask ain't for everyone .... especially white people ... so says caucasian NBA star David Lee.

The Golden State Warriors big man was boarding the team bus outside the Trump International over the weekend when he told us he was a big fan of LeBron's look.

But Lee admitted he won't be getting a black mask of his own anytime soon ... saying, "I'm a white guy. It wouldn't look right."

Chris Kattan is not on a prescription pill-induced downward spiral ... he's just got a bad back.

Kattan blew out of LA Friday before the Oscars hit town ... and chalked up his bizarre behavior on a plane -- and his subsequent DUI arrest last month -- to Rx meds after back surgery.

Kattan doesn't tell us when he underwent surgery ... but assures our photog he's doing just fine.

We also asked about DUI charges filed this week, but he's totally in the dark.

Jennifer Lawrence is two for two at the Oscars -- no, we didn't spoil show for you -- we're talking about the actress almost falling on her face again ... this time on the red carpet.

Ol' clumsy pants hit the press line and as soon as cameras locked in on her ... the "American Hustle" star lost her balance and went down hard.

As you may recall, Lawrence crashed last year during the show while walking on stage to accept her Academy Award.

If history is any indication ... someone's getting photo bombed next.

NFL guru Jay Glazer -- the first guy to interview Richie Incognito about the Dolphins bullying scandal -- tells TMZ Sports ... Richie has some serious psychiatric issues and he's glad he's getting help.

Jay was leaving 1Oak nightclub in Hollywood Friday night, when our guy asked if Richie's decision to seek psychiatric help Thursday night was simply a P.R. move to win some sympathy ... but Jay shot that theory right down.

"Richie's got some issues there ... I'm glad he's getting help."

Chris Brown has been diagnosed with bipolar disorder, severe insomnia and Post Traumatic Stress Disorder ... and that's why he has had such anger issues ... this according to new court docs.

Chris was in court today for a progress hearing in the Rihanna beating case. Documents were filed by the facility where Chris just completed 90 days of anger management therapy. In fact, Chris stayed longer, just completing 95 days.

In the legal docs -- obtained by TMZ -- an official from the rehab facility wrote that ... in addition to his diagnosis ... Chris was self-medicating inappropriately.

The facility writes, "Mr. Brown became aggressive and acted out physically due to his untreated mental health disorder, severe sleep deprivation, inappropriate self-medicating and untreated PTSD." They never explain the cause of the PTSD. The letter also says Chris was diagnosed with Bipolar II.

The letter says Chris is on meds for the bipolar and other conditions.

Chris has learned various relaxation exercises, according to the letter, and he's tested negative for drugs, including weed, during his stay.

Richie Incognito is being held on an involuntary psychiatric hold ... but HE was the one who initially wanted to get help ... TMZ Sports has learned.
