GEORGE BAILEY EFFECT

It’s A Wonderful Life: One psychology study coined the “George Bailey effect,” named for the jolt of happiness that comes from being surprised that a good thing can and did happen to you.

LUCKY PREPARED

He offers a simple example of running out of ink in the middle of a print job. “The lucky person will have got a spare cartridge just in case because they have planned ahead. When the cartridge runs out they’ll say, ‘Oh, aren’t I lucky, I bought one earlier, that’’ fantastic,’ ” Maltby says. “However, the unlucky person won’t have planned ahead, won’t have done the cognitive processes, so when the printer cartridge runs out and they’re left with something to print, they go, ‘Oh, I’m so unlucky.’ ”

UNLUCKY X LOWER EXECUTIVE FN

Psychologist John Maltby of the University of Leicester hypothesized that beliefs in being unlucky are associated with lower executive functioning—the ability to plan, organize, and attend to tasks or goals.

P SHARED BREATH


It was late afternoon in Virginia, humid but not too hot. The Hampton River rippled with a light breeze, lifting skirts and blowing ties. Guests sipped their beer and swayed a little — the way one does when watching a slow dance, unconsciously mimicking the movement of other bodies — as Chris Nalley led his mom on the floor. His bride stood nearby, red-gold curls framing her face, watching her new husband with a smile. Chris looked poised, in control of the dance, as a man looks when a long-awaited moment arrives and he steps confidently into its shape. A moment later his mom stepped away, and he gestured toward another woman standing nearby, a blonde in her 40s.
“Who’s that?” I asked my husband, who grew up with the bride.
“It’s his donor mom,” he whispered back.
Vicky West stepped into Nalley’s arms and laid her ear to his chest. Inside she could hear Nalley’s breath. The warm Virginia air moved through two lungs donated by a boy named Hans, who died of a brain aneurysm at age 20. West’s son’s lungs.
“I was like, ‘Oh my gosh, what if I have a breakdown in the middle of the dance floor?’” West recalls. She had brought her sister and her best friend to the reception to help her prepare for the emotional moment. “I’m never going to dance at my son’s wedding, and he’s my only child. They gave me something that I never thought that I would get.”
West and Nalley didn’t know each other when Hans died. For years after his organs arrived at the University of Virginia, on ice, to be inserted into Nalley’s body, they didn’t even know each others’ names. But over time, they’ve developed a relationship that is both tentative and incredibly tender. They consider each other family, but each of them worries about putting pressure on the other person to have a relationship. West thinks of Nalley as her own child in many ways, but she knows he has a life, a marriage, his own separate identity. Nalley struggles with survivor’s guilt, knowing that Hans died and he is here. He refers to the lungs as not his own, as if they were foreign objects inserted into his body, which medically, in some ways, they are. Both Nalley and West are passionate about organ, tissue, and eye donation and the gift of connection and continuation it provides — even as it accompanies, inevitably, great grief.
* * *
“The science behind how I have these lungs, and they’re not mine, and they’re hooked up like you change a pipe under the sink — you know, switch the plumbing out — is just amazing,” says Nalley. As the recipient of two separate lung transplants, most recently from West’s son, Nalley has a healthy awe for modern medicine.
Complex medical procedures can seem to the layperson almost magical. We can snip out someone’s heart, put it into someone else’s body, and it starts beating. We can graft tissue and replace corneas. We can sustain heartbeats and blood pressure using complex machines, which loop the blood out of the body, oxygenate it, and feed it back in. These procedures come with great risk, but at least they are possible. For most of human history, the things that killed us just killed us. Now, with the help of machines, doctors, and humans who give pieces of their bodies to complete strangers in death, we can live longer, healthier lives. As modern people, we exist not only as ourselves any longer, but as the interconnections between various humans and technologies.
This is true for most people who have faced a medical crisis and relied on a network of humans and machines to save them. In such a crisis, the boundaries of identity become more permeable and the sense of self expands. Organ donation brings this node of connections, this strange, nebulous feeling of trust and gratitude, into sharp focus because of the physicality of the connection: Those who have received a donation literally carry the DNA of the other person inside them. Sometimes recipients also become invested in relationships that nurture, honor, and remember the donor, and they find a relationship with the donor’s family and identity. Communicating can help all sides make sense of a complex, emotionally challenging situation. In some cases, the recipient never learns about the donor and comes to accept these new body parts as their own, creating a new sense of wholeness as they heal.
It wasn’t that long ago that the idea of cutting someone’s lungs out and surgically implanting them in someone else’s body would have been absurd. Just 175 years ago, doctors used ether anesthesia for the first time. The first successful kidney transplant was only 65 years ago. It wasn’t until the 1980s that the first successful lung transplants took place. In 1986, the date of the first successful double-lung transplant, Chris Nalley was 6 years old.
* * *
I was 17 years old when my parents announced that we were going on a 10-day silent Buddhist meditation retreat. Despite initial doubts, I ended up enjoying it: long quiet walks around the UC San Diego campus, tasty vegetarian meals, morning meditations rung in by a bell. I especially remember our teacher. At the time, I thought of him as a brown-robed, slow-talking old man. After almost two decades of meditation practice, I now know him as Thich Nhat Hanh, a renowned Zen teacher and peace activist.
Toward the end of the retreat, he sat onstage in front of a line of candles. Cupping one hand to protect the flame, he lit a candle, then blew out the match. He used the first candle to light a second. He used the second candle to light a third. And so on. Then he gestured to the last candle and asked us whether the flame in this final candle was the same flame that had lit the match.
As modern people, we exist not only as ourselves any longer, but as the interconnections between various humans and technologies.
I didn’t understand that demonstration until many years later, when I became a mom. At one day old, my son was hooked up to a ventilator, unable to breathe on his own, heavily sedated with morphine. The doctors said he had holes in his lungs, and they suspected brain damage as a result of oxygen deprivation during labor. As a newborn, my son was not eligible for a transplant. We could only watch and wait to see if his lungs healed.
Standing over his crib, my hand on his softly moving chest, I understood how the self could transfer into another body and also be separate. This tiny creature had been inside me less than a day ago, and now struggled to breathe on his own. He still felt like a part of my body that had been recently extracted on an operating table. I had a thick, puffy scar across my abdomen where they’d pulled him out, and I could see the dimpled chin he’d inherited from me, the same chin I had inherited from my father, beneath all the plastic tubing.
“We think of our body as our self or belonging to our self. We think of our body as me or mine. But if you look deeply, you see that your body is also the body of your ancestors, of your parents, of your children, and of their children. So it is not a ‘me’; it is not a ‘mine,’” writes Thich Nhat Hanh in Lion’s Roar, a Buddhist magazine. “Your body is full of everything else — limitless non-body elements — except one thing: a separate existence.”
Buddhists call this lack of separateness “no-self.” It’s not a denial of our existence, but the acknowledgment that we exist only in relationship, in community, in continuation. In my family’s experience with the health care system, I saw how fragile our bodies are, how quickly they can come to rely on others for survival. When my son got sick, I stopped seeing myself as an isolated individual, a person who makes individual choices and suffers individual consequences. Instead, I saw the ways in which bodies are made up of both personal characteristics and the myriad influences of their environment, carrying with them the DNA, the traumas, the bacteria, the gifts and generosities of other people. We carry our parents, but also our doctors, nurses, teachers, organ donors: All these people flicker in us, tiny, guttering lights shielded from the wind by cupped hands.

The last thing Nalley remembered, it was January. He’d been arguing with the doctor. He needed an antibiotic for pneumonia, but as a manager for a busy shoe store, he had used up his limited days off and had to get back to work. He remembered getting angry at being detained. He remembered yelling a little.
Now as he looked out the hospital window, unable to move, heart racing, he saw leaves on the trees. It was May.
Nalley panicked. He had been asleep for five months. His heart rate and blood pressure shot up, and the staff surrounded him, trying to calm him down. They gave him something and he slipped back into sleep.
They woke him a few times, until, gradually, he understood what had happened. Admitted to the hospital in January 2005 with pneumonia, Nalley had become angry when the doctor told him he would be there at least a week. “I just wanted to go home and go back to work the next day,” he says. Eventually, he had fallen unconscious from lack of oxygen. He was intubated, given a tracheotomy, and placed in a medically induced coma for months while his lungs fought off the infection.
Nalley had been in the hospital a lot. He was born with cystic fibrosis, a chronic, progressive disease that gradually impairs lung function. The disease typically worsens in late adolescence and early adulthood, just as a person’s identity begins to crystallize. Infections like pneumonia become more common, leading to long-term antibiotic use and complications. While treatments are available, there is no cure.
When he had learned to walk and eat again after months of muscle atrophy, Nalley went home, still dependent on supplemental oxygen. Anytime he went outside, he carried portable oxygen tanks with him. “So much oxygen would flow out of the tank that it would burn your nose,” Nalley recalls.
Running errands became a negotiation of time versus liters. He could carry smaller oxygen tanks, each of which lasted about four hours, so he had to think ahead: If he got caught in traffic and ran out of air, he could get sick from oxygen deprivation. “I felt like an astronaut,” he says.
Being in his early 20s, all he wanted was to go to bars, hang out with friends, and flirt with girls. Instead, for a year and a half, his day-to-day life became a dull routine of television, computers, and forced social interaction. As his lung function declined further, doctors offered Nalley an opportunity: He could get on the list for a lung transplant.
* * *
When a potential organ or tissue donor dies, several teams kick into immediate action. For a case like Nalley’s, there are two surgeries: the donor and the recipient. First, the donor’s lungs are removed, a process that involves stapling shut the major vein and artery that take blood to and from the lungs, as well as closing off the bronchus, the main passage through which air passes. The organs are cut out, treated with blood thinners and preservation solutions, checked to make sure they don’t have too much fluid or any signs of infection, and kept cool.
“You want to be ready to sew the lung very close to the time it arrives,” explains Frederick Tibayan, a surgeon who heads the advanced heart failure and transplant program at Oregon Health and Science University. That’s because “when the lung or lungs have been removed from the donor’s body, it’s no longer being perfused with blood that is giving it nutrients and keeping that organ alive.” So while the lungs make their way to the recipient, possibly from another hospital or city or even state, in haste, another team of surgeons preps the recipient.
It’s a “highly coordinated dance,” says Sarah Kilbourne, an assistant professor of medicine at the University of Virginia who works on Nalley’s care team. A nationwide computer program matches organs by blood type to the highest-priority recipient waiting for a donation. This happened in 2006, and again in 2013, when Kilbourne got a telephone call saying there was a lung available for Nalley. Both times, Nalley got to the hospital as fast as possible. In preparation for a potential procedure, he’d been trying to gain weight, doing physical therapy several times a day on his failing lungs, and keeping himself as healthy as possible for major surgery.
“I was gung-ho, let’s get this thing over with,” Nalley remembers of the first surgery. “In pre-op my parents were crying and I was, like, so ready to have this transplant. I was at the bottom of the barrel of life. Anything would have been better. Half a lung, one lung, a whole lung. Anything.”
Complex medical procedures can seem to the layperson almost magical. We can snip out someone’s heart, put it into someone else’s body, and it starts beating. 
Nalley was having a bilateral transplant, which meant both lungs would be taken out. In this situation, the surgeons either do a clamshell incision, which involves slicing up the sides of the body and across the breastbone, or they simply divide the breastbone and open up the torso. They take out the worse-functioning lung first, again by stapling shut the bronchus and blood vessels and removing the organ, then sewing in the donated organ. “This is obviously stressful for the patient because they’re working on one lung. The heart is having to pump all the blood through one lung and having to work harder,” explains Tibayan. In around 25 percent of cases, the patient has to go on cardiopulmonary bypass, a machine that helps the heart handle the stress. Once the second lung is sewn in, the goal is to get the patient up and moving as fast as possible, to strengthen the heart and get the lungs working on their own.
“I tell people that after the first transplant, that first breath I took was the longest, deepest breath I’d ever taken in my life, and it wasn’t even … it was someone else’s lungs that were doing all the work,” says Nalley. He knew that a stranger’s body had been joined with his, letting him take these deep breaths. Generally, donors’ names and identities are kept anonymous. Nevertheless, the sense of breathing as or with someone else hits home for Nalley. “It messes with your mind, similar to thinking about how small we are in the universe. That the universe is so vast and then you think, there’s this part of me that’s not me … but I’m alive because of it.”
* * *
When Tibayan mentioned to me using a form of cardiopulmonary bypass called extracorporeal membrane oxygenation, or ECMO, in transplant surgery, I remembered what it looked like. The ruby blood in thick tubes. The sound of the nurses banging their fists against the machine to prevent clots. The way the patient is sometimes drugged up to prevent him from moving, so that the canula feeding directly into his carotid will not jostle and detach.
My son was on ECMO for 10 days. He was kept alive effectively as a cyborg, his vitals inextricably linked to the machine that kept him breathing — and to the nurses who monitored the blood as it circulated out of his body, and the doctors who checked for air leaking into his chest cavity. I remember the strange attachment to the machines that were keeping him alive, a simultaneous revulsion and tenderness for the care he received. Beside the high-tech instruments in the room, a small electric candle flickered in the window, near the cot where I or my husband slept each night. I had never imagined that parenthood would begin mostly as a vigil.
“Impermanence means being transformed at every moment. This is reality. And since there is nothing unchanging, how can there be a permanent self, a separate self?” writes Thich Nhat Hanh. “So what permanent thing is there which we can call a self?”
The son I have today exists as the confluence of machines and humans. Ten years earlier, the ECMO technologies and caregiver training wouldn’t have been in place to save him. In 2017, they were. He may not be attached to those devices any longer, but they resonate in him with every breath he takes. Most people who have gone through a major medical event understand that we emerge back into health connected to our caregivers and to the expansive web of lifesaving practices that make up modern medicine. My son is not a machine, but he is alive because of them.

BRAIN X REALITY ENGINE

What we perceive has little relation to reality, argues Professor Donald Hoffman.
Our perceptions — what we see, hear and feel — have little to do with reality, a prominent vision scientist argues.
These perceptions are, in fact, like the screen of our phone or computer, says Professor Donald Hoffman.
What appears on the screen of a phone bears little relation to what is going on inside the machine: the reality of semiconductors and electrons.
In some ways, the internal mechanics of our technology do not matter to us.
What matters is the result: how to send a text message or block a call.
One example of how our mind does not perceive reality is a visual illusion like this one:
The image is flat and does not move, yet most people see a 3D image, parts of which definitely appear to be moving.
(If you do not see any movement, try moving your eye around the image, you should see something then.)
We call the image an ‘illusion’, but what if all of what we see is like this illusion?
Professor Hoffman believes that what we perceive as reality is really only designed to help us survive.
Our brains are tools that allow us to work out what to approach and what to avoid.
If the brain senses a snake, it tells us not to pick it up.
We do not need to see or understand the reality of the snake to survive; we only need to know that we should avoid it.
Our brains are ‘reality’ engines, Professor Hoffman says, continuously manufacturing our experience:
“I’m interested in understanding human conscious experiences and their relationship to the activity of our bodies and brains as we interact within our environment—and that includes the technical challenge of building computer models that mimic it, which is why I’m working on creating a model that explains consciousness.”
In many ways, our perceptions hide the truth of reality from us to help us survive, Professor Hoffman says.
The fundamental nature of reality is, in fact, consciousness, Professor Hoffman believes.
Although, of course, that is rather difficult to prove.
The ideas are discussed in Professor Donald Hoffman’s book “The Case Against Reality“.

The story says that a little girl offered Gautama a bowl of rice. Once he accepted it and ate, he realized that the extreme behavior he was living out did not point towards the direction of inner liberation. He learned that living under harsh physical conditions wasn’t the answer to the spiritual release he set out for. After this realization, Gautama urged others to follow a path of balance instead of the one he painted out through extremities – he named this path of life the Middle Way. 

DWM STATIN X DM2

Statins Linked to Higher Diabetes Risk


Statin use is associated with an increased risk of new-onset diabetes (NOD), according to the results of a recent study.1
While statins are one of the most widely prescribed medications worldwide, concerns about the drugs’ associations with dysglycemia and NOD still remain.


To explore this association further, researchers examined data from a cohort reflecting real-world physician prescribing patterns (including 7064 individuals with indications for statin use).
Overall, a higher prevalence of elevated HbA1c was observed among incident users of statins without diabetes, and further, statin users had a higher risk of developing NOD (average hazard ratio [AHR] 2.20). Individuals who took statins for 2 years or longer had the greatest risk of developing NOD (AHR 3.33).
“The fact that increased duration of statin use was associated with an increased risk of diabetes – something we call a dose-dependent relationship – makes us think that this is likely a causal relationship,” said lead author of the study Victoria Zigmont, who is a graduate student at The Ohio State University.2
“That said, statins are very effective in preventing heart attacks and strokes. I would never recommend that people stop taking the statin they’ve been prescribed based on this study, but it should open up further discussions about diabetes prevention and patient and provider awareness of the issue,” she concluded.

A Newborn With Abdominal Pain

Riham Alwan,

Abstract

A previously healthy 3-week-old boy presented with 5 hours of marked fussiness, abdominal distention, and poor feeding. He was afebrile and well perfused. His examination was remarkable for localized abdominal tenderness and distention. He was referred to the emergency department in which an abdominal radiograph revealed gaseous distention of the bowel with a paucity of gas in the pelvis. Complete blood cell count and urinalysis were unremarkable. His ongoing fussiness and abnormal physical examination prompted consultation with surgery and radiology. Our combined efforts ultimately established an unexpected diagnosis.

  • Case History

    Dr Riham Alwan (Pediatric Emergency Medicine Fellow) and Dr Meredith Drake (Pediatric Resident):

    A 3-week-old boy was referred to the emergency department (ED) from his pediatrician’s office with irritability, poor feeding, abdominal tenderness, and distention. In the pediatrician’s office he was irritable, and he was noted to have a somewhat rigid, distended, and slightly discolored abdomen in addition to bilateral eye drainage. He was born at 37 weeks and 6 days to a gravida 2 para 2 mother via normal spontaneous vaginal delivery. Cefazolin was administered to his mother predelivery for positive group B Streptococcusstatus. Prenatal, birth, and postnatal course was otherwise unremarkable. Starting at ∼2:30 am on the day of presentation, his parents reported that he had been fussy, with a cry described as “painful.” He had been more difficult to console and had been refusing feeds by either breast or bottle. He had 1 episode of forceful emesis 2 days before presentation, and otherwise he had minimal spit up, which was always nonbilious and nonbloody, after feeds. His stools had been soft and seedy, without blood or mucous. He passed meconium within the first 24 hours of life. He had been gaining weight appropriately.
    On examination in the ED, he was alert but uncomfortable. His temperature was 37.5°C, pulse was 184 beats per minute, respiratory rate was 40 breaths per minute, and blood pressure was 107/68 mm Hg. The examination of the heart and lungs was normal. He had normal pulses and a capillary refill time of 3 seconds. There were no skin rashes. He had good tone. He had mucous drainage from both eyes without conjunctival injection. His abdomen had positive bowel sounds but was moderately distended with diffuse tenderness after palpation. There was no obvious discoloration of the abdomen. There were no masses or organomegaly. An examination of the genitalia revealed bilaterally descended testes with a normal circumcised penis. The perianal area was normal.

    Dr Matheny, as the physician that initially saw this patient in clinic, please tell us about his initial presentation and examination. What was included in your differential diagnosis? Why did you decide to send him to the emergency department?

    Dr Cali Matheny (General Pediatrician):

    Several of this infant’s presenting signs differentiated him from other infants who have fussiness and poor feeding. His symptoms had an abrupt onset. He was irritable and difficult to console. His abdomen was somewhat rigid, slightly distended, and had a mild violaceous hue. I divided my initial differential diagnosis into obstructive and infectious processes, and I believed an obstructive process was more likely given his feeding refusal and the marked decrease in his usual stooling pattern. I was concerned for malrotation with volvulus, intussusception, necrotizing enterocolitis (NEC) and short-segment Hirschsprung disease. I believed that constipation was unlikely given that he was exclusively breastfed. Potential infectious processes included serious bacterial infection (eg, a urinary tract infection). His abdominal examination also made me concerned for NEC. Given this differential, I referred him to the emergency department for further evaluation and treatment including radiographic studies that were not available in my office.

    Drs Alwan and Drake:

    Dr Sobolewski, as a pediatric emergency medicine attending, please share your thoughts about this patient's initial differential diagnosis given the chief complaint and presenting symptoms of fussiness, abdominal pain, and distention? What would be the initial steps in the diagnosis process?

    Dr Brad Sobolewski (Pediatric Emergency Medicine):

    My initial differential diagnosis aligned with Dr Matheny’s and included bowel obstruction (small bowel or distal [eg, Hirschsprung disease]), malrotation with volvulus, neonatal sepsis, NEC, urinary tract infection, constipation, hypertrophic pyloric stenosis, infantile colic, gastroesophageal reflux, nonaccidental trauma, and gastroenteritis. Given that he was consolable, afebrile, and his fussiness seemed to localize to the abdomen, we felt that eschewing the traditional sepsis workup and focusing on the abdomen first was prudent. The initial evaluation therefore began with an abdominal radiograph, which can demonstrate signs of bowel obstruction.
    His abdominal radiograph showed diffuse gaseous distention of the bowel with a paucity of gas in the pelvis (Fig 1).
    FIGURE 1
    Abdominal plain radiographs showing mild nonspecific gaseous distension without pneumoperitoneum.

    Drs Alwan and Drake:

    Dr Emery, as the radiologist who read this abdominal film, what do these findings suggest to you? What diseases can present with these imaging findings in a neonate? Are there other images that may be helpful to obtain initially?

    Dr Kathleen Emery (Pediatric Radiology):

    The findings in this patient’s abdominal radiograph are highly nonspecific. Lack of gas in the pelvis could indicate a distal obstruction or the dependent position of the rectosigmoid. Supine and decubitus are the 2 most useful views to obtain initially. I do not recommend prone views unless there is significant clinical concern for distal obstruction. In that case, then I would recommend placing the neonate on his abdomen for few minutes and evaluating with a prone view for persistent paucity of gas.
    Given the history, this patient could be suffering from early NEC, intussusception, malrotation with volvulus, Hirschsprung's disease, or more commonly, gastroenteritis. If the patient had bilious emesis, I would have suggested an upper gastrointestinal study. Ultimately the history was as nonspecific as the abdominal radiograph.

    Drs Alwan and Drake:

    After reviewing the radiograph we performed a rectal examination, as this radiograph finding could suggest Hirschsprung's. After the insertion of a finger into the rectum the patient expelled copious watery green stool. His fussiness was only relieved temporarily, and he continued to refuse oral intake. Because the rectal examination was concerning for distal obstruction, namely Hirschprung disease, surgery was consulted.

    Drs Shaaban and Gurria Juarez, what findings on initial history and physical examination concern you? What other historical elements are more consistent with Hirschsprung disease and other causes of bowel obstruction in neonates? What specifically in this patient made you question the possible diagnosis of Hirschsprung disease? After evaluating the patient, what was your plan?

    Dr Aimen Shaaban (Pediatric Surgery Attending) and Dr Juan Gurria Juarez (Pediatric Surgery Fellow):

    On initial evaluation in the ED, this patient was clinically stable but irritable. He had a distended but soft, mildly tender abdomen with normoactive bowel sounds. Rectal stimulation was performed with a feeding catheter with immediate return of gas and stool. The history of present illness guided our discussion with the parents toward the possibility of gastroenteritis. We felt that Hirschsprung disease was less likely because he had been healthy and asymptomatic during his initial weeks of life, with a history of passing meconium within the first day of life and having no difficulties stooling. His acute deterioration in health therefore lessened concerns for Hirschsprung disease. The spectrum of Hirschsprung disease encompasses different clinical presentations that can vary from mild constipation to fulminant toxic enterocolitis.1 It commonly presents with failure to pass meconium within the first 24 hours of life and progresses to repeated episodes of constipation.2 In cases that progress to enterocolitis, infants typically develop tense abdominal distention over several hours and have profuse vomiting along with large amounts of foul smelling gas and stool.1,2 Although our patient exhibited abdominal distention, the rest of his clinical picture and history did not fit with the diagnosis. Radiographic findings in our patient were rather nonspecific, and along with his physical examination, the decision was made to treat him nonoperatively. Should his symptoms persist despite medical management, we would then evaluate for Hirschsprung disease.
    The differential diagnosis of bowel obstruction in neonates is broad and diverse depending on the age of the patient. It involves the anatomy from mouth to anus, including esophageal webs, atresia, pyloric stenosis, duodenal web and/or duodenal atresia, annular pancreas, malrotation, jejunoileal atresia, duplications, meconium ileus, microcolon, constipation, Hirschsprung disease, left colon syndrome, atresia, and imperforate anus, among others.

    After discussing the patient with our surgical colleagues, the patient’s mom attempted to breastfeed the patient. He would latch onto the breast for only a few seconds and then pull away. He similarly refused the bottle. At this point, we ordered a complete blood cell count (CBC) and blood culture, catheter urinalysis and urine culture, a basic metabolic panel and a 20 mL/kg normal saline bolus. If the results of the CBC were worrisome, we discussed the pursuit of a lumbar puncture to evaluate for meningitis.
    Ultimately, the results of the CBC, electrolytes, and urinalysis were unremarkable. This left us in a bit of a diagnostic quandary, and we were prepared to admit to general pediatrics.

    Dr Sobolewski:

    What unsettled me was that although the patient fell asleep after the laboratories had been obtained, his abdominal examination continued to be impressive for localized tenderness to the lower abdomen on repeat examination 2 hours after arrival. In fact, I felt that he had outright peritonitis with involuntary guarding and that his acute abdomen would best be evaluated by obtaining an ultrasound.

    Drs Shaaban and Gurria Juarez, what can you tell us about the term infant with peritonitis? What does it suggest in terms of the differential diagnosis and how do you best evaluate it?

    Drs Shaaban and Gurria Juarez:

    The cause of peritonitis in this population is often because of an acute obstruction or perforation as a complication of NEC or intussusception. NEC typically affects preterm infants and presents with abdominal distention and vomiting. As their abdominal distention worsens they may develop occult positive or grossly bloody stools. The abdominal wall may appear erythematous. Abdominal radiographs are used to make the diagnosis and reveal pneumatosis intestinalis or intramural gas.1 Although the initial examination by the primary medical doctor included abdomen discoloration and distention, our patient was born almost to term, had nonbloody stools, and did not have any of the findings on radiograph that are consistent with NEC.
    The evaluation usually begins with blood gas, CBC with differential, C-reactive protein and/or erythrocyte sedimentation rate, lactate level, electrolytes, and blood cultures as well as adjuncts to physical examination such as plain radiographs and ultrasound.3However, an urgent surgical exploration should be considered early in the evaluation of an infant with peritonitis because catastrophic diseases such as midgut volvulus are best diagnosed in the operating room during laparotomy such that the time interval to treatment is minimized. Unfortunately, this requires acting based on a limited amount of data. Waiting for laboratories could have delayed further care and would not have been diagnostic. The lack of bilious emesis in this case diminished the likelihood of midgut volvulus and the more indolent presentation provided support for a limited workup. Fortunately, we were able to obtain an ultrasound quickly, and ultrasound results made the additional laboratory tests unnecessary.

    Dr Sobolewski:

    Dr Emery, is there anything unique about reading an ultrasound inthe newborn? What are some of the limitations of ultrasound in this age group? Why is it a better choice than computed tomography scan?

    Dr Emery:

    Appropriately, you picked up the phone and called me saying, “There is something funny about this kid. He has abdominal tenderness of some etiology.” This speaks volumes to me. If you are worried, communicate your concerns directly to the radiologist. Infants can have significant amounts of bowel gas that can limit the utility of the ultrasound. Their anatomy is small, but usually the ultrasound is an excellent adjunct to the physical examination, if the abdominal radiograph has been unrevealing.
    After speaking to the clinical team, my differential diagnosis still included NEC and intussusception. I have definitely seen both in term infants. Gastroenteritis is common. Anatomic abnormalities such as the malrotation spectrum can also present this way. I think in an infant that young without fat planes that a commuted tomography scan of the abdomen without oral contrast is significantly limited. The ultrasound is a better imaging modality. There is some literature to suggest ultrasound can be useful in detecting pneumoperitoneum, but many radiologists still recommend initial abdominal radiographs for the evaluation of NEC.4 According to Schwartz et al,3 in an infant with signs of abdominal sepsis, the next step after obtaining an abdominal radiograph that is negative for signs of NEC is to obtain an ultrasound of the intestines.5
    On ultrasound, the appendix is usually found after first localizing the cecum. This case was difficult because the appendix was nestled in the right upper quadrant near the inferior edge of the liver, adjacent to the lower pole of the kidney (Fig 2). One of the advantages to ultrasound is the dynamic element during imaging, which improves its utility in an age group that is otherwise unreliable on physical examination.3 This child, for example, cried immediately with attempts to compress his appendix. The ultrasound revealed an appendix that was enlarged and fluid filled. There appeared to be air within the appendiceal wall and impending perforation was an acute concern (Fig 2). In my 27 years, I have never seen a case like this. I see signs of ischemia or localized NEC far more often. Air in the appendiceal wall is extremely rare.

    Drs Alwan, Drake and Sobolewski:

    Because the ultrasound was diagnostic for acute appendicitis, we asked surgery to urgently re-evaluate the patient.

    Discussion

    Final Diagnosis: Acute Appendicitis

    Dr Matheny:

    I think that the important message from this case is that parental calls regarding fussy infants <2 to 3 months of age should be taken seriously. Young infants with fussiness should generally be seen the same day. If the office is closed, these patients should be referred to an ED as opposed to an urgent care. Although the majority of these infants will have common diagnoses, such as developmentally typical crying or colic, some will have more serious illnesses, such as urinary tract infections. Freedman et al6 reviewed 237 afebrile infants <1 year of age who presented to a pediatric ED with crying or fussiness, and they found that ∼5% had a serious illness. If the infant is ill, and especially if they have an acute abdomen, they should be promptly referred to an ED whether diagnostic testing such as radiographs and urinalysis are available in the office.

    Drs Alwan, Drake and Sobolewski:

    Drs Shabaan and Gurria Juarez, how rare is appendicitis in the newborn? How does its presentation differ from that of an older child? What concerns do you have operating on a neonate with this diagnosis? Did you experience any unforseen challenges intraoperatively? During the operation, were the ultrasound findings consistent with the intraoperative findings? How was this like NEC or other intraabdominal calamities in the newborn period?

    Drs Shaaban and Gurria Juarez:

    Appendicitis in infancy is extremely rare but can occur at any age even in premature infants.79 Hence, the wisdom of the surgical dictum, “appendicitis should never be lower than number 3 on the list of differential diagnoses for an acute abdomen.” Clinical findings of appendicitis in the newborn are nonspecific and universally reflect peritonitis from perforation. A high index of suspicion is unlikely given the rarity of this disease, but a surgical bias toward intervention in the infant with a clinical examination suggesting peritonitis provides a critical safety net to prevent missing such a rare diagnosis.
    Given the overwhelming concern for a surgically-relevant intraabdominal pathology, the decision to perform a diagnostic laparoscopy was straightforward. In these cases, converting to an open laparotomy is frequently necessary for both diagnostic and therapeutic considerations.7 The technical approach to appendectomy in a newborn is similar to older children except that the smaller size precludes the use of surgical staplers.
    In our patient, the appendix was visualized through an umbilical laparoscopic port to be located in the right upper quadrant. Fortunately, the length of the appendix was free from attachment to the retroperitoneum making it amenable to externalization via the incision for the second laparoscopic port placed in the right upper quadrant (Fig 3). After externalization, the appendectomy was easily completed by using conventional techniques. In general, the ultrasound accurately predicted the intraoperative findings. However, we found also signs of perforation with purulent fluid throughout the entire abdominal cavity. Thus, copious lavage of the peritoneal cavity was performed before closure. There were no other relevant findings during the exploration.

    Drs Alwan and Drake:

    In reviewing the literature, childhood appendicitis is well described, but neonatal appendicitis is much rarer, with an incidence of 0.04% to 0.2%.35,912 There have been ∼50 cases reported in the past 30 years, most commonly involving premature boys.7,9,11 Perhaps given the insidious onset of this disease and the difficulty of the neonatal examination, the mortality rate has been reported as 20% to 25%.1,3,710 Some speculate that the broadness of the appendix, or its conical shape, combined with the lack of fecaliths in neonates contributes to the rarity of this diagnosis.7,9,1214 Anatomically, the neonate’s appendiceal wall is thinner and perhaps more easily perforated.7,9,15,16 The high morbidity and mortality rate could be attributed to faster progression to perforation, peritonitis, and subsequently septic shock.3 It is important to evaluate each infant on the basis of their unique presentation, and keep neonatal appendicitis on the differential for abdominal distension and feeding difficulty. Of note, Hirschsprung disease and NEC should always be considered when contemplating neonatal appendicitis. Schwartz et al3 present a proposed visual algorithm for neonates with abdominal sepsis as a useful aid.

    Dr Szabo, is your analysis of the appendiceal specimen consistent with the diagnosis or could this be a rare form of localized NEC? Did the histology differ from appendicitis in older children?

    Dr Sara Szabo (Pathology):

    It is not entirely classic for acute appendicitis, but here is what I can tell you based purely on histology. It is diagnostic of an advanced case of appendicitis. It did not appear to be consistent with more extensive bowel disease as seen in NEC. The pathology report reinforces the intraoperative findings consistent with acute gangrenous appendicitis. Sections of the appendix showed extensive and near complete effacement with destruction of the mucosa and muscularis propria by an active chronic inflammatory infiltrate containing neutrophils with lymphocytes, rare plasma cells, and eosinophils (Fig 4). It is essentially obliterated by what appears to be ischemic coagulative necrosis. There was no fibrinopurulent serositis, which would have developed had the inflammation resulted from an adjacent intraabdominal process, such as an abscess. If this child were younger, you could insinuate that meconium obstructed the lumen, not unlike how a fecalith would obstruct the lumen in an older child. However, his gut appears to be colonized, and the lumen was only slightly dilated. Although obstruction secondary to a Ladd’s band, gut malrotation, or incarceration from a hernia had entered the differential, these etiologies have been excluded based on the surgeon’s intraoperative findings.

The mucosa is entirely devitalized (green arrow), with bacterial colonies growing on sloughed luminal debris (asterisk). The submucosa is largely ischemic, with vascular remnants (red arrow). A heavy active inflammatory infiltrate (blue arrows) has overrun the entire muscular wall and subserosa, with remnant ischemic and reactive smooth muscle fibers.

    Drs Alwan, Drake and Sobolewski:

    Drs Shabaan and Gurria Juarez, was his postoperative course prolonged or complicated? How is the neonatal post-op course different from older children?

    Drs Shaaban and Gurria Juarez:

    The major differences that exist between infants and older children or adults relate to the well-documented higher rate of perforation and sepsis.7 The infant or toddler is often perforated (or microperforated or gangrenous) at the time of presentation.5,7,9 This is because of a delay in diagnosis and treatments as well as the fact that the appendiceal wall is thinner in neonates and they have a relatively indistensible cecum. As a consequence, the postoperative course is that of a complicated appendicitis. Additionally, the infant tends not to form a loculated or contained abscess but more often has a free perforation with overt sepsis. The omentum is almost nonexistent thus the contamination will disperse faster. This explains the higher rates of peritonitis and mortality in neonates compared with older children and adults. Although the patient had signs of perforation in the operating room, he had an uneventful postoperative course. He achieved full feeds by post-op day 2 and was discharged from the hospital on post-op day 3. He was found to have a small incisional seroma during his follow-up clinic visit, which resolved with time.

    Dr Matheny, how is the patient doing now?

    Dr Matheny:

    He developed diaper dermatitis shortly after discharge, which was likely secondary to diarrhea from Augmentin use. He has had multiple well child visits since that time and has continued to thrive developmentally and have normal growth, and he has had no issues after surgery.

    Conclusions

    The initial evaluation of the fussy neonate is uniquely challenging. An appropriately thorough history and careful physical examination guides development of the differential diagnosis. In newborns with anorexia and localized abdominal tenderness consider an initial radiograph followed by ultrasound. Appendicitis should always be considered despite its relative rarity. Ultimately, our patient was correctly diagnosed with acute appendicitis and subsequently recovered because of the high index of suspicion. Communication and collaboration among physicians, surgeons, radiologists, and pathologists allowed for an accurate and timely diagnosis.
