A summary of the effectiveness of polyethylene glycol for chronic constipation, fecal disimpaction, and as a bowel preparation are presented in a recent article (JPGN 2013; 57: 134-40).
The article provides information on the biochemistry and mechanism of action along with a good number of references –49.
From the summary:
“PEG is an osmotic laxative used in children in the last few years. It is more effective than lactulose for the treatment of chronic constipation. It is equally effective compared with milk of magnesia and mineral oil for the long-term treatment of constipation but has a much better acceptance rate…It is a safe medication without any significant adverse effects. Because PEG can be mixed in a beverage of the patient’s choice, it has excellent long-term patient acceptance.”

Children with chronic stomach pains are at high risk for anxiety disorders in adolescence and young adulthood, a new study has found (goo.gl/I2UvHP ), suggesting that parents may wish to have their children evaluated at some point for anxiety.
Researchers at Vanderbilt University tracked 332 children with recurring stomachaches that could not be traced to a physical cause — so-called functional abdominal pain — comparing them as they reached young adulthood with 147 children who had never had such stomachaches.
About half the teenagers and young adults who had had functional abdominal pain as children developed an anxiety disorder at some point, compared with 20 percent of the control group, the researchers found. The vulnerability to anxiety persisted into adulthood even if the pain had disappeared, although the risk was highest if the pain continued.
Forty percent of the children with functional abdominal pain went on to experience depression, compared with 16 percent of those who had never had these stomachaches.
The study was published on Monday in the journal Pediatrics.
“What this study shows is a strong connection between functional abdominal pain and anxiety persists into adulthood, and it drives home the point that this isn’t by chance,” said Dr. John V. Campo, chairman of the department of psychiatry at Ohio State University, who was not involved in the new study….
Chronic abdominal pain affects 8 percent to 25 percent of school-age children. The problem can lead to school absences and take a toll on families.
“Somebody might say, ‘Of course they have mental issues or they are emotionally distressed — it’s because of the pain,’ ” said Lynn S. Walker, senior author of the study and director of the division of adolescent health at Monroe Carell Jr. Children’s Hospital at Vanderbilt.
“But we found even if the pain went away, these adolescents and young adults still have anxiety,” Dr. Walker said. “So maybe we need to treat their anxiety.”
The state-of-the-art treatment for functional abdominal pain is rehabilitative, focused on getting patients to participate in daily activities despite their stomachaches. “There’s no question that there are triggers for the pain, but the problem is in the perception of the pain and adaptation to the pain,” said Dr. Samuel Nurko, director of a functional abdominal pain center at Children’s Hospital Boston.
Dr. Nurko compared the pain to a light on a dimmer switch, which psychological techniques can help children control. “You don’t take away the pain,” he said. “You ‘dim’ it to be able to cope better.”
The new study underscores the importance of screening children with the condition for anxiety or depression, the authors said. Anxious children tend to be good children who are concerned about doing their best, Dr. Walker said, and parents may be flummoxed by the suggestion that such a child could be grappling with a mental health issue.

A New Yorker article by Atul Gawande highlights the importance of spending time and talking about good ideas on a person-to-person basis as the best way to help innovations take hold. Specific innovations that are discussed include the introduction of anesthesia, the control of germs/Lister’s theories of sepsis, adoption of oral rehydration solutions, and preventing hypothermia in newborns. The link to the article and a brief video review on the Colbert report:
A recent article provides a useful review for primary sclerosing cholangitis (PSC) (Clin Gastroenterol Hepatol 2013; 11: 898-907).
This blog has previously discussed PSC (links below); however, the above reference is succinct and covers the key issues. A couple of points that I found particularly helpful:
Cancer surveillance:
Diagnosis: 44-56% of patients are asymptomatic at time of diagnosis, picked up due to abnormal serum liver tests or on cross-sectional imaging.
Small-duct PSC: occurs in the setting of features of PSC (histology, biochemistry) without abnormal cholangiogram. This represents 11-17% of PSC patients and is difficult to identify in patients without IBD. Over time, 25% will develop large-duct PSC. Small-duct PSC does not appear to result in increased risk of CCA.
Overlap syndrome with autoimmune hepatitis: patients with typical PSC but with 5- to 10-fold aminotransferase elevations should be suspected of having an overlap syndrome and may benefit from treatments directed at autoimmune hepatitis. Other features often include histology with an interface hepatitis and the presence of auto-antibodies. This situation is more common in children and young adults.
Immunoglobulin G4-Related sclerosing cholangitis: this occurs most commonly in conjunction with autoimmune pancreatitis. Since steroids can be effective, IgG4 levels should “be tested in all patients with suspected PSC, and, if elevated to consider an evaluation for IgG4-related disease.”
Medical management: “to date, there are no medical therapies that have been proven to alter the natural course of PSC.” The discussion notes that standard doses of ursodeoxycholic acid (UDCA) may have protective effects against colorectal cancer in patients with coexisting IBD. Higher doses of UDCA have been associated with a 2-fold risk of increased disease progression. Specific treatments for dominant strictures, pruritus, metabolic bone disease, and malabsorption are discussed. In patients with cholestasis, monitoring fat-soluble vitamins is important.

The following except from the New York Times (nyti.ms/1cvUprv ) by Haider Javed Warraich provides some useful advice when families members ask “What would you do if this were your mother?” In pediatrics, the question is similar: “What would you do if this were your child?”
The patient was an elderly woman, admitted to our unit just a few hours earlier, with a breathing machine keeping her alive. We proceeded with the meeting as we were trained to do. We kept our elbows off the table, maintained eye contact (but not too much) and gave the family an update of where we stood.
A healthy family meeting, we’d been told, involved us speaking for about half the time, with the family speaking for the rest – venting, questioning, grieving and hoping, in no particular order. This meeting, though, was dominated by long periods of silence that unearthed the dull, low-pitched drone in the background.
The son, quiet for most of the meeting, broke the silence and, with a hint of anger and a big dollop of frustration, asked the one question I had dreaded being asked the most: “Doc, give it to me straight. If this were your mother, what would you do?”
While the patient-doctor interaction varies widely across cultures and continents, this question seems to be a universal constant…
From a patient or family member’s perspective, though, this question helps them make sense of the confusion, desolation and powerlessness that so often defines the hospital experience, which usually involves a full-on assault of numbers, jargon and ‘expert’ opinion. They are confronted with difficult choices, like whether they want to go ahead with a particular high-risk procedure or wait for the tincture of time to kick in…
Yet I still find this question hard to answer. See, my mother is the sort of person who spends two hours each day on the treadmill, even during vacations, so that she can eat to her heart’s content. Often described as a “fighter,” any additional moment she can spend with her children or future grandchildren would be worth the extra mile. My father, on the other hand, is someone who avoids getting his blood sugar level tested to evade medications and dreams of spending his last days in the quiet serenity of the village he grew up in. Thus my answer to the question would be very different, as it would be for anyone, depending on which parent you asked me about.
So I have come to believe that the right answer to the question, “If this were your mother, doctor…” is: “Tell me more about your mother.”
This response gives patients’ families the chance to think about their loved ones, about what they would value and what they would consider a good life, what they would think was worth fighting for if they were available to answer the question for themselves….And then, slowly, the family started sharing stories of the woman we had met only a few hours before, unconscious and intubated. She loved being independent, would hate for people to open doors for her or hold her hand as she tried to get up, they told us. She loved the sun, the beach. She loved walking, loved being out and about. She would never, ever want to go to a nursing home…
We then told them that based on a combination of her vital signs and lab values, as well as our clinical judgment, that while we could hope for some progress, it would likely not be enough to allow her any real shot at experiencing life outside a nursing facility again…
They turned to us and asked us to make her comfortable, and to turn off the breathing machine.

In 1991, the World Bank and the World Health Organization launched the Global Burden of Disease Study. A recent article reviews the key findings (NEJM 2013; 369: 448-57).
The goals of the study are to compare the burden of one disease with others; as such, it is “necessary to consider the age at death and life expectancy of persons affected by each disease and to take account of the degree of disability (eg. discomfort, pain, or functional limitations.” A comprehensive measure of disability, disability-adjusted life-years or DALYs, was used for comparisons.
The study examined 291 types of diseases and injuries as well as 67 risk factors in 187 countries, looking at the years 1990, 2005, and 2010.
Findings:
Since 1990, there has been a shift. “In general, communicable, maternal, neonatal, and nutritional conditions decreased in absolute terms.” The main exceptions were HIV and malaria. Noncommunicable diseases, especially diabetes, have been increasing in terms of percentage and absolute numbers.
Another important change has been a relative increase in disability compared with premature death. In addition, of the “top 25 causes of years lived with disability, only COPD, diabetes, road-traffic injury, ischemic heart disease, and diarrhea are also among the tope 25 causes of years of life lost.” “What ails most persons is not necessarily what kills them.”
Bottom-line: While collecting this type of data has many potential limitations, the broad picture it provides should help inform policymakers with priorities for research and intervention. This data also allows the US to benchmark its efforts compared to other countries. For example, according to the authors, currently the US has the best global performance with respect to stroke and the worst with respect to lung cancer and Alzheimer’s disease; however, “data and analyses are lacking to elucidate the drivers of these changes in relative performance.”
A recent study provides some good news for those using thiopurines (6-mercaptopurine and azathioprine) (Gastroenterol 2013; 145: 166-75).
Using the observational cohort enrolled in the French CESAME study (Cancers et Surrisque Associe aux Maladies Inflammatoires Intestinales En France), the authors followed 19,486 patients with IBD. 60.3% had Crohn’s disease, and 30.1% were receiving thiopurine therapy. The study period was 2004-2007. At the start of the study, 2841 patients (14.6%) had long-standing extensive colitis.
Among patients with long-standing extensive colitis, the hazard ratio for colrectal high grade dysplasia and cancer was 0.28 for those who received thiopurine therapy compared with those who never received thiopurine therapy.
Thus, this prospective study showed that while colorectal cancer (CRC) was increased in IBD patients with long-standing colitis, this risk was less among the subset who were treated with thiopurines. Some previous studies have not found a reduction in CRC risk, though they may have been underpowered and biased as these studies came from referral centers.
The authors also cautioned that more than 1/3rd of CRC cases occurred in those without extensive colitis which may necessitate a lower threshold for screening colonoscopy.

As noted in previous blogs (see below for links), ingested magnets represent a significant problem. Two more studies add data to this issue:
The first study relates a retrospective single-hospital experience from 1995-2012 (from Boston). In total, 112 cases of magnet injuries were identified using an initial computer search followed by manual chart review. The mean patient age was 6 years. The incidence rate ratio of 3.44 during the period 2007-2012 indicates a significant uptick in these injuries compared with the prior period. In addition, “office toys” accounted for 18 of 45 injuries during this latter period. Nature of injuries: swallowed magnets accounted for 86% of these injuries with 13 (12%) requiring endoscopic removal and 4 (4%) needing surgical intervention.
The second study analyzed a nationally representative same from the US Consumer Product Safety Commision Database (NEISS) for emergency department (ED) visits involving magnet ingestion in children (< 18 years) from 2002-2011. NEISS sample includes >100 hospitals and 7 children’s hospitals. The authors note that searching NEISS is not always straight-forward as specific product codes need to be entered like toy, kitchen gadget, and others. The findings:
The authors note that one institution has started screening for magnets prior to MRI after a 5 year-old with unrecognized magnet ingestion developed intestinal perforations after undergoing an MRI for torticollis.
Take-home message: Magnets are, in the words of Tom Clancy, a ‘Clear and Present Danger’ as ingestion of more than one magnet creates a high risk of perforation or fistula.
