Hospitalists a part of multifaceted approach to the crisis

 

The United States is in the midst of a public health crisis. Every day, 91 Americans die from opioid overdoses.1 Opioid addiction has a tremendous negative effect on parents and children by destroying lives and breaking up families. When used appropriately, these drugs, such as morphine, hydrocodone, oxycodone, and fentanyl, provide much needed pain relief to patients, especially after a surgical procedure or during treatment for cancer. Unfortunately, opioids also have qualities that make them addictive and prone to overuse and abuse.

Heroin and other opioid drugs are affecting social, health, and economic welfare in communities throughout the United States. Opioid addiction does not discriminate among occupations, socioeconomic statuses, or ethnicities. Once addicted, users find it difficult to fight and overcome the habit. In this context, hospitalists who develop and use opioid policies and tactics are better equipped to deal with the increasing prevalence of opioid addiction and overdoses seen in the medical center environment.

Overview of opioid addiction

Opioids are more prevalent and easily available today in part because of the intense marketing campaigns by pharmaceutical companies. In fact, according to the 2014 National Survey on Drug Use and Health, almost 2 million Americans were dependent on or abused prescription opioids.2 Opioids create artificial endorphins in the brain, amplifying positive feelings and euphoria. Once they become dependent, patients feel sick and become depressed when they aren’t using narcotics. They experience uncontrollable cravings, relieved only by increasing opioid use. Personal relationships and finances are severely affected because patients will do whatever they can to acquire more opioids. Some resort to doctor shopping to obtain more opioids, while others will engage in drug trafficking to purchase and sell narcotics. Most new heroin users report that they started with nonmedical use of opioid pain relievers.3

Unfortunately, in 2015, there were more than 20,000 prescription opioid overdose deaths and almost 13,000 overdose deaths related to heroin.4 In addition to addiction and death, overuse of narcotics can cause many medical issues, including dizziness, constipation, depression, and immune dysfunction.

As with any addiction, there are many problems related to opiate withdrawal. Some of these include anxiety, rhinorrhea, lacrimation, piloerection, mydriasis, nausea, vomiting, abdominal pain, diarrhea, tachycardia, and hypertension. Methadone, buprenorphine, and extended-release naltrexone typically are used to help alleviate cravings and the symptoms of withdrawal. With more than 1,000 patients treated daily by emergency departments for misuse of prescription opioids, it’s imperative for the medical community to address this health care crisis.5
 

Impact on first responders and hospitalists

The impact of this epidemic on the medical community is dramatic. Emergency system resources, already on overload, are further taxed and drained by the increased 911 calls for overdose incidents. This means that instead of responding to heart attacks, strokes, or other emergencies, first responders are spending time stabilizing overdose patients and taking them to hospitals. This resource drain spreads to emergency rooms and hospitals as they treat these patients. Eventually, the epidemic results in higher insurance costs to cover the impact on medical resources.

Strategies for hospitalists

A multifaceted approach is required to combat this crisis, and hospitalists are one component of that solution. Here are strategies hospitalists can employ to combat the growing use and abuse of narcotics:

  • Screen for high-risk conditions. Before prescribing opioids, screen patients for conditions that may be exacerbated by opioid use, including sleep apnea, obesity COPD, and heart failure, as well as whether they are using medications that cause sedation and respiratory depression.
  • Develop and follow pain management clinical pathway protocols. For example, start with nonopioid analgesics, such as acetaminophen, ibuprofen, and naproxen, for patients with mild pain. If the patient is in moderate pain, or if the mild pain was unrelieved by the first type of medicine, continue with opioid analgesics including codeine, oxycodone, hydrocodone, or morphine. Finally, if the patient is experiencing severe pain, or if the mild to moderate pain was unrelieved by previous medications, prescribe higher doses of morphine, fentanyl, or hydromorphone or use a patient-controlled analgesia delivery of an intravenous opioid.
  • Discuss other treatment options. Instead of prescribing narcotics, assess whether other treatment options are viable. These include physical and occupational therapy, steroid shots, massage, local nerve blocks, and muscle relaxers.
  • Evaluate the reason(s) for current use of prescribed narcotics. It’s crucial to determine why patients are using opioids. The medical condition for which they were prescribed these medications may have resolved. If patients are using opioids without a medically indicated reason, offer alternative medications, such as methadone or naltrexone, and provide education to help them slowly taper off the drugs. Do not cease opioid use altogether unless the use is contraindicated because of other medical conditions or unstable vital signs (for example, low blood pressure).
  • Train nurses on opioid use and addiction. Educate nurses about opioid addiction risk factors and symptoms of addiction. Instruct them on managing the Ramsay Sedation Scale and using an opioid sedation scale with patients receiving IV narcotics.
  • Educate families on opioid use and addiction. Counsel patients and their families on the long-term effects of opioid use and about the warning signs of addiction. Teach them about alternatives to narcotics.
  • Offer referrals to specialized clinics. Work with social workers, case managers, and local mental health professionals to refer patients to behavioral counseling, patient and family support groups, and monitored detoxification clinics qualified to treat opioid addiction.
 

 

Socioeconomic impact

The effects of the opioid epidemic are felt in all areas of the United States, especially in the health care industry. Emergency department visits are mounting while billions of dollars are spent on medical care for those addicted to opioids. Additionally, the socioeconomic effects of this crisis contribute to increasing depression, anxiety, missed days of work or school, unemployment, drop-out rates, and loss of productivity among those addicted to opioids. Also, the epidemic is adversely affecting families, leading to increased divorce rates, single parent families, and child abuse and neglect. By creating strategies and protocols for medical staff, patients, and families affected by opioid use, addiction, or overdose, hospitalists can have a positive influence on patients’ lives and ultimately the opioid epidemic.

Suicide rate highest in rural areas

Article Type

Fri, 01/18/2019 - 17:07

 

The suicide rate in the United States rose over 19% from 2001 to 2015, with an increasing gap separating rural areas from those with large urban populations, according to the Centers for Disease Control and Prevention.

Suicide rates in nonmetropolitan/rural counties for those aged 10 years and older have been consistently higher, and increased more, than those in large metropolitan counties, the CDC said.

The rate in nonmetro/rural counties rose from 15.5 per 100,000 population in 2001-2003 to 19.7 per 100,000 in 2013-2015, an increase of 27%. Medium/small metro counties had a similar 25% jump – the suicide rate climbed from 13.4 per 100,000 in 2001-2003 to 16.8 in 2013-2015. But counties with large metro populations saw a smaller 14% increase, with the rate rising from 11.2 to 12.7 over that time period, the CDC investigators reported (MMWR Surveill Summ. 2017 Oct 6;66[18]:1-16).

The trends for the two lower urbanization levels had similar patterns: increases from 2001 onward became significant accelerations in 2007 (nonmetro/rural) and 2008 (medium/small metro). Large metro counties, however, took a different path that involved significant decreases from 2001 to 2005, significant increases from 2005 to 2010, and then smaller increases after 2010 that were not significant, based on data from the National Vital Statistics System’s mortality data files.

The analysis of the 544,115 suicides committed during 2001-2015 used 3-year averages “to reduce the variability of a small number of observations in a particular period,” the investigators noted.

A Cardiac Tumor Traced to Merkel Cell Carcinoma

Article Type
Changed
Tue, 08/21/2018 - 14:38
Clinicians report a unique patient case in which uncommon cardiac symptoms raised the suspicion and challenges of treating a rare cancer.

A patient with Merkel cell carcinoma (MCC) came to Sir Charles Gairdner Hospital in Perth, Australia, after 2 weeks of dyspnea. He was diagnosed with cardiac tamponade and received urgent pericardiocentesis. An echocardiogram and computer tomography scan showed a large infiltrating mass in the heart. Immunohistochemistry of the pericardial fluid revealed MCC. The MCC had metastasized to his heart—the tenth such reported case, and the second case reported of MCC causing cardiac tamponade.

The clinicians report on several “important illustrative aspects” that appeared while they were unraveling the clues to the patient’s condition. One aspect was the challenge of the histopathologic diagnosis itself. The majority of patients with MCC present with localized disease, they note. Only 4% of patients have distant metastases, usually to lymph nodes, lung, central nervous system, and bone. MCC metastases to the heart are extremely rare. Most commonly, a cancer that spreads to the heart has started in the lungs, esophagus, or breast, or has begun as lymphoma, melanoma, or leukemia.  

However, it’s “exponentially more likely,” the clinicians say, for a cardiac tumor to be a metastasis than a primary cardiac tumor, and it is uncommon for the heart to be the only site of metastatic disease from a noncardiac malignancy. Thus, the patient represented a unique case: apart from an internal mammary lymph node, the heart was the only site of distant metastatic spread.  

This patient’s case highlights the importance of early and accurate diagnosis of MCC with aggressive surgical treatment for localized disease, the clinicians say. New cardiac symptoms in the setting of malignancy should raise suspicion of cardiac metastasis.

Only 4% of patients have distant metastases, usually to lymph nodes, lung, central nervous system, and bone. MCC metastases to the heart are extremely rare. Most commonly, a cancer that spreads to the heart has started in the lungs, esophagus, or breast, or has begun as lymphoma, melanoma, or leukemia.  

However, it’s “exponentially more likely,” the clinicians say, for a cardiac tumor to be a metastasis than a primary cardiac tumor, and it is uncommon for the heart to be the only site of metastatic disease from a noncardiac malignancy. Thus, the patient represented a unique case: apart from an internal mammary lymph node, the heart was the only site of distant metastatic spread.  

This patient’s case highlights the importance of early and accurate diagnosis of MCC with aggressive surgical treatment for localized disease, the clinicians say. New cardiac symptoms in the setting of malignancy should raise suspicion of cardiac metastasis.

High symptom burden in advanced cancer patients

New research indicates that hospitalized patients with advanced cancer have a high burden of physical and psychological symptoms, and this burden is linked to longer hospital stays and a greater risk for unplanned hospital readmissions and death.

Researchers said these findings highlight the need to develop and test interventions to lessen patients’ symptoms.

Ryan Nipp, MD, of Massachusetts General Hospital in Boston, and his colleagues reported the findings in Cancer.

The researchers noted that patients with advanced cancer often experience frequent and prolonged hospitalizations for reasons that have not been fully explored.

To investigate, the team collected information from 1036 patients with advanced cancer as they were being admitted for an unplanned hospitalization.

The Edmonton Symptom Assessment System (ESAS) was used to assess patients’ physical symptoms, and the Patient Health Questionnaire 4 (PHQ-4) was used to assess their psychological symptoms.

The researchers examined the relationship between patients’ symptom burden and the duration of their hospital stay, risk of readmission, and death.

Many patients reported moderate or severe fatigue (86.7%), poor well-being (74.2%), drowsiness (71.7%), pain (67.7%), and lack of appetite (67.3%). Nearly 30% of patients had clinically significant symptoms of depression (28.8%) and anxiety (28.0%).

The patients’ mean hospital stay was 6.3 days, the readmission rate within 90 days of discharge was 43.1%, and the 90-day mortality rate was 41.6%.

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P=0.040), and depression symptoms (P=0.017) were significantly associated with longer hospital stays, but anxiety symptoms were not (P=0.190).

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P=0.072), and anxiety symptoms (P=0.045) were significantly associated with a higher likelihood of readmission within 90 days, but depression symptoms were not (P=0.219).

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P<0.001), depression symptoms (P<0.001), and anxiety symptoms (P=0.012) were all significantly associated with a higher likelihood of death or readmission within 90 days.

“We demonstrated that many hospitalized patients with advanced cancer experience an immense physical and psychological symptom burden,” Dr Nipp said.

“Interventions to identify and treat symptomatic patients hold great potential for improving patients’ experience with their illness, enhancing their quality of life, and reducing their healthcare utilization.”

GRANADA, SPAIN—A monoclonal antibody can resolve co-existing hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA) and graft-versus-host disease (GVHD), according to a case study.

The antibody is OMS721, and it targets MASP-2, a pro-inflammatory protein target involved in activation of the complement system.

The case of OMS721 ameliorating HSCT-TMA and GVHD was presented at the European Society for Blood and Marrow Transplantation Crash Course on Diagnosis and Treatment of Noninfectious Complications after HCT.

The patient was a participant in an ongoing phase 2 trial of thrombotic microangiopathies, including HSCT-TMA. The trial is sponsored by Omeros Corporation, the company developing OMS721.

The patient was an adult male with post-transplant TMA persisting at least 2 weeks following calcineurin inhibitor modification.

The patient had undergone HSCT for T-cell acute lymphoblastic leukemia. His post-transplant course was complicated by multiple episodes of steroid-refractory grade 4 GVHD, cytomegalovirus infection, and HSCT-TMA.

After 2 prior episodes of GVHD, the patient presented with bloody diarrhea. Intestinal biopsy demonstrated both HSCT-TMA and GVHD. No infections were identified.

The patient also had new-onset neurological symptoms of paresthesias, tetraparesis, and a neurogenic bladder, which have been reported as neurological manifestations of GVHD and TMA.

The patient was unable to walk due to the tetraparesis and required blood transfusions at least once daily. Hematological markers demonstrated HSCT-TMA with thrombocytopenia, elevated lactate dehydrogenase, and schistocytes.

Two weeks prior to starting OMS721, the patient’s immunosuppression (cyclosporine) had been decreased, and, given his history of steroid-refractory GVHD, he was receiving only low-dose corticosteroids. He received no other GVHD treatment.

After 2 OMS721 doses, the patient’s bloody diarrhea resolved, and his hematological markers improved. After 4 OMS721 doses, he was able to walk with help.

The patient completed 8 weeks of OMS721 treatment and has been doing well at home. All signs and symptoms of HSCT-TMA and all clinical symptoms of GVHD have resolved. His neurological symptoms have continued to improve.

“This patient’s marked response to OMS721 treatment was very gratifying,” said Anna Grassi, MD, of Azienda Ospedaliera Papa Giovanni XXIII in Bergamo, Italy.

“The cause of his neurological symptoms is not clear but may be a manifestation of GVHD or other endothelial injury. Prior to OMS721 treatment, this patient was deteriorating and at high risk for early death. The improvement of GVHD, H[S]CT-TMA, and the neurological symptoms following OMS721 treatment is promising.”

EMA recommends orphan designation for G100 to treat FL

 

follicular lymphoma
Micrograph showing

 

The European Medicines Agency’s (EMA’s) Committee for Orphan Medicinal Products has recommended orphan designation for G100 for the treatment of follicular lymphoma (FL).

 

G100 contains the synthetic small molecule toll-like receptor-4 agonist glucopyranosyl lipid A.

 

G100 works by activating innate and adaptive immunity in the tumor microenvironment to generate an immune response against the tumor’s pre-existing antigens.

 

Clinical and preclinical data have demonstrated G100’s ability to activate tumor-infiltrating lymphocytes, macrophages, and dendritic cells, and promote antigen-presentation and the recruitment of T cells to the tumor.

 

The induction of local and systemic immune responses has been shown in preclinical studies to result in local and abscopal tumor control.

 

Immune Design, the company developing G100, is currently evaluating G100 plus local radiation, with or without pembrolizumab, in a phase 1/2 trial of FL patients.

 

Results from this trial were presented at the 2017 ASCO Annual Meeting (abstract 7537). Nine patients who received G100 (3 patients each at the 5, 10, or 20 μg dose) with radiation (but not pembrolizumab) were evaluable for safety and efficacy.

 

The overall response rate was 44%, and all of these were partial responses (n=4). Thirty-three percent of patients had stable disease (n=3).

 

Among the responders, tumor regression ranged from 58% to 89%, which included up to 56% shrinkage of abscopal sites. Tumor biopsies showed increased inflammatory responses and T-cell infiltrates in abscopal tumors.

 

An additional 13 patients treated at the 10 μg dose were evaluable for safety.  There were no dose-limiting toxicities, serious adverse events (AEs), or grade 3/4 AEs observed.

 

Common AEs included injection site disorders, abdominal pain/discomfort, nausea, pruritus, and decrease in lymphocytes.

 

Immune Design said that, if this trial produces a sufficiently robust clinical benefit for patients, the company may pursue FL as the first indication for regulatory approval of G100.

 

About orphan designation

 

Orphan designation provides regulatory and financial incentives for companies to develop and market therapies that treat life-threatening or chronically debilitating conditions affecting no more than 5 in 10,000 people in the European Union, and where no satisfactory treatment is available.

 

Orphan designation provides a 10-year period of marketing exclusivity if the drug receives regulatory approval.

 

The designation also provides incentives for companies seeking protocol assistance from the EMA during the product development phase and direct access to the centralized authorization procedure.

 

The EMA’s Committee for Orphan Medicinal Products adopts an opinion on the granting of orphan drug designation, and that opinion is submitted to the European Commission for a final decision. The commission typically makes a decision within 30 days of the submission.

Intellectual impairment seems not a risk of asymptomatic cCMV

Bridging the gaps in CMV knowledge

Thu, 12/06/2018 - 18:48

 

Infants with congenital cytomegalovirus (cCMV) who were asymptomatic at birth with normal hearing by age 2 years were not at higher risk of intellectual impairment or low academic achievement, compared with controls, but patients with sensorineural hearing loss may experience more difficulty, according to a longitudinal study.

Full-scale intelligence, language, and academic achievement was evaluated in 78 adolescents with cCMV and normal hearing, 11 with cCMV and sensorineural hearing loss (SNHL) by age 2 years, and 40 controls. Mean full-scale intelligence scores did not vary among the patients with normal hearing and the controls, said Adriana S. Lopez of the National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, Atlanta, and her coauthors. Each group scored a mean 108 (95% confidence interval, 105-110 and 104-111, respectively) at age 5 years and 111 (95% CI, 108-114 and 107-104, respectively) at age 18 years (P = .96). The scores of the patients with SNHL, however, were 7 points lower at both times (P less than .05).

Similarly, the investigators reported that the difference in receptive vocabulary scores between cCMV patients with normal hearing and controls was not statistically significant (P = .36), but patients with SNHL scored 13 points lower than the controls (P less than .05).

In the other categories (expressive vocabulary and academic achievement in math and reading), the differences between the three groups were not statistically significant (P less than .05 for all three categories), suggesting that the other scores may underestimate the full intellectual potential of cCMV patients with SNHL, according to the researchers (Pediatrics. 2017. doi: 10.1542/peds.2017-1517).

“Findings from our study suggest that the majority of children [with cCMV] that would be identified by newborn screening do not appear to be at increased risk of intellectual impairment and, therefore, may not need long-term monitoring for cognitive impairment and/or disabilities,” Dr. Lopez and her coauthors wrote. “This information could provide reassurance to parents.”

“Further studies are needed to better understand the impact of asymptomatic congenital CMV infection on behavior and specific cognitive domains such as attention, perception, and memory,” they concluded.

The study was funded by the National Institutes of Health and was supported in other ways by a number of other organizations. Dr. Lopez and her coauthors reported no financial disclosures.

Body

 

Congenital cytomegalovirus (cCMV) infection is a leading nongenetic cause of hearing loss and neurodevelopmental disability, with the number of infants experiencing these symptoms approaching that of those with Down Syndrome and exceeding that of those with fetal alcohol syndrome, spina bifida, and childhood infections such as HIV. Most infected infants are asymptomatic, and the majority are not recognized at birth.

Yet little is known about intellectual outcomes and academic performance in these children. Lopez et al. provide encouraging findings and new insights that begin to bridge this gap in knowledge about children with asymptomatic cCMV up into adolescence.

There were some challenges in this study, including the large percentage of children whose mothers have medium to high socioeconomic status and the selection of appropriate controls. Although the controls were born within 6 days of the infants with cCMV, they were not matched for other demographic factors. It will be important to confirm these findings in children with families of lower socioeconomic status.

That said, this study is helpful in defining the disease burden from this common prenatal infection and in reassuring patients and doctors that these infants are not at increased risk for disabilities in terms of intellectual attainment and academic performance.

Suresh B. Boppana, MD, is a professor of pediatrics and microbiology, and Karen B. Fowler, DrPH, is a professor of epidemiology. Both practice at the University of Alabama in Birmingham. These remarks accompanied the Lopez et al. article (Pediatrics. 2017. doi: 10.1542/peds.2017-2526). Neither author reported any financial disclosures.

Body

 

Congenital cytomegalovirus (cCMV) infection is a leading nongenetic cause of hearing loss and neurodevelopmental disability, with the number of infants experiencing these symptoms approaching that of those with Down Syndrome and exceeding that of those with fetal alcohol syndrome, spina bifida, and childhood infections such as HIV. Most infected infants are asymptomatic, and the majority are not recognized at birth.

Yet little is known about intellectual outcomes and academic performance in these children. Lopez et al. provide encouraging findings and new insights that begin to bridge this gap in knowledge about children with asymptomatic cCMV up into adolescence.

There were some challenges in this study, including the large percentage of children whose mothers have medium to high socioeconomic status and the selection of appropriate controls. Although the controls were born within 6 days of the infants with cCMV, they were not matched for other demographic factors. It will be important to confirm these findings in children with families of lower socioeconomic status.

That said, this study is helpful in defining the disease burden from this common prenatal infection and in reassuring patients and doctors that these infants are not at increased risk for disabilities in terms of intellectual attainment and academic performance.

Bridging the gaps in CMV knowledge

Infants with congenital cytomegalovirus (cCMV) who were asymptomatic at birth with normal hearing by age 2 years were not at higher risk of intellectual impairment or low academic achievement, compared with controls, but patients with sensorineural hearing loss may experience more difficulty, according to a longitudinal study.

Full-scale intelligence, language, and academic achievement was evaluated in 78 adolescents with cCMV and normal hearing, 11 with cCMV and sensorineural hearing loss (SNHL) by age 2 years, and 40 controls. Mean full-scale intelligence scores did not vary among the patients with normal hearing and the controls, said Adriana S. Lopez of the National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, Atlanta, and her coauthors. Each group scored a mean 108 (95% confidence interval, 105-110 and 104-111, respectively) at age 5 years and 111 (95% CI, 108-114 and 107-104, respectively) at age 18 years (P = .96). The scores of the patients with SNHL, however, were 7 points lower at both times (P less than .05).

Similarly, the investigators reported that the difference in receptive vocabulary scores between cCMV patients with normal hearing and controls was not statistically significant (P = .36), but patients with SNHL scored 13 points lower than the controls (P less than .05).

In the other categories (expressive vocabulary and academic achievement in math and reading), the differences between the three groups were not statistically significant (P less than .05 for all three categories), suggesting that the other scores may underestimate the full intellectual potential of cCMV patients with SNHL, according to the researchers (Pediatrics. 2017. doi: 10.1542/peds.2017-1517).

“Findings from our study suggest that the majority of children [with cCMV] that would be identified by newborn screening do not appear to be at increased risk of intellectual impairment and, therefore, may not need long-term monitoring for cognitive impairment and/or disabilities,” Dr. Lopez and her coauthors wrote. “This information could provide reassurance to parents.”

“Further studies are needed to better understand the impact of asymptomatic congenital CMV infection on behavior and specific cognitive domains such as attention, perception, and memory,” they concluded.

The study was funded by the National Institutes of Health and was supported in other ways by a number of other organizations. Dr. Lopez and her coauthors reported no financial disclosures.

GIs take on Capitol Hill

Mon, 10/23/2017 - 16:50

 

During AGA’s annual Joint Committee weekend, 55 AGA members collectively attended 79 meetings with staff from the offices of their House representatives and senators, lobbying for the top concerns of gastroenterologists across the country, including:

  • Continued coverage of patients through either the Affordable Care Act or another bill that has the patient’s best interests in mind. More specifically, one that provides coverage for those with pre-existing conditions and for children under their parents’ plan until 26 years of age, among many other important provisions.
  • Changes in health care language that label a colonoscopy for cancer screening as “therapeutic,” which renders a large copay for patients.
  • Increased funding for the NIH.

Participants shared experiences from their time on Capitol Hill in the AGA Community forum, and encouraged others to get involved. Here are some of their reasons why.

  • Your voice matters: You are constituents – which translates to votes in the minds of representatives and senators – and providing face-to-face conversation with their staffers shows them that you care about your patients and their needs, explains Siddharth Singh, MD.
  • Being consistent gets your foot in the door: Some staffers recognized and remembered previous Advocacy Day participants, like Peter Liang, MD, MPH. Personally connecting could lead to follow-up communication and advocacy efforts, says Sarah Streett, MD, AGAF.
  • You’re indirectly (and sometimes directly) connecting with decision makers: Staff members from these offices work closely with the legislators who evaluate which policies to support or oppose. “So it’s important to come to Washington, build relationships, and make the case for our science, our specialty, and our patients,” says Kim Barrett, PhD, AGAF.
  • Others could be advocating against you on the same issues: “I very strongly believe that it is important to keep letting our legislators know how we feel and what we believe in,” shares Deborah Proctor, MD, AGAF.
  • It’s a rewarding experience: “Voice [your] concerns to your representatives who embrace the stories of how their decisions and policies affect your patients, practice, research, and institution,” explains Susan Ramdhaney, MD, AGAF.
  • It’s a critical time to take action: With the current health care environment, gastroenterologists need to express the needs of their patients and profession, Dr. Streett explains.

Localized wheezing differs from asthmatic, viral wheezing

Article Type

Fri, 01/18/2019 - 17:07

 

CHICAGO – Nearly half of all children have wheezing in their first year of life, and one in five have recurrent wheezing episodes, but that doesn’t mean they have asthma, explained Erik Hysinger, MD, MS, of the division of pulmonary medicine at Cincinnati Children’s Hospital.

Localized wheezing is not consistent with asthmatic or viral wheezing, which is typically diffuse and polyphonic, Dr. Hysinger emphasized at the annual meeting of the American Academy of Pediatrics.

“Localized wheezing is less common than diffuse wheezing and typically has a homophonous sound,” Dr. Hysinger said. It also usually arises from a central airway pathology. “High flow rates create loud amplitude sounds.”

iStock/Thinkstock
He discussed different presentations of localized wheezing and reviewed the three categories of differential diagnosis for nonasthmatic, nonviral wheezing: airway occlusion, airway narrowing, or airway compression.

Dr. Hysinger also covered management strategies for focal wheezing, starting with an initial trial of bronchodilators. Any wheezing resulting from a central airway problem, however, isn’t likely to respond to bronchodilators. Standard work-up for any of these causes is usually a chest x-ray, often paired with a bronchoscopy. Persistent wheezing likely needs a chest CT, and many of these conditions will require referral to a subspecialist.

Airway occlusion diagnoses

Four potential causes of an airway blockage are a foreign body, a bronchial cast, mucous plugs, or airway tumors.

A foreign body typically occurs with a cough, wheezing, stridor, and respiratory distress. It is most common in children under age 4 years, usually in those without a history of aspiration, yet providers initially misdiagnose more than 20% of patients with a foreign body. The foreign object – often coins, food, or batteries – frequently ends up in the right main bronchus and may go undetected up to a month, potentially leading to pneumonia, abscess, atelectasis, bronchiectasis, or airway erosion.

Dr. Erik Hysinger
The recommended initial evaluation, a bilateral decubitus chest x-ray, nevertheless cannot rule out a foreign body on its own because the objects may not show up on the films and only two-thirds of cases show an asymmetric hyperinflation. Physicians who suspect that a foreign body may be causing the wheeze should conduct a bronchoscopy. Obviously, the treatment is to remove the object, but providers also should expect to treat possible comorbidities if it took a while to identify and extract the object.

An endobronchial cast is rarer than a foreign body, but can be large enough to completely fill a lung with branching mucin, fibrin, and inflammatory cells. The wheezing sounds homophonous, with a barky or brassy cough accompanied by atelectasis. Dr. Hysinger recommended ordering chest x-ray, echocardiogram, and bronchoscopy. Although often idiopathic, these casts also can result from asthma or another disease: neutrophilic inflammation typically indicates a heart condition whereas asthma or influenza leads to eosinophilic inflammation.

Treatment should involve clearing the airway, followed by hypertonic saline, an inhaled tissue plasminogen activator, and a bronchoscopy for extraction.

Although distinct from endobronchial casts, a mucus plug also presents with wheezing, a cough, and atelectasis, and potentially respiratory distress or failure, and hypoxemia. Mucus plugs are diagnosed with a chest x-ray and flexible bronchoscopy, and then treated by removing the plug and clearing the airway, hypertonic saline, and mucolytics.

The rarest cause of an airway blockage is an airway tumor, often mistaken for asthma. Benign causes include papillomatosis, hemangioma, and hamartomas, while potentially malignant causes include a carcinoid, mucoepidermoid carcinoma, inflammatory myofibromas, and granular cell tumors.

In addition to a chest x-ray and bronchoscopy, a chest CT scan plus a biopsy and resection are necessary to diagnose airway tumors. Treatment will depend on the specific type of tumor identified.

“Overall survival is excellent,” Dr. Hysinger said of children with airway tumors.

Airway narrowing diagnoses

Two possible diagnoses for an intrinsic airway narrowing include bronchomalacia, occurring in only 1 of 2,100 children, and bronchial stenosis.

In bronchomalacia – diagnosed primarily with bronchoscopy – the airway collapses from weakening of the cartilage and posterior membrane. Bronchomalacia sounds like homophonous wheezing with a barky or brassy cough, and it’s frequently accompanied by recurrent bronchitis and/or pneumonia. Intervention is rarely necessary when occurring on its own, but severe cases may require endobronchial stents. Dr. Hysinger also recommended considering ipratroprium instead of albuterol.

Bronchial stenosis involves a fixed narrowing of the bronchi and can be congenital – typically occurring with heart disease – or acquired after an intubation and suction trauma or bronchiolitis obliterans (“popcorn lung”). A chest x-ray and bronchoscopy again are standard, but MRI may be necessary as well. Aside from helping the patient clear the airway, bronchial stenosis typically needs limited management unless the patient is symptomatic. In that case, options include balloon dilation, endobronchial stents, or a slide bronchoplasty.

 

 

Airway compression diagnoses

An extrinsic airway compression could have a vascular cause or could result from pressure by an extrinsic mass or the axial skeleton.

Vascular compression usually occurs due to abnormal vasculature development, particularly with vascular stents, Dr. Hysinger said. The wheezing presents with stridor, feeding intolerance, recurrent infections, and cyanotic episodes. The work-up should include a chest x-ray, bronchoscopy, and a chest CT and/or MRI. A variety of interventions may be necessary to treat it, including an aortopexy, pulmonary artery trunk–pexy, arterioplasty, vessel implantation, or endobronchial stent. Residual malacia may remain after treatment, however.

The most common reasons for airway compression by some kind of mass is a reactive lymphadenopathy, a tumor, or an infection, including tuberculosis or histoplasmosis. Severe narrowing of the airway can lead to respiratory failure, but because the compression can develop slowly, the wheezing can be mistaken for asthma. In addition to a chest CT and bronchoscopy, a patient will need other work-ups depending on the cause. Possibilities include a biopsy, a gastric aspirate (for tuberculosis), a bronchoalveolar lavage, or antibody titers.

Similarly, because therapeutic intervention requires treating the underlying infection, specific treatments will vary. Tumors typically will need resection, chemotherapy, and/or radiation – and, until the airway is fully cleared, the patient may need chronic mechanical ventilation.

Children with severe scoliosis or kyphosis are those most likely to experience airway compression resulting from pressure by the axial skeleton, in which the spine’s curvature directly presses on the airway. In addition to the wheeze, these patients may have respiratory distress or recurrent focal pneumonia, Dr. Hysinger said. The standard work-up involves a chest x-ray, chest CT, spinal MRI, and bronchoscopy.

Consider using spinal rods, but they can both help the condition or potentially exacerbate the compression, Dr. Hysinger said. Either way, children also will need help with airway clearance and coughing.

Dr. Hysinger concluded by reviewing what you may consider changing in your current practice, including the initial trial of bronchodilators, a chest x-ray, and a subspecialist referral.

No funding was used for this presentation, and Dr. Hysinger reported having no relevant financial disclosures.

Two possible diagnoses for an intrinsic airway narrowing include bronchomalacia, occurring in only 1 of 2,100 children, and bronchial stenosis.

In bronchomalacia – diagnosed primarily with bronchoscopy – the airway collapses from weakening of the cartilage and posterior membrane. Bronchomalacia sounds like homophonous wheezing with a barky or brassy cough, and it’s frequently accompanied by recurrent bronchitis and/or pneumonia. Intervention is rarely necessary when occurring on its own, but severe cases may require endobronchial stents. Dr. Hysinger also recommended considering ipratroprium instead of albuterol.

Bronchial stenosis involves a fixed narrowing of the bronchi and can be congenital – typically occurring with heart disease – or acquired after an intubation and suction trauma or bronchiolitis obliterans (“popcorn lung”). A chest x-ray and bronchoscopy again are standard, but MRI may be necessary as well. Aside from helping the patient clear the airway, bronchial stenosis typically needs limited management unless the patient is symptomatic. In that case, options include balloon dilation, endobronchial stents, or a slide bronchoplasty.

 

 

Airway compression diagnoses

An extrinsic airway compression could have a vascular cause or could result from pressure by an extrinsic mass or the axial skeleton.

Vascular compression usually occurs due to abnormal vasculature development, particularly with vascular stents, Dr. Hysinger said. The wheezing presents with stridor, feeding intolerance, recurrent infections, and cyanotic episodes. The work-up should include a chest x-ray, bronchoscopy, and a chest CT and/or MRI. A variety of interventions may be necessary to treat it, including an aortopexy, pulmonary artery trunk–pexy, arterioplasty, vessel implantation, or endobronchial stent. Residual malacia may remain after treatment, however.

The most common reasons for airway compression by some kind of mass is a reactive lymphadenopathy, a tumor, or an infection, including tuberculosis or histoplasmosis. Severe narrowing of the airway can lead to respiratory failure, but because the compression can develop slowly, the wheezing can be mistaken for asthma. In addition to a chest CT and bronchoscopy, a patient will need other work-ups depending on the cause. Possibilities include a biopsy, a gastric aspirate (for tuberculosis), a bronchoalveolar lavage, or antibody titers.

Similarly, because therapeutic intervention requires treating the underlying infection, specific treatments will vary. Tumors typically will need resection, chemotherapy, and/or radiation – and, until the airway is fully cleared, the patient may need chronic mechanical ventilation.

Children with severe scoliosis or kyphosis are those most likely to experience airway compression resulting from pressure by the axial skeleton, in which the spine’s curvature directly presses on the airway. In addition to the wheeze, these patients may have respiratory distress or recurrent focal pneumonia, Dr. Hysinger said. The standard work-up involves a chest x-ray, chest CT, spinal MRI, and bronchoscopy.

Consider using spinal rods, but they can both help the condition or potentially exacerbate the compression, Dr. Hysinger said. Either way, children also will need help with airway clearance and coughing.

Dr. Hysinger concluded by reviewing what you may consider changing in your current practice, including the initial trial of bronchodilators, a chest x-ray, and a subspecialist referral.

Driving ability of Parkinson’s patients can decline quickly

The progression of Parkinson’s disease over 2 years takes a toll on the driving skills of even drivers who initially perform as well as healthy age-matched drivers, according to a longitudinal cohort study conducted by Urgun Uc, MD, and associates.

While some patients with Parkinson’s disease who took part in a test of driving skills on a standardized driving course performed significantly worse at a baseline assessment than did healthy control patients, the patients who performed at a similar level as the control group made a significantly higher number of driving mistakes 2 years later on a follow-up evaluation.

Overall, at baseline, 67 Parkinson’s disease patients committed more road safety errors and also performed worse on visual, cognitive, and motor tests than did 110 members of the control group. At baseline, the Parkinson’s disease group made an average of 40.6 road safety errors, and the control group made 32.9 mistakes.

Among the original 67 Parkinson’s disease patients, the 28 who returned for repeat testing at 2 years had performed just as well at baseline as the 69 control group returnees. But at the 2-year follow-up, the Parkinson’s disease group made an average of 49.7 mistakes, while the control group made 34.6 mistakes.

In addition to an increase in overall driving errors, Parkinson’s disease patients also made a significantly higher number of lane observance, overtaking, turning, miscellaneous, and serious errors after 2 years than did the control group. Risk factors for worse performance after 2 years included greater error count and worse visual acuity at baseline, and worsening of global cognition, Unified Parkinson’s Disease Rating Scale scores, executive function, visual-processing speed, and attention.

“Health care providers for patients with Parkinson’s disease should routinely inquire about driving status and make necessary referrals for evaluation of driving fitness as needed. Further research is needed to determine if improvement of underlying impairments in visual perception, executive function, and motor abilities through physical exercise and cognitive training can preserve driving ability in Parkinson’s disease for a longer time,” the investigators concluded.
