The people behind the Journal really matter
Our goal at the Cleveland Clinic Journal of Medicine is to provide timely, readily digestible, and useful clinical information to our readers. To do so, we need authors who buy into our educational mission, but we also need conscientious peer reviewers and an editorial staff capable of turning “doctorese” into readily understood English.
Our physician deputy editors Pelin Batur and James Pile solicit articles, guide authors, draft and revise CME questions, and assist greatly in the peer review process. Our nonphysician editors edit manuscripts to achieve a consistent editorial style in all of our published papers, but they serve many other key functions. They manage the business of publishing a monthly journal at a time of drastically shrinking advertising revenue, they ensure that Journal content complies with rules for CME material published in print and online, and they keep up with continuous changes in online publishing. The Journal receives significant funding from Cleveland Clinic’s Education Institute, funding we need to pursue our role as an independent, peer-reviewed conveyer of clinical information.
I write this to emphasize that real people manage all of these tasks, and to gratefully acknowledge two people who are leaving the Journal: Mr. Joseph Dennehy and Dr. James Pile.
Long-time sales and marketing director Joe Dennehy played a key role in the Journal’s rise from relative obscurity about 20 years ago. This period was marked by many hospital-based journals closing up shop. Published since 1931, the Journal was relaunched in 1995 as a resource for postgraduate medical education with a national and international reach. Joe was brought in to guide and implement the marketing of the Journal as an independent, high-quality, clinical educational journal to increase its attractiveness as an advertising medium for the pharmaceutical industry so we could at least partly defray the significant expenses of publishing.
Joe is well known to medical publishers and media buyers, and over the past 20 years he became the face of the Journal in sales and marketing circles. In 2010, the Association of Medical Media recognized Joe’s achievements at its 18th Annual Nexus Representatives of the Year Awards, which acknowledge outstanding sales and marketing directors for their superior service, professionalism, and communication of ideas. Joe exemplifies these qualities and has been an inspiration to those of us who know and work with him. He has fully understood the sincerity of our mission and has never asked us to stray from it. Although Joe and his wife Holly live in New York, they are part of the Cleveland-based Journal family, and we will miss them. We wish them happiness and good health.
Dr. James Pile is an internal medicine hospitalist, an infectious disease specialist, and a superior medical educator. His work with us for the past several years has enhanced the Journal’s educational value for practicing hospitalists. His working familiarity with clinical leaders in the Society of Hospital Medicine has provided us with willing and skilled peer reviewers. Jim is now transitioning to a role as director of the internal medicine residency program at MetroHealth Medical Center, also here in Cleveland. He will continue to be a clinical resource for us as author and reviewer, but his ever-calm demeanor and clinical common sense will be hard to replace.
The Journal continues to evolve with the publishing times. We are assuming a greater presence in the digital world and adjusting to an environment of ever-diminishing advertising revenue. But with the work of our editorial team (I invite you to periodically glance at our masthead to note our team of writers, managers, and production staff), we intend to stay true to our educational mission. Our personal thanks to Joe and Jim for their contributions of the past, and to our current team in Scientific Publications for their ongoing and very personal commitment to providing the highest quality medical education that we can.

In which clinical situations can the use of the 52-mg levonorgestrel-releasing IUD (Mirena) and the TCu380A copper-IUD (ParaGard) be extended?
One of the most important medical interventions to improve maternal-child health is providing effective contraception to men and women of reproductive age. The 52-mg levonorgestrel-intrauterine device (LNG-IUD; Mirena) is one of the most effective forms of reversible contraception available to women, with a failure rate of 1.1% over 5 years of use.1 The TCu380A copper-IUD (ParaGard), another highly effective reversible contraceptive, is reported to have failure rates of approximately 1.4% and 2.2%, over 5 and 10 years of use.2
An interesting question is whether—in certain clinical situations—a single IUD can be used for longer than the currently recommended 5 and 10 years for a Mirena IUD and a ParaGard IUD, respectively.
The LNG-IUD containing 52 mg LNG may be effective up to 7 years
The US Food and Drug Administration (FDA) package insert for the Mirena 52-mg LNG-IUD states that the device is “indicated for contraception for up to 5 years. Thereafter if continued contraception is desired, the system should be replaced.”1 The FDA package insert for the levonorgestrel-releasing intrauterine system, Liletta 52-mg LNG-IUD, states that it is “indicated for prevention of pregnancy up to 3 years.”3 The FDA guidance is based on data submitted to the agency by the manufacturers to support the approval process. Completing large-scale clinical trials that extend past 5 years or more is challenging, because of the cost and the loss of study participants to follow-up. Hence, few clinical trials of contraceptive IUDs continue for more than 5 to 10 years.
Although the FDA-approved indication for Mirena and Liletta is 5 and 3 years, respectively, evidence suggests that the 52-mg LNG-IUD is an effective contraceptive beyond 5 years. In fact, multiple studies report that this IUD is an effective contraceptive for at least 6 or 7 years (TABLE 1).4–9 Among 895 women using the 52-mg LNG-IUD for 6 to 7 years, only 1 pregnancy was reported in the last year of use. In that case, the IUD was in the cervix and partially expelled from the uterus.8 These data indicate that the 52-mg LNG-IUD is likely an effective contraceptive for up to 7 years, with pregnancy rates below 1% in the last year of use.
The TCu380A copper-IUD is effective up to 12 years
The currently available TCu380A copper-IUD (ParaGard) is FDA approved for 10 years.2 Studies evaluating the efficacy of this copper-IUD are limited, but those that have been published reported that it is effective for at least 12 years and possibly up to 20 years (TABLE 2).10−13
Recently I saw a patient who had a copper-IUD (ParaGard, TCu380A) inserted as a teen after a birth, and had successfully used the same device for 17 years. She presented for removal of the IUD so that she could attempt conception. After removal of the IUD, copper wire was visible on the device. Long-term studies of the TCu220 copper-IUD, which contains less copper than the ParaGard, report pregnancies with the use of the device beyond 10 years.12 These devices, which are not available in the United States, should not be used past their recommended interval.

Introducing Dr. Tyler G. Hughes
I feel honored to join Tyler G. Hughes as co-Editor of the ACS Surgery News and I am excited to work with its Managing Editor, Therese Borden, to bring to its readers breaking information on a broad range of subjects of interest and importance to practicing surgeons. Although we have a great challenge to fill the giant shoes of our immediate predecessor, Layton “Bing” Rikkers, we will do our best to address the vexing clinical, economic, social, and administrative challenges that continue to confront us no matter what our practice type and setting.
I could not ask for a more accomplished and versatile co-Editor than Tyler Hughes. As a general surgeon practicing in the truly rural setting of McPherson, Kan., since 1995, he became an articulate spokesman for rural surgeons across the country during his tenure on the ACS Board of Governors as Kansas’ at-large member. As the crisis in access to general surgical care for rural Americans became increasingly evident, Tyler was asked to speak to the Board of Regents in February 2012, and the first new Advisory Council in 50 years was formed: the Advisory Council for Rural Surgery (ACRS), of which Tyler was named the first Chair. In 4 short years, the ACRS has become a force to promote better communication among rural surgeons and to call attention to the needs of them and their patients.
Tyler’s communication skills have also been put to great use in his role as Editor of the ACS Web Portal and as the inaugural Editor-in-Chief of the ACS Communities, an activity that has met with incredible success in promoting communication among the far-flung individual surgeons who constitute the ACS membership.

I could not ask for a more accomplished and versatile co-Editor than Tyler Hughes. As a general surgeon practicing in the truly rural setting of McPherson, Kan., since 1995, he became an articulate spokesman for rural surgeons across the country during his tenure on the ACS Board of Governors as Kansas’ at-large member. As the crisis in access to general surgical care for rural Americans became increasingly evident, Tyler was asked to speak to the Board of Regents in February 2012, and the first new Advisory Council in 50 years was formed: the Advisory Council for Rural Surgery (ACRS), of which Tyler was named the first Chair. In 4 short years, the ACRS has become a force to promote better communication among rural surgeons and to call attention to the needs of them and their patients.
Tyler’s communication skills have also been put to great use in his role as Editor of the ACS Web Portal and as the inaugural Editor-in-Chief of the ACS Communities, an activity that has met with incredible success in promoting communication among the far-flung individual surgeons who constitute the ACS membership. Along the way, he has also served as an Associate Editor of “Selected Readings in General Surgery” and a member of the steering committee of Evidence Based Reviews in Surgery.

Introducing Dr. Karen Deveney
As Layton “Bing” Rikkers leaves his post as Editor of ACS Surgery News, it has fallen to Karen Deveney and me to shepherd the paper forward as co-Editors. Dr. Rikkers felt that a combination approach of an academic surgeon and a community surgeon would bring balance to ACS Surgery News that would be representative of the nature of the American College of Surgeons (ACS).
In Karen Deveney we have an accomplished academic surgeon who has wide ranging interests in and out of surgery. Karen was raised in rural Oregon, went to Stanford for undergraduate education, and did her medical school and residency at University of California, San Francisco. Among her cohort in those times of training and her early academic career were Donald Trunkey, George Sheldon, and Brent Eastman, all of whom, like Karen, went on to have a major impact in the world of surgery.
After a stint in the military serving in Germany with her surgeon husband Cliff, Karen eventually landed at Oregon Health and Science University where she went on to serve as Program Director for 20 years at one of the best general surgery training programs in the country. She served as Second Vice-President of the ACS and is the immediate past-President of the Pacific Coast Surgical Association.
Her CV reflects varied academic interests and activities. So, Karen’s contributions to academic surgery are outstanding. But in Karen we also get a person who is alive to the needs of the population beyond the walls of her major medical center. Karen has been a leader in the march to save surgical access for rural populations. She is a founding member of the ACS Advisory Council for Rural Surgery, serving as the Education Pillar Chair of that Council. In her own institution, Karen is a pioneer in developing a model rural surgery track for general surgery residents – first in Grants Pass, Ore. and then in Coos Bay, Ore.
She has been a hardworking general and colorectal surgeon for over 30 years. And, like almost all dedicated surgical educators, she has taken call – enduring the long call schedule of her residents throughout her career.
Karen and I hope to make a good team in this new effort. We are different in many ways, but very much the same in others. We plan a synergy that will unflinchingly recognize the challenges in surgery and facilitate positive discussion and reporting of the solutions for those challenges. Among those challenges are the changing economic structure of surgery, the facilitation of useful quality efforts, and most importantly, the rapid dissemination of significant clinical and scientific information vital to surgeons everywhere.
Dr. Hughes is an ACS Fellow with the department of general surgery, McPherson Hospital, McPherson, Kan., and is the Editor in Chief of ACS Communities. He is also Associate Editor for ACS Surgery News.

Protecting the newborn brain—the final frontier in obstetric and neonatal care
During the past 40 years neonatologists have discovered new treatments to improve pulmonary and cardiovascular care of preterm newborns, resulting in a dramatic reduction in newborn mortality and childhood morbidity. Important advances include glucocorticoid administration to mothers at risk for preterm birth, surfactant and nitric oxide administration to the newborn, kangaroo (or skin-to-skin) care, continuous positive airway pressure, and high-frequency ventilation.1 In 1960, only 5% of 1,000-g newborns survived. In 2000, 95% of 1,000-g newborns survive.1
The successes in pulmonary and cardiovascular care have revealed a new frontier in neonatal care: the prevention of long-term neurologic disability by the early treatment of newborn encephalpathy with therapeutic hypothermia. This novel undertaking is an important one; approximately 1 in 300 newborns are diagnosed with encephalopathy.2
Until recently there were no proven treatments for newborns with encephalopathy. However, therapeutic hypothermia now has been proven to be an effective intervention for the treatment of moderate and severe encephalopathy,3,4 and its use is expanding to include mild cases.
This increased use can lead to more complex situations arising for obstetricians, for when a neonatologist decides to initiate therapeutic hypothermia of a newborn the parents may wonder if the obstetrician’s management of labor and delivery was suboptimal, contributing to their baby’s brain injury.
Therapeutic hypothermia: The basics
First, we need to define therapeutic hypothermia. Both head hypothermia and whole-body hypothermia are effective techniques for the treatment of newborn encephalopathy.3,4 Most centers use whole-body (FIGURE) rather than head, hypothermia because it facilitates access to the head for placement of electroencephalogram (EEG) sensors.
The key principles of therapeutic hypothermia include5,6:
- Initiate hypothermia within 6 hours of birth.
- Cool the newborn to a core temperature of 33.5° to 34.5°C (92.3° to 94.1°F). Some centers focus on achieving consistent core temperatures of 33.5°C (92.3°F).
- Monitor core temperature every 5 to 15 minutes.
- Cool the newborn for 72 hours.
- Obtain head ultrasonography to detect intracranial hemorrhage.
- Initiate continuous or intermittent EEG monitoring.
- Treat seizures with phenobarbital, lorazepam, or phenytoin.
- Obtain blood cultures, a complete blood count, blood gas concentrations, alactate coagulation profile, and liver function tests.
- Sedate the newborn, if necessary.
- Minimize oral feedings during the initial phase of hypothermia.
- Obtain sequential magnetic resonance imaging (MRI) studies to assess brain structure and function.
- For all newborns with suspected encephalopathy, the placenta should be sent to pathology for histologic study.7
The data on therapy effectivenessTwo recent meta-analyses independently reported that therapeutic hypothermia reduced the risk of newborn death and major neurodevelopmental disability.3,4 The Cochrane meta-analysis reported that the therapy reduced the risk of neuromotor delay, developmental delay, cerebral palsy, and abnormal MRI results (TABLE).4 The study authors also reported that therapeutic hypothermia reduced the risk of blindness and deafness, although these effects did not reach statistical significance.4 Therapeutic hypothermia did increase the risk of newborn sinus bradycardia and thrombocytopenia.3,4 Compared with usual care, the therapy increased the average survival rate with a normal neurologic outcome at 18 months from 23% to 40%.3 It should be noted that even with therapeutic hypothermia treatment, many newborns with moderate to severe encephalopathy have long-term neurologic disabilities.
Indications for therapeutic hypothermia are expandingIn the initial clinical trials of therapeutic hypothermia, newborns with moderate to severe encephalopathy were enrolled. Typical inclusion criteria were: gestational age ≥35 or 36 weeks, initiation of therapeutic hypothermia within 6 hours of birth, pH ≤7.0 or base deficit of ≥16 mEq/L, 10-minute Apgar score <5 or ongoing resuscitation for 10 minutes, and moderate to severe encephalopathy on clinical examination.3,4 Typical exclusion criteria were: intrauterine growth restriction with birth weight less than 1,750 g, severe congenital anomalies or severe genetic or metabolic syndromes, major intracranial hemorrhage, sepsis, or persistent coagulopathy.
Given the success of therapeutic hypothermia for moderate to severe newborn encephalopathy, many neonatologists are expanding the indications for treatment. In some centers current indications for initiation of hypothermia include the following:
- gestational age ≥34 weeks
- suspicion of encephalopathy or a seizure event
- any obstetric sentinel event (including a bradycardia, umbilical cord prolapse, uterine rupture, placental abruption, Apgar score ≤5 at 10 minutes, pH ≤7.1 or base deficit of ≥10 mEq/L or Category III tracing, or fetal tachycardia with recurrent decelerations or fetal heart rate with minimal variability and recurrent decelerations).
Suspicion for encephalopathy might be triggered by any of a large number of newborn behaviors: lethargy, decreased activity, hypotonia, weak suck or incomplete Moro reflexes, constricted pupils, bradycardia, periodic breathing or apnea, hyperalertness, or irritability.8
Coordinate neonatology and obstetric communication with the familyGiven the expanding indications for therapeutic hypothermia, an increasing number of newborns will receive this treatment. This scenario makes enhanced communication vital. Consider this situation:
CASE Baby rushed for therapeutic hypothermia upon birthA baby is born limp and blue without a cry. Her hypotonia raises a concern for encephalopathy, and she is whisked off to the neonatal intensive care unit for 72 hours of therapeutic hypothermia. Stunned, the parents begin to wonder, “Will our baby be O.K.?” and “What went wrong?”
When neonatologists recommend therapeutic hypothermia for the newborn with presumptive encephalopathy, they may explain the situation to the parents with words such as brain injury, encephalopathy, hypoxia, and ischemia. Intrapartum events such as a Category II or III fetal heart rate tracing, operative vaginal delivery, or maternal sepsis or abruption might be mentioned as contributing factors. A consulting neurologist may mention injury of the cerebral cortex, subcortical white matter, or lateral thalami. The neonatologists and neurologists might not mention that less than 50% of cases of newborn encephalopathy are thought to be due to the management of labor.2
The obstetrician, as stunned by the events as the parents, may be at a loss about how to communicate effectively with their patient about the newborn’s encephalopathy. Obstetricians can help assure the parents of their continued involvement in the care and reinforce that the hospital’s neonatologists are superb clinicians who will do their best for the baby.
Challenges exist to effective communication. It is often difficult to optimally coordinate and align the communications of the neonatologists, neurologist, nurses, and obstetrician with the family. Communication with the family can be uncoordinated because interactions occur between the family and multiple specialists with unique perspectives and vocabularies. These conversations occur in sequence, separated in time and place. The communication between family and neonatologists typically occurs in the neonatal intensive care unit. Interactions between obstetrician and mother typically occur in the postpartum unit. The neonatologists and obstetricians are assigned to the hospital in rotating coverage shifts, increasing the number of hand-offs and physicians involved in the hospital care of the mother and newborn dyad.
A joint family meeting with the neonatologists, obstetrician, and family early in the course of newborn care might be an optimal approach to coordinating communication with the parents. Conflicting obligations certainly may make a joint meeting difficult to arrange, however.
Reducing the risk of permanent injury to the central and peripheral nervous system of the newborn is the goal of all obstetricians and neonatologists. Many authorities believe that therapeutic hypothermia can reduce the risk of death and major neurodevelopmental disorders in newborns with encephalopathy. Initial data are promising. If long-term follow-up studies prove that this therapy reduces neurologic disability, the treatment represents a major advance in maternal-child care. As we learn more about this novel, and potentially effective therapy, it should be on the minds of those involved with newborn care to involve the ObGyn in coordinated communication with the family and other medical staff.

The data on therapy effectivenessTwo recent meta-analyses independently reported that therapeutic hypothermia reduced the risk of newborn death and major neurodevelopmental disability.3,4 The Cochrane meta-analysis reported that the therapy reduced the risk of neuromotor delay, developmental delay, cerebral palsy, and abnormal MRI results (TABLE).4 The study authors also reported that therapeutic hypothermia reduced the risk of blindness and deafness, although these effects did not reach statistical significance.4 Therapeutic hypothermia did increase the risk of newborn sinus bradycardia and thrombocytopenia.3,4 Compared with usual care, the therapy increased the average survival rate with a normal neurologic outcome at 18 months from 23% to 40%.3 It should be noted that even with therapeutic hypothermia treatment, many newborns with moderate to severe encephalopathy have long-term neurologic disabilities.
Indications for therapeutic hypothermia are expandingIn the initial clinical trials of therapeutic hypothermia, newborns with moderate to severe encephalopathy were enrolled. Typical inclusion criteria were: gestational age ≥35 or 36 weeks, initiation of therapeutic hypothermia within 6 hours of birth, pH ≤7.0 or base deficit of ≥16 mEq/L, 10-minute Apgar score <5 or ongoing resuscitation for 10 minutes, and moderate to severe encephalopathy on clinical examination.3,4 Typical exclusion criteria were: intrauterine growth restriction with birth weight less than 1,750 g, severe congenital anomalies or severe genetic or metabolic syndromes, major intracranial hemorrhage, sepsis, or persistent coagulopathy.
Given the success of therapeutic hypothermia for moderate to severe newborn encephalopathy, many neonatologists are expanding the indications for treatment. In some centers current indications for initiation of hypothermia include the following:
- gestational age ≥34 weeks
- suspicion of encephalopathy or a seizure event
- any obstetric sentinel event (including a bradycardia, umbilical cord prolapse, uterine rupture, placental abruption, Apgar score ≤5 at 10 minutes, pH ≤7.1 or base deficit of ≥10 mEq/L or Category III tracing, or fetal tachycardia with recurrent decelerations or fetal heart rate with minimal variability and recurrent decelerations).
Suspicion for encephalopathy might be triggered by any of a large number of newborn behaviors: lethargy, decreased activity, hypotonia, weak suck or incomplete Moro reflexes, constricted pupils, bradycardia, periodic breathing or apnea, hyperalertness, or irritability.8
Coordinate neonatology and obstetric communication with the familyGiven the expanding indications for therapeutic hypothermia, an increasing number of newborns will receive this treatment. This scenario makes enhanced communication vital. Consider this situation:
CASE Baby rushed for therapeutic hypothermia upon birthA baby is born limp and blue without a cry. Her hypotonia raises a concern for encephalopathy, and she is whisked off to the neonatal intensive care unit for 72 hours of therapeutic hypothermia. Stunned, the parents begin to wonder, “Will our baby be O.K.?” and “What went wrong?”
When neonatologists recommend therapeutic hypothermia for the newborn with presumptive encephalopathy, they may explain the situation to the parents with words such as brain injury, encephalopathy, hypoxia, and ischemia. Intrapartum events such as a Category II or III fetal heart rate tracing, operative vaginal delivery, or maternal sepsis or abruption might be mentioned as contributing factors. A consulting neurologist may mention injury of the cerebral cortex, subcortical white matter, or lateral thalami. The neonatologists and neurologists might not mention that less than 50% of cases of newborn encephalopathy are thought to be due to the management of labor.2
The obstetrician, as stunned by the events as the parents, may be at a loss about how to communicate effectively with their patient about the newborn’s encephalopathy. Obstetricians can help assure the parents of their continued involvement in the care and reinforce that the hospital’s neonatologists are superb clinicians who will do their best for the baby.
Challenges exist to effective communication. It is often difficult to optimally coordinate and align the communications of the neonatologists, neurologist, nurses, and obstetrician with the family. Communication with the family can be uncoordinated because interactions occur between the family and multiple specialists with unique perspectives and vocabularies. These conversations occur in sequence, separated in time and place. The communication between family and neonatologists typically occurs in the neonatal intensive care unit. Interactions between obstetrician and mother typically occur in the postpartum unit. The neonatologists and obstetricians are assigned to the hospital in rotating coverage shifts, increasing the number of hand-offs and physicians involved in the hospital care of the mother and newborn dyad.
A joint family meeting with the neonatologists, obstetrician, and family early in the course of newborn care might be an optimal approach to coordinating communication with the parents. Conflicting obligations certainly may make a joint meeting difficult to arrange, however.
Reducing the risk of permanent injury to the central and peripheral nervous system of the newborn is the goal of all obstetricians and neonatologists. Many authorities believe that therapeutic hypothermia can reduce the risk of death and major neurodevelopmental disorders in newborns with encephalopathy. Initial data are promising. If long-term follow-up studies prove that this therapy reduces neurologic disability, the treatment represents a major advance in maternal-child care. As we learn more about this novel, and potentially effective therapy, it should be on the minds of those involved with newborn care to involve the ObGyn in coordinated communication with the family and other medical staff.

Trust the thyroid thermostat
Primary hypothyroidism is common. Most patients acquire it when the thyroid gland is damaged by autoimmune inflammation. It is readily and reliably treated with the orally administered synthetic hormone levothyroxine, or less reliably with thyroid gland extracts. Absorption of either medication is significantly influenced by food, so patients need to pay attention to the timing of ingestion. But occasional blood testing can be used to easily monitor the sufficiency of replacement therapy.
The predominant active thyroid hormone is triiodothyronine (T3), most of which is converted from thyroxine (T4) by deiodination outside of the thyroid gland. Circulating thyroid-binding globulins tie up significant amounts of these hormones in the blood, and this protein binding is affected by a number of factors. Free T3 and T4—not bound—are the substances that exert physiologic effects on target organs and also give feedback information to the pituitary gland which, completing the loop, releases thyroid-stimulating hormone (TSH) and ultimately controls the healthy thyroid gland’s production and release of its hormones. Hence, the total circulating thyroid hormone levels are not as biologically relevant as the free T3 and T4 levels. Even in the absence of a functioning thyroid gland, the TSH level reliably reflects the bioactivity of circulating thyroid hormones so long as the pituitary gland is functioning normally.
Routine tracking of the biologic effects of thyroid hormone, such as the metabolic rate, is unreasonable, and other biologic effects such as the cholesterol level are influenced by so many factors in addition to T3 as to be unreliable indicators of thyroid hormone levels. Assuming the patient’s hypothalamic-pituitary axis is normal, the most reasonable and reliable way to track the biologic effect of thyroid hormone is to follow the TSH level. Although the exact relationship between free thyroid hormone and TSH levels is slightly different between patients with normal thyroid glands and those with damaged glands receiving replacement therapy, TSH measurement is an excellent indicator of the level that the brain wants thyroid function to be. Other than in specific nonhomeostatic circumstances, the pituitary gland is usually a superb thermostat for thyroid hormone activity.
In this issue of the Journal, Dr. Christian Nasr discusses the rationale for routinely using TSH measurement alone to direct exogenous thyroid replacement, explaining why it is cost-effective and clinically appropriate.
While following T3 and T4 may occasionally be useful in a few patients, the wealth of clinical data does not support this practice. As a routine practice it is certainly financially wasteful, and may lead to inappropriate clinical decisions.
Why, then, do some physicians persist in regularly following T3 and T4 levels in addition to TSH? There is no single answer. Although some patients may feel “better” if they take a little more rather than a little less levothyroxine, whether this benefit outweighs the metabolic price in the long run is not at all clear. Plus, in the published experience with treating subclinical hypothyroidism,1 patients did not generally feel better or experience desired weight loss when they received slightly more exogenous thyroid hormone. Somewhat analogously, if the TSH level is already normal, increasing thyroid replacement to attain a free T3 or T4 level in the high-normal range is unlikely to improve clinical outcomes in a meaningful way and may well be detrimental in the long term.
Despite a lot of chatter on Internet blogs regarding the multiple benefits of selective T3 replacement and higher T3 levels, akin to testosterone supplementation above what the (normal functioning) hypothalamic-pituitary axis has determined to be biologically appropriate, there is limited clinical evidence to support this practice. When replacing the output of a diseased or absent thyroid gland, it is reasonable clinical practice to trust the pituitary readings of the thyroid thermostat.

Unresolved questions about the specialty lurk in the cortex of psychiatrists
But many of our own questions await an answer. The fact is that psychiatrists have serious, nagging questions—in every cortical fold of their collective brain—about patients’ welfare, psychiatric practice, and professional matters. Their questions about frustrations of daily practice deserve an honest and convincing response, yet go begging—expressed so well in songwriter Bob Dylan’s lyric, “The answer is blowin’ in the wind.”
What follows are long-standing “Why?” questions whose answers are still blowin’ in the wind. (Dylan didn’t specify which wind is blowin’, so I’ve provided the names of 22 atmospheric movements of air molecules in the Box. Take your pick!)
Why is a jail OK for the mentally ill but an asylum is not? Why is it necessary to put armed guards in charge of psychiatric patients instead of a multidisciplinary team of psychiatrists, primary care providers, nurses, social workers, psychologists, and pharmacists? Why has a brain disease, such as psychosis or bipolar disorder, become a punishable felony instead of a treatable illness?
Why did the system of mental health care degenerate to the point that a severely depressed or suicidal, or acutely psychotic, patient can be hospitalized for only 4 or 5 days, then must be discharged before her (his) illness has been fully controlled? Why do health care insurers exhibit that atrocious combination of maximum greed and minimal compassion?
Why does a completely unjustified and hurtful stigma continue to plague mental brain disorders, patients who suffer from them, mental health professionals, and the very discipline of psychiatry?
Why do otherwise intelligent people show compassion toward people with a brain disorder such as stroke, Parkinson’s disease, multiple sclerosis, myasthenia gravis, or migraine, but express aversion and even disdain for psychiatric brain disorders such as schizophrenia, depression, obsessive-compulsive disorder, and panic disorder?
And why does this prejudice persist despite advances in psychiatric neuroscience that have used neurogenetics, neuroimaging, and molecular studies to establish, without a doubt, the neurobiological basis of all psychiatric disorders.
Why are there still no objective diagnostic criteria for psychiatric disorders? Why do we persist in using defining symptoms that have been volunteered by patients—symptoms that can be subject to distortion or malingering? Why aren’t the hundreds of established biomarkers being incorporated into the diagnostic formulation, to lessen subjectivity and improve reliability and validity?
Why is off-label prescribing, the judicious clinical repurposing of psychotropic medications, criticized and panned, even though there are no approved drugs for 88.5% psychiatric diagnoses?1 Why allow insurers to refuse to pay for a medication that can help a patient, just because the patient has not been given the “official” diagnosis for which the FDA approved that drug?
And why doesn’t the FDA solve this problem by revising its requirements that registration trials for new medications test their efficacy for a single symptom, rather than a diagnosis comprising multiple symptoms?
Why do people not accept the fact that all drugs have benefits and risks, and that it is impossible to have pure efficacy without side effects? Why empower lawyers to make clinical care adversarial? Why do lawyers refrain from suing oncologists or manufacturers of life-saving chemotherapy drugs because of terrible adverse effects, but pounce on other medications that might cause a serious side effect in a tiny percentage of patients that is clearly spelled out in the package insert?
Why do people demonize the pharmaceutical industry far more than other industries? No other entity discovers and develops life-saving medications.
Why don’t people realize that, without medications, massive numbers of patients would be hospitalized and the death rate would rise? Why can’t people weigh risks and benefits of having a pharmaceutical industry, just as they assess the risk-benefit ratio of everything in life?
Should the government impose a massive ($1 or $2 trillion) tax hike to establish infrastructure for drug research and development, for the benefit of psychiatry and all other medical specialties?
Why is there a severe shortage of psychiatrists but a glut of lawyers? Why doesn’t society rationally deploy its resources to meet urgent social needs and priorities? And why do lawyers bill us for every minute we talk to them, while we field telephone calls and e-mail messages from patients without compensation?
Why did the FDA allow the pharmaceutical industry to develop direct-to-consumer advertising? Why do they not realize how that decision has complicated the doctor–patient relationship, and how it preempts physicians’ evidence-based decision-making by encouraging consumers to demand a drug that they saw on television—a contorted version of prescribing by proxy?
Why (speaking of prescribing without a license), do politicians pass laws allowing people who do not have required medical training to take a short-cut to becoming a prescriber? Why not mandate that politicians, and their families, receive medical care exclusively from unqualified practitioners on whom they bestow prescribing privileges without requisite comprehensive medical training?Why do some psychiatrists resist changing their practice patterns despite continuous advances that update the care they provide? Why do reports of exciting therapeutic breakthroughs, published in top-tier journals, go unread by so many practitioners? Why do they say they are too busy to read journals or peruse PubMed?
Why don’t people realize that today’s research is tomorrow’s treatment? That research is not a luxury but an ongoing necessity? Why don’t more freshly minted, young psychiatrists pursue a career in research to accelerate the pace of progress about the biological causes and treatments of serious psychiatric disorders? Why aren’t there more incentives to grow the next generation of psychiatric discoverers and Nobel laureates? Why don’t clinicians support research by referring patients to clinical trials of medications or to National Institutes of Health-funded investigations of the neurobiology of psychiatric disorders?
Are these just rhetorical questions?
Some might sound that way. But they are not. These questions are brewing inside the hearts and minds of many psychiatrists, although only a few seem determined to relentlessly seek answers on which medical science and society can act.
We should collectively pose these “why” questions and not accept long-winded, hollow answers. We need to foster the winds of change—not resign ourselves to winds in which answers blow about but, ultimately, disappear.

Why do lawyers refrain from suing oncologists or manufacturers of life-saving chemotherapy drugs because of terrible adverse effects, but pounce on other medications that might cause a serious side effect in a tiny percentage of patients that is clearly spelled out in the package insert?
Why do people demonize the pharmaceutical industry far more than other industries? No other entity discovers and develops life-saving medications.
Why don’t people realize that, without medications, massive numbers of patients would be hospitalized and the death rate would rise? Why can’t people weigh risks and benefits of having a pharmaceutical industry, just as they assess the risk-benefit ratio of everything in life?
Should the government impose a massive ($1 or $2 trillion) tax hike to establish infrastructure for drug research and development, for the benefit of psychiatry and all other medical specialties?
Why is there a severe shortage of psychiatrists but a glut of lawyers? Why doesn’t society rationally deploy its resources to meet urgent social needs and priorities? And why do lawyers bill us for every minute we talk to them, while we field telephone calls and e-mail messages from patients without compensation?
Why did the FDA allow the pharmaceutical industry to develop direct-to-consumer advertising? Why do they not realize how that decision has complicated the doctor–patient relationship, and how it preempts physicians’ evidence-based decision-making by encouraging consumers to demand a drug that they saw on television—a contorted version of prescribing by proxy?
Why (speaking of prescribing without a license), do politicians pass laws allowing people who do not have required medical training to take a short-cut to becoming a prescriber? Why not mandate that politicians, and their families, receive medical care exclusively from unqualified practitioners on whom they bestow prescribing privileges without requisite comprehensive medical training?Why do some psychiatrists resist changing their practice patterns despite continuous advances that update the care they provide? Why do reports of exciting therapeutic breakthroughs, published in top-tier journals, go unread by so many practitioners? Why do they say they are too busy to read journals or peruse PubMed?
Why don’t people realize that today’s research is tomorrow’s treatment? That research is not a luxury but an ongoing necessity? Why don’t more freshly minted, young psychiatrists pursue a career in research to accelerate the pace of progress about the biological causes and treatments of serious psychiatric disorders? Why aren’t there more incentives to grow the next generation of psychiatric discoverers and Nobel laureates? Why don’t clinicians support research by referring patients to clinical trials of medications or to National Institutes of Health-funded investigations of the neurobiology of psychiatric disorders?
Are these just rhetorical questions?
Some might sound that way. But they are not. These questions are brewing inside the hearts and minds of many psychiatrists, although only a few seem determined to relentlessly seek answers on which medical science and society can act.
We should collectively pose these “why” questions and not accept long-winded, hollow answers. We need to foster the winds of change—not resign ourselves to winds in which answers blow about but, ultimately, disappear.
