Insomnia – difficulty falling or staying asleep – was associated with a 69% greater risk of having a myocardial infarction than among adults without insomnia, according to new research.

Those who slept 5 or fewer hours per night had the highest risk for MI, and those with both diabetes and insomnia had double the risk for MI, compared with patients without these comorbidities.

The findings are from a meta-analysis of studies in more than 1 million patients, almost all without prior MI who were, on average, in their early 50s and followed for 9 years.

Yomna E. Dean, a medical student at Alexandria (Egypt) University, reported these results in a press briefing, and the study was simultaneously published in Clinical Cardiology. It will be presented at the upcoming at the annual scientific sessions of the American College of Cardiology.

“Insomnia and ]at least] 5 hours of sleep are highly associated with increased incidence of MI, an association comparable to that of other MI risk factors and as such, it should be considered as a risk factor for MI and to be incorporated into MI prevention guidelines,” the researchers concluded.

“We believe that [insomnia] should be screened and patients should be educated about the importance of sleep because nowadays insomnia is no longer a disease – sleep deprivation could also be a life choice,” Ms, Dean told a press conference prior to the meeting.

“Clinicians must educate the patients about the importance of sleep in maintaining a healthy heart and encourage proper sleep hygiene,” Ms. Dean reiterated in an email. “And if a patient still has insomnia, other methods should be considered such as cognitive-behavior[al] therapy for insomnia [CBT-I].”
 

Adds to growing evidence

This study does not allow any conclusion about whether treating insomnia will reduce heart attack risk, Jennifer L. Martin, PhD, president of the American Academy of Sleep Medicine, noted in a comment. Nor does it report the diversity of study participants, since insomnia is also a health equity issue, she noted, and insomnia symptoms and comorbidities were self-reported.

However, this analysis “adds to the growing evidence that poor quality or insufficient sleep is associated with poor health,” said Dr. Martin, professor of medicine at the University of California, Los Angeles, who was not involved with this research.

The study reinforces the recommendation from the American Heart Association, which includes “Get Healthy Sleep” as one of “Life’s Essential 8” for heart health, Dr. Martin noted.

“Particularly in primary care where disease prevention and health promotion are important, clinicians should be asking all patients about their sleep – just like they ask about diet and exercise – as a key aspect of maintaining heart health,” she said.

Advice about basic sleep hygiene advice is a first step, she noted.

When improved sleep hygiene is not enough to address chronic insomnia, the AASM’s clinical practice guidelines and the guidelines of the Department of Veterans Affairs/Department of Defense, recommend first-line treatment with CBT-I, typically offered by a sleep specialist or mental health clinician.

Similarly, the American College of Physicians suggests that sleeping pills should be reserved for short-term use in patients who may not benefit sufficiently from CBT-I.
 

Sleeping too little, too much, equally harmful

“Studies have found that insomnia and subsequent sleep deprivation puts the body under stress,” Ms. Dean said. “This triggers cortisol release which could accelerate atherosclerosis,” and increase risk of MI.

For this analysis, the researchers identified nine observational studies, published from 1998 to 2019, with data on incident MI in adults who had insomnia.

The diagnosis of insomnia was based on ICD diagnostic codes or on the DSM‐5, which defines insomnia as the presence of any of the following three symptoms: difficulty initiating sleep, difficulty maintaining sleep, or early morning awakening with inability to return to sleep. Patients with sleep apnea were excluded.

The studies were in populations in China, Germany, Norway, Taiwan, United Kingdom, and United States, in 1.1 million adults aged 18 and older. The patients had a mean age of 52 years and 13% had insomnia.

During follow-up, 2,406 of 153,881 patients with insomnia, and 12,398 of 1,030,375 patients without insomnia had an MI.

In the pooled analysis, patients with insomnia had a significantly increased risk of MI (relative risk, 1.69; P < .00001), after adjusting for age, gender, diabetes, hypertension, high cholesterol, and smoking.

Sleeping 5 hours or less was associated with a greater risk for MI than sleeping 6 hours, or 7-8 hours, but sleeping 9 hours or more was just as harmful.

Patients who had difficulty initiating and maintaining sleep – two symptoms of insomnia – had a 13% increased risk for MI compared with other patients (RR, 1.13; P = .003).

However, patients who had nonrestorative sleep and daytime dysfunction despite adequate sleep – which is common – did not have an increased risk of MI, compared with other patients (RR, 1.06; P = .46).

Women with insomnia had a 2.24-fold greater risk for MI than other women, whereas men with insomnia had a 2.03-fold greater risk for MI than other men.

Patients with insomnia had a greater risk for MI than those without insomnia in subgroups based on patients’ age (< 65 and > 65), follow up duration (≤ 5 years and > 5 years), and comorbidities (diabetes, hypertension, and hyperlipidemia).

The authors reported no relevant financial relationships.

Q2. Correct answer: A - No monitoring of PPI side effects. 

Rationale 

There are several putative risks associated with long-term PPI use: chronic kidney disease, dementia, vitamin and mineral deficiencies, and others. However, the overall quality of evidence to support these conclusions is low or very low, and the majority of the findings have low effect sizes that may be attributed to confounding. An American Gastroenterological Association clinical practice update recommended against routine monitoring for patients receiving long-term PPI treatment. However, data show that more than one-third of gastroenterologists still check for PPI side effects at least annually in their patients.

Q1. Correct answer: B - Adding calcium carbonate (antacid) to her current regimen  

Rationale 

Compared with proton pump inhibitors (PPIs), vonoprazan is a potassium-competitive acid blocker (PCAB), which inhibits acid secretion by competitively blocking availability of potassium to hydrogen-potassium ATPase. Vonoprazan is rapidly absorbed independent of eating and is not affected by CYP2C19 polymorphisms. Several studies have compared PPIs with vonoprazan. Although vonoprazan is highly effective for treating LA Grade A and B esophagitis, so is lansoprazole, and healing rates at 8 weeks are 100% versus 99.2%, respectively. In contrast, vonoprazan healing of LA Grade C and D esophagitis at 8 weeks is 98.7% compared with 87.5% for lansoprazole. 
Sleeping on pillows is not a reliable way to reduce reflux, as patients often move during sleep and lose any benefit from being propped on them. Antacids would not provide superior acid inhibition, compared with vonoprazan, and avoiding spicy foods would not address the underlying permissive reflux barrier that exists (hiatal hernia).

There is a potential risk of early structural valve deterioration with the Abbott Trifecta valve and Trifecta valve with glide technology (Trifecta GT), the U.S. Food and Drug Administration says in a letter to health care professionals posted on its website.  

Evidence in the literature suggests a higher cumulative incidence of early structural valve deterioration (SVD) and a lower freedom from reintervention due to SVD with the Trifecta valves, compared with other commercially available bovine pericardial valves, the FDA says.

The Trifecta and Trifecta GT valves are heart valve replacement devices intended to treat diseased, damaged, or malfunctioning native or prosthetic aortic heart valves, the letter notes. The first-generation Trifecta valve was approved in 2011 but is no longer marketed in the United States. The Trifecta GT valve was approved in 2016.

Medical device reports (MDRs) received by the FDA describe early SVD with Trifecta valves, with a peak time to SVD of 3 to 4 years post-implant. “Reported outcomes include surgical valve explant/replacement, transcatheter valve-in-valve intervention, and in some cases death,” the FDA notes.

In a letter to customers, Abbott says a “complaint analysis has shown that most cases of early SVD which occur within 5 years post-implant are characterized as a non-calcific leaflet tear, while most cases of late SVD which occur beyond 5 years post-implant are characterized as a fibrous-calcific SVD.” 

The FDA recommends that health care providers take the following actions:

• Be aware of the potential risk of early SVD with Trifecta valves, and current patient management considerations, as communicated by Abbott.
• Discuss the risks and benefits of all available aortic valve treatment options with patients and caregivers as part of shared clinical decision-making prior to surgery.
• Read and carefully follow the Instructions for Use when implanting a Trifecta GT valve.
• Monitor patients who have undergone implantation with Trifecta valves for signs and symptoms of potential SVD.
• Instruct patients to seek medical attention with new onset of symptoms such as shortness of breath or fatigue.
• Ensure lifelong follow-up visits, conducted at least yearly, including transthoracic echocardiogram assessment of the valve beginning 1-year post-implant.

The FDA is working with Abbott to further evaluate the issue and develop additional patient management strategies, if needed. The FDA says it will continue to monitor the literature and reports of adverse events related to the issue.

Clinicians are encouraged to report any adverse events or quality problems with the Trifecta valves to their local Abbott representative or the customer service department at 1-800-544-1664.

Health care professionals can also report adverse reactions or quality problems they experience using these devices to the FDA’s MedWatch program.

SAN DIEGO – Epstein-Barr Virus (EBV) infection is widely recognized as a contributor to risk of multiple sclerosis (MS). Although most adults have been exposed, it is very rare to find MS in an individual with no prior EBV exposure.

That apparent relationship has driven interest in a vaccine against EBV in an effort to reduce MS incidence on a population level.

At a session at the annual meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS), two researchers debated the potential benefits and pitfalls of such a program. The issues included the possible benefit in MS and other EBV-related conditions such as mononucleosis and various cancers, and whether EBV infection is a sufficient cause for MS, as well as concerns about vaccinating a healthy at-risk population.
 

Reducing the risk of MS by targeting EBV

Jeffrey I. Cohen, MD, spoke first, and cited several lines of evidence supporting the importance of EBV in MS. One study showed a 32-fold increased risk of MS following primary infection with EBV, and another showed that higher EBV nuclear antigen (EBNA) antibody titers were associated with a 36-fold higher risk of MS. “So we have two completely independent studies suggesting that EBV is really very important as a cofactor for development of MS,” said Dr. Cohen, chief of the laboratory of infectious diseases and chief of the medical virology section at the National Institutes of Health, Bethesda, Md.

EBV is also latent in B cells, and anti-B cell therapy is an effective therapeutic strategy for MS. However, the mechanism remains unknown.

Targeting EBV could involve attacking infected cells, or a therapeutic vaccine could be employed to treat EVB-infected individuals, similar to the shingles vaccine. “In all of these methods, one would end up with fewer EBV infected B cells and as a result, presumably you’d have reduced antigenic stimulation of EBV-infected B cells to stimulate either antibodies or T cells that could damage the nervous system. By reducing this, one might be able to [treat] multiple sclerosis,” said Dr. Cohen.

He did acknowledge concerns. It isn’t yet understood whether destroying EBV-infected cells would actually improve outcomes. It also may be more difficult to reduce a latent infection than to prevent infection, since almost all B cells become latently infected. “Thus we think perhaps a role for preventing infection or modifying the initial infection could be important,” said Dr. Cohen.

The most advanced vaccine candidate is a soluble form of EBV glycoprotein gp 350, which is the dominant glycoprotein on the surface of the virus and infected cells. It reduced the risk of mononucleosis by 78%, but it did not prevent EBV infection. There were no safety concerns. Two more vaccines are currently in clinical trials – an mRNA vaccine against a gp 350 sponsored by Moderna, and a gp 350 nanoparticle vaccine by the NIH.

Dr. Cohen acknowledged that safety is the most important factor, since it would be given to healthy individuals, and probably children. There are worries that a vaccine using EBV proteins could worsen MS. In particular, higher titers of antibodies against EBNA have been linked to developing MS and the anti-EBNA antibody has been implicated in molecular mimicry related to MS. However, the current vaccines avoid EBNA. Another worry is that a vaccine could delay onset of disease to an older age, when infection might be more dangerous. However, no delay in onset has been noted with the varicella vaccine or polio vaccines, which prompted similar concerns.

Vaccinating against EBV could also reduce other conditions such as mononucleosis and several cancers.
 

Does EBV infection even matter?

In his talk, Peter Calabresi, MD, made the case that EBV is not the sole cause of MS, and thus targeting it may prove ineffective. Dr. Calabresi is director of the division of neuroimmunology at Johns Hopkins Medicine, Baltimore.

Why was he asked to provide a rebuttal? “About this time last year, I commented at a meeting that we should be thoughtful as we think about what to do about EBV and MS. I do believe that constructive dialogue is the foundation of science,” he said. He also stated that he is not opposed to vaccines. “I congratulate Dr. Cohen on all of his vaccine successes,” he said.

SAN DIEGO – Epstein-Barr Virus (EBV) infection is widely recognized as a contributor to risk of multiple sclerosis (MS). Although most adults have been exposed, it is very rare to find MS in an individual with no prior EBV exposure.

That apparent relationship has driven interest in a vaccine against EBV in an effort to reduce MS incidence on a population level.

At a session at the annual meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS), two researchers debated the potential benefits and pitfalls of such a program. The issues included the possible benefit in MS and other EBV-related conditions such as mononucleosis and various cancers, and whether EBV infection is a sufficient cause for MS, as well as concerns about vaccinating a healthy at-risk population.
 

Reducing the risk of MS by targeting EBV

Jeffrey I. Cohen, MD, spoke first, and cited several lines of evidence supporting the importance of EBV in MS. One study showed a 32-fold increased risk of MS following primary infection with EBV, and another showed that higher EBV nuclear antigen (EBNA) antibody titers were associated with a 36-fold higher risk of MS. “So we have two completely independent studies suggesting that EBV is really very important as a cofactor for development of MS,” said Dr. Cohen, chief of the laboratory of infectious diseases and chief of the medical virology section at the National Institutes of Health, Bethesda, Md.

Fewer than 10% of American adults with type 2 diabetes who qualified for treatment with newer agents – such as an SGLT2 inhibitor or GLP-1 agonist – actually received treatment with at least one drug from drug class in 2017-2020, based on a new analysis of just over a thousand adults who participated in a representative, biannual survey and self-reported a diabetes diagnosis.

The cost of these agents, and their uncertain cost-effectiveness at current prices, is likely a key driver of the low usage rate, say the authors of a brief report published in Annals of Internal Medicine.

“Clinical studies have shown that both GLP-1 [glucagonlike peptide–1] receptor agonists and SGLT2 [sodium-glucose cotransporter 2] inhibitors yield additional clinical benefits, compared with older treatments in reducing body weight and progression of cardiovascular disease and chronic kidney disease,” write Shichao Tang, PhD, from the U.S. Centers for Disease Control and Prevention, Atlanta, and colleagues.

“However, these medications come at a substantially higher cost,” they stress.

Dr. Tang explained in an interview that the new study “points to prior studies about the high cost of these medications as a potential barrier to use, but more research is needed to understand cost-effectiveness and any potential barriers to use, including cost.”

The work “did not include research into cost-effectiveness or why the percentage of people already using these medications was low,” he emphasized.

Dr. Tang and colleagues used data collected by the U.S. National Health and Nutrition Examination Survey during two 2-year cycles between 2017 and 2020 that included 1,417 people who self-identified a diagnosis of diabetes.

Excluding those who likely had type 1 diabetes and those with incomplete data left 1,330 survey participants, including 1,133 (85%) who fit criteria for the treatment of type 2 diabetes with an agent from one of the two studied classes, as recommended in 2022 by a panel representing the American Diabetes Association and the European Association for the Study of Diabetes.

Among these 1,133 people – who represent more than 22 million American adults with type 2 diabetes who fit the 2022 criteria – a scant 3.7% were actually taking a GLP-1 agonist and 5.3% were taking an SGLT2 inhibitor.

“While it’s important to note that our data predate the 2022 recommendations, these drugs were offered as second-line therapy for patients with certain diabetes-related complications in 2017-2020” and hence provide potentially useful insights, noted Dr. Tang, a health economist with the CDC National Center for Chronic Disease Prevention and Health Promotion.

Based on retail prices listed on a United States–based website, a 30-day supply of an oral SGLT2 inhibitor can cost about $550-$600 per month, while common subcutaneously injected GLP-1 receptor agonists can run from a few hundred dollars for a daily injection or close to $1,000 for a formulation administered weekly.

“Cost-effectiveness was not formally considered in the current guideline, but an assessment of cost-effectiveness may assist better targeting of interventions to achieve the greatest effect at a sustainable cost,” the researchers conclude.

The study received no commercial funding. None of the authors had relevant financial relationships.

Spinal muscular atrophy (SMA) is a hereditary neuromuscular disease that typically begins in infancy or childhood but can manifest at any age. 

It is characterized by the irreversible and progressive degeneration of motor neurons in the spinal cord and brainstem. This results in a wide range of symptoms, in addition to which there is substantial variation in the rate of progression and disease prognosis. 

Although early diagnosis and timely therapy can slow or prevent disease progression, disease-modifying therapies since 2016 have significantly advanced the management of SMA. 

In a clinically focused program, Dr Perry Shieh, a neuromuscular neurologist from the University of California, Los Angeles, discusses the three medications currently approved by the US Food and Drug Administration: nusinersen, risdiplam, and onasemnogene abeparvovec. 

He weighs the clinical benefits and key considerations for the use of each drug and emphasizes the need for shared decision-making with the patient.

The often-delayed diagnosis of isolated nail psoriasis (NP), along with the possibility of a “reciprocal relationship” with psoriatic arthritis, “should serve as an impetus for dermatologists to improve their diagnostic accuracy,” investigators said in a research letter.

Diagnosis of isolated NP was delayed by almost 3 years among the 87 cases recorded and “arthritis was most often diagnosed concurrently with NP,” at a major nail referral center between Jan. 1, 2001, and Dec. 21, 2022, Michelle J. Chang of Drexel University, Philadelphia, and associates reported.

In what the authors say is, “the largest study documenting clinical and histologic features in patients with isolated NP,” the two most common clinical features were onycholysis and nail plate pitting, seen in 79% and 70% of cases, respectively. No other single feature had a prevalence higher than 28%.

The most frequent clinical dyad was onycholysis and pitting in 66% of patients, followed by onycholysis/nail thickening in 33% and onycholysis/splinter hemorrhage in 32%. The most common histologic features were parakeratosis in 79% and neutrophil infiltration in 48%, the investigators said.

Psoriatic arthritis (PsA), a focus of the study, occurred in 10 (11%) of the 87 individuals with isolated NP. Considering this finding, and “the close proximity between the nail apparatus and joint, we hypothesize a reciprocal relationship, with nail unit inflammation precipitating PsA,” Ms. Chang and associates wrote.

Senior author, Shari Lipner, MD, PhD, of the department of dermatology, Weill Cornell Medicine, New York, is a consultant for Ortho-Dermatologics, Hoth Therapeutics, and BelleTorus. Ms. Chang and the two other investigators had no conflicts of interest to declare.

Mantle cell lymphoma (MCL) is an aggressive form of non-Hodgkin lymphoma characterized by the proliferation of CD5-positive B cells within the mantle zone that surrounds normal germinal center follicles. MCL is a rare disease that most commonly presents in adult men (male to female ratio > 2:1) in the fifth and sixth decades of life. Individuals diagnosed with MCL typically present with constitutional symptoms, such as weight loss, night sweats, persistent fever, and fatigue. Approximately 25% of cases present with extranodal involvement with the bone marrow; peripheral blood and gastrointestinal tract are most often involved. In patients with extensive node involvement in the gastrointestinal tract, additional symptoms at presentation often include abdominal pain, abdominal fullness, and bloating. Skin involvement in MCL is rare and usually indicates widespread disease. 

According to the guidelines of the World Health Organization–European Organization for Research and Treatment of Cancer, a diagnosis of MCL is established on the basis of the morphologic examination findings and immunophenotyping. 

Immunohistochemically, expression of cyclin D1 in normal lymphoid cells is very low and often undetectable; only hairy cell leukemia shows moderate expression of cyclin D1. Therefore, positive immunohistochemistry for cyclin D1 is pathognomonic for MCL. Increased expression of cyclin D1 protein leads to dysregulation of the cell cycle and stimulates uncontrolled cell proliferation. It is also indirect evidence of the chromosomal translocation (11;14)(q13;q32) on the CCND1 gene, which is detected in 95% of cases of MCL. In addition, negative expression of antigens may also help to differentiate MCL from other lymphomas. MCL does not usually express the antigens that are associated with germinal centers, such as CD10, CD23, and BCL6. Thus, these antigens can be used to distinguish MCL from B-cell lymphomas of germinal center origin, including follicular lymphoma, Burkitt lymphoma, and diffuse large B-cell lymphoma.

The National Comprehensive Cancer Network recommends chemotherapy followed by radiation for stage I or II disease. In general, patients with advanced-stage disease benefit from systemic chemotherapy. Because MCL is clinically heterogeneous, treatment may require adjustment on the basis of the patient's age, underlying comorbidities, and underlying MCL biology such as TP53 mutations. During induction therapy, prophylaxis and monitoring for tumor lysis syndrome is strongly recommended to be considered. Before treatment, hepatitis B virus testing is recommended because of an increased risk for viral reactivation with use of immunotherapy regimens for treatment.

In addition, negative expression of antigens may also help to differentiate MCL from other lymphomas. MCL does not usually express the antigens that are associated with germinal centers, such as CD10, CD23, and BCL6. Thus, these antigens can be used to distinguish MCL from B-cell lymphomas of germinal center origin, including follicular lymphoma, Burkitt lymphoma, and diffuse large B-cell lymphoma.

The National Comprehensive Cancer Network recommends chemotherapy followed by radiation for stage I or II disease. In general, patients with advanced-stage disease benefit from systemic chemotherapy. Because MCL is clinically heterogeneous, treatment may require adjustment on the basis of the patient's age, underlying comorbidities, and underlying MCL biology such as TP53 mutations. During induction therapy, prophylaxis and monitoring for tumor lysis syndrome is strongly recommended to be considered. Before treatment, hepatitis B virus testing is recommended because of an increased risk for viral reactivation with use of immunotherapy regimens for treatment.

Mantle cell lymphoma (MCL) is an aggressive form of non-Hodgkin lymphoma characterized by the proliferation of CD5-positive B cells within the mantle zone that surrounds normal germinal center follicles. MCL is a rare disease that most commonly presents in adult men (male to female ratio > 2:1) in the fifth and sixth decades of life. Individuals diagnosed with MCL typically present with constitutional symptoms, such as weight loss, night sweats, persistent fever, and fatigue. Approximately 25% of cases present with extranodal involvement with the bone marrow; peripheral blood and gastrointestinal tract are most often involved. In patients with extensive node involvement in the gastrointestinal tract, additional symptoms at presentation often include abdominal pain, abdominal fullness, and bloating. Skin involvement in MCL is rare and usually indicates widespread disease. 

According to the guidelines of the World Health Organization–European Organization for Research and Treatment of Cancer, a diagnosis of MCL is established on the basis of the morphologic examination findings and immunophenotyping. 

Immunohistochemically, expression of cyclin D1 in normal lymphoid cells is very low and often undetectable; only hairy cell leukemia shows moderate expression of cyclin D1. Therefore, positive immunohistochemistry for cyclin D1 is pathognomonic for MCL. Increased expression of cyclin D1 protein leads to dysregulation of the cell cycle and stimulates uncontrolled cell proliferation. It is also indirect evidence of the chromosomal translocation (11;14)(q13;q32) on the CCND1 gene, which is detected in 95% of cases of MCL. In addition, negative expression of antigens may also help to differentiate MCL from other lymphomas.

A scoop shave biopsy was performed, including at least a 1-mm margin of normal-looking skin. Pathology was consistent with melanoma in situ.

Melanoma in situ, also called Stage 0 melanoma, is defined by atypical melanocytes that have not begun to invade the dermis and, therefore, have a Breslow thickness of 0 mm. While invasive melanoma is responsible for the largest number of skin cancer deaths in the United States (estimated to be 7990 in 2023), melanoma in situ maintains a very high cure rate when treated appropriately.¹

Dermoscopy can help differentiate melanoma from benign nevi or other benign skin lesions. In this case, dermoscopy revealed a fine pigment network at the periphery that indicated this lesion was made up of melanocytes. There were also atypical vascular markings (the milky red color) in the center. Taken together, these findings were strongly indicative of melanoma.

Standard of care for melanoma in situ is a wide local excision with a margin of 5 to 10 mm. Melanoma in situ does not require sentinel lymph node biopsy. However, a lymph node biopsy would have been necessary if the melanoma had been ≥ 1 mm in thickness or if it had been ≥ 0.8 mm in thickness with higher-risk features, such as an increased number of mitoses per high-power field on pathology. Mohs micrographic surgery (MMS) is emerging as an alternative method to wide local excision to treat melanoma in situ. However, it can only be done in specialized centers that can do rapid immunohistochemical staining on frozen sections. MMS is especially useful in cosmetically sensitive areas of the body and in areas where the true size of the melanoma in situ is unclear.

This patient subsequently underwent a wide local excision in the office with a margin of 6 mm. A sentinel lymph node biopsy was not performed. The patient will continue with skin surveillance consisting of full skin exams 3 to 4 times in the first year of diagnosis, then twice annually for Years 2 to 5. He will then come in for annual skin exams after that.
