Newsline NURSE practitioners (NPs) and physician assistants (PAs) can autonomously substitute for elderly care physicians (ECPs) in a nursing home setting because of the high level of collaborative care they provide, according to a study published in BMJ Open. Researchers in the Netherlands selected 7 nursing homes in which NPs (n=3), PAs (n=2), and registered nurses (RNs; n=2) were compared with ECPs (n=15) and medical doctors (MDs; n=2). Data collected consisted of observations of the NP/ PA/RN and an ECP/MD;interviews with the participants; questionnaires filled out by the NP/PA/RN, ECPs/MDs, and managing directors/managers of the facility; and analysis of internal policy documents. The clinicians worked in 3 types of units: unit for residents with physical disabilities, dementia special care unit, and geriatric rehabilitation unit. Autonomous substitution for ECPs was present in 4 of the facilities; in 2 cases, the professional was a PA, and the professional was an NP in 2 cases.

In 3 of the cases, 2 PAs and 1 NP worked on their own unit or units with an ECP in the background as an expert colleague rather than a supervisor; in 1 case, the NP and the ECP shared responsibility for residents on a unit and worked together closely. Factors that made substitution successful were organizational factors that acknowledge NPs and PAs as independent clinicians, as well as individual factors such as the proactivity of the clinician. In facilities 3, 4, and 7, the collaboration between the NP, PA, and ECP was based on trust. The ECP shared responsibilities with the NP or PA, and the clinicians all shared the same views on what constituted good resident care, which was established through the use of ad hoc meetings. In certain cases, however, the ECP did not trust the NP or PA, and responsibilities of care were not equally shared. In all cases, the professionals performed tasks such as the structural evaluation of restraints, writing care programs, enhancing

rehabilitation climate by implementing a breakfast or lunch buffet, educating the care team, and being a member of working groups who discussed specific themes and innovations such as fall prevention. “Our description of three mechanisms of substitution showed that according to participants, the NPs and PAs are able to deliver similar quality of healthcare as the ECPs, based on the condition that the collaboration between the NP or PAs and the ECP is qualified as successful,” the authors concluded.

Hawaii Legislation Repeals Physician Chart Reviews for Practicing PAs HAWAII GOVERNOR David Ige signed the SB 1406 bill on July 2, 2019, which repealed the state’s outdated requirement for 100% chart review by a physician and included other changes to physician assistant (PA) laws currently in place in Hawaii. “Repealing 100% chart review for all PAs within seven days is a huge administrative burden that we’re happy to finally have removed from our state laws,” said Christina Starks, PA-C, president of the Hawaii Academy of PAs. Additional changes implemented in the legislation include allowing chart review to be determined at the practice level

for PAs with >1 year of experience. For PAs with <1 year of experience, 50% chart review should be conducted for the first 6 months and 25% for the second 6 months. A “group of physicians” are among the individuals who may establish a work relationship with a PA. Although the 100% chart review requirement was repealed, the requirement for 100% chart co-signature for all controlled substance prescriptions remains in effect under the Uniform Controlled Substances Act of Hawaii. The bill went into effect on July 1, 2019. ■

Chronic Pancreatitis: Challenging to Diagnose, Difficult to Treat Chronic pancreatitis stems from a variety of pathogenic entities that result in chronic inflammation, fibrosis, and irreversible damage to the pancreas.

C

hronic pancreatitis (CP) is a debilitating disease that is associated with approximately $150 million in healthcare expense annually.1 It is a complicated disease in that it is multifactorial, problematic to diagnose, and difficult to treat. The majority of patients with CP experience severe abdominal pain; 50% will develop endocrine insufficiency, and 80% will develop exocrine insufficiency within 5 years of diagnosis. Abdominal pain and other myriad symptoms lead to significant psychosocial and physical disability and reduced quality of life.2

Etiology

Diagnostic imaging for chronic pancreatitis often begins with abdominal CT.

12 THE CLINICAL ADVISOR • SEPTEMBER 2019 • www.ClinicalAdvisor.com

A variety of pathogenic entities contribute to CP, all of which result in chronic inflammation, fibrosis, and irreversible damage to the pancreas. These etiologies can be remembered according to the mnemonic TIGAR-O: toxicmetabolic, idiopathic, genetic, autoimmune, recurrent, and obstructive.3 Toxic-metabolic triggers include chronic alcohol abuse, tobacco use, hypercalcemia, hyperlipidemia, uremia, and others. Chronic exposure to toxins is responsible for oxidative damage at the cellular level, resulting in parenchymal destruction and reduced pancreatic function.4 Idiopathic CP occurs in 2 patterns based on age: idiopathic chronic juvenile pancreatitis in the pediatric population (early onset) and idiopathic senile chronic pancreatitis in the elderly (late onset).5 One form of early-onset CP is tropical


CP, also known as fibrocalculous pancreatic diabetes; this entity is most common in tropical, southern India.1 The bimodal age distribution in idiopathic CP is poorly understood, but environmental, genetic, and autoimmune factors are likely responsible. To relegate a case of CP as idiopathic requires that all other entities be excluded.4 Genetic causes of CP are the result of mutations primarily involving “premature activation of trypsinogen or failure to inactivate trypsin during pancreatic inflammation,” which ultimately damages the pancreas.5 Trypsin is the active form of the precursor enzyme trypsinogen. Trypsinogen is produced by and stored in the pancreas, and upon stimulation by cholecystokinin, it is released into the duodenum where it is converted to trypsin, an enzyme involved in the breakdown of protein. If this chain of events fails, trypsin promotes autodigestion of acinar tissue, leading to pancreatitis. Genes directly or indirectly related to the trypsin pathway and underlying derangements in the development of CP include: CFTR (codes for cystic fibrosis transmembrane regulator protein), PRSS1 (codes for cationic trypsinogen enzyme), SPINK1 (codes for pancreatic secretory trypsin inhibitor protein), CTRC (codes for chymotrypsin C enzyme), and CASR (codes for calcium sensing receptor protein).3,5 Autoimmune pancreatitis occurs in 2 patterns. Type 1 correlates with deposition of immunoglobulin G4 (IgG4) in pancreatic tissue, leading to subsequent damage to the pancreas. Infiltration of IgG4, however, is not confined to the pancreas; IgG4 may invade the bile duct, salivary glands, retroperitoneum, kidneys, and lymph nodes.5 Type 2, in contrast, is characterized by cellular infiltration of neutrophils, which damage the pancreatic ducts. Both types 1 and 2 respond to treatment with steroids.5 Recurrent pancreatitis is typified by repeated episodes of acute pancreatitis, resulting in cumulative tissue damage. Complete morphologic resolution rarely occurs following numerous attacks. Deposition of collagen and formation of scar tissue interfere with restoration of glandular structure and function, resulting in CP.4 Obstructive CP consists of segmental anatomic blockade in the ductal system by occlusive stones, tumors, or structural entities such as pancreas divisum. Obstruction of enzyme flux in and out of the ductal network results in accumulation of digestive enzymes within the pancreas.This dynamic process creates elevated intraductal and parenchymal pressures, mimicking a compartment syndrome and resulting in ischemic tissue damage.4,6 Clinical Presentation

Because many patients with CP display risk factors associated with certain etiologies, it is important that social and medical

histories be explored for conditions predisposing patients to the disease.7 The most common symptom of CP is epigastric pain, often exacerbated by lying down and alleviated by leaning forward. Radiation to the back also occurs frequently. Pain is typically postprandial, and can be persistent or intermittent. Depending on disease severity, patients may also present with exocrine dysfunction, which manifests as malabsorption (weight loss, diarrhea, and steatorrhea), and endocrine disturbance presenting as hyperglycemia. Signs and symptoms vary depending on the etiology of CP.7 Physical examination in CP often reveals midline epigastric tenderness. Rigidity and rebound are rare. The presence of ascites suggests a pseudocyst, abscess, or other complication. Physical findings may prove beneficial in ruling out conditions that mimic CP (Table).7 No single laboratory test is diagnostic of CP. Amylase and lipase are usually normal in chronic disease but may be elevated in early disease stages or during an acute exacerbation. In late-stage CP, amylase and lipase may be low, signaling exocrine insufficiency, although this is not sensitive or specific.3,7 Laboratory data are of further value in determining precise etiologies of CP, especially metabolic toxins, and in monitoring disease flares or complications. For example, elevated liver enzymes may suggest alcohol abuse. Azotemia may indicate uremic pancreatitis. Hypercalcemia may indicate calcium deposition in the pancreas.Abnormal blood glucose levels are associated with loss of endocrine function. Elevated white blood cell counts may indicate pancreatic infection or necrosis.7 Diagnostic Testing

Clinical presentation, radiologic imaging, and pancreatic function testing (PFT) are pillars of investigation for the diagnosis of CP, which is a complex illness that often eludes diagnostic certainty. Radiologic modalities are helpful for Continues on page 19

CHRONIC PANCREATITIS

Pancreatic function testing is useful for diagnosing chronic pancreatitis based on quantification of exocrine pancreatic insufficiency. visualizing the pancreas and associated calcifications, which is a common radiologic finding in CP. Imaging is often the first step in diagnostic testing. Noninvasive modalities include computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP). More invasive tools, such as endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS), are helpful in the evaluation of more challenging cases.3 Computed Tomography Diagnostic testing often begins with abdominal CT with pancreatic protocol. CT images are effective for detecting scattered pancreatic calcifications, which is suggestive of late-stage CP. CT is also useful in assessing for disease complications, such as pseudocysts and necrosis, and for differentiating similar diagnoses such as pancreatic adenocarcinoma, cholangiocarcinoma, and other biliary tract pathology. Lack of sensitivity in earlier stages of CP, however, limits the capability of CT to visualize ductal and parenchymal derangements.3 Magnetic Resonance Imaging MRI is additive in diagnosing CP. According to the American Pancreatic Association, MRI is more sensitive than CT in the evaluation of CP in earlier stages, conferring an important advantage for early clinical intervention and enhanced disease outcomes. Although several MRI protocols are available, the MRCP/secretin protocol is regarded as the most accurate.3 MRCP involves an MRI of the abdomen focused on structural images of the pancreas, bile duct, and gallbladder. This method provides more definitive visualization than MRI of the abdomen alone.3 The MRCP/secretin protocol involves intravenous administration of secretin, a hormone that stimulates pancreatic exocrine secretion. Images are generated during secretin administration to qualify pancreatic function while also visualizing pancreatic structure. Furthermore, secretin administration increases the sensitivity and specificity of MRCP.3

criteria are more sensitive, whereas Rosemont criteria are more specific.8 Regardless of the criteria used, EUS remains a useful test. Diagnosis should be established based on signs and symptoms consistent with CP in combination with EUS or other imaging modality.5 Pancreatic Function Testing PFT is useful in diagnosing CP based on quantification of exocrine insufficiency.3 Methodology of PFT may involve either direct or indirect approaches. Direct PFT involves administration of secretin followed by endoscopic collection of stimulated pancreatic secretions while obtaining simultaneous EUS imaging. Direct PFT is distinct from the MRCP/ secretin protocol in that it provides quantitative physiologic assessment. In contrast, MRCP/secretin testing is a qualitative evaluation of exocrine insufficiency wherein no fluid is collected or measured. Since direct PFT is invasive, it is rarely employed today. Indirect PFT is far more commonly performed and involves the assessment of fecal elastase 1 or fecal fat concentrations in a stool specimen. Fecal elastase 1 is a pancreatic enzyme that digests protein and aids in transport of cholesterol.3 Fecal elastase 1 concentrations <200 μg/g of stool are abnormal and indicative of some degree of exocrine insufficiency. Fecal elastase 1 concentrations <100 μg/g of stool indicate severe exocrine insufficiency and are supportive of a diagnosis of CP. Moreover, this assessment

Endoscopic Ultrasound EUS is regarded as the most sensitive imaging tool for the diagnosis of CP and identification of ductal and parenchymal abnormalities early in the disease.8 EUS provides a high sensitivity of 91% depending on which diagnostic criteria are employed, conventional or Rosemont.5,8 The limitation of EUS, however, is low specificity. Yet as with sensitivity, specificity relies on the set of criteria employed.5,8 Conventional

Abdominal pain, malabsorption, weight loss, and steatorrhea are indicative of exocrine pancreatic insufficiency. requires only 1 stool sample and is not affected by pancreatic enzyme replacement therapy (PERT).3,5,9 Fecal fat measurements are less specific but still may be considered. Detection of ≥7 g of fat per 24 hours during a 72-hour collection period is abnormal and suggestive of a diagnosis of CP.3,5,9 When interpreting indirect PFTs, confounding elements such as diarrhea and bacterial overgrowth can cause false positives. Likewise, the presence of acute pancreatitis can cause false negatives. Celiac disease and inflammatory bowel disease must be considered in the interpretation of PFTs.3 Endoscopic Retrograde Cholangiopancreatography ERCP is intended primarily for therapeutic purposes and is rarely used for diagnosis of CP. When selected for diagnosis, ERCP allows for performance of diagnostic biopsies. ERCP is invasive and carries significant risk for triggering acute pancreatitis.Additional limitations include visualization restricted to the ductal system, intraoperator bias, and lack of specificity.3 Histology obtained by ERCP lacks sensitivity and specificity due to sampling error.5 Treatment

Initial treatment for CP is lifestyle modification with alcohol and smoking cessation, along with elimination of other metabolic or exogenous toxins. Further treatment is divided into 3 categories: medical, endoscopic, and surgical. Appropriate selection of therapeutic measures depends on the overall health of the patient, as well as the etiology and severity of CP.5 Medical Pain control is the established mainstay of treatment, yet pain management is one of medicine’s most elusive therapeutic measures. In the past, mechanical dysfunction due to pancreatic duct obstruction and resultant ductal hypertension was thought to be responsible for most of the pain associated with CP. More recently, however, neurobiologic mechanisms have been implicated. In theory, recurrent damage to the pancreas results in inflammation of intrapancreatic nerves triggering abnormal pain as organized in the central nervous system.5,6 Concepts based on nerve inflammation support inclusion of neuropathic pain medications to existing treatment regimens. Such novel regimens could prove beneficial in pain control as well as in reduction of opioid use and dependence. Patients with CP are often responsive to medications such as tricyclic antidepressants, gabapentin, pregabalin, and selective serotonin reuptake inhibitors.Therapeutic success with

such regimens lends biologic plausibility to the concept of pancreatic neuropathy.5,6 Some patients, in contrast, achieve adequate pain relief with nonsteroidal anti-inflammatory drugs and acetaminophen.Antioxidant therapy and pancreatic enzyme replacement are available but are of unpredictable efficacy in reducing pain.5 Another medical essential is management of pancreatic exocrine dysfunction. Abdominal pain, malabsorption, weight loss, and steatorrhea are indicative of exocrine insufficiency. Treatment is advisable for patients with these signs and symptoms. Most patients begin therapy with digestive enzyme replacement such as 40,000 units of lipase with meals. Severe insufficiency may require up to 90,000 units 3 times daily. Lesser amounts are appropriate for lighter meals or snacks.5,9 Typical enzyme preparations contain amylase and protease. Histamine-2 receptor antagonists and proton pump inhibitors provide benefit in addition to enzyme supplementation. These agents act by minimizing premature enzymatic breakdown of pancreatic enzymes by stomach acid. Reduction of fat intake and consumption of multiple small meals throughout the day are also effective for some patients. Response to enzyme replacement can be monitored by frequently checking serum levels of fat-soluble vitamins, especially vitamin D.9 A third goal of medical therapy is management of pancreatic endocrine deficiency. Labelled as “pancreatic diabetes,” or “type 3C diabetes,” this entity must be distinguished from type 1 or type 2 diabetes mellitus, although it is treated similarly in early stages.5,9,10 Until insulin is necessary for euglycemia, type 3C diabetes may be successfully treated with metformin. In addition to antidiabetic effects, metformin has antineoplastic properties and has been reported to reduce the risk of pancreatic cancer by as much as 70%.10 Sulfonylurea preparations may also be considered an appropriate choice, but care must be taken to avoid hypoglycemia. If endocrine insufficiency ensues and first-line management is ineffective, insulin will be necessary.5,10 Incretin-based therapies, such as glucagon-like peptide-1 (GLP-1) analogues and dipeptidyl peptidase 4 (DPP-4) inhibitors, are not recommended due to concomitant increased risk of medication-induced pancreatitis and problematic side effects. Likewise, thiazolidinediones should be avoided.10 Endoscopy Endoscopy may be necessary when medical therapy fails. Careful patient selection is prudent to avoid endoscopic

Surgery Interventional surgery is reserved for patients for whom medical and endoscopic therapies are unsuccessful. Certain cases of severe CP require surgery as first-line therapy. Surgical indications include poor pain control; duodenal, biliary, and pancreatic duct obstruction; symptomatic pseudocysts (complex or large); extensive necrosis; and suspicion of pancreatic cancer.5 Four common surgical techniques are used: • Pancreaticojejunostomy, for obstructive ductal disease, can be performed using the Frey or Puestow techniques.5 • Pancreaticoduodenectomy, for cases with significant disease of the pancreatic head, can be performed using the Whipple or Beger approaches.5 • Distal pancreatectomy is preferred for disease in the pancreatic tail.5 • Total pancreatectomy with islet auto-transplantation can be performed in patients with nonobstructive disease and atrophy of the acini involving the entire pancreas.5

Early recognition of CP is paramount to preserving quality of life for patients with the condition. ■


FEATURE: SALARY SURVEY

Are you being fairly compensated? As Clinical Advisor continues to be a champion for the nurse practitioner (NP) and physician assistant (PA) audiences, we recognize that just as clinical practice has evolved over the past year, so too has compensation. Are you considering a career in a new location or specialty and unsure about how this change may affect your compensation? The results of the 2019 NP/PA Salary Survey are in and available to help guide your next big career move. Similar to the results from previous surveys, more than half of all NPs and PAs who responded to the survey reported earning more in 2018-2019 than in the prior year.

See how your salary compares with those of your peers as reported in the 2019 NP/PA SALARY SURVEY

NPs and PAs reported average annual salaries in the 2019 survey of $107,973 and $115,881, respectively.

Although the wage gap persists between male and female advanced practice providers, it has narrowed in 2019. In 2018, men earned approximately $17,000 more than their female counterparts. In contrast, results from the 2019 salary survey indicate that male NPs earned approximately $11,000 more than female NPs, and male PAs earned approximately $15,000 more than female PAs.

The West Coast remains the region with the highest average yearly compensation, with NPs earning $117,311 and PAs earning $125,307. The majority of NPs surveyed reported practicing in suburban locations (38%); however, those practicing in urban locations (36.8%) earned the highest salary. Like NPs, the majority of PAs surveyed practiced in suburban locations (42.2%), but PAs working in rural areas earned the highest salary ($118,344). Interestingly, family medicine is no longer the specialty in which the majority of NPs and PAs are employed (27% and 13.8%, respectively). Like last year, most NP and PA respondents practice in a stand-alone clinic, but those working in hospitals reported earning the highest salary ($122,598 and $127,173, respectively). Additionally, 40.5% of NPs and 41.1% of PAs report working in more than 1 location, and approximately one-fourth of respondents see 51-75 patients per week. The majority of NPs and PAs anticipate earning as much or more than they currently earn in the year to come, with more than half of all clinician respondents expecting more money in their paychecks in 2020.

Dermatology Clinic CASE #1

Alopecia Areata

Alopecia areata is a prevalent autoimmune disease of the hair follicles leading to nonscarring hair loss, commonly presenting as smooth patches of welldefined hair loss on the scalp. It has been frequently described in the literature since the early 20th century, with numerous studies investigating its etiology and treatment. A variety of presentations have been seen, ranging from small patches of hair loss to total body hair loss, and response to treatment has been found to vary widely among patients. After androgenetic alopecia, alopecia areata is the second most common cause of hair loss, affecting an estimated 4.5 million people in the United States, with a worldwide prevalence of 0.1% to 0.2% and an estimated lifetime incidence of 2.1%.1-3 Although it is often seen in children and younger adults, individuals of all ages can be affected with the condition.3 There is no apparent sex predominance, no significant variance among ethnicities, and hair of all colors can be affected.3,4 Alopecia areata is believed to occur as a result of an autoimmune process directed against follicular melanocytes or matrix keratinocytes in which inflammatory cells attack hair follicles in the anagen phase and prematurely propel them into the catagen phase.5 As the hair shaft can then no longer be anchored within the hair canal, it is subsequently shed, leading to visible hair loss.6 Given its underlying autoimmune basis, patients with alopecia areata are at increased risk for other conditions including atopy, vitiligo, thyroid disease, and other autoimmune diseases, as well as depression and anxiety.3,7 Alopecia areata has a strong genetic component, with a family history increasing the risk of developing the condition.7 Likewise, a family history of other autoimmune conditions increases the risk of developing alopecia areata. Patients with Down syndrome have also been found to be at increased risk for alopecia areata.7 The diagnosis of alopecia areata is primarily made clinically, with the classic presentation of well-defined, smooth patches of nonscarring hair loss and absence of any notable epidermal changes.8 Although the skin in the observed patch is typically normal, peachy or mildly reddened discoloration can sometimes be seen. Hair loss most commonly involves the scalp, but other areas such as the eyebrows, eyelashes, beard, extremities, or anywhere else on the body may be affected.4

Patches can be single, multiple, or diffuse, and classification of alopecia areata is typically based on this designation. Alopecia areata can present as patchy alopecia; alopecia totalis, where hair loss involves the entire head; or alopecia universalis, where hair loss involves the whole body.4,8 The latter two of these diagnoses are commonly observed to have high resistance to treatment.9 Other commonly observed patterns include ophiasis type, which is a band-like hair loss of the parieto-temporo-occipital scalp, or ophiasis inversus (sisaipho), which involves hair loss of the fronto-parietotemporal scalp.8 Common clinical findings in alopecia areata can include “exclamation mark hairs,” which are short hairs that taper closer to the skin, and nail pitting, an associated clinical finding observed in two-thirds of cases.4 Upon histologic examination, alopecia areata typically involves an infiltrate of lymphocytes surrounding the hair bulb, sometimes described as a “swarm of bees.”5 This finding may be absent in older alopecia areata lesions; therefore, other clues such as eosinophils, melanin and lymphocytes in fibrous tract remnants, and an increase in catagen-telogen follicles may help in diagnosis.5

Patches of alopecia areata can be single, multiple, or diffuse, and classification is typically based on this designation. The differential diagnosis for alopecia areata includes a variety of hair loss conditions, most notably tinea capitis, trichotillomania, and telogen effluvium.4,8 Several clinical features of these conditions can help differentiate them from alopecia areata. The presence of inflammation and scale as well as postauricular lymphadenopathy can help identify tinea capitis. The finding of hairs broken off at different lengths is more consistent with trichotillomania. Diffuse hair loss as opposed to localized hair loss can help distinguish telogen effluvium. Other potential diagnoses to consider include lupus or secondary syphilis, both of which can be confirmed via serologic testing.8 Although alopecia areata can be treated, no definitive cure is known. Spontaneous remission occurs in approximately 8% to 68% of cases, with the higher remission rates occurring when <25% of the scalp is involved.10 Treatment can often help with hair regrowth and prevent further hair loss.10 Initial treatment may involve topical or intralesional corticosteroids, with the former often preferred for pediatric patients who may not tolerate injections.10 Minoxidil foam or solution is

30 THE CLINICAL ADVISOR • SEPTEMBER 2019 • www.ClinicalAdvisor.com


sometimes added as adjuvant therapy. Short, 6-week courses of oral corticosteroids can also be effective for hair regrowth; however, the risk of relapse is high, and long-term use is not advised given the associated side effects. Other treatments including methotrexate and topical immunotherapy, such as diphenylcyclopropenone and squaric acid dibutylester, may be considered in refractory cases.9 New therapies including Janus kinase inhibitors such as tofacitinib, ruxolitinib, and baricitinib are currently under investigation.10 With continued development and study of new treatment options for alopecia areata, it is hoped that more effective hair regrowth and sustained disease control will be attainable. Our patient was treated with intralesional triamcinolone acetonide (5 mg/mL × 1 cc). At his return visit 6 weeks later, he was noted to have significant hair regrowth and was happy with the results.

Tinea Versicolor

Tinea versicolor, also known as pityriasis versicolor, is a benign, chronic discoloration of the skin caused by the proliferation of yeast. Malassezia furfur, previously known as Pityrosporum, is the dimorphic, lipophilic fungus that causes tinea versicolor.1 In 1853, Robin described the first Malassezia species.2,3 M furfur is a normal component of the skin flora that may opportunistically convert from the yeast to the mycelial form that invades the stratum corneum in tinea versicolor.4 Tinea versicolor occurs more frequently in hot, humid areas and tends to affect the skin of the face, arms, chest, and back. Adolescents and young adults are most commonly affected. Tinea versicolor is primarily a cosmetic concern but when pruritic can affect quality of life.2,5 Although the etiology of tinea versicolor appears to be multifactorial, genetics may predispose some individuals to developing these skin lesions. Adolescents and young adults more frequently develop tinea versicolor because increased sex hormones stimulate sebum production. In contrast, children less frequently experience tinea versicolor; when they do, it is more commonly

found on the face. Other suspected contributing factors include the application of oils, creams, and cosmetics, which provide lipid nourishment for Malassezia. Tinea versicolor is associated with hyperhidrosis, exposure to sunlight, and oral contraceptive use, but it is not linked to poor hygiene.1,5 Immunocompromised individuals are at higher risk for the condition.4 Tinea versicolor typically presents as well-demarcated, hypopigmented, hyperpigmented, or salmon-colored patches, commonly on the back and chest. The lesions differ widely in color, hence the term “versicolor.”1 Oftentimes, a single herald patch precedes the development of multiple smaller lesions that may coalesce into larger patches. Upon scraping, a fine scale is visible, and some patients complain of mild pruritus.1,2,6 The diagnosis of tinea versicolor is made clinically but can be confirmed with a potassium hydroxide (KOH) mount of scrapings.

A skin biopsy of tinea versicolor is characterized by lymphocytes around the dermal vasculature, mild epidermal hyperkeratosis, and acanthosis; however, it is rarely required to confirm diagnosis.4,5 Differential diagnoses of tinea versicolor include psoriasis, seborrheic dermatitis, pityriasis rosea, mycosis fungoides, secondary syphilis, pityriasis alba, erythrasma, and vitiligo. Seborrheic dermatitis tends to present with a thicker scale, usually on the scalp and face. Results from the KOH

After treatment with 2% ketoconazole shampoo, the patient started to notice resolution of the rash. The discoloration completely faded within a few weeks. ■ Emily K.

Vitiligo presents with completely depigmented macules and patches as opposed to hypopigmented lesions. Erythrasma will fluoresce coral-red on Wood lamp illumination rather than the characteristic yellow-green of tinea versicolor.1,4,5 Treatment of tinea versicolor with topical and oral antifungals is usually successful. Topical antifungals, such as ketoconazole, are first-line therapy due to their targeted activity against Malassezia. Selenium sulfide and zinc pyrithione shampoos act by removing the stratum corneum and are also effective with a shorter required duration of therapy than ketoconazole antifungals.2 One to 3 applications of 2% ketoconazole can be sufficient for treatment.7 Topical treatment is less expensive than systemic treatment; however, application to the back may be difficult for some patients, and topical antifungal shampoos must be applied for extended periods of time before rinsing. Oral therapies are indicated for patients for whom topical therapy is ineffective or those who experience recurrent or widespread tinea versicolor. Oral fluconazole can safely treat extensive or recurrent tinea versicolor. Drug interactions and liver function abnormalities have been reported with the use of oral antifungals.8 Patients using either oral or topical therapies should be advised that the scale quickly resolves after treatment of active infection but dyschromic areas may persist for months. The successful resolution of active infection can be confirmed by KOH examination. Patients who experience multiple recurrences

Psoriasis

Psoriasis is a chronic, immunemediated disease with a variety of subtypes affecting the skin and joints.1 Prior to the first clinical description by Robert William in 1808, the disease was commonly confused with leprosy.2 Psoriasis affects approximately 2% of people worldwide, with an equal prevalence among men and women.3,4 The disease primarily affects adults in a bimodal distribution, with peaks in diagnoses for patients in their 20s and 50s.4 Although the etiology of psoriasis is not fully understood, immune system overactivation along with genetic and environmental factors have been found to contribute to disease development. Psoriasis is an autoimmune disease historically thought to be predominantly caused by CD4+ helper T cells. More recent research indicates that cell type Th17 secretes the proinflammatory cytokines that cause the inflammation and keratinocyte proliferation associated with the disease. Development of Th17 is maintained in a positive feedback loop by interleukin (IL)-23 produced by dendritic cells of the innate immune system.5 Genetic factors are implicated in the pathogenesis of psoriasis, as 30% of affected individuals have a first-degree relative with the condition.6 Genetic influences are also demonstrated by a concordance rate of approximately 70% in monozygotic twins and 20% in dizygotic twins. Multiple genes including PSORS1, CARD14, and IL36RN have been linked to psoriasis.7 In addition, environmental factors such as medications, smoking, alcohol, obesity, and stress contribute to disease development in genetically susceptible individuals.8 The diagnosis of psoriasis is primarily made clinically. Classic findings include relapsing and remitting, well-demarcated, erythematous plaques with dry, silvery scales.1,9 Other common features are scalp involvement and nail discoloration, pitting, and dystrophy. Plaque psoriasis, also known as psoriasis vulgaris, is the most common subtype, comprising 90% of diagnoses. Lesions can be present on the extensor, periumbilical, and perianal regions in adults, while smaller plaques occurring on the face and flexural regions are seen in children.6 Guttate psoriasis, most commonly seen in children after a recent streptococcal infection, is characterized by small droplet-shaped plaques in a centripetal distribution. While guttate psoriasis accounts for only 2% of all cases, approximately one-third of affected patients will develop plaque psoriasis later on. Another rare form of psoriasis is pustular psoriasis, which is

characterized by a localized eruption of white pustules following steroid withdrawal.1 Early diagnosis and treatment are important to prevent disease progression. Assessment tools, such as The Psoriasis Area and Severity Index (PASI) score, are used following diagnosis to determine disease severity based on the extent of involvement. Because 30% of patients develop psoriatic arthritis as a complication, physicians should assess for joint symptoms at each visit.9 Screening for mental disorders, such as depression and anxiety, is crucial due to the impact of the disease on a patientâ&#x20AC;&#x2122;s psychological well-being.10 Although biopsy is rarely required for diagnosis, histologic features can distinguish psoriasis from other conditions when

The differential diagnosis of psoriasis includes eczema, tinea capitis, tinea corporis, and seborrheic dermatitis. the diagnosis is unclear. Epidermal changes involve acanthosis, hyperkeratosis, and parakeratosis with thickened rete ridges that form the characteristic plaques. Engorged blood vessels causing erythema are visualized in the tips of the dermal papillae. An inflammatory infiltrate composed of T cells, macrophages, neutrophils, and mast cells is present within the epidermis and dermis.9 The differential diagnosis of psoriasis includes eczema, tinea capitis, tinea corporis, and seborrheic dermatitis.9 Psoriasis can be differentiated from eczema primarily by distribution on the extensor surfaces; the classic appearance of erythematous plaques with dry, silvery scales; and presentation at an older age. The Auspitz sign, seen when bleeding occurs after removal of a silver plaque, and the Koebner phenomenon, observed when psoriatic lesions occur in areas of trauma, make psoriasis a more likely diagnosis over other dermatologic conditions.6 Other diagnoses to consider include lichen planus, pityriasis rosea, secondary syphilis, and cutaneous lymphoma.9 While lichen planus presents as violet papules on the wrists, psoriasis presents as silvery plaques on the extensor surfaces. A negative rapid plasma reagin favors a diagnosis of psoriasis over secondary syphilis. The treatment of psoriasis involves topical medications, phototherapy, and systemic agents. First-line therapy for mild cases often includes topical glucocorticoids, vitamin D analogues, or both. While glucocorticoids provide effective and rapid relief of symptoms, they can lead to skin atrophy with long-term use.9,11 In areas where steroid treatment is often avoided, such as the face and intertriginous areas,

Dermatologic Look-Alikes topical calcineurin inhibitors may be effective. Although less effective, vitamin D agents are safest for the long-term topical treatment of psoriasis. Phototherapy with ultraviolet (UV) B light can also be used for the short-term treatment of moderate to severe forms of psoriasis due to the suppressive effect of UV exposure on the Th17 immune response.8,9 However, phototherapy must be used with caution due to the risks of premature aging and skin cancer. Systemic agents such as methotrexate, cyclosporine, and acitretin are usually reserved for more severe cases of psoriasis due to the risk of organ toxicities.9,11 Methotrexate is highly effective at treating severe psoriasis and psoriatic arthritis but must be used with caution due to the risk of liver cirrhosis.11 Within recent years, several new biologic therapies have been introduced that target the inflammatory pathways with intermediate effect on the pathogenesis of psoriasis.9 Tumor necrosis factor-α inhibitors, such as etanercept and infliximab, treat psoriasis by blocking proinflammatory cytokines.11 Ustekinumab inhibits IL-12 and IL-23, thus preventing the development of Th17 lymphocytes.9 These agents pose a risk for infections and malignancies due to their immunosuppressive effects. Recent understanding of the molecular mechanisms involved in psoriasis has also enabled the development of newer agents.11 The patient in this case was diagnosed with psoriasis and started on methotrexate and topical corticosteroids. He had a partial response and was eventually transitioned to adalimumab (a tumor necrosis factor-α inhibitor) that led to complete clearance of the psoriasis.

CASE #2

Eczema

Eczema, or atopic dermatitis, is a chronic inflammatory disorder characterized by intense itching and recurrent skin lesions. Derived from the word atopy, meaning “a propensity for allergic disease,” the term atopic dermatitis was first introduced by Fred Wise and Marion Sulzberger in 1933.12 The incidence of eczema has increased more than 3-fold since the 1960s, for reasons that are largely unknown.13 Unlike psoriasis, eczema is a disease of childhood, affecting 10% to 20% of children but only 1% to 3% of adults worldwide.13 Ninety percent of eczema cases appear in the first 5 years of life. Recent evidence reveals a higher incidence of eczema

in developed countries and a higher vulnerability in people moving to more industrialized areas.14 Eczema is characterized by elevated levels of immunoglobulin E (IgE) in response to environmental antigens, triggering an inflammatory response in the skin.While the causes of eczema are multifactorial, 2 main hypotheses have been proposed to describe the pathophysiology of the disease. The first hypothesis argues that eczema is caused by an imbalance of type-2 helper T (Th2) cells, causing an overabundance of IL-4, IL-5, and IL-13 that leads to an overproduction of IgE.15 The second hypothesis describes mutations in the filaggrin gene (FLG) that encodes a protein involved in the permeability barrier of the stratum corneum. These mutations increase the skin’s permeability to allergens and microbes, triggering a Th2mediated inflammatory response that leads to the typical presentation of eczema.16

Eczema, or atopic dermatitis, is a chronic inflammatory disorder characterized by intense itching and recurrent skin lesions. Risk factors for eczema include genetic, socioeconomic, and environmental influences. Genetic factors are strongly associated with the development of atopic dermatitis, with a concordance rate of approximately 75% in monozygotic twins and only 30% in dizygotic twins. Furthermore, FLG mutations are found in 50% of patients with atopic dermatitis.15 Socioeconomic and environmental risk factors also play a role in the development of eczema, as suggested by the higher incidence of the disease in industrialized countries.14 Environmental factors positively correlated with eczema include colder climates, increased fast-food intake, obesity, pollution, and tobacco smoke. Protective factors include exposure to UV light, consuming fresh fruits, and breastfeeding. Many studies propose a “hygiene hypothesis” of eczema, which posits that a decrease in exposure to microbes in childhood increases susceptibility to allergic diseases. Environmental factors that increase exposure to microbial agents early in life, such as attendance in daycare and exposure to dogs, are considered protective.17 Eczema classically presents as a relapsing dermatitis characterized by intense pruritus and eczematous lesions.18 Acute lesions of eczema are described as erythematous patches with vesicles, oozing, and crusting. Lichenification, excoriations, papules, and nodules are more common in chronic forms of the disease.15 Infantile lesions frequently involve the face, scalp, and extensor surfaces whereas adults and children more

commonly experience flexural involvement.18 Associated disorders include asthma and allergic rhinitis. The diagnosis of eczema requires 3 of the following major diagnostic criteria: pruritus, relapsing course, typical distribution, family or personal history of atopy, and onset at age <2 years.18 Several other minor criteria have been described and include xerosis, white dermatographism, Dennie-Morgan lines, elevated levels of IgE, immediate skin test reactivity, and food intolerance.16 Approximately half of patients with eczema present with allergic sensitivities and elevated IgE levels.15 The differential diagnosis of eczema varies according to the age at presentation. In infants, many primary immunodeficiency diseases present with elevated IgE levels and an eczematous rash similar to eczema. Examples include hyper-IgE syndrome, DOCK8 deficiency, PGM3 deficiency, WiskottAldrich syndrome, IPEX syndrome, and Netherton syndrome. Particular characteristics, such as eczematous rashes occurring immediately following birth, favor these diagnoses over atopic dermatitis.When patients present with eczematous rashes after age 5 years, malignancies such as cutaneous T-cell lymphoma should be included in the differential. Contact dermatitis, nutritional deficiencies, scabies, seborrheic dermatitis, drug eruptions, and psoriasis are other diagnoses to consider.18 The key features that distinguish eczema from other syndromes include infantile onset, intense pruritus, xerosis, age-dependent distribution, and a fluctuating course.19 Although there is no cure for eczema, spontaneous remission occurs prior to adolescence in approximately 75% of

patients.15 Treatment of eczema involves hydration, elimination of aggravating factors, and pharmacologic therapy. First, hydration in the form of emollients should be applied cutaneously to improve the skin’s barrier function and reduce the need for steroid treatment. Patients should also be educated on the avoidance of known aggravating factors, such as irritating soaps, products containing perfumes, and wool. Pharmacologic therapy includes both topical and systemic medications, with the latter reserved for refractory cases.13 Topical glucocorticoids serve as the first-line pharmacologic treatment of eczema and are used both for the treatment of flares and as maintenance therapy.15 Topical calcineurin inhibitors, such as tacrolimus, prevent the production of cytokines from Th2 cells. Antimicrobial agents can be effective in certain cases, as dermatologic infections are associated with eczema and often aggravate the disease.13 Phototherapy can be considered for treatment-resistant cases but can cause premature aging of the skin and increase the risk for skin cancer.15 Systemic immunosuppressants such as cyclosporine, glucocorticoids, methotrexate, mycophenolate, and azathioprine are reserved for patients with severe or refractory eczema due to the risk of side effects.13 An increased understanding of eczema in recent years has led to the development of monoclonal antibodies targeting specific cytokines involved in the pathogenesis of the condition, such as IL-4, IL-13, IL-22, and IL-31. These biologic agents have the potential to decrease the frequency of flares-ups for those with eczema, offering a promising outlook for those affected.20

Medical Errors and Negligence A series of medical errors and negligence in a nursing home lead to an elderly man’s death. BY ANN W. LATNER, JD

This month we look at a case involving several errors that led to the death of a patient.The case went to trial and resulted in a verdict for the plaintiff that included punitive damages.The defendants appealed, and the Court of Appeals was asked to decide whether punitive damages were appropriate. The patient, Mr K, experienced a stroke in his mid-80s that resulted in memory problems and the inability to manage his own medications or walk without assistance. Mr K had diabetes for which he took insulin. After 2 years of caring for Mr K at home with the help of nurses, his family decided that he needed more supervised care than they could provide. When Mr K was aged 87 years, he was moved into The Pines, a facility that provided memory care. The facility did not request a physician’s medical assessment or admission order prior to admitting Mr K. The patient had been treated at a VA hospital previously, and there was some confusion as to who his primary care physician was. Mr K’s family provided a list of his medications, which included insulin glargine and insulin aspart. However, the facility had difficulty verifying the

list as no primary physician was identified. The facility assigned one of its contracted physicians to be Mr K’s attending physician. Due to the confusion regarding his medication regimen, Mr K’s son stayed with him at the facility the first night to monitor his blood sugar levels and administer his medications. The next morning, Mr K’s son checked the patient’s blood glucose, gave him his medication, and took him to a scheduled appointment at the VA hospital. Upon returning to The Pines, Mr K’s son checked his father’s blood sugar levels again and administered his medication. He then left his father in The Pines’ dining room for lunch. After lunch, Nurse B checked the patient’s blood sugar level, which showed elevated readings of 358 mg/dL and 398 mg/dL. Concerned, she called Nurse Practitioner (NP) A, who worked with the physician who had been assigned to Mr K. Cases presented are based on actual occurrences. Names of participants and details have been changed. Cases are informational only; no specific legal advice is intended. Persons pictured are not the actual individuals mentioned in the article.

LEGAL ADVISOR Neither NP A nor the physician had seen Mr K, yet NP A gave a medication order over the phone, changing Mr K’s regimen. She discontinued the insulin glargine and insulin aspart, and instead ordered metformin and insulin detemir twice daily.The new medication regimen meant that the patient went from receiving 10 units of insulin daily to 55 units daily. The facility notified Mr K’s family that the brand of insulin had changed, but the family was not told about the addition of metformin or that the insulin dosage had been changed. Mr K began experiencing episodes of hypoglycemia on the new regimen. Two days after the medication change, Nurse B found Mr K’s blood sugar level to be 51 mg/dL. She did not contact the assigned physician or NP A; instead, she gave Mr K orange juice. When that failed to increase his glucose level,

To protect against liability, never order or change medications for a patient you have not evaluated in person. she administered oral glucose. After the glucose was given, Mr K’s blood sugar level rose to 186 mg/dL. At 2:00 AM the following morning, Nurse B found Mr K incoherent. She noted that verbal stimuli and a sternum rub elicited no response, and he had pinpoint pupils. According to Nurse B’s notes, Mr K’s blood sugar level was 52 mg/dL at that time. She wrote in the chart,“Oral glucose gel was given.After 10 minutes, retook finger stick. Blood sugar was 48. After waiting 5 minutes, remeasured blood sugar, 28.” Nurse B called for an ambulance. Upon arrival, emergency medical technicians administered glucose intravenously. Mr K died at the hospital the next day. Mr K’s family sued the facility, the company that provided the contracted physicians and NPs, and several others. The case went to trial before a jury who decided in favor of Mr K’s family and awarded a small amount of compensatory damages (approximately $5,000) as well as $100,000 in punitive damages. The facility appealed. Legal Background

Because the facility specifically appealed the punitive damages, the Court of Appeals had to decide whether punitive damages were warranted. The facility argued that the award of $100,000 was excessive and in violation of the Due Process Clause of the 14th Amendment. Three criteria are used to examine the appropriateness of the amount of punitive damages: 1) the degree of reprehensibility of the defendants’

conduct; 2) the disparity between the harm suffered and the amount of punitive damages; and 3) the difference between the punitive damages and civil penalties authorized in comparable cases. The facility only argued the first criteria and claimed that its actions did not rise to the level of reprehensible. The Court of Appeals disagreed and pointed out that Mr K had been admitted without a physician’s medical assessment or order, without an accurate verified medication list, and without knowing who his primary physician was. A drastic medication change was made within 24 hours of his arrival without an examination performed by a physician or NP. The Court also pointed out that according to Nurse B’s notes, Mr K was given oral glucose gel, which should never be administered to unconscious patients.The Court noted that expert testimony pointed out numerous missed opportunities by the facility to notice and correct the drastic overmedication of the patient, as well as the failure of Nurse B to notify the physician or NP about the incidents of hypoglycemia. The facility had promised a level of care that it was neither able nor licensed to provide. The family had been paying $6000 per month for memory care, but the facility was only licensed as a personal care home, requiring much lower levels of skilled care under the state’s regulations. The experts also faulted the nurses and staff at the facility for not recognizing that increasing a patient’s insulin from 10 units to more than 50 units should raise a red flag. Finally, the experts faulted Nurse B for giving an unresponsive patient a gel form of glucose when she should have given the patient glucagon, which is administered via injection. The Court of Appeals held that the egregious conduct of the facility, even for the brief time the patient was there, supported the amount of punitive damages and affirmed the award. Because of the patient’s age at his death, his frail health, and his minimal economic prospects, the compensatory damages were low as the economic “value” of a person is often tied to their age. Protecting Yourself

To protect against liability, never order or change medications for a patient you have not evaluated in person. This should be obvious, particularly in this case where NP A didn’t have any medical records on the patient. If you encounter a situation where you do not have access to a patient’s medical records, you must conduct your own examination and work-up. It is never acceptable to treat a patient based simply on a family member’s verbal report of the patient’s medical history and medication regimen. ■ Ms Latner, a former criminal defense attorney, is a freelance medical writer in Port Washington, New York.
