CLINICAL TOOLS

Abstract: The Choosing Wisely Canada (CWC) initiative is a partner in a global effort to increase the efficiency and effectiveness of medical care by stimulating conversations between patients and care givers about the benefits and risks of commonly done tests and treatments. One of the earliest and broadly publicized recommendations was to stop routine lumbar spine imaging in the absence of clinical red flags. The rationale for discouraging this practice, including the quantification of associated harm, is not as widely known. The CWC initiative includes "Toolkits" for a number of clinical conditions, which extend the conversation beyond what should be avoided to include recommendations for appropriate care. The Alberta CWC partners have developed a Toolkit for low back pain for use by individual clinicians, physician groups, and at the systems level.
Key Words: Low back pain, imaging, overuse, red flags.

In the absence of red flags and/or significant chronicity don't order x-rays or advanced imaging for low back pain.
Be cautious about attributing any findings from imaging as the "cause" of low back pain in a particular patient; recognize normal age related changes.
Low back imaging is required in the presence of clinical Red Flags for which invasive intervention is planned. Clinical correlation of the images is mandatory.
The indications for specific interventional treatments either surgical or image guided must be determined by history and physical examination.
Most low back pain patients need treating, not testing.
Patients presenting with low back pain are often anxious and worried that they may have a serious underlying anatomical cause. This anxiety is not relieved by discussions of abnormalities found on routine imaging.
Patients respond to a treatment plan that is supported by pertinent handouts and clear explanations including discussions about when imaging could be considered and when a referral might be the correct course.
Treatment for low back pain should not be delayed until the cause has been "established" by investigation; appropriate treatment can be determined by the history and physical examination and supported by the anticipated positive clinical response.
A successful back school educates the patient about the benign nature of back pain and provides the tools to transfer knowledge about back hygiene into practice in the patient's life.

CLINICAL TOOLS

Abstract: Cercarial dermatitis (swimmers' itch) consists of urticarial papules that form when the larvae of avian parasitic flatworms penetrate the skin. Cercarial dermatitis is common in the summer months where heaviest recreational swimming occurs, and when the temperature is ideal for amplified schistosome development.
Key Words: cercarial dermatitis (swimmers' itch), non-communicable, water-borne disease.
Cercarial dermatitis usually occurs with exposure to fresh water, but can occur with shallow salt water exposure as well.
The eruption typically occurs on uncovered skin 12-24 hours (up to 8 days) after exposure.
The eruption is self-limited, lasting 4-10 days (up to 20 days).

Treating Patients as Real People, Not a Collection of Symptoms

No applauses yet

When you enter a car showroom, a salesperson may identify you as a small-car buyer or a second-hand car buyer, or, if you're known to the dealership, perhaps as a solid every-three-year leaser. With a label in mind, the salesperson will approach you in a particular way. The same can be said of the barista who knows which customer is a "decaf latte" and who is a "dark roast with two creams"—or, in my case at my local Tim Hortons, a medium with two milks in a refill, often with a "good morning" that includes my name. (It's only at the drive-thru window does anything beyond my coffee preference enter the conversation, because I know some of the other servers and will ask them how they're doing in school.)

It's not uncommon to see the same dynamic in medicine—perhaps less so in emergency rooms or ambulatory clinics, but especially on medical wards where one begins what could become an ongoing relationship between physician and patient.

It's understandable that physicians and nurses are primarily concerned with the medical conditions they're responsible for treating. We develop languages that help us identify these conditions, and our shorthand often turns a person with an illness and personal worries and concerns into an organ system with deficiencies that require repair. It's easy to understand the dynamic that leads to the old-fashioned and much-criticized characterization of "the gallbladder in room 203."
So how does one get around the pressure to focus on the illness affecting a person rather than the person who happens to have an illness?

Part of the answer might lie in the long training of health-care providers, when a focus on the humanities should supersede, for a substantial period of time, the focus on what is in essence the scientific underpinning of medicine. Along those lines, I have read a definition of medicine that resonates with me. To paraphrase, it says medicine is a human, interactive and dedicated profession that's informed by science. In some ways, this contrasts with more standard understandings of medicine as the science of preventing, curing and treating diseases.

Whichever approach one takes, it's important to never forget Emily Dickinson's poem about surgeons: "Surgeons must be very careful, when they take the knife! Underneath their fine incisions, stirs the Culprit—Life! "

Another key reason why the patient's identity is so important is that it strongly affects how and why they may respond to medical interventions and the people providing their care.

As well, individual stories of lives lived make medicine a most wonderful profession. The multiple stories are part of the woven and sometimes miraculous fabric of this healing profession.

The dictum I use when teaching medical trainees dealing with a patient who is unknown to them, which I have found works wonders (other than in extreme situations when no time can be spent on anything other than immediate medical intervention), is to start an interview with, "So who are you?" rather than the usual "How are you?" This allows the often-surprised patient to tell the physician a bit about their life and values through their own personal narrative.

It can also cement the personal relationship between patient and doctor (and family, when they're part of the initial discussion). After adequate time is taken to develop a personal rapport, the business of "medical science" can take place on a platform of personal identity and valued personhood.

It's vital to good medical care.

CLINICAL TOOLS

Abstract: Acne vulgaris is a common skin condition encountered in family practice and can cause significant distress during adolescence. Treatment options discussed include topical benzyl peroxide, topical retinoids, oral and topical antibiotics, hormonal therapy, and isotretinoin. The following review article provides up-to-date recommendations for treating mild to severe pediatric acne.
Key Words: acne vulgaris, adolescence, treatment, pathogenesis.
The differential diagnosis for acne in adolescence includes corticosteroid induced acne, folliculitis, keratosis pilaris, papular sarcoidosis, perioral dermatitis, pseudofolliculitis barbae, and tinea faceie.
Acne may be classified as mild, moderate or severe based on the number and type of lesions involved as well as the total surface area involved.
Acne therapy is targeted at treating as many pathogenic factors as possible.
Topical fixed-dose combination therapies can be used for all types and severities of acne in children 9 years of age and older.
Both topical and oral antibiotics work by inhibiting P acnes protein synthesis and decreasing inflammation.
Do not be afraid of isotretinoin. It can be used first line in patients with severe nodular and/or inflammatory acne, acne conglobata, and recalcitrant acne.12 It is the only treatment that targets all four pathogenic factors implicated in acne vulgaris and can permanently decrease acne.

Five Things to Know about Cauda Equina Syndrome

Teaser: 

Drew A. Bednar, MDCM, FRCS(C), FAAOS,

Clinical Professor of Orthopedic Surgery, Adult Spine Surgeon, McMaster University, Hamilton, ON.

CLINICAL TOOLS

Abstract: Cauda Equina Syndrome (CES) is a rare progressive syndrome of pain and neurological deficits below the waist caused by massive central lumbar disc prolapse. The most common clinical presentation is highly variable with multifocal mixed polyradicular deficits. Loss of bladder and/or bowel control can be subtle and is frequently not the patient' chief complaint. These symptoms must be aggressively sought by the assessing physician. While delays of a few hours in the diagnosis and management may not be deleterious, definitive lumbar MRI imaging and (if positive) surgical care referral are emergent.
Key Words: Cauda Equina Syndrome; Presentation; Diagnosis; Outcome.

The CES patient often presents with rapidly escalating, poorly controlled pain. There may be daily or even more frequent physician visits.
While standing, the CES patient commonly adopts a "sciatic scoliosis": forward bending at the waist and leaning to either side as they attempt to decompress themselves. They may limp or need walking aids. These features help distinguish them from drug-seekers or malingerers.
Since patients are distracted by extreme pain, they may not reliably volunteer a history of bladder/bowel disturbance.
Cauda Equina Syndrome is an acute or subacute pathology caused specifically by massive central prolapse of a lumbar disc. Decompensation lumbar spinal stenosis is not Cauda Equina Syndrome.
Cauda Equina Syndrome most commonly presents with complaints of back or leg pain. These differ from common sciatica in being rapidly progressive, difficult to control with analgesics and often associated with considerable locomotor impairment.
The neurological examination in Cauda Equina Syndrome most commonly finds a mixed pattern of incomplete polyradicular deficits in the distribution of multiple lumbar and sacral nerve roots involving either of the legs and/or the saddle (perineum). The classically described complete flaccidity with loss of all motor control from the waist down is extremely rare.
Patients presenting with CES will not commonly volunteer complaints of incontinence or urinary retention as they are often overwhelmed by the magnitude of their pain. The assessor must specifically ask about bowel/bladder function and when indicated, test these by bladder scanning or catheterizing and a digital rectal examination.
As a rapidly evolving syndrome of neurological deterioration, CES warrants emergent imaging investigation and referral. Although the literature is not precise on the critical time point, it is widely accepted that patients should receive surgical intervention within 24 to 48 hours.
