CLINICAL TOOLS

Abstract: Obstructive Sleep Apnea (OSA), where patients stop breathing numerous times during sleep, is a disorder linked to serious medical, socioeconomic, and psychological morbidity, yet most patients with OSA remain undetected. Physicians should consider symptoms of frequent/loud snoring, complaints of daytime sleepiness or fatigue, high blood pressure and obesity or excessive body fat distribution in the neck or upper chest area as possible indications of untreated OSA.
Key Words: obstructive sleep apnea, screening, management.
Untreated OSA is associated with significant morbidity and mortality and results in increased healthcare utilization.
OSA is more prevalent in individuals with a chronic medical illness.
Almost 90% of individuals with OSA remain undiagnosed.
Treatment of OSA improves medical outcome; this is particularly relevant in medically ill patients.
Evidence-based medicine supports screening for OSA as part of routine clinical care.
Newer technology allows doctors to 'skip the waiting line' and obtain quick and accurate sleep testing for their patients.

Choosing Wisely Canada and Low Back Imaging: The view from Alberta

Teaser: 

Dr. Ted Findlay, D.O., CCFP,

is a Clinical Assistant Professor in the Department of Medicine at the University of Calgary and he is on the Medical Staff at Alberta Health Services, Calgary Zone in Calgary, Alberta.

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.

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).

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.

Pre-test CME Quiz Post-test CME Quiz
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.

Abstract: Back education or “Back Schools” are used both as a method of prevention and, in conjunction with traditional rehabilitation and exercise programs, as a component in treatment of recurrent or persistent low back pain. It is challenging to evaluate the effectiveness of this educational effort. Models have varied from brochures, booklets and simple office conversations to formal scheduled classes. Content has ranged from purely mechanical instruction to complex cognitive behavioural therapy. Essential to success is the ability to integrate the instructions into activities of daily living. The composition of those lessons remains the subject of continuing debate.
Key Words: Back School, education, body mechanics, prevention, pain management.

Back education programs do not reduce the frequency or severity of future back pain attacks.
The educational message should be consistent, frequent and stress self-management.
Group education is useful but the message must be tailored to the individual.
Information must be integrated into the patient's daily routine.
Back education should be part of rehabilitation and is probably most effective during the sub-acute phase of recovery when the pain is still present but not so distracting that it prevents learning.
Comprehensive back school includes spinal anatomy, instruction in proper body mechanics, individualized pain control techniques plus the recognition and treatment of pain disorder through cognitive behavioural therapy when required.
The back program should follow the precepts of adult education with frequent interaction, problem solving, practical applications and a focus on participation.
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: Dermatology is a visual specialty, yet palpation can also play an important diagnostic role. We present five dermatologic diagnoses that can be made at point of care by palpation or physical manoeuvres, potentially reducing unnecessary investigations, such as biopsies.
Key Words: Dermatofibromas, pilomatricomas, mastocytomas, spider angiomas, terra firma-forme dermatitis.
Dermatofibromas and pilomatricomas are benign papulonodular lesions that can be differentiated by the dimple sign, and the teeter-totter sign or tent sign, respectively.
Solitary mastocytomas can be diagnosed by Darier sign, whereby rubbing of the lesion causes a wheal and pruritus.
Spider angiomas can be diagnosed by diascopy, which involves the application of gentle downward pressure with a glass slide on the skin, resulting in blanching of the telangiectasia.
Terra firma-forme dermatitis is a benign discoloration that can be diagnosed, and treated, by gentle rubbing with isopropyl alcohol.
These dermatologic physical examination manoeuvres are quick, cost-effective, point-of-care diagnostic tools.
If in doubt, do not hesitate to biopsy lesions that appear suspicious.
