Physical Examination

Importance Shoulder pain is a common and disabling condition most often managed in primary care. This review provides an evidence-based update on the diagnosis and management of shoulder pain to support clinical decision-making and improve patient outcomes.

Observations Shoulder pain arises from benign, self-limiting soft-tissue disorders or rare but serious causes. In primary care, most cases are nontraumatic and involve periarticular soft tissues. The subacromial region is the most frequent source of pain, and the term subacromial pain is preferred over overlapping and inconsistently defined labels such as rotator cuff tendinopathy or tear, impingement syndrome, or subacromial bursitis. Less commonly, pain originates from the glenohumeral joint, as in glenohumeral osteoarthritis or adhesive capsulitis. Assessment should focus on a detailed history and physical examination to assess pain patterns and movement limitation and to exclude serious causes, such as infection, malignant neoplasm, or nonshoulder referred pain. Once these are excluded, first-line treatment is similar for most patients and aligns with recommended care for other regional musculoskeletal concerns: education about the favorable natural history, symptom relief and activity modification if needed, and watchful waiting. Early imaging is not indicated in the absence of significant trauma or suspicious features, such as fever, unexplained weight loss, or history of malignant neoplasm, as structural abnormalities often do not correlate with symptoms, rarely alter management, and may lead to overdiagnosis and overtreatment. Specialist referral should be reserved for suspected serious pathology, such as infection, malignant neoplasm, fracture, or dislocation; significant functional or neurologic deficit; features suggestive of systemic inflammatory disease; or persistent or worsening pain and debility. High-certainty evidence indicates that subacromial pain does not benefit from surgical intervention.

Conclusions and Relevance Shoulder pain is the third most common musculoskeletal presentation in primary care. Although causes vary, the initial management is largely the same once serious conditions have been excluded. Most patients with subacromial pain will fully recover with minimal intervention and can be safely treated with supportive care. Imaging and referral to surgical subspecialists should be reserved for rare and carefully selected cases to avoid unnecessary intervention.

A 43-year-old woman presented with a 1-year history of recurring symptoms of sudden onset of fatigue, palpitations, dyspnea, chest pain, lightheadedness, and nausea that were associated with standing and resolved with sitting. These symptoms began 1 month after mild COVID-19 infection. At presentation, while supine, blood pressure (BP) was 123/70 mm Hg and heart rate (HR) was 90/min; while seated, BP was 120/80 and HR was 93/min; after standing for 1 minute, BP was 124/80 and HR was 119/min. Physical examination results were normal. Oxygen saturation was 98% at rest while breathing room air. She had no oxygen desaturation during a 6-minute walk test but walked only 282 m (45% predicted). Complete blood cell count, morning cortisol, and thyrotropin blood levels were normal. Electrocardiogram (ECG), chest computed tomography, pulmonary function testing, methacholine challenge, bronchoscopy, echocardiography, and cardiac catheterization findings were normal. During tilt table testing, the patient experienced lightheadedness and nausea when moved from horizontal to the upright position. Results of the tilt table test are shown in the Table and Figure.

Objective To provide family physicians with a practical evidence-based approach to the management of patients with sialadenitis.

Sources of information MEDLINE and PubMed databases were searched for English-language research on sialadenitis and other salivary gland disorders, as well as for relevant review articles and guidelines published between 1981 and 2021.

Main message Sialadenitis refers to inflammation or infection of the salivary glands and is a condition that can be caused by a broad range of processes including infectious, obstructive, and autoimmune. History and physical examination play important roles in directing management, while imaging is often useful to establish a diagnosis. Red flags such as suspected abscess formation, signs of respiratory obstruction, facial paresis, and fixation of a mass to underlying tissue should prompt urgent referral to head and neck surgery or a visit to the emergency department.

Conclusion Family physicians can play an important role in the diagnosis and management of sialadenitis. Prompt recognition and treatment of the condition can prevent the development of complications.

Sialadenitis is inflammation or infection of the salivary glands that can present acutely or chronically. Sialadenitis can cause serious discomfort in everyday activities such as chewing food. There are numerous pathologies that can cause sialadenitis, which are reviewed below.

Abstract

Importance: Current clinical guidelines recommend selecting diagnostic tests for giant cell arteritis (GCA) based on pretest probability that the disease is present, but how pretest probability should be estimated remains unclear.

Objective: To evaluate the diagnostic accuracy of symptoms, physical signs, and laboratory tests for suspected GCA.

Data sources: PubMed, EMBASE, and the Cochrane Database of Systematic Reviews were searched from November 1940 through April 5, 2020.

Study selection: Trials and observational studies describing patients with suspected GCA, using an appropriate reference standard for GCA (temporal artery biopsy, imaging test, or clinical diagnosis), and with available data for at least 1 symptom, physical sign, or laboratory test.

Data extraction and synthesis: Screening, full text review, quality assessment, and data extraction by 2 investigators. Diagnostic test meta-analysis used a bivariate model.

Main outcome(s) and measures: Diagnostic accuracy parameters, including positive and negative likelihood ratios (LRs).

Results: In 68 unique studies (14 037 unique patients with suspected GCA; of 7798 patients with sex reported, 5193 were women [66.6%]), findings associated with a diagnosis of GCA included limb claudication (positive LR, 6.01; 95% CI, 1.38-26.16), jaw claudication (positive LR, 4.90; 95% CI, 3.74-6.41), temporal artery thickening (positive LR, 4.70; 95% CI, 2.65-8.33), temporal artery loss of pulse (positive LR, 3.25; 95% CI, 2.49-4.23), platelet count of greater than 400 × 103/μL (positive LR, 3.75; 95% CI, 2.12-6.64), temporal tenderness (positive LR, 3.14; 95% CI, 1.14-8.65), and erythrocyte sedimentation rate greater than 100 mm/h (positive LR, 3.11; 95% CI, 1.43-6.78). Findings that were associated with absence of GCA included the absence of erythrocyte sedimentation rate of greater than 40 mm/h (negative LR, 0.18; 95% CI, 0.08-0.44), absence of C-reactive protein level of 2.5 mg/dL or more (negative LR, 0.38; 95% CI, 0.25-0.59), and absence of age over 70 years (negative LR, 0.48; 95% CI, 0.27-0.86).

Conclusions and relevance: This study identifies the clinical and laboratory features that are most informative for a diagnosis of GCA, although no single feature was strong enough to confirm or refute the diagnosis if taken alone. Combinations of these symptoms might help direct further investigation, such as vascular imaging, temporal artery biopsy, or seeking evaluation for alternative diagnoses.
