Study Notes
Risk Factors for Low Back Pain
- 65% of cases are managed by General Practitioners (GPs) as sole providers.
Physical Factors
- Prolonged standing and walking can contribute to low back pain.
- Lifting heavy weights increases the risk of back injury.
Unhealthy Lifestyle Choices
- Smoking is a significant risk factor.
- Obesity contributes to low back pain incidence.
Psychological Factors
- Conditions such as depression and job dissatisfaction may exacerbate back pain symptoms.
- A history of prior episodes of low back pain can predispose individuals to future occurrences.
Etiology of Low Back Pain
- 90% of low back pain cases are classified as non-specific.
- Among primary care patients:
- Compression fractures account for 4%.
- Spinal stenosis contributes to 3%.
- Visceral diseases represent 2%.
- Tumors or metastases are found in 0.7%.
- Infections are extremely rare at 0.01%.
Differential Diagnosis of Back Pain
- Differential diagnosis includes back pain due to:
Musculoskeletal Disorders
- Most common cause of low back pain.
- Nonspecific (mechanical) back pain and specific MSK back pain related to anatomical abnormalities.
- Conditions such as lumbar radiculopathy, spinal stenosis, and cauda equina syndrome are notable red flags.
Systemic Diseases Affecting the Spine
-
Serious conditions requiring urgent treatment include:
- Neoplasia (cancer).
- Infection-related issues.
-
Non-emergent yet serious conditions include osteoporotic compression fractures and inflammatory arthritis.
Visceral Disease
- Serious illnesses involving pelvic, renal, or gastrointestinal structures must be considered.
Assessment for Back Pain
- Conduct a structured pain history to identify:
- Onset, provoking/palliating factors, quality, region/radiation, severity, and timing.
- Utilize scales such as GAD-7 and HAM-D for mood assessment.
- Early identification of red flags and yellow flags is essential.
History of Presenting Illness
- Important history components:
- Onset, location, quality, and any radiation of pain.
- History of alleviating or aggravating factors and previous treatments.
- Associated symptoms such as sensory loss, motor deficits, systemic symptoms (fever/weight loss), and bowel/bladder incontinence.
Physical Examination
-
Inspection: Examine the spine for shape abnormalities (kyphosis, scoliosis) and any asymmetry, swelling, or bruising.
-
Range of Motion/Gait: Evaluate active range of motion and gait pattern.
-
Palpation: Assess for tenderness along the spine and paraspinal muscles; perform straight leg raises for neurological deficits.
-
Neurological Exam: Test sensation and reflexes related to specific nerve roots (L4, L5, S1) and assess for saddle anesthesia.
Mechanical vs. Nonmechanical Back Pain
-
Mechanical pain indicators may include lumbar strain, degenerative diseases, herniated discs, and fractures.
-
Nonmechanical back pain requires evaluation for potential neoplasia or infection.
Red Flags for Serious Conditions
-
General red flags include significant vascular history, unexplained weight loss, night pain, and fever.
-
Specific conditions such as cauda equina syndrome warrant immediate attention, including urinary retention and significant motor deficits.
Lab Tests
-
Complete Blood Count (CBC): Measures various blood parameters; useful for detecting infections.
-
C-Reactive Protein (CRP): Acute phase protein indicative of inflammation; rises due to infections or immune-mediated diseases.
-
Erythrocyte Sedimentation Rate (ESR): Non-specific test for inflammation; elevated during inflammatory, neoplastic, and infectious diseases.
Imaging in Back Pain Management
- Consider MRI for neurological deficits or red flag symptoms.
- Utilize plain radiography for initial assessments but follow up with advanced imaging based on clinical suspicion.### MRI and Vertebral Compression Fractures
- MRI is contraindicated in patients with high risk for vertebral compression fractures due to advanced age, prolonged systemic steroid use, significant trauma, or mild trauma when osteoporosis risk factors are present.
- Plain radiography is utilized to assess fractures, indicating whether further imaging is necessary.
Management of Low Back Pain
- For low back pain without serious features and low cancer or infection risk, conservative therapy is recommended for 4-6 weeks.
- If symptoms remain unchanged after 4-6 weeks, further evaluation for subacute low back pain is necessary.
Indicators of Spinal Infection
- Important signs of spinal infection include:
- Objective fever
- Immunosuppression, such as from current therapies or hemodialysis
- Current or recent bacteremia, injection drug use, endocarditis, or history of invasive epidural/spinal procedures.
Evaluation of Spinal Infection Risk
- A high level of suspicion for spinal infection warrants an MRI.
- If the suspicion is low, ESR (Erythrocyte Sedimentation Rate) and/or CRP (C-Reactive Protein) tests are recommended as preliminary assessments.
Non-Specific Low Back Pain
- Non-specific low back pain (NSLBP) without an identifiable cause should be carefully monitored to determine management and potential need for further imaging or interventions.
Learning Objectives
- Compare medical tests for abdominal pain evaluation based on accuracy.
- Apply diagnostic evidence to clinical reasoning for abdominal pain cases.
- Prioritize issues in encounters involving abdominal pain.
- Refine differential diagnoses based on new patient information.
- Perform examinations and procedures safely in abdominal pain scenarios.
- Utilize strategic patient-centered interviewing to build rapport.
Abdominal Pain: Locations and Differential Diagnoses
- Epigastric pain may indicate cholecystitis, myocardial infarction, gastric issues, or pancreatitis.
- Right upper quadrant pain can suggest biliary problems, hepatic conditions, renal issues, or pulmonary concerns.
- Left upper quadrant pain may signal gastric, vascular, renal, or colonic issues.
- Periumbilical pain is associated with vascular conditions or colonic issues like appendicitis and IBD.
- Right lower quadrant pain can indicate gynecological issues, renal stones, or colonic conditions, notably appendicitis.
- Suprapubic pain points to gynecological, renal, and colonic issues.
- Any abdominal location can relate to bowel obstruction, peritonitis, IBD, and narcotic withdrawal.
Must Not Miss Conditions with Abdominal Pain
- Appendicitis
- Bowel obstruction
- Abdominal malignancy
- Cardiovascular causes, including AAA and mesenteric ischemia
- Gynecological emergencies like PID and ectopic pregnancy
Appendicitis
- Epidemiology: 1.1% of adults and 10-25% of children with abdominal pain have appendicitis.
- Symptoms include right lower quadrant pain, migrating pain from the periumbilical area, and abdominal rigidity.
- Key signs: Positive psoas sign and pain at McBurney’s point on palpation.
- Investigations: Abdominal CT scan is highly effective for diagnosis; ultrasound is preferred in pregnancy.
- Prognosis: Immediate treatment is essential to prevent ischemia, necrosis, and potential mortality in untreated cases.
Bowel Obstruction
- Accounts for 4% of abdominal pain cases, with the majority involving small bowel obstructions.
- Etiology: In large bowel obstructions, cancer is the most common cause; in small bowel obstructions, postsurgical adhesions are predominant.
- Symptoms often start as intermittent pain, later becoming constant with diminished bowel sounds.
- Investigations include CT scans and X-rays, with high specificity and sensitivity.
- Prognosis varies: Complete SBO has a risk of strangulation; most LBO cases resolve with treatment.
Abdominal Malignancy
- Include types such as colorectal, gynecological, pancreatic, and gastric cancers.
- Important risk factors: Family history, lifestyle, age, and the need for proper cancer screening.
- Symptoms like unintended weight loss and loss of appetite warrant further investigation.
Cardiovascular Origins of Abdominal Pain
- Conditions include AAA, myocardial infarction, pericarditis, and mesenteric ischemia.
- Recognition of these risks is critical due to possible life-threatening outcomes.
Gastrointestinal Issues Overview
- Dyspepsia: Can be associated with H. pylori, NSAID use, alcohol consumption, and stress. Symptoms include epigastric pain, nausea/vomiting, loss of appetite, and melena. Diagnosis typically through upper endoscopy. Most cases resolve, but there is a risk of ulceration or cancer.
- Peptic Ulcer Disease (PUD): Localized erosion of the stomach or small intestine mucosa. Risk factors include H. pylori and NSAID use. 15-25% of dyspepsia patients may present with PUD. Management may require antibiotics.
- Carbohydrate Malabsorption: Inability to digest certain carbohydrates leads to symptoms like abdominal pain, bloating, and diarrhea. Diagnosis involves hydrogen breath testing, confirming malabsorption with a rise in hydrogen concentration after ingesting carbohydrates.
- Small Intestine Bacterial Overgrowth (SIBO): Excessive bacteria in the small intestine, prevalent in 15% of the general population and 40% in IBS patients. Associated with abdominal pain, bloating, and either diarrhea or constipation. Breath tests are used for diagnosis. Untreated SIBO can lead to serious complications.
Celiac Disease and Non-Celiac Gluten Sensitivity
- Celiac Disease: An autoimmune disorder triggered by gluten in genetically susceptible individuals. Symptoms may include diarrhea, weight loss, fatigue, and nutritional deficiencies. Diagnosis via serologic testing and small bowel biopsy; management involves strict gluten avoidance.
- Non-Celiac Gluten Sensitivity: Characterized by digestive and extra-intestinal symptoms in the absence of celiac disease. Approximately 0.5-13% of the population may be affected. Management focuses on gluten restriction.
Disordered Eating
-
Types of Eating Disorders:
- Anorexia Nervosa: Characterized by restricted energy intake, intense fear of weight gain, and distorted body image, primarily in adolescent females. Associated health risks include arrhythmia, osteoporosis, and increased mortality risk. Diagnosis is based on DSM-5 criteria, BMI, and various laboratory tests.
- Bulimia Nervosa: Involves recurrent binge eating followed by compensatory behaviors to prevent weight gain. Diagnosis follows DSM-5 criteria.
- Binge-Eating Disorder: Defined by recurrent episodes of eating large quantities of food with a sense of lack of control. Common in females and adolescents, with high rates of obesity.
- Avoidant/Restrictive Food Intake Disorder: Characterized by avoidance of food intake leading to significant weight loss and nutritional deficiency.
- Orthorexia Nervosa: Obsessive focus on eating only healthy foods, leading to restrictive eating patterns.
Diagnostic Testing and Prognosis
- Upper Endoscopy: Standard method for diagnosing dyspepsia and related conditions.
- Hydrogen Breath Tests: Useful for diagnosing lactose intolerance and SIBO, based on breath hydrogen concentration changes after carbohydrate ingestion. High sensitivity for lactose (up to 95%) and fructose (up to 98%).
- Prognosis for Eating Disorders: Varies significantly; up to 90% may resolve binge-eating disorder with collaborative management, while anorexia nervosa has a 5.9X increased risk of mortality.
Clinical Considerations
- Differential Diagnosis: Essential for conditions presenting with dyspepsia, loose stools, or disordered eating. Continuous updating of knowledge based on new information is critical.
- Referral Criteria: A clear understanding of when to refer patients for higher-level care is essential in managing gastrointestinal symptoms and eating disorders effectively.
Learning Outcomes
- Recognize various conditions classified as cardiovascular disease, emphasizing critical conditions that must not be missed.
- Integrate diagnostic evidence into clinical reasoning for assessing cardiovascular diseases.
- Identify medical tests used for evaluating patients suspected of having cardiovascular disease, focusing on accuracy.
- Utilize cardiovascular risk assessment tools to determine individual patient risk.

- Signs and symptoms aiding diagnosis include:
- Radiation of pain to both arms (LR + 9.7), right arm (LR + 7.3), left arm (LR + 2.2), and right shoulder (LR + 2.2).
- Third heart sound (LR + 3.2) and hypotension (LR + 3.1).
- Diaphoresis, crackles on auscultation, and gastrointestinal symptoms (nausea, vomiting).
- Specific symptoms with low likelihood ratios for ruling out acute coronary syndrome include:
- Stabbing, pleuritic pain; positional or reproducible pain (LR - 0.2-0.3).
Erectile Dysfunction and Cardiovascular Disease
- Strong correlation exists between erectile dysfunction (ED) and cardiovascular disease (CVD).
- ED may indicate undiagnosed CVD; patients presenting with ED should undergo cardiovascular assessment.
- Hispanic and African American men report ED more frequently than Caucasian men, particularly under 50.
Risk Factors for Erectile Dysfunction
- Cardiovascular and non-cardiovascular risk factors for ED are significant.
- Common risk factors include diabetes, hypertension, elevated cholesterol, smoking, and obesity.
- Causes of ED are divided into psychogenic (20%), vascular (32%), and others including drug-induced (12-25%), hormonal (3-19%), and neurogenic (4%).
Causes of Erectile Dysfunction
- Vasculogenic issues related to chronic renal failure and cardiovascular conditions are common.
- Hormonal imbalances (hypogonadism, thyroid disorders) and metabolic syndrome can cause ED.
- Psychogenic causes include anxiety, depression, and relationship stressors.
Medical Diagnosis and Evaluation
- Comprehensive medical history and physical examination are crucial for diagnosing ED.
- Assess psychosocial factors impacting sexual performance.
- Utilize validated questionnaires, such as the International Index of Erectile Function (IIEF), for an accurate diagnosis of ED severity.
IIEF Testing
- The IIEF includes 15 items assessing erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction.
- Scores range from normal erectile function (26-30) to severe ED (6-10).
- SHIM (Sexual Health Inventory for Men) is a shortened version used as a screening tool.
Approach to Patient Care
- Prioritize addressing psychological factors and assessing current medications affecting sexual health.
- Consider other sexual dysfunctions such as premature ejaculation and loss of libido.
- Use strategic, patient-centered interviewing skills to build rapport and promote open communication.
Differential Diagnosis
- Differentiate ED from other causes based on presenting symptoms like known psychological stressors or recent drug use.
- Evaluate for conditions associated with pelvic trauma, thyroid disease, or neurological issues in patients with concerning symptoms.
Physical Examination Considerations
- Inspect for penile deformities and signs of cardiovascular disease or hypogonadism.
- Review dietary patterns and lifestyle habits, including tobacco use and physical activity levels.
- Screen for depression, which can be a significant contributing factor to ED.
Common Diagnostic Tools
- Framingham Risk Score helps estimate a patient's 10-year risk of CVD using factors such as age, HDL levels, and blood pressure.
- The STOP-Bang questionnaire may assess sleep apnea risk if indicated.
Key Notes on Management
- Treatment options for ED related to drugs, psychogenic factors, or hormonal imbalances are typically effective.
- Identify and address reversible factors contributing to ED for optimal outcomes.
- Early recognition and management of potential underlying cardiovascular issues are critical in male patients with ED.
Gastrointestinal Bleeding Overview
- Gastrointestinal (GI) bleeding can be categorized as overt or occult.
- Overt GI bleed presents with visible blood, including hematemesis, melena, or hematochezia.
- Occult GI bleed refers to microscopic blood loss that is not visible to the naked eye.
- Obscure GI bleed occurs when the source remains unidentified despite investigation.
Alarm Symptoms for GI Bleeding
- Symptoms indicating need for urgent assessment:
- Blood in stools or vomit
- Unintentional weight loss exceeding 10%
- Awakening from sleep due to symptoms
- Fever above 38.0°C (100.4°F)
- New signs or symptoms in individuals over 50 years of age
- Family history of colorectal cancer, inflammatory bowel disease (IBD), or celiac disease
- Unexplained anemia or elevated white blood cell count
- Presence of abdominal mass
Diarrhea Classification
- Loose, watery stools occurring three or more times daily.
- Acute diarrhea lasts 1-2 days, often self-resolving.
- Persistent diarrhea occurs between 2-4 weeks.
- Chronic diarrhea persists for 4 weeks or longer, either continuously or intermittently.
Prevalence of GI Bleeding Causes
-
Upper GI tract:
- Peptic ulcer disease: 40-79%
- Gastritis/duodenitis: 5-30%
- Esophageal varices: 6-21%
- Mallory-Weiss tear: 3-15%
- Esophagitis: 2-8%
- Gastric cancer: 2-3%
-
Lower GI tract:
- Small intestine angiodysplasia: 70-80%
- Diverticular disease: 17-40%
- Arteriovenous malformations: 2-30%
- Colitis: 9-21%
- Colonic neoplasms: 11-14%
- Anorectal causes: 4-10%
Diagnosis and Management
- Utilize the Glasgow-Blatchford Bleeding Score (GBS) for pre-endoscopic risk assessment of upper GI bleeding.
- A GBS score of ≤1 suggests high likelihood of survival without intervention.
- Initial evaluation may involve upper endoscopy or colonoscopy based on clinical presentation.
- Referral decisions may depend on GBS score and patient stability, distinguishing between massive bleeding and low-volume situations.
Colorectal Cancer Screening
- Understand and adhere to established colorectal cancer screening guidelines to detect abnormalities early.
