Study Notes
Normal Anatomy
- The chest wall is made up of skin, subcutaneous tissue, ribs, intercostal muscles, and the pleura.
- The lungs are located in the thorax, which is the space between the neck and the abdomen.
- The lungs are divided into lobes, with the right lung having three lobes and the left lung having two.
- The trachea branches into the right and left main bronchi, which further branch into bronchioles and alveoli.
- The alveoli are responsible for gas exchange between the lungs and the blood.
HPI: Cough
- Cough can be a symptom of various conditions, including respiratory infections, asthma, allergies, and heart failure.
- Characteristics of cough to consider in patient history:
- Onset: When did the cough start?
- Duration: How long has the cough lasted?
- Frequency: How often does the cough occur?
- Severity: How bad is the cough?
- Productive: Does the cough produce phlegm/sputum? If so, what color is the sputum?
HPI: Shortness of Breath (SOB)
- SOB can be a symptom of various conditions, including lung conditions, heart conditions, and anxiety.
- Important information to collect from the patient includes:
- Onset: When did the SOB start?
- Duration: How long does the SOB last?
- Triggering factors: What makes the SOB worse?
- Severity: How bad is the SOB?
- Positional dependence: Does the SOB change based on position?
HPI: Wheezing
- Wheezing is a high-pitched whistling sound that occurs during breathing.
- Wheezing is commonly associated with asthma and other obstructive airway diseases.
- Questions to ask the patient:
- When does wheezing occur?
- What are the characteristics of the wheezing? (e.g., loudness, pitch)
Review of Systems (ROS)
- It's critical to inquire about respiratory and environmental exposure history.
- Questions to ask include:
- History of smoking or exposure to smoke.
- Recent travel to areas with potential respiratory hazards (e.g., polluted cities, areas with endemic diseases).
- History of allergies (e.g., pollen, dust mites, mold).
- History of occupational exposure hazards (e.g., dust, fumes, chemicals).
Physical Exam for Respiratory Concern
- The physical exam is an essential part of assessing a patient's respiratory status.
- The goal is to detect abnormalities such as fluid, air, consolidation, or masses.
- Key steps of physical exam include:
- Inspection: Observing the patient's breathing pattern, chest wall movement, skin color, use of accessory muscles.
- Palpation: Feeling the chest wall for tenderness, masses, or changes in vibrations (vocal fremitus).
- Percussion: Tapping on the chest wall to assess the sound produced (dullness, resonance, tympany).
- Auscultation: Listening to the chest with a stethoscope to assess lung sounds, heart sounds, and vocal resonance.
Abnormal Chest Findings
- AP diameter: Normally, the anterior-posterior diameter of the chest is about half the lateral diameter. (2:1 ratio)
- Barrel chest: Seen in COPD and other lung diseases, where there is a 1:1 ratio in the AP diameter.
- Pectus excavatum: "Funnel chest" where there is a hollowness or indentation in the chest wall.
- Pectus carinatum: "Pigeon chest" where there is a protrusion or hump in the chest wall.
- Respiratory distress: Observe for signs of distress, such as increased respiratory rate, use of accessory muscles, and cyanosis.
- Hyperpnea: Deeper than normal breaths that can occur with or without increased respiratory rate.
- Cheyne-Stokes respiration: A cyclical pattern of increasing and decreasing breathing that culminates in a temporary pause (apnea).
- Paradoxical breathing: Chest wall moves inward during inhalation and outward during exhalation (opposite of normal breathing).
Diaphragmatic Excursion
- This is the movement of the diaphragm during breathing.
- It is assessed by having the patient take a deep breath and listen for the change in percussion sounds as you percuss the lung fields.
Vocal Fremitus
- Tactile fremitus assesses the intensity of vibrations transmitted through the lungs by spoken words.
- Increased vocal fremitus can be caused by consolidation, i.e., pneumonia, lung abscess, inflammation, and consolidation.
- Decreased vocal fremitus can be caused by pleural effusion, pneumothorax, emphysema/COPD, bronchial obstruction, and bronchial asthma.
Auscultation: Changes in Breath Sounds and Vocal Resonance
- Diminished breath sounds: Can indicate a problem with the transmission of sound from the lungs to the stethoscope.
- Bronchophony: Louder sound over an area of consolidation.
- Whispering pectoriloquy: Whispered words are heard clearly in the presence of consolidation.
- Egophony: A qualitative change in voice, where the "E" sound is perceived as "A" or "AAAH."
Case Study: Patient With Shortness of Breath
- Scenario: 65-year-old Caucasian male with progressive shortness of breath when walking.
- Pertinent Positives: Breathlessness at night, dry cough, dyspnea on exertion, peripheral edema.
- Potential Diagnosis: Heart failure (HF)
Heart Failure (HF) Symptoms
- S3 gallop
- JVD (Jugular venous distention)
- Hepatomegaly (enlarged liver)
- Splenomegaly (enlarged spleen)
- Crackles (rales)
- Wheezing
- Peripheral edema
- Positive hepatojugular reflex
Lab Articles: Cardiovascular Disease and Risk Management
-
Recommendations for Screening and Prevention of Cardiovascular Disease:
- Screen for risk factors like hypertension, high cholesterol, diabetes, and smoking.
- Implement lifestyle modifications and medication therapy for risk factors.
- Advocate for regular exercise and healthy diet.
Assessing and Managing Metabolic Syndrome
- Metabolic syndrome is a cluster of conditions that increase a person’s risk for heart disease, stroke, and type 2 diabetes.
- Criteria: Includes abdominal obesity, high blood pressure, high blood sugar, high triglycerides, and low HDL cholesterol.
- Management: Includes lifestyle modifications, medication therapy, and regular monitoring.
The 5 A’s For Obesity Management
- The "5 A's" framework for obesity management is a tool to guide healthcare providers through the process of counseling and managing patients with obesity:
- Ask: About the patient's weight and weight history.
- Assess: For potential risk factors contributing to obesity and related health conditions.
- Advise: On the benefits of losing weight and making lifestyle changes.
- Agree: On achievable weight loss goals and a plan for achieving them.
- Assist: By providing resources, support, and ongoing guidance.
Clubfoot
- Complex foot deformity with four key characteristics: cavus, adduction of forefoot, varus of hindfoot, and equinus
- Affects around 1-2 out of every 1000 babies
- Can occur without a known cause (idiopathic) or be linked to neuromuscular conditions
- Usually diagnosed based on physical examination, X-rays are rarely needed
- Treatment involves the Ponseti method using serial casting and potentially Achilles tenotomy
- After casting, children wear specialized shoes to keep their feet in the correct position for at least three months
- Recurrence is common (25-67%) and may require further casting or surgical intervention
- It's recommended to consult an orthopedic specialist familiar with the Ponseti method
- Chronic pain is a frequent complication
Calcaneovalgus Foot
- Characterized by a foot that points upward and outward
- Usually occurs when the foot is bent in an unusual position for a long time (e.g., during pregnancy)
Vertical Talus
- Rare condition that causes the talus bone in the foot to be positioned vertically
- Often diagnosed at birth or shortly after
- Associated with other skeletal abnormalities
- Requires surgery as early intervention is critical
Cavus Foot Anomaly (High-Arched Foot)
- Characterized by an unusually high arch in the foot
- Can be caused by various factors, including neuromuscular disorders and genetic conditions
