Neurological and Developmental Milestones

Upper and Lower Motor Neuron Lesions

  • Upper Motor Neuron Lesion

    • Symptoms: hyperreflexia, increased muscle tone, positive Babinski sign.
    • Indication: Damage above anterior horn cells in the spinal cord or brain.

  • Lower Motor Neuron Lesion

    • Symptoms: hyporeflexia, decreased muscle tone, muscle atrophy.
    • Note: Lesion affects the ipsilateral side of the body when spinal cord-related.

Diabetic Neuropathy

  • Affected Sensation: Vibration sense, especially in feet and legs.
  • Cause: Damage to larger myelinated fibers that conduct proprioception and vibration.

Corneal Reflex

  • Functionality: Tests cranial nerves V (trigeminal) for sensory and VII (facial) for motor.
  • Mechanism: Trigeminal senses touch on the cornea, facial nerve causes blink response.

Tremors and Neurological Symptoms

  • Resting "Pill-Rolling" Tremor
    • Significance: Indicative of Parkinson's disease.

Hemorrhagic Stroke Risks

  • Common Risk Factors:
    • Hypertension
    • Anticoagulant therapy
    • Aneurysms
    • Arteriovenous malformations (AVMs)
  • Prevention: Patients should control blood pressure and remain cautious with bleeding-increasing medications.

Patella Reflex

  • Spinal Nerves Tested: L3 and L4.
  • Usage: Common neurological exam test for femoral nerve integrity.

Proprioception Testing

  • Toe Up/Down with Eyes Closed:
    • Functionality: Tests proprioception, the sense of body position, particularly of toes; involves sensory pathways.

Dysdiadochokinesia

  • Definition: Inability to rapidly alternate movements; associated with cerebellar dysfunction.

Asterixis

  • Characteristic: Non-rhythmic flapping hand movements when arms held up; suggests hepatic encephalopathy or other metabolic disorders.

Mental Health Screening

  • PHQ-2 Tool: Quick initial depression screening focusing on two questions.
  • Follow-Up: Positive PHQ-2 leads to PHQ-9 for a comprehensive evaluation.

Mini Mental Status Exam (MMSE)

  • Indication: Used suspected cognitive impairment or dementia; assesses memory, attention, language, and orientation.

Cognitive Function Tests

  • World Spelling Backwards:
    • Tests: Attention, working memory, cognitive flexibility.
  • Abstract Thinking:
    • Assessment: Explain a phrase like "rolling stone"; higher-level cognitive function test.
  • Flat Affect: Lack of emotional expression, seen in depression, schizophrenia, neurological disorders.
  • Blunted Affect: Minimal emotional response, often associated with schizophrenia.

Levels of Consciousness

  • Terms:
    • Lethargic: Drowsy, responds to voice but falls asleep.
    • Stuporous: Requires vigorous stimuli to arouse; limited response.
    • Obtunded: Responds to gentle shaking or loud voice; slow.
    • Comatose: No response to stimuli.

Developmental Milestones

  • Moro Reflex: Disappears by 4 months.
  • Urinary Continence: Expected by age 4.
  • Sitting with Minimal Support: Achieved around 6 months.
  • Low-Fat Diet: Not before 2 years due to brain development needs.

Neonatal Fever Management

  • Emergency: Temp ≥ 100.4°F (38°C) requires full sepsis workup.
  • Next Steps: CBC, blood cultures, UA, urine cultures, LP, IV antibiotics.
  • Height/Weight: Important for dosing; focus on fever workup first.

Premature Infants

  • Risks: Increased risk for developmental delays (e.g., lack of sitting at 6 months can be appropriate for preterm infants).

Car Seat Guidelines

  • Infants & Toddlers: Rear-facing until age 2 or exceeding manufacturer limits.
  • Toddlers & Preschoolers: Forward-facing with harness until about 4-7 years old.
  • School-aged: Booster seat until seat belt fits properly (around 4'9" and ages 8–12).
  • Older Children: Seat belt in back seat until at least 13.

Adolescent Health

  • Leading cause of death in ages 15-24: Unintentional injuries.
  • Suicide: Significant but not the leading cause.
  • Consent for Reproductive Health:
    • YES: 13-year-old can consent for birth control.
    • NO: Cannot consent to sterilization procedures.

Tanner Stages

  • Stage 1: Prepubertal.
  • Stage 2: Breast buds in girls, testicular enlargement in boys.
  • Stage 3: Sparse pubic hair, further changes in breast and penile development.
  • Stage 4: Secondary mound formation in females, scrotal darkening in males.
  • Stage 5: Adult genitalia/pubic hair.

Neonatal Ear Anomalies

  • Indicators: Low-set or malformed ears may suggest genetic syndromes; evaluate for kidney anomalies due to concurrent embryological development.

Hyperthyroidism

  • Risks: Increases osteoporosis risk; may require DEXA screening in long-term cases.
  • Management: Calcium + vitamin D supplementation, potential bisphosphonates.

Blood Pressure and Associations

  • Normal reading: Systolic 120/58 mmHg; pulse pressure 62 mmHg (widely considered widened).
  • Associations with Wide Pulse Pressure:
    • Hyperthyroidism
    • Aortic regurgitation
    • Anemia
    • Aging (arterial stiffness)
    • AV fistulas.

Frailty Criteria in Older Adults

  • Diagnosis: Presence of 3 or more of the following:
    • Weakness (decreased grip strength)
    • Slow walking speed
    • Exhaustion
    • Low physical activity
    • Unintentional weight loss.

Pressure Ulcers

  • Common Site: Sacrum, due to prolonged pressure in bedridden patients.
  • Prevention: Repositioning every 2 hours, pressure-relieving mattresses, good skin care, and nutrition.

Activities of Daily Living (ADLs) & IADLs

  • ADLs: Bathing, dressing, toileting, feeding, grooming, mobility.
  • IADLs: Managing finances, transportation, housekeeping, medication management, shopping, meal preparation.

Pap Smear Screening

  • Guidelines: Stop > age 65 if prior adequate screenings and no high-risk factors.

Normal Skin and Hair Changes with Aging

  • Skin: ↓ collagen, ↓ elastin, ↑ transparency.
  • Hair: ↓ pigmentation, ↓ shaft diameter.

    1. Chief Complaint
    2. History of Present Illness (HPI)
    3. Past Medical History (PMHx)
    4. Medications
    5. Allergies (including reactions!)

    3. Skin, Hair, Nails
    4. HEENT (Head, Eyes, Ears, Nose, Throat)
    5. Neck

    9. Abdomen
  1. Breast
  2. Genitourinary/Rectal

Review of Systems (ROS) Importance

  • Benefits: Determines localization vs systemic issues, narrows differential diagnosis, identifies unreported symptoms, provides a comprehensive clinical picture.

Clinical Documentation Tips

  • Allergies: Be specific (details about medication reactions, environmental triggers, etc.).
  • Importance: Enhances clarity in emergencies, informs treatment, essential for documentation & billing accuracy.

Standard Database for EMR

  • Inclusions: Medications, detailed allergies, past medical history, surgical history, family history, and social history.

Complete Physical Exams

  • Routine Scenarios: First-time visits, school/employment physicals.
  • Not Routine: Emergency settings focusing on stabilization rather than complete exams.

Breast Lymphatic Drainage & Support

  • Primary drainage site: Axillary lymph nodes, particularly the anterior/pectoral group.
  • Structural Support: Suspensory ligaments of Cooper maintain breast shape.
