Study Notes

Eating Disorders

Anorexia nervosa has a higher female to male ratio, estimated at 5-10:1.
Bulimia can occur in individuals with a normal or high BMI, with behaviors involving caloric intake followed by purging.
Concealment of underweight appearance is common, complicating recognition in everyday attire.

Blood Pressure Measurement

Using a cuff that is too small can result in inaccurately high blood pressure readings.
A large cuff on a small arm can show falsely low BP, while vice versa can yield high readings.
White coat syndrome often leads to elevated BP readings in medical settings.
Masked hypertension refers to consistent high BP outside of the clinic that goes unrecognized.
Possible causes of blood pressure variation include medications, blood loss, extended bed rest, or autonomic nervous system diseases.

Respiratory Rates

Tachypnea is defined as a respiratory rate exceeding 25 breaths per minute.
COPDs often present prolonged expiration patterns.

Neurotransmitters and Mental Disorders

Key neurotransmitters include:
- Serotonin: synthesized in the brainstem, regulates mood and cognition.
- Norepinephrine: from the locus coeruleus, involved in mood and attention.
- Dopamine: from the substantia nigra, linked to mood, cognition, and motor control.
- Acetylcholine: synthesized in the basal forebrain, essential for sleep and attention.
Low serotonin, norepinephrine, and dopamine levels correlate with depressive symptoms; elevated dopamine with low serotonin can trigger psychosis or mania.

Common Symptoms and Examination Techniques

Symptoms of concern include anxiety, excessive worry, depressed mood, and medically unexplained issues.
Speech assessment involves evaluating rate, rhythm, volume, and patterns which can indicate mental health conditions.
Techniques to assess abstract thinking include interpreting proverbs or identifying similarities between objects.

Mental Status Examination

Assessments encompass appearance, behavior, speech, mood, thoughts, and cognition.
Identify the patient's level of consciousness, posture, grooming, and emotional affect.
Speech characteristics examine fluency and volume, potentially indicating disorders such as mania or schizophrenia.
Higher cognitive function evaluations assess orientation, memory, and abstract reasoning.

Screening for Depression

Use a questionnaire format where respondents answer YES or NO to statements about feelings in the past week.
Scores categorize depression severity: 0-4 normal, 5-8 mild, 9-11 moderate, 12-15 severe.
Various standardized screening tools include PHQ, Beck Depression Scale, and Geriatric Depression Scale.

Screening Recommendations

Professional organizations recommend screening for depression in adults, pregnant women, and adolescents aged 12-18.
Routine screenings are advised for emotional and behavioral health in adolescents.

Substance Abuse Screening

All patients should be questioned about alcohol use and substance abuse.
The USPSTF advocates for screening adults for alcohol misuse and brief intervention.

Understanding Hallucinations and Illusions

Hallucinations involve perceiving sensations without external stimuli, while illusions are misinterpretations of real stimuli.
Thought processes can be impaired in conditions like schizophrenia, leading to incoherence or circumstantiality.

Risk factors include family history, personal history of anxiety/mood disorders, and past trauma.
Characteristic disorders include OCD, generalized anxiety disorder, panic disorder, PTSD, and social anxiety.

Depressive Disorders

Differentiated by symptom duration and severity, major depressive disorder (MDD) includes at least two weeks of symptoms.
Persistent depressive disorder (PDD) lasts for a minimum of two years.
Bipolar disorder includes episodes of mania/hypomania alongside depressive phases.

Dementia and Cognitive Decline

Diagnosing dementia involves recognizing a decline in cognitive function affecting daily life.
Memory issues can signal major neurocognitive disorders, particularly after vascular occlusion or in TBI cases.
Behavior changes in patients may indicate frontotemporal dementia or Parkinson's.

Aphasia Types

Broca's aphasia demonstrates preserved comprehension with slow, non-fluent speech.
Wernicke's aphasia presents fluent speech but impaired comprehension.

Techniques for Assessing Mental Status

The Confusion Assessment Method (CAM) focuses on acute changes in cognition and attention to diagnose delirium.### Myxedema and Hypothyroidism
Myxedema is characterized by swelling and thickening of skin tissue due to mucopolysaccharide deposition.
It represents a severe manifestation of hypothyroidism.

Skin Lesion Morphology

Papule: Small solid elevation of the skin, ≤1 cm in diameter, extending into deeper layers.
Pustule: Small circumscribed elevation filled with purulent fluid.
Vesicle: Small circumscribed elevation containing clear fluid, ≤1 cm in diameter.
Wheal: Circumscribed, raised lesion due to dermal edema; also known as hives or urticaria.
- Characteristics: lasts ~6 mm, elevated, firm to palpation, may grow over weeks.

Melanoma and Skin Cancer Screening

Insufficient evidence exists for the benefits of clinician-performed visual skin examinations by the USPSTF.
Clinical skin examinations within 3 years of melanoma diagnosis lead to thinner melanomas.
At least 50% of melanomas arise from isolated melanocytes, not previous nevi.
Blue or black color in larger lesions raises melanoma concern, except in homogenous blue nevi.
Evolving lesions are the most sensitive criterion for identifying melanoma; history of change may necessitate biopsy.

Patient Screening Recommendations

The American Academy of Dermatology (AAD) and American Cancer Society (ACS) advocate regular skin self-examinations.
High-risk individuals should regularly self-examine, particularly those with:
- History of high sun exposure
- Prior or family history of melanoma
- 50+ moles or >5-10 atypical moles

Skin Conditions and Lesions

Herpes Zoster: Characterized by unilateral dermatomal vesicles.
Herpes Simplex: Presents with grouped vesicles or pustules on an erythematous base.

Blanchable Lesions: Erythematous, indicating inflammation.
Nonblanching Lesions: Include petechiae, purpura, cherry angiomas; appear bright red or violaceous due to blood extravasation.

Specific Skin Conditions

Psoriasis: Commonly affects scalp, elbows, knees, umbilicus, gluteal cleft.
Lichen Planus: Often arises on wrists, forearms, genitals, lower legs.
Vitiligo: Can be patchy or located around distal extremities, face, particularly near eyes and mouth.
Discoid Lupus Erythematosus: Presents with lesions on sun-exposed areas, especially the face.
Hidradenitis Suppurativa: Involves areas with high apocrine gland density, such as axillae, groin, under breasts.

Eating Disorders

Anorexia nervosa has a higher female to male ratio, estimated at 5-10:1.
Bulimia can occur in individuals with a normal or high BMI, with behaviors involving caloric intake followed by purging.
Concealment of underweight appearance is common, complicating recognition in everyday attire.

Lichen Planus: Often arises on wrists, forearms, genitals, lower legs.
Vitiligo: Can be patchy or located around distal extremities, face, particularly near eyes and mouth.
Discoid Lupus Erythematosus: Presents with lesions on sun-exposed areas, especially the face.
Hidradenitis Suppurativa: Involves areas with high apocrine gland density, such as axillae, groin, under breasts.

Eating Disorders

Anorexia nervosa has a higher female to male ratio, estimated at 5-10:1.
Bulimia can occur in individuals with a normal or high BMI, with behaviors involving caloric intake followed by purging.
Concealment of underweight appearance is common, complicating recognition in everyday attire.

Blood Pressure Measurement

Using a cuff that is too small can result in inaccurately high blood pressure readings.
A large cuff on a small arm can show falsely low BP, while vice versa can yield high readings.
White coat syndrome often leads to elevated BP readings in medical settings.
Masked hypertension refers to consistent high BP outside of the clinic that goes unrecognized.
Possible causes of blood pressure variation include medications, blood loss, extended bed rest, or autonomic nervous system diseases.

Respiratory Rates

Tachypnea is defined as a respiratory rate exceeding 25 breaths per minute.
COPDs often present prolonged expiration patterns.

Neurotransmitters and Mental Disorders

Key neurotransmitters include:
- Serotonin: synthesized in the brainstem, regulates mood and cognition.
- Norepinephrine: from the locus coeruleus, involved in mood and attention.
- Dopamine: from the substantia nigra, linked to mood, cognition, and motor control.
- Acetylcholine: synthesized in the basal forebrain, essential for sleep and attention.
Low serotonin, norepinephrine, and dopamine levels correlate with depressive symptoms; elevated dopamine with low serotonin can trigger psychosis or mania.

Common Symptoms and Examination Techniques

Symptoms of concern include anxiety, excessive worry, depressed mood, and medically unexplained issues.
Speech assessment involves evaluating rate, rhythm, volume, and patterns which can indicate mental health conditions.
Techniques to assess abstract thinking include interpreting proverbs or identifying similarities between objects.

Mental Status Examination

Assessments encompass appearance, behavior, speech, mood, thoughts, and cognition.
Identify the patient's level of consciousness, posture, grooming, and emotional affect.
Speech characteristics examine fluency and volume, potentially indicating disorders such as mania or schizophrenia.
Higher cognitive function evaluations assess orientation, memory, and abstract reasoning.

Screening for Depression

Use a questionnaire format where respondents answer YES or NO to statements about feelings in the past week.
Scores categorize depression severity: 0-4 normal, 5-8 mild, 9-11 moderate, 12-15 severe.
Various standardized screening tools include PHQ, Beck Depression Scale, and Geriatric Depression Scale.

Screening Recommendations

Professional organizations recommend screening for depression in adults, pregnant women, and adolescents aged 12-18.
Routine screenings are advised for emotional and behavioral health in adolescents.

Substance Abuse Screening

All patients should be questioned about alcohol use and substance abuse.
The USPSTF advocates for screening adults for alcohol misuse and brief intervention.

Understanding Hallucinations and Illusions

Hallucinations involve perceiving sensations without external stimuli, while illusions are misinterpretations of real stimuli.
Thought processes can be impaired in conditions like schizophrenia, leading to incoherence or circumstantiality.

Risk factors include family history, personal history of anxiety/mood disorders, and past trauma.
Characteristic disorders include OCD, generalized anxiety disorder, panic disorder, PTSD, and social anxiety.

Depressive Disorders

Differentiated by symptom duration and severity, major depressive disorder (MDD) includes at least two weeks of symptoms.
Persistent depressive disorder (PDD) lasts for a minimum of two years.
Bipolar disorder includes episodes of mania/hypomania alongside depressive phases.

Dementia and Cognitive Decline

Diagnosing dementia involves recognizing a decline in cognitive function affecting daily life.
Memory issues can signal major neurocognitive disorders, particularly after vascular occlusion or in TBI cases.
Behavior changes in patients may indicate frontotemporal dementia or Parkinson's.

Aphasia Types

Broca's aphasia demonstrates preserved comprehension with slow, non-fluent speech.
Wernicke's aphasia presents fluent speech but impaired comprehension.

Techniques for Assessing Mental Status

The Confusion Assessment Method (CAM) focuses on acute changes in cognition and attention to diagnose delirium.### Myxedema and Hypothyroidism
Myxedema is characterized by swelling and thickening of skin tissue due to mucopolysaccharide deposition.
It represents a severe manifestation of hypothyroidism.

Skin Lesion Morphology

Papule: Small solid elevation of the skin, ≤1 cm in diameter, extending into deeper layers.
Pustule: Small circumscribed elevation filled with purulent fluid.
Vesicle: Small circumscribed elevation containing clear fluid, ≤1 cm in diameter.
Wheal: Circumscribed, raised lesion due to dermal edema; also known as hives or urticaria.
- Characteristics: lasts ~6 mm, elevated, firm to palpation, may grow over weeks.

Melanoma and Skin Cancer Screening

Insufficient evidence exists for the benefits of clinician-performed visual skin examinations by the USPSTF.
Clinical skin examinations within 3 years of melanoma diagnosis lead to thinner melanomas.
At least 50% of melanomas arise from isolated melanocytes, not previous nevi.
Blue or black color in larger lesions raises melanoma concern, except in homogenous blue nevi.
Evolving lesions are the most sensitive criterion for identifying melanoma; history of change may necessitate biopsy.

Patient Screening Recommendations

The American Academy of Dermatology (AAD) and American Cancer Society (ACS) advocate regular skin self-examinations.
High-risk individuals should regularly self-examine, particularly those with:
- History of high sun exposure
- Prior or family history of melanoma
- 50+ moles or >5-10 atypical moles

Skin Conditions and Lesions

Herpes Zoster: Characterized by unilateral dermatomal vesicles.
Herpes Simplex: Presents with grouped vesicles or pustules on an erythematous base.
Tinea Pedis (Athlete’s Foot): Displays annular lesions.
Poison Ivy Dermatitis: Features linear lesions from allergic contact.
Blanchable Lesions: Erythematous, indicating inflammation.
Nonblanching Lesions: Include petechiae, purpura, cherry angiomas; appear bright red or violaceous due to blood extravasation.

Specific Skin Conditions

Psoriasis: Commonly affects scalp, elbows, knees, umbilicus, gluteal cleft.
Lichen Planus: Often arises on wrists, forearms, genitals, lower legs.
Vitiligo: Can be patchy or located around distal extremities, face, particularly near eyes and mouth.
Discoid Lupus Erythematosus: Presents with lesions on sun-exposed areas, especially the face.
Hidradenitis Suppurativa: Involves areas with high apocrine gland density, such as axillae, groin, under breasts.
