Study Notes

Syncope and Cerebral Blood Flow

  • Symptom: Dizziness, lightheadedness, or a feeling of faintness are common symptoms accompanying insufficient cerebral blood flow during a syncope episode.

Red Flags in Syncope Evaluation

  • Not a Red Flag: Syncope without any associated neurological symptoms like seizures, weakness, or paralysis is typically not considered a red flag.

Varicose Veins

  • Risk Factor: Obesity is a common risk factor for the development of varicose veins.
  • Diagnostic Method: Ultrasound is typically used to assess varicose veins.

Varicose Veins and Valvular Incompetence

  • Not a Symptom: Pulmonary edema is not a symptom of valvular incompetence in varicose veins.

Cortisol and ACTH Levels

  • Low ACTH and High Cortisol: This indicates Cushing's Syndrome, a condition where the adrenal glands produce too much cortisol.

Pituitary Adenoma and Dexamethasone Suppression Test

  • Expected Response: A high-dose dexamethasone suppression test for a pituitary adenoma would show suppressed cortisol levels.

High ACTH and High Cortisol

  • Condition: This combination indicates Cushing's disease, a condition where the pituitary gland produces too much ACTH, leading to excess cortisol production.

Low ACTH and High Cortisol

  • Diagnostic Stop: Confirmation of low ACTH and high cortisol would likely require stopping further diagnostic processes as it strongly suggests Cushing's syndrome, requiring further evaluation and treatment.

Adrenal Adenomas and Cortisol Secretion

  • Cause: Adrenal adenomas are typically the cause of excess cortisol secretion as they produce cortisol independently.

Pulmonary Fibrosis and Surgery

  • Treatment: The treatment for pulmonary fibrosis before surgery involves managing symptoms and optimizing lung function, including medications and pulmonary rehabilitation.

Asthma and COPD in PFTs

  • Distinguishing Factor: Asthma exhibits reversible airflow obstruction, whereas COPD shows irreversible airflow obstruction in PFTs.

Indications for PFTs Prior to Surgery

  • Not an Indication: PFTs are typically not performed before surgery for patients undergoing elective orthopedic procedures.

Methadone and Surgery

  • Action: Patients on methadone undergoing surgery should continue their medication regimen and discuss adjustments with the anesthesiologist.

CAGE Screening Tool for Substance Use Disorder

  • Symptom: Feeling Guilty about drinking is part of the CAGE screening tool.

Risk Factors for Pulmonary Complications in Surgery

  • Parameter: Obesity is a significant risk factor for pulmonary complications in surgery.

Naltrexone and Substance Abuse

  • Role: Naltrexone plays a role in treating substance abuse by blocking the effects of opioids.

Opioid Abuse and Anesthesia

  • Concern: Difficulty achieving and maintaining anesthesia is a concern for patients with opioid abuse.

Cancer Infiltration Complications

  • Most Severe Complication: Bowel obstruction is the most severe complication associated with cancer infiltration into the gastrointestinal tract.

Food and Gastrointestinal Conditions

  • Increased Risk: Excessive consumption of red meat is associated with increased risk factors for certain gastrointestinal conditions.

Pheochromocytoma Triad

  • Classic Triad: Headache, palpitations, and sweating form the classic triad of symptoms associated with pheochromocytoma.

GERD and Symptoms

  • Common Symptom: Heartburn is a common symptom associated with GERD.

Low Cortisol Levels

  • Hormones: LH (luteinizing hormone) and FSH (follicle-stimulating hormone) levels are typically low in conditions leading to low cortisol.

Diagnosing GERD

  • First-Line Intervention: Endoscopy is considered the first-line intervention for diagnosing GERD.

Managing Pheochromocytoma

  • First-Line Treatment: Alpha-blockers are the first-line treatment approach for managing pheochromocytoma.

H2 Receptor Blockers

  • Administration: H2 receptor blockers should be administered to patients with GERD who have frequent heartburn episodes despite lifestyle modifications.

Diagnosing Pheochromocytoma

  • Lab Test: Plasma metanephrines and normetanephrines are useful in diagnosing pheochromocytoma.

Red Flags in GERD

  • Alarm SX: Dysphagia (difficulty swallowing) is considered a red flag symptom in GERD patients.

Symptoms Associated with Pheochromocytoma

  • Not Typically Associated: Hypotension (low blood pressure) is not typically associated with pheochromocytoma.

GERD Predisposing Factors

  • Not a Predisposing Factor: Rheumatoid arthritis is not a known predisposing factor for GERD.

Melena

  • Indication: Melena indicates upper gastrointestinal bleeding in the context of GI bleeding.

Hematemesis

  • Primary Symptom: Vomiting blood is the primary symptom associated with hematemesis.

Ongoing GI Bleeding

  • Crucial Intervention: Endoscopy is crucial for a patient with ongoing GI bleeding to identify the source and stop it.

Medications to Avoid in GERD

  • Avoid: NSAIDs (nonsteroidal anti-inflammatory drugs) should be avoided in patients with GERD as they may worsen symptoms.

Metastasis Sign

  • Sign: Lymph node enlargement is indicative of significant metastasis that may be found during examination.

LES Relaxation and GERD

  • Consequence: Acid reflux is a common consequence of transient relaxation of the lower esophageal sphincter (LES) in GERD.

Cushing's Syndrome Cause

  • Most Common Cause: Pituitary adenomas are the most common cause of Cushing's syndrome.

Cushing's Disease Physical Finding

  • Characteristic Finding: Moon face is a characteristic physical finding associated with Cushing's disease.

Cortisol Suppression Assessment

  • Test: The dexamethasone suppression test is used to assess the suppression of cortisol production.

Treatment for Pituitary Adenoma

  • Treatment: Surgery is the indicated treatment for a pituitary adenoma causing Cushing's disease.

ACTH Independent Cushing's Syndrome

  • Hormone Levels: ACTH-independent Cushing's syndrome is characterized by high cortisol levels but normal or low ACTH levels.

Symptoms of Cushing's Syndrome

  • Not Typically Associated: Hypoglycemia (low blood sugar) is not typically associated with Cushing's syndrome.

Glucocorticoid Management

  • Avoidance: Glucocorticoids should be tapered gradually to avoid adrenal crisis in patients with steroid use.

Macroadenoma

  • Finding: Visual field defects may suggest the presence of a macroadenoma in a patient.
