Chemotherapy agents damage both cancerous and healthy cells, leading to systemic toxicity. Cisplatin causes renal and ototoxicity, while doxorubicin is known for cardiotoxicity.

How it's Diagnosed: videos
Clinical symptoms, laboratory tests (renal function, cardiac markers), audiometry (for hearing loss), and imaging studies (e.g., echocardiogram for cardiotoxicity).

Treatment:
Symptomatic management, dose adjustment or discontinuation of the chemotherapy agent, and supportive measures like hydration for renal protection or use of cardioprotective agents.

Medications:
Medications to mitigate toxicity include amifostine (cytoprotective agent), dexrazoxane (cardioprotective for doxorubicin ), antiemetics like ondansetron , and growth factors like filgrastim to manage neutropenia.

Prevalence: How common the health condition is within a specific population.
Common among patients undergoing chemotherapy; up to 90% may experience some degree of toxicity.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
High cumulative dose, pre-existing kidney or heart conditions, older age, and genetic predisposition.

Treatment:
Discontinuation of NSAIDs, proton pump inhibitors (e.g., omeprazole) for gastric protection, IV fluids for renal support, and treatment of complications like anemia or bleeding.

Medications:
Proton pump inhibitors (e.g., omeprazole ), misoprostol (for gastric mucosal protection), or activated charcoal (in acute overdose).

Prevalence: How common the health condition is within a specific population.
Common; NSAID-related adverse effects are seen in up to 25% of chronic users.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Long-term use, high doses, older age, concurrent anticoagulant or corticosteroid use, and pre-existing kidney or gastrointestinal conditions.

Prognosis: The expected outcome or course of the condition over time.
Good with early management; severe complications like GI perforation or kidney failure can be life-threatening.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Peptic ulcer disease, gastrointestinal perforation, chronic kidney disease, or cardiovascular events.

Specialty: Toxicology

Category: Adverse Effects of Therapeutics and Medical Agents

Sub-category: Drug-Induced Toxicity

Symptoms:
excessive bleeding; bruising; hematuria; melena; intracranial hemorrhage in severe cases

Root Cause:
Over-anticoagulation due to excessive drug dosage or interactions, impairing the coagulation cascade and increasing bleeding risk.

How it's Diagnosed: videos
Clinical evaluation, coagulation tests (INR for warfarin, aPTT for heparin), and imaging for suspected internal bleeding.

Treatment:
Discontinuation of the anticoagulant, administration of reversal agents (e.g., vitamin K for warfarin, protamine sulfate for heparin), and supportive measures like blood transfusions.

Medications:
Vitamin K (phytonadione ) for warfarin reversal, protamine sulfate for heparin reversal, and andexanet alfa for factor Xa inhibitors.

Prevalence: How common the health condition is within a specific population.
Anticoagulant-related adverse events occur in 2-5% of patients annually.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Advanced age, drug interactions, comorbidities like liver disease, and poor adherence to monitoring protocols.

Prognosis: The expected outcome or course of the condition over time.
Favorable with prompt intervention; severe cases can result in fatal bleeding or long-term disability.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Intracranial hemorrhage, hypovolemic shock, and death.

Anesthetic toxicity (e.g., lidocaine, bupivacaine)

Specialty: Toxicology

Category: Adverse Effects of Therapeutics and Medical Agents

Sub-category: Iatrogenic Conditions

Symptoms:
numbness; tingling; seizures; dizziness; difficulty breathing; arrhythmias; cardiovascular collapse; confusion

Root Cause:
Overdose or unintended systemic absorption of local anesthetics leading to central nervous system and cardiovascular toxicity.

How it's Diagnosed: videos
Diagnosis is based on clinical presentation and history of recent local anesthetic administration; blood levels of the anesthetic can confirm toxicity.

Treatment:
Immediate discontinuation of the anesthetic, intravenous lipid emulsion therapy, supportive care (oxygen, airway management, and monitoring), and anticonvulsants for seizures (e.g., benzodiazepines).

Medications:
Medications include intravenous lipid emulsion therapy (as a treatment to counteract toxicity), anticonvulsants like lorazepam or diazepam (sedatives and anticonvulsants), and vasopressors (such as epinephrine) if required for managing cardiovascular symptoms.

Prevalence: How common the health condition is within a specific population.
Rare, but incidence is higher in patients with high doses or when multiple injections are administered, especially in high-risk procedures.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
High doses of local anesthetics, accidental intravenous injection, renal or hepatic insufficiency, prolonged duration of anesthesia, and use of multiple anesthetics simultaneously.

Prognosis: The expected outcome or course of the condition over time.
Typically reversible with appropriate treatment; mortality is rare but possible with delayed or inadequate intervention.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Seizures, cardiovascular collapse, neurological deficits, arrhythmias, and in extreme cases, death.

Radiation therapy-induced toxicity

Specialty: Toxicology

Category: Adverse Effects of Therapeutics and Medical Agents

Sub-category: Iatrogenic Conditions

Symptoms:
skin burns; fatigue; nausea; vomiting; dry mouth; difficulty swallowing; pneumonitis; esophagitis

Root Cause:
The ionizing radiation used in cancer therapy causes damage to normal healthy tissues, leading to acute or chronic inflammation and cellular damage.

How it's Diagnosed: videos
Diagnosis is based on clinical symptoms, timing in relation to radiation therapy, and imaging findings; biopsy or laboratory tests may be used to assess tissue damage.

Treatment:
Management involves corticosteroids, anti-nausea medications, pain relief, and symptomatic management of skin or mucosal irritation. Depending on the affected organ, more specific treatments may be required (e.g., antibiotics for radiation pneumonitis).

Medications:
Corticosteroids (e.g., prednisone , dexamethasone ) are used to reduce inflammation, anti-nausea drugs (e.g., ondansetron ), pain relievers, and sometimes antibiotics or immunosuppressants for more severe reactions.

Prevalence: How common the health condition is within a specific population.
Radiation-induced toxicity is a common complication, though its severity depends on the type and location of radiation therapy.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
High radiation doses, field size, proximity of radiation to critical organs, underlying health conditions (e.g., diabetes, heart disease), and concurrent chemotherapy.

Prognosis: The expected outcome or course of the condition over time.
Most toxicity symptoms resolve after treatment; however, long-term or permanent tissue damage can occur, especially with high doses.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic fatigue, fibrosis, secondary cancers, esophageal stenosis, and pulmonary issues.

Contrast-induced nephropathy (from imaging studies)

Specialty: Toxicology

Category: Adverse Effects of Therapeutics and Medical Agents

Sub-category: Iatrogenic Conditions

Symptoms:
acute kidney dysfunction; decreased urine output; swelling; nausea; vomiting; fatigue

Root Cause:
Contrast agents used in imaging studies can cause kidney damage, typically through direct toxicity to the renal tubular cells or through causing vasoconstriction, reducing blood flow to the kidneys.

How it's Diagnosed: videos
Diagnosis involves assessing kidney function through serum creatinine levels, urine output, and the timing of symptoms in relation to contrast exposure. Imaging may also show signs of kidney damage.

Treatment:
The mainstay of treatment is supportive care, which includes hydration, monitoring kidney function, and possibly using diuretics in some cases. Dialysis may be required in severe cases.

Medications:
N-acetylcysteine (a potential preventive measure), bicarbonate infusions (to alkalinize urine and prevent nephropathy), and diuretics (e.g., furosemide ) may be used if necessary to manage kidney function.

Prevalence: How common the health condition is within a specific population.
Contrast-induced nephropathy occurs in approximately 2-5% of patients exposed to contrast media, though this varies with the population studied and the type of contrast used.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Pre-existing renal disease, dehydration, diabetes, older age, use of high-osmolar contrast agents, and concurrent use of nephrotoxic drugs.

Prognosis: The expected outcome or course of the condition over time.
Most patients recover with appropriate management, but some may develop chronic kidney disease or require dialysis.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic kidney disease, electrolyte imbalances, and in rare cases, kidney failure.
