Alcohol Withdrawal Syndrome
Specialty: Toxicology
Category: Acute Poisoning
Sub-category: Alcohol-Related Toxicity
Symptoms:
tremors; sweating; anxiety; nausea; vomiting; seizures; hallucinations; delirium tremens
Root Cause:
Sudden cessation or reduction of chronic alcohol consumption leading to central nervous system hyperactivity due to downregulated GABA and upregulated glutamate pathways.
How it's Diagnosed: videos
Clinical history, assessment using tools like the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale, and ruling out other causes of symptoms.
Treatment:
Benzodiazepines (e.g., diazepam, lorazepam), thiamine to prevent Wernicke’s encephalopathy, and supportive care.
Medications:
Diazepam or lorazepam (benzodiazepines) are first-line treatments to control withdrawal symptoms and prevent seizures. Thiamine (vitamin B1) is used to prevent neurological complications.
Prevalence:
How common the health condition is within a specific population.
Occurs in approximately 50% of individuals with chronic alcohol use disorder who suddenly stop drinking. Severe forms (delirium tremens) occur in about 5%.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Chronic alcohol use, history of withdrawal seizures, concurrent illness, electrolyte imbalances, malnutrition.
Prognosis:
The expected outcome or course of the condition over time.

Arsenic Poisoning
Specialty: Toxicology
Category: Chronic Toxicity and Long-Term Exposures
Sub-category: Heavy Metal Toxicity
Symptoms:
nausea; vomiting; abdominal pain; diarrhea; darkened skin patches; thickened skin on palms and soles; fatigue; peripheral neuropathy; confusion; muscle cramps
Root Cause:
Accumulation of arsenic in the body due to exposure to contaminated drinking water, industrial processes, or arsenic-containing pesticides. Arsenic disrupts cellular metabolism, DNA repair, and oxidative processes.
How it's Diagnosed: videos
Diagnosis is made through urine arsenic levels (preferred for recent exposure) or hair and nail analysis for chronic exposure. Clinical symptoms and exposure history are also key.
Treatment:
Treatment includes cessation of exposure, supportive care for symptoms, and chelation therapy for severe cases. Ensuring access to safe water sources is critical.
Medications:
Chelating agents such as dimercaprol and succimer (DMSA) are used to bind arsenic and enhance excretion. The choice of medication depends on the severity of poisoning.
Prevalence:
How common the health condition is within a specific population.
Arsenic poisoning is prevalent in regions with contaminated groundwater, particularly in South Asia (e.g., Bangladesh, India) and parts of South America.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Drinking arsenic-contaminated water, occupational exposure (e.g., smelting, mining), use of arsenic-based pesticides, and ingestion of contaminated food.
Prognosis:
The expected outcome or course of the condition over time.
Early intervention and cessation of exposure can lead to symptom improvement. However, prolonged exposure can result in irreversible damage and increased cancer risk.
Complications:
Additional problems or conditions that may arise as a result of the original condition.

nausea; vomiting; abdominal pain; diarrhea; shortness of breath; cough; weakness; bone pain; renal dysfunction (proteinuria); osteomalacia
Root Cause:
Cadmium exposure occurs primarily through inhalation of fumes or dust (e.g., in industrial settings) or ingestion of contaminated food or water. Cadmium accumulates in the kidneys and bones, leading to oxidative stress, cellular damage, and impaired calcium metabolism.
How it's Diagnosed: videos
Diagnosis is made by measuring cadmium levels in blood or urine. Renal function tests (e.g., urinary protein levels) and bone density studies are often conducted to assess long-term damage.
Treatment:
Treatment includes removing the source of cadmium exposure, supportive care for symptoms, and chelation therapy in severe cases. Calcium and vitamin D supplementation may be recommended for bone health.
Medications:
Chelating agents like dimercaprol and EDTA (ethylenediaminetetraacetic acid) may be used in cases of severe poisoning. Chelation is less effective for chronic exposure due to cadmium's strong tissue binding.
Prevalence:
How common the health condition is within a specific population.
Cadmium poisoning is more common in industrial workers (e.g., battery manufacturing, metal plating) and populations exposed to contaminated food or water, particularly in areas with poor environmental regulations.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Occupational exposure (e.g., smelting, welding), smoking (tobacco contains cadmium), consumption of cadmium-contaminated food (e.g., rice, shellfish), and living near industrial sites.
Prognosis:
The expected outcome or course of the condition over time.
Early removal from exposure can improve outcomes, but chronic exposure may result in irreversible kidney damage, bone demineralization, and other complications.
Complications:
Additional problems or conditions that may arise as a result of the original condition.

Diagnosis is based on the history of exposure to marine creatures, clinical presentation, and identification of the specific venomous species involved.
Treatment:
Treatment includes immediate first aid (e.g., rinsing with vinegar for jellyfish stings, immersion in hot water), pain relief, and administration of specific antivenoms or supportive care. In some cases, defibrillation or respiratory support may be required.
Medications:
Jellyfish stings may be treated with analgesics (NSAIDs or acetaminophen ) for pain. For severe envenomations, antivenom may be administered. Other medications could include corticosteroids to reduce inflammation, and calcium gluconate for specific marine toxins like stonefish venom. Muscle relaxants and antiarrhythmics may be used for severe systemic effects.
Prevalence:
How common the health condition is within a specific population.
Marine envenomations are common in coastal areas, with jellyfish stings alone resulting in millions of cases annually, especially in tropical regions.

Prognosis:
The expected outcome or course of the condition over time.
The prognosis depends on the species involved and the severity of the envenomation. Most cases are mild, but severe reactions can cause long-term complications or be fatal.
Complications:

Nitrate/Nitrite Poisoning (Blue Baby Syndrome)
Specialty: Toxicology
Category: Toxic Effects of Environmental Pollutants
Sub-category: Water Contaminants
Symptoms:
