Reference only, to read alongside your own examination.

Symptoms — what the patient reports (10)

  • Early features include marked fatigue, double vision, drooping eyelids, and trouble swallowing or speaking [difficulty swallowing · double vision · fatigue]
  • Blurred vision from fixed, dilated pupils [blurred vision]
  • No sensory loss is typical, though occasional tingling occurs [tingling]
  • Constipation and urinary retention from smooth-muscle paralysis [constipation · paralysis · urinary retention]
  • Foodborne cases start with abdominal pain, nausea, and vomiting 12 to 72 hours after eating the toxin [abdominal pain · nausea · vomiting]
  • Constipation is an almost universal eventual symptom in foodborne cases [constipation]
  • Infants show early constipation, weakness, feeding trouble, a weak cry, and drooling [constipation · drooling]
  • A floppy, globally hypotonic infant needs immediate intubation and ventilation
  • Wound botulism is the only form presenting with fever and signs of infection [fever]
  • Inhaled botulism may start with an irritating upper-airway prodrome before nerve symptoms appear

Signs — what you find (3)

  • Illness starts with cranial nerve palsies that progress to symmetric descending weakness and eventual flaccid paralysis [paralysis]
  • Weakness is symmetric, without confusion or blood pressure instability
  • Diaphragm weakness can cause respiratory failure needing intubation

Tests (7)

  • Treatment starts on clinical suspicion alone since lab confirmation can take several days
  • EMG or nerve conduction studies can support the diagnosis while lab results are pending
  • EMG may show small evoked action potentials in affected muscles after strong nerve stimulation
  • Electrophysiologic studies can be falsely negative or normal early in the illness
  • Confirmation can use serum and stool toxin assays, gastric aspirates, rectal swabs, or stool and wound cultures
  • Toxin testing traditionally used a mouse bioassay, injecting a sample and watching for signs of illness
  • Several patients with similar symptoms in a short time should raise concern for intentional exposure

If not this — what else fits (7)

  • Guillain-Barre syndrome is a key differential for the descending paralysis
  • Myasthenia gravis or acute intermittent porphyria can mimic the presentation
  • Lambert-Eaton myasthenic syndrome is on the differential
  • Tick paralysis or brainstem cerebrovascular disease can produce a similar picture
  • A basilar artery stroke is considered for acute bulbar weakness
  • Diphtheria and encephalitis are also on the list
  • Hyperthyroidism and thyrotoxicosis are included in the differential

NO DRUG THERAPY IN PRIMARY CARE (EMERGENCY REFERRAL)

1st line
Adult dose and duration

Call emergency services immediately (123) and contact the Egyptian Poison Control Center Hotline (137 / 02-26840902) for urgent transfer to a tertiary poison control center / ICU for Equine Botulinum Antitoxin administration and respiratory monitoring. - Immediate emergency transfer

Paediatric dose

Infant botulism (honey ingestion) or pediatric foodborne botulism requires immediate emergency transport to a pediatric ICU for Human Botulism Immune Globulin (BIG-IV) or antitoxin and airway management.

Dose source

CDC Clinical Guidelines for Diagnosis and Treatment of Botulism, 2021 (MMWR Recomm Rep 2021;70(2); PMC8112830)

Why

Foodborne botulism in Egypt is seasonal and strongly tied to unhygienically prepared salted fish (feseekh) consumed during Sham El-Nessim; early administration of botulinum antitoxin in an ICU before irreversible neuromuscular blockade occurs is life-saving.

Cautions
  • TIME-CRITICAL EMERGENCY: Administer botulinum antitoxin as early as possible after clinical diagnosis; antitoxin neutralizes circulating toxin but cannot reverse established paralysis.
  • CLASSIC PRESENTATION: Symmetrical descending flaccid paralysis with prominent cranial nerve bulbar palsies (diplopia, ptosis, dysarthria, dysphagia, dysphonia) and clear sensorium without fever.
  • RESPIRATORY FAILURE: Rapid respiratory arrest can occur due to diaphragmatic and intercostal muscle paralysis; prepare for immediate airway securing and mechanical ventilation during transport.
  • Do NOT administer aminoglycosides or non-depolarizing neuromuscular blockers as they potentiate botulinum neuromuscular blockade.
