[Clinical analysis of paralytic shellfish poisoning following ingestion of oysters].
We describe five patients of paralytic shellfish poisoning (PSP) following ingestion of oysters in January 1991, in Nagato, Yamaguchi. The five patients (four men and one woman, age range:37-80 years) developed symptoms three-nine hours after consuming oysters. Symptoms included paresthesia of the mouth and tongue (three), paresthesia of the extremities (five), and quadriparesis (five). The median duration of neurological symptoms was 16 hours. All five patients completely recovered. Although PSP is rare as compared with globe fish poisoning in Japan, the fatality rate of PSP is 8%-9%, with deaths occurring in one-12 hours secondary to respiratory failure. PSP is an important disorder for differential diagnosis of acute paralytic illnesses, such as globe fish poisoning, botulism, acute polyradiculoneuropathy, fisher syndrome, myasthenia gravis, and periodic paralysis.
