Bornholm disease, also known as epidemic pleurodynia, is a condition characterized by myositis of the abdomen or chest caused by the Coxsackie B virus or other viruses. The myositis manifests as an intermittent stabbing pain in the musculature that is seen primarily in children and young adults.
It is named after the Danish island of Bornholm in the Baltic Sea where an outbreak was one of the first to be described.
Signs and symptoms
The expected symptoms of Bornholm disease include fever, pleuritic chest pain, or epigastric abdominal pain that is frequently spasmodic. Bornholm associated chest pain is distinguished by attacks of severe pain in the lower chest, often on the right side. In a prior study, the episodes were shown to last five to ten minutes and then subside for thirty minutes. The pain is exacerbated by movement and makes walking and breathing more difficult. Patients have found relief from the pain by lying still for a brief period of time. The slightest movement of the rib cage causes a sharp increase in pain, which makes it difficult to breathe, although it generally passes off before any actual harm occurs. The attacks are unpredictable and strike "out of the blue" with a feeling like an iron grip around the rib cage. The colloquial names for the disease, such as the devil's grip, (see "other names" below) reflect this symptom. and those findings were supported by subsequent studies of IgM antibody responses measured in serum from people with pleurodynia. Other viruses in the enterovirus family, including echovirus and Coxsackie A virus, are less frequently associated with pleurodynia. Echovirus types 1,6,8,9, and 19 and Coxsackie A virus types 4,6,9, and 10 are associated with Bornholm disease. The most common strains causing Bornholm disease are Coxsackie B3 and A9. Viral proliferation in the muscles of the chest wall, diaphragm, and abdomen are thought to contribute to the typical presentation that characterizes the illness.
Epidemiology
The most common cause of Bornholm disease, Coxsackie B virus, is shed in large amounts in the feces of infected persons and is spread primarily through the fecal-oral route. Respiratory secretions and oral-oral methods have also shown to be modes of transmission. In previous cases the disease has been spread by sharing drink containers, and has been contracted by laboratory personnel working with the virus. Relapses during the weeks following the initial episode are a characteristic feature of this disease. Bornholm disease typically lasts between one day and one week with an average illness duration of four days. In 20% of cases studied, the illness lasted between one and two weeks. The illness in children was found to be shorter than the illness in adults. Patients typically make a complete recovery with supportive care. Although recovering from Bornholm disease is expected, some rare complications include myocarditis, respiratory failure, hepatic necrosis with coagulopathy, and disseminated intravascular coagulopathy (DIC). Aseptic meningitis, pericarditis and pleurisy are also known potential complications of Bornholm disease.
Differential diagnoses
Acute appendicitis, cholecystitis, pancreatitis, pulmonary embolism, acute coronary syndrome, costochondritis, amongst others In 1933, Ejnar Sylvest gave a doctoral thesis describing a Danish outbreak of this disease on Bornholm Island entitled "Bornholm disease-myalgia epidemica", and this name has persisted. In 1949 the Coxsackie B virus was isolated and established as an etiology of Bornholm disease.
