1/151. Coxsackievirus B4 as a cause of adult chorioretinitis. PURPOSE: To describe the clinical manifestation and course of chorioretinitis presumed to be secondary to coxsackievirus infection in an adult. METHOD: Case report documented by fundus photography and fluorescein angiography. RESULTS: Ophthalmoscopic examination of a symptomatic 34-year-old woman showed several cream-colored parafoveal spots at the level of the retinal pigment epithelium and similar, multiple confluent spots in the midperiphery of both eyes. Titers for coxsackievirus B4 demonstrated a fourfold rise between acute and convalescent sera. CONCLUSION: Coxsackievirus B4 is apparently a rare cause of chorioretinitis but nevertheless should be considered in the appropriate clinical setting. ( info) |
2/151. The successful containment of coxsackie B4 infection in a neonatal unit. This report describes the containment of a potential enterovirus epidemic in a neonatal intensive care unit. A case of neonatal enterovirus meningitis and myocarditis was identified. Polymerase chain reaction (PCR) was used to assist in appropriate cohorting of contacts. One further infant became cross-infected with Coxsackie B4. serum PCR was accurate in detecting the infection in the early stages in this asymptomatic neonate. Neonatal enterovirus infection is relatively rare but has the potential to cause outbreaks in neonatal wards. PCR can be used to diagnose and monitor for cross infection. ( info) |
3/151. Hydrocution in a case of Coxsackie virus infection. An apparently healthy 7-year-old boy attempted to demonstrate his ability to dive into a whirlpool but was retrieved from the water in a state of unconsciousness after several minutes. resuscitation was unsuccessful. No characteristic signs of drowning were found at the autopsy but examination of the lymph nodes and the cardiac muscle indicated a pre-existent infection. The histological examination revealed a slight degree of predominantly lymphocytic infiltration of the cardiac muscle. IgM antibodies against Coxsackie virus were detected in the serum sample by means of ELISA. The reverse transcriptase polymerase chain reaction (RT-PCR) performed on an extract of formalin-fixed, paraffin-embedded cardiac muscle tissue revealed a dna sequence specific for Coxsackie B3 virus. Therefore, cardiac failure was due to a myocardial virus infection and the additional strain caused by diving. This case report emphasizes the importance of modern molecular biological methods in cases of sudden death including death by hydrocution. ( info) |
4/151. An alcoholic man with an abnormal pulse. A 47-year-old man who smelled of alcohol presented with a three-day history of sore throat. He had not had fever, nausea, vomiting, diarrhea, rhinorrhea, cough, chest pain, or palpitations. On evaluation in the emergency department, he was found to have tachycardia and an irregular pulse.

5/151. hand, foot, and mouth disease. hand, foot, and mouth disease, also known as vesicular stomatitis with exanthem, is a vesicular disorder affecting both skin and oral mucosa. The disease is usually caused by Coxsackie virus A-16 and affects mainly children. The oral lesions may require differential diagnosis from other conditions, such as herpetic gingivostomatitis, aphthous stomatitis, and herpangina. hand, foot, and mouth disease should not be confused with foot-and-mouth disease of cattle, which is rare in human beings and is not caused by Coxsackie virus.

6/151. Treatment of neonatal infection caused by coxsackievirus B3. Four male infants with early neonatal infection caused by coxsackievirus B3 (presumed in one case) exhibited severe thrombocytopenia and liver dysfunction at presentation. The three infants who were administered human normal immunoglobulin within 3 days of disease onset survived, while the fourth infant, who received the preparation 6 days after disease onset, died.

7/151. Viral myocarditis presenting with seizure and electrocardiographic findings of acute myocardial infarction in a 14-month-old child. Acute viral myocarditis is an uncommon but potentially fatal illness in children. patients with myocarditis may present with nonspecific symptoms or atypical findings that make diagnosis in the emergency department difficult. We describe a previously healthy 14-month-old child with difficulty breathing and a tonic-clonic seizure who was subsequently found to have ECG changes and cardiac marker elevation consistent with acute myocardial infarction. The patient was immediately transferred from our community hospital ED to our tertiary care children's hospital. Shortly after admission, the patient developed intractable nonperfusing ventricular arrhythmias necessitating extracorporeal membrane oxygenation. Cardiac function did not recover, and the patient required heart transplantation before cessation of bypass. serology and anatomic pathology confirmed coxsackievirus B myocarditis. This case illustrates (1) the nonspecific presentation of myocarditis as dyspnea and seizure, (2) the manner in which myocarditis can mimic myocardial infarction, and (3) the importance of early diagnosis in the ED and transfer to a tertiary care facility.

8/151. Progressive liver calcifications in neonatal coxsackievirus infection. Coxsackievirus group B can cause a severe systemic disease in the perinatal period. Severe manifestations like meningitis, encephalitis, hepatitis, and myocarditis have been previously reported. A case of a twin neonate infected by coxsackievirus group B is described, who developed progressive extensive hepatic calcifications demonstrated by ultrasound and computed tomography with follow-up. Hepatic calcifications in coxsackievirus infection have not been previously reported. ( info) |
| Several lines of evidence have shown that viral infections are capable of causing coronary spasm and precipitating or mimicking clinical myocardial infarction. Here we report the case of a 41-year-old woman with recurrent angina who was admitted to our hospital because of ventricular tachycardia. Laboratory examination revealed positive IgM titers against Coxsackie B virus. coronary angiography showed normal coronary arteries, but following a cold pressure test severe spasm of all coronaries with thrombotic occlusion of the second marginal branch of the circumflex artery occurred. We conclude that coronary spasm should be clinically suspected in patients with chest pain and ventricular arrhythmia in combination with IgM antibodies against Coxsackie B virus. In these patients, a cold pressure test should be avoided, and antithrombotic and antispastic therapy is recommended. ( info) |
10/151. Congenital skin lesions caused by intrauterine infection with coxsackievirus B3. BACKGROUND: Serious neonatal coxsackievirus infections transplacentally acquired in late pregnancy involve primarily the central nervous system, heart, liver and rarely the skin. patients AND methods: A boy born with a disseminated papulovesicular, nodular, bullous and necrotic ulcerated rash at 39 weeks gestational age developed pneumonia, carditis and hepatitis during the first days after birth. Molecular biological and serological methods were used for virological diagnosis. RESULTS: Coxsackievirus B3 (CVB3) was found in throat swabs and/or feces of the neonate and his mother. In addition, there was serological evidence of intrauterine infection. CONCLUSION: Intrauterine transmission of CVB3 during late pregnancy may lead to varicella-like congenital skin lesions. ( info) |
