To identify putative persistent bovine respiratory syncytial virus (BRSV) infections in cattle, seven cattle that had experienced BRSV infections were treated with corticosteroids for two periods of 5 days. During the 5-day periods and the 3 weeks after treatment, attempts were made to isolate BRSV from lung lavage fluid and nasal swab specimens.(More)
BACKGROUND Sydenham chorea (SC), a major sign of rheumatic fever (RF), is related to systemic streptococcal infection and is treated with antibiotics. Recurrence usually occurs within a short interval following the initial event and is considered part of RF. OBJECTIVE To evaluate the rate, nature, and course of recurrent SC during an extended follow-up(More)
Extracorporeal photopheresis (ECP) is beneficial in patients with T-cell-mediated disorders, including GvHD, but the underlying immunological mechanisms are incompletely understood. Myeloid-derived suppressor cells (MDSCs) are innate immune cells characterized by their capacity to suppress T-cell proliferation. We quantified MDSCs by flow cytometry in(More)
To study the epidemiology of respiratory syncytial virus (RSV) infections during the year, the incidences of primary infections and reinfections were monitored by titrating antibodies to bovine RSV (BRSV) in cattle above 2 months of age in 6 dairy herds in the Netherlands. From August 1990 until September 1991, 884 cattle were sampled at one-month(More)
To determine the prevalence of valvular regurgitation in children (from birth to 14 years old) with structurally normal hearts, the records of 1360 consecutive patients referred for echocardiographic and Doppler examination were analyzed. A total of 461 (33.9%) patients were found to have structurally normal hearts. Flow patterns across the four valves were(More)
Atrial septum aneurysm (ASA), usually involving the region of the fossa ovalis, has rarely been described in children. In this study, the incidence and natural course of this anomaly were prospectively evaluated in 3,500 children referred for echocardiographic examination. ASA was found in 35 patients, 19 female and 16 male (1.0%). Patients were 6 years of(More)
Progressive systemic sclerosis sine scleroderma, as well as neurological manifestations of progressive systemic sclerosis are rare in adult-onset cases. Neither have been reported in children with progressive systemic sclerosis, either separately or together. We describe a six-year-old girl with nocturnal seizures and Raynaud's phenomenon of three years'(More)
A seven-year-old girl, stung by a scorpion, was hospitalized in a confused state with signs of myocarditis and pulmonary edema. In spite of clinical improvement within 24 h, 14 serial echocardiograms and electrocardiograms performed during a four-month period showed severe changes. There have been no previously published reports of echocardiographic studies(More)
Treatment of twins each with one impacted maxillary central incisor and a mesiodens is described. Treatment included rapid expansion, extraction of the mesiodens, surgical exposure of the impacted central incisor, and its forced eruption. The impacted incisor was brought into functional position in one patient but was lost in the other because of(More)
