This study was undertaken to compare prospectively the frequency, nature, and severity of infections experienced by children in three types of child care arrangements: home care, group care (two to six children), and day care (seven or more children). Children were enrolled at birth and observed for 12 to 18 months. At entry there were 159 children in home(More)
This study was performed to determine the usual duration of community-acquired viral upper respiratory tract infections and the incidence of complications (otitis media/sinusitis) of these respiratory tract infections in infancy and early childhood. Children in various forms of child-care arrangements (home care, group care, and day care) were enrolled at(More)
Acute rheumatic fever is reported to have declined and perhaps be vanishing. Prompted by the occurrence of 17 cases of acute rheumatic fever in an 18-month period in 1985 and 1986, we reviewed the records of 243 children with acute rheumatic fever who were cared for at Children's Hospital of Pittsburgh or Mercy Hospital between 1965 and 1986. Acute(More)
Duplicate vaginal swabs were obtained from patients who attended obstetric or gynecologic clinics affiliated with the Magee Womens Hospital in Pittsburgh. One swab was cultured semiquantitatively on 5% sheep blood agar to detect group B streptococci (GBS). The other swab was subjected to a rapid method (25 min) for antigen detection and micronitrous acid(More)
This study was undertaken to compare prospectively the frequency, nature, and severity of infections in children participating in three types of child care arrangements: home care, group care (two to six children), and day care (seven or more children). Children were enrolled at birth and observed for at least 36 months. The families were telephoned every 2(More)
The bacteriologic characteristics of subacute maxillary sinusitis have not been delineated in the pediatric age group. Forty children between the ages of 2 and 12 years with respiratory symptoms for at least 30 but less than 120 days were evaluated. Nasal discharge and cough were the most prominent symptoms. Common radiographic findings were diffuse(More)
This study compared the relative effectiveness of a standard pancreatic enzyme supplement ('Creon', Duphar) and a new preparation ('Pancrease HL', Cilag) containing about 3 times the lipase and more than 5 times the protease activity. Capsule dosage was adjusted to a ratio of approximately 3:1. Fat balances showed that absorption of fat did not change(More)
In 1985, the first capsular polysaccharide (polyribosylribitol-phosphate [PRP]) vaccine for Haemophilus influenzae type b was licensed and recommended for routine use in children between 24 and 60 months of age. In the United States, approximately 75% to 90% of invasive disease due to H influenzae type b occurs in infants younger than 24 months, a(More)
We report a novel solution to a problem of repeated catheter migration that may aid others caring for patients with catheter migration problems. Catheter migration is a frequently reported complication of intrathecal drug delivery systems. We report on an ambulatory patient with a baclofen pump for control of spasticity due to cerebral palsy and dystonia;(More)
Approximately 95% of patients in Northern Europe are pancreatic insufficient due to an inadequacy of their own pancreatic enzyme secretions (Littlewood et al, 2006). These patients need to take pancreatic enzyme replacement therapy (PERT) in order to prevent the symptoms of fat malabsorption. These symptoms include frequent pale, oily and offensive stools,(More)
