Use of complementary and alternative medicine by parents of children with HIV infection and asthma and well children.

OBJECTIVE: Although the use of complementary and alternative medicine (CAM) in children is increasing, little is known about its use in children with human immunodeficiency virus (HIV) infection. This study investigated the use of CAM by parents of children with HIV infection (H), children with asthma (A), and well children (W). Our hypothesis was that parents of the H group are more likely to use CAM than parents of the W or A group because of the nature and severity of the illness. MATERIALS AND METHODS: Parents of 152 subjects [H (n = 46), A (n = 53), and W (n = 53)] were interviewed on the use of CAM for their children, types of CAM, reasons for use/nonuse, methods of payment, and perceived benefits for their children. RESULTS: Compared with parents of the W and A groups, parents of the H group were less likely to be employed, were less likely to have private insurance, were less likely to have a high school or college education, and were more likely to be black. Interestingly, 38% of the W parents used CAM in their children compared with 22% in the H group and 25% in the A group. More than 80% of all three groups paid out of pocket for their use of CAM in their children. Within these groups, H parents were more likely to want CAM as part of their child's medical care (H = 91% vs W = 75% and A = 67%, P = 0.02) and were more likely to believe that CAM was expensive (H = 78% vs W = 57% and A = 60%, P < 0.01). CONCLUSIONS: Our study revealed a relatively high rate of CAM usage by parents of all three study groups. Although parents of children with HIV infection were more likely to want CAM as part of their children's medical care, their rate of CAM usage was not higher than that in well children. This may be related to their socioeconomic factors. A larger and more diverse study population may provide more information on factors contributing to CAM usage in chronically ill and well children.

Antibacterial resistance.

Resistance to antimicrobial agents, which was recognized more than 50 years, continues to be a major cause of increased morbidity, mortality and health care cost. Overuse of antibiotics is considered the major contributing factor; however, poor implementation of infection control measures, prolonged hospitalization, admission to intensive care units and the use of invasive procedures are other contributing factors. The authors review the epidemiology, mechanism of resistance, treatment options and prevention measures of infections caused multi-drug resistant S. pneumoniae, methicillin-resistant S. aureus (MRSA), macrolide-resistant S. pyogenes and vancomycin-resistant enterococci (VRE) in pediatric patients. Antibacterial resistance among Gram-negative organisms, including extended spectrum beta-lactamase (ESBL) producing enteric bacteria, and the management and prevention of infections caused by these organisms are also discussed.

Severe cytomegalovirus enterocolitis in an immunocompetent infant.

Gastrointestinal cytomegalovirus infection is a common opportunistic infection in immunocompromised patients. It is a rare cause of enterocolitis in immunocompetent hosts. We present a case of severe cytomegalovirus enterocolitis causing intractable diarrhea in a previously healthy infant. The child was successfully treated with intravenous ganciclovir.

Vancomycin-resistant Enterococcus faecium endocarditis in a premature infant successfully treated with linezolid.

A 4 1/2-month-old, 26-week premature infant with multiple complications of prematurity required a central venous catheter for venous access and antibiotic treatment of bacterial nosocomial infections. He developed tricuspid valve endocarditis with vegetation caused by Enterococcus faecium resistant to ampicillin, vancomycin and quinupristin-dalfopristin but susceptible to linezolid. He was successfully treated with linezolid intravenously (7 weeks) and then orally (2 weeks).

Staphylococcal acalculous cholecystitis in a child.

Acute acalculous cholecystitis is inflammation of the gallbladder in the absence of gallstones. It usually occurs in critically ill patients and is rare in the pediatric age group. We describe a 12-year-old boy who presented with fever, jaundice, and abdominal pain and was found to have acute acalculous cholecystitis, sacroiliitis, and pelvic osteomyelitis associated with bacteremia as a result of Staphylococcus aureus. Antibiotic therapy without surgical intervention was effective. A high index of suspicion is required to make an early diagnosis and institute appropriate treatment for children with this condition. Although cholecystectomy has been considered the standard therapy, medical treatment alone can be successful.
