Cervical Ripening and Induction of Labor.

Induction of labor is a common obstetric procedure, and approximately one-fourth of pregnant patients undergo the procedure. Although exercise and nipple stimulation can increase the likelihood of spontaneous labor, sexual intercourse may not be effective. Acupuncture has been used for labor induction; however, it has not been shown to increase vaginal delivery rates. There is strong evidence that membrane sweeping can increase the likelihood of spontaneous labor within 48 hours. Cervical preparation or ripening is often needed before induction. Some evidence shows that the use of nonpharmacologic approaches such as osmotic dilators and cervical ripening balloons reduce time to delivery. The effect of amniotomy on labor is uncertain. Pharmacologic intervention with oxytocin or prostaglandins is effective for cervical ripening and induction of labor. Combining a balloon catheter with misoprostol is a common practice and has been shown to decrease time to delivery in a small study.

Toilet Training: Common Questions and Answers.

Toilet training is a significant developmental milestone in early childhood. Most U.S. children achieve the physiologic, cognitive, and emotional development necessary for toilet training by 18 to 30 months of age. Markers of readiness for toilet training include being able to walk, put on and remove clothing, and follow parental instruction; expressive language; awareness of a full bladder or rectum; and demonstrated dissatisfaction with a soiled diaper. Other readiness cues include imitating toileting behavior, expressing desire to toilet, and demonstrating bladder or bowel control (staying dry through a nap or through the night). Physicians should provide anticipatory guidance to parents beginning at about 18 to 24 months of age, noting the signs of toilet training readiness, and setting realistic expectations for parents. Parents should be counseled that no training method is superior to another. Parents should choose a method that is best suited to them and their child, and the method should use positive reinforcement. Complications of toilet training include stool toileting refusal, stool withholding, encopresis, hiding to defecate, and enuresis. These problems typically resolve with time, although some may require further investigation and treatment. Medical comorbidities such as Down syndrome, autism spectrum disorder, and cerebral palsy reduce the likelihood of successfully attaining full toilet training and often require early consultation with occupational therapists, developmental pediatricians, or other subspecialists to aid in toilet training.

Reducing the dose of smallpox vaccine reduces vaccine-associated morbidity without reducing vaccination success rates or immune responses.

BACKGROUND: When the decision was made to prepare for a deliberate release of smallpox, the United States had approximately 15 million doses of Wyeth Dryvax vaccine, which was known to induce significant morbidity when used undiluted; Sanofi Pasteur, Inc., later identified approximately 85 million additional doses in storage. METHODS: Eleven vaccine-dose groups, each with 30 vaccinia-naive subjects, were given diluted Dryvax vaccine or 1 of 2 lots of Sanofi Pasteur smallpox vaccine and were evaluated for vaccination success rates, morbidity, and immune responses. RESULTS: Estimated doses of 10(6.6)-10(8.2) pfu of virus/mL induced major reactions (or "takes") in 93%-100% of subjects in each dose group. No differences in vaccination take rates, lesion size, erythema, and induration or in serum neutralizing-antibody response were detected between the groups. However, systemic reactogenicity and missed activities were significantly lower for the vaccine groups given doses of 10(6.6)-10(7.2) pfu/mL than for those given doses of 10(7.6)-10(8.2) pfu/mL. CONCLUSIONS: These findings support the use of a higher dilution of Wyeth Dryvax vaccine and Sanofi Pasteur smallpox vaccine, given that the resulting morbidity should be significantly lower without loss of vaccine effectiveness. A plan for use of higher dilutions would create an enormous stockpile of vaccine.

Safety, immunogenicity, and immune memory of a novel meningococcal (groups A, C, Y, and W-135) polysaccharide diphtheria toxoid conjugate vaccine (MCV-4) in healthy adolescents.

OBJECTIVE: A meningococcal (groups A, C, Y, and W-135) polysaccharide diphtheria toxoid conjugate vaccine (MCV-4; Menactra; Sanofi Pasteur Inc, Swiftwater, Pa) was developed to improve the profile of currently licensed products. The objective of this study was to compare the tolerability, immunogenicity, and immune memory of MCV-4 with those of a quadrivalent polysaccharide vaccine (PSV-4; Menomune A/C/Y/W-135; Sanofi Pasteur Inc). DESIGN, SETTING, PARTICIPANTS: A randomized, double-blind trial was performed at 11 clinical centers in the United States. The vaccine MCV-4 or PSV-4 was administered to 881 healthy 11- to 18-year-olds. Sera were collected prevaccination and 28 days postvaccination. Three-year follow-up and booster vaccination with MCV-4 were performed in a participant subset from each group and a control group. MAIN OUTCOME MEASURES: Proportion of participants with a 4-fold or greater increase in serum bactericidal antibody against each serogroup 28 days after initial vaccination, geometric mean serum bactericidal antibody titers, and safety assessments. RESULTS: Both vaccines were well tolerated; most reactions were mild. More MCV-4 recipients reported solicited local reactions (68.9%) than PSV-4 recipients (30.2%). Both MCV-4 and PSV-4 were highly immunogenic; similar proportions of participants had 4-fold or greater increases in serum bactericidal antibody (range, 80.1%-96.7%) to the 4 serogroups. Three-year follow-up showed persistence of serum bactericidal antibody and booster responses to MCV-4 consistent with immune memory in participants previously vaccinated with MCV-4, but not in those who had previously received PSV-4. CONCLUSIONS: The vaccine MCV-4 was well tolerated and highly immunogenic. Persistence of bactericidal activity with MCV-4, but not PSV-4, was evident 3 years after the initial immunization. Booster response was demonstrated after a second vaccination with MCV-4.
