Review Meta AnalysisInterventions aimed at improving immunization rates.
Immunization rates for children and adults are rising, but coverage levels have not reached national goals. As a result of low immunization rates, vaccine-preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care, and large demands on primary care physicians, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. A common theme across immunization programs in all nations involves the challenge of determining the denominator of eligible recipients (e.g., all children who should receive the measles vaccine), and identifying the best strategy to ensure high vaccination rates. Strategies have focused on patient-oriented interventions (e.g., patient reminders), provider interventions, and system interventions. One intervention strategy involves patient reminder/recall systems. ⋯ Patient reminder/recall systems in primary care settings are effective in improving immunization rates.

: Although the health benefits of breastfeeding are widely acknowledged, opinions and recommendations are strongly divided on the optimal duration of exclusive breastfeeding. Much of the debate has centered on the so-called 'weanling's dilemma' in developing countries: the choice between the known protective effect of exclusive breastfeeding against infectious morbidity and the (theoretical) insufficiency of breast milk alone to satisfy the infant's energy and micronutrient requirements beyond four months of age. The debate over whether to recommend exclusive breastfeeding for four to six months versus 'about six months' has recently become heated and acrimonious. ⋯ : We found no objective evidence of a 'weanling's dilemma'. Infants who are exclusively breastfed for six months experience less morbidity from gastrointestinal infection than those who are mixed breastfed as of three or four months, and no deficits have been demonstrated in growth among infants from either developing or developed countries who are exclusively breastfed for six months or longer. Moreover, the mothers of such infants have more prolonged lactational amenorrhea. Although infants should still be managed individually so that insufficient growth or other adverse outcomes are not ignored and appropriate interventions are provided, the available evidence demonstrates no apparent risks in recommending, as a general policy, exclusive breastfeeding for the first six months of life in both developing and developed country settings. Large randomized trials are recommended in both types of setting to rule out small effects on growth and to confirm the reported health benefits of exclusive breastfeeding for six months or beyond.

ReviewSurgical approaches for inserting hemiarthroplasty of the hip.
The operation of insertion of a hemiarthroplasty to the hip refers to replacement of the femoral head with a prosthesis, whilst retaining the natural acetabulum and acetabular cartilage. The main surgical approaches to the hip for insertion of the prosthesis can be broadly categorised as either 'anterior' via the anterior joint capsule, or 'posterior' through the posterior joint capsule. ⋯ There is currently insufficient evidence from randomised trials to determine the optimum surgical approach for insertion of a hemiarthroplasty to the hip.

The common cold is considered to be caused by viruses and it has long been believed that antibiotics have no role in treating this condition. In many countries doctors will often prescribe antibiotics for the common cold in the belief that they may prevent secondary bacterial infection and in some cases to respond to patient demand. There is also increasing concern over the resistance of common bacteria to commonly used antibiotics. A crucial step in reducing the use of antibiotics for the common cold is to examine the evidence to see if there is any benefit or if there is benefit for some subgroups or symptom constellations. ⋯ There is not enough evidence of important benefits from the treatment of upper respiratory tract infections with antibiotics to warrant their routine use in children or adults and there is a significant increase in adverse effects associated with antibiotic use in adult patients.

Various solutions have been recommended for cleansing wounds, however normal saline is favoured as it is an isotonic solution and does not interfere with the normal healing process. Tap water is commonly used in the community for cleansing wounds because it is easily accessible, efficient and cost effective, however, there is an unresolved debate about its use. ⋯ Although the evidence is limited one trial has suggested that the use of tap water to cleanse acute wounds reduces the infection rate and other trials conclude that there is no difference in the infection and healing rates between wounds that were not cleansed and those cleansed with tap water and other solutions. However the quality of the tap water should be considered prior to its use and in the absence of potable tap water, boiled and cooled water as well as distilled water can be used as wound cleansing agents.
