Non-multiresistant and multiresistant methicillin-resistant Staphylococcus aureus in community-acquired infections.

OBJECTIVE: To survey Staphylococcus aureus strains isolated from patients presenting from the community, comparing clinical features and antibiotic sensitivity profiles between multiresistant and non-multiresistant methicillin-resistant and methicillin-sensitive isolates. DESIGN: Retrospective case series. PARTICIPANTS AND SETTING: Patients who presented to emergency or dermatology departments in hospitals served by the South Western Sydney Area Health Service between 1 May 1998 and 30 April 1999. All patients with methicillin-resistant S. aureus (MRSA) and the first 100 with methicillin-sensitive S. aureus were eligible. MAIN OUTCOME MEASURES: Patient demographic characteristics; risk factors; clinical presentation; treatment; outcome; and isolate antibiotic susceptibility. RESULTS: 139 patients were eligible, and 122 had clinical records available. Ten of these 122 (8%) had multiresistant MRSA, 26 (21%) non-multiresistant MRSA and 86 (70%) methicillin-sensitive S. aureus. Among patients with non-multiresistant MRSA, 29% (7/24) were born in New Zealand, Samoa or Tonga, a higher proportion than among those with multiresistant MRSA or methicillin-sensitive S. aureus (P= 0.03). Nearly half (44%) of non-multiresistant MRSA strains were community-acquired in patients with no risk factors. Two-thirds of patients with non-multiresistant MRSA (17/26) presented with cellulitis or abscess, and 58% (11/19 evaluable patients) required surgical treatment. CONCLUSIONS: Non-multiresistant MRSA strains are common, especially among people born in New Zealand, Samoa or Tonga, and are usually community acquired. Medical practitioners should routinely swab all staphylococcal lesions for culture and sensitivity.

Effectiveness of ARI control strategy on underfive mortality.

A prospective intervention study was conducted in Ballabgarh block of Haryana. The study area has a population of about 30,000 under a state run P.H.C. area. The control area has a population of about 60,000 under Comprehensive Rural Health Services Project of All India Institute of Medical Sciences. ARI control strategies as advocated by WHO was instituted in the study area. Measles and DPT immunization was strengthened. The ARI cases detected or reported to Health Workers were managed as per the standard case management procedure. The underfives mortality, infant and 1-4 years mortality rates were initially higher in study area and differences were statistically significant. After 2 years, the reductions in study area were substantial and differences were not statistically significant. The ARI mortality in underfives, and 1-4 years were higher in study area at the beginning compared to control area. Though they were less than in control area after 2 years of intervention the observed differences were not statistically significant in both periods. The reduction of 37% in underfives mortality and 26% due ARI mortality is substantial. More benefit was attained with measles immunization than with standard case management. ARI control programme is advocated for application on national level vigourously covering with measles immunization and to include the village based private practitioners in the strategy for effective case management.

Development of advanced practice nurses in South Korea.

In Korea, since the first specialized areas of nursing were first recognized in 1973, 10 areas have been established by the Medicine Law, 2003: public health, anesthesia, mental health, home care nursing, gerontological nursing, critical care nursing, industrial nursing, hospice, emergency nursing, and infection control. Education for advanced practice nurses is the MSN level curriculum requiring 33 credit semester hours or more. However, there are several problems to be solved and challenges to be overcome before offering advanced nursing practice to the population. Those tasks and their plausible solutions were discussed in the article.

Angiotensin converting enzyme inhibitor associated cough: a population-based case-control study.

The objectives of this study were to determine the risk for coughing as an adverse reaction to angiotensin converting enzyme (ACE) inhibitors under everyday circumstances in a large population and to study whether this adverse effect is more common in women. A population-based case-control study was used. The study was set in the practices of 161 Dutch general practitioners (GPs), in which all consultations, morbidity, mortality, medical interventions and prescriptions were registered during 4 consecutive 3-month periods in 4 consecutive groups of 40-41 GPs. The subjects were 2436 patients with incident coughing and up to 3 controls per case were obtained (total group: 7348 controls), matched for GP and a contemporary consultation in the same 3 months. All cases and controls were 20 years or older and had no notification of respiratory infections, influenza, tuberculosis, asthma, chronic bronchitis, emphysema, congestive heart failure, sinusitis, laryngitis, haemoptysis or respiratory neoplasms during the 3-month period. The results showed that cases were 3.6 times as likely as controls to have been exposed to ACE inhibitors (95% CI: 2.4-5.5) but after adjustment for potential confounders the odds ratio was 2.5 (95% CI: 1.6-3.9). The crude odds ratio for males was 2.7 (95% CI: 1.4-5.1) and for females 4.2 (95% CI: 2.4-7.5). The adjusted odds ratio for males was 1.8 (95% CI: 0.9-3.5) and for females 2.7 (95% CI: 1.5-4.8).(ABSTRACT TRUNCATED AT 250 WORDS)

Prevention of perinatal group B streptococcal disease: a public health perspective. Centers for Disease Control and Prevention.

Group B streptococcus is a leading cause of serious neonatal infection. Most neonatal GBS infections can be prevented through the use of intrapartum antimicrobial prophylaxis in women who are at increased risk for transmitting the infection to their newborns. However, despite clinical trials that demonstrate the effectiveness of intrapartum antibiotic prophylaxis, prevention strategies have not been implemented widely or consistently, and the incidence of neonatal GBS disease has not declined. To promote a coordinated approach to prevention among obstetric- and pediatric-care practitioners and among supporting clinical microbiology laboratory personnel, CDC has developed prevention guidelines in conjunction with experts from relevant disciplines and with representatives of the American College of Obstetricians and Gynecologists, the American Academy of Pediatrics, and other professional organizations. This report provides the epidemiologic basis for prevention protocols, summarizes results of clinical trials demonstrating the efficacy of intrapartum antimicrobial agents, examines limitations of different approaches to prevention, and presents guidelines for the prevention of GBS disease. CDC recommends use of one of two prevention strategies. In the first strategy, intrapartum antibiotic prophylaxis is offered to women identified as GBS carriers through prenatal screening cultures collected at 35-37 weeks' gestation and to women who develop premature onset of labor or rupture of membranes at < 37 weeks' gestation. In the second strategy, intrapartum antibiotic prophylaxis is provided to women who develop one or more risk conditions at the time of labor or membrane rupture. Issues addressed by these prevention guidelines include the following: the appropriate clinical and laboratory methods required for prenatal screening programs designed to identify GBS carriers; risk conditions that indicate the need for intrapartum antibiotics; management of newborns whose mothers receive intrapartum antibiotic prophylaxis for GBS disease; and education of prenatal patients regarding GBS disease and the available prevention policy. These guidelines are intended for the following groups: a) providers of prenatal, obstetric, and pediatric care; b) supporting microbiology laboratories, hospital administrators, and managed-care organizations; c) childbirth educators; d) public health authorities; e) expectant parents; and f) advocacy groups for expectant parents.

The potential impact of the next influenza pandemic on a national primary care medical workforce.

BACKGROUND: Another influenza pandemic is all but inevitable. We estimated its potential impact on the primary care medical workforce in New Zealand, so that planning could mitigate the disruption from the pandemic and similar challenges. METHODS: The model in the "FluAid" software (Centers for Disease Control and Prevention, CDC, Atlanta) was applied to the New Zealand primary care medical workforce (i.e., general practitioners). RESULTS: At its peak (week 4) the pandemic would lead to 1.2% to 2.7% loss of medical work time, using conservative baseline assumptions. Most workdays (88%) would be lost due to illness, followed by hospitalisation (8%), and then premature death (4%). Inputs for a "more severe" scenario included greater health effects and time spent caring for sick relatives. For this scenario, 9% of medical workdays would be lost in the peak week, and 3% over a more compressed six-week period of the first pandemic wave. As with the base case, most (64%) of lost workdays would be due to illness, followed by caring for others (31%), hospitalisation (4%), and then premature death (1%). CONCLUSION: Preparedness planning for future influenza pandemics must consider the impact on this medical workforce and incorporate strategies to minimise this impact, including infection control measures, well-designed protocols, and improved health sector surge capacity.

The risk of needlestick injuries and needlestick-transmitted diseases in the practice of anesthesiology.

Anesthesiologists are at risk for acquiring blood-borne infections through contact with blood or body fluids. From prospective studies, the greatest risk of transmission is through a percutaneous exposure such as needlestick injury. Personal protective equipment such as gloves and gowns do not completely prevent these exposures. Although educational efforts can reduce the frequency of recapping of needles, they generally have not decreased the incidence of needlesticks. Therefore, in addition to practicing universal precautions, anesthesiologists can attempt to reduce their risk of needlestick injuries by eliminating nonessential unprotected needle use, through the use of needleless or protected needle devices (engineering controls) and by modifying anesthetic procedures requiring needles (work practice controls). Needleless or protected needle products are commercially available for use in many procedures performed by anesthesiologists. For tasks that require the use of needled devices, the practitioner should use safe techniques for handling (i.e., one-handed recapping if recapping is needed) and disposal (i.e., puncture-resistant containers) of these devices. Evaluation of the efficacy, cost, and safety of needleless or protected needle products should be continued as they are introduced into wider use. Additionally, anesthesiologists should be encouraged to report needlestick injuries so that appropriate postexposure treatment can be given and so that the incident can be studied to permit design of a work protocol or device to prevent similar accidents in the future.

Statistical process control as a tool for research and healthcare improvement.

Improvement of health care requires making changes in processes of care and service delivery. Although process performance is measured to determine if these changes are having the desired beneficial effects, this analysis is complicated by the existence of natural variation-that is, repeated measurements naturally yield different values and, even if nothing was done, a subsequent measurement might seem to indicate a better or worse performance. Traditional statistical analysis methods account for natural variation but require aggregation of measurements over time, which can delay decision making. Statistical process control (SPC) is a branch of statistics that combines rigorous time series analysis methods with graphical presentation of data, often yielding insights into the data more quickly and in a way more understandable to lay decision makers. SPC and its primary tool-the control chart-provide researchers and practitioners with a method of better understanding and communicating data from healthcare improvement efforts. This paper provides an overview of SPC and several practical examples of the healthcare applications of control charts.

[Epidemiological characteristics of severe acute respiratory syndrome in Tianjin and the assessment of effectiveness on measures of control].

OBJECTIVE: To analyze the epidemiologic characteristics of severe acute respiratory syndrome (SARS) and to evaluate the effectiveness on its major control measures in Tianjn. METHODS: Adopting two case reports 1 and 2, designed by the Tianjin Centers for Disease Control and Prevention to develop a unified case-tracing table including the map of the distribution of close contacts to SARS patients. With those methods, investigation on patients and their close contacts at hospital wards, families, communities and institutions of the patients were carried out. RESULTS: From April 13 through May 8, 2003, there were 175 SARS cases including imported ones, were identified with an incidence rate of 1.9 cases per 100,000. Among them, 14 died with a fatality of 8.0%. The whole process of epidemic in Tianjin was less than one month with the following features: (1) 93.7% of the total SARS cases in Tianjin were directly or indirectly transmitted by a super-spreader. (2) 68.6% of the total SARS patients were concentrated in 3 hospitals A, B and C which was menifastated in 'clustering'. Through study on the rest of the SARS patients, results showed that 16.8% of them were transmitted through family close contact and 2.3% due to contact to colleagues. However, 12.6% of the patients were not able to show evidence that they had any contact to a diagnosed SARS patient. At the early stage of the epidemic, a number of medical practitioners were infected, taking up 38.2% of the total SARS cases. Among the total number of 1 975 medical workers who participated in the SARS medical cares and treatments, 3.4% of them got infected. During the outbreak, all index cases and chains of transmission seemed to be clear, with only 3 patients not able to be traced for the source of infection, taking up 2% of the total SARS patients in Tianjin. Among the 10 index cases, only the super spreader and another one index case transmitted the virus to their contacts but the rest of index cases did not cause any secondary infection. CONCLUSION: Though SARS is clinically severe and can be spreaded quickly, the epidemic can be under control within a short period of time if chains of SARS transmission are broken down and effective measures as isolation and quarantine against patients as well as underscoring awareness among the publics in a scientific way, being carried out.

Infectious diseases and the dental office.

Dentists and other health care workers have long been concerned about a variety of infectious agents that may be transmitted within the dental setting. In recent years there has also been widespread concern among the general public. Many infectious diseases, including HIV, hepatitis, tuberculosis and syphilis, are important both because of their potential transmissibility and because the first manifestations of the disease may appear in the oral cavity. A knowledge of these diseases will allow the practitioner to recognize associated lesions and also to take appropriate steps to minimize the risk of transmission in the dental office.

The use of povidone-iodine in superficial partial-thickness burns.

Infection is of primary concern to those practitioners treating burns patients, as it is one of the primary complications associated with acute wounds and particularly with superficial partial-thickness burns. In the fight to reduce the risks, many practitioners deploy common antimicrobials agents prophylactically to help reduce risks, e.g. povidone-iodine. This review will examine the evidence to support this practice. The deployment of povidone-iodine in wound care is highly controversial, with questions being raised concerning not only the effectiveness of the product but also its safety and effect on wound healing. The use of povidone-iodine has been investigated both in vitro and in vivo, resulting in conflicting and often contradictory results. Of the work completed to date, researchers have failed to identify or control for extraneous variables which makes it difficult to compare and interpret research findings. The potential benefits or harm that the use of povidone-iodine may elicit in acute wounds is yet to be established.

Occupational respiratory disease in mining.

This review is based on research-based literature on occupational lung disease in the mining and related industries, focusing on conditions of public health importance arising from asbestos, coal and silica exposure. Both 'traditional' and 'new' concerns about occupational respiratory disease in miners are addressed, with the inclusion of practical evidence-based findings relevant to practitioners working in developed and developing countries. Mining is not a homogeneous industry since current miners work in formal and informal operations with numerous, and often multiple, air-borne exposures. A further occupational health challenge facing primary care practitioners are ex-miners presenting with disease only after long latency. The sequelae of silica exposure remain an occupational health priority, particularly for practitioners who serve populations with concomitant HIV and tuberculosis infection and even when exposure is apparently below the statutory occupational exposure level. Coal workers' pneumoconiosis, asbestos related diseases, lung cancer and other occupational respiratory diseases remain of considerable importance even after mining operations cease. While mining exposures contribute significantly to lung disease, smoking is a major factor in the development of lung cancer and chronic obstructive airways disease necessitating a comprehensive approach for prevention and control of mining-related occupational lung disease.

The application of near patient testing to microbiology.

Near patient testing (NPT) was the norm in days when urine was examined by smell and taste. More recently, general practitioners and physicians in genitourinary medicine began to use light microscopes in their consulting rooms to examine urine for pus cells and urethral and other swabs for pathogens. Increasing knowledge has led to specialisation, however, with clinicians obtaining specimens for examination by others. Improved technology has speeded up the practice of medicine, raising expectations of patients and doctors alike, and reductions in the size and expense of testing instruments have made a renaissance of NPT possible. Such a rebirth has already been seen in high dependency units and neonatal intensive care units, where arterial blood gases and serum bilirubin have to be tested in less time than it would take a sprinter to reach the laboratory. People with diabetes, rushing about in the community, stop and test their own blood glucose to determine the ideal dose of insulin, and patients with asthma measure peak expiratory flow rates to titrate doses of inhaled and oral corticosteroids. To what extent has NPT developed in microbiology? General practitioners have nitrite dipsticks and dipslides with which to identify urinary tract infections and elsewhere in this issue the prospect for testing for Helicobacter pylori infection is discussed. Do-it-yourself HIV testing kits can be bought in some countries. Are these desirable developments for communicable diseases, the results of whose investigation are used not only to benefit the individuals tested but also to monitor trends in populations and determine policies for the prevention and control of infection? If NPT is desirable, or inevitable, in microbiology, how can it be developed so as to ensure a high quality service both for patients and the population? This review considers the implications of NPT in the field of communicable diseases for microbiology laboratories, quality assurance, accreditation, and the legal framework in which medical devices are used.

Vulvovaginitis: promotion of condom use to prevent sexually transmitted disease.

Many studies have suggested that merely warning people about the dangers of sexually transmitted diseases (STDs) and urging the use of condoms as protection will not result in widespread use of condoms. Regular condom use appears to be grounded in knowledge of its effectiveness, perception of STD risk, and belief in a partner's acceptance. But these are not the only barriers to condom use. Negotiating condom use often comes at a sensitive stage in intimate relationships, when individuals prefer to avoid such discussions and simply to trust the powerful and compelling feelings of mutual attraction. This review will consider (1) the effectiveness of condoms in preventing STD transmission, (2) barriers to the use of condoms, and (3) recommended strategies to promote acceptance and use of condoms by heterosexual women.

Health risks of travelers in South Africa.

Large numbers of tourists visit South Africa every year. Travelers to urban areas are at little risk of contracting an infectious disease, however the adventure traveler is at increased risk. Yellow fever is not known to occur in South Africa. Malaria is endemic in Mpumalanga and KwaZula-Natal. Schistosomiasis is endemic in large parts of the country. Although rabies is found throughout the country, only a small number of human cases is reported. High risk areas are KwaZulu-Natal, the eastern Cape and Mpumalanga provinces. The incidence of human immunodeficiency virus (HIV) infection is high and counseling regarding sexually transmitted diseases is important. Sanitation of water is excellent in most large cities and towns; however travelers to rural areas should exercise caution. Arbovirus infections do occur but relatively few cases are reported. The hiker is at risk for tick bite fever and should be counseled. Since the abolition of apartheid, South Africa has been seen as an inexpensive, high quality destination by many tourists. In 1997, a total of 5,436,848 travelers from many different countries visited the country. Areas most frequently visited include Johannesburg, Cape Town, Durban, the Garden Route, Kruger National Park, KwaZulu-Natal and Pretoria. The most common reason for visiting the country was holiday (44%), followed by visiting friends and relatives (23%), business travel (27%) other (6%).1 Travelers, to the larger cities such as Johannesburg, Cape Town and Durban are at little risk of acquiring an infectious disease. The adventure traveler however is at greater risk as parts of the country are endemic for malaria, schistosomiasis, rabies, food and waterborne diseases, sexually transmitted diseases and arbovirus infections. Accidental deaths due to motor vehicle accidents and interpersonal violence are important health risks in South Africa. Travelers visiting popular attractions are at significantly lower risk. However this has never been quantified. This review aims to address the occurrence of infectious diseases and attempts to give guidelines to practitioners caring for travelers.

Feline immunodeficiency virus diagnosis after vaccination.

Prior to the widespread use of vaccination for the control of feline immunodeficiency virus (FIV) infection, diagnosis was made by the detection of antibodies against FIV. A number of commercial animal side tests perform quite well for this determination, with positive predictive values between 91 and 100% and negative predictive values between 96 and 100%. Furthermore, results of these tests could be confirmed by western blot analysis of FIV test-positive sera. Currently, a killed whole virus FIV vaccine has been made available to practitioners. Vaccinated cats seroconvert by ELISA and western blot, making presently available diagnostic tests, which rely on antibody detection, useless in cats after vaccination. The advisory panels of the American Association of Feline Practitioners and Academy of Feline Medicine both recommend testing for feline leukemia virus antigen and FIV antibody before vaccination.

A randomized control trial of an opportunistic health screening tool in primary care for people with intellectual disability.

People with intellectual disability have an increased variety of health care problems compared with the general population. The transition of care for such people from institutions into the community places them in a primary care system already facing increasing demands for their services. There is a consensus that health screening is at its most useful in identifying functional disabilities. Therefore, an intervention which helps the general practitioner (GP) towards opportunistically checking those areas of health most often deficient in people with intellectual disability would appear of considerable benefit (especially if information directing the GP towards appropriate secondary care services is also provided). The present study was designed to evaluate the impact of such an intervention.

Morbidity and healthcare utilisation of children in households with one adult: comparative observational study.

OBJECTIVE: To identify and consider differences in morbidity in children in households with one adult presenting to general practitioners compared with children in households with more than one adult. DESIGN: Observational study; data analysed with logistic regression controlling for age, sex, and practice. SUBJECTS: 93 356 children aged 0-15 years included in the fourth national study of morbidity in general practice and for whom data about household structure were available. Among them 10 983 (11.8%) were living in households with a sole adult. METHODS: Morbidity data were recorded from each consultation as the assessment diagnosis made by the general practitioner. MAIN OUTCOME MEASURES: Number of consultations and consultations per person for any illness, infections, acute respiratory infections, asthma, and accidents; number presenting and mean consultations per person for immunisation; number receiving home visits and home visits per person visited; average annual frequency of consultation among those consulting. RESULTS: Compared with children in other households, a higher proportion of children in households with one adult consulted for infections and accidents. The proportion consulting for immunisation was lower and the proportion receiving home visits greater. Mean numbers of consultations per person consulting were also generally higher for all conditions. For infections, accidents, and home visits, the differences were evident in all age groups. CONCLUSIONS: The study confirms the importance of single parent families as an indicator of deprivation. Children in such families should be targeted for immunisation and accident prevention.
