Reducing the incidence of tap-water scalds: strategies for physicians

Burns are a significant cause of severe injury and death. Scalds, including those from hot tap water, are one of the most common causes of burns, especially in vulnerable populations (children, elderly people and people with physical and cognitive disabilities). Although people generally recognize the danger associated with hot tap water, many are unaware of the short exposure periods that can result in serious burns. Tap-water scalds are preventable. Both active and passive prevention measures are beneficial in reducing this serious health hazard. Physicians are in a unique position to disseminate information on the danger of hot tap water and on ways to eliminate the risk to vulnerable populations. Not only do physicians have contact with these populations, they also have credibility as a source of health information for the public.     

Reviewing RAWP. Variations in admission rates: implications for equitable allocation of resources.

The review of the Resource Allocation Working Party (RAWP) formula by the National Health Service Management Board has considered the method used to account for cross boundary flows between health authorities. There is no consensus on how this should be done subregionally, as it raises the unresolved problem of the best method of estimating the size of catchment populations. Different methods produce different population sizes when the admission rates of individuals living in different districts vary. The National Health Service/Department of Health and Social Security acute services working group on performance indicators recently considered the assumptions made by different methods in terms of admission thresholds set by hospital clinicians. More complicated methods of assessing catchment areas seem to offer little advantage over the simplest method, but none of the methods answer the underlying questions of what truly determines admission rates and whether higher admission rates are better than lower ones. Empirical research into variations in admission rates and their relation to outcomes is important for determining the fair allocation of resources in future.     

Oral versus intravenous antibiotics for community acquired lower respiratory tract infection in a general hospital: open,randomised controlled trial.

OBJECTIVE--To see whether there is a difference in outcome between patients treated with oral and intravenous antibiotics for lower respiratory tract infection. DESIGN--Open controlled trial in patients admitted consecutively and randomised to treatment with either oral co-amoxiclav, intravenous followed by oral co-amoxiclav, or intravenous followed by oral cephalosporins. SETTING--Large general hospital in Dublin. PATIENTS--541 patients admitted for lower respiratory tract infection during one year. Patients represented 87% of admissions with the diagnosis and excluded those who were immunocompromised and patients with severe life threatening infection. MAIN OUTCOME MEASURES--Cure, partial cure, extended antibiotic treatment, change of antibiotic, death, and cost and duration of hospital stay. RESULTS--There were no significant differences between the groups in clinical outcome or mortality (6%). However, patients randomised to oral co-amoxiclav had a significantly shorter hospital stay than the two groups given intravenous antibiotic (median 6 v 7 and 9 days respectively). In addition, oral antibiotics were cheaper, easier to administer, and if used routinely in the 800 or so patients admitted annually would lead to savings of around 176,000 pounds a year. CONCLUSIONS--Oral antibiotics in community acquired lower respiratory tract infection are at least as efficacious as intraveous therapy. Their use reduces labour and equipment costs and may lead to earlier discharge from hospital.     

Deep venous thrombosis and pulmonary embolus after face lift: a study of incidence and prophylaxis

Deep venous thrombosis and pulmonary embolus are known risks of surgery. However, the incidence of these conditions in face lift is unknown. In this study, the incidence of deep venous thrombosis/pulmonary embolus after face lift is studied and factors associated with thromboembolic complications are evaluated. One-third of the active members of the American Society for Aesthetic Plastic Surgery were randomly selected. Participating surgeons completed a one-page survey providing information on face-lift procedures during a 12-month study period. A response rate of 80 percent was achieved, with 273 of the 342 surgeons responding to the survey. A total of 9937 face-lift procedures were reported in the 1-year study period. There were 35 patients with deep venous thrombosis (0.35 percent), 14 patients with pulmonary embolus (0.14 percent), and 1 patient death in the series. Although 43.5 percent of patients underwent face lift under general anesthesia, 83.7 percent of deep venous thrombosis/pulmonary embolus events occurred with general anesthesia. For prophylaxis for deep venous thrombosis/pulmonary embolus, 19.7 percent of the surgeons used intermittent compression devices, 19.6 percent used thromboembolic disease hose or Ace wraps, and 60.7 percent used no prophylaxis. Of patients developing deep venous thrombosis/pulmonary embolus, 4.1 percent were treated prophylactically with intermittent compression devices, 36.7 percent with thromboembolic disease hose/Ace wraps, and 59.2 percent with no prophylaxis. It was found that deep venous thrombosis/pulmonary embolus after face lift is a measurable complication experienced by one of nine surgeons surveyed. Deep venous thrombosis/pulmonary embolus is more likely to occur when the procedure is performed under general anesthesia. The majority of plastic surgeons surveyed used no prophylaxis for deep venous thrombosis when performing face-lift procedures. Intermittent compression devices were associated with significantly fewer thromboembolic complications, whereas Ace wrap/thromboembolic disease hose afforded no protection against deep venous thrombosis/pulmonary embolus when used alone. In conclusion, aesthetic surgeons should consider adopting intermittent compression devices when performing face lift under general anesthesia.     

Reducing the incidence of short estrous cycles in beef cows with norgestomet

Twenty-nine anestrous cows suckling calves 27 to 67 days old were allotted to 3 treatment groups according to calving date. Calves were weaned from all cows; 9 cows received no further treatment, while 10 were implanted with 6 mg of norgestomet 9 days before calves were weaned and 10 were implanted when calves were weaned. All implants were removed after 9 days. Twenty-two cows exhibited estrus within 10 days after treatment, and all exhibited estrus within 25 days. In the cows exhibiting estrus in 10 days, norgestomet reduced the incidence of 8 to 12-day cycles from 83.3 percent in the control group to 30 percent when implanted before weaning and to zero when implanted at weaning. Conception rates at first service were increased from zero for cows which were not implanted to 33.3 and 80 percent for those implanted before and at weaning, respectively. These data demonstrate that the presence of a progestogen before the first postpartum estrus increases conception rates and reduces the percentage of previously anestrous cows exhibiting short estrous cycles after their calves are weaned.     

Absenteeism among hospital staff during an influenza epidemic: implications for immunoprophylaxis.

The 1980-81 epidemic of influenza A/Bangkok 79 was responsible for increased absenteeism (1.7 times the rate for the corresponding period of the subsequent nonepidemic year) among selected hospital staff in Winnipeg''s Health Sciences Centre. Retrospective study of employment records for 25 of the centre''s largest departments showed excess sick-leave costs of about $24 500 during the 2-week period of peak absenteeism that included the epidemic. Although the centre was sampling prospectively for the virus the first positive results became available too late for chemoprophylactic measures to have been effective. The greater increase in absenteeism among nursing staff caring for patients with chronic respiratory disease and nurses working on general medical or pediatric acute infection/isolation wards suggested that these groups be targeted for influenza vaccination in hospitals.     

Prevalence of high-risk human papillomavirus type 16/18 infection among women with normal cytology: risk factor analysis and implications for screening and prophylaxis

Objective: To determine the prevalence of high‐risk human papillomavirus (HR‐HPV) 16/18 infection of uterine cervix among women in the reproductive age group, with cytologically normal cervical (Pap) smears; to analyse the risk factors for HR‐HPV acquisition and to address their implications for cervical cancer screening and prophylaxis in a low resource setting. Methods: Cervical samples from 769 cytologically negative women (age 18–45 years) attending a tertiary care centre in Delhi were subjected to HPV DNA testing and HR‐HPV 16/18 and low‐risk (LR)‐HPV 6/11 sub‐typing by polymerase chain reaction. Univariate risk factor analysis was carried out in HR‐HPV positive (n = 86) versus HR‐HPV negative women (n = 683) by chi‐square test. Results: The overall HPV prevalence among cytologically normal women was 16.6%. HR‐HPV16 was detected in 10.1%, whereas HPV18 was detected in 1% of women. HR‐HPV 16/18 comprised 67% of the total HPV positives. There was no decline in HR‐HPV positivity with age, and women aged 40–44 years were at significantly increased risk for HR‐HPV prevalence (P = 0.03). Statistically significant associations of HR‐HPV infection were found with risk factors such as high parity (P = 0.04), cervicitis/hypertrophic cervix (P = 0.01), unhealthy cervix (P = 0.04), rural residence (P = 0.03), low socioeconomic status (P = 0.01) and illiteracy (P = 0.07). Conclusions: Although the sample size was small, based on the observation that HR‐HPV 16 and 18 contributed significantly to the overall HPV prevalence in our setting, we speculate that testing/prophylaxis for these prevalent high‐risk types could perhaps make cervical cancer screening and preventive programmes cost‐effective. Larger community‐based studies on HPV prevalence and persistence are required to validate these findings before definitive recommendations can be made to the policy makers.
