Abstract
A monoclonal antibody-based dot-ELISA was developed for the detection of antigen in the sera of cattle with Taenia saginata cysticercosis. After pretreatment of the sera with trichloroacetic acid, antigen could be detected in experimentally infected animals from five weeks after infection. The assay distinguished animals harbouring living cysts from those carrying only dead cysts. A reliable diagnosis of animals harbouring less than 100 cysticerci was not possible, but in cattle with more than 100 living cysticerci the sensitivity was 87.5 per cent; the specificity of the test was 93.5 per cent. These values were very similar to those obtained with a sandwich ELISA.

Abstract
The Prince of Wales, Prince Henry, and Prince of Wales Children's Hospital offered an Extended Critical Care Orientation Program for the first time in 1990. This program included pre-course worksheets, a five day lecture series and an Individual Clinical Learning Contract. This paper will consider the impact that the program has had on the critical care units involved. Ongoing evaluation questionnaires indicated that the program was successful. The program met with continued support and enthusiasm from nurse administrators, nursing unit managers, clinical educators, ward staff and course participants. Early figures have indicated that at twelve months post program, the overall retention rate was 71%, compared to 41.1% in the twelve months prior to program commencement.

Abstract
Chronic suppurative otitis media affected 3.8% of 3500 Solomon Island children under 15 years (and 6.1% under 5 years) and was the sole cause of conductive hearing loss recorded in 265 children tested audiometrically. It was characterised by early onset (65% under 18 months) male preponderance and large central tubotympanic perforations. Measles, respiratory infections, swimming and malnutrition were identified as aetiological factors amenable to intervention. Proteus and pseudomonas were the principle aerobes isolated from ear pus and gentamicin the only antibiotic tested to be effective against them. However although a prospective therapeutic trial demonstrated a significantly improved outcome after aural toilet, no additional benefit was imparted by concurrent ototopical boric acid or aminoglycoside solution or oral antianaerobic clindamycin. Parental tuition in aural cleaning, avoidance of ear water entry, nose blowing and breathing will yield a good result in up to 60% of children in half of whom tympanic healing occurred.

Abstract
Auckland general practitioners were surveyed to assess their use of computers. Forty-eight practitioners (9.6%) had computers which were primarily used for practice administration. The main benefit offered by the computer was an improvement in quality of work rather than a reduction in quantity. Areas of dissatisfaction revealed by the survey included cost, limited flexibility, and the consequences of computer failure. Although most respondents suggested improvements in specific areas, many felt that the age of computerised general practice had arrived.

Abstract
Injection of aminoglycosides into a filter chamber was compared with retrograde injection into i.v. tubing for delivery of intermittent drug dosages at low infusion rates in neonates. In 50 infants receiving gentamicin sulfate and 21 receiving amikacin sulfate for at least two days by retrograde i.v. infusion, peak and trough concentrations of the drugs were obtained. A subsequent dose was administered using the filter device, and peak and trough concentrations were obtained. For each infant, the difference between trough and peak concentration (delta C) was compared for the two methods. In vitro testing for gentamicin concentration was performed using the same infusion systems (10 trials for each system). For both in vivo and in vitro testing, the infusion flow rate was 10 mL/hr. For infants receiving gentamicin, delta C was greater for the filter device in 32, greater for retrograde infusion in 13, and equal in 5. The mean gentamicin delta C was significantly greater for the filter chamber method than for retrograde infusion. The in vitro studies showed significantly better gentamicin recovery with the filter device than with retrograde infusion. For amikacin, delta C was greater for the filter device in 15 infants, but the mean amikacin delta C was not significantly different for the two methods. At low flow rates commonly used in infants, the infusion system using the filter device was equal to or superior to retrograde infusion for ensuring complete delivery of intermittent drug doses.

Abstract
The nephrotoxicity of gentamicin and amikacin was compared during presumed sepsis in 107 premature neonates. To examine the possibility that nephrotoxicity was directly associated with the clinical conditions of "sepsis," a control group of 26 chloramphenicol-treated newborns was also studied. Two markers of proximal renal tubular injury, N-acetyl-beta-glucosaminidase (NAG) and beta 2-microglobulin, were measured in 6-hr aliquots of urine. Because urine creatinine excretion increased with postconception age, markers were expressed in terms of excretion rate rather than per milligram of creatinine. The NAG excretion rate was significantly higher in gentamicin-treated patients (138 +/- 10 U/min, mean +/- SE) than in amikacin-treated patients (85 +/- 7 U/min) but did not differ between patients treated with amikacin and those treated with chloramphenicol (81 +/- 11 U/min). Excretion of beta 2-microglobulin did not differ among the three patient groups. We conclude that amikacin may be less nephrotoxic than gentamicin in the premature newborn.

Abstract
The purpose of this study was to examine the combined effects of oral contraceptive (OC) use and strenuous exercise on the lipid profiles of a group of 11 women runners. The five runners who used OCs had lipid profiles within normal ranges. When compared with a group of six runners who were not using OCs, matched for body fat and cholesterol intake, no significant differences in lipid profiles were seen. Women who choose to use OCs may offset previously documented alterations in lipid levels through a regular physical exercise program.

Abstract
To evaluate the ability of a loading dose of chloramphenicol succinate to rapidly, achieve adequate serum concentrations of chloramphenicol, we compared two intravenously administered dosages of chloramphenicol succinate given to initiate treatment. Thirteen premature neonates received an initial dose of 12.5 mg/kg; 26 received a loading dose of 20 mg/kg. Capillary blood samples were obtained at two, four, and 12 hours after the first dose. After the dose of 12.5 mg/kg, 45% of the neonates did not achieve serum concentrations greater than 10 mg/L. After the loading dose of 20 mg/kg, all neonates achieved concentrations greater than 10 mg/L. The peak chloramphenicol concentrations after the 12.5 mg/kg dose was 8.8 +/- 11.2 mg/L (+/- SEM) and after the 20 mg/kg loading dose, 15.9 +/- 0.7 mg/L. The disposition of chloramphenicol was age dependent. Chloramphenicol concentration peaked at four hours in neonates less than or equal to 2 days postnatal age and at two hours in neonates 3 to 55 days postnatal age. Chloramphenicol succinate concentrations were greater in younger than in older neonates at both two and four hours after the dose. We conclude that a loading dose is appropriate when using chloramphenicol succinate in neonates.

Abstract
The private health insurance industry in the United States began as a money-collection mechanism for hospitals and doctors, and has evolved into an important profit-making sector of the economy. Blue Cross is dominated by hospital representatives and serves to channel money into the nation's hospitals. Physicians control Blue Shield and are its principal beneficiaries. And commercial insurance companies are closely linked to banks and industrial corporations through the country's large financial empires. Some effects of this elite control over the health insurance industry have been inadequate and distorted insurance coverage, discrimination against the elderly, the sick, and the poor, and rapidly rising medical costs. In addition, the control of Medicare and Medicaid by private insurance institutions has contributed to the enormous inflation produced by these programs. Though governments, consumers, and even the insurance industry itself are beginning to apply controls to the unprecedented medical inflation of the late 1960s, these controls tend to limit access to health care, especially for low-income people. Unless insurance companies are barred from the health care field and a public financing mechanism based on progressive taxation is introduced, health care will never be an equal right for everyone in the United States.
