TestPack Strep A
Abbott Laboratories has expanded its family of diagnostic products for the physician's office with the first rapid confirmatory test for strep throat. This 7-minute test, known as TestPack strep A, enables doctors to provide fast, highly accurate results in their offices and requires no instrumentation or technical training.
TestPack strep A is expected to increase market growth because it overcomes a major objection health care professionals have to currently available rapid strep tests. A market study revealed that 30% of officeUltra Pampers
Research presented at St. Vincents Hospital and Medical Center by scientists from Procter & Gamble deciphers for the first time how diaper rash develops on infant skin. The research, which was conducted over a 5-year period, will be published in the medical literature, some of which appeared in the February 1986 issue of Pediatrie Dermatology. The research illustrates that a new Pampers disposable diaper product. Ultra Pampers, can interrupt the diaper rash process.
"We have discovered," said Dr. Deborah Anderson, of Procter & Gamble's professional and regulatory services group, "that in order for diaper rash to develop, the skin must first become damaged or compromised. Two factors cause the skin to become damaged: wetness and digestive protein in fecal matter. Once skin is compromised, it is more susceptible to infection and irritation, factors that cause diaper rash."
"The innovation pioneered by Ultra Pampers has created a product that helps maintain healthy baby skin, " said Richard Nicolosi, vice president and general manager of Procter & Gamble's paper products division. "Forthat reason, the National Association of Pediatrie Nurse Associates and Practitioners (NAPNAP) has accepted Ultra Pampers and awarded it the NAPNAP seal." The seal, which will appear on all Ultra Pampers boxes and in introductory advertising, reads, "Ultra Pampers has been proven effective in keeping skin dry and controlling pH - important for maintaining healthy baby skin." This is the first time the group has awarded its seal to any product.
AccuLevel Theophylline Test
A blood-monitoring test for theophylline levels that is quick, accurate, and requires no instrumentation is now available from Syntex Medical Diagnostics, a unit of Syntex Corporation. The AccuLevel™ Theophylline Test is the first and only whole blood, non-instrumented assay for theophylline drug levels. Potential users of the portable AccuLevel Tests include physician offices, hospitals, private laboratories and clinics.
This new technology was developed jointly with Syva Company, a unit of Syntex Diagnostics. The AccuLevel test kit consists of three primary components: a small plastic cassette that contains a Chromatographie paper strip uniformly coated with monoclonal antibodies to theophylline, an enzyme reagent containing a fixed amount of enzyme labeled theophylline, and a developing reagent.
AccuLevel is the first diagnostic test to employ whole blood. Other types of tests require serum, which must be separated from the patient's blood through centrifugation. To perform the AccuLevel test, the patient's blood sample, obtained from a simple fingerstick, is mixed with the enzyme reagent. The cassette is then placed in this solution. In just a few minutes, the mixture migrates up the Chromatographie strip by capillary action. As the solution migrates up the strip, a special window on the cassette changes color, indicating that capillary migration is proceeding normally. The enzyme- labeled theophylline and theophylline from the patient's blood sample bind to the monoclonal antibodies on the strip. The height of this binding corresponds to the concentration of theophylline in the patient's blood.
After 15 minutes, the cassette is transferred to the developing reagent. The theophylline-bound portion of the paper strip turns a distinct blue for an easily read result. A table is provided so that based health care professionals who had evaluated rapid strep tests rejected their use because results were difficult to read. TestPack strep A provides an objective, easy-to-read answer. A plus (+) sign appears on the test reaction disk to indicate a positive result and a minus [ - ) sign to indicate a negative result. Moreover, the system has two built-in controls to reduce procedural errors.
Abbott introduced the TestPack system in January 1986 with a simple, 3-minute early pregnancy test. Two months after the TestPack pregnancy test was introduced, Abbott assumed the leadership in the U.S. market for laboratory and physicians' office urine pregnancy testing. Several additional tesrs for TestPack are planned for the future.
Group A strep is a widespread bacteria and a common cause of sore throats. Conventional culture methods to confirm strep A may take up to 48 hours, which can delay diagnosis and treatment. Rapid diagnosis is desirable to limit the spread of the disease through the population and to prevent the severe complications that can result from strep A infections.

The primary goal of a clinician caring tor a neonate is to contro/ the oxygen and temperature levels to which the baby is exposed. This care takes on even greater importance if the infant is battling illness or post-birth complications.
To help physicians care for critical-status neonates, Utah Medical Products, Inc., is manufacturing the Disposa-Hood™, the first disposable oxygen hood for infants. Thermoformed from a sheet extruded from Kodar® PETG, a copolyester supplied by Eastman Chemical Products, Inc., the Disposa-Hood incorporates many improvements over conventional infant oxygen hoods, says Darla GiIf, Utah Medical's vice president of sales and marketing.
"Because our infant oxygen hood is disposable, there is no danger from cross contamination," Gill points out. "It is also more cost effective because there is no maintenance or turnaround time needed. Most importantly, the Disposa-Hood is designed to maintain the optimum levels of oxygen and temperature around the baby's head."
According to a study conducted by William R. Howard and Richard Kuschinsky of St. Margaret's Hospital for Women in Boston, the Disposa-Hood retains 98% of the administered Fio2 (enriched oxygen) with a 1/2" space left in the neck opening, in tests with a snugly-fitted obstruction in the neck opening, there is no Fi^sub O2^ loss. Even with no obstruction, 66% to 85% of the Fi^sub O2^ is retained.
Located at the back of the Disposa-Hood is a round diffuser connection which has been specifically designed to disperse the inlet gas along the inner surface of the hood rather than allowing it to blow directly on the infant's head. This arrangement provides more precise control of the FiO2 while minimizing convective heat loss.
Because of the exceptional clarity of Kodar PETG, physicians can observe an infant from any angle with no seams to get in the way. The copolyesters shatter resistance is ideal for oxygen hood applications. Its light weight makes the hood easy to transport and store. In addition, it is easily molded to form the hood to exact specifications.

The Lexlngton School for the Deaf Foundation
The Lexington Center Foundation/Lexington School for the Deaf has published "No-Go-Tell!," a child protective curriculum for very young disabled children. According to Dr. Elisabeth «rents, director of Lexingtons Child Abuse and Disabled Children Project, "the disabled child is a vulnerable, high-risk candidate for sexual exploitation and abuse. It is of vital importance that each disabled child develop the skills necessary to prevent victimization."
"No-Go-Tell!," designed specifically for disabled preschool and early elementary school-aged children, focuses on four major concepts:
1. Making the distinction among family, friends, everyday acquaintances and strangers.
2. Developing an awareness of the body and "private parts."
3. Recognizing good touch, bad touch, confusing touch, and inappropriate sexual touch.
4. Learning who to tell (the parent and the teacher) and how to tell about an abusive incident.
The new curriculum was prepared by physicians and psychologists experienced in work with disabled children. It features a set of anatomically correct boy and girl dolls for role-playing throughout the curriculum and for demonstrating inappropriate sexual touch; a system of fold-outs and flaps to make the abstract concepts of sexual exploitation and abuse easier to understand; a separate teachers' manual and parents' manual that offers instructions for curriculum implementation and guidelines for a parentsensitizing session; detailed curriculum adaptations to make the material relevant to the needs of blind, learning disabled, emotionally disturbed and educably retarded children; a post- instruction test to insure that each child has acquired the skills necessary to prevent victimization.
"No-Go-Tell!" Is available for $300 (plus $10 for shipping and handling) from The Lexlngton Center Foundation/Lexington School for the Deaf, 30th Avenue and 75th Street, Jackson Heights, N.Y. 11370. Telephone: (718) 899-0808.
