Transformations of transference.

Transference can be understood to have complementary aspects: the experience in the here-and-now of the relationship with the analyst and the repetition of old relationships. The concept of an enactment is proposed to describe the vivid reexperience of childhood relationships in the here-and-now of the analytic relationship. Countertransference contributions to the enactment are discussed. Transference transformation results from the juxtaposition of the regressive transference enactment and transference experiences that are new and novel to the patient. The analyst can promote such changes by his interpretation of resistances both to the reexperience of the transference repetition and to awareness of the new and novel elements that spontaneously appear in the relationship with the analyst.

Down's syndrome: current screening techniques.

Antenatal screening for Down's syndrome traditionally relied upon performing amniocentesis for karyotype on pregnant women aged 35 years and older. This method detects approximately 20% of all Down's syndrome pregnancies, with a false-positive rate of 4.3%. By incorporating maternal serum alpha-fetoprotein values as an additional screening parameter to maternal age, 28% of all Down's syndrome pregnancies may be diagnosed, with a 35% reduction in false-positive results. Other screening parameters such as maternal serum unconjugated estriol and human chorionic gonadotropin may eventually make it possible to detect more than 65% of pregnancies with chromosomally abnormal fetuses, without compromise in false-positive rates.

Allergenic cross-reactivity between Callistemon citrinis and Melaleuca quinquenervia pollens.

Aqueous extracts of both Callistemon citrinis (bottlebrush) and Melaleuca quinquenervia (melaleuca) were analyzed for allergenic cross-reactivity. Inhibition analysis using the radioallergosorbent test (RAST) was performed on the ammonium bicarbonate extracts of bottlebrush (NH4B) and melaleuca (NH4M) pollens. RAST inhibition analysis demonstrated that the extracts contained allergenically cross-reactive components. Sephadex G-100 column chromatography of NH4B and NH4M extracts resulted in at least 4 distinct peaks for each extract analyzed. These fractions were designated NH4B1-NH4B4 and NH4M1-NH4M4. A modified dot-blot assay for detection of allergenic components was utilized to show that the first elution peaks of bottlebrush and melaleuca, NH4B1 and NH4M1, respectively, contained allergenic components. These allergenic components, NH4B1 and NH4M1, had estimated molecular weights of 50,000 and 35,000 daltons, respectively.

Isolation and characterization of cross-reactive allergenic components in Callistemon citrinis and Melaleuca quinquenervia pollen by trans-blot enzyme-linked crossed immunoelectrophoresis.

Antigenic extracts obtained from Callistemon citrinis (bottle brush) and Melaleuca quinquenervia (melaleuca) pollen were analyzed by crossed immunoelectrophoresis (CIE), tandem-crossed immunoelectrophoresis (TCIE), and trans-blot enzyme-linked crossed immunoelectrophoresis (TECIE). CIE analysis detected 14 and 12 antigenic components in bottle brush and melaleuca, respectively. TCIE analysis of bottle brush pollen, employing rabbit anti-melaleuca serum in the intermediate gel, demonstrated that all of the antigenic components detected were cross-reactive. Similar analysis of melaleuca using rabbit anti-bottle brush serum in the intermediate gel also showed that all of the antigenic components were cross-reactive. At least three bottle brush and two melaleuca cross-reactive pollen components were demonstrated to be allergenic by TECIE analysis of CIE and TCIE gels.

Diffuse rhabdomyomatosis of the heart.

The myocardium of a 13-year-old boy was infiltrated with cells like those of classical congenital rhabdomyoma. In contrast to the latter condition, in which distinct nodules are present, our patient had an infiltrated myocardium without a distinct tumor formation. The condition is similar to that reported earlier and may be designated as diffuse rhabdomyomatosis.
