Dynamic axial external fixation in the surgical treatment of tibia vara

Osteotomy is the well-established treatment of Blount's disease (tibia vara), although the types of fixation used vary considerably. The use of dynamic axial external fixation to stabilize osteotomies for tibia vara until solid union occurs without the use of supplemental casting has not been reported by other authors. From 1985 until the present, we have used osteotomy with dynamic axial external fixation as treatment of 31 tibiae in 23 patients. All osteotomies healed and there was no postoperative loss of correction. There was an average correction of 20 degrees between the pre- and postoperative mechanical axis. Advantages of dynamic axial external fixation include ease of application, adjustability, early weight bearing, the ability to lengthen the extremity, and no second operation for removal of hardware. Based on our results, we believe that dynamic axial external fixation is an excellent form of osteotomy stabilization in the surgical treatment of tibia vara.     

Mass exchange between droplets during head-on collisions of multisize sprays

A derivation of sectional equations for mass exchange between colliding droplets during head-on collisions of multisize (polydisperse) sprays is presented. The collision terms of these equations account for binary collisions which lead to coalescence and immediate break-up into two new droplets which differ in mass from the original droplets. That is, mass is exchanged between the original droplets. The amount of exchanged mass is allowed to vary between 0 and 100% of the mass of the donor droplet. The new equations are employed here to analyze the time evolution in droplet size distributions of two head-on colliding polydisperse sprays.     

Minor histocompatibility antigens as targets for T-cell therapy after bone marrow transplantation

BACKGROUND: Topical antimicrobials have been considered for treatment of secondarily infected wounds because of the potential for reduced risk of adverse effects and greater patient convenience. We compared mupirocin cream with oral cephalexin in the treatment of wounds such as small lacerations, abrasions, or sutured wounds. METHODS: In 2 identical randomized double-blind studies, 706 patients with secondarily infected wounds (small lacerations, abrasions, or sutured wounds) received either mupirocin cream topically 3 times daily or cephalexin orally 4 times daily for 10 days. RESULTS: Clinical success at follow-up was equivalent in the two groups: 95.1% and 95.3% in the mupirocin cream and the cephalexin groups, respectively (95% confidence interval [CI], -4.0% to 3.6%; P = .89). The intention-to-treat success rate was 83% in both groups. Bacteriologic success at follow-up was also comparable: 96.9% in the mupirocin cream and 98.9% in the cephalexin groups (95% CI, -6.0% to 2.0%; P = .22). The occurrence of adverse experiences related to study treatment was similar for the 2 groups, with fewer patients in the mupirocin cream group reporting diarrhea (1.1% vs 2.3% for cephalexin). CONCLUSIONS: Mupirocin cream applied topically 3 times daily is as effective as oral cephalexin given 4 times daily for the treatment of secondarily infected wounds and was well tolerated.     

Pathways to change in the psychotherapy of depression: Relating process to session change and outcome.

Identified a pathway from in-session process, and problem resolution, to post-session change and final outcome. Two brief treatments for depression, one using client-centered (CC) and the other process-experiential (PE) interventions, were compared on client process and outcome. The PE group showed significantly higher levels of experiencing, vocal quality and expressive stance, and greater problem resolution than the CC group in 2 of 3 PE interventions studied. Ss' degree of problem resolution correlated significantly with depth of experiencing, and sustained resolution over treatment resulted in better outcome. Ss' task-specific post-session change scores correlated significantly with change in depression post-therapy and 6 mo later, indicating that repeated post-session change is related to reduction in symptomatology.

Memory, emotion, and REM sleep.

Explored the manner in which REM sleep deprivation might affect various aspects of memory processing. A series of tests, including S. Sternberg's (see record 1966-10810-001) test of scanning of immediate memory, past personal and nonpersonal memory, and past emotional memories, was administered to 8 college students after baseline, control-awakening, and REM-deprivation nights. Results show that only past, emotionally important memories may have been affected by REM deprivation; access to the emotion connected with the memories was decreased. This finding is discussed in relation to a possible function of REM sleep and to the effects of REM deprivation on depression.

Influence of some hypnotist and subject variables on hypnotic susceptibility.

Randomly assigned 48 21-56 yr. Old females to 1 of 4 groups given different information with regard to a hypnotist's warmth and experience. The 6 male graduate student hypnotists had previously been judged on their objective warmth and competent appearance. Following structuring, all ss underwent individual hypnotic induction. As predicted, ss run by the objectively warmer, more competent appearing es obtained significantly higher susceptibility scores. Structured warmth produced significant differences only in ss run by the objectively less warm es. Both structured warmth and experience affected ss' subjective impressions of whether they thought they had been hypnotized. The complex relationship between antecedent variables and the various objective and subjective dependent indicators of hypnotic phenomena are discussed.

Defensive sesquiterpenoids from a dipterocarp (Dipterocarpus kerrii)

Four sesquiterpenoids (2, 4, 7, and9) have been isolated and characterized from the termiticidal fraction ofDipterocarpus kerrii resin. The major constituent of this resin is -gurjunene (1).Presented at the Third Annual Meeting of the International Society of Chemical Ecology, June 21–24, 1986, University of California, Berkeley.
