Tratamento eclético da lepra: 20 anos de experiência

The author gives the clinical records of 20 patients, 14 of which were treated during 17 months, and the rest much less. The method used for treatment was the ecclectical — preferred by the A. since many years —, in which he associates electricity with minor surgery, chaulmestrol (pure or with 0.5 p. c. iodine or 4 p. c. creosote) and other auxilliary curative agents. The chaulmoogra derivatives were used daily as nostrils tamponage (2 p.c. mentholated or thymolated ester), periodically by injections inside the enlarged lymph nodes and nerve abscesses, and twice weekly by subcutaneous infiltrations (MUIR method) 5 c.c. each, and chaulmoogra soap tablets per os. The galvanocauterisation session was once per week, on active leprotic lesions, followed by painting with 30 p. c. trichloracetic acid solution. All 20 patients were bacilliferous before treatment, and became stronger positive after some months treatment. At the end 14 negativated and 6 remained positive and sometimes bacilli being very scanty. 16 out of 20 gave interesting serological reactions, viz.: Wassermann, Stern, Kahn. Rubino, Witebsky and Gaté (Formol-gel) positive in 5; Stern, Rubino. Witebsky and Gaté positive and Wassermann and Kahn negative in 2; Stern. Kahn, Witebsky and Gaté positive and Wassermann anticomplementary in 1; Wassermann. Stern, Kahn, Rubino and Gaté negative in 1. in the beginning, and a few months later Stern. Witebsky and Gaté becoming positive; Stern. Rubino. Witebsky and Gaté positive and anticomplementary W. in 1; Stern, Witebsky and Gaté positive and Wassermann. Kahn and Rubino negative in 1; Witebsky and Gaté positive and Wassermann, Stern, Kahn and Rubino negative in 1; Witebsky 3 times anticomplemantary and strongly positive Gaté in 1; Wassermann and Gaté positive in 1; Stern and Rubino positive in 1 and Stern test negative in one. In 7 cases high Formol-gel were associated with a high sedimentation index. Many cases had very high S.I. being a false measure of the severity of the disease; others remained very high notwithstanding the great improvement of the disease. All patients with more than 12 months treatment became practically symptom free. Lepra reaction amongst them was rare and always started by embolic rash, being controlled by destruction of such skin lesions by galvanocauterisation. In a few cases the lepromata infiltrated with "Subintrol" (a 3 p. c. special chaulmoogra soap prepared by Dr. ASTROGILDO MACHADO) were completely destroyd and never relapsed. In October 1946 Dr. ERNEST MUIR saw here a few cases treated by the author's method and suggested the combination of Diasone with galvanocauterisation which is being done now with satifactory results. The second part of this paper, reporting many leprosy cases treated by the so-called ecclectical method, which are symptom free and negativated since five to ten years, will be published as soon as the sulfone-therapy be summarised in some reliable scientific report to be compared with.

ParallelKnoppix - Rapid deployment of a linux cluster for MPI parallel processing using non-dedicated computers

This note describes ParallelKnoppix, a bootable CD that allows creation of a Linux cluster in very little time. An experienced user can create a cluster ready to execute MPI programs in less than 10 minutes. The computers used may be heterogeneous machines, of the IA-32 architecture. When the cluster is shut down, all machines except one are in their original state, and the last can be returned to its original state by deleting a directory. The system thus provides a means of using non-dedicated computers to create a cluster. An example session is documented.

How tight should one's hands be tied? Fear of floating and credibility of exchange rate regimes

This paper analyzes the linkages between the credibility of a target zone regime, the volatility of the exchange rate, and the width of the band where the exchange rate is allowed to fluctuate. These three concepts should be related since the band width induces a trade-off between credibility and volatility. Narrower bands should give less scope for the exchange rate to fluctuate but may make agents perceive a larger probability of realignment which by itself should increase the volatility of the exchange rate. We build a model where this trade-off is made explicit. The model is used to understand the reduction in volatility experienced by most EMS countries after their target zones were widened on August 1993. As a natural extension, the model also rationalizes the existence of non-official, implicit target zones (or fear of floating), suggested by some authors.
