Six patients with multisystem paracoccidioidomycosis proven by serology and culture or smear were treated with relatively brief courses of intravenous miconazole. Two had relapsed following prior therapy; 6 had active pulmonary, 4 laryngeal, 2 oropharyngeal, 2 lymphoid, and 1 abdominal disease. Paracoccidioides brasiliensis was highly susceptible to miconazole in vitro; minimal inhibitory concentration was less than or equal to 0.001 microgram/ml. Clinical examination showed a prompt and objective response in all patients, confirmed by smear or culture and X-rays; in 4/6 serological response was shown. Side effects were minor. Two patients relapsed 3--5 mo after therapy; another had a rise in antibody 6 mo after therapy and was given maintenance oral sulfa. One remains in remission 7 mo after treatment; two given oral sulfa after response to miconazole remain in remission 4--6 mo after treatment. Paracoccidioidomycosis responds well to miconazole, but longer courses may be needed to prevent relapse.

The use of multiple compasses to map and visualize magnetic fields is well-known. The magnetic field exerts a torque on the compasses aligning them along the lines of force. Some science museums show the field of a magnet using a table with many compasses in a closely packed arrangement. However, the very interesting interactions that occur between the compasses themselves are frequently neglected. In this paper we describe demonstrations, using arrays of compasses, that show these interactions and model magnetic domains in ferromagnetic materials.

The objective of this research was to determine the effect of grouping on the academic performance and creativity of 87 students from the Jalisco educational center for high abilities (CEPAC). Gains in academic performance and creativity due to grouping were hypothesized to be correlated with time spent at CEPAC. The Creative Imagination Test for Children (PIC-N) and for young people (PIC-J) were used, as well as the scores obtained in Spanish, mathematics and the general average at the entrance to the center at the end of the 2019 school year. The test was applied collectively to students when they joined the educational center, and after the end of the 2019 school year. In order to determine if there are improvements in academic scores after being included in CEPAC and to determine if there were changes in creativity, ANOVA split plot were carried out. To determine the relationship between school scores and creativity, Pearson correlations were performed. The results showed gains in academic performance and creativity when the permanence of students in the educational center is longer. It is concluded that grouping by ability produces gains in academic performance and in some components of creativity.

Background: Creativity is one of the most relevant aspects in students’ training. One of the purposes of the present work is to show the lack of differences between boys and girls in creativity; the other is the possibility of improving creativity among high-ability students who received specific training as part of their intra-curricular content in a total grouping program for gifted students. Method: The sample consisted of 42 students from first to third grade (13 females and 29 males) and 58 students from fourth to sixth grade (21 females and 37 males). Creativity was measured with the CREA test for younger students and with the PIC-N for older students. Training was carried out through an Integral Innovation and Creativity Program (PIIC). Results: The results showed no differences between genders, except in one of the graphic creativity scales (Details). There were improvements due to the training in all measures of narrative creativity and in the scale of elaboration of graphic creativity. Conclusions: The main conclusions are the importance of increasing creativity with specific programs and the need to improve interventions in graphic creativity.

High ability students have differential cognitive characteristics that require a specific educational response to develop their full potential. Cluster ability grouping is one of the available approaches to respond to their training. One of the main criticisms of this teaching method, also supported by the big-fish-little-pond effect (BFLPE), is that high ability students may show a decrease in their self-concept. The aim of this research is to present the evaluation carried out by parents of primary school high ability students on the effect of an educational cluster grouping program on their personal and social adjustment, comparing these variables before the beginning of the school year and at the end of it. Approximately 100 students’ parents of the Educational Centre for Highly Ability Pupils participated in the evaluation. The instrument used for the evaluation was the Socialization Battery (BAS-2) for parents. The results showed that parents observed some improvements, either due to an increase in the scales measuring positive socialization variables or a decrease in the scales measuring negative socialization variables. The most substantial improvements are found in the second and third grades. We conclude that the results do not support the big-fish-little-pond effect (BFLPE).
