Hydroxyurea in the sickle cell anemia: toxicity and effectiveness

Objective: to evaluate the use of hydroxyurea with regard to effectiveness and toxicity in people with sickle cell anemia. Method: this is a retrospective descriptive study, developed with 57 medical records of patients with sickle cell anemia, treated at the University Hospital Center of Campo Grande (Mato Grosso do Sul, Brazil), from 1993 to 2005. Inclusion criteria: electrophoresis of hemoglobin in medical record; regular use of drugs, for an average of 196 weeks; dosage; and hematological analyses before starting treatment. Exclusion criteria: living with other hemoglobinopathies. The variables evaluated were: neutrophils count; platelets; leukocytes; hemoglobin; time using hydroxyurea; drug response to the optimal dosage; and number and type of episodes of hospitalization. The research protocol was approved by the Ethics Committee of Universidade Federal de Mato Grosso do Sul, under the Protocol 645. Results: of the 57 medical records, 3 cases were evaluated. Comparing the hematological values, according to Portaria 872, enacted on 11/12/2002, it was found that: cases A, B, and C present an use of hydroxyurea (500 mg/day) for four years, with an average of 196 weeks. Case A, female, decreased painful episodes and frequency of hospitalization, keeping hematological values with no toxicity. In Case B, female, there was one hospitalization due to pain crises and important hemolysis. It stood out, in case C, male, neutropenia with hematological values < 2,000/mm3 . Conclusion: in the cases analyzed, we observed a drop in the number of hospitalizations with the decrease in painful crises from three to one a year, and there was no toxicity with regard to the dosage and time using hydroxyurea, in all three cases. For more comprehensive results, one suggests further study on this therapy with significant samples of this clientele.

Detecção da procedência de plantas psicoativas pelos isótopos estáveis do nitrogênio (15n) e oxigênio (18o)

This research examines the merits of hallucinogenic plants considered and/or psychoactive substances, such as Cannabis sativa and Ipomoea violacea, using the isotope rates of stable isotope of oxygen (18O) and nitrogen (15N), continuing projects already developed by the research group at the Center for Stable Isotope (CIE), which evaluated the isotopes carbon-13. This paper helps in creating a database that we intent to use in evaluation of each plant merit. Through the IRMS (Isotope-Ratio Mass Spectrometry) technique, it has shown that some of the 24 samples of marijuana (Cannabis sativa L.) evaluated were similar to those grown in the regions of Fairbanks and Tanacross Alaska, USA. In turn, the 50 samples of Ipomoea violacea, coming from Botucatu (SP) and Três Lagoas (MS), got their differences detected, in order to clearly identify the discrepancies between their growing regions. Thus, it was possible not only to track the geographical differences between marijuana samples collected from different regions, but also evaluate the isotopic variation of leaf, flower and seed of Ipomoea violacea. With this database, it was possible to determine the origin region of the drug and/or detect where the cultivation was carried out, aiding in the search of the traffic control agencies, such as the Federal Police in Brazil

Procedência da cocaína e maconha definida por isótopos estáveis

Objectives: the aim of this work was to define the range of possible values for each isotope of carbon-13 and nitrogen-15 for cocaine and marijuana seized in Botucatu-SP, with the intention of distinguishing the geographical origin of the drug. Materials and Methods: samples of marijuana and cocaine were collected at the time of incineration. Then, at the Stable Isotope Center from São Paulo State University in Botucatu, São Paulo, Brazil, samples of marijuana were subjected to the drying process and subsequent grinding. Samples of cocaine were not submitted to the processes of drying and grinding because they were already in adequate granulometry. Subsequently, the samples of both drugs were weighed in accordance with the standards for carbon-13 and nitrogen-15. Lastly, CO2 and N2 gases were obtained from the samples through the elemental analyzer. They were then analyzed in a mass spectrometer to obtain values of δ13C and δ15N in ‰. Results and Discussion: the results of marijuana allowed for comparison with regions of Queensland, Australia, according to the range of δ13C between -29.9 ‰ and -29.3 ‰ and δ15N range from 4.1 ‰ to 5.8 ‰. The results were also consistent with those of the state of Pará, Brazil, where the values of δ13C and δ15N were -30.3 ± 0.7 ‰ and 5.0 ± 1.3 ‰, respectively. Also the results were in accordance with those from the state of Mato Grosso do Sul, Brazil, in which δ13C values varied by -28.7 ± 1.3 ‰, and δ15N values varied by 6.6 ± 1.1 ‰, respectively. In both regions, the samples identified as being from Pará and Mato Grosso do Sul showed an overlap. In addition, the results fitted with data from the state of Maranhão, in which the values of δ13C and δ15 N were -28.8 ± 1.6 ‰ and 2.9 ± 2.5 ‰, respectively. In the case of cocaine, the present study could not be related to the results from the literature. One possible explanation may be related to the non-purification of ...

O sujeito-comprimido

Is it possible to encapsulate in a pill the benefits of an analytical treatment? Quickly suspending the symptoms? Since the nineteenth century psychiatry has offered to the so called mentally ill "medieval forms" of treatment, as is the case of institutional admissions, the straightjacket, lobotomies, shock treatments, etc. What has changed since the mid-twentieth century advent of chlorpromazine, the first psychoactive drug, and the "psychopharmacological revolution"? Today with the Psychiatric Reform mental institutions admissions are being gradually abandoned, yet we see the rise of psychoactive drugs as protagonists in mental health treatment. This theoretical essay is an extension of a master's thesis in progress on the long-term use of psychotropic drugs. It falls within the field of mental health, specifically in the debate on the medicalization of society in contemporary processes of subjectivation of the psychiatric clinics and the treatment modalities currently offered to individuals in their suffering-existence. Thus, we seek to problematize this degrading psychiatric clinics, which produces what we call the pill-subject.
