Excimer Laser no tratamento do vitiligo em 123 pacientes: estudo retrospectivo

Introduction: Vitiligo is cosmetically disfiguring and can cause significant psychological morbidity. Most therapies require protracted treatments and can lead to disappointing results. More recently, 308 nm Excimer laser has proven to be effective in treating vitiligo. Objective: To analyze the effectiveness and patient satisfaction of 308 nm Excimer treatment for vitiligo patches in a variety of locations on the body. Methods: Patients with generalized or localized vitiligo (n = 123, 321 lesions), were studied. The patients were treated at a private practice between 2007 and 2010. Two independent examiners analyzed the response to the therapy by comparing clinical and photographic records before and after treatment. Results: More than half (n = 77) of the patients presented repigmentation greater than 60%, 26 presented 40-59%, and 20% had levels less than 39%. Facial lesions responded better to treatment than those in other body parts. Elbows, hands and feet were the less sensitive areas. In general, the patients were satisfied with the treatment. Conclusion: The use of Excimer laser for treating vitiligo was effective and safe, producing satisfactory cosmetic results and improving patients' self esteem.

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.

Comparación de la conductancia hidráulica dentinaria, de acuerdo al tiempo de aplicación de desensibilizantes con base de oxalatos

ABSTRACT. Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application. Methods: 45 dentin discs measuring 1 mm thick were obtained from human third molars which were free of caries and in no occlusion; the samples were obtained from patients aged 16 to 30 years. Discs were sorted out into three study groups (n = 15) depending on the time of application of a commercial solution of oxalate-based dentin desensitizer (DD) (BisBlock®) which contains ˂ 5% oxalic acid of 1.5-1.8 pH: in group A the agent was applied for 15 s, in group B it was applied for 30 s, and in group C for 60 s. The hydraulic conductance of each disc was calculated after acid etching, which corresponds to the maximum permeability of discs (100%) after immediate application of oxalic acid, as well as seven and fourteen days of storage in saline solution. The statistical analysis was done with ANOVA test and post-hoc Games-Howell test. Results: 35,46 ± 23.41% in Group A, 36.34 ± 15.88% in Group B and 24.99 ± 14.99% in Group C, showing that the use of DD for 15, 30 or 60 s decreased permeability in a statistically significant manner (p <0.05). Conclusions: DD was effective in reducing hydraulic conductance regardless of application time, but this reduction was temporary only, since after seven days permeability returns to values close to those of baseline.

Esplenomegalia em cães: estudo retrospectivo

The aim of this study was to review the prevalence of canine splenic disorders by means of a retrospectiveanalysis of histological diagnosis after splenectomy. The results were confronted with laboratory findings, clinical signs and presence of cardiac arrhythmia and hemoperitoneum, in an attempt to establish the differentialdiagnosis of splenomegaly. One hundred and nine dogs assisted at the Veterinary Hospital of theSchool of Veterinary Medicine and Zootechny, University of São Paulo, were included in the retrospectivestudy, between 2002 and 2009. The average age was 10 years old ± 3, with no sexual predilection. Mixedbreed dogs was the most affected kind, and average weight was 22 kg ± 13. Overall, 52% (57/109) of dogswere splenectomized due to non-neoplastic diseases and 48% (52/109) to neoplastic diseases. Among thelatter, the most common diagnosis was hemangiosarcoma (28 dogs; 54%). Most frequent clinical signs includedanorexia, lethargy and vomiting. Results showed that dogs with low red blood cell count, low hematocritvalues and/or hemoperitoneum were more likely to have splenic malignant neoplasm. On the otherhand, sex, breed, size, age, cardiac arrhythmia and other laboratory parameters were not determining factorsin the differentiation of splenomegaly.

Avaliação laboratorial da cinomose canina: estudo retrospectivo de 25 casos no município de Araçatuba-SP

Canine Distemper is a contagious, severe and multisystemic disease caused by a virus from Morbillivírus genus. The virus is distributed worldwide and it presents a high lethality rate, affecting mainly dogs. The diagnosis is based on clinical signs associated with hematological fi ndings. The observation of Lentz bodies in erythrocytes and leukocytes is the defi nitive diagnosis for the disease. The aim of this work was to test the hypothesis that the hematological profi le in dogs positive for canine distemper differs according to blood cell type presenting Lentz bodies. For this purpose, 25 dogs positive for the disease were evaluated at the Veterinary Hospital “Luís Quintiliano de Oliveira” UNESP, Araçatuba city. The diagnosis was based on the observation of Lentz bodies in blood smears. Fromthe total, 64% of dogs presented anemia, 16% leucopenia and 12% leukocytosis. Lymphopenia occurred in 76% of dogs. Viral inclusions were observed solely in neutrophils (32%), lymphocytes (28%) and erythrocytes (12%). Concomitant observation occurred in lymphocytes and erythrocytes (4 %), in lymphocytes and neutrophils (12%), in neutrophils and monocytes (4%) and in neutrophils and erythrocytes (4%). In an isolated case Lentz bodies were observed simultaneously in neuthrophils, monocytes and lymphocytes. In conclusion, hematological profi le is not associated with the presence of viral inclusion in a particular cell type.
