This work aimed to characterize mortality by sickle cell disease in Brazil. The MEDLINE electronic database was searched using the terms ‘mortality’ and ‘sickle cell disease’ and ‘Brazil’ for articles published in the last five years aiming to provide a current analysis of the subject in question. Eight studies on mortality by sickle cell disease were carried out in the Brazilian states of Maranhão, Bahia, Minas Gerais, Rio de Janeiro and Mato Grosso do Sul. The majority of the deaths occurred in patients with sickle cell anemia, which is the most common genotype and causes the most severe clinical manifestation of the disease. In summary, there are few published studies on mortality related to sickle cell disease in Brazil, and most are from the state of Minas Gerais. This study emphasizes the importance of developing more studies on sickle cell disease mortality, so that it may be possible to profile gene carriers and give health professionals more data to strategize the delivery of more effective assistance to these individuals. Despite the early diagnosis of sickle cell disease by the Neonatal Screening Program and the use of preventive and therapeutic measures (penicillin, immunization and hydroxyurea), mortality by sickle cell disease on the world stage is still significant.

Objective: This study aimed to assess the knowledge of puerperal mothers about the Guthrie test. Methods: A total of 75 mothers who sought primary care between October 2014 and February 2015 were investigated. The form was applied by the main researcher and the data was analyzed, using descriptive statistics with Microsoft Office Excel, and Statistical Package for Social Sciences (SPSS) programs. Association tests and statistical power were applied.Results: Among the 75 mothers, 47 (62.7%) would have liked to receive more information about the newborn screening, especially regarding the correct sample collection period, followed by the screened morbidities. Most participants (n=55; 85.9%) took their children to be tested between the third and the seventh day of birth, as recommended by the Brazilian Health Ministry. Fifty-four women (72%) were unable to name the morbidities screened by the test in Minas Gerais, and they were also unaware that most have genetic etiology. The health professional who informed the mother about the Guthrie test was mainly the physician. This information was given prenatally to 57% of the cases, and to 43 % at the time of discharge from the hospital. The association test showed that mothers with higher education have more knowledge about the purpose and importance of the Guthrie test. The statistical power was 83.5%.Conclusions: Maternal knowledge about the Guthrie test is superficial and may reflect the health team’s usual practice.

Priapism is a pathological condition of persistent penile erection in the absence of sexual arousal or desire. It is an urological emergency and its identification is important as lack of prompt treatment can result in erectile dysfunction. The aim of this study was to estimate and describe the characteristics (number of episodes, duration, time of occurrence and evolution) of priapism in patients with sickle cell disease. A bibliographical research was carried out in PubMed, searching for papers published in the last 5 years. Thirteen scientific articles were included in this review. The main results were: 1) the highest prevalence of priapism in males reported was 48.0% and the lowest 0.67%; 2) six studies were carried out on the African Continent (46.1%), three in America (23.1%), two in Europe (15.4%) and two in Asia (15.4%); 3) the main goal of ∼50.0% of the studies was to determine the rate of priapism in patients with sickle cell disease; 4) there was predominance of sickle cell anemia patients [homozygous Hb S (HBB: c.20A>T) genotype]; 5) the minimum age of patients with priapism was 7 years old and the maximum 30 years. In general, the episodes of priapism occurred during sleep, were recurrent and had variable duration. The prevalence of priapism are not real and the explanations include underreporting by patients, lack of awareness by physicians and lack of proper prospective studies. Priapism is a complication that deserves close attention due to its significant impact on the life of the patient with sickle cell disease and, therefore, should be further clarified.
