RESUMEN El girasol (Helianthus annuus L.) es responsable del 13% de todo el aceite vegetal producido en el mundo. El desarrollo de estas plantas depende de los elementos minerales que tienen funciones esenciales y específicas en su metabolismo. En este sentido, el diagnóstico visual consiste en comparar la apariencia de una planta que recibió todos los nutrientes necesarios con una que sufrió la omisión de uno o más nutrientes. Por lo tanto, este estudio tuvo como objetivo evaluar los efectos de la ausencia de nitrógeno (N), fósforo (P), potasio (K), calcio (Ca), magnesio (Mg), azufre (S) y hierro (Fe) en el crecimiento de girasol, cultivar BRS-122, a fin de identificar y describir los síntomas visuales de la ausencia de tales nutrientes. El experimento fue conducido en invernadero y consistió en un diseño completamente al azar, con tres repeticiones y ocho tratamientos, utilizando una técnica de diagnóstico de sustracción. Los síntomas de las deficiencias fueron observados y evaluados a través de parámetros biométricos (altura de la planta, diámetro del tallo, número de hojas y área foliar), así como por aspectos visuales. La ausencia de N, P, K, Ca y Fe en la solución nutritiva afectaron severamente a las plantas de girasol, impidiendo su crecimiento vegetativo y consecuentemente su desarrollo. La interferencia negativa de la omisión del Mg en el crecimiento del girasol fue más lenta que la observada en N, P, K y Ca, con resultados más significativos a partir de los 40 días después de la siembra (DAS). La ausencia de los nutrientes dio claras evidencias de los distintos efectos que la omisión de cada elemento puede causar en los aspectos visuales de las plantas de girasol.

ABSTRACT Sunflower (Helianthus annuus L.) is responsible for 13% of all vegetable oil produced in the world. These plants’ development depends on the mineral elements that have essential and specific functions in their metabolism. In this sense, visual diagnosis consists of comparing the appearance of a plant that has received all the necessary nutrients with one that has suffered the omission of one or more nutrients. Therefore, this study aimed to evaluate the absence effects of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S) and iron (Fe) elements on the growth of sunflower, BRS-122 cultivar, in order to identify and describe the visual symptoms caused by the absence of such nutrients. The experiment was carried out in a greenhouse and consisted in a completely randomized design with three replications and eight treatments using a diagnostic subtraction technique. The symptoms of the deficiencies were observed and evaluated through biometric parameters (plant height, stem diameter, number of leaves, and leaf area) as well as by visual aspects. The absence of N, P, K, Ca and Fe in the nutrient solution severely affected the sunflower plants, preventing their vegetative growth and consequently their development. The negative interference of the Mg omission in sunflower growth was slower than the observed for nitrogen, phosphorus, potassium, and calcium giving more significant results from 40 days after sowing (DAS). The absence of nutrients gave clear evidence of the distinct effects that the omission of each element can cause on the visual aspects of sunflower plants.

Os acidentes escorpiônicos constituem um grave problema de saúde pública em países tropicais e subtropicais. Este estudo retrospectivo analisou as notificações dos acidentes escorpiônicos registrados no Sistema de Saúde do município de Campina Grande, no estado da Paraíba, de 2007 a 2012. As informações foram coletadas do banco de dados do Sistema de Informação de Agravos de Notificação do Ministério da Saúde. Foram analisadas 2283 fichas de notificação. Os dados revelaram que a maioria dos acidentados é do sexo feminino, com idade entre 20 e 29 anos. Os acidentes foram mais frequentes em área urbana, sendo os pés e as mãos os locais anatômicos do corpo mais atingidos pelas picadas. A soroterapia não foi administrada na maioria dos acidentados e as vítimas prevalentemente recorreram aos sistemas de saúde dentro do período de 1 a 3 horas após o acidente. As manifestações clínicas mais frequentes foram dor, edema e parestesias. A maioria dos acidentes foi classificada como leve, porém foram registrados 7 casos de óbito. A elevada taxa de incidência de acidentes escorpiônicos sugere que esse município pode ser uma área endêmica de escorpiões, justificando a necessidade da elaboração de estratégias de controle e prevenção de acidentes por estes animais.

Scorpion stings are a serious public health issue in tropical and subtropical countries. This is a descriptive and retrospective study of the clinical-epidemiological characteristics of scorpion sting cases registered in the Health System in the city of Campina Grande, Paraíba state, from 2007 to 2012. Data was collected from the Injury Notification Information System data banks of the Ministry of Health. A total of 2,283 records, provided by the Third Health Sector of Campina Grande, were analyzed. Data revealed that the majority of the victims are female aged between 20 and 29 years, and the highest incidence of stings was in the urban area. Victims were mostly stung on the feet and hand. Serotherapy was not administered in most cases. The majority of the victims received medical assistance within 1 to 3 hours after the sting. The most prevalent clinical manifestations were pain, edema and paresthesias. Most cases were classified as mild, though seven deaths were reported. The high incidence rate suggests that this town may be an endemic area of scorpion stings, supporting the need to develop strategies to control and prevent scorpion stings.

Background : The present study aims to investigate the clinical-epidemiological characteristics of bee sting cases recorded between 2007 and 2012 in the city of Campina Grande, Paraiba state, Brazil. Data were collected from the database of the Injury Notification Information System of the Brazilian Ministry of Health.Results : A total of 459 bee sting cases were retrospectively analyzed. The average annual incidence was 19 cases per 100,000 inhabitants. Cases were distributed in all months of the year, with higher prevalence in September and February. Most victims were men aged between 20 and 29 years. The highest incidence of cases was recorded in urban areas. Victims were stung mainly on the head and torso and received medical assistance predominantly 1 to 3 hours after being stung. The most frequent clinical manifestations were pain, edema and itching. Most cases were classified as mild, and three deaths were reported.Conclusions : The high incidence of envenomations provoked by bees in Campina Grande suggests that it may be an important risk area for accidents. Since several medical records lacked information, clinical-epidemiological profile of bee sting cases in the studied region could not be accurately determined. The current study provides relevant data for the development of strategies to promote control and prevention of bee stings in this area. Further training for health professionals seems to be necessary to improve their skills in recording clinical-epidemiological information as well as in treating bee sting victims.

Introduction This study investigated the epidemiological and clinical profile of snakebite cases reported from 2007 to 2012 in the municipalities of the Curimataú region, State of Paraíba, in northeastern Brazil. Methods Data were collected from the Health Department of the State of Paraíba using the Injury Notification Information System data banks of the Health Ministry. Results A total of 304 snakebite cases were studied. The cases occurred most frequently from April to June. The genera Bothrops, Crotalus, and Micrurus were responsible for 74.6%, 6.2%, and 1.3% of cases, respectively. Snakebite cases predominated in males living in rural areas and between 10 and 19 years old. The highest incidence of bites occurred on the feet. The majority of the victims received medical assistance within 1 to 3h after being bitten. With regard to severity, 48% of the cases were classified as mild, 26% as moderate, and 2.6% as severe. Successful cures predominated, and no deaths were reported. The average antivenom ampoule dose used for the treatment in some snakebite cases was lower than that recommended by the Health Ministry. Conclusions Although our results show that Paraíba has a good level of medical care, there are serious deficiencies in recording snakebite information. These data indicate the need to improve the recording process for snakebite cases. Further training for health professionals seems to be necessary to optimize their skills in treating snakebite victims.
