Abstract: Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

Reasons for Prophylactic Mastectomy in Women Carrying BRCA 1/2 Mutation: A Systematic Literature Review  [PDF]
Manuel Machado, Sofia Braga
Advances in Breast Cancer Research (ABCR) , 2013, DOI: 10.4236/abcr.2013.23017
Abstract:

Although the majority of breast cancers are sporadic, it is estimated that between 5% and 10% of cases are hereditary and mostly associated with BRCA 1 and BRCA 2 mutations. Women with BRCA 1 or BRCA 2 mutation present up to 95% increased risk of breast cancer and are advised to take preventive measures. Surveillance, chemoprevention and prophylactic surgery (mastectomy and oophorectomy) are risk-reducing strategies. This literature review aims to respond to two major questions: 1) to what extent is the decision-making for prophylactic mastectomy in women with the BRCA mutation a more relevant option than other strategies, and 2) what are the major factors influencing the decision for mastectomy? For this purpose, 27 published articles were reviewed. Results show: a) the decision for mastectomy is more frequent in women carrying BRCA 1/2 mutation than in non-carriers; mastectomy being less frequent than oophorectomy; b) the decision-making is significantly associated with BRCA mutation, parity, age and family history; c) reasons underlying women decision-making relate to anxiety toward the risk of cancer, concerns with surgery, body-image and sexuality. It is discussed that, due to the complexity of the decision-making process, these cases require a careful and meticulous approach regarding information provided, and in addressing concerns.

Abstract: Background: Although few fungal species are considered to be pathogenic to humans and even when they are commonly less relevant than bacteria or viruses, they are not insignificant as a cause of disease. From a practical point of view, it was found that the mycosis fungoides they cause is one of the first reasons for consultation in our country and the world. Objective: To determine the main clinical and epidemiological features and laboratory findings of pediatric patients affected by ringworm. Methods: A descriptive, case series study was conducted. It included 102 patients with dermatophytosis. The information about these patients was collected from medical records and laboratory results of scraping and cultures of the lesions. Results: We obtained more positives in the test by culture (70.59%), compared to a 66, 7% in the examination by scraping, being Trichophyton rubrum the most common causative agent in the nails and body. The age group from 15 years old on predominated, as well as white skinned and female patients. Most patients were infected through contact with dogs. Conclusions: The percentage of pediatric patients with dermatophytosis is not low. This remains a frequent cause of medical consultation Fundamento: a pesar de que pocas especies de hongos son patógenos para los humanos y aun cuando su importancia es menor que las de las bacterias o los virus, no son insignificantes como causa de enfermedades. Desde el punto de vista práctico se ha comprobado que las micosis que estos causan representan uno de los primeros motivos de consulta dermatológica en nuestro país y el mundo. Objetivo: determinar las principales características clínico-epidemiológicas y de laboratorio de pacientes en edad pediátrica afectados por dermatofitosis. Métodos: estudio descriptivo, de serie de casos que incluyó 102 pacientes con diagnóstico de dermatofitosis cuya información fue recogida de historias clínicas y en el laboratorio al realizarse raspado y cultivo de las lesiones. Resultados: se obtuvo mayor positividad en el examen por cultivo (70,59 %), frente a 66, 7 % en el examen por raspado; el Trichophyton rubrum fue el agente causal más frecuente en las u as y en el cuerpo, predominó en el grupo de 15 a os y más, en los pacientes de color de piel blanca y en las féminas. La mayoría de los pacientes se infectaron a través del contacto con canes. Conclusiones: no son bajos los por cientos de pacientes pediátricos con dermatofitosis, la cual continúa siendo causa frecuente de consulta médica
