Tics in children and adolescents: a retrospective analysis of 78 cases
Introducción
Los tics son el trastorno del movimiento más frecuente
en la edad pediátrica. Es común la existencia de historia familiar
de tics y de antecedentes familiares y personales de
trastornos neurocomportamentales. Los tics pueden comprometer
de modo importante las actividades de la vida
diaria del individuo.
Objetivo
Estudio de las características de los tics de niños y adolescentes
de la Consulta de Neuropediatría del Hospital Geral
de Santo António.
Materiales y métodos
Análisis retrospectivo de los casos de tics usando la información
recogida de las respectivas historias clínicas. Se
utilizaron los criterios del Manual diagnóstico y estadístico
de los trastornos mentales en su cuarta revisión de textos
(DSM-IV-TR) de 2000, de la Asociación Americana de
Psiquiatría.
Resultados
Fueron analizadas las historias clínicas de 78 individuos,
84,6 % de los cuales eran del sexo masculino. Más de un
tercio de los casos pertenecía al grupo etario de los 4 a
los 8 años de edad. En el 5,1% los tics se iniciaron antes
de los 2 años. Historia familiar de tics, depresión y trazos
de enfermedad obsesivo-compulsiva ocurrieron en
aproximadamente un 30 % de los casos. La comorbilidad
más frecuente fue el trastorno por déficit de atención e
hiperactividad (TDAH) (67,9%). Se verificó la posible ocurrencia
de trastorno neuropsiquiátrico autoinmune pediátrico
(PANDAS) en 5 casos. Los tics motores precedieron a
los vocales en todos los casos. En más de dos tercios los
tics eran simples. En el 59,0 % de los casos los tics eran
crónicos, y el 45,7 % de éstos cumplían criterios de trastorno
de Gilles de la Tourette. El 43,1 % de los individuos
con tics crónicos habían sido medicados, la mayoría con
risperidona.
Conclusiones
De un modo general los resultados de este estudio son
concordantes con los descritos en la literatura especializada,
subrayándose la necesidad de considerar el diagnóstico
en edades precoces, y señalándose la importancia de identificación
y terapéutica adecuada de las comorbilidades.Introduction
Tics are the most frequent abnormal movement in children.
A familial history of tics and a personal and familial
history of neurobehavioral disturbances are common in
children with this abnormality. Tics may seriously compromise
daily activities in affected individuals.
Objective
To identify the characteristics of tics in children and
adolescents followed-up in the Neuropediatric Unit of the
Hospital Geral de Santo António.
Materials and methods
We performed a retrospective analysis of patients with
tics based on information collected from medical records.
The diagnostic criteria of the DSM IV-TR 2000 of the American
Psychiatric Association were used.
Results
The medical records of 78 children were analyzed,
84.6% of whom were boys. More than one third of the patients were aged 4 to 8 years old. In 5.1% of the patients
tics developed before the age of 2 years. A familial history
of tics, depression and obsessive disorder traits was found
in approximately 30 % of patients. The most frequent comorbidity
was attention deficit hyperactivity disorder
(67.9 %). The occurrence of pediatric autoimmune neuropsychiatric
disorders associated with streptococcus infection
(PANDAS) was suggested in five patients. In all patients,
motor tics occurred before vocal tics. In more than
two thirds of the patients, tics were simple. In 59.0% of
the patients, tics were chronic, and in 45.7% of these met
the criteria for Tourette’s syndrome. A total of 43.1% of
the patients with chronic tics received pharmacotherapy,
risperidone being the most frequently used drug.
Conclusions
In general the results of the present study are in agreement
with those of previous studies, underlining the need
to consider a diagnosis of tics in young children and highlighting
the importance of identification and appropriate
treatment of comorbidities

Malignant mammary tumor in female dogs: environmental contaminants
Mammary tumors of female dogs have greatly increased in recent years, thus demanding rapid diagnosis and effective treatment in order to determine the animal survival. There is considerable scientific interest in the possible role of environmental contaminants in the etiology of mammary tumors, specifically in relation to synthetic chemical substances released into the environment to which living beings are either directly or indirectly exposed. In this study, the presence of pyrethroid insecticide was observed in adjacent adipose tissue of canine mammary tumor. High Precision Liquid Chromatography - HPLC was adapted to detect and identify environmental contaminants in adipose tissue adjacent to malignant mammary tumor in nine female dogs, without predilection for breed or age. After surgery, masses were carefully examined for malignant neoplastic lesions. Five grams of adipose tissue adjacent to the tumor were collected to detect of environmental contaminants. The identified pyrethroids were allethrin, cyhalothrin, cypermethrin, deltamethrin and tetramethrin, with a contamination level of 33.3%. Histopathology demonstrated six female dogs (66.7%) as having complex carcinoma and three (33.3%) with simple carcinoma. From these tumors, seven (77.8%) presented aggressiveness degree III and two (22.2%) degree I. Five tumors were positive for estrogen receptors in immunohistochemical analysis. The contamination level was observed in more aggressive tumors. This was the first report in which the level of environmental contaminants could be detected in adipose tissue of female dogs with malignant mammary tumor, by HPLC. Results suggest the possible involvement of pyrethroid in the canine mammary tumor carcinogenesis. Hence, the dog may be used as a sentinel animal for human breast cancer, since human beings share the same environment and basically have the same eating habits

Neuromyelitis Optica Spectrum Disorders: a Nationwide Portuguese Clinical Epidemiological Study
Introduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits.
Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics.
Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients were included.
Results: A total of 180 patients met the 2015 Wingerchuk NMOSD criteria, 77 were AQP4-antibody positive (Abs+), 67 MOG-Abs+, and 36 seronegative. Point prevalence on December 31, 2018 was 1.71/100,000 for NMOSD, 0.71/100,000 for AQP4-Abs+, 0.65/100,000 for MOG-Abs+, and 0.35/100,000 for seronegative NMOSD. A total of 44 new NMOSD cases were identified during the two-year study period (11 AQP4-Abs+, 27 MOG-Abs+, and 6 seronegative). The annual incidence rate in that period was 0.21/100,000 person-years for NMOSD, 0.05/100,000 for AQP4-Abs+, 0.13/100,000 for MOG-Abs+, and 0.03/100,000 for seronegative NMOSD. AQP4-Abs+ predominated in females and was associated with autoimmune disorders. Frequently presented with myelitis. Area postrema syndrome was exclusive of this subtype, and associated with higher morbidity/mortality than other forms of NMOSD. MOG-Ab+ more often presented with optic neuritis, required less immunosuppression, and had better outcome.
Conclusion: Epidemiological/clinical NMOSD profiles in the Portuguese population are similar to other European countries.info:eu-repo/semantics/publishedVersio
Valores de referência para plumbemia em população urbana
INTRODUCTION: The lead reference values for blood used in Brazil come from studies conducted in other countries, where socioeconomic, clinical, nutritional and occupational conditions are significantly different. In order to guarantee an accurate biomonitoring of the population which is occupationally exposed to lead, a major health concern of the studied community, reference values for individuals who are not occupationally exposed and who live in the southern region of the city were established. MATERIAL AND METHOD: The sample was composed of 206 subjects of at least 15 years of age. Various strategies were employed to assure good-quality sampling. Subjects who presented values outside clinical or laboratory norms were excluded, as well as those whose specific activities might interfere with the results. RESULTS: Lead reference values for blood were found to be from 2.40 to 16.6 µg.dL-1, obtained by the interval ; ± 2s (where ; is the mean and s is the standard deviation form observed values) and the median was 7.9 µg.dL-1.INTRODUÇÃO: Os valores de referência utilizados no Brasil, para chumbo em sangue, advêm de estudos realizados em outros países onde as condições socioeconômicas, clínicas, nutricionais e ocupacionais diferem bastante das brasileiras. Para garantir uma correta biomonitorização da população ocupacionalmente exposta ao chumbo, um dos principais problemas identificados no município estudado, foram estabelecidos valores de referência na população não exposta ocupacionalmente da região sul do município. MATERIAL E MÉTODO: Diferentes estratégias foram utilizadas para assegurar a qualidade de amostragem, que foi dimensionada em 206 sujeitos acima de 15 anos. Sujeitos que apresentaram valores clínicos e laboratoriais fora da faixa de normalidade foram excluídos, bem como os que apresentaram atividades específicas que pudessem interferir nos valores de plumbemia. RESULTADOS: Foram encontrados valores de referência para chumbo em sangue de 2,4 a 16,6 mg.dL-1, obtidos através do intervalo ; ± 2s (onde ; é o valor médio e s é o desvio-padrão dos valores observados) e mediana = 7,9 µg.dL-1
Os mártires e a cristianização do território na América portuguesa, séculos XVI e XVII
O artigo investiga um grupo de atores sociais bastante relevante para viabilizar a cristianização na América portuguesa: os mártires cristãos, indivíduos muito especiais, dispostos a regar a terra com seu próprio sangue, de forma a tornar definitiva e irreversível a ocupação cristã do território. Os mártires - e principalmente a narrativa em torno deles - parecem ter sido bastante acionados para integrar a América portuguesa e seus habitantes nativos à temporalidade e territorialidade cristã. Os mártires dos séculos XVI e XVII, principalmente missionários, reeditavam os martírios do início da cristandade, que espalharam o cristianismo rumo a diversas partes do mundo na antiguidade. Dessa forma, viabilizaram a cristianização das novas fronteiras, consagrando o solo com seu sangue divino e viabilizando posteriores processos de urbanização. Além da função estratégica dos mártires para os cristãos, o texto mostra que eles também tiveram significado peculiar na interlocução com as culturas ameríndias, que tinha como um de seus principais personagens o grande guerreiro, disposto a perder seu sangue em prol de seu grupo.This paper looks into a group of social agents who played a significant role in the Christianization of Portuguese America, namely, the Christian martyrs - very special individuals who were ready to wet the land with their own blood in order to make possible a definitive and irreversible occupation of the territory by Christian settlers. The martyrs, and above all the stories told about them, seem to have been called upon to integrate Portuguese America and its native inhabitants into the temporalities and territory of Christendom. Mostly made up of missionaries, this group of 16th and 17th-century martyrs reedited the martyrdom of early Christians, who spread their creed across numerous parts of the Ancient World. They enabled the Christianization of new frontiers by consecrating the soil with their divine blood and paving the way for subsequent processes of urban development. In addition to their strategic significance for Christianity, the text also shows that their martyrdom played a specific role in the Christian settlers' interaction with Amerindian culture, whose main cults included the figure of the great warrior, ever ready to shed his own blood for his group
