Abstract: As we find ourselves in the beginning of a new millennium, we are faced with challenges to our survival as a human population. Some of the greatest threats to our survival are sweeping epidemics that affect millions of individuals worldwide. Drug addiction, although often regarded as a personality disorder, may also be seen as a worldwide epidemic with evolutionary genetic, physiological, and environmental influences controlling this behavior. Globally, the use of drugs has reached all-time highs. On average, drug popularity differs from nation to nation. The United Nations Office on Drugs and Crime identified major problem drugs on each continent by analyzing treatment demand [1]. From 1998 to 2002, Asia, Europe, and Australia showed major problems with opiate addiction, South America predominantly was affected by cocaine addiction, and Africans were treated most often for the addiction to cannabis. Only in North America was drug addiction distributed relatively evenly between the use of opiates, cannabis, cocaine, amphetamines, and other narcotics. However, all types of drugs are consumed throughout each continent. Interpol reported over 4000 tons of cannabis were seized in 1999, up 20% from 1998, with the largest seizures made in Southern Africa, the US, Mexico, and Western Europe [2]. Almost 150 tons of cocaine is purchased each year throughout Europe and in 1999 opium production reached an estimated 6600 tons, the dramatic increase most likely due to a burst of poppy crops throughout Southwest Asia. This rapid increase in drug use has had tremendous global effects, and the World Health Organization cited almost 200,000 drug-induced deaths alone in the year 2000 [3]. The Lewin group for the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism estimated the total economic cost of problematic use of alcohol and drugs in the United States to be $245.7 billion for the year 1992, of which $97.7 billion was due to drug abuse [4].
Immunopathogenesis of brain abscess

Journal of Neuroinflammation , 2004, DOI: 10.1186/1742-2094-1-16
Abstract: Brain abscesses develop in response to a parenchymal infection with pyogenic bacteria, beginning as a localized area of cerebritis and evolving into a suppurative lesion surrounded by a well-vascularized fibrotic capsule. The leading etiologic agents of brain abscess are the streptococcal strains and S. aureus, although a myriad of other organisms have also been reported [1,2]. Brain abscess represents a significant medical problem, accounting for one in every 10,000 hospital admissions in the United States, and remains a serious situation despite recent advances made in detection and therapy [2]. In addition, the emergence of multi-drug resistant strains of bacteria has become a confounding factor. Following infection, the potential sequelae of brain abscess include the replacement of the abscessed area with a fibrotic scar, loss of brain tissue by surgical excision, or abscess rupture and death. Indeed, if not detected early, an abscess has the potential to rupture into the ventricular space, a serious complication with an 80% mortality rate [1]. The most common sources of brain abscess are direct or indirect cranial infection arising from the paranasal sinuses, middle ear, and teeth. Other routes include seeding of the brain from distant sites of infection in the body (i.e. endocarditis) or penetrating trauma to the head. Following brain abscess resolution patients may experience long-term complications including seizures, loss of mental acuity, and focal neurological defects that are lesion site-dependent.At the histological level, brain abscess is typified by a sequential series of pathological changes that have been elucidated using the experimental rodent models described in detail below [3-7]. Staging of brain abscess in humans has been based on findings obtained during CT or MRI scans. The early stage or early cerebritis occurs from days 1–3 and is typified by neutrophil accumulation, tissue necrosis, and edema. Microglial and astrocyte activation is also e

Abstract: This cross-cultural study examines instructor nonverbal immediacy in Chilean and Russian English classrooms and its relationship to Foreign Language Anxiety. Participants included 84 undergraduate university students (33 Chilean students enrolled at a small state university in Northern Chile; and 51 Russian students enrolled at a large state university in Moscow). Results indicate that: (a) Chilean students receiving instruction from Chilean professors perceive a significantly greater amount of instructor nonverbal immediacy than Russian students who receive instruction from Russian instructors; (b) Chilean students self-reporte significantly higher levels of Foreign Language Anxiety than their Russian counterparts; and (c) Foreign Language Anxiety is only slightly negatively correlated with one nonverbal teacher immediacy item in the Russian population and is not correlated with any items in the Chilean sample. Conclusions focus on the important role that culture plays in classroom language teaching and the implications for teacher training. Este análisis transcultural estudia los gestos de inmediatos en las clases de inglés en Chile y Rusia y su relación con la ansiedad en los idiomas extranjeros. Los participantes fueron 84 estudiantes universitarios de pregrado (33 chilenos matriculados en una peque a universidad estatal en el norte chileno y 51 estudiantes rusos matriculados en una universidad grande en Moscú). Los resultados indican que: a) los estudiantes chilenos que recibieron clases de profesores chilenos percibieron muchos más gestos inmediatos que los estudiantes rusos que recibieron clases de profesores rusos; b) los estudiantes chilenos revelan niveles muchos más altos de ansiedad en el aprendizaje de idiomas extranjeros que sus homólogos rusos; y c) la ansiedad muestra una leve correlación negativa con un ítem de los gestos del profesor en la población rusa y no está correlacionada con ningún ítem en los ejemplos chilenos. Las conclusiones se centran en la importancia del papel que tiene la cultura en las clases de idiomas extranjeros y las implicaciones para la formación docente.

Avalia??o de qualidade de vida em portadores de blefaroptose
Asano, Márcia Emiko;Osaki, Midori Hentona;
Arquivos Brasileiros de Oftalmologia , 2006, DOI: 10.1590/S0004-27492006000400016
Abstract: purpose: to assess the health-related quality of life in blepharoptosis patients and the impact after surgical management on their quality of life. methods: twenty-one patients with congenital or acquired blepharoptosis completed a questionnaire which was adapted from the visual function questionnaire (vfq), before and after surgical management. results: mean preoperative score was 74 and mean postoperative score was 81 and there was a statistically significant difference between mean pre- and postoperative scores of 7 (p=0.004). there was a statistically significant difference only for the mental health subdomain (p=0.001) in the evaluation of the questions (a=0.002) and subdomains (a=0.004). conclusion: the quality of life in blepharoptosis patients was significantly better after surgical management in the assessment using the vfq. the outcomes emphasize the need for of using questionnaires designed specifically for this disease.
Qualidade de vida e custos diretos em pacientes com blefaroespasmo essencial e espasmo hemifacial, tratados com toxina botulínica-A
Osaki, Midori Hentona;Belfort Jr, Rubens;
Arquivos Brasileiros de Oftalmologia , 2004, DOI: 10.1590/S0004-27492004000100008
Abstract: purpose: to evaluate both the costs and the impact on the quality of life of essential blepharospasm and hemifacial spasm patients treated with botulinum toxin-a. methods: 28 patients (16 essential blepharospasm and 12 hemifacial spasm), treated with btx-a, were evaluated by means of two research tools, namely medical outcomes study short form healthy survey, and fahn disability rating scale. the costs were mainly calculated on the basis of the toxin units used by each patient during a one-year period. results: the total estimated direct cost was estimated at 1,081.62 reais per year (±89.39) for essential blepharospasm and 618.06 reais per year (±60.06) for hemifacial spasm, at an outpatient level (p<0.001). before treatment all domains of sf-36 were significantly worse in both diseases. under effective treatment with botulinum toxin-a the increases in the indices of sf-36 show changes in the general health rates of the population under study, with a statistically significant difference between the pre and post answers (p<0.05). in relating sf-36 with the fahn disability rating scale, the essential blepharospasm cases showed significant positive relationships (functional capacity, general health, emotional aspect and social aspects) while in the hemifacial spasm patients no correlation was found. conclusion: the present study demonstrates a remarkable negative impact of both diseases on the quality of life of essential blepharospasm and hemifacial spasm patients, as well as a significant improvement of both diseases after botulinum toxin-a treatment. furthermore, the research data seem to justify the high costs of botulinum toxin-a treatment in view of its considerable benefits regarding the patients' quality of life.
