Complications of otitis media - a potentially lethal problem still present / Complicações das otites média - um problema potencialmente letal ainda presente

ABSTRACT INTRODUCTION: It is an erroneous but commonly held belief that intracranial complications (ICCs) of chronic and acute otitis media (COM and AOM) are past diseases or from developing countries. These problems remain, despite improvements in antibiotic care. OBJECTIVE: This paper analyzes the occurrence and clinical characteristics and course of the main ICCs of otitis media (OM). METHODS: Retrospective cohort study of 51 patients with ICCs from OM, drawn from all patients presenting with OM to the emergency room of a large inner-city tertiary care hospital over a 22-year period. RESULTS: 80% of cases were secondary to COM of which the incidence of ICC was 0.8%; 20% were due to AOM. The death occurrence was 7.8%, hearing loss in 90%, and permanent neurological sequelae in 29%. Patients were 61% male. In the majority, onset of ear disease had occurred during childhood. Delay of diagnosis of both the initial infection as well as the secondary ICC was significant. ICCs included brain abscess and meningitis in 78%, and lateral sinus thrombosis, empyema and otitic hydrocephalus in 13%, 8% and 1% of cases, respectively. Twenty-seven neurosurgical procedures and 43 otologic surgery procedures were performed. Two patients were too ill for surgical intervention. CONCLUSION: ICCs of OM, although uncommon, still occur. These cases require expensive, complex and long-term inpatient treatment and frequently result in hearing loss, neurological sequelae and mortality. It is important to be aware of this potentiality in children with COM, especially, and maintain a high index of suspicion in order to refer for otologic specialty care before such complications occur.

Resumo Introdução: É uma crença comum, porém errônea, que complicações intracranianas (CICs) de otite média tanto aguda (OMA) quanto crônica (OMC) sejam doenças do passado ou de países em desenvolvimento. No entanto, esses problemas continuam, apesar de melhorias na terapia antimicrobiana. Objetivo: Analisar a ocorrência, as características clínicas e a evolução das principais CICs secundárias às otites médias (OM) Método: Estudo de coorte retrospectivo de 51 pacientes com CIC secundárias a OM, provenientes do pronto-socorro de um Hospital Universitário ao longo de um período de 22 anos. Resultado: No total, 80% dos casos de CICs foram secundários a OMC, cuja incidência foi de 0,8%, e apenas 20% foram secundárias a OMA. A letalidade foi de 7,8%, perda auditiva em 90%, com sequela neurológica permanente em 29%. Dentre os pacientes, 61% eram do sexo masculino. Na maioria, o início da doença otológica tinha ocorrido durante a infância. A demora no diagnóstico, tanto da infecção primária como da complicação secundária, foi significativa. CICs, incluindo abscesso cerebral e meningite, corresponderam a 78%, e trombose do seio lateral, empiema e hidrocefalia otítica em 13%, 8% e 1% dos casos, respectivamente. Foram realizados 27 procedimentos neurocirúrgicos e 43 cirurgias otológicas. Dois pacientes não apresentavam condições clínicas para a intervenção cirúrgica Conclusão: CICs de OM, embora incomuns, ainda ocorrem. Esses casos exigem tratamento hospitalar oneroso, complexo e de longo prazo, e frequentemente resultam em perda auditiva, sequelas neurológicas e mortalidade. É importante estar ciente dessa potencialidade especialmente em crianças com OMC e manter um alto índice de suspeita, encaminhar para avaliação otológica e antecipar a ocorrências de tais complicações.

Caracterización sociodemográfica y clínica de la población atendida en el Instituto Teletón de Santiago / Sociodemographic and clinical characteristic of the population attended in the Instituto Teletón de Santiago

Los Institutos Teletón atienden al 85% de la población infantil chilena con discapacidad neuro-músculo-esquelética, concentrando el mayor porcentaje de esta población. Sin embargo, no existen registros que permitan caracterizar esta población. Objetivo: Caracterizar la población de pacientes atendidos en el Instituto Teletón de Santiago durante el año 2012. Pacientes y método: Se analizaron las características sociodemográficas de los registros electrónicos del Instituto Teletón de Santiago de los pacientes activos que se atendieron durante el año 2012. Resultados: Durante el año 2012 se atendió un total de 8.959 pacientes en el Instituto Teletón de Santiago. En relación con el nivel socioeconómico, un 33,3% de estos correspondieron a extrema pobreza, y un 28,7% a nivel medio bajo. Con respecto a los diagnósticos clínicos principales se encontró que la parálisis cerebral y otras encefalopatías que también llevan a discapacidad motora concentran el 55,4% de los casos. Conclusiones: Como producto de esta caracterización, sería adecuado fomentar la necesidad de optimizar el registro nacional de la población infantil con discapacidad y sus características particulares, para así poder tomar decisiones de políticas públicas, como destinación de fondos o programas de apoyo.

The Institutos Teletón care for 85% of the Chilean child population with neuromusculoskeletal disability, the large percentage concentrating in this population. However, there are no registers that enable a profile to be determined on this population. Objective: To determine the profile of patients attending the Instituto Teletón de Santiago during the year 2012. Patients and method: The sociodemographic characteristics were analyzed from the computerised records of the Instituto Teletón de Santiago on active patients who were seen during the year 2012. Results: A total of 8,959 patients were seen during the study year in the Instituto Teletón de Santiago. As regards socioeconomic level, 33.3% were in extreme poverty, 28.7% to low-middle level. The main clinical diagnoses were cerebral palsy and other encephalopathies that also lead to motor disability, and accounted for 55.4% of the cases. Conclusions: As a result of determining this profile, it would be appropriate to encourage the need for a national register of the child population with disability, as well as their particular characteristics in order to make decisions on public policy, as a destination for funds or support programs.

Monitoring of parasitic cysts in the brains of a flock of sheep in Egypt / Monitoramento de cistos parasitários no cérebro de um rebanho de ovinos no Egito

Cerebral parasitic cysts constitute a major problem for livestock. Among these, coenurosis and toxoplasmosis are predominant. Here, a total number of 60 sheep obtained from a private farm in Suez province, Egypt, were examined postmortem to detect visible parasitic cysts, and microscopically to detect small-sized entities. Necropsy revealed bladder-like cysts measuring 0.5-6.5 cm in diameter that were filled with a translucent fluid containing a large number of protoscolices. Accordingly, the cysts were identified as the metacestode Coenurus cerebralis. Among the sheep examined, 11 animals (7 males and 4 females) (18.3%) were infected. Most of the cysts were located in the cerebral hemispheres, with numbers ranging from one to three per infected animal. The effect of the presence of cysts in the brain tissue was evaluated. Histopathologically, pseudocysts of the apicomplexan Toxoplasma gondii were found in two animals with no detectable inflammatory cell reactions. In conclusion, coenurosis and toxoplasmosis are serious parasitic problems that play a significant role in sheep management in Egypt, as a result of close contact between livestock and dogs and cats, which play a critical role in the life cycle of these parasites.

Cistos cerebrais parasitários constituem um grande problema para o gado. Entre estes, coenurosis e toxoplasmose são predominantes. Aqui, um número total de 60 ovelhas obtidas em uma fazenda particular na província Suez, Egito, foram examinadas post-mortem para a detecção de cistos parasitários visíveis e microscopicamente para detectar cistos de pequenas dimensões. A necropsia revelou cistos medindo entre 0,5-6,5 cm de diâmetro, preenchidos com um fluido transparente, contendo um grande número de protoscolices. Por conseguinte, os cistos foram identificados como o metacestóide Coenurus cerebralis. Entre as ovelhas examinadas, 11 animais (7 machos e 4 fêmeas) (18,3%) estavam infectados. A maior parte dos cistos estavam localizados nos hemisférios cerebrais, com números variando de um a três em ovinos infectados. O efeito da presença de cistos no tecido do cérebro foi avaliado. Histopatologicamente, pseudocistos de Toxoplasma gondii foram encontrados em dois animais sem reações inflamatórias detectáveis. Em conclusão, coenurosis e toxoplasmose são graves problemas parasitários que desempenham um papel significativo no manejo de ovelhas no Egito, como resultado do contacto íntimo dos animais com os cães e gatos, que desempenham um papel crítico no ciclo de vida desses parasitas.

Paracoccidioidomycosis case series with and without central nervous system involvement / Série de casos de paracoccidioidomicose com e sem envolvimento do sistema nervoso central

INTRODUCTION: Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS: A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS: Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS: The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.

INTRODUÇÃO: A paracoccidioidomicose (PCM) é a micose profunda mais importante na América do Sul. O comprometimento do sistema nervoso central é grave e pode ocorrer em 12,5% dos casos. Este trabalho tem como objetivo descrever oito casos de neuroparacoccidioidomicose (NPMC) e comparar suas características com pacientes sem envolvimento neurológico, a fim de identificar aspectos singulares da NPCM. MÉTODOS: Uma coorte de 213 casos de PCM foi avaliada na Clínica de Doenças Infecciosas do Hospital das Clínicas da Universidade Federal de Minas Gerais, de outubro de 1976 a agosto de 2008. Dados epidemiológicos, clínicos, laboratoriais, terapêuticos e de seguimento foram registrados. RESULTADOS: Oito pacientes apresentaram NPCM. A prevalência de NPCM observada foi de 3,8%. Um paciente apresentou a forma subaguda da PCM e sete apresentaram a forma crônica. Todos os pacientes apresentaram a forma parenquimatosa. Cerca de 60% dos pacientes provenientes das regiões norte e nordeste de Minas Gerais desenvolveram NPCM. Foi observado o desenvolvimento de NPCM em uma mãe e em seu filho. Os pacientes com NPCM apresentaram perfis demográficos e clínicos similares à descrição da literatura. Quando comparados aos pacientes com PCM, houve diferenças em relação à procedência de tais pacientes e história familiar positiva de PCM. CONCLUSÕES: Os resultados confirmam a importância da avaliação neurológica em pacientes com PCM. Apesar das limitações desse trabalho, as diferenças com relação à procedência dos pacientes e à história familiar apontam para a necessidade de mais estudos para investigar a existência de fatores de susceptibilidade envolvidos no desenvolvimento da NPCM.

Encefalopatia hereditária em bovinos no estado do Espírito Santo / Hereditary encephalopaty of cattle in Espírito Santo state, Brazil

Descrevem-se os aspectos epidemiológicos e clínico-necroscópicos de uma doença neurológica hereditária observada em bovinos no município de Ecoporanga, norte do Estado do Espírito Santo. Trata-se de enfermidade do sistema nervoso central verificada exclusivamente em fêmeas, filhas de touro reprodutor de 5 anos de idade da raça Nelore, oriundo do município de Curvelo, Minas Gerais, com vacas mestiças Nelore x Quianini; bezerros machos oriundos deste cruzamento não demonstraram quaisquer sinais relacionados à enfermidade. Os sinais clínicos, presentes ao nascimento ou detectáveis nas primeiras semanas de vida, caracterizam-se por ataxia, perda do equilíbrio, instabilidade, andar em círculos, posicionamento incorreto dos membros no animal em estação ou em marcha (afastamento e/ou desvio de membros da posição normal) e desvio lateral da coluna (eixo principal do corpo em diagonal). De animal para animal, há marcada variação na intensidade das manifestações clínicas. Os bovinos mais afetados morrem devido à incapacidade de se alimentar. O exame macroscópico evidenciou, em grau variável de intensidade, áreas de depressão assimétrica setorial, sobretudo nos lobos frontal e temporal do córtex telencefálico e no córtex cerebelar. Em adição observou-se atrofia de grupos musculares de membros correspondentes às porções defeituosas no sistema nervoso central. O estudo histológico inicial revelou que as áreas deprimidas devem-se à redução setorial de populações neuronais (provavelmente abiotrofia/atrofia) principalmente nos lobos cerebrais frontal e temporal e nas camadas granular e molecular do córtex cerebelar. Estudos morfométrico, imunohistoquímico e ultraestrutural estão sendo realizados e devem trazer mais informações sobre os aspectos microscópicos e patogenéticos. Os achados epidemiológicos indicam que a enfermidade está diretamente ligada ao cromossoma X, com penetrância completa e expressividade variável.

The epidemiological, clinical and pathological aspects of a neurological disease have been described in cattle in the Ecoporanga county, northeastern Espírito Santo, Brazil. This disease of the central nervous system occurred only in daughters of a 5-year-old Nelore bull crossed with Nelore x Quianini cows. The clinical signs, which were detectable immediately or in the first weeks after birth, are characterized by ataxia, instability, circling, abnormal position of the limbs when standing or walking (removal and/or deviation of members from the normal position) and lateral deviation of the vertebral column (main axis of the body in diagonal). The disease is expressed by variable widths in their clinical manifestations. Most affected animals died due to incapacity of milk or food intake. The macroscopic examination shows variable degree of asymmetric sectorial depressed areas of the frontal and temporal telencephalic cortex, and in the cortex of the cerebellum, as well as correspondent muscular (appendicular) atrophy. Histological examination revealed that the depressed areas are due to the sectorial reduction of neuronal populations (probably atrophy/abiotrophy), mainly in the frontal and temporal brain lobes, and in the molecular and granular layers of the cerebellar cortex. Morphometric, immunohistochemical and ultrastructural studies are underway and should provide more information about the microscopical and pathogenetic aspects. Epidemiological data indicate that the illness is directly linked to the chromosome X, with complete penetration and variable expressiveness.

Temporal pole signal abnormality on MR imaging in temporal lobe epilepsy with hippocampal sclerosis: a fluid-attenuated inversion-recovery study

OBJECTIVE: To determine the frequency and regional involvement of temporal pole signal abnormality (TPA) in patients with hippocampal sclerosis (HS) using fluid-attenuated inversion-recovery (FLAIR) MR imaging, and to correlate this feature with history. METHOD: Coronal FLAIR images of the temporal pole were assessed in 120 patients with HS and in 30 normal subjects, to evaluate gray-white matter demarcation. RESULTS: Ninety (75 percent) of 120 patients had associated TPA. The HS side made difference regarding the presence of TPA, with a left side prevalence (p=0.04, chi2 test). The anteromedial zone of temporal pole was affected in 27 (30 percent) out of 90 patients. In 63 (70 percent) patients the lateral zone were also affected. Patients with TPA were younger at seizure onset (p=0.018), but without association with duration of epilepsy. CONCLUSION: Our FLAIR study show temporal pole signal abnormality in 3/4 of patients with HS, mainly seen on the anteromedial region, with a larger prevalence when the left hippocampus was involved.

OBJETIVO: Determinar a freqüência e o envolvimento regional da anormalidade de sinal do pólo temporal (APT) em pacientes com esclerose hipocampal (EH) utilizando seqüência inversão recuperação com supressão da água (FLAIR) por RM, e correlacioná-la com a história. MÉTODO: Foram analisadas as imagens coronais FLAIR dos pólos temporais de 120 pacientes com EH e de 30 indivíduos normais, para avaliar a demarcação entre substâncias branca e cinzenta. RESULTADOS: Noventa (75 por cento) dos 120 pacientes tinham APT associada. Houve prevalência do lado esquerdo (p=0.04, chi2 teste) na relação entre APT e o lado da EH. A zona ântero-medial estava acometida em 27 (30 por cento) destes pacientes. Em 63 (70 por cento) pacientes também a zona lateral estava acometida. Pacientes com APT apresentaram início da epilepsia quando mais jovens (p=0.018), porém sem associação com a sua duração. CONCLUSÃO: A seqüência FLAIR mostra haver ATP em 3/4 dos pacientes com EH, principalmente na região ântero-medial, com maior prevalência quando o hipocampo esquerdo estava envolvido.

Recurrent annual outbreaks of a hepato-myo-encephalopathy syndrome in children in western Uttar Pradesh, India.

BACKGROUND & OBJECTIVE: Outbreaks of an acute encephalopathy syndrome affecting children, with high case-fatality, have been reported in western Uttar Pradesh, India for the last many years.We investigated these cases in Bijnor district and present our findings. METHODS: Fifty five children aged 2-10 yr hospitalized from 2003 to 2005 in Bijnor, Uttar Pradesh, with features of acute encephalopathy were selected by defined clinical criteria. Various laboratory investigations were performed. RESULTS: The disease had peak incidence in early winter months. Previously healthy, 2-4 yr old rural children (mean age-3.78 yr) of very low socio-economic background were most vulnerable. Almost all had vomiting preceding unconsciousness and a majority had mild fever and abnormal behaviour/agitation. Abnormal posture of trunk and limbs were distinctive features. Fluctuation of blood pressure was seen in three-quarter cases. Serum aminotransferases, creatine phosphokinase and lactic dehydrogenase levels were found markedly raised virtually in all cases in whom the tests were performed. Serum glucose was found low (<50 mg/dl) in 47.3 per cent cases at presentation. Cerebrospinal fluid (CSF) was under normal or low pressure and without pleocytosis in all cases. No microorganism could be isolated from serum, CSF, urine and visceral specimens. Neuroimaging performed in two cases was also normal. Liver biopsy performed in 21 cases showed acute hepatotoxic injury in all with marked hydropic change and perivenular necrosis. Tibial muscle biopsy done in 8 cases showed focal necrosis while brain biopsy taken in 2 cases had mild spongiosis with focal gliosis. Forty two children succumbed to their illness (case fatality 76.4%), most within 72 h of presentation. Survivors did not show any neurological deficit. INTERPRETATION & CONCLUSION: Our findings showed that the outbreaks were due to a multi-system disease with toxic injury to liver, muscles and brain (hepato-myo-encephalopathy) and not due to viral encephalitis as believed so far. The cause remains unknown but several features suggest the possibility of phytotoxin-induced pathology.

[Epidemiologic profile and management pediatric medical emergencies consultants of Tunisian child's hospital]

Background: the pediatric medical emergencie's of Tunisian child's hospital service manages all children fifteen years old. It received 45 000 children in year in average

The aims: establish an epidemiologic profile of consultants and study the encountred morbidity

Methods: we made a transversal describing study of the pediatric emergencie's activity during three successive months in 2004 [February, March, April]. We described the characteristics of the population consulting this service, study the severity and immediate behaviours in emergencies

Results: The number of all consultants is 10560 children during these three months. 54.9% of cases are between one month old and two years old, 54.7% of them are boys

The recruitment mode is direct in 92.9% of cases. The maximum of consultants is in the week-ends with an average of 129 patients per day

In the other days of the week, the average number is 115 +/- 27 patients per day ant the extrems are 75 and 225 patients per day. In the morning, a third of the daily activity is made the morbidity is dominated by the pulmonary pathologies in 39.9% of cases, otorhinolarygologic affections in 31.8% of cases, gastroenterologic pathologies in 6.72% of cases and brain system's pathology in 3.43% of cases. The neonatal affection represents 2.74% of total consultants. At the end of the consultations, 38.7% of patients go back home with medical prescriptions. 45.6% of them receive nebulisations and 21.3% are hospitalized. The bulk is the first dysfunction of the emergencies service. The second dysfunction is the inappropriate use of this service which works like a first structure. Some affections such as febrile seizures, pyelonephritis are excessively hospitalized in 97.5% and 100% respectively

Conclusion: The dysfunction of pediatric medical emergencies's service can be improved by sanitary education of the parents about the role of emergencie's service and the formation of the doctors in the management of patients suffering from usual emergencies

Industrial Accident Compensation Insurance Benefits on Cerebrovascular and Heart Disease in Korea

The purpose of this study is to present the importance of work-related cerebrovascular and heart disease from the viewpoint of expenses. Using the insurance benefit paid for the 4,300 cases, this study estimated the burden of insurance benefits spent on work-related cerebrovascular and heart disease. The number of cases with work-related cerebrovascular and heart disease per 100,000 insured workers were 3.36 in 1995; they were increased to 13.16 in 2000. By the days of occurrence, the estimated number of cases were 1,336 in 2001 (95% CI: 1,211-1,460 cases) and 1,769 in 2005 (CI: 1,610-1,931 cases). The estimated average insurance benefits paid per person with work-related cerebrovascular and heart disease was 75-19 million won for medical care benefit and 56 million won for other benefits except medical care. By considering the increase in insurance payment and average pay, the predicted insurance benefits for work-related cerebrovascular and heart disease was 107.9 billion won for the 2001 cohort and 192.4 billion won for the 2005 cohort. From an economic perspective, the results will be used as important evidence for the prevention and management of work-related cerebrovascular and heart disease.

Neuropsychological alterations after coronary artery bypass graft surgery.

OBJECTIVE: To evaluate neuropsychological dysfunction in patients following elective coronary artery bypass graft surgery at Siriraj Hospital. PATIENTS AND METHOD: One hundred and ten patients who were scheduled for elective coronary artery bypass graft surgery were included in this study. We used the Thai Mental State Examination (TMSE) in order to detectthe presence of cognitive impairment aftercoronary artery bypass graft surgery. The examinations were conducted on two consecutive occasions; first preoperatively, the day before surgery, secondly on the third - fifth postoperative day. The patients' clinical characteristics were assessed perioperatively. RESULTS: The overall occurrence of neuropsychological deficit was 18.18 per cent. Predictors of neuropsychological dysfunction were older age and preexisting disease such as hypertension, hypercholesterolemia and renal insufficiency. Other risk factors such as gender, history of congestive heart failure, myocardial infarction, diabetes mellitus, dysrhythmia, cardiopulmonary bypass time, hemoglobin during cardiopulmonary bypass <7 g/dl, hemoglobin on admission to surgical cardiac care unit <10 g/dl, and atrial fibrillation arising after surgery were not significant. CONCLUSION: Neuropsychological impairments after coronary artery bypass graft surgery are relatively common. This study did not find an increased incidence with respect to gender as other studies have done. However, long-term follow-up of these patients would be very valuable.

Complicaciones en niños con varicela en cuatro hospitales de Santiago-Chile: espectro clínico y estimación de costos directos / Varicella complications requiring hospitalization in four hospitals in Santiago, Chile: clinical spectrum and estimation of direct costs

Background: The knowledge of varicella complications and their associated cost may help for a better evaluation of varicella immunization benefits. Aim: To determine frequency, type, outcome and affected population of varicella complications in children requiring hospitalization, and to estimate their direct costs. Material and methods: Retrospective analysis of medical records of children admitted to four hospitals in Santiago, Chile, due to varicella complications between January 1997 and February 1999. Calculation of direct costs of hospitalizations in a sample of 30 patients. Results: One hundred fifty four patients were identified, 74 percent were younger than 5 years old, only one was immunocompromised. Complications identified were skin and soft tissue infections in 63 percent, invasive infections in 25,3 percent, neurological in 7.1 percent and miscellaneous in 4,5 percent. Staphylococcus aureus and Group A ß-haemolytic Streptococcus (GABS) were predominantly isolated. S. aureus was the main agent identified in superficial infections and GABS in invasive infections (sterile sites). Two patients died due to invasive infections (streptococcal toxic shock and S. aureus septicaemia) and 11 required surgical procedures. The average cost per hospitalization was US$ 600 in public hospitals and US$ 1,800 in the private hospital. Conclusions: Varicella complications requiring hospitalization are due mainly to bacterial infections and they affect immunocompetent toddlers. These complications can be severe and even fatal

A criança com encefalopatia: onde fica a família? / The child with encephalopathy: what is the family's role?

No grupo de patologias, que acomete o sistema nervoso ou muscular das crianças, as encefalopatias näo evolutivas representam afeccöes neurológicas seqüelares do período perinatal, que embora estáveis e näo progressivas, permitem às crianças acometidas, aquisiçäo e progresso de seu desenvolvimento psicomotor desde que bem assistidas. No contexto de tratamento das crianças com encefalopatias, as famílias ocupam papel de importância fundamenta, ao lado da equipe de terapêutas. Este estudo teve como objetivo identificar as dificuldades físicas, emocionais e sociais, envolvidas na relaçäo familiar de crianças com encefalopatias, atendidas na Fundaçäo Centro de Reabilitaçäo Dom Aquino Corrêa bem com o tratamento fisioterápico. Optou-se por estudar as famílias de crianças de 0 a 3 anos, pois, nesta fase ocorre a descoberta da doença, trazendo grandes distúrbios emocionais à família. Os resultados mostram que vários fatores säo considerados entraves para a participaçäo efetiva no tratamento como, condiçäo sócio-econômica, grau de escolaridade, altas expectativas, sobrecarga da mäe e descompromisso do pai. Também, a equipe de saúde se aperfeiçoa no atendimento técnico, mas inexiste formas de como melhor realizar uma orientaçäo familiar. Assim, a saúde se aperfeiçoa no atendimento técnico, mas inexiste formasde como melhor realizar uma orientaçäo familiar. Assim, a saúde na encefalopatia vai além do seu tratamento clínico e de reabilitaçäo, abrangnedo a saúde da família e de todos ligados ao universo da criança.

Toxoplasmosis of the central nervous system in the acquired immunodeficiency syndrome.

Acute encephalitis caused by Toxoplasma gondi was diagnosed at autopsy in 10 (20.4%) of the 49 patients. All patients had under lying immunodeficiency due to AIDS and showed selective involvement of central nervous system at autopsy. Sexual promiscuity was the risk factor in nine cases while one case had a history of blood transfusion. Diagnosis of toxoplasmosis was hampered by a lack of suspicion that Toxoplasma could be the agent causing necrotising encephalitis. The large number of cases of CNS toxoplasmosis appearing in AIDs patients emphasize the necessity of including toxoplasmosis in the differential diagnosis of encephalitis of unknown aetiology.

Long term morbidity in survivors of the 1984 Bhopal gas leak.

BACKGROUND: The extent and nature of long term health sequelae among survivors of the Bhopal gas disaster are not known. In 1994 an International Medical Commission was set up with the aim of assessing respiratory, neurological and other health effects attributable to gas exposure. METHODS: An epidemiological survey of a representative sample of gas-exposed inhabitants of Bhopal was conducted in January 1994; for reference, a group of unexposed persons in the same city were surveyed. Questionnaires regarding health and exposure were administered to 474 persons, and a random sample (n=76) were subjected to respiratory and neurological testing. Responses to the questionnaire and the results of clinical testing were analysed according to a measure of individual gas exposure. RESULTS: A large number of subjects reported general health problems (exposed v. unexposed; 94% v. 52%) and episodes of fever (7.5/year v. 2.5/year); adverse outcome of pregnancy (e.g. still-births, 9% v. 4%) and respiratory symptoms (81% v. 38%), with a strong gradient by exposure category. This was not accounted for by differences in smoking, and was consistent with the results of spirometric testing. Neurological and psychiatric symptoms were reported more frequently by subjects in high exposure categories and the results of neurological examination and testing tended to confirm this finding. Ophthalmic symptoms demonstrated a similar pattern. Although a number of other symptoms were reported (with the possible exception of gastrointestinal disease), there was no clear evidence of other organ system damage attributable to gas exposure. CONCLUSION: The gradient of reported symptoms and clinical test results with estimates of exposure among these survivors of the gas leak suggests that a proportion of their current respiratory and neurological disease was due to gas exposure.

Epidemiología intrahospitalaria del Instituto de Ciencias Neurológicas durante 1992 / Inpatient hospital epidemiology at the Institute of Neurological Sciences

Se realiza un trabajo descriptivo, sobre las características demográficas y las causas de hospitalización en el Instituto de Ciencias Neurológicas (ICN) en Lima-Perú durante 1992. De la revision de las estadisticas de la oficina de estadística del ICN, se obtienen 1783 egresos, 48 por ciento mujeres y 52 por ciento varones, el 66 por ciento de los cuales compone la población economicamente activa, con una edad promedio de 38 años. Un tercio de los pacientes procedian del llamado "Cono Norte" de Lima y el resto, de la mayoria de distritos del país. Se observa en el ICN y en el Servicio de Neurologia del Hopspital Nacional Guillermo Almenara Irigoyen (HNGAI), que atiende a la población aegurada, una gran similitud en cuanto a diagnósticos de alta, figuran asi en orden de frecuencia: la enfermedad ("accidente") cerebrovascular, la epilepsia, la cefalea y la neurocisticercosis, en ambos centros. Es notoria la tendencia a una permanencia hospitalaria superior al promedio, con 15 días en el HNGAI y 26 en el ICN respectivamente; comparando a 9 dias del IPSS a nivel nacional y 14 del HNCH. Asi mismo se observa claramente una mayor mortalidad intrahospitalaria de las enfermedades neurológicas, pues estas superan el promedio internacional de 40 por mil para un hospital general y al promedio general del HNCH de 38 por mil, siendo de 48 por mil para el ICN y de 49 por mil para el HNGAI durante el mismo periodo estudiado. Resalta una diferencia importante entre los tipos de enfermedad cerebrovascular observados, asi en el ICN son eventos isquémicos el 81 por ciento, 13 por ciento hemorrágicos, y 6 por ciento hemorragias subaracnoideas; siendo en el HNGAI el 30 por ciento hemorragicos y el 70 por ciento isquémicos, sin considerar las hemorragias subaracnoideas. La explicación de estas diferencias, sea por métodos diagnósticos o por características distintas de la población asegurada y no asegurada, asi como otras características de las enfermedades señaladas por su frecuencia, es motivo de nuevos estudios intrahospitalarios y en población

Computed tomographic evaluation of pineal calcification.

A prospective study to ascertain the incidence of normally calcified pineal gland, was carried out in 1000 consecutive patients from different parts of Uttar Pradesh (India), undergoing cranial computed tomography for reasons other than a pineal or parapineal pathology. A total of 167 (16.70%) patients were found to have calcified pineals. Of these 128 were males and 39 females. The incidence rose from 1.16 per cent in the first decade to 31.88 per cent above the age of 50 yr. The percentage incidence of normal pineal calcification was lower than that seen in the Western population. No significant difference was found between men and women in any age group. Although calcification appeared as early as the first decade, this percentage was significantly lower than in the higher age groups. Significantly higher incidence rates were seen in the second decade, third decade and sixth decade onwards.

Cerebral malaria--an analysis of 55 cases.

This study reflects the clinical pattern, diagnosis and management of cerebral malaria in 55 consecutive patients from Chittagong Hill Tracts. The predominant clinical features were: impaired consciousness with convulsion in a febrile patient with temporary residence in the endemic zone. Younger people were more prone to develop this condition. Thirty two patients (58.18%) were between 18-25 years. A high incidence of cerebral malaria was noted in blood group 'O' (37.5%) and group 'B' (33.33%). The malarial parasite count MPC was not proportional to the severity of the disease. Twenty four patients (43.63%) had malarial parasite count below 100% cumm. Anaemia (63.63%) and Jaundice (34.54%) were common, Splenomegaly (7.27%) was uncommon. Clinical features of cerebral oedema/raised intracranial pressure were not evident. CSF study was unremarkable except for raised pressure in 7 patients (12.65%). Response to intravenous quinine was satisfactory and yet the mortality was 11%.
