Uso de ibuprofeno en el tratamiento de pacientes pediátricos con poliuria y disnatremia. Reporte de una serie de casos / Ibuprofen use for the treatment of pediatric patients with polyuria and dysnatremia. A case series report

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.

Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Sarcopenia and consumptive syndrome in HIV-infected patients receiving antiretroviral therapy in a public hospital in Northeast Brazil / Sarcopenia y síndrome de emaciación en pacientes infectados por el HIV que reciben terapia antiretroviral en un hospital público en el noreste Brasil

We evaluated the prevalence of sarcopenia and wasting syndrome, as well as the associated factors in HIV-infected patients receiving antiretroviral therapy. We utilized a cross-sectional study evaluating HIV-infected individuals at a university hospital in the Northeast area of Brazil. In 99 patients, sarcopenia was assessed by analysis of muscle mass, muscle strength and physical performance. Wasting syndrome was assessed by unintentional weight loss criteria. Demographic, socioeconomic, anthropometric, as well as clinical and lifestyle variables were also evaluated. The prevalence of sarcopenia in this sample was 18.2% and 33.3% presented severe sarcopenia. Wasting syndrome was identified in 13.1% and 4% presented both conditions. Sarcopenia had higher prevalence in older patients (80.0 vs 4.9%, p= 0.004), among those with diabetes mellitus (50.0 vs 16.1%, p= 0.037), as well as among malnourished individuals (p= 0.003). Wasting syndrome was more prevalent in individuals with a lower level of education (26.3%vs5.4%, p= 0.005), in the lower income tertile (p= 0.041), and a lower CD4+ T cell count (429±450 vs 654±321 cells/mm3, p= 0.045). Sarcopenia and wasting syndrome are still clinical problems present in those using antiretroviral therapy associated with specific conditions in HIV patients.

Se evaluó la prevalencia de la sarcopenia, síndrome de emanciación y factores asociados en pacientes infectados por HIV que recibieron terapia antirretroviral. En la evaluación de las personas infectadas por el HIV se aplicó un diseño de tipo transversal y fue realizado en un hospital universitario en la zona noreste del Brasil. La sarcopenia se evaluó mediante la medición de la masa muscular, la fuerza muscular y el rendimiento físico. El síndrome de emanciación se evaluó mediante criterios de pérdida de peso involuntarios. También se evaluaron las características demográficas, socioeconómicas, antropométricas, así como las variables clínicas y de estilo de vida. La prevalencia de sarcopenia en esta muestra de pacientes fue del 18,2%, y de esta población un tercio presentó sarcopenia grave. El síndrome de emanciación se identificó en el 13,1% de los pacientes y en el 4% de los sujetos que presentaron ambas condiciones. La sarcopenia tenía mayor prevalencia en pacientes de mayor edad (80,0 vs 4,9%, p= 0,004), en las personas con diabetes mellitus (50,0 vs 16,1%, p= 0,037), así como en sujetos desnutridos (p= 0,003). El síndrome de emanciación fue más prevalente en sujetos con un nivel más bajo de educación (26,3% vs 5,4%, p= 0,005), menor tercil de ingresos (p= 0,041), y menor recuento de células TCD4+ (429±450 vs 654±321 células/mm3, p= 0,045). Sarcopenia y síndrome de emanciación son todavía problemas clínicos presentes en aquellos que utilizan la terapia antirretroviral asociada con condiciones específicas en pacientes con HIV.

Wasting Syndrome (WS) was found in 139 patients whose basic illness did not explain it 76. Conclusions: The quality and quantity of the food intake is inadequate and there is a high percentage of SDO in patients without a medical justification for this(AU)

A Case of Cerebral Salt Wasting Syndrome in Neuromyelitis Optica Spectrum Disorder

Neuromyelitis optica spectrum disorder (NMOSD) may present with area postrema syndrome, which is characterized by intractable vomiting and hiccups. Hyponatremia is common in NMOSD and is mostly associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In contrast to SIADH, cerebral salt wasting syndrome (CSWS) causes hyponatremia, which is associated with severe natriuresis and extracellular volume depletion in patients with cerebral disease. To our knowledge, hyponatremia associated with CSWS has not been reported in a patient with NMOSD. Here, we describe a NMOSD presenting with hyponatremia, which may be caused by CSWS following area postrema syndrome.

Perfil clínico-nutricional de portadores do vírus HIV atendidos em um hospital de referência do Nordeste brasileiro / Clinical-nutritional profile of HIV patients in a referral hospital in the northeast of Brazil

A AIDS caracteriza-se como doença degenerativa, crônica e progressiva. Após a introdução da terapia antirretroviral (TARV), observou-se uma importante redução na morbimortalidade. No entanto, ao longo do tratamento, os indivíduos podem apresentar alterações cardiometabólicas. Objetivo: Avaliar o perfil clínico-nutricional de portadores de HIV atendidos em um hospital de referência do Nordeste brasileiro. Métodos: Estudo do tipo descritivo transversal realizado no ambulatório e na unidade de internação de Doenças Infecto-Parasitárias (DIP) do Hospital das Clínicas da Universidade Federal de Pernambuco. Foram avaliadas variáveis nutricionais e clínicas. A amostra foi não probabilística por conveniência. Os dados foram digitados no programa Excel para Windows® e as análises realizadas no Programa SPSS® versão 13.0, com nível de significância de 5% para rejeição de hipótese de nulidade. Resultados: Foram avaliados 110 pacientes (54,5% em enfermaria). A média de idade foi 39±11 anos, e 15,4% possuíam 50 anos ou mais. Do total, 64,5% eram do sexo masculino. Entre os pacientes de enfermaria, 52,5% apresentaram complicações metabólicas; 1,6%, lipodistrofia e 15%, síndrome consumptiva, enquanto os pacientes ambulatoriais apresentaram valores de 76%, 4% e 4%, respectivamente. Tempo de diagnóstico, indicação, tempo e adesão à TARV não mostraram diferenças entre os grupos. Conclusão: As alterações metabólicas relacionadas a risco cardiovascular e à preservação do estado nutricional prevaleceram nos pacientes ambulatoriais, enquanto o perfil clínico-nutricional dos internados mostrou a desnutrição energético-proteica como a complicação mais frequente, com maior comprometimento do sistema imunológico e maior frequência de infecções oportunistas e sintomas gastrointestinais. O uso de drogas lícitas e/ou ilícitas, a falta de conhecimento sobre a importância da medicação e a negligência no autocuidado foram os principais motivos para o uso irregular da TARV

The acquired immunodeficiency syndrome is a chronic, progressive, and degenerative disease. Since the introduction of antiretroviral therapy (ART), a significant reduction in mortality and morbidity rates has been recorded. However, patients may present cardiometabolic changes throughout the treatment. Objective: To assess the clinical and nutritional profile of HIV patients treated in a referral hospital in northeast Brazil. Methods: Descriptive cross-sectional study performed in inpatient and outpatient units for infectious and parasitic diseases at the Hospital of the Universidade Federal de Pernambuco Nutritional and clinical variables were assessed. The sample was a non-probabilistic convenience sample. The data were entered into Excel for Windows® and analyzed using SPSS® software (version 13.0), with a 5% level of significance set for the rejection of the null hypothesis. Results: In total, 110 patients were assessed (54.5% in infirmary). The mean age was 39±11 years, with15.4% of the individuals aged 50 years or more. Of the total, 64.5% were male. Among the patients in the ward, 52.5% had metabolic complications; 1.6% had lipodystrophy, and 15% had wasting syndrome, while ambulatory patients showed values of 76%, 4%, and 4%, respectively. Time of diagnosis, indication, time, and adherence to ART showed no differences between the groups. Conclusion: The metabolic changes related to cardiovascular risk factors and the preservation of nutritional status prevailed in ambulatory patients, while the clinical-nutritional profile of hospitalized patients showed energy-protein malnutrition as the most common complication, with greater involvement of the immune system and increased frequency of opportunistic infections and gastrointestinal symptoms. The use of licit and/or illicit drugs, the lack of knowledge about the importance of medication, and the negligence in care were the main reasons for the irregular use of ART.

The application of adrenal cortical hormone in the treatment of cerebral salt wasting syndrome / 中国医师进修杂志

Cerebral salt wasting syndrome (CSWS) is a common cause of refractory hyponatremia. Early diagnosis and treatment of CSWS can greatly improve the patient′s condition and improve the prognosis. Clinically by supplying sodium hydrate, most patients can resume normal serum sodium level, and get remission. But a few patients with low serum sodium, high urine sodium and low blood volume can not improve and even worse. Fludrocortisone and adrenal cortical hormone can rapidly and effectively reduce the urinary sodium level and urine volume, correct hyponatremia and low blood volume and improve the prognosis in such patients.

Underweight prevalence among young adults from rural areas, Salin Towinship, Magwe Region.

Maintaining a normal body mass index (BMI) throughout the life-span of a person may reduce occurrence as well as the burden of non-communicable diseases (NCDs), in terms of years lived with disability and premature death. Lifestyle and socioeconomic factors like physical activity and availability of healthy or unhealthy food may contribute to both extremes of BMI, namely underweight and overweight/obesity. The aim of the present cross-sectional study was to estimate the prevalence of underweight and overweight/obesity and selected lifestyle factors in a cluster randomized sample of 335 young adults aged 18-35 years from rural communities residing at SalinTownship, Magwe Region. In addition, it also aims to investigate the association between selected socioeconomic and lifestyle factors with underweight. Data were collected by carrying out face to face interviews with the individuals selected in the sample in 2011 using semi-structured questionnaires and measuring of their weight and height. SPSS version 16 and STATA version 11 were used for data entry and analysis respectively. Based on WHO criteria, participants were classified according to their BMI into underweight (BMI < 18.5); normal weight (BMI 18.5 - 24.99); and overweight/obese (BMI > 25). Individuals with normal BMI was found in 72% (95% confi dence interval (CI): 67.1 - 77.0) and the prevalence of underweight was found in 28% (23.0 - 32.9). The majorities of respondents were illiterates, of monastic and primary schooling, and working as farmers and manual workers. Nearly 84% of the respondents were able to have 3 meals per day, and the same proportion consumed vegetables daily. The prevalence of current smokers was 11% and all were found to be males. Seventy-two percent were physically active on a daily basis. Out of these respondents, three-fourths of them were physically active at least two hours per day. A total of 64% reported to sleep during the day and 71% reported less than 8 hours of sleeping during the night. Logistical regression analysis showed that underweight was significantly associated with lower age as compared to higher age (OR = 0.54: CI 0.32 - 0.92). There was no significant association between sex, education, occupation and lifestyle factors.

Bases fisiopatológicas de los transtornos del sodio en pediatría / Pathophysiology of sodium disorders in children

Las disnatremias son el transtorno hidroelectrolítico prevalente en pacientes ambulatorios y hospitalizados. Su manejo inadecuado puede tener serias consecuencias, asociándose a un aumento en la morbimortalidad de los pacientes. El objetivo de este artículo es actualizar las bases fisiopatológicas de las disnatremias y revisar herramientas clínicas y de laboratorio que nos permitan realizar un enfrentamiento rápido y simple. Las disnatremias reflejan un transtorno del balance del agua, y el balance de agua tiene relación directa con la osmorregulación. Existen mecanismos para mantener el control de la osmolalidad plasmática, los cuales se gatillan con cambios de un 1-2 por ciento. A nivel hipotalámico existen osmorreceptores que censan cambios en la osmolalidad plasmática, regulando la secreción de Hormona Antidiurética (ADH), la que ejerce su acción a nivel renal, por lo cual el riñón es el principal regulador del balance hídrico. Cuando se está frente a una disnatremia, es fundamental evaluar cómo está funcionando este eje ADH-riñón. Dentro de las hiponatremias existen causas que son fáciles de identificar, sin embargo, diferenciar un síndrome de secreción inadecuada de ADH con un síndrome pierde sal cerebral suele ser más difícil. En el caso de las hipernatremias, sospechar una diabetes insípida y diferenciar su posible origen, central o nefrogénico, es fundamental para su manejo. En conclusión, el enfrentamiento de una disnatremia requiere conocer las bases fisiopatológicas de su desarrollo, para así poder realizar un diagnóstico certero y finalmente un tratamiento adecuado, evitando errores en su corrección que pueden poner en riesgo al paciente.

Dysnatremia is among the most common electrolyte disorders in clinical medicine and its improper management can have serious consequences associated with increased morbidity and mortality of patients. The aim of this study is to update the pathophysiology of dysnatremia and review some simple clinical and laboratory tools, easy to interpret, that allow us to make a quick and simple approach. Dysnatremia involves water balance disorders. Water balance is directly related to osmoregulation. There are mechanisms to maintain plasma osmolality control; which are triggered by 1-2 percent changes. Hypothalamic osmoreceptors detect changes in plasma osmolality, regulating the secretion of Antidiuretic Hormone (ADH), which travels to the kidneys resulting in more water being reabsorbed into the blood; therefore, the kidney is the main regulator of water balance. When a patient is suffering dysnatremia, it is important to assess how his ADH-renal axis is working. There are causes of this condition easy to identify, however, to differentiate a syndrome of inappropriate ADH secretion from cerebral salt-wasting syndrome is often more difficult. In the case of hypernatremia, to suspect insipidus diabetes and to differentiate its either central or nephrogenic origin is essential for its management. In conclusion, dysnatremia management requires pathophysiologic knowledge of its development in order to make an accurate diagnosis and appropriate treatment, avoiding errors that may endanger the health of our patients.

Differentiation of the cerebral salt wasting syndrome and syndrome of inappropriate antidiuretic hormone secretion / 国际儿科学杂志

The cerebral salt wasting syndrome and syndrome of inappropriate antidiuretic hormone secretion are frequent in hyponatremia in patients with intracranial disorders.There is a major problem about the incidence,diagnosis,and differentiation of cerebral salt wasting syndrome and syndrome of inappropriate secretion of antidiuretic hormone in patients with acute central nervous system disorders.Clinical presentation of cerebral salt wasting syndrome is similar to syndrome of inappropriate antidiuretic hormone secretion,but the therapy is different.So differential diagnosis is essential for appropriate management.This paper differentiate two kinds of diseases from the pathogenesis,diagnosis and treatment.

Linfadenopatia e lúpus eritematoso sistêmico / Lymphadenopathy and systemic lupus erythematosus

A linfadenopatia no lúpus eritematoso sistêmico (LES) é um achado benigno encontrado comumente em jovens, com atividade cutânea e sintomas constitucionais, apresentando boa resposta à corticoterapia. O achado mais frequente à biópsia é a hiperplasia folicular reacional. Relatamos o caso de um paciente que, desde os 13 anos de idade, apresentava surtos recorrentes de linfadenopatia, acompanhados de hepatoesplenomegalia, febre e emagrecimento. Na evolução, apareceram artrite, hipertensão arterial, proteinúria, miocardiopatia e neuropatia periférica. Foi amplamente investigado sem esclarecimento diagnóstico e submetido a tratamento empírico de tuberculose. Somente após cinco anos de evolução firmou-se o diagnóstico de LES e recebeu tratamento específico. O diagnóstico precoce nestes casos é difícil, pois a investigação laboratorial pode ainda não demonstrar presença de autoanticorpos ou hipocomplementemia.

Lymphadenopathy is a benign finding in systemic lupus erythematosus (SLE), commonly seen in young patients with cutaneous involvement and constitutional symptoms, with good response to corticosteroids. Reactive follicular hyperplasia is the most frequent finding in biopsies. We report the case of a patient with recurrent episodes of lymphadenopathy associated with hepatosplenomegaly, fever, and weight loss since the age of 13 years. The patient also developed arthritis, hypertension, proteinuria, cardiomyopathy, and peripheral neuropathy. His condition was investigated extensively without diagnostic clarification; he was treated, empirically, for tuberculosis. The patient received a diagnosis of SLE only five years after the original presentation and received the specific treatment. Early diagnosis in those cases is difficult because laboratorial exams may not show the presence of auto-antibodies and low complement levels.

Hyponatremia in Patients with Neurologic Disorders

The kidney and the brain play a major role in maintaining normal homeostasis of the extracellular fluid by neuroendocrine regulation of sodium and water balance. Therefore, disturbances of sodium balance are common in patients with central nervous system (CNS) disorders and clinicians should focus not only on the CNS lesion, but also on the potentially deleterious complications. Hyponatremia is the most common and important electrolyte disorder affecting patients with critical neurologic diseases. In these patients, the maladaptation to hyponatremia by impaired osmoregulation in pathologic lesions of brain may cause more aggressive cerebral edema and increased intracranial pressure due to hypoosmolality induced by hyponatremia. Furthermore, hyponatremia accompanied by CNS disorders has shown to increase delayed cerebral ischemia and mortality rates. Two main pathophysiologies of hyponatremia, excluding iatrogenic causes, are inappropriate secretion of antidiuretic hormone (SIADH) and cerebral salt wasting (CSW) syndrome. Differential diagnosis between these two entities can be difficult due to considerable overlap in the laboratory findings and clinical situations. SIADH is in a volume expanded status due to inappropriately secreted arginine vasopressin (AVP) and requires water restriction. However, CSW syndrome is characterized by renal sodium wasting mainly due to increased natriuretic peptides resulting in volume depletion and follows appropriate secretion of AVP. Therefore, maintenance of volume status and sodium replacement is the mainstay of treatment in CSW syndrome. In this review, we aimed to describe the regulation of sodium and water balance, and pathophysiology, diagnosis and treatment of hyponatremia in neurologic patients, especially focusing on SIADH and CSW syndrome.

O papel do hormônio de crescimento no tratamento dos distúrbios endócrino-metabólicos do paciente com a síndrome da imunodeficiência adquirida (Aids): [revisão] / The use of growth hormone to treat endocrine-metabolic disturbances in acquired immunodeficiency syndrome (Aids) patients: [review]

As primeiras descrições da síndrome da imunodeficiência adquirida (Aids) associavam-se à síndrome de emaciamento, e os distúrbios metabólicos às alterações na composição corporal. Após a introdução da terapia anti-retroviral altamente ativa (HAART), houve declínio na desnutrição, e surge a lipodistrofia como importante distúrbio metabólico. A Aids também se caracteriza por distúrbios hormonais, principalmente no eixo hormônio de crescimento/fator de crescimento insulina-like tipo 1 (GH/IGF-1). O uso do GH recombinante humano (hrGH) foi inicialmente indicado na síndrome de emaciamento, a fim de aumentar a massa muscular. Embora também não existam dúvidas quanto aos efeitos do hrGH na lipodistrofia, a diminuição na sensibilidade à insulina limita o seu uso, o qual ainda não está oficialmente aprovado. A diversidade nos esquemas de tratamento é outro limitante do uso dessa medicação em pacientes com Aids. Esta revisão apresenta os principais distúrbios endócrino-metabólicos associados à Aids e ao uso do hrGH nessas condições.

Acquired Immunodeficiency Syndrome (Aids) was initially related to HIV-associated wasting syndrome, and its metabolic disturbances to altered body composition. After Highly Active Antiretroviral Therapy (HAART) was started, malnutrition has declined and HIV-associated lipodystrophy syndrome has emerged as an important metabolic disorder. Aids is also characterized by hormonal disturbances, principally in growth hormone/insulin-like growth factor 1 (GH/IGF-1) axis. The use of recombinant human GH (hrGH) was formerly indicated to treat wasting syndrome, in order to increase lean body mass. Even though the use of hrGH in lipodystrophy syndrome has been considered, the decrease in insulin sensitivity is a limitation for its use, which has not been officially approved yet. Diversity in therapeutic regimen is another limitation to its use in Aids patients. The present study has reviewed the main HIV-related endocrine-metabolic disorders as well as the use of hrGH in such conditions.

Diagnosis and therapy of severe cerebral injured patients with hyponatremia / 中国基层医药

Objective To study the clinical features and therapeutic method of severe cerebral injured patients with hyponatremia.Methods The electrolyte and central venous pressure were examined on 45 cases of severe cerebral injured patients with hyponatremia every day.According to plasma sodium value and central venous pressure,we regulated treatment perscription daily.Results 45 patients occured hyponatremia in total 288 of severe cerebral injured patients.Hyponatremia was detected 5～13 days after operation or after injure.The morbility is usually the highest in the seventh day.Plasma sodium recovered to normal value in 14 days after operation.Conclusion Severe cerebral injured patients with hyponatremia should be diagnosed and treated as early as possible,then it will receive better prognosis.

Evaluating and Managing Hyponatremia / 대한구급학회지

Although hyponatremia is a common electrolyte disorder, its evaluation and management are not well defined. When diagnosed, hyponatremia should be categorized based on four criteria: volume status, urinary Na+, serum K+, and acid-base balance. This approach helps to determine what the cause of hyponatremia is and how it should be treated. Initially, hypovolemic hyponatremia, including cerebral salt wasting syndrome (CSWS), is treated by volume resuscitation and salt supplementation. Euvolemic hyponatremia, including the syndrome of inappropriate secretion of antidiuretic hormone (SIADH), is treated by fluid restriction and salt supplementation, and hypervolemic hyponatremia is treated by fluid restriction and salt restriction. Hyponatremia can be managed well using these primary treatments and medications.

Uso do plasma suíno ultrafiltrado na recuperação de leitões com sinais clínicos de circovirose / The use of ultra-filtered swine plasma in the recovery of pigs with clinical signs of porcine circovirus infection

Testou-se o efeito do plasma suíno ultrafiltrado spray-dried, associado a um acidificante comercial na água de bebida para a recuperação de leitões com sinais clínicos da síndrome multissistêmica do definhamento dos suínos (SMDS). Utilizaram-se 40 leitões com sinais clínicos da SMDS, selecionados 20 dias após o alojamento em uma unidade de terminação, distribuídos em quatro tratamentos (T) de 10 leitões cada. No T1, os animais receberam água clorada à vontade (controle); no T2, solução com 2,5 por cento do plasma sangüíneo diluído em água; no T3, acidificante (Selko®) diluído em água na dosagem de 12ml/10l e, no T4, solução com 2,5 por cento do plasma sangüíneo e o acidificante na dose de 12ml/10l, diluídos em água. Os leitões não foram medicados e foram sacrificados aos 28 ou 40 dias de experimento para avaliação sorológica e patológica. Não houve diferença no ganho de peso e na situação clínica-patológica entre os tratamentos. Entretanto, os leitões do T4 estavam em melhor situação clínica-patológica. Os leitões dos quatro tratamentos tiveram boa recuperação, sem terem sido medicados. Observou-se alta freqüência de lesões compatíveis com a SMDS nos pulmões, rins e linfonodos. Concluiu-se que o plasma spray dried associado ao ácido não melhoraram o desempenho e a situação clínica-patológica de leitões com sintomas da SMDS

The effect of the ultra-filtered spray-dried porcine plasma, associated to a commercial acid in the drinking water was tested for recovering pigs with clinical signs of the porcine postweaning multisystemic wasting syndrome (PMWS). Forty piglets with clinical signs of the PMWS were used following a selection at 20 days after their housing in one finishing facility. They were divided in four treatment groups (T) of 10 pigs each: T1 - chlorine treated water ad libitum (control); T2 - solution prepared with 2.5 percent of plasma diluted in water; T3 - acid (Selko® ) diluted in water at the concentration of 12 ml/10l; T4 - solution prepared with 2.5 percent of plasma diluted and the acid (Selko® ) diluted in water at the concentration of 12 ml/10l. The pigs received no medication and were euthanized at 28 or 40 days after the beginning of the experiment for serological and pathological tests. Differences at the weight gain and in the clinical-pathological situation were not observed among the treatments. However, pigs from T4 were in better clinical-pathological situation. The pigs of all four treatments showed a good recovery, although they were not medicated. Even though, it was observed a high frequency of lesions compatible to PMWS in the lungs, kidneys and lymph nodes. It was concluded that the plasma spray-dried associated to the acid did not improve the performance and the clinical-pathological situation of pigs with clinical signs of PMWS

Syndromes related to sodium and arginine vasopressin alterations in post-operative neurosurgery

BACKGROUND: Cerebral salt wasting syndrome (CSWS), syndrome of inappropriate antidiuretic hormone secretion (SIADH) and diabetes insipidus (DI) are frequently found in postoperative neurosurgery. PURPOSE: To identify these syndromes following neurosurgery. METHOD: The study included 30 patients who had been submitted to tumor resection and cerebral aneurysm clipping. Sodium levels in serum and urine and urine volume were measured daily up to the 5th day following surgery. Plasma arginine vasopressin (AVP) was measured on the first, third and fifth days post-surgery. RESULTS: CSWS was found in 27/30 patients (90 percent), in 14 (46.7 percent) of whom it was associated with a reduction in the levels of plasma AVP (mix syndrome). SIADH was found in 3/30 patients (10 percent). There was no difference between the two groups of patients. CONCLUSION: CSWS was the most common syndrome found, and in half the cases it was associated with DI. SIADH was the least frequent syndrome found.

INTRODUÇÃO: A síndrome perdedora de sal (SPS), síndrome da secreção inapropriada do hormônio antidiurético (SIADH) e diabetes insipidus (DI) são freqüentemente encontradas no pós-operatório de neurocirurgia. OBJETIVO: Identificar essas síndromes relacionadas à neurocirurgia. MÉTODO: Foram estudados 30 pacientes submetidos à ressecção de tumor (n=19) e clipagem de aneurisma (n=11) cerebral durante os primeiros cinco dias do pós-operatório. Os pacientes foram submetidos a dosagens diárias de sódio sérico e urinário até o 5° dia pós-operatório, com controle de volume urinário neste período e dosagem de arginina-vasopressina (AVP) plasmática no 1°, 3° e 5° dias pós-operatórios. RESULTADOS: A SPS foi encontrada em 27/30 pacientes (90 por cento), em 14/27 (46,7 por cento) associada à diminuição dos níveis de AVP plasmática (síndrome mista). A SIADH foi encontrada em 3/30 pacientes (10 por cento). Não houve diferença entre os dois grupos de pacientes. CONCLUSÃO: A SPS foi a síndrome mais freqüente, em metade de casos associada ao DI. A SIADH foi a menos freqüente.

Systemic and myelotoxic effects of single administration of 2,3,7,8-tetrabromodibenzo-p-dioxin in rats

TBDD-dosed surviving rats exhibited growth retardation, decreased bone marrow hematopoiesis, decreases in red blood cell counts, hemoglobin concentrations, and hematocrit values, an increase in reticulocytes and decreases in platelet counts, white blood cell counts and eosinophils.

Marked decreases in body weights and the size and weight of the thymus, severe thymic atrophy and death in TBDD-dosed females suggested a wasting syndrome.

The adipose tissue level of TBDD culminated on Day 7 and decreased to 20–30% of the Day 7 level on Day 36. Conclusions: The TBDD-induced effects were characterized by a wasting syndrome and myelotoxicity that appeared at the dose levels of 30 μg/kg and higher and caused death in 300 μg/kg-dosed females.
