Comorbid anxiety and depression disorders in patients with chronic pain
Castro, Martha;Kraychete, Durval;Daltro, Carla;Lopes, Josiane;Menezes, Rafael;Oliveira, Irismar;
Arquivos de Neuro-Psiquiatria , 2009, DOI: 10.1590/S0004-282X2009000600004
Abstract: objective: to evaluate the frequency of anxiety and depression disorders in patients with chronic pain. method: patients receiving care at the pain clinic of the federal university of bahia between february 2003 and november 2006. the mini plus - mini international neuropsychiatric interview was used to evaluate the patients and establish psychiatric diagnoses. results: 400 patients were evaluated mean age was 45.6±11.37 years; 82.8% were female, 17.3% male; 48.5% were married; 55.1% were catholics; and 40.5% had only high school education. of these 29.9% reported intense pain and 70.8% reported suffering pain daily. the most frequent medical diagnosis was herniated disc (24.5%), and 48.5% of patients had been undergoing treatment at the pain clinic for less than 3 months. comorbidities found were depressive episodes (42%), dysthymia (54%), social phobia (36.5%), agoraphobia (8.5%) and panic disorder (7.3%). conclusion: psychiatric comorbidities are prevalent in patients suffering chronic pain.

Abstract: A matéria organica foi estudada em latossolo roxo eutrófico, sob vegeta o de cerrado, em Santa Helena (GO), Brasil, em regi o tradicional em plantio direto, em locais onde estavam sendo realizados quatro sistemas de manejo durante dois anos: plantio direto (PD), ara o profunda (AP), grade aradora (GA) e escarifica o profunda (EP). As ervas daninhas observadas na área produziram 2.369, 124, 243, 640 kg/ha de matéria seca no PD, AP, GA e EP, respectivamente, colhidos 30 dias após o preparo do solo. A matéria organica concentrou-se na camada arável do solo onde se realizou o plantio direto (PD) e dispersou nas camadas mais profundas onde se utilizou a ara o profunda (AP). A escarifica o profunda (EP) comportou-se semelhantemente ao plantio direto (PD). Os valores de pH mais baixos foram verificados na camada arável do solo sob manejo do plantio direto. Maior número de fungos e bactérias foi observado nas áreas de plantio direto (PD), bem como de propágulos de Rhizoctonia solani e Fuzariun solani. PALAVRAS-CHAVE: Matéria organica; pH; patógenos do solo; plantio direto; ara o profunda; escarifica o; gradagem; aivecagem. Organic matter was studied in a savanna oxisol during two years, in Santa Helena, state of Goiás, Brazil, a traditional no-till management area, in which four soil management systems were developed: no-tillage (PD), deep moldboard plowing (AP), shallow harrow plowing (GA) and deep stirring, using a chiseling plower (EP). The dry matter from weed plants observed in the area produced 2369, 124, 243, 640 kg/ha in PD, AP, GA and EP, about 30 days after soil management, respectively. The organic matter was concentrated in the arable soil layer in areas where no-till management was adopted (PD) and was dispersed in larger depth in areas where deep plowing (AP) was used. Deep stirring (EP) behaved similarly to the no-till management (PD). Lower pH values were verified at arable surface under the no-till management. Larger number of fungi and bacteria, as well as of propagules of Rhizoctonia solani and Fusarium solani, were also observed in the no-tillage areas (PD). KEY-WORDS: Organic matter; soil pathogenic agents; no-till management.
State-space approach for the analysis of soil water content and temperature in a sugarcane crop
Dourado-Neto Durval,Timm Luís Carlos,Oliveira Julio Cesar Martins de,Reichardt Klaus
Scientia Agricola , 1999,
Abstract: The state-space approach is used to describe surface soil water content and temperature behaviour, in a field experiment in which sugarcane is submitted to different management practices. The treatments consisted of harvest trash mulching, bare soil, and burned trash, all three in a ratoon crop, after first cane harvest. One transect of 84 points was sampled, meter by meter, covering all treatments and borders. The state-space approach is described in detail and the results show that soil water contents measured along the transect could successfully be estimated from water content and temperature observations made at the first neighbour.
Monitoring compliance to an experimental treatment in an asymptomatic population

Einstein (S?o Paulo) , 2008,
Abstract: Objective: To develop strategies and to monitor patient’s adherence to the follow up of the experimental treatment of secondary cholestasis in its isolate chronic form with portal hypertension. Methods: Experimental study made with 11 patients. Ursodeoxycholic acid was administered in the dosage of 15 mg/kg/day twice a day for 45 days. Evaluation of adherence was performed using pill count strategy and interviews. Rresults: The variation during pill count had no influence on the patient’s laboratory results. Serum activity of γGT normalized during treatment, returning to increased levels after interruption of medication. Cconclusions: The strategies developed were effective presenting a significant laboratory result regarding the decrease of γGT serum activity.
Diagnóstico Laboratorial da Puberdade Precoce

Abstract: to evaluate a child with precocious puberty (pp) implies to have a good history and physical exam, which, in itself, can lead to important clues for the etiological diagnosis. it is very important to characterize whether the pp is central (true pp) or peripheral (pseudo-pp) in origin, which have etiologic and therapeutic implications. a well-based lab workup can give the etiological diagnosis with good precision. however, especially in females, the idiopathic forms still account for the majority of cases. in males, a careful search for neoplastic causes is mandatory, since it comprises more than 50% of cases. this paper discusses conceptual and etiologic aspects of pp and gives details for a comprehensive laboratory evaluation.
Uso de horm?nio de crescimento na síndrome de Prader-Willi
Damiani, Durval;
Arquivos Brasileiros de Endocrinologia & Metabologia , 2008, DOI: 10.1590/S0004-27302008000500015
Abstract: prader-willi syndrome (pws), with a prevalence of 60:1.000.000, results from the loss of paternal chromosome 15, being 56% due to deletion, 24% due to uniparental maternal disomy, and 18% from methylation, an epigenetic phenomenon. the clinical picture begins with extreme muscular hypotonia, which makes it difficult to feed the child in the first year. as the hypotonia improves, usually in the first two years, around the 4th year of life, an insatiable appetite leads these children to an extreme obesity, with alveolar hypoventilation which endangers their lives. so, paradoxically, pws threatens the lives of the patients, through inanition in a first phase and, afterwards, through excessive weight gain. the use of growth hormone (hrgh) in these children has a primary goal to change the body composition and improve the physical activity and the quality of life. on the other hand, many pws patients are indeed gh deficient, and an improvement in the height sds occurs with treatment. we have to be careful, however. when starting a pws treatment with a patient on hrgh, a careful evaluation of sleep apnoea (polysomnography) as well as a careful examination of the airways is extremely mandatory, since the treatment may compromise the respiratory pattern of some patients.
