Paracoccidioidomicose pulmonar agressiva, endotraqueíte estenosante e cor-pulmonale subagudo: descrição de um caso

A paracoccidioidomicose (Pbmicose) atinge os pulmões pela via inalatória, onde se estabelece o complexo primário semelhante ao da tuberculose. A traquéia comprometida pela via tubohemolinfática desenvolveria reação inflamatória em processo granulomatoso levando à obstrução estenosante com asíixia. Acompanhou-se um doente, masculino, 32 anos, branco, natural de Sarutaiá (SP), lavrador, que há 8 meses desenvolveu tosse expectorativa branco-amarelada, diária, sem fatores de melhora ou piora e dispnéia inicial discreta. Há 4 meses, anorexia, fraqueza e astenia. Há 1 mês a dispneia se agravou. Perdeu 15 kg. Tabagista e etilista há 16 anos. Exame físico revelou: PA 10/7 mmHg, FR = 28 bpm, peso 31 kg, hipocratismo digital e hipotrofia muscular Tórax enfisematoso e síndrome obstrutivo aos testes de função pulmonar. Coração: P2 desdobrada e hiperfonética. Hepatesplenomegalia. Desenvolveu cor-pulmonale e insuficiência adrenal à internação, evoluindo após 45 dias para óbito em insuficiência respiratória aguda asfixiante, apesar da terapia antifúngica ter sido completa. A literatura médica revista não mostrou registro de caso semelhante de cor-pulmonale e insuficiência adrenal de evolução subaguda.

Função pulmonar na evolução de 35 doentes com paracoccidioidomicose

Lesões pulmonares observadas na paracoccidioidomicose (pbmicose) pela radiologia foram designadas: leve, moderada e grave de acordo com critério estabelecido pelos autores. Lesões infiltrativas intersticiais bilaterais nddulo fibrolineares e cotonosas foram identificadas respectivamente em 34 e em 23 doentes. Formas leve, moderada e grave assinaladas respectivamente em 6 10 e 19 mostraram à análise radiológica evolutiva melhora em 2, piora em 15 e manutenção do padrão da lesão em 18 doentes. Testes de função pulmonar realizados nos doentes durante o retorno ambulatorial evidenciaram: 12 com padrão espirográfico normal, 20 obstrutivos e 3 mistos; 34 doentes estavam hiperventilando e todos apresentaram aumento da diferença alvéolo arterial. Os resultados obtidos permitiram supor que a fibrose residual descrita nos padrões radiológicos; manutenção e piora de 33 deles aliada à doença obstrutiva crônica verificada pelas provas de função pulmonar constituíram subsídios para o desenvolvimento do Cor pulmonale assinalado

Correlações entre os níveis de L-carnitina plasmática, o estado nutricional e a função ventilatória de portadores de doença pulmonar obstrutiva crônica

OBJETIVO: Avaliar os níveis de L-carnitina livre no plasma, o estado nutricional, a função pulmonar e a tolerância ao exercício em pacientes com doença pulmonar obstrutiva crônica e verificar as correlações entre a composição corporal e as frações de L-carnitina no plasma. MÉTODOS: Quarenta pacientes entre 66,2±9 anos, com diagnóstico clínico de doença pulmonar obstrutiva crônica, foram divididos em dois grupos: G1, com índice de massa corporal menor que 20kg/m², e G2, com índice de massa corporal maior que 20kg/m². Foram mensurados os parâmetros espirométricos, a tolerância ao exercício no teste de caminhada, a força muscular respiratória, a composição corporal por meio da impedância bioelétrica e as dosagens da L-carnitina plasmática, através de amostras de sangue. RESULTADOS: Foram observados menores valores das variáveis espirométricas (p<0,01), da força muscular respiratória e dos níveis de L-carnitina nos pacientes do G1; porém, não houve diferença entre os grupos quanto à capacidade de realizar exercício físico dinâmico de baixa intensidade. Correlações significativas entre o percentual de gordura e os níveis de L-carnitina plasmática foram observadas nos pacientes (r=0,53 com p<0,002); sendo que, nos pacientes com índice de massa corporal menor que 18kg/m², essa relação aumentou (r<0,73 com p<0,01). CONCLUSÃO: Na doença pulmonar obstrutiva crônica, a desnutrição está associada tanto aos prejuízos da função pulmonar e da força muscular respiratória, quanto aos baixos níveis de L-Carnitina plasmática.

Condutas terapêuticas para tratamento da Síndrome da Apnéia e Hipopnéia Obstrutiva do Sono (SAHOS) e da Síndrome da Resistência das Vias Aéreas Superiores (SRVAS) com enfoque no Aparelho Anti-Ronco (AAR-ITO)

Os autores apresentam uma revisão da literatura referente às alternativas de tratamento cirúrgicas e não-cirúrgicas para a Síndrome da Apnéia e Hipopnéia Obstrutiva do Sono (SAHOS) e para a Síndrome da Resistência das Vias Aéreas superiores (SRVAS) com enfoque no princípio de ação e evolução dos aparelhos de avanço mandibular e, em particular, no mecanismo dinâmico de ação do Aparelho Anti-Ronco® (AAR-ITO).

Avaliação cefalométrica do espaço aéreo posterior em pacientes com oclusão Classe II submetidos à cirurgia ortognática

OBJETIVO: o avanço maxilomandibular é um método cirúrgico comumente usado no tratamento de pacientes acometidos pela Síndrome da Apnéia Obstrutiva do Sono (SAOS) e portadores de anormalidades anatômicas identificáveis neste complexo, que estreitam e/ou obstruem o espaço aéreo. O intuito deste estudo foi analisar variações cefalométricas do espaço aéreo faríngeo em indivíduos Classe II de Angle, após a cirurgia ortognática. METODOLOGIA: a amostra consistiu de telerradiografias laterais equivalentes aos períodos pré e pós-operatório de 30 indivíduos, divididos no grupo com avanço cirúrgico mandibular (n=15) e no grupo com avanço maxilomandibular (n=15). Os parâmetros cefalométricos usados permitiram avaliar o espaço aéreo posterior em 3 níveis: a hipofaringe (PFI-V), a orofaringe (PFM-PM, PFM-PO, PFM-U, PFM-Up) e a nasofaringe (PFM-PN, pm-PFS). A análise esquelética foi na base do crânio (N-S-Ba) e na mandíbula (Ar-Go-Me). A média das diferenças entre os valores pré e pós-operatórios das mensurações lineares (mm) e angulares (graus) foi avaliada pelo teste t pareado. RESULTADOS E CONCLUSÕES: estatisticamente, não houve redução do espaço aéreo faríngeo pós-avanço cirúrgico. O que se observou foi que apenas PFM-PO e PFS-pM se mantiveram constantes e na maioria restante os valores aumentaram.

Gender differences in predictors of health status in patients with COPD

Objective: To evaluate the health status (HS) of COPD patients and to identify the main predictors of HS in these patients according to gender. Methods: The study included 90 COPD patients (60 males and 30 females; mean age = 64 +/- 9 years) with a wide range of airway obstruction disorders (mean FEV(1) = 56 +/- 19% of predicted). The men were individually matched to the women by % of predicted FEV(1) (ratio: 2:1). The patients were assessed regarding body composition; six-minute walk distance; perception of dyspnea using the Modified Medical Research Council Dyspnea Scale; Saint George's Respiratory Questionnaire (SGRQ); Charlson comorbidity index; and the multidimensional Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) index. Multiple linear regression analysis was performed to identify the predictors of HS by gender. Results: Impairment of HS was greater among the women than among the men for SGRQ total score and for all SGRQ domains (total: 51 +/- 18% vs. 38 19%; p = 0.002; symptoms: 61 +/- 22% vs. 42 +/- 21%; p < 0.001; activity: 62 +/- 18% vs. 49 +/- 21%; p = 0.004; and impact: 41 +/- 19% vs. 27 +/- 18%; p = 0.001). The multiple linear regression showed that age and perception of dyspnea correlated with SGRQ total score for both genders (males, r(2) = 0.42; females, r(2) = 0.70; p < 0.05). Conclusions: Our results showed an association between gender and HS in COPD patients. Age and dyspnea are determinants of HS in both genders.

Pleiotropic effects of statins may improve outcomes in atherosclerotic renovascular disease

BACKGROUNDAtherosclerotic renovascular disease (ARD) coexists with arterial obstructive disease in the coronary, cerebral, and peripheral arteries that may remain underdiagnosed and untreated.METHODSThis retrospective study compares overall survival and renal survival (i.e., time to doubling of serum creatinine or end-stage renal disease (ESRD)) over an 11-year period in 104 ARD patients of whom 68 received statin therapy (group S) because of elevated lipid levels and 36 had no statin (group NS) because of normal lipid profile at entry.RESULTSAtherosclerosis in another vascular bed was documented in 84%. Lipid profiles at end point were virtually identical in both the groups Group S had mean survival 123 months (confidence interval (CI) 113-134) with four deaths, and mean renal survival 122 months (CI 113-131). Group NS had mean survival 33 months (CI 23-42) with 13 deaths, and mean renal survival 27 months (CI 17-37).CONCLUSIONSStatin therapy was associated with lesser rate of progression of renal insufficiency (with 7.4% of S patients reaching renal end points vs. 38.9% of NS patients) and lower overall mortality (5.9% in S vs. 36.1% in NS patients), P < 0.001 for both. Although both groups received what was deemed optimal therapy, they did have other differences that may have affected the outcomes (a limitation addressed by Cox multiple regression analysis). These results suggest the need for prospective randomized controlled studies in ARD patients in order to explore potential benefits of statins that may not be attributable solely to lipid lowering.

Platelet activation in experimental arterial thrombosis.

Platelet aggregates were studied in dogs with induced arterial thrombosis, by the method of Wu and Hoak. Blood was withdrawn from a jugular vein and from the femoral vein on the operated side 24 h after thrombus induction and immediately and 2 h after blood flow was restored by thrombectomy. Platelet activation was significant in dogs with obstructive arterial thrombosis and which tended to subside after thrombectomy. Activation or formation of platelet aggregates seemed to occur in the ischemic limb. It is suggested that this experimental model could be useful to test the action of anti-platelet drugs in vivo.

Paracoccidioidomicose: estudo radiológico e pulmonar de 58 casos

Spirometric and haemogasimetric tests were performed in 52 patients with unifocal and multifocal progressive Paracoccidioidomycosis pulmonary diseases, in 5 patients with juvenile and 1 female internal genital forms. The age ranged from 20 to 74 years old and the duration of disease from 3 to 25 years. Dyspnea, cough, tegumentary and lymphatic manifestations were the most predominant signs observed. Fourteen of them was developed Cor pulmonale. Impaired renal function was recorded in 19 patients, cardiac symptoms were described in 7 and hyporeactor adrenal activity was showed in 13 patients. Radiological studies demonstrated mild in 16, moderate in 24 and severe pulmonary lesions types in 18 patients. The pulmonary function revealed: normal spyrographic findings in 17, pure obstructive type in 32 and mixed form in 9 of them. Hyperventilation was described in 54 individuals and all of them showed an increasing of the alveolo-arterial difference. PaO2 less than 80 mm/Hg observed in 36 of them. Statistical analysis demonstrated significative association between clinical evolution and radiological interpretation. Similar data were obtained in radiology evaluations, clinical evolutive studies and pulmonary functions described in these patients. The granulomatous reaction due to Paracoccidioidomycosis, in heavy smokers patients, gave origin to the alterations in small airways predisposing the interalveolar dissemination an impaired alveolo-arterial diffusion.

Doença pulmonar obstrutiva crônica

Chronic obstructive pulmonary disease (COPD) is an extremely common disorder that all primary care physicians should be able to manage. In this review we will define the entities incorporated in COPD and will present various aspects of the diagnoses and treatment. We could not cover every aspect of this broad topic even providing a detailed review of those areas but some facets of therapy like smoking cessation, drug therapy, oxygen therapy, nutrition, and respiratory rehabilitation will be described.

O uso das pregas cutâneas e da circunferência muscular do braço no diagnóstico de desnutrição energético-protéica em pacientes adultos: estudo crítico.

The use of anthropometric measurements of triceps (TSF) and subscapular skinfolds (SSF) and mid-upper arm muscle circumference (MAMC) was examined as far as the diagnosis of energy-protein malnutrition (EPM) is concerned. The study was undertaken in five groups of patients (n = 231): arterial hypertension (AH, n = 63), chronic obstructive pulmonary disease (COPD, n = 17), hemodialyzed chronic renal failure (CRF, n = 19), critically ill patients with an acute event (CA, n = 42) and critically ill patients with chronic diseases (CCD, n = 90). The results were compared to those obtained in a group of healthy individuals (control group, n = 102). The control group and the group of patients were allocated in subgroups according to sex and age (less than 50 and more than 50 years). It was expected that significant differences would be found for the anthropometric values between the control subgroups and the COPD, the CRF and the CCD subgroups of patients. For the skinfold thicknesses (TSF and SSF), significant differences were found between CRF, CCD subgroups and the control subgroups under fifty years of age; however, the differences were not significant when the subgroups over fifty were analyzed. Concerning the MAMC, significant differences were found: 1 degree) between the CRF subgroups (males and females) and the control subgroups under fifty years of age; 2 degrees) between the CCD male subgroups (younger and older subgroups) and the respective control subgroups and 3 degrees) between the COPD and the control subgroups.(ABSTRACT TRUNCATED AT 250 WORDS)

A comparison of nasopharyngeal endoscopy and lateral cephalometric radiography in the diagnosis of nasopharyngeal airway obstruction

Two auxiliary methods of diagnosing nasopharyngeal airway obstruction were compared. Cephalometric radiography and nasopharyngeal videoendoscopy were evaluated for efficacy in terms of reproducibility and validity. Thirty orthodontic patients (7 to 12 years of age) seeking otorhinolaryngologic treatment for mouth breathing, or mouth and nose breathing, had nasopharyngeal endoscopy and radiographic examinations performed on the same day. Two otorhinolaryngologists analyzed the results. Nasopharyngeal endoscopy was more reliable in identifying all the obstructive nasopharyngeal processes. Endoscopy obtained kappa index scores of almost perfect agreement for diagnosis of posterior nasal septum deviation, of substantial agreement for anterior nasal septum deviation and lower turbinate hypertrophy, and of moderate agreement for middle turbinate hypertrophy. Lateral cephalometric radiography obtained scores of perfect agreement for imaging hypertrophy of the middle turbinate, of almost perfect agreement for imaging hypertrophy of the posterior portion of the inferior turbinate, and of substantial agreement for imaging hypertrophy of the inferior turbinate. Radiographic diagnoses of hypertrophy of the middle and lower turbinates exhibited high sensitivity and low specificity when compared with diagnoses by nasopharyngeal endoscopy.

Perfil demográfico e de morbidade da população idosa atendida nas dependências do pronto-socorro, ambulatórios e enfermarias no HC-Unesp em 1997

Being our objective to characterize demographic and morbidity patterns of the 60 years old or more attended at the UNESP Clinic Hospital in 1997 a sample consisting of 482 handbooks has been analyzed in order to evaluate ambulatory attendance, other consisting of 101 handbooks to evaluate first aid clinic demand and statistics from Medical Informatic Center (Centro de Informática da Medicina - CIMED) refering to 2652 internments of such populations this year. Ten and a half per cent from the total of first aid clinic attended patients refers to this old people and the majority (57,4%) lives in Botucatu County. More frequently diagnoses during consultation are Chronic Obstructive Lung Disease (10.1%), Congestive Cardiac Disease (4.7%), Asthma and Cataract (3.1 % for both). Such population is also referred to be 19.8% from the number of all patients attended at the UNESP ambulatories, 65.8% coming from other city in São Paulo State, being in average 69.6 years old and attending 4.5 consultations in average by year. More frequently found diagnoses referred to Essential Primary Hypertension (4.2%), Prostatic Nodular Hyperplasia (4.0%) and Nonspecified Cataract (3.3%). Regarding to internments, they referred to be 18.4% from the number of all interned patients. More frequent diagnoses at internmemt referred to Nonspecified Cataract (12%), Glaucoma (3.0%), Prostatic Nodular Hyperplasia (2.4%) and Limbs Arteriosclerosis (2.3%). Results indicates the existence of an tertiary hospital divided into specialties, also attending morbidity that should be in control into levels of primary and secondary attention.
