Fístula esôfago-bronco-pleural pós pneumonectomia direita

We report the case of a 42 years old female that presented a simultaneous bronchial and esophagopleural fistula 32 months following a right pneumonectomy for pulmonary tuberculosis. The clinical findings were mainly related to pleural sepsis. The treatment consisted initially in clearing the pleural infection, followed by closure of both fistulae, using muscle flaps and thoracoplasty. The post operative course was uneventful and the patient is doing well over three years later.

O retalho pleural na perfuração do esôfago torácico

The thoracic esophageal perforations frequently complicate with fistula when submitted to primary suture. The use of autogenous tissues, like pleura, to reinforce the primary suture has proved to be useful in reduce the incidence of fistulas or at least the severity of the leaks in case they occur. The mortality has reduced too, consequently. A case of an extensive esophageal perforation is presented, where the use of pleural wrap to reinforce the esophagorrafy was very important to contain the leak and to permit a good evolution of the patient.

Cariótipo Fetal em Líquido Pleural Obtido por Toracocentese

Objetivos: avaliar a efetividade da realização de cariótipo em líquido pleural obtido por toracocentese de um grupo de fetos portadores de derrame pleural. Métodos: foram avaliados 15 fetos com derrame pleural uni ou bilateral nos quais se realizou uma punção da cavidade torácica. A idade gestacional variou entre 19 e 34 semanas. Os fetos foram estudados com ultra-sonografia morfológica para determinar a presença de anomalias associadas. Nos casos em que não se obteve o cultivo em líquido pleural foi realizada cordocentese para a realização do cariótipo. O líquido pleural obtido foi enviado para cultura de linfócitos e cariótipo, sendo a técnica de cultivo semelhante à realizada com sangue. Resultados: dos 15 casos estudados foi obtido cariótipo em 12, e destes, em quatro se encontrou a trissomia do cromossomo 21 e os outros 8 foram normais. Em todos os casos, normais ou alterados, o cariótipo foi confirmado no sangue dos recém-nascidos e por meio do exame neonatal ou da necropsia. Não ocorreram complicações maternas ou fetais relacionadas ao procedimento invasivo. Conclusões: o cariótipo em líquido pleural obtido por toracocentese mostrou ser procedimento eficaz e seguro, devendo ser empregado nos casos de fetos com derrame pleural.

Natural effusions: Mrs J. Howorth’s English translation of Albrecht von Haller’s Die Alpen

Albrecht von Haller's Die Alpen [The Alps] was an immensely popular piece of early eighteenth-century poetry, yet it took more than half a century to be translated into English. In this article I examine Mrs J. Howorth's prose rendering of it in her translated collection The Poems of Baron Haller (1794) and analyse how the translation itself reflects late-eighteenth-century scientific, political and aesthetic concerns, notably through the influence of Linnaeus and Jean-Jacques Rousseau. Secondly, I explore how Howorth constructed a public image of herself as a female consumer and producer of botanical literature, and argue that her translation constitutes an early example of British women's increasing engagement in science through the activity of translation.

Chlorpropamide treatment restores the reduced carrageenan-induced paw edema and pleural exudate volume in diabetic rats

Objective and design: Knowing that hyperglycemia is a hallmark of vascular dysfunction in diabetes and that neonatal streptozotocin-induced diabetic rats (n-STZ) present reduced inflammatory response, we decided to evaluate the effect of chlorpropamide-lowered blood glucose levels on carrageenan-induced rat paw edema and pleural exudate in n-STZ. Materials: Diabetes was induced by STZ injection (160 mg/kg, ip) in neonates (2-day-old) Wistar rats. Treatment: n-STZ diabetic rats were treated with chlorpropamide (200 mg/kg, 15 d, by gavage) 8 weeks after STZ injection. Methods: Carrageenan-induced paw edema and pleural exudate volumes were assessed concomitantly with peripheral and exudate leukocyte count. We also evaluated the expression of inducible nitric oxide synthase (iNOS) in lungs of all experimental groups. Results: Chlorpropamide treatment improved glucose tolerance, beta-cell function (assessed by HOMA-beta), corrected paw edema, and pleural exudate volume in n-STZ. Neither leukocyte count nor iNOS expression were affected by diabetes or by chlorpropamide treatment. Conclusion: Chlorpropamide treatment by restoring beta-cell function, reducing blood sugar levels, and improving glucose tolerance might be contributing to the correction of the reduced inflammatory response tested as paw edema and pleural exudate in n-STZ diabetic rats.

Thorax ultrasound in the management of pediatric pneumonias complicated with empyema

The aim of this work is to prospectively study the value of thoracic ultrasound (US) before pleural drainage in children with parapneumonic effusion (PPE). All children hospitalized for PPE, identified by thoracic radiography, underwent US to assess pleural loculation, echogenicity, and pleural fluid quantity. From August 2001 to July 2003, 52 children were examined. US was performed on 48 of these children, of whom 35 received chest tube drainage and 13 only received clinical treatment. US identified 38 patients with free flowing and 10 with loculated pleural fluid. About 25 of the free flowing (65.8%) and 10 (100%) of the loculated patients received chest tube drainage. Echogenicity was anechoic in 13, echoic without septations in 17 and echoic with septations in 18. Chest tube drainage was required in 6 anechoic (46.15%), 14 echoic without septations (82.35%), and 15 echoic with septations (83.33%). Quantity of fluid estimated by US varied from 20 to 860 ml. Effusion volume was higher in patients that were echoic with septations and loculated effusions. Pleural glucose and pH were lower, and LDH was higher in loculated PPE patients. In conclusion, US is an auxiliary exam for determining whether thoracic drainage is needed in parapneumonic effusion; loculated or echoic effusion should be drained, and free anechoic fluid needs further investigation.

Complicated pneumonias with empyema and/or pneumatocele in children

To investigate the incidence, procedure type, characteristics of pleural fluid and pneumatoceles, and evolution of pneumonia complicated with empyema and/or pneumatoceles. Review of 394 pediatric pneumonia in patients at S (a) over capo Paulo State University Hospital during 2 years. We studied those with complications such as pleural effusion and pneumatocele. There were 121 (30.71%) with complications such as pleural effusion and pneumatocele; these were significantly higher in infants. One hundred and six children were needle aspirated, of these 78 underwent drainage, and 15 observation only. From the drained, seven needed thoracotomy or pleurostomy. Fluid was purulent in 50%, and pneumatoceles were seen in 33 cases (8.3%) with spontaneous involution in 28 (85%). Pleural fluid culture was negative in 51% cases; in positive cultures, Streptococcus pneumoniae was the most common agent. Complicated pneumonia incidence was higher in the second year of life and more than 70% occurred before 4 years of age. Closed thoracic drainage was effective in over 90%. Large effusions and mediastinal deviations were submitted to more aggressive procedures. Pneumatoceles predominated in the under 3s and were generally evident in the first chest X-ray. Most cases had spontaneous pneumatocele involution, and in almost half the cases were still present at drain tube removal.

Three-Dimensional Ultrasonographic Assessment of Fetal Total Lung Volume as a Prognostic Factor in Primary Pleural Effusion

Objectives-The purpose of this study was to predict perinatal outcomes using fetal total lung volumes assessed by 3-dimensional ultrasonography (3DUS) in primary pleural effusion.Methods-Between July 2005 and July 2010, total lung volumes were prospectively estimated in fetuses with primary pleural effusion by 3DUS using virtual organ computer-aided analysis software. The first and last US examinations were considered in the analysis. The observed/expected total lung volumes were calculated. Main outcomes were perinatal death (up to 28 days of life) and respiratory morbidity (orotracheal intubation with mechanical respiratory support >48 hours).Results-Twelve of 19 fetuses (63.2%) survived. Among the survivors, 7 (58.3%) had severe respiratory morbidity. The observed/expected total lung volume at the last US examination before birth was significantly associated with perinatal death (P < .01) and respiratory morbidity (P < .01) as well as fetal hydrops (P < .01) and bilateral effusion (P = .01).Conclusions-Fetal total lung volumes may be useful for the prediction of perinatal outcomes in primary pleural effusion.

Adenocarcinoma in females detected in serous effusions: Cytomorphologic aspects and immunocytochemical reactivity to cytokeratins 7 and 20

OBJECTIVE: To investigate the usefulness of assessing the immunoreactivity of cytokeratins 7 (CK7) and 20 (CK20) as well as several cytomorphologic parameters in effusions with metastatic adenocarcinomas in the search for the primary site of the tumor. STUDY DESIGN: From the files of the Pathology Department, A. C. Camargo Hospital, we studied cytologic smears from 73 metastatic adenocarcinomas originally from the breast, 63 from the ovary, 40 from the lung and 32 from the stomach, looking for morphologic parameters that could have discriminant potential in suggesting the primary site in a routine situation, including intranuclear inclusions, prominent nucleoli, mitosis, signet-ring cells, psammoma bodies, nuclear crease, binucleation and multinucleation, papillary features, acinar profile (including ball cells) and single cells. Immunoreactions were performed with monoclonal antibodies to CK7 (OV-TL 12/30 and CK20 (Ks 20.8) and included morphologic analysis. Both analyses were studied in a blind fashion regarding the primary site of the tumors. RESULTS: Positivity ratios for breast, ovary, stomach and lung cases were 67.6%, 63.5%, 29.7% and 45.5%, respectively, for CK7 and 17.2%, 15.8%, 13.5% and 32.2%, respectively, for CK20. Discriminant analysis of morphologic and immunocytochemical parameters had an error rate of 42.9% in recognizing the primary site and a Wilk's lambda of .7290. CONCLUSION: The more efficient parameter with discriminant function was the papillary appearance showed by CK7, which should be used in further studies with a similar scope. The set of parameters used in this study were insufficient to discriminate the primary site of female adenocarcinomas in effusions with significant accuracy.
