Effectiveness of Saireito, a Traditional Japanese Kampo Herbal Medication, on Pacemaker-Related Pleural Effusion: A Case Report.

BACKGROUND Post-cardiac injury syndrome, including pleural effusion as a delayed complication of permanent pacemaker implantation, has rarely been reported. To resolve pleural effusion, prolonged chest tube placement is often required. Anti-inflammatory agents combined with diuretics are also often prescribed. Saireito, a Japanese herbal medication, which is a combination of Goreisan and Shousaikoto, has both anti-inflammatory and water-modulation properties and has been used for edema (lymph edema, cerebral edema) and inflammation (chronic nephritis). CASE REPORT We describe a 71-year-old woman with a history of syncope and bradycardia who underwent dual permanent pacemaker implantation (placed in the right chest because of a persistent left superior vena cava) without complications. Two months later, she came to the hospital as an outpatient with a dry cough, and was diagnosed with right-sided pleural effusion. A pleural fluid analysis revealed exudative effusion, according to Light's criteria. The fluid was negative for infectious etiology. Chest X-ray, computed tomography, and echocardiography revealed no signs of pericardial effusion or perforation of the pacemaker lead to outside the heart. The pleural effusion persisted despite use of anti-inflammatory medication for several weeks and diuretics for a short period. Saireito was administered with good response; the pleural effusion resolved completely and there was no deterioration of renal function. CONCLUSIONS The present case highlights the clinical significance of Saireito as an effective therapeutic agent for late-onset pacemaker-related pleural effusion, without adverse effects such as renal dysfunction.

Adding positive airway pressure to mobilisation and respiratory techniques hastens pleural drainage: a randomised trial.

QUESTIONS: In patients with a collection of fluid in the pleural space, do mobilisation and respiratory techniques: shorten the drainage period and length of hospital stay; improve respiratory function and oxygenation; and prevent pulmonary complications? Does the addition of positive airway pressure to this regimen further improve the effects? DESIGN: Randomised controlled trial with three intervention arms, concealed allocation, intention-to-treat analysis and blinded assessment. PARTICIPANTS: One hundred and fifty-six inpatients with a fluid collection in the pleural space and with chest drainage in situ. INTERVENTION: Participants received usual care and were randomly assigned to: a control group that also received sham positive airway pressure (4 cmH2O) only (Con); an experimental group that received incentive spirometry, airway clearance, mobilisation and the same sham positive pressure (Exp1); or an experimental group that received the Exp1 regimen except that the positive airway pressure was 15 cmH2O (Exp2). Treatments were provided three times per day for 7 days. OUTCOME MEASURES: Days of chest tube drainage, length of hospital stay, pulmonary complications and adverse events were recorded until hospital discharge. Costs in each group were estimated. RESULTS: The Exp2 group had shorter duration of chest tube drainage and length of hospital stay compared with the Exp1 and Con groups. In addition, the Exp2 group had less antibiotic use (18% versus 43% versus 55%) and pneumonia incidence (0% versus 16% versus 20%) compared with the Exp1 and Con groups (all p < 0.01). The groups had similar rates of adverse events (10% versus 2% versus 6%, p > 0.05). Total treatment costs were lower in the Exp2 group than in the Exp1 and Con groups. CONCLUSIONS: In patients with a fluid collection in the pleural space, the addition of positive pressure to mobilisation and respiratory techniques decreased the duration of thoracic drainage, length of hospital stay, pulmonary complications, antibiotic use and treatment costs.

A 60-Year-Old Woman With Acute Chest Pain and Bilateral Pleural and Pericardial Effusions.

CASE PRESENTATION: A 60-year-old woman presented with acute-onset, progressively worsening shortness of breath and pleuritic chest pain for 3 days. She also complained of a dry cough, but no fever or chills. There was no history of swelling of the feet; nor was there a history of nausea or diarrhea. She was a lifelong nonsmoker and had no history of recent travel or sick contacts. Her medical history included hypertension and ulcerative colitis. The ulcerative colitis was in remission and she had not been taking medications for this for over 7 years. Her home medications included alendronate, amlodipine, aspirin, atenolol, and vitamin D3 supplements. She had no allergies.

Therapeutic lymphangiography for traumatic chylothorax.

Chylothorax is a challenging disease. We present a case of traumatic chylothorax that was successfully treated using lymphangiography through intranodal injection of contrast agent. A 17-year-old girl had chylothorax. It did not improve despite medical treatment. We performed lymphangiography through intranodal injection of an oil contrast agent (Lipiodol). The amount of chylothorax was reduced from 1000 to 120 mL/d, and we could remove the thoracotomy tube. Thereafter, although she had a small amount of pleural effusion, she has not demonstrated aggravation for 19 months. Lymphangiography with oil contrast agent can be one of the options to treat chylothorax.

Fat-Modified Breast Milk Resolves Chylous Pleural Effusion in Infants With Postsurgical Chylothorax but Is Associated With Slow Growth.

BACKGROUND: Chylothorax occurs in ~3%-5% of infants undergoing cardiac surgery. Standard treatment requires discontinuation of breast milk feeding, due to the abundance of long-chain triglycerides and transition to a medium-chain triglyceride (MCT)-based formula. OBJECTIVE: To determine the effectiveness of fat-modified breast milk (MBM) for the treatment of chylothorax compared with MCT formula. MATERIALS AND METHODS: Infants diagnosed with chylothorax following surgery for congenital heart disease between January 2008 and December 2009 at The Hospital for Sick Children were eligible for this nonrandomized open-label study. Treatment infants (n = 8) received mother's own milk that had been modified by removing the fat layer via centrifugation and adding MCT, nutrients, and essential fatty acids to provide an estimated 74 kcal/100 mL and 1.4 g/100 mL protein (MBM group). Control infants (n = 8) received an MCT formula (MCT group). The feeding intervention was a minimum of 6 weeks after chest tube removal per The Hospital for Sick Children standard chylothorax treatment protocol. RESULTS: Daily volume and duration of chest tube drainage were not different between the MBM and MCT groups. While there was no statistically significant difference in rates of weight gain (g/d) between feeding groups, infants in the MBM group, who tended to be younger, experienced a decline in mean weight (P = .04) and length (P = .01) for age z scores. CONCLUSION: Fat-modified breast milk resolved chylothorax; however, strategies to address poor growth need to be developed and evaluated in larger trials prior to widespread clinical adoption of this novel treatment.

The effects of a physiotherapy programme on patients with a pleural effusion: a randomized controlled trial.

OBJECTIVE: To investigate the effects of a physiotherapy protocol on patients with pleural effusion. DESIGN: Randomized controlled trial. SETTING: University hospital. PARTICIPANTS: A total of 104 consecutive inpatients with a medical diagnosis of pleural effusion. INTERVENTION: Patients were randomly allocated to a control group receiving standard treatment (medical treatment and drainage) or an intervention group treated with physiotherapy added to standard treatment. The physiotherapy programme included deep breathing exercises, mobilizations and incentive spirometry. MAIN OUTCOME MEASURES: Spirometric predicted values and chest radiographs were measured before treatment and at discharge and the length of hospital stay was recorded. Assessors were blinded to the intervention. RESULTS: A comparative analysis showed a significant improvement of spirometric parameters in the intervention group; pre-to-post hospitalization predicted values showed significant changes in vital capacity (73.1 ± 12.6% to 72.13 ± 13.7 %, P<0.001 ), forced expiratory volume in first second (72.13 ± 13.7% to 78.98 ± 16.9%, P<0.001) and forced expiratory flow at 25-75 % (64.8 ± 35.1% to 76.78 ± 35.3%, P=0.198) compared to the control group that showed no significant changes across treatment. The radiographic findings showed better scores on the affected side of the thorax at discharge in the physiotherapy group. Length of hospital stay was also significantly (P=0.014) shorter in the intervention group (26.7 ± 8.8 days) compared to the control group (38.6 ± 10.7 days). CONCLUSIONS: A physiotherapy programme added to standard treatment improves the spirometric parameters and the radiological findings and reduces the hospital stay in patients with a pleural effusion.

Novel approach for talc pleurodesis by dedicated catheter through flexi-rigid thoracoscope under local anesthesia.

For pleurodesis, talc administered by poudrage is usually insufflated blindly from a single port of entry using the standard method with a small-diameter rigid thoracoscope. In order to visually perform talc poudrage from a single port, we introduced a catheter technique through a flexi-rigid thoracoscope. Patients with uncontrolled and symptomatic pleural effusion requiring pleurodesis underwent flexi-rigid thoracoscopy under local anesthesia for talc poudrage. A dedicated catheter with 2.1-mm inner diameter was connected to a talc atomizer and inserted through the working channel of the flexi-rigid thoracoscope to insufflate talc into the pleural cavity under visualization. Nine patients were included in this study. Three patients were >75 years old, and two were Karnofsky performance status 50. Three patients received propofol for sedation and six were not sedated. Mean operative time was 30.8 min for all patients, and 21.3 min for cases without sedation. All procedures were performed easily under clear visualization with no major complications or catheter obstructions. This novel approach for talc pleurodesis using a catheter was well-tolerated and seems feasible for patients with uncontrolled pleural effusion. We consider this technique useful even for difficult cases, such as elderly patients or those with relatively low performance status.

Evidence-based suggestions for management of air leaks.

The management of postoperative alveolar air leaks (AALs) continues to challenge thoracic surgeons. AALs increase length of stay and health care costs, and likely lead to other postoperative complications. Staple line buttresses, topical sealants, pleural tents, pneumoperitoneum, and modifications of traditional chest tube management (ie, reduced suction) have all been proposed to help reduce AAL. However, the cost of some of the commercial products being marketed may outweigh their relative effectiveness, and some of these techniques and products have not been adequately studied to date. This article provides a review of the available evidence-based literature that addresses the efficacy of the options currently available to prevent and manage AALs. Management suggestions based on this literature are presented.

Recurrent pleural effusion: who benefits from a tunneled pleural catheter?

Recurrent malignant pleural effusion (MPE) is a common concomitant phenomenon of malignant disease, which can worsen the patient's quality of life and lead to significant morbidity. Tunneled indwelling pleural catheters (TIPC) offer new modalities in patients with recurrent MPE and impaired dilatability of the lung. We report on our experience with 100 consecutive patients suffering from recurrent benign (n = 12) and malignant pleural effusion (n = 88) who were treated with TIPC. The catheter was placed during a VATS procedure or under local anesthesia in an open technique. The median residence time of the TIPC was 70 days; spontaneous pleurodesis was achieved in 29 patients. The rate of complications was low: pleura empyema (n = 4), accidental dislodgement (n = 2), malfunction of the drainage (n = 3). In conclusion, TIPC is a useful method for the palliative treatment of patients with recurrent malignant or nonmalignant pleural effusions and 3 groups of patients seem to benefit most: a) patients with the intraoperative finding of a trapped lung in diagnostic VATS procedure; b) patients after a history of repeated pleuracenteses or previously failed attempts at pleurodesis; c) patients in a reduced condition with a limited lifespan due to underlying disease.

Percutaneous radiological management of high-output chylothorax with CT-guided needle disruption.

We present the study of a 58-year-old man who underwent percutaneous management of a high-output chylothorax following cardiac bypass graft surgery. The patient presented to a peripheral hospital 3 weeks postoperatively following cardiac bypass graft surgery with shortness of breath. A chest radiograph taken on arrival to the emergency department showed a large left-sided pleural effusion. Subsequent intercostal chest tube insertion drained a large amount of chylous fluid. The patient was treated conservatively with no improvement until undergoing a CT-guided needle disruption of lymphatics with good effect. This case is presented to show the minimally invasive treatment methods that are available in the management of high-output chylothorax.

Cerebral gas embolism caused by pleural fibrinolytic treatment.

BACKGROUND AND PURPOSE: Intrapleural fibrinolytic therapy is a technique used to treat empyemas and parapneumonic effusions. Cerebral air embolism is an unusual potentially severe complication of this technique. Summary of Case- A patient with parapneumonic pleural effusion underwent pleural lavage with streptokinase when he suddenly demonstrated focal neurological signs and seizures. The CT revealed multiple air-isodense spots in right hemisphere of the brain, suggesting cerebral air embolism. As a result of early diagnosis and emergency hyperbaric oxygenation, the patient recovered without delayed sequelae. CONCLUSIONS: Air embolism is a potentially severe complication which can occur during fibrinolytic pleural lavage, and clinicians should be aware of this risk. In this context, the onset of acute focal neurological signs or seizures should suggest the possibility of air embolism and lead to the transfer of the patient close to a hyperbaric facility within a few hours.

Prenatal diagnosis and perinatal management of maternal-fetal congenital parvovirus B19 infection.

OBJECTIVE: In nonimmune pregnant woman, the primary infection with parvovirus B19 may lead to transplacental transmission to the fetus with variable outcomes, including congenital anemia, hydrops fetalis, fetal death or spontaneous resolution. CASE REPORT: The first case was of a 28-year-old woman, gravida 2, para 1, whose fetus was found to have left-sided pleural effusion on a sonogram at 29 weeks of gestation. A sample of aspirated pleural fluid was positive for parvovirus B19 by polymerase chain reaction. Cordocentesis showed fetal hemoglobin level of 5.0 g/dL. Intraperitoneal transfusion (IPT) was performed, because access to the fetal circulation was difficult. Thirty milliliters of group O, Rh-positive packed red cells were transfused into the peritoneal cavity. A non-hydropic baby weighing 2,680 g was delivered at 33 weeks of gestation. The neonates complete blood count examination showed a hemoglobin level of 16.3 g/dL. The newborn baby was discharged in stable condition. The second case was of a 31-year-old woman, gravida 2, para 1, whose fetus was found to have ascites, hypertrophic cardiomyopathy, and placentomegaly on a sonogram at 23 weeks of gestation. An amniotic fluid sample was positive for parvovirus B19 DNA by polymerase chain reaction. Fetal ascites and hypertrophic cardiomyopathy gradually resolved after maternal iron supplementation and 2 weeks of intrauterine digitalization therapy. A healthy infant weighing 3,198 g was delivered at 37 weeks of gestation. The neonates complete blood count examination showed a hemoglobin level of 10.3 g/dL. CONCLUSION: Termination of pregnancy is rarely indicated, because B19 virus is not teratogenic. Although intravascular transfusion offers obvious theoretical advantages, in some cases in which access to the fetal circulation is difficult or impossible, IPT should be performed combined with appropriate medical treatment. Thus, there is still a place for IPT in modern management of the severely anemic fetus, and this technique should not be neglected.

Experimental pleurodesis induced by antibiotics (macrolides or quinolones).

PURPOSE: Chemical pleurodesis is a therapeutic tool for the treatment of recurrent pleural effusions, mainly those of neoplastic etiology. In the past, tetracycline was the sclerosant agent of choice in clinical practice, but presently, there is no consensus about an ideal agent. The aim of this study was to evaluate the effectiveness of macrolides (azithromycin and clarithromycin) or quinolones (levofloxacin and gatifloxacin) in inducing experimental pleurodesis in rabbits. METHOD: Forty New Zealand rabbits randomized into groups of 10 received (at a total volume of 2 mL for each animal) 1 of the 4 drugs by intrapleural injection. After 28 days, the animals were euthanized and the pleural cavity was evaluated macroscopically and microscopically. RESULTS: The intensity of the macroscopic adhesions was mild in all groups. On microscopic analysis, minimal pleural fibrosis and inflammation were observed in all animals. CONCLUSION: The macrolides (azithromycin or clarithromycin) and the quinolones (levofloxacin or gatifloxacin) when injected into the normal pleural space of rabbits are not effective in promoting pleurodesis. Additional research is required to identify sclerosing agents capable of inducing pleurodesis.

[Videothoracoscopy in local anesthesia diagnosis and therapy of pleural effusions]. / Videotorakoskopie v lokální anestezii v diagnostice a lécbe pohrudnicních výpotku.

Videothoracoscopy (VTS) has been performed in the Department of Pneumology in Plzen since the year 2001. Up to-September 2005 there were realized 75 videothoracoscopies, all under local anaesthesia with analgosedation and during the spontaneous ventilation. The objective of the present work is to demonstrate that the so called "medical" videothoracoscopy is very well tolerated, quick and accurate miniinvasive method of examination of pleural pathological states, which has a high diagnostic effect and minimal complications. During the exploration it is possible to carry out, besides the collection of bioptic samples from parietal as well as visceral pleura, a whole range of therapeutical acts - evacuation of effusion, mechanical disruption of adhesions in case of empyema with its subsequent drainage or pleurodesis with talc in case of malignant exudates. As for the basic indication of the medica VTS, we consider it to be the differential diagnosis of a pleural effusion of unclear etiology, consisting mostly in the confirmation or exclusion of malignant exudates. The differential diagnosis with the help of VTS between the nonmalignant (mostly inflammatory) and malignant exudate was successful, in our group of patients, in 96 %. The operation was well tolerated by all patients and in none of them occurred significant complications or consequences.
