    Objective: To discuss the cases and treatment of pericardial tamponade (PT) occurred in the interventional management for Budd-Chiari syndrome (BCS). Methods: During the period from 1990 to 2006, interventional treatment was performed in 812 patients with BCS. Pericardial tamponade occurred in nine patients during the period of interventional treatment. The clinical data, including angiographic findings, clinical symptoms, management and outcomes, of the nine patients were retrospectively analyzed. The possible causes of pericardial tamponade were discussed. Results: Of the nine patients occurring pericardial tamponade, successful treatment was obtained in eight and death occurred in one. The lesions of BCS in the nine cases included inferior vena cava obstruction type (n=7), hepatic venous obstruction type (n=1) and mixed type (n=1). Pericardial tamponade was caused by mistakenly puncturing into pericardium (n=5), mistakenly puncturing together with laceration of pericardium by balloon (n=3), and breaking of pericardium by displaced stent (n=1). Conventional pericardicentesis was employed in one case, surgery was carried out in three cases, and infra-xiphoid catheterization and drainage using Seldinger technique was performed in two cases. Conservative treatment was adopted in one case and aspiration through the wrongly inserted catheter was tried in one case. In the remaining one case, aspiration through the wrongly inserted catheter together with infra-xiphoid catheterization and drainage by using Seldinger technique was carried out. Conclusion: The pericardial tamponade is an severe complication occurred in the interventional management for Budd-Chiari syndrome, although it is rarely seen. Preoperative prevention, prompt detection and rational treatment are the keys avoid serious consequences. (authors)

    The use of a central venous catheter (CVC) has become commonplace in the care of children with a wide variety of medical and surgical problems. Complications resulting from the insertion of these catheters are well recognized and can be life-threatening. When a temporary CVC or other catheter is inserted into the central venous system it is secured to the skin with a combination of sutures and sterile dressing. This fixes the catheter in place and does not allow it to retract, thereby putting pressure on the right atrial wall via the catheter tip if it is too long. The probability of wall penetration is increased if a catheter or device is tapered at the point of contact. The purpose of this case report is to present the bowed catheter sign and to review the anatomy of the cavotricuspid isthmus, a possible predisposing factor to cardiac perforation and tamponade.

    A 48-year-old man presented with complaints of shortness of breath and lower extremity swelling. His medical history was significant for hypertension on minoxidil and recent intracerebellar hemorrhage. Electrocardiography showed sinus tachycardia with left ventricular hypertrophy, and cardiomegaly was noted in the chest x-ray. The patient was hypertensive and tachypneic on admission. An echocardiogram taken immediately showed a large pericardial effusion with evidence of cardiac tamponade. He underwent immediate pericardiocentesis with drainage of 900 mL of pericardial fluid with significant improvement in the symptoms. Analysis of the pericardial fluid proved to be nondiagnostic. Infectious and rheumatologic causes were ruled out. After an extensive battery of tests, not yielding any diagnostic results, the pericardial effusion was attributed to minoxidil therapy. Closer monitoring is needed to prevent potentially fatal complications such as cardiac tamponade as in our patient.

    Full Text Available The authors describe a case of pericardial effusion accompanied by cardiac tamponade caused by primary hypothyroidism. Diagnosis was made by exclusion, because other causes of cardiac tamponade are more frequent. Emergency treatment of cardiac tamponade is pericardiocentesis (with possible pericardial window, and, after stabilization, performance of hormonal reposition therapy with L-thyroxin.

    Full Text Available Here, we report a case of a 51-year-old man with acute pericardial tamponade requiring emergency pericardiocentesis after he suffered from sore throat, headache, malaise, and sweats for two weeks. Serological analyses revealed increased mumps IgM and IgG indicating an acute mumps infection whereas other bacterial and viral infections were excluded. In addition, MRI revealed atypical swelling of the left submandibular gland. Whereas mumps has become a rare entity in children due to comprehensive vaccination regimens in western civilizations, our case highlights mumps as an important differential diagnosis also in adults, where the virus can induce life-threatening complications such as pericardial tamponade.

    Central venous cannulation is widely used in neonatal critical care. Pericardial tamponade caused by vessel wall perforation can occur if the catheter tip induces extravasation at the level of the pericardium. To investigate the level of the superior pericardial reflection in stillborn babies. We dissected 20 bodies (11 female, mean gestational age 33 6/7 weeks, range 25-43 weeks), with careful opening of the thoracic area. After injecting contrast medium into the pericardial sac, we introduced a catheter through the right internal jugular vein. We then took radiographs to analyse the relationship between visual osseous landmarks and the pericardium. Mean distance between the pericardial reflection at its upper end and the first thoracic vertebra was 1.3 cm (standard deviation [SD]: 0.3 cm) and did not extend over the 3rd intercostal space. The mean distance from the entry of the superior vena cava into the pericardial sac and the 1st thoracic vertebra was 2.3 cm (SD: 0.5). The upper end of the pericardial reflection in neonates at autopsy lies below the middle of the 3rd thoracic vertebra. The tip of an upper inserted catheter should not extend below the level of the 3rd intercostal space. (orig.)

    Full Text Available This review article discusses two clinical cases of patients presenting to the emergency department with pericardial effusions. The role of bedside ultrasound in the detection of pericardial effusions is investigated, with special attention to the specific ultrasound features of cardiac tamponade. Through this review, clinicians caring for patients with pericardial effusions will learn to rapidly diagnose this condition directly at the bedside. Clinicians will also learn to differentiate between simple pericardial effusions in contrast to more complicated effusions causing cardiac tamponade. Indications for emergency pericardiocentesis are covered, so that clinicians can rapidly determine which group of patients will benefit from an emergency procedure to drain the effusion.

    The authors drained eight pericardial effusions on an emergency basis because of profound symptoms of pericardial tamponade. The etiology of the pericardial was metastatic disease in all eight cases. US of the subxyphoid region allowed definition of an optimal percutaneous approach. The pericardium was initially punctured with a 22-gauge needle, followed by tract dilation over a wire, which allowed ultimate placement of either an 8.4-F or 10-F nephrostomy catheter. Some 500 - 1,500 ml of bloody fluid drained from the pericardial space within minutes, and a total of 2 - 4 L over the next 4 days. No significant arrhythmias or immediate hypotensive episodes were observed. Six of the patients were successfully treated with sclerosis of the pericardium by injection of tetracyline into the pericardial catheter before it was removed. No recurrent effusions have been observed in any of these patients. Two patients died, one of unsuspected cerebral edema and uncal herniation and one of intractable congestive heart failure. At autopsy, the pericardial catheter was properly positioned with no significant remaining fluid. Echocardiograms were falsely normal in two patients, but CT findings were uniformly diagnostic. Radiologically guided drainage of large pericardial effusions appears to be a safe and effective technique for the treatment of pericardial tamponade from metastatic effusions. This technique is an alternative to the usual surgical intervention and does not require general anesthesia

    While not free from hazards, CT-guided biopsy of the lung is a safe procedure, with few major complications. Despite its safety record, however, potentially fatal complications do rarely occur. We report a case of pericardial tamponade following CT-guided lung biopsy. Rapid diagnosis and therapy allowed for complete patient recovery. Physicians who perform this procedure should be aware of the known complications and be prepared to treat them appropriately.

    Full Text Available We report a case of a 25-year-old lady who presented to our department with complaints of easy fatigability and shortness of breath since one week. She had a history of Raynaud’s phenomenon. Examination revealed scleroderma like skin changes and pericardial friction rub. Investigations revealed high titer of anti-U1 RNP antibodies along with co-existing pancytopenia. Chest x-ray and echocardiography confirmed pericardial tamponade. Patient was diagnosed as having mixed connective tissue disorder (MCTD and she was started on high dose prednisolone, which led to complete reversal of pancytopenia and pericardial tamponade after 1 month of treatment. There are only 6 reported cases of pericardial tamponade in a patient with MCTD, and none of them had pancytopenia. Present case highlights the need to investigate the patient of pericardial tamponade for MCTD, especially in the presence of pancytopenia and relevant clinical history, as prompt treatment with corticosteroids can avoid invasive procedures like pericardiocentesis.

    present. Pericardial drainage is mandatory when clinical tamponade is present. In the absence of clinical tamponade, examination of the pericardial fluid is indicated when there is a clinical suspicion of purulent pericarditis and in patients with underlying neoplasia. Patients with chronic massive idiopathic pericardial effusion should also be submitted to pericardial drainage because of the risk of developing unexpected tamponade. The selection of the pericardial drainage procedure depends on the etiology of the effusion. Simple pericardiocentesis is usually sufficient in patients with acute idiopathic or viral pericarditis. Purulent pericarditis should be drained surgically, usually through subxiphoid pericardiotomy. Neoplastic pericardial effusion constitutes a more difficult challenge because reaccumulation of pericardial fluid is a concern. The therapeutic possibilities include extended indwelling pericardial catheter, percutaneous pericardiostomy and intrapericardial instillation of antineoplastic and sclerosing agents. Massive chronic idiopathic pericardial effusions do not respond to medical treatment and tend to recur after pericardiocentesis, so wide anterior pericardiectomy is finally necessary in many cases.

    Hypothyroidism is a significant cause of pericardial effusion. However, large pericardial effusions due to hypothyroidism are extremely rare. Hormone replacement therapy is the cornerstone of treatment for hypothyroidism and regular follow-up of patients after initiation of the therapy is indicated. Herein, the case of a 70-year-old woman with a massive pericardial effusion due to Hashimoto's disease is presented. A 70-year-old female from a rural village on the island of Crete, Greece, was admitted to our hospital due to a urinary tract infection. She was under hormone replacement therapy with levothyroxine 100 µg once a day for Hashimoto's disease. Two years previously, the patient had had an episode of pericarditis due to hypothyroidism and had undergone a computed tomography-guided pericardiocentesis. The patient did not have regular follow-up and did not take the hormone replacement therapy properly. On admission, the patient's chest X-ray incidentally showed a possible pericardial effusion. The patient was referred for echocardiography, which revealed a massive pericardial effusion. Beck's triad was absent. Thyroid hormones were consistent with subclinical hypothyroidism: thyroid-stimulating hormone (TSH) 30.25 mIU/mL (normal limits: 0.25-3.43); free thyroxin 4 0.81 ng/dL (normal limits: 0.7-1.94). The patient had a score of 5 on the scale outlined by the European Society of Cardiology (ESC) position statement on triage strategy for cardiac tamponade and, despite the absence of cardiac tamponade, a pericardiocentesis was performed after 48 hours. The patient was treated with 125 µg levothyroxine orally once daily. This was a rare case of an elderly female patient from a rural village with chronic massive pericardial effusion due to subclinical hypothyroidism without cardiac tamponade. Hypothyroidism should be included in the differential diagnosis of pericardial effusion, especially in a case of unexplained pericardial fluid. Initiation of hormone

    Full Text Available Abstract Objectives Pericardial tamponade after cardiac surgery is difficult to diagnose, thereby rendering timing of rethoracotomy hard. We aimed at identifying factors predicting the outcome of surgery for suspected tamponade after cardio-thoracic surgery, in the intensive care unit (ICU. Methods Twenty-one consecutive patients undergoing rethoracotomy for suspected pericardial tamponade in the ICU, admitted after primary cardio-thoracic surgery, were identified for this retrospective study. We compared patients with or without a decrease in severe haemodynamic compromise after rethoracotomy, according to the cardiovascular component of the sequential organ failure assessment (SOFA score. Results A favourable haemodynamic response to rethoracotomy was observed in 11 (52% of patients and characterized by an increase in cardiac output, and less fluid and norepinephrine requirements. Prior to surgery, the absence of treatment by heparin, a minimum cardiac index 2 and a positive fluid balance (> 4,683 mL were predictive of a beneficial haemodynamic response. During surgery, the evacuation of clots and > 500 mL of pericardial fluid was associated with a beneficial haemodynamic response. Echocardiographic parameters were of limited help in predicting the postoperative course, even though 9 of 13 pericardial clots found at surgery were detected preoperatively. Conclusion Clots and fluids in the pericardial space causing regional tamponade and responding to surgical evacuation after primary cardio-thoracic surgery, are difficult to diagnose preoperatively, by clinical, haemodynamic and even echocardiographic evaluation in the ICU. Only absence of heparin treatment, a large positive fluid balance and low cardiac index predicted a favourable haemodynamic response to rethoracotomy. These data might help in deciding and timing of reinterventions after primary cardio-thoracic surgery.

    Although pericardial effusion is often identified using non-gated chest computed tomography (CT), findings predictive of cardiac tamponade have not been adequately established. To determine the findings predictive of clinical cardiac tamponade in patients with moderate to large pericardial effusion using non-gated chest CT. We performed a retrospective analysis of 134 patients with moderate to large pericardial effusion who were identified from among 4581 patients who underwent non-gated chest CT. Cardiac structural changes, including right ventricular outflow tract (RVOT), were qualitatively evaluated. The inferior vena cava ratio with hepatic (IVCupp) and renal portions (IVClow) and effusion size were measured. The diagnostic performance of each structural change was calculated, and multivariate analysis was used to determine the predictors of cardiac tamponade. Of the 134 patients (mean age, 70.3 years; 64 men), 37 (28%) had cardiac tamponade. The sensitivity and specificity were 76% and 74% for RVOT compression; 87% and 84% for an IVClow ratio ≥0.77; and 60% and 77% for an effusion size ≥25.5 mm, respectively. Multivariate logistic regression analysis demonstrated that RVOT compression, an IVClow ratio ≥0.77, and an effusion size ≥25.5 mm were independent predictors of cardiac tamponade. The combination of these three CT findings had a sensitivity, specificity, and accuracy of 81%, 95%, and 91%, respectively. In patients with moderate to large pericardial effusion, non-gated chest CT provides additional information for predicting cardiac tamponade. © The Foundation Acta Radiologica 2015.

    CASE DESCRIPTION A 1-year-old castrated male German Shepherd Dog was examined because of an acute onset of lethargy, tachypnea, and inappetence. CLINICAL FINDINGS On initial physical examination, the dog was tachypneic with muffled heart sounds on thoracic auscultation and a palpable abdominal fluid wave. Transthoracic echocardiography revealed focal intramural pericardial effusion and cardiac tamponade. TREATMENT AND OUTCOME The patient underwent emergency therapeutic pericardiocentesis, followed by right lateral intercostal thoracotomy and subtotal pericardiectomy. A 3 × 5-cm mass located between the parietal and visceral layers of the pericardium was resected. The histologic diagnosis was necrotic adipose tissue with granulomatous inflammation and fibroplasia. The patient also underwent exploratory laparotomy and umbilical herniorrhaphy during the same anesthetic episode and recovered from surgery without apparent complications. There were no further clinical signs of cardiac disease. CLINICAL RELEVANCE The patient described in the present report underwent successful subtotal pericardiectomy for treatment of a benign focal lesion causing recurrent pericardial effusion and cardiac tamponade. Prompt diagnosis and intervention may have contributed to the positive outcome in this case.

  1. Pericardial Effusion and Pericardiocentesis: Role of Echocardiography

    Science.gov (United States)

    2012-01-01

    Pericardial effusion can develop from any pericardial disease, including pericarditis and several systemic disorders, such as malignancies, pulmonary tuberculosis, chronic renal failure, thyroid diseases, and autoimmune diseases. The causes of large pericardial effusion requiring invasive pericardiocentesis may vary according to the time, country, and hospital. Transthoracic echocardiography is the most important tool for diagnosis, grading, the pericardiocentesis procedure, and follow up of pericardial effusion. Cardiac tamponade is a kind of cardiogenic shock and medical emergency. Clinicians should understand the tamponade physiology, especially because it can develop without large pericardial effusion. In addition, clinicians should correlate the echocardiographic findings of tamponade, such as right ventricular collapse, right atrial collapse, and respiratory variation of mitral and tricuspid flow, with clinical signs of clinical tamponade, such as hypotension or pulsus paradoxus. Percutaneous pericardiocentesis has been the most useful procedure in many cases of large pericardial effusion, cardiac tamponade, or pericardial effusion of unknown etiology. The procedure should be performed with the guidance of echocardiography. PMID:23236323

    This study was designed to evaluate the safety and efficacy of CT-guided drainage of the pericardial effusion in patients after cardiac surgery. The study included 128 consecutive patients (82 males, 46 females; mean age 66.6 years, SD: 4.2) complicated by pericardial effusion or hemopericardium after cardiac surgeries between June 2008 and June 2016. The medical indication for therapeutic pericardiocentesis in all patients was hemodynamic instability caused by pericardial effusion. The treatment criteria for intervention were evidence of pericardial tamponade with ejection fraction (EF) effusion was 260 ml (range 80-900 ml; standard deviation [SD]: ±70). Directly after pericardiocentesis, there was a significant improvement of the ejection fraction to 40-55% (mean: 45%; SD: ±5; p effusion drainage was 10%. The drainage was applied anteriorly (preventricular) in 39 of 128 (30.5%), retroventricularly in 33 of 128 (25.8%), and infracardiac in 56 of 128 (43.8%). Recurrence rate of pericardial effusion after removal of drains was 4.7% (67/128). Complete drainage was achieved in retroventricular and infracardiac positioning of the catheter (p effusion is a minimally invasive technique for the release of the tamponade effect of the effusion and improvement of cardiac output.

    Full Text Available Abstract Introduction Cardiac tamponade is a rare manifestation of hypothyroidism, and a less rare cause of pericardial effusion. The accumulation of the pericardial fluid is gradual, and often does not compromise cardiac hemodynamic function. There is a relationship between the severity and chronicity of the disease with the presence of pericardial effusion. There are few cases describing associated pericardial tamponade published in the literature. When a tamponade occurs, a concomitant provocative factor such as a viral pericarditis may be related. Our patient's case appears to be the youngest patient described so far. Case presentation We report the case of a previously healthy five-year-old Hispanic (non-indigenous boy who developed rhabdomyolysis with a history of a recent pericardial effusion and tamponade two months before that required the placement of a percutaneous pericardial drainage. Pericardial effusion was considered to be viral. Later on readmission, clinical primary hypothyroidism was diagnosed and thought to be associated with the previous cardiac tamponade. He developed rhabdomyolysis, which was considered to be autoimmune and was treated with steroids. The level of creatine phosphate kinase and creatine kinase MB fraction returned to within the reference rangeone week after our patient was started on steroids and three weeks after he was started on thyroid hormones. Conclusions Physicians should consider hypothyroidism as a differential diagnosis in patients with pericardial effusion. Pericardial effusion may progress and cause a cardiac tamponade with hemodynamic instability. The fact that our patient did not have any manifestations of hypothyroidism might have delayed diagnosis.

    We present a rare case of a central venous catheter-malposition-induced life-threatening cardiac tamponade as a result of computed tomography (CT) with contrast enhancement in an infant with a ventricular septal defect and pulmonary atresia after a modified Blalock-Taussig shunt. The diagnosis was confirmed by chest radiographs and CT study with catheter perforation through the right atrial wall and extravasation of the contrast medium into the pericardium, leading to cardiac tamponade and subsequent circulatory collapse. Two hours after successful cardiopulmonary resuscitation, the patient gradually resumed normal hemodynamic status

    Assessing the role played by angiotensin in the pathogenesis and maintenance of the renal function and perfusion abnormalities dogs with chronic pericardial tamponade were used in the experiment as a stable model of chronic low output heart failure. The heptapeptide and octapeptide antagonist were used. The results of the experiments suggest that there is a role for angiotensin in the pathologenesis of congestive heart failure. The renin-angiotensin system was activated in the model. Plasma renin activity was elevated and increased further in response to angiotensin blockade. Under the experiment condition there was no evidence for a role for angiotensin in the maintenance of arterial blood pressure. But there was angiotensin-mediated renal vasoconstriction and a reduction in renal blood flow. Both analogues of angiotensin were able to antagonize this effect in similar fashion. Failure to achieve a natriuresis in response to angiotensin blockade may reflect the redistribution of blood flow that occured and suggests that additional factors are operative in this model. (APR)

    The percutaneous treatment of pericardial effusion resulting in cardiac tamponade has undergone an evolution in recent years with the use of less invasive drainage techniques in selected cases. To determine optimal therapy modalities for oncology patients with malignant pericardial tamponade (MPT), the authors review their institutional experience with percutaneous needle puncture routes, means of imaging-guided drainage and percutaneous management of the pericardial fluid effusion (pericardial sclerosis and balloon pericardiotomy). Advantages and limits of the percutaneous techniques will be compared to the surgical treatment. (orig.)

    Full Text Available A 50-year-old Caucasian female presented for a second opinion regarding a newly diagnosed pericardial effusion. Seven months previously, hydrochlorothiazide was introduced into her pharmacologic regimen to aid in the management of her hypertension. A routine echocardiogram indicated a large pericardial effusion with signs of early cardiac tamponade. The patient subsequently underwent successful pericardiocentesis with complete drainage of the pericardial effusion. The effusion was empirically attributed to a viral etiology. Repeat echocardiograms showed recurrence of the pericardial effusion. Prior to undergoing a second pericardiocentesis with pericardial biopsy, as her physicians recommended, the patient sought a second opinion. While obtaining the patient’s history, an allergy to sulfa was elicited. The possibility that the pericardial effusion may be secondary to an immunologic-hypersensitivity reaction was considered. It was recommended the patient discontinue the use of hydrochlorothiazide. Nine days following discontinuation of hydrochlorothiazide and without any other intervention, an echocardiogram was reported to show the size of the pericardial effusion had subsided substantially. Nine weeks following discontinuation, almost complete resolution of the pericardial effusion was reported. It is hypothesized that when treated with hydrochlorothiazide, the patient had an immune response leading to the pericardial effusion.

    Clinical manifestations of pericardial disease may precede other signs and symptoms associated with systemic lupus erythematosus. Although pericardial effusion is one of the most common cardiac problems in patients with systemic lupus erythematosus, haemodynamically significant effusions manifesting as cardiac tamponade are rare and require prompt diagnosis and treatment.

    The successive occurrence of pericardial tamponade and myocarditis during a Churg-Strauss syndrome is exceptionally described. We report a patient in whom pericardial tamponade and myocarditis were the presenting manifestation of a Churg-Strauss syndrome. A 58-year-old woman was admitted because of alteration of the clinical status with eosinophilia. One month ago, she was hospitalized for a pericardial tamponade treated by pericardial drainage. Acute myocarditis was diagnosed on chest pain during the second hospitalization. The etiologic inquiry ended in the diagnosis of Churg-Strauss complicated with a double cardiac involvement. A good response of clinical and biological anomalies was obtained after corticosteroid and immunosuppressive treatment. Isolated or multiple involvements of cardiac tunics should lead to make diagnosis of systemic vasculitis. A complete initial assessment and a close observation of the patients followed for Churg-Strauss syndrome is imperative to detect a cardiac achievement and set up an early treatment.

    Full Text Available The frequency of pericardial involvement in Systemic Sclerosis (SSc is high on autoptic or echocardiographic studies, but the clinical recognition of pericarditis with or without effusion is rare. We describe a case of a 71-year-old female with no previous history of heart disease, who presented with a large pericardial effusion and tamponade that required pericardial drain. She had suffered from Raynaud’s phenomenon since 25 years. Six weeks after hospital discharge she complained of skin hardening on left leg. Pericardial tamponade is a very rare manifestation of SSc and occurs both early or late in the course of the disease, but in our case it preceded the recognition of scleroderma. We have only identified two other cases of pericardial effusion preceding cutaneous involvement in scleroderma.

    The pathogenesis of the idiopathic inflammatory myopathies has been postulated to be an environmental trigger causing the expression of the disease in a genetically predisposed patient. We report a case of anti-Jo1 antibody-positive myositis which was associated with pleural effusions, pericardial effusion with tamponade, and 'mechanic's hands', probably related to the consumption of a fermented Kombucha beverage. Kombucha 'mushroom', a symbiosis of yeast and bacteria, is postulated to be the trigger for our patient's disease owing to the proximity of his symptoms to the consumption of the Kombucha beverage.

    Cardiac tamponade secondary to systemic lupus erythematosus is rare and has a very serious prognosis. The authors report a case of cardiac tamponade confirmed by echocardiography, which constituted the presenting sign of systemic lupus erythematosus in a 20-year-old patient, who required emergency pericardial aspiration. The diagnosis of systemic lupus erythematosus was established on the basis of the combination of pericardial involvement, non-erosive arthritis, leukopenia with lymphopenia, presence of LE cells and anti-native DNA antibodies and positive antinuclear antibody titre of 1/2560. The clinical course was favourable in response to 3 months of corticosteroid treatment. The possibility of SLE should be considered in any case of cardiac tamponade in a young patient in which the aetiology is not explained.

    Full Text Available Cardiac involvement in malignant lymphoma is one of the least investigated subjects. Pericardial effusion is rarely symptomatic in patients of Hodgkin lymphoma (HL. Few case reports are available in the literature. There are case reports of diagnosed HL patients presenting with pericardial effusion. HL patients who present with recurrent episodes of pericardial effusion have also been reported. Pericardial effusion has also been reported in cases of non HL. However, pericardial effusion leading to cardiac tamponade as an initial presentation of HL is extremely rare. Very few such cases are there in the literature. Here, we present a case of a 26-year-old male patient who presented with cardiac tamponade and in due course was found to be a case of classical type of HL. This case is interesting because of its presentation.

    Pneumopericardium is a rare disease defined as the presence of air or gas in the pericardial sac. Among the etiological factors, the following stand out: chest trauma, barotrauma, air-containing fistulas between the pericardium and the surrounding structures, secondary gas production by microorganisms growing in the pericardial sac, and iatrogenic factors. Until now, spontaneous pneumopericardium has been considered a harmless and temporary state, but a review of clinical cases indicates that the presence of air in the pericardium can lead to cardiac tamponade and life-threatening hemodynamic disturbances. We present the case of an 80-year-old patient with a chronic bronchopericardial fistula, who suffered from a cardiac arrest due to air tamponade of the heart.

    Full Text Available History of present illness: A 47-year-old female with metastatic breast cancer presented to the Emergency Department with chest pain and shortness of breath. She was hypotensive and her EKG showed sinus tachycardia with low voltage. A bedside ultrasound was performed that detected a pericardial effusion and evidence of cardiac tamponade. The patient’s vitals improved with a fluid bolus and she went emergently to the cardiac catheterization lab for fluoroscopy and echocardiography guided pericardiocentesis. A total of 770 mL of fluid was removed from her pericardial space. Significant findings: The video shows a subxiphoid view of the heart with evidence of a large pericardial effusion with tamponade – note the anechoic stripe in the pericardial sac (see red arrow. This video demonstrates paradoxical right ventricular collapse during diastole and right atrial collapse during systole which is indicative of tamponade.1,2 Figure 1 is from the same patient and shows sonographic pulsus paradoxus. This is an apical 4 chamber view of the heart with the sampling gate of the pulsed wave doppler placed over the mitral valve. The Vpeak max and Vpeak min are indicated. If there is more than a 25% difference with inspiration between these 2 values, this is highly suggestive of tamponade.1 In this case, there is a 32.4% difference between the Vpeak max 69.55 cm/s and Vpeak min 46.99 cm/s. Discussion: Cardiac tamponade is distinguished from pericardial effusion by right ventricular compression/collapse and hemodynamic instability. Findings can include hypotension, tachycardia, distant heart sounds, and jugular venous distension.3,4 One might also see a plethoric IVC without respiratory variation indicative of elevated right atrial pressures.1 Detection of right ventricular collapse for cardiac tamponade has sensitivities ranging from 48%-100% and specificities ranging from 33%-100%.5 A larger effusion is more likely to lead to cardiac tamponade.

    The complication rate following radiofrequency catheter ablation for atrial fibrillation is low (<5%). Complications include pericardial effusion, cardiac tamponade, pulmonary vein stenosis, oesophageal ulceration or perforation, atrio-oesophageal fistula formation, stroke/transient ischaemic attack, phrenic nerve injury, haematoma at the puncture site, and femoral arteriovenous fistula. Among available imaging tools, computed tomography (CT) can be very useful in diagnosing complications of the procedure, particularly in the subacute and delayed stages after ablation. This review illustrates CT imaging of several of the common and uncommon complications of radiofrequency catheter ablation

    Full Text Available Minoxidil is a strong oral vasodilator that is used to treat patients with hypertension refractory to first-line medications. We report a case of minoxidil-associated subacute cardiac tamponade diagnosed by point-of-care ultrasound (POCUS in a hypertensive patient. A 30-year-old male with a past medical history of poorly controlled hypertension (treated with minoxidil and chronic kidney disease presented with 2–3 days of chest pain and shortness of breath with markedly elevated blood pressures. A point-of-care transthoracic echocardiogram revealed a massive pericardial effusion with sonographic tamponade physiology. We review the risk factors for developing pericardial effusions that progress to cardiac tamponade, the utility of diagnosing these patients by POCUS, and the incidence of patients who present with sonographic signs of cardiac tamponade without hypotension.

    We performed thoracoscopic pericardial fenestration for persistent pericardial effusion after radiotherapy for esophageal cancer. An 85-year-old man who had radiation therapy (70.2 Gy) for esophageal cancer was admitted for shortness of breath. Chest computed tomography showed a pericardial effusion. During the 6 months prior to this admission, the patient had undergone percutaneous pericardial drainage 3 times for cardiac tamponade. We performed thoracoscopic partial pericardiectomy with creation of a pleuropericardial window via one access port. Histopathologically, no malignant cells were found in either the resected pericardium or the pericardial effusion. Therefore, we believe the persistent pericardial effusion was secondary to radiotherapy. There was no recurrence of the pericardial effusion for 7 months postoperatively. In summary, thoracoscopic pericardial fenestration is useful in both the diagnosis and treatment of persistent pericardial effusion. (author)

    OBJECTIVE--To investigate the clinical presentation and current management strategies of pericardial effusion in patients with malignancy. DESIGN--Retrospective single centre, consecutive observational study. SETTING--University hospital. PATIENTS--93 consecutive patients with a past or present diagnosis of cancer and a pericardial effusion, including 50 with a pericardial effusion > 1 cm. RESULTS--Of the 50 patients with pericardial effusions > 1 cm, most had stage 4 cancer (64%), were symptomatic at the time of presentation (74%), and had right atrial collapse (74%). Twenty patients were treated conservatively (without pericardiocentesis) and were less symptomatic (55% v 87%, P = 0.012), had smaller pericardial effusions (1.5 (0.4) v 1.8 (0.5), P = 0.02), and less frequent clinical (10% v 40%, P = 0.02) and echocardiographic evidence of tamponade (40% v 97%, P < 0.001) than the 30 patients treated invasively with initial pericardiocentesis (n = 29) or pericardial window placement (n = 1). Pericardial tamponade requiring repeat pericardiocentesis occurred in 18 (62%) of 29 patients after a median of 7 days. In contrast, only four (20%) of 20 patients in the conservative group progressed to frank clinical tamponade and required pericardiocentesis (P = 0.005 v invasive group). The overall median survival was 2 months with a survival rate at 48 months of 26%. Survival, duration of hospital stay, and hospital charges were similar with both strategies. By multivariable analysis, the absence of symptoms was the only independent predictor of long-term survival (relative hazards ratio = 3.2, P = 0.05). Survival was similar in the 43 patients with cancer and pericardial effusions of < or = 1 cm. CONCLUSION--Asymptomatic patients with cancer and pericardial effusion can be managed conservatively with close follow up. In patients with symptoms or clinical cardiac tamponade, pericardiocentesis provides relief of symptoms but does not improve survival and has a high recurrence

    A 69-year-old male was referred to our hospital after being diagnosed as having pericarditis with pericardial effusion. The symptoms of tamponade disappeared after the effusion was drained;although the cause of pericarditis remained unidentified. About 4 months later, the tamponade symptoms recurred due to the thickened nodular pericardium. Partial pericardiectomy was performed, however the patient died on the 52nd day after surgery. Immunohistological examination with calretinin led to the diagnosis of primary malignant pericardial mesothelioma, which was an extremely rare pathology. Because the hyaluronic acid content of the effusion has been reported as a diagnostic aid for malignant mesothelioma, routine examination of the hyaluronic acid content for pericarditis with pericardial effusion may be necessary for early diagnosis and to improve prognosis.

    Background. Neoplastic pericarditis can be presented as acute pericarditis, pericardial effusion, effusive constrictive pericarditis or cardiac tamponade. For the majority of patients, a clinical manifestation of neoplastic pericarditis is absent or remains unrecognised during their life. Case report: A 69-year-old non-smoking woman with acute dyspnoea, tachycardia, jugular venous distension, hepatomegaly and right side pleural effusion was presented in the emergency department. The roentgen picture of the chest confirmed pleural effusion and revealed enlarged heart. An emergency echocardiogram established the diagnosis of cardiac tamponade. The patient improved immediately after the therapeutic pericardiocentesis. Cytology of pericardial fluid confirmed malignant glandular cells, consistent with metastatic adenocarcinoma. A computed chest tomography showed a right side pleural effusion and a solitary round lesion in the right lower lobe of the lung. Bronchoscopy with fundoscopic lung biopsy and brushing revealed adenocarcinoma. Cardiac tamponade as the initial manifestation of malignancy is rare and rare is also malignant pericardial effusion due the adenocarcinoma of the lung in a non-smoking woman. The presented patient had one of the longest survival reported in literature despite a limited life expectancy regardless of the treatment in the patient presented with neoplastic pericarditis.

    The aim of this study was to evaluate the effectiveness of computed tomography (CT) attenuation values in the characterization of pericardial effusion. This study consisted of 96 patients with pericardial effusion who underwent pericardiocentesis. For further diagnostic evaluation of pericardial effusion, all the patients were assessed by thorax CT. CT attenuation values were measured from at least 5 different areas of pericardial fluid by specifying the largest region of interest. The average of these measurements was computed and considered as the CT attenuation value of the patient. The patients were classified into two groups: patients with transudative pericardial effusion and those with exudative pericardial effusion. CT attenuation values were significantly higher in patients with exudative pericardial effusion than in those with transudative pericardial effusion [14.85±10.7 Hounsfield unit (HU) vs. 1.13±4.3 HU, peffusion. In addition, a cut-off value of 6.5 HU had 71.4% sensitivity and 72.3% specificity for the prediction of cardiac tamponade. In patients with pericardial effusion, CT attenuation values seem to be correlated with the characterization parameters of the fluid and may distinguish exudative pericardial effusion from transudative pericardial effusion. This parameter was also found to be a predictor of cardiac tamponade. CT attenuation values can be a useful tool in the clinical evaluation of patients with pericardial effusion.

    At present the most frequent cause of cardiac tamponade is neoplasma. A case of a 32-year-old male with recurrent cardiac tamponade caused by pericardium mesothelioma is described. Despite advanced neoplastic process in the pericardium, pleura and mediastinum, neither radiological examinations of the chest, echocardiography, nor repeated cytological examination of the pericardial exudate, could establish the etiology of the tamponade. Only after a pericardial window had been performed was it possible to: 1) establish the diagnosis and introduce causal treatment; 2) prevent recurrence of the tamponade; 3) perform cytoreduction of the tumor. It seems that in cases of chronic exudative pericarditis of unknown cause it is proper to perform an early pericardial window as a diagnostic and therapeutic procedure. (author) 24 refs, 1 tab

However, pericardial including extra- pulmonary disease, can cause fatal complications. A 37 years old man , without pathological history , who consults for emergency mid-thoracic pain associated with dyspnea, preceded by 10 days before a febrile syndrome with night sweats. Clinical examination showed patient in poor general condition, dyspneic and tachycardia. Cardiovascular examination showed spontaneous jugular veins and painful hepatomegaly, auscultation showed muted heart sounds without pericardial friction and breathless. Chest radiography showed cardiomegaly with symmetric edge straightness, electrocardiogram showed sinus tachycardia at 125bpm, microvoltage and electric alternating QRS complexes. A diffuse ST elevation ascending .Diagnosis of tamponade is suspected, transthoracic echocardiography showed abundance circumferential pericardial effusion measuring 40mm, with prolonged collapse of the right atrium and right ventricle , paradoxical septum , and significant changes in the flow inspiration. Pericardiocentesis ultrasound-guided has allowed a gradual evacuation of 2 liters of a cloudy yellow pericardial fluid, slightly viscous. Direct examination revealed the presence of 14 400 white cells, 99 % are neutrophils with gram-negative bacilli.

    Background Pericardial effusion is still a common postoperative complication after open heart surgery with cardiopulmonary bypass. Pericardial effusion significantly prolongs the hospital stay and associated costs as well as affecting overall outcomes after open heart surgery in Hanoi Heart Hospital, a tertiary hospital in Vietnam with an annual volume of 1000 patients. This study aimed to investigate the clinical presentation, incidence, and risk factors of postoperative pericardial effusion, which may ensure better prevention of pericardial effusion and improvement in surgical outcomes after open heart surgery. Methods A cross-sectional study was performed on 1127 patients undergoing open heart surgery from January 2015 to December 2015. Results Thirty-six (3.19%) patients developed pericardial effusion. Of these, 16 (44.4%) had cardiac tamponade. Pericardial effusion occurred after valve procedures in 77.8% of cases. Pericardial effusion was detected after discharge in 47.2% of cases at a mean time of 18.1 ± 13.7 days. Univariate logistic regression analysis showed that age > 25 years, body surface area ≥ 1.28 m 2 , preoperative liver dysfunction, New York Heart Association class III/IV, left ventricular end-diastolic diameter z score ≥ 0.55, and postoperative anticoagulant use were associated with postoperative pericardial effusion. Multivariate logistic regression analysis showed that left ventricular end-diastolic diameter z score ≥ 0.55 was an independent risk factor for postoperative pericardial effusion. Conclusions Routine postoperative echocardiography is necessary to detect postoperative pericardial effusion. Increased left ventricular end-diastolic dimension is an independent predictor of postoperative pericardial effusion.

    Full Text Available Abstract Introduction Chronic lymphocytic leukemia is an indolent disease that often presents with complaints of lymphadenopathy or is detected as an incidental laboratory finding. It is rarely considered in the differential diagnosis of patients presenting with tamponade or a large, bloody pericardial effusion. In patients without known cancer, a large, bloody pericardial effusion raises the possibility of tuberculosis, particularly in patients from endemic areas. However, the signs, symptoms and laboratory findings of pericarditis related to chronic lymphocytic leukemia can mimic tuberculosis. Case Presentation We report the case of a 58-year-old African American-Nigerian woman with a history of travel to Nigeria and a positive tuberculin skin test who presented with cardiac tamponade. She had a mild fever, lymphocytosis and a bloody pericardial effusion, but cultures and stains were negative for acid-fast bacteria. Assessment of blood by flow cytometry and pericardial biopsy by immunohistochemistry revealed CD5 (+ and CD20 (+ lymphocytes in both tissues, demonstrating this to be an unusual manifestation of early stage chronic lymphocytic leukemia. Conclusion Although most malignancies that involve the pericardium clinically manifest elsewhere before presenting with tamponade, this case illustrates the potential for early stage chronic lymphocytic leukemia to present as a large pericardial effusion with tamponade. Moreover, the presentation mimicked tuberculosis. This case also demonstrates that it is possible to treat chronic lymphocytic leukemia-related pericardial tamponade by removal of the fluid without chemotherapy.

    Prompt recognition of the signs and symptoms of pericardial disease is critical so that appropriate treatments can be initiated. Acute pericarditis has a classical presentation, including symptoms, physical examination findings, and electrocardiography abnormalities. Early recognition of acute pericarditis will avoid unnecessary invasive testing and prompt therapies that provide rapid symptom relief. Non-steroidal anti-inflammatory drugs (NSAIDs) remain first-line therapy for uncomplicated acute pericarditis, although colchicine can be used concomitantly with NSAIDS as the first-line approach, particularly in severely symptomatic cases. Colchicine should be used in all refractory cases and as initial therapy in all recurrences. Aspirin should replace NSAIDS in pericarditis complicating acute myocardial infarction. Systemic corticosteroids can be used in refractory cases or in those with immune-mediated etiologies, although generally should be avoided due to a higher risk of recurrence. Pericardial effusions have many etiologies and the approach to diagnosis and therapy depends on clinical presentation. Pericardial tamponade is a life-threatening clinical diagnosis made on physical examination and supported by characteristic findings on diagnostic testing. Prompt diagnosis and management is critical. Treatment consists of urgent pericardial fluid drainage with a pericardial drain left in place for several days to help prevent acute recurrence. Analysis of pericardial fluid should be performed in all cases as it may provide clues to etiology. Consultation of cardiac surgery for pericardial window should be considered in recurrent cases and may be the first-line approach to malignant effusions, although acute relief of hemodynamic compromise must not be delayed. Constrictive pericarditis is associated with symptoms that mimic many other cardiac conditions. Thus, correct diagnosis is critical and involves identification of pericardial thickening or calcification in

    Background. The diagnosis and treatment of massive pericardial effusion and cardiac tamponade have evolved over the years with a tendency towards a more comprehensive diagnostic workup and less traumatic intervention. Method. We reviewed and analysed the data of 32 consecutive patients who underwent surgery on account of massive pericardial effusion and cardiac tamponade in a semiurban university hospital in Nigeria from February 2010 to February 2016. Results. The majority of patients (34.4%) were between 31 and 40 years. Fourteen patients (43.8%) presented with clinical and echocardiographic feature of cardiac tamponade. The majority of patients (59.4%) presented with haemorrhagic pericardial effusion and the average volume of fluid drained intraoperatively was 846 mL  ± 67 mL. Pericardium was thickened in 50% of cases. Subxiphoid pericardiostomy was performed under local anaesthesia in 28 cases. No postoperative recurrence was observed; however 5 patients developed features of constrictive pericarditis. The relationship between pericardial thickness and development of pericardial constriction was statistically significant (p = 0.004). Conclusion. Subxiphoid pericardiostomy is a very effective way of treating massive pericardial effusion. Removing tube after adequate drainage (50 mL/day) and treatment of primary pathology are key to preventing recurrence. There is also a need to follow up patients to detect pericardial constriction especially those with thickened pericardium. PMID:27517082

    A large pleural effusion causing cardiac tamponade physiology and severe hemodynamic compromise is an uncommon event. We report a case of a 53-year-old woman with severe hypothyroidism presenting with myxedema coma and refractory shock. Her hemodynamic status failed to respond to fluid resuscitation and vasopressors. A transthoracic echocardiogram and chest radiograph demonstrated a pericardial fluid accumulation associated with a large left-sided pleural effusion. Thoracostomy tube insertion resulted in prompt improvement of the patient's hemodynamic status. Our finding demonstrates that a large pleural effusion may play an important role in cardiac tamponade physiology.

    Full Text Available Pericardial disorders constitute a relatively common cause of heart disease. Although acute pericarditis, especially the idiopathic forms that are the most prevalent, is considered a benign disease overall, its short- and long-term complications, namely, recurrent pericarditis, cardiac tamponade and constrictive pericarditis, constitute a matter of concern in the medical community. In recent years, several clinical trials contributed to redefining our traditional approach to pericardial diseases. In this review, we provide the most recent evidence concerning diagnosis, treatment modalities and short- and long-term prognosis of the most common pericardial disorders.

    Conclusion: A prompt diagnosis using FAST and treatment can be lifesaving in traumatic acute cardiac tamponade. A pericardiotomy via a thoracotomy is mandatory for lifesaving cardiac decompression in acute traumatic cardiac tamponade in cases of ineffective drainage due to clot formation within the pericardial space.

  17. Pericardial Effusion due to Primary Malignant Pericardial Mesothelioma: A Common Finding but an Uncommon Cause

    Full Text Available This case report describes a 37-year-old female who was admitted to our Emergency Department because of shortness of breath. On physical examination, she had dyspnea and tachycardia and blood pressure was 80/50 mmHg with a pulsus paradoxus of 22 mmHg. Neck veins were distended, heart sounds were distant, and dullness was found on both lung bases. Her chest X-ray revealed bilateral pleural effusion and cardiomegaly. On both computed tomography and echocardiography the heart was of normal size and a large pericardial effusion was noted. The echocardiogram showed signs of impending tamponade, so the patient underwent an emergent pericardiocentesis. No infectious etiology was found and she was assumed to have viral pericarditis and was treated accordingly. However, when the pericardial effusion recurred and empirical therapy for tuberculosis failed, a pericardial window was performed. A typical staining pattern for mesothelioma was found on her pericardial biopsy specimen. Since no other mesodermal tissue was affected, a diagnosis of primary malignant pericardial mesothelioma was made. Chemotherapy was not effective and she passed away a year after the diagnosis was made. This case highlights the difficulties in diagnosing this uncommon disease in patients that present with the common finding of pericardial effusion.

    A 53-year-old male admitted with increased shortness of breath. In the physical examination, he had dyspnea, tachycardia and tachypnea. An echocardiogram showed large pericardial effusion (PE) as well as significant pulmonary hypertension. He had been started recently on minoxidil for blood pressure control. PE was reported to occur with minoxidil treatment both in patients undergoing dialysis and those with normal renal function. Pulmonary hypertension has been reported to affect the cardiac tamponade physiology. Because of significant pulmonary hypertension in our patient, a right heart catheterization was also done, which prevented cardiac tamponade. He was treated conservatively without any intervention, and PE resolved spontaneously after discontinuation of minoxidil.

    Both MRI, CT and sonography will give a good presentation of fluid collection in pleura and pericardium. Sonography is the ideal imaging method for monitoring interventional procedures. Its ability to visualize superficial fluid collection and its real-time capability allows precise control of needle and catheter insertions. If the abnormality is poorly seen with ultrasound, often because of air in the collection, CT can be used as a guidance system. Diagnostic thoracocentesis and pericardiocentesis are performed mainly to exclude malignancy and infections, and the punctions are made with small needles. Therapeutic thoracocentesis is usually performed to relieve dyspnoe and small catheters are used. Drainage of empyema is performed with larger catheters because of the high viscosity of the infected fluid. Patients with threatening cardiac tamponade will often respond immediately to drainage of the pericardial space by catheter. These procedures can be done with local anesthesia only. If complications occur, it is mainly the pneumothorax that has to be treated. This can be managed directly under the procedure as the drainage catheter is attached to continuous pleural suction, or a catheter can be inserted in the pleural space after diagnostic punction. Patients with coagulation abnormalities must be evaluated especially before any intervention, otherwise there are no contraindications for these image-guided percutaneous procedures. 14 refs., 6 figs.

    BACKGROUND Cardiac tamponade caused by pericardial effusion has a high mortality rate; thus, it is important to diagnose and treat this condition immediately. Specifically, bacterial pericarditis, although now very rare, is often fatal because of its fulminant process. CASE REPORT We present a case of a 61-year-old man with metastatic small cell lung cancer undergoing chemotherapy who presented with fatigue, poor appetite, and altered mental status. He was found to have a large-volume pericardial effusion with tamponade physiology. He underwent emergent pericardiocentesis. The pericardial effusion was nonmalignant, with cultures growing Streptococcus pneumoniae. It was only after his emergent pericardiocentesis that previous imaging from one month prior was able to be reviewed, which showed possible right upper lobe abscess. CONCLUSIONS Most pericardial effusions in cancer patients are related to their malignancy, either due to direct metastasis or secondary physiologic effects. This case is a unique example of a lung cancer patient presenting with a pneumococcal pericardial effusion, which in itself is a rare phenomenon. This case report demonstrates the importance of considering early antibiotic therapy in patients presenting with pericardial effusion, especially given the high mortality rates of infectious pericardial effusions.

    A 12-year-old boy with massive pericardial effusion which developed 7 years after radiotherapy was reported. In May 1986, he had stage I Hodgkin's disease of the right axillary lymph nodes. He received 40 Gy mantle field radiotherapy without chemotherapy following complete resection of the tumor. Seven years later, he was admitted with symptoms of dyspnea and facial edema. Chest X-ray films showed pleural effusion and echocardiography showed cardiac tamponade. Cytologic examinations of the pleural and pericardial effusion, computed tomography of chest, and gallium scintigraphy showed no signs of malignancy. He was diagnosed as suffering from acute pericarditis and cardiac tamponade, most likely due to radiotherapy. Following initial improvement by pericardiocentesis, dyspnea reappeared with an increase in pericardial effusion. The effusion subsided in response to prednisolone following the second pericadiocentesis. Although pericarditis following radiotherapy is rarely reported in Japan, partly because of the low incidence of Hodgkin's disease, it should be emphasized as a major sequela of radiotherapy.

    Thirty-three patients with pericardial effusion after open heart surgery were investigated with computed tomography (CT). Twelve of the 33 patients also underwent echocardiography prior to pericardiocentesis. The effusions were typed according to the results of the CT investigation. Because of postoperative adhesions, typical patterns of localized pericardial effusions were found in 16 patients. The localized compartments were seen on the right and left side of the heart and around the aorta and the pulmonary artery. CT was therefore shown to be of value for selecting the approach for drainage with catheter pericardiocentesis. (orig.)

    An 87-year-old woman was diagnosed with third-degree atrioventricular block and underwent pacemaker implantation. On postoperative day 12, she experienced cardiac tamponade that was suspected on computed tomography to be caused by lead perforation; therefore, we performed open-heart surgery. However, we could not identify a perforation site on the heart, and drained a 400-mL exudative pericardial effusion. Subsequently, we diagnosed the pericardial effusion as due to pericarditis induced by pacemaker implantation. It is sometimes difficult to distinguish pericarditis from pacemaker lead perforation, so both should be included in the differential diagnosis. © The Author(s) 2014.

    Full Text Available Aspergillus pericarditis is a rare and life-threatening infection in immunosuppressed patients. It has nonspecific clinical manifestations that often mimic other disease entities especially in patients who have extensive comorbidities. Diagnosis is oftentimes delayed and rarely done antemortem. A high degree of suspicion in immunocompromised patients is necessary for evaluation and timely diagnosis. This is a case of Aspergillus pericarditis with cardiac tamponade in a renal transplant patient with liver cirrhosis. Two months after transplant, he developed decompensation of his cirrhosis from hepatitis C, acute cellular rejection, and Kluyvera bacteremia, followed by vancomycin-resistant Enterococcus faecium (VRE bacteremia. Four months after transplant, the patient presented with lethargy and fluid overload. He subsequently developed shock and ventilator-dependent respiratory failure. An echocardiogram showed pericardial effusion with cardiac tamponade. He had emergent pericardiocentesis that showed purulent drainage. He was started on broad-spectrum antibiotics. Amphotericin B was initiated when the pericardial fluid grew mold that was later identified as Aspergillus fumigatus. The patient quickly decompensated and expired.

    Persistent bleeding into the pericardial space in the early hours after cardiac operation not uncommonly results in cardiac tamponade. Single chamber tamponade also might be expected, since in this setting the pericardium frequently contains firm blood clots localized to the area of active bleeding. However, this complication has received very little attention in the surgical literature. We are therefore providing documentation that isolated right atrial tamponade can occur as a complication of cardiac operation and that there exists a potential for misdiagnosis and hence incorrect treatment of this condition. Right atrial tamponade may be recognized by a combination of low cardiac output, low blood pressure, prominent neck veins, right atrial pressure in excess of pulmonary capillary wedge pressure and right ventricular end-diastolic pressure, and a poor response to plasma volume expansion. Findings on chest roentgenogram and gated wall motion scintigraphy may be highly suggestive. This review should serve to increase awareness of this complication and to provide some helpful diagnostic clues

    Eosinophilic granulomatosis with polyangiitis (EGPA), which was previously called Churg-Strauss syndrome, is a necrotizing systemic vasculitis of unknown cause accompanied by prominent eosinophilia. Cardiovascular complications, including eosinophilic myocarditis, are a major cause of mortality in this disorder. Acute pericarditis with slight pericardial effusion is a typical manifestation in EGPA, though hemodynamically significant pericardial effusion has been reported in a few cases. We report a case that initially presented with isolated cardiac tamponade, which was followed by systemic manifestations of EGPA over 3 weeks. Including the present case, previous EGPA cases with cardiac tamponade are reviewed to delineate its clinical characteristics.

    Full Text Available Abstract Introduction Mediastinal schwannomas are typically benign and asymptomatic, and generally present no immediate risks. We encountered a rare case of a giant benign posterior mediastinal schwannoma, complicated by life-threatening cardiac tamponade. Case presentation We report the case of a 72-year-old Japanese woman, who presented with cardiogenic shock. Computed tomography of the chest revealed a posterior mediastinal mass 150 cm in diameter, with pericardial effusion. The cardiac tamponade was treated with prompt pericardial fluid drainage. A biopsy was taken from the mass, and after histological examination, it was diagnosed as a benign schwannoma, a well-encapsulated non-infiltrating tumor, originating from the intrathoracic vagus nerve. It was successfully excised, restoring normal cardiac function. Conclusion Our case suggests that giant mediastinal schwannomas, although generally benign and asymptomatic, should be excised upon discovery to prevent the development of life-threatening cardiopulmonary complications.

    Full Text Available Transesophageal echocardiography (TEE is a valuable tool for evaluating hemodynamic instability in patients under general anesthesia. We present the case of a 28-year-old man who presented with complaints of testicular pain concerning for testicular torsion. After induction of general anesthesia for scrotal exploration and possible orchiopexy, the patient developed severe and persistent hypotension. Using intraoperative TEE, the diagnosis of pericardial tamponade was made, and an emergent pericardial window was performed.

  11. Catheter ablation of epicardial ventricular tachycardia

    Full Text Available Ventricular tachycardias (VTs can usually be treated by endocardial catheter ablation. However, some VTs can arise from the epicardial surface, and their substrate can be altered only by epicardial catheter ablation. There are two approaches to epicardial catheter ablation: transvenous and transthoracic. The transvenous approach through the coronary venous system (CVS has been commonly used because it is easily accessible. However, this approach may be limited by the distribution of the CVS and insufficient radiofrequency energy delivery. Transthoracic epicardial catheter ablation has been developed to overcome these limitations of the transvenous approach. It is a useful supplemental or even preferred strategy to eliminate epicardial VTs in the electrophysiology laboratory. This technique has been applied for scar-related VTs secondary to often non-ischemic cardiomyopathy and sometimes ischemic cardiomyopathy, and idiopathic VTs as the epicardial substrates of these VTs have become increasingly recognized. When endocardial ablation and epicardial ablation through the CVS are unsuccessful, transthoracic epicardial ablation should be the next option. Intrapericardial access is usually obtained through a subxiphoidal pericardial puncture. This approach might not be possible in patients with pericardial adhesions caused by prior cardiac surgery or pericarditis. In such cases, a hybrid procedure involving surgical access with a subxiphoid pericardial window and a limited anterior or lateral thoracotomy might be a feasible and safe method of performing an epicardial catheter ablation in the electrophysiology laboratory. Potential complications associated with this technique include bleeding and collateral damage to the coronary arteries and phrenic nerve. Although the risk of these complications is low, electrophysiologists who attempt epicardial catheter ablation should know the complications associated with this technique, how to minimize their

    A pericardial effusion (PE) is a relatively common finding in clinical practice. It may be either isolated or associated with pericarditis with or without an underlying disease. The aetiology is varied and may be either infectious (especially tuberculosis as the most common cause in developing countries) or non-infectious (cancer, systemic inflammatory diseases). The management is essentially guided by the hemodynamic effect (presence or absence of cardiac tamponade), the presence of concomitant pericarditis or underlying disease, and its size and duration. The present paper reviews the current knowledge on the aetiology, classification, diagnosis, management, therapy, and prognosis of PE in clinical practice.

    Full Text Available Tuberculosis accounts for up to 4% of acute pericarditis and 7% cases of cardiac tamponade. Prompt treatment can be life saving but requires accurate diagnosis. We report a case of 30-year-old male who presented with fever, chills, and dry nonproductive cough since one month. The case was diagnosed by radiological findings, which were suggestive of pulmonary tuberculosis, followed by acid fast staining and culture of the aspirated pericardial fluid. The patient was responding to antitubercular treatment at the last follow up.

    Retinal detachment (RD) with proliferative vitreoretinopathy (PVR) often requires surgery. During surgery, a tamponade agent is needed to reduce the rate of recurrent retinal detachment. The objective of this review was to evaluate the benefits and adverse outcomes of surgery with various tamponade agents. We searched the Cochrane Controlled Register (CENTRAL), MEDLINE, EMBASE, Latin America and Carribbean Health Sciences (LILACS) and the UK Clinical Trials Gateway (UKCTG). There were no language or date restrictions in the search for trials. The electronic databases were last searched on 9 July 2009. We included randomized clinical trials comparing patients treated with various tamponade agents. Two individuals screened the search results independently. One study with two trials was eligible for inclusion in the review. One study with two trials was included in the review. The first trial randomized 151 eyes to receive either silicone oil or sulfur hexafluoride (SF(6)) gas tamponades; the second trial randomized 271 eyes to receive either silicone oil or perfluropropane (C(3)F(8)) gas tamponades. In patients with RD associated with PVR, pars plana vitrectomy and infusion of either silicone oil or perfluropropane gas appear comparable for a broad variety of cases. Sulfur hexafluoride gas was associated with worse anatomic and visual outcomes than either silicone oil or perfluropropane gas. The use of either C(3)F(8) or silicone oil appears reasonable for most patients with RD associated with PVR. Because there do not appear to be any major differences in outcomes between the two agents, the choice of a tamponade agent should be individualized for each patient.

    Cardiac tamponade is a medical emergency condition. Rapid diagnosis and determination of the etiology with epidemiologic consideration may lead to earlier treatment and improved survival. Occasionally, the etiology may be clearly related to a recognized underlying disease, but the possibility of unrelated etiologies should be considered. Pericarditis tuberculosis, a rare manifestation of extrapulmonary tuberculosis in a non-HIV patient, has to be deliberate as one of the etiology, especially in the endemic area. Here, we report a case of 28 years old male with β thalassemia major presented with excessive exertion breathlessness progressing to orthopnea. Sign of cardiac tamponade was identified from echocardiography which showed large pericardial effusion with swinging heart and right atrial systolic collapse. Pericardiocentesis was performed immediately, drained 870 ml of hemorrhagic fluid from inserted pigtail. The patient was treated with the anti-tuberculosis regimen and oral corticosteroid after real-time polymerase chain reaction of Mycobacterium tuberculosis positivity in pericardial fluid. MRI T2 confirmed no haemosiderosis in patient’s heart. After treatment, the patient responded well and showed clinical improvement.

    Silent cerebral lesions with the multielectrode-phased radiofrequency (RF) pulmonary vein ablation catheter (PVAC(®)) have recently been investigated. However, comparative data on safety in relation to irrigated RF ablation are missing. One hundred and fifty consecutive patients (58 ± 12 years, 56 female) underwent first pulmonary vein isolation (PVI) for atrial fibrillation (61% paroxysmal) using PVAC(®) (PVAC). Procedure data as well as in-hospital complications were compared with 300 matched patients who underwent PVI using irrigated RF (iRF). Procedure duration (148 ± 63 vs. 208 ± 70 min; P drainage n = 0 vs. n = 6] occurred more frequently using iRF. Two patients in each group developed a TIA (1.3% vs. 0.6%). Of note, four of five thromboembolic events in the PVAC group (two TIAs and three transient ST elevations during ablation) occurred when all 10 electrodes were used for ablation. Pulmonary vein isolation using PVAC as a 'one-shot-system' has a comparable complication rate but a different risk profile. Pericardial effusion and tamponade occurred more frequently using iRF, whereas thromboembolic events were more prevalent using PVAC. Occurrence of clinically relevant thromboembolic events might be reduced by avoidance of electrode 1 and 10 interaction and uninterrupted anticoagulation, whereas contact force sensing for iRF might minimize pericardial effusion.

    Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patient was treated with L-thyroxine at 0.15 mg daily. However, during admission, he developed symptoms of cardiac tamponade. Closed pericardiostomy was performed, after which the patient's chest discomfort improved, and his vital signs stabilized. Herein, we report a case of an adolescent with Noonan syndrome, who was diagnosed with Hashimoto thyroiditis with an unusual presentation of cardiac tamponade.

    Full Text Available Primary mesothelioma of the pericardium is a rare heart tumor with a difficult diagnosis, revealed in vivo in less than a quarter of cases. The disease occurs at any age, more common in men and variably exhibits a broad spectrum of non-specific symptoms of congestive heart failure, constrictive pericarditis, pericardial effusion or cardiac tamponade. Patients are usually observed with peripheral edema, ascites, dyspnea, cough, chest pain and atrial fibrillation. Such symptoms, in the absence of cancer alertness, are erroneously attributed by doctors to more common cardiovascular diseases. As a result, primary mesothelioma is detected in 75-90% of cases only at necropsy. The article describes a case of detection at autopsy of primary pericardial mesothelioma sarcomatous type with invasion into the myocardium in a patient of 74 years old. The patient also suffered from concomitant coronary artery disease with a long history of chronic heart failure and recurrent pulmonary embolism, associated with deep vein thrombosis at the final stage of the disease. An objective study revealed signs of chronic heart failure. The laboratory data included mild iron deficiency anemia, insignificant leukocytosis and leukocyturia, as well as signs of moderate chronic kidney disease. Instrumental results corresponded to long-term course of hypertension, signs of congestive heart failure in the presence of atrial fibrillation, atherosclerosis of lower limbs arteries in patient with abdominal obesity. Thus, there were no clinical signs of pericardial damage in a standard examination of the patient. The article describes the complexity of the disease diagnosis, variable clinical picture, as well as the diagnostic value of various instrumental methods from the perspective of evidence-based medicine. It is noted that clinical alertness is still the most important factor in the lifetime diagnosis of pericardial mesothelioma. Disease should be considered in patients with

    On September 10, 1898, Empress Elizabeth of Austria, known as Sissi, was stabbed with a stiletto knife in her chest by an Italian anarchist in Geneva, Switzerland, and died 1 hour later. The autopsy revealed a large clot in the pericardial sac due to a perforation of the left ventricular wall, and the report concluded, "Death was undoubtedly caused by a progressive and slow blood leak, sufficient to compress the heart and to suspend its functions." Since antiquity, wounds of the heart had been considered immediately fatal, until Paré observed a delayed death after a stab to the heart in the 16th century. The physiology of cardiac tamponade was then elucidated by Richard Lower in 1669. However, it was only in the 19th century that the main clinical features of cardiac tamponade were described and the first treatments attempted. Kussmaul identified its most important clinical hallmark, pulsus paradoxus, in 1873 and the term "tamponade of the heart" was coined for the first time by Rose in 1884. Romero and Larrey pioneered the open drainage of the pericardium early in the century, and Rehn performed the first successful surgical suture of a heart wound in 1896. In conclusion, logistics aside, medical knowledge at the end of the 19th century would have been theoretically sufficient to save the empress from death.

    Full Text Available An 84-year-old man with hypertension and a history of deep venous thrombosis (on warfarin was admitted with shortness of breath presumed to be due to congestive heart failure. Echocardiogram performed the following day showed a low-normal ejection fraction with signs of elevated right-sided pressures but was otherwise normal. He improved with diuretic therapy but after a few days was found to be hypotensive with a concomitant rise in creatinine with decreased urine output. This was felt to be secondary to over-diuresis but he did not respond to small boluses of intravenous fluids as his kidney function continued to worsen and hypotension persisted. He was transferred to the intermediate care unit where a rapid, bedside ultrasound revealed a new, moderate-sized pericardial effusion with tamponade physiology. Pericardiocentesis, with removal of 750 cc of frank blood, led to dramatic improvement in blood pressure, kidney function, and urine output. Here, we demonstrate the utility of point-of-care ultrasound in a community hospital setting where urgent echocardiogram is not routinely available. We also report acute kidney injury due to pericardial tamponade reversed with therapeutic pericardiocentesis.

    We report surgical management of radiation-induced massive pericardial effusion. A 55-year-old man undergoing definitive chemoradiotherapy (CRT) for esophageal squamous cell carcinoma in the middle thorax was treated with megavoltage equipment using anterior-posterior opposed fields up to 45 Gy, including the primary tumor and regional lymphnodes. A booster dose of 25 Gy was given to the primary tumor for a total dose of 70 Gy, using bilateral oblique fields. Three years and 6 months later, he was treated with an additional 30 Gy for mediastinal lymphnode metastasis, followed by percutaneous pericardiocentesis for cardiac tamponade with massive pericardial effusion 4 times in 5 months. Because medical intervention was inadequate, he underwent pericardial effusion via video-assisted thoracoscopic pericardial window placement 4 years and 6 months after definitive CRT. Histopathological examination of the pericardial tissue specimen showed marked fibrosis but no cancer recurrence, compatible with radiation pericarditis. The postoperative course was uneventful, and pericardial effusion completely disappeared. (author)

    The reliability of dynamic and volumetric variables of fluid responsiveness in the presence of pericardial effusion is still elusive. The aim of the present study was to investigate their predictive power in a porcine model with hemodynamic relevant pericardial effusion. A single-center animal investigation. Twelve German domestic pigs. Pigs were studied before and during pericardial effusion. Instrumentation included a pulmonary artery catheter and a transpulmonary thermodilution catheter in the femoral artery. Hemodynamic variables like cardiac output (COPAC) and stroke volume (SVPAC) derived from pulmonary artery catheter, global end-diastolic volume (GEDV), stroke volume variation (SVV), and pulse-pressure variation (PPV) were obtained. At baseline, SVV, PPV, GEDV, COPAC, and SVPAC reliably predicted fluid responsiveness (area under the curve 0.81 [p = 0.02], 0.82 [p = 0.02], 0.74 [p = 0.07], 0.74 [p = 0.07], 0.82 [p = 0.02]). After establishment of pericardial effusion the predictive power of dynamic variables was impaired and only COPAC and SVPAC and GEDV allowed significant prediction of fluid responsiveness (area under the curve 0.77 [p = 0.04], 0.76 [p = 0.05], 0.83 [p = 0.01]) with clinically relevant changes in threshold values. In this porcine model, hemodynamic relevant pericardial effusion abolished the ability of dynamic variables to predict fluid responsiveness. COPAC, SVPAC, and GEDV enabled prediction, but their threshold values were significantly changed. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The aims of this study were to analyze the predictive factors for the use of intrauterine balloon insertion and to evaluate the efficacy and factors affecting failure of uterine tamponade with a Bakri balloon during cesarean section for abnormal placentation.We reviewed the medical records of 137 patients who underwent elective cesarean section for placenta previa between July 2009 and March 2014. Cesarean section and Bakri balloon insertion were performed by a single qualified surgeon. The Bakri balloon was applied when blood loss during cesarean delivery exceeded 1,000 mL.Sixty-four patients (46.7% required uterine balloon tamponade during cesarean section due to postpartum bleeding from the lower uterine segment, of whom 50 (78.1% had placenta previa totalis. The overall success rate was 75% (48/64 for placenta previa patients. Previous cesarean section history, anterior placenta, peripartum platelet count, and disseminated intravascular coagulopathy all significantly differed according to balloon success or failure (all p<0.05. The drainage amount over 1 hour was 500 mL (20-1200 mL in the balloon failure group and 60 mL (5-500 mL in the balloon success group (p<0.01.Intrauterine tamponade with a Bakri balloon is an adequate adjunct management for postpartum hemorrhage following cesarean section for placenta previa to preserve the uterus. This method is simple to apply, non-invasive, and inexpensive. However, possible factors related to failure of Bakri balloon tamponade for placenta previa patients such as prior cesarean section history, anterior placentation, thrombocytopenia, presence of DIC at the time of catheter insertion, and catheter drainage volume more than 500 mL within 1 hour of catheter placement should be recognized, and the next-line management should be prepared in advance.

    Pericardial or mediastinal hemorrhage requiring reoperation occurs in 2% to 5% of patients, usually early (0 to 48 hours), after open-heart surgery. This hemorrhage may be occult, and resulting cardiac tamponade may easily be misinterpreted as ventricular dysfunction, common early postoperatively. In such cases, appropriate and timely intervention may not occur. Of 50 patients evaluated by technetium-99m red blood cell gated equilibrium radionuclide ventriculography (RNV) because of early postoperative cardiogenic shock of uncertain etiology, 17 had unique scintigraphic images suggestive of intrathoracic hemorrhage. Of these 17, 5 had a generalized halo of abnormal radioactivity surrounding small hyperdynamic right and left ventricles, 11 had localized regions of intense blood pool activity outside the cardiac chambers (two with compression of single chambers), and one demonstrated marked radionuclide activity in the right hemithorax (2000 ml of blood at reoperation). Twelve patients had exploratory reoperation for control of hemorrhage as a direct result of the scintigraphic findings, three were successfully treated with fresh frozen plasma and platelet infusions along with medical interventions to optimize cardiac performance, and two patients died in cardiogenic shock (presumed tamponade) without reoperation. In the 12 reoperated patients, all were confirmed to have active pericardial bleeding. Scintigraphic localization of abnormal blood pools within the pericardium corresponded to the sites at which active bleeding was witnessed at reoperation. The abnormal bleeding was etiologically related to the tamponade state, with marked improvement in hemodynamics after reoperation. Nine additional patients were reoperated for presumed tamponade after RNV revealed an exaggerated halo of photon deficiency surrounding the cardiac chambers

    Conventionally postpartum hemorrhage (PPH) has been defined as blood loss of more than 500 ml following vaginal delivery and 1000 ml following a cesarean section [Pritchard et al. in Am J Obstet Gynecol 84(10):1271-1282, (1962)]. Another definition labels PPH as any blood loss which causes a 10 % drop in hematocrit [Combs et al. in Obstet Gynecol 77:69-76, (1991)] or which threatens the hemodynamic stability of the patient and necessitates blood transfusion [Prendiville et al. in Cochrane Database Syst Rev 2:CD000007, (2000)]. The purpose of this study was to evaluate the effectiveness of condom tamponade in the management of massive obstetric hemorrhage. To evaluate the efficacy of a condom as a tamponade for intrauterine pressure to stop massive PPH. This prospective study was done in the Obstetrics and Gynecology Department of NIMS Medical College and Hospital, Jaipur, between December 2013 and February 2015. With aseptic precautions, a sterile rubber catheter fitted with a condom was introduced into the uterus. The condom was inflated with 250-500 ml normal saline according to need. Vaginal bleeding was observed, and further inflation was stopped when bleeding ceased. In all but 2 (94.44 %) the cases, postpartum bleeding was stopped within 10 min of creation of tamponade. On an average, 350 ml of normal saline was required to create adequate tamponade to stop the bleeding. Use of condom tamponade can effectively help in reducing both maternal morbidity and mortality associated with PPH. Our study encourages use of condom tamponade which is efficient, cost-effective, easily available and requires lesser skills as compared to the traditional surgical procedures.

    A 53-year-old woman was diagnosed with hypopituitarism following an acute presentation with cardiac tamponade and hyponatraemia, having recently been investigated for a pericardial effusion. Secondary hypothyroidism is a rare cause of pericardial effusion and tamponade, but an important differential to consider. Management requires appropriate hormone replacement and, critically, a low threshold for commencing stress dose steroids. Clinical signs classically associated with cardiac tamponade are frequently absent in cases of tamponade due to primary and secondary hypothyroidism, and the relatively volume deplete state of secondary hypoadrenalism in hypopituitarism may further mask an evolving tamponade, as the rise in right atrial pressure is less marked even in the presence of large effusion. Our case demonstrates the importance of a high index of suspicion for cardiac tamponade in this patient cohort, even in the absence of clinical signs, and for measuring both thyroid-stimulating hormone and thyroxine levels when evaluating a pericardial effusion. © Royal College of Physicians 2017.

    AIM: To study the image morphology on computed tomography (CT) and magnetic resonance imaging (MRI) of pericardial abscess, an uncommon complication of tuberculous pericarditis. MATERIAL AND METHODS: In a 9-year period, 120 patients with clinical and imaging features of constrictive pericarditis were retrospectively reviewed. Of them, 13 patients (age range, 1-51 years; seven females, six males), who had a pericardial mass on echocardiography, and were subjected to CT (11 patients) and MRI (7 patients), were included as subjects of the present study. Five patients underwent both the investigations. The intra-lesional morphology, location, extent, mass effect on adjacent cardiac chambers, secondary effects on the atria and venae cavae, and pericardial thickness were studied. Histopathological confirmation of tubercular infection was available in nine patients. In the remaining four patients, the diagnosis was based on typical extra-cardiac manifestations of tuberculosis. RESULTS: A total of 15 abscesses were detected. CT showed a lesion with a hypodense core and an enhancing rim in all patients. On spin-echo T1-weighted MRI, 57% of the paients had a lesion with a hyperintense core, suggesting an exudative process. Seventy-one percent of patients showed a lesion with a hyperintense core on T2-weighted MRI, while one lesion was hypointense. Post-gadolinium MRI was performed in two patients and showed an enhancing rim in both, with enhancing septa in one. The predominant site of involvement was in the right atrioventricular (AV) groove (77%). Localized tamponade, suggested by the presence of mass effect on an adjacent cardiac chamber, was noted in nine (69%) cases, with proximal atrial dilatation in 78% of them. Four other patients (31%) had atrial dilatation without a localized mass effect. CONCLUSION: Pericardial abscess is an uncommon complication of constrictive pericarditis. Tuberculosis was responsible for abscess formation in all cases in this study. The

    The diagnosis of hypothyroidism is difficult because hypothyroidism in adults and especially the elderly, classic, has an insidious onset with a range of nonspecific symptoms which may delay diagnosis for months or even years. Old age seems to represent trigger factor for autoimmune diseases, including hypothyroidism. Clinical features in hypothyroidism, such as weight gain, fatigue, cold intolerance, constipation, dry skin, edema and muscle weakness, and decreased osteo-tendinous reflexes are usually subtle and can be overlooked. Thyroid dysfunction may be associated with a negative impact on the cardiovascular system. Pericardial, pleural and peritoneal effusions are common findings in hypothyroidism. This case report represents a typical primary hypothyroidism (autoimmune) and shows the clinical features of this disease. Basically we talked about a severe myxedema with the involvement of internal organs in an elderly woman and the euthyroidism restoration, under thyroid replacement therapy, was correlated with the clinical improvement and cardiovascular and neurological status, with radiographic remission and regression to extinction of pericardial effusion at repeated echocardiographic evaluations.

    Intraoperative pneumothorax is a rare complication with a high risk of cardiorespiratory arrest by gas tamponade especially on a single lung. We report the case of a female patient aged 53 years who benefited from a left pneumonectomy on pulmonary tuberculosis sequelae. The patient presented early postoperative anemia with a left hemothorax requiring an emergency thoracotomy. In perioperative, the patient had a gas tamponade following a pneumothorax of the remaining lung, and the fate has been avoided by an exsufflation. Intraoperative pneumothorax can occur due to lesions of the tracheobronchial airway, of the brachial plexus, the placement of a central venous catheter or barotrauma. The diagnosis of pneumothorax during unipulmonary ventilation is posed by the sudden onset of hypoxia associated with increased airway pressures and hypercapnia. The immediate life-saving procedure involves fine needle exsufflation before the placement of a chest tube. Prevention involves reducing the risk of barotrauma by infusing patients with low flow volumes and the proper use of positive airway pressure, knowing that despite protective ventilation, barotraumas risk still exists.

    Arrhythmia origin in close proximity to the phrenic nerve (PN) can hinder successful catheter ablation. We describe our approach with epicardial PN displacement in such instances. PN displacement via percutaneous pericardial access was attempted in 13 patients (age 49±16 years, 9 females) with either atrial tachycardia (6 patients) or atrial fibrillation triggered from a superior vena cava focus (1 patient) adjacent to the right PN or epicardial ventricular tachycardia origin adjacent to the left PN (6 patients). An epicardially placed steerable sheath/4 mm-catheter combination (5 patients) or a vascular or an esophageal balloon (8 patients) was ultimately successful. Balloon placement was often difficult requiring manipulation via a steerable sheath. In 2 ventricular tachycardia cases, absence of PN capture was achieved only once the balloon was directly over the ablation catheter. In 3 atrial tachycardia patients, PN displacement was not possible with a balloon; however, a steerable sheath/catheter combination was ultimately successful. PN displacement allowed acute abolishment of all targeted arrhythmias. No PN injury occurred acutely or in follow up. Two patients developed acute complications (pleuro-pericardial fistula 1 and pericardial bleeding 1). Survival free of target arrhythmia was achieved in all atrial tachycardia patients; however, a nontargeted ventricular tachycardia recurred in 1 patient at a median of 13 months' follow up. Arrhythmias originating in close proximity to the PN can be targeted successfully with PN displacement with an epicardially placed steerable sheath/catheter combination, or balloon, but this strategy can be difficult to implement. Better tools for phrenic nerve protection are desirable. © 2015 American Heart Association, Inc.

    Pericardial effusion can cause haemodynamic compromise after heart transplantation. We identified the effects of soft drains on the development of pericardial effusion. We enrolled 250 patients ≥17 years of age who underwent heart transplantation between July 1999 and April 2012 and received two conventional tubes (n = 96; 32 French), or two tubes with a soft drain (n = 154; 4.8 mm wide). The development of significant pericardial effusion or the need for drainage procedure during 1 month after heart transplantation was compared with the use of the propensity score matching method to adjust for selection bias. At 1 month after transplantation, 69 patients (27.6%) developed significant pericardial effusion. Among these, 13 patients (5.2%) underwent pericardial drainage. According to multivariate analysis, history of previous cardiac surgery [odds ratio (OR) = 0.162; 95% confidence interval (CI) = 0.046-0.565; P = 0.004] and placement of a soft drain (OR = 0.186; 95% CI = 0.100-0.346; P effusion or the need for drainage during the early postoperative period. For the 82 propensity score matched pairs, patients receiving an additional soft drain were at a lower risk of the development of significant pericardial effusion or the need for a pericardial drainage procedure during 1 month (OR = 0.148; 95% CI = 0.068-0.318; P effusion and decreases the need for pericardial drainage after heart transplantation. © The Author 2015.

    BACKGROUND Primary cardiac lymphoma is rare and can be an aggressive disease, depending on the grade. A case is reported of low-grade primary cardiac lymphoma associated with a pericardial effusion. 18F-fluorodeoxyglucose positron emission tomography and computed tomography (FDG-PET/CT) imaging was useful in the diagnosis and in evaluating the disease activity in this case. CASE REPORT A 72-year-old Japanese woman visited a general practitioner, complaining of dyspnea associated with cardiac tamponade. Pericardiocentesis was performed, and Group V malignant cells were identified by cytology, suspicious for malignant lymphoma. Whole-body FDG-PET/CT scans showed no pleural effusion or lymph node metastasis supporting the diagnosis of primary cardiac lymphoma diagnosed on pericardial effusion. The laboratory investigations showed that levels of serum soluble interleukin-2 (IL-2) receptor (sIL-2R), a diagnostic and prognostic marker for malignant lymphoma, were not elevated (258 U/ml). A six-month follow-up FDG-PET/CT scan showed an increased volume of the pericardial effusion and mild but abnormal uptake diffusely in the pericardial space, and the sIL-2R was slightly elevated (860 U/ml). No abnormal FDG accumulation outside the retained pericardial effusion was noted, which was compatible with a clinical picture of low-grade primary cardiac lymphoma, and in a period of watchful waiting during the first two years later, the sIL-2R had reduced to 195 U/ml. CONCLUSIONS This is a rare case of low-grade primary cardiac lymphoma detected in a pericardial effusion, and highlights the utility of the FDG-PET/CT scan as a valuable diagnostic and follow-up modality.

    2013-01-01

    Abstract Pulmonary arterial hypertension (PAH) is a serious condition that can lead to right heart failure and death. Pericardial effusion in PAH is associated with significant morbidity and mortality, and its pathogenesis is complex and poorly understood. There are few data on the prevalence of pericardial effusion in PAH, and more importantly, the management of pericardial effusion is controversial. Current literature abounds with case reports, case series, and retrospective studies that have limited value for assessing this association. Hence, we summarize the available evidence on this ominous association and identify areas for future research. PMID:24618534

    A total of 167 patients with pericardial thickening noted on M node echocardiography were studied retrospectively. After the echocardiogram, 72 patients underwent cardiac surgery, cardiac catheterization or autopsy for various heart diseases; 96 patients had none of these procedures. In 49 patients the pericardium was directly visualized at surgery or autopsy; 76 percent of these had pericardial thickening or adhesions. In another 8 percent, pericardial adhesions were absent, but no comment had been made about the appearance of the pericardium itself. In the remaining 16 percent, no comment had been made about the pericardium or percardial space. Cardiac catheterization in 64 patients revealed 24 with hemodynamic findings of constrictive pericarditis or effusive constrictive disease. Seven echocardiographic patterns consistent with pericardial adhesions or pericardial thickening are described and related when possible to the subsequent findings at heart surgery or autopsy. The clinical diagnoses of 167 patients with pericardial thickening are presented. The hemodynamic diagnosis of constrictive pericardial disease was associated with the echocardiographic finding of pericardial thickening, but there were no consistent echocardiographic patterns of pericardial thickening diagnostic of constriction. However, certain other echocardiographic abnormalities of left ventricular posterior wall motion and interventricular septal motion and a high E-Fo slope were suggestive of constriction.

  1. More than just a urinary catheter — Haemorrhage control by using a Foley catheter in a penetrating aortic root injury

    2016-08-01

    Full Text Available The prevalence of great vessel injuries in thoracic trauma is reported at 0.3–10%, predominantly due to a penetrating mechanism. Thoracic aortic injuries, more specifically those within proximity of the aortic root are challenging to manage and unceasing bleeding hampers adequate visualisation for performing repair. We report a case of a 31-year-old male that presented to the emergency department 1 h after sustaining a stab wound injury within proximity of the left upper sternal border. Vital signs were stable on presentation. Physical examination revealed a 1.5 cm laceration in the 3rd intercostal space. Chest X-ray revealed a small left pneumothorax, FAST scan was negative, and CT of the chest revealed left sided haemopneumothorax and haemopericardium. The patient was emergently transferred to the operating room where median thoracotomy was performed. A significant amount of bleeding was observed originating from a 1 cm laceration of the aortic root. Bleeding was controlled using a Foley catheter after unsuccessful attempts of digital compression, and the laceration was repaired using pledgeted sutures. Postoperative echocardiography and CT scan of the chest revealed normal cardiac functions with resolution of haemopericardium and haemopneumothorax, and the patient was discharged in a stable condition. High index of suspicion should be maintained for injury to the great vessels in patients with penetrating chest injuries, despite apparent haemodynamic stability. In this case, balloon tamponade using a Foley catheter served as a quick and simple technique that resulted in an almost bloodless field, facilitating adequate visualisation for definitive repair. Although the use of this technique has been previously described, this report serves as a reminder that a Foley catheter can be successfully used for balloon catheter tamponade in injuries to the aortic root.

    2014-02-14

    Retinal detachment (RD) with proliferative vitreoretinopathy (PVR) often requires surgery to restore normal anatomy and to stabilize or improve vision. PVR usually occurs in association with recurrent RD (that is, after initial retinal re-attachment surgery) but occasionally may be associated with primary RD. Either way, a tamponade agent (gas or silicone oil) is needed during surgery to reduce the rate of postoperative recurrent RD. The objective of this review was to assess the relative safety and effectiveness of various tamponade agents used with surgery for retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR). We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 5), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to June 2013), EMBASE (January 1980 to June 2013), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to June 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 26 June 2013. We included randomized controlled trials (RCTs) of participants undergoing surgery for RD associated with PVR that compared various tamponade agents. Two review authors screened the search results independently. We used the standard methodological procedures expected by The Cochrane Collaboration. The review included 516 participants from three RCTs. One study was conducted in the USA and consisted of two trials: the first trial randomized 151 adults to receive either silicone oil or sulfur hexafluoride (SF6) gas tamponades; and the second trial randomized 271 adults to receive either

    Full Text Available PURPOSE: To characterize patients with neoplastic pericardial disease diagnosed by clinical presentation, complementary test findings, and the histological type of tumor. METHODS: Twenty-six patients with neoplastic pericardial disease were retrospectively analyzed. RESULTS: Clinical manifestations and abnormalities in chest roentgenograms and electrocardiograms were frequent, but were not specific. Most patients underwent surgery. There was a high positivity of the pericardial biopsy when associated with the cytological analysis of the pericardial liquid used to determine the histological type of the tumor, particularly when the procedure was performed with the aid of pericardioscopy. CONCLUSION: The correct diagnosis of neoplastic pericardial disease involves suspicious but nonspecific findings during clinical examination and in screen tests. The suspicious findings must be confirmed through more invasive diagnostic approaches, in particular pericardioscopy with biopsy and cytological study.

    Although pulmonary artery banding (PAB) is a common palliative procedure for pediatric heart malformation, there are concerns of pressure overload and concomitant immune reactions in the right ventricle causing postsurgical complications such as pericardial effusion. At this time, no clear guidelines as to potential risk factors or procedural contraindications have been widely disseminated. Therefore, a study was undertaken to examine wide-ranging factors to find potential biomarkers for postsurgical pericardial effusion formation risk. A retrospective study was conducted on all cardiac surgeries performed over an eight-year period, and the main inclusion criterion was pericardial effusion development after PAB that required surgical drainage. Nine cases were then analyzed against a control group of 45 cases with respect to body measurements, concomitant surgeries, genetic screens, laboratory tests results, and cardiac function parameters. Trisomy 21 was strongly associated with the development of severe pericardial effusion after PAB, and postoperative serum albumin levels in patients with trisomy 21 were associated with pericardial effusion development. Other parameters showed no significant correlation with pericardial effusion development. Our data indicate a strong association between trisomy 21 and pericardial effusion requiring drainage after PAB, which is in line with translational research findings. Pressure overload from PAB may play a role in the formation of severe pericardial effusion that is exacerbated by cardiac structural defects commonly associated with trisomy 21. Surgical teams should therefore use caution and plan to implement drainage in PAB cases, and postoperative serum albumin may serve as a useful biomarker for pericardial effusion formation.

    Full Text Available Background: We recently reported that large amounts of oral bacterial DNA can be found in thrombus aspirates of myocardial infarction patients. Some case reports describe bacterial findings in pericardial fluid, mostly done with conventional culturing and a few with PCR; in purulent pericarditis, nevertheless, bacterial PCR has not been used as a diagnostic method before. Objective: To find out whether bacterial DNA can be measured in the pericardial fluid and if it correlates with pathologic–anatomic findings linked to cardiovascular diseases. Methods: Twenty-two pericardial aspirates were collected aseptically prior to forensic autopsy at Tampere University Hospital during 2009–2010. Of the autopsies, 10 (45.5% were free of coronary artery disease (CAD, 7 (31.8% had mild and 5 (22.7% had severe CAD. Bacterial DNA amounts were determined using real-time quantitative PCR with specific primers and probes for all bacterial strains associated with endodontic disease (Streptococcus mitis group, Streptococcus anginosus group, Staphylococcus aureus/Staphylococcus epidermidis, Prevotella intermedia, Parvimonas micra and periodontal disease (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Fusobacterium nucleatus, and Dialister pneumosintes. Results: Of 22 cases, 14 (63.6% were positive for endodontic and 8 (36.4% for periodontal-disease-associated bacteria. Only one case was positive for bacterial culturing. There was a statistically significant association between the relative amount of bacterial DNA in the pericardial fluid and the severity of CAD (p=0.035. Conclusions: Oral bacterial DNA was detectable in pericardial fluid and an association between the severity of CAD and the total amount of bacterial DNA in pericardial fluid was found, suggesting that this kind of measurement might be useful for clinical purposes.

    Full Text Available Background: Hashimoto thyroiditis (HT is the most frequent cause of acquired hypothyroidism in paediatrics. HT is usually diagnosed in older children and adolescents, mainly in females and is rare in infants and toddlers with cardiac involvement, including pericardial effusion, that can be found in 10% to 30% of adult HT cases. In this paper, a child with HT and pericardial effusion as the most important sign of HT is described. Case presentation: A four-year-old male child suffering for a few months from recurrent abdominal pain sometimes associated with vomiting underwent an abdominal ultrasound scan outside the hospital. This led to the identification of a significant pericardial effusion. At admission, his family history revealed that both his mother and maternal grandmother suffered from HT and that both were treated with l-thyroxine (LT4. The clinical examination did not reveal any pathological signs other than a palpable thyroid. His weight was 21 kg (78th percentile, his height was 101.8 cm (12th percentile and his body max index (BMI was 20.26 (96th percentile. On a chest radiograph, his heart had a globular appearance and the lung fields were normal. An echocardiography confirmed and determined the effusion amount (max, 23 mm; 600 mL with light impairment of the heart kinetics. The ECG showed sinus bradycardia with a normal ST tract. Based on the blood test results, an infectious cause of the pericardial fluid excess was considered unlikely.

    Chylous pericardial effusion is a rarely reported complication of lung cancer surgery. Here, we report a case of an elderly man who suffered chylous pericardial effusion after radical right upper lung resection for cancer. The massive chylous effusion first occurred in the pericardium, drained to the right chest after the drainage of the hydropericardium and subsequently moved back to the pericardium again. Lymphoscintigraphy examination indicated that a chylous fistula was present in the plane of the tracheal carina. After failure to control the chylous effusion with conservative medical treatment, the patient underwent video-assisted thoracic surgery through the left chest for thoracic duct ligation and pericardial fenestration. The patient was ultimately discharged without recurrence of the effusion after surgical treatment. This case report discusses the possible mechanism of chylopericardium after lung cancer surgery and suggests some strategies to prevent postoperative chylous pericardial effusion. © The Author 2017.

    Objective: To assess the effectiveness and clinical outcome and technique of CT-guided pericardiocenteses in the treatment of pericardial effusions in adults and children. Methods: 20 drainages were performed in Seldinger-technique under CT-guidance on 20 patients suffering from pericardial effusions and haematomas. In 85%, the etiology of effusion was postoperative. The mean age of the patients was 59 years (minimum 9 years, maximum 86 years).There were 12 male and eight female patients. The inclusion criterion was an echocardiographically relevant proved pericardial effusion. Results: All catheters could be placed successfully (20/20) in the pericardial effusion and allowed for draining of the effusion in all cases under CT-guidance. The overall 30-day mortality rate was 0%. CT-guided pericardiocentesis was successful for withdrawing pericardial fluid and/or relieving tamponade in 100% of all procedures. No major complication was occurred. A total of one minor complication (5%) occurred that required no specific interventions, except for monitoring and appropriate follow-up. We observed one pneumothorax as a minor complication. Conclusions: Pericardial effusions of various causes can be safely, effectively, and quickly managed with CT-guided pericardiocenteses in adults and children. The ventrolateral entry side for the puncture should be preferred to reach the whole effusion and avoid complications, like a pneumothorax.

  14. Pericardial Parietal Mesothelial Cells: Source of the Angiotensin-Converting-Enzyme of the Bovine Pericardial Fluid

    Directory of Open Access Journals (Sweden)

    Ilsione Ribeiro de Sousa Filho

    Full Text Available Abstract Background: Angiotensin II (Ang II, the primary effector hormone of the renin-angiotensin system (RAS, acts systemically or locally, being produced by the action of angiotensin-converting-enzyme (ACE on angiotensin I. Although several tissue RASs, such as cardiac RAS, have been described, little is known about the presence of an RAS in the pericardial fluid and its possible sources. Locally produced Ang II has paracrine and autocrine effects, inducing left ventricular hypertrophy, fibrosis, heart failure and cardiac dysfunction. Because of the difficulties inherent in human pericardial fluid collection, appropriate experimental models are useful to obtain data regarding the characteristics of the pericardial fluid and surrounding tissues. Objectives: To evidence the presence of constituents of the Ang II production paths in bovine pericardial fluid and parietal pericardium. Methods: Albumin-free crude extracts of bovine pericardial fluid, immunoprecipitated with anti-ACE antibody, were submitted to electrophoresis (SDS-PAGE and gels stained with coomassie blue. Duplicates of gels were probed with anti-ACE antibody. In the pericardial membranes, ACE was detected by use of immunofluorescence. Results: Immunodetection on nitrocellulose membranes showed a 146-KDa ACE isoform in the bovine pericardial fluid. On the pericardial membrane sections, ACE was immunolocalized in the mesothelial layer. Conclusions: The ACE isoform in the bovine pericardial fluid and parietal pericardium should account at least partially for the production of Ang II in the pericardial space, and should be considered when assessing the cardiac RAS.

    Rheumatic disorders can be associated with pericarditis, but severe forms of pericarditis are rare. The aim of this observational study was to evaluate pericardial features in patients with different rheumatic diseases. Thirty-five patients hospitalized at the Clinic of Rheumatology, University Clinical Center of Kosovo, from October 1 to October 21, 2014 were included in the study. Demographic data, history, laboratory, ECG, and echocardiography data, with special emphasis on the analysis of the pericardium, were obtained from each patient. Echocardiography was especially focused on the amount of pericardial fluid and pericardial thickness in the posterior wall of the heart. Mean patient age was 51.5 ± 13.8 years. 65.7% of the patients were women. Out of the patients that we analyzed, 88.6% had an inflammatory rheumatologic disease. 11.3% of the patients had mild symptoms, in 68.7% the symptoms were moderate, and in 20% severe. In all patients, pericardial hyperechogenicity was marked, with a mean pericardial thickness of 4.68 ± 1.66 mm. Pericardial effusion in a small amount was present in 57.1% of patients, with a mean pericardial fluid amount of 3.3 ± 1.9 mm. The severity of rheumatic disease had a positive and significant correlation with the presence of pericardial effusion (r= 0.29, p=0.04) and its amount (r= 0.28, p=0.05). The patients had not been aware of the pericardial involvement and did not have any clinical symptoms. In conclusion, in this short-term small observational study pericardial changes were a frequent finding in the rheumatology patients. In general, the pericarditis was subclinical and with small amounts of effusion. The disease activity of rheumatic disorders can be associated with pericarditis. Further studies with larger samples of patients and of longer duration are needed to further explore this issue.

    Full Text Available Catheter-associated urinary tract infections (CAUTI are among the most common healthcare-associated infections, and potentially lead to significant morbidity and mortality. Multifaceted infection control strategies implemented as bundles can prevent nosocomial infections associated with invasive devices such as CAUTIs. The components of the CAUTI bundle proposed herein, include appropriate indications for catheterization and recommendations for the procedures of catheter insertion and catheter maintenance and care. Avoiding unnecessary urinary catheter use is the most effective measure for their prevention. To minimize the risk of CAUTI, urinary catheters should be placed only when a clinical valid indication is documented and they should be removed as soon as possible; alternatives to catheterization should also be considered. Aseptic insertion technique, maintenance of closed drainage system and strict adherence to hand hygiene are essential for preventing CAUTI. The successful implementation of the bundle requires education and training for all healthcare professionals and evaluation of surveillance data.

    Full Text Available AIM: To report the results of combined vitrectomy, lensectomy and silicone oil (SO tamponade in treating primary rhegmatogenous retinal detachment (RRD associated with choroidal detachment (CD.METHODS: A retrospective, consecutive and case series study of 21 subjects with concurrent RRD associated with CD was conducted. All subjects underwent a standard three-port 20G pars plana vitrectomy (PPV with lensectomy and silicone oil tamponade. Mean follow-up time was 8 months (rang from 4 to 19 months. The primary and final anatomic success rate, visual acuity and final intraocular pressure(IOP were recorded and analyzed.RESULTS: Of 21 subjects, 8 were women and 13 were men. Age at presentation ranged from 22 to 75 years (mean 57.4 years. The presenting vision ranged from light perception to 0.15. The initial IOP ranged from 3mmHg to 12mmHg (mean 6.2mmHg. All eyes were phakic except one pseudophakic. No intraocular lens was implanted during the primary surgical intervention. Fifteen of 21 (71.4% eyes had retina reattached after one operation. Six eyes had recurrent inferior retinal detachment due to proliferation. Five of them were successfully reattached after one or more additional operations. Mean IOP at final follow-up was 15.2mmHg (range from 8mmHg to 20mmHg. One case declined for further operation. The final reattachment rate was 95.2%. Visual acuity improved in 19 (90.5% eyes, was unchanged in 1 (4.8% eye and decreased in 1 (4.8% eye.CONCLUSION: Combination of vitrectomy, lensectomy and silicone tamponade is an effective method in treating RRD associated with CD, reducing the incidence of postoperative hypotony.

    To assess the effectiveness and safety of uterine packing versus Foley's catheter tamponade for controlling postpartum hemorrhage (PPH) secondary to bleeding tendency after vaginal delivery. This was a prospective observational study conducted on 92 patients with primary PPH due to bleeding tendency following vaginal delivery who were unresponsive to uterotonics and bimanual compression of the uterus. Patients were divided into two groups, Uterine packing group (n = 45) and Foley catheter group (n = 47). The primary outcome was the success rate of the procedure. Secondary outcome addressed the maternal complications. The use of uterine packing resulted in stoppage of active bleeding in 93.3% of cases compared to only 68.1% in the Foley's catheter group (p  0.05). Six cases who failed to Foley catheter tamponade underwent emergency hysterectomy with no cases in the uterine packing group. The use of uterine packing to arrest PPH is simple, quick and safe procedure to avoid further surgical interventions and to preserve the fertility in low-resource setting.

    Full Text Available This study aimed to investigate the clinical application value of the 5-fluorouracil (5-FU sustained-release particles implanted along the cardiac tangent direction into malignant pericardial effusion (MPCE. A total of 81 MPCE patients underwent pericardiocentesis, and were implanted with 5-FU sustained-release particles into the pericardial cavity under ultrasound guidance. The puncturing path was along the cardiac tangent direction. Ultrasound examinations were performed every week, and the efficacy was evaluated 4 weeks after treatment. The 45 patients who were treated with pericardial catheter drainage and simultaneous intracavitary chemotherapy were used as the control group. The success rate of pericardiocentesis was 100%. Ultrasound reviews performed 4 weeks after treatment showed that 71 cases achieved complete remission and eight cases achieved partial remission, while treatment was completely ineffective in two cases. The total remission rate was 97.53%, which was significantly higher than that of the control group (77.78%, p < 0.01. The implantation of 5-FU sustained-release particles along the cardiac tangent direction was safe, and demonstrated good efficacy and fewer adverse reactions. Thus, this method could be ideal for the treatment of MPCE.

  20. Contemporary management of pericardial diseases.

    Imazio, Massimo

    2012-05-01

    Pericardial diseases are relatively common in clinical practice, either as isolated disease or as manifestation of a systemic disorder. The aim of the present study is to review more recent updates on their contemporary management. The cause of pericardial diseases is varied according to the epidemiologic background, patient population, and clinical setting. Most cases remain idiopathic, and empiric anti-inflammatory therapy should be considered as first-line therapy in most cases with the possible adjunct of colchicine in the setting of inflammatory pericardial diseases, especially relapsing or not responding to first-line drugs. A triage has been proposed to select high-risk cases requiring admission and specific cause search. The prognosis of pericardial diseases is essentially determined by the cause. The most feared complication is constriction, the risk of which is higher in bacterial forms, intermediate for postpericardiotomy syndromes and systemic inflammatory diseases, low for viral and idiopathic cases. Chronic constriction has a definite surgical therapy, whereas transient cases should be recognized and may be reversible with empirical anti-inflammatory therapy. Contemporary management of pericardial diseases is largely empirical, although first clinical trials and new studies on diagnostic modalities and prognosis of pericardial diseases are bringing the contemporary management of pericardial diseases along a more evidence-based road. Integrated cardiovascular imaging is required for optimal management of the patient with suspected pericardial disease.

    To describe and explore relationships among catheter problems in long-term indwelling urinary catheter users, including excess healthcare use for treating catheter problems. Long-term urinary catheter users experience repeated problems with catheter-related urinary tract infection and blockage of the device, yet little has been reported of the patterns and relationships among relevant catheter variables. Secondary data analysis was conducted from a sample in a randomised clinical trial, using data from the entire sample of 202 persons over 12 months' participation. Descriptive statistics were used to characterise the sample over time. Zero-inflated negative binomial models were employed for logistic regressions to evaluate predictor variables of the presence/absence and frequencies of catheter-related urinary tract infection and blockage. Catheter-related urinary tract infection was marginally associated with catheter blockage. Problems reported at least once per person in the 12 months were as follows: catheter-related urinary tract infection 57%, blockage 34%, accidental dislodgment 28%, sediment 87%, leakage (bypassing) 67%, bladder spasms 59%, kinks/twists 42% and catheter pain 49%. Regression analysis demonstrated that bladder spasms were significantly related to catheter-related urinary tract infection and sediment amount, and catheter leakages were marginally significantly and positively related to catheter-related urinary tract infection. Frequencies of higher levels of sediment and catheter leakage were significantly associated with higher levels of blockage, and being female was associated with fewer blockages. Persons who need help with eating (more disabled) were also more likely to have blockages. Catheter-related urinary tract infection and blockage appear to be related and both are associated with additional healthcare expenditures. More research is needed to better understand how to prevent adverse catheter outcomes and patterns of problems in

    Full Text Available Nasopharyngeal carcinoma (NPC is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein–Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.

    Full Text Available ABSTRACT Objective: to investigate the incidence of phlebitis and its association with risk factors when using peripheral IV catheters (PIC and following their removal - (post-infusion phlebitis in hospitalized adults. Method: a cohort study of 171 patients using PIC, totaling 361 punctures. Sociodemographic variables and variables associated with the catheter were collected. Descriptive and analytical statistical analyses were performed. Results: average patient age was 56.96 and 51.5% of the sample population was male. The incidence of phlebitis was 1.25% while using PIC, and 1.38% post-infusion. The incidence of phlebitis while using PIC was associated with the length of time the catheter remained in place, whereas post-infusion phlebitis was associated with puncture in the forearm. Ceftriaxone, Clarithromycin and Oxacillin are associated with post-infusion phlebitis. Conclusions: this study made it possible to investigate the association between risk factors and phlebitis during catheter use and following its removal. The frequency of post-infusion phlebitis was larger than the incidence of phlebitis with the catheter in place, with Phlebitis Grade III and II being the most frequently found in each of these situations, respectively. Aspects related to post-infusion phlebitis can be explained, given the limited number of studies addressing this theme from this perspective.

    Results: A 90% relative risk reduction in the rate of CAUTI was observed with the noble metal alloy catheter compared to the standard catheter (10 vs. 1 cases, P = 0.006. When considering both catheter-associated asymptomatic bacteriuria and CAUTI, the relative risk reduction was 83% (12 vs. 2 cases, P = 0.005. In addition to CAUTI, the risk of acquiring secondary bacteremia was lower (100% for the patients using noble metal alloy catheters (3 cases in the standard group vs. 0 case in the noble metal alloy catheter group, P = 0.24. No adverse events related to any of the used catheters were recorded. Conclusion: Results from this study revealed that noble metal alloy catheters are safe to use and significantly reduce CAUTI rate in ICU patients after 3 days of use.

    Pericardial effusions following radiotherapy for Hodgkins Disease have previously been described as infrequent and related to the total dose of radiation received. Analysis of all chest x-rays on 81 patients who received upper-mantle radiotherapy for Hodgkins Disease at the Baltimore Cancer Research Center between 1968 and 1972 disclosed an incidence of pericardial effusions of 30.9% (25 of 81), with 13.6% (11 of 81) requiring limitation of activity (5) or pericardiectomy (6). Clinical presentation of radiation-related pericardial effusions was subtle, with signs and symptoms a late finding if they occurred. Radiotherapy data was reviewed and no difference in total dose (rads) or time-dose relationships (rets) was found between the groups who did or did not develop effusions. Analysis of multiple pre-treatment clinical and pathological characteristics disclosed four parameters that were felt to be related to the development of pericardial effusions; elevated ESR, normal absolute lymphocyte count, initial presence of extensive mediastinal adenopathy and the addition of adjuvant chemotherapy. The presence of increasing combinations of these pretreatment 'risk factors' led to an increasing likelihood of developing a radiation-related pericardial effusion such that six of seven patients with all four 'risk factors' developed a pericardial effusion. Nine of 13 clinically significanteffusions were associated with the addition of adjuvant chemotherapy. Possible pathogenetic mechanisms that include factors other than radiation dosage and the clinical management of radiation-related pericardial effusions are discussed

    The imaging features of primary pericardial mesothelioma have rarely been described. Herein we present a case report of its diagnostic-pathologic features. Chest computed tomography (CT) revealed an irregularly enhanced mass occupying the entire pericardial space and surrounding the superior vena cava. At autopsy, the tumor was found to fill the pericardial space completely, and to extend to the superior vena cava through the superior pericardial sinus. The CT features of the tumor were correlated well with those revealed at autopsy, and provided satisfactory information regarding the presence and the extension of the tumor. (orig.)

    Comparative outcomes of patients undergoing pericardiocentesis or pericardial window are limited. Development of pericardial effusion after cardiac surgery is common but no data exist to guide best management. Procedural billing codes and Cleveland Clinic surgical registries were used to identify 1,281 patients who underwent either pericardiocentesis or surgical pericardial window between January 2000 and December 2012. The 656 patients undergoing an intervention for a pericardial effusion secondary to cardiac surgery were also compared. Propensity scoring was used to identify well-matched patients in each group. In the overall cohort, in-hospital mortality was similar between the group undergoing pericardiocentesis and surgical drainage (5.3% vs 4.4%, p = 0.49). Similar outcomes were found in the propensity-matched group (4.9% vs 6.1%, p = 0.55). Re-accumulation was more common after pericardiocentesis (24% vs 10%, p <0.0001) and remained in the matched cohorts (23% vs 9%, p <0.0001). The secondary outcome of hemodynamic instability after the procedure was more common in the pericardial window group in both the unmatched (5.2% vs 2.9%, p = 0.036) and matched cohorts (6.1% vs 2.0%, p = 0.022). In the subgroup of patients with a pericardial effusion secondary to cardiac surgery, there was a lower mortality after pericardiocentesis in the unmatched group (1.5% vs 4.6%, p = 0.024); however, after adjustment, this difference in mortality was no longer present (2.6% vs 4.5%, p = 0.36). In conclusion, both pericardiocentesis and surgical pericardial window are safe and effective treatment strategies for the patient with a pericardial effusion. In our study there were no significant differences in mortality in patients undergoing either procedure. Observed differences in outcomes with regard to recurrence rates, hemodynamic instability, and in those with postcardiac surgery effusions may help to guide the clinician in management of the patient

    The success of catheter ablation of focal atrial tachycardia is limited by possible collateral damage to the phrenic nerve. Protection of the phrenic nerve is required. Here we present a case of a 9-year-old girl having a history of an unsuccessful catheter ablation of a focal atrial tachycardia near the crista terminalis (because of proximity of the phrenic nerve) who underwent a successful ablation by means of a novel technique for phrenic nerve protection: packing of gauze into the pericardial space. This method is a viable approach for patients with a failed endocardial ablation due to the proximity of the phrenic nerve.

    To investigate evidence for selected vector-borne pathogen infections in dogs with pericardial effusion living in a Mediterranean area in which several canine vector-borne diseases are endemic. Archived EDTA blood (n=68) and pericardial fluid samples (n=58) from dogs with pericardial effusion (n=68) were included. Dogs without pericardial effusion examined for other reasons were included as controls (n=60). Pericardial effusion was classified as neoplastic in 40 dogs, idiopathic in 23 dogs and of unknown aetiology in 5 dogs. Real-time PCR was performed for Leishmania infantum, Ehrlichia/Anaplasma species, Hepatozoon canis, Babesia species, Rickettsia species and Bartonella species, and sequencing of PCR products from positive samples was used to confirm species specificity. Vector-borne pathogens were found in 18 dogs: 16 of 68 dogs with pericardial effusion (23·5%) and two of 60 control dogs (3·3%). Positive dogs demonstrated DNA of Leishmania infantum (n=7), Anaplasma platys (n=2, one dog coinfected with Leishmania infantum), Babesia canis (n=5), Babesia gibsoni (n=3) and Hepatozoon canis (n=2). Vector-borne pathogens were more commonly detected among dogs with pericardial effusion than controls (P=0·001). There was no relationship between aetiology of the pericardial effusion and evidence of vector-borne pathogens (P=0·932). Vector-borne pathogens are often detected in dogs with pericardial effusion and require further investigation, especially in dogs with idiopathic pericardial effusion. PCR can provide additional information about the potential role of vector-borne pathogens in dogs with pericardial effusion living in endemic areas. © 2018 British Small Animal Veterinary Association.

    Pericardial effusion is the accumulation of abnormal fluid in the pericardial cavity. The symptoms are not specific and associated with the underlying disease. It was reported that a 53-year-old male patient entered the Emergency Room with a shortness of breath, and getting worse during activity and position. There was weight loss and smoking history. The history of diabetic, hypertension and malignancy were denied. On physical examination showed the enlarged right and left heart border and weakened heartbeat sheer off is found and edema pretibial and normal the other. The laboratory results;blood routine, renal and liver function within normal; lipid profile: hypercholesterolemia; viral marker is non-reactive.Rontgen thorax suggests cardiomegaly, but there was no infiltrate or nodules. Electrocardiogram (ECG) showed a low voltage. Echocardiography examination showed massive pericardial effusion. Pericardiosynthetis performed produces 750 cc of clear yellow liquid and showed transudate. Other laboratory tests such as ANA test, anti ds-DNA, cyfra were a normal impression. Thyroid function: hypothyroid, Mantoux test is negative. Finally, the patient is a massive pericardial effusion caused by hypothyroidism. The pericardiocentesis took, and the hypothyroid drug of euthirax is administered. The patient was well done and continued for recontrol.

    Full Text Available Objectives. Chronic pericardial effusion may be challenging in terms of diagnosis and treatment. Specific laboratory parameters predicting the frequency and severity of recurrences after initial drainage of pericardial effusion are lacking. Materials and Methods. Pericardial fluid (PF and serum (SE samples from 30 patients with chronic pericardial effusion (PE who underwent pericardiocentesis and pericardioscopically guided pericardial biopsy were compared with SE and PF samples from 26 control patients. The levels of antimyolemmal (AMLA and antifibrillary antibodies (AFA in PE and SE from patients with pericardial effusion as well as PF and SE from controls were determined and compared. Results. AMLAs and AFAs in PF and SE were significantly higher in patients with chronic pericardial effusion than in the control group (AMLAs: p = 0,01 for PF and p = 0,004 for serum; AFAs: p < 0,001 for PF and p = 0,003 for serum. Patients with recurrence of PE within 3 months after pericardiocentesis had significantly higher levels of AMLAs in SE (p = 0,029 than patients without recurrence of PE. Conclusions. The identification of elevated anticardiac antibodies in PE and SE indicates increased immunological reactivity in chronic pericardial effusion. High titer serum levels of AMLAs also correlate with recurrence of pericardial effusion.

    Myopic foveoschisis (MF) is among the leading causes of visual loss in high myopia. However, it remains controversial whether internal limiting membrane (ILM) peeling or gas tamponade is necessary treatment option for MF. PubMed, EMBASE, CBM, CNKI, WANFANG DATA and VIP databases were systematically reviewed. Outcome indicators were myopic foveoschisis resolution rate, visual acuity improvement and postoperative complications. Nine studies that included 239 eyes were selected. The proportion of resolution of foveoschisis was higher in ILM peeling group than non-ILM peeling group (OR = 2.15, 95% CI: 1.06-4.35; P = 0.03). The proportion of postoperative complications was higher in Tamponade group than non-Tamponade group (OR = 10.81, 95% CI: 1.26-93.02; P = 0.03). However, the proportion of visual acuity improvement (OR = 1.63, 95% CI: 0.56-4.80; P = 0.37) between ILM peeling group and non-ILM peeling group and the proportion of resolution of foveoschisis (OR = 1.80, 95% CI: 0.76-4.28; P = 0.18) between Tamponade group and non-Tamponade group were similar. Vitrectomy with internal limiting membrane peeling could contribute to better resolution of myopic foveoschisis than non-peeling, however it does not significantly influence the proportion of visual acuity improvement and postoperative complications. Vitrectomy with gas tamponade is associated with more complications than non-tamponade and does not significantly influence the proportion of visual acuity improvement and resolution of myopic foveoschisis.

    Catheter-associated urinary tract infections account for 30% of healthcare-associated infections. To date, few studies have addressed pediatric catheter-associated urinary tract infection in PICUs. The aim of our study was to assess the risk of catheter-associated urinary tract infection in relation to the duration of catheterization in the PICU. Retrospective cohort study. PICU at a tertiary children's hospital. Our study was conducted between April 2012 and June 2015 at Tokyo Metropolitan Children's Medical Center in Japan. Children in the PICU with an urethral catheter were included. Catheter-associated urinary tract infection cases were defined according to the National Healthcare Safety Network criteria. The patients' demographic data and isolated organisms were reviewed. Duration of catheterization and the catheter-associated urinary tract infection occurrence rate were analyzed. None. Among 1,890 catheterizations, 23 catheter-associated urinary tract infection cases were identified. The overall occurrence rate was 2.35/1,000 catheter-days. Among the patients with catheter-associated urinary tract infection, 13 were boys. The median age was 11 months (interquartile range, 7-35 mo), and the median duration of catheterization was 7 days (interquartile range, 5-12 d). The isolated bacteria were Escherichia coli (26.5%), Enterococcus faecalis (17.6%), and Klebsiella pneumoniae (11.8%). Two species were isolated in each of 11 cases (47.8%). Each additional day of catheterization increased the risk of catheter-associated urinary tract infection (odds ratio, 1.06; 95% CI, 1.02-1.10, and odds ratio adjusted for contact precaution status and surgical procedures was 1.05; 95% CI, 1.01-1.09). Longer duration of catheterization increased the risk of catheter-associated urinary tract infection by 5% each day at the PICU. Prompt removal of the urethral catheter is strongly recommended whenever feasible.

    Full Text Available Abstract The pericardium and pericardial diseases in particular have received, in contrast to other topics in the field of cardiology, relatively limited interest. Today, despite improved knowledge of pathophysiology of pericardial diseases and the availability of a wide spectrum of diagnostic tools, the diagnostic challenge remains. Not only the clinical presentation may be atypical, mimicking other cardiac, pulmonary or pleural diseases; in developed countries a shift for instance in the epidemiology of constrictive pericarditis has been noted. Accurate decision making is crucial taking into account the significant morbidity and mortality caused by complicated pericardial diseases, and the potential benefit of therapeutic interventions. Imaging herein has an important role, and cardiovascular magnetic resonance (CMR is definitely one of the most versatile modalities to study the pericardium. It fuses excellent anatomic detail and tissue characterization with accurate evaluation of cardiac function and assessment of the haemodynamic consequences of pericardial constraint on cardiac filling. This review focuses on the current state of knowledge how CMR can be used to study the most common pericardial diseases.

    Antimicrobial lock therapy has been widely utilized internationally for the prevention and management of intravascular catheter-related bloodstream infections. One of the agents commonly utilized for lock therapy is ethanol. However, a systematic review of adverse events associated with ethanol locks has not been published. PubMed was searched to collect articles published from May 2003 through March 2014. The bibliographies of relevant articles were also reviewed. In vitro studies of the mechanical properties of catheters after ethanol immersion have revealed changes predominantly in polyurethane catheters and to a lesser extent in silicone and Carbothane catheters. An elution of polymers from polyurethane and Carbothane catheters has been observed at the ethanol concentrations used in ethanol lock therapy. Ethanol above a concentration of 28% leads to plasma protein precipitation. Ethanol locks were associated with catheter occlusion in 11 studies and independently increased the risk of thrombosis compared with heparin lock in a randomized trial. Six studies noted abnormalities in catheter integrity, including one case leading to catheter embolization. Of note, five of these studies involved silicone catheters. Ethanol lock use was associated with systemic side effects in 10 studies and possible side effects in one additional study. Four studies noted liver function test abnormalities, predominantly transaminase elevation, related to ethanol lock use. However, a prospective study did not find any difference in the risk of doubling the transaminase level above the normal range during use of ethanol locks compared with not using an ethanol lock. The use of ethanol locks has been associated with structural changes in catheters, as well as the elution of molecules from the catheter polymers. Clinical studies have revealed systemic toxicity, increased catheter occlusion and breaches in catheter integrity. © The Author 2014. Published by Oxford University Press on

    Catheter associated urinary tract infections are an essential measure for health care quality improvement that affects reimbursement through hospital acquired condition reduction programs in adult patients. With the mounting importance of preventing such infections we evaluated risk factors for acquiring catheter associated urinary tract infections in pediatric patients. All catheter associated urinary tract infections were identified at 1 pediatric institution from September 2010 to August 2014 from a prospective database maintained by the infection control office. To identify risk factors patients with a catheter associated urinary tract infection were individually matched to control patients with a urinary catheter but without infection by age, gender, date and the hospital location of the infection in 1:2 fashion. A total of 50 patients with catheter associated urinary tract infection were identified and matched to 100 control patients. Compared to controls the patients with infection were more likely to have a catheter in place for longer (2.9 days, OR 1.08, 95% CI 1.01, 1.15, p = 0.02). They were also more likely to be on contact precautions (OR 4.00, 95% CI 1.73, 9.26, p = 0.001), and have concurrent infections (OR 3.04, 95% CI 1.39, 6.28, p = 0.005) and a history of catheterization (OR 3.24, 95% CI 1.55, 6.77, p = 0.002). Using a conditional multivariate regression model the 3 most predictive variables were duration of catheter drainage, contact isolation status and history of catheterization. Longer duration of urinary catheter drainage, positive contact precautions status and a history of catheterization appear to be associated with a higher risk of catheter associated urinary tract infection in hospitalized pediatric patients. Physicians should attempt to decrease the duration of catheterization, especially in patients who meet these criteria, to minimize the risk of catheter associated urinary tract infection.

    A 13-year-old neutered male Border Collie was presented with acute onset syncope, weakness and anorexia 10 months after transvenous pacemaker implantation. The patient was laterally recumbent, bradycardic (36 beats/min) and febrile (40.7°C) on presentation. An electrocardiogram (ECG) revealed recurrence of third-degree atrioventricular block with a ventricular escape rhythm. Fluoroscopy identified migration of the pacemaker tip through the apex of the right ventricle. Echocardiography failed to reveal any evidence of pericardial effusion or cardiac tamponade. Full postmortem was performed after euthanasia. The pacemaker lead had perforated the apex of the right ventricle and lodged in the right pleural space. Culture of blood (taken antemortem), pericardial sac, right ventricular wall (surrounding pacemaker lead), pacemaker lead tip and pericardial fluid revealed a pure growth of Moraxella phenylpyruvica. Bacteraemia associated with M. phenylpyruvica has never been reported in the dog, but sporadic cases are reported in humans. Infection could have resulted from either pre-existing myocarditis or opportunistic infection and bacteraemia post pacemaker implantation. Evaluation of the pacemaker function at regular intervals would allow early detection of poor pacemaker-to-myocardium contact, which would prompt further investigation of pacemaker lead abnormalities such as perforation. © 2016 Australian Veterinary Association.

    2012-05-01

    Full Text Available Many systemic and ocular factors may cause acute central retinal artery occlusion (CRAO. Herein, we aimed to describe a case of CRAO due to intraocular silicone oil (SO tamponade. To the best of our knowledge, a case like our has not been reported previously. A 58-yearold male patient had undergone combined pars plana vitrectomy-lensectomy and intraocular SO for lens luxation and vitreus hemorrhage associated with a blunt ocular trauma in his right eye. Two weeks after the surgery, he presented with acute vision loss in the same eye. He was diagnosed with acute CRAO and it should be related with mechanical press or raised intraocular pressure (IOP associated with SO. He was treated by partial removal of SO immediately. In spite of the regression of retina edema, his visual acuity did not improve due to optic atrophy. SO may cause CRAO due to raised IOP and/or its mechanical pressure and this complication must be kept in mind. (Turk J Oph thal mol 2012; 42: 238-40

    To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher's exact test and unpaired two-tailed t -test. One hundred and six patients (76.2%) had undergone silicone oil removal at the time of review with 96 patients (90.6%) showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity (BCVA). Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade ( P =0.0001, <0.0001 respectively). Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.

    The diagnosis and management of pericardial disease are very challenging for clinicians. The evidence base in this field is relatively scarce compared with other disease entities in cardiology. In this article, we outline a unified, stepwise pathway-based approach for the management of pericardial disease. We used the "CHASER" acronym to define the entry points into the pathway. These include chest pain, hypotension or arrest, shortness of breath, echocardiographic or other imaging finding of pericardial effusion, and right-predominant heart failure. We propose a score for the assessment of pericardial effusion that is composed of the following 3 parameters: the etiology of the effusion, the size of the effusion, and the echocardiographic assessment of hemodynamic parameters. The score is applied to clinically stable patients with pericardial effusion to quantify the necessity of pericardial effusion drainage. A stepwise, pathway-based approach to the management of pericardial disease is intended to provide guidance for clinicians in decision-making and a patient-tailored evidence-based approach to medical and surgical therapy for pericardial disease. The pathway for the management of pericardial disease is the ninth project to be incorporated into the "Advanced Cardiac Admission Program" at Saint Luke's Roosevelt Hospital Center of Columbia University in New York. Further studies should focus on the validation of the feasibility, efficacy, and reliability of this pathway.

    Catheter-associated urinary tract infection is a major hospital-acquired infection. This study aimed to analyse the effect of a silver alloy and hydrogel-coated catheter on the occurrence of catheter-associated urinary tract infection. This was a 1-year prospective study conducted at a single centre in Hong Kong. Adult patients with an indwelling urinary catheter for longer than 24 hours were recruited. The incidence of catheter-associated urinary tract infection in patients with a conventional latex Foley catheter without hydrogel was compared with that in patients with a silver alloy and hydrogel-coated catheter. The most recent definition of urinary tract infection was based on the latest surveillance definition of the National Healthcare Safety Network managed by Centers for Disease Control and Prevention. A total of 306 patients were recruited with a similar ratio between males and females. The mean (standard deviation) age was 81.1 (10.5) years. The total numbers of catheter-days were 4352 and 7474 in the silver-coated and conventional groups, respectively. The incidences of catheter-associated urinary tract infection per 1000 catheter-days were 6.4 and 9.4, respectively (P=0.095). There was a 31% reduction in the incidence of catheter-associated urinary tract infection per 1000 catheter-days in the silver-coated group. Escherichia coli was the most commonly involved pathogen (36.7%) of all cases. Subgroup analysis revealed that the protective effect of silver-coated catheter was more pronounced in long-term users as well as female patients with a respective 48% (P=0.027) and 42% (P=0.108) reduction in incidence of catheter-associated urinary tract infection. The mean catheterisation time per person was the longest in patients using a silver-coated catheter (17.0 days) compared with those using a conventional (10.8 days) or both types of catheter (13.6 days) [P=0.01]. Silver alloy and hydrogel-coated catheters appear to be effective in preventing catheter-associated

    Catheter-associated urinary tract infections (CAUTIs) are among the most common health care-associated infections in the United States, yet little is known about the prevention and epidemiology of pediatric CAUTIs. An observational study was conducted to assess the impact of a CAUTI quality improvement prevention bundle that included institution-wide standardization of and training on urinary catheter insertion and maintenance practices, daily review of catheter necessity, and rapid review of all CAUTIs. Poisson regression was used to determine the impact of the bundle on CAUTI rates. A retrospective cohort study was performed to describe the epidemiology of incident pediatric CAUTIs at a tertiary care children's hospital over a 3-year period (June 2009 to June 2012). Implementation of the CAUTI prevention bundle was associated with a 50% reduction in the mean monthly CAUTI rate (95% confidence interval: -1.28 to -0.12; P = .02) from 5.41 to 2.49 per 1000 catheter-days. The median monthly catheter utilization ratio remained unchanged; ∼90% of patients had an indication for urinary catheterization. Forty-four patients experienced 57 CAUTIs over the study period. Most patients with CAUTIs were female (75%), received care in the pediatric or cardiac ICUs (70%), and had at least 1 complex chronic condition (98%). Nearly 90% of patients who developed a CAUTI had a recognized indication for initial catheter placement. CAUTI is a common pediatric health care-associated infection. Implementation of a prevention bundle can significantly reduce CAUTI rates in children. Copyright © 2014 by the American Academy of Pediatrics.

    To determine the incidence of pericardial effusion in patients undergoing upper mantle radiation therapy, 81 patients with Hodgkin's disease, stages I to IIIB, were selected from a protocol series of 98 patients. Twenty-four patients (29.6 percent) met X-ray criteria for the presence of pericardial effusion. Eleven of the 24 also underwent right heart catheterization to confirm the presence of pericardial effusion and to define any hemodynamic abnormality. Fourteen patients were found to have transient effusion. Five of the 11 patients have had partial pericardiectomy for symptoms and signs of cardiac tamponade. There has been no evidence of recurrent Hodgkin's disease in these surgically treated patients. Ninety-two percent of the pericardial effusions occurred in the first 12 months after the end of radiation therapy. Therapeutic implications depend on elucidation of the natural history of this process. At present close follow-up is necessary with surgical intervention for signs or symptoms of cardiac tamponade

    To perform a fellow eye comparison of outcomes and complications when using air or sulfur hexafluoride (SF6) gas as a tamponade in Descemet membrane endothelial keratoplasty (DMEK). One hundred thirty-six eyes of 68 consecutive patients who underwent uneventful DMEK in both eyes for Fuchs endothelial corneal dystrophy were included in this retrospective study. Inclusion criteria were air tamponade (80% of the anterior chamber volume) in the first eye and 20% SF6 gas tamponade (80% of the anterior chamber volume) in the second eye; and same donor tissue culture condition in both eyes. All eyes received laser iridotomy on the day before DMEK. Main outcome measures included preoperative and postoperative best-corrected visual acuity, endothelial cell density, corneal volume, rebubbling rate, and rate of postoperative pupillary block caused by the air/gas bubble. Thirteen of 68 eyes (19.1%) with an air tamponade needed rebubbling compared with 4 of 68 eyes (5.9%) with an SF6 gas tamponade (P = 0.036). Postoperative pupillary block necessitating partial release of air/gas occurred in 1 eye (1.5%) with an air tamponade and 3 eyes (4.4%) with an SF6 gas tamponade (P = 0.301). There were no significant differences in preoperative and postoperative best-corrected visual acuity, endothelial cell density, and corneal volume within 3-month follow-up. Our results confirm the previously reported better graft adhesion when using an SF6 gas tamponade in DMEK without increased endothelial cell toxicity. The rate of pupillary block in eyes with an SF6 gas tamponade was comparable to that with an air tamponade. As a consequence, we recommend using SF6 gas as the tamponade in DMEK.

    To evaluate the use of computed tomography (CT) in the diagnosis of pericardial heart disease, 53 patients were prospectively studied by computed tomography of the chest and cardiac ultrasound. A diagnostic-quality CT study was done for all patients; a technically satisfactory ultrasound examination was not possible in six patients. Of 47 patients in whom both chest scans and satisfactory ultrasound studies were obtained, computed tomography showed pericardial thickening not shown by ultrasound in five patients. Estimated size of pericardial effusion was the same for both computed tomography and ultrasound. Computed tomography provided quantifiable evaluation of the composition of pericardial fluid in seven patients with either hemopericardium or purulent pericarditis. Neoplastic pericardial heart disease was detected by CT scan in four of the 53 patients. Computed tomography of the chest provides a sensitive evaluation of the pericardium and quality of pericardial effusion, and is a valuable adjunct in patients in whom cardiac ultrasound is technically unsatisfactory

    To examine the value of late-enhancement cardiac magnetic resonance imaging (MRI) for detection of pericardial inflammation. Late-enhancement cardiac MRI was performed in 16 patients with clinical suspicion of pericardial disease. Pericardial effusion, pericardial thickening and pericardial enhancement were assessed. MRI findings were compared with those of definitive pericardial histology (n=14) or microbiology (n=2). A control group of 12 patients with no clinical evidence of pericardial disease were also imaged with the same MRI protocol. Sensitivity and specificity for late-enhancement MRI detection of pericardial inflammation was of 100%. There was MRI late enhancement of the pericardial layers in all five patients with histological/microbiological evidence of inflammatory pericarditis. MRI demonstrated no pericardial thickening and no MRI late enhancement with or without a pericardial effusion in any of the five patients with histological evidence of a normal pericardium. MRI detected pericardial thickening in the absence of both pericardial effusion and late enhancement in all six patients with histological evidence of chronic fibrosing pericarditis. The 12 control subjects showed no evidence of pericardial MRI late enhancement. These findings demonstrate that MRI late enhancement can be used to visualize pericardial inflammation in patients with clinical suspicion of pericardial disease. (orig.)

    Catheter-associated bloodstream infection is highly prevalent and often associated with fatal complications. Some studies have shown that applying preventive interventions could help to reduce and control this type of infection. To determine whether a new consensus protocol for the manipulation and maintenance of central venous catheters would decrease catheter-associated bloodstream infections (CA-BSIs) in paediatric patients. To evaluate its compliance in intensive care units. Prospective study in the paediatric (PICU) and neonatal (NICU) intensive cares units, haematology, oncology and hospital wards in a Maternal and Paediatric reference Hospital in Barcelona. The study period is divided into two periods: before (first semester) and after the start of the new protocol (second semester) in 2007. The most important changes have been the insertion of the hermetic connection in the proximal and distal site (between the line and the syringe) of the central venous catheter (CVC), the labelling of the medication line and the CVC with the date of placement. A check-list to evaluate compliance was introduced in both intensive care units (paediatrics and neonatal) during the second study period. The rates of bloodstream infection per 1000 catheter-days were assessed. The rate of bloodstream infections per 1000 catheter-days before and after the start of the new protocol was 5.7 and 4.9 in PICU; 24.6 and 18.0 in NICU; 7.6 and 4.6 in haematology-oncology, and 11.9 and 10.3 in hospital wards. As regards compliance to the protocol, we found that proximal sealed connectors were used in more than 95% of the cases and up to 85% of the central venous catheter were labelled with the insertion date in both intensive care units. A consensus protocol for the use and maintenance of central venous catheters and healthcare worker training helped to control the rate of CA-BSIs. We reaffirm the importance of epidemiological surveillance as a measure for controlling nosocomial infections.

    Full Text Available Abstract Introduction Recurrent hemorrhagic pericardial effusion in children with no identifiable cause is a rare presentation. Case presentation We report the case of a 4-year-old Indian girl who presented with recurrent hemorrhagic pericardial effusion. Diffuse lymphangiomatosis was suspected when associated pulmonary involvement, soft tissue mediastinal mass, and lytic bone lesions were found. Pericardiectomy and lung biopsy confirmed the diagnosis of diffuse lymphangiohemangiomatosis. Partial clinical improvement occurred with thalidomide and low-dose radiotherapy, but our patient died from progressive respiratory failure. Conclusion Diffuse lymphangiohemangiomatosis should be considered in the differential diagnosis of hemorrhagic pericardial effusion of unclear cause.

    Pericardial fat necrosis is an infrequent cause of acute chest pain and this can mimic acute myocardial infarction and acute pericarditis. We describe here a patient with the magnetic resonance imaging (MRI) findings of pericardial fat necrosis and this was correlated with the computed tomography (CT) findings. The MRI findings may be helpful for distinguishing pericardial fat necrosis from other causes of acute chest pain and from the fat-containing tumors in the cardiophrenic space of the anterior mediastinum.

    Meigs' syndrome is defined as the presence of a benign ovarian tumor with pleural effusion and ascites that resolve after removal of the tumor. The pathogenesis of the production of ascites and pleural effusion in this syndrome remains unknown. Aside from pleural effusion and ascites, pericardial effusion is rarely observed in Meigs' syndrome. Here, we report the first case of Meigs' syndrome with preceding pericardial effusion in advance of pleural effusion. An 84-year-old Japanese non-smoking woman with a history of lung cancer, treated by surgery, was admitted due to gradual worsening of dyspnea that had occurred over the previous month. She had asymptomatic and unchanging pericardial effusion and a pelvic mass, which had been detected 3 and 11 years previously, respectively. The patient was radiologically followed-up without the need for treatment. Two months before admission, the patient underwent a right upper lobectomy for localized lung adenocarcinoma and intraoperative pericardial fenestration confirmed that the pericardial effusion was not malignant. However, she began to experience dyspnea on exertion leading to admission. A chest, abdomen, and pelvis computed tomography scan confirmed the presence of right-sided pleural and pericardial effusion and ascites with a left ovarian mass. Repeated thoracentesis produced cultures that were negative for any microorganism and no malignant cells were detected in the pleural effusions. Pleural fluid accumulation persisted despite a tube thoracostomy for pleural effusion drainage. With a suspicion of Meigs' syndrome, the patient underwent surgical resection of the ovarian mass and histopathological examination of the resected mass showed ovarian fibroma. Pleural and pericardial effusion as well as ascites resolved after tumor resection, confirming a diagnosis of Meigs' syndrome. This clinical course suggests a strong association between pericardial effusion and ovarian fibroma, as well as pleural and peritoneal

    Many types of cardiac and pericardial calcifications identified on chest radiographs can be recognized and distinguished based on characteristic locations and appearances. The purpose of this review is to emphasize the importance of detecting cardiac and pericardial calcifications on chest radiographs, and to illustrate and describe the various types of calcifications that may be encountered and how they may be differentiated from one another. Each type of cardiac and pericardial calcification is discussed, its location and appearance described, and its significance explained. Recognizing and understanding these calcifications is important as they are often encountered in daily practice and play an important role in patient care.

    Guidelines have been published for prevention of phlebitis associated with peripheral intravenous catheters (IVC), but this complication continues to occur. We sought to determine the rate of phlebitis associated with peripheral IVCs to identify predictors for phlebitis and to isolate pathogenic bacteria from phlebitic catheter tips. Nine-point prevalence studies were conducted during the years 1996-2003 of all hospitalized patients with a peripheral IVC. During the last 3 surveys, conducted in 2003, phlebitic lines were removed, and, for each line, 1 to 2 nonphlebitic lines, in place for 48 to 72 hours, were removed and cultured as controls. In between these surveys, findings and guidelines for improvement were distributed to the staff. During these surveys, 40% +/- 8% of hospitalized patients had a peripheral IVC. The rate of peripheral IVC-associated phlebitis decreased from 12.7% (20/157) in 1998 to 2.6% (5/189) in 2003 (P phlebitis included pain (P phlebitis associated with peripheral intravenous catheters decreased significantly throughout the study period. The identification of predictors for phlebitis and the dissemination of this information in an educational drive may have contributed to this improvement.

    Full Text Available Purulent pericarditis caused by Morganella morganii is extremely rare. We report herein a case of a 61-year-old man who presented with chest pain and dyspnea fourteen days after chemotherapy for multiple myeloma. Echocardiogram and computed tomography revealed a massive pericardial effusion and associated cardiac tamponade. Pericardiocentesis was performed. Pericardial fluid was found to be purulent, and Morganella morganii was isolated from the fluid. The patient was successfully treated with antibiotic therapy and surgical drainage of the fluid. Morganella morganii should be considered a possible pathogen when immunocompromised patients develop purulent pericarditis.

    To determine the incidence of catheter-related infection in patients with pulmonary arterial hypertension (PAH) receiving epoprostenol (EPO), and to note an etiologic role for Micrococcus spp, which is rarely reported as a pathogen in the medical literature. Observational study. Two PAH specialty treatment centers, Harbor-UCLA Medical Center (Torrance, CA), and the College of Physicians and Surgeons, Columbia University (New York, NY). A total of 192 patients with PAH receiving continuous therapy with IV EPO. From 1987 to 2000, 192 patients with PAH received infusions of EPO via central venous catheter. Catheter care included regular dressing changes with dry gauze using a sterile procedure, without the use of flushes. Patients were asked to report on known infections and treatments, and symptoms. All infections were verified by a telephone call to the patient, care provider, and microbiology laboratory whenever possible. There were 335,285 catheter days (mean +/- SD, 1,325 +/- 974 catheter days). There were 88 clinical catheter infections with 51 blood culture-positive infections, necessitating catheter removal in 38 instances. The following pathogens were isolated: Staphylococcus aureus (25); Micrococcus spp (14); mixed flora (3); coagulase-negative Staphylococcus spp (2); Corynebacterium spp (2); Serratia marcessens (1); Enterobacter spp (1); Pseudomonas aeruginosa (1); enterococci (1); and unidentified Gram-positive cocci (1). The catheter infection rate was 0.26 per 1,000 catheter days. The use of long-term therapy with continuous EPO appears to be associated with a low incidence of catheter-related infections. Micrococcus spp were the second most common etiologic agent. Caregivers managing patients with PAH must be aware of the risk of catheter infection, as it may contribute to the morbidity and mortality associated with the use of EPO. When isolated, Micrococcus spp should not be viewed as a contaminant, but rather as a true pathogen that may require

  8. Acute tamponade alters subendo- and subepicardial pressure-flow relations differently during vasodilation.

    1994-07-01

    Instantaneous diastolic left coronary artery pressure-flow relations (PFR) shift during acute tamponade as pressure surrounding the heart increases. Coronary pressure at zero flow (Pf = 0) on the linear portion of the PFR is the weighted mean of the different myocardial waterfall pressures, the distribution of which varies across the left ventricular wall during diastole. However, instantaneous PFR measured in large epicardial coronary arteries cannot be used to estimate Pf = 0 in the different myocardial tissue layers. During coronary vasodilatation in a capacitance-free model, myocardial PFR differs from subendocardium to subepicardium. Therefore, we studied the effects of acute tamponade during maximal pharmacology induced coronary vasodilatation on myocardial PFR in in situ anesthetized dogs. Tamponade reduced cardiac output, aortic pressure, and coronary blood flow. Results demonstrate that different mechanisms influence distribution of myocardial blood flow during tamponade. Subepicardial vascular resistance is unchanged and the extrapolated Pf = 0 is increased, thereby shifting PFR to a higher intercept on the pressure axis. Subendocardial vascular resistance is increased while the extrapolated Pf = 0 remains unchanged. Results indicate that in the setting of acute tamponade with coronary vasodilatation different mechanisms regulate the distribution of myocardial blood flow: in the subepicardium only outflow pressure increases, whereas in the subendocardium only vascular resistance increases.

    Full Text Available Ross W McQuivey,1 Jon E Block,2 Robert A Massaro3 1Clinical Innovations, Salt Lake City, UT, USA; 2Independent Clinical Consultant, San Francisco, CA, USA; 3Monmouth Medical Center, Long Branch, NJ, USA Abstract: As a leading cause of maternal death, postpartum hemorrhage (PPH remains a worldwide obstetrical problem. However, in most cases, mortality and morbidity can be averted if efforts are immediately undertaken to achieve hemostasis. Uterine balloon tamponade has been shown to provide effective control of PPH and avoid more invasive surgical procedures and even the emergency peripartum hysterectomy. Recent clinical recommendation suggests that balloon tamponade should be considered earlier in the treatment cascade in conjunction with uterotonic agents to ensure hemostasis in the most timely fashion and maximize clinical outcomes. This paper profiles the ebb® Complete Tamponade System, a unique dual-balloon single-use device that was developed specifically for hemostatic management of PPH. The ebb system combines a uterine conforming balloon that can be rapidly deployed with a vaginal balloon that eliminates the need for vaginal packing. The description, indications for use, procedural steps, and clinical characterization of this device are presented. Keywords: postpartum hemorrhage, balloon tamponade, hemostasis, maternal bleeding

    Full Text Available Cardiac tamponade is a state of constriction of the heart with an excessive fluid or hematoma resulted from various conditions. Postoperative tamponade can occur after coronary bypass surgery. Despite it is uncommon, its results may have a high risk of mortality and morbidity. Acute postoperative cardiac tamponade reveals a vast spectrum of symptoms. Moreover, a compression over the saphenous vein graft is the worst complication that should be managed without delay. We report a rare case of saphenous vein graft failure due to the cardiac tamponade following a coronary surgery and its management with a practical measure.

    Essentials It is unclear if thrombophilia increases the risk of catheter-associated thrombosis in children. We conducted a meta-analysis on thrombophilia and pediatric catheter-associated thrombosis. Presence of ≥1 trait confers additional risk of venous thrombosis in children with catheters. Limitations of included studies preclude us from recommending routine thrombophilia testing. Background The association between thrombophilia and deep vein thrombosis (DVT) associated with central venous catheter (CVC) use, the most important pediatric risk factor for thrombosis, is unclear in children. Pediatric studies with small sample sizes have reported conflicting results. We sought to evaluate whether, among children with CVCs, thrombophilia increases the risk of CVC-associated DVT (CADVT). Materials and methods We systematically searched MEDLINE, EMBASE, the Web of Science, the Cochrane Central Register for Controlled Trials, PubMed and reference lists for controlled studies published from the inception of the database until September 2015. Included were studies of children aged levels and the FV Leiden mutation had an increased prevalence of CADVT. The association with thrombophilia seemed to be stronger for symptomatic CADVT (pOR 6.71; 95% CI 1.93-23.37) than for asymptomatic CADVT (pOR 2.14; 95% CI 1.10-4.18). Conclusions On the basis of the low prevalence of specific traits, the relatively weak association with CADVT, and the limitations of the included studies, we cannot recommend routine testing of thrombophilias in children with CADVT. © 2016 International Society on Thrombosis and Haemostasis.

  12. Bacterial Biofilms and Catheters: A Key to Understanding Bacterial Strategies in Catheter-Associated Urinary Tract Infection

    Full Text Available Despite major technological improvements in catheter drainage systems, the indwelling Foley catheter remains the most common cause of nosocomial infection in medical practice. By approaching this common complicated urinary tract infection from the perspective of the biofilm strategy bacteria appear to use to overcome obstacles to produce bacteriuria, one appreciates a new understanding of these infections. An adherent biofilm of bacteria in their secretory products ascends the luminal and external surface of the catheter and drainage system from a contaminated drainage spigot or urethral meatus into the bladder. If the intraluminal route of bacterial ascent is delayed by strict sterile closed drainage or addition of internal modifications to the system, the extraluminal or urethral route assumes greater importance in the development of bacteriuria, but takes significantly longer. Bacterial growth within these thick coherent biofilms confers a large measure of relative resistance to antibiotics even though the individual bacterium remains sensitive, thus accounting for the failure of antibiotic therapy. With disruption of the protective mucous layer of the bladder by mechanical irritation, the bacteria colonizing the catheter can adhere to the bladder’s mucosal surface and cause infection. An appreciation of the role of bacterial biofilms in these infections should suggest future directions for research that may ultimately reduce the risk of catheter-associated infection.

    Full Text Available Abstract Background Traumatic hemopericardium remains a rare entity; it does however commonly cause cardiac tamponade which remains a major cause of death in traumatic blunt cardiac injury. Objectives We present a case of blunt chest trauma complicated by cardiac tamponade causing cardiac chamber equalization revealed by reflux of contrast. Case report A 29-year-old unidentified male suffered blunt chest trauma in a motor vehicle collision. Computed tomography (CT demonstrated a periaortic hematoma and hemopericardium. Significant contrast reflux was seen in the inferior vena cava and hepatic veins suggesting a change in cardiac chamber pressures. After intensive treatment including cardiac massage this patient expired of cardiac arrest. Conclusion Reflux of contrast on CT imaging can be an indicator of traumatic cardiac tamponade.

    Catheter-associated urinary tract infection (UTI) in nursing home residents is a common cause of sepsis, hospital admission, and antimicrobial use leading to colonization with multidrug-resistant organisms. To develop, implement, and evaluate an intervention to reduce catheter-associated UTI. A large-scale prospective implementation project was conducted in community-based nursing homes participating in the Agency for Healthcare Research and Quality Safety Program for Long-Term Care. Nursing homes across 48 states, Washington DC, and Puerto Rico participated. Implementation of the project was conducted between March 1, 2014, and August 31, 2016. The project was implemented over 12-month cohorts and included a technical bundle: catheter removal, aseptic insertion, using regular assessments, training for catheter care, and incontinence care planning, as well as a socioadaptive bundle emphasizing leadership, resident and family engagement, and effective communication. Urinary catheter use and catheter-associated UTI rates using National Healthcare Safety Network definitions were collected. Facility-level urine culture order rates were also obtained. Random-effects negative binomial regression models were used to examine changes in catheter-associated UTI, catheter utilization, and urine cultures and adjusted for covariates including ownership, bed size, provision of subacute care, 5-star rating, presence of an infection control committee, and an infection preventionist. In 4 cohorts over 30 months, 568 community-based nursing homes were recruited; 404 met inclusion criteria for analysis. The unadjusted catheter-associated UTI rates decreased from 6.78 to 2.63 infections per 1000 catheter-days. With use of the regression model and adjustment for facility characteristics, the rates decreased from 6.42 to 3.33 (incidence rate ratio [IRR], 0.46; 95% CI, 0.36-0.58; P project. Catheter utilization remained unchanged (4.50 at baseline, 4.45 at conclusion of project; IRR, 0

    Malignant pleural effusion can be recurrent despite active anti-cancer treatment. Significant malignant pleural effusion leads to debilitating dyspnoea and worsening quality of life in patients with advanced cancer. An indwelling pleural catheter offers a novel means to manage recurrent malignant pleural effusion and may remove the need for repeated thoracocentesis. Spontaneous pleurodesis is another unique advantage of indwelling pleural catheter placement but the factors associated with its occurrence are not clearly established. The aims of this study were to explore the safety of an indwelling pleural catheter in the management of symptomatic recurrent malignant pleural effusion, and to identify the factors associated with spontaneous pleurodesis. This case series with internal comparisons was conducted in the Division of Respiratory Medicine, Department of Medicine, Queen Mary Hospital, Hong Kong. All patients who underwent insertion of an indwelling pleural catheter from the initiation of such service from January 2010 to December 2014 were included for data analysis. Patients were monitored until December 2014, with the last catheter inserted in July 2014. Between 2010 and 2014, a total of 23 indwelling pleural catheters were inserted in 22 consecutive patients with malignant pleural effusion, including 15 (65.2%) cases with malignant pleural effusion as a result of metastatic lung cancer. Ten (43.5%) cases achieved minimal output according to defined criteria, in five of whom the pleural catheter was removed without subsequent re-accumulation of effusion (ie spontaneous pleurodesis). Factors associated with minimal output were the absence of trapped lung (P=0.036), shorter time from first appearance of malignant pleural effusion to catheter insertion (P=0.017), and longer time from catheter insertion till patient's death or end of study (P=0.007). An indwelling pleural catheter provides a safe means to manage symptomatic malignant pleural effusion

    Full Text Available Rumana N Hussain, Somnath BanerjeeLeicester Royal Infirmary, Leicester, UKIntroduction: Densiron® 68 is a high-density liquid used to tamponade inferior retinal detachments. We present a case series of 12 patients treated with Densiron as an intraocular tamponade agent.Methods: A retrospective analysis of 12 eyes in 12 patients was carried out. The primary endpoint was anatomic reattachment of the retina following removal of Densiron oil.Results: All patients had inferior detachments; 33% had associated proliferative vitreoretinopathy (PVR. Densiron was utilized as a primary agent in five patients (42%; the remaining patients had prior unsuccessful surgery for retinal reattachment, including pars plana vitrectomy, cryotherapy, laser, encirclement, gas (C3F8 or C2F6, or silicone oil. Eleven patients (91% had successful reattachment of the retina at 3 months following removal of Densiron; one patient had extensive PVR, total retinal detachment, preretinal macula fibrosis, and chronic hypotony, and surgical intervention was unsuccessful. Six patients (50% had raised intraocular pressure (IOP, resolving in the majority of cases following Densiron removal; two patients had long-term raised IOP requiring topical or surgical therapy. Of the six phakic patients, 50% developed significant cataract in the operated eye. Of those with successful retinal reattachment, visual outcome was variable, with 36% patients gaining two to four lines on Snellen, 27% remaining objectively the same, and 36% losing one to two lines.Conclusion: The anatomic success rate is high (91% in patients requiring Densiron tamponade for inferior retinal detachments with or without evidence of PVR either as a primary or secondary intervention. A common complication is raised IOP; however, this most often resolves following removal of the oil.Keywords: intraocular tamponade, silicone oil, retinal detachment, retinal reattachments

    MR examinations of 36 patients with pleural and/or pericardial effusions were retrospectively evaluated. The purpose of this study was to determine of MR imaging is capable of differentiating between pleural and pericardial effusions of different compositions using standard electrocardiogram (ECG)-gated and nongated spin echo pulse sequences. Additional data was obtained from experimental pleural effusions in 10 dogs. The results of this study indicate that old haemorhages into the pleural or pericardial space can be differentiated from other pleural or pericardial effusions. However, further differentiation between transudates, exudates and sanguinous effusions is not possible on MR images acquired with standard spin echo pulse sequences. (orig./MG)

    Full Text Available INTRODUCTION: Glutaraldehyde-treated crimped bovine pericardial grafts are currently used in aortic graft surgery. These conduits have become good options for these operations, available in different sizes and shapes and at a low cost. OBJECTIVE:To evaluate the results obtained with bovine pericardial grafts for aortic reconstruction, specially concerning late complications. METHOD: Between January 1995 and January 2002, 57 patients underwent different types of aortic reconstruction operations using bovine pericardial grafts. A total of 29 (50.8% were operated on an urgent basis (mostly acute Stanford A dissection and 28 electively. Thoracotomy was performed in three patients for descending aortic replacement (two patients and aortoplasty with a patch in one. All remaining 54 underwent sternotomy, cardiopulmonary bypass and aortic resection. Deep hypothermia and total circulatory arrest was used in acute dissections and arch operations. RESULTS: Hospital mortality was 17.5%. Follow-up was 24.09 months (18.5 to 29.8 months confidence interval and complication-free actuarial survival curve was 92.3% (standard deviation ± 10.6. Two patients lately developed thoracoabdominal aneurysms following previous DeBakey II dissection and one died from endocarditis. One "patch" aortoplasty patient developed local descending aortic pseudoaneurysm 42 months after surgery. All other patients are asymptomatic and currently clinically evaluated with echocardiography and CT scans, showing no complications. CONCLUSION: Use of bovine pericardial grafts in aortic reconstruction surgery is adequate and safe, with few complications related to the conduits.

    Malignant mesotheliomas are rather uncommon neoplasms associated primarily with asbestos exposure; however, they may also arise as second primary malignancies after radiation therapy, with a latency period of 15-25 years. Numerous studies have reported an association between pleural malignant mesothelioma and chest radiation performed for other malignancies; on the other hand, post-irradiation mesotheliomas of the pericardium have been reported in only a few published cases to date, and no homozygous deletion of 9p21 has been described in such cases. We report the case of a 48-year-old man with a history of Hodgkin's lymphoma and no prior asbestos exposure who developed pericardial malignant epithelioid mesothelioma. We further discuss the cytologic, histologic, immunophenotypic, and fluorescence in situ hybridization findings in this case. To our knowledge, this is the first well-documented case of post-radiation pericardial malignant mesothelioma showing homozygous deletion of 9p21. Homozygous deletion of 9p21, the locus harboring the p16 gene, is present in post-irradiation pericardial malignant mesothelioma.

    Prolonged catheterization is the primary risk factor for catheter-associated urinary tract infection (CAUTI). Reminder systems are interventions used to prompt the removal of unnecessary urinary catheters. To summarize the effect of urinary catheter reminder systems on the rate of CAUTI, urinary catheter use, and the need for recatheterization, we performed a systematic review and meta-analysis. Studies were identified in MEDLINE, the Cochrane Library, Biosis, the Web of Science, EMBASE, and CINAHL through August 2008. Only interventional studies that used reminders to physicians or nurses that a urinary catheter was in use or stop orders to prompt catheter removal in hospitalized adults were included. A total of 6679 citations were identified; 118 articles were reviewed, and 14 articles met the selection criteria. The rate of CAUTI (episodes per 1000 catheter-days) was reduced by 52% (P SMD) in the duration of catheterization was -1.11 overall (P = 070), including a statistically significant decrease in studies that used a stop order (SMD, -0.30; P = .001) but not in those that used a reminder (SMD, -1.54; P = .071). Recatheterization rates were similar in control and intervention groups. Urinary catheter reminders and stop orders appear to reduce the rate of CAUTI and should be strongly considered to enhance the safety of hospitalized patients.

    OBJECTIVES Mediastinal drainage following cardiac surgery with traditional large-bore plastic tubes can be painful and cumbersome. This study was designed to determine whether prolonged drainage (5 days) with a silastic tube decreased the incidence of significant pericardial effusion and tamponade following aortic or valvular surgery. METHODS One hundred and fifty patients undergoing valvular or aortic surgery in a tertiary cardiac surgery institution were randomized to receive a conventional mediastinal tube plus a silastic Blake drain (n = 75), or two conventional tubes (n = 75). Conventional drains were removed on postoperative day (POD) 1, while Blake drains were removed on POD 5. The primary end-point was the combined incidence of significant pericardial effusion (≥15 mm) or tamponade through POD 5. Secondary end-points included total mediastinal drainage, postoperative atrial fibrillation (AF) and pain. RESULTS Analysis was performed for 67 patients in the Blake group and 73 in the conventional group. There was no difference between the two groups in the combined end-point of significant effusion or tamponade (7.4 vs 8.3%, P = 0.74), or in the incidence of AF (47 vs 46%, P = 0.89). Mean 24-h drainage was greater in the Blake group than in the conventional group (749 ± 444 ml vs 645 ± 618 ml, P tubes is safe and does not increase postoperative pain. There was no difference between the Blake and conventional drains with regard to significant pericardial effusion or tamponade in this cohort; however, this conclusion is limited by the low overall incidence of the primary outcome in this cohort.

    Urinay tract infection (UTI) as one of the most frequent bacterial infections in humans is of utmost relevance. Because of the rising prevalence of antimicrobial resistance, urinalysis should always include urine culture and a resistogram in order to avoid an unspecific selection and overuse of antibiotics. Prevention of recurrent UTI must first of all rule out predisposing uropathogenic conditions. Nowadays, a great variety of drugs, behavioral, and supportive treatment options can effectively minimize UTI recurrence. The growing importance of vaccines (immunotherapy), probiotics (lactobacilli), and standardized herbal preparations meets the need of reducing antibiotic use and the development of antimicrobial resistance. Around 80% of all nosocomial UTIs (nUTIs) are associated with indwelling urinary catheters. It is estimated that up to 70% of all nUTIs occurring in Germany may be avoided by using appropriate preventative measures. Therefore, profound knowledge about the basics of catheter-associated nUTIs and the correct management of urinary catheters are of utmost individual and socioeconomic importance.

    A 75-year-old woman was discovered to have a pericardial effusion when she was admitted to our hospital because of a giant hepatic cyst. We could not detect the cause of the effusion and diagnosed idiopathic pericardial effusion. The patient underwent transcutaneous drainage of the hepatic cyst and an injection of antibiotics. There was no communication between the pericardial effusion and the hepatic cyst. Although the hepatic cyst was reduced in size, the pericardial effusion showed no remarkable change immediately after treatment; however, 5 months later, the pericardial effusion was found to be diminished. The pericardial effusion might have been caused by the physical pressure of the giant hepatic cyst and disturbance in the balance between the production and reabsorption of the pericardial fluid. When we experience a huge hepatic cyst, we should take into account its influence against the surrounding organs, including the intrapleural space.

    Catheter-associated urinary tract infections (CAUTIs) represent the most common type of nosocomial infection and are a major health concern due to the complications and frequent recurrence. These infections are often caused by Escherichia coli and Proteus mirabilis. Gram-negative bacterial species that cause CAUTIs express a number of virulence factors associated with adhesion, motility, biofilm formation, immunoavoidance, and nutrient acquisition as well as factors that cause damage to the host. These infections can be reduced by limiting catheter usage and ensuring that health care professionals correctly use closed-system Foley catheters. A number of novel approaches such as condom and suprapubic catheters, intermittent catheterization, new surfaces, catheters with antimicrobial agents, and probiotics have thus far met with limited success. While the diagnosis of symptomatic versus asymptomatic CAUTIs may be a contentious issue, it is generally agreed that once a catheterized patient is believed to have a symptomatic urinary tract infection, the catheter is removed if possible due to the high rate of relapse. Research focusing on the pathogenesis of CAUTIs will lead to a better understanding of the disease process and will subsequently lead to the development of new diagnosis, prevention, and treatment options.

    Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, pSMD) in catheterisation duration (days) was -1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD -0.37; pSMD, -1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits.

  10. Previous PICC Placement May Be Associated With Catheter-Related Infections in Hemodialysis Patients

    Butler, Philip J.; Sood, Shreya; Mojibian, Hamid; Tal, Michael G.

    2011-01-01

    Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History of PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71–3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.

    Objective: To evaluate the CT features and implications of the pericardial sinuses and recesses effusion by combining the sectional cadavers and 16 multi-slice CT (MSCT) reformation. Methods: The anatomy and communication of the pericardial sinuses and recesses on the axial, coronal and saggital sectional cadavers (respectively 1 case), and the morphologic features on MSCT reformatted images in 104 patients were observed. The detection rate of effusion was analyzed. Results: The sectional cadavers and CT images showed that the pericardial sinuses and recesses were formed by the reflections of the pericardium on the root of the great vessels. The detection rate of the sinuses and recesses was lower in small effusion than in moderate and large effusion (P<0.05). The superior aortic recess was the most common recess for pericardial effusion. Conclusion: The MSCT reformatted images can show the morphologic features of pericardial sinuses and recesses effusion and communications with the pericardial cavity, help differentiate pericardial effusion from other mediastinal or pericardial lesions.

    Tunneled dialysis catheters are the most common form of vascular access among incident dialysis patients in the United States. Fibrin sheath formation is a frequent cause of late catheter dysfunction requiring an exchange procedure with balloon disruption of the fibrin sheath. It is unknown whether fibrin sheath disruption is associated with increased incidence of bacteremia or catheter failure. We reviewed all tunneled dialysis catheter exchange procedures at the University of Wisconsin between January 2008 and December 2011. The primary outcome was incidence of bacteremia, defined as positive blood cultures within 2 weeks of the procedure. Catheter failure, requiring intervention or replacement, was examined as a secondary outcome. Baseline characteristics examined included diabetic status, gender, race and age. A total of 163 procedures were reviewed; 67 (41.1%) had fibrin sheath disruption and 96 did not. Bacteremia occurred in 4.5% (3/67) of those with and 3.1% (3/97) of those without fibrin sheath disruption (p=0.65). Fibrin sheath disruption was not significantly associated with the risk of catheter failure (adjusted hazard ratio [aHR]=1.34; 95% confidence interval [CI]: 0.87-2.10; p=0.18). Diabetes was associated with greater risk of catheter failure (aHR=1.88; 95% CI: 1.19-2.95; p=0.006), whereas higher age was associated with a lower risk of catheter failure (aHR per 10 years=0.83; 95% CI: 0.72-0.96; p=0.01). This study demonstrates that there is no significant increase in bacteremia and subsequent catheter dysfunction rates after fibrin sheath disruption compared to simple over the wire exchange. These results are encouraging given the large numbers of patients utilizing tunneled catheters for initial hemodialysis access and the known rates of fibrin sheath formation leading to catheter failure.

    Obesity is associated with increased risk of developing atrial fibrillation (AF). Different fat depots may have differential associations with cardiac pathology. We examined the longitudinal associations between pericardial, intrathoracic, and visceral fat with incident AF. We studied Framingham Heart Study Offspring and Third Generation Cohorts who participated in the multi-detector computed tomography sub-study examination 1. We constructed multivariable-adjusted Cox proportional hazard models for risk of incident AF. Body mass index (BMI) was included in the multivariable-adjusted model as a secondary adjustment. We included 2,135 participants (53.3% women; mean age 58.8 years). During a median follow-up of 9.7 years, we identified 162 cases of incident AF. Across the increasing tertiles of pericardial fat volume, age- and sex-adjusted incident AF rate per 1000 person-years of follow-up were 8.4, 7.5, and 10.2. Based on an age- and sex-adjusted model, greater pericardial fat [hazard ratio (HR) 1.17, 95% confidence interval (CI) 1.03-1.34] and intrathoracic fat (HR 1.24, 95% CI 1.06-1.45) were associated with increased risk of incident AF. The HRs (95% CI) for incident AF were 1.13 (0.99-1.30) for pericardial fat, 1.19 (1.01-1.40) for intrathoracic fat, and 1.09 (0.93-1.28) for abdominal visceral fat after multivariable adjustment. After additional adjustment of BMI, none of the associations remained significant (all p>0.05). Our findings suggest that cardiac ectopic fat depots may share common risk factors with AF, which may have led to a lack of independence in the association between pericardial fat with incident AF.

    The purpose of this study was to describe the appearance of pericardial effusion in deceased acute aortic dissection patients using postmortem computed tomography (PMCT). PMCT examinations were performed within 2 hours of death in 30 patients with pericardial effusion due to aortic dissection who arrived at our hospital in a state of cardiopulmonary arrest. Pericardial effusion in 18 of 30 patients (60%) showed double concentric rings on PMCT with striking differences in density, a low-density outer ring along the pericardium and a high-density inner ring on the epicardial surface (hyperdense armored heart). Pericardial effusion in two patients (7%) showed a high-density fluid level (hypostasis). Pericardial effusion in the remaining 10 patients (33%) showed no such stratification. A ''hyperdense armored heart'' is the most frequently seen PMCT finding in deceased cases of pericardial effusion due to acute aortic dissection. (author)

    Major depressive disorder (MDD) is associated with an increased risk for the development of cardio-metabolic diseases. Increased intra-abdominal (IAT) and pericardial adipose tissue (PAT) have been found in depression, and are discussed as potential mediating factors. IAT and PAT are thought to be the result of a dysregulation of the hypothalamus-pituitary-adrenal axis (HPAA) with subsequent hypercortisolism. Therefore we examined adrenal gland volume as proxy marker for HPAA activation, and IAT and PAT in depressed patients. Twenty-seven depressed patients and 19 comparison subjects were included in this case-control study. Adrenal gland volume, pericardial, intraabdominal and subcutaneous adipose tissue were measured by magnetic resonance imaging. Further parameters included factors of the metabolic syndrome, fasting cortisol, fasting insulin, and proinflammatory cytokines. Adrenal gland and pericardial adipose tissue volumes, serum concentrations of cortisol and insulin, and serum concentrations tumor-necrosis factor-α were increased in depressed patients. Adrenal gland volume was positively correlated with intra-abdominal and pericardial adipose tissue, but not with subcutaneous adipose tissue. Our findings point to the role of HPAA dysregulation and hypercortisolism as potential mediators of IAT and PAT enlargement. Further studies are warranted to examine whether certain subtypes of depression are more prone to cardio-metabolic diseases. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Preventing catheter-associated urinary tract infections is in the forefront of health care quality. However, nurse and physician engagement is a common barrier in infection prevention efforts. After implementation of a multidisciplinary catheter-associated urinary tract infection (CAUTI) prevention campaign, we studied the impact of our campaign and showed its association with reducing the CAUTI rate and catheter utilization and the positive effect on health care workers' engagement and perspectives. CAUTI prevention campaigns can lead to lower infection rates and change health care workers' perspective. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

    Healthcare associated infections from indwelling urinary catheters lead to increased patient morbidity and mortality. The purpose of this study was to determine if direct observation of the urinary catheter insertion procedure, as compared to the standard process, decreased catheter utilization and urinary tract infection rates. This case control study was conducted in a medical intensive care unit. During phase I, a retrospective data review was conducted on utilsiation and urinary catheter infection rates when practitioners followed the institution's standard insertion algorithm. During phase II, an intervention of direct observation was added to the standard insertion procedure. The results demonstrated no change in utilization rates, however, CAUTI rates decreased from 2.24 to 0 per 1000 catheter days. The findings from this study may promote changes in clinical practice guidelines leading to a reduction in urinary catheter utilization and infection rates and improved patient outcomes.

    Postpartum haemorrhage is one of the major causes of maternal mortality worldwide. The leading cause of primary postpartum haemorrhage is uterine atony and active management of the third stage of labour with oxytocin is recommended for preventing primary postpartum haemorrhage. Parenteral oxytocin is also the drug of choice for medical management of postpartum haemorrhage secondary to uterine atony. Condom uterine balloon tamponade is .a low cost technique that can be used as a second-line option for treatment. We report retrospectively three cases of primary PPH secondary to uterine atony which were managed successfully with condom tamponade. Condom tamponade is effective in managing post partum haemorrhage secondary to uterine atony and we advocate for the training of all skilled attendants on how to insert the condom tamponade.

    The purpose of this study was to establish, using computed tomography, the normal thickness of the pericardium in adults. Materials and Methods: CT scans of 50 patients, including sections through the level of the heart, were reviewed. Patients were excluded if there were any suspicions of pericardial abnormality such as infectious or neoplastic diseases. Twenty-four of the 50 were men and 26 were women; their mean age was 47.0(range,18-76) years. We measured pericardial thickness at the level of the right ventricle, interventricular septum and left ventricle, and also compared pericardial thickness in terms of age and sex. Results: In all patients, the pericardium was observed in the right ventricular region; in 41 (82%) at the interventricular septum; and in 41 (82%) along the left ventricle. The mean thickness of normal pericardium at the level of the right ventricle, interventricular septum, and left ventricle was 1.8 mm ± 0.5 mm, 1.8 mm ± 0.4 mm, and 1.7 mm ± 0.5 mm, respectively. No statistically significant correlation was apparent between pericardial thickness and age group (p > 0.63, ANOVA test). Mean pericardial thickness was 1.9 mm ± 0.6 mm in males and 1.7 mm ± 0.4 mm in females; thus, no statistically significant correlation was apparent between pericardial thickness and sex (p >0.29, Student's t-test). Conclusion: The pericardium was best visualized in sections through the right ventricle.The mean thickness of normal pericardium was 1.8 mm ± 0.5 mm and pericardial thickness did not differ according to age or sex

    Full Text Available Endocarditis associated with dialysis catheter is a disease that must be suspected in every patient with hemodialysis who develops fever. Multiple valve disease is a severe complication of endocarditis that needs to be managed in a different way. There is very limited data for treatment and every case must be considered individually. We present a patient with this complication and describe the medical treatment and surgical management. We report the case of a 15-year-old patient with acute renal failure that develops trivalvular endocarditis after the hemodialysis catheter was placed, with multiple positive blood culture for Staphylococcus aureus. Transesophageal echocardiography was done and aortic and tricuspid valvular vegetations and mitral insufficiency were reported. Patient was successfully treated by surgery on the three valves, including aortic valve replacement. There is limited data about the appropriate treatment for multiple valvular endocarditis; it is important to consider this complication in the setting of hemodialysis patients that develop endocarditis and, despite the appropriate treatment, have a torpid evolution. In countries where endovenous drug abuse is uncommon, right sided endocarditis is commonly associated with vascular catheters. Aggressive surgical management should be the treatment of choice in these kinds of patients.

    Background Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. Methods To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. Results 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, p<0.001) using a reminder or stop order, with five studies also including interventions to decrease initial UC placement. The pooled (nine studies) standardised mean difference (SMD) in catheterisation duration (days) was −1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD −0.37; p<0.001) but not in reminder studies (SMD, −1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. Conclusions UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits. PMID:24077850

    The most common source of nosocomial infection is the urinary tract, especially if they it is drained with a urethral catheter. Catheter-associated urinary tract infections account for at least 80% of all complicated urinary tract infections and are the most common type of hospital-acquired infection. Intestinal microflora plays the leading role in the pathogenesis of catheter-associated urinary tract infections, whereas the most important risk factor for their development is the long duration of urinary catheter drainage. In the case of short-term and intermittent catheterization, routine antibiotic prophylaxis is not required, but if a patient develops clinically significant infection, antibiotic therapy is required followed by definitive therapy based on culture. Urethral catheters coated with antimicrobial substances and anti-inflammatory agents can significantly reduce the adhesion and migration of bacteria, thereby reducing the incidence of urinary tract infections. Despite this, the incidence of catheter-associated infection remains high. We have reviewed recent literature related to catheter-associated urinary tract infections and the best means of preventing this condition.

    In an attempt to overcome infections associated with central venous catheters, a new antiseptic central venous catheter coated with benzalkonium chloride on the internal and external surfaces has been developed and evaluated in a clinical trial. Patients (235) randomly received either a triple-lumen central venous catheter coated with benzalkonium chloride (117) or a polyurethane non-antiseptic catheter (118). The incidence of microbial colonization of both catheters and retained antiseptic activity of the benzalkonium chloride device following removal were determined. The benzalkonium chloride resulted in a significant reduction of the incidence of microbial colonization on both the internal and external catheter surfaces. The reduction in colonization was detected at both the intradermal (21 benzalkonium chloride catheters vs. 38 controls, P = 0.0016) and distal segments of the antiseptic-coated catheters. Following catheter removal retained activity was demonstrated in benzalkonium chloride catheters which had been in place for up to 12 days. No patients developed adverse reactions to the benzalkonium chloride catheters. The findings demonstrate that the benzalkonium chloride catheter significantly reduced the incidence of catheter-associated colonization.

    Full Text Available Abstract Introduction Congenital pericardial cysts are benign lesions that arise from the pericardium during embryonic development. The diagnosis is based on typical imaging features, but atypical locations and signal magnetic resonance imaging sequences make it difficult to exclude other lesions. Diffusion-weighted magnetic resonance imaging is a novel method that can be used to differentiate tissues based on their restriction to proton diffusion. Its use in differentiating pericardial cysts from other pericardial lesions has not yet been described. Case presentation We present three cases (a 51-year-old Caucasian woman, a 66-year-old Caucasian woman and a 77-year-old Caucasian woman with pericardial cysts evaluated with diffusion-weighted imaging using cardiac magnetic resonance imaging. Each lesion demonstrated a high apparent diffusion coefficient similar to that of free water. Conclusion This case series is the first attempt to investigate the utility of diffusion-weighted magnetic resonance imaging in the assessment of pericardial cysts. Diffusion-weighted imaging may be a useful noninvasive diagnostic tool for pericardial cysts when conventional imaging findings are inconclusive.

    Indwelling urinary catheters (IUCs) are commonly used in hospitalized patients, especially elders. Catheter-associated urinary tract infections (CAUTIs) account for 34% of all health care associated infections in the United States, associated with excess morbidity and health care costs. Adherence to CAUTI prevention practices has not been well described. This study used an electronic survey to examine IUC care practices for CAUTI prevention in 3 areas-(1) equipment and alternatives and insertion and maintenance techniques; (2) personnel, policies, training, and education; and (3) documentation, surveillance, and removal reminders-at 75 acute care hospitals in the Nurses Improving the Care of Healthsystem Elders (NICHE) system. CAUTI prevention practices commonly followed included wearing gloves (97%), handwashing (89%), maintaining a sterile barrier (81%), and using a no-touch insertion technique (73%). Silver-coated catheters were used to varying degrees in 59% of the hospitals; 4% reported never using a catheter-securing device. Urethral meatal care was provided daily by 43% of hospitals and more frequently that that by 41% of hospitals. Nurses were the most frequently reported IUC inserters. Training in aseptic technique and CAUTI prevention at the time of initial nursing hire was provided by 64% of hospitals; however, only 47% annually validated competency in IUC insertion. Systems for IUC removal were implemented in 56% of hospitals. IUC documentation and routine CAUTI surveillance practices varied widely. Although many CAUTI prevention practices at NICHE hospitals are in alignment with evidence-based guidelines, there is room for improvement. Further research is needed to identify the effect of enhanced compliance with CAUTI prevention practices on the prevalence of CAUTI in NICHE hospitals.

    Fadi Al Akhrass

    Full Text Available Rhodococcus is an emerging cause of opportunistic infection in immunocompromised patients, most commonly causing cavitary pneumonia. It has rarely been reported as a cause of isolated bacteremia. However, the relationship between bacteremia and central venous catheter is unknown. Between 2002 and 2010, the characteristics and outcomes of seventeen cancer patients with Rhodococcus bacteremia and indwelling central venous catheters were evaluated. Rhodococcus bacteremias were for the most part (94% central line-associated bloodstream infection (CLABSI. Most of the bacteremia isolates were Rhodococcus equi (82%. Rhodococcus isolates formed heavy microbial biofilm on the surface of polyurethane catheters, which was reduced completely or partially by antimicrobial lock solution. All CLABSI patients had successful response to catheter removal and antimicrobial therapy. Rhodococcus species should be added to the list of biofilm forming organisms in immunocompromised hosts and most of the Rhodococcus bacteremias in cancer patients are central line associated.

    The Biosense Webster ThermoCool® SmartTouch® Surround Flow (STSF) catheter is a recently developed ablation catheter incorporating Surround Flow (SF) technology to ensure efficient cooling and force sensing to quantify tissue contact. In our unit, it superseded the ThermoCool® SF catheter from the time of its introduction in May 2015. Procedure-related data were collected prospectively for the first 100 ablation procedures performed in our department using the STSF catheter. From a database of 654 procedures performed in our unit using the SF catheter, we selected one to match each STSF procedure, matching for procedure type, operator experience, patient age, and gender. The groups were well matched for patient age, gender, and procedure type. Procedure duration was similar in both groups (mean 225.5 vs. 221.4 min, IQR 106.5 vs. 91.5, P = 0.55), but fluoroscopy duration was shorter in the STSF group (mean 25.8 vs. 30.0, IQR 19.6 vs. 18.5, P = 0.03). No complication occurred in the STSF group. Complications occurred in two cases in the SF group (one pericardial effusion requiring drainage and one need for permanent pacing). Complete procedural success was achieved in 98 cases in the STSF group and 94 cases in the SF group (P = 0.15). The composite endpoint of procedure failure or acute complication was less common in the STSF group (2 vs. 8, P = 0.05). The STSF catheter is safe and effective in treating a range of arrhythmias. Compared with the SF catheter, it shows a trend towards improved safety-efficacy balance. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2016.

    Full Text Available Aim. Postoperative atrial fibrillation is one of the most frequent complications in cardiac surgery. The aim of this trial was to evaluate the effectiveness of posterior pericardiotomy in the prevention of postoperative atrial fibrillation and pericardial effusion in patients undergoing isolated primary aortic valve replacement.Methods. The trial was approved by the local ethics committee. It included adult patients under 70 y.o. who had signed the informed consent for participation in the study and who were planned to undergo isolated primary aortic valve replacement. Exclusion criteria were a history of atrial fibrillation, hyperthyroidism, amiodarone intake, severe chronic obstructive pulmonary disease, left ventricle ejection fraction less than 30%, the size of the left atrium exceeding 50 mm, active infective endocarditis, the presence of adhesions in the pericardium and/or left pleural cavity and mini-sternotomy. From October 2013 to April 2015 607 patients in our clinic underwent different aortic valve procedures. 507 patients were excluded from the study because of the inclusion and exclusion criteria. The remaining 100 patients were randomized into two groups: 49 patients underwent posterior pericardiotomy and 51 patients made up the control group. In both groups the frequency of postoperative atrial fibrillation, pericardial effusion greater than 5 mm, surgery-discharge time, as well as posterior-pericardiotomy-related complications were studied. Trial number: ISRCTN11129539.Results. There were no deaths, stroke or cardiac tamponade during the postoperative stay. Neither were there any complications associated with the performance of posterior pericardiotomy. The incidence of atrial fibrillation, pericardial effusion and average duration of the postoperative stay were similar in both groups: 16% in posterior pericardiotomy group vs 14% in the control group (p=0.71, 10% in posterior pericardiotomy group vs 12% in the control group (p=0

  17. Virulence factors in Proteus bacteria from biofilm communities of catheter-associated urinary tract infections.

    2012-07-01

    More than 40% of nosocomial infections are those of the urinary tract, most of these occurring in catheterized patients. Bacterial colonization of the urinary tract and catheters results not only in infection, but also various complications, such as blockage of catheters with crystalline deposits of bacterial origin, generation of gravels and pyelonephritis. The diversity of the biofilm microbial community increases with duration of catheter emplacement. One of the most important pathogens in this regard is Proteus mirabilis. The aims of this study were to identify and assess particular virulence factors present in catheter-associated urinary tract infection (CAUTI) isolates, their correlation and linkages: three types of motility (swarming, swimming and twitching), the ability to swarm over urinary catheters, biofilm production in two types of media, urease production and adherence of bacterial cells to various types of urinary tract catheters. We examined 102 CAUTI isolates and 50 isolates taken from stool samples of healthy people. Among the microorganisms isolated from urinary catheters, significant differences were found in biofilm-forming ability and the swarming motility. In comparison with the control group, the microorganisms isolated from urinary catheters showed a wider spectrum of virulence factors. The virulence factors (twitching motility, swimming motility, swarming over various types of catheters and biofilm formation) were also more intensively expressed. © 2012 Federation of European Microbiological Societies.

    Post-mortem cardiac MR exams present with different contraction appearances of the left ventricle in cardiac short axis images. It was hypothesized that the grade of post-mortem contraction may be related to the post-mortem interval (PMI) or cause of death and a phenomenon caused by internal rigor mortis that may give further insights in the circumstances of death. The cardiac contraction grade was investigated in 71 post-mortem cardiac MR exams (mean age at death 52 y, range 12-89 y; 48 males, 23 females). In cardiac short axis images the left ventricular lumen volume as well as the left ventricular myocardial volume were assessed by manual segmentation. The quotient of both (LVQ) represents the grade of myocardial contraction. LVQ was correlated to the PMI, sex, age, cardiac weight, body mass and height, cause of death and pericardial tamponade when present. In cardiac causes of death a separate correlation was investigated for acute myocardial infarction cases and arrhythmic deaths. LVQ values ranged from 1.99 (maximum dilatation) to 42.91 (maximum contraction) with a mean of 15.13. LVQ decreased slightly with increasing PMI, however without significant correlation. Pericardial tamponade positively correlated with higher LVQ values. Variables such as sex, age, body mass and height, cardiac weight and cause of death did not correlate with LVQ values. There was no difference in LVQ values for myocardial infarction without tamponade and arrhythmic deaths. Based on the observation in our investigated cases, the phenomenon of post-mortem myocardial contraction cannot be explained by the influence of the investigated variables, except for pericardial tamponade cases. Further research addressing post-mortem myocardial contraction has to focus on other, less obvious factors, which may influence the early post-mortem phase too. Copyright © 2015 Elsevier Ireland Ltd.

    Intravenous catheters have been indispensable tools of modern medicine. Although intravenous applications can be used for a multitude of purposes, these applications may cause complications, some of which have serious effects. Of these complications, the most commonly observed is phlebitis. This study was conducted to determine the effect of catheter indwell time on phlebitis development during peripheral intravenous catheter administration. This study determined the effect of catheter indwell time on phlebitis development during peripheral intravenous catheter administration. The study included a total of 103 individuals who were administered 439 catheters and satisfied the study enrollment criteria at one infectious diseases clinic in Istanbul/Turkey. Data were compiled from Patient Information Forms, Peripheral Intravenous Catheter and Therapy Information Forms, reported grades based on the Visual Infusion Phlebitis Assessment Scale, and Peripheral Intravenous Catheter Nurse Observation Forms. The data were analyzed using SPSS. Results : The mean patient age was 53.75±15.54 (standard deviation) years, and 59.2% of the study participants were men. Phlebitis was detected in 41.2% of peripheral intravenous catheters, and the rate decreased with increased catheter indwell time. Analyses showed that catheter indwell time, antibiotic usage, sex, and catheterization sites were significantly associated with development of phlebitis. The results of this study show that catheters can be used for longer periods of time when administered under optimal conditions and with appropriate surveillance.

    To insert a tube into pericardial cavity as an emergent measure of diagnosis and treatment in patients with malignant pericardial effusion. Pericardial puncture was followed by insertion of drainage tube (diameter = 1.8 mm) through the puncture needle. The effusion collected was examined for cancer cells. After drainage, chemotherapeutic agents were administered. Four hours later, drainage was continued for 2 days (drained in 24 hr) and the tube was removed. In 34 cases with malignant pericardial effusion, tube draining was successful to relieve cardiac temponade within 15-60 minutes. Clots were present in 91.2% of the cases and cancer diagnosis was confirmed in all of them. The cytologic diagnosis of effusion was positive in 61.8%, and the cyto-pathologic typing of clots was 81.0%. The difference was statistically significant. When the results of the 2 examinations were put together, the positive rate increased to 94.1%. Tube drainage of malignant pericardial effusion is useful in diagnosis and emergency treatment.

    Pericardial effusion is common in hospitalized patients with chronic kidney disease (CKD). We sought to identify predictors of pericardial effusion in CKD patients and to evaluate the impact of pericardial effusion on their mortality and morbidity. In a retrospective nested case control study design, we analyzed hospitalized adult patients with CKD stage 4, 5, and end-stage renal disease (ESRD) diagnosed with pericardial effusion. Randomly selected patients with CKD stage 4, 5, and ESRD without pericardial effusion were used as controls. We analyzed 84 cases and 61 controls, of whom 44% and 34% were on dialysis, respectively. The mean blood urea nitrogen and creatinine were 70±27 mg/dL and 8.4±6.0 mg/dL among cases, 54±26 mg/dL and 6.0±3.4 mg/dL among controls, respectively. Effusion was moderate to large in 46% of cases. Predictors of any pericardial effusion were serum potassium (OR, 1.95 per 1 mEq/L increment in level; CI, 1.21-3.13; p=0.006), serum corrected calcium (OR, 1.33 per 1mg/dl decrement in level; CI, 1.11-1.67; p=0.015) and admission heart rate (OR, 1.29 per 10 beats/minute increment in heart rate; CI, 1.03-1.62; p=0.027). Corrected calcium level was an independent predictor of moderate to large pericardial effusion, (OR, 1.38 per 1 mg/dL decrement in level; CI, 1.04-1.82, p=0.023). Corrected calcium effusion. Patients with effusion had no significant difference in mortality or cardiovascular re-hospitalization (log-rank p=0.408). In hospitalized CKD patients, hypocalcemia may be useful in identifying those with moderate to large pericardial effusion. This article is protected by copyright. All rights reserved.

    To investigate whether cell-derived microparticles play a role in complement activation in pericardial blood of patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) and whether microparticles in pericardial blood contribute to systemic complement activation upon retransfusion. Pericardial blood of 13 patients was retransfused in 9 and discarded in 4 cases. Microparticles were isolated from systemic blood collected before anesthesia (T1) and at the end of CPB (T2), and from pericardial blood. The microparticles were analyzed by flow cytometry for bound complement components C1q, C4 and C3, and bound complement activator molecules C-reactive protein (CRP), serum amyloid P-component (SAP), immunoglobulin (Ig)M and IgG. Fluid-phase complement activation products (C4b/c, C3b/c) and activator molecules were determined by ELISA. Compared with systemic T1 blood, pericardial blood contained increased C4b/c and C3b/c, and increased levels of microparticles with bound complement components. In systemic T1 samples, microparticle-bound CRP, whereas in pericardial blood, microparticle-bound SAP and IgM were associated with complement activation. At the end of CPB, increased C3b/c (but not C4b/c) was present in systemic T2 blood compared with T1, while concentrations of microparticles binding complement components and of those binding complement activator molecules were similar. Concentrations of fluid-phase complement activation products and microparticles were similar in patients whether or not retransfused with pericardial blood. In pericardial blood of patients undergoing cardiac surgery with CPB, microparticles contribute to activation of the complement system via bound SAP and IgM. Retransfusion of pericardial blood, however, does not contribute to systemic complement activation.

    Neonatal sepsis is the most frequent health care-associated infection in neonatal units. This study aimed to analyze articles on the clinical usefulness of catheter-drawn blood samples and catheter tip cultures for the diagnosis of intravascular catheter-related bloodstream infection (CRBSI) in neonates. A systematic search was performed for studies published from 1987-2017, without language restriction. Observational studies carried out in neonates with CRBSI diagnosed using catheter-drawn blood samples or catheter tip cultures were included. A total of 412 articles were identified in the databases and 10 articles were included. The 7 studies that evaluated central venous catheter tip cultures and cultures of catheter fragments presented sensitivities ranging from 58.5%-100% and specificities ranging from 60%-95.7%. Three studies that evaluated catheter-drawn blood cultures, paired with peripheral blood cultures, reported sensitivity and specificity of 94% and 71% when evaluated for the differential time to positivity. When quantitative evaluation was performed, the sensitivity and specificity were 80% and 99.4%. Most of the studies analyzed cultures from the central venous catheter tip and catheter fragments for the diagnosis of CRBSI in neonatal populations. The results of this review suggest that the analysis of the catheter-drawn blood samples and catheter tip cultures, paired with peripheral blood cultures, are efficient methods for the diagnosis of CRBSI in neonates.

    2018-03-01

    Full Text Available Background: Pericardial disorders are a common cause of heart disease, and the most common cause of pericarditis in developing countries is tuberculous (TB pericarditis. It has been shown that prednisolone added to standard anti-TB therapy leads to a lower rate of constrictive pericarditis. We conducted a pilot study to evaluate the effect of adjunctive prednisolone treatment on the concentration of inflammatory markers in pericardial tuberculosis, in order to inform immunological mechanisms at the disease site. Methods: Pericardial fluid, plasma and saliva samples were collected from fourteen patients with pericardial tuberculosis, at multiple time points. Inflammatory markers were measured using multiplex luminex analysis and ELISA. Results: In samples from 14 patients we confirmed a strongly compartmentalized immune response at the disease site and found that prednisolone significantly reduced IL-6 concentrations in plasma by 8 hours of treatment, IL-1beta concentrations in saliva, as well as IL-8 concentrations in both pericardial fluid and saliva by 24 hours. Conclusion: Monitoring the early effect of adjunctive immunotherapy in plasma or saliva is a possibility in pericarditis. Keywords: Tuberculosis, HIV, Pericarditis, Steroids, Treatment monitoring

    Full Text Available Primary mesothelioma of the pericardium is a rare tumor and carries a dismal prognosis. This case report presents a 38-year-old man who suffered from recurrent pericardial fluid. Initial symptoms were unspecific, with dry cough and progressing fatigue. Pericardiocentesis was performed, but analyses for malignant cells and tuberculosis were negative. After recurrence a pericardiectomy was planned. At operation, partial resection of tumor tissue surrounding the heart was performed. Histopathologic examination including immunohistochemical staining for calretinin showed a biphasic mesothelioma. During the postoperative period the patient’s condition ameliorated, but symptoms recurred and the patient died 3 months after diagnosis and 15 months after the first symptoms. At autopsy, the pericardium was transformed by the tumor that also expanded into the mediastinum and had set metastases to the liver. A review of 29 cases presented in the recent literature indicates a higher incidence of malignant pericardial mesothelioma among men than women. Median age was 46 (range, 19–76 years. In pleural mesotheliomas, exposure to asbestos is a known risk factor. However, in primary pericardial mesotheliomas the evidence for asbestos as an etiologic factor seems to be less convincing (3 exposed among 14 cases. Symptoms are often unspecific and cytologic examination of pericardial fluid is seldom conclusive (malignant cells demonstrated in 4/17 cases. Partial resection of the tumor can give a period of symptom reduction. Only a few patients have been treated with chemotherapy. Median survival of patients with pericardial mesotheliomas is approximately 6 months.

    Full Text Available Optic disc pit is a congenital anomaly of the optic nerve frequently associated with macula detachment. It has a poor visual prognosis if left untreated. The treatment of the optic disc remains controversial and includes the use of laser along the edge of the optic nerve, vitrectomy with gas tamponade with or without removal of posterior hyaloid. We report a case of a 19-year-old female with a longstanding macula detachment due to optic disc pit who was treated with vitrectomy with removal of posterior hyaloid, gas tamponade, and laser. Despite longstanding macular detachment the final visual acuity was 20/25.

  8. Questionable validity of the catheter-associated urinary tract infection metric used for value-based purchasing.

    Catheter-associated urinary tract infections (CAUTIs) occur in 290,000 US hospital patients annually, with an estimated cost of $290 million. Two different measurement systems are being used to track the US health care system's performance in lowering the rate of CAUTIs. Since 2010, the Agency for Healthcare Research and Quality (AHRQ) metric has shown a 28.2% decrease in CAUTI, whereas the Centers for Disease Control and Prevention metric has shown a 3%-6% increase in CAUTI since 2009. Differences in data acquisition and the definition of the denominator may explain this discrepancy. The AHRQ metric analyzes chart-audited data and reflects both catheter use and care. The Centers for Disease Control and Prevention metric analyzes self-reported data and primarily reflects catheter care. Because analysis of the AHRQ metric showed a progressive change in performance over time and the scientific literature supports the importance of catheter use in the prevention of CAUTI, it is suggested that risk-adjusted catheter-use data be incorporated into metrics that are used for determining facility performance and for value-based purchasing initiatives.

    The purpose of this study was to identify factors associated with healthcare-acquired catheter-associated urinary tract infections (HA-CAUTIs) using multiple data sources and data mining techniques. Three data sets were integrated for analysis: electronic health record data from a university hospital in the Midwestern United States was combined with staffing and environmental data from the hospital's National Database of Nursing Quality Indicators and a list of patients with HA-CAUTIs. Three data mining techniques were used for identification of factors associated with HA-CAUTI: decision trees, logistic regression, and support vector machines. Fewer total nursing hours per patient-day, lower percentage of direct care RNs with specialty nursing certification, higher percentage of direct care RNs with associate's degree in nursing, and higher percentage of direct care RNs with BSN, MSN, or doctoral degree are associated with HA-CAUTI occurrence. The results also support the association of the following factors with HA-CAUTI identified by previous studies: female gender; older age (>50 years); longer length of stay; severe underlying disease; glucose lab results (>200 mg/dL); longer use of the catheter; and RN staffing. Additional findings from this study demonstrated that the presence of more nurses with specialty nursing certifications can reduce HA-CAUTI occurrence. While there may be valid reasons for leaving in a urinary catheter, findings show that having a catheter in for more than 48 hours contributes to HA-CAUTI occurrence. Finally, the findings suggest that more nursing hours per patient-day are related to better patient outcomes.

    Patient: Male, 38 Final Diagnosis: Constrictive pericarditis Symptoms: Shortness of breath Medication: — Clinical Procedure: Pericardiocentesis • pericardiectomy Specialty: Cardiology Objective: Unusual clinical course Background: Melioidosis is a rare tropical bacterial infection caused by the Gram-negative soil saprophyte, Burkholderia pseudomallei. Melioidosis can mimic a variety of diseases due to its varied presentation, and unless it is treated rapidly, it can be fatal. A rare case of melioidosis, with pericarditis and pericardial effusion, is described, which demonstrates the value of early diagnosis with echocardiography and pericardiocentesis. Case Report: A 38-year-old native (Iban) East Malaysian man presented with shortness of breath and tachycardia. Transthoracic echocardiography (TTE) showed cardiac tamponade. Urgent pericardiocentesis drained a large amount of purulent pericardial fluid that grew Burkholderia pseudomallei. Despite appropriate dose and duration of intravenous treatment with ceftazidime followed by meropenem, the patient developed recurrent pericardial effusion and right heart failure due to constrictive pericarditis. The diagnosis of constrictive pericarditis was confirmed by computed tomography (CT) and surgical exploration. Following pericardiectomy, his symptoms resolved, but patient follow-up was recommended for possible sequelae of constrictive pericarditis. Conclusions: After the onset of melioidosis pericarditis, the authors recommend follow-up and surveillance for possible complication of constrictive pericarditis. PMID:29551765

    Hemangiomas are rarely found in the heart and pericardial involvement is even more rare. We report a case of primary pericardial hemangioma, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Our case also highlights the importance of systematic cropping of the 3D datasets in making a diagnosis of pericardial hemangioma with a greater degree of certainty. In addition, we also provide a literature review of the features of cardiac/pericardial hemangiomas in a tabular form. © 2017, Wiley Periodicals, Inc.

  12. Intraperitoneal Urinary Bladder Perforation with Pneumoperitoneum in Association with Indwelling Foley Catheter Diagnosed in Emergency Department.

    2017-11-01

    Indwelling Foley catheter is a rare cause of urinary bladder perforation, a serious injury with high mortality that demands accurate and prompt diagnosis. While the gold standard for diagnosis of bladder injury is computed tomography (CT) cystography, few bladder ruptures associated with Foley catheter have been reported to be diagnosed in the emergency department (ED). An 83-year-old man with indwelling Foley catheter presented to the ED for hematuria and altered mental status. He was diagnosed to have intraperitoneal rupture of the urinary bladder in the ED using abdominal and pelvic CT without contrast, which demonstrated bladder wall discontinuity, intraperitoneal free fluid, and pneumoperitoneum. The patient was treated successfully with medical management and bladder drainage. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: To our knowledge, this is the first report of intraperitoneal urinary bladder perforation associated with Foley catheter diagnosed in the ED by CT without contrast. Pneumoperitoneum found in this case was a clue to the diagnosis and is a benign finding that does not necessitate urgent surgical intervention. The early and accurate diagnosis in this case allowed for effective management with good clinical outcome. The use of indwelling Foley catheter has a high prevalence, especially in long-term care facility residents, who are frequent visitors in the ED. Therefore, emergency physicians and radiologists should be familiar with the presentation and imaging findings of this potential injury associated with Foley catheters. Copyright © 2017 Elsevier Inc.

    2015-07-15

    The Focused Assessment with Sonography for Trauma examination is an invaluable tool in the initial assessment of any injured patient. Although highly sensitive and accurate for identifying hemoperitoneum, occasional false negative results do occur in select scenarios. We present a previously unreported case of survival following blunt cardiac rupture with associated negative pericardial window due to a concurrent pericardial wall laceration. A healthy 46-year-old white woman presented to our level 1 trauma center with hemodynamic instability following a motor vehicle collision. Although her abdominal Focused Assessment with Sonography for Trauma windows were positive for fluid, her pericardial window was negative. After immediate transfer to the operating room in the setting of persistent instability, a subsequent thoracotomy identified a blunt cardiac rupture that was draining into the ipsilateral pleural space via an adjacent tear in the pericardium. The cardiac injury was controlled with digital pressure, resuscitation completed, and then repaired using standard cardiorrhaphy techniques. Following repair of her injuries (left ventricle, left atrial appendage, and liver), her postoperative course was uneventful. Evaluation of the pericardial space using Focused Assessment with Sonography for Trauma is an important component in the initial assessment of the severely injured patient. Even in cases of blunt mechanisms however, clinicians must be wary of occasional false negative pericardial ultrasound evaluations secondary to a concomitant pericardial laceration and subsequent decompression of hemorrhage from the cardiac rupture into the ipsilateral pleural space.

    It has been argued that silicone ferrofluid internal tamponade (SFIT) can provide (360 deg.) tamponade of the retina in retinal detachment surgery. Provided that the produced SFIT is biocompatible, exact knowledge is needed of its elastic stability in the magnetic field produced by the semi-solid magnetic silicon band (MSB) used as a scleral buckle. We propose a quantitative, phenomenological model to estimate the critical magnetic field produced by the MSB that 'closes' retinal tears and results in the reattachment of the retina. The magnetic 'deformation' of SFIT is modeled in accordance with the deformation of a ferrofluid droplet in an external magnetic field.

    To assess the impact on the incidence of PPIVC by implementing a catheter management protocol and to determine risk factors for PPIVC development in hospitalized patients. A total of 3978 episodes of venous catheterization were prospectively included from September 2002 to December 2007. A catheter management protocol was implemented during this period of time. The incidence and variables associated to the occurrence of PPIVC were determined. The incidence of PPIVC from 2002 to 2007 was 4.8%, 4.3%, 3.6%, 2.5%, 1.3% and 1.8% (phistory of phlebitis was the only factor independently associated to phlebitis due to peripherally inserted central venous catheters (AOR 3.24; CI at 95% CI= 1.05-9.98, p=0.04). A catheter management protocol decreases the incidence of PPIVC in hospitalized patients. The risk of PPIVC increases for peripherally inserted central venous catheters when the patients have a history of phlebitis and for peripheral venous catheters when amiodarone or cefotaxime are infused. Catheterization of peripheral veins performed during morning shifts is associated with a lower incidence of PPIVC when compared with night shift catheterizations.

    Hypothyroidism is an endocrine disease with various clinical manifestations. It is a rare cause for rhabdomyolysis and massive pericardial effusion. We describe a case of severe hypothyroidism secondary to autoimmune hashimoto thyroiditis with massive pericardial effusion and rhabdomyolysis. Improvement of mentioned complications after hypothyroidism treatment and rule out of other possible causes are supportive clues that hypothyroidism is the main cause of patient's rare presentation. With the best of our knowledge, it is the first report of rhabdomyolysis and massive pericardial effusion coincidence in a patient of adult population with primary uncontrolled hypothyroidism for years.

    2018-03-01

    The aim of the study was to investigate the effect of educating nurses on preventing catheter-associated urinary tract infections in patients who undergo hip fracture surgery. Urinary tract infections after hip fracture surgery are observed at a rate of 12% to 61%, and the most important risk factor associated with urinary tract infection is considered to be the presence of urinary catheters. Nurse education about the use and management of urinary catheters is important to decrease the risk of urinary tract infections. The study was semi-experimental. The study was conducted in an orthopedics and traumatology clinic of a training hospital between January 2014-December 2015. After a power analysis was performed, a total of 60 patients fulfilled the criteria to be included in the study, with n = 30 in the pre-education group and n = 30 in the posteducation group. Nurses who worked in the orthopedics and traumatology clinic of the military hospital were the target population, and 18 nurses who consented to join the study constituted the sample. The "Patient Monitoring Form," "Nurse Information Form" and "Daily Urinary Catheter Assessment Tool" were used as data collection tools. The mean pre-education knowledge score of the nurses was found to be 68.05 ± 10.69, while the mean posteducation score was 95.13 ± 6.27. The mean catheter duration decreased from 11.06 ± 6.34 days-3.83 ± 0.95 days after the education. The catheter-associated urinary tract infection rate decreased by 9.37 per thousand. Educating nurses on preventing catheter-associated urinary tract infections in patients who underwent hip fracture surgery significantly decreased the rate of catheter-associated urinary tract infections and the duration of catheterisation. The systematic and comprehensive education of all healthcare professionals and the development and practice of catheter removal protocols could contribute to the prevention of catheter-associated urinary tract infections.

    Full Text Available Gastropericardial fistula is generally associated with benign gastric diseases and is an uncommon complication of gastric adenocarcinoma. Pericarditis and cardiac tamponade are the ultimate outcome, with extremely high mortality rates. We report a 47-year-old man with gastric adenocarcinoma who had completed radiotherapy and was on scheduled chemotherapy, who presented with fever and chest pain. Gastric adenocarcinoma complicated with gastropericardial fistula and Candida albicans pericarditis were diagnosed and treated successfully with conservative management. Initial chest radiography and computed tomography (CT revealed no evident pericardial air or fluid. However, follow-up panendoscopy 2 weeks later revealed a malignant ulcer with a fistula opening over the lesser curvature of the high body of the stomach. Subsequent chest radiography and CT revealed pneumopericardium with fluid accumulation. Emergent CT-guided pericardial drainage was performed. The fluid was positive for Candida albicans. Total parenteral nutrition and antifungal therapy were administered. The patient refused surgical intervention and survived with medical management alone. This case demonstrates that first, panendoscopy may be safely performed in patients with gastropericardial fistula without significant risk of cardiac tamponade; second, although early diagnosis of gastropericardial fistula is generally important, delayed recognition may not lead to devastating outcomes even in the absence of surgical intervention.

  3. Catheter Occlusion in Home Infusion: The Influence of Needleless Connector Design on Central Catheter Occlusion.

    Williams, Ann

    Thrombotic catheter occlusion is a common complication associated with central venous catheters (CVCs). A wide variety of needleless connectors that differ greatly in design and function are available for use with CVCs; however, there are a limited number of studies comparing the catheter occlusion rate associated with differently designed needleless connectors. This retrospective observational study compared occlusion rates associated with a split-septum neutral-displacement needleless connector versus those of a solid-surface neutral-reflux needleless connector in patients undergoing home infusion therapy.

    The aim of this study was to assess short and middle term outcome of radiofrequency catheter ablation for drug-refractory paroxysmal and sustained atrial fibrillation. Subjects were 30 patients of atrial fibrillation (19 paroxysmal, 11 sustained) who underwent extensive pulmonary vein isolation from January 2007 to August 2009 in our department. Twenty three men and seven women, aged from 44 to 76 years, were enrolled. Follow-up period was one to 32 months. Drug free success was 33%, but symptoms and electrocardiogram (EGG) findings were improved in 93 % of the patients by administration of anti-arrhythmic agents. Five of the six patients with bradycardia-tachycardia syndrome was free from pacemaker implantation. Left ventricular ejection fraction was improved in two patients with dilated cardiomyopathy (DCM)-like left ventricular dysfunction. One case had cardiac tamponade and transient ST elevation due to right coronary air embolism were observed in two cases. There were no death and no cerebrovascular events during the procedures and follow-up periods. In conclusion, radiofrequency catheter ablation for paroxysmal and sustained atrial fibrillation in our department may be highly acceptable new method for improving the symptoms and clinical signs of the patients.

    PURPOSE:: To evaluate decafluoro-di-n-pentyl ether (DFPE) as a vitreous tamponade by examining ocular tolerance in rabbits\\' eyes. METHODS:: Thirteen rabbits were divided into 4 groups after mechanical vitrectomy and were followed up to 12 months. The tamponade remained in the eye for 6 months in Group 1 (DFPE) and Group 3 (DFPE and silicone oil) and for 12 months in Group 2 (DFPE). Group 4 served as control. RESULTS:: In Groups 1, 2, and 3, dispersion of the fluid appeared 2 weeks postoperatively. Posterior subcapsular cataracts appeared in rabbits\\' eyes with large fills of DFPE (>50%). Histologic findings in Groups 1 and 2 showed no detectable change in outer nuclear layer thickness. Except for some vacuolations, the inner retina was well preserved in all injected rabbits\\' eyes. On the electroretinography of injected rabbits\\' eyes, there was no effect on the a wave amplitude and b wave implicit time, but the b wave amplitude was elevated with statistical significance (P < 0.001) at 1, 3, and 6 months postoperatively but with no statistical significance (P > 0.05) after that period when compared with Group 4 and unoperated fellow rabbits\\' eyes of each group. CONCLUSION:: Decafluoro-di-n-pentyl ether demonstrated minimum adverse effects in retinal rabbits; further studies are needed before clinical use as short-term tamponade.

    Full Text Available We present the case of a 49-year-old woman, with previous clinical antecedents of recent hepatic metastasis, who was admitted to the ICU due to respiratory failure and hemodynamic instability. She was found to have purulent pericarditis complicated by pericardial tamponade and pleural effusion, as well as surgical site infection, which was the origin of the disease. Cultures of the surgical wound and the pericardial effusion were positive for Enterococcus faecalis and Escherichia coli. A pericardial tap was performed and the intra-abdominal abscess was surgically drained. Pleural effusion was also evacuated. She received antibiotic treatment and recovered successfully. The only after-effect was a well-tolerated effusive-constrictive pericarditis.

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    To compare the efficacy and safety of 20% sulfur hexafluoride gas (SF6) and air tamponade in patients who underwent noniridectomized Descemet membrane endothelial keratoplasty (DMEK). A retrospective chart review of patients who underwent DMEK with either air or SF6 tamponade: 41 eyes received air tamponade (group 1) and 41 received SF6 tamponade (group 2). Best spectacle-corrected visual acuity, endothelial cell density, and complications including graft detachment and elevated intraocular pressure were compared. The mean follow-up time was 8 ± 4 months in group 1 and 3 ± 2 months in group 2. Mean best spectacle-corrected visual acuity improved from 1.12 ± 0.88 to 0.64 ± 0.78 logarithm of the minimum angle of resolution (logMAR) in group 1 (P = 0.009) and from 1.00 ± 0.78 to 0.62 ± 0.53 logMAR in group 2 (P = 0.006). The graft detachment rate was 39% (16 eyes) in group 1 and 42% (17 eyes) in group 2 (P = 0.822). The rate of graft detachment larger than one third of the graft area was 17% in group 1 and 20% in group 2 (P = 0.775). Rebubbling was performed in 26.8% and 20% of eyes in group 1 and 2, respectively (P = 0.43). Average endothelial cell loss was 32% in group 1 and 33% in group 2 (P = 0.83). In the immediate postoperative period, elevated intraocular pressure was observed in 2 eyes (5%) in group 1 and in 4 eyes (10%) in group 2 (P = 0.4). There was 1 primary graft failure in each group. Use of air with it being readily available and short acting is a good method of Descemet membrane tamponade in noniridectomized DMEK.

    Objective: To know the sensitivity of polymerase chain reaction (PCR) in pericardial fluid and response to antituberculous treatment (ATT) in PCR positive patients who were presumptively diagnosed and treated as tuberculous pericardial effusion. Methodology: This was a descriptive cross sectional study carried out from June 1, 2009 to 31 May 2010 at Cardiology Department, Lady Reading Hospital, Peshawar. Patients with presumptive diagnosis and receiving treatment for tuberculous pericardial effusion were included. Pericardial fluid sample was aspirated under fluoroscopy for the routine work up. The specimens were subjected to PCR detection of mycobacterium tuberculous DNA. Results: During 12 month study period, a total of 54 patients with large pericardial effusion presented to Cardiology department, Lady Reading Hospital, Peshawar. Of them, 46 patients fulfilled the criteria for presumptive diagnosis of tuberculous pericardial effusion. PCR for mycobacterium tuberculous DNA in pericardial fluid was positive in 45.7%(21). Patients were followed for three months. In PCR positive group, 01 patient while in PCR negative group 3 patients were lost to follow up. Among PCR positive patients 17(85%) while in PCR negative group 11(47.82%) patient responded to ATT both clinically and echo-cardio graphically. We found that patients who were PCR positive responded better to therapy than those who were PCR negative and this finding was statistically significant (p=0.035). Conclusion: PCR, with all its limitations, is potentially a useful diagnostic test in patients with presumptively diagnosed tuberculous pericardial effusion. A PCR positive patient responds better to therapy as compared to PCR negative patient. (author)

    2015-03-01

    Full Text Available Background: There are some reports in the literature, which suggest that cardiac tamponade drainage may transiently affect systolic function and also cause acute respiratory distress syndrome (ARDS. We did not find any reports of acute ventricular failure and ARDS secondary to mediastinal tumor resection without tamponade. Case Report: Here we report a 48-year-old woman presenting with massive pericardial effusion without tamponade in whom tumor was resected through median sternotomy using cardiopulmonary bypass. ARDS and acute heart failure were two rare complications that happened at the end of the operation secondary to a sudden decompression of the heart from tumor pressure. Conclusion: ARDS and acute heart failure are two rare complications, which can happen after large mediastinal tumor resection.

    We present the case of a 37-year-old nulliparous woman in whom acute massive uterine bleeding during dienogest therapy was successfully treated using intrauterine balloon tamponade. Abnormal uterine bleeding and several cases of profuse bleeding causing severe anemia in association with dienogest therapy have been reported, but this is the first reported case involving hypovolemic shock. While successful control of postpartum hemorrhage with intrauterine balloon tamponade has been well described, applications for non-obstetric bleeding, particularly in the presence of underlying diseases, such as adenomyosis, have only rarely been reported. This procedure can be easily, promptly, and safely implemented without analgesia, anesthesia, or laparotomy; it can be used with a minimally dilated external cervical os or narrow uterine cavity; and it can preserve fertility. © 2012 The Authors.

    to investigate the incidence of phlebitis and its association with risk factors when using peripheral IV catheters (PIC) and following their removal - (post-infusion phlebitis) in hospitalized adults. a cohort study of 171 patients using PIC, totaling 361 punctures. Sociodemographic variables and variables associated with the catheter were collected. Descriptive and analytical statistical analyses were performed. average patient age was 56.96 and 51.5% of the sample population was male. The incidence of phlebitis was 1.25% while using PIC, and 1.38% post-infusion. The incidence of phlebitis while using PIC was associated with the length of time the catheter remained in place, whereas post-infusion phlebitis was associated with puncture in the forearm. Ceftriaxone, Clarithromycin and Oxacillin are associated with post-infusion phlebitis. this study made it possible to investigate the association between risk factors and phlebitis during catheter use and following its removal. The frequency of post-infusion phlebitis was larger than the incidence of phlebitis with the catheter in place, with Phlebitis Grade III and II being the most frequently found in each of these situations, respectively. Aspects related to post-infusion phlebitis can be explained, given the limited number of studies addressing this theme from this perspective. investigar a incidência de flebites e a associação de fatores de risco com a sua ocorrência durante o uso e após a retirada do cateter intravenoso periférico - CIP (Flebite pós-infusão) em adultos hospitalizados. estudo de coorte com 171 pacientes com CIP, totalizando 361 punções.

    Full Text Available Coronary artery perforation is an uncommon complication in patients with coronary heart disease undergoing percutaneous coronary intervention. However, pericardial tamponade following coronary artery perforation may be lethal, and prompt treatment is crucial in managing such patients. Balloon occlusion and the reversal of anticoagulant activity are the common methods used to prevent cardiac tamponade by reducing the amount of bleeding. Herein, we discuss the pros and cons of currently used occlusion types for coronary perforation. Optimal balloon occlusion methods should reduce the amount of bleeding and ameliorate subsequent myocardial ischemia injury, even during cardiac surgery.

    Angiocardiography is still considered the gold standard in the estimation of functional parameters of the heart. However because of the inferior density resolution and the draw back of superimposition of cardiac structures angiocardiography provides only limited information about non cardiac and some cardiac structures for instance: The perimyo-, endocardium, the valves, the myocardial perfusion and metabolism or coronary blood flow. The present diagnostic and prognostic validity of CT and MR in visualizing the pericardium, the left ventricular myocardium, the heart chambers and the great heart vessels in the clinical work up of patients with pericardial and congestive heart failure is demonstrated. MR is more reliable in the diagnosis of left ventricular myocardial atrophy or fibrosis than CT. Disadvantages of MR include the failure to identify endo-, myo-and pericardial calcifications. The measurable improvement in the visualization of systolic and diastolic myocardial wall thickness using MR is of marked prognostic value in the preoperative exclusion of myocardial atrophy or fibrosis in patients with pericardial constriction

    1998-01-01

    From March 1982 to December 1995, 2,607 Fisics-Incor bovine pericardial bioprostheses were implanted in 2,259 patients. Mean age was 47.2 +/- 17.5 years, and 55% were male. Rheumatic fever was present in 1,301 (45.7%) patients. One thousand and seventy-three aortic valve replacements, 1,085 mitral replacements, 27 tricuspid replacements, 195 mitral-aortic replacements, and 16 other combined valve replacements were carried out. Combined procedures were performed in 788 (32.9%) patients, the most frequent being tricuspid valve repair (9.2%) and coronary artery bypass grafting (7.7%). Hospital mortality was 8.6% (194 patients), 8.6% for the mitral group, 4.7% for the aortic group, and 12.8% for double-valve replacements. The linear rates for calcification, thromboembolism, rupture, leak and endocarditis were, respectively, 1.1%, 0.2%, 0.9%, 0.1% and 0.5% patient-year. The actuarial survival curve was 56.7 +/- 5.4% in 15 years. Survival free from endocarditis was 91.92%, survival free from thromboembolism was 95 +/- 1.7%, survival free from rupture was 43.7 +/- 9.8%, survival free from leak was 98.9 +/- 4.5%, and survival free from calcification was 48.8 +/- 7.9% in 15 years. In the late postoperative period, 1,614 (80.6%) patients were in New York Heart Association functional Class I. We conclude that the results with the Fisics-Incor bovine pericardial prostheses were satisfactory in our group of patients.

    Existing knowledge of emergency department (ED) catheter-associated urinary tract infection (CAUTI) prevention is limited. We aimed to describe the motivations, perceived risks for CAUTI acquisition, and strategies used to address CAUTI risk among EDs that had existing CAUTI prevention programs. In this qualitative comparative case study, we enrolled early-adopting EDs, that is, those using criteria for urinary catheter placement and tracking the frequency of catheters placed in the ED. At 6 diverse facilities, we conducted 52 semistructured interviews and 9 focus groups with hospital and ED participants. All ED CAUTI programs originated from a hospitalwide focus on CAUTI prevention. Staff were motivated to address CAUTI because they believed program compliance improved patient care. ED CAUTI prevention was perceived to differ from CAUTI prevention in the inpatient setting. To identify areas of ED CAUTI prevention focus, programs examined ED workflow and identified 4 CAUTI risks: (1) inappropriate reasons for urinary catheter placement; (2) physicians' limited involvement in placement decisions; (3) patterns of urinary catheter overuse; and (4) poor insertion technique. Programs redesigned workflow to address risks by (1) requiring staff to specify the medical reason for catheter at the point of order entry and placement; (2) making physicians responsible for determining catheter use; (3) using catheter alternatives to address patterns of overuse; and (4) modifying urinary catheter insertion practices to ensure proper placement. Early-adopting EDs redesigned workflow to minimize catheter use and ensure proper insertion technique. Assessment of ED workflow is necessary to identify and modify local practices that may increase CAUTI risk.

    Pericardial effusion on CT scans demonstrates very high shape and volume variability and very low contrast to adjacent structures. This inhibits traditional automated segmentation methods from achieving high accuracies. Deep neural networks have been widely used for image segmentation in CT scans. In this work, we present a two-stage method for pericardial effusion localization and segmentation. For the first step, we localize the pericardial area from the entire CT volume, providing a reliable bounding box for the more refined segmentation step. A coarse-scaled holistically-nested convolutional networks (HNN) model is trained on entire CT volume. The resulting HNN per-pixel probability maps are then threshold to produce a bounding box covering the pericardial area. For the second step, a fine-scaled HNN model is trained only on the bounding box region for effusion segmentation to reduce the background distraction. Quantitative evaluation is performed on a dataset of 25 CT scans of patient (1206 images) with pericardial effusion. The segmentation accuracy of our two-stage method, measured by Dice Similarity Coefficient (DSC), is 75.59+/-12.04%, which is significantly better than the segmentation accuracy (62.74+/-15.20%) of only using the coarse-scaled HNN model.

    To compare the safety and effectiveness of over-the-wire catheter exchange (catheter-exchange) with catheter removal and replacement (removal-replacement) at a new site for infected or malfunctioning tunneled infusion catheters. Using a quality assurance database, 61 patients with tunneled infusion catheters placed during the period July 2001 to June 2009 were included in this study. Patients receiving hemodialysis catheters were excluded. Catheter-exchange was performed in 25 patients, and same-day removal-replacement was performed in 36 patients. Data collected included demographic information, indication for initial catheter placement and replacement, dwell time for the new catheter, and ultimate fate of the new device. Statistical comparisons between the two cohorts were analyzed using the Kaplan-Meier technique and Fisher exact test. Catheters exchanged over the wire remained functional without infection for a median of 102 days (range, 2-570 days), whereas catheters removed and replaced were functional for a median 238 days (range, 1-292 days, P = .12). After catheter replacement, there were 11 instances of subsequent infection in the catheter-exchange group and 7 instances in the removal-replacement cohort, accounting for infection rates of 4.4 and 2.3 per 1,000 catheter days (P = .049). Patients in the catheter-exchange group had 3.2 greater odds of infection compared with patients in the removal-replacement group. Five malfunction events occurred in each group, accounting for 2.0 and 1.7 malfunctions per 1,000 catheter days in the catheter-exchange and removal-replacement groups (P = .73). Catheter-exchange of tunneled infusion catheters results in a higher infection rate compared with removal-replacement at a new site. The rate of catheter malfunction is not significantly different between the two groups. Catheter-exchange is an alternative for patients with tunneled infusion catheters who have limited venous access, but this technique should not be

    Central venous catheter (CVC) and hemodialysis (HD) catheter usage are associated with complications that occur during catheter insertion, dwell period, and removal. This study aims to identify and describe the incidence rates of catheter-related complications in a large patient population in a United States-based health care claims database after CVC or HD catheter placement. Patients in the i3 InVision DataMart® health care claims database with at least 1 CVC or HD catheter insertion claim were categorized into CVC or HD cohorts using diagnostic and procedural codes from the US Renal Data System, American College of Surgeons, and American Medical Association's Physician Performance Measures. Catheter-related complications were identified using published diagnostic and procedural codes. Incidence rates (IRs)/1000 catheter-days were calculated for complications including catheter-related bloodstream infections (CRBSIs), thrombosis, embolism, intracranial hemorrhage (ICH), major bleeding (MB), and mechanical catheter-related complications (MCRCs). Thirty percent of the CVC cohort and 54% of the HD cohort had catheter placements lasting <90 days. Catheter-related complications occurred most often during the first 90 days of catheter placement. IRs were highest for CRBSIs in both cohorts (4.0 [95% CI, 3.7-4.3] and 5.1 [95% CI, 4.7-5.6], respectively). Other IRs in CVC and HD cohorts, respectively, were thrombosis, 1.3 and 0.8; MCRCs, 0.6 and 0.7; embolism, 0.4 and 0.5; MB, 0.1 and 0.3; and ICH, 0.1 in both cohorts. Patients with cancer at baseline had significantly higher IRs for CRBSIs and thrombosis than non-cancer patients. CVC or HD catheter-related complications were most frequently seen in patients 16 years or younger. The risk of catheter-related complications is highest during the first 90 days of catheter placement in patients with CVCs and HD catheters and in younger patients (≤16 years of age) with HD catheters. Data provided in this study can be applied

    Full Text Available Background: PR interval prolongation has recently been shown to associate with advanced left atrial remodeling and atrial fibrillation (AF recurrence after catheter ablation. While different genome-wide association studies (GWAS have implicated 13 loci to associate with the PR interval as an AF endophenotype their subsequent associations with AF remodeling and response to catheter ablation are unknown. Here, we perform a gene-based analysis of GWAS data to test the hypothesis that PR interval candidate genes also associate with left atrial remodeling and arrhythmia recurrence following AF catheter ablation.Methods and Results: Samples from 660 patients with paroxysmal (n = 370 or persistent AF (n = 290 undergoing AF catheter ablation were genotyped for ~1,000,000 SNPs. Gene-based association was investigated using VEGAS (versatile gene-based association study. Among the 13 candidate genes, SLC8A1, MEIS1, ITGA9, SCN5A, and SOX5 associated with the PR interval. Of those, ITGA9 and SOX5 were significantly associated with left atrial low voltage areas and left atrial diameter and subsequently with AF recurrence after radiofrequency catheter ablation.Conclusion: This study suggests contributions of ITGA9 and SOX5 to AF remodeling expressed as PR interval prolongation, low voltage areas and left atrial dilatation and subsequently to response to catheter ablation. Future and larger studies are necessary to replicate and apply these findings with the aim of designing AF pathophysiology-based multi-locus risk scores.

    Chylopericardium is a rare disease and affects both sexes equally from neonate to adult. Usually, there are abnormal connections between the pericardial cavity and thoracic lymphatic systems. These connections are detected by (1) recovery of orally administered Sudan III from pericardial fluid, (2) evidence of radioactivity in the pericardial fluid by paracentesis after oral administration of 131 I-labeled triolein, and (3) lymphangiography. However, these method are technically difficult and invasive, thus sometimes dangerous for children. We employed precordial pericardial imaging after oral administration of 131 I-labeled triolein on a 9-year-old Japanese girl wth isolated chylopericardium before and after surgery. Abnormal connections and the back-ward flow to the pulmonary lymphatics were demonstrated by this method. This is an easy, non-invasive, reliable and safe method for detecting the abnormal connections of pericardial and lymphatic systems in children with chylopericardium. (author)

    Full Text Available Abstract Background The tumorous infiltration or carcinosis of the pericardium could cause pericardial effusion in up to one-third of cases of malignancy, thus potentially interfere with the otherwise desirable oncological treatment. The existing surgical methods for the management of pericardial fluid are well-established but are not without limitations in the symptomatic relief of malignant pericardial effusion (MPE. The recurrence rate ranges between 43 and 69% after pericardiocentesis and 9 to 16% after pericardial drainage. The desire to overcome relative limitations of the existing methods led us to explore an alternative approach. Methods The standard armamentarium of the Carlens collar mediastinoscopy procedure was utilized in a Chamberlain parasternal approach of the pericardial sac. The laterality of approach was decided based upon the pleural involvement, as tumor-free pericardiopleural reflection is required. A pericardio-pleural window at least 3 cm in diameter was created. From January 2000 to December 2009, 22 cases were operated on with mediastinoscope-controlled parasternal fenestration (MCPF. Considering the type of the primary tumor, there were 11 lung cancer, 6 breast cancers, 2 haematologic malignancies and in 3 patients the origin of malignancy could not be verified. Results There were no operative deaths. We lost one patient (4.5% in the postoperative hospital period. All of the surviving patients had a minimum of 2 months of symptom-free survival. We detected transient recurrence of MPE in one patient (4.5% 14 days after the MCPF, which disappeared spontaneously after 24 hours. Conclusion The MCPF offers a real alternative in certain cases of pericardial effusion. We recommend this method especially for the definitive surgical palliation of MPE.

    Peripherally inserted central catheters (PICCs) are associated with central line-associated bloodstream infection (CLABSI). The magnitude of this risk relative to central venous catheters (CVCs) is unknown. To compare risk of CLABSI between PICCs and CVCs. MEDLINE, CinAHL, Scopus, EmBASE, and Cochrane CENTRAL were searched. Full-text studies comparing the risk of CLABSI between PICCs and CVCs were included. Studies involving adults 18 years of age or older who underwent insertion of a PICC or a CVC and reported CLABSI were included in our analysis. Studies were evaluated using the Downs and Black scale for risk of bias. Random effects meta-analyses were used to generate summary estimates of CLABSI risk in patients with PICCs versus CVCs. Of 1,185 studies identified, 23 studies involving 57,250 patients met eligibility criteria. Twenty of 23 eligible studies reported the total number of CLABSI episodes in patients with PICCs and CVCs. Pooled meta-analyses of these studies revealed that PICCs were associated with a lower risk of CLABSI than were CVCs (relative risk [RR], 0.62; 95% confidence interval [CI], 0.40-0.94). Statistical heterogeneity prompted subgroup analysis, which demonstrated that CLABSI reduction was greatest in outpatients (RR [95% CI], 0.22 [0.18-0.27]) compared with hospitalized patients who received PICCs (RR [95% CI], 0.73 [0.54-0.98]). Thirteen of the included 23 studies reported CLABSI per catheter-day. Within these studies, PICC-related CLABSI occurred as frequently as CLABSI from CVCs (incidence rate ratio [95% CI], 0.91 [0.46-1.79]). Only 1 randomized trial met inclusion criteria. CLABSI definition and infection prevention strategies were variably reported. Few studies reported infections by catheter-days. Although PICCs are associated with a lower risk of CLABSI than CVCs in outpatients, hospitalized patients may be just as likely to experience CLABSI with PICCs as with CVCs. Consideration of risks and benefits before PICC use in inpatient

    Castleman disease (CD) is a rare poorly understood lymphoproliferative disorder. Pediatric onset CD has been reported before. However, most of them have benign unicentric pattern. Multicentric CD (MCD) is quite rare in children. Herein, we report a 13-year-old adolescent boy with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. MCD should be considered in the differential diagnosis of pleural and/or pericardial effusion with unexplained lymph nodes in children. What is Known •Pediatric Castleman disease (CD) most commonly occurs in the unicentric form, which typically is asymptomatic and cured by lymph node excision. •The diagnosis of MCD can be difficult owing to the heterogeneity of presentation and potential for nonspecific multisystem involvement. What is New •A 13-year-old adolescent boy was diagnosed with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. •In a pediatric patient with fever, pleural-pericardial effusion and multiple lymph nodes, MCD should be considered in differantial diagnosis.

    2018-05-14

    Many clinicians know from experience and medical epidemiological literature that the risk of central line-associated bloodstream infections (CLABSI) increases rapidly with a prolonged catheter dwell-time, but how this infection risk increases over time remains obscure. In this manuscript, a clinically useful rule of thumb is derived, stating that the risk of CLABSI increases in a quadratic fashion with the increase in catheter dwell-time. The proposed rule of thumb could be considered a quick and effortless clinical tool to rationally predict the pattern of CLABSI risk with an increasing catheter dwell-time. Copyright © 2018.

    1987-01-01

    A 14 C-radiorespirometric assay was used to show the sensitivity of fixed-film (sessile), catheter-associated and free-living (planktonic) cells of Pseudomonas aeruginosa to varying concentrations (100 micrograms/mL to 1000 micrograms/mL) tobramycin sulfate. This strain of P. aeruginosa has an MIC of 0.6 microgram/ml and an MBC of 50 micrograms/mL when tested by conventional methods. When 14 C-glutamic acid was used as a substrate in this radiorespirometric assay, it could be completed in less than one hour and planktonic samples showed a significant reduction in mineralization activity (evolution of 14 CO 2 ) within eight hours of the antibiotic challenge. These changes in respiratory activity appeared to be dose and time dependent. Within 18 hr. at 1000 micrograms/mL, there was no significant residual respiratory activity in planktonic samples. Some residual respiratory activity was detected, however, in samples exposed to 100 micrograms/mL for 36 hours. The mineralization activity of sessile catheter-associated bacteria was unaffected by four hr. and eight hr. exposures to 1000 micrograms/mL of the antibiotic. A significant reduction in respiratory activity was recorded in catheter samples exposed for 18 hr. or more at each concentration examined. Unlike the planktonic samples, however, the antibiotic challenge failed to eradicate the metabolic activity of the attached bacteria. Antibiotic stressed, catheter-associated bacteria transferred to a post-exposure enrichment broth showed a limited ability to re-establish respiratory activity. This apparent recovery was limited to antibiotic exposures less than 24 hr. and was not observed in planktonic samples. The radioisotopic assay is a non-culture method which can be used to assess the antibiotic sensitivity of both planktonic bacteria and in situ biofilm populations

  19. Intracorporeal knotting of a femoral nerve catheter

    2015-01-01

    Full Text Available Peripheral nerve catheters are effective and well-established tools to provide postoperative analgesia to patients undergoing orthopedic surgery. The performance of these techniques is usually considered safe. However, placement of nerve catheters may be associated with a considerable number of side effects and major complications have repeatedly been published. In this work, we report on a patient who underwent total knee replacement with spinal anesthesia and preoperative insertion of femoral and sciatic nerve catheters for postoperative analgesia. During insertion of the femoral catheter, significant resistance was encountered upon retracting the catheter. This occurred due to knotting of the catheter. The catheter had to be removed by operative intervention which has to be considered a major complication. The postoperative course was uneventful. The principles for removal of entrapped peripheral catheters are not well established, may differ from those for neuroaxial catheters, and range from cautious manipulation up to surgical intervention.

    To prevent peritoneal dialysis (PD)-related infection, components of self-catheter care have been emphasized. However, studies on the effectiveness of home recording for the prevention of PD-related infections are limited. This study aimed to examine the association between keeping home records of catheter exit site and incidence of PD-related infections. Home record books were submitted by patients undergoing PD. The proportion of days on which exit-site home recording was carried out for 120 days (0-100%) was obtained. The patients were divided into the frequent home recording group (≥ 40.5%; median value) and the infrequent home recording group (home recording groups for PD-related infection were 1.58 (95% confidence interval [CI], 0.72-3.46) in the univariate analysis and 1.49 (95% CI, 0.65-3.42) in the multivariate analysis. The IRRs of the frequent versus infrequent home recording groups for composite of surgery to create a new exit site and removal of PD catheter were 0.55 (95% CI, 0.78-3.88) and 0.35 (95% CI, 0.06-1.99), respectively. This study could not prove that keeping home records of patients' catheter exit site is associated with a lower incidence of PD-related infections.

    gland. At the time of diagnosis, patients present lymph node and lung metastasis. It affects mainly young women. This case report describes a cardiac tamponade as the initial manifestation of an unusual variant of papillary thyroid carcinoma. A 32 year-old woman was attended at the emergency room with epigastric pain and dry cough. Physical examination revealed hypotension, tachycardia and decreased heart sounds. An echocardiogram confirmed severe pericardial effusion. Pericardial fluid cytology was positive for malignancy. The patient evolved with recurrent pericardial effusion and a pleuropericardial window was performed. At this procedure, a subpleural nodular lesion was found, which histology corresponded to metastases of papillary carcinoma, probably from thyroid origin. Total thyroidectomy was performed. The final diagnosis was papillary carcinoma, diffuse sclerosing variant. This variant infiltrates the connective tissue of the interfollicular spaces, mimicking thyroiditis and it is associated with early vascular permeation. This tumor, compared to the classic variants of thyroid carcinoma, is more aggressive and it has higher risk of recurrence. Papillary thyroid carcinoma should be considered as differential diagnosis in our population, in all metastatic papillary lesions, and even more in young female patients.

The current article describes rare patients with effusion who after pericadiectomy and transient hemodynamic improvement rapidly developed progressive heart failure and subsequent multi organ failure.Methods: During periods of five years, 423 patients in our hospital underwent pericardiotomy for decompression of effusion. The clinical characteristics of those patient with postoperative low cardiac output (B group (14 cases recorded and compared with other patients without this postoperative complication (A group by test and X2. Significant variables in invariables (P≤0.1 entered in logistic regression analysis and odd ratio of these significant variables obtained. Results: Idiopathic pericardial effusion, malignancy, renal failure, connective tissue disease, viral pericarditis was found in 125 patients (27%, 105 patients (25.4%, 65 patients (15.6%, 50 (17.1% and 10 (2.4% of patients subsequently. The factors that predict post-operative death in logistic regression analysis were malignancy, radiotherapy, constrictive pericarditis inotropic drug using IABP using, pre-operative EF and pericardial calcification.Conclusion: Certain preoperative variables such as malignancy, radiotherapy, low EF, calcified pericardium and connective tissue disease are associated with POLCOS and post-operative risk of death. This paradoxical response to pericardial decompression may be more frequent than currently appreciated. Its cause may relate to the sudden removal of the chronic external ventricular support from the effusion or thicken pericardium resulting in ventricular dilatation and failure or intra operative myocardial injury due to pericardiectomy of calcified pericardium, radiation and cardiomyopathy.

    For modern medicine central venous catheters play an important role for diagnostic and therapeutic options. Catheter implantation, complication detection and therapy of catheter complications are an increasing demand for the radiologist. The review article provides an overview of different catheter types, their indications, advantages and disadvantages. Catheter malpositions are usually detectable in conventional X-ray. Most malpositions are correctable using interventional-radiological techniques. In addition therapeutical options for thrombotic complications (venous thrombosis, catheter occlusion, fibrin sheath) are discussed. In case of an infectious catheter complication, usually a catheter extraction and re-implantation is necessary

    Peritoneal dialysis (PD) catheter occlusion is a common complication with up to 36% of catheter obstructions described in the literature. We present a comparison of complications and outcome after implantation of PD catheters in a transplant surgical and a pediatric surgical department. We retrospectively analyzed 154 PD catheters, which were implanted during 2009-2015 by transplant surgeons (TS, University Medical Center Hamburg-Eppendorf, Germany, n=85 catheters) and pediatric surgeons (PS, Charité University Medicine Berlin, Germany, n=69 catheters) in 122 children (median (range) age 3.0 (0.01-17.1) years) for acute (n=65) or chronic (n=89) renal failure. All catheters were one-cuffed or double-cuffed curled catheters, except that straight catheters were implanted into smaller children (n=19) by TS in Hamburg. Patient characteristics and operation technique did not differ between the departments. Peritonitis was the most common complication (33 catheters, 21.4%). Leakage (n=18 catheters, 11.7%) occurred more often in children weighing <10kg (p<0.001). The incidence of obstruction and dysfunction was significantly higher in catheters used in PS than catheters used in TS (30.4% vs. 11.8%, p=0.004). Omentectomy did not reduce the incidence of catheter obstruction (p=1.0). Perforation at the catheter tips was larger and appeared to be rougher in catheters used in PS than the catheters in TS. The type of catheter and presumably the type of perforation at the catheter tip may influence the incidence of peritoneal dialysis catheter obstruction. Copyright © 2017 Elsevier Inc.

    To compare the clinical outcomes following Descemet's membrane endothelial keratoplasty (DMEK) with 100% air tamponade versus 10% sulfur hexafluoride (SF 6 ) tamponade. Retrospective analysis of 108 consecutive DMEK cases subdivided by anterior chamber tamponade with 54 eyes receiving 10% SF 6 and 54 eyes receiving 100% air injection. A post-hoc matched analysis revealed no statistically significant differences between the groups. The main outcome measurements were the complication rate, including intra- and postoperative complications and graft detachment rate requiring re-bubbling. Clinical outcome included best-corrected visual acuity (BCVA), endothelial cell count (ECC), and central corneal thickness (CCT) measured 1, 3, and 6 months after DMEK surgery. The graft detachment rate with consecutive re-bubbling was 18.5% in the air group and 22.2% in the SF 6 group (p = 0.2). Remaining small peripheral graft detachments with a clear cornea occurred more often in the 100% air group (air: 22.2%; 12/54, 6/12 inferior compared to SF 6 : 7.4%; 4/54, 2/4 inferior; p = 0.06). The primary graft failure rate was comparable between the two groups. No complete graft detachment occurred. Outcome results for BCVA, ECC, and CCT at all follow-up time points were comparable between the two groups. The clinical outcomes (including re-bubbling rate, primary graft failure rate, and endothelial cell loss) were comparable with 100% air versus 10% SF 6 tamponade, whereas other studies suggest that a higher SF 6 concentration (20%) may result in a lower re-bubbling rate.

    The prevalence of prosthesis-patient mismatch (PPM) and its impact on survival after aortic valve replacement have not been clearly defined. Historically, the presence of PPM was identified from postoperative echocardiograms or preoperative manufacturer-provided charts, resulting in wide discrepancies. The 2009 American Society of Echocardiography (ASE) guidelines proposed an algorithmic approach to calculate PPM. This study compared PPM prevalence and its impact on survival using 3 modalities: (1) the ASE guidelines-suggested algorithm (ASE PPM); (2) the manufacturer-provided charts (M PPM); and (3) the echocardiographically measured, body surface area-indexed, effective orifice area (EOAi PPM) measurement. A total of 614 patients underwent aortic valve replacement with bovine pericardial valves from 2004 to 2009 and had normal preoperative systolic function. EOAi PPM was severe if EOAi was ≤ 0.60 cm(2)/m(2), moderate if EOAi was 0.60 to 0.85 cm(2)/m(2), and absent (none) if EOAi was ≥ 0.85 cm(2)/m(2). ASE PPM was severe in 22 (3.6%), moderate in 6 (1%), and absent (none) in 586 (95.4%). ASE PPM was similar to manufacturer-provided PPM (P=1.00). ASE PPM differed significantly from EOAi PPM (P<0.001), which identified severe mismatch in 170 (29.7%), moderate in 191 (33.4%), and absent (none) in 211 patients (36.9%). Irrespective of the PPM classification method, PPM did not adversely affect midterm survival (average follow-up, 4.1 ± 1.8 years; median, 3.9 years; range, 0.01-8 years). There were no reoperations for PPM. In patients with normal systolic function undergoing bovine pericardial aortic valve replacement, the prevalence of PPM using the algorithmic-ASE approach was low and correlated well with manufacturer-provided PPM. Independent of the method of PPM assessment, PPM was not associated with medium-term mortality.

    The development and in vivo testing of a high-intensity ultrasound thermal ablation catheter for epicardial ablation of the left ventricle (LV) is presented. Scar tissue can occur in the mid-myocardial and epicardial space in patients with nonischemic cardiomyopathy and lead to ventricular tachycardia. Current ablation technology uses radiofrequency energy, which is limited epicardially by the presence of coronary vessels, phrenic nerves, and fat. Ultrasound energy can be precisely directed to deliver targeted deep epicardial ablation while sparing intervening epicardial nerve and vessels. The proof-of-concept ultrasound applicators were designed for sub-xyphoid access to the pericardial space through a steerable 14-Fr sheath. The catheter consists of two rectangular planar transducers, for therapy (6.4 MHz) and imaging (5 MHz), mounted at the tip of a 3.5-mm flexible nylon catheter coupled and encapsulated within a custom-shaped balloon for cooling. Thermal lesions were created in the LV in a swine (n = 10) model in vivo. The ultrasound applicator was positioned fluoroscopically. Its orientation and contact with the LV were verified using A-mode imaging and a radio-opaque marker. Ablations employed 60-s exposures at 15 - 30 W (electrical power). Histology indicated thermal coagulation and ablative lesions penetrating 8 - 12 mm into the left ventricle on lateral and anterior walls and along the left anterior descending artery. The transducer design enabled successful sparing from the epicardial surface to 2 - 4 mm of intervening ventricle tissue and epicardial fat. The feasibility of targeted epicardial ablation with catheter-based ultrasound was demonstrated.

    Proteus mirabilis is an enterobacterium that causes catheter-associated urinary tract infections (CAUTIs) due to its ability to colonize and form crystalline biofilms on the catheters surface. CAUTIs are very difficult to treat, since biofilm structures are highly tolerant to antibiotics. Phages have been used widely to control a diversity of bacterial species, however, a limited number of phages for P. mirabilis have been isolated and studied. Here we report the isolation of two novel virulent phages, the podovirus vB_PmiP_5460 and the myovirus vB_PmiM_5461, which are able to target, respectively, 16 of the 26 and all the Proteus strains tested in this study. Both phages have been characterized thoroughly and sequencing data revealed no traces of genes associated with lysogeny. To further evaluate the phages’ ability to prevent catheter’s colonization by Proteus, the phages adherence to silicone surfaces was assessed. Further tests in phage-coated catheters using a dynamic biofilm model simulating CAUTIs, have shown a significant reduction of P. mirabilis biofilm formation up to 168 h of catheterization. These results highlight the potential usefulness of the two isolated phages for the prevention of surface colonization by this bacterium. PMID:27446059

    Full Text Available Background: Cardiac resynchronization therapy (CRT device implantation is hampered by difficult placement of the left ventricular (LV lead. We have routinely used a steerable electrophysiology catheter to guide coronary sinus (CS cannulation and facilitate LV lead positioning. The aim of this prospective study is to present our results with this approach in 138 consecutive patients receiving a CRT device over 10 years. Methods: The study included 120 men and 18 women, aged 64.8±11.4 years, with coronary disease (n=63, cardiomyopathy (n=72, or other disease (n=3, and mean ejection fraction of 24.5±4.5%. Devices were implanted for refractory heart failure and dyssynchrony, all but 2 in the presence of left bundle branch block. Implanted devices included biventricular pacemakers (CRT-P (n=33 and cardioverter defibrillators (CRT-D (n=105. Results: Using the electrophysiology catheter, the CS could be engaged in 134 (97.1% patients. In 4 patients failing CS cannulation, a dual-chamber device was implanted in 2, and bifocal right ventricular pacing was effected in 2. Bifocal (n=2 or conventional (n=1 systems were implanted in another 3 patients, in whom the LV lead got dislodged (n=2 or removed because of local dissection (n=1. Thus, finally, a CRT system was successfully established in 131 (94.9% patients. There were 3 patients with CS dissection, of whom 1 was complicated by cardiac tamponade managed with pericardiocentesis. There were no perioperative deaths. During follow-up (31.0±21.2 months, clinical improvement was reported by 108 (82.4% patients. Conclusion: Routine use of an electrophysiology catheter greatly facilitated CS cannulation and successful LV lead placement in ∼95% of patients undergoing CRT system implantation.

    Full Text Available A 57-year-old man with a history of more than 10 years of bronchial asthma and chronic sinusitis complained of double vision which developed 18 days after cardiac tamponade with eosinophil-rich fluid (eosinophils 30%. He had oculomotor nerve palsy, and a blood test revealed eosinophilia (12,700/mm3 and elevation of both C-reactive protein and rheumatoid factor. He was diagnosed as having Churg-Strauss syndrome. His symptoms were relieved by corticosteroid therapy. Our case and previous cases in the literature revealed that oculomotor nerve palsy in Churg-Strauss syndrome is associated with pupil involvement and may be relieved by corticosteroid treatment.

    Purpose: To describe a combined procedure of repositioning and leaving in situ a central venous catheter followed by immediate percutaneous treatment of associated superior vena cava syndrome (SVCS). Methods: Eight patients are presented who have central venous catheter-associated SVCS (n = 6 Hickman catheters, n = 2 Port-a-cath) caused by central vein stenosis (n = 4) or concomitant thrombosis (n = 4). With the use of a vascular snare introduced via the transcubital or transjugular approach, the tip of the central venous catheter could be engaged, and repositioned after deployment of a stent in the innominate or superior vena cava. Results: In all patients it was technically feasible to reposition the central venous catheter and treat the SVCS at the same time. In one patient flipping of the Hickman catheter in its original position provoked dislocation of the released Palmaz stent, which could be positioned in the right common iliac vein. Conclusion: Repositioning of a central venous catheter just before and after stent deployment in SVCS is technically feasible and a better alternative than preprocedural removal of the vascular access

    BACKGROUND: This study aimed to determine whether, in eyes treated for macular hole by vitrectomy and autologous platelet injection, short-term tamponade with SF6 gas was as effective as longer tamponade with C3F8 gas. METHODS: Patients in group 1 (n=31) had vitrectomy, injection of platelet concentrate, and 16% C3F8 gas\\/air exchange. Patients in group 2 (n=31) were similarly treated, except that 23% SF6 gas was used. Group 1 patients were required to posture prone for 2-4 weeks, group 2 for 6 days. RESULTS: All patients had 3 months\\' follow-up. Postoperatively, visual acuity improved faster in group 2. However, the final mean improvement in logMAR acuity was similar in both groups. Intraocular pressure (IOP) spikes occurred in 12 patients in group 2 and in 17 patients in group 1. Posterior subcapsular cataract (PSCC) occurred in 55% of cases in group 1 and in just 37% in group 2. The rate of anatomical success in group 1 was 96.7%, and in group 2, 93.5% (P=1.0). CONCLUSIONS: The combination of SF6 gas, platelet concentrate, and short-term prone posturing gave a degree of anatomical and visual success comparable to that of the group which had longer tamponade. Although no differences were statistically significant, several trends did emerge; in group 2, patients recovered visual acuity faster, had fewer IOP spikes, and there were fewer cases of PSCC formation.

    Full Text Available Purpose : Central venous catheters (CVCs though indispensable in current medical and intensive care treatment, also puts patients at risk of catheter related infection (CRI resulting in increased morbidity and mortality. We analysed the incidence, risk factors, bacteriological profile and antimicrobial susceptibility pattern of the isolates in central venous catheter associated bloodstream infection (CVC-BSI in the intensive care unit (ICU patients and studied the formation of biofilm in CVCs. Materials and Methods: The following case control study included 115 patients with CVC in situ. Quantitative blood cultures (QBC and catheter tip cultures were performed for the diagnoses. Direct catheter staining was done for an early diagnosis by acridine orange (AO and Gram staining methods. Biofilm production in catheters was detected by ′tissue culture plate′ (TCP method. The results were analysed using the computer-based program statistical package for the social sciences (SPSS. Results : In 25/115 patients, definite diagnosis of CVC-BSI was made. The mean age was 48.44 ± 17.34 years (cases vs 40.10 ± 18.24 years (controls and the mean duration of catheterisation was 25.72 ± 8.73 days (cases vs 11.89 ± 6.38 days (controls. Local signs of infection (erythema, tenderness and oozing were found more significantly in CVC-BSI cases. The AO staining was more sensitive and Gram staining of catheters showed higher specificity. Staphylococcus aureus followed by Pseudomonas aeruginosa and non-albicans Candida were common CVC-BSI pathogens. Multidrug-resistant (MDR strains were isolated in bacterial agents of CVC-BSI. Non-albicans Candida and Enterococcus faecalis showed strong biofilm production. Conclusion : The incidence of CVC-BSI was 21.73% and the rate was 14.59 per 1000 catheter days. Prolonged ICU stay and longer catheterisation were major risk factors. S. aureus was isolated most commonly in CVC-BSI cases. The menace of multidrug resistance and

    To date, only silicone oils and gases have the appropriate characteristics for use in vitreo-retinal surgery as vitreous substitutes with intraocular tamponading properties. This preliminary study evaluated the safety and efficacy of medium-chain triglycerides (MCTs) for use as a tamponading agent in minipigs. In 15 minipigs, 15 right eyes underwent vitrectomies followed by injection of MCT tamponade (day 1). Two groups were defined. In Group A (ten eyes), the surgical procedure before MCT injection included induced rhegmatogenous retinal detachment (RRD), retina flattening, and retinopexy. In Group B (five eyes), MCT was injected without inducing RRD; in these eyes, MCT was removed on day 90. Pigs were sacrificed on day 45 (Group A) or 120 (Group B). Eyes were examined on days 1, 5, 15, and 45 in both groups and on days 90 and 120 in Group B. In Group B only, we performed bilateral electroretinography examinations on days 1 and 120, and histological examinations of MCTs and controlateral eyes were performed after sacrifice. In Group A eyes (n = 9; one eye was non-assessable), on day 45, the retina was flat in seven eyes and two RRD detachments were observed in insufficiently MCT-filled eyes. In Group B, electroretinography showed no significant differences between MCT eyes and controls on days 1 or 120. Histological analyses revealed no signs of retinal toxicity. This study showed that MCT tamponade seems to be effective and safe; however, additional studies are needed before it becomes commonly used as a tamponading agent in humans.

    Peripheral venous access in elderly, hospitalized patients is often challenging. The usual alternative is insertion of a central venous catheter, with associated risk for complications. The purpose of this investigation was to determine the relative incidence of phlebitis secondary to lower as compared to upper extremity intravenous catheters (IVCs) and associated risk factors. A non-randomized, observational, cohort-controlled study was carried out. Consecutive patients receiving a lower extremity IVC were enrolled and compared with patients receiving an upper extremity IVC. Patients were followed from insertion until removal of the IVC. The major endpoint was phlebitis. The incidence of phlebitis secondary to upper extremity IVCs was 3/50 (6 %) compared to 5/53 (9.4 %) in lower extremity IVCs (χ(2) Yates = 0.08, p = 0.776). Age, gender, obesity, diabetes mellitus, site (arm versus leg, left versus right), and size of needle were not found to be risk factors for phlebitis according to univariate analysis. None of the patients developed bloodstream infection. In elderly patients with poor venous access, lower extremity IVCs are a reasonable and low-risk alternative to central venous catheters.

    The results of dynamic computed tomography (CT) in 13 patients with intracardiac filling defects and one with a pericardial lipoma are presented. The intracardiac filling defects were due to thrombus in five cases, myxoma in three, hydatid cysts in three, haemangiopericytoma in one and sarcoma in one. These kinds of lesions are well identified by CT which seems to be superior to echocardiography in the characterisation of the components and in the evaluation of the malignant spreading masses.

A prospective, interventional, nonrandomized study. setting: Department of Ophthalmology, Charité - Universitätsmedizin Berlin. One hundred seventeen patients who underwent Descemet membrane endothelial keratoplasty (DMEK). Intraocular pressure (IOP) at the end of the surgery, immediately after filling the anterior chamber with air, categorized into low (20 mm Hg), and the time until partial removal of the air. Rebubbling rates and endothelial cell density over a 3-month follow-up period analyzed by a multivariable Cox regression model and an analysis of covariance model. Thirty-two patients required a rebubbling (27% [95% CI 19%-35%]). Nine patients required more than 1 rebubbling (7% [95% CI 3%-12%]). Compared with normal IOP, lower (HR 8.98 [95% CI 1.07-75.41]) and higher IOP (HR 10.63 [95% CI 1.44-78.27]) increased the risk of requiring a rebubbling (P = .006). Independent of the IOP, an air tamponade duration beyond 2 hours reduced the risk of rebubbling (HR 0.36 [95% CI 0.18-0.71, P = .003]). One month after surgery, the mean endothelial cell loss was 13% (95% CI 2%-25%) and 23% (95% CI 17%-29%) in the group with air tamponade duration of below and above 2 hours, respectively (P = .126). At 3 months after surgery, it was 31% (95% CI 17%-42%) and 42% (95% CI 32%-52%) in the respective groups (P = .229). A postsurgical air tamponade of at least 2 hours with an IOP within the physiological range could help to reduce rebubbling rates. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Purpose: To report a case of macular hole closure after the exchange of a silicone-oil tamponade with gas C3F8 14%. Method: A 64-year-old female patient with a stage IV macular hole underwent a three-port pars-plana vitrectomy and internal limiting membrane peeling. Due to the patient’s chronic illness (respiratory problems, a silicone-oil tamponade was preferred. However, the macula hole was still flat opened four months postoperatively. Therefore, the patient underwent an exchange of silicone oil with gas C3F8 14%. No face-down position was advised postoperatively due to her health problems. Results: Macular hole closure was confirmed with optical coherence tomography six weeks after exchanging the silicone oil with gas. Conclusions: Macular hole surgery using a silicone-oil tamponade has been proposed as treatment of choice for patients unable to posture. In our case, the use of a long-acting gas (C3F8 14%, even without posturing, proved to be more effective.

    To evaluate the long-term outcomes of a surgical technique using a sutureless bovine pericardial patch graft for the implantation of an Ahmed glaucoma valve (AGV). 
 This was a pilot study on patients with primary open-angle glaucoma refractory to repeated surgical filtering procedures. All patients underwent AGV implant technique using a sutureless bovine pericardial patch graft. The pericardial membrane was cut using an ordinary corneal trephine with a diameter of 9.0 or 10.0 mm. The anterior part of the tube was covered with the graft and kept in place with fibrin glue. Subsequently, the cap was stitched all around the tube and the dissected conjunctiva was laid over it. Intraocular pressure (IOP) and complications were evaluated 1 week and 1, 3, 6, 12, and 24 months after surgery.
 The procedure was used to treat 20 eyes of 20 consecutive patients (12 men and 8 women: mean age [SD] 64.8 [7.8] years). Mean IOP was 28.1 mm Hg (SD 4.9) at baseline and decreased to 14.9 mm Hg (SD 1.5) 24 months after surgery (pendophthalmitis were recorded.
 The results suggest that the sutureless technique using a bovine pericardial graft patch is a safe and rapid procedure for AGV implantation.

    Full Text Available Insertion of central venous catheter is an accepted method for hemodynamic monitor-ring, drug and fluid administration, intravenous access, hemodialysis and applying cardiac pace-maker in hospitalized patients. This procedure can be associated with severe complications. The aim of this article is to provide a practical approach to prevent catheter malposition in states that the guide wire will not pass freely.During central venous insertion in internal jugular vein using modified seldinger technique, when after venous insertion, the passage of the guide wire shows difficulties and don’t pass freely, insertion of an intravenous cannula over the wire and re-insertion of the wire can help to prevent malposition of the wire and the catheter. Use of an intravenous cannula over the guide, in situations that the guide wire cannot pass freely among the needle inserted in internal jugular vein, and re-insertion of the guide can probably prevent or reduce the tissue or vascular trauma and the associated complica-tions. This simple maneuver can be helpful in difficult cases especially in cardiac surgery patients who receive high dose heparin and it is necessary to avoid traumatize-tion of carotid artery.

  12. Role of echocardiography for catheter-based management of valvular heart disease.

    2017-01-01

    Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures. Severe hypotension after TAVR is a life-threatening emergency. Rapid assessment and diagnosis in the catheterization or hybrid laboratory is essential for safety and a positive outcome. Possible diagnoses in this critical situation would include severe left ventricular dysfunction due to coronary obstruction, cardiac tamponade, aortic rupture, acute severe aortic and/or mitral valve regurgitation, and hypovolemia due to bleeding. Although new types of TAVR valves reduce para-valvular aortic regurgitation (AR) significantly, it is still important to judge the severity of para-valvular AR correctly in the laboratory. As for mitral clip procedure, TEE is vital for guiding and monitoring the entire process. Accurate identification of the location and the geometry of the regurgitant orifice is necessary for proper placement of the clip. Real-time 3D TEE provides helpful en face view of the mitral valve and clip together to this end. Residual mitral regurgitation (MR) after the first clip is not uncommon. Quick and precise imaging of the residual MR (location and severity) with TEE is extremely important for the interventionist to place the second clip and possibly third clip properly. After the completion of the clip procedure, mitral valve stenosis and also iatrogenic atrial septal defect need to be checked by TEE. Echocardiography, especially TEE, is also vital for the success of other newer trans-catheter

    A patient with endothelial dystrophy was treated with Descemet stripping automated endothelial keratoplasty (DSAEK) combined with cataract extraction and implantation of a hydrophilic intraocular lens (IOL, Lentis-L312, Oculentis) but visual acuity dropped from 0.15 logMAR to 0.52 logMAR 18 months later due to calcification of the IOL. With new methods of lamellar corneal transplantation being used more frequently the number of necessary anterior chamber tamponades with air/gas are increasing. In cataract cases in which a gas tamponade and transplantation might be necessary later on (cornea guttata), hydrophilic IOLs should be avoided.

Patients who were diagnosed with placenta accreta or increta preoperatively and intraoperatively and treated with Bakri balloon tamponade (Group 1) or caesarean hysterectomy (Group 2) were compared in regards to the postoperative results. Among the 36 patients diagnosed with placenta accreta or increta, 19 patients were treated with Bakri balloon tamponade while 17 cases were treated with hysterectomy. Intraoperative blood loss amount was 1794 ± 725 ml in G1, which was lower than that in G2 (2694 ± 893 ml). Blood transfusion amount was 2.7 ± 2.6 units in G1, lower than that in G2 (5.7 ± 2.4 units), too. Operation time was 64.5 ± 29 min and 140 ± 51 min in G1 and G2, respectively, showing significant differences between two groups. The success rate of Bakri balloon was determined as 84.21%. In conclusion, cases with placenta accreta/increta, with predicted placental detachment who are willing to preserve fertility, application of uterine balloon tamponade devices before the hysterectomy is encouraging with its advantages compared with the hysterectomy. Impact statement What is already known on this subject: Invasive placental anomalies are the most common indication of postpartum hysterectomy. Recently, uterine balloon tamponade was also included in the treatment modalities of postpartum haemorrhage.This study aimed to compare the postoperative results of UBT or hysterectomy for patients with placenta accreta and increta. What the results of this study add: In this study, the total amount of blood loss was higher in the caesarean hysterectomy group when compared with the Bakri balloon tamponade group. The mean transfusion requirement, mean operation time and hospitalisation period was significantly longer in the caesarean hysterectomy group. The success

    Full Text Available Heparin, a commonly used anticoagulant agent, is frequently used in patients undergoing hemodialysis. As with most medications, heparin has a significant side effect profile. Two of its most important side effects, major bleeding and hyperkalemia, may be devastating without immediate diagnosis and treatment. Major bleeding such as gastrointestinal, genitourinary or intracranial bleeding is occasionally encountered and rarely neglected. However, heparin-induced cardiac tamponade is rarely encountered and may be easily overlooked. Another side effect, heparin-induced hyperkalemia, an unusual but well-described side effect, is frequently forgotten until life-threatening arrhythmia has occurred. We report a case involving a 40-year-old male patient with uremia, who had received heparin for 10 days for deep vein thrombosis in the left lower extremity. Hemopericardium with cardiac tamponade and life-threatening hyperkalemia were both noted in this patient.

    Fixed pericardial tissue is commonly used for commercially available xenograft valve implants, and has proven durability, but lacks the capability to remodel and grow. Decellularized porcine pericardial tissue has the promise to outperform fixed tissue and remodel, but the decellularization process has been shown to damage the collagen structure and reduce mechanical integrity of the tissue. Therefore, a comparison of uniaxial tensile properties was performed on decellularized, decellularized-sterilized, fixed, and native porcine pericardial tissue, versus native valve leaflet cusps. The results of non-parametric analysis showed statistically significant differences (ptesting of the tissues showed no statistical difference between decellularized or decell-sterilized tissue compared to native cusps (p>0.05). SEM confirmed that valvular endothelial and interstitial cells colonized the decellularized pericardial surface when seeded and grown for 30 days in static culture. Collagen assays and TEM analysis showed limited reductions in collagen with processing; yet, GAG assays showed great reductions in the processed pericardium relative to native cusps. Decellularized pericardium had comparatively lower mechanical properties amongst the groups studied; yet, the stiffness was comparatively similar to the native cusps and demonstrated a lack of cytotoxicity. Suture retention, accelerated wear, and hydrodynamic testing of prototype decellularized and decell-sterilized valves showed positive functionality. Sterilized tissue could mimic valvular mechanical environment in vitro, therefore making it a viable potential candidate for off-the-shelf tissue engineered valvular applications.

    A 37-year-old female yellow-naped Amazon parrot (Amazona auropalliata) was presented with a history of lethargy, inappetence, and decreased vocalizations. On examination, the coelom was moderately distended and palpated fluctuant, and the heart was muffled on auscultation. Coelomic ultrasound, coelomocentesis, and radiographs were performed and revealed an enlarged cardiac silhouette and marked coelomic effusion. Pericardial effusion was confirmed by echocardiography. A well-circumscribed, hyperechoic soft tissue density was observed at the level of the right atrium on initial echocardiography; however, a cardiac mass was not identified by computed tomography scan or repeat echocardiograms. Ultrasound-guided pericardiocentesis was performed under anesthesia, and cytology results were consistent with hemorrhage; no neoplastic cells were identified. A repeat echocardiogram 4 days after pericardiocentesis revealed recurrence of the pericardial effusion. Due to the grave prognosis, the owners declined endoscopic pericardiectomy, and the patient died the following day. On postmortem examination, the pericardial surface of the heart was covered in a white to yellow, multinodular mass layer. Histologic analysis revealed a multinodular mass extending from the atria, running along the epicardium distally, and often extending into the myocardium. Neoplastic cells present in the heart mass and pericardium did not stain with a Churukian-Schenk stain, and thyroglobulin immunohistochemistry was negative. Cytokeratin and vimentin stains showed positive expression in the neoplastic cells within the mass. These results are consistent with a diagnosis of mesothelioma. This is the first report of mesothelioma in a psittacine bird.

    Castleman's disease is an uncommon disorder characterized by benign proliferation of the lymphoid tissue that occurs most commonly in the mediastinum. Although unusual locations and manifestations have been reported, involvement of the renal parenchyma and sinus, and moreover, manifestations as cardiac tamponade are extremely rare. Here, we present a rare case of Castleman's disease in the renal parenchyma and sinus that also accompanied cardiac tamponade.

    Four different interventions were examined in dogs with cardiac tamponade. Infusion of 216 to 288 ml saline solution into the pericardium reduced cardiac output from 3.5 +/- 0.3 to 1.7 +/- 0.2 liters/min as systemic vascular resistance increased from 4,110 +/- 281 to 6,370 +/- 424 dynes . s . cm-5. Left ventricular epicardial and endocardial blood flows were 178 +/- 13 and 220 +/- 12 ml/min per 100 g, respectively, and decreased to 72 +/- 14 and 78 +/- 11 ml/min per 100 g with tamponade. Reductions of 25 to 65% occurred in visceral and brain blood flows and in a composite brain sample. Cardiac output during tamponade was significantly increased by isoproterenol, 0.5 microgram/kg per min intravenously; hydralazine, 40 mg intravenously; dextran infusion or combined hydralazine and dextran, but not by amrinone. Total systemic vascular resistance was reduced by all interventions. Left ventricular epicardial flow was increased by isoproterenol, hydralazine and the hydralazine-dextran combination. Endocardial flow was increased by amrinone and the combination of hydralazine and dextran. Right ventricular myocardial blood flow increased with all interventions except dextran. Kidney cortical and composite brain blood flows were increased by both dextran alone and by the hydralazine-dextran combinations. Blood flow to small intestine was increased by all interventions as was that to large intestine by all except amrinone and hydralazine. Liver blood flow response was variable. The most pronounced hemodynamic and tissue perfusion improvements during cardiac tamponade were effected by combined vasodilation-blood volume expansion with a hydralazine-dextran combination. Isoproterenol had as dramatic an effect but it was short-lived. Amrinone was the least effective intervention

    To discover the incidence of central venous catheters (tunnelled, subcutaneous and PICC) in patients with onco-hematological conditions, hospitalized in the Hematology or Transplantations of Hematopoietic Stem Cells Units, in two tertiary care hospitals. A cross-sectional, descriptive study form was developed in order to gather sociodemographic, clinical data as well as complications and follow-up of the care protocol. Each catheter was assigned a correlative identification number. Information was collected on 366 catheters: 185 in the University Hospital Ramón y Cajal (HURYC), 80 tunnelled, 40 subcutaneous venous access and 65 PICC, and 181 in the University Hospital Gregorio Marañón (HUGM), 101 tunnelled and 80 subcutaneous venous access. Major complications in the tunnellized were infections (13.7% in HURYC vs. 6.8% in HUGM - p<0.001) and occlusions (at least once in 3.8% vs. 21.8%). In subcutaneous venous access, infections were confirmed in 5% in HURYC vs. 1.2% in HUGM. There were occlusions at least once in 10% in HUGM and no other significant complications were detected. Regarding PICC, information was only collected in HURYC, where complications were phlebitis 10.8%, thrombosis 7.7%, confirmed or suspected infection 4.6%, occlusion at least once 7.7%. Differences between hospitals with regard to major complications, infection and occlusion may be related to different care protocol. We need to stress the high incidence of phlebitis and thrombosis in PICC catheters, compared with data of lower incidence of other papers. Copyright © 2015 Elsevier España, S.L.U.

    Pericardial effusion is an important late toxicity after concurrent chemoradiotherapy (CCRT) for locally advanced esophageal cancer. We investigated the clinical and dosimetric factors that were related to pericardial effusion among patients with thoracic esophageal cancer who were treated with definitive CCRT using the two opposed fields technique (TFT) or the four-field technique (FFT), as well as the effectiveness of FFT. During 2007-2015, 169 patients with middle and/or lower thoracic esophageal cancer received definitive CCRT, and 94 patients were evaluable (51 FFT cases and 43 TFT cases). Pericardial effusion was observed in 74 patients (79%) and appeared at 1-18.5 months (median: 5.25 months) after CCRT. The 1-year incidences of pericardial effusions were 73.2% and 76.7% in the FFT and TFT groups, respectively (P = 0.6395). The mean doses to the pericardium were 28.6 Gy and 31.8 Gy in the FFT and TFT groups, respectively (P = 0.0259), and the V40 Gy proportions were 33.5% and 48.2% in the FFT and TFT groups, respectively (P effusion was not observed in patients with a pericardial V40 Gy of effusion after CCRT were similar in both groups. As symptomatic pericardial effusion was not observed in patients with a pericardial V40 Gy of effusion.

Lenses were reserved in 78 eyes and were taken away in 40 eyes among which intraocular lens were implanted in 17 eyes. There were 39 eyes in which the filling time of silicone was no more than 6 months while 79 eyes in which the filling time was more than 6 months. The follow-up time was(16.2±4.9months. Primary and secondary glaucoma were excluded before the vitrectomy. Silicone oil glaucoma(SOGwas diagnosed when intraocular pressure(IOPwas measured higher than 21mmHg(1mmHg=0.133kPathree times in succession at least 1 month after silicone oil tamponade and inflammation and neovascular glaucoma should be excluded. Anti-glaucoma drugs were administrated once SOG was diagnosed. If the IOP was not controlled after 2 weeks, the silicone oil was taken away. If the IOP was still high, the anti-glaucoma surgery was operated. The data was analyzed by the SPSS 16.0 software using a binary logistic regression analysis. RESULTS: Among the 32 eyes of SOG, lenses were removed in 16 eyes(50%. The filling time of silicone oil was more than 6 months in 27 eyes(84.4%and silicone oil emulsion happened in 20 eyes(62.5%. IOP returned normal in 17 eyes after administrating anti-glaucoma medication within 2 weeks. Silicone oils were taken away in 15 eyes.

    Continuous brachial plexus catheters are often used to decrease pain following elbow surgery. This investigation aimed to assess the rate of early failure of infraclavicular (IC) and axillary (AX) nerve catheters following elbow surgery. Retrospective study. Postoperative recovery unit and inpatient hospital floor. 328 patients who received IC or AX nerve catheters and underwent elbow surgery were identified by retrospective query of our institution's database. Data collected included unplanned catheter dislodgement, catheter replacement rate, postoperative pain scores, and opioid administration on postoperative day 1. Catheter failure was defined as unplanned dislodging within 24 h of placement or requirement for catheter replacement and evaluated using a covariate adjusted model. 119 IC catheters and 209 AX catheters were evaluated. There were 8 (6.7%) failed IC catheters versus 13 (6.2%) failed AX catheters. After adjusting for age, BMI, and gender there was no difference in catheter failure rate between IC and AX nerve catheters (p = 0.449). These results suggest that IC and AX nerve catheters do not differ in the rate of early catheter failure, despite differences in anatomic location and catheter placement techniques. Both techniques provided effective postoperative analgesia with median pain scores < 3/10 for patients following elbow surgery. Reasons other than rate of early catheter failure should dictate which approach is performed. Copyright © 2018. Published by Elsevier Inc.

  8. The dangers of long-term catheter drainage.

    Science.gov (United States)

    Lowthian, P

    There are many dangers associated with long-term urinary bladder drainage by catheter. For various reasons, the choice of catheter is important, and its initial insertion can be particularly hazardous. All catheterizations should, however, be safer when there is some urine (or other fluid) in the bladder. The appropriate choice of drainage system attached to the catheter can delay bacterial invasion of the bladder. Great care is needed to prevent blockage of the system, particularly when bacteriuria is present. Recent evidence indicates that some bacteria encourage the development of encrustations, so that, in some circumstances, catheters may become blocked within 24 hours. This, together with other considerations, strongly suggests that indwelling catheters should be changed at intervals of not more than 5 days. The practical implications of this are considered, as are the benefits that may accrue. Accidental catheter traction is another danger, and some possible methods of avoiding this are discussed. Finally, the need for a new kind of drainage-bag support is highlighted.

    Centers for Medicare and Medicaid Services have determined that chronic dialysis units should have 45%. A multidisciplinary program was established with goals of decreasing catheter rates in order to decrease central line-associated bloodstream infections, decrease mortality associated with central line-associated bloodstream infection, decrease hospital days, and provide savings to the healthcare system. We collected the catheter rates within three dialysis centers served over a 5-year period. Using published data surrounding the incidence and related costs of central line-associated bloodstream infection and mortality per catheter day, the number of central line-associated bloodstream infection events, the costs, and the related mortality could be determined prior to and after the initiation of the dialysis access program. An organized dialysis access program resulted in a 82% decrease in the number of central venous catheter days which lead to a concurrent reduction in central line-associated bloodstream infection and deaths. As a result of creating an access program, central venous catheter rates decreased from an average rate of 45% to 8%. The cost savings related to the program was calculated to be over US$5 million. The decrease in the number of mortalities is estimated to be between 13 and 27 patients. We conclude that a formalized access program decreases catheter rates, central line-associated bloodstream infection, and the resultant hospitalizations, mortality, and costs. Areas with high hemodialysis catheter rates should develop access programs to better serve their patient population.

    The Drosophila heart, composed of discrete subsets of cardioblasts and pericardial cells, undergoes Hox-triggered anterior-posterior morphogenesis, leading to a functional subdivision into heart proper and aorta, with its most anterior part forming a funnel-shaped cardiac outflow. Cardioblasts differentiate into Tin-positive 'working myocytes' and Svp-expressing ostial cells. However, developmental fates and functions of heart-associated pericardial cells remain elusive. Here, we show that the pericardial cells that express the transcription factor Even Skipped adopt distinct fates along the anterior-posterior axis. Among them, the most anterior Antp-Ubx-AbdA - negative cells form a novel cardiac outflow component we call the outflow hanging structure, whereas the Antp-expressing cells differentiate into wing heart precursors. Interestingly, Hox gene expression in the Even Skipped-positive cells not only underlies their antero-posterior diversification, but also influences heart morphogenesis in a non-cell-autonomous way. In brief, we identify a new cardiac outflow component derived from a subset of Even Skipped-expressing cells that stabilises the anterior heart tip, and demonstrate non-cell-autonomous effects of Hox gene expression in the Even Skipped-positive cells on heart morphogenesis. © 2018.

    BACKGROUND: Vitrectomy and gas tamponade has become a recognised technique for the treatment of macular holes. In an attempt to improve the anatomic and visual success of the procedure, various adjunctive therapies--cytokines, serum, and platelets--have been employed. A consecutive series of 85 eyes which underwent macular hole surgery using gas tamponade alone, or gas tamponade with either the cytokine transforming growth factor beta 2 (TGF-beta 2) or autologous platelet concentrate is reported. METHODS: Twenty eyes had vitrectomy and 20% SF6 gas tamponade; 15 had vitrectomy, 20% SF6 gas, and TGF-beta 2; 50 had vitrectomy, 16% C3F8 gas tamponade, and 0.1 ml of autologous platelet concentrate prepared during the procedure. RESULTS: Anatomic success occurred in 86% of eyes, with 96% of the platelet treated group achieving closure of the macular hole. Visual acuity improved by two lines or more in 65% of the SF6 only group, 33% of those treated with TGF-beta 2 and in 74% of the platelet treated group. In the platelet treated group 40% achieved 6\\/12 or better and 62% achieved 6\\/18 or better. The best visual results were obtained in stage 2 holes. CONCLUSION: Vitrectomy for macular holes is often of benefit and patients may recover good visual acuity, especially early in the disease process. The procedure has a number of serious complications, and the postoperative posturing requirement is difficult. Patients need to be informed of such concerns before surgery.

    We studied the influence of joint effusion on juxtaarticular vascularity and bone metabolism of the immature knee in puppies by dynamic and static {sup 99m}Tc-diphosphonate scintimetry. Unilateral joint tamponade of 10 KPa (75 mmHg), introduced by intraarticular dextran-70 infusion, resulted in quantitatively similar scintimetric changes in an angiographic Phase I (0-20 sec), a blood pool Phase II (20-256 sec), and a bone-uptake Phase III (2h). The uptake was reduced by 20 percent in the distal femoral epiphysis, by 15 percent in the distal femoral growth plate in Phase II-III, and by 8 percent in the proximal tibial growth plate in Phase III. The main part of scintimetric changes during joint tamponade could be ascribed to altered epiphyseal and metaphyseal intraosseous hemodynamics. (author).

    Despite the technological advance in 3-dimensional (3D) mapping, radiation exposure during catheter ablation of atrial fibrillation (AF) continues to be a major concern in both patients and physicians. Previous studies reported substantial radiation exposure (7369-8690 cGy cm) during AF catheter ablation with fluoroscopic settings of 7.5 frames per second (FPS) under 3D mapping system guidance. We evaluated the efficacy and safety of a low-frame-rate fluoroscopy protocol for catheter ablation for AF.Retrospective analysis of data on 133 patients who underwent AF catheter ablation with 3-D electro-anatomic mapping at our institute from January 2014 to May 2015 was performed. Since January 2014, fluoroscopy frame rate of 4-FPS was implemented at our institute, which was further decreased to 2-FPS in September 2014. We compared the radiation exposure quantified as dose area product (DAP) and effective dose (ED) between the 4-FPS (n = 57) and 2-FPS (n = 76) groups.The 4-FPS group showed higher median DAP (599.9 cGy cm; interquartile range [IR], 371.4-1337.5 cGy cm vs. 392.0 cGy cm; IR, 289.7-591.4 cGy cm; P FPS group. No major procedure-related complications such as cardiac tamponade were observed in either group. Over follow-up durations of 331 ± 197 days, atrial tachyarrhythmia recurred in 20 patients (35.1%) in the 4-FPS group and in 27 patients (35.5%) in the 2-FPS group (P = .96). Kaplan-Meier survival analysis revealed no significant different between the 2 groups (log rank, P = .25).In conclusion, both the 4-FPS and 2-FPS settings were feasible and emitted a relatively low level of radiation compared with that historically reported for DAP in a conventional fluoroscopy setting.

    BACKGROUND: Catheter ablation for atrial fibrillation (AF) is an important but expensive procedure that is the subject of some debate. Physicians´ attitudes towards catheter ablation may influence promotion and patient acceptance. This is the first study to examine the attitudes of Danish...... cardiologists towards catheter ablation for AF, using a nationwide survey. METHODS AND RESULTS: We developed a purpose-designed questionnaire to evaluate attitudes towards catheter ablation for AF that was sent to all Danish cardiologists (n = 401; response n = 272 (67.8%)). There was no association between...... attitudes towards ablation and the experience or age of the cardiologist with respect to patients with recurrent AF episodes with a duration of 7 days and/or need for cardioversion. The majority (69%) expected a recurrence of AF after catheter ablation in more than 30% of the cases...

    Burton, Kirsteen R.; Guo, Lancia L. Q.; Tan, Kong T.; Simons, Martin E.; Sniderman, Kenneth W.; Kachura, John R.; Beecroft, John R.; Rajan, Dheeraj K.

    2012-01-01

    Purpose: To determine the patency rates of and factors associated with increased risk of patency failure in patients with femoral vein tunneled hemodialysis catheters. Methods: All femoral tunneled catheter insertions from 1996 to 2006 were reviewed, during which time 123 catheters were inserted. Of these, 66 were exchanges. Patients with femoral catheter failure versus those with femoral catheter patency were compared. Confounding factors, such as demographic and procedural factors, were incorporated and assessed using univariate and multivariable Cox proportional hazards regression analyses. Results: Mean catheter primary patency failure time was 96.3 days (SE 17.9 days). Primary patency at 30, 60, 90, and 180 days was 53.8%, 45.4%, 32.1%, and 27.1% respectively. Crude rates of risk of catheter failure did not suggest a benefit for patients receiving catheters introduced from one side versus the other, but more cephalad location of catheter tip was associated with improved patency. Multivariate analysis showed that patients whose catheters were on the left side (p = 0.009), were of increasing age at the time of insertion (p = 0.002) and that those who had diabetes (p = 0.001) were at significantly greater risk of catheter failure. The catheter infection rate was 1.4/1000 catheter days. Conclusion: Patients who were of a more advanced age and had diabetes were at greater risk of femoral catheter failure, whereas those who received femoral catheters from the right side were less at risk of catheter failure.

    Catheter-associated urinary tract infections (CA-UTI) are estimated to be the most frequent nosocomial infections (40%). A catheter is introduced to 10-25% of inpatients, and is often left on site for a long period of time. We carried out a prospective study on inpatients of our Internal Medicine ward to assess the incidence of CA-UTI under the implementation of corrective action. All inpatients who underwent introduction of a urinary catheter upon or after admission to our ward were included in the study. Patients with bacteriuria or positive urine culture before catheterization, others with less than 24 hours catheterism, or bearing a catheter on admission were all excluded from the study. CA-UTI diagnosis was assessed on the basis of CDC 2009 guidelines. The investigation was held between June 2010 and March 2013 in five steps or phases. In the first phase open circuit drainage catheterism was used, in the second phase close circuit drainage catheterism was introduced, while in the third phase disposable lubrification was added to closed circuit drainage catheterism. In the next step (phase 4) we introduced number of days of catheterism control and nurse training; in the last phase (5) emptying urine collection bags on a container was added. In phase 1 we estimated six UTIs out of 18 patients (incidence 33%), in phase 2 we had four infections out of 10 patients (40%). Given the results, we had to reflect on the quality of the procedures of catheter positioning and management . Where feasible, we improved technical practices and during follow-up there was evidence of CA-UTI in 10 patients over 25 (phase 3, 40%), and eight infections over 25 (phase 4, 32%). Once all these steps had been implemented, in phase 5 we determined a sharp reduction in CA-UTI (2 patients over 27, or 7.5%, p=0.025). This improvement was particularly evident in the rate of infection per days of catheter, which was reduced from 43.4/1000 to 13.6/1000. Although the statistical power of the

    Full Text Available Abstract Background Catheter ablation of the pulmonary veins has become accepted as a standard therapeutic approach for symptomatic paroxysmal atrial fibrillation (AF. However, there is some evidence for an ablation associated (silent stroke risk, lowering the hope to limit the stroke risk by restoration of rhythm over rate control in AF. The purpose of the prospective randomized single-center study "Mesh Ablator versus Cryoballoon Pulmonary Vein Ablation of Symptomatic Paroxysmal Atrial Fibrillation" (MACPAF is to compare the efficacy and safety of two balloon based pulmonary vein ablation systems in patients with symptomatic paroxysmal AF. Methods/Design Patients are randomized 1:1 for the Arctic Front® or the HD Mesh Ablator® catheter for left atrial catheter ablation (LACA. The predefined endpoints will be assessed by brain magnetic resonance imaging (MRI, neuro(psychological tests and a subcutaneously implanted reveal recorder for AF detection. According to statistics 108 patients will be enrolled. Discussion Findings from the MACPAF trial will help to balance the benefits and risks of LACA for symptomatic paroxysmal AF. Using serial brain MRIs might help to identify patients at risk for LACA-associated cerebral thromboembolism. Potential limitations of the study are the single-center design, the existence of a variety of LACA-catheters, the missing placebo-group and the impossibility to assess the primary endpoint in a blinded fashion.

    ABSTRACT Objective: to determine the incidence rate and risk factors for the nursing-sensitive indicators phlebitis and infiltration in patients with peripheral venous catheters (PVCs). Method: cohort study with 110 patients. Scales were used to assess and document phlebitis and infiltration. Socio-demographic variables, clinical variables related to the PVC, medication and hospitalization variables were collected. Descriptive and inferential analysis and multivariate logistic models were used. Results: the incidence rate of phlebitis and infiltration was respectively 43.2 and 59.7 per 1000 catheter-days. Most PVCs with these vascular traumas were removed in the first 24 hours. Risk factors for phlebitis were: length of hospital stay (p=0.042) and number of catheters inserted (p<0.001); risk factors for infiltration were: piperacillin/tazobactan (p=0.024) and the number of catheters inserted (p<0.001). Conclusion: the investigation documented the incidence of nursing-sensitive indicators (phlebitis and infiltration) and revealed new risk factors related to infiltration. It also allowed a reflection on the nursing care necessary to prevent these vascular traumas and on the indications and contraindications of the PVC, supporting the implementation of the PICC as an alternative to PVC.

    Thiazolidinedione-8 (TZD-8) is an anti-quorum-sensing molecule that has the potential to effectively prevent catheter-associated urinary tract infections, a major healthcare challenge. Sustained-release drug-delivery systems can enhance drugs' therapeutic potential, by maintaining their therapeutic level and reducing their side effects. Varnishes for sustained release of TZD-8 based on ethylcellulose or ammonio methacrylate copolymer type A (Eudragit(®) RL) were developed. The main factors affecting release rate were found to be film thickness and presence of a hydrophilic or swellable polymer in the matrix. The release mechanism of ethylcellulose-based systems matched the Higuchi model. Selected varnishes were retained on catheters for at least 8 days. Sustained-release delivery systems of TZD-8 were active against Candida albicans biofilms. The present study demonstrates promising results en route to developing applications for the prevention of catheter-associated infections. Copyright © 2015 Elsevier B.V. All rights reserved.

    The Centers for Disease Control and Prevention recently updated the surveillance definition of catheter-associated urinary tract infection to include only urine culture bacteria of at least 1 × 10(5) colony-forming units/mL. Our findings suggest that the new surveillance definition may fail to capture clinically meaningful catheter-associated urinary tract infections.

    There is evidence to suggest that the cellular components of homografts and bioprosthetic xenografts may contribute to calcification or immunogenic reactions. A four-step detergent and enzymatic extraction process has been developed to remove cellular components from bovine pericardial tissue. The process results in an acellular matrix material consisting primarily of elastin, insoluble collagen, and tightly bound glycosaminoglycans. Light and electron microscopy confirmed that nearly all cellular constituents are removed without ultrastructural evidence of damage to fibrous components. Collagen denaturation temperatures remained unaltered. Biochemical analysis confirmed the retention of collagen and elastin and some differential extraction of glycosaminoglycans. Low strain rate fracture testing and high strain rate viscoelastic characterization showed that, with the exception of slightly increased stress relaxation, the mechanical properties of the fresh tissue were preserved in the pericardial acellular matrix. Crosslinking of the material in glutaraldehyde or poly(glycidyl ether) produced mechanical changes consistent with the same treatments of fresh tissue. The pericardial acellular matrix is a promising approach to the production of biomaterials for heart valve or cardiovascular patching applications.

    Objective: To investigate the alterations of plasma endothelin-1 (ET-1) and nitric oxide (NO) post the selective pericardial devascularization in patients with hepatic portal hypertension,and to investigate the relationship between such alterations with illness and therapeutic effects. Methods: Before treatment,plasma ET-1 and NO contents were determined by radioimmunoassay (RIA) and Griss method respectively in 92 patients with hepatic portal hypertension. One day and three weeks after operation, 66 operated cases with selective pericardial devascularization in patients with hepatic protal hypertension were also determined the levels of plasma ET-1 and NO with RIA. Results: The levels of plasma ET-1 and NO were increased in 92 patients with hepatic portal hypertension, and which closely related to the stage of illness. Post effective selective pericardial devascularization the high levels of plasma ET-1 and No were improved and were closely returned to normal after 3 week's. Conclusion: Clinical detection of plasma ET-1 and NO levels were useful for assessment of the therapeutic effects of selective pericardial devascularization in patients with hepatic portal hypertension.

    Full Text Available Catheter insertion for intravenous hyperalimentation is a commonly and widely used clinical technique. When compared with the incidence of complications associated with insertions into the internal jugular vein or the subclavian vein, complications associated with insertions into the femoral vein are less frequent. In this paper, we describe a very rare complication of femoral vein catheter insertion—namely, catheter displacement into the inferior epigastric vein.

    Long-term catheterization inevitably leads to a catheter-associated bacteriuria caused by multispecies bacterial biofilms growing on and in the catheters. The overall goal of the presented study was (1) to unravel bacterial community structure and function of such a uropathogenic biofilm and (2) to elucidate the interplay between bacterial virulence and the human immune system within the urine. To this end, a metaproteomics approach combined with in vitro proteomics analyses was employed to investigate both, the pro- and eukaryotic protein inventory. Our proteome analyses demonstrated that the biofilm of the investigated catheter is dominated by three bacterial species, that is, Pseudomonas aeruginosa, Morganella morganii, and Bacteroides sp., and identified iron limitation as one of the major challenges in the bladder environment. In vitro proteome analysis of P. aeruginosa and M. morganii isolated from the biofilm revealed that these opportunistic pathogens are able to overcome iron restriction via the production of siderophores and high expression of corresponding receptors. Notably, a comparison of in vivo and in vitro protein profiles of P. aeruginosa and M. morganii also indicated that the bacteria employ different strategies to adapt to the urinary tract. Although P. aeruginosa seems to express secreted and surface-exposed proteases to escape the human innate immune system and metabolizes amino acids, M. morganii is able to take up sugars and to degrade urea. Most interestingly, a comparison of urine protein profiles of three long-term catheterized patients and three healthy control persons demonstrated the elevated level of proteins associated with neutrophils, macrophages, and the complement system in the patient's urine, which might point to a specific activation of the innate immune system in response to biofilm-associated urinary tract infections. We thus hypothesize that the often asymptomatic nature of catheter-associated urinary tract infections

    This first-in-human study evaluated the safety and technical feasibility of the Tempo temporary cardiac pacing lead (BioTrace Medical), which includes a novel fixation mechanism and soft tip. Complications of temporary pacing leads include dislodgment, arrhythmias, and ventricular perforation. Temporary pacing applications have increased with transcatheter aortic valve replacement (TAVR) growth, for rapid pacing during balloon valvuloplasty (BAV) and valve deployment, and for periprocedural bradyarrhythmia support. Eligible patients required temporary pacing for TAVR, BAV, or electrophysiology (EP) procedures. Transthoracic echocardiograms were obtained at baseline and 24 hours after lead removal. Safety was defined as freedom from pericardial effusion requiring intervention or evidence of tamponade. Technical feasibility involved successful intracardiac delivery and pace capture. Additional evaluations included pacing threshold (PCT), rapid pacing, dislodgment, or sustained ventricular arrhythmias. Follow-up was to 30 days. Twenty-five patients (60% female; mean age, 64 ± 19 years) underwent 13 TAVRs (7 Sapien 3 valves [Edwards Lifesciences], 4 CoreValves [Medtronic], and 2 Lotus valves [Boston Scientific]), 11 EP procedures, and 1 BAV at two New Zealand centers from January 2016 to June 2016. Safety was met in all patients, with no device-related adverse events. Technical feasibility was achieved in 23 cases (92%); 2 patients had unsuitable anatomy. No patient had lead dislodgment or sustained ventricular arrhythmias, and the final procedural PCT was 0.7 ± 0.5 mA. Rapid pacing was successful in all cases. Five patients had successful postprocedural use up to 5 days. This first-in-human study demonstrates the safety and technical feasibility of the Tempo lead, providing stable periprocedural temporary pacing support.

    In 72 episodes of suspected or proven Hickman-catheter-associated infection occurring in 59 patients with various hematological disorders, patients were assigned to treatment with either vancomycin or teicoplanin in a randomized nonblinded prospective study. Of 60 episodes evaluable for response, 28 were treated with vancomycin and 32 were treated with teicoplanin. Sixteen infective episodes were microbiologically documented in the vancomycin group, and twenty-one were microbiologically documented in the teicoplanin group. Microbiologically and clinically documented infections treated with vancomycin had an 80% response rate, compared with a 69% response rate for those treated with teicoplanin (P = 0.316). Adverse events occurred in nine (25%) of the episodes in the vancomycin group, compared with three (8%) in the teicoplanin group (P = 0.044). Teicoplanin may provide an effective alternative to vancomycin in the treatment of Hickman-catheter-associated infection in patients with hematological malignancies.

Methods: Retrospective information was obtained from medical records of all patients who were diagnosed with echocardiographic pericardial effusions. Results: We studied 62 medical records of patients with echocardiographic pericardial effusions. We obtained medical records of 28 (45.2% patients with mild effusion, 19 (30.6% with moderate effusion and 15 (24.2% with severe effusion. Fourteen patients (22.6% showed inflammatory signs of pericarditis. Inflammatory signs had an Odds Ratio of 5.1. (CI 95% 1.28 to 23 wich was significant (p = 0.006. Uremia was the most common diagnosis in all patients (22.6% followed by metastatic tumors (14.5%, pyogenic pericarditis (11.3%, acute idiopathic pericarditis (11.3% and others. Conclusions: In almost all patients, etiology of pericardial effusion is the same of the underlying condition, but if the cause is unknown, the size of effusion, inflammatory signs and the presence of cardiac tamponade may help suggest etiology.

    The objective of this study was to prospectively determine the incidence of venous thrombosis (VT) in the upper limbs in patients with peripherally inserted central catheters (PICC). We prospectively investigated the incidence of VT in the upper limbs of 26 patients who had PICC inserted. The inclusion criteria were all patients who had a PICC inserted, whilst the exclusion criterion was the inability to perform a venogram (allergies, previous contrast medium reaction and inability of gaining venous access). Both valved and non-valved catheters were evaluated. Prior to removal of the PICC, an upper limb venogram was performed. The number of segments involved with VT were determined. The duration of central venous catheterization was classified as; less than 6 days, between 6 days and 14 days and more than 14 days. VT was confirmed in 38.5% (10/26) of the patients. The majority 85.7% (12/14) were complete occlusive thrombi and the majority of VT only involved one segment. There was no statistical correlation between the site of insertion of the PICC and the location of VT. Neither was there any observed correlation between the occurrence of VT with the patient's history of hypertension, hypercholesterolaemia, coronary artery disease, diabetes mellitus, cardiac insufficiency, smoking or cancer. There was also no statistical correlation with the size of the catheter. In conclusion, PICCs are associated with a significant risk of upper extremity deep vein thrombosis (UEVT).

    Full Text Available Hydrochlorothiazide has never been reported as a reason for myopericarditis. An African American female, with past history of hypertension, coronary artery disease, and sulfa allergy, presented with indolent onset and retrosternal chest pain which was positional, pleuritic, and unresponsive to sublingual nitroglycerin. Her medications included hydrochlorothiazide (HCTZ which was started three months ago for uncontrolled hypertension. Significant laboratory parameters included erythrocyte sedimentation rate (ESR of 47 mm/hr and peak troponin of 0.26 ng/mL. Transthoracic echocardiogram (TTE revealed preserved ejection fraction with no segmental wall motion abnormalities; however, it showed moderate pericardial effusion without tamponade physiology. We hypothesize that this myopericarditis could be due to HCTZ allergic reaction after all other common etiologies have been ruled out. There is a scarcity of the literature regarding HCTZ as an etiology for pericardial disease, with only one case reported as presumed hydrochlorothiazide-induced pericardial effusion. Management involves discontinuation of HCTZ and starting anti-inflammatory therapy.

Objective: To determine whether the risk of central line-associated bloodstream infections (CLA-BSIs and sepsis remained constant over the duration of umbilical vein catheters (UVCs in high-risk premature neonates. Methods:retrospective analysis. The data were collected from the medical record of high risk premature neonates who had a UVC placed in neonatal care unit of Husada Utama Hospital between April 1st 2008 to April 30th 2011 with purposive sampling. Catheter duration was observed before and after 14 days on placement. Blood and UVC culture was performed to establish the risk of CLA-BSIs and sepsis. Chi-square and logistic regression analysis were performed in the laboratorium data. Result: A total 44 high risk premature babies with UVCs were enrolled (sepsis group: n = 23 and non sepsis group: n = 21. Baseline demographics were similar between the groups. 15 babies in sepsis group have UVCs duration > 14 days, and 8 babies have UVCs 14 days show blood culture performance in 11 babies with positive evidence, UVCs culture performance is negative in 18 babies (p = 0.456. Burkholderia cepacia and Klebsiella pneumonia mostly appeared in blood culture performance. 25% of UVC culture performance shows Pseudomonas aeroginosa. Conclusions: The catheter duration have no significant difference in risk of sepsis in premature babies with Umbilical Vein Catheters.

    During the 2013-2016 West Africa Ebola virus disease (EVD) epidemic, some EVD patients, mostly health care workers, were evacuated to Europe and the USA. In May 2015, a 37-year old male nurse contracted Ebola virus disease in Sierra Leone. After Ebola virus detection in plasma, he was medically-evacuated to Italy. At admission, rhabdomyolysis was clinically and laboratory-diagnosed and was treated with aggressive hydration, oral favipiravir and intravenous investigational monoclonal antibodies against Ebola virus. The recovery clinical phase was complicated by a febrile thrombocytopenic syndrome with pericardial effusion treated with corticosteroids for 10 days and indomethacin for 2 months. No evidence of recurrence is reported. A febrile thrombocytopenic syndrome with pericardial effusion during the recovery phase of EVD appears to be uncommon. Clinical improvement with corticosteroid treatment suggests that an immune-mediated mechanism contributed to the pericardial effusion.

Catheter unroofing technique has been described as an alternative to peritoneal catheter removal. Material and methods: We analyzed the data from 13 patients retrospectively. Evolution after unroofing was evaluated, considering as treatment failure the appearance of new infection in the hole, tunnel or peritonitis associated to the same germ. Results: Between 1997-2014 years, unroofing was performed on 13 patients. Mean age-rate: 46.2 (IC 95%: 35.9 years – 56.5 years male sex 9, 69.23%. Germs: staphylococcus 7, pseudomona 2, polymicrobial 1, negative culture 3. Nine patiens healed: 69.2%; there was no statistical association among sex, age, microbiological result, previous hemodialysis use, type of catheter, surgical technique or with the surgeon who performed the procedure (p≥ 0.05. Discussion: Catheter removal implies transient transference to hemodialysis and new replacement surgery, although there is few experience with this technique, it could be an acceptable alternative, enabling a group of patients to continue with PD treatment. Conclusion: Unroofing technique proved to be beneficial in 69.2% of the cases (9 patients independently of the type of germ present, representing an acceptable treatment which avoids catheter removal, enabling the procedure to continue, and decreasing the need to employ more aggressive therapies.

    OBJECTIVE The impact of healthcare system integration on infection prevention programs is unknown. Using catheter-associated urinary tract infection (CAUTI) prevention as an example, we hypothesize that U.S. Department of Veterans Affairs (VA) nursing homes have a more robust infection prevention infrastructure due to integration and centralization compared with non-VA nursing homes. SETTING VA and non-VA nursing homes participating in the “AHRQ Safety Program for Long-term Care” collaborative. METHODS Nursing homes provided baseline information about their infection prevention programs to assess strengths and gaps related to CAUTI prevention. RESULTS A total of 353 (71%; 47 VA, 306 non-VA) of 494 nursing homes from 41 states responded. VA nursing homes reported more hours/week devoted to infection prevention-related activities (31 vs. 12 hours, P<.001), and were more likely to have committees that reviewed healthcare-associated infections. Compared with non-VA facilities, a higher percentage of VA nursing homes reported tracking CAUTI rates (94% vs. 66%, P<.001), sharing CAUTI data with leadership (94% vs. 70%, P=.014) and nursing personnel (85% vs. 56%, P=.003). However, fewer VA nursing homes reported having policies for appropriate catheter use (64% vs. 81%, P=.004) and catheter insertion (83% vs. 94%, P=.004). CONCLUSIONS Among nursing homes participating in an AHRQ-funded collaborative, VA and non-VA nursing homes differed in their approach to CAUTI prevention. Best practices from both settings should be applied universally to create an optimal infection prevention program within emerging integrated healthcare systems. PMID:27917728

One hundred and four women with term gestation, with Bishop score < 4, and with various indications for labour induction were randomly divided into two groups. In Group I, 25 μg of misoprostol tablet was placed intravaginally, 4 hourly up to maximum 6 doses. In Group II, Foley catheter 16F was placed through the internal os of the cervix under aseptic condition and then inflated with 50 cc of sterile saline. Statistical analysis was done using SPSS software. Results. The induction to delivery interval was 14.03 ± 7.61 hours versus 18.40 ± 8.02 hours (p<0.01. The rate of vaginal delivery was 76.7% versus 56.8% in misoprostol and transcervical Foley catheter group, respectively. Uterine hyperstimulation was more common with misoprostol. Neonatal outcome was similar in both the groups. Conclusion. Intravaginal misoprostol is associated with a shorter induction to delivery interval as compared to Foley’s catheter and it increases the rate of vaginal delivery in cases of unripe cervix at term. Transcervical Foley catheter is associated with a lower incidence of uterine hyperstimulation during labour.

    Catheter-associated urinary tract infection (CAUTI) is a major preventable cause of harm for patients in hospital and incurs significant costs for health-care providers such as the UK NHS. Many preventative strategies and measures have been introduced to minimise CAUTI risk, including the use of antimicrobial catheters. However, there is considerable uncertainty regarding their usefulness in terms of reducing symptomatic CAUTI, and whether or not they are cost-effective. Do antimicrobial catheters reduce the rate of symptomatic urinary tract infection (UTI) during short-term hospital use and is their use cost-effective for the UK NHS? A pragmatic multicentre UK randomised controlled trial comparing three catheters as they would be used in the UK NHS: antimicrobial-impregnated (nitrofurazone) and antiseptic-coated (silver alloy) catheters with the standard polytetrafluoroethylene (PTFE)-coated catheters. Economic evaluation used a decision model populated with data from the trial. Sensitivity analysis was used to explore uncertainty. Relevant clinical departments in 24 NHS hospitals throughout the UK. Adults requiring temporary urethral catheterisation for a period of between 1 and 14 days as part of their care, predominantly as a result of elective surgery. Eligible participants were randomised 1 : 1 : 1 to one of three types of urethral catheter in order to make the following pragmatic comparisons: nitrofurazone-impregnated silicone catheter compared with standard PTFE-coated latex catheter; and silver alloy-coated hydrogel latex catheter compared with standard PTFE-coated latex catheter. The primary outcome for clinical effectiveness was the incidence of UTI at any time up to 6 weeks post randomisation. This was defined as any symptom reported during catheterisation, up to 3 days or 1 or 2 weeks post catheter removal or 6 weeks post randomisation combined with a prescription of antibiotics, at any of these times, for presumed symptomatic UTI. The primary economic

    Purpose: To assess the feasibility of a new developed field inhomogeneity catheter for interventional MR imaging in vivo. Materials and methods: Three different prototypes of a field inhomogeneity catheter were investigated in 6 pigs. The catheters were introduced in Seldinger technique via the femoral vessels over a guide wire on an interventional MR system (Philips Gyroscan NT combined with a C-arm fluoroscopy unit [Philips BV 212[). Catheters were placed in veins and arteries. The catheter position was controlled by a fast gradient echo sequence (Turbo Field Echo [TEF[). Results: Catheters were introduced over a guide wire without complications in all cases. Using the field inhomogeneity concept, catheters were easily visualised in the inferior vena cava and the aorta by the fast gradient echo technique on MR in all cases. Although aortic branches were successfully cannulated, the catheters were not displayed by the TFE technique due to the complex and tortuous anatomy. All animals survived the experiments without complications. Conclusion: MR guided visualisation of a field inhomogeneity catheter is a simple concept which can be realised on each MR scanner and may allow intravascular MR guided interventions in future.

    Goede, Matthew R; Coopersmith, Craig M

    2009-04-01

    Catheter-related bloodstream infections (CR-BSIs) are a common, frequently preventable complication of central venous catheterization. CR-BSIs can be prevented by strict attention to insertion and maintenance of central venous catheters and removing unneeded catheters as soon as possible. Antiseptic- or antibiotic-impregnated catheters are also an effective tool to prevent infections. The diagnosis of CR-BSI is made largely based on culture results. CR-BSIs should always be treated with antibiotics, and except in rare circumstances the infected catheter needs to be removed.

    We evaluated the technical success and complication rates associated with the radiological placement of tunneled central venous catheters in pediatric patients. Between May 1, 2005 and March 31, 2008, a total of 46 tunneled central venous catheters were placed in 34 children (M:F = 22:12; mean age, 9.9 years [9 months to 16.8 years]). All procedures were performed under ultrasonographic and fluoroscopic guidance. Follow-up data were obtained through the retrospective review of the medical records. We used the Kaplan-Meier survival method for the evaluation of survival rate of the catheters. All procedures were technically successful. The observed periprocedural complications included hematoma formation in three patients. The mean catheter life was 189.3 days (total, 8710 days; range, 7-810). Catheters were removed due to death (n=9), the end of treatment (n=8), catheter sepsis (n=4), malfunction (n=8), and accidental removal (n=4). The rate of catheter sepsis and malfunction was 0.459 and 0.919 for every 1000 catheter days, respectively. The expected mean catheter life was 479.6 days as per the Kaplan- Meier analysis. The results suggest that the radiologic placement of a tunneled central venous catheter is an effective technique with a high technical success rate and low complication rate

    The central paradigm of effective peritoneal dialysis (PD) is an appropriate standard of PD catheter function. The aim of the project was to develop an effective national PD access audit which would identify an 'appropriate standard' of PD catheter function. The UK Renal Registry collected centre specific information on various PD access outcome measures including catheter functionality and post-insertion complications. The first PD access audit covering England, Northern Ireland and Wales was conducted during April to June 2012 looking at incident dialysis patients in 2011. Forty three data collection spreadsheets were returned from a total of 65 centres describing 917 PD catheter placements. The median age of PD patients was 61 years and 61.5% were male. The proportion of patients initiated on PD in comparison to HD was lower in socially deprived areas. There was a relationship between the timing of nephrology referral and the likelihood of surgical assessment regarding PD catheter placement. Patients with diabetes did not have higher rates of PD catheter failure or of early peritonitis. A comparative PD catheter audit has the potential to provide valuable information on an important patient related outcome measure and lead to an improvement in patient experience. There was wide variation between centres of PD catheter use for late presenting patients. Overall patients were more likely to get a PD catheter if they had been known to the service for more than 1 year. The percutaneous insertion technique was associated with a higher early (less than 2 week) peritonitis rate and more catheter flow problems. Copyright © 2013 S. Karger AG, Basel.

    Right sided tears or rupture are the most common injury to the heart after blunt chest trauma. The majority of these injuries are to the thin walled atrium. Reports of localized right atrial appendage rupture are rare. The classical features of Beck's triad are unreliable in the trauma bay. With the advent of EFAST (Focused assessment with sonography for trauma extended to thorax), Beck's triad should be considered but not used as the primary clinical tool for diagnosis of cardiac tamponade [1]. EFAST aids in rapid diagnosis and definitive care [3]. Our patient was a 17 year old male who presented with hypotension after a rollover motor vehicle accident. He presented with a grossly negative physical exam and positive EFAST for pericardial effusion with tamponade physiology. We performed an emergency pericardiocentesis and expedited transportation for operative exploration. A Right atrial appendage injury was identified and repaired and patient recovered uneventfully. EFAST examination aids in rapid diagnosis of cardiac tamponade in the trauma setting. Pericardiocentesis facilitates temporizing the hemodynamics in preparation for operative exploration.

  6. A Minimally Invasive, Translational Method to Deliver Hydrogels to the Heart Through the Pericardial Space

    2017-10-01

    Full Text Available Biomaterials are a new treatment strategy for cardiovascular diseases but are difficult to deliver to the heart in a safe, precise, and translatable way. We developed a method to deliver hydrogels to the epicardium through the pericardial space. Our device creates a temporary compartment for hydrogel delivery and gelation using anatomic structures. The method minimizes risk to patients from embolization, thrombotic occlusion, and arrhythmia. In pigs there were no clinically relevant acute or subacute adverse effects from pericardial hydrogel delivery, making this a translatable strategy to deliver biomaterials to the heart.

    To obtain a quantitative estimate of the impact on infectious complications of using transparent dressings with intravenous catheters. Meta-analysis of all studies published in the English literature, including abstracts, letters, and reports that examined the primary research question of infection risks associated with transparent compared with gauze dressings for use on central and peripheral venous catheters. Studies were identified by use of the MEDLINE database using the indexing terms occlusive dressings, transparent dressings, and infection and by review of referenced bibliographies. Seven of the 15 studies (47%) of central venous catheters and seven of 12 studies (58%) of peripheral catheters met our inclusion criteria for analysis. All studies used a prospective cohort design, utilized hospitalized patients, and reported at least one of our defined outcomes. Data for each study were abstracted independently by three investigators. At least three studies were used in the analysis of each outcome. Applying a Mantel-Haenszel chi 2 analysis, use of transparent dressings on central venous catheters was significantly associated with an elevated relative risk (RR) of catheter tip infection (RR = 1.78; 95% confidence interval [CI], 1.38 to 2.30). Catheter-related sepsis (RR = 1.69; 95% CI, 0.97 to 2.95) and bacteremia (RR = 1.63; 95% CI, 0.76 to 3.47) were both associated with an elevated RR. Use of transparent dressings on peripheral catheters was associated with an elevated RR of catheter-tip infection (RR = 1.53; 95% CI, 1.18 to 1.99) but not phlebitis (RR = 1.02; 95% CI, 0.86 to 1.20), infiltration (RR = 1.12; 95% CI, 0.92 to 1.37), or skin colonization (RR = 0.99; 95% CI, 0.90 to 1.09). The results demonstrated a significantly increased risk of catheter-tip infection with the use of transparent compared with gauze dressings when used with either central or peripheral catheters. An increased risk of bacteremia and catheter sepsis associated with the use of

    In 2014 the Veterans Health Administration (VHA) of the Department of Veterans Affairs (VA) implemented a Virtual Breakthrough Series (VBTS) collaborative to help VHA facilities prevent hospital-acquired conditions: catheter-associated urinary tract infection (CAUTI) and hospital-acquired pressure ulcers (HAPUs). During the prework phase, participating facilities assembled a multidisciplinary team, assessed their current system for CAUTI or HAPU prevention, and examined baseline data to set improvement aims. The action phase consisted of educational conference calls, coaching, and monthly team reports. Learning was conducted via phone, web-based options, and e-mail. The CAUTI bundle focused on four key principles: (1) avoidance of indwelling urinary catheters, (2) proper insertion technique, (3) proper catheter maintenance, and (4) timely removal of the indwelling catheter. The HAPU bundle focused on assessment and inspection, pressure-relieving surfaces, turning and repositioning, incontinence management, and nutrition/hydration assessment and intervention. For the 18 participating units, the mean aggregated CAUTI rate decreased from 2.37 during the prework phase to 1.06 per 1,000 catheter-days during the action (implementation) phase (p model for implementing a virtual model for improvement.

    To evaluate the clinical outcomes after gas tamponade without vitrectomy for retinal detachment associated with an optic disk pit using optical coherence tomography. Intravitreal gas injection was performed on 8 consecutive patients (mean age, 35.0 years; range, 15-74 years) with unilateral macular detachment associated with an optic disk pit. A 0.3-mL injection of 100% sulfur hexafluoride 6 gas was carried out without an anterior chamber tap. Patients treated with gas injection were instructed to remain facedown for 5 days. Complete retinal reattachment after only gas tamponade was achieved in four out of eight eyes. The mean number of gas injections was 1.8. The mean best-corrected visual acuity before and after the treatment with gas tamponade was approximately 30/100 and 20/20, respectively. The period required for reattachment after final gas treatment was 12 months. There were no incidences of recurrence after complete reattachment by gas tamponade in any of the cases during the 94-month average follow-up period (range, 64-132 months). Gas tamponade appears to be an effective alternative method for macular detachment associated with an optic disk pit, even though the mechanisms of optic disk pit maculopathy are still unknown.

    Diagnostic catheterization of the right side of the heart with semirigid cardiac catheters requires fluoroscopic guidance and substantial skill. Abnormal positions of the heart chambers and of the great vessels associated with cardiac dilatation or with congenital malformation present difficulties even to experienced laboratory cardiologists. These problems have been largely overcome by the introduction of balloon tipped flow directed catheters, which allow for rapid and relatively safe catheterization of the pulmonary artery without fluoroscopy. It was through the application of these catheters in the intensive care unit that the many pitfalls in the clinical assessment of hemodynamic disturbances became apparent. Although S3 gallop sounds may be useful in the clinical recognition of chronic ventricular failure, their presence or absence has limited predictive value in estimating left ventricular filling pressure in myocardial infarction. Information derived from right heart catheterization is often pivotal in the evaluation of hemodynamic disorders, in directing treatment, and in monitoring the results of therapy in critically ill patients

    A new dedicated cardiac ventriculography catheter was specifically designed for radial and upper arm arterial access approach. Two catheter configurations have been developed to facilitate retrograde crossing of the aortic valve and to conform to various subclavian, ascending aortic and left ventricular anatomies. The “short” dedicated radial ventriculography catheter is suited for horizontal ascending aortas, obese body habitus, short stature and small ventricular cavities. The “long” dedicated radial ventriculography catheter is suited for vertical ascending aortas, thin body habitus, tall stature and larger ventricular cavities. This new design allows for improved performance, faster and simpler insertion in the left ventricle which can reduce procedure time, radiation exposure and propensity for radial artery spasm due to excessive catheter manipulation. Two different catheter configurations allow for optimal catheter selection in a broad range of patient anatomies. The catheter is exceptionally stable during contrast power injection and provides equivalent cavity opacification to traditional femoral ventriculography catheter designs.

    Every day, people around the world rely on intermittent and indwelling urinary catheters to manage bladder dysfunction, but the potential or actual harm caused by these devices is well-recognised. Current catheter designs can cause urinary tract infection and septicaemia, bladder and urethral trauma and indwelling devices frequently become blocked. Furthermore, the devices can severely disrupt users' lives, limiting their daily activities and can be costly to manage for healthcare providers. Despite this, little significant design innovation has taken place in the last 80 years. In this article current catheter designs and their limitations are reviewed, common catheter-associated problems are outlined and areas of design ripe for improvement proposed. The potential to relieve the individual and economic burden of catheter use is high.

    Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

    The use of long-term catheterisation to manage insensate bladders, often associated with spinal cord injury (SCI), increases the risk of microbial colonisation and infection of the urinary tract. Urinary tract infection (UTI) is typically diagnosed and treated based on the culturing of organisms from the urine, although this approach overlooks low titer, slow growing and non-traditional pathogens. Here, we present an investigation of the urinary tract microbiome in catheterised SCI individuals, using T-RFLP and metagenomic sequencing of the microbial community. We monitored three neurogenic patients over a period of 12 months, who were part of a larger study investigating the efficacy of probiotics in controlling UTIs, to determine how their urinary tract microbial community composition changed over time and in relation to probiotic treatment regimens. Bacterial biofilms adherent to urinary catheters were examined as a proxy for bladder microbes. The microbial community composition of the urinary tract differed significantly between individuals. Probiotic therapy resulted in a significant change in the microbial community associated with the catheters. The community also changed as a consequence of UTI and this shift in community composition preceded the clinical diagnosis of infection. Changes in the microbiota due to probiotic treatment or infection were transient, resolving to microbial communities similar to their pre-treatment communities, suggesting that the native community was highly resilient. Based on these results, we propose that monitoring a patient's microbial community can be used to track the health of chronically catheterized patients and thus, can be used as part of a health-status monitoring program.

  18. An epidural catheter removal after recent percutaneous coronary intervention and coronary artery stenting: Epidural catheter and antiaggregation therapy

    2016-01-01

    Full Text Available Introduction: Anticoagulation and antiplatelet therapy in the presence of the epidural catheter is still controversial. It is well known that dual antiplatelet therapy is indicated for 12 months after the placement of drug-eluting stents (DES. Removal of an epidural catheter during that period is related to an increased risk of stent occlusion in case of discontinuation of platelet function inhibitors or, on the other hand, increased risk of epidural hematoma associated with neurological deficit if suppressed platelet function is still present. Case Report: Here we present a case of a 63-year-old man who was admitted to Institute for Cardiovascular Diseases Dedinje for elective aortic surgery. Before the induction, an epidural catheter was inserted at the Th10-Th11 epidural space. Uneventful surgery was performed under the combined epidural and general anesthesia. On the 2nd postoperative day, the patient sustained a ST depression myocardial infarction treated with percutaneous coronary intervention with DES placement, while epidural catheter was still in place. Dual antiplatelet therapy with 600mg of clopidogrel, 100 mg of acetilsalicylic acid (ASA and low molecular weight heparin (LMWH were started during the procedure. The next day, clopidogrel (75 mg and ASA (100 mg were continued as well as LMWH. The decision to remove the epidural catheter was made on the 9th postoperative day, after platelet aggregation assays were performed. Six hours after catheter removal the patient again received clopidogrel, ASA and LMWH. There were no signs of epidural hematoma. Conclusion: This case shows that point-of-care testing with platelet aggregation assays may be useful in increasing the margin of safety for epidural catheter removal during dual antiplatelet therapy.

    The preferential citation of studies with the highest success rates could exaggerate perceived effectiveness, particularly for treatments with widely varying published success rates such as radiofrequency catheter ablation for atrial fibrillation. We systematically identified observational studies and clinical trials of radiofrequency catheter ablation of atrial fibrillation between 1990 and 2012. Generalized Poisson regression was used to estimate association between study success rate and total citation count, adjusting for sample size, journal impact factor, time since publication, study design, and whether first or last author was a consensus-defined pre-eminent expert. We identified 174 articles meeting our inclusion criteria (36 289 subjects). After adjustment only for time since publication, a 10-point increase above the mean in pooled reported success rates was associated with a 17.8% increase in citation count at 5 years postpublication (95% confidence interval, 7.1-28.4%; Pcitation count; 95% confidence interval, 7.6-29.6%; Pcitation count, which may indicate citation bias. To readers of the literature, radiofrequency catheter ablation of atrial fibrillation could be perceived to be more effective than the data supports. These findings may have implications for a wide variety of novel cardiovascular therapies. © 2014 American Heart Association, Inc.

    Full Text Available Background. Catheter-related infections, thrombosis, and stenosis are among the most frequent complications associated with catheters, which are inserted in vessels. Surface treatment processes of the outer surface, such as ion-beam-assisted deposition, can be used to mitigate such complications. Methods. This retrospective study (1992–2007 evaluated silver-coated (54 patients and noncoated (105 patients implanted large-bore catheters used for extracorporeal detoxification. The catheters were inserted into the internal jugular or subclavian veins. After removal, the catheters were cultured for bacterial colonization using standard microbiologic assays. They also were examined using scanning electron microscope. Results. The silver coated catheters showed a tendency towards longer in situ time. The microbiologic examinations of the catheter tips were in both catheter types high positive, but not significant. Conclusion. The silver-coated catheters showed no significantly reduction in infection rate by evaluation of all collected data in this retrospective study. There was no association between both catheters in significantly reducing savings in treatment costs and in reducing patient discomfort. Other new developed catheter materials such as the microdomain-structured inner and outer surface are considered more biocompatible because they mimic the structure of natural biological surface.

    Care for patients with indwelling urinary catheter is one of the most important factors in preventing problems associated with indwelling urinary catheters. Caregiver education about caring of indwelling urinary catheters is important the same as patient education to prevent urinary catheters problems. A pre test post test control group design was used with nursing students of Zarqa University College. Data were collected through self-administered questionnaire. Experimental group did not do better in the posttest than the control group after they joined an educational session about caring for patients with indwelling urinary catheter. Level of student (first year vs. second year) has been identified as a covariate that may have distorted the results. One educational session is insufficient to change level of knowledge regarding caring for patients with indwelling urinary catheter, in addition to considering the level of nursing student when conducting the educational session.

    Intravenous ports are widely used for oncology patients. However, catheter fractures may lead to the need for re-intervention. We aimed to identify the risk factors associated with catheter fractures. Between January 1 and December 31, 2006, we retrospectively reviewed the clinical data and plain chest films of 1,505 patients implanted with an intravenous port at Chang Gung Memorial Hospital. Different vascular sites were compared using the chi-square or Fisher's exact test for categorical variables, and the t test was used for continuous variables with normal distribution; P port type Arrow French (Fr.) 8.1 (P port and catheter removal is recommended. Female gender, intravenous port implantation via the subclavian route, and the Arrow Fr. 8.1 port were found to be risk factors. Patients with these risk factors should be monitored closely to avoid catheter fractures.

    To discuss the controversies surrounding the indications for catheter angiography versus non-catheter and less invasive angiography techniques (e.g. magnetic resonance angiography (MRA) and computerized tomography angiography (CTA)) in the evaluation of patients with a third nerve palsy. Clinical opinion-perspective and literature review. The patient with an isolated third nerve palsy might have a vasculopathic (and typically benign, self limited course) etiology or a life threatening intracranial posterior communicating artery aneurysm. Although it is clear that non-isolated third nerve palsies require imaging directed at the topographical localization of the clinical findings, the evaluation of the neurologically isolated third nerve palsy remains controversial. The completeness of the external (i.e. somatic) motor dysfunction and the presence or absence of internal (i.e. pupillary) dysfunction are generally used to guide the choice of initial neuroimaging. Advances in MRA and CTA technology have reduced but not eliminated our dependence upon catheter angiography in this setting. A properly performed and interpreted MRA or CTA probably will be able to detect greater than 95 % of aneurysms producing a third nerve palsy. The issues surrounding the use of catheter angiography in third nerve palsy are reviewed. If the clinician is highly confident in the capability, availability, and reliability of the neuroradiologist and of their institutional experience and quality of less invasive non-catheter MRA and CTA and if the risk of aneurysm is low or if the risk of angiography is high (e.g. elderly, renal failure, iodinated contrast allergy, risk of stroke) then MRI and MRA (or CTA) may be a reasonable alternative to catheter angiography. Patients with a moderate or uncertain risk of aneurysm and a lower risk for catheter angiography or if there is a low confidence in the quality or the interpretation of the institutional MRA (or CTA) may still require catheter

    thrombocythemia (ET has never been reported in the literature. We report a case of a 72-year-old Caucasian female who presented with spontaneous hemopericardium and tamponade requiring emergent pericardiocentesis. The patient was subsequently diagnosed to have ET. ET is characterized by elevated platelet counts that can lead to thrombosis but paradoxically it can also lead to a bleeding diathesis. Physicians should be aware of this complication so that timely life-saving measures can be taken if this complication arises.

    Full Text Available This meta-analysis compared the efficacy and safety of the contact force (CF-sensing catheter and second-generation cryoballoon (CB ablation for treating atrial fibrillation (AF. Six controlled clinical trials comparing ablation for AF using a CF-sensing catheter or second-generation CB were identified from PubMed, EMBASE, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure. The procedure duration was significantly lower in the CB group compared with that in the CF group [mean difference (MD=29.4; 95%CI=17.84–40.96; P=0.01], whereas there was no difference between the groups for fluoroscopy duration (MD=0.59; 95%CI=–4.48–5.66; P=0.82. Moreover, there was no difference in the incidence of non-lethal complications (embolic event, tamponade, femoral/subclavian hematoma, arteriovenous fistula, pulmonary vein stenosis, phrenic nerve palsy, and esophageal injury between the CB and the CF groups (8.38 vs 5.35%; RR=0.66; 95%CI=0.37–1.17; P=0.15. Transient phrenic nerve palsy occurred in 17 of 326 patients (5.2% of the CB group vs none in the CF group (RR=0.12; 95%CI=0.03–0.43; P=0.001. A comparable proportion of patients in CF and CB groups suffered from AF recurrence during the 12-month follow-up after a single ablation procedure [risk ratio (RR=1.03; 95%CI=0.78–1.35; P=0.84]. AF ablation using CF-sensing catheters and second-generation CB showed comparable fluoroscopy duration and efficacy (during a 12-month follow-up, with shorter procedure duration and different complications in the CB group.

    Catheter care is considered to be important for prevention of catheter-associated bloodstream infections (CABSIs) although epidemiological evidence is sparse. To identify problems associated with catheter care and evaluate the effectiveness of nurse-initiated interventions to reduce CABSIs. An intervention study with before and after comparison. CABSI surveillance was conducted in a 560-bed acute hospital located in a major urban area in Japan. Patients were enrolled in this study from April 2000 to December 2002 based on the following criteria: (1) adult inpatients; and (2) those in whom central venous lines or Swan-Ganz catheters were inserted for 2 days or longer. In the first year, risk factors for CABSI and problems associated with catheter care were identified by inspection of the infection control nurse (ICN) or four trained link nurses, and the laboratory results. In the subsequent 2 years, the following interventions based on the surveillance results were implemented: (1) enhanced skin preparation by scrubbing with regular bathing soap and tap water; (2) a new method for stabilisation of the catheter inserted into the internal jugular vein, where additional dressing was placed over the sterilised dressing; (3) educating the staff on maximal sterile precautions by teaching staff members at their section meetings and displaying posters; (4) use of a check list and observation of catheter insertion by link nurses to monitor compliance; and (5) selection of a disinfectant that requires shorter contact time and has longer residual effect. After these interventions were implemented, the overall bloodstream infection (BSI) rate declined from 4.0/1000 device-days to 1.1/1000 device-days (p<0.005). We identified four problems-those related to skin preparation, dressing, sterile precautions and disinfectant. We implemented a series of interventions to reduce CABSIs; the overall CABSI rate decreased significantly.

    The Commission for Hospital Hygiene and Infection Prevention (KRINKO) updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt's hospitals in autumn, 2015. In two non-ICU wards of each of Frankfurt's 17 hospitals, inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of 5 wards were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters) and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model. Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%). In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change. Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two nurses. Against this background, a sufficient

    Objective: To determine the incidence of pericatheter sleeve formation, thrombus formation, and stenosis of the central veins in hemodialysis patients with temporary catheters. Methods and material: In this prospective study, 57 patients (40 males, 17 females) with temporary dialysis catheters had catheter venography by pulling back the catheter just before removal. Patient's age range was 25-87 years (mean age, 51 years). The venographic studies were evaluated for pericatheter sleeve formation, thrombus formation, and stenosis of the brachiocephalic vein (BCV) and the superior vena cava (SVC). The IJV could only be evaluated if there was adequate filling during contrast administration. In a subgroup of patients who had had only right IJV or only right SCV catheters, impact of these catheters on the central veins was compared. Results: The catheter location was right internal jugular vein (IJV) in 26 cases, right subclavian vein (SCV) in 27 cases, left IJV in 1 case, and left SCV in 3 cases. Thirty-two patients (56%) had had only one temporary catheter and the rest had had more than one inserted. The mean dwell time for the catheters was 21 days (range 7-59 days). A pericatheter sleeve was detected on venography in 32 (56%) patients and thrombus formation was noted in 16 patients (28%). A total of 41 patients (72%) exhibited pericatheter sleeve and/or thrombus formation. While 19 of the 32 patients (59%) without previous catheterization had a sleeve around the catheter, only 13 (52%) of 25 patients who had had multiple catheters inserted had a sleeve (P>0.05). Of the eight patients (14%) with BCV stenosis, two had >50% stenosis. Only one patient (2%) had mild stenosis of the SVC. Three patients out of 15 (20%) who had diagnostic venography for the IJV had severe stenosis of the vein. Pericatheter sleeve formation was more frequent in women (P<0.05). However, there were no statistical differences with respect to pericatheter sleeve formation, luminal filling

    Full Text Available The purpose of this study was to report our experience of percutaneous retrieval of dislodged port catheters with concurrent use of pigtail and loop snare catheters. During a 5-year period at our institute (June 2005 to July 2010, a total of 23 dislodged port catheters were retrieved. The interval between port catheter implantation and dislodged catheter retrieval ranged from 43 days to 1,414 days (mean 586.7 days. The time of delayed retrieval ranged from 1 day to 45 days (mean 4.6 days. All dislodged catheters were retrieved with the concurrent use of pigtail and loop snare catheters via femoral venous route. The prevalence of port catheter dislodgement at our institute was 3.4%. All dislodged port catheters were removed successfully with pigtail and loop snare catheters together. No procedure-related complications were encountered, except for transient arrhythmia in two patients, which required no medication. In conclusion, the concurrent use of pigtail and loop snare catheters is a feasible and easy way for percutaneous retrieval of a dislodged central venous port catheter.

    2018-06-01

    Full Text Available Urinary tract infections (UTI are the most common hospital-acquired infections in humans and are caused primarily by uropathogenic Escherichia coli (UPEC. Indwelling urinary catheters become encrusted with UPEC biofilms that are resistant to common antibiotics, resulting in chronic infections. Therefore, it is important to control UPEC biofilms on catheters to reduce the risk for UTIs. This study investigated the efficacy of selenium for inhibiting and inactivating UPEC biofilms on urinary catheters. Urinary catheters were inoculated with UPEC and treated with 0 and 35 mM selenium at 37 °C for 5 days for the biofilm inhibition assay. In addition, catheters with preformed UPEC biofilms were treated with 0, 45, 60, and 85 mM selenium and incubated at 37 °C. Biofilm-associated UPEC counts on catheters were enumerated on days 0, 1, 3, and 5 of incubation. Additionally, the effect of selenium on exopolysacchride (EPS production and expression of UPEC biofilm-associated genes was evaluated. Selenium at 35 mM concentration was effective in preventing UPEC biofilm formation on catheters compared to controls (p < 0.05. Further, this inhibitory effect was associated with a reduction in EPS production and UPEC gene expression. Moreover, at higher concentrations, selenium was effective in inactivating preformed UPEC biofilms on catheters as early as day 3 of incubation. Results suggest that selenium could be potentially used in the control of UPEC biofilms on urinary catheters.

    Central line-associated bloodstream infection (CLABSI, hereafter referred to in this paper as "bloodstream infection") is a leading cause of hospital-acquired infection. To our knowledge, there are no previously published studies designed to determine the rate of bloodstream infection among central venous catheters placed in the emergency department (ED). We design a retrospective chart review methodology to determine bloodstream infection and duration of catheterization for central venous catheters placed in the ED. Using hospital infection control, administrative, and ED billing databases, we identified patients with central venous catheters placed in the ED between January 1, 2007, and December 31, 2008, at one academic, urban ED with an annual census of 57,000. We performed a structured, explicit chart review to determine duration of catheterization and confirm bloodstream infection. We screened 4,251 charts and identified 656 patients with central venous catheters inserted in the ED, 3,622 catheter-days, and 7 bloodstream infections. The rate of bloodstream infection associated with central venous catheters placed in the ED was 1.93 per 1,000 catheter-days (95% confidence interval 0.50 to 3.36). The mean duration of catheterization was 5.5 days (median 4; range 1 to 29 days). Among infected central venous catheters, the mean duration of catheterization was 8.6 days (median 7; range 2 to 19 days). A total of 667 central venous catheters were placed in the internal jugular (392; 59%), subclavian (145; 22%), and femoral (130; 19%) veins. The sensitivity of using ED procedural billing code for identifying ED-placed central venous catheters among patients subsequently admitted to any ICU was 74.9% (95% confidence interval 71.4% to 78.3%). The rate of ED bloodstream infection at our institution is similar to current rates in ICUs. Central venous catheters placed in the ED remain in admitted patients for a substantial period.

    Atrial fibrillation (AF) is associated with inflammation. Increased serum C-reactive protein (CRP) levels are important representatives of an inflammatory state of AF. A variety of studies have evaluated whether increased CRP levels have an association with AF recurrence after catheter ablation. However, the results remain inconsistent, therefore, this meta-analysis was conducted to offer suggestions. Increased baseline CRP have an association with AF recurrence after catheter ablation. Electronic databases including PubMed, Embase, Medline, ISI Web of Knowledge, and ScienceDirect were searched until December 31, 2012 for any CRP-associated studies. Overall and subgroup analyses were performed. Standardized mean difference (SMD) and 95% confidence interval (CI) were used to evaluate the associations between CRP levels and postablation AF recurrence. Statistical analysis was performed with Review Manager 5.2 and Stata 11.0. Seven available studies were identified, which included 526 patients (179 recurrence vs 347 no recurrence). Overall, increased baseline CRP levels had significant positive association with postablation AF recurrence. The SMD in the CRP levels was 0.65 units (95% CI: 0.30-0.99), and the z-score for overall effect was 3.70 (P = 0.0002). The heterogeneity test showed that there were moderate differences between individual studies (P = 0.006, I(2) = 67%). Metaregression revealed that different sample sizes of studies possibly accounted for the heterogeneity. Positive associations were also found in subgroup analyses based on sample size. When stratifying for ethnicity, similarly significant associations were found in both European (Caucasian) and Asian populations. Investigations demonstrate that baseline CRP levels are greater in patients with postablation AF recurrence. Further studies with larger sample size and delicate design for CRP should be conducted. © 2013 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Indwelling urinary catheters are the main cause of healthcare-associated urinary tract infections. It can be expected that reduction of the use of urinary catheters will lead to decreased numbers of urinary tract infection. Methods The efficacy of an intervention programme to improve adherence to recommendations to reduce the use of urethral catheters was studied in a before-after comparison in ten Dutch hospitals. The programme detected barriers and facilitators and each individual facility was supported with developing their own intervention strategy. Outcome was evaluated by the prevalence of catheters, alternatives such as diapers, numbers of urinary tract infections, the percentage of correct indications and the duration of catheterization. The costs of the implementation as well as the catheterization were evaluated. Results Of a population of 16,495 hospitalized patients 3335 patients of whom 2943 were evaluable for the study, had a urethral catheter. The prevalence of urethral catheters decreased insignificantly in neurology (OR 0.93; 95% CI 0.77 - 1.13 and internal medicine wards (OR 0.97; 95% CI 0.83 - 1.13, decreased significantly in surgical wards (OR 0.84; 95% CI 0.75 - 0.96, but increased significantly in intensive care (IC and coronary care (CC units (OR 1.48; 95% CI 1.01 - 2.17.

    Catheter-associated urinary tract infections (CAUTI) account for approximately 25% of nosocomial infections globally, and often result in increased morbidity and healthcare costs. An additional concern is the presence of microbial biofilms which are major reservoirs of bacteria, especially antibiotic-resistant bacteria, in catheters. Since introduction of the use of closed drainage systems, innovations to combat CAUTI have not led to significant improvements in clinical outcomes. The lack of a robust laboratory platform to test new CAUTI preventive strategies may impede development of novel technologies. To establish an in-vitro catheterization model (IVCM) for testing of technological innovations to prevent CAUTI. The IVCM consists of a continuous supply of urine medium flowing into a receptacle (bladder) where the urine is drained through a urinary catheter connected to an effluent collection vessel (drainage bag). Test organism(s) can be introduced conveniently into the bladder via a rubber septa port. Development of bacteriuria and microbial biofilm on the catheter can be determined subsequently. With an initial inoculum of Escherichia coli [∼5×10 5  colony-forming units (cfu)/mL] into the bladder, a 100% silicone catheter and a commercially available silver-hydrogel catheter showed heavy biofilm colonization (∼10 8  cfu/cm and ∼10 7  cfu/cm, respectively) with similar bacterial populations in the urine (bacteriuria) (∼10 8  cfu/mL and ∼10 7  cfu/mL, respectively) within three days. Interestingly, an antimicrobial peptide (CP11-6A)-coated catheter showed negligible biofilm colonization and no detectable bacteriuria. The IVCM is a useful preclinical approach to evaluate new strategies for the prevention of CAUTI. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model.Results: Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%. In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change.Conclusion: Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two

    Full Text Available Transradial coronary angiography (TRC can be performed with a one-catheter approach for the right and left coronary ostium (R/LCO. We investigated the performance of a special diagnostic catheter widely used for the one-catheter-approach, the Tiger (Tiger II, TerumoTM.In a dual center registry we analyzed 1412 TRC-procedures exclusively performed by experienced TRC-operators. We compared the performance of the Tiger with Judkins catheters by retrospectively judging ostial catheter stability during contrast injection, and by measuring contrast use, fluoroscopy time (FT and complication rate.Poor or failed ostial engagement was found in 40.5% in the Tiger group, compared to 46.6% with the use of Judkins catheters (p<0.183. Ostial instability of the Tiger was found more often during engagement of the LCO than the RCO (34.4% vs. 10.8%, p<0.001, whereas it was similar in the LCO and RCO for Judkins catheters (27.4% vs. 26.7%, p = 0.840. TRC-procedures performed with Tiger catheters were associated with less contrast volume (63.48 ± 29.83mL vs. 82.51 ± 56.58mL, p<0.004 and shorter FT than with Judkins catheters. (198.27 ± 194.8sec vs. 326.85 ± 329.70sec. Forearm hematomas occurred less often with the Tiger (1.2% vs. 6.6%, p< 0.02.The Tiger employed as a single catheter in TRC is an effective tool to achieve lower contrast volume and fluoroscopy time at a low complication rate. Unstable engagement affects predominantly the left coronary artery, but its overall frequency is similar for both, the Tiger and Judkins catheters.

    A 5-year-old castrated mongrel dog was brought to our hospital with anorexia and vomiting. Laboratory testing revealed immune-mediated hemolytic anemia (IMHA), and so treatment was initiated with multiple immune-suppressing drugs, achieving partial remission from IMHA. However, cardiac tamponade due to purulent pericarditis was identified as a secondary disease. Culture of pericardial fluid yielded numerous Candida albicans and multidrug-resistant Acinetobacter sp. Pericardiocentesis was performed, and the condition of the dog improved. However, the dog died the next day

    Coronary artery perforation is a highly feared complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and can lead to pericardial effusion, tamponade, and, rarely, emergent cardiac surgery. Perforation of epicardial collaterals during retrograde CTO-PCI may be particularly challenging to treat, as embolization from both sides of the perforation may be required to control the bleeding. However, conservative measures can occasionally be effective. We present a case of epicardial collateral vessel perforation that was managed conservatively with anticoagulation reversal.

    Full Text Available The present prospective study was carried out in the Paediatric Intensive Care Unit (PICU of a tertiary care teaching hospital in Mumbai. The objective was to determine the incidence, risk factors, mortality and organisms responsible for urinary catheter related infections (UCRI. Colonization and/or bacteriuria was labelled as urinary catheter related infection (UCRI. Forty-four patients with 51 urinary catheters were studied. Incidence of UCRI was 47.06%. Age, female sex and immunocompromised status did not increase the risk of UCRI. Duration of catheter in-situ and duration of stay in the PICU were associated with higher risk of UCRI. The mortality was not increased by UCRI. Commonest organism isolated in UCRI was E. coli, which had maximum susceptibility to nitrofurantoin and amikacin.

    Central line-associated bloodstream infections (CLABSIs) are not easily treated, and many catheters (e.g., hemodialysis catheters) are not easily replaced. Biofilms (the source of infection) on catheter surfaces are notoriously difficult to eradicate. We have recently demonstrated that modest elevations of temperature lead to increased staphylococcal susceptibility to vancomycin and significantly soften the biofilm matrix. In this study, using a combination of microbiological, computational, and experimental studies, we demonstrate the efficacy, feasibility, and safety of using heat as an adjuvant treatment for infected hemodialysis catheters. Specifically, we show that treating with heat in the presence of antibiotics led to additive killing of Staphylococcus epidermidis with similar trends seen for Staphylococcus aureus and Klebsiella pneumoniae. The magnitude of temperature elevation required is relatively modest (45-50°C) and similar to that used as an adjuvant to traditional cancer therapy. Using a custom-designed benchtop model of a hemodialysis catheter, positioned with tip in the human vena cava as well as computational fluid dynamic simulations, we demonstrate that these temperature elevations are likely achievable in situ with minimal increased in overall blood temperature.

    Full Text Available We report a case of a patient who experienced a catheter-related bloodstream infection caused by Staphylococcus condimenti, which was first isolated from soy sauce mash. This is the first reported case of human infection. Although blood culture isolates and the catheter tip tube did not reveal coagulase or clumping factor, false-positive results were obtained from latex agglutination tests for clumping factor and protein A due to self-agglutination. Care is needed when performing only latex agglutination test without a coagulase test. Further studies are needed to determine the pathogenic potential of S. condimenti based on appropriate identification.

    Catheter malfunction is the main reason for early peritoneal dialysis (PD) technique failure. This study aimed to evaluate the effect of a new surgery technique with catheter fixation to the lower abdominal wall combined with straight upward tunnel and low implant position in reducing catheter malfunction. Patients with end stage renal disease who received PD in our centre from January 2013 to December 2015 were involved in this study. They were randomly divided into three groups according to surgical technique: traditional open surgery group, modified open surgery group and modified open surgery with catheter fixation group. All patients were followed up for six months after surgery. Catheter- related complications were analyzed. A total of 152 patients were involved. Among them, 49 received traditional open surgery (TOS group), 49 received modified open surgery (MOS group), and 54 received modified open surgery with catheter fixation (MOS-F group). During follow-up, no patients (0%) in MOS-F group developed catheter malfunction which was significantly lower than that of the TOS group (0 vs 16.33%, P = 0.002). Although not statistically significant, the incidence of catheter malfunction was lower in MOS-F group than that in MOS group (0 vs 4.08%, P = 0.134). No significant difference was observed in the episodes of infection, bleeding, leakage, inflow or outflow pain, hernia and delayed wound healing among the three groups (all P > 0.05). Catheter fixation combined with straight upward tunnel and low implant position can effectively prevent catheter malfunction in PD catheter placement. © 2016 Asian Pacific Society of Nephrology.

  8. Cardiovascular effects of radiation therapy

    2001-01-01

    Therapeutic mediastinal irradiation can induce heart disease with variable degree of cardiac engagement. Heart disease manifestations depend on the grade of involvement of the different cardiac structures. During the first two years following irradiation, pericarditis with or without pericardial effusion is the most common manifestation of toxicity related to radiation therapy. Later on, after a latency period of five to ten years, a constrictive pericarditis may develop. Other type of late cardiac toxicities due to irradiation are restrictive cardiomyopathy, multiple valvular disease, coronary artery disease and different atrioventricular conduction disturbances. The therapeutic approach to this kind of heart disease has to be focused on its progressive course and in the possibility of a global involvement of all the cardiac structures. Pericardiectomy is strongly recommended for recurrent pericardial effusion with cardiac tamponade. Cardiac surgery for myocardial revascularization or valvular disease can be performed with variable results; the presence of myocardial fibrosis can significantly affect perioperative management and long-term results. Cardiac transplantation is a promissory option for those patients with end-stage cardiac failure. Immunosuppressive regimens are not associated with recurrence of malignancy. (author) [es

    Over the past 4 years, 55 cases (one transudate, 28 exudates, and 26 empymas) were drained. Surgical chest tubes alone were used in 35 drainages, percutaneous catheters alone in five drainages, and both types in 15 drainages. Percutaneous catheter drainage was successful in 12 of 20 drainages (60%). Surgical tube drainage was successful in 18 of 50 drainages (36%). The success rate for the nonempyema group was 45% with both types of drainage. For the empyema group, the success rate for percutaneous catheter drainage was 66% vs 23% for surgical tube drainage. Seven major complications occurred with surgical tube drainage, but only one major complication occurred with percutaneous catheter drainage. Radiologically guided percutaneous catheter drainage should be the procedure of choice for pleural fluid drainage. It has a higher success rate for empyemas and is associated with less complications

    A peripherally inserted central catheter (PICC) is a useful option in providing secure venous access, which enables patients to be discharged earlier with the provision of home care. The objective was to identify the costs associated with having a PICC from a societal perspective, and to identify factors that are associated with total PICC costs. Data were obtained from a retrospective cohort of 469 hospitalized pediatric patients with PICCs inserted. Both direct and indirect costs were estimated from a societal perspective. Insertion costs, complication costs, nurse and physician assessment costs, inpatient ward costs, catheter removal costs, home care costs, travel costs, and the cost associated with productivity losses incurred by parents were included in this study. Based on catheter dwell time, the median total cost associated with a PICC per patient per day (including inpatient hospital costs) was $3,133.5 ($2,210.7-$9,627.0) in 2017 Canadian dollars ($1.00USD = $1.25CAD in 2017). The adjusted mean cost per patient per day was $2,648.2 ($2,402.4-$2,920.4). Excluding inpatient ward costs, the median total and adjusted costs per patient per day were $198.8 ($91.8-$2,475.8) and $362.7($341.0-$386.0), respectively. Younger age, occurrence of complications, more catheter dwell days, wards with more intensive care, and the absence of home care were significant factors associated with higher total PICC costs. This study has demonstrated the costs associated with PICCs. This information may be helpful for healthcare providers to understand PICC related cost in children and resource implications.

    Background: Coronary atherosclerosis has traditionally been proposed to be associated with several cardiovascular risk factors and anthropometric measures. However, clinical data regarding the independent value of visceral adipose tissue in addition to such traditional predictors remains obscure. Materials and methods: We subsequently studied 719 subjects (age: 48.1 ± 8.3 years, 25% females) who underwent multidetector computed tomography (MDCT) for coronary calcium score (CCS) quantification. Baseline demographic data and anthropometric measures were taken with simultaneous body fat composition estimated. Visceral adipose tissue of pericardial and thoracic peri-aortic fat was quantified by MDCT using TeraRecon Aquarius workstation (San Mateo, CA). Traditional cardiovascular risk stratification was calculated by metabolic (NCEP ATP III) and Framingham (FRS) scores and high-sensitivity CRP (Hs-CRP) was taken to represent systemic inflammation. The independent value of visceral adipose tissue to systemic inflammation and CCS was assessed by utilizing multivariable regression analysis. Results: Of all subjects enrolled in this study, the mean values for pericardial and peri-aortic adipose tissue were 74.23 ± 27.51 and 7.23 ± 3.69 ml, respectively. Higher visceral fat quartile groups were associated with graded increase of risks for cardiovascular diseases. Both adipose burdens strongly correlated with anthropometric measures including waist circumference, body weight and body mass index (all p < 0.001). In addition, both visceral amount correlates well with ATP and FRS scores, all lipid profiles and systemic inflammation marker in terms of Hs-CRP (all p < 0.001). After adjustment for baseline variables, both visceral fat were independently related to Hs-CRP levels (all p < 0.05), but only pericardial fat exerted independent role in coronary calcium deposit. Conclusion: Both visceral adipose tissues strongly correlated with systemic inflammation beyond traditional

    Full Text Available Abstract Background Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI. Methods Patients undergoing haemodialysis (HD via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions vs thrice per week heparin locks. Results Observed catheter days in the heparin (n=24 and ethanol (n=25 groups were 1814 and 3614 respectively. CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12. Flow issues requiring catheter removal occurred at a rate of 1.6 vs 1.4 per 1000 catheter days in the heparin and ethanol groups respectively (IRR 0.85; 95% CI 0.20-3.5 p =0.82 (for ethanol vs heparin. Conclusions Catheter survival and catheter-related blood stream infection were not significantly different but there was a trend towards a reduced rate of infection in the ethanol group. This study establishes proof of concept and will inform an adequately powered multicentre trial to definitively examine the efficacy and safety of ethanol locks as an alternative to current therapies used in the prevention of catheter-associated blood stream infections in patients dialysing with tunnelled catheters.

    To reduce the incidence of urinary tract infection, Surgical Care Improvement Project 9 mandates the removal of urinary catheters within 48 hours postoperatively. In patients with thoracic epidural anesthesia, we sought to determine the rate of catheter reinsertion, the complications of reinsertion, and the factors associated with reinsertion. We conducted a prospective observational study of consecutive patients undergoing major pulmonary or esophageal resection with thoracic epidural analgesia over a 2-year period. As per Surgical Care Improvement Project 9, all urinary catheters were removed within 48 hours postoperatively. Excluded were patients with chronic indwelling catheter, patients with urostomy, and patients requiring continued strict urine output monitoring. Multivariable logistic regression analysis was used to identify independent risk factors for urinary catheter reinsertion. Thirteen patients met exclusion criteria. Of the 275 patients evaluated, 60 (21.8%) required reinsertion of urinary catheter. There was no difference in the urinary tract infection rate between patients requiring reinsertion (1/60 [1.7%]) versus patients not requiring reinsertion (1/215 [0.5%], P = .389). Urethral trauma during reinsertion was seen in 1 of 60 patients (1.7%). After reinsertion, discharge with urinary catheter was required in 4 of 60 patients (6.7%). Multivariable logistic regression analysis found esophagectomy, lower body mass index, and benign prostatic hypertrophy to be independent risk factors associated with catheter reinsertion after early removal in the presence of thoracic epidural analgesia. When applying Surgical Care Improvement Project 9 to patients undergoing thoracic procedures with thoracic epidural analgesia, consideration to delayed removal of urinary catheter may be warranted in patients with multiple risk factors for reinsertion.

    2012-01-01

    Full Text Available The maintenance of tunneled catheter (TC patency is critical for the provision of adequate hemodialysis in patients who are TC-dependent. TC dysfunction results in the need for costly and inconvenient interventions, and reduced quality of life. Since the introduction of TCs in the late 1980s, heparin catheter lock has been the standard prophylactic regimen for the prevention of TC dysfunction. More recently, alternative catheter locking agents have emerged, and in some cases have shown to be superior to heparin lock with respect to improving TC patency and reducing TC-associated infections. These include citrate, tissue plasminogen activator, and a novel agent containing sodium citrate, methylene blue, methylparaben, and propylparaben. In addition, prophylaxis using oral anticoagulants/antiplatelet agents, including warfarin, aspirin, ticlodipine, as well as the use of modified heparin-coated catheters have also been studied for the prevention of TC dysfunction with variable results. The use of oral anticoagulants and/or antiplatelet agents as primary or secondary prevention of TC dysfunction must be weighed against their potential adverse effects, and should be individualized for each patient.

    Fecal contamination is a major challenge in patients in acute/critical care settings that is associated with increased cost of care and supplies and with development of pressure ulcers, incontinence dermatitis, skin and soft tissue infections, and urinary tract infections. To assess the economic impact of fecal containment in bedridden patients using 2 different indwelling bowel catheters and to compare infection rates between groups. A multicenter, observational study was done at 12 US sites (7 that use catheter A, 5 that use catheter B). Patients were followed from insertion of an indwelling bowel catheter system until the patient left the acute/critical care unit or until 29 days after enrollment, whichever came first. Demographic data, frequency of bedding/dressing changes, incidence of infection, and Braden scores (risk of pressure ulcers) were recorded. The study included 146 bedridden patients (76 with catheter A, 70 with catheter B) who had similar Braden scores at enrollment. The rate of bedding/dressing changes per day differed significantly between groups (1.20 for catheter A vs 1.71 for catheter B; P = .004). According to a formula that accounted for personnel resources and laundry cycle costs, catheter A cost $13.94 less per patient per day to use than did catheter B. Catheter A was less likely than was catheter B to be removed during the observational period (P = .03). Observed infection rates were low. Catheter A may be more cost-effective than catheter B because it requires fewer unscheduled linen changes per patient day.

    To describe the clinical practice of insertion of arterial catheters in anesthetized dogs and cats, to document complications of arterial catheterization, and to determine risk factors associated with the complications. Prospective clinical study and retrospective evaluation of medical records. University teaching hospital. Dogs (n = 251) and 13 cats anesthetized for clinical procedures with arterial catheters inserted for blood pressure monitoring. None. Details of the animal and catheter were collected at the time of anesthesia. On the following day, the catheter site was palpated and observed for abnormalities and the medical records of all animals were reviewed retrospectively for complications. Details of catheter placement were available for 216 catheters: 158 catheters in a dorsal pedal artery, 50 catheters in the median caudal (coccygeal) artery, 6 in the median artery, and 1 each in a cranial tibial and lingual artery. Blood pressure was obtained from 200 catheters, and 12 catheters failed before the end of anesthesia. Postoperative observational data obtained from 112 catheters described a palpable arterial pulse at 73 sites and no pulse at 21 sites. No risk factor for arterial occlusion was identified. No complications resulting from arterial catheterization were noted in the medical records. Arterial catheterization resulted in loss of a peripheral pulse postoperatively in 21/94 (22.3%) of animals examined, although no evidence of tissue ischemia was noted in the medical records of any of the patients in this study. These results suggest that insertion of a catheter in the dorsal pedal or coccygeal arteries was not associated with a high risk for complications. However, the course of arterial occlusion postoperatively warrants further investigation. © Veterinary Emergency and Critical Care Society 2016.

    Purpose: To investigate the use of a system using electromagnetic tracking (EMT), post-processing and an error-detection algorithm for detecting errors and resolving uncertainties in high-dose-rate brachytherapy catheter digitization for treatment planning. Methods: EMT was used to localize 15 catheters inserted into a phantom using a stepwise acquisition technique. Five distinct acquisition experiments were performed. Noise associated with the acquisition was calculated. The dwell location configuration was extracted from the EMT data. A CT scan of the phantom was performed, and five distinct catheter digitization sessions were performed. No a priori registration of the CT scan coordinate system with the EMT coordinate system was performed. CT-based digitization was automatically extracted from the brachytherapy plan DICOM files (CT), and rigid registration was performed between EMT and CT dwell positions. EMT registration error was characterized in terms of the mean and maximum distance between corresponding EMT and CT dwell positions per catheter. An algorithm for error detection and identification was presented. Three types of errors were systematically simulated: swap of two catheter numbers, partial swap of catheter number identification for parts of the catheters (mix), and catheter-tip shift. Error-detection sensitivity (number of simulated scenarios correctly identified as containing an error/number of simulated scenarios containing an error) and specificity (number of scenarios correctly identified as not containing errors/number of correct scenarios) were calculated. Catheter identification sensitivity (number of catheters correctly identified as erroneous across all scenarios/number of erroneous catheters across all scenarios) and specificity (number of catheters correctly identified as correct across all scenarios/number of correct catheters across all scenarios) were calculated. The mean detected and identified shift was calculated. Results: The

Three types of errors were systematically simulated: swap of two catheter numbers, partial swap of catheter number identification for parts of the catheters (mix), and catheter-tip shift. Error-detection sensitivity (number of simulated scenarios correctly identified as containing an error/number of simulated scenarios containing an error) and specificity (number of scenarios correctly identified as not containing errors/number of correct scenarios) were calculated. Catheter identification sensitivity (number of catheters correctly identified as erroneous across all scenarios/number of erroneous catheters across all scenarios) and specificity (number of catheters correctly identified as correct across all scenarios/number of correct catheters across all scenarios) were calculated. The mean detected and identified shift was calculated. Results: The

    We report a case of thymic hyperplasia accompanied by pericardial lipomatosis and right facial hemihypertrophy in an 8-year-old boy. On imaging studies, the hyperplastic thymus had prominent curvilinear and nodular fatty areas simulating a fat-containing anterior mediastinal mass, which is an unusual finding in children. To our knowledge, this is the first report on a child with a combination of thymic hyperplasia, pericardial lipomatosis, and right facial hemihypertrophy. The radiologic findings are presented with a brief discussion.

    Central venous access devices play an important role in patients with prolonged intravenous administration requirements. In the last years, the coating of these devices with bactericidal compounds has emerged as a potential tool to prevent bacterial colonization. Our study describes the modification of 3D-printed reservoirs and silicone-based catheters, mimicking central venous access devices, through different approaches including their coating with the well known biocompatible and bactericidal polymer chitosan, with the anionic polysaccharide alginate; also, plasma treated surfaces were included in the study to promote polymer adhesion. The evaluation of the antimicrobial action of those surface modifications compared to that exerted by a model antibiotic (ciprofloxacin) adsorbed on the surface of the devices was carried out. Surface characterization was developed by different methodologies and the bactericidal effects of the different coatings were assayed in an in vitro model of Staphylococcus aureus infection. Our results showed a significant reduction in the reservoir roughness (≤73%) after coating though no changes were observed for coated catheters which was also confirmed by scanning electron microscopy, pointing to the importance of the surface device topography for the successful attachment of the coating and for the subsequent development of bactericidal effects. Furthermore, the single presence of chitosan on the reservoirs was enough to fully inhibit bacterial growth exerting the same efficiency as that showed by the model antibiotic. Importantly, chitosan coating showed low cytotoxicity against human keratinocytes, human lung adenocarcinoma epithelial cells, and murine colon carcinoma cells displaying viability percentages in the range of the control samples (>95%). Chitosan-based coatings are proposed as an effective and promising solution in the prevention of microbial infections associated to medical devices.

    Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacterial biofilm formation was assessed by quantitative culture and scanning electron microscopy. These data were further correlated to an in vivo rabbit model. We challenged 31 rabbits daily for 4 days by inoculating the urethral meatus with 1.0 × 109 CFU streptomycin-resistant Escherichia coli per day. In vitro, Gendine-coated urinary catheters reduced the CFU of all organisms tested for biofilm adherence compared with uncoated and silver hydrogel-coated catheters (P < 0.004). Scanning electron microscopy analysis showed that a thick biofilm overlaid the control catheter and the silver hydrogel-coated catheters but not the Gendine-coated urinary catheter. Similar results were found with the rabbit model. Bacteriuria was present in 60% of rabbits with uncoated catheters and 71% of those with silver hydrogel-coated catheters (P < 0.01) but not in those with Gendine-coated urinary catheters. No rabbits with Gendine-coated urinary catheters had invasive bladder infections. Histopathologic assessment revealed no differences in toxicity or staining. Gendine-coated urinary catheters were more efficacious in preventing catheter-associated colonization and urinary tract infections than were silver hydrogel-coated Foley catheters and uncoated catheters.

    The objective of this paper is to present aspects of peripherally inserted central catheter and peripheral venous catheter, highlighting important points in choosing the type of access. For the passage of peripherally inserted central catheter is previously performing specific course necessary, while the primary indication occurs when it is necessary to access the patient's stay for a long period of time. Whereas peripheral venipuncture is the most appropriate in cases of needing an IV line quickly and safely, for the administration of fluids, blood collection, blood transfusion and other.

    Difficulty in engaging with guide catheters is not uncommon in acute emergencies. We aimed to evaluate the use of Cordis ® INFINITI diagnostic catheters to perform angioplasty in patients in whom the coronaries cannot be engaged using standard guide catheters. In 34 cases of acute coronary syndrome, when difficulty in engagement with two standard guide catheters was encountered with reasonable manipulations, angioplasty was performed using diagnostic catheters. In total, 40 stents were placed by this technique. Pushability and trackability, distal tip flexion and three-point bending tests were performed to evaluate the performance of the guide and diagnostic catheters. Angioplasty was performed easily in a setting where it would have been very difficult to perform. Coronary dissection occurred in one patient, treated by a stent. The stent and dilatation balloons were easily passed through the diagnostic catheters. Pressure tracings were clearly preserved with certain stent delivery systems, and at angioplasty, although there was slightly reduced opacification of the respective artery, the coronary anatomy was sufficiently visualized to perform angioplasty. No periprocedural target lesion complications were seen in any cases. Pushability and trackability tests showed good force transmission along a tortuous path with diagnostic catheters, and balanced force-displacement curves from three-point bending tests and distal tip softness tests. Angioplasty with stenting can be performed safely through 6F Cordis ® infiniti diagnostic catheters when difficulty in engaging guide catheters is encountered.

    -seal-off primary patency vs. secondary patency at 90, 180 and 360 days were 66.7 ± 11.1% vs. 94.4 ± 5.4%; 33.3 ± 11.1% vs. 83.3 ± 8.8%; and 13.3 ± 8.5% vs. 63.3 ± 12.1%, respectively. Our results suggest that the NBCA seal-off technique is effective for immediate control of a venous rupture irresponsive to prolonged balloon tamponade, during interventions for hemodialysis accesses. Both high technical and clinical success rates can be achieved. However, the treatment is not durable, and about 40% of the completely sealed off accesses are associated with developed delayed pseudoaneurysms in a 2-month of follow-up. Further repair of the vascular tear site, with surgery or stent-graft insertion, is often necessary.

    Peripherally inserted central catheters (PICCs) are considered a safe method to provide long-term antibiotic therapy, chemotherapy and nutrition support. Deep venous thrombosis (DVT) is a complication that requires early PICC removal, may extend hospitalization and can result in pulmonary embolism. PICC insertion teams strive to understand risk factors and develop methods to prevent DVTs. However, they can only manage what they can measure. At LDS Hospital, identification of PICC associated DVTs was dependent on verbal notification or manual surveillance of more than a thousand free-text vascular reports. Accurate DVT rates were not known which hindered prevention. We describe the development of a computer application (PICC-DVT monitor) to identify PICC associated DVTs each day. A one-year evaluation of the monitor by the PICC team and a review of 445 random vascular reports found a positive predictive value of 98%, sensitivity of 94%, specificity of 100% and a PICC team associated DVT rate of 2.8%.

    Full Text Available We aimed to investigate the incidence and risk factors associated with nonselective removal of peripherally inserted central venous catheter (PICC in neonates. In this prospective cohort study, neonates who underwent PICC placement at neonatal intensive care units (NICUs in China from October 2012 to November 2015 were included. The patient demographics, catheter characteristics, catheter duration, PICC insertion site, indication for PICC insertion, infuscate composition, PICC tip location, and catheter complications were recorded in a computerized database. Risk factors for nonselective removal were analyzed. A total of 497 PICCs were placed in 496 neonates. Nonselective removal occurred in 9.3% of PICCs during 10,540 catheter-days (4.6 nonselective removals per 1,000 catheter-days. These included occlusion (3%, infection (1.4%, leakage (2.0%, phlebitis (0.6%, displacement (1%, pleural effusion(0.6%, and breaks (0.6%. Noncentral tip position was independently associated with an increased risk of nonselective removal (odds ratio 2.621; 95% confidence interval, 1.258-5.461 after adjusting for gestational age, sex, birth weight, and PICC dwell time. No significant differences in the rate of complications occurred between silastic and polyurethane PICC or different insertion sites. Noncentral PICC tip position was the only independent risk factor for nonselective removal of PICC.

    Hickman catheter inserter has previously been predominantly accomplished surgically by means of venous cutdown or percutaneous placement in the operating room. The authors describe their method and results for 55 consecutive percutaneous placements of Hickman catheters in the interventional radiology suite. Complication rates were comparable to those for surgical techniques. Radiologic placement resulted in increased convenience, decreased time and cost of insertion, and super fluoroscopic control of catheter placement and any special manipulations. Modern angiographic materials provide safer access to the subclavian vein than traditional methods. The authors conclude that radiologic placement of Hickman catheters offers significant advantages over traditional surgical placement

    Catheter-associated urinary tract infections (CAUTIs) are among the most common healthcare-associated infections. Antiseptic cleaning of the meatal area before and during catheter use may reduce the risk of CAUTIs. To undertake a systematic review of the literature and meta-analysis of studies investigating the effectiveness of antiseptic cleaning before urinary catheter insertion and during catheter use for prevention of CAUTIs. Electronic databases were searched to identify randomized controlled trials. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated and compared across intervention and control groups using DerSimonian-Laird random-effects model. Subgroup analyses were performed. Heterogeneity was estimated using the I 2 statistic. In total, 2665 potential papers were identified; of these, 14 studies were eligible for inclusion. There was no difference in the incidence of CAUTIs when comparing antiseptic and non-antiseptic agents (pooled OR 0.90, 95% CI 0.73-1.10; P=0.31), or when comparing different agents: povidone-iodine vs routine care; povidone-iodine vs soap and water; chlorhexidine vs water; povidone-iodine vs saline; povidone-iodine vs water; and green soap and water vs routine care (P>0.05 for all). Comparison of an antibacterial agent with routine care indicated near significance (P=0.06). There was no evidence of heterogeneity (I 2 =0%; P>0.05). Subgroup analyses showed no difference in the incidence of CAUTIs in terms of country, setting, risk of bias, sex and frequency of administration. There were no differences in CAUTI rates, although methodological issues hamper generalizability of this finding. Antibacterial agents may prove to be significant in a well-conducted study. The present results provide good evidence to inform infection control guidelines in catheter management. Copyright © 2016 The Healthcare Infection Society. Published by Elsevier Ltd.

    Objective: To study the feasibility, complications, mid- and long-term advantages of peripherally inserted central catheters (PICC) compared with central venous access assisted with X-ray. Methods: From Jan 1997 to Dec 1998, the authors conducted a study in 60 patients with placed PICC lines and 60 patients with central lines. Study variables included tip placement and complication rates. Results: Tere were on significant differences between PICC and CVC in the successful placement 95.0% and 88.3%, t = 1.745, P 0.19; the mean duration 13(6-98) days and 14 (7-104) days, F = 0.049, P = 0.83; the total occlusion rate 6.7% (4/60) and 5.0%(3/60), t = 0.152, P = 0.70. In PICC patients, the occlusion rate was slightly higher in 3 Fr (20-gauge) catheter (3/20, 15.0%) than in 4 Fr(18-gauge) catheters (1/20, 5.0%), t = 1.111, P=0.29. Phlebitis occurred in 5.0% of patients (3/60) and one catheter fracture was happened on the catheter hub junction (1.7%). In 3 catheter tips dislocation cases, the catheter tips were moved to the optional position assisted with X-ray image. In CVC group, pneumothorax happened in 1 case (1.7%). In 4 catheter dislocation cases, the catheters were with drawn. No catheter-related sepsis and hemo-pneumothorax happened in both group patients. Conclusions: Both PICC and CVC can be acceptable in clinical use. PICC assisted with X-ray possesses the advantages of less trauma, accurate localization preventing some possible severe complications of central venous access such as pneumothorax. The new method provides a reliable, effective venous access for mid-and long-term usage in patients receiving a variety of solutions, primarily parenteral alimentation, chemotherapy or antibiotic infusion

    2005-01-01

    Pulmonary embolism is a common condition in which diagnostic and therapeutic delays contribute to substantial morbidity and mortality. Clinical diagnosis is difficult because the signs and symptoms re unspecific, and a differential diagnosis is extensive, including pneumonia or bronchitis, asthma, myocardial infraction, pulmonary edema, anxiety, dissection of the aorta, pericardial tamponade, lung cancer, primary pulmonary hypertension, rib fracture, and pneumothorax. The purpose of the study was to present the use of CT in diagnosing acute pulmonary embolism. A group of 23 patients with clinically suspected pulmonary embolism underwent CT examination with a helical CT scanner (Somatom Emotion, Siemens) before and after administration of 150 ml of Ultravist. Pulmonary embolism was found in the CT examinations of 13 patients. In two of these it was a central filling defect. Amputation of the artery was found in one. Parietal filling defect in three patients formed an acute angle with the vessel walls. Saddle emboli appearing as filling defects in the contrast column that hung over vessel bifurcations was found in two patients. In five patients,emboli were found in small segmental arteries. CT provides information not only on the pulmonary arteries, but also on the lung parenchyma, hila, mediastinum, and the heart. Alternative findings may be identified by CT chest examination, stablishing alternative diagnoses, including pulmonary disorders (such as pneumonia or fibrosis), pleural abnormalities, and cardiovascular disease (such as aortic dissection or pericardial tamponade). Another advantage of the CT is its widespread availability.(author)

    Full Text Available We investigated the mobility of a temperature-sensitive poloxamer/Alginate/CaCl2 mixture (PACM in relation to gravity and cardiac motion and the efficacy of PACM on the prevention of pericardial adhesion in a supine rabbit model.A total of 50 rabbits were randomly divided into two groups according to materials applied after epicardial abrasion: PACM and dye mixture (group PD; n = 25 and saline as the control group (group CO; n = 25. In group PD, rabbits were maintained in a supine position with appropriate sedation, and location of mixture of PACM and dye was assessed by CT scan at the immediate postoperative period and 12 hours after surgery. The grade of adhesions was evaluated macroscopically and microscopically two weeks after surgery.In group PD, enhancement was localized in the anterior pericardial space, where PACM and dye mixture was applied, on immediate post-surgical CT scans. However, the volume of the enhancement was significantly decreased at the anterior pericardial space 12 hours later (P < .001. Two weeks after surgery, group PD had significantly lower macroscopic adhesion score (P = .002 and fibrosis score (P = .018 than did group CO. Inflammation score and expression of anti-macrophage antibody in group PD were lower than those in group CO, although the differences were not significant.In a supine rabbit model study, the anti-adhesion effect was maintained at the area of PACM application, although PACM shifted with gravity and heart motion. For more potent pericardial adhesion prevention, further research and development on the maintenance of anti-adhesion material position are required.

    We present the case of a 63-year-old woman with a remote history of supraventricular tachycardia and hyperlipidemia, who presented with recurrent episodes of acute-onset chest pain. An electrocardiogram showed no evidence of acute coronary syndrome. A chest radiograph revealed a prominent right-sided heart border. A suspected congenital pericardial cyst was identified on a computed tomographic chest scan, and stranding was noted around the cyst. The patient was treated with nonsteroidal anti-inflammatory drugs, and the pain initially abated. Another flare-up was treated similarly. Cardiac magnetic resonance imaging was then performed after symptoms had resolved, and no evidence of the cyst was seen. The suspected cause of the patient's chest pain was acute inflammation of a congenital pericardial cyst with subsequent rupture and resolution of symptoms.

    Pericardium is a structure that can be primarily affected by a series of different agents and in a secondary way by systemic processes. Its response is not specific and in general it corresponds to an inflammatory process that can be acute, chronic or recurrent. The recognition of these pathologies is of vital significance in the making of a right therapeutic approach. Some basic orientations for the correct classification, diagnosis and therapy of main pericardial syndromes, based on clinical and etiological aspects and para clinical available aids are presented. Likewise, some recommendations for the specific treatment of each one of the main entities usually affecting the pericardium are given. Next, a brief mention of some pathophysiological aspects of acute myocarditis, its main etiologies, and the treatment of the cardiac failure secondary to the disease with its specific differences, is made, and the controversy on its handling with immuno suppressors and the experimental therapy measures are studied in depth

    Full Text Available Uterine artery embolization is the most common treatment for uterine vascular abnormalities. Herein, we report the successful use of dilation and evacuation as a treatment for uterine artery pseudoaneurysm. A 36-year-old woman complained of vaginal bleeding after an uncomplicated vaginal delivery. Ultrasonography showed a 12.8-mm anechoic area inside the uterus. Color Doppler revealed a to-and-fro sign, indicating an arteriovenous malformation. A blood test showed a low level of human chorionic gonadotropin. Therefore, a diagnosis of early uterine artery pseudoaneurysm following spontaneous delivery was suspected. Under monitoring with transabdominal color Doppler sonography, intrauterine balloon tamponade induced complete disappearance of abnormal blood flow. With bleeding determined to be under control with balloon tamponade, dilation and evacuation was performed. The patient had a favorable postoperative course.

    The large number of pace-makers introduced transvenously has resulted in increasing the number of complications, amongst which infections and dislocations are prominent. It is usually necessary to remove the electrode, which can be attempted percutaneously by using a Dormia basket, a loop or forceps. Amongst the complications of this procedure are tears to the myocardium, with the risk of pericardial tamponade, or tears of the tricuspid valve leading to tricuspid insufficiency. Consequently, thoracic surgical intervention should be available if necessary. Four successful procedures are described. (orig.) [de

    Bloodstream infection due to Rhodotorula glutinis is extremely rare and mostly associated with underlying immunosuppression or cancer. Vascular access devices provide the necessary surfaces for biofilm formation and are currently responsible for a significant percentage of human infections. In this work, we describe a rare case of central venous catheter-related Rhodotorula glutinis fungemia in a female patient with acute myelogenous leukemia in remission. The timely removal of central venous catheter was an essential element for overcoming this CVC-related Rhodotorula fungemia.

    Purpose: To assess the incidence of infections and its influence on the survival of radiologically inserted Hickman catheters (HCs) in patients with hematologic disorders and to determine factors associated with premature HC removal. Methods: Survival and complications of 175 HCs in 115 patients were studied retrospectively. To describe the data the Kaplan-Meier method and the log-rank test were used, using the date of HC removal due to HC-related infection as endpoint. A stratified Cox regression model was used to determine explanatory factors. Results: Seventy (40%) HCs were removed prematurely because of proven or probable HC-related infections. The incidence of infection leading to HC removal was 4.78 per 1000 catheter-days for proven HC infections. Univariate analysis revealed that acute myeloid leukemia, acute lymphocytic leukemia, or treatment for these diseases, gender, each subsequent catheter in the same patient and insertion site increased the risk of premature removal of the catheter due to infection. Conclusion: Infection is a major problem in patients with HCs. Unfortunately, the factors associated with increased infection rates that were found in this study cannot be influenced. Further studies are necessary to determine the role of environmental conditions in a radiology suite in relation to the risk of developing a catheter-related infection

    During percutaneous transluminal coronary angioplasty, the appearance of persistent staining in the vessel by contrast media suggests coronary dissection. We report seven patients in whom a false image of severe coronary dissection was observed during angioplasty performed with the new Monorail balloon catheter. This image emerges at the moment of balloon inflation, is distally located to the balloon, and disappears with balloon catheter deflation. No complications were associated with the appearance of this image.

    Objective: To evaluate the radiofrequency catheter ablation for type I atrial flutter through application of Holo catheter labelling with anatomic imaging localization to ablate the isthmus of IVCTA during complete double-way block. Methods: Eleven cases with type I atrial flutter undergone Holo catheter labelling technique and consecution with conduction time change of coronary venous sinus orifice with-right atrial lower lateral wall pace excitation, were performed with radiofrequency catheter ablation for the isthmus outcoming with complete double-way conduction block. Results: All together 11 cases with 4 of atrial flutter and 7 of sinus rhythm were undergone radiofrequency catheter ablation resulting with double-way conduction block of the isthmus accompanied by prolongation of right atrial conduction time 56.0 ± 2.3 ms and 53.0 ± 4.6 ms respectively. The right atrial excitation appeared to be in clockwise and counter-clockwise of single direction. No recurrence occurred during 3-34 months follow up with only one showing atrial fibrillation. Conclusions: The application of Holo catheter labelling technique with anatomic imaging localization to achieve the double-way conduction block by radiofrequency catheter ablation of TVC-TA isthmus, is a reliable method for treating atrial flutter

    Objective Postpericardiotomy syndrome (PPS), which is thought to be related to autoimmune phenomena, represents a common postoperative complication in cardiac surgery. Late pericardial effusions after cardiac surgery are usually related to PPS and can progress to cardiac tamponade. Preventive measures can reduce postoperative morbidity and mortality related to PPS. In a previous study, diclofenac was suggested to ameliorate autoimmune diseases. The aim of this study was to determine whether postoperative use of diclofenac is effective in preventing early PPS after cardiac surgery. Methods A total of 100 patients who were administered oral diclofenac for postoperative analgesia after cardiac surgery and until hospital discharge were included in this retrospective study. As well, 100 patients undergoing cardiac surgery who were not administered nonsteroidal anti-inflammatory drugs were included as the control group. The existence and severity of pericardial effusion were determined by echocardiography. The existence and severity of pleural effusion were determined by chest X-ray. Results PPS incidence was significantly lower in patients who received diclofenac (20% vs 43%) (Pdiclofenac had a significantly lower incidence of pericardial effusion (15% vs 30%) (P=0.01). Although not statistically significant, pericardial and pleural effusion was more severe in the control group than in the diclofenac group. The mean duration of diclofenac treatment was 5.11±0.47 days in patients with PPS and 5.27±0.61 days in patients who did not have PPS (P=0.07). Logistic regression analysis demonstrated that diclofenac administration (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.18–0.65, P=0.001) was independently associated with PPS occurrence. Conclusion Postoperative administration of diclofenac may have a protective role against the development of PPS after cardiac surgery. PMID:26170687

    Peripherally Inserted Central Catheters (PICCs) are increasingly being used to provide short to medium-term central venous access. The current study was designed to test the hypothesis that PICC valve technology does not influence PICC occlusion rates. Intensive care unit (ICU) patients who required a PICC were randomized to one of three types of dual lumen PICC (open ended non-valved, Groshong valve, PASV valve). PICC occlusions were recorded and managed with a protocol that used urokinase. A total of 102 patients were recruited to the study. The overall risk of occlusion per catheter was 35% (95% CI 26% to 44%). The overall rate of occlusion was 76 occlusions per 1000 catheter days (95% CI 61 to 95). Presence or type of valve did not significantly influence this rate (open-ended non-valved PICC 38% of catheters, 79 occlusions per 1000 catheter days; Groshong 38% of catheters, 60 occlusions per 1000 catheter days; PASV 27% of catheters, 99 occlusions per 1000 catheter days). The dose of urokinase required to treat PICC occlusions did not significantly differ between PICC types. Valved PICCs do not appear to influence PICC occlusion rates.

    Sheikh Khalifa Medical City (SKMC) in Abu Dhabi is the main tertiary care referral hospital in the United Arab Emirates (UAE) with 560 bed capacity with a high occupancy rate. SKMC senior management has made a commitment to make quality and patient safety a top priority. Preventing health care associated infections, including Catheter Associated Urinary Tract Infection (CAUTI), is a high priority for our hospital. In order to improve CAUTI rates a multidisciplinary task force team was formed and led this performance improvement project. The purpose of this publication is to indicate the quality improvement interventions implemented to reduce CAUTI rates and the outcome of those interventions. We chose to conduct the pilot study in General Medicine as it is the busiest department in the hospital, with an average of 390 patients admitted per month during the study period. The study period was from March 2015 till April 2016. Our aim was to reduce CAUTI rates per 1000 device days in the medical units. Implemented interventions resulted in a reduction of CAUTI from 6.8 per 1000 device days in March 2015 to zero CAUTI in February through April 2016. PMID:28469893

    We examine the complication and continence rates with early catheter removal (day 3 or 4) after radical retropubic prostatectomy. A total of 365 patients with localized prostate cancer underwent radical retropubic prostatectomy at Indiana University Hospital with planned urethral catheter removal before discharge home. Low pressure cystograms were performed on postoperative day 3 or 4 to determine if catheter removal was possible. A subset of patients were analyzed using a validated prostate cancer specific questionnaire (University of California, Los Angeles Prostate Cancer Symptom Index) to determine quality of life outcomes. The catheter was removed on postoperative day 3 or 4 in 263 patients (72%). The reasons for leaving the catheter indwelling were significant leak on cystogram or excessive suprapubic drainage (21%), extensive bladder neck reconstruction (1%) and prolonged hospitalization because of an ileus or other complicating factor (6%). Thirteen patients (3.6%) were either unable to void after catheter removal or presented with retention (not associated with hematuria or clots) after hospital discharge, requiring reinsertion of the Foley catheter. A total of 41 patients (11%) had either an early or late complication (excluding incontinence). There were 3 complications (0.8%) that were considered major because they were potentially life threatening or required a return to the operating room. A pelvic abscess developed in 2 patients and a lymphocele in 1, which required percutaneous drainage. After at least 6 months (mean 20.9 months) 140 patients (89.2%) and 14 (8.9%) reported excellent and good continence, respectively. The patient questionnaire demonstrated bother scores to be minimal to no bother for 95% to 98% of patients at 6 and 12 months. This study confirms that it is safe to remove catheters in most patients 3 to 4 days after prostatectomy if a cystogram demonstrates no extravasation.

    Full Text Available Background: It has been shown previously that conventional ventilation delivered through a long cuffed endotracheal tube is associated with a high flow-resistance and frequent perioperative complications. Aim: We attempted to supersede the conventional ventilation by high-frequency jet ventilation through a catheter (HFJV-C and assess safety of the procedure. Material and methods: Using a translaryngeal tracheostomy kit, we performed a translaryngeal (Fantoni tracheostomy (TLT. Subsequently, we introduced a special 2-way prototype ventilatory catheter into the trachea via the TLT under bronchoscopic control. Satisfactory HFJV-C ventilation through the catheter was achieved in 218 patients. Results: There were no significant adverse effects on vital signs observed in the cohort during the study. The pH, SpO2, PaO2, and PaCO2 did not change significantly following the HFJV-C. The intrinsic PEEPi measured in trachea did not exceed 4—5 cm H2O during its application, which was significantly less than during the classical ventilation via the endotracheal tube fluctuating between 12 and 17 cm H2O. No serious medical complications occurred. Conclusion: The HFJV during Fantoni’s tracheostomy using the catheter HFJV-C proved to be a safe and effective method of lung ventilation at the intensive care unit. Key words: Translaryngeal tracheostomy, HFJV via catheter.

    Introduction: Congenital pericardial defect (CPD) is an uncommon anomaly. If once cardiac herniation occurs, it threatens life. We report a case of left-sided pneumothorax with consequent protrusion of the heart into left thoracic cavity through not only a large CPD but also congenital pleuropericardium window. Case presentation: A 67-year-old man presenting with sudden-onset left-sided chest pain and slight dyspnea was referred to our hospital. Chest X-ray showed a left lung collapse, and also revealed a pneumopericardium along the right border of the ascending aorta. Subsequent computed tomography (CT) scan revealed that the heart was displaced into the left hemithorax. Thus, we diagnosed the patient with pneumothorax and a defect of the pericardial and mediastinal pleurae. Subsequently, a chest tube was inserted into the left thoracic cavity, and the collapsed lung was promptly inflated. The cardiac position was reinstated within mediastinum as evidenced by follow-up CT scan. The QRS axis on his electrocardiogram (ECG) was altered from 52° to 73°. Together with the cardiac relocation evidenced by the QRS axis shift on ECG and findings of CT, we determined that there was a low potential for complications and opted against surgical repair. Discussion: When the CPD is sufficiently large, surgical intervention is not necessary. The size of the CPD can be assessed not only by CT findings, but the alteration of the QRS axis on ECG also provides useful information whether cardiac herniation can be resolved by the inflated lung. - Highlights: • We reported a case of congenital pericardial defect (CPD) with pneumothorax. • We described how to manage to alleviate life-threatening complications. • The size of CPD was assessed by CT findings and the alteration of QRS axis on ECG

    To investigates the different methods of balloon deflation, types of urinary catheters and exposure to urine media in catheter balloon cuffing. Bardex®, Bard-Lubri-Sil®, Argyle®, Releen® and Biocath® were tested in sterile and E.Coli inoculated urine at 0, 14 and 28 days. Catheter deflation was performed with active deflation; passive deflation; passive auto-deflation; and excision of the balloon inflow channel. Balloon cuffing was assessed objectively by running the deflated balloon over a plate of agar and subjectively by 3 independent observers. Bardex®, Argyle® and Biocath® showed greater degree of catheter balloon cuffing (p deflation was the worst method (p 0.05). Linear regression model analysis confirmed time as the most significant factor. The duration of catheters exposure, different deflation methods and types of catheters tested contributed significantly to catheter balloon cuffing (p < 0.01).

  12. Complications of Peripherally Inserted Central Venous Catheters: A Retrospective Cohort Study.

    Full Text Available The use of venous catheters is a widespread practice, especially in oncological and oncohematological units. The objective of this study was to evaluate the complications associated with peripherally inserted central catheters (PICCs in a cohort of patients.In this retrospective cohort study, we included all patient carrying PICCs (n = 603 inserted at our institute between October 2010 and December 2013. The main variables collected were medical diagnosis, catheter care, location, duration of catheterization, reasons for catheter removal, complications, and nursing care. Complications were classified as infection, thrombosis, phlebitis, migration, edema, and/or ecchymosis.All patients were treated according to the same "nursing care" protocol. The incidence rate of complications was two cases per 1000 days of catheter duration. The most relevant complications were infection and thrombosis, both with an incidence of 0.17 cases per 1000 days of the total catheterization period. The total average duration of catheterization was 170 days [SD 6.06]. Additionally to "end of treatment" (48.42% and "exitus", (22.53% the most frequent cause of removal was migration (displacement towards the exterior of the catheter (5.80%.PICCs are safe devices that allow the administration of long-term treatment and preserve the integrity of the venous system of the patient. Proper care of the catheter is very important to improve the quality life of patients with oncologic and hematologic conditions. Therefore, correct training of professionals and patients as well as following the latest scientific recommendations are particularly relevant.

    Parenteral nutrition for neonates may be delivered via a short peripheral cannula or a central venous catheter. The latter may either be inserted via the umbilicus or percutaneously. Because of the complications associated with umbilical venous catheter use, many neonatal units prefer to use percutaneously inserted catheters following the initial stabilisation period. The method of parenteral nutrition delivery may affect nutrient input and consequently growth and development. Although potentially more difficult to place, percutaneous central venous catheters may be more stable than peripheral cannulae, and need less frequent replacement. These delivery methods may also be associated with different risks of adverse events, including acquired systemic infection and extravasation injury. To determine the effect of infusion via a percutaneous central venous catheter versus a peripheral cannula on nutrient input, growth and development, and complications including systemic infection, or extravasation injuries in newborn infants who require parenteral nutrition. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007), MEDLINE (1966 - February 2007), EMBASE (1980 - February 2007), conference proceedings, and previous reviews. Randomised controlled trials that compared the effect of delivering parenteral nutrition via a percutaneous central venous catheter versus a peripheral cannulae in neonates. Data were extracted the data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author, and synthesis of data using relative risk, risk difference and mean difference. Four trials eligible for inclusion were found. These trials recruited a total of 368 infants and reported a number of different outcomes. One study showed that the use of a percutaneous

    Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans-radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother-in-daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter. Using a balloon tracking technique over a guidewire, a GuideLiner was placed as an extension of the guiding catheter and facilitated TR-PCI by overcoming technical challenges associated with difficult anatomy. © 2018 Wiley Periodicals, Inc.

    Sinus node dysfunction requiring pacemaker implantation is commonly associated with atrial fibrillation (AF), but may not be clinically apparent until restoration of sinus rhythm with ablation or cardioversion. We sought to determine frequency, time course, and predictors for pacemaker implantation after catheter ablation, and to compare the overall rates to a matched cardioversion cohort. We conducted a retrospective analysis using a large US commercial insurance database and identified 12,158 AF patients who underwent catheter ablation between January 1, 2005 and December 31, 2012. Over an average of 2.4 years of follow-up, 5.6 % of the patients underwent pacemaker implantation. Using the Cox proportional hazards models, we found that risk of risks of pacemaker implantation was associated with older age (50-64 and ≥65 versus pacemaker implantation between ablation patients and propensity score (PS)-matched cardioversion groups (3.5 versus. 4.1 % at 1 year and 8.8 versus 8.3 % at 5 years). Overall, pacemaker implantation occurs in about 1/28 patients within 1 year of catheter ablation. The overall implantation rate decreased between 2005 and 2012. Furthermore, the risk after ablation is similar to cardioversion, suggesting that patients require pacing due to a common underlying electrophysiologic substrate, rather than the ablation itself.

    Catheter-related blood stream infections are a morbid complication of central venous catheters. This review will highlight a comprehensive approach demonstrated to prevent catheter-related blood stream infections. Elements of prevention important to inserting a central venous catheter include proper hand hygiene, use of full barrier precautions, appropriate skin preparation with 2% chlorhexidine, and using the subclavian vein as the preferred anatomic site. Rigorous attention needs to be given to dressing care, and there should be daily assessment of the need for central venous catheters, with prompt removal as soon as is practicable. Healthcare workers should be educated routinely on methods to prevent catheter-related blood stream infections. If rates remain higher than benchmark levels despite proper bedside practice, antiseptic or antibiotic-impregnated catheters can also prevent infections effectively. A recent program utilizing these practices in 103 ICUs in Michigan resulted in a 66% decrease in infection rates. There is increasing recognition that a comprehensive strategy to prevent catheter-related blood stream infections can prevent most infections, if not all. This suggests that thousands of infections can potentially be averted if the simple practices outlined herein are followed.

    Peritoneal dialysis (PD) is limited mainly by a higher technique failure rate as compared to hemodialysis (HD), catheter malfunction being an important reason. Intra- and extra-peritoneal catheter configuration may be associated with mechanical and infectious complications affecting method survival. We report our experience with two extra-peritoneal catheter configurations: the straight and the swan-neck (SN) catheters. A total of 85 consecutive patients, 58 males and 27 females were included in the study. Among them, 26 were diabetics; 52 were treated with automated PD (APD) and 33 with continuous ambulatory PD (CAPD). Straight catheters were used in 38 patients (straight group) and SN catheters in 47 patients (SN group). Straight catheters were mostly used in the first 6-year period while SN catheters in the last 6-year period. The baseline demographics were similar between the two groups. A significantly higher frequency of APD use was observed in SN group. Technique survival was better with SN versus straight (log-rank test, P = 0.01) while patient and catheter survival were similar. A better technique survival is noted in our group of patients with SN catheters. An additional factor could be the significantly higher frequency of APD use in this group. Changes in PD solutions' composition could also contribute to improvement in technique survival. The outcome for patients and catheter types used was similar.

    The objective of this study was to determine whether severe neutropenia on the day of port-a-catheter (PORT) insertion was a risk factor for catheter-associated infection (CAI) in children with acute lymphoblastic leukemia (ALL). This was a retrospective study of children with ALL who had a PORT insertion between January 2005 and August 2008. Early (≤ 30 days) and late (>30 days) postprocedure complications were reviewed. The length of follow-up ranged between 7 months and 42 months. In total, 192 PORTs were inserted in 179 children. There were 43 CAIs (22%), and the infection rate was 0.35 per 1000 catheter-days. The CAI rate (15%) in children who had severe neutropenia on the day of the procedure did not differ statistically from the CAI rate (24%) in children who did not have severe neutropenia (P = .137). Conversely, patients with severe neutropenia who had a CAI were more likely to have their PORT removed (P = .019). The most common organisms to cause catheter removal were coagulase-negative Staphylococcus and Staphylococcus aureus. Patients with high-risk ALL had a statistically significant higher incidence of late CAI than patients with standard-risk ALL (P = .012). Age (P = .272), positive blood culture preprocedure (P = 1.0), and dexamethasone use (P = .201) were not risk factors for CAI. Patients who had an early CAI did not have a greater chance of having a late CAI. The catheter infection-free survival rate at 1 year was 88.6%. The current results indicated that severe neutropenia on the day of PORT insertion does not increase the risk of CAI in children with ALL. © 2010 American Cancer Society.

    The accuracy of Gram staining of blood drawn from catheters used to administer total parenteral nutrition was compared with paired quantitative blood cultures for the diagnosis of catheter-related sepsis. Gram staining was positive in 11 of 18 episodes of catheter-related sepsis documented by quantitative culture (sensitivity, 61%) but in none of the 5 episodes of fever unrelated to catheter infection. Thus, this procedure enabled the rapid presumptive diagnosis and guidance of antimicrobial therapy for total parenteral nutrition catheter sepsis, with a positive predictive value of 100% and a negative predictive value of 42%.

    Full Text Available Cardiac injury after blunt trauma is common but underreported. Common cardiac trauma after the blunt chest injury (BCI is cardiac contusion; it is very rare to have cardiac valve injury. The mitral valve injury during chest trauma occurs when extreme pressure is applied at early systole during the isovolumic contraction between the closure of the mitral valve and the opening of the aortic valve. Traumatic mitral valve injury can involve valve leaflet, chordae tendineae, or papillary muscles. For the diagnosis of mitral valve injury, a high index of suspicion is required, as in polytrauma patients, other obvious severe injuries will divert the attention of the treating physician. Clinical picture of patients with mitral valve injury may vary from none to cardiogenic shock. The echocardiogram is the main diagnostic modality of mitral valve injuries. Patient’s clinical condition will dictate the timing and type of surgery or medical therapy. We report a case of mitral valve and pericardial injury in a polytrauma patient, successfully treated in our intensive care unit.

    Full Text Available ObjectiveTo investigate the possible risk factors for rebleeding after splenectomy and pericardial devascularization in the treatment of portal hypertension due to liver cirrhosis, and to provide a certain basis for reducing the incidence of digestive tract re-hemorrhage for these patients. MethodsA retrospective analysis was performed on 238 cirrhotic patients with portal hypertension who underwent splenectomy and pericardial devascularization in the First Hospital of Lanzhou University from December 2003 to December 2013. These patients were divided into postoperative rebleeding group (n=32 and non-bleeding group (n=206. Univariate analysis (t test or chi-square test and multivariate logistic regression analysis were performed to investigate the risk factors for rebleeding after splenectomy and pericardial devascularization. ResultsOf the 32 patients with postoperative rebleeding, 17 had esophagogastric variceal bleeding, 11 had bleeding due to portal hypertensive gastropathy, and 4 had stress ulcer bleeding. The univariate analysis showed that there were significant differences between the two groups in the following factors: Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, pathological changes of the gastric mucosa, platelet count, prothrombin time (PT, activated partial thromboplastin time (APTT, and presence of diabetes (all P<0.05. The multivariate logistic regression analysis suggested that the significant independent influential factors for postoperative rebleeding were presence of diabetes, Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, diffuse lesion of the gastric mucosa, PT, and APTT. ConclusionFor cirrhotic patients with portal hypertension, the appropriate methods for managing these risk factors are of great clinical significance for preventing rebleeding after splenectomy and pericardial devascularization.

    In January 2015, the Centers for Disease Control and Prevention (CDC)/National Health Safety Network (NHSN) changed the definition of catheter-associated urinary tract infection (CAUTI). We evaluated the outcomes of a robust CAUTI prevention program when we performed surveillance using the old definition (before 2015) versus the new definition (after 2015). This is the first study to evaluate how the change in CDC/NHSN definitions affected the outcomes of a CAUTI reduction program. Baseline was from January 2012 to September 2014; the intervention period was from October 2014 to February 2016. Staff nurses were trained to be liaisons of infection prevention (Link Nurses) with clearly defined CAUTI prevention goals and with ongoing monthly activities. CAUTI incidence per 1000 catheter days was compared between the baseline and intervention periods, using the 2 definitions. With the new definition, CAUTIs decreased by 33%, from 2.69 to 1.81 cases per 1000 catheter days (incidence rate ratio [IRR] = 0.67; 95% confidence interval [CI]: 0.48-0.93; P definition, CAUTIs increased by 12%, from 3.38 to 3.80 cases per 1000 catheter days (IRR = 1.12; 95% CI: 0.88-1.43; P = .348). We aggressively targeted CAUTI prevention, but a reduction was observed only with the new definition. Our findings stress the importance of having a reasonably accurate surveillance definition to monitor infection prevention initiatives.

    The etiology and laboratory characteristics of large symptomatic pericardial effusion (LSPE) in the Western world have evolved over the years, and vary between regions, community and tertiary hospitals. We reviewed data of 86 consecutive patients who underwent pericardiocentesis or pericardial window due to LSPE in a community hospital from 2001 to 2010. The characteristics of the PE including chemistry, hematology, bacteriology, serology and cytology have been analyzed. We correlated the etiologies of PE with age, gender and clinical presentation. The most frequent etiology of LSPE was idiopathic [36% (77% with a clinical diagnosis of pericarditis)], followed by malignancy (31.4%), ischemic heart disease (16.3%), renal failure (4.6%), trauma (4.6%) and autoimmune disease (4.6%). The average age of all the etiological groups excluding trauma was over 50 years. Laboratory tests did not modify the pre-procedure diagnosis in any of the patients. The most frequent presenting symptom was dyspnea (76.6%). Chest pain was mostly common in patients with idiopathic etiology (58.06%). The most frequent medical condition associated with LSPE was the use of anticoagulant or antiplatelet drugs (31.40%), especially aspirin, and in those, the PE tended to be bloody (73%, P = 0.11). Most of the effusions were exudates (70.9%). PE due to renal failure was the largest (1467 ± 1387 ml). The spectrum of etiologies of LSPE in a community hospital in the Western world in the contemporary era is continuously evolving. The most frequent etiology is now idiopathic, followed by malignancy. Routine laboratory testing still rarely modifies the pre-procedure diagnosis.

    Nontyphoidal Salmonella, especially Salmonella enterica, is a rare cause of endocarditis and pericarditis that carries a high mortality rate. Proposed predisposing conditions include immunodeficiency states, congenital heart defects, and cardiac valve diseases. We present 2 cases of cardiovascular salmonellosis. The first case is that of a 73-year-old woman with mechanical mitral and bioprosthetic aortic valves who died from sequelae of nontyphoidal Salmonella mitral valve vegetation, aortic valve abscess, and sepsis. The second case is that of a 62-year-old man with a recent systemic lupus erythematosus exacerbation treated with oral steroids, who presented with obstructive features of tamponade and sepsis secondary to a large S. enteritidis purulent pericardial cyst. He recovered after emergent pericardial drainage and antibiotic therapy. Identifying patients at risk of cardiovascular salmonellosis is important for early diagnosis and treatment to minimize sequelae and death. We reviewed the literature to identify the predisposing risk factors of nontyphoidal Salmonella cardiac infection. PMID:25120393

    A case of acute nonlymphocytic leukemia presenting as pericarditis is reported in a five-year-old boy. Initially, a clinical diagnosis of viral pericarditis was made, because the child did not demonstrate hematologic or clinical manifestations of leukemia. Acute undifferentiated or lymphocytic leukemia. Acute undifferentiated or lymphocytic leukemia was diagnosed one week after admission when his peripheral blood count became abnormal. The patient did not respond to vincristine and prednisone. When cytochemical evaluation indicated acute myelomonocytic leukemia, employment of cytosine arabinoside and 6-thioguanine was instituted and the child began to improve. Currently, he is still in good remission and has no evidence of recurrence of pericarditis, 1 1/2 years after his initial presentation. In reviewing the literature, we found 17 patients who had leukemic pericardial effusion with cardiac tamponade. There are three reported cases of young children with pericardial effusion as the initial manifestation of acute lymphocytic leukemia, but no reported cases due to nonlymphocytic leukemia, as in this child.

    Epiretinal membranes (ERM) are macular disorders leading to loss of vision and metamorphopsia. Vitrectomy with membrane peeling displays the gold standard of care. Aim of this study was to assess risk factors for postoperative intraretinal cystoid changes in a study population randomized for balanced salt solution and air-tamponade at the end of surgery. A prospective randomized study, including 69 eyes with idiopathic ERM. Standard 23-gauge three-port pars plana vitrectomy with membrane peeling, using intraoperative optical coherence tomography (OCT), was performed. Randomization for BSS and air-tamponade was performed prior to surgery. Best-corrected visual acuity improved from 32.9 letters to 45.1 letters 3 months after surgery. Presence of preoperative intraretinal cystoid changes was found to be the only risk factor for presence of postoperative intraretinal cystoid changes 3 months after surgery (p = 0.01; odds ratio: 8.0). Other possible risk factors such as combined phacoemulsification with 23G-ppv and membrane peeling (p = 0.16; odds ratio: 2.4), intraoperative subfoveal hyporeflective zones (p = 0.23; odds ratio: 2.6), age over 70 years (p = 0.29; odds ratio: 0.5) and air-tamponade (p = 0.59; odds ratio: 1.5) were not found to be significant. There is strong evidence that preoperative intraretinal cystoid changes lead to smaller benefit from surgery. © 2018 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    2011-01-01

    Phlebitis is a very common complication of the use of intravenous catheters. Two patients with an i.v. catheter complicated by thrombophlebitis are described. Patient A was immunocompromised due to chronic lymphatic leukaemia and developed septic thrombophlebitis with positive blood cultures for S. Aureus. Patient B was being treated with flucloxacillin because of an S. Aureus infection and developed chemical phlebitis. Septic phlebitis is rare, but potentially serious. Chemical or mechanical types of thrombophlebitis are usually less severe, but happen very frequently. Risk factors include: female sex, previous episode of phlebitis, insertion at (ventral) forearm, emergency placement and administration of antibiotics. Until recently, routine replacement of peripheral intravenous catheters after 72-96 h was recommended, but randomised controlled trials have not shown any benefit of this routine. A recent Cochrane Review recommends replacement of peripheral intravenous catheters when clinically indicated only.

    International guidelines recommend the use of a prophylactic antibiotic before the peritoneal dialysis (PD) catheter can be inserted. The main objective of this study was to assess whether this practice is associated with a lower risk of early peritonitis and to estimate the magnitude of the centre effect. A retrospective, multi-centric study was conducted, in which data from the French Language Peritoneal Dialysis Registry was analysed. Patients were separated into 2 groups based on whether or not prophylactic antibiotics were used prior to catheter placement. Out of the 2,014 patients who had a PD catheter placed between February 1, 2012 and December 31, 2014, 1,105 were given a prophylactic antibiotic. In a classical logit model, the use of prophylactic antibiotics was found to protect the individual against the risk of early peritonitis (OR 0.67, 95% CI 0.49-0.92). However, this association lost significance in a mixed logistic regression model with centre as a random effect: OR 0.73 (95% CI 0.48-1.09). Covariates associated with the risk of developing early peritonitis were age over 65: OR 0.73 (95% CI 0.39-0.85), body mass index over 35 kg/m2: OR 1.99 (95% CI 1.13-3.47), transfer to PD due to graft failure: OR 2.24 (95% CI 1.22-4.11), assisted PD: OR 1.96 (95% CI 1.31-2.93), and the use of the Moncrief technique: OR 3.07 (95% CI 1.85-5.11). There is a beneficial effect of prophylactic antibiotic used prior to peritoneal catheter placement, on the occurence of early peritonitis. However, the beneficial effect could be masked by a centre effect. © 2016 S. Karger AG, Basel.

    To retrospectively evaluate the use of Micronester coils in port-catheter implantation with the fixed catheter tip method in comparison with other previously used coils. The cohort of this study was 143 consecutive patients with unresectable advanced liver cancer for whom a port-catheter system was percutaneously implanted. In the most recent 32 patients, Micronester coils were used for catheter tip fixation. Details of embolic agents for fixation, persistent blood flow beyond the distal end of the indwelling catheter, and complications were compared between cases without and with Micronester coils. In all, percutaneous port-catheter placement was successful. Mean number of coils used for fixation was 4.2 without Micronester coils vs. 2.5 with Micronester coils. N-butyl cyanoacrylate (NBCA)-Lipiodol was additionally used for catheter tip fixation in 85.6% of 111 procedures without Micronester coils and in 50% of 32 using Micronester coils. The gastroduodenal artery beyond the distal end was not detected at the final examination after any procedure. Catheter dislocation occurred in five and hepatic arterial obstruction or severe stenosis in eight. The number of coils used and necessity of NBCA-Lipiodol could be decreased with usage of Micronester coils without decreasing fixation ability compared to other coils. (orig.)

    Fungal endocarditis (FE) is commonly regarded as a rare but fatal disease. The incidence of infective endocarditis (IE) in hemodialysis (HD) patients is thought to be obviously higher than that in the general population. Moreover, IE occurs more likely in HD patients with catheters. With the increase of HD population and extensive use of catheters in HD patients, FE, as a special form of IE, may increase and bring new challenges to clinicians. We reported a case of FE associated with catheter infection in a 44-year-old woman on HD. The risk factors and treatment strategies of FE in HD patients were discussed. © 2017 International Society for Hemodialysis.

    The purpose of this study was to describe the CT findings and clinical outcomes of nineteen patients with acute intramural hematoma (IMH) of the ascending aorta. Six patients underwent surgery on the emergency basis (3 patients) due to cardiac tamponade (n=2) and dilated aorta (n=1), and on the elective basis (3 patients) due to patent and enlarging false lumen. Among the 13 patients with medical management, four patients died from complications of IMH during the follow-up period (2 days-2.5 years). Transition to aortic dissection or enlargement of an intimal tear was noted in 5 patients (31%) in 1 to 6 weeks after onset. Three patients died of causes not related to IMH. Six patients had been alive 2 to 9 years after onset. Retrospective review revealed 10 patients (53%) as possible surgical candidates, and the other 9 patients as medically treated patients in the long-term follow-up. The surgical group showed cardiac tamponade or shock in 6 patients on admission and had pericardial effusion in all the patients on the initial CT scan. In the patients with acute IMH of the ascending aorta, surgery should be considered for severe clinical symptoms, pericardial effusion and large size of the ascending aorta (more than 4 cm) on CT scan, and for converting to a typical type A aortic dissection. CT scan had a major role in making an early diagnosis, in depicting a dangerous sign, and in monitoring its progression or resolution of IMH. (author)

    Twenty dogs with neoplasms requiring multiple radiation treatments received either percutaneous vascular access catheters (PVACs; Cook, Bloomington, IN) or subcutaneous vascular access ports (SVAPs; Vascular-Access-Ports, Norfolk Medical Products, Inc., Skokie, IL); 10 dogs were entered in each group. All catheters were implanted and removed aseptically and the catheter tips were cultured during implant removal. Complications with PVACs included mild incisional swelling and redness and accidental severance or rupture of the catheter. Complications with SVAPs included incisional or port swelling, bruising or redness, hematoma formation, and pain. Ports in 4 of these dogs could not be used for 1 to 3 days after surgery because of swelling and pain. Surgical wound complications, when pooled for comparison, occurred significantly more frequently with the SVAPs (P = .023). Wound complications associated with both catheters were self-limiting and resolved within 7 days. Bacterial cultures were positive in two PVACs and four SVAP tips, however, none of these dogs had clinical signs of infection or sepsis. Although both types of indwelling catheters were functional in a clinical setting, PVACs were preferred to SVAPs for dogs undergoing radiation therapy because of decreased time for implantation and fewer overall complications

    This study presents a cost-effectiveness analysis comparing hydrophilic coated to uncoated catheters for patients performing urinary intermittent catheterisation. A national budget impact analysis is also included to evaluate the impact of intermittent catheterisation for management of bladder dysfunctions over a period of 5 years. A Markov model (lifetime horizon, 1 year cycle length) was developed to project health outcomes (life years and quality-adjusted life years) and economic consequences related to patients using hydrophilic coated or uncoated catheters. The model was populated with catheter-related clinical efficacy data retrieved from randomised controlled trials and quality-of-life data (utility weights) from the literature. Cost data (EUR, 2015) were estimated on the basis of healthcare resource consumption derived from an e-survey addressed to key opinion leaders in the field. Italian Healthcare Service perspective. Patients with spinal cord injury performing intermittent urinary catheterisation in the home setting. Incremental cost-effectiveness and cost-utility ratios (ICER and ICUR) of hydrophilic coated versus uncoated catheters and associated healthcare budget impact. The base-case ICER and ICUR associated with hydrophilic coated catheters were €20 761 and €24 405, respectively. This implies that hydrophilic coated catheters are likely to be cost-effective in comparison to uncoated ones, as proposed Italian threshold values range between €25 000 and €66 400. Considering a market share at year 5 of 89% hydrophilic catheters and 11% uncoated catheters, the additional cost for Italy is approximately €12 million in the next 5 years (current market share scenario for year 0: 80% hydrophilic catheters and 20% uncoated catheters). Considered over a lifetime, hydrophilic coated catheters are potentially a cost-effective choice in comparison to uncoated ones. These findings can assist policymakers in evaluating intermittent

    To evaluate the accuracy of epidural catheter placement at different levels of the spinal cord guided solely by electrical nerve stimulation and resultant segmental muscle contraction. Prospective, experiment. Six male and two female Beagles, age (1 ± 0.17 years) and weight (12.9 ± 1.1 kg). Animals were anesthetized with propofol and maintained with isoflurane. An insulated epidural needle was used to reach the lumbosacral epidural space. A Tsui epidural catheter was inserted and connected to a nerve stimulator (1.0 mA, 0.1 ms, 2 Hz) to assess positioning of the tip at specific spinal cord segments. The catheter was advanced to three different levels of the spinal cord: lumbar (L2-L5), thoracic (T5-T10) and cervical (C4-C6). Subcutaneous needles were previously placed at these spinal levels and the catheter was advanced to match the needle location, guided only by corresponding muscle contractions. Catheter position was verified by fluoroscopy. If catheter tip and needle were at the same vertebral body a score of zero was assigned. When catheter tip was cranial or caudal to the needle, positive or negative numbers, respectively, corresponding to the number of vertebrae between them, were assigned. The mean and standard deviation of the number of vertebrae between catheter tip and needle were calculated to assess accuracy. Results are given as mean ± SD. The catheter position in relation to the needle was within 0.3 ± 2.0 vertebral bodies. Positive predictive values (PPV) were 57%, 83% and 71% for lumbar, thoracic and cervical regions respectively. Overall PPV was 70%. No significant difference in PPV among regions was found. Placement of an epidural catheter at specific spinal levels using electrical nerve stimulation was feasible without radiographic assistance in dogs. Two vertebral bodies difference from the target site may be clinically acceptable when performing segmental epidural regional anesthesia. © 2013 Association of Veterinary
