Pulmonary infarction, pleural effusion in [keywords]
- Incidence, outcome, and attributable resource use associated with pulmonary and cardiac complications after major small and large bowel procedures. [Journal Article]
- Perioper Med (Lond) 2014.:7.
Complications increase the costs of care of surgical patients. We studied the Premier database to determine the incidence and direct medical costs related to pulmonary complications and compared it to cardiac complications in the same cohort.We identified 45,969 discharges in patients undergoing major bowel procedures. Postoperative pulmonary and cardiac complications were identified through the use of International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) codes and through the use of daily resource use data. Pulmonary complications included pneumonia, tracheobronchitis, pleural effusion, pulmonary failure, and mechanical ventilation more than 48 h after surgery. Cardiac complications included ventricular fibrillation, acute myocardial infarction, cardiogenic shock, cardiopulmonary arrest, transient ischemia, premature ventricular contraction, and acute congestive heart failure.Postoperative pulmonary complications (PPC) or postoperative cardiac complications (PCC) were present in 22% of cases; PPC alone was most common (19.0%), followed by PPC and PCC (1.8%) and PCC alone (1.2%). The incremental cost of PPC is large ($25,498). In comparison, PCC alone only added $7,307 to the total cost.The current study demonstrates that postoperative pulmonary complications represent a significant source of morbidity and incremental cost after major small intestinal and colon surgery and have greater incidence and costs than cardiac complications alone. Therefore, strategies to reduce the incidence of these complications should be targeted as means of improving health and bending the cost curve in health care.
- [Drug induced eosinophilic pleural effusion]. [English Abstract, Journal Article]
- Pneumologia 2014 Apr-Jun; 63(2):118-21.
The hypersensitivity reactions induced by drugs, some widely used, like central nervous system medication, can have various presentations. The lung is a frequent target for such events. We present the case of 40-year-old male patient, non-smoker, with infant encephalopaty, seizures since age of 6 with polimorphic crisis (mainly absences), with anticonvulsivant treatment since 2011 (carbamazepine, sodium valproate, levetiracetam), with no respiratory medical history. Current symptoms started two weeks before, with chest pain, dry cough. He received no antibiotics. Chest X-ray and thoracic CT scan (27 June 2013) showed a left pleral effusion. Left exploratory thoracocentesis extracted 20 ml reddish pleural fluid: eosinophilic exsudate (60%) with normal adenosin deaminase. He also presents moderate blood eosinophilia (13.7%-1780/mm3). Pulmonary infarction with secondary pleurisy, thoracic trauma, acute pancreatitis with secondary pleurisy were excluded. No Loeffler transient infiltrates were documented, serology for Toxocara is IgG positive (historical) and not significant for current episode, no symptoms suggestive for toxocarosis (characteristic to young children, patient had no liver enlargement etc.), no hidatidosis or trichinelosis were found. As an exclusion diagnosis, a hypersensitivity reaction to anticonvulsivant medication was considered (mentioned in literature) carbamazepine and sodium valproate (even if medication was taken for a longer time), with blood and pleural eosinophilia. Together with the neurologist, the mentioned drugs were stopped and he was started on lamotrigine 2 tb/day and levetiracetam 1 tb/day, well tolerated, no absences were noticed. Total remission of blood eosinophilia and partial remission of pleural effusion were noticed. Subsequent follow-ups confirm favourable evolution, with healing of pleurisy and normal blood cell count, which are stable at 7 months after changing anticonvulsivant treatment.
- Dilated cardiomyopathy in a De Brazza's monkey (Cercopithecus neglectus). [Journal Article]
- J Med Primatol 2014 Jun; 43(3):209-12.
Cardiomyopathies have been reported in many primates. They may result from an inflammatory response to an infectious agent, nutritional deficiency, familial-genetic inheritance or toxic agents, but in many cases they are idiopathic.A De Brazza's monkey (Cercopithecus neglectus) presented with weight loss and inappetence. Physical examination, blood collection and diagnostic imaging and an electrocardiogram were performed.Radiographs and echocardiogram revealed pleural effusion with partially collapsed lungs, cardiomegaly, and reduced myocardial contractility from myocardial failure.Necropsy revealed pulmonary infarction, subsequent to heart failure from dilated cardiomyopathy.
- Middle cerebral artery infarction in a cancer patient: a fatal case of Trousseau's syndrome. [Journal Article]
- Hong Kong Med J 2014 Feb; 20(1):74-7.
Trousseau's syndrome is defined as any unexplained thrombotic event that precedes the diagnosis of an occult visceral malignancy or appears concomitantly with a tumour. This report describes a young, previously healthy man diagnosed to have an acute middle cerebral arterial ischaemic stroke and lower-limb deep vein thrombosis, who subsequently succumbed to pulmonary arterial embolism. During the course of his illness, he was diagnosed to have a malignant pleural effusion secondary to an occult adenocarcinoma. This report highlights the need for a high degree of suspicion for occult malignancy and non-bacterial thrombotic endocarditis in young (<60 years old) ischaemic stroke patients with no identifiable conventional cardiovascular risks. In selected patients, transoesophageal echocardiography is the diagnostic investigation of choice, since transthoracic imaging is not sensitive. Screening tests for serum tumour markers and prompt heparinisation of these patients are suggested whenever ischaemic stroke secondary to malignancy-induced systemic hypercoagulability is suspected.
- Patient, treatment and discharge factors associated with hospital readmission within 30 days after surgical cytoreduction for epithelial ovarian carcinoma. [Journal Article]
- Gynecol Oncol 2013 Sep; 130(3):407-10.
Hospital readmissions are common, costly and increasingly viewed as adverse events. In gynecologic oncology, data on readmissions are limited. The goal of this study was to examine the patient, treatment and discharge factors associated with unplanned readmission after cytoreductive surgery.We identified all patients with stages II-IV ovarian cancer who underwent surgical cytoreduction at our institution between 2003 and 2011. A retrospective chart review was performed, and clinical variables were extracted. Utilizing linear and logistic regression, these clinical variables were correlated with risk of readmission.A total of 460 patients were included in the analysis, with the majority having a stage IIIC high grade serous cancer. Optimal cytoreduction (<1.0 cm residual disease) was obtained in 368 patients (81%), and 233 patients (50%) underwent at least one radical procedure. Perioperative complications were observed in 148 patients (32%). A large proportion of our cohort was discharged to rehabilitation facilities (12%) or with a visiting nurse (38%). Fifty five patients (12%) were readmitted within 30 days. On multivariate logistic regression, reoperation and perioperative cardiopulmonary event were the only factors associated with readmission (OR=3.2, 95% CI=1.7-6.0). Discharge home with ancillary services was not protective against readmission, even when controlling for perioperative complications (OR=1.18, 95% CI=0.53-2.64).Readmission after surgical cytoreduction affected 12% of our population. Multivariate analyses suggested perioperative complications, particularly reoperation and cardiopulmonary event, placed the patient at the greatest risk. Age, comorbidities, surgical radicality and discharge with visiting nurse services/rehabilitation facility did not affect the likelihood of readmission.

- Short-term effectiveness of radiochemoembolization for selected hepatic metastases with a combination protocol. [Journal Article]
- World J Gastroenterol 2012 Oct 7; 18(37):5249-59.
To introduce the combination method of radiochemoembolization for the treatment of selected hepatic metastases.Twenty patients with biopsy proven hepatic metastases were selected from those who underwent transarterial radiochemoembolization, a novel combination protocol, between January 2009 and July 2010. Patients had different sources of liver metastasis. The treatment included transarterial administration of three chemotherapeutic drugs (mitomycin, doxorubicin and cisplatin), followed by embolization with large (50-150 μm) radioisotope particles of chromic 32P. Multiphasic computer tomography or computer tomography studies, with and without contrast medium injections, were performed for all patients for a short-term period before and after the treatment sessions. The short-term effectiveness of this procedure was evaluated by modified response evaluation criteria in solid tumors (mRECIST), which also takes necrosis into account. The subjective percentage of necrosis was also assessed. The response evaluation methods were based on the changes in size, number, and the enhancement patterns of the lesions between the pre- and post-treatment imaging studies.Patients had liver metastasis from colorectal carcinomas, breast cancer, lung cancer and carcinoid tumors. The response rate based on the mRECIST criteria was 5% for complete response, 60% for partial response, 10% for stable disease, and 25% for progressive disease. Regarding the subjective necrosis percentage, 5% of patients had complete response, 50% had partial response, 25% had stable disease, and 20% had progressive disease. Based on traditional RECIST criteria, 3 patients (15%) had partial response, 13 patients (65%) had stable disease, and 4 patients (20%) had disease progression. In most patients, colorectal carcinoma was the source of metastasis (13 patients). Based on the mRECIST criteria, 8 out of these 13 patients had partial responses, while one remained stable, and 5 showed progressive disease. We also had 5 cases of breast cancer metastasis which mostly remained stable (4 cases), with only one partial response after the procedure. Six patients had bilobar involvement; three of them received two courses of radiochemoembolization. The follow up imaging study of these patients was performed after the second session. In the studied patients there was no evidence of extrahepatic occurrence, including pulmonary radioactive deposition, which was proven by Bremsstrahlung scintigraphy performed after the treatment sessions. For the short-term follow-ups for the 2 mo after the therapy, no treatment related death was reported. The mostly common side effect was post-embolization syndrome, presented as vomiting, abdominal pain, and fever. Nineteen (95%) patients experienced this syndrome in different severities. Two patient had ascites (with pleural effusion in one patient) not related to hepatic failure. Moreover, no cases of acute liver failure, hepatic infarction, hepatic abscess, biliary necrosis, tumor rupture, surgical cholecystitis, or non-targeted gut embolization were reported. Systemic toxicities such as alopecia, marrow suppression, renal toxicity, or cardiac failure did not occur in our study group.Radiochemoembolization is safe and effective for selected hepatic metastases in a short-term follow-up. Further studies are required to show the long-term effects and possible complications of this approach.
- [Bilaterale pneumonia after myocardial infarction]. [Case Reports, English Abstract, Journal Article]
- Praxis (Bern 1994) 2012 Aug 8; 101(16):1045-9.
A 63-year-old man was admitted with fever and bilateral pulmonary infiltrates accompanied by pleural effusion a few days after ST-segment elevation myocardial infarction treated with primary angioplasty and stent implantation. The diagnosis of early postmyocardial infarction syndrome (Dressler's syndrome) with pulmonary infiltrates was made after ruling out possible differential diagnosis such as pneumonia and congestive heart failure. Infiltrates and markers of inflammation resolved rapidly with systemic steroid therapy. Etiology, diagnosis and treatment of this immunological reaction with inflammation of pericardium, pleura and often pulmonary parenchyma are discussed.
- Increased emergency department computed tomography use for common chest symptoms without clear patient benefits. [Journal Article]
- J Am Board Fam Med 2012 Jan-Feb; 25(1):33-41.
The aim of this study was to examine changes in the utilization of computed tomography (CT) in the evaluation of common chest symptoms and the rate of clinically significant diagnoses in emergency departments after 2004.This study analyzed the National Hospital Ambulatory Medical Care Survey, comparing 1997 to 1999 and 2005 to 2007. Set in US emergency departments, individuals older than 14 years old were eligible. The main outcome was proportion of common chest symptom-related visits (n = 17,098) associated with a CT order before 2000 and after 2004. Secondary outcomes were the proportion of these visits associated with a clinically significant diagnosis (pulmonary embolism, acute myocardial infarction, acute coronary syndrome, heart failure, pneumonia, and pleural effusion); an incidental diagnosis such as lung mass; and a clinically nonsignificant diagnosis such as nonspecific chest pain.The proportion of common chest symptom-related visits associated with a CT order increased from 2.1% in 1997 to 1999 to 11.5% in 2005 to 2007 (P < .001), whereas the overall proportion of these visits associated with a clinically significant diagnosis decreased from 23.6% in 1997 to 1999 to 19.1% in 2005 to 2007 (P < .001).The rate of acute myocardial infarction diagnosis decreased from 6.6% to 3.3% (P < .001), whereas the rate of pulmonary embolism diagnosis did not change (0.33% vs. 0.47%; P = .24) from 1997 to 1999 to 2005 to 2007. The rate of incidental diagnoses did not change (0.13% vs. 0.17%; P = .69), whereas the rate of clinically nonsignificant diagnoses increased from 35.6% to 45.8% (P < .001) from 1997 to 1999 to 2005 to 2007.CT ordering in emergency departments for the evaluation of common chest symptoms has increased dramatically without improving the rate of pulmonary embolism or other clinically significant diagnoses. Overuse of CT exposes patients to radiation and increases health care costs without any apparent diagnostic benefit.
- [A case of clopidogrel-induced eosinophilic pneumonia]. [Case Reports, English Abstract, Journal Article]
- Nihon Kokyuki Gakkai Zasshi 2011 Nov; 49(11):838-42.
An 83-year-old man had been prescribed clopidogrel for pontine infarction since 8 months previously, and had had a cough for the last 2 weeks of this period. Laboratory examinations on admission showed a marked increase in eosinophils and elevated serum immunoglobulin E levels. Chest radiography showed bilateral ground-glass opacities, mild reticulation, and interlobar pleural effusion in the minor fissure. After clopidogrel was discontinued his symptoms resolved, and his laboratory tests showed normal results. Bronchoalveolar lavage also showed an increase in eosinophils, and transbronchial biopsy revealed infiltration of eosinophils in the subepithelium of the bronchial mucosa. On the basis of these findings, we diagnosed eosinophilic pneumonia induced by clopidogrel. Reports on cases of lung diseases caused by anti-platelet drugs are rare. To the best of our knowledge, this case is the first report on clopidogrel-induced eosinophilic pneumonia.
