    Summary Background To evaluate the safety, etiology and outcomes of patients undergoing bilateral thoracentesis. Methods This is a prospective cohort study of 100 consecutive patients who underwent bilateral thoracenteses in an academic medical center from July 2009 through November 2010. Pleural fluid characteristics and etiologies of the effusions were assessed. Mean differences in levels of fluid characteristics between right and left lungs were tested. Associations between fluid characteristics and occurrence of bilateral malignant effusions were evaluated. The rate of pneumothorax and other complications subsequent to bilateral thoracentesis was determined. Results Exudates were more common than transudates, and most effusions had multiple etiologies, with 83% having two or more etiologies. Bilateral malignant effusions occurred in 19 patients, were the most common single etiology of exudative effusions, and were associated with higher levels of protein and LDH in the pleural fluid. Among 200 thoracenteses performed with a bilateral procedure, seven resulted in pneumothoraces, three of which required chest tube drainage and four were ex vacuo. Conclusions More often than not, there are multiple etiologies that contribute to pleural fluid formation, and of the combinations of etiologies observed congestive heart failure was the most frequent contributor. Exudative effusions are more common than transudates when bilateral effusions are present. Malignancy is a common etiology of exudative effusions. This study suggests that the overall complication rate following bilateral thoracentesis is low and the rate of pneumothorax subsequent to bilateral thoracentesis is comparable to unilateral thoracentesis.

    Presentation of pericardial disease is diverse, with the viral aetiology being the most common cause; however, when haemorrhagic pericardial effusion is present, these causes are narrowed to few aetiologies. We present a case of a young female of African descent who presented with diffuse abdominal pain and vomiting. Initial work-up showed pericardial effusion with impending echocardiographic findings of cardiac tamponade and bilateral pleural effusions. Procedures included a left video-assisted thoracoscopic surgery (VATS) with pericardial window. We consider that it is important for all physicians to be aware of not only typical presentation but also atypical and unusual clinical picture of pericardial disease. PMID:27807484

    Laryngocele is an uncommon condition that represents a benign dilatation of the laryngeal saccule with air and/or fluid, arising in the region of the laryngeal ventricle. Laryngoceles, or laryngomucocele can be classified as internal, or combined. The aim of presenting this rare case of a bilateral combined laryngocele, are to emphasize the importance of diagnostic laryngoscopy in upper airway pathologies evaluation, increase awareness in the general otolaryngologist community, and to highlight the external surgical method.

    In the absence of firm recommendations, we analyzed whether unilateral thoracic puncture is sufficient for bilateral pleural effusion (PE), or if the procedure needs to be performed in both sides. Prospective study of patients seen consecutively for bilateral PE during a period of 3 years and 9 months. All patients underwent simultaneous bilateral thoracocentesis. The standard protocol variables collected in our hospital served as study parameters. Size of PE, presence of chest pain or fever, or accompanying lung abnormalities, different attenuation values on chest computed tomography, presence of loculated pleural fluid, and radiological resolution in a single side were also evaluated. A total of 36 patients (19 men; mean age 68.5 ± 16.5 years) were included. The etiology of the effusion was different in each side in only 2 patients (5.6%). In 6/32 cases (18.8%), the biological analysis of the pleural fluid (in terms of transudate/exudate) from both sides did not correspond with the etiological diagnosis of the effusion. Correlation between biochemical parameters analyzed in the fluid from both sides (Pearson's correlation coefficient) ranged between 0.74 (LDH) and 0.998 (NT-proBNP). As different diagnoses in each side were found in only 2 patients, the circumstances in which bilateral diagnostic thoracocentesis would be necessary could not be determined. Simultaneous bilateral thoracocentesis does not appear to be recommendable. Larger series are needed to establish which factors might suggest the need for simultaneous puncture of both PE.

    Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by sicca symptoms. Interstitial pulmonary fibrosis and tracheobronchial sicca are the most common symptoms of pulmonary involvement in primary SjS, and they are rarely accompanied by serositis such as pleuritis or pericarditis. We report a case of SS presenting initially with bilateral pleural effusions. A 63-year old man was admitted to our hospital with a one-month history of cough, dyspnea, and right chest pain. Chest-computed tomography revealed bilateral pleural effusions. Serum anti-SS-A antibody titer was 1 : 256. Ophthalmological examination revealed a positive Schirmer test. Lip biopsy showed atrophy and plasmacytic infiltration of the salivary gland. Corticosteroid treatment was initiated. Pleural effusions were almost completely resolved by day 30. The patient has not experienced any recurrence. PMID:23198246

    A 70-year-old woman was admitted to our hospital with pleuritis and pericarditis. Cytological examination of pleural and pericardial effusion, and pleural biopsy specimens under thoracoscopy revealed no specific pathological findings. The pleural effusion was drained continuously; however, she died of circulatory insufficiency at day 45 from admission. At autopsy, a fragile hemorrhagic mass arising from the right auricle had invaded bilateral pleura and the pericardium directly without distant metastasis. Immunohistochemical staining showed that the tumor cells expressed endothelial markers such as CD31 and CD34 antibodies, and factor VIII-related protein. These findings supported the diagnosis of a poorly differentiated angiosarcoma.

    Rhupus syndrome is a rare syndrome characterized by overlap of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Our patient was a diagnosed case of RA and developed SLE 2 years after. She was a middle-aged woman, presented with bilateral pleural effusion with exacerbation of skin and joint symptoms of SLE. We diagnosed the case as tubercular pleural effusion by positive Mycobacterium tuberculosis in bactec 460 culture. She had also anti-phospholipid antibody positivity without any symptoms and signs of thrombosis.

    Pleural involvement in sarcoidosis is uncommon and appears in several forms. To document the incidence and characteristics of pleural effusion in sarcoidosis patients, a review of the cases diagnosed in our centre between January 2001 and December 2012 was carried out. One hundred and ninety-five patients with sarcoidosis were identified; three (two men and one woman) presented with unilateral pleural effusion (1.5%): one in the right side and two in the left. Two were in stageii and one was in stageiv. The pleural fluid of the two patients who underwent thoracocentesis was predominantly lymphocytic. One of these patients presented chylothorax and the other had high CA-125levels. In general, these effusions are lymphocyte-rich, paucicellular, serous exudates (sometimes chylothorax) and contain proportionally higher levels of protein than LDH. Most cases are treated with corticosteroids, although it may resolve spontaneously.

    Remitting seronegative symmetrical synovitis with pitting edema syndrome is characterized by symmetrical synovitis with pitting edema in the dorsum of the hands or feet. Most cases of remitting seronegative symmetrical synovitis with pitting edema syndrome are idiopathic, but some are secondary to malignancy, autoimmune disease, or neurodegenerative disorders. Pleural and pericardial effusions are unusual complications in idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome. A 74-year-old Japanese woman presented to our hospital with arthralgia and pitting edema in her feet. She had pain in multiple joints, peripheral edema, and a markedly elevated erythrocyte sedimentation rate. Enhanced computed tomography and laboratory data showed no evidence of malignancy. These findings suggested that she had idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome. She also developed respiratory distress because of bilateral pleural and pericardial effusions. Laboratory data showed that serum vascular endothelial growth factor and interleukin-6 were significantly elevated. After administration of steroids, her pleural and pericardial effusions decreased and finally disappeared. Furthermore, vascular endothelial growth factor and interleukin-6 decreased when the pleural and pericardial effusions disappeared. Here we report the case of a patient with idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome associated with life-threatening complications, including bilateral pleural and pericardial effusions during the course of the illness, which led to respiratory failure and atrial fibrillation. Elevated vascular endothelial growth factor and interleukin-6 may be associated with the cause of pleural and pericardial effusions in idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome.

    To best of our knowledge, this is the first reported case of pericardial and pleural effusions combined with ascites, precipitated with severe sunitinib-induced hypothyroidism. A 58-year-old man presented in our emergency department due to dyspnoea and dry cough. Sixteen months earlier, the patient underwent left nephrectomy due to metastatic renal cell adenocarcinoma (RCC), and therapy with sunitinib was initiated postoperatively. Thyroid function was not assessed during the therapy. On admission, all laboratory findings were within normal range. Computed tomography of the chest detected voluminous bilateral pleural effusions and mild pericardial effusion, and echocardiography revealed pericardial effusion. Thoracocentesis was carried out three times, and cytological examination showed no signs of malignant cells. After assessment of the thyroid function, neglected hypothyroidism was registered. Substitution therapy with levothyroxine was initiated, and thyroid function normalised 2 weeks later. Few days after the last thoracocentesis, his condition suddenly got worse. Thoracocentesis was repeated, and microbiological analysis of the exudate came positive for Klebsiella pneumoniae and Streptococcus pneumoniae. Despite the implemented therapeutic measures, his clinical condition progressively deteriorated. The patient died 27 days after the admission, hospital-acquired pneumonia was identified as the cause of death. Our case emphasises the necessity of careful monitoring and management of side-effects in patients who receive sunitinib. Hypothyroidism is a known cause of pleural, pericardial and abdominal effusions, as reported in several case reports. Timely initiation of substitution levothyroxine therapy can decrease unnecessary pauses in the therapy with sunitinib, as well as prevent development of severe symptoms.

    A 28-year-old man had a 1-year history of hemoptysis. Consequently, he underwent a medical examination. A right pleural effusion, left hydropneumothorax, and multiple pulmonary nodular shadows were found on chest radiography. During a detailed interview, he reported that the hemoptysis began after eating "kejang" (a raw crab preparation) with a friend a year previously. His peripheral blood eosinophil count and serum IgE level were elevated. In addition, ova were detected in the sputum and bilateral pleural effusion. Morphological examination of the ova and immunoserological examination led to the diagnosis of Paragonimus westermani infection. The pleural effusion could be partially drained, and his symptoms and radiographic results showed improvement after treatment with Praziquantel administered at a dose of 75 mg/(kg x day) for 3 days. After one month, he and his friend ate seasoned raw crabs, Paragonimus was diagnosed in his friend. This case suggests that on encountering a paragonimus infection, everyone who ate food prepared in the same kitchen should be contacted because of possible infection with paragonimus.

    Background The surgical insertion of Ventilation Tubes (VTs) for the management of persistent bilateral Otitis Media with Effusion (OME) in children remains a contentious issue due to the varying opinions regarding the risks and benefits of this procedure. The aim of this study was to evaluate the economic impact of VTs insertion for the management of persistent bilateral OME in children, providing an additional perspective on the management of one of the commonest medical conditions of childhood. Methods A decision-tree model was constructed to assess the cost-effectiveness of VTs strategy compared with the Hearing Aids (HAs) alone and HAs plus VTs strategies. The model used data from published sources, and assumed a 2-year time horizon and UK NHS perspective for costs. Outcomes were computed as Quality-Adjusted Life-Years (QALYs) by attaching a utility value to the total potential gains in Hearing Level in decibels (dBHL) over 12 and 24 months. Modelling uncertainty in the specification of decision-tree probabilities and QALYs was performed through Monte Carlo simulation. Expected Value of Perfect Information (EVPI) and partial EVPI (EVPPI) analyses were conducted to estimate the potential value of future research and uncertainty associated with the key parameters. Results The VTs strategy was more effective and less costly when compared with the HAs plus VTs strategy, while the incremental cost-effectiveness ratio for the VTs strategy compared with the HAs strategy was £5,086 per QALY gained. At the willingness-to-pay threshold of £20,000 per QALY, the probability that the VTs strategy is likely to be more cost-effective was 0.58. The EVPI value at population level of around £9.5 million at the willingness-to-pay threshold of £20,000 indicated that future research in this area is potentially worthwhile, while the EVPPI analysis indicated considerable uncertainty surrounding the parameters used for computing the QALYs for which more precise estimates would be

    Otitis media with effusion (OME) is the most common cause of acquired hearing loss in childhood and has been associated with delayed language development and behavioral problems. In this study, children with an evidently recurrent otitis media were investigated. The present study examines the association between hearing loss versus developmental screening test parameters of preschool children. Sixteen children with bilateral otitis media were compared with age-matched same number of children with normal hearing (controls). Language and verbal cognitive abilities were not affected significantly as a result of the presence of hearing loss because of OME. Using internationally standardized Denver-II test to evaluate the language development and other developmental screening parameters, no significant difference was found between the patient and control groups. This study failed to find any association between the hearing loss due to otitis media with effusion and speech and language parameters in preschool children.

    The aim of the present study was to evaluate the diagnostic value of the tumour markers carcinoembryonic antigen (CEA), carbohydrate antigens CA 125, CA 15.3, CA 19.9 and tumor-associated glycoprotein 72 (TAG 72) in the pleural fluid (PF) of patients with pleural effusions of different etiologies. One hundred and fifty-five patients with pleural effusions (40 malignant, 84 benign and 31 paraneoplastic) were studied prospectively. The concentration of the tumour markers in serum and PF were measured by magnetic particle enzyme immunoassay. The PF to serum (PF/S) concentration ratios were calculated. The concentrations of CEA, CA 15.3, CA 19.9 and TAG 72 in PF and the PF/serum ratios were significantly higher in effusions of malignant and paraneoplastic origin than in those of benign origin. The receiver operating characteristic (ROC) curves were calculated for each marker and the diagnostic cut-off point was selected as the value that offered a specificity of 100% (CEA: 6.5 ng/ml; CA 15.3:62.4 IU/l; TAG 72:10.9 IU/l). CEA presented the greatest sensitivity [45% in the malignant group, 38.7% in the paraneoplastic group, and 41.4% in the pooled group (combined malignant and paraneoplastic)]. TAG 72 presented the largest area under the curve (0.89 in the malignant group and 0.80 in the pooled group). The diagnostic efficacy of the PF/S ratios was not better than measurement of the tumour markers in pleural fluid. The highest diagnostic accuracy for the diagnosis of malignant pleural effusions was achieved by grouping the markers in a panel comprising CEA, CA 15.3 and TAG 72; this showed a sensitivity of 75% and a negative predictive value of 79.1% . In the subgroup of patients with negative cytology, the sensitivity was 41.2% for CEA, 35.5% for CA 15.3 and 33.3% for TAG 72. The combination of these three markers achieved a sensitivity of 84.6%. The combined measurement of CEA, CA 15.3 and TAG 72 in pleural fluid is a useful complementary test in the differential

    2012-04-01

    To determine the adjuvant effects of adenoidectomy with short-stay ventilation tubes to hearing and revision surgery in children over 3.5 years with persistent otitis media with effusion. Randomised controlled three armed trial: observation, short-stay ventilation tube or ventilation tubes with adjuvant adenoidectomy. Five follow-up visits over 2 years. Eleven UK Otorhinolaryngology Departments. Children with bilateral otitis media with effusion and better ear hearing level (HL) ≥20 dB persistent for 3 months. Of the 425 eligible children, 376 (88%) accepted randomisation. Pure-tone hearing thresholds, eligibility for and actual revision surgery rates, otoscopic sequelae and complications of adenoidectomy. Loss to follow-up at 3, 12 and 24 months was 2%, 6% and 5% respectively. Of the 376 randomised children, 253 (67%) had complete data for all five follow-up visits. Adenoidectomy did not add to the benefit to hearing thresholds of ventilation tubes of 8.8 dB (CI: 7.1-10.5) averaged over 3-6 months postoperatively. Averaged over 12, 18 and 24 months, adenoidectomy provided 4.2 dB of benefit (CI: 2.6-5.7) whilst ventilation tubes gave no benefit. Standardised effect sizes through two years showed equal benefit from ventilation tubes (0.50 sd) and adenoidectomy (0.61 sd) which are additive (1.11 sd). Adenoidectomy halved the numbers meeting a 25 dB HL bilateral cut-off for eligibility for repeat tube surgery from 31% to 14% at 12 months and from 33% to 15% at 18 months. The actual reduction in re-insertion surgery (absolute risk difference) was 21%. In tubed ears, tympanosclerosis occurred in 27%, but otorrhoea in only <2% and permanent perforations in <1%. These events did not occur in control ears. In children that had adenoidectomy, one of 165 (0.6%) had haemorrhage that required return to theatre. Adjuvant adenoidectomy doubles benefit from short-stay ventilation tubes by extending better hearing through the second year in children aged 3.25-6.75 years with

    Purpose. To report a case of bilateral Coats' disease combined with retinopathy of prematurity (ROP). Case. Retinal vascularization was complete in the right eye, whereas zone III, stage 3 ROP and preplus disease were observed in the left eye at 43 weeks of postmenstrual age (PMA) in a 31-week premature, 1200-g neonate. Intraretinal exudates developed and retinal hemorrhages increased in the left eye at 51 weeks of PMA. Diode laser photocoagulation (LP) was applied to the left eye. Exudates involved the macula, and telangiectatic changes developed one month following LP. Additional LP was applied to the left eye combined with intravitreal bevacizumab (IVB) injection at 55 weeks of PMA. Disease regressed one month after the additional therapy. At the 14-month examination of the baby, telangiectatic changes and intraretinal exudates were observed in the right eye. Diode LP was applied to the right eye combined with IVB injection. Exudates did not resolve completely, and cryotherapy was applied one month following LP. Retinal findings regressed three months following the cryotherapy. Conclusion. This is the first report of presumed bilateral Coats' disease combined with ROP. If Coats' disease could be diagnosed at early stages, it would be a disease associated with better prognosis.

    The usefulness of clinical, radiological and pleural fluid analytical parameters for diagnosing malignant and paramalignant pleural effusion is not clearly stated. Hence this study aimed to identify possible predictor variables of diagnosing malignancy in pleural effusion of unknown aetiology. Clinical, radiological and pleural fluid analytical parameters were obtained from consecutive patients who had suffered pleural effusion of unknown aetiology. They were classified into three groups according to their final diagnosis: malignant, paramalignant and benign pleural effusion. The CHAID (Chi-square automatic interaction detector) methodology was used to estimate the implication of the clinical, radiological and analytical variables in daily practice through decision trees. Of 71 patients, malignant (n = 31), paramalignant (n = 15) and benign (n = 25), smoking habit, dyspnoea, weight loss, radiological characteristics (mass, node, adenopathies and pleural thickening) and pleural fluid analytical parameters (pH and glucose) distinguished malignant and paramalignant pleural effusions (all with a p < 0.05). Decision tree 1 classified 77.8% of malignant and paramalignant pleural effusions in step 2. Decision tree 2 classified 83.3% of malignant pleural effusions in step 2, 73.3% of paramalignant pleural effusions and 91.7% of benign ones. The data herein suggest that the identified predictor values applied to tree diagrams, which required no extraordinary measures, have a higher rate of correct identification of malignant, paramalignant and benign effusions when compared to techniques available today and proved most useful for usual clinical practice. Future studies are still needed to further improve the classification of patients.

    Primary effusion lymphoma (PEL) is a rare form of aggressive B cell lymphoma caused by Kaposi's sarcoma-associated herpesvirus (KSHV). Current chemotherapy approaches result in dismal outcomes, and there is an urgent need for new PEL therapies. Previously, we established, in a direct xenograft model of PEL-bearing immune-compromised mice, that treatment with the proteasome inhibitor, bortezomib (Btz), increased survival relative to that after treatment with doxorubicin. Herein, we demonstrate that the combination of Btz with the histone deacetylase (HDAC) inhibitor suberoylanilidehydroxamic acid (SAHA, also known as vorinostat) potently reactivates KSHV lytic replication and induces PEL cell death, resulting in significantly prolonged survival of PEL-bearing mice. Importantly, Btz blocked KSHV late lytic gene expression, terminally inhibiting the full lytic cascade and production of infectious virus in vivo. Btz treatment led to caspase activation and induced DNA damage, as evidenced by the accumulation of phosphorylated γH2AX and p53. The addition of SAHA to Btz treatment was synergistic, as SAHA induced early acetylation of p53 and reduced interaction with its negative regulator MDM2, augmenting the effects of Btz. The eradication of KSHV-infected PEL cells without increased viremia in mice provides a strong rationale for using the proteasome/HDAC inhibitor combination therapy in PEL.

    Malignant pericardial effusion is one of the serious complications of lung cancer and lack effective treatment methods. The aim of this study is to evaluate the efficacy and safety of radiofrequency hyperthermia combined with chemotherapy for patients with malignant pericardial effusion caused by lung cancer. Fifty-five patients with malignant pericardial effusion caused by lung cancer were divided into hyperthermia combined with chemotherapy group (combined therapy group) and chemotherapy group. The combined therapy group was treated with radiofrequency hyperthermia after the pericardiocentesis and intracavitary injection (cisplatin 20 mg and dexamethasone 5 mg), when patients' general state of health improved, systemic chemotherapy was performed. The chemotherapy group was treated only with intracavitary injection and systemic chemotherapy. Intracavitary chemotherapy was performed for 1-6 times (average 3 times). Hyperthermia was performed twice per week with an average of 6 times following intracavitary and systemic chemotherapy. The temperature of intracavitary was 40.5 °C-41.5 °C for 60 min during the hyperthermia periods. Systemic chemotherapy consists of cisplatin (75 mg/m²) and vinorelbine (50 mg/m²). The complete remission rate (CR) of malignant pericardial effusion was 54.3% and the response rate (RR) was 91.4% in the combined therapy group, while the rates of CR and RR of chemotherapy group were 25.0% and 70.0%, and the differences of CR and RR between the two groups were significant (P<0.05). After treatment, the quality of life improved significantly in both groups, but the combined therapy group had a higher KPS score than in the chemotherapy group (P<0.05). The adverse events associated with the chemotherapy included gastrointestinal toxicity and myelosuppression, and there were no significant differences between the two groups. The main side effects associated with radiofrequency hyperthermia included local skin ache (8.6%) and induration of

  11. Pleural effusions in acute idiopathic pericarditis and postcardiac injury syndrome.

    2017-07-01

    Pleural effusions are frequent in the context of acute idiopathic pericarditis and following pericardiotomy, but they have seldom been characterized. This review summarizes their most relevant clinical features. In acute idiopathic pericarditis, pleural effusions tend to be left-sided and, if bilateral, they are usually larger on the left. Less than 5% are unilateral right-sided. About 90% of the effusions occupy less than one-third of the hemithorax, and 99% meet Light's exudative criteria with a predominance of lymphocytes in three fourths of the cases. Although postcardiac injury syndrome (PCIS)-related effusions share similar characteristics, they present some differential features: more than 15% are unilateral on the right (except for Dressler syndrome), one-fourth opacify half or more of the hemithorax, and nearly two thirds are bloody. The combination of nonsteroidal anti-inflammatory drugs and colchicine, along with therapeutic thoracenteses for moderate-to-large effusions, is the mainstay treatment approach. The postoperative use of colchicine is also a reasonable option for preventing PCIS in patients who have undergone cardiac surgery. Pleural effusions because of pericardial diseases remain a clinical diagnosis. If unilateral right-sided, massive, or transudative effusions are seen, an alternative diagnosis to acute pericarditis should be considered.

    Ischaemic optic neuropathy is a rare but serious complication post cardiopulmonary bypass in cardiac surgery patients. It presents with visual loss either unilaterally or bilaterally, and it can be anterior or posterior in type depending on the segment of the optic nerve involved. In non-ocular surgery patients, the most common type is called non-arteritic ischaemic optic neuropathy. We report a case of bilateral non-arteritic ischaemic optic neuropathy following coronary artery bypass grafting and mitral valve surgeries and review the published literature for the aetiology, management and prognosis of this rare complication. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Encephaloceles, while a common entity affecting 1:4000 live births, typically occur in the occipital region. Encephaloceles involving the frontal region comprise only 15% of all cases. Naso-orbital encephaloceles are rarely seen. Our case profiles a child born at term with an atrial septal defect (ASD), micrognathia, cleft lip, and frontonasal as well as bilateral naso-orbital encephaloceles. At birth the encephaloceles were undetected. During the cleft palate pre-operative preparation, the bilateral naso-orbital encephaloceles were diagnosed as dacrocystoceles for which the child underwent surgical repair. Misdiagnosis and loss to follow up lead to delayed surgical treatment until the child was almost two years of age; the right eye was near complete closure due to the increasing size of the encephalocele. This case highlights the importance of meticulous radiologic interpretation of midline nasal masses, as a correct diagnosis impacts clinical management and directs surgical repair. PMID:22470768

    Background To determine the effects of dendritic cells (DCs) and cytokine-induced killer (CIK) cells in patients with malignant pericardial effusion. Material/Methods All patients underwent pericardial puncture and indwelling catheter insertion. After pericardial drainage, the 16 patients in the treatment group received an infusion of 20 mL DCs and CIK cells (>1.0×1010 cells) and 500,000 U interleukin (IL)-2 for 3 successive days. The 15 control-group patients received 30 mg/m2 cisplatin and 500,000 U IL-2 for 3 successive days. The treatment effects were assessed using imaging data. Results The total efficiency and complete remission rates were higher in the treatment group than in the control group at 4 weeks (total efficiency: 87.50% vs. 73.33%; complete remission: 62.50% vs. 46.67%) and 3 months after the treatment (total efficiency: 81.25% vs. 66.67%; complete remission: 50.00% vs. 40.00%; P<0.05 for all). In both groups, the Karnofsky scores for quality of life improved after treatment. However, the curative effects were better in the treatment group than in the control group (P<0.05). The following adverse reactions occurred: fever, 6 treatment-group patients and 3 control-group patients; chest pain, 2 treatment-group patients and 7 control-group patients; gastrointestinal reactions, 1 treatment-group patient and 6 control-group patients; and bone marrow suppression, 1 treatment-group patient and 5 control-group patients. The between-group differences in adverse reactions were significant (P<0.05). Conclusions The combination of DCs and CIK cells effectively treated malignant pericardial effusion, produced few side effects, and improved the patients’ quality of life. PMID:27806024

    The differential diagnosis of tuberculous pleural effusion (TPE) and malignant pleural effusion (MPE) remains difficult despite the availability of numerous diagnostic tools. The current study aimed to evaluate the performance of the whole blood QuantiFERON-TB Gold In-Tube (QFT-GIT) assay and conventional laboratory biomarkers in differential diagnosis of TPE and MPE in high tuberculosis prevalence areas. A total of 117 patients with pleural effusions were recruited, including 91 with TPE and 26 with MPE. All of the patients were tested with QFT-GIT, and the conventional biomarkers in both blood and pleural effusion were detected. The level of antigen-stimulated QFT-GIT in the whole blood of TPE patients was significantly higher than that of MPE (2.89 vs 0.33 IU/mL, P<0.0001). The sensitivity and specificity of QFT-GIT for the diagnosis of TPE were 93.0% and 60.0%, respectively. Among the biomarkers in blood and pleural effusion, pleural adenosine deaminase (ADA) was the most prominent biomarker, with a cutoff value of 15.35 IU/L. The sensitivity and specificity for the diagnosis of TPE were 93.4% and 96.2%, respectively. The diagnostic classification tree from the combination of these two biomarkers was 97.8% sensitive and 92.3% specific. Ultimately, the combination of whole blood QFT-GIT with pleural ADA improved both the specificity and positive predictive value to 100%. Thus, QFT-GIT is not superior to pleural ADA in the differential diagnosis of TPE and MPE. Combined whole blood QFT-GIT and pleural ADA detection can improve the diagnosis of TPE.

    Otitis media with effusion (OME) is a common problem facing general practitioners, pediatricians and otolaryngologists. This article reviews the etiopathogenesis, epidemiology, presentation, natural history and management of OME. The literature was reviewed by using the PubMed search engine and entering a combination of terms including 'otitis media with effusion', 'epidemiology' and 'management'. Relevant articles were identified and examined for content. What is the take home message? While OME is a very common entity in the pediatric population, the majority of cases will resolve spontaneously. Surgery in the form of grommet insertion, with or without adenoidectomy is the most effective treatment in persistent symptomatic cases.

    Abstract The current study is conducted to investigate efficacy of the chemotherapy drug paclitaxel in combination with Avastin (Roche Diagnostics GmbH., Mannheim, Germany) (antiangiogenic agent) in treatment of malignant pleural effusions (MPEs). Twenty-four patients with non–small cell lung cancer were randomly assigned for 2 treatment approaches. Ten patients received paclitaxel (175 mg/m2) alone, and 14 patients took a combination therapy of paclitaxel and Avastin (5 mg/kg). Efficacy of the treatment approaches in the patients was validated with the change in the MPE volume. Pharmacokinetic (PK) profile and urinary excretion rate of paclitaxel were analyzed with serum vascular endothelial growth factor (VEGF) level, and adverse events were examined as well. The combination therapy reduced the MPE level with a successful rate of 29% and a survival rate of 25% over the single paclitaxel treatment in the study cohort (both P < 0.05). PKs for the combined treatment displayed a rapid distribution of the anticancer drug paclitaxel with an obvious increase in its elimination half-life in the pleural fluid (both P < 0.01). Mean residence time of paclitaxel increased in the presence of Avastin (P < 0.01). Serum VEGF levels significantly reduced in the Avastin-treated patients as compared to the paclitaxel-treated ones (P < 0.01). The urinary excretion rate was similar in the study cohort. Incidence of adverse events for the 2 treatment approaches was similar in the patients. Intervention of Avastin enhances potency of paclitaxel in treatment of MPEs with the increased survival rate of the patients through inhibiting VEGF production and prolonging time of ongoing interaction between the chemotherapy drug and the tumor tissues.

    Pleural effusion (PE) remains a significant challenge and public health problem, which needs novel noninvasive biomarkers for the precise diagnosis. The aim of this study was to further determine the clinical efficacy and diagnostic accuracy of a novel combination of calprotectin and CXCL12 for predicting malignancy in patients with exudative PE.Calprotectin and CXCL12 concentrations were measured in 95 individuals of exudative PE, with 39 malignant PE (MPE) and 56 benign PE (BPE). The accuracy of calprotectin and CXCL12 levels for discriminating MPE from BPE or tuberculous PE were evaluated using receiver-operating characteristic (ROC) curves. Univariate and multivariate logistic regression analyses were performed to test the association between calprotectin and CXCL12 levels and MPE.Calprotectin and CXCL12 levels of patients with MPE were significantly lower than that of BPE and tuberculous PE (P < 0.05). The area under the curve (AUC) of calprotectin and CXCL12 was 0.683 and 0.641 in MPE and BPE, and a combination of calprotectin ≤500.19 ng/mL and CXCL12 ≤6.11 ng/mL rendered a sensitivity and specificity of 48.72% and 78.57%, respectively. While in MPE and tuberculous PE, the AUC of calprotectin and CXCL12 was 0.696 and 0.690, and a combination of calprotectin ≤421.73 ng/mL and CXCL12 ≤3.71 ng/mL presented a sensitivity and specificity of 25.64% and 95.45%, respectively. Multivariate logistic regression demonstrated that both calprotectin and CXCL12 were independent predictors of MPE.Calprotectin and CXCL12 in pleural fluid are informative diagnostic biomarkers for predicting patients with MPE.

    Hippocrates was the first physician to describe in accuracy pleural effusion and pneumonia. To treat empyema thoracis he had introduced a combined method of tracheal intubation with a simultaneously thoracotomy. The surgical incision was used for the pus to be progressively drainaged. If the patient was too weak to eat, he had suggested for nutritional mixtures to be administered through an oral-gastric tube. Thus Hippocrates composed in his operating theatre, an icon similar to modern surgical operations.

    Too extensive resection of the inferior turbinates (ITs) during nasal surgery leads to a severely disturbed intranasal air conditioning. Data comparing nasal air conditioning before and after turbinoplasty in nasal surgery are still lacking. The aim of this study was to determine the early effect of bilateral turbinoplasty combined with septoplasty on intranasal heating and humidification. Twelve patients were included into this prospective study. In one-half of the patients a bilateral turbinoplasty of the IT during nasal surgery was performed, in the other half no surgery on the IT was performed. Intranasal air temperature and humidity were measured before and after surgery. A combined miniaturized thermocouple and a humidity sensor were used for simultaneous in vivo intranasal measurements. There were no statistically significant differences in temperature and humidity values between the two study groups before surgery (p > 0.05). In both groups, the postoperative temperature and humidity values were statistically significantly higher compared with the preoperative ones (p < 0.05). Regarding the two patient groups, the postoperative increase in temperature and humidity was even more pronounced in patients undergoing additional bilateral turbinoplasty. According to the results of this study, patients seemed to overall benefit from nasal surgery, with and without a preserving bilateral turbinoplasty, because intranasal air conditioning was improved after surgery. A carefully performed and conservative reduction of the IT in nasal surgery seems to even improve intranasal air conditioning.

    Tuberculous pleural effusion (TBPE) is the most common form of extrapulmonary tuberculosis (TB) in Spain, and is one of the most frequent causes of pleural effusion. Although the incidence has steadily declined (4.8 cases/100,000population in 2009), the percentage of TBPE remains steady with respect to the total number of TB cases (14.3%-19.3%). Almost two thirds are men, more than 60% are aged between 15-44years, and it is more common in patients with human immunodeficiency virus. The pathogenesis is usually a delayed hypersensitivity reaction. Symptoms vary depending on the population (more acute in young people and more prolonged in the elderly). The effusion is almost invariably a unilateral exudate (according to Light's criteria), more often on the right side, and the tuberculin test is negative in one third of cases. There are limitations in making a definitive diagnosis, so various pleural fluid biomarkers have been used for this. The combination of adenosine deaminase and lymphocyte percentage may be useful in this respect. Treatment is the same as for any TB. The addition of corticosteroids is not advisable, and chest drainage could help to improve symptoms more rapidly in large effusions.

    The aim of the study was to compare the effects of bilateral, unilateral, or combined bilateral and unilateral plyometric training (PT) on muscle power output, endurance, and balance performance adaptations in young soccer players. Four groups of young soccer players (age 11.4 ± 2.2 years) were divided into control group (CG; n = 14), bilateral group (BG; n = 12), unilateral group (UG; n = 16), and bilateral + unilateral group (B + UG; n = 12). Players were measured in unilateral and bilateral countermovement jump with arms, 5 multiple bounds test, 20-cm drop jump reactive strength index, maximal kicking velocity, sprint and agility test time, endurance, and balance performance. The PT was applied during 6 weeks, 2 sessions per week, for a total of 2,160 jumps. After intervention, all PT groups showed a statistically significant (p ≤ 0.05) change in all performance measures, with no statistically significant differences between treatments. Among the 21 performance measures, the B + UG showed a significantly (p ≤ 0.05) higher performance change in 13 of them vs. the CG, whereas the UG and BG showed only 6 and 3, respectively. The current study showed that bilateral, unilateral, and combined bilateral and unilateral PT ensured significant improvement in several muscular power and endurance performance measures in young soccer players. However, the combination of unilateral and bilateral drills seems more advantageous to induce superior performance improvements.

    Background Ocular manifestations of the dengue fever virus include bilateral panuveitis that can occur after the acute systemic infection has resolved. In most reported cases, the inflammation resolves with topical or systemic steroid therapy. We report a case of chronic, refractory bilateral panuveitis and uveitic glaucoma that began during the acute phase of the systemic infection and required treatment with oral steroids, multiple steroid-sparing agents, and surgical therapy for glaucoma. Findings A 22-year-old male with acute systemic dengue fever presented with bilateral pain and decreased vision. Clinical examination revealed bilateral panuveitis with elevated intraocular pressures. Management required oral steroids, mycophenolate mofetil, cyclosporine, and bilateral glaucoma valve implantation. Conclusion This case highlights the fact that dengue-associated panuveitis can begin in the acute stage of systemic infection and persist long after convalescence with progression to chronic bilateral panuveitis and uveitic glaucoma. Dengue-associated chronic panuveitis with uveitic glaucoma may be effectively managed with a combination of steroid-sparing oral immunosuppression and glaucoma surgery. This is, to our knowledge, the first case of bilateral refractory dengue-associated panuveitis from the Caribbean treated with combination steroid-sparing oral immunosuppression and bilateral glaucoma valve implantation.

    Primary hyperoxaluria type 1 (PH1) is a rare liver enzymatic defect that causes overproduction of plasma oxalate. Accumulation of oxalate in the kidney and subsequent renal failure are fatal to PH1 patients often in pediatric age. Combined liver and kidney transplantation is the therapy of choice for end-stage renal disease due to PH1. Levels of plasma oxalate remain elevated for several months after liver transplantation, as the residual body oxalate is slowly excreted. Patients with persistent hyperoxaluria after transplant often require hemodialysis, and accumulation of residual oxalate in the kidney can induce graft dysfunction. As the native kidneys are the main target of calcium oxalate accumulation, we postulated that removal of native kidneys could drastically decrease total body oxalate levels after transplantation. Here, we report a case of bilateral nephrectomy at the time of combined liver-kidney transplantation in a pediatric PH1 patient. Bilateral nephrectomy induced a rapid decrease in plasma oxalate to normal levels in less than 20 days, compared to the several months reported in the literature. Our results suggest that removal of native kidneys could be an effective strategy to decrease the need for hemodialysis and the risk of renal dysfunction after combined liver-kidney transplantation in patients with PH1.

    Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication that occurs in the luteal phase of an induced hormonal cycle. In most cases, the symptoms are self-limited and spontaneous regression occurs. However, severe cases are typically accompanied by acute respiratory distress. The objective of the present study was to describe the clinical presentation, treatment, and outcome of pleural effusion associated with OHSS in three patients undergoing in vitro fertilization. The patients ranged in age from 27 to 33 years. The onset of symptomatic pleural effusion (bilateral in all cases) occurred, on average, 43 days (range, 27-60 days) after initiation of hormone therapy for ovulation induction. All three patients required hospitalization for massive fluid resuscitation, and two required noninvasive mechanical ventilation. Although all three patients initially underwent thoracentesis, early recurrence of symptoms and pleural effusion prompted the use of drainage with a pigtail catheter. Despite the high output from the pleural drain (mean, 1,000 mL/day in the first week) and prolonged drainage (for 9-22 days), the outcomes were excellent: all three patients were discharged from hospital. Although pleural effusion secondary to OHSS is probably underdiagnosed, the associated morbidity should not be underestimated, especially because it affects potentially pregnant patients. In this study, early diagnosis and appropriate supportive measures yielded favorable results, limiting the surgical approach to adequate pleural drainage.

    The surgical treatment of patients with neglected developmental dysplasia of the hip (DDH) has been the subject of controversy. We asked if age affected outcome in patients with neglected DDH with unilateral or bilateral dislocation who underwent one-stage combined procedures. We retrospectively reviewed the results of 40 patients (51 hips) treated with a one-stage combined procedure consisting of open reduction, pelvic osteotomy, and femoral shortening. The average age at the time of surgery was 5.4 years for Group I (bilateral dislocation, 22 hips) and 6.7 years for Group II (unilateral dislocation, 29 hips). Mean followup was 5.4 years for Group I and 6.7 years for Group II. According to the modified score system of Trevor et al, 13 hips rated excellent, three were good, and six were fair in Group I; the ratings were 14, nine, and six hips respectively in Group II. Four patients had a limb-length discrepancy of approximately 1.5 cm in Group I. Twelve hips in Group I and 18 hips in Group II had osteonecrosis of varying severity. Our data suggest the outcomes of the children who were 5.5 years or younger in Group I and 8 years or younger in Group II were better. Level IV, case series.

Our objective was to introduce a uniportal VATS approach for simultaneous bilateral bullectomy and to evaluate its therapeutic efficacy. METHODS: Between May of 2011 and January of 2012, five patients underwent bilateral bullectomy conducted using this approach. All of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available. PMID:23503483

    Background Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of primary effusion lymphomas (PEL). PEL cell lines infected with KSHV, but negative for Epstein-Barr virus have a tumorigenic potential in non-obese diabetic/severe combined immunodeficient mice and result in efficient engraftment and formation of malignant ascites with notable abdominal distension, consistent with the clinical manifestations of PEL in humans. Methodology/Principal Findings Using this preclinical mouse model, we demonstrate that the combination of arsenic trioxide and interferon-alpha (IFN) inhibits proliferation, induces apoptosis and downregulates the latent viral transcripts LANA-1, v-FLIP and v-Cyc in PEL cells derived from malignant ascites. Furthermore, this combination decreases the peritoneal volume and synergistically increases survival of PEL mice. Conclusion/Significance These results provide a promising rationale for the therapeutic use of arsenic/IFN in PEL patients. PMID:24250827

    The study goal was to establish a standard industrial procedure for the measurement of thermal effusivity by a thermal microscope (TM), using a periodic heating method with a thermoreflectance (TR) technique. To accomplish this goal, a working group was organized that included four research institutes. Each institute followed the same procedure: a molybdenum (Mo) film was sputtered on the surface of Pyrex, yttria-stabilized zirconia (YSZ), alumina (Al2O3), Germanium (Ge), and silicon (Si) samples, and then the phase lag of the laser intensity modulation was measured by the resultant surface temperature. A procedure was proposed to calibrate the effect of 3D heat flow, based on the analytical solution of the heat conduction equation, and thermal effusivity was measured. The derived values show good agreement with literature values. As a result, the TM calibration procedure can be recommended for practical use in measuring the thermal effusivity in a small region of the materials.

    To report the case of bilateral congenital venous tortuosity and dilatation combined with cilioretinal artery. A 48-year-old woman complained of headache and underwent routine ophthalmic examination. The best-corrected visual acuity was 20/20 in both eyes. The examination of the fundus through a dilated pupil revealed that the retinal veins were strikingly tortuous and slightly dilated in the posterior pole and mid-peripheral retina of both eyes. However, the course and shape of the veins were normally straight in the peripheral retina. There was no change in the appearance and shape of the vein. The visual acuity remained unaffected during a 2-year follow-up. PMID:27103843

    The adenoid pad has been considered a reservoir for bacteria in the pathogenesis of otitis media with effusion. This study aimed to characterize the middle ear microbiota in children with otitis media with effusion and establish whether a correlation exists between the middle ear and adenoid microbiota. Prospective, controlled study. Middle ear aspirates adenoid pad swabs were collected from 23 children undergoing ventilation tube insertion. Adenoid swabs from patients without ear disease were controls. Samples were analyzed using 16S rRNA sequencing on the Illumina MiSeq platform. Thirty-five middle ear samples were collected. The middle ear effusion microbiota was dominated by Alloiococcus otitidis (23% mean relative abundance), Haemophilus (22%), Moraxella (5%), and Streptococcus (5%). Alloiococcus shared an inverse correlation with Haemophilus (P = .049) and was found in greater relative abundance in unilateral effusion (P = .004). The microbiota of bilateral effusions from the same patient were similar (P < .001). However, the otitis media with effusion microbiota were found to be dissimilar to that of the adenoid (P = .01), whereas the adenoid microbiota of otitis media with effusion and control patients were similar (P > .05) (permutational multivariate analysis of the variance). Dissimilarities between the local microbiota of the adenoid and the middle ear question the theory that the adenoid pad is a significant reservoir to the middle ear in children with otitis media with effusion. A otitidis had the greatest cumulative relative abundance, particularly in unilateral effusions, and shares an inverse correlation with the relative abundance of Haemophilus.

  17. Pleural effusions from congestive heart failure.

    PubMed

    Porcel, José M

    2010-12-01

    In heart failure (HF), pleural effusion results from increased interstitial fluid in the lung due to elevated pulmonary capillary pressure. Rarely, pleural effusions may occur in association with isolated right HF. HF-associated effusions are typically bilateral, but if unilateral, they are more commonly seen on the right side. The fluid typically meets the biochemical characteristics of a transudate, although in 25% of the cases it may fall into the exudative range. Testing for natriuretic peptides, such as NT-proBNP, significantly aids in diagnosing or excluding HF in patients with pleural effusion of unknown origin. The measurement of pleural fluid NT-proBNP is the best way to identify pleural effusions that meet the exudative criteria of Light but are due to HF. However, if natriuretic peptide assays are not available, calculation of the serum to pleural fluid albumin gradient represents a good substitute for making this distinction. Loop diuretics are the mainstay of therapy, although a therapeutic thoracentesis for very large effusions may occasionally be required.

    Complicated pleural effusions are difficult to manage with conventional strategies. In this study, we review the safety, efficacy, and durability of PleurX catheters (Denver Biomedical, Golden, CO) for managing complicated pleural effusions and describe a patient population who might benefit. From July 1999 to February 2003, 63 PleurX catheters were placed in 58 symptomatic patients (an additional five had bilateral catheters) to manage complicated pleural effusions. Patients selected for catheter placement tended to have poor performance status (Eastern Cooperative Oncology Group < or =2) or had failed standard therapies. Of the 63 catheters, 52 (83%) were placed because of malignant complicated pleural effusions. A registry of patients was constructed, and data were obtained from review of medical records. Nonparametric estimates of freedom from reintervention and overall survival were obtained by the Kaplan-Meier method. Catheter-related complications were noted in four of 58 patients (7%) and included one each of pneumothorax, seroma, empyema, and pain syndrome. Freedom from reintervention for effusion management was 95%. Of the patients, 86% (50 of 58) experienced dyspnea relief. There were no procedure-related mortalities. Catheters remained functional up to 330 days, and four of 63 (6%) required one-time thrombolysis with tissue plasminogen activator. PleurX catheters are safe, effective, and durable solutions for complicated pleural effusions and seem to provide an attractive alternative for patients who have few other palliative options. We consider the catheters as first-line therapy for these patients.

    We describe a 66-year-old man who developed bilateral choroidal detachment that was induced by unilateral topical administration of a fixed combination of 1% brinzolamide and 0.5% timolol maleate the day after an uneventful phacoemulsification surgery and intraocular lens implantation involving his right eye. We believe that the reaction was an idiosyncratic reaction, most likely against brinzolamide. The condition improved rapidly after the cessation of the fixed combination of brinzolamide and timolol maleate and treatment with 1% topical prednisolone acetate every hour and 1% cyclopentolate twice a day bilaterally. Although there are several similar cases involving choroidal detachment after oral acetazolamide and topical dorzolamide treatment mentioned in the literature, the present case is the first case report involving bilateral choroidal detachment after topical treatment with brinzolamide.

    AIM To assess the binocular visual function in bilateral cataract patients with unilateral astigmatism after combined implantations of Toric with multifocal intraocular lens (IOL), and to compare with that of Toric and monofocal IOL implantation. METHODS All the 30 patients with unilateral astigmatism suffered bilateral cataract were randomly divided into two groups: Toric plus multifocal IOL group and Toric plus monofocal IOL group. Uncorrected and corrected visual acuity at distance (5.0 m), intermediate distance (0.6 m), and near (0.33 m), contrast sensitivity, and stereopsis were assessed 6mo after surgery. Patients were also surveyed for visual disturbances and spectacle dependence. RESULTS Binocular uncorrected visual acuity (LogMAR) of Toric/multifocal IOL eyes at distance, intermediate, near were 0.05±0.05, 0.24±0.10, and 0.14±0.06 respectively. The values of Toric plus monofocal IOL eyes were 0.06±0.07, 0.26±0.08, and 0.37±0.10 respectively. These values did not indicate significant differences between two groups with exception of near visual acuity. In the photopic condition (with or without glare), the contrast sensitivity of multifocal IOL eyes was significant lower than the monofocal IOL eyes in 18 cpd. In the mesopic condition, the contrast sensitivity of multifocal group was significant lower than monofocal group in 12 cpd, and in mesopic glare condition, this significant difference was found both in 6 cpd and 12 cpd. The stereopsis of Toric/multifocal IOL eyes decreased slightly (100±80 seconds of arc, t=2.222, P=0.136). Mean near vision for patient satisfaction was statistically significantly higher in Toric/multifocal IOL group patients versus than that in Toric/monofocal IOL group (80% vs 25.5%, P=0.000). Visual disturbance was not noticed in either group. CONCLUSION Although the combination of Toric and multifocal IOL implantation results in compromising stereoacuity, it can still provide patients with high levels of spectacle freedom and

    Objective To investigate the efficacy, safety, and microbiology of a thermosensitive otic suspension of ciprofloxacin (OTO-201) in children with bilateral middle ear effusion undergoing tympanostomy tube placement. Study Design Two randomized, double-blind, sham-controlled phase 3 trials. Patients were randomized to intratympanic OTO-201 or sham. Setting Children with bilateral middle ear effusion undergoing tympanostomy tube placement. Subjects/Methods Studies evaluated 532 patients (6 months to 17 years old) in a combined analysis of efficacy (treatment failure: presence of otorrhea, otic or systemic antibiotic use, lost to follow-up, missed visits), safety (audiometry, otoscopy, tympanometry), and microbiology. Results There was a lower cumulative proportion of treatment failures in patients receiving OTO-201 vs tympanostomy tubes alone (1) on days 4, 8, 15, and 29; (2) on day 15, primary end point (23.0% vs 45.1%; age-adjusted odds ratio, 0.341; P < .001; reduction in relative risk, 49%); and (3) on day 15, blinded-assessor otorrhea treatment failure (7.0% vs 19.4%; age-adjusted odds ratio, 0.303; P < .001; reduction in relative risk, 64%). Per-protocol and subgroup analyses (baseline demographics, pathogen type, culture status, effusion type, microbiologic response) supported these findings. There were no drug-related serious adverse events; the most frequent treatment-emergent adverse events in both groups were pyrexia, postoperative pain, nasopharyngitis, cough, and upper respiratory tract infection. OTO-201 administration had no evidence of increased tube occlusion and no negative effect on audiometry, tympanometry, or otoscopy. Conclusions Combined analysis of 2 phase 3 trials demonstrated a lower cumulative proportion of treatment failures through day 15 compared with TT alone when OTO-201 was administered intratympanically for otitis media with bilateral middle ear effusion at time of tympanostomy tube placement.

  3. Pericardial and pleural effusions in congestive heart failure-anatomical, pathophysiologic, and clinical considerations.

    PubMed

    Natanzon, Alex; Kronzon, Itzhak

    2009-09-01

    Transudative pleural and pericardial effusions are not uncommon in patients with congestive heart failure. Pericardial effusion forms only with elevation of the right-sided filling pressure in the heart. In patients with biventricular failure, there is no evidence that elevated left-sided pressure, in the absence of elevated right-sided pressure, can cause a pericardial effusion. Pleural effusion forms with acute elevation of the right-sided or the left-sided filling pressure in the heart. In patients with congestive heart failure, elevated right-sided filling pressures are less common than elevated left-sided filling pressures, thus, explaining a lower prevalence of pericardial than pleural effusions. Pleural effusions in patients with congestive heart failure are typically bilateral. However, a unilateral pleural effusion is more commonly seen on the right side. Although multiple theories attempt to explain the right-sided preponderance of pleural effusion, to date, no mechanism has been universally accepted or experimentally proven.

    Background New, effective chemotherapeutic agents are needed for intraocular retinoblastoma. Methods Our institutional clinical trial sought to estimate the rate of response to 2 courses of vincristine and topotecan (VT) window therapy in patients with bilateral retinoblastoma and advanced disease (Reese-Ellsworth Group IV or V) in at least one eye. The topotecan dose started at 3 mg/m2/day for 5 days, and was adjusted to target a systemic exposure of 140 ± 20 ng/ml*hr. The vincristine dose was 0.05 mg/kg for patients < 12 months of age and 1.5 mg/m2 for those > 12 months of age at diagnosis. Results From February 2005 to June 2010, 27 patients received VT window therapy. Median age at enrollment was 8.1 months (range, 0.7–22.1 months). Twenty-four patients (88.9%) responded to window therapy (95% CI, 71.3%–96.9%). Hematologic toxicity comprised grade 4 neutropenia (n=27), grade 3 anemia (n=19), and grade 3/4 thrombocytopenia (n=16). Thirteen patients had grade 3 non-hematologic toxicity. G-CSF support was added after 10 patients had been treated and significantly reduced the duration of grade 4 neutropenia (median, 7 vs. 24 days; P <0.001). Pharmacokinetic studies showed rapid changes in topotecan clearance rates during the first year of life. Conclusions The combination of topotecan and vincristine is effective for the treatment of advanced intraocular retinoblastoma. G-CSF treatment alleviates the duration of grade 4 neutropenia. Appropriate topotecan starting doses for patients 0–3, 3–6, 6–9, 9–12, and >12 months of age are specified. PMID:22516936

    Objective To investigate the combined effect of bilateral ovariectomy (OVX) and anterior cruciate ligament transection (ACLT) with medial meniscectomy (MM) on the development of osteoarthritis (OA). Methods Twenty female 15-week-old Sprague-Dawley rats were used. Five rats in each group underwent bilateral OVX (OVX group), bilateral ACLT with MM (ACLT with MM group), bilateral OVX plus ACLT with MM (OVX plus ACLT with MM group), and sham surgery (SHAM group). All the rats were subjected to treadmill running for 4 weeks. The behavioral evaluation for induction of OA used the number of rears method, and this was conducted at 1, 2, and 4 weeks post-surgery. Bone mineral density (BMD) was calculated with micro-computerized tomography images and the modified Mankin's scoring was used for the histological changes. Results The number of rears in the OVX plus ACLT with MM group decreased gradually and more rapidly in the ACLT with MM group. Histologically, the OVX plus ACLT with MM group had a significantly higher modified Mankin's score than the OVX group (p=0.008) and the SHAM group (p=0.008). BMDs of the OVX plus ACLT with MM group were significantly lower than the SHAM group (p=0.002), and the ACLT with MM group (p=0.003). Conclusion We found that bilateral OVX plus ACLT with MM induced definite OA change in terms of histology and BMD compared to bilateral OVX and ACLT with MM alone. Therefore, OVX and ACLT with MM was an appropriate degenerative OA rat model. PMID:27606264

    PEL is a B-cell non-Hodgkin lymphoma, occurring predominantly as a lymphomatous effusion in body cavities, characterized by aggressive clinical course, with no standard therapy. Based on previous reports that PEL cells display a Warburg phenotype, we hypothesized that the highly hypoxic environment in which they grow in vivo makes them more reliant on glycolysis, and more vulnerable to drugs targeting this pathway. We established here that indeed PEL cells in hypoxia are more sensitive to glycolysis inhibition. Furthermore, since PI3K/Akt/mTOR has been proposed as a drug target in PEL, we ascertained that pathway-specific inhibitors, namely the dual PI3K and mTOR inhibitor, PF-04691502, and the Akt inhibitor, Akti 1/2, display improved cytotoxicity to PEL cells in hypoxic conditions. Unexpectedly, we found that these drugs reduce lactate production/extracellular acidification rate, and, in combination with the glycolysis inhibitor 2-deoxyglucose (2-DG), they shift PEL cells metabolism from aerobic glycolysis towards oxidative respiration. Moreover, the associations possess strong synergistic cytotoxicity towards PEL cells, and thus may reduce adverse reaction in vivo, while displaying very low toxicity to normal lymphocytes. Finally, we showed that the association of 2-DG and PF-04691502 maintains its cytotoxic and proapoptotic effect also in PEL cells co-cultured with human primary mesothelial cells, a condition known to mimic the in vivo environment and to exert a protective and pro-survival action. All together, these results provide a compelling rationale for the clinical development of new therapies for the treatment of PEL, based on combined targeting of glycolytic metabolism and constitutively activated signaling pathways.

    We describe a straightforward, reliable, and inexpensive design of a Knudsen type molecular effusion cell capable of measuring molecular evaporation rates in situ. This is accomplished by means of a quartz crystal microbalance integrated into the shutter of the effusion cell. The presented layout facilitates both the measurement of effusion rates under ultrahigh vacuum conditions without the need for a separate experimental setup and the growth of surface supported molecular layers and nanostructures. As an important prerequisite for reproducible deposition of molecular films with defined coverages ranging from submonolayers up to multilayers, the Knudsen cell features a stable deposition rate for crucible temperatures between 50 and 500 degrees C. Experimental determination of deposition rates for different crucible temperatures allows to approximate sublimation enthalpies of the evaporant based on the Clausius-Clapeyron equation.

    Purpose: To evaluate the outcome of treatment for buccal cancers and assess the impact of unilateral vs. bilateral adjuvant neck radiation. Methods and Materials: We retrospectively reviewed the course of 145 patients newly diagnosed with buccal squamous cell carcinoma without distant metastases who completed definitive treatment between January 1994 and December 2000. Of 145 patients, 112 (77%) had Stage III or IV disease. All underwent radical surgery with postoperative radiotherapy (median dose, 64 Gy), including unilateral neck treatment in most (n = 120, 82.8%). After 1997, cisplatin-based concomitant chemoradiotherapy was given for high-risk patients with more than two involved lymph nodes, extracapsular spread, and/or positive margins. Results: The 5-year disease-specific survival rate for Stages I-IV was 87%, 83%, 61%, and 60%, respectively (p = 0.01). The most significant prognostic factor was N stage, with the 5-year disease-specific survival rate for N0, N1, and N2 being 79%, 65%, and 54%, respectively (p 0.001). For patients with more than two lymph nodes or positive extracapsular spread, cisplatin-based concomitant chemoradiotherapy improved locoregional control (p = 0.02). Locoregional control did not differ between patients undergoing unilateral or bilateral neck treatments (p = 0.95). Contralateral neck failure occurred in only 2.1%. Conclusions: In patients with buccal carcinoma after radical resection, ipsilateral neck radiation is adequate. Bilateral prophylactic neck treatment does not confer an added benefit.

    Pleural effusion occurs often in patients with left heart failure. There are no large-scale clinical studies investigating the incidence of pleural effusion in patients with right heart failure (RHF) alone. To determine the incidence of pleural effusions in patients with idiopathic pulmonary arterial hypertension (IPAH) and familial pulmonary arterial hypertension (FPAH). Consecutive IPAH and FPAH patients who were treated at Vanderbilt University Medical Center were retrospectively studied. Pleural effusions were detected by chest radiograph, chest CT scan, ultrasound, or autopsy. Thirty-one of 147 patients (21.1%) with IPAH (128 patients) or FPAH (19 patients) had pleural effusions. Ten patients had explanations for the pleural effusions other than RHF. Two patients had no obvious explanations. The remaining 19 patients had RHF. When compared with the patients without pleural effusions, the patients with pleural effusions due to RHF had significantly higher mean right atrial pressure (16.0 +/- 6.8 vs 8.8 +/- 5.5 mm Hg, respectively; p < 0.001). There was no significant difference in other hemodynamic parameters between the two patient groups. The majority of effusions due to RHF are trace to small (63.2%) and right sided (57.9%) or bilateral (26.3%). Of the 19 patients with pleural effusions due to RHF, 8 patients had ascites, and 1 patient had moderate pericardial effusion. Four of the five patients who underwent thoracentesis had transudates. Our study in IPAH and FPAH patients demonstrates that pleural effusions frequently occur in patients with isolated RHF.

    Congenital bilateral perisylvian syndrome (CBPS) is characterized by epilepsy, cognitive deficits, pseudobulbar palsy and diplegia of the facial, pharyngeal and masticatory muscles. Epilepsy has been described in nearly 90% of affected patients. The epilepsy is usually severe and pharmacoresistant in about 55 percent of CBPS patients. Until now, only 12 cases of surgical treatment on CBPS have been reported; the surgical treatment is usually corpus callosotomy. In this paper, we describe a previously unreported combination of anterior corpus callosotomy plus anterior temporal lobectomy with amygdalohippocampectomy for a patient with CBPS, resulting in a satisfactory clinical outcome. Based on this case, we suggest that palliative focal resective surgery combined with anterior corpus callosotomy should be considered when a predominance of the epileptiform discharges suggests focal onset in patients with CBPS. Meanwhile, the clinical decision to adopt this combination surgery must be based on a thorough pre-surgical evaluation, and should take into account the clinical, radiological, and EEG features.

    This article describes the use of autogenous coronoid process grafts for lengthening the ramus in patients with long-standing temporomandibular joint (TMJ) ankylosis and severe mandibular retrognathia. A retrospective clinical study of 6 cases of bilateral TMJ ankylosis surgically treated during a 3-year period from June 1996 to March 1999 was performed. All patients were treated by condylectomy, mandibular sagittal split osteotomy, and immediate autogenous coronoid process grafts. Clinical examination, radiographs, and photographs were used postsurgically to evaluate the grafts, condylar function, and facial appearance. Very satisfactory postsurgical results were obtained in terms of function of the TMJ, the airway, and aesthetics. In children suffering from TMJ ankylosis, the coronoid process can be used for mandibular lengthening.

    The purpose of this study was to clarify the safety and feasibility of a 6-day protocol of bilateral repetitive transcranial magnetic stimulation (rTMS) combined with intensive swallowing rehabilitation for chronic poststroke dysphagia. In-hospital treatment was provided to 4 poststroke patients (age at treatment: 56–80 years; interval between onset of stroke and treatment: 24–37 months) with dysphagia. Over 6 consecutive days, each patient received 10 sessions of rTMS at 3 Hz applied to the pharyngeal motor cortex bilaterally, followed by 20 min of intensive swallowing rehabilitation exercise. The swallowing function was evaluated by the Penetration Aspiration Scale (PAS), Modified Mann Assessment of Swallowing Ability (MMASA), Functional Oral Intake Scale (FOIS), laryngeal elevation delay time (LEDT) and Repetitive Saliva-Swallowing Test (RSST) on admission and at discharge. All patients completed the 6-day treatment protocol and none showed any adverse reactions throughout the treatment. The combination treatment improved laryngeal elevation delay time in all patients. Our proposed protocol of rTMS plus swallowing rehabilitation exercise seems to be safe and feasible for chronic stroke dysphagia, although its efficacy needs to be confirmed in a large number of patients.

    Uniportal video-assisted thoracic surgery (VATS) is carried out to reduce postoperative pain after treatment of thoracic diseases. Here, we report a novel method that combines a subxiphoid and intercostal uniportal VATS approach that can be used to treat bilateral pulmonary lesions simultaneously. The first case is a 50-year-old female with bilateral pulmonary lesions who received left lower lobectomy associated with right middle lobe wedge resection synchronously; the other case is a 14-year-old male who was admitted for resection of bilateral lung metastases as a result of previous osteosarcoma. We combined a subxiphoid approach with intercostal uniportal surgical procedure for bilateral pulmonary lesions. Less postoperative pain, faster postoperative recovery, and a better aesthetic effect are possible superiorities of this method if patients are selected carefully. Our results show that the combining of a subxiphoid approach with intercostal uniportal VATS is a feasible and efficient surgical procedure for bilateral pulmonary lesions, with good outcomes. Moreover, this procedure is more suitable for patients with bilateral pulmonary lesions.

    Fifty per cent of children with serous otitis media may have some balance disturbances. To evaluate vestibular function in children with otitis media with effusion. The control group comprised 25 children with bilateral normal hearing and middle-ear function. The study group consisted of 30 children with bilateral otitis media with effusion; these were divided into 2 subgroups according to air-bone gap size. Measures included the Arabic Dizziness Handicap Inventory, an imbalance evaluation sheet for children, vestibular bedside tests for children, and air- and bone-conducted vestibular-evoked myogenic potential testing. Arabic Dizziness Handicap Inventory scores and some vestibular bedside test results were significantly abnormal, with normal video-nystagmography results, in children with otitis media with effusion. Air-conducted vestibular-evoked myogenic potentials were recorded in 73 per cent of children with otitis media with effusion, with significantly delayed latencies. Bone-conducted vestibular-evoked myogenic potentials were successfully detected in 100 per cent of children with otitis media with effusion with similar results to the control group. The Arabic Dizziness Handicap Inventory and vestibular bedside tests are valuable tools for detecting vestibular impairment in children. Bone-conducted vestibular-evoked myogenic potentials are useful for vestibular system evaluation.

    2016-01-01

    Abstract Primary intestinal lymphangiectasia (PIL) is a rare disorder of unknown etiology characterized by diffuse or localized dilation and eventual rupture of the enteric lymphatic vessels in mucosa, submucosa, and/or subserosa. Lymph, rich in all kinds of proteins and lymphocytes, leaks into the gastrointestinal tract via the affected lymphatic vessels causing hypoproteinemia and lymphopenia. The main symptom is variable degrees of pitting edemas of bilateral lower limbs. But edemas of any other parts of body, and mild serous effusions may also occur sometimes. PIL occurs in conjunction with a right hemifacial edema, a right upper limb lymphedema, asymmetric bilateral calves edemas, and a unilateral massive pleural effusion seems never to be reported before. In addition, increased enteric protein loss that may cause severe hypoproteinemia usually get overlooked, and the lymphatic system disorders always put the diagnoses in a dilemma. We described a case of a 17-year-old Chinese girl with a history of gradually progressive swellings of right-sided face, right upper limb, and bilateral calves since 3 to 4 months of age. A right-sided massive pleural effusion, a moderate pericardial effusion, and a mild ascites have been proved unchanged by a series of computerized tomography (CT) scans since 5 years ago. The diagnosis of PIL was finally confirmed by severe hypoproteinemia, endoscopic changes, and histology of jejunum biopsy. Further lymphoscintigraphy and lymphangiography also identified lymph leakage in her bowel and several abnormal lymphatic vessels. A high-protein, low-fat diet supplemented with medium-chain triglycerides (MCT) showed some benefit. This case suggested that PIL was a rare but important etiology of hypoproteinemia, effusions, and edemas. PIL, effusions, and lymphedema can be the features of multisegmental generalized lymphatic dysplasia. In addition, both lymphoscintigraphy and intranodal lymphangiography could be considered when lymphatic

    Five patients with true convergence excess esotropia were surgically managed with combined resection and recession of the medial rectus muscles. This technique was chosen to address the near/distance angle disparity. The use of this surgical technique produced full asymptomatic binocular control at near and distance fixation in four patients. One patient developed a consecutive exotropia but regained full binocular control following a second surgical procedure.

    Patient: Male, 32 Final Diagnosis: Pericardial effusion related to the consumption of herbal product Symptoms: Dyspnea Medication: Horse chestnut (Aesculus hippocastanum L) Clinical Procedure: Pericardial and pleural effusions were drained through a pericardiopleural window Specialty: Cardiology Objective: Unusual clinical course Background: There are many well-known causes of pericardial effusion, such as cancer metastasis, bacterial or viral pericarditis, and uremic pericarditis; however, no reports exist in the literature demonstrating a pericardial effusion that led to cardiac tamponade following consumption of an herbal remedy. Case Report: A 32-year-old male patient was referred to our cardiology outpatient clinic with a complaint of dyspnea. The patient’s medical history was unremarkable; however, he had consumed 3 boxes of horse chestnut (Aesculus hippocastanum L) paste over the previous 1.5 months. His chest x-ray examination revealed an enlarged cardiac shadow and bilateral pleural effusion. On transthoracic echocardiographic examination, his ejection fraction was found to be 55% with circumferentially extended pericardial effusion that reached 3.9 cm at its maximal thickness. No growth had been detected in the pericardial and pleural biopsies or blood samples; there was no evidence of an infectious process in the physical examination. Based on this information, we diagnosed pericarditis resulting from the use of herbal remedies. This is the first report to demonstrate that herbal remedy consumption may cause this type of clinical condition. Conclusions: Besides other well-known causes, pericardial effusion related to the consumption of herbal remedies should always be considered when treating patients with pericardial effusion caused by unclear etiologies.

    The involvement of the pericardium by metastatic tumors is not uncommon, particularly in patients with lung cancer, breast cancer, lymphomas, leukemias, and melanomas. There are five therapeutic modalities for the treatment of malignant pericardial effusion, including pericardiocentesis, pericardial sclerosis, systemic chemotherapy, radiotherapy, and surgical treatment. The optimal treatment selection is dependent principally on a patient's life expectancy; responsiveness of the tumor to chemotherapy, irradiation, or both; and whether or not cardiac tamponade is present at diagnosis. The overall prognosis of patients with malignant pericardial effusion is primarily influenced by the extent and histologic features of the underlying cancer. Although this condition is usually incurable, a reasonable period of useful palliation can be obtained in most patients. Images PMID:2471362

    Although it is curable, tuberculosis remains one of the most frequent causes of pleural effusions on a global scale, especially in developing countries. Tuberculous pleural effusion (TPE) is one of the most common forms of extrapulmonary tuberculosis. TPE usually presents as an acute illness with fever, cough and pleuritic chest pain. The pleural fluid is an exudate that usually has predominantly lymphocytes. The gold standard for the diagnosis of TPE remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli, Although adenosine deaminase and interferon-γ in pleural fluid have been documented to be useful tests for the diagnosis of TPE. It can be accepted that in areas with high tuberculosis prevalence, the easiest way to establish the diagnosis of TPE in a patient with a lymphocytic pleural effusion is to generally demonstrate a adenosine deaminase level above 40 U/L. The recommended treatment for TPE is a regimen with isoniazid, rifampin, and pyrazinamide for two months followed by four months of two drugs, isoniazid and rifampin. PMID:27499981

    Introduction  Otitis media with effusion (OME) is a leading cause of hearing impairment in children. Therefore, early and proper management is essential. Objectives  The objective of this research is to assess the efficacy of intratympanic (IT) steroids injection for management of otitis media with effusion (OME). Methods  This study involved 42 children (84 ears) with bilateral OME. We used tympanometry to confirm the childreńs middle ear effusion and pure tone audiometry to determine hearing threshold. We performed myringotomy and inserted ventilation tubes (VTs) bilaterally, followed by a steroid injection of 0.4–0.6 mL methylprednisolone (40 mg/mL) into one randomly selected middle ear. This procedure was followed by once-weekly administration of steroids (0.5 mL methylprednisolone at a concentration of 40 mg/mL) into the middle ear for three consecutive weeks. Results  We found recurrent OME after VT alone in nine (21.4%) ears; whereas, after VT combined with steroid administration, we found two (4.76%), with statistically significant difference. We noted tympanosclerosis postoperatively in six (12.9%) ears and in one of the injected ears (2.3%) (p = 0.0484). Otorrhea occurred in eight (19%) ears with VT alone and in three (7.1%) injected ears, with non-significant difference. The duration between VT insertion and its extrusion was 6.6 = 1.1 months for ears with VT alone and 6.95 =1.12 months in injected ears (p = 0.1541 NS). Conclusion  IT Steroids injection for treatment of OME is a safe and simple intervention with lower incidence of symptoms recurrence and postoperative complications. Thus, its use in management of OME is recommended. PMID:27413407

    The current study examined how cochlear implant (CI) listeners combine temporally interleaved envelope-ITD information across two sites of stimulation. When two cochlear sites jointly transmit ITD information, one possibility is that CI listeners can extract the most reliable ITD cues available. As a result, ITD sensitivity would be sustained or enhanced compared to single-site stimulation. Alternatively, mutual interference across multiple sites of ITD stimulation could worsen dual-site performance compared to listening to the better of two electrode pairs. Two experiments used direct stimulation to examine how CI users can integrate ITDs across two pairs of electrodes. Experiment 1 tested ITD discrimination for two stimulation sites using 100-Hz sinusoidally modulated 1000-pps-carrier pulse trains. Experiment 2 used the same stimuli ramped with 100 ms windows, as a control condition with minimized onset cues. For all stimuli, performance improved monotonically with increasing modulation depth. Results show that when CI listeners are stimulated with electrode pairs at two cochlear sites, sensitivity to ITDs was similar to that seen when only the electrode pair with better sensitivity was activated. None of the listeners showed a decrement in performance from the worse electrode pair. This could be achieved either by listening to the better electrode pair or by truly integrating the information across cochlear sites. PMID:24653681

  6. Diagnostic Tools of Pleural Effusion

    2014-01-01

    Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed by radiological studies including simple chest radiography, ultrasonography, or computed tomography. Identifying the causes of pleural effusions by pleural fluid analysis is essential for proper treatments. This review article provides information on the diagnostic approaches of pleural effusions and further suggested ways to confirm their various etiologies, by using the most recent journals for references.

Her effusions resolved with the cessation of hydrochlorothiazide and normalisation of her blood sodium levels by fluid restriction. This case displays a novel association of hyponatraemia as a possible mechanism for the development of bilateral acute angle closure.

    Realize the surgery of sinus lifting floor to allow the installation of osseointegrated implants for oral rehabilitation, with the combination of different biomaterials, autogenous bone and lyophilized bovine bone. Oral rehabilitation using the installation of osseointegrated implants is an alternative surgical approach that results in the satisfactory form, function and esthetics of the dental units. After clinical, dental and laboratory assessment, a 47-year-old female patient underwent full maxillary oral rehabilitation involving the installation of osseointegrated implants to allow her to meet the physiological demands of occlusion and mastication. It was found that the patient had fully pneumatized maxillary sinuses with insufficient height to anchor implants, with a loss of the vertical dimension of the occlusal and masticatory functions due to general dental loss, compounded by the use of ill-fitting dentures; hence, the choice was made to take autogenous bone from the patient's chin area and supplement it with lyophilized bovine bone as collateral for larger areas to be grafted. It was also decided to avulse the remaining tooth units due to their impairment by periodontal disease. Bone grafts do not constitute suitable alternatives in the cosmetic and functional rehabilitation of the maxilla in patients requiring bilateral sinus elevation. The chin region provides bone tissue that, when complemented by lyophilized bovine bone grafts, ensures greater volume and less invasive surgery. In the case described here, a height gain of approximately 550% was obtained, making it possible to anchor seven implants. In this study, the surgical procedures used for grafting a combination of autogenous and lyophilized bovine bone, aimed to elevate the maxillary sinus floor to allow the installation of osseointegrated implants for oral rehabilitation.

    Estrogen deprivation is a high risk of cognitive dysfunction in neurodegenerative diseases, and the early used estrogen replacement has been proved effective in many studies. Because of the adverse actions, selective estrogen receptor modulating has been raised to substitute for estrogen replacement. In this study, we observed in hippocampus of bilaterally ovariectomized rats that the level of estrogen receptor α (ERα) was decreased in nuclei with activated glycogen synthase kinase-3β (GSK-3β) in cytoplasm at 8 weeks after operation. The level of nuclear ERα is important for its transcriptional property, and the inhibition of GSK-3β benefits to ERα nuclear translocation. Then, we used 4,4k,4a-(4-propyl-[1H]-pyrazole-1, 3, 5-triyl) trisphenol (PPT) (1 mg/kg/day), an agonist of ERα, combined with LiCl (40 mg/kg/day), an inhibitor of GSK-3β, to treat the ovariectomized rats. After the combination treatment of these two drugs (PPT + LiCl), the improved learning and memory abilities of ovariectomized rats in Morris water maze, increased dendritic spines in CA1 region, and decreased tau phosphorylation at Ser-396 in hippocampus were observed. Furthermore, PPT + LiCl treatment significantly increased ERα level in the nuclear fraction of hippocampus, and in the cytoplasmic fraction, the total level of GSK-3β was declined after treatment with its increased phosphorylation at Ser-9 (inactivation form). This study suggested that PPT + LiCl treatment could inhibit the activation of cytoplasmic GSK-3β and promote the nuclear translocation of ERα, and ERα together with GSK-3β maybe the targets to preserve hippocampus-dependent cognitive ability after long-term ovariectomy.

    To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    Idiopathic eosinophilic pleural effusions (IEPEs) comprise the eosinophilic pleural effusions for which a specific aetiology cannot be established. There are no reports investigating IEPE on the basis of a systematically applied pleuroscopy approach and entailing an appropriate patient follow-up till the final outcome is established; existing series rather combine clinical and thoracocentesis criteria to establish the idiopathic character of the diagnosis. The aim of our study was to assess the clinical outcome of patients with IEPE, who underwent a systematic diagnostic approach by pleuroscopy. We studied 10 patients with IEPE among 175 consecutive patients who underwent pleuroscopy for undiagnosed pleural effusion. Pleural biopsies were obtained from observed lesions. All patients were followed up by means of clinical examination and imaging. The diagnosis of IEPE was established in 10 patients (median age was 50.5 years, range 35-91). Macroscopic examination of the pleura showed diffuse thickening with pleural plaques in eight patients, consistent with diffuse pleural eosinophilic inflammation histologically proven. In two patients, macroscopic examination showed scattered nodules associated with non-caseating granulomas histologically. In all 10 patients, a specific aetiology could not be established. Follow-up was available for all patients ranging from 24-102 months (median 60 months). No patient received a specific treatment during the follow-up period. No relapse of a pleural effusion was documented during this period. Pleuroscopy is mandatory in diagnosing IEPE. Negative histology and a long follow-up showed a benign course. These findings suggest that we should call these effusions 'indeterminate'. © 2014 John Wiley & Sons Ltd.

    Pleural effusion (PE) is a very uncommon manifestation of sarcoidosis. It is equally observed in men and women, can appear at any age and in all radiologic stages, though it is more common in stages i and ii. Effusions have usually a mild or medium size and mainly involve the right side. Various mechanisms can be implicated. PE will be a serous exudate if there is an increase in the capillary permeability due to direct involvement of the pleural membrane, a chylothorax if mediastinum lymph nodes compress the thoracic duct and/or the lymphatic drainage from the pleural cavity, an hemothorax if granuloma compress or invade pleural small vessels or capillaries, and even a transudate if there is compression of the inferior vena cava, atelectasis due to complete bronchial obstruction or when the resolution of the PE is incomplete with chronic thickening of visceral pleura (trapped lung). It manifests biochemically as a pauci-cellular exudate with a predominance of lymphocytes, though there can be a preponderance of eosinophils or neutrophils. Protein concentrations are usually proportionately higher than lactate dehidrogenase, adenosine deaminase is normally low and it is possible to find increased levels of CA-125 in women. The tuberculin test is negative and pleural or lung biopsies yield the diagnosis by confirming the presence of non-caseating granulomata. These PE can have a favorable self-limited outcome, even though in most cases treatment with corticosteroids is needed, while surgery is required in a few cases.

    Objective The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006). Conclusion Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Preeclampsia is defined as new onset hypertension and proteinuria after 20 weeks of gestation and complicates approximately 2-8% of all pregnancies. Release of vasoconstrictive agents, endothelial damage, hyperpermeability of the capillaries and microangiopathic haemolysis involves the basic pathophysiology. It has variable clinical presentation. Here, we report a case of severe preeclampsia who developed postpartum massive ascites and pleural effusion. Primigravid patient was admitted to our clinic at 35 weeks of gestation with very high blood pressure. In biochemical analysis, Alanine aminotransferase (ALT) was 401 U/L, Aspartate aminotransferase (AST) was 292 U/L. An emergency caesarean section was performed because of fetal distress. On the 2nd post-operative day, abdominal distension and severe abdominal pain occurred. On the 3rd post-operative day, her abdominal distension increased and Ultrasonography (USG) revealed massive ascites. Abdominal drainage was performed and albumin infusion was administered. On postoperative day 4, she still had abdominal distension and concomitant respiratory distress. Computed Tomography (CT) showed ascites and bilateral pleural effusion. Her complaint regressed on the following days.

    To investigate the feasibility and therapeutic effect of free posterior interrosseous artery flap in a bridge fashion for combined skin and bilateral artery defects at palmar side of fingers. 6 cases with combined skin and bilateral artery defects at palmar side of fingers were treated with long-pedicled free posterior interrosseous artery flap in a bridge fashion. The flap size ranged from 3.5 cm x 2.0 cm to 6.5 em x 3.0 cm. The wounds at donor sites were closed directly. All the 6 flaps survived completely without any complication, and the wounds healed primarily. The blood supply and vein drainage in all the 6 fingers were normal. 4 cases were followed up for 1-12 months (average, 7 months). Satisfactory cosmetic and functional results were achieved. The flaps looked a little bit thicker than the surrounding tissue. The long-pedicled free posterior interrosseous artery flap in a bridge fashion is a good option for reconstruction of the combined skin and bilateral artery defects at palmar side of fingers in one stage.

    Pleural effusion in children is most often due to bacterial pneumonia. Between 0.6 and 2% of pneumonias are complicated by empyema and approximately 40% of children hospitalized with pneumonia have a pleural effusion. In recent years Streptococcus pneumoniae is the most prevalent organism. Treatment is based on the early and judicious use of antibiotics, imaging techniques, thoracocentesis, pleural drainage, fibrinolytics, thoracoscopy and thoracotomy. Indications for early pleural drainage are gross pus, positive Gram stain in pleural fluid, pleural glucose less than 50mg/dL, pleural fluid pH of less than 7 and sonographic evidence of loculations. Local fibrinolytics may decrease the need for surgical treatment, with a success rate between 38 and 100%, according to the effusion stage. Thoracoscopic debridement is useful in the fibrinopurulent stage with loculations, with favorable results in 30-100% of patients, also depending on the effusion stage.

    Recurrent pleural effusions are associated with significant morbidity and mortality. Drug-related reactions causing pleural effusions are not common, but their identification can potentially improve patient outcome. Minoxidil has been implicated in pleuropericardial effusions in patients with chronic kidney disease. The exact mechanism by which pleural effusion occurs is still unclear. We report a case of isolated exudative pleural effusion associated with minoxidil in a patient without underlying kidney disease that almost completely resolved after the drug was discontinued.

    Pleural infections have high morbidity and mortality, and their incidence in all age groups is growing worldwide. Not all infectious effusions are parapneumonic and, in such cases, the organisms found in the pleural space are not the same as those observed in lung parenchyma infections. The diagnostic difficulty lies in knowing whether an infectious effusion will evolve into a complicated effusion/empyema, as the diagnostic methods used for this purpose provide poor results. The mainstays of treatment are to establish an early diagnosis and to commence an antibiotic regimen and chest drain as soon as possible. This should preferably be carried out with fine tubes, due to certain morphological, bacteriological and biochemical characteristics of the pleural fluid. Fluid analysis, particularly pH, is the most reliable method for assessing evolution. In a subgroup of patients, fibrinolytics may help to improve recovery, and their combination with DNase has been found to obtain better results. If medical treatment fails and surgery is required, video-assisted thoracoscopic surgery (VATS) is, at least, comparable to decortication by thoracotomy, so should only undertaken if previous techniques have failed. Further clinical trials are needed to analyze factors that could affect the results obtained, in order to define new evidence-based diagnostic and therapeutic strategies that provide more effective, standardized management of this disease.

    The en-bloc resection of neoplasms on the abdominal wall often causes extensive defects that are difficult to manage. The anterolateral thigh (ALT) flap is a widely used flap in reconstructive surgery of defects. In this article, we present a case using bilateral pedicle anterolateral thigh flaps combined with a surgical polymesh to repair a large defect (22 cm × 18 cm) caused by dissection of a recurrent fibromatosis with good functional and aesthetic effects. There were no obvious morbidities or complications during a 6-month follow-up period.We conclude that the bilateral pedicle anterolateral thigh flap is a good choice for reconstruction of large lower abdominal wall defects. It can afford sufficient soft tissue coverage without obvious donor site morbidity.

    An 83-year-old man, who was a former smoker, with anti-ribonucleoprotein (RNP) antibody-positive combined pulmonary fibrosis and emphysema presented with a cough and dyspnea. A chest radiograph showed bilateral pleural effusions. His laboratory data showed proteinuria and elevated levels of anti-nuclear antibodies, anti-double strand DNA antibodies, and CA125, with decreased serum complement levels. Thoracentesis showed an exudative pleural effusion with an increased lymphocyte count and elevated CA125 levels. A thoracoscopic biopsy specimen showed proliferation of CA125-positive mesothelial cells. Systemic lupus erythematosus was diagnosed. His symptoms and pleural effusion resolved after the initiation of systemic corticosteroid therapy. The detection of anti-RNP antibody and CA125 levels are helpful in the diagnosis of lupus pleuritis.

    Buffalo chest refers to the pleuro-pleural communication that results in a single pleural cavity. Iatrogenic buffalo chest can occur following heart or heart-lung transplantation and other major thoracic surgeries. We present the case of malignant pleural mesothelioma in which iatrogenic buffalo chest after extended thymectomy caused bilateral pneumothoraces and contralateral dissemination of the disease. The free communication between bilateral pleural cavities had facilitated the rapid progression of tumor and the consequent bilateral malignant pleural effusions had made the management of disease much more difficult, leading to the early fatal outcome. To our knowledge, this is the first case of buffalo chest that was associated with bilateral malignant pleural effusions.

    Pleural effusions are common in Hodgkin lymphoma (HL). However, little is known about their prognostic significance. One hundred and ten patients with HL who presented to the University of Rochester from 1 January 2003 to 12 December 2010 were reviewed. Pleural effusions were evaluated on review of diagnostic-quality computed tomography (CT) scans. Pleural effusions were present in 26/110 patients: 1/7 (14%) stage I, 11/61 (18%) stage II, 3/18 (17%) stage III and 11/24 (46%) stage IV, and 25/91 (27%) patients had mediastinal involvement, 16/38 (42%) patients had extranodal involvement (any) and 5/14 (35%) patients had E lesions (direct extension to extranodal tissue). Unilateral and bilateral pleural effusions were equally prevalent. Survival analysis demonstrated decreased overall survival for patients with pleural effusions of borderline significance for stage I-IV (p = 0.055) but failed to show significance for patients with stage I-III (p = 0.115). Increasing stage, any extranodal involvement and bulky mediastinal disease were each predictive of pleural effusions. The presence of pleural effusion at presentation may be predictive of inferior survival for patients with Hodgkin lymphoma.

    We present a case of bilateral lesions in a 50-year-old man, which were on first impression mistaken for and initially treated as bilateral cellulitis. We propose that bilateral cellulitis, as opposed to unilateral, is rare and that other aetiologies should be considered in evaluating a patient with bilateral lesions. The differential diagnosis includes stasis-dermatitis, lipodermatosclerosis, lymphoedema and vascular lesions such as Kaposi sarcoma, as was identified in this case. Early consultation with dermatology and biopsy in unclear cases mitigates the unnecessary use of prolonged antibiotics, antibiotic resistance and Clostridium difficile infections. HIV testing is an essential screening test in all adults who present with non-specific viral symptoms and rash.

    We report a case of a frail 82-year-old man with seronegative rheumatoid arthritis and a recent pacemaker insertion, admitted with pulmonary oedema and a symptomatic pericardial effusion. He was treated with diuretics and an urgent pericardiocentesis, a sample from which cultured Enterobacter cloacae. A subsequent abdominal CT scan revealed faecal loading, an abnormal anorectal canal and sigmoid colon and a bowel perforation. Endoscopy, biopsies and histopathology confirmed a diagnosis of cytomegalovirus (CMV) colitis with coexistent fungal infection. The E. cloacae infection was successfully treated with 6 weeks of intravenous meropenem, while the CMV and fungal infections were treated with a combination of valganciclovir and fluconazole. We postulate that the bowel perforation resulted from a combination of CMV colitis, faecal loading and steroid therapy and led to bacterial translocation of E. cloacae and the development of the pericardial effusion. This case represents an unusual pathophysiology for the development of an E. cloacae pericardial effusion. PMID:25697299

    Eruption disorders are numerous varying from delayed to complete failure of eruption. Primary failure of eruption (PFE) is a rare condition that involves arrested eruption of teeth with the absence of local or general contributory factors. Another rare and clinically challenging phenomenon is canine transmigration which is the intra-osseous movement of impacted canines across the midline. This report presents the first case of combined failure of eruption of multiple teeth with bilateral mandibular canine transmigration, transposition of upper canine and the first premolar, torus palatinus, and class III incisor relationship in a 33-year-old asymptomatic and nonsyndromic female patient.

    A panel of tumour markers including carcinoembryonic antigen (CEA), carbohydrate antigen (Ca)15-3, Ca125 and Ca19-9 were measured in the lysate of sediments and in the supernatants of pleural effusions of patients with benign and malignant disease. The tumour markers were also measured in the serum of the same patients. Of these patients, 32 had benign diseases (12 trasudative effusions associated with cirrhosis and 20 with non-malignant exudates: 12 pleuritis and 8 other inflammations) and 103 had malignant effusions (37 breast cancers, 29 lung cancers, 10 ovary cancers, 6 kidney cancers, 11 mesotheliomas and 10 lymphomas). We showed the highest level of CEA in pleural effusions of lung cancer followed by that in pleural effusions of breast cancer; whereas Ca15-3 was very high in the pleural effusions of breast and lung cancer. Concerning the lysate of sediment, CEA was high in the pleural effusions of patients with lung cancer and Ca15-3 in those of patients with breast cancer. The other markers are much less useful. For the remaining tumours, none of the markers tested appear to aid in the diagnosis of disease. In conclusion, our data suggest that the combined determination of tumour markers on supernatants and sediments of pleural effusion may provide additional information on the nature of pleural effusion, especially for cases with negative cytology.

    Bagana volcano (Bougainville Island, Papua New Guinea) has exhibited nearly continuous extrusion of andesitic lava for over a century, but has largely been studied by satellite remote sensing. Satellite UV spectroscopy has revealed Bagana to be among the largest volcanic sources of sulfur dioxide worldwide. Satellite radar measurements of lava extrusion rate suggest that the entire edifice could have been built in only a few centuries. Bagana is dominantly constructed from lava flows, but also exhibits violent PDC-forming explosive eruptions, which threaten local populations.We present new multi-parameter data from fieldwork on Bagana in September 2016. UV spectrometers were deployed to ground-truth satellite observations of SO2 emissions, and track sub-daily variations in gas output. In situ measurements and sampling of emissions provide the first gas composition data for this volcano. Aerial imagery filmed by UAV was obtained to generate a high resolution DEM of the edifice for use in calibrating ongoing satellite radar studies of deformation and extrusion rate. Lava and tephra samples were gathered, with the aim of comparing melt composition and volatile content between eruptions of different style. The combination of gas geochemistry, geophysical monitoring from space, and petrology will be used to build a model framework to understand the pulsatory nature of Bagana's lava extrusion, and transitions to explosive activity.A campaign to a continuously active but poorly-studied volcano affords many opportunities for education and outreach. The campaign participants included early career scientists from five countries, who planned and carried out the fieldwork and exchanged expertise in a range of techniques. All work was undertaken in close collaboration with Rabaul Volcano Observatory, and was informed by their strategic monitoring goals, a valuable experience for the field team of synergising research activities with more operational concerns.

    The commonly utilized phosphodiesterase type 5 inhibitors do not lead to satisfactory penile erection after radical prostatectomy mainly because of insufficient nitric oxide drive from the damaged cavernous nerves. The aim of this study was to assess the efficacy and mechanisms of icariin in combination with daily sildenafil on neurogenic erectile dysfunction and penile atrophy in a rat model of bilateral cavernous nerves injury. Sixty male Sprague-Dawley rats injected with 5-ethynyl-2-deoxyuridine (50 mg/kg) at postnatal day 1 for the purpose of tracking endogenous stem cells in penis. Forty-eight rats of bilateral cavernous nerves injury were randomized equally into gavage feeding of vehicle, sildenafil (10 mg/kg), icariin (1.5 mg/kg) and sildenafil + icariin, respectively. Twelve sham-operated rats served as control. The intracavernous pressure and mean arterial pressure was measured and mid-penile cross sections were histologically examined 5 weeks after surgery. Western blotting of cavernous tissue protein was also performed. Animals treated with sildenafil + icariin had significantly higher mean intracavernous pressure/mean arterial pressure ratio relative to other rats with bilateral cavernous nerves injury (p < 0.05). The circumference and mean cross-sectional area of the paired corpus cavernosum were effectively preserved in the sildenafil + icariin. Treatment with sildenafil + icariin significantly increased the cavernous cyclic guanosine monophosphate concentration compared with the icariin group (p < 0.05). In addition, the numbers of neuronal nitric oxide synthase-positive nerves and 5-ethynyl-2-deoxyuridine-positive cells co-expressing S100 in the icariin-treated groups were greater compared with the bilateral cavernous nerves injury control group (p < 0.05). These data suggest that the combined use of icariin and daily sildenafil holds promise as a potential therapy for neurogenic erectile dysfunction in the future. The underlying

    To characterize the audiological features in the infants with otitis media with effusion (OME) and to investigate the utility of variety of objective audiometry methods in diagnosis and intervention on OME. Fifty six infants (40 males and 16 females) were investigated, who were referred to our clinic at the General Hospital of Chinese People's Liberation Army by the other hospitals from December 2004 to June 2007 when the infants were diagnosed or highly suspected of OME. The ages at the initial diagnosis ranged from 42 days to three years, with an average of five months. The infants, after receiving the conventional otolaryngological exams, were subjected to the tests of auditory brainstem response (ABR), otoacoustic emission (OAE), tympanometry (226 Hz and 1000 Hz) and behaviors audiometry. Among 56 affected infants, 87 ears were diagnosed with OME, of which 31 infants were affected bilateral and 25 with monaural. For the 49 infants who received hearing screening at birth, 36 infants were referred at the initial screening. For the 52 infants who received repeated screening, all subjects were referred. Six infants without receiving hearing screening came to clinic when their parents observed their kids' hearing impairment. Among the 52 cases (104 ears) who received tympanometry test, 20 subjects (28 ears) showed B or C type tympanometry curve. Thirty-nine cases (78 ears) were given tympanometry test at 1000 Hz, of which 38 cases (55 ears) showed abnormal hearing. Among 56 infants (112 ears) with ABR test, 49 subjects (74 ears) exhibited prolonged ABR type I curve. All 56 infants (112 ears) received OAE test, of which 55 subjects (81 ears) were referred. Four infants (8 ears) accepted the behavior test and all of them showed A-B Gap. The combined tympanometry test at both 226 Hz and 1000 Hz, ABR latency or threshold test, infant's behavior test and OAE, used jointly, enable characterizing better OME in infants, thus helping early diagnosis of this hearing disorder.

    Bilious pleural effusion is an extremely rare condition associated with liver diseases, subphrenic or subhepatic abscess formation, biliary peritonitis, and invasive procedures (i.e., percutaneous biliary drainage or liver biopsy). The current diagnostic test is based on the measurement of the ratio of pleural total bilirubin to serum total bilirubin, which is greater than 1 in patients with bilious pleural effusion. Given the low incidence of bilious pleural effusion, the precise diagnostic yield of this ratio based test has not been evaluated. We retrospectively reviewed the medical records of our institution and searched the PubMed database for reports of bilious pleural effusion. We identified a total of 12 cases of bilious pleural effusion (9 from 8 Pubmed reports and 3 from our institutional records). The factors causing this condition were broadly classified into three categories based on the pathophysiology: 1) liver diseases (echinococcosis, tuberculosis and amebiasis); 2) subhepatic/subphrenic abscess or biliary peritonitis, with or without biliary tract obstruction; and 3) iatrogenic disease after percutaneous biliary drainage and/or liver biopsy. The sensitivity of detection was 76.9% when the ratio of pleural total bilirubin to serum total bilirubin was greater than 1. The sensitivity increased to 100% when a combination test including pleural glycoholic acid was adopted. This study demonstrates the high diagnostic yield for bilious pleural effusion using a combination of two test criteria; a ratio of pleural total bilirubin to serum total bilirubin greater than 1 and the presence of pleural glycoholic acid.

  20. Bilateral vestibulopathy.

    PubMed

    Strupp, M; Feil, K; Dieterich, M; Brandt, T

    2016-01-01

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    2015-07-01

    Pleural effusions have a major impact on the cardiorespiratory system. This article reviews the pathophysiological effects of pleural effusions and pleural drainage, their relationship with breathlessness, and highlights key knowledge gaps. The basis for breathlessness in pleural effusions and relief following thoracentesis is not well understood. Many existing studies on the pathophysiology of breathlessness in pleural effusions are limited by small sample sizes, heterogeneous design and a lack of direct measurements of respiratory muscle function. Gas exchange worsens with pleural effusions and improves after thoracentesis. Improvements in ventilatory capacity and lung volumes following pleural drainage are small, and correlate poorly with the volume of fluid drained and the severity of breathlessness. Rather than lung compression, expansion of the chest wall, including displacement of the diaphragm, appears to be the principle mechanism by which the effusion is accommodated. Deflation of the thoracic cage and restoration of diaphragmatic function after thoracentesis may improve diaphragm effectiveness and efficiency, and this may be an important mechanism by which breathlessness improves. Effusions do not usually lead to major hemodynamic changes, but large effusions may cause cardiac tamponade and ventricular diastolic collapse. Patients with effusions can have impaired exercise capacity and poor sleep quality and efficiency. Pleural effusions are associated with abnormalities in gas exchange, respiratory mechanics, respiratory muscle function and hemodynamics, but the association between these abnormalities and breathlessness remains unclear. Prospective studies should aim to identify the key mechanisms of effusion-related breathlessness and predictors of improvement following pleural drainage.

    In a case-control study asbestos exposure in 64 consecutive men with idiopathic pleural effusion and 129 randomly sampled age matched male controls was compared. Furthermore, seven women and 64 men with idiopathic pleural effusion were studied, including a three year re-examination, in an attempt to identify characteristics that might distinguish asbestos exposed from non-exposed patients. Asbestos exposure was significantly (p less than 0.01) more frequent in men with idiopathic effusions than in controls. The idiopathic effusions seen in asbestos exposed patients were compatible with the diagnosis "asbestos pleural effusion." Two features were characteristic of patients with asbestos pleural effusion: a chest radiograph at the initial examination showing converging pleural linear structures or rounded atelectasis or a history of recurrent pleural effusion, or both.

    Perirenal fluid accumulation has been described as an ultrasonographic feature of urine leakage, hemorrhage, abscessation, or neoplasia. The purpose of this retrospective study was to report perirenal effusion as an additional ultrasonographic finding in canine and feline patients with acute renal failure. The causes of acute renal failure in 18 patients included nephrotoxicity (4), leptospirosis (3), ureteral obstruction (2), renal lymphoma (2), ureteronephrolithiasis (2), prostatic urethral obstruction (1) and interstitial nephritis and ureteritis (1). An underlying cause was not identified in three patients. The sonographic finding of perirenal fluid was bilateral in 15 patients. Unilateral perirenal fluid was identified ipsilateral to the site of ureteric obstruction in two patients. Large effusions extended into the caudal retroperitoneal space. Additional sonographic findings suggestive of renal parenchymal disease included mild (5), moderate (5) or severe (2) pyelectasia, increased renal echogenicity (11), increased (9) or decreased renal size (2) and ureteral and/or renal calculi (3). There did not appear to be an association between the volume of perirenal fluid and the severity of renal dysfunction. All patients with large effusions underwent euthanasia. Perirenal fluid developing in acute renal failure is thought to be an ultrafiltrate associated with tubular back-leak into the renal interstitium that overwhelms lymphatic drainage within the perirenal and retroperitoneal connective tissues although obstruction to urine flow may also play a role. Localized perirenal retroperitoneal free fluid may be a useful ultrasonographic feature to assist with the characterization of, and determination of prognosis in, patients with suspected renal disease.

    Abstract Background: Resection of the liver is often limited to the insufficient future liver remnant (FLR). To address this problem, the modification surgical technique “associating liver tourniquet and portal vein occlusion for staged hepatectomy” (ALTPS) was developed and led to quick hypertrophy in a short interval. In some colorectal cancer patients with multiple and bilobar metastases, the resection of the primary is often protracted immensely to the unpredictable postoperative complications for whom is to be treated with a liver-first approach. To overcome this problem, a simultaneous resection of the primary tumor and totally laparoscopic ALTPS for bilateral liver metastases of the primary colon cancer were performed. Case summary: A 63-year-old female patient with left colon cancer and synchronous bilateral colorectal liver metastases underwent a totally laparoscopic ALTPS and simultaneous left hemicolectomy because of the small FLR. The operative times were 460 minutes for the first stage and 240 minutes for the second stage without the need for blood transfusions. The recoveries after the first and the second operations were uneventful, and the patient was discharged on postoperative day 11 of the second stage operation. Conclusion: Our case shows the totally laparoscopic ALTPS and simultaneous left hemicolectomy at step 1 for bilobar liver metastases of the primary colon cancer with no severe postoperative complications. If a resection of the primary tumor does not compromise the split procedure, the combination of pure laparoscopic ALTPS and primary resection is feasible and safe. PMID:28296776

    An experience with 216 bilateral hernias in female patients is reviewed. The condition is rare, occurring only once in every 250 patients admitted for a hernia repair. Bilateral primary indirect inguinal hernias were the most frequent type. Bilateral primary femoral hernias were quite rare while bilateral primary direct inguinal hernias were even more uncommon. Other rare bilateral combinations are briefly described. The incidence in children is given. Etiological factors are discussed, emphasizing the strong posterior wall of the inguinal canal in females. Two per cent of patients developed a recurrent hernia; one per cent of hernias recurred. No recurrence following a bilateral primary indirect inguinal hernia repair and no “femoral” recurrence following inguinal repair were recorded. PMID:5348491

    Background Breast cancer is the second most common etiologic cause in malignant pleural effusions (MPE). The aim of this study was to investigate the efficacy of long term pleural catheters in inducing self sclerosis in pleural effusions of breast cancer patients. Methods In this study, 26 patients with breast cancer relapleural effusions that occurred between January 2011 and July 2013, who were considered not to undergo any other treatments and managed with prolonged pleural catheters (Jackson-Pratt silicone flat drain), were retrospectively analyzed. Thirty pleural catheters were inserted in 26 patients. All patients were female, mean age was 52 (range, 37-66) years old. Drainage over 1,500 mL per day was not allowed in order to avoid a lung edema. The catheters were removed in patients who had restoration of lung expansion and drainage under 50 mL/day. Results The histologic subtypes in pleural effusions were invasive ductal carcinoma in 18 patients, ductal carcinoma in situ in 4, invasive lobular carcinoma in 2, tubular carcinoma in 1, and medullary carcinoma in 1. Three of the 26 patients underwent bilateral catheter insertion, and one patient underwent a reinsertion of the catheter into the same hemithorax due to a recurrence. The catheters were retained for a mean period of 18 days (range, 11-38 days). In one patient with invasive ductal carcinoma and paramalignant pleural effusion (PMPE) (3.8%), a recurrent pleural effusion was seen 34 days after removal of the catheter. There were no complications. One patient died while the catheter was in place. Conclusions Prolonged catheters for the management of pleural effusions in selected patients have become more popular than other treatment alternatives due to a shorter length of stay and lower costs. We recommend the use of Jackson Pratt (JP) silicone flat drains which in our opinion provide effective pleurodesis in addition to easy application in recurrent effusions caused by breast cancer.

    Hepatic hydrothorax is the paradigmatic pleural effusion in liver cirrhosis. It is defined as a pleural effusion in a patient with portal hypertension and no cardiopulmonary disease. The estimated prevalence of this complication in patients with liver cirrhosis is 5 to 6%. Its pathophysiology involves movement of ascitic fluid from the peritoneal cavity into the pleural space through diaphragmatic defects. Thoracentesis and pleural fluid analysis are necessary for diagnosis. Initial management consists of sodium restriction, diuretics, and therapeutic thoracentesis. A transjugular intrahepatic portosystemic shunt may provide a bridge prior to liver transplantation. Spontaneous bacterial empyema is the infection of a preexisting hydrothorax. The more frequent bacteria involved are ENTEROBACTERIACEAE and gram-positive cocci. Antibiotic therapy is the cornerstone of therapy. This article reviews etiology, clinical manifestations, and therapy of these two complications of liver cirrhosis and portal hypertension.

    Abstract Background: Patients on antiplatelet therapy following percutaneous coronary intervention can become coagulopathic due to infection. Performing regional anesthesia for bilateral surgery in such cases is challenging. We report a case of successful combined inguinal femoral and subgluteal sciatic nerve blocks (CFSNBs) for simultaneous bilateral below-knee amputations in a coagulopathic patient on antiplatelet therapy. Methods: A 70-year-old male patient presented with pain in both feet due to diabetic foot syndrome. The condition could not be managed by open amputations of the toes at the metatarsal bones and subsequent antibiotic therapy. Computed tomographic angiography showed significant stenosis in the arteries supplying the lower limbs, indicating atherosclerotic gangrene in both feet. Balloon angioplasty and bypass surgery with subsequent debridements with application of negative-pressure wound therapy and additional open amputations did not improve the patient's clinical condition: his leukocyte counts and C-reactive protein levels were above the normal range, and his prothrombin and activated partial thromboplastin times were increased. Results: Simultaneous bilateral below-knee amputations were performed under ultrasound-guided CFSNBs. Following left CFSNBs using 45 mL of a local anesthetic mixture (1:1 ratio of 1.0% mepivacaine and 0.75% ropivacaine), the left below-knee amputation was performed for 76 minutes. Subsequently, under right CFSNBs using 47 mL of the local anesthetic mixture, the right below-knee amputation proceeded for 85 minutes. Throughout each surgery, dexmedetomidine was continuously administered, and a sensory blockade was well maintained in both limbs. The patient did not complain of pain due to regression of the first CFSNBs during the second surgery. The CFSNBs successfully prevented tourniquet pain.

    Infrared emission from an active effusive volcanic eruption on Surtsey, Vestmannaeyjar, Iceland, was recorded by airborne and satellite infrared systems at irregular intervals between 19 August and 3 October 1966. Ground and lava temperature measurements and volumetric lava outflow data permitted a comparison to be made between total thermal-energy yield and radiant emission recorded by the satellite system. The Nimbus HRIR recorded radiant emission at a level of about 3% of the estimated total thermal yield.

  12. Pericardial Effusion and Pericardiocentesis: Role of Echocardiography

    PubMed Central

    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

    Mutations in the recently described RARS2 gene encoding for mitochondrial arginyl-transfer RNA synthetase give rise to a disorder characterised by early onset seizures, progressive microcephaly and developmental delay. The disorder was named pontocerebellar hypoplasia type 6 (PCH6) based on the corresponding radiological findings observed in the original cases. We report two siblings with the RARS2 mutation who displayed typical clinical features of PCH6, but who had distinct neuroimaging features. Early scans showed marked supratentorial, rather than infratentorial, atrophy, and the pons remained preserved throughout. One sibling also had bilateral subdural effusions at presentation. The deceleration in head growth pointed to an evolving genetic/metabolic process giving rise to cerebral atrophy and secondary subdural effusions. RARS2 mutations should be considered in infants presenting with seizures, subdural effusions, decelerating head growth and evidence of cerebral atrophy even in the absence of pontocerebellar hypoplasia on imaging.

    Polymyalgia rheumatica is an inflammatory rheumatic disease that presents with bilateral pain and stiffness affecting mainly proximal muscles. It affects individuals over 50 years of age and it is usually associated with a raised erythrocyte sedimentation rate. Classically, treatment with low-dose corticosteroids results in a dramatic improvement in both symptoms and laboratory findings. We report the case of an 80 years old patient presenting polymyalgia rheumatica coinciding with pleuropericardial effusion. The patient had a very good response to treatment with rapid improvement in the symptomatology and laboratory findings. Polymyalgia Rheumatica is a common disease but it is rarely associated to pleuropericardial effusion. It should be considered in the differential diagnostic in patients presenting with pericardial effusion over 50 of age years due to the good response to treatment.

    Parapneumonic pleural effusions (PPE) are a relatively common (5-40%) complication of paediatric pneumonia. However, in clinical practice the majority of the effusions are small and do not need any further investigation or specific treatment apart from antibiotic therapy. A small number require drainage or surgical intervention. Rarely, significant effusions are associated with non-bacterial pneumonia in the paediatric population. Pleural tuberculosis in our hospital is the second highest cause of pleural effusions related to the high incidence of TB in our city. In the last 3 years we have had around 50 cases of pleural TB in children. Copyright © 2015. Published by Elsevier Ltd.

    Parapneumonic pleural effusions represent the main cause of pleural infections. Their incidence is constantly increasing. Although by definition they are considered to be a "parapneumonic" phenomenon, the microbial epidemiology of these effusions differs from pneumonia with a higher prevalence of anaerobic bacteria. The first thoracentesis is the most important diagnostic stage because it allows for a distinction between complicated and non-complicated parapneumonic effusions. Only complicated parapneumonic effusions need to be drained. Therapeutic evacuation modalities include repeated therapeutic thoracentesis, chest tube drainage or thoracic surgery. The choice of the first-line evacuation treatment is still controversial and there are few prospective controlled studies. The effectiveness of fibrinolytic agents is not established except when they are combined with DNase. Antibiotics are mandatory; they should be initiated as quickly as possible and should be active against anaerobic bacteria except for in the context of pneumococcal infections. There are few data on the use of chest physiotherapy, which remains widely used. Mortality is still high and is influenced by underlying comorbidities. Copyright © 2014 SPLF.

    Pleural effusion secondary to a nonmalignant cause can represent significant morbidity and mortality. Nonmalignant pleural effusion (NMPE) is common, with congestive heart failure representing the leading cause. Despite this, there are limited data on mortality risk and associated prognostic factors. We recruited 782 consecutive patients presenting to a pleural service between March 2008 and March 2015 with an undiagnosed pleural effusion. Further analysis was conducted in 356 patients with NMPE. Pleural biochemical analysis, cytologic analysis, thoracic ultrasonography, and chest radiography were performed. Echocardiography, CT imaging, radiologically guided biopsy, and medical thoracoscopy were undertaken as clinically indicated. Patients were followed for a minimum duration of 12 months, with the final diagnosis decided through independent review by two respiratory consultants. Of the 782 patients, 356 were diagnosed with NMPE (46%). These patients had a mean age of 68 years (SD, 17 years) with 69% of them being men. Patients with cardiac, renal, and hepatic failure had 1-year mortality rates of 50%, 46%, and 25%, respectively. Bilateral effusions (hazard ratio [HR], 3.55; 95% CI, 2.22-5.68) and transudative effusions (HR, 2.78; 95% CI, 1.81-4.28) were associated with a worse prognosis in patients with NMPE, with a 57% and 43% 1-year mortality rate, respectively. This is the largest prospectively collected series in patients with NMPE, demonstrating that cases secondary to organ dysfunction have extremely high 1-year mortality. In addition, the presence of bilateral and transudative effusions is an indicator of increased mortality. Clinicians should be aware of these poor prognostic features and guide management accordingly. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

    Our previous study demonstrated that superoxide dismutase levels were higher in tuberculous pleural effusions than in malignant pleural effusions, but that this difference could not be used to discriminate between the two. The objective of the present study was to investigate the levels of superoxide dismutase 2 in pleural effusions and to evaluate the diagnostic significance of pleural effusion superoxide dismutase 2. Superoxide dismutase 2 concentrations were determined in pleural effusions from 54 patients with tuberculous pleural effusion and 33 with malignant pleural effusion using an enzyme-linked immunosorbent assay (ELISA) kit. Pleural effusion interferon gamma and tumor necrosis factor alpha levels were also analyzed by ELISA. The Mann-Whitney U test was used to evaluate the significance of differences. Associations between superoxide dismutase 2 concentrations and sex, age and smoking habits were assessed using Spearman's or Pearson's correlation coefficient analysis. Receiver operator characteristic analysis was performed to evaluate the value of superoxide dismutase 2 levels in the discrimination of tuberculous pleural effusion from malignant pleural effusion. Superoxide dismutase 2 levels were significantly higher in patients with tuberculous pleural effusion compared with those with malignant pleural effusion (p<0.05). When superoxide dismutase 2 was used to differentiate between tuberculous pleural effusions and malignant pleural effusions, the area under the receiver operator characteristic curve was 0.909 (95% confidence interval, 0.827-0.960; p<0.01). With a cut-off value of 54.2 ng/mL, the sensitivity, specificity, positive likelihood ratio and negative likelihood ratio were 75.8% (95%CI: 57.7-88.9%), 98.1% (95%CI: 90.1-99.7%), 40.91 and 0.25, respectively. Furthermore, significant correlations between pleural effusion superoxide dismutase 2 and interferon gamma (r=0.579, p<0.01) and between pleural effusion superoxide dismutase 2 and tumor

    Objective To compare the efficacy of three surgical treatment combinations - myringotomy and tympanostomy tube insertion (M&T), adenoidectomy with M&T (A-M&T), and adenoidectomy with myringotomy (A-M) - in reducing middle ear disease in young children with chronic OME. Methods Children 24–47 months of age, with a history of bilateral middle-ear effusion (MEE) for at least 3 months, unilateral for 6 months or longer or unilateral for 3 months after extrusion of a tympanostomy tube, unresponsive to recent antibiotic, were randomly assigned to either M&T, A-M&T, or A-M. Treatment assignment was stratified by age (24–35 months, 36–47 months), nasal obstruction (no, yes) and previous history of M&T (no, yes). Subjects were followed monthly and with any signs or symptoms of ear disease for up to 36 months. Results Ninety-eight subjects were randomly assigned to the 3 treatment groups. Fifty-six subjects (57%) were 24–35 months of age; 63% had nasal obstruction, and 36% had previously undergone M&T. During the 36 months after entry, subjects were noted to have MEE for the following percentages of time: 18.6% in the M&T group, 20.6% in the A-M&T group, and 31.1% in the A-M group (M&T vs A-M&T, p=.87; M&T vs A-M, p=.01). By 36 months, there were no differences in the number of further surgical procedures for ear disease needed among the groups. Conclusions Adenoidectomy with or without tube insertion provided no advantage to young children with chronic OME in regard to time with effusion compared to tube insertion alone. Fewer tympanostomy tubes were placed in children undergoing A-M as their initial procedure, but this should be balanced by the performance of the more invasive surgical procedure and their increased time with effusion.

    To establish a method (negative enrichment by immunomagnetic beads) for detection of tumor cells in pleural effusions and to evaluate the sensitivity and specificity of the method for clinical application. Five, 10, 20, 50 and 100 A549 (lung adenocarcinoma) cells were labeled with DAPI and added into 20 ml pleural effusions [containing (1 - 10)×10(6)cells] from heart failure patients, followed by immunomagnetic negative enrichment method. Recovered cancer cells were enumerated using a fluorescent microscope. Tumor cells were enriched from pleural effusion samples by means of density gradient centrifugation and negative enrichment by immunomagnetic beads method, followed by identification with cytology analysis (Wright's Giemsa's staining), immunofluorescence staining (IF) and fluorescence in situ hybridization (FISH) using centromere DNA probes of chromosome 7 and 8. Cytology, IF and FISH evaluations were performed in 53 pleural effusion samples, including 36 cases of malignant disease (25 male and 11 female patients aging 40 to 78 years, mean age (63 ± 9) and 17 cases of benign disease (8 male and 9 female patients aging 25 to 81 years, mean age (53 ± 18). After DAPI staining and mixing with pleural effusions from heart failure patients, the cell recovery rates of A549 cells evaluated under fluorescence microscope were 75%, 78%, 82%, 85%, 88%, and the average recovery rate was 81.6%.

The aim of the present study was to challenge the ability of SVV, PPV and GEDV to predict fluid responsiveness in a porcine model with pleural effusions. Pigs were studied at baseline and after fluid loading with 8 ml kg(-1) 6% hydroxyethyl starch. After withdrawal of 8 ml kg(-1) blood and induction of pleural effusion up to 50 ml kg(-1) on either side, measurements at baseline and after fluid loading were repeated. Cardiac output, stroke volume, central venous pressure (CVP) and pulmonary occlusion pressure (PAOP) were obtained by pulmonary thermodilution, whereas GEDV was determined by transpulmonary thermodilution. SVV and PPV were monitored continuously by pulse contour analysis. Pleural effusion was associated with significant changes in lung compliance, peak airway pressure and stroke volume in both responders and non-responders. At baseline, SVV, PPV and GEDV reliably predicted fluid responsiveness (area under the curve 0.85 (p<0.001), 0.88 (p<0.001), 0.77 (p = 0.007). After induction of pleural effusion the ability of SVV, PPV and GEDV to predict fluid responsiveness was well preserved and also PAOP was predictive. Threshold values for SVV and PPV increased in presence of pleural effusion. In this porcine model, bilateral pleural effusion did not affect the ability of SVV, PPV and GEDV to predict fluid responsiveness.

We report a case of pulmonary Mycobacterium kansasii infection with pleural effusion, distinguished from pulmonary tuberculosis. A 44-year-old man presented to a clinic with a productive cough, sputum, and loss of appetite for several months. Chest X-ray and chest computed tomography (CT) showed right pleural effusion, centrilobular nodules and infiltrative shadows with cavities in the bilateral lung fields. The direct smear examination showed positive acid-fast bacilli (Gaffky 5). He was referred to our hospital for suspected recurrent pulmonary tuberculosis. We started anti-tuberculosis drugs because pulmonary tuberculosis complicated with pleurisy was first suspected from the findings of high ADA level (78.6 IU/l) of the effusion and positive result of interferon-gamma release assay (QuantiFERON TB-2G). But Mycobacterium tuberculosis and M. avium complex was not identified by the polymerase chain reaction method and the culture of the sputum was negative. At a later date, Mycobacterium kansasii was detected by sputum culture. The patient was diagnosed as pulmonary Mycobacterium kansasii infection and treatment with anti-tuberculosis drugs including RFP resulted in a good clinical response. This case was a rare case of pulmonary Mycobacterium kansasii infection with pleural effusion, distinguished from pulmonary tuberculosis.

    A patient with rheumatoid arthritis (RA) and chronic obstructive lung disease was admitted with respiratory failure due to a massive pleural effusion. An extensive evaluation proved the effusion to be of rheumatoid origin. The effusion resolved with prednisone and penicillamine therapy. Although pleural effusions associated with RA are common, massive effusions are rare and respiratory failure from a rheumatoid pleural effusion has not been reported.

    Background There are no firm recommendations when cytology should be performed in pleural transudates, since some malignant pleural effusions (MPEs) behave biochemically as transudates. The objective was to assess when would be justified to perform cytology on pleural transudates. Methods Consecutive patients with transudative pleural effusion (PE) were enrolled and divided in two groups: malignant and non-MPE. Logistic regression analysis was used to estimate the probability of malignancy. Two prognostic models were considered: (I) clinical-radiological variables; and (II) combination of clinical-radiological and analytical variables. Calibration and discrimination [receiver operating characteristics (ROC) curves and area under the curve (AUC)] were performed. Results A total of 281 pleural transudates were included: 26 malignant and 255 non-malignant. The AUC obtained with Model 1 (left PE, radiological images compatible with malignancy, absence of dyspnea, and serosanguinous appearance of the fluid), and Model 2 (the variables of Model 1 plus CEA) were 0.973 and 0.995, respectively. Although no false negatives are found in Models 1 and 2 to probabilities of 11% and 14%, respectively, by applying bootstrapping techniques to not find false negatives in 95% of other possible samples would require lowering the cut-off points for the aforementioned probabilities to 3% (Model 1) and 4% (Model 2), respectively. The false positive results are 32 (Model 1) and 18 (Model 2), with no false negatives. Conclusions The applied models have a high discriminative ability to predict when a transudative PE may be of neoplastic origin, being superior to adding an analytical variable to the clinic-radiological variables.

    A pleural effusion is an excessive accumulation of fluid in the pleural space. It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to a systemic disorder. Patients most commonly present with dyspnea, initially on exertion, predominantly dry cough, and pleuritic chest pain. To treat pleural effusion appropriately, it is important to determine its etiology. However, the etiology of pleural effusion remains unclear in nearly 20% of cases. Thoracocentesis should be performed for new and unexplained pleural effusions. Laboratory testing helps to distinguish pleural fluid transudate from an exudate. The diagnostic evaluation of pleural effusion includes chemical and microbiological studies, as well as cytological analysis, which can provide further information about the etiology of the disease process. Immunohistochemistry provides increased diagnostic accuracy. Transudative effusions are usually managed by treating the underlying medical disorder. However, a large, refractory pleural effusion, whether a transudate or exudate, must be drained to provide symptomatic relief. Management of exudative effusion depends on the underlying etiology of the effusion. Malignant effusions are usually drained to palliate symptoms and may require pleurodesis to prevent recurrence. Pleural biopsy is recommended for evaluation and exclusion of various etiologies, such as tuberculosis or malignant disease. Percutaneous closed pleural biopsy is easiest to perform, the least expensive, with minimal complications, and should be used routinely. Empyemas need to be treated with appropriate antibiotics and intercostal drainage. Surgery may be needed in selected cases where drainage procedure fails to produce improvement or to restore lung function and for closure of bronchopleural fistula. PMID:27147861

    Each year in the United States an estimated 1.5 million people develop pleural effusions and approximately 178,000 thoracenteses (12%) are performed. While it has been established that malignant effusions are associated with increased mortality, the association between mortality and all-cause pleural effusions in a medical population has not been previously evaluated. Our objective was to evaluate associations between 30-day and 12-month all-cause mortality among patients with a pleural effusion. All patients admitted to the medical service at Yale-New Haven Hospital during March 2011 were screened for pleural effusion. Pleural effusions were documented by the attending radiologist and the medical record was reviewed for admitting diagnosis, severity of illness and whether a thoracenteses was performed. The outcomes were 30-day and 12-month mortality after identification of the pleural effusion. One-hundred and four patients admitted to the medical service had pleural effusions documented by the attending radiologist. At 30-days, 15% of these patients had died and by 12-months mortality had increased to 32%. Eleven (10.6%) of the 104 patients underwent a thoracenteses. Severity of illness and malignancy were associated with 30-day mortality. For 12-month mortality, associations were found with age, severity of illness, malignancy, and diagnosis of pulmonary disease. Although sample size precluded statistical significance with mortality, the hazard ratio for thoracenteses and 30-day mortality was protective, suggesting a possible short term survival benefit. In hospitalized medical patients with a pleural effusion, age, severity of illness and malignancy or pulmonary disease were associated with higher 12-month mortality. Thoracenteses may provide a protective effect in the first 30 days, but larger studies are needed to detect a short-term survival benefit. The presence of a pleural effusion indicates a high risk of death, with 15% of patients dying within 30 days

    Objective: Pleural effusion is common problem, but the rapid and reliable diagnosis for specific pathogenic effusions are lacking. This study aimed to identify the diagnosis based on clinical variables to differentiate pleural tuberculous exudates from other pleural effusions. We also investigated the role of renin-angiotensin system (RAS) and matrix metalloproteinase (MMPs) in the pathogenesis of pleural exudates. Experimental design: The major components in RAS and extracellular matrix metabolism, including angiotensin converting enzyme (ACE), ACE2, MMP-2 and MMP-9 activities, were measured and compared in the patients with transudative (n = 45) and exudative (n = 80) effusions. The exudative effusions were come from the patients with tuberculosis (n = 20), pneumonia (n = 32), and adenocarcinoma (n = 28). Results: Increased ACE and equivalent ACE2 activities, resulting in a significantly increased ACE/ACE2 ratio in exudates, were detected compared to these values in transudates. MMP-9 activity in exudates was significantly higher than that in transudates. The significant correlation between ACE and ACE2 activity that was found in transudates was not found in exudates. Advanced analyses showed significantly increased ACE and MMP-9 activities, and decreased ACE2 activity in tuberculous pleural effusions compared with those in pneumonia and adenocarcinoma effusions. The results indicate that increased ACE and MMP-9 activities found in the exudates were mainly contributed from a higher level of both enzyme activities in the tuberculous pleural effusions. Conclusion: Interplay between ACE and ACE2, essential functions in the RAS, and abnormal regulation of MMP-9 probably play a pivotal role in the development of exudative effusions. Moreover, the ACE/ACE2 ratio combined with MMP-9 activity in pleural fluid may be potential biomarkers for diagnosing tuberculous pleurisy. PMID:23091417

    We report a case of aorto-iliac occlusion due to descending aortic dissection treated initially with femoro-femoral cross-over bypass and secondarily with unilateral aorto-iliac stenting because of progression of the dissection. A 75-year-old man presented with acute ischemia of the right leg. CT revealed occlusion of the right iliac artery due to descending aortic dissection with a clotted false lumen. Three days after femoro-femoral cross-over bypass,ischemia of both legs developed and angiography demonstrated occlusion of the infrarenal aorta and left common iliac artery. Two overlapping stents were deployed in these vessel segments. Completion angiography confirmed successful recanalization with adequate distal flow and good patency of the cross-over bypass. Peripheral pulses were restored and the patient's symptoms were alleviated. Combined treatment with cross-over bypass and endovascular recanalization may be considered as a viable alternative to open aortic surgery in selected cases of complicated aorto-iliac dissection with bilateral leg ischemia.

    Pericardial effusion is a common finding in everyday clinical practice. The first challenge to the clinician is to try to establish an etiologic diagnosis. Sometimes, the pericardial effusion can be easily related to a known underlying disease, such as acute myocardial infarction, cardiac surgery, end-stage renal disease or widespread metastatic neoplasm. When no obvious cause is apparent, some clinical findings can be useful to establish a diagnosis of probability. The presence of acute inflammatory signs (chest pain, fever, pericardial friction rub) is predictive for acute idiopathic pericarditis irrespective of the size of the effusion or the presence or absence of tamponade. Severe effusion with absence of inflammatory signs and absence of tamponade is predictive for chronic idiopathic pericardial effusion, and tamponade without inflammatory signs for neoplastic pericardial effusion. Epidemiologic considerations are very important, as in developed countries acute idiopathic pericarditis and idiopathic pericardial effusion are the most common etiologies, but in some underdeveloped geographic areas tuberculous pericarditis is the leading cause of pericardial effusion. The second point is the evaluation of the hemodynamic compromise caused by pericardial fluid. Cardiac tamponade is not an “all or none” phenomenon, but a syndrome with a continuum of severity ranging from an asymptomatic elevation of intrapericardial pressure detectable only through hemodynamic methods to a clinical tamponade recognized by the presence of dyspnea, tachycardia, jugular venous distension, pulsus paradoxus and in the more severe cases arterial hypotension and shock. In the middle, echocardiographic tamponade is recognized by the presence of cardiac chamber collapses and characteristic alterations in respiratory variations of mitral and tricuspid flow. Medical treatment of pericardial effusion is mainly dictated by the presence of inflammatory signs and by the underlying disease if

    Malignant pleural effusion (MPE) often presents in patients with cancer at an advanced stage and thus carries a poor prognosis. This review updates the current knowledge on the management of MPE, focusing on recent literature about the efficacy and safety of the most common methods, including pleurodesis by either thoracoscopy with talc insufflation or thoracostomy with talc slurry, use of an indwelling pleural catheter, and intrapleural chemotherapy. Talc remains the agent of choice in pleurodesis, although the use of alternative agents continues to be explored. The choice of procedure to achieve pleurodesis depends on careful patient selection based on predictive factors and individual characteristics. Talc pleuro-desis is relatively well tolerated and safe, as is an indwelling pleural catheter, in an appropriate patient population. Because MPE is a common problem in cancer patients, future research with more randomized, prospective designs and innovative interventions is needed.

    To compare the effects of unilateral and bilateral resistance training on single-leg power output, between-limbs imbalance (BLI), bilateral deficit (BLD), change of direction (COD), and linear sprinting and jumping performance in young elite basketball players. Twenty-two young (U-16-U-19) male basketball players were randomly assigned either to an exclusive unilateral (UNI) (n = 11) or a bilateral (BIL) (n = 11) resistance-training group during a 6-wk period. Both groups training consisted of 3 unilateral or bilateral 90° back-squat sets. A postdetermined number of repetitions was set until power output dropped to <10% of maximum power (MP) output. In addition, both groups performed 2 sets of 5 unilateral or bilateral drop jumps and 2 sets of 5 unilateral or bilateral countermovement jumps (CMJ). Pre- and posttraining, performance was assessed by an incremental bilateral and unilateral squat-load test, a multiple-COD test (V-cut test), a 15-m-sprint test (7.5 + 7.5 m) with one 180° COD performed with both right (180° RCOD) and left (180° LCOD) legs, a 25-m-sprint test (5- and 15-m split time), and a CMJ test. Within-group analyses showed substantial improvements in 180° RCOD, bilateral and unilateral MP, 25-m-sprint test, and CMJ in both groups. Between-groups analyses showed substantially better results in 180° LCOD, MP with right and left legs, BLI, and BLD in UNI than in BIL. Both training programs substantially improved most of the physical-fitness tests, but only UNI reduced between-limbs asymmetry and achieved greater enhancements in actions that mostly required applying force unilaterally in basketball players.

    Mast cells (MCs) have been identified in various tumors; however, the role of these cells in tumorigenesis remains controversial. Here, we quantified MCs in human and murine malignant pleural effusions (MPEs) and evaluated the fate and function of these cells in MPE development. Evaluation of murine MPE-competent lung and colon adenocarcinomas revealed that these tumors actively attract and subsequently degranulate MCs in the pleural space by elaborating CCL2 and osteopontin. MCs were required for effusion development, as MPEs did not form in mice lacking MCs, and pleural infusion of MCs with MPE-incompetent cells promoted MPE formation. Once homed to the pleural space, MCs released tryptase AB1 and IL-1β, which in turn induced pleural vasculature leakiness and triggered NF-κB activation in pleural tumor cells, thereby fostering pleural fluid accumulation and tumor growth. Evaluation of human effusions revealed that MCs are elevated in MPEs compared with benign effusions. Moreover, MC abundance correlated with MPE formation in a human cancer cell–induced effusion model. Treatment of mice with the c-KIT inhibitor imatinib mesylate limited effusion precipitation by mouse and human adenocarcinoma cells. Together, the results of this study indicate that MCs are required for MPE formation and suggest that MC-dependent effusion formation is therapeutically addressable. PMID:25915587

    We report a case of progressive, multifocal melorheostosis in a 28-year-old woman, with involvement of the left arm, chest, spine, and impressive soft tissue involvement. In the past, she had undergone multiple vascular interventions. She presented with spontaneous massive bilateral chylothorax. After conservative treatment without success, we conducted bilateral pleurodesis. This resulted in a clear reduction of pleural effusions, but her medical condition subsequently worsened due to progressive parenchymatous infiltrates, and increased interlobal pleural effusions. She ultimately died of global respiratory insufficiency. In patients with melorheostosis, involvement of the soft tissue can result in distinctive morbidity, and whenever possible, treatment should be conservative.

Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.

    The purpose of this study is to report a systematic observation of uptake or retention of Tc-99m DTPA in pleural effusions and other abnormal states of increased lung water. 24 patients who underwent renal imaging with 10 mCi Tc-99m DTPA were included. Imaging was performed with a large field of view camera for 0-03 minutes after injection and delayed images acquired 2-4 hours later. The images encompassed the mid and lower thorax as well as kidneys. 15 patients showed, at 0-5 minutes, cold areas at lung bases that later showed relatively increased activity at 2-4 hours (hot on delayed images). 14 of these 15 patients showed pleural effusions on chest x-ray. Small bilateral effusions were more clearly demonstrated by scan than by x-ray in 8 of 15 patients. One patient with pneumonia showed an immediate hot area in the infected lobe, and two with pulmonary edema and congestive failure showed diffuse lung retention of Tc-99m on delayed images. Among 9 patients who did not demonstrate abnormal cold or hot areas in their lungs on DTPA images, none had clinical or x-ray evidence of pleural effusion, pneumonia, or congestive failure (100% negative predictive value). Differences in rate constants for diffusion into vs. out of pleural fluid provide a plausible explanation for the observed retention of tracer in effusions, as seen on delayed images. This study indicates that imaging with Tc-99m DTPA provides information of diagnostic value in the detection of pleural effusions. Futhermore, the data suggests that DTPA imaging may also be useful as a simple, cost-effective method to detect other conditions in which regional lung water is abnormally increased.

    Abstract Objective: To report the case of a child with bilateral chylothorax due to infrequent etiology: thoracic duct injury after severe vomiting. Case description: Girl, 7 years old, with chronic facial swelling started after hyperemesis. During examination, she also presented with bilateral pleural effusion, with chylous fluid obtained during thoracentesis. After extensive clinical, laboratory, and radiological investigation of the chylothorax etiology, it was found to be secondary to thoracic duct injury by the increased intrathoracic pressure caused by the initial manifestation of vomiting, supported by lymphoscintigraphy findings. Comments: Except for the neonatal period, chylothorax is an infrequent finding of pleural effusion in children. There are various causes, including trauma, malignancy, infection, and inflammatory diseases; however, the etiology described in this study is poorly reported in the literature. PMID:27178371

    Pleural effusions can be caused by highly different underlying diseases and are characterized by complex interactions of various local and circulating cells as well as numerous soluble parameters like interleukins (IL). Knowledge of this complex network can be helpful in order to make the differential diagnosis in known malignant pleural effusions and understand the underlying immunochemistry of each disease or condition. We investigated immunoreactive concentrations of Interleukin 10 (IL-10) and Interleukin 17 (IL-17) in malignant pleural effusions and peripheral blood from patients with bronchial carcinomas and other carcinomas, excluding other conditions such as congestive heart failure (CHF) and pneumonias in twenty four (24) patients (9 men/15 women), 37-74 years (mean:61) with already diagnosed malignant pleural effusions applying the ELISA method. The SPSS 15 program for Windows was used. Quantitative analysis showed high concentrations of IL-10 and IL-17 in pleural fluid and blood. Even though IL-17 levels -both blood and pleural- were lower than IL-10's, statistical correlation between blood and pleural concentations was proven, confirming once more the systematic action of these cytokines. At the same time high IL-17 levels in malignant effusions shows maybe a new perspective in understanding the pathophysiology of malignant pleural effusions. Our results confirm the pathogenetic role of these cytokines in malignant pleural effusions combining for the first time a pro- and an anti- inflammatory cytokine. The observation that IL-17 is elevated in malignant pleural effusions may give a new meaning in Virchow's remarks 100 years ago. Larger number of patients is needed to confirm our hypothesis.

    Delayed-onset pericardial effusion following cardiac surgery can give rise to significant morbidity due to its presentation as well as management by traditional surgical techniques. An institutional experience of a video-assisted thoracoscopic technique to create a pericardial window, with the advantages of a minimally invasive approach combined with excellent visualization in such patients, was reviewed. A retrospective analysis was conducted on all patients undergoing video-assisted thoracoscopic for delayed pericardial effusion after cardiac surgery from January 2001 to January 2006 at our center. Seven patients with echocardiographically diagnosed delayed tamponade underwent video-assisted thoracoscopy; 5 were receiving anticoagulants after valve replacement, and 2 had undergone heart transplantation. Pericardial windows were created under general anesthesia and single-lung ventilation using 2 to 3 trocars. Mean operative time was 45 min. There were no complications of the thoracoscopic technique. Video-assisted thoracoscopic creation of a pericardial window is safe and effective treatment for loculated pericardial effusions secondary to cardiac surgery.

    Management of symptomatic malignant pleural effusions is becoming more complex due to the range of treatment options, which include therapeutic thoracenteses, thoracoscopic talc pleurodesis, bedside pleurodesis with talc or other sclerosing agents via small-bore chest catheters, indwelling pleural catheters, surgery, or a combination of some of these procedures. Areas covered: Recent advances for the expanding range of treatment options in malignant pleural effusions are summarized, according to the best available evidence. Expert commentary: Selection of a treatment approach in malignant pleural effusions should take into account patient preferences and performance status, tumor type, predicted prognosis, presence of a non-expandable lung, and local experience or availability. The role of pleurodesis has decreased with the advent of indwelling pleural catheters, which provide a high degree of symptomatic relief on an outpatient basis and, therefore, are being positioned as a first choice therapy in many centers. Talc poudrage pleurodesis should probably be reserved for those situations in which pleural tumor invasion is discovered during diagnostic thoracoscopy. Ongoing randomized controlled trials will offer solid evidence on which of the available palliative approaches should be selected for each particular patient.

    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. PMID:28003826

    I report two patient presented to me with bilateral symmetrical ankle edema and bilateral acute iritis. A 42-year-old female of Indian origin and 30-year-old female from Somalia both presented with bilateral acute iritis. In the first patient, bilateral ankle edema preceded the onset of bilateral acute iritis. Bilateral ankle edema developed during the course of disease after onset of ocular symptoms in the second patient. Both patients did not suffer any significant ocular problem in the past, and on systemic examination, all clinical parameters were within normal limit. Lacrimal gland and conjunctival nodule biopsy established the final diagnosis of sarcoidosis in both cases, although the chest x-rays were normal.

    Abstract High serum lactate dehydrogenase (LDH) level, immunologic defects, enlarged mediastinal lymph nodes, and frequent hydration and diuresis in lymphoma patients may affect the development of pleural effusion (PE). The study was to assess the clinical utility of “Light criteria” and the “recommended algorithm for investigating PEs” in patients with lymphoma. The characteristics of 126 PEs of lymphoma patients who underwent diagnostic thoracentesis between January 1, 2003, and April 30, 2012, were reviewed. Using Light criteria, 29 (23%) PEs were incorrectly classified. The sensitivity for exudates in Light criteria was 88% and the specificity was only 44%. In 32 transudates, PE LDH correlated with blood LDH concentration (P < 0.001, r = 0.66). Nine transudates were misclassified as exudates (50%; 9/18) just due to PE LDH more than two-thirds the upper limits. Among the 56 bilateral PEs, 33 (59%) were exudates. Ten (63%) polymorphonuclear (PMN)-predominant exudative PEs were malignant. Infective PEs were often mononuclear (67%) rather than PMN predominant. When a patient has lymphoma with either unilateral or bilateral PE, thoracentesis for microbiological testing and cytology is imperative. Carefully clinical correlation in addition to the result from Light criteria and differential cell count is essential for prompt management. PMID:25929933

  10. Bimodal fitting or bilateral implantation?

    This paper summarises findings from studies that evaluated the benefits of bimodal fitting (combining a hearing aid and a cochlear implant in opposite ears) or bilateral cochlear implantation, relative to unilateral implantation, for children (Ching et al., 2007). On average, the size of binaural speech intelligibility advantages due to redundancy and head shadow was similar for the two bilateral conditions. An added advantage of bimodal fitting was that the low-frequency cues provided by acoustic hearing complemented the high-frequency cues conveyed by electric hearing in perception of voice and music. Some children with bilateral cochlear implants were able to use spatial separation between speech and noise to improve speech perception in noise. This is possibly a combined effect of the directional microphones in their implant systems and their ability to use spatial cues. The evidence to date supports the provision of hearing in two ears as the standard of care.

    Although Meigs' syndrome is regarded as a well-defined entity, contradictory data on pleural fluid characteristics have been presented, with some papers classifying it as a transudate, whereas others stating that it is an exudate.The aims of the study were: (1) to evaluate pleural fluid characteristics in patients with Meigs' syndrome and (2) to analyze the prevalence of transudative and exudative pleural effusion in relation to the applied definition of the syndrome.We performed a search through medical databases (MEDLINE, EMBASE, SCOPUS, and GOOGLE SCHOLAR) to identify papers on Meigs' syndrome published between 1940 and 2013. Two authors independently reviewed each paper searching for prespecified data: (1) signs and symptoms, (2) tumor characteristics, (3) clinical and laboratory data on ascites, (4) clinical, radiological, and laboratory data on pleural fluid, (5) clinical course after tumor removal. All case reports were reclassified according to a new unequivocal classification of Meigs' syndrome-related entities.A total of 653 papers were initially identified, and 454 articles reporting 541 patients were included in the final analysis. After reclassification according to our case definitions, there were 196, 113, and 108 patients defined as classic Meigs' syndrome, nonclassic Meigs' syndrome, and pseudo-Meigs' syndrome, respectively. Significantly more patients presented with right-sided than left-sided and bilateral pleural effusions (P < 0.001). Median volume of withdrawn pleural fluid was 2950 (1500-6000) mL. The classification of pleural effusion with the use of Light's criteria was possible in only 7 patients. In 6 of these patients pleural effusion met the criteria for an exudate. When the protein concentration > 3.0 g/dL was applied as a criterion of pleural exudate, 88.8% (80/90) of effusions were classified as exudates. Increasing the cut-off level to 3.5 g/dL resulted in only a modest decrease in the percentage of exudative effusions (81

    The identification of malignant cells in effusions by conventional cytology is hampered by its limited sensitivity and specificity. The aim of this study was to investigate the value of fluorescence in situ hybridization (FISH) as adjuncts to conventional cytologic examination in patients with malignant pleural effusions. We conducted a retrospective cohort study of 93 inpatients with pleural effusions (72 malignant pleural effusions metastatic from 11 different organs and 21 benign) over 23 months. All the patients came from Chinese northeast areas. Aspirated pleural fluid underwent cytologic examination and fluorescence in situ hybridization (FISH) for aneuploidy. We used FISH in single-colour or if appropriate in dual-colour evaluation to detect chromosomal aberrations (chromosomes 7, 11, and 17) in effusion cells as markers of malignancy, to raise the diagnostic yield and identified the efficiency by diagnostic biopsy. Predominant cytogenetic anomalies and patterns of intratumor cytogenetic heterogeneity were brought in relation to overall survival rate. Cytology alone confirmed malignant pleural effusions in 45 of 72 patients (sensitivity 63%), whereas FISH alone positively identified 48 of 72 patients (sensitivity 67%). Both tests had high specificity in predicting benign effusions. If cytology and FISH were considered together, they exhibited 88% sensitivity and 94.5% specificity in discriminating benign and malignant effusions. Combined, the two assays were more sensitive than either test alone. Although the positive predictive value of each test was 94.5%, the negative predictive value of cytology and FISH combined was 78%, better than 47% and 44% for FISH and cytology alone, respectively. There was a significantly prolonged survival rate for patients with aneuploidy for chromosome 17. FISH in combination with conventional cytology is a highly sensitive and specific diagnostic tool for detecting malignant cells in pleural effusions . The high sensitivity

    Nontypeable Haemophilus influenzae (NTHi) is associated with chronic otitis media (COM). In this study, we generated a murine model of COM by using eustachian tube (ET) obstruction and NTHi (107 CFU) inoculation into the tympanic bulla, and we investigated the relationship between regulatory T cells (Treg) and chronic inflammation in the middle ear. Middle ear effusions (MEEs) and middle ear mucosae (MEM) were collected at days 3 and 14 and at 1 and 2 months after inoculation. Untreated mice served as controls. MEEs were used for bacterial counts and to measure the concentrations of cytokines. MEM were collected for histological evaluation and flow cytometric analysis. Inflammation of the MEM was prolonged throughout this study, and the incidence of NTHi culture-positive MEE was 38% at 2 months after inoculation. The levels of interleukin-1β (IL-β), tumor necrosis factor alpha, IL-10, and transforming growth factor β were increased in the middle ear for up to 2 months after inoculation. CD4+ CD25+ FoxP3+ Treg accumulated in the middle ear, and the percentage of Treg in the MEM increased for up to 2 months after inoculation. Treg depletion induced a 99.9% reduction of bacterial counts in MEEs and also significantly reduced the ratio of NTHi culture-positive MEE. The levels of these cytokines were also reduced in MEEs. In summary, we developed a murine model of COM, and our findings indicate that Treg confer infectious tolerance to NTHi in the middle ear. PMID:26553466

    Complete cervical disruption is a rare and lethal injury secondary to high-energy trauma. Bilateral vertebral arterial breakdown is also a rare and lethal injury. This is the first reported clinical case of an 18-month-old girl who survived after combined cervical spinal cord disruption and bilateral vertebral arterial breakdown. Although she developed cardiopulmonary arrest at the accident site, resuscitation by a bystander, early fluid resuscitation, appropriate respiratory management, and subsequent surgical stabilization resulted in survival and preservation of higher cortical functions. She underwent surgery 1 week after hospitalization; her cervical spine was stabilized by posterior fixation using pedicle screws and transarticular screws. After the operation, the burst vertebra was gradually remodeled. Approximately 4 months later, she was transferred to a rehabilitation facility. Ten years later, she is attending to an elementary school, and she is able to speak and operate a wheelchair using a portable respiratory organ. We herein report an exceedingly rare case of cervical cord injury involving a combination of disruption of the cervical spine and bilateral vertebral arterial breakdown in a young child.

    Neurofibromatosis type 2 (NF-2) is characterized by multifocal proliferation of neural crest-derived cells. The characteristics finding of NF-2 is bilateral vestibular schwannomas. Combined hamartoma of retina and retinal epithelium (CHRRPE) is another associated finding. A 9 year-old-male child presented with left eye decreased vision for 3 months. Visual acuity was 0.0 and 0.8 LogMAR in the right and left eye, respectively. Left fundus showed an elevated, pigmented lesion with surface wrinkling and vascular tortuosity suggestive of CHRRPE with multiple presumed retinal astrocytic proliferations in mid-periphery. He had multiple café-au-lait spots. Optical coherence tomography confirmed clinical findings. Magnetic resonance imaging brain showed bilateral acoustic neuroma. Recognition of this rare finding as presenting feature of NF-2 can lead to earlier diagnosis which is vital to appropriate surveillance and possible surgical intervention. It is recommended that children with CHRRPE be screened for NF-2.

    Methanol poisoning is a rare but extremely hazardous form of intoxication, generally occurring after suicidal or accidental events. Methanol is a cheap and potent adulterant of illicit liquors. In India, we have witnessed number of mass emergencies due to adulterated alcohol consumption. Although Gujarat State had banned alcohol consumption since 1961, worse hooch tragedies have often taken place. The most severe consequences of methanol intoxication are blindness, a profound metabolic acidosis and various forms of neurological impairment; which occur characteristically after a latent period of several hours or days after ingestion. We present a unique case of acute methanol intoxication presented with, apart from metabolic acidosis and optic neuritis, involvement of central nervous system and peripheral nervous system. He had bilateral optic neuritis, delayed onset polyneuropathy with axonopathy, and radiculopathy. Magnetic resonance imaging findings were consistent with bilateral putaminal necrosis. PMID:23248510

    Pillared graphene structures, from a practical viewpoint, are very interesting novel carbon materials. Combining the properties of graphene and nanotubes, such as durability, chemical purity and a controlled structure, they were proven to be effective membranes for noble gas separation processes. Here, we examine their possible use for other, more commercially useful gas mixture separation, i.e. air and coal gas. The mechanism of air gas transport through the pillar channels is studied, and the prospective application of 2-D pillared membranes in effusion-like processes provided. The separative abilities of hybrid systems consisting of membranes with different channel diameters in relation to coal gas are proven to be promising.

    Grey matter and white matter changes within the brain are well defined in schizophrenia. However, most studies focused on either grey matter changes or white matter integrity separately; only in limited number of studies these changes were interpreted in the same frame. In addition, the relationship of these findings with clinical variables is not clearly established. Here, we aimed to investigate the grey matter and white matter changes in schizophrenia patients and exhibit the relation of these imaging findings with clinical variables. A total of 20 schizophrenia patients and 16 matched healthy controls underwent magnetic resonance imaging to investigate the grey matter and white matter alterations that occur in schizophrenia patients using voxel-based morphometry (VBM) and whole brain voxel-wise analysis of diffusion tensor imaging (DTI) parameters with SPM8, respectively. While the preprocessing steps of VBM were performed with the default parameters of VBM8 toolbox, the preprocessing steps of DTI were carried out using FSL. Additionally, VBM results were correlated with clinical variables. Bilateral insula showed decreased grey matter volume in schizophrenia patients compared with healthy controls (P < 0.01). The opposite contrast did not show a significant difference. Psychiatric scores, duration of illness, and age were not correlated with the decreased grey matter volume of insula in schizophrenia patients. DTI analysis revealed a significant increase in mean, radial, and axial diffusivity, mainly of the fibers of bilateral anterior thalamic radiation and superior longitudinal fasciculus with left predominance, which intersected with bilateral subinsular white matter (P < 0.05). Our findings suggest that insula may be the main affected brain region in schizophrenia, which is also well supported by the literature. Our results were independent of disease duration and schizophrenia symptoms. White matter alterations were observed within bilateral anterior

    To describe the placement technique, complications, and outcomes associated with use of the PleuralPort device for management of pleural effusion in dogs and cats. Case Series. Six dogs and 4 cats. Medical records of all animals with pleural effusion managed with the PleuralPort device were reviewed. Data regarding signalment, fluid analysis, placement technique, duration of function, duration of implantation, complications, and outcome were collected. Owners and referring veterinarians were contacted for follow-up information. Nine animals had chylous effusion and 1 dog had pleural carcinomatosis. Eleven ports were placed with 1 cat receiving bilateral ports. Four animals developed complications. One cat developed pneumothorax immediately after implantation and was euthanatized. In 2 dogs and 1 cat, the ports obstructed. The 6 remaining animals had functioning ports at time of death or resolution of effusion and no longer required use of the port. No significant port migration, irritation, or infection of the device was reported. Excluding the cat with pneumothorax, median duration of port function was 20 days (range 1-391), and median duration of port implantation was 391 days (range 6-723). The PleuralPort device is a feasible option for the management of pleural effusion in dogs and cats. © Copyright 2011 by The American College of Veterinary Surgeons.

  3. False-positive pericardial effusion due to breast attenuation on equilibrium radionuclide angiocardiography.

    2011-06-01

    Equilibrium radionuclide angiocardiography (ERNA) scans are used to evaluate left ventricular function and pericardial anatomy. A photopenic "U-halo" around the cardiac blood pool in the left anterior oblique (LAO) view is commonly seen with pericardial effusion. We describe findings of false-positive pericardial effusion due to breast attenuation in cancer patients. Several cases that demonstrated the photopenic U-halo in the LAO view did not have true pericardial effusion. The patients' breast size and how far the breast sagged in reference to the heart silhouette were visually observed in topograms. The oblique tilt position was evaluated to determine the effect it may have in creating the photopenic U-halo. A unique ERNA case demonstrating collateral vessels bilaterally in the breasts was used as a reference marker image to determine the effect of a slightly more anterior versus left lateral oblique tilt in the LAO view. Large breasts can overlie the heart in the LAO projection. The overlying breast can cause the appearance of pericardial effusion in the resulting image by attenuating tissues surrounding the heart. The positioning of the breast also affected the appearance of the photopenic halo. A patient with breast implants who had more upright breasts demonstrated a photopenic area anterior to the left ventricle, whereas a large breast that sagged more laterally demonstrated no photopenic area. Patients with large breasts may show a photopenic U-halo in the LAO view dependent on how far the breast sags in reference to the heart silhouette and on the positioning of the oblique tilt. The anterior image should be used to distinguish breast attenuation from a photopenic area surrounding the heart. If both the anterior view and the LAO view demonstrate the U-halo, acquiring another view with a slightly more anterior or lateral oblique position will demonstrate any inconsistency in the photopenic area, thereby excluding a diagnosis of pericardial effusion.

    The identification of parapneumonic effusions (PPE) requiring pleural drainage is challenging. We aimed to determine the diagnostic accuracy of radiological and pleural fluid findings in discriminating between PPE that need drainage (complicated PPE (CPPE)) and those that could be resolved with antibiotics only (uncomplicated PPE (UPPE)). A retrospective review of 641 consecutive PPE, of which 393 were categorized as CPPE and 248 as UPPE. Demographics, radiological (size and laterality on a chest radiograph) and pleural fluid parameters (pus, bacterial cultures, biochemistries) were compared among groups. Logistic regression was performed to determine variables useful for predicting chest drainage, and receiver-operating characteristic curves assisted in the selection of the best cutoff values. According to the likelihood ratios (LR), findings increasing the probability of chest tube usage the most were: effusions occupying ≥1/2 of the hemithorax (LR 13.5), pleural fluid pH ≤7.15 (LR 6.2), pleural fluid glucose ≤40mg/dL (LR 5.6), pus (LR 4.8), positive pleural fluid cultures (LR 3.6), and pleural fluid lactate dehydrogenase >2000U/L (LR 3.4). In the logistic regression analysis only the first two were selected as significant predictors of CPPE. In non-purulent effusions, the effusion's size and pleural fluid pH retained their discriminatory properties, in addition to a pleural fluid C-reactive protein (CRP) level >100mg/L. Large radiological effusions and a pleural fluid pH ≤7.15 were the best predictors for chest drainage in patients with PPE. In the subgroup of patients with non-purulent effusions, pleural fluid CRP also contributed to CPPE identification.

We report the case of a 5-year-old girl hospitalized for a unilateral eosinophilic pleural effusion due to Toxocara canis. Besides the fact that she was living in a squat, no other medical condition was reported. There was no other site of infection caused by the parasite and she was successfully treated with albendazole. This case report is obviously unique as very few cases of pleural effusion due to Toxocara canis are reported in literature, all in adult patients.

    To evaluate the value of diffusion-weighted imaging (DWI) in the differential diagnosis of pleural effusions. 58 pleural effusions (21 transudative, 37 exudative) were included in this prospective study. Single-shot echo-planar spin echo DWI was performed with two b factors (500 and 1000 s/mm (2)), and apparent diffusion coefficients (ADCs) were calculated. On diffusion- weighted (DW) trace images, signal intensity (SI) of the pleural effusions was visually compared to the SI of the paraspinal muscles with the use of a 3-point scale: 0: isointense, 1: moderately hyperintense, 2: significantly hyperintense. For quantitative evaluation, effusion- to-paraspinal muscle SI ratios, and ADCs of the effusions were compared between the groups. On visual evaluation, most of the transudative effusions were isointense, while most of the exudative effusions were hyperintense on DWI with b factors of 500 and 1000 s/mm (2). Quantitatively, with a b factor of 500 and 1000 s/mm(2), effusion-to-paraspinal muscle SI ratios of the exudative effusions were significantly higher than those of transudative effusions. The ADCs of the exudative effusions were significantly lower than those of transudative effusions (mean ADC was 3.3 x 10 (-3)+/- 0.7 mm(2)/s for exudative effusions, and 3.7 x 10 (-3)+/-0.3 mm(2)/s for transudative effusions). Setting the cutoff value at 3.6 x 10(-3), ADC had a sensitivity of 71% and a specificity of 63% for differentiating transudative from exudative effusions. DWI may help in the differential diagnosis of pleural effusions.

    One hundred sixty children with effusive otitis media who did not improve with medical treatment were reviewed. The evolution and complications observed in 294 ears treated by myringotomy and ventilation tubes (grommets) over a three-year period were analyzed. Otorrhea occurred during grommet placement in 11.6%. The disease remitted in 84%. Recurrences occurred in 15.3%: 4.8% had different degrees of tympanic atelectasia and 0.7% had perforation. Three per cent of the children were reoperated for bilateral recurrence of otitis. Younger children and those whose had delayed surgery had a worse outcome. Insertion of ear grommets improved hearing.

    A retrospective technical report. To assess the effect of bilateral C1 laminar hooks combined with C2 pedicle screw fixation for the treatment of C1-C2 instability. Various posterior atlantoaxial fixations for C1-C2 instability have been developed. However, due to anatomic anomalies of the vertebral artery, the smallness of the pedicle, trajectories of broken screws, or a lack of surgical experience, a simple atlantoaxial fixation technique with good safety and effectiveness is urgently needed. From January 2007 to September 2012, 18 patients with C1-C2 instability who underwent posterior bilateral C1 laminar hooks combined with C2 pedicle screw fixation were evaluated. Six patients had acute odontoid fractures (Anderson IIc type), 8 patients had odontoid pseudarthrosis, 3 had os odontoideum, and 1 had a traumatic rupture of the transverse ligament. The mean age at the time of surgery was 34.1 years. The clinical and radiographic analyses were performed before and after the operation and at follow-up. The follow-up period was 12-78 months (with an average follow-up period of 25.6 mo). All patients were relieved of pain and their neurological symptoms were substantially improved. The postoperative JOA score improved significantly (t=-7.234, P<0.001). No neurological or vascular complications occurred in these cases. The device was placed well and had not loosened or broken and plain radiographs revealed bony fusion in 17 patients. One patient had C1 posterior arch fracture 3 weeks postoperatively and she was followed up for 18 months without revision surgery. When appropriate patients were selected, bilateral C1 laminar hooks combined with C2 pedicle screw fixation can be an alternative method to treat C1-C2 instability effectively with a relatively simple procedure. Preoperative planning and evaluation were crucial for the solid atlantoaxial fusion.

    The software program generates 3D volume distribution of thermal effusivity within a test material from one-sided pulsed thermal imaging data. Thsi is the first software capable of accurate, fast and automated thermal tomographic imaging of inhomogeneous materials to produce 3D images similar to those obtained from 3D X-ray CT (all previous thermal-imaging software can only produce 2D results). Because thermal effusivity is an intrisic material property that is related to material constituent, density, conductivity, etc., quantitative imaging of effusivity allowed direct visualization of material's internal constituent/structure and damage distributions, thereby potentially leading to quantitative prediction of other material properties such as strength. I can be therefre be used for 3D imaging of material structure in fundamental material studies, nondestructive characterization of defects/flaws in structural engineering components, health monitoring of material damage and degradation during service, and medical imaging and diagnostics. This technology is one-sided, non contact and sensitive to material's thermal property and discontinuity. One major advantage of this tomographic technology over x-ray CT and ultrasounds is its natural efficiency for 3D imaging of the volume under a large surface area. This software is implemented with a method for thermal computed tomography of thermal effusivity from one-sided pulsed thermal imaging (or thermography) data. The method is based on several solutions of the governing heat transfer equation under pulsed thermography test condition. In particular, it consists of three components. 1) It utilized the thermal effusivity as the imaging parameter to construct the 3D image. 2) It established a relationship between the space (depth) and the time, because thermography data are in the time domain. 3) It incorporated a deconvolution algorithm to solve the depth porfile of the material thermal effusivity from the measured

    Clinicians often encounter left pleural effusion after esophagectomy, which sometimes necessitates thoracentesis. We have introduced a new drainage method, bilateral pleural drainage by single Blake drain (BDSD), which we have been using since April 2013. This study aims to evaluate the performance of the BDSD. The BDSD method employs a 15-F Blake drain inserted from the right thoracic cavity to the left thoracic cavity across the posterior mediastinum. The conventional drain (CD) group consisted of 50 patients with a 19-F Blake drain placed in the right thoracic cavity during the period from April 2012 to March 2013. The BDSD group consisted of 54 patients treated from April 2013 to June 2014. The amount of total drainage in the BDSD group was significantly higher than that in the CD group (P < 0.0001). The rates of left pleural effusion and left lower lobe atelectasis in the BDSD group were significantly lower than those in the CD group (P < 0.0001 and P < 0.0001, respectively). No patients developed a left pleural effusion necessitating thoracentesis drainage in the BDSD group. Compared with the conventional method, BDSD was able to evacuate bilateral pleural effusion more effectively, and the incidences of left pleural effusion and left atelectasis were lower. This method is therefore clinically useful after esophagectomy.

    Magnetic resonance imaging (MRI) scores for haemophilic arthropathy are useful for evaluation of early and moderate arthropathy. The most recent additive International Prophylaxis Study Group (IPSG) MRI scale for haemophilic arthropathy includes joint effusion. However, it is unknown whether joint effusion is haemophilia specific. Correct interpretation of joint effusion is needed for outcome assessment of prophylactic therapies in haemophilia care. The aim of this study was to compare joint effusion on MRI between young adults with haemophilia and healthy controls. MRI's of both knees and ankles of 26 haemophilic patients (104 joints) and 30 healthy active men (120 joints) were assessed. Scans in both groups were performed in 2009/2010 and 2012 respectively. Joint effusion was measured and scored according to the MRI atlas referred by the IPSG MRI scale for haemophilic arthropathy. Median age of haemophilic patients and healthy controls was 21 and 24 years respectively. In haemophilic patients 23% of knees and 22% of ankles showed joint effusion. Healthy controls had significantly more positive scores for knee effusion (67%, P < 0.01) and a comparable scores for effusion in the ankle (17%). Joint effusion according to criteria of the IPSG MRI scale was observed significantly more often in knees of healthy controls, while findings in ankles were similar. These data suggest that joint effusion in knees and ankles is not haemophilia specific. Inclusion of joint effusion in the MRI scale is expected to reduce its specificity for haemophilic arthropathy.

    Yellow nail syndrome (YNS) can be associated with a pleural effusion (PE) but the characteristics of these patients are not well defined. We performed a systematic review across four electronic databases for studies reporting clinical findings, PE characteristics, and most effective treatment of YNS. Case descriptions and retrospective studies were included, unrestricted by year of publication. We reviewed 112 studies (150 patients), spanning a period of nearly 50 years. The male/female ratio was 1.2/1. The median age was 60 years (range: 0-88). Seventy-eight percent were between 41-80 years old. All cases had lymphoedema and 85.6% had yellow nails. PEs were bilateral in 68.3%. The appearance of the fluid was serous in 75.3%, milky in 22.3% and purulent in 3.5%. The PE was an exudate in 94.7% with lymphocytic predominance in 96% with a low count of nucleated cells. In 61 of 66 (92.4%) of patients, pleural fluid protein values were >3 g/dL, and typically higher than pleural fluid LDH. Pleurodesis and decortication/pleurectomy were effective in 81.8% and 88.9% of cases, respectively, in the treatment of symptomatic PEs. The development of YNS and PE occurs between the fifth to eighth decade of life and is associated with lymphoedema. The PE is usually bilateral and behaves as a lymphocyte-predominant exudate. The most effective treatments appear to be pleurodesis and decortication/pleurectomy.

It is associated to chylothorax in approximately 3% of cases. We report the case of a 52 years old woman with diagnosis of advanced breast cancer. She was admitted with bilateral pleural effusion and echocardiographic signs of cardiac tamponade. A CT scan disclosed multiple mediastinal lymphadenopathy. The level of tryglicerides in pleural effusion was 372 mg/dl. A percutaneous pericardiocentesis was performed, obtaining chyle, with 984 mg/dl of tryglicerides and cholesterol 90 mg/dl levels. Treatment strategy was modified. We reviewed pathophysiology, diagnostic criteria and treatment of this rare entity.

    We report a case of a 24-year-old female with a history of asthma and gastroesophageal reflux disease (GERD). She presented to the emergency room with severe chest pain, chest tightness, and shortness of breath following an upper respiratory tract infection. The patient reported that she had a cough and runny nose one week prior to this presentation, followed by a sudden sharp pain in the center of the chest 8/10 in intensity on the visual analog scale and pleuritic in nature, which aggravated by deep breathing and lying down flat. It was relieved by sitting up straight and did not radiate to her left arm or jaw. Computed tomography (CT) scan of the chest, posteroanterior and lateral views, showed a mild left pleural effusion with adjacent left basilar atelectasis/infiltrate. CT angiography of the chest with axial contrast showed mild left pleural effusion as well as a small pericardial effusion with bilateral lower lobe interstitial infiltrates. There was no evidence of pulmonary embolism. Electrocardiogram (EKG) showed no apparent ST segment elevation or depression that would be consistent with pericarditis, or acute ischemia or infarct. There was non-specific T wave abnormality. The patient was prescribed prednisone on a tapering dose. On follow-up visit, her condition significantly improved. PMID:28083450

    Lava flows are a recurring and widespread form of volcanic activity that threaten people and property around the world. The growing demographic congestion around volcanic structures increases the potential risks and costs that lava flows represent, and leads to a pressing need for faster and more accurate assessment of lava flow impact. To fully evaluate potential effects and losses that an effusive eruption may cause to society, property and environment, it is necessary to consider the hazard, the distribution of the exposed elements at stake and the associated vulnerability. Lava flow hazard assessment is at an advanced state, whereas comprehensive vulnerability assessment is lacking. Cataloguing and analyzing volcanic impacts provide insight on likely societal and physical vulnerabilities during future eruptions. Here we quantify the lava flow impact of two past main effusive eruptions of Etna volcano: the 1669, which is the biggest and destructive flank eruption to have occurred on Etna in historical time, and the 1981, lasting only 6 days, but characterized by an intense eruptive dynamics. Different elements at stake are considered, including population, hospitals, critical facilities, buildings of historic value, industrial infrastructures, gas and electricity networks, railways, roads, footways and finally land use. All these elements were combined with the 1669 and 1981 lava flow fields to quantify the social damage and economic loss.

    Background: Semi-rigid thoracoscopy is a safe and efficacious procedure in patients with undiagnosed pleural effusion. Literature on its utility from developing countries is limited. We herein describe our initial experience on the utility of semi-rigid thoracoscopy from a tertiary care teaching and referral center in north India. We also perform a systematic review of studies reporting the utility of semi-rigid thoracoscopy from India. Patients and Methods: The primary objective was to evaluate the diagnostic utility of semi-rigid thoracoscopy in patients with undiagnosed exudative pleural effusion. Semi-rigid thoracoscopy was performed under local anesthesia and conscious sedation in the bronchoscopy suite. Results: A total of 48 patients underwent semi-rigid thoracoscopy between August 2012 and December 2013 for undiagnosed pleural effusion. Mean age was 50.9 ± 14.1 years (range: 17–78 years). Pre-procedure clinico-radiological diagnoses were malignant pleural effusion [36 patients (75%)], tuberculosis (TB) [10 (20.83%) patients], and empyema [2 patients (4.17%)]. Patients with empyema underwent the procedure for pleural biopsy, optimal placement of intercostal tube and adhesiolysis. Thoracoscopic pleural biopsy diagnosed pleural malignancy in 30 (62.5%) patients and TB in 2 (4.17%) patients. Fourteen (29.17%) patients were diagnosed with non-specific pleuritis and normal pleura was diagnosed on a pleural biopsy in 2 (4.17%) patients. Overall, a definitive diagnosis of either pleural malignancy or TB was obtained in 32 (66.7%) patients. Combined overall sensitivity, specificity, positive predictive value and negative predictive value of thoracoscopic pleural biopsy for malignant pleural effusion were 96.77%, 100%, 100% and 66.67%, respectively. There was no procedure-related mortality. On performing a systematic review of literature, four studies on semi-rigid thoracoscopy from India were identified. Conclusion: Semi-rigid thoracoscopy is a safe and

    Proper management of abdominal compartment syndrome and open abdomen is important for improving the survival of critically ill patients. However, in cases requiring a prolonged period of open abdomen, it is frequently difficult to perform definitive fascial closure due to lateralization of the abdominal musculature. We herein present a novel combined technique for managing open abdomen. A 74-year-old male with diffuse peritonitis was transferred to our department, after which a long period of open abdomen made it difficult to achieve fascial closure. Polypropylene mesh was sutured to the fascial edges to reduce the gap, which was then serially tightened under negative pressure wound therapy. However, since it was not possible to accomplish definitive fascial closure, abdominal closure was performed using the bilateral anterior rectus abdominis sheath turnover flap method after removing the mesh, without any complications. This combined technique may be an effective alternative in patients requiring open abdomen with subsequent difficulty in achieving definitive fascial closure.

    Combination therapy is an effective approach to simultaneously target multiple pathogenic factors of acne. International consensus guidelines recommend the use of topical retinoids and benzoyl peroxide (BPO) for acne treatment. These drugs are often prescribed as a free combination without any safety concern associated with antibiotic use. A 3-week, randomized, controlled, investigator-blinded, single-center, bilateral (split-face), dose-assessment study was conducted comparing the cutaneous tolerability of 2 adapalene-BPO fixed-dose combination products versus various concentrations of BPO monotherapy applied once daily. Sixty healthy participants were randomized to one of the following treatment groups: adapalene 0.1%-BPO 2.5% combination product versus BPO 2.5% monotherapy; adapalene 0.1%-BPO 2.5% combination product versus BPO 5% monotherapy; adapalene 0.1%-BPO 5% combination product versus BPO 5% monotherapy; and adapalene 0.1%-BPO 5% combination product versus BPO 10% monotherapy. Assessments included total sum score (TSS) of irritation signs/ symptoms (erythema, scaling/desquamation, dryness, pruritus, stinging/burning) averaged over all postbaseline visits, individual irritation signs/symptoms (worst score), and adverse events. The overall cutaneous tolerability profile of the adapalene 0.1%-BPO 2.5% combination product was better than the combination with BPO 5% and similar to BPO 2.5% or 5% monotherapy. The combination product with BPO 5% induced significantly more irritation than BPO 5% monotherapy (P < .001) or BPO 10% monotherapy (P = .001). In conclusion, the new fixed-dose adapalene 0.1%-BPO 2.5% combination product provided the best overall cutaneous tolerability profile relative to BPO monotherapy.

    The frequency of "complicated" pleural effusions (CPE) (i.e., pleural fluid pH ≤ 7.2 and/or glucose ≤60 mg/dL) of tuberculous origin (CTPE) is not well reported. This study aims to quantify their prevalence, and develop a score to differentiate CTPE from complicated parapneumonic effusions (CPPE). Retrospective analysis of databases from three Spanish hospitals which included patients with CTPE and CPPE. Forty percent of the study population served to generate a scoring system (COMPLES, COMplicated PLeural Effusion Score) that was further validated in the remaining 60 %. During the study period (1992-2015) 549 patients were diagnosed with tuberculous effusions and 434 parapneumonic effusions, of whom 25 and 64 %, respectively, had CPE. COMPLES was based on the combination of pleural fluid adenosine deaminase (ADA), the percentage of mononuclear cells (MNC %), pH, and age. The cutoff values and assigned scores were: ADA (<46 IU/L [0 points], 46-100 IU/L [4 points], ≥100 IU/L [6 points]), MNC % (<10 % [0 points], 10-50 [3 points], >50 [8 points]), pH (<7.07 [0 points], 7.07-7.20 [3 points], >7.20 [5 points]), and age (≥30 [0 points], <30 years [3 points]). A sum of 12 or more points had 97 % sensitivity, 92 % specificity, likelihood ratio positive 12.3, likelihood ratio negative 0.03, and area under the curve of 0.947 for identifying CTPE versus CPPE in the validation set. CPE is not an unusual presentation of tuberculosis. A simple new scoring system provides a reliable tool for differentiating between CTPE and CPPE.

    Striking an adequate balance between bleeding risks and prevention of stent thrombosis can be challenging in the setting of percutaneous coronary intervention (PCI) with drug eluting stents (DES) in acute myocardial infarction (MI). This is more pronounced in patients treated with both low molecular weight heparin (LMWH) and dual antiplatelet therapy (DAPT). Prasugrel, a second generation thienopyridine with more potent platelet inhibition capability, is associated with significant bleeding risks. This risk of bleeding is often underestimated when prescribing pharmacological agents such as DAPT and LMWH, designed to reduce ischaemic events following PCI in acute MI. Life-threatening haemorrhagic pericardial and pleural effusions not associated with access site bleeding are a rare example of such bleeding complications. We report a case of a Bangladeshi male who developed cardiac tamponade resulting from haemorrhagic pericardial effusion as well as bilateral pleural effusions, 9 days after PCI with a DES, while on prasugrel and aspirin. He had presented late with inferior ST elevation myocardial infarction (STEMI), and was therefore also given enoxaparin initially. Haemorrhagic pericardial and pleural fluid were drained, and the patient was discharged on DAPT comprising of aspirin and clopidogrel. Following PCI to obtuse marginal, which was done as a staged procedure 6 months later, he was commenced on ticagrelor instead of clopidogrel. He developed no further bleeding complications over 1 year of follow up. Non-access site bleeding such as this, leading to haemorrhagic pericardial and pleural effusions can be rare and life-threatening. Furthermore, patients with acute coronary syndromes (ACS) have marked variation in their risk of major bleeding. Since haemorrhagic complications are associated with mortality, maintaining a balance between the risk of recurrent ischemia and that of bleeding is of paramount importance.

    Thoracoscopy has been around for decades, advocated by some, but until recently, ignored by many. Not surprisingly, its diagnostic and therapeutic efficacy in patients with suspected or proven malignant pleural effusions has withstood the test of time. Today, the potential benefits of thoracoscopy must be weighed against its cost in patients with limited life expectancy. Although diagnostic thoracoscopy requires only overnight hospitalization, pleurodesis imposes a longer hospital stay. The discomfort of an indwelling chest tube, the need for hospitalization, and the financial burden of thoracoscopic procedures compared with less-invasive means of pleural investigation and pleurodesis must be taken into account on an individual basis. Thoracoscopy should not be performed for the sake of intervention. Its indications and all diagnostic or therapeutic alternatives should always be carefully examined. Its role, however, in the diagnosis and treatment of patients with malignant pleural effusions is undeniable. The diagnostic accuracy of thoracoscopic pleural biopsy is excellent. Several studies demonstrate that thoracoscopic talc pleurodesis is more frequently successful than other methods of pleurodesis. As a staging procedure, thoracoscopy helps determine extent of disease, and possibly, prognosis in patients with metastatic pleural carcinomatosis, lung cancer, and malignant mesothelioma. As this procedure is increasingly rediscovered by our medical and surgical communities, greater clinical and experimental investigation aimed at establishing successful management strategies in patients with malignant pleural effusions will hopefully occur.

    Chylous joint effusion is a rare condition in which synovial fluids containing large amounts of lipids take on a milky appearance as a result. We report on a 19-year-old male patient with posttraumatic chylous knee effusion. Several days after striking his knee against the ground because of a traffic accident, his left knee showed obvious swelling. Aspiration of his knee was performed, yielding 70ml of purulent-appearing fluid. To distinguish this condition from purulent or tuberculosis arthritis, arthroscopic biopsy and debridement were performed. Arthroscopic examination visualized distinctive yellow-white soft lesions covering much of the joint capsule, resembling a cobweb. Tissue cultures for bacteria were negative. Pathologically, we identified clusters of xanthoma cells with fibrin exudation due to disruption of the synovium and intra-articular fat pad necrosis. Centrifuging the aspiration fluid yielded a thick creamy lipid layer as the supernatant. A fresh drop preparation showed that the specimen contained innumerable fat globules, which stained red with oil red O stain. The patient was able to walk without difficulty or further swelling of his knee at the end of the second postoperative week. Posttraumatic chylous effusion is self-limited. Purulent arthritis or tuberculosis arthritis, however, should still be the presumptive diagnosis in such cases. Arthroscopic irrigation and debridement should be considered for these traumatic cases to confirm diagnosis and to speed up recovery.

  11. The Differential Diagnosis of Pleural Effusions

    1982-01-01

    The presence of pleural effusion enables a physician to obtain a specimen of a body cavity fluid easily. With a systematic analysis of the pleural fluid, in conjunction with the clinical features and ancillary laboratory data, a clinician should be able to arrive at either a presumptive or definitive diagnosis in approximately 90 percent of cases. Selectivity should be exercised in ordering analyses on pleural fluid. The first important deductive step is to decide whether the effusion is a transudate (due to imbalances in hydrostatic or oncotic pressures) or an exudate (inflammatory); serum protein and lactate dehydrogenase measurements will be decisive. The differential diagnosis of a transudate is relatively limited and usually easily discernible from the clinical presentation. The differential diagnosis of exudate poses a more difficult challenge for clinicians. The use of certain pleural fluid tests such as leukocyte count and differential, glucose, pH and, when indicated, pleural fluid amylase determinations, helps to narrow the differential diagnosis of an exudative pleural effusion.

The criteria of enrolled patients were as follows: (1) history of asbestos exposure; (2) presence of pleural effusion determined by chest X-ray, CT, and thoracentesis; and (3) the absence of other causes of effusion. Clinical information was retrospectively analysed and the radiological images were reviewed. There were 110 BAPE patients between 1991 and 2012. All were males and the median age at diagnosis was 74 years. The median duration of asbestos exposure and period of latency for disease onset of BAPE were 31 and 48 years, respectively. Mean values of hyaluronic acid, adenosine deaminase, and carcinoembryonic antigen in the pleural fluid were 39,840 ng/mL, 23.9 IU/L, and 1.8 ng/mL, respectively. Pleural plaques were detected in 98 cases (89.1%). Asbestosis was present in 6 (5.5%) cases, rounded atelectasis was detected in 41 (37.3%) cases, and diffuse pleural thickening (DPT) was detected in 30 (27.3%) cases. One case developed lung cancer (LC) before and after BAPE. None of the cases developed malignant pleural mesothelioma (MPM) during the follow-up. PMID:26689234

    Historically, pleural effusions have been attributed to a single cause. There is growing recognition that a substantial proportion of pleural effusions may have more than one underlying cause. The purpose of this review is to summarise recent findings regarding the diagnosis and treatment of effusions secondary to more than one aetiology. A recent prospective study identified that 30% of pleural effusions had more than one underlying aetiology. With a rising prevalence of cardiovascular and malignant disease, the incidence of the complex pleural patient is increasing. The use of biomarkers, including pro-B-type natriuretic peptide, have been suggested as a way of identifying contributing disease process. Understanding that there are potentially concurrent causes to a pleural effusion is vital in establishing the diagnoses of multiple underlying aetiologies. New diagnostic pathways, with increasing use of biomarkers, will be required to identify the complex pleural effusion. Further studies on whether the targeting of separate aetiologies improves outcomes will help develop future management strategies.

    Pleural effusions are considered rare in cystic fibrosis (CF) patients. There is a paucity of available information in the literature concerning the nature and significance of pleural effusions in non-transplanted CF patients. We conducted a multicenter retrospective evaluation of non-transplanted adult CF patients. Given the small sample size, only descriptive statistics were performed. A total of 17 CF patients with pleural effusion were identified, of whom 9 patients underwent thoracentesis. The crude incidence of pleural effusion was 43 per 10,000 person-years in hospitalized CF patients at large CF centers. All sampled effusions were inflammatory in nature. All samples submitted for culture grew at least one organism. Pleural effusions are rare in adult non-transplanted CF patients. These fluid collections appear to be quite inflammatory with a higher rate of empyema than in the general population. Copyright © 2016 European Cystic Fibrosis Society. Published by Elsevier B.V.

    Hyaluronic acid (HA) is a component of extracellular matrix and may play a role in the pleural inflammation which is implicated in parapneumonic effusions.The aim of the current study was to investigate HA levels in serum and pleura in patients with parapneumonic effusions. We prospectively studied pleural and serum levels of HA in 58 patients with pleural effusions due to infection (complicated and uncomplicated parapneumonic effusions), malignant effusions and transudative effusions due to congestive heart failure. In addition to HA, TNF-alpha and IL-beta levels were determined in pleural fluid and serum by ELISA. The median +/- SD HA levels (pg/ml) in pleural fluid of patients with complicated effusions (39.058 +/- 11.208) were significantly increased (p < 0.005), compared to those with uncomplicated parapneumonic effusions (11.230 +/- 1.969), malignant effusions (10.837 +/- 4.803) or congestive heart failure (5.392 +/- 3.133). There was no correlation between pleural fluid and serum HA values. Pleural fluid TNF-alpha levels (146 +/- 127 pg/mL) and IL-1beta levels (133.4 +/- 156 pg/mL) were significantly higher in patients with complicated parapneumonic effusions compared to patients with other types of effusion (p < 0.05). No significant association between HA and TNF-alpha or IL-1beta was found. CONCLUSIONS. HA may play a significant role in the inflammatory process which characterises exudative infectious pleuritis. Further investigation might reveal whether HA is a useful marker in the management of parapneumonic effusions.

    Pleural effusions occur when fluid accumulates between the visceral and parietal pleura in the chest cavity, preventing the lung from expanding fully during inspiration. The reduction in lung volume, depression of the diaphragm and reduced chest wall compliance cause dyspnoea, and occasionally pain or cough. Pleural effusion is a complex problem caused by a variety of conditions requiring different treatment depending on the underlying diagnosis. This article discusses the causes and treatment of pleural effusions, referencing guidelines produced by the British Thoracic Society.

    Pleural effusions are common in critically ill patients. Most effusions in intensive care unit (ICU) patients are of limited clinical significance; however, some are important and require aggressive management. Transudative effusions in the ICU are commonly caused by volume overload, decreased plasma oncotic pressure, and regions of altered pleural pressure attributable to atelectasis and mechanical ventilation. Exudates are sequelae of pulmonary or pleural infection, pulmonary embolism, postsurgical complications, and malignancy. Increases in pleural fluid volume are accommodated principally by chest wall expansion and, to a lesser degree, by lung collapse. Studies in mechanically ventilated patients suggest that pleural fluid drainage can result in improved oxygenation for up to 48 hours, but data on clinical outcomes are limited. Mechanically ventilated patients with pleural effusions should be semirecumbant and treated with higher levels of positive-end expiratory pressure. Rarely, large effusions can cause cardiac tamponade or tension physiology, requiring urgent drainage. Bedside ultrasound is both sensitive and specific for diagnosing pleural effusions in mechanically ventilated patients. Sonographic findings of septation and homogenous echogenicity may suggest an exudative effusion, but definitive diagnosis requires pleural fluid sampling. Thoracentesis should be carried out under ultrasound guidance. Antibiotic regimens for parapneumonic effusions should be based on current pneumonia guidelines, and anaerobic coverage should be included in the case of empyema. Decompression of the pleural space may be necessary to improve respiratory mechanics, as well as to treat complicated effusions. While small-bore catheters inserted under ultrasound guidance may be used for nonseptated effusions, surgical consultation should be sought in cases where this approach fails, or where the effusion appears complex and septated at the outset. Further research is needed to

    With the increase in incidence of ectopic pregnancy over the decades, bilateral ectopic pregnancy is also increasing. It is usually associated with assisted reproductive techniques (ART) but in recent years few cases of spontaneous bilateral ectopic pregnancy have been reported. Gynaecologists should be aware of this and that ultrasonography has limitations in diagnosis. In cases of ectopic pregnancy where contralateral adnexa is not clearly identified on ultrasound and fertility needs to be conserved, patient should be managed by experts in well equipped centres. A case of spontaneous bilateral tubal pregnancy that remained undiagnosed till laparotomy, is described.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    Unstated and unacknowledged bias has a profound impact on the nature and implementation of integrative education models. Integrative education is the process of training conventional biomedical and traditional Chinese medicine practitioners in each tradition such that patient care may be effectively coordinated. A bilateral education model ensures that students in each tradition are cross-taught by experts from the ‘other’ tradition, imparting knowledge and values in unison. Acculturation is foundational to bilateral integrative medical education and practice. Principles are discussed for an open-minded bilateral educational model that can result in a new generation of integrative medicine teachers. PMID:16786060

    This case report describes the disease progression of a male cat with pericardial effusion. Clinical signs (dyspnea, lethargy, and weakness) started very acutely. The initial laboratory profile showed only an increase in alanine aminotransferase enzyme activity. Diagnostic imaging revealed pericardial effusion. Effusion analysis showed a Rivalta-positive, modified transudate. Detection of feline coronavirus antigen in macrophages was negative. General condition and laboratory parameters dramatically worsened within seven days. Therefore, the owners decided to euthanize the cat. Even if effusion variables are macroscopically and microscopically suspicious for FIP, a definitive diagnosis of FIP could only be made by histology (including immunhistochemical staining).

    A pleural effusion is excess fluid that collects in the pleural cavity, the fluid-filled space that surrounds the lungs. Surplus amounts of such fluid can impair breathing by limiting the expansion of the lungs during inhalation. Measuring the fluid volume is indicative of the effectiveness of any treatment but, due to the similarity to surround regions, fragments of collapsed lung present and topological changes; accurate quantification of the effusion volume is a difficult imaging problem. A novel code is presented which performs conditional region growth to accurately segment the effusion shape across a dataset. We demonstrate the applicability of our technique in the segmentation of pleural effusion and pulmonary masses.

    A prospective study (1984-87) on the immunocytochemical identification of cancer cells in effusions using HMFG2 monoclonal antibody, and in addition, monoclonal anti-CEA and B72.3 antibodies in cases of suspected mesothelioma, was undertaken. On the basis of cytology alone, of a total of 2362 pleural, peritoneal, and pericardial effusions, 525 cases were diagnosed as positive and 1485 as negative for neoplastic cells, while in 352 (15%) specimens from 307 patients the diagnosis was doubtful. Sections of the embedded sediment of doubtful cases were tested with HMFG2 antibody and proved positive in 215 cases, negative in 108, and inconclusive in 29. The results were checked by following the clinical outcome of the cases. The method was specific in identifying cancer cells in cases at best diagnosed as suspicious on the basis of cytology alone; this represents a clear diagnostic gain. Sensitivity of the test, however, was relatively low (41%). Combined cytological and immunocytochemical characteristics (CEA negative and only some of the neoplastic cells positive with HMFG2 and B72.3 monoclonal antibodies) permitted diagnosis on the effusions of most cases of mesothelioma. The impact of the diagnosis on the progress of the disease was not appreciable as no difference in outcome was noted, irrespective of whether cancer cells had been recognised. The occurrence of an effusion remains an ominous sign in most patients treated for cancer. Images PMID:2685053

    The bilateral lateral periodontal cyst is a rare nasological entity, which despite clinical and radiological presentation is being diagnosed by histological characteristics. It is asymptomatic in nature and is observed in routine radiography. The aim and objective of this article is to present a rare case of bilateral lateral periodontal cyst in a 14-year-old child. The clinical and radiographical findings, along with its management have been discussed. Enucleation of bilateral cyst without extraction of the adjacent tooth was performed. Lesion samples were sent for histopathological analysis. The histopathological analysis revealed a thin, non keratinised stratified squamous epithelium resembling reduced enamel epithelium. Epithelial plaques were also seen. A clinicopathological correlation incorporating the surgical, radiographical and gold standard histopathological findings was obtained to suggest the final diagnosis of the bilateral lateral periodontal cyst.

    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.

    The diagnosis of tuberculous aetiology in pericardial effusions is important since the prognosis is excellent with specific treatment. The clinical features may not be distinctive and the diagnosis could be missed particularly with tamponade. With the spread of HIV infection the incidence has increased. The diagnosis largely depends on histopathology of the pericardial tissue or culture of Mycobacterium tuberculosis from this tissue or fluid, but patients without haemodynamic compromise do not require pericardiocentesis. Histopathology may, however, show non-specific findings in a significant number. This review is an update on the diagnostic difficulties, current research, and criteria for diagnosis. PMID:15138314

    Distinguishing malignant mesothelioma (MM) from reactive mesothelial hyperplasia (RM) may be difficult in effusions. This study tested the hypothesis that immunocytochemistry (IC) in effusion cell blocks (CB) can distinguish MM from RM and that the results may be applied to individual specimens. External validation of a risk score (RS) model associating sensitivity and specificity was applied to an external set of MM and RM specimens from a separate institution. Forty three effusion cytology CBs of 25 confirmed malignant mesotheliomas were compared to CBs of 23 benign mesothelial effusions without inflammation and 13 reactive mesothelial proliferations associated with inflammation. Glut-1, EMA, and Desmin expression were evaluated by immunocytochemistry on CBs. Each antibody was compared using ROC values, where the area under the curve (AUC) was 0.90, 0.82, and 0.84 for Glut-1, EMA, and Desmin, respectively. Logistic regression (LR) analysis was applied to a combination of Glut-1 and EMA. A combined ROC curve was modeled for Glut-1 and EMA (AUC = 0.93). A RS = 2 × (Glut-1%) + 1 × (EMA%) was created from this ROC curve. When applied to an external set of MM and RM, the RS resulted in an ROC with AUC = 0.91. In conclusion, a RS derived from a LR of Glut-1 and EMA IC greatly improves the distinction between MM from RM cells in individual effusions. The study illustrates principles of evidence-based pathology concerning internal and external test performance in the differential diagnosis of MM versus RM.

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    Purpose: We investigated clinical and treatment-related factors as predictors of symptomatic pericardial effusion in esophageal cancer patients after concurrent chemoradiation therapy. Methods and Materials: We reviewed 214 consecutive primary esophageal cancer patients treated with concurrent chemoradiation therapy between 2001 and 2010 in our institute. Pericardial effusion was detected on follow-up computed tomography. Symptomatic effusion was defined as effusion ≥grade 3 according to Common Terminology Criteria for Adverse Events v4.0 criteria. Percent volume irradiated with 5 to 65 Gy (V5-V65) and mean dose to the pericardium were evaluated employing dose-volume histograms. To evaluate dosimetry for patients treated with two-dimensional planning in the earlier period (2001-2005), computed tomography data at diagnosis were transferred to a treatment planning system to reconstruct three-dimensional plans without modification. Optimal dosimetric thresholds for symptomatic pericardial effusion were calculated by receiver operating characteristic curves. Associating clinical and treatment-related risk factors for symptomatic pericardial effusion were detected by univariate and multivariate analyses. Results: The median follow-up was 29 (range, 6-121) months for eligible 167 patients. Symptomatic pericardial effusion was observed in 14 (8.4%) patients. Dosimetric analyses revealed average values of V30 to V45 for the pericardium and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those with asymptomatic pericardial effusion (P<.05). Pericardial V5 to V55 and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those without pericardial effusion (P<.001). Mean pericardial doses of 36.5 Gy and V45 of 58% were selected as optimal cutoff values for predicting symptomatic pericardial effusion. Multivariate analysis identified mean pericardial dose as the

    The use of topical medications for acne vulgaris is often limited by their irritant properties. Newer combination preparations are available and offer convenience, but irritant potential may still be a hindrance, perhaps more so with the combination of 2 agents. Few studies have compared these formulations directly for tolerability. We sought to compare the tolerability of 2 combination topical acne products, clindamycin 1.2%-tretinoin 0.025% (CLIN/RA) gel and benzoyl peroxide 2.5%-adapalene 0.1% (BPO/ADA) gel. CLIN/RA and BPO/ADA were applied daily to opposite sides of a subject's face for 21 days in a double-blinded fashion. Investigators' Global Assessments and study subject self-assessments of burning/stinging, itching, erythema, and dryness/scaling were collected. Transepidermal water loss (TEWL) was also measured as an objective measure of skin irritation. A mixed model analysis and repeated-measures analysis of variance were used to compare outcomes for both acne formulations. CLIN/RA produced significantly less burning/stinging than BPO/ADA (P<.001) as well as significantly less pruritus than BPO/ ADA (P<.001). BPO/ADA caused significantly more TEWL than CLIN/RA (P=.005). There was no significant difference in the amount of erythema or the amount of dryness/scaling caused by either formulation. CLIN/RA produced significantly less skin irritancy and TEWL than BPO/ADA.

    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.

    The Authors present the first case described among us of benign pleural effusion of an asbestotic origin. They stress the importance of thoracoscopy (pleuroscopy) in the diagnosis of this situation. Attention is drawn to the fact that asbestotic lesions and asbestotic bodies have been found in the lung and, in particular, in the parietal pleura as well. They emphasize the fact that exposure to asbestos was not realized by the patient, which made the clarification of the situation more difficult. It was a CT scan that showed the signs suggestive of exposure to asbestos which raised the diagnostic suspicion. They conclude that every patient with a pleural effusion must be thoroughly questioned about exposure to asbestos. Even if the exposure is accepted, they consider that one should proceed to a pleuro-pulmonar biopsy by thoracoscopy. This biopsy allows demonstration of the characteristic histopathological lesions and rule out other etiologies, namely malignancy and tuberculosis. They suggest that these patients must be highly motivated to stop any smoking and kept under periodic surveillance.

    Results for the effusion and outgassing of tritium from tritiated hydrogenated amorphous silicon (a-Si:H:T) films are presented. The samples were grown by dc-saddle field glow discharge at various substrate temperatures between 150 and 300°C. The tracer property of radioactive tritium is used to detect tritium release. Tritium effusion measurements are performed in a nonvacuum ion chamber and are found to yield similar results as reported for standard high vacuum technique. The results suggest for decreasing substrate temperature the growth of material with an increasing concentration of voids. These data are corroborated by analysis of infrared absorption data in terms of microstructure parameters. For material of low substrate temperature (and high void concentration) tritium outgassing in air at room temperature was studied, and it was found that after 600h about 0.2% of the total hydrogen (hydrogen+tritium) content is released. Two rate limiting processes are identified. The first process, fast tritium outgassing with a time constant of 15h, seems to be related to surface desorption of tritiated water (HTO) with a free energy of desorption of 1.04eV. The second process, slow tritium outgassing with a time constant of 200-300h, appears to be limited by oxygen diffusivity in a growing oxide layer. This material of lowest H stability would lose half of the hydrogen after 60years.

    Background Effusive-constrictive pericarditis (ECP) is traditionally diagnosed by using the expensive and invasive technique of direct pressure measurements in the pericardial space and the right atrium. The aim of this study was to assess the diagnostic role of echocardiography in tuberculous ECP. Methods Intrapericardial and right atrial pressures were measured pre- and post-pericardiocentesis, and right ventricular and left ventricular pressures were measured post-pericardiocentesis in patients with tuberculous pericardial effusions. Echocardiography was performed post-pericardiocentesis. Traditional, pressure-based diagnostic criteria were compared with post-pericardiocentesis systolic discordance and echocardiographic evidence of constriction. Results Thirty-two patients with tuberculous pericardial disease were included. Sixteen had ventricular discordance (invasively measured), 16 had ECP as measured by intrapericardial and right atrial invasive pressure measurements and 17 had ECP determined echocardiographically. The sensitivity and specificity of pressure-guided measurements (compared with discordance) for the diagnosis of ECP were both 56%. The positive and negative predictive values were both 56%. The sensitivity of echocardiography (compared with discordance) for the diagnosis of ECP was 81% and the specificity 75%, while the positive and the negative predictive values were 76% and 80%, respectively. Conclusion Echocardiography shows a better diagnostic performance than invasive, pressure-based measurements for the diagnosis of ECP when both these techniques are compared with the gold standard of invasively measured systolic discordance.

    Mediastinal and subcutaneous emphysema may occur after dental and oral surgery as a result of iatrogenic introduction of air or injury to the tracheobronchial tree. We report a patient who developed emphysema and pneumothorax after dentoalveolar surgery, which made diagnosis and management difficult. We suggest that persistent postoperative vomiting caused inhalation of mediastinal and intrathoracic air.

    To analyze the utility of the measurement of pleural amylase levels (AL) and pleural fluid/serum amylase ratio (AR) in malignant pleural effusions. Prospective and comparative study of AL and its AR in relation to the patient and pleural fluid characteristics in 295 malignant effusions and 673 nonmalignant. There were 103 patients with AL greater than 100 U/l (11%) and 268 with AR greater than 1 (28%): 53 (18%) and 109 (37%) in malignant effusions respectively. Patients with malignant effusions had higher AL and AR, especially when tumour origin was lung cancer, had positive pleural citology or biopsy and showed an adenocarcinoma. Multivariate regression analysis revealed a significant difference in the changes in AL associated with positive pleural citology or biopsy and massive pleural effusion. The malignant effusions had higher AL in lung cancer of stage IV. AL and AR should not be routinely measured to exclude a malignant effusion. A high AL or AR was related to positive pleural citology or biopsy, a massive pleural effusion and lung cancer with an advanced disease.

    Pleural effusion is a common clinical entity. Proper diagnosis and management are important for successful treatment. We undertook this study to evaluate immediate results of the procedures used in a group of cases with pleural effusion. Of 2589 patients at first consultation, 787 were hospitalized and 156 had pleural effusion. Diagnostic and therapeutic procedures used were evaluated. With thoracentesis and evacuation of liquid, 23 nonneoplastic cases had resolution. Chest tube drainage with water seal was performed in 133 patients. This procedure suppressed the effusion in 109 patients, but in 24 patients another approach was necessary. In this group there were 35 neoplastic and 96 nonmalignant cases, the latter 36 were provoked by iatrogenic management. Twenty two cases of pneumothorax considered as gaseous effusion and 10 cases of chronic empyema sequelae of pleural effusions were also studied. Proportion comparison demonstrated significant differences between neoplastic and nonneoplastic effusions (p =0.001) and in cases managed with minimally invasive procedures and chest tube drainage (p =0.001). The performance of pleurodesis and thoracoscopy is discussed. In chronic cases, indications of open window thoracostomy and myoplasty are elucidated. In pleural effusion, opportune diagnosis and proper management are essential. Drainage tube can solve the majority of cases. Pneumothorax must be treated in the same way. In chronic empyema, open window thoracostomy and myoplasty are indicated. Careless patient management and poor treatment lead to iatrogenic complications.

    The differential diagnosis of pleural effusions can present a considerable challenge, and the etiology of pleural effusions varies depending on the population studied. This study aimed to assess the efficacy and safety of medical thoracoscopy in the diagnosis of patients with undiagnosed pleural effusions in a Chinese population. Between July 2005 and June 2014, medical thoracoscopy (MT) using the semirigid instrument was performed in 833 patients with pleural effusions of unknown etiology in our Institute, where diagnostic thoracocentesis or/and blind pleural biopsy had failed to yield an answer. Demographic, radiographic, procedural, and histological data were recorded and analyzed. During this 9-year study, satisfactory pleural biopsy samples were obtained in 833 patients, and MT revealed malignant pleural effusion in 342 (41.1%) patients, benign pleural effusion in 429 (51.5%) patients, and 62 (7.4%) patients could not get definite diagnoses. The overall diagnostic efficiency of MT was 92.6% (771/833). After MT, the only severe complication was empyema, seen in 3 patients (0.4%). The most common minor complication was transient chest pain (44.1%) from the indwelling chest tube. MT is an effective and safe procedure for diagnosing pleural effusions of undetermined causes. In areas with high tuberculosis prevalence, MT should be particularly helpful in the differential diagnosis of tuberculous pleural effusion. © 2015 S. Karger AG, Basel.

    To compare the efficacy of intravitreal bevacizumab (IVB) injection alone or with intravitreal triamcinolone acetonide (IVB/IVT) versus macular photocoagulation (MPC) in bilateral diabetic macular edema (DME). In this study we revisited data from a subset of subjects previously enrolled in a randomized clinical trial. The original study included 150 eyes randomized to three treatment arms: 1.25 mg IVB alone, combined injection of 1.25 mg IVB and 2 mg IVT, and focal or modified grid MPC. To eliminate the possible effects of systemic confounders, we selected fellow eyes of bilaterally treated subjects who had undergone different treatments; eventually 30 eyes of 15 patients were re-evaluated at baseline, 6, 12, 18, and 24 months. Using mixed model analysis, we compared the treatment protocols regarding visual acuity (VA) and central macular thickness (CMT). Improvement in VA in the IVB group was significantly greater compared to MPC at months 6 and 12 (P = 0.037 and P = 0.035, respectively) but this difference did not persist thereafter up to 24 months. Other levels of VA were comparable at different follow-up intervals (all P > 0.05). The only significant difference in CMT was observed in favor of the IVB group as compared to IVB/IVT group at 24 months (P = 0.048). Overall VA was superior in IVB group as compared to MPC up to 12 months. Although the IVB group showed superiority regarding CMT reduction over 24 months as compared to IVB/IVT group, it was comparable to the MPC group through the same period of follow up.

    Objective The aim of our study was to evaluate the role of 18F-FDG PET/CT integrated imaging in differentiating malignant from benign pleural effusion. Methods A total of 176 patients with pleural effusion who underwent 18F-FDG PET/CT examination to differentiate malignancy from benignancy were retrospectively researched. The images of CT imaging, 18F-FDG PET imaging and 18F-FDG PET/CT integrated imaging were visually analyzed. The suspected malignant effusion was characterized by the presence of nodular or irregular pleural thickening on CT imaging. Whereas on PET imaging, pleural 18F-FDG uptake higher than mediastinal activity was interpreted as malignant effusion. Images of 18F-FDG PET/CT integrated imaging were interpreted by combining the morphologic feature of pleura on CT imaging with the degree and form of pleural 18F-FDG uptake on PET imaging. Results One hundred and eight patients had malignant effusion, including 86 with pleural metastasis and 22 with pleural mesothelioma, whereas 68 patients had benign effusion. The sensitivities of CT imaging, 18F-FDG PET imaging and 18F-FDG PET/CT integrated imaging in detecting malignant effusion were 75.0%, 91.7% and 93.5%, respectively, which were 69.8%, 91.9% and 93.0% in distinguishing metastatic effusion. The sensitivity of 18F-FDG PET/CT integrated imaging in detecting malignant effusion was higher than that of CT imaging (p = 0.000). For metastatic effusion, 18F-FDG PET imaging had higher sensitivity (p = 0.000) and better diagnostic consistency with 18F-FDG PET/CT integrated imaging compared with CT imaging (Kappa = 0.917 and Kappa = 0.295, respectively). The specificities of CT imaging, 18F-FDG PET imaging and 18F-FDG PET/CT integrated imaging were 94.1%, 63.2% and 92.6% in detecting benign effusion. The specificities of CT imaging and 18F-FDG PET/CT integrated imaging were higher than that of 18F-FDG PET imaging (p = 0.000 and p = 0.000, respectively), and CT imaging had better diagnostic consistency with

    Intraarticular volumes were measured by radiolabeled albumin (RISA) distribution in chronic knee effusions from 11 rheumatoid arthritis patients and 9 osteoarthritis patients. Volumes of synovial fluid obtained at joint aspiration were substantially less than those found by RISA dilution. Up to 24 hours was needed for full distribution of RISA throughout the intraarticular compartment. Measured 123I and RISA radioactivity over the knee described monoexponential rate constants, lambda (minute-1). The clearance of 123I and RISA from synovial effusions was derived by the formulation volume (ml) X lambda (minute-1) = clearance (ml/minute). RISA clearance in rheumatoid effusions was significantly greater than that found in osteoarthritis effusions. Intraarticular volume and isotope clearance were easily quantified and provide measures for further evaluating the microvascular physiology of synovial effusions.

    In order to discriminate between benign and malignant effusions, the value of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and beta subunit of human chorionic gonadotropin (GNCH Sub-beta) has been estimated in pleural exudates. A sample of 65 patients, 33 with a malignant (histologically and/or cytologically established) and 32 with a benign effusion was analysed. Only mean CEA in malignant effusions was significantly higher than in benign effusions (p less than 0.01). In the detection of malignant effusion CEA showed a sensitivity of 57% and a specificity of 97%; AFP a sensitivity of 9% and a specificity of 97% and GNCH Sub beta a sensitivity of 9% and a specificity of 90%.

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge.

    Malignant effusions offer a unique opportunity for the study of interactions between the human immune system and cancer. We have recently demonstrated that malignant effusions are characterized by an accumulation of T cells expressing chemokine receptors such as CCR4, which is commonly found on Th2 cells. In contrast, effector T cells expressing chemokine receptors typical for Th1 cells, such as CCR5, showed a diminished homing into malignant effusions. We analyzed concentrations of 12 different cytokines and 9 chemokines within malignant and nonmalignant effusions and investigated cytokine expression by effusion-infiltrating leukocytes. We observed that concentrations of the immunoregulatory cytokine TGF-beta(1) and of angiogenic factors VEGF and IL-8 were markedly increased within effusions caused by malignancies. However, we did not observe signs of a typical Th1 or Th2 milieu. Analyzing concentrations of 9 different chemokines, we found elevated concentrations of the chemokines MDC, eotaxin, I-TAC, and MCP-1 in malignant effusions. Interestingly, tumor-infiltrating leukocytes themselves seemed to contribute strongly to the creation of a distinct cytokine/chemokine pattern within cancer-related effusions. Additional analyses suggested that this cytokine/chemokine milieu might support an enrichment of immunosuppressive leukocytes. The local cytokine and chemokine milieu within malignant effusions seems to promote angiogenesis and to block an efficient immune-mediated antitumor response. An elimination of such tumor-promoting influences will be necessary in order to transform local immunotolerance into clinically relevant immune recognition of tumors causing malignant effusions.

    Glucose transporter 1 (GLUT1) is a hallmark of metabolic change in cancer cells. The objective of this study was to determine the role of GLUT1 protein in diagnosing malignant pleural effusions by enzyme-linked immunosorbent assay (ELISA) and immunocytochemistry. In total, 82 pleural effusions were collected and classified as benign (n = 42), atypical (n = 8), or malignant (n = 32) based on cytologic diagnosis and etiology. GLUT1 protein levels in effusions were measured by ELISA. GLUT1 expression also was determined by immunocytochemistry using cell blocks. GLUT1 levels were significantly higher in the malignant group compared with the benign group. Receiver operating characteristic curve analysis of benign and malignant pleural effusions for GLUT1 yielded an area under the curve of 0.77, with a value of 1355.87 pg/dL as the optimal threshold for distinguishing benign from malignant effusions. With the ELISA method, the sensitivity, specificity, and accuracy were 78.1%, 69%, and 73%, respectively. Malignant effusion cell blocks were positive for GLUT1 expression in 84.4% of cases with 100% specificity and 93.2% accuracy. With the combination of high GLUT1 protein levels (>10,000 pg/dL) and immunocytochemistry to detect malignant pleural effusions, the sensitivity and accuracy increased to 93.8% and 94.6%, respectively. The GLUT1 level measured by ELISA and the GLUT1 expression detected by immunocytochemistry were positively correlated. In atypical effusions, 3 cases (37.5%) had GLUT1 levels higher than the cutoff value. The detection of GLUT1 protein by ELISA and immunocytochemistry may have utility in the diagnosis of malignant pleural effusions. © 2013 American Cancer Society.

    Headspace solid-phase microextraction (HS-SPME) combined with gas chromatography/mass spectrometry (GC/MS) method was applied for the investigation of low molecular weight volatile organic metabolites (VOMs) in pleural effusion samples. Three important HS-SPME experimental parameters that influence extraction efficiency (fiber coating, extraction time and temperature of sampling) were optimized by a univariate optimization design. The highest extraction efficiency was obtained when sampling was performed at 50°C for 10min under agitation using a carboxen/polydimethylsiloxane (CAR/PDMS) fiber. A total of 36 volatile metabolites belonging to nine distinct chemical classes were identified in 40 pleural effusion samples (20 malignant effusions from lung cancer patients and 20 benign effusions from inflammatory patients). Ketones, alcohols, and benzene derivatives were the main chemical classes for the metabolomic profile of malignant effusions. The average peak areas of ketones and alcohols were much higher in malignant group compared to benign group. Together with phenols, they exhibit significant differences (P<0.05) between the two groups. Particularly, the average peak areas of cyclohexanone and 2-ethyl-1-hexanol in malignant effusions were significantly higher than those in benign ones. Furthermore, of the 36 identified metabolites, 5 compounds including cyclohexanone and 2-ethyl-1-hexanol were found to be statistically different (Student's t-test, P<0.05) between the two groups by statistical analysis based on the peak areas of all identified metabolites. Among them, cyclohexanone and 2-ethyl-1-hexanol might be considered as candidate biomarkers of lung cancer to differentiate malignant from benign effusions. The results show that HS-SPME-GC/MS is a simple, rapid, sensitive and solvent-free method for the determination of VOMs in pleural effusion samples. Pleural effusion is a valuable sample source for observation of changes in VOMs for differentiation between

    Langerhans cell histiocytosis is a rare disorder, with resultant bilateral sensorineural hearing loss unreported in adults. A 42-year-old man presented with 4 months of right-sided tinnitus and hearing loss treated initially as otitis media with effusion. He re-presented 5 months later with progressive bilateral hearing loss—sensorineural (>100 dB) on pure tone audiogram. CT showed bilateral petrous temporal bone and calvarial lesions. Biopsy confirmed diagnosis of Langerhans cell histiocytosis and chemotherapy was started. Though uncommon, Langerhans cell histiocytosis should be considered among the differentials of persistent otological symptoms, as its progressive nature can cause bilateral irreversible sensorineural hearing loss.

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

    Malignant pleural effusions cause significant morbidity, but there is no gold standard minimally invasive treatment. A new therapeutic approach combines talc pleurodesis and indwelling pleural catheters (IPCs) to enable outpatient management. This case series summarizes the safety and efficacy data of all patients (24) with a symptomatic malignant pleural effusion who underwent talc pleurodeses via IPCs between December 2010 and July 2013. Successful pleurodesis was achieved in 22 procedures (92%). There was one empyema, one hydropneumothorax, one recurrent effusion, and two minor complications: one drain site wound infection and one complaint of chest pain. Twenty-two procedures (92%) were performed in the outpatient setting. This report confirms the safety and efficacy of administering talc slurry through IPCs in an outpatient setting. Studies in a larger cohort are necessary to define the role of this novel approach in the treatment algorithm of patients with this condition.

    RED-SEED stands for Risk Evaluation, Detection and Simulation during Effusive Eruption Disasters, and combines stakeholders from the remote sensing, modeling and response communities with experience in tracking volcanic effusive events. It is an informal working group that has evolved around the philosophy of combining global scientific resources, in the realm of physical volcanology, remote sensing and modeling, to better define and limit uncertainty. The group first met during a three day-long workshop held in Clermont Ferrand (France) between 28 and 30 May 2013. The main recommendation of the workshop in terms of modeling was that there is a pressing need for "real-time input of reliable Time-Averaged Discharge Rate (TADR) data with regular up-dates of Digital Elevation Models (DEMs) if modeling is to be effective; the DEMs can be provided by the radar/photogrammetry community." We thus set up a test to explore (i) which model source terms are needed, (ii) how they can be provided and updated, and (iii) how can models be run and applied in an ensemble approach. The test used two hypothetical effusive events in the Chaîne des Puys (Auvergne, France), for which a prototype Geographical Information System (GIS) was set up to allow loss assessment during an effusive crisis. This system drew on all immediately available data for population, land use, communications, utility and building-type. After defining lava flow model source terms (vent location, effusion rate, lava chemistry, temperature, crystallinity and vesicularity), five operational lava flow emplacement models were run (DOWNFLOW, FLOWGO, LAVASIM, MAGFLOW and VOLCFLOW) to produce a projection for likelihood of impact for all pixels within the area covered by the GIS, based on agreement between models. The test thus aimed not to assess the model output, but instead to examine overlapping output. Next, inundation maps and damage reports for impacted zones were produced. The exercise identified several

    Involvement of the pleura in lung cancer is a common manifestation accompanying with reduced life expectancy. Symptoms relief and improvement of the quality of life are the primary goals of the management of malignant pleural effusion (MPE). Histological confirmation is essential for optimal patient management. Lung cancer patients, with life expectancy more than 3 months, resistant to chemotherapy should be treated with thoracentesis, intercoastal tube drainage and installation of a sclerosant agent or pleurodesis through thoracospopic procedures or placement of an indwelling pleura catheter. Talc pleurodesis (sterile asbestos-free graded, particle size >15 μm), as “poudrage” or “slurry” still remains the treatment of choice in patients with MPE resistant to chemotherapy. PMID:24102015

    Active open-conduit basaltic volcanoes that demonstrate a wide range of eruptive styles have attracted the interest of the scientific community for decades. Of these volcanoes, Stromboli, in the Aeolian island chain (Italy) is one of the most well investigated and monitored. Its persistent explosive activity and relatively frequent effusive eruption, represent an ideal 'laboratory' for the study of steady state magma supply and eruptive dynamics. On 7 August 2014, after a period of intense overflow episodes, an eruptive fissure opened at the base of the North-east cone supplying a large lava-flow which spread down-hill the Sciara del Fuoco. Here, we report on remote sensing observations of SO2 flux and SO2/HCl and HF molar ratio collected by means of an SO2 camera, the FLAME scanning network and the permanent FTIR system CERBERUS. Geochemical data are compared with volcanic seismic tremor.

    A versatile Knudsen type effusion cell has been fabricated for growing nanostructures and epitaxial layers of metals and semiconductors. The cell provides excellent vacuum compatibility (10{sup -10} mbar range during operation), efficient water cooling, uniform heating, and moderate input power consumption (100 W at 1000 deg. C). The thermal properties of the cell have been determined. The performance of the cell has been assessed by x-ray photoemission spectroscopy (XPS) for Mn adlayer growth on Al(111). We find that this Knudsen cell has a stable deposition rate of 0.17 monolayer per minute at 550 deg. C. From the XPS spectra, we show that the Mn adlayers are completely clean, i.e., devoid of any surface contamination.

    Malignant pleural effusion (MPE) is the lethal consequence of various human cancers metastatic to the pleural cavity. However, the mechanisms responsible for the development of MPE are still obscure. Here we show that mutant KRAS is important for MPE induction in mice. Pleural disseminated, mutant KRAS bearing tumour cells upregulate and systemically release chemokine ligand 2 (CCL2) into the bloodstream to mobilize myeloid cells from the host bone marrow to the pleural space via the spleen. These cells promote MPE formation, as indicated by splenectomy and splenocyte restoration experiments. In addition, KRAS mutations are frequently detected in human MPE and cell lines isolated thereof, but are often lost during automated analyses, as indicated by manual versus automated examination of Sanger sequencing traces. Finally, the novel KRAS inhibitor deltarasin and a monoclonal antibody directed against CCL2 are equally effective against an experimental mouse model of MPE, a result that holds promise for future efficient therapies against the human condition.

    Malignant pleural effusion (MPE) is a common but serious condition that is related with poor quality of life, morbidity and mortality. Its incidence and associated healthcare costs are rising and its management remains palliative, with median survival ranging from 3 to 12 months. During the last decade there has been significant progress in unravelling the pathophysiology of MPE, as well as its diagnostics, imaging, and management. Nowadays, formerly bed-ridden patients are genotyped, phenotyped, and treated on an ambulatory basis. This article attempts to provide a comprehensive overview of current advances in MPE from bench to bedside. In addition, it highlights unanswered questions in current clinical practice and suggests future directions for basic and clinical research in the field. Copyright ©ERS 2016.

    Lymphocytic pleurisy is commonly observed in tuberculosis and cancer. Noninvasive biomarkers are needed to distinguish tuberculous pleural effusion (TPE) from malignant pleural effusion (MPE) because current clinical diagnostic procedures are often invasive. We identified immune response biomarkers that can discriminate between TPE and MPE. Fourteen pleural effusion biomarkers were compared in 22 MPE patients and five TPE patients. Of the innate immunity biomarkers, the median levels of interleukin (IL)-1β and interferon-induced protein-10 (IP-10) were higher in TPE patients than in MPE patients (P<0.05 and P<0.01, respectively). Of the adaptive immunity biomarkers, the median levels of IL-13 and interferon-γ (IFN-γ) were higher in TPE patients than in MPE patients (P<0.05). In addition, the levels of basic fibroblast growth factor were higher in MPE patients than in TPE patients (P<0.05). Receiver operator characteristic analysis of these biomarkers was performed, resulting in the highest area under the curve (AUC) for IP-10 (AUC =0.95, 95% confidence interval, P<0.01), followed by IL-13 (AUC =0.86, 95% confidence interval, P<0.05). Our study shows that five biomarkers (IL-1β, IP-10, IFN-γ, IL-13, and basic fibroblast growth factor) have a potential diagnostic role in differentiating TPE from MPE, particularly in lung cancer-related MPE.

    On a global scale, tuberculosis (TB) remains one of the most frequent causes of pleural effusions. Our understanding of the pathogenesis of the disease has evolved and what was once thought to be an effusion as a result of a pure delayed hypersensitivity reaction is now believed to be the consequence of direct infection of the pleural space with a cascade of events including an immunological response. Pulmonary involvement is more common than previously believed and induced sputum, which is grossly underutilised, can be diagnostic in approximately 50%. The gold standard for the diagnosis of tuberculous pleuritis remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli (AFB). In high burden settings, however, the diagnosis is frequently inferred in patients who present with a lymphocytic predominant exudate and a high adenosine deaminase (ADA) level, which is a valuable adjunct in the diagnostic evaluation. ADA is generally readily accessible, and together with lymphocyte predominance justifies treatment initiation in patients with a high pre-test probability. Still, false-negative and false-positive results remain an issue. When adding closed pleural biopsy to ADA and lymphocyte count, diagnostic accuracy approaches that of thoracoscopy. The role of other biomarkers is less well described. Early pleural drainage may have a role in selected cases, but more research is required to validate its use and to define the subpopulation that may benefit from such interventions.

    The objective of this study was to evaluate the role of biceps tendon sheath effusion detected on ultrasound as a diagnostic clue to rotator cuff pathology. Despite being the most common cause of shoulder pain in adults early sonographic changes of rotator cuff tendinopathy are easy to miss. A total of 31 patients out of whom 27 had unilateral shoulder pain and 4 had bilateral complaints under- went ultrasonographic examination of shoulder joint using high frequency linear array transducer. Any fluid surrounding the long head of biceps tendon was noted followed by a careful search for any associated sonographic abnormality involving the rotator cuff. Eighteen out of the 35 had presence of fluid in their biceps tendon sheath. Twelve had presence of both biceps tendon sheath effusion and rotator cuff pathologies. Among 17 patients, who had no fluid in their biceps tendon sheath, only 2 had rotator cuff involvement whereas rest 15 had neither biceps tendon sheath fluid nor rotator cuff pathologies. A significant association was found between presence of fluid in long head of biceps tendon sheath and rotator cuff pathologies. Thus the most common finding observed in association with the presence of fluid around the long head of biceps tendon sheath in this study was tendinosis of rotator cuff. On ultrasonography simple presence of fluid around the long head of biceps tendon sheath demands careful examination of rotator cuff.

    The cause of exudative pleural effusion cannot be determined in some patients. The longterm outcomes of patients with undiagnosed pleural effusion were analyzed. Patients with exudative pleural effusion whose diagnostic procedures included pleural biopsy using video-assisted thoracoscopic surgery carried out between 2008 and 2012 were evaluated retrospectively. Patients diagnosed with non-specific pleuritis were included. Fifty-three patients with available follow-up data were included in the study. Forty men and 13 women (mean age 53.9±13.9 years) were included. Median follow-up time was 24 months. No diagnosis was given in 27 patients (51%), and a clinical diagnosis was given in 26 patients (49%) during the follow-up period. Malignant disease (malignant mesothelioma) was diagnosed in 2 (3.7%) patients. Other diseases were parapneumonic effusion in 12, congestive heart failure in 8, and miscellaneous in 4 patients. Volume of effusion at the time of initial examination and re-accumulation of fluid after video-assisted thoracoscopic surgery were associated with malignant disease (P=.004 and .0001, respectively). Although the probability is low, some patients with exudative pleural effusion undiagnosed after pleural biopsy via video-assisted thoracoscopic surgery may have malignant disease. Patients with an initially large volume of effusion that re-accumulates after examination should be closely monitored. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

    Pulmonary manifestations have been well described in leukemia, but pleural disease is less common. This review highlights pleural effusions in acute and chronic leukemia and myelodysplastic syndrome (MDS) based on the evidence to date. Diagnostic workup and recommendations for the management of these effusions are also outlined. Pleural effusions in patients with leukemia are most often due to infection and to a lesser extent leukemic infiltration of the pleura. The prognostic implications of these effusions are unclear, but survival is most likely determined by the underlying malignancy and its response to treatment. New therapies have changed survival in these patients, and some of these treatments, such as tyrosine kinase inhibitors, have emerged as important causes for these effusions. Pleural interventions may be accomplished with few complications. Pleural effusions may occur with acute and chronic leukemia and MDS. Infection remains the most common cause. Malignant pleural effusions tend to occur in advanced disease in chronic leukemia, but they can be seen at any time with acute leukemia and MDS. With standard precautions, pleural procedures may be performed safely in this population. In cases of unclear cause, pleural and bone marrow biopsy should be considered.

    We report the case of a 47-year old Caucasian man with a history of depression and high alcohol intake who presented with a one-month history of weight loss, dry cough and abdominal pain. He had no smoking history of note. The patient was treated for a suspected chest infection, however developed respiratory failure and was intubated. A CT showed multiple pulmonary nodules, left pleural thickening extending to the mediastinum and bilateral pleural effusions-larger on the left, suggestive of disseminated malignancy. A broncho-alveolar lavage surprisingly contained numerous acid-fast bacilli and no malignant cells. Treatment for tuberculosis was initiated and the patient recovered gradually. After several weeks, a pyrazinamide-resistant organism was cultured and subsequently identified to be Mycobacterium Bovis. We discuss this unexpected finding and review the literature on Bovine Tuberculosis in humans.

    A 78-year-old man with cryptogenic chronic bilateral lymphoplasmacytic pleuritis, diagnosed based on left parietal pleural biopsy specimens obtained by pleuroscopy, developed acute left bacterial pleuritis. The left pleural effusion was neutrophil dominant, however, the right pleural effusion showed lymphoplasmacytic infiltration. Laboratory examinations revealed that his serum IgG4 concentration was increased, with a higher level of IgG4 in the right pleural effusion. Re-evaluation of the previous biopsy specimens using an immunostaining method revealed numerous IgG4-positive plasma cell infiltrations with IgG4-positive/IgG-positive plasma cells at 85.4%. Accordingly, the new diagnosis of this patient was considered to be chronic bilateral IgG4-related pleuritis.

This patient's angle closure was thought to be caused by idiopathic uveal effusion syndrome, and while there are no generally accepted diagnosis criteria for nanophthalmos, our patient fulfilled the criteria as defined by Wu.10 To prevent development of further angle closure, the decision was made to do cataract extraction as opposed to medical management.

    Thermal properties of several vegetable oils such as soy, corn, and avocado commercial oils were obtained by using a photopyroelectric technique. The inverse photopyroelectric configuration was used in order to obtain the thermal effusivity of the oil samples. The theoretical equation for the photopyroelectric signal in this configuration, as a function of the incident light modulation frequency, was fitted to the experimental data in order to obtain the thermal effusivity of these samples. The obtained results are in good agreement with the thermal effusivity reported for other vegetable oils. All measurements were done at room temperature.

    Middle ear (ME) pressures were measured in 30 children with chronic otitis media with effusion (OME) transtubally with the use of a catheter pressure transducer (Mikro-tip, PC-330F). They were found to range from 40 to -185 mm H2O, the average being mildly negative (-54.33 +/- 59.04 mm H2O). About two thirds of these children had pulsating changes of ME pressure; the range of the pressure change was between 10 and 50 mm H2O. The ME pressure tended to be lower in ears with serous effusion than in those with mucoid effusion, but there was no significant difference between them.

    Malignant pleural effusions (MPEs) are the second leading cause of exudative pleural effusions after parapneumonic effusions. In the vast majority of cases, a MPE signifies incurable disease associated with high morbidity and mortality. Considerable advances have been made for the diagnosis of MPEs, through the development of improved methods in the specialized cytological and imaging studies. The cytological or histological confirmation of malignant cells is currently important in establishing a diagnosis. Furthermore, despite major advancements in cancer treatment for the past two decades, management of MPE remains palliative. This article presents a comprehensive review of the medical approaches for diagnosis and management of MPE. PMID:24920947

    2011-06-01

    Malignant pleural effusions (MPEs) affect > 150,000 people each year in the United States. Current palliative options include pleurodesis and placement of an indwelling catheter, each with its own associated benefits. This study was conducted to determine the safety, efficacy, and feasibility of a rapid pleurodesis protocol by combining medical thoracoscopy with talc pleurodesis and simultaneous placement of a tunneled pleural catheter (TPC) in patients with symptomatic MPE. Patients with recurrent, symptomatic MPEs underwent medical thoracoscopy with placement of a TPC and talc poudrage. The TPC was drained per protocol until the output was < 150 mL/d on two consecutive drainage attempts and then removed. Patients were followed for up to 6 months. Between October 2005 and September 2009, 30 patients underwent the procedure. The median duration of hospitalization following the procedure was 1.79 days. All patients showed an improvement in dyspnea and quality of life. Pleurodesis was successful in 92% of patients, and the TPC was removed at a median of 7.54 days. Complications included fever (two patients), the need for TPC replacement (one patient), and empyema (one patient). Rapid pleurodesis can be achieved safely by combining medical thoracoscopy and talc poudrage with simultaneous TPC placement. Both hospital length of stay and duration of TPC use can be reduced significantly as compared with historical controls of either procedure alone. Future randomized trials are needed to confirm these results.

    Objectives: To assess the utility of the cell block preparation method in increasing the sensitivity of cytodiagnosis of serous fluids and to know the primary site of malignant effusions. Materials and Methods: A total of 190 cases were subjected to routine smear examination as well as cell block preparation. After the cytological diagnosis, each case was objectively analysed for cellularity, arrangement (acini, papillae, cell balls, and proliferation spheres), cytoplasmic, and nuclear details. Results: Out of 190 cases, 70 cases were found to be malignant and had been examined in smears and paraffin-embedded cell blocks. Using a combination of the cell block and smear techniques yielded 13% more malignant cases than what were detected using smears by themselves. The combined technique helped to ascertain the primary site of malignancy in 83.3% of the cases, whereas the primary site could not be ascertained in 17.7% of the cases. Conclusions: The cell block technique not only increased the positive results, but also helped to demonstrate better architectural patterns, which could be of great help in making correct diagnosis of the primary site. The cell block technique was also useful for special stains and immunohistochemistry and can give morphological details by preserving the architectural patterns. PMID:21938154

    2016-01-01

    Background Malignant pleural effusions (MPEs) represent advanced stage disease with potentially significant patient discomfort due to dyspnea. Palliative management options include repetitive thoracenteses, placement of a tunneled pleural catheter (TPC), chemical pleurodesis, or some combination of these procedures. The rapid pleurodesis procedure combines thoracoscopic talc pleurodesis and insertion of a TPC at the same time with the goals of reducing both the length of hospitalization and the duration of catheter use. The rapid pleurodesis procedure has previously been described to achieve both of these goals in a pilot study of 30 patients with fully expandable lungs. Both symptoms of dyspnea and quality of life improved with few complications. Additional data on procedural effectiveness is needed to optimize patient selection for this procedure. Methods We performed a retrospective analysis of patients who had undergone rapid pleurodesis protocol at two academic institutions over a 40-month period. Data was collected and analyzed on time to removal of the TPC, chemotherapy, malignancy type, complications, age, and catheter occlusion. Results A total of 29 patients underwent the rapid pleurodesis protocol with a median hospital length of stay of 2 days. Total length of hospitalization was not significantly different between patients with and without primary lung cancer. Median duration of the indwelling TPC was 10 days. Patients with primary lung cancer and those actively or recently undergoing chemotherapy maintained the catheter longer than their counterparts. Conclusions The rapid pleurodesis protocol should be considered a viable treatment option for select patients with symptomatic recurrent MPEs undergoing chemical pleurodesis. PMID:27747006

    We performed this study to determine sensitivity and specificity of pleural effusion antinuclear antibodies (ANA) at a titer of ≥1 : 160, and the ratio of pleural effusion to serum ANA of ≥1, to distinguish between pleural fluid from lupus pleuritis and other causes. A prospective study of 54 patients with pleural effusion (12 lupus pleuritis, seven parapneumonic effusion, 26 malignancy-associated pleural effusions, nine transudative effusions) was performed. ANA at a titer of ≥1 : 160 were found in 11 of 12 lupus pleuritis samples, and in four of 42 pleural effusions from non-systemic lupus erythematosus (SLE) patients. The pleural effusion ANA at a titer of ≥1 : 160 gave a sensitivity of 91.67% for lupus pleuritis, with a specificity of 83.33% when compared with all other pleural effusions, 90.91% when compared with exudative effusion (parapneumonic effusion and malignancy-associated effusion) and 55.56% when compared with the transudative pleural effusion group. Using the ratio of pleural effusion to serum ANA of ≥1, the sensitivity and the specificity decreased to 75.00% and 78.57%, respectively. This study provides further evidence that the pleural effusion ANA at a titer of ≥1 : 160 is a sensitive and specific diagnostic biomarker for lupus pleuritis in patients with lupus. However, pleural effusion ANA can occasionally be found in other conditions.

    A lava emission started at Mt. Etna, Italy, on 7 September, 2004. Neither earthquake seismicity heralded or accompanied the opening of the fracture field from which the lava poured out, nor volcanic tremor changed in amplitude and frequency content at the onset of the effusive activity. To highlight long-term changes, we propose a method for the location of the tremor source based on a 3D grid search, using the amplitude decay of the seismic signal, from January to November 2004. We find the centroid of the tremor source within a zone close to and partially overlapped with the summit craters (pre-effusive phase), which extended up to 2 km south of them (effusive phase). The depths are of between 1698 and 2387 m a.s.l. We hypothesize the lava effusion stemmed from a degassed magma body, although we find evidence of temporary magma overpressure conditions, such as those documented on 25 September.

    The occurrence of pancreatic pleural effusion, secondary to an internal pancreatic fistula, is a rare clinical syndrome and diagnosis is often missed. The key to the diagnosis is a dramatically elevated pleural fluid amylase. This pancreatic pleural effusion is also called a pancreatic pleural fistula. It is characterized by profuse pleural fluid and has a tendency to recur. Here we report a case of delayed internal pancreatic fistula with pancreatic pleural effusion emerging after splenectomy. From the treatment of this case, we conclude that the symptoms and signs of a subphrenic effusion are often obscure; abdominal computed tomography may be required to look for occult, intra-abdominal infection; and active conservative treatment should be carried out in the early period of this complication to reduce the need for endoscopy or surgery.

    The surgeon's objectives are normal nasolabial appearance and normal speech. The principles for synchronous repair of bilateral cleft lip have been established, and the techniques continue to evolve. Primary repair impairs maxillary growth, but little can be done at this time except to practice gentle craftsmanship and to minimize tension on the lower labial closure. The cutaneous lip should never be reopened for revision, and the number of secondary procedures involving the nasal cartilages should be kept to a minimum. Many adolescents with repaired bilateral cleft lip need maxillary advancement to improve projection of the nasal tip, to protrude the upper lip, and to attain normal sagittal skeletal harmony. With expected improvements in the technology of distraction osteogenesis, maxillary advancement may someday become as acceptable as orthodontic treatment.

    The author reports the case of a well and fit patient who presented herself to the emergency department and was found to have bilateral emphysematous pyelonephritis. She was admitted to the intensive care where she was initially treated conservatively with antibiotics, percutaneous drainage and continuous renal replacement therapy, but her condition deteriorated. She underwent a left total nephrectomy and a partial right nephrectomy that resulted in remarkable improvement. The patient started passing urine spontaneously, so no haemofiltration was required. She was discharged home and her case was followed-up by an urologist and nephrologist. This case lays emphasis on thoroughly investigating and managing a patient with bilateral emphysematous pyelonephritis and, in relation to its management, on the dilemma of whether the treatment of choice should be conservative or surgical.

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor.

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    Renal Lymphangiectasia (RLM) is very rare benign lymphatic malformation. It can be misdiagnosed for other cystic renal masses, most commonly polycystic kidneys. Though incidentally found in most cases, it may be the cause for hypertension and renal failure in undiagnosed patients. Here, we report a case of an adult asymptomatic male with bilateral RLM which was detected as an incidental finding on ultrasound. Confirmation by CT-scan and laboratory diagnosis of aspirated fluid was done, and patient was managed conservatively.

    Introduction: Diagnostic approaches to patients with a pleural effusion must be precise because many procedures depend on the nature of the fluid in the effusion. To date, no biochemical test is considered an appropriate alternative to Light’s criteria. This study compared the absolute pleural cholesterol (PC) level and the pleural cholesterol/serum cholesterol (PC/SC) ratio with Light’s criteria to determine exudative pleural effusions. Materials and Methodology: This study was a case series of 100 consecutive patients with pleural effusions. The clinical parameters that were used to diagnosis an exudative effusion included the cholesterol level, a pleural cholesterol level ≥ 50 mg/dL, a pleural/serum ratio ≥ 0.4, and Light’s criteria. The sensitivity, specificity, and positive and negative predictive values of each test for the diagnosis of an exudative effusion were assessed. Results: A total of 79 patients were definitively diagnosed with an exudative effusion and were included in the trial and analyzed. The mean PC level in the exudates was 90.39 mg/dL. The PC levels demonstrated a sensitivity of 97.22%, a specificity of 85.71%, a positive predictive value of 98.59% and a negative predictive value of 75%. The PC/SC ratio demonstrated a sensitivity of 81.48%, a specificity of 57.14%, a positive predictive value of 93.61% and a negative predictive value of 28.57%. Conclusion: The pleural cholesterol dosage level and the pleural/serum cholesterol ratio can be utilized as unique biomarkers to identify an exudative effusion and replace Light’s criteria.

    A patient with uncontrolled primary open-angle glaucoma underwent selective laser trabeculoplasty and developed a significant anterior chamber reaction, shallow anterior chamber, and choroidal effusion. Common complications associated with selective laser trabeculoplasty include conjunctival injection, mild anterior chamber reaction, and post-treatment intraocular pressure elevation. The authors believe this is the first reported case of severe iritis and choroidal effusion following selective laser trabeculoplasty.

    To differentiate reactive mesothelial cells (RMs) from metastatic carcinoma and malignant mesothelioma (MM) in effusion cytology is crucial for the cytologic diagnosis and the management of the patients. In the present study, the immunocytochemical staining profile of the epithelial membrane antigen (EMA), the insulin-like growth factor-II mRNA-binding protein 3 (IMP3), and the glucose transporter-1 (GLUT-1) was examined to distinguish RMs from malignant cells. A total of 171 pleural (n = 87) and peritoneal (n = 84) effusion specimens, including 50 benign effusions with RMs, 11 MM effusions, and 110 metastatic malignant effusions, were evaluated for immunocytochemistry. EMA, IMP3, monoclonal GLUT-1, and polyclonal GLUT-1 immunoreactivity were observed in 26.0%, 6.0%, 20.0%, and 18.0% of RMs, respectively. In contrast to RMs, the immunoreactivity in MM was 100%, 36.4%, 100%, and 90.9%; adenocarcinoma (AC) was 100%, 80.8%, 81.7%, and 72.1%; squamous-cell carcinoma was 83.3%, 83.3%, 83.3%, and 66.7%. EMA, IMP3, mGLUT-1, and pGLUT-1 expressions were observed in 98.4%, 65.6%, 88.5%, and 75.4% in the pleural effusion with malignant cells, and 100%, 88.3%, 78.3%, and 71.7% in ascites containing malignant cells, respectively. The findings of the present study indicate that the immunocytochemical staining for EMA, IMP3, and GLUT-1 is a useful diagnostic tool for distinguishing effusions containing malignant cells from those that contain benign cells, and in particular, we suggest that the combination of mGLUT-1 and EMA, and IMP3 and EMA are extremely useful in pleural effusion and in ascites, respectively.

    Abstract Background: Although hyperthermic intraperitoneal chemotherapy (HIPEC) has been widely used to treat malignant ascites or as a preventive strategy for microscopic carcinomatosis following surgical resection of abdominal tumors, application of hyperthermic intrathoracic chemotherapy (HITHOC) in the treatment of malignant pleural effusion is limited. The objective of the current study was to conduct a systematic review and meta-analysis on the application of HITHOC in the palliative treatment of malignant pleural effusion. Methods: After thorough searching of online databases, total 27 articles were included into qualitative systematic review and 5 of them were used to conduct qualitative meta-analysis. Results: It was found that most of HITHOC was used in combination of cytoreductive surgery (CRS) including pleurectomy/decortication or after surgical resection of primary tumors, which mainly were lung cancer, thymoma or thymic carcinoma, breast cancer, and ovarian cancer. Patients who received HITHOC had significantly longer median survival length compared to the patients without HITHOC (Hedges g = 0.763, P < 0.001). In addition, HITHOC therapy was favored (Hedges g = 0.848, P < 0.001) in terms of median survival length, tumor-free survival rate, with tumor survival rate or Karnofsky performance status (KPS) scale. Conclusion: HITHOC is a safe and effective therapy in controlling pleural effusion and increasing patient's survival rate. PMID:28072694

  20. Analysis of The Xx Century Effusive Activity At Mount Etna To Assess The Potential Effusive Hazard.

    Andronico, D.; Lodato, L.; Neri, M.

    We examined older documents and publications together with more recent and de- tailed reports related to the 20th century effusive activity (terminal and flank eruptions) at Mt. Etna, with the primary objective of creating a single data-base of volcanologi- cal data, at present lacking in the literature. The restitution in digital form of the maps of the lava fields allowed to measure, with great precision compared with previous estimations, the area and length of every lava flow, allowing improved estimates of volumes and effusive rates. The quantity and the quality of the collected bibliographic information of the studied eruptions improve progressively from the beginning of the century up to the present, and can be considered complete for the flank activity. The data of each single eruption have been inserted into a relational database, that pro- vides both ease of use and the potential of upgrading with information from new or more ancient eruptions. By examining the collected data (e.g. maximum length of lava flows, altitude reached, eruption duration) we obtained some useful relationships, that allowed us to characterise some eruption typologies at Etna. The improvement of the volcanic data related to the effusive activity of the last century represents an impor- tant contribution in terms of volcanic hazard, suggesting for example the areas most at risk by opening of eruptive fractures and lava covering. Statistical observations can be a useful contribution to the planning required by civil defense in a strongly urban- ized area, such as the etnean one; assessment hazard, in particular, should be focused particularly on the southeastern foot of the volcanic belt, in which the volcanic risk in- creases due to the presence of several populated centers that amount to approximately 500.000 people.

    Biofilms have been implicated in the development of several chronic upper respiratory tract infections. Role of bacterial biofilms has been well studied in the pathogenesis of chronic rhinosinusitis. However, its impact on development of middle ear effusion is still a matter of debate. To study the extent of surface adenoid biofilm and evaluate its role in the pathogenesis of chronic otitis media with effusion in children. The study was carried out on 40 children in Alexandria Main University Hospital between 1 and 16 years of age without sex predilection, who were divided into two groups. The first group (20 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (20 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. The samples were processed for the detection of biofilms by scanning electron microscopy. The biofilm formation was graded according to extension. Biofilm formation was detected on all samples for group 1. Adenoids removed from patients with otitis media with effusion had higher-grade biofilm formation than the other group (P 0.0001). No correlation was found between adenoid size and biofilm formation. In pediatric population, adenoid surface biofilm formation may be involved in the pathogenesis otitis media with effusion.

    The objective of this study was to describe the clinical course and response to treatment of five patients who developed loculated pleural effusions as complications of pulmonary thromboembolism (PTE). The clinical charts of five patients who had loculated pleural effusions in the course of their PTE were reviewed, with special attention paid to the duration of symptoms before diagnosis, the pleural fluid analysis findings, and the response of the loculations to anticoagulant therapy. In a tertiary care academic medical center, the five patients described in the present study had multiple locules of pleural fluid seen on chest radiographs and thoracic CT scans. In all cases, the diagnosis of PTE had been delayed for at least 2 weeks after symptoms developed. The loculated pleural fluid had led to the mistaken diagnosis of empyema in three cases. The pleural fluid in all cases was exudative, with a predominance of lymphocytes. With anticoagulant therapy, the loculations largely disappeared within the first few days of therapy. Although most pleural effusions secondary to PTE are relatively small and free-flowing, this study demonstrates that PTE can lead to loculated pleural effusions. The loculations occurred in patients who had been symptomatic from their PTE for > 2 weeks. In each instance, the pleural fluid was a lymphocytic exudate. The effusions rapidly resolved with the institution of anticoagulant therapy. PTE should be included in the differential diagnosis of a loculated pleural effusion, particularly if the pleural fluid contains predominantly lymphocytes.

    Background. We performed prospective validation of the cancer ratio (serum LDH : pleural ADA ratio), previously reported as predictive of malignant effusion retrospectively, and assessed the effect of combining it with “pleural lymphocyte count” in diagnosing malignant pleural effusion (MPE). Methods. Prospective cohort study of patients hospitalized with lymphocyte predominant exudative pleural effusion in 2015. Results. 118 patients, 84 (71.2%) having MPE and 34 (28.8%) having tuberculous pleural effusion (TPE), were analysed. In multivariate logistic regression analysis, cancer ratio, serum LDH : pleural fluid lymphocyte count ratio, and “cancer ratio plus” (ratio of cancer ratio and pleural fluid lymphocyte count) correlated positively with MPE. The sensitivity and specificity of cancer ratio, ratio of serum LDH : pleural fluid lymphocyte count, and “cancer ratio plus” were 0.95 (95% CI 0.87–0.98) and 0.85 (95% CI 0.68–0.94), 0.63 (95% CI 0.51–0.73) and 0.85 (95% CI 0.68–0.94), and 97.6 (95% CI 0.90–0.99) and 94.1 (95% CI 0.78–0.98) at the cut-off level of >20, >800, and >30, respectively. Conclusion. Without incurring any additional cost, or requiring additional test, effort, or time, cancer ratio maintained and “cancer ratio plus” improved the specificity of cancer ratio in identifying MPE in the prospective cohort.

    Kelud volcano, (Indonesia) has in recent years demonstrated the classical dichotomy of eruptive styles, with an effusive dome eruption in 2007-08 and an explosive Plinian eruption in 2014, causing widespread ash fall and the evacuation of 100,000 people. This study compares both the deep (magma reservoir) and shallow (conduit feeder system) magmatic processes that occurred before both eruptions, using a combination of petrography as well as analytical and experimental petrology. The first results from this study show that despite their significant differences in eruptive style, these eruption products had identical magma compositions, comprising of basaltic andesite. Furthermore, the phenocryst assemblage and mineral compositions of the explosive and effusive products are also similar, pointing towards equivalent pre-eruptive storage conditions. The key difference lies within the microlite populations and matrix glass chemistry. These suggest that the eruptive style is determined by the ascent history, with different P(H2O)-T-t paths leading to either effusive or explosive behavior. Interestingly, some plagioclase phenocrysts preserve progressive capture of small melt inclusions during different stages of crystal growth. Raman spectroscopic analysis of these small melt inclusions from crystal core to rim, provides a unique view of magmatic water contents during magma reservoir evolution. We speculate that water content variations (~0.6 - 2.3%) may exist due to a complex interplay between the fractionating basaltic andesite and fresh mafic injections. This study will also show the preliminary results from the first phase experiments done on Kelud volcanics, constraining the magmatic storage conditions preceding both the 2014 explosive and 2007 effusive eruptions.

    To compare the efficacy of two treatment regimens among Helicobacter pylori stool antigen positive children suffering from resistant otitis media with effusion. The study comprised 258 children with bilateral otitis media with effusion; 134 were positive for H pylori stool antigen, and were equally and randomly allocated to the control group or study group. The control group received standard otitis media with effusion therapy (amoxicillin and clavulanate), while the study group received standard H pylori triple therapy (clarithromycin, metronidazole and lansoprazole). In the control group, there was a marked clinical response to treatment in 33 of the 67 children (49.3 per cent). In the study group, there was a marked response in a significantly higher number of children (46 out of 67, 68.7 per cent). The 124 H pylori stool antigen negative children not included in the 2 aforementioned groups received amoxicillin and clavulanate, and a marked response in symptoms was evident in 98 of these children (79 per cent). H pylori infection may lead to resistance to traditional otitis media with effusion treatment in some cases. H pylori eradication is associated with a high cure rate.

    Kawasaki disease is an acute, febrile, self-limiting, inflammatory systemic vasculitis seen in early childhood, most commonly in those below 5 years of age. In Kawasaki disease, the coronary arteries are most commonly affected, which may lead to asymptomatic coronary artery ectasia or formation of an aneurysm. Paroxysmal supraventricular tachycardia(PSVT) is a severe and rare cardiovascular complication of Kawasaki disease. A case of Kawasaki disease presenting with unusual findings, including subdural effusion and PSVT is reported. This is a 4-month-10-day-old boy presents with anterior fontanelle bulging and moderate bilateral subdural effusion at the acute stage of Kawasaki disease and PSVT at the subacute stage of Kawasaki disease. The subdural effusion was resolution after intravenous immunoglobulin(IVIG) administration. And the PSVT was subsided after administered 3 doses of adenosine, 1 dose of amiodarone loading and Propranolol twice per day use. At 1-year follow-up has made a complete recovery with no arrhythmia episodes, developmental effects or abnormal neurologic findings. Subdural effusion in the acute stage of Kawasaki disease may be an inflammatory response. It may resolves spontaneously after anti-inflammatory treatment such as IVIG infusion. PSVT is a severe cardiovascular complication of Kawasaki disease. In those who taking aspirin, we need to carefully observe the heart rhythm and PSVT side effects, especially in the first month.

    Lymphangioleiomyomatosis (LAM) is a rare, slowly progressive lethal lung disease primary afflicting young women. LAM is characterized by proliferation of abnormal smooth muscle cells that target the lungs, causing cystic destruction and eventual respiratory failure leading to death. Recent ten year mortality due to end stage LAM has been reported to be approximately 10%-20%, but may vary. The decline in lung function in LAM is gradual, occurring at a rate of about 3% to 15% per year but can vary from patient to patient. But recently therapy with mammalian target of rapamycin (mTOR) inhibitors such as sirolimus has shown promising results in the stabilization of lung function and reduction of chylous effusions in LAM. Lung transplantation is a viable option for patients who continue to have decline in lung function despite mTOR therapy. Unique issues that may occur post-transplant in a recipient with LAM include development of chylous effusion and a risk of recurrence. We describe a case of LAM recurrence in a bilateral lung transplant recipient who developed histological findings of LAM nine years after transplantation. PMID:27011924

    The effects of pneumothorax or pleural effusion on respiratory function as measured by the commonly applied tests were investigated by studying 13 patients (six with pneumothorax, seven with effusion) with and, as far as possible, without air or fluid in the pleural cavity. Measurements included spirometric volumes, carbon monoxide transfer factor (TLCO), and KCO by the single breath method, maximum expiratory flow-volume curves, and subdivisions of lung volume estimated by both inert gas dilution and body plethysmography. In patients with pneumothorax "pleural volume" was estimated as the difference between lung volumes measured by dilution and thoracic gas volume measured by plethysmography. In patients with effusion the change in "pleural volume" was equated with the volume of fluid subsequently aspirated. "Total thoracic capacity" (TTC) was estimated by adding total lung capacity (TLC) measured by dilution and "pleural volume." Both effusion and pneumothorax produced a restrictive ventilatory defect with reductions of vital capacity, functional residual capacity, and TLC. In the patients with effusion TTC fell after aspiration, suggesting that the pleural fluid produced relative expansion of the chest wall as well as compression of the lung. In patients with pneumothorax, however, there was no difference in TTC with and without air in the pleural space. In the presence of pleural air or fluid there was a slight decrease in TLCO and increase in KCO, with a small but significant increase in the rate of lung emptying during forced expiration.

    Malignant pericardial effusion is usually treated only when signs of cardiac tamponade develop. Several methods of treatment have been reported with an overall response rate of approximately 75%. Since our initial study using intrapericardial 32P-colloid instillation as a treatment modality for pericardial effusion demonstrated a significant higher response rate, this study was conducted to further evaluate the efficacy of intrapericardial 32P-colloid in terms of response rates and duration of remissions. Intrapericardial instillation of 185–370 MBq (5–10 mCi) 32P-colloid in 36 patients with malignant pericardial effusion resulted in a complete remission rate of 94.5% (34 patients) whereas two patients did not respond to treatment due to a foudroyant formation of pericardial fluid. The median duration time was 8 months. No side-effects were observed. These results suggest that intrapericardial instillation of 32P-colloid is a simple, reliable and safe treatment strategy for patients with malignant pericardial effusions. Therefore, since further evidence is provided that 32P-colloid is significantly more effective than external radiation or non-radioactive sclerosing agents, this treatment modality should be considered for the management of malignant pericardial effusion. © 1999 Cancer Research Campaign PMID:10471044

    To describe the technique and our experience in percutaneous creation of a pericardial window in patients with recurrent pericardial effusion. Eleven consecutive patients (9 men, 2 women; mean age 61 years, range 37-79 years) with recurrent pericardial effusion were treated from December 1994 to October 2000. Malignant effusion was the cause of cardiac tamponade in nine patients. Puncture of the pericardial space was performed under ultrasound and fluoroscopic guidance. Once a guidewire was safely positioned in the pericardial cavity and the wall of the pericardium was identified, the pericardial keyhole was dilated with an 18 mm balloon catheter. A temporary (1-3 day) 8 Fr pigtail catheter was inserted in order to stabilize the tract and aspirate the fluid. The aim of creating a pericardial window was achieved in all 11 patients. There were three recurrences (27%) of pericardial effusion and three early deaths (27%) due to progression of the underlying disease, which occurred within 30 days following the procedure. Follow-up ranged from 6 days to 382 days, mean 147 days. Percutaneous creation of a pericardial window can be a safe therapeutic alternative for patients with symptomatic pericardial effusion, particularly if this has a malignant etiology.

    A 27-year-old woman developed bilateral acute angle closure glaucoma (AACG) and transient myopia after taking oseltamivir for four days. On the fourth day, she received systemic and topical intraocular pressure (IOP)-lowering agents, and IOP decreased in both eyes. However, her visual acuity was unchanged. A myopic shift of -5.25 D OD and -5.0 D OS was estimated to have occurred in the acute phase. A-scan ultrasonography and Pentacam showed markedly shallow anterior chambers and increased lens thickness. Ultrasound biomicroscopy revealed an annular ciliochoroidal effusion with forward displacement of the lens-iris diaphragm. Ciliochoroidal effusion and transient myopia were resolved after discontinuation of oseltamivir. PMID:23571265

    The clinical relevance of pleural effusions in lung cancer has seldom been approached systematically. The aim of this study was to determine the prevalence, causes and natural history of lung cancer-associated pleural effusions, as well as their influence on survival. Retrospective review of clinical records and imaging of 556 consecutive patients with a newly diagnosed lung cancer over a 4-year period at our institution. Lung cancer comprised 490 non-small cell and 66 small cell types. About 40% of patients with lung cancer developed pleural effusions at some time during the course of their disease. In half the patients, the effusions were too small to be tapped. These effusions did not progress to require a pleural intervention. Patients with minimal effusions had a worse prognosis compared to patients without pleural effusions (median survival of 7.49 vs 12.65 months, P < 0.001). Less than 20% of the 113 patients subjected to a diagnostic thoracentesis had benign causes for their effusions. Palliative pleural procedures (like therapeutic thoracenteses, pleurodesis or tunnelled pleural catheters) were conducted in 79 (84%) of the 94 malignant effusions. An effusion's size equal to or greater than half of the hemithorax was a strong predictor of the need for a palliative procedure. Overall survival of patients with malignant effusions was 5.49 months. Malignant pleural effusions are a poor prognostic factor in the setting of lung cancer, which includes minimal effusions not amenable to tapping. © 2015 Asian Pacific Society of Respirology.

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    A 52-year-old Mexican man presented with asymptomatic, bilaterally symmetrical lipid infiltrates of the cornea and adjacent limbus. No evidence of previous ocular disease or systemic disorder of lipid metabolism could be detected. Penetrating keratoplasty of the right eye was required. The cornea was rigid and thick, with posterior bulging into the anterior chamber. Light microscopy revealed deep corneal lipid granules, foamy histiocytes, vascularisation, and chronic non-granulomatous inflammation. Transmission electron microscopy showed extracellular lipid spaces and numerous intracytoplasmic lipid vacuoles in histiocytes, keratocytes, conjunctival epithelium, and the endothelium of blood vessels in the corneal stroma and adjacent limbal conjunctiva. Histochemical analysis revealed the presence of neutral fats, free fatty acids, cholesterol, and phospholipids. Images PMID:3395592

    The authors report four patients with a syndrome of painless bilateral isolated phrenic neuropathy. Electrophysiologic testing demonstrated active denervation restricted to the diaphragm. Long-term recovery was poor. The authors conclude that bilateral isolated phrenic neuropathy is a cause of painless diaphragmatic paralysis distinguishable from immune brachial plexus neuropathy and other neuromuscular disorders with similar clinical presentation.

    The trabectome is a novel form of ab interno trabeculectomy that ablates and remove the trabecular meshwork and the inner wall of Schlemm's canal and subsequently expose the natural drainage pathway (the collector channels) to aqueous humor. Complications associated with the trabectome are few and among them is transient hypotony. We report a case of a prolonged ciliochoroidal effusion with hypotony after ab interno trabeculectomy using the trabectome with cyclodialysis cleft detected by 80 MHz ultrasound biomicroscopy in a previously neither nonoperated nor traumatized eye. Transient hypotony has been reported after the trabectome surgery. Very few cases were associated with inadvertent intraoperative cyclodialysis, but there are no cases of prolonged hypotony with ciliochoroidal effusion with cyclodialysis. In our case, associated transient intraoperative and postoperative hypotony with a history of chronically high pressure along with the possible contribution of low-grade postoperative inflammation may have precipitated the ciliochoroidal effusion with prolonged hypotony associated with cyclodialysis.

    Purpose: To report a case of choroidal effusion probably caused by angiotensin receptor II blocker. Case Report: A 52-year-old man with aplastic anemia and high blood pressure who developed unilateral acute angle closure glaucoma after receiving oral cyclosporine and angiotensin II receptor blocker (losartan). Ophthalmic examination revealed visual acuity of 20/30 in the left eye, mild mydriasis, iris bombe, no anterior chamber reaction, mild conjunctival hyperemia, and the intraocular pressure of 30 mmHg. After laser YAG iridotomy, funduscopy was performed showing a choroidal circumscribed lesion at the inferotemporal quadrant. Diagnostic tests ruled out any inflammatory or malignancy process, and the choroidal lesion spontaneously disappeared. After 20 months of follow-up, patient's ocular remained stable. Conclusion: This is the third case of choroidal effusion associated with angiotensin II receptor blockers. Since idiosyncratic ciliochoroidal effusion is a diagnosis of exclusion, it is mandatory to rule out more frequent causes, such as inflammatory or malignant processes. PMID:28299016

    The pathological accumulation of serous fluids in the pleural, peritoneal and pericardial space occurs in a variety of conditions. Since patient management depends on right and timely diagnosis, biochemical analysis of extravascular body fluids is considered a valuable tool in the patient management process. The biochemical evaluation of serous fluids includes the determination of gross appearance, differentiation of transudative from exudative effusions and additional specific biochemical testing to assess the effusion etiology. This article summarized data from the most relevant literature concerning practice with special emphasis on usefulness of biochemical tests used for the investigation of pleural, peritoneal and pericardial effusions. Additionally, preanalytical issues concerning serous fluid analysis were addressed and recommendations concerning acceptable analytical practice in serous fluid analysis were presented.

To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 18 recommendations developed emphasize diagnostic accuracy, identification of children who are most susceptible to developmental sequelae from otitis media with effusion, and education of clinicians and patients regarding the favorable natural history of most otitis media with effusion and the lack of efficacy for medical therapy (eg, steroids, antihistamines, decongestants). An updated guideline is needed due to new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group.

    Thirty-eight children with hip pain of acute onset were studied by bone scintigraphy. Nine patients had diminished radiotracer deposition involving the entire proximal femoral ossification center. This could be related to infarction or compression of blood supply by a tense joint effusion. Eight of these patients had joint aspiration confirming the presence of an effusion. Five patients had follow-up studies after aspiration, and femoral-head uptake reverted to normal in all but one which subsequently proved to be infarcted. A photopenic zone was seen on blood pool images in 10 patients, many of whom were also aspirated of fluid. Bone scintigraphy is useful in the diagnosis of joint effusions and can give information as to the state of perfusion of the femoral head. Follow-up studies after aspiration can differentiate infarction from reversible ischemia.

    Mycobacterium fortuitum is a non-tuberculous mycobacterium that can cause pneumonia, abscess and empyema in subjects with predisposing lung diseases. However, pleurisy with effusion is rare. Herein, we report the case of a 74-year-old immunocompetent female patient without apparent risk factors, who suffered haemorrhagic pleural effusion as the main clinical manifestation. Pleural nodules were detected by computed tomography scan, and microbiological analysis revealed M. fortuitum in the absence of other pathogens. The patient was treated with ceftriaxone and ciprofloxacin, and full recovery ensued in 4 weeks. To our knowledge, this is the first reported case of haemorrhagic pleural effusion in an immunocompetent patient without underlying diseases. Although non-tuberculous mycobacterial infections are rarely accompanied by pleural involvement, M. fortuitum should be considered in such cases, especially when microbiology fails to detect the usual pathogens, and when the clinical picture is unclear.

    In this work, we show a particular setup, which is based on the conventional photoacoustic cell, to measure thermal effusivity of human skin in-vivo and in-situ. We measure the changes of thermal effusivity due to the absorption of sunscreen into the skin and these values are compared with those from an adjacent sample of clean skin. This experiment was performed on a volunteer's forearm and stainless steel as the thermally thin absorption surface. The values for this parameter are in good agreement with those reported in the literature. Besides the measurements described above, with the same setup we got the thermal effusivity of the sunscreen itself as a reference parameter. R

    In this paper, we introduce a high efficient and practical disparity estimation using hierarchical bilateral filtering for real-time view synthesis. The proposed method is based on hierarchical stereo matching with hardware-efficient bilateral filtering. Hardware-efficient bilateral filtering is different from the exact bilateral filter. The purpose of the method is to design an edge-preserving filter that can be efficiently parallelized on hardware. The proposed hierarchical bilateral filtering based disparity estimation is essentially a coarse-to-fine use of stereo matching with bilateral filtering. It works as follows: firstly, the hierarchical image pyramid are constructed; the multi-scale algorithm then starts by applying a local stereo matching to the downsampled images at the coarsest level of the hierarchy. After the local stereo matching, the estimated disparity map is refined with the bilateral filtering. And then the refined disparity map will be adaptively upsampled to the next finer level. The upsampled disparity map used as a prior of the corresponding local stereo matching at the next level, and filtered and so on. The method we propose is essentially a combination of hierarchical stereo matching and hardware-efficient bilateral filtering. As a result, visual comparison using real-world stereoscopic video clips shows that the method gives better results than one of state-of-art methods in terms of robustness and computation time.

    A prospective study of outcome after inguinal hernia repair in patients undergoing simultaneous repair of bilateral hernias (n = 31), sequential repair of bilateral hernias (n = 5), and unilateral hernia repair (n = 75) is reported. There were no differences in wound complications, post-operative respiratory complications, or other adverse effects in the three groups. Operating time was similar in the unilateral and bilateral simultaneous repairs (median 55 min), but was longer (100 min) for the combination of two sequential repairs. Hospital stay was shortest for patients undergoing unilateral repair (2 days) but was less with bilateral simultaneous repair (4 days) than after two sequential repairs (total of 6 days). There were 12 (11%) wound complications of which five (5%) were infections. There was no difference in complication rate between unilateral and bilateral hernia repair. Postoperative recovery was assessed prospectively and was recorded at 1 month. There was no difference between unilateral and bilateral simultaneous repairs in the number of days before the patient was able to climb stairs easily, drive a car or return to work. The duration of the requirement for analgesia was similar in each group. We conclude that bilateral simultaneous hernia repair can be carried out with no greater morbidity than a unilateral repair, and the return to normal activity is as rapid. Bilateral hernias should be repaired simultaneously rather than sequentially. PMID:2221764

    To evaluate the feasibility of video-assisted thoracoscopy (VAT) for staging advanced ovarian cancer, to measure the performance of preoperative computed tomography (CT) for diagnosing pleural metastases, to assess the correlation between pleural and abdominal involvement, and to measure the impact of VAT on patient management. We retrospectively evaluated 16 VAT procedures in 15 patients with advanced ovarian malignancies and pleural effusions. The reason for VAT was either to evaluate unilateral or bilateral pleural effusions (n = 15) or to evaluate pleural metastases after neoadjuvant chemotherapy (n = 1). Preoperative CT was performed routinely, and findings were compared with those of VAT. The rates of involvement of the hepatic pedicle, mesentery, and right side of the diaphragm were compared with the rate of pleural involvement. The right side of the chest was examined 12 times; and the left side, 4 times. There were no complications; 1 procedure was stopped because of ventilatory intolerance. Video-assisted thoracoscopy identified metastases smaller than 1 cm in 5 patients and larger than 1 cm in 2 additional patients; there was no evidence of pleural involvement in 6 patients. Computed tomography had 14% sensitivity and 25% specificity for pleural status determination, using VAT biopsy as the reference standard. Pleural involvement did not correlate with involvement of the hepatic pedicle, mesentery, or right side of the diaphragm. Video-assisted thoracoscopy performs better than CT for evaluating pleural involvement in ovarian cancer. Video-assisted thoracoscopy supplies accurate data on thoracic involvement, which does not seem predictable from the peritoneal involvement. Video-assisted thoracoscopy may impact patient management.

    Background This case report documents the affliction of the lymph vessels as a phenotypic feature of neurofibromatosis-1 (NF-1). Methodology Routine transthoracic echocardiography, computed tomography scan of the thorax, magnetic resonance angiography of the renal arteries, and conventional digital subtraction angiography were applied. Comprehensive NF-1 mutation analysis was carried out by fluorescence in situ hybridization analysis, long-range reverse transcriptase polymerase chain reaction, and multiple-ligation probe assay. All other investigations were performed using routine, well-established techniques. Results The subject is a 34-year-old, half-Chinese male; NF-1 was suspected at age 15 years for the first time. His medical history included preterm birth, mild facial dysmorphism, “café au lait” spots, subcutaneous and paravertebral fibromas, multifocal tachycardia, atrial fibrillation, and heart failure in early infancy. Noncalcified bone fibromas in the femur and tibia were detected at age 8 years. Surgical right leg lengthening was carried out at age 11 years. Bilateral renal artery stenosis, stenosis and aneurysm of the superior mesenteric artery, and an infrarenal aortic stenosis were detected at age 15 years. Leg edema and ectasia of the basilar artery were diagnosed at age 18 years. After an episode with an erysipela at age 34 years, he developed pericardial and pleural effusion during a 4-month period. Stenosis of the left subclavian vein at the level of thoracic duct insertion was detected. After repeated pleural punctures, pleural effusion was interpreted as chylothorax. Reduction of lymph fluid production by diet and injection of talcum into the pleural cavity had a long-term beneficial effect on the chylothorax. Leg edema and chylothorax were attributed to affliction of the lymph vessels by the NF-1. Discussion Lymphangiopathy resulting in impaired lymph fluid flow and sequestration of lymph fluid into the pleural sinus and the legs may be a

    Forty-seven patients with a known history of thoracic trauma or clinical suspicion of pneumothorax were selected for thoracic imaging. The patient population was composed of 42 dogs and five cats. Standard vertical beam (VB) left and right lateral and ventrodorsal/dorsoventral (VD/DV) projections were obtained for each patient, and at least one horizontal beam (HB) projection (VD projection made in lateral recumbency). A total of 240 images were reviewed. Subjective assessment for the presence and degree of pneumothorax and pleural effusion was made more confidently with HB projections. Pneumothorax was identified in at least one projection in 26 patients (26 dogs) and pleural effusion in 21 patients (19 dogs and two cats). Pneumothorax and pleural effusion were present concurrently in 17 dogs. Pneumothorax and pleural effusion were graded for each image as absent, mild, moderate, or severe. Right (P < 0.001) and left (P < 0.05) lateral HB VD projections and the standard VB left lateral projection (P < 0.05) were significantly more likely to detect and grade pneumothorax severely than the VB VD/DV views. The right lateral HB projection had the highest rate of detection and gradation of severity for pneumothorax compared with other views. VD/DV projections had the lowest sensitivity for detection of the pneumothorax and gradation of severity for pneumothorax and pleural effusion. No significant difference in diagnosis (P = 0.9149) and grade (P = 0.7757) of pleural effusion were seen between views, although the left lateral HB had both the highest rate of detection and grade of severity.

    In this study, the effects of surface-active substances, pH and salt on the effusion of HOCs from droplets were investigated. An HOCs-effusion reactor was established for experiments. N-octane was used for the HOCs and Sodium Dodecyl Sulfate (SDS) was selected as the surface-active substance. A correction factor to mass exchange constant, defined as the deviation of exchange constant of n-octane in fog phase from that in planar aqueous phase was used to quantify the effects of surface-active substance, pH, and salt concentration on the effusion rate of HOCs from fog droplets by a modified double-layer diffusion model. The results showed that surface-active substances, SDS cab decrease the effusion rate of n-octane from fog droplets by about 40%--62% and the values of were in the range of 0.382 to 0.609. The salt, sodium chloride, at the concentration of 1.00 {times} 10{sup {minus}3} [M] can further decrease the mass transfer rate of n-octane from fog droplets because the values changed from 0.590 to 0.368, so that the effusion rate was further decrease by salt. When pH values were between 5.60 and 2.00, values varied from 0.609 to 0.367 at SDS concentration of 1.00 x 10{sup 3}[M]. This indicated that the effusion rate of HOCs from fog droplets decreased with decreasing pH value.

    To know the behavior of cellular components of pleural fluid can help focus the differential diagnosis of a pleural effusion. Our objective was to assess their composition in different types of pleural effusions and assess whether it provides relevant clinical information. Observational, cross-sectional and retrospective study in which the cellular components of pleural effusions of different etiology were analyzed. Pleural effusions were classified as neutrophilic, lymphocytic (≥50% of each one of them), eosinophilic (≥10%) or mesothelial (>5%) and were grouped into six diagnostic categories RESULTS: 1.467 patients were studied (354 heart failure; 59 other transudates; 349 paraneumonic; 133 tuberculous; 397 malignant and 175 other exudates). The predominance cell was lymphocytic in heart failure (44,4%), uncomplicated parapneumonic (29,2%), tuberculosis (88%) and malignant (49,6%); neutrophilic in parapneumonic (57%) and malignant (9,6%); eosinophilic in malignant (6,3%) and mesotelial in tuberculosis (12%). The most frequent etiologies with lymphocyte count ≥80% were tuberculosis (35,1%) and malignant (23,3%). Parameters with higher discriminating accuracy were: leukocytes (transudates: AUC 0,835) and percentage of neutrophils (empyemas: AUC 0,906 and complicated parapneumonic+empyemas: AUC 0,907). Nucleated cell counts will help focus the etiology of pleural effusions, since each etiology often have a characteristic cell predominance. The percentage of nucleated cells in pleural fluid not ruled out tuberculosis if there is a high count of mesothelial cells, nor a parapneumonic effusion with lymphocytic predominance, or malignancy with ≥80% lymphocytes.

    The purpose of this study was to assess the utility of CT in characterizing pleural effusions on the basis of attenuation values and CT appearance. We retrospectively analyzed 100 pleural effusions in patients who underwent chest CT and diagnostic thoracentesis within 48 hours of each other. On the basis of Light's criteria, effusions were classified as exudates or transudates using laboratory biochemistry markers. The mean value in Hounsfield units of an effusion was determined using a region of interest on the three slices with the greatest quantity of fluid. All CT scans also were reviewed for the presence of additional pleural features such as fluid loculation, pleural thickening, and pleural nodules. Twenty-two of the 100 pleural effusions were transudates and 78 were exudates. The mean attenuation of the exudates (7.2 HU; [SD] 9.4 HU; range, 21-28 HU) was not significantly lower than the mean attenuation of the transudates (10.1 HU; 6.9 HU; range, 0.3-32 HU), (p = 0.24). None of the additional CT features accurately differentiated exudates from transudates (p > 0.1). Fluid loculation was found in 58% of exudates and in 36% of transudates. Pleural thickening was found in 59% of exudates and in 36% of transudates. The clinical use of CT attenuation values to characterize pleural fluid is not accurate. Although fluid loculation, pleural thickness, and pleural nodules were more commonly found in patients with exudative effusions, the presence of these features does not accurately differentiate between exudates and transudates.

    Introduction The purpose of the present study was to determine the prevalence of cystic lesions and cyst-like bursitides in subjects with frequent knee pain and to assess their relation to radiographic osteoarthritis (OA) severity; to describe bilaterality and size fluctuation of the lesions over 6 months; and to assess relations between the prevalence of synovium-lined lesions communicating with the joint capsule and severity of magnetic resonance imaging (MRI)-detected effusion and synovitis. Methods One hundred and sixty-three subjects (total 319 knees) aged 35 to 65 with chronic, frequent knee pain were included. Imaging with 3 Tesla MRI was performed at baseline and 6-month follow-up with the same protocols as those used in the Osteoarthritis Initiative. Severity of radiographic OA was assessed using the Kellgren-Lawrence grade (0 to 4). Severity of effusion and synovitis was graded 0 to 3 based on the Whole Organ Magnetic Resonance Imaging Score system. The associations of cysts and cyst-like bursitides and severity of radiographic OA, MRI-detected effusion and synovitis were analyzed using logistic regression controlling for clustering by person. The Wilcoxon signed-rank test was used to determine whether there was a significant change in the size of lesions between baseline and follow-up. Results At least one lesion (any type) was present in 222 (70%) knees. The most prevalent lesions were popliteal cysts (40%, 128/319), followed by subgastrocnemius bursitis (15%, 49/319) and proximal tibiofibular joint cysts (8%, 26/319). Bilateral lesions were seen in 49% of the subjects. Only popliteal cysts and subgastrocnemius bursitis showed a significant change in size (P < 0.001). No trend was observed between prevalence of any of the cyst-like lesions analyzed and the increasing radiographic OA severity. Increasing prevalence of subgastrocnemius bursitis was associated with increasing severity of effusion (P = 0.0072) and synovitis (P = 0.0033). Conclusions None of

    To evaluate the best time to perform thoracoscopy for the treatment of complicated parapneumonic pleural effusion in the fibrinopurulent phase in patients ≤ 14 years of age, regarding the postoperative evolution and occurrence of complications. This was a retrospective comparative study involving patients with parapneumonic pleural effusion presenting with septations or loculations on chest ultrasound who underwent thoracoscopy between January of 2000 and January of 2013. The patients were divided into two groups: early thoracoscopy (ET), performed by day 5 of hospitalization; and late thoracoscopy (LT), performed after day 5 of hospitalization. We included 60 patients, 30 in each group. The mean age was 3.4 years; 28 patients (46.7%) were male; and 47 (78.3%) underwent primary thoracoscopy (no previous simple drainage). The two groups were similar regarding gender, age, weight, and type of thoracoscopy (p > 0.05 for all). There was a significant difference between the ET and the LT groups regarding the length of the hospital stay (14.5 days vs. 21.7 days; p < 0.001). There were also significant differences between the groups regarding the duration of fever in days; the total number of days from admission to the initiation of drainage; and the total number of days with the drain in place. Eight patients (13.6%) had at least one post-thoracoscopy complication, there being no difference between the groups. There were no deaths. Performing ET by day 5 of hospitalization was associated with shorter hospital stays, shorter duration of drainage, and shorter duration of fever, although not with a higher frequency of complications, requiring ICU admission, or requiring blood transfusion.

    To assess a new technique for the detection of free pleural fluid. 118 consecutive inpatients with radiologic evidence of free pleural fluid and a control group of 175 randomly selected inpatients were examined over a three-year period in a prospective blind study by auscultatory percussion (AP) for evidence of pleural effusion. The cutoff in the percussion note by AP is strikingly loud and sharp at the fluid level and allows precise delineation of even minimal amounts of pleural fluid. The fluid level was measured in reference to the last rib. The criterion for detection of pleural effusion by AP was a demonstrable horizontal fluid level at the sound cutoff across the posterior hemithorax above the last rib that shifted with lateral tilt. A general medical and surgical university-affiliated teaching Veterans Affairs hospital. All inpatients were eligible. Ready availability of examiners was essential. Rotating third- and fourth-year medical students, residents, and senior staff members participated. None. 113 of the 118 patients with radiologic evidence of pleural effusion had a distinct horizontal fluid level above the last rib that shifted with lateral tilt (sensitivity = 95.8%). None of the 175 control patients examined at random showed evidence of pleural effusion by AP examination, which was confirmed by chest radiography (specificity = 100%). Nine of the 175 patients without radiologic evidence of pleural effusion had elevated diaphragms that simulated a fluid level in the examination by AP. Each of the nine patients, however, had no shift in the level with lateral tilt. Subpulmonic effusions were readily displaced and identified by this method of AP. Examination by AP is highly sensitive and specific for the detection of free pleural fluid, even in the presence of obesity, thickened pleura, lung masses, pneumonia, and associated lung disease. The examination correlates closely with standard and lateral decubitus chest radiography. Pleural effusion

    The treatment of chronic recurrent pleural effusions continues to evolve with the recent emergence of tunneled indwelling pleural catheters (IPCs). Talc pleurodesis has been the standard of care for treatment of recurrent pleural effusions, but IPCs have gained more favor in recent years. IPCs offer several advantages, including a less invasive procedure, short postprocedure hospital stay, and greater patient control in the management of symptoms. Further randomized controlled studies are needed to more clearly differentiate which patients are better served by an IPC rather than traditional pleurodesis as their initial intervention.

    The computed tomographic scans of 38 patients with proven subphrenic abscesses and 28 patients with proven pleural effusions were reviewed without knowledge of the final diagnosis. In 26% of cases the hemidiaphragm could be identified directly as a stripe, while in 71% of cases only the hemidiaphragmatic contour could be seen. In 3% of cases the hemidiaphragm position was indeterminate because insufficient scans of the chest or abdomen were obtained. In the cases where the hemidiaphragm position could be established, the computed tomographic diagnosis was correct in 100% of subphrenic abscesses and in 96% of pleural effusions. Methods of identifying the hemidiaphragm on computed tomography and the possible pitfalls are discussed.

    Although during the last few years there have been several important changes in the diagnostic or therapeutic methods, pleural effusion is still one of the diseases that the respiratory specialist have to evaluate frequently. The aim of this paper is to update the knowledge about pleural effusions, rather than to review the causes of pleural diseases exhaustively. These recommendations have a longer extension for the subjects with a direct clinical usefulness, but a slight update of other pleural diseases has been also included. Among the main scientific advantages are included the thoracic ultrasonography, the intrapleural fibrinolytics, the pleurodesis agents, or the new pleural drainages techniques.

    Introduction The use of patients’ own cancer cells for in vitro selection of the most promising treatment is an attractive concept in personalized medicine. Human carcinoma cells from malignant pleural effusions (MPEs) are suited for this purpose since they have already adapted to the liquid environment in the patient and do not depend on a stromal cell compartment. Aim of this study was to develop a systematic approach for the in-vitro culture of MPEs to analyze the effect of chemotherapeutic as well as targeted drugs. Methods MPEs from patients with solid tumors were selected for this study. After morphological and molecular characterization, they were cultured in medium supplemented with patient-derived sterile-filtered effusion supernatant. Growth characteristics were monitored in real-time using the xCELLigence system. MPEs were treated with a targeted therapeutic (erlotinib) according to the mutational status or chemotherapeutics based on the recommendation of the oncologists. Results We have established a robust system for the ex-vivo culture of MPEs and the application of drug tests in-vitro. The use of an antibody based magnetic cell separation system for epithelial cells before culture allowed treatment of effusions with only moderate tumor cell proportion. Experiments using drugs and drug-combinations revealed dose-dependent and specific growth inhibitory effects of targeted drugs. Conclusions We developed a new approach for the ex-vivo culture of MPEs and the application of drug tests in-vitro using real-time measuring of cell growth, which precisely reproduced the effect of clinically established treatments by standard chemotherapy and targeted drugs. This sets the stage for future studies testing agents against specific targets from genomic profiling of metastatic tumor cells and multiple drug-combinations in a personalized manner. PMID:27548442

    Despite similar mechanisms driving pleural fluid accumulation, the causes of pleural effusions in children differ significantly from that of adults. When a pleural effusion re-occurs in an adult, literature recommends early thoracentesis, and consideration for pleuroscopy with biopsy to guide the diagnostic evaluation. In children, there is a paucity of literature for guiding management of recurrent exudative pleural effusion. We present an unusual pediatric case of uremic pleuritis with recurrent pericardial and exudative pleural effusions. © 2017 Wiley Periodicals, Inc.

    Untargeted mass spectrometry-based metabolomic profiling is a powerful analytical method used for broad-spectrum identification and quantification of metabolites in biofluids in human health and disease states. In this study, we exploit metabolomic profiling for cancer biomarker discovery for diagnosis of malignant pleural effusions. We envisage the result will be clinically useful since currently there are no cancer biomarkers that are accurate enough for the diagnosis of malignant pleural effusions. Metabolomes of 32 malignant pleural effusions from lung cancer patients and 18 benign effusions from patients with pulmonary tuberculosis were analyzed using reversed-phase liquid chromatography tandem mass spectrometry (LC-MS/MS) using AB SCIEX TripleTOF 5600. MS spectra were analyzed using XCMS, PeakView, and LipidView. Metabolome-Wide Association Study (MWAS) was performed by Receiver Operating Characteristic Curve Explorer and Tester (ROCCET). Insignificant markers were filtered out using a metabolome-wide significance level (MWSL) with p-value < 2 × 10(-5) for t test. Only compounds in Human Metabolome Database (HMDB) will be used as cancer biomarkers. ROCCET analysis of ESI positive and negative MS spectra revealed free fatty acid (FFA) 18:1 (oleic acid) had the largest area-under-ROC of 0.96 (95% CI = 0.87-1.00) in malignant pleural effusions. Using a ratio of FFA 18:1-to-ceramide (d18:1/16:0), the area-under-ROC was further increased to 0.99 (95% CI = 0.91-1.00) with sensitivity 93.8% and specificity 100.0%. Using untargeted metabolomic profiling, the diagnostic cancer biomarker with the largest area-under-ROC can be determined objectively. This lipogenic phenotype could be explained by overexpression of fatty acid synthase (FASN) in cancer cells. The diagnostic performance of FFA 18:1-to-ceramide (d18:1/16:0) ratio supports its use for diagnosis of malignant pleural effusions.

  4. Traumatic bilateral renal infarction.

    PubMed

    Peterson, N E

    1989-02-01

    Published examples of unilateral and bilateral renal artery thrombosis attest to their usual subjection to nephrectomy at diagnosis or soon thereafter, eliminating the opportunity for spontaneous improvement which would enlighten the issue of how often late recovery may occur, and under what circumstances. Seven cases of renal artery thrombosis and five patients with renal artery embolization extracted from the literature have included documentation of patchy histologic viability within otherwise total infarction. Conversely, 47 reports of renal artery thrombosis culminating in nephrectomy or examined post mortem include no reference to any of these histologic features. Presumptions are speculative regarding whether these features were absent, overlooked, or unexamined. Their incidence cannot be estimated--only the possibility of recoverable renal function in an unknown number of involved patients. It may be presumed that the majority of kidneys exposed to sustained arterial interruption will undergo irreversible infarction, with an undefined small subgroup later developing renal hypertension. An unknown number, however, may fortuitously possess arterial collateralization competent to support sufficient numbers of viable nephrons to sustain adequate renal function. It is further speculated that shared pathophysiologic features establish the opportunity for misdiagnosis of renal cortical necrosis, which carries a documented potential for spontaneous recovery. Impulsive bilateral nephrectomy may therefore be unjustified, particularly in consideration of the minimal potential hazards of nonremoval. In the event of convalescent problems of renal origin, delayed nephrectomy remains an option. The requirement for interval hemodialysis is further influenced by the advantages accruing from retention of the native kidneys relative to calcium metabolism and blood product replacement. A final consideration relates to the advisability of secondary revascularization of

    Case records of 9 dogs and 5 cats with eosinophilic effusions were reviewed. The animals ranged from 11 months to 13 years old. Seven animals had pleural effusions, 5 had peritoneal effusions, and 2 had pleural and peritoneal effusions. Neoplasia was confirmed in 6 animals and suspected in 1. Eosinophilic pleural effusion was diagnosed 2 days after pneumothorax developed as a consequence of thoracic tube placement in a cat, and pneumothorax was diagnosed in another cat with eosinophilic peritoneal effusion. Other abnormalities seen in 1 or 2 animals associated with eosinophilic effusion were radiographic signs of interstitial or peribronchial pulmonary infiltrates, a history of allergic respiratory tract and skin disease, intestinal lymphangiectasia and lung lobe torsion, chylothorax, bite wounds causing intestinal perforation, and feline leukemia virus infection. Based only on the protein concentration of the effusion, 7 effusions were classified as transudates and 7 were classified as exudates. Five of the 14 animals had eosinophilia (> 1,200 eosinophils/microliters); 3 of these animals had neoplastic disease. Mean eosinophil count in blood samples was not significantly different between animals with neoplasia and those without. Eosinophil counts in blood samples were not linearly related to counts in effusions; however, in some animals the number of eosinophils in the effusion was much higher than the eosinophil count in blood, suggesting concentration of eosinophils in the effusion.

    Pleural biomarkers allowing to mini-invasively discriminate benign from malignant pleural effusions are needed. Among potential candidates, microparticles (MPs) are extracellular vesicles that vectorize antigen derived from the parent cell. We hypothesized that tumor-derived MPs could be present in the pleural liquid and help to identify patients with malignant pleural effusions. Using highly sensitive flow cytometry and cryo-electron microscopy, we showed that large amounts of MPs from hematopoïetic and vascular origin could be detectable in pleural fluids. Their level did not differ between benign (n = 14) and malignant (n = 71) pleural effusions. Analysis of selected tumoral associated antigens (podoplanin, mucin 1 and EpCAM, epithelial-cell-adhesion-molecule) evidenced for the first time the presence of tumor-derived MPs expressing EpCAM in malignant pleural fluids only (Specificity = 93%, Sensitivity = 49% and 45% for flow cytometry and ELISA, respectively). The detection of EpCAM-positive-MPs (EpCAM + MPs) by flow cytometry showed a better specificity and sensitivity than ELISA to distinguish between pleural carcinoma and the others malignant pleural effusions (MPE; Sp: 96% vs 89%; Se: 79% vs 66%). Combining EpCAM+ MPs and cytology improved the diagnosis of MPE compared to cytology alone. This study establishes the basis for using EpCAM+ MPs as a promising new biomarker that could be added to the armamentarium to mini-invasively identify patients with malignant pleural effusions.

    Background: One of the most common indications for pleuroscopy is undiagnosed pleural effusion, which comprises about 25% of all cases of pleural effusions, which remain undiagnosed despite primary tests. Pleuroscopy was performed for the first time in Iran in Masih Daneshvari hospital located in Tehran. The aim of this study was to assess the diagnostic yield of pleuroscopy performed in this center in Iran. Materials and Methods: Three-hundred patients with undiagnosed pleural effusions were enrolled in this study. For all patients, primary tests including pleural effusion analysis, cytology and closed pleural biopsy (if needed) were conducted and all of them were inconclusive. The semirigid thoracoscopy (pleuroscopy) was performed for all patients for diagnostic purposes. Results: Eighty-seven percent of the peluroscopies were diagnostic and 67% of them were diagnosed as malignancy while the rest were diagnosed as tuberculosis. Only 11 patients developed minor complications. Conclusion: In conclusion, pleuroscopy is a safe procedure when performed by a skilled and experienced practitioner; it has a high diagnostic yield and results in only minor complications.

    The evidence base concerning the management of benign pleural effusions has lagged behind that of malignant pleural effusions in which recent randomised trials are now informing current clinical practice and international guidelines.The causes of benign pleural effusions are broad, heterogenous and patients may benefit from individualised management targeted at both treating the underlying disease process and direct management of the fluid. Pleural effusions are very common in a number of non-malignant pathologies, such as decompensated heart failure, and following coronary artery bypass grafting. Pleural fluid analysis forms an important basis of the diagnostic evaluation, and more specific assays and imaging modalities are helpful in specific subpopulations.Options for management beyond treatment of the underlying disorder, whenever possible, include therapeutically aspirating the fluid, talc pleurodesis and insertion of an indwelling pleural catheter. Randomised trials will inform clinicians in the future as to the risks and benefits of these options providing a guide as to how best to manage patient symptoms in this challenging clinical setting.

    The aim is to examine whether the changes in pleural fluid interleukin (IL)-1β, IL-2, IL-6, and IL-8 levels were significant in differential diagnosis of childhood pleural effusions. IL-1β, IL-2, IL-6, and IL-8 levels in pleural fluids of all 36 patients were measured. The levels of IL-1β, IL-2, IL-6, and IL-8 in pleural fluids were statistically significantly higher in the transudate group compared with those of the exudate group. The levels of IL-1β, IL-6, and IL-8 were also found to be statistically significantly higher in the empyema group compared with both the parapneumonic and the tuberculous pleural effusion groups. The levels of IL-2 and IL-6 were detected to be statistically significantly higher in the tuberculous pleural effusion group in comparison with those of the parapneumonic effusion group. The results showed that pleural fluids IL-1β, IL-2, IL-6, and IL-8 could be used in pleural fluids exudate and transudate distinction. PMID:15770060

    To determine the factors affecting the success of bedside talc slurry (TS) used for symptomatic treatment of patients with malignant pleural effusion (MPE). Data of 113 effusions in 103 MPE patients treated between 1999 and 2007 were retrospectively evaluated for the study. The study group involved 73 patients whose follow-up information was available out of 81 patients treated by TS. Causes of MPE were lung cancer in 22 patients (30.1%) and breast carcinoma in 21 patients (28.8%). The success rate of TS was significantly higher if the time period between radiological diagnosis of effusion and administration of TS was less than 30 days (P= .02), or spontaneous expansion was attained after chest tube drainage (CTD) (P= .01). Success rate was higher for patients with daily drainage of less than 200 ml before TS than patients with more than 200 ml of daily drainage (P= .01). Dose of talc, either 4 g or above (P= .34), primary cause of MPE (P= .53), time to termination of CTD (P= .57), amount of drainage when CTD was terminated (P= .23), and time period between CTD and administration of TS (P= .20) did not show a statistically significant effect on the success of TS. In the treatment of malignant pleural effusion, patients with daily drainage of less than 200 ml before TS developed less recurrence than patients with daily drainage of more than 200 ml. Longer time period between the diagnosis of MPE and onset of CTD increased recurrence.

    Anatomical variations of the biceps brachii have been described by various authors, but the occurrence of bilateral asymmetric supernumerary heads is rare and has not been reported. We found three accessory heads of the biceps brachii muscle on right arm and an anomalous third head of biceps brachii on left arm. The third, fourth, and fifth heads of right arm originated from the body of humerus at the insertion site of coracobrachialis and inserted into the distal part of biceps brachii short head in order. The third head of left arm originated from humerus at the insertion site of coracobrachialis and combined with the distal part of biceps brachii and continued to the proximal part of common biceps tendon. Understanding the existence of bilateral asymmetric supernumerary heads of biceps brachii may influence preoperative diagnosis and surgery on the upper limbs. PMID:22025976

    Exudative pleural effusions may arise secondary to inflammation of intra-abdominal structures. Pleural space loculations can complicate these effusions, preventing adequate chest tube drainage and leading to consideration of surgical intervention. Previous studies have demonstrated that intrapleural administration of tissue plasminogen activator (tPA) combined with human recombinant DNase can improve fluid drainage and reduce surgery for patients with loculated parapneumonic effusions; however, the efficacy of this treatment has not been evaluated for complicated pleural effusions attributed to intra-abdominal inflammation. We assessed the safety and efficacy of tPA/DNase for 17 pleural effusions associated with nonmalignant intra-abdominal pathology that did not drain adequately after placement of one or more chest tubes. Efficacy was measured by comparing post- to pretreatment fluid drainage rates, volumetric assessment of pleural fluid on radiographic images before and after treatment, and clinical improvement, including the need for surgical intervention. Symptomatic relief was assessed using the Borg scale for breathlessness. After a median of two doses of tPA/DNase, 23.5% of patients had chest pain and none had pleural bleeding. The volume of pleural fluid drained increased from a median of 325 ml to 890 ml per 24 hours after therapy (P = 0.018). The area of pleural space opacity on chest radiographs decreased from a median of 42.8-17.8% of the hemithorax (P = 0.001). tPA/DNase reduced the pleural fluid volume on chest computed tomographic imaging from a median of 294.4 ml to 116.1 ml. Borg scores improved from a median of 3 (interquartile range = 1-6) to 0 (interquartile range = 0-2) after therapy (P = 0.001). The median duration of chest tube placement and hospital stay were 4 and 11 days, respectively. Two patients required surgical intervention for lung entrapment. Overall, treatment was considered successful for 88.2% of patients

    Different opinions exist as to when chest tube removal should be performed following cardiac surgery. The aim of this study was to compare early chest tube removal with removal of the tubes in the morning day 1 postoperatively. Primary combined end point was the risk of postoperative accumulation of fluid in the pericardial and/or pleural cavities requiring invasive treatment. A retrospective observational cohort study was performed among patients undergoing coronary artery bypass grafting (CABG) and/or conventional valve surgery between July 2010 and June 2013. Patients in whom chest tube output was <150 ml around midnight during the last 4 h were included in the study. These patients were divided into two groups: Group 1 had their chest tubes removed around midnight on the day of surgery, whereas Group 2 kept their tubes until next morning. Using Poisson regression, we estimated crude and adjusted relative risks (RRs) for developing postoperative pleural and/or pericardial effusion within 14 days requiring interventional treatment. A total of 1232 patients underwent CABG, conventional valve or combined surgery during the study period. Of these, 782 patients fulfilled the criteria for early chest tube removal, which was performed in 385 of the patients. A total of 76 patients in Group 1 (20%) and 51 patients in Group 2 (13%) developed postoperative pleural and/or pericardial effusions requiring invasive treatment (P = 0.011). A positive association between early chest tube removal and the development of pleural and/or pericardial effusions was seen [crude RR: 1.54 (95% CI: 1.11-2.13); adjusted RR: 1.70 (95% CI: 1.24-2.33)]. The association became stronger investigating pleural effusions alone (adjusted RR = 1.77; 95% CI: 1.27-2.46), whereas the association with pericardial effusions was less clear. Removal of all chest tubes around midnight on the day of surgery is associated with an increased risk of postoperative pleural and/or pericardial effusions requiring

    Cryptococcus neoformans infection usually presents as chronic meningitis and is increasingly being recognized in immunocompromised patients. Presentation with pleural effusion is rare in cryptococcal disease; in fact, only 4 cases of pleural effusion as the initial clinical presentation in cryptococcosis have been reported in English-language literature to date. We report the first case of pleural effusion as the initial clinical presentation in a renal transplant recipient who was initially misdiagnosed with tuberculous pleuritis but who then developed fungaemia and disseminated cryptococcosis. The examination of this rare manifestation and the accompanying literature review will contribute to increased recognition of the disease and a reduction in misdiagnoses. We describe a 63-year-old male renal transplant recipient on an immunosuppressive regimen who was admitted for left pleural effusion and fever. Cytological examinations and pleural fluid culture were nonspecific and negative. Thoracoscopy only found chronic, nonspecific inflammation with fibrosis in the pleura. After empirical anti-tuberculous therapy, the patient developed an elevated temperature, a severe headache and vomiting and fainted in the ward. Cryptococci were specifically found in the cerebrospinal fluid following lumbar puncture. Blood cultures were twice positive for C. neoformans one week later. He was transferred to the respiratory intensive care unit (RICU) immediately and was placed on non-invasive ventilation for respiratory failure for 2 days. He developed meningoencephalitis and fungaemia with C. neoformans during hospitalization. He was given amphotericin B liposome combined with 5-flucytosine and voriconazole for first 11 days, then amphotericin B liposome combined with 5-flucytosine sustained to 8 weeks, after that changed to fluconazole for maintenance. His condition improved after antifungal treatment, non-invasive ventilation and other support. Further pathological consultation

    In order to analyze the etiology, cytological and biochemical characteristics, and outcome of pleural disease in patients infected with HIV, the medical records of 86 HIV-positive patients with pleural effusion were reviewed. Controls were 106 HIV-negative patients with parapneumonic or tuberculous effusion. Most HIV-positive patients were intravenous drug abusers (95.3%). Pleural effusions in HIV-positive patients were caused by infections in 76 (89.4%) cases. Parapneumonic effusion was diagnosed in 59 patients and tuberculous pleuritis in 15 patients. Staphylococcus aureus was the most frequently isolated bacteria. Parameters for differentiating complicated cases of parapneumonic exudate from uncomplicated cases, such as pleural fluid pH < 7.20 (sensitivity 80% vs. 84.3%), pleural fluid glucose < 35 mg/dl (sensitivity 45% vs. 56.25%) pleural fluid LDH > 1600 UI/l (sensitivity 85% vs. 62.50%), showed similar sensitivity in HIV-positive and HIV-negative patients. Monocytes in pleural fluid were significantly decreased in tuberculous pleuritis in HIV-positive patients (506 +/- 425 vs. 1014 +/- 1196 monocytes/ml, p < 0.05). No significant differences were detected in the outcome of HIV-positive and HIV-negative patients with pleural disease. It can be concluded that the pleural effusion was of predominantly infectious etiology in HIV-positive patients from populations with a high prevalence of intravenous drug abuse. Neither the biochemical parameters in pleural fluid nor the outcome differed significantly between HIV-positive and HIV-negative patients.

    Tuberculous pleural effusions (TPEs) and malignant pleural effusions (MPEs) are difficult to differentiate between in certain clinical situations. Interleukin (IL)-33 is a cytokine that participates in inflammatory responses and may have a role in pleural effusions. The present study aimed to investigate the concentrations and potential differential significance of IL-33 in patients with TPE and MPE. IL-33 levels in pleural effusion and serum samples were detected using sandwich enzyme-linked immunosorbent assay in 23 patients with TPE and 21 patients with MPE. The concentration of IL-33 (mean ± standard deviation) in the TPE patients (22.962±0.976 ng/l) was significantly higher than that in the MPE patients (12.603±5.153 ng/l; P<0.001; z=−4.572); however, there was no significant difference in the serum level of IL-33 in the patients with TPE compared with those with MPE (P>0.05). The concentration of IL-33 in the pleural effusions was positively correlated with that in the serum samples in each group (TPE: r=0.563, P=0.05; MPE: r=0.535, P<0.05). The cut-off value of pleural IL-33 for TPE was 19.86 ng/l, which yielded a sensitivity of 0.869, a specificity of 0.905 and an area under the corresponding receiver operating characteristic curve of 0.903. The present study identified that the level of pleural IL-33 is significantly increased in TPEs and may serve as a novel biomarker to differentiate between patients with TPE and MPE. PMID:24959294

    Twenty-two patients with malignant pericardial effusion were seen at the Toronto General Hospital between 1979 and 1984. Under ECG monitoring, an indwelling Kifa catheter was inserted into the pericardial sac and then connected to a Hemovac system and allowed to drain for 12 to 24 hours. Xylocaine hydrochloride, 100 mg, was first instilled intrapericardially, followed by tetracycline hydrochloride, 500 to 1,000 mg, dissolved in 20 mL normal saline. The catheter was clamped for one to two hours and then allowed to drain into the Hemovac. This procedure was repeated every 24 to 48 hours until the net drainage was less than 25 mL/24 hours. Nine men and 13 women were treated (median age, 55 years). The primary malignancy included lung in 15 patients, breast in two patients, and carcinoma of the stomach, ovary, pleural mesothelioma, chronic granulocytic leukemia, and adenocarcinoma of unknown primary in one patient each. Twenty patients received one to five instillations of tetracycline. In one patient the catheter could not be inserted into the pericardial sac, and in one patient the catheter clotted before tetracycline instillation. Minor complications included transient arrhythmia in two patients, postinjection pain in four patients, and self-limited temperature elevation greater than 38.5 degrees C in two patients. fifteen patients had good control of their malignant pericardial effusion for more than 30 days (median survival, 160 days; range, 38 to 275 days). Three patients died before 30 days without evidence of effusion, and no patient surviving longer than 30 days developed recurrent effusion or pericardial constriction. Intrapericardial tetracycline instillation is a safe and efficacious treatment for malignant pericardial effusion and should be considered the first treatment modality in this situation.

    Background Pleural separation, the “split pleura” sign, has been reported in patients with empyema. However, the diagnostic yield of the split pleura sign for complicated parapneumonic effusion (CPPE)/empyema and its utility for differentiating CPPE/empyema from parapneumonic effusion (PPE) remains unclear. This differentiation is important because CPPE/empyema patients need thoracic drainage. In this regard, the aim of this study was to develop a simple method to distinguish CPPE/empyema from PPE using computed tomography (CT) focusing on the split pleura sign, fluid attenuation values (HU: Hounsfield units), and amount of fluid collection measured on thoracic CT prior to diagnostic thoracentesis. Methods A total of 83 consecutive patients who underwent chest CT and were diagnosed with CPPE (n=18)/empyema (n=18) or PPE (n=47) based on the diagnostic thoracentesis were retrospectively analyzed. Results On univariate analysis, the split pleura sign (odds ratio (OR), 12.1; p<0.001), total amount of pleural effusion (≥30 mm) (OR, 6.13; p<0.001), HU value≥10 (OR, 5.94; p=0.001), and the presence of septum (OR, 6.43; p=0.018), atelectasis (OR, 6.83; p=0.002), or air (OR, 9.90; p=0.002) in pleural fluid were significantly higher in the CPPE/empyema group than in the PPE group. On multivariate analysis, only the split pleura sign (hazard ratio (HR), 6.70; 95% confidence interval (CI), 1.91-23.5; p=0.003) and total amount of pleural effusion (≥30 mm) on thoracic CT (HR, 7.48; 95%CI, 1.76-31.8; p=0.006) were risk factors for empyema. Sensitivity, specificity, positive predictive value, and negative predictive value of the presence of both split pleura sign and total amount of pleural effusion (≥30 mm) on thoracic CT for CPPE/empyema were 79.4%, 80.9%, 75%, and 84.4%, respectively, with an area under the curve of 0.801 on receiver operating characteristic curve analysis. Conclusion This study showed a high diagnostic yield of the split pleura sign and total

    Cerebrospinal fluid otorrhoea is a rare entity. Only a few cases of spontaneous bilateral cerebrospinal fluid otorrhoea have been reported. In all cases, there was a definite time interval between the two (left and right) presentations. To raise awareness and report on the very rare entity of bilateral spontaneous cerebrospinal fluid otorrhoea. This paper reports the case of a bilateral, synchronous, spontaneous cerebrospinal fluid otorrhoea in a 44-year-old female. The patient had grommets surgically inserted on two separate occasions for treatment of otitis media with effusion, and received several courses of oral and topical antibiotics. Five years following the patient's initial presentation, a suspicion of concurrent bilateral cerebrospinal fluid otorrhoea was raised. The otorrhoea sample collected proved to be cerebrospinal fluid. Cross-sectional imaging revealed bilateral defects in the tegmen tympani of the skull base. She underwent staged middle fossa craniotomies to repair the defects. Careful observation of the middle-ear fluid characteristics following myringotomy can allow for prompt diagnosis.

    The longer survival of neoplastic patients achieved through improvements of therapeutic regimens has increased the relative risk of developing a second primary tumour (SPT). In this context, conventional cytopathology can define tumour histotype only in a small fraction of cases. In this study, we have evaluated whether selected combinations of monoclonal antibodies (MAbs) to tumour-associated antigens (TAAs) can increase the accuracy of conventional morphology in detecting second primary tumours (SPTs) in two particularly difficult areas of cytodiagnosis, namely that of effusions and pulmonary fine-needle aspirates (FNAs). The immunocytochemical (ICC) analysis of 334 cytological specimens demonstrated that the use of our selected panel of MAbs could allow a more efficient identification of SPTs in comparison with conventional morphology. This diagnostic improvement was statistically significant (P < 0.0001). The present findings show that the immunophenotyping of effusions and FNAs, providing a more accurate and objective identification of SPTs, may have significant therapeutic and epidemiological relevance.

    To date, most research has been focused on the benign molecules in pleural effusions, and diagnosis of malignant ones still remains challenging. In the present study, targeting the small molecules as potential biomarkers to predict the malignancy of the effusions, the metabolic profiles of 81 clinical pleural effusions (41 malignant effusions from lung cancer and 40 benign ones) were investigated through a NMR-based metabonomic approach. In (1)H NMR analysis, a total of ten small molecules in the effusions were simultaneously determined. Significantly higher mean values of valine, lactate, and alanine and markedly lower signal intensities of acetoacetate, trimethylamine-N-oxide, and α- and β-glucose were observed in malignant pleural effusions compared with those in benign ones. DFA modeling of NMR spectra subjected to a validation allowed the malignant effusions to be discriminated from benign ones in both training and validation groups. Currently, the conventional clinical analyses on chemical constituents in effusions could not provide a reliable prediction of malignancy of the effusions; the present results revealed that the small molecules might serve as useful biomarkers for diagnosis of the effusions, and the present NMR-based metabonomic approach provided a valuable potential to rapidly and sensitively predict the malignancy of the pleural effusions.

    Unexpected pericardial effusions are often found by frontline providers who perform computed tomography. To study the hypothesis that electrocardiographic findings and whether cancer is known or suspected importantly change the likelihood of tamponade for such providers, all unique patients with moderate or large pericardial effusions determined by transthoracic echocardiography during a 6-year period were retrospectively identified. Electrocardiograms were evaluated by blinded investigators for electrical alternans (total and QRS), low voltage (limb leads only, precordial leads only, and both), and tachycardia (>100 QRS complexes/min). Medical records were reviewed to determine whether cancer was known or suspected and whether tamponade was diagnosed. Tamponade was present in 66 patients (27% of 241) with moderate or large pericardial effusions. No tachycardia lowered the odds of tamponade the most (likelihood ratio 0.4, 95% confidence interval 0.3 to 0.6) but by a degree less than any single diagnostic element increased it when present. The combined presence of all 3 electrocardiographic findings and cancer increased the odds of tamponade 63-fold (likelihood ratio 63, 95% confidence interval 33 to 150), whereas their combined absence decreased the odds only fivefold (likelihood ratio 0.2, 95% confidence interval 0.2 to 0.3). In conclusion, electrocardiography findings and cancer rule in tamponade better than they rule it out. Combining these diagnostic elements improves their discriminatory power but not sufficiently enough to rule out tamponade in patients with moderate or large pericardial effusions.

    Transcranial direct current stimulation (tDCS) is an innovative method to explore the causal structure-function relationship of brain areas. We investigated the specificity of bilateral bi-cephalic tDCS with two active electrodes of the same polarity (e.g., cathodal on both hemispheres) applied to intraparietal cortices bilaterally using a combined between- and within-task approach. Regarding between-task specificity, we observed that bilateral bi-cephalic tDCS affected a numerical (mental addition) but not a control task (colour word Stroop), indicating a specific influence of tDCS on numerical but not on domain general cognitive processes associated with the bilateral IPS. In particular, the numerical effect of distractor distance was more pronounced under cathodal than under anodal stimulation. Moreover, with respect to within-task specificity we only found the numerical distractor distance effect in mental addition to be modulated by direct current stimulation, whereas the effect of target identity was not affected. This implies a differential influence of bilateral bi-cephalic tDCS on the recruitment of different processing components within the same task (number magnitude processing vs. recognition of familiarity). In sum, this first successful application of bilateral bi-cephalic tDCS with two active electrodes of the same polarity in numerical cognition research corroborates the specific proposition of the Triple Code Model that number magnitude information is represented bilaterally in the intraparietal cortices.

    The goal of this review is to examine the most recent literature exploring the indications, outcomes, and long-term benefit of bilateral cochlear implantation in children and adults. The indications for cochlear implantation have expanded, as many unilaterally implanted individuals are able to achieve open-set word recognition. Despite the benefits seen in unilateral implantation, many individuals have difficulty perceiving speech in noisy environments. Bilateral cochlear implantation has made great strides in providing individuals access to sound information from both ears, allowing improved speech perception in quiet and in noise, as well as sound localization. Recently, the House Cochlear Implant study group released a position statement in which the group strongly endorsed bilateral cochlear implantation. Improved speech perception in quiet has also been demonstrated by many groups with bilateral implantation. Improved sound localization abilities have been shown to be dependent on interaural level differences. The binaural benefits of head shadow and summation have been long shown in bilaterally implanted individuals. Recently, a growth in squelch has been seen in these individuals likely as a result of increased experience with both implants. This may indicate neural integration of the inputs over time. The literature supports the binaural benefit of bilateral cochlear implantation with demonstrated improved speech perception outcomes in quiet and in noise, sound localization data, and subjective benefits.

    Postoperative pleural effusions are common in patients who undergo cardiac surgery and orthotopic heart transplant. Postoperative pleural effusions may also occur as postcardiac injury syndrome. Most of these effusions are nonspecific and develop as a harmless complication of the surgical procedure itself and generally have a benign course. Here, we investigated the cause and clinical and laboratory features of postoperative early and late pleural effusions in orthotopic heart transplant patients. We retrospectively reviewed the medical records of 50 patients who underwent orthotopic heart transplant between 2004 and 2015 at Baskent University. Patient demographics and clinical and laboratory data, including cause of heart failure, presence of pleural effusions at chest radiography in the first year after transplant, timing of onset, microbiologic and biochemical analyses of pleural effusions, and treatment strategies were noted. Mean age of patients was 39.22 ± 13.83 years (39 men, 11 women). Reason for heart failure was dilated cardiomyopathy in most patients (76%). Nineteen patients (38%) had postoperative pleural effusions, with 15 patients (78.9%) with pleural effusion during the first week after transplant. Of these, 4 patients had recurrent pleural effusion. A diagnostic thoracentesis was performed in 10 patients, with 4 showing transudative effusion and 6 showing exudative effusion secondary to infection (2 patients), postcardiac injury syndrome (1 patient), and hemothorax (3 patients). Aspergillus fumigatus was detected by quantitative culture from pleural effusion in 1 patient. Tube thoracoscopy drainage was performed in 10 patients (25%), and 2 patients received antibiotic therapy. Pleural effusions are frequent after cardiac transplant. Complications may occur in a small portion of patients, with most effusions being nonspecific and having a benign course with spontaneous resolution. Early diagnostic thoracentesis could improve postoperative outcomes

    Transitions between effusive and explosive eruptions, common at silicic volcanoes, can occur between distinct eruptive episodes or can occur as changes between effusive and explosive phases within a single episode. The precise causes of these transitions are difficult to determine due to the multitude of mechanisms and variables that can influence fragmentation thresholds. Numerical modeling of magma ascent within a volcanic conduit allows the influence of key variables to be extensively tested. We study the effect of different variables on the mass eruption rate at the vent using a conservative, 1-D, two-phase, steady-state model that allows for lateral gas loss at shallow depths. Several fragmentation criteria are also tested. We are able to generate a number of regime diagrams for a variety of magma and conduit conditions that constrain transitions from effusive to explosive episodes. We show that a transition to explosive activity can occur without changes in the bulk chemistry, crystal volume fraction, or gas mass fraction of the magma. Eruptive style can be controlled by the pressure gradient within the conduit caused by either overpressure in the chamber or varying lava dome size at the vent. Specific results are sensitive to both magma temperature and conduit geometry. It is important that these variables are well constrained when applying this model to different volcanic systems. We apply our model to the recent activity at Merapi Volcano in Indonesia. We constrain model input and output parameters using current petrologic, seismic, and geodetic studies of the Merapi system, and vary critical parameters over reasonable ranges as documented in the literature. Our model is able to reproduce eruption rates observed during both the 2006 effusive and 2010 explosive/effusive eruptions. Our modeling suggests that a combination of chamber overpressure, increased volatile content, and decreased crystal content due to the voluminous injection of new magma into the

    A patient presented having an acute abdomen on a background of a twelve-month history of worsening asthma. Computed tomography showed giant bilateral intrathoracic hernias extending to both thoracic apices. Our case was unusual as the defect was bilateral and left-sided. Surgical repair revealed each hernia sac measuring >20 cm and to contain the entirety of the small bowel and colon (including retroperitoneal bowel). The appendix was discovered adjacent to right superior pulmonary vein. Both sacs were excised and the defects dissected and transfixed in a single stage operation. In the post-operative stage, he developed a 6.3 cm fluid collection anterior to the right atrium and a left-sided pleural effusion. Morgagni hernias can escape detection and be attributed to other diagnoses courtesy of false localising signs on clinical examination and symptoms in the history.

    A 33-year-old male visited the emergency room with abdominal pain which developed after a vomiting episode. Based on the pneumomediastinum findings from a chest radiograph and a contrast-enhanced chest and abdominal computed tomography scan, the patient was diagnosed with Boerhaave's syndrome. Preoperative radiologic findings showed no pneumothorax or pleural effusion. Once anesthesia was administered, the patient developed near complete cardiopulmonary collapse due to a bilateral tension pneumothorax, which was treated by bilateral thoracentesis, followed by chest tube insertion. Despite a left side rupture, the damaged right lung was unable to overcome single right ventilation, so the surgery was completed via right thoracotomy. The ruptured site was treated, and the patient was transferred to the intensive care unit. We discuss the anesthetic implications of this disease and how to prevent fatal complications.

    Skin toxicity is a ubiquitous side effect in radiotherapy and can be difficult to predict. Moist desquamation in cancer patients can decrease quality of life and occasionally demand unplanned treatment breaks thus worsening outcome. In breast cancer patients, moist desquamation occurs approximately one-third of the time, and while avenues such as intensity-modulated radiation therapy exist to decrease skin side effects, they may be prohibitively expensive to distribute widely. To selectively target patients who are at risk for high skin toxicity, toxicity prediction beyond heuristics is required. This study presents 3D thermal tomography, a translation technology that employs active thermal imaging to map the thermal effusivity of skin. Irradiated mice were imaged throughout reaction development to establish a correlation between effusivity changes and eventual toxicity severity. Female hairless mice (n = 11) were anesthetized and irradiated to 40 Gy in one fraction using a 1 cm Leipzig brachytherapy applicator with an Ir-192 source. After irradiation, thermal imaging was conducted daily with a flash lamp and infrared camera. Effusivity was calculated using custom software and tracked within irradiated and contralateral control regions. Mice were retrospectively grouped into high-grade (moist desquamation present, n = 6) and low-grade (n = 5). All mice showed an increase in the relative average effusivity difference among the treated and control regions between irradiation and peak reaction between 12 and 15 days after irradiation. The high-grade group showed an earlier increase in relative average effusivity difference (mean 1.7 days after irradiation versus 4.4 days after irradiation) than the low-grade group, and had a significantly greater relative average effusivity difference between 2-5 days after irradiation. We concluded that 3D thermal tomography is quick, non-invasive, non-ionizing and exhibited a correlative difference between mice that eventually

OME is characterized as an inflammation with accumulation of secretion in the tympanic cavity, leading to conductive hearing loss. Perception of music in children is assessed using the Montreal Battery of Evaluation of Music Abilities (MBEMA). Listeners are required to judge whether two successive melodies are the same or different on tests of scale, contour, interval and rhythm. They are also queried by a memory test. A total of 92 children (49 girls and 43 boys), aged 6.0-8.0 years (mean 7.3, SD 0.7), attending a music school, were examined using the MBEMA. Twenty-three children were allocated to the OME group, while the remaining 69 to the control group. Age and gender distribution did not differ between children with OME and the controls. All participants had normal bone conduction hearing thresholds. The conductive hearing loss of the children with OME did not exceed 40 dB at any frequency. Their OME was bilateral and had lasted 3-9 months. The obtained scale, rhythm and total MBEMA scores were higher in the control group than in the OME group, with statistically significant differences for scale and rhythm scores. OME can influence music perception in children at the beginning of their school education. OME correlates with both pitch- and rhythm-related aspects of music perception.

    Etiologic diagnosis of an eosinophilic pleural effusion (EPE) presents a diagnostic challenge when intrapleural air and blood have been ruled out as its proximate causes. Among the causes of EPE, those that require immunosuppression for the underlying disease include connective tissue diseases, sarcoidosis, vasculitis, and eosinophilic pneumonia. We present a case of clinically suspected Behcet's syndrome based on a 10-year history of recurrent multiple oral ulcers and human leukocyte antigen-B51 positivity who presented with only an EPE. Computed tomography pulmonary angiogram ruled out central thoracic vein thrombosis but was inconclusive in ruling out a subsegmental pulmonary embolism. The patient declined immunosuppressants and while on follow-up developed bilateral extensive acute lower limb deep venous thrombosis and pulmonary embolism. Upper infrarenal inferior vena cava demonstrated chronic thrombosis suggestive of its antecedent role in pulmonary embolism-related EPE during the first instance. Behcet's syndrome-related EPE can be associated with venous thromboembolism, and immunosuppressive therapy prevents the subsequent thrombotic episodes.

    A simple method is described for the separation of cells derived from effusions of patients with adenocarcinomas in discontinuous density gradients of Percoll. After separation, cells from different fractions were analyzed by morphologic, histochemical and immunologic criteria. Total cell recovery from 27 experiments was 67 +/- 4%. Macrophages (82%) were recovered in the intermediate density fraction (1.056-1.067 g ml-1) with a purity of 90%. Recovered lymphocytes (98%) were found in the high density fraction (1.067-1.077 g ml-1) with a purity of 92%. The majority of the lymphocytes recovered were T cells. Malignant adenocarcinoma cells (90%) were recovered in the lowest density fractions (up to 1.056 g ml-1) with a purity of 79%. Use of effective cell separation procedures should facilitate the analysis of the functional capacities of both normal and neoplastic cells derived from human malignant effusions. PMID:2981542

    Musculoskeletal complaints, which are frequently associated with Lyme disease, often prompt patients to see a physician. In particular, transient episodes of spontaneous knee effusion are common early in the progression of Lyme disease, and, if left untreated, 60% of patients diagnosed with the disease develop Lyme arthritis. This disease is easily treated with antibiotics; therefore, inclusion of Lyme disease in the differential diagnosis as a potential cause of a spontaneous knee effusion can prevent the development of more severe symptoms associated with the disease. However, the time required to receive test results and the inconsistencies between serum and synovial tests can complicate diagnosis of the disease.

    We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect and characterize pleural fluid, and avoids many negative aspects of computerized tomography (CT). Additionally, point-of-care ultrasound can be used to assess pleural fluid volume and character, revealing possible underlying pathologies and guiding management. Thoracentesis performed with ultrasound guidance has lower risk of pneumothorax and bleeding complications. Future research should focus on the clinical-effectiveness of point-of-care ultrasound in the routine management of pleural effusions and how new technologies may expand its clinical utility.

    Pericardial cysts occur rarely, with an incidence rate of 1 per 100,000. They are usually detected by chance and clinically silent in most cases. Pericardial cysts are the most common benign tumours of the pericardium and presents by the third or fourth decade of life, and equally common in males and females. In principle, they only require follow-up, however, an enlarging or symptomatic cyst requires surgical removal. We report a case of a 32 year-old Malay lady, who presented with history of recurrent pericardial effusion followed by right pleural effusion. Computed tomography (CT) thorax identified a large mediastinal cyst as the cause of her problem, requiring exploratory thoracotomy.

    A total of 130 smears from 77 patients with various diseises (42 patients with tumors, 35 patients with specific and non-specific lung diseases) were investigated with enzyme cytochemical methods with regard to the practical application of enzyme cytochemistry in pleural effusions. It is possible to demonstrate all investigated enzymes on normal air-dried or aceton-fixed smears without any technical problems. Between tumor and mesothelial cells a different reaction on some enzymes (alkaline phosphatase, non-specific esterase, aminopeptidase, beta-glucuronidase) could be found valuable for diagnostic purpose. For application in praxi alkaline phosphatase seems to be most important. 70% of all pleural effusions of tumorous origin contain alkaline phosphatase positive tumor cells.

  10. Lava effusion rate definition and measurement--A review

    2007-01-01

    Measurement of effusion rate is a primary objective for studies that model lava flow and magma system dynamics, as well as for monitoring efforts during on-going eruptions. However, its exact definition remains a source of confusion, and problems occur when comparing volume flux values that are averaged over different time periods or spatial scales, or measured using different approaches. Thus our aims are to: (1) define effusion rate terminology; and (2) assess the various measurement methods and their results. We first distinguish between instantaneous effusion rate, and time-averaged discharge rate. Eruption rate is next defined as the total volume of lava emplaced since the beginning of the eruption divided by the time since the eruption began. The ultimate extension of this is mean output rate, this being the final volume of erupted lava divided by total eruption duration. Whether these values are total values, i.e. the flux feeding all flow units across the entire flow field, or local, i.e. the flux feeding a single active unit within a flow field across which many units are active, also needs to be specified. No approach is without its problems, and all can have large error (up to ∼50%). However, good agreement between diverse approaches shows that reliable estimates can be made if each approach is applied carefully and takes into account the caveats we detail here. There are three important factors to consider and state when measuring, giving or using an effusion rate. First, the time-period over which the value was averaged; second, whether the measurement applies to the entire active flow field, or a single lava flow within that field; and third, the measurement technique and its accompanying assumptions.

    Four women with fever, arthromyalgias, pericarditis, pleural effusion, high erythrocyte sedimentation rates, and lymphopenia had mitochondrial antibodies in the serum in the absence of antinuclear antibody. Their illness lasted 5-12 weeks and the antibody test results became negative on remission. Absence of specific bacteriological findings, normal antistreptolysin O titres, resistance to antibiotics, and good response to steroids suggested that these cases represented a milder and less persistent form of the syndrome resembling systemic lupus erythematosus described by German authors.

    Pleural effusions are rarely observed in patients with acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL) and myelodysplastic syndrome (MDS)/myeloproliferative neoplasm (MPN). Therefore the underlying etiology of pleural effusions and the efficacy and safety of pleural procedures in this population has not been well studied. In a retrospective review of cases from 1997 to 2007, we identified 111 patients with acute leukemia or MDS/MPN who underwent pleural procedures. Clinical characteristics were reviewed, and survival outcomes were estimated by Kaplan-Meier methods. A total of 270 pleural procedures were performed in 111 patients (69 AML, 27 ALL, 15 MDS/MPN). The main indications for pleural procedures were possible infection (49%) and respiratory symptoms (48%), and concomitant clinical symptoms included fever (34%), dyspnea (74%), chest pain (24%) and cough (37%). Most patients had active disease (61%). The most frequent etiology of pleural effusions was infection (47%), followed by malignancy (36%). Severe thrombocytopenia (platelet count < 20 × 10(3)/µL) was present in 43% of the procedures, yet the procedural complication rate was only 1.9%. Multivariate analysis revealed that older age, AML, MDS/MPN and active disease status were associated with a shorter median overall survival. Infection and malignant involvement are the most common causes of pleural effusion in patients with acute leukemia or MDS. After optimizing platelet count and coagulopathy, thoracentesis may be performed safely and with high diagnostic yield in this population. Survival in these patients is determined by the response to treatment of the hematologic malignancy.

    Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy. Data for pleural cell differential count from patients receiving thoracentesis during the period from January 2008 to December 2013 were compared with clinical data and established diagnosis of patients obtained via electronic chart review. A total of 6,801 requests of pleural cytology from 3,942 patients with pleural effusion who had received thoracentesis were available at Far Eastern Memorial Hospital from 2008 to 2013, and of these subjects, 115 (2.9%) were found to have EPE. The most frequent cause of EPE was malignancy (33.0%, n=38), followed by parapneumonic effusions (27.8%, n=32), tuberculosis pleuritis (13.9%, n=16), transudate effusions (12.2%, n=14) and the presence of blood or air in pleural space (10.4%, n=12). Additionally, an inverse relationship of eosinophilia in pleural fluid was identified in patients with malignancy and EPE. The cut-off eosinophil count in pleural fluid was 15% for the most accurate discrimination between malignancy and benign disorders in patients with EPE. At the cut-off level, the sensitivity and specificity were 65.8% and 67.5%, respectively. Pleural fluid eosinophilia was a speculative negative predictor for malignancy, despite the fact that cancers, including lung cancers and metastatic cancers to lung, were the most leading cause of pleural fluid eosinophilia. An inverse correlation was observed between the pleural eosinophil percentage and the likelihood of malignancy in patients with EPE.

    diagnostic standard is a pleural biopsy with subsequent histologic examination of the tissue demonstrating invasion by the tumor. The diagnostic tissue is obtained through thoracoscopy or open thoracotomy, both being highly invasive procedures. Thoracocenthesis, or removal of effusion fluid from the pleural space, is a far less invasive procedure that can provide material for cytological examination. However, it is insufficient to definitively confirm or exclude the diagnosis of malignant mesothelioma, since tissue invasion cannot be determined. In this study, we present a computerized method to detect and classify malignant mesothelioma based on the nuclear chromatin distribution from digital images of mesothelial cells in effusion cytology specimens. Our method aims at determining whether a set of nuclei belonging to a patient, obtained from effusion fluid images using image segmentation, is benign or malignant, and has a potential to eliminate the need for tissue biopsy. This method is performed by quantifying chromatin morphology of cells using the optimal transportation (Kantorovich-Wasserstein) metric in combination with the modified Fisher discriminant analysis, a k-nearest neighborhood classification, and a simple voting strategy. Our results show that we can classify the data of 10 different human cases with 100% accuracy after blind cross validation. We conclude that nuclear structure alone contains enough information to classify the malignant mesothelioma. We also conclude that the distribution of chromatin seems to be a discriminating feature between nuclei of benign and malignant mesothelioma cells.

    Background/Purpose Chylothorax is a frequent complication in congenital diaphragmatic hernia (CDH) infants and is associated with significant morbidity. The optimal treatment strategy remains unclear. We hypothesize that octreotide decreases chylous effusions in infants with CDH. Methods This is a retrospective study of all infants with CDH admitted to our institution from October 2006 to October 2011. Results Eleven (12%) infants developed a chylothorax. Five infants were managed conservatively with thoracostomy and total parenteral nutrition. Six infants were started on octreotide therapy. None of the infants required surgical intervention to stop the effusion. There was no significant difference in survival to discharge, length of stay, or average daily chest tube output between groups. There appeared to be a temporally associated drop in chest tube output upon initiation of octreotide in two infants; however, the overall rate of decline in chest tube drainage was unchanged. In addition, there were infants in the conservative group who demonstrated a similar drop in daily chest tube output despite the absence of octreotide. Conclusions Our data suggest that the majority of chylous effusions in CDH infants resolve with conservative therapy alone. PMID:24210190

    A 10-year-old, female spayed Shih Tzu was presented due to weight loss, increased respiratory effort and lethargy, determined to be secondary to a congenital para-esophageal diaphragmatic defect with partial herniation of the stomach and spleen. Four days following reduction surgery of the displaced abdominal organs thoracic effusion developed. Thoracic fluid evaluation revealed a cell-rich, protein-poor modified transudate with neutrophils, reactive mesothelial cells, and atypical epitheloid cells which occasionally appeared to be keratinizing, consistent with neoplastic exfoliation. Thoracic effusion recurred 2 days later, with similar characteristics as the initial sample. Computed tomography (CT) indicated consolidation and displacement of the right middle and accessory lung lobes. Exploratory thoracic surgery demonstrated a thickened, hyperemic right middle lung lobe, and thickened pericardial diaphragmatic ligament. Histologic evaluation of these tissues identified a primary pulmonary adenosquamous carcinoma with intravascular and pleural invasion. Based on these cytologic, histologic, and clinical findings, we conclude that primary pulmonary carcinomas may involve superficial thoracic structures and exfoliate into a thoracic effusion.

    About 20% of hospitalized patients with bacterial pneumonia have an accompanying pleural effusion. Parapneumonic effusions (PPE) are associated with a considerable morbidity and mortality. The main decision in managing a patient with a PPE is whether to insert a chest tube (complicated PPE). Imaging (i.e., chest radiograph, ultrasound and computed tomography) and pleural fluid analysis (i.e., pH, glucose, lactate dehydrogenase, bacterial cults) provide essential information for patient management. Therefore, all PPEs should be aspirated for diagnostic purposes. This may require image-guidance if the effusion is small or heavily loculated. According to the current guidelines, any PPE that fulfills at least one of the following criteria should be drained: size > or = 1/2 of the hemithorax, loculations, pleural fluid pH < 7.20 (or alternatively pleural fluid glucose < 60 mg/dl), positive pleural fluid Gram stain or culture, or purulent appearance. The key components of the treatment of complicated PPE and empyema are the use of appropriate antibiotics, provision of nutritional support, and drainage of the pleural space by one of the following methods: therapeutic thoracentesis, tube thoracostomy, intrapleural fibrinolytics, thoracoscopy with breakdown of adhesions or thoracotomy with decortication. The routine use of intrapleural fibrinolytic therapy remains controversial. (c) 2009 Elsevier España, S.L. All rights reserved.

    To determine the exact incidence of lung cancer, pulmonary emphysema and pleural effusion we decided to carry out an autopsy study. In this autopsy study carried out over two years, we compared the results of autopsy findings with the clinical data in accompanying records of the deceased. Among the 708 deceased subjects, there were 398 males and 310 females with a median age of 71 years. At autopsy, 55 cases of lung carcinoma (BCA) were found, of which 24 have not been identified during life (44%). Among the deceased with BCA, emphysema was also observed at autopsy in 40% of the cases. Pulmonary emphysema was described macroscopically in 28% of the full set of 708 deceased, whereas the accompanying records of the deceased described this condition in only 12% of the cases. Microscopic changes compatible with emphysema were identified in 54% of the examined lungs. Pleural effusions were described in the accompanying records of 13% of the deceased, while the autopsies showed this condition in 33% of the deceased. BCA was accompanied by effusion in 25% of the cases. The obtained results show that the studied conditions are present in more cases than are reported by clinicians. The study confirms the commonly accepted association between lung cancer and emphysema.

    Neurotrophins (NTs) modulate the growth of human malignancies, including lung cancers. Our prospective study evaluated the accuracy of pleural NTs [nerve growth factor, brain-derived neurotrophic factor (BDNF), neurotrophin 3 (nT3) and 4 (nT4)] levels for differentiating benign from malignant pleural exudates. Levels of NTs were measured by ELISA in 170 patients with non-neutrophilic (<50%) exudative benign or malignant pleurisies diagnosed by pleuroscopy. Fifty-nine benign (9 infections and 50 inflammatory diseases) and 111 malignant (50 extrathoracic tumors, 51 lung cancers and 10 mesotheliomas) pleural exudates were diagnosed by thoracoscopy. Levels of BDNF were significantly higher in malignant than in benign effusions [17 pg/ml (0–367) vs. 8 pg/ml (0–51), p<0.05]. ROC analysis showed an area under the curve of 0.609 (p=0.012; best threshold 44 pg/ml). Pleural BDNF levels were significantly higher in pleural metastasis of pulmonary tumors and in mesothelioma than in pleural benign effusions. Finally, a higher proportion of pleural nT3 was detected in squamous cell lung carcinoma in comparison to that in non-squamous cell lung carcinoma (72.7 vs. 10%, p<0.0001). NTs and particularly BDNF may play a role in the pathogenesis of malignant pleural effusions. PMID:22977602

    Objectives. To study the diagnostic value of pleural fluid cholesterol in differentiating transudative and exudative pleural effusion. To compare pleural fluid cholesterol level for exudates with Light's criteria. Design. Cross sectional descriptive study. Settings. Medical wards of Tribhuvan University Teaching Hospital. Methods. Sixty two cases of pleural effusion with definite clinical diagnosis admitted in TUTH were taken and classified as transudates (19) and exudates (43). The parameters pleural fluid protein/serum protein ratio (pfP/sP), pleural fluid LDH/ serum LDH ratio, pleural fluid LDH (pfLDH) and pleural fluid cholesterol (pCHOL) were compared with clinical diagnosis with regard to their usefulness for distinguishing between pleural exudates and transudates. Results. The pCHOL values determined were 1.92 ± 0.75 for exudates, 0.53 ± 0.28 for transudates, the differences between the transudates and others are statistically significant (P < 0.0001). It is seen that pfP/sP ratio has a sensitivity of 81.4% and specificity of 82.6%; pfLDH/sLDH ratio has a sensitivity of 86% and specificity of 94.7% and pCHOL with sensitivity of 97.7% and specificity of 100% for differentiating exudative and transudative PE. Conclusion. The determination of pCHOL is of great value for distinguishing between pleural exudates and transudates and should be included in routine laboratory analysis of pleural effusion.

    OBJECTIVES: Pleural effusion is a common diagnostic and clinical problem. The differential diagnosis of pleural effusion may be difficult and may require several procedures, including invasive ones. Certain studies have investigated biochemical parameters to facilitate the diagnosis of exudative pleural effusion; however, it remains a challenging problem in clinical practice. We aimed to investigate the potential role of the neutrophil-lymphocyte ratio, which can be easily obtained by determining the cell count of the pleural fluid, in the differential diagnosis of exudative pleural effusion. METHODS: Records from patients who underwent thoracentesis and pleural fluid analysis between May 1, 2013, and March 1, 2015, were obtained from the electronic database of our hospital. The patients who met the inclusion criteria were divided into five groups according to their diagnosis: malignant pleural effusion, para-malignant pleural effusion, para-pneumonic effusion, tuberculosis-related effusion or other. The neutrophil-lymphocyte ratio value was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. The patient groups were compared according to the given parameter. RESULTS: A total of 465 patients who met the inclusion criteria among 1616 patients with exudative pleural effusion were included in the study. The mean neutrophil-lymphocyte ratio value was significantly lower in tuberculosis-related pleural effusion compared to malignant, para-pneumonic and para-malignant effusions (p=0.001, p=0.001, p=0.012, respectively). The areas under the curve for tuberculosis pleurisy compared to malignant, para-pneumonic and para-malignant effusions were 0.38, 0.36, and 0.37, respectively. Lower cut-off values had higher sensitivity but lower specificity for tuberculosis pleurisy, while higher cut-off values had higher specificity but lower sensitivity for this condition. CONCLUSION: The pleural fluid neutrophil-lymphocyte ratio, which is an

    The incidence, characteristics of pleural effusions due to pulmonary thromboembolism (PTE) have been reported previously. However, the impact of pleural effusions on the prognosis of acute PTE patients and the involved influencing factors remain unclear. A total of 518 consecutive PTE patients were enrolled in Beijing Chao-Yang Hospital from January 2009 to April 2014. The diagnosis was confirmed with Spiral computer tomography pulmonary angiography or/and high-probability ventilation and perfusion scans. All patients finished one-year clinical follow-up. Among 518 patients with acute PTE, pleural effusions were found in 120 patients (23.2 %). No strictly tight association between side of pleural effusions and location of thrombus was observed. The diagnosis time between patients of PTE with pleural effusions and without pleural effusions had no statistically significant difference. During the 3-month follow-up, the all-cause mortality of PTE patients with pleural effusions was significantly higher than those without pleural effusions [10/120 (8.3 %) vs. 8/398 (2.0 %)]. During the 1-year follow-up, analysis of survival also showed that all-cause mortality was significantly higher in PTE patients with pleural effusions than those without pleural effusions. In both univariate Cox-regression analysis [P < 0.001, HR 3.044, 95 % CI (1.647, 5.625)] and multivariate Cox-regression analysis [P < 0.05, HR 2.040, 95 % CI (1.038, 4.009)] pleural effusions showed to be risk factor of poor prognosis. Pleural effusions in patients with acute PTE were significantly correlated with higher mortality. Pleural effusions in acute PTE patients might be used as a predictive parameter for prognosis.

    Objective Although tuberculous pleural effusion (TPE) is commonly characterized by lymphocytic predominance and high adenosine deaminase (ADA) levels, it may present with neutrophilic predominance or low ADA levels, which are more commonly found in parapneumonic effusion (PPE) or malignant pleural effusion (MPE), respectively. A few studies have observed that the atypical pleural fluid profiles of these cases of TPE may resolve at follow-up thoracentesis. However, these observations were incompletely analyzed and lacked comparison with proper control groups. Thus, limited data are available comparing the sequential pleural fluid changes between TPE and PPE or MPE with similar pleural fluid profiles. Methods TPE, PPE, and MPE patients who underwent sequential thoracentesis were retrospectively reviewed. The sequential changes in the pleural fluid profiles were compared between neutrophilic TPE and PPE, and lymphocytic TPE and MPE with low ADA levels. Results Twenty-three TPE patients (16 with neutrophilic exudates, seven with lymphocytic exudates), 72 cases of PPE with neutrophilic exudates, and 18 cases of MPE with lymphocytic exudates were included in the analysis. A sequential shift to lymphocytic exudates occurred significantly more often in TPE than in PPE cases. The initial and follow-up ADA levels in TPE cases with a lymphocytic shift were significantly higher than those in PPE cases with a lymphocytic shift. The ADA levels in the TPE cases with initial lymphocytic exudates and low ADA levels significantly increased at follow-up thoracentesis. For the TPE and MPE cases with initial lymphocytic exudates and ADA levels <40 U/L, the frequency of effusion with ADA levels ≥40 U/L at the second thoracentesis was significantly higher in the TPE cases. Conclusion Follow-up thoracentesis may provide useful information for clinical decision-making in suspected atypical TPE cases with neutrophilic exudates or low ADA levels.

    Pleural effusion is one of the most common complications of lung adenocarcinoma and is diagnostically challenging. This study aimed to investigate the diagnostic performance of carcinoembryonic antigen (CEA), cytokeratin fragment (CYFRA) 21-1, and cancer antigen (CA) 19-9 for lung adenocarcinoma-associated malignant pleural effusion (MPE) through a validation study and meta-analysis. Pleural effusion samples were collected from 81 lung adenocarcinoma-associated MPEs and 96 benign pleural effusions. CEA, CYFRA 21-1, and CA19-9 were measured by electrochemiluminescence immunoassay. The capacity of tumor markers was assessed with receiver operating characteristic curve analyses and the area under the curve (AUC) was calculated. Standard methods for meta-analysis of diagnostic studies were used to summarize the diagnostic performance of CEA, CYFRA 21-1, and CA19-9 for lung adenocarcinoma-associated MPE. The pleural levels of CEA, CYFRA 21-1, and CA19-9 were significantly increased in lung adenocarcinoma-associated MPE compared to benign pleural effusion. The cut-off points for CEA, CYFRA 21-1, and CA19-9 were optimally set at 4.55 ng/ml, 43.10 μg/ml, and 12.89 U/ml, and corresponding AUCs were 0.93, 0.85, and 0.81, respectively. The combination of CEA, CYFRA 21-1, and CA19-9 increased the sensitivity to 95.06%, with an AUC of 0.95. Eight studies were included in this meta-analysis. CEA showed the best diagnostic performance with pooled sensitivity, specificity, positive/negative likelihood ratio, and diagnostic odds ratio of 0.75, 0.96, 16.01, 0.23, and 81.49, respectively. The AUC was 0.93. CEA, CYFRA 21-1, and CA19-9 play a role in the diagnosis of lung adenocarcinoma-associated MPE. The combination of these tumor markers increases the diagnostic accuracy.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    We report a personal series of 28 patients with neurofibromatosis 2 (NF-2), emphasizing the differences from classical NF-1. The hallmark of NF-2 is bilateral acoustic neuromas with initial symptoms usually occurring in the second or third decade. The natural history may lead to bilateral deafness, but hearing loss may also be a complication of surgery. NF-2 is frequently accompanied by additional intracranial tumors (particularly multiple meningiomas). Half of our patients had a spinal space-occupying lesion. NF-2 is inherited as an autosomal dominant trait, and many patients appear to represent new mutations.

    The purpose of this study was to investigate whether the expression of AQP-1 on the pleura is altered in a rat model with a tuberculous pleural effusion (TPE) and to study its function. A TPE model was established by intrapleural inoculation with 0.03 mg (2 ml) standard tuberculosis bacillus (H(37)Rv). The rats with TPE were sacrificed at different time points (day 1, 3, or 5) after inoculation. The control group received a 2-ml intrapleural injection of saline. The visceral and parietal pleural tissues were harvested and processed for real-time RT-PCR, Western blot, immunohistochemistry, and determination of tissue AQP-1 levels. Recombinant adenovirus Ad-rAQP-1 containing full-length cDNA of AQP-1 was constructed. Six groups of seven Wistar rats were assigned to receive the following treatments: group 1: intrapleural administration of normal saline; group 2: intrapleural administration of tuberculosis bacilli (TB); group 3: intrapleural inoculation with TB at day 7 following intrapleural administration of Ad-rAQP-1 vector; group 4: intrapleural inoculation with 0.03 mg TB at day 7 following intrapleural administration of control Ad-GFP vector; group 5: intrapleural administration of Ad-rAQP-1; group 6: intrapleural administration of control Ad-GFP vector. The expression of AQP-l on the pleural tissue was detected by immunohistochemistry and Western blot analysis. Histopathologic changes of the pleura and the volume of pleural fluid were examined on day 7 following gene intervention or on day 3 following TB inoculation. Bilateral pleural effusions appeared within 5 days in all rats who received an intrapleural inoculation with TB. The peak amount of pleural fluid occurred on day 3. The AQP-1 expression at protein and mRNA was increased in the early phase of TPE. The expression of AQP-1 was increased in the Ad-rAQP-1 gene transfer group, indicating successful adenovirus gene transfer. The volume of pleural fluid in group 3 (6.1 +/- 0.7 ml) was significantly

    Pleural effusion is a common clinical problem that can complicate many medical conditions. Breathlessness is the most common symptom of pleural effusion of any cause and the most common reason for pleural drainage. However, improvement in breathlessness following drainage of an effusion is variable; some patients experience either no benefit or a worsening of their breathlessness. The physiological mechanisms underlying breathlessness in patients with a pleural effusion are unclear and likely to be multifactorial with patient-related and effusion-related factors contributing. A comprehensive study of the physiological and symptom responses to drainage of pleural effusions may provide a clearer understanding of these mechanisms, and may identify predictors of benefit from drainage. The ability to identify those patients whose breathlessness will (or will not) improve after pleural fluid drainage can help avoid unnecessary pleural drainage procedures, their associated morbidities and costs. The PLeural Effusion And Symptom Evaluation (PLEASE) study is a prospective study to comprehensively evaluate factors contributing to pleural effusion-related breathlessness. The PLEASE study is a single-centre prospective study of 150 patients with symptomatic pleural effusions that require therapeutic drainage. The study aims to identify key factors that underlie breathlessness in patients with pleural effusions and develop predictors of improvement in breathlessness following effusion drainage. Participants will undergo evaluation pre-effusion and post-effusion drainage to assess their level of breathlessness at rest and during exercise, respiratory and other physiological responses as well as respiratory muscle mechanics. Pre-drainage and post-drainage parameters will be collected and compared to identify the key factors and mechanisms that correlate with improvement in breathlessness.

    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, p<0.001]. CT attenuation values had a close correlation with the pericardial fluid albumin (r=0.829), protein (r=0.752), and LDH (r=0.708) levels; WBC count (r=0.564); protein ratio (r=0.739); and LDH ratio (r=0.689) as well as the albumin gradient (r=-0.725). A cut-off value of 4.7 HU had 80% sensitivity and 87.7% specificity for the identification of exudative pericardial effusion. 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.

    It is important for diagnosis of pulmonary diseases to measure volume of accumulating pleural effusion in threedimensional thoracic CT images quantitatively. However, automated extraction of pulmonary effusion correctly is difficult. Conventional extraction algorithm using a gray-level based threshold can not extract pleural effusion from thoracic wall or mediastinum correctly, because density of pleural effusion in CT images is similar to those of thoracic wall or mediastinum. So, we have developed an automated extraction method of pulmonary effusion by use of extracting lung area with pleural effusion. Our method used a template of lung obtained from a normal lung for segmentation of lungs with pleural effusions. Registration process consisted of two steps. First step was a global matching processing between normal and abnormal lungs of organs such as bronchi, bones (ribs, sternum and vertebrae) and upper surfaces of livers which were extracted using a region-growing algorithm. Second step was a local matching processing between normal and abnormal lungs which were deformed by the parameter obtained from the global matching processing. Finally, we segmented a lung with pleural effusion by use of the template which was deformed by two parameters obtained from the global matching processing and the local matching processing. We compared our method with a conventional extraction method using a gray-level based threshold and two published methods. The extraction rates of pleural effusions obtained from our method were much higher than those obtained from other methods. Automated extraction method of pulmonary effusion by use of extracting lung area with pleural effusion is promising for diagnosis of pulmonary diseases by providing quantitative volume of accumulating pleural effusion.

    Thenar hammer syndrome is a very rare condition that mimics rheumatic diseases such as carpal syndrome tunnel, Raynaud's phenomenon, and hand synovitis. To describe the sonographic presentation of thenar hammer syndrome in a typical patient. Grey-scale sonography and colour Doppler imaging of the hands with an iU22 scanner (Philips) were performed. In B mode, the lesion was seen as a large, rounded, heterogeneous area combining hypoechoic and echogenic components. Pseudoaneurysm was diagnosed based on presence of a cystic saccular formation arising directly from the adjacent artery and exhibiting an irregular thick wall with turbulent blood flow in the lumen. Colour Doppler showed blood flow in part of the lumen, the rest of which was filled with a thrombus seen as echogenic tissue. Sonography can help to diagnose thenar hammer syndrome. Angiography may be unnecessary in patients with normal colour Doppler findings. Copyright © 2010 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

    Most tumors arising in the nasopharynx are malignant and frequently develop otitis media with effusion (OME). On the contrary, benign nasopharyngeal tumors are very rare, and pleomorphic adenoma, which is a benign mixed tumor of the nasopharynx, is also rarely encountered. We herein report a case of nasopharyngeal pleomorphic adenoma which initially presented as OME. This tumor completely blocked the orifice of the Eustachian tube but was removed by a combination of transnasal and transoral endoscopic resection. A defect in the mucous membrane was covered with polyglycolic acid sheet and fibrin glue. Mucous membrane completely covered the exposed tubal cartilage without adhesion near the tubal orifice. OME and hearing loss completely subsided 3 months after the surgery. She was disease-free 2 years after the surgery. Use of polyglycolic acid sheet could be a feasible mesh for closure of surgical defect without scarring, and it also led to healing of OME. © 2013.

    Constrictive pericarditis is a clinical condition characterized by the appearance of signs and symptoms of right heart failure due to loss of pericardial compliance. Cardiac surgery is now one of the most frequent causes in developed countries, while tuberculosis remains the most prevalent cause in developing countries. Malignancy is a rare cause but usually has a poor prognosis. The diagnosis of constrictive pericarditis remains a clinical challenge and requires a combination of noninvasive diagnostic methods (echocardiography, cardiac magnetic resonance and computed tomography); in some cases, cardiac catheterization is needed to confirm the diagnosis. The authors present the case of a 51-year-old man, hospitalized due to cardiac tamponade. Diagnostic investigation was suggestive of tuberculous etiology. Despite directed medical therapy, the patient developed effusive-constrictive physiology. He underwent pericardiectomy and anatomopathologic study suggested a neoplastic etiology. The patient died in the postoperative period from biventricular failure.

    We present a case of drug-induced pericardial effusion in a patient with end-stage renal disease. Hypertension is frequent among patients with chronic renal failure and sometimes it is necessary to use agents, like minoxidil. Many papers have reported the association between minoxidil and pericardial effusion, both in dialysis patients and those with normal renal function. These effusions sometimes require drainage because of tamponade, but usually disappear after discontinuation of the drug, which is what happened in our patient. In any patient on dialysis treated with minoxidil, the appearance of pericardial effusion unresponsive to ultrafiltration should launch the suspicion of this complication and the drug should be withdrawn.

    Pericardial effusions can cause considerable morbidity and potentially may lead to mortality. Malignant pericardial effusions are uncommon, and data on malignancies encountered in pericardial effusion cytology specimens are limited. Relevant records of all pericardial effusions from January 2008 to September 2014 were examined and compared with pericardial biopsy results when performed. Discrepant cases were reviewed to determine the cause of the disagreement. In total, 419 pericardial effusion specimens obtained from 364 patients were examined. Cytologic diagnostic categories included: negative for malignancy (332 specimens; 79%), equivocal (25 specimens; 6%), and positive (62 specimens from 51 patients; 15%). Forty-seven patients who had positive effusions were known to have malignancy. The most common primary malignancies were breast (39.3%) and lung (39.3%) cancers in women and lung cancer (47.4%) in men. A concurrent pericardial biopsy was performed in 46% of patients. Excluding equivocal cytologic diagnoses, cytology and biopsy were concordant in 153 of 173 paired samples (88.4%). The sensitivity of cytology in diagnosing malignancy was 92.1% compared with 55.3% for pericardial biopsy. Cytologic examination has significant diagnostic utility in the evaluation of pericardial effusions and exhibits a lower false-negative rate compared with pericardial biopsy. Submission of pericardial biopsy alongside effusion cytology is associated with increased sensitivity for detecting malignancy and may be especially useful in the setting of low-volume pericardial effusion.

    Background: After pneumonia, cancer involving the pleura is the leading cause of exudative pleural effusion. Cytologic examination of pleural effusions is an important initial step in management of malignant effusions. The aim of this study is to evaluate the spectrum of uncommon malignant pleural effusions in a chest disease center in Turkey. Materials and Methods: A retrospective study of samples of pleural effusions submitted to Ataturk Chest Diseases and Chest Surgery Education and Research Hospital Department of Pathology between March 2005 and November 2008 was performed. Results: Out of a total of 4684 samples reviewed 364 (7.8%) were positive for cancer cells. Of the malignant pleural effusions 295 (81%) were classified as adenocarcinoma or carcinoma not otherwise specified (NOS). Pleural effusion specimens revealing a diagnosis other than adenocarcinoma/carcinoma NOS were: 32 (8.8%) malignant mesotheliomas, 14 (3.8%) small cell carcinomas, 13 (3.5%) hematolymphoid malignancies and 10 (2.7%) squamous cell carcinoma. Hematolymphoid malignancies included non- Hodgkin lymphoma (diffuse B large cell lymphoma, mantle cell lymphoma), multiple myeloma, chronic myeloid leukemia, and acute myeloid leukemia. Conclusions: Despite that adenocarcinoma is the most common cause of malignant pleural effusions, there is a significant number of hematological and non-hematological uncommon causes of such effusions. Cytopathologists and clinicians must keep in mind these uncommon entities in routine practice for an accurate diagnosis. PMID:21799700

    Recurrent pleural effusions are frequently encountered in clinical practice. Whether malignant or nonmalignant, they often pose a challenge to the practicing clinician. When they recur, despite optimum medical therapy of the underlying condition and repeated thoracenteses, more invasive definitive approaches are usually required. Since its introduction in 1997, the PleurX catheter became the preferred method to treat recurrent malignant pleural effusions. Since then, a number of publications have documented its utility in managing recurrent nonmalignant pleural effusions. The purpose of this paper is to review the use of the PleurX catheter in recurrent pleural effusions. © The Author(s), 2016.

    Besides massive expression in inflammatory pleural effusions, inflammatory markers are also present in cancerinduced pleural effusions. Recent advances in cancer biology point to a role of inflammatory signaling in cancer and encourage reconsidering the diagnostic and prognostic value of inflammatory markers. Here an attempt was made to relate protein levels of inflammatory markers to underlying malignant processes in the pleural space. Pleural effusions from lung cancer patients (n=116) were subjected to a multifactorial analysis covering 13 inflammatory markers. The composition of tumor-associated effusions was compared with that of parainflammatory pleural effusions (n=30), transudates (n=18), and serum values, and evaluated in relation to cancer origin, histology, cytology, pleural involvement, treatment history, and survival time. Inflammatory markers were significantly expressed in pleural effusions of paraneoplastic origin when compared to transudates and most serum levels. Values in pleura-invading and metastatic tumor-associated effusions were typically higher than those of other tumors. Many markers correlated negatively with survival, most prominently IL-8 (r=-0.36, p=0.001) and VEGF (r=-0.35, p=0.001). It appears that most inflammatory markers are highly expressed in tumor-associated pleural effusions, reflecting to some extent tumor origin and localization. Despite the lower efficacy of inflammatory markers in the differentiation between exudative pleural effusions, some inflammatory markers may represent potential prognostic markers of malignant processes in the pleural space.

  4. Mechanism of Highly Synchronized Bilateral Hippocampal Activity

    In vivo studies of epileptiform discharges in the hippocampi of rodents have shown that bilateral seizure activity can sometimes be synchronized with very small delays (< 2 ms). This observed small time delay of epileptiform activity between the left and right CA3 regions is unexpected given the physiological propagation time across the hemispheres (> 6 ms). The goal of this study is to determine the mechanisms of this tight synchronization with in-vitro electrophysiology techniques and computer simulations. The hypothesis of a common source was first eliminated by using an in-vitro preparation containing both hippocampi with a functional ventral hippocampal commissure (VHC) and no other tissue. Next, the hypothesis that a noisy baseline could mask the underlying synchronous activity between the two hemispheres was ruled out by low noise in-vivo recordings and computer simulation of the noisy environment. Then we built a novel bilateral CA3 model to test the hypothesis that the phenomenon of very small left-to-right propagation delay of seizure activity is a product of epileptic cell network dynamics. We found that the commissural tract connectivity could decrease the delay between seizure events recorded from two sides while the activity propagated longitudinally along the CA3 layer thereby yielding delays much smaller than the propagation time between the two sides. The modeling results indicate that both recurrent and feedforward inhibition were required for shortening the bilateral propagation delay and depended critically on the length of the commissural fiber tract as well as the number of cells involved in seizure generation. These combined modeling/experimental studies indicate that it is possible to explain near perfect synchronization between the two hemispheres by taking into account the structure of the hippocampal network.

    Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. We report the combined experience of two children's hospitals in one city over a 20-year period. We encountered nine cases of synchronous bilateral nephroblastoma (National Wilms' Tumor Study 3, stage V). Age at diagnosis ranged from 9 to 41 months (mean 23 months). There were five girls and four boys. Associated findings include nephroblastomatosis in three cases (33%), one of which also had a familial history; undescended testis in two cases; and minor anomalies in two other cases. Surgical treatment consisted of unilateral nephrectomy with contralateral partial nephrectomy or tumorectomy in six cases, nephrectomy with contralateral biopsy only in two cases, and the other patient had bilateral biopsies initially, followed at a later date by partial nephrectomy on one side. All patients received chemotherapy; actinomycin D (AMD) only was used in the oldest case, vincristine and AMD in five cases, to which was added cyclophosphamide in one case and adriamycin in two. Seven patients received radiation therapy. Seven out of the nine patients survived more than 2 years (77%); five are well, off chemotherapy, with no evidence of disease from 4 to 11 years after diagnosis. Two patients suffered from chronic renal failure and one died from complications after renal transplantation more than 19 years after diagnosis. The two patients who died from their disease presented with more advanced tumor. Therefore, the agressiveness of multimodal therapy can be tailored according to stage and histology, and effective chemotherapy allows maximal preservation of renal parenchyma in patients with stage I and II tumors.

    CONTEXT: Prevalence of tuberculous pleural effusion is very high in the Asian subcontinent but very few studies have come up from this part of the world about the course of recovery of pulmonary functions after institution of anti-tubercular therapy (ATT) and thoracentesis. AIMS: To study initial lung function impairment, changes over time after institution of ATT and thoracentesis and residual abnormalities left at the end of six months of treatment. SETTINGS AND DESIGN: Randomized open level interventional study over two years in 52 patients at a tertiary level teaching hospital. METHODS: The study population was divided into two equal groups, A (therapeutic thoracentesis) and B (diagnostic thoracentesis). Spirometry, chest radiograph and ultrasonography of thorax were done initially and at each follow-up visit up to six months. Statistical analysis was done (P value < 0.05 considered significant). RESULTS: Both groups were comparable initially. After six months none in group A and five patients in group B had minimal pleural effusion. During follow up, mean percentage predicted of FEV1 and FVC increased more in A than in B and the differences were statistically significant (P < 0.05). Pleural thickening, initially absent in both groups, was found to be more in B as compared to A at subsequent follow-up visits and this was statistically significant (P < 0.05). CONCLUSIONS: Thoracentesis should be considered in addition to anti-TB treatment, especially in large effusions, in order to relieve dyspnea, avoid possibility of residual pleural thickening and risk of developing restrictive functional impairment.

    The aim of this study was to investigate the pleural and systemic expression of interleukin-18 (IL-18) in patients with pleural effusions (PEs), and the effects of the cytokine in mouse pleural space. One hundred and sixty patients, 23 with pleural effusions (PEs) due to heart failure, 60 malignant, 25 parapneumonic/empyemas, 15 tuberculous and 37 with exudates of miscellaneous etiologies were included in the study. Pleural fluid (PF) and serum IL-18 content was determined using ELISA. IL-18 was injected intrapleurally in mice and pleural inflammation was assessed using pleural lavage. The highest PF IL-18 levels were observed in parapneumonic PEs and the lowest PF IL-18 levels in patients with exudates of miscellaneous aetiologies and transudates. PF IL-18 levels were significantly higher in patients with empyemas compared to those with uncomplicated (p=0.009) or complicated (p=0.028) parapneumonic effusions, while serum levels did not differ significantly among the three groups. Pleural IL-18 content was higher than that of blood only in patients with empyemas. In patients with pleural exudates of all etiologies and in those with parapneumonic PEs/empyema, PF IL-18 levels were correlated with markers of acute pleural inflammation such as the percentage of PF neutrophils, PF LDH and PF/serum LDH ratio, low PF glucose and PF/serum glucose ratio and low PF pH. In mice, intrapleural IL-18 caused neutrophil-predominant pleural inflammation. In conclusion, IL-18 is linked to the intensity of neutrophilic pleural inflammation in patients with PEs, it is up-regulated in the pleural space of patients with empyema and it stimulates the accumulation of neutrophils in mouse pleura.

    2011-07-01

    Chemical pleurodesis is widely used in symptomatic patients with malignant pleural effusion to relieve symptoms, prevent fluid recurrence, and improve quality of life. Talc has been repeatedly found to be the most effective sclerosant agent, and thoracoscopic talc poudrage has been found to be the most effective pleurodesis technique. A homogeneous talc distribution on the visceral and parietal pleura helps to achieve complete pleural symphysis. We have recently adopted a new suitable sterile device that delivers talc under low and constant pressure, facilitating uniform coating of the whole pleural surface and avoiding inappropriate deposition of talc clumps.

    Olivine is the major mineral in the Earth's upper mantle occurring predominantly in igneous rocks and has been identified in meteorites, asteroids, the Moon and Mars. Among many other important applications in planetary and materials sciences, the thermodynamic properties of vapor species from olivine are crucial as input parameters in computational modelling of the atmospheres of hot, rocky exoplanets (lava planets). There are several weight loss studies of olivine vaporization in the literature and one Knudsen Effusion Mass Spectrometry (KEMS) study. In this study, we examine a forsterite-rich olivine (93% forsterite and 7% fayalite, Fo93Fa7) with KEMS to further understand its vaporization and thermodynamic properties.

    We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this design, we demonstrate an atomic lithium source suitable for trapped-atom experiments. At a nozzle temperature of 525 °C, the collimated atomic beam flux directly after the nozzle is 1.2 × 10{sup 14} atoms/s with a peak beam intensity greater than 5.0 × 10{sup 16} atoms/s/sr. This suggests an oven lifetime of several decades of continuous operation.

    We report a rare case of a 59 year-old female, who was admitted to the hospital because of a recurrent right-sided pleural effusion. The initial work-up was non-diagnostic. The diagnosis was finally confirmed following medical thoracoscopy, where an osteophyte of a rib was found to protrude sharply into the thoracic cavity. Chronic inflammatory changes of the pleura suggested mechanical irritation due to long lasting friction between this bony structure and the underlying lung. This is the first report where an osteophyte seems to be implicated in pleural pathology. A brief review of the available data from the literature is presented to further support our results.

    Central venous catheterization is widely used in neonatal intensive care units to support tiny preterm babies. Pericardial effusion (PCE) and cardiac tamponade are uncommon but potentially fatal complications of percutaneous, umbilical and surgically placed central venous catheters related to intracardiac position or migration. This report describes a case of PCE arising from fluid infused via umbilical venous catheter. The case study highlights two important aspects: one, occurrence of PCE in a baby with satisfactory position of the umbilical catheter, and second, the life-saving application of basic echocardiography by bedside caregivers for the diagnosis and treatment of this critical condition.

    Radioactive chromic phosphate was chosen in place of radioactive gold for control of pleural effusions and ascites. The chromic phosphate has no gamma radiation to complicate the health physics. Its 14.3 day half-life in contrast to that of 2.69 days for gold makes possible the use of much smaller total dosages. There were no untoward results from the use of this material. The results in the series here reported upon compare favorably with those reported for gold198. ImagesFigure 1.Figure 2. PMID:13199706

    Liposarcoma is the name given to a group of soft tissue sarcomas (STSs) with adipocytic differentiation. As a group, liposarcomas are the second most common STSs in adults. In 1951 Kozonis et al published that in the English language only four cases of liposarcomas originating in the mediastinum had been described. Primary mediastinal liposarcoma is an uncommon neoplasm of intrathoracic origin. We present the case of a 47-year-old woman diagnosed with a large mediastinal mass with intrapericardial invasion and massive pericardial effusion; biopsies showed a mediastinal liposarcoma.

Although measuring TTF-1 pleural fluid concentrations was of no value, quantification of napsin A levels allowed the identification of one third of the double-negative stained lung adenocarcinomas, with an overall accuracy similar to classical tumour markers for malignant-benign discrimination (sensitivity 40%, specificity 100%). © 2015 Asian Pacific Society of Respirology.

    Background The diagnosis of malignant mesothelioma is frequently difficult, the most common differential diagnosis being reactive pleural conditions and metastatic adenocarcinoma. Soluble mesothelin levels in serum have recently been shown to be highly specific and moderately sensitive for mesothelioma. As most patients with mesothelioma present with exudative effusions of either the pleura or the peritoneum, a study was undertaken to determine if levels of mesothelin were raised in these fluids and if the increased levels could help to distinguish mesothelioma from other causes of exudative effusion. Methods Pleural fluid was collected from 192 patients who presented to respiratory clinics (52 with malignant mesothelioma, 56 with non‐mesotheliomatous malignancies and 84 with effusions of non‐neoplastic origin). Peritoneal fluid was collected from 42 patients (7 with mesothelioma, 14 with non‐mesotheliomatous malignancies and 21 with benign effusions). Mesothelin levels were determined in effusion and serum samples by ELISA. Results Significantly higher levels of mesothelin were found in effusions of patients with mesothelioma; with a specificity of 98%, the assay had a sensitivity of 67% comparing patients with mesothelioma and those with effusions of non‐neoplastic origin. In 7 out of 10 cases mesothelin levels were raised in the effusion collected 3 weeks to 10 months before the diagnosis of mesothelioma was made; in 4 out of 8 of these, mesothelin levels were increased in the effusion but not in the serum. Conclusions Measurement of mesothelin concentrations in the pleural and/or peritoneal effusion of patients may aid in the differential diagnosis of mesothelioma in patients presenting with effusions.

    To evaluate the effects of otitis media with effusion on surgical parameters, patient safety, perioperative and postoperative complications. Total 890 children who underwent cochlear implantation between 2006 and 2015 were included. The ages ranged from 12 months to 63 months (mean: 32 months). The patients were divided into two groups according to the presence or absence of otitis media with effusion; otitis media with effusion group and non-otitis media group. Of 890 children, 105 had otitis media with effusion prior to surgery. In non-otitis media with group, there were 785 children. The average duration of surgery was 60min (ranged from 28 to 75min) in non-otitis media group, and 90min (ranged from 50 to 135min) in otitis media with effusion group (p<0.05). Granulation tissue and edematous middle ear and mastoid mucosa were observed in all cases of otitis media with effusion during the surgery. There was no significant difference between the complications of groups with or without otitis media with effusion (p>0.05). In 5 of 105 patients, there was a ventilation tube inserted before cochlear implantation, which did not change the outcome of implantation. There is no need for surgical treatment for otitis media with effusion before implantation since otitis media with effusion does not increase the risks associated with cochlear implantation. Operation duration is longer in the presence of otitis media with effusion. However, otitis media with effusion leads to intraoperative difficulties like longer operation duration, bleeding, visualization of the round window membrane, cleansing the middle ear granulations as well as mastoid and petrous air cells.

    OBJECTIVES: To evaluate the effectiveness and safety of pleurodesis carried out entirely on an outpatient basis in patients with recurrent malignant pleural effusions and Karnofsky Performance Status scores ≤70. METHODS: This study was a prospective trial comprising patients with symptomatic recurrent malignant pleural effusion and Karnofsky Performance Status scores ≤70 but >30. All selected patients underwent pleural catheter placement (14 Fr) in an outpatient facility. When chest radiography revealed post‐drainage lung expansion of >90%, pleurodesis (3 g of talc) was performed. Catheters were maintained until the daily output was <100 mL/day. The patients were evaluated in the first month and every three months thereafter for fluid recurrence, the need for additional procedures, and complications. RESULTS: During the study period (January 2005 to July 2007), 64 patients (24 men, 40 women), with an average age of 61.4 years, underwent elective chest tube drainage. Primary sites of the underlying malignancy were breast (27), lung (22), and others (15). Sixty‐six pleural catheters were placed (bilaterally in 2 patients), and 52 talc pleurodesis procedures were performed. Fourteen patients had a trapped lung and were excluded from the trial. No complications were observed during catheter placement or pleurodesis. Post‐pleurodesis complications included catheter obstruction (4 patients) and empyema (1). The average drainage time was 9.9 days. The recurrence rate observed in patients that were alive 30 days after pleurodesis was 13.9% (5/36 patients). Six patients required additional procedures after the pleurodesis. The average survival time was 101 days. CONCLUSION: In this study, talc pleurodesis was safely performed in an outpatient setting with good efficacy and a reasonable complication rate, thereby avoiding hospital admission. PMID:21484035

    The proportions of naïve, memory and effector CD8+ T cells in peripheral blood and pleural effusion from lung adenocarcinoma patients were studied. CD8+ T subsets were identified by using a combination of the following antibodies: anti-CD45RA, anti-CD45RO, anti-CD27 and anti-CD28, as well as antibodies to other markers. Fas-positive cells were determined in each CD8+ T subset. Also, the intracellular cytokine patterns of CD4+ and CD8+ lymphocytes from pleural effusion were analysed. In naïve, memory and effector CD8+ T subsets no significant differences were observed in peripheral blood between healthy donors and cancer patients. In contrast, a high proportion of cells with memory phenotype (CD45RA-CD45RO+CD27+CD28+) and a low proportion of cells with effector phenotype (CD45RA+CD45RO-CD27-CD28-) were found in pleural effusion with respect to peripheral blood (P<0.001). The altered proportions of CD8+ T subsets in pleural effusion were not mediated by type 2 cytokines produced by CD4+ or CD8+ lymphocytes. In the effector CD8+ T subset, from peripheral blood as well as from pleural effusion, a low percentage of perforin-expressing cells was observed compared to granzyme A-expressing cells. Additionally, a high percentage of naïve CD8+ T cells expressing Fas was found. Our data suggest that: (i) terminal-differentiation process of CD8+ T cells is blocked, and (ii) early Fas-expression in CD8+ T cells, which was reflected even in peripheral blood, may lead to apoptosis of naïve cells when they reach the effector stage. All these processes may contribute to the inadequate antitumour immune response found in lung carcinoma patients.

    Purpose The accurate and timely diagnosis of malignant pleural effusion (MPE) in lung cancer patients is important because MPE has a poor prognosis and is classified as stage IV disease. Molecular biomarkers for pleural effusion, such as circulating extracellular microRNAs (miRNAs) isolated from pleural fluid, may help in the diagnosis of MPE. The present study examined whether miRNAs that are deregulated in lung cancer (miR-134, miR-185, and miR-22) can serve as diagnostic markers for lung adenocarcinoma-associated MPE (LA-MPE). Materials and Methods Real-time reverse transcription quantitative polymerase chain reaction was used to measure the expression of the three miRNAs in samples from 87 patients with pleural effusion comprising 45 LA-MPEs and 42 benign pleural effusions (BPEs). The area under the receiver operating characteristic curve (AUC) was then used to evaluate the diagnostic performance of each of the three miRNAs and compare it with that of the common tumor marker, carcinoembryonic antigen (CEA). Results The expression of all three miRNAs was significantly lower in LA-MPE than in BPE (p <0.001). The AUCs for miR-134, miR-185, miR-22, and CEA were 0.721, 0.882, 0.832, and 0.898, respectively. Combining CEA with the three miRNAs increased the diagnostic performance, yielding an AUC of 0.942 (95% confidence interval, 0.864 to 0.982), with a sensitivity of 91.9% and a specificity of 92.5%. Conclusion The present study suggests that the expression levels of circulating extracellular miR-134, miR-185, and miR-22 in patients with pleural effusion may have diagnostic value when differentiating between LA-MPE and BPE.

    ENT surgeons may refer children with otitis media with effusion (OME) to audiology for consideration of hearing aids. They are an option for the treatment of OME, but are only effective if the child actually wears them. Our study investigated what proportion of children referred for hearing aids actually receive them, and whether children use them. Retrospective study of children referred to audiology from November 2013 to August 2014, including 70 children referred by ENT for hearing aids for OME, plus a further 5 children with OME given hearing aids through direct access audiology service. During the study period, there were 202 referrals of children to audiology, of which 70 (34.7%) were for consideration of hearing aids for OME. Of these 70 referred children, 37 (52.9%) were not fitted with hearing aids due to normal audiometry (23), asymptomatic mild hearing loss (7), nonattendance (3), clinical decision to just monitor hearing (1), parental decline (2), and unrecorded reason (1). A total of 38 children (including direct access patients) were fitted with hearing aids for OME. Majority (36/38) of children issued aids used them, 16 all day, 7 only at school, 1 only at home, 3 only when needed, and 9 used them for an unspecified duration; 1 child's use of hearing aids was unrecorded, and 1 child refused to use it. 21 were fitted bilaterally and 17 unilaterally. 37 were behind the ear aids and 1 a BAHA softband. A third of referrals to paediatric audiology by ENT are for consideration of hearing aids for OME. Only about half of children referred to audiology for hearing aids for OME actually receive them, as by the time they see audiology the hearing loss has frequently resolved or is asymptomatic so that aiding is unwarranted. Once fitted, they appear to be well accepted. Hearing aids have fair utilization in children fitted with them for OME. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although tonsilloliths are reported to be fairly common, florid cases casting distinct radiopaque shadows on panoramic radiographs are not often reported. This report illustrates such a case as an incidental finding in an asymptomatic 38-year-old female dental patient. Panoramic radiography revealed distinct radiopaque shadows over the ascending rami of the mandible bilaterally. These radiopacities were localized to the palatine tonsils by computerized tomographic inspection. Tonsillectomy was performed and tonsillolithiasis was confirmed by histopathologic examination.

    In many Asian countries battling with the double burden of increasing noninfectious diseases on top of infectious diseases, multiple myeloma (MM) patients presenting with pleural effusion (PE) pose a great diagnostic challenge. Thus, we aimed to analyze the clinical features and practice patterns of such patients. This is a multicenter retrospective study of newly diagnosed MM patients between January 2011 and December 2015. Among 575 MM patients diagnosed during the study period, 80 (13.9%) that were associated with PE were identified and analyzed. The most common cause of PE was parapneumonic (25%), followed by reactive (18.8%). Higher CRP levels and leukocytosis were indicators of parapneumonic PE. There were 7 (8.8%) with myelomatous PE and 2 (2.5%) with tuberculosis. Fifty-six patients underwent additional examinations to determine the exact cause of effusion; 28 patients received computed tomography (CT) of the chest, 5 patients underwent thoracentesis/biopsy, and 23 patients underwent both CT and thoracentesis/biopsy. On the other hand, 24 patients did not undergo additional analyses but were treated empirically. Real-world analyses of practice patterns in MM patients with PE showed the suboptimal use of invasive procedures to determine the exact cause of PE. Since reversible causes and tuberculosis pleurisy are not uncommon, invasive procedures should be actively incorporated as needed. © 2017 S. Karger AG, Basel.

    Injury to the diaphragm following blunt or penetrating thoracoabdominal trauma is not uncommon. Recognition of this important complication of trauma continues to be a challenge because of the lack of specific clinical and plain radiographic features, the frequent presence of other serious injuries and the potential for delayed presentation. Delayed diaphragmatic herniation often presents with catastrophic bowel obstruction or strangulation. Early recognition of diaphragmatic injury is required to avoid this potentially lethal complication. The case of a 35-year-old man with a history of a knife wound to the left flank 15 years previously, who presented with unexplained acute hypoxemic respiratory failure and a unilateral exudative pleural effusion that was refractory to tube thoracostomy drainage, is reported. After admission to hospital, he developed gross dilation of his colon; emergency laparotomy revealed an incarcerated colonic herniation into the left hemithorax. Interesting clinical features of this patient's case included the patient's hobby of weightlifting, a persistently deviated mediastinum despite drainage of the pleural effusion and deceptive pleural fluid biochemical indices.

    Our purpose was to assess the efficacy, permanence and safety of thoracoscopic talc poudrage (TTP) for pleurodesis in malignant effusions. We report the follow-up of 360 patients who received TTP in two centers in Marseille (France). Eighty-eight patients presented with mesothelioma and 272 had pleural metastasis. The mean follow-up time was 12 months (range: 2-120). Out of the 327 patients whose response could be evaluated, 90.2% had a successful pleurodesis at 1 month, and 82.1% had a life-long pleural symphysis. Adverse effects included one death 3 days after the procedure in an end-stage patient, fever (9.8%), infection of the parietal scar (2.5%) and pulmonary infection (0.8%). TTP is an effective and safe method of life-long pleurodesis. It should be performed early on in the history of malignant effusions to avoid failures of the technic, mainly linked to trapped lung and to the general condition of patients.

    Malignant pleural effusion (MPE) occurs at a terminal stage of cancer, and related symptoms may considerably reduce a patient's respiratory function and quality of life. We assessed the benefit of simple intrapleural hyperthermia (SIH) during thoracoscopic exploration for MPE. We conducted a retrospective review of 34 patients underwent thoracoscopic exploration and SIH procedures for MPE between April, 2009 and July, 2014 at our institution. One month after removal of the tube, therapeutic efficacy was evaluated, calculating response rates and recurrence rate. In this cohort (male, 11; female, 23; average age, 54.2 ± 12.7 years), the most frequent primary cancers were breast (n = 11, 32.4 %), lung (n = 10, 29.4 %), and ovarian (n = 6, 17.6 %). Therapeutic response (ie, presence of pleural effusion) was assessed 1 month after chest tube removal, with 19 (55.9 %) showing complete response (CR), 9 (26.5 %) showing partial response (PR), and non-response (NR) seen in 6 (17.6 %). The combined (CR + PR) response rate was 82.4 %. During follow-up, there were seven instances of recurrence, requiring repeat drainage. Three- and 7-month recurrence-free rates were 86.9 and 73.9 %, respectively. No postoperative respiratory complications or fever developed. Early death within 3 months from progression of primary cancer was identified as a risk factor in patients of NR status (HR = 18.36, p = 0.043). If thoracoscopic exploration is indicated for MPE, SIH is a safe and effective management alternative in patients whose primary malignancy is not rapidly progressing.

    Mesothelioma is a form of cancer generally caused from previous exposure to asbestos. Although it was considered a rare neoplasm in the past, its incidence is increasing worldwide due to extensive use of asbestos. In the current practice of medicine, the gold standard for diagnosing mesothelioma is through a pleural biopsy with subsequent histologic examination of the tissue. The diagnostic tissue should demonstrate the invasion by the tumor and is obtained through thoracoscopy or open thoracotomy, both being highly invasive surgical operations. On the other hand, thoracocentesis, which is removal of effusion fluid from the pleural space, is a far less invasive procedure that can provide material for cytological examination. In this study, we aim at detecting and classifying malignant mesothelioma based on the nuclear chromatin distribution from digital images of mesothelial cells in effusion cytology specimens. Accordingly, a computerized method is developed to determine whether a set of nuclei belonging to a patient is benign or malignant. The quantification of chromatin distribution is performed by using the optimal transport-based linear embedding for segmented nuclei in combination with the modified Fisher discriminant analysis. Classification is then performed through a k-nearest neighborhood approach and a basic voting strategy. Our experiments on 34 different human cases result in 100% accurate predictions computed with blind cross validation. Experimental comparisons also show that the new method can significantly outperform standard numerical feature-type methods in terms of agreement with the clinical diagnosis gold standard. According to our results, we conclude that nuclear structure of mesothelial cells alone may contain enough information to separate malignant mesothelioma from benign mesothelial proliferations. © 2015 International Society for Advancement of Cytometry.

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

    In an effort to examine the rules by which information of bilaterally applied bone-conducted signals arising from interaural time differences (ITD) and interaural intensity differences (IID) is combined, data were measured for continuous 500 Hz narrow band noise at 65-70 dB HL in 11 patients with bilateral congenital aural atresia. Time-intensity trading functions were obtained by shifting the sound image towards one side using ITD, and shifting back to a centered sound image by varying the IID in the same ear (auditory midline task). ITD values were varied from -600 to +600 micros at 200 micros steps, where negative values indicate delays to the right ear. The results indicate that time-intensity trading is present in patients with bilateral aural atresia. The gross response properties of time-intensity trading in response to bone-conducted signals were comparable in patients with bilateral aural atresia and normal-hearing subjects, though there was a larger inter-subject variability and higher discrimination thresholds across IIDs in the atresia group. These results suggest that the mature auditory brainstem has a potential to employ binaural cues later in life, although to a restricted degree. A binaural fitting of a bone-conducted hearing aid might optimize binaural hearing and improve sound lateralization, and we recommend now systematically bilateral fitting in aural atresia patients.

    Laterality in temporal lobe epilepsy is usually defined by EEG and imaging results. We investigated whether the analysis of seizure semiology including lateralizing seizure phenomena identifies bilateral independent temporal lobe seizure onset. We investigated the seizure semiology in 17 patients in whom invasive EEG-video-monitoring documented bilateral temporal seizure onset. The results were compared to 20 left and 20 right consecutive temporal lobe epilepsy (TLE) patients who were seizure free after anterior temporal lobe resection. The seizure semiology was analyzed using the semiological seizure classification with particular emphasis on the sequence of seizure phenomena over time and lateralizing seizure phenomena. Statistical analysis included chi-square test or Fisher's exact test. Bitemporal lobe epilepsy patients had more frequently different seizure semiology (100% vs. 40%; p<0.001) and significantly more often lateralizing seizure phenomena pointing to bilateral seizure onset compared to patients with unilateral TLE (67% vs. 11%; p<0.001). The sensitivity of identical vs. different seizure semiology for the identification of bilateral TLE was high (100%) with a specificity of 60%. Lateralizing seizure phenomena had a low sensitivity (59%) but a high specificity (89%). The combination of lateralizing seizure phenomena and different seizure semiology showed a high specificity (94%) but a low sensitivity (59%). The analysis of seizure semiology including lateralizing seizure phenomena adds important clinical information to identify patients with bilateral TLE. Copyright © 2014 Elsevier B.V.

    The objective of this study was to evaluate the age distribution, mode of injury, type of hematomas, and their surgical outcome in patients with bilateral traumatic head injuries. The present study included 669 cases of traumatic head injury who presented at the neurosurgery emergency out of which 94 cases had bilateral head injuries from the period of August 2009 to April 2014. The data from the hospital computerized database were retrospectively analysed. Cases of bilateral traumatic head injury included 94 patients out of which 88.29 % (n = 83) were males and 11.70 % (n = 11) were females. Commonest mode of injury was road traffic accident in 56.38 % (n = 53) followed by fall from height in 29.78 % (n = 28). In our study, 25.53 % patients had epidural hematoma (EDH) with intracerebral hematoma (ICH) or contusion (n = 24), followed by EDH with subarachnoid hemorrhage (SAH) in 18.08 % (n = 17). At the time of discharge, all those patients managed conservatively had good Glasgow outcome scale (GOS) while with surgical intervention 58 % patients had good GOS, 19 % had moderate disability, and 9 % remained with severe disability. In cases of bilateral hematomas, EDH is most common and should be managed in neurosurgical emergency. Other combinations of bilateral intracranial hematomas should be managed according to the surgical indication and serial CT imaging.

    A seven-year-old, 41 kg, intact, cross breed dog, was presented with a history of bilateral hind limb lameness after falling from a height of 1 m. Clinical and radiographic findings were consistent with bilateral patellar tendon rupture. Surgical repair was performed bilaterally. The tendons were sutured primarily, and an internal splint of nylon leader was added. Good apposition of the severed tendon ends had been achieved intraoperatively; however, post operative radiographs showed supra-trochlear displacement of both patellae. The casts used to immobilize the stifle joints slipped distally and three days post operatively the tendon repair had broken down, bilaterally. Revision surgery was undertaken and the tendons were re-sutured. Nylon leader was placed through holes that had been drilled in the patellae and tibiae. The stifle joints were immobilized with type I external skeletal fixators (ESFs). Both freeform polymethylmethacrylate (PMMA) connecting bars were found to be broken at the level of the stifle joints two days later, without any disruption of the primary tendon repair. Each connecting bar was replaced with two connecting bars of PMMA reinforced with 3 mm steel wire. The dog was fully weight-bearing with a reduced range of motion in flexion immediately after removal of the ESFs at six weeks and was still sound 18 months post-operatively. Primary tendon repair in combination with adequate immobilization allowed for an excellent outcome in a complicated bilateral pathology.

    We investigated the effects of increased inter-hemispheric interaction (IHI) on five creativity dimensions (appropriateness, detail, categorical distinctiveness, fluency, and originality) of the Alternate Uses Task. Two methods were used to indicate degree of IHI. Trait IHI was indicated by individual differences in handedness, mixed-handers showing greater IHI than strong-handers. State IHI was directly manipulated by central (control group) and bilateral viewing conditions of a 30 s eye movement task (EM). Results indicate significantly higher creativity for mixed-handers, as compared to strong-handers, for all five sub-scores separately and linearly combined. Bilateral EM increased originality and categorical distinctiveness (i.e., flexibility) of strong-handers, but had no effect on mixed-handers. Strong-handers in the bilateral EM group were not different from mixed-handers. Additionally, the bilateral EM effect on strong-handers had different durations for originality (up to 7-9 min) and categorical distinctiveness (up to 3 min). The results suggest that greater IHI can facilitate creativity of strong-handers, but that the characteristically higher IHI of mixed-handers was unaffected by the bilateral EM manipulation.

    An inner ear test battery may suggest bilateral involvement and aid in 'grading' of potential disease in a patient with actively symptomatic Meniere's disease (MD). This study applied an inner ear test battery in patients with bilateral MD to map the inner ear deficits in each ear. From 2009 to 2012, 100 (20%) of 498 MD patients were diagnosed with bilateral involvement, which was defined as established MD in one ear, and the opposite ear had inner ear symptoms combined with documented hearing loss. Each patient underwent audiometry, and ocular vestibular-evoked myogenic potential (oVEMP), cervical VEMP (cVEMP), and caloric tests. Grading of inner ear deficits was based on the number of abnormal results in the inner ear test battery. Of 100 patients with bilateral MD, 54% had the same grade and 46% had different grades in their 2 ears. On the other hand, based on four-tone average, 79% had the same Meniere stage and 21% had different stages in their two ears. The difference between ears with asymmetric grades (46%) and ears with asymmetric stages (21%) accounts for 25% of bilateral MD patients, which may be caused by the saccular hydrops in the opposite ear.

    Abstract We investigated the role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) for the differential diagnosis of malignant and benign pleural effusion. We studied 36 consecutive patients with histologically proven cancer (excluding malignant mesothelioma) who underwent FDG-PET/CT for suspected malignant pleural effusion. Fourteen patients had cytologically proven malignant pleural effusion and the other 22 patients had either negative cytology or clinical follow-up, which confirmed the benign etiology. We examined the maximum standardized uptake values (SUVmax) of pleural effusion and the target-to-normal tissue ratio (TNR), calculated as the ratio of the pleural effusion SUVmax to the SUVmean of the normal tissues (liver, spleen, 12th thoracic vertebrae [Th12], thoracic aorta, and spinalis muscle). We also examined the size and density (in Hounsfield units) of the pleural effusion and pleural abnormalities on CT images. TNR (Th12) and increased pleural FDG uptake compared to background blood pool were significantly more frequent in cases with malignant pleural effusion (P < 0.05 for both). The cutoff TNR (Th12) value of >0.95 was the most accurate; the sensitivity, specificity, and accuracy for this value were 93%, 68%, and 75%, respectively. FDG-PET/CT can be a useful method for the differential diagnosis of malignant and benign pleural effusion. PMID:26200610

    Pleural effusion is a common diagnostic dilemma for the pulmonologist. A histological diagnosis would many a time steer the way to an accurate diagnosis of the aetiologies of pleural effusions. This study has compared two methods for obtaining histological specimens in cases of undiagnosed pleural effusions. To compare the efficacy of closed pleural biopsy with Abrahm's needle and medical thoracoscopic biopsy in the diagnosis of undiagnosed exudative pleural effusions at a tertiary care setting. Randomized controlled study. November 2008-October 2010. All patients who were admitted with pleural effusions underwent a clinical workup for pleural effusions. Light's criterion was used to differentiate between exudative and transudative pleural effusions. Those patients with exudative pleural effusions, who did not have a specific diagnosis, were included in the study. Fifty eight patients were included in the study and they were randomized into 2 Groups of 29 patients each. One group was subjected to medical thoracoscopic pleural biopsy and the other to closed pleural biopsy with Abrahm's needle. Demographic, clinical and biochemical characteristics, diagnostic yields and the complications among the two groups were compared. Medical thoracoscopy has a diagnostic yield of 86.2% with complication rate of 10.3% compared to 62.1% and 17.2% respectively in closed pleural biopsy group. Medical thoracoscopic pleural biopsy had a better diagnostic yield with a lower complication rate as compared to closed pleural biopsy with Abrahm's needle.

    Kaposi's sarcoma (KS) and tuberculosis (TB) commonly cause pleural effusions in high human immunodeficiency virus (HIV) burden resource-limited countries. Differentiating between them is challenging, as pleural biopsy and TB culture are rarely available. To identify markers to differentiate between TB effusions and KS effusions in HIV-positive patients, and to compare liquid culture and Xpert MTB/RIF in pleural fluid. Fifty HIV-positive patients with pleural effusions recruited in Malawi underwent pleural ultrasound and aspiration. Fluid visual inspection, cell count, bacterial culture, glucose/protein, solid and liquid TB culture and Xpert were performed. The mean age of the patients was 32 years; 30/50 (60%) were male and 29 (58%) had cutaneous/oral KS. Thirteen (26%) pleural fluid samples were liquid culture-positive for TB, while 9/13 (69%) were Xpert-positive. Three (10.3%) KS patients had culture-positive TB effusions; 17 (58.6%) had KS effusions. The relative risk of TB in KS patients increased with limited KS, loculated fluid and low glucose. Eleven (52.3%) non-KS patients had culture-positive TB effusions associated with male sex, straw-coloured fluid and fibrin stranding on ultrasound. KS patients were most likely to have KS effusion, but TB should be considered. Most non-KS patients had TB, supporting the use of World Health Organization guidelines. Xpert identified two thirds of liquid culture-positive results.

    This study investigated the serum vascular endothelial growth factor (VEGF) levels in children with community-acquired pneumonia. Serum VEGF levels were measured in patients with pneumonia (n=29) and in control subjects (n=27) by a sandwich enzyme-linked immunosorbent assay. The pneumonia group was classified into bronchopneumonia with pleural effusion (n=1), bronchopneumonia without pleural effusion (n=15), lobar pneumonia with pleural effusion (n=4), and lobar pneumonia without pleural effusion (n=9) groups based on the findings of chest radiographs. We also measured serum IL-6 levels and the other acute inflammatory parameters. Serum levels of VEGF in children with pneumonia were significantly higher than those in control subjects (p<0.01). Children with lobar pneumonia with or without effusion showed significantly higher levels of serum VEGF than children with bronchopneumonia. For lobar pneumonia, children with pleural effusion showed higher levels of VEGF than those without pleural effusion. Children with a positive urinary S. pneumonia antigen test also showed higher levels of VEGF than those with a negative result. Serum IL-6 levels did not show significant differences between children with pneumonia and control subjects. Serum levels of VEGF showed a positive correlation with the erythrocyte sedimentation rate in the children with pneumonia. In conclusion, VEGF may be one of the key mediators that lead to lobar pneumonia and parapneumonic effusion.

    The purpose of this study was to determine whether or not pleural effusion could be a cause of round atelectasis of the lung. The study group consists of 20 patients with round atelectasis who had no evidence of asbestos exposure, who had normal baseline chest radiographs that showed no evidence of preexisting pleural or pulmonary disease, and who developed pleural effusion from a variety of causes. Chest radiographs were examined for signs of round atelectasis at the time of initial presentation of the pleural effusion. Follow-up radiographs, spanning a period of 1 month to 4 years after resolution of the pleural effusion, were also examined in all 20 cases. Round atelectasis was seen initially as a rounded mass-like opacity that produced a focal, upward bulge in the curvilinear meniscus of pleural effusion in 17 cases. In three cases round atelectasis was seen initially as a spherical mass with a comet-tail sign located slightly above the pleural effusion. As the pleural effusion resolved, typical findings of round atelectasis developed in all 20 cases. Pleural effusion, in the absence of exposure to asbestos, can cause round atelectasis.

    High-resolution proton nuclear magnetic resonance (NMR) spectrometry of biofluids has been increasingly used in laboratory diagnosis of various diseases. In this study, we extended the use of (1)H NMR spectroscopy for laboratory diagnosis of exudative pleural effusions using pleural fluids. We compared this new NMR-based test with Light's criteria, the current gold standard for laboratory diagnosis of exudative pleural effusions. We analyzed 67 samples of pleural effusions from patients with pulmonary malignancy (N = 32), pulmonary tuberculosis (N = 18), and congestive heart failure (N = 17). The metabolomes of pleural effusions were analyzed using (1)H NMR spectroscopy on a Bruker 600 MHz spectrometer. Through a metabolome-wide association approach with filtering of insignificant markers (p value <4 × 10(-6)) and multivariate analysis (principal component analysis and orthogonal partial least squares-discriminant analysis), lipoprotein was found to be the best biomarker that distinguished exudates from transudates. Using NMR-based lipoprotein profiling to classify exudative pleural effusions from transudates, the area-under-receiver operating characteristic (ROC) curve was 0.96 with sensitivity of 98%, specificity of 88%, and accuracy of 98%. In contrast, the current gold standard, Light's criteria, give a specificity of only 65% at the same sensitivity level of 98%. Using the principle of size exclusion, NMR-based lipoprotein profiling of pleural fluids has an unprecedented diagnostic performance superiority over the Light's criteria. The capillary leaks secondary to inflammation result in a larger pleural pore-size, which allows the large-sized lipoproteins to accumulate in exudative pleural effusions. In contrast, the pleural permeability is intact in transudates, which allow only small-sized lipoproteins to pass into the pleural effusions. The average capillary pore-size of the pleura can therefore be determined by using NMR-based lipoprotein profiling of

    We report the case of a terminally ill cancer patient with recurrent pericardial and bilateral pleural effusions who was scheduled for video-assisted thoracoscopic surgery. The operation was performed with the patient awake under epidural anaesthesia. The patient's cough reflex in response to lung manipulation was successfully minimised by the inhalation of aerosolised lidocaine. Video-assisted thoracic surgery requires the exclusion of a lung from ventilation. In order to support one-lung spontaneous ventilation in this high-risk patient, we successfully used non-invasive bilevel positive airway pressure ventilation via a facemask. Based on this preliminary experience, we think that critically ill patients scheduled for palliative surgery can be successfully managed with the combination of minimally invasive surgical techniques and neuraxial block with non-invasive lung ventilation.

    To determine the incidence of bilateral distal biceps tendon ruptures. A retrospective review of 321 patients who underwent operative repair of a distal biceps tendon rupture between 1988 and 2010 identified 26 patients with bilateral ruptures. We recorded patient age, mechanism of injury, time between symptom onset before the first surgery and subsequent contralateral symptoms, and time between surgeries. Twenty-two bilateral ruptures were confirmed intra-operatively, 3 by MRI, and 1 was lost to follow up. A total of 23 bilateral ruptures (92%) occurred in men. The average age at the initial rupture was 44 years (range, 29-74 y). The average age at subsequent rupture was 48 years (range, 36-79 y). Excluding the 2 women (age 72 and 79 y), the average age at the initial rupture was 42 years and the average age at subsequent rupture was 46 years. The average interval between ruptures was 4.1 years (range, 0.8-13.9 y). The initial rupture occurred in the dominant extremity in 12 cases (50%) and in the nondominant extremity in 10 cases (42%); in 3 patients (8%) the dominance was not documented or ambidextrous. Thirty-three percent were heavy laborers, 3 patients had a smoking history, and 1 patient reported a history of steroid use. Twenty-two patients (88%) had the second side repaired, where we noted that 12 (55%) of the second tendon ruptures were partial tears. The 8% cumulative incidence of bilateral biceps tendon ruptures in a consecutive series of biceps tendon repairs may be higher because not all patients were contacted, which introduced a sampling bias. This 8% rate is markedly higher than the reported rate of 1.2 per 100,000 for an isolated distal biceps tendon rupture. This implies that patients with a distal biceps tendon rupture are at risk for a rupture on the contralateral side. Prognostic III. Copyright © 2012 American Society for Surgery of the Hand.

    Filariasis presenting with pericardial effusion with tamponade is rare. We report a case of a 30-year-old female who was admitted with severe dyspnea and chest pain since 2 days. Echocardiogram showed massive pericardial effusion with tamponade. Pericardial fluid aspiration drained 1.2 L of hemorrhagic fluid. Cytology examination revealed microfilaria of Wuchereria bancrofti. She was treated with diethyl carbamazine and discharged. Six weeks later, she presented again with massive pericardial effusion with cardiac tamponade. Pericardiocentesis was done. Cytology examination revealed microfilaria of W. bancrofti. This time she was treated with ivermectin and albendazole and cured. Hemorrhagic effusion resolved completely. Though relatively uncommon, tropical diseases must always be considered in the etiological diagnosis of recurrent pericardial effusion.

    Subdural effusions following decompressive craniotomy for trauma are usually benign, ipsilateral to the craniotomy and resolve spontaneously. Far less common and more dangerous are contralateral subdural effusions causing external cerebral herniation. We report a case of recurrent contralateral effusion and highlight the management dilemmas. Arachnoid tear is probably the cause of these collections. Contralateral subdural effusions should be suspected in patients who have delayed neurological deterioration after an initial improvement particularly in the setting of increased "flap bulge" though they may also be found in patients who remain moribund after initial surgery. There are no clear-cut guidelines on their management due to their rarity. A variety of options like subduro-peritoneal shunt and drainage with simultaneous cranioplasty may be tried. In situations where resources or patient compliance is an issue, tapping the effusion followed by cranial strapping may be tried as was done in our case.

    Pleural effusion samples were obtained from 55 patients with malignant disease, including patients with primary lung cancers and those with a variety of other tumours metastatic to the pleura. The effusions were assayed for the presence of hepatocyte growth factor/scatter factor (HGF/SF), by both ELISA and bioassay. The presence of malignant cells in the effusions was also assessed. Detectable amounts of the factor, as judged by both criteria, were found in over 90% of all the effusions, including those from patients with a wide variety of carcinomas and also lymphomas. A wide range of HGF/SF levels were found for all tumour classes, some effusions containing high levels above 4 ng ml-1. It is concluded that tumours within the pleura and adjacent lung tissue are usually exposed to biologically significant levels of HGF/SF. PMID:8562345

    Otitis media with effusion and obesity are both common in childhood and might share some immunological alterations. This study aimed to investigate the relationship between chronic otitis media with effusion and childhood overweight or obesity, including the potential effects of adenoid or tonsillar hypertrophy on that relationship. This study included 60 children with chronic otitis media with effusion and 86 healthy children aged from 2 to 10 years. Measures of height and weight were used to calculate the body mass index, weight for height and weight z score. The prevalence of overweight or obesity was higher in children with chronic otitis media with effusion, according to the weight for height percentiles (p = 0.012). However, neither the presence of adenoid or tonsillar hypertrophy nor the degree of adenoid hypertrophy was associated with overweight or obesity. Overweight and obesity might be risk factors for developing chronic otitis media with effusion, or vice versa.

    Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine. PMID:26295001

    Purpose. The aim of this study was to evaluate the sensitivity of pleural C-reactive protein (CRP) biomarker levels in identifying parapneumonic effusions. Methods. A single-center, retrospective review of 244 patients diagnosed with pleural effusions was initiated among patients at the Rabin Medical Center, Petah Tikva, Israel, between January 2011 and December 2013. The patients were categorized into 4 groups according to their type of pleural effusion as follows: heart failure, malignant, post-lung transplantation, and parapneumonic effusion. Results. The pleural CRP levels significantly differentiated the four groups (p < 0.001) with the following means: parapneumonic effusion, 5.38 ± 4.85 mg/dL; lung transplant, 2.77 ± 2.66 mg/dL; malignancy, 1.19 ± 1.51 mg/dL; and heart failure, 0.57 ± 0.81 mg/dL. The pleural fluid CRP cut-off value for differentiating among parapneumonic effusions and the other 3 groups was 1.38 mg/dL. The sensitivity, specificity, positive predictive value, and negative predictive value were 84.2%, 71.5%, 37%, and 95%, respectively. A backward logistic regression model selected CRP as the single predictor of parapneumonic effusion (OR = 1.59, 95% CI = 1.37-1.89). Conclusions. Pleural fluid CRP levels can be used to distinguish between parapneumonic effusions and other types of exudative effusions. CRP levels < 0.64 mg/dL are likely to indicate a pleural effusion from congestive heart failure, whereas levels ≥ 1.38 mg/dL are suggestive of an infectious etiology.

    Once the malignant pleural or peritoneal effusion is developed it is difficult to control. This report presents a new method for controlling the malignant effusions. Forty-eight patients, 29 males and 19 females with an average age of 61.2 years old, who were satisfied with the study inclusion criteria, were recruited in this study. Twenty-seven and 21 patients had a malignant pleural and peritoneal effusion, respectively. After draining most of fluids, these patients received intra-cavity infusion of rAd-p53 once per week for 4 weeks, at dose of 2×10¹² viral particles (VP) diluted into 200 mL of saline solution for pleural effusions, and 4×10¹² VP diluted into 500 mL of saline solution for peritoneal effusions. Participants were followed up for a median time of 13.6 month. A total of 11 cases, 7 with pleural effusions and 4 with peritoneal effusions achieved a complete response (CR), and 20 cases (12 pleural effusions and 8 peritoneal effusions) had a partial response (PR). The overall response rate is 64.6%. Patients' quality of life, assessed by using Karnofsky performance scale (KPS) scores, was improved by an average of 26.4. The one-year of overall survival rate was 54.2% with a median survival time of 12.5 months. There were no serious side effects observed except for self-limited fever found in 79.8% of the cases. Intra-cavity infusion of rAd-p53 is an effective and safe treatment for the patients with malignant pleural or peritoneal effusions, especially for those patients who can't tolerate the standard treatments.

    Conclusion The expression profile of matrix metalloproteinases (MMP) and tissue inhibitor of metalloproteinase-2 (TIMP-2) was specific to the type of middle ear effusion. Further studies are necessary for elucidating its correlation with the sequelae of otitis media with effusion (OME) and idiopathic hemotympanum. Objectives We aimed to investigate the relative activities of gelatinases (MMP-2 and 9), stromelysin-1 (MMP-3), matrilysin-1 (MMP-7) as well as measuring TIMP-2 levels in the serous and mucous effusions of OME and hemorrhagic effusion of the idiopathic hemotympanum. Method Middle ear effusions were collected from patients with OME and idiopathic hemotympanum, and were classified as mucoid, serous or hemorrhagic. MMP activity in the effusion samples was examined by gelatin and casein zymography. Levels of TIMP-2 were measured by ELISA. Human temporal bones sections, with and without otitis media (OM), were examined histologically. Results One case showed tympanic membrane thinning in the OM group, but none in the control group. While MMP-2 was present in all effusions, the active form of MMP-2 was found only in mucous effusions. MMP-3 and MMP-7 activity was detected only in the mucous effusions. MMP-9 exhibited activity in all effusions, with the highest levels in mucous effusions. TIMP-2 levels were markedly elevated in serous effusions. PMID:17851959

  1. [Origin of bilateral-symmetrical animals (Bilateria)].

    PubMed

    Malakhov, V V

    2004-01-01

    The paper is an attempt to attack the old problem of the origin of Bilateria by the methods of evolutionary tetrad (i.e. combination of comparative anatomy, comparative embryology, paleontology, and molecular biology). Three groups of theories of classical comparative anatomy (planulod-turbellarian, archicoelomate, and metameric) are discussed. Comparative embryology brings out clearly that the ventral side of embryo comes from the blastoporal region in all groups of Bilateria (except Chordata, where the blastoporal region corresponds to the dorsal side that is come out of the upside-down morphology of chordates) and mouth and anus comes from the anterior and posterior ends of elongated blastopore. From the point of view of paleontology, some of vendian metazoans demonstrate transitional conditions between the Radiata and Bilateria. Vendian bilaterians are metameric organisms with normal or asymmetric position of segments and could be pictured as "bilateral coelenterates" creeping on the oral surface. In Cnidaria, the expression of homologues of "Brachyury", "goosecoid", and "fork head" genes are revealed in the circular region around the mouth. In Bilateria, these genes are expressed along the elongated blastopore and around the mouth and anus. These results support the old conception on the amphistomic origin of mouth and anus as well as the homology between the oral disc of cnidarians and ventral side of Bilateria. The combination of four mentioned approaches enables us to propose the conception of the origin of Bilateria from vendian bilateral coelenterates with numerous metameric pouches of gastral cavity. Bilaterian ancestors crawled on the oral disc (= ventral side). These ancestors gave rise to both phanerosoic cnidarians and triploblastic bilaterians. Cnidarian ancestors attached to bottom by the aboral pole with the resulting degradation of aboral nerve ganglion. Bilateral symmetry of anthozoans is considered to be primitive feature for cnidarians. In

    Rats were sacrificed 2 months after a single dose of 10-30 Gy of /sup 60/Co gamma rays delivered to either a right unilateral or a bilateral thoracic port. Four indices of lung endothelial function were measured: the activities of angiotensin-converting enzyme (ACE) and plasminogen activator (PLA) and the production of prostacyclin (PGI2) and thromboxane (TXA2). The number of macrophages recovered by bronchoalveolar lavage (BAL) and the degree of right ventricular hypertrophy (an index of pulmonary hypertension) also were determined. Right lung ACE and PLA activity decreased linearly, and PGI2 and TXA2 production increased linearly with increasing radiation dose. The response curves for right unilateral and bilateral thoracic irradiation were not significantly different. In contrast, bilateral irradiation was more toxic than unilateral, since rats exposed to the former exhibited decreased body weight, an increased incidence of pleural effusions, an increase in the number of macrophages recovered by BAL, and right ventricular hypertrophy. These data demonstrate that pulmonary endothelial dysfunction induced by hemithorax irradiation represents a direct response of the endothelium to radiation injury and is not secondary to other phenomena such as shunting of function to the shielded lung.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    To report surgical management bilateral lateral patellar luxation in a mature alpaca using a combination of trochlear wedge recession (TWR), tibial tuberosity transposition (TTT), and joint capsule imbrication. Clinical case report. 9-year-old castrated male Alpaca. Bilateral, grade III/IV, lateral patellar luxation was identified by palpation, lameness examination and confirmed with radiography and ultrasonography. Surgical procedures were staged, with the left stifle treated first. Bilateral TWR, TTT, and joint capsule imbrication were performed. Outcome was assessed by radiography and follow up lameness examinations. An immediate improvement in weight bearing occurred after surgery of the left hind limb. Five months after initial surgery, right hind limb patella luxation was corrected. After surgery on the 2nd limb, the alpaca had progressive improvement in weight bearing during hospitalization. At 12 months, there were no signs of lameness and the alpaca had resumed normal activities. For bilateral lateral patellar luxation, a combination of TWR, TTT, and joint capsule imbrication resulted in excellent long-term outcome. © Copyright 2014 by The American College of Veterinary Surgeons.

    Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM) too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it's management both at the time of cleft lip repair and also secondarily

    Talon cusp is an uncommon condition often present in the maxillary incisors and mandibular premolars. Morphologically, this anomaly has a well-delineated cusp that extends at least half the distance from the cementoenamel junction or cingulum area to the incisal edge. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. Presented is a case of bilateral bifid talon cusp in maxillary central incisors that was successfully managed with conservative therapy.

    Isolated submandibular swellings pose a diagnostic challenge to the practising otolaryngologist. We report an unusual case of mumps isolated to bilateral submandibular glands. We discuss the case and the literature surrounding this condition and remind clinicians that mumps should be considered as a diagnosis in the presence of submandibular gland swelling in the absence of typical parotid swelling associated with mumps. Early consideration of this differential diagnosis, serological testing and a multidisciplinary approach may help to clinch the diagnosis earlier and prevent spread of the virus. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Inguinal hernias are rare in females. The authors report a case of bilateral inguinal hernias in a 10-year-old female. On exploration, the patient was found to be having a sliding hernia containing incarcerated ovary as contents on both sides. Peroperatively the contents were reduced, the sac was transfixed at its base and the redundant sac was excised. The repair of this form of hernias is more difficult because of adhesions between the contents and the wall of the sac and risk of damage during dissection. A description of this clinical presentation in the pre operative assessment and operative management are discussed in this report. PMID:25918632

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

Her urinary pregnancy test was positive. Initial transvaginal ultrasound demonstrated an irregular complex structure with a fluid filled centre in the right adnexum. Despite the diagnosis of a possible underlying unruptured right tubal ectopic pregnancy, she declined surgical intervention and was managed expectantly as an inpatient. When she complained of increasing abdominal pain with haemodynamic instability, an emergency laparotomy was performed and a diagnosis of bilateral tubal ectopic pregnancy was made.

Two robots electronically coupled so slave robot moves in response to commands from master robot. Teleoperation greatly enhanced if forces acting on slave robot fed back to operator, giving operator feeling he or she manipulates remote environment directly. Main advantage of bilateral impedance control: enables arbitrary specification of desired performance characteristics for telemanipulator system. Relationship between force and position modulated at both ends of system to suit requirements of task.

    The cytological examination of peri-prosthetic breast effusions allowed the diagnosis of bilateral breast-implant ALK-negative anaplastic large cell lymphoma (BI-ALCL) in the case reported. Ten years after reconstructive surgery with bilateral breast implants, a large unilateral seroma developed and was cytologically analyzed. The presence of CD30 and CD4-positive large-sized atypical lymphoid cells exhibiting horseshoe-shaped nuclei and a brisk mitotic activity rendered the diagnosis of BI-ALCL. Similar cells were seen in the peri-prosthetic fluid intraoperatively collected from the contralateral breast. Although initial histological analysis of the capsulectomy specimens showed unilateral tumor, the cytological findings prompted a more thorough tissue sampling, resulting in the diagnosis of bilateral disease. BI-ALCL usually follows an indolent clinical course; however, there are reported cases with an aggressive behavior. While the presence of bilateral disease is a putative risk factor for a bad prognosis, the small number of cases reported precludes a definitive assessment of this risk. Since most BI-ALCL present with late seromas, cytologic analysis of these effusions in women with breast implants should be mandatory. Cytology is a safe tool for diagnosis and follow-up of patients with breast implant-related late seromas, sometimes proven more sensitive than histological analysis. Complete bilateral capsulectomy and a detailed histological analysis should follow a cytological diagnosis of BI-ALCL in a breast effusion in order to avoid false negative diagnoses. Our case constitutes the first published report of a bilateral BI-ALCL diagnosed by cytology. Diagn. Cytopathol. 2016;44:623-627. © 2016 Wiley Periodicals, Inc.

    Fully stabilised zirconia (FSZ) samples have been implanted with helium-ions of different energies (200 keV and 1 MeV) and with different fluences (1.4×10 13-1.4×10 16 He +/cm 2). Neutron depth profiling (NDP) for different annealing temperatures and effusion experiments in two different experimental systems with different thermal annealings have been performed on these samples. The samples were analysed by electron microscopy during the various annealing stages. For the low-fluence samples, the diffusion of helium is probably caused by vacancy assisted interstitial diffusion with an activation energy of 1.6 eV. In the highest fluence samples probably high pressure bubbles are formed during thermal annealing.

The most common associated factors were alcoholism, previous pneumonia and diabetes. Other bacteria were identified as Enterobacter aerogenes, Bacteroides and Prevotella intermedia capillosus in two patients. The mean duration of antibiotic therapy was 28 days; six patients underwent pleural drainage by chest tube and one patient needed surgery due to poor clinical progress. The mean duration of hospitalization was 30 days with satisfactory outcome in all cases, despite some changes in residual function. Copyright © 2013 SEPAR. Published by Elsevier Espana.

    The vaporization of CuBr{sub 2} and CuBr was studied by a torsion effusion apparatus. The CuBr{sub 2} in a first step decomposes according to the reaction: (1) 2CuBr{sub 2}(s) {yields} 2{alpha}CuBr(s) + Br{sub 2}(g), whereas CuBr vaporizes at higher temperature according to the predominant reaction: (2) 3CuBr(s) {yields} Cu{sub 3}Br{sub 3}(g). From the measured vapor pressures, the standard enthalpies of both reactions were obtained from second and third law: {Delta}H{degree}(298) = 105 {+-} 2 kJ/mol and {Delta}H{degree}(298) = 160 {+-} 6 kJ/mol for reactions (1) and (2), respectively, the last referred to {alpha}CuBr{sub 2}(s).

    The first step in the diagnostic study of a pleural effusion is to classify as a transudate or exudate. Light's criteria (pleural fluid/serum proteines > 0.5; lactatedehydrogenase [LDH] > 2/3 of the upper normal limit in serum; pleural fluid/serum LDH > 0.6) usually used, incorrectly classify some cases, especially transudates. For this reason, different alternative criteria has been proposed: pleural fluid cholesterol, pleural fluid/serum cholesterol ratio, pleural fluid/serum bilirubin ratio, and serum/pleura albumin ratio. Althought the first results suggested better results that those obtained with the Light's criteria, after the analysis of the different studys we conclude that a method to diferentiate perfectly transudates and exudates is not yet available.

    Sequential computed tomographic (CT) studies of 11 patients (aged five months to seven years) with intractable epilepsy treated with synthetic ACTH-Z showed brain shrinkage in all cases. Brain shrinkage started to appear on daily ACTH injections for seven days, reached the maximum within four weeks of administration (14 injections every day and then 7 injections every other day), and almost returned to the original status in seven out of nine cases which were followed up for one to three months after the therapy. The subjects aged less than two years showed more remarkable brain shrinkage than did those aged more than five years. Furthermore, two other cases were complicated by subdural effusion after ACTH therapy. It is the authors' assumption that both of these phenomena are caused by the high concentration of corticosteroid through a change of the water and electrolyte contents in the brain.

Stance phase, sagittal plane knee joint kinematics and thigh muscular EMG profiles were compared pre- and post-insufflation utilizing a paired t-test ( = 0.05). Mild knee effusion caused a reduction in vastus medialis (p = 0.005) and lateralis (p = 0.006) EMG activity. The rectus femoris, biceps femoris and medial hamstring muscles did not exhibit changes due to this protocol. There were no changes in the sagittal plane knee joint kinematic pattern. Twenty cc effusion can cause quadriceps inhibition in the vastus medialis and the vastus lateralis in otherwise healthy individuals during jogging. This study provides baseline data for the effects of mild knee joint effusion on thigh musculature during jogging. Key Points 20 cc of knee effusion can cause vastus medialis and lateralis inhibition as noted by decreases in EMG amplitude. This effusion does not appear to alter sagittal plane knee joint kinematics during jogging. This finding if different from previous work investigating knee joint kinematic changes during a less dynamic activity (gait) with 20 cc of effusion. PMID:24431955

    We investigated the clinical characteristics of pleural effusion in systemic lupus erythematosus (SLE). A prospective analysis of 17 SLE patients with pleural effusion (seven lupus pleuritis, eight transudative effusions and two parapneumonic effusions) was performed. Thirty non-SLE patients with pleural effusion were recruited as controls. A pleural fluid ANA titer ≥1:160 was found in 8/17 (47.1%) SLE patients and none of the 30 non-SLE patients (p = 0.0001). Pleural fluid to serum C3 ratios were significantly lower in SLE than in non-SLE (median (minimum-maximum) 0.29 (0.03-0.43) versus 0.52 (0.26-0.73), p = 0.0002). Among SLE patients, pleural fluid ANA titers ≥1:160 were more frequently found in patients with lupus pleuritis than in those with pleural effusion from causes other than lupus itself (85.7% versus 20.0%, p = 0.0152). Serum CRP levels were significantly increased in patients with lupus pleuritis compared with SLE patients with transudative pleural effusion (2.30 (0.30-5.66) versus 0.7 (0.12-1.47) mg/dl, p = 0.0062). In conclusion, pleural fluid ANA titer and serum CRP levels are significantly increased in lupus pleuritis.
