    A very low birth weight premature newborn developed a sudden cardiac tamponade due to parenteral fluid extravasation 1 month after central line insertion. Besides tensive pericardial effusion a bilateral pleural effusion also developed. An emergency pericardiocentesis was really life-saving and after pleural fluid removal a complete cardiorespiratory recovery was obtained. Pericardial and bilateral pleural effusions very rarely coexist as a complication of central line extravasation. PMID:19253161

    Plasmablastic lymphoma (PBL) is a rare aggressive lymphoma arising most frequently in the oral cavity of HIV-infected patients. Rare cases of PBL have been reported in extra-oral sites, as well as in HIV-negative patients. Cardiac involvement by lymphoma is very rare. The most common primary cardiac lymphoma is diffuse large B-cell lymphoma. We report an unusual case of PBL in a 49-year-old, HIV-positive man presenting with a large intracardiac mass and bilateral pleural effusions. Histological examination of the cardiac mass biopsy and cytological evaluation of the pleural fluid demonstrated large lymphoma cells with plasmablastic differentiation. By immunohistochemistry, the large lymphoma cells expressed CD30, CD45, CD138, MUM1, and kappa light chain, were weakly positive for EMA, and were negative for T-cell and B-cell markers, lambda light chain, and human herpes virus 8 (HHV8). In situ hybridization for Epstein Barr Virus-encoded RNA (EBER) was negative in large lymphoma cells. To our knowledge, in the English literature, this is the second reported case of PBL with cardiac origin and the first reported case of PBL that presents as a combination of intracardiac mass and pleural effusions.

    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. PMID:24565689

    Infections and malignancies are common causes of pleural effusion. Among infectious causes, hyperinfection syndrome of Strongyloides stercoralis may occur in immunosuppressive patient. A 62-year-old man, known case of Non-Hodgkin lymphoma (NHL) was presented with recurrent NHL stage IV and had undergone salvage chemotherapy. Patient subsequently developed pneumonia with bilateral pleural effusion and ascites. We reported rhabditiform larvae of S. stercoralis in pleural fluid of both lungs without infiltration by lymphoma cells. Stool for microscopic examination also revealed rhabditiform larvae of S. stercoralis. This patient was a known case of NHL receiving chemotherapy resulting in immunosuppression state. Although S. stercoralis infection is not very common compared to other parasitic infections, it is common in immunosuppressive patients and may present with hyperinfection. Therefore, awareness of this parasite should be kept in mind in immunosuppressive patients. PMID:21602770

    We conducted a prospective, observational study over a 3-year period to compare the clinical, functional, and surgical findings in children with chronic bilateral otitis media with effusion who underwent one of three different types of treatment. Our study population was made up of 150 patients-79 boys and 71 girls aged 24 to 84 months-who were randomly assigned to one of the three treatment groups of 50 patients each. One group was treated with myringotomy, tympanostomy tube insertion, and adenoidectomy (T+A group); another with a combination of physical conservative treatment and adenoidectomy (P+A group); and the third with physical conservative treatment alone (P-only group). Hearing levels and tympanogram trends were evaluated during a follow-up of 12 months. In the T+A group, we noted a stable normalization of hearing in 95 of the 100 ears. Treatment with the P+A combination resulted in an improvement of hearing in 79 ears, but the improvement was maintained in only 27 ears during 12 months of follow-up. In the group with the P-only regimen, an amelioration of hearing was registered in 76 ears, but it was unstable in all cases. A type A tympanogram was maintained during the follow-up period for 2 ears in the P+A group and for 4 ears in the P-only group. Myringotomy with a detailed examination of the tympanic cavity in all ears with prolonged abnormal audiologic results revealed that types C and B tympanograms, which were found in most ears in the P+A and P-only groups, corresponded to middle ear chronic inflammatory changes (retraction pockets, granulations, adhesions, etc.) Based on our findings, we conclude that the use of a physical conservative treatment with or without an adenoidectomy does not prevent the development of chronic adhesive and purulent otitis media.

    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. PMID:26319226

    Subdural effusion (SDE) in an infant is a rare clinical scenario, which may be secondary to a variety of etiologies. Massive SDE is an extremely rare complication of head injury. It usually runs a self-limiting course. Though neurosurgical intervention is occasionally needed, different methods of surgical procedure for management includes burr-hole alone, burr-holes with subdural drain placement, twist drill craniotomy with drain and even craniotomy. The authors report a rare case of progressive massive SDE, which despite bilateral burr-hole placement and drainage failed and presented with visual deterioration and massive bulge of scalp at burr-hole sites producing rabbit ear sign in a 10 month old infant. Ultimately cystoperitoneal shunt was carried out in a desperate attempt to prevent impending rupture of scalp sutures at sites of previous burr-hole placement. Astonishingly not only complete resolution of hygroma, but visual recovery also took place. Patient is doing well at 6 months following shunt with regaining normal vision and appropriate developmental milestones. A magnetic resonance imaging scan of brain at last follow-up revealed mild ventriculomegaly with subduro-peritoneal shunt in situ and rest of brain was unremarkable. Such cases have not been reported in literature until date. PMID:24470822

  9. Economic evaluation of surgical insertion of ventilation tubes for the management of persistent bilateral otitis media with effusion in children

    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

    Photopyroelectric calorimetry in the front detection configuration (FPPE) and photothermal radiometry (PTR) were simultaneously used, together with the thermal-wave resonator cavity method (TWRC), in order to investigate the thermal effusivity of solids inserted as backing layers in a detection cell. A new combined FPPE-PTR-TWRC setup was designed. It was demonstrated experimentally that the PTR technique, combined with the TWRC method, is able to provide calorimetric information about the third layer of a detection cell. Applications on solids with different values of the thermal effusivity (starting from metals, down to thermal isolators) are presented. The values of the thermal effusivity obtained with the PTR technique are similar to those obtained with the PPE technique, and in agreement with literature values; the two methods reciprocally support each other. The accuracy of both methods is higher when the values of the thermal effusivity of the backing layer and coupling fluid are close.

    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 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. PMID:27485497

    The first case of bilateral orbital preseptal cellulitis complicating combined adenotonsillectomy and strabismus surgery is reported. The issues of antimicrobial prophylaxis are discussed. The authors speculate about the possible routes of surgical site infection. Transient bacteraemia secondary to adenotonsillectomy may be theoretically a source of distant surgical site infection to the orbit, raising the issue of distant surgical site contamination during multidisciplinary surgery. Combined adenotonsillectomy and eye surgery might benefit from prophylactic systemic antibiotic administration. PMID:23664368

    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. PMID:24721286

    Of the 1.5 million people diagnosed with pleural effusion in the USA annually, ~178 000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied.This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The aetiology of the effusions was determined using standardised criteria. Mortality was determined at 30 days and 1 year.247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1-year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign aetiologies (29% and 55%), congestive heart failure (22% and 53%), and renal failure (14% and 57%, respectively). Patients with bilateral, relative to unilateral, pleural effusion were associated with higher risk of death at 30 days and 1 year (17% versus 47% (hazard ratio (HR) 2.58, 95% CI 1.44-4.63) and 36% versus 69% (HR 2.32, 95% CI 1.55-3.48), respectively).Patients undergoing thoracentesis for pleural effusion have high short- and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign aetiologies, congestive heart failure and renal failure. Bilateral pleural effusion is distinctly associated with high mortality. PMID:25837039

    Lymphatic filariasis is one of the major public health problems across the globe. Clinical manifestations usually depend on the site of lymphatic involvement. A 21-year-old female resident of a non-endemic filarial region presented with axillary lymphadenopathy, bilateral pleural effusion, ascites and pedal oedema. Fine-needle aspiration cytology (FNAC) of axillary lymph nodes revealed microfilariae. On the administration of diethyl carbamazine, lymph nodes gradually disappeared, the patient improved symptomatically and the filarial antigen test after treatment was negative. We report this case of bilateral axillary lymphadenopathy with pleural effusion and ascites as a rare manifestation of filariasis. PMID:21914673

    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. PMID:25474338

    OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP) with lung bulla. 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

    We report a family of three siblings followed between 2005 and 2011 with bilateral combined hamartoma of the retina and retinal pigment epithelium, with the age of diagnosis ranging from 7 to 13 years. The main reason for consultation was reduction of vision and squint. The diagnosis was determined based on the clinical findings on fundus examination: increased pigmentation at the macula with slightly elevated, gray-white macular lesion, tortuosity of perimacular blood vessels and glial epiretinal membrane. The elder brother was found to have left posterior subcapsular cataract. He was also confirmed to have neurofibromatosis type 1, the youngest sister fit in the diagnostic criteria for neurofibromatosis type 1, while the middle sister was presumed to have neurofibromatosis type 1. Follow-up showed stability of the retinal lesion in the three cases, with the progression to develop right posterior subcapsular cataract in the elder sister. This report is aimed to demonstrate that the occurrence of bilateral combined hamartoma of the retina and retinal pigment epithelium could raise the possibility of associated neurofibromatosis.

    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 treatments with composite prosthesis require the completion of milling. These precision preparations in the fixed prosthesis promote the integration of removable partial denture with metallic framework in mechanical (prosthetic balance), physiological, aesthetical and psychological point of view. Their conception and realization are always subordinated to the balance principles of the removable partial denture. The precision they require need the use of a dental milling machine working along the predetermined insertion axis of the partial denture casting and require an excellent communication and a close collaboration between dentist and experienced technician of laboratory. In this paper, after a recalling about the milling (definition, description, interests), we will detail the steps to achieve clinical and laboratory needs for a rehabilitation by composite prosthesis combining milling, and it will be illustrated through a clinical case with a bilateral tooth-supported edentulous in the maxilla.

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.

    Carbimazole, an antithyroid drug, is associated with a significant number of side effects, but pleuropulmonary complications are rare. We report the case of a 42-year-old Caucasian man who developed dyspnoea secondary to bilateral exudative pleural effusions while on carbimazole therapy. Extensive investigations, including a vasculitic screen, ruled out other potential causes for this patient's clinical presentation. This patient's pleural effusions gradually resolved within a few months of stopping carbimazole therapy, suggesting a role for the latter in the aetiopathogenesis of his presentation. Clinicians should consider discontinuing treatment with carbimazole and introducing alternative antithyroid therapy in this setting, once other potential causes of a pleural effusion have been systematically ruled out.

    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

    Background Fibrous tuberculous pleural effusion (TPE) represents common disease in tuberculous clinic. Medical thoracoscopy has been used to treat pleural empyema and shown promising outcomes, but data of its use in multiloculated and organized TPE remains limited to know. Methods The study was performed on 430 cases with TPE. The cases were divided into free-flowing, multiloculated effusion and organized effusion group. Each group was subdivided into two or three types of therapeutic approaches: ultrasound guided pigtail catheter, large-bore tube chest drainage and medical thoracoscopy. Patients with multiloculated or organized effusions received streptokinase, introduced into the pleural cavity via chest tubes. The successful effectiveness of the study was defined as duration of chest drainage, time from treatment to discharge days and no further managements. Results Patients with organized effusion were older than those with free-flowing effusion and incidence of organized effusion combined with pulmonary tuberculosis (PTB) was higher than those of multiloculated effusion and free-flowing effusion respectively. Positive tuberculosis of pleural fluid culture was higher in organized effusion than that in free-flowing effusion. Sputum positive for acid-fast bacillus (AFB) in organized effusion was higher than that in multiloculated effusion and free-flowing effusion. Medical thoracoscopy showed significant efficacy in the group of multiloculated effusion and organized effusion but free-flowing effusion. No chronic morbidity and mortality related to complications was observed. Conclusions Medical thoracoscopy was a safe and successful method in treating multiloculated and organized TPE.

    In order to determine variables that correlate with malignant pleural effusion and mortality in patients with lymphoproliferative disorders and pleural effusion, a retrospective study was performed. Clinical data of hospitalized patients with a lymphoid malignancy and pleural effusion who underwent thoracentesis from January 1993 to December 2002 were collected. A logistic regression analysis was carried out to determine prognostic variables that predict malignant pleural effusion and hospital mortality. There were 86 patients who were admitted on 91 occasions. The median age was 70 years (range 4 - 92) and the male:female ratio was 44:42. Sixty-four patients (74%) had advanced disease, 43 (50%) had received prior chemotherapy and 9 (10%) were in remission. Of 91 cases of pleural effusions, 44 (48%) were bilateral, 80 (88%) were exudates and 48 (53%) were due to malignant involvement of pleura. In multivariate analysis, symptomatic pleural effusion (odds ratio 10.3, 95% confidence interval 1.7 - 98.3), pleural fluid mesothelial cell count < 5% (odds ratio 8.0, 95% confidence interval 1.4 - 58.2), pleural fluid:serum lactate dehydrogenase (LDH) > or =1 (odds ratio 6.4, 95% confidence interval 1.2 - 45.6) and pleural fluid lymphocyte percentage > or =50 (odds ratio 6.4, 95% confidence interval 1.2 - 50) were significantly correlated with malignant effusion. A secondary cancer (odds ratio 11.9, 95% confidence interval 2.3 - 88.8), pleural fluid:serum LDH > or =1 (odds ratio 10.9, 95% confidence interval 2.6 - 64.9), and pneumonia (odds ratio 6.4, 95% confidence interval 1.7 - 28.6) were significantly correlated with hospital mortality. In conclusion, malignant pleural effusion is the common etiology of pleural effusion in patients with lymphoid malignancy. Many clinical and cytochemical markers have discriminatory values in identifying malignant effusion. A high pleural fluid to serum LDH level correlates with malignant pleural involvement and hospital mortality. PMID

  12. Combined type IIIB with bilateral type I thyroplasty for pitch lowering with maintenance of vocal fold tension

    Objective To evaluate type IIIB thyroplasty using the excised larynx bench apparatus and determine how altering vocal fold contour by performing bilateral medialization of the inferior vocal fold affects phonation. This procedure could be performed in patients for whom pitch lowering is desirable, such as female-to-male transsexuals or male patients with mutational falsetto in whom intensive voice therapy was insufficient. Methods Aerodynamic, acoustic, and high-speed videokymographic data were collected for nine larynges at three subglottal pressure inputs for each of three conditions: normal; type IIIB thyroplasty; and combined type IIIB with modified bilateral type I thyroplasty intended to create a more rectangular glottal configuration. Each larynx served as its own control. Results Phonation threshold flow (p=0.005), phonation threshold power (p=0.031), and airflow varied across conditions with highest values for type IIIB thyroplasty and lowest for the combined procedure. Fundamental frequency was significantly different (p<0.001), decreasing by approximately 100 Hz from control to type IIIB trials, and then by approximately 15 Hz from IIIB to combined procedure trials. Vibratory amplitudes and intrafold phase difference were highest for type IIIB trials. Conclusions Addition of bilateral inferior medialization to type IIIB thyroplasty provided some further decrease in frequency, but mostly served to increase tension, reduce airflow, and produce a vibratory pattern which more closely mirrored control trials. Exploration of this combined procedure in patients may be warranted if not completely satisfied with the results from type IIIB thyroplasty alone. PMID:24241252

    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.

    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.

    Lemierre's syndrome is a septic thrombophlebitis of the internal jugular vein, which can lead to severe systemic illness. We report a case of an otherwise healthy 26-year-old man who suffered from pharyngitis followed by septic shock requiring intubation and vasopressor support from Fusobacterium necrophorum bacteremia. The septic emboli to his lungs caused complicated bilateral parapneumonic effusions, which recurred after initial drainage. He required bilateral chest tubes and intrapleural tPA to successfully drain his effusions. His fever curve and overall condition improved with the resolution of his effusions and after a 33-day hospitalization, he recovered without significant disability. The severity of his illness and difficult to manage complicated parapneumonic effusions were the unique facets of this case. Using an evidence-based approach of tPA and DNase for complicated parapneumonic effusions in Lemierre's syndrome can be safe and effective. PMID:26744664

    PubMed

    Formenti, P; Umbrello, M

    2014-02-01

    Pleural effusion is a fluid collection within the pleural space and is a common finding in mechanically ventilated patients. It is frequently related to fluid overload, hyponcotic states, heart failure, and altered pleural pressure due to atelectasis or pneumonia. Recent literature has shown that its incidence within ARDS is increasing, even if, in most of cases, at least in the early phases, it seems of limited clinical relevance. Most of the knowledge of Pleural Effusion and of its interaction with lung/chest wall mechanics derives from a small number of experimental studies and from some clinical studies, in most of the cases performed with normal lung parenchyma. In ARDS, however, Pleural Effusion seems to have a little effect "per se" on tidal mechanics and oxygenation (increasing elastance and reducing PO2), that are already profoundly affected by the lung injury itself. To sum up all the observations, we can assume that Pleural Effusion alters regional transmural pressure, restricting more the inspiration phase, and creating an opening/closure effect that can be reverted by PEEP application in recruitable lungs. This restores volume and compliance only if the abdomen is normally expansible. Drainage of Pleural Effusion is frequently performed in ICU but the benefits and risks are not well established. Lung ultrasound is an effective technique with high sensitivity and specificity for both bedside diagnosis and drainage guidance. It may help to quantify and qualify the effusion and at the same time the grade of aeration of underling parenchyma. Aim of this review is to summarize the current evidence and opinions about the interaction between Pleural Effusion and positive pressure ventilation in the presence of ARDS, its impact on gas exchange and tidal mechanics, trying to figure out the best bedside management that is not available yet. The estimation of both lung and chest wall elastance may help in the clinical decision making whether to drain or not in

    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.

    Metastatic melanoma is a rare form of skin cancer, but one that comes with a high mortality rate. Pulmonary involvement is frequently seen in metastatic melanoma with only 2% of malignant melanoma patients with thorax metastasis presenting with pleural effusions. Herein, we report an extremely rare case of black pleural effusion from thoracic metastasis of cutaneous malignant melanoma. A 74-year-old man with known metastatic melanoma presented with a 1-month history of worsening lower back and hip pain and was found to have extensive osseous metastatic disease and multiple compression fractures. The patient underwent an uneventful kyphoplasty; however, the following day, he became acutely hypoxic and tachypneic with increased oxygen requirements. Radiographic evaluation revealed new bilateral pleural effusions. Bedside thoracentesis revealed a densely exudative, lymphocyte-predominant black effusion. Cytological examination showed numerous neoplastic cells with melanin deposition. A diagnosis of thoracic metastasis of malignant melanoma was established based on the gross and microscopic appearance of the pleural fluid. To the best of our knowledge, this is the first reported case of black pleural effusions secondary to metastatic melanoma in the United States. Despite the rarity of this presentation, it is important to determine the etiology of the black pleural effusion and to keep metastatic melanoma as a differential diagnosis. PMID:26078741

    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.

  6. Diagnostic Tools of Pleural Effusion

    PubMed Central

    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.

    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

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. PMID:24486113

    Abstract Objective: 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. Methods: 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. Results: 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 >2500g 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. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. PMID:26559603

    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.

    Pleural effusions are resistant to standard therapy, which causes discomfort and can require prolonged hospitalization. As an alternative, pleuroperitoneal shunting for pleural effusions of various etiologies was evaluated. We implanted 36 shunts in 29 patients. Two patients had bilateral shunts and five had shunt revisions. The effusion was related to a malignancy in 22 patients, postoperative chylothorax in two patients, and other causes in five patients. Therapeutic thoracentesis had been attempted in 28 patients, and eight had had chest tube placement previously with attempted sclerosis. Seven patients had a trapped lung syndrome. There was no operative mortality. All patients were deemed ready for discharge from the hospital if they had recovered from the operation within 48 hours. Five patients had poor results, either because of a moribund status or their refusal or inability to pump the shunt. Of the remaining 24 patients, four had good results with temporary improvement, and excellent results were achieved in 20 patients (83.3%), who experienced symptomatic relief and stabilization or regression of pleural effusion until the time of their death. Patients with chylothorax experienced complete resolution. The 14 patients with malignant effusions had a median survival of 4 months, and there were no instances of peritoneal tumor seeding. In conclusion, pleuroperitoneal shunting is an alternative therapy for pleural effusions that requires a limited hospitalization only, is associated with minimal and short-term discomfort, achieves excellent results in properly selected patients, and is the only viable therapy when lung expansion cannot be achieved.

    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 objective of this article was to determine the long-term outcome of surgical treatment in a patient with bilateral congenital aniridia and congenital cataracts. The patient was treated by cataract removal and implantation of a single piece IOL in both eyes. Two aniridia rings were also implanted in the capsular bag. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), stability of the intraocular lens (IOL) and subjective glare reduction were measured for two years after the surgery. After 10 months, the IOP in the left eye had increased to 26 mmHg despite the fact that anti-glaucoma medication was added. Therefore, the patient was scheduled for an Ahmed valve implantation. These results suggest that good visual outcomes can be achieved in patients with bilateral congenital aniridia and cataracts. Nevertheless, the IOPs must be continuously monitored, and glaucoma screening performed to prevent further complications. PMID:26949363

    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. PMID:27041165

    Pleural tuberculosis is the first or second most common form of extrapulmonary tuberculosis as well as the main cause of pleural effusion in many countries. It is rare in young infants and is more common in children over 10 years of age. We report the case of a 19-month-old girl admitted for prolonged fever with unilateral pleural effusion. The mother reported a history of lymph node tuberculosis 6 years previously. Intravenous antibiotics with cefotaxime and vancomycin were started. Thoracocentesis yielded a serosanguinous exudate fluid with a lymphocyte predominance. The tuberculin skin test and PCR GeneXpert(©) on pleural fluid were negative. The initial outcome was favorable, but the chest X-rays 10 days after discharge showed bilateral pleural effusion. Pleural biopsy was proposed but the culture of pleural fluid was positive for Mycobacterium tuberculosis. The child was put under standard treatment for tuberculosis. The outcome was favorable.

    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. PMID:26392449

    A bilateral comparison study of the therapeutic effects of broad-band ultraviolet (UBV) (FS-40 Sunlamp bulbs) radiation versus UVB radiation plus methoxsalen was conducted in patients with psoriasis. Ten patients were given up to 30 exposures to the two treatments on paired, similarly affected limbs. There was no detectable difference in the response of limbs treated with UVB plus methoxsalen versus UVB phototherapy alone although all patients did show a therapeutic response. Other areas of the body treated with methoxsalen and broad-band UVA radiation (PUVA bulbs) responded more rapidly and to a greater extent than areas exposed to UVB radiation. PMID:7654566

    Primary malignant myelomatous pleural effusion (PMMPE) occurs in less than 1% of patients with multiple myeloma and is diagnosed either by visualization of plasma cells on cytology or by positive flow cytometry. The presence of immature plasma cells characterized by high nucleus to cytoplasm ratio, visible nucleolus and presence of Mott cells and Russell bodies are independent poor prognostic factors. The clinician should differentiate PMMPE from secondary pleural effusion as it is associated with a significantly worse prognosis and poor overall survival. PMID:27525090

    We present a case of posterior atlantoaxial screw-rod fixation in a patient with an aberrant vertebral artery (VA) course combined with bilateral high-riding VA. An aberrant VA which courses below the posterior arch of the atlas (C1) that does not pass through the C1 transverse foramen and without an osseous anomaly is rare. However, it is important to consider an abnormal course of the VA both preoperatively and intraoperatively in order to avoid critical vascular injuries in procedures which require exposure or control of the VA, such as the far-lateral approach and spinal operations.

    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.

    Thoracic sonography is an important tool in diagnosis and assessment of pleural effusions and can provide valuable information about the characteristics of accumulated pleural fluid, in addition to improving the safety of thoracentesis. In addition to the 4 classic sonographic pleural effusion patterns (anechoic, complex nonseptate, complex septate, and homogeneously echogenic), an echogenic swirling pattern has been previously described, which was originally thought to be associated with malignant effusion. Two cases of pleural effusion with an echogenic swirling pattern are described below, illustrating that this sonographic finding can be seen in both exudative and transudative effusions.

    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.

    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. PMID:23453662

    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.

    Background The ability of stroke volume variation (SVV), pulse pressure variation (PPV) and global end-diastolic volume (GEDV) for prediction of fluid responsiveness in presence of pleural effusion is unknown. 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. Methods 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. Results 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. Conclusions In this porcine model, bilateral pleural effusion did not affect the ability of SVV, PPV and GEDV to predict fluid responsiveness. PMID:23418546

    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

    The hypersensitivity reactions induced by drugs, some widely used, like central nervous system medication, can have various presentations. The lung is a frequent target for such events. We present the case of 40-year-old male patient, non-smoker, with infant encephalopaty, seizures since age of 6 with polimorphic crisis (mainly absences), with anticonvulsivant treatment since 2011 (carbamazepine, sodium valproate, levetiracetam), with no respiratory medical history. Current symptoms started two weeks before, with chest pain, dry cough. He received no antibiotics. Chest X-ray and thoracic CT scan (27 June 2013) showed a left pleral effusion. Left exploratory thoracocentesis extracted 20 ml reddish pleural fluid: eosinophilic exsudate (60%) with normal adenosin deaminase. He also presents moderate blood eosinophilia (13.7%-1780/mm3). Pulmonary infarction with secondary pleurisy, thoracic trauma, acute pancreatitis with secondary pleurisy were excluded. No Loeffler transient infiltrates were documented, serology for Toxocara is IgG positive (historical) and not significant for current episode, no symptoms suggestive for toxocarosis (characteristic to young children, patient had no liver enlargement etc.), no hidatidosis or trichinelosis were found. As an exclusion diagnosis, a hypersensitivity reaction to anticonvulsivant medication was considered (mentioned in literature) carbamazepine and sodium valproate (even if medication was taken for a longer time), with blood and pleural eosinophilia. Together with the neurologist, the mentioned drugs were stopped and he was started on lamotrigine 2 tb/day and levetiracetam 1 tb/day, well tolerated, no absences were noticed. Total remission of blood eosinophilia and partial remission of pleural effusion were noticed. Subsequent follow-ups confirm favourable evolution, with healing of pleurisy and normal blood cell count, which are stable at 7 months after changing anticonvulsivant treatment. PMID:25241560

    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

    Central venous catheter is commonly utilized as a hemodialysis access in the pediatric population. Long-standing central venous catheters can be complicated by superior vena cava (SVC) stenosis and thrombosis that can rarely present as pleural effusions. We report a case of a 5-year-old boy on chronic hemodialysis who presented with combined pleural and pericardial effusions, which was secondary to catheter induced SVC stenosis. Both the pleural effusion and the pericardial effusion in this patient subsequently improved with the relief of SVC stenosis. This case report highlights the serious complications of SVC stenosis associated with long-standing central venous catheters which is an under-recognized problem in the pediatric population.

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

    Additive manufacturing techniques may be utilized to construct effusion plates. 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 authors made a retrospective analysis of 51 patients with non-small-cell lung cancer with pleural effusion, not associated with tumor lesion of pleural leaves. Out of 51 operated patients 45 (88%) proved to be resectable. Among 45 patients (20 pneumonectomies, 24 lobectomies and 1 bilobectomy) combined interventions were fulfilled in 15 patients. In 27 (60%) out of 45 patients there was an injury of mediastinal lymph nodes, in 13 (29%)--intrapulmonary and root nodes. Complicated course of the postoperative period was noted in 27% of patients, lethality was 2%. One year survival after resection was 86%, three and five year survival was 54% and 30% respectively. The indices of survival reliably depended on the degree of lymphogenic dissemination. The presence of pleural effusion can not be a reason for refusal to fulfill radical surgical intervention.

    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.

  5. Multiresolution Bilateral Filtering for Image Denoising

    2008-01-01

    The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges; it has shown to be an effective image denoising technique. An important issue with the application of the bilateral filter is the selection of the filter parameters, which affect the results significantly. There are two main contributions of this paper. The first contribution is an empirical study of the optimal bilateral filter parameter selection in image denoising applications. The second contribution is an extension of the bilateral filter: multiresolution bilateral filter, where bilateral filtering is applied to the approximation (low-frequency) subbands of a signal decomposed using a wavelet filter bank. The multiresolution bilateral filter is combined with wavelet thresholding to form a new image denoising framework, which turns out to be very effective in eliminating noise in real noisy images. Experimental results with both simulated and real data are provided. PMID:19004705

    A Standardbred filly was admitted for evaluation of pleuritis and pneumonia. Heart rate was 80 to 120 beats/min, and the pulse was barely palpable. Thoracic and abdominal ultrasonography and echocardiography revealed substantial pericardial effusion with cardiac tamponade, fibrinous pericarditis, pleural effusion, and ascites. Initial electrocardiography revealed normal sinus rhythm with decreased amplitude of the QRS complexes consistent with pericardial effusion. Following thoracentesis, echocardiogram-guided pericardiocentesis was performed. Bacterial culture yielded no growth from any of the fluids, and bacteria were not seen on cytologic examination. Initial treatment included broad-spectrum antibiotic treatments, IV fluid therapy, and anti-inflammatory agent administration. On the basis of negative culture results, an immune-mediated cause was considered, and dexamethasone was instituted in a decreasing dosage regimen. Pericardial effusion, ventral edema, and ascites began to resolve within 3 days after beginning dexamethasone treatment. Thirty days following discharge, the filly was reexamined, and at that time, the prognosis for athletic performance was considered good so the horse was returned to race training. The final diagnosis in this case was idiopathic, effusive, nonconstrictive pericarditis with tamponade. Early identification, clinical understanding, and application of knowledge of the pathophysiologic mechanisms of pericarditis in horses, combined with use of diagnostic aids such as ultrasonography and aggressive therapy consisting of effusion drainage, pericardial lavage, antibiotics that penetrate the pericardium, and corticosteroids when indicated are critical for a successful outcome in horses with pericarditis.

    Carcinoembryonic antigen (CEA), carbohydrate antigens 15–3, 19–9 and 72–4 (CA 15–3, CA 19–9 and CA 72–4), cytokeratin 19 fragments (CYFRA 21–1), neuron-specific enolase (NSE) and squamous cell carcinoma antigen (SCC) were evaluated in pleural fluid for the diagnosis of malignant effusions. With a specificity of 99%, determined in a series of 121 benign effusions, the best individual diagnostic sensitivities in the whole series of 215 malignant effusions or in the subgroup of adenocarcinomas were observed with CEA, CA 15–3 and CA 72–4. As expected, a high sensitivity was obtained with SCC in squamous cell carcinomas and with NSE in small-cell lung carcinomas. CYFRA and/or CA 15–3 were frequently increased in mesotheliomas. Discriminant analysis showed that the optimal combination for diagnosis of non-lymphomatous malignant effusions was CEA + CA 15–3 + CYFRA + NSE: sensitivity of 94.4% with an overall specificity of 95%. In malignant effusions with a negative cytology, 83.9% were diagnosed using this association. The association CYFRA + NSE + SCC was able to discriminate adenocarcinomas from small-cell lung cancers. Regarding their sensitivity and their complementarity, CEA, CA 15–3, CYFRA 21–1, NSE and SCC appear to be very useful to improve the diagnosis of malignant pleural effusions. © 1999 Cancer Research Campaign PMID:10576665

    Discoid menisci can be a source of pain for patients, and pose treatment challenges to the treating surgeon. Additional associated intra-articular pathology, specifically osteochondral defects, can further complicate the clinical picture. The incidence of lateral discoid meniscus is variable based on the population, with a range of 0.4 to 17%, with bilateral involvement in up to 19% of these cases. Osteochondritis dissecans (OCD) is exceedingly rare, with an incidence of 0.015% in one study; however, some authors have suggested a correlation between the development of OCD and the presence of an unstable or torn lateral discoid meniscus. We present a case, the first to our knowledge, of bilateral lateral femoral condyle OCD in the presence of bilateral, asymptomatic, complete lateral discoid menisci. PMID:23288777

    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

    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 (10(7) 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

    An 11-year-old Quarter Horse mare was presented with ventral edema and pleural effusion, secondary to a disseminated ovarian adenocarcinoma. Bilateral thoracocentesis yielded 30 L of thin, blood-tinged fluid, which was a modified transudate. Cytologic examination of the fluid revealed large atypical cells, suggestive of carcinomatous neoplasia. Similar cells were found in the peritoneal fluid. The mare was euthanatized. Necropsy revealed a 35-cm diameter mass in the cranial mediastinum, ventral to the trachea. The left ovary was 25 cm in diameter and most of the parenchyma was replaced by red or brown friable tissue, containing numerous 1-to 3-mm cysts. Papillary adenocarcinoma of the ovary was diagnosed, based on the appearance and arrangement of tumor cells in the ovary, sublumbar and tracheobronchial lymph nodes, and mediastinal mass. Ovarian neoplasia should be considered in the differential diagnosis of pleural effusion in the horse. PMID:4030465

    Objective. To describe a patient with unilateral exudative pleural effusion that developed after commencement of carbimazole. Methods. We describe the presentation and clinical journey of an elderly woman who presented to the chest physicians initially with pleural effusion but was followed up by the endocrinology team. Result. The patient was a 77-year-old Caucasian woman who presented with symptoms of breathlessness and a confirmed unilateral pleural effusion while being on treatment for thyrotoxicosis. Her symptoms needed recurrent hospital admission for investigations and drainage, but no potential cause was identified after extensive investigations. A drug-induced exudative effusion consequent to carbimazole intake was diagnosed as discontinuation of the drug lead to complete resolution of the effusion with no recurrence. Conclusion. Physicians and Endocrinologist must bear in mind that this potentially rare complication of carbimazole while treating patients of thyrotoxicosis as appearance of similar features in their patients while being on carbimazole should lead to the discontinuation of the drug, and alternative treatment strategy should be considered.

    Sjögren’s syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes in exocrine glands, specifically the salivary and lacrimal glands, resulting in the typical symptoms of xerophthalmia and xerostomia. SS may be accompanied by pleural effusion when the lung is involved, but this occurrence has been reported in only 10 cases in the literature. We report the case of a 42 year-old woman with severe bilateral pleural effusion for eight years. Primary Sjögren’s Syndrome was finally diagnosed based on the presence of xerophthalmia and xerostomia, biopsy of the minor salivary glands, and positive anti-SS-A antibody in the serum and pleural effusion. Biopsy of the parietal pleura through video-assisted thoracoscopy revealed infiltration of lymphocytes. The patient had a long history of pleural effusion without clear etiology. Malignant disease was first suspected because of abnormal density lesion on the left lung and malignant cells found on cytology, but PET-CT revealed no malignant lesion. Examinations did not support infection, malignant tumor, pulmonary sarcoidosis, or other connective tissue diseases. This data could be useful for the future study of pleural effusion in SS.

    Allergic bronchopulmonary aspergillosis (ABPA) is primarily a disease of patients with cystic fibrosis or asthma, who typically present with bronchial obstruction, fever, malaise, and expectoration of mucus plugs. We report a case of a young man with a history of asthma who presented with cough, left-sided pleuritic chest pain and was found to have lobar atelectasis and an eosinophilic, empyematous pleural effusion. Bronchoscopy and sputum cultures grew Aspergillus fumigatus, and testing confirmed strong allergic response to this mold, all consistent with a diagnosis of ABPA. This novel and unique presentation of ABPA expands on the differential diagnosis of eosinophilic pleural effusions. PMID:21311176

    Malignant pleural effusion in myeloma (MMPE) is a rare terminal event; with a median survival is four months. All the patients usually have multiple poor prognostic factors and none of them (like beta 2-microglobulin, karyotype, Stage of disease, C-reactive protein etc.) correctly predicts the survival. We are reporting a series of five cases and evaluated the factors influencing the overall survival. All of our patients had a very good response to treatment and had a better survival compared to the reported cases so far. After reviewing the literature carefully we found that timing of development of pleural effusion is probably the most important prognostic factor. Those who develop effusion after some time lag form the initial treatment, will have a poor survival (median four months) compared to those who had effusion at the start of the disease.

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.,more » 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.

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

    We investigated the thermal effusivity of silver nanofluids using a microwave technique. During microwave irradiation, silver nanoparticles with a narrow particle size distribution were formed in water and in ethylene glycol, with a polyvinylpyrrolidone stabilizer. We designed and used a front-photopyroelectric technique that employed a metalized polyvinylidene difluoride (PVDF) pyroelectric sensor, with a thermally thick sensor and sample. Using this technique, we calculated the thermal effusivity of the silver nanofluids at a given frequency using the combination of the signal's normalized amplitude-phase. The thermal effusivity of the nanofluids increased with the number of microwave irradiation cycles, which increased the nanoparticle concentration in the base fluids. A comparison with reported values illustrates the high accuracy obtained from the results of thermal diffusivity, the thermal effusivity of the PVDF sensor, and the thermal effusivity of ethylene glycol as a base fluid (differing by only 1.7 %, 0.5 %, and 2.3 %, respectively). Our method can therefore be used to study nanofluids with varying nanoparticle properties, such as concentration, size, and shape.

    Iatrogenic pneumothorax secondary to thoracentesis is relatively uncommon but does present to the emergency department (ED). Iatrogenic pneumothoraces developing tension physiology are rare. We report a case of an elderly female patient presenting to the ED with an isolated chief complaint of bilateral leg swelling, beginning the day after a thoracentesis, which was performed 3 days prior for pleural effusions secondary to lung cancer. Given that the patient was hemodynamically stable, not hypoxic, and had a history of chronic obstructive pulmonary disease and recent history of pleural effusions with diminished lung sounds throughout, this was a radiologic diagnosis. Immediately upon diagnosis, a 10F intrapleural catheter was inserted at the second intercostal space in the midclavicular line with successful resolution of the tension phenomenon. The patient tolerated the procedure well, and the catheter was removed on hospital day 2 without recurrence of the pneumothorax. She experienced resolution of her lower extremity swelling and was discharged from the hospital 2 days later. Isolated inferior vena cava syndrome secondary to a subacute tension pneumothorax was likely the cause of the patient's symptoms. This presentation is very rare and is undocumented in the literature. A high degree of suspicion for acute chest pathology should exist in every patient presenting to the ED with history of recent pleural violation. PMID:26003746

    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.

    Malignant pleural effusion (MPE) can complicate most malignancies and is a common clinical problem presenting to respiratory and cancer care physicians. Despite its frequent occurrence, current knowledge of MPE remains limited and controversy surrounds almost every aspect in its diagnosis and management. A lack of robust data has led to significant practice variations worldwide, inefficiencies in healthcare provision, and threats to patient safety. Recent studies have highlighted evolving concepts in MPE care that challenge traditional beliefs. Advancing laboratory techniques have improved the diagnostic yield from pleural fluid cytology, minimizing the need for invasive tissue biopsies, even in many cases of mesothelioma. Imaging-guided biopsy is comparable to thoracoscopy in suitable patients, if cytological examination was noncontributory. Cumulating evidence for the benefits of indwelling pleural catheters (IPCs) has led some centers to adopt this approach as first-line definitive management for MPE over conventional talc pleurodesis. The optimal technique of talc pleurodesis is still debated despite its use for many decades. Strategies combining pleurodesis and IPC are being studied. MPE consists of a heterogenous group of diseases and careful phenotyping of malignant effusion patients can provide important clinical information that will advance the field and allow better stratification of patients and planning of therapy accordingly. This review addresses the controversies in MPE diagnosis and management and exposes the deficits in knowledge of MPE that should be the focus of future research. PMID:25463163

    Background: Small round cell tumors (SRCTs) are a group of tumors composed of small, round, and uniform cells with high nuclear/cytoplasmic (N/C) ratios. The appearance of SRCT neoplastic cells in the effusion fluid is very rare. We reported the cytomorphological findings of SRCTs in effusion cytology, and performed statistical and mathematical analyses for a purpose to distinguish SRCTs. Materials and Methods: We analyzed the cytologic findings of effusion samples from 40 SRCT cases and measured the lengths of the nuclei, cytoplasms, and the cell cluster areas. The SRCT cases included 14 Ewing sarcoma (EWS)/primitive neuroectodermal tumor cases, 5 synovial sarcoma cases, 6 rhabdomyosarcoma cases, 9 small cell lung carcinoma (SCLC) cases, and 6 diffuse large B-cell lymphoma (DLBL) cases. Results: Morphologically, there were no significant differences in the nuclear and cytoplasmic lengths in cases of EWS, synovial sarcoma, and rhabdomyosarcoma. The cytoplasmic lengths in cases of SCLC and DLBL were smaller than those of EWS, synovial sarcoma, and rhabdomyosarcoma. The nuclear density of the cluster in SCLC was higher than that in other SRCTs, and cases of DLBL showed a lack of anisokaryosis and anisocytosis. Conclusion: We believe that it might be possible to diagnose DLBL and SCLC from cytologic analysis of effusion samples but it is very difficult to use this method to distinguish EWS, synovial sarcoma, and rhabdomyosarcoma. Statistical and mathematical analyses indicated that nuclear density and dispersion of nuclear and cytoplasmic sizes are useful adjuncts to conventional cytologic diagnostic criteria, which are acquired from experience.

    There is no detailed information about benign asbestos pleural effusion (BAPE). The aim of the study was to clarify the clinical features of BAPE. 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

    The therapeutic options available for the management of malignant pleural effusions associated with a restricting malignant cortex remain unsatisfactory. The efficacy of pleuroperitoneal shunts was evaluated in 16 patients with recurrent malignant effusions. There were no operative deaths; one patient died on the third postoperative day as a result of lymphangitis carcinomatosa. The median hospital stay was five (range 3-21) days. Palliation was obtained in all but one of the other 15 patients. There was no appreciable reaccumulation of pleural fluid as judged by radiography. Two patients developed occlusion of the shunt. In one case this was due to blood clots in the pleural catheter and necessitated insertion of a new shunt. The other shunt was removed because of obstructing infected fibrin debris, and a rib resection was performed. There were eight deaths related to the underlying malignancy after a mean interval of 7.3 (range 1.5-23) months. The other six patients are still alive, with a mean survival of 11.0 (range 5-20) months, and have achieved good symptomatic relief. The insertion of a pleuroperitoneal shunt can offer effective palliation for patients with recurrent malignant pleural effusions. Images PMID:1696401

    Malignant mesothelioma is a tumour of serous surfaces mainly arising at the pleura or the peritoneum. The diagnosis encompasses multiple problems as there is no pathognomonic hallmark for the disease, there are multiple histological types and the differentiation from other tumours, such as adenocarcinoma or metastatic pleural disease, can represent quite a challenge. Usually a diagnosis of malignant mesothelioma carries a dismal prognosis with scarce therapeutical options.The present report concerns a patient with a diagnosis of malignant pleural mesothelioma with endobronchial extension. Biopsy specimens were obtained through fibreoptic bronchoscopy and blind needle pleural biopsy. The final diagnosis was only possible after careful histological evaluation with a combination of immunohistochemical markers. PMID:21686530

    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. PMID:18441854

    Chylothorax is accumulation of chylous fluid in the pleural space due to impaired integrity of the thoracic duct or its branches. In childhood, the causes differ from those in adults because children less frequently develop malignancies and are more resistant to trauma. Commonly, chylothorax occurs as a complication of tumoral invasion or cardiopulmonary surgery. Treatment of chylothorax is essentially medical. In the event of medical treatment failure or a massive effusion, surgery is needed. We describe the case of a 65-year-old woman who developed bilateral chylothorax after a simple cough. She was treated with a medium-chain triglyceride diet and thoracentesis. PMID:24928644

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. PMID:27297664

    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.

It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication.

    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

    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

    Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH) produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that non-labyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained. PMID:22207864

  5. Echinoderms Have Bilateral Tendencies

    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

    The aim of this study is to evaluate connection of plasma level of beta2-microglobulin, C-reactive protein and uric acid as well as sonographic parameters like thickness of synovial membrane, thickness of femoral condylar cartilage and presence of joint effusion and Baker's cysts with bilateral knee pain in dialyzed patients, comparing them with parameters in asymptomatic dialyzed patients. Plasma levels of beta2-microglobulin and C-reactive protein were significantly higher in symptomatic patients while uric acid level showed no difference among the groups. In symptomatic patients synovial membrane was thicker and in those patients there were more knee effusions and Baker's cysts. Thickness of femoral condylar cartilage showed no difference between groups. That suggests that inflammatory mechanisms developing from beta2-microglobulin accumulation could be important factor in bilateral knee pain in dialyzed patients even in shorter duration dialysis.

    Background Infantile purulent meningitis (PM) is a commonly severe intracranial infectious disease in infants under age 1 year. In recent years, several diagnostic and treatment methods were reported, but in these cases the neurological complications and sequel were often observed, among which subdural effusion (SE) is the most common complication in PM. Timely diagnosis and early intervention are vital for better outcomes. In this study, the surgical treatments for infantile PM complicated by SE were investigated. Material/Methods Patients who had PM complicated by SE in the Children’s Hospital of Hebei Province from June 2000 to June 2012 were retrospectively analyzed and 170 patients were enrolled in the study. Surgical treatment for each patient was adopted according to producing effusion time, leucocyte count, protein content, intracranial pressure, and bacteria culture, coupled with cranial ultrasound examination, CT, and MRI scans. Results Nearly, 15 patients were cured using serial taps, with a 50% cure rate. Seventeen out of 30 (56.6%) patients receiving subcutaneous reservoir drainage had better outcome. Nearly 80% of patients (55/69) who underwent minimally invasive trepanation and drainage were positive. Surgical procedure of minimally invasive trepanation and drainage combined with drug douche was effective in 63% of patients (19/30). In addition, 6 patients were cured with subdural-peritoneal shunt. Only 1 patient died, after the recurrence of meningitis, and the remaining 4 patients were cured by craniotomy. Conclusions For infantile PM complicated with SE, treatment needs be chosen according to the specific situation. Surgical procedure of minimally invasive trepanation and drainage is a very effective treatment in curing PM complicated by SE. The treatment was highly effective with the use of drug douche. Subdural-peritoneal shunt and craniotomy were as effective as in refractory cases. PMID:26482715

    The source of massive pleural effusion was not apparent in a 58-year-old man who had cirrhosis but no demonstrable ascites. Intraperitoneal injection of technetium Tc 99m sulfur colloid established the presence of peritoneopleural communication. This diagnostic technique can be helpful in evaluating patients with cirrhosis of the liver and pleural effusion with or without ascites.

    Pleural effusion is a frequent complication in patients undergoing hemodialysis (HD). We report a patient on HD with a novel cause of recurrent unilateral pleural effusion. A 45-year-old female patient on long-term maintenance HD presented to us with recurrent unilateral pleural effusion. She had a history of poor quality dialysis, severe anemia and severe hypertension. Despite correcting these factors and even after undergoing successful renal transplantation, she continued to have recurrent effusion. Left upper extremity venography demonstrated severe stenosis of the subclavian vein and an increased venous flow in the ipsilateral arteriovenous (AV) fistula. Ligation of the AV fistula led to dramatic resolution of the pleural effusion. Hemodialysis patients who develop unexplained pleural effusions ipsilateral to a functioning AV fistula should be investigated for stenosis in the brachiocephalic vein, particularly those patients who have had previous catheterizations of the jugular or subclavian veins on the same side as the effusion. Correcting the stenosis by venous angioplasty and/or ligation of the ipsilateral fistula can dramatically resolve the pleural effusion. A high index of suspicion is required to diagnose this complication for meaningful intervention. PMID:22237229

    An inversion method is proposed for depth profiling of the thermal effusivity from the surface temperature evolution after an excitation. Focus is on pulse heating. The effusivity profile is obtained through a Laplace inversion. The Stehfest method is implemented and we propose to use the number of elements in the Stehfest series N as a regularizing parameter. The optimum N value is defined by plotting a characteristic C curve with the norm of the solution derivative and the norm of the residues of the so-called apparent effusivity function. Examples of inversion results are given for linear and Gaussian effusivity profiles. For this purpose, we extended the formalism of thermal quadrupoles to the case of linearly varying effusivity. A statistical analysis is performed to assess the influence of noise on the inversion results. Recommendations on the thermogram minimum duration are derived therefrom. Experimental results obtained with a case-hardened steel sample show the potential of the present nondestructive approach.

    A 19-year-old man with large malignant pleural and pericardial effusions with tamponade physiology and signs of congestive heart failure presented for emergent subxiphoid pericardial window. Surgical drainage of the pericardium was complicated by a paradoxical cardiovascular collapse that failed to respond to pressors and intravenous fluids. Suspecting a pericardial perforation, a median sternotomy was performed and revealed an intact heart. The arterial pressure was promptly restored after drainage of the pleural effusion. It is proposed that, in patients presenting with tamponading pericardial and pleural effusions, drainage of the pleural effusion be given priority. The pathophysiology of low cardiac output states resulting from pericardial and large pleural effusion is discussed and the literature reviewed. PMID:27555190

    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.

    Pleural effusions are one of the rarest complications reported in patients with silicone gel filled breast implants. The silicone implants have potential to provoke chronic inflammation of pleura and subsequent pulmonary complications such as pleural effusion. Herein, we report a 44-year-old female who presented with left sided pleural effusion, six weeks after a silicone breast implantation surgery. The most common infectious, inflammatory, and malignant causes of pleural effusion were excluded with pleural fluid cytology and cultures. With recurrent effusion in the setting of recent surgery, the chemical reaction to silicone breast implants was sought and exploration was performed which revealed foreign body reaction (FBR) to silicone material. The symptoms dramatically improved after the explantation. PMID:26693375

    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

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    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. PMID:9503974

    A 90-year-old woman was admitted to our hospital in December 1993 because of dyspnea on exertion and malaise. She had been well until October 1993, when she first noticed Raynaud's phenomenon, skin tightening, digital ulceration and scarring of her hands. On physical examination, generalized edema was found, along with acrosclerosis with contracture, especially in the fingers, wrists, and elbows. Inspiratory crackles were noted. A roentgenogram of the chest and an echocardiogram revealed pulmonary fibrosis, pulmonary congestion, and massive pleural and pericardial effusions. The pleural effusion was a transudate. Progressive systemic sclerosis was diagnosed, and furosemide and isosorbide were given. The edema and pulmonary congestion resolved, but the pleural and pericardial effusions did not. Prednisolone was given, which reduced the pleural effusion but not the pericardial effusin. The pleura and the pericardium are not usually involved in progressive systemic sclerosis, and this disease rarely occurs in patients over 70 years old. To the best of our knowledge, this was one of the oldest patients with progressive systemic sclerosis. The combination of massive pleural and pericardial effusions, and the advanced age of onset make the present case unusual. PMID:8890609

    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. PMID:27246596

    The sequential cytologic and biochemical events of middle ear effusion (MEE) were studied in experimental models of serous otitis media (SOM) and purulent otitis media (POM) in chinchilla. In the SOM model, the initial appearance of neutrophils was followed by macrophages. In the POM model, neutrophils were the predominant cells in MEE and the number of neutrophils was about 100-fold higher than in the SOM model. The activity of lysozyme in MEE was higher in POM than in SOM and correlated with the number of neutrophils and mononuclear phagocytes. The results of the present study suggest that neutrophils and mononuclear phagocytes are one of the main sources for lysozyme levels in MEE during otitis media. PMID:6598270

    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. PMID:26150911

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma.A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively.To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    Primary effusion lymphoma (PEL) is a human herpes virus 8 (HHV8)-positive large B-cell neoplasm that presents as an effusion with no detectable tumor in individuals with human immunodeficiency virus infection or other immune deficiencies. PEL is an aggressive neoplasm with a poor prognosis. PEL cells show diverse morphologies, ranging from immunoblastic or plasmablastic to anaplastic. The immunophenotype of PEL is distinct, but its lineage can be misdiagnosed if not assessed thoroughly. PEL cells usually express CD45, lack B- and T-cell-associated antigens, and characteristically express lymphocyte activation antigens and plasma cell-associated antigens. Diagnosis of PEL often requires the demonstration of a B-cell genotype. HHV8 must be detected in cells to diagnose PEL. In most cases, PEL cells also harbor the Epstein-Barr virus (EBV) genome. Similar conditions associated with HHV8 but not effusion-based are called "extracavitary PELs." PELs should be differentiated from HHV8-negative, EBV-positive, body cavity-based lymphomas in patients with long-standing chronic inflammation; the latter can occur in tuberculous pleuritis, artificial pneumothorax, chronic liver disease and various other conditions. Despite their morphological similarity, these various lymphomas require different therapeutic strategies and have different prognostic implications. Correct diagnosis is essential to manage and predict the outcome of patients with PEL and related disorders. PMID:24868220

    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.

    Dengue is the most common and widespread arthropod borne arboviral infection in the world today. Recent observations indicate that the clinical profile of dengue fever is changing with neurological manifestations being reported more frequently. A 50-year-old male patient was admitted with fever and thrombocytopenia. He was diagnosed as dengue fever with positive IgM dengue serology. Patient was managed medically in the ward for seven days and observed for any complications. Fever subsided since third day of admission and platelet count started to improve; he had no complication of dengue fever and was discharged in stable condition. However, patient again came back to emergency with two episodes of generalized tonic clonic seizures followed by altered sensorium. Emergency NCCT head and later MRI brain revealed bilateral subdural effusion. Patient was managed with antiepileptic drugs and anti-oedema measures were taken. Patient showed improvement in sensorium after 48 hours of admission. Later after six weeks NCCT and MRI brain revealed complete resolution of subdural effusion. PMID:26393157

    Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the "off" state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures. PMID:15096015

She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin. PMID:19480266

    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

    A 43-year-old male with chronic kidney disease on maintenance hemodialysis presented with breathlessness, cough and right-sided abdominal pain. Examination revealed a large right-sided pleural effusion and subsequent thoracocentesis yielded an exudate. Although the fluid culture was sterile, sputum culture produced Moraxella catarrhalis. Tuberculosis was ruled out by pleural fluid analysis and pleural biopsy. Antibiotics were administered and subsequent radiograms indicated resolution of the effusion. This is a rare case of a large unilateral pleural effusion secondary to M. catarrhalis infection in a nonsmoker with no pre-existing pulmonary pathology. PMID:23393539

    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.

    A 55-year-old carpenter developed pleurisy with pleural effusion on the right side in 2000 and on the left side in 2003. No known causes of pleurisy were found. He had been occupationally exposed to asbestos during a 6-month-period in 1971 while working with roof sheets made of asbestos cement. In the literature there is evidence of asbestos being a cause of benign pleural effusion. We found it likely that the pleurisy with pleural effusion found in this patient was an occupational condition and it should therefore be notified as industrial injury. PMID:21040677

    Two rare cases of amebic pericardial effusion as a complication of amoebic liver abscess in the left lobe are described. The pericardial amebiasis should be suspected in a patient presenting with signs and symptoms of pericardial effusion with an evidence of hepatic abscess (in the left lobe) or in a patient with pericardial effusion of uncertain etiology. Aspiration of "anchovy sauce" pus from both the pericardial cavity and the liver should be regarded as confirming the diagnosis of amebic pericarditis secondary to amebic liver abcess because demonstration of Entamoeba hystolytica is seldom possible. Removal of pericardial pus and metronidazole intake were markedly effective in treating our patients. PMID:123716

    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 pleural effusions, and avoids many negative aspects of computerized tomography. Additionally, point-of-care ultrasound can 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.

    We present the case of thoracic aortic aneurysm associated with the tuberculous pleural effusion. An 82-year-old woman underwent emergency stent graft under a diagnosis of dissecting thoracic aortic aneurysm. Preoperative computed tomography revealed right pleural effusion supposed to the hemothorax caused by the dissecting aneurysm. But, the effusion was sanguineous color fluid and it was determined to result from pulmonary tuberculosis. The medical team was exposed to the pulmonary tuberculosis; fortunately no one became infected. Physicians should be aware of the possibility of an infected aortic aneurysm and prepare for pathogen transmission. PMID:27499987

    The authors present a rare case of congenital diaphragmatic Bochdalek hernia in an adult stimulating left pleural effusion. The diagnosis of left pleural effusion was made on the basis of conventional chest X-ray and ultrasonography. The definitive diagnosis of Bochdalek hernia was made by left video-assisted thoracoscopy. The patient was successfully treated operatively by conventional surgery--a combination of left thoracotomy and median laparotomy. The reported case supported the view that Bochdalek hernia in adults presents usually with atypical chronic abdominal and respiratory symptoms. Surgical treatment should best be performed, according to the authors, by competent surgeons with good command of both the thoracic and abdominal approaches to the diaphragm. PMID:21462894

    The commonly utilized phosphodiesterase type 5 (PDE5) inhibitors does not lead to satisfactory penile erection after radical prostatectomy due to lack of nitric oxide (NO) released from the damaged cavernous nerves (CNs). Of particular interest is that Icariin (ICA) has been demonstrated to increase the expression of neuronal NO synthase (nNOS) in our previous work. In this study, the efficacy and mechanisms ICA in combination with daily sildenafil for the treatment of neurogenic erectile dysfunction (ED) was investigated in a rat model of bilateral CNs injury (BCNI). Sixty male Sprague-Dawley rats injected with 5-ethynyl-2-deoxyuridine (EdU; 50 mg/kg) at newborn were used to track endogenous stem cells (SCs). Fourty-eight rats of BCNI were randomized equally into gavage feeding of vehicle, sildenafil, ICA and sildenafil+ICA, respectively. Twelve sham-operated rats received vehicle treatment and served as control. Interestingly, ICA in combination with sildenafil resulted in better erectile function and effectively preserved the penile size compared with the control and sildenafil groups (P<0.05). In addition, the numbers of nNOS-positive nerves and EdU-positive cells coexpressing Schwann cell marker S100 in the ICA-treated groups were greater compared with the control group (P<0.05). These results indicate that ICA promotes endogenous SCs to differentiate into Schwann cells, which is essential for the regeneration of nNOS-positive nerves after BCNI; on this basis, sildenafil can then improve penile engorgement through the NO-activated smooth muscle relaxation. Therefore, the combined use of ICA and daily sildenafil may be a candidate for the treatment of neurogenic ED in the future.

    Human chorionic gonadotropin (HCG) is expressed in germ cell tumors and urothelial, breast, lung and colon cancers. The aim of the study was to investigate if the determination of HCG in comparison with CEA is able to discriminate between malignant and benign effusions. Effusion and partially serum samples of 61 patients with benign (g.i., heart/kidney isnuff.) and 116 patients with malignant diseases (g.i., gynec., lung, misc., CUP) were investigated. HCG was specifically determined by an IRMA using 2 monoclonal antibodies, CEA by a conventional double Ab RIA. Cytological staining was preformed using the Pappenheim-method on cytospin preparations. Significant differences (p < 0.001) were found for HCG between benign and malignant ascitic effusions with the best discrimination at 5 IU/l (ROC) and an overall sensitivity of 31.3% (spec. vs benign eff. 93.4%) increasing in subgroups from hematol. (5.8%) < misc. (31.3%) < gynec. (32.1%) < g.i. (36%) < lung (38.1%) to CUP (50%). CEA also showed significant differences between benign and malignant total and ascitic effusions, and weaker for the pleural subgroup (cutoff 9 ng/ml) with a total sensitivity of 44.6% (sp = 100%) increasing from misc. (30.8%) < lung (47.1%) < CUP (50%) < gynec. (60%) < g.i. (60.9%). Comparative cytology and TM determinations increased the positiverate of cytology (45.2%) to 58.3% for either cytology or HCG positive cases, or to 61.6% for either cytology or CEA positive cases. For the combined determination of cytologoy and HCG and CEA, the overall TM positive rate for 33 cytology-pos. cases was 78.8%, but in 40 cytology-negative cases 37.5% for TM positive cases. In conclusion HCG is useful in ascitic > pleural effusions with high specificity (90% at 5 IU/l) but low sensitivity of 31% increasing in g.i., lung and gynecologic cases, CEA a more general TM with higher sensitivity of 45% increasing in g.i., gynecologic and lung cases (sp. 100% at 9 ng/ml) both adding significantly to cytology

    Bilateral acute depigmentation of the iris syndrome (BADI syndrome) is a new clinical entity. Young females from 20 to 45 years of age are most commonly affected. It is characterized by bilateral nontransilluminating depigmentation of the iris stroma. During the acute phase, this clinical entity also combines with red painful eye, pigmentation of the trabecular meshwork, anterior chamber flare, circulating pigment, and pigmented deposit on the endothelium cornea. At the acute stage, the symptoms are controlled with topical corticosteroid treatment. The prognosis is good. We report a 41-year-old woman presenting with BADI syndrome. PMID:21531477

    The aim of this study is to report a rare case of massive pericardial effusion as initial manifestation of hypothyroidism. A previously healthy 21-year-old female patient suddenly began presenting dyspnea at rest and lower limb edema. Routine laboratory tests performed at admission showed hypothyroidism (TSH 146.14 mUI/L) and echocardiography showed significant pericardial effusion. Therapy was instituted with levothyroxine, resulting in clinical improvement without pericardiocentesis. The patient was followed up for 1 year, with total remission of dyspnea and edema. However, she developed typical symptoms of hypothyroidism, and remained with asthenia, dyslipidemia, weight gain, and mild pericardial effusion at the end of one year, even with the optimization of the levothyroxine dose. This case highlights the need for early investigation of hypothyroidism in patients with pericardial effusion. PMID:22990643

    Recurrent pleural effusions occurring in association with immunoglobulin light chain amyloidosis and not associated with amyloid cardiomyopathy are rare. These portend an overall poor prognosis with mean survival time of approximately 1.8 months. We hereby report a case of a 59-year-old Caucasian female with recurrent pleural effusions and an ultimate diagnosis of pulmonary amyloidosis in association with plasma cell myeloma. The optimal treatment for recurrent pleural effusions in amyloidosis has not been determined; however, our patient responded to therapy with Cyclophosphamide-Bortezomib- (Velcade-) Dexamethasone (CyBorD) and had no repeat hospitalizations or recurrence of pleural effusion at four-month follow-up after initiation of therapy.

    INTRODUCTION AND OBJECTIVES Tuberculosis and cancer are the main causes of pleural effusion. Pleural involvement is associated with migration of immune cells to the pleural cavity. We sought to characterize the immunophenotype of leukocytes in the pleural effusion and peripheral blood of patients with tuberculosis or malignancy. METHODS Thirty patients with tuberculosis (14) or malignancy (16) were studied. A control group included 20 healthy blood donors. RESULTS Malignant phycoerythrin pleural effusions showed higher percentages of CD3, CD4, CD3CD45RO, and CD20CD25 lymphocytes and lower percentages of CD3CD25 and CD20HLA-DR when compared to PB lymphocytes. Compared to PB, tuberculous effusions had a higher percentage of lymphocytes that co-expressed CD3, CD4, CD3CD45RO, CD3TCRαβ, CD3CD28, and CD20 and a lower percentage of CD14, CD8 and CD3TCRγδ-positive lymphocytes. Malignant effusions presented higher expression of CD14 whereas tuberculous effusions had higher expression of CD3 and CD3CD95L. Peripheral blood cells from tuberculosis patients showed higher expression of CD14, CD20CD25 and CD3CD95L. Compared with the control cells, tuberculosis and cancer peripheral blood cells presented a lower percentage of CD3CD4 and CD3CD28-positive cells as well as a higher percentage of CD3CD8, CD3CD25 and CD3CD80-positive cells. CONCLUSIONS Tuberculous and malignant peripheral blood is enriched with lymphocytes with a helper/inducer T cell phenotype, which are mainly of memory cells. CD14-positive cells were more frequently found in malignant effusions, while CD3-positive cells expressing Fas ligand were more frequently found in tuberculous effusions. PMID:18925324

    Otitis media with effusion (OME) is a common middle ear inflammatory disease in the pediatric population. This article determines concentrations of three functionally and metabolically distinct inflammatory mediators in middle ear effusions (MEE) and corresponding plasma of children with OME. One hundred two patients (mean age, 4.9 years) with persistent OME were studied. Middle ear effusions were collected from all subjects and plasma from a subset at the time of tympanostomy tube insertion. Histamine was assayed radioisotopically, 13,14-dihydro-15-keto-prostaglandin F2 alpha (stable PGF2 alpha metabolite) by radioimmunoassay, and neutrophil chemotactic factor of anaphylaxis by modified Boyden chamber. Mean MEE levels of the mediators (39 +/- 13 ng/mL, 462 +/- 179 pg/mL, and 264% +/- 57% positive control, respectively) were markedly higher than those of corresponding plasma (0.5 +/- 0.1 ng/mL, 285 +/- 127 pg/mL, and 47% +/- 5% positive control, respectively). The mean histamine content of mucoid effusions (43.2 +/- 56.9 ng/mL) was significantly higher than that of purulent (22.5 +/- 10.5 ng/mL) and serous (17.9 +/- 16.8 ng/mL) effusions. Higher histamine levels were observed in effusions positive for Haemophilus influenzae when compared with those with other pathogenic isolates. The high concentrations of these mediators in MEE and their potential for inducing or sustaining the inflammatory process supports a role in the pathogenesis of OME. PMID:3046637

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.

    The bilateral sagittal split osteotomy is an indispensable tool in the correction of dentofacial abnormalities. The technique has been in practice since the late 1800s, but did not reach widespread acceptance and use until several modifications were described in the 1960s and 1970s. Those modifications came from a desire to make the procedure safer, more reliable, and more predictable with less relapse. Those goals continue to stimulate innovation in the field today and have helped the procedure evolve to be a very dependable, consistent method of correction of many types of malocclusion. The operative surgeon should be well versed in the history, anatomy, technical aspects, and complications of the bilateral sagittal split osteotomy to fully understand the procedure and to counsel the patient.

    Purpose: To describe a case of bilateral presumed tuberculous choroiditis which resolved promptly with a short course of antituberculous therapy. Case Report: A 44-year-old lady presented with bilateral visual loss of 8 months’duration. Considering the presence of pan-uveitis, severe macular edema, multifocal leakage on fluorescein angiography, positive tuberculin skin test, and after excluding other diseases, she underwent anti-tuberculous therapy (ATT) for disseminated choroiditis due to presumed ocular tuberculosis. She improved promptly and completely. There were no signs of relapse 18 months after completion of the treatment course. In a young patient with disseminated choroiditis and relatively short duration of symptoms, a course of ATT for 6 months may effectively treat the disease preventing relapse for a considerable period of time. Conclusion: In Presumed Tuberculous chroiditis early diagnosis is crucial for prompt and complete improvement. PMID:27413507

    ABSTRACT Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo­ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. Here is the presentation of a case of unusual location of supernumerary teeth located in between mandibular first and second molar region bilaterally.

    The aim of this study was to explore the diagnostic value of IL-31 levels in the pleural fluid and plasma to differentially diagnose tuberculous and malignant pleural effusion. We enrolled 91 cases, including tuberculous pleural effusion (TPE, n = 50), malignant pleural effusion (MPE, n = 41), other cases including pneumonia with pleural fluid, pulmonary tuberculosis and healthy people as controls. Whole blood was stimulated with the M. tuberculosis–specific antigens and plasma was collected. The multiplex bead-based cytokine immunoassay was employed to measure the levels of various cytokines. IL-31 was found to be the most prominent cytokine (P < 0.0001), and with an optimal cut-off value of 67.5 pg/mL, the sensitivity and specificity for the diagnosis of TPE were 86% and 100%, respectively. Furthermore, the tuberculosis-specific IL-31 levels in the plasma of TPE patients were higher than that of MPE patients (P = 0.0002). At an optimal cut-off value of 23.9 pg/mL, the sensitivity and specificity for the diagnosis of TPE were 92.9% and 85.7%, respectively. Ultimately, the combination of pleural fluid with the plasma tuberculosis-specific IL-31 levels improved the sensitivity and specificity to 94.0% and 95.1%, respectively. Thus, we identified a novel biomarker for the diagnosis of TPE for clinical application. PMID:26864868

    Cutaneous leiomyomas are benign smooth muscle neoplasms of the skin. They arise from vascular, arrector pili, genital, and areolar smooth muscles. The most common localizations of cutaneous leiomyomas are the extensor surfaces of the extremities and the trunk. To our knowledge, only few cases of one-sided nipple leiomyomas have been reported, but two-sided nipple leiomyomas have not been presented. For the first time, here, we report a bilateral nipple leiomyoma. PMID:23762734

    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.

  16. Compressive Bilateral Filtering.

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

    Various cytokines are presently known to be associated with the regulation of inflammatory responses. In pediatric otitis media, cytokines that correlate with various degrees of inflammation are present in middle ear effusions as inflammatory mediators. The present study was undertaken to examine the potential role of the early-response cytokines, interleukin-1beta and tumor necrosis factor-alpha, in adult otitis media. Fifty-nine adults with otitis media underwent tympanocentesis, and the effusion specimens were analyzed for the presence of both cytokines by enzyme-linked immunosorbent assay methods. Eighty-eight percent of the effusions were serous in nature. Sixty-seven percent of the patients had a known history of head and neck malignancy and radiation to the temporal bone. Twelve percent of the effusions were positive for interleukin-1beta expression, compared with 85% of effusions in children with otitis media. Eight percent of the effusions contained tumor necrosis factor-alpha, compared with 85% of those collected in pediatric otitis media. All of the specimens that contained tumor necrosis factor-alpha also contained interleukin-1beta. In the present study, there was no correlation with head and neck malignancy/radiation or the clinical degree of inflammation with the presence of either cytokine. We conclude that adult otitis media is associated with lower expression of an acute inflammatory response, as judged by the levels of interleukin-1beta and tumor necrosis factor-alpha in the effusions. Additionally, adult otitis probably represents a less severe and more chronic inflammatory state in comparison with pediatric otitis media. Further analysis of inflammatory mediators in adult otitis media is necessary to evaluate the contribution of cytokines in relation to various etiologic factors. PMID:9781987

    A safe, easy and rapid method to calculate lava effusion rates using hand-held thermal image data was developed during June 2003 at Stromboli Volcano (Italy). We used a Forward Looking Infrared Radiometer (FLIR) to obtain images of the active lava flow field on a daily basis between May 31 and June 16, 2003. During this time the flow field geometry and size (where flows typically a few hundred meters long were emplaced on a steep slope) meant that near-vertical images of the whole flow field could be captured in a single image obtained from a helicopter hovering, at an altitude of 750 m and ˜1 km off shore. We used these images to adapt a thermally based effusion rate method, previously applied to low and high spatial resolution satellite data, to allow automated extraction of effusion rates from the hand-held thermal infrared imagery. A comparison between a thermally-derived (0.23 0.87 m3 s-1) and dimensionally-derived effusion rate (0.56 m3 s-1) showed that the thermally-derived range was centered on the expected value. Over the measurement period, the mean effusion rate was 0.38±0.25 m3 s-1, which is similar to that obtained during the 1985 86 effusive eruption and the time-averaged supply rate calculated for normal (non-effusive) Strombolian activity. A short effusive pulse, reaching a peak of ˜1.2 m3 s-1, was recorded on June 3, 2003. One explanation of such a peak would be an increase in driving pressure due to an increase in the height of the magma contained in the central column. We estimate that this pulse would require the magma column to attain a height of ˜190 m above the effusive vent, which is approximately the elevation difference between the vent and the floor of the NE crater. Our approach gives an easy-to-apply method that has the potential to provide effusion rate time series with a high temporal resolution.

    Background Bilateral breast cancer (BBC) is not an uncommon entity in contemporary breast clinics. Improved life expectancy after breast cancer treatment and routine use of contra-lateral breast mammography has led to increased incidence of BBC. Our study objective was to define the epidemiological and tumour characteristics of BBC in India. Materials and Methods A total of 1251 breast cancer patients were treated during the period January 2007 to March 2015 and 30 patients were found to have BBC who constituted the study population (60 tumour samples). Synchronous bilateral breast cancers (SBC) was defined as two tumours diagnosed within an interval of 6 months and a second cancer diagnosed after 6 months was labelled as metachronous breast cancer (MBC). Analyses of patient and tumour characteristics were done in this prospective data base of BBC patients. Results Median patient age was 66 years (range 39-85). Majority of the patients had SBC (n=28) and in 12 patients the second tumour was clinically occult and detected only by mammography of the contra-lateral breast. The second tumour was found at lower tumour size compared to the first in 73% of cases and was negative for axillary metastasis in 80% of cases (24/30). Infiltrating ductal carcinoma was the commonest histological type (n=51) and majority of the tumours were ER/PR positive (50/60). Her2 was overexpressed in 13 tumours (21%). Over 70% (22/30) of patients had similar histology in both breasts and amongst them grade concordance was present in about 69% (15/22) of patients. Concordance rates of ER, PR and Her2 statuses were 83%, 80% and 90% respectively. Bilateral mastectomy was the commonest surgery performed in 80% of the patients followed by bilateral breast conservation in 13%. At the end of study period, 26 patients were alive and disease free. Median survival was 29 months (range 3-86 months). Conclusion In most patients with BBC, the second tumour is identified at an early stage than index

    Background: Medical thoracoscopy is a minimally invasive procedure used in diagnostic and therapeutic applications for pleural diseases. In this study, we describe our experience in the outcome and analysis of thoracoscopy in undiagnosed pleural effusion presenting to our center. Materials and Methods: This is a prospective study conducted over last 2 years. We performed thoracoscopy in 129 cases of undiagnosed exudative pleural effusions using rigid thoracoscope. Clinical, radiological, cyto and histopathological data of the patients were collected prospectively and analyzed. Results: The overall diagnostic yield of thoracoscopic pleural biopsy was 110/129 (85.2%) in patients with undiagnosed pleural effusion, and 19/129 (14.8%) patients remained unexplained. Histopathological diagnosis confirmed malignancy in 66.4% patients (both primary and metastatic pleural carcinoma), tuberculosis in 28.2%, others including parapneumonic effusion in 4 cases followed by multiple myeloma, lupus pleuritis, and pulmonary langerhans cell histiocytosis in one case each. Procedure-related mortality was nil. Minor complications related to the procedure include hemorrhage, subcutaneous emphysema, etc. Conclusion: Thoracoscopy is relatively a safe and well-tolerated procedure with high diagnostic accuracy in undiagnosed pleural effusions, decreasing the need of formal diagnostic thoracotomy. Every chest physician must, therefore, consider this procedure to decrease the time lag in achieving the final diagnosis and to initiate the treatment as early as possible. PMID:27625443

    The aim of this study was to review systematically the available evidence on pleurodesis for malignant effusion, focusing on the choice of the agents, route of delivery and other strategies to improve outcomes. Four electronic databases (MEDLINE, EMBASE, Web of Science and Cochrane Controlled Trials Register) were searched, reference lists checked and letters requesting details of unpublished trials and data sent to authors of previous trials. Studies of malignant pleural effusion in humans were selected with no language restrictions applied. Criteria for randomised clinical trial (RCT) eligibility were random allocation of patients and non-concurrent use of another experimental medication or device. Methodological quality evaluation of the trials was based on randomisation, blinding, allocation concealment and intention to treat analysis. A random effect model was used to combine the relative risk estimates of the treatment effects whenever pooling for an overall effect was considered appropriate. Forty-six RCTs with a total of 2053 patients with malignant pleural effusions were reviewed for effectiveness of pleurodesis. Talc tended to be associated with fewer recurrences when compared to bleomycin (RR, 0.64; 95% CI, 0.34-1.20) and, with more uncertainty, to tetracycline (RR, 0.50; 95% CI, 0.06-4.42). Tetracycline (or doxycycline) was not superior to bleomycin (RR, 0.92; 95% CI, 0.61-1.38). When compared with bedside talc slurry, thoracoscopic talc insufflation was associated with a reduction in recurrence (RR, 0.21; 95% CI, 0.05-0.93). Strategies such as rolling the patient after instillation of the sclerosing agent, protracted drainage of the effusion and use of larger chest tubes were not found to have any substantial advantages. Talc appears to be effective and should be the agent of choice for pleurodesis. Thoracoscopic talc insufflation is associated with fewer recurrences of effusions compared with bedside talc slurry, but this is based on two small studies

    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

    Spontaneous bacterial empyema (SBEM), a rare infectious complication among liver cirrhosis patients, is characterized by infection in the presence of pleural effusion without evidence of pre-existing pneumonia. The prevalence of SBEM in cirrhotic patients with hydrothorax is about 13%. However, it has previously not been reported in medical literature in patients with nephrotic syndrome. The most common microorganism identified is Escherichia coli, followed by Streptococcus species, Enterococcus species, Klebsiella pneumoniae, and Pseudomonas stutzeri. We present a patient with a history of nephrotic syndrome caused by membranous nephropathy, who received steroids and cyclophosphamide. He developed bilateral SBEM due to Aeromonas hydrophila and E. coli, which were isolated from the left- and right-side pleural fluid, respectively. The detailed clinical course, treatment, and outcome are described. PMID:16457891

    Pneumocephalus is collection of gas or air within the cranial cavity, commonly associated with trauma, cranial surgery, air embolism, open meningomyelocele; and rarely as a result of central nervous system infections. Asymptomatic pneumocephalus usually recovers spontaneously within few days. Untreated pneumocephalus can progress to tension pneumocephalus, manifesting as severe headache, dizziness, cranial nerve palsy, mental changes, seizure and disorientation. Herein, we report a rare case of pneumocephalus in a 9-month infant with subdural effusion following infection of nasal septum and otomastoiditis. There was no sign of meningitis but CThead showed communication of intracranial dura mater across widened foramen caecum with pre-nasal space, and bilateral otomastoiditis with erosion of anterior and lateral wall of right mastoid bone. The patient was treated successfully and discharged without sequelae. PMID:27504559

    Posterior sternoclavicular dislocations are a rare injury, representing <5% of all sternoclavicular dislocations and 1 in 1600 shoulder girdle injuries. Proper imaging with computed tomography and prompt diagnosis are essential steps in preventing potentially lethal complications observed in approximately 3% of all posterior sternoclavicular dislocations. Surgical treatment is necessary if closed reduction fails. With the medial clavicular epiphysis being the last to close (between ages 22 and 25), children and adolescents typically present with epiphyseal fractures rather than joint dislocations. If closed reduction fails, open reduction and internal fixation (ORIF) should be considered in fractures, whereas complex reconstructions with tendon graft procedures have been recommended for joint dislocations. This article presents a case of a traumatic bilateral posterior sternoclavicular dislocation due to an epiphyseal fracture in a 15-year-old boy. To our knowledge, this is the first reported case of a bilateral posterior sternoclavicular dislocation. Attempted closed reduction failed with redislocation after 2 days. The patient subsequently required ORIF. This article describes our technique with anterior retraction of the medial clavicle, closure of the posterior periosteum, and ORIF using nonabsorbable sutures. Postoperative shoulder mobilization was started on day 1. At final follow-up, the patient was completely asymptomatic. PMID:20608625

    Pleural effusion is a ubiquitous complication in hemodialysis (HD) patients. Common etiologies of pleural effusion in this patient group are heart failure, volume overload, parapneumonic effusion, tuberculotic pleuritis, and uremic pleuritis. Although thoracentesis is a useful diagnostic method of pleural effusion, empirical reduction of the dry weight is often attempted without thoracentesis because pleural effusion is commonly caused by volume overload and responds to the dry-weight reduction. However, this empiricism has a risk of overlooking or delaying the diagnosis of potentially fatal etiologies that need specific treatments. We report an 86-year-old human immunodeficiency virus (HIV)-negative male on HD with primary effusion lymphoma (PEL), a large-cell non-Hodgkin lymphoma presenting with characteristic lymphomatous effusions in the absence of solid tumor masses, which is in association with human herpes virus 8 (HHV8) infection in immunocompromised individuals. The patient presented with left-sided pleural effusion. This is the first case report of PEL developing in a patient receiving HD. Thoracentesis and cytological analysis of the effusion was key to the diagnosis. We also review the literature regarding pleural effusion in HD patients. Further, we examine Kaposi's sarcoma herpes virus/HHV8-negative effusion-based lymphoma, a newly proposed distinct lymphoma that clinically and cytomorphologically resembles PEL, because it can be cured without chemotherapy. This report may arouse clinicians' attention regarding the importance of evaluation for pleural effusion in HD patients, especially when the effusion or symptoms associated with pleural effusion are refractory to volume control.

    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

    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

    Chylopericardium after cardiac surgery is rare, and there are few reports of its occurrence after aortic valve surgery. Chylous pericardial effusion 4 months after aortic valve replacement for endocarditis is highly unusual. Herein, we report the case of a 54-year-old man who had undergone bioprosthetic aortic valve replacement because of endocarditis and valvular dysfunction. Two months later, he underwent pericardiocentesis twice because of large pericardial effusions consisting of pinkish white fluid with predominant lymphocytes. Four months after valve replacement, he presented with recurrent effusion consistent with early tamponade, and a pericardial window was created. At surgery, 1,500 cc of milky white fluid was recovered, and the diagnosis of chylopericardium was made. Postoperative high-volume drainage prompted thoracic duct ligation, which was curative.

    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.

    A novel quasi-physical edge detection model is presented. The model, referred to as the effusion-evaporation model (EEM), is inspired by the natural phenomenon that the water effusing from the ground evaporates in the sunshine and leaves a wire like water stain on the ground surface, which reflects the physiognomy of the terrain. Based on the simulation of water effusing and evaporating, an EEM regards the complement of gradient magnitude image as a three-dimensional terrain, and the concave regions, which contain the residual water in the evolution final state, are used to determine the edges. Subjective and objective comparisons are performed on the proposed algorithm and two conventional edge detectors, namely Canny and LoG. The comparison results show that the proposed method outperforms Canny and LoG detectors for the real images and the standard test images with Gaussian noise.

    Introduction Langerhans cell histiocytosis (LCH) is a proliferative disorder of histiocytes in multiple organs. Langerhans cell histiocytosis involves bones, skin, lung and other organs. Case Presentation This study describes a seven-month-old Iranian girl who presented with skin rash and cervical lymphadenopathy. Langerhans cell histiocytosis was suspected when it was associated with anemia, splenomegaly and lytic bone lesions. A skin biopsy confirmed the diagnosis of Langerhans cell histiocytosis. During hospitalization, the patient looked ill with respiratory distress. A chest X-ray showed a ground glass view, and echocardiography showed moderate pericardial effusion. Conclusions Pericardial effusion was a rare finding in this case of Langerhans cell histiocytosis. Pericardial effusion in Langerhans cell histiocytosis, which is an unusual presentation, should be considered when the patient experiences respiratory distress. PMID:27621925

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation has published a supplement to this issue of Otolaryngology-Head and Neck Surgery featuring the updated "Clinical Practice Guideline: Otitis Media with Effusion." 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. PMID:26833645

    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.

    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. PMID:24698396

    Primary pericardial synovial sarcoma is an extremely rare disease with a dismal prognosis. Its main presenting symptoms are a large pericardial effusion, signs of cardiac tamponade, and visualization of a pericardial mass on echocardiography. However, the systemic symptoms of fever, cough, and night sweats may present a clinical picture without any apparent pericardial mass on diagnostic imaging, potentially impeding the diagnosis. We report the case of a 34-year-old patient with fever and recurrent pericardial effusion for 2 years, who was diagnosed with primary pericardial synovial sarcoma after 2-year follow-up echocardiography.

    The diffusion and effusion of hydrogen in hydrogenated microcrystalline silicon films deposited in an electron cyclotron resonance reactor were studied for various deposition temperatures T{sub s}. For deposition temperatures below 250 C, hydrogen effusion is found to be dominated by desorption of hydrogen from internal surfaces followed by rapid out-diffusion of H{sub 2}. Higher substrate temperatures result in an increased hydrogen stability suggesting the growth of a more compact material. For this latter type of samples, a hydrogen diffusion coefficient similar as in compact plasma-grown a-Si:H films is found despite a different predominant bonding of hydrogen according to infrared absorption.

    Multiple myeloma is a clonal B-cell malignancy, characterised by proliferation of plasma cells and secretion of paraproteins. These plasma cells accumulate predominantly in the bone marrow; rarely, they invade other areas, especially the thorax. Myeloma presenting with a pleural effusion is rare and reported in only 6% of patients with myeloma. Such patients generally present late and have a poor prognosis. Here, we describe a patient presenting with a lung mass, renal failure and a massive unilateral pleural effusion due to multiple myeloma who was treated successfully. PMID:27520995

    Visceral leishmaniasis (VL) is usually characterized by splenomegaly, pallor and fever. Pleural effusion is an uncommon feature of this disease, which is encountered in immunocompromised patients. Here, we report a case of VL with pleural effusion in an immunocompetent patient. Pulmonary symptoms in VL are usually related to bacterial lung infection, vagal nerve compression by splenomegaly, and hypoalbuminaemia with mild pulmonary edema. Our patient presented with cough and chest pain. The clinical features of this case were baffling since they mimicked that of pulmonary tuberculosis. This case report emphasizes the need to recognize the diverse nature of presentation of this curable yet fatal infectious disease. PMID:24669085

    Background/Aims To evaluate the characteristic properties of laryngopharyngeal reflux (LPR) and gastroesophageal reflux (GER) in children with otitis media with effusion (OME) using 24-hour multichannel intraluminal impedance combined with dual-probe (pharyngeal and esophageal) pH-metry. Methods Children aged 7–10 years of age with OME underwent 24-hour multichannel intraluminal impedance pH-metry. The upper pH sensor was situated 1 cm above the upper esophageal sphincter, and the lower pH sensor was placed 3–5 cm above the lower esophageal sphincter. Parents were asked to complete the gastroesophageal reflux assessment of symptoms in a pediatrics questionnaire. Results Twenty-eight children were enrolled; LPR was detected in 19 (67.9%) children. The criteria of the LPR diagnosis was the presence of at least one supraesophageal episode with a pH < 5.0 and a change in the pH value measured from the initial level at the upper sensor of > 0.2. In total, 64 episodes were observed. Assessment of all LPR episodes showed the presence of 246 episodes in the entire study. A considerable predominance of weakly acidic episodes (87.8%) was noted; there were 6.5% acidic episodes, and weakly alkaline episodes reached 5.7%. Pathological GER was noted in 10 (35.7%) subjects. Acid GER was detected in 8 children, 2 of whom demonstrated non-acidic reflux. In the LPR-negative patients, no pathological GER was confirmed with the exception of a single case of non-acidic reflux. Conclusions LPR was frequently noted in the group of children with OME, and it might be an important risk factor in this common disease. PMID:27193974

    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

    Introduction 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. Methods and analysis 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.

    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 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

    We assayed 38 middle ear effusions from 23 children aged 4-13 years (mean 7) undergoing tympanostomy tube placements. All fluid was assayed for tumor necrosis factor (TNF) alpha, interleukin (IL) 1beta, IL-8, and IL-10. Cytokine concentrations were measured by means of an enzyme-linked immunosorbent assay. Detectable levels of IL-1beta, IL-8, and IL-10 were found in all of the effusions. TNF-alpha was detected in 18 of the middle ear effusions (47.4%). The mean concentration of TNF-alpha, IL-1beta , IL-8, and IL-10 was, respectively, 0.423 +/- 1.39, 30.58 +/- 68.7, 7001.9 +/- 6743, and 56 +/- 58.7 pg/ml. There was a strong, statistically significant correlation between the concentrations of TNF-alpha and IL-1beta (r = 0.87, P = 0.001) and between IL-1beta and IL-8 (r = 0.53, P = 0.001). There was no correlation between the concentrations of IL-10 and other cytokines examined or between tympanic membrane pathology and the concentrations of TNF-alpha, IL-1beta , IL-8, or IL-10. The presence of IL-10 in middle ear effusions may be one of the causes of a lack of clinical features of acute inflammation and may lead to a chronic inflammatory state. PMID:10993552

    Metastases from carcinomas of unknown primary site (CUP) in serous effusion are a common clinical problem. Immunocytochemistry was applied as an adjunct to the cytological diagnosis of metastatic carcinomas in serous effusions. Subjects of this study were 118 pleural, 53 peritoneal, and 9 pericardial effusions from 180 patients routinely investigated in the Institute of Cytopathology. Specimens were primarily stained according to Papanicolaou (Pap). The avidin-biotin-complex method (ABC) was secondarily applied for the visualization of immunologic reactions. We have used a panel of six monoclonal antibodies (CK 5/6, CK 7, CK 20, CA 125, TTF-1, and cdx 2) so as to identify the primary tumor site of metastatic carcinoma cells in serous effusions. Applying an algorithm of immunocytochemical marker constellations, we were able to correctly diagnose primary tumor sites in 86 of 101 (85.1%) patients with CUP syndromes. The best result was achieved for the identification of metastatic carcinomas of the ovaries (94.7%) and the lungs (88.1%). We established an algorithm comprising six immunocytochemical markers that enabled a correct diagnosis of primary tumor sites in 85.1%. The panel studied could be useful in diagnostic routine for the identification of primary tumors of unknown origin metastatic to the serous membranes. PMID:16240395

    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 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

    Background Tuberculous pleural effusion (TPE) exhibits different characteristics according to pleural fluid cellular predominance or whether the pleural fluid is free-flowing or loculated. However, its categorization based on either of these factors alone may be insufficient to properly reflect the heterogeneous manifestation of TPE. We evaluated the characteristics of the four TPE groups classified according to cellular predominance and whether the fluid is free-flowing or loculated. Methods A cohort of 375 patients with TPE was retrospectively reviewed. Clinical, radiological, and laboratory findings were compared between neutrophilic and lymphocytic TPE, and between free-flowing and loculated effusion for both neutrophilic and lymphocytic TPE. Results Lymphocytic TPE and neutrophilic TPE were observed in 336 (90%) and 39 (10%) patients, respectively. Pleural fluid loculation was present in 36% and 31% of the patients in the lymphocytic and neutrophilic groups, respectively. A few parameters of the laboratory findings between neutrophilic and lymphocytic TPE patients showed significant differences. However, these significant differences were prominently observed when comparing free-flowing and loculated subgroups of the respective neutrophilic and lymphocytic groups. Pleural fluid pH, lactate dehydrogenase, and adenosine deaminase levels were significantly different among the four subgroups. The neutrophilic loculated subgroup exhibited the most intense pleural inflammation and the highest mycobacterial yields when compared to the other subgroups. However, the percentage of neutrophils in the pleural fluid was not positively associated with the probability of culture-positive effusion. Conclusions The heterogeneous manifestation of TPE would be better characterized by using a classification system based on combined pleural fluid cellular predominance and loculation, with the neutrophilic loculated subgroup contributing to most of the clinically significant

    We describe 12 patients with simultaneous bilateral spontaneous pneumothorax (SBSP). They represent 4 percent of patients with spontaneous pneumothorax seen at our hospital from 1971 to 1990. Five of the 12 had no underlying lung disease. In the seven remaining patients, SBSP was secondary to histiocytosis X, lymphangioleiomyomatosis, osteogenic sarcoma with pleural and pulmonary metastases, Hodgkin's disease, mesothelioma, cystic fibrosis, or miliary tuberculosis. Nineteen of the 56 patients with SBSP (34 percent) described in the literature (this series included) had pulmonary disease related to disorders of cells of mesenchymal origin. Emphysema and bullous lung disease were not associated with SBSP. Long-term prognosis was a function of pulmonary status. Four of the patients described herein died during the period reviewed. All suffered from severe underlying disease. In no case was SBSP the main cause of death. With timely treatment, the short-term prognosis is benign even for patients with underlying lung disease. Surgical pleurectomy should be attempted early, especially in SBSP secondary to underlying lung disease. PMID:8162740

    Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    Acute spontaneous compartment syndrome of the forearm is rarely reported in the literature. It is typically associated with trauma or thromboembolism in the acute setting and repetitive exertional stress in the chronic setting. However it is rare for it to present bilaterally with no apparent underlying cause. We report the case of a young 31-year-old lady who presented to our Emergency Department with bilateral compartment syndrome of the forearm. Her presenting complaints included acute severe pain and swelling of the forearms bilaterally, with a decreased range of movement of the wrist and fingers. She also complained of numbness in all fingers. She had no history of recent trauma and ultrasound scans showed no evidence of vascular compromise. Past medical history was notable only for idiopathic hypertension and coeliac disease. The patient was taken to theatre urgently where flexor and extensor compartments and carpal tunnel were decompressed. Pronator Teres was found to be dusky initially but turned pink after decompression. All other muscles were normal. An interesting fact of this case was that combination of the high compartment pressures and anaesthetic related hypotension caused the forearm pulses to become impalpable at induction, these returned intra-operatively. The patient has been seen in the outpatient department following discharge. She is well apart from some mildly reduced grip strength in her right hand likely due to carpal tunnel decompression. No cause was found for the scenario after extensive medical investigation. PMID:24641749

    Purpose. To report two persons with acute, bilateral, and simultaneous angle closure glaucoma in pseudophakia secondary to uveal effusions induced by administration of chlorthalidone. Methods. Case reports. Results. Bilateral shallow anterior chambers and high intraocular pressure with decline in visual acuity were reported in two patients within days of intake of chlorthalidone for systemic hypertension. Gonioscopy confirmed appositional angle closure while choroidal detachment and ciliochoroidal detachment were revealed on ultrasonographic studies. Discontinuing chlorthalidone and institution of aqueous suppressants to reduce IOP and cycloplegics reversed angle closure and glaucoma. Conclusions. Reports of angle closure glaucoma in pseudophakic eyes induced by idiosyncratic reaction to chlorthalidone confirms that osmotic changes in the crystalline lens has no role in the pathogenesis of drug induced glaucoma and reaffirms that glaucoma is secondary to ciliochoroidal detachment and ciliary body rotation and edema.

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.

    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

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

    18 patients with malignant effusions were treated with continuous intraperitoneal, intrapleural, or intrapericardial infusion of methotrexate (MTX) 30 mg/m2 per d combined with simultaneous intravenous administration of leucovorin at a dose rate calculated to yield an equimolar concentration in the serum. In the serum the geometric mean steady-state MTX concentration was 0.95 microM, whereas it was 24 microM in the peritoneal, 213 microM in the pleural, and 434 microM in the pericardial cavities. Mean clearance was 6.6 ml/min from the peritoneal cavity, 2.6 ml/min from the pleural cavity, and 0.14 ml/min from the pericardial cavity. Leucovorin provided sufficient protection to allow the duration of infusion to be escalated from 24 to 120 h before myelosuppression was encountered. Marrow thymidylate synthetase activity was inhibited by an average of 46% compared to 86% inhibition in malignant cells in the effusions. Flow cytometric analysis showed no perturbation of the cell cycle phase distribution of marrow cells. All eight of the evaluable patients have responded: three received no other form of therapy, five also received systemic hormonal or chemotherapy. This study demonstrated that tumors confined to third space body fluids can be given very high concentration x time exposures to MTX with minimal systemic toxicity. PMID:6970753

    BACKGROUND Erdheim-Chester disease is a rare non-Langerhans-cell histiocytosis of unknown etiology with multi-organ involvement. CASE REPORT A 19-year-old woman presented with orthopnea, severe fatigue, bilateral exophthalmos, and gradual loss of vision. She had anemia and mild leucocytosis related to chronic illness. Marked left side pleural effusion and massive pericardial effusion with bilateral hydronephrosis were detected by plain X-ray, echocardiography, and computed tomography, respectively. Retro-orbital tissue and bone marrow biopsy revealed histiocytic infiltration, which was CD68-positive and CD1a-negative. CONCLUSIONS This report describes the first case presentation of Erdheim-Chester disease in our country. This case report may advance our understanding of an orphan disease. Our patient's young age and stable clinical status may allow long-term follow-up of treatment results. PMID:27237445

    Chylous ascites and coexistent chylothorax is a rare but important complication following retroperitoneal abdominal surgery. We report a 70-year-old male who developed gradual abdominal distension, chest tightness, and dyspnea five months after having an uncomplicated aortobifemoral bypass performed. Physical examination was consistent with a large right sided effusion and ascites which were confirmed by computed tomography. Thoracentesis yielded an opaque milky fluid with analysis consistent with a chylothorax with a paracentesis revealing fluid that was similar in both appearance and biochemistry. The patient failed initial conservative management so a chest tube was placed followed by chemical pleurodesis. We review the literature of the pathophysiology and treatment approach to such a pleural effusion. PMID:26635989

    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. PMID:19889319

    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

    Pleurodesis is commonly indicated for symptom relief in patients with malignant pleural effusions. A number of factors may influence pleurodesis outcome, but whether tumor type is one of them is a matter of debate. This study investigates the impact of tumor type on the efficacy of bedside doxycycline and thoracoscopic talc poudrage pleurodesis in order to determine which patients may benefit most from these procedures. A retrospective study of 138 and 450 doxycycline and talc poudrage pleurodesis procedures, respectively, evaluated their overall successes and failures, according to primary tumor types. In addition, a logistic regression model addressed whether the pleurodesis outcome in different tumor types was influenced by or attributable to pleural tumor burden. In the talc group, patients with lung cancer and mesothelioma had significantly lower complete response rates (63 and 61%, respectively) as compared with breast (77%) and other metastatic effusions (74%, p = 0.012). In the doxycycline group, the data followed the same trend in that complete response rates were lower in patients with lung carcinomas (31%) than in those with breast cancer (54%) or metastases from other primary sites (74%, p = 0.001). The regression analysis showed pleural burden and tumor type as independent predictors of pleurodesis failure in the talc group. The tumor type involving the pleural surfaces influences the success of a pleurodesis, regardless of the sclerosing agent used. Malignant effusions due to mesothelioma and lung cancer are particularly prone to a failed procedure. PMID:21331598

    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.

    Levels of cytokines, interleukin (IL)-1 alpha, IL-1 beta, tumor necrosis factor (TNF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) were investigated in samples of the middle ear effusions (MEEs) from 144 ears with otitis media with effusion (OME) by enzyme-linked immunosorbent assay, followed by cytologic analysis. Middle ear effusions of the acute purulent type contained a significantly higher concentration of cytokines compared with normal control sera (p < .001). Cytokines were observed at lower levels in MEE in adults than in children. Tests of children at the chronic stage of MEE showed higher levels of TNF than IL-1 and GM-CSF. Meanwhile, IL-1 beta showed significantly higher concentrations in acute purulent types than in serous and mucoid types (p < .01). In cytologic analysis, the mean level of IL-1 beta was significantly higher in the neutrophil-rich group than in other groups (p < .05). Cytokines possess several biologic properties, some of which are associated not only with acute otitis media but also with chronic otitis media. This study showed that cytokines, especially IL-1 beta, contribute to infiltration into the middle ear by inflammatory cells. This implies that the persistent presence of cytokines in MEE could be a factor in prolonged OME. PMID:1416648

    Primary effusion lymphoma (PEL) is a rare and aggressive lymphoma that arises in the context of immunosuppression and is characterized by co-infection with Epstein–Barr virus (EBV) and human herpesvirus-8/Kaposi sarcoma-associated herpesvirus (HHV-8/KSHV). It was originally described as arising in body cavity effusions, but presentation as a mass lesion (extracavitary PEL) is now recognized. Here, we describe a case of PEL with an initial presentation as an intravascular lymphoma with associated skin lesions. The patient was a 53-year-old man with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) who presented with fevers, weight loss and skin lesions concerning for Kaposi sarcoma (KS). A skin biopsy revealed no evidence of KS; however, dermal vessels contained large atypical cells that expressed CD31 and plasma cell markers but lacked most B- and T-cell antigens. The atypical cells expressed EBV and HHV-8. The patient subsequently developed a malignant pleural effusion containing the same neoplastic cell population. The findings in this case highlight the potential for unusual intravascular presentations of PEL in the skin as well as the importance of pursuing microscopic diagnosis of skin lesions in immunosuppressed patients.

    Achondroplasia is the most common skeletal dysplasia and it combines various complications with normal longevity. Hearing disturbance due to otitis media or an ossicular anomaly is one of the most common complications. Conductive hearing loss is suggested as the most common form of hearing loss. Temporal bone and middle ear structures are distorted in achondroplasia because of rotational change of the skull base. Authors experienced a case of an achondroplastic patient with bilateral hearing disturbance. We faced making a potential mistake during the previous operation but a favorable postoperative result occurred. Our experience could be helpful to other clinicians who face achondroplastic patients.

    Interactions of clinical laboratory parameters with trace elements in knee-joint effusions might turn out to be potential diagnostic tool, increasing our pathophysiological understanding and knowledge on knee-joint effusions. Thus, the 11 clinical laboratory parameters, total protein, albumin, glucose, lactate dehydrogenase, uric acid, pH, rheumatoid factor, antistreptolysin, C-reactive protein, leukocyte, and erythrocyte counts were determined in 39 osteoarthritic knee-joint effusions and in corresponding sera. Additionally, concentrations of the 17 trace elements barium, beryllium, calcium, cadmium, cesium, copper, lanthanum, lithium, magnesium, molybdenum, lead, rubidium, antimony, tin, strontium, thallium, and zinc in both effusions and corresponding sera were quantified by inductively coupled plasma-mass spectrometry. Concentrations of most laboratory parameters in synovial fluid were within the normal ranges for serum. However, concentrations of total protein and albumin in effusions were distinctly lower than in sera of healthy adults. Results for rheumatoid factor, antistreptolysin, and C-reactive protein in the effusions were below their corresponding threshold values for serum. An indicator for inflammation, the leukocyte count had a median < 6.3 G/L. The erythrocyte count (median: < 0.06 T/L) revealed a very low presence of red blood cells in the effusions. Total protein concentrations and lactate dehydrogenase activity in the effusions correlated positively with effusion copper (r = 0.61 and 0.66) and effusion zinc (r = 0.71 and 0.49). For cesium, a negative correlation in both sera (r = -0.44) and effusions (r = -0.44) with LDH activity could be established. Concentrations of rubidium, strontium, and cesium responded to albumin concentrations in sera and in effusions, establishing an inverse correlation. All other trace elements showed no or only weak associations with the clinical laboratory parameters determined. Although distinct relationships

    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.

    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. PMID:27374670

    Joint effusion has been associated with temporomandibular joint (TMJ) pain but can only be diagnosed by magnetic resonance imaging (MRI). For screening of patients with suspected effusion a simple and less expensive method would be desirable. We recorded joint sounds during jaw opening and closing movement from 34 TMJs with internal derangement (ID). Seventeen joints had joint effusion seen on MRI. Spectrograms of the sounds were displayed as waterfall plots showing profiles of the consecutive Hamming windows. If the profiles were similar, as judged by initial evaluation, the displayed pattern was classified as stable. If some profiles were distinctly deviating in their pattern, this was classified as unstable. Joints with effusion showed unstable sound pattern more often than joints without effusion (P < 0.001). It was concluded that TMJ sound analyses have a potential to identify joints with effusion based on their unstable sound pattern. PMID:11856395

    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.

    Tuberculous pleuritis is a common manifestation of extrapulmonary tuberculosis and is the most common cause of pleural effusion in many countries. Conventional diagnostic tests, such as microscopic examination of the pleural fluid, biochemical tests, culture of pleural fluid, sputum or pleural tissue, and histopathological examination of pleural tissue, have known limitations. Due to these limitations, newer and more rapid diagnostic tests have been evaluated. In this review, the authors provide an overview of the performance of new diagnostic tests, including markers of specific and nonspecific immune response, nucleic acid amplification and detection, and predictive models based on combinations of markers. Directions for future development and evaluation of novel assays and biomarkers for pleural tuberculosis are also suggested. PMID:18448504

    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. PMID:25528974

    We investigated the treatment and prognosis of pleural effusion (PE) in multiple myeloma (MM) patients. From June 2005 to December 2013, 296 MM patients participated in this study. There were 23 PE patients, including 11 men and 12 women, with a median age of 56.8 years (range 37-68 years). A diagnosis of PE was based on physical examination, chest X-ray or computed tomography, and pleural fluid analysis. All patients demonstrated myeloma cells in the pleural fluid, and six patients were positive for PE M protein. PE patients received bortezomib combined with other drugs. Only one patient demonstrated a complete response; 10 patients showed partial responses, and 12 patients developed progressive disease and died. MM linked with myelomatous PE is associated with a poor prognosis. Myelomatous PE is likely a late manifestation of the natural history of MM or an expression of the aggressive behavior of the disease. PMID:26273384

    An 80-year-old man presented because of superficial head trauma sustained after falling from bed. On review of systems, he reported worsening dyspnea on exertion, nonproductive cough, and weight loss over the preceding 2 to 3 months. There was no report of chest pain or leg swelling. He had a past medical history of hypertension, coronary artery disease, subclinical hypothyroidism, and renal cell carcinoma treated with partial right nephrectomy approximately 1 year before this presentation. Two months earlier he had been evaluated in the dermatology clinic for painful, dystrophic fingernails. At that time he was diagnosed with acropachy with onycholysis and suspected superinfection, and after failing to improve with vinegar soaks and topical antimicrobials, he underwent surgical nail removal on the second and fourth digits of the right hand. Histological examination of the operative specimens revealed dystrophic nails with negative fungal stains. His medications included levothyroxine, hydrochlorothiazide, and clopidogrel. He had never smoked and had done clerical work until retirement. He was originally from Colombia. PMID:27157230

    Pleural effusion is a known entity in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT); however, the incidence, risk factors, and morbidity-mortality outcomes associated with pleural effusions remain unknown. We retrospectively evaluated pleural effusions in 618 consecutive adult patients who underwent allogeneic HSCT from January 2008 to December 2013 at our institution. Seventy one patients developed pleural effusion at a median of 40 days (range, 1 - 869) post-HSCT with the cumulative incidence of 9.9% (95% CI, 7.7 - 12.5%) at 1 year. Infectious etiology was commonly associated with pleural effusions followed by volume overload and serositis type chronic GVHD. In multivariate analysis, higher comorbidity index (P = 0.03) and active GVHD (P = 0.018) were found to be significant independent predictors for pleural effusion development. Higher comorbidity index, very high disease risk index, ≤7/8 HLA matching, and unrelated donor were associated with inferior overall survival (OS) (P < 0.03). More importantly, patients with pleural effusion were noted to have poor OS in comparison to patients without pleural effusion (P < 0.001). Overall, pleural effusion is a frequently occurring complication after allogeneic HSCT, adding to morbidity and mortality and hence, early identification is required. Am. J.
