RESUMO
BACKGROUND: Upper-lung field pulmonary fibrosis (upper-PF), radiologically consistent with pleuroparenchymal fibroelastosis (PPFE), was reported to develop in patients with a history of asbestos exposure and tuberculous pleurisy, indicating that chronic pleuritis is correlated with upper-PF development. Round atelectasis reportedly emerges after chronic pleuritis. This study aimed to clarify the association between round atelectasis and upper-PF. METHODS: We examined the radiological reports of all consecutive patients with round atelectasis between 2006 and 2018 and investigated the incidence of upper-PF development. RESULTS: Among 85 patients with round atelectasis, 21 patients (24.7%) were confirmed to finally develop upper-PF lesions. Upper-PF was diagnosed after round atelectasis recognition in more than half of the patients (13/21, 61.9%), whereas upper-PF and round atelectasis were simultaneously detected in the remaining 8 patients. At the time of round atelectasis detection, almost all patients (19/21, 90.5%) had diffuse pleural thickening and round atelectasis was commonly observed in non-upper lobes of 19 patients (90.5%). Fourteen patients had round atelectasis in unilateral lung, and the remaining 7 patients had round atelectasis in bilateral lungs. Among all 14 patients with unilateral round atelectasis, upper-PF developed on the same (n = 11) or both sides (n = 3). Thus, upper-PF emerged on the same side where round atelectasis was present (14/14, 100%). The autopsy of one patient revealed a thickened parietal-visceral pleura suggestive of chronic pleuritis. Subpleural fibroelastosis was also observed. CONCLUSIONS: Upper-PF occasionally develops on the same side of round atelectasis. Upper-PF may develop as a sequela of chronic pleuritis.

BACKGROUND: Pleural biopsies for investigating the causes of pleurisy are performed through modalities including needle biopsies, local anesthetic thoracoscopic procedures, and surgery (video-assisted thoracoscopic surgery and open thoracotomy). To date, there have been no large-scale nationwide epidemiological studies regarding pleurisy diagnosed via surgical pleural biopsy. This study examined the epidemiology of pleurisy diagnosed via surgical pleural biopsy in a Japanese nationwide administrative database. METHODS: We evaluated Japanese Diagnosis Procedure Combination data of 24 173 patients who underwent video-assisted thoracoscopic surgery or open thoracotomy and received a diagnosis of pleurisy between April 2014 and March 2020. In addition to pleurisy diagnoses, the patients' clinical information, including age, sex, smoking status (pack-years), dyspnea grade, length of in-hospital stay, and comorbidities, were extracted from the dataset. RESULTS: This study included data from 1699 patients. The most frequent causes of pleurisy were neoplastic diseases (55.9%; malignant mesothelioma 22.5%, lung cancer 15.7%, lymphoma 2.5%), followed by infectious diseases (24.0%; tuberculosis 16.2%, parapneumonic pleural effusion 3.6%, empyema 3.5%, nontuberculous mycobacteriosis 0.5%), collagen vascular diseases (2.8%; rheumatoid arthritis 1.3%, immunoglobulin G4-related diseases 0.7%, systemic lupus erythematosus 0.3%), and paragonimiasis (0.1%). CONCLUSIONS: Neoplastic diseases, including malignant mesothelioma and lung cancer, were frequently and accurately diagnosed as pleurisy via surgical pleural biopsy. The next leading cause was infectious diseases such as mycobacterial infections. Physicians should consider performing surgical biopsy in light of the knowledge regarding the etiology of pleurisy when a definitive diagnosis cannot be made via needle pleural biopsy.

This study determined the prevalence of fibrinous pericarditis and its correlation with other pluck lesions in 658 batches of pigs from 236 intensive farms located in Northern Italy over a 12-month period. All pigs were slaughtered at 170 kg, and a total 57,943 plucks (approximately 90 pigs/batch) were individually assessed for the presence of fibrinous pericarditis, pneumonia, pleuritis, and liver milk spots. There was no seasonal variation in the prevalence of plucks with fibrinous pericarditis and annual mean prevalence was 5.6% (range, 0-26.3% at batch level; median, 4.71%). Farm of origin, evaluated as a random effect, accounted for 17.7% batch variation. Batches with a high prevalence of fibrinous pericarditis (≥7.7%) had higher prevalences of pleural, pulmonary, and liver lesions than those with low-middle prevalence of pericarditis; high prevalence of pericarditis was predictive of pluck lesions (P < 0.001). There was a highly significant association between fibrinous pericarditis and severe pleuritis, and 55% of plucks with the highest score for pleuritis also had ongoing fibrinous pericarditis, with a positive correlation at batch level (r2 = 0.52; P < 0.001). The co-existence of pericarditis and pleuritis (73.5% of all pericarditis cases) suggests that pleuritis plays a role in the pathogenesis of pericarditis. Based on the prevalence fibrinous pericarditis, and the role of pleuritis as a potential comorbidity, abattoir data on pluck lesions with accompanying farm history, could aid the interpretation and management of on-farm health problems, and inform diagnostic protocols.

OBJECTIVE: Pleurisy in pigs has economic impacts in the production stage and at slaughter. This study sought to establish if some micro-organisms can be found in high numbers in lungs with pleurisy by assessing batches of pigs at an abattoir in Queensland Australia. DESIGN: Samples of lung (including trachea/bronchus and lymph nodes) from a maximum of 5 pleurisy affected pigs were collected from 46 batches of pigs representing 46 Queensland farms. PROCEDURE: Pleurisy-affected lung areas were cultured by traditional bacteriological methods and bacteria quantified by plate scores. Additionally, tracheal or bronchial swabs and apical lobe fluid were tested for Mycoplasma hyopneumoniae DNA and the superior tracheobronchial lymph nodes were tested for porcine circovirus type 2 DNA by polymerase chain reaction (PCR). All apparently significant bacteria were identified via PCR or sequencing. Typing was undertaken on some of the bacterial isolates. RESULTS: The most prevalent pathogens were M. hyopneumoniae, Streptococcus suis and Porcine Circovirus type 2, being found in 34, 38 and 31 batches, respectively. Other bacteria found were Actinobacillus species (29 batches), Pasteurella multocida (24 batches), Mycoplasma flocculare (9 batches), Actinobacillus pleuropneumoniae (7 batches), Mycoplasma hyorhinis (4 batches), Bisgaard Taxon 10 (1 batch), Glaesserella parasuis (1 batch), Streptococcus minor (1 batch) and Streptococcus porcinus (1 batch). Most batches had more than one bacterial species. CONCLUSION: The high percentage of batches infected with S. suis (83%), M. hyopneumoniae (74%) and PCV2 (70%) and clustering by a batch of these pathogens, as well as the presence of many secondary pathogens, suggests synergy between these organisms may have resulted in pleurisy.

BACKGROUND: Pleural and pericardial involvements are well recognized in eosinophilic granulomatosis with polyangiitis (EGPA) but considered rare manifestations of the other forms of antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). RESEARCH QUESTION: What are the frequency and clinical characteristics of pleuritis and pericarditis in AAV? STUDY DESIGN: and Methods: Using an institutional database of 1,830 patients with AAV, we analyzed clinical notes and diagnosis codes for key words related to pleuritis and pericarditis. Chart review to confirm these findings was performed. RESULTS: Eighty-eight of 1,058 patients (8.3%) with granulomatosis with polyangiitis (GPA), 27 of 267 (10.1%) with microscopic polyangiitis (MPA), and 35 of 201 (17.4%) with EGPA had a manifestation of pleuritis and/or pericarditis attributable to vasculitis. There was a higher frequency of pericarditis in EGPA compared with that in the other AAVs (P < .01). There was no difference in the frequency of pleuritis in GPA, MPA, or EGPA. In the 156 patients with AAV with pleuritis and/or pericarditis, this was a presenting feature in 127 (81.4%). Overall, it was a presenting feature in 6.9% of all patients with AAV, including 6.5% with GPA, 8.6% with MPA, and 15.9% with EGPA. INTERPRETATION: Pleuritis and pericarditis occur across all the AAVs and, when present, are commonly presenting features of these diseases. Patients with EGPA have a higher proportion of pericardial involvement compared with pleural involvement, whereas this distribution is more equal in patients with GPA and MPA. Pleuritis and pericarditis are underrecognized features of AAV. All forms of AAV should be considered in the differential diagnosis when evaluating a patient with pleuritis or pericarditis.

OBJECTIVES: Malignant rheumatoid arthritis (MRA) is defined as rheumatoid arthritis (RA) with systemic vasculitis or other severe extra-articular manifestations. Japan has a nationwide database for MRA. We analyzed the characteristics of Japanese patients with MRA based on data from the Ministry of Health, Labour and Welfare (MHLW). METHODS: We were permitted to use data on 43,108 patients who were registered in the MHLW database from 2003 to 2013. RESULTS: Median age was 65 (interquartile range, 57-72) years. Patients consisted of 71% females. Proportions of patients who had or had experienced interstitial pneumonia and pleuritis were increased, episcleritis was stable, and other MRA manifestations were decreased over time. The number of positive symptoms per patient also decreased over time. The median dose of glucocorticoid, percentage of patients undergoing surgery, and use of non-steroidal anti-inflammatory drugs and apheresis decreased year by year. Steinbrocker stage and class improved over time. Median C-reactive protein levels and erythrocyte sedimentation rate also decreased. Regarding social productivity levels of patients with MRA, the proportion of patients who were working or working from home increased and the proportion of patients recuperating or hospitalized decreased. CONCLUSION: In patients with MRA, disease activity decreased and social productivity improved from 2003 to 2013.

Respiratory disease is one of the major causes of losses to the pig industry worldwide. The pig subsector is the largest component of the livestock sector in the Philippines. Using lung scoring, this study aimed to estimate the prevalence of thoracic lesions in slaughter-age pigs in two provinces in the Philippines (Batangas and Albay) and define classes for respiratory health of pigs characterised by different patterns of thoracic lesions. A total of 260 pigs from Batangas and 300 pigs from Albay from either commercial or backyard farm types were included in this cross-sectional study. Lungs were scored for cranio-ventral pneumonia (0-55) and pleurisy (0-3). Presence or absence of pericarditis as well as focal dorso-caudal pneumonia were recorded. Latent class analyses considering four indicator variables, and province and farm type as covariates were used to explore different patterns of thoracic lesions across the study populations. Using a threshold of ≥7, the prevalence of a high lung score was 51.9% (95% confidence interval [CI]: 42.3-61.4%) and 13.7% (95% CI: 8.1-22.2%) in Batangas and Albay, respectively. Similarly, the prevalence of a pleurisy score of ≥1 was 56.9% (95% CI: 37.5-74.4%) and 5.0% (95% CI: 2.9-8.4%), pericarditis 24.6% (95%CI: 10.1-48.6%) and 1.7% (95%CI: 0.3-6.7%) and focal dorso-caudal pneumonia lesions 7.7% (95% CI: 3.7-15.5%) and 0% (97.5% one-sided CI: 0-1.2%), respectively. Latent class analyses identified four classes based on lung score, pleurisy score and the presence/absence of pericarditis: "healthy", "mild respiratory disease", "moderate pneumonia", and "multi-lesion". The relative frequency of these classes differed with province and farm type. Most pigs from Albay were "healthy", whereas in Batangas most pigs from commercial farms were "multi-lesion" and those from backyard farms were in the "mild respiratory disease" class. This study has provided baseline data on thoracic lesions in slaughter-age pigs for the provinces of Batangas and Albay in the Philippines. Targeting farms and areas where "multi-lesion pigs" are most common and further research to identify risk factors for particular classes should maximize impact of future control measures. The latent class analysis approach used could be applied more widely and could add value to analysis of multi-morbidity data collected routinely as part of ongoing monitoring schemes.

BACKGROUND: Etiological diagnosis of tuberculous pleuritis is challenging, owing to a paucity of Mycobacterium tuberculosis (MTB) in the affected region. Moreover, currently available methods, such as the detection of acid-fast bacilli and microbiological culture, are not always conducive to timely diagnosis and treatment. In this study, we evaluated the performance of Xpert® MTB/RIF assay (hereinafter referred to as "Xpert") in detecting MTB in difficult-to-diagnose patients using suspensions of pleural biopsy tissue specimens obtained under direct thoracoscopic guidance. METHODS: One hundred and sixty patients with an unexplained pleural effusion were included from the Shenyang Tenth People's Hospital and Shenyang Chest Hospital, China, between 2017 and 2018. The included patients underwent thoracoscopy under local anesthesia, with an intercostal incision of approximately 1.0 cm for biopsy. The biopsy specimens were used for pathological and etiological examinations. The Xpert test was evaluated for its sensitivity and specificity, as well as positive and negative predictive values (PPV and NPV, respectively), against data obtained using standards: the BACTEC™ MGIT™ 960 liquid culture system and a composite reference standard (CRS). RESULTS: The sensitivity and specificity of Xpert were 68.8 and 64.6%, respectively, against the MGIT 960 culture data. The PPV and NPV of Xpert were 56.4 and 75.6%, respectively. The sensitivity of Xpert was 69.0% against the CRS data, which was significantly higher than that of MGIT 960 culture (56.6%). The PPV and NPV of Xpert against the CRS data were 100.0 and 57.3%, respectively. CONCLUSIONS: Xpert is a good rule-in test but has limited value as a rule-out test for the diagnosis of tuberculosis pleuritis.

PURPOSE: Pleural infections are associated with significant inflammation, long hospitalizations, frequent comorbidities, and are often treated operatively-all of which are consequential risk factors for thrombo-embolic complications. However, their occurrence following the treatment of pleural infection is still unknown. The aim of the study was to ascertain the early and long-term occurrence of thrombo-embolic events in patients treated for pleural infections. METHODS: The study included all patients that were treated for pleural infections in Tampere University Hospital between January 2000 and December 2016. Data regarding later treatment episodes due to pulmonary embolisms and/or deep vein thromboses as well as survival data were requested from national registries. The rates were also compared to a demographically matched reference population adjusted for age, sex, and the location of residence. RESULTS: The final study population comprised 536 patients and 5318 controls (median age 60, 78% men). The most common etiology for pleural infection was pneumonia (73%) and 85% underwent surgical treatment for pleural infection. The occurrence of thrombo-embolic complications in patients and controls was 3.8% vs 0.1% at three months, 5.0% vs 0.4% at one year, 8.8% vs 1.0% at three years, and 12.4% vs 1.8% at five years, respectively, p < 0.001 each. Female sex, advanced age, chronic lung disease, immunosuppression, video-assisted surgery, and non-pneumonic etiology were associated with a higher incidence of thrombo-embolism. CONCLUSIONS: The occurrence of thrombo-embolic events-particularly pulmonary embolism but also deep vein thrombosis-was significant in patients treated for pleural infections, both initially and during long-term follow-up.

BACKGROUND: The Japan Society for Respiratory Endoscopy performed a nationwide survey to evaluate the current status and complications of bronchoscopy. Data on deaths due to bronchoscopy, complications after bronchoscopy, and particularly, complications of forceps biopsy were surveyed. METHODS: The survey form was mailed to 532 facilities accredited by the society. The numbers of procedures, complications, and deaths were investigated. RESULTS: The response rate was 79.1% (421 facilities). Deaths attributable to diagnostic bronchoscopy occurred in 11 (0.011%) of 98,497 cases.In regards to forceps biopsy, the guide sheath method was applied in 23,916 cases and the conventional method in 31,419 cases was done with conventional method. Complications of forceps biopsy developed in 1019 cases in total, with an incidence rate of 1.84%. The most frequent complication was pneumothorax (0.70%), followed by pneumonia/pleurisy (0.46%) and hemorrhage (0.45%). The incidence of hemorrhagic complication was significantly lower in the guide sheath group than in the non-guide sheath group (0.29% vs. 0.58%; P<0.001). The overall incidence of complications (1.63% vs. 2.00%; P=0.002) and the mortality rate (0% vs. 0.02%; P=0.04) were significantly lower in the guide sheath group. CONCLUSION: The incidence of hemorrhagic complications in forceps biopsy of peripheral pulmonary lesions was lower when the guide sheath method was applied. It is necessary to increase the awareness for safety control in diagnostic bronchoscopy for new procedures.

Systemic lupus erythematosus (SLE) severity, reflecting both disease intensity and duration, is heterogeneous making it challenging to study in administrative databases where severity may confound or mediate associations with outcomes. Garris et al. developed an administrative claims-based algorithm employing claims over a 1-year period to classify SLE severity as mild, moderate or severe. We sought to compare this administrative algorithm to a measure of SLE activity, the SLE Disease Activity Index-2000 (SLEDAI-2K) score at clinical visits. We identified 100 SLE patients followed in the Brigham and Women's Hospital (BWH) Lupus Center (in 2008-2010) with SLEDAI-2K scores at each visit over a 1-year period per person. We obtained data for the Garris algorithm for the same year per subject. We compared Garris SLE severity to the highest SLEDAI-2K in that year, with SLEDAI-2K categories of mild < 3, moderate 3-6, and severe > 6. We compared classification using weighted kappa statistics, and positive and negative predictive values (PPV, NPV). We also assessed the binary comparison of mild vs. moderate/severe. We calculated sensitivity, specificity, and McNemar's test. We analyzed 377 SLEDAI-2K assessments (mean 3.8 [SD 2.6] per subject/year). For classifying moderate/severe vs. mild SLE severity, the sensitivity was 85.7%, specificity 67.6%, PPV 81.8% and NPV 73.5%. The Garris algorithm for classifying SLE severity in administrative datasets had moderate agreement for classification of mild vs. moderate/severe SLE activity assessed by SLEDAI-2K assessments in an academic lupus center. It may be a useful tool for classifying SLE severity in administrative database studies.

Objectives: Most patients with familial Mediterranean fever (FMF) have their first attack at age < 20 years. Information about late-onset (age ≥40 years) FMF is limited. We aimed to evaluate the demographic, clinical, and genetic characteristics of late-onset FMF patients in the Japanese population.Methods: We retrospectively analyzed 292 patients with FMF. Patients were divided into three groups according to age of disease onset: Group I, ≤19 years; Group II, 20-39 years; and Group III, ≥40 years.Results: Of 292 patients, 44 (15.1%) experienced their first attack at age ≥40 years. While high fever (97.7%) and arthritis (45.5%) were common symptoms in Group III patients, peritonitis (40.9%) and pleuritis (25.0%) were significantly lower than in other groups. The frequency of patients carrying p.M694I (18.2%), which is the most representative mutation in Japan, was significantly lower in Group III than in Group I. The response to colchicine therapy was good (95.1%) and similar in all groups.Conclusions: In Japan, more patients than expected had late-onset FMF. They had a milder form of disease, with less frequent peritonitis and pleuritis. The response to colchicine treatment was good. Clinicians should consider FMF for patients with unexplained recurrent febrile episodes, regardless of age.

OBJECTIVE: Systemic lupus erythematosus (SLE) predominantly affects women, but previous studies suggest that men with SLE present a more severe disease phenotype. In this study, we investigated a large and well-characterized patient group with the aim of identifying sex differences in disease manifestations, with a special focus on renal involvement. METHODS: We studied a Swedish multi-center SLE cohort including 1226 patients (1060 women and 166 men) with a mean follow-up time of 15.8 ± 13.4 years. Demographic data, disease manifestations including ACR criteria, serology and renal histopathology were investigated. Renal outcome and mortality were analyzed in subcohorts. RESULTS: Female SLE patients presented more often with malar rash (p < 0.0001), photosensitivity (p < 0.0001), oral ulcers (p = 0.01), and arthritis (p = 0.007). Male patients on the other hand presented more often with serositis (p = 0.0003), renal disorder (p < 0.0001), and immunologic disorder (p = 0.04) by the ACR definitions. With regard to renal involvement, women were diagnosed with nephritis at an earlier age (p = 0.006), while men with SLE had an overall higher risk for progression into end-stage renal disease (ESRD) with a hazard ratio (HR) of 5.1 (95% CI, 2.1-12.5). The mortality rate among men with SLE and nephritis compared with women was HR 1.7 (95% CI, 0.8-3.8). CONCLUSION: SLE shows significant sex-specific features, whereby men are affected by a more severe disease with regard to both renal and extra-renal manifestations. Additionally, men are at a higher risk of developing ESRD which may require an increased awareness and monitoring in clinical practice.

The aim of this study was to identify the prevalence of pathological lesions in pigs from small-scale farms and to determine associations between pathological lesions and hematological parameters, and carcass and meat quality in slaughtered pigs. The study was conducted on 625 pigs (~115 kg) originating from 20 small-scale farms. Any signs of pneumonia, pleurisy, pericarditis, and liver milk spots were recorded as present or absent. Complete blood count was investigated. The following carcass quality parameters were measured: live, hot and cold carcass weights, cooling loss, dressing percentage, backfat thickness, and meatiness. Meat pH and temperature were measured 45 min postmortem. Of the 625 examined pigs, 41.8% had pneumonia, 23.5% pleurisy, 2.7% pericarditis, and 29.9% liver milk spots. The presence of pathological lesions in slaughtered pigs adversely affected hematological parameters, reduced live, hot and cold carcass weights, and meatiness and had deleterious effects on meat quality (higher pH45min and higher prevalence of dark, firm and dry meat). In conclusion, this study showed a high prevalence of pathological lesions in slaughtered pigs, indicating serious health problems in smallholder pig production systems. The presence of single and, especially, multiple pathological lesions in slaughtered pigs negatively affected hematological parameters, and carcass and meat quality.

A study was conducted on 21 pig herds using one-site production system in the southeast region of Brazil to assess the relationships among serological results for primary pathogens involved in respiratory diseases (Actinobacillus pleuropneumoniae, App; Mycoplasma hyopneumoniae, Mhyo; and swine influenza virus, SIV), cough index, pneumonia index, pleuritis and herd characteristics. The prevalence of antibodies against Mhyo and SIV increased throughout the raising phases, with the highest prevalence in slaughtered pigs (> 40%), while pigs in 65% (14/21) of nurseries demonstrated marked seroprevalence of App that decreased until the day of slaughter. Pleuritis and pulmonary consolidations were recorded in 9.0 and 72.4%, respectively, of the 908 evaluated lungs. Histopathological analysis of the lung lesions revealed suppurative bronchopneumonia in almost half of the lungs (48.9%). Regression analyses were conducted to identify risk factors associated with the cough index; pleuritis; pulmonary consolidation; and App, Mhyo and SIV serological results. All-in-all-out management in nursery buildings reduced the seroprevalence of Mhyo in herds. App seroprevalence was associated with pleuritis, and the presence of cough episodes in growing pigs was associated with SIV seropositivity in nursery pigs.

Non-specific pleuritis (NSP) is defined as fibrinous or inflammatory pleuritis which cannot be attributed to a specific benign or malignant etiology. It can be diagnosed in biopsies in up to 30% of cases of exudative pleuritis after thoracoscopy, with a mean of 19.2%. In 66 out of 469 (14.2%) patients in combined series, a malignant pleural disease (mostly mesothelioma) was found during a follow-up of at least 21 months. Most likely, a follow-up time of 12 months is sufficient, although the current routine is a follow-up of 2 years. Because of a benign course in 85% of patients with NSP, a repeated invasive procedure after thoracoscopy is only indicated in a limited group of patients. The most important indications for a repeated pleural biopsy are persistent chest pain, recurrent pleural effusion, radiologic findings suggestive for malignant pleural disease.

BACKGROUND AND OBJECTIVE: Malignant pleurisy is associated with advanced oncological disease and dyspnoea is the most common presenting symptom. Pleurodesis is the preferred palliative and supportive treatment option, targeting symptom relief. The identification of clinical and endoscopic features that determine the success of talc pleurodesis in malignant pleurisy could guide clinical decision-making. METHODS: All symptomatic patients with malignant pleurisy subjected to talc pleurodesis through medical thoracoscopy between January 2012 and December 2015 were included. Univariate and multivariate analyses were performed to identify factors associated with successful pleurodesis. RESULTS: Of the 155 patients, 122 (78%) were classified as having a successful pleurodesis based on clinical and radiological criteria. Factors associated with unsuccessful pleurodesis (univariate analysis) were the presence of pleural adhesions (odds ratio (OR): 0.43 (95% CI: 0.19-0.96); P = 0.04), extensive spread of pleural lesions (OR: 0.17 (95% CI: 0.05-0.59); P = 0.001), the use of systemic corticosteroids (OR: 0.28 (95% CI: 0.10-0.83); P = 0.02) and a prolonged time period between the clinical diagnosis of the pleural effusion and the moment of pleurodesis (OR: 0.14 (95% CI: 0.06-0.32); P < 0.0001). The latter being associated with failure of pleurodesis in a multivariate analysis (OR: 0.08 (95% CI: 0.01-0.25); P < 0.0001). Chest ultrasound prior to pleurodesis showed a sensitivity of 91% and a specificity of 88% in predicting the success of pleurodesis. CONCLUSION: The success rate of pleurodesis in malignant pleurisy could potentially be enhanced by correct patient selection and early referral for pleurodesis. Ultrasonic assessment of pleural adhesions and potential lung expansion prior to pleurodesis is useful in clinical decision-making.

OBJECTIVE: The aims of this study were to evaluate whether treatment with tumor necrosis factor (TNF) inhibitors in patients with rheumatoid arthritis (RA) affects the risk of developing severe extraarticular rheumatoid arthritis (ExRA) manifestations and to investigate potential predictors for developing ExRA. METHODS: A dynamic community-based cohort of patients with RA was studied (n = 1977). Clinical records were reviewed and cases of severe ExRA were identified. Information on exposure to TNF inhibitors was obtained from a regional register. Exposure to TNF inhibitors was analyzed in a time-dependent fashion and the incidence of severe ExRA in exposed patients was compared with the incidence in unexposed patients. Cox regression models were used to assess potential predictors of severe ExRA. RESULTS: During treatment with TNF inhibitors, there were 17 patients with new onset of severe ExRA in 2400 person-years at risk (PY; 0.71/100 PY, 95% CI 0.41-1.13) compared with 104 in 15,599 PY (0.67/100 PY, 95% CI 0.54-0.81) in patients without TNF inhibitors. This corresponded to an incidence rate ratio of 1.06 (95% CI 0.60-1.78). The age- and sex-adjusted HR for ExRA in anti-TNF-treated patients was 1.21 (95% CI 1.02-1.43), with similar findings in models adjusted for time-dependent Health Assessment Questionnaire and propensity for anti-TNF treatment. Male sex, positive rheumatoid factor (RF), long disease duration, and greater disability were predictors for ExRA. CONCLUSION: This study suggests that patients treated with TNF inhibitors are at a slightly increased risk of developing severe ExRA. RF-positive patients with disabling disease of long duration were more likely to develop severe ExRA.

OBJECTIVE: The aim of this study was to develop a perioperative metastatic spinal tumor frailty index (MSTFI) that could predict morbidity, mortality, and length of stay. METHODS: A large inpatient hospitalization database was searched from 2002 to 2011 to identify 4583 patients with spinal metastasis from breast (21.1%), lung (34.1%), thyroid (3.8%), renal (19.9%), and prostate (21.1%) cancer who underwent surgery. A multiple logistic regression model identified 9 independent parameters that were used to construct the MSTFI: anemia, chronic lung disease, coagulopathy, electrolyte abnormalities, pulmonary circulation disorders, renal failure, malnutrition, emergent/urgent admission, and anterior/combined surgical approach. Patients with 0 points were categorized as "not frail," 1 as "mildly frail," 2 as "moderately frail," and ≥3 as "severely frail." RESULTS: The overall perioperative complication rate was 19.3% and in-patient mortality was 3.0%. Compared with patients with no frailty, patients with moderate frailty (odds ratio [OR] 5.15; 95% confidence interval [95% CI] 2.44-10.86), and severe frailty (OR 5.74; 95% CI 2.69-12.24) had significantly increased odds of inpatient mortality (all P < 0.001). Similarly, patients with mild frailty (OR 1.88; 95% CI 1.33-2.66), moderate frailty (OR 3.83; 95% CI 2.71-5.41), and severe frailty (OR 6.97; 95% CI 4.98-9.74) had significantly increased odds of developing a major in-hospital complication (all P < 0.001). Length of stay also increased significantly by MSTFI (P < 0.001). CONCLUSIONS: In surgically treated patients with spinal metastasis, certain perioperative parameters may significantly predict the risk of major in-hospital complications and mortality.

PURPOSE OF REVIEW: This article summarizes current data regarding the accuracy of pleural fluid tests assisting the diagnosis of tuberculous pleuritis (TBP). RECENT FINDINGS: No pleural fluid test reliably rules-in TBP in settings with low TBP prevalence. Interferon-γ) alone or in combination with adenosine deaminase (ADA) is more reliable than ADA for this purpose in nonlow prevalences. ADA can reliably rule-out TBP in prevalences of less than 40% although in higher prevalences the product of interleukin-27 and ADA is the most accurate rule-out test. SUMMARY: The definite diagnosis of TBP requires the isolation of Mycobacterium tuberculosis from pleural fluid or biopsies. Because of the low sensitivity of pleural fluid cultures and the invasiveness of pleural biopsy techniques, the concept of a pleural fluid test that accurately establishes or excludes TBP diagnosis has been proposed. Numerous pleural fluid tests have been evaluated for this purpose with ADA being the most widely accepted one. During the last years, it has been demonstrated that the ability of ADA to rule-in or rule-out TBP is affected by the prevalence of TBP in the setting where the test is used. The complementary use of interferon-γ or interleukin-27 increases the ability of ADA to rule-in or rule-out the disease, respectively.
