Abstract
This review is based investigations on the Western Isles, Scotland, by Martin Martin, a notable Scottish Highlander, academic and medical doctor, of the 17th-18th century. His extensive observations of the geography and peoples of these Isles were recorded in his books, "On the Description of the Western Islands of Scotland Circa 1695" and "A Late Voyage to St Kilda". In these books and subsequent papers there were some noteworthy observations on the occurrence (and as he says non-occurrence) of "epidemical" diseases and conditions afflicting the peoples of The Isle of Skye and the Western Isles of Scotland in this period, and these are discussed in this review. Martin also gives details of a wide variety of remedies that were observed or reported by inhabitants around that time. Some of these remedies are interesting for their relevance to the period but others are of doubtful merit. These are reviewed here more for their significance in the understanding of the diseases and conditions of humans and even in some cases animals at that time. Introductions by Charles Withers and R.W. Munro, 11 and re-assessments of the contributions of Martin and colleagues of that time have given insight into the health and condition of peoples of the Western Isles of Scotland(the Occidental) (Martin 1695; Martin 1716).

Abstract
The aim of this work was to compare the anti-inflammatory and antioxidant effects of three natural coumarins: 1,2-benzopyrone, umbelliferone and esculetin. The antioxidant capacity of coumarins was evaluated using both chemical and biological in vitro assays. Chemical assays included DPPH and ABTS∙+ radical scavenging as well as ferric ion reducing ability power (FRAP) assay. Inhibition of mitochondrial ROS generation and lipid peroxidation in brain homogenates were used as biological in vitro assays. The experimental method of carrageenan-induced pleurisy in rats was used for the in vivo investigation of the anti-inflammatory activity. In silico molecular docking analysis was undertaken to predict the affinity of COX-2 to the coumarins. Considering the antioxidant capacity, esculetin was the most efficient one as revealed by all employed assays. Particularly, the mitochondrial ROS generation was totally abolished by the compound at low concentrations (IC50 = 0.57 μM). As for the anti-inflammatory effects, the COX-2 enzyme presented good affinities to the three coumarins, as revealed by the molecular docking analyses. However, considering the in vivo anti-inflammatory effects, 1,2-benzopyrone was the most efficient one in counteracting pleural inflammation and it potentiated the anti-inflammatory actions of dexamethasone. Umbelliferone and esculetin treatments failed to reduce the volume of pleural exudate. Overall, therefore, our results support the notion that this class of plant secondary metabolites displays promising effects in the prevention and/or treatment of inflammation and other diseases associated with oxidative stress, although the singularities regarding the type of the inflammatory process and pharmacokinetics must be taken into account.

Abstract
BACKGROUND Across the European Union (EU), efforts are being made to achieve modernisation and harmonisation of meat inspection (MI) code systems. Lung lesions were prioritised as important animal based measures at slaughter, but existing standardized protocols are difficult to implement for routine MI. This study aimed to compare the informative value and feasibility of simplified lung lesion scoring systems to inform future codes for routine post mortem MI. RESULTS Data on lung lesions in finisher pigs were collected at slaughter targeting 83 Irish pig farms, with 201 batches assessed, comprising 31,655 pairs of lungs. Lungs were scored for cranioventral pulmonary consolidations (CVPC) and pleurisy lesions using detailed scoring systems, which were considered the gold standard. Using the data collected, scenarios for possible simplified scoring systems to record CVPC (n = 4) and pleurisy (n = 4) lesions were defined. The measurable outcomes were the prevalence and (if possible) severity scoring at batch level for CVPC and pleurisy. An arbitrary threshold was set to the upper quartile (i.e., the top 25% of batches with high prevalence/severity of CVPC or pleurisy, n = 50). Each pair of measurable outcomes was compared by calculating Spearman rank correlations and assessing if batches above the threshold for one measurable outcome were also above it for their pairwise comparison. All scenarios showed perfect agreement (k = 1) when compared among themselves and the gold standard for the prevalence of CVPC. The agreement among severity outcomes and the gold standard showed moderate to perfect agreement (k = [0.66, 1]). The changes in ranking were negligible for all measurable outcomes of pleurisy for scenarios 1, 2 and 3 when compared with the gold standard (rs ≥ 0.98), but these changes amounted to 50% for scenario 4. CONCLUSIONS The best simplified CVPC scoring system is to simply count the number of lung lobes affected excluding the intermediate lobe, which provides the best trade-off between value of information and feasibility, by incorporating information on CVPC prevalence and severity. While for pleurisy evaluation, scenario 3 is recommended. This simplified scoring system provides information on the prevalence of cranial and moderate and severe dorsocaudal pleurisy. Further validation of the scoring systems at slaughter and by private veterinarians and farmers is needed.

Abstract
Anthracosis of lung is assumed to be a disease that causes parenchymal accumulation of macrophage-laden anthracotic nodules, which leads to bronchial obstruction, lung mass, and lymphadenopathy. Pleural surface anthracosis involvement as extra-parenchymal involvement has been rarely reported. Still, due to presentation with a transudate pattern, pleural effusion is considered to be a side effect of lung collapse. I represent two subjects with patches of anthracosis in the presumptive place of anatomical fenestra of lymphatic vessels in the parietal pleural. It may cause inhibition of reabsorption of pleural fluid and finally accumulation of transudate pleural effusion. Involvement of the pleura by anthracosis, and black discoloration of the parietal pleura have already been discovered by physicians who perform pleuroscopy. The pleural involvement by anthracosis is usually diffuse. In these two subjects, pleural involvement was in the early stage of anthracosis, which helped me to introduce a new mechanism for transudative pleural effusion due to blockage of the pleural lymphatic channels entrance.

Abstract
BACKGROUND Pleurisy is an inflammation of the parietal pleura and is characterized by pleuritic pain. The most common cause of pleurisy is infection; other causes include rheumatoidarthritis, malignancy, rib fractures, or trauma. Possible causes of chest pain associated withgolf include costochondritis, stress fractures of the ribs, intercostal muscle strain, or, rarely,Tietze's syndrome and slipping rib syndrome. CASE A 64-year-old female presented with intractable chest pain that began 4 months priorwhile playing golf. No specific cause was found after various examinations. There was persistent pain despite medical treatment. Ultrasonography (US) was performed over the painful areas, which revealed focal pleural effusions. A mixture of ropivacaine and triamcinolonewas injected into the focal pleural effusions using US guidance, which dramatically relievedher pain. CONCLUSIONS This case demonstrates that US can be used as a diagnostic and therapeuticmodality for intractable chest pain with an undetected pathology.

Abstract
Background and aim Kaempferia galanga, also known as aromatic Ginger (kencur) in Indonesia, has been widely explored and shows potential as an anti-inflammatory agent. However, there has been limited research to show a possible mechanism by which aromatic ginger inhibits lipoxygenase (LOX). Therefore, this study aims to determine the anti-inflammatory activity of aromatic ginger by comparing extract, fractions, and ethyl-p-methoxycinnamate (EPMC) isolate, as well as possible LOX inhibition activity, by reducing the production of leukotriene B4 (LTB4). Experimental procedure Two animal models were used, namely, the carrageenan-induced granuloma air pouch model and the pleurisy model. The test substance was administered 1 h before carrageenan induction, which was performed orally for each animal model. The number of leukocytes and the malondialdehyde (MDA) levels, leukotriene B4 (LTB4) levels, and histology were observed. GC-MS and LC-MS were used for analysis of the chemical compounds in the test samples. Results and conclusion The results of GC-MS analysis showed that aromatic ginger rhizome extract and fractions were dominated by ethyl-trans-p-methoxycinnamate, with the highest level found in the extract. K. galanga showed significant anti-inflammatory activity compared to the control (p < 0.01) in both the granuloma air pouch and pleurisy models. The results of examining the LTB4 concentration showed comparable activity between K. galanga extract, fractions and EMPC isolate, these results were not better than those of zileuton. Overall, this study shows that aromatic ginger extract, fractions and EPMC isolate have anti-inflammatory properties and have the potential to inhibit LOX, thereby reducing LTB4 levels. Comparison of extract, fraction and isolate of Kamperia galanga anti-inflammation activity. Anti-inflammatory activity of Kaempferia galanga in pleurisy model. Extract, fraction and isolate of Kamperia galanga as LOX inhibitor.

Abstract
Nitric oxide (NO) regulates various physiological and pathophysiological functions in the lungs. However, there is much less information about the effects of NO in the pleura. The present review aimed to explore the available evidence regarding the role of NO in pleural disease. NO, has a double-edged role in the pleural cavity. It is an essential signaling molecule mediating various physiological cell functions such as lymphatic drainage of the serous cavities, the immune response to intracellular multiplication of pathogens, and downregulation of neutrophil migration, but also induces genocytotoxic and mutagenic effects when present in excess. NO is implicated in the pathogenesis of asbestos-related or exudative pleural disease and mesothelioma. From a clinical point of view, the fraction of exhaled NO has been suggested as a potential non-invasive tool for the diagnosis of benign asbestos-related disorders. Under experimental conditions, NO-mimetics were found to attenuate hypoxia-induced therapy resistance in mesothelioma. Similarly, hybrid agents consisting of an NO donor coupled with a parent anti-inflammatory drug showed an enhancement of the anti-inflammatory activity of anti-inflammatory drugs. However, given the paucity of research work performed over the last years in this area, further research should be undertaken to establish reliable conclusions with respect to the feasibility of determining or targeting the NO signaling pathway for pleural disease diagnosis and therapeutic management.

Abstract
Background Intrapleural urokinase is one of the most widely used fibrinolytic agents in the treatment of complicated parapneumonic effusion (CPPE). However, little research has been performed on the optimal urokinase dosage. The aim of this study was to evaluate the treatment efficacy of half dose urokinase compared with conventional dose urokinase. Methods We retrospectively enrolled 92 patients with CPPE or empyema who underwent intrapleural urokinase treatment at two tertiary hospitals. Patients received antibiotics, chest tube drainage, and other treatments as part of routine care. The primary outcome was the treatment success rate in the half dose urokinase group (50,000 IU daily for maximal 6 days) and the conventional dose urokinase group (100,000 IU daily). Treatment success was defined as clinical and radiological improvements without surgical treatment or re-admission within one month. Results Forty-four patients received half dose urokinase, whereas 48 patients were treated with conventional dose urokinase. Both groups were relatively well matched at baseline, excluding higher serum white blood cell count and higher empyema prevalence in the half dose urokinase group. The treatment success rate was not different between the two groups (p=0.048). There were no differences in the rate of in-hospital death and surgical treatment, hospitalization duration, and indwelling catheter duration. In the multivariate analysis, urokinase dose was not a predictor of treatment success. Conclusion Half dose intrapleural urokinase is equally effective conventional dose urokinase in treating patients with CPPE or empyema.

Abstract
Background Pluck lesions are associated with decreased performance in grower-finisher pigs, but their economic impact needs to be further investigated. This study aimed to identify the main pluck lesions and the cut-off value for their prevalence, associated with changes in average daily gain (ADG) during the wean-to-finish period, to simulate their effects on economic performance of farrow-to-finish farms. Pigs (n = 162 ± 51.9 per farm) from 56 farrow-to-finish farms were inspected at slaughter and the prevalence of enzootic pneumonia-like lesions, pleurisy, lung scars, abscesses, pericarditis, and liver milk spots was estimated. For each farm, annual performance indicators were obtained. Regression trees analysis (RTA) was used to identify pluck lesions and to estimate cut-off values for their prevalence associated with changes in ADG. Different scenarios were simulated as per RTA results and economic and risk analyses were performed using the Teagasc Pig Production Model. Risk analysis was performed by Monte Carlo sampling using the Microsoft Excel add-in @Risk with 10,000 iterations. Results Pleurisy and lung scars were the main lesions associated with changes in ADG. Three scenarios were simulated based on RTA results: a 728 sow farrow-to-finish farm with prevalence of i) pleurisy < 25% and lung scars < 8% (LPLSC; ADG = 760 g); ii) pleurisy < 25% and lung scar ≥8% (LPHSC; ADG = 725 g) and iii) pleurisy ≥25% (HP; ADG = 671 g). The economic analysis showed increased feed and dead animals for disposal costs, and lower sales in the HP and LPHSC scenarios than in the LPLSC scenario; thereby reducing gross margin and net profit. Results from the risk analysis showed lower probability of reaching any given level of profit in the HP scenario compared with the LPHSC and LPLSC scenarios. Conclusion Under the conditions of this study, higher prevalence of pleurisy and lung scars were associated with decreased ADG during the grower-finisher period and with lower economic return in the simulated farms. These results highlight the economic benefits and importance of preventing and/or controlling respiratory disease.

Abstract
Background Serological screening is a common method to monitor antibody response to pathogen exposure, but results could vary due to several factors. This study aimed to quantify animal and management related factors associated with variation in antibody levels in finisher pigs at slaughter, in an Irish farrow-to-finish farm endemically infected with Actinobacillus pleuropneumonia (App), Mycoplasma hyopneumoniae (Mhyo) and swine influenza virus (SIV). A second objective was to estimate differences in antibody levels in pigs presenting pluck lesions. This was an observational study whereby pigs were managed as per routine farm practice. Data on sow parity, number of born alive (NBA) pigs per litter, cross-fostering status, birth and weaning body weight were recorded from 1016 pigs born from one farrowing batch. At slaughter, blood samples were collected for serological analysis and pigs were inspected for presence of enzootic pneumonia (EP)-like lesions, pleurisy, pericarditis and heart condemnations. Pigs were retrospectively classified into three production flows, depending on time spent in each production stage: flow 1 (F1; pigs followed the normal production flow); flow 2 (F2; pigs which were delayed by 1 week from advancing forward); and flow 3 (F3; pigs delayed by > 1 week from advancing forward). A nested case-control design was applied by matching pigs from each flow by sow parity, birth weight and NBA. Results Pigs born from primiparous sows had higher antibody levels for App than those born to parity ≥5 sows (P < 0.05) and there was no association between any of the pathogens investigated and other early life indicators (P > 0.05). Pigs in F1 had lower antibody levels for App but higher antibody levels for SIV than F2 and F3 pigs (P < 0.05). There was no association between pluck lesions and respiratory pathogens (P > 0.05), except for increased antibody levels for Mhyo when EP-like lesions were present (P = 0.006). Conclusion Results indicate that offspring from primiparous sows develop higher antibody levels for App IV toxin when exposed to this disease and that enforcement of a strict all-in/all-out production system would reduce on-farm disease circulation. A high percentage of pigs were affected with EP-like lesions which were associated with higher antibody levels for Mhyo.

Abstract
Background Chronic pleurisy is a common finding in slaughtered pigs in post-mortem meat inspection. The prevalence of pleurisy has been increasing during the last decade also in Finland. The aim of this prospective case-control study was to search for environmental, infectious and management-related herd-level risk factors for pleurisy in the slaughterhouse. Altogether 46 Finnish pig herds, including 25 control (low pleurisy prevalence in meat inspection) and 21 case (high pleurisy) herds, were enrolled in the study and visited during the tenth week of the rearing period of finishing pigs. Herd personnel were asked about basic herd information, management and environmental factors. Selected pigs were examined clinically, environmental parameters were measured and 15 blood samples per herd were taken during herd visits. Antibodies against Actinobacillus pleuropneumonia serotype 2 (APP2) and ApxIV toxin and swine influenza virus were measured. After the slaughter of study pigs, meat inspection results of the batch were gathered from slaughterhouses. Multivariate logistic regression model was built to identify possible risk factors for a herd to be a case herd (i.e. having high pleurisy values). Results Finishing herd type and herd size were observed to act as risk factors. None of clinical signs of pigs, management-related factors or environmental measurements were associated with herd status. Conclusions As previously known, in endemic and subclinical infections such as APP, herd factors are important, but detailed risk factors seem to be difficult to identify.

Abstract
Nitric oxide (NO) is an important part of the host defense mechanism; however, it displays both pro- and anti-inflammatory properties depending on its location and concentration. Importantly, excessive or inappropriate NO production can cause tissue damage. Systemic and local administration of NO synthase (NOS) inhibitors ameliorates and may exacerbate the inflammatory response, respectively. Here, we used a carrageenan-induced pleurisy model of acute inflammation in rats to confirm the location-dependent effects of NO and investigate the underlying mechanisms. As expected, localized suppression of NO production exacerbated inflammation, as evidenced by increased pleural exudate volumes and leukocyte counts and enhanced activity of enzymes related to oxidative stress. In contrast, local NO supplementation reduced leukocyte infiltration, vascular permeability, and the activity of oxidative stress-related enzymes. Interestingly, inhibition of heme oxygenase-1 (HO-1) reversed the anti-inflammatory effects of localized NO production, while the addition of hemin (HO-1 substrate) or carbon monoxide (CO; HO-1 metabolite) decreased leukocyte migration and exudation. Together, these findings confirm a protective role for NO at the inflammatory site, which appears to be mediated via NOS induction of the HO-1/CO pathway. Thus, NO supplementation may be a potential new treatment for oxidative stress-associated inflammatory diseases. Systemic NOS inhibition ameliorated inflammation in a rat Cg-induced pleurisy model. Conversely, localized NOS inhibition increased all examined markers of inflammation. HO-1, hemin, and CO enhanced the localized anti-inflammatory effects of NO. NOC-18, l-arginine, hemin, and CORM-3 decreased levels of inflammatory cytokines. The localized anti-inflammatory effect of NO may be mediated via the HO-1/CO pathway.

Abstract
Background The collected works of Hippocrates were searched for concepts on the diagnosis, prognosis, and treatment of acute and urgent respiratory diseases, with the objective to trace their origins in the Hippocratic Collection. Methods A scoping review was performed to map out key concepts of acute and severe respiratory diseases in the entire Hippocratic Collection. The digital library Thesaurus Lingua Graeca (TLG) was researched for references in the entire Hippocratic Collection regarding the epidemiology, pathophysiology, prognosis, diagnosis and treatment of acute respiratory diseases; then, the relevant texts were studied in their English translation by the Loeb Classical Library. Results Hippocratic physicians followed principles of treatment for pneumonia and pleurisy, still relevant, such as hydration, expectoration, analgesia and prompt mobilisation. Other approaches, including the inhalation of “vapours through tubes” in angina, can be considered as forerunners of modern medical practice. Thoracic empyema was diagnosed by shaking the patient and direct chest auscultation after “applying your ear to his sides”. In case of an emergency from upper airway obstruction, urgent insertion of primitive airway equipment, such as a small pharyngeal tube, was applied. Conclusions The main Hippocratic concepts on four still common acute and urgent respiratory diseases −pneumonia, pleurisy, thoracic empyema and upper airway obstruction− were identified and most of them were found to be in agreement with contemporary medical thinking and practice.

Abstract
A 78-year-old Japanese man, undergoing maintenance hemodialysis for 20 years and having received coronary artery bypass grafting two months before, was hospitalized because of fever with subclinical left-sided pleurisy. Achromobacter xylosoxidans strains exhibiting identical genomic patterns on a macrorestriction analysis were isolated from the blood and the pleural effusion obtained on admission. Physical and radiological examinations did not reveal any lesions in either chest wall or lung adjacent to the effusion, indicating that the organism in the effusion had entered the pleural space via the bloodstream. Immunocompromising conditions due to undergoing maintenance hemodialysis and the presence of the antecedently accumulated pleural effusion may have been associated with the development of hematogenous dissemination. The patient fully recovered only with antibiotic therapy. To our knowledge, the present report is the first describing a case of hematogenous pleural infection caused by A. xylosoxidans.

Abstract
The parietal pleura is often biopsied in patients with idiopathic pleural effusion, and in up to 40% of cases, a diagnosis of nonspecific pleuritis/fibrosis (NSP) is rendered. The histology of this reaction has not been well described including a pattern of B cell lymphoid hyperplasia described as "chronic follicular pleuritis (CFP)". Thirty-two cases of NSP were studied, of which 13 (41%) corresponded to CFP with the remainder displaying a fibrinous and organizing pleuritis with varying degrees of collagenization. CFP had similar etiologies as NSP with long term follow-up, including cardiac disease, pericarditis, asbestos exposure, and occult malignancy. The importance of recognizing a previously undescribed B cell/plasma cell pleural inflammatory response in reactive pleural disease is discussed.

Abstract
INTRODUCTION The incidence of pleural disease continues to increase worldwide. Medical thoracoscopy remains the standard method for exploration of the pleural cavity. METHOD We report the retrospective evaluation, the efficacy and the observed complications in 1024 medical thoracoscopies undertaken in the University Hospital of Liège between 2000 and 2017. RESULTS In total, 100 pneumothoraces and 400 benign and 501 malignant pleural diseases were identified. The main indication for thoracoscopy remains the diagnosis of an exudative, lymphocytic pleural effusion of unknown aetiology after thoracocentesis. The diagnostic sensibility of thoracoscopy was 99.2% in distinguishing benign from malignant pleural disease. Talc pleurodesis was performed in 69.5% of the total population and in 66.1% of pleural effusions or thickening. Failure of pleurodesis was observed in 11% of the patients with recurrent pneumothorax and in 7.8% of neoplastic pleural effusion. We report a mortality of 0.6% in the 30 days post procedure, long duration of drainage in 8.3% and serious complications in 4.7%. In 22/1024 (2.1%) thoracoscopic evaluation was not feasible because of dense pleural fibrosis. CONCLUSION Medical thoracoscopy is a safe, well-tolerated procedure with high accuracy in the diagnostic and therapeutic management of pleural disease.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mikania glomerata Spreng. (MG) and Mikania laevigata Sch. Bip. ex Baker (ML), popularly known as guaco, are medicinal plants similar in morphology, chemical composition and medicinal uses. Both species are often used and sold without distinction; however, it is believed that their chemical composition is different. AIM Thus, the aim of this study is to investigate if the aqueous extract of MG and ML present similar anti-inflammatory activity to the point of being used interchangeably. MATERIAL AND METHODS Different doses of both extracts and coumarin were given to rats in different experimental models to assess the anti-inflammatory activity between these two species. For this, the animals were submitted to paw edema, pleurisy and degranulation of peritoneal mast cell and the extracts were also characterized by Ultra High Efficiency Liquid Chromatography coupled to Mass Spectrometry (UHPLC-MS). RESULTS The chromatographic method showed that ML presents ten times more coumarin than MG. Oral administration of MG, ML and coumarin inhibited paw edema induced by carrageenan (400 mg/kg, 55% inhibition; 400 mg/kg, 57% inhibition; 75 mg/kg, 38% inhibition; p < 0.05, respectively). MG, ML and coumarin treatment also inhibited the edema induced by compound 48/80 (400 mg/kg, 56% inhibition; 400 mg/kg, 69% inhibition; 75 mg/kg, 40% inhibition; p < 0.05, respectively). MG, ML and coumarin did not prevent mast cell degranulation and the consequent histamine release in Wistar rat peritoneal mast cells induced by compound 48/80. MG did not inhibit cell infiltration in pleurisy nor the highest dose tested, while ML decreased the leukocyte migration (200 and 400 mg/kg, 23% and 30% inhibition; p < 0.001, respectively) and, to a lesser extent, coumarin also reduced cell infiltration (10, 50 and 75 mg/kg; 15%, 16% and 17% inhibition; p < 0.001, respectively). CONCLUSION The variation of the results of the anti-inflammatory activity found in M. glomerata and M. laevigata demonstrates that these two species should not be used interchangeably. Coumarin, as already proven, has anti-inflammatory action however, we have suggested that it probably is not the only component responsible for this therapeutic effect in the extracts.

Abstract
Urinothorax refers to the presence of urine in the pleural space. Urinothorax is an infrequent and underdiagnosed pathology, with few cases reported, and these often suspected only with hindsight. It is usually a transudative pleural effusion. We report a case of urinothorax presenting as a purulent pleural effusion. Management of the urinothorax required antibiotics and surgical unblocking of the urinary tract. Currently, no test is available to confirm the diagnosis. The ratio of serum creatinine/pleural creatinine could suggest the presence of urinothorax but this parameter needs to be validated by complementary studies. Urinothorax should be suspected in the context of pleural effusion occurring after a recent urologic surgery.

Abstract
Bean's syndrome ('blue rubber bleb nevus syndrome') is a rare disease characterized by venous malformations involving various organs. Most often these lesions are localized to the skin and the digestive system. Gastro-intestinal bleeding is the most frequent presentation. Though other organs can be affected, chest localizations are infrequent and pleural localization is exceptional. We report the case of an asbestos-exposed patient with Bean's syndrome with characteristic skin lesions, smoker, hospitalized for the investigation of a hemorrhagic pleural effusion. A medical thoracoscopy revealed pleural lesions similar to the cutaneous lesions and compatible with a pleural localization of the disease. This is the first documented case of this disease involving the pleura. A review of the literature was carried out on account of this clinical case.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Leaves from Psidium guineense Sw. are used in popular medicine for the treatment of inflammatory disease. However, there is no scientific evidence demonstrating this activity. AIM OF THE STUDY To evaluate the antioxidant, anti-inflammatory, antiproliferative and antimycobacterial activities of the essential oil of P. guineense and spathulenol (a major constituent). The study was conducted in part to provide evidence supporting the ethnobotanical use of the leaves of this species. MATERIAL AND METHODS The essential oil (EOPG) was extracted from the leaves of P. guineense by hydrodistillation and analysed by gas chromatography-mass spectrometry (GC-MS). The major compound, spathulenol (PG-1), was isolated in a chromatographic column and characterized by nuclear magnetic resonance (NMR). EOPG and PG-1 were evaluated in vitro for antioxidant activity by DPPH, ABTS and MDA methods; anti-inflammatory potential was assessed using two models, including pleurisy and oedema, in mice. The impact of EOPG and PG-1 on cell proliferation was determined via spectrophotometric quantification of the cellular protein content using a sulforhodamine B assay, and anti-Mycobacterium tuberculosis activity was determined using the REMA method. RESULTS A total of 38 components were identified from the EOPG, with the sesquiterpenic alcohol spathulenol (PG-1) (80.7%) being the major constituent. EOPG and PG-1 exhibited the highest antioxidant activities in the DPPH and MDA system compared with reference standard, with IC50 values ranging from 26.13 to 85.60μg/mL. Oral administration of EOPG and PG-1 showed significant inhibition in the Cg-induced mice paw oedema and pleurisy model. The EOPG (GI50 = 0.89μg/mL) and PG-1 (GI50 = 49.30μg/mL) were particularly effective against the ovarian cancer cell line. Both showed moderate antimycobacterial activity. CONCLUSION For the first time, this study demonstrated the antioxidant, anti-inflammatory, antiproliferative and antimycobacterial properties of the essential oil of P. guineense (leaves were collected in Dourados-MS) and spathulenol, collaborating the etnhopharmacologycal use of this plant due to its an anti-inflammatory effect.

Abstract
We describe the case of an African woman who was diagnosed with ketosis-prone diabetes with diabetes-associated autoantibodies, after being admitted for diabetic ketoacidosis (DKA) precipitated by her first presentation of systemic lupus erythematosus (SLE). She had a seven-year history of recurrent gestational diabetes (GDM) not requiring insulin therapy, with return to normoglycaemia after each pregnancy. This might have suggested that she had now developed type 2 diabetes (T2D). However, the diagnosis of SLE prompted testing for an autoimmune aetiology for the diabetes, and she was found to have a very high titre of GAD antibodies. Typical type 1 diabetes (T1D) was thought unlikely due to the long preceding history of GDM. Latent autoimmune diabetes of adults (LADA) was considered, but ruled out as she required insulin therapy from diagnosis. The challenge of identifying the type of diabetes when clinical features overlap the various diabetes categories is discussed. This is the first report of autoimmune ketosis-prone diabetes (KPD) presenting with new onset of SLE.

Abstract
The present study investigates the effect of hesperidin; a flavonone commonly found in citrus fruits, on the ectoenzymes (ectonucleotidase and ecto-adenosine deaminase) activity, cell viability, apoptosis, cell cycle arrest and reactive oxygen species production in peripheral blood mononuclear cells (PBMCs) from rat model of pleurisy. Wistar rats were pretreated with either saline or hesperidin (80mg/kg) by oral gavage for 21days and injected intrapleurally with 2% carrageenan or saline on the 22nd day. PBMCs were subsequently prepared after 4h of carrageenan induction. The results revealed that hesperidin may exhibit its anti-inflammatory effects through possible modulation of ectonucleotidase (E-NTPDase) and ecto-adenosine deaminase (E-ADA) activities, reduction of intracellular reactive oxygen species, prevention of DNA damage and modulation of apoptosis as well as activation of cell cycle arrest. This study suggests some possible underlying anti-inflammatory mechanisms of hesperidin on PBMCs in acute inflammatory condition. Furthermore, hesperidin may minimize oxidative injury mediated pleurisy in rat.

Abstract
Tuberculous pleurisy (PLTB) is a common form of extrapulmonary tuberculosis. It often resolves without chemotherapy being hence considered a rather benign manifestation of the disease. Patients with PLTB mount an effective anti-mycobacterial response, unlike those with active pulmonary TB (pTB) that were shown to present an imbalance in plasma immune and endocrine mediators. In this work, we explored whether expression of the active isoform of the glucocorticoid receptor (hGRα) in the context of the inflammatory-anti-inflammatory responses of TB patients may be associated to microRNA levels. As expected, the inflammatory response triggered in patients coexists with increased circulating cortisol and altered hGRα levels in the peripheral blood mononuclear cells. However, while hGRα expression is significantly downregulated in PLTB, its levels in pTB patients are higher within the control values. These results point out to the existence of an additional mechanism tending to preserve hGRα levels probably to deal with the chronic inflammation observed in pTB. In this regard, we found that miR-30c is strongly downregulated in mononuclear cells of pTB patients compared to PLTB cases, showing an expression profile opposite to that seen with hGRα. Interestingly, low levels of miR-30c are specific for this active form of TB, as its expression is not altered in mononuclear cells from either healthy controls or patients with tuberculous or non-tuberculous pleurisy. Moreover, miR-30c and hGRα also showed an inverse expression pattern in M. tuberculosis-stimulated THP-1 macrophage cultures. In sum, our studies identify miR-30c as a specific correlate of pulmonary manifestations of TB, potentially involved in the altered glucocorticoid sensitivity observed in these patients.

Abstract
Background Xanthogranulomatous pyelonephritis is a rare and serious manifestation of chronic kidney inflammation that can be life-threatening if not recognized and treated appropriately, often with antibiotics and surgery. Affected patients are most commonly females in their fifth or sixth decade of life with a background of obstructive uropathy, nephrolithiasis, or recurrent urinary tract infections who present with vague nonspecific symptoms. Case presentation A 43-year-old woman of Russian ethnicity with a history of nephrolithiasis presented to our emergency department with new left-sided pleuritic chest pain amid a 6-week history of constitutional symptoms including fevers, night sweats, and 7 kg of weight loss. Workup for acute coronary syndrome and pulmonary embolism in our emergency department was negative. Given that she was clinically unwell, she was admitted to internal medicine to expedite workup for the cause of her symptoms. A broad differential diagnosis for various infectious, inflammatory/autoimmune, and neoplastic processes was considered. Based on classic radiographic and histopathologic findings, she was ultimately diagnosed with xanthogranulomatous pyelonephritis of her left kidney, which was a direct consequence of chronic inflammation. This inflammation exhibited spread to local tissues and across her left hemidiaphragm, resulting in a unilateral pleural effusion which explained her chest discomfort. She was treated with antibiotics administered intravenously and urgent total nephrectomy with a good functional outcome. Conclusions Our case illustrates an uncommon but clinically important do-not-miss diagnosis that underlies a common clinical presentation of pleuritic chest pain. The case underscores the importance of maintaining a broad differential diagnosis and organized approach when treating patients with undifferentiated clinical presentations.

Abstract
Background Isolation of M. tuberculosis (MTB) is required in cases of Tuberculous pleural effusion (TBPE) for confirming diagnosis and successful therapy based on drug sensitivity test. Several studies have focused on predictors of MTB culture positivity in TBPE. However, the clinical role of loculated TBPE as a predictor of MTB cultivation from TBPE remains unclear. The aim of this study was to examine possible predictors including loculation of TBPE of MTB culture positivity in TBPE. Methods We retrospectively examined associations between clinical, radiological, microbiological, and laboratory characteristics and positive MTB culture from TBPE to determine a potent predictor of culture positivity. Results From January 2011 to August 2015, 232 patients with TBPE were identified. Of these, 219 were finally analyzed. Among them, 69 (31.5%) were culture positive for MTB in TBPE and 86 (39.3%) had loculated TBPE. In multivariate logistic regression analysis, the loculation of TBPE was independently associated with culture positivity for MTB in TBPE (adjusted odds ratio [OR], 40.062; 95% confidence interval [CI], 9.355–171.556; p<0.001). In contrast, the lymphocyte percentage of TBPE (adjusted OR, 0.934; 95% CI, 0.899–0.971; p=0.001) was inversely associated with culture positivity for MTB in TBPE. Conclusion In clinical practice, identification of loculation in TBPE is easy, reliable to measure, not uncommon and may be helpful to predict the possibility of positive mycobacterial culture.

Abstract
Chest pain represents one of the most frequent symptoms of pulmonary diseases, in addition to dyspnea and cough. The broad differential diagnostics include the intensely painful but prognostically benign acute pleurisy as well as potentially life-threatening events, such as acute pulmonary embolism or malignant chest diseases. Primary spontaneous pneumothorax is characterized by acute chest pain. Pain associated with a respiratory infection, such as pneumonia rarely poses a difficult diagnostic problem. Painful diseases of the lungs can be differentiated in an initial approach by asking the patient if the pain is related to breathing, which is characteristic of pleuritic chest diseases. Pulmonary hypertension, lung cancer and mesothelioma show more constant pain unrelated to respiratory movements. It is most important to differentiate pain associated with acute exacerbation of chronic obstructive pulmonary disease (COPD), whereby a possible cardiac comorbidity, such as acute coronary syndrome (ACS) should always be considered.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaves of Allophylus edulis (A. St.-Hil., A. Juss. & Cambess.) Radlk. (Sapindaceae) are traditionally used as a natural anti-inflammatory agent; however, there are no scientific studies demonstrating its activity essential oil. The content of essential oil in A. edulis may be the chemical basis to explain its ethnobotanical uses, since infusions of this plant are used to treat inflammation in the traditional medicine in Brazil. AIM OF THE STUDY This study evaluated the anti-inflammatory, antioxidant and anti-mycobacterial activities of the essential oil (EOAE) and viridiflorol, its main compound. MATERIAL AND METHODS Essential oil from fresh leaves of A. edulis (EOAE) was obtained by hydrodistillation in a Clevenger-type apparatus. Forty-one compounds, accounting for 99.10% of the oil, were identified by gas chromatography-mass spectrometry (GC-MS). The major constituent of the oil was viridiflorol (30.88%). Additionally, the essential oil and viridiflorol were evaluated using an in vitro test against Mycobacterium tuberculosis and in 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays. Both EOAE (30 and 100mg/kg) and viridiflorol (3 and 30mg/kg) by oral administration were assayed in carrageenan-induced mice paw oedema and pleurisy using subcutaneous injection of dexamethasone (0.5mg/kg) as the positive control. RESULTS EOAE and viridiflorol displayed moderate in vitro activity in the M. tuberculosis assay. In all tests, EOAE and viridiflorol showed moderate antioxidant activity compared with reference standards. Both EOAE and viridiflorol showed significant inhibition in the carrageenan-induced mice paw oedema via oral administration of the oil (30 and 100mg/kg), compound (3 and 30mg/kg), and subcutaneous injection of dexamethasone (0.5mg/kg, reference drug). Also EOAE and viridiflorol significantly inhibited carrageenan (Cg) induced pleurisy, reducing the migration of total leucocytes in mice by 62±5% (30mg/kg of oil), 35±8% (100mg/kg of oil), 71±5% (3mg/kg of viridiflorol) and 57±3% (30mg/kg of viridiflorol). CONCLUSION For the first time, the results from this work corroborate the literature, showing that A. edulis can be used as a natural anti-inflammatory agent. Moreover, both EOAE and viridiflorol exhibited biological activities, such as anti-mycobacterial, anti-inflammatory and antioxidant activity.

Abstract
Leukotrienes (LTs) are lipid mediators derived from arachidonic acid (AA) involved in a number of autoimmune/inflammatory disorders including asthma, allergic rhinitis and cardiovascular diseases. Salvinorin A (SA), a diterpene isolated from the hallucinogenic plant Salvia divinorum, is a well-established analgesic compound, but its anti-inflammatory properties are under-researched and its effects on LT production is unknown to date. Here, we studied the possible effect of SA on LT production and verified its actions on experimental models of inflammation in which LTs play a prominent role. Peritoneal macrophages (PM) stimulated by calcium ionophore A23187 were chosen as in vitro system to evaluate the effect of SA on LT production. Zymosan-induced peritonitis in mice and carrageenan-induced pleurisy in rats were selected as LT-related models to evaluate the effect of SA on inflammation as well as on LT biosynthesis. SA inhibited, in a concentration-dependent manner, A23187-induced LTB4 biosynthesis in isolated PM. In zymosan-induced peritonitis, SA inhibited cell infiltration, myeloperoxidase activity, vascular permeability and LTC4 production in the peritoneal cavity without decreasing the production of prostaglandin E2. In carrageenan-induced pleurisy in rats, a more sophisticated model of acute inflammation related to LTs, SA significantly inhibited LTB4 production in the inflammatory exudates, along with reducing the phlogistic process in the lung. In conclusion, SA inhibited LT production and it was effective in experimental models of inflammation in which LTs play a pivotal role. SA might be considered as a lead compound for the development of drugs useful in LTs-related diseases.

Abstract
INTRODUCTION Haemorragic pleurisy is fairly common. The etiology is dominated by tumors and tuberculosis. The rupture of intra-thoracic vessels into the pleural cavity is a much rarer cause and the diagnosis is often delayed. OBSERVATION A 77-year-old patient without previously known hypertension was hospitalized for investigation of a fluid density opacity occupying the entire left hemithorax. Thoracentesis revealed a non-coagulable haemorrhagic fluid. A computed tomography scan showed a Stanford type B aortic dissection. The patient was given anti-hypertensive treatment for one year. CONCLUSIONS Aortic dissection remains among the diagnoses to consider in the case of a haemorrhagic pleural effusion despite absence of the usual suggestive symptoms.

Abstract
Multiple myeloma is a malignant proliferation of plasma cells, mainly affecting the bone marrow. It rarely occurs in young patients. The medical observation study reveals multiple myeloma discovered through a purulent pleurisy in a 28-year-old subject. This patient was admitted to the pneumology service of the Mohamed V military hospital in Rabat for a fever and dyspnea evolving into a context of poor general condition. Clinical examination found a right pleural fluid effusion syndrome. The pleural puncture reveals a germ-free exudative purulent fluid without plasma cells. The myeloma diagnosis was suspected due to the combination of an aplastic normochromic normocytic anemia at 4.5g/dL of hemoglobin, an accelerated erythrocyte sedimentation rate, hypercalcemia, renal failure and osteolytic lesions located mainly in the skull and pelvis area, oriented by electrophoresis and serum protein immunosubstraction revealing a narrow peak in monoclonal beta-2 globulin at 70.56g/L with a lambda monoclonal gammopathy with immunoglobulin G, and confirmed by the myelogram showing a 74% rate of bone marrow plasma cells. The occurrence of myeloma at a young age is rare and the purulent pleurisy without plasma cells is a rare form of presentation and represents a poor prognosis.

Abstract
This study was conducted to evaluate the impact of implementation of an automated liquid culture system on the diagnosis of tuberculous pleurisy in an HIV-uninfected patient population. We retrospectively compared the culture yield, time to positivity, and contamination rate of pleural effusion samples in the BACTEC Mycobacteria Growth Indicator Tube 960 (MGIT) and Ogawa media among patients with tuberculous pleurisy. Out of 104 effusion samples, 43 (41.3%) were culture positive on either the MGIT or the Ogawa media. The culture yield of MGIT was higher (40.4%, 42/104) than that of Ogawa media (18.3%, 19/104) (P<0.001). One of the samples was positive only on the Ogawa medium. The median time to positivity was faster in the MGIT (18 days, range 8-32 days) than in the Ogawa media (37 days, range 20-59 days) (P<0.001). No contamination or growth of nontuberculous mycobacterium was observed on either of the culture media. In conclusion, the automated liquid culture system could provide approximately twice as high yields and fast results in effusion culture, compared to solid media. Supplemental solid media may have a limited impact on maximizing sensitivity in effusion culture; however, further studies are required.

Abstract
Early diagnosis of extrapulmonary tuberculosis (EP-TB) is essential. However, diagnosis of EP-TB is difficult. We evaluated the diagnostic utility of an interferon-gamma release assay (IGRA) in diagnosing active EP-TB among suspected patients in Korea. We retrospectively reviewed the clinical records of all patients with suspected EP-TB at Gangnam Severance Hospital in Seoul, Korea. Of the 418 patients with suspected EP-TB, 324 had active EP-TB. The tuberculosis (TB) group had a higher percentage of positive IGRAs (70.2%, 33/47) than the non-TB group (33.3%, 3/9) (P=0.034). The IGRA sensitivity and specificity were 70.2% (63.7-74.8%) and 66.7% (32.9-90.6%), respectively. The sensitivity and specificity of IGRAs in patients with TB lymphadenitis were 81.8% (61.4-90.4%) and 80.0% (35.1-98.9%), but 38.5% (31.2-45.7%) and 50.0% (2.7-97.3%) in patients with TB pleurisy. The diagnostic performance of IGRAs may vary depending on the site of EP-TB involvement. IGRA was potentially valuable for diagnosis of active EP-TB in TB lymphadenopathy.

Abstract
Diethylcarbamazine citrate (DEC) is widely used to treat lymphatic filariasis and Tropical Pulmonary Eosinophilia. A number of studies have reported a possible role in the host immune system, but exactly how DEC exerts this effect is still unknown. The present study reports the effects of DEC pretreatment on NF-κB regulation using the pleurisy model induced by carrageenan. Swiss male mice (Mus musculus) were divided into four experimental groups: control (SAL); carrageenan (CAR); diethylcarbamazine (DEC) and curcumin (CUR). The animals were pretreated with DEC (50mg/kg, v.o), CUR (50mg/kg, i.p) or distilled water for three consecutive days before pleurisy. One way analysis of variance (ANOVA) was performed by Tukey post-hoc test, and values were considered statistically significant when p<0.05. DEC pretreatment reduced tissue damage and the production of inflammatory markers, such as NO, iNOS, PGE2, COX-2, and PARP induced by carrageenan. Similarly, a known inhibitor of NF-κB pathway (curcumin) was also able to reduce these parameters. Like curcumin, DEC prevents NF-κB activation by reducing NF-κB p65 phosphorylation and IκBα degradation. DEC prevented NF-κB activation via p38 MAPK, but did not interfere in the ERK pathway in this experimental model. However, further studies should be developed to confirm this hypothesis. These findings suggest that DEC could be a promising drug for inflammatory disorders, especially in pulmonary diseases such as Acute Lung Inflammation, due its high anti-inflammatory potential which prevents NF-κB activation.

Abstract
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.

Abstract
The objective of the present paper is to describe the clinical and computed tomography features of 'explosive pleuritis', an entity first named by Braman and Donat in 1986, and to propose a case definition. A case report of a previously healthy, 45-year-old man admitted to hospital with acute onset pleuritic chest pain is presented. The patient arrived at the emergency room at 15:00 in mild respiratory distress; the initial chest x-ray revealed a small right lower lobe effusion. The subsequent clinical course in hospital was dramatic. Within 18 h of admission, he developed severe respiratory distress with oxygen desaturation to 83% on room air and dullness of the right lung field. A repeat chest x-ray, taken the morning after admission, revealed complete opacification of the right hemithorax. A computed tomography scan of the thorax demonstrated a massive pleural effusion with compression of pulmonary tissue and mediastinal shift. Pleural fluid biochemical analysis revealed the following concentrations: glucose 3.5 mmol/L, lactate dehydrogenase 1550 U/L, protein 56.98 g/L, amylase 68 U/L and white blood cell count 600 cells/mL. The pleural fluid cultures demonstrated light growth of coagulase-negative staphylococcus and viridans streptococcus, and very light growth of Candida albicans. Cytology was negative for malignant cells. Thoracotomy was performed, which demonstrated a loculated parapneumonic effusion that required decortication. The patient responded favourably to the empirical administration of intravenous levofloxacin and ceftriaxone, and conservative surgical methods in the management of the empyema. This report also discusses the patient's rapidly progressing pleural effusion and offers a potential case definition for explosive pleuritis. Explosive pleuritis is a medical emergency defined by the rapid development of a pleural effusion involving more than 90% of the hemithorax over 24 h, which causes compression of pulmonary tissue and mediastinal shift to the contralateral side.

Abstract
BACKGROUND Differential diagnosis between tuberculous pleurisy (TBP) and non- tuberculosis pleural effusion represents a critically important clinical problem. In recent years, several noninvasive methods have been found for diagnosis of tuberculous pleurisy. This study aimed to evaluate the value of detection of the genome of Mycobacterium tuberculosis (MTB) by polymerase chain reaction (PCR) method for the diagnosis of tuberculous pleurisy and compare the results with those of conventional methods. MATERIALS AND METHODS In this cross-sectional study, we studied 62 patients (42 men and 20 women) with pleural effusion in Ghaem Hospital, affiliated to Mashhad University of Medical Sciences from January 2006 to June 2007. RESULTS A total of 20 patients had tuberculous pleurisy (45.4%), 15 patients had malignant pleural effusion (34%), 3 patients had pleural effusion with various "non-tuberculosis non-malignant" etiologies (6.8%) and 6 patients had transudative pleural effusion (13.6). The sensitivity, specificity, positive predictive value and negative predictive value of PCR in tuberculous pleurisy were 85%, 100%, 100% and 88.8%, respectively. CONCLUSION The value of PCR test and pleural biopsy was similar in the diagnosis of TBP. However, PCR detected MTB in pleural effusion when conventional pleural biopsy failed to do so.
