OBJECTIVE: The aim of this study was to assess the efficacy and safety of intrapleural perfusion with hyperthermic chemotherapy (IPHC) in treating malignant pleural effusion (MPE) compared to normothermic chemoperfusion of the pleural cavity (NCPC), and to investigate the better treatment to control MPE. METHODS: Malignant pleural effusion patients were enrolled in the study and treated with NCPC or IPHC under video-assisted thoracoscopic surgery (VATS). The chest drainage duration, clinical characteristics, and recurrence time of pleural effusion of patients were collected for statistical analysis. The chi-squared test and the Fisher's exact test were applied to compare the distribution differences in categorical variables. Progression-free survival (PFS) was estimated by the Kaplan-Meier method and was compared by the log-rank test. The survival analysis was performed using the Cox proportional hazards method. RESULTS: A total of 37 MPE patients were enrolled in this study. Twenty-seven patients received NCPC and 10 patients received IPHC under VATS. Significant differences were found in pathological types (p = 0.011), chest drainage duration (p = 0.005), and remission rate (p = 0.009) between two different treatment groups. The chest drainage duration of IPHC under VATS was shorter than the NCPC group (t = 2.969, p = 0.005). The remission rate of MPE in IPHC group was better than the NCPC one (OR = 0.031, 95% CI: 0.002-0.507, p = 0.015). The result of the Kaplan-Meier method showed that IPHC group could significantly prolong the PFS of patients with MPE compared to NCPC group (log-rank p = 0.002). Univariate cox regression analysis showed that patients with MPE in the IPHC group presented significant longer PFS than the NCPC group (HR = 0.264, 95% CI: 0.098-0.713, p = 0.009). Multivariate cox regression analysis further verified this conclusion (HR = 0.268, 95% CI: 0.096-0.753, p = 0.012). CONCLUSION: Compared to the NCPC, the IPHC under VATS presents a better control effect on MPE, shorter tube placement time, and longer complete remission time. For this reason, we recommend IPHC under VATS as the first-line treatment for patients with MPE those who can tolerate minimally invasive surgery.

Soft tissue tumors are a highly heterogeneous group of lesions with varied clinical presentation. The majority is primary tumors and metastatic tumors are very rare. Malignant pleural mesothelioma presenting as a soft tissue mass at a distant site is even rarer and can cause diagnostic challenges both clinically and pathologically. We report a case of malignant pleural mesothelioma presenting as a soft tissue mass in the left thigh. A 59-year-old man, non-smoker, working in a cement factory since 30 years presented with complains of difficulty in walking since 1½ months. Review of his previous medical records revealed malignant pleural mesothelioma, which was diagnosed 9 months before. He had denied chemotherapy and was on Ayurvedic medication. The lesion involved the adjacent intercostal muscles. Few enlarged lymph nodes were noted in mediastinal and cervical regions. Biopsy of left supraclavicular and right cervical lymph nodes showed metastases. Metastasis from malignant pleural mesothelioma to the thigh was confirmed by immunohistochemistry. The tumor was positive for CK5/6, CK7, Calretinin and vimentin and immunonegative for CEA, Napsin A and TTF 1.

OBJECTIVES: To evaluate the outcomes of thoracoscopic surgery for intractable secondary spontaneous pneumothorax (SSP) under local anesthesia in high-risk patients and report intraoperative findings useful for identifying air leakage points. METHODS: We analyzed outcomes of 14 consecutive thoracoscopic operations under local anesthesia for high-risk SSP from 2015 to 2019. Suspicious lesions were determined based on intraoperative direct or indirect detections. Direct detection involved identifying pleural fistulas or air bubbles. Indirect detection involved finding thin and transparent bullae without any other suspicious lesions. Identifications of culprit lesions were confirmed by arrest or significant decrease in air leakage after surgical repair. All surgical repairs were followed by immediate single pleurodesis for a definitive cure and prevention of recurrence. Success was defined as the removal of the thoracic tube by surgical repair combined with immediate postoperative single pleurodesis. RESULTS: The main underlying pulmonary diseases were emphysema (n = 7), carcinoma (n = 3), interstitial pneumonia (IP) (n = 3), and nontuberculous mycobacterial infection (n = 1). A leakage point was identified in 13 cases (six on direct and seven on indirect detections). Success was achieved in nine cases (four on direct and five on indirect detections). Adverse events included one case of acute exacerbation of IP and one case of carbon dioxide narcosis. CONCLUSION: Thoracoscopic surgery under local anesthesia can be the worthwhile definitive modality, among few remaining treatments, for highly fragile patients with SSP. Detecting air leakage directly and the presence of thin and transparent bullae without any other suspicious lesions can be clues for identifying culprit lesions.

OBJECTIVES: Malignant pleural effusion (MPE) has a poor prognosis. Most patients are treated with tube thoracostomy and sclerotherapy, although its success rate is around 64%. We have investigated intrapleural perfusion with hyperthermic chemotherapy (IPHC) using cisplatin in a study with a pharmacokinetic evaluation. METHODS: Patients with MPE, performance status of 0-1, possibility of good lung expansion and Cr<1.2mg/dL were treated with IPHC. The circuit was filled with 2000mL of normal saline containing cisplatin at a dose of 80mg/m2. Under video-assisted thoracoscopic surgery, the thoracic cavity was filled and perfused at a speed of approximately 1L/min at a temperature of 43°C for 1h. Perfusion solution and plasma samples were periodically collected, and concentrations of protein-unbound (free) platinum, which was the active derivative of cisplatin, and total platinum were determined by flameless atomic absorption spectrometry. RESULTS: Twenty patients with MPE (8 lung cancers, 7 mesotheliomas, and 5 others) were enrolled in this study. Rate of free platinum concentration relative to total platinum concentration in perfusion solution after 1hr IPHC at 43°C was 61.1±12.9%. Area under curve (AUC) of free platinum in the pleural space was calculated to be 26.3µg/mLxh, resulting in complete control of pleural effusion for 3 months after IHPC in all cases (95% confidence interval: 83-100%). While, absorption rate of total platinum from the pleural space was 33.8±17.0% (27.4±13.6mg/m2), and the maximum concentration of total platinum in serum was low, 0.66±0.31µg/mL, resulting in controllable side effects; grade 1 renal toxicity: 6 patients, grade 1 emesis: 7 patients. CONCLUSIONS: IPHC with cisplatin showed favorable pharmacokinetic profiles for an optional treatment to control malignant pleural effusion.

BACKGROUND: Medical thoracoscopy (MT) is a minimally invasive, endoscopic procedure for exploration of the pleural cavity under conscious sedation and local anesthesia. MT has been performed at the Seoul National University Hospital since February 2014. This paper summarizes the findings and outcomes of MT cases at this hospital. METHODS: Patients who had undergone MT were enrolled in the study. MT was performed by pulmonologists, using both rigid and semi-rigid thoracoscopes. During the procedure, patients were under conscious sedation with fentanyl and midazolam. Medical records were reviewed for clinical data. RESULTS: From February 2014 to January 2016, 50 procedures (47 cases) were performed (diagnostic MT, 26 cases; therapeutic MT, 24 cases). The median age of patients was 66 years (59–73 years), and 38 patients (80.9%) were male. The median procedure duration from initial incision to insertion of the chest tube was 37 minutes. The median doses of fentanyl and midazolam were 50 µg and 5 mg, respectively. All procedures were performed without unexpected events. Of the 26 cases of pleural disease with an unknown cause, 19 were successfully diagnosed using MT. Additionally, diagnostic MT provided clinically useful information in the other six patients. Therapeutic MT was very effective for treatment of malignant pleural effusion or empyema. The median number of days with chest tube drainage was 6 (3 days for diagnostic MT and 8 days for therapeutic MT). CONCLUSION: MT is a useful and necessary procedure for both diagnosis and treatment of pleural diseases.

ETHNOPHARMACOLOGICAL RELEVANCE: Ageratum conyzoides Linn (Asteraceae), a tropical plant that is very common in West Africa and some parts of Asia and South America, has been used to treat inflammatory disorders. In Brazil, teas made from A. conyzoides L. are used as anti-inflammatory, analgesic and anti-diarrheic agents. Therefore, it is necessary to study the mechanism of anti-inflammatory action of A. conyzoides L. to support its medicinal use for treating inflammatory conditions. These studies will also support the development of effective pharmacological agents with potent anti-inflammatory properties. AIM OF THE STUDY: To evaluate the anti-inflammatory effects of the crude extract (CE), its derived fractions: ethanol (EtOH-F), hexane (HEX-F), ethyl acetate (EtOAc-F) and dichloromethane (DCM-F) and isolated compounds, such as 5'-methoxy nobiletin (MeONOB), 1,2-benzopyrone and eupalestin, which are obtained from the aerial parts of A. conyzoides L. MATERIALS AND METHODS: These evaluations were performed using an animal model of inflammation induced by carrageenan. The following inflammatory parameters were analysed: leukocyte influx, protein concentration of the exudate, myeloperoxidase (MPO), adenosine deaminase (ADA) and nitric oxide metabolites (NOx) concentrations, interleukin 10 (IL-10), interleukin 17A (IL-17A), interleukin 6 (IL-6), tumor necrosis factor (TNF), interferon gamma (IFN-γ) and phosphorylation of p65 subunit of NF-κB (p-p65 NF-κB), p38 mitogen-activated protein kinases (p-p38 MAPK) were also analysed. RESULTS: CE, its EtOH-F, HEX-F, EtOAc-F and DCM-F and the isolated compounds, including MeONOB, 1,2-benzopyrone and eupalestin, significantly reduced leukocyte influx, protein concentration of the exudate, MPO, ADA, and NOx concentrations (p<0.05). CE, EtOH-F and isolated compounds significantly reduced IL-17A, IL-6, TNF and IFN-γ levels (p<0.05). CE, EtOH-F and isolated compound 1,2-benzopyrone also increased IL-10 levels (p<0.05). Isolated compounds, MeONOB, 1,2-benzopyrone and eupalestin, reduced p-p65 NF-κB and p-p38 MAPK (p<0.01). CONCLUSIONS: This study demonstrates that A. conyzoides L. exerts its important anti-inflammatory properties by inhibiting leukocyte influx and protein concentration of the exudate, as well as reducing the levels of several pro-inflammatory mediators. The anti-inflammatory action of A. conyzoides L. may be because of the inhibition of p65 NF-κB and MAPK activation by the isolated compounds.

The inability to maintain filarial nematodes in long-term in vitro culture greatly limits research into the basic biology of these parasites and hinders in vitro screening of novel anti-filarial agents. In this study, we sought to characterize nutrients that promote the long-term survival of filarial worms in vitro. Using microfilariae (MF) obtained from gerbils infected with Litomosoides sigmodontis, a filarial parasite of rodents, we found that Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% fetal bovine serum (FBS) resulted in MF survival of only 5 days. However, co-culturing MF with a mouse endothelial cell line (EOMA) enabled survival for 40 days. Culturing EOMA cells in transwell plates extended MF survival to the same degree as direct co-culture, suggesting that the factors microfilariae require are soluble in nature. Heat inactivation of EOMA conditioned media at 56 °C reduced MF survival by approximately 50%, and heat inactivation at 100 °C reduced survival to 3 days, demonstrating that both heat labile and heat stable factors are involved. EOMA cells require FBS to produce these factors, as conditioned media collected from EOMA cells grown in the absence of FBS failed to prolong survival. The removal of lipids also abrogated survival, indicating MF are likely utilizing lipid factors released by EOMA cells. Dialysis experiments demonstrate that at least some of the required factors are between 0.1 and 1 kDa in size. Importantly, L. sigmodontis adult worms also show significantly extended survival when cultured in EOMA conditioned media. Together, these results suggest that EOMA-produced factors include lipid-containing molecules, heat labile molecules (likely a protein), and micronutrients between 0.1 and 1 kDa in size. These studies have established a cell-free approach to maintaining MF and adult stage filarial worms in long-term in vitro culture and have taken important steps towards biochemically characterizing host-derived nutrients required for parasite survival.

In the pleural empyema (PE) treatment, not depending on introduction of multiple operative procedures and the medicinal preparations application, some issues remain unsolved, including the infection agents verification, the most rapid bronchial fistula elimination and the lung volume restoration. The EP infection agents spectrum, their sensitivity to preparations were revealed, as well as the enhanced rate of the methicillin-resistant stamms (MRSA) and the microorganisms associations verification. A reduction of the infection agents sensitivity towards "simple" antibacterial preparations was established, so the physicians, treating PE, must prescribe "hard" antibiotics, what enhances its cost.

Campomanesia xanthocarpa (Myrtaceae) is used in Brazilian traditional medicine against fever, diabetes, hypercholesteremic, obesity, and urinary diseases. In the present study, the compounds 2',6'-dihydroxy-3'-methyl-4'-metoxychalcone and 2',4'-dihydroxy-3',5'-dimethyl-6'-methoxychalcone were identified for the first time in leaves of the C. xanthocarpa. These compounds and the hydroethanolic extract (HECX) significantly inhibited paw edema and reduced both leukocyte migration and the leakage of protein into the pleural cavity. No toxicity was detected by HECX in an acute toxicity test.

Malignant fluid, a commonly seen tumor associated complication, mainly includes peritoneal effusion, malignant pleural effusion and pericardial effusion. It can produce huge negative influence on the quality of life of patients and even lead to death. Treatment of malignant effusion is one of the effective measures for improving life expectancy of patients. To evaluate the effect of thermotherapy in combination with intracavitary infusion of Kangai injection in treating malignant pleural effusion, 195 patients who received treatment from April 2010 to October 2014 in the First Affiliated Hospital of Zhengzhou University were selected and divided into an observation group and two control groups (group A and B). The observation group was treated by thermotherapy in combination with intracavitary infusion of kangai injection. Control group A was treated by intracavitary infusion of kangai injection and control group B was treated by hyperthermal perfusion in combination with intracavity chemotherapy. Clinical effects, quality of life, treatment safety and untoward reactions were compared between the groups. It was found that differences of WBC, RBC and PLT levels before and after treatment had no statistical significance comparisons within group and comparisons between groups (P>0.05); hepatic and renal functions of the groups had no remarkable difference before or after treatment (P>0.05). The clinical effect of the observation group was superior to that of control groups A and B (P less than 0.05); the Karnofsky performance status (KPS) score of the observation group was much higher than that of control groups A and B (79.34±10.58 vs 71.11±9.64), but the difference of the ZPS score between groups had no statistical significance (P>0.05). It can be concluded that thermotherapy in combination with intracavitary infusion of traditional Chinese medicine can be safely applied as it has positive effects and remarkably improves quality of life, therefore it is clinically worth promoting.

ETHNOPHARMACOLOGICAL RELEVANCE: Senecio brasiliensis (Spreng) Less (S. brasiliensis), known as "Flor-das-almas", "Margaridinha" or "Maria mole", is used in folk medicine as an anti-inflammatory and to treat gastric ulcers and stomach pain. While the Senecio genus has been widely studied for its pharmacological activities to support its use in traditional medicine, few studies focus on the anti-inflammatory activities of the species. AIM OF THE STUDY: To investigate the anti-inflammatory activities of S. brasiliensis, a specie native to Brazil, using a murine model of pleurisy induced by carrageenan. MATERIAL AND METHODS: The flowers of S. brasiliensis were air-dried for 3 days and subjected to ethanol (96%) extraction for 7 days to obtain the crude extract (CE). The CE was subjected to acid-base extraction to obtain the alkaloid fraction (AF). The hexane (HEX), dichloromethane (DCM) and ethyl acetate (EtOAc) fractions were obtained by extracting from CE with different solvents. The alkaloids senecionine (Sen), integerrimine (Int) and senecionine N-oxide were obtained from AF by chromatographic fractionation and a mixture of 1,4-, 3,4-, 3,5- and 4,5-dicaffeoylquinic acids (DCQs) were obtained from the EtOAc fraction. The isolated alkaloids were identified through spectroscopic analysis of IR, NMR and LC-MS coupled with electrospray ionization mass spectrometry (ESI-MS), and the dicaffeoylquinic acids through the hierarchical key method. Swiss mice were used in the in vivo experiments. We evaluated the effect of the CE, its derived fractions (AF, HEX, DCM and EtOAc), and the isolated compounds (Sen, Int, N-oxide senecionine, and DCQs) on: leukocyte migration, exudate concentrations, myeloperoxidase (MPO) and adenosine-deaminase (ADA) activities, and tumor necrosis factor-α (TNF-α), interleukin 1ß (IL-1ß) and interleukin 17A levels in the fluid leakage from the pleural cavity using a mouse model of pleurisy induced by carrageenan. The effects of the isolated compounds, Sen, Int, N-oxide senecionine and DCQs, were also analyzed for their ability to inhibit p65 phosphorylation (p-p65) in the nuclear factor-kappa B (NF-κB) pathway in the lung tissue. MPO and ADA were analyzed by colorimetric assays, and the cytokines and protein p65 levels were determined using an enzyme immunoassay (EIA). RESULTS: The CE, its EtOAc and AF fractions, and its isolated compounds (Sen, Int and DCQs), significantly reduced leukocyte migration (P < 0.05), MPO and ADA activities (P < 0.01), and TNF-α (P < 0.05), and IL-17A levels (P < 0.01). The CE, the EtOAc and AF fractions, and the DCQs also decreased IL-1ß levels (P < 0.01). The isolated compounds, Sen, Int and the DCQs, inhibited p65 phosphorylation (NF-κB) (P < 0.05). CONCLUSION: This study demonstrated that S. brasiliensis has important anti-inflammatory properties that are capable of inhibiting activated leukocytes by decreasing neutrophil migration. This effect may be attributed to the inhibition of pro-inflammatory cytokines and the reduction of the NF-κB pathway. The compounds Sen, Int, and DCQs may be responsible for the anti-inflammatory actions of S. brasiliensis.

Acrocomia aculeata, popularly known as "bocaiuva," is widely acknowledged in culinary and traditional medicines to treat cardiovascular diseases, a combined effect with diuretics that are also used for hypertension. However, there are no scientific data published to support its use as functional food and its ethnopharmacological use. This study intended to determine the composition of fatty acids of the pulp oil and evaluate the diuretic action and anti-inflammatory activity of the in natura and microencapsulated oil orally administrated on rats. The obtained results confirm the prevalence of monounsaturated fatty acids (68.51%), especially oleic acid (65.68%±1.05%), in the oil from the bocaiuva pulp. The in natura A. aculeata oil has diuretic (P<.01) and anti-inflammatory potential, which promoted a marked inhibition on the hind paw edema induced by carrageenan (67%±7% after 2 h) (P<.01). In addition, results show that the oral administration of the bocaiuva oil at 300 (P<.05) and 700 (P<.05) mg/kg doses significantly inhibited the leukocyte migration induced by carrageenan to the pleural cavity in rats. The inhibitions equaled 91%±3% and 81%±16%, respectively. The microencapsulated oil also showed antiedematogenic (P<.01) as well as diuretic activities (P<.01). The microencapsulation by complex coacervation was shown to be a technique that favors the bioavailability and preservation of bioactive components of the bocaiuva oil.

The BTS pleural procedures audit collected data over a 2-month period in June and July 2011. In contrast with the 2010 audit, which focussed simply on chest drain insertions, data on all pleural aspirations and local anaesthetic thoracoscopy (LAT) was also collected. Ninety hospitals submitted data, covering a patient population of 33 million. Twenty-one per cent of centres ran a specialist pleural disease clinic, 71% had a nominated chest drain safety lead, and 20% had thoracic surgery on site. Additionally, one-third of centres had a physician-led LAT service.

This study aims to assess and compare copaiba oleoresin of Copaifera multijuga and 0.5% silver nitrate for the induction of pleurodesis in an experimental model. Ninety-six male Wistar rats were divided into three groups: control (0.9% saline solution), copaiba (copaiba oil), and silver nitrate (0.5% silver nitrate). The substances were injected into the right pleural cavity and the alterations were observed macroscopically and microscopically at 24, 48, 72, and 504 h. The value of macroscopic alterations grade and acute inflammatory reaction grade means was higher in the 24 h copaiba group in relation to silver nitrate. Fibrosis and neovascularization means in the visceral pleura were higher in 504 h copaiba group in relation to the silver nitrate group. The grade of the alveolar edema mean was higher in the silver nitrate group in relation to the copaiba group, in which this alteration was not observed. The presence of bronchopneumonia was higher in the 24 h silver nitrate group (n = 4) in relation to the copaiba group (n = 0). In conclusion, both groups promoted pleurodesis, with better results in copaiba group and the silver nitrate group presented greater aggression to the pulmonary parenchyma.

Nutritional research has shifted recently from alleviating nutrient deficiencies to chronic disease prevention. We investigated the activity of indicaxanthin, a bioavailable phytochemical of the betalain class from the edible fruit of Opuntia ficus-indica (L. Miller) in a rat model of acute inflammation. Rat pleurisy was achieved by injection of 0.2 mL of λ-carrageenin in the pleural cavity, and rats were killed 4, 24, and 48 h later; exudates were collected to analyze inflammatory parameters, such as nitric oxide (NO), prostaglandin E(2) (PGE(2)), interleukin-1ß (IL-1ß), and tumor necrosis factor-α (TNF-α); cells recruited in pleura were analyzed for cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) expression, and nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) activation. Indicaxanthin (0.5, 1, or 2 µmol/kg), given orally before carrageenin, time- and dose-dependently, reduced the exudate volume (up to 70%) and the number of leukocytes recruited in the pleural cavity (up to 95%) at 24 h. Pretreatment with indicaxanthin at 2 µmol/kg inhibited the carrageenin-induced release of PGE(2) (91.4%), NO (67.7%), IL-1ß (53.6%), and TNF-α (71.1%), and caused a decrease of IL-1ß (34.5%), TNF-α (81.6%), iNOS (75.2%), and COX2 (87.7%) mRNA, as well as iNOS (71.9%) and COX-2 (65.9%) protein expression, in the recruited leukocytes. Indicaxanthin inhibited time- and dose- dependently the activation of NF-κB, a key transcription factor in the whole inflammatory cascade. A pharmacokinetic study with a single 2 µmol/kg oral administration showed a maximum 0.22 ± 0.02 µmol/L (n = 15) plasma concentration of indicaxanthin, with a half-life of 1.15 ± 0.11 h. When considering the high bioavailability of indicaxanthin in humans, our findings suggest that this dietary pigment has the potential to improve health and prevent inflammation-based disorders.

Metastasis to the lung is the most common place connected with kidney cancer progression. Wherein metastasectomy is accompanied by satisfactory 5- and 10-year survival achieving 49% and 21% respectively. Pleural lesion due to this tumor develops as a part of systemic metastasis and, as a rule, is a consequence of neoplastic spread from lung parenchyma, which indicates a poor prognosis and is an indication for palliative care.

The literature and our own experience were analyzed in multimodal approach to the treatment of patients with malignant pleural mesothelioma (MPM). Survival and quality of life of patients with MPM who underwent multimodal treatment, according to modern standards, are often limited by the occurrence of local recurrences. The value of a number of local therapy methods is still being explored in order to determine the possible side effects as well as the duration of disease-free survival. Photodynamic therapy and intraoperative hyperthermic chemoperfusion of the pleural cavity are the methods of the local treatment of this disease, applied after surgery. These approaches have been investigated separately in several studies, but their efficacy and tolerability is still not clear. The authors wanted to find the best indications for the use of these methods and to assess the immediate and long-term results.
