RESUMEN

The molecular pathways involved in the development of vulvar squamous cell carcinoma (SCC) cancer are not completely known. Nicotinamide N-methyltransferase (NNMT) is a cytosolic enzyme associated with tumorigenesis and metastasis in a variety of cancers. Its role in vulvar cancer has not been studied, previously. Vulvar SCC, high and low grade squamous intraepithelial lesions (SILs) and benign squamous hyperplasia were analysed immunohistochemically. The mean staining score for vulvar SCC was significantly higher than the score for vulvar squamous hyperplasia (p<.001). The mean relapse-free survival for patients with low and high NNMT expression was 41.4 months (95% CI: 25.6-57.2) and 19.8 months (95% CI: 3.0-36.6), respectively (p=.035). The mean disease-specific survival for patients with low and high NNMT expression was 75.8 months (95% CI: 57.5-94.2) and 27.8 months (95% CI 12.2-43.4), respectively (p=.015). Although quite preliminary, this study showed that NNMT expression was elevated in vulvar SCC compared to benign and premalignant lesions. Additionally, elevated NNMT expression was associated with poor survival. Impact StatementWhat is already known on this subject? Nicotinamide N-methyltransferase (NNMT) is a methyltransferase, associated with tumour progression, spread and poor prognosis in a variety of cancers. Its upregulation can lead to DNA hypomethylation, which can in turn result in the activation of proto-oncogenes and deactivation of tumour suppressor genes.What do the results of this study add? Although quite preliminary, this study showed that NNMT expression was elevated in vulvar SCC compared to benign and premalignant lesions. Additionally, elevated NNMT expression was associated with poor survival.What are the implications of these findings for clinical practice and/or further research? NNMT has been regarded as a potential target of cancer therapy and its role in vulvar cancer has not been studied, previously. This is the first study to investigate the expression of NNMT in vulvar cancer and associate NNMT elevation with poor survival. NNMT can further be investigated as a possible target of vulvar cancer therapy.

RESUMEN

BACKGROUND: The objective of this study was to investigate the effects that the application of mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) following tendon repair have on the strength and healing of the tendon and also to examine the possible mechanisms of action that take place. METHODS: The Achilles tendons of 80 rats were repaired and divided into eight groups. Following the repairs, MSCs obtained from humans were injected into the rat tendons in groups 1 and 2, a combination of MSCs from humans and PRP from rats was injected into the tendons in groups 3 and 4, and PRP from rats was injected into the tendons in groups 5 and 6. These procedures all took place simultaneously. Groups 7 and 8 did not receive any injections following the repairs. The rats were sacrificed at the end of the first and second months following the procedures, and biomechanical and histopathological analyses were performed. RESULTS: Inflammatory cell density increased most significantly in the combined group when compared to the first and second months. T he fibroblast density on the tendon repair region was significantly lower in the second-months groups of each intervention compared to their first-month groups (p = 0.001). For the analysis of the maximum tensile breaking force, the behaviors of the groups over time were significant when compared to the control groups (p = 0.0015). Also, the mean maximum breaking force in the combined group was statistically significantly higher at the end of the second month than at the end of the first month (p = 0.0008).

RESUMEN

BACKGROUND: Endometrioid endometrial cancer is the most common histological subtype of endometrial adenocarcinoma. In the FIGO grading scheme, both architectural and nuclear grade are taken into consideration. However, the specific impact of solid growth alone on endometrioid endometrial adenocarcinoma outcome is not well documented. We sought to assess the degree of impact of solid growth on lymphovascular space invasion (LVSI), myometrial invasion, tumor size, FIGO stage, lymph node metastasis (LNM), relapse-free survival (RFS) and disease-specific survival (DSS). METHODS: Paraffin blocks of 269 patients treated for endometrioid endometrial cancer were retrospectively analyzed with morphometry for solid growth percentages. RESULTS: A statistically significant cut-off value of 1% solid growth was found for predicting LNM and advanced stage (III or IV), myometrial invasion and LVSI (p < 0.001) and a cut-off value of 8% was found for predicting adverse survival outcome (p < 0.001). The mean DSS was significantly higher in patients with < 6% solid growth compared to patients with 6-50%, 51-75% and > 75% solid growth (p < 0.001). Although, the mean RFS and DSS were lowest in patients with 51-75% solid growth, this did not reach statistical significance in comparison to 6-50% and > 75% (p > 0.05). CONCLUSION: Although > 75% solid growth was most significantly associated with many of the adverse prognostic factors, this subset did not provide prognostic superiority in predicting adverse survival when compared to subsets within 6-75% solid growth. In conclusion, although no statistically significant difference in survival was found among subdivisions of architectural grades 2 and 3, solid growth, especially ≥ 8%, appeared to be an independent prognostic factor for survival in patients with early-stage endometrioid endometrial cancer.

RESUMEN

BACKGROUND: Pathological inflammatory syndromes of unknown etiology are commonly observed in ataxia telangiectasia (AT) and Artemis deficiency. Similar inflammatory manifestations also exist in patients with STING-associated vasculopathy in infancy (SAVI). OBJECTIVE: We sought to test the hypothesis that the inflammation-associated manifestations observed in patients with AT and Artemis deficiency stem from increased type I IFN signature leading to neutrophil-mediated pathological damage. METHODS: Cytokine/protein signatures were determined by ELISA, cytometric bead array, or quantitative PCR. Stat1 phosphorylation levels were determined by flow cytometry. DNA species accumulating in the cytosol of patients' cells were quantified microscopically and flow cytometrically. Propensity of isolated polymorhonuclear granulocytes to form neutrophil extracellular traps (NETs) was determined using fluorescence microscopy and picogreen assay. Neutrophil reactive oxygen species levels and mitochondrial stress were assayed using fluorogenic probes, microscopy, and flow cytometry. RESULTS: Type I and III IFN signatures were elevated in plasma and peripheral blood cells of patients with AT, Artemis deficiency, and SAVI. Chronic IFN production stemmed from the accumulation of DNA in the cytoplasm of AT and Artemis-deficient cells. Neutrophils isolated from patients spontaneously produced NETs and displayed indicators of oxidative and mitochondrial stress, supportive of their NETotic tendencies. A similar phenomenon was also observed in neutrophils from healthy controls exposed to patient plasma samples or exogeneous IFN-α. CONCLUSIONS: Type I IFN-mediated neutrophil activation and NET formation may contribute to inflammatory manifestations observed in patients with AT, Artemis deficiency, and SAVI. Thus, neutrophils represent a promising target to manage inflammatory syndromes in diseases with active type I IFN signature.

RESUMEN

Background: The aim of this study was to investigate the antifibrinolytic and anti-inflammatory effects of hesperidin, tenoxicam and enoxaparin on intrapleural adhesions in an experimental rat model. Methods: A total of 52 healthy adult male Wistar Albino rats from the same colony were randomly divided into six groups as sham (Group 1), surgical control (Group 2), low-dose hesperidin (Group 3), high-dose hesperidin (Group 4), tenoxicam (Group 5), and enoxaparin (Group 6). All subjects underwent left thoracotomy and except for the sham group, an adhesion model was applied and, postoperatively, the drugs were administered intraperitoneally. On Day 11 postoperatively, the rats were sacrificed and their blood levels of interleukin-1ß and interleukin-10 were examined and they were evaluated for pleural adhesion area, adhesion severity score, mesothelial cell proliferation score, mononuclear cell infiltration score, and macrophage infiltration score in the collagen layer. Results: The lowest adhesion area and adhesion severity score were found in Group 6. There was a statistically significant difference between Group 2 and Group 6 and between Group 3 and Group 6 in terms of both parameters (p=0.04 and p=0.02). As for adhesion area, a statistically significant difference was found between Group 5 and Group 6 (p=0.04). Statistically significant differences were also found between Group 2 and Group 5 in terms of mesothelial cell proliferation scores and between Group 1 and Group 4 in terms of mononuclear cell infiltration scores (p=0.03 and p=0.02). Conclusion: Enoxaparin, tenoxicam, and high-dose hesperidin act at different points to prevent adhesion in rats.

RESUMEN

BACKGROUND: The ubiquitin-proteasome pathway controls the monitoring and degradation of important proteins and is involved in several cellular processes, such as development, differentiation, and transcriptional regulation. Recent evidence has shown that ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1), a member of the deubiquitinating enzyme family that removes ubiquitin from protein substrates, is overexpressed in many types of cancer. AIM: This study thus examined the expression of UCH-L1 in human astrocytoma tissues. MATERIAL AND METHODS: Formalin-fixed, paraffin-embedded astrocytoma samples were obtained from 40 patients, after which histopathological examination, typing, and grading were performed. The study group included 10 histologically normal brain tissues, which served as the control group, and 10 WHO grade II, 10 WHO grade III, and 10 WHO grade IV (glioblastoma) samples. Normal brain tissue samples were obtained from the histologically normal, non-tumoral portion of the pathology specimens. UCH-L1 expression was evaluated using quantitative reverse transcription-polymerase chain reaction and immunohistochemistry. RESULTS: Astrocytoma tissues exhibited higher UCH-L1 expression compared to the control group. UCH-L1 overexpression increased significantly together with the increase in astrocytoma grades (from II to IV). CONCLUSION: UCH-L1 could be a good diagnostic and therapeutic marker for determining astrocytoma development and progression.

RESUMEN

PURPOSE: It is known that the RAS and BRAF mutations are predictive for targeted therapies in treating metastatic colon cancer and negatively affect the prognosis of the disease. However, there are limited studies in early-stage colon cancer about the relationship of this mutational condition with the prognosis and relapse pattern of the disease. In this study, we evaluated the effects of mutational status on the clinical pattern of recurrence and survival in early-stage colon cancer in addition to classical risk factors. METHODS: Patients with early-stage colon cancer at the first time of diagnosis and developing recurrence or metastasis on following up were included in this study. Patients were divided into two groups according to the at the time of relapse RAS/BRAF mutation status: mutant or non-mutant/wild types. Then, mutation analysis was performed again from the early-stage tissue of the patients if available. The relationship between early-stage mutation status and progression-free survival (PFS), overall survival (OS), and relapse pattern was analyzed. RESULTS: The number of patients with mutant and non-mutations in the early stage was 39 and 40, respectively. Mutant and non-mutant patients with stage 3 disease were similar (69% and 70%, respectively). OS (47.27 months vs. 67.53 months; p = 0.02) and PFS (25.12 vs. 38.13 months; p = 0.049) were statistically significantly lower in mutant patients, respectively. Most patients had distant metastases on both sides at recurrence (61.5% vs. 62.5%, respectively). There was no significant difference between mutant and non-mutant patients regarding distant metastasis and local recurrence rates (p = 0.657). A discordance of 11.4% between early-stage and late-stage tissue mutation status. CONCLUSION: The presence of mutation in early-stage colon cancer is associated with shorter OS and PFS. The mutational status did not have a significant effect on the recurrence pattern. Because of the discordance of early-stage and late-stage mutational status, it is recommended to perform mutation analysis from tissue at relapse.

RESUMEN

Extramedullary plasmacytoma (EMP) occurs as a result of abnormal proliferation of plasma cells outside the bone marrow. Breast plasmacytomas are rare. Radiologically, they can be confused with benign and malignant lesions of the breast. It is important to be able to diagnose EMP in the breast since the treatment strategy is different from that of other lesions and allows for the diagnosis and early treatment of multiple myeloma (MM) relapse. We report imaging and clinicopathological findings of an EMP case in which a 65-year-old patient with MM in remission presented with breast masses.

RESUMEN

Background: Mutations in the RAS genes, HRAS, KRAS, and NRAS, are the most common modifications in many types of human tumors and are found in approximately 30% of all human cancers. These mutations are usually found in codons 12, 13, or 61. Methods: The aim of this study is to evaluate mutations in codons 59, 117, and 146 of KRAS and NRAS genes in addition to codons 12,13, and 61 of KRAS gene in lung cancer tissue specimens obtained with bronchoscopy. KRAS and NRAS mutation analyses with pyrosequencing were performed on DNA isolated from formalin-fixed paraffin-embedded (FFPE) tissue samples of 64 patients histopathologically diagnosed as lung cancer after bronchoscopic biopsy. Results: In all, 20 patients (31.2%) had mutations in KRAS gene (8/27 squamous cell carcinoma, 8/11 adenocarcinoma, 3/16 small cell carcinoma, and 1/1 pleomorphic carcinoma). The most common mutation in codon 12 was in c.35G>T (G12V). When the mutation rate of adenocarcinoma (72.7%) and squamous cell carcinoma (22.9%) patients was compared with each other, a statistically significant difference was observed (P = 0.008). There were no mutations in codons 59, 117, or 146 of KRAS and NRAS genes in patients with lung cancer. Conclusion: In this study, we firstly examined mutations in codons 59, 117, and 146 of KRAS and NRAS genes in addition to codons 12, 13, and 61 of KRAS gene in Turkish lung cancer patients both in non-small cell lung cancer and small cell lung cancer. Although no mutation was detected in codons 59, 117, and 146 of KRAS and NRAS genes, the frequency of KRAS gene mutation was higher than the rate of mutation in both Asian and Western countries, and multicenter studies including more cases should be performed to further explore our results.

RESUMEN

In this study, we investigated the application of poly (lactic acid-co-glycolic acid) in the rat Achilles tendon injury model for the prevention or alleviation of peritendinous adhesion and guidance of Achilles tendon regeneration. In the study, 48 rats were used and the rats were randomized by closed envelope method and divided into 4 mating groups in groups of 12. Left Achilles tendons of the non-PLGA-treated control group (groups 1 and 2) were cut and repaired. In the PLGA-treated groups (groups 3 and 4) the left Achilles tendons were cut and repaired, then PLGA bioabsorbable material was wrapped around the repair line. The rats in the 1st and 3rd groups were sacrificed at the end of the 1st month, and the rats in the 2nd and 4th groups at the end of the 2nd month. The degree of tendon adhesion in the Group 3 was lower in comparison with Group 1. Similarly, compared with Group 2, the degree of tendon adhesion in the Group 4 was lower. Inflammatory density, vascularization and fibrosis were higher in the experimental group. When the Group 3 and Group 1, and Group 2 and Group 4 were compared, adhesion length (p = 0.004, p = 0.041), adhesion characteristics (p = 0.049, p = 0.039) and adhesion severity (p = 0.007, p = 0.025) were found have statistically significant tendon healing in the PLGA-treated group, respectively. Significant difference was observed in inflammatory cell density, vascular density and fibrosis for Group 1 and Group 3, (p = 0.027, p = 0.041, p = 0.002), respectively. Similarly, significant difference was observed in inflammatory cell density, vascular density and fibrosis for Group 2 and Group 4, (p = 0.002, p = 0.027, p = 0.011), respectively. As a result, it was considered that poly (lactic acid-co-glycolic acid) material significantly reduces peritendinous adhesions, and this effect could occur with the vascular density, inflammatory density and fibrosis as indicated in histopathological examination. These data suggest that PLGA membrane has good biocompatibility and alleviates tendon adhesion after injury.

RESUMEN

INTRODUCTION: In spite of advances in surgical techniques, the significance of anastomosis leak continues in colorectal surgery. There is no ideal method in spite of all studies and technical advances in this field. Our aim of this study was to use fibroblast growth factor collagen (FGF-C) and antibiotic collagen (AB-C) to increase the rate of anastomosis healing in experimental animals with peritonitis. METHODS: This animal experimental study received ethics committee approval. The animals were divided into three groups of seven animals each; the first group was control, the second group was the fibroblast growth factor collagen group, and the third group was the antibiotic collagen group. Under anesthesia, more than 50% of the colonic lumen was opened 4-5 cm distal to the ileocecal junction to create a defect. Twenty-four hours later, primary anastomosis was performed. The second group had the anastomosis line covered with a cover containing FGF-C. The third group had the anastomosis line covered by material containing AB-C. The experiment was concluded on the postoperative 7th day, and the anastomosis burst pressure, tissue hydroxyproline level, and histopathological assessment were performed. RESULTS: Though the burst pressure was higher in the experimental groups, it was not statistically significant. In the second and third groups, vascular proliferation and fibroblastic activity appeared to be better than in the control group. Hydroxyproline values were statistically significant in the experimental groups compared to the control group. CONCLUSION: FGF-C and AB-C may have potential utility in anastomosis healing, especially in those susceptible to infection due to anastomosis leak.

RESUMEN

OBJECTIVES: This study aimed to determine histopathologic changes in the pelviureteral junction in children with pelviureteral junction obstruction. MATERIAL AND METHODS: Seventeen pelviureteral junction specimens obtained from children were divided into two groups: pelviureteral junction obstruction (n = 7) and control (n = 10). Wall thickness of the pelviureteral junction, tunica muscularis of the pelviureteral junction, uroepithelium thickness of the pelviureteral junction, and collagen thickness of the pelviureteral junction were evaluated in resected pelviureteral junctions in children with pelviureteral junction obstruction. MAIN FINDINGS: The mean wall thickness of the pelviureteral junction, mean tunica muscularis of the pelviureteral junction, and uroepithelium thickness of the pelviureteral junction were not significantly higher than those in the control group. Collagen thickness values in the pelviureteral junction obstruction group were significantly higher than those in the control group. CONCLUSIONS: Our data suggest that wall thickness (tunica muscularis and uroepithelium) was not significantly increased, but collagen thickness of the ureter was increased in the pelviureteral junctions of children with pelviureteral junction obstruction.

RESUMEN

BACKGROUND: Recurrent laryngeal nerve (RLN) injury is an important complication of thyroid surgery. In our study, we aimed to compare the effects of primary repair and polyglycolic acid (PGA) coated tube repair on nerve function and regeneration in RLN cuts in rats. METHODS: Twenty seven rats were used for the study. Group-1 with only nerve cuts, group-2 with primary repair, and group-3 with conduit repair. The study was planned over two-stage surgery. In the first step, nerve defect formation and nerve repair were performed in the same session. In the second step, samples were taken from the subjects for histopathological. RESULTS: Vocal cord mobility was proportionally higher in group-3 than other groups. However, there was no statistically significant difference between the groups (p < 0.239). The mean number of highest axons were detected the group-3. CONCLUSIONS: We think that PGA coated conduit can provide a more accurate orientation of nerve fibers by creating an isolated environment when compared to the primary repair. And this may be the cause of functional improvement in the nerve.

RESUMEN

OBJECTIVES: To investigate pathology awareness in patients applying to a pathology laboratory. Method: This cross-sectional study included 150 patients and patients' relatives. A questionnaire, prepared by the researchers according to the literature, was administered at the Pathology Laboratory, Necmettin Erbakan University, Konya, Turkey on May 2018. RESULTS: Of the participants, 79 (52.7%) were female and 71 (47.3%) were male. The mean age was 39.56±14.16 years old. Ninety-eight (65.3%) of them thought that patients do not have right to choose their pathologist. Of the participants, 24 (16%) did not know that the medical school had to be completed in order to become a pathologist and 73 (48.7%) of them did not know that 4 years postgraduate training was required. Fifty-nine (39.3%) of the participants did not know the pathologists were a medical doctor. While 89 participants (59.4%) had no idea what "frozen section" means, 66 people (44%) did not know that the pathologist uses microscope and 64 (42.7%) of them thought that all diseases could be diagnosed 100% by pathological examination. Forty-six (30.7%) of the participants thought that all specimens are not needed to be examined.  Conclusion: The knowledge and awareness of the participants about the pathology discipline came out to be inadequate.

RESUMEN

Fixed drug eruption (FDE) is a type of drug reaction characterized by localized erythema, hyperpigmentation, and bullous at the same site(s), generally observed following every intake of a causative drug. Delayed-type cellular hypersensitivity (Type IVC) is considered to play a role in FDE etiology. Several antibiotics, barbiturates, oral contraceptives, nonsteroidal anti-inflammatory drugs, laxative-containing phenolphthalein, metronidazole, and quinine are known to be the primary drugs responsible for FDE. Bullous FDE, on the other hand, is a relatively rare form of FDE. Hepatitis B is a significant worldwide health problem, and entecavir is a common nucleoside (deoxyguanosine) analog used for treating hepatitis B; however, it has various side effects, such as lactic acidosis, myalgia, azotemia, hypophosphatemia, headache, diarrhea, pancreatitis, and neuropathy, and, in rare cases, cutaneous drug eruption. Our aim is to present a case of entecavir-associated bullous drug reaction, which has not been reported in the literature. Furthermore, we performed a review of literature to compile previously reported entecavir-associated drug reactions.

RESUMEN

OBJECTIVE: The clinical feature of breast cancer is very heterogeneous because of the variable prognostic factors impact its behaviour. The aim of study is to find the prognostic importance of Ki-67 and to analyse the correlation between Ki-67 index and the other conventional prognostic factors in breast cancer patients. MATERIALS AND METHODS: Between 2010 and 2017, patients with invasive ductal carcinoma who received radiotherapy after surgery were included in study. A single pathologist re-defined of all cases retrospectively. Ki-67 were established three categories based on Ki-67 levels: low (<10%), intermediate (10-25%) and high (>25%). RESULTS: A total of 258 patients were included. 46 of 258 (18%) patients were in low, 82 of 258 (32%) patients were in intermediate and 130 of 258 (50%) patients were in high Ki-67 group. There were no correlations between menopausal status, age, and Ki-67 level. Low-pT stages tended to have low Ki-67 expression (p=0.07). Low-pN stages correlated with low Ki-67 values (p=0.007). Patients with ECE (+) were prone to have higher Ki-67 values (p=0.02). The significant correlation was seen between Ki-67 and tumour grading (p=<0.0001). Patients with LVI (+) had higher Ki-67 expression (p=0.007). Luminal A tumours were correlated with low Ki-67 group (p=<0.0001). Ki-67 values had significant effect on DFS (p=0.03) but not OS (p=0.09). CONCLUSION: This study showed that high Ki-67 expression is associated with higher pT-stage, higher pN-stage, higher grade, ER/PR negativity, HER2/neu positivity, ECE and LVI positivity. The prognostic impact of Ki-67 was only demonstrated for DFS.

RESUMEN

Pseudolymphoma, also known as Jessner's lymphocytic infiltration, is a benign but usually chronic, T-cell infiltrating disease with erythematous papules and plaques usually seen on the skin of the face, neck, and back. The use of leech therapy also known as hirudotherapy has increased in recent years. Here, we report a 52-year-old male patient who had undergone hirudotherapy in his neck and developed infiltrating plaques after four months. A skin biopsy confirmed the diagnosis of Jessner's lymphocytic infiltration. In parallel with the increasing use of hirudotherapy in recent years, the side-effect reports will likely to increase. Indications and contraindications of hirudotherapy, which is being used officially in hospitals, should be taken into consideration.

RESUMEN

OBJECTIVE: Cervical cancer can be diagnosed early by cancer screening programs. The aim of this study was to evaluate the cervical smear test results of healthy women. METHODS: We enrolled 94,848 healthy women from 30-65 years of age in whom both HPV typing and a cervical smear test was performed between 2014 and 2017. RESULTS: HPV was detected in 3001 women (3.16%). The mean age was 42 ± 8.94 years old. Positive HPV types were HPV16; HPV16 and multiple infection; HPV31; HPV51; HPV39; HPV52; HPV56; HPV18; HPV68; HPV35; HPV18 and multiple infection; HPV58; HPV45; HPV59; HPV16, HPV18 and multiple infection; HPV16 and 18; and HPV33, in descending order. Cytology results were normal in 63.61%. We also identified atypical squamous cells of undetermined significance in 6.60%, atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion in 0.73%, low-grade squamous intraepithelial lesion in 10%, high-grade squamous intraepithelial lesion and atypical glandular cells in 0.53%, and adenocarcinoma in situ in 0.03%. In terms of HPV subtypes, abnormal smear results were divided into an HPV16, HPV18, and multiple infection group (25%), an HPV35 group (23.61%), an HPV 16 and multiple infection group (22%), and an HPV16-only group (21.85%). Most cases of HPV (39.02%) and abnormal cytology (43.04%) were detected between the ages of 30 and 40. CONCLUSIONS: This study is remarkable because it is a community-based study and includes a large population of healthy women to detect HPV prevalence, its subtype, and abnormal smear results.

RESUMEN

AIM: We determined the effects of diclofenac sodium, octreotide, and their combination on extrapancreatic organ injuries in caerulein-induced acute pancreatitis in mice. METHODS: A total of 58 BALB-C male mice (25 g) were divided into seven groups and used to create a caerulein-induced acute pancreatitis model. Diclofenac sodium, octreotide, and their combination were given for treatment of caerulin-induced acute pancreatitis in mice. At the end of the experiment, the lung, liver, kidney, and stomach were removed for histopathologic assessment. RESULTS: Histopathologic investigation revealed a statistically significant difference between the groups in mean congestion, edema, tubular injury, perirenal fat tissue inflammation, and tubular stasis scores in kidney tissue (P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.048, respectively); mean congestion, edema, neutrophil inflammation, mononuclear inflammation, and emphysematous change scores in the lung (P < 0.001, P < 0.001, P < 0.001, P = 0.030, and P < 0.001, respectively); mean congestion, edema, and neutrophil inflammation scores in the stomach (P = 0.008, P = 0.014, and P < 0.001, respectively); and mean congestion and hydropic degeneration scores in the liver (P = 0.029 and P = 0.002, respectively). CONCLUSION: Diclofenac sodium alone ameliorates lung edema due to caerulin-induced acute pancreatitis.
