Abstract
BACKGROUND The loss of skeletal muscle is a prognostic factor in several diseases including in patients with chronic limb threatening ischemia (CLTI). Patients with CLTI also have a lower skeletal mass and area when compared to those with claudication. However, there are no currently available data regarding the histological characteristics of core muscles in patients with CLTI. This study aims to determine the differences in core skeletal muscles between patients with claudication and those with CLTI. The second aim is to evaluate the differences in myokines, which are molecules secreted by skeletal muscle, between patients with claudication and those with CLTI. METHODS An observational, prospective study was conducted from January 2018 to July 2022 involving consecutive patients with peripheral arterial disease (PAD). The clinical characteristics were registered. In PAD patients with surgical indication for common femoral artery approach, samples of sartorius skeletal muscle (and not from the limb muscles directly involved in the ischemic process) were collected. The samples were submitted to histological characterization on hematoxylin-eosin and to immunohistochemical analysis to detect CD45+ leukocytes and CD163+ macrophages. The extent of the inflammatory cells (leukocytes and macrophages) was semiquantitatively assessed using a 0-to-4 grade scale as follows: absent (0†), mild (†), moderate (††), severe (†††), and very severe (††††). Serum levels of myokines: irisin, myostatin, IL-8, and lL-6 were determined with multiplex bead-based immunoassay. RESULTS 119 patients (mean age: 67.58 ± 9.60 years old, 79.80% males) 64 with claudication and 54 with CLTI were enrolled in the study. No differences were registered between patients with claudication and those with CLTI on age, gender, cardiovascular risk factors, and medication, except on smoking habits. There was a significantly higher prevalence of smokers and a higher smoking load in the claudication group. Samples of sartorius skeletal muscle from 40 patients (14 with claudication and 26 with CLTI) were submitted to histological analysis. No differences were found in skeletal muscle fibers preservation, trauma, or hemorrhage (on hematoxylin-eosin staining). However, in the immunohistochemistry study, we found more inflammatory cells CD45+ leukocytes in patients with CLTI when compared to those with claudication [CD45+ ≥ moderate (††): claudication (n = 14): 4; 28.57%; CLTI (n = 25): 16; 64.00%; P = 0.034]. Patients with CLTI also had higher tissue levels of CD163+ macrophages, but this difference was not significant [CD163+ ≥ moderate (††): claudication (n = 13): 7; 53.85%; CLTI (n = 27): 21; 77.78%; P = 0.122]. The serum levels of the myokines, irisin, and myostatin were below the lower limit of detection, in the majority of patients, so no valid results were obtained. However, patients with CLTI had a higher serum level of Interleukin (IL)-6 and IL-8. CONCLUSIONS CLTI patients exhibit increased quantities of leukocytes in their sartorius muscle, as well as elevated serum levels of myokines IL-8 and IL-6. Inflamed skeletal muscle can contribute to the loss of muscle mass and account for the lower density of skeletal muscle observed in CLTI. Additionally, inflamed skeletal muscle may contribute to the development of systemic inflammation through the secretion of pro-inflammatory cytokines into the systemic circulation. Halting the inflammatory process could eventually improve the prognosis of CLTI patients.

Abstract
PURPOSE To evaluate the effects of concentrated growth factor (CGF), combined with a mixture of iliac cancellous and composite bone materials, on the repair of extensive mandibular defects. PATIENTS AND METHODS This clinical trial involved patients with mandibular defects caused by large cystic lesions. The test group comprised 16 patients who underwent CGF combined with iliac cancellous bone and composite bone materials to repair extensive mandibular defects, whereas the control group comprised eight patients who underwent vascularised free fibula grafts for mandibular segmental defects. Postoperative exudatum was collected from patients on the 1st, 2nd, 3rd, and 4th days postoperatively, and osteogenic factor, including alkaline phosphatase (ALP), osteocalcin (BGP), and procollagen type I N-terminal propeptide (PINP), and inflammatory cytokines were performed. Additionally, regular cone beam computed tomography (CBCT) scans were conducted before and after surgery. RESULTS On postoperative days 1-4, the expression levels of ALP, BGP, and PINP were higher in the test group, while those of IL-1α, IL-1β, IL-6, IL-8, and TNF-α, which were identified as co-differentially expressing inflammatory cytokines, were all down-regulated in the exudatum of the test group. Regular CBCT radiological scans revealed a significant osteogenic effect in the test group. CONCLUSION The use of CGF combined with iliac cancellous bone and composite bone materials to repair extensive mandibular jaw defects facilitates bone formation and reductions in inflammation in the defect area in the short term, which deserves further research in clinical practice.

Abstract
We assessed the effects of anti-inflammatory treatment after selective laser trabeculoplasty through a systematic search of the MEDLINE, COCHRANE, and ClinicalTrials.gov. The outcome measures were intraocular pressure, anterior chamber inflammation, and discomfort. Evidence synthesis was performed using fixed effects or random-effects model according to the heterogeneity of the included studies. Heterogeneity was assessed using Q-statistic and I2. For an overall estimate of continuous outcomes, the mean differences and their 95% confidence intervals were applied, while odds ratios and their 95% confidence intervals were applied for dichotomous outcomes. Six studies were included in all. No significant difference was noted in the patients for intraocular pressure and discomfort when treated with anti-inflammatory drops. However, the patients showed benefit from reduced anterior chamber inflammation in the first postoperative week [FE OR=0.43, 95% CI=(0.19, 0.95), PQ=0.97, I2=0%], with no significant difference between the outcomes of non-steroidal anti-inflammatory drugs and steroids [FE OR=0.75, 95% CI=(0.20, 2.82), PQ=0.37, I2=0%]. Anti-inflammatory drops reduce anterior chamber inflammation after selective laser trabeculoplasty but showed no effect on the intraocular pressure.

Abstract
An 11-year-old girl presented with recurrent right lower quadrant (RLQ) pain. There was no evidence of inflammation and appendiceal swelling except at the initial onset. The repeated presence of a small amount of ascites at the time of abdominal pain triggered the performance of exploratory laparoscopy. Intraoperative examination revealed a non-inflamed, unswollen appendix with a cord-like atretic segment at the middle part and an appendectomy was performed. At 46 months follow-up, she remained asymptomatic. In patients with recurrent RLQ pain of unknown cause, it is necessary to consider diagnostic laparoscopy while keeping appendiceal atresia in mind as a differential diagnosis.

Abstract
Peri-implantitis is an inflammatory condition that involves the loss of attachment and support around dental implants. In this case report, a middle-aged woman presented with two implants in the mandibular right quadrant that were diagnosed with peri-implantitis. The patient also had tenderness around the implants and reported sensitivity when performing oral hygiene procedures. Surgical treatment comprised a free gingival graft to augment the keratinized tissue width around the implants, followed by a second procedure of implantoplasty and surface decontamination. The outcome showed radiographic resolution of the peri-implant defect around the premolar implant with a marked increase of keratinized tissue (> 4 mm) around both implants after 1 year of follow up. On a patient level, significantly reduced sensitivity around the implants and better home care were reported. This case report showed that the increase of keratinized tissue may benefit the clinical and patient outcomes of peri-implantitis treatment in terms of decreased probing depths, absence of inflammation, and improved radiographic crestal stability. The combined correction of both hard and soft tissue defects around peri-implantitis lesions may facilitate treatment success and help maintain peri-implant stability.

Abstract
OBJECTIVE The aim: To increase the efficiency of surgical treatment of patients with chronic lung abscesses by developing mini-invasive methods of surgical treatment using electrosurgical technologies. PATIENTS AND METHODS Materials and methods: Conducted study of the results of surgical treatment of 78 patients with chronic lung abscesses operated from 2011 to 2021. Patients were divided into two groups: the main group (37 patients who were treated using developed technologies) and a comparison group (41 patients, treated using traditional tactics). RESULTS Results: Transthoracic and endobronchial sanitation of the purulent cavity in the lung at the first stage of treatment contributed to the rapid elimination of inflammation and significantly accelerated the regeneration of lung tissue. Clinical effectiveness in the main group was expressed in reducing the phenomena of intoxication, decrease in Leukocyte intoxication index (LII) (early as on day 5 after surgery), on the 10th day, a significant reduction in patients bacterial excretion was noted (in the main group by 18.9%, in the comparison group - by 14.6%), the average time of reducing the abscess cavity by 1/4 of the volume 6 days less, the healing time of the cavity of the AL which is on average 13 and 16 days, respectively, less. CONCLUSION Conclusions: The developed methods of surgical interventions made it possible to significantly positively influence the level of endogenous intoxication indicators, avoid resection surgical interventions, reduce the number of postoperative complications, avoid damage to neighboring organs, reduce the time of patients with achieving a stable positive effect.

Abstract
BACKGROUND To investigate the clinical effects of intubation and sphincterotomy with wire-guided incision knife plus balloon dilatation (ISBD) in the treatment of choledocholithiasis, a randomized controlled trial was conducted. METHODS A total of 270 patients with choledocholithiasis confirmed by computed tomography or magnetic resonance imaging from January 2016 to July 2018 in our hospital were enrolled in the research. All patients were randomly divided into 3 groups: ISBD group, endoscopic sphincterotomy (EST) group, and endoscopic sphincterotomy plus balloon dilation group, respectively. The clinical effects, complications, and inflammation indexes of the 3 groups were detected. SPSS software was used for statistics and analysis of results. RESULTS There were no significant differences in basic characteristics of the 3 groups. Although there was no significant difference in the total stone clearance rate among the 3 groups, the first stone clearance rate and the large stone clearance rate in ISBD group were significantly higher than those in EST group. Compared with the other 2 groups, the total operation time and complications in ISBD group were significant lower. The serum levels of interleukin-6, C-reactive protein (CRP), procalcitonin (PCT), carbohydrate antigen 19-9, and carcinoembryonic antigen in ISBD group were significant lower than those in EST group, and CRP and PCT in ISBD group were markedly lower than those in endoscopic sphincterotomy plus balloon dilation group. CONCLUSIONS ISBD treatment simplifies the operation procedure, shortens the operation time, reduces postoperative inflammation and complications, and makes ERCP stone removal simpler, safer, and more efficient for patients with common bile duct stones.

Abstract
PURPOSE To report two cases of idiopathic intraocular cilia presenting as sectoral scleritis with progressive intraocular inflammation. METHODS Both patients were treated with intravitreal antibiotics and underwent pars plana vitrectomy where the cilia were removed and identified on histopathology. RESULTS One patient developed a retinal detachment while being treated for presumed endophthalmitis. The intraocular cilium was discovered during pars plana vitrectomy. In the second case, the cilium was detected on dilated fundus exam and was believed to be the cause of the patient's scleritis and vitritis. Therapeutic vitrectomy was performed. In both cases, the cilia were positively identified on histopathology. CONCLUSION Idiopathic intraocular penetration of cilia should be considered in the differential diagnosis of sectoral scleritis with progressive intraocular inflammation.

Abstract
We here report a case of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia treated by radical resection. A 71-year-old man presented to our hospital because of abdominal bloating. Diagnoses of early-stage pancreatic body cancer with pancreatic duct rupture, pancreatic ascites, and formation of a pseudocyst were made on the basis of blood tests, multidetector dynamic computed tomography, endoscopic ultrasonography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography. After achieving control of the ascites by placement of a pancreatic duct stent and aspiration of the pseudocyst, distal pancreatectomy with D2 lymph node dissection was performed. Intraoperative cytologic examination of the ascites was negative. The pathological diagnosis was high-grade pancreatic intraepithelial neoplasia in the pancreatic body. The branched pancreatic duct was occluded and dilated by acute inflammation around the pancreatic neoplasm, the inflammation being in the region of the dilated branched pancreatic duct and having caused its rupture. To the best of our knowledge, this is the first published report of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia.

Abstract
BACKGROUND Many conditions, among them vestibular schwannoma and middle ear cholesteatoma with lateral semicircular canal destruction, may be associated with asymmetrical sensorineural hearing loss (SNHL) and vertigo. However, the probability that these two distinct disease entities causing the same symptoms occur in a single patient is very low, approximately 1 per 28 billion per 1 year. METHODS We present the case of a 40-year-old male admitted to our clinic because of chronic middle ear inflammation with concomitant tinnitus vertigo, and deafness in the right ear. The patient was diagnosed with lateral semicircular canal fistula caused by middle-ear cholesteatoma and concomitant vestibular schwannoma. Canal wall-down surgery was carried out to remove the cholesteatoma, followed by gamma knife radiosurgery for the vestibular schwannoma. RESULTS Vertigo and tinnitus resolved within 3 days after the ear surgery, and gamma knife treatment resulted in the complete involution of the vestibular schwannoma. The patient presented with completely dry middle-ear cavity and no recurrence of the cholesteatoma was observed during a 3-year follow-up. CONCLUSION As the hereby reported condition is very rare, the results cannot be compared with any similar report published previously. Nevertheless, based on the outcome, the treatment strategy seems to be both reasonable and effective.

Abstract
One of the main obstacles to studying the pathophysiology of lymphedema development is the lack of appropriate experimental models. Fol-lowing up on a mouse-tail method that has been described, we performed changes to the method which made it easier to perform in our hands and demonstrated similar results. Twenty C57Black mice were operated on using the previous tech-nique and euthanized after 3 or 6 weeks. Another twenty mice were submitted to the new technique developed in our laboratory and euthanized at the same time points. Tissue samples were collected from the proximal part of the tail (control) and from the distal part (lymphedema) for both mod-els. Animals in both operative groups developed marked edema in the distal part of the tail. This was characterized by lymph vessels dilation, edema, inflammatory cell infiltration, and adipose tissue deposition. Lymphedema was detected after 3 weeks in both models, reaching its maximum after 6 weeks. Adipocytes detected by histology (Oil red O staining) and molecular markers for adipogenesis, lymphangiogenesis and inflam-mation (lipin 1 and 2, SLP76, and F4-80) were demonstrated to be increased equally in both models. In conclusion, both models provide a reliable method to study lymphedema pathophys-iology. However, our modified technique is easier and faster to perform while still providing reliable and consistent results.

Abstract
BACKGROUND & AIMS Hepatic alterations, such as in non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are frequently associated with obesity. To investigate the molecular mechanisms of these alterations and to identify molecules that could be used as potential therapeutic targets, we investigated the modulation of hepatic indices of oxidative stress and inflammation in obese patients undergoing laparoscopic sleeve gastrectomy (LSG). METHODS Patients (n = 436) attending our obesity clinic underwent LSG for weight loss. We obtained a diagnostic intraoperative liver biopsy, and a sub-cohort (n = 120) agreed to a 1-year follow-up that included donation of blood samples and additional liver biopsies. Selected key molecules in blood and liver tissue were used to investigate the hepatic alterations in obesity, and their response to LSG. RESULTS One year post-surgery, the prevalence of diabetes, dyslipidemia and hypertension decreased significantly. LSG improved liver histology features in all patients. Improvement was greater in severe cases of NAFLD including those with steatohepatitis, bridging fibrosis or cirrhosis. Significant pre-surgery differences in plasma, and liver markers of oxidative stress and inflammation (including chemokine C-C motif ligand 2, paraoxonase-1, galectin-3, and sonic hedgehog) were observed between patients with, and those without, NASH; post-surgery indicated consistent improvements in these parameters. CONCLUSION Our study shows that the histology and liver function of patients with morbid obesity are significantly improved after LSG via mechanisms that involve the reduction of oxidative stress and inflammatory processes. These data encourage the use of LSG as a therapeutic option to improve, or resolve, NAFLD.

Abstract
PURPOSE To investigate the correlations of recurrence after radical surgery for esophageal cancer with glucose-lipid metabolism, insulin resistance, inflammation, stress and serum p53 expression. METHODS A total of 80 patients with esophageal cancer treated in our hospital from February 2015 to October 2017 were selected and divided into two groups with 40 cases in each group. All patients enrolled underwent open radical surgery for esophageal cancer, combined with chemoradiotherapy and biotherapy after surgery, and all of them were followed up for 1 year. Postoperative recurrence, glucose-lipid metabolism, insulin resistance and inflammatory and stress responses were compared. Additionally, the serum p53 antibody index was recorded. Moreover, the relevant and independent risk factors and the correlations of postoperative recurrence time of esophageal cancer were analyzed. RESULTS At 1-year follow-up after surgery, the levels of glucose-lipid metabolism indices, inflammatory factors and stress response in recurrence group were significantly higher than those in non-recurrence group (p<0.05), while the insulin resistance, the superoxide dismutase level and total antioxidant capacity in recurrence group were significantly greater than that in non-recurrence group (p<0.05). Besides, at 6-month and 1-year follow-up, the serum P53 antibody index in recurrence group was obviously higher than that in non-recurrence group (p<0.05). The complicated hypertension, hyperlipidemia and diabetes mellitus were relevant and independent risk factors for the postoperative recurrence of esophageal cancer (p<0.05). The postoperative recurrence time of esophageal cancer was negatively correlated with the levels of fasting blood glucose, total cholesterol, insulin resistance, high-sensitivity C-reactive protein and serum P53 antibody index (p<0.05), while it was positively correlated with the superoxide dismutase level (p<0.05). CONCLUSIONS The complicated hypertension, hyperlipidemia and diabetes mellitus are relevant and independent risk factors for the postoperative recurrence of esophageal cancer. The earlier postoperative recurrence time corresponds to the higher levels of fasting blood glucose, insulin resistance index and total cholesterol, and the stronger inflammatory and oxidative stress responses. At the same time, the changes in the p53 level have a certain guidance value in predicting the postoperative recurrence.

Abstract
PURPOSE To explore the influence of postoperative enteral nutrition combined with adjuvant radiotherapy on inflammatory response, nutrition, healing and prognosis in patients undergoing radical surgery for esophageal carcinoma. METHODS A total of 114 patients with esophageal carcinoma receiving radical surgery from January 2016 to July 2017 composed the observation group and randomly divided into control group (n=57) and study group (n=57). Patients in the control group were given routine nutritional support after surgery, while those in the study group received enteral nutrition after surgery. The changes in inflammatory response and nutritional level, healing and prognosis in the two groups of patients before and after treatment were compared and analyzed. RESULTS After treatment, the levels of serum hypersensitive C-reactive protein (hs-CRP) and prostaglandin E (PGE) of patients were decreased in both the control group and study group, and they were lower in the study group than those in the control group, while the levels of serum pro-albumin (PA) and albumin (ALB) of patients in the study group were higher than those in the control group (p<0.05). The postoperative wound healing time, total length of hospital stay, postoperative first exhaust time and defecation time in the study group were shorter than those in the control group (p<0.05). The total incidence rate of postoperative complications of patients in the study group was lower than that in the control group (p<0.05). CONCLUSION The application of postoperative enteral nutrition combined with adjuvant radiotherapy in patients subjected to radical surgery for esophageal carcinoma can suppress systemic inflammatory response, improve the nutritional condition, promote postoperative wound healing and improve prognosis and therefore it is worthy of promotion in clinical practice.

Abstract
Introduction Appendicitis is one of the most common causes of acute abdomen. The clinical presentation of appendicitis and its susceptibility to acute inflammation may be affected by the length and position of vermiform appendix. Length and position of appendix are variable. The aim of the study was to find the prevalence of retrocaecal appendix among patients undergoing appendectomy for appendicitis. Methods A descriptive cross-sectional study was performed in 264 patients undergoing appendectomy in Department of Surgery, Nobel Medical College, Biratnagar, Nepal from 1st May, 2018 to 15th May, 2019. Ethical approval was taken. Simple random sampling was done. The position of appendix was noted before appendectomy. Subgroup analysis was done on the basis of gender and length of appendix recorded in centimeters with a measuring scale immediately after removal of appendix. Data was collected in excel and was analyzed in SPSS version 16. Results Prevalence of retrocaecal appendix among patients with appendicitis was 95 (35.98%). Similarly, other positions noted were pelvic in 67 (25.37%), post-ileal in 61 (23.10%), pre-ileal in 11 (4.16%) and subcaecal in 30 (11.36%) individuals. The length of appendix ranged from 1.7 cm to 14.7 cm. The mean length was 8.67±2.44 cm. Conclusions The most common position of appendix in patients with appendicitis is retrocaecal position followed by pelvic position in both males and females.

Abstract
PURPOSE Retinal detachment (RD) is one of the most frequently diagnosed ophthalmologic conditions requiring prompt surgical intervention. Combination of proper surgical technique and new diagnostic markers, both clinical and molecular, can help improve the diagnosis and prognosis of RD treatment. METHODS 12 patients with rhegmatogenous RD (rRD) were included into the study after obtaining patient consent and Regional Ethical Approval (average age: 58.1 ± 17.4 years). OCT was performed before and after 23G vitrectomy for RD. Pure subretinal fluid (SRF) was collected during surgery and analyzed by protein array profiling on a panel of 105 inflammatory cytokines (Human XL Cytokine Array), while the effect of SRF upon human macrophages-driven phagocytosis of apoptotic retinal pigment epithelial (RPE) cells ex vivo was quantified by flow cytometry. Immunohistochemistry (IHC) of retinectomized tissue due to PVR caused by RD was performed to determine presence of markers for microglial cells (CD34), macrophages and activated microglia (CD68), regulator of the immune response to infection (NFkB), progenitor and stem cell marker (Sox2), pluripotency marker (Oct4) and intermediate filament markers (GFAP and Nestin). RESULTS OCT of fresh RD patients contained pre-operatively hyper reflective points (HRPs) at the detached neuroretina border and proximal to the RPE layer-their size and number decreased following successful reattachment surgery. IHC of the retinectomized tissue from detached retina due to severe PVR showed presence of cell conglomerates at the detached neuroretina border which were positive for CD68, NFkB, Sox2 and GFAP, less positive for CD47 and Nestin and negative for Oct4 and CD34. The SRF contained at least 37 cytokines with higher, and 4 cytokine with lower concentration compared to that in vitreous from non-RD pathology; when used as conditional medium to human macrophages ex vivo, the SRF doubled their capacity for engulfing dying RPEs. CONCLUSIONS Fresh RD can be hallmarked by presence of HRPs at the detached neuroretina border on OCT; the HRPs decrease in size and number after successful reattachment surgery, and likely resemble the macrophage conglomerates seen by IHC. The neuroretina in RD contains progenitor/stem-like cells and signs of inflammatory reaction, while the SRF contains inflammatory cytokines and other factors which increase the ability of professional phagocytes to engulf dying RPE, or for that matter, other dying cells in the retina.

Abstract
AIM To present treatment strategy for large volumes of injectable non-absorbable 'shell-less' soft tissue fillers (vaseline, synthol, silicone etc.). MATERIAL AND METHODS The authors present an experience of surgical treatment of 8 patients who underwent injections of medical vaseline (breast augmentation, n=5) and synthol (muscles enlargement, n=3) and review of the current literature devoted to this problem. RESULTS Injection of large amounts (over 50 ml) of non-absorbable fillers into soft tissues is unacceptable and leads to numerous complications. Oil-based 'shell-less' fillers cannot be removed by minimally invasive techniques (puncture, mini-incisions, etc.) due to multiple diffuse lesions in the form of oleogranulomas (cysts of different size) and surrounding widespread inflammation and fibrosis of tissues. Surgery is the only adequate method. However, this approach is followed by scars and often tissue contour deformation. Migration of these fillers to other anatomical areas (from the neck to the lower extremities) significantly complicates the situation, treatment and results. In case of categorical refusal of patients from surgical treatment and no complaints, they should be properly informed about possible consequences and complications and dynamic medical supervision is necessary. Intraoperative ultrasound examination is useful for the control of radical removal of pathological areas. Timely removal of non-absorbable fillers allows to avoid serious complications and to achieve good aesthetic results.

Abstract
Tears are a constantly available and highly valuable body fluid collectable by non-invasive techniques. Although it can give information on ocular status and be used for follow-ups, tear analysis is challenging due to the low amount of sample that is available. Proximity extension assay (PEA) allows for a sensitive and scalable analysis of multiple proteins in a single run from a one-µL sample, so we applied this technique and examined the amount of 184 proteins in tears collected at different time points after trabeculectomy. The success rate of this surgical intervention highly depends on proper wound healing; therefore, information on the process is indispensable. We observed significantly higher levels of IL-6 and MMP1 at the early time points (day one, two, and four) following trabeculectomy, and the protein amounts went back to the level observed before the surgery three months after the intervention. Patients with or without complications were tested, and proteins that have roles in the immune response and wound healing could be observed with altered frequency and amounts in the cases of patients with complications. Our results highlight the importance of inflammation in wound-healing complications, and at the same time, indicate the utility of PEA in tear analysis.

Abstract
OBJECTIVE Adenotonsillectomy (AT) is one of the most common surgical procedures performed in children and adults. We aim to assess the factors associated with changes in the incidence of and indications for AT using population-level data. STUDY DESIGN This retrospective cohort study investigated patients who underwent AT between 1997 and 2010 by using data from the Taiwan National Health Insurance Research Database. We examined surgical rates and indications by the calendar year as well as age, sex, hospital level, and insured residence areas for the correlating factors. RESULTS The average annual incidence rate of AT was 14.7 per 100,000 individuals during 1997-2010. Pediatric (<18 years) patients represented 48.2% of the total AT population. More than 99% of the patients underwent the AT procedures as an inpatient intervention. Longitudinal data demonstrated an increasing trend in the pediatric AT rates from 1997 (4.3/100,000) to 2010 (5.7/100,000) (p = 0.029). In the adult subgroup, a decreasing prevalence of infectious indications (p = 0.014) coincided with an increasing neoplastic indications (p = 0.001). In the pediatric subgroup, the prevalence of obstructive indications increased (p = 0.002). The logistic regression analyses indicated that the significant factors associated with the changing surgical indications for AT were the age in the adult subgroup and hospital level in the pediatric subgroup. CONCLUSIONS This study revealed a low AT rate in Taiwan than that in other countries. Pediatric AT incidence increased during 1997-2010. Although a rising prevalence of obstructive and neoplastic indications was noted, infection remained the most common indications for AT. Age in the adult subgroup and hospital level in the pediatric subgroup were factors associated with the changing indications for AT.

Abstract
BACKGROUND Prostate cancer is the most commonly diagnosed cancer in north-American men. Few dietary or lifestyle interventions have been tested to prevent prostate cancer progression. Omega-3 fatty acid supplementation represents a promising intervention for prostate cancer patients. The aim of the study is to evaluate the effects of long-chain omega-3 polyunsaturated fatty acids (LCn3), more precisely eicosapentaenoic acid monoacylglyceride (MAG-EPA) supplementation, on prostate cancer proliferation, inflammation mediators and quality of life among men who will undergo radical prostatectomy. METHODS/DESIGN We propose a phase IIb, randomized, double-blind placebo-controlled trial of MAG-EPA supplementation for 130 men who will undergo radical prostatectomy as treatment for a prostate cancer of Gleason score ≥ 7 in an academic cancer center in Quebec City. Participants will be randomized to 6 capsules of 625 mg of fish oil (MAG-EPA) per capsule containing 500 mg of EPA daily or to identically looking capsules of high oleic acid sunflower oil (HOSO) as placebo. The intervention begins 4 to 10 weeks prior to radical prostatectomy (baseline) and continues for one year after surgery. The primary endpoint is the proliferative index (Ki-67) measured in prostate cancer cells at radical prostatectomy. A secondary endpoint includes prostate tissue levels of inflammatory mediators (cytokines and proteins) at time of radical prostatectomy. Changes in blood levels of inflammatory mediators, relative to baseline levels, at time of radical prostatectomy and 12 months after radical prostatectomy will also be evaluated. Secondary endpoints also include important aspects of psychosocial functioning and quality of life such as depression, anxiety, sleep disturbances, fatigue, cognitive complaints and prostate cancer-specific quality of life domains. The changes in these outcomes, relative to baseline levels, will be evaluated at 3, 6, 9 and 12 months after radical prostatectomy. DISCUSSION The results from this trial will provide crucial information to clarify the role of omega-3 supplementation on prostate cancer proliferation, inflammation and quality of life.

Abstract
OBJECTIVE Introduction: Implementation of the endoscopic technologies while the upper airways diseases gave opportunity to diagnose the adenoid vegetation in adults. The aim: Тo offer effective algorithm of curing adults for adenoiditis, depending on the degree of pharyngeal tonsil hypertrophy. PATIENTS AND METHODS Materials and methods: 43 patients aged 18 - 55 with hypertrophy of pharyngeal tonsil were examined. Depending on the degree of hypertrophy three clinical groups of patients was created: the first one receiving only conservative treatment, the second one receiving conservative therapy and radiowaveradiation coagulation with the apparatus "SURGITRON" and the third one receiving the endoscopic shave adenotomy. Statistical processing of the received data was made in the programs «Exсel» and «STATISTICA 6.0». Data rows were checked for the normality with the help of Shapiro-Wilk statistical criteria (small sample) and Kolmohorov-Smirnov (large sample). Checking of the dispersion uniformity was done by Leneva criteria. During the comparison of the rows criteria of Student and Wilkokson for the non-paired, Kolmogorov-Smirnov were used. RESULTS Results: During the re-examination of patients who received only conservative therapy treatment in a month endoscopic signs adenoiditis were distinguished and a year later percentage of relapse was higher than in patients with complex treatment. After shave adenotomy adenoiditis recurrence was not observed. CONCLUSION Conclusions: While treatment of the patients with the pharyngeal tonsil hypertrophy of the 1 and 2 degree conservative therapy is possible. Addition into the scheme of conservative treatment RWCAV actually reduces quantity of adenoiditis recurrence and allows fast recovery. Treatment of patients with the pharyngeal tonsil hypertrophy of 3 degree, in context of contraindication absence requires surgical treatment (adenotomy) in 100% of cases.

Abstract
PURPOSE The distinction between active inflammation and fibrosis of the bowel wall is essential for therapeutic decisions in stricturing Crohn's disease. We aimed to assess whether real-time elastography (RTE) with strain ratio measurement could be useful in differentiating fibrotic from inflamed bowel strictures and to evaluate the possible relationship between US techniques and the histology of the stenotic bowel wall. MATERIALS AND METHODS Bowel ultrasonography (including RTE, color-Doppler and CEUS examination) was prospectively evaluated in 26 patients with symptomatic stricturing Crohn's disease, before surgery. RTE was adopted to evaluate bowel stiffness: five loops of 20 RTE frames were recorded for each stenotic segment and the mean strain ratio (MSR) was obtained. Histology scoring systems both for inflammation and fibrosis were established for surgical specimens. RESULTS No significant correlation was found between MSR and fibrosis score (P = 0.877). Color-Doppler score was significantly related to gut wall and submucosal thicknesses (P = 0.006 and P = 0.032, respectively). There was no significant correlation between the number of vessels counted at histology and color-Doppler and CEUS examinations (P = 0.170 and P = 0.302, respectively). CONCLUSION MSR detection was not able to distinguish fibrotic from inflammatory tissue in our selected population. This result could be influenced by the presence of the superimposed inflammation. Larger cohort of patients, further analysis with shear wave elastography, and validated histopathology classification systems for fibrosis and inflammation are necessary to assess if intestinal fibrosis could be reliably detected on the basis of bowel elastic properties.

Abstract
A 63-year-old man presented with abdominal pain in the lower right quadrant and high fever. An abdominal CT scan on admission revealed ileocecal wall thickening and inflammation of the terminal ileum. No foreign body was observed on CT scan. He received antibiotic therapy, but no improvement was noticed. Colonoscopy showed a sporadic type 0- I s+ II c lesion in the sigmoid colon. Histological examination showed well differentiated adenocarcinoma. We diagnosed the patient as having inflammation of the terminal ileum and sigmoid colon cancer. Laparoscopic surgery was performed. Inflammation was present in the terminal ileum, and local resection and sigmoidectomy were performed. A foreign body that appeared to be a fish bone was present in the resected specimen, and this led to the diagnosis of granulomatous inflammation of the ileum caused by fish bone. In the sigmoid colon, the pathological diagnosis was pT1b(sm), pN0, ly1, v1, pDM0, pPM0, R0, pStage I . He was discharged without any complication and has not shown any evidence of recurrence more than 1 year after surgery.

Abstract
BACKGROUND Treatment response in lupus nephritis (LN) is defined clinically, without consideration of renal histology. Few studies have systematically examined histologic responses to induction therapy. In LN patients who underwent protocol kidney biopsies after induction immunosuppression, we describe the renal histology of the second biopsy and correlate histologic activity and damage with short- and long-term kidney outcomes. METHODS Patients with suspected LN were biopsied for diagnosis (Biopsy 1), and those with proliferative LN were rebiopsied after induction (Biopsy 2). Histologic activity and damage at each biopsy were calculated as the National Institutes of Health activity and chronicity indices. Complete and partial renal responses after induction and after long-term follow-up were determined clinically. RESULTS One-third of patients who achieved a complete clinical response after induction had persistently high histologic activity, and 62% of patients who had complete histologic remission on rebiopsy were still clinically active. Chronic renal damage increased after induction even in complete clinical responders. Chronicity at Biopsy 2 associated with long-term kidney function and development of chronic kidney disease. CONCLUSIONS Early clinical and histologic outcomes are discordant in proliferative LN, and neither correlates with long-term renal outcome. The kidney accrues chronic damage rapidly and despite clinical response in LN. Preservation of kidney function may require therapeutic targeting of both chronic damage and inflammation during LN induction treatment.

Abstract
CONTEXT The mechanisms mediating the short- and long-term improvements in glucose homeostasis following bariatric/metabolic surgery remain incompletely understood. OBJECTIVE To investigate whether a reduction in adipose tissue inflammation plays a role in the metabolic improvements seen after bariatric/metabolic surgery, both in the short-term and longer-term. DESIGN Fasting blood and subcutaneous abdominal adipose tissue were obtained before (n=14), at one month (n=9), and 6-12months (n=14) after bariatric/metabolic surgery from individuals with obesity who were not on insulin or anti-diabetes medication. Adipose tissue inflammation was assessed by a combination of whole-tissue gene expression and flow cytometry-based quantification of tissue leukocytes. RESULTS One month after surgery, body weight was reduced by 13.5±4.4kg (p<0.001), with improvements in glucose tolerance reflected by a decrease in area-under-the-curve (AUC) glucose in 3-h oral glucose tolerance tests (-105±98mmol/L * min; p=0.009) and enhanced pancreatic β-cell function (insulinogenic index: +0.8±0.9pmol/mmol; p=0.032), but no change in estimated insulin sensitivity (Matsuda insulin sensitivity index [ISI]; p=0.720). Furthermore, although biomarkers of systemic inflammation and pro-inflammatory gene expression in adipose tissue remained unchanged, the number of neutrophils increased in adipose tissue 15-20 fold (p<0.001), with less substantial increases in other leukocyte populations. By the 6-12month follow-up visit, body weight was reduced by 34.8±10.8kg (p<0.001) relative to baseline, and glucose tolerance was further improved (AUC glucose -276±229; p<0.001) along with estimated insulin sensitivity (Matsuda ISI: +4.6±3.2; p<0.001). In addition, improvements in systemic inflammation were reflected by reductions in circulating C-reactive protein (CRP; -2.0±5.3mg/dL; p=0.002), and increased serum adiponectin (+1358±1406pg/mL; p=0.003). However, leukocyte infiltration of adipose tissue remained elevated relative to baseline, with pro-inflammatory cytokine mRNA expression unchanged, while adiponectin mRNA expression trended downward (p=0.069). CONCLUSION Both the short- and longer-term metabolic improvements following bariatric/metabolic surgery occur without significant reductions in measures of adipose tissue inflammation, as assessed by measuring the expression of genes encoding key mediators of inflammation and by flow cytometric immunophenotyping and quantification of adipose tissue leukocytes.

Abstract
BACKGROUND Inflammation and tumor are now an inseparable binomial. Inflammation may also derive by the use of breast implants followed by the formation of a periprosthetic capsule. It is known that tumor cells, in an inflamed microenvironment, can profit by the paracrine effect exerted also by mesenchymal stem cells (MSCs). Here we evaluated the role of inflammation on the immunobiology of MSCs before and after cocultures with cells derived from breast adenocarcinoma. METHODS MSCs derived from both inflamed (I-MSCs) and control (C-MSCs) tissues were isolated and cocultured with MCF7 cells derived from breast adenocarcinoma. Before and after cocultures, the proliferation rate of MCF7 cells and the expression/secretion of cytokines related to inflammation were tested. RESULTS Before cocultures, higher levels of cytokine related to chronic inflammation were detected in I-MSCs than in C-MSCs. After cocultures with MCF7, C- and I-MSCs show a variation in cytokine production. In detail, IL-2, IL-4, IL-5, IL-10, IL-13, TGF-β and G-CSF were decreased, whereas IL-6, IL-12, IFN-γ, and IL-17 were oversecreted. Proliferation of MCF7 was significantly increased after cocultures with I-MSCs. CONCLUSIONS Inflammation at the site of origin of MSCs affects their immunobiology. Even if tumor cells increased their proliferation rate after cocultures with I-MSCs, the analysis of the cytokines, known to play a role in the interference of tumor cells with the host immune system, absolves completely the breast implants from the insult to enforce the risk of adenocarcinoma.

Abstract
OBJECTIVE To explore the treatment of vesiculitis with hemospermia by transurethral seminal vesiculoscopy. METHODS We treated 64 cases of vesiculitis with hemospermia by transurethral seminal vesiculoscopy. During the operation,we removed the stones and inflammatory substances and collected seminal vesicle fluid to be cultured for bacteria,ureaplasma urealyticum(UU),chlamydia trachomatis(CT),and mycoplasma hominis(MH),followed by infusion of levofloxacin at 0. 3 g/100 ml into the seminal vesicle. Regular follow-up was conducted post-operatively. RESULTS All the operations were successfully accomplished, the operation time averaging(40 ± 15) min(25- 50 min). The ejaculatory duct opening was observed on the verumontanum surface in the posterior urethra in 2 cases, abnormal passages found in the prostatic utricle in 8 cases, and seminal vesicle fenestration from the prostatic utricle conducted in the other 54 cases(32 by seminal vesiculoscopy and 22 with holmium laser). Stones were seen in the prostatic utricle in 5 cases, in the seminal vesicle in 6 cases, and in both the prostatic utricle and seminal vesicle in 2 cases. Culture of the seminal vesicle fluid showed the acinetobacter to be positive in 1 case and UU, CT, and MH to be negative. At 3 months after surgery, hemospermia was cured in 52 cases, relieved in 8,and unimproved in 4. CONCLUSION Seminal vesicle fenestration drainage by transurethral seminal vesiculoscopy for the treatment of vesiculitis with hemospermia has the advantages of short operation time, high effectiveness and no obvious complications and can also be employed for the examination of the seminal vesicle as well as removal of stones and inflammatory substances.

Purpose To evaluate the short-term changes in ocular surface measures and tear inflammatory mediators after femtosecond lenticule extraction (FLEx) and small-incision lenticule extraction (SMILE) procedures. Methods Eighteen subjects (18 eyes) underwent FLEx and 23 subjects (23 eyes) underwent SMILE in this single-center and prospective study. Central corneal sensitivity, Schirmer I test (SIT), noninvasive tear breakup time (NI-TBUT), tear meniscus height, corneal fluorescein (FL) staining, and ocular surface disease index (OSDI) were assessed in all patients. Concentrations of interleukin-1α (IL-1α), tumor necrosis factor-α (TNF-α), nerve growth factor (NGF), interferon-γ (IFN-γ), transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase-9 (MMP-9) in collected tears were measured by multiplex antibody microarray. Results Central corneal sensitivity was reduced in both groups, but the scores in the SMILE group were higher than those in the FLEx group at all time points postoperatively (P<0.01). Lower FL scores and longer NI-BUT were observed in the SMILE group 1 week after surgery (P<0.05). OSDI scores in both groups increased rapidly at 1 day and 1 week postoperatively, then returned to their preoperative levels within 1 month (P<0.05). There were no significant differences in SIT or tear meniscus height between the two groups. Lower and faster recovery of tear NGF, TGF-β1 and IL-1α concentration were found in the SMILE group compared to the FLEx group postoperatively. No significant difference was found in tear TNF-α, IFN-γ and MMP-9 for either group before or after surgery. Tear NGF, TGF-β1 and IL-1α show a correlation with ocular surface changes after FLEx or SMILE surgery. Conclusion SMILE has superiority over FLEx in early ocular surface changes and NGF, TGF-β1 and IL-1α may contribute to the process of ocular surface recovery.

Abstract
This paper presents a case of a patient with invasive ductal breast cancer following breast augmentation. Following breast implants rupture in March 2013 the breast implants have been removed - histopathological examination revealed leaked silicone with inflammatory infiltration, without evidence of cancerous lesions. Diagnostic imaging revealed multiple encapsulated silicone particles and clusters of post-inflammatory macrocalcifications in both breasts. In January 2014 the patient presented with symptoms of massive inflammation of the left breast. Following surgical consultation the patient had undergone radical left-sided mastectomy with lymphadenectomy. Postoperative histopathological examination revealed a multifocal advanced invasive ductal cancer G3 pT3pN3a (vascular invasion, metastases in 11 of 12 examined axillary lymph nodes). Following surgery the patient was qualified for further treatment - chemotherapy, radiotherapy, hormone therapy. The discussion includes a review of literature on the risk evaluation of co-occurrence of breast cancers in women with silicone breast implants and presents diagnostic challenges of breast cancer in this patient group.

Abstract
Isolated bilateral abducens nerve palsy raises concern about a serious intracranial condition. Abducens nerve palsy is a common isolated palsy due to its susceptibility to injury along its long course. Non-traumatic isolated abducens nerve palsy is often caused by a mass that indirectly stretches and compresses the nerve. Pathological processes directly causing bilateral isolated involvement of the abducens nerve are rare. We describe a 24-year-old man who presented with isolated bilateral abducens nerve palsy. Radiological imaging and laboratory tests were consistent with an aggressive bacterial infectious process located in the sellar region with parasellar extension. If promptly addressed, sixth cranial nerve palsy appears to be reversible with aggressive medical therapy and endoscopic sinus surgery.

Abstract
BACKGROUND AIMS Modulation of inflammation after brain trauma is a key therapeutic goal aimed at limiting the consequences of the subsequent injury cascade. Mesenchymal stromal cells (MSCs) have been demonstrated to dynamically regulate the inflammatory environment in several tissue systems, including the central nervous system. There has been limited success, however, with the use of direct implantation of cells in the brain caused by low viability and engraftment at the injury site. To circumvent this, we encapsulated MSCs in alginate microspheres and evaluated the ability of these encapsulated MSCs to attenuate inflammation in rat organotypic hippocampal slice cultures (OHSC). METHODS OHSC were administered lipopolysaccharide to induce inflammation and immediately co-cultured with encapsulated or monolayer human MSCs. After 24 h, culture media was assayed for the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α) produced by OHSC, as well as MSC-produced trophic mediators. RESULTS Encapsulated MSCs reduced TNF-α more effectively than did monolayer MSCs. Additionally, there was a strong correlation between increased prostaglandin E2 (PGE2) and reduction of TNF-α. In contrast to monolayer MSCs, inflammatory signals were not required to stimulate PGE2 production by encapsulated MSCs. Further encapsulation-stimulated changes were revealed in a multiplex panel analyzing 27 MSC-produced cytokines and growth factors, from which additional mediators with strong correlations to TNF-α levels were identified. CONCLUSIONS These results suggest that alginate encapsulation of MSCs may not only provide an improved delivery vehicle for transplantation but may also enhance MSC therapeutic benefit for treating neuro-inflammation.

Abstract
Burn-induced neuropathic pain is complex, and fat grafting has reportedly improved neuropathic pain. However, the mechanism of fat grafting in improving neuropathic pain is unclear. Previous investigations have found that neuroinflammation causes neuropathic pain, and anti-inflammatory targeting may provide potential therapeutic opportunities in neuropathic pain. We hypothesized that fat grafting in burn scars improves the neuropathic pain through anti-inflammation. Burn-induced scar pain was confirmed using a mechanical response test 4 weeks after burn injuries, and autologous fat grafting in the scar area was performed simultaneously. After 4 weeks, the animals were sacrificed, and specimens were collected for the inflammation test, including COX-2, iNOS, and nNOS in the injured skin and spinal cord dorsal horns through immunohistochemistry and Western assays. Furthermore, pro-inflammatory cytokines (IL-1 β and TNF-α) in the spinal cord were collected. Double immunofluorescent staining images for measuring p-IκB, p-NFκB, p-JNK, and TUNEL as well as Western blots of AKT, Bax/Bcl-2 for the inflammatory process, and apoptosis were analyzed. Fat grafting significantly reduced COX2, nNOS, and iNOS in the skin and spinal cord dorsal horns, as well as IL-1β and TNF-α, compared with the burn group. Moreover, regarding the anti-inflammatory effect, the apoptosis cells in the spinal cord significantly decreased after the fat grafting in the burn injury group. Fat grafting was effective in treating burn-induced neuropathic pain through the alleviation of neuroinflammation and ameliorated spinal neuronal apoptosis.

Abstract
Macrophages are involved in low-grade inflammation in diabetes, and play pathogenic roles in proliferative diabetic retinopathy (PDR) by producing proinflammatory cytokines. T cells as well as other cells are also activated by proinflammatory cytokines, and infiltration into the vitreous of patients with PDR has been shown. In this study, we measured helper T (Th) cell-related cytokines in the vitreous of PDR patients to define the characteristics of Th-mediated immune responses associated with PDR. The study group consisted of 25 type 2 diabetic patients (25 eyes) with PDR. The control group consisted of 27 patients with epiretinal membrane (ERM), 26 patients with idiopathic macular hole (MH), and 26 patients with uveitis associated with sarcoidosis. Vitreous fluid was obtained at the beginning of vitrectomy, and centrifuging for cellular removals was not performed. Serum was also collected from PDR patients. IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, soluble sCD40L, and TNFα in the vitreous and serum samples were measured. Both percent detectable and levels of IL-4, IL-6, IL-17A, IL-21, IL-22, and TNFα in the vitreous were significantly higher than those in the serum in PDR patients. Vitreous levels of these cytokines and IL-31 were significantly higher in PDR than in ERM or MH patients. Vitreous levels of IL-4, IL-17A, IL-22, IL-31, and TNFα in PDR patients were also significantly higher than those of sarcoidosis patients. In PDR patients, vitreous IL-17A level correlated significantly with vitreous levels of IL-22 and IL-31, and especially with IL-4 and TNFα. Although it is unclear whether these cytokines play facilitative roles or inhibitory roles for the progression of PDR, the present study indicated that Th2- and Th17-related immune responses are involved in the pathogenesis of PDR.

Abstract
AIMS/HYPOTHESIS Adipose tissue (AT) distribution is a major determinant of mortality and morbidity in obesity. In mice, intra-abdominal transplantation of subcutaneous AT (SAT) protects against glucose intolerance and insulin resistance (IR), but the underlying mechanisms are not well understood. METHODS We investigated changes in adipokines, tissue-specific glucose uptake, gene expression and systemic inflammation in male C57BL6/J mice implanted intra-abdominally with either inguinal SAT or epididymal visceral AT (VAT) and fed a high-fat diet (HFD) for up to 17 weeks. RESULTS Glucose tolerance was improved in mice receiving SAT after 6 weeks, and this was not attributable to differences in adiposity, tissue-specific glucose uptake, or plasma leptin or adiponectin concentrations. Instead, SAT transplantation prevented HFD-induced hepatic triacylglycerol accumulation and normalised the expression of hepatic gluconeogenic enzymes. Grafted fat displayed a significant increase in glucose uptake and unexpectedly, an induction of skeletal muscle-specific gene expression. Mice receiving subcutaneous fat also displayed a marked reduction in the plasma concentrations of several proinflammatory cytokines (TNF-α, IL-17, IL-12p70, monocyte chemoattractant protein-1 [MCP-1] and macrophage inflammatory protein-1β [ΜIP-1β]), compared with sham-operated mice. Plasma IL-17 and MIP-1β concentrations were reduced from as early as 4 weeks after transplantation, and differences in plasma TNF-α and IL-17 concentrations predicted glucose tolerance and insulinaemia in the entire cohort of mice (n = 40). In contrast, mice receiving visceral fat transplants were glucose intolerant, with increased hepatic triacylglycerol content and elevated plasma IL-6 concentrations. CONCLUSIONS/INTERPRETATION Intra-abdominal transplantation of subcutaneous fat reverses HFD-induced glucose intolerance, hepatic triacylglycerol accumulation and systemic inflammation in mice.

Abstract
Some neoplasms are associated with granulomatous inflammation. Granuloma formation in tumor tissue is caused by the cytokines derived from either the main tumor or other cells surrounding the tumor. In other instances, granulomatous inflammation is observed in the lymph nodes draining a tumor. This has been recognized as a sarcoid-like reaction. Herein, we report of a 75-year-old man with pulmonary squamous cell carcinoma (SCC), where granulomatous inflammation was observed extensively at the primary site. The carcinoma seemed to partly regress. In the regressing area, tumor cell debris was surrounded by granuloma. In contrast, no granuloma was identified in the dissected regional lymph nodes. To the best of our knowledge, such a case of SCC had not been described thus far. More case studies are required to determine whether tumor-related granuloma is the main cause of regression or whether it is just a secondary phenomenon caused by the attack and destruction of the tumor by lymphocytes.

Abstract
This study was aimed at understanding the histopathologic changes that occur in the nasal mucosa of patients with perennial allergic rhinitis after high-intensity focused ultrasound (HIFU) treatment. Biopsy specimens of the inferior turbinate mucosa were taken from 11 PAR patients before, immediately after and 1 y after HIFU treatment. Morphometric analysis revealed that the density of eosinophils and other inflammatory cells increased immediately after treatment and then were decreased significantly 1 y post-treatment. Submucosal glands were swollen and venous sinusoids were dilated, but there was no statistically significant change in their density, immediately after treatment. However, both glands and venous sinusoids significantly decreased in number 1 y after HIFU treatment. The ciliated epithelium or basement membrane of the nasal mucosa was well preserved at all stages. In conclusion, HIFU is a tolerable and effective treatment to reduce inflammation of the inferior turbinate mucosa in patients with perennial allergic rhinitis.

Abstract
Inflammatory myofibroblastic tumors are rare, and those located in the extremities without bone involvement are even rarer. We present the case of a 61-year-old Chinese male patient with an inflammatory myofibroblastic tumor of the right thigh. It was excised and a histopathologic examination revealed an inflammatory myofibroblastic tumor. This case is presented by virtue of its rare location.

Abstract
Low-grade inflammation links obesity, insulin resistance, and cardiovascular diseases. We investigated the effects of laparoscopic sleeve gastrectomy (LSG) on expression profile of genes involved in inflammatory pathways in subcutaneous adipose tissue (SCAT) and peripheral monocytes (PM). At baseline, obese group had significantly increased mRNA expression of proinflammatory chemokines (CCL-3, -17, -22), chemokine receptor CCR1 and cytokines (IL-10, IL-18) in SCAT and chemokine and other proinflammatory receptors (CCR-1, -2, -3, TLR-2, -4) in PM relative to control group. LSG decreased body weight, improved metabolic profile and reduced mRNA expression of up-regulated chemokine receptors, chemokines and cytokines in SCAT. In contrast, expression profiles in PM were largely unaffected by LSG. We conclude that LSG improved proinflammatory profile in subcutaneous fat but not in peripheral monocytes. The sustained proinflammatory and chemotactic profile in PM even 2 years after LSG may contribute to partial persistence of metabolic complications in obese patients after metabolic surgery.

Abstract
Ultrasonographic nerve enlargement has primarily been reported in patients with inflammatory neuropathies such as chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy, Guillain-Barre syndrome, vasculitic neuropathy and leprosy. Nerve ultrasonography is a promising diagnostic supportive tool for inflammatory neuropathies. The ultrasonographic findings that are currently useful are 1) nerve enlargement primarily suggests the existence of inflammatory or demyelinating neuropathies and 2) for patients with CIDP or demyelinating Charcot-Marie-Tooth disease, the pattern of nerve enlargement is noted, and this pattern is useful for discriminating between these diseases. More precise evidence of ultrasonographic findings for inflammatory neuropathies should be established in the future.

Abstract
In this study, we examine the clinicopathologic features of 104 cases of myxoinflammatory fibroblastic sarcoma (MIFS), a low-grade, inflammatory fibromyxoid tumor with a predilection to distal extremity soft tissue, and attempt to identify factors predictive of aggressive behavior. The study cohort consisted of 49 male and 55 female patients ranging in age from 17 to 83 (mean, 42; median, 39) years. The tumor arose primarily on the dorsal aspect of the distal extremities as a solitary and usually painless mass. Tumors ranged in size from 0.5 to 15 (mean, 3.2; median; 2.4) cm. Microscopically, tumors consisted of variably cellular and inflamed fibromyxoid tissue growing as a lobulated mass or as multiple nodules within subcutaneous tissue or along tendinofascial planes. Tumor cells ranged from plump spindled to more epithelioid cells with enlarged, vesicular nuclei. Characteristic of the process was a strikingly bizarre cell with an inclusion body-like nucleolus (85% of cases) and/or a smudgy hyperchromatic nucleus (51%) present in all but 7 cases. The mitotic rate per 50 high-power field ranged from 0 to 13 (mean, 2,9; median, 2) mitoses. Twenty-two tumors demonstrated 1 or more of the following atypical features: (1) foci with complex sarcoma-like vasculature; (2) hypercellular areas; and (3) increased mitotic activity or atypical mitotic figures. Immunohistochemically, tumor cells demonstrated immunoreactivity for vimentin (100%), D2-40 (86%), CD34 (50%), keratin(s) (33%), CD68 (27%), actin(s) (26%), desmin (9%), S-100 protein (7%), and epithelial membrane antigen (6%). Thirty of 59 patients (51%) with follow-up data suffered (at least) 1 local recurrence, and 1 patient developed metastatic disease after multiple local recurrences. Completeness of initial surgical excision was the only clinicopathologic parameter that statistically correlated with a lower incidence of recurrence (P=0.004). Histologically atypical MIFS recurred more often than conventional tumors (67% vs. 47%), but the difference was not statistically significant (P=0.35). Our study shows that histologic features often associated with more aggressive sarcomas do not substantially impact the morbidity of MIFS, and complete surgical excision provides the best chance for disease-free survival.
