Objective: The aim of this study was to observe the surgical wound healing process in patients with multiple myeloma who had undergone surgery. Method: We collected clinical data on patients with multiple myeloma and observed wound healing following surgical therapy. Additionally, we compared the expression of angiogenesis markers in patients with and without multiple myeloma (undergoing surgical excision of other tumour tissues). In patients who had multiple myeloma bone disease, we examined several clinical features: haemoglobin levels; albumin levels; blood glucose levels; and surgery programme. We then compared expression levels of the angiogenesis markers CD31, CD34 and vascular endothelial growth factor (VEGF) in samples scraped from the skin margin of the surgical incision in 12 patients without multiple myeloma (control) and nine patients with multiple myeloma. Results: All 61 patients with multiple myeloma observed showed no disunion, no delayed union and no infection in their wound healing. CD31 and VEGF expression was higher in the nine patients with multiple myeloma compared with the 12 control patients without. We observed no difference in CD34 expression between control and experimental groups. Conclusion: The results of this study suggest that patients with multiple myeloma who have undergone surgery recover well and produce higher quantities of new vessels compared with patients without multiple myeloma. This occurs through increased expression of CD31 and VEGF, angiogenic factors which promote wound healing. We did not observe higher expression of these factors contributing to increased incisional implantation metastasis. [ABSTRACT FROM AUTHOR]

Objective: Posterior fossa pediatric low-grade glioma involving the brainstem and cerebellar peduncles (BS-pLGG) are a subgroup with higher risks at surgery. We retrospectively analyzed the role of surgery in the interdisciplinary armamentarium of treatment options in our institutional series of BS-pLGG with various degrees of brainstem involvement. Material and methods: We analyzed data of 52 children with BS-pLGG after surgical intervention for clinical/molecular characteristics, neurological outcome, factors influencing recurrence/progression pattern, and tumor volumetric analysis of exclusively surgically treated patients to calculate tumor growth velocity (TGV). Tumors were stratified according to primary tumor origin in four groups: (1) cerebellar peduncle, (2) 4th ventricle, (3) pons, (4) medulla oblongata. Results: The mean FU was 6.44 years. Overall survival was 98%. The mean PFS was 34.07 months. Two patients had biopsies only. Fifty-two percent of patients underwent remission or remained in stable disease (SD) after initial surgery. Patients with progression underwent further 23 resections, 15 chemotherapies, 4 targeted treatments, and 2 proton radiations. TGV decreased after the 2nd surgery compared to TGV after the 1st surgery (p < 0.05). The resection rates were significantly higher in Groups 1 and 2 and lowest in medulla oblongata tumors (Group 4) (p < 0.05). More extended resections were achieved in tumors with KIAA1549::BRAF fusion (p = 0.021), which mostly occurred in favorable locations (Groups 1 and 2). Thirty-one patients showed postoperatively new neurological deficits. A total of 27/31 improved within 12 months. At the end of FU, 6% had moderate deficits, 52% had mild deficits not affecting activities, and 36% had none. Fifty percent of patients were free of disease or showed remission, 38% were in SD, and 10% showed progression. Conclusion: The first surgical intervention in BS-pLGG can control disease alone in overall 50% of cases, with rates differing greatly according to location (Groups 1 > 2 > 3 > 4), with acceptable low morbidity. The second look surgery is warranted except in medullary tumors. With multimodality treatments almost 90% of patients can obtain remission or stable disease after > 5 years of follow-up. An integrated multimodal and multidisciplinary approach aiming at minimal safe residual disease, combining surgery, chemo-, targeted therapy, and, as an exception, radiation therapy, is mandatory.

Glioblastoma (GBM) is the most common malignant primary brain tumor in adults. Despite an established standard of care including surgical resection, radiation therapy, and chemotherapy, GBM unfortunately is associated with a dismal prognosis. Therefore, researchers are extensively evaluating avenues to expand GBM therapy and improve outcomes in patients with GBM. In this review, we provide a broad overview of novel GBM therapies that have recently completed or are actively undergoing study in clinical trials. These therapies expand across medical, surgical, and radiation clinical trials. We additionally review methods for improving clinical trial design in GBM. [ABSTRACT FROM AUTHOR]

Background: Infectious endocarditis (IE) remains a critical condition despite all the medical advances in recent decades. Reliable pathogen identification is indispensable for precise therapy. The aim of this study was to evaluate the diagnostic and therapeutic benefit of additional polymerase chain reaction (PCR) in comparison with microbiological culture alone based on intraoperative tissue sampling for patients operated on due to IE. Methods: A total of 224 patients diagnosed with acute or subacute IE were analyzed. Intraoperatively resected infectious tissue was analyzed using both PCR and microbiological culture. Subsequently, the results of the detection of bacteria obtained based on intraoperative measurements from tissue via culture and PCR were compared with preoperative blood culture results. Furthermore, we evaluated the therapeutic impact of the culture and/or PCR results obtained from cardiac tissue. Results: The 224 patients were 63 ± 17 years old, and 64 (29%) were female. In total, 149 (67%) suffered from aortic valve endocarditis, 45 (45%) had mitral valve endocarditis, and 39 (18%) were afflicted with double-valve endocarditis. Prosthetic valve endocarditis was present in 70 (31%) patients. Pathogens were detected in 70% of the cases analyzed via PCR using cardiac valve tissue and in 25% of those analyzed via a culture of cardiac valve tissue; this figure was only 64% for preoperative blood culture. Overall, a pathogen was identified in 197 patients (88%), leading to antibiotic therapy. Targeted antibiotic therapy, based on the PCR results, was carried out in 37 cases and was conducted based on a culture from cardiac valve tissue in three cases. Finally, in 12% of patients, the causative pathogen remained unclear. Conclusions: For patients suffering endocarditis, PCR analysis is indispensable and superior to preoperative blood culture and intraoperative culture in detecting bacteria. Based on PCR testing, antibiotic therapy can be individually adjusted. The high precision of pathogen identification may lead to a significant reduction in IE-associated morbidity and mortality.

Practical relevanceFeline chronic gingivostomatitis (FCGS) is a debilitating disease for cats and a challenge for veterinarians and cat caregivers alike. Recent literature indicates that the disease is immune-mediated in nature and likely associated with a chronic viral infection in patients with higher alpha diversity of their subgingival microbiome. The immune-mediated nature of FCGS includes both local as well as systemic effects, and the transcriptomic analysis of affected patients supports these findings.Treatment optionsLocalized therapy in the form of surgical extraction of all, or nearly all, teeth continues to be the mainstay of treatment. For cats that do not respond to surgical management, medical management, in the form of immunosuppressive or immunomodulatory therapy, remains an option. Analgesia is of fundamental importance. Immunomodulation utilizing mesenchymal stromal cell therapy provides an alternative treatment avenue for refractory patients and likely targets the chronic viral infection present in this disease. The potential for treatment stratification and use of novel systemic treatment options may be revealed as the molecular pathways involved in this disease are better described.AimsThis review outlines current and emerging concepts linking available science pertaining to FCGS and clinical management of the disease.Evidence baseThe article draws on the best evidence base at this juncture and is also driven by the authors' collective experience of working on the disease for over a decade.

Background The difference in the prognoses between treatment with surgical therapy and continuation of local-plus-systemic therapy following successful down-staging of intermediate-advanced hepatocellular carcinoma (HCC) remains unclear. Methods Data of 405 patients with intermediate-advanced HCC treated at 30 hospitals across China from January 2017 to July 2022 were retrospectively reviewed. All patients received local-plus-systemic therapy and were divided into the surgical (n  = 100) and nonsurgical groups (n  = 305) according to whether they received surgical therapy. The differences between long-term prognoses of the 2 groups were compared. Subgroup analysis was performed in 173 HCC patients who met the criteria for surgical resection following down-staging. Results Multivariable analysis of all patients showed that surgical therapy, hazard ratio (HR): 0.289, 95% confidence interval, CI, 0.136-0.613) was a protective factor for overall survival (OS), but not for event-free survival (EFS). Multivariable analysis of 173 intermediate-advanced HCC patients who met the criteria for surgical resection after conversion therapy showed that surgical therapy (HR: 0.282, 95% CI, 0.121-0.655) was a protective factor for OS, but not for EFS. Similar results were obtained after propensity score matching. For patients with Barcelona Clinic Liver Cancer stage B (HR: 0.171, 95% CI, 0.039-0.751) and C (HR: 0.269, 95% CI, 0.085-0.854), surgical therapy was also a protective factor for OS. Conclusions Overall, for patients with intermediate-advanced HCC who underwent local-plus-systemic therapies, surgical therapy is a protective factor for long-term prognosis and can prolong OS, and for those who met the surgical resection criteria after conversion therapy, surgical therapy is recommended.

Aim: Medical therapy with antibiotics only and surgical drainage are the treatment options of tubo‐ovarian abscess (TOA). It is not yet known exactly which cases need surgical treatment. The aim of this systematic review and meta‐analysis was to evaluate the risk factors leading antibiotic therapy failure in women with TOA. Methods: We searched the following databases from inception to June 1, 2022: PubMed, Ovid MEDLINE, The Cochrane Library, and Scopus. We also searched reference lists of eligible articles and related review articles. The observational cohort, cross‐sectional, and case–control studies were included in the meta‐analysis. At least four review authors independently selected eligible articles, assessed risk of bias, and extracted data. The random effect model was used in the meta‐analysis. Results: A total of 29 studies, including 2890 women, were included in the study. The age, abscess size, history of intrauterine device use, postmenopausal status, history of diabetes mellitus, fever, white blood cell count, erythrocyte sedimentation rate, C‐reactive protein level, and history of pelvic inflammatory disease were found as significant risk factors for antibiotic therapy failure in women with TOA. Conclusions: The findings of this study clarified the risk factors for antibiotic therapy failure in women with TOA. [ABSTRACT FROM AUTHOR]

The persistent vitellointestinal duct is the rarest of all vitelline duct anomalies. This systematic literature review was undertaken to investigate and review the demographics, clinical presentation, surgical procedure performed, and outcome of infants who were operated upon for the persistent vitellointestinal duct. Infants with incomplete desired details, and children/cases operated upon for the above‑mentioned anomaly after infancy were excluded. Published literature/ manuscripts were retrieved for the previous fifty years from 1971 to December 2021, and the manuscripts were retrieved through an online database search. This review is presented in accordance with the preferred reporting items for systematic reviews and meta‑analyses (PRISMA) guidelines. A total of n = 280 infants who were operated upon for the patent vitelline duct were recruited for the systematic review. More than three‑fourths (n = 217, 77.5%) of infants were boys. Ninety percent of infants were under the age of 3 months, and 72% were neonates/newborn babies. Discharges through the umbilicus (n = 148; 52.85%), and prolapse of the bowel through the umbilicus (n = 117; 41.78%) were the chief complaints in the above‑mentioned infants. Operative procedures were performed (n = 280) in the following order of frequency: (1) resection of the persistent vitellointestinal duct, small adjacent segment of ileum, and ileo‑ileal anastomosis (n = 121, 43.21%); (2) resection of the persistent vitellointestinal duct, wedge resection of ileum, and ileal repair (n = 88; 31.42%); and (3) other surgical procedures (n = 11, 3.92%). Operative details were not clear/not available/not provided for n = 60 (21.42%) of the infants. Peri‑umbilical incisions were more frequently employed for surgical therapy. This review revealed postoperative death in n = 17 (6.07%) infants. The persistent vitellointestinal duct must be surgically resected at the earliest, preferably during the neonatal period.

Children and older adults are prone to unintentional foreign body aspiration. A 69‐year‐old man with fever and anorexia presented with obstructive pneumonia resulting from foreign body aspiration. Attempts to remove the foreign body using a bronchoscope failed due to its adhesion to the periphery of the bronchus. Although antibiotic therapy did not improve the obstructive pneumonia caused by the bronchial foreign body, surgery enabled an improvement. The surgical specimen showed similar pathological findings as the fine brown granular material observed in root granulomas occurring as a complication following leakage of root canal filling used in the treatment of dental caries. Therefore, the bronchial foreign body may have been a dental filling. Case reports describing surgical improvement of difficult‐to‐remove bronchial foreign bodies with concurrent infection are rare.

Periodontology has adapted over the years to demands for better healing, a more comfortable solution, treatment of marginal tissue recessions, and better aesthetics. This has become one of the main goals of this discipline. Platelet-enriched fibrin (PRF) is an autologous platelet concentrate similar to a scar matrix that guides the various cellular elements and releases growth factors and cytokines near the injury. It is an autogenous alternative to conjunctive grafting in treating gingival recession that would allow optimal healing quickly. This review presents the different types of PRF, the protocols for obtaining them, and the practical features of their surgical applications. The use of PRF in oral surgery signifies not just a trend but a fundamental shift towards patient-centered, evidence-based, and minimally invasive practices that redefine the boundaries of what is achievable in modern oral healthcare.

Background: Facial acne scars are a prevalent concern, leading to the development of various treatment modalities. Objectives: This review aims to explore the latest advancements in the treatment of facial acne scars, focusing on both surgical and non‐surgical methods. Methods: The non‐surgical treatments reviewed include topical medications (such as retinoids and alpha hydroxy acids) and non‐invasive procedures (like microdermabrasion and chemical peels). Surgical options discussed are punch excision, subcision, and fractional laser treatments. Results: Combination therapy, integrating both surgical and non‐surgical approaches, is frequently utilized to achieve optimal results in scar improvement. Conclusion: Recent advancements in the treatment of facial acne scars provide promising options for individuals seeking improvement. However, these treatments have associated risks and potential adverse effects, highlighting the importance of consulting a dermatologist before beginning any treatment regimen.

Introduction: The incidence of pneumonectomy for lung cancer in the UK is continuing to decline in the era of minimally invasive thoracic surgery totalling approximately 3.5% of lung cancer resections annually. Literature is lacking for long-term survival of pneumonectomies. This study updates our previous results. Between 1998 and 2008, 206 patients underwent pneumonectomy compared to 98 patients between 2009 and 2018. Methods: From January 1998 until December 2018, 304 patients underwent pneumonectomy. This was a retrospective study; data was analysed for age, gender, laterality, histology and time period. Results: Operative mortality was 4.3% overall which was lower than the national average of 5.8%. In the last five years, there were no in-hospital, operative or 30-day mortality. During this period, 90-day mortality was 9.2%. Left-sided pneumonectomies had significantly better overall survival (3.00 vs. 2.03 years; p = 0.0015), squamous cell carcinoma (3.23 vs. 1.54 years; p = 0.00012) as well as those aged less than 70 (2.79 vs. 2.13 years; p = 0.011). There was no significant difference in survival between gender (p = 0.48). Intervention from 1998 to 2008 had significantly greater survival compared to the latter 10 years (2.68 vs. 2.46 years; p = 0.031). The Cox model shows that laterality, age, histology and time period remain significant with multivariate testing. No patient survived after 16 years. Discussion: Our updated retrospective study has built on our previous results by reinforcing the success of pneumonectomies. The incidence of pneumonectomies is likely to decrease with the deployment of nation-wide lung cancer screening in the UK due to earlier detection. [ABSTRACT FROM AUTHOR]

Abstract Background The optimal treatment strategy for early‐stage hepatocellular carcinoma (HCC) remains controversial, specifically in regard to surgical resection (SR) and ablation. The aim of this study was to investigate the impact of SR and ablation on recurrence and prognosis in early‐stage HCC patients, to optimize treatment strategies and improve long‐term survival. Methods A retrospective analysis was conducted on 801 patients diagnosed with Barcelona Clinic Liver Cancer (BCLC) stage 0/A HCC and treated with SR or ablation between January 2015 and December 2019. The effectiveness and complications of both treatments were analyzed, and patients were followed up to measure recurrence and survival. Propensity score matching (PSM) was employed to increase comparability between the two groups. The Kaplan–Meier method was used to analyze recurrence and survival, and a Cox risk proportional hazard model was used to identify risk factors that affect recurrence and surviva. Results Before PSM, the overall survival (OS) rates were similar in both groups, with recurrence‐free survival (RFS) rates better in the SR group than in the ablation group. After PSM, there was no significant difference in OS between the two groups. However, the RFS rates were significantly better in the SR group than in the ablation group. The ablation group exhibited superior outcomes compared to the SR group, with shorter treatment times, reduced bleeding, shorter hospital stays, and lower hospital costs. Concerning the location of the HCC within the liver, comparable efficacy was observed between SR and ablation for disease located in the noncentral region or left lobe. However, for HCCs located in the central region or right lobe of the liver, SR was more effective than ablation. Conclusions This study revealed no significant difference in OS between SR and ablation for early‐stage HCC, with SR providing better RFS and ablation demonstrating better safety profiles and lower hospital costs. These findings offer valuable insights for clinicians in determining optimal treatment strategies for early‐stage HCC patients, particularly in terms of balancing efficacy, safety, and cost considerations.

Biochemical recurrence (BCR) following radical prostatectomy (RP) has a limited ability to predict prostate cancer (PC) progression, leading to overtreatment, decreased quality of life, and additional expenses. Previously, we established that one-third of men with BCR in our group experienced low-risk recurrences that were safely observed without treatment. Our retrospective cohort analysis of 407 BCR patients post RP validates the use of PSA doubling time (DT) kinetics to direct active observation (AO) versus treatment following RP. The primary outcome was no need for treatment according to the predictive value of models of ROC analysis. The secondary outcome was PC-specific mortality (PCSM) according to Kaplan−Meier analysis. A total of 1864 men underwent RP (June 2002−September 2019); 407 experienced BCR (PSA > 0.2 ng/dL, ×2), with a median follow-up of 7.6 years. In adjusted regression analysis, initial PSADT > 12 months and increasing DT were significant predictors for AO (p < 0.001). This model (initial PSADT and DT change) was an excellent predictor of AO in ROC analysis (AUC = 0.83). No patients with initial PSADT > 12 months and increasing DT experienced PCSM. In conclusion, the combination of PSADT > 12 months and increasing DT was an excellent predictor of AO. This is the first demonstration that one-third of BCRs are at low risk of PCSM and can be managed without treatment via DT kinetics.

Abstract Background Cytomegalovirus (CMV) infection, often subclinical in childhood, is reactivated during a state of cell-mediated immunodeficiency. In cases of organ damage, patients can require medical treatment for an infectious disease, generally through the use of antiviral drugs. There are no reports of surgical treatment in cases, where infection was found, and medical treatment was difficult. We encountered a case of CMV enteritis that was difficult to treat because of resistance to antivirals but improved after total colectomy. Case presentation A previously healthy, 74-year-old woman visited a doctor with a chief complaint of watery diarrhea persisting for 2 weeks; she was transferred to our hospital because of hypoxemia and hypovolemic shock. Computed tomography scan indicated wall thickening over the entire colon and the patient was diagnosed with infectious colitis. Conservative and antibacterial therapies were started with fasting fluid replacement. Subsequently, bloody stools were observed 11 days after admission. Colonoscopy was then performed, which showed mucosal edema and longitudinal ulcer, while a histopathological examination of the colon mucosa revealed C7HRP positive on 22 days after admission. CMV enteritis was diagnosed, and the antiviral medication, ganciclovir, was started. Diseases causing immunosuppression and other possible causes of enteritis were also closely examined; however, all were negative. Furthermore, the patient’s symptoms and her endoscopic findings did not improve with ganciclovir administration; therefore, the antiviral drug was changed to foscarnet. Unfortunately, the patient did not improve despite the additional administration of gamma globulin and methylprednisolone, and she was determined to have enteritis resistant to medical therapy. A total colon resection was performed 88 days after the admission. Her condition gradually stabilized postoperatively, and oral intake was initiated and tolerated. The patient was transferred to another hospital for rehabilitation for home discharge. She is now at home and has had no recurrences. Conclusions In previous reports of surgical treatment for CMV enteritis, many cases were initially undiagnosed, emergency surgery was performed after perforation or stenosis was recognized, and then CMV was diagnosed and treated. In CMV enteritis without immunodeficiency, surgical treatment may be an option if medical treatment is ineffective.

Simple Summary: Central nervous system lymphoma is a rarity among brain tumours. The clinical course depends on location and size of the tumour. Various established treatments, including chemotherapy, radiation, and stem cell transplantation, are available. The resection of intracranial lesions is still under discussion. In our retrospective analysis, we were able to show that compared to the sole confirmation of diagnosis through stereotactic biopsy, the resection of the lesion offered a significant advantage in patient survival. Especially for singular, easily accessible lesions, resection in addition to radiotherapy/chemotherapy could have a benefit. Our findings substantiate earlier research outcomes and shall lay the foundation for forthcoming prospective investigations. Background: Central nervous system lymphoma (CNSL) is rare form of brain tumour. It manifests either as primary CNS lymphoma (pCNSL) originating within the central nervous system or as secondary CNS lymphoma (sCNSL), arising as cerebral metastases of systemic lymphoma. For a significant period, surgical resection was considered obsolete due to the favourable response to chemotherapy and the associated risk of postoperative deficits. The objective of the present study was to demonstrate the benefits of resection in CNSL patients, including extended survival and improved postoperative function. Methods: A retrospective study involving patients diagnosed with either PCNSL or SCNSL that were surgically approached at our neurosurgical department between 2010 and 2022 was conducted. Patients were categorised into three subgroups based on their neurosurgical approach: (1) stereotactical biopsy, (2) open biopsy, (3) resection. We then performed statistical analyses to assess overall survival (OS) and progression-free survival (PFS). Additionally, we examined various secondary factors such as functional outcome via Karnofsky Performance Index (KPS) and prognosis scoring. Results: 157 patients diagnosed with PCNSL or SCNSL were enclosed in the study. Of these, 101 underwent stereotactic biopsy, 21 had open biopsy, and 35 underwent resection. Mean age of the cohort was 64.94 years, with majority of patients being female (54.1%). The resection group showed longest OS at 44 months (open biopsy = 13 months, stereotactic biopsy = 9 months). Calculated median follow-up was 34.5 months. In the Cox regression model, postoperative KPS 70% (p < 0.001) and resection vs. stereotactic biopsy (p = 0.040) were identified as protective factors, whereas older age at diagnosis was identified as a risk factor (p < 0.001). In the one-way analysis of variance, differences in postoperative KPS were found among all groups (p = 0.021), while there was no difference in preoperative KPS among the groups. Conclusions: Our data show a favourable outcome when resection is compared to either stereotactic or open biopsy. Additionally, the marginally improved postoperative functional status observed in patients who underwent resection, as opposed to in those who underwent biopsy, provides further evidence in favour of the advantages of surgical resection for enhancing neurological deficits.

Purpose: Treatment of neuroblastoma metastases usually consists of chemotherapy and irradiation. However, in selected cases, surgical treatment is also indicated. In this study, we present three cases of patients with neuroblastoma metastases at rare sites that underwent surgery. Materials and methods: We retrospectively analyzed data of patients who underwent surgery for neuroblastoma at our department of Pediatric Surgery and Pediatric Urology at the University Children's Hospital in Tuebingen and selected those patients who had surgery explicitly for a metastasis. Results: Between 2002 and 2020, 277 children underwent surgical treatment for neuroblastoma. Three cases with metastases at exceptional sites are presented here after therapy according to protocols. One patient had a penile metastasis and received surgery including a plastic reconstruction. The patient showed no signs of erectile or urinary dysfunction at follow-up. Another patient had a metastasis in the proximal ulna, which remained vital even after exhausted treatment after two relapses. Afterward there was no restriction of movement of the extremity. The third patient had, amongst others, metastases to the pancreatic body and to the liver. Both were surgically removed during primary tumor resection. This patient died after local tumor relapse. The other two patients showed no evidence of tumor relapse after a follow-up of 18 and 17 months, respectively. Conclusion: Although children with neuroblastoma often present with metastases, there is no recommendation for surgical treatment other than diagnostic biopsies. In case of persistence of metastasis or after exhaustion of high-risk therapy, surgical resection must be considered. [ABSTRACT FROM AUTHOR]

Aim: To identify predictors of treatment outcomes following surgical therapy of peri‐implantitis. Materials and Methods: We performed a secondary analysis of data from a randomized controlled trial (RCT) comparing access flap with or without bone replacement graft. Outcomes at 12 months were probing pocket depth (PPD), bleeding on probing (BOP), soft‐tissue recession (REC) and marginal bone level (MBL) change. Multilevel regression analyses were used to identify predictors. We also built an explanatory model for residual signs of inflammation. Results: Baseline PPD was the most relevant predictor, showing positive associations with final PPD, REC and MBL gain, and negative association with probability of pocket closure. Smokers presented higher residual PPD. Absence of keratinized mucosa at baseline increased the probability of BOP but was otherwise not indicative of outcomes. Plaque at 6 weeks was detrimental in terms of residual PPD and BOP. Treatment allocation had an effect on REC. Final BOP was explained by residual PPD ≥6 mm and plaque at more than two sites. Conclusions: Baseline PPD was the most relevant predictor of the outcomes of surgical therapy of peri‐implantitis. Pocket closure should be a primary goal of treatment. Bone replacement grafts may be indicated in aesthetically demanding cases to reduce soft‐tissue recession. The importance of smoking cessation and patient‐performed plaque control is also underlined.

Introduction: Malignant pleural mesothelioma (MPM) is a rare condition with a poor survival rate. This study was designed to determine the prognostic importance of glucose transporter-1 (GLUT-1) expression in operated patients with pleural mesothelioma. Methods: Patients operated with a diagnosis of pleural mesothelioma between January 2005 and September 2014 were retrospectively analyzed in terms of age, gender, diagnosis method, maximum standardized uptake value in positron emission tomography, operation, pathology, GLUT-1 expression in the specimen, morbidity, and mortality. Results: One hundred and twenty-nine patients were diagnosed as MPM. 75 (54 male and 21 female) of these patients underwent therapeutic operations. The mean age was 63 (range 41-89). Extrapleural pneumonectomy was performed in 27, pleurectomy/decortication in 25, and radical pleurectomy in 23 patients. The pathological diagnosis was epithelial in 67 and biphasic in 8 patients. All the patients were referred for adjuvant chemoradiotherapy and 69% completed the intended trimodality treatment. In 61 (81.3%) of the operated patients, the parietal pleura material was positive for GLUT-1. The morbidity was seen in 16 of the operated patients. The average survival time was 23.7 months after surgery. The average survival time was 24.5 months in patients with GLUT-1 expression <10% in extent, and 15.6 months in rest of the patients (p=0.001). Discussion and Conclusion: MPM has a poor prognosis even after surgery. However, lower expression of GLUT-1 was associated with significantly longer survival in our study.

Abstract Background Two cases of orbitofrontal cholesterol granuloma masquerading as frontal sinus mucoceles were reported to understand image findings, clinical and histopathologic features of orbitofrontal cholesterol granuloma to improve its diagnosis and treatment. Case presentation Two East Asian patients aged 41 and 27 without personal or familial medical or trauma history presented with the common complaint of proptosis and inferomedial displacement of the eyeballs. The computed tomography (CT) of both cases showed an irregularly shaped, well-defined lesion in the left frontal bone associated with bony erosion. The lesions resulted in the bone absorption of frontal bone and orbital roof, which extended into the superior orbital space. Anterior orbitotomy through subbrow incision by drainage and curettage resulted in a curative outcome. The histopathological examination revealed inflammatory granulation tissues, fibrous capsule wall, cholesterol clefts with altered blood pigments, and calcifications, consistent with the diagnosis of cholesterol granuloma. No recurrence was observed for one year after surgery in one case and three years in the other. Conclusions When the following features are observed: orbital CT exhibits cystic lesion with irregular bone destruction in the superolateral orbit, magnetic resonance imaging (MRI) depicts lesions are hyperintense signals on T1 weighted images (T1WI), and T2 weighted images (T2WI), and the contrast-enhanced imaging reveals that the most of tumor is showed a non-significant enhancement, orbitofrontal cholesterol granuloma should be considered.

Keloid is a pathological scar that is higher than the skin surface following skin damage. Its lesion range often extends beyond the original damage boundary and does not naturally subside over time. Its pathogenesis is very complex, currently the main causes include fibroblast excessive proliferation, collagen and extracellular matrix (Extracellular matrix, ECM) excessive deposition, excessive angiogenesis, and so on. The traditional treatment method primarily involves surgical intervention, but it is associated with a high recurrence rate post-surgery. Consequently, many treatment methods are derived according to the different clinical characteristics of keloid. This paper will review the therapeutic progress in recent years from surgical treatment, physiotherapy, drug therapy, and biological therapy, with the goal of offering valuable insights for the clinical treatment of keloids.

Abstract Background Phyllodes tumor (PT) is a solid fibroepithelial breast lesion with proliferation of stromal and epithelial elements, usually presents with a rapidly expanding feature. Venous thromboembolism (VTE) have been reported to increase the burden in terms of mortality and morbidity of malignant tumor, and associate with worsened survival. However, benign PTs with silent thromboembolism that have not yet been reported, we report an unusual case of massive benign PT that grew on the left side of the breast in a cauliflower‐shaped form and presented severe chronic blood loss and deep VTE. Case A 37‐year‐old woman with uncontrolled pain presented a rapidly enlarging left breast mass, measuring approximately 30 × 20 × 15 cm3 that first started 25 years ago. color Doppler ultrasound showed a large mass lesion on the left breast and deep VTE, several enlarged lymph nodes in the left axilla and mediastinum, which presented a malignant character. However, the biopsies of the mass did not show evidence of malignancy and the pathology result was considered to be benign PT. The patient was treated with an inferior vena cava and anticoagulation, the operation was arranged according to the surgical procedure, the patient recovered very well after mastectomy. Conclusion This case is unique in that the giant breast mass presented with malignant character, was eventually pathologically confirmed to be benign PT, and it's rare that the benign tumor accompanied with silent thromboembolism. This finding describes the atypia features of giant benign PT and reminds the surgeon to consider the factor of VTE and risk when encountering ulcerative benign breast tumor and avoid excessive treatment.

Introduction: Analysis of the 3‐dimensional implant position, the bone defect morphology, and the soft tissue situation guides the decision to preserve or to remove an implant with a severe peri‐implantitis lesion. The aim of this narrative review was to analyze and to comprehensively illustrate the treatment options focusing on peri‐implant bone regeneration in presence of severe peri‐implant bone loss. Methods: A database search was performed independently by the two reviewers to identify case reports, case series, cohort, retrospective, and prospective studies about peri‐implant bone regeneration with a follow‐up of at least 6 months. Of the 344 studies issued during the database analysis, 96 publications were selected by the authors for this review. Results: Deproteinized bovine bone mineral remains the best documented material for defect regeneration in peri‐implantitis in combination with or without a barrier membrane. While studies using autogenous bone in peri‐implantitis therapy are rarely found, they do report favorable potential of vertical bone regeneration. Moreover, while membranes are an inherent part of the guided bone regeneration, a 5‐year follow‐up study demonstrated clinical and radiographic improvements with and without a membrane. The administration of systemic antibiotics is frequently performed in clinical studies observing regenerative surgical peri‐implantitis therapy, but the analysis of the literature does not support a positive effect of this medication. Most studies for regenerative peri‐implantitis surgery recommend the removal of the prosthetic rehabilitation and the use a marginal incision with a full‐thickness access flap elevation. This allows for a good overview for regenerative procedures with a certain risk of wound dehiscences and incomplete regeneration. An alternative approach referring to the poncho technique may reduce the risk of dehiscence. The effectiveness of implant surface decontamination might have an impact on peri‐implant bone regeneration without any clinical superiority of a certain technique. Conclusion: The available literature reveals that the success of peri‐implantitis therapy is limited to the reduction of bleeding on probing, the improvement of the peri‐implant probing depth and a small amount of vertical defect fill. On this basis, no specific recommendations for bone regeneration in surgical peri‐implantitis therapy can be made. Innovative approaches for flap design, surface decontamination, bone defect grafting material, and soft tissue augmentation should be followed closely to find advanced techniques for favorable peri‐implant bone augmentation.

Background: Peri‐implantitis constitutes one of the most frequent late dental implant complications. The disease is initiated by bacterial infection; therefore, anti‐infective peri‐implantitis treatment strategies are required to arrest the progressive marginal bone loss and maintain the affected implant in function. Although nonsurgical treatment strategies appear to be of limited predictability, treatment outcomes have been frequently improved following surgical interventions. Purpose: The present narrative review describes various surgical peri‐implantitis treatment modalities, with respect to their indications, performance, and effectiveness. Materials and Methods: The present narrative review considered the most relevant studies in the field published in the English language. Results: Surgical peri‐implantitis treatment approaches can be categorized as nonreconstrucive therapy, reconstructive therapy, and combined therapy (ie, reconstructive and resective therapy). In addition to disease resolution, reconstructive approaches also seek to regenerate the bone defect and achieve reosseointegration. Conclusions: The severity of the disease, the regenerative potential of the defetc and esthetic demands of the patient are the factors determining the surgical peri‐implantitis treatment modality.

Feline chronic gingivostomatitis is a frustrating disease to manage owing to its elusive etiopathogenesis and its subsequently suboptimal treatment options. Nevertheless, efforts to shed light on the disease over the past few decades have advanced the knowledge on its potential etiopathogenesis and the success rates of available treatment options. Further research is ongoing, with promising attempts to better understand and treat this, likely, multifactorial disease.

Abstract Backround Endometriosis is one of the most common gynecological illnesses causing extensive psychological, physical and social impact on patient’s life and exerts negative effects on health-related quality of Life (HRQoL). However, the effects of surgery on the postoperative HRQoL in the different endometriosis subgroups have not been fully evaluated. Methods We performed a comparative retrospective study between 2014 and 2018 at the Medical University of Vienna, including all patients with surgically confirmed endometriosis who had completed the standardized Endometriosis Health Profile-30 (EHP-30) questionnaire 1 day after surgery (the questions refer to the 4 weeks preoperatively) and 6–10 weeks postoperatively. Results Compared to preoperative values, we found significant benefits, regarding postoperative conditions, in our study group (n = 115) in all five categories, “pain” (HR 0.78, p

Abstract Background The cysts of the male pelvic floor represent a rare clinical entity. Their origin is linked to an altered development of paramesonephric and mesonephric ducts during embryogenesis. Case presentation We report our experience regarding two patients presenting cysts of the ejaculatory system treated with open and mini-invasive surgery. The patients referred to our clinic with nonspecific symptoms and the diagnosis was obtained by radiological investigations. The patient treated with an open approach developed a pelvic purulent collection and a fistula of the prostatic urethra, managed with surgical drainage and prolonged bladder catheterization. On the other hand, the patient treated with laparoscopic approach did not develop any complications. No sexual or ejaculatory disorders were reported. Conclusions Patients with congenital cysts of the pelvic floor must be adequately informed about the risks and benefits of surgery and a careful counseling is mandatory before surgery. Treatment is recommended for symptomatic patients and an endoscopic approach is associated with a high rate of recurrence. A laparoscopic approach, when possible, is desirable.

Introduction: Several surgical techniques for chronic instability of the peroneal tendons have been reported. Yet, the most optimal technique has not been clarified. This study aims to perform a systematic review and meta-analysis of all existing evidence and compare all published surgical techniques in both the athletic as the nonathletic population. Materials and methods: A systematic review and a proportional meta-analysis, with a random-effects model, were carried out according to the PRISMA guidelines, using the keywords "chronic luxation" OR "instability" AND "peroneal tendon" AND "treatment" OR "treatment protocol". Four surgical techniques were compared in patients with chronic peroneal instability, comprising superior peroneal retinaculum (SPR) repair or replacement, groove deepening procedures (primarily with additional SPR operations), rerouting procedures, and bony procedures (respectively group S, G, R and B). Outcomes of interest include the pre- and postoperative American orthopedic foot and ankle society hindfoot score, return to sports, postoperative redislocation and complications. Pooled estimates of the last two outcomes were obtained. Results: For the systematic review, 31 studies were eligible. Of these, 25 papers met the criteria for inclusion in the meta-analysis. All techniques demonstrated a clinical improvement postoperatively. Group B, however, demonstrated overall more unsatisfactory results, and higher complication rates were observed for both group R and group B. The latter was established by the proportional meta-analysis as well [95% confidence interval group S: (0.01–0.10); group G: (0.02–0.10); group R: (0.13–0.57); group B: (0.24–0.40)]. Concerning surgical efficacy (= no postoperative redislocation), no significant difference was statistically observed. Finally, considerable differences in study quality were identified. Conclusion: Surgical treatment results in excellent clinical and functional outcomes in patients with chronic peroneal instability. More inferior results were demonstrated for rerouting and bony procedures. However, no high-quality studies are available and future randomized controlled trials are necessary to advocate for the most advantageous approach. [ABSTRACT FROM AUTHOR]

Background: Osteosarcomas are the most common primary bone tumor while occurrence in the craniofacial skeleton is relatively rare. There are clinical differences of osteosarcomas regarding their location. In this regard craniofacial osteosarcomas (COS) have special characteristics. Extracranial osteosarcomas (EOS) occur mainly in the long bones of the extremities (tibia, humerus and femur). These tumors metastasize hematogenically at a very early stage. In comparison, COS are mainly localized in the mandible and maxilla, occur later in life and show significantly less and later metastasis and respond differently to adjuvant therapy. In the literature, clinical characteristics of COS and EOS are rarely compared directly. The aim of this systematic review is to answer the question whether COS and EOS exhibit fundamentally different clinical behavior and how they differ in terms of survival rates and response to different therapies. Methods: A systemic review was performed. Pubmed, Cochrane and Google Scholar were used as search engines. The literature research was done by using clearly defined terms and their links. 124 full texts were selected and evaluated for this review. The inclusion criteria were determined using the PICO model. Results: COS have significantly better survival rates, especially if they are located in the jawbone. Surgical R0 resection is crucial for therapeutic success. The study situation regarding the benefit of neoadjuvant chemotherapy in COS is very inhomogeneous. There is also no evidence for the benefit of adjuvant radio- or chemotherapy in COS. The large heterogeneity of the studies in terms of therapeutic concept, initial situation of the patients and outcome considered, as well as the small number of patients with craniofacial osteosarcoma were limiting factors. Conclusion: The results of this study show the clear therapeutic and prognostic differences between COS and EOS and underline the necessity to consider both types of osteosarcoma as independent tumor entities in future studies. Furthermore, the study highlights the importance of surgical R0 resection for the prognosis of COS patients. There is no evidence for therapeutic benefit of adjuvant/neoadjuvant radio-/chemotherapy in R0 resected COS cases. [ABSTRACT FROM AUTHOR]

Abstract Background Etiology of hyperlactatemia in ICU patients is heterogeneous—septic, cardiogenic or hemorrhagic shock seem to be predominant reasons. Multiple studies show hyperlactatemia as an independent predictor for ICU mortality. Only limited data exists about the etiology of hyperlactatemia and lactate clearance and their influence on mortality. The goal of this single-center retrospective study, was to evaluate the effect of severe hyperlactatemia and reduced lactate clearance rate on the outcome of unselected ICU surgical patients. Methods Overall, 239 surgical patients with severe hyperlactatemia (> 10 mmol/L) who were treated in the surgical ICU at the University Medical Center Freiburg between June 2011 and August 2017, were included in this study. The cause of the hyperlactatemia as well as the postoperative course and the patient morbidity and mortality were retrospectively analyzed. Lactate clearance was calculated by comparing lactate level 12 h after first measurement of > 10 mmol/L. Results The overall mortality rate in our cohort was 82.4%. Severe hyperlactatemia was associated with death in the ICU (p
