    Background We sought to reduce local recurrence for retroperitoneal sarcomas by using a coordinated strategy of advanced radiation techniques and aggressive en-bloc surgical resection. Methods Proton-beam radiation therapy (PBRT) and/or intensity-modulated radiation therapy (IMRT) were delivered to improve tumor target coverage and spare selected adjacent organs. Surgical resection of tumor and adjacent organs was performed to obtain a disease-free anterior margin. Intraoperative electron radiation therapy (IOERT) was delivered to any close posterior margin. Results Twenty patients had primary tumors and eight had recurrent tumors. Tumors were large (median size 9.75 cm), primarily liposarcomas and leiomyosarcomas (71%), and were mostly of intermediate or high grade (81%). PBRT and/or IMRT were delivered to all patients, preferably preoperatively (75%), to a median dose of 50 Gy. Surgical resection included up to five adjacent organs, most commonly the colon (n = 7) and kidney (n = 7). Margins were positive for disease, usually posteriorly, in 15 patients (54%). IOERT was delivered to the posterior margin in 12 patients (43%) to a median dose of 11 Gy. Surgical complications occurred in eight patients (28.6%), and radiation-related complications occurred in four patients (14%). After a median follow-up of 33 months, only two patients (10%) with primary disease experienced local recurrence, while three patients (37.5%) with recurrent disease experienced local recurrence. Conclusions Aggressive resection of retroperitoneal sarcomas can achieve a disease-negative anterior margin. PBRT and/or IMRT with IOERT may possibly deliver sufficient radiation dose to the posterior margin to control microscopic residual disease. This strategy may minimize radiation-related morbidity and reduce local recurrence, especially in patients with primary disease. PMID:20151216

    Background Periodontitis can be defined as a local inflammatory process which mediates destruction of periodontal tissues & is triggered by bacterial insult. In periodontal infections, the levels of C reactive proteins are elevated as compared to the levels in a periodontally healthy individual. The study was done to determine the relative levels of serum CRP in aggressive, chronic and periodontally healthy subjects and to evaluate the effect of surgical periodontal therapy on serum C-reactive protein levels. Materials and Methods Serum samples were collected from 150 participants (50 healthy control patients (non-periodontitis), 50 patients with chronic periodontitis and aggressive periodontitis. Serum C- reactive protein levels were assessed by means of immunoturbidimetric assay at baseline for subjects in all the 3 groups and 3 months after completion of surgical therapy. Results The mean baseline C-reactive protein (CRP) concentrations in the Groups I, II and III were 1.65±0.57 mg/L, 3.03±2.14 mg/L and 3.09±2.27 mg/L respectively. After treatment, the mean C-reactive protein (CRP) levels in Groups II and III reduced from 3.03±1.67 mg/L to 1.46±1.67 mg/L and from 3.09±1.21 to 1.43±1.21 mg/L respectively. Similar results were found for probing depth and all indexes in Group II and III after treatment. Also, the mean attachment loss in Groups II and III reduced, so the results were highly significant. Conclusion Successful periodontal treatment results in significant decrease in serum C-reactive protein (CRP) levels in otherwise healthy subjects. PMID:26557605

    Increasing evidence suggests that two factors significantly influence outcome in a surgical emergency – premorbid health and the degree of inflammation during the first 24 h following trauma. Repeat observations suggest that the depth of post-trauma immunoparalysis reflects the height of early inflammatory response. Administration to surgical emergencies, as was routine in the past, of larger amounts of fluid and electrolytes, fat, sugar and nutrients seems counterproductive as it increases immune dysfunction, impairs resistance to disease and, in fact, increases morbidity. Instead, strong efforts should be made to limit the obvious superinflammation, which occurs during the first 24 h after trauma and, thereby, reduce the subsequent immuno-paralysis. paralysis. Several approaches show efficacy in limiting early superinflammation such as strict control of blood glucose, avoida nce of stored blood when possible, supply of antioxidants, live lactic acid bacteria and plant fibres. This review focuses mainly on use of live lactic acid bacteria and plant fibres, often called synbiotics. Encouraging experience is reported from clinical trials in liver transplantation, severe pancreatitis and extensive trauma. Immediate control of inflammation by enteral nutrition and supply of antioxidants, lactic acid bacteria and fibres is facilitated by feeding tubes, introduced as early as possible on arrival at the hospital.

    There is still no other therapeutic management for echinococcosis of the liver than surgical treatment. Indeed, drug therapy with Mebendazol prevents parasitosis from spreading. However, a complete regression has not been observed hitherto. Surgical procedure is dependent on expansion, localisation and type of echinococcosis. Generally, cystectomy is possible and adequate in case of Echinococcus granulosus, in case of Echinococcus multilocularis with its infiltrating growth, a complete healing can only be attained by lobectomy. With the hilus being invaded and obstructive jaundice proceeding, an improvement can be reached by Mebendazol or a palliative endless drainage tube. PMID:4013541

    Differentiated thyroid carcinomas (DTCs) that arise from follicular cells account >90% of thyroid cancer (TC) [papillary thyroid cancer (PTC) 90%, follicular thyroid cancer (FTC) 10%], while medullary thyroid cancer (MTC) accounts <5%. Complete total thyroidectomy is the treatment of choice for PTC, FTC, and MTC. Radioiodine is routinely recommended in high-risk patients and considered in intermediate risk DTC patients. DTC cancer cells, during tumor progression, may lose the iodide uptake ability, becoming resistant to radioiodine, with a significant worsening of the prognosis. The lack of specific and effective drugs for aggressive and metastatic DTC and MTC leads to additional efforts toward the development of new drugs. Several genetic alterations in different molecular pathways in TC have been shown in the past few decades, associated with TC development and progression. Rearranged during transfection (RET)/PTC gene rearrangements, RET mutations, BRAF mutations, RAS mutations, and vascular endothelial growth factor receptor 2 angiogenesis pathways are some of the known pathways determinant in the development of TC. Tyrosine kinase inhibitors (TKIs) are small organic compounds inhibiting tyrosine kinases auto-phosphorylation and activation, most of them are multikinase inhibitors. TKIs act on the aforementioned molecular pathways involved in growth, angiogenesis, local, and distant spread of TC. TKIs are emerging as new therapies of aggressive TC, including DTC, MTC, and anaplastic thyroid cancer, being capable of inducing clinical responses and stabilization of disease. Vandetanib and cabozantinib have been approved for the treatment of MTC, while sorafenib and lenvatinib for DTC refractory to radioiodine. These drugs prolong median progression-free survival, but until now no significant increase has been observed on overall survival; side effects are common. New efforts are made to find new more effective and safe compounds and to personalize the therapy in

    2014-01-01

    Purpose Aggressive periodontitis, especially in its severe form, was traditionally considered to have an unfavourable prognosis. It required a complex treatment and its stabilization was often achieved by surgical therapy. The aim of this study was to investigate the results of nonsurgical periodontal treatment in severe generalized forms of aggressive periodontitis. Methods Patients with advanced generalized aggressive periodontitis were included in the study. Probing depth (PD) of pockets ≥7 mm and clinical attachment level (CAL) of sites with attachment loss ≥5 mm were measured at baseline before nonsurgical periodontal treatment, at re-evaluation, and after treatment. The following other parameters were recorded: resolution of inflammation and bone fill. We compared the baseline values with re-evaluation and posttreatment values using the Friedman test. The Wilcoxon test with the Bonferroni correction was used for both re-evaluation and posttreatment values. Results Seven patients with 266 periodontal sites were examined. A significant difference was found between values, reported as medians with interquartile ranges, for PD at baseline (7.94 [7.33-8.19] mm) and both re-evaluation (4.33 [3.63-5.08] mm) and posttreatment (3.54 [3.33-4.11] mm) values (P=0.002). A significant difference was also found between values for CAL at baseline (9.02 [7.5-9.2] mm) and both re-evaluation (6.55 [6.30-6.87] mm) and posttreatment (6.45 [5.70-6.61] mm) (P=0.002). Inflammation was resolved and angular bone defects were repaired in all cases. Conclusions These therapeutic results suggest that this form of periodontitis could have positive outcomes after nonsurgical periodontal treatment. The reparative potential of tissue affected by severe aggressive periodontitis should encourage clinicians to save apparently hopeless teeth in cases of this form of periodontitis.

    2013-01-01

    Neoadjuvant treatment in terms of preoperative radiotherapy reduces local recurrence in rectal cancer, but this improvement has little if any impact on overall survival. Currently performed optimal quality-controlled total mesorectal excision (TME) surgery for patients in the trial setting can be associated with very low local recurrence rates of less than 10% whether the patients receive radiotherapy or not. Hence metastatic disease is now the predominant issue. The concept of neoadjuvant chemotherapy (NACT) is a potentially attractive additional or alternative strategy to radiotherapy to deal with metastases. However, randomised phase III trials, evaluating the addition of oxaliplatin at low doses plus preoperative fluoropyrimidine-based chemoradiotherapy (CRT), have in the main failed to show a significant improvement on early pathological response, with the exception of the German CAO/ARO/AIO-04 study. The integration of biologically targeted agents into preoperative CRT has also not fulfilled expectations. The addition of cetuximab appears to achieve relatively low rates of pathological complete responses, and the addition of bevacizumab has raised concerns for excess surgical morbidity. As an alternative to concurrent chemoradiation (which delivers only 5–6 weeks of chemotherapy), potential options include an induction component of 6–12 weeks of NACT prior to radiotherapy or chemoradiation, or the addition of chemotherapy after short-course preoperative radiotherapy (SCPRT) or chemoradiation (defined as consolidation chemotherapy) which utilises the “dead space” of the interval between the end of chemoradiation and surgery, or delivering chemotherapy alone without any radiotherapy.

    The purpose of this study was to compare the effect of tooth related and patient related factors on the success of non-surgical and surgical periodontal therapy. In 41 patients (22 female) with untreated and/or recurrent periodontitis, no therapy, scaling and root planing (SRP), or access flap (AF) were assigned according to probing pocket depth (PPD). PPD and vertical relative attachment level (RAL-V) were obtained initially, 3 and 6 months after therapy. Baseline data were compared according to therapy, jaw, tooth type, and site. Factors influencing clinical parameters were identified using multilevel analyses. Baseline PPDs were deeper interproximally, in the maxilla and at premolars compared to buccal/oral sites, mandibular, and anterior teeth. At 6 months, PPD reduction and RAL-V gain were significantly greater at sites receiving SRP and AF as compared to untreated sites (p < 0.001). PPD reduction and RAL-V gain were significantly less (p < 0.005) in smokers as compared to nosmokers and at interproximal sites (p < 0.0001) as compared to buccal/oral sites. RAL-V gain was less in aggressive periodontitis, and PPD reduction was less in the maxilla (p < 0.001). In sites with greater bone loss and infrabony defects, a poorer response was observed regarding RAL-V gain or PPD reduction, respectively. The conclusions of the study are the following: (1) Nonsurgical and surgical periodontal therapies are effective in single-rooted teeth; (2) severe interproximal bone loss and infrabony defects deteriorate clinical results; and (3) there seem to be more defect-associated (tooth, site) factors influencing treatment outcome than patient-associated factors.

    Faecal incontinence is a common condition and is associated with considerable morbidity and economic cost. The majority of patients are managed with conservative interventions. However, for those patients with severe or refractory incontinence, surgical treatment might be required. Over the past 20 years, numerous developments have been made in the surgical therapies available to treat such patients. These surgical therapies can be classified as techniques of neuromodulation, neosphincter creation (muscle or artificial) and injection therapy. Techniques of neuromodulation, particularly sacral nerve stimulation, have transformed the management of these patients with a minimally invasive procedure that offers good results and low morbidity. By contrast, neosphincter procedures are characterized by being more invasive and associated with considerable morbidity, although some patients will experience substantial improvements in their continence. Injection of bulking agents into the anal canal can improve symptoms and quality of life in patients with mild-to-moderate incontinence, and the use of autologous myoblasts might be a future therapy. Further research and development is required not only in terms of the devices and procedures, but also to identify which patients are likely to benefit most from such interventions. PMID:24275793

    2014-10-01

    The post-thrombotic syndrome (PTS), long-term sequelae of a deep vein thrombosis (DVT), reduces quality of life and is of great socio-economic importance. Despite conservative treatment which does not directly facilitate recanalization more than 25% of patients develop PTS. Early thrombus removal may decrease the incidence and severity of PTS. Although the evidence for surgical thrombectomy is weak which allows an early and rapid recanalization, this therapy appears to reduce the risk of PTS and iliofemoral thrombosis. Systemic thrombolysis can reduce the incidence of PTS but it is no longer recommended due to serious bleeding complications. Previous studies with new endovascular catheter-guided procedures allowing local application of thrombolysis and thrombus aspiration displayed promising results. However, so far one prospective randomised study (CaVent study) with long-term results has revealed a significant reduction of PTS. The current evidence recommends early thrombus removal for patients at high risk for PTS. New endovascular procedures such as catheter-guided thrombolysis allow rapid thrombus removal but more prospective randomised studies are necessary to ensure the long-term success of this therapy.

    Atrial fibrillation is the most common sustained arrhythmia and is associated with significant risks of thromboembolism, stroke, congestive heart failure, and death. There have been major advances in the management of atrial fibrillation including pharmacologic therapies, antithrombotic therapies, and ablation techniques. Surgery for atrial fibrillation, including both concomitant and stand-alone interventions, is an effective therapy to restore sinus rhythm. Minimally invasive surgical ablation is an emerging field that aims for the superior results of the traditional Cox-Maze procedure through a less invasive operation with lower morbidity, quicker recovery, and improved patient satisfaction. These novel techniques utilize endoscopic or minithoracotomy approaches with various energy sources to achieve electrical isolation of the pulmonary veins in addition to other ablation lines. We review advancements in minimally invasive techniques for atrial fibrillation surgery, including management of the left atrial appendage. PMID:22666609

    Between January 1st 1990 and December 31st 1999, 24 patients affected by Klatskin tumor underwent operation in our department of surgery. According to Bismuth's classification, there were 0 (0%) type I, 5 (21%) type II, 6 (25%) type IIIa, 4 (17%) type IIIb and 9 (37%) type IV tumors. Five patients (21%) were treated by curative resection (group I) while in 14 patients (58%) palliative surgical procedure was performed (group II). In 5 cases (21%) the extension of malignancy did not allowed any procedure (group III). Curative resection for malignant tumors of the hepatic duct bifurcation included wide tumor excision and bile duct resection at the liver hilum (with wedge hepatic resection in one patient) and creation of biliary-enteric anastomosis. Palliative surgical procedure included stent insertion. Jaundice was completely relieved in all patients undergoing resection, since 3 patients (21%) after stenting hadn't satisfactory biliary drainage. There was 1 (20%) perioperative death in the group 1, while in group 2, 5 patients (36%) died postoperatively. In this series, the mean postoperative survival of all patients was 16 months. The mean postoperative survival of patients undergoing localized tumor resection with curative intent was 38 months, in contrast to 10 months for those undergoing operative stent insertion. in addition, only 1 patient from group III, in whom only exploratory surgery were performed survived 7 months, while other 4 patients died in the hospital. This retrospective review suggests that aggressive surgical treatment could improve survival and quality of life in patients suffering from Klatskin tumor. PMID:15636089

    Backgrounds/Aims Aggressive surgical resection for hepatic metastasis is validated, however, concomitant liver and lung metastasis in colorectal cancer patients is equivocal. Methods Clinicopathologic data from January 2008 through December 2012 were retrospectively reviewed in 234 patients with colorectal cancer with concomitant liver and lung metastasis. Clinicopathologic factors and survival data were analyzed. Results Of the 234 patients, 129 (55.1%) had synchronous concomitant liver and lung metastasis from colorectal cancer and 36 (15.4%) had metachronous metastasis. Surgical resection was performed in 33 patients (25.6%) with synchronous and 6 (16.7%) with metachronous metastasis. Surgical resection showed better overall survival in both groups (synchronous, p=0.001; metachronous, p=0.028). In the synchronous metastatic group, complete resection of both liver and lung metastatic lesions had better survival outcomes than incomplete resection of two metastatic lesions (p=0.037). The primary site of colorectal cancer and complete resection were significant prognostic factors (p=0.06 and p=0.003, respectively). Conclusions Surgical resection for hepatic and pulmonary metastasis in colorectal cancer can improve complete remission and survival rate in resectable cases. Colorectal cancer with concomitant liver and lung metastasis is not a poor prognostic factor or a contraindication for surgical treatments, hence, an aggressive surgical approach may be recommended in well-selected resectable cases.

    Giant cell granuloma (GCG) is an uncommon bony lesion in the head and neck region, most commonly affecting the maxilla and mandible and has a female predilection. The clinical behavior of central GCG ranges from a slowly growing asymptomatic swelling to an aggressive lesion. The clinical, radiological, histological features and management of an aggressive GCG of maxilla in an 18-year-old female patient are described and discussed. It is emphasized that surgery is the traditional and still the most accepted treatment for GCG. Le Fort I osteotomy has been advocated as one of the access osteotomy for the surgical management of aggressive and extensive GCG involving the maxilla. The postoperative morbidity and recurrence have been discussed. PMID:22754742

    2008-12-01

    Charcot neuro-osteoarthropathy (CN) is among the most devastating complications of neuropathy and now most commonly occurs in the feet of diabetic patients. Because it is relatively rare and because most patients and practitioners do not expect major bone pathology in the absence of significant pain, CN is often misdiagnosed as cellulitis, deep venous thrombosis, or gout. Also, radiographs early in the process are often relatively unremarkable. Although MRI findings are characteristic, treatment should not wait for the MRI result. The hot swollen erythematous neuropathic foot suspected to be CN should be emergently mechanically protected, usually in an irremovable total contact cast. Mechanical protection is the mainstay of conservative therapy, but surgical reconstruction of a deformed foot can usually also be successful. Unless diagnosed very early, significant decrements in quality of life result. Controlled studies are urgently needed to identify best practices. PMID:18990300

    AIM: To investigate the influence of nodal status on response and clarify the optimal treatment for operable esophageal squamous cell carcinoma (OSCC). METHODS: We retrospectively analyzed 1490 OSCC patients who underwent transthoracic esophagectomy and lymphadenectomy between December 1996 and December 2009 at the Sun Yat-sen University Cancer Center. The surgical approach and the number of resected lymph nodes (LNs) were considered in the assessment of surgery. Patients were classified according to their nodal statuses (N0 vs N1 vs N2-3). Overall survival was defined as the time from the date of death or final follow-up. Survival analysis was performed using the Kaplan-Meier method and differences between curves were assessed by the log-rank test. Univariate and multivariate Cox regression analyses were used to identify factors associated with prognosis. Statistical significance was assumed at a P < 0.05. RESULTS: With a median time from surgery to the last censoring date for the entire cohort of 72.2 mo, a total of 631 patients were still alive at the last follow-up and the median survival time was 35.5 mo. The surgical approach (left transthoracic vs Ivor-Lewis/tri-incisional) was verified as independent prognostic significance in patients with N0 or N1 status, but not in those with N2-3 status. Similar results were also observed with the number of resected LNs (≤ 14 vs ≥ 15). Compared with surgery alone, combined therapy achieved better outcomes in patients with N1 or N2-3 status, but not in those with N0 status. For those with N2-3 status, neither the surgical approach nor the number of resected LNs reached significance by univariate analysis, with unadjusted HRs of 0.826 (95%CI: 0.644-1.058) and 0.849 (95%CI: 0.668-1.078), respectively, and aggressiveness of surgery did not influence the outcome; the longest survival was observed in those patients who received the combined therapy. CONCLUSION: Combined therapy has a positive role in OSCC with LN

    Operations due to benign thyroid diseases are one of the most common elective surgical procedures performed in Germany. In the majority of cases, the preoperative determination of the serum thyrotropin concentration and an ultrasound of the thyroid region are sufficient preoperative investigations. In cases of thyroid functional disorders a scintigram should be additionally performed. Indications for operation in nodular goiter are local, mechanical compression, suspicion of malignancy and focal or disseminated autonomy. In Graves' disease the indication for operation is usually recurrent hyperthyroidism after medical treatment. In endemic nodular goiter the morphology of the nodular thyroid tissue is the guideline for resection; i.e. all nodules have to be removed. In Graves' disease the function of the remaining thyroid tissue is essential. The standardized subtotal resection with remaining tissue around the hilus, which frequently barries nodules, should be avoided. Instead a selective resection which takes the individual morphology and function of the diseased thyroid tissue into account should be favorized. With this operative technique the surgeon will have frequently direct contact with the recurrent nerve and the parathyroids. It is documented, that intraoperative visualisation of the recurrent nerve decreases not only the rate of permanent nerve damages but increases as well the completeness of resection. Additionally, ligation of the inferior thyroid artery decreases the incidence of residual or recurrent disease without enlarging the risk of postoperative parathyroiprive hypocalcemia. An individual follow-up with iodine and/or thyroxine replacement therapy is an indispensable component of the surgical therapeutic approach. The target of thyroxine substitution in patients after resection due to benign thyroid diseases is a physiologic serum thyrotropin concentration (0.3 to 4.0 mU/l). PMID:9542021

    A series of 300 pulmonary resections in patients with lung carcinoma is presented. Total survival rate of the series since the operation, including surgical mortality, was 33% at 3 years and 24% at 5 years. The survival rate and surgical criteria were correlated, having better results when standard surgery was performed. The authors emphasize that the surgical figures of the series are of great value as the surgical indications were large and nonselective, with 85% of resectability in the thoracotomies. PMID:229985

    Lying between the carotid bifurcation and the jugular foramen, glomus vagale tumors share characteristics with paragangliomas of those two structures, such as invasion of the carotid artery, destruction of the skull base, and cranial neuropathies. This capability for local invasion provides a therapeutic challenge with regard to the proper assessment of tumor extent and the selection of appropriate treatment. In order to clarify an approach to the management of glomus vagale tumors, we reviewed a 10-year experience with 15 patients treated for this tumor at the University of Zürich Department of Otolaryngology, using a new system of classification. This system highlights the relative position of a vagal paraganglioma to the jugular foramen and is helpful in designing the proper therapy. Pitfalis in surgical technique, recommended preoperative evaluation, and the roles of balloon occlusion and irradiation in the treatment of these tumors, are discussed.

    Uterine serous carcinoma (USC) is a highly aggressive variant of endometrial cancer. Although it only represents less than 10% of all cases, it accounts for a disproportionate number of deaths from endometrial cancer. Comprehensive surgical staging followed by carboplatin and paclitaxel chemotherapy represents the mainstay of USC therapy. Vaginal cuff brachytherapy is also of potential benefit in USC. Recent whole-exome sequencing studies have demonstrated gain of function of the HER2/NEU gene, as well as driver mutations in the PIK3CA/AKT/mTOR and cyclin E/FBXW7 oncogenic pathways in a large number of USCs. These results emphasize the relevance of these novel therapeutic targets for biologic therapy of chemotherapy-resistant recurrent USC. PMID:24328598

    Deep infiltrating endometriosis of the rectum is a severe disease concerning young women of reproductive age. Because it is a benign condition, aggressive surgical treatment and subsequent complications are not always accepted by young patients. Two surgical approaches exist: the radical approach, employing colorectal resection; and the conservative approach, based on rectal shaving or full-thickness disc excision. At present, the majority of patients with rectal endometriosis worldwide are managed by the radical approach. Conversely, as high as 66% of patients with colorectal endometriosis can be managed by either rectal shaving or full-thickness disc excision. Most arguments that used to support the large use of the radical approach may now be disputed. The presumed higher risk of recurrence related to conservative surgery can be balanced by a supposed higher risk of postoperative bowel dysfunction related to the radical approach. Bowel occult microscopic endometriosis renders debatable the hypothesis that more aggressive surgery can definitively cure endometriosis. Although most surgeons consider that radical surgery is unavoidable in patients with rectal nodules responsible for digestive stenosis, conservative surgery can be successfully performed in a majority of cases. In multifocal bowel endometriosis, multiple conservative procedures may be proposed, provided that the nodules are separated by segments of healthy bowel of longer than 5 cm. Attempting conservation of a maximum length of rectum may reduce the risk of postoperative anterior rectal resection syndrome and subsequent debilitating bowel dysfunction and impaired quality of life. Promotion of less aggressive surgery with an aim to better spare organ function has become a general tendency in both oncologic and benign pathologies; thus the management of deep colorectal endometriosis should logically be concerned, too.

    OBJECTIVES To determine if aggressive treatment initiated early in the course of rheumatoid factor positive or negative polyarticular juvenile idiopathic arthritis (poly-JIA) can induce clinical inactive disease (CID) within 6 months. METHODS Between May 2007 and October 2010 a multi-center, prospective, double blind, randomized, placebo controlled trial of two aggressive treatments was conducted in 85 children aged 2 to 16 years with polyarticular JIA of less than 12 months duration. Patients received either methotrexate 0.5 mg/kg/wk SQ (40 mg max), etanercept 0.8 mg/kg/wk (50 mg max), prednisolone 0.5 mg/kg/d (60 mg max) tapered to 0 by 17 weeks (Arm 1), or methotrexate (same dose as Arm 1), etanercept placebo, and prednisolone placebo (Arm 2). The primary outcome was CID at 6 months. An exploratory phase determined the rate of clinical remission on medication (6 months of continuous CID) at 12 months. RESULTS By 6 months, 17 of 42 (40%) of patients in Arm 1 and 10 of 43 (23%) in Arm 2 had achieved CID (X2 = 2.91; p = 0.088). After 12 months, 9 patients in Arm 1 and 3 in Arm 2 achieved clinical remission on medication (p = 0.0534). There were no significant inter-arm differences in adverse events. CONCLUSIONS Although this study did not meet its primary endpoint, early aggressive therapy in this cohort of children with recent onset polyarticular JIA resulted in substantial proportions of patients in both arms achieving CID by 6 months and clinical remission on medication within 12 months of treatment.

    Objectives The recurrence of meningiomas is a crucial aspect that must be considered during the planning of treatment strategy. The Simpson grade classification is the most relevant surgical aspect to predict the recurrence of meningiomas. We report on a series of patients with recurrent skull base meningiomas who were treated with the goal of radical removal. Design A retrospective study. Setting Hospital Ernesto Dornelles, Porto Alegre, Brazil. Participants Patients with recurrent skull base meningiomas. Main Outcomes Measures The goal of obtaining aggressive resection (i.e., Simpson grades I and II). Results The average age was 54 years, the mean follow-up period was 52.1 months, and Simpson grades I and II were obtained in 82%. The overall mortality was 5.8%. Transient cranial nerve deficits occurred in 11.7%; the definitive morbidity was also 5.8%. A second recurrence occurred in 5.8%. Conclusions Radical removal of recurrent skull base meningiomas is achievable and should be considered an option with a good outcome and an acceptable morbidity. The common surgical finding that was responsible for recurrence in this study was incomplete removal during the first surgery. We recommend extensive dura and bone removal in the surgical treatment of such recurrent lesions. PMID:27175316

    It is estimated that 10% to 20% of patients with pancreatic cancer present with resectable disease. Although surgery offers curative intent, the median survival after curative resection is less than 2 years. To improve clinical outcomes in this patient population, clinical studies have investigated the role of perioperative therapy, including neoadjuvant and adjuvant treatment in resectable pancreatic cancer. The role of adjuvant therapy has been well established by large randomized phase III studies, whereas benefit of the neoadjuvant approach remains inconclusive. Here, we review various treatment modalities and their clinical benefits in resectable pancreatic cancer. PMID:26226906

    Fifty-two patients underwent coronary artery bypass grafting between 1973 and 1979 for variant angina, defined as pain, usually at rest, associated with S-T segment elevation. Only patients with fixed occlusive coronary artery disease, defined as greater than 70% narrowing in diameter, were included. When fixed coronary artery stenosis is present, variant angina--whether presenting as stable, unstable, or postinfarction angina, and regardless of the number of vessels diseased--is effectively treated by myocardial revascularization. Preoperative intraaortic balloon pumping is a useful therapeutic adjunct in the unstable subset refractory to medical therapy. The results of revascularization in patients with Prinzmetal's variant angina and fixed coronary disease were no different from those in patients with classic angina pectoris of comparable clinical categories.

    Background: Aggression is a kind of behavior that causes damage or harm to others. The prevalence of aggression is 8–20% in 3–6 years old children. The present study aimed to assess the effect of training kindergarten teachers regarding reinforcement behavior therapy on preschoolers’ aggression. Methods: In this cluster randomized control trial, 14 out of 35 kindergarten and preschool centers of Mohr city, Iran, were chosen using random cluster sampling and then randomly assigned to an intervention and a control group. All 370 kindergarten and preschool children in 14 kindergarten were assessed by preschoolers’ aggression questionnaire and 60 children who obtained a minimum aggression score of 117.48 for girls and 125.77 for boys were randomly selected. The teachers in the intervention group participated in 4 educational sessions on behavior therapy and then practiced this technique under the supervision of the researcher for two months. Preschoolers’ aggression questionnaire was computed in both intervention and control groups before and after a two-month period. Results: The results demonstrated a significant statistical difference in the total aggression score (P=0.01), verbal (P=0.02) and physical (P=0.01) aggression subscales scores in the intervention group in comparison to the control group after the intervention. But the scores of relational aggression (P=0.09) and impulsive anger (P=0.08) subscales were not statistically different in the intervention group compared to the controls. Conclusion: This study highlighted the importance of teaching reinforcement behavior therapy by kindergarten teachers in decreasing verbal and physical aggression in preschoolers.

    Pseudofolliculitis barbae (PFB) is a common, chronic, inflammatory skin disorder seen mainly in individuals with curly hair. This condition is seen most frequently in black men who shave their beards but may also be seen in women of all races who wax or shave the axillary and pubic skin. The etiology of PFB is multifactorial, and heretofore a cure has been considered impossible for those desiring a clean-shaven face. The following article serves to discuss the current medical and surgical therapies available for this condition. Medical treatments for this condition include various combinations of topical antibiotics, corticosteroids, and retinoids. In the surgical arena, laser therapy has revolutionized the treatment of PFB and has enabled cure for the first time for those plagued by this disorder and for whom a beardless face is acceptable.

    Constipation is a highly prevalent disorder that affects people regardless of age, race, gender, or socioeconomic status. For many patients, constipation is a chronic condition that reduces quality of life. Chronic constipation also imposes a significant economic burden on the health care system. The treatment of constipation remains problematic for both patients and providers for a variety of reasons, including a lack of specificity of symptoms, an inconsistent relationship between underlying pathophysiology and symptom generation, and different and unpredictable patient responses to medications. A large number of over-the-counter agents are used to treat symptoms of constipation, although many of these agents are not effective, and data to support their use are limited and generally of poor quality. Patients referred for consultation typically have failed therapy with over-the-counter agents and require prescription medications or possibly even surgical therapy.

    In the approximately 1% of children affected by epilepsy, pharmacoresistance and early age of seizure onset are strongly correlated with poor cognitive outcomes, depression, anxiety, developmental delay, and impaired activities of daily living. These children often require multiple surgical procedures, including invasive diagnostic procedures with intracranial electrodes to identify the seizure-onset zone. The recent development of minimally invasive surgical techniques, including stereotactic electroencephalography (SEEG) and MRI-guided laser interstitial thermal therapy (MRgLITT), and new applications of neurostimulation, such as responsive neurostimulation (RNS), are quickly changing the landscape of the surgical management of pediatric epilepsy. In this review, the authors discuss these various technologies, their current applications, and limitations in the treatment of pediatric drug-resistant epilepsy, as well as areas for future research. The development of minimally invasive diagnostic and ablative surgical techniques together with new paradigms in neurostimulation hold vast potential to improve the efficacy and reduce the morbidity of the surgical management of children with drug-resistant epilepsy.

    Monopolar transurethral resection of the prostate (TURP) with endoscopic electrocautery remains the gold standard surgical technique for benign prostatic hypertrophy (BPH) by which all new procedures are compared. We reviewed the current literature, and international urological guidelines and consensus opinion on various surgical options for BPH and present a brief overview of alternative techniques including bipolar TURP, transurethral incision of the prostate, transurethral vaporization of the prostate, laser prostatectomy (with holmium, thulium and potassium titanyl phosphate greenlight lasers) and open prostatectomy (with mention of new techniques including laparoscopic and robotic prostatectomy). Emerging, experimental and less established techniques are also described including endoscopic heat generation (transurethral microwave thermotherapy, radiofrequency transurethral needle ablation of the prostate, high intensity focused ultrasound, hot water induced thermotherapy, pulsed electromagnetic radiofrequency), injection therapy (transurethral ethanol ablation and botulinum toxin) and mechanical devices (intraprostatic stents and urethral lift devices). Despite a plethora of surgical options, none have realistically improved outcomes in the long-term compared with TURP. Improvements have been made on improving surgical morbidity and time in hospital. Questions remain in this area, including what specific elements of bladder outflow obstruction (BOO) result in damage to the urinary tract, how does BPH contribute to BOO and how much prostate volume reduction is necessary to relieve BOO or lower urinary tract symptoms. Given these unanswered questions and the multitude of procedures available, it is clear that appropriate counselling is necessary in all men who undergo BPH surgery. PMID:24744521

    Despite recent medical progress primary and secondary lymphedemas still represent a therapeutic challenge and they often lead to a significant reduction in quality of life. Lymphedemas usually develop in the extremities, the male external genitals as well as the female breast as a consequence to the axial alignment of the lymphatic collectors. Early stages are characterized by an excess of lymph fluid increasing the volume of the affected part of the body whereas later stages represent an increasing amount of solid tissue. Thus therapeutic efforts can focus on the reduction of the surplus of liquid and/or solid components. Generally there are conservative and operative strategies. Conservative measures mainly focus on the improvement of fluid mobilization and drainage and comprise compression garments, manual lymphatic drainage, and apparative intermittent compression. Operative approaches comprise procedures for surgical tissue reduction (symptomatic/ablative approaches) and/or procedures with the intention of enhancing lymphatic transport (causal approaches). Surgical tissue reduction can be performed by open resection and/or liposuction. Traditional surgical causal techniques such as transposition of local flaps aim at leading lymph away from the congested region of the body. Modern microsurgical causal approaches contain methods of reconstruction of interrupted lymphatic pathways as well as techniques for the conduction of lymph into local veins. In this review we depict and discuss the features of the multiform spectrum of the surgical therapy of lymphedemas on the basis of literature as well as our own clinical and experimental experience.

    Several extensive surgical interventions of a cystic lesion in the left mandible were followed by recurrences. The lesion extended from the primary mandibular region into the area of pterygopalatine fossa finally infiltrating the orbital region and the skull base. Histological results could never demonstrate a malignancy with certainty. Due to the patient's poor general condition, the refusal for further surgical inventions and due to the malignoma-like growth pattern radiation treatment was performed. However, this had no effect on tumor progression. PMID:21845481

    Lipid formulations of amphotericin B remain the first-line antifungal therapy for invasive mucormycosis. Posaconazole is an alternative for salvage therapy, but its use as primary therapy is not recommended due to the paucity of clinical data. Here we describe the case of a 57-year-old diabetic woman receiving etanercept and prednisone for the treatment of psoriatic arthritis who developed primary cutaneous mucormycosis after a minor gardening injury. Infection was successfully treated with aggressive surgical debridement followed by a 6-week course of the new delayed-release tablet formulation of posaconazole and temporary withholding of anti-TNF treatment. Primary antifungal therapy with posaconazole can be considered in selected cases of cutaneous mucormycosis. PMID:26112998

    Chronic anticoagulant treatment is administered mostly for cardiological reasons. Cumarin derivatires are used in the majority of cases (Warfarin, Pelentan). It is necessary to monitor this treatment regularly and to control the dose according to the INR value. Different complications can occur; the haemorrhage represents a serious one. The authors discuss several aspects of anticoagulant therapy and possible prevention of the complications. The importance of the problems is demonstrated on the authors' clinical experience--two cases of haemorrhage after Warfarin administration simulating an acute surgical event. PMID:11482149

    One hundred women treated for carcinoma of the cervix were interviewed more than one year later to establish the effects of radiation or surgical therapy on sexual function. Forty-three had received irradiation, 44 nonradical surgery, six combined surgery and irradiation, and seven radical surgery. The irradiation and nonradical surgery groups were each further subdivided into subgroups of patients aged 30 to 49 for age-controlled comparison. Patients in the irradiation group had statistically significant decreases in sexual enjoyment, ability to attain orgasm, coital opportunity, frequency of intercourse, and coital desire. The group who had nonradical surgical procedures had no significant change in sexual function after treatment. Similar results were found in both age-controlled subgroups, eliminating age as a major etiologic factor. Marked vaginal alterations were recorded in the majority of irradiated patients, but were not present among the groups treated with nonradical surgery. The vaginal changes alone could not be held accountable for the significant decrease in sexual function among women who received pelvic irradiation. The origin of decreased sexual desire after radiation therapy is complex, and not yet completely understood. We propose therapeutic programs to help women deal with the emotional and physical consequences of pelvic irradiation.

    In 5-10% of cases ascites is not controlled by medical therapy and is defined refractory. These patients may be submitted to one of the four following surgical options: portal-systemic shunt, peritoneo-venous shunt, transjugular intrahepatic portal-systemic shunt, orthotopic liver transplantation. Although the portal-systemic shunt is efficient in clearing ascites, it does not improve the survival, which depends on liver function, and it is complicated by an important incidence of encephalopathy. Since the patients with refractory ascites and good hepatic risk are not usually many, it is possible to understand why derivative surgery has been disappointing with this indication. Although the peritoneo-venous shunt is associated with a significant rate of valve obstruction, it is an easy, effective and not expensive treatment. So, till now, it has been considered the first choice procedure of refractory ascites, if any situations, determinating the onset of postoperative complications, are not present. Recently a new method has been introduced in the therapy of portal hypertension, the transjugular intrahepatic portal-systemic shunt. This is a bloodless portal-systemic derivation and so it has caused great enthusiasm even if the available data are insufficient to give a definitive opinion on its role in management of ascites. Certainly the liver transplantation, which presents the great advantage to treat both the cirrhosis and its complications, seems to be the most rational therapy for these patients. However, at least for this moment, the well-known absence of organ donors makes still actual the palliative surgical measures. PMID:9489332

    Hair loss is a common problem that challenges the patient and clinician with a host of cosmetic, psychological and medical issues. Alopecia occurs in both men and women, and in all racial and ethnic populations, but the etiology varies considerably from group to group. In black women, many forms of alopecia are associated with hair-care practices (e.g., traction alopecia, trichorrhexis nodosa, and central centrifugal cicatricial alopecia). The use of thermal or chemical hair straightening, and hair braiding or weaving are examples of styling techniques that place African American women at high risk for various "traumatic" alopecias. Although the exact cause of these alopecias is unknown, a multifactorial etiology including both genetic and environmental factors is suspected. A careful history and physical examination, together with an acute sensitivity to the patient's perceptions (e.g., self-esteem and social problems), are critical in determining the best therapy course. Therapeutic options for these patients range from alteration of current hair grooming practices or products, to use of specific medical treatments, to hair replacement surgery. Since early intervention is often a key to preventing irreversible alopecia, the purpose of the present article is to educate the dermatologist on all aspects of therapy for hair loss in black women--including not only a discussion of the main medical and surgical therapies but also an overview of ethnic hair cosmetics, specific suggestions for alterations of hair-care practices, and recommendations for patient education and compliance.

    Atrial fibrillation and heart failure commonly coexist in the same patient. Each may adversely affect the other. Atrial fibrillation leads to heart failure exacerbation, left ventricular function deterioration and an increase in thrombo-embolic risk. Therapeutic options targeting atrial fibrillation in heart failure patients include pharmacological and non-pharmacological means. Pharmacological therapy is directed at either rate control using nodal blocking agents or rhythm control using anti-arrhythmic agents, of which the options are limited in patients with heart failure. The landmark AF-CHF trial did not show any benefit of rhythm control strategy as opposed to rate control in patients with heart failure and atrial fibrillation. However, patients in this trial as well as in others used mostly amiodarone for rhythm control. This might have negated any positive effects of achieving normal sinus rhythm. Non-pharmacological therapy both for rate and rhythm control is appealing. This includes AV node ablation for rate control, catheter ablation of atrial fibrillation and surgical therapy of atrial fibrillation. This review will address non-pharmacologic treatment of AF in heart failure patients. PMID:24132645

    Background and Objective Prospective studies that investigated the influence of surgical and nonsurgical procedures in the recurrence of periodontitis and tooth loss in periodontal maintenance therapy (PMT) programs have not been previously reported. The objective of this study was to evaluate longitudinally the recurrence of periodontitis in regular compliers (RC) and irregular compliers (IC) individuals undergoing surgical and non-surgical procedures over 5 years in a program of PMT. Materials and Methods A total of 212 individuals participated in this study. Full-mouth periodontal examination including bleeding on probing, probing depth, and clinical attachment level were determined at all PMT visits over 5 years. The recurrence of periodontitis was evaluated in RC and IC individuals undergoing surgical and non-surgical procedures in PMT. The influences of risk variables of interest were tested through univariate analysis and multivariate logistic regression. Results Recurrence of periodontitis was significantly lower among RC when compared to IC. Individuals with recurrence of periodontitis and undergoing surgical procedures showed higher probing depth and clinical attachment loss than those who received non-surgical procedures. Recurrence of periodontitis was higher in individual undergoing surgical procedures and irregular compliance during PMT. Conclusions Irregular compliance and surgical procedures in individuals undergoing PMT presented higher rates of recurrence of periodontitis when compared to regular compliant patients undergoing non-surgical procedures.

    Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.

    We seek to confirm the effect and explore the indications of aggressive locoregional management in patients with metastatic inflammatory breast cancer (IBC). Between 2003 and 2014, we reviewed the records of 156 patients with metastatic IBC from five large centers of Breast Surgery in the region of central south of China. Clinicopathologic data were collected to access overall survival (OS), prognostic factors and the indications for locoregional treatment. 75 (48%) patients underwent aggressive locoregional therapy. Patients in locoregional therapy group had a median OS of 24 months compared with 17 months of those in no locoregional therapy group. 2-year OS rate of these two groups was 52% and 32%, separately. Locoregional therapy (HR = 0.556; 95% CI 0.385-0.803; p = 0.002) was confirmed to be an independent prognostic factor, which could significantly improve OS of patients with metastatic IBC. For locoregional therapy group, statistical differences were observed in all subgroups stratified by the factors that were significant in univariate analysis except in the subgroups of stable disease, Charlson comorbidity index ≥3 and cerebral metastasis. Therefore, systemic therapy efficacy, Charlson comorbidity index and cerebral metastasis status appeared to be important indexes for choice of locoregional therapy in different individuals.

For locoregional therapy group, statistical differences were observed in all subgroups stratified by the factors that were significant in univariate analysis except in the subgroups of stable disease, Charlson comorbidity index ≥3 and cerebral metastasis. Therefore, systemic therapy efficacy, Charlson comorbidity index and cerebral metastasis status appeared to be important indexes for choice of locoregional therapy in different individuals.

    Acute type A aortic dissection (AcA-AoD) is a surgical emergency associated with very high morbidity and mortality. Unfortunately, the early outcome of emergency surgical repair has not improved substantially over the last 20 years. Many of the same debates occur repeatedly regarding operative extent and optimal conduct of the operation. The question remains: are patients suffering from too large an operation or too small? The pendulum favoring routine aortic valve resuspension, when feasible, has swung towards frequent aortic root replacement. This already aggressive approach is now being challenged with the even more extensive valve-sparing aortic root replacement (V-SARR) in selected patients. Distally, open replacement of most of the transverse arch is best in most patients. The need for late aortic re-intervention has not been shown to be affected by more extensive distal operative procedures, but the contemporary enthusiasm for a distal frozen elephant trunk (FET) only seems to build. It must be remembered that the first and foremost goal of the operation is to have an operative survivor; additional measures to reduce late morbidity are secondary aspirations. With increasing experience, true contraindications to emergency surgical operation have dwindled, but patients with advanced age, multiple comorbidities, and major neurological deficits do not fare well. The endovascular revolution, moreover, has spawned innovative options for modern practice, including ascending stent graft and adaptations of the old flap fenestration technique. Despite the increasingly complex operations and ever expanding therapies, this life-threatening disease remains a stubborn challenge for all cardiovascular surgeons. Development of specialized thoracic aortic teams and regionalization of care for patients with AcA-AoD offers the most promise to improve overall results. PMID:27563541

    Vascular pythiosis, a vascular infectious disease in hemoglobinopathy patients, caused by Pythium insidiosum, has an endemic area in tropical and subtropical countries. According to literature review, suprainguinal vascular pythiosis leads to 100% of mortality. The authors report a 35-year-old thalassemic patient who presented with a right inflammatory pulsatile groin mass and right limb ischemia. The computerized tomography angiography indicated a false aneurysm at the right external iliac artery and thrombosed entire right leg arteries. The management comprised antifungal agent, immunotherapy, and surgical removal of all infected arteries (high up to the right common iliac artery and above-knee amputation). The patient was found in a good condition at 36 months after the follow-up period. PMID:24911809

    In our Division of Cardiothoracic Surgery between 1970 and 1982, 110 patients (88 males and 22 females) had coronary artery bypass grafts (CABG) performed for unstable angina pectoris after acute transmural myocardial infarction. Fifty-one patients (mean age 59 years) had CABG within 2 weeks of myocardial infarction (Group 1); and 59 patients (mean age 56 years) (p = NS) within 6 weeks of myocardial infarction (Group 2). The incidence of preoperative arrhythmias, left ventricular ejection fraction, end-diastolic pressure, and the number of vessels diseased were similar in Groups 1 and 2. The incidence of cardiogenic shock was higher in Group 1 (16/51, 31% vs 2/59, 3% [p < 0.001]). This was also the case with the use of the intraaortic balloon (32/51, 63% vs 12/59, 20% [p < 0.001]), and the need for emergency operation (29/51, 57% vs 4/59, 7% [p < 0.001]). The mean number of grafts was 2.8 in Group 1 and 3.0 in Group 2 (p = NS). Operative mortality was 20% (10/51) in Group 1 and 7% (4/59) in Group 2 (p < 0.01). Excluding patients in cardiogenic shock, operative mortality was 0% (0/35) in Group 1 and 5% (3/57) in Group 2 (p = NS). Incidences of late death, recurrent angina, and permanent disability were similar during mean follow-up times of 3.2 years in Group 1 and 4.1 years in Group 2. Actuarial probability of survival was 96% at 1 year and 83% at 5 years. Myocardial revascularization early after transmural myocardial infarction has a low risk, especially in the absence of cardiogenic shock. These results justify an aggressive approach to unstable angina, including patients within 2 weeks of transmural infarction. PMID:15226989

CONCLUSIONS: GH administration accelerated protein gain in stable adult patients receiving aggressive nutritional therapy without a significant increase in body fat or a disproportionate expansion of ECW.

    Gastric cancer is one of the most common digestive malignant tumors. More and more elderly gastric cancer patients are diagnosed and need to undergo surgical treatment as the population ages. Since the elderly patients decrease in organ function and increase in internal diseases, the tolerance to anesthesia and surgery is poor. As a result, the incidence of surgical and postoperative complications is obviously higher. Complications can be divided into surgical complications and non-surgical related complications. Surgical complications consist mainly of hemorrhage, anastomotic leakage, anastomotic dehiscence and intestinal obstruction, while non-surgical related complications include deep venous thrombosis, pulmonary infection, anesthesia-related complication, abdominal infection, urinary infection, incision infection, poor wound healing, gastroparesis, gastroesophageal reflux disease, dumping syndrome and so on. Hence, we should consider more about the elderly patients' physical condition instead of the extent of radical operation. To reduce complications, we should evaluate the organ function and take an active role in underlying diseases before operation. Meanwhile, high quality nursing, powerful analgesia, anti-inflammation, keeping water electrolyte balance and nutrition support are also required postoperatively. Moreover, laparoscopic surgery and enhanced recovery after surgery (ERAS) can reduce the postoperative complications in elderly patients with gastric cancer as well. Further prospective randomized controlled trials about elderly gastric cancer should be carried out in the future, which can provide advanced evidences for treatment. PMID:27215514

    Objective Agitation and aggression are among the most frequent and disruptive behavioral complications of dementia that contribute to increased cost of care, hospitalization, caregiver burden, and risk of premature institutionalization. This current study examined the safety and efficacy of electroconvulsive therapy (ECT) as a treatment for behavioral disturbances in dementia. We hypothesized that ECT would result in reduced agitated and aggressive behaviors between baseline and discharge. Methods Twenty-three participants admitted to McLean Hospital (Belmont, MA) and Pine Rest Christian Mental Health Services (Grand Rapids, MI), with a diagnosis of dementia who were referred for ECT to treat agitation and/or aggression, were enrolled in the study. We administered the Cohen-Mansfield Agitation Inventory (CMAI)-short form, Neuropsychiatric Inventory (NPI)-Nursing Home Version, Cornell Scale for Depression in Dementia (CSDD), and the Clinical Global Impression Scale (CGI) at baseline, during, and after the ECT course. Results Regression analyses revealed a significant decrease from baseline to discharge on the CMAI (F(4, 8) =13.3; p=0.006) and NPI (F(4, 31)= 14.6; p<0.001). There was no statistically significant change in scores on the CSDD. The CGI scores on average changed from a rating of “markedly agitated/aggressive” at baseline to “borderline agitated/aggressive” at discharge. Treatment with ECT was well tolerated by most participants; discontinuation of ECT occurred for two participants due to recurrence of agitation and for three participants due to adverse events. Conclusions ECT may be a safe treatment option to reduce symptoms of agitation and aggression in patients with dementia whose behaviors are refractory to medication management. PMID:24838521

    Background Aggressive periodontitis (AgP) is a severe form of periodontal diseases with rapid destruction of the supporting bone around teeth. The efficacy of PDT in suppressing periodontal pathogens may be crucial in adopting new protocols for the treatment of AgP. Thus, the aim of this systematic review was to investigate the possible role of PDT in the treatment of AgP as an adjunctive therapy or monotherapy. Material and Methods A systematic search of the literature was performed. Additionally, the references from all the selected full-text studies were searched for relevant articles. Two reviewers screened independently titles and abstracts or full text copies. Quality assessment of all the included studies was held. Results Initial screening of electronic databases yielded 418 potentially relevant publications. After screening of the titles and full-text examination, five studies were included in the systematic review. Four publications evaluated the effects of PDT adjunctive to SRP in patients with AgP: two of them compared the clinical outcomes of SRP and PDT with a control group that received therapy with SRP and antibiotics (metronidazole and amoxicillin); two publications included SRP and PDT in the test group, and SRP alone in the control group. In one study, PDT was tested as a monotherapy compared with SRP alone. Conclusions Within the limitations of this review, PDT may exhibit a beneficial role in the therapy of aggressive periodontitis after repeated applications. In the future, more methodologically sound, long-term randomized clinical trials are needed to be conducted. Key words:Photodynamic therapy, periodontitis, systematic review. PMID:26595837

    Maintenance therapy in patients with aggressive malignant lymphoma using biological modifiers remains uncertain. We conducted a controlled clinical trial to evaluate the efficacy and toxicity of interferon-alpha 2b, cyclophosphamide, and prednisone as maintenance therapy in patients with aggressive diffuse large B cell lymphomas in complete remission after aggressive chemotherapy. In an intent-to-treat analysis, 169 patients were eligible for this study; the end points were event-free survival (EFS) and overall survival (OS). With a median follow-up of 49.3 months, no statistical differences were observed and actuarial curves at 5 years showed that EFS was 71% (95% confidence interval [CI], 63-79%) for patients who received maintenance compared to 63% (95% CI, 59-71%) for patients in control group (p = 0.05). No statistical differences were observed in OS between maintenance arm: 84% (95% CI, 78-89%) and control group 83% (95% CI, 77-88%) in control group (p = 0.2). All patients received the maintenance therapy as planned and in time, thus dose intensity was considered 1.0 in all cases. Acute toxicity was mild, and no delay or suspension of treatment was necessary. Late toxicity was not evident until now. We conclude that use of maintenance therapy combining interferon-alpha 2b, cyclophosphamide, and prednisone is not useful in patients with aggressive lymphoma if they had been treated with aggressive combined chemotherapy.

    Primary Testicular Lymphoma (PTL) is a rare intermediate to high grade tumour, diffuse large cell being the most common type. Unlike nodal Diffuse Large B-Cell Lymphoma (DLBCL), testicular DLBCL has a less aggressive course and better prognosis. Metastasis is uncommon in testicular DLBCL. Commonly involved sites are contralateral testes, Waldeyer’s ring, skin, lung, Central Nervous System (CNS) and prostate, however the kidneys, liver, bone marrow, pleura and bones are more rarely involved. We report a case of testicular DLBCL which has metastasized to skin and bone marrow with an aggressive clinical course in a year, in-spite of combined modality of therapy given to the patient. Bone marrow infiltration is common and well documented with nodal DLBCL, however there is no published literature for simultaneous bone marrow and skin infiltration in testicular DLBCL till date. Other large studies done in the west have shown that distinct metastasis is usually common but the median progression-free survival is usually in years. This case stresses on shorter period of progression after standard treatment protocol in this part of the world, thus highlighting the need for other extensive studies to define specific treatment protocol for testicular DLBCL.

    Mantle cell lymphoma (MCL) is a heterogeneous disease, and it has been well-established over the last decade that a subset of patients can have indolent presentation. It is therefore important to adopt a risk-stratified approach in order to minimize unnecessary toxicities while maximizing survival and quality of life in selected MCL patients. This review provides an up-to-date assessment of clinical and pathologic entities associated with indolent disease course and delineates available biomarkers with predictive significance. Initial treatment decisions should be guided by risk assessment to discern patients who might do well with deferred therapy, from those who would require treatment with non-aggressive first-line regimens.

    Peritonitis complicating diverticular disease may be treated by sigmoid resection (with or without primary anastomosis) or by a conservative surgical approach, either laparoscopically or by open surgery. The choice depends on the severity of the peritonitis (Hinchey), the patient's conditions (ASA) and the surgeon's experience. Sigmoid resection with primary anastomosis has a lower morbidity and mortality vs Hartmann's procedure. After the introduction of laparoscopy in colorectal surgery, exploratory laparoscopy combined with drainage has been proposed to treat acute episodes, followed by laparoscopic resection. Since 1982, over 1000 patients have been operated on for colorectal disease: 119 for complicated diverticulitis, 55 of which complicated by peritonitis. In the latter, we performed conservative surgery (25 patients) and resection (30 patients) laparoscopically or by open surgery. Our results show a higher morbidity and mortality for the Hartmann procedure vs sigmoid resection with primary anastomosis and a lower specific morbidity in patients undergoing laparoscopic exploration and drainage. Moreover, there was a low percentage (52%) of re-canalisations with the Hartmann procedure, with a morbidity of 32% associated with this procedure. In conclusion, we believe that a conservative laparoscopic surgical approach may be advocated in selected cases (Hinchey II and III without clear perforation), followed by laparoscopic sigmoidectomy, resection with primary anastomosis in Hinchey I or in cases of evident perforation with purulent or faecal peritonitis (possibly combined with a stoma), reserving the Hartmann procedure for compromised patients.

    A transsexual patient has the constant and persistent conviction that he or she belongs to the opposite sex, thus creating a deeply seated gender identity conflict. With psychotherapy being unsuccessful, it has been proven that in carefully selected patients, gender reassignment or adjusting the body to the mind (both with hormones and surgery) is the best way to normalize their lives. Optimal treatment of these patients requires the multidisciplinary approach of a gender team with the input of several specialties. Such a team consists of a nucleus of physicians who sees the patient more frequently: the psychiatrist, the endocrinologist, the plastic surgeon, the gynecologist and the urologist and a more peripheral group that sees the patients more incidentally: the psychologist, the otorhinolaryngologist, the dermatologist, the speech therapist, the lawyer, the nurse and the social worker. Between 1987 and 1999, a total of 71 male-to-female (MTF) and 54 female-to-male transsexuals have undergone gender confirming surgery in our hospital. This article gives a review and an update on the different surgical procedures as well as on the outcome in our patient population. The results in this series of patients clearly demonstrate that a close cooperation of the different surgical specialties, within our multidisciplinary gender team, is the key to success in treating transsexual patients.

    Context Despite reported success, surgery for pharmacoresistant seizures is often seen as a last resort. Patients are typically referred for surgery after 20 years of seizures, often too late to avoid significant disability and premature death. Objective We sought to determine whether surgery soon after failure of 2 antiepileptic drug (AED) trials is superior to continued medical management in controlling seizures and improving quality of life (QOL). Design, Setting, and Participants The Early Randomized Surgical Epilepsy Trial (ERSET) is a multicenter, controlled, parallel-group clinical trial performed at 16 US epilepsy surgery centers. The 38 participants (18 men and 20 women; aged ≥ 12 years) had mesial temporal lobe epilepsy (MTLE) and disabling seizues for no more than 2 consecutive years following adequate trials of 2 brand-name AEDs. Eligibility for anteromesial temporal resection (AMTR) was based on a standardized presurgical evaluation protocol. Participants were randomized to continued AED treatment or AMTR 2003–2007, and observed for 2 years. Planned enrollment was 200, but the trial was halted prematurely due to slow accrual. Intervention Receipt of continued AED treatment (n=23) or a standardized AMTR plus AED treatment (n = 15). In the medical group, 7 participants underwent AMTR prior to the end of follow-up and 1 participant in the surgical group never received surgery. Main Outcome Measures The primary outcome variable was freedom from disabling seizures during year 2 of follow-up. Secondary outcome variables were health-related QOL (measured primarily by the 2-year change in the Quality of Life in Epilepsy 89 [QOLIE-89] overall T-score), cognitive function, and social adaptation. Results Zero of 23 participants in the medical group and 11 of 15 in the surgical group were seizure free during year 2 of follow-up (odds ratio=∞; 95% CI, 11.8 to ∞;P <.001).

    Medullary thyroid carcinoma (MTC) is a rare form of malignancy, having an intermediate prognosis. Controversies exist regarding the best surgical approach. The aim of the study was to analyze the outcome in a group of patients with MTC, diagnosed and followed up in a single care center. We performed a retrospective analysis of all the patients diagnosed with MTC in the Department of Endocrinology from the County Emergency Hospital Timisoara between 1992 and 2012. The study group included 19 patients, 6 men (31.6 %), mean age 41.2 ± 12.5 years (20-72 years). The preoperative diagnosis was based on the protocol for nodular thyroid disease. Total or near-total thyroidectomy was performed in 10 out of 16 patients who could be operated. Postoperative follow-up included repeated measurements of serum calcitonin and imaging investigations. Nine out of the total of 19 (47.3 %) patients had hereditary forms of MTC. Most of the cases (84.2 %) were submitted to surgery. The median duration of follow-up was 84 months. The pTNM staging indicated that the majority of the patients with hereditary MTC were diagnosed in an earlier stage. Disease remission was achieved in 7 cases (43.8 %). Four patients, all with sporadic forms, died. Survival rates at 1, 5 and 10 years were significantly higher (p = 0.048) in patients with hereditary MTC. An early diagnosis of MTC allows a better surgical approach and an improved survival rate. We support the general recommendation that modified radical neck dissection is not necessary for all the patients with MTC. PMID:27574350

    Background: In the present era, delinquency in children and adolescents is undoubtedly a difficult and upsetting issue attracting the attention of many experts such as psychologists, sociologists, and criminologists. These experts often try to answer why a number of children and adolescents engage in various crimes such as aggressive and anti-social crimes. They also try to find out how these crimes can be prevented. Objectives: The present study investigates the effectiveness of mindfulness-based cognitive therapy training (MBCT) in reducing aggression in a juvenile correction and rehabilitation center of Zahedan province during years 1991 to 1992. Materials and Methods: This experimental study included an experimental and a control group with a pretest, posttest, and follow-up approach. The Buss and Perry aggression questionnaire (1992) was used for data collection. The sample group included 22 (10 experimental and 12 control groups) adolescent males in a juvenile correction and rehabilitation center of Zahedan province who were selected through a census method. Using a matching method based on the pre-test scores of the aggression questionnaire, they were then divided into two equivalent categories and were randomly assigned to the two groups. Mindfulness-based cognitive training took the group training in 8 sessions administered on experimental group. The follow-up test was conducted two weeks after the end of the posttest sessions. The results were analyzed using ANCOVA. Results: The results of ANCOVA showed that mindfulness-based cognitive training could significantly reduce aggression during posttest and follow-up test phases in the experimental group, compared to the control group (P < 0.01). Moreover, the results indicated the effectiveness of this method in significantly reducing anger, physical aggression, and hostility during posttest and follow-up test phases (P < 0.05). However, no significant reduction was observed in the verbal aggression subscale

    Primary intestinal lymphangiectasia (PIL) is a protein-losing, exsudative gastroenteropathy causing lymphatic obstruction. Diagnosis depends on clinical examination and histological findings. Conservative treatment modalities include a low-fat diet and enteral nutritional therapy in order to reduce enteric protein loss and to improve fat metabolism. Other treatment options consist of administration of antiplasmin or octreotide to lower lymph flow and secretion. We report on a 58-year-old patient who underwent exploratory laparotomy due to a worsening physical status, recurrent chylaskos and leg oedema under conservative dietary therapy. Intraoperative findings showed a typical PIL of the jejunum about 20 cm distal to the Treitz's ligament. Histological examinations confirmed this diagnosis. One year after segmental small bowel resection (105 cm) with end-to-end anastomosis the patient is healthy, free of symptoms, has gained weight and his serum protein level has increased. Intraabdominal ascites and leg oedema have not reoccurred since. PMID:23229460

    We have performed high dose photoradiation therapy in patients with cerebral tumors. Twenty-seven patients had gliomas, two had metastatic cancer of the brain, one had malignant meningioma. Hematoporphyrin derivative was administered intravenously. All patients underwent a craniotomy with a radical or partial excision of the tumor. There was no evidence of increased cerebral edema and other toxicity from the therapy, and all patients were discharged from the hospital within 15 days after surgery. On the basis of animal experiments our institute started using photodynamic therapy (PDT) as an adjuvant measure to the operative therapy in 30 cases of cerebral tumors. Ten of these patients were excluded from this group because of the short postoperative following time. Here, the details of our experiences are presented as follows: 106 of C6 type glioma cell strain were implanted into the frontal lobe of a Chinese hamster. Fourteen days later intracranial gliomas developed, which were larger than 4 mm in diameter, HpD in a dosage of 4 mg/kg was injected into the tail vein of the animals. The fluorescence was seen 5 minutes later. The diagnostic laser used was He-Ca (Hc-type 15A, made at Shanghai Laser Institute) with a wavelength of 441.6 nm, power of 30 mw. The fluorescence reached its peak point 24 hours later, and the normal tissue can be identified by the lack of fluorescence. Then, the tumor tissue was further radiated with an Ar laser (made in Nanjing Electronic Factory, type 360), pumped dye-laser (made in Changchun Optic Machinery Institute, type 901) with a wavelength of 630 nm, and an energy density of more than 200 Joules/cm2, which might get the tumor cells destroyed selectively. The effect of photoradiation may reach as deep as 4 - 7 mm into the brain tissue without cerebral edema or necrosis.

    A few years ago surgical resection was the only treatment modality for primary and metastatic liver tumors. However, most of the liver tumors are diagnosed at advanced stage and are unresectable. Criteria for unresectability are: uncontrolled extrahepatic disease, extensive intrahepatic tumor growth, insufficient remnant liver volume and severe co-morbid disease. Several therapeutic strategies have been developed to deal with primarily unresectable tumors. A downstaging ("downsizing") of hepatocellular carcinoma (HCC) can be reached by transarterial chemoembolisation (TACE) or local tumor ablation using ethanol injection, cryosurgery and radiofrequency. Preoperative unilateral portal vein embolization resulting in hypertrophy of the remnant liver volume permits to resect some patients with former unresectable liver tumors. Furthermore, liver transplantation is an option for patients with early stage HCC and liver cirrhosis. Preoperative downstaging of colorectal metastases can be achieved with neoadjuvant chemotherapy, whereas TACE, ethanol injection and liver transplantation are no established options for these patients. So far, there are no standardized guidelines for the treatment of patients with unresectable primary or metastatic liver tumors. In this review we aim to describe the different approaches suggested in the literature and to present our algorithms for the management of patients with liver tumors. PMID:16138770

    Engineered stem cell (SC)-based therapy holds enormous promise for treating the incurable brain cancer glioblastoma (GBM). Retaining the cytotoxic SCs in the surgical cavity after GBM resection is one of the greatest challenges to this approach. Here, we describe a biocompatible electrospun nanofibrous scaffold (bENS) implant capable of delivering and retaining tumor-homing cytotoxic stem cells that suppress recurrence of post-surgical GBM. As a new approach to GBM therapy, we created poly(l-lactic acid) (PLA) bENS bearing drug-releasing human mesenchymal stem cells (hMSCs). We discovered that bENS-based implant increased hMSC retention in the surgical cavity 5-fold and prolonged persistence 3-fold compared to standard direct injection using our mouse model of GBM surgical resection/recurrence. Time-lapse imaging showed cytotoxic hMSC/bENS treatment killed co-cultured human GBM cells, and allowed hMSCs to rapidly migrate off the scaffolds as they homed to GBMs. In vivo, bENS loaded with hMSCs releasing the anti-tumor protein TRAIL (bENS(sTR)) reduced the volume of established GBM xenografts 3-fold. Mimicking clinical GBM patient therapy, lining the post-operative GBM surgical cavity with bENS(sTR) implants inhibited the re-growth of residual GBM foci 2.3-fold and prolonged post-surgical median survival from 13.5 to 31 days in mice. These results suggest that nanofibrous-based SC therapies could be an innovative new approach to improve the outcomes of patients suffering from terminal brain cancer. PMID:27016620

    Unilateral elevation of the diaphragm may be due to various causes and requires further elucidation when the aetiology is unknown. Elevation of the diaphragm is often caused by diaphragmatic paralysis, either due to damage to the phrenic nerve or to the phrenic muscle. Patients typically complain of increased respiratory distress when lying down, bending or swimming. Basic diagnostic testing consists of a chest X-ray, as well as spirometry and computer tomography of the neck and chest. In many cases, no cause can be identified for the diaphragmatic paralysis. In symptomatic patients, diaphragm plication leads to fixation and thus to a reduction in the paradoxal respiratory movement of the paralysed diaphragm. In a large majority of studies, this results in significant and lasting improvement in vital capacity and respiratory distress. Spontaneous recovery of diaphragm paralysis is possible, even after several months, so a waiting period of at least 6 months should elapse before diaphragmatic plication is performed, if the clinical situation allows. The procedure can be performed minimally invasively, with low morbidity and mortality. When cutting the phrenic nerve, a nerve suture is recommended, if possible, or otherwise diaphragm plication during the procedure, especially in the case of pneumonectomy. This review provides an overview of the causes, pathophysiology, symptoms, diagnosis, therapy and results of diaphragmatic plication in acquired, unilateral diaphragmatic paralysis in adults, and suggests an algorithm for diagnostic testing and therapy.

    Vacuum-assisted closure (VAC) therapy is a new emerging non-invasive system in wound care, which speeds up wound healing by causing vacuum, improving tissue perfusion and suctioning the exudates, and facilitating the removal of bacteria from the wound. The application of sub-atmospheric pressure on the lesions seems to alter the cytoskeleton of the cells on the wound bed, triggering a cascade of intracellular signals that increase the rate of cell division and subsequent formation of granulation tissue. The aim of this study is to analyse the results of VAC therapy used as an adjuvant therapy for the treatment of foot wounds in patients affected by critical limb ischaemia (CLI) (Rutherford 6 class) after distal surgical revascularisation, to promote and accelerate the healing of ulcers. Twenty-nine patients (20 males, 9 females; mean age 68·4) affected by CLI of Rutherford 6 class, after surgical revascularisation of the lower limb, underwent VAC therapy in order to speed up wound healing. Complete wound healing was achieved in 19 patients (65·51%), in an average period of 45·4 ± 25·6 days. VAC therapy is a valid aid, after surgical revascularisation, to achieve rapid healing of foot lesions in patients with CLI. PMID:24872149

    To assess the efficacy and toxicity of interferon alfa 2b (IFN) as maintenance therapy in patients with malignant lymphoma on complete response after conventional chemotherapy we start a randomized clinical trial. One hundred and seventy patients were randomized to received either IFN 5.0 MU three time at week by one year or no further treatment, as control group. At a median follow-up of 9.0 years (range 4.3 to 11 years) median freedom from relapse (FFR) has not been reached in patients who received IFN, it is statistically significant to patients in control group with a median FFR of 60 months (p <.001). Actuarial curves show that at 10-years, 58 patients (66%, 95% confidence interval (CI) 53% to 79%) remain in first remission, statistical different to control group 33 patients (40%, 95% Cl: 33% to 57%) (p <.001). Event free survival (EFS) shown that a 10-years 63 patients (71%, 95% CI: 59% to 81%) are alive free of disease in the IFN arm compared to only 38 patients (45%, 95% CI: 37% to 57%) in the control group (p <.001). Toxicity was mild, 81 patients received the planned doses of IFN on time and 6 patients had transitory delay secondary to hematological toxicity (grade 1 or 2) and completed the treatment on 13 months. No late side effects has been observed. After a long term follow-up we confirm that IFN used as maintenance therapy improves outcome in patients with aggressive malignant lymphoma who were in complete remission after conventional chemotherapy without excessive toxicity. We feld that IFN will be consider in controlled clinical trials to define the role of this therapeutic option. PMID:27414082

    As ErbB signaling is a determinant of prolactin synthesis, role of ErbB receptors was tested for prolactinoma outcomes and therapy. The objective of this study was to characterize ErbB receptor expression in prolactinomas and then perform a pilot study treating resistant prolactinomas with a targeted tyrosine kinase inhibitor (TKI). Retrospective analysis of prolactinomas and pilot study for dopamine agonist resistant prolactinomas in tertiary referral center. We performed immunofluorescent staining of a tissue array of 29 resected prolactinoma tissues for EGFR, ErbB2, ErbB3, and ErbB4 correlated with clinical features. Two patients with aggressive resistant prolactinomas enrolled and completed trial. They received lapatinib 1,250 mg daily for 6 months with tumor and hormone assessments. Main outcome measures were positive tumor staining of respective ErbB receptors, therapeutic reduction of prolactin levels and tumor shrinkage. Treated PRL levels and tumor volumes were suppressed in both subjects treated with TKI. EGFR expression was positive in 82 % of adenomas, ErbB2 in 92 %, ErbB3 in 25 %, and ErbB4 in 71 %, with ErbB2 score > EGFR > ErbB4 > ErbB3. Higher ErbB3 expression was associated with optic chiasm compression (p = 0.03), suprasellar extension (p = 0.04), and carotid artery encasement (p = 0.01). Higher DA response rates were observed in tumors with higher ErbB3 expression. Prolactinoma expression of specific ErbB receptors is associated with tumor invasion, symptoms, and response to dopamine agonists. Targeting ErbB receptors may be effective therapy in patients with resistant prolactinomas. PMID:24287797

    Background Pterygium is a proliferative disease with hyperplastic growth of corneoconjunctival fibro vascular tissue onto the cornea. Surgical therapy can be used to successfully manage pterygia; however, recurrence remains a problem. To reduce recurrence, surgical management may include autoconjunctival grafting, lamellar keratoplasty, amniotic membrane transplantation, and intraoperative antimetabolites application. Purpose To assess the safety and the efficacy of intraoperative mitomycin C (MMC) and 5-fluorouracil (5-FU) application in preventing recurrence of pterygium after excision. Patients and methods The study design is a prospective, randomized clinical trial. A total of 50 patients with bilateral pterygium were recruited for the study. The first group of patients (25) underwent surgical excision of the pterygium with bare sclera in one eye and MMC was applied as adjunctive therapy for the other eye. In the second group 5-FU was used instead of MMC. Recurrences and postoperative complications were measured in the two groups. The mean follow up period of the patients was 18.8 months. Chi square test, odds ratio, and frequency distribution were used to determine significance levels; P-values <0.05 were considered statistically significant. Results In group 1 the recurrence rate was 8% for the MMC treated eyes and 32% for their fellow eyes (P = 0.03). In group 2 the rate was 18% for the 5-FU treated eyes and 34% for their fellow eyes (P = 0.07). No serious complications were recorded in either group. Conclusion Both MMC and 5-FU reduce the recurrence rate of pterygium after simple surgical excision; statistically, the effect of the former was significant, but insignificant for the latter. Both antimetabolites were safe during the whole study period, but 5-FU recurrent cases showed cosmetically unacceptable appearances with excessive vascularization. MMC, but not 5-FU, is recommended as an adjunctive therapy to prevent recurrence of pterygium after surgical

    Cardiac magnetic resonance (CMR) imaging may allow more appropriate selection of patients for cardiac device implantation and/or cardiac surgery. In this prospective observational study we evaluated the impact of CMR imaging on cardiac device and surgical therapy. All CMR examinations performed in a single centre over a 2 year period were prospectively recorded in a dedicated database under 4 clinical pathways [cardiomyopathy, viability, tumour/mass and arrythmogenic right ventricular cardiomyopathy (ARVC)]. Baseline data entered included planned cardiac device implantation and/or cardiac surgical intervention. Patients were contacted 6 months following CMR to evaluate the impact of CMR on planned therapy. Cost savings due to CMR were calculated as the number of surgical or device procedures averted following CMR scanning multiplied by their respective cost weights. Of 732 CMR examinations performed, the clinical pathway was cardiomyopathy in 488 (67 %), ARVC in 118 (16 %), viability in 92 (12 %) and tumour/mass in 34 (5 %). Six month follow-up was available in 666/732 patients. Following CMR, 56/150 (37 %) of patients with an initial plan for device implantation or cardiac surgery, did not undergo the planned intervention (P < 0.001, one-sample exact binomial test). Of 516 patients without an initial device or surgical plan, 33 (6 %) CMR resulted in device implantation or cardiac surgery (P < 0.001, Chi squared). Overall, the estimated saving due to CMR-guided management changes was AUD$737,270. CMR has a significant impact on patient management and offers potential cost savings with respect to selection of device and surgical therapy for cardiac disease. PMID:23592405

    The aim of this systematic review was to investigate whether the use of antimicrobial photodynamic therapy (aPDT) as an adjuvant to scaling and root planning (SRP) yields better results than SRP alone or associated with systemic antibiotics in the treatment of aggressive periodontitis (AgP). A meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statements and Cochrane Collaboration recommendations. The search for relevant studies (earliest record to January 2015) was carried out in seven databases, followed by a manual search. Methodological quality assessment of the studies selected was based on an analysis of the risk of bias. At each time point of follow-up, the existence of significant differences (p < 0.05) in clinical attachment level (CAL) gain and probing depth (PD) reduction (primary outcomes) between groups was assessed with RevMan software 5.0. Heterogeneity between studies was assessed by the Higgin test (I (2)). Four randomized controlled trials (RCTs) satisfied the eligibility criteria of this review. Only one study was found to have a low risk of bias. There were no significant differences in PD reduction (mean difference 0.33, 95 % confidence interval -0.32 to 0.98, p = 0.32) and CAL gain (mean difference 0.20, 95 % confidence interval -0.41 to 0.81, p = 0.53) between the test and control interventions. At present, therefore, when compared to SRP alone or associated with systemic antibiotics, the evidence suggests that the association of aPDT + SRP is of no additional benefit in the nonsurgical treatment of AgP.

    Breast cancer is the commonest cancer in the UK. Advances in breast cancer treatment means that the sequelae of treatment are affecting more women and for a longer duration. Lymphoedema is one such sequela, with wide-ranging implications, from serious functional and psychological effects at the individual level to wider economic burdens to society. Breast cancer-related lymphoedema is principally managed by conservative therapy comprising compression garments and manual decongestive massage. This approach is effective for early stages of lymphoedema, but it is not curative and the effectiveness depends on patient compliance. Early surgical approaches were ablative, gave significant morbidity and hence, reserved for the most severe cases of refractory lymphoedema. However, recent non-ablative reconstructive surgical approaches have seen a revival of interest in the prevention or surgical management of breast cancer-related lymphoedema. This review examines the modern surgical techniques for the treatment of breast cancer-related lymphoedema. Liposuction reduces the volume and symptoms of lymphedema, but requires continual compressive therapy to avoid recurrence. Lymphatic reconstruction or bypass techniques including lymph node transfer (inguinal nodes are transferred to the affected limb), lymphatico-lymphatic bypass (lymphatics bypass the axilla using a lymph vessel graft reconstructing lymphatic flow from arm to neck) and lymphaticovenous anastomoses (lymphatics in the arm are joined to the venous system aiding lymph drainage) show promise in reducing lymphedema significantly. Further research is required, including into the role of primary lymphaticovenous anastomoses in the prevention of lymphedema at the time of axillary dissection. PMID:25747119

    Aggressive periodontitis (AgP) is an inflammatory disease characterized by rapid attachment loss and bone destruction. This case report presents the 10-year results in a subject with generalized AgP treated by a regenerative periodontal therapeutic approach and the adjunctive use of antibiotics, following a systematic maintenance periodontal therapy. The use of enamel matrix derivatives (EMD) and adjunctive antibiotic therapy to treat AgP yielded improvements in clinical parameters and radiographic bony fill. This combined therapeutic approach following a systematic supportive periodontal therapy supports the long-term maintenance of teeth with previous advanced periodontal defects, demonstrating successful stability after 10-years follow-up. Clinical Relevance: The combined treatment protocol using EMD plus adjunctive antibiotic therapy, associated with a systematic supportive periodontal therapy, benefits the long-term maintenance of teeth with previous advanced periodontal defects in subjects presenting AgP, supporting this approach as an alternative in the treatment of AgP.

    OBJECTIVE This study aims to describe the frequency of use and reported effectiveness of endoscopic and surgical therapies in patients with CP treated at US referral centers. METHODS Five hundred fifteen patients were enrolled prospectively in the North American Pancreatitis II Study 2, where patients and treating physicians reported previous therapeutic interventions and their perceived effectiveness. We evaluated the frequency and effectiveness of endoscopic (biliary or pancreatic sphincterotomy, biliary or pancreatic stent placement) and surgical (pancreatic cyst removal, pancreatic drainage procedure, pancreatic resection, surgical sphincterotomy) therapies. RESULTS Biliary and/or pancreatic sphincterotomy (42%) were the most commonly attempted endoscopic procedure (biliary stent, 14%; pancreatic stent, 36%; P<0.001). Endoscopic procedures were equally effective (biliary sphincterotomy, 40.0%; biliary stent, 40.8%; pancreatic stent, 47.0%; P=0.34). On multivariable analysis, the presence of abdominal pain (odds ratio, 1.82; 95% 95% confidence interval, 1.15–2.88) predicted endoscopy, whereas exocrine insufficiency (odds ratio, 0.63; 95% confidence interval 0.42–0.94) deterred endoscopy. Surgical therapies were attempted equally (cyst removal, 7%; drainage procedure, 10%; resection procedure, 12%) except for surgical sphincteroplasty (4%; P<0.001). Surgical sphincteroplasty was the least effective therapy (46%; P<0.001) versus cyst removal (76% drainage [71%] and resection [73%]). CONCLUSIONS Although surgical therapies were performed less frequently than endoscopic therapies, they were more often reported to be effective. PMID:24717802

    Patients with desmoplastic small round cell tumors (DSRCTs) have an extremely poor outcome despite the use of aggressive therapy. The current study presents the case of 16-year-old male with metastatic DSRCT, in which multimodal therapy, including intensive chemotherapies using frequent autologous stem cell support, gross resection of primary and metastatic lesions, and whole abdominopelvic intensity-modulated radiation therapy, was administered. Subsequent to these treatments, there was no evidence of active disease. However, cerebellar and pineal body lesions, and bone metastasis to the left humerus were detected 1 year and 2 months after the initial diagnosis. Combination chemotherapy with irinotecan and temozolomide was initially effective against the central nervous system (CNS) metastatic lesions; however, the patient succumbed due to progressive CNS disease after seven courses of combination chemotherapy. Additional studies are required to accumulate information regarding CNS recurrence of DSRCT. PMID:26870296

    This is a compact visual description of a combination of surgical technique and device for the delivery of (gene and cell) therapies into the spinal cord. While the technique is demonstrated in the animal, the procedure is FDA-approved and currently being used for stem cell transplantation into the spinal cords of patients with ALS. While the FDA has recognized proof-of-principle data on therapeutic efficacy in highly characterized rodent models, the use of large animals is considered critical for validating the combination of a surgical procedure, a device, and the safety of a final therapy for human use. The size, anatomy, and general vulnerability of the spine and spinal cord of the swine are recognized to better model the human. Moreover, the surgical process of exposing and manipulating the spinal cord as well as closing the wound in the pig is virtually indistinguishable from the human. We believe that the healthy pig model represents a critical first step in the study of procedural safety. PMID:23242422

    We report a case of a 48-year-old Indian male who presented with swelling and firmness in his left upper part of the abdomen of one month duration with anorexia and weight loss. Initial examination revealed an intra abdominal mass of around 16.8x11.0x24.5cm with minimal left sided pleural effusion. A biopsy from the mass confirmed the diagnosis of gastrointestinal stromal tumour (GISTs) as supported by immmunohistochemistry results which showed strong positivity for c-kit while stains for smooth muscle actin, desmin, myoglobin, S100 Protein and cytokerstin remained negative. The patient was not suitable for surgical intervention in view of advanced tumor, and Imatinib Mesylate 400mg daily was started with the aim of making the tumor operable. Such therapy lasted for twenty months and was tolerated well by the patient. It then resulted in gradual tumor regression, following which the patient underwent successful tumor resection. Post surgical resection patient had no radiological evidence of intra abdominal tumor but mild left sided pleural effusion with left lower lobe atelectasis. The patient had uneventful post operative recovery and he is currently on Imatinib mesylate and tolerating treatment well with mild skin rash. The experience with preoperative imatinib on surgical resection rates and post operative outcomes is limited especially with primary locally advanced GISTs. In our case successful surgical resection was possible for a huge locally advanced GIST with unusually prolonged treatment of twenty months with imatinib preoperatively. PMID:21483516

    There is an unmet need for efficient near-infrared photothermal transducers for the treatment of highly aggressive cancers and large tumors where the penetration of light can be substantially reduced, and the intra-tumoral nanoparticle transport is restricted due to the presence of hypoxic or necrotic regions. We report the performance advantages obtained by sub 100nm gold nanomatryushkas, comprising concentric gold-silica-gold layers compared to conventional ~150nm silica core gold nanoshells for photothermal therapy of triple negative breast cancer. We demonstrate that a 33% reduction in silica-core-gold-shell nanoparticle size, while retaining near-infrared plasmon resonance, and keeping the nanoparticle surface charge constant, results in a four to five fold tumor accumulation of nanoparticles following equal dose of injected gold for both sizes. The survival time of mice bearing large (>1000mm(3)) and highly aggressive triple negative breast tumors is doubled for the nanomatryushka treatment group under identical photo-thermal therapy conditions.

    There is an unmet need for efficient near-infrared photothermal transducers for the treatment of highly aggressive cancers and large tumors where the penetration of light can be substantially reduced, and the intra-tumoral nanoparticle transport is restricted due to the presence of hypoxic or nectrotic regions. We report the performance advantages obtained by sub 100 nm gold nanomatryushkas, comprising of concentric gold-silica-gold layers compared to conventional ~150 nm silica core gold nanoshells for photothermal therapy of triple negative breast cancer. We demonstrate that a 33% reduction in silica-core-gold-shell nanoparticle size, while retaining near-infrared plasmon resonance, and keeping the nanoparticle surface charge constant, results in a four to five fold tumor accumulation of nanoparticles following equal dose of injected gold for both sizes. The survival time of mice bearing large (>1000 mm3) and highly aggressive triple negative breast tumors is doubled for the nanomatryushka treatment group under identical photo-thermal therapy conditions. The higher absorption cross-section of a nanomatryoshka results in a higher efficiency of photonic to thermal energy conversion and coupled with 4-5X accumulation within large tumors results in superior therapy efficacy.

    Experiments to develop innovative surgical therapy procedures are conventionally conducted on animals, as crucial aspects like tissue removal and bleeding disposition cannot be investigated in vitro. Extracorporeal organ models however reflect these aspects and could thus reduce the use of animals for this purpose fundamentally in the future. The aim of this work was to validate the isolated perfused porcine kidney model with regard to its use for surgical purposes on the basis of histological and radiological procedures. The results show that neither storage nor artificial perfusion led to any structural or functional damage which would affect the quality of the organ. The kidney model is highly suitable for simulating the main aspects of renal physiology and allows a constant calibration of perfusion pressure and tissue temperature. Thus, with only a moderate amount of work involved, the kidney model provides a cheap and readily available alternative to conventional animal experiments; it allows standardised experimental settings and provides valid results.

    2011-01-01

    With rising incidence and emergence of effective treatment options, the management of hepatocellular carcinoma (HCC) is a complex multidisciplinary process. There is still little consensus and uniformity about clinicopathological staging systems. Resection and liver transplantation have been the cornerstone of curative surgical treatments with recent emergence of ablative techniques. Improvements in diagnostics, surgical techniques, and postoperative care have lead to dramatically improved results over the years. The most appropriate treatment plan has to be individualised and depends on a variety of patient and tumour-related factors. Very small HCCs discovered on surveillance have the best outcomes. Patients with advanced cirrhosis and tumours within Milan criteria should be offered transplantation. Resection is best for small solitary tumours with preserved liver function. Ablative techniques are suitable for low volume tumours in patients unfit for either resection or transplantation. The role of downstaging and bridging therapy is not clearly established.

    2013-07-01

    Extramammary Paget's disease (EMPD) is a rare intraepidermal adenocarcinoma that can affect the vulval skin. Surgical excision is the gold-standard treatment, however, recurrence rates are high and extensive excisions can produce long-lasting cosmetic and functional defects. We describe one of the largest case series to-date (n = 6) on the use of topical 5% imiquimod cream as a novel treatment option and discuss our experiences. With the addition of our six cases to the literature, there are now 29 documented cases of vulval EMPD treated with 5% imiquimod cream. Of these, 50% of primary disease cases and 73% of recurrent primary disease cases have achieved clinical resolution with 5% imiquimod therapy alone. These findings suggest that imiquimod provides a viable alternative to surgical excision for vulval EMPD. However, we acknowledge that this is a simple retrospective analysis and that treatment scheduling and follow-up needs investigation in a trial setting. PMID:23815201

    To examine the association between body mass index (BMI), use of menopausal hormone therapy (HT), and incidence of uterine fibroids in postmenopausal women, 610,604 postmenopausal women without prior hysterectomy or diagnosis of fibroids were followed as part of a large United Kingdom prospective cohort study. We used Cox regression models to calculate adjusted relative risks (RRs) of surgically-confirmed fibroids (defined as a hospital admission with uterine fibroids as a primary diagnosis with a related surgical procedure), in relation to BMI and use of HT. During an average of 11.4 years of follow-up, 3561 women were admitted to hospital with surgically-confirmed fibroids. Five-year incidence rates decreased with age, from 0.50% (1 in 200 women) at age 50-54, to 0.11% (1 in 1000 women) at age 75-79. The 5-year rate in postmenopausal women aged 50-54 was about a quarter that seen in premenopausal women of the same age (1 in 200 vs. 1 in 50). Compared with normal weight women, obese women had a RR of surgically-detected fibroids of 1.46 (95% CI 1.33-1.59; p < 0.0001). HT use was associated with a RR of 2.33 (95% CI 2.18-2.49; p < 0.0001) in ever versus never users. When we analysed HT use and BMI together, obese vs. normal weight never users had a RR of 2.00 (95% CI 1.77-2.26): the highest risks were seen in women who were obese and had ever used HT, RR = 3.30 (95% CI 2.88-3.79). Uterine fibroids continue to occur in postmenopausal women; obesity and hormone therapy use are important modifiable risk factors. PMID:25784364

    This 9-week study was designed to determine whether a commercial cognitive-behavioral training program could effectively reduce overt aggression behavior in Chinese young male violent offenders. Sixty-six participants were randomly assigned to receive routine intervention alone (control group) or routine intervention plus Williams LifeSkills Training (WLST group) in a 1:1 ratio. The primary outcome was change scores on the Modified Overt Aggression Scale (MOAS) from baseline to one week following end of training. Secondary outcomes were change scores on the Barratt Impulsiveness Scale-11 (BIS-11) and Cook-Medley Hostility Scale (CMHS). There were significant between-group differences in change of MOAS total score (P < .001) and all sub-scores (Ps < .01) except aggression against property. Between-group differences were also observed in change of BIS-11 and CMHS total score (Ps < 0.05). All results favored the WLST group. These findings suggest WLST has the potential to be an effective intervention to reduce overt aggressive behavior in young male violent offenders. PMID:24375428

    Aim The authors evaluate the results of mini-invasive therapy in patients diagnosed with upside-down stomach. Material and methods From 1998 to 2008, a total of 27 patients diagnosed with upside-down stomach were surgically treated at the 1st Department of Surgery, University Hospital Olomouc. Before the operation, patients were examined endoscopically and a barium swallow was performed. In all 27 patients (100%), the operation was performed electively laparoscopically. The principle of the operation in all cases was reposition of the stomach into the abdominal cavity, resection of the hernial sac and hiatoplasty. In addition, in 15 patients (56%) with reflux symptoms or endoscopic findings of reflux oesophagitis, fundoplication in Nissen's modification was also performed. Fundopexy was indicated in 12 patients (44%). Results In all patients (100%), the operation was performed mini-invasively; conversion to an open procedure was never necessary. In 3 cases (11%), the left pleural cavity was opened during the operation; this was treated by introducing a chest drain. The operation mortality in the patient set was zero; morbidity was 11%. A year after the operation, patients were re-examined, and follow-up endoscopy and barium swallow were performed. Conclusions In all patients diagnosed with upside-down stomach, surgical treatment is indicated due to the risk of developing severe complications. Mini-invasive surgical therapy in the hands of an experienced surgeon is a safe procedure which offers patients all the benefits of mini-invasive therapy with promising short- and long-term results.

    We report a quasi-experimental study of the implementation of an antimicrobial stewardship program in two surgical wards, with a pre-intervention period with just assessment of prescription and an intervention period with a prospective audit on antibiotic prescription model. There was a significant reduction of length of stay and the total days of antimicrobial administration. There were no differences in mortality between groups. The antimicrobial stewardship program led to the early detection of inappropriate empirical antibiotic treatment and was associated with a significant reduction in length of stay and the total duration of antimicrobial therapy.

    Hypospadias is a congenital anomaly of the male urethra that causes significant morbidity in the pediatric male population. The mainstay of treatment is hypospadias repair surgery. However, given the common co-occurrence of microphallus in these patients, surgery remains difficult without adequate tissue for proper reconstruction of the urethra. The use of preoperative testosterone therapy, parenterally or topically, has been a topic of study for several years in urologic literature. This literature review aims to summarize the different studies that have been conducted to address whether preoperative testosterone therapy is beneficial, inconsequential, or detrimental to the surgical and cosmetic outcomes of hypospadias repair as well as to address the differences in routes of administration.

    Malignant tumors of the skin had been a rare entity 2 decades ago. Today they are spread rapidly worldwide. Malignant neoplasms of the skin, the largest human organ, may occur from all structures and layers. While previously skin cancer -occurred mainly after the age of 60, the incidence increases now in younger ages. Strong sunburns in the childhood and before the age of 20 are important risk factors for the development of malignancies of the skin. An increased exposure to UV rays is found especially in the facial skin, where basal cell carcinoma, squamous cell carcinoma, malignant melanoma and Merkel cell carcinomas are the most common malignancies. Early diagnosis of malignancies and therapy-oriented mostly surgical approaches are crucial for the prognosis of all skin cancers. Therefore under the aspect of the increasing incidence these topics will be pointed out according to the latest findings including current multimodal therapy concepts and future treatment options.

    2014-08-01

    Purpose: A subset of patients with oropharyngeal squamous cell carcinoma (OP-SCC) managed with transoral robotic surgery (TORS) and postoperative radiation therapy (PORT) developed soft tissue necrosis (STN) in the surgical bed months after completion of PORT. We investigated the frequency and risk factors. Materials and Methods: This retrospective analysis included 170 consecutive OP-SCC patients treated with TORS and PORT between 2006 and 2012, with >6 months' of follow-up. STN was defined as ulceration of the surgical bed >6 weeks after completion of PORT, requiring opioids, biopsy, or hyperbaric oxygen therapy. Results: A total of 47 of 170 patients (28%) had a diagnosis of STN. Tonsillar patients were more susceptible than base-of-tongue (BOT) patients, 39% (41 of 104) versus 9% (6 of 66), respectively. For patients with STN, median tumor size was 3.0 cm (range 1.0-5.6 cm), and depth of resection was 2.2 cm (range 1.0-5.1 cm). Median radiation dose and dose of fraction to the surgical bed were 6600 cGy and 220 cGy, respectively. Thirty-one patients (66%) received concurrent chemotherapy. Median time to STN was 2.5 months after PORT. All patients had resolution of STN after a median of 3.7 months. Multivariate analysis identified tonsillar primary (odds ratio [OR] 4.73, P=.01), depth of resection (OR 3.12, P=.001), total radiation dose to the resection bed (OR 1.51 per Gy, P<.01), and grade 3 acute mucositis (OR 3.47, P=.02) as risk factors for STN. Beginning May 2011, after implementing aggressive avoidance of delivering >2 Gy/day to the resection bed mucosa, only 8% (2 of 26 patients) experienced STN (all grade 2). Conclusions: A subset of OP-SCC patients treated with TORS and PORT are at risk for developing late consequential surgical bed STN. Risk factors include tonsillar location, depth of resection, radiation dose to the surgical bed, and severe mucositis. STN risk is significantly decreased with carefully avoiding a radiation dosage of >2 Gy/day to the

    Summary Severe acute pancreatitis (SAP) management has changed over the last fifteen years, and from too aggressive behaviour, we moved to a cautious one. In every case, we can appreciate defect of extremist conceptual position. We reviewed our strategy on disease treatment, and we analyzed treatment of single cases. We collected 4 SAP cases from January 2009 to January 2010. All patients were septic, and we adopted the same approach for all of them, avoiding surgery without peritoneal infection. In all patients we placed jejumostomy and, after cleaning of septic site, we started immediate enteral nutrition (EN). Antibiotic therapy against Gram+, Gram− and antifugal drug had been started. No one died and all patients were back to an active life even if social costs are considerably high especially due to very long hospital stay. PMID:24629818

    Surgical site occurrences are observed in up to 60% of inpatient surgical procedures in industrialised countries. The most relevant postoperative complication is surgical site infection (SSI) because of its impact on patient outcomes and enormous treatment costs. Literature reviews ('SSI', 'deep sternal wound infections' (DSWI), 'closed incision negative pressure wound therapy' (ciNPT) were performed by electronically searching MEDLINE (PubMed) and subsequently using a 'snowball' method of continued searches of the references in the identified publications. Search criteria included publications in all languages, various study types and publication in a peer-reviewed journal. The SSI literature search identified 1325, the DSWI search 590 and the ciNPT search 103 publications that fulfilled the search criteria. Patient-related SSI risk factors (diabetes mellitus, obesity, smoking, hypertension, female gender) and operation-related SSI risk factors (re-exploration, emergency operations, prolonged ventilation, prolonged operation duration) exist. We found that patient- and operation-related SSI risk factors were often different for each speciality and/or operative procedure. Based on the evidence, we found that high-risk incisions (sternotomy and incisions in extremities after high-energy open trauma) are principally recommended for ciNPT use. In 'lower'-risk incisions, the addition of patient-related or operation-related risk factors justifies the application of ciNPT. PMID:27547962

    Endometrial cancer (EC) is the most common female genital malignancy in the USA. Most carcinomas arising from the uterus are estrogen dependent and are associated with obesity and hypertension. They are designated type I ECs and typically, due to their early diagnosis secondary to postmenopausal bleeding, have a good prognosis. By contrast, type II ECs develop in older patients, are not hormone dependent and are responsible for most recurrences and deaths from EC. Uterine serous cancer constitutes up to 10% of all endometrial tumors, and represents the most biologically aggressive variant of type II EC. This article will describe the most salient molecular markers that have been identified in uterine serous cancer, thus far with emphasis on the use of erbB2 (HER2/neu) as the first of a series of therapeutic markers for the treatment of this highly-aggressive subset of ECs.

    As the American Academy of Periodontology indicates, the treatment of chronic periodontitis should be achieved in the least invasive manner through non-surgical periodontal therapy. However, complete removal of subgingival plaque and calculus is hindered with increasing probing depth (PD) and furcation involvement using hand, sonic or ultrasonic instruments. Many authors have suggested that the use of laser as an adjunct to scaling and root planing (SRP) might improve the effectiveness of conventional periodontal treatment. The aim of this study was to evaluate potassium-titanyl-phosphate (KTP) laser in non-surgical periodontal therapy. Seven hundred and thirty sites with probing depths of 4-6 mm were involved in the study. The sites were divided into four groups: control (SRP, chlorhexidine gel 0.5%), group A (SRP, chlorhexidine gel 0.5%, three sessions of KTP laser irradiation); group B (SRP, three sessions of KTP laser irradiation) and group C (SRP, irrigation with povidone-iodine 10%, three sessions of KTP laser irradiation). KTP laser was used with the following parameters: output power 0.6 W, time on 10 ms, time off 50 ms, 30 s per irradiation, fluence 19 J/cm(2). All the sites showed improvement in all clinical parameters. Clinical attachment loss (CAL), pocket probing depths (PPDs) and bleeding on probing (BOP), especially in the lased groups, showed significant results (P < 0.001). Our experience showed KTP laser to be a significant help in SRP; nevertheless, more studies are necessary to confirm our results. PMID:19936872

    Treatment of gastroesophageal reflux disease in the United States today is binary, with the majority of patients with gastroesophageal reflux disease being treated with antisecre-tory medications and a minority of patients, typically those with volume regurgitation, undergoing Nissen fundoplication. However, there has been increasing dissatisfaction with proton pump inhibitor therapy among a significant number of patients with gastroesophageal reflux disease owing to cost, side effects, and refractory symptoms, and there has been a general reluctance to undergo surgical fundoplication due to its attendant side-effect profile. As a result, a therapy gap exists for many patients with gastroesophageal reflux disease. Alternative techniques are available for these gap patients, including 2 endoscopic fundoplication techniques, an endoscopic radiofrequency energy delivery technique, and 2 minimally invasive surgical procedures. These alternative techniques have been extensively evaluated; however, there are limitations to published studies, including arbitrary definitions of success, variable efficacy measurements, deficient reporting tools, inconsistent study designs, inconsistent lengths of follow-up postintervention, and lack of comparison data across techniques. Although all of the techniques appear to be safe, the endoscopic techniques lack demonstrable reflux control and show variable symptom improvement and variable decreases in proton pump inhibitor use. The surgical techniques are more robust, with evidence for adequate reflux control, symptom improvement, and decreased proton pump inhibitor use; however, these techniques are more difficult to perform and are more intrusive. Additionally, these alternative techniques have only been studied in patients with relatively normal anatomy. The field of gastroesophageal reflux disease treatment is in need of consistent definitions of efficacy, standardized study design and outcome measurements, and improved reporting

    PubMed

    1985-11-29

    True prophylaxis of intra-abdominal nongynecologic infections is limited to elective, nonemergency surgery and is best shown in three clean-contaminated surgical procedures. All of these have an infection rate of approximately 10 to 20 percent and include all colon resection surgery, most gastric surgery, and about one third of the cholecystectomies for chronic calculous cholecystitis. Each of these three surgical procedures has a somewhat different pattern of bacterial pathogens. The most useful comparative studies of early preoperative therapy have been performed in cases of suspected appendicitis (50 percent of which usually show perforation or gangrene at the time of surgery) and penetrating abdominal wounds (80 percent of which usually enter some part of the bowel and theoretically soil the peritoneum). These procedures are usually classified as contaminated, with a 20 to 30 percent infection rate, or dirty, with a more than 30 percent infection rate, depending upon several factors. Comparative investigations of intraoperative and postoperative antibiotic therapy of established intra-abdominal infections are more difficult to obtain because of the heterogeneity of the sites, organisms, and medical and surgical therapy. The initial pathogens causing secondary peritonitis and hepatic, perirectal, diverticular, and most other types of intraperitoneal abscesses are mixed coliforms and anaerobes, with emphasis on the anaerobes. Retroperitoneal abscesses, pancreatic abscesses, and biliary tract infections are predominantly caused by coliforms. The organisms responsible for these early infections are usually community-acquired rather than more antibiotic-resistant hospital-acquired bacteria. Considering the availability of a large number of effective broad-spectrum antibacterial agents and therapeutic combinations, it has become increasingly difficult to assess the rightful place of any new prospective antimicrobial regimen unless it has quite unique characteristics

    Abstract Locally advanced gastric cancer (LAGC) is best treated with surgical resection. Bevacizumab in combination with chemotherapy has shown promising results in treating advanced gastric cancer. This study aimed to investigate the efficacy of neoadjuvant chemotherapy using the docetaxel/oxaliplatin/5-FU (DOF) regimen and bevacizumab in LAGC patients. Eighty LAGC patients were randomized to receive DOF alone (n = 40) or DOF plus bevacizumab (n = 40) as neoadjuvant therapy before surgery. The lesions were evaluated at baseline and during treatment. Circulating tumor cells (CTCs) were counted using the FISH test. Patients were followed up for 3 years to analyze the disease-free survival (DFS) and overall survival (OS). The total response rate was significantly higher in the DOF plus bevacizumab group than the DOF group (65% vs 42.5%, P = 0.0436). The addition of bevacizumab significantly increased the surgical resection rate and the R0 resection rate (P < 0.05). The DOF plus bevacizumab group showed significantly greater reduction in CTC counts after neoadjuvant therapy in comparison with the DOF group (P = 0.0335). Although the DOF plus bevacizumab group had significantly improved DFS than the DOF group (15.2 months vs 12.3 months, P = 0.013), the 2 groups did not differ significantly in OS (17.6 ± 1.8 months vs 16.4 ± 1.9 months, P = 0.776. Cox proportional model analysis showed that number of metastatic lymph nodes, CTC reduction, R0 resection, and neoadjuvant therapy are independent prognostic factors for patients with LAGC. Neoadjuvant of DOF regimen plus bevacizumab can improve the R0 resection rate and DFS in LAGC. These beneficial effects might be associated with the reduction in CTC counts. PMID:26496252

    There are no prospective studies of aggressive non-Hodgkin lymphoma (NHL) treated with CHOP in sub-Saharan Africa. We enrolled adults with aggressive NHL in Malawi between June 2013 and May 2015. Chemotherapy and supportive care were standardized, and HIV+ patients received antiretroviral therapy (ART). Thirty-seven of 58 patients (64%) were HIV+. Median age was 47 years (IQR 39–56), and 35 (60%) were male. Thirty-five patients (60%) had stage III/IV, 43 (74%) B symptoms, and 28 (48%) performance status ≥2. B-cell NHL predominated among HIV+ patients, and all T-cell NHL occurred among HIV- individuals. Thirty-one HIV+ patients (84%) were on ART for a median 9.9 months (IQR 1.1–31.7) before NHL diagnosis, median CD4 was 121 cells/μL (IQR 61–244), and 43% had suppressed HIV RNA. HIV+ patients received a similar number of CHOP cycles compared to HIV- patients, but more frequently developed grade 3/4 neutropenia (84% vs 31%, p = 0.001), resulting in modestly lower cyclophosphamide and doxorubicin doses with longer intervals between cycles. Twelve-month overall survival (OS) was 45% (95% CI 31–57%). T-cell NHL (HR 3.90, p = 0.017), hemoglobin (HR 0.82 per g/dL, p = 0.017), albumin (HR 0.57 per g/dL, p = 0.019), and IPI (HR 2.02 per unit, p<0.001) were associated with mortality. HIV was not associated with mortality, and findings were similar among patients with diffuse large B-cell lymphoma. Twenty-three deaths were from NHL (12 HIV+, 11 HIV-), and 12 from CHOP (9 HIV+, 3 HIV-). CHOP can be safe, effective, and feasible for aggressive NHL in Malawi with and without HIV. PMID:26934054

    There are no prospective studies of aggressive non-Hodgkin lymphoma (NHL) treated with CHOP in sub-Saharan Africa. We enrolled adults with aggressive NHL in Malawi between June 2013 and May 2015. Chemotherapy and supportive care were standardized, and HIV+ patients received antiretroviral therapy (ART). Thirty-seven of 58 patients (64%) were HIV+. Median age was 47 years (IQR 39-56), and 35 (60%) were male. Thirty-five patients (60%) had stage III/IV, 43 (74%) B symptoms, and 28 (48%) performance status ≥ 2. B-cell NHL predominated among HIV+ patients, and all T-cell NHL occurred among HIV- individuals. Thirty-one HIV+ patients (84%) were on ART for a median 9.9 months (IQR 1.1-31.7) before NHL diagnosis, median CD4 was 121 cells/μL (IQR 61-244), and 43% had suppressed HIV RNA. HIV+ patients received a similar number of CHOP cycles compared to HIV- patients, but more frequently developed grade 3/4 neutropenia (84% vs 31%, p = 0.001), resulting in modestly lower cyclophosphamide and doxorubicin doses with longer intervals between cycles.

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a shorter

    The efficacy of negative pressure wound therapy (NPWT) in the treatment of skin defect wounds has been established, but it is difficult to apply to hand surgery because of the easy occurrence of air leaks. We report two cases of performing NPWT with surgical gloves. Case1: A 37-year-old male was injured on his right dorsal hand from a punch. He presented to our hospital three days after the injury because of swelling and pain. The wound was infected and contused, so wound lavage and debridement (W&D) were performed under local anesthesia. The infected condition didn't improve after antimicrobial infusion, so W&D were performed again 8 days after the first visit. Then W&D were performed every day, and the infection subsided 15 days after the first visit. NPWT was initiated for the purpose of managing exudate and the wound condition, and healthy granulation tissue formed gradually. Finally, transpositional flap and full-thickness skin graft were performed on day 29. Case2: A 43-year-old male accidentally sustained a high pressure injection of oil into his dorsal hand. He presented to our hospital the next day, and W&D were performed. W&D were performed again two days after the first visit, and artificial dermis was applied over a part of the wound that was impossible to close. A decision was made to apply NPWT and a surgical glove for the purpose of reducing swelling and managing wound exudate. The swelling decreased and granulation tissue formed gradually, then nine days after the first visit a sural nerve graft was applied to bridge the defective area, and a full thickness skin graft was applied. We achieved good wound closure and hand function recovery after using NPWT and a surgical glove. PMID:26370041

    This paper provides a description of the Witmer Wellness Center, the first successful military application of dialectical behavior therapy in a theater of war. Dialectical behavior therapy is a dynamic and provocative evidenced-based modification of cognitive behavioral treatment developed by Dr Marsha Linehan for patients with severe emotional dysregulation. One of the primary concepts of dialectical behavior therapy is that self-harming behaviors are learned, and provide evidence of maladaptive coping that is reinforced in an invalidating environment. Dialectical behavior therapy recommends a hierarchy of goals to effectively address the behaviors associated with dysregulation. Chief among these goals is reducing risk of violence to self or others. Dialectical behavior therapy is especially well-suited for the complex and dynamic environment of the noncontiguous battlefield with its chronic threat of ultraviolence, strain of nonresponse, shifting rules of engagement, and extended duration and frequency of combat deployments. The Witmer Wellness Center program uses an intensive outpatient organizational structure and minimal, but innovative, modifications to standard dialectical behavior therapy designed to meet the special requirements of Warriors in a combat zone. The Wellness Center program was designed and implemented during Operation Iraqi Freedom 07-09, at a time during the troop surge when suicide rates among US forces had reached an unprecedented level.

    An 8-year-old spayed female Netherland Dwarf rabbit presented with a two-month history of dyspnea and snoring. A computed tomography (CT) scan of the head revealed mass lesions in the right nasal cavity. Surgical exenteration of the lesions was performed, and the histopathological diagnosis was an intranasal adenocarcinoma. On the basis of this diagnosis, radiotherapy was planned and consisted of eight fractions of 6 Gy administered once a week. After the completion of radiation therapy, the soft tissue density in the right nasal cavity, as detected by CT, significantly decreased. The prognosis has remained good for over 3 years after treatment. This paper is the first to describe the clinical and pathological features of an intranasal tumor in a rabbit. PMID:25649953

    Most prolactin-secreting pituitary adenomas demonstrate slow growth and are effectively managed with medical/surgical therapy. Rarely, these tumors can behave aggressively with rapid growth and invasion of local tissues, and are refractory to medical, surgical, or radio-surgical therapies. We report a case of a prolactin-secreting adenoma in a young woman, which became progressively aggressive and refractory to usual treatment modalities, but responded to treatment with the chemotherapeutic agent temozolomide. In addition, we review the literature for treatment of refractory adenomas with temozolomide. The clinical and pathologic characteristics of aggressive prolactin-secreting adenomas are reviewed, as well as their response to dopamine agonists, surgery, radiotherapy, and chemotherapy.

    Clinical Question In adults with acute plantar fasciitis whose symptoms have not been relieved with the conventional regimen of NSAIDS, stretching and lifestyle modification, do the addition of orthotics (prefabricated or custom fitted) reduce pain and improve function compared with other non-surgical treatments (manipulative chiropractic, physical therapy and/or heel steroid injections)? Answer Yes. Studies have shown that orthotics, both prefabricated and custom fitted, reduce pain and improve function in adults with acute plantar fasciitis with few risks or side effects. Used alone or in addition to conventional therapy (NSAIDs, stretching, lifestyle modification), orthotics are effective and well tolerated by patients for short-term pain relief and improved function. Prefabricated orthotics are less costly and provide similar relief to more expensive custom orthotics. Level of Evidence of the Answer A Search Terms Plantar fasciitis, heel pain, treatment, orthotics, Limits Adult, human, English, Review, Randomized-Control Trials, Systematic Reviews, adults age 18 or more, publication dates 2004 to present. Date Search was Conducted January 16, 2014; updated January 20, 2015 Inclusion Criteria Recent published systematic reviews, randomized controlled, meta-analyses; adults with confirmed acute or recent diagnosis of plantar fasciitis. Exclusion Criteria Studies older than 10 years, children, adolescents less than 18 years of age, chronic or recalcitrant plantar fasciitis. PMID:26855444

    This study tested the feasibility of a high throughput metagenomic approach to analyze the pre- and posttreatment of subgingival plaque in two subjects with aggressive periodontitis. DNA was extracted from subgingival samples and subjected to PCR amplification of the c2-c4 regions of the 16S rDNA using primers with bar codes to identify individual samples. The PCR products were pooled and sequenced for the v4 region of the 16S rDNA using the 454 FLX standard platform. The results were analyzed for species/phylotypes in the Human Oral Microbiome Database (HOMD) and Ribosomal Database Project (RDP) database. The sequencing of the amplicons resulted in 24,673 reads and identified 208 species/phylotypes. Of those, 129 species/phylotypes were identified in both patients but their proportions varied. While >120 species/phylotypes were identified in all samples, 28-42 species/phylotypes cumulatively represent 90% of all subgingival bacteria in each sample. The remaining species/phylotypes each constituted ≤0.2% of the total subgingival bacteria. In conclusion, the subgingival microbiota are characterized by high species richness dominated by a few species/ phylotypes. The microbiota changed after periodontal therapy. High throughput metagenomic analysis is applicable to assess the complexity and changes of the subgingival microbiota. PMID:23341849

    Significant uncertainty exists in regard to the efficacy of maintenance therapy after high-dose chemotherapy (HDC) as well as autologous stem cell transplantation (ASCT) for the treatment of patients with aggressive lymphoma. A systematic review was performed to evaluate the effectiveness of post-ASCT maintenance therapy in patients with relapsed/refractory lymphoma. A comprehensive literature search yielded 4476 studies and a total of 42 studies (11 randomized controlled trials [RCT], 9 retrospective comparative studies, and 22 single-arm studies) were included in the systematic review. There was significant heterogeneity in study design, chemotherapeutic regimens, post-ASCT maintenance strategies, patient enrollment criteria, and study endpoints. Our findings suggest that post-ASCT maintenance immune-targeting strategies, including PD-1/PD-L1 blocking antibodies, rituximab, and brentuximab, may improve progression-free survival but not overall survival. Collectively, the results indicate a need for testing new strategies with well-designed and adequately powered RCTs to better address the role of post-ASCT maintenance in relapsed/refractory lymphomas.

    Selection of the optimal surgical and interventional therapies for advanced colorectal cancer liver metastases (CRLM) requires multidisciplinary discussion of treatment strategies early in the trajectory of the individual patient's care. This paper reports on expert consensus on locoregional and interventional therapies for the treatment of advanced CRLM. Resection remains the reference treatment for patients with bilateral CRLM and synchronous presentation of primary and metastatic cancer. Patients with oligonodular bilateral CRLM may be candidates for one-stage multiple segmentectomies; two-stage resection with or without portal vein embolization may allow complete resection in patients with more advanced disease. After downsizing with preoperative systemic and/or regional therapy, curative-intent hepatectomy requires resection of all initial and currently known sites of disease; debulking procedures are not recommended. Many patients with synchronous primary disease and CRLM can safely undergo simultaneous resection of all disease. Staged resections should be considered for patients in whom the volume of the future liver remnant is anticipated to be marginal or inadequate, who have significant medical comorbid condition(s), or in whom extensive resections are required for the primary cancer and/or CRLM. Priority for liver-first or primary-first resection should depend on primary tumour-related symptoms or concern for the progression of marginally resectable CRLM during treatment of the primary disease. Chemotherapy delivered by hepatic arterial infusion represents a valid option in patients with liver-only disease, although it is best delivered in experienced centres. Ablation strategies are not recommended as first-line treatments for resectable CRLM alone or in combination with resection because of high local failure rates and limitations related to tumour size, multiplicity and intrahepatic location.

    Objectives The period of post-operative treatment before surgical wounds are completely closed remains a key window, during which one can apply new technologies that can minimise complications. One such technology is the use of negative pressure wound therapy to manage and accelerate healing of the closed incisional wound (incisional NPWT). Methods We undertook a literature review of this emerging indication to identify evidence within orthopaedic surgery and other surgical disciplines. Literature that supports our current understanding of the mechanisms of action was also reviewed in detail. Results A total of 33 publications were identified, including nine clinical study reports from orthopaedic surgery; four from cardiothoracic surgery and 12 from studies in abdominal, plastic and vascular disciplines. Most papers (26 of 33) had been published within the past three years. Thus far two randomised controlled trials – one in orthopaedic and one in cardiothoracic surgery – show evidence of reduced incidence of wound healing complications after between three and five days of post-operative NPWT of two- and four-fold, respectively. Investigations show that reduction in haematoma and seroma, accelerated wound healing and increased clearance of oedema are significant mechanisms of action. Conclusions There is a rapidly emerging literature on the effect of NPWT on the closed incision. Initiated and confirmed first with a randomised controlled trial in orthopaedic trauma surgery, studies in abdominal, plastic and vascular surgery with high rates of complications have been reported recently. The evidence from single-use NPWT devices is accumulating. There are no large randomised studies yet in reconstructive joint replacement. Cite this article: Bone Joint Res 2013;2:276–84.

    Background Five or more colorectal liver metastases (CRLM) are considered marginally resectable and cannot be treated solely by hepatic resection (Hr). This study investigated the long-term effectiveness of surgical treatment using microwave coagulo-necrotic therapy (MCN) and/or Hr for marginally resectable or unresectable multiple CRLM. Methods This study retrospectively analyzed 82 consecutive CRLM patients with ≥5 CRLM who underwent MCN, Hr, or both, at our institution from 1994 to 2012. Presuming all CRLM were resected curatively, virtual remnant liver volume was calculated using preoperative computed tomography or magnetic resonance imaging. Virtual remnant liver volume <30% was defined as unresectable. Patients were divided into marginally resectable (Group Y; n=29) and unresectable (Group N; n=53). Overall and recurrence-free survival were assessed. Results Mean maximum tumor diameter and tumor number were 3.1 and 6.0 cm in Group Y and 3.3 and 11.3 cm in Group N. Surgical methods included MCN (n=16), MCN+Hr (n=9), and Hr (n=4) in Group Y, and MCN (n=28) and MCN+Hr (n=25) in Group N. One- and 2-year recurrence-free survival rates were 38.0% and 22.8% in Group Y, and 18.9% and 3.8% in Group N (P=0.01). However, 1-, 3-, and 5-year overall survival rates of Group N (86.8%, 44.6%, and 33.7%, respectively) were similar to those of Group Y (82.8%, 51.4%, and 33.3%, respectively; P= not significant each). Conclusion MCN may improve survival for patients with unresectable multiple CRLM, similar to that in patients with marginally resectable multiple CRLM. PMID:26955286

    PubMed Central

    2016-01-01

    High-grade T1 bladder cancer has a poor prognosis due to a higher incidence of recurrence and progression than other nonmuscle invasive bladder cancer; thus patients with high-grade T1 have to be carefully monitored and managed. If patients are diagnosed with high-grade T1 at initial transurethral resection (TUR), a second TUR is strongly recommended regardless of whether muscle layer is present in the specimen because of the possibility of understating due to incomplete resection. Since high-grade T1 disease shows diverse clinical courses, individual approaches are recommended for treatment. In cases with low risk of progression, cystectomy could represent overtreatment and deteriorate quality of life irreversibly, while, in those with high risk, bacillus Calmette-Guérin (BCG) therapy may worsen survival by delaying definitive therapy. Therefore, a strategy for predicting prognosis based on the risk of progression is needed for managing high-grade T1 disease. Molecular risk classifiers predicting the risk of progression and response to BCG may help identify the optimal management of high-grade T1 disease for each individual. PMID:27326407

    The "robotic-assisted liver tumor coagulation therapy" (RALTCT) system is a promising candidate for large liver tumor treatment in terms of accuracy and speed. A prerequisite for effective therapy is accurate surgical planning. However, it is difficult for the surgeon to perform surgical planning manually due to the difficulties associated with robot-assisted large liver tumor therapy. These main difficulties include the following aspects: (1) multiple needles are needed to destroy the entire tumor, (2) the insertion trajectories of the needles should avoid the ribs, blood vessels, and other tissues and organs in the abdominal cavity, (3) the placement of multiple needles should avoid interference with each other, (4) an inserted needle will cause some deformation of liver, which will result in changes in subsequently inserted needles' operating environment, and (5) the multiple needle-insertion trajectories should be consistent with the needle-driven robot's movement characteristics. Thus, an effective multiple-needle surgical planning procedure is needed. To overcome these problems, we present an automatic multiple-needle surgical planning of optimal insertion trajectories to the targets, based on a mathematical description of all relevant structure surfaces. The method determines the analytical expression of boundaries of every needle "collision-free reachable workspace" (CFRW), which are the feasible insertion zones based on several constraints. Then, the optimal needle insertion trajectory within the optimization criteria will be chosen in the needle CFRW automatically. Also, the results can be visualized with our navigation system. In the simulation experiment, three needle-insertion trajectories were obtained successfully. In the in vitro experiment, the robot successfully achieved insertion of multiple needles. The proposed automatic multiple-needle surgical planning can improve the efficiency and safety of robot-assisted large liver tumor therapy

    Responsive-Aggression Regulation Therapy (Re-ART) Outpatient is a cognitive behavioral-based intervention for adolescents and young adults (16-24 years) with severe aggressive behavioral problems. This pilot study (N = 26) examined the level of program integrity (PI; that is, the delivery of the intervention as it is originally intended) of Re-ART. We also investigated the pre- and post-test changes in several outcome variables, and the relation between the level of PI and these changes. Participants were recruited from three different outpatient forensic settings. Results showed that the PI of half of the treatments was not sufficient (e.g., the intensity of the program was too low and some standard modules were not offered). In addition, this pilot study demonstrated that sufficient PI was related to positive changes in aggression, cognitive distortions, social support, coping (reported by therapist), and distrust (responsiveness to treatment).

    Radiation therapy (RT) is one of the mainstay treatments for prostate cancer (PCa). The potentially curative approaches can provide satisfactory results for many patients with non-metastatic PCa; however, a considerable number of individuals may present disease recurrence and die from the disease. Exploiting the rich molecular biology of PCa will provide insights into how the most resistant tumor cells can be eradicated to improve treatment outcomes. Important for this biology-driven individualized treatment is a robust selection procedure. The development of predictive biomarkers for RT efficacy is therefore of utmost importance for a clinically exploitable strategy to achieve tumor-specific radiosensitization. This review highlights the current status and possible opportunities in the modulation of four key processes to enhance radiation response in PCa by targeting the: (1) androgen signaling pathway; (2) hypoxic tumor cells and regions; (3) DNA damage response (DDR) pathway; and (4) abnormal extra-/intracell signaling pathways. In addition, we discuss how and which patients should be selected for biomarker-based clinical trials exploiting and validating these targeted treatment strategies with precision RT to improve cure rates in non-indolent, localized PCa.

    The “robotic-assisted liver tumor coagulation therapy” (RALTCT) system is a promising candidate for large liver tumor treatment in terms of accuracy and speed. A prerequisite for effective therapy is accurate surgical planning. However, it is difficult for the surgeon to perform surgical planning manually due to the difficulties associated with robot-assisted large liver tumor therapy.

    Free floating thrombus in the proximal descending aorta is an uncommon and dangerous condition that can be associated with acute peripheral embolization. The few cases described were solved with surgical and/or medical therapy. We report the case of a patient with acute left arm ischemia secondary to the presence of floating thrombus in the proximal descending aorta extending into the left subclavian artery, solved with combined endovascular and surgical therapy. Treatment was successfully performed with thrombembolectomy combined with temporary deployment, into the descending aorta, of a Wallstent in a 'basket-fashion' to avoid distal embolization secondary to thrombus fragmentation. At 1 year follow-up the patient remained symptom-free.

    Pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have become life-saving therapeutic tools for patients with cardiac arrhythmia. Complications include thrombosis, embolism and infections at a highly variable rate. Surgical removal of the infected device has been perceived as the only way to guarantee a successful outcome and to reduce the high risk of mortality. Recently, a transvenous extraction method has been developed to remove infected intracardiac leads without sternotomy. This survey was designed to evaluate the outcome of an approach combining antibiotic therapy with non-surgical transvenous complete removal for the management of cardiac device infections (CDIs). We reviewed case-histories of 121 patients (105 with PM and 16 with ICD infections). The aim of our retrospective survey was to ascertain that a non-invasive transvenous complete removal of the infected devices is safe and effective when associated with appropriate antibiotic therapy starting 10 days before the procedure and extending to at least three weeks after. The infected devices were successfully removed in all patients with a non-surgical transvenous technique. The infections were most frequently caused by coagulase-negative staphylococci (70%), Staphylococcus aureus (14%), and Gram-negative rods (12%). Polymicrobial infections were documented in 19 patients and represent 16% of all device-related infections. The removal of the devices was done during antibiotic therapy, administered for a median of 26 days (range 23 to 45 days). Neither fatalities nor relapse of infections were recorded in the patient population during the one-year follow-up visits. According to our experience, CDIs can be treated with antibiotic therapy and non-surgical removal of the entire infected device, thus allowing a successful reimplantation. This procedure prevents recurrent infections and operative mortality. PMID:16736884

    Aims and Objectives: Due to open femoral physis, the therapy of patellar instability in children and adolescents is challenging. We developed a surgical technique, modified form of the "Adductor-Sling-Technique" by Sillanpää which offers a surgical treatment to avoid damage to the femoral physis. The purpose of this study is to determine whether there is a benefit in the clinical outcome for patients operated by the "modified Adductor Sling Technique" in comparison to patients with other surgical procedures. Materials and Methods: Twenty "modified Adductor Sling" reconstructions in 19 patients (age 11-24) were included in the study until now, 15 patients with open physis and 4 patients with closed physis with special indications. Since 2010 "modified Adductor Sling" reconstruction was performed by looping the gracilis tendon around the adductor magnus tendon and attaching it at the medial facette of the patella. Clinical outcome was retrospectively evaluated at a mean follow-up period of 1.3 years (range 0.5-3.6). The evaluation also included Lysholm Score, Kujala Score and DGU score. Statistical analysis was performed using IBM®SPSS®Statistics Version 21. A P value less than 0.5 was considered significant. Results: The average age at the time of operation was 14.9 years (range 11.2-24.3). Recurrent dislocation occurred in 4 out of 20 cases (20%). It was noticeable that out of those 4 patients 2 patients had a lateral release in addition to the "modified Adductor Sling Technique" due to lateral hyperpression. No other patients had a lateral release in our patient population. Also, out of those 4 patients 3 patients had an additional maltracking of the patella, caused by a high TTTG, severe trochlea dysplasia or additional axial deformity. The overall Kujala Score was 87 (range 46-100) points, in patients without re-dislocation it was 94 (range 46-100) points. The overall Lysholm Score was 85 (range 39-100) points, in the group without re-dislocation 90 (range

    Aggressive fibromatosis is a poorly defined, locally aggressive, yet histologically benign fibroblastic proliferative lesion that may occur in the head and neck. The lesion is highly cellular and locally infiltrative and has a propensity to invade and erode bone, compromising vital structures within the head and neck. However, it is not a true malignancy because it does not have malignant cytologic characteristics nor does it metastasize. We present two cases of aggressive fibromatosis occurring in young adult men. The first case involved a rapidly enlarging mass of the anterior maxilla that involved the upper lip, nasal alae, nasal septum, inferior turbinates, and hard palate. The patient underwent incisional biopsy to confirm the diagnosis. Because of difficulty in determining the actual margins of this extensive lesion and the significant morbidity that would have resulted from surgical resection, we elected to treat this patient with chemotherapy and radiation therapy. The second case was an extensive lesion involving the right temporal bone, pterygomaxillary space, and infratemporal, temporal, and middle cranial fossae. Incisional biopsy confirmed the diagnosis. Because of the lack of functional and cosmetic deficits and the unavoidable morbidity of a surgical resection, this patient was treated with radiation therapy. Although wide field resection is the most satisfactory form of treatment, in situations in which this modality would result in unacceptable morbidity or if surgical margins are positive, then radiation therapy and chemotherapy should be considered. Support for these therapeutic modalities is found in larger series of cases outside the head and neck.

    Background Previous research suggests that patients with panic disorder exhibit higher levels of aggression than patients with other anxiety disorders. This aggression is associated with more severe symptomatology and interpersonal problems. However, few studies have examined whether higher levels of aggression are associated with a worse treatment response in this population. Methods The present study sought to examine the association of aggression with panic disorder symptom severity in a sample of 379 patients who participated in a trial examining long-term strategies for the treatment of panic disorder. Results We found that aggression was significantly associated with higher baseline levels of panic disorder symptoms, anxiety, depression, and functional impairment. Further, we found that patients higher in aggression did not achieve the same level of improvement in general anxiety symptoms during treatment compared to patients lower in aggression, even when controlling for baseline anxiety symptom severity. Conclusion These results suggest that more research is needed concerning patients with anxiety disorders with higher aggression, as they may be a group in need of additional treatment considerations.

    Introduction Aggressive periodontitis comprises a group of rare, severe, rapidly progressive form of periodontitis. Conventional treatment includes mechanical debridement augmented with adjunctive antimicrobial therapy. Development of antibiotic resistance has led to use of lasers. Photodynamic therapy (PDT) is a novel non-invasive therapeutic approach with increased site and pathogen specificity. This study compares PDT and Lasers as an adjunct to conventional Scaling in the treatment of patients with aggressive periodontitis. Materials and Methods Fifteen untreated aggressive periodo-ntitis patients were randomly assigned in a split mouth design for one of the following treatment modalities: 1) SRP alone; (2) SRP + Diode Laser irradiation with 810 nm at 1W, continuous mode for 30 sec per tooth; (3) SRP + PDT on “0” day; (4) SRP + PDT on “0”, 7th and 21st day. The clinical parameters included PI, BOP, PPD, CAL recorded at the baseline & 3rd month. The site with greatest probing pocket depth (PPD) was selected from each quadrant for bacterial sampling and cultured for Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis & Prevotella intermedia. Results Statistically significant reduction in clinical & microbial parameters was seen. Sites 4 showed a greater reduction compared to other groups. Conclusion Photodynamic therapy is a valuable treatment modality adjunctive to conventional scaling and root planing. PMID:27042576

    We describe a case report that documented the efficacy and safety of medical therapy in stabilizing and resolving a complex and unstable aortic atheroma after a relatively short period. The patient had a large protruding, mobile, calcified nonulcerated atheroma involving the descending aorta and was therefore treated with aggressive combination therapy with high statin dosages (atorvastatin = 80 mg) and dual antiplatelet treatment (clopidogrel = 75 mg and aspirin = 100 mg). At follow-up, the echocardiogram showed a significant regression in the atheroma volume, with no signs suggestive of ulceration on its surface with the complete mobile component resolution.

    Here, we found that BTG1 overexpression inhibited proliferation, migration and invasion, induced G2/M arrest, differentiation, senescence and apoptosis in BGC-823 and MKN28 cells (p < 0.05). BTG1 transfectants showed a higher mRNA expression of Cyclin D1 and Bax, but a lower mRNA expression of cdc2, p21, mTOR and MMP-9 than the control and mock (p < 0.05). After treated with cisplatin, MG132, paclitaxel and SAHA, both BTG1 transfectants showed lower mRNA viability and higher apoptosis than the control in both time- and dose-dependent manners (p < 0.05) with the hypoexpression of chemoresistance-related genes (slug, CD147, GRP78, GRP94, FBXW7 TOP1, TOP2 and GST-π). BTG1 expression was restored after 5-aza-2'-deoxycytidine treatment in gastric cancer cells. BTG1 expression was statistically lower in gastric cancer than non-neoplastic mucosa and metastatic cancer in lymph node (p < 0.05). BTG1 expression was positively correlated with depth of invasion, lymphatic and venous invasion, lymph node metastasis, TNM staging and worse prognosis (p < 0.05). The diffuse-type carcinoma showed less BTG1 expression than intestinal- and mixed-type ones (p < 0.05). BTG1 overexpression suppressed tumor growth and lung metastasis of gastric cancer cells by inhibiting proliferation, enhancing autophagy and apoptosis in xenograft models. It was suggested that down-regulated BTG1 expression might promote gastric carcinogenesis partially due to its promoter methylation. BTG1 overexpression might reverse the aggressive phenotypes and be employed as a potential target for gene therapy of gastric cancer. PMID:26050197

    Metastatic renal cell carcinoma (mRCC) is a challenging disease. Despite the new targeted therapies, complete remissions occur only in 1%-3% of the cases, and the most effective first-line treatment drugs have reached a ceiling in overall survival (ranging from 9 to 49 mo). Metastasectomy remains to be the only curative option in most patients with mRCC. Prognostic nomograms have been recently published, so we have tools to classify patients in risk groups, allowing us to detect the cases with the higher risk of recurrence after metastasectomy. Although sparse, there is some evidence of effectiveness of neoadjuvant targeted therapy before metastasectomy; but with an increase in surgical complications due to the effects of these new drugs in tissue healing. We have aimed to answer the question: Is there a role for systemic targeted therapy after surgical treatment for metastases of renal cell carcinoma? We have made a search in Pubmed database. As far as we know, evidence is low and it’s based in case reports and small series of patients treated with adjuvant drugs after neoadjuvant therapy plus metastasectomy in cases of partial response to initial systemic treatment. Despite the limitations and high risk of bias, promising results and cases with long-term survival with this approach have been described. Two ongoing clinical trials may answer the question that concerns us. PMID:25949939

    Background: Rhinocerebral mucormycosis occurs in immunocompromised hosts with uncontrolled diabetes, solid organ transplants, and hematologic malignancies. Primary disease is in the paranasal sinuses but often progresses intracranially, via direct extension or angioinvasion. Rhinocerebral mucormycosis is rapidly fatal with a mortality rate of 85%, even when maximally treated with surgical debridement, antifungal therapy, and correction of underlying processes. Methods: We performed a retrospective chart review of patients with rhinocerebral mucormycosis from 2011 to 2014. These patients were analyzed for symptoms, surgical and medical management, and outcome. We found four patients who were diagnosed with rhinocerebral mucormycosis. All patients underwent rapid aggressive surgical debridement and were started on antifungal therapy on the day of diagnosis. Overall, we observed a mortality rate of 50%. Results: An early aggressive multidisciplinary approach with surgical debridement, antifungal therapy, and correction of underlying disease have been shown to improve survivability in rhinocerebral mucormycosis. Conclusion: A multidisciplinary approach to rhinocerebral mucormycosis with otolaryngology, neurosurgery, and ophthalmology, infectious disease and medical intensivists can help reduce mortality in an otherwise largely fatal disease. Even despite these measures, outcomes remain poor, and a high index of suspicion must be maintained in at-risk populations, in order to rapidly execute a multifaceted approach. PMID:27280057

    Reconstruction of craniofacial congenital bone defects has historically relied on autologous bone grafts. Engineered bone using mesenchymal stem cells from the umbilical cord on electrospun nanomicrofiber scaffolds offers an alternative to current treatments. This preclinical study presents the development of a juvenile swine model with a surgically created maxillary cleft defect for future testing of tissue-engineered implants for bone generation. Five-week-old pigs (n=6) underwent surgically created maxillary (alveolar) defects to determine critical-sized defect and the quality of treatment outcomes with rib, iliac crest cancellous bone, and tissue-engineered scaffolds. Pigs were sacrificed at 1 month. Computed tomography scans were obtained at days 0 and 30, at the time of euthanasia. Histological evaluation was performed on newly formed bone within the surgical defect. A 1 cm surgically created defect healed with no treatment, the 2 cm defect did not heal. A subsequently created 1.7 cm defect, physiologically similar to a congenitally occurring alveolar cleft in humans, from the central incisor to the canine, similarly did not heal. Rib graft treatment did not incorporate into adjacent normal bone; cancellous bone and the tissue-engineered graft healed the critical-sized defect. This work establishes a juvenile swine alveolar cleft model with critical-sized defect approaching 1.7 cm. Both cancellous bone and tissue engineered graft generated bridging bone formation in the surgically created alveolar cleft defect. PMID:25837453

    Open-heart operations in patients with mucopolysaccharidoses are exceedingly rare and pose distinct clinical challenges. Few reports exist of valve replacement in type VI mucopolysaccharidosis, mostly entailing combined mitral and aortic valve replacement. Here reported is the case of a young woman with mitral and aortic valve disease, in whom the surgical procedure was confined to the aortic valve. The rationale behind this strategy, particularly in light of the benefits offered by specific enzyme replacement therapy of type VI mucopolysaccharidosis, is discussed. PMID:27343522

    2016-01-01

    Background: It has been reported that clinical results of mechanical periodontal treatment could differ between subjects and among different sites of the tooth in the patient. The objective of this multilevel analysis is to investigate clinical factors at subject and sites of the tooth that influence variations in clinical attachment (CAL) increase and probing depth (PD) diminution of adjunctive moxifloxacin (MOX) at six months post-treatment in generalized aggressive periodontitis. Methods: This clinical trial included 40 patients randomly distributed to two therapy protocols: scaling and root planing alone or combined with MOX. Multilevel linear models for continuous variables were formulated to evaluate the clinical impact of the hierarchical configuration of periodontal data. Results: Six months following therapy, the divergences between both protocols were statistically significant in PD diminution and CAL increase, favouring the MOX therapy (p<0.001). Besides, the multilevel analysis revealed that adjunctive MOX at the subject level, non-molar and the interaction non-molar x MOX at the tooth level, interproximal sites and the interaction interproximal sites x MOX at the site level, were statistically significant factors in determining CAL increase and PD diminution. Conclusions: The main cause of variability in CAL gain and PD reduction following adjunctive MOX was attributable to the tooth level. Adjunctive MOX and their interactions with non-molar and interproximal sites showed higher clinical benefits at the tooth and site levels which could be essential for PD reduction and CAL gain in generalized aggressive periodontitis subjects.

    The aim of the present randomized controlled clinical trial was to investigate the adjunctive effect of systemic antibiotics and the local use of chlorhexidine for implant surface decontamination in the surgical treatment of peri-implantitis. One hundred patients with severe peri-implantitis were recruited. Surgical therapy was performed with or without adjunctive systemic antibiotics or the local use of chlorhexidine for implant surface decontamination. Treatment outcomes were evaluated at 1 y. A binary logistic regression analysis was used to identify factors influencing the probability of treatment success, that is, probing pocket depth ≤5 mm, absence of bleeding/suppuration on probing, and no additional bone loss. Treatment success was obtained in 45% of all implants but was higher in implants with a nonmodified surface (79%) than those with a modified surface (34%). The local use of chlorhexidine had no overall effect on treatment outcomes. While adjunctive systemic antibiotics had no impact on treatment success at implants with a nonmodified surface, a positive effect on treatment success was observed at implants with a modified surface. The likelihood for treatment success using adjunctive systemic antibiotics in patients with implants with a modified surface, however, was low. As the effect of adjunctive systemic antibiotics depended on implant surface characteristics, recommendations for their use in the surgical treatment of peri-implantitis should be based on careful assessments of the targeted implant (ClinicalTrials.gov NCT01857804).

    Surgical site events, including surgical site infections (SSI), represent a major problem in general surgery. SSI are responsible of nuisance for patients, and can lead to important complications and disability, often needing prolonged postoperative stay with specific treatment and recovery in Intensive Care Units. These justify the higher costs due to SSI. Despite the growing body of evidence concerning SSI in general surgery, literature dealing with SSI after colorectal surgery is scarce, reflecting in suboptimal perception of such a relevant issue by colorectal surgeons and health authorities in Italy, though colorectal surgery is associated with higher rates of SSI. The best strategy for reducing the impact of SSI on costs of care and patients quality of life would be the development of a preventive bundle, similar to that adopted in the US through the colorectal section of the National Surgery Quality Improvement Project of the American College of Surgeons (ACS-NSQIP). This policy has been showed to significantly reduce the rates of SSI. In this scenario, incisional negative pressure wound therapy (NPWT) is likely to play a pivotal role. We herein reviewed the literature to report on the current status of preventive NPWT on surgical wounds of patients undergoing colorectal procedures with primary wound closure, suggesting evidence-based measures to reduce the impact of SSI, and to contain the costs associated with conventional NPWT devices by means of newer available technologies. Some explicative real life cases are presented. PMID:25921360

Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

    Thirty-six operations for late sequelae of radiotherapy were carried out in 31 patients from 1971 to 1986. The most frequent indications for surgery were stricture (58 percent) and fistula (29 percent). In the first 8 year period from 1971 through 1978, 13 of 14 operations were diversions (colostomy or by-pass). From 1979 through 1986, a more aggressive approach prevailed. Only 32 percent of the operations were diversions. This more aggressive strategy was accompanied by a decrease of the postoperative mortality rate from 21 percent through 1978 to 0 in the later period. The overall complication rate was 23 percent. Complications were relatively more frequent after two-layer sutured or stapled anastomoses and after resection or fistula closure without temporary colostomy. We conclude that in radiation-induced colonic and rectal lesions, diversion should be performed in patients with unproved cure of disease or tumor persistence. Resection and fistula closure can be carried out safely, and a temporary colostomy is strongly recommended.

    The present study aimed to explore surgical treatments and assess the effects based on the features of cervical spine fracture in patients with ankylosing spondylitis (AS) and to summarize the experiences in perioperative management. Retrospective analysis was performed in 25 AS patients with cervical spine fracture treated in our hospital from January 2011 to December 2013. The patients were divided according to fracture segments, including 4 cases at C4 to C5, 8 cases at C5 to C6, and 13 cases at C6 to C7. Among them, 12 belonged to I type, 5 to II type, and 8 to III type based on the improved classification method for AS cervical spine fracture. The Subaxial Cervical Spine Injury Classification score for these patients was 7.2 ± 1.3, and the assessment of their neurological function states showed 6 patients (24%) were in American Spinal Injury Association (ASIA) A grade, 1 (4%) in ASIA B grade, 3 (12%) in ASIA C grade, 12 (48%) in ASIA D grade, and 3 (12%) in ASIA E grade. Surgical methods contained simple anterior approach alone, posterior approach alone, and combined posterior-anterior or anterior-posterior approach. The average duration of patients' hospital stay was 38.6 ± 37.6, and the first surgical methods were as follows: anterior approach alone on 6 cases, posterior surgery alone on 9 cases, and combined posterior-anterior or anterior-posterior approach on 10 patients. The median segments of fixation and fusion were 4.1 ± 1.4 sections. Thirteen patients developed complications. During 2 to 36 months of postoperative follow-up, 1 patient died of respiratory failure caused by pulmonary infections 2 months after leaving hospital. At the end of the follow-up, bone graft fusion was achieved in the rest of patients, and obvious looseness or migration of internal fixation was not observed. In addition, the preoperative neurological injury in 12 patients (54.5%) was also alleviated in different levels. AS cervical spine fracture, an unstable

    We investigated if the range of efficacy of a gene-based immunotherapy of solid tumours against systemic disease could be extended when used as a neoadjuvant to surgery. Hundred percent mice whose subcutaneous tumours were surgically removed 4 days post-electroporation with GM-CSF and B7-1 plasmid were systemically resistance to tumour rechallenge. In mice bearing both subcutaneous and hepatic tumours, neoadjuvant treatment of the primary tumour resulted in significant reduction in, or elimination of, hepatic tumour growth, with a significant increase in survival, indicating that control of the primary tumour by immunotherapy was not a prerequisite for containment of systemic disease.

    Primary malignant melanoma of the oral cavity is a rare neoplasm, especially on the tongue. We report a case of mucosal melanoma at the base of the tongue, an extremely rare location (only about 30 cases have been reported in literature). The extension study doesn´t revealed distant metastatic lesions. The patient was treated by subtotal glossectomy and bilateral functional neck dissection. Tongue is one of the most difficult structures to reconstruct, because of their central role in phonation, swallowing and airway protection. The defect was reconstructed with anterolateral thigh free flap. Surgical treatment was supplemented with adjuvant immunotherapy. The post-operative period was uneventful. At present, 24 months after surgery, patient is asymptomatic, there isn´t evidence of recurrence of melanoma and he hasn´t any difficulty in swallowing or phonation. Key words:Malignant mucosal melanoma, anterolateral thigh free flap, phonation, swallowing. PMID:25593674

    In this single case study, we attempt to outline the possible effect of low-level laser therapy (LLLT) on delayed wound healing and pain in chronic dehiscent sternotomy of a diabetic individual. The methods that were employed to evaluate changes pre and post irradiation were wound photography, wound area measurement, pressure ulcer scale of healing (PUSH), and visual analogue scale (VAS) for pain. After irradiation, proliferation of healthy granulation tissue was observed with decrease in scores of PUSH for sternal dehiscence and VAS for bilateral shoulders and sternal dehiscence. We found that LLLT irradiation could be a novel method of treatment for chronic sternal dehiscence following coronary artery bypass grafting, as it augments wound healing with an early closure of the wound deficit. Hence, this might be translated into an early functional rehabilitation and decreased pain perception of an individual following surgical complication. PMID:23766600

    Hypophosphatasia (HPP) is a rare inherited disorder of bone metabolism that results in the loss of function of the gene coding for tissue-nonspecific alkaline phosphatase (TNSALP). Patients with HPP have defective bone mineralization as well as craniosynostosis that can be seen in the infantile and childhood forms of this disease. Traditionally, HPP has had a poor prognosis, with few children surviving to exhibit the phenotype of clinical craniosynostosis that requires surgical intervention. Here, the authors report on new advancements in enzyme replacement therapy (ERT) for children affected by HPP, allowing these patients to survive and undergo surgery to address complex craniosynostosis. The authors discuss their case series of 4 HPP patients treated at their institution with ERT who have undergone successful surgical intervention for craniosynostosis. These children had no complications related to their surgeries and exhibited decreased neurological symptoms following cranial vault remodeling. This study reveals that ERT administered either pre- or post- operatively paired with cranial vault remodeling strategies can yield improved neurological outcomes in children affected by HPP.

    The study was aimed to evaluate the usefulness of the quantitative cerebral perfusion reserve SPECT for the prognosis in patients with critical stenoses of the internal carotid arteries treated surgically or rheotherapeutically. 23 patients with angiographically verified mono (n=12) or bilateral (n=11) stenosis of the internal carotid artery for more than 75% and with recent (>30 days) minor stroke or TIA events in anamnesis were referred for the study. 6 age-matched healthy persons served as controls. In everybody the cerebral perfusion reserve was studied by using of the local cerebral blood volume to cerebral blood flow (rCBV/rCBF, sec) index using a double isotope technique which combined Tl-199 diethyidithiocarbamate (Tl-199-DDC) SPECT with Tc-99m red blood cells (Tc-99m-RBC) SPECT. 12 patients underwent carotid endartherectomy and 11 were treated rheotherapeutically by nonselective plasma substitution (5 times x 400 ml, >1800 nil in total). Patients were studied twicely: before and 10 days after the treatment, and then followed-up neurologically in the course of 1 year. Patients who had regional rCBV/rCBF index increased in the stenosed a.carotis int. - dependent region before treatment (normal value 5.2, sd 0.2 sec) have got it significantly decreased after intervention both in surgical group (from 7.1, sd 0.4 sec, down to 5.3, sd 0.3 sec, p<0.01 n=7) and in rheotherapeutical one (from 7.3, sd 0.5 sec, to 5.9, sd 0.4 sec, p<0.02 n=8). In everybody who expressed the rCBV/rCBF decreased below 5.6 sec after intervention there were no cerebrovascular ischemic events observed in the course of 12 months after carotid surgery and during 5 months in patients treated by plasmapheresis. We conclude that rCBV/rCBF SPECT index gives an independent prognostic information useful for both rheologic and surgical treatment of cerebrovascular disease; and that plasmapheresis suppress the short-term rise of cerebral ischemic events, which effect is predictable by SPECT.

    Over the past decades, the incidence of differentiated thyroid carcinoma (DTC) has steadily increased, with especially a growing number of low-risk patients. Whereas DTC used to be treated rather aggressively, it is now acknowledged that aggressive treatment does not affect outcome for low-risk patients and that it can induce adverse effects. In this review an overview of the most clinically relevant adverse effects of radioiodine treatment and thyroid hormone suppression therapy (THST) is presented, and the trend toward less aggressive treatment for low-risk patients is outlined. Salivary gland dysfunction occurs in roughly 30% of patients, and is probably due to the concentration of radioiodine in the salivary glands by the sodium/iodide symporter. Beta radiation from radioiodine can result in sialoadenitis and eventually fibrosis and loss of salivary function. Furthermore, patients can experience bone marrow dysfunction following radioiodine treatment. Although this is in general subclinical and transient, patients that receive very high cumulative radioiodine doses may be at risk for more severe bone marrow dysfunction. THST can induce adverse cardiovascular effects in patients with DTC, such as diastolic and systolic dysfunction, and also adverse vascular and prothrombotic effects have been described. Finally, the effects of THST on bone formation and resorption are outlined; especially postmenopausal women with DTC on THST seem to be at risk of bone loss. In the past years, advances have been made in preventing low-risk patients from being overtreated. Improved biomarkers are still needed to further optimize risk stratification and personalize medicine. PMID:26279993

This review will focus on the corneal-based surgical options to address presbyopia including various types of corneal intrastromal inlays and laser ablation techniques to generate either a multifocal cornea (“PresbyLASIK”) or monovision. The natural history of presbyopia develops prior to cataracts, and these presbyopic surgeries have been largely studied in phakic patients. Nevertheless, pseudophakic patients may also undergo these presbyopia-compensating procedures for enhanced quality of life. This review examines the published reports that apply these technologies to patients after cataract surgery and discusses unique considerations for this population. PMID:27051527

    IL-18 has a potential to up-regulate the Th1 and Th2 immune responses. It is known that IL-18, in synergy with IL-12, augments the Th1 response to bacterial infections, but it also augments the Th2 response to allergic disorders in the absence of IL-12. Although the Th1 and Th2 immune responses cross-regulate each other, our recent murine studies have demonstrated that multiple, alternate-day IL-18 injections (but not a single injection) could augment not only the Th1 immune response but also the Th2 immune response, including IgM production against bacterial infection in mice. In addition, critically ill patients who suffer from severe surgical stresses, e.g., trauma injury, burn injury, and major surgery, are known to be highly susceptible to bacterial infections/sepsis, and their outcomes become extremely poor as a result of infectious complications. Their host defense systems against infections, such as Th1-mediated cellular immunity, Th2-mediated humoral immunity, and neutrophil-mediated immunity, are impaired severely and multifactorially. Although simultaneous enhancement of these immune responses may be ideal for such immunocompromised patients, its achievement appears to be difficult because of the cross-regulating effect of the Th1 and Th2 responses. However, multiple IL-18 injections into mice can effectively restore these impaired immune responses in the immunocompromised mice receiving severe burn injury or splenectomy, thus improving their survival after bacterial infections. Therefore, IL-18 treatment may be an attractive and useful therapeutic tool against bacterial complications in immunocompromised hosts after severe surgical stress. PMID:23407120

    Introduction Bone infections after trauma, i.e. posttraumatic osteomyelitis, pose one of the biggest problems of orthopedic surgery. Even after sufficient clinical therapy including vast debridement of infected bone and antibiotic treatment, regeneration of postinfectious bone seems to be restricted. One explanation includes the large sized defects resulting from sufficient debridement. Furthermore, it remains unclear if inflammatory processes after bone infection do affect bone regeneration. For continuing studies in this field, an animal model is needed where bone regeneration after sufficient treatment can be studied in detail. Methods For this purpose we created a stable infection in murine tibiae by Staphylococcus aureus inoculation. Thereafter, osteomyelitic bones were debrided thoroughly and animals were subsequently treated with antibiotics. Controls included debrided, non-infected, as well as infected animals exclusively treated with antibiotics. To verify sufficient treatment of infected bone, different assessments detecting S. aureus were utilized: agar plates, histology and RT-qPCR. Results All three detection methods revealed massive reduction or eradication of S. aureus within debrided bones 1 and 2 weeks postoperatively, whereas sole antibiotic therapy could not provide sufficient treatment of osteomyelitic bones. Debrided, previously infected bones showed significantly decreased bone formation, compared to debrided, non-infected controls. Discussion Thus, the animal model presented herein provides a reliable and fascinating tool to study posttraumatic osteomyelitis for clinical therapies. PMID:26872128

    Background: Gingival bleeding is considered as an important clinical sign for diagnosis of periodontal disease pathogenesis. Immune inflammatory reactions caused by local factors are considered as essential reasons for gingival bleeding, as also for the systemic bleeding disorders. In disease-free conditions of gingiva, the bleeding disorders are considered to be the main contender for bleeding. Other than these variables, many systemic drugs including systemic aspirin could also cause gingival bleeding. The main aim of the study was to evaluate the effect of buffered aspirin therapy on gingival bleeding. Materials and Methods: Totally, 36 systemically healthy individuals were included in the 15-day randomized, double-blinded, placebo-controlled clinical trial. The 15 days were divided as: control period for the first 7 days and study period for the following 7 days. On the 1st day, all individuals were given oral prophylaxis after recording gingival parameters such as Plaque Index, probing depth, and Bleeding Index, and then blood samples were collected for hematological investigations. Then, all individuals were administered placebo capsules for 1 week as once daily dose. On the 8th day, all procedures were repeated and the individuals were prescribed with 325 coated aspirin capsules for 1 week. On the 15th day, all parameters were repeated and the results were statistically analyzed. Results: In the study period, the parameters such as Bleeding Index, bleeding time, and prothrombin time were increased significantly, compared to the control period. Conclusion: The variables such as systemic drug therapy should be considered for the examination of gingiva while the diagnosis is considered mainly based on gingival bleeding. PMID:23066256

    Recent preclinical and clinical data have suggested the potential benefit of photodynamic therapy (PDT) in the treatment of periodontitis. However, currently, there are very limited data from controlled clinical trials evaluating the effect of PDT in the treatment of periodontitis. The aim of the present study was to evaluate the clinical and microbiological effects of the adjunctive use of PDT in non-surgical periodontal treatment in patients receiving supportive periodontal therapy. Twenty-four patients receiving regularly supportive periodontal therapy were randomly treated with either subgingival scaling and root planing followed by a single episode of PDT (test) or subgingival scaling and root planing alone (control). The following parameters were evaluated at baseline and at 3 months and 6 months after therapy: full mouth plaque score (FMPS), full mouth bleeding score (FMBS), bleeding on probing (BOP) at experimental sites, probing pocket depth (PPD), gingival recession (REC), and clinical attachment level (CAL). Primary outcome variables were changes in PPD and CAL. Microbiological evaluation of Aggregatibacter actinomycetemcomitans (A.a.), Porphyromonas gingivalis (P.g.), Prevotella intermedia (P.i.), Tannerella forsythensis (T.f.), Treponema denticola (T.d.), Peptostreptococcus micros (P.m.), Fusobacterium nucleatum (F.n.), Campylobacter rectus (C.r.), Eubacterium nodatum (E.n.), Eikenella corrodens (E.c.), and Capnocytophaga species (C.s.) was also performed at baseline and at 3 months and 6 months after therapy, using a commercially available polymerase chain reaction test. No differences in any of the investigated parameters were observed at baseline between the two groups. At 3 months and 6 months after treatment, there were no statistically significant differences between the groups in terms of PPD, CAL and FMPS. At 3 months and 6 months, a statistically significantly higher improvement of BOP was found in the test group. At 3 months after therapy

    Thymoma is a rare neoplasm usually with an indolent growth pattern; however, local invasion and/or dissemination may occur. Surgery has been the standard of care for early stage disease with good to excellent cure rates anticipated. This neoplasm has been found to be relatively sensitive to cisplatinum-based chemotherapy as compared with most other epithelial tumors. Aggressive multimodality therapy therefore can result in long-term disease-free survival for patients presenting with locally advanced or even disseminated disease. This chapter outlines the current medical and surgical treatment options for thymoma. PMID:15229793

    Purpose: Although positive surgical margins are generally associated with a higher risk of local-regional recurrence (LRR) for most solid tumors, their significance after mastectomy remains unclear. We sought to clarify the influence of the mastectomy margin on the risk of LRR. Methods and Materials: The retrospective cohort consisted of 397 women who underwent mastectomy and no radiation for newly diagnosed invasive breast cancer from 1998-2005. Time to isolated LRR and time to distant metastasis (DM) were evaluated by use of cumulative-incidence analysis and competing-risks regression analysis. DM was considered a competing event for analysis of isolated LRR. Results: The median follow-up was 6.7 years (range, 0.5-12.8 years). The superficial margin was positive in 41 patients (10%) and close ({<=}2 mm) in 56 (14%). The deep margin was positive in 23 patients (6%) and close in 34 (9%). The 5-year LRR and DM rates for all patients were 2.4% (95% confidence interval, 0.9-4.0) and 3.5% (95% confidence interval, 1.6-5.3) respectively. Fourteen patients had an LRR. Margin status was significantly associated with time to isolated LRR (P=.04); patients with positive margins had a 5-year LRR of 6.2%, whereas patients with close margins and negative margins had 5-year LRRs of 1.5% and 1.9%, respectively. On univariate analysis, positive margins, positive nodes, lymphovascular invasion, grade 3 histology, and triple-negative subtype were associated with significantly higher rates of LRR. When these factors were included in a multivariate analysis, only positive margins and triple-negative subtype were associated with the risk of LRR. Conclusions: Patients with positive mastectomy margins had a significantly higher rate of LRR than those with a close or negative margin. However, the absolute risk of LRR in patients with a positive surgical margin in this series was low, and therefore the benefit of postmastectomy radiation in this population with otherwise favorable

    Wide local excision is considered routine therapy after initial diagnosis of primary melanoma to reduce local recurrences, but it does not impact survival. Sentinel node staging is recommended for melanomas of intermediate thickness, but it has also not demonstrated any indisputable therapeutic effect on survival. The prognostic value of sentinel node staging has been long established and is therefore considered routine, especially in light of the eligibility criteria for adjuvant therapy (trials). Whether completion lymph node dissection after a positive sentinel node biopsy improves survival is the question of current trials. The MSLT-2 study is best powered to show a potential benefit, but it has not yet reported any data. Another study, the German DECOG study, presented at the 2015 American Society of Clinical Oncology (ASCO) Annual Meeting did not show any benefit but is criticized for the underpowered design and insufficient follow-up. There is no consensus on the use of adjuvant interferon in melanoma. This topic has been the focus of many studies with different regimens (low-, intermediate-, or high-dose and/or short- or long-term treatment). Adjuvant interferon has been shown to improve relapse-free survival but failed to improve overall survival. More recently, adjuvant ipilimumab has also demonstrated an improved relapse-free survival. Overall survival data have not yet been reported due to insufficient follow-up. Currently, studies are ongoing to analyze the use of adjuvant anti-PD-1 and molecular targeted therapies (vemurafenib, dabrafenib, and trametinib). In the absence of unambiguously positive approved agents, clinical trial participation remains a priority. This could change in the near future. PMID:27249760

    The treatment of idiopathic scoliosis over 40 degrees (Cobb) during the growth period is under discussion concerning the indication for conservative or surgical treatment. Curve progression depends on the degree of the frontal and sagittal deformity, vertebral rotation, rigidity of the curve, the skeletal age, the age and sex of the patient, the familial frequency of scoliosis and the location of the curve. In scoliosis over 40 degrees progression is fast and the possibilities for successful conservative brace treatment are reduced during the growth period. Progression occurs more frequently in thoracic and double major scolioses, especially in young patients (Risser sign 0 and 1). Predictive factors of a successful brace treatment are the correction of scoliosis and rotation; deterioration of both during the brace treatment leads to poor results. Evaluating the flexibility of the sagittal profile is important, as is primary correction of 30-50% in the brace during the 3 months. Operative correction of small primary curves reduces the fusion length, operation time, and blood loss and is followed by a reduction in loading on the adjacent vertebral segments in comparison to the long fusions necessary in more structural and double major scolioses. So far it is not possible to make an equivalent judgment of the frequency of the "crankshaft" phenomenon and the treatment necessary in young patients (Rissersign 0 and 1) treated by dorsal instrumentation alone, but temporary brace treatment may be considered in those cases.

    Background: The major goal of non-surgical periodontal therapy is to reduce or eliminate the subgingival pathogenic microbial flora that is known to be associated with volatile sulfur compounds (VSC). Aim: The aim of this study was, therefore, to determine the effect of non-surgical periodontal therapy on the concentration of VSC in mouth air of young adults. Subjects and Methods: Four hundred subjects, grouped into two based on the absence or presence of periodontal diseases, were involved in this study. Basic periodontal examination was used for the grouping. The measurement of the concentration of the VSC in the mouth air of the subjects was done objectively, using the Halimeter, before and after the therapy, and at recall visits 2 weeks and 6 weeks after therapy. Chi-square and Paired t-test were used to find statistical significance. Results: The results revealed that at baseline, 78.7% (48/61) of the subjects who had VSC concentration more than 250 parts per billion (ppb) were from the group with periodontal disease. Immediately after non-surgical periodontal therapy, only 8.5% (17/200) of the subjects with periodontal disease had VSC concentration of more than 250 ppb while all the subjects with no periodontal disease had VSC concentration less than 181 ppb. The same pattern of reduction in the concentration of the VSC and improvement in oral hygiene was also obtained 2 weeks and 6 weeks after therapy. Conclusion: It can be concluded that non-surgical periodontal therapy brought about reduction in the concentration of volatile sulfur compounds in mouth air of young adults. PMID:24116328

    Trauma during dental surgery is a predisposing factor for medication-related osteonecrosis of the jaws (MRONJ). There are no specific guidelines for the management of dental extractions in patients under bisphosphonate therapy (BPT). The authors proposed in 2013 a successful protocol for tooth extractions in patients under BPT supported by Nd:YAG low-level laser therapy (LLLT). The aim of this study was to validate the safety and efficacy of this protocol reporting the data related to its application in a particular category of patients under BPT at high risk for MRONJ and who were previously affected with MRONJ. Eighty-two tooth extractions were performed in 36 patients previously affected with MRONJ. Antibiotic treatment was administered 3 days before and 2 weeks after tooth extractions. Patients were additionally treated with Nd:YAG LLLT, 5 applications of 1 minute each. Patients were evaluated 3 days and once a week for 2 months after the extractions and every time they received LLLT. In a total of 82 extractions, minimal bone exposure was observed in 2 cases, treated with Er:YAG laser vaporization and then completely healed. The data confirmed that laser biostimulation is a reliable technique that can be considered in the surgical protocol for patients under BPT. PMID:25915674

    The optimal treatment of patients with craniopharyngioma remains controversial. In particular, the role of aggressive treatment compared to less aggressive therapeutic options is poorly understood. Radical resection is the therapy of choice at any age, because it is associated with the best outcome in terms of survival. Nevertheless, aggressive behaviour, location, involvement of critical structures, tumour size, calcifications, and patient age may limit the extent of resection. Surgery can also carry significant morbidity in terms of visual, hypothalamic, and endocrinological disturbances. Long term sequelae reduce the quality of life in 50% of long-term survivors, notably obesity and neurobehavioral impairment due to hypthalamic involvement and iatrogenic induced lesions. The quality of life should be considered as a clinically important endpoint in patients, who currently experience good overall survival rates, regardless of the degree of surgical resection. Tendency to recur despite negative postoperative imaging led many authors to advocate a less aggressive surgical treatment followed by radiation therapy. We review the data reported in the literature, especially early outcome after surgical treatment and factors affecting the risk of tumour recurrence, to elucidate the role of attempted radical resection in the treatment of craniopharyngioma and to identify the clinical and morphological characteristics predictive for the best surgical prognosis.

    PURPOSE Patients with advanced hepatocellular carcinoma (HCC) have limited effective therapeutic options. Given the rapid advanced in drug development and emergence of novel agents, we analyzed the characteristics and outcomes of HCC patients treated on early phase trials with an emphasis on targeted therapies. METHODS We reviewed the records of consecutive HCC patients evaluated in the Phase I Clinical Trials Program at MD Anderson from March 2004. RESULTS Thirty-nine patients were not treated due to poor performance status (n = 22, 56%) and decision to pursue alternate therapies (n = 10, 27%). Of 61 treated patients (median age, 60 years; median prior therapies, 3), eight patients (13%) attained stable disease lasting ≥6 months; four (7%) had a partial response, mainly with anti-angiogenic or multikinase inhibitors. Median Phase I progression-free survival (PFS) was 2.6 months versus 4.4 months (p 0.019) and 4.1 months (p 0.27) for their first-, and second-line FDA-approved therapy. Molecular analysis showed frequent PTEN loss (10/19 patients, 53%) and P53 mutation (4/4 patients tested). On multivariate analysis, independent factors predicting shorter survival were white ethnicity/race (p 0.031), cirrhosis (p 0.016), and serum sodium (p 0.0013). CONCLUSIONS In our heavily-pretreated HCC patients, the phase I PFS was comparable to that of 2nd-line therapy, highlighting a potential role for clinical trials after progression on first-line therapy. The response rate (SD>6 months/PR) of 20% was observed with early signals of activity in regimens combining inhibitors of angiogenesis, multiple kinases and mTOR with preliminary molecular analysis revealing prevalence of PTEN loss.

    A diabetic foot or Charcot foot diagnosed in time can reduce a lot of problems for the patient, lessen high medical expense, and last but not least prevent an amputation. Good treatment options of the diabetic foot result from new technologies in wound management, angioplastic vessel improvement and optimised orthopaedic aids. Nevertheless it stays a challenging issue for practitioners and medical and health care as well as hospital owners to master this problem which will be even growing in the long run. This article intends to raise the awareness for the diabetic foot and the neuropathic osteoarthropathy, and furthermore illustrate diagnostic steps and offer therapeutic options. After distinguishing the diabetic foot from the Charcot foot a selective therapy for each entity has to be initiated. An interdisciplinary approach of specialists in dermatology, radiology, orthopaedic and internal medicine, plastic surgery and orthopaedic shoemaking is essential for a good therapeutic monitoring in order to avoid the amputation of the lower leg.

    Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of local recurrence, though the benefit of postoperative radiation therapy (RT) has not been established. In this study of grossly resected ACC, we compare local control of patients treated with surgery followed by adjuvant RT to a matched cohort treated with surgery alone. Methods and Materials: We retrospectively identified patients with localized disease who underwent R0 or R1 resection followed by adjuvant RT. Only patients treated with RT at our institution were included. Matching to surgical controls was on the basis of stage, surgical margin status, tumor grade, and adjuvant mitotane. Results: From 1991 to 2011, 360 ACC patients were evaluated for ACC at the University of Michigan (Ann Arbor, MI). Twenty patients with localized disease received postoperative adjuvant RT. These were matched to 20 controls. There were no statistically significant differences between the groups with regard to stage, margins, grade, or mitotane. Median RT dose was 55 Gy (range, 45-60 Gy). Median follow-up was 34 months. Local recurrence occurred in 1 patient treated with RT, compared with 12 patients not treated with RT (P=.0005; hazard ratio [HR] 12.59; 95% confidence interval [CI] 1.62-97.88). However, recurrence-free survival was no different between the groups (P=.17; HR 1.52; 95% CI 0.67-3.45). Overall survival was also not significantly different (P=.13; HR 1.97; 95% CI 0.57-6.77), with 4 deaths in the RT group compared with 9 in the control group. Conclusions: Postoperative RT significantly improved local control compared with the use of surgery alone in this case-matched cohort analysis of grossly resected ACC patients. Although this retrospective series represents the largest study to date on adjuvant RT for ACC, its findings need to be prospectively confirmed.

    Purpose: The application of incisional negative pressure wound therapy (INPWT) to clean, closed surgical incisions is a growing clinical practice. A systematic review was conducted to evaluate the effect of INPWT on surgical sites healing by primary intention. The primary outcomes of interest are incidence of complications (infection, dehiscence, seroma, hematoma, skin necrosis, or blistering). Methods: Two independent reviewers performed a search of the Ovid MEDLINE and EMBASE databases from 2006 to 2012 for published articles. Supplemental searches were performed using reference lists and conference proceedings. Studies were selected for inclusion based on predetermined inclusion and exclusion criteria. Data extraction regarding study quality, demographic and clinical characteristics, and outcomes was performed independently, and data on the incidence of infection was combined using a fixed-effects meta-analysis model. Results: Ten (5 randomized controlled trials and 5 observational) studies were included, which investigated the outcomes of 626 incisions on 610 patients. Six studies compared INPWT with sterile dry dressings (SDDs). The literature shows a significant decrease in rates of infection when using INPWT. Results on dehiscence do show a decrease in some studies, but results are inconsistent to make a conclusion. Because of limited studies, it is difficult to make any assertions on seroma, hematoma, and skin necrosis. Conclusions: This systematic review shows possible evidence of a decrease in the incidence of infection with application of INPWT. Looking at other variables such as dehiscence, seroma, hematoma, and skin necrosis show no consistent data and suggest further studies in order for proper recommendations for INPWT. PMID:24106562

    Prior to non-surgical therapy of gallstones it is important to assess their number and size. In order to evaluate the accuracy of ultrasound (US) and oral cholecystography (OCG) in counting and measuring gallstones, a prospective blind study was conducted to compare the results of US (n = 99) and OCG (n = 36), either alone or in combination (n = 34), with the number and size of gallstones retrieved after cholecystectomy. The number of gallstones was accurately estimated by US and OCG in 74% and 69% of the cases, respectively. In assessing the presence of up to three, five or 10 gallstones both US and OCG proved reliable. In measuring the size of gallstones, there was 19% accuracy with US compared with only 3% with OCG. With an accepted measurement error of 3 mm these values increased to 80% for US and 44% for OCG. US proved more reliable than OCG in discriminating gallstones smaller or larger than 10 mm and smaller or larger than 20 mm, but with US, detection of gallstones larger than 30 mm was problematic. Both US and OCG underestimated gallstone size. The combination of both techniques did not significantly improve the assessment of either number or size of gallstones compared with the results obtained with US or OCG alone. It is concluded that (1) both US and OCG have some limitations in assessing the number and size of gallstones, (2) the combination of both examinations does not improve accuracy, and (3) patient selection for non-surgical treatment of gallstones can be started by US alone.

    Purpose: To examine the association between hospital surgical volume and the use of radiation therapy (RT) after breast-conserving surgery (BCS) in Taiwan. Methods and Materials: We used claims data from the National Health Insurance program in Taiwan (1997-2005) in this retrospective population-based study. We identified patients with breast cancer, receipt of BCS, use of radiation, and the factors that could potentially associated with the use of RT from enrollment records, and the ICD-9 and billing codes in claims. We conducted logistic regression to examine factors associated with RT use after BCS, and performed subgroup analyses to examine whether the association differs by medical center status or hospital volumes. Results: Among 5,094 patients with newly diagnosed invasive breast cancer who underwent BCS, the rate of RT was significantly lower in low-volume hospitals (74% vs. 82%, p < 0.01). Patients treated in low-volume hospitals were less likely to receive RT after BCS (odds ratio = 0.72, 95% confidence interval = 0.62-0.83). In addition, patients treated after the implementation of the voluntary pay-for-performance policy in 2001 were more likely to receive RT (odds ratio = 1.23; 95% confidence interval = 1.05-1.45). Subgroup analyses indicated that the high-volume effect was limited to hospitals accredited as non-medical centers, and that the effect of the pay-for-performance policy was most pronounced among low-volume hospitals. Conclusions: Using population-based data from Taiwan, our study concluded that hospital surgical volume and pay-for-performance policy are positively associated with RT use after BCS.

    Eradication of residual malignancies and metastatic tumors via a systemic approach is the key for successfully treating cancer and increasing the cancer patient survival. Systemic administration of IL12 protein in an acute large dose is effective but toxic. Systemic administration of IL12 gene by persistently expressing a low level of IL12 protein may reduce the systemic toxicity, but only eradicates IL12 sensitive tumors. Here, we discovered that sequential administration of IL12 and IL27 encoding DNA, referred to as sequential IL12-IL27 gene therapy, not only eradicated IL12 sensitive tumors from 100% of mice but also eradicated the highly malignant 4T1 tumors from 33% of treated mice in multiple independent experiments. This IL12-IL27 sequential gene therapy is not only superior to IL12-IL12 sequential gene therapy for eliminating tumors, but also for inducing CTL activity, increasing T cell infiltration into tumors, and yielding a large number of tumor-specific IFNγ positive CD8 T cells. Notably, depletion of either T- or NK-cells during the IL27 treatment phase reverses tumor eradication, suggesting an NK-cell requirement for this sequential gene therapy-mediated tumor eradication. Both reversal of the administration sequence and co-administration of IL12 and IL27 impaired the tumor eradication in 4T1 tumor bearing mice. This IL12-IL27 sequential gene therapy, via sequential administration of IL12 and IL27 encoding plasmid DNA into tumor-bearing mice through intramuscular electroporation, provides a simple but effective approach for eliminating inaccessible residual tumors.

    Prognosis is poor for patients with biologically aggressive Non-Hodgkin lymphoma (NHL), refractory to chemotherapy or relapsed after autologous transplantation, especially when no disease control before allogeneic transplantation is achieved. In 16 patients (median age 53, median prior regimes 5) with relapsed or refractory non-remission NHL, we analysed retrospectively the efficacy of a sequential therapy comprising clofarabine re-induction followed by a reduced-intensity conditioning with fludarabine, CY and melphalan, and T-cell-replete HLA-haploidentical transplantation. High-dose CY was utilized post-transplantation. All patients engrafted. Early response (day +30) was achieved in 94%. Treatment-related grade III-IV toxicity occurred in 56%, most commonly transient elevation of transaminases (36%), while there was a low incidence of infections (19% CMV reactivation, 19% invasive fungal infection) and GVHD (GVHD: acute III-IV: 6%; mild chronic: 25%). One-year non-relapse mortality was 19%. After a median follow-up of 21 months, estimated 1- and 2-year PFS was 56 and 50%, respectively, with 11 patients (69%) still alive after 2 years. In summary, sequential therapy is feasible and effective and provides an acceptable toxicity profile in high-risk non-remission NHL. Presumably, cytotoxic reinduction with clofarabine provides enough remission time for the graft-versus lymphoma effect of HLA-haploidentical transplantation to kick in, even in lymphomas that are otherwise chemo-refractory.

    Introduction: Clinically benign prostatic hyperplasia (BPH) is classically associated by the progressive development of lower urinary tract symptoms (LUTS). The incidence of bothersome LUTS is associated with age and may vary in patients over 50 years old. In many developing countries with an aging population, BPH associated with LUTS has become a major health issue. To optimize quality of care and control of cost, there is an imperative need to examine the pattern of BPH management. The goal of this study is to capture the Canadian trend in surgical management of BPH and the use of laser therapy during the last 5 years from 2007–2008 to 2011–2012. Methods: We collected the number of transurethral resection of the prostate (TURP) procedures performed in each province in Canada from the Canadian Institute for Health Information (CIHI) reports for the fiscal years (April 1st–March 31st) of 2007–2008, 2008–2009, 2009–2010, 2010–2011 and 2011–2012. Results: Overall, the total number of TURP procedures remained stable from 20 294 procedures per year in 2007 to 20 629 in 2011. In terms of distribution according to provinces, in 2011, about 40% of procedures were performed in Ontario, 20% in BC, 18 in Quebec and 8% in Alberta. These proportions between provinces have remained similar and stable between 2007 and 2011. In contrast, the number of alternative minimally invasive procedures has slowly grown from 767 interventions in 2007 to 1559 in 2011. Overall, laser procedures represented 7.6% of the total number of BPH surgeries in Canada in 2011. The contribution of laser therapy to the amount of total BPH procedures largely varied between provinces. Conclusions: The use of minimally invasive laser procedure alternatives to TURP is progressively growing. Among the novel laser therapies, HoLEP and GreenLight vaporization are the only procedures that have demonstrated equivalent outcomes compared to TURP in randomized clinical trials. Furthermore, due to

    aim of this study was to evaluate the efficacy of periodontal scaling and oral hygiene instruction for patients with mild chronic periodontitis and rheumatoid arthritis through clinical periodontal parameters and laboratory tests for CRP (C- reactive protein) and ESR (erythrocyte sedimentation rate). Twelve individuals with rheumatoid arthritis and 12 healthy individuals were evaluated, with a mean age of 45.38 and 46.75 respectively, all female and with mild, chronic periodontitis. The participants were evaluated clinically and periapical radiographs were taken (T1), after which periodontal treatment was instituted. After ninety days (T2), new clinical and laboratory data were obtained. Probing depth, bleeding index, and plaque indexes were observed in both groups, and the results demonstrated reductions but no statistical differences. Laboratory tests for CRP and ESR produced higher values for the rheumatoid arthritis group with T1- T2 reductions on the average, but the values were still higher than in the health group. We conclude that periodontal therapy in patients with rheumatoid arthritis and mild chronic periodontitis showed a improvement in the periodontal clinical parameters and laboratory tests that were evaluated.

    With currently available combination chemotherapy regimens, the outcome of the patients newly diagnosed with aggressive non-Hodgkin's lymphoma (NHL) identified as 'high' and 'high-intermediate' risk groups according to the international prognostic index (IPI) is still unsatisfactory and a more innovative therapy is urgently required to improve the survival of the patients. The purpose of this study was to compare the efficacy of rituximab given in combination with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and ESHAP (etoposide, methylprednisolone, high-dose Ara-C, cisplatin) vs CHOP-ESHAP and upfront high-dose therapy (HDT) and autologous stem cell transplantation (ASCT) vs standard CHOP in patients aged < or = 65 years old newly diagnosed with 'high' and 'high-intermediate' risk aggressive lymphoma enrolled onto two consecutive treatment trials at the institute. Between May 1995 - July 2002, 84 patients, aged 15 - 65 years old, with newly diagnosed aggressive NHL and an age-adjusted IPI of 2 or 3 were enrolled. The median age of the patients was 38 years (range 15 - 65). The baseline demographic features, in particular the major prognostic variables, were similar between the treatment groups. Patients treated with rituximab-CHOP-ESHAP received eight cycles of rituximab (375 mg m(-2) on day 1 of cycles 1 - 6 and days 21 and 28 of cycle 7) plus CHOP (day 3 of cycles 1, 3 and 5) and ESHAP (day 3 of cycles 2, 4 and 6 and day 1 of cycle 7) at 21-day intervals. Patients enrolled onto the CHOP-ESHAP-HDT arm (n = 23) were treated with three courses of CHOP and then switched to two or four cycles of ESHAP followed by HDT. Patients treated with CHOP alone (n = 25) were treated with the standard eight cycles of CHOP. The rate of complete remission was significantly improved with rituximab-CHOP-ESHAP compared with either CHOP-ESHAP-HDT or CHOP alone (67% compared with 44% and 36%, respectively; p = 0.043).

    Background Closed incisional wound surgery frequently leaves dead space under the repaired skin, which results in delayed healing. The purpose of this study was to evaluate the effect of negative pressure wound therapy (NPWT) on incisional wounds with dead space after primary closure by evaluating the fluid volume through the suction drain, blood flow of the skin, tensile strength, and histology of the wounds. Methods Bilateral 25-cm-long incisional wounds with dead space were created on the back of 6 pigs by partially removing the back muscle and then suturing the skin with nylon sutures. NPWT (experimental group) or gauze dressing (control group) was applied over the closed incision for 7 days. Analysis of the wound included monitoring the amount of closed suction drain, blood perfusion unit, tensile strength of the repaired skin, and histology of the incision site. Results The drainage amount was significantly reduced in the experimental group (49.8 mL) compared to the control group (86.2 mL) (P = 0.046). Skin perfusion was increased in the experimental group with statistical significance compared to the control group (P = 0.0175). Collagen staining was increased in the experimental group. The tensile strength of the incision site was significantly higher in the experimental group (24.6 N at 7 days, 61.67 N at 21 days) compared to the control group (18.26 N at 7 days, 50.05 N at 21 days) (P = 0.02). Conclusion This study explains some of the mechanism for using NPWT in closed incision wounds with dead space. It demonstrates that NPWT significantly reduces drainage amount, increases skin perfusion, increases tensile strength, and has the tendency to promote collagen synthesis for closed wound with dead space indicating enhanced healing.

    Introduction: Periodontitis is a chronic inflammatory disease due to exposition to plaque and tartar. Conventional treatments consist of scaling and root planing (SRP) and antibiotics administration. Among them encouraging results have been obtained using alternative protocols, like the antimicrobial photodynamic therapy (PDT). Aim of the Study: Evaluation of PDT effects added to conventional methods. Materials and Methods: 11 patients (4M/7F, 37-67 years aged, non-smoking) affected by untreated chronic periodontal disease, with >3mm pockets in at least 4 teeth were divided in two groups, test and control group. Each patient had to made full-intraoral before and after the treatment. The test group received SRP+PDT, while the control group was subjected to SRP. The PDT was performed through the HELBO®TheraLite (Bredent Medical), diode laser battery powered 670nm with an output of 75mW/cm2. The Helbo Blue photosensitizer, containing methylene blue, was used. The exposure time to the laser effect was of 10'' for each site, for a total of 60'' at 3J/cm2. Results: Both groups had a significant improvement in the reduction of pocket depth (PD), above all in the test group. Statistical analysis was performed through the T-test, evaluating PD between the two groups p=0.96 (p> 0.05), resulting not statistically significant. Conclusion: PDT is a promising support to SRP, achieving a significant reduction in the pocket depth, but more cases are needed to confirm the validity of the used protocol.

    Introduction. Aggressive angiomyxoma is a rare mesenchymal neoplasm. Although benign in the majority of the cases, these neoplasms usually present a locally infiltrative nature and high rates of recurrence. Due to its rarity, misdiagnosis is a common problem. Case Presentation. We present one case of aggressive angiomyxoma in a 25-year-old pregnant woman. The patient presented with a large vaginal mass that was interpreted as a vaginal cyst. We performed surgical resection of the neoplasm and the correct diagnosis was only achieved after histological examination. With this case, we highlight the importance of considering this diagnosis in patients with genital and perineal masses of unknown origin and the impact of a correct preoperative diagnosis in patient's management and follow-up. Conclusion. Although aggressive angiomyxoma is rare, it should be considered in differential diagnosis of pelviperineal masses in young women. Its positivity to estrogen and progesterone receptors can justify enlargement and recurrence during pregnancy, although few cases are reported. Early recognition demands high index of suspicion for both gynaecologists and pathologists. Wide surgical excision with tumor free margins is the basis of curative treatment. Adjuvant therapy may be necessary for residual or recurrent tumors. Long-term follow-up is recommended. PMID:27274877

    Obese women undergoing caesarean section (CS) are at increased risk of surgical site infection (SSI). Negative Pressure Wound Therapy (NPWT) is growing in use as a prophylactic approach to prevent wound complications such as SSI, yet there is little evidence of its benefits. This pilot randomized controlled trial (RCT) assessed the effect of NPWT on SSI and other wound complications in obese women undergoing elective caesarean sections (CS) and also the feasibility of conducting a definitive trial. Ninety-two obese women undergoing elective CS were randomized in theatre via a central web based system using a parallel 1:1 process to two groups i.e., 46 women received the intervention (NPWT PICO™ dressing) and 46 women received standard care (Comfeel Plus® dressing). All women received the intended dressing following wound closure. The relative risk of SSI in the intervention group was 0.81 (95% CI 0.38–1.68); for the number of complications excluding SSI it was 0.98 (95% CI 0.34–2.79). A sample size of 784 (392 per group) would be required to find a statistically significant difference in SSI between the two groups with 90% power. These results demonstrate that a larger definitive trial is feasible and that careful planning and site selection is critical to the success of the overall study.

  14. Buschke-Löwenstein tumor with squamous cell carcinoma treated with chemo-radiation therapy and local surgical excision: report of three cases

    PubMed Central

    2013-01-01

    Treatment of anorectal Buschke-Löwenstein tumor (BLT) with squamous cell carcinoma (SCC) transformation is not univocal given the rarity of the disease. BLT is characterized by its large size and tendency to infiltrate into underlying tissues. Malignant transformation can occur and it is important to identify the presence of neoplastic foci to decide the proper treatment. Our aim was to assess the effectiveness of neo-adjuvant chemo-radiation therapy (CRT) and local excision in order to avoid abdomino-perineal resection (APR). Three cases of anorectal BLT with SCC transformation are presented. All patients were HIV positive and treated with antiretroviral drugs. They underwent preoperative endoanal ultrasound, biopsies, total body tomography and anal brushing. Treatment consisted of neo-adjuvant chemo-radiation therapy (45 Gy to the pelvis plus a boost with 14.40 Gy to the primary tumor for a total of 59.40 Gy, and mitomycin-C in bolus on the first day, plus 5-fluorouracil by continuous infusion in the first and in the sixth week) and subsequent local surgical excision. During the follow-up, patients were subjected to the same preoperative diagnostic investigations and high resolution anoscopy. All patients showed a complete regression of the lesion after CRT and were treated by local surgical excision, thus avoiding permanent colostomy. In conclusion neo-adjuvant chemo-radiation therapy with local surgical excision could be considered an effective therapy in the treatment of anorectal BLT with SCC transformation to avoid APR.

    Aim: To evaluate the effect of non-surgical periodontal therapy on plasma lipid levels in hyperlipidemic patients with chronic periodontitis. Materials and Methods: After considering the inclusion and exclusion criteria, 30 hyperlipidemic patients with chronic periodontitis in the age group of 30–70 years, undergoing treatment in Ahmed Gasim Cardiac and Renal transplant Centre in north Sudan were recruited for the study. Patients were randomly assigned to the study and control groups. The study group received non-surgical periodontal therapy – oral hygiene instructions, scaling and root planing. The control group participants received only oral hygiene instructions. Lipid profile [total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG)], C-reactive protein (CRP), and periodontal parameters [Plaque index (PI), Gingival index (GI), probing pocket depth (PD), and attachment loss (ATL)] were measured and compared at baseline and after 3 months of the respective intervention. Between-groups analysis was done using independent “t” test and within-group analysis was done using dependent “t” test. Results: At baseline, groups were comparable based on lipid profile and periodontal parameters. After 3 months, the control group showed significant decrease in the PI and GI scores while there was no significant change in the other parameters. However, the study group showed significant decrease in the LDL and CRP levels along with a significant decrease in PD, ATL, PI, and GI scores, compared to the baseline values. Conclusion: Local non-surgical periodontal therapy resulted in improved periodontal health, with significant decrease in the LDL and CRP levels in hyperlipidemic patients with chronic periodontitis. Hence, local non-surgical periodontal therapy may be considered as an adjunct in the control of hyperlipidemia, along with standard care. PMID:25984468

    Background Cement dust contains heavy metals like nickel, cobalt, lead and chromium, pollutants hazardous to the biotic environment, with adverse impact for vegetation, human and animal health and ecosystems. Objective To investigate if long term exposure to cement dust can affect the periodontal health and affect the outcome of non-surgical periodontal therapy. Methods A total of sixty subjects were included in this study. Forty patients with chronic periodontitis were grouped into; Group I comprised of 20 patients with chronic periodontitis working in the Portland Cement Company and Group II comprised of 20 patients with chronic periodontitis who does not work in cement factories nor live near any of them. Twenty healthy subjects were included in this study as healthy control group (Group III). Clinical parameters including gingival index (GI), plaque index (PI), pocket depth (PD) and clinical attachment loss (CLA) were scored for all patients before and after periodontal therapy. All patients received non-surgical periodontal therapy together with strict oral hygiene program for one month. Gingival crevicular fluid (GCF) samples were collected from both groups at baseline and one month after periodontal therapy. Real time PCR (RT-PCR) was used to analyze the GCF samples for detection and assessment of the levels of IL-1β and TNFα. Results The two studied groups responded well to non-surgical periodontal treatment and there was no significant difference between GI and GII (P>0.05). The levels of TNFα was higher in GI than in GII before and after periodontal therapy (P<0.05). The levels of IL-1β did not show any significant difference between the two groups at base line (P>0.05), but represented with a highly significant difference between G1 and GII after periodontal therapy (P<0.001). A significant positive correlation was found between the levels of both IL-1β and TNFα and all the clinical parameters in GI before and after periodontal therapy and in GII

  18. The BEST-CLI trial: a multidisciplinary effort to assess whether surgical or endovascular therapy is better for patients with critical limb ischemia.

    Critical limb ischemia (CLI) is the most severe form of peripheral arterial disease and is associated with a risk of limb loss. This vascular condition is currently treated with limb revascularization by surgery or endovascular intervention performed by a variety of specialists. Because both open vascular bypass and the less invasive endovascular therapy can be performed in selected patients with CLI, there exists significant disagreement as to which therapy should be performed first and which is more successful. The paucity of comparative effectiveness data to guide treatment of CLI has prompted a multidisciplinary effort to organize the Best Endovascular Versus Best Surgical Therapy in Patients With CLI (BEST-CLI) trial. The BEST-CLI trial is a pragmatic, multicenter, open-label, randomized trial that compares best endovascular therapy with best open surgical treatment in patients eligible for both treatments. BEST-CLI aims to provide urgently needed clinical guidance for CLI management by using a pragmatic design comparing the effectiveness of established techniques while allowing for the introduction of newer therapies as they become available; a novel primary endpoint that includes limb amputation rates, repeat intervention, and mortality; a multidisciplinary structure that fosters cooperation among interventional cardiologists, interventional radiologists, vascular surgeons, and vascular medicine specialists; and novel techniques to evaluate the cost-effectiveness and quality-of-life outcomes of the two treatment strategies being tested.

    ABSTRACT OBJECTIVE: The objective of this retrospective study was to evaluate the efficacy of the authors’ combination therapy protocol for keloid treatment. DESIGN: Retrospective. SETTING: Plastic surgery office-based outpatient setting in New York City. PATIENTS: Forty patients with 44 keloid scars requiring surgical excision. INTERVENTIONS: Keloid scars were treated using surgical excision, platelet-rich plasma, and postoperative in-office superficial photon X-ray radiation therapy. Intralesional triamcinolone injections were administered once to 4 patients with poor results on scar scale assessment. Patient follow-up visits ranged from 3 to 11 months to assess for evidence of recurrence and adverse effects. MAIN OUTCOME MEASURE(S): For the purpose of this study, recurrence was defined as any sign of extraordinary erythema, induration, and hypertrophy beyond the site of excision. MAIN RESULTS: In the 16 keloids treated with 2 fractions, there was no evidence of recurrence. One of 25 keloids treated with 3 fractions demonstrated evidence of recurrence. One of 3 keloids treated with a single fraction displayed signs of recurrence. Postirradiation hyperpigmentation was noted in all patients. CONCLUSIONS: Surgical excision combined with platelet-rich plasma and postoperative in-office superficial radiation therapy achieved a 95.5% nonrecurrence rate at 1- to 3-month follow-up. This protocol appears to be a safe and viable option in the management of keloids and merits further randomized controlled study of its comparative efficacy. PMID:27300360

    Objective. Pain is multi-dimensional and may be better addressed through a holistic, biopsychosocial approach. Massage therapy is commonly practiced among patients seeking pain management; however, its efficacy is unclear. This systematic review and meta-analysis is the first to rigorously assess the quality of the evidence for massage therapy’s efficacy in treating pain, function-related, and health-related quality of life outcomes in surgical pain populations. Methods. Key databases were searched from inception through February 2014. Eligible randomized controlled trials were assessed for methodological quality using SIGN 50 Checklist. Meta-analysis was applied at the outcome level. A professionally diverse steering committee interpreted the results to develop recommendations. Results. Twelve high quality and four low quality studies were included in the review. Results indicate massage therapy is effective for treating pain [standardized mean difference (SMD) = −0.79] and anxiety (SMD = −0.57) compared to active comparators. Conclusion. Based on the available evidence, weak recommendations are suggested for massage therapy, compared to active comparators for reducing pain intensity/severity and anxiety in patients undergoing surgical procedures. This review also discusses massage therapy safety, challenges within this research field, how to address identified research gaps, and next steps for future research. PMID:27165970

    2010-09-01

    This review examined aggressive behavior in Borderline Personality Disorder (BPD) and its management in adults. Aggression against self or against others is a core component of BPD. Impulsiveness is a clinical hallmark (as well as a DSM-IV-TR diagnostic criterion) of BPD, and aggressive acts by BPD patients are largely of the impulsive type. BPD has high comorbidity rates with substance use disorders, Bipolar Disorder, and Antisocial Personality Disorder; these conditions further elevate the risk for violence. Treatment of BDP includes psychodynamic, cognitive behavioral, schema therapy, dialectic behavioral, group and pharmacological interventions. Recent studies indicate that many medications, particularly atypical antipsychotics and anticonvulsants, may reduce impulsivity, affective lability as well as irritability and aggressive behavior. But there is still a lack of large, double blind, placebo controlled studies in this area. PMID:20390357

    Objective The objective of this study is to discuss the management of advanced glomus jugulare tumors (GJTs) presenting with intradural disease and concurrent brainstem compression. Study Design This is a retrospective case series. Results Over the last decade, four patients presented to our institution with large (Fisch D2; Glasscock-Jackson 4) primary or recurrent GJTs resulting in brainstem compression of varying severities. All patients underwent surgical resection through a transtemporal, transcervical approach resulting in adequate brainstem decompression; the average operative time was 12.75 hours and the estimated blood loss was 2.7 L. All four patients received postoperative adjuvant radiotherapy in the form of intensity-modulated radiation therapy or stereotactic radiosurgery. Combined modality treatment permitted tumor control in all patients (range of follow-up 5 to 9 years). Conclusion A small subset of GJTs may present with intracranial transdural extension with aggressive brainstem compression mandating surgical intervention. Surgical resection is extremely challenging; the surgical team must be prepared for extensive operating time and the patient for prolonged aggressive rehabilitation. Newly diagnosed and recurrent large GJTs involving the brainstem may be controlled with a combination of aggressive surgical resection and postoperative radiation. PMID:23730549

    The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97

    Giant cell lesions (GCLs), previously referred to as giant cell granulomas, are benign tumors of the jaws of unknown etiology. Surgical management of aggressive GCLs is challenging, as these lesions demonstrate a tendency to recur following surgical removal. In addition, surgical treatment can be associated with significant morbidity. In an attempt to reduce both the extent of morbidity and the recurrence rate following surgery, a number of pharmacologic therapies have been advocated on the basis of assumptions about the predominant cell types and receptors, for the management of these lesions. This report describes the use of denosumab, an agent originally used for its anti-resorptive effects, in the management of an aggressive GCL of the mandible in an older patient, who was unsuitable for extensive surgery and in whom treatment with intralesional triamcinolone had proved unsuccessful. Denosumab may be a viable alternative or adjunct to surgery in the management of GCLs of the jaws. PMID:26340897

    Introduction. International guidelines recommend interruption of anti-TNF medications in the perioperative period, but there are no randomized trials to support such recommendation. Objectives. To study literature evidence assessing the risk of surgical site infections in orthopedic surgery patients with RA using anti-TNF drugs, compared to untreated patients or those using conventional DMARD. Methods. Systematic review of cohort studies is concerning surgical site infections in orthopedic procedures in patients with RA. Results. Three studies were selected. Only one was considered of high-quality, albeit with low statistical power. The review resulted in inconclusive data, since the best quality study showed no significant differences between groups, while others showed increased risk of infections in patients using anti-TNF medications. Conclusion. It is unclear whether patients with RA using anti-TNF medications are at increased risk of surgical site infections. Randomized controlled trials or new high quality observational studies are needed to clarify the issue. PMID:22500176

    Purpose: Brain metastases of melanoma, renal carcinoma, and sarcoma have traditionally responded poorly to conventional treatments, including surgery and whole-brain radiotherapy (WBRT). Several studies have suggested a beneficial effect of stereotactic radiosurgery (SRS). We evaluated our institutional experience with systematic SRS in patients harboring these 'radioresistant' metastases. Methods and Materials: A total of 68 patients with brain metastases from melanoma, renal carcinoma, and sarcoma underwent SRS with or without WBRT or surgical resection. All patients had Karnofsky performance scores >70, and SRS was performed before the initiation of systemic therapy. The survival time was calculated from the diagnosis of brain metastases using the Kaplan-Meier product-limit method. Statistical significance was calculated using the log-rank test. Factors influencing survival, including surgical resection, WBRT, gender, number of SRS sessions, and histologic type, were evaluated retrospectively using Cox univariate models. Results: The overall median survival was 427 days (14.2 months), which appears superior to the results obtained with conventional WBRT. The addition of neither surgery nor WBRT to SRS provided a statistically significant increase in survival. Conclusion: Our results suggest that patients undergoing SRS for up to five cerebral metastases from 'radioresistant' tumors (melanoma, renal cell carcinoma, and sarcoma) have survival rates comparable to those in other series of more selected patients. The addition of surgical resection or WBRT did not result in improved survival in our series.

    Objective: To present the clinical management of inguinal disruption in a professional hockey player and highlight the importance of a multidisciplinary approach to diagnosis and management. Clinical Features: A professional hockey player with recurrent groin pain presented to the clinic after an acute exacerbation of pain while playing hockey. Intervention: The patient received a clinical diagnosis of inguinal disruption. Imaging revealed a tear in the rectus abdominis. Management included two platelet-rich plasma (PRP) injections to the injured tissue, and subsequent manual therapy and exercise. The patient returned to his prior level of performance in 3.5 weeks. Discussion: This case demonstrated the importance of a multidisciplinary team and the need for advanced imaging in athletes with groin pain. Summary: Research quality concerning the non-surgical management of inguinal disruption remains low. This case adds evidence that PRP, with the addition of manual therapy and exercise may serve as a relatively quick and effective non-surgical management strategy. PMID:26816415

    Mucormycosis is a rare, highly lethal opportunistic fungal disease affecting immune compromised and diabetic patients. Mucormycosis is considered as the 3rd most common invasive mycosis after candidiasis and aspergillosis in debilitating patients. It is caused by the filamentous fungi of the class zygomycetes. The infection usually begins in the nose due to inhalation of fungal spores. This fatal fungal disease needs a prompt and early definitive diagnosis, aggressive surgical therapy and high dose anti-fungal therapy. Here, we present a case report of Mucormycosis in a 64 year elderly diabetic male patient who was previously operated for myiasis and also the extensive review of the literature of the mucormycosis.

    The extent of the surgical resection necessary for breast cancer patients treated by primary radiation therapy is unknown. A simple gross excision of the tumor provides the best cosmetic result, but a wide local resection may be important to prevent local recurrence in some patients. In order to identify patients who are not adequately treated by gross excision of the tumor and radiation therapy, we performed a retrospective clinical-pathologic review of 221 treated women with infiltrating duct carcinoma. There were 53 cases in which the excision specimen showed a constellation of three pathologic features: prominent intraductal carcinoma in the tumor, intraductal carcinoma in the grossly-normal adjacent tissue, and poorly-differentiated nuclei. These cases had a 37% risk of a local recurrence at 6 years compared to eight per cent for all other cases (p less than 0.0001). In cases with all three features, the use of a supplemental dose of radiation to the primary site did not significantly reduce the risk of a local recurrence. Local recurrence at 6 years was 34% in cases with all three features, who received supplemental local radiation, compared to 49% in cases not receiving a supplemental dose (p = 0.28). Survival was also worse for patients with all three features compared to other cases (69% vs. 90% at 6 years, p = 0.002). These results indicate that patients with all three pathologic features have a high risk of local recurrence following gross excision of the tumor and radiation therapy. If primary radiation therapy is selected for these patients, they should first undergo a re-excision of the tumor site in order to be certain that areas of extensive intraductal carcinoma have been adequately resected. Patients whose tumors do not show all three features are adequately treated by gross excision of the tumor prior to radiation therapy. PMID:2982337

    Importance Chronic periodontitis, a destructive inflammatory disorder of the supporting structures of the teeth, is prevalent in patients with diabetes. Limited evidence suggests that periodontal therapy may improve glycemic control. Objective To determine if non-surgical periodontal treatment reduces hemoglobin A1c (HbA1c) in persons with type 2 diabetes (DM) and moderate to advanced chronic periodontitis. Design, Setting and Participants The Diabetes and Periodontal Therapy Trial (DPTT) is a 6-month, single-masked, randomized, multi-center clinical trial. Participants had DM, were taking stable doses of medications, had HbA1c ≥7% and <9%, and untreated periodontitis. Five hundred fourteen participants were enrolled between November 2009 and March 2012 from diabetes and dental clinics and communities affiliated with five academic medical centers. Intervention The treatment group (n=257) received scaling and root planing plus chlorhexidine oral rinse at baseline, and supportive periodontal therapy at three and six months. The control group (n=257) received no treatment for six months. Main Outcome Measure Difference in HbA1c change from baseline between groups at six months. Secondary outcomes included changes in probing pocket depths, clinical attachment loss, bleeding on probing, gingival index, fasting glucose, and the Homeostasis Model Assessment (HOMA2). Results Enrollment was stopped early due to futility. At 6 months, the periodontal therapy group increased HbA1c 0.17% (1.0) (mean (SD)) compared to 0.11% (1.0) in the control group, with no significant difference between groups based on a linear regression model adjusting for clinical site (mean difference = -0.05%; 95% Confidence Interval (CI): -0.23%, 0.12%; p=0.55). Probing depth, clinical attachment loss, bleeding on probing and gingival index measures improved in the treatment group compared to the control group at six months with adjusted between-group differences of 0.33mm (95% CI: 0.26, 0.39), 0

    Aggressive angiomyxoma is a rare mesenchymal tumor involving the pelvic-perineal region. It occurs during the third and fourth decade of life and is predominantly seen in females. It presents clinically as a soft tissue mass in variable locations such as vulva, perianal region, buttock, or pelvis. Assessment of extent of the tumor by radiological evaluation is crucial for surgical planning; however, biopsy is essential to establish diagnosis. We present the radiological and pathological features seen in a 43-year-old female diagnosed with abdominal angiomyxoma with an unusual extension to the perineum. PMID:24987570

    Glioblastoma (GBM) is the most common and fatal type of primary brain tumor. Gliosarcoma (GSM) is a rarer and more aggressive variant of GBM that has recently been considered a potentially different disease. Current clinical treatment for both GBM and GSM includes maximal surgical resection followed by post-operative radiotherapy and concomitant and adjuvant chemotherapy. Despite recent advances in treating other solid tumors, treatment for GBM and GSM still remains palliative, with a very poor prognosis and a median survival rate of 12–15 months. Treatment failure is a result of a number of causes, including resistance to radiotherapy and chemotherapy. Recent research has applied the cancer stem cells theory of carcinogenesis to these tumors, suggesting the existence of a small subpopulation of glioma stem-like cells (GSCs) within these tumors. GSCs are thought to contribute to tumor progression, treatment resistance, and tumor recapitulation post-treatment and have become the focus of novel therapy strategies. Their isolation and investigation suggest that GSCs share critical signaling pathways with normal embryonic and somatic stem cells, but with distinct alterations. Research must focus on identifying these variations as they may present novel therapeutic targets. Targeting pluripotency transcription factors, SOX2, OCT4, and Nanog homeobox, demonstrates promising therapeutic potential that if applied in isolation or together with current treatments may improve overall survival, reduce tumor relapse, and achieve a cure for these patients.

    Surgery is gold-standard for correction of Peyronie's curvature. Grafting is preferred in advanced deviations. We present our novel surgical technique and early results of grafting with collagen fleece. Patients with stable Peyronie's disease (PD) were included. Grafting was performed by a ready-to-use collagen fleece coated with tissue sealant (TachoSil, Nycomed, Konstanz, Germany), following partial plaque excision/incision. Results of correction were documented by artificial erection. In all, n=70 consecutive patients underwent surgery. Mean patient age was 56.4 years (range: 33-72); 88.6% of patients had dorsal deviation, 11.4% lateral or ventral deviation. Grafting after partial plaque excision was performed in 61 patients (87.1%), after plaque incision in 2 (2.9%) patients. In the former patients, mean operative time was 94.2 min (range: 65-165). Totally straightness was achieved in 83.6%. Three patients required surgical drainage because of subcutaneous haematoma formation. After mean early follow-up of 5.2 days (range: 2-15), glans sensation was normal in 56 patients (91.8%). Seven patients (10.0%) underwent Nesbit procedure alone. Grafting by collagen fleece in PD is feasible and promising. Major advantages are decreased operative times and easy application. Moreover, an additional haemostatic effect is provided. However, long-term clinical outcomes are necessary to confirm these encouraging findings. PMID:23446807

    Coronary artery disease (CAD) is the leading cause of death in patients with diabetes mellitus (DM). Patients with DM and CAD undergoing revascularization with either a surgical or a percutaneous approach are at higher risk of adverse outcomes and mortality compared with non-DM patients. It is within this background that the optimal choice of revascularization is of critical importance in this high-risk population. The large FREEDOM trial randomized 1900 patients with DM and multivessel CAD to either revascularization with coronary artery by-pass graft (CABG) surgery or percutaneous coronary intervention (PCI). Compared with PCI, CABG significantly reduced the rates of death and myocardial infarction but was associated with a higher risk of stroke. In a real-world setting the decision-making process for the optimal revascularization strategy in these patients is challenging as many clinical factors may influence the decision to either pursue a surgical or a percutaneous revascularization. However, the current consensus is that CABG should be the preferred revascularization strategy in diabetic patients with extensive multivessel CAD. PMID:26255239

    The role of goal-directed therapy in high-risk cardiac surgical patients has not been determined. This study sought to observe the effect of a postoperative standardised haemodynamic protocol (SHP) on the administration of fluid and vasoactive drugs after high-risk cardiac surgery. This was an interventional pilot study. In 2010 to 2011, the SHP was introduced to the ICU at Wellington Regional Hospital, Wellington, New Zealand, for the perioperative management of patients undergoing high-risk cardiac surgery. A pulmonary artery catheter was inserted in the patients in the study group and fluids and supportive medications were provided in the ICU according to a protocol that targeted a cardiac index ≥ 2 l/min/m², mixed venous oxygen saturation ≥ 60% and a mean arterial pressure of 65 to 75 mmHg. Data from 40 consecutive high-risk cardiac surgical patients assigned to this protocol were compared with a matched cohort of 40 consecutive high-risk cardiac surgical patients receiving 'usual care' in 2009. Baseline characteristics were similar in the two groups. There was no significant difference in the duration of noradrenaline infusion in the SHP cohort compared to historical controls (median [IQR] 18.5 hours [31.63] versus 18 hours [18.3]; P=0.35), despite patients receiving more fluid in their first 12 hours in the ICU (mean 4687 ml [SD ± 2284 ml] versus 1889 ml [SD ± 1344 ml]; P <0.001). The SHP cohort had a higher rate of reintubation (4 in 37 [10.8%] versus 0 in 40 [0%]; P=0.049). The SHP delivered significantly more fluid, but did not reduce the duration of noradrenaline infusion, compared to usual care. PMID:26310413

    Introduction: The aim of this study was to evaluate the primary and secondary therapeutic successes of different therapy schemes for the treatment of synechia of the labia in pre-pubertal girls. Materials and Methods: The treatment courses of 47 pre-pubertal girls who were treated between February 2007 and February 2013 in the special outpatient clinic for paediatric gynaecology of a department for gynaecology at a German university hospital and for whom information on the course of the disease was available for at least the six months following end of the treatment. 23 of these children were treated with a topical estriol therapy (treatment group A). For 24 of the girls a manual separation of the adhering labia minora was undertaken (treatment group B). Statistical evaluation was performed using the χ2 test, Fischerʼs exact test and the Mann-Whitney U test. Results: For 18 of the 23 (80 %) girls in treatment group A topical estriol therapy alone led to a resolution of the synechia. Five of these 23 children (20 %) required a secondary manual separation. All girls for whom treatment was not successful were under 5 years of age. For all 24 girls (100 %) of treatment group B the primary manual separation was performed with success. The recurrence rates after ≥ 6 months in cases with identical after-care did not differ between the two treatment groups (treatment group A: 34 %, treatment group B: 33 %, χ2 test: p = 0.853). 16 of the 17 recurrences occurred ≥ 3 months after the end of the therapy. Conclusion: Our results show that for children < 5 years of age a 4-week topical therapy with estriol is a promising therapy option for synechia of the labia that is less of a burden for the family situation. Especially for girls ≥ 5 years of age, primary therapy fails in up to 20 % of the cases. Primary manual separation represents a more effective therapeutic option. Irrespective of the treatment applied, a recurrence after ≥ 3 must be

    Introduction: Aggressive fibromatosis (AF) is a heterogeneous group of mesenchymal tumors that have locally infiltrative growth and a tendency to relapse. The clinical picture is often conditioned by the obstruction of the ureter or small intestine. Diagnosis is based on clinical, radiological and histological parameters. A case report: We report a case of male patient, aged 35 years, with the retroperitoneal fibromatosis. He reported to the physician because of frequent urination with the feeling of pressure and pain. Computed tomography revealed the tumor mass on the front wall of the bladder with diameter of 70mm with signs of infiltration of the musculature of the anterior abdominal wall. Endoscopic transurethral biopsy showed proliferative lesion binders by type of fibromatosis. The tumor was surgically removed in a classical way. The patient feels well and has no recurrence thirty-six months after the operative procedure. Conclusion: The complete tumor resection is the therapeutic choice for the primary tumor as well as for a relapse. PMID:27147794

    We describe the case of an 80-year-old Hispanic male with an acute subarachnoid hemorrhage (SAH) due to an inflammatory middle cerebral artery (MCA) aneurysm rupture. Two years prior to this episode, the patient had undergone a resection of a left intracranial neurocysticercosis lesion. A current CT, CTA and MRI showed significant SAH, a left MCA aneurysm and a cystic lesion compatible with neurocysticercosis. Intraoperatively, this aneurysm was found to be adjacent to a neurocysticercosis cyst, a diagnosis confirmed by surgical pathology. Only a few cases of subarachnoid hemorrhage due to an inflammatory brain aneurysm have been reported. Due to the associated higher incidence of intraoperative rupture and difficulty clipping, our paper highlights the importance of considering an inflammatory origin in patients with a history of neurocysticercosis and subarachnoid hemorrhage. This is the oldest patient on record reported for this diagnosis and surgery. PMID:24028987

    Laser use for biopsy of suspicious lesions may simulate cytological atypia at the margin of the incisions, challenging pathological diagnosis. Erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser has shown promising results in experimental models by inducing fewer artifacts. The aims of this study were to examine the thermal wounds induced by Er,Cr:YSGG laser in a short series of oral leukoplakias in terms of cytological and epithelial architectural changes and also to assess the width of the thermal damage lateral to the incision. Four oral leukoplakia patients entered the study and underwent complete surgical excision of their lesions by using Er,Cr:YSGG laser. Patients were weekly controlled until complete healing was accomplished. The patients were included on the existing follow-up program for these lesions thereafter. Study samples were routinely processed by the same technician and double-blindedly studied by two pathologists until a consensus was reached for each case. The pathological analysis of the samples revealed no autolysis and no fixation- or handling-related artifacts. However, cellular and nuclear polymorphism could be observed in two samples. Loss of intercellular adherence was the most frequent thermal artifact in this series; all pseudodysplastic artifacts recognized in the study were of low intensity and located at the basal and suprabasal layers of the leukoplakias' epithelium. The width of the thermal damage at the edge of the incision scored an average of 26.60 ± 25.3 μm. It is concluded that irradiation with Er,Cr:YSGG laser induces a minimal amount of thermal artifacts at the surgical margins of oral leukoplakias and avoids diagnostic interferences with real dysplastic borders.

    Differentiated thyroid cancer (DTC) is the most common endocrine malignancy and the fifth most common cancer in women. DTC therapy requires a multimodal approach, including surgery, which is beyond the scope of this paper. However, for over 50 years, the post-operative management of the DTC post-thyroidectomy patient has included radioactive iodine (RAI) ablation and/or therapy. Before 2000, a typical RAI post-operative dose recommendation was 100 mCi for remnant ablation, 150 mCi for locoregional nodal disease, and 175-200 mCi for distant metastases. Recent recommendations have been made to decrease the dose in order to limit the perceived adverse effects of RAI including salivary gland dysfunction and inducing secondary primary malignancies. A significant controversy has thus arisen regarding the use of RAI, particularly in the management of the low-risk DTC patient. This debate includes the definition of the low-risk patient, RAI dose selection, and whether or not RAI is needed in all patients. To allow the reader to form an opinion regarding post-operative RAI therapy in DTC, a literature review of the risks and benefits is presented. PMID:25277792

    Objectives: Traumatic wounds and surgery inherently have their complications. Localized infections, wound dehiscence, and excessive wound leakage can be devastating to the patient with a prolonged recovery, but it is also costly to the hospital with an increased length of stay, extra workload, and dressing changes. The single use PICO (Smith and Nephew Healthcare, Hull, United Kingdom) negative pressure wound therapy (NPWT) dressing has revolutionized our management of various acute, chronic, and high output wounds. It requires fewer dressing changes than conventional practice, is used in the outpatient setting, and is a necessary adjuvant therapy to hasten wound healing. Aims: To observe the efficacy of the PICO vacuum-assisted healing within a cost improvement programme. Settings: Plastic surgery department, Royal London Hospital. Materials and Methods: Twenty-one patients with a diversity of postoperative or posttraumatic wounds were considered suitable for PICO application and treated totally on an outpatient basis once the PICO dressing was applied. All wounds were then subjected to continued PICO dressings until healed. Results: All patients tolerated the PICO well with no dressing failure or failure to comply. The number of dressings per patient ranged from 1 to 7. The cost per patient of treatment ranged from £120 to £1578. Estimated cost of all PICO dressing for 21 patients including plastic surgery dressing clinic appointments = £13,345. Median length of treatment to healing (days) = 16; standard deviation = 9.5. Eight patients would have had an inpatient bed stay with conventional therapy, total 24 bed days saved at Bartshealth @£325 per day. Conclusions: The outpatient application of a disposable NPWT can benefit a wide range of clinical wounds that optimizes patient care, promotes rapid wound healing, and importantly helps manage costs.

    An enhanced musculoskeletal biomechanical model of the wrist joint is presented in this article. The computational model is based on the multi-body simulation software AnyBody. Multi body dynamic musculoskeletal models capable of predicting muscle forces and joint contact pressures simultaneously would be valuable for studying clinical issues related to wrist joint degeneration and restoration. In this study, the simulation model of the wrist joint was used for investigating deeper the biomechanical function of the wrist joint. In representative physiological scenarios, the joint behavior and muscle forces were computed. Furthermore, the load transmission of the proximal wrist joint was investigated. The model was able to calculate the parameters of interest that are not easily obtainable experimentally, such as muscle forces and proximal wrist joint forces. In the case of muscle force investigation, the computational model was able to accurately predict the computational outcome for flexion and extension motion. In the case of force distribution of the proximal wrist joint, the model was able to predict accurately the computational outcome for an axial load of 140 N. The presented model and approach of using a multi-body simulation model are anticipated to have value as a predictive clinical tool including effect of injuries or anatomical variations and initial outcome of surgical procedures for patient-specific planning and custom implant design. Therefore, patient-specific multi-body simulation models are potentially valuable tools for surgeons in pre- and intraoperative planning of implant placement and orientation. PMID:26994118

    Evidence suggests a correlation between the gut microbiota composition and weight loss caused by caloric restriction. Laparoscopic sleeve gastrectomy (LSG), a surgical intervention for obesity, is classified as predominantly restrictive procedure. In this study we investigated functional weight loss mechanisms with regard to gut microbial changes and energy harvest induced by LSG and a very low calorie diet in ten obese subjects (n = 5 per group) demonstrating identical weight loss during a follow-up period of six months. For gut microbiome analysis next generation sequencing was performed and faeces were analyzed for targeted metabolomics. The energy-reabsorbing potential of the gut microbiota decreased following LSG, indicated by the Bacteroidetes/Firmicutes ratio, but increased during diet. Changes in butyrate-producing bacterial species were responsible for the Firmicutes changes in both groups. No alteration of faecal butyrate was observed, but the microbial capacity for butyrate fermentation decreased following LSG and increased following dietetic intervention. LSG resulted in enhanced faecal excretion of nonesterified fatty acids and bile acids. LSG, but not dietetic restriction, improved the obesity-associated gut microbiota composition towards a lean microbiome phenotype. Moreover, LSG increased malabsorption due to loss in energy-rich faecal substrates and impairment of bile acid circulation. This trial is registered with ClinicalTrials.gov NCT01344525.

    Systemic antibiotic treatment has emerged as a powerful adjunct to conventional mechanical debridement for therapeutic management of the periodontal diseases. The conceptual basis for treating periodontal diseases as infections is particularly attractive in part because of substantial data indicating that these diseases may be associated with specific putative pathogens. Further, discrete groups of patients respond well to systemic antibiotics and exhibit improvement of clinical parameters, including attachment level and inflammation. This bacterial-host interaction, which is ever-so-present in periodontitis, directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report presents a case of a female patient with recurrence of the chronic generalized periodontitis with gingival enlargement, which is treated thrice by referral dentist. A through clinical examination was carried out pre-operatively and treatment was planned with systemic minocycline in conjunction with the conventional non-surgical approach. There was a significant reduction of pocket depth, gain in attachment with dramatic improvement clinically. PMID:24872639

    The development of image guided robotic and mechatronic platforms for medical applications requires a phantom model for initial testing. Finding an appropriate phantom becomes challenging when the targeted patient population is pediatrics, particularly infants, neonates or fetuses. Our group is currently developing a pediatricsized surgical robot that operates under fused MRI and laparoscopic video guidance. To support this work, we describe a method for designing and manufacturing silicone rubber organ phantoms for the purpose of testing the robotics and the image fusion system. A surface model of the organ is obtained and converted into a mold that is then rapid-prototyped using a 3D printer. The mold is filled with a solution containing a particular ratio of silicone rubber to slacker additive to achieve a specific set of tactile and imaging characteristics in the phantom. The expected MRI relaxation times of different ratios of silicone rubber to slacker additive are experimentally quantified so that the imaging properties of the phantom can be matched to those of the organ that it represents. Samples of silicone rubber and slacker additive mixed in ratios ranging from 1:0 to 1:1.5 were prepared and scanned using inversion recovery and spin echo sequences with varying TI and TE, respectively, in order to fit curves to calculate the expected T1 and T2 relaxation times of each ratio. A set of infantsized abdominal organs was prepared, which were successfully sutured by the robot and imaged using different modalities.

    Aggressive natural killer cell leukemia (ANKL) is a rare and often lethal lymphoproliferative disorder. Patients may present with constitutional symptoms, jaundice, skin infiltration, lymphadenopathy, and hepatosplenomegaly. ANKL can progress quickly to multiorgan failure and survival is usually measured in weeks. Although a rapid and accurate diagnosis is critical, unfortunately there is no hallmark diagnostic marker of ANKL. We report a case of a 48-year-old male who was able to obtain a complete remission following cisplatin-based chemotherapy. We describe the details of the chemotherapy regimens used and a literature review of the treatment of ANKL. PMID:25694835

    2013-01-01

    Background: Adhesion formation is a widely acknowledged risk following abdominal or pelvic surgery. Adhesions in the abdomen or pelvis can cause or contribute to partial or total small bowel obstruction (SBO). These adhesions deter or prevent the passage of nutrients through the digestive tract, and may bind the bowel to the peritoneum, or other organs. Small bowel obstructions can quickly become life-threatening, requiring immediate surgery to resect the bowel, or lyse any adhesions the surgeon can safely access. Bowel repair is an invasive surgery, with risks including bowel rupture, infection, and peritonitis. An additional risk includes the formation of new adhesions during the healing process, creating the potential for subsequent adhesiolysis or SBO surgeries. Objective: Report the use of manual soft tissue physical therapy for the reversal of adhesion-related partial SBOs, and create an initial inquiry into the possibility of nonsurgical lysis of adhesions. Case Reports: Two patients presenting with SBO symptoms due to abdominal adhesions secondary to abdominal and pelvic surgery were treated with manual soft tissue physical therapy focused on decreasing adhesions. Conclusions: Successful treatment with resolution of symptom presentation of partial SBO and sustained results were observed in both patients treated. PMID:26237678

    Drawing from developmental theories of relational aggression, this article reports on a study designed to identify if spouses use relationally aggressive tactics when dealing with conflict in their marriage and the association of these behaviors with marital outcomes. Using a sample of 336 married couples (672 spouses), results revealed that the majority of couples reported that relationally aggressive behaviors, such as social sabotage and love withdrawal, were a part of their marital dynamics, at least to some degree. Gender comparisons of partner reports of their spouse's behavior revealed that wives were significantly more likely to be relationally aggressive than husbands. Structural equation modeling demonstrated that relational aggression is associated with lower levels of marital quality and greater marital instability for both husbands and wives. Implications are drawn for the use of relational aggression theory in the future study of couple conflict and marital aggression. PMID:20698028

    Background BRCA-associated protein 1, an enzyme encoded by the BAP1 gene, is commonly mutated in uveal melanoma, mesothelioma, and renal cancers. Tumors with BAP1 mutation follow an aggressive course. BAP1 mutations have also been observed in cholangiocarcinoma (CCA). The clinical phenotype of BAP1 mutant CCA may yield useful prognostic and therapeutic information but has not been defined. Methods The records of CCA patients who underwent next-generation sequencing (NGS) were reviewed, and data on clinical, histopathological, genetic, and radiological features; response to therapy; time to progression; and survival were analyzed. Results Twenty-two cases of BAP1-mutation associated CCA were diagnosed from January 1, 2009, to February 1, 2015, at our center. Twenty patients had intrahepatic CCA and two had extrahepatic CCA. Tumor sizes (largest dimension) ranged from 2 to 16 cm (mean, 8.5 cm). Twelve patients had tumors that were poorly differentiated. Majority of the patients had advanced disease at presentation and 13 had bone metastases. Thirteen patients (59%) experienced rapidly progressive disease following primary therapy (chemotherapy or surgical resection). The mean time to tumor progression was 3.8 months after the first line chemotherapy. Conclusions BAP1 mutation in CCA may be associated with aggressive disease and poor response to standard therapies. Therefore, BAP1-targeted therapies need to be investigated. PMID:27563445

    Seventy-eight patients under the age of 40 (low-risk patients) who had undergone surgical treatment for well-differentiated thyroid carcinoma were referred from 1979 to 1986 to our hospital for adjuvant therapy. A subgroup of 37 patients, 14 with apparent aggressive cancer, was studied. This study group consisted of 27 female and 10 male patients with mixed papillary and follicular cancer, who ranged in age from 11 to 40 years. Nodal disease occurred in 27 (73%) patients and invasiveness in 30 (81%) patients and involved multiple areas in 9 (24%) patients. Recurrence occurred in 14 (38%) patients and visceral metastases occurred in eight (22%) patients. All patients underwent appropriate surgery, but microscopic residual disease was seen in 15 patients and gross residual disease in seven patients, so that 31 patients underwent iodine-131 therapy, and 17 of these patients also underwent external radiation therapy. Three patients died of their disease, whereas 24 (65%) patients are free of disease and 9 (24%) patients are alive with disease. An additional 7 (19%) patients were initially seen in the fifth to seventh decade after decades of neglected thyroid disease, which culminated in residual cancer and death. Although low-risk categorization for thyroid cancer appears valid, its rigid application in support of conservative treatment may lead to inadequate primary treatment and underdiagnosis of cancer in thyroid nodule disease in the low-risk age population.

    Purpose/Objectives: The aim of this study was to evaluate the impact of definitive thoracic chemoradiation therapy following surgery or stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) on the outcomes of patients with non-small cell lung cancer (NSCLC) with synchronous solitary brain metastasis (SSBM). Methods and Materials: A total of 63 NSCLC patients with SSBM were retrospectively evaluated. Patients were staged using positron emission tomography-computed tomography in addition to conventional staging tools. Thoracic radiation therapy (TRT) with a total dose of 66 Gy in 2 Gy fractions was delivered along with 2 cycles of cisplatin-based chemotherapy following either surgery plus 30 Gy of WBRT (n=33) or SRS plus 30 Gy of WBRT (n=30) for BM. Results: Overall, the treatment was well tolerated. All patients received planned TRT, and 57 patients (90.5%) were also able to receive 2 cycles of chemotherapy. At a median follow-up of 25.3 months (7.1-52.1 months), the median months of overall, locoregional progression-free, neurological progression-free, and progression-free survival were 28.6, 17.7, 26.4, and 14.6, respectively. Both univariate and multivariate analyses revealed that patients with a T1-T2 thoracic disease burden (P=.001), a nodal stage of N0-N1 (P=.003), and no weight loss (P=.008) exhibited superior survival. Conclusions: In the present series, surgical and radiosurgical treatments directed toward SSBM in NSCLC patients were equally effective. The similarities between the present survival outcomes and those reported in other studies for locally advanced NSCLC patients indicate the potentially curative role of definitive chemoradiation therapy for highly selected patients with SSBM.

    To investigate the effect of metal implants in proton radiotherapy, dose distributions of different, clinically relevant treatment plans have been measured in an anthropomorphic phantom and compared to treatment planning predictions. The anthropomorphic phantom, which is sliced into four segments in the cranio-caudal direction, is composed of tissue equivalent materials and contains a titanium implant in a vertebral body in the cervical region. GafChromic® films were laid between the different segments to measure the 2D delivered dose. Three different four-field plans have then been applied: a Single-Field-Uniform-Dose (SFUD) plan, both with and without artifact correction implemented, and an Intensity-Modulated-Proton-Therapy (IMPT) plan with the artifacts corrected. For corrections, the artifacts were manually outlined and the Hounsfield Units manually set to an average value for soft tissue. Results show a surprisingly good agreement between prescribed and delivered dose distributions when artifacts have been corrected, with > 97% and 98% of points fulfilling the gamma criterion of 3%/3 mm for both SFUD and the IMPT plans, respectively. In contrast, without artifact corrections, up to 18% of measured points fail the gamma criterion of 3%/3 mm for the SFUD plan. These measurements indicate that correcting manually for the reconstruction artifacts resulting from metal implants substantially improves the accuracy of the calculated dose distribution.

  2. [Recognizing and assessing aggressive behaviour in dogs].

    Within the population the sensitivity to aggressive behaviour in dogs has increased. The authorities are confronted with a problem: if any incident occurs it is their task to decide whether the dogs involved constitute a threat to other people or whether the charge is only the result of a quarrel between neighbours. For this reason, an examination of the dogs with regard to their aggressive behaviour is necessary. Seen from the biological point of view, aggressive behaviour is one of four possibilities a dog can chose from to solve a conflict. The dog's intention in showing aggressive behaviour is to eliminate disturbances and to maintain a distance in space and time. Aggressive behaviour might also be necessary to acquire or defend resources essential to the dog's life. This is to secure its survival and its success in reproduction. One can see from this that aggressive behaviour is a very important and biologically necessary adjustment factor. However, when living together with man aggressive behaviour might become a problem. For the assessment and the therapy of the problem it is necessary to exa-mine the behaviour shown by the dog with regard to its cause. To be able to do this an exact anamnesis, a medical check, and an examination of the dog on the basis of its display in special situations are necessary. For this reason, exclusively veterinarians with a special further education in the field of behaviour should carry out the examination of dogs. PMID:16669189

    . Power calculations showed that more patients were needed to reach statistical significance for these parameters. The presence of a faecalith was most often associated with a gangrenous or perforated appendix. No significant differences were found between the CTT and faecal load of patients who had or did not have a faecalith. However, the right-sided faecal load was significantly higher than the left and distal load. Haemorrhoids are often a consequence of constipation and defaecatory disorders and were found in every second patient with functional bowel disorders. The present studies are the first Danish reports of a novel operation to cure this disease, stapled haemorrhoidopexy (n = 40 and 258 patients). The majority of patients had prolapsed haemorrhoids, and the durability of procedure was confirmed with a follow-up of up to 5 years, meaning a normal anus. The operation time was short, post-operative pain was low, and recovery was rapid. No incontinence was observed, and patient satisfaction was high and significantly correlated with the appearance of a normal anus without prolapse. The cumulative risk of re-operation was greatest in the first 2 years after the stapled haemorrhoidopexy. Patients with persisting haemorrhoidal prolapse had the procedure repeated with results as good as those obtained in the rest of the patients. It was shown in a statistical model that the preoperative severity of haemorrhoidal disease and the immediate postoperative result contributed significantly to predicting the outcome that is the durability of the operation. The most frequent post-operative complication was bleeding requiring surgical haemostasis. One serious complication occurred after an anastomotic leak from a highly placed anastomosis, resulting in retro rectal, retro- and intra-peritoneal, and mediastinal gas. The patient recovered after conservative treatment and without surgical intervention. The stapling technique now used has revolutionized the surgical treatment of

Our article provides an overview of the different types of surgical airways. This article provides a comprehensive review of the main types of surgical airways, relevant anatomy, necessary equipment, indications and contraindications, preparation and positioning, technique, complications, and tips for management. It is important to remember that the placement of a surgical airway is a lifesaving procedure and should be considered in any setting when one “cannot intubate, cannot ventilate”. PMID:24741501

    In Study 1, 198 men completed the Right Wing Authoritarianism, Sex Role Ideology, Hostility Towards Women, Acceptance of Interpersonal Violence, Adversarial Sexual Beliefs, and Rape Myth Acceptance scales, as well as measures of past sexually aggressive behavior and likelihood of future sexual aggression. As predicted, authoritarianism and sex role ideology were as closely related to self-reported past and potential future sexually aggressive behavior as were the specifically sexual and aggression-related predictors. Among 134 men in Study 2, authoritarianism and sex guilt positively correlated with each other and with self-reported past sexual aggression. In both studies, the relationship of authoritarianism and sexual aggression was larger in community than in university samples. PMID:8246111

    Background: Neoadjuvant chemotherapy for potentially resectable metastatic colorectal cancer (MCC) is becoming a more common treatment algorithm. The aim of the present study was to evaluate the efficacy of precision hepatic arterial Irinotecan therapy in unresectable MCC. Methods: An open-label, multi-centre, multi-national single arm study of MCC patients, who received hepatic arterial irinotecan. Primary endpoints were safety, tolerance and metastatic tumour resection. Results: Fifty-five patients with metastatic colorectal to the liver underwent a total of 90 hepatic arterial irinotecan treatments. The extent of liver involvement was <25% in 75% of the patients (n= 41), between 26 and 50% in 15% of the patients (n= 11) and >50% in 10% of the patients (n= 24). The median number of hepatic lesions was four (range 1–20), with a median total size of all target lesions of 9 cm (range 5.5–28 cm) with 50% of patients having bilobar tumour distribution. The median number of irinotecan treatments was two (range 1–5). The median treatment dose was 100 mg (range 100–200) with a median total hepatic treatment of 200 mg (range 200–650). The majority of treatments (86%) were performed as lobar infusion treatments, and 30% of patients were treated with concurrent simultaneous chemotherapy. Eleven (20%) patients demonstrated significant response and downstage of their disease or demonstrated stable disease without extra-hepatic disease progression allowing resection, ablation or resection and ablation. There were no post-operative deaths. Post-operative complications morbidity occurred in 18% of patients, with none of them hepatic related. Non-tumorous liver resected demonstrated no evidence of steatohepatitis from the irinotecan arterial infusion. Conclusions: Hepatic arterial infusion irinotecan drug-eluting beads is safe and effective in pre-surgical therapy and helpful in evaluating the biology of metastatic colorectal cancer to the liver prior to planned hepatic

    Objectives To review the Yorkshire Laser Centre experience with bronchoscopic photodynamic therapy (PDT) in early central lung cancer in subjects not eligible for surgery and to discuss diagnostic problems and the indications for PDT in such cases. Methods Of 200 patients undergoing bronchoscopic PDT, 21 had early central lung cancer and were entered into a prospective study. Patients underwent standard investigations including white light bronchoscopy in all and autofluorescence bronchoscopy in 12 of the most recent cases. Indications for bronchoscopic PDT were recurrence/metachronous endobronchial lesions following previous treatment with curative intent in 10 patients (11 lesions), ineligibility for surgery because of poor cardiorespiratory function in 8 patients (9 lesions) and declined consent to operation in 3 patients. PDT consisted of intravenous administration of Photofrin 2 mg/kg followed by bronchoscopic illumination 24–48 h later. Results 29 treatments were performed in 21 patients (23 lesions). There was no procedure‐related or 30 day mortality. One patient developed mild skin photosensitivity. All patients expressed satisfaction with the treatment and had a complete response of variable duration. Six patients died at 3–103 months (mean 39.3), three of which were not as a result of cancer. Fifteen patients were alive at 12–82 months. Conclusion Bronchoscopic PDT in early central lung cancer can achieve long disease‐free survival and should be considered as a treatment option in those ineligible for resection. Autofluorescence bronchoscopy is a valuable complementary investigation for identification of synchronous lesions and accurate illumination in bronchoscopic PDT. PMID:17090572

    The surgical approach to treating fecal incontinence is complex. After optimal medical management has failed, surgery remains the best option for restoring function. Patient factors, such as prior surgery, anatomic derangements, and degree of incontinence, help inform the astute surgeon regarding the most appropriate option. Many varied approaches to surgical management are available, ranging from more conservative approaches, such as anal canal bulking agents and neuromodulation, to more aggressive approaches, including sphincter repair, anal cerclage techniques, and muscle transposition. Efficacy and morbidity of these approaches also range widely, and this article presents the data and operative considerations for these approaches. PMID:24280402

    Objective: To evaluate the effectiveness of surgical simulation compared with other methods of surgical training. Summary Background Data: Surgical simulation (with or without computers) is attractive because it avoids the use of patients for skills practice and provides relevant technical training for trainees before they operate on humans. Methods: Studies were identified through searches of MEDLINE, EMBASE, the Cochrane Library, and other databases until April 2005. Included studies must have been randomized controlled trials (RCTs) assessing any training technique using at least some elements of surgical simulation, which reported measures of surgical task performance. Results: Thirty RCTs with 760 participants were able to be included, although the quality of the RCTs was often poor. Computer simulation generally showed better results than no training at all (and than physical trainer/model training in one RCT), but was not convincingly superior to standard training (such as surgical drills) or video simulation (particularly when assessed by operative performance). Video simulation did not show consistently better results than groups with no training at all, and there were not enough data to determine if video simulation was better than standard training or the use of models. Model simulation may have been better than standard training, and cadaver training may have been better than model training. Conclusions: While there may be compelling reasons to reduce reliance on patients, cadavers, and animals for surgical training, none of the methods of simulated training has yet been shown to be better than other forms of surgical training.

    Many surgical revolutions distinguish the history and evolution of surgery. They come in different sizes and exert a variable effect on the development and practice of the discipline. As science and technology rapidly evolve, so too does the creation of new paradigms, ideas and innovations or discoveries for the improvement of the surgical sciences. Surgical revolutions are not new, and have existed for centuries even though they have been more frequently recognized since the middle of the 19th century, 20th century and down to the present. Surgical revolutionaries are indispensable in the conception and completion of any surgical revolution. However, scientific and technological advances have supported the culmination of each revolution. PMID:18615311

    Background: A joint analysis of data from centers involved in the Spanish Cooperative Initiative for Intraoperative Electron Radiotherapy was performed to investigate long-term outcomes of locally recurrent soft tissue sarcoma (LR-STS) patients treated with a multidisciplinary approach. Methods and Materials: Patients with a histologic diagnosis of LR-STS (extremity, 43%; trunk wall, 24%; retroperitoneum, 33%) and no distant metastases who underwent radical surgery and intraoperative electron radiation therapy (IOERT; median dose, 12.5 Gy) were considered eligible for participation in this study. In addition, 62% received external beam radiation therapy (EBRT; median dose, 50 Gy). Results: From 1986 to 2012, a total of 103 patients from 3 Spanish expert IOERT institutions were analyzed. With a median follow-up of 57 months (range, 2-311 months), 5-year local control (LC) was 60%. The 5-year IORT in-field control, disease-free survival (DFS), and overall survival were 73%, 43%, and 52%, respectively. In the multivariate analysis, no EBRT to treat the LR-STS (P=.02) and microscopically involved margin resection status (P=.04) retained significance in relation to LC. With regard to IORT in-field control, only not delivering EBRT to the LR-STS retained significance in the multivariate analysis (P=.03). Conclusion: This joint analysis revealed that surgical margin and EBRT affect LC but that, given the high risk of distant metastases, DFS remains modest. Intensified local treatment needs to be further tested in the context of more efficient concurrent, neoadjuvant, and adjuvant systemic therapy.

    Infective endocarditis of bacterial or fungal origin may arise in either the left or the right heart and can involve both natural and prosthetic valves. The diagnosis is based primarily upon clinical criteria and positive blood cultures, but serial electrocardiograms, fluoroscopy, and two-dimensional echocardiograms may also be helpful. The initial treatment should consist of antibiotic therapy and is itself often adequate in effecting cure. However, careful observation during antibiotic treatment is mandatory, since the development of congestive heart failure due to valvular obstruction or destruction can be an indication for surgical intervention. Other surgical indications include a failure to respond to antibiotic therapy, pulmonary or systemic emboli, evidence of abscess involving the valvular ring (particularly prevalent with prosthetic valve endocarditis), Brucella infection, and the onset of conduction disturbances. The goals of surgical treatment are removal of infective tissue, restoration of valve function, and correction of associated mechanical disorders. The results are surprisingly good, especially for a condition of this severity. Images Fig. 2. Fig. 3. Fig. 4. Fig. 5. Fig. 6. PMID:7065743

    The purpose of the study was to compare conventional cyclophosphamide/doxorubicin/vincristine/prednisolone (CHOP) chemotherapy with CHOP (3 courses) plus etoposide/methylprednisolone/high-dose cytarabine/cisplatin (ESHAP), high-dose therapy (HDT), and autologous peripheral blood progenitor cell transplantation (PBPCT) as front-line treatment for poor-prognosis aggressive non-Hodgkin's lymphoma (NHL). Between May 1, 1995, and April 30, 1998, 58 patients, aged 15-55 years, newly diagnosed with poor-prognosis aggressive NHL (category F-H by the Working Formulation) were enrolled. According to the age-adjusted international prognostic index, 65% of the patients were high-risk cases and 35% made up the high-intermediate group. After 3 courses of CHOP, 25 of 48 patients were randomized to continue with CHOP, and 23 were randomized to receive 2-4 cycles of ESHAP followed by HDT and PBPCT. There was no significant difference in the rate of complete remission between the two groups (36%, 95% confidence interval [CI]: 18%-57% in CHOP vs. 43%, 95% CI: 23%-65% in ESHAP/HDT) (P = 0.77). With a median follow-up duration of 39 months, the 4-year failure-free survival (FFS) was superior in the ESHAP/HDT group (38%, 95% CI: 18%-58% vs. 15%, 95% CI: 4%-32%) (P = 0.04). The disease-free survival was marginally different in favor of the ESHAP/HDT arm (90%, 95% CI: 47%-98% vs. 37%, 95% CI: 7%-69%) (P = 0.06). The 4-year overall survival between the two treatment arms was comparable (51%, 95% CI: 28%-70% for ESHAP/HDT vs. 30%, 95% CI: 13%-48% for CHOP) (P = 0.25). Treatment-related mortalities were not significantly different between both groups (17%, 95% CI: 5%-39% for ESHAP/HDT vs. 8%, 95% CI: 1%-26% for CHOP) (P = 0.41). However, only 61% of the patients assigned to the ESHAP/HDT arm underwent HDT and PBPCT. As compared with CHOP, the corporate regimen of CHOP/ESHAP/HDT seems to improve the FFS in patients with newly diagnosed, poor-prognosis aggressive NHL. PMID:11707834

    Bacterial-based therapies are emerging as effective cancer treatments and hold promise for refractory neoplasms, such as pancreatic ductal adenocarcinoma (PDAC), which has not shown significant improvement in therapy for more than 25 years. Using a novel combination of shIDO-ST, a Salmonella-based therapy targeting the immunosuppressive molecule indoleamine 2,3-dioxygenase (IDO), with an enzyme, PEGPH20, which depletes extracellular matrix hyaluronan, we observed extended survival with frequent total regression of autochthonous and orthotopic PDAC tumors. This observation was associated with migration and accumulation of activated polymorphonuclear neutrophils (PMN) from spleens into tumors, which was not seen using a scrambled control (shScr-ST). Purified splenic PMNs from PEGPH20/shIDO-ST-treated mice exhibited significant IDO knockdown and were able to kill tumor targets ex vivo through mechanisms involving FasL and serine proteases. In addition, CD8(+) T cells were observed to contribute to late control of pancreatic tumors. Collectively, our data demonstrate that entry of shIDO-ST and PMNs into otherwise impermeable desmoplastic tumors is facilitated by PEGPH20-mediated HA removal, further highlighting an important component of effective treatment for PDAC.

    This retrospective case series evaluates the outcome of 21 dogs with grade II stage 2 mast cell tumour (MCT) treated with adequate local therapy and adjuvant systemic chemotherapy (prednisone, vinblastine and CCNU). The median survival for all dogs was 1359 days (range, 188–2340). Median disease-free interval was 2120 days (149–2325 days). Dogs treated with surgery and chemotherapy had shorter survival (median, 1103 days; 188–2010 days) than those that underwent surgery, radiation therapy and chemotherapy as part of their treatment (median, 2056 days; 300–2340 days). Two patients had local recurrence in the radiation field and four patients had de novo MCT. Distant metastasis was not observed in any dogs. The results of this study suggest that, in the presence of loco-regional lymph node metastasis in grade II MCT, the use of prednisone, vinblastine and CCNU after adequate local-regional therapy can provide a median survival in excess of 40 months.

    A combined modality regimen employing induction chemotherapy with cisplatinum, bleomycin and methotrexate followed by surgery and/or radiation therapy was initiated in patients with advanced squamous cell carcinoma of the head and neck. In the first 23 patients treated with this program there was a 90% response rate to induction chemotherapy (9% CR and 81% PR). Toxicity associated with radiotherapy, but not surgery, was increased with 11 of 23 patients (48%) who experienced some toxicity during or immediately after radiotherapy. Mucositis was worse than expected and severe delayed mucositis was seen in 2 patients, one of whom required hospitalization. Late complications, possibly related to therapy included one myocardial infarction and one episode of hypoglycemia, both of which were fatal. One other patient voluntarily failed to take prescribed oral leucovorin, dying of unrescued methotrexate toxicity during adjuvant therapy, a questionable suicide. Further follow-up analysis of failure will be necessary to determine if the value of a combined modality regimen in producing an increased cure rate and long term survival will out weigh increased toxicity.

    Diffuse bleeding after chest wall and spine resection represents a major problem in General Thoracic Surgery. Several fibrin sealants (FS) have been developed over the years and their use has been gradually increasing over time, becoming an important aid to the surgeons, justifying their use across numerous fields of surgery due to its valid haemostatic properties. Among the several FS available, TachoSil® (Takeda Austria GmbH, Linz, Austria) stands out for its haemostatic and aerostatic properties, the latter being demonstrated even in high-risk patients after pulmonary resections for primary lung cancers. Several papers available in literature demonstrated TachoSil®’s effectiveness in controlling intraoperative and postoperative bleeding in different surgical branches, including hepatic and pancreatic surgery, as well as cardiac and thoracic surgery. However, the use of TachoSil® to control diffuse bleeding following major resections for advanced lung cancers, with requirement of chest wall and vertebral body resection for oncological radicality, was never published so far. In this paper, we report three cases of pulmonary lobectomy associated to chest wall resection and haemivertebrectomy for primary malignant lung neoplasms and for a recurrence of malignant solitary fibrous tumour of the pleura in which we used TachoSil©, which demonstrated its efficacy in controlling diffuse bleeding following resection.

    Epithelioid glioblastoma (GBM) and rhabdoid GBM are rare variants that are morphologically similar, but there is no consensus on the characteristics of each disease. These tumors have aggressive features of early recurrence and leptomeningeal dissemination and tend to develop in younger patients compared to typical GBM. The prognosis is normally worse than typical GBM, even with intensive chemoradiotherapy after surgical resection. Thus, accurate diagnosis and effective therapy for epithelioid/rhabdoid GBM are required. Four consecutive patients aged 16-48 years were diagnosed with epithelioid/rhabdoid GBM by pathological and immunohistochemical analysis at Yamaguchi University Hospital from 2006 to 2012. Two of these patients had relatively long-term survival (19 and 23 months after diagnosis). Two cases had a BRAF V600E mutation, whereas no ATRX mutation was present in any cases. All patients suffered leptomeningeal and/or spinal dissemination that worsened their prognosis. These results illustrate the need for a new therapeutic approach, such as molecular targeted drug therapy like BRAF inhibition, in addition to standard chemoradiotherapy for typical GBM.

    Gall-bladder visualization on oral cholecystography (OCG) is required for most non-surgical therapies of gallstones. In this study we attempted to establish sonographic criteria which will predict non-visualization of the gall-bladder on OCG. For this purpose we compared the results of ultrasound (US) and OCG in 171 patients with gallstones being assessed for non-surgical therapy. Sonographic criteria for non-visualization were a contracted gall-bladder and stone impaction in the gall-bladder neck or cystic duct. In detecting findings which predict non-visualization on OCG, US had a sensitivity of 78.3% and a specificity of 97.6%. The predictive values were: positive findings 92.3% and negative findings 92.4%. The overall accuracy was 92.4%. We conclude that US can be used as a first step in selecting patients for non-surgical therapy and if US indicates a contracted gall-bladder, 11% of the patients can be excluded from further diagnostic imaging.

    Fibrolamellar variant of hepatocellular carcinoma (FLHCC) does not have a favorable prognosis than conventional HCC, and there is no difference regarding the response to chemotherapy and the degree of surgical resectability. FLHCC commonly recurs after complete surgical resection, and there is a high rate of lymph node metastases. Herein, we report a 12-year-old girl with metastatic FLHCC with multiple recurrences aggressively treated with surgery, chemotherapy, and antiangiogenic agents. She is in complete remission after 4 years and 2 months after the diagnosis of metastatic FLHCC. The standard treatment of FLHCC is excision of the primary tumor and its metastases. Chemotherapy for FLHCC is controversial, and it has been suggested that cytoreductive chemotherapy was ineffective and adjuvant chemotherapy did not improve survival. Our patient with multiple recurrences was successfully treated with surgery, first-line chemotherapy with cisplatin and doxorubicin, second-line chemotherapy with 5-fluorouracil/interferon-α combination, and adjuvant antiangiogenic agents like cyclophosphamide and thalidomide. As FLHCC patients have no underlying liver disease, they can tolerate higher doses of chemotherapy compared with conventional HCC patients. We support the use of repeated aggressive surgery with adjuvant chemotherapy and antiangiogenic therapy, which provided complete remission in our patient with metastatic and recurrent FLHCC.

    Hiliar cholangiocarcinoma is the most common type of cholangiocarcinoma, an represent around 10% of all hepatobiliary tumors. It is an aggressive malignancy, resectable in around 47% of the patients at diagnosis. Complete resection is the most effective and only potentially curative therapy, with a survival rate of less than 12 months in unresectable cases. Axial computerized tomography and magnetic resonance are the most useful image techniques to determine the surgical resectability. Clinically, jaundice and pruritus are the most common symptoms at diagnosis;preoperative biliary drainage is recommended using endoscopic retrograde cholangiography or percutaneous transhepatic cholangiography. Surgery using extended liver resections with an en bloc resection of the liver with vascular reconstruction is the technique with the highest survival. Complete resection with histologically negative resection margins (R0), nodal involvement and metastases are the most important prognostic factors. PMID:26298684

    Anogenital warts (condyloma acuminatum or venereal warts) are a common sexually transmitted disease in males and females. Common clinical treatment of anogenital warts is conservative, however, in extreme cases conservative therapy is insufficient and surgical excision is required. Giant condyloma acuminata (Buschke-Löwenstein tumour) is an extremely rare clinical type of genital wart, characterised by aggressive down growth into underlying dermal structures. A 55-year-old female presented with cauliflower-like growth over the anogenital and sacral region, earlier diagnosed as condyloma acuminatum which was resistant to conservative therapy. During the period between 2005 and 2008 the patient underwent five surgical procedures. Due to the size and location of the tumour, gynaecological and plastic surgeons were involved in the procedures. In addition, definitive histology examination identified a superficial vulvar carcinoma. PMID:23420321

    Atypical wounds are probably the most delicate modern medicine topics as well as the most demanding surgical issue. Recently, we submitted an original report of two similar atypical vascular cases at our surgery department. Both presented a rare type of atypical, potentially fatal, vascular illness due to acute ischemic subcutaneous arteriolosclerosis. Because of the strikingly similar common pathophysiological features, Martorell hypertensive ischemic leg ulcer (HYTILU) and calciphylaxis require identical approach and therapy, both systemic and surgical. Even an experienced clinician can easily confuse it with other atypical wounds, namely pyoderma gangrenosum, which due to the corticosteroid induced immunodeficiency can be detrimental, since the two different approach strategies are required. Based on typical localization, necrotic painful skin necroses, progressive local deterioration, often difficult secondary infections along with long term hypertension and diabetes history could elucidate suspicion of ischemic subcutaneous arteriosclerosis. Hypertension (and often diabetes), local findings and histologically proven subcutaneous arteriolosclerosis are mandatory to make the diagnosis. Rapid local amelioration following correct treatment approach additionally confirms the presumed diagnosis. Besides the minutely repetitive surgical debridement, negative wound pressure therapy and split skin transplantation, one should consider systemic medication (analgesics, antioxidants, LMWH, sodium thiosulfate and antibiotics). Considering the cases presented, opportune decisions along with moderate aggressive and modern holistic surgical approach should inevitably resolve hard to heal atypical wounds. PMID:23193838

    Hepatocellular carcinoma (HCC) is an aggressive tumor that often occurs in the setting of chronic liver disease. Many patients do not initially manifest any symptoms of HCC and present late when cure with surgical resection or transplantation is no longer possible. For this reason, patients at high risk for developing HCC are subjected to frequent screening processes. The surgical management of HCC is complex and requires an inter-disciplinary approach. Hepatic resection is the treatment of choice for HCC in patients without cirrhosis and is indicated in some patients with early cirrhosis (Child-Pugh A). Liver transplantation has emerged in the past decade as the standard of care for patients with cirrhosis and HCC meeting Milan criteria and in select patients with HCC beyond Milan criteria. Loco-regional therapy with transarterial chemoembolization, transarterial embolization, radiofrequency ablation and other similar local treatments can be used as neo-adjuvant therapy to downstage HCC to within Milan criteria or as a bridge to transplantation in patients on transplant wait list.

    There is an urgent need to develop alternative therapies against lethal pancreatic cancer (PC). Ocimum sanctum (“Holy Basil”) has been used for thousands of years in traditional Indian medicine, but its anti-tumorigenic effect remains largely unexplored. Here, we show that extracts of O. sanctum leaves inhibit the proliferation, migration, invasion, and induce apoptosis of PC cells in vitro. The expression of genes that promote the proliferation, migration and invasion of PC cells including activated ERK-1/2, FAK, and p65 (subunit of NF-κB), was downregulated in PC cells after O. sanctum treatment. Intraperitoneal injections of the aqueous extract significantly inhibited the growth of orthotopically transplanted PC cells in vivo (p<0.05). Genes that inhibit metastasis (E-cadherin) and induce apoptosis (BAD) were significantly upregulated in tumors isolated from mice treated with O. sanctum extracts, while genes that promote survival (Bcl-2 and Bcl-xL) and chemo/radiation resistance (AURKA, Chk1 and Survivin) were downregulated. Overall, our study suggests that leaves of O. sanctum could be a potential source of novel anticancer compounds in the future. PMID:23523869

    Melanomais one of the most dreaded and aggressive neoplasms, being derived from epidermal melanocytes. The majority of melanomas are seen to involve the skin, and primary mucosal melanomas account for less than 1% of all melanomas. Oral malignant melanomas (OMM) are asymptomatic at the initial presentation, but later they become painful with growth and expansion. In the late stages, the patient may present with ulceration, bleeding, tooth mobility, paresthesia, ill-fitting prosthesis, and delayed healing of the extraction sockets. Diagnosis is often delayed due to asymptomatic clinical presentation, with silent progression of the lesion. OMM are associated with poor prognosis due to their invasive and metastasizing tendencies. The condition has poor survival rates, and metastatic melanomas show even worse prognosis. The 5-year survival rate for OMM ranges 4.5–29%, with 18.5 months being the mean survival rate. The tumor is best managed by wide surgical resection; however, consideration should also be made for adjunctive therapies such as chemotherapy, immunotherapy, and radiotherapy. Recurrences may be seen even 10–15 years after the primary therapy. This paper aims to present an interesting report of aggressive OMM in a 50-year-old male patient and emphasizes the role of dental professionals in maintaining a high degree of vigilance for the pigmented lesions of the oral cavity. Pigmented lesions of uncertain origin should be routinely biopsied to rule out malignancy. Early diagnosis of this dreadful entity entails thorough history taking, physical examination, and radiographic features coupled with histopathology. PMID:27114959

    A persistently positive positron emission tomography (PET) scan during therapy for diffuse large B-cell lymphoma (DLBCL) is predictive of treatment failure. A response-adapted strategy consisting of an early treatment change to four cycles of R-ICE (rituximab, ifosfamide, carboplatin, etoposide) was studied in the Eastern Cooperative Oncology Group E3404 trial. Previously untreated patients with DLBCL stage III, IV, or bulky II, were eligible. PET scan was performed after 3 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and scored as positive or negative by central review during the fourth cycle. PET-positive patients received 4 cycles of R-ICE, PET-negative patients received 2 more cycles of R-CHOP. A ≥45% 2-year progression-free survival (PFS) for mid-treatment PET-positive patients was viewed as promising. Of 74 patients, 16% were PET positive, 79% negative. The PET positivity rate was much lower than the 33% expected. Two-year PFS was 70%; 42% (90% confidence interval [CI], 19-63%) for PET-positives and 76% (90% CI 65-84%) for PET-negatives. Three-year overall survival (OS) was 69% (90% CI 43-85%) and 93% (90% CI 86-97%) for PET-positive and –negative cases, respectively. The 2-year PFS for mid-treatment PET-positive patients intensified to R-ICE was 42%, with a wide confidence interval due to the low proportion of positive mid-treatment PET scans. Treatment modification based on early PET scanning should remain confined to clinical trials. PMID:25823885

    Purpose 25% of all lung cancer cases are neuroendocrine (NELC) including typical (TC) and atypical carcinoid (AC), large-cell neuroendocrine (LCNEC) and small cell lung cancer (SCLC). Prognostic and predictive biomarkers are lacking. Experimental Design Sixty patients were used for nCounter mRNA expression analysis of the folic-acid metabolism (ATIC, DHFR, FOLR1, FPGS, GART, GGT1, SLC19A1, TYMS) and DNA-repair (ERCC1, MLH1, MSH2, MSH6, XRCC1). Phenotypic classification classified tumors (either below or above the median expression level) with respect to the folic acid metabolism or DNA repair. Results Expression of FOLR1, FPGS, MLH1 and TYMS (each p<0.0001) differed significantly between all four tumor types. FOLR1 and FPGS associated with tumor differentiation (both p<0.0001), spread to regional lymph nodes (FOLR1 p=0.0001 and FPGS p=0.0038), OS and PFS (FOLR1 p<0.0050 for both and FPGS p<0.0004 for OS). Phenotypic sorting revealed the Ft-phenotype to be the most prominent expression profile in carcinoids, whereas SCLC presented nearly univocal with the fT and LCNEC with fT or ft. These results were significant for tumor subtype (p<0.0001). Conclusions The assessed biomarkers and phenotypes allow for risk stratification (OS, PFS), diagnostic classification and enhance the biological understanding of the different subtypes of neuroendocrine tumors revealing potential new therapy options and clarifying known resistance mechanisms.

    Dedifferentiated chordoma is a rare, aggressive, chemoresistant and radioresistant malignancy arising from notochord remnants that can occur anywhere along the spine. Incidence in patients under 20 years of age is 1 per 250 million. We report a case of dedifferentiated clival chordoma presenting in a 3-year-old boy with pulmonary metastasis, which responded unusually well to chemotherapy, achieving complete metastatic clearance and debulking of the primary tumour. Proton beam therapy achieved further tumour control, with excellent quality of life for multiple years. On disease relapse, an atypical lateral transcondylar surgical approach achieved complete macroscopic clearance but there was cutaneous seeding. This, and continued primary site activity, failed to be controlled with targeted therapy, traditional chemotherapy and photon radiation, resulting in gradual neurological decline and death. Intensive management resulted in above-average survival despite diagnosis late in the disease course, which may be of value directing investigation into optimal management. PMID:27284102

    Purpose To investigate whether parents’ previous physical aggression (PPA) exhibited during early adolescence is associated with adolescents’ subsequent parent-directed aggression even beyond parents’ concurrent physical aggression (CPA); to investigate whether adolescents’ emotion dysregulation and attitudes condoning child-to-parent aggression moderate associations. Methods Adolescents (N = 93) and their parents participated in a prospective, longitudinal study. Adolescents and parents reported at waves 1–3 on four types of parents’ PPA (mother-to-adolescent, father-to-adolescent, mother-to-father, father-to-mother). Wave 3 assessments also included adolescents’ emotion dysregulation, attitudes condoning aggression, and externalizing behaviors. At waves 4 and 5, adolescents and parents reported on adolescents’ parent-directed physical aggression, property damage, and verbal aggression, and on parents’ CPA Results Parents’ PPA emerged as a significant indicator of adolescents’ parent-directed physical aggression (odds ratio [OR]: 1.25, 95% confidence interval [CI]: 1.0–1.55; p = .047), property damage (OR: 1.29, 95% CI: 1.1–1.5, p = .002), and verbal aggression (OR: 1.35, 95% CI: 1.15–1.6, p < .001) even controlling for adolescents’ sex, externalizing behaviors, and family income. When controlling for parents’ CPA, previous mother-to-adolescent aggression still predicted adolescents’ parent-directed physical aggression (OR: 5.56, 95% CI: 1.82–17.0, p = .003), and father-to-mother aggression predicted adolescents’ parent-directed verbal aggression (OR: 1.86, 95% CI: 1.0–3.3, p = .036). Emotion dysregulation and attitudes condoning aggression did not produce direct or moderated effects. Conclusions Adolescents’ parent-directed aggression deserves greater attention in discourse about lasting, adverse effects of even minor forms of parents’ physical aggression. Future research should investigate parent-directed aggression as

    A prospective trial was performed to evaluate the recurrence rate and 5-year disease-free survival rate in patients with surgical Stage I endometrial adenocarcinoma. Patients with Stage I, Grade 1 or 2 disease, less than 50% myometrial invasion, and no evidence of disease outside the corpus of the uterus were treated by hysterectomy and bilateral salpingo-oophorectomy and postoperative vaginal radium/cesium (Group 1). Patients with surgical Stage I, Grade 3 disease or deep myometrial invasion, and histologically negative paraaortic lymph nodes were treated with postoperative pelvic radiation therapy (5000-5040 cGY) (Group 2). Patients with malignant peritoneal cytologic findings also received progesterone therapy. Of the 92 Group 1 patients, there have been no recurrences and the 5-year estimated disease-free survival rate was 99%. Of the 41 Group 2 patients, there have been four (9.7%) recurrences but only one (2.4%) within the treated field (pelvis), and the 5-year estimated disease-free survival rate was 88%. Of the 133 patients, the 5-year estimated disease-free survival rate was 96%, and only one patient (0.7%) had a local pelvic recurrence. Of the 16 patients with malignant peritoneal cytologic findings who were treated with progesterone therapy, none has had a recurrence.

    2014-06-01

    For decades, Aggregatibacter actinomycetemcomitans has been considered the most likely etiologic agent in aggressive periodontitis. Implementation of DNA-based microbiologic methodologies has considerably improved our understanding of the composition of subgingival biofilms, and advanced open-ended molecular techniques even allow for genome mapping of the whole bacterial spectrum in a sample and characterization of both the cultivable and not-yet-cultivable microbiota associated with periodontal health and disease. Currently, A. actinomycetemcomitans is regarded as a minor component of the resident oral microbiota and as an opportunistic pathogen in some individuals. Its specific JP2 clone, however, shows properties of a true exogenous pathogen and has an important role in the development of aggressive periodontitis in certain populations. Still, limited data exist on the impact of other microbes specifically in aggressive periodontitis. Despite a wide heterogeneity of bacteria, especially in subgingival samples collected from patients, bacteria of the red complex in particular, and those of the orange complex, are considered as potential pathogens in generalized aggressive periodontitis. These types of bacterial findings closely resemble those found for chronic periodontitis, representing a mixed polymicrobial infection without a clear association with any specific microorganism. In aggressive periodontitis, the role of novel and not-yet-cultivable bacteria has not yet been elucidated. There are geographic and ethnic differences in the carriage of periodontitis-associated microorganisms, and they need to be taken into account when comparing study reports on periodontal microbiology in different study populations. In the present review, we provide an overview on the colonization of potential periodontal pathogens in childhood and adolescence, and on specific microorganisms that have been suspected for their role in the initiation and progression of aggressive

    A 34 years old male patient was referred to our clinic for restorative dental treatment. During detailed consultation and dental examination a relatively rare form of periodontal disease had been diagnosed. Intraoral examination included recording of dental and periodontal status. Based on patient's dental history, measurements of probing pocket depths (PPD), clinical attachment level (CAL), and also the X-ray findings, Localized Aggressive Periodontitis (LAP) unknown by the patient was diagnosed. After patient's consent the comprehensive treatment plan covered the dental prevention, periodontal non-surgical and surgical therapy and rehabilitation. The treatment started with oral hygienic instruction, motivation then supra- and subgingival scaling and rootplaning. Later extraction and elective root canal treatment were performed, followed by open flap periodontal surgery combined with hemisection of two molars. After a full mouth conservative restorative therapy, function and esthetics were restored by fix dental prostheses.

    Complementary and Alternative Therapies (CAT) are increasingly being utilized in conjunction with conventional medicine. Health Information Technology (HIT) and CAT are being scrutinized for evidence based health outcomes. The aim of this randomized controlled trial (RCT) is to determine if the use of mobile technologies delivering CAT, specifically relaxation technique (RT), medical music intervention (MMI), nature landscape applications with (NLAM) and without music (NLAWM) compared with no intervention (control group) will assist in decreasing pre- and post-surgical patients' anxiety and pain levels while increasing post-operative healing self-efficacy levels.

    The prognosis of patients with lung cancer metastasis to the spine is poor, and the choice of surgery is questionable based on the aggressiveness of the disease. The present study describes a case of a 56-year-old male with metastatic spinal cord compression. The patient underwent surgery for posterior decompression and internal fixation, in addition to receiving postoperative radiation and epidermal growth factor receptor (EGFR) inhibitor medication. After 24 months, positron emission tomography-computed tomography scan showed a reduction in the left upper lobe mass in the short axis and inactivation of the neoplasm in the left upper lobe and T9 vertebra. Based on these promising results, it is suggested that orthopedic oncologists consider the combination of radiation and EGFR inhibitor therapy with surgery for the treatment of lung cancer metastasis to the spine.

    Aggressive non-Hodgkin's lymphona include diffuse large B-cell lymphoma, anaplastic large cell lymphona, and different peripheral T-cell lymphomas. An international prognostic index has been developed including age, serum LDH, performance status, and extranodal involvement. For localized aggressive lymphoma, the preferred treatment is 3-4 CHOP and radiation therapy, with a cure rate of 70-80%. For disseminated aggressive lymphoma, current regimens have a cure rate of less than 40%. Innovative strategies, including dose escalation, autologus stem cell support, new drugs, and immunotherapy are being explored to improve these results. PMID:10863150

    Background Neoadjuvant chemotherapy (NCT) down-stages advanced primary tumors, with magnetic resonance imaging (MRI) being the most sensitive imaging predictor of response. However, the impact of MRI evaluation on surgical treatment decisions in the neoadjuvant setting has not been well described. We report surgical patterns of care across 8 National Cancer Institute comprehensive cancer centers in women receiving both NCT and MRI to evaluate the impact of MRI findings on surgical planning. Methods Seven hundred seventy women from 8 institutions received NCT with MRI obtained both before and after systemic treatment. Univariate and multivariate analyses of imaging, patient-, and tumor-related covariates associated with choice of breast surgery were conducted. Results MRI and surgical data were available on 759 of 770 patients. A total of 345 of 759 (45 %) patients received breast-conserving surgery and 414 of 759 (55 %) received mastectomy. Mastectomy occurred more commonly in patients with incomplete MRI response versus complete (58 vs. 43 %) (p = 0.0003). On multivariate analysis, positive estrogen receptor status (p = 0.02), incomplete MRI response (p = 0.0003), higher baseline T classification (p < 0.0001), younger age (p < 0.0006), and institution (p = 0.003) were independent predictors of mastectomy. A statistically significant trend toward increasing use of mastectomy with increasing T stage at presentation (p < 0.0001) was observed in patients with incomplete response by MRI only. Among women with complete response on MRI, 43 % underwent mastectomy. Conclusions Within a multi-institutional cohort of women undergoing neoadjuvant treatment for breast cancer, MRI findings were not clearly associated with extent of surgery. This study shows that receptor status, T stage at diagnosis, young age, and treating institution are more significant determinants of surgical treatment choice than MRI response data. PMID:25059792

    Abstract Objective: This article examines the characteristics of impulsive aggression (IA) as a comorbidity in children and adolescents with attention-deficit/hyperactivity disorder (ADHD), focusing on its incidence, impact on ADHD outcomes, need for timely intervention, and limitations of current treatment practices. Methods: Relevant literature was retrieved with electronic searches in PubMed and PsycINFO using the search strategy of “ADHD OR attention deficit hyperactivity disorder” AND “impulsive aggression OR reactive aggression OR hostile aggression OR overt aggression” AND “pediatric OR childhood OR children OR pre-adolescent OR adolescent” with separate searches using review OR clinical trial as search limits. Key articles published before the 2007 Expert Consensus Report on IA were identified using citation analysis. Results: More than 50% of preadolescents with ADHD combined subtype reportedly display clinically significant aggression, with impulsive aggression being the predominant subtype. Impulsive aggression is strongly predictive of a highly unfavorable developmental trajectory characterized by the potential for persistent ADHD, increasing psychosocial burden, accumulating comorbidities, serious lifelong functional deficits across a broad range of domains, delinquency/criminality, and adult antisocial behavior. Impulsive aggression, which triggers peer rejection and a vicious cycle of escalating dysfunction, may be a key factor in unfavorable psychosocial outcomes attributed to ADHD. Because severe aggressive behavior does not remit in many children when treated with primary ADHD therapy (i.e., stimulants and behavioral therapy), a common practice is to add medication of a different class to specifically target aggressive behavior. Conclusions: Impulsive aggression in children and adolescents with ADHD is a serious clinical and public health problem. Although adjunctive therapy with an aggression-targeted agent is widely recommended when

    Breast cancer is the most common malignancy in Polish women. Management of breast cancer includes surgical treatment as well as adjuvant chemotherapy, radiotherapy, hormonal therapy, and combination regimens. One of the adverse consequences of oncological management of breast cancer may involve changes in frontal plane body posture. The objective of the study was to assess the frontal plane body posture changes in women treated for breast cancer. A prospective study including 101 of female breast cancer patients subjected to surgical treatment in the period from October 2011 to October 2012 (mastectomy was performed in 51 cases while breast conserving therapy was administered in the remaining 50 cases). The body posture in the frontal plane was assessed using the computer-assisted postural assessment system with Moiré fringe analysis. No statistically significant differences were observed in pre-operational postural parameters of interest. Exam II revealed highly significant differences in SLA values; results suggesting more pronounced dysfunction were observed in the MAS group. Exam III revealed highly significant differences in PIA, SH, SD and SLA values; results suggesting more pronounced dysfunction were observed in the MAS group. Undesirable postural changes occur both in women who were treated with radical mastectomy and in those who underwent breast-conserving surgery; breast-conserving surgery is associated with decreased severity in postural abnormalities.

    Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors’ experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan. PMID:27336736

    Normative beliefs have been defined as self-regulating beliefs about the appropriateness of social behaviors. In 2 studies the authors revised their scale for assessing normative beliefs about aggression, found that it is reliable and valid for use with elementary school children, and investigated the longitudinal relation between normative beliefs about aggression and aggressive behavior in a large sample of elementary school children living in poor urban neighborhoods. Using data obtained in 2 waves of observations 1 year apart, the authors found that children tended to approve more of aggression as they grew older and that this increase appeared to be correlated with increases in aggressive behavior. More important, although individual differences in aggressive behavior predicted subsequent differences in normative beliefs in younger children, individual differences in aggressive behavior were predicted by preceding differences in normative beliefs in older children.

    We investigated the effects of group music intervention on aggression and self-esteem in children with highly aggressive behavior. Forty-eight children were allocated to either a music intervention group or an untreated control group. The music intervention group received 50 min of music intervention twice weekly for 15 consecutive weeks. The outcome measures were Child Behavior Checklist Aggression Problems Scale (Parents), Child Aggression Assessment Inventory (Teachers) and Rosenberg Self-esteem Scale. After 15 weeks, the music intervention group showed significant reduction of aggression and improvement of self-esteem compared with the control group. All outcome measures were significantly lower in the music intervention group than prior to treatment, while there was no change in the control group. These findings suggest that music can reduce aggressive behavior and improve self-esteem in children with highly aggressive behavior. Music intervention is an easily accessible therapy for children and as such may be an effective intervention for aggressive behavior. Further more, objective and replicable measures are required from a randomized controlled trial with a larger sample size and active comparable control. PMID:18955314

    Adjuvant chemotherapy is commonly given to surgically treated non-small-cell lung cancer (NSCLC) patients. However, the prerequisite for chemotherapy needs to be scrutinized in order to maximize the benefits to patients. In this study, we observed that NSCLC cells with high Id1 protein expression were vulnerable to the treatment of paclitaxel and cisplatin. In addition, paclitaxel and cisplatin caused Id1 protein degradation through ubiquitination. In the nude mice xenograft model, the tumor growth was reduced to a large degree in the Id1-overexpressing group upon treatment with paclitaxel and cisplatin. Furthermore, immunohistochemical staining for Id1 followed by Kaplan-Meier survival analysis showed that surgically treated NSCLC patients with high Id1 expression in primary tumor tissues had better disease-free and overall survivals after adjuvant paclitaxel and cisplatin chemotherapy. In summary, our current data suggest that Id1, a generally negative prognostic factor, predicts a favorable prognosis in the case of surgically treated NSCLC patients receiving the definitive adjuvant chemotherapy. The distinct role of Id1 reported in this study may arise from the phenomenon of Id1 dependence of NSCLC cells for survival, which renders the cancer cells additionally susceptive to the adjuvant chemotherapy with paclitaxel and cisplatin.

    Diabetes is a well-known risk factor for invasive mucormycosis with rhinocerebral involvement. Acute necrosis of the maxilla is seldom seen and extensive facial bone involvement is rare in patients with rhino-orbital-cerebral mucormycosis. An aggressive surgical approach combined with antifungal therapy is usually necessary. In this report, we describe the successful, personalized medical and surgical management of extensive periorbital mucormycosis in an elderly diabetic, HIV-negative woman. Mono- or combination therapy with liposomal amphotericin B (L-AmB) and posaconazole (PSO) and withheld debridement is discussed. The role of aesthetic plastic surgery to preserve the patient's physical appearance is also reported. Any diabetic patient with sinonasal disease, regardless of their degree of metabolic control, is a candidate for prompt evaluation to rule out mucormycosis. Therapeutic and surgical strategies and adjunctive treatments are essential for successful disease management. These interventions may include combination therapy. Finally, a judicious multimodal treatment approach can improve appearance and optimize outcome in elderly patients. PMID:24982678

    The incidence of thyroid cancer is increasing rapidly. A large percentage of new cases identified fall into a low-risk category. As the incidence has increased, clinical experience has confirmed that the majority of patients will have excellent outcomes and that those at risk of doing badly can be reliably identified. Treatment for thyroid cancer is predominantly surgical. The decision about how aggressively this disease should be managed has remained controversial due to the excellent outcomes irrespective of the nature of surgical procedure chosen. This article reviews the developments in our understanding of the biology of thyroid cancer and the evidence that supports the approach to management. PMID:26918146

    Patients with diabetes have a high risk of surgical site infection (SSI) after ankle surgery. The aim of the present study was to investigate the efficacy of vacuum-assisted closure (VAC) in the prevention of SSI after ankle surgery compared with the efficacy of standard moist wound care (SMWC). A retrospective study was performed of unstable ankle fractures for surgical fixation in patients with diabetes from January 2012 to December 2014. VAC and SMWC were used for surgical incision coverage. The primary outcome was the incidence of SSI, and the secondary outcomes were the length of hospital stay and crude hospital costs. The data from 76 patients were analyzed, with 22 (28.95%) in the VAC group and 54 (71.05%) in the SMWC group. The incidence of SSI was 4.6% in the VAC group compared with 27.8% in the SMWC group (chi-square 5.076; p = .024), and the crude odds ratio for SSI in the VAC group was 0.124 (95% confidence interval 0.002 to 0.938). The length of hospital stay was lower in the VAC group than in the SMWC group (12.6 ± 2.7 days and 15.2 ± 3.5 days, respectively; t = 3.122, p = .003). The crude hospital costs were also lower in the VAC group than in the SMWC group (Chinese yuan 8643.2 ± 1195.3 and 9456.2 ± 1106.3, respectively; t = 2.839, p = .006). After logistic regression analysis, the adjusted odds ratio for the total SSI rate comparing VAC and SMWC was 0.324 (95% confidence interval 0.092 to 0.804; p = .021). Compared with SMWC, VAC can decrease the SSI rate after ankle surgery in patients with diabetes. This finding should be confirmed by prospective, randomized controlled clinical trials. PMID:26603948

    Aggressive behavior in schizophrenic patients can often be problematic not only for the patients themselves, but for their families and others. This study examined the effect of electroconvulsive therapy (ECT) in combination with risperidone in an open trial in 10 male schizophrenic patients with significant aggressive behaviors. Patients were given bilateral ECT five times a week in combination with risperidone. The mean total number of times of ECT was 6.6 (range 5-9). The aggressive behavior in five of the six patients, who showed positive symptoms, was rapidly ameliorated within 12 days. The ECT/risperidone regimen also eliminated aggressive behavior in four patients showing no positive symptoms within 10 days. These treatment effects lasted for at least 6 months in 9 (of the 10) patients. The results suggest that ECT, combined with risperidone, produce a rapid and effective elimination of aggressive behaviors in schizophrenic patients. In addition, there was a resolution of aggression in four patients with no positive symptoms. This suggests that aggression in some schizophrenic patients develops as a primary symptom of schizophrenia and is not related to other positive symptoms of the disease or the patient's personality traits.

  17. The nature of human aggression.

    PubMed

    Archer, John

    2009-01-01

    Human aggression is viewed from four explanatory perspectives, derived from the ethological tradition. The first consists of its adaptive value, which can be seen throughout the animal kingdom, involving resource competition and protection of the self and offspring, which has been viewed from a cost-benefit perspective. The second concerns the phylogenetic origin of aggression, which in humans involves brain mechanisms that are associated with anger and inhibition, the emotional expression of anger, and how aggressive actions are manifest. The third concerns the origin of aggression in development and its subsequent modification through experience. An evolutionary approach to development yields conclusions that are contrary to the influential social learning perspective, notably that physical aggression occurs early in life, and its subsequent development is characterized by learned inhibition. The fourth explanation concerns the motivational mechanisms controlling aggression: approached from an evolutionary background, these mechanisms range from the inflexible reflex-like responses to those incorporating rational decision-making.

    2005-04-01

    Many studies have demonstrated that boys are more aggressive than girls (see J. D. Coie & K. Dodge, 1997, for a review) and that emotion regulation difficulties are associated with problematic behaviors (N. Eisenberg & R. A. Fabes, 1999; M. Gilliom, D. S. Shaw, J. E. Beck, M. A. Schonberg, & J. L. Lukon, 2002). However, recent findings indicate that gender differences in aggressive behaviors disappear when assessments are broadened to include relational aggression--behaviors designed to harm the relationship goals of others by spreading rumors, gossiping, and eliciting peer rejection of others. Moreover, although difficulties regulating emotions have been reported for physically aggressive children, little research has examined these processes in relationally aggressive children. This article argues that investigation into the associations between emotion regulation and relational aggression is a critical direction for future research on the etiology and prevention of mental health problems in girls.

    Gastric cancer patients with main portal vein tumor thrombus usually have a short survival time, owing to its aggressive behavior. Herein, we report a long-surviving case of gastric cancer with main portal vein tumor thrombus. A 78-year-old man presenting with anorexia and body weight loss was diagnosed with gastric cancer. The patient was referred to our hospital for further examination and treatment. Endoscopy revealed a type 3 tumor (8.0 cm in length) in the body of the stomach. Biopsy led to the diagnosis of moderately differentiated adenocarcinoma. Enhanced computed tomography revealed a large tumor thrombus extending from the gastric coronary vein to the portal trunk. A total gastrectomy with lymphadenectomy, splenectomy, and thrombectomy was performed. Postoperative chemotherapy with S-1 was administered for 18 months. The patient died a natural death without recurrence at 49 postoperative months. To the best of our knowledge, the patient was the oldest to be diagnosed with gastric cancer with main portal vein tumor thrombus at diagnosis, who survived >36 months. Although gastric cancer with main portal vein tumor thrombus is a rare occurrence, its prognosis is extremely poor. Intensive surgery and long-term chemotherapy may be effective at improving survival time in these patients. PMID:27318995

    Studies from several countries, representing diverse cultures, have reported an association between violent suicide attempts by patients with unipolar depression and personality disorders and low concentrations of the major serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid (CSF). Related investigations have documented a similar inverse correlation between impulsive, externally directed aggressive behavior and CSF 5-HIAA in a subgroup of violent offenders. In these individuals, low CSF 5-HIAA concentrations are also associated with a predisposition to mild hypoglycemia, a history of early-onset alcohol and substance abuse, a family history of type II alcoholism, and disturbances in diurnal activity rhythm. These data are discussed in the context of a proposed model for the pathophysiology of a postulated "low serotonin syndrome." PMID:1385390

    Sarcomas are rare cancers of mesenchymal cell origin that include many histologic subtypes and molecularly distinct entities. For primary resectable sarcoma, surgery is the mainstay of treatment. Despite treatment, approximately 50% of patients with soft tissue sarcoma are diagnosed with or develop distant metastases, significantly affecting their survival. Although systemic therapy with conventional chemotherapy remains the primary treatment modality for those with metastatic sarcoma, increased survival has been achieved in select patients who receive multimodality therapy, including surgery, for their metastatic disease. This article provides an overview of the literature on surgical management of pulmonary and hepatic sarcoma metastases. PMID:27542649

    1998-01-01

    Eleven participants carried out a study of aggression by utilizing clinical data from the analyses of patients who manifested significant problems in the management of aggression. The purpose of the study was to increase understanding of the intrapsychic factors that determine the nature and intensity of aggressive tendencies, the place they occupy in the psychic economy, their patterns of expression, and the extrapsychic factors that trigger them. The findings of the study indicate, first, that aggression is multiply determined by developmental, genetic (experiential), and dynamic variables; second, that each cluster of variables affects the nature, intensity, and expression of aggression in a fairly specific way; third, the importance of aggression in the psychic economy is proportional to the extent to which it is overdetermined. The successful analysis of aggressive individuals depends not solely on interpretation and insight, but on the relationship to the analyst as new parent who does not threaten and prohibit. The relationship to the analyst permits developmental change, particularly the ability to organize, structure, and control aggression. As a result, it need not be expressed destructively, but may be placed in the service of constructive thought and action. PMID:9990829

    The management of retinopathy of prematurity (ROP) can be challenging in preterm babies with a gestational age <30 weeks, those with very low birth weight and multiple risk factors (eg., oxygen therapy for respiratory distress, sepsis, neonatal jaundice). A premature infant presented with "hybrid" zone 1 disease in the right eye and aggressive posterior ROP in the left eye. Both eyes were adequately treated with laser photocoagulation; however, the eyes deteriorated and progressed to stage 4 ROP. Both eyes eventually underwent intravitreal bevacizumab followed by lens sparing vitrectomy with good anatomical and visual outcome. Anticipation of progression despite laser photocoagulation in certain clinical scenarios, frequent follow-up and timely surgical intervention is paramount. PMID:26180484

    The assessment and management of tricuspid valve disease have evolved substantially during the past several years. Whereas tricuspid stenosis is uncommon, tricuspid regurgitation is frequently encountered and it is most often secondary due to annular dilatation and leaflet tethering from right ventricular remodelling. The indications for tricuspid valve surgery to treat tricuspid regurgitation are several and mainly related to the underlying disease, to the severity of insufficiency and to the right ventricular function. Surgical tricuspid repair has been avoided for years, because of the misleading concept that tricuspid regurgitation should disappear once the primary left-sided problem has been eliminated. Instead, during the last decade, many investigators have reported evidence in favor of a more aggressive surgical approach to functional tricuspid regurgitation, recognising the risk of progressive tricuspid insufficiency in patients with moderate or lesser degrees of tricuspid regurgitation and tricuspid annular dilatation. This concept, along with the long-term outcomes of principal surgical repair techniques are reported and discussed. Last, novel transcatheter therapies have begun to emerge for the treatment of severe tricuspid regurgitation in high-risk patients. Hence, very preliminary pre-clinical and clinical experiences are illustrated. The scope of this review is to explore the anatomic basis, the pathophysiology, the outcomes and the new insights in the management of functional tricuspid regurgitation. PMID:27329290

    Going beyond Winnicott's widely known ideas about creativity, in this paper the authors ask why some people are able to live creatively while others suffer recurrent feelings of anger, futility, and depression. Examining Winnicott's reframing of aggression as a life force, it attempts to answer this question by tracing the evolution of his thinking on the nature and origin of aggression. It argues that because he saw aggression as inherent and as central to emotional development, interference in its expression compromises psychic maturation. The paper explores how Winnicott arrived at the conception of a combined love-strife drive and demonstrates that for him, there is no love without aggression, no subject, no object, no reality, and no creativity. That is, for Winnicott, aggression is an achievement that leads to the capacity to live creatively and to experience authenticity. Clinical vignettes illustrate the therapeutic use of these conclusions and their value for psychoanalytic theory. PMID:12102012

    Can people develop false memories for committing aggressive acts? How does this process compare to developing false memories for victimhood? In the current research we used a simple false feedback procedure to implant false memories for committing aggressive acts (causing a black eye or spreading malicious gossip) or for victimhood (receiving a black eye). We then compared these false memories to other subjects' true memories for equivalent events. False aggressive memories were all too easy to implant, particularly in the minds of individuals with a proclivity towards aggression. Once implanted, the false memories were indistinguishable from true memories for the same events, on several dimensions, including emotional content. Implications for aggression-related memory more generally as well as false confessions are discussed. PMID:23639921

    The Implicit Association Test (IAT, Greenwald, McGhee, & Schwartz, 1998) was adapted to assess the automatically activated (implicit) self-concept of aggressiveness. In three studies the validity of the Aggressiveness-IAT (Agg-IAT) was supported by substantial correlations with self-report measures of aggressiveness. After controlling for self-report measures of aggressiveness, the Agg-IAT accounted for 9-15% of the variance of three different indicators of aggressive behavior across three studies. To further explore the nomological network around the Agg-IAT we investigated its correlations with measures of social desirability (SD). Although not fully conclusive, the results across four studies provided some support for a weak negative correlation between impression management SD and aggressive behavior as well as the Agg-IAT. This result is in line with an interpersonally oriented self-control account of impression management SD. Individuals with high SD scores seem to behave less aggressively, and to show lower Agg-IAT scores. The one-week stability of the Agg-IAT was r = .58 in Study 4. Aggr.

    The pedagogical approach to surgical training has changed significantly over the past few decades. No longer are surgical skills solely acquired through a traditional apprenticeship model of training. The acquisition of many technical and nontechnical skills is moving from the operating room to the surgical skills laboratory through the use of simulation. Many platforms exist for the learning and assessment of surgical skills. In this article, the authors provide a broad overview of some of the currently available surgical simulation modalities including bench-top models, laparoscopic simulators, simulation for new surgical technologies, and simulation for nontechnical surgical skills.

    2010-01-01

    This paper explores the challenges surgical practices face in coordinating surgeries and how the electronic surgical record management (ESRM) approach to surgical coordination can solve these problems and improve efficiency. Surgical practices continue to experience costly inefficiencies when managing surgical coordination. Application software like practice management and electronic health record systems have enabled practices to "go digital" for their administrative, financial, and clinical data. However, surgical coordination is still a manual and labor-intensive process. Surgical practices need to create a central and secure record of their surgeries. When surgical data are inputted once only and stored in a central repository, the data are transformed into active information that can be outputted to any form, letter, calendar, or report. ESRM is a new approach to surgical coordination. It enables surgical practices to automate and streamline their processes, reduce costs, and ensure that patients receive the best possible care.

    Background It is being increasingly recognised that reduced cardiorespiratory fitness is associated with poorer outcomes after major surgery. Exercise limitation and reduced aerobic capacity are common in people with end-stage liver disease. There is limited evidence about the role of exercise therapy in the management of primary biliary cirrhosis (PBC) and no studies have looked at the effect of exercise in people with PBC who are awaiting liver transplantation. This case study is the first to report that personalised exercise therapy improves cardiorespiratory fitness in a patient with PBC without worsening symptoms of severe fatigue. Methods Cardiopulmonary exercise testing was used to assess cardiorespiratory fitness in a patient with end-stage PBC prior to listing for transplantation. A personalised exercise programme was designed to improve cardiorespiratory fitness while the patient was on the transplant waiting list. Results Anaerobic threshold, VO2PEAK and maximum workload all improved with regular exercise. Fatigue levels remained unaltered. Conclusions This patient tolerated and adhered to a personalised exercise programme for a prolonged period of time while awaiting surgery despite significant fatigue and disease burden. Liver transplantation was successfully completed and this woman remains well over 2 years post-surgery. PMID:27429732

    Despite modern intensive care management, acute mediastinitis is still associated with a high morbidity and mortality (up to approximately 40 %). Effective antibiotic therapy, intensive care management, elimination of the causative sources of infection and drainage of the affected mediastinal compartments are the cornerstones of therapy in a multidisciplinary treatment concept. Early diagnosis, prompt and uncompromising initial therapy and planned computed tomography (CT) control after the first stages of therapy in order to decide on the necessity for surgical re-interventions are essential for achieving optimal results. Knowledge of the specific anatomical characteristics is crucial for the understanding of this disease and its treatment; therefore, the current knowledge on fascial layers and interstitial spaces from the neck to the mediastinum is described and discussed. A possible foudroyant spread of the infection, especially within the posterior mediastinum, has to be anticipated. The approach to the mediastinum depends on the mediastinal compartments affected, on the causative disease and on the patient's clinical situation. The surgical approach should be adapted to the particular clinical situation of the individual patient and to the surgical experience of the surgeon. When in doubt, the more invasive approach to the mediastinum, such as bilateral thoracotomy, is recommended. An ascending mediastinitis due to pancreatitis is a very rare condition; however, as chest pains are often the main clinical sign surgeons should be aware of this differential diagnosis. An intraoperative brown-black serous fluid in the mediastinal tissue is virtually pathognomonic. The treatment results of esophageal perforation as the most frequent cause of mediastinitis have been improved by integration of various interventional procedures. Hyperbaric oxygen therapy or immunoglobulin treatment can play an auxiliary role in selected patients with acute mediastinitis. PMID

    In its 3,000 years History the surgery of the Old Egypt came on to an important development. Some of the antique instruments used in traumatology, the general surgery and in cosmetic-plastic operations, are in a scarcely modified manner employed for the same purposes in modern surgical interventions nowadays. The surgical diagnostics and therapy of that time is demonstrated by the surgical instruments stock being in the possession of the "Agyptisches Museum" of the "Staatlichen Museen zu Berlin". The surgery of Egypt transferred its leading part to the prosperous medical schools of Greece at the late period of the Old Egyptian empire (1085-332 B.C.). Its surgical diagnostics and therapy depending on an empirical rationalism, the applied instruments but also its ethical attitude towards the patients have been one of the dedisive bases influencing the development of the surgery in the antiquity.

    2013-01-01

    Background Low-level laser therapy (LLLT) has been shown to modulate the inflammatory process without adverse effects , by reducing pain and swelling and promoting the repair of damaged tissues. Because pain, swelling and muscle spasm are complications found in virtually all patients following oral surgery for the removal of impacted teeth, this model has been widely used to evaluate the effects of LLLT on the inflammatory process involving bone and, connective tissue and the muscles involved in mastication. Methods/Design After meeting the eligibility criteria, 60 patients treated at a Specialty Dental Center for the removal of impacted lower third molars will be randomly divided into five groups according to the type of laser therapy used at the end of surgery (intraoral irradiation with 660 nm laser; extraoral irradiation with 660 nm laser; intraoral irradiation with 808 nm laser; extraoral irradiation with 808 nm laser and no irradiation). To ensure that patients are blinded to the type of treatment they are receiving, the hand piece of the laser apparatus will be applied both intraorally and extraorally to all participants, but the device will be turned on only at the appropriate time, as determined by the randomization process. At 2 and 7 days after surgery, the patients will be evaluated by three blinded evaluators who will measure of swelling, mouth opening (muscle spasm evaluation) and pain (using two different pain scales). The 14-item Oral Health Impact Profile (OHIP-14) will be used to assess QOL. All data will be analyzed with respect to the normality of distribution using the Shapiro-Wilk test. Statistically significant differences between the experimental groups will be determined using analysis of variance, followed by a suitable post hoc test, when necessary. The significance level will be set at α = 0.05. Discussion The lack of standardization in studies with regard to the samples, methods and LLLT parameters complicates the

    Basosquamous carcinoma is a rare cutaneous tumour that is considered an aggressive type of basal cell carcinoma with an increased risk of recurrence and metastases. This impression has been perpetuated in the literature, despite limited scientific data and conflicting results of some authors. This present study was aimed to evaluate the clinical-pathological features of this tumour and follow-up of a series of basosquamous carcinoma. Basosquamous carcinoma patients who underwent surgical excision between January 2000 and February 2012 were analyzed retrospectively. Their medical files were reviewed and the corresponding routinely stained sections (with hematoxylin-eosin) were re-evaluated by two pathologists. Thirty-five patients with basosquamous carcinoma were operated on in this period. Most tumurs were located in the head and neck area (94%), and the mean age of the patients was 69.8 years. Margin involvements were seen in 11 patients (31.4%) and all of them underwent re-excision. There was only one local recurrence. There was neither regional lymph node nor distant metastasis in this series. The recurrence rate of basosquamous carcinoma is found as 4%, lower than that of most other similar studies. Further pathologic studies are needed to better classify basosquamous carcinoma and to increase consistency between the results of studies. Surgical excision and regular follow-up are considered as the treatment of choice. PMID:25139415

    Prairie voles (Microtus ochrogaster) are socially monogamous rodents that form pair bonds—a behavior composed of several social interactions including attachment with a familiar mate and aggression toward conspecific strangers. Therefore, this species has provided an excellent opportunity for the study of pair bonding behavior and its underlying neural mechanisms. In this chapter, we discuss the utility of this unique animal model in the study of aggression and review recent findings illustrating the neurochemical mechanisms underlying pair bonding-induced aggression. Implications of this research for our understanding of the neurobiology of human violence are also discussed. PMID:22078479

In this review, we examine these myths from an evidence-based perspective, bringing greater clarity to our understanding of the predictors of workplace aggression. We conclude by pointing to the need for more research focusing on construct validity and prevention issues as well as for methodologies that minimize the likelihood of mono-method bias and that strengthen the ability to make causal inferences.

    Backgrounds/Aims Hepatic portal venous gas (HPVG) is a rare condition, with poor prognosis and a mortality rate of up to 75%. Indications for surgical and non-surgical management of HPVG including associated complications and mortality remain to be clarified. Methods From January 2008 to December 2014, 18 patients with HPVG diagnosed through abdominal computed tomography (CT) imaging were retrospectively identified. Clinical symptoms, laboratory data, underlying diseases, treatment, and mortality rate were analyzed. Patients were classified into 2 groups: surgical management recommended (SR, n=10) and conservative management (CM, n=8). The SR group was further subdivided into patients who underwent surgical management (SM-SR, n=5) and those who were managed conservatively (NS-SR, n=5). Results Conditions underlying HPVG included mesenteric ischemia (38.9%), intestinal obstruction (22.2%), enteritis (22.2%), duodenal ulcer perforation (5.6%), necrotizing pancreatitis (5.6%), and diverticulitis (5.6%). In terms of mortality, 2 patients (40%) died in the SM-SR group, 1 (12.5%) in the CM group, and 100% in the NS-SR group. Higher scores from Acute Physiology and Chronic Health Evaluation (APACHE) II predicted the mortality rates of the NS-SR and CM groups. Conclusions Identification of HPVG requires careful consideration for surgical management. If surgical management is indicated, prompt laparotomy should be performed. However, even in the non-surgical management condition, aggressive laparotomy can improve survival rates for patients with high APACHE II scores. PMID:26693238

    Benign prostatic hypertrophy (BPH) is a common cause of voiding dysfunction. BPH may lead to bladder outlet obstruction and resultant troublesome lower urinary tract symptoms. Initial management of BPH and bladder outlet obstruction is typically conservative. However, when symptoms are severe or refractory to medical therapy or when urinary retention, bladder stone formation, recurrent urinary tract infections, or upper urinary tract deterioration occur, surgical intervention is often necessary. Numerous options are available for surgical management of BPH ranging from simple office-based procedures to transurethral operative procedures and even open and robotic surgeries. This article reviews the current, most commonly used techniques available for surgical management of BPH. PMID:27261790

    PubMed

    McCarty, Mark F

    2013-10-01

    Hypoxia-inducible factor-1 (HIF-1) is a heterodimer transcription factor whose elevated activity in many cancers helps them to survive under hypoxic conditions and enhances their capacity to grow invasively, establish metastases, and survive chemo- or radiotherapy. Optimal intracellular levels of ascorbate suppress the level and transcriptional activity of HIF-1under normoxic or mildly hypoxic conditions by supporting the activity of proly and asparagyl hydroxylases that target HIF-1alpha. High intracellular ascorbate can also work in various ways to down-regulate activation of NF-kappaB which, like HIF-1 is constitutively active in many cancers and promotes aggressive behavior - in part by promoting transcription of HIF-1alpha. Yet recent evidence suggests that, even in the context of adequate ascorbate nutrition, the intracellular ascorbate content of many aggressive cancers may be supoptimal for effective HIF-1 control. This likely reflects low expression or activity of the SVCT2 ascorbate transporter. The expression of SVCT2 in cancers has so far received little study; but the extracellular acidity characteristic of many tumors would be expected to reduce the activity of this transporter, which has a mildly alkaline pH optimum. Unfortunately, since SVCT2 has a high affinity for ascorbate, and its activity is nearly saturated at normal healthy serum levels of this vitamin, increased oral administration of ascorbate would be unlikely to have much impact on the intracellular ascorbate content of tumors. However, cancers in which HIF-1 is active express high levels of glucose transporters such as GLUT-1, and these transporters can promote influx of dehydroascorbic acid (DHA) via facilitated diffusion; once inside the cell, DHA is rapidly reduced to ascorbate, which effectively is "trapped" within the cell. Hence, episodic intravenous infusions of modest doses of DHA may have potential for optimizing the intracellular ascorbate content of cancers, potentially

    Introduction Over the years, numerous trials have sufficiently documented benefits of adjuvant administration of antibiotics in combination to Scaling and Root Planing (SRP) in treatment of periodontitis. Nevertheless there are justified doubts in respect to antibiotics administration with regard to increasing development of resistances. Aim The aim of this review study and meta-analysis was to verify a possible benefit of Azithromycin (AZM) as an alternative adjuvant antibiotic in combination with SRP. Materials and Methods Electronic databases (Pubmed) were searched from the earliest point of record until May 2015. A hand search was also conducted. The variables considered in this respect were Probing Depth (PD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP) and SRP. A meta-analysis containing trials comparing SRP as a sole therapy with SRP and administration of AZM was produced once all of the data obtained had been reviewed. Results Six randomised clinical trials were accepted into the review and the meta-analysis following the process of trial selection. Meta-analysis revealed larger overall effects by the systemic administration of AZM compared with SRP on their own in terms of PD, CAL, BOP, Plaque-Index and total bacterial load reduction after three and six months. Conclusion The data used in this study revealed that the systemic administration of AZM is beneficial compared with SRP on its own for the treatment of chronic periodontitis.

    Painful callosities of the feet (PCOF) are a rare complaint in children with severe impairment of mobility and quality of life. There is no medical treatment available. We investigated the usefulness of a recently developed combined transplant technique-the sandwich transplantation with dermal collagen-elastin template in this rare condition. A 14-year-old boy suffered from PCOF for several years without any improvement by topical therapy, dermabrasion, and oral retinoids. He was unable to walk normally and suffered from severe pain. We performed a complete deep excision of the hyperkeratotic plantar tissue in general anaesthesia in combination with sandwich transplantation in the same setting. Dry sheets of collagen-elastin matrix (1 mm thickness) were placed on the soft tissue defects and covered by full-thickness mesh graft transplants from the upper leg. An individualized orthosis was produced for gait rehabilitation. Two weeks after surgery the gait-related pain was reduced remarkably. Using the orthosis, the boy was able to walk pain-free even on staircase. Surgery of PCOF with sandwich transplantation and gait rehabilitation appears to be a promising strategy for this rare condition. PMID:23378711

    Aggression is a complex behavior that influences social relationships and can be seen as adaptive or maladaptive depending on the context and intensity of expression. A model organism suitable for genetic dissection of the underlying neural mechanisms of aggressive behavior is still needed. Zebrafish has already proven to be a powerful vertebrate model organism for the study of normal and pathological brain function. Despite the fact that zebrafish is a gregarious species that forms shoals, when allowed to interact in pairs, both males and females express aggressive behavior and establish dominance hierarchies. Here, we describe two protocols that can be used to quantify aggressive behavior in zebrafish, using two different paradigms: (1) staged fights between real opponents and (2) mirror-elicited fights. We also discuss the methodology for the behavior analysis, the expected results for both paradigms, and the advantages and disadvantages of each paradigm in face of the specific goals of the study.

    Neurotensin (NT) is a versatile neuropeptide involved in analgesia, hypothermia, and schizophrenia. Although NT is released from and acts upon brain regions involved in social behaviors, it has not been linked to a social behavior. We previously selected mice for high maternal aggression (maternal defense), an important social behavior that protects offspring, and found significantly lower NT expression in the CNS of highly protective females. Our current study directly tested NT's role in maternal defense. Intracerebroventricular (i.c.v.) injections of NT significantly impaired defense in terms of time aggressive and number of attacks at all doses tested (0.05, 0.1, 1.0, and 3.0 microg). Other maternal behaviors, including pup retrieval, were unaltered following NT injections (0.05 microg) relative to vehicle, suggesting specificity of NT action on defense. Further, i.c.v. injections of the NT receptor 1 (NT1) antagonist, SR 48692 (30 microg), significantly elevated maternal aggression in terms of time aggressive and attack number. To understand where NT may regulate aggression, we examined Fos following injection of either 0.1 microg NT or vehicle. Thirteen of 26 brain regions examined exhibited significant Fos increases with NT, including regions expressing NT1 and previously implicated in maternal aggression, such as lateral septum, bed nucleus of stria terminalis, paraventricular nucleus, and central amygdala. Together, our results indicate that NT inversely regulates maternal aggression and provide the first direct evidence that lowering of NT signaling can be a mechanism for maternal aggression. To our knowledge, this is the first study to directly link NT to a social behavior. PMID:19118604

    Post-surgical surveillance of non-functioning pituitary adenoma (NFPA) is based on magnetic resonance imaging (MRI) at 3 or 6 months then 1 year. When there is no adenomatous residue, annual surveillance is recommended for 5 years and then at 7, 10 and 15 years. In case of residue or doubtful MRI, prolonged annual surveillance monitors any progression. Reintervention is indicated if complete residue resection is feasible, or for symptomatic optic pathway compression, to create a safety margin between the tumor and the optic pathways ahead of complementary radiation therapy (RT), or in case of post-RT progression. In case of residue, unless the tumor displays elevated growth potential, it is usually recommended to postpone RT until progression is manifest, as efficacy is comparable whether treatment is immediate or postponed. The efficacy of the various RT techniques in terms of tumor volume control is likewise comparable. RT-induced hypopituitarism is frequent, whatever the technique. The choice thus depends basically on residue characteristics: size, delineation, and proximity to neighboring radiation-sensitive structures. Reduced rates of vascular complications and secondary brain tumor can be hoped for with one-dose or hypofractionated stereotactic RT, but there has been insufficient follow-up to provide evidence. Somatostatin analogs and dopaminergic agonists have yet to demonstrate sufficient efficacy. Temozolomide is an option in aggressive NFPA resistant to surgery and RT. PMID:26116412

    Objective: To evaluate the variations in the detection of Porphyromonas gingivalis and/or Aggregatibacter actinomycetemcomitans before and after systemic administration of amoxicillin plus metronidazole in association with non-surgical periodontal therapy (NSPT). Background: The adjunctive use of antibiotics has been advocated to improve the clinical outcomes of NSPT. However, no systematic review has investigated the microbiological benefit of this combination. Materials and Methods: An electronic search was conducted up to December 2015. Randomized clinical trials comparing the number of patients testing positive for P. gingivalis and/or A. actinomycetemcomitans before and after NSPT with (test group) or without (control group) amoxicillin plus metronidazole were included. The difference between groups in the variation of positive patients was calculated using the inverse variance method with a random effects model. Results: The frequency of patients positive for A. actinomycetemcomitans was decreased by 30% (p = 0.002) and by 25% (p = 0.01) in the test group compared to the control group at 3- and 6-month follow-up, respectively. Similar findings were observed when considering the frequency of patients positive for Porphyromonas gingivalis, with a reduction by 28% (p < 0.0001), 32% (p < 0.0001), and 34% (p = 0.03) in the test group compared to the control group at 3-, 6-, and 12-month follow-up, respectively. Conclusion: The systemic administration of amoxicillin plus metronidazole as an adjunct to NSPT significantly decreased the number of patients positive for P. gingivalis and A. actinomycetemcomitans compared with periodontal therapy alone or with a placebo.

    The genetic and environmental contributions to the variation and longitudinal stability in childhood aggressive behavior were assessed in two large twin cohorts, the Netherlands Twin Register (NTR), and the Twins Early Development Study (TEDS; United Kingdom). In NTR, maternal ratings on aggression from the Child Behavior Checklist (CBCL) were available for 10,765 twin pairs at age 7, for 8,557 twin pairs at age 9/10, and for 7,176 twin pairs at age 12. In TEDS, parental ratings of conduct disorder from the Strength and Difficulty Questionnaire (SDQ) were available for 6,897 twin pairs at age 7, for 3,028 twin pairs at age 9 and for 5,716 twin pairs at age 12. In both studies, stability and heritability of aggressive behavioral problems was high. Heritability was on average somewhat, but significantly, lower in TEDS (around 60%) than in NTR (between 50% and 80%) and sex differences were slightly larger in the NTR sample. In both studies, the influence of shared environment was similar: in boys shared environment explained around 20% of the variation in aggression across all ages while in girls its influence was absent around age 7 and only came into play at later ages. Longitudinal genetic correlations were the main reason for stability of aggressive behavior. Individual differences in CBCL-Aggressive Behavior and SDQ-Conduct disorder throughout childhood are driven by a comparable but significantly different genetic architecture. © 2016 Wiley Periodicals, Inc.

    Purpose: Changes in F-18 fluorodeoxyglucose (FDG) uptake in normal tissues after chemoradiation therapy (CRT) potentially limit the ability of positron emission tomography (PET) to provide early assessment of therapeutic response. This study evaluated whether such changes negatively impact interpretation of posttherapy PET performed within 6 weeks of CRT completion and before definitive surgery in patients with locally advanced rectal cancer. The positive predictive value (PPV) and specificity of post-CRT PET, read clinically, was determined in 63 consecutive rectal cancer patients who had undergone preoperative CRT. Methods and Materials: A schema for identifying and scoring postradiation effects on PET was prospectively defined and applied in a blinded manner. This was compared with initial clinical reporting of response. Histologic assessment of the operative specimens was used as the reference standard. Correlation between clinical proctitis during CRT and radiation changes on subsequent PET was also assessed. Results: Clinical reporting of post-CRT PET yielded a high PPV (94%; 95% confidence interval, 89--100%) but may have been exaggerated by the low prevalence of complete tumor clearance (16%). The specificity was 80% with only two false-positive results. On blinded reading, significant post-CRT effects on PET were recorded in 4 of 63 patients (6% 95% confidence interval, 0-13%), but pattern recognition converted both false-positive PET results to a complete metabolic response. Clinical CRT proctitis was not correlated with PET findings. Conclusion: Postradiation effects do not appear to significantly compromise the interpretation of PET for therapeutic response assessment. The proposed PET pattern of response may further improve the specificity of PET.

    This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression. PMID:23440595

    2015-07-01

    Multiple sclerosis (MS) is a CNS disorder characterized by inflammation, demyelination and neurodegeneration, and is the most common cause of acquired nontraumatic neurological disability in young adults. The course of the disease varies between individuals: some patients accumulate minimal disability over their lives, whereas others experience a rapidly disabling disease course. This latter subset of patients, whose MS is marked by the rampant progression of disability over a short time period, is often referred to as having 'aggressive' MS. Treatment of patients with aggressive MS is challenging, and optimal strategies have yet to be defined. It is important to identify patients who are at risk of aggressive MS as early as possible and implement an effective treatment strategy. Early intervention might protect patients from irreversible damage and disability, and prevent the development of a secondary progressive course, which thus far lacks effective therapy.

    Rationale Preclinical experimental models of pathological aggressive behavior are a sorely understudied and difficult research area. Objectives How valid, reliable, productive and informative are the most frequently used animal models of excessive aggressive behavior? Methods The rationale, key methodological features, supporting data and arguments as well as their disadvantages and limitations of the most frequently used animal models for excessive aggressive behavior are summarized and their validity and reliability are evaluated. Results Excessive aggressive behavior is validly and reliably seen in (1) a proportion of feral-derived rats and selectively bred mice, (2) rats with compromised adrenal function resulting in a hypoglucocorticoid state, (3) a significant minority of mice, rats and monkeys after consumption of a moderate dose of alcohol, and (4) resident animals of various species after social instigation. Limitations of these procedures include restrictive animal research regulations, the requirement of expertise in surgical, pharmacological and behavioral techniques, and the behaviorally impoverished mouse strains that are used in molecular genetics research. Promising recent initiatives for novel experimental models include aggressive behaviors that are evoked by optogenetic stimulation and induced by the manipulation of early social experiences such as isolation rearing or social stress. Conclusions One of the most significant challenges for animal models of excessive, potentially abnormal aggressive behavior is the characterization of distinctive neurobiological mechanisms that differ from those governing species-typical aggressive behavior. Identifying novel targets for effective intervention requires increased understanding of the distinctive molecular, cellular and circuit mechanisms for each type of abnormal aggressive behavior.

  10. Attributional bias and reactive aggression.

    1996-01-01

    This article looks at a cognitive behavioral intervention designed to reduce minority youths' (Latino and African-American boys) levels of reactive peer-directed aggression. The BrainPower Program trains aggressive boys to recognize accidental causation in ambiguous interactions with peers. The objective of this research is to evaluate the effectiveness of this attribution retraining program in reducing levels of reactive, peer-directed aggression. This research hypothesizes that aggressive young boys' tendency to attribute hostile intentions to others in ambiguous social interactions causes display of inappropriate, peer-directed aggression. A reduction in attributional bias should produce a decrease in reactive physical and verbal aggression directed toward peers. A 12-session, attributional intervention has been designed to reduce aggressive students' tendency to infer hostile intentions in peers following ambiguous peer provocations. The program trains boys to (1) accurately perceive and categorize the available social cues in interactions with peers, (2) attribute negative outcomes of ambiguous causality to accidental or uncontrollable causes, and (3) generate behaviors appropriate to these retrained attributions. African-American and Latino male elementary-school students (N = 384), in grades four-six, served as subjects in one of three groups: experimental attribution retraining program, attention training, and no-attention control group. Three broad categories of outcome data were collected: teacher and administrator reports of behavior, independent observations of behavior, and self-reports from participating students. Process measures to assess implementation fidelity include videotaped training sessions, observations of intervention sessions, student attendance records, and weekly team meetings. The baseline data indicated that students who were evenly distributed across the four sites were not significantly different on the baseline indicators: student

    To report a rare case of severe fungal keratitis caused by Scedosporium apiospermum, which was treated with a penetrating tectonic keratoplasty and aggressive medical treatment. A 62-year-old woman with a history of soil contamination of the right eye while planting vegetables presented with a severe corneal abscess and ocular pain. The patient received medical treatment and underwent tectonic keratoplasty. Both corneal scrapings and the corneal button were evaluated microscopically. The samples were sent for aerobic and anaerobic bacterial and fungal cultures. Microbiological examinations showed S. apiospermum. The isolate was sensitive to amphoterycine B, caspofungin, voriconazole, and resistant to fluconazole. No clinical improvement was achieved with topical voriconazole, vancomycin, ceftazidime, and systemic voriconazole. A penetrating tectonic keratoplasty and lensectomy with continuation of anti-fungal therapy achieved satisfactory results. A fungal etiology should be suspected in a progressive and untreatable corneal abscess. Microbiological investigation is very important in early diagnosis. Despite early diagnosis and aggressive treatment, in selected cases removing the infected tissue surgically is vital in preserving the ocular globe and vision. PMID:23612853

    The indications of discography include situations in which there is inconsistency between the imaging and physical findings. Discography may also be performed prior to planned disc therapy such as percutaneous diskectomy or IDET. The diagnostic goal of the diskcogram is to reproduce the patient's original pain pattern by injection of the disc. If it is determined that the origin of the patient's back pain is diskcogenic, disc therapy can be provided by either surgical or non-surgical means. The non-surgical disc therapy includes steroid injections, IDET, or even percutaneous diskectomy. PMID:14651088

    2012-01-01

    The article describes the redirected, inter-specific aggression of a Maine Coon cat, which was principally directed towards the owners. The cat reacted towards different, nonspecific sounds with abrupt aggressive behaviour and injured the victims at this juncture with moderate scratching and biting. Exclusively using behaviour therapy did not achieve the desired result, thus the therapy was supported with pharmaceuticals. The cat orally received the selective serotonin re-uptake inhibitor fluvoxamine at an initial dosage of 0.5mg/kg BW once daily. After 4 weeks the application rate was increased to 1.0 mg/kg BW once daily. The medication did not cause any side effects. Together with the behaviour-modulating therapy, carried out parallel to the medication therapy, the aggressive behaviour problem of the cat was resolved. After administration for a period of 63 weeks the fluvoxamine therapy was discontinued by gradually reducing the dose without recurrence of the aggressive behaviour. PMID:23242225

    Osteoradionecrosis (ORN) of the skull is a rare but fatal complication of radiation therapy for the treatment of head and neck malignancies. The pathogenesis of ORN follows the "3Hs Theory" proposed by Marx (J Oral Maxillofac Surg 1983;41:283-288) in which radiation induces tissue injury by causing vessel thrombosis (hypovascularity), which leads to hypoxia, and results in cell death of the skin and the underlying structure of the bony element (hypocellularity) including the deep visceral structures. This note details a patient with severe and extensive ORN of the parietooccipital region of the skull because of a large dose of radiation therapy for the treatment of an invasive basal cell carcinoma of the scalp. The patient's condition was further complicated by an extensive infection with methicillin-resistant Staphylococcus aureus, which leads to meningitis and cerebral edema as well as cerebritis. The patient was successfully treated with interdisciplinary medical and surgical aggressive therapy and radical procedures involving 4 separate trips to the operating room for an 18-month period. Success was achieved because of early clinical diagnosis of ORN, aggressive eradication of infected and necrotic tissues including the brain, and restoration of functioning and viable tissues through the use of local flaps to change an open wound to a closed wound.

    Aggressive angiomyxoma (AA) is an uncommon mesenchymal tumor that is mostly derived from the female pelvic and perineal regions. AA is a locally infiltrative slow growing tumor with a marked tendency to local recurrence. Painless swelling located around the genitofemoral region is the common symptom; thus, it is often misdiagnosed as a gynecological malignancy or a groin hernia. A 35-year-old female patient who previously underwent surgery for left femoral hernia operation resulting in surgical failure was reoperated for a giant AA located in the pelvis. The tumor was completely excised with free margins. Histopathologic examination revealed an AA. The tumor size was measured as 24 × 12 × 6 cm with a weight of 4.2 kg. Immunohistochemically, the cells show positive staining with vimentin, desmin, estrogen, and progesterone receptor. S100, MUC4, CD34, and SMA were negative in the tumor cells. AA should be considered in the differential diagnosis of any painless swelling located in the genitofemoral region, particularly in women of reproductive age. The principle treatment should be complete surgical excision with tumor-free margins. Long-term follow-up and careful monitoring are essential due to its high tendency of local recurrence in spite of wide excision of the tumor. Adjuvant antihormonal therapy yields promising results for preventing recurrence. PMID:27274880

  18. Biomarkers of aggression in dementia.

    2016-08-01

    Dementia is a clinical syndrome defined by progressive global impairment of acquired cognitive abilities. It can be caused by a number of underlying conditions. The most common types of dementia are Alzheimer's disease (AD), frontotemporal dementia (FTD), vascular cognitive impairment (VCI) and dementia with Lewy bodies (DLB). Despite the fact that cognitive impairment is central to the dementia, noncognitive symptoms, most commonly described nowadays as neuropsychiatric symptoms (NPS) exist almost always at certain point of the illness. Aggression as one of the NPS represents danger both for patients and caregivers and the rate of aggression correlates with the loss of independence, cognitive decline and poor outcome. Therefore, biomarkers of aggression in dementia patients would be of a great importance. Studies have shown that different genetic factors, including monoamine signaling and processing, can be associated with various NPS including aggression. There have been significant and multiple neurotransmitter changes identified in the brains of patients with dementia and some of these changes have been involved in the etiology of NPS. Aggression specific changes have also been observed in neuropathological studies. The current consensus is that the best approach for development of such biomarkers may be incorporation of genetics (polymorphisms), neurobiology (neurotransmitters and neuropathology) and neuroimaging techniques.

    Aggression is ubiquitous in the animal kingdom, whenever the interests of individuals conflict. In contests between animals, the larger opponent is often victorious. However, counter intuitively, an individual that has little chance of winning (generally smaller individuals) sometimes initiates contests. A number of hypotheses have been put forward to explain this behaviour, including the ‘desperado effect’ according to which, the likely losers initiate aggression due to lack of alternative options. An alternative explanation suggested recently is that likely losers attack due to an error in perception: they mistakenly perceive their chances of winning as being greater than they are. We show that explaining the apparently maladaptive aggression initiated by the likely loser can be explained on purely economic grounds, without requiring either the desperado effect or perception errors. Using a game-theoretical model, we show that if smaller individuals can accurately assess their chance of winning, if this chance is less than, but close to, a half, and if resources are scarce (or the contested resource is of relatively low value), they are predicted to be as aggressive as their larger opponents. In addition, when resources are abundant, and small individuals have some chance of winning, they may be more aggressive than their larger opponents, as it may benefit larger individuals to avoid the costs of fighting and seek alternative uncontested resources.

    Despite the increasing prevalence of spinal infections, the subcategory of holospinal epidural abscesses (HEAs) is extremely infrequent and requires unique management. Panspinal imaging (preferably MRI), modern aggressive antibiotic therapy, and prompt surgical intervention remain the standard of care for all spinal axis infections including HEAs; however, the surgical decision making on timing and extent of the procedure still remain ill defined for HEAs. Decompression including skip laminectomies or laminoplasties is described, with varied clinical outcomes. In this review the authors present the illustrative cases of 2 patients with HEAs who were treated using skip laminectomies and epidural catheter irrigation techniques. The discussion highlights different management strategies including the role of conservative (nonsurgical) management in these lesions, especially with an already identified pathogen and the absence of mass effect on MRI or significant neurological defects. Among fewer than 25 case reports of HEA published in the past 25 years, the most important aspect in deciding a role for surgery is the neurological examination. Nearly 20% were treated successfully with medical therapy alone if neurologically intact. None of the reported cases had an associated cranial infection with HEA, because the dural adhesion around the foramen magnum prevented rostral spread of infection. Traditionally a posterior approach to the epidural space with irrigation is performed, unless an extensive focal ventral collection is causing cord compression. Surgical intervention for HEA should be an adjuvant treatment strategy for all acutely deteriorating patients, whereas aspiration of other infected sites like a psoas abscess can determine an infective pathogen, and appropriate antibiotic treatment may avoid surgical intervention in the neurologically intact patient.

    Perceivers are both accurate and biased in their understanding of others. Past research has distinguished between three types of accuracy: generalized accuracy, a perceiver’s accuracy about how a target interacts with others in general; perceiver accuracy, a perceiver’s view of others corresponding with how the perceiver is treated by others in general; and dyadic accuracy, a perceiver’s accuracy about a target when interacting with that target. Researchers have proposed that there should be more dyadic than other forms of accuracy among well-acquainted individuals because of the pragmatic utility of forecasting the behavior of interaction partners. We examined behavioral aggression among well-acquainted peers. A total of 116 9-year-old boys rated how aggressive their classmates were toward other classmates. Subsequently, 11 groups of 6 boys each interacted in play groups, during which observations of aggression were made. Analyses indicated strong generalized accuracy yet little dyadic and perceiver accuracy. PMID:17575243

    The surgical oncology remains an essential part in the multidisciplinary management for patients with cancer, even though the current progress in field of radiotherapy, chemotherapy, systemic therapies, including therapies directed to molecular targets. Their role impact in several moments during the management of an oncological patient: prevention, diagnosis, assessment of the spread of the disease, curative treatment, management of the sequels, complications by the treatment and not less important, the palliation. The current state of the surgical oncology as a result of a constant development, inspired by skillful hands with creative and restless minds, have achieved to mark the history of the medicine in an area which currently has a great transcendence and an accelerated growth in a short period of time. Under this argument, we have decided to present an updated overview about the role of the surgical oncology, from the evolution through the history until all their applications in the different areas of the oncology.

    Surgical intervention is mandatory in the case of documentation of the progression of glaucomatous optic neuropathy despite the administration of maximal tolerated medical therapy, and in cases where compliance is poor. Minimal complications, good long-term intraocular pressure (IOP) control, and precisely titrated target IOPs resulting in avoidance of visual impairment are the primary goals of surgical intervention. This article is an attempt to provide a broad overview of the therapeutic options available to the glaucoma surgeon. The available surgical modalities have undergone modifications and refinements over time, with a view to improve patient outcomes and visual recovery, yet are fraught with intra- and postoperative complications. The risk and benefits of each of the available surgical options must be critically evaluated and customized to fit the needs of the particular patient. There is insufficient evidence at present to establish the superiority of any of these surgeries over the other. PMID:21150024

    Background Low/ered cholesterol is linked to aggression in some study designs. Cases/series have reported reproducible aggression increases on statins, but statins also bear mechanisms that could reduce aggression. Usual statin effects on aggression have not been characterized. Methods 1016 adults (692 men, 324 postmenopausal women) underwent double-blind sex-stratified randomization to placebo, simvastatin 20mg, or pravastatin 40mg (6 months). The Overt-Aggression-Scale-Modified–Aggression-Subscale (OASMa) assessed behavioral aggression. A significant sex-statin interaction was deemed to dictate sex-stratified analysis. Exploratory analyses assessed the influence of baseline-aggression, testosterone-change (men), sleep and age. Results The sex-statin interaction was significant (P=0.008). In men, statins tended to decrease aggression, significantly so on pravastatin: difference=-1.0(SE=0.49)P=0.038. Three marked outliers (OASMa-change ≥40 points) offset otherwise strong significance-vs-placebo: statins:-1.3(SE=0.38)P=0.0007; simvastatin:-1.4(SE=0.43)P=0.0011; pravastatin:-1.2(SE=0.45)P=0.0083. Age≤40 predicted greater aggression-decline on statins: difference=-1.4(SE=0.64)P=0.026. Aggression-protection was emphasized in those with low baseline aggression: age<40-and-low-baseline-aggression (N=40) statin-difference-vs-placebo=-2.4(SE=0.71)P=0.0016. Statins (especially simvastatin) lowered testosterone, and increased sleep problems. Testosterone-drop on statins predicted aggression-decline: β=0.64(SE=0.30)P=0.034, particularly on simvastatin: β=1.29(SE=0.49)P=0.009. Sleep-worsening on statins significantly predicted aggression-increase: β=2.2(SE=0.55)P<0.001, particularly on simvastatin (potentially explaining two of the outliers): β=3.3(SE=0.83)P<0.001. Among (postmenopausal) women, a borderline aggression-increase on statins became significant with exclusion of one younger, surgically-menopausal woman (N=310) β=0.70(SE=0.34)P=0.039.

    Medical therapy with dopaminergic agonists (DAs) has been used for several decades for the treatment of both micro- and macroprolactinomas, without much differentiation between the two conditions. While most cases respond well to DAs in terms of prolactin normalization and control of tumor growth, DAs are often needed for many years, or even for lifetime. Concerns have been raised recently about the possible side effects of long-term use of these medications on the anatomy and function of the heart valves. While macroprolactinomas are rarely surgically curable, pituitary surgery in expert hands is a safe and effective method to permanently cure microprolactinomas, with long-term cure rates around 70 %. In this article, I will review the data on safety of DAs an on the effectiveness and safety of surgery, and I will make an argument that surgery should be offered as a possible therapy to microprolactinoma patients, provided that an experienced pituitary neurosurgeon is available.

    AIM To report the fungal organisms, clinical features, surgical treatment strategies, and outcomes of patients with culture-proven exogenous fungal endophthalmitis (EFE) secondary to keratitis, and evaluate the role of surgery in the treatment. METHODS The clinical records of 27 patients (27 eyes) with culture-proven EFE resulting from fungal keratitis treated at Shandong Eye Institute from January 2007 to January 2015 were retrospectively reviewed. Information about fungal culture results, clinical features, surgical procedures, and final visual acuity was obtained. RESULTS There were 39 positive culture results from samples of cornea, hypopyon, vitreous and lens capsule, accounting for 56%, 26%, 15% and 2.5%, respectively. Fusarium was identified in 44% (12/27) of the eyes, followed by Aspergillus in 22% (6/27). Posterior segment infection was involved in 78% (21/27) of the patients. The corneal infection was larger than 3 mm ×3 mm in 89% (24/27) of the patients, and 22% (6/27) of them had the entire cornea, and even the sclera involved. Three eyes had silicone oil tamponade, and two eyes had retinal detachment. Twenty-two eyes (81.5%) underwent penetrating keratoplasty (PKP), and over half of them (54.5%) were operated within 3d from the onset of antifungal therapy. Fourteen eyes (52%) underwent intracameral antifungal drug injection, and three of them required repeated injections. Fifteen eyes (55.6%) underwent pars plana vitrectomy (PPV). The rate of the eyes undergoing PPV as the initial surgical procedure was 60% (9/15), lower than 77% in PKP. Intravitreal injection was given in 59% of the eyes (16/27), and 75% of them required repeated injections. The final visual acuity was 20/100 or better in 37% of the eyes, and better than counting fingers in 55.6% of the eyes. Five eyes (18.5%) were eviscerated. In the two eyes with concurrent retinal detachment, one achieved retinal reattachment, and the other was eviscerated. In the three eyes with silicone oil

    Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are rare, and there is no report specifically dealing with patients of liver metastases from G3 GEP NETs.From January 2004 to January 2014, 36 conservative patients with G3 GEP NET liver metastases were retrospectively identified from 3 hepatobiliary centers in China. The clinical features and treatment outcomes were analyzed.Aggressive locoregional treatments (LT, including cytoreductive surgery, radiofrequency ablation, and liver-directed intra-arterial intervention) and systemic therapy (ST) were introduced separately or combined, with 26 (72%) patients receiving resection of primary tumor and/or hepatic metastases, 12 patients receiving non-surgical locoregional interventions (NSLRIs), and 22 patients receiving certain kind of STs. Median overall survival (OS) was 20.0 months (95% confidence interval [CI]: 8.9-31.1 months) and survival rates were 62.6%, 30.1%, and 19.8%, at 1, 3, and 5 years, respectively. The median OS was 9.0 months (95%CI: 3.3-14.7 months) for patients receiving only STs (n = 6), 19 months (95%CI: 1.3-36.8 months) for patients receiving LT followed by STs (n = 16), and 101 months (95%CI: 0.0-210.2 months) for patients receiving only LT (n = 12). Moreover, compared with those receiving only ST or best supportive care, patients given certain types of LTs had higher rates of symptom alleviation (3/8 versus 20/23). On univariate analysis, positive prognostic factors of survival were pancreatic primary tumor (P = 0.013), normal total bilirubin level (P = 0.035), receiving surgery (P = 0.034), receiving NSLRI (P = 0.014), and sum of diameters of remnant tumor < 5 cm (P = 0.008). On multivariate analyses, pancreatic primary tumor (P = 0.015), normal total bilirubin level (P = 0.002), and sum of diameters of remnant tumor < 5 cm (P = 0.001) remained to be independent prognostic factors.For patients with G3 GEP NET liver

    The authors report the case of a man who suffered from progressive, disseminated posttraumatic dural arteriovenous fistulas (DAVFs) resulting in death, despite aggressive endovascular, surgical, and radiosurgical treatment. This 31-year-old man was struck on the head while playing basketball. Two weeks later a soft, pulsatile mass developed at his vertex, and the man began to experience pulsatile tinnitus and progressive headaches. Magnetic resonance imaging and subsequent angiography revealed multiple AVFs in the scalp, calvaria, and dura, with drainage into the superior sagittal sinus. The patient was treated initially with transarterial embolization in five stages, followed by vertex craniotomy and surgical resection of the AVFs. However, multiple additional DAVFs developed over the bilateral convexities, the falx, and the tentorium. Subsequent treatment entailed 15 stages of transarterial embolization; seven stages of transvenous embolization, including complete occlusion of the sagittal sinus and partial occlusion of the straight sinus; three stages of stereotactic radiosurgery; and a second craniotomy with aggressive disconnection of the DAVFs. Unfortunately, the fistulas continued to progress, resulting in diffuse venous hypertension, multiple intracerebral hemorrhages in both hemispheres, and, ultimately, death nearly 5 years after the initial trauma. Endovascular, surgical, and radiosurgical treatments are successful in curing most patients with DAVFs. The failure of multimodal therapy and the fulminant progression and disseminated nature of this patient's disease are unique. PMID:11354419

    2015-09-01

    Transcatheter arterial chemoembolization (TACE) is performed worldwide for patients with intermediate-stage hepatocellular carcinoma (HCC). TACE has produced survival advantages in two randomized controlled trials and a meta-analysis, and is currently the mainstay of treatment for this stage of HCC. However, there are currently no global guidelines regarding the dose, choice or combination of cytotoxic agents for TACE; therefore, it is difficult to compare data from different TACE studies. In Japan, most of the TACE procedures have been based on iodized oil as conventional TACE, utilizing the microembolic and drug-carrying characteristic of iodized oil. Superselective TACE with lipiodol is the primary TACE procedure that has reported satisfactory levels of local control associated with a lower risk of complications. Conversely, TACE performed using drug-eluting beads has been widely used in western countries, and this has shown similar tumor response and median survival compared to conventional TACE. Moreover, the combination of TACE and molecular targeted agents is now ongoing to evaluate the synergistic effect. In this review, the indication, technical issues, and complications of TACE are reviewed. PMID:26675172

    Using the usual diagnostic tools like barium swallow examination, endoscopy, and manometry, we are able to diagnose a hiatal hernia, but it is not possible to predict the size of the hernia opening or, respectively, the size of the hiatal defect. At least a correlation can be expected if the gastroesophageal junction is endoscopically assessed in a retroflexed position, and graded according to Hill. So far, it is not possible to come to a clear conclusion how the hiatal closure during hiatal hernia repair should be performed. There is no consensus on using a mesh, and when using a mesh which type or shape should be used. Further studies including long-term results on this issue are necessary. However, it seems obvious to make the decision depending on certain conditions found during operation, and not on preoperative findings. PMID:24647816

    Surgical treatment of talus fractures can challenge even the most skilled foot and ankle surgeon. Complicated fracture patterns combined with joint dislocation of variable degrees require accurate assessment, sound understanding of principles of fracture care, and broad command of internal fixation techniques needed for successful surgical care. Elimination of unnecessary soft tissue dissection, a low threshold for surgical reduction, liberal use of malleolar osteotomy to expose body fracture, and detailed attention to fracture reduction and joint alignment are critical to the success of treatment. Even with the best surgical care complications are common and seem to correlate with injury severity and open injuries. PMID:19121756

    2002-04-01

    To investigate (1) the effects of exogenous testosterone (T) on self- and partner-reported aggression and mood and (2) the role of trait impulsivity in the T-aggression relationship. Thirty eugonadal men with partners were randomized into two treatment groups to receive: (1) 200 mg im T enanthate weekly for 8 weeks or (2) 200 mg im sodium chloride weekly for 8 weeks. Eight hypogonadal men received 200 mg im T enanthate biweekly for 8 weeks. All groups completed a battery of behavior measures at baseline (Week 0) and at Weeks 4 and 8. Cognitive and motor impulsivity were the only predictors of self-reported total aggression (over and above age and T levels) at Weeks 0, 4, and 8. No significant changes in aggression or mood levels were found in the eugonadal-treated group. Significant reductions in negative mood (tension, anger, and fatigue) followed by an increase in vigor were found in response to T treatment in the hypogonadal group. These results demonstrate that inability to control one's behavior when such control is required by a particular situation (impulsivity) was found to significantly predict levels of aggression over and above age and T level. These data do not support the hypothesis that supraphysiological levels of T (within this range) lead to an increase in self- and partner-reported aggression or mood disturbances. Instead, for the first time, this study has identified the high level of negative affect experienced by hypogonadal patients. These findings have implications for T replacement therapy and male contraception. PMID:12062320

    Fibromatosis are rare, accounting for 0.03% of all tumours. Mesenteric fibromatosis is a very rare (8% of all desmoid neoplasm). Aggressive fibromatosis of mesentery is a rare surgical problem affecting 2-4 per million people. Females are more commonly affected than males (Estrogen acts as a growth factor). It is locally invasive and tends to recur but never metastasize. Here, we are discussing about 24-year-old male presented with progressive abdomen distension associated with pain since one month. Abdominal examination showed a firm non-tender intra-abdominal mass, measuring around 15x14 cm size, with intrinsic mobility, which was perpendicular to mesenteric line, all borders were well-made out. CECT abdomen showed features suggestive of GIST . Elective Laparotomy was done and a giant mass arising from mesentery without any infiltration to the surrounding structures was noted. The entire mass was excised and mesentery repaired. Histopathology showed uniform band of spindle shaped cells arranged in fascicles admixed with blood vessels in a collagenous stroma. Immunohistochemistry showed Beta Catenin +ve, CD 117-ve, CD 34 –ve and SMA-ve, which is confirmative of Fibromatosis. Postoperative period was uneventful. PMID:25859491

    The current study explores associations between implicit and explicit aggression in young adult male prisoners, seeking to apply the Reflection-Impulsive Model and indicate parity with elements of the General Aggression Model and social cognition. Implicit cognitive aggressive processing is not an area that has been examined among prisoners. Two hundred and sixty two prisoners completed an implicit cognitive aggression measure (Puzzle Test) and explicit aggression measures, covering current behaviour (DIPC-R) and aggression disposition (AQ). It was predicted that dispositional aggression would be predicted by implicit cognitive aggression, and that implicit cognitive aggression would predict current engagement in aggressive behaviour. It was also predicted that more impulsive implicit cognitive processing would associate with aggressive behaviour whereas cognitively effortful implicit cognitive processing would not. Implicit aggressive cognitive processing was associated with increased dispositional aggression but not current reports of aggressive behaviour. Impulsive implicit cognitive processing of an aggressive nature predicted increased dispositional aggression whereas more cognitively effortful implicit cognitive aggression did not. The article concludes by outlining the importance of accounting for implicit cognitive processing among prisoners and the need to separate such processing into facets (i.e. impulsive vs. cognitively effortful). Implications for future research and practice in this novel area of study are indicated. PMID:25857854

    2016-08-01

    Malignant pleural mesothelioma (MPM) is associated with a poor prognosis. The main components of multimodality treatment include surgery, chemotherapy, and radiation therapy. Surgery remains controversial. Two procedures are currently offered: extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D). The recent scientific literature suggests that P/D is a well-tolerated procedure, with the potential of becoming a default procedure in multimodality regimens. However, the precise treatment schemes and surgical procedures are yet to be established. In our study, we review the advantages and disadvantages of EPP and P/D, summarize the post-EPP and post-P/D observations (including mortality, morbidity, and median survival time), and discuss the choice of surgical technique (EPP vs. P/D). Moreover, we highlight the aspects of the multimodality treatments that are offered to MPM patients, including chemotherapy, radiotherapy, intensity-modulated radiation therapy, and other types of therapy.

    Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease. PMID:27300457

    Chordomas are rare, locally aggressive skull base neoplasms known for local recurrence and not-infrequent treatment failure. Current evidence supports the role of maximal safe surgical resection. In addition to open skull-base approaches, the endoscopic endonasal approach to clival chordomas has been reported with favorable albeit early results. Adjuvant radiation is prescribed following complete resection, alternatively for gross residual disease or at the time of recurrence. The modalities of adjuvant radiation therapy reported vary widely and include proton-beam, carbon-ion, fractionated photon radiotherapy, and photon and gamma-knife radiosurgery. As of now, no direct comparison is available, and high-level evidence demonstrating superiority of one modality over another is lacking. While systemic therapies have yet to form part of any first-line therapy for chordomas, a number of targeted agents have been evaluated to date that inhibit specific molecules and their respective pathways known to be implicated in chordomas. These include EGFR (erlotinib, gefitinib, lapatinib), PDGFR (imatinib), mTOR (rapamycin), and VEGF (bevacizumab). This article provides an update of the current multimodality treatment of cranial base chordomas, with an emphasis on how current understanding of molecular pathogenesis provides a framework for the development of novel targeted approaches.

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

    2016-07-01

    The nasal cavity and sinuses may be exposed primarily via a dorsal or ventral surgical approach. Surgical planning involves the use of advanced imaging, such as computed tomography or MRI. Surgical treatment of lesions of the nasal cavity usually is limited to benign lesions or can also be used in combination with adjunctive therapy, such as radiation therapy. Extreme caution must be exercised with a dorsal approach to the nasal cavity to avoid complications of inadvertent penetration into the brain case. Gentle tissue handling and careful closure of the mucoperiosteum must be exercised following a ventral approach to minimize the risk of oronasal fistula formation. PMID:27217006

    2015-01-01

    Glioblastoma multiforme (GBM) is an aggressive and nearly uniformly fatal malignancy of the central nervous system. Despite extensive research and clinical trials over the past 50 years, very little progress has been made to significantly alter its lethal prognosis. The current standard of care (SOC) includes maximal surgical resection, radiation therapy and chemotherapy and temozolomide (TMZ), including the selective use of glucocorticoids for symptom control. These same treatments, however, have the potential to create an environment that may actually facilitate tumor growth and survival. Research investigating the unique metabolic needs of tumor cells has led to the proposal of a new metabolic treatment for various cancers including GBMs that may enhance the effectiveness of the SOC. The goal of metabolic cancer therapy is to restrict GBM cells of glucose, their main energy substrate. By recognizing the underlying energy production requirements of cancer cells, newly proposed metabolic therapy is being used as an adjunct to standard GBM therapies. This review will discuss the calorie restricted ketogenic diet (CR-KD) as a promising potential adjunctive metabolic therapy for patients with GBMs. The effectiveness of the CR-KD is based on the "Warburg Effect" of cancer metabolism and the microenvironment of GBM tumors. We will review recent case reports, clinical studies, review articles, and animal model research using the CR-KD and explain the principles of the Warburg Effect as it relates to CR-KD and GBMs. PMID:25949849

    Intracerebral haemorrhage (ICH) accounts for 15 to 20% of strokes. The condition carries a higher morbidity and mortality than occlusive stroke. Despite considerable research effort, no therapeutic modality either medical or surgical has emerged with clear evidence of benefit other than in rare aneurysmal cases. Intracerebral haemorrhages can be divided into those that arise from pre-existing macroscopic vascular lesions - so called "ictohaemorrhagic lesions", and those that do not; the latter being the commoner. Most of the research that has been done on the benefits of surgery has been in this latter group. Trial data available to date precludes a major benefit from surgical evacuation in a large proportion of cases however there are hypotheses of benefit still under investigation, specifically superficial lobar ICH treated by open surgical evacuation, deeper ICH treated with minimally invasive surgical techniques, and decompressive craniectomy. When an ICH arises from an ictohaemorrhagic lesion, therapy has two goals: to treat the effects of the acute haemorrhage and to prevent a recurrence. Three modalities are available for treating lesions to prevent recurrence: stereotactic radiosurgery, endovascular embolisation, and open surgical resection. As with ICH without an underlying lesion there is no evidence to support surgical removal of the haemorrhage in most cases. An important exception is ICHs arising from intracranial aneurysms where there is good evidence to support evacuation of the haematoma as well as repair of the aneurysm. PMID:17543995

    Background. The efficacy and tolerability of two different schedules of paclitaxel, carboplatin, and trastuzumab (PCarH) for HER2-positive, locally aggressive (stage IIB–IIIC) breast cancers were evaluated in this phase II trial. Methods. Patients were randomly assigned to receive either weekly (12 doses over 16 weeks) or once-every-3-weeks (4 doses over 12 weeks) treatment. The primary endpoint was pathologic complete remission (pCR) in the breast and axilla. To detect an assumed 35% pCR absolute difference between the two schedules, a minimum of 26 assessable patients in each group was required (two-sided α = 0.05, β = 0.2). Results. A total of 56 patients were enrolled (weekly group, n = 29; every-3-weeks group, n = 27). In the intent-to-treat analysis, pCR in the breast/axilla were found in 31 patients (55%; 95% confidence interval [CI]: 41%–69%). Compared with the every-3-weeks schedule, the weekly administration achieved higher pCR (41% vs. 69%; p = .03). After adjustment for clinical and pathological factors, the weekly administration was more effective than the every-3-weeks schedule, with hazard ratio of 0.3 (95% CI: 0.1–0.9; p = .03). Interestingly, weekly administration resulted in high pCR rates in both luminal-B (HER2-positive) and ERBB2+ tumors (67% vs. 71%; p = .78), whereas luminal-B (HER2-positive) tumors benefited less from the every-3-weeks schedule compared with the ERBB2+ tumors (21% vs. 62%, p = .03). These results remain after multivariate adjustment, showing weekly administration was more effective in the luminal-B (HER2-positive) subgroup (p = .02) but not in the ERBB2+ subgroup (p = .50). Conclusion. A more frequent administration might improve the possibility of eradicating invasive cancer in the breast and axilla, especially in the luminal-B (HER2-positive) subtype. Further studies to validate our findings are warranted. PMID:23635560

    PubMed

    Bisazza, Angelo; de Santi, Andrea

    2003-05-15

    Recent research has suggested that lateralization of aggressive behaviors could follow an homogeneous pattern among all vertebrates. A left eye/right hemisphere dominance in eliciting aggressive responses has been demonstrated for all groups of tetrapods but teleost fish for which data is lacking. Here we studied differential eye use during aggressive interactions in three species of teleosts: Gambusia holbrooki, Xenotoca eiseni and Betta splendens. In the first experiment we checked for lateralization in the use of the eyes while the subject was attacking its own mirror image. In order to confirm the results, other tests were performed on two species and eye preference was scored during attacks or displays directed toward a live rival. All three species showed a marked preference for using the right eye when attacking a mirror image or a live rival. Thus, the direction of asymmetry in fish appears the opposite to that shown by all the other groups of vertebrates. Hypotheses on the origin of the difference are discussed. PMID:12742249

  10. Neurobiology of Aggression and Violence

    PubMed Central

    Siever, Larry J.

    2014-01-01

    Acts of violence account for an estimated 1.43 million deaths worldwide annually. While violence can occur in many contexts, individual acts of aggression account for the majority of instances. In some individuals, repetitive acts of aggression are grounded in an underlying neurobiological susceptibility that is just beginning to be understood. The failure of “top-down” control systems in the prefrontal cortex to modulate aggressive acts that are triggered by anger provoking stimuli appears to play an important role. An imbalance between prefrontal regulatory influences and hyper-responsivity of the amygdala and other limbic regions involved in affective evaluation are implicated. Insufficient serotonergic facilitation of “top-down” control, excessive catecholaminergic stimulation, and subcortical imbalances of glutamatergic/ gabaminergic systems as well as pathology in neuropeptide systems involved in the regulation of affiliative behavior may contribute to abnormalities in this circuitry. Thus, pharmacological interventions such as mood stabilizers, which dampen limbic irritability, or selective serotonin reuptake inhibitors (SSRIs), which may enhance “top-down” control, as well as psychosocial interventions to develop alternative coping skills and reinforce reflective delays may be therapeutic.

    2014-12-01

    Structural equation modeling with latent variables was used to evaluate the direct and mediated effects of a neighborhood risk factor (negative teen behaviors) on the parent-report aggressive behavior of 213 students in grades 3 through 5 attending a school in a low-income, rural community. Contagion and social control hypotheses were examined as well as hypotheses about whether the neighborhood served as a microsystem or exosystem for rural pre-adolescents. Analyses took into account the clustering of students and ordinal nature of the data. Findings suggest that rural neighborhoods may operate as both a microsystem and exosystem for children, with direct contagion effects on their aggressive behaviors as well as indirect social control effects through parenting practices. Direct effects on aggression were also found for parenting practices and child reports of friends' negative behaviors. Pre-adolescence may be a transitional stage, when influences of the neighborhood on child behavior begin to compete with influences of caregivers. Findings can inform the timing and targets of violence prevention in rural communities. PMID:25205545

  12. Antisocial personality disorder, alcohol, and aggression.

    PubMed

    2001-01-01

    Epidemiologic studies and laboratory research consistently link alcohol use with aggression. Not all people, however, exhibit increased aggression under the influence of alcohol. Recent research suggests that people with antisocial personality disorder (ASPD) may be more prone to alcohol-related aggression than people without ASPD. As a group, people with ASPD have higher rates of alcohol dependence and more alcohol-related problems than people without ASPD. Likewise, in laboratory studies, people with ASPD show greater increases in aggressive behavior after consuming alcohol than people without ASPD. The association between ASPD and alcohol-related aggression may result from biological factors, such as ASPD-related impairments in the functions of certain brain chemicals (e.g., serotonin) or in the activities of higher reasoning, or "executive," brain regions. Alternatively, the association between ASPD and alcohol-related aggression may stem from some as yet undetermined factor(s) that increase the risk for aggression in general. PMID:11496966

    There is limited knowledge about the unique relations between adolescent reactive and proactive aggression and later psychosocial adjustment in early adulthood. Accordingly, this study prospectively examined associations between adolescent (mean age = 16) reactive and proactive aggression and psychopathic features, antisocial behavior, negative emotionality, and substance use measured 10 years later in early adulthood (mean age = 26). Study questions were examined in a longitudinal sample of 335 adolescent males. Path analyses indicate that after controlling for the stability of the outcome and the overlap between the two subtypes of aggression, reactive aggression is uniquely associated with negative emotionality, specifically anxiety, in adulthood. In contrast, proactive aggression is uniquely associated with measures of adult psychopathic features and antisocial behavior in adulthood. Both reactive and proactive aggression uniquely predicted substance use in adulthood, but the substances varied by subtype of aggression. Implications for findings are discussed. PMID:20589225

    In the treatment of violent-aggressive behavior, four major groups of drugs emerged: 1. Major tranquilizers in the treatment of aggressive-violent behavior associated with psychotic syndromes. 2. Anti-epileptic drugs such as diphenylhydantoin and barbiturates in the treatment of aggressive-violent behavior within the epileptic syndrome. 3. Psychostimulants in the treatment of aggressive behavior of adolescents and children within behavior disturbances. 4. Anti-male hormones such as cyproterone acetate in the treatment of violent-aggressive behavior associated with pathological sexual hyperactivity. Whereas each category of drug is predominantly effective in one type of aggressive syndrome, it may also be effective in other conditions as well. Aggression as a result of a personality disorder is most difficult to treat with drugs. PMID:34189

    Aggression after traumatic brain injury (TBI) is common but not well defined. Sixty-seven participants with first-time TBI were seen within three months of injury and evaluated for aggression. The prevalence of aggression was found to be 28.4% and to be predominantly verbal aggression. Post-TBI aggression was associated with new-onset major depression (p=0.02), poorer social functioning (p=0.04), and increased dependency on activities of daily living (p=0.03), but not with a history of substance abuse or adult/childhood behavioral problems. Implications of the study include early screening for aggression, evaluation for depression, and consideration of psychosocial support in aggressive patients. PMID:19996251

    Purpose The standard treatment for relapsed diffuse large B-cell lymphoma (DLBCL) is salvage chemotherapy followed by high-dose therapy and autologous stem-cell transplantation (ASCT). The impact of maintenance rituximab after ASCT is not known. Patients and Methods In total, 477 patients with CD20+ DLBCL who were in their first relapse or refractory to initial therapy were randomly assigned to one of two salvage regimens. After three cycles of salvage chemotherapy, the responding patients received high-dose chemotherapy followed by ASCT. Then, 242 patients were randomly assigned to either rituximab every 2 months for 1 year or observation. Results After ASCT, 122 patients received rituximab, and 120 patients were observed only. The median follow-up time was 44 months. The 4-year event-free survival (EFS) rates after ASCT were 52% and 53% for the rituximab and observation groups, respectively (P = .7). Treatment with rituximab was associated with a 15% attributable risk of serious adverse events after day 100, with more deaths (six deaths v three deaths in the observation arm). Several factors affected EFS after ASCT (P < .05), including relapsed disease within 12 months (EFS: 46% v 56% for relapsed disease after 12 months), secondary age-adjusted International Prognostic Index (saaIPI) more than 1 (EFS: 37% v 61% for saaIPI < 1), and prior treatment with rituximab (EFS: 47% v 59% for no prior rituximab). A significant difference in EFS between women (63%) and men (46%) was also observed in the rituximab group. In the Cox model for maintenance, the saaIPI was a significant prognostic factor (P < .001), as was male sex (P = .01). Conclusion In relapsed DLBCL, we observed no difference between the control group and the rituximab maintenance group and do not recommend rituximab after ASCT. PMID:23091101

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    Minimally invasive therapy (MIT) is one of the most important trends in modern medicine. It includes a wide range of therapies in videoscopic surgery and interventional radiology and is performed through small incisions. It reduces hospital stay-time by allowing faster recovery and offers substantially improved cost-effectiveness for the hospital and the society. However, the introduction of MIT has also led to new problems. The manipulation of structures within the body through small incisions reduces dexterity and tactile feedback. It requires a different approach than conventional surgical procedures, since eye-hand co-ordination is not based on direct vision, but more predominantly on image guidance via endoscopes or radiological imaging modalities. ARIS*ER is a multidisciplinary consortium developing a new generation of decision support tools for MIT by augmenting visual and sensorial feedback. We will present tools based on novel concepts in visualization, robotics and haptics providing tailored solutions for a range of clinical applications. Examples from radio-frequency ablation of liver-tumors, laparoscopic liver surgery and minimally invasive cardiac surgery will be presented. Demonstrators were developed with the aim to provide a seamless workflow for the clinical user conducting image-guided therapy.

    Immediate surgical implants provide a convenient means of replacing missing teeth without requiring hard tissue reduction of restoration-free potential fixed partial denture abutments. Although the procedure is described as "predictable," complications and failures do occur. This report presents four cases of immediate implant complications and their management, and discusses possible causes of the untoward results. Careful pre-operative planning, adequate surgical technique and post-surgical management, timely and suitable loading, and meticulous hygiene maintenance can serve to minimize implant complications and failures. The prospective immediate implant patient must be provided with sufficient information to allow informed consent to be given. Minimal requirements are a description of the procedures in terms the patient can understand, an explanation of potential risks and complications, and adequate disclosure of information about alternative therapies.

    Purpose: To evaluate mediastinal nodal clearance (MNC) rates after induction chemotherapy and concurrent, full-dose radiation therapy (RT) in a phase II trimodality trial (Radiation Therapy Oncology Group protocol 0229). Patients and Methods: Patients (n=57) with stage III non-small cell lung cancer (pathologically proven N2 or N3) were eligible. Induction chemotherapy consisted of weekly carboplatin (AUC = 2.0) and paclitaxel 50 mg/m{sup 2}. Concurrent RT was prescribed, with 50.4 Gy to the mediastinum and primary tumor and a boost of 10.8 Gy to all gross disease. The mediastinum was pathologically reassessed after completion of chemoradiation. The primary endpoint of the study was MNC, with secondary endpoints of 2-year overall survival and postoperative morbidity/mortality. Results: The grade 3/4 toxicities included hematologic 35%, gastrointestinal 14%, and pulmonary 23%. Forty-three patients (75%) were evaluable for the primary endpoint. Twenty-seven patients achieved the primary endpoint of MNC (63%). Thirty-seven patients underwent resection. There was a 14% incidence of grade 3 postoperative pulmonary complications and 1 30-day, postoperative grade 5 toxicity (3%). With a median follow-up of 24 months for all patients, the 2-year overall survival rate was 54%, and the 2-year progression-free survival rate was 33%. The 2-year overall survival rate was 75% for those who achieved nodal clearance, 52% for those with residual nodal disease, and 23% for those who were not evaluable for the primary endpoint (P=.0002). Conclusions: This multi-institutional trial confirms the ability of neoadjuvant concurrent chemoradiation with full-dose RT to sterilize known mediastinal nodal disease.

    Measuring the frequency of a defined outcome flaw for a series of patients undergoing operative procedures generates information for performance evaluation. Such data influence decisions to improve care if used responsibly. Wound infection (WI), bacterial invasion of the incision, is the most common infectious complication of surgical care and WI prevention has value because the complication affects economic, patient satisfaction, and patient functional status outcomes. WI frequency, one kind of surgical outcome flaw rate, is traditionally used to judge one aspect of surgical care quality. At the author's institution, global WI surveillance was conducted without interruption for 20 years. Results for 85,260 consecutive inpatient operations performed during the period showed that secular changes in infection rates occurred but were not necessarily caused by surgical care quality decrements.

    Throughout the clinical learning process, nursing students' perception of aggression might have implications in terms of their future professional behavior toward patients. Using a descriptive cross-sectional design, we investigated the relationships between student nurses' perceptions of aggression and their personal characteristics, defense styles, and a convenience sample of 1539 experiences of aggressive behavior in clinical practice. Information about the students' personal features, their clinical practice, and experiences of aggressive behavior was obtained by questionnaire. The Turkish version of the Perception of Aggression Scale and Defense Styles Questionnaire-40 were also used. Students were frequently exposed to verbal aggression from patients and their relatives. And perceived patient aggression negatively, perception of aggression were associated with sex, defense styles, feelings of safety, and experiences of aggressions during clinical practice. Of interest is the reality that student nurses should be prepared for untoward events during their training. PMID:26916604

    2013-01-01

    Glioblastoma (GBM) is the most common and most aggressive primary brain malignancy and, as it stands, is virtually incurable. With the current standard of care, maximum feasible surgical resection followed by radical radiotherapy and adjuvant temozolomide, survival rates are at a median of 14.6 months from diagnosis in molecularly unselected patients (1). Collectively, the current knowledge suggests that the continued tumor growth and survival is in part due to failure to mount an effective immune response. While this tolerance is subtended by the tumor being utterly “self,” it is to a great extent due to local and systemic immune compromise mediated by the tumor. Different cell modalities including lymphokine-activated killer cells, natural killer cells, cytotoxic T lymphocytes, and transgenic chimeric antigen receptor or αβ T cell receptor grafted T cells are being explored to recover and or redirect the specificity of the cellular arm of the immune system toward the tumor complex. Promising phase I/II trials of such modalities have shown early indications of potential efficacy while maintaining a favorable toxicity profile. Efficacy will need to be formally tested in phase II/III clinical trials. Given the high morbidity and mortality of GBM, it is imperative to further investigate and possibly integrate such novel cell-based therapies into the current standards-of-care and herein we collectively assess and critique the state-of-the-knowledge pertaining to these efforts.

    OBJECTIVE: To determine the morbidity and mortality of pancreaticoduodenectomy followed by electron-beam intraoperative radiation therapy (EB-IORT). SUMMARY BACKGROUND DATA: Local recurrence following pancreaticoduodenectomy occurs in 50% to 90% of patients who undergo a potentially curative surgical resection for adenocarcinoma of the pancreatic head. To improve local disease control, a more aggressive retroperitoneal dissection has been combined with adjuvant EB-IORT. METHODS: Forty-one patients with malignant neoplasms of the periampullary region underwent pancreaticoduodenectomy followed by EB-IORT between January 1989 and May 1992. EB-IORT was delivered in a dedicated operative suite, eliminating the need for patient relocation. Electron-beam energies of 6 to 12 MeV were used to deliver 10 to 20 Gy to the treatment field following resection but before pancreatic, biliary, and gastrointestinal reconstruction. RESULTS: Median operative time was 9 hours, blood loss was 1 L, perioperative transfusion requirement was 2 units, and hospital stay was 20 days. One patient died of a postoperative myocardial infarction, and four patients required reoperation, one for an anastomotic leak. No patient failed to receive EB-IORT because of operative complications during the time period of this study. CONCLUSION: Adjuvant EB-IORT after pancreaticoduodenectomy can be delivered safely, with low mortality and acceptable morbidity. Images Figure 1. Figure 1. PMID:8101073

  11. Psychopharmacological treatment of aggression in schizophrenic patients.

    Aggressive behavior is frequently observed in schizophrenic patients. More than 50 % of all psychiatric patients and 10 % of schizophrenic patients show aggressive symptoms varying from threatening behavior and agitation to assault. The pharmacological treatment of acute, persisting and repetitive aggression is a serious problem for other patients and staff members. Not only is violent behavior from mentally ill patients the most detrimental factor in their stigmatization, aggression is also a considerable direct source of danger for the patients themselves. Based on rather limited evidence, a wide variety of medications for the pharmacological treatment of aggression has been recommended: typical and atypical antipsychotics, benzodiazepines, mood stabilizers, beta-blockers and selective serotonin reuptake inhibitors (SSRIs). Most clinical information on treating aggression has been collected for atypical neuroleptics, particularly for clozapine. Several retrospective and open studies indicate its efficacy. Treatment duration of 6 months is recommended to induce a stable reduction of physical and verbal aggression. Severe side effects have very rarely been seen. At the moment, clozapine seems to be the first choice in aggression treatment. Within the last few years, about 10 articles were published showing that this is the most effective antiaggressive agent in the treatment of aggression and agitation in psychiatric patients, independent of psychiatric diagnosis. However, clozapine, like all the other substances used, does not have an established indication for the treatment of aggressive symptoms. Noncompliance with medication makes it difficult to choose the right preparation for the medication: tablets, liquids, intramuscular injections and readily soluble "FDDFs" are available. Ethical, juridical and methodological problems prevent controlled studies from establishing a reference in the treatment of aggression in mentally ill patients. This review summarizes

    Fourteen patients with aspergilloma (fungus ball) were reviewed. Hemoptysis was the major symptom (93%). Chest roentgenograms disclosed a "fungus ball" in every patient, and the mycelia of Aspergillus fumigatus were recovered from all resected specimens. One of three patients treated by pneumonectomy died post-operatively. A lobectomy was performed in ten patients, and segmental resection in one without mortality or significant morbidity. There has been no evidence of recurrence in a follow up of six months to ten years. On the basis of this experience and a review of the literature, excision of a solitary "fungus ball" is recommended when the diagnosis is made. Non-surgical therapy should be reserved for patients whose general medical status or pulmonary reserved prohibit resection. Images Fig. 1. Fig. 2a. Fig. 2b. Fig. 3. Fig. 4. PMID:327952

  13. Surgical implications of tumour immunology.

    PubMed Central

    1996-01-01

    The presence of immune infiltration of tumour deposits and the existence of effective in vitro anti-tumour immune responses would suggest the possibility of therapeutic manipulation against tumour cells. However, clinical immunotherapy has shown little promise as a cancer treatment. Numerous explanations for this inefficacy have been proposed, one of which involves the elaboration of immunosuppressive moieties from tumour cells. The results of studies presented below show that serum from patients with gastrointestinal and other tumours have immunosuppressive influences on normal lymphocytes. The degree of this in vitro inhibition is related to tumour 'bulk' and may reflect a systemic immunosuppressive influence of the tumour. Isolation and culture of lymphocytes from gastrointestinal tumour deposits demonstrated that these immune cells are functionally inert, suggesting the existence of an immunosuppressive tumour microenvironment. The isolation and partial purification of an immunosuppressive moiety from conditioned culture medium of a variety of human tumour cell lines further supports the hypothesis of tumour-mediated immunosuppression. A number of protein tumour cell products have been described with potent immunosuppressive properties. These include transforming growth factor-beta, interleukin-10, and the retroviral envelope protein p15E. The surgical implications of the proposed tumour-host immune relationship includes the hypothesis that clinically apparent disease may not be amenable to immune attack owing to tumour-mediated immune suppression. The use of immunostimulatory strategies as adjuvant perioperative therapy would seem a more effective environment for the activation of antitumour immune responses in the surgical patient.

    There are limited options to patients with gastroesophageal reflux disease (GERD) who are not satisfied with acid suppression therapy. Fundoplication, the standard surgical procedure for GERD, is effective but is associated with adverse side effects and has thus been performed less frequently, creating a need for alternative surgical interventions that are effective, yet less invasive and reversible. Lately, two such interventions were developed: the magnetic sphincter augmentation and electrical stimulation of the lower esophageal sphincter. Human studies describing safety and efficacy over a follow-up period of a number of years have been published, documenting efficacy and safety of these interventions. Future studies should clarify the role of these procedures in the spectrum of GERD therapy. PMID:25947638

    Passive-aggressive organizations are friendly places to work: People are congenial, conflict is rare, and consensus is easy to reach. But, at the end of the day, even the best proposals fail to gain traction, and a company can go nowhere so imperturbably that it's easy to pretend everything is fine. Such companies are not necessarily saddled with mulishly passive-aggressive employees. Rather, they are filled with mostly well-intentioned people who are the victirms of flawed processes and policies. Commonly, a growing company's halfhearted or poorly thought-out attempts to decentralize give rise to multiple layers of managers, whose authority for making decisions becomes increasingly unclear. Some managers, as a result, hang back, while others won't own up to the calls they've made, inviting colleagues to second-guess or overturn the decisions. In such organizations, information does not circulate freely, and that makes it difficult for workers to understand the impact of their actions on company performance and for managers to correctly appraise employees' value to the organization. A failure to accurately match incentives to performance stifles initiative, and people do just enough to get by. Breaking free from this pattern is hard; a long history of seeing corporate initiatives ignored and then fade away tends to make people cynical. Often it's best to bring in an outsider to signal that this time things will be different. He or she will need to address every obstacle all at once: clarify decision rights; see to it that decisions stick; and reward people for sharing information and adding value, not for successfully negotiating corporate politics. If those steps are not taken, it's only a matter of time before the diseased elements of a passive-aggressive organization overwhelm the remaining healthy ones and drive the company into financial distress.

    From December 1981 to December 1989, 20 patients with primary or recurrent retroperitoneal sarcoma received 4000 to 5000 cGy of external beam radiation therapy (EBRT) in conjunction with surgical resection and intraoperative radiation therapy (IORT). Seventeen of 20 patients underwent complete (14 patients) or partial (3 patients) resection. Three patients had shown evidence of metastases after EBRT by the time of surgery. The 4-year actuarial local control and disease-free survival rates of the 17 patients undergoing resection were 81% and 64%, respectively. Twelve patients received IORT at the time of resection for microscopic disease (10 patients) or gross residual sarcoma (2 patients). Of the ten patients receiving IORT for microscopic tumor, one patient has died of local failure and peritoneal sarcomatosis and two patients have died of distant metastases only. The remaining seven patients are disease-free. One patient treated for gross residual sarcoma has experienced a local failure 1 year after IORT and is without disease 7 years after salvage chemotherapy. The other patient treated for gross residual sarcoma has died of local failure. Five patients did not receive IORT at the time of resection because of the extensive size of the tumor bed. Three of these patients are disease-free with one patient alive with lung metastases and one patient dying of hepatic metastases. Aggressive radiation and surgical procedures appear to provide satisfactory resectability and local control with acceptable tolerance. PMID:1906369

    The selection of correct treatment for lung cancer is multidisciplinary collaboration and requires careful assessment of the extent of the tumor and the condition of the patient. In localized non-small cell lung cancer, mere surgery or surgery in combination with adjuvant therapies are the best options for curing the disease. The trend in modern surgery is mini-invasiveness and preservation of lung tissue. Accordingly, any unit conducting lung cancer operations should have access to all modern techniques in order to provide each patient with optimal, patient-tailored surgical therapy. PMID:27132298

    Laboratory research has produced detailed descriptions of aggression and defense patterns in the rat, mouse, and hamster, showing strong similarities, but also some differences, across these species. Research on target sites for attack, in conjunction with analyses of the situational antecedents of attack behaviors and of responsivity of these to conditions that elicit fear, has also provided a strong basis for analysis of offensive and defensive aggression strategies and for identification of combinations of these modalities such as may occur in maternal aggression. These patterns have been empirically differentiated from phenomena such as play fighting or predation and compared for laboratory rodents and their wild ancestors. An array of tasks, suitable for use with pharmacological and experimental manipulations, is available for analysis of both aggression and defense. These developments should produce a firm basis for research using animal models to analyze a broad array of aggression-related phenomena, including systematic approaches to understanding the normal antecedents and consequences of each of several differentiable types of aggressive behavior. Despite this strong empirical and analytic background, laboratory animal aggression research has been in a period of decline, spanning several decades, relative to comparable research focusing on areas such as sexual behavior or stress. Problems that may have contributed to the relative neglect of aggression research include confusion about the interpretation of different tasks for eliciting aggression; difficulties and labor intensiveness of observational measures needed for an adequate differentiation of offensive and defensive behaviors; analytic difficulties stemming from the sensitivity of offensive aggression to the inhibitory effects of fear or defensiveness; lack of a clear relationship between categories of aggressive behavior as defined in animal studies and those used in human aggression research; and

    Purpose of review Despite the application of prophylactic antimicrobial therapy and advanced technologies, infection remains one of the most common causes of morbidity and mortality in surgical patients. Understanding the pathogenesis of surgical infection would offer new insights into the development of biomarkers to predict and stratify infection in patients, and to explore specific strategies to minimize this serious postoperative complication. Recent findings The acute nonspecific inflammatory response triggered by endogenous danger signals evoked by surgical insult is beneficial, while paradoxically associated with reduced resistance to infection. There is growing evidence indicating that primed inflammation by surgical insult exaggerates the dysregulation of the immune-inflammatory response to the invasion of pathogens postoperatively. Innate immune receptors, such as Toll-like receptors (TLRs), contribute to detecting both pathogen-associated molecular patterns and endogenous damage-associated molecular patterns, and to further amplifying inflammatory responses to infection. Current evidence shows the fascinating role of non-TLRs in the process of infection. Non-TLRs, such as membrane-associated triggering receptor expressed on myeloid cells family, cytosolic nucleotide-binding oligomerization domain-like receptors and nuclear receptor nuclear family 4 subgroup A receptors, are also crucial in triggering the immune responses and mounting an effective defense against surgical insults and the second hit of infection. Summary Understanding the pivotal role of non-TLRs in sensing exogenous and endogenous molecules, and the influence of primed systemic inflammation and depressed immune status on the defense against pathogen after surgical insult, would be helpful to fully explore the relevant sophisticated phenomena of surgical infection, and to elucidate the occurrence of heterogeneous constellations of clinical signs and symptoms among this special population

    The results of radiation therapy in the management of 27 patients with malignant mesothelioma were reviewed. Eight patients were treated with a curative intent combining attempted surgical excision of tumor (thoracic in 6 and peritoneal in 2), aggressive radiation therapy, and combination chemotherapy using an adriamycin-containing regimen. One patient achieved a 2-year disease-free inteval followed by recurrence of tumor above the thoracic irradiation field. This patient was retreated with localized irradiation and is disease-free after 5 years of initial diagnosis. One patient has persistent abdominal disease at 18 months; the other 6 patients suffered local recurrence within 8-13 months of initiation of treatment. Radiation therapy was used in 19 other patients who received 29 courses for palliation of dyspnea, superior vena cava syndrome, dysphagia, or neurological symptoms of brain metastasis. A palliation index was used to determine the effectiveness of irradiation and revealed that relief of symptoms was complete or substantial in 5 treatment courses, moderately effective in 6 courses and inadequate in 18 treatment courses. Adequate palliation strongly correlated with a dose at or above 4,000 rad in 4 weeks. The management of patients with mesothelioma requires new and innovative approaches to increase the effectiveness of radiation therapy and minimize the significant potential combined toxicity of pulmonary irradiation and adriamycin.

    Pancreatic cancer patients presenting with borderline resectable or locally advanced unresectable tumors remain a therapeutic challenge. Despite the lack of high quality randomized controlled trials, perioperative neoadjuvant treatment strategies are often employed for this group of patients. At present the FOLFIRINOX regimen, which was established in the palliative setting, is the backbone of neoadjuvant therapy, whereas local ablative treatment, such as stereotactic irradiation and irreversible electroporation are currently under investigation. Resection after modern multimodal neoadjuvant therapy follows the same principles and guidelines as upfront surgery specifically regarding the extent of resection, e.g. lymphadenectomy, vascular resection and multivisceral resection. Because it is still exceedingly difficult to predict tumor response after neoadjuvant therapy, a special treatment approach is necessary. In the case of localized stable disease following neoadjuvant therapy, aggressive surgical exploration with serial frozen sections at critical (vascular) margins might be necessary to minimize the risk of debulking procedures and maximize the chance of a curative resection. A multidisciplinary and individualized approach is mandatory in this challenging group of patients. PMID:27138271

    Sleep disturbances negatively impact numerous functions and have been linked to aggression and violence. However, a clear effect of sleep deprivation on aggressive behaviors remains unclear. We find that acute sleep deprivation profoundly suppresses aggressive behaviors in the fruit fly, while other social behaviors are unaffected. This suppression is recovered following post-deprivation sleep rebound, and occurs regardless of the approach to achieve sleep loss. Genetic and pharmacologic approaches suggest octopamine signaling transmits changes in aggression upon sleep deprivation, and reduced aggression places sleep-deprived flies at a competitive disadvantage for obtaining a reproductive partner. These findings demonstrate an interaction between two phylogenetically conserved behaviors, and suggest that previous sleep experiences strongly modulate aggression with consequences for reproductive fitness.

    Recent evidence indicates that a sexually dimorphic feature of humans, the facial width-to-height ratio (FWHR), is positively correlated with reactive aggression, particularly in men. Also, predictions about the aggressive tendencies of others faithfully map onto FWHR in the absence of explicit awareness of this metric. Here, we provide the first evidence that amygdala reactivity to social signals of interpersonal challenge may underlie the link between aggression and the FWHR. Specifically, amygdala reactivity to angry faces was positively correlated with aggression, but only among men with relatively large FWHRs. The patterns of association were specific to angry facial expressions and unique to men. These links may reflect the common influence of pubertal testosterone on craniofacial growth and development of neural circuitry underlying aggression. Amygdala reactivity may also represent a plausible pathway through which FWHR may have evolved to represent an honest indicator of conspecific threat, namely by reflecting the responsiveness of neural circuitry mediating aggressive behavior.

    Rhabdomyosarcoma (RMS) are soft-tissue sarcoma commonly encountered in childhood. RMS cells can acquire invasive behavior and form metastases. The metastatic dissemination implicates many proteases among which are mu-calpain and m-calpain. Study of calpain expression and activity underline the deregulation of calpain activity in RMS. Analysis of kinetic characteristics of RMS cells, compared to human myoblasts LHCN-M2 cells, shows an important migration velocity in RMS cells. One of the major results of this study is the positive linear correlation between calpain activity and migration velocity presenting calpains as a marker of tumor aggressiveness. The RMS cytoskeleton is disorganized. Specifying the role of mu- and m-calpain using antisense oligonucleotides led to show that both calpains up-regulate alpha- and beta-actin in ARMS cells. Moreover, the invasive behavior of these cells is higher than that of LHCN-M2 cells. However, it is similar to that of non-treated LHCN-M2 cells, when calpains are inhibited. In summary, calpains may be involved in the anarchic adhesion, migration and invasion of RMS. The direct relationship between calpain activity and migration velocities or invasive behavior indicates that calpains could be considered as markers of tumor aggressiveness and as potential targets for limiting development of RMS tumor as well as their metastatic behavior.

    Non-melanoma skin cancer (NMSC) is the most common form of cancer in the Caucasian population. Among NMSC types, basal cell carcinoma (BCC) has the highest incidence and squamous cell carcinoma (SCC) is less common although it can metastasize, accounting for the majority of NMSC-related deaths. Treatment options for NMSC include both surgical and non-surgical modalities. Even though surgical approaches are most commonly used to treat these lesions, Photodynamic Therapy (PDT) has the advantage of being a non-invasive option, and capable of field treatment, providing optimum cosmetic outcomes. Numerous clinical research studies have shown the efficacy of PDT for treating pre-malignant and malignant NMSC. However, resistant or recurrent tumors appear and sometimes become more aggressive. In this sense, the enhancement of PDT effectiveness by combining it with other therapeutic modalities has become an interesting field in NMSC research. Depending on the characteristics and the type of tumor, PDT can be applied in combination with immunomodulatory (Imiquimod) and chemotherapeutic (5-fluorouracil, methotrexate, diclofenac, or ingenol mebutate) agents, inhibitors of some molecules implicated in the carcinogenic process (COX2 or MAPK), surgical techniques, or even radiotherapy. These new strategies open the way to a wider improvement of the prevention and eradication of skin cancer. PMID:26516853

    Like most animal species, fruit flies fight to obtain and defend resources essential to survival and reproduction. Aggressive behavior in Drosophila is genetically specified and also strongly influenced by the fly's social context, past experiences and internal states, making it an excellent framework for investigating the neural mechanisms that regulate complex social behaviors. Here, I summarize our current knowledge of the neural control of aggression in Drosophila and discuss recent advances in understanding the sensory pathways that influence the decision to fight or court, the neuromodulatory control of aggression, the neural basis by which internal states can influence both fighting and courtship, and how social experience modifies aggressive behavior.

    Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

Nineteen percent of institutions (17 institutions) reported observing aggression, and 6 of these institutions recorded multiple instances of aggression, though a vast majority of these cases resulted in mild injuries or none at all. The female was the primary aggressor in 23% of cases, the male was the primary aggressor in 58% of cases, and both were the primary aggressor in 1 case. Although these aggressive interactions were often not associated with a known cause, 27% of cases were associated with food displacement. In most cases, management changes, including trying new pairings, greatly reduced situational aggression, suggesting that individual personalities may play a factor in aggression. These data begin to explain the extent of aggression observed in captive gibbons; future studies will address possible correlations with aggression and introduction techniques. PMID:26963568

    Using conservation of resources theory, we examined the relationship between intimate partner aggression enacted against heterosexual women and 3 types of work-related outcomes for these women: withdrawal while at work (i.e., cognitive distraction, work neglect), withdrawal from work (i.e., partial absenteeism, intentions to quit), and performance. In Study 1, we compared withdrawal both at and from work across 3 clinically categorized groups of women (n = 50), showing that experiencing physical aggression is related to higher work neglect. We replicated and extended these findings in Study 2 using a community sample of employed women (n = 249) by considering the incremental variance explained by both physical aggression and psychological aggression on these same outcomes. Results showed that physical aggression predicted higher levels of withdrawal both at and from work, with psychological aggression predicting additional variance in partial absenteeism over and above the effects of physical aggression. Study 3 extended the model to include academic performance as an outcome in a sample of female college students (n = 122) in dating relationships. Controlling for the women's conscientiousness, psychological aggression predicted lower academic performance after accounting for the effects of physical aggression. We discuss theoretical and practical implications of these results, as well as directions for future research. PMID:25068818

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    Hyperglycemia frequently occurs with acute medical illness, especially among patients with cardiovascular disease, and has been linked to increased morbidity and mortality in critically ill patients. Even patients who are normoglycemic can develop hyperglycemia in response to acute metabolic stress. An expanding body of literature describes the benefits of normalizing hyperglycemia with insulin therapy in hospitalized patients. As a result, both the American Diabetes Association and the American College of Endocrinology have developed guidelines for optimal control of hyperglycemia, specifically targeting critically ill, hospitalized patients. Conventional blood glucose values of 140–180 mg/dL are considered desirable and safely achievable in most patients. More aggressive control to <110 mg/dL remains controversial, but has shown benefits in certain patients, such as those in surgical intensive care. Intravenous infusion is often used for initial insulin administration, which can then be transitioned to subcutaneous insulin therapy in those patients who require continued insulin maintenance. This article reviews the data establishing the link between hyperglycemia and its risks of morbidity and mortality, and describes strategies that have proven effective in maintaining glycemic control in high-risk hospitalized patients.

    Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing relational aggression on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of different questionnaires involving media and aggression at 3 different time points. Results revealed that viewing relational aggression on TV was longitudinally associated with future relational aggression. However, early levels of relational aggression did not predict future exposure to televised relational aggression. Conversely, there was a bidirectional relationship between TV violence and physical aggression over time. No longitudinal evidence was found for a general effect of viewing TV, as all significant media effects were specific to the type of aggression viewed. These results support the general aggression model and suggest that viewing relational aggression in the media can have a long-term effect on aggressive behavior during adolescence. PMID:26595354

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Anger is an empirically established precipitant to aggressive responding toward intimate partners. The current investigation examined the effects of anger, as experienced by both partners, as well as gender and previous aggression, on in vivo intimate partner aggression using a prospective daily diary methodology. Participants (N = 118 couples) individually provided 56 consecutive, daily reports of affective experience and partner aggression. Multilevel models were estimated using the Actor Partner Interdependence Model framework to analyze the daily associations between anger and partner aggression perpetration among male and female participants as moderated by aggression history. Results revealed that both Actor and Partner anger were generally associated with subsequently reported daily conflict. Further, increases in daily Partner anger were associated with corresponding increases in partner aggression among females who reported high anger and males, regardless of their own anger experience. Increases in Actor anger were associated with increases in daily partner aggression only among previously aggressive females. Previously aggressive males and females consistently reported greater perpetration than their nonaggressive counterparts on days of high Actor anger experience. Results emphasize the importance of both Actor and Partner factors in partner aggression and suggest that female anger may be a stronger predictor of both female-to-male and male-to-female partner aggression than male anger, when measured at the daily level.

    Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women. PMID:21046605

    This study extends the use of the Impulsive/Premeditated Aggression Scale for subtyping aggressive behavior among adolescents with Conduct Disorder. Of the Conduct Disorder symptoms, aggression has the strongest prognostic and treatment implications. While aggression is a complex construct, convergent evidence supports a dichotomy of impulsive and premeditated aggressive subtypes that are qualitatively different from one another in terms of phenomenology and neurobiology. Previous attempts at measuring subtypes of aggression in children and adults are not clearly generalizable to adolescents. Sixty-six adolescents completed a questionnaire for characterizing aggression (Impulsive/Premeditated Aggression Scale), along with standard measures of personality and general functioning. Principal components analysis demonstrated two stable factors of aggression with good internal consistency and construct validity. Compared to the premeditated aggression factor, the impulsive aggression factor was associated with a broader range of personality, thought, emotional, and social problems. As in the adult and child literature, characterization of aggressive behavior into two subtypes appears to be relevant to understanding individual differences among adolescents with Conduct Disorder.

    Fragility fractures typically occur in elderly patients related principally to osteoporosis. A significative percentage of these fractures have to be treated surgically but comorbilities are often present, and need to be grossly stabilized before surgery. However, there is for these fractures a high rate of morbidity and mortality at short-term. Moreover, patients affected by a fragility fracture are at risk for another fragility fracture later in life. The Authors present an overview of the main patterns of proximal femoral fractures, underlining the peculiar features and choices of surgical treatment, and relating to specific indications and results of each treatment.

    Pulmonary cystic echinococcosis is a very rare disease in Germany. It is caused by the larvae of the dog tapeworm (echinococcus granulosus). The liver is the most affected organ, followed by the lungs. Surgery remains the main therapeutic approach for pulmonary CE. Whenever possible, parenchyma-preserving lung surgery should be preferred over anatomic lung resections. To ensure best therapeutic results, surgery needs to be performed under precise consideration of important infectiological aspects and patients should be treated in specialised centres based on interdisciplinary consensus. In addition to surgical aspects, this review summarises special infectiological features of this disease, which are crucial to the surgical approach. PMID:26351761

    This paper considers two new elevator and dental forceps techniques for the atraumatic removal of teeth to avoid a surgical procedure where possible. The techniques described should be applicable in relatively well defined but commonly occurring situations. The two techniques involve the unconventional use of conventional dental extraction forceps, with the aim of facilitating removal of the retained roots of certain teeth: the first for incisors, canines and premolars and the second for lower first molars. The term 'surgical forceps technique's is tentatively put forward as a description of these hybrid procedures. PMID:11819949

    Background Aggression is a major public health issue and is integral to several mental health disorders. Antiepileptic drugs may reduce aggression by acting on the central nervous system to reduce neuronal hyper-excitability associated with aggression. Objectives To evaluate the efficacy of antiepileptic drugs in reducing aggression and associated impulsivity. Search methods We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, metaRegister of Controlled Trials (mRCT) and ClinicalTrials.gov to April 2009. We also searched Cochrane Schizophrenia Group’s register of trials on aggression, National Research Record and handsearched for studies. Selection criteria Prospective, placebo-controlled trials of antiepileptic drugs taken regularly by individuals with recurrent aggression to reduce the frequency or intensity of aggressive outbursts. Data collection and analysis Three authors independently selected studies and two authors independently extracted data. We calculated standardised mean differences (SMDs), with odds ratios (ORs) for dichotomous data. Main results Fourteen studies with data from 672 participants met the inclusion criteria. Five different antiepileptic drugs were examined. Sodium valproate/divalproex was superior to placebo for outpatient men with recurrent impulsive aggression, for impulsively aggressive adults with cluster B personality disorders, and for youths with conduct disorder, but not for children and adolescents with pervasive developmental disorder. Carbamazepine was superior to placebo in reducing acts of self-directed aggression in women with borderline personality disorder, but not in children with conduct disorder. Oxcarbazepine was superior to placebo for verbal aggression and aggression against objects in adult outpatients. Phenytoin was superior to placebo on the frequency of aggressive acts in male prisoners and in outpatient men including those with personality disorder, but not on the frequency of ‘behavioral incidents’ in

    1988-08-01

    The popular notion that a tendency to develop low levels of blood glucose is the cause of a range of behavioral problems is reviewed. It is concluded that it is inappropriate to use the glucose tolerance test as a test of the tendency to develop reactive hypoglycemia. Instead, a meal tolerance test, in which glucose is administered in the presence of fat and protein, should be the method of choice. The use of a meal tolerance test strongly suggests that reactive hypoglycemia rarely results, except in a few exceptional individuals. Three situations are described in which a correlation between a tendency to develop moderately low levels of blood glucose during a glucose tolerance test (not hypoglycemic values) and the tendency to act aggressively have been reported. The significance of these data is unclear but several possible mechanisms by which glucose may influence behavior are discussed. PMID:3053477

    This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. PMID:21186935

    Early and aggressive fluid therapy is critical in correcting the metabolic complications associated with calf diarrhea. Oral electrolyte therapy can be used with success in calves, but careful consideration should be given to the type of oral electrolyte used. Electrolyte solutions with high osmolalities can significantly slow abomasal emptying and can be a risk factor for abomasal bloat in calves. Milk should not be withheld from calves with diarrhea for more than 12 to 24 hours. Hypertonic saline and hypertonic sodium bicarbonate can be used effectively for intravenous fluid therapy on farms when intravenous catheterization is not possible. PMID:24980729
