    To test the chemical-physical properties and apatite-forming ability of experimental fluoride-doped calcium silicate cements designed to create novel bioactive materials for use in endodontics and oral surgery. A thermally treated calcium silicate cement (wTC) containing CaCl(2) 5%wt was modified by adding NaF 1%wt (FTC) or 10%wt (F10TC). Cements were analysed by environmental scanning electron microscopy with energy-dispersive X-ray analysis, IR and micro-Raman spectroscopy in wet conditions immediately after preparation or after ageing in a phosphate-containing solution (Dulbecco's phosphate-buffered saline). Calcium and fluoride release and pH of the storage solution were measured. The results obtained were analysed statistically (Tukey's HSD test and two-way anova). The formation of calcium phosphate precipitates (spherulites) was observed on the surface of 24 h-aged cements and the formation of a thick bone-like B-type carbonated apatite layer (biocoating) on 28 day-aged cements. The rate of apatite formation was FTC>F10TC>wTC. Fluorapatite was detected on FTC and F10TC after 1 day of ageing, with a higher fluoride content on F10TC. All the cements released calcium ions. At 5 and 24 h, the wTC had the significantly highest calcium release (Pfluoride release at all times (Pfluoride accelerated apatite formation on calcium silicate cements. Fluoride-doped calcium silicate cements had higher bioactivity and earlier formation of fluorapatite. Sodium fluoride may be introduced in the formulation of mineral trioxide aggregate cements to enhance their biological behaviour. F-doped calcium silicate cements are promising bone cements for clinical endodontic use. © 2011 International Endodontic Journal.

    Full Text Available Fluorapatite, Ca10(PO46F2. is a widely spread form of calcium phosphate present particularly in biological material. Human hard tissues contain crystals structurally related to apatite. Fluoride can be found in various natural sources and is also used for its beneficial action in caries prevention. Fluorapatite belongs to the spatial group P63/m (C6h2 and consists of 3 ions: F-, Ca2+, PO43-. In the present paper, we have carried out a crystallographic study of the fluorapatite structure and of the changes induced by the substitutions. The fluorapatite structure and the presence of a large number of ionic bonds make fluorapatite a very suitable host for many substitutents, some of them harmless for the human organism, some not. According to the substitution site, we can describe four types of substitution. The F- substitution, also called Type A substitution, is the main one, and the best known. Only the Ca2+ substitution implies changes in the crystal structure. However, some questions remain, in particular for the PO43- substitution, which is the main substitution present in the biological calcium phosphates.

    Several medical complications can occur after scoliosis surgery in children and adolescents. New surgical techniques have allowed greater degrees of scoliosis correction but have also increased the possibility of postsurgical deficit due to their greater aggressivity. We analyzed the early postsurgical complications of scoliosis surgery in a pediatric intensive care unit over a 10-year period. Seventy-six surgical procedures were performed. Of these, no complications occurred in 55 (73%). Chest X-ray revealed pulmonary atelectasia in 8 patients (10%) and pleural effusion in 7 patients (9%). Symptoms and signs of infection related to surgery were observed in only 6 children (8%). The absence of severe medical complications may be related to new surgical techniques and an experienced team.

    The purpose of the present study was to evaluate learning curves and short-term outcomes following laparoscopic surgery for early endometrial cancer in women of different body mass index (BMI) classes. Data from 227 women planned for laparoscopic surgery for presumed stage I endometrial cancer were collected retrospectively from a Danish gynecologic oncology unit. Surgery included laparoscopic hysterectomy and bilateral salpingo-oophorectomy with or without pelvic lymphadenectomy (PLA). Median length of operations was 60 min (range, 30-197) and 120 min (range, 60-230), depending on whether PLA was included. The median pelvic lymph node yield was 18 (range, 7-42). For staging with PLA there was a learning curve when measured as operative time as well as lymph node yield, and a level of proficiency was not reached after 40 operations. The women had a perioperative complication rate of 4.5% and a median hospital stay of one night. Postoperative complication rate was 12%, comprising vaginal cuff hematoma (3.1%), vaginal cuff rupture (0.9%), trocar hernia (1.3%), ureter lesion (0.4%), bowel lesion (0.4%), reoperation (0.9%) and other complications (4.5%). All peri- and postoperative outcomes were independent of BMI classes. Our data suggest that laparoscopic surgery for early endometrial cancer is feasible and safe. With increasing surgeon's experience there is a significant decrease in operative time and increase in the number of lymph nodes harvested. In experienced hands, either operative time, complications or length of stay are not affected by increasing BMI, even when women are morbidly obese. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    In order to produce stable aqueous fluorapatite (FA) suspensions, its surface reactivity in an aqueous solution having two initial pH values with a concentration of ammonium polyacrylate (NH{sub 4}PA) was investigated as a function of time. The influence of the slip viscosity on the casting rate and the microstructure of the resultant green slip cast compacts was determined. Upon the FA introduction in the aqueous solutions, an initial release of F anions located at the surface was found, which was not dependent of the pH and the presence of dispersant. The increase in the initial pH of the solution above 7 and/or the addition of NH{sub 4}PA markedly reduced the Ca{sup ++}/ H{sup +} exchange reaction rate. As a result, well-stabilized concentrated aqueous suspensions could be obtained at pH close to 9. The greater permeability of cakes produced from slips with high viscosity values (0.5 wt% PVA) increased the casting rate. (author)

    Fluorapatite glass-ceramics have been shown to be excellent candidates as scaffold materials for bone grafts, however, scaffold production by sintering is hindered by concurrent crystallization of the glass. Objective, our goal was to investigate the effect of Ca/Al ratio on the sintering behavior of Nb-doped fluorapatite-based glasses in the SiO2-Al2O3-P2O5-MgO-Na2O-K2O-CaO-CaF2 system. Methods, glass compositions with Ca/Al ratio of 1 (A), 2 (B), 4 (C) and 19 (D) were prepared by twice melting at 1525°C for 3h. Glasses were either cast as cylindrical ingots or ground into powders. Disk-shaped specimens were prepared by either sectioning from the ingots or powder-compacting in a mold, followed by heat treatment at temperatures ranging between 700 and 1050°C for 1h. The density was measured on both sintered specimens and heat treated discs as controls. The degree of sintering was determined from these measurements. Results and Significance XRD showed that fluorapatite crystallized in all glass-ceramics. A high degree of sintering was achieved at 775°C for glass-ceramic D (98.99±0.04%), and 900°C for glass-ceramic C (91.31±0.10). Glass-ceramics A or B were only partially sintered at 1000°C (63.6±0.8% and 74.1±1.5%, respectively). SEM revealed a unique microstructure of micron-sized spherulitic fluorapatite crystals in glass-ceramics C and D. Increasing the Ca/Al ratio promoted low temperature sintering of fluorapatite glass-ceramics, which are traditionally difficult to sinter.

    A retroauricular approach is routinely used for treating chronic otitis media. The incidence of surgical site infections after ear surgery is around 10% in contaminated or dirty procedures. This observational prospective study describes surgical site infections after chronic otitis media surgery with the retroauricular approach and investigated their potential predictive factors. This observational prospective study included patients suffering from chronic otitis media and eligible for therapeutic surgery with a retroauricular approach. During follow-up, surgical site infections were defined as "early" if occurring within 30 days after surgery or as "late" if occurring thereafter. The data of 102 patients were analysed. Concerning early surgical site infections, four cases were diagnosed (3.9%) and a significant association was found with preoperative antibiotic therapy, wet ear at pre-operative examination, class III (contaminated) in the surgical wound classification, NNIS (National Nosocomial Infection Surveillance) index > 1, and oral post-operative antibiotic use. Seven late surgical site infections were diagnosed (7.1%) between 90 and 160 days after surgery and were significantly correlated to otorrhoea during the 6 months before surgery, surgery duration ≤60 minutes, canal wall down technique and use of fibrin glue. Surgical site infections after chronic otitis media surgery seem to be associated with factors related to the inflammatory state of the middle ear at the time of surgery in early infections and with chronic inflammation in late infections. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    Children with early surgery for congenital heart disease (CHD) are known to have impaired neurodevelopment; their performance on school-age achievement tests and their need for special education remains largely unexplored. The study aimed to determine predictors of academic achievement at school age and placement in special education services among early CHD surgery survivors. Children with CHD surgery at codes. Predictors for achieving proficiency in literacy and mathematics and the receipt of special education were determined. Two hundred fifty-six children who attended Arkansas public schools and who had surgery as infants were included; 77.7 % had either school-age achievement-test scores or special-education codes of mental retardation or multiple disabilities. Scores on achievement tests for these children were 7-13 % lower than those of Arkansas students (p < 0.01). They had an eightfold increase in receipt of special education due to multiple disabilities [odds ratio (OR) 10.66, 95 % confidence interval (CI) 4.23-22.35] or mental retardation (OR 4.96, 95 % CI 2.6-8.64). Surgery after the neonatal period was associated with decreased literacy proficiency, and cardiopulmonary bypass during the first surgery was associated with decreased mathematics proficiency. Children who had early CHD surgery were less proficient on standardized school assessments, and many received special education. This is concerning because achievement-test scores at school age are "real-world" predictors of long-term outcomes.

    The effect of fluorapatite addition on the mechanical properties of tricalcium phosphate - 50 wt% zirconia composites was investigated during the sintering process. The Brazilian test was used to measure the mechanical resistance of bioceramics. The mechanical properties of composites increase with the sintering temperature and with fluorapatite additive. At 1400°C, the fluorapatite additive ameliorates the densification and the mechanical resistance of tricalcium phosphate - 50 wt% zirconia composites. The 31P magic angle spinning nuclear magnetic resonance analysis of tricalcium phosphate - zirconia composites sintered with fluorapatite additives reveals the presence of tetrahedral P sites.

    Hyponatraemia is a common complication in patients undergoing neurosurgery. It can be caused either by the syndrome of inappropriate secretion of antidiuretic hormone or by the cerebral salt-wasting syndrome (CSWS). CSWS frequently occurs in patients suffering from subarachnoid haemorrhage and brain injury, but it is rare after pituitary tumour surgery. However, this diagnostic possibility should be considered as these disorders require specific treatment and have different prognoses. In this article, we present a case of acute and early hyponatraemia caused by CSWS after pituitary tumour surgery. We also revise the aetiology, mechanisms, differential diagnosis and treatment of hyponatraemia after pituitary surgery.

    Prediction of complications in surgery is commonly done. There are conflicting reports concerning the usefulness of risk scales (P-POSSUM, APACHE, SAPS, ASA, Goldman, etc.) in vascular surgery. We decided to take a fresh look at preoperative risk factors of early death in the context of the usefulness of some parameters which have not been included in existing risk calculators. The study group consisted of 1270 patients treated at the Department of Vascular Surgery, General Surgery, and Angiology, Pomeranian Medical University in Szczecin, during one year. METHOD This was a prospective non-randomized study. All data recorded at admission and data from P-POSSUM, ASA, Goldman, and ECOG-Zubroda-WHO scales were analyzed. Statistics were done with discriminant, multivariate, and logistic tests. There were 42 early deaths in the group. The following independent risk factors were involved in early death: ASA > 2 (OR = 18.31), persistent atrial fibrillation (OR = 5.75), leukocytosis (OR = 13.31), glomerular filtration rate (GFR) SIRS) (OR = 11.36), emergency admission (OR = 38.62), critical limb ischemia (OR = 4.87), acute limb ischemia (OR = 8,98), abdominal aortic aneurysm (OR = 4.4), and ruptured aortic aneurysm (OR = 10.59). Logistic regression exposed the influence of five factors: ASA III, ASA IV, persistent atrial fibrillation, leukocytosis, GFR surgery need to be "refreshed". Creation of the Polish National Vascular Surgery Register seems to be unavoidable.

    Success of osteogenesis in bone graft procedures can be enhanced by inhibiting oral bacterial infections through the use of prophylactic bacteriostatic fluoride within the grafting environment. Ideally, the fluoride ion should be chemically sequestered and thus unavailable unless needed at times during the process of early infection. As fluoride within fluorapatite is tightly bound at neutral pH and becomes available only during acidic conditions, fluorapatite is an ideal store for the fluoride ion which becomes released for bacteriostasis only during an acidic environment found with incipient bacterial infection. The purpose of this investigation was to compare the histologic properties of new bone formed surrounding fluorapatite (FA)-coated microcrystalline hydroxyapatite (HA) grafting material with comparable bone formed following the use of control HA material (OsteoGen, Impladent, Ltd, Holliswood, NY). The results of histologic analysis within dog studies here showed no detectable difference in new bone following therapeutic grafting procedures using each of the above 2 mineral coatings.

    Full Text Available Introduction: Video-assisted thoracoscopic surgery (VATS lobectomy is the anatomical resection of a whole lobe ofthe lung followed by removal of the lymph nodes from the mediastinum using a thoracoscope and an access incision(small thoracotomy ≤ 5 cm without using the rib spreader. Aim: To present the early experience with VATS lobectomy. Material and methods: Five patients were treated surgically using the VATS technique of anatomical lung resection atthe 2nd Department of Surgery, Pavol Jozef Šafárik University, University Hospital of L. Pasteur, Košice, (Slovak Republicwithin 12 months from 10.2008 to 10.2009. Lobectomy was performed in 4 patients and pneumonectomy in 1 patient. Results: The mean operating time was 120 min (range 80-170 min. Following lobectomy a drain was inserted into thepleural cavity in 4 cases, whereas there was no drainage after 1 pneumonectomy. Drains were removed 2-5 days afterthe surgery. Four patients suffered from lung carcinoma (1 squamous cell carcinoma, 3 adenocarcinomas; 1 patienthad chondroid hamartoma. Postoperative condition was good in all patients. There were no early complications andpatients were released home on the 6th postoperative day on average. Conclusions: The advantages of VATS lobectomy have been widely discussed. There is a consensus that in elderlypatients with non-small cell lung cancer VATS lobectomy accompanied by mediastinal lymphadenectomy reduces theincidence of complications after the surgery and patients recover faster.

    Crystalline fluorapatite-coated hydroxyapatite (FA-HA) is studied using scanning electron microscopy (SEM), X-ray diffraction (XD), energy dispersive X-ray analysis (EDX), and EDX analysis mapping (EDXM). Fluoridated HA (fluorapatite) was prepared by reacting resorbable synthetic HA (OsteoGen, Impladent, Ltd, Holliswood, NY) with 4.3% sodium fluoride (NaF) for 2 minutes. After washing and drying, the resultant powder was subjected to physical property analysis using the methods listed above. SEM showed little evidence of surface change. Changes, if any, consisted of a slightly more distinct crystalline clarity on the surface of the FA sample. XD patterns showed significant random noise dispersion of the untreated HA sample compared with the lack of noise patterns in the treated FA sample. Characteristic monetite peaks were noted in analysis of the nontreated HA control sample, whereas there was no evidence of monetite in XD analysis of the treated FA material. It was determined that the fluoridation reaction, as described, served as a purification procedure of the initial HA reagent to eliminate a more soluble monetite contaminant. Also, the reaction of fluoride ion with surface HA (whether it be from or a combination of dissolution-reapposition or isomorphic substitution) produces a more purified, crystalline FA sample that was characterized by a more characteristic and sharp XD pattern. EDX analysis of the FA sample revealed a fluoride peak at 0.70 KeV that was not seen in the nonfluoridated control. EDX mapping showed an evenly distributed needle-like crystalline-shaped particulate pattern over the entire surface of the FA sample, which was lacking in the HA control. From a variety of analytic methods (as described), it was concluded that reaction of synthetic resorbable HA with 4.3% NaF solution at neutral pH produces FA-coated HA.

  19. Conservative surgery and radiation for early-stage breast cancer.

    In selected patients with early-stage breast cancer, conservative surgery and radiation represent an alternative equal to mastectomy in terms of local recurrence, distant metastasis, survival, and long-term complications. Patients with early-stage breast cancer who are candidates for conservative surgery and radiation include those whose primary tumor is less than 4 to 5 cm in size without evidence of gross multicentricity or diffuse microcalcifications. Patients with an extensive intraductal component may be appropriate candidates provided that margins of resection are negative. Young age is not a contraindication to the conservative treatment. A preexisting history of collagen vascular disease or prior mantle irradiation for Hodgkin's or non-Hodgkin's lymphoma represents a contraindication to conservative surgery and radiation because of the potential for severe complications. An additional contraindication is the pregnant woman in whom delivery cannot be accomplished before the initiation of radiation. Mammography is essential in the pretreatment evaluation and posttreatment follow-up of the conservatively treated patient. The goal of the pretreatment mammogram is to assess the extent of disease in the ipsilateral breast as well as to evaluate the contralateral breast. In patients who present with microcalcifications, a postbiopsy mammogram before radiation is essential to document complete removal of all malignant-appearing microcalcifications. Mammography is an essential part of the follow-up program in order to detect a recurrence in the treated breast as well as a cancer in the contralateral breast cancer. The optimal interval for follow-up mammography has not been determined, although programs employing mammography on a yearly basis after treatment have been associated with the detection of early recurrences and excellent survival after salvage mastectomy for these recurrences.

    To identify risk factors for serious and specific early complications of laparoscopic gastric bypass surgery using a large national cohort of patients. Bariatric procedures are among the most common surgical procedures today. There is, however, still a need to identify preoperative and intraoperative risk factors for serious complications. From the Scandinavian Obesity Surgery Registry database, we identified 26,173 patients undergoing primary laparoscopic gastric bypass operation for morbid obesity between May 1, 2007, and September 30, 2012. Follow-up on day 30 was 95.7%. Preoperative data and data from the operation were analyzed against serious postoperative complications and specific complications. The overall risk of serious postoperative complications was 3.4%. Age (adjusted P = 0.028), other additional operation [odds ratio (OR) = 1.50; confidence interval (CI): 1.04-2.18], intraoperative adverse event (OR = 2.63; 1.89-3.66), and conversion to open surgery (OR = 4.12; CI: 2.47-6.89) were all risk factors for serious postoperative complications. Annual hospital volume affected the rate of serious postoperative complications. If the hospital was in a learning curve at the time of the operation, the risk for serious postoperative complications was higher (OR = 1.45; CI: 1.22-1.71). The 90-day mortality rate was 0.04%. Intraoperative adverse events and conversion to open surgery are the strongest risk factors for serious complications after laparoscopic gastric bypass surgery. Annual operative volume and total institutional experience are important for the outcome. Patient related factors, in particular age, also increased the risk but to a lesser extent.

    Full Text Available Background: While limb salvage surgery has long been established as the standard of care for osteosarcoma, large studies from Indian centers are few. Given the diverse socio economic milieu of our patients, it becomes significant to determine the feasibility and outcome of management of osteosarcoma in our population. We analyzed the early outcome of limb salvage surgery with multimodality treatment of osteosarcoma of the extremity/girdle bones at a tertiary North Indian Cancer Centre. Materials and Methods: A total of 51 limb salvage surgeries performed during the months between November 2008 and November 2012 were studied. Neoadjuvant/adjuvant chemotherapy was given by the pediatric/adult medical oncology teams as applicable. The mean followup was 19.45 months (range 2-50 months. The oncological outcome was correlated with age, sex, size of tumor, stage at presentation, site, histological subtype, type of chemotherapy protocol followed and necrosis seen on postoperative examination of resected specimen. The functional outcome of the patients was evaluated using the musculoskeletal tumor society (MSTS scoring system. Results: Out of a total of 37 males and 14 females with an average age of 18.8 years, the 3 year overall survival was 66% and 3 year event free survival was 61.8%. In this group of patients with a short followup, a better oncological outcome was associated with good postoperative tumor necrosis, nonchondroblastic histology and age <14 years. The average MSTS score was highest in patients with proximal or distal femur prosthesis and the lowest in patients undergoing a knee arthrodesis. Conclusion: The present study shows oncological and functional outcomes of limb salvage combined with chemotherapy in Indian patients with osteosarcoma comparable to those in world literature. Larger studies on Indian population with longer followup are recommended.

    Titanium/fluorapatite (Ti/FA) composites with various FA additions were fabricated by powder metallurgy.The decomposition of FA during sintering was accelerated by the presence of Ti.The main reaction products of FA and Ti were identified as CaO,Ti phosphides,and CaTiO3.The addition of FA significantly inhibited the densification of Ti.The in vitro bioactivity of the composites was evaluated in a simulated body fluid (SBF).After immersion into the SBF,all the Ti/FA composites induced nucleation and growth of bone-like carbonated apatite on the surface.Co-precipitation of CaCO3 and Mg(OH)2 was also detected on the surface of the composite with high FA addition at an early stage of immersion.Furthermore,the release of fluorine ions from the composite was confirmed,which could promote bone regeneration and retard the formation of caries in the biological environment.The in vitro behavior was attributed to multiple factors,including the surface conditions and the constituents of the composite.The results demonstrated that the Ti/FA composites were bioactive in nature even with a low FA addition and they could introduce the benefit of fluorine ions in the service.

    A fast, simple and sustainable method based on choline chloride-urea deep eutectic solvent (known as Reline) was employed to synthesize nanosized fluorapatite (FA) particles. Using XRD, FESEM, TEM, EDS, and FTIR, the formation of FA nanoparticles with average crystal size of ~34nm, percent crystallinity of 93%, particle size of ~45nm, and high crystal, elemental, and structural purity was confirmed. The MTT cytotoxicity assay endorsed the non-toxicity of as-synthesized FA nanoparticles. The good biocompatibility, osteogenity and mineralization ability of as-synthesized FA nanoparticles were confirmed by Alizarin red staining, Acridine orange staining and ALP activity tests. After synthesis of the nanoparticles, the Reline solvent was recovered successfully using freeze-drying method with 71% yield of recovery revealing the green, sustainable and economical nature of the developed synthesis method. According to the results, owing to its alkalinity, high ionic strength and 3D bulky configuration, the Reline solvent provides the optimum conditions required for formation of FA with maximum crystallinity and the particle size controlled in the nanometer range. Providing a simple, cost-effective, and green method for synthesis of FA nanoparticles with potential biological applications is the most innovative aspect of this study.

    In order to restore the badly carious lesion of human dental enamel, a crystalline paste of fluoride substituted apatite cement was synthesized by using the mixture of tetracalcium phosphate (TTCP), dicalcium phosphate anhydrous (DCPA) and ammonium fluoride. The apatite cement paste could be directly filled into the enamel defects (cavities) to repair damaged dental enamel. The results indicated that the hardened cement was fluorapatite [Ca(10)(PO(4))(6)F(2), FA] with calcium to phosphorus atom molar ratio (Ca/P) of 1.67 and Ca/F ratio of 5. The solubility of FA cement in Tris-HCl solution (pH = 5) was slightly lower than the natural enamel, indicating the FA cement was much insensitive to the weakly acidic solutions. The FA cement was tightly combined with the enamel surface, and there was no obvious difference of the hardness between the FA cement and natural enamel. The extracts of FA cement caused no cytotoxicity on L929 cells, which satisfied the relevant criterion on dental biomaterials, revealing good cytocompatibility. In addition, the results showed that the FA cement had good mechanical strength, hydrophilicity, and anti-bacterial adhesion properties. The study suggested that using FA cement was simple and promising approach to effectively and conveniently restore enamel defects.

    The Matongo carbonatite intrusive body in the Neoproterozoic Upper Ruvubu alkaline plutonic complex (URAPC) in Burundi is overlain by an economic phosphate ore deposit that is present as breccia lenses. The ore exhibits evidence of supergene enrichment but also preserves textures related to the concentration of fluorapatite in the carbonatitic system. Magmatic fluorapatite is abundant in the ore and commonly occurs as millimeter-sized aggregates. It is enriched in light rare earth elements (LREE), which is especially apparent in the final generation of magmatic fluorapatite (up to 1.32 wt% LREE2O3). After an episode of metasomatism (fenitization), which led to the formation of K-feldspar and albite, the fluorapatite-rich rocks were partly brecciated. Oxygen and carbon isotope compositions obtained on the calcite forming the breccia matrix (δ18O = 22.1 ‰ and δ13C = -1.5 ‰) are consistent with the involvement of a fluid resulting from the mixing of magmatic-derived fluids with a metamorphic fluid originating from the country rocks. In a subsequent postmagmatic event, the carbonates hosting fluorapatite were dissolved, leading to intense brecciation of the fluorapatite-rich rocks. Secondary carbonate-fluorapatite (less enriched in LREE with 0.07-0.24 wt% LREE2O3 but locally associated with monazite) and coeval siderite constitute the matrix of these breccias. Siderite has δ18O values between 25.4 and 27.7 ‰ and very low δ13C values (from -12.4 to -9.2 ‰), which are consistent with the contribution of organic-derived low δ13C carbon from groundwater. These signatures emphasize supergene alteration. Finally, the remaining voids were filled with a LREE-poor fibrous fluorapatite (0.01 wt% LREE2O3), forming hardened phosphorite, still under supergene conditions. Pyrochlore and vanadiferous magnetite are other minerals accumulated in the eluvial horizons. As a consequence of the supergene processes and fluorapatite accumulation, the phosphate ore, which

    Flotation and adsorption performance of sodium oleate(NaOl)on powellite and fluorapatite were investigated in this work through micro-flotation tests, work of adhesion calculations, molecular dynamics simulation, micro-topography studies and FTIR measurements. The micro-flotation results show a similar flotation behaviors of powellite and fluorapatite under alkaline conditions, but a considerable difference in mineral recoveries in the pH range 2-7, which demonstrates the possibilities for separating powillite from fluorapatite under acidic conditions. The great difference in mineral recovery displays a good accordance with the obvious difference in the work of adhesion of powellite and fluorapatite at NaOl dosage range of 40-80 mg/L, obtained from flotation and contact angle measurements, respectively. The more negative interaction energy (ΔE) between NaOl and powellite/water interface from molecular dynamics simulation reveals a more easily adsorption of NaOl onto powellite than onto fluorapatite, which excellently matches with the results of flotation and work of adhesion. The results of micro-topography study shows that the adsorption of NaOl on powellite is mainly ascribed to the chemisorption of oleate ions with Ca2+ on powellite lattice or the precipitation of calcium dioleate agglomerates on powellite surface when it was in the solution without or with Ca2+, respectively. The FTIR measurements further confirm the chemisorption of oleate ions with Ca2+ active sites on powellite surface.

    Full Text Available Context Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. Method The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery were reviewed. Ninety-three (17.2% patients were male and 445 (82.8% were female. The ages of the patients ranged from 18 to 70 years (average = 46, and their body mass indices ranged from 34.6 to 77 kg/m2. Results Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5% patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. Conclusion The incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years. Contexto A cirurgia bariátrica tem mostrado ser o método mais eficaz de tratamento da obesidade grave.

    Under the formidable thrust of alternative management options for early stage lung cancer, the role of surgery in this disease subset has been questioned. Stereotactic body radiotherapy (SBRT) has been advocated as an ideal substitute for surgery not only in high risk patients or for the ones who refuse surgery but also in lieu of sublobar resection in otherwise fit patients. The therapeutic modalities for early stage NSCLC were compared as to warranting local control, enabling adequate tissu...

    AIM: To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases.METHODS: A total of 65 patients who underwent operations for gastric and colorectal diseases (mainly malignant diseases) were included in the study.Peripheral venous blood samples were collected at different times for analysis of estradiol, testosterone and progesterone. The only study endpoint was analysis of postoperative complications.RESULTS: Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients ( P = 0.027). There was no significant association of estradiol and progesterone with postoperative complications. Testosterone levels in complicated patients were significantly lower than in uncomplicated patients ( P < 0.05). Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate ( P < 0.05), and a lower value of testosterone at later times after surgery was a better predictor of complications.CONCLUSION: Patients with low testosterone level were prone to higher postoperative complications, which was evident in both sexes. However, further studies are necessary to support this result.

    Graphical abstract: - Highlights: • The neutralization method has been used for synthesis of silver-doped fluorapatite powders. • Particles of silver-doped fluorapatite samples are of nano size and homogenous in composition. • The Ag{sup +}-doped fluorapatite samples showed antibacterial effect against Kllebsiela pneumoniae, Staphylococcus aureus and Micrococcus luteus. • AFM studies showed that silver-doped sample causes considerable morphological changes of tested bacterial cells. - Abstract: Silver doped fluorapatite nanopowders were synthesised by neutralization method, which consists of dissolving Ag{sub 2}O in solution of HF and H{sub 3}PO{sub 4} and addition to suspension of Ca(OH){sub 2}. The powder XRD, SEM and FTIR studies indicated the formation of a fluorapatite nanomaterials with average length of the particles is about 80 nm and a width of about 15 nm. The FTIR studies show that carbonate content in samples is very small and carbonte ions substitute both phosphate and hydroxyl groups in the crystal structure of samples, forming AB-type fluorapatite. Antibacterial studies have demonstrated that all Ag{sup +}-doped fluorapatite samples exhibit bactericidal effect against pathogens: Staphylococcus aureus, Micrococcus luteus and Kllebsiela pneumoniae. Antibacterial activity increased with the increase of Ag{sup +} in the samples. The atomic force microscopy studies revealed extensive damage to the bacterial cell envelops in the presence of Ag{sup +}-doped fluorapatite particles which may lead to their death. The synthesized Ag{sup +}-doped fluorapatite nanomaterials are promising as antibacterial biomaterials in orthopedics and dentistry.

    2016-08-01

    Conclusion: Right anterolateral mini-thoracotomy minimally invasive technique provides excellent exposure of the mitral valve, even with a small atrium and offers a better cosmetic lateral scar which is less prone to keloid formation. In addition, minimally invasive right anterolateral mini-thoracotomy is as safe as median sternotomy for mitral valve surgery, with fewer complications and postoperative pain, less ICU and hospital stay, fast recovery to work with no movement restriction after surgery. It should be used as an initial approach for mitral valve surgery. Furthermore, it was believed that less spreading of the incision, no interference with the diaphragm and less tissue dissection might improve outcomes, particularly respiratory function.

    To systematically review early surgery and the optimal timing of surgery in patients with infective endocarditis (IE), a search for foreign and domestic articles on cohort studies about the association between early surgery and infective endocarditis published from inception to January 2015 was conducted in the PubMed, EMBASE, Chinese Biomedical Literature (CBM), Wanfang and Chinese National Knowledge Infrastructure (CNKI) databases. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality of the method of the included studies was assessed. Then, the meta-analysis was performed using the Stata 12.0 software. Sixteen cohort studies, including 8141 participants were finally included. The results of the meta-analysis revealed that, compared with non-early surgery, early surgery in IE lowers the incidence of in-hospital mortality [odds ratio (OR) = 0.57, 95% confidence interval (CI) (0.42, 0.77); P = 0.000, I2 = 73.1%] and long-term mortality [OR = 0.57, 95% CI (0.43, 0.77); P = 0.001, I2 = 67.4%]. Further, performing operation within 2 weeks had a more favourable effect on long-term mortality [OR = 0.63, 95% CI (0.41, 0.97); P = 0.192, I2 = 39.4%] than non-early surgery. In different kinds of IE, we found that early surgery for native valve endocarditis (NVE) had a lower in-hospital [OR = 0.46, 95% CI (0.31, 0.69); P = 0.001, I2 = 73.0%] and long-term [OR = 0.57, 95% CI (0.40, 0.81); P = 0.001, I2 = 68.9%] mortality than the non-early surgery group. However, for prosthetic valve endocarditis (PVE), in-hospital mortality did not differ significantly [OR = 0.83, 95% CI (0.65, 1.06); P = 0.413, I2 = 0.0%] between early and non-early surgery. We concluded that early surgery was associated with lower in-hospital and long-term mortality compared with non-early surgical treatment for IE, especially in NVE.

    Systemic inflammatory response syndrome (SIRS) is a common complication after cardiovascular surgery that in severe cases can lead to multiple organ dysfunction syndrome and even death. We therefore set out to identify reliable early biomarkers for SIRS in a prospective small patient study for timely intervention. 21 Patients scheduled for planned cardiovascular surgery were recruited in the study, monitored for signs of SIRS and blood samples were taken to investigate biomarkers at pre-assigned time points: day of admission, start of surgery, end of surgery, days 1, 2, 3, 5 and 8 post surgery. Stored plasma and cryopreserved blood samples were analyzed for cytokine expression (IL1β, IL2, IL6, IL8, IL10, TNFα, IFNγ), other pro-inflammatory markers (sCD163, sTREM-1, ESM-1) and response to endotoxin. Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (pSIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (pSIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

    Fumaroles represent a very important potential habitat on Mars because they contain water and nutrients. Global deposition of volcanic sulfate aerosols may also have been an important soil-forming process affecting large areas of Mars. Here we identify alteration from the Senator fumarole, northwest Nevada, USA, and in low-temperature environments near the fumarole to help interpret fumarolic and acid vapor alteration of rocks and soils on Mars. We analyzed soil samples and fluorapatite, olivine, and basaltic glass placed at and near the fumarole in in situ mineral alteration experiments designed to measure weathering under natural field conditions. Using synchrotron X-ray diffraction, we clearly observe hydroxyl-carbonate-bearing fluorapatite as a fumarolic alteration product of the original material, fluorapatite. The composition of apatites as well as secondary phosphates has been previously used to infer magmatic conditions as well as fumarolic conditions on Mars. To our knowledge, the observations reported here represent the first documented instance of formation of hydroxyl-carbonate-bearing apatite from fluorapatite in a field experiment. Retreat of olivine surfaces, as well as abundant NH4-containing minerals, was also characteristic of fumarolic alteration. In contrast, alteration in the nearby low-temperature environment resulted in formation of large pits on olivine surfaces, which were clearly distinguishable from the fumarolic alteration. Raman signatures of some fumarolically impacted surfaces are consistent with detection of the biological molecules chlorophyll and scytenomin, potentially useful biosignatures. Observations of altered minerals on Mars may therefore help identify the environment of formation and understand the aqueous history and potential habitability of that planet.

    Full Text Available Abstract Background Changes to the structure of medical training worldwide require doctors to decide on their career specialty at an increasingly early stage after graduation. We studied trends in career choices for surgery, and the eventual career destinations, of UK graduates who declared an early preference for surgery. Methods Postal questionnaires were sent, at regular time intervals after qualification, to all medical qualifiers from all UK medical schools in selected qualification years between 1974 and 2005. They were sent in the first year after qualification, at year three and five years after qualification, and at longer time intervals thereafter. Results Responses were received from 27 749 of 38 280 doctors (73% at year one, 23 468 of 33151 (71% at year three, and 17 689 of 24 870 (71% at year five. Early career preferences showed that surgery has become more popular over the past two decades. Looking forward from early career choice, 60% of respondents (64% of men, 48% of women with a first preference for a surgical specialty at year one eventually worked in surgery (p Conclusions Surgery is a popular specialty choice in the UK. The great majority of doctors who progressed in a surgical career made an early and definitive decision to do so.

    Full Text Available Nowadays cervical cancer is diagnosed in many women who still want to have children. This led to the need to provide fertility-sparing treatments. The main goal is to maintain reproductive ability without decreasing overall and recurrence-free survival. In this article, we review data on procedures for fertility preservation, namely, vaginal and abdominal trachelectomy, less invasive surgery and neoadjuvant chemotherapy. For each one, oncological and obstetrical outcomes are analyzed. Comparing to traditionally offered radical hysterectomy, the overall oncologic safety is good, with promising obstetrical outcomes.

    Full Text Available Systemic inflammatory response syndrome (SIRS is a common complication after cardiovascular surgery that in severe cases can lead to multiple organ dysfunction syndrome and even death. We therefore set out to identify reliable early biomarkers for SIRS in a prospective small patient study for timely intervention. 21 Patients scheduled for planned cardiovascular surgery were recruited in the study, monitored for signs of SIRS and blood samples were taken to investigate biomarkers at pre-assigned time points: day of admission, start of surgery, end of surgery, days 1, 2, 3, 5 and 8 post surgery. Stored plasma and cryopreserved blood samples were analyzed for cytokine expression (IL1β, IL2, IL6, IL8, IL10, TNFα, IFNγ, other pro-inflammatory markers (sCD163, sTREM-1, ESM-1 and response to endotoxin. Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (p<0.001 at the end of surgery in all patients but could not distinguish between groups. Normalization of samples revealed significant increases in IL1β changes (p<0.05 and decreased responses to endotoxin (p<0.01 in the SIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (p<0.01. This small scale patient study could show that common sepsis markers PCT, CRP, IL6 and TNFα had low predictive value for early diagnosis of SIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

    AIM: To analyze the difference in disease course and need for surgery in patients with Crohn’s disease (CD). METHODS: Data of 506 patients with incident CD were analyzed (age at diagnosis: 31.5 ± 13.8 years). Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which includes incident CD patients diagnosed between January 1, 1977 and December 31, 2008. Follow-up data were collected until December 31, 2009. All patients included had at least 1 year of follow-up available. Patients with indeterminate colitis at diagnosis were excluded from the analysis. RESULTS: Overall, 73 patients (14.4%) required resective surgery within 1 year of diagnosis. Steroid exposure and need for biological therapy were lower in patients with early limited surgery (P < 0.001 and P = 0.09). In addition, surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores (P < 0.001, HR = 0.23). The need for reoperation was also lower in patients with early limited resective surgery (P = 0.038, HR = 0.42) in a Kaplan-Meier and multivariate Cox regression (P = 0.04) analysis. However, this advantage was not observed after matching on propensity scores (PLogrank = 0.656, PBreslow = 0.498). CONCLUSION: Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery, but reoperation rates did not differ.

    Full Text Available Preoperative severe renal impairment is included in the risk scores to predict out-come after open cardiac surgery. The purpose of this study was to assess the impact of pre-operative mild renal impairment on the early postoperative mortality after open heart surgery. Data of all cases of open cardiac surgery performed from January 2005 to June 2006 were collec-ted. Cases with preoperative creatinine clearance below 60 mL/min were excluded from the study. Data were retrospectively analyzed to find the impact of renal impairment on short-term outcome. Of the 500 cases studied, 47 had preoperative creatinine clearance between 89-60 mL/min. The overall mortality in the study cases was 6.8%. The mortality was 28.7% in those who developed postoperative ARF, 33.3% in those who required dialysis and 40.8% in those with preoperative mild renal impairment. Binary logistic regression analysis showed that female gender (P = 0.01, preoperative mild renal impairment (P = 0.007 as well as occurrence of multi organ failure (P < 0.001 were the only independent variables determining the early postoperative mortality after cardiac surgeries. Among them, preoperative mild renal impairment was the most significant and the best predictor for early postoperative mortality after cardiac surgery. Our study suggests that renal impairment remains a strong predictor of early mortality even after adjustment for several confounders.

    Abstract Persistence of postoperative radicular pain after surgery for multifocal disc herniation (MFDH) is a clinical problem. This study aims to evaluate the effects of a combined treatment approach compared with unilateral stabilization on early postoperative radicular pain in patients with MFDH. Age, sex, level of operation, clinical findings, and radicular pain visual analogue scale (VAS) scores before surgery in the early postoperative period and at 3 months after surgery were retrospectively reviewed for 20 cases of multifocal lumbar disc herniation. The combined approach (translaminar and far lateral) was used for 13 cases. Seven cases underwent transforaminal lumbar interbody fusion (TLIF) and unilateral transpedicular stabilization following total facetectomy. The mean age of the sample was 49.4 ± 10.1 years and the female-to-male ratio was 8:12. The mean VAS scores for radicular pain in cases treated with the combined approach were 8.2, 4.07, and 2.3 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean score for radicular pain improved by 50.4% in the early postoperative period and by 72% in the late postoperative period. The mean VAS scores for radicular pain in cases who underwent TLIF and unilateral stabilization after facetectomy were 8.4, 2.1, and 1.4 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean VAS score for radicular pain improved by 75% in the early postoperative period and by 83.3% in the late postoperative period. The combined approach is an effective alternative in cases with MFDH. TLIF and unilateral segmental stabilization provide substantial decompression and eliminate mechanical compression by conserving the height of the intervertebral foramen in the event that sufficient decompression is unable to obtain. We suggest that elimination of chemical mediators, particularly those causing pain in the dorsal ganglion, contributes to

    Full Text Available OBJECTIVE: This prospective randomized clinical study was conducted to evaluate the safety and tolerability of early oral feeding after colorectal operations. METHODS: A total of 199 patients underwent colorectal surgery and were randomly assigned to early feeding (n = 99 or a regular diet (n = 100. Patients’ characteristics, diagnoses, surgical procedures, comorbidity, bowel movements, defecation, nasogastric tube reinsertion, time of tolerance of solid diet, complications, and length of hospitalization were assessed. RESULTS: The two groups were similar in terms of gender, age, diagnosis, surgical procedures, and comorbidity. In the early feeding group, 85.9% of patients tolerated the early feeding schedule. Bowel movements (1.7±0.89 vs. 3.27±1.3, defecation (3.4±0.77 vs. 4.38±1.18 and time of tolerance of solid diet (2.48±0.85 vs. 4.77±1.81 were significantly earlier in the early feeding group. There was no change between the groups in terms of nasogastric tube reinsertion, overall complication or anastomotic leakage. Hospitalization (5.55±2.35 vs. 9.0±6.5 was shorter in the early feeding group. CONCLUSIONS: The present study indicated that early oral feeding after elective colorectal surgery was not only well tolerated by patients but also affected the postoperative outcomes positively. Early postoperative feeding is safe and leads to the early recovery of gastrointestinal functions.

    Full Text Available Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR.   Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-third esophageal cancer were randomly assigned to one of two groups. The first group consisted of 50 patients receiving standard chemoradiotherapy (Group A and then undergoing surgery, and the second group consisted of 50 patients undergoing surgery only (Group B. Patients were evaluated with respect to age, gender, clinical symptoms, type of pathology, time of surgery, perioperative blood loss, and number of lymph nodes resected as well as early post-operative complicate including leakage at the anastomosis site, chylothorax and pulmonary complications, hospitalization period, and mortality rate within the first 30 days after surgery.   Results: The mean age of patients was 55 years. Seventy-two patients had squamous cell carcinoma (SCC and 28 patients had adenocarcinoma (ACC. There was no significant difference between the two groups with respect to age, gender, time of surgery, complications including anastomotic leakage, chylothorax, pulmonary complications, cardiac complications, deep venous thrombosis (DVT, or mortality. However, there was a significant difference between the two groups regarding hospital stay, time of surgery, perioperative blood loss, and number of lymph nodes resected.   Conclusion:  The use of NACR did not increase early post-operative complications or mortality among patients with esophageal cancer.

    Laparoscopic surgery for this disease is not widely spread due to difficulties in its procedure. We started a laparoscopic procedure for this disease since 2011, and the robotic surgery since 2012. The aim of this study is to assess early results of these procedures. We have operated seven cases from September 2011 through December 2013. First two cases were performed by laparoscopic procedure, and following cases were done by robotically assisted surgery. Of these cases, the perioperative outcome and short-term postoperative morbidity were evaluated. Their average age was 43.6 years old (20-64 years old), and male-female ratio was 2:5. Todani classification was type 1 in all cases. The operation time was 321 min in laparoscopic cases, while 489 min in robotic surgery cases. One case of robotic surgery developed postoperative intestinal obstruction of the biliary limb, requiring laparoscopic adhesiolysis. Pancreatic fistula and anastomotic leakage have not been observed. The robotic surgery for the congenital dilatation of the bile duct is feasible and is a theoretically useful option, especially for hepatico-jejunostomy. On the other hand, the limitation of energy devices, high running cost, and time consumption remain questionable.

    Despite the implementation of multimodal bundles of care in hospitalised patients, post-operative sepsis in patients with cancer still accounts for a significant burden of illness and substantial healthcare costs. Patients undergoing surgery for cancer are at particular risk of sepsis due to underlying malignancy, being immunocompromised associated with cancer management and the complexity of surgical procedures performed. In this review, we evaluate the burden of illness and risks for sepsis following surgery for cancer. Current evidence supporting standardised strategies for sepsis management (including early recognition and resuscitation) is examined together with challenges in implementing quality improvement programs.

    More than 75% of respondents to an Eastern Association for the Surgery of Trauma survey felt that barriers to research had increased and that acute care surgeon (ACS) academic productivity had decreased. Recent data confirm this impression and show lower academic productivity of junior ACS faculty compared with peers in other general surgical fields. The purpose of this study was to determine if early career acute care surgery research scholarships are associated with improved ACS academic productivity. Faculty data at the Top 55 National Institutes of Health (NIH)-funded departments of surgery (Top 55) were obtained using SCOPUS, NIH, department, and professional society databases. Academic productivity was measured using total publications, citations, and the Hirsch index. Scholarship recipients from the American Association for the Surgery of Trauma and Eastern Association for the Surgery of Trauma were identified. A total of 4,101 surgical faculty (8.3% ACS) who belong to the Top 55 NIH-funded departments of surgery and 85 scholarship recipients were identified. After merging, 34 scholarship recipients (40%) were current faculty at a Top 55 NIH-funded department of surgery, and 24 of those (71%) were ACS faculty. Scholarship recipients had higher median total publications compared with nonrecipients at assistant and associate ranks but not at full professor rank. For all ranks, scholarship recipients were more likely to have NIH funding compared with nonrecipients (33% vs. 11%, p publications, with an average of 89 more publications over a career (p ACS faculty in Top 55 NIH-funded departments of surgery. Among junior ACS faculty, recipients are associated with increased academic productivity and NIH funding. To fill the academic productivity gap among junior ACSs, professional organizations should consider increasing research funding scholarships for promising investigators.

    Full Text Available An investigation was conducted into the influence of the amino acids as organic modifiers in the facile synthesis of metal incorporated fluorapatites (FAp and their properties. The nanostructured Sm doped fluorapatites (Sm-FAp were prepared by a co-precipitation method using four different amino acids, namely glutamic acid, aspartic acid, glycine and histidine. The materials were characterized by various techniques including X-ray diffraction (XRD, Fourier transform infra-red spectroscopy (FT-IR, field emission scanning electron microscopy (FE-SEM, energy-dispersive X-ray spectroscopy (EDX, high resolution transmission electron microscopy (HR-TEM, N2-adsorption/desorption isotherm, temperature programmed desorption (TPD and fluorescence spectrophotometry. Under similar conditions, Sm-FAp prepared using different amino acids exhibited distinctly different morphological structures, surface area and pore properties. Their activity as catalysts was assessed and Sm-FAp/Glycine displayed excellent efficiency in the synthesis of 1,2,4-triazole catalyzing the reaction between 2-nitrobenzaldehyde and thiosemicarbazide with exceptional selectivity and 98% yield in a short time interval (10 min. The study provides an insight into the role of organic modifiers as controllers of nucleation, growth and aggregation which significantly influence the nature and activity of the catalytic sites on Sm-FAp. Sm-FAp could also have potential as photoactive material.

    We investigated the hypothesis that the cyanobacterium Anabaena PCC 7120 is able to use fluorapatite (FAP) as sole phosphate source for growth. In the experimental setup the dissolution of FAP was tested in a phosphate free growth medium in the presence and absence of the Anabaena, as well as the cell free supernatant of an Anabaena culture. The results were compared with that of an Anabaena culture grown without fluorapatite. Parameters measured were pH, dissolved P and Ca, as well as cell density. The FAP grains were analyzed using SEM and XPS. Additionally, the differential expression of secreted proteins in cultures with and without dissolved phosphate was examined. P-limited Anabaena cultures tend to aggregate and in the presence of FAP the cells attached themselves to the mineral grains. The cultures benefit from the presence of FAP. The cells have a very effective P-uptake system that is able to take up dissolved phosphate very efficiently and draw the concentrations down to very low levels. Furthermore, the SEM analysis of FAP showed an etching of the mineral grains in the samples from the Anabaena cultures. The mechanism of apatite dissolution with and without Anabaena will be discussed in terms of these experimental observations.

    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

    To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

    To investigate the effect of early rehabilitation on neurofunctional outcome after surgery in chil-dren with spinal tumors, this study reviewed the medical charts and radiographic records of 70 pediatric patients (1-17 years old) who received spinal tumor surgical removal. The peddiatric patients received rahabilitation treatment at 4 (range, 2-7) days after surgery for 10 (range, 7-23) days. Results from the Modiifed McCormick Scale, Functional Independence Measure for Chil-dren, American Spinal Injury Association Impairment Scale and Karnofsky Performance Status Scale demonstrated that the sensory function, motor function and activity of daily living of pedi-atric children who received early rehabilitation were signiifcantly improved. Results also showed that tumor setting and level localization as well as patients’s clinical symptoms have no inlfuences on neurofunctional outcomes.

    The present study assessed the safety and efficacy of continuous venovenous hemodialysis (CVVHD) early after cardiac surgery. Retrospective database and medical record review. University teaching hospital. Forty-five dialysis-dependent patients who underwent cardiac surgery with cardiopulmonary bypass. CVVHD was begun postoperatively after confirmation of hemostasis, irrespective of circulatory status. In the last 5 patients, the ratio of extravascular lung water (EVLW) to intrathoracic blood volume (ITBV) was measured using a single-indicator thermodilution catheter and compared with patients of normal renal function undergoing cardiac surgery. CVVHD was started at 4 hours after ICU admission. The maximum decrease in blood pressure within 60 minutes after initiation of CVVHD was 11 +/- 9 mmHg in the unstable hemodynamics group (defined as patients who required continuous intravenous adrenaline or intra-aortic balloon pump on admission to the ICU [n = 15]) and 7 +/- 8 mmHg in the stable hemodynamics group (n = 30, not significant). Circulatory status and oxygenation improved significantly 12 hours after CVVHD initiation in the unstable hemodynamics group. Blood volume from the chest tube did not increase after CVVHD. Early mortality (2.2%) was lower than that reported previously. The EVLW/ITBV ratio after ICU admission in dialysis-dependent patients was significantly higher than in patients with normal renal function. Early CVVHD after cardiac surgery in dialysis-dependent patients was safe and effective. There was no associated increased postoperative bleeding or hemodynamic instability. Fluid removal improved respiratory status, particularly in patients requiring circulatory assistance, and overall early morality rates were lower that those previously published.

    Abstract The aim of this study is to determine whether surgery offers protection against early subtalar arthrodesis in displaced intraarticular calcaneal fractures. Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014. The modified Jadad scale was used for trial quality and effective data were pooled for meta-analysis. Study results related to early subtalar arthrodesis were extracted and risk assessment was combined with surgical treatment and nonsurgical treatment. The primary analysis included 4 studies and 966 participants. The estimated overall risk ratio was 4.40 (95% confidence interval 2.67–7.39), indicating the incidence of early subtalar arthrodesis in nonsurgical group is 4.4 times the surgical group. The results showed that surgical treatment was superior to nonsurgical treatment in protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures (Z = 5.600, P < 0.001). Surgery offers protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures. PMID:26559281

    The purpose of this study was to assess the efficacy of tolvaptan, a vasopressin V2 receptor antagonist, for the management of postoperative surgical fluid retention after heart valve surgery. This was a prospective observational study of 64 patients with heart valve disease who underwent valve surgery between 2013 and 2014. Those in the tolvaptan group received tolvaptan in addition to conventional diuretic therapy. The results were compared to the results of 55 patients who underwent heart valve surgery between 2007 and 2010 and received conventional postoperative diuretics alone. The time to return to the preoperative BW was significantly shorter in the patients who received tolvaptan (6.1 ± 3.8 vs. 8.7 ± 6.7 days, p fluid retention during the early postoperative stage in cardiac surgery patients, without increased renal failure or abnormal electrolyte levels. This new type of diuretic therapy may be a suitable option for postoperative fluid management in patients undergoing cardiac surgery.

    2016-01-01

    Background Single-port video-assisted thoracic surgery (SPVATS) emerged several years ago as a new, minimally invasive surgery for diseases in the field of respiratory surgery, and is increasingly becoming a subject of interest for some thoracic surgeons in Europe and Asia. However, the adoption rate of this procedure in the United States and Japan remains low. We herein reviewed our experience of SPVATS for early lung cancer in our center, and evaluated the safety and minimal invasiveness of this technique. Methods We retrospectively analyzed patients who had undergone SPVATS for pathological stage I lung cancer in Nippon Medical School Chiba Hokusoh Hospital between September 2012 and October 2015. In SPVATS, an approximately 4-cm incision was made at the 4th or 5th intercostal space between the anterior and posterior axillary lines. A rib spreader was not used at the incision site, and surgical manipulation was performed very carefully in order to avoid contact between surgical instruments and the intercostal nerves. The same surgeon performed surgery on all patients, and analyzed laboratory data before and after surgery. Results Eighty-four patients underwent anatomical lung resection for postoperative pathological stage I lung cancer. The mean wound length was 4.2 cm. Eighty-four patients underwent lobectomy and segmentectomy, respectively. The mean preoperative forced expiratory volume in 1 second (FEV1%) was 1.85%±0.36%. Our patients consisted of 49 men (58.3%) and 35 women (41.7%), with 64, 18, 1, and 1 having adenocarcinoma, squamous cell carcinoma, adenosquamous carcinoma, and small-cell lung cancer, respectively. The mean operative time was 175±21 min, operative blood loss 92±18 mL, and duration of drain placement 1.9±0.6 days. The duration of the postoperative hospital stay was 7.1±1.7 days, numeric rating scale (NRS) 1 week after surgery 2.8±0.6, and occurrence rate of allodynia 1 month after surgery 10.7%. No patient developed serious

    In a retrospective study of 397 children operated in the course of 10 years (1985-1995) on account of essential infantile esotropia the authors evaluate the effect of early surgery implemented before the age of two years on the quality of binocular vision as compared with a later operation. The group of children was divided into three sub-groups. Group A comprised 75 children with the operation during the first six months of life (mean 3.8 months), sub-group B 194 children with the operation at the age of 6-24 months and in group C 128 children operated at the age of 2-6 years (mean 3.56 years). In group A binocular vision was recorded in 80% children (15% superposition, 60% fusion, 5% stereopsy). In groups B binocular vision was recorded in 76% children (18% superposition, 50% fusion, 8% stereopsy). In group C simple binocular vision in the form of superposition was present in 24% and fusion only in 21% children. The results of binocular vision after surgery of essential infantile esotropia are in favour of early surgery, preferably by the age of 6 months, not later than at the age of 2 years. An essential part of comprehensive treatment is active and positive pleoptic and orthoptic care incl. supplementary surgical correction of residual horizontal or vertical deviations. Early surgery of an adequate extent with a safeguarded parallel position of the eyes implies in the long run more frequent achievement of a higher quality of binocular vision incl. stereopsy.

    Postoperative leaks are the most undesirable complication of bariatric surgery and upper gastrointestinal (GI) series are routinely ordered to rule them out. Despite the published literature recommending against its routine use, it is still being customarily used in Chile. To examine the usefulness of routine upper GI series using water-soluble iodinated contrast media for the detection of early postoperative leaks in patients undergoing bariatric surgery. A cohort of 328 patients subjected to bariatric surgery was followed from October 2012 to October 2013. Most of them underwent sleeve gastrectomy. Upper GI series on the first postoperative day were ordered to 308 (94%) patients. Postoperative leaks were observed in two patients, with an incidence of 0.6%. The sensitivity for upper GI series detection of leak was 0% and the negative predictive value was 99%. Routine upper GI series after bariatric surgery is not useful for the diagnosis of postoperative leak, given the low incidence of this complication and the low sensitivity of the technique.

    Full Text Available AIM: The research aims to determine the influence of early goal-oriented physical therapy program in combination with educational booklet and standard physical therapy without written instructions on functional mobility outcomes in patients after low back surgery. MATERIAL AND METHODS: Thirty patients with similar functional impairments were randomly divided into two groups, a control group (СG n = 10 and an experimental group (EG n = 20. The outcome measures include time to move from lying to sitting position, the TUG test and the 6-meter walk test. Rehabilitation program includes daily physical therapy with mild to moderate intensity, achieving sitting position and education sessions how to perform activities of daily living (ADL from the first day after surgery. RESULTS: There was a significant improvement from baseline in two groups for all performed tests (p < 0.001. Statistical significant differences between two groups for transfers in bed on discharge (p < 0.05, in one month (p < 0.01 and for TUG in one month (p < 0.05 were found. CONCLUSION: The study revealed that early rehabilitation program consists of therapeutic exercises and written educational booklet after low back surgery improves transfer abilities and basic activities in one month.

    Background Myocardial injury after non-cardiac surgery (MINS) is defined as troponin elevation of ≥0.03 ng/mL associated with 3.87-fold increase in early mortality. We sought to determine the impact of cardiology intervention on mortality in patients who developed MINS after general thoracic surgery. Methods A retrospective review was performed in patients over 5 years. Troponin was routinely measured and levels ≥0.04 ng/mL classified as positive. Data acquisition and mortality status was obtained via medical records and NHS tracing systems. Thirty-day mortality was compared on MINS cohort using Fisher’s exact square testing and logistic regression analysis. Results Troponin levels were measured in 491 (96%) of 511 patients. Eighty (16%) patients fulfilled the MINS criteria. Sixty-one (76%) received early cardiology consult and “myocardial infarction” stated in four (5%) patients. Risk assessment (for AMI) was undertaken; 20 (25%) patients were commenced on aspirin, four (5%) on β-blockers and one (1%) underwent percutaneous coronary intervention. Forty-nine (61%) patients received primary risk factor modifications and 26 (33%) had outpatient follow-up. There were no significant differences in the proportion of patients who died within 30 days post-operatively in the MINS group of 2.6% compared to the non-MINS group of 1.6% (P=0.625). The odds ratio for 30-day mortality in the MINS group was 1.69 (95% CI: 0.34 to 8.57, P=0.522). Conclusions MINS is common after general thoracic surgery. Early cardiology intervention reduced the expected hazard ratio of early death from 3.87 to an odds ratio of 1.69 with no significant difference in 30-day mortality for patients who developed MINS.

    It is presented the results of diagnostic and curative laparoscopic interventions in 33 patients with acute early adhesive small bowel obstruction. Ileus developed after surgical treatment (laparotomy) of different gynecological diseases. Laparoscopy appeared as the most informative diagnostic method to confirm diagnosis in all patients, to estimate state of abdominal cavity and small pelvis organs what can help to determine method of surgical treatment. Contraindications for laparoscopic surgery were identified in 12 (36.4%) patients and conversion to laparotomy was applied in this group. Postoperative complications were diagnosed in 1 (8.3%) patient. 2 (16.6%) patients died. Early adhesive ileus was resolved laparoscopically in 21 (63.6%) of 33 patients. Recurrent acute early adhesive ileus was detected in 1 (4.7%) patient.

    The purpose of this study was to evaluate the cytotoxicity of two formulations of hydroxyapatite (HA), namely fluorapatite (FA) and fluor-hydroxyapatite (FHA). HA is used as carrier material for antibiotics or anticancer drugs during treatment of bone metastasis. Negative control, represented by HA, was included for comparative purposes. Leukemia cells were used as a model cell line, and the effect of eluates of tested biomaterials on cell proliferation/viability and mechanism of antiproliferative activity were assessed. Study design attempted to reveal the toxicity of tested biomaterials with an emphasis to decide if tested biomaterials have promise for further studies in vivo. Results showed that eluates of FA and FHA inhibit the growth of leukemia cells and induce programmed cell death through mitochondrial/caspase-9/caspase-3-dependent pathway. Due to these differences compare to HA, it is concluded that FA and FHA have promise for evaluation of their behaviour in vivo.

    Full Text Available The process of enamel biomineralization is multi-step, complex and mediated by organic molecules. The lack of cells in mature enamel leaves it unable to regenerate and hence novel ways of growing enamel-like structures are currently being investigated. Recently, elastin-like protein (ELP with the analog N-terminal sequence of statherin (STNA15-ELP has been used to regenerate mineralized tissue. Here, the STNA15-ELP has been mineralized in constrained and unconstrained conditions in a fluoridated solution. We demonstrate that the control of STNA15-ELP delivery to the mineralizing solution can form layered ordered fluorapatite mineral, via a brushite precursor. We propose that the use of a constrained STNA15-ELP system can lead to the development of novel, bioinspired enamel therapeutics.

    Full Text Available high purity fluorapatite (FA with rod-like and spherical-like morphology was synthesized via sol-gel method. Chemical characterization of FA powders was done by XRD and FTIR analyses. Crystallite samples were calculated using Scherer method. Morphology of FA powders was investigated with TEM and SEM images. The results revealed that increasing the time of hydrolysis of phosphate sols significantly decreased the gelation time of FA sols. Also, mixing temperature of P and Ca sols affects the gelation time of samples and increasing pH decreases the gelation time of FA sols. Morphological and chemical characterization of samples showed that the FA powders have high purity and rod-like and spherical-like morphology.

    Glass-ceramics in the diopside (CaMgSi2O6)-fluorapatite (Ca5(PO4)3F)-wollastonite (CaSiO3) system are potential candidates for restorative dental and bone implant materials. The present study describes the influence of varying SiO2/CaO and CaF2/P2O5 molar ratio on the structure and thermal behavior of glass compositions in the CaO-MgO-SiO2-P2O5-Na2O-CaF2 system. The structural features and properties of the glasses were investigated by nuclear magnetic resonance (NMR), infrared spectroscopy, density measurements and dilatometry. Sintering and crystallization behavior of the glass powders were studied by hot-stage microscopy and differential thermal analysis, respectively. The microstructure and crystalline phase assemblage in the sintered glass powder compacts were studied under non-isothermal heating conditions at 825 °C. X-ray diffraction studies combined with the Rietveld-reference intensity ratio (R.I.R) method were employed to quantify the amount of amorphous and crystalline phases in the glass-ceramics, while scanning electron microscopy was used to shed some light on the microstructure of resultant glass-ceramics. An increase in CaO/SiO2 ratio degraded the sinterability of the glass powder compacts, resulting in the formation of akermanite as the major crystalline phase. On the other hand, an increase in P2O5/CaF2 ratio improved the sintering behavior of the glass-ceramics, while varying the amount of crystalline phases, i.e. diopside, fluorapatite and wollastonite.

    AIM: To compare the outcomes of a cohort of Crohn’s disease(CD) patients undergoing early surgery(ES) to those undergoing initial medical therapy(IMT).METHODS: We performed a review of a prospective database CD patients managed at a single tertiary institution. Inclusion criteria were all patients with ileal or ileocolonic CD between 1995-2014. Patients with incomplete data, isolated colonic or perianal CD were excluded. Primary endpoints included the need for, and time to subsequent surgery. Secondary endpoints included the number and duration of hospital admissions, and medical therapy. RESULTS: Forty-two patients underwent ES and 115 underwent IMT. The operative intervention rate at 5 years in the ES group was 14.2% vs IMT 31.3%(HR = 0.41, 95%CI: 0.23-0.72, P = 0.041). The ES group had fewer hospital admissions per patient [median 1 vs 3(P = 0.012)] and fewer patients required anti-TNF therapy than IMT(33.3% vs 57%, P = 0.003). A subgroup analysis of 62 IMT patients who had undergone surgery were compared to ES patients, and showed similar 5 year(from index surgery) re-operation rates 16.1% vs 14.3%. In this subset, a significant difference was still found in median number of hospital admissions favouring ES, 1 vs 2(P = 0.002).CONCLUSION: Our data supports other recent studies suggesting that patients with ileocolonic CD may have a more benign disease course if undergoing early surgical intervention, with fewer admissions to hospital and atrend to reduced overall operation rates.

    This study evaluates whether a sedentary lifestyle is an independent predictor for increased mortality after elective cardiac surgery. Three thousand one hundred fifty patients undergoing elective cardiac surgery between January 2007 and June 2012 completed preoperatively the Corpus Christi Heart Project questionnaire concerning physical activity (PA). Based on this questionnaire, 1815 patients were classified as active and 1335 patients were classified as sedentary. The endpoints of the study were hospital mortality and early mortality. The study population had a mean age of 69.7 ± 10.1 (19-95) years and a mean logistic EuroSCORE risk of 5.1 ± 5.6 (0.88-73.8). Sedentary patients were significantly older (p = 0.001), obese (p = 0.001), had a higher EuroSCORE risk (p = 0.001), and a higher percentage of complications. Hospital mortality (1.1 % versus 0.4 % (p = 0.014)) and early mortality (1.5 % versus 0.6 % (p = 0.006)) were significantly higher in the sedentary group compared with the active group. However, a sedentary lifestyle was not identified as an independent predictor for hospital mortality (p = 0.61) or early mortality (p = 0.70). Sedentary patients were older, obese and had a higher EuroSCORE risk. They had significantly more postoperative complications, higher hospital mortality and early mortality. Despite these results, sedentary behaviour could not be identified as an independent predictor for hospital or early mortality.

    Persistent acetabular dysplasia is a common reason for the failure of hip arthroscopic surgery; however, the effect of prior hip arthroscopic surgery on functional outcomes after subsequent periacetabular osteotomy (PAO) is unknown. Hypothesis/Purpose: The purpose of this study was to (1) compare demographic and radiological findings in patients who had and had not undergone previous hip arthroscopic surgery before PAO for symptomatic acetabular dysplasia and (2) compare the short-term, hip-specific patient-reported outcomes in these same patient populations. It was hypothesized that prior hip arthroscopic surgery is associated with worse early functional outcomes in PAO. Cohort study; Level of evidence, 3. A retrospective cohort study design was utilized. Patients undergoing PAO were enrolled from a single-center, prospective hip preservation registry from March 2011 to April 2015. Patients with a minimum of 1-year clinical follow-up with preoperative and postoperative outcome scores undergoing PAO were eligible for inclusion (n = 93 patients; mean clinical follow-up, 24 months [range, 11-58 months]). The study group consisted of patients undergoing PAO for symptomatic hip dysplasia after prior hip arthroscopic surgery (PREVSCOPE group; 22 patients, 25 hips). Patients undergoing PAO without prior hip arthroscopic surgery (PAOALONE group; 71 patients, 85 hips) were included as a comparison group. Demographic and radiological variables were recorded. Postoperative functional outcome scores (modified Harris Hip Score [mHHS], Hip Outcome Score [HOS], and International Hip Outcome Tool [iHOT-33]) were recorded at 6 months and annually postoperatively. There were no demographic differences between the 2 groups at baseline. Acetabular version, femoral version, Tönnis grade, preoperative lateral center edge angle, and intraoperative procedures were not different between the 2 groups. At 1-year follow-up from the last hip surgical procedure, the mean (±SD) mHHS (73 ± 14

    Full Text Available Roux-en-Y gastric bypass (RYGB is an effective method to attain sustained weight loss and diabetes remission. We aimed to elucidate early changes in the plasma metabolome and lipidome after RYGB. Plasma samples from 16 insulin-resistant morbidly obese subjects, of whom 14 had diabetes, were subjected to global metabolomics and lipidomics analysis at pre-surgery and 4 and 42 days after RYGB. Metabolites and lipid species were compared between time points and between subjects who were in remission and not in remission from diabetes 2 years after surgery. We found that the variables that were most discriminatory between time points were decanoic acid and octanoic acid, which were elevated 42 days after surgery, and sphingomyelins (18:1/21:0 and 18:1/23:3, which were at their lowest level 42 days after surgery. Insulin levels were lower at 4 and 42 days after surgery compared with pre-surgery levels. At 4 days after surgery, insulin levels correlated positively with metabolites of branched chain and aromatic amino acid metabolism and negatively with triglycerides with long-chain fatty acids. Of the 14 subjects with diabetes prior to surgery, 7 were in remission 2 years after surgery. The subjects in remission displayed higher pre-surgery levels of tricarboxylic acid cycle intermediates and triglycerides with long-chain fatty acids compared with subjects not in remission. Thus, metabolic alterations are induced soon after surgery and subjects with diabetes remission differ in the metabolic profiles at pre- and early post-surgery time points compared to patients not in remission.

  11. Professor Peter Choyce: an early pioneer of intraocular lenses and corneal/refractive surgery.

    Professor Peter Choyce, FRCS, DOMS, MS, was one of the pioneers of intraocular lens implant surgery. He developed an interest in artificial lens implantation following cataract surgery, a procedure that was widely criticized by the ophthalmic establishment in the UK, Europe, North America and other countries. Owing to the opposition to the intraocular lenses, Peter Choyce together with Sir Harold Ridley co-founded the International Intraocular Implant Club in 1966, which was responsible for the gradual acceptance of artificial lens implantation. Peter Choyce developed several models of intraocular lens, but did not patent the majority of them. The Choyce Mark IX, manufactured by Rayner Intraocular Lenses, became the first US Food and Drug Administration-approved intraocular lens in 1981. A review of Peter Choyce's record confirms a significant number of original innovations in the field of anterior segment surgery, including many procedures taken for granted today, but not associated with his name. These include early work on both kerato- and intraocular lens-refractive procedures, keratoprosthesis, pioneering paediatric implant procedures and others. Unfortunately his tenacious adherence to anterior chamber lens technology, while in general clinically sound, caused many to question his influence and hence he remained poorly understood even until after his death. He passed away on 8 August 2001 after a long fight with colon cancer. In this article, we provide evidence and elaborate Peter Choyce's accomplishments, which places him as one of the most innovative ophthalmologist in his surgical field in the twentieth century.

    We investigate the impact of the residual kidney volume measured by tumor volumetry on preoperative imaging in predicting post-operative renal function. Nephron sparing surgery (NSS) in renal cell carcinoma (RCC) is the standard treatment for T1 kidney tumors. Resection of kidney tumors in solidary kidneys needs precise preoperative counseling of patients regarding post-operative renal function. Patients planned for renal tumor surgery who underwent prior nephrectomy on the contralateral side were included. We identified 35 patients in our database that underwent NSS in solitary kidneys and met the inclusion criteria. Tumor volumetry was performed on computer tomography (CT) or magnetic resonance imaging (MRI) with the Medical Imaging Interaction Toolkit (MITK). Clinical and pathological data were assessed. Follow-up data included renal function over 3 years. Mean age was 64 ± 8.1 years. Mean tumor volume on imaging was 27.5 ± 48.6 cc. Mean kidney volume was 195.2 ± 62.8 cc and mean residual kidney volume was 173.4 ± 65.3 cc. We found a correlation between renal function (MDRD) and residual kidney volume on imaging 1-week post-surgery (p = 0.038). Mid- and long-term renal function was not associated with residual kidney volume. In conclusion, renal volumetry may predict early renal function after NSS.

    Full Text Available To assess the ability of the urinary biomarkers IGFBP7 (insulin-like growth factor-binding protein 7 and TIMP-2 (tissue inhibitor of metalloproteinase 2 to early predict acute kidney injury (AKI in high-risk surgical patients.Postoperative AKI is associated with an increase in short and long-term mortality. Using IGFBP7 and TIMP-2 for early detection of cellular kidney injury, thus allowing the early initiation of renal protection measures, may represent a new concept of evaluating renal function.In this prospective study, urinary [TIMP-2]×[IGFBP7] was measured in surgical patients at high risk for AKI. A predefined cut-off value of [TIMP-2]×[IGFBP7] >0.3 was used for assessing diagnostic accuracy. Perioperative characteristics were evaluated, and ROC analyses as well as logistic regression models of risk assessment were calculated with and without a [TIMP-2]×[IGFBP7] test.107 patients were included in the study, of whom 45 (42% developed AKI. The highest median values of biomarker were detected in septic, transplant and patients after hepatic surgery (1.24 vs 0.45 vs 0.47 ng/l²/1000. The area under receiving operating characteristic curve (AUC for the risk of any AKI was 0.85, for early use of RRT 0.83 and for 28-day mortality 0.77. In a multivariable model with established perioperative risk factors, the [TIMP-2]×[IGFBP7] test was the strongest predictor of AKI and significantly improved the risk assessment (p<0.001.Urinary [TIMP-2]×[IGFBP7] test sufficiently detect patients with risk of AKI after major non-cardiac surgery. Due to its rapid responsiveness it extends the time frame for intervention to prevent development of AKI.

  15. Recurrent sigmoid volvulus - early resection may obviate later emergency surgery and reduce morbidity and mortality.

    LENUS (Irish Health Repository)

    Larkin, J O

    2012-01-31

    INTRODUCTION: Acute sigmoid volvulus is a well recognised cause of acute large bowel obstruction. PATIENTS AND METHODS: We reviewed our unit\\'s experience with non-operative and operative management of this condition. A total of 27 patients were treated for acute sigmoid volvulus between 1996 and 2006. In total, there were 62 separate hospital admissions. RESULTS: Eleven patients were managed with colonoscopic decompression alone. The overall mortality rate for non-operative management was 36.4% (4 of 11 patients). Fifteen patients had operative management (five semi-elective following decompression, 10 emergency). There was no mortality in the semi-elective cohort and one in the emergency surgery group. The overall mortality for surgery was 6% (1 of 15). Five of the seven patients managed with colonoscopic decompression alone who survived were subsequently re-admitted with sigmoid volvulus (a 71.4% recurrence rate). The six deaths in our overall series each occurred in patients with established gangrene of the bowel. With early surgical intervention before the onset of gangrene, however, good outcomes may be achieved, even in patients apparently unsuitable for elective surgery. Eight of the 15 operatively managed patients were considered to be ASA (American Society of Anesthesiologists) grade 4. There was no postoperative mortality in this group. CONCLUSIONS: Given the high rate of recurrence of sigmoid volvulus after initial successful non-operative management and the attendant risks of mortality from gangrenous bowel developing with a subsequent volvulus, it is our contention that all patients should be considered for definitive surgery after initial colonoscopic decompression, irrespective of the ASA score.

    Full Text Available Aims and Objectives: To study wheather the facial features return to normal after surgery for muscular torticollis done in early childhood. Materials and Methods: This is a long-term study of the fate of facial asymmetry in four children who have undergone operation for muscular torticollis in early childhood. All the patients presented late, i.e., after the age of 4 years with a scarred sternomastoid and plagiocephaly, so conservative management with physiotherapy was not considered. All the patients had an x-ray of cervical spine and eye and dental checkup before making a diagnosis of muscular torticollis. Preoperative photograph of the patient′s face was taken to counsel the parents about the secondary effect of short sternomastoid on facial features and the need for surgery. After division of sternomastoid muscle and release of cervical fascia when indicated, the head was maintained in a hyperextended position supported by sand bags for three days. Gradual physiotherapy was then started followed by wearing of a Minerva collar that the child wore for a maximum period of time in 24 h. Physiotherapy was continued three times a day till the range of movements of the head returned to normal. During the follow-up, serial photographs were taken to note the changes in the facial features. Results: In all four patients, the asymmetry of the face got corrected and the facial features returned to normal. Conclusion: Most of the deformity of facial asymmetry gets corrected in the first two years after surgery. By adolescence, the face returns to normal.

    Laparoscopy has become the gold standard technique for appendectomy and cholecystectomy. With the emergence of newer laparoscopic instruments which are roticulating and provide 7 degrees of freedom it is now possible to perform these operations through a single umbilical incision rather than the standard 3-4 incisions and thus lead to more desirable cosmetic results and less postoperative pain. The newer reticulating telescopes provide excellent exposure of the operating field and allow the operations to proceed routinely. Recently, ports [Triports (Olympus surgery)/SILS ports] especially designed for single incision laparoscopic surgery (SILS) have been developed. We herein describe our experience with laparoscopic single port appendectomies and cholecystectomies in children using the Triport. This is a retrospective cohort study of children who underwent single incision laparoscopic surgery between May 2009 and August 2010 at Texas Children's Hospital and Ben Taub General Hospital in Houston Texas by a single surgeon. Charts were reviewed for demographics, type of procedure, operative time, early or late complications, outcome and cosmetic results. Fifty-four patients underwent SILS. A total of 50 appendectomies (early or perforated) and 4 cholecystectomies were performed using this new minimally invasive approach. The average operative time for SILS/LESS appendectomy was 54 min with a range between 25 and 205 min, while operative time for SILS cholecystectomy was 156 min with a range of 75-196 min. Only small percentage (4%) of appendectomies (mostly complicated) were converted to standard laparoscopy, but none were converted to open procedure. All patients were followed up in the clinic after 3-4 weeks. No complications were noted and all patients had excellent cosmetic results. Parents were extremely satisfied with the cosmetic results. SILS/LESS is a safe, minimally invasive approach for appendectomy and cholecystectomy in children. This new approach is

    To determine whether a collaborative learning strategy-derived clinical practice guideline can reduce the duration of endotracheal intubation following infant heart surgery. Prospective and retrospective data collected from the Pediatric Heart Network in the 12 months pre- and post-clinical practice guideline implementation at the four sites participating in the collaborative (active sites) compared with data from five Pediatric Heart Network centers not participating in collaborative learning (control sites). Ten children's hospitals. Data were collected for infants following two-index operations: 1) repair of isolated coarctation of the aorta (birth to 365 d) and 2) repair of tetralogy of Fallot (29-365 d). There were 240 subjects eligible for the clinical practice guideline at active sites and 259 subjects at control sites. Development and application of early extubation clinical practice guideline. After clinical practice guideline implementation, the rate of early extubation at active sites increased significantly from 11.7% to 66.9% (p collaborative learning strategy designed clinical practice guideline significantly increased the rate of early extubation with no change in the rate of reintubation. The early extubation clinical practice guideline did not significantly change postoperative ICU length of stay.

    Few reports have focused on treatment of adult cervical deformity (ACD). To present early complication rates associated with ACD surgery. A prospective multicenter database of consecutive operative ACD patients was reviewed for early (≤30 days from surgery) complications. Enrollment required at least 1 of the following: cervical kyphosis >10 degrees, cervical scoliosis >10 degrees, C2-7 sagittal vertical axis >4 cm, or chin-brow vertical angle >25 degrees. Seventy-eight patients underwent surgical treatment for ACD (mean age, 60.8 years). Surgical approaches included anterior-only (14%), posterior-only (49%), anterior-posterior (35%), and posterior-anterior-posterior (3%). Mean numbers of fused anterior and posterior vertebral levels were 4.7 and 9.4, respectively. A total of 52 early complications were reported, including 26 minor and 26 major. Twenty-two (28.2%) patients had at least 1 minor complication, and 19 (24.4%) had at least 1 major complication. Overall, 34 (43.6%) patients had at least 1 complication. The most common complications included dysphagia (11.5%), deep wound infection (6.4%), new C5 motor deficit (6.4%), and respiratory failure (5.1%). One (1.3%) mortality occurred. Early complication rates differed significantly by surgical approach: anterior-only (27.3%), posterior-only (68.4%), and anterior-posterior/posterior-anterior-posterior (79.3%) (P = .007). This report provides benchmark rates for overall and specific ACD surgery complications. Although the surgical approach(es) used were likely driven by the type and complexity of deformity, there were significantly higher complication rates associated with combined and posterior-only approaches compared with anterior-only approaches. These findings may prove useful in treatment planning, patient counseling, and ongoing efforts to improve safety of care. 3CO, 3-column osteotomiesACD, adult cervical deformityEBL, estimated blood lossISSG, International Spine Study groupSVA, sagittal vertical axis.

    Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations. The pathology study confirmed: pT3N0 (n = 7), pT3N1 (n = 3), pT3N2 (n = 1), and pT3N1M1 (n = 1), pT1N0 (n = 4), pT1N1 (n = 2), pTis (n = 1).

    Abstract Recently, a few studies have raised the question of whether preoperative chemoradiotherapy (PCRT) is essential for all T3 rectal cancers. This case-matched study aimed to compare the long-term outcomes of surgery alone with those of PCRT + surgery for magnetic resonance imaging (MRI)-assessed T3ab (extramural depth of invasion ≤5 mm) and absent mesorectal fascia invasion (clear MRF) in mid/lower rectal cancer patients. From January 2006 to November 2012, 203 patients who underwent curative surgery alone (n = 118) or PCRT + surgery (n = 85) were enrolled in this retrospective study. A 1:1 propensity score-matched analysis was performed to eliminate the inherent bias. Case-matching covariates included age, sex, body mass index, histologic grade, carcinoembryonic antigen, operation method, follow-up period, tumor height, and status of lymph node metastasis. The end-points were the 5-year local recurrence (LR) rate and disease-free-survival (DFS). After propensity score matching, 140 patients in 70 pairs were included. Neither the 5-year LR rate nor the DFS was significantly different between the 2 groups (the 5-year LR rate, P = 0.93; the 5-year DFS, P = 0.94). The 5-year LR rate of the surgery alone was 2% (95% confidence interval [CI] 0.2%–10.9%) versus 2% (95% CI 0.2%–10.1%) in the PCRT + surgery group. The 5-year DFS of the surgery alone was 87% (95% CI 74.6%–93.7%) versus 88% (95% CI 77.8%–93.9%) in the PCRT + surgery group. In patients with MRI-assessed T3ab and clear MRF mid/lower rectal cancer, the long-term outcomes of surgery alone were comparable with those of the PCRT + surgery. The suggested MRI-assessed T3ab and clear MRF can be used as a highly selective indication of surgery alone in mid/lower T3 rectal cancer. Additionally, in those patients, surgery alone can be tailored to the clinical situation. PMID:28328820

    Despite the lack of an official pronouncement, the fluorapatite of Cerro de Mercado, Durango, Mexico has become the de facto standard for (U-Th)/He geochronology. In addition to being relatively inclusion-free and easily obtained, these crystals are commonly in excess of 5mm in diameter, permitting the removal of the outer skin of the crystal, theoretically eliminating the alpha-ejection correction. However, bulk analyses of the Durango fluorapatite indicate a substantial variation in U and Th concentrations from aliquot to aliquot (167-238 ppm Th; 9.7-12.3 ppm U, [1]). If similar variations were to occur on the sub-grain scale, small fragments of single crystals could contain helium excesses or deficiencies due to alpha-ejection exchange between zones with varying parent element content. We have performed a series of experiments to quantify the intra-grain variation in U and Th, in order to model the effect of this variation on ages determined on Durango fluorapatite. X-ray maps show concentric zonation in U and Th, with similar, but more apparently pronounced zonation in Si and Cl. Preliminary laser-ablation ICPMS data indicate, not surprisingly, that intra-grain variations in U and Th concentrations obtained by analysis of ~35 μ m spots are larger than that which had been previously obtained by bulk analytical techniques (with overall concentrations greater than for bulk analyses). Thus far, analyses yield U concentrations varying from 11 to 16 ppm, and Th concentrations ranging from 220 to 340 ppm. Modeling underway suggests that parent element variations on the order of 50%, such as those observed, and the resulting differential alpha-exchange could lead to several percent error in age, for ~100 μ m fragments. The effect scales inversely with fragment size, with 300 μ m fragments (roughly the size of a large, single grain analysis) having only ~1% error. This may offer an explanation for the previously observed inability to reproduce ages for the Durango

    Full Text Available Abstract During the recent years improved operation techniques and administrative procedures have been developed for early rehabilitation. At the same time preoperative lifestyle intervention (prehabilitation has revealed a large potential for additional risk reduction. The aim was to assess the quality of life and to estimate the cost-effectiveness of standard care versus an integrated programme including prehabilitation and early rehabilitation. Methods The analyses were based on the results from 60 patients undergoing lumbar fusion for degenerative lumbar disease; 28 patients were randomised to the integrated programme and 32 to the standard care programme. Data on cost and health related quality of life was collected preoperatively, during hospitalisation and postoperatively. The cost was estimated from multiplication of the resource consumption and price per unit. Results Overall there was no difference in health related quality of life scores. The patients from the integrated programme obtained their postoperative milestones sooner, returned to work and soaked less primary care after discharge. The integrated programme was 1,625€ (direct costs 494€ + indirect costs 1,131€ less costly per patient compared to the standard care programme. Conclusion The integrated programme of prehabilitation and early rehabilitation in spine surgery is more cost-effective compared to standard care programme alone.

    Full Text Available Background: Active mobilization is a key component in fast-track surgical strategies. Following major surgery, clinicians are often reluctant to mobilize patients arguing that circulatory homeostasis would be impaired as a result of myocardial stunning, fluid shift, and autonomic dysfunction. Aims: We examined the feasibility and safety of a mobilization protocol 12-24 h after elective cardiac surgery. Setting and Design: This observational study was performed in a tertiary nonacademic cardiovascular Intensive Care Unit. Materials and Methods: Over a 6-month period, we prospectively evaluated the hemodynamic response to a two-staged mobilization procedure in 53 consecutive patients. Before, during, and after the mobilization, hemodynamics parameters were recorded, including the central venous oxygen saturation (ScvO 2 , lactate concentrations, mean arterial pressure (MAP, heart rate (HR, right atrial pressure (RAP, and arterial oxygen saturation (SpO 2 . Any adverse events were documented. Results: All patients successfully completed the mobilization procedure. Compared with the supine position, mobilization induced significant increases in arterial lactate (34.6% [31.6%, 47.6%], P = 0.0022 along with reduction in RAP (−33% [−21%, −45%], P 10% and nine of them (17% required treatment. Hypotensive patients experienced a greater decrease in ScvO 2 (−18 ± 5% vs. −9 ± 4%, P = 0.004 with similar changes in RAP and HR. All hemodynamic parameters, but arterial lactate, recovered baseline values after resuming the horizontal position. Conclusions: Early mobilization after cardiac surgery appears to be a safe procedure as far as it is performed under close hemodynamic and clinical monitoring in an intensive care setting.

    Full Text Available Context: Subclinical keratoconus is contraindication to refractive surgery. The currently used methods of preoperative screening do not always allow differentiating between healthy eyes and those with subclinical keratoconus. Aim: To evaluate biomechanical parameters of the cornea, waveform score (WS, and intraocular pressure (IOP as potentially useful adjuncts to the diagnostic algorithm for precise detection of the early keratoconus stages and selection of refractive surgery candidates. Settings and Design: Department of Ophthalmology and prospective cross-sectional study. Patients and Methods: Patients enrolled in the study were diagnosed with refractive disorders. We assessed parameters of corneal biomechanics such as corneal hysteresis (CH, corneal resistance factor (CRF, Goldman-correlated IOP (IOPg, corneal compensated IOP, WS, and keratoconus match index (KMI. They were classified into one of three groups based on the predefined KMI range: Group 1 (from 0.352 to 0.757 – 45 eyes, Group 2 (from −0.08 to 0.313 – 52 eyes, and Group 0 - control group (from 0.761 to 1.642 – 80 eyes. Results: In both study groups, IOPg, CRF, and CH were decreased when compared to control (P < 0.0001. In control group, there was positive correlation between CH and KMI (P < 0.05, with no correlations in any of the two study groups. CRF correlated positively with KMI in control (P < 0.0001 and in Group 2 (P < 0.05. Conclusions: CH and CRF, together with WS and IOPg, consist a clinically useful adjunct to detect subclinical keratoconus in patients referred for refractive surgery when based on KMI staging.

    To investigate the efficacy of thrombomodulin (TM)-α for treatment of disseminated intravascular coagulopathy (DIC) in the field of gastrointestinal surgery. Thirty-six peri-operative DIC patients in the field of gastrointestinal surgery who were treated with TM-α were retrospectively investigated. The relationships between patient demographics and the efficacy of TM-α were examined. Analysis of survival at 28 d was also performed on some parameters by means of the Kaplan-Meier method. Relationships between the initiation of TM-α and patient demographics were also evaluated. Abscess formation or bacteremia was the most frequent cause of DIC (33%), followed by digestive tract perforation (31%). Twenty-six patients developed DIC after surgery, frequently within 1 wk (81%). TM-α was most often administered within 1 d of the DIC diagnosis (72%) and was continued for more than 3 d (64%). Although bleeding tendency was observed in 7 patients (19%), a hemostatic procedure was not needed. DIC scores, systemic inflammatory response syndrome (SIRS) scores, quick-sequential organ failure assessment (qSOFA) scores, platelet counts, and prothrombin time ratios significantly improved after 1 wk (P SIRS and qSOFA) at 1 wk were significantly better prognostic factors for 28-d survival (P < 0.05, for all). TM-α was administered significantly earlier to patients with severe clinical symptoms, such as high qSOFA scores, sepsis, shock or high lactate values (P < 0.05, for all). Early administration of TM-α and improvements in each parameter were essential for treatment of DIC. The diagnosis of patients with mild symptoms requires further study.

    Mechanical properties of alumina-fluorapatite composites with different titania additive amounts (0, 0.5, 1, 1.4, 2, 3, 4 and 5 wt%) have been investigated between 1200 and 1600℃. The optimum values of densification and mechanical properties of composites have been reached with 1.4 wt% of titania after the sintering process at 1500℃ for 1 h. Thus, the rupture strength of alumina-26.52 wt% Fap-1.4 wt% TiO2 reaches 75 MPa. At higher temperature and beyond 1.4 wt% TiO2 ,the densification and mechanical properties were hindered by the formation of both intergranular porosity and secondary phase. X-ray diffraction (XRD) analysis of alumina-Fap-TiO2 composites shows the formation of aluminium titanate (Al2O3-TiO2:Al2TiO5 ). The 27Al magic angle scanning nuclear magnetic resonance analysis of Al2O3-Fap-TiO2 composites reveals the presence of octahedral and pentahedral aluminium and novel environment relative to tetrahedral aluminium sites.

    The synthesis of nanostructured fluorapatite (FA; Ca10(PO4 )6F2 ) was explored from the starting materials of CaHPO4,Ca(OH)2,CaO,P2Os and CaF2 via a mechanochemical process.In this research,the suitability of using the mechanochemical process to prepare a high crystalline phase of FA was studied.The characterization and structural features of the synthesized powders were evaluated using powder X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR),energy dispersive X-ray spectroscopy (EDX),scanning electron microscopy (SEM),and transmission electron microscopy (TEM) techniques.The results from the structural studies indicate that the maximum lattice disturbance in the apatite structure after the mechanochemical process was at the (0 0 2) plane.Furthermore,the maximum particle size was below the crystallite size after 60 h of milling and subsequent thermal treatment at 600 ℃ for 1 h (heated up to 600℃ and kept for 1 h at this temperature).We determined that this method gives rise to the single-crystal FA with an average size in the range of 25 ± 5 to 29 ± 9 nm.The present findings suggest that the solid-state reaction and appropriate thermal process simultaneously lead to the formation of nanostructured FA with spheroidal shape.

    As colorectal cancer and colorectal liver metastases become a serious public health problem, new treatment modalities are needed in order to achieve better results. In the last decade there has been very important progress in oncology, with new and more effective chemotherapeutic agents administered alone or in combination improving the resectability rate in up to 40% of patients with colorectal liver metastases. Advances in interventional radiology, in particular, with the use of portal vein embolization and radiofrequency thermal ablation are new strategies allowing major liver resections and treatment of small liver metastases or early recurrences. Surgery, however, remains the gold standard strategy with intention to treat. In this review article we will describe the advanced role of surgery in the multidisciplinary approach to colorectal liver metastases, and the clinical problems the liver surgeon has to deal with, such as the resectability of the metastases, the presence of bilobar liver lesions and extrahepatic disease, the impact of chemotherapy in already resectable liver metastases, the problem of vanishing metastases after chemotherapy and the dilemma of staged or combined liver and colon operations and which organ first in the clinical scenario of synchronous colorectal liver metastases.

  12. Early Functional Treatment and Modern Cast Making for Indications in Hand Surgery

    Full Text Available Cast treatment can serve both as a nonsurgical treatment option and as a means for providing postoperative protection. However, with the duration of immobilization intervals, the benefits of cast treatment, especially in hand surgery, are at risk of being outweighed by undesired drawbacks such as joint stiffening and contracture formation. In order to minimize potential complications commonly associated with cast treatment, efforts to further improve cast making must attempt to reconcile two conflicting objectives: (1 to achieve stability and rigidity at the site of injury (e.g., fracture retention and (2 to allow free range of joint movement as early as possible. In addition, in order to assure patient compliance, modern cast treatments should aim to improve wearing-comfort of the cast. This paper describes modern cast designs for four common types hand injuries, with sample cases highlighting the clinical outcome of each treatment.

    Full Text Available Early goal-directed therapy is a term used to describe the guidance of intravenous fluid and vasopressor/inotropic therapy by using cardiac output or similar parameters in the immediate post-cardiopulmonary bypass in cardiac surgery patients. Early recognition and therapy during this period may result in better outcome. In keeping with this aim in the cardiac surgery patients, we conducted the present study. The study included 30 patients of both sexes, with EuroSCORE ≥3 undergoing coronary artery bypass surgery under cardiopulmonary bypass. The patients were randomly divided into two groups, namely, control and early goal-directed therapy (EGDT groups. All the subjects received standardized care; arterial pressure was monitored through radial artery, central venous pressure through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour and frequent arterial blood gas analysis. In addition, cardiac index monitoring using FloTrac™ and continuous central venous oxygen saturation using PreSep™ was used in patients in the EGTD group. Our aim was to maintain the cardiac index at 2.5-4.2 l/min/m 2 , stroke volume index 30-65 ml/beat/m 2 , systemic vascular resistance index 1500-2500 dynes/s/cm 5 /m 2 , oxygen delivery index 450-600 ml/min/m 2 , continuous central venous oximetry more than 70%, stroke volume variation less than 10%; in addition to the control group parameters such as central venous pressure 6-8 mmHg, mean arterial pressure 90-105 mmHg, normal arterial blood gas analysis values, pulse oximetry, hematocrit value above 30% and urine output more than 1 ml/kg/h. The aims were achieved by altering the administration of intravenous fluids and doses of inotropic or vasodilator agents. Three patients were excluded from the study and the data of 27 patients analyzed. The extra volume used (330 ± 160 v/s 80 ± 80 ml, P = 0.043 number of adjustments of inotropic agents (3

    Obesity is associated with respiratory symptoms that are reported to improve with weight loss, but this is poorly reflected in spirometry, and few studies have measured respiratory mechanics with oscillometry. We investigated whether early changes in lung mechanics following weight loss are detectable with oscillometry. Furthermore, we investigated whether the changes in lung mechanics measured in the supine position following weight loss are associated with changes in sleep quality. Nineteen severely obese female subjects (mean body mass index, 47.2 ± 6.6 kg/m(2)) were evaluated using spirometry, oscillometry, plethysmography, and the Pittsburgh Sleep Quality Index before and 5 weeks after bariatric surgery. These tests were conducted in both the upright and the supine position, and pre- and postbronchodilation with 200 μg of salbutamol. Five weeks after surgery, weight loss of 11.5 ± 2.5 kg was not associated with changes in spirometry and plethysmography, with the exception of functional residual capacity. There were also no changes in upright respiratory system resistance (Rrs) or reactance following weight loss. Importantly, however, in the supine position, weight loss caused a substantial reduction in Rrs. In addition, sleep quality improved significantly and was highly correlated with the reduction in supine Rrs. Prior to weight loss, subjects did not respond to the bronchodilator when assessed in the upright position with either spirometry or oscillometry; however, with modest weight loss, bronchodilator responsiveness returned to the normal range. Improvements in lung mechanics occur very early after weight loss, mostly in the supine position, resulting in improved sleep quality. These improvements are detectable with oscillometry but not with spirometry.

    This study sought to demonstrate that early cardiac catheterization, whether used solely as a diagnostic modality or for the use of transcatheter interventional techniques, can be used effectively and with an acceptable risk in the post-operative period. Cardiac catheterization offers important treatment for patients with congenital heart disease. Early post-operative cardiac catheterization is often necessary to diagnose and treat residual anatomic defects. Experience with interventional catheterization to address post-operative concerns is limited. This was a retrospective cohort study. The medical and catheterization data of pediatric patients who underwent a cardiac catheterization ≤30 days after congenital heart surgery between November 2004 and July 2013 were reviewed. Patients who underwent right heart catheterization and endomyocardial biopsy after heart transplantation were excluded. A total of 219 catheterizations (91 interventional procedures, 128 noninterventional catheterizations) were performed on 193 patients. Sixty-five interventions (71.43%) were dilations, either balloon angioplasty or stent implantation. There was no difference in survival to hospital discharge between those who underwent an interventional versus noninterventional catheterization (p = 0.93). One-year post-operative survival was comparable between those who underwent an intervention (66%) versus diagnostic (71%) catheterization (p = 0.58). There was no difference in the incidence of major or minor complications between the interventional and diagnostic catheterization cohorts (p = 0.21). Cardiac catheterization, including transcatheter interventions, can be performed safely in the immediate post-operative period after congenital heart surgery.

    The incidence and causes that may lead to an early end (unfinished cortical/subcortical mapping) of awake surgery for language mapping are little known. A study was conducted on 41 patients with brain glioma located in the language area that had awake surgery under conscious sedation. Surgery was ended early in 6 patients. The causes were: tonic-clonic seizure (1), lack of cooperation due to fatigue/sleep (4), whether or not word articulation was involved, a decreased level of consciousness for ammonia encephalopathy that required endotracheal intubation (1). There are causes that could be expected and in some cases avoided. Tumour size, preoperative aphasia, valproate treatment, and type of anaesthesia used are variables to consider to avoid failure in awake surgery for language mapping. With these results, the following measures are proposed: l) If the tumour is large, perform surgery in two times to avoid fatigue, 2) if patient has a preoperative aphasia, do not use sedation during surgery to ensure that sleepiness does not cause worse word articulation, 3) if the patient is on valproate treatment, it is necessary to rule out the pre-operative symptoms that are not due to ammonia encephalopathy.

    Cerebral cavernous malformations (CCM) can cause intracerebral hemorrhage. The lesions themselves are frequently associated with perifocal hemosiderin deposits caused by repetitive microhemorrhages. Main indications for a surgical treatment are recurrent symptomatic hemorrhages or cavernoma-related epilepsy. After surgical resection, follow-up magnetic resonance imaging (MRI) is usually performed to confirm 1) the complete resection of the CCM and, especially in cases of cavernoma-related epilepsy, 2) the complete resection of the hemosiderin deposits. This prospective study evaluates the value of early postoperative MRI (within 72 hours) regarding the detection of CCM or hemosiderin remnants compared with a standard 3-6 months postoperative MRI control in 61 CCM cases. Sensitivity of early postoperative MRI for CCM remnant detection was 66.67% (95% confidence interval [CI], 9.43%-99.16%), specificity was 76.74% (95% CI, 61.37%-88.24%), positive predictive value was 16.67% (95% CI, 2.09%-48.41%), and negative predictive value was 97.06% (95% CI, 84.67%-99.93%). Because of the high number of patients who could not be evaluated because of imaging artifacts, sensitivity and specificity analysis was not performed for early postoperative MRI using T2*/susceptibility-weighted imaging to assess hemosiderin remnants. Sensitivity of early postoperative MRI for hemosiderin remnant detection using T2-weighted sequences was 85.71% (95% CI, 63.66%-96.95%), specificity was 66.67% (95% CI, 44.68%-84.37%), positive predictive value was 69.23% (95% CI, 55.45%-80.27%), and negative predictive value was 84.21% (95% CI, 64.31%-94.04%). Our data suggest that early postoperative MRI after CCM surgery is often hampered by imaging artifacts creating false-positive results and therefore ineligible for a resection control. However, reliability of a negative result on early postoperative T2-weighted MRI is relatively high regarding both CCM and hemosiderin remnants. Copyright © 2017

    Objective To retrospectively analyze and compare conservative versus surgical treatment of patients with fulminant acute pancreatitis (FAP) plus abdominal compartment syndrome (ACS). Methods From January 1998 to September 2005, 21 patients with FAP plus ACS were retrospectively analyzed. Ten patients were conservatively treated by means of intensive care medicine without surgery, and 11 patients received open surgical management and suction drainage. Results Seven of the 10 non-surgical patients died, comprising one with mild, four with moderate and two with severe ACS (70% mortality rate). Of the 11 patients receiving open surgical management in the early phase (within 3 days of disease initiation), three died, comprising one with moderate and two with severe ACS (27.3% mortality rate). The difference in mortality rates was found to be statistically significant. Conclusion Our data indicate patients suffering FAP with severe ACS should be treated with open management of the abdomen in the early phase (within 3 days), even in the absence of infection. This approach appears superior to that of conservative management. Surgical treatment resulted in abdominal decompression and subsequently significantly decreased the mortality rate and improved overall prognosis.

    Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

    The early and late results of bypass surgery in 124 patients with unresectable oesophageal cancer are reported. Patients were grouped according to the extent of disease: group A, tumour localized to the oesophagus where severe pulmonary disease contra-indicated oesophagectomy (n = 9); group B, tumour less than or equal to 10 cm in length with mediastinal invasion (n = 81); group C, tumour greater than 10 cm in length with mediastinal invasion and/or fixed malignant lymph nodes (n = 33). Extent of disease was not recorded in one patient. The operative mortality was 4 per cent but 9 other patients died in hospital (hospital mortality, 11 per cent). Mortality was increased in patients undergoing colon bypass and in those with a large tumour load but these differences failed to reach statistical significance. The most frequent complication was neck sepsis, secondary to leakage from the proximal end of the excluded oesophagus. Eighty-nine per cent of the survivors could eat a normal, unrestricted diet on discharge and eighty-two per cent of survivors had complete and lasting relief from dysphagia. Median survival after bypass was 5 months but survival was significantly improved by radiotherapy to the tumour (P less than 0.001). Gastric bypass with radiotherapy is indicated in patients with extra-oesophageal spread of malignancy and in patients with tumours localized to the oesophagus who are unfit for resection. Bypass surgery may be contra-indicated in patients with a primary tumour greater than 10 cm in length and/or fixed lymph node metastases because mortality is increased and survival after operation is short.

    Full Text Available Background: The impact of early mobilization on perioperative comorbidities and length of stay (LOS has shown benefits in other medical/surgical subspecialties. However, few spinal series have specifically focused on the "pros" of early mobilization for spinal surgery, other than in acute spinal cord injury. Here we reviewed how early mobilization and other adjunctive measures reduced morbidity and LOS in both medical and/or surgical series, and focused on how their treatment strategies could be applied to spinal patients. Methods: We reviewed studies citing protocols for early mobilization of hospitalized patients (day of surgery, first postoperative day/other in various subspecialties, and correlated these with patients′ perioperative morbidity and LOS. As anticipated, multiple comorbid factors (e.g. hypertension, high cholesterol, diabetes, hypothyroidism, obesity/elevated body mass index hypothyroidism, osteoporosis, chronic obstructive pulmonary disease, coronary artery disease and other factors contribute to the risks and complications of immobilization for any medical/surgical patient, including those undergoing spinal procedures. Some studies additionally offered useful suggestions specific for spinal patients, including prehabilitation (e.g. rehabilitation that starts prior to surgery, preoperative and postoperative high protein supplements/drinks, better preoperative pain control, and early tracheostomy, while others cited more generalized recommendations. Results: In many studies, early mobilization protocols reduced the rate of complications/morbidity (e.g. respiratory decompensation/pneumonias, deep venous thrombosis/pulmonary embolism, urinary tract infections, sepsis or infection, along with the average LOS. Conclusions: A review of multiple medical/surgical protocols promoting early mobilization of hospitalized patients including those undergoing spinal surgery reduced morbidity and LOS.

    In order to understand the contribution of geogenic phosphorus to lake eutrophication, we have investigated the rate and extent of fluorapatite dissolution in the presence of two common soil bacteria ( Pantoea agglomerans and Bacillus megaterium) at T = 25 °C for 26 days. The release of calcium (Ca), phosphorus (P), and rare earth elements (REE) under biotic and abiotic conditions was compared to investigate the effect of microorganism on apatite dissolution. The release of Ca and P was enhanced under the influence of bacteria. Apatite dissolution rates obtained from solution Ca concentration in the biotic reactors increased above error compared with abiotic controls. Chemical analysis of biomass showed that bacteria scavenged Ca, P, and REE during their growth, which lowered their fluid concentrations, leading to apparent lower release rates. The temporal evolution of pH in the reactors reflected the balance of apatite weathering, solution reactions, bacterial metabolism, and potentially secondary precipitation, which was implied in the variety of REE patterns in the biotic and abiotic reactors. Light rare earth elements (LREE) were preferentially adsorbed to cell surfaces, whereas heavy rare earth elements (HREE) were retained in the fluid phase. Decoupling of LREE and HREE could possibly be due to preferential release of HREE from apatite or selective secondary precipitation of LREE enriched phosphates, especially in the presence of bacteria. When corrected for intracellular concentrations, both biotic reactors showed high P and REE release compared with the abiotic control. We speculate that lack of this correction explains the conflicting findings about the role of bacteria in mineral weathering rates. The observation that bacteria enhance the release rates of P and REE from apatite could account for some of the phosphorus burden and metal pollution in aquatic environments.

    This study was performed to evaluate the disease-free survival and risk factors of recurrence in early breast cancer patients who have undergone breast conserving surgery and radiation therapy. Materials and Methods: From March 1997 to December 2002, 77 breast cancer patients who underwent breast conserving surgery and radiation therapy were reviewed retrospectively. The median follow-up time was 58.4 months (range 43.8-129.4 months) and the mean subject age was 41 years. The frequency distribution of the different T stages, based on the tumor characteristics was 38 (49.3%) for T1, 28 (36.3%) for T2, 3 for T3, 7 for Tis and 1 for an unidentified sized tumor. In addition, 52 patients (67.5%) did not have axillary lymph metastasis, whereas 14 patients (18.1%) had 1-3 lymph node metastases and 3 (0.03%) had more than 4 lymph node metastases. The resection margin was negative in 59 patients, close ({<=}2 mm) in 15, and positive in 4. All patients received radiation therapy at the intact breast using tangential fields with a subsequent electron beam boost to the tumor bed at a total dose ranging from 59.4 Gy to 66.4 Gy. Patients with more than four positive axillary lymph nodes received radiation therapy (41.4-60.4 Gy) at the axillary and supraclavicular area. Chemotherapy was administered in 59 patients and tamoxifen or fareston was administered in 29 patients. Results: The 5 year overall survival and disease-free survival rates were 98.08% and 93.49%, respectively. Of the 77 patients, a total of 4 relapses (5.2%), including 1 isolated supraclavicular relapse, 1 supraclavicular relapse with synchronous multiple distant relapses, and 2 distant relapses were observed. No cases of local breast relapses were observed. Lymph node metastasis or number of metastatic lymph nodes was not found to be statistically related with a relapse (p=0.3289) nor disease-free survival (p=0.1430). Patients with positive margins had a significantly shorter disease-free survival period (p<0

    Intraparenchymal hemorrhages occur in a proportion of severe traumatic brain injury TBI patients, but the role of surgery in their treatment is unclear. This international multi-center, patient-randomized, parallel-group trial compared early surgery (hematoma evacuation within 12 h of randomization) with initial conservative treatment (subsequent evacuation allowed if deemed necessary). Patients were randomized using an independent randomization service within 48 h of TBI. Patients were eligible if they had no more than two intraparenchymal hemorrhages of 10 mL or more and did not have an extradural or subdural hematoma that required surgery. The primary outcome measure was the traditional dichotomous split of the Glasgow Outcome Scale obtained by postal questionnaires sent directly to patients at 6 months. The trial was halted early by the UK funding agency (NIHR HTA) for failure to recruit sufficient patients from the UK (trial registration: ISRCTN19321911). A total of 170 patients were randomized from 31 of 59 registered centers worldwide. Of 82 patients randomized to early surgery with complete follow-up, 30 (37%) had an unfavorable outcome. Of 85 patients randomized to initial conservative treatment with complete follow-up, 40 (47%) had an unfavorable outcome (odds ratio, 0.65; 95% confidence interval, CI 0.35, 1.21; p=0.17), with an absolute benefit of 10.5% (CI, -4.4-25.3%). There were significantly more deaths in the first 6 months in the initial conservative treatment group (33% vs. 15%; p=0.006). The 10.5% absolute benefit with early surgery was consistent with the initial power calculation. However, with the low sample size resulting from the premature termination, we cannot exclude the possibility that this could be a chance finding. A further trial is required urgently to assess whether this encouraging signal can be confirmed.

  13. Anatomic Total Talar Prosthesis Replacement Surgery and Ankle Arthroplasty: An Early Case Series in Thailand

    2014-01-01

    Little is known about specific outcomes and early experiences of total talar prosthesis replacement surgery in the current literature, and ankle arthroplasty in Southeast Asia. This study reported on four patients with talar loss or ankle arthritis. Patients were treated with a custom total talar prosthesis (anatomic-metallic version) replacement (TPR, n=1) or with total ankle replacement (TAR, n=3). Baseline data, including Visual-Analog-Scale Foot and Ankle (VAS-FA) and Quality of Life scores via Short-Form-36 (SF-36), were collected for all patients. Mean follow-up time was 7.6 months. From preoperative to postoperative, VAS-FA score increased from 6.0 to 57.5, and SF-36 score increased from 19.3 to 73.7 in a patient with TPR. Mean VAS-FA scores increased from 51.5±15.6 to 85.7±4.7 (P=0.032), and mean SF-36 scores tended to increase from 65.2±13.3 to 99.3±1.2 (P=0.055) in TAR group. This study is the first report of anatomic-metallic TPR which appears to provide satisfactory outcomes for treatment of talar loss at a short-term follow-up. TAR also provides acceptable results for treatment of ankle arthritis at this point. PMID:25317313

    Full Text Available Background. Features that may allow early identification of patients at risk of prolonged delirium, and therefore of poorer outcomes, are not well understood. The aim of this study was to determine if preoperative delirium risk factors and delirium symptoms (at onset and clinical symptomatology during the course of delirium are associated with delirium duration. Methods. This study was conducted in prospectively identified cases of incident delirium. We compared patients experiencing delirium of short duration (1 or 2 days with patients who had more prolonged delirium (≥3 days with regard to DRS-R-98 (Delirium Rating Scale Revised-98 symptoms on the first delirious day. Delirium symptom profile was evaluated daily during the delirium course. Results. In a homogenous population of 51 elderly hip-surgery patients, we found that the severity of individual delirium symptoms on the first day of delirium was not associated with duration of delirium. Preexisting cognitive decline was associated with prolonged delirium. Longitudinal analysis using the generalised estimating equations method (GEE identified that more severe impairment of long-term memory across the whole delirium episode was associated with longer duration of delirium. Conclusion. Preexisting cognitive decline rather than severity of individual delirium symptoms at onset is strongly associated with delirium duration.

    Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ≥66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients.

    Stability relations of monazite-fluorapatite-allanite and xenotime-(Y,HREE)-rich fluorapatite-(Y,HREE)-rich epidote are strongly dependent on pressure, temperature and fluid composition. The increased Ca bulk content expands stability field of allanite relative to monazite towards higher temperatures (Spear, 2010, Chem Geol 279, 55-62). It was also reported from amphibolite facies Alpine metapelites, that both temperature and bulk CaO/Na2O ratio control relative stabilities of allanite, monazite and xenotime (Janots et al., 2008, J Metam Geol 26, 5, 509-526). This study experimentally defines influence of pressure, temperature, high activity of Ca vs. Na in the fluid, and high vs. moderate bulk CaO/Na2O ratio on the relative stabilities of monazite-fluorapatite-allanite/REE-rich epidote and xenotime-(Y,HREE)-rich fluorapatite-(Y,HREE)-rich epidote. This work expands previous experimental study on monazite (Budzyń et al., 2011, Am Min 96, 1547-1567) to wide pressure-temperature range of 2-10 kbar and 450-750°C, utilizing most reactive fluids used in previous experiments. Experiments were performed using cold-seal autoclaves on a hydrothermal line (2-4 kbar runs) and piston-cylinder apparatus (6-10 kbar runs) over 4-16 days. Four sets of experiments, two for monazite and two for xenotime, were performed with 2M Ca(OH)2 and Na2Si2O5 + H2O fluids. The starting materials included inclusion-free crystals of monazite (pegmatite, Burnet County, TX, USA) or xenotime (pegmatite, Northwest Frontier Province, Pakistan) mixed with (1) labradorite (Ab37An60Kfs3) + K-feldspar + biotite + muscovite ± garnet + SiO2 + CaF2 + 2M Ca(OH)2 or (2) albite (Ab100) + K-feldspar + biotite + muscovite ± garnet + SiO2 + CaF2 + Na2Si2O5 + H2O. 20-35 mg of solids and 5 mg of fluid were loaded into 3x15 mm Au capsules and arc welded shut. The monazite alteration is observed in all runs. Newly formed REE-rich fluorapatite and/or britholite are stable in all experimental P-T range in the

    Full Text Available Background : Post-operative cognitive dysfunction is the subtle cerebral complication temporally seen following surgery. The aim of this study was to compare the influence of either general anesthesia (GA or epidural anesthesia (EA on the early post-operative neurocognitive outcome in elderly (>59 years subjects undergoing hip and knee surgery. Methods : A total of 60 patients were recruited in a prospective, randomized, parallel-group study, comparable by age and sex. They were enrolled and randomized to receive either EA (n = 30 or GA (n = 30. All of them were screened using the Mini Mental State Examination (MMSE, with components of the Kolkata Cognitive Screening Battery. The operated patients were re-evaluated 1 week after surgery using the same scale. The data collected were analyzed to assess statistical significance. Results : We observed no statistical difference in cognitive behavior in either group pre-operatively, which were comparable with respect to age, sex and type of surgery. Grossly, a significant difference was seen between the two groups with respect to the perioperative changes in verbal fluency for categories and MMSE scores. However, these differences were not significant after the application of the Bonferroni correction for multiple analyses, except the significant differences observed only in the MMSE scores. Conclusions : We observed a difference in cognitive outcome with GA compared with EA. Certain aspects of the cognition were affected to a greater extent in this group of patients undergoing hip and knee surgery.

    Full Text Available Six baby’s with cleft are born in Indonesia every hour. There is no standardized treatment of cleft in East Indonesia. Closure is an important aspect during cleft lip and palate surgery. Various techniques have been advocated to gain tissue for closure of cleft area. Mostly these techniques may only provide a small amount of additional length. For lager defects they may be use the local flaps or the buccal fat pad flap. The aim of this study is gain more information about intraoperative and early postoperative complications using the buccal fat pat during cleft palate surgery in East Indonesia. The mouth can be divided in six parts therefor the LAHSAL index will be used. This LAHSAL system is a diagrammatic classification of cleft lip and palate. The LAHSAL system is being used for this study as this system classifies the cleft primarily on location and also on the cleft being complete or incomplete, which can be significant for the research. After diagnosis and classification, the following patient data was obtained: patient age, weight, gender, type of surgery (primary or following, i.e. when the surgery is a correction of a previous treatment, if a bone graft is needed for closure, history of maxillofacial surgery or orthodontics, operation technique, operation duration, type of an aesthesia (local or general, radiographical records and light photos. These data were collected during the pre-operative consultation, about 24 hours before surgery. It was the policy of the team to admit and see all patients one day prior to surgery for counselling, postoperative instructions and evaluating the patient's facial defect.

    Full Text Available Clinical case of high thin-wall cystic limited filtering bleb needling revision in the early post-op period after trabeculectomy with sinusotomy accompanied by toxic keratopathy is presented. Optical coherence tomography (OCT demonstrated that filtering bleb height was 2700 μm and bleb wall thickness was 70 μm. Bleb needling revision with its lateralwall dissection and subconjunctival injection of dexamethasone, fluorouracil, and ranibizumab near to the bleb site was performed. In 1.5 hours after the procedure, bleb height decreased to 550 μm (by 5 times while bleb wall thickness increased up to 100 μm. Topical antibacterial, steroid, and non-steroid anti-inflammatory therapy was recommended. The next day IOP level reduced from 11 mm Hg to 4.5 mm Hg. It was accompanied by choroidal effusion that was managed conservatively with cycloplegic agents (drops and injections for 3 days. On day 6, central corneal edema affecting all layers, Descemet’s membrane folds, and ocular hypertension were revealed. Metabolic therapy resolved corneal edema within 3 days. Re-needling bleb revision decreased IOP level to 6.2 mm Hg. This resulted in transient Descemet’s membrane folds. This paper describes filtering bleb needling revision with its lateral wall dissection and anti-inflammatory, cytostatic, and anti-VEGF agents use to prolong glaucoma filtering surgery effect in excessive scarring. The procedure was accompanied by toxic corneal endothelium decompensation with corneal edema and Descemet’s membrane folds treated with active metabolic therapy.

    Recurrent gallstone ileus is an uncommon mechanical intestinal obstruction secondary to occlusion of the intestine by an intraluminal biliary calculus. Female, 75 years old, ischaemic heart disease (stent), arrived in our department complaining of abdominal pain and vomiting. Computed tomography showed gallstone ileus. The patient underwent an enterotomy with gallstone removal. Three months later, the patient came back with the same clinical symptoms and signs. A new computed tomography highlighted a gallstone ileus again. Enterolithotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient had a prolonged hospital stay due to the development of congestive heart failure. Case 2. Male, 71 years old, ischaemic heart disease and aortocoronary bypass, seen in our department complaining of vomiting. Computed tomography showed aerobilia and gallstone ileus. The patient underwent an urgent enterolithotomy. Seven months later, the patient came back with the same clinical symptoms and signs. Computed tomography showed a new gallstone ileus. An enterotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient died due to multi-organ failure in post-surgery period. In the elderly patients with concomitant medical illnesses with the risk of a second laparotomy, it is justifiable to reconsider the definitive repair in the treatment of gallstone ileus. The enterolithotomy in acute phase followed by early cholecystectomy (4-8 weeks) may be a safe method for eliminating, not only the possibility of recurrent gallstone ileus, and probably the need for a second laparotomy, but also the exceptional possibility of developing a gallbladder carcinoma.

    Full Text Available Minimally invasive techniques in cardiac surgery gained popularity due to many advantages like less postoperative pain, minimal blood loss, less hospital stay, less cost. Minimally invasive mitral valve surgery through right anterolateral mini thoracotomy became safe technique. In our study we compared mini-MV surgery with conventional technique regarding cross clamp time, bypass time, total blood loss, reopening for bleeding, and hospital and ICU length of stay. In our institution between 2010 and 2015, 147patients underwent minimally invasive mitral surgery through right lateral minithoracotomy 8 cm incision and 118 patient underwent conventional mitral valve surgery through median sternotomy in minimally invasive technique: mean age was 38 ± 20 vs 59 ± 21, 70.7% were female (n = 104 vs 39.8% (n = 47, 23.8% were associated with tricuspid valve regurgitation (n = 33 vs 55% in conventional technique (n = 65, 0.08% were able to use endovascular clamp (n = 12, mean Euroscore predected risk of mortality 14.7 ± 13.6% vs 8.7 ± 10.9%. Minimally invasive mitral valve repair surgery was accomplished in 77.5% (n = 114 vs 46.15% (n = 55 and replacement of mitral valve in 22.4% (n = 30 vs 53.8% (n = 64 , concomitant procedures consists of tricuspid valve surgery in 23.8% (n = 35 vs 55% (n = 65, primary mitral valve repair included implantation of rigid annuloplasty ring in 79.6% vs 38.9% (n = 46, duration of cardiopulmonary bypass in minimally invasive surgery was 123 ± 64 min vs 116 ± 62 min, cross clamp time was 64 ± 27 min vs 59 ± 23 min, postoperative mechanical ventilation time 4 ± 1.5 h vs 6.5 ± 2 h, ICU lenght of stay (LOS was 48 ± 12 h vs 3 ± 1 days. Minimally invasive mitral surgery can be performed very safely with excellent early results. mini-MV surgery can be performed with a reasonable operative time, good perioperative course with decrease in postoperative ICU and hospital

    The aim of this study is to determine whether surgery offers protection against early subtalar arthrodesis in displaced intraarticular calcaneal fractures. Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014. The modified Jadad scale was used for trial quality and effective data were pooled for meta-analysis. Study results related to early subtalar arthrodesis were extracted and risk assessment was combined with surgical treatment and nonsurgical treatment. The primary analysis included 4 studies and 966 participants. The estimated overall risk ratio was 4.40 (95% confidence interval 2.67-7.39), indicating the incidence of early subtalar arthrodesis in nonsurgical group is 4.4 times the surgical group. The results showed that surgical treatment was superior to nonsurgical treatment in protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures (Z = 5.600, P < 0.001).Surgery offers protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures.

    Early wound healing after periodontal surgery with or without enamel matrix derivative/biphasic calcium phosphate (EMD/BCP) was characterized in terms of soft tissue closure, changes of microcirculation, and expression of pro- and anti-inflammatory cytokines in gingival crevicular fluid/wound fluid (GCF/WF). Periodontal surgery was carried out in 30 patients (18 patients: application of EMD/BCP for regeneration of bony defects; 12 patients: surgical crown lengthening (SCL)). Healthy sites were observed as untreated controls. GCF/WF samples were collected during two post-surgical weeks. Flap microcirculation was measured using laser Doppler flowmetry (LDF). Soft tissue healing was evaluated after two weeks. GCF/WF levels of interleukin 1β (IL-1β), tumour necrosis factor (TNF-α), IL-6, and IL-10 were determined using a multiplex immunoassay. Surgery caused similar reductions of flap microcirculation followed by recovery within two weeks in both EMD/BCP and SCL groups. GCF/WF and pro-inflammatory cytokine levels were immediately increased after surgery, and returned only partially to baseline levels within the two-week observation period. Levels of IL-10 were temporarily reduced in all surgical sites. Flap dehiscence caused prolonged elevated levels of GCF/WF, IL-1β, and TNF-α. These findings show that periodontal surgery triggers an immediate inflammatory reaction corresponding to the early inflammatory phase of wound healing, and these inflammation measures are temporary in case of maintained closure of the flap. However, flap dehiscence causes prolonged inflammatory exudation from the periodontal wound. If the biological pre-conditions for periodontal wound healing are considered important for the clinical outcome, care should be taken to maintain primary closure of the flap. PMID:28134829

    Differences in postoperative outcome and recovery between patients subjected to laparoscopic-assisted versus open surgery for colorectal cancer (CRC) resection have been widely documented, though not specifically for right-sided tumors. We investigated the immunological responses to the different surgical approaches, by comparing postoperative data simultaneously obtained at systemic, local and cellular levels. A total of 25 right-sided CRC patients and controls were managed, assessing -in the immediate followup- the conventional perioperative parameters and a large panel of cytokines on plasma, peritoneal fluids and lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMC) tissue cultures. A general better recovery for patients operated with laparoscopy compared to conventional procedure, as indicated by the analysis of typical pre- and post-surgical parameters, was observed. The synchronous evaluation of 12 cytokines showed that preoperative plasma levels of the proinflammatory cytokines IL-6, IL-8, IL-1β, TNFα were significantly lower in healthy donors versus CRC patients and that such differences progressively increase with tumor stage. After surgery, the IL-6 and IL-8 increases were significantly higher in open compared to laparoscopic approach only in CRC at early stages. The postsurgical whole panel of cytokine levels were significantly higher in peritoneal fluids compared to corresponding plasma, but with no significant differences depending on kind of surgery or stage of disease. Then we observed that, pre- compared to the corresponding post-surgery derived LPS-stimulated PBMC cultures, produced higher supernatant levels of the whole cytokine panel. In particular IL-6 in vitro production was significantly higher in PBMC derived from patients subjected to laparoscopic versus open intervention, but -again- only in CRC at early stages of disease. Our results thus show that laparoscopy compared to open right resection is associated with a

    Patients who undergo major surgery for cancer are at high risk of postoperative sepsis. Early markers of septic complications would be useful for diagnosis and therapeutic management in patients with postoperative sepsis. The aim of this study was to investigate the association between early (first postoperative day) changes in interleukin 6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) serum concentrations and the occurrence of subsequent septic complications after major surgery. Serial blood samples were collected from 50 consecutive patients for determination of IL-6, PCT and CRP serum levels. Blood samples were obtained on the morning of surgery and on the morning of the first postoperative day. Sixteen patients developed septic complications during the first five postoperative days (group 1), and 34 patients developed no septic complications (group 2). On day 1, PCT and IL-6 levels were significantly higher in group 1 (P-values of 0.003 and 0.006, respectively) but CRP levels were similar. An IL-6 cut-off point set at 310 pg ml(-1) yielded a sensitivity of 90% and a specificity of 58% to differentiate group 1 patients from group 2 patients. When associated with the occurrence of SIRS on day 1 these values reached 100% and 79%, respectively. A PCT cut-off point set at 1.1 ng ml(-1) yielded a sensitivity of 81% and a specificity of 72%. When associated with the occurrence of SIRS on day 1, these values reached 100% and 86%, respectively. PCT and IL-6 appear to be early markers of subsequent postoperative sepsis in patients undergoing major surgery for cancer. These findings could allow identification of postoperative septic complications.

    There are no approved Food and Drug Administration indications for pediatric auditory brainstem implant (ABI) surgery in the United States. Our prospective case series aims to determine the safety and feasibility of ABI surgery in pediatric patients age, 2.52 ± 0.39 years). Four patients underwent ABI surgery (age, 19.2 ± 3.43 months), including 4 primary procedures and 1 revision for device failure. Spontaneous device failure occurred in another subject postoperatively. No major/minor complications occurred, including cerebrospinal fluid leak, facial nerve injury, hematoma, and nonauditory stimulation. All subjects detected sound with environmental awareness, and several demonstrated babbling and mimicry. Poor durability of older implants underscores need for updated technology. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Background: This study was aimed at investigating clinical and histopathologic features of ipsilateral breast tumor recurrences (IBTR) and their effects on survival after breast conservation therapy. Methods: 1,400 patients who were treated between 1998 and 2007 and had breast-conserving surgery (BCS) for early breast cancer (cT1-2/N0-1/M0) were evaluated. Demographic and pathologic parameters, radiologic data, treatment, and follow-up related features of the patients were recorded. Results: 53 patients (3.8%) had IBTR after BCS within a median follow-up of 70 months. The mean age was 45.7 years (range, 27-87 years), and 22 patients (41.5%) were younger than 40 years. 33 patients (62.3%) had true recurrence (TR) and 20 were classified as new primary (NP). The median time to recurrence was shorter in TR group than in NP group (37.0 (6-216) and 47.5 (11-192) months respectively; p = 0.338). Progesterone receptor positivity was significantly higher in the NP group (p = 0.005). The overall 5-year survival rate in the NP group (95.0%) was significantly higher than that of the TR group (74.7%, p 20 mm), high grade tumor and triple-negative molecular phenotype along with developing TR negatively affected overall survival (hazard ratios were 4.2 (CI 0.98-22.76), 4.6 (CI 1.07-13.03), 4.0 (CI 0.68-46.10), 6.5 (CI 0.03-0.68), and 6.5 (CI 0.02- 0.80) respectively, p 2 cm), high grade, triple negative phenotype, and having true recurrence were identified as independent prognostic factors with a negative impact on overall survival in this dataset of patients with recurrent breast cancer. In conjunction with a more intensive follow-up program, the role of adjuvant therapy strategies should be explored further in young patients with large and high-risk tumors to reduce the risk of TR.

    In April 2010, the Department of Health introduced the hip fracture best practice. Among the clinical criteria required to earn remuneration is surgery within 36 h of admission. However, early surgery may mean that methicillin-resistant Staphylococcus aureus (MRSA) colonisation status is not known before surgery, and therefore, appropriate antibiotic prophylaxis may not be administered. In view of this, our department's policy is to administer an additional dose of teicoplanin to patients with unknown MRSA status along with routine antimicrobial prophylaxis. The purpose of this study was to provide a safe and effective antimicrobial prophylaxis for hip fracture patients. We prospectively collected details of demographics and antimicrobial prophylaxis for all patients admitted with a hip fracture in November 2011. This was repeated in February 2012 after an educational and advertising drive to improve compliance with departmental antimicrobial policy. Microbiology results were obtained from the hospital microbiology database. A cost-benefit analysis was undertaken to assess this regime. A total of 144 hip fracture patients were admitted during the 2 months. The average admission to surgery time was 32 h, and the average MRSA swab processing time was 35 h. 86 % of patients reached theatre with unknown MRSA status. Compliance with the departmental antimicrobial policy improved from 25 % in November 2011 to 76 % in February 2012. Potential savings of £ 40,000 were calculated. With best practice tariff resulting in 86 % of patients reaching theatre with unknown MRSA status, we advocate an additional single dose of teicoplanin to cover against possible MRSA colonisation.

    Full Text Available Introduction. Endocrine therapy (ET is an integral part of breast cancer (BC treatment with surgical resection remaining the cornerstone of curative treatment. The objective of this study is to compare the survival of elderly postmenopausal women with hormone receptor-positive early-stage BC treated with ET alone, without radiation or chemotherapy, versus ET plus surgery. Materials and Methods. This is a retrospective study based on a prospective database. The medical records of postmenopausal BC patients referred to the surgical oncology service of two hospitals during an 8-year period were reviewed. All patients were to receive ET for a minimum of four months before undergoing any surgery. Results. Fifty-one patients were included and divided in two groups, ET alone and ET plus surgery. At last follow-up in exclusive ET patients (n=28, 39% had stable disease or complete response, 22% had progressive disease, of which 18% died of breast cancer, and 39% died of other causes. In surgical patients (n=23, 78% were disease-free, 9% died of recurrent breast cancer, and 13% died of other causes. Conclusions. These results suggest that surgical resection is beneficial in this group and should be considered, even for patients previously deemed ineligible for surgery.

    An empirical calibration with a natural mineral standard (fluorapatite from Cerro de Mercado, Mexico) is proposed as a method to determine the {sup 4}He concentration of mineral and rock samples. The procedure is based on the fusion of several aliquots of the fluorapatite standard with a well-spaced weight distribution in order to obtain a good correlation in coordinates of {sup 4}He peak height versus fluorapatite weight. The weight is then converted to moles using the accepted mineral age (31.4 Ma) and appropriate formula. Experimental peak height of {sup 4}He for the unknown samples are converted to moles with the regression determined for fluorapatite. The procedure is fast and inexpensive, and both precision and accuracy are always below 10% and usually about 3-5%.

    Full Text Available Objective: To evaluate the postoperative outcome after using combined lumbar and sacral plexus block (CLSB, as a sole anesthetic method in hip fracture (HF surgery in highrisk geriatric patients. Materials and Methods: A single-center retrospective study was conducted, between 2010 and 2012, on 70 elderly HF patients with American Society of Anesthesiologists grading III-IV who underwent early surgical intervention with our CLSB protocol. Perioperative data, outcome, and complications were recorded. Results: Forty-eight patients (69% had ongoing anticoagulant medication. Postoperatively, all patients were hemodynamically stable and awake. None of them required general anesthesia conversion. Minor anesthetic-related complications were found in nine patients. One patient (1% died from sepsis due to pneumonia. Patients’ satisfactions were all rated as very good or excellent. Conclusion: CLSB is an interesting anesthetic option in HF surgery, especially in high surgical risk geriatric patients. This method offers an excellent clinical efficiency and high patients’ satisfaction without serious complications.

    OBJECTIVE To study the local recurrence and the role of whole breast radiotherapy for early breast cancer treated by conservative surgery.METHODS From April 1990 to December 2000, 49 patients with early primary breast cancer were treated by conservative surgery in our hospital. The cases were comprised of Stage 0, 1; Stage Ⅰ, 31; and Stage Ⅱa,17. Forty cases underwent quadrantectomy plus axillary lymph node dissection, and the other 9 cases had lumpectomy alone. Irradiation, which was received by 39 patients, was administered by using low tangential half fields with 6 MV X-ray to decrease the pulmonary irradiative volume.The dose to the whole breast was 45 Gy/22~23f/4.5W, then a 15 Gy boost dose was delivered to the tumor bed by an electron beam. The other patients underwent an irradiated regional field according to postoperative pathology.RESULTS All patients were followed-up for 10 years or more. The 10year local recurrence rates, distant metastasis rates and survival rates were 6.1%, 4.1% and 98.0% respectively. All of the 3 patients who had a local recurrence had infiltrative carcinomas and negative lymph nodes.The 10-year local recurrence rate was higher (2.6% vs. 20.0%) with nonpostoperative whole breast radiotherapy, but the statistical difference was not marked because of the low number of cases. All of the recurrent lesions localized within 3 cm of the primary lesion.CONCLUSION Original recurrence of the tumor was the main type of local recurrence. Radiotherapy after conservative surgery is very essential.After conservative surgery it is feasible that irradiation can be delivered alone to the neighboring region of the tumor bed. Partial breast radiotherapy can substitute for whole breast radiotherapy.

    To study innate immune pathways in patients undergoing hepatopancreaticobiliary surgery to understand mechanisms leading to enhanced inflammatory responses and identifying biomarkers of adverse clinical consequences. Patients undergoing major abdominal surgery are at risk of life-threatening systemic inflammatory response syndrome (SIRS) and sepsis. Early identification of at-risk patients would allow tailored postoperative care and improve survival. Two separate cohorts of patients undergoing major hepatopancreaticobiliary surgery were studied (combined n = 69). Bloods were taken preoperatively, on day 1 and day 2 postoperatively. Peripheral blood mononuclear cells and serum were separated and immune phenotype and function assessed ex vivo. Early innate immune dysfunction was evident in 12 patients who subsequently developed SIRS (postoperative day 6) compared with 27 who did not, when no clinical evidence of SIRS was apparent (preoperatively or days 1 and 2). Serum interleukin (IL)-6 concentration and monocyte Toll-like receptor (TLR)/NF-κB/IL-6 functional pathways were significantly upregulated and overactive in patients who developed SIRS (P SIRS. Increased TLR4 and TLR5 gene expression in whole blood was demonstrated in a separate validation cohort of 30 patients undergoing similar surgery. Expression of TLR4/5 on monocytes, particularly intermediate CD14CD16 monocytes, on day 1 or 2 predicted SIRS with accuracy 0.89 to 1.0 (areas under receiver operator curves). These data demonstrate the mechanism for IL-6 overproduction in patients who develop postoperative SIRS and identify markers that predict patients at risk of SIRS 5 days before the onset of clinical signs.

    This study aimed to explore whether echocardiographic measurements during the early postoperative period can predict persistent left ventricular systolic dysfunction (LVSD) after aortic valve surgery in patients with chronic aortic regurgitation (AR). We prospectively recruited 54 patients (59 ± 12 years) with isolated chronic severe AR who subsequently underwent aortic valve surgery. Standard transthoracic echocardiography was performed before the operation, during the early postoperative period (≤2 weeks), and then 1 year after the surgery. Twelve patients with preoperative LVSD demonstrated LVSD at early after the surgery. Of the 42 patients without LVSD at preoperative echocardiography, 15 patients (36%) developed early postoperative LVSD after surgical correction. All 27 patients without LVSD at early postoperative echocardiography maintained LV function at 1 year after surgery. In the other 27 patients with postoperative LVSD, 17 patients recovered from LVSD and 10 patients did not at 1 year after surgery. Multiple logistic analysis demonstrated that postoperative left atrial volume index (LAVI) was the only independent predictor for persistent LVSD at 1 year after surgery in patients with postoperative LVSD (OR 1.180, 95% CI, 1.003-1.390, P = 0.046). The optimal LAVI cutoff value (>34.9 mL/m(2) ) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent LVSD. Prevalence of early postoperative LVSD was relatively high, even in the patients without LVSD at preoperative echocardiography. Postoperative LAVI could be useful to predict persistent LVSD after aortic valve surgery in patients with early postoperative LVSD. © 2014, Wiley Periodicals, Inc.

    From antiquity through the Renaissance, congenital blindness was generally regarded as incurable, as noted in both medical and lay publications. The earliest reference to congenital cataract surgery that we identified, reported in 1663, referred to an 18-year-old female treated by English oculist John Stepkins (d. 1652). An examination of the literature related to the Stepkins family reveals the presence of male and female oculists during that period, including his daughter, Lady Theodosia Ivy. Eye waters attributed to Stepkins contained tutty (an oxide of zinc), roses, sugar candy, and other ingredients. Interestingly, John Thomas Woolhouse, the author of the next identified report of congenital cataract surgery in 1706, stated that he was related to Stepkins. Woolhouse reported by 1721 that he had performed 36 congenital cataract surgeries, with the youngest patient being 18 months of age.

    Full Text Available Context : Pre- and postoperative distress in breast cancer patients can cause complications and delay recovery from surgery. Objective : The aim of our study was to evaluate the effects of yoga intervention on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery. Methods : Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited in a randomized controlled trial comparing the effects of a yoga program with supportive therapy and exercise rehabilitation on postoperative outcomes and wound healing following surgery. Subjects were assessed at the baseline prior to surgery and four weeks later. Sociodemographic, clinical and investigative notes were ascertained in the beginning of the study. Blood samples were collected for estimation of plasma cytokines-soluble Interleukin (IL-2 receptor (IL-2R, tumor necrosis factor (TNF-alpha and interferon (IFN-gamma. Postoperative outcomes such as the duration of hospital stay and drain retention, time of suture removal and postoperative complications were ascertained. We used independent samples t test and nonparametric Mann Whitney U tests to compare groups for postoperative outcomes and plasma cytokines. Regression analysis was done to determine predictors for postoperative outcomes. Results : Sixty-nine patients contributed data to the current analysis (yoga: n = 33, control: n = 36. The results suggest a significant decrease in the duration of hospital stay ( P = 0.003, days of drain retention ( P = 0.001 and days for suture removal ( P = 0.03 in the yoga group as compared to the controls. There was also a significant decrease in plasma TNF alpha levels following surgery in the yoga group ( P < 0.001, as compared to the controls. Regression analysis on postoperative outcomes showed that the yoga intervention affected the duration of drain retention and hospital stay as well as TNF alpha levels. Conclusion : The results suggest

    Full Text Available Background: A leakage of intestinal anastomosis is typically regarded as a devastating post-operative complication. Traditionally its believed that long fasting after intestinal surgery protect anastomosis site and most surgeons applied this method. Post-operative long fasting has many physical and mental adverse effects, especially in children, but its benefit has not proven yet. This study aimed to compare the outcomes of early and late oral feeding in intestinal resection and anastomosis surgery in children. Patients and Methods: This randomized, double-blind controlled trial evaluated the outcome of early-feeding following in children aged 1 month to 12 years who underwent intestinal resection and anastomosis and compared the results with those who had late-feeding. The results were anlysed for fever, nausea and vomiting, abdominal distension, first passage of gas and stool were also evaluated hospital stay time, major post-operative complications such as anastomosis leakage, wound infection or dehiscence, intra-abdominal abscess between the two groups. Results: The mean time of first oral feeding in the early feeding group (study group was 2.5 ± 0.7 days but it was 5.3 ± 0.6 days in the late feeding group (control group. There was no mortality in both groups. There was no difference in major complications in both groups (anastomosis leakage. In the study group, first defecation time was shorter than the control group (3.7 days v. 4.4 days and they had less hospital stay also (5.2 days vs. 8.3 days and lower cost of hospitalization. Conclusion: Early oral feeding after intestinal resection and anastomosis in children is a safe method, it has many benefits and does not increase the major or minor post-operative complications (anastomosis leakage long time fasting is not necessary and has not any beneficial effect and early feeding increases satisfaction of the parents and children, and reduce hospital stay and costs.

  8. Limitations of early serum creatinine variations for the assessment of kidney injury in neonates and infants with cardiac surgery.

    Directory of Open Access Journals (Sweden)

    Mirela Bojan

    Full Text Available BACKGROUND: Changes in kidney function, as assessed by early and even small variations in serum creatinine (ΔsCr, affect survival in adults following cardiac surgery but such associations have not been reported in infants. This raises the question of the adequate assessment of kidney function by early ΔsCr in infants undergoing cardiac surgery. METHODOLOGY: The ability of ΔsCr within 2 days of surgery to assess the severity of kidney injury, accounted for by the risk of 30-day mortality, was explored retrospectively in 1019 consecutive neonates and infants. Patients aged ≤ 10 days were analyzed separately because of the physiological improvement in glomerular filtration early after birth. The Kml algorithm, an implementation of k-means for longitudinal data, was used to describe creatinine kinetics, and the receiver operating characteristic and the reclassification methodology to assess discrimination and the predictive ability of the risk of death. RESULTS: Three clusters of ΔsCr were identified: in 50% of all patients creatinine decreased, in 41.4% it increased slightly, and in 8.6% it rose abruptly. Mortality rates were not significantly different between the first and second clusters, 1.6% [0.0-4.1] vs 5.9% [1.9-10.9], respectively, in patients aged ≤ 10 days, and 1.6% [0.5-3.0] vs 3.8% [1.9-6.0] in older ones. Mortality rates were significantly higher when creatinine rose abruptly, 30.3% [15.1-46.2] in patients aged ≤ 10 days, and 15.1% [5.9-25.5] in older ones. However, only 41.3% of all patients who died had an abrupt increase in creatinine. ΔsCr improved prediction in survivors, but not in patients who died, and did not improve discrimination over a clinical mortality model. CONCLUSIONS: The present results suggest that a postoperative decrease in creatinine represents the normal course in neonates and infants with cardiac surgery, and that early creatinine variations lack sensitivity for the assessment of the severity of

    Early oral nutrition (EON) has been shown to improve recovery of gastrointestinal function, length of stay and mortality after abdominal surgery; however, early oral nutrition often fails during the first week after surgery. Here, a multi-modal early oral nutrition program is introduced to promote recovery of gastrointestinal function and tolerance of oral nutrition. Consecutive patients scheduled for abdominal surgery were randomized to the multimodal EON group or a group receiving conventional care. The primary endpoint was the time of first defecation. The secondary endpoints were outcomes and the cost-effectiveness ratio in treating infectious complications. The rate of infectious-free patients was regarded as the index of effectiveness. One hundred seven patients were randomly assigned to groups. Baseline characteristics were similar for both groups. In intention-to-treat analysis, the success rate of oral nutrition during the first week after surgery in the multimodal EON group was 44 (83.0%) versus 31 (57.4%) in the conventional care group (P = 0.004). Time to first defecation, time to flatus, recovery time of bowel sounds, and prolonged postoperative ileus were all less in the multimodal EON group (P multi-modal early oral nutrition group (P multi-modal early oral nutrition program was an effective way to improve tolerance of oral nutrition during the first week after surgery, decrease the length of stay and improve cost-effectiveness after abdominal surgery.

    Büchler Markus W

    2007-10-01

    Full Text Available Abstract Background Acute cholecystitis occurs frequently in the elderly and in patients with gall stones. Most cases of severe or recurrent cholecystitis eventually require surgery, usually laparoscopic cholecystectomy in the Western World. It is unclear whether an initial, conservative approach with antibiotic and symptomatic therapy followed by delayed elective surgery would result in better morbidity and outcome than immediate surgery. At present, treatment is generally determined by whether the patient first sees a surgeon or a gastroenterologist. We wish to investigate whether both approaches are equivalent. The primary endpoint is the morbidity until day 75 after inclusion into the study. Design A multicenter, prospective, randomized non-blinded study to compare treatment outcome, complications and 75-day morbidity in patients with acute cholecystitis randomized to laparoscopic cholecystectomy within 24 hours of symptom onset or antibiotic treatment with moxifloxacin and subsequent elective cholecystectomy. For consistency in both arms moxifloxacin, a fluorquinolone with broad spectrum of activity and high bile concentration is used as antibiotic.

    Nutritional support is important to optimize treatment outcomes in colorectal cancer surgery. Using retrospective review of patients' medical records, we sought to identify the kinds of nutritional problems patients with colorectal cancer reported on their first visit to the surgeon to support those at risk of malnutrition. After reviewing data from the Patient-Generated Subjective Global Assessment of Nutritional Status, patients had a supportive counseling meeting about nutrition with a nurse. Of the 153 patients, 65% were diagnosed with colon cancer and 35% with rectal cancer. Eighteen percent of those with colon cancer were overweight, and 12% were obese. Of those with rectal cancer, 10% were overweight, and 7% were obese. Weight loss was reported by 18% of the patients with colon cancer and by 12% of the patients with rectal cancer. To identify the patients who need nutritional support before colorectal cancer surgery, it is important to first identify the patients' nutritional status. When the focus is on surgery, it is possible that these problems are not mentioned if no questions are asked. Nutritional assessment at the outpatient department makes it possible to use the time lapse between examination and surgery to improve the nutritional status.

    To assess the association of systemic inflammation and outcome after major abdominal surgery. Major abdominal surgery carries a high postoperative morbidity and mortality rate. Studies suggest that inflammation is associated with unfavorable outcome. Levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α and the systemic inflammatory response syndrome (SIRS) were assessed in 137 patients undergoing major abdominal surgery. Blood samples were drawn on days 0, 1, 3, and 7, and SIRS was scored during 48 hours after surgery. Primary outcome was a composite of mortality, pneumonia, sepsis, anastomotic dehiscence, wound infection, noncardiac respiratory failure, atrial fibrillation, congestive heart failure, myocardial infarction, and reoperation within 30 days of surgery. An IL-6 level more than 432 pg/mL on day 1 was associated with an increased risk of complications (adjusted odds ratio: 3.3; 95% confidence interval [CI]: 1.3-8.5) and a longer median length of hospital stay (7 vs 12 days, P < 0.001). As a single test, an IL-6 cut-off level of 432 pg/mL on day 1 yielded a specificity of 70% and a sensitivity of 64% for the prediction of complications (area under the curve: 0.67; 95% CI: 0.56-0.77). Levels of CRP started to discriminate from day 3 onward with a specificity of 87% and a sensitivity of 58% for a cut-off level of 203 mg/L (AUC: 0.73; 95% CI: 0.63-0.83). A high IL-6 level on day 1 is associated with postoperative complications. Levels of IL-6 help distinguish between patients at low and high risk for complications before changes in levels of CRP.

    After cesarean section surgery, routine pharmacologic methods of analgesia--opioids and benzodiazepines--may impair the immediate close contact of mother and neonate for their sedative and emetic effects. The aim of this study was to explore the effect of patient-selected music on postoperative pain, anxiety, opioid requirement, and hemodynamic profile. A total of 80 patients, American Society of Anesthesiologists (ASA) physical status I-II, scheduled to undergo general anesthesia and elective cesarean section surgery were enrolled. Patients were randomly allocated to receive 30 minutes of music or silence via headphones postoperatively. Pain and anxiety were measured with a visual analogue scale. Total postoperative morphine requirement as well as blood pressure and heart rate were recorded after the intervention period. Pain score and postoperative cumulative opioid consumption were significantly lower among patients in the music group (p 0.05). Postoperative use of patient-selected music in cesarean section surgery would alleviate the pain and reduce the need for other analgesics, thus improving the recovery and early contact of mothers with their children.

    To study the effect of titania (TiO2) addition on the surface microstructure and bioactivity of fluorapatite coatings, fluorapatite was mixed with TiO2 in 1:0.5 (FA + 0.5TiO2), 1:0.8 (FA + 0.8TiO2), and 1:1 (FA + TiO2) ratios (wt%) and clad on Ti-6Al-4V substrates using an Nd:YAG laser system. The experimental results show that the penetration depth of the weld decreases with increasing TiO2 content. Moreover, the subgrain structure of the coating layer changes from a fine cellular-like structure to a cellular-dendrite-like structure as the amount of TiO2 increases. Consequently, as the proportion of TiO2 decreases (increase in fluorapatite content), the Ca/P ratio of the coating layer also decreases. The immersion of specimens into simulated body fluid resulted in the formation of individual apatite. With a lower Ca/P ratio before immersion, the growth of the apatite was faster and then the coating layer provided a better bioactivity. X-ray diffraction analysis results show that prior to simulated body fluid immersion, the coating layer in all three specimens was composed mainly of fluorapatite, CaTiO3, and Al2O3 phases. Following simulated body fluid immersion, a peak corresponding to hydroxycarbonated apatite appeared after 2 days in the FA + 0.5TiO2 and FA + 0.8TiO2 specimens and after 7 days in the FA + TiO2 specimen. Overall, the results show that although the bioactivity of the coating layer tended to decrease with increasing TiO2 content, in accordance with the above-mentioned ratios, the bioactivity of all three specimens remained generally good.

  17. Clinical assessment of peripheral perfusion to predict postoperative complications after major abdominal surgery early: a prospective observational study in adults

    2014-01-01

    Introduction Altered peripheral perfusion is strongly associated with poor outcome in critically ill patients. We wanted to determine whether repeated assessments of peripheral perfusion during the days following surgery could help to early identify patients that are more likely to develop postoperative complications. Methods Haemodynamic measurements and peripheral perfusion parameters were collected one day prior to surgery, directly after surgery (D0) and on the first (D1), second (D2) and third (D3) postoperative days. Peripheral perfusion assessment consisted of capillary refill time (CRT), peripheral perfusion index (PPI) and forearm-to-fingertip skin temperature gradient (Tskin-diff). Generalized linear mixed models were used to predict severe complications within ten days after surgery based on Clavien-Dindo classification. Results We prospectively followed 137 consecutive patients, from among whom 111 were included in the analysis. Severe complications were observed in 19 patients (17.0%). Postoperatively, peripheral perfusion parameters were significantly altered in patients who subsequently developed severe complications compared to those who did not, and these parameters persisted over time. CRT was altered at D0, and PPI and Tskin-diff were altered on D1 and D2, respectively. Among the different peripheral perfusion parameters, the diagnostic accuracy in predicting severe postoperative complications was highest for CRT on D2 (area under the receiver operating characteristic curve = 0.91 (95% confidence interval (CI) = 0.83 to 0.92)) with a sensitivity of 0.79 (95% CI = 0.54 to 0.94) and a specificity of 0.93 (95% CI = 0.86 to 0.97). Generalized mixed-model analysis demonstrated that abnormal peripheral perfusion on D2 and D3 was an independent predictor of severe postoperative complications (D2 odds ratio (OR) = 8.4, 95% CI = 2.7 to 25.9; D2 OR = 6.4, 95% CI = 2.1 to 19.6). Conclusions In a group of patients assessed following major abdominal surgery

    Objective: Early laryngeal cancer is usually treated with either transoral laser surgery or radiation therapy. The quality of voice achieved with these treatments has not been compared in a randomized trial. Methods and Materials: Male patients with carcinoma limited to 1 mobile vocal cord (T1aN0M0) were randomly assigned to receive either laser surgery (n=32) or external beam radiation therapy (n=28). Surgery consisted of tumor excision with a CO{sub 2} laser with the patient under general anaesthesia. External beam radiation therapy to the larynx was delivered to a cumulative dose of 66 Gy in 2-Gy daily fractions over 6.5 weeks. Voice quality was assessed at baseline and 6 and 24 months after treatment. The main outcome measures were expert-rated voice quality on a grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, videolaryngostroboscopic findings, and the patients' self-rated voice quality and its impact on activities of daily living. Results: Overall voice quality between the groups was rated similar, but voice was more breathy and the glottal gap was wider in patients treated with laser surgery than in those who received radiation therapy. Patients treated with radiation therapy reported less hoarseness-related inconvenience in daily living 2 years after treatment. Three patients in each group had local cancer recurrence within 2 years from randomization. Conclusions: Radiation therapy may be the treatment of choice for patients whose requirements for voice quality are demanding. Overall voice quality was similar in both treatment groups, however, indicating a need for careful consideration of patient-related factors in the choice of a treatment option.

    Full Text Available OBJECTIVE: Anesthetic and operative interventions in neonates remain hazardous procedures, given the vulnerability of the patients in this pediatric population. The aim was to determine the preoperative and intraoperative factors associated with 30-day post-operative mortality and describe mortality outcomes following neonatal surgery under general anesthesia in our center. METHODS: Infants less than 28 days of age who underwent general anesthesia for surgery during an 11-year period (2000 - 2010 in our tertiary care pediatric center were retrospectively identified using the pediatric intensive care unit database. Multiple logistic regression was used to identify independent preoperative and intraoperative factors associated with 30-day post-operative mortality. RESULTS: Of the 437 infants in the study (median gestational age at birth 37 weeks, median birth weight 2,760 grams, 28 (6.4% patients died before hospital discharge. Of these, 22 patients died within the first post-operative month. Logistic regression analysis showed increased odds of 30-day post-operative mortality among patients who presented American Society of Anesthesiologists physical status (ASA score 3 or above (odds ratio 19.268; 95%CI 2.523 - 147.132 and surgery for necrotizing enterocolitis/gastrointestinal perforation (OR 5.291; 95%CI 1.962 - 14.266, compared to those who did not. CONCLUSION: The overall in-hospital mortality of 6.4% is within the prevalence reported for developed countries. Establishing ASA score 3 or above and necrotizing enterocolitis/gastrointestinal perforation as independent risk factors for early mortality in neonatal surgery may help clinicians to more adequately manage this high risk population.

    The latest generation Da Vinci(®) Xi™ Surgical System Robot released has not been evaluated to date in transoral surgery for head and neck cancers. We report here the 1-year results of a non-randomized phase II multicentric prospective trial aimed at assessing its feasibility and technical specificities. Our primary objective was to evaluate the feasibility of transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot. The secondary objective was to assess peroperative outcomes. Twenty-seven patients, mean age 62.7 years, were included between May 2015 and June 2016 with tumors affecting the following sites: oropharynx (n = 21), larynx (n = 4), hypopharynx (n = 1), parapharyngeal space (n = 1). Eighteen patients were included for primary treatment, three for a local recurrence, and six for cancer in a previously irradiated field. Three were reconstructed with a FAMM flap and 6 with a free ALT flap. The mean docking time was 12 min. "Chopsticking" of surgical instruments was very rare. During hospitalization following surgery, 3 patients experienced significant bleeding between day 8 and 9 that required surgical transoral hemostasis (n = 1) or endovascular embolization (n = 2). Transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot proved feasible with technological improvements compared to previous generation surgical system robots and with a similar postoperative course. Further technological progress is expected to be of significant benefit to the patients.

    To evaluate the efficacy of diode laser welding to close corneal wounds in penetrating keratoplasty (PKP) and cataract surgery in pediatric patients. Ophthalmology Department, Bambino Gesù Children's Hospital, Rome, Italy. Prospective observational study. Patients had surgery for congenital cataract (Group 1) or femtosecond laser-assisted PKP (Group 2). The surgery was followed by corneal wound closure using diode laser welding of the stroma. In Group 1, no standard suturing was used. In Group 2, the donor button was sutured onto the recipient using 8 single nylon sutures or a 10-0 nylon running suture (12 passages). Laser welding was then used as an adjunct to the traditional suturing procedure. Group 1 comprised 7 eyes (7 patients; mean age 8.1 years ± 5.3 [SD], range 1 to 15 years) and Group 2, 5 eyes (5 patients; mean age 10.6 ± 3.3 years, range 6 to 15 years). The adhesion of the laser-welded tissues was perfect; there were no collateral effects, and restoration of the treated tissues was optimum. Seidel testing showed no wound leakage during the follow-up. Postoperative astigmatism did not change significantly from the first day after cataract surgery and shifted moderately 3 months after PKP. Laser welding of corneal tissue appeared to be safe and effective in children for whom a sutureless surgical procedure is important to reduce the use of anesthesia for suture management, prevent endophthalmitis, and improve the antiamblyopic effect.

    Introduction There are 11 500 rectal cancers diagnosed annually in the UK. Although surgery remains the primary treatment, there is evidence that preoperative radiotherapy (RT) improves local recurrence rates. High-quality surgery in rectal cancer is equally important in minimising local recurrence. Advances in MRI-guided prediction of resection margin status and improvements in abdominoperineal excision of the rectum (APER) technique supports a reassessment of the contribution of preoperative RT. A more selective approach to RT may be appropriate given the associated toxicity. Methods and analysis This trial will explore the feasibility of a definitive trial evaluating the omission of RT in resectable low rectal cancer requiring APER. It will test the feasibility of randomising patients to (1) standard care (neoadjuvant long course RT±chemotherapy and APER, or (2) APER surgery alone for cT2/T3ab N0/1 low rectal cancer with clear predicted resection margins on MRI. RT schedule will be 45 Gy over 5 weeks as current standard, with restaging and surgery after 8–12 weeks. Recruitment will be for 24 months with a minimum 12-month follow-up. Objectives Objectives include testing the ability to recruit, consent and retain patients, to quantify the number of patients eligible for a definitive trial and to test feasibility of outcomes measures. These include locoregional recurrence rates, distance to circumferential resection margin, toxicity and surgical complications including perineal wound healing, quality of life and economic analysis. The quality of MRI staging, RT delivery and surgical specimen quality will be closely monitored. Ethics and dissemination The trial is approved by the Regional Ethics Committee and Health Research Authority (HRA) or equivalent. Written informed consent will be obtained. Serious adverse events will be reported to Swansea Trials Unit (STU), the ethics committee and trial sites. Trial results will be submitted for peer review

    Enhanced recovery (ER) programs are policies and protocols meant to improve postoperative recovery after surgery. As a consequence of a smoother recovery, patients can be discharged early. This paper describes the impact of an ER program in colorectal surgery in a rural hospital. In total, 132 patients had colorectal resection within the ER program. Data were collected prospectively. The ER pathway affects perioperative management in the following ways in order to: (1) improve patient's general condition before surgery, (2) minimize intraoperative surgical trauma by using a laparoscopic approach in all cases, and (3) facilitation of a quicker postoperative return of physiological function. Most (86.4%) of the patients have been operated as elective cases and for a cancer (73.5%). Laparoscopic resection was performed in 63.6% of patients, with a conversion rate of 10.6%. Total morbidity was 18.2%, leak rate was 1.5%, and 90-day mortality rate was 3%. Overall median postoperative stay was 6.5 days. Total length of in-hospital stay was lower in laparoscopic resections (5.5 d), elective cases (6 d), and in younger patients (6 d). Age and laparoscopic access were independent prognostic factors significantly associated with early discharge in elective patients. Overall readmission rate was 9.1% and this was not affected by any preoperative or intraoperative factor within those in this study. The ER program positively impacted the outcome of colorectal resections also in our rural setting. Discharging patients expeditiously did not affect postoperative morbidity or readmission rate.

    Background: Radical cystectomy (RC) is associated with high risk of early and late perioperative complications, and readmissions. The Enhanced Recovery After Surgery (ERAS) protocol has been applied to RC showing decreased hospital stay without increased morbidity. Objective: To evaluate the specific causes of hospital readmissions in RC patients treated before and after adoption of an ERAS protocol at our institution. Methods: We retrospectively evaluated the outcome of 207 RC patients on ERAS protocol at the Stanford University Hospital from January 2012 to December 2014. We focused on early (30-day) and late (90-day) postoperative readmission rate and causes. Results were compared with a pre-ERAS consecutive series of 177 RC patients from January 2009 to December 2011. Results: In the post-ERAS time period a total of 56 patients were readmitted, 41 within the first 30 days after surgery (20%) and 15 within the following 60 days (7%). Fever, often associated with dehydration, was the most common reason for presentation to the hospital, accounting for 57% of all readmissions. At 90 days infection accounted for 53% of readmissions. Of all the patients readmitted during the first 90 days after surgery, 32 had positive urine cultures, mostly caused by Enterococcus faecalis isolated in 18 (56%). Readmission rates did not increase since the introduction of the ERAS protocol, with an incidence of 27% in the post-ERAS group versus 30% in the pre-ERAS group. Conclusions: Despite accurate adherence to most recent perioperative antibiotic guidelines, the incidence of readmissions after RC due to infection still remains significant. PMID:28149935

    Full Text Available Abstract Background Coronary artery bypass graft (CABG surgery is the standard of care in the treatment of advanced coronary artery disease, and its long-term results are affected by the failure of bypass grafts. The aim of the present study was to evaluate the early patency rate in coronary bypass grafts. Methods A total of 107 consecutive patients who underwent CABG were included in this study. Early graft patency was evaluated via computed tomography (CT angiography in the first week after surgery. Results There were a total of 366 grafts, comprised of 250 venous grafts and 116 arterial grafts. Multi-slice CT detected acute graft occlusions in 32 (8.7% of all the grafts, including 26 (10% of the 250 venous grafts and 6 (5% of the 116 arterial grafts. The patency rates obtained were 97.3% for the left internal mammary (IMA grafts, 50% for the radial artery grafts, and 50% for the right IMA grafts. Additionally, 107 (96.4% grafts to the left anterior descending artery (LAD were classified as patent, whereas 1 (30% of the 3 grafts in the left circumflex (LCX region and 1 (50% of the 2 grafts in the right coronary artery (RCA territory were found to be occluded. In the venous category, 8 (13.7% of the 58 grafts to LAD were found to be occluded. In the LCX region, 9 (8.5% of the 106 grafts were classified as occluded, while the remaining 97 (91.5% grafts were patent. The venous grafts to RCA were occluded in 9 (10.4% of the 86 grafts. Amongst the multiple preoperative, intraoperative, and postoperative factors, pump time was significantly longer in the patients with occluded grafts than in those with patent grafts (P = 0.04. Conclusion The IMA grafts had the highest early patency rate amongst the coronary bypass grafts. However, the other arterial grafts were associated with a high rate of acute occlusions.

    The da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2014 to facilitate minimally invasive surgery. Novel features are targeted towards facilitating complex multi-quadrant procedures, but data is scarce so far. Perioperative data of patients who underwent robotic general surgery with the da Vinci Xi system within the first 6 month after installation were collected and analyzed. The gastric bypass procedures performed with the da Vinci Xi Surgical System were compared to an equal amount of the last procedures with the da Vinci Si Surgical System. Thirty-one foregut (28 Roux-en-Y gastric bypasses), 6 colorectal procedures and 1 revisional biliary procedure were performed. The mean operating room (OR) time was 221.8 (±69.0) minutes for gastric bypasses and 306.5 (±48.8) for colorectal procedures with mean docking time of 9.4 (±3.8) minutes. The gastric bypass procedure was transitioned from a hybrid to a fully robotic approach. In comparison to the last 28 gastric bypass procedures performed with the da Vinci Si Surgical System, the OR time was comparable (226.9 versus 230.6 min, p = 0.8094), but the docking time significantly longer with the da Vinci Xi Surgical System (8.5 versus 6.1 min, p = 0.0415). All colorectal procedures were performed with a single robotic docking. No intraoperative and two postoperative complications occurred. The da Vinci Xi might facilitate single-setups of totally robotic gastric bypass and colorectal surgeries. However, further comparable research is needed to clearly determine the significance of this latest version of the da Vinci Surgical System.

    Purpose: To retrospectively evaluate treatment results and toxicity following a combined approach consisting of neoadjuvant radiochemotherapy and radical surgery in advanced adenocarcinoma of the esophagus and gastroesophageal junction. Patients and Methods: Between 2005 and 2009, a total of 41 consecutive patients with newly diagnosed nonmetastatic adenocarcinoma of the esophagus and the esophagogastric junction were evaluated, of whom 23 received neoadjuvant radiochemo-therapy (RCT). A total dose of 50.4 Gy with 2 cycles of simultaneous cisplatin/5-fluorouracil (FU) or Taxol/FU-chemotherapy were applied. A radical transthoracic subtotal esophageal and proximal gastric resection through a right thoracoabdominal laparotomy with intrathoracic anastomosis was performed 6-8 weeks following RCT. This was combined with a two-field lymphadenectomy of mediastinal and abdominal lymph nodes. Standard histopathological evaluation included the application of regression grading according to Werner and Hoefler. Toxicity was recorded on the basis of CTC criteria; survival curves were calculated according to Kaplan-Meier. V10, V15, and V20 data were correlated with pulmonary toxicity. Results: Overall survival for all 23 patients was 61% at 3 years. Of the original 23 patients, 18 (78%) patients proceeded to radical surgery. Reasons for no surgery included advanced age of 79, 82, and 86 years (n = 3), severe comorbidity (n = 1), and progression during radiochemotherapy (n = 1). Surgical morbidity (grade 3-4) and mortality rates were 35% and 6%, respectively. Resurgery was necessary in 3 cases (18%). Clear resection margins were achieved in 17 of 18 patients (94%).

    Full Text Available AIM: To assess the feasibility and safety of early oral feeding (EOF after gastrectomy for gastric cancer through a systematic review and meta-analysis based on randomized controlled trials. METHODS: A literature search in PubMed, Embase, Web of Science and Cochrane library databases was performed for eligible studies published between January 1995 and March 2014. Systematic review was carried out to identify randomized controlled trials comparing EOF and traditional postoperative oral feeding after gastric cancer surgery. Meta-analyses were performed by either a fixed effects model or a random effects model according to the heterogeneity using RevMan 5.2 software. RESULTS: Six studies remained for final analysis. Included studies were published between 2005 and 2013 reporting on a total of 454 patients. No significant differences were observed for postoperative complication (RR = 0.95; 95%CI, 0.70 to 1.29; P = 0.75, the tolerability of oral feeding (RR = 0.98; 95%CI, 0.91 to 1.06; P = 0.61, readmission rate (RR = 1; 95%CI, 0.30 to 3.31; P = 1.00 and incidence of anastomotic leakage (RR = 0.31; 95%CI, 0.01 to 7.30; P = 0.47 between two groups. EOF after gastrectomy for gastric cancer was associated with significant shorter duration of the hospital stay (WMD = -2.36; 95%CI, -3.37 to -1.34; P<0.0001 and time to first flatus (WMD = -19.94; 95%CI, -32.03 to -7.84; P = 0.001. There were no significant differences in postoperative complication, tolerability of oral feeding, readmission rates, duration of hospital stay and time to first flatus among subgroups stratified by the time to start EOF or by partial and total gastrectomy or by laparoscopic and open surgery. CONCLUSIONS: The result of this meta-analysis showed that EOF after gastric cancer surgery seems feasible and safe, even started at the day of surgery irrespective of the extent of the gastric resection and the type of surgery.

    Diode laser welding of ocular tissues is a procedure that enables minimally invasive closure of a corneal wound. This procedure is based on a photothermal effect: a water solution of Indocyanine Green (ICG) is inserted in the surgical wound, in order to stain the corneal tissue walls. The stained tissue is then irradiated with a low power infrared diode laser, delivering laser light through a 300-μm core diameter optical fiber. This procedure enables an immediate closure of the wounds: it is thus possible to reduce or to substitute the use of surgical threads. This is of particular interest in children, because the immediate closure improves refractive outcome and anti-amblyopic effect; moreover this procedure avoids several general anaesthesia for suture management. In this work, we present the first use of diode laser welding procedure in paediatric patients. 5 selected patients underwent cataract surgery (Group 1), while 4 underwent fs-laserassisted penetrating keratoplasty (Group 2). In Group 1 the conventional surgery procedure was performed, while no stitches were used for the closure of the surgical wounds: these were laser welded and immediately closed. In Group 2 the donor button was sutured upon the recipient by 8 single stitches, instead of 16 single stitches or a running suture. The laser welding procedure was performed in order to join the donor tissue to the recipient bed. Objective observations in the follow up study evidenced a perfect adhesion of the laser welded tissues, no collateral effects and an optimal restoration of the treated tissues.

    Disease relapses occur in up to 40% of cases after radiotherapy (RT) for early-stage glottic laryngeal neoplasms, and the foremost remaining treatment option is salvage total laryngectomy (STL). Our objectives were to review the outcomes of patients treated with salvage surgery after RT for early-stage carcinoma of the glottic larynx and to assess prognostic factors. We retrospectively analyzed 43 patients who underwent surgery. Overall and disease-free survival rates among subgroups were calculated and compared, stratified by preoperative stage, vocal cord mobility and postoperative histopathologic data. Recurrences occurred 22.7 months after the end of RT. Surgery was STL in 33 cases (76.8%). The main prognostic factors associated with survival rates were initial vocal cord mobility, vocal cord mobility at the diagnosis of recurrence, and changes in mobility. Vocal cord mobility is an important clinical criterion in treatment decision making for early-stage glottis carcinoma and remains important during follow-up.

    Hydroxyapatite (HA), fluor-hydroxyapatite (FHA) with varying levels of fluoride ion substitution and fluorapatite (FA) were synthesised by the sol-gel method as possible implant coating or bone-grafting materials. Calcium nitrate and triethyl phosphite were used as precursors under an ethanol-water based solution. Different amounts of ammonium fluoride were incorporated for the preparation of the FHA and FA sol-gels. After heating and powdering the sol-gels, dissolution behaviour was assessed using ion chromatography to measure Ca(2+) and PO4 (3-) ion release. Biological behaviour was assessed using cellular proliferation with human osteosarcoma cells and alamarBlue™ assay. Statistical analysis was performed with a two way analysis of variance and post hoc testing with a Bonferroni correction. Increasing fluoride substitution into an apatite structure decreased the dissolution rate. Increasing the firing temperature of the HA, FHA and FA sol-gels up to 1,000 °C decreased the dissolution rate. There was significantly higher cellular proliferation on highly substituted FHA and FA than on HA or Titanium. The properties of an implant coating or bone grafting material can be tailored to meet specific requirements by altering the amount of fluoride that is incorporated into the original apatite structure. The dissolution behaviour can further be altered by the temperature at which the sol-gel is fired.

The patients were reviewed for indications, complications, length of hospital stay, and conversion rate, as well as console and docking times.Results: Over the three-year period, we operated on 35 patients with benign or malignant conditions using the robot for a total of 62 surgical procedures. The docking times averaged seven minutes. The mean console times for simple hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic lymphadenectomy were 125, 47, and 62 minutes, respectively. In four patients, laparoscopic procedures were converted to open procedures, giving a conversion rate of 6.5%. All of the conversions were among the first 15 procedures performed. The average hospital stay was 3 days. Complications occurred in five patients (14%, and none were directly related to the robotic system.Conclusion: Our early experience with the robot show that with proper training of the robotic team, technical difficulty with the robotic system is limited. There is definitely a learning curve that requires performance of gynecological surgical procedures using the robot.Keywords: da Vinci robot, gynecological surgery, laparoscopy

To assess the feasibility of these echocardiographic measurements. A cross-sectional study, double-blind pilot study was carried out from May 2011 to February 2013. Cardiovascular postoperative critical care at the National Institute of Cardiology "Ignacio Chávez", Mexico City, Mexico. Consecutive, non-probabilistic sampling. Fifty-six patients were studied in the postoperative period of cardiac surgery. The first echocardiographic parameters were obtained between 6-8hours after cardiac surgery, followed by blinded second measurements. Tricuspid annular plane systolic excursion (TAPSE), tricuspid annular peak systolic velocity on tissue Doppler imaging (VSPAT), diameters and right ventricular outflow area, tract fractional shortening. The agreement was analyzed by the Bland-Altman method, and its magnitude was assessed by the intraclass correlation coefficient (95% confidence interval). Both observers evaluated TAPSE and VSPAT in 48 patients (92%). The average TAPSE was 11.68±4.53mm (range 4-27mm). Right ventricular systolic dysfunction was observed in 41 cases (85%) and normal TAPSE in 7 patients (15%). The average difference and its limits according to TAPSE were -0.917±2.95 (-6.821, 4.988), with a magnitude of 0.725 (0.552, 0.837); the tricuspid annular peak systolic velocity on tissue Doppler imaging was -0.001±0.015 (-0.031, 0.030), and its magnitude 0.825 (0.708, 0.898), respectively. VSPAT and TAPSE were estimated by both observers in 92% of the patients, these parameters exhibiting the lowest interobserver variability. Copyright © 2016 Elsevier España, S.L.U. y SEMICYUC.

    2016-10-01

    Early dumping syndrome after gastric bypass surgery due to rapid delivery of hyperosmolar nutrients into the bowel causing intense symptoms is often described as a complication. Twelve patients, mean age 47 years, were interviewed approximately 9 years post-operation. The interviews were audiotaped and transcribed verbatim, followed by an inductive content analysis to reveal patients' experience of the dumping syndrome. The core category 'Dumping syndrome is a positive consequence of Roux-en-Y gastric bypass surgery and a tool to control food intake' was identified based on the following four sub-categories: (i) 'The multidimensional emergence and effects of dumping syndrome', (ii) 'Dumping syndrome as something positive although unpleasant', (iii) 'Developing coping mechanisms and ingenious strategies' and (iv) 'My own fault if I expose myself to dumping syndrome'. From the patients' perspective, dumping syndrome gives control over food intake; although the symptoms were unpleasant, patients considered dumping syndrome as a positive protection against over-consumption. Hence, healthcare professionals should not present dumping syndrome as a complication but rather as an aid to control eating behaviour and excessive food intake.

    Objective: The aim of this study was to identify clinicopathological factors predictive of lymph node metastasis (LNM) in intramucosal poorly differentiated early gastric cancer (EGC), and further to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC. Methods: Data from 65 patients with intramucosal poorly differentiated EGC and surgically treated were collected, and the association between the clinicopathological factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses. Results:Univariate analysis showed that number of tumors, tumor size and lymphatic vessel involvement (LVI) were the significant and independent risk factors for LNM (all P < 0.05). The LNM rates were 5.0%, 18.2% and 66.7%, respectively. There was no LNM in 31 patients without the three risk clinicopathological factors. Conclusion: The number of tumors, tumor size, and LVI are independently associated with the presence of LNM in intramucosal poorly differentiated EGC. Thus, these three risk factors may be used to set as a simple criterion to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC.

  4. Should patients with early breast cancer still be offered the choice of breast conserving surgery or mastectomy?

    Science.gov (United States)

    Johns, N; Dixon, J M

    2016-11-01

    Breast conserving therapy (BCT) for breast cancer aims to achieve long-term local disease control with reduced local morbidity. BCT has similar long-term survival outcomes to mastectomy in patients with early breast cancer and recent studies have reported similar rates of recurrence compared with mastectomy. An increasing number of studies have shown improved overall survival among women treated with BCT regardless of cancer phenotype compared with mastectomy. Despite BCT being at least equivalent in outcome to mastectomy many women with small breast cancers continue to be treated by mastectomy and several studies in the last decade have shown a trend of increasing numbers of unilateral and bilateral mastectomies. The advent of increasingly effective neoadjuvant treatment has allowed even more women to have breast conservation. Not only has neoadjuvant therapy been shown to increase the rates of BCT, it does so without increasing in breast recurrence rates. Patients who are suitable for BCT should be advised that BCT is the best treatment option for them. They should be informed that not only does it confer at least equivalent survival and local recurrence rates but that compared with mastectomy it has the advantages of less complications, better quality of life and many less operations if reconstructive surgery is performed. It may no longer be appropriate to offer women suitable for BCT the choice of mastectomy or BCT.

    Sepsis remains a significant source of mortality among hospitalized patients. This study examines the usage of a vital sign-based screening protocol in identifying postoperative patients at risk for sepsis at an academic-affiliated medical center. We identified all general surgery inpatients undergoing abdominopelvic surgery from January to June 2014, and compared those with positive screening tests to a sample of screen-negative controls. Multivariate logistic regression was used to identify predictors of positive screening tests and progression to severe sepsis. In total, 478 patients underwent abdominopelvic operations, 59 had positive screening tests, 33 qualified for sepsis, and six progressed to severe sepsis. Predictors of a positive screening test were presence of cancer [odds ratio (OR) 30.7, 95% confidence interval (CI) 2.2-420], emergency operation (OR 6.5, 95% CI 1.7-24), longer operative time (OR 2.2/h, 95% CI 1.2-4.1), and presence of postoperative infection (OR 6.4, 95% CI 1.5-27). The screening protocol had sensitivity 100 per cent and specificity 88 per cent for severe sepsis. We identified no predictors of severe sepsis. In conclusion, vital sign-based screening provides value by drawing early attention to patients with potential to develop sepsis, but escalation of care for these patients should be based on clinical judgment.

    OBJECTIVE Recent studies have indicated that a signal intensity increase of the fluid within the resection cavity on FLAIR images may predict tumor recurrence after glioma surgery. The aim of this study was to assess the increase in FLAIR signal intensity in a large patient cohort and in subgroups to assess its prognostic value for early tumor recurrence in glioma patients. METHODS A total of 212 patients (213 cases) who had undergone surgery for an intracranial glioma (WHO Grade IV [n = 103], WHO Grade III [n = 57], and WHO Grade II [n = 53]) were included in this retrospective study. FLAIR signal within the resection cavity at the time of tumor recurrence/last contact and on the previous MRI study was assessed qualitatively and quantitatively. Appearance of FLAIR signal increase was studied over time using Kaplan-Meier estimates in subgroups. RESULTS Patients with WHO Grade II glioma and connection of the resection cavity to CSF who did not undergo radiotherapy did not regularly develop this sign and were excluded from further analysis. For the remaining 87 cases, FLAIR signal intensity increase was observed in 27 cases. Recurrent disease was found in 26 of these 27 cases, resulting in a specificity of 80.0%, a sensitivity of 31.7%, and positive and negative predictive values of 96.3% and 6.7%, respectively. In 4 cases this sign had been observed prior (range 2.8-8.5 months) to tumor recurrence defined by standard criteria. Quantitative analysis underlined the results of qualitative analysis, but it did not add a diagnostic value. CONCLUSIONS Signal intensity increase of the fluid within the resection cavity on FLAIR images is a rare but highly specific and early sign for tumor recurrence/tumor progression in completely and incompletely resected high-grade glioma without connection of the resection cavity to CSF and with radiotherapy.

    The surgical boarding of Crohn's disease (CD) admitted as a last effort of treatment against behavior in those the therapy prescribes it has failed, it supposes a loss on perspective that can postpone the delay in the recovery of patients and it retracts them of a better quality of life when it is considered that 50% of patients maintain inactive illness during years after selected surgical procedures; some rate no reached by the most effective treatments. The risk to specify surgical procedure in the course of CD rises to 75% of payees, more than 50% in the first year from the diagnosis, and practically 100% patients in the evolution when it is contemplated to attend perianal lesions. Therefore gastroenterologist should be trained in the selection who, when and why these patients should be operated. To retard the surgery to advanced illness phases increases morbidity, and if it is certain that the new biological therapy allow induction of remissions it is also it that to increase the duration of the process and the patient s age and contributes to face bigger surgical risk and worse perspectives in the treatment of their acute complications and also chronic manifestations often clinically inconsiderate as: Retractile mesenteritis, the states of hipercoagulability and the appearance of malignizations phenomena. Saving absolute indications for initial selective surgery in management of CD patient like: Massive intestinal bleeding, toxic megacolon or free perforation, other surgical conditions they should be reevaluated on light of our current knowledge. Patient s genotyping constitutes a clinical element that contributes to the identification of its specific risks and it facilitates the therapeutic selection. Unfortunately until these analyses can be routinely used the precocious employment of CD surgery it will be based on the consideration clinical data: The patient age, its nutritional state, smoking, and the necessities of steroids.

    Highlights: • The fluorapatite mineral extracted from tooth enamel shows TL properties. • The pre-irradiation annealing process affects the TL glow curve shape. • A huge increase was observed in maximum TL for sample annealed at 1100 °C. • Annealing about 120 min causes a huge enhancement in maximum TL peak intensity • The best reproducibility is obtained at 1000 °C of annealing temperature. - Abstract: Fluorapatite Ca{sub 5}F(PO{sub 4}){sub 3} is a kind of important thermoluminescence dosimeter (TLD) material, because the effective atomic number of fluorapatite is close to that of human bones and teeth. In the present study, thermoluminescence (TL) properties of fluorapatite mineral in tooth enamel under the different annealing temperatures with various annealing times were investigated. This study reveals that the fluorapatite in tooth enamel exhibits TL properties. Annealing of the sample affects extremely the TL glow curve and causes a huge enhancement in the sensitization of TL peak. The sample annealed at 1000 °C about 120 min gives best TL peak intensity (150 factors than un-annealed sample) and has a distinct peak around 230 °C. Also, the best reproducibility was observed for 1000 °C annealed sample temperature while un-annealed sample shows the worst reproducibility. Moreover, a good linearity in dose response is observed in the samples annealed at 400 °C and 700 °C.

    Background Video-assisted thoracic surgery (VATS) has been shown to effectively reduce postoperative pain, enhance mobilization of the patients, shorten in-hospital length of stay, and minimize postoperative morbidity rates. The aim of this prospective study is to evaluate neuroendocrine and respiratory parameters as stress markers in cancer patients who underwent lung wedge resections, using both mini muscle-sparing thoracotomy and VATS approach. Methods The patients were randomly allocated into two groups: Group A (n=30) involved patients who were operated on using the VATS approach, while in group B (n=30), the mini muscle-sparing thoracotomy approach was used. Neuroendocrine and biological variables assessed included blood glucose levels, C-reactive protein (CRP) levels, cortisol, epinephrine, and adrenocorticotropic hormone (ACTH) levels. Arterial oxygen (PaO2) and carbon dioxide (PaCO2) partial pressure were also evaluated. All parameters were measured at the following time points: 24 hours preoperatively (T1), 4 hours (T2), 24 hours (T3), 48 hours (T4), and 72 hours (T5), after the procedure. Results PaO2 levels were significantly higher 4 and 24 hours postoperatively in group A vs group B, respectively (T2: 94.3 vs 77.9 mmHg, P=0.015, T3: 96.4 vs 88.7 mmHg, P=0.034). Blood glucose (T2: 148 vs 163 mg/dL, P=0.045, T3: 133 vs 159 mg/dL, P=0.009) and CRP values (T2: 1.6 vs 2.5 mg/dL, P=0.024, T3: 1.5 vs 2.1 mg/dL, P=0.044) were found increased in both groups 4 and 24 hours after the procedure. However, their levels were significantly lower in the VATS group of patients. ACTH and cortisol values were elevated immediately after the operation and became normal after 48 hours in both groups, without significant difference. Postoperative epinephrine levels measured in group A vs group B, respectively, (T2: 78.9 vs 115.6 ng/L, P=0.007, T3: 83.4 vs 122.5 ng/L, P=0.012, T4: 67.4 vs 102.6 ng/L, P=0.021). The levels were significantly higher in group B. Conclusion This

    Purpose: To evaluate cosmetic outcome and its association with breast wound seroma after breast-conserving surgery (BCS) with targeted intraoperative radiation therapy (tIORT) boost for early breast cancer. Methods and Materials: An analysis of a single-arm prospective study of 55 patients with early breast cancer treated with BCS and tIORT boost followed by conventional whole breast radiation therapy (WBRT) between August 2003 and January 2006 was performed. A seroma was defined as a fluid collection at the primary tumor resection site identified clinically or radiologically. Cosmetic assessments using the European Organization for Research and Treatment of Cancer rating system were performed at baseline before BCS and 30 months after WBRT was completed. Results: Twenty-eight patients (51%) developed a seroma, with 18 patients (33%) requiring at least 1 aspiration. Tumor location was significantly associated with seroma formation (P=.001). Ten of 11 patients with an upper inner quadrant tumor developed a seroma. Excellent or good overall cosmetic outcome at 30 months was observed in 34 patients (62%, 95% confidence interval 53%-80%). Seroma formation was not associated with the overall cosmetic result (P=.54). Conclusion: BCS with tIORT boost followed by WBRT was associated with an acceptable cosmetic outcome. Seroma formation was not significantly associated with an adverse cosmetic outcome.

    We aimed to compare clinical outcomes and early adverse events of operative management (OM), nonoperative management (NOM), and NOM with splenic artery embolization (SAE) in blunt splenic injury (BSI) and identify the prognostic factors. Medical records of 136 consecutive patients with BSI admitted to a trauma center from 2005 to 2010 were retrospectively reviewed. Patients were separated into three groups: OM, NOM, and SAE. We focused on associated injuries and early adverse events. Multivariate analysis was performed on 23 prognostic factors to find predictors. The total survival rate was 97.1%, with four deaths all occurred in the OM group. The spleen salvage rate was 91% in NOM and SAE. At least one adverse event was observed in 32.8%, 62%, and 96% of patients in NOM, SAE, and OM groups, respectively (P events: simplified acute physiology score 2 ≥25 for almost all adverse events, age ≥50 years for acute respiratory syndrome, limb fracture for secondary bleeding, thoracic injury for pleural drainage, and at least one associated injury for pseudocyst. Adverse events were not related to the type of BSI management. Patients with BSI present worse outcome and more adverse events in OM, but this is related to the severity of injury. The main predictor of adverse events remains the severity of injury.

    Full Text Available Here we describe the findings of a unique example of the early techniques adopted in neurosurgery around 5000 years ago, consisting in a double well healed skull trephination associated with a post-cranial traumatic event occurring intra vitam to a young male from the Early Chalcolithic cemetery of Pontecagnano (South Italy, ca. 4,900 - 4,500 cal BP. Morphological, X-ray and 3D-CT scan skull-cap evaluation revealed that the main orifice was produced by scraping, obtained by clockwise rotary motion of a right-handed surgeon facing the patient, while the partial trephination was carried out by using a stone point as a drilling tool. In both cases, bone regrowth is indicative of the individual's prolonged postoperative survival and his near-complete recovery. The right femur shows a poorly healed mid-shaft fracture presumably induced by a high energy injury, and a resulting chronic osteomyelitis, affecting both femurs by hematogenous spread of the infection. Our observations on the visual and radiological features of skull and femur lesions, along with evidence on the timing of experimental bone regrowth vs. healing of lower limb fractures associated to long-term bone infections now suggest that this young man underwent a double skull trephination in order to alleviate his extremely painful condition induced by chronic osteomyelitis, which is thought to have been the cause of death.

    Background: Radiotherapy and laser resection are established treatment modalities for early glottic carcinoma. To date, there is no confirmed conclusion which treatment is better for early glottic cancer. The objective of this study was to conduct a meta-analysis to compare the voice outcomes after laser resection (LS) and radiotherapy (RT) of Tis-T1N0M0 glottic carcinoma. Methods: we searched the relevant electronic studies and performed a meta-analysis based on 13 published studies. The Chi-square based I2-statistic test was performed to evaluate possible heterogeneity across the studies. Additionally, random-effects models were used to calculate mean differences with 95% confidence intervals (CIs). Results: Overall, a total of 13 published studies were included in our study, with 368 patients in the RT group and 440 patients in the LS group, respectively. No significant differences in Voice Handicap Index (VHI), jitter and shimmer were found between RT and endoscopic LS among patients with Tis-T1N0M0 glottic carcinoma and T1aN0M0 laryngeal cancer. However, the acoustic voice analysis parameters of Fo values were significantly lower in RT group than that in LS group. Conclusion: The results from this meta-analysis support that the LS has more advantages than RT in terms of voice quality. However, more studies on voice outcome need to validate our findings.

    The ideal age to perform the Fontan procedure is still unknown. The aim of this study is to determine outcomes after Fontan surgery delayed to adolescence and adulthood in Australia and New Zealand. Patients who had undergone a Fontan procedure at 15 years of age or older were identified in the 1133 patients registered in the Australia and New Zealand Fontan Registry until December 2012. A total of 45 patients underwent the following Fontan procedure at a median age of 18.3 years (16-21 years): 24 atriopulmonary connections, 10 lateral tunnel, and 11 extracardiac conduits. Hospital mortality was 13% (6 of 45). After a mean follow-up of 15.5 ± 9 years, there were 8 late deaths. Survival rates after 10, 20, and 25 years were 79% (95% CI: 64-89), 70% (95% CI: 51-83), and 70% (95% CI: 51-83), respectively. Freedom from Fontan failure (death, heart transplantation, Fontan takedown, protein-losing enteropathy, and poor functional status) after 10 and 20 years was 63% (95% CI: 47-76) and 35% (95% CI: 19-52), respectively. Patients with a single left ventricle had a lower risk of failure (hazard ratio = 0.25, 95% CI: 0.10-0.59; P = 0.002). Arrhythmias developed in 29 patients after a median of 0.1 years (0-9.3 years) and 10 required a permanent pacemaker. Freedom from all adverse events at 10 years was 30% (95% CI: 16-45). Outcomes of the Fontan procedure in adolescents and adults are poor, with disproportionately high hospital mortality and late adverse events. The Fontan procedure should not be delayed to adolescence and adulthood and should be performed electively in childhood.

    Background Different kinds of minimally invasive surgery (MIS) procedures have now been used in total knee arthroplasty (TKA). Compared with traditional TKA procedure with a long skin incision, clinical studies showed MIS procedures had some advantages. Quadriceps sparing (QS) procedures are the most minimally invasive MIS procedure until now. This study was aimed to find the insertion types for Chinese patients' vastus medialis and if the QS procedure had some advantages in patients' early recovery.Methods Between February 2006 and May 2007, 120 consecutive patients underwent unilateral primary TKA under general anesthesia, among whom 14 patients were lost to follow-up, the remaining 106 cases were enrolled in this study. Among the 106 cases there were 85 right knees, 21 left knees (15 men and 91 women, with a mean age of 65.1±7.4 years); osteoarthritis in 97 patients (91.5%) and rheumatoid arthritis in 9 patients (8.5%). MIS TKA was performed in 49 cases (MIS TKA group), while MIS-QS TKA in 57 cases (MIS-QS TKA group). During the operation, the type Ⅰ, Ⅱ and Ⅲ insertions of the vastus medialis for all patients were recorded. Each knee was rated post-operatively according to the Hospital of Special Surgery (HSS) scoring system. Clinical follow-up was undertaken at 1 week, 2, 6, 12 and 24 weeks. Operating time and complications were recorded.Results There was no statistically significant difference between the two groups for gender distribution, age, left or right knee incidence, pre-operative diagnosis, incidence of varus or valgus deformity. Of the 106 cases there was 1 (0.9%) case with a type Ⅰ insertion of the vastus medialis, 4 (3.8%) cases with type Ⅱ insertions, 101 (95.3%) cases with type Ⅲ insertions. The HSS scoring was significantly different between the MIS-QS TKA group and MIS TKA group within the first two weeks post operation. From 2 weeks later to 24 weeks, no significant difference was found. The average operating time was (53.3±12

    Pericardial or mediastinal hemorrhage requiring reoperation occurs in 2% to 5% of patients, usually early (0 to 48 hours), after open-heart surgery. This hemorrhage may be occult, and resulting cardiac tamponade may easily be misinterpreted as ventricular dysfunction, common early postoperatively. In such cases, appropriate and timely intervention may not occur. Of 50 patients evaluated by technetium-99m red blood cell gated equilibrium radionuclide ventriculography (RNV) because of early postoperative cardiogenic shock of uncertain etiology, 17 had unique scintigraphic images suggestive of intrathoracic hemorrhage. Of these 17, 5 had a generalized halo of abnormal radioactivity surrounding small hyperdynamic right and left ventricles, 11 had localized regions of intense blood pool activity outside the cardiac chambers (two with compression of single chambers), and one demonstrated marked radionuclide activity in the right hemithorax (2000 ml of blood at reoperation). Twelve patients had exploratory reoperation for control of hemorrhage as a direct result of the scintigraphic findings, three were successfully treated with fresh frozen plasma and platelet infusions along with medical interventions to optimize cardiac performance, and two patients died in cardiogenic shock (presumed tamponade) without reoperation. In the 12 reoperated patients, all were confirmed to have active pericardial bleeding. Scintigraphic localization of abnormal blood pools within the pericardium corresponded to the sites at which active bleeding was witnessed at reoperation. The abnormal bleeding was etiologically related to the tamponade state, with marked improvement in hemodynamics after reoperation. Nine additional patients were reoperated for presumed tamponade after RNV revealed an exaggerated halo of photon deficiency surrounding the cardiac chambers.

    Selection of the treatment method in breast cancer patients and its consequences may affect their quality of life through somatic, psychical, and social factors. The aim of the study was early evaluation of the quality of life of women after mastectomy vs. breast conserving surgery. The study included 100 women aged 31 to 79 years (mean: 57) who underwent surgery due to breast cancer (amputation: 52; breast conserving surgery: 48 women) at the Cancer Centre in Bydgoszcz in 2014. The QLQ C-30 and QLQ BR-23 questionnaires were used to evaluate the quality of life of the patients 3 months after surgery. In the Global Health Status/QoL domain, the mean score for women after amputation and breast conserving surgery was 49 and 53, respectively; for Physical Functioning, the scores were 70 and 75, and for Role Functioning, 62 and 68, respectively. For Cognitive Functioning, the mean score was 74 and 73; for Emotional Functioning - 62 and 68, and for Social Functioning 64 and 60, respectively. The difference in the arm symptoms domain was significant at 46 and 33 points, respectively (p = 0.004). The patients treated with breast conserving surgery had a better body image than women after amputation - the mean score was 52 and 66, respectively (p = 0.01). With respect to Global Health Status/QoL and Physical Functioning, the quality of life of women in the early postoperative period was similar in women after breast amputation and those who underwent breast conserving surgery. Patients treated with breast conserving surgery had a better score for body image, while those who underwent amputation more often suffered from arm symptoms, such as pain, oedema, and problems with raising of the limb.

    Hypofractionated whole breast irradiation (HF-WBI) has been proved effective and safe and even better for late or acute radiation toxicity for early breast cancer. Moreover, it improves patient convenience, quality of life and is expected to be advantageous in the medical care system by reducing overall cost. In this review, we examined key randomized trials of HF-WBI, focusing on adequate patient selection as suggested by the American Society of Therapeutic Radiology and Oncology (ASTRO) guideline and the radiobiologic aspects of HF-WBI in relation to its adoption into clinical settings. Further investigation to identify the current practice pattern or cost effectiveness is warranted under the national health insurance service system in Korea.

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

    In this study, Mg-substituted fluorapatite coatings were deposited on medical grade AISI 316L stainless steel via sol-gel dip coating method. Phase composition, crystallite size and degree of crystallinity of the obtained coatings were evaluated by X-ray diffraction (XRD) analysis. Fourier transform infrared (FTIR) spectroscopy was also used to evaluate functional groups of the obtained coatings. The surface morphology and cross-section of the final coatings were studied using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy was used to determine elemental chemical composition of the obtained coatings. In order to determine and compare the corrosion behavior of uncoated and Mg-substituted fluorapatite coated 316L stainless steel, electrochemical potentiodynamic polarization tests were performed in physiological solutions at 37 ± 1 °C. Moreover, the released metallic ions from uncoated and coated substrates were measured by inductively coupled plasma-optical emission spectrometry (ICP-OES) within 2 months of immersing in Ringer's solution at 36.5 ± 1 °C as an indication of biocompatibility. The results showed that fluoride and magnesium were successfully incorporated into apatite lattice structure and the prepared coatings were nanostructured with crystallinity of about 70%. Obtained coatings were totally crack-free and uniform and led to decrease in corrosion current densities of 316L stainless steel in physiological solutions. In addition, coated sample released much less ions such as Fe, Cr and Ni in physiological media. Therefore, it was concluded that Mg-substituted fluorapatite coatings could improve the corrosion resistance and biocompatibility of 316L stainless steel human body implants.

Therefore, it was concluded that Mg-substituted fluorapatite coatings could improve the corrosion resistance and biocompatibility of 316L stainless steel human body implants.

    The number of biomaterials used in biomedical applications has rapidly increased in the past two decades. Fluorapatite (FA) is one of the inorganic constituents of bone or teeth used for hard-tissue repairs and replacements. Fluor-hydroxyapatite (FHA) is a new synthetically prepared composite that in its structure contains the same molecular concentration of OH(-) groups and F(-) ions. The aim of this experimental investigation was to evaluate cytotoxic, genotoxic and mutagenic effects of FHA and FA eluates on Chinese hamster V79 cells and to compare them with the effects of hydroxyapatite (HA) eluate. Cytotoxicity of the biomaterials tested was evaluated by use of the cell colony-formation assay and by direct counting of the cells in each colony. Genotoxicity was assessed by single-cell gel electrophoresis (comet assay) and mutagenicity was evaluated by the Hprt gene-mutation assay and in bacterial mutagenicity tests using Salmonella typhimurium TA100. The results show that the highest test concentrations of the biomaterials (100% and 75% eluates) induced very weak inhibition of colony growth (about 10%). On the other hand, the reduction of cell number per colony induced by these concentrations was in the range from 43% to 31%. The comet assay showed that biomaterials induced DNA breaks, which increased with increasing test concentrations in the order HA

    Fluorapatite (FA) is one of the inorganic constituents of bone or teeth used for hard tissue repairs and replacements. Fluor-hydroxyapatite (FHA) is a new synthetic composite that contains the same molecular concentration of OH(-) groups and F(-) ions. The aim of this experiment was to evaluate the cellular responses of murine fibroblast NIH-3T3 cells in vitro to solid solutions of FHA and FA and to compare them with the effect of hydroxyapatite (HA). We studied 24, 48 and 72 h effects of biomaterials on cell morphology, proliferation and cell cycle of NIH-3T3 cells by eluate assay. Furthermore, we examined the ability of FHA, FA and HA to induce cell death and DNA damage. Our cytotoxic/antiproliferative studies indicated that any of tested biomaterials did not cause the total inhibition of cell division. Biomaterials induced different antiproliferative effects increasing in the order HA < FHA < FA which were time- and concentration-dependent. None of the tested biomaterials induced necrotic/apoptotic death of NIH-3T3 cells. On the other hand, after 72 h we found that FHA and FA induced G0/G1 arrest of NIH-3T3 cells, while HA did not affect any cell cycle phases. Comet assay showed that while HA demonstrated weaker genotoxicity, DNA damage induced by FHA and FA caused G0/G1 arrest of NIH-3T3 cells. Fluoridation of hydroxyapatite and different FHA and FA structure caused different cell response of NIH-3T3 cells to biomaterials.

    Hydroxyapatite (HA), fluor-hydroxyapatite (FHA) with varying levels of fluoride ion substitution and fluorapatite (FA) production has been characterised and optimised by the sol-gel method and the dissolution and biological properties of these materials were investigated. It was the objective of this study to investigate the potential bond strength and interaction of these materials with titanium. HA, FHA and FA were synthesised by a sol-gel method. Calcium nitrate and triethyl phosphite were used as precursors under an ethanol-water based solution. Different amounts of ammonium fluoride (NH4F) were incorporated for the preparation of the FHA and FA sol-gels. Using a spin coating technique the sol-gels were coated onto commercially pure titanium disks and crystallised at various temperatures. Using scanning electron microscopy (SEM) and elemental analysis, the surface characteristics, coating thickness and interaction of the Ti substrate and coating were investigated. The bond strengths of the coating to the Ti were investigated using an Instron Universal Load Testing Machine. Statistical analysis was performed with a two-way analysis of variance and post hoc testing with a Bonferroni correction. (1) Coating speed inversely influenced the coating thickness. (2) Increasing fluoride ion substitution and heating temperature significantly increased bond strength and (3) increasing fluoride ion substitution increased the coating thickness. FHA and FA synthesised using the sol-gel technique may offer a superior alternative to coating titanium implants with HA and plasma spraying. HA, FHA and FA materials synthesised by the sol-gel method may also have a use as bone grafting materials. Copyright © 2013 Academy of Dental Materials. Published by Elsevier Ltd.

    Currently, most titanium implant coatings are made using hydroxyapatite and a plasma spraying technique. There are however limitations associated with plasma spraying processes including poor adherence, high porosity and cost. An alternative method utilising the sol-gel technique offers many potential advantages but is currently lacking research data for this application. It was the objective of this study to characterise and optimise the production of Hydroxyapatite (HA), fluorhydroxyapatite (FHA) and fluorapatite (FA) using a sol-gel technique and assess the rheological properties of these materials. HA, FHA and FA were synthesised by a sol-gel method. Calcium nitrate and triethylphosphite were used as precursors under an ethanol-water based solution. Different amounts of ammonium fluoride (NH4F) were incorporated for the preparation of the sol-gel derived FHA and FA. Optimisation of the chemistry and subsequent characterisation of the sol-gel derived materials was carried out using X-ray Diffraction (XRD) and Differential Thermal Analysis (DTA). Rheology of the sol-gels was investigated using a viscometer and contact angle measurement. A protocol was established that allowed synthesis of HA, FHA and FA that were at least 99% phase pure. The more fluoride incorporated into the apatite structure; the lower the crystallisation temperature, the smaller the unit cell size (changes in the a-axis), the higher the viscosity and contact angle of the sol-gel derived apatite. A technique has been developed for the production of HA, FHA and FA by the sol-gel technique. Increasing fluoride substitution in the apatite structure alters the potential coating properties.

    Background Premenopausal breast cancer with a triple-negative phenotype (TNBC) has been associated with inferior locoregional recurrence free survival (LRFS) and overall survival (OS) after breast conserving surgery (BCS). The aim of this study is to analyze the association between age, subtype, and surgical treatment on survival in young women (≤40 years) with early breast cancer in a population with a high rate of breast cancer in young women. Methods Three hundred thirty-two patients ≤40 years old with stage I-II invasive breast cancer who underwent surgery at a single institution between 1998 and 2012 were identified retrospectively. Uni- and multivariate analysis evaluated predictors of LRFS, OS, and disease free survival (DFS). Results Most patients (64.2%) underwent BCS. Mean age and follow-up time were 35 (25 ± 3.61) years, and 72 months (range, 24–252), respectively. In multivariate analysis, multicentricity/multifocality and young age (<35 years) independently predicted for poorer DFS and OS. Those aged 35–40 years had higher LRFS and DFS than those <35 in the mastectomy group (p=0.007 and p=0.039, respectively). Patients with TNBC had lower OS compared with patients with luminal A subtype (p=0.042), and those who underwent BCS had higher OS than patients after mastectomy (p=0.015). Conclusion Young age (< 35 years) is an independent predictor of poorer OS and DFS as compared with ages 35–40, even in countries with a lower average age of breast cancer presentation. In addition, TNBC in the young predicts for poorer OS. BCS can be performed in young patients with TNBC, despite their poorer overall survival. PMID:27433412

  20. Risk factors for lymph node metastasis and evaluation of reasonable surgery for early gastric cancer

    2007-01-01

    AIM: To give the evidence for rationalizing surgical therapy for early gastric cancer with different lymph node status.METHODS: A series of 322 early gastric cancer patients who underwent gastrectomy with more than 15 lymph nodes retrieved were reviewed in this study. The rate of lymph node metastasis was calculated. Univariate and multivariate analyses were performed to evaluate the independent factors for predicting lymph node metastasis.RESULTS: No metastasis was detected in No.5, 6 lymph nodes (LN) during proximal gastric cancer total gastrectomy, and in No.10, 11p, 11d during for combined resection of spleen and splenic artery and in No.15 LN during combined resection of transverse colon mesentery. No.11p, 12a, 14v LN were proved negative for metastasis. The global metastastic rate was 14.6% for LN, 5.9% for mucosa, and 22.4% for submucosa carcinoma, respectively. The metastasis in group Ⅱ was almost limited in No.7, 8a LN. Multivariate analysis identified that the depth of invasion, histological type and lymphatic invasion were independent risk factors for LN metastasis. No metastasis from distal cancer (≤ 1.0 cm in diameter) was detected in group Ⅱ LN. The metastasis rate increased significantly when the diameter exceeded 3.0 cm. All tumors (≤ 1.0 cm in diameter) with LN metastasis and mucosa invasion showed a depressed macroscopic type, and all protruded carcinomas were >3.0 cm in diameter.CONCLUSION: Segmental/subtotal gastrectomy plus D1/D1 + No.7 should be performed for carcinoma (≤ 1.0 cm in diameter, protruded type and mucosa invasion).Subtotal gastrectomy plus D2 or D1 + No.7, 8a, 9 is the most rational operation, whereas No.11p, 12a,14v lymphadenectomy should not be recommended routinely for poorly differentiated and depressed type of submucosa carcinoma (> 3.0 cm in diameter). Total gastrectomy should not be performed in proximal, so does combined resection or D2+/D3 lymphadenectomy.

    2015-07-01

    This review evaluates the benefits and disadvantages associated with the use of robotic-assisted technology in performing lobectomies in patients with early-stage lung cancer. The author conducted a literature search of Ovid®, MEDLINE®, PubMed®, and CINAHL® for articles published from 2005 to 2013. Search criteria included key terms such as robot, robotic, robotic-assisted lobectomy, and lung cancer. Of 922 articles, the author included a total of 12 research-based published studies in the analysis and incorporated the findings into an evidence table. Results showed that robotic-assisted lobectomies are feasible safe procedures for patients with stage 1A or 1B lung cancer; however, there is a steep learning curve and long-term randomized studies evaluating robotic-assisted lobectomy and conventional posterolateral thoracotomy or video-assisted thoracic lobectomy are needed. For patient safety, perioperative nurses should be aware of the length of time and experience required to perform these procedures, the costs, techniques, benefits, and disadvantages.

    Although the benefit of surgical ablation for atrial fibrillation (AF) performed concomitant to mitral valve surgery is established, whether that performed concomitant to non-mitral cardiac surgery is beneficial remains unclear. In non-mitral, non-left-atriotomy cardiac surgery, the optimal surgical approach for AF remains to be established. Therefore, using the Japan Adult Cardiovascular Surgery Database (JACVSD), we compared 2 surgical ablation procedures [the maze procedure and pulmonary vein isolation (PVI)] performed concomitant to non-mitral cardiac surgery. Of 3402 JACVSD patients who had undergone elective non-mitral cardiac surgery by 2012, 1797 (53%) had undergone concomitant PVI, and 1339 (39%) had undergone the maze procedure. To compensate for patient heterogeneity, we conducted a propensity score-matched analysis of 1952 patients who had undergone PVI or the maze procedure (976 patients each). Operative procedures took significantly longer in the Maze Group. Although postoperative AF occurred in 34.3% of the PVI Group patients and in 31.9% of the Maze Group patients (p = 0.371), the incidence of first-time pacemaker implantation was significantly lower in the PVI Group (1.9 vs. 4.1%, respectively; p = 0.005). There was no significant difference in other morbidities or in operative mortality. Postoperative hospital and ICU stays tended to be longer in the Maze Group. Our data indicate that surgical ablation of AF concomitant to non-mitral cardiac surgery is beneficial. Furthermore, PVI and the maze procedure appear to be of equal benefit in this context, except that the maze procedure may more frequently result in the need for pacemaker implantation.

    Full Text Available The article presents a case report of a patient with a cystic bleb in the early postoperative period after trabeculectomy. Patient complained of discomfort in a recently (4 weeks operated eye. Medical regimen administered previously had been taken irregularly. Biomicroscopy revealed a high, encapsulated cystic bleb with thin walls and hyperemia. Intraocular pressure at the moment of examination was 27 mmHg. Local hypotensive therapy had been neglected by the patient. A local anti-inflammatory (tobramycin / dexamethasone fixed combination and hypotensive (brimonidine / timolol fixed combination therapy was administered. 24 hours later, when intraocular pressure decreased to 20 mmHg, a needle revision procedure was conducted for partial bleb wall destruction and subconjunctival injection of dexamethasone, fluorouracil and ranibizumab. During the next day examination the bleb was diffuse, with less hyperemia and an abundance of conjunctival microcysts in the central bleb’s zone. Intraocular pressure was 10.2 mmHg. No choroidal detachment was noted during ophthalmoscopy and OCT examination. The patient continued anti-inflammatory therapy. Another needling procedure with the same drug combination was repeated two weeks after due to an increased hyperemia. At the end of the four-week follow-up period the filtering bleb remained diffuse and the intraocular pressure was 13.2 mmHg. Dexamethasone drops were prescribed to be instilled 1‑2 times a day for a month. This case report demonstrates the method of restoring a functioning filtering bleb by the needle revision with antiinflammatory, cytostatic and anti-VEGF therapy for prolonging the hypotensive effect of a trabeculectomy in the presence of wound healing.

    Full Text Available Background: Brain type natriuretic peptide (BNP is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. It can predict post-operative complications after heart surgery in adults. We sought to investigate the prognostic value of BNP in children after heart surgery. Methods: We measured the BNP serum levels in 96 children with congenital heart diseases before, immediately after, and 12 hours after open heart surgery. We studied the ability of the post-operative BNP serum level variations to predict mortality and morbidity in children. Results: In total, 96 patients, comprising 40 (41.7% females and 56 (58.3% males with a mean age of 4.1 years (range: 1 month to 17 years, with various congenital heart diseases were studied. The rise in the serum BNP level 12 hours post surgery was directly related to mortality before discharge from hospital (P value=0.004, congestive heart failure after surgery (P value<0.001 , patients' cyanosis (P value=0.045, duration of ICU stay (r=0.342, P value=0.004, and post-operative need for inotropic drugs (P value<0.001. Conclusion: The rise in the BNP serum level 12 hours after heart surgery is a good marker for predicting mortality, morbidity, and early diagnosis of heart failure in children.

    The study included 52 patients after gastrectomy for carcinoma of the proximal part of the stomach. Endoscopic laser therapy was made in 32 patients to reduce inflammation in the anastomosis zone 2-3 weeks after surgery. Drug therapy was made in 20 patients within the same time period. Histochemical study of the biopsy material of esophageal and intestinal part of the anastomosis was carried out. It is revealed that application of copper vapor laser early after surgery reduces edema and inflammation in the anastomosis zone for 2 weeks as well as accelerates the growth of granulation tissue forming a delicate scar thus preventing formation of scar stenosis.

  7. High temperature annealing of fission tracks in fluorapatite, Santa Fe Springs oil field, Los Angeles Basin, California

    Annealing of fission tracks is a kinetic process dependent primarily on temperature and to a laser extent on time. Several kinetic models of apatite annealing have been proposed. The predictive capabilities of these models for long-term geologic annealing have been limited to qualitative or semiquantitative at best, because of uncertainties associated with (1) the extrapolation of laboratory observations to geologic conditions, (2) the thermal histories of field samples, and (3) to some extent, the effect of apatite composition on reported annealing temperatures. Thermal history in the Santa Fe Springs oil field, Los Angeles Basin, California, is constrained by an exceptionally well known burial history and present-day temperature gradient. Sediment burial histories are continuous and tightly constrained from about 9 Ma to present, with an important tie at 3.4 Ma. No surface erosion and virtually no uplift were recorded during or since deposition of these sediments, so the burial history is simple and uniquely defined. Temperature gradient (???40??C km-1) is well established from oil-field operations. Fission-track data from the Santa Fe Springs area should thus provide one critical field test of kinetic annealing models for apatite. Fission-track analysis has been performed on apatites from sandstones of Pliocene to Miocene age from a deep drill hole at Santa Fe Springs. Apatite composition, determined by electron microprobe, is fluorapatite [average composition (F1.78Cl0.01OH0.21)] with very low chlorine content [less than Durango apatite; sample means range from 0.0 to 0.04 Cl atoms, calculated on the basis of 26(O, F, Cl, OH)], suggesting that the apatite is not unusually resistant to annealing. Fission tracks are preserved in these apatites at exceptionally high present-day temperatures. Track loss is not complete until temperatures reach the extreme of 167-178??C (at 3795-4090 m depth). The temperature-time annealing relationships indicated by the new data

INTERPRETATION: VATS is associated with less postoperative pain and better quality of life than is anterolateral thoracotomy for the first year after surgery, suggesting that VATS should be the preferred......BACKGROUND: Video-assisted thoracoscopic surgery (VATS) is used increasingly as an alternative to thoracotomy for lobectomy in the treatment of early-stage non-small-cell lung cancer, but remains controversial and worldwide adoption rates are low. Non-randomised studies have suggested that VATS...

    To investigate the feasibility and superiority of transvaginal early fistula debridement and repair plus continuous vacuum aspiration via anal tube for rectovaginal fistula following rectal cancer surgery. The clinical data of four cases of rectovaginal fistula following rectal cancer surgery were retrospectively analyzed in our center. After adequate preoperative preparation, the patients underwent transvaginal fistula debridement and repair plus continuous vacuum aspiration via anal tube under continuous epidural anesthesia. After surgery and before discharge, anti-infection and nutritional support was administered for 2 d, and fluid diet and anal tube vacuum aspiration continued for 7 d. All the four cases healed. Three of them healed after one operation, and the other patient had obvious shrinkage of the fistular orifice after the first operation and underwent the same operation for a second time before complete healing. The duration of postoperative follow-up was 2, 7, 8 and 9 months respectively. No recurrence or abnormal sex life was reported. Early transvaginal fistula debridement and repair plus continuous vacuum aspiration via anal tube are feasible for rectovaginal fistula following rectal cancer surgery. This operation has many advantages, such as minimal invasiveness, short durations of operation, short treatment cycles, and easy acceptance by the patient. In addition, it does not necessitate colostomy for feces shunt and a secondary colostomy and reduction.

    The introduction of new technologies for diagnosis and screening programs led to an increasing rate of early detection of colorectal cancer. This, associated with the evolution of endoscopic techniques of local excision, led to the assessment of new strategies to reduce morbidity related to treatment, especially for early rectal cancer (ERC). Nevertheless, the definition of ERC and its staging and treatment algorithm are still under debate. The Italian Society of Colorectal Surgery developed practice guidelines to provide recommendations on the diagnosis, staging and treatment of ERC. A systematic review on the topic was performed by a multidisciplinary group of experts selected based on their clinical and scientific expertise in endoscopy, endoscopic ultrasound, magnetic resonance and surgery, with the aid of an external international audit.

    To describe 2-year and long-term outcomes (five or ten years) after resective epilepsy surgery in children operated before the age of four years. This prospective, population based, longitudinal study is based on data from the Swedish National Epilepsy Surgery Register 1995-2010. The following variables were analysed: seizure frequency, antiepileptic drug treatment (AED), neurological deficits, type of operation, histopathological diagnosis and perioperative complications. During the study period 47 children under four years had resective surgery. A majority had seizure onset within the first year of life, and the median age at surgery was two years and one month. Two thirds had neurodevelopmental abnormalities. Temporal lobe resection, frontal lobe resection and hemispherotomy predominated. A majority had malformations of cortical development. There was one major perioperative complication. At the 2-year follow-up, 21/47 children (45%) were seizure free, eight of whom were off medication. At the long-term follow-up, 16/32 (50%) were seizure-free and 11 of them off medication. Another ten (31%) had ≥75% reduction in seizure frequency. Fourteen children (44%) had sustained seizure freedom from surgery to the long-term follow-up. This is the first prospective, population based, longitudinal study to show that a favourable seizure outcome is achievable in a majority of infants and young children undergoing resective epilepsy surgery and that the improvements are consistent over time. Many can also stop taking AEDs. The findings emphasise the importance of early referral to epilepsy surgery evaluation in cases of medically intractable epilepsy in infants and young children.

    Full Text Available Objective: To evaluate the safety and efficacy of early rehabilitation after surgery program (ERAS in patients undergoing laparoscopic assisted total gastrectomy. Materials And Methods: This is a study where 47 patients who are undergoing lap assisted total gastrectomy are selected. Twenty-two (n = 22 patients received enhanced recovery programme (ERAS management and rest twenty-five (n = 25 conventional management during the perioperative period. The length of postoperative hospital stay, time to passage of first flatus, intraoperative and postoperative complications, readmission rate and 30 day mortality is compared. Serum levels of C-reactive protein pre-operatively and also on post-op day 1 and 3 are compared. Results: Postoperative hospital stay is shorter in ERAS group (78 ± 26 h when compared to conventional group (140 ± 28 h. ERAS group passed flatus earlier than conventional group (37 ± 9 h vs. 74 ± 16 h. There is no significant difference in complications between the two groups. Serum levels of CRP are significantly low in ERAS group in comparison to conventional group. [d1 (52.40 ± 10.43 g/L vs. (73.07 ± 19.32 g/L, d3 (126.10 ± 18.62 g/L vs. (160.72 ± 26.18 g/L]. Conclusion: ERAS in lap-assisted total gastrectomy is safe, feasible and efficient and it can ameliorate post-operative stress and accelerate postoperative rehabilitation in patients with gastric cancer. Short term follow up results are encouraging but we need long term studies to know its long term benefits.

    Full Text Available Spontaneous glottis closure during expiration in infants is a normal protective reflex that helps prevent alveolar and small airway collapse (due to compliant chest wall and thereby maintains functional residual capacity. Endotracheal intubation eliminates this protective mechanism and puts the infant into the risk of hypoxaemia and hypercarbia. This report sums up the early detection of airway closure in a series of three intubated small infants undergoing surgery with general anaesthesia, by the appearance of typical pigtail shaped capnogram, associated with decreased end tidal carbon dioxide and mild hypoxaemia, which was successfully managed by early institution of positive end expiratory pressure.

    The standard treatment for women with early-stage cervical cancer (IA2-IB1) remains radical hysterectomy with pelvic lymphadenectomy. In select patients interested in future fertility, the option of radical trachelectomy with pelvic lymphadenectomy is also considered a viable option. The possibility of less radical surgery may be appropriate not only for patients desiring to preserve fertility but also for all patients with low-risk early-stage cervical cancer. Recently, a number of studies have explored less radical surgical options for early-stage cervical cancer, including simple hysterectomy, simple trachelectomy, and cervical conization with or without sentinel lymph node biopsy and pelvic lymph node dissection. Such options may be available for patients with low-risk early-stage cervical cancer. Criteria that define this low-risk group include: squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma, tumor size <2 cm, stromal invasion <10mm, and no lymph-vascular space invasion. In this report, we provide a review of the existing literature on the conservative management of cervical cancer and describe ongoing multi-institutional trials evaluating the role of conservative surgery in selected patients with early-stage cervical cancer.

    The aim of this paper is a comparative study of structural stability and mechanical and optical properties of fluorapatite (FA) (Ca5(PO4)3F) and lithium disilicate (LD) (Li2Si2O5), using the first principles pseudopotential method based on density functional theory (DFT) within the generalized gradient approximation (GGA). The stability of fluorapatite and lithium disilicate compounds has been evaluated on the basis of their formation enthalpies. The results show that fluorapatite is more energetically stable than lithium disilicate. The independent elastic constants and related mechanical properties, including bulk modulus ( B), shear modulus ( G), Young's modulus ( E) and Poisson's ratio ( ν) as well as the Vickers hardness ( H v), have been calculated for fluorapatite compound and compared with other theoretical and experimental results. The obtained values of the shear modulus, Young's modulus and Vickers hardness are smaller in comparison with those of lithium disilicate compound, implying that lithium disilicate is more rigid than fluorapatite. The brittle and ductile properties were also discussed using B/ G ratio and Poisson's ratio. Optical properties such as refractive index n( ω), extinction coefficient k( ω), absorption coefficient α( ω) and optical reflectivity R( ω) have been determined from the calculations of the complex dielectric function ɛ( ω), and interpreted on the basis of the electronic structures of both compounds. The calculated values of static dielectric constant ɛ 1(0) and static refractive index n(0) show that the Li2Si2O5 compound has larger values compared to those of the Ca5(PO4)3F compound. The results of the extinction coefficient show that Li2Si2O5 compound exhibits a much stronger ultraviolet absorption. According to the absorption and reflectivity spectra, we inferred that both compounds are theoretically the best visible and infrared transparent materials.

    . The study showed a statistically significantly shorter time of treatment in the EVAR group (average 90 min compared to the OR group (average 136 min. Also, there was a statistically significantly less blood loss in the patients operated on by the use of EVAR surgery (average 60 mL as compared to the patients treated with OR techinique (average 495 mL, as well as a shorter postoperative hospitalization of patients in the EVAR group (average 4 days compared to the OR group (average 8 days. The OR group was detected with a statistically significant increase of leucocytes and statistically significant fall of the number of thrombocytes in comparison with the EVAR group in all the investigated terms. A significant concentration rise of IL-2 in the OR group and concentration rise of IL-6 in the EVAR group was shown 24 hours after the procedure, whereas on the second postoperative day there was detected a significant fall of IL-6 in the EVAR group. IL-4 concentration in the OR group was significantly higher as of the third postoperative day in comparison to the EVAR group. There was no significant difference in IL-10 concentration between the groups. Conclusion. The EVAR techinique is a safer and less invasive and less traumatic procedure for patients than the OR of AAA. Following the EVAR, there are less inflammatory reactions in the early postoperative periodas compared to the OR and therefore less possibility of the development of systemic inflammatory respons syndrome in patients treated.

    Background and Aims: Antihypertensive drugs are continued until the day of renal transplant surgery. These are associated with increased incidence of hypotension and bradycardia. Hence, this study was designed to evaluate perioperative haemodynamic and early graft functioning in renal recipients with discontinuation of antihypertensive drugs on the morning of surgery. Methods: This prospective, randomised, double-blind study recruited 120 patients. Group 1 patients received placebo tablet while Group 2 patients received usual antihypertensive drugs on the day of surgery. Perioperative haemodynamics and time for reinstitution of antihypertensives were the primary outcome measures. The secondary outcome measures were need for inotropic support and graft function. Perioperative haemodynamics were analysed using ANOVA and Student's t-tests with Bonferroni correction. Fischer's exact test was used for analysis. Results: Systolic blood pressure (SBP) declined, which was more in Group 2. Forty-one patients developed significant hypotension; a correlation was found between the maximum observed hypotension and number of antihypertensive medications (P = 0.003). Four cases had slow graft function (one in Group 1 and three in Group 2). Twenty-eight patients in Group 2 required mephentermine boluses to maintain their SBP compared to 13 patients in Group 1 (P drugs can be omitted on the morning of surgery without any haemodynamic fluctuations and graft function in controlled hypertensive end-stage renal disease renal transplant patients receiving a combined epidural and general anaesthesia.

    The aim of this prospective study was to compare the mandibular range of motion in Class III patients with and without early physiotherapy after orthognathic surgery (OGS). This study consisted of 63 Class III patients who underwent 2-jaw OGS. The experimental group comprised 31 patients who received early systematic physical rehabilitation. The control group consisted of 32 patients who did not have physical rehabilitation. Twelve variables of 3-dimensional (3D) jaw-motion analysis (JMA) were recorded before surgery (T1) and 6 weeks (T2) and 6 months (T3) after surgery. A 2-sample t test was conducted to compare the JMA results between the two groups at different time points. At T2, the JMA data were measured to be 77.5%-145.7% of presurgical values in the experimental group, and 60.3%-90.6% in the control group. At T3, the measurements were 112.2%-179.2% of presurgical values in the experimental group, and 77.6%-157.2% in the control group. The patients in the experimental group exhibited more favorable recovery than did those in the control group, from T1 to T2 and T1 to T3. However, after termination of physiotherapy, no significant difference in the extent of recovery was observed between groups up to 6 months after OGS.

    Colorectal cancer is a common malignant neoplasm and its treatment usually involves surgery associated, in some cases, depending on the staging, with chemoradiotherapy. Necrotising fasciitis of the perineum is a highly lethal infection of the perineum, perirectal tissues and genitals, requiring emergency surgical debridement, broad-spectrum antibiotics and control of sepsis. We present the case of a 59-year-old man with necrotising fasciitis of the perineum as the first clinical manifestation of locally advanced adenocarcinoma of the rectum, in which successful management consisted of early and aggressive surgical debridement, followed by multimodal therapy with curative intent. 2 years and 6 months after surgery the patient is well, with no evidence of local or systemic relapse.

    We herein report a case involving a 70-year-old man who was diagnosed with early gastric cancer that occurred after coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA) for effort-induced angina. He was successfully treated by laparoscopic surgery. Preoperative cardiac three-dimensional computed tomography and coronary angiography showed an occlusion of the RGEA graft, which could lead to ligation of the RGEA to dissect the lymph nodes along the RGEA. The laparoscopic approach helps to identify and avoid injury to the RGEA graft because of its enlarged and precise viewing field compared with laparotomy followed by retractor placement. Laparoscopic surgery is a useful method in such cases to reduce perioperative complications risk.

    The study was conducted to evaluate the effect of early physical rehabilitation by comparing the differences of surface electromyographic (sEMG) activity in the masseter and anterior temporalis muscles after surgical correction of skeletal class III malocclusion. The prospective study included 63 patients; the experimental groups contained 31 patients who received early systematic physical rehabilitation; the control group (32 patients) did not receive physiotherapy. The amplitude of sEMG in the masticatory muscles reached 72.6-121.3% and 37.5-64.6% of pre-surgical values in the experimental and control groups respectively at 6 weeks after orthognathic surgery (OGS). At 6 months after OGS, the sEMG reached 135.1-233.4% and 89.6-122.5% of pre-surgical values in the experimental and control groups respectively. Most variables in the sEMG examination indicated that recovery of the masticatory muscles in the experimental group was better than the control group as estimated in the early phase (T1 to T2) and the total phase (T1 to T3); there were no significant differences between the mean recovery percentages in the later phase (T2 to T3). Early physical rehabilitative therapy is helpful for early recovery of muscle activity in masticatory muscles after OGS. After termination of physical therapy, no significant difference in recovery was indicated in patients with or without early physiotherapy.

    Vulvar carcinomas (VC) and vulvar in situ cancers (VCIS) are rare genital malignancies. Total vulvectomy as the standard of care has been replaced by local excision during the early stages of the disease. We studied whether conservation of the clitoris in vulvar surgery has a positive effect on either the quality of life (QoL) or the sexual sensation of the patient. In a retrospective study, patients with and without clitoris-sparing surgery were interviewed using the Female Sexual Function Index questionnaire (FSFI) and the Short Form 12(®) questionnaire (SF-12). The frequencies of high and low levels and the medians were compared using the Cox-Mantel, Chi(2) and Fisher's exact tests. We identified 24 patients who had surgery in our department for VCIS or VC stage I/II, between 2006 and 2008. Ten of these patients required total inguinal lymphadenectomies and another five required sentinel node biopsies. In twelve patients, the clitoris had been spared, whereas in the remaining twelve, the clitoris had needed to be removed. These groups did not differ in terms of tumor size, stage, type of surgery or age of the patients. The evaluation of the SF-12 indicated high satisfaction in the physical scores for 33% of patients with clitoris-sparing surgery vs. 67% after clitoris resection (n.s.). For the mental domain, the rates were 58% and 67% (n.s.), respectively. In the FSFI, both groups showed comparable values 18 (n = 5) in sexual sensation. Reducing the surgical resection is oncologically acceptable, but improvement in the patients' quality of life or sexual sensation is not achieved solely by conserving the clitoris.

    Background Standard superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery is an effective treatment for moyamoya disease, but recent evidence suggests that postoperative cerebral hyperperfusion can occur. In this study, the trendline of changes in regional cerebral blood flow (rCBF) after surgery were continually monitored near the site of anastomosis in order to investigate both the efficacy of the procedure for improving rCBF and the possible riskof hyperperfusion.Methods Standard STA-MCA bypass surgery was performed on 13 patients, rCBF was measured continually using laser Doppler flowmetry (LDF) until the 5th day after the operation with the LDF probe implanted adjacent to the area of the anastomosis. The trendline of rCBF changes postoperatively was recorded for the analysis performed using SPSS 13.0.Results The baseline LDF value of cortical rCBF was (84.68±14.39) perfusion unit (PU), which was linear relative to absolute perfusion volume before anastomosis and (88.90±11.26) PU immediately after anastomosis (P >0.05). The value changed significantly from before to after anastomosis (P 0.05).Conclusions STA-MCA anastomosis improves the cerebral blood supply significantly in the early stage after surgery,however, the risk of symptomatic hyperperfusion may exist, which may possibly occur on the 1st day and 5th day after surgery. A LDF is useful for postoperative monitoring for both the efficacy of bypass and possible risk of neurologic deterioration or bleeding from hyperperfusion.

    Purpose: A retrospectivechart review was conducted to determine whether the time interval from breast-conserving surgery to breast irradiation (surgery-radiation therapy interval) in early stage node-negative breast cancer had any detrimental effects on recurrence rates. Methods and Materials: There were 566 patients with T1 to T3, N0 breast cancer treated with breast-conserving surgery and breast irradiation and without adjuvant systemic treatment between 1985 and 1992. The surgery-to-radiation therapy intervals used for analysis were 0 to 8 weeks (201 patients), >8 to 12 weeks (233 patients), >12 to 16 weeks (91 patients), and >16 weeks (41 patients). Kaplan-Meier estimates of time to local recurrence, disease-free survival, distant disease-free survival, cause-specific survival, and overall survival rates were calculated. Results: Median follow-up was 17.4 years. Patients in all 4 time intervals were similar in terms of characteristics and pathologic features. There were no statistically significant differences among the 4 time groups in local recurrence (P=.67) or disease-free survival (P=.82). The local recurrence rates at 5, 10, and 15 years were 4.9%, 11.5%, and 15.0%, respectively. The distant disease relapse rates at 5, 10, and 15 years were 10.6%, 15.4%, and 18.5%, respectively. The disease-free failure rates at 5, 10, and 15 years were 20%, 32.3%, and 39.8%, respectively. Cause-specific survival rates at 5, 10, and 15 years were 92%, 84.6%, and 79.8%, respectively. The overall survival rates at 5, 10, and 15 years were 89.3%, 79.2%, and 66.9%, respectively. Conclusions: Surgery-radiation therapy intervals up to 16 weeks from breast-conserving surgery are not associated with any increased risk of recurrence in early stage node-negative breast cancer. There is a steady local recurrence rate of 1% per year with adjuvant radiation alone.

    Full Text Available Background: To study the effects of listening to a Thai traditional music program on acute pain alleviation among patients during the first 48 hours after open abdominal surgery. Objective: A cross over research design in adult patients’ aged 18-60 years at Siriraj Hospital. Methods: The sample was selected by purposive sampling based on inclusion criteria and assigned into the following two groups by simple random sampling: the group receiving the Thai traditional music program (experimental group and the group receiving routine care (control group. This study employed a cross over design with 44 samples in a private surgical ward at Siriraj Hospital, Bangkok. Pain was assessed before and after the intervention. Data were collected by the following three sets of instruments: 1 the demographic and treatment background form; 2 the Thai Short - Form McGill Pain Questionnaire with the vital sign form and 3 the post abdominal surgery early ambulation form. Results: The patients in the experimental group had lower mean pain descriptor scores, mean present pain intensity scores and mean Visual Analog Scale scores after the Thai traditional music program than before the intervention at 48 hours after abdominal surgery with statistical significance (t = 14.11, t = 17.41 and t = 16.47 (p < .001, respectively. When compared between groups, the patients in the experimental group had lower mean pain descriptor scores, mean present pain intensity scores and mean Visual Analog Scale scores than the control group at 48 hours with statistical significance (F = 138.71, F = 170 and F = 298.97 (p < .001, respectively. Furthermore, on the first and second postoperative days as well as the sum of both days, the experimental group was also found to have better early ambulation mean scores than the control group with statistical significance (F = 10.67, p < .002, F = 41.36, p < .001, F = 44.47, p < .001, respectively.

    The relative stabilities of phases within the two systems monazite-(Ce) - fluorapatite - allanite-(Ce) and xenotime-(Y) - (Y,HREE)-rich fluorapatite - (Y,HREE)-rich epidote have been tested experimentally as a function of pressure and temperature in systems roughly replicating granitic to pelitic composition with high and moderate bulk CaO/Na2O ratios over a wide range of P-T conditions from 200 to 1000 MPa and 450 to 750 °C via four sets of experiments. These included (1) monazite-(Ce), labradorite, sanidine, biotite, muscovite, SiO2, CaF2, and 2 M Ca(OH)2; (2) monazite-(Ce), albite, sanidine, biotite, muscovite, SiO2, CaF2, Na2Si2O5, and H2O; (3) xenotime-(Y), labradorite, sanidine, biotite, muscovite, garnet, SiO2, CaF2, and 2 M Ca(OH)2; and (4) xenotime-(Y), albite, sanidine, biotite, muscovite, garnet, SiO2, CaF2, Na2Si2O5, and H2O. Monazite-(Ce) breakdown was documented in experimental sets (1) and (2). In experimental set (1), the Ca high activity (estimated bulk CaO/Na2O ratio of 13.3) promoted the formation of REE-rich epidote, allanite-(Ce), REE-rich fluorapatite, and fluorcalciobritholite at the expense of monazite-(Ce). In contrast, a bulk CaO/Na2O ratio of ~1.0 in runs in set (2) prevented the formation of REE-rich epidote and allanite-(Ce). The reacted monazite-(Ce) was partially replaced by REE-rich fluorapatite-fluorcalciobritholite in all runs, REE-rich steacyite in experiments at 450 °C, 200-1000 MPa, and 550 °C, 200-600 MPa, and minor cheralite in runs at 650-750 °C, 200-1000 MPa. The experimental results support previous natural observations and thermodynamic modeling of phase equilibria, which demonstrate that an increased CaO bulk content expands the stability field of allanite-(Ce) relative to monazite-(Ce) at higher temperatures indicating that the relative stabilities of monazite-(Ce) and allanite-(Ce) depend on the bulk CaO/Na2O ratio. The experiments also provide new insights into the re-equilibration of monazite-(Ce) via fluid

    OBJECTIVES: Recent studies conclude that cardiac surgery patients are prone to both mortality and morbidity in the weeks after discharge. Complications such as pleural and pericardial effusions may influence physical recovery due to symptoms such as dyspnoea, chest pain and fatigue. Dedicated...... baseline to 30 days after surgery. RESULTS: The mean difference in walking distance after 30 days was 15% (65 ± 22 m) between groups, P = 0.017. No differences were found in the peak expiratory flow or EuroQOL. In patients with pleural effusion, walking distance improved by 22% after thoracentesis (81 ± 42...... m), P cardiac...

    The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911. We conducted a biographical survey of Giovanni Verga and the motivations for his work on pituitary surgery. In addition, a systematic analysis of all original reports and historical documents about these pituitary procedures referenced in Verga's treatise was carried out. Verga's treatise provides a summary of the techniques employed and surgical outcomes for the first 50 attempted procedures of pituitary tumor removal. This monograph is the only scientific source that includes a complete account of the series of 10 pituitary tumors operated on by Sir Victor Horsley in the 1900s. Three major types of surgery were employed: (i) palliative procedures of craniectomy (n = 6); (ii) transcranial approaches to the pituitary gland, either subfrontal or subtemporal (n = 13); and (iii) transphenoidal routes to expose the sella turcica, either using an upper transnasal-transethmoidal approach (n = 19) or a lower sublabial/endonasal-transeptal one (n = 12). An operative mortality rate of 36% (n = 17) was observed in these early series. The pathological nature of the tumors operated on was available in 42 cases. There were 28 adenomas and 15 craniopharyngiomas. Sir Victor Horsley (1857-1916) and the Viennese surgeons Anton von Eiselsberg (1860-1939) and Oskar Hirsch (1877-1965) were the leading European figures in the development

    Takotsubo syndrome, also known as broken-heart syndrome, stress-induced cardiomyopathy or transient apical ballooning syndrome, is a transient disorder characterized by segmental left ventricular failure in the absence of obstructive coronary artery disease. Most cases of Takotsubo syndrome are caused by acute stress that leads to a sudden, temporary weakening of the cardiac musculature. This stress triggers a rise in circulating catecholamine levels that results in acute ventricular dysfunction. In this report, we describe two cases of Takotsubo syndrome in the early postoperative period after bariatric surgery.

    2015-05-01

    Radical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2 cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

    Infective complications are the most significant cause of morbidity associated with elective colorectal surgery. It can sometimes be difficult to differentiate complications from the normal postoperative course. C-reactive protein (CRP) is an acute phase reactant which has been reported to be predictive of postoperative infective complications.

    2001-03-01

    We examined the value of deep sclerectomy combined with phacoemulsification as a surgical technique in the peri- and postoperative phases. Deep sclerectomy with phacoemulsification was carried out in 18 patients. Mean postoperative follow-up was 7.5 weeks. Deep sclerectomy was more difficult to perform than goniotrephination. We observed neither fibrin reaction nor hypotonic dysregulation (intraocular pressure, IOP, < 8 mmHg). Five patients required additional pressure-lowering drugs during postoperative IOP regulation. We consider the low inflammatory response in the early postoperative phase to outweigh the greater surgical difficulty and prolonged surgery time. Further studies must verify whether higher IOP during the early postoperative phase is sufficient for good long-term IOP regulation.

    NY-ESO-1 belongs to the cancer testis antigens (CTA) family, and is identified in a variety of tumors. Certain studies have demonstrated that NY-ESO-1 predicts tumor recurrence and treatment response. No reports are currently available regarding the correlation between NY-ESO-1 and the recurrence of hepatocellular carcinoma (HCC) following surgery. The purpose of the present study was to evaluate the association between NY-ESO-1 and relapse of HCC and to explore the possible mechanisms for this correlation. A total of 120 HCC patients were analyzed for the expression of NY-ESO-1 by immunohistochemistry (IHC). A stable NY-ESO-1 over-expressed HepG2 cell line (ESO-HepG2) was established to determine the biological effects of NY-ESO-1 on cell proliferation, cell cycle and migration by using the xCELLigence DP system, flow cytometry and xCELLigence SP system. NY-ESO-1 was positive in 28 of 120 (23.3%) HCC tumor tissues. NY-ESO-1 was not detectable in adjacent normal liver tissues. A close correlation was found between NY-ESO-1 expression and the recurrence of HCC following surgery (P=0.007). Kaplan-Meier analysis showed a shorter recurrence-free survival (RFS) for patients positive for NY-ESO-1 (log-rank test, P=0.003). The Cox regression model demonstrated that NY-ESO-1 expression was a significant independent predictor for the recurrence of HCC following curative surgery (P=0.022). Compared with HepG2 cells, ESO-HepG2 cells have increased migration but not proliferation ability. In conclusion, NY-ESO-1 expression is associated with worse HCC outcome following surgery, and the mechanism for this finding may be that NY-ESO-1 increases tumor cell migration.

    Full Text Available Background. Patients who undergo high-risk surgery represent a large amount of post-operative ICU-admissions. These patients are at high risk of experiencing postoperative complications. Renal Resistive Index was found to be related with renal dysfunction, hypertension, and posttraumatic hemorrhagic shock, probably due to vasoconstriction. We explored whether Renal Resistive Index (RRI, measured after awakening from general anesthesia, could have any relationship with postoperative complications. Methods. In our observational, stratified dual-center trial, we enrolled patients who underwent general anesthesia for high-risk major surgery. After awakening in recovery room (or during awakening period in subjects submitted to cardiac surgery we measured RRI by echo-color-Doppler method. Primary endpoint was the association of altered RRI (>0.70 and outcome during the first postoperative week. Results. 205 patients were enrolled: 60 (29.3% showed RRI > 0.70. The total rate of adverse event was 27 (18.6% in RRI ≤ 0.7 group and 19 (31.7% in RRI > 0.7 group (P=0.042. Significant correlation between RRI > 0.70 and complications resulted in pneumonia (P=0.016, septic shock (P=0.003, and acute renal failure (P=0.001 subgroups. Patients with RRI > 0.7 showed longer ICU stay (P=0.001 and lasting of mechanical ventilation (P=0.004. These results were confirmed in cardiothoracic surgery subgroup. RRI > 0.7 duplicates triplicates the risk of complications, both in general (OR 2.03 93 95% CI 1.02–4.02, P=0.044 and in cardiothoracic (OR 2.62 95% CI 1.11–6.16, P=0.027 population. Furthermore, we found RRI > 0.70 was associated with a triplicate risk of postoperative septic shock (OR 3.04, CI 95% 1.5–7.01; P=0.002.

    Full Text Available Abstract Background As the long-term efficacy of stereotactic body radiation therapy (SBRT becomes established and other prostate cancer treatment approaches are refined and improved, examination of quality of life (QOL following prostate cancer treatment is critical in driving both patient and clinical treatment decisions. We present the first study to compare QOL after SBRT and radical prostatectomy, with QOL assessed at approximately the same times pre- and post-treatment and using the same validated QOL instrument. Methods Patients with clinically localized prostate cancer were treated with either radical prostatectomy (n = 123 Spanish patients or SBRT (n = 216 American patients. QOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC grouped into urinary, sexual, and bowel domains. For comparison purposes, SBRT EPIC data at baseline, 3 weeks, 5, 11, 24, and 36 months were compared to surgery data at baseline, 1, 6, 12, 24, and 36 months. Differences in patient characteristics between the two groups were assessed using Chi-squared tests for categorical variables and t-tests for continuous variables. Generalized estimating equation (GEE models were constructed for each EPIC scale to account for correlation among repeated measures and used to assess the effect of treatment on QOL. Results The largest differences in QOL occurred in the first 1–6 months after treatment, with larger declines following surgery in urinary and sexual QOL as compared to SBRT, and a larger decline in bowel QOL following SBRT as compared to surgery. Long-term urinary and sexual QOL declines remained clinically significantly lower for surgery patients but not for SBRT patients. Conclusions Overall, these results may have implications for patient and physician clinical decision making which are often influenced by QOL. These differences in sexual, urinary and bowel QOL should be closely considered in selecting the right treatment

    Full Text Available Rehabilitation of the patients with Hip Joint Arthroplasthy is an indispensable part of the functional recovery. The purpose of this report is to track and measure the results of an applied complex rehabilitation program during the early post-surgery period in home setting (13-45 days after surgery and to make a comparative analysis between the recovery results of patients who conducted a comprehensive rehabilitation treatment, and a control group of patients who conducted only early physical therapy and occupational therapy in the hospitalization in the Department of Orthopedics and Traumatology. Methods and materials: 152 patients (107 female and 45 male aged between 22 and 84 with Hip Joint Arthroplasthy due to osteoarthritis or femoral neck fracture participated in the study, divided into two groups, according to postoperative behavior. The rehabilitation program consists of: kinesitherapy (positional therapy, isometric exercises, movement of the artificial hip joint within the allowed volumes, exercises for upper limbs and the healthy lower limb and ergotherapy (ergonomic home environment adjusted to performing the daily activities of life. Patients in the second control group have conducted kinesitherapy and occupational therapy only in the early postoperative period in orthopedic clinic. Results: Locomotion test and DAL test measurements were taken and the results for each patient were stored in a special patient file. Conclusion: Ensuring an ergonomic home environment and independent practice of kinesitherapeutic and ergotherapeutic stimulate the recovery of the patients’ self-reliance significantly improve the psycho-emotional balance and self-respect, and serves as an important basis for the latter stages of rehabilitation.

    Background It is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.Methods We reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2±12.5) years and the mean left ventricular ejection fraction was (57.4±11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1±11.2) months).Results Fifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n=7), aortic valve replacement (n=3), mitral valve replacement (n=3), mitral valve replacement with coronary artery bypass grafting (n=1) and left atrial myxoma resection (n=1). Neoplastic resection consisted of lung cancer resection (n=5). colonic cancer resection (n=3), gallbladder resection (n=1), colonic cancer resection with gallbladder resection (n=1), hysterectomy (n=2), hysterectomy with bilateral salpingo-oophorectomy (n=2) and left ovariectomy (n=1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).Conclusions Simultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality

    Between 1983 and 1987, 1309 women with stage I or II breast cancer underwent mastectomy (n=894) or conservative surgery (CS, n=415). Of these patients, 124 developed an isolated local recurrence (ILR): chest wall, 56 and in-breast, 68. The 10-year actuarial rate of cause-specific survival after treatment for ILR was 52%. On multivariate analysis three independent prognostic factors for the risk of death after ILR were identified: operability of recurrence (operable vs. inoperable, relative risk [RR]: 5.9), age at initial diagnosis (>40 vs. 24 vs. mastectomy) and recurrent tumor grade (1-2 vs. 3) were not independent predictors of survival. In the mastectomy group, single surgical scar recurrence with initial node negative stage predicted good prognosis, and the 10-year survival was 85%. In the CS group, the 10-year survival rate was 88% with new primary tumor and 54% with true recurrence (p=0.01), and the type of salvage surgery (mastectomy vs. repeat complete excision) had no significant impact on survival (p=0.2). The majority (n=44) of CS patients developed mastectomy (n=16). The identified unfavorable prognostic factors are pointers of the forthcoming systemic progression. Patients with < or = 2 cm in-breast recurrence might receive a second CS.

    Full Text Available On the southeastern slope of the Baranec Mount in the Western Tatra Mountains (Slovakia an apatite-rich pegmatite-like segregation was found in the subvertical fault zone cutting metapelitic rocks. Two zones: felsic (F and mafic (M were found, differing in mineral assemblages and consequently in chemistry. Fluorapatite crystals yield a LA-ICP-MS U-Pb age of 328.6 ± 2.4 Ma. A temperature decrease from 634 °C to 454 °C at a pressure around 500 to 400 MPa with oxygen fugacity increasing during crystallization are the possible conditions for formation of the pegmatite-like segregation, while secondary alterations took place in the temperature range of 340 – 320 °C. The Sr-Nd isotope composition of both apatite and whole rock point toward a crustal origin of the dike in question, suggesting partial melting of (P, F, H2O-rich metasedimentary rocks during prolonged decompression of the Tatra Massif. The original partial melt (felsic component was mixed with an external (F, H2O-rich fluid, carrying Fe and Mg fluxed from more mafic metapelites and crystallizing as biotite and epidote in the mafic component of the dyke.

    The impact of early valve surgery (EVS) on the outcome of Staphylococcus aureus (SA) prosthetic valve infective endocarditis (PVIE) is unresolved. The objective of this study was to evaluate the association between EVS, performed within the first 60 days of hospitalization, and outcome of SA PVIE within the International Collaboration on Endocarditis-Prospective Cohort Study. Participants were enrolled between June 2000 and December 2006. Cox proportional hazards modeling that included surgery as a time-dependent covariate and propensity adjustment for likelihood to receive cardiac surgery was used to evaluate the impact of EVS and 1-year all-cause mortality on patients with definite left-sided S. aureus PVIE and no history of injection drug use. EVS was performed in 74 of the 168 (44.3%) patients. One-year mortality was significantly higher among patients with S. aureus PVIE than in patients with non-S. aureus PVIE (48.2% vs 32.9%; P = .003). Staphylococcus aureus PVIE patients who underwent EVS had a significantly lower 1-year mortality rate (33.8% vs 59.1%; P = .001). In multivariate, propensity-adjusted models, EVS was not associated with 1-year mortality (risk ratio, 0.67 [95% confidence interval, .39-1.15]; P = .15). In this prospective, multinational cohort of patients with S. aureus PVIE, EVS was not associated with reduced 1-year mortality. The decision to pursue EVS should be individualized for each patient, based upon infection-specific characteristics rather than solely upon the microbiology of the infection causing PVIE. © The Author 2014.

    Background. The impact of early valve surgery (EVS) on the outcome of Staphylococcus aureus (SA) prosthetic valve infective endocarditis (PVIE) is unresolved. The objective of this study was to evaluate the association between EVS, performed within the first 60 days of hospitalization, and outcome of SA PVIE within the International Collaboration on Endocarditis–Prospective Cohort Study. Methods. Participants were enrolled between June 2000 and December 2006. Cox proportional hazards modeling that included surgery as a time-dependent covariate and propensity adjustment for likelihood to receive cardiac surgery was used to evaluate the impact of EVS and 1-year all-cause mortality on patients with definite left-sided S. aureus PVIE and no history of injection drug use. Results. EVS was performed in 74 of the 168 (44.3%) patients. One-year mortality was significantly higher among patients with S. aureus PVIE than in patients with non–S. aureus PVIE (48.2% vs 32.9%; P = .003). Staphylococcus aureus PVIE patients who underwent EVS had a significantly lower 1-year mortality rate (33.8% vs 59.1%; P = .001). In multivariate, propensity-adjusted models, EVS was not associated with 1-year mortality (risk ratio, 0.67 [95% confidence interval, .39–1.15]; P = .15). Conclusions. In this prospective, multinational cohort of patients with S. aureus PVIE, EVS was not associated with reduced 1-year mortality. The decision to pursue EVS should be individualized for each patient, based upon infection-specific characteristics rather than solely upon the microbiology of the infection causing PVIE.

    Wilhelm Schultze, Professor of Surgery of the Tokyo Medical Academy, wrote "Vortraege der Allgemeine Chirurgie" for the benefit of his students in about 1880. The author examined this book and concluded that it was based upon "Lehrbuch der Chirurgie und Operationslehre" by Prof. Adolf Bardeleben, his teacher at the Charité in Berlin. Schultze's textbook was translated into Japanese and published by G. Yamazaki and U. Ishiguro, his students at the Tokyo Medical Academy, in 1884. This version was widely used as a textbook in many medical schools at that time, as well as S. Sato's translation of "Die Allgemeine Chirurgische Pathologie und Therapie" written by Prof. Theodor Billroth. The author found and introduced two different Japanese versions of Schultze's textbook printed without permission.

    Speckle tracking, when combined with 3-dimensional (3D) left ventricular ejection fraction, might prove to be a more sensitive marker for postoperative ventricular dysfunction. This study investigated early outcomes in a cohort of patients with left ventricular dysfunction undergoing cardiac surgery. Prospective, blinded, observational study. University hospital; single institution. The study comprised 73 adult patients with left ventricular ejection fraction speckle tracking and 3D left ventricular ejection fraction were computed using transesophageal echocardiography. Mean prebypass global longitudinal strain and 3D left ventricle ejection fraction were significantly lower in patients with postoperative low-cardiac-output syndrome compared with patients who did not develop low cardiac output (global longitudinal strain -7.5% v -10.7% and 3D left ventricular ejection fraction 29% v 39%, respectively; p < 0.0001). The cut-off value of global longitudinal strain predicting postoperative low-cardiac-output syndrome was -6%, with 95% sensitivity and 68% specificity; and 3D left ventricular ejection fraction was 19% with 98% sensitivity and 81% specificity. Preoperative left ventricular global longitudinal strain (-6%) and 3D left ventricular ejection fraction (19%) together could act as predictor of postoperative low-cardiac-output states with high sensitivity (99.9%) in patients undergoing cardiac surgery.

    Early colon cancer (ECC) has been defined as a carcinoma with invasion limited to the submucosa regardless of lymph node status and according to the Royal College of Pathologists as TNM stage T1 NX M0. As the potential risk of lymph node metastasis ranges from 6 to 17% and the preoperative assessment of lymph node metastasis is not reliable, the management of ECC is still controversial, varying from endoscopic to radical resection. A meeting on recent advances on the management of colorectal polyps endorsed by the Italian Society of Colorectal Surgery (SICCR) took place in April 2014, in Genoa (Italy). Based on this material the SICCR decided to issue guidelines updating the evidence and to write a position statement paper in order to define the diagnostic and therapeutic strategy for ECC treatment in context of the Italian healthcare system.

    A review of the perioperative management of patients with hip fractures and concomitant therapy with antiplatelet agents, and to analyse the differences in mortality and perioperative bleeding in early surgery (5 days). Platelet aggregation was measured on admission and immediately before surgery in all patients included in the study A total of 175 patients over 65 years old, with low energy hip fracture were randomised into 3 groups: Patients on antiplatelet therapy undergoing early surgery, patients on antiplatelet therapy undergoing delayed surgery, and patients not on antiplatelet therapy undergoing early surgery. The same clinical and laboratory data were collected prospectively up to 12 months for all the patients. The platelet aggregation was determined by a semi-quantitative computerised system based on impedance aggregometry in whole blood. Bleeding, transfusion requirements and analytical results showed no significant differences between groups. More than half (59.8%) of the patients not taking antiplatelet therapy had normal platelet aggregation on admission, while 13.5% of those taking antiplatelet agents did not. Multivariate analysis showed increased mortality at 12 months for the variables, low Barthel index before hip fracture (OR: 0.9-0.9) and number of transfusions (OR: 1.1-1.5). The average lenth of stay was 4.1 days greater in the delayed surgery group. Early surgery for patients receiving antiplatelet therapy has similar clinical outcomes to the delayed, but improves hospital efficiency by reducing the average length of stay. The antiplatelet drug reported by the patient showed low concordance with the determination of the platelet aggregation. Copyright © 2011 SECOT. Published by Elsevier Espana. All rights reserved.

    A substantial proportion of individuals who undergo surgical procedures to relieve spine pain continue to report significant pain and dysfunction after recovery. Psychopathology and patient expectations have been linked to poor results, leading to an increasing reliance on presurgical psychological screening (PPS) as part of the surgical diagnostic process. The original Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and the MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Dahlstrom, 2001) were among the measures most commonly used in PPS evaluations and research. This study focuses on the newest version of the test, the MMPI-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011; Tellegen & Ben-Porath, 2008/2011) as a predictor of outcomes for spine surgery candidates. Using a sample of 172 men and 210 women who underwent a PPS, we examined the ability of MMPI-2-RF scale scores to predict early surgical outcomes independent of other presurgical risk factors identified by other means, as well as patients' presurgical expectations. MMPI-2-RF results accounted for up to 11% of additional variance in measures of early postoperative functioning. MMPI-2-RF scales that assess for emotional/internalizing problems, specifically Demoralization, measures of somatoform dysfunction, and interpersonal problems contributed most to the prediction of diminished outcome. 2015 APA, all rights reserved

    The current standard therapeutic option for early stage breast cancer (EBC) employs a multimodality treatment approach including conservative surgery, radiotherapy, chemotherapy, and hormone therapy. The most common adjuvant radiotherapeutic strategy consists of external beam radiation therapy (EBRT) delivered to the whole breast using 1.8-2 Gy fractions given five times a week, up to a total dose of 45-50 Gy over a period of 5 weeks. In recent years, altered schedules employing larger dose per fraction delivered in fewer treatment sessions over a shorter overall treatment time began to be explored. We herein present clinical data on accelerated hypofractionated adjuvant whole-breast radiotherapy delivered on a daily basis for a total treatment time of 20 fractions. Between February 2005 and June 2009, a total of 463 patients underwent hypofractionated accelerated adjuvant radiation after conservative surgery for early breast cancer (pathological stage pTis, pT1 or pT2, pN0-N1). The basic course of radiotherapy consisted of 45 Gy, to the whole breast in 20 fractions with 2.25 Gy/fraction; an additional daily boost dose of 0.25 Gy was concomitantly delivered, to the lumpectomy cavity, for an additional total dose of 5 Gy. The cumulative nominal dose was 50 Gy. At follow-up, patients were examined at 3 and 6 months after the end of radiotherapy and twice a year afterward. Toxicity was scored according to the Common Terminology Criteria for Adverse Events, using the Radiation Therapy Oncology Group /European Organization for Research and Treatment of Cancer toxicity scale. Cosmetic results were assessed in agreement with the Harvard criteria. All the 463 patients treated with the accelerated hypofractionated adjuvant whole-breast radiotherapy schedule achieved at least 6 months' follow-up and subsequently were considered for the present analysis. With a median follow-up of 27 months, 5-year DFS is 93.1%. Only three patients experienced disease recurrence: two of them

    Surgery of Crohns disease is an important part of the general treatment algorithm. The role of surgery is changing with the development of conservative procedures. The recent years have seen the return to early treatment of patients with Crohns disease. Given the character of the disease and its intestinal symptoms, a specific approach to these patients is necessary, especially regarding the correct choice of surgery. The paper focuses on the luminal damage of the small and large intestine including complications of the disease. We describe the individual indications for a surgical solution, including the choice of anastomosis or multiple / repeated surgeries.

  10. Hyperoxaluria and Bariatric Surgery

    Science.gov (United States)

    Asplin, John R.

    2007-04-01

    Bariatric surgery as a means to treat obesity is becoming increasingly common in the United States. An early form of bariatric surgery, the jejunoileal bypass, had to be abandoned in 1980 due to numerous complications, including hyperoxaluria and kidney stones. Current bariatric procedures have not been systematically evaluated to determine if they cause hyperoxaluria. Presented here are data showing that hyperoxaluria is the major metabolic abnormality in patients with bariatric surgery who form kidney stones. Further studies are needed to assess the prevalence of hyperoxaluria in all patients with bariatric surgery.

  11. Visualization of trace-element zoning in fluorapatite using BSE and CL imaging, and EPMA and μPIXE/μPIGE mapping

    2016-12-01

    In this paper, zonation patterns of trace elements in fluorapatite are discussed that were visualized using four analytical techniques, namely back-scattered electrons (BSE) and cathodoluminescence (CL) imaging, electron probe micro-analysis (EPMA), and micro-proton-induced X-ray/gamma ray emission (μPIXE/μPIGE) mapping. Each method demonstrates the in-grain compositional variations in a slightly different way. Both BSE and CL provide qualitative data, and the internal textures are displayed in most detail. Additionally, CL points to specific elements enriched in certain growth zones. Qualitative EPMA maps show detailed zonation patterns for specific elements (with high spatial resolution), which are in general correspondence with the patterns observed in BSE and CL images. The μPIXE/μPIGE maps are fully quantitative and the detection limits are relatively low compared to EPMA mapping. In present spot measurements μPIXE demonstrates lower detection limits than EPMA, however, the latter could be considerably improved by extending the acquisition times. There is no significant overlap of REE (rare earth elements) peaks in the acquired μPIXE energy spectra, however, when multiple REEs are present with sufficiently high concentrations, peak deconvolution may pose some difficulties. Spatial resolution of μPIXE/μPIGE images is not sufficiently high to reflect minor textural features, which also result from the greater interaction depth of the proton beam. However, major growth zones are distinguishable. Even though each method has their advantages and limitations, when applied together, they provide an almost complete characterization of compositional variability in trace-element-bearing minerals.

  12. Effects of Laser Power Level on Microstructural Properties and Phase Composition of Laser-Clad Fluorapatite/Zirconia Composite Coatings on Ti6Al4V Substrates

    2016-05-01

    Full Text Available Hydroxyapatite (HA is one of the most commonly used materials for the coating of bioceramic titanium (Ti alloys. However, HA has poor mechanical properties and a low bonding strength. Accordingly, the present study replaces HA with a composite coating material consisting of fluorapatite (FA and 20 wt % yttria (3 mol % stabilized zirconia (ZrO2, 3Y-TZP. The FA/ZrO2 coatings are deposited on Ti6Al4V substrates using a Nd:YAG laser cladding system with laser powers and travel speeds of 400 W/200 mm/min, 800 W/400 mm/min, and 1200 W/600 mm/min, respectively. The experimental results show that a significant inter-diffusion of the alloying elements occurs between the coating layer (CL and the transition layer (TL. Consequently, a strong metallurgical bond is formed between them. During the cladding process, the ZrO2 is completely decomposed, while the FA is partially decomposed. As a result, the CLs of all the specimens consist mainly of FA, Ca4(PO42O (TTCP, CaF2, CaZrO3, CaTiO3 and monoclinic phase ZrO2 (m-ZrO2, together with a small amount of θ-Al2O3. As the laser power is increased, CaO, CaCO3 and trace amounts of tetragonal phase ZrO2 (t-ZrO2 also appear. As the laser power increases from 400 to 800 W, the CL hardness also increases as a result of microstructural refinement and densification. However, at the highest laser power of 1200 W, the CL hardness reduces significantly due to the formation of large amounts of relatively soft CaO and CaCO3 phase.

  13. Effectiveness of an early mobilization program on functional capacity after coronary artery bypass surgery: A randomized controlled trial protocol

    2016-12-01

    Full Text Available Background: Muscle atrophy and prolonged inactivity are associated with an increased sensation of fatigue and reduced functional capacity in the postoperative period in patients undergoing coronary artery bypass grafting. Cardiac rehabilitation after hospital discharge is highly recommended and contributes to improvement in functional capacity and quality of life. However, few studies have evaluated the effectiveness of early mobilization protocols during hospitalization on the patterns of physical activity and functional capacity after coronary artery bypass grafting. Objective: To investigate the effectiveness of an early mobilization program on the functional capacity of patients undergoing coronary artery bypass grafting in the short and long term. Methods: This is a prospective, randomized, controlled, single-blind trial protocol that will evaluate 66 consecutive patients undergoing coronary artery bypass grafting. Patients will be randomized into two training groups: the control group (N = 33, which will perform breathing exercises and the intervention group (N = 33, which will perform breathing exercises and aerobic exercises. The groups will receive treatment from first to the seventh postoperative day, twice daily. In the preoperative period, the following outcomes will be assessed: physical activity level (Baecke Questionnaire, Functional Independence Measure, and functional capacity (6-min walking test. Functional capacity will be reassessed after the 7th and 60th postoperative day. Pulmonary complications and length of hospital stay will also be evaluated. Statistical analysis will be calculated using linear mixed models and will be based on intention-to-treat. The level of significance will be set at α = 5%.

    Full Text Available Abstract Background As neurophysiologic tests may not reveal the extent of brachial plexus injury at the early stage, the role of early radiological work-up has become increasingly important. The aim of the study was to evaluate the concordance between the radiological and clinical findings with the intraoperative findings in adult patients with brachial plexus injuries. Methods Seven consecutive male patients (median age 33; range 15-61 with brachial plexus injuries, caused by motor cycle accidents in 5/7 patients, who underwent extensive radiological work-up with magnetic resonance imaging (MRI, computed tomography myelography (CT-M or both were included in this retrospective study. A total of 34 spinal nerve roots were evaluated by neuroradiologists at two different occasions. The degree of agreement between the radiological findings of every individual nerve root and the intraoperative findings was estimated by calculation of kappa coefficient (К-value. Using the operative findings as a gold standard, the accuracy, sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of the clinical findings and the radiological findings were estimated. Results The diagnostic accuracy of radiological findings was 88% compared with 65% for the clinical findings. The concordance between the radiological findings and the intraoperative findings was substantial (К = 0.76 compared with only fair (К = 0.34 for the clinical findings. There were two false positive and two false negative radiological findings (sensitivity and PPV of 0.90; specificity and NPV of 0.87. Conclusions The advanced optimized radiological work-up used showed high reliability and substantial agreement with the intraoperative findings in adult patients with brachial plexus injury.

    2015-01-01

    Full Text Available Background: Postoperative cognitive decline (POCD after coronary artery bypass grafting (CABG is a common problem. Studies show that pentoxifylline administration reduces inflammation induced by cardiopulmonary bypass and brain injury after ischaemia. Hence the perioperative use of pentoxifylline in attenuating POCD was evaluated in the study. Materials and Methods: Eighty patients were divided randomly into two groups from 106 patients scheduled for CABG surgery. The study group was administered pentoxifylline 400 mg twice daily orally from day of admission to 7th day after surgery, whereas the control group patients received placebo. Neurocognitive assessment was assessed by an independent clinical psychologist one day after admission to hospital and again on 7th postoperative day. The data was analyzed and a P < 0.05 was considered significant results. Results: Pentoxifylline-treated group showed no statistically significant difference in animal naming test scores (10.3 ± 2.2 versus 9.4 ± 2.5, P = 0.07, digit symbol substitution test (26.1 ± 7.47 vs 22.2 ± 6.07, P = 0.09 and 8 subtests of Post Graduate Institute-memory scale. The control group had significant POCD as detected by animal naming test (10.5 ± 3.7 versus 8.6 ± 3.9, P = 0.008, digit symbol substitution test (20.2 ± 8.2 versus 14.7 ± 8.9, P = 0.008 and five subtests of memory scale (P = 0.01, 0.04, 0.003, 0.005 and 0.02. The incidence of POCD was 50% in placebo-treated group compared to 22.5% in pentoxifylline group. Conclusions: The perioperative use of pentoxifylline attenuates the early postoperative neurocognitive decline after CABG using cardiopulmonary bypass.

    In this study, we compared the effects of two analgesic regimens on perioperative nitric oxide index (NOx) and the likelihood of subsequent development of chronic postsurgical pain (CPSP) after breast surgery and sought to determine the association among early postoperative pain, NOx, and the likelihood of subsequent development of CPSP. Twenty-nine consecutive ASA I or II patients undergoing breast surgery with axillary clearance were randomly allocated to one of two groups. Patients in group S (n = 15) received a standard intraoperative and postoperative analgesic regimen (morphine sulfate, diclofenac, dextropropoxyphene hydrochloride + acetaminophen prn). Patients in group N (n = 14) received a continuous paravertebral block (for 48 h) and acetaminophen and parecoxib (followed by celecoxib up to 5 days). Visual analog scale pain scores at rest and on arm movement were recorded regularly until the fifth postoperative day. A telephone interview was conducted 10 wk postoperatively. The McGill Pain Questionnaire was used to characterize pain. NOx was estimated preoperatively, at the end of surgery, 30 min and 2, 4, 12, 24, 48 h postoperatively. Twelve (80%) patients in group S and no patient in group N developed CPSP (P = 0.009). Compared with patients with a pain rating index > or =1 (n = 18) 10 wk postoperatively, patients with a pain rating index = 0 (n = 11) had lesser visual analog scale pain scores on movement at each postoperative time point from 30 min until 96 h postoperatively (P < 0.005) and at rest 30 min (0.6 +\\/- 1.5 versus 30.2 +\\/- 26.8; P = 0.004), 4 h (2.3 +\\/- 7.5 versus 19.0 +\\/- 25.8; P = 0.013), 8 h (4.4 +\\/- 10.2 versus 21.4 +\\/- 27.0; P = 0.03) and 12 h (0.7 +\\/- 1.2 versus 15.4 +\\/- 27.0; P = 0.035) postoperatively. NOx values were greater in group N compared with group S 48 h postoperatively (40.6 +\\/- 20.1 versus 26.4 +\\/- 13.5; P = 0.04).

    Full Text Available Achondroplasia was first described in 1878 and is the most common form of human skeletal dysplasia. Spinal manifestations include thoracolumbar kyphosis, foramen magnum, and spinal stenosis. Progressive kyphosis can result in spinal cord compression and paraplegia due to the reduced size of spinal canal. The deficits are typically progressive, presenting as an insidious onset of paresthesia, followed by the inability to walk and then by urinary incontinence. Paraplegia can be the result of direct pressure on the cord by bone or the injury to the anterior spinal vessels by a protruding bone. Surgical treatment consists of posterior instrumentation, fusion with total wide laminectomy at stenosis levels, and anterior interbody support. Pedicle screws are preferred for spinal instrumentation because wires and hooks may induce spinal cord injury due to the narrow spinal canal. Pedicle lengths are significantly shorter, and 20–25 mm long screws are appropriate for lower thoracic and lumbar pedicles in adult achondroplastic There is no information about the appropriate length of screws for the upper thoracic pedicles. Tracheal injury due to inappropriate pedicle screw length is a rare complication. We report an extremely rare case of tracheal tear due to posterior instrumentation and its management in the early postoperative period.

    Il trattamento conservativo dei trauma splenici è ormai il “gold standard” per i bassi gradi di lesione splenica (III grado), mentre è ancora dibattuta la gestione dei traumi splenici severi (IV-V grado). Controversa rimane la gestione dei traumi splenici di III grado, che potrebbero beneficiare del trattamento conservativo, associato o meno ad angioembolizzazione dell’arteria splenica, in centri specializzati ed idonei alla gestione conservativa dei traumi degli organi parenchimatosi. Le ultime linee guida pubblicate dalla “Eastern Association of Surgery of Trauma” risalgono al 2012 e provvedono a dare solo delle raccomandazioni di livello II-III sulla gestioni dei traumi splenici. Il fattore che maggiormente influenza il successo del trattamento conservativo è la selezione dei pazienti che potrebbero beneficiare di tale gestione. Alla luce di ciò, l’obiettivo primario del nostro studio è di identificare i pazienti con lesioni spleniche post-traumatiche, che dovrebbero essere sottoposti a trattamento conservativo; l’obiettivo secondario è di confrontare il decorso clinico e la durata della degenza nei pazienti trattati conservativamente e in quelli sottoposti a splenectomia. Tutti i pazienti con trauma splenico, ricoverati presso l’U.O. di Chirurgia d’Urgenza dell’Azienda Ospedaliera- Universitaria Sant’Anna, Ferrara (Italia) tra Novembre 2010 (anno in cui è stata istituita l’U.O.) e Dicembre 2014, sono stati inclusi nello studio, per un totale di 54 pazienti. Di questi 54 pazienti, 29 (53.7%) sono stati immediatamente sottoposti ad intervento chirurgico di laparotomia esplorativa e splenectomia, mentre 25 (46.3%) sono stati sottoposti a trattamento conservativo. I pazienti sottoposti ad angioembolizzazione sono stati 9 su 25 (36%). Sono stati raccolti dati epidemiologici, dati riguardanti il decorso clinico e le indagini laboratoristiche e radiologiche a cui i pazienti sono stati sottoposti al momento dell’accesso in Pronto

    Acute kidney injury can greatly increase the severity of multiple organ dysfunction syndrome (MODS) and impair patient outcomes. To study the clinical significance of acute kidney injury in patients with MODS in early postoperative period after cardiac surgety and its influence, on the severity of the patient condition and outcomes. The study involved 117 patients aged 57.2 ± 1.2 years. The Group 1, control, included 74 patients with uncomplicated postoperative period; the Group 2--43 patients with MODS, who were divided into the survivors (33 patients, group 2a) and deaths (10 patients, group 2b). In Group 2. thefollowingparaineters were higher--the volume of blood loss by 1.5 times (p = 0,001), the duration of the cardiopulmonary bypass 1.7 times (p 0.001), and aortic clamping 1.6 times (p = 0,001). Group 2a and 2b on these indicators did not differ Average scale Group 2b was 1,3-fold higher than in survivors (p = 0,001). Patients differ in the severity of the central nervous system disorders (the average score of Glasgow Coma Scale survivors was 1.3 times higher P = 0,001) and severity of acute kidney injury On a RIFLE scale patients of group 2a normal data was observed in 12%, the stage of risk in 61%, and damage in 27%. In 50% of the dead was a stage of disease (p = 0.04), the rest--damage. In the dynamics of the group 2b impaired renal and hepatic functions have progressed. By day 3 ASTwas on average 2-fold higher (p = 0.01), ALT (1.9 fold, p = 0,001), alkaline phosphatase 1.5 times (p = 0.001), while the total blood protein below 1.3 times (p = 0.00 1), than in group 2a. Creatinine in patients of Group 2b was 1.4 tunes higher (p = 0,036), urea 1.6 (p = 0.026), u-NGAL 7 times higher (p = 0.001), than in group 2a.

    Highlights: ► Apatites are effective sorbents to remove Cd{sup 2+} and Zn{sup 2+} in multi-component solution. ► Competitive metal sorption reduces the individual amounts of metal ions removed. ► The complexation of metal ions with EDTA inhibits their sorption on apatites. ► XPS proofs the formation of Ca{sup 2+} and Zn{sup 2+}-substituted surface layer by ion exchange. ► Composition of new surface layer on apatite is Ca{sub 8.4−x}Me{sub x}(HPO{sub 4}){sub 1.6}(PO{sub 4}){sub 4.4}(OH){sub 0.4}. -- Abstract: Apatites are suitable sorbent materials for contaminated soil and water remediation because of their low solubility and ability to bind toxic metals into their structure. Whereas in soil/water systems different complexing ligands are present, it is important to examine how these ligands affect apatite metal sorption process. The removal of cadmium (Cd) and zinc (Zn) ions from aqueous solutions by hydroxyapatite (HAP) and fluorapatite (FAP) was investigated by batch experiments with and without EDTA being present in the pH range 4–11. The surface composition of the solid phases was analyzed by X-ray photoelectron spectroscopy (XPS). The surface layer of apatites (AP), according to the (Ca + Cd + Zn):P atomic ratio, remained constant (1.4 ± 0.1) through an ion exchange. The amount of Cd{sup 2+} and Zn{sup 2+} removed increased with increasing pH. The removed amount of Zn{sup 2+} was higher than Cd{sup 2+}. In the Cd–Zn binary system, competitive sorption reduced the individual removed amounts but the total maximum sorption was approximately constant. In the presence of EDTA, Cd{sup 2+} and Zn{sup 2+} removal was reduced because of the formation of [CdEDTA]{sup 2−} and [ZnEDTA]{sup 2−} in solution. XPS revealed an enrichment of AP surface by Cd{sup 2+} and Zn{sup 2+} and formation of new surface solid-solution phase with the general composition Ca{sub 8.4−x}Me{sub x}(HPO{sub 4}){sub 1.6}(PO{sub 4}){sub 4.4}(OH){sub 0.4}.

    To evaluate predictors of early and long-term outcomes of surgical repair of acute Type A aortic dissection. Retrospective single-centre study evaluating patients surgically treated between 1998 and 2013. Clinical follow-up was performed. Complications were classified according to the International Aortic Arch Surgery Study Group recommendations. Statistical analysis included univariate and multivariate analysis of preoperative and operative data. One hundred eighty-five patients were evaluated. The follow-up was complete for 180 patients (97 %). Mean age was 63 years, 82 % had a DeBakey type I aortic dissection, 18 % a type II. Eleven patients (6 %) died intraoperatively, 119 of the remaining (68 %) had postoperative complications. Thirty-day mortality was 21 % (38 patients). Average ICU and hospital stay were 6 and 14 days, respectively. During a mean follow-up time of 6 ± 4 years we observed 44 deaths (31 %). Twenty patients (14 %) needed late thoracic aorta reoperation. Results from the multivariate analysis are as follows. Thirty-day mortality was associated with abdominal pain at presentation (p < 0.01). The incidence of postoperative complications was related to older age at intervention (p < 0.01) and longer cross-clamp time (p < 0.01). Mortality at follow-up was significantly increased by older age at intervention (p < 0.01), with a logarithmic growth after 60 years, female sex (p < 0.01), preoperative limb ischemia (p = 0.02) and DHCA (p < 0.01). The surgical results of type A aortic dissection are affected by age at intervention with a logarithmic increase of late mortality in patients older than 60 years.

    Background The purpose of this study was to analyze the quality of life in terms of sexual and reproductive outcome in patients suffering from early stage cervical cancer, submitted to an excisional cone as fertility-sparing treatment. Methods A multicenter retrospective analysis about specific dimensions of physical, psychological, reproductive and sexual functions after a cold-knife conization plus pelvic laparoscopic lymphadenectomy was conducted at Division of Gynecologic Oncology, Catholic University of the Sacred Heart, Rome-Italy and at Division of Gynecology, European Institute of Oncology, Milan-Italy. The aim of this study was twofold. It aimed to analyze the quality of life in patients submitted to minimally invasive surgery and to compare these data with radical trachelectomy. Results Twenty-three patients with an average age of 30 years decided to participate in this study. After the treatment, all women (100%) had regular menstruation, 7 (30.4%) had increased not invalidating dysmenorrhea; 1 (4.4%) experienced a cervical stenosis; 6 among 10 patients that tried to conceive (60%) obtained one spontaneous pregnancy; 4 more (40%) underwent in vitro fertilization and embryo transfer and only 1 of them (25%) was successful. About sexual assessment, 1 patient (4.4%) had trouble in lubricating, 3 (13%) had anxiety about performance, 6 (26.1%) complained of dyspareunia which was resolved within 3 subsequent months. All patients (100%) obtained a complete psychological and physical recovery. Conclusion This study demonstrated preliminary encouraging data about sexual and reproductive outcome after excisional conization. A comparison with trachelectomy surely needs longer follow-ups, more cases and prospective analyses. PMID:24696793

    To investigate the effect of a simplified prevention bundle with alcohol-based, dual hand hygiene (HH) audit on the incidence of early-onset ventilation-associated pneumonia (VAP). This 3-year, quasi-experimental study with interrupted time-series analysis was conducted in two cardiovascular surgery intensive care units in a medical center. Unaware external HH audit (eHH) performed by non-unit-based observers was a routine task before and after bundle implementation. Based on the realistic ICU settings, we implemented a 3-component bundle, which included: a compulsory education program, a knowing internal HH audit (iHH) performed by unit-based observers, and a standardized oral care (OC) protocol with 0.1% chlorhexidine gluconate. The study periods comprised 4 phases: 12-month pre-implementation phase 1 (eHH+/education-/iHH-/OC-), 3-month run-in phase 2 (eHH+/education+/iHH+/OC+), 15-month implementation phase 3 (eHH+/education+/iHH+/OC+), and 6-month post-implementation phase 4 (eHH+/education-/iHH+/OC-). A total of 2553 ventilator-days were observed. VAP incidences (events/1000 ventilator days) in phase 1-4 were 39.1, 40.5, 15.9, and 20.4, respectively. VAP was significantly reduced by 59% in phase 3 (vs. phase 1, incidence rate ratio [IRR] 0.41, P = 0.002), but rebounded in phase 4. Moreover, VAP incidence was inversely correlated to compliance of OC (r2 = 0.531, P = 0.001) and eHH (r2 = 0.878, P audit provides better improvement in HH practice. Accordingly, we suggest dual HH audit and consistent bundle performance does matter in quality-of-care VAP prevention.

    The erythrocyte sedimentation rate (ESR) and white blood cell (WBC) count are frequently obtained in the work-up of post-operative fever. However, their diagnostic utility depends upon comparison with normative peri-operative trends which have not yet been described. The purpose of this study is to define a range of erythrocyte sedimentation rates and white blood cell counts following spinal instrumentation and fusion in non-infected patients. Seventy-five patients underwent spinal instrumentation and fusion. The erythrocyte sedimentation rate and white blood cell count were recorded pre-operatively, at 3 and 7 days post-operatively, and at 1 and 3 months post-operatively. Both erythrocyte sedimentation rate and white blood cell count trends demonstrated an early peak, followed by a gradual return to normal. Peak erythrocyte sedimentation rates occurred within the first week post-operatively in 98% of patients. Peak white blood cell counts occurred with the first week in 85% of patients. In the absence of infection, the erythrocyte sedimentation rate was abnormally elevated in 78% of patients at 1 month and in 53% of patients at 3 months post-operatively. The white blood cell count was abnormally elevated in only 6% of patients at 1 month post-operatively. Longer surgical time was associated with elevated white cell count at 1 week post-operatively. The fusion of more vertebral levels had a negative relationship with elevated erythrocyte sedimentation rate at 1 week post-operatively. The anterior surgical approach was associated with significantly lower erythrocyte sedimentation rate at 1 month post-operatively and with lower white cell count at 1 week post-operatively. In non-infected spinal fusion surgeries, erythrocyte sedimentation rates are in the abnormal range in 78% of patients at 1 month and in 53% of patients at 3 months post-operatively, suggesting that the erythrocyte sedimentation rate is of limited diagnostic value in the early post

  19. Surgery for childhood epilepsy

    Full Text Available Approximately 60% of all patients with epilepsy suffer from focal epilepsy syndromes. In about 15% of these patients, the seizures are not adequately controlled with antiepileptic drugs; such patients are potential candidates for surgical treatment and the major proportion is in the pediatric group (18 years old or less. Epilepsy surgery in children who have been carefully chosen can result in either seizure freedom or a marked (>90% reduction in seizures in approximately two-thirds of children with intractable seizures. Advances in structural and functional neuroimaging, neurosurgery, and neuroanaesthesia have improved the outcomes of surgery for children with intractable epilepsy. Early surgery improves the quality of life and cognitive and developmental outcome and allows the child to lead a normal life. Surgically remediable epilepsies should be identified early and include temporal lobe epilepsy with hippocampal sclerosis, lesional temporal and extratemporal epilepsy, hemispherical epilepsy, and gelastic epilepsy with hypothalamic hamartoma. These syndromes have both acquired and congenital etiologies and can be treated by resective or disconnective surgery. Palliative procedures are performed in children with diffuse and multifocal epilepsies who are not candidates for resective surgery. The palliative procedures include corpus callosotomy and vagal nerve stimulation while deep brain stimulation in epilepsy is still under evaluation. For children with "surgically remediable epilepsy," surgery should be offered as a procedure of choice rather than as a treatment of last resort.

In this study, the first FTIR spectra of the OH-stretching region from a Martian apatite are presented that show characteristic OH-bands of a F-rich, hydroxyl-bearing apatite. Depending on the method of apatite-formula calculation and whether charge balance is assumed or not, the FTIR-based quantification of the incorporated OH, expressed as wt% H2O, is in variably good agreement with the H2O concentration calculated from electron microprobe data. EMP analyses yielded between 0.35 and 0.54 wt% H2O, and IR data yielded an average H2O content of 0.31 ± 0.03 wt%, consistent with the lower range determined from EMP analyses. The TEM observations implied that the volatiles budget of fluorapatite is magmatic. The water content and the relative volatile ratios calculated for the NWA 2975 magma are similar to those established for other enriched or intermediate shergottites. It is difficult to define the source of enrichment: either Martian wet mantle or crustal assimilation. Comparing the environment of parental magma generation for NWA 2975 with the terrestrial mantle in terms of water content, it displays a composition intermediate between enriched and depleted MORB.

    Respiratory support following postoperative extubation is of major importance to prevent hypoxemia and subsequent respiratory failure and reintubation. High-flow nasal cannula oxygen (HFNC) delivers a flow-dependent positive airway pressure and improves oxygenation by increasing end-expiratory lung volume. Whether application of HFNC may have therapeutic advantages over conventional oxygen therapy for respiratory support in the early postextubation surgical period remains to be established. The Optiflow for prevention of post-extubation hypoxemia after abdominal surgery (OPERA) trial is an investigator-initiated multicenter randomized controlled two-arm trial with assessor-blinded outcome assessment, randomizing 220 patients with intermediate to high risk of pulmonary complications after abdominal surgery to receive HFNC or conventional oxygen therapy following extubation, stratified by the presence of epidural analgesia and center. The primary outcome measure is the percentage of patients with postoperative hypoxemia one hour after tracheal extubation. Secondary outcome measures are postoperative pulmonary complications, need for noninvasive ventilation and intubation for respiratory failure. The OPERA trial is the first randomized controlled study powered to investigate whether early application of HFNC following extubation after abdominal surgery prevents against postoperative hypoxemia and pulmonary complications.

    Given the increasing number of endocrine surgery fellowship graduates, we investigated if expectations and job opportunities changed over time. American Association of Endocrine Surgeons (AAES) fellowship graduates, surgery department chairs, and physician recruiters were surveyed. Univariate analysis was performed with JMP Pro 12 software. We identified 141 graduates from 2008-2015; survey response rate was 72% (n = 101). Compared to earlier graduates, fewer academic opportunities were available for the recent graduates who intended to join them (P = .001). Unlike earlier graduates, recent graduates expected to also perform elective general surgery, which ultimately represented a greater percentage of their practices (both P job offers decreased. Overall, 84% of graduates matched their intended practice type and 98% reported being satisfied. Reponses from graduates, department chairs, and physician recruiters highlighted opportunities to improve mentor involvement, job search strategies, and online job board utilization. The endocrine surgery job market has diversified resulting in more graduates entering nonacademic practices and performing general surgery. This rapid evolution supports future analyses of the job market and opportunities for job creation. Almost every graduate reported job satisfaction, which encourages graduates to consider joining both academic and nonacademic practices equally. Copyright © 2016 Elsevier Inc. All rights reserved.

    To test the predictive value of stairs climbing test for the development of postoperative complications in lung cancer patients with forced expiratory volume in one second (FEV1)stairs climbing with pulse oximetry before the operation with the number of steps climbed and the time to complete the test recorded. Oxygen saturation and pulse rate were measured every 20 steps. Data on postoperative complications including oxygen use, prolonged mechanical ventilation, and early postoperative mortality were collected. Eighty-seven of 101 patients (86%) had at least one postoperative complication. The type of surgery was significantly associated with postoperative complications (25.5% patients with lobectomy had no early postoperative complications), while age, gender, smoking status, postoperative oxygenation, and artificial ventilation were not. There were more postoperative complications in more extensive and serious types of surgery (Pstairs climbing test produced a significant decrease in oxygen saturation (-1%) and increase in pulse rate (by 10/min) for every 20 steps climbed. The stairs climbing test was predictive for postoperative complications only in lobectomy group, with the best predictive parameter being the quotient of oxygen saturation after 40 steps and test duration (positive likelihood ratio [LR], 2.4; 95% confidence interval [CI], 1.71-3.38; negative LR, 0.53; 95% CI, 0.38-0.76). In patients with other types of surgery the only significant predictive parameter for incident severe postoperative complications was the number of days on artificial ventilation (P=0.006). Stairs climbing test should be done in routine clinical practice as a standard test for risk assessment and prediction of the development of postoperative complications in lung cancer patients selected for elective surgery (lobectomy). Comparative to spirometry, it detects serious disorders in oxygen transport that are a baseline for a later development of cardiopulmonary postoperative

    To investigate whether early postoperative aquatic physical therapy is a low-risk and effective form of physical therapy to improve functional outcomes after orthopedic surgery. Databases MEDLINE, CINAHL, AMED, Embase, and PEDro were searched from the earliest date available until October 2011. Additional trials were identified by searching reference lists and citation tracking. Controlled trials evaluating the effects of aquatic physical therapy on adverse events for adults therapy, early aquatic physical therapy does not increase the risk of wound-related adverse events (risk difference=.01, 95% CI -.05 to .07) and results in improved performance of activities of daily living (SMD=.33, 95% CI=.07-.58, I(2)=0%). There were no significant differences in edema (SMD=-.27, 95% CI=-.81 to .27, I(2)=58%) or pain (SMD=-.06, 95% CI=-.50 to .38, I(2)=32%). After orthopedic surgery aquatic physical therapy improves function and does not increase the risk of wound-related adverse events and is as effective as land-based therapy in terms of pain, edema, strength, and range of motion in the early postoperative period.

    The strategy for treating patients with severe asymptomatic carotid artery stenosis and cardiac disease remains unresolved. Staged or combined carotid endarterectomy in these patients offers the potential benefit of decreased neurological morbidity during and after cardiac surgery; however, in high-risk patients with severe coronary artery disease, chronic obstructive pulmonary disease, or renal impairment, the incidence of death and stroke is significantly higher. We report the results of a prospective, single-center study designed to evaluate the feasibility and safety of carotid artery angioplasty and stenting (CAS) before cardiac surgery in neurologically asymptomatic patients. The periprocedural and long-term outcomes of 356 consecutive patients who underwent CAS before cardiac surgery were analyzed. The procedural success rate of CAS was 97.7%. The death and stroke rate from time of CAS to 30 days after cardiac surgery was 4.8% (n=17). The myocardial infarction rate from time of CAS to 30 days after cardiac surgery was 2.0% (n=7), and the combined death, stroke, and myocardial infarction rate was 6.7% (n=24). Distal embolic protection devices were used in 40% of the cases. This large cohort of asymptomatic patients who underwent staged CAS and cardiac surgery experienced a low periprocedural complication rate. The high rate of freedom from death and stroke during the 5 years of follow-up supports the long-term durability of this approach. Our findings suggest that this new strategy may become a valuable alternative in the treatment of patients with combined carotid and cardiac disease.

    Laser surgery provides good exposure with clear operating fields and satisfactory preliminary functional results. In contrast to conventional excision, it was found that matrix metalloproteinases and the tissue inhibitors of metalloproteinases -1 mRNA expression is higher, myofibroblasts appeared and disappeared slower in laser excision wounds. It has been suggested that the better anatomical and functional results achieved following laser cordectomy may be explained by the fact that such procedures result in better, more rapid healing processes to recover vocal cord for early glottic tumors and better. In this paper, the role of photobiomodulation in laser surgery will be discussed by the cultured monolayer normal human skin fibroblast model of the photobiomodulation of marginal irradiation of high intensity laser beam, the photobiomodulation related to the irradiated tissue, the biological information model of photobiomodulation and the animal models of laser surgery. Although high intensity laser beam is so intense that it destroys the irradiated cells or tissue, its marginal irradiation intensity is so low that there is photobiomodulation on non-damage cells to modulate the regeneration of partly damaged tissue so that the surgery of laser of different parameters results in different post-surgical recovery. It was concluded that photobiomodulation might play an important role in the long-term effects of laser surgery, which might be used to design laser surgery.

    2015-12-28

    Gadoxetic acid- or gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) achieves excellent lesion detection and characterization for both hypervascular hepatocellular carcinoma (HCC) in arterial phase imaging and hypovascular early HCC (small well-differentiated HCC of the vaguely nodular type) in hepatobiliary phase imaging, and has become an indispensable imaging modality in the treatment of HCC. Early HCCs have been detected more frequently since the introduction of EOB-MRI into daily clinical practice. Early HCC is known to progress to conventional hypervascular HCC, and many risk factors have been identified for the hypervascularization of early HCC including the diameter of the tumor, presence of fat, and imaging findings of EOB-MRI. The rate of the development of hypervascular HCC was previously reported to be high in patients with chronic liver disease and early HCC. The presence of early HCC is regarded as a predictor for the recurrence of HCC following hepatic resection. On the other hand, although early HCC itself is currently not regarded as a target lesion for hepatic resection, early HCC at high risk of hypervascularity needs to be treated by local ablation therapy. If concomitant early HCC with progressed HCC is at high risk of hypervascularization and the functional liver reserve of a patient is sufficient, its simultaneous treatment at the time of hepatic resection for progressed HCC is recommended. Further studies on larger numbers of patients are needed before this strategy is adopted.

    2011-01-01

    Full Text Available Robotic surgery for the management of gynecologic cancers allows for minimally invasive surgical removal of cancer-bearing organs and tissues using sophisticated surgeon-manipulated, robotic surgical instrumentation. Early on, gynecologic oncologists recognized that minimally invasive surgery was associated with less surgical morbidity and that it shortened postoperative recovery. Now, robotic surgery represents an effective alternative to conventional laparotomy. Since its widespread adoption, minimally invasive surgery has become an option not only for the morbidly obese but for women with gynecologic malignancy where conventional laparotomy has been associated with significant morbidity. As such, this paper considers indications for robotic surgery, reflects on outcomes from initial robotic surgical outcomes data, reviews cost efficacy and implications in surgical training, and discusses new roles for robotic surgery in gynecologic cancer management.

    Full Text Available Abstract Background The design of a randomized multicenter trial is presented on the effectiveness of a prolonged conservative treatment strategy compared with surgery in patients with persisting intense sciatica (lumbosacral radicular syndrome. Methods/design Patients presenting themselves to their general practitioner with disabling sciatica lasting less than twelve weeks are referred to the neurology outpatient department of one of the participating hospitals. After confirmation of the diagnosis and surgical indication MRI scanning is performed. If a distinct disc herniation is discerned which in addition covers the clinically expected site the patient is eligible for randomization. Depending on the outcome of the randomization scheme the patient will either be submitted to prolonged conservative care or surgery. Surgery will be carried out according to the guidelines and between six and twelve weeks after onset of complaints. The experimental therapy consists of a prolonged conservative treatment under supervision of the general practitioner, which may be followed by surgical intervention in case of persisting or progressive disability. The main primary outcome measure is the disease specific disability of daily functioning. Other primary outcome measures are perceived recovery and intensity of legpain. Secondary outcome measures encompass severity of complaints, quality of life, medical consumption, absenteeism, costs and preference. The main research question will be answered at 12 months after randomization. The total follow-up period covers two years. Discussion Evidence is lacking concerning the optimal treatment of lumbar disc induced sciatica. This pragmatic randomized trial, focusses on the 'timing' of intervention, and will contribute to the decision of the general practictioner and neurologist, regarding referral of patients for surgery.

    Surgery has consistently been demonstrated to be the most effective long-term therapy for the treatment of obesity. However, despite excellent outcomes with current procedures, most patients with obesity- and weight-related comorbidities who meet criteria for surgical treatment choose not to pursue surgery out of fear of operative risks and complications or concerns about high costs. Novel minimally invasive procedures and devices may offer alternative solutions for patients who are hesitant to pursue standard surgical approaches. These procedures may be used for primary treatment of obesity, early intervention for patients approaching morbid obesity, temporary management prior to bariatric surgery, or revision of bypass surgery associated with weight regain. Novel bariatric procedures can in general be divided into four categories: endoluminal space-occupying devices, gastric suturing and restrictive devices, absorption-limiting devices, and neural-hormonal modulating devices. Many of these are only approved as short-term interventions, but these devices may be effective for patients desiring low-risk procedures or a transient effect. We will see the expansion of indications and alternatives for metabolic surgery as these techniques gain approval.

    Medicine has experienced greater scientific and technological advances in the last 50 years than in the rest of human history. The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient. The objective of the surgical robot is to correct human deficiencies and improve surgical skills. The capacity of repeating tasks with precision and reproducibility has been the base of the robot´s success. Robotic technology offers objective and measurable advantages: - Improving maneuverability and physical capacity during surgery. - Correcting bad postural habits and tremor. - Allowing depth perception (3D images). - Magnifying strength and movement limits. - Offering a platform for sensors, cameras, and instruments. Endoscopic surgery transformed conceptually the way of practicing surgery. Nevertheless in the last decade, robotic assisted surgery has become the next paradigm of our era.

    The WHO describes health as physical, mental and social well being. Ever since the establishment of plastic surgery aesthetic surgery has been an integral part of this medical specialty. It aims at reconstructing subjective well-being by employing plastic surgical procedures as described in the educational code and regulations for specialists of plastic surgery. This code confirms that plastic surgery comprises cosmetic procedures for the entire body that have to be applied in respect of psychological exploration and selection criteria. A wide variety of opinions resulting from very different motivations shows how difficult it is to differentiate aesthetic surgery as a therapeutic procedure from beauty surgery as a primarily economic service. Jurisdiction, guidelines for professional conduct and ethical codes have tried to solve this question. Regardless of the intention and ability of the health insurances, it has currently been established that the moral and legal evaluation of advertisements for medical procedures depends on their purpose: advertising with the intent of luring patients into cosmetic procedures that do not aim to reconstruct a subjective physical disorder does not comply with a medical indication. If, however, the initiative originates with the patient requesting the amelioration of a subjective disorder of his body, a medical indication can be assumed.

    Full Text Available Introduction & Objective: This study was conducted to evaluate the effect of early clinical exposure on medical students’ attitude toward their preparation for attending clinical setting. Material & Methods: In an interventional before -after study, 52 fourth semester medical students studying at Hamadan University of medical sciences were enrolled in the study. The participants filled out a self-structured questionnaire before and after taking part in a 4 month course in three different wards including: surgery, pediatric and internal wards . The staff’s opinions about the program were also gathered. Result: Mean attitude score increased significantly after taking part in the course in these areas: satisfaction about basic science lessons (P=0.019, understanding social determinants of health (P= 0.03 and understanding clinical thinking and simple clinical skills (P= 0.01. Passing the course did not have any significant effect in communication skills and current semester scores (P.0.05 in both issues. Forty one percent of the academic staff in the mentioned wards believed in the necessity of early clinical exposure in basic science stage, 29.5% denied it's necessity and 29.5% did not express their opinions. Conclusion: It seems that despite the mean score increase of some items, early clinical exposure program doesn’t have any positive effect on the measured items. Therefore, it is recommended to change the medical education program. Sci J Hamadan Univ Med Sci . 2016; 22 (4 :323-330

    Idiopathic varicose veins of the lower limbs are a frequent but benign disorder. Surgery is only a moment in the course of the disease. Although not the only treatment of essential varicose veins, surgery by an experienced team performing crossectomy, stripping by intussusception using a stripper, and phlebectomy gives fully satisfactory results, both to patient and to physician, in over 80% of cases. New techniques were recently developed that, at present, have not confirmed early hopes.

    Proficiency in minimally invasive surgery requires intensive and continuous training, as it is technically challenging for unnatural visual and haptic perceptions. Robotic and computer sciences are producing innovations to augment the surgeon's skills to achieve accuracy and high precision during complex surgery. This article reviews the current use of robotically assisted surgery, focusing on technology as well as main applications in digestive surgery, and future perspectives. The PubMed database was interrogated to retrieve evidence-based data on surgical applications. Internal and external consulting with key opinion leaders, renowned robotics laboratories and robotic platform manufacturers was used to produce state-of-the art business intelligence around robotically assisted surgery. Selected digestive procedures (oesophagectomy, gastric bypass, pancreatic and liver resections, rectal resection for cancer) might benefit from robotic assistance, although the current level of evidence is insufficient to support widespread adoption. The surgical robotic market is growing, and a variety of projects have recently been launched at both academic and corporate levels to develop lightweight, miniaturized surgical robotic prototypes. The magnified view, and improved ergonomics and dexterity offered by robotic platforms, might facilitate the uptake of minimally invasive procedures. Image guidance to complement robotically assisted procedures, through the concepts of augmented reality, could well represent a major revolution to increase safety and deal with difficulties associated with the new minimally invasive approaches. © 2015 BJS Society Ltd.

    Full Text Available Abstract Background Scapula alata (SA is a known complication of breast surgery associated with palsy of the serratus anterior, but it is seldom mentioned. We evaluated the risk factors associated with SA and the relationship of SA with ipsilateral shoulder/arm morbidity in a series of patients enrolled in a trial of post-surgery radiotherapy (RT. Methods The trial randomized women with completely resected stage I-II breast cancer to short-course image-guided RT, versus conventional RT. SA, arm volume and shoulder-arm mobility were measured prior to RT and at one to three months post-RT. Shoulder/arm morbidities were computed as a post-RT percentage change relative to pre-RT measurements. Results Of 119 evaluable patients, 13 (= 10.9% had pre-RT SA. Age younger than 50 years old, a body mass index less than 25 kg/m2, and axillary lymph node dissection were significant risk factors, with odds ratios of 4.8 (P = 0.009, 6.1 (P = 0.016, and 6.1 (P = 0.005, respectively. Randomization group was not significant. At one to three months’ post-RT, mean arm volume increased by 4.1% (P = 0.036 and abduction decreased by 8.6% (P = 0.046 among SA patients, but not among non-SA patients. SA resolved in eight, persisted in five, and appeared in one patient. Conclusion The relationship of SA with lower body mass index suggests that SA might have been underestimated in overweight patients. Despite apparent resolution of SA in most patients, pre-RT SA portended an increased risk of shoulder/arm morbidity. We argue that SA warrants further investigation. Incidentally, the observation of SA occurring after RT in one patient represents the second case of post-RT SA reported in the literature.

  12. Minimally invasive colon resection for malignant colonic conditions is associated with a transient early increase in plasma sVEGFR1 and a decrease in sVEGFR2 levels after surgery.

    Plasma VEGF levels increase after minimally invasive colorectal resection (MICR) and remain elevated for 2-4 weeks. VEGF induces physiologic and pathologic angiogenesis by binding to endothelial cell (EC) bound VEGF-Receptor-1 (VEGFR1) and VEGFR2. Soluble forms of these receptors sequester plasma VEGF, decreasing the amount available to bind to EC-bound receptors. Ramifications of surgery-related plasma VEGF changes partially depend on plasma levels of sVEGFR1 and sVEGFR2. This study assessed perioperative sVEGFR1 and sVEGFR2 levels after MICR in patients with colorectal cancer. Forty-five patients were studied; blood samples were taken from all patients preoperatively (preop) and on postoperative days (POD) 1 and 3; in most a fourth sample was drawn between POD 7-30. Late samples were bundled into two time points: POD 7-13 and POD 14-30. sVEGFR1 and sVEGFR2 levels were measured via ELISA. sVEGFR2 data are reported as mean +/- SD and were assessed with the paired samples t test. sVEGFR1 data were not normally distributed. They are reported as median and 95% confidence interval (CI) and were assessed with the Wilcoxon signed-Rank test (p MICR; sVEGFR2 changes dominate due to their much larger magnitude. The net result is less plasma VEGF bound by soluble receptors and more plasma VEGF available to bind to ECs early after surgery.

This study investigated the esthetic outcomes and overall satisfaction following OS. Somatosensory change is a relatively common complication and its influence...... on the level of satisfaction was studied. The social-networking web site Facebook was used to identify the study population. An online questionnaire was performed using the website SurveyMonkey. In all, 105 (9%) respondents from the Danish Facebook group about OS, called Kaebeoperation (jaw surgery), were...... in beauty than women (P = 0.030). Sixty-four percent replied that their attractiveness had been increased after OS. Eighty-six percent were happy with the results and 89% would recommend the surgery to others in need. No significant differences in esthetic results and satisfaction were seen with regard...

    Modern medicine, which is evidence-based and overly scientific, has forgotten its artistic component, which is very important for surgery in general and for geriatric surgery in particular. The surgeon treating an old patient must be a politician more than a technician, more an artist than a scientist. Like Leonardo da Vinci, he or she must use scientific knowledge with intelligence and sensitivity, transforming the elderly patient's last days of life into a beautiful and harmonious painting and not into something like an atomic power station which, while no doubt useful, is deprived of beauty and sometimes very dangerous.

    Surgery's impact on blood levels of hepatocyte growth factor (HGF), a potent angiogenic factor, is unknown. Preoperative (PreOp) HGF blood levels are elevated in patients with colorectal cancer (CRC) and correlate with disease stage and prognosis. This study's purpose was to determine plasma HGF levels after minimally invasive colorectal resection (MICR) in patients with CRC. Clinical and operative data were collected. Blood samples were obtained in all patients PreOp and on postoperative day (POD) 1 and 3; in some, samples were taken during weeks 2 and 3 after MICR. Late samples were bundled into 7-day time blocks. HGF levels were determined via enzyme-linked immunosorbent assay in duplicate. Student's t test was used to analyze the data (significance, P MICR were studied. Most had right, sigmoid, or left segmental colectomy. The mean plasma HGF level was higher on POD 1 (2417 ± 1476 pg/mL, P MICR for CRC is associated with a 1.9- to 2.3-fold increase in plasma HGF levels during the first 3 PODs after which levels normalize. This transient increase may briefly promote angiogenesis and the growth of residual tumor cells.

    Full Text Available Abstract Background The combination of cytoreductive surgery (CRS and hyperthermic intraperitoneal chemotherapy (HIPEC is a curative treatment option for peritoneal carcinomatosis (PC. There have been few studies on the pulmonary adverse events (AEs affecting patient recovery after this treatment, thus this study investigated these factors. Methods Between January 2005 and December 2006, clinical data on all pulmonary AEs and the recovery progress were reviewed for 76 patients with after CRS and HIPEC. Patients with pulmonary interventions (thoracocenthesis and chest tubes were compared with the non-intervention patients. Two senior radiologists, blinded to the post-operative clinical course, separately graded the occurrence of pulmonary AEs. Results Of the 76 patients, 6 had needed thoracocentesis and another 6 needed chest tubes. There were no differences in post-operative recovery between the intervention and non-intervention groups. The total number of days on mechanical ventilation, the length of stay in the intensive care unit, total length of hospital stay, tumor burden, and an American Society of Anesthesiologists (ASA grade of greater than 2 were correlated with the occurrence of atelectasis and pleural effusion. Extensive atelectasis (grade 3 or higher was seen in six patients, major pleural effusion (grade 3 in seven patients, and signs of heart failure (grade 1–2 in nine patients. Conclusions Clinical and radiological post-operative pulmonary AEs are common after CRS and HIPEC. However, most of the pulmonary AEs did not affect post-operative recovery.

    Objective To examine the safety and applicability of off pump coronary artery bypass surgery (OPCAB) in patients with significant left ventricular dysfunction and to discuss the clinical implications for the surgical methods. Design Retrospective study. Setting Tertiary care university affiliated referral centre. Participants 353 consecutive patients with preoperative left ventricular ejection fraction ⩽ 35% who underwent coronary artery bypass over a three year period. Main outcome measures Postoperative morbidity and mortality. Methods 144 patients operated by OPCAB were compared with 209 patients operated by conventional coronary artery bypass. Multivariate and univariate analyses were performed on the pre‐ and postoperative variables to predict risk factors associated with hospital morbidity and mortality. Results Patients in the OPCAB group were more likely to be women and to have congestive heart failure, chronic obstructive pulmonary disease, hypertension, and diabetes; patients in the on pump group were more likely to have had a recent myocardial infarction and to have more severe angina pectoris and an urgent/emergent status. The groups did not differ significantly in length of stay, major postoperative complication rates, or mortality. Comparison of the impact of the procedures on surgical methods over time showed an increase in the use of OPCAB (13% to 67%), without any impact on morbidity or mortality. Conclusions OPCAB is feasible and applicable for patients with depressed left ventricular function. This high risk group can potentially benefit from the off pump approach. PMID:15994913

    The aims of the current study were to determine whether pre-operative urinary tract infections in patients presenting acutely with neck of femur fractures resulted in a delay to surgery and whether such patients were at increased risk of developing post-operative surgical site infections. A retrospective review of all patients presenting with a neck of femur fracture, at a single centre over a one-year period. The hospital hip fracture database was used as the main source of data. UK University Teaching Hospital. All patients (n = 460) presenting across a single year study period with a confirmed hip fracture. The presence of pre-operative urinary tract infection, the timing of surgical intervention, the occurrence of post-operative surgical site infection and the pathogens identified. A total of 367 patients were operated upon within 24 hours of admission. Urinary infections were the least common cause of delay. A total of 99 patients (21.5%) had pre-operative urinary tract infection. Post-operatively, a total of 57 (12.4%) patients developed a surgical site infection. Among the latter, 31 (54.4%) did not have a pre-operative urinary infection, 23 (40.4%) patients had a pre-operative urinary tract infection, 2 had chronic leg ulcers and one patient had a pre-operative chest infection. Statistically, there was a strong relationship between pre-operative urinary tract infection and the development of post-operative surgical site infection (p-value: 0.0005). The results of our study indicate that pre-operative urinary tract infection has a high prevalence amongst those presenting with neck of femur fractures, and this is a risk factor for the later development of post-operative surgical site infection.

    Spinal fusion surgery for the treatment of adolescent idiopathic scoliosis (AIS) is increasing. Health systems and surgeons are decreasing hospital length of stay (LOS) to decrease costs. The purpose of this study was to review the contribution of an accelerated discharge protocol on the total cost of a single episode of care related to the surgical treatment of AIS at a single institution. A retrospective cost analysis was performed over an 18-month period, from January 2014 through June 2015, before and after the institution of an accelerated discharge program. Patients treated surgically with ICD-9 code 737.30 (Idiopathic Scoliosis) were reviewed. Itemized costs and LOS were analyzed collectively and by surgeon before and after the accelerated discharge protocol. Eighty AIS patients were treated surgically. The accelerated discharge program significantly reduced average LOS from 4.2 days in 2014 to 3.3 days during the first 6 months of 2015 (P≤0.05). There were no increases in complications. There was a 9% decrease in the total average costs per episode of care. A weighted average, a relative average change in costs, and an average cost savings per case were calculated for 12 different categories. Average Surgical Services and Nursing costs decreased during the study period while all other costs increased. The accelerated discharge program did not directly contribute significantly to this decrease in costs. Greatest cost reduction was associated with average bone graft and pedicle screw cost, with an overall 8.5% reduction in pedicle screw use and a 58% reduction in bone graft costs. Intraoperative variables under the direct control of the surgeon contribute much more to cost reduction than an accelerated discharge program for surgically treated AIS patients.

    OBJECTIVES: To describe the profound alterations in host immunity that are produced by major surgery as demonstrated by experimental and clinical studies, and to evaluate the benefits of therapeutic strategies aimed at attenuating perioperative immune dysfunction. DATA SOURCES: A review of the English-language literature was conducted, incorporating searches of the MEDLINE, EMBASE, and Cochrane collaboration databases to identify laboratory and clinical studies investigating the cellular response to surgery. STUDY SELECTION: Original articles and case reports describing immune dysfunction secondary to surgical trauma were included. DATA EXTRACTION: The results were compiled to show outcomes of different studies and were compared. DATA SYNTHESIS: Current evidence indicates that the early systemic inflammatory response syndrome observed after major surgery that is characterized by proinflammatory cytokine release, microcirculatory disturbance, and cell-mediated immune dysfunction is followed by a compensatory anti-inflammatory response syndrome, which predisposes the patient to opportunistic infection, multiple organ dysfunction syndrome, and death. Because there are currently no effective treatment options for multiple organ dysfunction syndrome, measures to prevent its onset should be initiated at an early stage. Accumulating experimental evidence suggests that targeted therapeutic strategies involving immunomodulatory agents such as interferon gamma, granulocyte colony-stimulating factor, the prostaglandin E(2) antagonist, indomethacin, and pentoxifylline may be used for the treatment of systemic inflammatory response syndrome to prevent the onset of multiple organ dysfunction syndrome. CONCLUSIONS: Surgical trauma produces profound immunological dysfunction. Therapeutic strategies directed at restoring immune homeostasis should aim to redress the physiological proinflammatory-anti-inflammatory cell imbalance associated with major surgery.

    The purpose of this report is to increase awareness of intraoperative burns during standard procedures, to discuss their possible causes and warning signs and to provide recommendations for prevention and procedures to follow after their occurrence. A total of 19 patients associated with intraoperative burn accidents were treated surgically and analyzed after a mean follow-up of 5 +/- 3.5 months. Review included retrospective patient chart analysis, clinical examination, and technical device and equipment testing. A total of 15 patients recently underwent cardiac surgery, and 4 pediatric patients recovered after standard surgical procedures. A total of 15 patients had superficial and 4 presented with deep dermal or full-thickness burns. The average injured TBSA was 2.1 +/- 1% (range, 0.5-4%). Delay between primary surgery and consultation of plastic surgeons was 4.5 +/- 3.4 days. A total of 44% required surgery, including débridment, skin grafting or musculocutaneous gluteus maximus flaps, and the remaining patients were treated conservatively. Successful durable soft-tissue coverage of the burn region was achieved in 18 patients, and 1 patient died after a course of pneumonia. Technical analysis demonstrated one malfunctioning electrosurgical device, one incorrect positioned neutral electrode, three incidents occurred after moisture under the negative electrode, eight burns occurred during surgery while fluid or blood created alternate current pathways, five accidents were chemical burns after skin preparation with Betadine solution, and in one case, the cause was not clear. The surgical team should pay more attention to the probability of burns during surgery. Early patient examination and immediate involvement of plastic and burn surgeons may prevent further complications or ease handling after the occurrence.

    Full Text Available When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the whole first part of the duodenum, complete omentectomy, bursectomy, and D2+ lymphadenectomy performed for a pT3pN2pM1 (+ number 13 lymph nodes adenocarcinoma of the antrum. Duodenal stump rupture was managed successfully by end tube duodenostomy, without omental patching, and tube cholangiostomy. Close assessment of clinical, physical, and radiological signs, output volume, and enzyme concentration of the tube duodenostomy, T-tube, and closed suction drain, which was placed near the tube duodenostomy site to drain the leak around the catheter, dictated postoperative management of the external duodenal fistula.

    Purpose: To prospectively evaluate cosmetic outcomes in women treated with accelerated partial breast irradiation using high-dose-rate interstitial brachytherapy for early-stage breast cancer. Methods and Materials: Between 2004 and 2008, 151 patients with early-stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients had stage Tis-T2 tumors of ≤3 cm that were excised with negative margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. Both the patients and the treating radiation oncologist qualitatively rated cosmesis as excellent, good, fair, or poor over time and ascribed a cause for changes in cosmesis. Cosmetic outcome was evaluated quantitatively by percentage of breast retraction assessment (pBRA). Patients also reported their satisfaction with treatment over time. Results: Median follow-up was 55 months. The rates of excellent-to-good cosmesis reported by patients and the treating radiation oncologist were 92% and 97% pretreatment, 91% and 97% at 3 to 4 months' follow-up, 87% and 94% at 2 years, and 92% and 94% at 3 years, respectively. Breast infection and adjuvant chemotherapy were independent predictors of a fair-to-poor cosmetic outcome at 3 years. Compared to pretreatment pBRA (7.35), there was no significant change in pBRA over time. The volume receiving more than 150 Gy (V150) was the only significant predictor of pBRA. The majority of patients (86.6%) were completely satisfied with their treatment. Conclusions: Patients and the treating physician reported a high rate of excellent-to-good cosmetic outcomes at all follow-up time points. Acute breast infection and chemotherapy were associated with worse cosmetic outcomes. Multicatheter interstitial brachytherapy does not significantly change breast size as measured by pBRA.

    Purpose: To prospectively examine quality of life (QOL) of patients with early stage breast cancer treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy. Methods and Materials: Between March 2004 and December 2008, 151 patients with early stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients included those with Tis-T2 tumors measuring ≤3 cm excised with negative surgical margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. QOL was measured using European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, version 3.0, and QLQ-BR23 questionnaires. The QLQ-C30 and QLQ-BR23 questionnaires were evaluated during pretreatment and then at 6 to 8 weeks, 3 to 4 months, 6 to 8 months, and 1 and 2 years after treatment. Results: The median follow-up was 55 months. Breast symptom scores remained stable in the months after treatment, and they significantly improved 6 to 8 months after treatment. Scores for emotional functioning, social functioning, and future perspective showed significant improvement 2 years after treatment. Symptomatic fat necrosis was associated with several changes in QOL, including increased pain, breast symptoms, systemic treatment side effects, dyspnea, and fatigue, as well as decreased role functioning, emotional functioning, and social functioning. Conclusions: HDR multicatheter interstitial brachytherapy was well tolerated, with no significant detrimental effect on measured QOL scales/items through 2 years of follow-up. Compared to pretreatment scores, there was improvement in breast symptoms, emotional functioning, social functioning, and future perspective 2 years after treatment.

    Full Text Available Abstract Background Accelerated hypofractionation is an attractive approach for adjuvant whole breast radiotherapy. In this study we evaluated the adverse effects at least 3 years post an accelerated hypofractionated whole breast radiotherapy schedule. Methods From October 2004 to March 2006, 39 consecutive patients aged over 18 years with pTis, pT1-2, pN0-1 breast adenocarcinoma who underwent conservative surgery were treated with an adjuvant accelerated hypofractionated radiotherapy schedule consisting of 34 Gy in 10 daily fractions over 2 weeks to the whole breast, followed after 1 week by an electron boost dose of 8 Gy in a single fraction to the tumour bed. Skin and lung radiation toxicity was evaluated daily during therapy, once a week for one month after radiotherapy completion, every 3 months for the first year and from then on every six months. In particular lung toxicity was investigated in terms of CT density evaluation, pulmonary functional tests, and clinical and radiological scoring. Paired t-test, Chi-square test and non-parametric Wilcoxon test were performed. Results After a median follow-up of 43 months (range 36-52 months, all the patients are alive and disease-free. None of the patients showed any clinical signs of lung toxicity, no CT-lung toxicity was denoted by radiologist on CT lung images acquired about 1 year post-radiotherapy, no variation of pulmonary density evaluated in terms of normalised Hounsfield numbers was evident. Barely palpable increased density of the treated breast was noted in 9 out of 39 patients (in 2 patients this toxicity was limited to the boost area and teleangectasia (2 limited to the boost area was evident in 2 out of 39 patients. The compliance with the treatment was excellent (100%. Conclusion The radiotherapy schedule investigated in this study (i.e 34 Gy in 3.4 Gy/fr plus boost dose of 8 Gy in single fraction is a feasible and safe treatment and does not lead to adjunctive acute and late

    Purpose: To evaluate the safety, efficacy and biomarkers of short-course proton beam radiation and capecitabine, followed by pancreaticoduodenectomy in a phase 1/2 study in pancreatic ductal adenocarcinoma (PDAC) patients. Methods and Materials: Patients with radiographically resectable, biopsy-proven PDAC were treated with neoadjuvant short-course (2-week) proton-based radiation with capecitabine, followed by surgery and adjuvant gemcitabine. The primary objective was to demonstrate a rate of toxicity grade ≥3 of <20%. Exploratory biomarker studies were performed using surgical specimen tissues and peripheral blood. Results: The phase 2 dose was established at 5 daily doses of 5 GyE. Fifty patients were enrolled, of whom 35 patients were treated in the phase 2 portion. There were no grade 4 or 5 toxicities, and only 2 of 35 patients (4.1%) experienced a grade 3 toxicity event (chest wall pain grade 1, colitis grade 1). Of 48 patients eligible for analysis, 37 underwent pancreaticoduodenectomy. Thirty of 37 (81%) had positive nodes. Locoregional failure occurred in 6 of 37 resected patients (16.2%), and distant recurrence occurred in 35 of 48 patients (72.9%). With median follow-up of 38 months, the median progression-free survival for the entire group was 10 months, and overall survival was 17 months. Biomarker studies showed significant associations between worse survival outcomes and the KRAS point mutation change from glycine to aspartic acid at position 12, stromal CXCR7 expression, and circulating biomarkers CEA, CA19-9, and HGF (all, P<.05). Conclusions: This study met the primary endpoint by showing a rate of 4.1% grade 3 toxicity for neoadjuvant short-course proton-based chemoradiation. Treatment was associated with favorable local control. In exploratory analyses, KRAS{sup G12D} status and high CXCR7 expression and circulating CEA, CA19-9, and HGF levels were associated with poor survival.

  13. European endocrine surgery in the 150-year history of Langenbeck's Archives of Surgery.

    2010-04-01

    Founded in 1861 as a German language scientific forum of exchange for European surgeons, Langenbeck's Archives of Surgery quickly advanced to become the premier journal of thyroid surgery before World War I, serving as a point of crystallization for the emerging discipline of endocrine surgery. During the interwar period and, in particular, in the first decades after World War II, Langenbeck's Archives of Surgery lost its dominant position as an international and European medium of publication of top quality articles in the area of endocrine surgery. Nevertheless, the journal remained the chief publication organ of German language articles in the field of endocrine surgery. After a series of key events, Langenbeck's Archives of Surgery managed to reclaim its former position as the leading European journal of endocrine surgery: (1) the formation of endocrine surgery in the early 1980s as a subdiscipline of general and visceral surgery; (2) the change of the language of publication from German to English in 1998; and (3) the journal's appointment in 2004 as the official organ of publication of the European Society of Endocrine Surgeons. All in all, the 150-year publication record of Langenbeck's Archives of Surgery closely reflects the history of European Endocrine Surgery. Following the path of seminal articles from Billroth, Kocher, and many other surgical luminaries published in the journal more than 100 years ago, Langenbeck's Archives of Surgery today stands out as the principal European journal in the field of endocrine surgery.

    Accelerated hypofractionation (HF) using larger dose per fraction, delivered in fewer fractions over a shorter overall treatment time, is presently a consistent possibility for adjuvant whole breast radiation (WBRT) after breast-conserving surgery for early breast cancer (EBC). Between 2005 and 2008, we submitted 375 consecutive patients to accelerated hypofractionated WBRT after breast-conserving surgery for EBC. The basic course of radiation consisted of 45 Gy in 20 fractions over 4 weeks to the whole breast (2.25 Gy daily) with an additional daily concomitant boost of 0.25 Gy up to 50 Gy to the surgical bed. Overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS) and local control (LC) were assessed. Late toxicity was scored according to the CTCAE v3.0; acute toxicity using the RTOG/EORTC toxicity scale. Cosmesis was assessed comparing treated and untreated breast. Quality of life (QoL) was determined using EORTC QLQ-C30/QLQ-BR23 questionnaires. With a median follow-up of 60 months (range 42-88), 5 years OS, CSS, DFS and LC were 97.6, 99.4, 96.6 and 100 %, respectively. Late skin and subcutaneous toxicity was generally mild, with few events > grade 2 observed. Cosmetic results were excellent in 75.7 % of patients, good in 20 % and fair in 4.3 %. QoL, assessed both through QLQ-C30/QLQ-BR23, was generally favorable, within the functioning and symptoms domains. Our study is another proof of principle that HF WBRT with a concurrent boost dose to the surgical cavity represents a safe and effective postoperative treatment modality with excellent local control and survival, consistent cosmetic results and mild toxicity.

    2016-01-01

    Objective: This study investigated the effectiveness of a specific exercise approach (SEA) or modifiable heel lift (MHL) to improve functional leg length discrepancy (LLD) after total hip arthroplasty (THA). Methods: The study was a randomized controlled trial with a PROBE (prospective, randomized, open, blinded-endpoint) design trial. Patients (n=33) with both functional and perceived LLDs, 1 week after THA, were randomized to the SEA, MHL, or control groups. Patients in the SEA group performed 2 weeks of exercises to improve hip contracture and lumbar scoliosis. Patients in the MHL group used an insole-type heel lift to correct functional LLD. The control group received normal postoperative care, comprising standard rehabilitation after THA. The primary outcomes were functional LLD, measured by a block test, and patient-perceived LLD at 3 weeks after the surgery. Secondary outcomes included the visual analog scale (VAS) for pain, the Timed Up and Go (TUG) test, and the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) at 3 weeks after the surgery. Results: The functional LLDs (mean ± SD) for the SEA (3.3 ± 3.1 mm) and MHL (2.2 ± 2.1 mm) groups were significantly smaller than for the control group (6.4 ± 4.0 mm). The degree of patient-perceived LLD differed significantly between the SEA and the control groups (p=.005). Conclusions: SEA and MHL use, during early post-operative recovery, can produce relevant changes in functional LLD after THA. PMID:28289580

    Bente Holm

    Full Text Available BACKGROUND: By measuring very early changes in muscle strength and functional performance after fast-track total hip arthroplasty (THA, post-operative rehabilitation, introduced soon after surgery, can be designed to specifically target identified deficits. OBJECTIVES: Firstly, to quantify changes (compared to pre-operative values in hip muscle strength, leg-press power, and functional performance in the first week after THA, and secondly, to explore relationships between the muscle strength changes, and changes in hip pain, systemic inflammation, and thigh swelling. DESIGN: Prospective, cohort study. SETTING: Convenience sample of patients receiving a THA at Copenhagen University Hospital, Hvidovre, Denmark, between March and December 2011. PARTICIPANTS: Thirty-five patients (65.9 ± 7.2 years undergoing THA. MAIN OUTCOME MEASURES: Hip muscle strength, leg-press power, performance-based function, and self-reported disability were determined prior to, and 2 and 8 days after, THA (Day 2 and 8, respectively. Hip pain, thigh swelling, and C-Reactive Protein were also determined. RESULTS: Five patients were lost to follow-up. Hip muscle strength and leg press power were substantially reduced at Day 2 (range of reductions: 41-58%, P<0.001, but less pronounced at Day 8 (range of reductions: 23-31%, P<0.017. Self-reported symptoms and function (HOOS: Pain, Symptoms, and ADL improved at Day 8 (P<0.014. Changes in hip pain, C-Reactive Protein, and thigh swelling were not related to the muscle strength and power losses. CONCLUSIONS: Hip muscle strength and leg-press power decreased substantially in the first week after THA - especially at Day 2 - with some recovery at Day 8. The muscle strength loss and power loss were not related to changes in hip pain, systemic inflammation, or thigh swelling. In contrast, self-reported symptoms and function improved. These data on surgery-induced changes in muscle strength may help design impairment-directed, post

    Orbitopalpebral anomalies in mandibulofacial dysostosis (Treacher-Collins syndrome) can be difficult to correct surgically and most authors recommend correction of the malar bone after the age of 8 years. We propose a new, early surgical approach for periorbital defects that involves initial implantation of autologous fat and subperiosteal malar lift with a pedicled upper eyelid flap. We prospectively studied 5 children, 3 of whom had previously had orbital reconstruction. Initial fat graft into the periorbital area was followed by a subperiosteal malar lift with lateral canthopexy, and a pedicled upper eyelid flap if needed. Two surgeons independently assessed the patients' characteristics including scleral show before and after operation, antimongoloid palpebral fissures, canthal dystopia, number 6 cleft (Tessier classification), skin quality, and surgical and ophthalmic complications. Before operation 3 patients had had ophthalmic problems. Postoperative evaluation showed improvements in scleral show, canthal dystopia, and skin quality, and correction of antimongoloid palpebral fissures and subcutaneous number 6 clefts. There were no postoperative complications. The proposed protocol gave satisfactory aesthetic and functional results in children with Treacher-Collins syndrome. We recommend that it is considered for periorbital reconstruction in all patients with a mandibulofacial deformity.

    Burning is the second most common cause of home injuries in Iran that is often the cause of conflicts between children and young adults. Burning can lead to early and late complications that scar and contracture are the most common. Burn waste treatment is done by two methods: excision and then skin graft after the formation of granulation tissue; and excision and graft simultaneously that in this study, these two methods are compared. This was performed as a quasi-experimental analysis and retrospective study on all patients who were hospitalized for burn scar. All patients who have associated with weak eningimmune diseases such as diabetes, acquired immunodeficiency or congenital, taking steroids and patients undergoing chemotherapy etc. are excluded. The method of grafting in patients is primary graft procedure that was compared with patients who are treated using secondary graft. Data collected through review of patients' hospital and clinic chart. The mean burn percentage in the primary repair group was 14.4% and in the delayed repair group was 16.6%, respectively. The incidence of hematoma in both groups was zero. Skin necrosis and graft rejection and infection in the primary repair group was in 3.7% of patients and in the delayed repair group was in 1.2% of cases (P=0.5) CONCLUSION: Based on the findings of this study, no difference was observed between the two methods of excision and primary graft with delayed graft in the incidence of graft rejection. Due to the shorter treatment of primary graft and patient satisfaction and also according to the findings of this study excision and primary graft method seems appropriate method for treating old waste burning.

    Accelerated hypofractionated whole-breast radiotherapy (WBRT) is considered a standard therapeutic option for early breast cancer (EBC) in the postoperative setting after breast conservation (BCS). A boost to the lumpectomy cavity may further increase local control. We herein report on the 10-year results of a series of EBC patients treated after BCS with hypofractionated WBRT with a concomitant photon boost to the surgical bed over 4 weeks. Between 2005 and 2007, 178 EBC patients were treated with a basic course of radiotherapy consisting of 45 Gy to the whole breast in 20 fractions (2.25 Gy daily) with an additional boost dose of 0.25 Gy delivered concomitantly to the lumpectomy cavity, for an additional dose of 5 Gy. Median follow-up period was 117 months. At 10-year, overall, cancer-specific, disease-free survival and local control were 92.2% (95% CI 88.7-93.4%), 99.2% (95% CI 96.7-99.7%), 95.5% (95% CI 91.2-97.2%) and 97.3% (95% CI 94.5-98.9%), respectively. Only eight patients recurred. Four in-breast recurrences, two axillary node relapses and two metastatic localizations were observed. Fourteen patients died during the observation period due to other causes while breast cancer-related deaths were eight. At last follow-up, ≥G2 fibrosis and telangiectasia were seen in 7% and 5% of patients. No major lung and heart toxicities were observed. Cosmetic results were excellent/good in 87.8% of patients and fair/poor in 12.2%. Hypofractionated WBRT with concomitant boost to the lumpectomy cavity after BCS in EBC led to consistent clinical results at 10 years. Hence, it can be considered a valid treatment option in this setting.

    Background A growing number of studies worldwide have advocated the replacement of whole-breast irradiation with accelerated partial breast irradiation using three-dimensional conformal external-beam radiation (APBI-3DCRr) for early-stage breast cancer. But APBI can be only used in selected population of patients with early-staged breast cancer. It is not replacing the whole breast radiotherapy. This study aimed to examine the feasibility and acute normal tissue toxicity of the APBI-3DCRT technique in Chinese female patients who generally have smaller breasts compared to their Western counterparts.Methods From May 2006 to December 2009, a total of 48 Chinese female patients (with early-stage breast cancer who met the inclusion criteria) received APBI-3DCRT after breast-conserving surgery at Sun Yat-sen University Cancer Center. The total dosage from APBI-3DCRT was 34 Gy, delivered in 3.4 Gy per fractions, twice per day at intervals of at least six hours. The radiation dose, volume of the target area and volume of irradiated normal tissues were calculated.Acute toxicity was evaluated according to the Common Toxicity Criteria (CTC) 3.0.Results Among the 48 patients, the planning target volume for evaluation (PTVE) was (90.42±9.26) cm3, the ipsilateral breast volume (IBV) was (421.74±28.53) cm3, and the ratio between the two was (20.74±5.86)%. Evaluation of the dosimetric characteristics of the PTVE revealed excellent dosimetric results in 14 patients and acceptable results in 34 patients. The dose delivered to the PTVE ranged from 93% to 110% of the prescribed dose. The average ratio of the volume of PTVE receiving 95% of the prescription dose (V95) was (99.26±0.37)%. The habituation index (HI) and the conformity index (CI) were 1.08±0.01 and 0.72±0.02, respectively, suggesting good homogeneity and conformity of the dose delivered to the target field. The radiation dose to normal tissues and organs was within the dose limitation.Subjects experienced mild acute

    Full Text Available A total of 42 patients were submitted to a clinical, behavioural and neuropsychological evaluation with the objective of eventual surgical treatment of epilepsy refractory to the usual clinical therapies. Prolonged video-EEG monitoring, MRI hippocampal volume measurement, lateralization of speech and memory using the amobarbital (Wada test were used. Of 18 operated cases, 12 were submitted to temporal lobectomy, with a follow-up of 6-30 months; 8 patients had significant improvement in seizures control; 2 patients had partial improvement in seizure frequency and intensity; 2 patients had no improvement in seizure control. One patient underwent right frontal lobectomy with total remission of seizures and 5 had callosotomy with varying degrees of success. There was no mortality. Morbidity included one subdural hematoma, one transient hemiparesis, one episode of mania, one lobar pneumonia and frequent immediately post-operative muscular tension headaches. These early results indicate good results of temporal lobectomy patients investigated through a non-invasive presurgical evaluation.No total, 42 pacientes foram submetidos a avaliação clínica, comportamental e neuropsicológica com o objetivo de eventual tratamento cirúrgico de epilepsia refratária aos tratamentos clínicos usuais.

    Two randomized trials recently demonstrated that regional nodal irradiation (RNI) could reduce the risk of recurrence in early breast cancer; however, these trials were conducted in the pretrastuzumab era. Whether these results are applicable to human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients treated with anti-HER2-targeted therapy is unknown. This retrospective analysis was performed on patients with node-positive breast cancer who were enrolled in the Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization phase III adjuvant trial and subjected to BCS. The primary objective of the present study was to examine the effect of RNI on disease-free survival (DFS). A multivariable cox regression analysis adjusted for number of positive lymph nodes, tumor size, grade, age, hormone receptors status, presence of macrometastatis, treatment arm, and chemotherapy timing was carried out to investigate the relationship between RNI and DFS. One thousand six hundred sixty-four HER2-positive breast cancer patients were included, of whom 878 (52.8%) had received RNI to the axillary, supraclavicular, and/or internal mammary lymph nodes. Patients in the RNI group had higher nodal burden and more frequently had tumors larger than 2 cm. At a median follow-up of 4.5 years, DFS was 84.3% in the RNI group and 88.3% in the non-RNI group. No differences in regional recurrence (0.9 % vs 0.6 %) or in overall survival (93.6% vs 95.3%) were observed between the two groups. After adjustment in multivariable analysis, there was no statistically significant association between RNI and DFS (hazard ratio = 0.96, 95% confidence interval = 0.71 to 1.29). Our analysis did not demonstrate a DFS benefit of RNI in HER2-positive, node-positive patients treated with adjuvant HER2-targeted therapy. The benefit of RNI in HER2-positive breast cancer needs further testing within randomized clinical trials.

    The history of pediatric plastic surgery is linked to that of paediatrics. Until the early 19th century, there was no children's hospital. Only some operations were performed before the discovery of anesthesia, aseptic and antisepsis: cleft lip repair, amputation for polydactyly. Many operations were described in the 19th century for cleft lip and palate repair, hypospadias, syndactylies. The first operation for protruding ears was performed in 1881. Pediatric plastic surgery is diversified in the 2nd half of the 20th century: cleft lip and palate, burns, craniofacial surgery, hand surgery become separate parts of the speciality.

    2014-01-01

    Bariatric surgery is a popular and effective treatment for severe obesity, but may have negative effects on the skeleton. This review summarizes changes in bone density and bone metabolism from animal and clinical studies of bariatric surgery, with specific attention to Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB), and sleeve gastrectomy (SG). Skeletal imaging artifacts from obesity and weight loss are also considered. Despite challenges in bone density imaging, the preponderance of evidence suggests that bariatric surgery procedures have negative skeletal effects that persist beyond the first year of surgery, and that these effects vary by surgical type. The long-term clinical implications and current clinical recommendations are presented. Further study is required to determine mechanisms of bone loss after bariatric surgery. Although early studies focused on calcium/vitamin D metabolism and mechanical unloading of the skeleton, it seems likely that surgically-induced changes in the hormonal and metabolic profile may be responsible for the skeletal phenotypes observed after bariatric surgery.

    2014-07-01

    Together with the introduction of new orthodontic techniques and minimally invasive surgery protocols, the emergence of modern patient prototypes has given way to novel timing schemes for the handling of dento-maxillofacial deformities. The aim of this study was to define, justify, and systematize the appropriate timing for orthognathic surgery. A retrospective analysis of orthognathic surgery procedures carried out over a 3-year period was performed. Six timing schemes were defined: 'surgery first', 'surgery early', 'surgery late', 'surgery last', 'surgery only', and 'surgery never'. Gender, age at surgery, main motivation for treatment, orthodontic treatment length, and number of orthodontic appointments were evaluated. A total of 362 orthognathic procedures were evaluated. The most common approach was 'surgery late'. While aesthetic improvement was the leading treatment motivation in 'surgery first', 'surgery early', and 'surgery last' cases, occlusal optimization was the chief aim of 'surgery late'. Sleep-disordered breathing was the main indication for treatment in 'surgery only'. Compared to 'surgery late', orthodontic treatment was substantially shorter in 'surgery early' and 'surgery first' cases, but the number of orthodontic appointments was similar. In conclusion, the skilful management of dento-maxillofacial deformities requires a comprehensive analysis of patient-, orthodontist-, and surgeon-specific variables. Each timing approach has well-defined indications, treatment planning considerations, and orthodontic and surgical peculiarities.

    We obtained favorable therapeutic outcome in 12 cases of dysthyroid ophthalmopathy with diplopia. All the patients underwent Lineac irradiation to the retrobulbar tissue totalling 15 to 20 Gy over 10 days. Extraocular muscle surgery was performed 30 days after irradiation. Diplopia at the primary position almost disappeared one day after surgery. An additional surgery was necessary in one case. The interval between onset of diplopia and surgery averaged 6.1 months. Irradiation prior to muscle surgery appeared to be beneficial in allowing an early surgery and in avoiding surgical overcorrection. (author).

Significant impulse to achieve this goal was expected from minimally invasive surgery and, in particular, robotic surgery; however, a real breakthrough has not yet been achieved. Accordingly, the new strategic approach of cognitive surgery is required to optimize the provision of surgical treatment. A full scale integration of all modules utilized in the operating room (OR) into a comprehensive network and the development of systems with technical cognition are needed to upgrade the current technical environment passively controlled by the surgeon into an active collaborative support system (surgery 4.0). Only then can the true potential of minimally invasive surgery and robotic surgery be exploited.

    A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have been shown to decrease operative times significantly. It is expected that with further refinements and development of adjunct technologies, the technique of computer-enhanced endoscopic cardiac surgery will evolve and may prove to be beneficial for many patients. Robotic technology has provided benefits to cardiac surgery. With improved optics and instrumentation, incisions are smaller. The ergometric movements and simulated three-dimensional optics project hand-eye coordination for the surgeon. The placement of the wristlike articulations at the end of the instruments moves the pivoting action to the plane of the mitral annulus. This improves dexterity in tight spaces and allows for ambidextrous suture placement. Sutures can be placed more accurately because of tremor filtration and high-resolution video magnification. Furthermore, the robotic system may have potential as an educational tool. In the near future, surgical vision and training systems might be able to model most surgical procedures through immersive technology. Thus, a "flight simulator" concept emerges where surgeons may be able to practice and perform the operation without a patient. Already, effective curricula for training teams in robotic surgery exist. Nevertheless, certain constraints continue to limit the advancement to a totally endoscopic computer-enhanced mitral valve operation. The current size of the instruments, intrathoracic instrument collisions, and extrathoracic "elbow" conflicts still can limit dexterity. When smaller instruments are developed, these restraints may be resolved. Furthermore, a working port incision is still required for

    Objective To explore the short term and long term effect comparison of breast - conserving surgery and modified radical mastectomy in early breast cancer. Methods The data of 120 cases of early breast cancer who underwent operation were retrospectively analyzed. The patients were divided into modified radical mastectomy group ( n - 52 ) and breast - conserving surgery group ( n - 68 ). Operative effect, 1 year and 5 year survival rate, local recurrence rate, metastasis rate and life quality were compared between two groups. Results Operation time, intra-operative blood loss and hospital stay in breast - conserving surgery were much less than those in modified radical mastectomy ( P 0. 05 ); SF -36 scores of breast - conserving surgery 5 years after operation were much higher than modified radical mastectomy ( P 0.05);术后5年,保乳手术组SF-36各项评分显著高于改良手术组(P<0.05).结论 保乳手术与改良根治术治疗早期乳腺癌疗效确切,但保乳手术对患者损伤小、恢复快,术后患者生活质量高.

    The presence of diplopia is an undesirable result following strabismus surgery. There are a variety of scenarios where diplopia exists prior to strabismus surgery, and, after surgery, has either been alleviated or decreased to a magnitude amenable to prism correction. In other cases, the patient does not experience diplopia prior to the strabismus surgery, but there exists a definite risk of diplopia after the surgery. In the current review, I examine the literature to help determine the incidence of diplopia after strabismus surgery.

    Objective To investigate the changes of the serum level of heart fatty acid binding protein (HFABP) during the perioporatien of open-heart surgery with cardiopulmenary bypass (CPB) and to clinical value in early detection of myocardial injury following open-heart surgery with CPB. Methods Eighteen patients following dato-selective open-heart surgery by CPB were enrolled at admission for the test. Blood samples were collected at 6 time points (T1 : at 8 PM the night before operation, I2: prior to CPB, 13:30min, T4 : 3h, T5: 12h, T6: 24h after aortic decalmping) and determined for serum levels of HFABP、CK-MB and cTnI. The changes of the serum levels of these three markers at different time points were analyzed and compared. Results Compared the serum level of all the markers from T2 to T6 with that at T1, the serum concentration of HFABP elevated obviously at T4, T5 and reached its peak at T4,and then decreased nearly to the normal level at T6; the level of CK-MB increased remarkably at T5、T6 and reached its peak at T5 end was still higher than that at T1 ; level of cTnI ascended clearly at T5 and reached to the peak at T6. There was significant difference of peak time point among these three markers: HFABP peaked much earlier than CK-MB and cTnI. The peak level of HF/ABP has a positive relationship with that of CK-MB, cTnI, and that of ACCT, but not with the dose of dopamine used after operation. Conclusion HFABP, a newly-known biomarker for the detection of myocardial injury following ischemia, is one of suitable biomarkers and superior to CK-MB and cTnI in the early detection of myocardial injury following opon-heart surgery with CPB.%目的 探讨体外循环(CPB)心内直视术围术期血清心型脂肪酸结合蛋白(heart fatty acid binding protein,HFABP)的变化规律和对术后心肌损伤早期检测的临床应用价值.方法 测定18例择期CPB下行心内直视手术的病人术前1 d(T1)、CPB前即刻(T2)、主动脉开放后30 min(T3)、3 h

    Full Text Available De 441 crianças portadoras de cardiopatias congênitas submetidas a intervenções cirúrgicas, 372 (84% foram extubadas em sala cirúrgica, imediatamente após o procedimento baseado em critérios clínicos, saturação cutânea de O2 e pCO2 no ar expirado. As complicações pós-operatórias não apresentaram correlação com o procedimento, observando-se, inclusive, baixo índice de complicações pulmonares. Concluiu-se que a maioria das crianças, incluindo muitas com lesões complexas e hipertensão pulmonar pre-operatoria, podem ser extubadas precocemente com segurança e diminuição das complicações pulmonares secundárias à ventilação mecânica, bem como redução do período de permanência em UTI, e de hospitalização, stress da criança, dos familiares e os custos hospitalares.Of 441 pediatric patients recovering from surgical repair of congenital heart disease, 372 (84% were extubated in the operating room immediately after the procedure, using a clinical criteria, cutaneous pO2 saturation and pCO2 in exchanged air. Postoperative complications were not correlated with the procedure, and less pulmonary complications were observed. We concluded that most of pediatric patients, including many of those with complex lesions and preoperative pulmonary hipertension, can safely be extubated early cardiac surgery with minimization of pulmonary complications secondary to mechanical ventilation as well as reduced length of ICU and hospitalary stay, minimizing children and parents stress and hospitalary cost.

    To the best of our knowledge, this is the first study to evaluate the predictive value of free air (on a plain radiograph) for bowel perforation in a large prospective cohort of surgical patients. All consecutive patients undergoing abdominal surgery between January 2011 and June 2012 were screened for this study. We performed an upright chest radiograph on the second and third postoperative day. Thereafter, additional radiographic evaluations were performed every 2 days until the disappearance of abdominal free air. Of the 648 subjects enrolled in our study, free abdominal air was found in 65 subjects on the first radiographic evaluation (2 days after surgery), 51 on the second (3 days after surgery), three on the third (5 days after surgery), and none on the fourth (7 days after surgery). The presence of free abdominal air was associated with an increased risk of gastrointestinal perforation. The presence of free air was associated with a hazard ratio (HR) of 21.54 (95% CI 9.66-48.01, pSensitivity, specificity, positive predictive value, and negative predictive value were 70, 93, 33, and 98%, respectively, at 2 days after surgery, and similar results were confirmed at 3 days after surgery. We believe that the presence of free air at 3 days after surgery should not be considered a common finding. Here, we demonstrate that the detection of free air has a remarkable predictive value for gastrointestinal perforation, which has been overestimated in previous experience.

  19. Minimally invasive paediatric cardiac surgery.

    2014-01-01

    The concept of minimally invasive surgery for congenital heart disease in paediatric patients is broad, and has the aim of reducing the trauma of the operation at each stage of management. Firstly, in the operating room using minimally invasive incisions, video-assisted thoracoscopic and robotically assisted surgery, hybrid procedures, image-guided intracardiac surgery, and minimally invasive cardiopulmonary bypass strategies. Secondly, in the intensive-care unit with neuroprotection and 'fast-tracking' strategies that involve early extubation, early hospital discharge, and less exposure to transfused blood products. Thirdly, during postoperative mid-term and long-term follow-up by providing the children and their families with adequate support after hospital discharge. Improvement of these strategies relies on the development of new devices, real-time multimodality imaging, aids to instrument navigation, miniaturized and specialized instrumentation, robotic technology, and computer-assisted modelling of flow dynamics and tissue mechanics. In addition, dedicated multidisciplinary co-ordinated teams involving congenital cardiac surgeons, perfusionists, intensivists, anaesthesiologists, cardiologists, nurses, psychologists, and counsellors are needed before, during, and after surgery to go beyond apparent technological and medical limitations with the goal to 'treat more while hurting less'.

  20. Nutritional deficiencies after bariatric surgery.

    Lifestyle intervention programmes often produce insufficient weight loss and poor weight loss maintenance. As a result, an increasing number of patients with obesity and related comorbidities undergo bariatric surgery, which includes approaches such as the adjustable gastric band or the 'divided' Roux-en-Y gastric bypass (RYGB). This Review summarizes the current knowledge on nutrient deficiencies that can develop after bariatric surgery and highlights follow-up and treatment options for bariatric surgery patients who develop a micronutrient deficiency. The major macronutrient deficiency after bariatric surgery is protein malnutrition. Deficiencies in micronutrients, which include trace elements, essential minerals, and water-soluble and fat-soluble vitamins, are common before bariatric surgery and often persist postoperatively, despite universal recommendations on multivitamin and mineral supplements. Other disorders, including small intestinal bacterial overgrowth, can promote micronutrient deficiencies, especially in patients with diabetes mellitus. Recognition of the clinical presentations of micronutrient deficiencies is important, both to enable early intervention and to minimize long-term adverse effects. A major clinical concern is the relationship between vitamin D deficiency and the development of metabolic bone diseases, such as osteoporosis or osteomalacia; metabolic bone diseases may explain the increased risk of hip fracture in patients after RYGB. Further studies are required to determine the optimal levels of nutrient supplementation and whether postoperative laboratory monitoring effectively detects nutrient deficiencies. In the absence of such data, clinicians should inquire about and treat symptoms that suggest nutrient deficiencies.

    Takotsubo cardiomyopathy syndrome, commonly occurring in postmenopausal women, is characterized by transient apical systolic dysfunction in absence of coronary lesions. The cardiomyopathy is often observed after intense stressful events such as a major surgical procedure. A 72-year-old woman symptomatic for dyspnea at rest, chest pain, and peripheral edema successfully underwent surgery for noncoronary sinus aneurysm-right atrium fistula repair. Two days after surgery the patient developed takotsubo syndrome, diagnosed according to the Mayo Clinic criteria. We reviewed the literature on takotsubo cardiomyopathy as a complication of major cardiac surgery procedures. Takotsubo cardiomyopathy is confirmed as a possible early complication of cardiac surgery. Exaggerated sympathetic stimulation may cause massive endogenous catecholamine release. Hypoperfusion during cardiopulmonary bypass, inotropic drugs administration, and postoperative anxiety and pain are all factors generating stress, possible coronary artery spasm and transient cardiomyopathy, clinically simulating acute myocardial infarction. Several clinical features have been described such as acute mitral insufficiency, systolic anterior motion of the anterior mitral valve leaflet, left ventricular outflow tract obstruction, acute cardiac failure, and cardiogenic shock. Intraventricular thrombi and adverse cerebrovascular events may also be possible complications. Rare catastrophic events such as left ventricular free wall rupture and ventricular septal perforation have been also encountered. After cardiac surgery takotsubo cardiomyopathy should be suspected if clinical and instrumental criteria are met, and promptly differentiated from the more frequent acute myocardial infarction. Prognosis may be favorable if appropriate conservative medical treatment is promptly started. © 2015 Wiley Periodicals, Inc.
