Combined effect of Interceed and 5-fluorouracil on delayed adjustable strabismus surgery. (1/37)

AIMS/BACKGROUND: To discover a more reliable method of performing delayed suture adjustment as a basis to investigate whether delayed adjustment actually provides more stable results. In order to prevent the formation of postoperative adhesions and delay the time of adjustment, an animal study was performed to determine the combined effect of physical barriers, Viscoat and Interceed, and a pharmacological agent, 5-fluorouracil (5-FU). METHODS: 38 rabbit eyes were divided into three groups. After recession of the superior rectus muscle (SRM), 5-FU was applied beneath and over the SRM in group 5-FU. Group I-f had Interceed and 5-FU and group I-fv, Interceed, 5-FU, and Viscoat. Delayed adjustment was performed once on each SRM at 1, 2, and 3 weeks postoperatively. The possible length and the necessary force to adjust as well as the degree of adhesions were recorded. RESULTS: 5-FU delayed the adjustment for up to 1 week after surgery in three out of four eyes. Combined use of Interceed and 5-FU could delay the adjustment for up to 1 week after surgery in three out of five eyes. Addition of Viscoat could delay the adjustment for up to 1 week after surgery in four out of five eyes. Adjustment was possible on only one of four eyes thereafter. CONCLUSIONS: Combined use of Interceed, 5-FU, and Viscoat could delay the adjustment in rabbits until 1 week postoperatively.  (+info)

Evidence-based prevention of post-operative adhesions. (2/37)

Despite decades of research, numerous new product ideas and 'carefully considered opinions' of recognized experts, very few products for the prevention of post-operative adhesions have met the requirements for Level 1 evidence of safety and efficacy. Those that have are useable only at laparotomy. Several new liquid products intended for use at laparoscopy are in various stages of development and clinical investigation. Hopefully, some will prove to be both simple to use and efficacious. Even if this occurs, it must be remembered that a reduction in post-operative adhesions does not necessarily produce a better clinical outcome. Our common sense suggests that fewer adhesions should logically result in less pain, more pregnancies, fewer bowel obstructions and less long-term morbidity. We believe that 'fewer adhesions' is a good thing, but we have no controlled human trials to prove this. How much of a reduction in post-operative adhesions is necessary before it is clinically relevant? A single adhesion in the wrong anatomic location may be catastrophic. How do we measure this? Until these and other questions have been answered (if ever), we have nothing more than educated guesses that all these efforts are warranted.  (+info)

Intraspinal oxidised cellulose (Surgicel) causing delayed paraplegia after thoracotomy--a report of three cases. (3/37)

Oxidised regenerated cellulose (Surgicel) is a commonly used haemostatic agent in neurosurgery, thoracic surgery, and orthopaedics. We present three cases of paraplegia after thoracic surgery during which oxidised cellulose had been used during thoracotomy for haemorrhage control, and was later found to have passed through the intervertebral foramen causing spinal cord compression. In all intraspinal and perispinal procedures, the over-liberal use of Surgicel should be avoided, and attempts made to remove all excess Surgicel once adequate haemostasis is obtained.  (+info)

Fibrin sealant improves hemostasis in peripheral vascular surgery: a randomized prospective trial. (4/37)

OBJECTIVE: To evaluate the efficacy and safety of an investigational fibrin sealant (FS) in a randomized prospective, partially blinded, controlled, multicenter trial. SUMMARY BACKGROUND DATA: Upper extremity vascular access surgery using polytetrafluorethylene (PTFE) graft placement for dialysis was chosen as a reproducible, clinically relevant model for evaluating the usefulness of FS. The FS consisted of pooled human fibrinogen (60 mg/mL) and thrombin (500 NIH U/mL). Time to hemostasis was measured, and adverse events were monitored. METHODS: Consenting adult patients (n = 48) undergoing placement of a standard PTFE graft were randomized in a 2:1:1 ratio to the treatment group using FS (ZLB Bioplasma AG, Bern, Switzerland), oxidized regenerated cellulose (Surgicel, Johnson & Johnson, New Brunswick, NJ), or pressure. Patients received heparin (3,000 IU IVP) before placement of vascular clamps. If the treatment was FS, clamps were left in place for 120 seconds after the application of study material to permit polymerization. If treatment was Surgicel, clamps were left in place until the agent had been applied according to manufacturer's instructions. If the treatment was pressure, clamps were released as soon as the investigator was ready to apply compression. Immediately after release of the last clamp, the arterial and venous suture lines were evaluated for bleeding. The time to hemostasis at both the venous and arterial sites was recorded. RESULTS: Significant (P < or =.005) reduction in time to hemostasis was achieved in the FS group. Thirteen (54.2%) patients randomized to FS experienced immediate hemostasis at both suture lines following clamp removal compared to no patients using Surgicel or pressure. Only one patient (7.1%) in the Surgicel group and no patients in the pressure group experienced hemostasis at 120 seconds from clamp removal, compared to 13 (54.2%) patients for FS. Adverse events were comparable in all groups. There were no seroconversions. CONCLUSIONS: FS achieved more rapid hemostasis than traditional techniques in this peripheral vascular procedure. FS use appeared to be safe for this procedure.  (+info)

The use of local agents: bone wax, gelatin, collagen, oxidized cellulose. (5/37)

The use of local agents to achieve hemostasis is an old and complex subject in surgery. Their use is almost mandatory in spinal surgery. The development of new materials in chemical hemostasis is a continuous process that may potentially lead the surgeon to confusion. Moreover, the more commonly used materials have not changed in about 50 years. Using chemical agents to tamponade a hemorrhage is not free of risks. Complications are around the corner and can be due either to mechanical compression or to phlogistic effects secondary to the material used. This paper reviews about 20 animal and clinical published studies with regard to the chemical properties, mechanisms of action, use and complications of local agents.  (+info)

The use of local agents: Surgicel and Surgifoam. (6/37)

There are various electrical, mechanical and chemical methods used to achieve haemostasis in spine surgery. Chemical haemostatic agents are often preferable to bipolar cautery in intraspinal procedures, because these products control bleeding without occluding the vessel lumen and cause no thermal injuries to adjacent structures. A topical haemostat is the often the technique of choice to control bleeding from bone and to diffuse capillary and epidural venous oozing. This paper focuses on technical aspects of the application of absorbable porcine gelatine and regenerated, oxidised cellulose. These haemostats have been used in neurosurgical intraspinal procedures for more than 30 years; however, new application forms like Surgicel fibrillar and Surgifoam powder imply different handling options, which are discussed in this paper.  (+info)

A Stafne's cavity with unusual location in the mandibular anterior area. (7/37)

The typical Stafne's cavity, located on the posterior portion of the mandible, is a relatively uncommon entity. However, when the defect is located in the anterior region of the mandible, it is quite rare, having thus far been described in only 36 cases in the scientific literature. Most of these defects appear in the fifth and sixth decades of life, are localized to the area of the canines and premolars, and have a predilection for males. The inferior dental canal, one of the anatomical-radiographic landmarks that aid in the diagnosis of Stafne's cavity in the posterior region, is rarely present anterior the mental foramen. For this reason, because of its more variable radiographic appearance compared to the posterior defect, its tendency to be superimposed over the apices of the teeth, and the rarity of its localisation to the anterior mandible, it is much more difficult to establish a definitive diagnosis of a Stafne's cavity in this location. It is therefore more likely that a diagnostic error can occur, especially early on. We present a new case in a 68-year-old male in which the diagnosis was serendipitous, and we review in particular the aetiology and pathogenesis, clinical aspects, and differential diagnoses for this condition.  (+info)

Examination of aqueous oxidized cellulose dispersions as a potential drug carrier. I. Preparation and characterization of oxidized cellulose-phenylpropanolamine complexes. (8/37)

Partially neutralized aqueous dispersions of oxidized cellulose (OC) (COOH content 24.2%; degree of neutralization [DN] 0.22-0.44; solid content 14.4% wt/wt), a biocompatible biodegradable polymer, were prepared and their use to entrap an amine drug was demonstrated. Phenylpropanolamine hydrochloride (PPA.HCl) was used as a model drug. OCA-PPA complexes were prepared by adding the drug solution to the OC dispersion. Light microscopy, powder x-ray diffractometry (PXRD), and Fourier-transform infrared (FT-IR) spectroscopy were used to characterize hydrated and dried OC and the OC-PPA complexes. Drug loading and drug-loading efficiency were calculated from high-performance liquid chromatography. Light microscopy revealed the partially neutralized OC to exist as swollen fibers in the dispersion. The degree of swelling increased with increasing DN of the OC. All dispersions, irrespective of DN, showed a pseudo-plastic flow. The drug loading (12.6%-26.7%) and drug-loading efficiency (30%-48%) increased linearly with increasing DN and drug concentration. The PXRD of the OC-PPA complexes showed no diffraction peaks due to PPA, suggesting that the drug exists in the amorphous state. The FT-IR spectra of the complexes revealed the presence of an ionic linkage between OC and PPA. In conclusion, the results show that the aqueous OC dispersions can be used to molecularly entrap amine drugs to produce an OC-drug complex linked via an ionic linkage.  (+info)

Hemostasis in peripheral vascular surgery is made more difficult by the need for direct arterial and arterial graft suturing as well as by systemic anticoagulation to prevent thrombosis during periods of vascular occlusion. Polytetrafluorethylene (PTFE) is one of the most frequently used graft materials for vascular replacement or bypass in the case when no autologous venae are available (1). However, the insufficient elasticity of PTFE and its porosity promote the development of suture hole bleeding (2,3) which can cause considerable loss of blood and prolongation of operations (2).. This study is designed to demonstrate the superiority of Lyostypt® to oxidized cellulose (Surgicel®) for hemostasis of suture hole bleeding in arterial bypass anastomoses after vascular reconstruction. Lyostypt® is an absorbable, wet stable collagen compress made of collagen fibrils of bovine origin. Collagen leads to thrombocyte adhesion and to activation of coagulation factor XII. Therefore collagen is very ...

For topical haemostasis bone wax, and various other topical haemostatic agents (powdered oxidized cellulose in polyethylene glycol wax, oxidized cellulose, gelatine paste, microfibrillar collagen, gelatine sponge soaked in thrombin) are currently in use [19]. Haemostasis is achieve through the physical, mechanical (bone wax, gelatine, oxidized cellulose) and chemical effect (microfibrillar collagen) of these materials [15, 19]. Bone wax is non-absorbable whereas the other haemostatic agents are absorbed within days and weeks. Complications like allergic reactions, infections, granulomas and interference with bone healing have been noticed only rarely after the application of theses materials [15].. Only a few controlled clinical trials exist that compare two or more haemostatic agents [9, 20-27]. Voormolen et al.

Surgicel, an absorbable sheet of oxidized cellulose polyanhydroglucuronic acid polymer, has been used in many surgical fields. Surgicel is used at surgical oozing sites, physically promoting coagulation and producing an artificial clot [1, 2].. Although Surgicel is often left in surgical sites for effective postoperative haemostasis, previous reports have revealed that a swollen Surgicel can compress and obstruct the function of neighbouring organs. Dogan et al. reported a case of paraplegia following left-sided thoracotomy, suggesting that Surgicel may migrate into the vertebral canal and produce haematomas that result in spinal cord compression [1]. Another report has described the complications associated with Surgicel-produced haematomas, including hemiparesis after trigeminal decompression [2].. As in other surgical specialties, several cases of Surgicel-related complications in cardiovascular surgery have been reported [3-5]. A recent report showed that Surgicel caused severe stenosis of a ...
Background: Transjugular intrahepatic portosystemic shunt (TIPS) has become an important and effective interventional procedure in treatment of the complications related to portal hypertension. Although the primary patency of TIPS has been greatly improved due to the clinical application of cover stent-grafts, the long-term patency is still suboptimal. This study was to investigate the feasibility of using magnetic resonance imaging (MRI)-monitored intra-shunt local agent delivery of motexafin gadolinium (MGd) into shunt-vein walls of TIPS. This new technique aimed to ultimately inhibit shuntstenosis of TIPS. Methodology: Human umbilical vein smooth muscle cells (SMCs) were incubated with various concentrations of MGd, and then examed by confocal microscopy and T1-map MRI. In addition, the proliferation of MGd-treated cells was evaluated. For in vivo validation, seventeen pigs underwent TIPS. Before placement of the stent, an MGd/trypan-blue mixture was locally delivered, via a microporous ...
PURPOSE: Tissue adhesion is a well-known postsurgical phenomenon, causing pain, functional obstruction, and difficult reoperative surgery. To overcome these problems, various synthetic and natural polymer membranes have been developed as postoperative tissue adhesion barriers. However, limitation in their use has hindered its actual application. We prepared a hyaluronate membrane (HM) to evaluate its efficacy and safety as an adhesion barrier compared to a commercialized product (Interceed, Ethicon). METHODS: To evaluate the antiadhesion effect, a cecum-abdominal wall abrasion model was adopted in a rabbit. The denuded cecum was covered by Interceed or HM or neither and apposed to the abdominal wall (each, n = 10). Four weeks after surgery, the level of adhesion was graded. Acute and chronic toxicity of the three groups were also evaluated. RESULTS: Blood samples drawn to evaluate acute toxicity at postoperative day 3 and 7 showed no significant difference among the three groups. The grade and ...

A 72-year-old woman with peripheral arterial disease presented with a 5-day history of rest pain of the left lower leg. Nine years earlier, she had undergone left-sided femoropopliteal bypass surgery, with multiple endovascular procedures thereafter. Examination revealed absent popliteal and pedal pulses in the symptomatic leg and an ankle-brachial pressure index of 0.44. Magnetic resonance angiography revealed thrombotic occlusion of the bypass graft and multiple subsequent stenoses (Figure 1). The patient underwent endovascular mechanical thrombectomy of the bypass graft plus angioplasty of the distal bypass anastomosis and popliteal artery using 2 paclitaxel-eluting balloons (In.Pact Admiral, Medtronic, Minneapolis, Minnesota) (Figure 2). ...
Electronic devices are constructed by a method that includes forming a first conductive layer in an opening in a multilayer dielectric structure supported by a substrate, forming a core conductive layer on the first conductive layer, subjecting the core conductive layer to a H2 plasma treatment, and depositing a capping adhesion/barrier layer on the core conductive layer after the H2 plasma treatment. The multilayer dielectric structure provides an insulating layer for around the core conducting layer. The H2 plasma treatment removes unwanted oxide from the surface region of the core conducting layer such that the interface between the core conducting layer and the capping adhesion/barrier is substantially free of oxides.
ClinicalTrials.gov Identifier: NCT02133378 First received: May 6, 2014 Last updated: January 26, 2016. Last verified: January 2016 PURPOSE. A new topical hemostatic agent composed of a specifically-formulated porous collagen matrix, coated on one side with a thin protein bonding layer (known as NHS-PEG) has been reported to be extremely effective, in addition to traditional means, in terminating bleeding during cardiac operations with control rates as high as 97,5%. The investigators compared such hemostatic agent (Hemopatch; Baxter Inc, Deerfield, IL) with traditional optimized hemostasis routine. Following sample size calculation, in a prospective randomized study design, 100 patients will be treated with Hemopatch and 100 patients will receive traditional optimized hemostasis routine (comparison group). To make the two cohorts as comparable as possible enrollment will be restricted to moderately bleeding vascular anastomosis of Dacron grafts to ascending aorta or moderately bleeding ...

This trajectory is clear not only in the overall shape of Pauls Gospel of the Jewish messiah who is Lord, but also, for instance, in the unfolding narrative of Luke-Acts, with the ascension of the messiah as divine ruler at its thematic center (functioning against the backdrop of Daniel 7). As the royal proclamation of this messiah goes out to Israel in Acts 1-12, it culminates in the sudden death of Herod, Israels false king (and local agent of Rome) who arrogates to himself royal and divine titles that rightly belong to Jesus. Acts 13-28 narrate this same royal proclamation as it makes its way to Rome, to another throne where there sits another ruler who makes similar royal pretenses to divinity. Thus Jesus reveals the nature of all truly human rule to be, in the first instance, that of cruciform service-not of Roman identity or divine aspirations, of imperial power or military violence ...
A landscaper was telling me that his chestnuts are being pierced by some type of insect and the egg is being laid inside the chestnut. There is a black dot as if touched by a felt tip pen and the shell is shiny where an unaffected chestnut is dull colored. He believes the pest is laying the egg after the fruit has matured and just before the husk has begun to open. He has gotten the run around fron our local agent. I told him of the great info I have received in the past and he asked me to inquire concerning this problem. Thank you so much. He also stated he has seen the grub and if he puts a lot of them in a bucket, they seem to come out of the chestnut ...
Colorectal cancer is the second leading cause of mortality in the West, and rectal cancer accounts for about 25% of the colon cancers. The concept of total mesothelial excision (TME) was the most important event in surgery for rectal cancer of the last two decades, because even without a curative approach, it reduced local recurrence and extended 5-year survival.

A randomized, open-label, parallel group, multi-center trial comparing TachoSil with comparator was conducted to evaluate TachoSil for the secondary treatment of local bleeding in patients undergoing hepatic surgery.. A total of 114 patients were randomized to treatment with TachoSil and 110 patients were randomized to treatment with comparator. A similar proportion of male patients and female patients were randomly assigned in the trial (53% and 47%, respectively). The mean (SD) age of patients was 58.1 (13.95) years and in both treatment groups approximately 30% of the patients were above 65 years. The majority of patients were White/Caucasian (80%) and the most common ethnicity was non-Hispanic/non-Latino (88%).¶. A larger proportion of patients in the TachoSil treatment group (81%) than in the comparator treatment group (50%) achieved hemostasis within the first three minutes after treatment application. The primary analysis of the proportion of patients who achieved hemostasis within three ...

Hemoperitoneum may occur from an ovarian puncture point after oocyte retrieval. We report a case of massive hemoperitoneum following transvaginal ultrasound-guided oocyte retrieval in a 33-year-old Caucasian woman. The bleeding required emergency laparoscopy because of active bleeding from the ovarian puncture point. Hemostasis was very difficult to achieve, and traditional operative procedures were not efficient. The only way to stop the bleeding was by using an absorbable fibrinogen and thrombin sealant sponge, which was applied around the ovary. During laparoscopy three pints of packed red blood were administered. No specific alteration of screening coagulation tests was found one month later. Hemostasis can be very difficult to achieve with traditional operative procedures. Topical hemostatic agents can be useful to preserve the ovary wherever possible.

MARISSA HOWARD-MCNATT: So Im a surgeon, so I figured this time wed talk about some of our basic surgical principles, lumpectomy and mastectomy. So one thing I wanted to start with is what I like, surgical history. So well go back in time and see how they treated breast cancer in the past. In the past, they really didnt know what to do with it-- were talk talking the 1500s. Ambroise Pare, who talked about local agents put on the breast and Versalius who knew more about circulation. But he talked about actually excising areas in the breast. And then Lorenz Heister talked about resection and he even removed muscle in the ribs. And James Syne talked about wide excision. He actually added something we know is important, which is removing the lymph nodes. But really, breast cancer treatment, the grandfather that we all think of in surgery, the grandfather of surgery, is Halsted. And Halsted came in the era when general anesthesia had started and he came up with the radical mastectomy. It truly ...

We flew with Air Malawi from Harare to Blantyre, £72 for a return ticket -- a single being more expensive! This was to minimise travelling time as time was short (the others left after 8 days). We could have flown to Lilongwe for the same price, with either Air Malawi or Air Zimbabwe, both reasonable carriers. We left for home from Lilongwe, having had open-jaw tickets, available with KLM and BA. Public transport is good between towns but non-existent in national parks. The only international car-hire company operating here is Avis, who do not offer unlimited mileage and have a steep drop-charge for starting in Blantyre and finishing in Lilongwe, although this works out similar to the cost of the mileage. Hence our flight plan. However, shortly before departure for Africa I was able to book an unlimited mileage deal through Soche Tours (fax 00265 620 440, tel 620 777), a reputable local agent. This cost US$610 for a Toyota Corolla for 7 days, including full insurance, taxes and $80 drop-charge; ...

Polyurethane is relatively biocompatible, transparent, colourless, and autoclavable. In the field of ophthalmology, a polyurethane keratoprosthesis was well tolerated by rabbit eyes even 1 year after implantation. Unlike poly(methylmethacrylate) (PMMA), polyurethane is autoclavable; thus, it has been suggested as a potential material for intraocular lenses and keratoprostheses.16 Because of these encouraging results, we believed that polyurethane could be safely used as an extraocular physical barrier to adhesion formation. There have been no previous reports on the use of this material for delayed adjustable strabismus surgery. The ideal drug release devices for our purpose should fulfil the following criteria.22 Firstly, the device should provide a sustained and relatively uniform therapeutic concentration of the drug in a reliable and predictable fashion over an adequate period of time. Secondly, the device should be easily implantable or injectable, but must remain stable and non-migratory ...

Complicated diverticulitis sometimes requires emergency surgery with considerable morbidity [1]. It is classified by severity according to the Hinchey grading scale, where I and II represent contained abscesses, and III and IV are cases with perforated colon and purulent (III) or faecal (IV) leakage [2]. The traditional treatment for the Hinchey III and IV has been open surgery with resection of the affected segment, blind closure of the distal resection line and a diverting colostomy i.e. Hartmanns procedure [3-6]. Another option is resection with primary anastomosis of the colon [3]. A retrospective study at the Sahlgrenska University Hospital, Gothenburg studied all patients (n = 106) admitted and operated for complicated diverticulitis between 2003 and 2008 [7]. Eighteen percent underwent at least one re-operation during their first admission, and the mean length of hospital stay was 17 (1-111) days. Mortality was 6%, not different from similar studies [2, 6]. The number of complications ...

Materials and methods Observational multicentre study (RECORd Project) collects the data of 1055 patients who underwent PN between January 2009 and December 2012 at 19 Italian centres. Cases treated with more than one HA or with HA other than Floseal® or Tachosil® were excluded. A tri-match propensity score analysis was applied to create 3 groups - no HA group, Floseal® group, Tachosil® group - balanced for gender, age, surgical indication (elective/relative vs imperative), clinical stage (cT1a vs cT1b), tumour growth pattern, surgical approach (open vs minimally invasive), surgical technique (standard PN vs simple enucleation), preoperative haemoglobin and preoperative creatinine. The three groups were compared regarding the main intra and ...
FRASER, JAMES DANIEL BAIN, druggist, scientist, and entrepreneur; b. 11 Feb. 1807 in Pictou, N.S., the son of Daniel Fraser, a merchant, and Catherine McKay; m. 20 Dec. 1831 Christiana MacKay, and they had at least seven children; d. 4 May 1869 in Pictou from a "chronic liver disease.". James Daniel Bain Frasers mother was a daughter of Roderick McKay, a blacksmith and one of the last survivors of the Scottish immigrants who arrived at Pictou on the hector in 1773. Part of Frasers early education may have been at Pictou Academy under the tutelage of Thomas McCulloch*. The family apparently moved to Halifax prior to 1812, left again for Pictou in 1818, went to Saint John, N.B., around 1820, and returned to Pictou in 1824. There in June of that year Fraser opened a drug store. Two of his brothers, Robert Grant and Thomas Roderick, were in the same business; a third brother, John, was a professional diver in Europe.. Fraser soon developed diverse business interests. He was the local agent for the ...
