Failure of a new double glove hole detection system in the Emergency Department.

The purpose of this study was to evaluate the performance of a new double glove hole detection system in the Emergency Department. First, the frequency of holes in both gloves of the double glove hole detection system was determined using a watertight test method. Second, the frequency of glove puncture was determined first by searching for the optical color change that occurs with the ingress of fluid in the double glove hole detection system. These same gloves were then removed and also checked for holes by the watertight test method. After removal from the package, no holes were detected in the two gloves of the system using the watertight test method. In 50 consecutive patients, there was no color change in the inner glove indicating glove puncture. When these same gloves were then tested with the watertight test method, 14 of the 50 double glove hole detection systems failed; all 14 outer gloves were punctured, and three of the inner gloves had holes without demonstrable injury to the skin. This double glove hole detection system is not a reliable system to detect holes in relatively dry clinical settings because the ingress of fluid by capillary action between the gloves is necessary to cause a color change in the inner glove that signals the presence of a hole.

Enhancing knot security by heat treatment of knot ears.

Heat treatment of the ears of knotted sutures markedly enhances knot security. Using coated polyester sutures commonly used in arthroscopic surgery, heat treatment of the knot ears allows secure knot construction to be achieved with a two throw granny (1 x 1) or square (1 = 1) knot. A heat source is being designed for secure knot construction in arthroscopic surgery.

Biomechanical performance of examination gloves.

The purpose of this study was to compare the biomechanical performance of new powder-free commercially available synthetic examination gloves to that of commercially available powder-free latex examination gloves. The synthetic gloves were significantly thinner than the latex gloves. Despite the decreased thickness, all three nitrile gloves, as well as the polyvinyl chloride glove, exhibited a greater resistance to glove puncture. The glove donning forces varied considerably among all gloves, and wet donning forces were greater than dry donning forces. Under dry conditions, the donning forces for the synthetic gloves were less than or equal to the forces for the latex gloves. Because of their increased puncture resistance and similar donning forces, synthetic gloves are a safe alternative to latex examination gloves.

Integrity of powder-free examination gloves to bacteriophage penetration.

The purpose of this study was to compare the resistance to viral penetration of powder-free synthetic examination gloves with powder-free latex examination gloves commonly used in hospitals. Because these gloves had no holes, this study examined viral penetration through a membrane. Using a standard bacteriophage penetration model, no bacteriophage penetration was detected through the membrane for any of the gloves tested. The new powder-free nitrile and polyvinyl chloride synthetic examination gloves provided comparable resistance to viral penetration as did the powder-free latex examination gloves.

Biomechanical performance of latex and non-latex double-glove systems.

The purpose of this study was to evaluate ten commercially available latex, powder-free surgical gloves and four commercially available non-latex, powder-free surgical gloves using standardized, reproducible biomechanical parameters that included glove thickness, puncture resistance, and glove donning force. For all gloves tested, with one exception (Neolontrade mark PF), puncture resistance increased for double-gloves as compared to single-gloves. In addition, single-glove thickness was not a reliable determinant of puncture resistance for either latex or non-latex gloves. For the latex gloves, the Ultrafree double and single-gloves exhibited the highest puncture resistance. The glove donning forces for the Biogeltrade mark M and Biogel Sensortrade mark single-gloves were the lowest. In contrast, the Biogel Revealtrade mark and Encoretrade mark Ultra-Thick exhibited the lowest double-glove donning forces. On the basis of these performance tests of latex gloves, the surgeon should consider the Biogel Reveal as well as the Ultrafree gloves for their latex double-glove system. For the non-latex gloves, the Pure Advantage Nitriletrade mark glove had the highest puncture resistance for one layer and two layers of glove material. The thin Pure Advantage Nitrile glove was the most resistant to glove puncture. The Pure Advantage Nitrile glove had low glove donning forces for both single-glove donning configurations and double-glove donning configurations. Consequently, we recommend the Pure Advantage Nitrile glove as the powder-free, non-latex, double-glove system.

Lacrimal canaliculitis.

Lacrimal canaliculitis is an infection of the lacrimal duct system. The classic features of lacrimal canaliculitis are mild to severe swelling of the canaliculus, mucopurulent discharge from the punctum, and a red, pouting punctum. Canaliculotomy with systemic or topical antibiotics is the most appropriate treatment for this disorder.

Trigeminal neuralgia: a diagnostic challenge.

A 38-year-old white woman came to the emergency department complaining of severe, unilateral jaw pain. She had consulted her primary care physician and dentist without achieving the correct diagnosis or significant relief of her symptoms. The emergency physician made the diagnosis of trigeminal neuralgia by obtaining a history of severe paroxysmal ipsilateral facial pain activated by numerous facial stimuli. A light stimulation of the trigger point precipitated the pain. Her pain relief from carbamazepine lent further credence to the diagnosis of trigeminal neuralgia and appropriate referral to a neurosurgeon. Pain relief was ultimately achieved for the last 8 months by a neurectomy of the right infraorbital nerve.

Innovative techniques in arthroscopic meniscal repair.

Advanced techniques for arthroscopic repair of meniscal tears offer new ways to repair the meniscus and reduce the rate of long-term arthrosis. The new all-inside technique reduces complications, morbidity, and surgical time as compared to the inside-out or outside-in methods of repair. Application of biomaterial technology to new implants used for all-inside arthroscopy show early promising clinical results. The purpose of this report is to describe new biomaterials and techniques being used successfully in arthroscopic surgery on the meniscus.

Modern concepts in arthroscopic Bankart repair.

The purpose of this report is to review recent advances in Bankart repair that allow it to be performed arthroscopically. Metallic implants in the form of staples, screws, or rivets were used initially, but problems with loosening of implants has prompted development of alternative devices and techniques. A modified form of the transglenoid suturing technique used in open Bankart repair has been used successfully but is associated with an increased risk of soft tissue complications. The use of absorbable tacks avoids some of the complications associated with this approach, but the ability to advance the capsule to reduce the volume is limited. Recently, the use of suture anchors has been described for arthroscopic Bankart lesion repair. However, the ability of these anchoring systems to advance and reduce the capsular volume is limited, and the arthroscopic techniques are technically demanding. One particularly innovative suture anchor system uses a bioabsorbable suture anchor with an integrated suture passing system. This self-contained implant allows multiple passes with suture through the capsule, followed by attachment to the glenoid with the bioabsorbable anchor. This procedure allows the capsule to be advanced by passing suture through before it is anchored to the glenoid, thereby reducing capsular volume to help restore shoulder stability.

Influence of irrigation solutions on oscillating bone saw blade performance.

The influence of irrigation on bone cutting was determined by measuring the biomechanical performance of a bone cutting saw during irrigation with various solutions. Solutions of 0.9% saline and 10, 20, and 30% poloxamer-188 were used as the irrigant. A 10% solution of poloxamer-188 was judged to be the superior irrigant because it successfully maintained bone temperature at a controlled level without interfering with the rate of bone removal.

Ease of donning commercially available latex examination gloves.

There are a wide variety of latex examination gloves now available for use by health care providers. A prospective randomized trial was completed to quantify the forces required to don a sample of seven cornstarch-lubricated gloves and 13 powder-free latex examination gloves. The data collected was analyzed by a 20 x 2 general factorial ANOVA, as well as two 1-way ANOVAs using a least significance difference post hoc test. Some powder-free gloves can be easily donned with dry or wet hands without tearing with forces comparable to those encountered with powdered gloves. With the advent of these powder-free examination gloves, powdered gloves can now be abandoned, protecting health professionals and patients from the dangers of absorbable dusting powders. Despite the dangers of the absorbable dusting powders and the Food and Drug Administration's requirement for labeling examination glove boxes, some manufacturers of powdered examination gloves do not appropriately label their boxes with a warning to the health professional and patient of the presence of powder.

Sheets, 3-D strands, trimensional (3-D) shapes, and sutures of either reinforced or nonreinforced expanded polytetrafluoroethylene for facial soft-tissue suspension, augmentation, and reconstruction.

Expanded polytetrafluoroethylene (e-PTFE) is an expanded, fibrillated polymer recently used in facial reconstruction. This material is produced in two compositions: pure e-PTFE, for sheets, 3-D strands, and sutures; and e-PTFE reinforced with fluorinated ethylene propylene (FEP) for sheets and trimensional (3-D) shapes. This material has been used for facial soft-tissue suspension, augmentation, and reconstruction and has demonstrated advantages over autologous grafts due to its optimal tissue incorporation, low infection risk, and biological inertness.

High-density porous polyethylene for facial bone augmentation.

Medpor is a porous polyethylene biomaterial used in plastic and reconstructive surgery in the craniofacial skeleton. Its porous nature allows for substantial vascular and soft-tissue ingrowth. Medpor is available in a variety of implants including block, sheet, and preformed shapes. In vitro and in vivo studies have demonstrated that Medpor has been successfully used in the reconstruction of the orbital floor and external ear, and in augmentation of the chin, mandibular, nasal, and malar regions.

Technical considerations in the use of polymethylmethacrylate in cranioplasty.

Polymethylmethacrylate (PMMA) is a self-curing acrylic resin that can be used in the repair of cranial defects. It is available in three forms: PMMA without mesh, PMMA reinforced with mesh, and PMMA preformed to fit a defect. In cranioplasty, the size and location of the defects provide the selection criteria for the use of PMMA. PMMA without mesh is ideal for small defects (5 cm2-15 cm2). PMMA reinforced with mesh is used for moderate sized defects (16 cm2-49 cm2). For very large defects (> or = 50 cm2), a CT scan guided mold is recommended because it provides the ideal contour and shape that simulates the normal skull.

Polydimethylsiloxane for augmentation of the chin, malar, and nasal bones.

Polydimethylsiloxane (PDMS) is used for augmentation of the chin, malar and nasal bones and is available through three different manufacturers. PDMS has been widely accepted by surgeons for bone augmentation because of its variability in hardness, its ability to be easily molded and shaped, and its biological inertness. Wound repair around PDMS implants is achieved through capsule formation. Fibrous capsule formation can be interrupted by infection, immune reaction, implant migration, or extrusion. Recent studies have shown no correlation between silicone implants and connective tissue disease.

Anorganic bovine bone and analogs of bone mineral as implants for craniofacial surgery: a literature review.

Hydroxyapatite compounds and a new anorganic bovine bone mineral are materials that offer an alternative to autologous bone grafting. Ceramic hydroxyapatite implants are limited in their usefulness due to difficulty in contouring the cortical form and the tendency for the granular form to exist outside the reconstruction site. These limitations have been overcome by the advent of a hydroxyapatite cement paste exhibiting good biocompatibility, contour manipulation, implant stability and osseoinduction. Preliminary studies indicate that a new resorbable anorganic bovine bone mineral with a chemical composition and structure similar to human bone promotes initial bony healing more readily than its synthetic hydroxyapatite counterpart, and therefore may serve as an excellent alternative for craniofacial reconstruction.
