High-performance liquid chromatography analysis of rubber allergens in protective gloves used in health care.

A high-performance liquid chromatography (HPLC) method developed for analysis of zinc dithiocarbamates was validated and used to perform a survey of disposable medical gloves used in southern Sweden. The gloves were extracted with acetone at room temperature for 10 min by shaking. The extracts were injected into a polyether ether ketone lined HPLC column, and peaks were analysed by a diode-array detector. The survey shows that of 19 gloves analysed, 10 contained zinc diethyldithiocarbamate (0.070-3.5 mg/g), 3 contained zinc pentamethylenedithiocarbamate (1.0-4.3 mg/g), 4 contained zinc dibutyldithiocarbamate (0.9-1.1 mg/g), and 2 contained 2-mercaptobenzothiazole (0.005-0.008 mg/g). None of them contained thiurams.

Leakage of virus through used vinyl and latex examination gloves.

A total of 480 examination gloves (240 vinyl and 240 latex) were stressed by using manipulations designed to mimic patient care. At the highest use level, 38 (63%) of 60 vinyl gloves leaked bacteriophage phi X174 compared with 4 (7%) of 60 latex gloves. At lower use levels, there was no statistically significant difference in leakage.

Bacillus species pseudobacteremia traced to contaminated gloves used in collection of blood from patients with acquired immunodeficiency syndrome.

Ten nonpathogenic Bacillus isolates were obtained from blood cultures collected over a 2-year period. Eight of these isolates were from patient with acquired immunodeficiency syndrome, and seven were recovered from blood cultures obtained in outpatient clinics. Five cases occurred during a 5-month period. These five cases were clinically evaluated, and the Bacillus isolates were characterized. The same Bacillus species was isolated from nonsterile gloves from the same lot worn by phlebotomists for blood collection in the outpatient clinics during this period, implicating the gloves as the cause of this pseudoepidemic. Awareness of the nonsterile nature of gloves used by laboratory personnel should be considered in the evaluation of Bacillus spp. in blood cultures.

Contact dermatitis from penetration of rubber gloves by acrylic monomer.

An orthopaedic surgeon developed dermatitis from acrylic materials. The acrylic monomer was found to penetrate surgical rubber gloves readily. Cases of "rubber glove dermatitis" with negative patch tests may have a similar explanation. Laboratory tests suggest that monomer does not damage rubber sufficiently to allow bacteria to penetrate gloves, but it remains possible that this would happen under theatre conditions.

Lung accumulations of eosinophil granulocytes after exposure to cornstarch glove powder.

Starch is a main component of wheat flour, which, besides being an occupational allergen can also induce irritative symptoms in the airways. A purified starch product (cornstarch glove powder) was used to investigate whether starch alone could induce airway inflammation. The aim of the study was to investigate a role for starch in wheat flour-induced airway inflammation. Ten healthy individuals were exposed to cornstarch glove powder in a whole-body exposure chamber. Bronchoscopy with bronchoalveolar lavage (BAL) was performed 2-3 weeks before and 1 day after exposure, and the BAL cells were counted differentially. In addition, the expression of activation, adhesion and subset markers on alveolar macrophages and BAL T-cells were investigated using flow cytometry. A three-fold increase in BAL cell concentrations was found, with a selective accumulation and activation of eosinophilic granulocytes, as well as an influx of nonactivated monocytes and polyclonal CD4+ T-cells into the airways. The results show that inhalation of cornstarch glove powder leads to the development of a subclinical inflammation in the airways, with an accumulation of eosinophilic granulocytes. The authors suggest that such exposure may be an interesting model for studying factors contributing to lung accumulations of eosinophil granulocytes in humans.

Technical note: an assessment of X-ray protective gloves.

An assessment of X-ray protective gloves is reported which demonstrates that a significant degree of protection from X-ray exposure can be offered by these gloves. The need for such protection, together with the method of assessment is discussed. It is recommended that X-ray protective gloves are considered when undertaking image intensifier work.

Infection control. 1: A practical guide to glove usage.

With increased demands from the general public for healthcare professionals to be accountable for their actions, many are becoming familiar with clinical governance and other initiatives to improve clinical practice. Good infection control is central to nursing practice. To achieve higher standards of clinical practice, especially when thinking about how to reduce the risk of cross-infection, it is necessary to not only do the right thing, but also do the thing right. Safe practice should be uppermost in the minds of healthcare professionals when caring for patients. This new series of articles attempts to look at the practical aspects of infection control, highlighting the requirements for risk assessment and applying the principles of infection control to a variety of patient care situations. This article investigates the use of protective clothing and gloves. It looks at the types of gloves available for use, the importance of choosing the correct glove for the task to be undertaken, and the modern day problems of allergies to latex.

Glove perforation during hip arthroplasty. A randomised prospective study of a new taperpoint needle.

Exposure to blood is a hazard for all surgeons. We assessed the incidence of glove perforation and needlestick injury from a new blunt taperpoint needle designed to penetrate tissues other than skin with the minimum of force. We performed a prospective, randomised trial comparing the incidence of perforations of surgical gloves with the new needle and a standard cutting needle during wound closure after hip arthroplasties. There was at least one glove perforation in 46 of 69 such procedures (67%). The use of the taperpoint needle produced a significant decrease in perforations (p = 0.049).

Gloved and ungloved: performance time for two dental procedures.

This study examines the time required to perform two routine dental procedures requiring fine hand manipulative skills--a pin placement procedure and an endodontic procedure. No significant time difference was noted in performing the procedures while wearing gloves or not wearing gloves. Twelve dentists who had routinely worn gloves for the past 6 months participated, each performing four procedures.

Fluorescein dye evaluation of glove integrity.

Several methods of defect detection in disposable latex and vinyl examination gloves were evaluated. Results of this research support other findings that glove integrity cannot be completely assured by the use of new gloves. The use of the fluorescein dye technique was superior, in terms of efficiency and accuracy in the clinical setting, when compared with other methods of defect detection, including the air inflation-water submersion technique.

Evaluating the effect of glove coating on the shear bond strength of porcelain laminate veneers.

Gloves have become a standard tool in dentistry due to infection control concerns. But the starch powder with which many of these gloves are coated may contaminate surfaces on contact, creating potential problems during adhesive procedures such as the placement of porcelain veneers. The authors studied the powder's effect on the strength of the shear bond of etched porcelain to etched human tooth enamel and compared it to the effect of a powder-free polymer glove coating. While the starch coating led to a statistically significant decrease in shear bond strength, the powder-free coating produced no significant decrease in strength.

Permeability of surgeons' gloves to methyl methacrylate.

The quick passage of methyl methacrylate at 21 degrees C and 35 degrees C through seven surgeon's glove materials in a diffusion chamber was quantified by gas-chromatographic analysis. Polystyrene-butadiene dissolved in methyl methacrylate, latex and polychlorobutadiene showed reversible expansion, during which material from the samples dissolved. In order to prevent these phenomena from interfering with the analyses, experiments were performed with 4.7 M methyl methacrylate in ethanol. Even then, the time in which methyl methacrylate permeated the membrane was too short for sufficient protection. When using these gloves, the orthopaedic surgeon who is fixing endoprostheses is no doubt occlusively exposed to methyl and other methacrylates, benzoyl peroxide, rubber additives, etc. Of glove materials which are not surgically used, vinyl was inferior to latex, whereas a very thin polyethylene copolymer did not change in methyl methacrylate, showed better resistance to diffusion, but was insufficiently elastic and easily perforated. A better protective material is urgently needed.

Evaluation of the extraction method for the cytotoxicity testing of latex gloves.

In this study, the cytotoxicity of medical latex gloves to cultured L-929 cells was determined using various extraction conditions. According to the extraction time and temperature, three types of extraction conditions were used: 1) 24 h at 37 degrees C; 2) 72 h at 37 degrees C; 3) 72 h at 50 degrees C. Also, four different extraction vehicles were used, namely, distilled water (DW), 9 g/l sodium chloride (saline) in DW, and culture media with or without serum. Under the above-mentioned conditions, the samples were extracted and then 2-fold serially diluted in the concentration range 3.13 - 50%. When extracted with either DW or saline for 24 h or 72 h at 37 degrees C, only 50% diluted samples showed distinct cytotoxicity to L-929 cells. Moreover, no cytotoxic potentials were observed when gloves were extracted with DW or saline at 50 degrees C for 72 h. Cytotoxicity was markedly greater when gloves were extracted with culture medium, irrespective of the presence of serum in the medium. These results suggest that optimal extraction conditions should be established for the cytotoxicity evaluations of biomaterials and medical devices.

[Identification of unknown substances in polyvinyl chloride gloves containing non-phthalate plasticizers].

The use of polyvinyl chloride gloves containing di(2-ethylhexyl) phthalate for food contact applications is restricted. In their place, polyvinyl chloride gloves containing non-phthalate plasticizers (PVC-NP) have been introduced. They contained unknown substances, so they were studied by GC/MS, HR-MS and NMR. The chemical structures of the unknown substances were confirmed to be diethylene glycol dibenzoate, triethylene glycol dibenzoate, dipropylene glycol dibenzoate, and alkylsulfonic acid phenyl ester, which are plasticizers. Including di-isononyl adipate, the contents of the plasticizers were 37.5-48.9% in the PVC-NP gloves, and their migration levels were 1,010-1,390 ppm into n-heptane. These are very high levels. These plasticizers are not widely used for food contact polyvinyl chloride throughout the world, and they have also not been registered as self-standards by Japanese manufacturers. Careful consideration will be necessary for the selection of a suitable plasticizer substitute.

Surgical glove hazards: a commentary.

Surgical contaminants of many kinds, including glove powder, cause granuloma formation. This is particularly well documented in the peritoneal cavity, but has been demonstrated in most anatomic sites. In addition, systemic manifestations result from the absorption of the latex protein antigens onto the starch powder on the surgical gloves, which is aerosolized when the gloves are donned or removed.

[Patients, surgeons and surgical gloves].

Consumption of surgical gloves in progressing constantly. All proposed products do not have the same qualities in terms of protection, comfort, and safety for the surgeon, the surgical team and the patient. Latex is the basic material used to manufacture surgical gloves even if it does raise the problem of side-effects and requires use of starch powder for lubrification. The surgeon should be aware of the different products and participate in choosing this indispensable tool. There is a general and advisable trend to using non-powdered gloves.
