Contact dermatitis due to surgical latex gloves--a personal experience.

Within an operating department, the health workers are subjected to various real or potential hazards, from laser rays to contamination by blood. The human immunodeficiency virus (HIV) is just one of the reasons why gloves are worn for all procedures where contamination is possible. Various types of rubber or vinyl gloves are used for many purposes. Sterile rubber (latex) gloves for surgical operations and examination, non sterile latex or vinyl gloves for personal protection and cleaning. Little attention is actually given to the wearers hands and an increasing number of operating theatre personal are becoming sensitive to latex gloves. In Finland in 1988, 7.4% of surgeons and 5.6% of operating theatre nurses had developed contact dermatitis. This is a serious problem. In extreme cases the nurse or doctor may have to leave their chosen profession. Contact dermatitis is not only restricted to the wearers hands. Case studies have shown that patients can also be allergic to their surgeons gloves. This is a worrying problem as we are the caring profession and are supposed to make the patients stay in hospital as trauma free as possible.

Latex allergy and gloving standards.

In response to universal precautions, latex gloves are used more frequently in health care settings, and more health care workers are reporting latex sensitivity or allergic reactions to natural rubber latex (NRL). As a result, there continues to be controversy about what gloves should be used in clinical practice and what are the appropriate clinical recommendations about gloving practices. This article reviews the current issues about gloving practices, addresses national standards related to gloving, and makes recommendations about future gloving practices.

The bionic glove: an electrical stimulator garment that provides controlled grasp and hand opening in quadriplegia.

OBJECTIVE: This report describes the operation of the Bionic Glove, a new functional electrical stimulation (FES) device designed to improve the function of the paralyzed hand after spinal cord injury (SCI) or stroke. DESIGN: Signals from a sensor in the glove detecting voluntary wrist movement are used to control FES of muscles either to produce hand-grasp or to open the hand. When the glove is donned, conductive areas on its inside surface automatically make contact with self-adhesive electrodes on the skin. SETTING AND PATIENTS: This report concerns nine people with SCI who have used the device in their daily lives for up to a year or more. Measurements were made at clinics in Edmonton, Miami, and Chicago as part of a multicenter clinical trial. OUTCOME MEASURES AND RESULTS: The mean peak force of tenodesis grasp in the nine subjects increased from 2.6N (passive) to 11.3N (glove active). Active force was significantly greater than passive grasp force even when muscles were fatigued after repetitive grasp-release cycles. Most manual tasks improved significantly with the use of the glove, as judged by the number of tasks completed in a minute or the subjects' qualitative ratings of task difficulty. CONCLUSION: The Bionic Glove can provide significant improvement of hand function in people with C6-C7 SCI.

A goniometric glove for clinical hand assessment. Construction, calibration and validation.

The construction of a goniometric glove is described. Each of the sensors in the glove was calibrated over a custom built metal hand using blocks of known angles as angular references. The digital data output from each sensor of the glove were converted into angular displacements at each joint. The glove was validated for consistency of measurement and accuracy over a custom built metal jig and in the human hand. The accuracy of the glove was found to be within the limits of traditional goniometry. It is proposed that goniometric gloves could be useful in the assessment of hand function.

Finger doses during interventional radiology: the value of flexible protective gloves.

Finger doses of radiologists and assistants during 19 interventional radiological procedures were measured with thermoluminescent dosimeters (TLDs), and two types of flexible protective gloves were compared with each other. There were considerable differences in doses between different sites of TLDs on fingers. The exact site of TLDs on hands/fingers should thus be reported in papers. Both gloves were also irradiated through an Alderson phantom and the attenuation values were measured. The gloves with slightly greater attenuation proved to be significantly less comfortable to use. Wearing flexible protective gloves did not lengthen screening times as compared to a previous study in the same department. Various aspects of using such gloves are discussed. The attenuation values of gloves reported by the manufacturers may not apply under all clinical circumstances.

Permeability of Organic Solvents Through Two-Layer Safety Gloves Determined by a Gravimetric Method.

Organic solvents are harmful to humans and many of them are recognized as carcinogens. Therefore it is necessary to protect hands from contact with them. Most methods for testing solvent resistance of gloves use Gas Chromatography. However, these methods are expensive and so complex that they present application problems for most glove producers and users. A simple gravimetric method to test solvent resistance of gloves was developed. It was tested by measuring permeability of organic solvents such as white spirit, acetone, isopropyl alcohol, benzene, p-xylene, trichloroethylene, through gloves made of natural rubber, polivinyl chloride, neoprene, perbunan, polivinyl alcohol, and two-layer gloves made of natural rubber and neoprene. This method proved to be a simple, economical, and reliable way to examine glove permeability.

The permeation by liquefied coal of gloves used in coal liquefaction pilot plants.

The protective capabilities of PVC, natural rubber and milled nitrile rubber gloves currently used in coal liquefaction pilot plants were assessed and the effectiveness of a laundering method was evaluated. The breakthrough times and cumulative permeation for exposure to toluene and to liquefied coal were determined by measurement of radiolabeled phenol tracer in the aqueous receiving medium. Breakthrough times, normalized by division by the square of the material thickness, agreed with the findings of other studies. On exposure to liquefied coal, the nitrile laboratory glove resisted breakthrough the longest (between 12 and 24 hours), although it was the thinnest material tested. Breakthrough times for the other gloves ranged from 2.75 to 6.5 hours with the times for the natural rubber glove materials intermediate to the two PVC glove materials tested. However, when normalized for thickness, both PVC materials were more resistant to breakthrough than rubber. It was found that the laundering method did not completely decontaminate samples of PVC glove material pre-exposed to liquefied coal for 24 hours under laboratory conditions.

Pesticide glove permeation analysis: comparison of the ASTM F739 test method with an automated flow-through reverse-phase liquid chromatography procedure.

The results of two methods of analysis for measuring glove permeability to pesticides are reported. The standard ASTM F739-85 testing procedure was used to determine breakthrough times and permeation rates for four protective glove materials for two commercially available pesticide formulations. The same glove materials and pesticides then were tested using an in-house developed automated in-vitro diffusion analysis (AIDA) procedure. The ASTM and AIDA procedures both demonstrated no detectable breakthrough of Sevin 50W or 2,4-D Amine 96% for nitrile butyl rubber and polyvinyl chloride gloves. Although no breakthrough of Sevin 50W or 2,4-D Amine 96 was detected for natural rubber or neoprene gloves following the ASTM procedure, permeation was observed in 2 of 3 replicate tests for both rubber and neoprene gloves when using the AIDA method. The observed discrepancy may have been caused by a longer sampling duration for the AIDA method (16 hr) than the ASTM procedure (8 hr). Advantages of the AIDA procedure are discussed.

Self-reported allergy to latex gloves among health care workers in Jordan.

The objective of this study is to determine the prevalence of natural rubber latex allergy and its associated factors among health care workers in Jordan based on a self-administered questionnaire. In this cross-sectional study, the data were obtained through a self-reported hand-delivered questionnaire that was distributed to 500 health care workers who use natural rubber latex gloves. A total of 420 (84%) health care workers responded by filling the questionnaire. Of the total number of 420 health care workers who filled the questionnaire, 57 (13.6%) reported allergy to latex gloves. The prevalence of allergy to latex gloves was significantly higher for those who had allergy to some foodstuffs (especially avocado, kiwifruits and chestnuts) or with history of eczema and hay fever. However, allergy to latex gloves was independent of gender, age, job, family history, type of gloves, hours of use/day and number of years of use. It is concluded that a high rate of allergy to latex gloves was reported among health care workers in Jordan.

Results of wearing test with two different latex gloves with and without the use of skin-protection cream.

A total of 109 subjects reporting symptoms indicating type I hypersensitivity reactions to natural rubber latex (NRL) gloves was included in this study, and 66 of them had latex-specific IgE antibodies. They underwent provocation tests by wearing two types of NRL gloves with high (n=103) and low (n=75) allergen contents. The first glove type caused positive skin reactions in 30% of IgE-positive and in 3% of IgE-negative subjects. After application of a commercially available skin protection (barrier) cream, the frequencies of positive skin responses in wearing tests increased to 41% and 7%, respectively. The gloves with low allergen content did not cause hypersensitivity without skin-protection cream but induced responses in 5% of IgE-positive subjects when this cream was applied. Corresponding findings were obtained in intraindividual comparisons of test results, which were possible in 69 cases. Of all wearing-test responders, 92% had latex-specific IgE antibodies. Our results demonstrate that high allergen contents in latex gloves frequently elicit skin responses in NRL-sensitized subjects, and that skin-protection creams may favor the uptake of allergens from gloves, thus increasing allergic reactions. The stipulation of a legally binding threshold limit value (TLV) for allergens in NRL products is urgently needed. This TLV should not be set above 2 microg allergen/g rubber.

Increase of heat loss by wearing gloves and boots in wet-suited subjects working in cold water.

The effect of wearing protective gloves and boots on thermal exchanges of wet-suited subjects in cold water was evaluated. Four male subjects, clad in 5 mm-thick neoprene wet suits and either with or without neoprene gloves (5 mm-thick) and boots (5 mm-thick) were immersed up to the neck in water at 13 degrees C while resting for 3 h or exercising for 2 h. Rectal temperature, oxygen consumption and local (chest, back, upper arm, thigh, forearm, calf, hand and foot) skin temperatures, skin heat fluxes and thermal insulations were determined during immersion. The rectal temperature was not different between conditions but the skin temperature was significantly higher with gloves and boots, especially at the distal extremities (forearm, calf, hand and foot). Consequently, the core-to-skin temperature gradient was reduced by wearing gloves and boots, but the skin heat loss was markedly increased. Calculated overall body insulation was significantly lowered by wearing gloves and boots. These results indicate that in wet-suited subjects resting or exercising in cold (13 degrees C) water, gloves and boots increase the overall rate of body heat loss. Attenuation of cold-induced vasoconstriction is proposed as the mechanism.

[Shielding ability of lead loaded radiation resistant gloves].

The shielding ability of radiation resistant gloves was examined. The gloves are made of lead loaded (as PbO2) polyvinyl chloride resin and are about 0.4 mm in thickness (70 mg/cm2). Eleven test pieces were sampled from each of three gloves (total 33) and the transmission rates for radiations (X-ray or gamma-ray) through the test pieces were measured with radiation sources, 99mTc, 57Co, 133Ba, 133Xe and 241Am. The differences of the transmission rates for radiations by the positions of the gloves were smaller than 15%, and the differences by three gloves were smaller than 5% in the case of 60 keV and 141 keV radiations. The average transmission rates for radiations in the 33 test pieces were about 40% for 30 keV radiation, about 90% for 80 keV and 140 keV radiations. The shielding characteristic of the gloves is equivalent to about 0.026 mm thick lead plate.

The effects of weight levels and gloves on the ability to discriminate weight difference.

In this study, six different types of gloves commonly used in industry (surgical, cotton, nylon, leather, rubber, and whizard knife hand gloves) were evaluated at four different weight levels (8.2, 3, 1.5 and 0.25 kg). Six males and six females voluntarily took part in this study. The dependent variable was the difference limen (or difference threshold) (abbreviated as DL(%)) of the discriminating weight difference (DWD). A nested-factorial design with the subject nested under gender was employed. The results indicate that the weight level had a negatively significant effect on the DL(%). The mean difference thresholds were 3.49, 5.39, 6.08, and 9.45 for the weight levels at 8.2, 3, 1.5, and 0.25 kg, respectively. The individual difference becomes obvious when the weight level is relatively light (0.25 kg). However, the effects of gender, glove, gender x weight, and weight x glove were found to be insignificant, and there was no significant correlation between the DL(%) and glove characteristics (thickness and weight). Subsequently, four additional weight levels (0.01, 0.5, 1 and 15 kg) were considered, and a psychophysical equation was derived: DL(%) = 34.33 x W(0.238) (R2 = 0.98), where W represents the weight level. These results support the power function. A minimum weight difference with 90% confidence of correct detection was suggested.

[Colorimetric determination of the total protein eluted from latex gloves].

Recently type I hypersensitivity reactions caused by latex gloves have been reported. The protein from latex gloves is considered to be responsible for this allergy. We investigated the extraction conditions and the assay methods for the purpose of the colorimetric determination of the total protein eluted from latex gloves. In a series of experiments, it was demonstrated that elution of the protein was very rapid, and changes of the extraction buffer volume (1.7-20 ml/g) had no appreciable effect on the extraction efficiency. Moreover, comparison experiments of the four assay methods revealed that Ninhydrin method was significantly interfered by low molecular weight substances other than protein and that Bradford method suffered from the poor reproducibility. On the other hand, Lowry method and Bicinchoninic acid (BCA) method gave relatively good results. Based on these experimental results, we established a typical procedure for quantitative analysis of the total protein as follows. Two grams of latex gloves specimens are extracted with 10 ml portions of phosphate buffered saline pH 7.4 (PBS) at room temperature for two hours, and then the resulting solution is assayed by BCA method. According to this procedure, commercially available ten kinds of latex gloves were analyzed. We found that the amount of the extractable protein was considerably varied with the products.

Glove-related rhinopathy among hospital personnel.

Hypersensitivity to natural rubber latex (NRL) in health care personnel exposed to powdered latex gloves appears as conjunctivitis, rhinitis, nasal congestion, cough, dyspnea, or bronchial asthma in approximately 30% of all cases with latex allergy while most of the patients have contact urticaria. The purpose of the present study was to determine the prevalence of latex-induced allergic rhinitis in health care workers using NRL gloves on a daily basis. Clinical examination accompanied by skin prick test (SPT) with latex glove extracts and common aeroallergens, measurements of specific IgE to NRL, and lung function tests were performed in 25 symptomatic workers and 11 latex-exposed asymptomatic controls. Sensitization to NRL was detected using SPT in one (4%) of 25 symptomatic workers but not in any of the asymptomatic controls. Positive SPT to aeroallergens was demonstrated in 8/25 symptomatic workers and 6/11 controls. Measurements of forced vital capacity, forced expiratory volume in I sec, and bronchial methacholine challenge did not show any significant differences between the study groups. In conclusion, NRL-aeroallergen-induced occupational rhinitis may occur among physicians and nurses who have a frequent use of latex gloves on a daily basis at hospital work. However, a relatively low prevalence of NRL-induced occupational rhinitis is associated with profuse consumption of no-powder sterile gloves.

Change in permeation parameters and the decontamination efficacy of three chemical protective gloves after repeated exposures to solvents and thermal decontaminations.

BACKGROUND: Chemical protective clothing (CPC) and gloves, which provide adequate protection, are usually too expensive to be considered disposable. Repeated use of CPC without effective decontamination may result in secondary exposure and injury. However, decontamination may change the physical and/or chemical properties of the barrier material, causing variations in breakthrough time (BT) and steady-state permeation rate (SSPR). METHODS: Glove materials including neoprene, Guardian butyl rubber, and nitrile synthetic rubber were selected for this study. Toluene and acetone were chosen as the challenge chemicals. Permeation was measured in a closed loop system using a 2.5 cm permeation cell and a MIRAN infrared analyzer (Foxboro, MA). Following the permeation test, the samples were thermally decontaminated. After each exposure/decontamination cycle, BT and SSPR were measured. A total of 260 permeation tests were conducted. Permeation test results were collected on each material/chemical combination for up to 10 exposure/decontamination cycles. RESULTS: On average, changes in BT and SSPR in comparison with respect to new swatches were 11.5% and 13.7% after seven exposure/decontamination cycles. The percentages increased to 26.6% and 15.9% after 10 exposure/decontamination cycles, respectively. For at least seven cycles, the BT mean for four out of five material/chemical combinations tested (neoprene/acetone, neoprene/toluene, nitrile/acetone, and nitrile/toluene) was not significantly different from the original value of the BT for each corresponding swatch. Similarly, the SSPR mean for each of the five material/chemical combinations after at least five cycles was not significantly different from those for new swatches. The BT mean for the butyl/toluene combination, however, was significantly different from the new swatches even after the first exposure/decontamination. The SSPR mean was significantly different after five cycles compared to the new swatches. CONCLUSIONS: Except for the butyl/toluene combination, thermal decontamination was an effective method in removing the solvents from the matrix of selected glove materials. Multiple reuses of some chemical protective gloves could be safe if effective decontamination methods are used and the glove materials do not have significant degradation.

The pathological effects of glove and condom dusting powders.

Dusting powders are used on latex gloves and condoms. They help to release these products from their moulds during manufacture and facilitate processing and donning. Dusting powders are also used on contraceptive diaphragms, sanitary napkins and in toiletries. There are numerous dusting powders in current use around the world. At present a consensus exists about the best dusting powder to use on surgical gloves, based on data about the safety of these agents in humans, as well as their manufacturing qualities. No such consensus exists for the use of dusting powders in other situations. However, there is uncertainty about whether dusting powders used in situations other than on surgical gloves are responsible for harmful effects. This study uses intraperitoneal injections in rats to examine the pathological effects of dusting powders that are in current use on surgical gloves and condoms. We suggest that dusting powders may be a source of morbidity when used in situations other than on surgical gloves and confirm the findings of previous investigators that the dusting powders we tested differ in their ability to produce pathological effects.

The efficiency of protective gloves used in the handling of cytotoxic drugs.

A range of clinical and industrial gloves have been evaluated to determine their ability to exclude penetration by cytotoxic drugs. Radiolabelled cyclophosphamide, methotrexate, daunomycin, cytosine arabinoside, and vincristine sulphate were studied in an equilibrium dialysis system in which the glove material was used as the dialysis membrane. The thicker gloves were the most effective, but very little drug crossed any of the gloves tested under laboratory conditions. Further studies to evaluate gloves in conditions of clinical use are now needed.
