Ponencia del calzado - Las neuropatías del calzado y su posible relación con inhibidores de colinesterasas
The incidence of toxic neuropathy in the shoe industry in Italy, Japan and Spain is compared. The similarity between this neuropathy and poisoning with triorthocresyl phosphate (TOCP) and other neurotoxic agents is discussed, followed by a review of work on the detection of cholinesterase inhibitors in industry and of cholinesterase and its derivatives acetylcholinesterase and butyrylcholinesterase (pseudocholinesterase) - catalytic reactions, location and functions (synapse physiology). The effects of cholinesterase inhibition by toxic agents such as TOCP are discussed (acetylcholinesterase inhibition, late neurotoxic effects and inhibition of pseudocholinesterase).

Neurotoxic metabolites of "commercial hexane" in the urine of shoe factory workers
Urine samples collected at the end of the work shift from 41 shoe factory workers were analysed for metabolites of 10 solvents of which commercial hexane was the main component. The concentration of these solvents was determined in breathing zone samples. 2,5-hexanedione was the principal hexane metabolite found in the workers's urine and is believed responsible for the development of neuropathy in this group of workers.

H-reflex behavior in glue (n-hexane) neuropathy
The H-reflex response, and in particular the excitability cycle of spinal motor-neurones, were studied in a group of 12 females aged 19-41 years suffering from marked peripheral neuropathy. Motor and sensitive nerve conduction, electromyography, and clinical features were considered. An increased excitability of α-motor neurones was evident indicating spinal involvement in these patients.

Experimental neurotoxicity and urinary metabolites of the C5-C7 aliphatic hydrocarbons used as glue solvents in shoe manufacture
Rats were exposed to hexane, cyclohexane, pentane, heptane, and 2- and 3-methylpentane at 500-5,000ppm for 9-10h/day, 5-6 days/week for 7-30 weeks. None of the animals developed signs of neuropathy. Animals treated with hexane at 5,000ppm for 14 weeks or 2,500ppm for 30 weeks developed the typical giant axonal degeneration. No such alterations were found in rats subjected to the other solvents. Urinary metabolites of the various solvents were determined: 2-hexanol was the metabolite of hexane, while 2,5-hexanedione was present in smaller amounts. 2,5-hexanedione appears to reach an effective level at its site of action, during intermittent treatment with hexane, with difficulty; this explains the high concentrations necessary to cause polyneuropathy.

Nasal cancer in England and Wales: An occupational survey
Report of an epidemiological survey of nasal cancers registered in England and Wales in 1963-1967 to determine the occupational history of the patients and their smoking and snuffing habits. Data were collected by postal survey of the patient or close relative (1935 cases); in 104 cases, interviews were carried out to obtain more precise information on the nature of the job or the type of dust the worker might have been exposed to. The survey confirmed the high incidence of nasal cancer in cabinet makers and wood machinists, no significant increase in incidence in carpenters and joiners, increases in boot and shoe operatives and repairers, and in nickel smelters. The significant excess of cases found among coalminers, gas, coke and chemical industry furnacemen, and foundry furnacemen and labourers may be associated with coal and coke dust exposure. No excess incidence was found among textile workers. Study of nasal tumour histology gave no definite indication of any association between histological type and occupation, except in the well-know relation between adenocarcinoma and furniture and footwear industry work.

Urinary excretion of the metabolites of n-hexane and its isomers during occupational exposure.
Environmental levels of the components of commercial hexane were measured in 5 shoe factories: they were 32-500mg/m3 for n-hexane, 11-250mg/m3 for 2-methylpentane, and 10-204mg/m3 for 3-methylpentane. Urinary metabolites found in 41 workers at the end of the work shift were 2-hexanol, 2,5-hexanedione, 2,5-dimethylfuran, and γ-valerolactone (for n-hexane), and 2-methyl-2-pentanol and 3-methyl-2-pentanol. n-Hexane exposure was correlated more positively with 2-hexanol and 2,5-hexanedione than with its other 2 metabolites. There was a good correlation between n-hexane exposure and total metabolites. The respective metabolites were highly correlated with 2- and 3-methylpentane exposure. Urinary excretion of metabolites may be used for monitoring exposure to n-hexane and its isomers.

Are carcinogens a chronic health hazard in the tannery workplace?
A review of the epidemiological and case-history studies on which are based the accusations that the leather and leather products industry in the USA is a significant contributor to industrial carcinogenesis. 5 categories of chemical substances are defined (nitroso amines; dyes, especially benzidine-based direct dyes; chromium chemicals, especially insoluble chromate pigments; aromatic organic solvents; and tannin), their carcinogenic potential reviewed and their use in various sectors of the leather industry analysed. Recommendations are given on control of exposure to these substances for different leather industry jobs. The industry's reputation of being a high-risk industry for occupational cancer has not been validated.

Glue polyneuropathy in the Campania region - Clinical and epidemiological aspects - Experimental study
La polineuropatia da collanti nella regione Campania: aspetti clinico-epidemiologici - Contributo sperimentale [en italiano]
42 workers with glue polyneuropathy at various stages were studied as well as 60 workers still active in shoe manufacture. Workers' subjective assessments were a useful criterion of the presence of latent polyneuropathy. EMG studies confirmed nervous conduction disturbances in a high percentage of subjects still in activity. Determination of serum cholinesterase was the most valuable laboratory test. The presence of triorthocresyl phosphate in synthetic leather is considered a factor in the development of the clinical symptoms.

Pollution by solvents and workers' positions in shoe upper factories
Inquinamento da solventi e mansioni lavorative nei calzaturifici e tomaifici [en italiano]
4 shoe factories and 3 shoe upper factories were studied. n-Hexane, 2- and 3-methylpentane, cyclohexane, and methylcyclopentane were found in the atmosphere of all factories. Acetone and methylethyl ketone were present in the shoe, but not the shoe upper, factories. Levels of the solvent mixture were higher than the calculated TLV in the shoe factories lacking ventilation facilities and in all the shoe upper factories. Peripheral neuropathy was found in 3 workers exposed to n-hexane concentrations above 360mg/m3.

Lung uptake and metabolism of cyclohexane in shoe factory workers.
Cyclohexane (CH) in environmental air, alveolar air and blood, and cyclohexanol in urine were determined in 22 workers. All parameters correlated well with one another. Mean alveolar CH was 78% of environmental CH. Blood CH was 53-78% of alveolar CH. Urinary cyclohexanol corresponded to 0.1-0.2% of absorbed CH. Biological monitoring of CH in the alveolar air and urine is a reliable means of determining occupational exposure.

Cancer risks associated with employment in the leather and leather products industry.
Case-control studies are reported in workers at plants manufacturing leather products, and shoemakers and shoe repairers. In men, the relative risk increased with duration of employment and was independent of smoking habits. Male leatherworkers showed significant increased risks for mouth, pharyngeal and laryngeal cancers. There was an elevated risk of malignant lymphomas in men and women.

Vestibular changes in shoe manufacturing workers
Alterazioni vestibolari in operai calzaturieri [en italiano]
Studies in 78 workers exposed to n-hexane, 2-methylpentane, 3-methylpentane, methylcyclopentane present in the glues and 86 controls showed a statistically significant higher prevalence of vestibular function changes in the exposed workers. The changes were typical of the toxic nucleo-reticular syndrome, involving the nerve structure of the medulla oblongata. Symptoms complained were emotional disorders (48%), dyspeptic disturbances (29%), subjective vertigo (20%), headache, asthenia, mucosal irritation. Exposure levels were not high, and there was no dose-effect relation.

Allergic properties of p-tert-butylphenol-formaldehyde resins
Zur Allergennatur der para-tert. Butylphenolformaldehydharze [en alemán]
On account of the widespread use of polychloroprene glues containing a p-tert-butylphenol-formaldehyde resin in the shoe and leather industry, and the increased incidence of allergic contact eczema it produces, the allergic properties of these resins were studied in depth. The allergological investigations, the methods used and the reactions obtained with the substances tested are described. P-tert-butylphenol-formaldehyde does not appear to be the most important hapten involved. The eczematogenic substances identified are described.

Value of haematochemical indicators in the prevention of glue polyneuropathy
Valore di alcuni indici ematochimici nella prevenzione medica della polineuropatia da collanti [en italiano]
Serum glutamic oxaloacetic and pyruvic transaminase, lactate dehydrogenase, alkaline phosphatase, creatine phosphokinase, aldolase, γ-glutamyl transpeptidase, and serum and erythrocyte cholinesterase were measured in 60 shoe workers and 20 rabbits exposed to the solvents of the glues most commonly used (chief constituent n-hexane). There were no subjective or objective signs of polyneuropathy in the workers, and laboratory tests showed no significant changes in either the animals or the humans. Electroneurophysiological examination showed preclinical signs in 9 of 11 workers. This appears to be the only early test of polyneuropathy. A fall in serum cholinesterase may also be of value as a warning signal.

Glue neuropathy: Epidemiological study and preliminary results of experimental poisoning
Neuropatia da collanti: Inquadramento epidemiologico e risultati preliminari di intossicazioni sperimentali [en italiano]
After a review of the literature (incidence, aetiology), results of studies in chickens with glue distillates used in the shoe industry, hydrocarbon mixtures and tri-o-cresyl phosphate (TOCP) are reported. The chickens developed paralysis, with diffuse degeneration of the myelin sheath and of central and peripheral neurons. Cyclohexane and TOCP are regarded as the probable cause of toxic polyneuritis in shoe workers.

Polyneuropathy in the shoe industry: an experimental, aetiological and clinical contribution
Polineuropatia nell'industria calzaturiera: Contributo sperimentale, etiologico e clinico [en italiano]
An investigation in 20 shoe manufacturing plants, using new methods of factory sampling and laboratory testing, is reported. The proportion of tri-o-cresyl phosphate (TOCP) was high in many imitation leathers used. Solvent pollution (mainly n-hexane) was generally high. Electromyographic examination of 120 glue-exposed workers showed 18 cases of subclinical polyneuritis. The possibility that other agents in addition to TOCP or n-hexane are involved in the toxic effects is discussed. Elimination of TOCP as a component of unprocessed materials, and radical lowering of the threshold limit value of n-hexane, are recommended.

Severe epidemic of skin disease due to Ursol in fur industry workers
Hromadný výskyt kožních onemocnění z ursolu u pracujících v kožešnickém průmyslu [en checo]
The epidemic occurred in 1970 among the personnel of a fur garment factory in southern Bohemia. It was manifested by burning of the eyes, oedema of the eyelids, burning of the throat, coryza and cough, and spasmodic breathing difficulties in isolated cases. The commonest manifestation was occupational dermatitis, in 49 subjects (20 cases of contact eczema and 29 of toxic irritative dermatitis). The epidemic was chiefly due to technical changes (use of a new protective grease), as a result of which residues of the dye based on Ursol D (p-phenylenediamine) were not completely removed by washing, giving rise to a risk of contamination by traces of free diamines during garment manufacture. Prevention measures (stricter control of pollution, ventilation, possibly substitution of Ursol-based dyes) eliminated the hazard.

Shoe workers' polyneuropathy - Aetiology and epidemiology
La polineuropatia "dei calzaturieri" - Etiologia e epidemiologia [en italiano]
The clinical picture of this condition if briefly reviewed, with attention to the distinction between mild and severe forms. Epidemiological data from the literature are presented showing the great increase since 1957 in incidence of polyneuropathy caused by exposure to glue; 490 cases were reported in 1957-1973. Data on the authors' studies in 122 affected workers are reported. The hypothesis that tri-o-cresyl phosphate (TOCP) is responsible for the condition is discussed in some detail. Conclusions: the chief causative factors are inhalation of paraffin hydrocarbons with a low boiling point used after the prohibition of benzene (n-hexane, pentane, 2-methylpentane, etc.) and possibly others, including TOCP; unsatisfactory hygiene conditions leading to excessive exposure.

Formaldehyde-p-tert-butylphenol resins and p-tert-butylphenol in occupational medicine
Les résines formaldéhyde-paratertiaire butylphénol et le paratertiaire butylphénol en médecine du travail. [en francés]
Report of a study of the role of formaldehyde-p-tert-butylphenol resins and their starting materials in allergic disorders in the footwear industry and in shoe repair workers. Preventive measures include: modification of concentration, gluing to be carried out in isolated premises, precautions in handling, use of impermeable aprons, personal hygiene, worker information. A group allergy may exist between p-tert-butylphenol and the resin itself, although each product individually is capable of producing sensitisation; p-tert-butylphenol, in the manufacturing stage and in the chemical industry, can cause achromia which can be reproduced in animal experiments.

Shoe-makers' polyneuropathy in Italy: the aetiological problem.
122 cases of shoemaker's polyneuropathy occurring in 1971-1974 are reviewed. Samples of the glues and solvents used were analysed. The disease is more common in women (68%) than in men, and generally begins during winter or early spring. It occurs almost exclusively among workers in small shoe factories with low standards of hygiene. The primary causative agents are probably paraffin hydrocarbons with a low boiling point (pentane, 2-methylpentane, 3-methylpentane, n-hexane, etc.) rather than the triorthocresyl phosphate most often held responsible.

Risk of electrostatic buildup during glue production
Riziko elektrostatických nábojů při výrobě lepidel [en checo]
This study is concerned with glues for the shoemaking industry, prepared from natural and synthetic rubbers or polyurethanes dissolved in commercial grade petrol or various combinations of toluene, acetone and ethyl acetate. The risk of formation of electrostatic charges is present mainly at the mixing stage. After stating the problem, the authors report the preventive measures taken in the undertaking concerned: earthing of all conductive parts of machinery; elimination of polyethylene in the packing material for the glue granulate; injection of solvents tangentially to the mixer wall by a non-sparking metal nozzle; improvement of conductibility of granulates by means of conductive additives which do not affect the properties of the end-product; maintenance of a moderate flow rate of the solvents in relation to the pipe diameter.

Hematological and neuro-muscular response of workers exposed to low concentration of toluene vapor.
Report on studies in 38 female shoe industry workers exposed to 60-100ppm toluene, and a control group. Subjective symptoms (weakness, dysmenorrhoea, itching, dermatitis of hands) were significantly more frequent in the exposed group. The other chief differences found were in the rate of Mommsen's toxic granules in the peripheral neutrophils, urinary hippuric acid levels, and results of neuromuscular function tests. It is suggested that the TLV for toluene in Japan, 100ppm, be reconsidered.

Safe work with rotary tanning drums
Bezpečnost pracujících při práci s koželužskými sudy [en checo]
The Council of Europe has adopted the following recommendations concerning rotary tanning drums (CIS 442-1970, Jz Xje (054)): the rotating parts of these machines should be fenced to prevent access, by enclosures, railings or other means; automatically-operated rotary drums should be fitted with a guard or fence electrically interlocked with the drum power drive, as well as a mechanical device for blocking or securing the drum (brake, prop, etc.). Pits under the drums should be surrounded by a toe-board at least 5cm in height. Examples of the application of these recommendations in the Czechoslovak tanning industry.

Chromium carcinogenesis, formation of epoxyaldehydes and tanning.
This letter to the editor offers a possible explanation of the carcinogenic action of calcium chromate in arachis oil and a possible connection with the tumours among tanners. The triglycerides in the oil are hydrolysed by lipases from lysosomes in damaged cells. The glycerol and polyunsaturated fatty acids are oxidised by the chromate to carcinogenic aldehydes and epoxy aldehydes, e.g. trimethoxycinnamaldehyde (from acrolein) and glycidal. There is an analogy between carcinogenesis and the process of tanning; chrome tanning depends upon reactions of epoxy aldehydes with amino acids. Similar mechanisms may also operate for other oxidising agents and explain the anticarcinogenic role of antioxidants.

Toxic polyneuritis in footwear industry workers - A longitudinal electromyographic study
Polineuropatia tossica in operai dell'industria calzaturiera - Studio elettromiografico longitudinale [en italiano]
Results of repeated electromyographic tests in 15 young workers in the footwear industry who were exposed for several years to solvent vapours from leather adhesives. Sensorimotor polyneuritis of the upper and lower limbs was diagnosed in 12 of them (i.e. 80%), and in the 3 others the lower limbs only were affected. The authors were unable to establish a correlation between the clinical symptoms and the electromyograms. They noted in most cases a diminution of the polyneuropathy 18 months after the first symptoms were observed.
