Autonomous sensory polyneuropathy of upper extremities is one of the most common occupational diseases of peripheral nervous system. Findings of the study of working conditions in two major worker jobs in which occupational polyneuropathies of upper extremities are prevalent, namely: house-painters and plasterers, as well as mining job workers (underground miners, shaft miners, breakage face miners) are reported. Hygienic investigations envisaged detailed studies of working conditions in workers with diagnosed occupational peripheral nervous system disease. The intensity and hardness of working process, illumination level, spectral noise characteristics, noise, vibration, temperature, humidity, and air velocity levels, as well as adverse chemical concentrations in workplace air were assessed. House-painters as well as miners were found to work with pronounced physical overloads, working conditions being classified as 3.2-3.3 (2-3 degree harmful) according to indices of working process hardness. In spite of new technologies being introduced into the working process, manual labor part in these jobs still remains to be the great. Comparison of findings revealed certain differences in some characteristics of working process hardness. Working process hardness shown by dynamic and static physical load on upper extremities was found to be the most significant harmful occupational factor resulting in polyneuropathy in house-painters and plasterers. Development of polyneuropathy in miners was caused by a combination of adverse occupational factors: working process hardness, local vibration, cold microclimate. Our findings indicated the importance of the study of health state in painters and miners. Working conditions must be taken into account in the process of development of preventive and remedial measures for occupational polyneuropathy treatment.

Sensory Polyneuropathy

Introduction. Autonomous sensory polyneuropathy of upper extremities is one of the most common occupational diseases of the peripheral nervous system. Materia and methods. Findings of the health state study in two major worker jobs in which occupational polyneuropathies of upper extremities are prevalent, namely: house-painters and plasterers, as well as mining job workers (underground miners, shaft miners, breakage face miners), are reported. The main harmful factor in both professional groups is the heaviness of the working process. Results. Physical overloads are a reason of the occupational pathology’s complex of “working hand”. At the same time, no systemic autoimmune or endocrine diseases with similar polyneuropathy were detected. Other harmful factors in the working process such as occupational dust, intensive noise can cause another occupational pathology (in respiratory or hearing organs). Discussion. In spite of obviously different working conditions, we detected the same professional diseases in both professional groups - “the working hand pathological complex”. Our findings indicated the importance of the regular periodic check-ups. Doctors should search actively the early signs of coexisting with the occupational polyneuropathy illnesses. The results of health state’s research should be taken into account in the patient’s treatment planning.

Introduction. The article presents the results of a study of working conditions and the health status of patients with occupational polyneuropathy (PNP) of the upper limbs. Such a clinical and hygienic assessment of people with occupational PNP contributes to the optimal examination and treatment of patients with the preliminary diagnosis who are referred to occupational pathology centers.Material and methods. The study included 236 patients of two main occupations (painters-plasterers and miners): 113 women and 123 men. Results. The average age of patients at the time of the examination was: for painters-plasterers (women) - 55.5 ± 5.7 years, for miners (men) - 53.9 ± 6.3 years. Work experience of patients with physical overload at the time of diagnosis of occupational PNP accounted for plasterers - 25.1 ± 8.0 years, for miners - 20.4 ± 6.7 years. Working conditions of plasterers and miners were revealed to contribute to the development of occupational diseases of the peripheral nervous system and musculoskeletal system from the effects of physical overload and functional overstrain of the muscles of the upper extremities. Most often occupational PNP of the upper limbs is accompanied by the parallel development of professional chronic shoulder-scapular periarthrosis, epicondylosis, myofibrosis of the forearms, and shoulder girdle (a complex of occupational pathology of the «working hand»); radiculopathy of the cervical and lumbosacral levels.Conclusions. The main common harmful factor in the examined patients is the severity of the labor process. In less than one-fourth of the examined patients (15,7%) occupational PNP of the upper limbs was the only occupational disease. In other cases, its development was accompanied by the appearance of other occupational diseases of the peripheral nervous system and the musculoskeletal system. Patients referred to the examination in occupational pathology centers with a diagnosis of “PNP of the upper extremities” need a comprehensive examination to verify a possible complex of occupational pathology.

Introduction. Among the various methods of diagnosis and prediction of peripheral nerve injuries of the upper extremities, stimulation electroneuromyography plays a significant role. Occupational polyneuropathy of the upper extremities in coal miners is a common pathology. This pathology can lead to a disability of the active population, which makes the problem to be socially significant. Stimulation electroneuromyography is a method of choice in the diagnosis and prediction of peripheral nervous system diseases. Material and methods. 40 miners aged from 42 to 65 years, employed in hazardous working conditions (vibration, physical overload, gas pollution, adverse climatic conditions) were surveyed. As a control group, 12 healthy subjects of the same age without the signs of peripheral nervous system disease were examined. A clinical and electrophysiological study was conducted, including a clinical investigation, a quantitative assessment of subjective complaints on the Total Symptom Score (TSS) scale and stimulation electroneuromyography. Results. Occupational polyneuropathy developed in all surveyed workers employed in adverse working conditions; it was characterized mainly by myelinopathies of motor and sensory nerve fibers. In the clinical picture there were dominated sensitive (95%) and painful (45%) manifestations, moderately pronounced, the average score on the TSS scale was of 2.63 and 2.44, respectively; a correlation relationship between neurophysiological indices and subjective complaints (r-Pearson criteria value accounted of from 0.75 to 0.97) was revealed. Prenosological manifestations of electroneuromyography changes were detected in 5% of the examined subjects. Conclusion. The study of the functional state of peripheral nerves by using the method of stimulation electroneuromyography is an effective tool for the early diagnosis of occupational polyneuropathy.

This article analyzes the literature related to flaccid paresis and paralysis of the upper extremities in children during the first months of life. This pathology is a heterogeneous group of diseases with different etiopathogenesis. There are various courses of flaccid paresis and paralysis of the upper extremities in children: damage to the spinal cord, brachial plexus, peripheral nervous system to the level of the brachial plexus, and isolated damage to peripheral nerves. According to the time of occurrence, flaccid paresis and paralysis can be divided into three groups: antenatal, intranatal, and postnatal pathology. The main mechanism of occurrence of this pathology is intranatal trauma. More rare causes of flaccid paresis and paralysis of the upper extremities are antenatal conditions of dysplastic and traumatic origin, postnatal damage to the peripheral nervous system due to trauma or infection. Congenital contractures of the upper extremities combined with flaccid paralysis are connected with genetically determined diseases of the lower motor neurons and congenital myopathies, intrauterine injuries of the brachial plexus peripheral nerves. This article discusses the issues of topical and differential diagnosis of this pathology, the clinical picture suitable for each period of the childs life, and the prognosis of the disease. This research will be useful not only for neurologists, but also for specialists of related specialties: orthopedists, physiotherapists, and neonatologists for making correct the diagnosis, providing adequate treatment, and predicting its results.

Study Results

Introduction. Multiple studies of health state of workers in various economic branches of Russia revealed that peripheral nervous system diseases are among the most prevalent disorders. Th eir prevalence varies from 32.3 to 58 diseases per 100 examined workers, and they occupy usually fi rst place in the morbidity structure. Th ey are leaders among occupational diseases also. Objective. To determine features of occupational morbidity with peripheral nervous system diseases and its structure among workers in various economic branches of Bashkortostan Republic. Materials and methods. Th orough analysis covered occupational morbidity with peripheral nervous system diseases by separate branches, workers who are directly exposed to occupational hazards. Specifi c levels of the morbidity are defi ned by occupations, length of service in each economic branch. Results. Over 100 cases of occupational diseases are annually registered in Bashkortostan Republic. Over a half of them (54%) are diseases of peripheral nervous system. Th eir share among all occupational diseases tends to increase. Th e most prevalent type of peripheral nervous system diseases are radiculopathy (0.29 cases) and vibration disease (0.14 cases per 10,000 workers). Nearly all occupational diseases of peripheral nervous system are diagnosed in machinery building, metallurgic, mining, oil extracting industries, agriculture and building industry. In these economic branches, average of 16.59 cases per 10,000 workers exposed to occupational hazards is assigned to occupational peripheral nervous system diseases. Occupational diseases of peripheral nervous system diagnosed at average length of service of 23,3±3,4 years. Th e study results helped to determine specifi c economic branches associated with peripheral nervous system disorders development. At the highest risk of peripheral nervous system disorders are workers of mining (20,8‰0) and metallurgic (10,6‰0) industries. Conclusions. Peripheral nervous system diseases are the main causes of occupational morbidity, detailed according to specifi c economic branches and occupational groups, should be a basis of particular measures on lower impact of occupational risk factors, on prevention, health preservation, occupational and medical rehabilitation of the diseased.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Abstract Lesions of the peripheral nervous system (PNS), whether due to injury or illness, commonly result in residual symptoms and signs and, hence, permanent impairment. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) describes procedures for rating upper extremity neural deficits in Chapter 3, The Musculoskeletal System, section 3.1k; Chapter 4, The Nervous System, section 4.4 provides additional information and an example. The AMA Guides also divides PNS deficits into sensory and motor and includes pain within the former. The impairment estimates take into account typical manifestations such as limited motion, atrophy, and reflex, trophic, and vasomotor deficits. Lesions of the peripheral nervous system may result in diminished sensation (anesthesia or hypesthesia), abnormal sensation (dysesthesia or paresthesia), or increased sensation (hyperesthesia). Lesions of motor nerves can result in weakness or paralysis of the muscles innervated. Spinal nerve deficits are identified by sensory loss or pain in the dermatome or weakness in the myotome supplied. The steps in estimating brachial plexus impairment are similar to those for spinal and peripheral nerves. Evaluators should take care not to rate the same impairment twice, eg, rating weakness resulting from a peripheral nerve injury and the joss of joint motion due to that weakness.
