[Hand-arm vibration syndrome in caisson miners].

Authors examined 43 caisson-miners with symptoms of the upper extremities because of suspicion of hand-arm vibration syndrome. Also vibration measurements were performed on the pneumatic hammer used by the workers. The acceleration of the vibration exceeded 2.5-3.5 times the maximum allowable level according to the ISO 5349. Symptoms and signs of hand-arm vibration syndrome were found in 39 cases (90.7%). The vascular, peripheral neurological and locomotor system of the upper extremities were affected in similar frequency: 54.8; 51.6 and 51.2%, respectively. The most common angiological alteration was the Raynaud's phenomenon. Neurologically predominated the tunnel syndromes. Among the osteoarticular lesions the degenerative phenomena were the most frequent. In most cases more than one pathological alteration occurred. Fatigue fracture of the spinous process of vertebra D. I. appeared in one single case, degenerative changes of cervical spine in 34 patients (79.1%). The very common occurrence of the locomotor alterations and tunnel syndromes respectively can be explained probably also by the high physical stress required by this profession. The detailed examination of the locomotor system is very important by the periodical screening of the caisson-miners.

Lead intoxication epidemic caused by ingestion of contaminated ground paprika.

OBJECTIVE: Report of a lead intoxication epidemic caused by ingestion of contaminated ground paprika. DESIGN: Retrospective study of case histories. SETTING: Institutional, toxicological and medical referral center for ambulatory and hospitalized care. PATIENTS: One hundred forty-one adults consumed paprika contaminated with lead tetroxide (red lead). INTERVENTIONS: Intravenous calcium disodium versenate (edetic acid). MAIN OUTCOME MEASURES: Measurement of zinc protoporphyrin:heme ratio of whole blood and the blood lead level. EDTA mobilization test. RESULTS: Fifty-three patients had symptoms and signs of lead poisoning. The most common clinical signs were colic and/or anemia. Twenty-six persons showed increased lead absorption without clinical symptoms and signs. Chelation therapy with calcium disodium versenate resulted in complete clinical recovery. CONCLUSION: Lead-contaminated ground paprika, not previously described as a cause of alimentary lead intoxication, may cause symptomatic poisoning.

[Hand and arm vibration syndrome caused by mechanical screw driver].

Authors performed angiological, neurological and radiological examination of 17 persons working with power screw-drivers. Vibration measurement of the tools was made too. 10 patients had symptoms and signs corresponding to the hand-arm vibration syndrome. The vibration of some tools exceeded the maximal allowable acceleration level according to ISO 5349. On the ground of the results authors conclude that some power screw-drivers can cause hand-arm vibration syndrome. The importance of choosing of the right tools and the significance of the periodical examinations are underlined in the prevention of the damages.

[Vibration-induced Raynaud phenomenon caused by an electric hedge trimmer].

Authors observed Raynaud's phenomenon verified by cold-provocation test and measuring finger systolic blood pressure on a man working with bush cutter equipment installed on a tractor. Vibration measurements showed acceleration superior to maximal allowable level. Other causes of a secondary Raynaud's phenomenon were excluded by means of detailed internal examination. On the ground of the exposure data and lack of other ethiological factors the authors think that the patient had vibration-induced Raynaud's phenomenon. For prevention they proposed the diminishing of the daily exposure time and periodical medical examinations. They want to draw the attention for this sort of exposure.

[An undying civilization damage: lead poisoning].

The authors summarise the history, the sources, the pathophysiology, the symptoms and signs, the diagnostic methods, the differential-diagnostic possibilities, the therapy and prevention of the lead poisoning. They suggest that besides the classical professional and alimentary sources the environmental pollution caused first of all by leaded petrol plays a more and more important role in the lead exposure of the people. They draw the attention of the physicians to the lead intoxication as a possible cause of abdominal pain and/or anemia.

Prevalence of thyroid dysfunction in different geriatric subpopulations from a moderately iodine-deficient Hungarian region. Comparative clinical and hormonal screening.

The aim of this study was to investigate the prevalence of thyroid dysfunction in different geriatric subpopulations from a moderately iodine-deficient Hungarian region and to compare the efficacy of clinical versus hormonal screening. A screening study was done on 279 chronically ill geriatric patients (Group I) and 256 consecutive hospital admissions over 60 years of age (Group II). The method of clinical screening was different from those used so far: the object was not to search for symptoms of hypo- or hyperthyroidism but to find any sign justifying a further thyrotrophin-based biochemical evaluation, i.e. history of thyroid disease or goitre or any clinical sign of hormonal dysfunction. The rates of overt hypothyroidism, overt hyperthyroidism, subclinical hypothyroidism and subclinical hyperthyroidism discovered by the hormonal screening were 2.9, 1.1, 3.6 and 5.7% in Group I and 3.5, 2.3, 3.9 and 2.0% in Group II. The sensitivities of the clinical screening to suspect overt or overt+subclinical dysfunctions were, respectively, 0.82 and 0.64 in Group I and 1.0 and 0.7 in Group II (or 0.67 and 0.4 if the clinical investigation was done not by an endocrinologist but by the medical attendants). A primarily clinical investigation-based screening would have spared 171/279 thyrotrophin estimation in Group I and 161/256 in Group II, but would have missed 2/11 overt and 11/26 subclinical dysfunctions in Group I. In Group II, no overt but 9/15 subclinical dysfunctions would have been lost in this way. Our approach of a clinical investigation-based screening was rather efficient in suspicion of overt thyroid dysfunction but failed to detect many cases with subclinical dysfunction.(ABSTRACT TRUNCATED AT 250 WORDS)

Vibration disease.

Today, in this age of technology, vibration caused by machinery is an almost universal hazard. Vibration transferred from a machine to the human body may cause discomfort, a reduction of performance, and even injury. Vibratory manual tools may cause damage to the circulatory system of the upper extremities (Raynaud's syndrome), to the peripheral nerves (peripheral neuropathy), and to the bones and joints (aseptic necrosis, fatigue fractures, degenerative joint disease). Vehicles and machines causing floor vibration cause degenerative disc disease of the lumbar spine. The pathogenesis of vibration injuries is still not completely clear and there is no effective treatment. Some of the abnormalities are irreversible and may cause permanent decrease of working ability, and even unemployment. This is why prevention is so important. Prevention is complex, including technical and organizational measures, use of individual protective clothing and footwear, and medical supervision both before and during employment. Workers who are exposed to vibration should be protected against other aggravating factors such as cold and noise, etc. Vibration-induced injuries are recognized in law in many countries as grounds for financial compensation. Their cost to industry is rising and, unless a means of prevention or cure is found, will continue to do so in the foreseeable future.

[Arthrosis of the distal radio-ulnar joint in workers using motorised saws (author's transl)].

Vibration-induced changes in the distal radio-ulnar joint were analysed by comparing workers using motorised saws (978 cases) and a control group. The following are the essential findings: 1. Exposure to vibration causes characteristic changes in the distal radio-ulnar joint, particularly on the left, consisting of osteophytosis, deformity and cystic rarefaction. 2. The frequency of the arthrosis is related in a statistically significant manner to a) length of exposure, b) age. 3. The subjective complaints of numbness, weakness and pain can, to some extent, be related to the radio-ulnar arthrosis. 4. Vibration is not the only factor in the genesis of the degenerative process of the distal radio-ulnar joint; ordinary use and stress can cause similar changes, although to a much less marked extent. The aetiological role of local vibration as a factor in causing the arthrosis has been confirmed.

[Arthropathy as a late result of trauma (author's transl)].

On the basis of 5 cases the syndrome of post traumatic arthropathy is described. Like its other forms it shows radiographyically a high degree of osteolysis, fragmentation and para-articular calcification of soft parts. The picture is similar to that of syringomyelia and tabes. If trauma occurs in childhood there will also be developmental retardation. One has to assume that trauma may be responsible for these isolated arthropathies at its site. Since the further course corresponds to that of a neurogenous arthropathie it is likely that in these cases there is an underlying disturbance of the relationship between nervous system and bone and joint which, so far, cannot be proved clinically.
