Lead poisoning symptoms
Lead usually leads to chronic poisoning, as it can be kept in a tissue for a long-time, especially in the parenchymatous organs and bones. The common symptoms of lead poisoning: “lead” skin color, lead border at the gums, the change of blood (reticulocytosis more than 6-8%, basophilic stippling of red blood cells), increasing the stomas in urine. The defeat of the nervous system is typical, and occurs often.
Lead poisoning is characterized by the following neurological syndromes:
1. Asthenic syndrome (headaches, dizziness, non-system nature, physical and mental fatigue, lethargy, a violation of sleep, emotional lability, narrowing the range of interest).
2. Lead encephalopathy (a significant memory impairment, intense headaches, reduction of criticism to your state, psychosensory disturbances and breaches of perceptions in the form of visual, auditory and tactile hallucinations, hyperkinesis, ataxia, defeated craniocerebral nerves, the phenomenon of temporal epilepsy, lead meningopathy).
3. Lead colic occurring as a kind of vegetative crisis (Cramping pain, disruption of the intestine, vomiting, tachycardia, rising blood pressure, elevated levels of catecholamine’s in the blood).
4. Lead palsy – the most severe and typical syndrome. The paralysis may be myogenic (toxic myositis) and neurogenic (neurotic and pre-nerves) character. The most commonly affects the hands and fingers extensors (coil brush), sometimes with damage of the foot extension.
In this case, Aran – Dyshein syndrome can develop (with weakness and atrophy of small hand muscles). The right hand usually suffers graver. Brahial type appears muscles of proximal hand sections. Occasionally, occur a generalized type of injury with the hands and feet paresis or paralysis. In severe cases, the process involved eye-motive and facial nerves.
