The Investigation Of Dermatitis Diagnosis And Treatment And Contact Status Of Guangzhou Pesticides

The first part: the present situation of pesticide exposureObjective:This study through to the pesticide dermatitis disease situation investigation, trying to summarize several clinical characteristic of dermatitis, for further standardization, standardization of the diagnosis and treatment of the pesticide dermatitis provide advice and improve the prognosis of patients. For pesticide dermatitis, epidemiological studies at the same time, reduce the incidence of pesticide poisoning and the case fatality rate.Methods:Choose a hospital service in guangdong province within the scope of the country in September2012to August2013farmers in exposure to pesticides as the research object. Using cluster sampling method, according to the unified formulation of the questionnaire, by the training of medical and health personnel to take the way of household surveys, door to door asking the village each pesticide exposure after fill in the questionnaire, understand pesticides dermatitis incidence and contact status of pesticides. Results:Survey of the country, mainly planting crops such as rice, vegetables, a total of216households,627people,272people engaged in agricultural labourers; Exposure to pesticides, a total of201people, of whom69men, aged18-70, an average of46.5+/-22.4years, pesticide exposure quantity is:3000-15000-ml/door.62degree structure: elementary school, illiteracy19people, other for junior middle school or high school culture; Exposure to pesticides, total of201people in contact with pesticides organophosphate class139,58people, carbamate nereid toxin class39m, deinsectization strain25m, other21m;46people,201people in pesticide dermatitis incidence was22.89%,41people appear in1to3hours after contact, main show is the itch, erythema, blister sample, urticaria, skin, pimples, etc; The majority of patients after cleaning the skin, the symptom is reduced in1to2days rest, didn’t go to hospital for treatment, only7cases go to hospital for treatment such as hormones, antihistamines, antibiotics.Conclusion:(1) pesticides dermatitis occurs obvious seasonal, incipient symptoms of lack of specificity, easy cause to ignore.(2)Somewhere through the identification of a productive and non-productive most harmful pesticides, pesticide in the strict management or for finding alternative pesticides, reduce or eliminate dangerous pesticide exposure, can reduce the incidence of productive pesticide dermatitis and to reduce the mortality of unproductive pesticide poisoning. The second part:the treatment of dermatitis pesticidesObjective:To explore the diagnosis and treatment of pesticide dermatitis method, for further standardization, standardization of the diagnosis and treatment of the pesticide dermatitis provide advice and improve the prognosis of patients. And puts forward Suggestions for the reasonable use of pesticides, reduce the incidence of pesticide poisoning and the case fatality rate.Methods:Collected from our hospital treatment of pesticide in four years the onset of patients with dermatitis, examination, treatment cases. All cases after receiving advice repeatedly wash skin with soap and water, or with weak alkaline cleaning(Dichlorvos class contact dermatitis patients disabled alkaline cleaning liquid, will accelerate absorb poison, using plenty of water for irrigation). Disable the hot water washing or with alcohol to swab, lest make the skin blood vessels, promote absorb poison. At the same time give hormone, antihistamines; When it is necessary to add with antibiotics and dexamethasone, vitamin C, azithromycin, levofloxacin, sago for reading therapy, etc. Blister after the big infusion treatment, the skin inflammation net ointment cha with0.02%nitrofural wet apply alternates, apply2%gentian violet liquid after drying. Acetyl cholinesterase activity decline is combined with atropine and phosphate-solubilizing injection, etc.Results:Were collected in our hospital between January2009and December2009the pesticide data of52cases of dermatitis patients,36cases of men, women,16cases, aged18-65, an average of36.2+/-11.24years old. Including49cases caused by productive and non-productive cause3cases. Organic phosphorus pesticide categories:46cases, deinsectization strain type6cases, the incubation period, less than3hours,42cases,8cases of3to6hours,2cases of more than6hours. Clinical manifestation: the itch in49cases, erythema, blister39cases,10cases of urticaria sample was detected, papule6cases,5cases with system performance, including increased leukocyte38cases,4cases were lower, blood cholinesterase activity dropped6cases.All52patients have been cured after treatment, all cases3～10d the local convergence of the wound,5～20d dermatitis recovery; No pigmentation, no scar growth. The productive causes pesticide dermatitis patients caused skin healing time was7.73+/-4.12d, unproductive causes skin healing time of pesticide dermatitis patients16.73+/-4.12d, both in patients with skin healing time differences statistically significant (P<0.05).Conclusion:The productive pesticide poisoning is clinical treatment, focused on targeted treatment, can improve the cure rate.
