In a survey of occupationally acquired disease in workers at a pesticide plant, we found that 11 (11%) of 102 workers had been hospitalized for illness related to chemical exposures; highest hospitalization rates occurred in packaging (27%), production (22%), and maintenance (9%) workers. Commonest causes of hospitalization were intoxication by the carbamate pesticide methomyl [1-(methylthio)ethylideneamino methyl carbamate], a reversible cholinesterase inhibitor, and methemoglobinemia following exposure to 3,4-dichloroaniline. On clinical evaluation, five (46%) of 11 packaging workers, the group with the highest exposure to methomyl, had experienced blurred vision or pupillary constriction. Seventeen (61%) of 28 production workers with exposure to dichloroaniline and propanil (3'4'-dichloropropionanilide) had chloracne, an acne-form dermatosis caused by the contaminant tetrachlorazobenzene in propanil and dichloroaniline. The chloracnegenic potentials of propanil and dichloroaniline were verified by rabbit ear tests. These findings reemphasize the hazards inherent in the the manufacture and formulation of pesticides and herbicides.

Sweet's syndrome is rare acute febrile neutrophilic dermatosis whose onset is either idiopathic or associated with other underlying conditions, such as infections, autoimmune diseases, pregnancy, use of certain medications, or malignancy. We report the case of a young male with known history of ulcerative colitis and abrupt onset of high fever, malaise, blurred vision and eruption of painful erythematous nodules and papules, localized on the head, neck, trunk and upper limbs. Ophthalmological examination established the diagnosis of anterior uveitis. Inflammatory markers were positive. Histological examination of skin lesions revealed a dense neutrophilic infiltrate of the dermis. Clinical, laboratory and histological findings were suggestive for the diagnosis of Sweet's syndrome and uveitis on a background of ulcerative colitis. Systemic and ophthalmic administration of corticotherapy leads to a prompt resolution of symptoms and inflammatory syndrome. The particularity of this case is the occurrence of two simultaneous extraintestinal manifestations in a young male with inflammatory bowel disease and colonic involvement. Although a relatively rare condition, Sweet's syndrome should be considered as a differential diagnosis in patients with acute onset of high fever and skin rash, as it may have notable internal involvement and can be easily treated.

Cicatricial Pemphigoid is a subepithelial bullous dermatosis which essentially involves the mucous membranes with cicatricial evolution We report the case of a 66-year old patient hospitalized with erosive gingivitis associated with dysphagia, dyspnea and blurred vision. Dermatologic examination showed erosive lesions involving the palate and the pharynx. Ophthalmologic examination showed symblepharons, ectropion and bilateral cataract. Gingival biopsy revealed a necrotic detachment of the buccal epithelium. Direct immunofluorescence showed linear IgA deposit at the dermo-epidermal junction. Indirect immunofluorescence test was negative. The diagnosis of cicatricial pemphigoid was confirmed. Esophagogastroduodenoscopy objectified double stenosis of the esophagus. Nasopharyngeal and bronchial endoscopy showed ulceration of the epiglottis, hypopharynx, pharynx and bronchial tree. The patient was treated with Solumedrol bolus corresponding to 0.5mg/kg/day prednisone associated with 100mg/day disulone. The patient showed a favorable early clinical outcome complicated because of the aggravation of dysphagia and esophageal stenosis after 2 months. Our case study is singular due to the occurrence of a cicatricial pemphigoid in a male patient with a serious clinical picture due to lesions extending to conjunctival, oral, nasal, esophageal and bronchial mucous membranes associated with direct immunofluorescence only showing IgA deposit.
