We present the case of a worker with occupational exposure to a pyrethroid insecticide who acutely developed nontransient third-degree heart block. In 2000, a 57-year-old male truck driver on his delivery route was accidentally exposed to pyrethroid insecticide being sprayed for West Nile virus containment. Both the driver and his vehicle were coated with the spray. The exposure was prolonged because he did not change his clothes until after his shift ended and he used the same contaminated truck for a week. Within days, he presented with a third-degree heart block, for which he was emergently treated, and a pacemaker was placed. He had no past history of arrhythmias. In the weeks thereafter, he also developed reactive airway dysfunction syndrome (RADS). In the second decade following the exposure, the patient replaced his pacemaker, confirming the permanent nature of his heart block. In addition to the persistence of his exposure-related RADS, he developed restrictive lung disease and was diagnosed with pulmonary interstitial fibrosis in the absence of established risk factors. The patient died in October 2019 from respiratory illness. Most previous reports of pyrethroid-related disorders are limited to acute exposures, in which transient symptoms predominate. To our knowledge, this is the first report of an exposed worker experiencing permanent third-degree heart block, as well as persistent respiratory findings, as possible shortand long-term sequelae of pyrethroid exposure.

Background Pyrethroid insecticides are widely used because of their low toxicity in humans. Spray-type pyrethroids are often formulated with kerosene as a carrier solvent, and inhalation of kerosene-containing products can lead to pneumonia and the formation of lung abscesses. We report a case of chemical pneumonia resulting in the development of a lung abscess due to the intentional inhalation of pyrethroids. Case presentation A man in his 50s in a psychiatric hospital for transient psychotic disorder attempted suicide during an overnight leave from the hospital. He drank sodium hypochlorite, put a nylon bag over his head, and sprayed pyrethroid insecticide inside the bag. He was found collapsed and was transported to our emergency room. On arrival, his SpO2 was 100% (on O2 at 10 L/min by mask), his circulation was stable, and his Glasgow Coma Scale score was E1V3M6, which improved to E4V5M6 in about one hour. A chest computed tomography (CT) scan showed ground-glass shading in both lungs. We diagnosed him as having pneumonia and started antimicrobial therapy. On day 13 of hospitalization, we found multifocal hypo-absorptive areas, and a diagnosis of lung abscess was made based on CT imaging, and antimicrobial therapy was continued. During the hospitalization, he expectorated bloody sputum. A contrast chest CT scan obtained on day 71 of hospitalization showed a pseudoaneurysm in the abscess cavity, for which we performed successful transcatheter coil embolization. On day 77, the abscess was shrinking, and he was transferred to another hospital for continued treatment. However, he again had bloody sputum and was transferred back to our hospital on day 113. Another contrast chest CT scan revealed the formation of a new aneurysm, and on day 114, we successfully performed coil embolization again, and he was transferred back to the other hospital on day 116. Conclusions Spray-type pyrethroid insecticides contain the organic solvent kerosene. Inhalation of kerosene has been reported in several cases of chemical pneumonitis leading to lung abscess. Clinicians should pay attention to kerosene contained in insecticides and the circumstances under which they are used. Early recognition and aggressive treatment can likely prevent severe outcomes.
