Therefore, welders should take personal protection
measures including, mask and safety goggles, and the process should be performed in well-ventilated areas, and use local-exhaust ventilation to remove fumes and gases at their source in still air. None of the authors of this manuscript has declared any conflict of interest. “
“A 65-year-old Guatemalan woman presented to the hospital with two days of nausea, vomiting, and diarrhea. Her medical history included CIDP, requiring 40–60 mg of prednisone daily. Twenty years previously, she emigrated from Guatemala but visited her native country annually. Medications on admission included prednisone 60 mg daily. She had a prior positive Strongyloides serology (titer 2.11 index value) and peripheral eosinophilia PLX4720 (3400/mm3) without documentation of prior anti-helminthic treatment. On presentation, her vital signs were: blood pressure
94/72 mmHg, heart rate 158 beats/min, respiratory rate 26 breaths/min, oxygen saturation 94% on 2 L/min O2 via nasal cannula, and temperature 37.0 °C. Dorsomorphin in vitro Physical exam revealed rigors, dry mucous membranes, clear lung fields, and suprapubic tenderness. Her WBC count was 22,000/mm3 (19% bands and 0% eosinophils). Urinalysis revealed 22 WBC/high powered field. In the emergency department, she received IV fluids, ciprofloxacin, metronidazole, and methylprednisolone 100 mg IV. She was admitted to the intensive care unit (ICU) and started on piperacillin-tazobactam. Phosphatidylethanolamine N-methyltransferase Methylprednisolone was discontinued and prednisone 30 mg twice daily was begun. Admission blood and urine cultures grew Escherichia coli. Stool studies were negative for enteric pathogens. On hospital day 2, her hemodynamic status improved and she was transferred to the
medical ward. On hospital day 5, she developed progressive hypoxemia. Contrast-enhanced chest CT identified small bilateral pleural effusions and diffuse perihilar and peripheral air space opacities. Chest X-ray on hospital day 8 demonstrated progressive bilateral infiltrates (Fig. 1). Bronchoscopy demonstrated blood throughout the tracheobronchial tree. Serial aliquots of bronchoalveolar lavage (BAL) fluid revealed persistently hemorrhagic fluid. She was intubated and transferred to the ICU. Repeat WBC count was 24,000/mm3 (7% bands and 13% eosinophils), platelets 348,000/mm3, and prothrombin time 13.9 s. Given bronchoscopic evidence of DAH, she was treated with 1 g of methylprednisolone daily for two days. Prior to methylprednisolone, she received a dose of oral ivermectin (200 mcg/kg). The following day, BAL fluid returned positive for Strongyloides stercoralis ( Fig. 2). Corticosteroids were discontinued. She received subcutaneous ivermectin (200 mcg/kg) every other day for 4 doses. Repeat bronchoscopy on hospital day 9 showed resolving hemorrhage. Serologies were negative for ANCA, anti-GBM, ANA, HIV, and HTLV-1.
