Background: Glyphosate and glufosinate use widely used as herbicide ingredients. There have been several reported cases of chemical burns caused by dermal exposure to glyphosatecontaining herbicide, and patients in these cases were discharged without fatal complications.There were no cases of severe symptoms due to non-oral exposure of glufosinate-containing herbicides. Here, we report a case of fatality accompanied with severe chemical burns in an 81-year-old man who did not wash his skin for more than 48 hours after dermal exposure to herbicide containing glyphosate and glufosinate with surfactant (HGlyGluS).Case presentation: An 81-year-old male with no underlying disease was admitted to the emergency department (ED). He had sprayed HGlyGluS with a manual knapsack sprayer 3 days ago and had not wash away the herbicide. On arrival, he was drowsy and had multiple severe corrosive skin lesions. Skin necrosis (10 × 15 cm) on the right shoulder and skin lesions with subcutaneous fat exposure (15 × 20 cm) on the right thigh were observed. Although he was treated including continuous renal replacement therapy, antibiotic apply, debridement operations, and so on, he was unable to recover and expired. Conclusions We suggest that prolonged dermal exposure to HGlyGluS induces fatality.Further studies including prolonged dermal exposure and ingredients of surfactants should be carried out. Also, it is necessary to educate farmers that it is very important to wash immediately after dermal exposure to pesticide.

PURPOSE: Disturbances of mineral metabolism are common during the course of chronic kidney disease (CKD) and may lead to serious and debilitating complications unless properly treated. The purpose of this study is to quantify the prevalence of secondary hyperparathyroidism and vitamin D deficiency in non-dialysed chronic kidney disease 3, 4, and 5 in Korea. METHODS: This study included patients who had documented eGFR<60 mL/min/1.73m2 and non-dialysed and had not received any vitamin D compounds. eGFR was calculated by simplified MDRD (Modification of Diet in Renal Disease study) equation. Blood samples were collected for serum creatinine, calcium, phosphate, intact PTH and vitamin D metabolites between May 2006 and April 2007. RESULTS: According to K/DOQI guideline, the prevalence of hyperparathyroidism was 46.9% (15/32) in stage 3 (iPTH>70 pg/mL),45.9% (17/37) in stage 4 (iPTH>110 pg/mL) and 20.5% (9/44) in stage 5 patients (iPTH>300 pg/mL). The prevalence of 25-hydroxyvitamin D deficiency (25(OH)D3<15 ng/mL) was 86.2% (25/29) in stage 3, 75.7% (28/37) in stage 4 and 88.4% (38/43) in stage 5. There was a negative correlation between eGFR and intact PTH (r=-0.531, p=0.000) and a positive correlation between eGFR and 1,25-dihydroxyvitamin D (r=0.587, p=0.000). Conclusions: So far as non-dialysed CKD patients in Korea are concerned, quantification of the prevalence of abnormality of intact PTH and vitamin D deficiency has been described in this study. More research should be conducted in the future in a prospective, multi-center community cohort study, of which subjects include the early stages like CKD 1 and 2.
