To study the effect of fluorine on the oxidative stress in coal-burning fluorosis, we investigated the environmental characteristics of coal-burning endemic fluorosis combined with fluorine content surveillance in air, water, food, briquette, and clay binder samples from Bijie region, Guizhou Province, southwest of China. The activities of antioxidant enzymes including copper/zinc superoxide dismutase (Cu/Zn-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and level of lipid peroxidation such as malondialdehyde (MDA) were measured in serum samples obtained from subjects residing in the Bijie region. Expression of the Cu/Zn-SOD gene was assessed by quantitative reverse transcriptase PCR (qRT-PCR).

Objective: This study used high-resolution PET to explore the pattern of DIP joint bone metabolism to test the hypothesis that the nail was functionally integrated with the bone, based on patterns of distal phalange (DP) bone metabolism in PsA compared with OA and normal joints.
Methods: A total of 234 DIP joints were scanned in 30 subjects (10 PsA, 10 OA, 10 healthy control) with [18F]fluoride using the quad-high-density avalanche chamber nano PET scanner. The images were assessed blinded to diagnosis and symptoms for site and intensity of increased [18F]fluoride uptake.

Exposure to hydrofluoric acid can cause severe skin damage via both corrosive and chemical means. Dermatologists should be aware of the various clinical presentations and knowledgeable of how to manage such patients. A case of a man with exposure of the hands after use of a consumer product containing hydrofluoric acid is presented.

Purpose: Reanalyses are frequently requested in forensic toxicology, and knowledge of the stability of drugs in biological samples is of major importance for the interpretation of the toxicological findings. Currently, the literature on stability of gammahydroxybutyrate (GHB) in blood samples from living subjects and in post-mortem blood is limited. The purpose of this study was to evaluate the long-term stability of GHB in both blood samples from persons suspected of drug use and post-mortem blood samples.

Hydrofluoric acid (HF) is commonly used for conditioning the glass ceramics either prior to cementation or for intraoral repair in prosthetic and restorative dentistry. The present study offers a review of chemical properties of HF used, highlight the possible hazardous effects of this agent, and to recommend the treatment approach for potential risks. Available published information documented in PubMed, Medline, and Picarta literature databases was reviewed.

With these recommendations the authors want to improve the acute therapy of eye burns based on the literature and clinical experience. Due to the lack of studies with high evidential value we base these recommendations on the results of experimental work and reports of successfully treated eye burns. A development of this document by systematic research is necessary.

This is a case report of decontamination and treatment of a 70% hydrofluoric acid (HF) dermal splash injury. A worker was splashed with 70% HF, sustaining approximately 10% TBSA first- to third-degree chemical skin burns of the face, trunk, and left thigh and leg. Initial decontamination involved water rinsing, removal of contaminated clothing, more water rinsing, topical application of magnesium oxide, and administration of intravenous narcotics for management of severe pain.

The presence of environmental fluoride and its impact on human health is well documented. When consumed in adequate quantity, fluoride prevents dental caries, assists in the formation of dental enamels, and prevents deficiencies in bone mineralization. At excessive exposure levels, ingestion of fluoride causes dental fluorosis skeletal fluorosis, and manifestations such as gastrointestinal, neurological, and urinary problems.

Background And Objective: Chlorhexidine (CHX) is the most tested and leading oral antiseptic agent. Zinc as an active ingredient has shown additive and synergistic effect and when Sodium fluoride (NaF) was used it failed to show added effectiveness and the combined effect of NaF and Zinc chloride (ZnCl2) both as active ingredients has never been evaluated. The present study assessed the effectiveness of active ingredients and to compare the frequency of adverse events occurring with traditional CHX and CHX+NaF+ZnCl2.

Background: Although hydrofluoric (HF) acid burns may cause extensive tissue damage, severe systemic toxicity is not common after mild dermal exposure.
Case: A 36-year-old worker suffered a first-degree burn of 3% of his total body surface area as a result of being splashed on the right thigh with 20% HF acid. Immediate irrigation and topical use of calcium gluconate gel prevented local injury.

Background: Hydrofluoric acid (HF) is a small and partially dissociated acid (pK(a) 3.2), able to deeply penetrate into human skin in addition to the corrosiveness of the hydrogen ion (H(+)) and the toxicity of the fluoride ion (F(-)). However, there has been a lack of experimental studies to objectively characterize the results of human HF skin exposure decontamination.

Background: Hydrofluoric acid (HF) is particularly dangerous due to the potential for systemic effects and induction of severe skin necrosis through two mechanisms: corrosiveness and local tissue toxicity. In addition, because it is only partially dissociated (pK(a) 3.2), it is capable of penetrating deeply into tissues.

Exposure to household products is very common, but in industrialized countries severe or fatal poisoning with household products is rare today, due to the legal restriction of sale of hazardous household products. The big challenge for physicians, pharmacologists and toxicologists is to identify the few exceptional life-threatening situations where immediate intervention is needed. Among thousands of innocuous products available for the household only very few are hazardous.

Objective: To study on the fluorine capture effect of calcium based coal briquette with fluorine capture additive in coal-burning fluorosis area.
Methods: Add proper proportions of calcium based fluorine capture additive in high fluorine coal for making coal briquette were added, and were added the fluorine in coal cinder in order to reduce its emission. Meanwhile, to determine the composes of coal briquette were added, the percentage of fluorine in coal cinder and the concentration of fluoride, sulfur dioxide and PM10 were determinated, to evaluate the effect of fluorine capture and the level of door air pollution.
