Lidocaine is the most commonly used local anesthetic (LA) agent in various dental as well as oral and maxillofacial procedures. Although rare, adverse effects and allergic reactions to lidocaine have been reported. In patients with suspected allergy to LA or a history of such reaction, careful history-taking and allergy testing should be performed to choose an alternative LA agent to avoid any adverse effects. Here, we present two cases of delayed hypersensitivity reaction to lidocaine, wherein the patients presented with erythema, edema, and itching. Intradermal testing confirmed allergic reaction to lidocaine, and the patients underwent successful dental treatment using an alternative LA agent. This report highlights the importance of allergy testing prior to LA use considering the serious consequences of allergy to these agents and describes the management of such patients using an alternative LA agent.

Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder characterized by numerous lentigines on the skin, with onset usually during early childhood. It is characterized by unilateral segmental distribution with sharp margins in one or more dermatomes. Conventional laser treatments result in several adverse effects, such as mottled pigmentary changes (hyper or hypopigmentation), especially in people of Asian descent. A 57-year-old man with PUL on the neck was treated with a high-fluence 1,064-nm Q-switched (QS) neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser. After 20 treatment sessions, the lesions markedly improved without adverse effects or recurrence. We suggest that high-fluence 1,064-nm QS Nd:YAG laser treatment is an effective and safe modality for PUL.

Local anesthetics are an essential part of pain control during dental treatment. Despite its effectiveness and safety, patients should constantly be aware of potential adverse effects, including allergic reactions. Allergic reactions to amide-type local anesthetics (LAs), such as lidocaine and mepivacaine, are rare compared to those to ester-type LAs. Herein, we report the case of a patient with a history of allergy to lidocaine and mepivacaine, with symptoms of itching, diffuse erythema of the wrists and hands, dizziness, and pectoralgia. This case report emphasizes the importance of collecting medical and dental histories of patients is necessary, and how an allergy test in the allergy and clinical immunology department helps select safe LAs for patients.

This study was carried out to find the adverse health effects of ozone by papers, the potential indoor sources of ozone by papers, and then the removal mechanism of ozone by experiments. The exposure of individuals to excessive levels of ozone both in the industrial and ambient environment is a continuing public health concern. Ozone indoors may play a role in generating secondary pollutants that may have adverse health effects. The removal efficiency of ozone was studied by (1) the effect of concentration on breakthrough time, (2) the effect of flow rate on breakthrough time, (3) the effect of adsorbent's weight on breakthrough time, (4) the effect of temperature on breakthrough time, (5) the application of Langmuir's isotherm equation in using activated carbon. The followings are the conclusions that were derived from this study. 1. In the effect of concentration on breakthrough time, the adsorption capacity of activated carbon was inversely proportional to ozone concentratuion (0.1, 0.2, 0.3 ppm). 2. In the effect of flow rate on breakthrough time, the service life of activated carbon was inversely proportional to flow rate (2, 8, 14l/min). 3. The difference in removal efficiency of ozone between weights(100 mg and 150 mg) was seen. And when weight of activated carbon was 100 mg and 150 mg, pressure loss was 4-5mmHg and 6-7mmHg, respectively. It is required to study relations among flow rate and adsorbent's weight and ventilation quantity, too. 4. Generally, Langmuir's equation, one of the oldest and most used frequently isotherm equation, applies to chemisorption. In case of ozone, when the weight of activated carbon was 70 mg and temperature 40, slope(1/a) was $6.25\times 10^{-1}$ and intercept(1/ab) was $1.9\times 10^{-4}$ (average r=0.94).

Objectives: The purpose of this study is to provide current the recent information on indium-related adverse health effects and the Korean indium-related industries. Methods: Peer review papers were searched in environmental, occupational and medical journals with the keyword of 'Indium' and 'ITO' and reviewed. To determine the indium related industries and indium consumption amounts, references and database were investigated and analyzed. In addition, field walk-through surveys and interviews were conducted in order to collect field data and to ascertain the field situation for the processes and industries. Results: A total of 10 cases of indium lung diseases have been reported in series since the first case reported in 2001. Seven cases were found in Japan, two cases in the United States, and one in China. No indium lung case has been reported yet in Korea, but it is believed that there are high potential risks among workers in indium-related industries. There are four categories in indiumrelated- industry; indium production and smelting, manufacturing of indium products such as ITO target, the production of thin films of flat panel display, and indium recovery industry. We found that all these types of industries are operating in Korea. Therefore, it is necessary for industrial hygienists to understand the processes and industries related to indium as well as the adverse health effects of indium. Conclusions: It was found that all four categories of indium-related industry from the indium production to recovery industry are active in Korea. However, the adverse health effects of indium are not well recognized. Therefore, it is believed that there is a high risks in indium-related industry, and it is necessary to make emergency interventions.
