Two Cases of Allergy to Insulin in Gestational Diabetes.

Allergic reaction to insulin is uncommon since the introduction of human recombinant insulin preparations and is more rare in pregnant than non-pregnant females due to altered immune reaction during pregnancy. Herein, we report two cases of allergic reaction to insulin in gestational diabetes that were successfully managed. One case was a 33-year-old female using isophane-neutral protamine Hagedorn human insulin and insulin lispro.

Supportive management resolved a colonic intramural hematoma in an anticoagulant user.

Intramural hematomas of the colon are rare. Intramural hematomas of the gastrointestinal tract often result from blunt trauma, although they may also occur spontaneously in patients taking anticoagulants or those with blood dyscrasia. Affected patients present with abdominal pain and lower gastrointestinal bleeding, as well as occasional signs of intestinal obstruction.

Necessity for a national carcinogen list in Korea, based on international harmonization.

Cancer has been the leading cause of death in Korea for the last 30 years. Cancer patients' 5-year survival rate between 2005 and 2009 was 62.0%, representing a highly advanced standard of care, as much as developed countries in the EU and the US.

The "Chair Campaign" in Korea: an alternative approach in occupational health and safety for service workers.

In spite of the increasing number of service workers in Korea, their occupational health and safety concerns have largely been neglected. It is in this context that the Chair Campaign, which lasted four months, was launched as an alternative occupational health approach for service workers. The campaign succeeded in getting wide public support, bringing about a special inspection by the Ministry of Labor.

An assessment of dust, endotoxin, and microorganism exposure during waste collection and sorting.

This study was conducted to assess inhalation exposure to dust, endotoxin, and microorganisms (including viable bacteria, Gram-negative bacteria [GNB], and fungi) during waste collection and sorting; to identify factors affecting this exposure; and to estimate the gastrointestinal exposure to microorganisms. A total of 48 or 49 workers involved in collecting and sorting waste from households or the street were studied. Each worker carried two personal samplers in which filters were placed in the breathing zone for estimation of inhalation exposure.

Vaporization and Conversion of Ethanolamines used in Metalworking Operations.

Objectives: This study examined how ethanolamines (EAs) with the same functional alcohol group (HOCH(2)CH(2)), such as mono-EA (MEA), di-EA (DEA), and tri-EA (TEA), in water-based metalworking fluids (wbMWFs) are vaporized, condensed, and transformed by heat generated during metalworking.

Methods: Two types of experimental apparatus were manufactured to achieve these objectives.

Results: Vaporization tests using a water bath showed that the vaporization rate increased markedly from 0.

Loss of straight metalworking fluid samples from evaporation during sampling and desiccation.

Straight metalworking fluids (MWFs) were used to evaluate the potential for the loss of MWF mass from filters. Two methods were used to study the stability of MWF mass on filter media. The first was to spike known amounts of MWF onto polyvinyl chloride (PVC) filters, store the filters over silica gel desiccant, and take repeated gravimetric measurements of the filters at intervals of 1, 2, and 3 days.
