Relation between obesity and bone mineral density and vertebral fractures in Korean postmenopausal women.
The traditional belief that obesity is protective against osteoporosis has been questioned. Recent epidemiologic studies show that body fat itself may be a risk factor for osteoporosis and bone fractures. Accumulating evidence suggests that metabolic syndrome and the individual components of metabolic syndrome such as hypertension, increased triglycerides, and reduced high-density lipoprotein cholesterol are also risk factors for low bone mineral density. Using a cross sectional study design, we evaluated the associations between obesity or metabolic syndrome and bone mineral density (BMD) or vertebral fracture. ⋯ In contrast to the effect favorable body weight on bone mineral density, high percentage body fat and waist circumference are related to low BMD and a vertebral fracture. Some components of metabolic syndrome were related to BMD and a vertebral fracture.

Effect of an air cleaner with electrostatic filter on the removal of airborne house dust mite allergens.
The effects of air cleaners on the removal of airborne indoor allergens, especially house dust mites (HDM), are still controversial. The objective of this study is to evaluate the effect of an air cleaner with an electrostatic filter on the removal of airborne mite allergens. ⋯ The electrostatic air cleaner can remove airborne HDM allergens and may be useful as a supplementary environmental control tool for HDM sensitized respiratory allergic patients.

The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. ⋯ In our study, there was no significant difference in the incidence between genders. The average age of the patients was 42.9 years. The incidence was highest in the fourth decade. There were no significant differences between the symptoms of odontogenic sinusitis and that of other types of sinusitis. However, almost all of the patients with odontogenic sinusitis had unilateral symptoms. Iatrogenic causes, which include dental implants and dental extractions, were the most common etiologic factors related to the development of odontogenic sinusitis. Therefore, a preoperative consultation between a rhinologist and a dentist prior to the dental procedure should be able to reduce the incidence of odontogenic sinusitis.

Effects of twice-daily injections of premixed insulin analog on glycemic control in type 2 diabetic patients.
Premixed insulin is effective to improve glycemic control; however, clinicians may be less likely to know which premixed insulin is appropriate for which patients. This study aimed to evaluate the effects of twice-daily injections of premixed insulin lispro on glycemic control in type 2 diabetic patients. ⋯ Switching from human protamine mixture 30/70 insulin to lispro mix50 twice-daily injection therapy in patients with high postprandial plasma glucose could improve their glycemic control and quality of life.

Sex difference of type 2 diabetes affected by abdominal obesity versus overall obesity.
This research compares the predictive value of the abdominal obesity indicator, waist circumference (WC), and the overall obesity indicator, body mass index (BMI), among men and women with regard to type 2 diabetes. ⋯ Both WC and BMI emerged as a measures of risk factors for type 2 diabetes among women while only WC emerged as a risk factor for diabetes among men.
