    ABSTRACT: Prescribing potentially harmful drugs and omitting essential drugs to older patients is a common problem because they take so many medications. In this study, our goal was to identify potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) using Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Screening Tool to Alert doctors to the Right Treatment (START) criteria to improve proper prescription and reduce improper prescription. Enrolled in this study were 117 patients older than 65 years old who were hospitalized at Inha University Hospital in Incheon due to pneumonia from January 2012 to March 2012. Patient data, including medical histories, current diagnoses, current medications, and biochemical data were recorded from electronic records. STOPP and START were applied to their clinical datasheets. STOPP criteria identified 24 patients who had 29 PIMs. Most potential inappropriate prescribing was of cardiovascular medications, followed by drugs whose primary effect is on the urogenital system and gastrointestinal system. START criteria identified 31 patients who had 46 PPOs. The cardiovascular system drugs comprised most of the PPOs. No PPOs were identified under the central nervous system criteria. Given the current Korean medical system conditions and considering the many clinically important situations when prescribing drugs, STOPP/START criteria are not absolute criteria to prevent improper prescription, but sagacious usage of these standards can help physicians to prescribe properly in clinical practice.

    ABSTRACT: To the Editor: Purple urine bag syndrome (PUBS) is a unique phenomenon mostly seen in patients with dementia, and in 1 report, 27% of the elderly patients in a geriatric hospital who required urinary catheterization for a long period developed PUBS.1 Thus, it is not rare for geriatric clinicians to encounter PUBS, and confirming the management of this phenomenon is important. Drs Ben-Cherit and Munter2 presented a case of PUBS in which urine culture was ordered and replacement of the catheter was recommended.

    ABSTRACT: Metabolic syndrome is a risk factor of cardiovascular diseases. Previous studies have reported that low serum magnesium levels are related to high blood pressure, diabetes mellitus and dyslipidemia. However, there have been few studies on association between serum magnesium levels and metabolic syndrome. Therefore, we investigated the relationship between them in this study.

    ABSTRACT: To investigate whether smoking and the smoking status are predictors of the incident impaired fasting glucose (IFG) or type 2 diabetes in Korean men. A cohort of 1,717 Korean men without IFG or diabetes, who underwent annual periodic health examinations for 4 years (2002-2006), were retrospectively investigated. IFG and diabetes were defined as a serum fasting glucose concentration of 100-125 mg/dL and more than 126 mg/dL, respectively. Cox's proportional hazards model was used to evaluate the association between smoking and development of IFG or type 2 diabetes. A total of 558 cases (32.5%) of incident IFG and 50 cases (2.9%) of diabetes occurred. After controlling for the potential predictors of diabetes, the relative risk for IFG, compared with the never smokers, was 1.02 (95% CI=0.88 to 1.19) for the ever-smokers, 0.96 (95% CI=0.79-1.16) for those who smoked 1-9 cigarettes/d, 1.15 (95% CI=1.01 to 1.30) for those who smoked 10-19 cigarettes/d, and 1.31 (95% CI=1.10 to 1.57) for those who smoked 20 or more cigarettes/d (the P value for the current smokers was only p<0.002). The respective multivariate adjusted relative risks for type 2 diabetes, compared with the never-smokers, were 1.07 (95% CI=0.64 to 1.92), 1.47 (95% CI=0.71 to 3.04), 1.84 (95% CI=0.92-3.04), and 1.87 (95% CI=1.13-3.67), respectively (the P value for the current smokers was only p=0.004). The smoking status and the number of cigarettes smoked daily are associated with an increased risk for developing IFG or type 2 diabetes in Korean men.

    ABSTRACT: To compare the efficacy of acupuncture needling and 0.5% lidocaine injection of trigger points in myofascial pain syndrome of elderly patients. Thirty nine participants with myofascial pain syndrome of one or both upper trapezius muscles were randomised to treatment with either acupuncture needling (n=18) or 0.5% lidocaine injection (n=21) at all the trigger points on days 0, 7 and 14, in a single-blinded study. Pain scores, range of neck movement, pressure pain intensity and depression were measured up to four weeks from the first treatment. Local twitch responses were elicited at least once in 94.9% of all subjects. Both groups improved, but there was no significant difference in reduction of pain in the two groups at any time point up to one month. Overall, the range of cervical movement improved in both groups, apart from extension in the acupuncture needling group. Changes in depression showed only trends. There was no significant difference between acupuncture needling and 0.5% lidocaine injection of trigger points for treating myofascial pain syndrome in elderly patients.

    ABSTRACT: Although many Koreans travel each year to countries where malaria is present, few data are available on the knowledge, attitudes, and practices of Koreans with regards to malaria. The study was conducted in the departure lounge of Incheon International Airport in May 2006. A 22-item questionnaire was administered to Korean travelers whose travel destination was India. Of 188 respondents, 24% had sought pretravel health information. Independent predictors for seeking pretravel health information were the following: being a Korean woman, longer duration of travel, planning to travel independently or to a rural area, and perceived risk of malaria. A total of 47% of travelers answered that they had not perceived any risk of malaria, and only 7% of travelers carried malaria prophylaxis. There is an urgent need for increased awareness about travel-related infectious diseases (especially malaria) among Korean travelers, and they should be encouraged to seek pretravel health information.

    ABSTRACT: To compare the efficacies of dry needling of trigger points (TrPs) with and without paraspinal needling in myofascial pain syndrome of elderly patients. Single-blinded, randomized controlled trial. Forty (40) subjects, between the ages of 63 and 90 with myofascial pain syndrome of the upper trapezius muscle. Eighteen (18) subjects were treated with dry needling of all the TrPs only and another 22 with additional paraspinal needling on days 0, 7, and 14. At 4-week follow-up the results were as follows: (1) TrP and paraspinal dry needling resulted in more continuous subjective pain reduction than TrP dry needling only; (2) TrP and paraspinal dry needling resulted in significant improvements on the geriatric depression scale but TrP dry needling only did not; (3) TrP and paraspinal dry needling resulted in improvements of all the cervical range of motions but TrP dry needling only did not in extensional cervical range of motion; and (4) no cases of gross hemorrhage were noted. TrP and paraspinal dry needling is suggested to be a better method than TrP dry needling only for treating myofascial pain syndrome in elderly patients.

    ABSTRACT: To compare the efficacies of an intramuscular stimulation technique and 0.5% lidocaine injection to trigger points in myofascial pain syndrome. Forty-three people with myofascial pain syndrome of the upper trapezius muscle. Twenty-two subjects were treated with intramuscular stimulation and another 21 with 0.5% lidocaine injection at all the trigger points on days 0, 7 and 14. Intramuscular stimulation resulted in a significant reduction in Wong-Baker FACES pain scale scores at all visits and was more effective than trigger point injection. Intramuscular stimulation also resulted in significant improvement on the Geriatric Depression Scale - Short Form. Local twitch responses occurred in 97.7% (42/43) of patients. All the passive cervical ranges of motion were significantly increased. Post-treatment soreness was noted in 54.6% of patients in the intramuscular stimulation group and 38.1% in the trigger point injection group, respectively, and gross subcutaneous haemorrhage (> 4 cm2) was seen in only one patient in the trigger point injection group. In managing myofascial pain syndrome, after one month intramuscular stimulation resulted in more significant improvements in pain intensity, cervical range of motion and depression scales than did 0.5% lidocaine injection of trigger points. Intramuscular stimulation is therefore recommended for myofascial pain syndrome.
