Patterns of using complementary and alternative medicine by stroke patients at two university hospitals in Korea.

This study measured the prevalence of complementary and alternative medicine (CAM) use among Korean stroke patients. Questionnaire-based 20-min interviews were conducted at the hospitals by a trained nurse after an outpatient visit. It included questions on demographic information, clinical information and the utilization of CAM. Of 304 stroke-patient respondents, 164 (54%) had used CAM, of which 66% had started taking CAM products following suggestions from family members and other relatives. Of the 57% of users who felt that CAM was effective, 84% considered that it improved the symptoms of stroke and 16% felt it was effective in achieving psychological relaxation. Of the eight CAM categories used by respondents, 92% used traditional Oriental medical treatments, 36% used plant- and animal-derived over-the-counter health care products, 24% used minerals and vitamins, and 11% used manual therapies. The majority of stroke patients (68%) were trying a new type of CAM, and half of the respondents (45%) relied on the knowledge of their general practitioner about CAMs when deciding whether to use them. Most of the stroke patients in this study used CAM, and a half of them reported beneficial effects. Despite the presence of adverse side effects, they tended to be used without discussion with chief physicians, and hence physicians should be actively involved in the usage of CAM.

Use of complementary and alternative medicine by rheumatoid arthritis patients in Korea.

This study measured the prevalence of use of complementary and alternative medicine (CAM) in Korean patients with rheumatoid arthritis (RA). A trained nurse conducted 20-min questionnaire-based interviews at the hospitals when each patient visited as an outpatient. The questionnaire included questions on demographic information, clinical information, and the use of CAM. Of the 153 respondents, 125 (82%) had used CAM; 37% of those who used CAM had started taking CAM products following suggestions from family members and other relatives. In users of CAM, 35% considered that it improved the symptoms of RA, and 14% felt it was effective in achieving psychological relaxation. We categorized treatment into six CAM categories used by the respondents: 84.0% of patients used traditional Oriental medical treatments, 70.4% used plant- and animal-derived over-the-counter health care products, and 13.6% used manual therapies. Most RA patients (64%) would like to try a new type of CAM. About half of the respondents (48%) expected to receive information about CAM from their general practitioner even if most (72%) did not discuss their use of CAM with their doctor. Most of the RA patients in this study used CAM, and half reported beneficial effects. Despite the presence of adverse side effects, patients tended to use CAM without discussing it with their main physicians, suggesting that physicians should be actively involved in the prescription and use of CAM.

Patterns of three-phase bone scintigraphy according to the time course of complex regional pain syndrome type I after a stroke or traumatic brain injury.

We have proposed to evaluate different patterns represented on 3-phase bone scintigraphy (TPBS) according to the time course of complex regional pain syndrome (CRPS) type I (CRPS-I) after a stroke or traumatic brain injury. TPBS was performed in 50 consecutive patients for the evaluation of CRPS. We divided the patients into CRPS and non-CPRS groups based on the use of International Association for the Study of Pain criteria. We evaluated the changes on TPBS according to clinical stages based on time course. In the early acute stage within 6 weeks, minimal uptake on all TPBS phases was observed in the 90% of the patients in the CRPS-I group and in 75% of the patients in the non-CRPS group. In the acute stage of CRPS in the range of 2 to 20 weeks, moderately increased uptake was seen for 78%, 83%, and 83% of the patients in the CRPS group for the 3 phases, respectively. However, only 16% of the patients in the non-CRPS group had moderately increased uptake as seen on all TPBS phases. In the late stage of more than 21 weeks, there was no distinct difference in uptake between the 2 groups. A sequential change during the time course for the CPRS-I group was statistically significant (P < 0.05). Therefore, performance of follow-up TPBS may be useful to diagnose CPRS-I in uncertain cases of the early acute stage after a stroke or traumatic brain injury.

Assessment of cerebral hemodynamics to acetazolamide using brain perfusion SPECT in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary microangiopathy caused by mutations in the Notch3 gene located on chromosome 19, leading to 4 cardinal features with aura, cerebrovascular ischemic events, mood disturbances, and dementia. Acetazolamide (ACZ) has been promoted as a drug to determine cerebral hemodynamics, including cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in patients with cerebrovascular disease. In CADASIL patients with small-vessel disease, ACZ may be possible to increase CBF. We present that reduced CBF was dramatically improved after administration of ACZ on Tc-99m ECD brain perfusion SPECT in a CADASIL patient.

¹⁸F-FDG PET/CT imaging for mixed germ cell tumor in the pineal region.

Primary germ cell tumor (GCT) in the pineal region is very rare among all primary intracranial neoplasms. Here, we present the 18F-FDG PET/CT findings of a pineal mixed GCT in a 14-year-old boy. PET/CT showed little uptake of 18F-FDG in the mass in the pineal region, whereas MR imaging showed contra

Impact of symptoms of Work-related Musculoskeletal Disorders on health related Quality of Life in firefighter under the IT environment

This study was conducted to assess the impact of work-related musculoskeletal disorders (WMSDs) on health related quality of life (QoL) in the firefighter under the recent IT environment. The data were collected by face to face interview using a structured questionnaire in the 366 respondents. WMSDs symptoms were measured by a self-assessed questionnaire on symptom table of NIOSH and health-related QoL was measured by SF-36. The prevalence of WMSDs was 38.0% in upper limbs, 35.5% in the low back, 21.6% in lower limbs, and 59.3% in two or more parts of the body. Subjects with symptoms of WMSDs had significantly lower scores in 7 dimensions of QoL except `emotional role limitation` than those without symptoms of WMSDs at the area of upper extremities (neck, shoulder, arm/wrist, and hand/wrist/fingers). On the other hand, subjects with symptoms of WMSDs had significantly lower scores on all QoL dimensions than those without symptoms of WMSDs at the area of lower back or lower extremities. These results suggest that WMSDs had a negative effect on QoL. Therefore, prevention of WMSDs should be considered intervention strategies for improvement of QoL, especially in firefighters.

SPECT myocardial perfusion in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a rare hereditary small vessel disease. Although the symptoms are exclusively neurological, arteriopathy is generalized. We performed cardiac evaluation using myocardial perfusion single photon emission computed tomography (SPECT), dual-source 128-channel multidetector computed tomography (MDCT) angiogram, echocardiogram, and electrocardiogram (ECG) in a 46-year-old woman with CADASIL. No abnormal findings were observed on MDCT angiogram, echocardiogram, or ECG. However, SPECT demonstrated reversible perfusion defects in the left anterior descending artery territory. We suggest that myocardial perfusion SPECT is a valuable tool to identify risk from cardiovascular accident in CADASIL patients.
