Reversible posterior leukoencephalopathy is commonly associated with malignant hypertension, toxemia of pregnancy, or treatment with immunosuppressive drugs. A 17-year-old man who was diagnosed with traumatic rhabdomyolysis presented with seizure, visual disturbance, and severe pain in both thighs. Brain MRI revealed multiple areas of cortical and subcortical high signal intensities on T2 weighted images in the bilateral parieto-occipital lobes. He was treated with antihypertensive and anticonvulsant drugs and steroids. Forty days later, a follow-up MRI showed almost complete resolution of the brain lesions. The reversible posterior leukoencephalopathy may be associated with acute hypertension due to rhabdomyolysis-related acute renal failure. (J Korean Neurol Assoc 19(2):163~166, 2001)

Background: Age-adjusted bone mineral density (BMD) in postmenopausal women decreases in developed countries whereas incidence of osteoporotic fracture decreases or remains stable. We investigated secular trends of bone density from 2008 to 2017 among different age groups of postmenopausal women. Methods: We analyzed BMD data obtained from health check-ups of 4,905 postmenopausal women during three survey cycles from 2008 to 2017. We divided them into 3 groups by age (50–59 years, 60–69 years, and 70 years or more) and observed the transition of lumbar and femoral BMD in each group, before and after adjusting for variables that may affect BMD. Results: Age-adjusted BMD, bone mineral content (BMC), and T-score demonstrated a declining trend over the survey period at lumbar spine (−2.8%), femur neck (−3.5%) and total femur (−4.3%), respectively. In the analysis for the age groups, the BMD, BMC, and T-score presented linear declining trend (−6.1%) in younger postmenopausal women while women aged over 70 or more showed linear increasing trends (+6.3%) at lumbar spine during the survey period. Femoral neck and total femur BMD demonstrated a declining linear trend only in the 50–59 and 60–69 years groups (−5.5%, −5.2%, respectively), but not in the 70 years or more group. Conclusion BMD in younger postmenopausal women has decreased considerably but has increased or plateaued in elderly women. This discordance of BMD trends among different age groups may contribute to decreased incidence of osteoporotic fracture despite a recent declining BMD trend in postmenopausal women.

BACKGROUND: Elevated plasma total homocysteine is a risk factor for cardiovascular diseases. The authors investigated the parameters such as habit, body index, cardiovascular risk factors, nutrition relative to the plasma homocysteine concentration. METHODS: The subjects were 6,223 adults (3,377 males, 2,846 females) who were over 18 years of age and visited a health promotion center of a university hospital from March 2002 to January 2003. We assessed the relationship between the homocysteine level and the following parameters: sex, age, weight, body mass index, waist circumference, smoking, alcohol, systolic and diastolic blood pressure (BP), triglyceride, total cholesterol, high density lipoprotein cholesterol, creatinine, albumin and hemoglobin. RESULTS: The homocysteine levels was 10.5+/-5.9micromol/L in males, 7.3+/-2.6micromol/L in female. Thus it was significantly higher in males (P <0.001). After adjusting for variables that affect the homocysteine, the subjects over the age of 54 showed 10.7micromol/L (9.5, 12.0, 95% Confidence Interval), which was significantly (P=0.002) higher than the below the age of 38 groups 8.5micromol/L (7.8, 9.2, 95% CI). Non-smoking group showed 8.6micromol/L (8.4, 8.9, 95% CI), while over 28 pack-year group showed 9.6micromol/ L (9.2, 10.0, 95% CI), which was significantly (P <0.000) higher than the non-smoking groups. For the group with systolic BP over 132mmHg, it was 9.3micromol/L (8.8, 9.5, 95% CI). This was significantly (P=0.004) higher than 8.7micromol/L (8.4, 9.0, 95% CI) in the group whose systolic BP was less than 108 mmHg. The homocysteine was 10.4micromol/L (10.1, 11.7, 95% CI) for the group with creatinine over 1.0 mg/dL, which was significantly (P <0.000) higher than 7.9micromol/L (7.6, 8.2, 95% CI) in the group whose creatinine was less than 0.8 mg/dL. CONCLUSION: After adjusting for variables that affect the homocysteine, significant difference in its values was found between males and females. The homocysteine was significantly increased in the group whose age, systolic BP, amount of smoking, and creatinine were higher.
