Fulltext Bone mineral densities and hip axis lengths of normal Singapore women

Ng CED, Sundram F, Mahbub UR, Hoon P

Med J Malaysia, 1999 Jun;54(2):180-4.
PMID: 10972027

This study aims to evaluate the bone mineral densities and hip axis lengths of women in the local population. 227 normal Singapore women of ages 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). The trend of BMDs at the left femoral neck and the lumbar spine remains fairly constant with increasing age until the 45-49 years age-band, beyond which there is a consistent decline. The mean hip axis length is 10.3 cm with a standard deviation of 0.6 cm. In general, the bone mineral densities in the femoral neck and lumbar spine as measured by DXA and the hip axis length of the local population is lower than corresponding figures reported in the Western population.

Fracture risk prediction in post-menopausal women with osteopenia and osteoporosis: preliminary findings

Nik Mohd Hatta NNK, Lokman M, Said N M, Daud A, Ibrahim M, Sharifudin MA, et al.

Enferm Clin, 2018 Feb;28 Suppl 1:232-235.
PMID: 29650194 DOI: 10.1016/S1130-8621(18)30074-3

OBJECTIVE: The study aims to identify the risk of obtaining a fracture among post-menopausal women with osteopenia and osteoporosis.

METHOD: This work was a cross-sectional study involving a purposive sample of 87 post-menopausal women who attended the orthopedic and menopause clinics of Hospital Tengku Ampuan Afzan, Kuantan. The data were entered into the WHO fracture risk assessment tool (FRAX®) to predict major fracture and risk for hip fracture in 10 years' time.

RESULTS: The mean age of the respondents was 61.6 years (SD=7.9). Among the respondents, 50.6% had osteopenia and nearly half (48.3%) had osteoporosis. The mean number of menopausal years of the respondents was 11.9 (SD=8.5), ranging between 1 and 44 years. The FRAX findings indicated 9.7% major osteoporotic fracture probability and 3.5% hip fracture probability, which were denoted as high risk. A Pearson correlation coefficient was computed to assess the relationship between menopausal years and the FRAX major osteoporotic fracture probability. A significant positive correlation was found between the two, but the correlation was weak (r=0.581, n=87, p < 0.001).

CONCLUSIONS: The present findings indicate that menopausal years have a positive correlation with the risk of obtaining a fracture.

Study site: orthopedic and menopause clinics of Hospital Tengku Ampuan Afzan, Kuantan.

Fulltext The association between various visual function tests and low fragility hip fractures among the elderly: a Malaysian experience

Chew FL, Yong CK, Mas Ayu S, Tajunisah I

Age Ageing, 2010 Mar;39(2):239-45.
PMID: 20065356 DOI: 10.1093/ageing/afp259

BACKGROUND: hip fractures are an increasing source of morbidity and mortality in older people. The role of visual function tests such as visual impairment, stereopsis, contrast sensitivity and visual field defects in low fragility hip fractures in Asian populations is not well understood.
OBJECTIVE: to determine the association between various visual function tests and low fragility hip fractures in an Asian population.
DESIGN: case-control study.
SETTING: University Malaya Medical Centre, Kuala Lumpur, Malaysia.
SUBJECTS: 108 cases aged > or = 55 years admitted with low fragility fractures and 108 controls (matched for age, gender and race).
METHODS: both cases and controls underwent a detailed ophthalmological examination, which included visual acuity, stereopsis, contrast sensitivity and visual field testing.
RESULTS: poorer visual acuity (odds ratio, OR = 4.08; 95% confidence interval, CI: 1.44, 11.51), stereopsis (OR = 3.60, 95% CI: 1.55, 8.38), contrast sensitivity (OR = 3.34, 95% CI: 1.48, 7.57) and visual field defects (OR = 11.60, 95% CI: 5.21, 25.81) increased the risk of fracture. Increased falls were associated with poorer visual acuity (OR = 2.30, 95% CI: 1.04, 5.13), stereopsis (OR = 2.11, 95% CI: 1.03, 4.32), contrast sensitivity (OR = 2.12, 95% CI: 1.05, 4.30) and visual field defects (OR = 3.40, 95% CI: 1.69, 6.86).
CONCLUSION: impaired visual acuity, stereopsis, contrast sensitivity and visual field defects are associated with an increased risk of low fragility hip fractures. We recommend that all patients aged > or = 55 should have an annual ophthalmological examination that includes visual acuity, contrast sensitivity, stereopsis and visual field testing to assess the risks for falls and low fragility fractures.

A case report of primary hyperparathyroidism with severe bony involvement and nephrolithiasis

Chan SP, Hew FL, Jayaram G, Kumar G, Chang KW, Tay A

Ann Acad Med Singap, 2001 Jan;30(1):66-70.
PMID: 11242630

INTRODUCTION: Although the majority of patients with primary hyperparathyroidism have a relatively asymptomatic benign disorder, there are patients who have a more aggressive disorder.
CLINICAL PICTURE: We report a case of primary hyperparathyroidism presenting during pregnancy complicated by antepartum haemorrhage and severe prematurity. The diagnosis was made postpartum, when her problems rapidly progressed to result in severe neuromuscular weakness, bilateral pathological hip fractures as well as nephrolithiasis.
TREATMENT: Surgical parathyroidectomy was performed. The underlying lesion was a large solitary parathyroid adenoma with cystic elements.
CONCLUSION: Primary hyperparathyroidism is not an innocuous disease and can result in severe morbidity if left untreated.

Cost-effectiveness of bisphosphonates for prevention of fracture related to glucocorticoid-induced osteoporosis in Malaysia

Mohd-Tahir NA, Thomas P, Mohamed-Said MS, Makmor-Bakry M, Li SC

Int J Rheum Dis, 2018 Mar;21(3):647-655.
PMID: 29105349 DOI: 10.1111/1756-185X.13206

INTRODUCTION: Glucocorticoid therapy is associated with an appreciable risk of bone loss leading to fractures that require expensive treatments. This study aimed to evaluate the cost-effectiveness of bisphosphonates for prevention of hip fracture in glucocorticoid-induced osteoporosis (GIOP) in Malaysia.

METHOD: Retrospective data were collected from GIOP patients referred to the Universiti Kebangsaan Malaysia Medical Centre. Fracture events and direct medical costs were compared between bisphosphonates and calcium/vitamin D combination.

RESULTS: Fracture events were reported in 28 out of 93 included patients, with hip and vertebral fractures representing 42.9% and 35.7%, respectively. Overall, the use of bisphosphonates could not be considered cost-effective for treatment of all GIOP patients. The presence of certain fracture risk factors was able to modify the cost-effectiveness of bisphosphonates. Bisphosphonates was considered cost-effective if started in patients more than 60 years old. However, the use of bisphosphonates was not cost-effective in GIOP patients with secondary osteoporosis. The incremental cost-effectiveness ratios (ICER) of bisphosphonates in patients with risk factors of previous fracture or rheumatoid arthritis were Malaysian Ringgits (MYR) 108 603.40 and MYR 25 699.21, respectively.

CONCLUSION: Fracture risk factors of age, previous fracture, rheumatoid arthritis and secondary osteoporosis may modify the cost-effectiveness outcomes of bisphosphonates. Bisphosphonates would be considered cost-effective in patients more than 60 years old as compared to calcium/vitamin D treatments. Further evaluation of the impact of fracture risk factors in larger populations would provide more precise information to better assist rational and economical use of anti-osteoporosis treatment in GIOP patients.
