Introduction: Calcium supplementation and pharmacotherapy are recommended in the preventive management of osteoporosis. Many previous studies report of underdiagnosis and undertreatment of osteoporosis among elderly patients with hip fractures. We undertook this study to determine the dietary calcium levels in our local elderly population who were admitted with hip fractures., Methods: 77 patients, between the ages of 60 and 98 years of age, and admitted to our department between January 2001 and September 2001 for hip fractures, were studied. The dietary calcium intakes of these patients were determined by a food frequency questionnaire and a detailed diet history. Bone mineral density (BMD) studies were performed on 55 of these patients to confirm the diagnosis of osteoporosis., Results: The mean daily calcium intake was found to be 650 mg. Only six of our hip fracture patients (7.8 percent) had a daily calcium intake above the recommended levels of 1,000 mg per day. For the 55 patients who had BMD performed, only one patient had a BMD within the normal range. 34 patients (64.2 percent) had hip T-scores in the osteoporotic range and 18 patients (33.9 percent) had hip T-scores in the osteopenic range. We found that the patients with BMD in the osteoporotic and osteopenic ranges had no significant difference in the dietary calcium intake., Conclusion: The dietary calcium intake of our elderly patients with hip fractures is insufficient. They would benefit from dietary education and calcium supplements to prevent deterioration in bone density and subsequent osteoporotic fractures.

Introduction: The presence of axillary lymph node metastases is an important prognostic factor in breast cancer. Sentinel lymph node biopsy (SLNB) is an emerging method for the staging of the axilla. It is hoped that with SLNB, the morbidity from axillary lymph node dissection (ALND) can be avoided without compromising the staging and management of early breast cancer. However, only patients found to be SLNB negative benefit from this procedure, as those with positive SLNB may still require ALND. Our objective is to study the various clinico-pathological factors to find predictive factors for axillary lymph node involvement in early breast cancer. It is hoped that with these factors, we will be better able to identify groups of patients most likely to benefit from SLNB., Methods: A retrospective study of 380 early breast cancer cases (stage T1 and T2, N0, N1, M0) in women treated in the Department of General Surgery, Tan Tock Seng Hospital, between January 1999 and August 2002, was conducted. Incidence of nodal metastases was correlated with clinico-pathological factors, and analysed by univariate and multivariate analyses., Results: Approximately 35 percent of the 380 cases of early breast cancer had nodal metastases. Multivariate analyses revealed four independent predictors of node positivity: tumour size (p-value equals 0.0001), presence of lymphovascular invasion (p-value is less than 0.0001), tumours with histology other than invasive ductal or lobular carcinoma (p-value equals 0.04), and presence of progesterone receptors (p-value equals 0.05)., Conclusion: We have found independent preoperative predictive factors in our local population for the presence of nodal metastases. This information can aid patient selection for SLNB and improve patient counselling.

Aggressive fibromatosis is a locally infiltrative fibroblastic tumour that arises from fascial planes of soft tissue but does not metastasize. It is known to invade muscle, subcutaneous tissue and neurovascular structures. However, bone involvement is very rare and there has been few reports of bone involvement. We present a case of a young man with aggressive fibromatosis of the right lower leg with fibula involvement.

Kandang Kerbau Hospital saw 165 new cases of uterine cancers over the 4-year period from 1991 to 1994. The median age of presentation was 54.1 years and 10.9% of these cases occurred in those aged less than 40 years, unlike the corresponding figures of 61 years and less than 5%, respectively, which are often quoted for endometrial cancers in standard textbooks. Endometrioid adenocarcinoma was the commonest type of uterine cancer seen in our population (75.2%) as in other series. However, we had fewer cases of adenoacanthoma (1.4%) and adenosquamous carcinoma (1.4%) but more cases of uterine sarcoma (11.5%) than is usually reported. 6.7% of our patients had papillary serous adenocarcinoma and 3.0% had clear cell carcinoma. These 2 sub-types are associated with poorer prognosis and there is a need to increase awareness of their existence in our local population as their management differs from that for the usual endometrioid adenocarcinoma. We had fewer patients with stage I disease (53.3%) but more patients with stage III disease (22.4%). This is most likely due to the use of surgico-pathological staging currently as opposed to the clinical staging used previously which led to the under-staging of a proportion of patients.

Currently, women with gestational diabetes mellitus have a repeat oral glucose tolerance test 6 weeks after delivery to identify those with persistent glucose intolerance. In this study, 298 women with gestational diabetes had a postnatal oral glucose tolerance test and of these, 23.2% had persistent glucose intolerance after delivery. The aim of this study was to determine if the antenatal oral glucose tolerance test results could be used to predict which patients would have persistent glucose intolerance after delivery. If only those with severely abnormal antenatal results had persistent disease, then those with only mildly abnormal antenatal results could be spared the postnatal oral glucose tolerance test. Using receiver operator characteristic curves, this study showed that the antenatal oral glucose tolerance test results could not be used to predict reliably which patients would continue to have abnormal glucose tolerance postnatally. Hence, postnatal oral glucose tolerance testing of all patients with gestational diabetes is still necessary as the detection of persistent glucose intolerance is important for the control of the diabetic condition so as to minimise long-term complications.
