It is considered the “gold standard” by the World Health Organisation (WHO) and is the most accurate and inexpensive test to diagnose osteoporosis.…

Omega-3 supplements in pregnancy for leaner kids?

11th May 2024, A/Prof Chee L Khoo

Omega-3 supplements?

I recall reading somewhere that increasing fish intake during pregnancy results in leaner offsprings. It all makes sense as we know that ω-3 fatty acid (ω-3 FA) is beneficial for adults (also read somewhere). It must be good for babies then. Is there data on those claims? Well, sort of. We shall look into them.…

Uterine artery doppler – when would you order one?

13th February 2024, NIA Diagnostic Imaging

Uterine Artery

Commonly, uterine artery doppler ultrasound is conducted to measure the blood flow in the uterine arteries. This specific ultrasound allows for qualitative information to be gathered on the presence/absence of flow, the direction of flow, the quality of flow, to determine if the flow is laminar or turbulent and to distinguish waveform shape (low resistance, high resistance, early diastolic notch) (Naguib et al.,2012).…

Salpingectomy to prevent ovarian cancer?

27th January 2024, A/Prof Chee L Khoo


The World Health Organisation classifies epithelial ovarian carcinomas into several morphological categories according to cell type: serous carcinomas (SC), mucinous carcinomas, endometrioid carcinomas, and clear-cell carcinomas, transitional-cell Brenner tumours, mixed, and undifferentiated type [1]. SC account for 75-80% of epithelial carcinomas and are subdivided into high-grade SC (HGSC) and low-grade SC (LGSC). Like any other cancers, early diagnosis would be important to improve the prognosis but often when diagnosed, ovarian cancer is in its advanced stages.…

Cervical screening – hands up who’s not here?

25th November 2023, A/Prof Chee L Khoo

Cervical screening for cervical cancer for the prevention of cervical cancer has to be one of the most successful campaigns in primary care. For most, instead of having an intimate check every two years, doing it every 5 years is such a relief. For others, it is still having to endure an insertion of a vaginal speculum.…

Pelvic organ prolapse – diagnosis with translabial ultrasound

11th June 2023, NIA Diagnostic Imaging

translabial US

The incidence of pelvic organ prolapse is highly associated with increased age and vaginal childbirth (Weintraub et al., 2020). Majority of patients who present with POP may not report any symptoms. Patients who do present with symptoms, however, often describe a sense of feeling of a bulge protruding through the vaginal opening. In younger women, vaginal laxity is more commonly noticed and related to sexual dysfunction (Peter Dietz, 2015).…
