Research paper thumbnail of Review Article: Non-Invasive Fetal Heart Rate Monitoring Techniques

A variety of techniques has been studied and is used on a daily basis in many hospitals. This review discusses and compares the operating principle, the key signal processing techniques, advantages and drawbacks of five of those techniques: fetal electrocardiography (FECG) using abdominal surface electrodes, photoplethysmography (PPG) using near infrared (NIR) light, Doppler ultrasound, ultrasound based cardiotocography (CTG) known as electronic fetal monitoring and fetal magnetocardiography (FMCG). The review leads to the conclusion that the PPG overcomes almost all of the drawbacks of the other methods and thus deserves the most attention in future biomedical research.

Research paper thumbnail of Cataract Surgery Planning in Amblyopic Patients – Which eye first? Awareness of the Potential for Post-operative Diplopia amongst Consultant Ophthalmic Surgeons in Wales

To compare prevailing views and preferences with recommendations in published literature.MethodA cross-sectional survey was conducted in which all consultant ophthalmologists working in Wales were invited to complete an online survey designed using the Survey Monkey tool (http://www.surveymonkey.com). The survey included a clinical scenario involving an amblyopic patient with bilateral cataracts with questions designed to elicit responders’ preferences with regard to which eye they would operate on first as well as the reasoning behind their clinical decision making.Results32 out of 42 consultants responded to the survey (a response rate of >75%). With regards to the chronological order of surgery 18 (56.26%) indicated that they would perform cataract surgery first on the non-amblyopic eye, 11 (34.4%) would surgically address the amblyopic eye first and three (9.4%) indicated that patient preference would dictate the choice regarding the laterality of the eye to be operated on first. While 24 responders (75.0%) had encountered amblyopic patients who had developed problems after cataract surgery only 10 (31.3%) opined that formal guidance from the Royal College of Ophthalmologists was warranted.ConclusionThese results indicate that awareness of post-cataract surgery diplopia, and in particular fixation switch diplopia, is not widespread amongst consultant ophthalmic surgeons in Wales.

In this retrospective study, a chart review was performed. Two groups with an equal number of patients who did or did not receive intracameral phenylephrine during phacoemulsification were compared for differences in outcomes, risk factors and complications. The Chi-square test was used for comparison between groups. P<0.05 was statistically significant. The two groups were well matched with regard to preoperative ophthalmic and systemic risk factors for complications and had very similar phacoemulsification power and time profiles. No differences in outcome were detected (P>0.05, all comparisons). This retrospective study suggests that intracameral phenylephrine normalizes the intraoperative risk of small pupil cataract surgery and is not associated with an increased risk of systemic or postoperative ophthalmic complications.
