Autologous breast reconstruction in older women: A retrospective single-centre analysis of complications and uptake of secondary reconstructive procedures.

BACKGROUND: Women aged ≥65 years have the highest age-specific rates of breast cancer incidence in the UK. However, national audit results demonstrate that the rates of post-mastectomy breast reconstruction offered to and performed on this age group are considerably lower than in younger women (Jeevan, 2009). This discrepancy may arise from unsubstantiated concerns over greater medical and surgical risk in older patients (James, 2015). In the present study, the first of its kind in the UK, we sought to evaluate potential differences in postoperative complications following autologous breast reconstruction between young and older patient populations. METHODS: We conducted a retrospective review of 59 patients (31 'younger' <65 years; 28 'older' ≥65 years) who underwent autologous breast reconstruction at Oxford University Hospitals, between 2008 and 2017. Clinical, operative, and outcome variables were compared across the two age groups. To examine the complete multi-stage process of breast reconstruction as a whole, we also compared rates of uptake of multiple secondary reconstructive and revisional procedures across age groups. KEY RESULTS: Major surgical, minor surgical, and medical complication rates, as well as length of stay, did not differ significantly by age group. The scar revision rate (at the flap donor site) was higher in the <65 group (19.4% vs. 0.0%; p = 0.025). Otherwise, rates of secondary reconstructive and revisional procedures were comparable across both groups. CONCLUSION: Patients aged ≥65 years were not at a significantly greater risk of complications following autologous breast reconstruction compared to younger patients. Chronological age, in itself, should not influence treatment decisions surrounding breast reconstruction.

Comparison between confocal scanning laser tomography, scanning laser polarimetry and optical coherence tomography on the ability to detect localised retinal nerve fibre layer defects in glaucoma patients.

BACKGROUND/AIM: To compare the ability of confocal scanning laser tomography (CSLT), scanning laser polarimetry (SLP) and optical coherence tomography (OCT) in recognising localised retinal nerve fibre layer (RNFL) defects. METHODS: 51 eyes from 43 patients with glaucoma were identified by two observers as having RNFL defects visible on optic disc photographs. 51 eyes of 32 normal subjects were used as controls. Three masked observers evaluated CSLT, SLP and OCT images to determine subjectively the presence of localised RNFL defects. RESULTS: Interobserver agreement was highest with OCT, followed by SLP and CSLT (mean kappa: 0.83, 0.69 and 0.64, respectively). RNFL defects were identified in 58.8% of CSLT, 66.7% of SLP and 54.9% of OCT (p = 0.02 between SLP and OCT) by at least two observers. In the controls, 94.1% of CSLT, 84.3% of SLP and 94.1% of OCT scans, respectively, were rated as normal (p = 0.02 between CSLT and SLP, and SLP and OCT). CONCLUSION: Approximately 20-40% of localised RNFL defects identified by colour optic disc photographs are not detected by CSLT, SPL or OCT. SLP showed a higher number of false-positive results than the other techniques, but also had a higher proportion of correctly identified RNFL defects in the glaucoma population.

Degree of angle closure and extent of peripheral anterior synechiae: an anterior segment OCT study.

AIMS: To evaluate the relationship between angle width as determined by anterior segment optical coherence tomography (AS-OCT) and the presence of peripheral anterior synechiae (PAS). METHODS: This was a prospective observational case series in which 203 subjects with primary angle closure or open angles were recruited. Images of the nasal, temporal and inferior angles were obtained with AS-OCT in dark conditions. Subjects then underwent gonioscopy by an independent examiner who was masked to the AS-OCT findings. PAS were identified by gonioscopy and defined as abnormal adhesions of the iris to the angle that were at least half a clock hour in width and present to the level of the anterior trabecular meshwork or higher. The total clock hours of PAS were recorded. RESULTS: Sixty-eight subjects (33.5%) were PACS, 76 subjects (37.4%) had PAC/PACG, 14 (6.9%) had primary open angle glaucoma, and 45 (22.2%) subjects were normal with open angles. There was a weak but significant correlation between the angle opening distance (AOD), trabecular iris space area (TISA) and angle recess area (ARA) with clock hours of PAS (Spearman's correlation coefficients = -0.30, -0.32 and -0.32, respectively, p<0.001). The mean values of the AOD, TISA and ARA in the nasal, temporal and inferior quadrants were significantly less in eyes with PAS compared with those without (p<0.001, Mann-Whitney U test). Analysis by quadrant showed that these parameters were smaller in the nasal and temporal quadrants in eyes with PAS (p<0.01). CONCLUSIONS: Angle width determined by AS-OCT and the extent of PAS were weakly correlated, and angle width was significantly smaller in eyes with PAS.

A randomized double-masked crossover study comparing latanoprost 0.005% with unoprostone 0.12% in patients with primary open-angle glaucoma and ocular hypertension.

PURPOSE: To compare the intraocular pressure)-lowering effect and side effects of latanoprost 0.005% once daily with unoprostone 0.12% twice daily. METHODS: Sixty patients with primary open-angle glaucoma or ocular hypertension were randomized to receive either latanoprost once daily in the evening and placebo once daily in the morning, or unoprostone twice daily in the morning and evening. The study was double masked and followed a crossover design with two treatment periods of 1 month separated by a 3-week washout period. The intraocular pressure was measured at 9 AM and 5 PM on the baseline and day 28 visits, and at 9 AM on day 2 and day 14 visits of each treatment period. The 9 AM measurement was taken 2 hours and 13 hours after the last drop of unoprostone and latanoprost, and the 5 PM measurement was at 10 and 21 hours, respectively. The mean of the measurements was calculated. Safety parameters were also recorded. RESULTS: Fifty-six patients completed both treatment periods and had intraocular pressure data available for evaluation. After 1 month of treatment, latanoprost significantly reduced intraocular pressure (mean +/- SEM) by 6.1 +/- 0.5 mm Hg (P <.001) and unoprostone by 4.2 +/- 0.4 mm Hg (P <.001) adjusted from an overall baseline of 22.3 +/- 0.5 mm Hg and 23.2 +/- 0.4 mm Hg, respectively. The difference of 1.9 mm Hg between treatments was statistically significant in favor of latanoprost [P =.003, analysis of covariance (ANCOVA)]. Unadjusted analysis of responders using the percentage decrease in intraocular pressure showed that the proportion of responders in the latanoprost-treated group was greater than in the unoprostone-treated group. Adverse ocular symptoms and findings were mild in both treatment groups. Eye redness and ocular irritation were the most frequently reported events. CONCLUSIONS: Latanoprost once daily was significantly more effective in reducing intraocular pressure compared with unoprostone twice daily after 1 month of treatment in patients with primary open-angle glaucoma and ocular hypertension. Both drugs were well tolerated with few ocular adverse events.

Trends in the pattern of blindness and major ocular diseases in Singapore and Asia.

This article details the changing trends in the major causes of blindness and visual impairment in Singapore over the past four decades. A comprehensive review of existing data from published and unpublished sources on ocular disease studies and surveys in Singapore was conducted. The rates of blindness and visual impairment from cataract, age-related macular degeneration, glaucoma, diabetic retinopathy and refractive errors, as well as other major diseases are described and compared with other Asian countries. Such epidemiological data on the blinding conditions in our population are vital in the understanding of trends in ocular diseases, as well as in prioritizing current health services and preventive programmes.
