Office Based Endovenous Radiofrequency Ablation of Truncal Veins: A Case for Moving Varicose Vein Treatment out of Operating Theatres.

Objectives: This study aims to assess the efficacy and outcomes at one year after office based endovenous radiofrequency ablation (OBEVRFA) as a standalone procedure for varicose veins under local anaesthesia.

Methods: A retrospective study of prospectively collected data of all OBEVRFAs done in the vascular unit from April 2014 to June 2016 was performed. The demographics, clinical findings, initial venous duplex ultrasound (DUS) findings, the vein ablated, and immediate complications were recorded.

Application of mid-infrared chemical imaging and multivariate chemometrics analyses to characterise a population of microalgae cells.

A suite of multivariate chemometrics methods was applied to a mid-infrared imaging dataset of a eustigmatophyte, marine Nannochloropsis sp. microalgae strain. This includes the improved leader-follower cluster analysis (iLFCA) to interrogate spectra in an unsupervised fashion, a resonant Mie optical scatter correction algorithm (RMieS-EMSC) that improves data linearity, the band-target entropy minimization (BTEM) self-modeling curve resolution for recovering component spectra, and a multi-linear regression (MLR) for estimating relative concentrations and plotting chemical maps of component spectra.

Heterogeneous catalytic transesterification of phosphatidylcholine.

The transesterification of phosphatidylcholine (PC) via homogeneous and heterogeneous catalysis was investigated for the production of fatty acid methyl esters (FAME) i.e. biodiesel.

Perforated sigmoid diverticulum mimicking acute appendicitis in a young patient: a case report.

Acute colonic diverticula are uncommon in patients <40 years of age, with an incidence between 2% and 10%. In such patients, the condition may be misdiagnosed in the acute setting, because it is often not considered and may be mistaken for acute appendicitis, particularly if there are predominantly right-sided signs. As a result, it may result in diagnostic delay and complications.

A rare and unusual case of bilateral, axillary, metachronous apocrine carcinoma.

Apocrine carcinoma is a rare sweat gland neoplasm with very few cases reported in the published literature. We report a case of primary axillary apocrine carcinoma with later recurrences in both axillae. A 55-year-old man was clinically diagnosed with hydradenitis suppurativa in the right axilla, and after excision of lesion, histology showed metastatic adenocarcinoma of probable breast origin.
