Purpose: Port removal is usually a straightforward procedure delegated to trainees. However, some port removals are complicated by central venous catheter (CVC) fragmentation, a challenge for even experienced surgeons. This study aimed to determine the incidence of, and risk factors for, complicated port removal in children.
Methods: A single-centre study assessed the outcome of removal for all paediatric ports inserted from 1996 to 2012. Data were recorded detailing patient, insertion, device and removal characteristics. Risk factors for complicated removals were scrutinised using Chi-square tests; p < 0.05 significant.
Results: Of 628 ports inserted from 1996 to 2012, 443 were subsequently removed at the same centre. 8/443 (1.8%) removals were complicated by CVC fragmentation, a median of 3.3 (2.4-3.9) years after insertion. Of complicated cases, 8/8 underwent formal neck dissection, 3/8 intravascular dissection, and 1/8 endovascular retrieval. 2/8 cases have retained intravascular CVC fragments. Risk factors for complication were CVC caliber <6Fr (p < 0.001) and use duration >2 years (p < 0.001).
Conclusion: Greatest care and senior supervision should be ensured when removing ports with CVC caliber <6Fr and/or >2 years since insertion. However, complications also occur with larger CVCs or after shorter durations. Therefore, the key to avoiding complicated port removal may simply be: preparation, preparation, neck preparation.

Chyle leak is a rare complication following nephrectomy and may result in chylous ascites. A patient in her 70s was diagnosed with a left renal tumour and underwent a robotic-assisted radical nephrectomy. She presented 9 days post discharge with chyle leaking from the left port site wound, which settled after 2 days of inpatient monitoring.

Vascular malformations (VMs) are dysplastic abnormalities of vascular channels, differing from vascular tumors by their slow growth. Arteriovenous malformations (AVMs) arise between weeks 4-10 of intrauterine life, with a prevalence of 1 in 100,000 among Caucasians. Common in the head, neck, and hands, AVMs may be asymptomatic or cause symptoms like pain, deformity, and disability.

An increasing amount of water pollution is being caused by an increase in industrial activity. Recently, a wide range of methods, including extraction, chemical coagulation, membrane separation, chemical precipitation, adsorption, and ion exchange, have been used to remove heavy metals from aqueous solutions. The adsorption technique is believed to be the most highly effective method for eliminating heavy metals from wastewater among all of them.

Bioelectrochemical systems (BES) as environmental remediation biotechnologies have boomed in the last two decades. Although BESs combined technologies with electro-chemistry, -biology, and -physics, microorganisms and biofilms remain at their core. In this review, various functional microorganisms in BESs for CO reduction, dehalogenation, nitrate, phosphate, and sulfate reduction, metal removal, and volatile organic compound oxidation are summarized and compared in detail.

A novel strategy for cytochrome c selective recognition assisted with cucurbit[6]uril by host-guest interaction via N-terminal epitope imprinting and reversible addition-fragmentation chain transfer (RAFT) polymerization was developed. N-terminal nonapeptide of cytochrome c (GI-9) was used as the epitope template to achieve highly selective recognition of cytochrome c. As a common supramolecule in recent years, cucurbit[6]uril can encapsulate the butyrammonium group of lysine residue to capture the peptide and improve the corresponding spatial orientation by the host-guest interaction for GI-9 or cytochrome c recognition.
