Article Synopsis
  • Breast implant augmentation is generally a low-risk procedure, with rare severe complications, mainly involving rupture or leakage of the implants.
  • Anaplastic large cell lymphoma (ALCL) is the most recognized cancer linked to breast implants, but other types, like carcinomas and extremely rare BIA sarcomas, have also been documented.
  • The authors describe a specific case of a rare undifferentiated pleomorphic sarcoma (UPS) that was initially misdiagnosed as ALCL, emphasizing the need to consider this diagnosis in unclear cases related to breast implants.

Article Synopsis
  • Pyruvate kinase (PK) is a crucial enzyme in glycolysis that influences muscle quality, and its characteristics can be affected by phosphorylation levels.
  • The study examined how adding l-histidine (l-his) at a concentration of 0.06% affects PK phosphorylation and activity in conditions of 1% NaCl during the early postmortem phase.
  • Results showed that l-his led to dephosphorylation of PK, increased its activity, altered its secondary structure, and suggested that adding l-his under low NaCl could enhance meat quality postmortem.

Background: Patients with early breast cancer undergoing primary surgery, who have low axillary nodal burden, can safely forego axillary node clearance (ANC). However, routine use of axillary ultrasound (AUS) leads to 43% of patients in this group having ANC unnecessarily, following a positive AUS. The intersection of machine learning with medicine can provide innovative ways to understand specific risks within large patient data sets, but this has not yet been trialed in the arena of axillary node management in breast cancer.

Purpose: Axillary staging is an important prognostic factor in breast cancer. Sentinel lymph node biopsy (SNB) is currently used to stage patients who are clinically and radiologically node-negative. Since the establishment that axillary node clearance (ANC) does not improve overall survival in breast-conserving surgery for patients with low-risk biological cancers, axillary management has become increasingly conservative.

Background: A procedure for sentinel lymph node biopsy (SLNB) using superparamagnetic iron-oxide (SPIO) nanoparticles and intraoperative sentinel lymph node (SLN) detection was developed to overcome drawbacks associated with the current standard-of-care SLNB. However, residual SPIO nanoparticles can result in void artefacts at follow-up magnetic resonance imaging (MRI) scans. We present a grading protocol to quantitatively assess the severity of these artefacts and offer an option to minimise the impact of SPIO nanoparticles on diagnostic imaging.

Introduction: The use of neo-adjuvant radiotherapy (NRT) has been proven effective at improving cancer related outcome measures, including overall-survival (OS) in the management of solid cancers. However, its utilisation in breast cancer has not been explored to the extent of neo-adjuvant chemotherapy (NAC). The evidence for the application of NRT in breast cancer is evaluated.

It is recognised that surgical conservatism is the most effective way of managing the axilla in breast cancer patients undergoing primary breast conserving surgery. The extended clinical scenarios in which a less aggressive approach can be safely adopted warrant consideration-including a group of patients who potentially could bypass surgical staging of the axilla altogether. The application of omission of further surgical management and axillary radiotherapy in the primary surgical and neoadjuvant chemotherapy settings are considered.

Nitrification inhibitors (NIs) are used to retard the nitrification process and reduce nitrogen (N) losses. However, the effects of soil properties on NI efficacy are less clear. Moreover, the direct and indirect effects of soil property variations on NI efficiency in minimizing carbon dioxide (CO) emissions have not been previously studied.

The residual effect of tobacco biochar (TB ≥ 500°C) mono and co-application with Ca-hydroxide (CH), Ca-bentonite (CB) and natural zeolite (NZ) on the bio-availability of trace elements TE(s) in alkaline soils has not been deeply studied yet. A pot study that had earlier been investigated TB mono and blended with CH, CB and NZ on the immobilization of Pb, Cu Cd, and Zn by Chinese cabbage. Maize crop in the rotation was selected as test plant to assess the residual impact of amendments on stabilization of Pb, Cu Cd, and Zn in mine polluted (M-P), smelter heavily and low polluted (S-HP and S-LP, respectively) soils.

Breast cancer is a heterogenous disease, exhibiting a wide range of morphological phenotypes shaping its prognosis and clinical course. However, optimal management of rarer breast cancer subtypes is often undefined and controversial in literature due to the lack of large studies and randomised trials. This review aims to discuss the treatment of 13 rare epithelial subtypes, focussing on surgery and adjuvant therapies.

Management guidelines for male breast cancer have long been extrapolated from those for female breast cancer, which are based on large, randomised-controlled trials. While there are no randomised-controlled trials for male breast cancer management mainly due to the rarity of the disease, the only type of evidence available comes from retrospective studies, subject to selection biases and small sample sizes. Male breast cancer, while similar to female breast cancer in many respects, has some important differences that can affect management choices.

The configuration of autologous free-flap breast reconstruction services within regional hubs means that increasing numbers of patients operated upon at these units will be external referrals without their oncological investigations carried out at the tertiary receiving centre. Oncoplastic guidelines exist that clearly state the minimum necessary patient information that should be provided by the referring unit to the reconstruction centre. However, the logistics of such critical information transfer can be challenging, but it is essential that such issues are addressed to ensure safe oncological management of patients undergoing autologous breast reconstruction.

Purpose: The steady move towards axillary conservatism in breast cancer is based on studies demonstrating that axillary node clearance affords no survival benefit in a subset of patients with a positive pre-operative axillary ultrasound (AUS). However, less attention has been paid to AUS-negative patients who receive sentinel node biopsy as standard.

Methods: Previously assembled systematic review data was reassessed to evaluate nodal burden amongst patients with breast cancer and a clinically and radiologically negative axilla.

Background: Sentinel node biopsy using radioisotope and blue dye remains a gold standard for axillary staging in breast cancer patients with low axillary burden. However, limitations in the use of radioisotopes have resulted in emergence of novel techniques. This is the first in vivo study to assess the feasibility of combining the two most common novel techniques of using a magnetic tracer and indocyanine green (ICG) fluorescence.

Background: Management of the axilla in breast cancer is becoming increasingly conservative. Patients identified with a low axillary nodal burden (two or fewer involved nodes) at sentinel node biopsy (SNB) can avoid completion axillary node clearance (cANC). 'Fast track' to ANC in patients with involved nodes on pre-operative ultrasound may be over-treating a subgroup of these patients with low nodal burden, which would have precluded their need for ANC.

Purpose: Breast-conserving surgery is effective for breast cancer treatment but is associated with morbidity in particular high re-excision rates. We performed a systematic review and meta-analysis to assess the current evidence for clinical outcomes with minimally invasive ablative techniques in the non-surgical treatment of breast cancer.

Methods: A systematic search of the literature was performed using PubMed and Medline library databases to identify all studies published between 1994 and May 2016.

Introduction: Breast fibroadenomata (FAD) are benign lesions which occur in about 10 % of all women. Diagnosis is made by triple assessment (physical examination, imaging and/or histopathology/cytology). For a definitive diagnosis of FAD, the treatment is conservative unless the patient is symptomatic.

Unlabelled: The magnetic technique for sentinel node biopsy provides a radioisotope-free alternative for staging breast cancer. It requires refinement to reduce "residual iron content" at injection sites by maximising lymphatic uptake to prevent "void artefacts" on magnetic resonance imaging (MRI), which could adversely affect clinical use. The site and timing of injection of magnetic tracer was evaluated in a murine tumour model (right hind limb) in 24 wild type mice.
