Institutional Management of Abdominal Lymphatic Malformations: Evolution of Treatment Over a Decade.

INTRODUCTION: Abdominal lymphatic malformations (LM) have been historically managed with surgical resection; however, sclerotherapy and sirolimus have emerged as effective therapies. The purpose of our study is to evaluate our institutional change in management and outcomes for abdominal LM over the past decade. METHODS: A retrospective cohort study was performed for all children with an abdominal LM managed at our multidisciplinary Vascular Anomalies Center from 2011 to 2020. Patient demographics, symptoms, treatment, treatment response, and complications were analyzed with descriptive statistics. RESULTS: Twenty-nine patients with abdominal LM were identified with a median age at treatment of 6 y (interquartile range 3-14). A majority of lesions were identified as macrocystic (n = 18, 62%). The most common intervention was surgery alone (n = 14, 48%) followed by sirolimus alone (n = 4, 14%), and sclerotherapy + sirolimus (n = 4, 14%). Five patients were observed due to lack of symptoms at presentation. Prior to 2017, 91% (10/11) of LM were treated with surgery alone. Following 2017, only 31% (4/13) were treated with surgery alone. Sixty-seven percent (16/24) of treated patients had >95% reduction in LM maximum diameter. A majority of patients (23/24) who received treatment had improvement or resolution of symptoms at median 9-mo follow-up. Only three patients had post-treatment complications, including a drain site infection, small bowel obstruction, and an aspiration event. Complications only occurred after sclerotherapy sessions. CONCLUSIONS: Over the study period, our institution has transitioned to initial management of symptomatic abdominal LM with sclerotherapy and/or sirolimus with almost all treated patients having excellent or satisfactory treatment response. Post-treatment complications were rare.

The presentation, management and outcome of inflammatory breast cancer cases in the UK: Data from a multi-centre retrospective review.

OBJECTIVES: Inflammatory Breast cancer (IBC) is a rare but aggressive form of breast cancer. Its incidence and behaviour in the UK is poorly characterised. We collected retrospective data from hospitals in the UK and Ireland to describe the presentation, pathology, treatment and clinical course of IBC in the UK. MATERIALS AND METHODS: Patients with IBC diagnosed between 1997-2014 at fourteen UK and Irish hospitals were identified from local breast unit databases. Patient characteristics, tumour pathology and stage, and details of surgical, systemic and radiotherapy treatment and follow-up data were collected from electronic patient records and medical notes. RESULT: This retrospective review identified 445 patients with IBC accounting for 0.4-1.8% of invasive breast cancer cases. Median follow-up was 4.2 years. 53.2% of tumours were grade 3, 56.2% were oestrogen receptor positive, 31.3% were HER2 positive and 25.1% were triple negative. 20.7% of patients had distant metastases at presentation. Despite trimodality treatment in 86.4%, 40.1% of stage III patients developed distant metastases. Five-year overall survival (OS) was 61.0% for stage III and 21.4% for stage IV patients. CONCLUSIONS: This is the largest series of UK IBC patients reported to date. It indicates a lower incidence than in American series, but confirms that IBC has a high risk of recurrence with poor survival despite contemporary multi-modality therapy. A national strategy is required to facilitate translational research into this aggressive disease.

Does arthroplasty type influence knee joint proprioception? A longitudinal prospective study comparing total and unicompartmental arthroplasty.

Proprioception was assessed after knee replacement to compare total (TKA) to unicompartmental (UKA) knee arthroplasty. Thirty-four patients were recruited; seventeen patients underwent TKA and seventeen patients underwent UKA. The patient's age was similar in both groups. Two measures of proprioception, joint position sense (JPS) and postural sway (PS) were measured. Function was assessed using the Oxford Knee Score (OKS). Measurements were taken pre-operatively and 6 months post-operatively on both the operated and contralateral leg. Pre-operatively, no differences in JPS or PS were found between groups or between limbs in either group. Post-operatively, both groups had significant improvement of JPS in the operated limb only (20% increase). The improvement in JPS was similar in both groups. PS also improved significantly in both groups although the improvement of PS in the UKA group was twice that for the TKA group. The OKS improved by a similar amount in both groups. Both UKA and TKA result in a significant improvement in proprioception. Dynamic aspects of proprioception improve more after UKA than TKA, which may explain, in part, why UKA patients have superior functional outcome to that of TKA patients.

Does wrist immobilization following open carpal tunnel release improve functional outcome? A literature review.

Carpal Tunnel Syndrome (CTS) is a compressive neuropathy of the median nerve in the carpal tunnel. It is the most common peripheral entrapment neuropathy. The surgical management includes dividing the flexor retinaculum to decompress the median nerve. Post-operative mobilization of the wrist is controversial. Some surgeons splint the wrist for 2-4 weeks whilst others encourage early mobilization. The literature has been inconclusive as to which method is most beneficial. The purpose of this study is to review the literature regarding the effectiveness of wrist immobilization following open carpal tunnel decompression. We reviewed all published clinical trials claiming to evaluate the mobility status following open carpal tunnel release. Studies not in the English language as well as those with small number of patients (n < 30) were excluded. There were five studies that fulfilled the eligibility criteria and were included in this review. We conclude that there is no beneficial effect from post-operative immobilization after open carpal tunnel decompression when compared to early mobilization.
