Placement of ilio-sacral screws in fusionless technique for pediatric neuromuscular scoliosis utilizing planning software, in conjunction with intraoperative navigation, results in a safer optimal screw: a CT-based study.

Purpose: The insertion of ilio-sacral (IS) screws for distal anchoring in the instrumentation of pediatric neuromuscular scoliosis (NS) presents a significant challenge, often leading to elevated rates of complications. Utilizing computed tomography (CT) navigation and preoperative planning technology is proposed as a potential solution to mitigate these challenges. This study aims to assess the precision of IS screw placement through CT-graphic measurements, both with and without preoperative planning, followed by navigated IS screw insertion, in pediatric neuromuscular scoliosis.

Pathogenic variants in HGF give rise to childhood-to-late onset primary lymphoedema by loss of function.

Developmental and functional defects in the lymphatic system are responsible for primary lymphoedema (PL). PL is a chronic debilitating disease caused by increased accumulation of interstitial fluid, predisposing to inflammation, infections and fibrosis. There is no cure, only symptomatic treatment is available.

Estimation of antimicrobial resistance of Belgium, 2022.

BackgroundAntimicrobial resistance (AMR) of (MG) is a growing concern worldwide and surveillance is needed. In Belgium, samples are sent to the National Reference Centre of Sexually Transmitted Infections (NRC-STI) on a voluntary basis and representative or robust national AMR data are lacking.AimWe aimed to estimate the occurrence of resistant MG in Belgium.

Two Years of Genomic Surveillance in Belgium during the SARS-CoV-2 Pandemic to Attain Country-Wide Coverage and Monitor the Introduction and Spread of Emerging Variants.

An adequate SARS-CoV-2 genomic surveillance strategy has proven to be essential for countries to obtain a thorough understanding of the variants and lineages being imported and successfully established within their borders. During 2020, genomic surveillance in Belgium was not structurally implemented but performed by individual research laboratories that had to acquire the necessary funds themselves to perform this important task. At the start of 2021, a nationwide genomic surveillance consortium was established in Belgium to markedly increase the country's genomic sequencing efforts (both in terms of intensity and representativeness), to perform quality control among participating laboratories, and to enable coordination and collaboration of research projects and publications.

Malignant pleural mesothelioma with an EML4-ALK fusion: Expect the unexpected!

Case report of malignant pleural mesothelioma with an ALK gene rearrangement, detected by FISH and confirmed by RNA-based next-generation sequencing. The co-occurrence of ALK gene fusions with the more common genetic alterations in CDKN2A, NF2 and BAP1 has, to our best knowledge, not yet been described in malignant mesothelioma. Furthermore, this unexpected finding could suggest a potential target for therapy in this subset of malignant mesotheliomas.

Clinical Practice Experiences Using a Professional Diabetes Management Ecosystem During COVID.

Background: Challenges of patient care in diabetes were exacerbated by COVID, undermining the ability of patients to engage in-person with health care professionals (HCPs). To combat this, there has been accelerated adoption of telemedicine to support patient and provider connectivity.

Methods: We collated survey information regarding telemedicine from 21 European clinical institutions.

Recent Advances in Ultrasound Technology: Ultra-High Frequency Ultrasound for Reconstructive Supermicrosurgery.

Background:  Currently, microsurgeons are in the era of supermicrosurgery and perforator flap reconstruction. As these reconstructions frequently utilize vessels that are smaller than a single millimeter, understanding of location of lymphatic vessels and perforator anatomy preoperatively is essential. To change with the times, the role of ultrasound has changed from just an adjunct to primary imaging of the choice in reconstructive supermicrosurgery.

Intraoperative Real-Time Visualization of the Lymphatic Vessels Using Microscope-Integrated Laser Tomography.

Background:  Detection and selection of the lymphatic vessels are important for maximizing therapeutic efficacy of lymphaticovenular anastomosis (LVA). Some imaging modalities have been reported to be useful for intraoperative identification of the lymphatic vessels, but they have limitations. In this article, we present new capabilities of intraoperative laser tomography, which was used to evaluate the lumen of the lymphatic vessel and to validate the patency of anastomosis.

The path to a better biomarker: application of a risk management framework for the implementation of PD-L1 and TILs as immuno-oncology biomarkers in breast cancer clinical trials and daily practice.

Immune checkpoint inhibitor therapies targeting PD-1/PD-L1 are now the standard of care in oncology across several hematologic and solid tumor types, including triple negative breast cancer (TNBC). Patients with metastatic or locally advanced TNBC with PD-L1 expression on immune cells occupying ≥1% of tumor area demonstrated survival benefit with the addition of atezolizumab to nab-paclitaxel. However, concerns regarding variability between immunohistochemical PD-L1 assay performance and inter-reader reproducibility have been raised.

Successful treatment of breast cancer-related breast lymphedema by lymphovenous anastomosis in a male patient.

Men, as well as women may develop breast lymphedema following breast cancer treatment. Microsurgically performed lymphovenous anastomosis (LVA), an effective treatment for lymphedema of the extremities, has also been successfully applied to breast lymphedema. Here we report the first case of breast lymphedema secondary to male breast cancer, treated with supermicrosurgical LVA.

Ultra High-frequency Ultrasonographic Imaging with 70 MHz Scanner for Visualization of the Lymphatic Vessels.

Background: Identification and localization of functional lymphatic vessels are important for lymphaticovenular anastomosis. Conventional high-frequency ultrasound (CHFUS) has been reported to be useful for them, but it has some disadvantages. In this article, we present new capabilities of ultra high-frequency ultrasound (UHFUS) for imaging of the lymphatic vessels, which may overcome the weakness of CHFUS.

Lymphatic supermicrosurgery for the treatment of recurrent lymphocele and severe lymphorrhea.

Background: Lymphocele and lymphorrhea are frequent complications after lymph node excision. Recurrent lymphoceles and intractable lymphorrhea are particularly difficult to treat conservatively. We describe the outcomes of four patients with recurrent lymphocele and nine patients with persistent lymphorrhea that were treated by supermicrosurgery.

Supermicrosurgical lymphaticovenous anastomosis for a patient with breast lymphedema secondary to breast cancer treatment.

Breast lymphedema (BLE) has been reported as a complication following breast cancer treatment. As for extremity lymphedema treatment, supermicrosurgical lymphaticovenous anastomosis (LVA) is considered an option for the treatment of progressive BLE refractory to conservative treatments, but no case has been reported so far. We report the first case of BLE successfully treated with supermicrosurgical LVA.

Liver failure after long-limb gastric bypass.

Liver failure is reported with increasing frequency in patients who underwent bariatric surgery for morbid obesity. In most cases, liver transplantation is the only possible treatment to avoid fatal outcome. Although most cases are observed after older bariatric surgery techniques characterized by high malabsorption rates, we report on a 38-year-old woman who developed liver failure seven months after long-limb gastric bypass.

Uterine perforation in women using a levonorgestrel-releasing intrauterine system.

Objective: To determine an estimated incidence of uterine perforations related to the insertion of a levonorgestrel-releasing intrauterine system (LNG IUS) and to identify possible risk factors.

Design: Retrospective, case report study.

Setting: Hospitals in Limburg, the Netherlands.
