IMPORTANCE: Mild traumatic brain injury (mTBI) is the signature injury experienced by military service members and is associated with poor neuropsychiatric outcomes. Yet, there is a lack of reliable clinical tools for mTBI diagnosis and prognosis. OBJECTIVE: To examine the white matter microstructure and neuropsychiatric outcomes of service members with a remote history of mTBI (ie, mTBI that occurred over 2 years ago) using diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI)...

Architectural distortion (AD) is one of the most common findings on mammograms, and it may represent not only cancer but also a lesion such as a radial scar that may have an associated cancer. AD accounts for 18-45% missed cancer, and the positive predictive value of AD is approximately 74.5%. Early detection of AD leads to early diagnosis and treatment of the cancer and improves the overall prognosis. However, detection of AD is a challenging task. In this work, we propose a new approach for detecting architectural distortion in mammography images by combining preprocessing methods and a novel structure fusion attention model...

Hand Surgery is a specialized branch of Plastic and Reconstructive surgery. There are many conditions that require hand surgery, for example, congenital deformity, electric or flame burn, mechanical or road traffic injury, and post burn or post traumatic deformity. A retrospective observational study was conducted in the department of Burn and Plastic surgery, Mymensingh Medical College Hospital, Bangladesh during a 2 years period extending from 9th September 2021 to 8th September 2023. The objective of this study was to see the hand surgery status in a tertiary hospital of Bangladesh during the post Covid pandemic period...

PURPOSE: Capsular contracture is a rare but serious complication of silicone implant-based augmentation rhinoplasty. When severe, the contracture can affect all layers of the nose, causing significant scarring and disfigurement. There is currently no standardized method of evaluating contracted noses and a paucity of literature on the treatment of severe contracture. Therefore, this study aimed to establish a comprehensive grading system and treatment approach for patients with nasal contracture secondary to silicone implant-based rhinoplasty...

Background: Radial scars are more commonly identified on digital breast tomosynthesis (DBT) than on digital mammography (DM). Nonetheless, universal guidelines for radial scar management in the current era of DBT are lacking. Objective: To determine the upstaging rates of screening DBT-detected radial scars with and without atypia and to identify features related to upstaging risk. Methods: This retrospective study included patients who underwent core-needle biopsy (CNB) showing a radial scar after screening DBT and DM from January 1, 2013, to December 31, 2020...

Objective: To explore the effect of accurately localized mini anterolateral thigh perforator flap in repairing medium-sized skin and soft tissue defects in fingers. Methods: The study was a retrospective observational study. From December 2019 to September 2022, 15 patients with medium-sized skin and soft tissue defects who met the inclusion criteria in fingers were admitted to the Second Affiliated Hospital of Wenzhou Medical University, including 12 males and 3 females, aged 23 to 62 years. After debridement, the wounds were all accompanied by exposed tendons, bones, vessels and nerves, with an area from 4...

OBJECTIVE: Evaluate the incidence and outcome of new enhancing findings on breast MRI after neoadjuvant chemotherapy (NAC). METHODS: This IRB-approved retrospective review included women with breast cancer undergoing MRI to evaluate NAC response at our institution from January 1, 1998 to March 3, 2021. Post-NAC MRIs given BI-RADS 4 or 5 with new enhancing findings were identified. Patients were excluded if they lacked pretreatment MRI or insufficient follow-up, or if the finding was a satellite of the primary tumor...

BACKGROUND: Dermoscopy is a non-invasive, cost-effective tool useful in the assessment of pigmented lesions. The aim of this study was to analyze the dermoscopic features in excised melanomas in a tertiary hospital in Brazil and the influence of Breslow thickness on the dermoscopic features observed. METHODS: An observational, cross-sectional study in which dermoscopic images of 43 melanomas were evaluated. The patients were divided into three groups: in situ, thin invasive melanoma (Breslow thickness <1 mm), and thick invasive melanoma (Breslow thickness ≥1 mm)...

BACKGROUND: Radial scars/radial sclerosing lesions (RS) are benign breast lesions identified on core needle biopsy (CNB) which can upgrade to malignancy at excision. There is limited data on RS detection and upgrade rates with more sensitive imaging such as magnetic resonance imaging (MRI) and none during their detection for breast cancer workup and its implication on patient treatment decisions. METHODS: A retrospective institutional study of RS diagnosed on CNB between January 2008 and December 2017 was conducted...

BACKGROUND: The initial idea of functional tissue replacement has shifted to the concept that injected cells positively modulate myocardial healing by a non-specific immune response of the transplanted cells within the target tissue. This alleged local modification of the scar requires assessment of regional properties of the left ventricular wall in addition to commonly applied measures of global morphological and functional parameters. Hence, we aimed at investigating the effect of cardiac cell therapy with cardiovascular progenitor cells, so-called cardiac induced cells, on both global and regional properties of the left ventricle by a multimodal imaging approach in a mouse model...

BACKGROUND: Patients requiring coronary intervention after acute myocardial infarction, with decompensated heart failure and multiple co-morbidities, present a challenging clinical scenario. Addressing such high-risk cases has been a marked increase in the simultaneous support using microaxial flow pump devices, providing a crucial haemodynamic support during procedures. CASE SUMMARY: We report the case of a 58-year-old man, with a non-ST-segment elevation myocardial infarction in the context of a peripheral vascular surgery...

The radial forearm free flap (RFFF) is commonly used in the reconstruction of oral cancer patients. Traditional RFFF (TRFFF) techniques, which often require a secondary donor site to repair the forearm defect, may result in a scar extending to the dorsal hand. This can lead to significant functional and aesthetic concerns in the forearm. We designed a modified RFFF (MRFFF) that incorporates a glasses-shaped flap and features deep venous drainage. To evaluate its effectiveness we conducted a retrospective chart review of 105 patients with oral squamous cell carcinoma who underwent reconstructive surgery between 2018 and 2022...

Introduction: Cardiac resynchronisation therapy is ineffective in 30-40% of patients with heart failure with reduced ejection fraction. Targeting non-scarred myocardium by selecting the site of latest mechanical activation using echocardiography has been suggested to improve outcomes but at the cost of increased resource utilisation. The interval between the beginning of the QRS complex and the local LV lead electrogram (QLV) might represent an alternative electrical marker. Aims: To determine whether the site of latest myocardial electrical and mechanical activation are concordant...

Forearm skin flaps are widely used to reconstruct oral cancer due to their advantages, such as vascular stability, simple preparation, and a high success rate. However, traditional forearm skin flaps have shortcomings: the donor site requires grafting, which increases surgical trauma by creating a second surgical area, and the scarring at the donor site significantly affects the esthetics of the forearm. Therefore, we have designed a new ^-shaped radial forearm skin flap, in which the flap is designed as 2 semi-elliptical subunits...

PURPOSE: Gracilis muscle flaps are useful to cover defects of the hand. However, there are currently no studies describing outcome measurements after covering soft tissue defects using free flaps in the hand. AIM: To analyze mid-term results of gracilis muscle flap coverage for defects on the hand, with regard to functional and esthetic integrity. METHODS: 16 patients aged 44.3 (range 20-70) years were re-examined after a mean follow-up of 23...

OBJECTIVE: To explore the feasibility of the golden-angle radial sparse parallel (GRASP) dynamic magnetic resonance imaging (MRI) technique in predicting the intraoperative bleeding risk of scar pregnancy. METHODS: A total of 49 patients with cesarean scar pregnancy (CSP) who underwent curettage and GRASP-MRI imaging were retrospectively selected between January 2021 and July 2022. The pharmacokinetic parameters, including Wash-in, Wash-out, time to peck (TTP), initial area under the curve (iAUC), the transfer rate constant (Ktrans), constant flow rate (Kep), and volume of extracellular space (Ve), were calculated...

Benign breast disease (BBD) is a heterogenous group of lesions often classified as nonproliferative or proliferative, with the latter group further categorized based on the presence of atypia. Although nonproliferative lesions are more common, the risk of breast cancer is elevated in women with proliferative lesions. Historically, the majority of proliferative lesions were excised due to concern for future and/or concomitant breast cancer at the site of the index lesion. However, contemporary data suggest that the risk of cancer associated with various proliferative lesions may be lower than previously thought, and management of BBD has become more nuanced...

OBJECTIVE: Describe features of iatrogenic "overshoot" nerve injuries on ultrasound and MRI, which occur when an instrument passes through the bone and injures the nerve after it penetrates the opposite cortex. MATERIALS AND METHODS: After a keyword search of the radiology database at a tertiary care orthopedic hospital from January 2016 to December 2022, those fulfilling the inclusion criteria of (1) instrumentation through the bone during surgery, (2) acute neuropathy immediately after surgery, (3) nerve injury confirmed on electrodiagnostics, and (4) imaging consistent with overshoot nerve injury were included...
