Explainable attention based breast tumor segmentation using a combination of UNet, ResNet, DenseNet, and EfficientNet models.

This study utilizes the Breast Ultrasound Image (BUSI) dataset to present a deep learning technique for breast tumor segmentation based on a modified UNet architecture. To improve segmentation accuracy, the model integrates attention mechanisms, such as the Convolutional Block Attention Module (CBAM) and Non-Local Attention, with advanced encoder architectures, including ResNet, DenseNet, and EfficientNet. These attention mechanisms enable the model to focus more effectively on relevant tumor areas, resulting in significant performance improvements.

EfficientUNetViT: Efficient Breast Tumor Segmentation Utilizing UNet Architecture and Pretrained Vision Transformer.

This study introduces a sophisticated neural network structure for segmenting breast tumors. It achieves this by combining a pretrained Vision Transformer (ViT) model with a UNet framework. The UNet architecture, commonly employed for biomedical image segmentation, is further enhanced with depthwise separable convolutional blocks to decrease computational complexity and parameter count, resulting in better efficiency and less overfitting.

Correlation of maximal nasal septal deviation with deviation at the maxillary insertion.

Purpose: It is unclear if septal deviation at the insertion points to the nasal cavity is associated with the overall septal deviation. This study aimed to assess septal deviation at the cribriform plate (CP) and maxillary crest (MC) using CT scans and to see if there was any correlation with overall septal deviation.

Methods: All consecutive CT sinus scans between January 2020 and December 2021 were retrospectively reviewed.

A-T Flap for Reconstruction of Nasal Dorsum Skin Defects.

Reconstruction of nasal defects can be challenging, especially when encountering larger defects. We describe the use of a single-stage conversion of an 'A' shaped defect to a 'T' shaped scar of large nasal skin defects in the cosmetically sensitive supra-tip and supra-alar regions. This study aimed to determine whether an A-T flap is a suitable option for nasal reconstruction and if so where and what size defects it can be used for.

Gigantic undifferentiated pleomorphic sarcoma (UPS) of breast in a woman: A rare case report.

Introduction And Importance: Undifferentiated pleomorphic sarcoma (UPS), also known as malignant fibrous histiocytoma, is a rare mesenchymal tumor that occurs mostly in the soft tissue of the limbs and retroperitoneum. UPS of the breast is extremely rare, with less than 20 cases reported in the literature.

Case Presentation: We present a case of UPS of the right breast in a 56-year-old female.
