Background: Soft tissues tumours are tumours of mesenchymal origin excluding epithelial, skeletal tissue, reticuloendothelial system, brain coverings and solid viscera of the body. The objective of this study was to know the histopathological pattern of soft tissues tumours in the Pathology Department of Lady Reading Hospital Peshawar Khyber Pakhtunkhwa Pakistan.
Methods: This descriptive study was conducted on retrospective data from January 2009 to December 2013. All the soft tissues biopsy specimens were received in 10% formalin, labelled, gross performed, sections processed in alcohol, xylene, wax, block prepared, frozen, microtome sections taken and processed for H&E staining, mounted and reported by a Histopathologist. The inclusion criteria were any sufficient soft tissue tumour biopsy specimen of any age, sex, location in body whereas the exclusion criteria were autolysed biopsy specimen. A minimum of four and maximum of eight sections and 5 micron thick were taken from each specimen.
Results: A total of 267 soft tissues tumours biopsy specimens were received in the pathology laboratory with age range of 1-75 years, with mean age of 30.68±17.71 years. Male to female ratio was 1.13:1. Amongst the total, benign tumours were 176 (65.91%). Haemangioma, 73 (27.3%) was the commonest tumours followed by lipomas 41 (15.4%) cases. Amongst the total malignant tumours, i.e., 91 (34.08%), rhabdomyosarcoma, 35 (13.1%) was the commonest tumour followed by angiosarcoma 14 (5.2%) cases.
Conclusions: Haemangioma is the commonest benign tumour and rhabdomyosarcoma is the commonest malignant tumour in this study.

Provisional Prosthetic Outcome when Using Photogrammetry for Complete Arch Oral Implants: A Report of 111 Patient Treatments.
Oral Maxillofac Surg Clin North Am
December 2024
Private Practice, Brooklyn, NY, USA.
Complete arch oral implant treatment using photogrammetry was studied in 77 patients with 111 arches focusing on digitization of clinical records and optimization of the provisional. The aim of the study was to test the hypothesis that patient satisfaction with the provisional prosthesis during the first 4 months of care determined workflow efficiency and success. Digitization of 8 clinical records was done including centric relation, vertical dimension, esthetics, occlusion, inter-arch space, abutment selection, abutment capture, and soft tissue scan.

We carried out a cadaver study using 10 fresh-frozen adult legs and hands to explore technical feasibility and reproducibility of the free Medial Sural Artery Perforator flap and its applicability for covering soft tissue defects in the hand. A mean of 2 cutaneous perforators (1-4) were found. Each flap had a pedicle composed of a main perforator that arose from the medial sural artery.

Purpose/objective: MR-only radiotherapy planning exploits the benefits of MRI soft-tissue delineation, whilst negating the registration inaccuracies caused by MRI CT fusion. Fiducial markers have conventionally been used in prostate radiotherapy to reduce on-treatment image matching variability. However, this is an invasive procedure for the patient, and presents technical difficulties in an MR-only pathway as fiducial markers are difficult to visualise on MRI.

Background: Total hip arthroplasty is the preferred treatment for advanced hip osteoarthritis, yet complications like hip dislocation (0.2 %-10 %) persist due to factors such as implant design, positioning, surgical technique, and patient-specific conditions. Impingement between prosthetic components or the acetabulum and proximal femur is a primary cause of instability.

Magnetic Resonance Imaging (MRI) is a sophisticated diagnostic tool that utilizes the magnetic properties of biological tissue to generate detailed images of internal structures without the use of ionizing radiation. Despite its benefits in providing high-contrast images of soft tissues, the strong magnetic fields used in MRI present a unique safety challenge. Increasing MRI-related accidents and the prevalence of patients with metallic implants in recent years underscore the critical need for stringent MR safety protocols.
