The extent of scarring or renal interstitial collagen deposition in chronic kidney disease (CKD) can only be ascertained by highly invasive, painful and sometimes risky, tissue biopsy. Interestingly, while CKD-related abnormalities in kidney size can often be visualized using ultrasound, not only does the ellipsoid formula used today underestimate true renal size, but the calculated renal size does not inform tubulointerstitial collagen content. We used coronal kidney sections from healthy mice and mice with kidney disease to develop a new formula for estimating renal parenchymal area...

Background Split-bolus computed tomography (CT) is a recent development in trauma imaging. Instead of multiple scans in different contrast phases after a single contrast bolus, split-bolus protocols consist of one single scan of the thorax and abdomen after two or three contrast injections at different points of time. Purpose To evaluate and compare image quality and injury findings of a new triple-split-bolus CT (TS-CT) protocol of thorax and abdomen with those of a portal venous phase CT (PV-CT) in the same patient group...

PURPOSE: This study aimed to evaluate the biomechanical stability of different fixation techniques for fractures of the acetabular posterior wall. The hypothesis was that a reconstruction plate, combined with compression screw fixation and a plate placed lateral to the screws, would achieve a higher peak load to failure and stiffness and reduced gapping during cycle loading than other fixation techniques. METHODS: A total of 24 Sawbone pelvis models were created with simulated fractures at the posterior wall of the acetabulum...

A 62-year-old man presented to our department with abdominal pain and diarrhea for 3 weeks on a background of previous branched endovascular repair for a thoracoabdominal aneurysm. A triple-phase computed tomography scan of his abdomen and pelvis showed a large aortocaval fistula caused by a type III endoleak from a dislodged superior mesenteric artery stent. He was successfully treated with a BeGraft (Bentley Innomed, Hechingen, Germany) by using an endovascular technique.

Lymphangioleiomyomatosis (LAM) is a rare and progressive neoplastic disease of young woman, characterized by the proliferation of abnormal smooth muscle-like cells (LAM cells) in the lungs and axial lymphatics. A 44-year-old woman was referred to our hospital because pleural effusion was detected during a health checkup. She had chylothorax, chylous ascites, and chyluria, and her computed tomography scan showed a solid tumor in the pelvis. Surgical biopsy was performed; she was diagnosed as having LAM. We could not control the fluid collection and chyluria using standard medical treatments...

The US FDA granted accelerated approval to pembrolizumab for microsatellite instability-high and mismatch repair deficient cancers. The response of programmed death-1 blockade in mismatch repair proficiency (pMMR) colorectal cancer is very poor, however, whether such treatment is effective in pMMR nasopharyngeal carcinoma (NPC) remains unknown. We report a case of a 51-year-old man with NPC. PET-CT scan revealed a space-occupying lesion in the left lung, and the pathologic result confirmed the occupying lesion originated from NPC...

Introduction: Percutaneous nephrolithotomy (PCNL) is traditionally performed with the patient in the prone position for large renal calculi. However, anesthetic limitations exist with the prone position. Similarly, the supine position is associated with poorer ergonomics due to the awkward downward position of the renal tract, a smaller window for percutaneous puncture, and a higher risk of anterior calyx puncture. This study aimed to demonstrate the feasibility and safety of lateral-PCNL in managing large renal calculi without the disadvantages of prone and supine positions...

Tuberous-sclerosis-complex (TSC) is associated with a high lifetime risk of severe complications. Clinical manifestations are largely variable and diagnosis is often missed. Sclerotic-bone-lesions (SBL) could represent a potential imaging biomarker for the diagnosis of TSC. In this study, computed tomography (CT) data sets of 49 TSC patients (31 females) were included and compared to an age/sex matched control group. Imaging features of SBLs included frequency, size and location pattern. Sensitivities, specificities and cutoff values for the diagnosis of TSC were established for the skull, thorax, and abdomen/pelvis...

Biological sex estimation of skeletal remains is essential in forensic and archaeological analyses. Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400)...

Peripheral T cell lymphomas are a heterogeneous group of post-thymic, mature lymphoid malignancies, accounting for approximately 10-15% of all non-Hodgkin's lymphomas. Hepatosplenic T-cell lymphoma (HSGDTCL) is a rare entity, which is characterized by primary extra nodal disease with typical sinusoidal or sinusal infiltration of the liver and the spleen, respectively by expression of the T-cell receptor γδ chain, and by a number of other frequent clinicopathologic features, including aggressive course of disease...

Physical activity plays a crucial role in bone mass acquisition during childhood and adolescence, with weightbearing and high-impact sport activities being more beneficial. This study sought to evaluate the impact of different sports activities on bone mineral density and content in male Portuguese athletes. Seventy adolescent boys (aged 12-15 years) including 28 futsal players (FG), 20 swimmers (SG) and 22 non-athletic adolescents used as control subjects (CG), participated in the current study. Areal bone mineral density (aBMD) and areal bone mineral content (aBMC) were measured by dual energy x-ray absorptiometry (DEXA)...

We present a computer program designed to visualize and interact with three-dimensional models of the main anatomical structures of the female pelvis. They are reconstructed from serial sections of corpse, from the Visible Human project of the Medical Library of the United States and from serial sections of high-resolution magnetic resonance. It is possible to represent these three-dimensional structures in any spatial orientation, together with sectional images of corpse and magnetic resonance imaging, in the three planes of space (axial, coronal and sagittal) that facilitates the anatomical understanding and the identification of the set of visceral structures of this body region...
