Abstract:
<strong>Abstract</strong> Sweyer James MacLeod syndrome (SJMS), also known as unilateral hyperlucent lung syndrome, is a rare pulmonary disorder characterized by unilateral hypoplasia or agenesis of the pulmonary vasculature, typically affecting one lung. This results in reduced perfusion and subsequent air trapping, leading to unilateral hyperlucency on chest radiographs. Clinical presentation varies widely, often presenting asymptomatically or with recurrent respiratory infections in childhood. Diagnosis requires a combination of clinical history, imaging studies (such as chest radiography,

Abstract:
Myxofibrosarcoma is a type of soft tissue sarcoma, predominantly characterized by a high propensity for local recurrence, albeit demonstrating a relatively diminished risk for distant metastasis. Its prevalence is notably higher in elderly patients. Here, we present a case of a 73-year-old woman diagnosed with Myxofibrosarcoma. She was subjected to a whole-body bone scan using 99mTc-methylene diphosphonate (MDP) to survey potential bony metastasis. It revealed marked MDP accumulation with peripheral soft tissue uptake in the right lateral chest region of this patient. This imaging phenotype co

Abstract:
Object. Arterial embolization reduces blood loss in patients undergoing surgery for hypervascular spinal tumors. The objectives of this study were twofold: 1) to evaluate the role of magnetic resonance (MR) imaging in predicting tumor vascularity and 2) to assess the effectiveness of preoperative embolization in devascularizing these tumors. Methods. Fifty-one patients with metastatic spinal neoplasms underwent angiography, preoperative embolization, and excision of the lesion between 1995 and 2000. The MR imaging studies were correlated with tumor vascularity on angiograms. Embolization was a

Abstract:
Background: A serious concern with surgical procedures around the hip joint is iatrogenic injury of the arterial supply to the femoral head (FH) and consequent development of FH osteonecrosis. Cam-type morphology can extend to the posterosuperior area. Understanding the limit of the posterior superior extension of the femoral osteochondroplasty is paramount to avoid underresection and residual impingement while maintaining FH vascularity. Purpose/Hypothesis: The aim of this study was to quantify the impact of arthroscopic femoral osteochondroplasty on the FH vascular supply. It was hypothesize

Abstract Introduction The ability of laser speckle contrast imaging (LSCI) to provide real-time images of blood flow makes this modality appealing in the assessment of burn wounds, particularly for clinicians making treatment decisions based on burn wound depth and presumed progression. Here we present 2 preclinical studies that used LSCI to assess wound progress, both immediately and months after injury. Methods LSCI images were taken 10-40cm away from the wound and captured with a 1388x1038-pixel CCD camera. In the first study, LSCI images were captured prior to and immediately following cre

Abstract:
Abstract Abstract 857 A sufficient vascular supply is critical for proper physiologic function of solid-tissue organs and bone. Tissue vascularity is mediated concomitantly through vascular patency and angiogenesis. Recently, numerous studies have associated plasminogen, the key fibrinolytic protease of the coagulation system, with maintaining vascular patency by preventing fibrin accumulation with in the vasculature. Additionally, plasminogen may also have a direct role in angiogenesis as it has been shown in vitro that inhibitors of plasmin(ogen) suppress formation of capillary structures fr

The conjunctival microcirculation of 18 homozygous sickle cell disease (SCD) patients during steady-state, painful crisis, and postcrisis conditions was recorded on high-resolution videotapes using intravital microscopy. Selected videotape sequences were subsequently coded, frame-captured, studied, and blindly analyzed using computer-assisted image analysis protocols. At steady-state (baseline), all SCD patients exhibited some of the following morphometric abnormalities: abnormal vessel diameter, comma signs, blood sludging, boxcar blood flow phenomenon, distended vessels, damaged vessels, hem

Intramuscular myxomas (IMs) are rare myxoid tumors named for their abundance of noncollagenous mucinous stroma. IMs are benign tumors characterized by a paucity of cells, diminished vascularity, and minimal mitotic figures. The objectives of this study were to examine clinicopathologic features of IM and to discuss clinical management of these unusual soft tissue tumors. A 10-year retrospective study at Orlando Regional Medical Center was conducted from May 1993 to May 2003. A case report of a 48-year-old male with a right gluteal mass is presented.

AbstractWe present another minimally invasive technology for the treatment of hypertrophic scars and keloids: the pulsed-dye laser. Being first introduced by two groups around Schaefer (Germany) and Sorokin &amp; Lankard (USA) in 1966, the pulsed dye laser is a rather new technology. The first clinical use of pulsed-dye lasers was reported in 1983 for the treatment of naevus flammeus, and was the first laser used for the treatment of keloids in the mid-1990s.Its efficacy is based on the principle of selective photothermolysis, enabling a selective destruction of defined structures absorbing th
