The mycotoxin zearalenone (ZEN) is a common contaminant of swine feed which has been related to a wide range of reproductive anomalies in swine, such as pelvic organ prolapse, anestrous, and pseudopregnancy. New information is needed to understand how ZEN and related metabolites accumulate in swine reproductive tissues. We conducted a feeding study to track ZEN and the metabolite α-zearalenol (α-ZEL) in swine liver and reproductive tissues. Thirty pubertal gilts were randomly assigned one of three treatments, with ten pigs in each treatment group: (1) base feed with solvent for 21 days, (2) ZEN-spiked feed for seven days followed by base feed with solvent for 14 days, and (3) ZEN-spiked feed for 21 days...

Although secondary involvement of the broad ligament by malignant tumors arising elsewhere in the abdomen and pelvis is common, primary tumors in this location are rare. Tumors of the broad ligament can be of mesenchymal and mixed nature, such as leiomyoma, the most common neoplasm; epithelial tumors of Müllerian type, imposing a challenge to differentiate them from other adnexal masses; unique tumors from mesonephric origin; and tumor-like lesions. Most neoplasms in this region, whether benign or malignant, usually present clinically with vague symptoms and are often discovered during a routine gynecological examination...

Left ovarian vein thrombosis is a very rare and infrequent thrombotic condition that mainly occurs in the postpartum or postoperative period. We report a case of a 25-year-old para-1 woman who presented with 2 weeks of postpartum fever and dull aching abdominal pain more on the left side. Before operation, the diagnosis was left adnexal mass secondary to questionable ovarian cyst torsion and she underwent laparotomy. Her intraoperative findings revealed a firm left broad ligament mass with extension to retroperitoneum and it was difficult to demarcate the proximal end...

Nanoporous metallic networks are endowed with the distinctive optical properties of strong field enhancement and spatial localization, raising the necessity to map the optical eigenmodes with high spatial resolution. In this work, we used cathodoluminescence (CL) to map the local electric fields of a three-dimensional (3D) silver network made of nanosized ligaments and holes over a broad spectral range. A multitude of neighboring hotspots at different frequencies and intensities are observed at subwavelength distances over the network...

RATIONALE: Leiomyomatosis peritonealis disseminata (LPD) is a rare benign lesion primarily consisting of smooth muscle cells, which mostly affects premenopausal females. Here, we reported 3 females with LPD (age, 40-48 years) admitted for pelvic masses. PATIENT CONCERNS: All 3 LPD cases received laparoscopic uterine fibroid morcellation at 3, 8, and 14 years ago, respectively. Two cases were admitted for pelvic masses. One case was admitted for recurrent fibroids with pollakiuria...

Tendon inserts into bone via a fibrocartilaginous interface (enthesis) that reduces mechanical strain and tissue failure. Despite this toughening mechanism, tears occur because of acute (overload) or degradative (aging) processes. Surgically fixating torn tendon into bone results in the formation of a scar tissue interface with inferior biomechanical properties. Progress toward enthesis regeneration requires biomaterial approaches to protect cells from high levels of interfacial strain. We report an innovative tissue reinforcement strategy: a stratified scaffold containing osseous and tendinous tissue compartments attached through a continuous polyethylene glycol (PEG) hydrogel interface...

The medial patellofemoral complex, composed predominantly of the medial patellofemoral ligament, plays an important role in patellar tracking and stability. Medial patellofemoral ligament reconstruction is accordingly one of the most broadly applied surgical techniques for treating patellar instability. Orthopaedic research has demonstrated that surgeries that restore native anatomy are often more effective. The medial patellotibial ligament clearly serves an important supporting role in patellar tracking and stability, particularly in early flexion, and its inclusion in medial soft-tissue reconstructions more closely restores native patella tracking...

No topic in meniscal surgery has generated as much interest over the past decade as meniscal root tears. These rather simple tears, if left untreated, act biomechanically equivalently to a complete meniscectomy. As a result, many investigators have championed the treatment of this injury through the innovation of various surgical techniques designed to restore the biomechanical function of the meniscus to prevent the long-term clinical effects of a complete meniscectomy. Most procedures to repair the posterior meniscal root to its tibial attachment can be broadly grouped into using either a suture anchor or a transtibial bone tunnel for tibial fixation...

CONTEXT: Distinct from the muscle atrophy that develops from inactivity or disuse, atrophy that occurs after traumatic joint injury continues despite the patient being actively engaged in exercise. Recognizing the multitude of factors and cascade of events that are present and negatively influence the regulation of muscle mass after traumatic joint injury will likely enable clinicians to design more effective treatment strategies. To provide sports medicine practitioners with the best strategies to optimize muscle mass, the purpose of this clinical review is to discuss the predominant mechanisms that control muscle atrophy for disuse and posttraumatic scenarios, and to highlight how they differ...

Massive ascites as a presentation of endometriosis is a rare clinical entity that is most commonly seen in black nulliparous females. Herein, we describe a case of a 32-year-old multiparous Thai woman who presented with a two-year history of abdominal distension. Computerized tomography of the abdominopelvic region showed an infiltrative enhancing lesion involving the cul-de-sac and perirectal region with massive loculated ascites, suggesting carcinomatosis peritonei. Abdominal paracentesis was performed to yield fluid samples for evaluation, which revealed no malignant cells, and polymerase chain reaction (PCR) was negative for tuberculosis...

Gonadectomies are the most commonly performed surgical procedures in dogs. The benefits and risks associated with gonadectomy in dogs have been broadly investigated. Due to concerns associated with ovariectomy, some pet-owners and veterinarians are considering surgical alternatives which terminate the capacity for reproduction without removal of the gonads to preserve functions of the gonadal hormones. The objective of this study was to determine the feasibility of complete resection of the glandular portion of the uterus with hysterectomy (HE)...

The acromioclavicular joint is an important component of the shoulder girdle; it links the axial skeleton with the upper limb. This joint, a planar diarthrodial articulation between the clavicle and the acromion, contains a meniscus-like fibrous disk that is prone to degeneration. The acromioclavicular capsule and ligaments stabilize the joint in the horizontal direction, while the coracoclavicular ligament complex provides vertical stability. Dynamic stability is afforded by the deltoid and trapezius muscles during clavicular and scapular motion...

REVIEW
Manuel F Mosquera, Alejandro Jaramillo, Ricardo Gil, Yessica Gonzalez
Multiligament injuries of the knee (MLKI), remain an infrequent pathology especially in developed countries compared to mono-ligament lesions. In Colombia, MLKI is frequent due to the high accident rate on motorcycles. In the city of Bogota alone, about 160 motorcycle accidents have been estimated daily, being one of the cities that proportionately use this means of transport less compared to small cities. The term MLKI, include all ruptures of two or more major ligaments and therefore it has a broad spectrum of clinical presentation which creates a great challenge for the orthopedists and the surgeons envolved in this topic...

BACKGROUND: Cone beam CT (CBCT) is a widely available technique with possible indications in carpal ligament injuries. The accuracy of CBCT arthrography in diagnosing traumatic tears of the scapholunate ligament has not been reported. QUESTIONS/PURPOSES: (1) What is the diagnostic accuracy of CBCT and how does it relate to the accuracy of multislice CT arthrography and conventional arthrography in diagnosing scapholunate ligament tears? (2) What is the estimated magnitude of skin radiation doses of each method? METHODS: This secondary analysis of a previous prospective study included 71 men and women with suspected scapholunate ligament tears and indications for arthroscopy...
