Intramuscular haemangiomas are benign malformations of blood vessels occurring in skeletal muscles. Because of the rarity of these lesions, their deep location and variable clinical presentation, they often pose diagnostic difficulties. We herein present the first reported case of intramuscular haemangioma occurring in the levator anguli oris muscle. A 26-year-old man was referred to our Depart...

The fat mass and obesity associated (FTO) gene plays an important role in adipogenesis. However, its function during porcine intramuscular preadipocyte proliferation and differentiation remains poorly understood. In this study, we prepared the antiserum against porcine FTO (pFTO), which was used to determine its subcellular localization and tissue distribution. Our data indicated that pFTO was ...

The purpose of this study was to determine the pharmacokinetics of tramadol and its metabolite M1 after intravenous and intramuscular administration to llamas. Tramadol, a centrally acting analgesic whose efficacy is a result of complex interactions between opiate, adrenergic and serotonin receptor systems, has been used clinically to treat moderate to severe pain in humans. The pharmacokinetic...

Although hemangioma is a common benign soft-tissue tumor, the formation of intratumoral ossification is rare. Ossified intramuscular hemangioma, an infrequent benign tumor, is characterized by a progressively enlarging painless mass in the lower extremity of young female. Herein, we report a case of 27-year-old female suffered from a progressively enlarging painless mass in her left thigh. The ...

Background Free tissue transfer has evolved from muscle flaps to fasciocutaneous flaps. Dissection of the intramuscular course of feeding vessels is technically challenging. Simulation-based microsurgery skills acquisition is moving toward nonliving training models. Living porcine model or human cadavers are currently cost-ineffective methods for the early learning curve in teaching intramuscul...

A 3-year-old boy was admitted to the emergency department with right lower limb pain, edema, and livedoid discoloration that occurred immediately after intramuscular injection of benzathine penicillin. The patient was diagnosed with Nicolau syndrome, a rare complication of intramuscular injection presumed to be related to the inadvertent intravascular injection. It was first reported following ...

(18)F-FDG PET/CT has made it possible to identify many unsuspected lesions such as isolated intramuscular metastases because of its ability to detect abnormal metabolic activity in an early stage even without clinical symptoms or morphologic changes. We need to modify our routine techniques for performing biopsies of such lesions because they may not be visualized on morphologic imaging. We des...

We report on the case of a 40-year-old male who was admitted to the clinic with a large ulcer on his left buttock, 3 days after an intramuscular benzathine penicillin injection. The patient was diagnosed with Nicolau syndrome, a rare vascular complication in which a lesion develops after intramuscular injection. Symptoms are intense pain at the injection site, erythema, and livedoid dermatitis,...

The practice of aspiration before administering intramuscular immunization has been identified as causing increased pain. The latest evidence shows that this is no longer best practice. Some nurses believe that aspiration is necessary for patient safety. An education session was provided to 150 participants, most of whom were community health nurses attending an immunization conference. Nurses ...
