Min Lee, Soon Chul Kim
RATIONALE FOR THIS CASE REPORT: Many children are hospitalized because of foreign body ingestion. In such circumstances, the gastroenterologist must consider the timing of ingestion; the size, type, and location of the object ingested; and the patient's symptoms. But appendiceal foreign body in infant is very rare. PATIENT CONCERNS: A 12-month-old boy visited because of swallowing small objects 2 weeks ago. Three small beads were found in the right lower quadrant on abdominal radiography...

The temporomandibular joint (TMJ) is a condylar synovial joint that, together with the masticatory muscles, controls mandibular movement during mastication. The rabbit is often used as a model species for studying the mechanisms of TMJ diseases, and in regenerative research. However, there are significant differences between rabbit and human TMJs that should be taken into account before using this model for experimental research. Here, we use several analytical approaches (radiography, computed tomography and magnetic resonance imaging) to enable a detailed description and analysis of the rabbit TMJ morphology...

Body packing refers to the intracorporeal concealment of illicit drugs. Here we report the case of a 55-year-old body packer who presented with palpitations, visual hallucinations, and a sense of impending death. Abdominal radiography demonstrated five ovoid foreign bodies overlying the rectum. At subsequent gastrotomy and cecotomy, thirty-eight cocaine-containing packets were retrieved from the stomach and ascending colon as well as from the rectum. As the contraband market evolves new techniques to evade detection, evaluation of the burden of body packer ingestion has become increasingly challenging...

Post-pregnancy osteoporosis is a rare condition with little known pathophysiology. Most cases are diagnosed in the late stage of pregnancy or in the post-partum while breastfeeding, particularly in first pregnancy. Vertebral fractures are most commonly observed and characterized by prolonged severe pain and functional limitations. Measurements of bone mineral density(BMD)of the lumbar spine and proximal femur with dual energy X-ray absorptiometry(DXA)are the clinical methods most commonly used for no fracture women...

Marna du Plessis, Lorraine du Toit-Prinsloo
Air embolism (AE) is considered a rare event and can be either iatrogenic or traumatic. Various post-mortem methods to detect AE exist, of which radiology is preferred. The presence of air in the heart can be demonstrated using special dissection techniques where the heart is opened under water or by needle puncture from a water-filled syringe. Three cases of blunt-force head injury are presented herein, with AE being diagnosed by conventional radiography using a Lodox Statscan® full-body digital X-ray machine in all cases...

Autologous bone grafting is an established method to overcome bone deficiencies in primary total knee arthroplasty (TKA). However, recently, metal augments have been used by many surgeons. Although autologous bone grafting is a common technique, few large studies have described its success in achieving bone union in primary TKA. The goal of this study was to evaluate primary TKA with autologous bone grafting for tibial defects. A total of 68 knees that had undergone arthroplasty with autologous bone grafting with more than 1 year of follow-up were evaluated...

Our purpose is to provide simple guidelines for the diagnosis and early care of patellofemoral disorders. Any clinician who treats knee problems, including family practitioners, rheumatologists, orthopedic surgeons, or physical therapists, must know how to make the correct diagnosis, or at least a presumptive diagnosis, at the initial visit. This can avoid unneeded and costly tests, ineffective treatment, and even damaging exercises and unnecessary surgery. The diagnosis of patellofemoral disorders is confusing because they can have many causes...
