Link Between Ferritin, Vitamin D, Performance, and Eating Attitudes in Female Athletes.

Iron and vitamin D deficiencies can affect athletes' health and performance. However, the epidemiology and associated risk factors remain unclear. Forty-three elite female athletics athletes (20.

Bone parameters of elite athletes with oligomenorrhea and prevalence seeking medical attention: a cross-sectional study.

Introduction: Since the definition of secondary amenorrhea is cessation of regular menses for more than 3 months, it is likely that athletes with irregular menstrual cycles, including oligomenorrhea, do not consider the condition as serious. However, the consequences of untreated oligomenorrhea have not been investigated in elite track and field athletes.

Materials And Methods: The cohort consisted of 91 elite-level track and field athletes.

Bone Metabolism, Bone Mineral Content, and Density in Elite Late Teen Female Sprinters.

With intensive training, bone injuries are a major concern for athletes. To assess bone condition, we often measure bone turnover markers, bone mineral content and density; however, in junior athletes, it is not easy to distinguish changes caused by bone injuries from those caused by growth, because the metabolism is increased in both cases. Moreover, although some studies have examined female endurance athletes, knowledge regarding changes in static and dynamic bone conditions in late teen athletes is limited.

Changes in Body Composition and Its Relationship to Performance in Elite Female Track and Field Athletes Transitioning to the Senior Division.

Many elite female athletes struggle to maintain performance while transitioning from high school to university-level (senior) sports. This study explores factors of body composition that influenced performance in elite junior female track and field athletes transitioning to the senior division. Forty-two elite female track and field athletes, ranked among the top 100 in Japan, were enrolled in this study.

Assessment of lateral subluxation in Legg-Calvé-Perthes disease: a time-sequential study of magnetic resonance imaging and plain radiography.

Lateral subluxation of the femoral head is one of the poor prognostic factors of Legg-Calvé-Perthes disease. The aim of this study was to investigate the cause of lateral subluxation of the femoral head on the basis of the changes over time on MRI. Twenty-four patients with unilateral Legg-Calvé-Perthes disease were analyzed retrospectively.

Weekly teriparatide administration for the treatment of delayed union: a report of two cases.

Unlabelled: Two cases of delayed union that were effectively treated with weekly TPTD administration are described. The effect of this therapy was observed within 4 weeks.

Introduction: In the first case, a 72-year-old woman underwent osteotomy for the treatment of hallux valgus.

Use of a rugby helmet brace for postoperative treatment of muscular torticollis.

Prior to 1992, our postoperative management for congenital muscular torticollis consisted of either plaster cast immobilization or no immobilization, depending on the patient's age and the degree of contracture. However, some patients required further surgery and developed complications. In 1992, we produced rugby helmet braces for postoperative management.

Malnutrition and disease progression in patients with rheumatoid arthritis.

To examine the changes in nutritional status during the progression of rheumatoid arthritis (RA), we studied anthropometric and biochemical variables in 97 Japanese patients with RA. Anthropometric data included body mass index (BMI), triceps skinfold thickness (TSF), and arm muscle area (AMA). Levels of albumin and cholesterol in serum, and lymphocyte count were studied as biochemical variables.

Outcomes of new pogo-stick brace for Legg-Calvé-Perthes' disease.

In 1992, the authors developed a non-weightbearing unilateral ambulatory hip abduction brace, which was named the new pogo-stick brace for unilateral Legg-Calve -Perthes' disease. The hip abduction angle of the new pogo-stick brace was adjustable 45 degrees . The advantage of this brace was that even in the sitting position, the hip abduction angle was maintained.

Usefulness of epiphyseal quotient measurement on magnetic resonance images for outcome prediction in patients with early-stage Legg-Calve-Perthes disease.

To investigate the usefulness of epiphyseal quotient (EQ) measurement for outcome prediction in patients with Legg-Calve-Perthes disease (LCPD), magnetic resonance (MR) imaging was performed in 26 patients with unilateral LCPD within 6 months of the disease onset and subsequently once every 3 months. All the patients were treated conservatively in our institute between 1990 and 1999. The mean follow-up period was 80 months.
