ABSTRACT
Introduction: Brodie's abscess is one type of subacute osteomyelitis that can be difficult to diagnose because characteristic signs and symptoms can be subtle and non-specific. Up to 90% of Brodie's abscess cases are initially misdiagnosed, with a mean delay of 3 months to the correct diagnosis, with 50% of them misdiagnosed as tumors. Other conditions can also present quite similarly. Case Report: A 7-year-old male presented with complaints of hip pain and inability to bear weight. X-rays revealed Brodie's abscess in the proximal femur which was initially misdiagnosed as toxic synovitis with an incidental unicameral bone cyst (UBC). Conclusion: Brodie's abscess can be a diagnosis that is easily missed and should be included in the differential diagnosis when a child presents with a limp, inability to bear weight, or when a cortical lucency is seen on X-ray. There are no other cases in the literature of Brodie's abscess presenting like toxic synovitis. This case is relevant to pediatricians and orthopedists, particularly pediatric orthopedists.
ABSTRACT
To examine the relationships between exercise timing, chronotype, sleep, and mood, college students (N = 909, 19.6 ± 1.4 years, 38% female) completed questionnaires immediately after exercising. Evening exercisers had later bedtimes, poorer sleep quality, and lower sleep efficiency compared to morning exercisers. Evening chronotypes reported poorer sleep quality, greater daytime dysfunction, and less positive affect compared to morning/neither chronotypes. Chronotype moderated the relationship between exercise timing and bedtime; with each minute delay in exercise timing, bedtime was delayed by 6.1 minutes in morning-types and only 3.6 minutes in evening-types. University health initiatives should target evening exercisers to mitigate the consequences of prolonged insufficient sleep.
