An 8-month-old Caucasian infant with neurofibromatosis type 1 presented with a congenital plexiform neurofibroma and multiple café au lait spots. A pale area surrounded one of the café au lait spots located on the left gluteus in the area of dermal melanocytosis. This halolike phenomenon results from the disappearance of the Mongolian spot around the café au lait spots, revealing normal pigmented skin. This sign has been described rarely in the literature and the pathogenic mechanism is unclear.

The location of perianal abscesses and the course of the fistula follow certain patterns, especially in the relationship between external and internal openings. However, it is still not clear how the contents of the ischioanal fossa, especially the fibrous network of fat tissue, affect the route for such diseases. Ten male adult cadavers were selected for the study. Seven horizontal transverse section planes from 1cm above the pubic symphysis to the inferior border of the lesser trochanter of the femur were recorded after P45 sheet plastination...

A rare complication of diverticular disease is the formation of fistulas, most commonly either colo-vesical or colo-vaginal. We present the unusual case of a perforated sigmoid diverticulum forming a colo-gluteal fistula and presenting initially as a gluteal abscess in an otherwise asymptomatic patient. After drainage of the gluteal abscess, the patient re-presented with faecal loss from the abscess drainage site. Imaging revealed fistulous communication between the sigmoid and the left obturator internus muscle, tracking to the gluteus maximus with associated abscess and cutaneous communication to the site of previous drainage...

It has been found that Arabian and Thoroughbred horses differ in muscle fiber structure and thus in physiological changes occurring in muscles during exercise. The aim of the present study was to identify the global gene expression modifications that occur in skeletal muscle following a training regime to prepare for flat racing. Whole transcriptomes of muscle (gluteus medius) were compared between three time points of tissue collection: T0 (untrained horses), T1 (horses after intense gallop phase) and T2 (horses at the end of racing season), 23 samples in total...

Current measures of core stability utilized by clinicians and researchers suffer from several shortcomings. Three functional movement screens appear, at face-value, to be dependent on the ability to activate and control core musculature. These three screens may present a viable alternative to current measures of core stability. Thirty-nine subjects completed a deep squat, trunk stability push-up, and rotary stability screen. Scores on the three screens were summed to calculate a composite score (COMP). During the screens, muscle activity was collected to determine the length of time that the bilateral erector spinae, rectus abdominus, external oblique, and gluteus medius muscles were active...

BACKGROUND: Total hip arthroplasty (THA) through the direct anterior approach (DAA) is known to cause less muscle damage than other surgical approaches. However, more complex primary cases, such as developmental dysplasia of the hip (DDH), might often cause muscle damage. The objective of the present study was to clarify the muscle damage observed 1 year after THA through the DAA for DDH using magnetic resonance imaging. METHODS: We prospectively compared the muscle cross-sectional area (M-CSA) and fatty atrophy (FA) in muscles by magnetic resonance imaging and the Harris hip score before and at 1-year follow-up after THA through the DAA in 3 groups: 37 patients with Crowe group 1 DDH (D1), 13 patients with Crowe group 2 and 3 DDH (D2 + 3), and 12 patients with osteonecrosis as a control...
