– Discussion: – common acute infection which occurs most often in children; – is also common in immuno-compromised patients; – may arise from cat bite or scratch (more common w/ kittens), but may also be transmitted by flea bites; – up to 2 % of patients may … Read more
– Anatomy: – subarachnoid space is prolonged in a duralarachnoid sheath around each dorsal and ventral root, roughly to level of union of roots; – because the cord is shorter than vertebral column, nerves slope inferiorly from their levels of origin to appropriate intervertebral foramina, and the angle becomes more acute from … Read more
Discussion growth involves either or both of two processes; Appositional Growth new cartilage is formed at cartilage surface by cells derived from chondroblasts of perichondrium; w/ maturation, majority of cartilage growth is primarily appositional; Interstitial Growth increase in internal mass of cartilage by activity of chondrocytes that multiply within their lacunae; in mature cartilage, cellular turnover … Read more
– Discussion: – cartilage end plate contains no fibrillar connection w/ collagen of subchondral bone of the vertebrae; – this lack of interconnection between end plate and the vertebrae may render disc biomechanically weak against horizontal shear forces; – outer 2/3 of annulus fibrous are firmly anchored into vertebral bodies; … Read more
– Discussion: – median nerve compression syndrome at the wrist; – most common form of nerve entrapment; – first described by Paget; – references: The First Description of Carpal Tunnel Syndrome. James Paget FRS – pathophysiology: – nerve compression may result in ischemia, focal demyelination, decrease in axonal caliber, and finally axonal loss; – ref: … Read more
Discussion vital capacity < 75% (of predicted values) is seen in thoracic curves > 75 deg; significant reductions in pulmonary function are seen in curves > 80 deg; although some effect on pulmonary function can be seen at 60 deg, significant compromise is not seen until the curve is > 90 deg curves greater than … Read more

– Dosing: – contraindicated w/ clinical allergy, must periodically examine urine sediment with chronic use; – for symptomatic Paget’s Disease of bone, hypercalcemia, post-menopausal osteoporosis (in addition to supplemental calcium, adequate vitamin D intake, and adequate diet); – osteoporosis: – may be … Read more
– Discussion: – the primary frx line begins in the sinus tarsi and then extends obliquely and posteriorly to exit the medial wall; – hence the frx, travels antero-lateral to posteromedial; – the primary frx line usually extends anterior to the angle of Gissane but in some cases may extend anteriorly as far as … Read more
