Q

Developmental dysplasia (DDH) of the hip dx

A

Barlow test —‘telescoping’ movements in the long axis of the flexed and abducted thighs.

Ortolani test — flexed hips are abducted. thighs are the grasped between the thumbs in front and other fingers behind. The child’s knees are flexed and hip flexed to a right
angle. **positive sign makes audible and palpable ‘jerk’ or ‘clunk’ (not a click). **

180
Osteoporosis CRITERIA FOR TREATMENT
 Any man or woman with spine or hip fractures after minimal trauma even if the T score is more than -2.5. Treatment may be initiated without confirmation of low bone mineral density.  No fracture but score < or equal to -2.5 if risk factors are present  Osteoporosis due to secondary causes  Treatment with medications has to be started along with Calcium and Vitamin D supplementation  1200- 1500 mg/day of calcium  800- 2000 IU/day of Vitamin D Notes: Medications increase bone density in the hip approximately by 1-3% and in the spine by 4-8% over 3-4 years

All people above 50 years on corticosteroid therapy of 7.5 mg/day for at least 3 months with a T score of -1.5 or less have to be given bisphosphonates for the duration of therapy. * First-line: Alendronate and risedronate with adjuvant Calcium and Vit D. * Second-line: Zoledronic acid.

238
Lichen sclerosus
inflammatory condition of the skin. Bimodal peak: prepubertal girls, perimenopause. Pruritus is the main symptom. Main differential diagnosis is atrophic vaginitis. First-line treatment includes steroids. Lifelong surveillance with 6-monthly check-up is required due to the risk of squamous cell carcinoma of the skin
239
Diagnosis of Lichen Planus
commonly occurs as pruritic, purple/pink, polygonal papules and plaques on the skin of the extremities and trunk (cutaneous LP), but lesions may also appear on the genitalia (genital LP) (genital LP) or oral mucosa (oral LP). The lesions often have white, lacy markings known as Wickham striae and can form along the lines of minor trauma Treatment includes topical high-potency glucocorticoids topical high-potency glucocorticoids (eg, betamethasone). The disorder is self-limited and typically resolves within 2 years.
