question:
Abstract: Three patients with postcholecystectomy unilateral hepatic duct stricture and subsequent liver atrophy were treated conservatively, with a successful outcome of up to three years follow up. A better understanding of the pathophysiological sequelae of segmental hepatic duct obstruction suggests that in such circumstances reconstructive surgery, with its attendant risks, may not invariably be necessary. 
Question: Does the abstract contain any numerical data?
answer:
No


question:
Abstract: Spinal deformity is a relatively common disorder, particularly in teenage girls. Early detection is possible by a simple, quick visual inspection that should be a standard part of the routine examination of all preteen and teenage patients. Follow-up observation will reveal those curvatures that are progressive and permit orthotic treatment to prevent further increase in the deformity. Spinal fusion offers correction and stabilization of more severe degrees of scoliosis.

question:
Abstract: Although osteoarthritis (OA) generally is considered a disorder of mechanical origin, the common occurrence of chronic mononuclear cell infiltrates in the synovium in conjunction with immunofluorescent evidence for immune-reactant products in cartilage of surgical case specimens (knees, hips, and peripheral joints) has suggested the local involvement of immune processes in the arthritis. Further, the findings of polyarthropathy in the majority of these cases have indicated the propensity for a systemic disorder. Wide variations were noted in both synovial and cartilage immune changes, quite different to those found in rheumatoid arthritis, along with the frequent asymptomatology of the many joints involved. These features, with and without other causative factors, suggest that immune reactions of local and/or systemic origin occur at times in a population at risk for joint degradation.
