    Notes: Foot loading patterns and neuromuscular function of both limbs during walking were investigated on 25 patients with limb length discrepancy. Plantar pressures and 2-D ground reaction forces were recorded simultaneously with electromyographic activities at two different walking speeds. Bilateral comparison indicated that moderate limb length discrepancies resulted in asymmetrical gait patterns. The duration of the stance phase was reduced in the short limb in both walking speeds. The vertical ground reaction force (F) in the push-off phase was greater in the long limb both at normal (1.33 (SO, 0.05 BW) vs. 1.29 (SD, 0.09 BW)) (P=0.0027) and fast walking speed (1.55 (SD, 0.11) vs. 1.48 (SD, 0.15 BW)) (P=0.001). Peak plantar pressures were higher under the big toe in the long leg and the heel-off occurred faster. The push-off phase was initiated earlier in the short leg. The maximum isometric torque of the long limb was considerably greater (673 Nm vs. 239 Nm) (P=0.026). The results imply that the loading of the long limb is greater and the foot loading patterns shifted more to the forefoot in the long, limb to compensate walking disturbances caused by limb length discrepancies.

    Intralobar pulmonary sequestration occurring without alteration of pulmonary parenchyma (1981)
    Springer

    Notes: Abstract Typical changes of lung sequestration, including the scimitar sign, were seen on plain films in the left lower lobe. At aortography vasculature of a pulmonary sequestration was seen located paravertebrally in the left posterobasal segment. The arterial supply arose from a division of the thoracic aorta above the diaphragm; venous drainage was to the pulmonary veins. No pulmonary parenchymal changes were detected in the sequestration after resection, nor was there an extrapleural component of the sequestration.

    MRI in late sequelae of Penhes' disease: imaging findings and symptomatology in ten hips (1996)
    Springer
    Pediatric radiology 26 (1996), S. 640-645

    Topics: Medicine
    Notes: Abstract Five painful (group A) and five symptomless (group B) hips in nine patients with late sequelae of Perthes' disease were studied with plain radiography and magnetic resonance imaging (MRI) in order to correlate MRI findings with symptomatology. The unaffected hips were also studied. In group A hips, poor congruence of the articular cartilage surfaces was present in three of five cases, whereas good congruence was found in all group B hips. In one spherical but painful hip (group A), MRI revealed a protuberance in the anterolateral cartilage of the femoral head. The joint cartilage in group A and B hips was, on average, 0.5 and 1.5 mm thicker, respectively, than the cartilage in the unaffected hips. The lateral joint capsule was, on average, 3.0 mm thicker in group A hips than in the unaffected hips (P 〈 0.05), which possibly reflects reactive changes due to chronic irritation in the painful hips. The mean joint capsule thickness differed by only 0.5 mm between the unaffected and group B hips. Mean anterior acetabular coverage by MRI was 97 % in group A and 98 % in group B, while in the unaffected hips mean anterior coverage was 102 %. In an aspherical painful hip, MRI revealed a juxta-articular cyst not visible by radiography. A symptomless intra-articular fragment, due to osteochondritis dissecans, was well visualized with MRI. MRI is recommended for evaluation of pain in hips with late sequelae of Perthes' disease. It may show abnormalities in bony structures, as well as in joint capsule and cartilage.

    Spinal deformity induced by radiotherapy for solid tumours in childhood: A long-term follow up study (1993)

    Notes: Abstract A group of 44 individuals were re-evaluated at a median follow up time of 19 years after radiotherapy for childhood cancer involving some part of the vertebral column. The median age at diagnosis was 2.6 years. The diagnoses included Wilms' tumour (n=24), neuroblastoma (n=9) and other solid tumours (n=11). Scoliosis with or without kyphosis was the most common spinal deformity and was found in 40/44 patients. The apex of the major curvature was on the lumbar vertebral body 1–3 in 23 cases. The kyphosis and lordosis were greater in the subjects with tumour other than Wilms' (P=0.04 both). Of the subjects restudied, 35 had detectable local soft tissue atrophy in the region of irradiation. Scoliotic deformity often enhanced cosmetic handicap/defect. Five subjects reported some symptoms related to the back; they had more severe scoliotic and kyphotic deformity (P=0.02). Spinal abnormalities were common in these survivors, but subjective complaints were unusual.

    Disc herniation in the lumbar spine during growth: Long-term results of operative treatment in 18 patients (1997)

    Notes: Abstract We studied 18 patients who had undergone surgery for herniated lumbar discs between the ages of 11 and 17 years. The inclusion criteria for girls was an age of 15 years or below and for boys 17 or below at surgery. The mean follow-up time was 10 years and the clinical outcome was good. Age at surgery and length of the follow-up had no effect on the result. The radiological disc height at follow-up did not correlate with the follow-up time or age of the patient at operation. MRI scans at follow-up from ten patients operated at less than 15 years of age revealed multilevel disc degeneration but favourable clinical results.

    Modelling the impacts of secondary organic aerosol formation on shallow clouds (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-06-13
    Description: UCLALES-SALSA is a detailed high-resolution model for studying aerosol-cloud interactions in shallow clouds. The model is based on a large eddy simulator UCLALES which was coupled with a sectional aerosol-cloud microphysics module SALSA. The model was recently coupled with a Secondary Organic Aerosol (SOA) formation module. The SOA module contains lumped Volatile Organic Compound (VOC) categories such as biogenic monoterpenes and isoprene, and anthropogenic aromatics. Their oxidation produces Semi-Volatile Organic Compounds (SVOCs), which partitioning between vapor and particle phases. The partitioning is modelled using a Volatility Basis Set (VBS) approach. The module also contains aqueous-phase SOA (aqSOA) formation.The model was tested using a LES setup based on in-situ stratocumulus cloud observations from Kuopio, Finland. The observed low aerosol number concentrations and high aerosol organic factions indicated that SOA formation could have a significant impact on cloud properties. First, by allowing the partitioning of SVOCs the condensed-phase organic aerosol (SOA) concentration becomes temperature dependent. In this case the temperature decreased due to radiative cooling, which increased the SOA mass and the cloud droplet number concentration (CDNC). Surface VOC emissions are important for maintaining SOA production as the reactive VOCs are otherwise consumed rapidly. Thanks to the effective vertical mixing, surface emissions had direct impact on CDNC. Finally, the impact of aqSOA formation depends mainly on anthropogenic emissions because VOC emissions from local boreal forests are dominated by monoterpenes which are not effective aqSOA precursors.
