Secondary resurfacing of the patella in total knee arthroplasty
No full textAnterior knee pain following primary total knee arthroplasty is common and can be difficult to treat satisfactorily. We reviewed 28 consecutive patients (29 knees) who underwent secondary resurfacing of the patella for persistent anterior knee pain and report on the results. Mean follow-up was 28 months (range12-61) with no cases lost to follow-up. Oxford knee scores, range of motion, the patient's assessment of outcome and overall satisfaction were recorded. Seventeen out of 19 (59%) felt their knee was better following patellar resurfacing, 10 out of 29 (34%) felt it was the same and two out of 29 (7%) felt it was worse. There was a significant improvement in Oxford knee scores (p < 0.001) and significant increase in patient satisfaction (p < 0.001) following secondary resurfacing. While secondary resurfacing of the patella does not provide the solution for every case of anterior knee pain following total knee joint replacement, in greater than 50% of cases it can be effective at relieving symptoms and in this series carries a low risk of worsening symptoms or complications

The population dynamics of Patella vulgata and other limpets.
No full textPhDUseful generalisations can be made about limpet populations
in much the same way as they can about individual animals.
These generalisations can be expressed quantitatively and formed
into a framework of population dynamics. In Patella vulgata
populations a greater mean size (defined as the 50% accumulative
weight size) indicates (i) a faster growth rate, (ii) a larger
maximum size, (iii) an increased mortality rate, (iv) decreased
mean and maximum life spans, (v) an increased settlement rate,
(vi) an earlier and more rapid seasonal maturation of the gonad,
(vii) a larger number of eggs produced per female and per unit
weight, (viii) a lower radula ratio and a flatter shell at the
mean size, than would be found in a population with a smaller
mean size. The timing of sexual maturity and of sex change is
independent of these correlated features of population dynamics.
The correlations were established by the detailed study of four
populations at Mount Batten, Plymouth; and verified by experimental
alteration of the population structure and a survey of
Patella on all types of shore.
The range of Patella vulgata in S.W. Britain is limited
at the top of the shore principally by desiccation. The
penetration of sheltered conditions is determined by interaction
between the fucoids and the limpets, On exposed shores, the
lower limit is determined by competition between P. vulgata and P. aspera. There is no direct relationship between mean size
and population density (expressed as weight per occupied area).
P. vulgata is densest at the borders of the fucoid communities
on sheltered shores, at the lowest levels on moderately exposed
shores, and at the junction with the P. aspera populations on
exposed shores. P. vulgata prevents fucoids from establishing
communities on many rook surfaces, but where fucoids form dense
stands, P. vulgata is not able to settle or feed. Physical
factors do not directly limit the range of P. vulgata (except
at the top of the shore), although they mediate the competition
and interaction which decide the precise boundaries, Inside
each P. vulgata population the growth rate 3.8 limited by intraspecific
competition for the available food

No full textJoin Fr. Thomas Rosica, CSB for this Witness interview with Fr. Michael Patella, OSB, a Benedictine monk of Saint John\u27s Abbey in Collegeville, Minnesota and a professor of New Testament at the Saint John\u27s School of Theology-Seminary. Both Fr. Rosica and Fr. Patella grew up in the diocese of Rochester, New York, and both studied Scripture during their years of formation in Rome and Jerusalem. Over the past decade, Fr. Patella has played a key role overseeing the creation of the Saint John\u27s Bible, the first Benedictine-commissioned, hand-written, hand-illuminated Bible in 400 years

Eyes wide shut. Lo sguardo, lo schermo, il quadro
No full textA partire da Lacan e dalla distinzione dell'occhio dallo sguardo, il saggio propone una riflessione sullo sguardo che evidenzia come lo sguardo non sia una prerogativa
del soggetto ma qualcosa che proviene dall’esterno, dalle cose, che ci cattura e ci espone radicalmente all’altro. In questo senso lo sguardo sarebbe ciò che sta prima del momento della visione di un’immagine e ha a che fare con il desiderio, producendo il desiderio stesso di guardare. Confrontandosi poi con la riflessione di Slavoj Zizek, viene sottolineato il tema di uno sguardo di traverso (looking awry), e uno «sguardo attraverso» ("diafano", alla lettera), che si muove tra adesione e distanza, tra prossimità e distacco, che rispecchia in fondo la nostra stessa condizione esistenziale di essere, contemporaneamente, dentro e fuori, vicini e lontani (d)alle cose stesse
