左室假腱索137例的临床分析

对1944例连续受检者,用超声心动图检测其假健素,在980例有器质性心血管病者中,发现左室假腱素68例、占6.93％(68/980);在964例无器质性心血管病者中,发现左室假腱素69例、占7.16％(69/964)。两组检出率无显著差异(X~2=0.03554,P>0.05)。对左室假腱素引起的心脏杂音和窒性心律失常的机制、临床特征和意义亦进行了讨论。

The Costello syndrome: Are nasal papillomata essential?

Summary Two patients with the Costello syndrome are presented. One was a 7-year-old girl with a history of infantile hypotonia and feeding difficulties. The other was a 3 5/12-year-old boy with a history of neonatal sepsis and respiratory problems. Both had relative macrocephaly at birth, curly hair, large ear lobes, epicanthic folds, a low nasal bridge, thick lips, a short and wide nose, a short neck, a barrel chest, redundant skin, tight Achilles tendons, and pes equinovarus. Nasal papillomata, as described in Costello's two patients, were absent in both patients. Borochowitzet al. (1992) described five patients with what we interpreted as the Costello syndrome but without nasal papillomata. In view of these findings, nasal papillomata are not likely to be essential in the diagnosis of the Costello syndrome.     

Reconstruction of the superior peroneal retinaculum using an autologous gracilis tendon graft for chronic dislocation of the peroneal tendons accompanied by lateral instability of the ankle: technical note

This is a technical note on reconstructive surgery for the combination of chronic dislocation of the peroneal tendons and lateral instability of the ankle. The traditional surgery for this condition consists of direct repairs of the lateral ligaments of the ankle and the superior peroneal retinaculum, if possible. However, repair surgery is difficult in cases with insufficient structural remnants. We describe here a technique of simultaneous reconstruction of the anterior talofibular ligament and superior peroneal retinaculum with an autologous gracilis tendon graft for the combination of chronic dislocation of the peroneal tendons and lateral instability of the ankle.     

Effects of training, immobilization and remobilization on tendons

Since a tendon is a living tissue, it is not a surprise that tendon shows the capacity to adapt its structure and mechanical properties to the functional demands of the entire muscle-tendon unit. However, compared with muscle, the experimental knowledge of the effects of strength or endurance-type training on tendon tissue is scarce and clinical human experiments are completely lacking (1). Research should, however, be able to improve the true understanding of the biomechanical, functional, morphological and biochemical changes that occur in tendons due to training and physical activity, since understanding of the basic physiology of a tissue is the key to understanding its pathological processes (1,2). Compared with muscle tissue, the metabolic turnover of tendon tissue is many times slower due to poorer vascularity and circulation (1, 3). The adaptive responses of tendons to training are therefore also slower than those in muscles, but they may finally be considerable if the time frame is long enough (3, 4).     

Primary repair of flexor tendons in the hand with early passive mobilization

Summary Flexor tendon injuries in zones I–III in the hand were treated by meticulous suture of the tendons and peritendinous structures, followed by early passive mobilization of the injured fingers, the remaining fingers being kept extended by a plaster splint. This method was used in 51 cut tendons in 38 patients. The functional recovery approached normal in 72%, and only 8% were poor.

Résumé La section traumatique des tendons fléchisseurs à la main au niveau des zones I à III a été traitée par suture minutieuse des tendons et des structures péri-tendineuses, suivies d'une mobilisation passive précoce des doigts atteints, tandis que les autres doigts étaient maintenus étendus par une attelle plâtrée. Cette méthode a été utilisée pour la réparation de 51 tendons chez 38 malades. La récupération d'une fonction quasi-normale a été obtenue dans 72% des cas, avec seulement 8% de mauvais résultats.

     

Age related Ca−Mg content and strength in turkey tendon

The age related variation in magnesium and calcium content and mechanical properties of turkey tendon from ages 9–14 weeks has been studied. The results show that magnesium content decreases with age during this period and calcium content remains essentially constant. This is in accord with a previously proposed mechanism of calcification, namely, that the local concentration of magnesium and calcium may be an important factor relating to the initiation of calcification in a given tissue. The tensile strength of the turkey tendon has been found to decrease with age during the precalcified period of 9–12 weeks, after which there is an increase in tensile strength coincident with the onset of calcification. The ultimate elongation decrease of approximately 4% between 9 and 13 weeks is attributed to the difference in extensibility of the “wavy” collagen fibers observed in uncalcified turkey tendonvis a vis the straight fiber bundles in turkey tendon specimens observed at the onset of calcification.
