[Cervix and tocography screening in basic pregnancy monitoring].

Report about a myometrial contractility-screening in 2462 asymptomatic pregnancies at 30 weeks of gestation. A cervical examination was performed in the 26th and 33th weeks of gestation. An increased uterine contraction frequency was obtained in 3% and a cervical opening in 5.6%. Uterine contractions with cervical opening are a high-risk factor of prematurity (52%-70%) whereas uterine contractions alone are of low-risk. The prevention of preterm birth is useful. We found a significant decrease of early neonatal mortality in 487 singleton preterm deliveries after treatment. A classification of unexplained preterm delivery, iatrogenic or elective preterm delivery and complicated preterm labor is recommended for controlled outpatient and clinical trials.

[Pneumothorax after mediastinal emphysema. The site and mechanism of pleural rupture].

By rupture of the mediastinal pleura a mediastinal emphysema may lead to a pneumothorax. An experiment imitating this process is able to point out two spots where the pleura is most likely to tear: An area as large as a thumb tip above the root of the left lung; there mediastinal pleura covers a space the width of which changes most in respirating. The border of a fatty fold based on the pericardium and covered by mediastinal pleura; it is there that maxima of tension occur by emphysematic inflation. In general, air from the mediastinum far more often enters the left pleural cavity than the right one.

[The geometry of the human trochlea tali].

The geometrical shape of the trochlea tali is responsible for two completely different courses of motion in the ankle joint setting out from the neutral position: dorsiflexion and plantar flexion. Dorsiflexion: The tibia leads the talus, whereas the fibula is pushed laterally by the screw-shaped lateral articular facet of the talus. The malleoli tightly embrace the trochlea tali, whilst an obvious cleft appears dorsally and medially between the superior articular surface of the talus and the tibial roof. Plantar flexion: The fibula leads the talus which withdraws from the medial malleolus by stretching the anterior talofibular ligament. At the same time the superior articular face of the talus closely contacts the tibial roof.

[Accessory peroneal nerves in the human].

The Nervus peroneus profundus accessorius was described by Ruge (1878) in the lower mammals and for the first time identified by Bryce (1897) in man. It is an accessory terminal branch of the superficial peroneal (musculocutaneous) nerve which winds round the lateral malleolus beneath the tendons of the peronei muscles and reaches the dorsum of the foot; there it often supplies the lateral portion of the extensor digitorum brevis muscle. In further investigations this nerve has been traced in 21.2% of subjects resp. in 13.5% of legs. This nerve, however, is not the only accessory branch of the common peroneal nerve: In 14 out of 140 subjects (10%) resp. in 22 out of 280 legs (7.9%) a Nervus peroneus superficialis accessorius has been found. This nerve pierces the anterior crural intermuscular septum either in common with deep peroneal (anterior tibial) nerve or at a lower point. Then it descends in front of the septum rarely giving off muscular branches to the extensor digitorum longus and peroneus tertius muscles; in the lower half of the leg it pierces the crural fascia, passes in front of the ankle joint and becomes the medial cutaneous nerve of the dorsum of the foot. This accessory superficial peroneal nerve may be of importance in surgery of the leg and foot.

[Respiration-dependent shift in the region of the aortic arch].

The contents of the mediastinum take part in a different degree in its inspiratory longitudinal expansion: Heart, pulmonary root, and the bifurcation of the trachea--all of them connected with the diaphragm by pericardium or membrana bronchopericardiaca--move caudad proportional to the sinking of the diaphragm. Compared with the corona cordis the planum cardiacum moves further caudad according to its distance from the upper apertura thoracis. So the heart necessarily has to compensate for this difference by taking an upright position and by rotation to the right. The arcus aortae, however, fixed in the neck by its three main branches cannot perform such a proportional excursion. A significant distance of the left pulmonary root from the aortic arch is the result. At the same time a subaortal space, the 'spatium subaortale mediastini', unfolds into which a bulge of the pleura mediastinalis moves. This bulge is filled with tissue of the upper lobe of the left lung.

[Compensatory and stabilizing motions of the fibula].

There are two reasons why the fibula shows longitudinal motions. During dorsiflexion the push of the wedge-shaped trochlea tali causes an upward fibular motion; on the other hand, during weight bearing the contraction of the leg muscles effects a downward fibular motion. The specific level of the fibula results from these two correlating forces. While the upward fibular migration is a passive compensative movement, the downward fibular migration is an active stabilizing movement.

[Pyelorenal reflux. I. Actual and presumed routes].

An acute increasing pressure in the renal pelvis effects the phenomenon of pyelo-renal backflow. There is a confusing number of ways of the pyelo-renal backflow described so far, yet only few types of these ways can be verified by various and detailed investigations. 1. The pyelo-tubulous backflow (ptR) is a true backflow of the contents of the renal pelvis into the tubuli of the kidney. In no case tubuli rupture, because other ways of backflow are preferred instead of. 2. The pyelo-sinous extravasation (SE) is an outflow of the contents of the pelvis into the renal sinus owing to a rupture of the fornix. Starting from the ruptured fornix a descending extravasation spreads out between the pelvic wall and the adipose tissue in renal sinus, whereas an ascending extravasation spreads out between the flank of the pyramid and the adipose tissue. Horn-like arched ascending extravasations have been mistaken frequently for a backflow into the arcuate veins or even into their perivenous spaces. 3. The pyelo-venous backflow (pvR) is a transflow of the contents of the pelvis into an interlobar vein ruptured jointly with the fornix. 4. The pyelo-lymphatic backflow (plR) is a transport of the extravasation via lymph vessels. There can be a single way of backflow as well as divers combinations of the above mentioned types.
