The Luque procedure was developed to correct the deformity without the need of bracing and maintaining that correction with growth. However many authors are disappointed by their results and the complications which appear in the management of infantile scoliosis with Luque trolley alone. Besides failed implants, pseudarthrosis, modest spinal growth and protuberant rods and wires, the major problem of the Luque Systems is the high incidence of loss of correction by postoperative rotation. Therefore a new application technique is recommended. A Standard posterior extraperiostal approach is chosen. Sublaminar titanium cables are passed at each level except the caudal lamina. Then the rods are precontoured in shape of the planed curve correction. We use a Iow profile titanium Instrumentation with 5.0 mm diameter rods and 4.2 mm pedicle screws. In contrast to the conventional use of two antiparallel "L"rods we recommend the use of one reversed BU"-rod securing the laminae with sublaminar titanium cables of the upper end vertebrae. For fixation of the Iower spine a dual-opening pedicle screw System is used. Using a holding forceps the distal rods are introduced and fixed into the side opening of the screws then secured by sublaminar wires. In addition both single rods are stabilized by a Iow profile cross link bar. This technique allows to correct pelvic obliquity and a stable anchorage of two screws reduces risk of postoperatively rotation or caudal rod slippage due to gravity forces.Schlüsselwörter: Luque-Trolley, Wirbelsäule, Deformität, operative Therapie Die operative Technik nach Luque-Trolley wurde zur Therapie von Wirbelsäulendeformitäten im Wachstumsalter entwickelt und soll eine Immobilisation im Korsett ersetzen. Einige Autoren berichten jedoch über enttäuschende Ergebnisse sowie erhöhte Komplikationsraten bei alleiniger operativer Therapie von Patienten mit infantiler Skoliose durch das Luque-Trolley-System. Neben Implantatbrüchen, Pseudarthrosen, Wachstumsverzögerungen und kutanhervorstehenden Implantatanteilen besteht das Hauptproblem dieses Korrektursystems in der hohen Inzidenz von Korrekturverlusten durch eine postoperativ stattfindende Rotation. Zur Vermeidung der genannten Komplikationen empfehlen die Autoren eine neue Technik. Über einen extraperiostalen, standardisierten posterioren Zugang werden zur Fixation der Einzelsegmente sublaminare Titankabel mit Ausnahme des kaudalen Wirbels eingebracht, die zur Fixierung des zur Korrektur entsprechend vorgebogenen Stabsystems dienen. Die Autoren empfehlen hierzu die Verwendung von 0.5 mm dicken Titanstäben sowie den Einsatz von 4,2-mm-Pedikelschrauben. Im Gegensatz zur konventionellen Anordnung zweier L-förmiger, antiparalleler Stäbe wird die Verwendung eines umgekehrt-Uförmigen Stabes empfohlen, dessen kraniales Ende durch Laminakabel gesichert wird. Die beiden zur Fixierung der distalen Bewegungssegmente eingesetzten parallelen Einzelstäbe werden hingegen durch ein dual-offenes Pedikelschraubensystem fixiert, mittels Konnektionsmodul miteinander verbund...

A study was performed to evaluate a new transcervical, Fallopian tube access system for use in falloposcopy procedures without the need for conventional hysteroscopy or uterine distension. Visualization was accomplished by the use of a 0.5 mm falloposcope which was delivered to the Fallopian tube by a new linear everting catheter. The linear everting catheter allows access to the Fallopian tube by means of a flexible, tubular rolling membrane which can safely negotiate the tortuous anatomy from the ostium to the ampulla. Concurrent laparoscopy was performed solely for supervision purposes and not for tubal manipulations in 13 Fallopian tube access procedures in 10 patients. The ostia were visualized in 12 cases and the Fallopian tube was accessed in all 12 without complications. As a precursor for future gamete and embryo transfer procedures, intra-tubal insemination was performed by visualizing the ostia, accessing the Fallopian tubes, and obtaining successful isthmic-ampullary, intra-luminal images.

The object of these experiments was to determine the effect of various dosages of theelin on human female castrates of different ages and varying length periods of castration. It was of particular interest to study the effect of this hormone on the subjective symptoms that accompany castration and on the involutionary changes that occur in the breasts and the genital tract following ovariectomy.Stockard and Papanicolaou1 described an exact method for following the estrual changes in the living guinea-pig by the vaginal smear. This method has been applied to the correlation of the estrual phenomena in the genital organs of the rat2 and the mouse.3 Allen and Doisy,4 employing ovarian follicle fluid from hogs, produced pubertas praecox in immature albino rats.The vagina of the immature rat is completely closed, its external third being a solid cord of cells. They found that the injection of the ovarian follicular hormone into immature rats, both normal and spayed, induced a sexually mature condition in the genital tract similar to that of an animal experiencing its first estrus. This was effected in from two to three days by from four to six injections of an active extract at an age as early as 26 days, or from twenty to fifty days before the usual time of the attainment of puberty. This work was later confirmed by Frank, Kingery and Gustafson.5Allen and Doisy ß also devised a simple method of testing the potency of the follicular hormone by inject¬ ing a potent extract into spayed rats in which there was atrophy of the vaginal epithelium with the produc¬ tion of the estrous cycle on the third day. Frank T has demonstrated that an analogous potent hormone can be obtained from the follicles, the corpus luteum, the placenta and the blood of pregnant women.Allen, Pratt and Doisy 8 determined quantitatively the ovarian follicular hormone in the follicle, corpus luteum and placenta of the human female and of some animals, including the cow and the pig.Zondek and Aschheim, in 1927, found that the urine of pregnant women contains large quantities of the follicular hormone. Doisy,9 using such urine, was able to isolate the follicular hormone in crystalline form. This substance, like other isolated hormones, is of great potency.
