Combination high dose rate brachytherapy (HDRB) and external beam radiation therapy is technically and clinically feasible as definitive treatment for localized prostate cancer. We report the first large Australian experience using this technique of radiation dose escalation in 82 patients with intermediate‐ and high‐risk disease. With a median follow up of 3 years (156 weeks), complications were low and overall prostate‐specific antigen progression‐free survival was 91% using the American Society for Therapeutic Radiology and Oncology consensus definition. The delivery of hypofractionated radiation through the HDRB component shortens overall treatment time and is both biologically and logistically advantageous. As a radiation boost strategy, HDRB is easy to learn and could be introduced into most facilities with brachytherapy capability. 相似文献

Absence of the vagina occurs most frequently in the Rokitansky-Küster-Mayer (RKM) syndrome. Since Küster has reviewed the literature in 1910 many techniques have been described to create a neovagina. We describe a technique in which both a part of the labia minora and of the perineal skin are used as flaps to cover the neovagina and report on the long-term outcome in a series of 16 patients with RKM syndrome treated with this technique. No intra-operative or immediate postoperative complications were recorded. The average depth of the neovagina was 8 cm, at the end of the operation and 1 year later. After 3 months the neovagina was completely lined with vaginal epithelium. In six out of 16 patients scar formation and polypoid formation was observed at the apex of the neovagina. This could be successfully handled by excision and coagulation in all six cases. Ten patients reported a satisfactory sexual life. The technique is simple and easy to perform. The anatomical result and sexual gratification was outstanding in two-thirds of the patients. We conclude that flaps derived from the genital region offer the most physiological tissue for construction of a neovagina. 相似文献

Purpose:
A matched case–control study of all pregnancies obtained after either IVF or ICSI was conducted to investigate the perinatal outcome.
Methods:
Three hundred eleven singleton and 115 twin pregnancies obtained after assisted reproduction were studied. Controls were selected from a regional register and were matched for maternal age, parity, singleton or twin pregnancy, and date of delivery.
Results:
No significant difference was observed for gestational age at delivery, birth weight, incidence of congenital anomalies, and incidence of perinatal mortality between ART (singleton and twin) pregnancies and spontaneous controls. ART twin pregnancies showed a higher incidence of preterm deliveries than control pregnancies (52 vs 42%; P < 0.05) and needed more neonatal intensive care (47 vs 26%; P < 0.05).
Conclusions:
From this case–control study it is concluded that the perinatal outcome of ART singleton pregnancies is not different from that in matched controls. ART twin pregnancies showed a higher incidence of preterm deliveries than control pregnancies and needed more neonatal intensive care. 相似文献

Preconditioning with short cycles improves ischemic tolerance in rat fast- and slow-twitch skeletal muscle 总被引:1,自引:0,他引:1

AIM: The aim of this study was to investigate whether the efficacy of ischemic preconditioning (IP) in rat skeletal muscle depends on the duration of the preconditioning cycles. METHODS: Rats were divided into four groups (n = 10 each). The right hindlimb of rats in group A were subjected to 2.5 h of tourniquet ischemia followed by 2 h of reperfusion (I-R). Thereafter, muscular function was analyzed in vitro and high-energy phosphates (HEP) were determined by HPLC. Before I-R, right hindlimbs of rats in groups B-D subjected to IP with three cycles each consisting of 2.5, 5 or 10 min of ischemia followed by reperfusion for the same duration. RESULTS: Postischemic function of the extensor muscle was significantly improved with all three preconditioning protocols. Postischemic function of the soleus muscle was only improved by IP with three cycles of 5 min of ischemia and 5 min of reperfusion. Postischemic HEP tissue levels were not influenced by IP. CONCLUSION: This study shows for the first time that IP increases ischemic tolerance not only of fast-twitch but also of slow-twitch skeletal muscle. The efficacy of IP seems to be less dependent on the duration of the single preconditioning cycle than on the number of cycles performed. Three cycles each of 2.5, 5 or 10 min ischemia and reperfusion significantly improved postischemic skeletal muscle function. Tissue levels of HEPs, however, were not influenced by IP indicating that preservation of HEPs does not play a major role in the effects of IP on rodent skeletal muscle. 相似文献

Tyrosinemia type I is an autosomal recessive inherited defect of tyrosine metabolism. The underlying cause is a defect of fumarylacetoacetate hydrolase. The disease affects the liver (acute liver failure, liver cirrhosis, hepatocellular cancer), the kidney (tubulopathy with hypophosphatemic rickets), and the peripheral nervous system (paresthesia, vegetative symptoms, progressive paralysis). Beside the hypertyrosinemia the diagnosis can be made on the basis of urinary excretion of a pathological metabolite of the tyrosine metabolism (succinylacetone). Therapeutic options are a regulated phenylalanine/tyrosine diet, a very effective drug therapy (NTBC) that has been available for several years, and in cases of acute liver failure or end-stage liver cirrhosis a liver transplantation. 相似文献

In monochorionic twin pregnancies, the risk of developing a twin to twin transfusion syndrome is between 15 and 20%. Using high-resolution ultrasound machines, sonographic images demonstrate the detailed features of placental development. The lambda sign was established for the diagnosis of dichorionic placenta and the T sign for monochorionic placenta at the end of the first trimester. Other sonographic findings of the twin to twin transfusion syndrome are monochorionicity, same sex, polyhydramnios, permanently filled bladder in the recipient, and oligo/anhydramnios of the donor with a slightly filled or empty bladder. Fetoscopic laser treatment has become an accepted procedure to coagulate the placental anastomoses. This development is supported by actual studies about psycho- and neuromotoric development in early childhood, which shows a lower rate of disabled children in the group receiving laser therapy in comparison to the group undergoing amnioreduction. Twin pregnancies complicated by twin to twin transfusion syndrome should be treated in specialized prenatal centers. 相似文献

Pathological auditory brainstem responses (lack of responses, elevated thresholds and perturbed waveforms) in combination with present otoacoustic emissions are typical audiometric findings in patients with a hearing impairment that particularly affects speech comprehension or complete deafness. This heterogenous group of disorders first described as “auditory neuropathy” includes dysfunction of peripheral synaptic coding of sound by inner hair cells (synaptopathy) and/or of the generation and propagation of action potentials in the auditory nerve (neuropathy). This joint statement provides prevailing background information as well as recommendations on diagnosis and treatment. The statement focuses on the handling in the german language area but also refers to current international statements. 相似文献

The objective was to compare the outcome of a combined total hysterectomy-vaginectomy-phalloplasty procedure vs. a vaginectomy-phalloplasty procedure in female-to-male (FTM) gender dysphoric individuals, and to report on a large series of vaginectomies in young women. This was a retrospective study and the setting was the Gender Team at Ghent University Hospital. One hundred and five consecutive cases of vaginectomy-phalloplasty with (one-stage) or without (two-stage) total hysterectomy between 1993 and 2003 were included in the study. Patient files of 69 one-stage and of 36 two-stage procedures were reviewed and analysed. Operation time, the need for transfusions, complications, repeated surgery and hospitalisation time were the main outcome measures. Patients were equally distributed over the study period of 10 years. Comparing the two groups, there was a greater need for transfusion in the group of patients undergoing the one-stage procedure. There was no difference in operation time, rate of major complications or hospitalisation time. One-stage sex reassignment surgery (SRS) in FTM transsexual individuals is associated with more blood loss. However, there is no difference in operative and postoperative complications. Vaginectomy seems to be a safe and relatively simple procedure in FTM transsexual patients. 相似文献

Minimally invasive diagnostic procedures for the breast under mammography, ultrasound, and magnetic resonance guidance have led to a higher specificity of imaging techniques and a decrease in open biopsy of the breast. The percutaneous approach is more cost and time effective and reduces morbidity compared with open biopsy. The “Step-3-guideline for early breast cancer detection in Germany” represents the first national guidelines for a nationwide, quality assured, early breast cancer detection program, including recommendations for minimally invasive breast diagnostics. Indications for ultrasound guided vacuum biopsy of the breast are summarized in the “Consensus on the use and technique of vacuum-assisted sonographic breast biopsy” by the Study Group on Minimally Invasive Breast Interventions (AG MiMi) of the German Society of Senology (DGS). 相似文献
