The “new pathology” seen in fertility clinics is the blocked fallopian tube without palpable disease. The cornu is a common site of occlusion, and bilateral tubal implantation can be highly successful. A less common site of occlusion is the fimbrial end of the tube. Here the surgical technics includes temporary use of a hood to protect the newly opened oviduct. Corrective technics for both types of occlusion are described. 相似文献

Generally, the chief indication for exploratory abdominal surgery is an increasing amount of abdominal pain accompanied by loss of weight or changes in eating habits. Roentgenographic studies and clinical symptoms sometimes are misleading and result in erroneous diagnoses of abdominal conditions.Surgical exploration frequently reveals unsuspected diverticula, benign lesions simulating malignant ones, scirrhous carcinoma, ulcers, or various biliary disorders.Abdominal exploration is accompanied by minimal risk. In the author's experience, this procedure has revealed the presence of a lesion in 50 per cent of cases. 相似文献

Research is proving that the effects of various mediators and changes in microcirculation bring about the cellular and metabolic consequences recognized clinically as shock. In this article, the authors approach diagnosis and treatment of the different types of shock through evaluation of hemodynamic variables. They summarize underlying causes of shock, the signs of its progressive stages, and diagnostic studies needed to guide treatment decisions. 相似文献

Pelvic lesions which require surgical treatment are primarily inflammatory, neo-plastic or mechanical, or a combination of any of these types. Surgery is recommended for conditions such as certain benign ovarian tumors, hydrosalpinx, ectopic pregnancy, large uterine fibroids, etc. Surgery is not advisable in such conditions as corpus luteum cysts and acute salpingitis or postabortal inflammatory disease. 相似文献

影像技术评价冠状动脉粥样硬化的进展 总被引:1,自引:0,他引:1
传统上,冠心病(coronary artery disease;CAD)的发展为血管内膜处的粥样斑块逐渐生长的过程。事实上冠心病不是管腔而是管壁的疾病。近来,冠心病的影像学检测有了很大发展,尤其是血管内超声、电子束CT、多层螺旋CT和MRI等检查,可能成为21世纪心血管疾病医学影像技术的热点。下面就有关的进展作一综述。1 冠脉造影、定量冠脉造影和血管内超声 自冠脉造影(coronary angiography;CAG)问世以来,尤其是定量冠脉造影(quantitative coronary angiography;QCA),因能检测动脉病变、指导冠心病介入治疗和评价药 相似文献

Purpose of Review
Trochlear dysplasia is a well-described risk factor for patellar instability. Trochleoplasty has emerged as a procedure within the surgical armamentarium for patellar instability, yet its role is unclear. A variety of trochleoplasty procedures have emerged. The purpose of this review is to clarify indications for trochleoplasty, outline the technical steps involved in performing common trochleoplasties and report the published outcomes and potential complications of these procedures.Recent Findings
Patellar instability with severe trochlear dysplasia is the main indication for trochleoplasty. Three types of trochleoplasty have emerged: (1) lateral facet elevation; (2) sulcus deepening; and (3) recession wedge. Deepening and recession wedge trochleoplasties are the most commonly performed.Summary
Trochleoplasty is a surgical option for addressing patellar instability in patients with severe trochlear dysplasia. Deepening and recession wedge trochleoplasties that address Dejour B and D dysplastic trochleas are the most studied, with both short- and midterm outcomes reported. Long-term outcomes are lacking and comparative studies are needed.9.

Purpose
The purposes of this review are to describe the pathogenesis of mucormycosis and to address recent research advances in understanding the mechanisms of fungal invasion and dissemination.Methods
Studies and reviews published in the PubMed and ClinicalTrials.gov databases until December 2017 that explored or reported recent advances in the understanding of the pathogenesis of mucormycosis were reviewed.Findings
To cause disease, fungal spores need to evade the innate immune system and germinate, leading to angioinvasion and tissue destruction. Recent studies have found that Mucorales are able to downregulate several host defense mechanisms and have identified the specific receptors through which Mucorales attach to the endothelium, facilitating their endocytosis and subsequent angioinvasion. In addition, certain conditions found to act through various mechanisms and pathways in experimental and animal studies, such as hyperglycemia, elevated iron concentrations, and acidosis (particularly diabetic ketoacidosis), increase the virulence of the fungi and enhance their attachment to the endothelium, rendering patients with uncontrolled diabetes and patients with iron overload susceptible to mucormycosis. The role and various antifungal functions of platelets and natural killer cells are highlighted, and the potential contribution of alternative therapies, such as manipulating the innate immune host defenses with granulocyte transfusions or administration of growth factors and using the antifungal effects of calcineurin inhibitors, are presented. Finally, directions and possible implications for future research are provided.Implications
This article provides a comprehensive overview of research advances in the pathogenesis of infections caused by Mucorales and helps future studies develop effective treatment strategies and improve patient outcomes. 相似文献18.
