Acute abdomen in obstetrics and gynecology is a common disease in clinical emergency, most of the patients have the characteristics of complex condition and rapid progress, and need to be treated through clinical diagnosis. There are many traditional diagnosis methods, but the accuracy is not ideal. Ultrasound is a widely used imaging technique in recent years, which has the characteristics of simple operation and high accuracy, so it is favored by doctors and patients in obstetrics and gynecology. In this study, 200 patients with acute abdomen in obstetrics and gynecology were selected, and the results of pathological examination were taken as the gold standard to evaluate the clinical value of ultrasound examination. As a result, the misdiagnosed ultrasound group was significantly lower after the diagnosis than in the normal group, the difference was significant (P > 0.05). Therefore, the use of ultrasound imaging, the clinical diagnosis of acute abdominal diseases in gynecology and obstetrics achieves a clear diagnostic effect, improves the diagnostic accuracy of patients with acute abdominal disease in the clinical. It is very important for the development of targeted therapeutic programmes.

Abstract Background and Aims Contrast-enhanced ultrasonography (CEUS) is a minimally invasive diagnostic tool available for diagnosing microvascular disturbances in tumors and many vascular pathologies. Unlike other radiological contrast agents, it is completely harmless for CKD patients and therefore it is used for the safe diagnosis of many diffuse or focal pathologies. Method We used CEUS examination in 50 CKD patients for the following pathologies: 10 atypical cysts, 15 liver focal lesions, 2 splenic focal lesions, 3 renal infarcts, 12 kidney focal lesions and 8 other organ involvements. Examination was made using a VOLUSON E8 machine (GE Medical System Kreztechnik GmbH Tiefenbach 15, Austria) with a 3.5 MHz convex array abdominal transducer. 2.4 ml of microbubble contrast-agent was administered intravenously and recording of the results were made for 3-5 minutes after injection. Results Depending on the organ vascular characteristics, contrast enhancement and/or wash-out were suggestive for the final diagnosis. In liver lesions there are three phases and in kidneys, spleen, gallbladder, adenopathies there are two vascular phases. We obtained a very good positive predictive value and sensitivity in detecting malignant lesions. Conclusion According to The EFSUMB Guidelines and Recommendations for the Clinical Practice of Contrast-Enhanced Ultrasound they are used both for hepatic and Non-Hepatic Applications. Being non-invasive and non-irradiating it could be the main diagnostic examination in CKD population in the future.

Porous tantalum (Ta) is a promising biomaterial and has been applied in orthopedics and dentistry for nearly two decades. The high porosity and interconnected pore structure of porous Ta promise fine bone ingrowth and new bone formation within the inner space, which further guarantee rapid osteointegration and bone-implant stability in long term. Porous Ta has high wettability and surface energy that can facilitate adherence, proliferation and mineralization of osteoblasts. Meanwhile, low elastic modulus and high friction coefficient of porous Ta can effectively avoid stress shield effect, minimize marginal bone loss and ensure primary stability. Accordingly, the satisfactory clinical application of porous Ta based implants or prostheses are mainly derived from its excellent biological and mechanical properties. With the advent of additive manufacturing, personalized porous Ta based implants or prostheses have shown their clinical value in the treatment of individual patient who need specially designed implant or prosthesis. In addition, many modification methods have been introduced to enhance the bioactivity and antibacterial property of porous Ta with promising in vitro and in vivo research results. In any case, choosing suitable patients is of great importance to guarantee surgical success after porous Ta insertion.

SummaryTympanic plethysmography is a simple non-invasive diagnostic technique which is used to differentiate between intra-temporal carotid aneurysms and glomus jugulare tumours and to predict the degree of extension of the tumour. It is performed by the indirect recording of volume pressure changes of pulsating tympanic masses using a pressure transducer. The volume pressure change of the pulsating mass is transmitted to the pressure transducer through a saline-filled system.Medical technology has undergone considerable progress with the introduction of new techniques in medical diagnosis less harmful to the patient and with a reduced risk of complications. The collaboration of doctors, scientists and bioengineers has resulted in the evolution of such changes, thereby trying to replace the more aggressive or invasive diagnostic techniques. The ideal diagnostic technology is one without pain, harm or complications to the patient.Medical diagnostic technology may be classified as invasive or noninvasive. Non-invasive diagnostic technology is either active, using an external source of energy such as ultrasound (ultrasonography) or a small dose of X-rays, as in computerized axial tomography; or passive, using the energy emitted by human structures, as in plethysmography.Plethysmography is the recording of volume pressure changes. Oculoplethysmography is used to monitor extracranial occlusive carotid disease (Kartchner and McRae, 1973). The use of sound energy as an internal energy emitted by the human body has proved effective as a passive, non-invasive diagnostic technique (Tewfik, 1976, 1977).Volume pressure changes of intra-temporal carotid aneurysms have been recorded, using a pressure transducer (Tewfik, 1974).In this article the volume pressure changes of glomus jugulare tumours have been recorded and the findings compared with those obtained, and previously published, for intra-temporal carotid aneurysms. Volume pressure changes of pulsating tympanic masses may be called tympanic plethysmography. A trial of this simple non-invasive diagnostic technique for differentiating pulsating tympanic masses is here reported, together with an assessment of the technique in its ability to predict the degree of extension of glomus jugulare tumours.

Common types of gynecological acute abdomen include ovarian cyst pedicle torsion, ectopic pregnancy, luteal rupture, and acute pelvic inflammatory disease. Make accurate diagnosis and surgical treatment of acute abdomen patients in obstetrics and gynecology in time, otherwise it will cause life danger or loss of organ function, therefore, accurate and timely diagnosis and treatment of gynecological acute abdomen is very important for the prognosis of patients. Ultrasound imaging has important clinical value for the diagnosis of acute abdomen in obstetrics and gynecology. Ultrasound imaging has the advantages of simple examination, rapid reporting, and no pain in the subject, which is one of the best methods for diagnosing acute abdomen in obstetrics and gynecology. This study analysed and summarized the imaging principles of ultrasound imaging in acute obstetrics and gynecology and the imaging characteristics of various acute abdomen. A retrospective analysis of patients with acute obstetrics and gynaecology performed in our hospital from December 2017 to June 2019 was performed. The diagnostic analysis of ultrasound imaging in acute obstetrics and gynaecology was performed. The results showed that the ultrasound imaging diagnosis results of 202 obstetric and gynecological acute abdomen patients were compared with the results of surgery and pathological diagnosis. Among the 182 cases with correct ultrasound imaging diagnosis, the coincidence rate was 90.1%, and 20 cases were misdiagnosed, accounting for 9.9%. The research of this study shows that the ultrasound examination technique for patients with acute obstetrics and gynaecology is simple, fast, non-invasive, and has high accuracy. Ultrasound imaging can provide reliable objective evidence for the diagnosis and differential diagnosis of most acute abdominal diseases, in order to improve the diagnosis rate and reduce the misdiagnosis rate.

Abstract Background: Low-dose alteplase (LrtPA) has been shown not to be inferior to the standard-dose (SrtPA) with respect to death/disability. Objective: We aim to evaluate the percentage of patients treated with LrtPA at our center after the ENCHANTED trial and the factors associated with the use of this dosage. Methods: Prospective study in consecutive patients with an acute stroke admitted between June 2016 and November 2018. Results: 160 patients were treated with intravenous thrombolysis, 50% female; mean age 65.4±18.5 years. Of these, 48 patients (30%) received LrtPA. In univariate analysis, LrtPA was associated with patient's age (p=0.000), previous modified Rankin scale scores (mRS) (p<0.000), hypertension (p=0.076), diabetes mellitus (p=0.021), hypercholesterolemia (p=0.19), smoking (p=0.06), atrial fibrillation (p=0.10), history of coronary artery disease (p=0.06), previous treatment with antiplatelet agents (p<0.000), admission International Normalized Ratio-INR (p=0.18), platelet count (p=0.045), leukoaraiosis on neuroimaging (p<0.003), contraindications for thrombolytic treatment (p=0.000) and endovascular treatment (p=0.027). Previous relevant bleedings were determinants for treatment with LrtPA. Final diagnosis on discharge of stroke mimic was significant (p=0.02) for treatment with SrtPA. In multivariate analysis, mRS (OR: 2.21; 95%CI 1.37‒14.19), previous antiplatelet therapy (OR: 11.41; 95%CI 3.98‒32.70), contraindications for thrombolysis (OR: 56.10; 95%CI 8.81‒357.80), leukoaraiosis (OR: 4.41; 95%CI 1.37‒14.10) and diagnosis of SM (OR: 0.22; 95%CI 0.10‒0.40) remained independently associated. Conclusions: Following the ENCHANTED trial, LrtPA was restricted to 30% of our patients. The criteria that clinicians apply are based mostly on clinical variables that may increase the risk of brain or systemic hemorrhage or exclude the patient from treatment with lytic drugs.
