RESUMO

Building inclinations can be measured through the use of ultrasonic hydrostatic levelers. These are used to measure long-term relative displacements of vertical parts of structures and utilize the principle of communicating vessels (similar to the classic water scales). The presented ultrasonic displacement measurement technique was developed by Ultrasystem in the 1990s and was applied to several objects in Poland. Long-term measurements enabled the development of a model of object behavior under the influence of various factors. Among these are the annual cycle of temperature changes, fluctuating water levels, turbine chamber emptying, etc. Such a model can facilitate the prediction of failure based on the appearance of changes deviating from typical behavior (e.g., a much stronger dependence of the inclination as a function of the water level). The results obtained with the help of ultrasonic sensors enable the observation of subtle deformations of the object, which is valuable when developing and calibrating new models of the object (e.g., by means of the finite element method).

RESUMO

BACKGROUND: Gynecological examination and transvaginal ultrasound are difficult or impossible in girls and young women who have not started their sexual life. CT is not a method of choice in this age group because of the ionizing radiation and iodine-containing contrast media. MRI is chosen then. MATERIAL/METHODS: Pelvic MRI was performed in 15 patients aged 9-19 years with suspected ovarian mass after they had had unclear gynecological and sonographic examinations. 1.5 T MRI systems were used. SE,T(F)SE and SPIR sequences were applied in T1- and T2-weighted images in three planes. Contrast media were administered in 7 patients. RESULTS: In a group of 3 girls with acute abdominal pain, polycystic ovaries, ovarian hemorrhagic cyst, and fibroma of the ovary were diagnosed. In a group of 11 patients with chronic abdominal pain, dermoid cysts of the ovaries were found in 7 cases, in one bilateral and accompanied by ectopic kidney. In 2 patients, serous cysts were diagnosed. In 2 cases an ovarian origin of the mass was excluded: multilocular cystic lesion in the presacral region and a hydatid mole were revealed. A neoplastic ovarian mass was diagnosed in a girl with increasing circumference of the abdomen. The accuracy of MRI in localizing lesions was 100%. Its accuracy in precisely characterizing lesions was 83.3%. CONCLUSIONS: Magnetic resonance imaging, with its noninvasiveness, high spatial resolution, and tissue specificity, is a method of choice in the diagnosis or exclusion of ovarian pathology in children and adolescents.

RESUMO

UNLABELLED: People with diabetes mellitus have higher risk of cardiovascular morbidity and mortality from thrombo-vascular complications than non-diabetics and it is recommended that they should use acetylsalicylic acid (ASA) as anitiplatelet agent regularly. The aim of this study was to examine current physician counseling about ASA therapy and the use of ASA by Polish patients with diabetes. The study involved 464 randomly selected Caucasian diabetic individuals, mainly with type 2 (>98%), who were asked to complete a questionnaire consisting of 16 questions while visiting out-patient medical centres for periodical examination or during hospitalization. We collected data on the prevalence of cardiovascular disease (CVD), frequency of risk factors among diabetic patients and on ASA physician counseling, and on the rate of regular ASA users among the patients. The most self-reported conditions were angina pectoris or prior myocardial infarction (63,6%). Current cigarette smoking was declared by 7,1% of the patients, elevated serum cholesterol levels by 58%, and hypertension by 62,9%. Majority of the patients were overweight, and family history of coronary artery disease (CAD) was reported by 30,2% of the patients. ASA was taken by 67,2% of all the patients and 72,1% of them had taken ASA regularly. The highest percentage (>80%) of regular ASA users was found among diabetic patients with CAD. A minority of the patients who reported stroke (43,9%) or claudication (15,8%) were taking ASA regularly. Number of the patients (32,8%) with CVD risk factor(s) but without diagnosed CVD did not use ASA at all. The majority of the patients (78%) were counseled by their physicians why they should use ASA regularly. IN CONCLUSION: the number of regular users of ASA among diabetic patients in Poland with CVD others than CAD or among patients with at least two CAD risk factors is still unsatisfactory. Therefore, while it seems that there is a remarkable growing of ASA therapy world-wide more effort is needed to make this practice a standard of multifactorial, intensive diabetes treatment. Our results also suggest the need for more aggressive education of both doctors and patients.

RESUMO

Until quite recently the diagnosis of cervical pregnancy was an indication for hysterectomy, because of mortality among patients with cervical pregnancy, coming up to 60%. During last 15 years methods of conservative therapy has developed in order to avoid the necessity of hysterectomy and to keep patient's fertility. Among these the most promising method is using of methotrexate (MTX), which is now the most commonly used agent in case of conservative forms for the treatment of cervical pregnancies. It should be stressed successful in treatment of cervical pregnancy in women, who wish to remain fertile, depends on early and proper diagnosis. MTX can be administered up to 13 weeks of gestation, with the highest efficacy between 6-8 weeks of pregnancy. We reported a case of cervical pregnancy treated successfully with methotrexate therapy combined with curettage of the cervical canal and uterine cavity. Serial beta HCG serum determination and ultrasonography were used to diagnose the pregnancy and to monitor therapy. Treatment was effective and the patient reproductive capability was preserved.
