Despite the extensive recent development of different techniques for endoscopic evaluation for both diagnostic and therapeutic reasons, the small bowel remains quite difficult to visualize. Capsule endoscopy and device assisted enteroscopy are presently considered the best diagnostic tools for examination of small bowel disorders, assessing diverse pathologies such as obscure gastrointestinal bleeding, iron deficiency anemia, Crohn disease, small bowel tumors and polyposis syndromes. Like any other imagistic method, it has specific indications, and contraindications, and possibly it is more important to consider limitations. In order to obtain a better result, it is necessary to respect the procedural quality indicators. Among them the use of prokinetics - diverse pharmacological substances increasing the success rate of capsule endoscopy have raised debates. Capsule endoscopy small bowel evaluation is a reliable, non-invasive and safe with many advantages and minimum risks, with a proper selection of patients, and can be used as first line investigation.Primary immune thrombocytopenia (ITP), formerly known as idiopathic thrombocytopenia, is defined by a reduced platelet count less then 50x109 and is clinically manifested through signs and symptoms such as bleeding, ecchymosis and petechiae. Its coexistence with the implantation of the mechanical valves and the necessity of anticoagulation creates an additional risk of bleeding. Although mechanical valves are indispensable in prolonging and improving the quality of life in patients with valvular heart disease, in the context of an additional bleeding risk factor, their presence could represent a threat to life exposing the patient to major complications and leading to death. The purpose of this case report is to discuss the disadvantages and possible fatal complications of the association between mechanical valves and severe thrombocytopenia. A possible solution to these downsides could be found in the future search in regenerative medicine and tissue engineering of heart valves resulting in products that do not require anticoagulation and do not pose a threat to patients with thrombocytopenia.The objective was to have a quantitative description of the normal position of the fetal midbrain in the first trimester, through defining the reference ranges for the mesencephalon to the occipital bone distance, in the axial plane. This was a prospective study that included normal fetuses screened between 11 and 13 weeks of gestation. The distance was measured between the posterior limit of the mesencephalon to the occipital bone in the same axial view as the one required for the biparietal diameter (BPD) assessment, at this gestational age (GA). learn more The reference ranges using quantile regression, according to the crown-rump length (CRL), BPD, and GA were fitted. Data analysis included 428 ultrasound measurements. A good, linear correlation was observed between mesencephalon to occiput (MO) distance and CRL, BPD, or GA. It increased linearly with advancing gestation (log10MO = -0.1834 + 0.0092 x CRL, R2=0.48, P less then 0.0001) and was independent of maternal demographic characteristics and intracranial translucency (IT). In our study, the 1st percentile of the normal MO distance varies from 1.31 mm at a CRL of 45 mm to 2.08 mm at a CRL of 84 mm. The intraclass correlation coefficient (ICC) was 0.89 for intraobserver variability. A significant increase in the MO distance was found in the patients who did not receive folic acid in the first trimester of pregnancy [1.056 vs. 1.008 multiple of median (MoM), P=0.014]. A simple measurement is described between the midbrain and the occipital bone, obtained in the same axial view. It increases linearly with advancing gestation. Integration of this measurement into the routine ultrasound screening in association with the 'crash sign' and recognizing the lower extreme values could lead to an early diagnosis of open spina bifida (OSB).Posterior fossa ultrasound appearance may offer clues for brain anomalies as early as the first trimester. The purpose of the study was to find an easy, reproducible method to examine the posterior fossa. From January 2017 to March 2018, 132 consecutive pregnancies presenting for first-trimester screening, were selected at 11-14 weeks' gestation. An oblique axial view of the fetal head was routinely achieved with visualization of the posterior fossa, wherein the cisterna magna (CM) and the fourth ventricle (V4) anteroposterior diameter was measured. Moreover, 81 patients had a follow-up scan at 19-24 weeks, and the CM and transverse cerebellar diameter (TCD) were measured. Normal ranges were established at 11-14 weeks for CM and V4 according to crown-rump length (CRL). The 50th centile for CM ranges from 1.2 mm to 2.3 mm at a CRL between 45 and 85 mm. The V4 50th centile ranges from 1.8 to 2.4 mm. A positive correlation was found between the first-trimester and second-trimester CM diameter and between the first-trimester V4 and second-trimester TCD. There is an inverse correlation between the first-trimester CM and second-trimester TCD. The measurements of different components of the posterior fossa in the first trimester cannot predict the size of CM and TCD in the second trimester. The presence of the three hypoechoic structures (cerebral peduncles, V4, and CM) separated by two hyperechoic lines is easy to see and measure.Modified laparoscopic transabdominal cerclage (LTAC) was developed as a safer approach for the treatment of cervical insufficiency in pregnancy, with the cerclage tape placed lateral to the uterine vessels. We describe and review the evolution of a woman who successfully underwent an LTAC at 12 weeks of gestation, whose fetus developed growth retardation after 32 weeks. Three-dimensional power Doppler reconstruction viewed both uterine arteries (UtAs) inside of the cerclage until the second trimester. Thereafter, the visualization of UtAs showed the development of a rich array of collateral vascularization, adaptation supported by the findings of low velocity and pulsatility of blood flow in the UtAs. The appearance of the UtAs varies throughout the gestation. There is a moderate variation of the shape and curvature that could result due to their elongation. Furthermore, the cervical length increased during gestation, from 20 to 30 mm. We speculate that this is a mechanical modeling during the late gestation.
