Assessment of late on-set fetal growth restriction using SMI (superb microvascular imaging) Doppler.

Background: The identification of late-onset fetal growth restriction (FGR) fetuses remains a challenge, given the difficulty to distinguish them from healthy small for gestational age (SGA) fetuses. Given the limitations of conventional Doppler for the identification of placental insufficiency, the appearance of superb microvascular imaging (SMI) Doppler seems promising. Our main objective was to evaluate the diagnostic capability of SMI Doppler for the detection of placental insufficiency findings.

Is It Possible to Diagnose Surgical Uterine Prolapse With Transperineal Ultrasound? Multicenter Validation of Diagnostic Software.

Objectives: To validate an ultrasound software that uses transperineal ultrasound to diagnose uterine prolapse (UP).

Methods: Multicenter, observational and prospective study with 155 patients that had indications for surgical intervention for dysfunctional pelvic floor pathology. Each patient underwent an examination with Pozzi tenaculum forceps was performed in the operating room with the patient anesthetized, followed by surgical correction of stages II-IV UP.

Transvaginal ultrasonography predictive model for the detection of pelvic congestion syndrome.

Background: The diagnosis of pelvic congestion syndrome (PCS) remains a challenge given the lack of universally accepted criteria. Although venography (VG) is the current gold standard for the diagnosis of PCS, non-invasive techniques like transvaginal ultrasonography (TVU) appear to be a valid alternative. The aim of this study was to design a predictive model for the venographic diagnostic of PCS using the parameters identified by TVU in patients with clinical suspicion of PCS, in order to individually assess the need to perform an invasive diagnostic and therapeutic technique such as VG.

Identification of Surgical Uterine Prolapse in Premenopausal Patients With Clinical or Ultrasound Criteria? A Multicenter Comparative Study.

Objectives: It is unknown whether diagnosing uterine prolapse (UP) via ultrasound or surgical criteria is superior. Our objective is to determine whether the diagnostic capacity of ultrasound with surgical criteria differs from that of surgical criteria only.

Methods: This was a multicenter prospective observational study with 54 premenopausal patients with surgical criteria for a dysfunctional pelvic floor pathology who were consecutively recruited for 1 year.

Reproducibility of the anorectal angle with transperineal ultrasound.

Background: The anorectal angle (ARA) has been assessed with different imaging methods and its measurement has traditionally been based on defecography or magnetic resonance studies. Different ultrasound methodologies have also been used for ARA assessment and have been validated as alternatives for the ARA measurement, such as three-dimensional (3D) endovaginal ultrasound and 3D transperineal ultrasound. 3D transperineal ultrasound does not require the introduction of ultrasound transducers inside the anal canal.

Can Intrapartum Ultrasonography Improve the Placement of the Vacuum Cup in Operative Vaginal Deliveries?

Although the fetal head position has traditionally been evaluated by digital examination (DE), it has a failure rate ranging between 20 and 70%; hence, intrapartum transabdominal ultrasonography (TUS) has become relevant. We aimed to evaluate the utility of the TUS to identify the fetal head positions in vacuum-assisted deliveries. We performed a prospective observational study including 101 pregnant patients in active labor who required a vacuum-assisted delivery.

Are Transperineal Ultrasound Parameters Useful to Predict Incontinence in Patients with Single-Incision Mini-Slings?

It would be logical to think that single-incision mini-slings (SIMS) should behave like the rest of the tension-free vaginal tape and, therefore, to believe that they present a similar ultrasound appearance, but there are no studies on this matter. Therefore, the main aim of our research is to determine which ultrasound parameters are associated with stress urinary incontinence (SUI) in patients carrying SIMS. A prospective observational study was carried out including 94 patients who were candidates for SUI corrective surgery with SIMS between 1 January 2021 to 31 December 2021 at the Universitary Hospital of Valme (Seville, Spain).

Monitoring of metals and metalloids from maternal and cord blood samples in a population from Seville (Spain).

Nowadays there is an increasing concern about exposition during prenatal stage to environmental pollutants such as metals, that make pregnant women a vulnerable group of population. Numerous studies have shown associations between the prenatal exposition to some metals and an impact on cognitive, motor and intellectual development of the child. Metals and metalloid are ubiquitous in the environment and pregnant women are exposed to them though their diet, lifestyle factors or occupational and environmental sources.

Can clinicopathological factors improve the prediction of metastasis to nonsentinel lymph nodes in patients with breast cancer?

Introduction: To determine whether clinicopathological characteristics can improve the prediction of metastasis to nonsentinel lymph nodes (NSLNs) over the use of only mRNA copy number in sentinel lymph node (SLN) biopsies.

Methods: This was a retrospective, observational study that included a total of 824 patients with T1-3 breast cancer who had clinically negative, ultrasound-negative axilla without evidence of metastasis and who underwent one-step nucleic acid amplification in SLN biopsies.

Results: 118 required a complete axillary lymph node dissection (ALNhD).

Predictive Model for the Diagnosis of Uterine Prolapse Based on Transperineal Ultrasound.

We want to describe a model that allows the use of transperineal ultrasound to define the probability of experiencing uterine prolapse (UP). This was a prospective observational study involving 107 patients with UP or cervical elongation (CE) without UP. The ultrasound study was performed using transperineal ultrasound and evaluated the differences in the pubis−uterine fundus distance at rest and with the Valsalva maneuver.

The Role of Transperineal Ultrasound for the Assessment of the Anorectal Angle and Its Relationship with Levator Ani Muscle Avulsion.

The relationship between the anorectal angle (ARA) and the levator ani muscle (LAM) is well known. In this study, we aimed to demonstrate that the ARA changes when LAM avulsion occurs after vaginal delivery. This was a secondary, observational retrospective study with data obtained from three previous studies.

Multicenter study of the evolution of different types of avulsion over the 12 months after delivery.

Objective: To perform a multicenter study of muscle recovery in levator ani muscle (LAM) avulsion during the first 12 months postpartum according to the type of LAM avulsion suffered.

Methods: This was a multicenter prospective observational study including 242 primiparas. Transperineal ultrasound was performed at 6 months and 12 months after delivery.

Quantification of 3/4D ultrasound pelvic floor changes induced by postpartum muscle training in patients with levator ani muscle avulsion: a parallel randomized controlled trial.

Background: We believe that physiotherapy with muscle training (MT) of the postpartum pelvic floor may lead to a change in the clinical management of patients with avulsion of the puborectal portion of the levator ani muscle (LAM). Our objective is to assess whether physiotherapy with MT of the postpartum pelvic floor in patients with LAM avulsion produces changes in pelvic floor morphology evaluated by 3/4D transperineal ultrasound.

Methods: This parallel randomized controlled trial (RCT) included 97 primiparous patients.

In Vitro Study of Preload Loss in Different Implant Abutment Connection Designs.

The stability and integrity of the abutment-implant connection, by means of a screw, is fallible from the moment the prosthetic elements are joined and is dependent on the applied preload, wear of the components and function. One of the main causes of screw loosening is the loss of preload. The loosening of the screw-abutment can cause complications such as screw fracture, marginal gap, peri-implantitis, bacterial microleakage, loosening of the crown and discomfort of the patient.

2D ultrasound diagnosis of middle compartment prolapse: a multicenter study.

Background: Recently, a specific methodology has been defined, using transperineal ultrasound, for the differential diagnosis of middle compartment prolapse [uterine prolapse (UP) or cervical elongation (CE) without UP] based on the difference in the pubis-uterine fundus distance at rest and with the Valsalva maneuver, with a cutoff point of 15 mm. The objective of this study was to validate the diagnostic utility of a ≥15 mm difference between the pubis-uterine fundus distance at rest and during the Valsalva maneuver to define UP in a multicenter study.

Methods: This prospective multicenter observational study included 94 patients (UP =51; CE without UP =43).

Identification of Pelvic Congestion Syndrome Using Transvaginal Ultrasonography. A Useful Tool.

The gold standard for the diagnosis of pelvic congestion syndrome (PCS) is venography (VG), although transvaginal ultrasound (TVU) might be a noninvasive, nonionizing alternative. Our aim is to determine whether TVU is an accurate and comparable diagnostic tool for PCS. An observational prospective study including 67 patients was carried out.

Interobserver variability of ultrasound measurements for the differential diagnosis of uterine prolapse and cervical elongation without uterine prolapse.

Objectives: Our study aims to determine the interobserver variability of different ultrasound measurements (pubis-cervix distance, pubis-uterine fundus distance, and pubis-Douglascul-de-sac distance) previously analyzed for the ultrasound differential diagnosis of uterine prolapse (UP) and cervical elongation CE without UP.

Materials And Methods: We conducted a prospective observational study with 40 patients scheduled to undergo surgical correction of UP and CE without UP. All patients underwent pelvic floor ultrasound examination by an examiner (E1) who acquired ultrasound images.

Evaluation of Pre-malignant Lesions of the Uterine Cervix by Shear Wave Elastography: A New Diagnostic Tool.

The objective of the study was to evaluate the difference in the stiffness between a healthy cervix (no pre-invasive lesions [NPILs]) and a cervix with a pre-invasive lesion (PIL). In the PIL group, we determined whether there was a difference in stiffness between the cervix with persistent low-grade lesions (>2 y, LSIL-persistent) and that with high-grade lesions (HSILs). Evaluation was performed using 2-D shear-wave elastography (SWE) in the midsagittal-plane of the uterine cervix (UC) at 0.

Severity and duration of allergic conjunctivitis: are they associated with severity and duration of allergic rhinitis and asthma?

The association of allergic conjunctivitis (AC) with rhinitis and/or asthma is poorly understood. The objective of this study was to apply the Consensus Document for Allergic Conjunctivitis (DECA) criteria for the classification of AC to a population of patients with AC to assess the association between the severity and duration of AC and rhinitis and/or asthma. Patients with ocular symptoms of AC who participated in the 'Alergológica 2015' study were included.

Objective: To determine the quality of life of spinal cord injuries with more than 10 years of evolution. Assess the prevalence of secondary complications, and their relationship with quality of life and time since the injury.

Patients And Method Design: Cross-sectional epidemiological study.

Adverse Health Effects in Women Farmers Indirectly Exposed to Pesticides.

Farmers are among the most vulnerable populations because of the exposure to low levels of pesticides. Acetylcholinesterase and butyrylcholinesterase activities are considered as biomarkers of pesticides poisoning. However, biomarkers of oxidative stress are also playing an important role in toxicity of these contaminants.

Complications in the Use of Deepithelialized Free Gingival Graft vs. Connective Tissue Graft: A One-Year Randomized Clinical Trial.

In the treatment of gingival recession, different surgical options have been described: free gingival grafts (FGG), connective tissue Grafts (CTG), and a more recent technique, de-epithelialized free gingival graft (DFGG). They are not procedures exempt from the appearance of complications. Most publications refer to postoperative complications, and there is limited literature regarding the development of late complications (weeks or months).

Height difference between the vestibular and palatal walls and palatal width: a cone beam computed tomography approach.

Background: The objective of this study was to measure two parameters involved in tri-dimensional implant planning: the position of the buccal and palatal bone wall and the palatal thickness.

Methods: Cone beam computed tomography (CBCT) images (Planmeca ProMax 3D) of 403 teeth (208 upper teeth and 195 lower teeth) were obtained from 49 patients referred to the Dental School of Seville from January to December 2014. The height difference between the palatal and buccal walls was measured on the most coronal point of both walls.

Evaluation of Placental Micro-vascularization by Superb Micro-vascular Imaging Doppler in Cases of Intra-uterine Growth Restriction: A First Step.

Superb micro-vascular imaging (SMI) Doppler has proven to be a valid method to assess normal placental micro-vascularization. In this study, we present the application of SMI Doppler to assess placental micro-vascularization in cases of placental insufficiency. We observed fewer secondary and tertiary villi in cases of intra-uterine growth restriction, as well as a lower pulsatile index of secondary villi.

A Radiographic and Clinical Comparison of Immediate vs. Early Loading (4 Weeks) of Implants with a New Thermo-Chemically Treated Surface: A Randomized Clinical Trial.

Implant dentistry has evolved over time, resulting in better treatment outcomes for both patients and clinicians. The aim of this trial was to test whether the immediate loading of implants with a platform-switching design influences the marginal bone level, compared to four-week loading, after one year of follow-up. Moreover, a comparison of clinical data regarding implant survival, implant stability, and patient-reported outcome measures (PROMs) was conducted.
