The Republic of Congo is facing a shortage of specialists and an unequal distribution of healthcare professionals between urban and rural areas, limiting access to diagnostic ultrasonography. Besides other issues this project aims at establishing the feasibility of remote training by live teleconsultation in obstetrical ultrasonography, as a mechanism to support isolated care by untrained staff. The project includes abdominal ultrasound testing for women during all stages of pregnancy. The first results have shown that the transmission of dynamic images, at a low cost internet connection, offers the possibility of distance training of peripheral health professionals, with the real-time remote support of gynecologists...

OBJECTIVE: Ultrasonography in obstetrics and gynaecology (OB/GYN) is a vital component of patient assessment, diagnosis, and management. Standards for Canadian obstetrician-gynecologists' ultrasound skills are limited and vague. The primary objective was to audit the current curriculum administered to Canadian OB/GYN residents. The secondary objective was to understand self-perceived competency of final-year residents in performing OB/GYN ultrasound. We also sought to identify perceived barriers to incorporation of ultrasound into practice...

PURPOSE: Although magnetic resonance imaging (MRI) represents the gold standard for image guided adaptive brachytherapy (IGABT) for cervical cancer, the majority of brachytherapy (BT) continues to be guided by computed tomography (CT). However, CT seems to overestimate the target-volume definition, and the potential of transrectal ultrasonography (TRUS) needs further evaluation. This prospective, comparative study aimed to evaluate CT-based target contouring with the incorporation of TRUS during BT...

Ultrasonography has gained popularity in recent years among anaesthesiologists and being used widely for regional blocks and central venous catheterization. Ultrasonography for neuraxial blocks was found beneficial especially for determining the correct needle insertion site and estimating the needle insertion depth of epidural space. In many recent studies, ultrasound guided epidural and spinal blocks have been evaluated among obstetric patients. Pre-procedural lumbar ultrasonography and real time ultrasound guidance for neuraxial blocks was the subject of these studies...

BACKGROUND: Portal hypertension in pregnancy is associated with elevated risk of variceal hemorrhage. Ectopic varices, those located outside the esophagus or stomach, are rare but have a high risk of associated maternal morbidity or mortality. CASE: A 31-year-old woman, gravida 2 para 0010, with cirrhosis and portal hypertension was found to have abdominal wall ectopic varices on third-trimester obstetric ultrasonography. Computed tomography angiography confirmed these findings...

BACKGROUND/AIMS: In clinical settings, the pulsatility index (PI) has become a widely used tool for monitoring obstetrics or other vascular diseases. It is based on the maximum Doppler shift waveform derived from ultrasonography. However, it remains unclear whether the PI levels are correctly predicted from the perfusion in mouse model of hindlimb ischemia. METHODS: To explore the relationship between PI and perfusion, we generated a unilateral hindlimb ischemia model in 8-week-old C57BL/6 male mice by ligation of the right common iliac artery and femoral artery...

This article in our series on point-of-care ultrasound (US) for the regional anesthesiologist and pain management specialist describes the emerging role of gastric ultrasonography. Although gastric US is a relatively new point-of-care US application in the perioperative setting, its relevance for the regional anesthesiologist and pain specialist is significant as our clinical practice often involves providing deep sedation without a secured airway. Given that pulmonary aspiration is a well-known cause of perioperative morbidity and mortality, the ability to evaluate for NPO (nil per os) status and risk stratify patients scheduled for anesthesia is a powerful skill set...

Purpose: Sacrococcygeal teratomas (SCT) can be detected in ultrasonography as early as in the first trimester. Currently, prenatal ultrasonography enables a thorough examination of tumors, but it is not always sufficient. The purpose of this study was to determine the most important features of SCTs in fetal magnetic resonance imaging and to confront them with postnatal computed tomography (CT). Case report: Between 2009 and 2013, 5 cases of sacrococcygeal teratomas were diagnosed in our hospital using fetal magnetic resonance imaging (3 female and 2 male infants)...

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder, representing the single most common endocrine-metabolic disorder in reproductive-aged women. Currently there are four recognized phenotypes of PCOS: 1) hyperandrogenism+oligo-anovulation+polycystic ovarian morphology; 2) hyperandrogenism+oligo-anovulation; 3) hyperandrogenism+polycystic ovarian morphology; and 4) oligo-anovulation+polycystic ovarian morphology, each with different long-term health and metabolic implications. Clinicians should clearly denote a patient's phenotype when making the diagnosis of PCOS...

PURPOSE: Disorders related to pelvic floor include urinary incontinence (UI), anal incontinence, pelvic organ prolapse, sexual dysfunction and pelvic pain. Because pelvic floor dysfunctions (PFD) can be diagnosed clinically, imaging techniques serve as auxiliary tools for establishing an accurate diagnosis. The objective is to evaluate the PFD in primiparous women after vaginal delivery and the association between clinical examination and three-dimensional ultrasonography (3DUS). METHODS: A cross-sectional study was conducted in a in tertiary maternity...
