Objectives: Evaluate diagnostic accuracy of median nerve cross‐sectional area (CSA) to determine severity versus presence of carpal tunnel syndrome (CTS) across existing electrodiagnostic‐based (EDX) classification systems in patients with type 2 diabetes or bifid anatomy. Methods: Retrospective analysis of cross‐sectional patient data. Receiver operating characteristic analysis used to determine median nerve CSA cutoff values and associated diagnostic likelihood ratios for all consolidated and binary EDX‐based classifications of CTS in patients with type 2 diabetes or bifid anatomy. Determine shifts in diagnostic probability based on established cutoff values and associated likelihood ratios. Distal CSA measured at or near carpal tunnel inlet, proximal CSA at level of pronator quadratus muscle, and delta CSA by subtracting proximal from distal. Results: Binary categorizations of CTS were statistically superior to consolidated categorizations of CTS severity in patients with type 2 diabetes or bifid anatomy. Binary categorizations established reasonably consistent median nerve CSA cutoff values across all EDX‐based classifications examined resulting in the following for distal CSA or delta CSA: ≤10 or ≤4 mm2 to rule out and ≥11 or ≥5 mm2 to rule in CTS, respectively. These cutoff values resulted in small shifts in diagnostic probability in patients with type 2 diabetes and small to conclusive shifts in diagnostic probability in patients with bifid anatomy. Conclusions: Binary categorizations to rule out or rule in CTS based on the proposed cutoff values provide the most meaningful information about shifts in diagnostic probability across all EDX‐based classifications examined. The use of median nerve CSA to categorize severity of CTS is not recommended in patients with type 2 diabetes or bifid anatomy. [ABSTRACT FROM AUTHOR]

Abstract Background Sonographic evaluation of the diaphragm has gained popularity in the ICU due to the necessity of assessing diaphragmatic function in a variety of clinical situations. The sonographic examination of diaphragmatic dynamics in ICU patients by measuring diaphragmatic thickness and excursion in connection to various modalities of mechanical ventilation (MV) and patient outcomes was the objective of this study. Methods This prospective observational study was carried out on 50 patients in respiratory ICU in Kafr Elsheikh and Benha University Hospitals. Patients were classified into 2 equal groups: COVID-19 group and non-COVID group. All patients underwent ultrasound assessment included the diaphragm thickness fraction and excursion in ICU patients on admission and on weaning. Results Successful weaning (SW) was higher in group I compared to group II. In group I (COVID), diaphragm excursion, thickness at end inspiration and at end expiration in NIV at weaning were significantly higher in patients with SW but thickness at end expiration on admission was significantly lower. In group II (non-COVID) MV patients, excursion at weaning was significantly higher in patients with SW, also were thickness at end inspiration and end expiration on admission, thickness at end inspiration and end expiration at weaning in NIV patients but thickness at end inspiration in MV on admission was significantly lower. Conclusion Weaning success and mortality were significantly predicted by excursion in NIV at weaning, thickness at end inspiration in MV at weaning, thickness at end inspiration in NIV at weaning, and thickness at end expiration in MV at weaning.

Adenomyosis is a benign uterine disorder where endometrial glands and stroma are pathologically demonstrated within the uterine myometrium. The pathogenesis involves sex steroid hormone abnormalities, inflammation, fibrosis and neuroangiogenesis, even though the proposed mechanisms are not fully understood, the different type and extension of adenomyosis detected by transvaginal ultrasound could be associated with clinical symptoms. The current study was designed with an aim to correlate between ultrasound finding in symptomatic patient with adenomyosis and severity of the disease. It was a cross sectional study conducted on 100 symptomatic women with sonographic criteria of adenomyosis recruited from the outpatient gynecology and obstetrics clinic after proper counseling, history taking and ultrasound examination to detect ultrasound criteria of adenomyosis and doppler on uterine artery done to all patients to detect uterine artery resistance index, pulsatillity index and Vmax. There is a relation between Tumor vascular pattern and abnormal uterine bleeding mainly and chronic pelvic pain. We found non-statistically significant differences between sonographic findings and symptoms among the studied population. [ABSTRACT FROM AUTHOR]

Purpose: Adenomyosis is a common disease of females during their reproductive age. As of today, histologic examination of the uterus after hysterectomy constitutes the gold standard for diagnosis. The aim of this study was to determine the validity of sonographic, hysteroscopic, and laparoscopic criteria for the diagnosis of the disease. Methods: This study included data collected from 50 women in the reproductive age of 18–45 years, who underwent a laparoscopic hysterectomy in the gynecology department of the Saarland University Hospital in Homburg between 2017 and 2018. The patients with adenomyosis were compared with a healthy control group. Results: We collected data of anamnesis, sonographic criteria, hysteroscopic criteria and laparoscopic criteria and compared it with the postoperative histological results. A total 25 patients were diagnosed with adenomyosis postoperatively. For each of these; at least three sonographic diagnostical criteria for adenomyosis were found compared with a maximum of two for the control group. Conclusion: This study demonstrated an association between pre- and intraoperative signs of adenomyosis. In this way, it shows a high diagnostic accuracy of the sonographic examination as a pre-operative diagnostic method of the adenomyosis. [ABSTRACT FROM AUTHOR]

Abstract Background It is challenging to predict the outcome of the pregnancy when fetal heart activity is detected in early pregnancy. However, an accurate prediction is of importance for obstetricians as it helps to provide appropriate consultancy and determine the frequency of ultrasound examinations. The purpose of this study was to investigate the role of the convolutional neural network (CNN) in the prediction of spontaneous miscarriage risk through the analysis of early ultrasound gestational sac images. Methods A total of 2196 ultrasound images from 1098 women with early singleton pregnancies of gestational age between 6 and 8 weeks were used for training a CNN for the prediction of the miscarriage in the retrospective study. The patients who had positive fetal cardiac activity on their first ultrasound but then experienced a miscarriage were enrolled. The control group was randomly selected in the same database from the fetuses confirmed to be normal during follow-up. Diagnostic performance of the algorithm was validated and tested in two separate test sets of 136 patients with 272 images, respectively. Performance in prediction of the miscarriage was compared between the CNN and the manual measurement of ultrasound characteristics in the prospective study. Results The accuracy of the predictive model was 80.32% and 78.1% in the retrospective and prospective study, respectively. The area under the receiver operating characteristic curve (AUC) for classification was 0.857 (95% confidence interval [CI], 0.793–0.922) in the retrospective study and 0.885 (95%CI, 0.846–0.925) in the prospective study, respectively. Correspondingly, the predictive power of the CNN was higher compared with manual ultrasound characteristics, for which the AUCs of the crown-rump length combined with fetal heart rate was 0.687 (95%CI, 0.587–0.775). Conclusions The CNN model showed high accuracy for predicting miscarriage through the analysis of early pregnancy ultrasound images and achieved better performance than that of manual measurement.

We aimed to assess the risk of preterm birth in those with real-time dynamic cervical shortening. A retrospective matched case-control study. The study group comprised all women with dynamic cervical shortening (≥4 mm) noted from 24 to 34 weeks of gestation during 2010–2017 at a university hospital. Two control groups of women were established by matching the minimal and maximal cervical length measured, as well as age, parity, gestational age, history of spontaneous preterm birth, symptoms of preterm labor, and delivery year. Data from 339 women were analyzed, 113 with dynamic cervical shortening comprised the study group, and two groups with 113 women each, matched for the minimal and maximal cervical lengths measured comprised the control groups. Rates of spontaneous preterm birth rate at <37 weeks (32.7% vs. 15.9%; OR [95% CI]: 2.60 (1.36, 4.87), p =.004) and <35 weeks (15.9% vs. 5.3%; OR [95% CI]: 3.38 (1.29, 8.86), p =.013) were significantly higher among those with dynamic cervix than among the control group matched for the maximal cervical length, and comparable to the control group matched for the minimal cervical length. The negative predictive values of cervical length for preterm birth occurrence at various cutoff values were lower in those with dynamic cervix. The minimal cervical length measured should be used to guide patient management when dynamic cervix is noted. In the setting of dynamic cervical change, the value of cervical length as a negative predictor of preterm birth is limited. [ABSTRACT FROM AUTHOR]

Leiomyoma, commonly known as fibroids, is a common female disease. Leiomyoma of the round ligament of the uterus is rare. Extraperitoneal leiomyoma of the round ligament can present as inguinal and vulvar mass mimicking an incarcerated hernia, lymph node, or lipomas. We are presenting a rare case of a 53-year-old female patient who was admitted to the hospital with a right inguinal mass. Our patient underwent surgery, and a leiomyoma of the round ligament was found. Before surgery, sonography and computed tomography (CT) will be helpful in the diagnosis of extraperitoneal leiomyoma of the round ligament.

Ultrasound is gaining increasing popularity among anesthesiologists as it is readily available and provides real-time imaging for various procedures. It is considered as a “visual stethoscope” of the anesthesiologist. After establishing its use in regional blocks and central venous catheter insertion, it is now finding increasing use in anticipation of difficult airway and securing and maintaining it. It has challenged the classical approach of clinical assessment of airway and allows more dynamic bedside assessment. This article attempts to briefly outline the role of ultrasound and its applications for airway management in patients.

Objective: Pulsatile tinnitus (PT) caused by an aberrant artery is rare. We report an unprecedented cause of PT resulting from an aberrant artery coursing the mastoid surface, and qualitatively discuss the pathophysiology of PT.Methods: This case study reports a 41-year-old woman who presented with persistent PT at her right retromastoid region. Contrast-enhanced computed tomography revealed an aberrant branch of the artery that coursed over the cortex of the mastoid bone. Surgical ligation of this aberrant artery was performed under local anesthesia.Results: Intraoperative findings suggested that PT transmitted via bone-conduction route due to the direct contact of the vascular and mastoid surface. PT was completely resolved upon surgical removal of this causative segment. Ultrasonographic and hemodynamic analysis showed that the turbulent kinetic energy and high regional wall pressure were the major contributory factors causing PT. Spectro-temporal analysis showed that PT fluctuates at frequency 500~2000 Hz, which differs from those of venous PT.Conclusion: Judicious preoperative and intraoperative assessments of PT ensure the surgical efficacy of PT. Objective ultrasonographic and computational studies can provide detailed hydroacoustic characteristics of PT. [ABSTRACT FROM AUTHOR]

Background: Achilles tendon rupture is a common injury with increasing incidence due to the rising popularity of high-velocity sports, continued physical activity of the aging American population, and use of fluoroquinolones and steroid injections. The diagnosis can often be missed or delayed, with up to 20% misdiagnosed, most commonly as an ankle sprain.Objective: The aim of our study was to systematically evaluate the reported sensitivity, specificity, and likelihood ratios of ultrasound for detecting Achilles tendon rupture in patients who were treated surgically.Methods: In January 2020, we performed a literature search of MEDLINE and EMBASE databases to identify eligible articles according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria were original studies with at least five patients, which reported data on the sonographic diagnosis of Achilles tendon rupture (complete or partial) compared to surgery as the reference standard.Results: A total of 15 studies with 808 patients were included in the primary analysis. The sensitivity of ultrasound for detecting complete Achilles tendon ruptures was 94.8% (95% confidence interval [CI] 91.3-97.2%), specificity was 98.7% (95% CI 97.0-99.6%), positive likelihood ratio was 74.0 (95% CI 31.0-176.8), and negative likelihood ratio was 0.05 (95% CI 0.03-0.09), in patients who underwent surgical treatment.Conclusions: The results from our study suggested that a negative ultrasound result may have the potential to rule out a complete, as well as a partial, Achilles tendon rupture.

Abstract Background Ultrasonography has become an indispensible tool in the management of obstetric patients. Accurate determination of fetal gestational age (FGA) has posed great challenge to patient management as the accuracy of traditional biometric parameters decreases with advance in gestation age. Accuracy of fetal kidney length (FKL) in the determination of FGA at third trimester has been documented in other population. This study is aimed to create baseline reference values of fetal kidney lengths in a Nigerian population as previous studies show population specific variations. Methods This prospective cross sectional study was carried out on 534 pregnant women between 20 and 40 weeks of gestation who met the inclusion criteria at Diamond Biomedical Services Ltd. A pilot study was conducted on 20 patients to determine the reproducibility and reliability of ultrasound measurement of FKL. Fetal kidney lengths were calculated as mean of three separate measurements. The 5th, 50th and 95th percentiles were calculated using least squared regression analysis. Third polynomial regression models were used to establish the relationship between right and left FKL and FGA. Results Both FKL measurements are highly reproducible with excellent correlation and agreement within and between sonographers. It correlates strongly with gestational age while the relationships between right and left kidney lengths with gestational age were established using the following regression equations: RKL = − 11.18 + 1.193 × FGA − 0.0350 × FGA2 + 0.00037 × FGA3 and LKL = − 12.57 + 1.332 × FGA − 0.0390 × FGA2 + 0.00040 × FGA3 for right and left kidneys respectively. Conclusion Nigerian population specific baseline reference values of FKLs for the estimation of FGA should be adopted rather than relying on the Caucasians values as universal patterns.

Introduction: Focal nodular hyperplasia, a benign liver tumour, is the second most common focal benign liver lesion, after a cavernous haemangioma. Contrast-enhanced ultrasound is used increasingly for the diagnostic work up and follow-up of focal liver lesions in adults, but is particularly valuable in the paediatric population, with the ability to reduce radiation and the nephrotoxic contrast agents used in computed tomography or magnetic resonance imaging. Confident recognition of focal nodular hyperplasia is important; it is benign, usually asymptomatic, of no clinical significance, of no clinical consequence or malignant potential. We present a case of focal nodular hyperplasia of the liver with its characteristic findings on conventional ultrasound, contrast-enhanced ultrasound with quantitative analysis and correlated with magnetic resonance imaging. Case presentation: A 15-year-old female with right upper quadrant abdominal pain was referred for liver ultrasound. A focal liver lesion was detected on B-mode ultrasound examination, and colour Doppler demonstrated no specific features. Contrast-enhanced ultrasound examination demonstrated early arterial enhancement, with a characteristic spoke-wheel pattern, centrifugal uniform filling of the lesion on the late arterial phase and sustained enhancement on the portal venous phase. Quantitative contrast-enhanced ultrasound has been performed, showing a typical curve of enhancement, as well as characteristic parametric images, supporting the interpretation of contrast-enhanced ultrasound and assisting the diagnosis. Magnetic resonance imaging demonstrated a central T2 hyperintense scar and similar enhancement characteristics as contrast-enhanced ultrasound on T1 gadolinium-enhanced sequences. Conclusion: Contrast-enhanced ultrasound is a useful technique for the differentiation of benign from malignant liver lesions and has the potential to establish the diagnosis of focal nodular hyperplasia, based on the enhancement pattern, which is similar to that observed on magnetic resonance imaging but can be better appreciated with superior temporal, contrast and spatial resolution of contrast-enhanced ultrasound.

Supplemental digital content is available in the text. Objective: Foot deformities are one of the most common musculoskeletal problems in children with cerebral palsy (CP). These deformities affect the walking ability and function of the patients. Talar cartilage is the hyaline joint cartilage of the tibiotalar joint that plantarflexes and dorsiflexes of the ankle. The aim of this study was to determine whether talar cartilage thickness was affected in children with ambulant diplegic CP. Design: Forty patients with diplegic CP (19 boys, 21 girls) and 40 age-, sex-, and weight-matched healthy control subjects (20 boys, 20 girls) were included in the study. The demographic and clinical characteristics of the patients, including age, sex, and body mass index, were recorded. Patients were classified using the Gross Motor Function Classification System. A 12-MHz linear probe was used for ultrasonographic cartilage measurements at the tibiotalar joint according to European Musculoskeletal Ultrasound Study Group (EURO-MUSCULUS) and the Ultrasound Study Group in Physical and Rehabilitation Medicine (USPRM) scanning protocols. Results: Mean talar cartilage thickness was significantly decreased in the CP group compared with the healthy control group (P < 0.001). There was a significant negative correlation between Gross Motor Function Classification System levels and talar cartilage thickness measurements (P < 0.001, Tb = −0.695). Conclusion: This study demonstrates that patients with CP have a thinner talar cartilage compared with healthy control subjects. [ABSTRACT FROM AUTHOR]

Amniotic fluid is an important component that engulfs the fetus inside the mother's womb. Oligohydramnios, means abnormally decreased in the amount of amniotic fluid It has a risk to the fetus during pregnancy, affect about 1 to 2 percent of pregnancies, iatrogenic preterm causes illness and death to the fetus before delivery. Operative deliveries are risky for both the fetus and the mother. They might cause problems due to some of the commonly known factors or Oligohydramnios association could be identified, there could be some other unknown factors that are termed "Isolated Oligohydramnios". Amniotic fluid's rate of evolution could serve as an indicator to how the fetus is growing, it can provide protection, and it helps predict the gender of the newborn. The mother should undertake a hydration therapy in order to improve her amniotic fluid and the fetus well been. Drinking good amounts of water found to be helpful in increasing the amniotic fluid volume without using any other supplements. The sonographic evaluation for all patients with oligohydramnios were reviewed to determine whether sonographically detectable fetal anomalies were present, and when these anomalies were present, how this information was used in maternal fetal management.

Background: Renal parenchymal thickness (RPT) was found to be a vital parameter that can offer prognostic information on end-stage kidneys diseases. The aim of the current study was to establish normal RPT value in our population; and to reveal its relationship with age, height, and weight. Method: It was a cross-sectional analytic study conducted in the department of radiology/Azaditeaching hospital at Kirkuk city, where the sonographic assessment of RPT was performed from January 2016 to May 2018 for 253 adults with different complaints; Individuals with history of medical disorders/drugs known to affect the kidney, malignancy, pregnancy, those who had renal variant/pathology during ultrasound examination and abnormal laboratory tests were excluded from the study. Differences of RPT between two sides and gender were assessed with student‘s t-test, and its correlation with age, height, and weight were assessed with the Pearson’s correlation coefficient (r). Results: In males, the mean value (SD) of right RPT was 18.2(3.2) mm, and left RPT was 18.9(3) mm. In females, it was 16.4(2.4)mm in the right kidney and 16.9 (2.4) mm in left kidney. There was no statistical difference between RPT of the right and left kidneys (p = 0.0001). The RPT was significantly thicker in males (18.6 mm versus 16.7 mm) (P= 0.0001). There was significant moderate and strong negative correlation with age in right and left kidney respectively. There was a positive correlation with a person’s height and weight which was significant (P= 0.00001). Conclusion: Our population parenchymal thickness values are different from others, it is 18.6 mm male and 16.7 mm in female, parenchyma is considered thin if it was less than 13 mm in males and 10 mm in females, its decreased with age, taller and more obese persons have thicker parenchyma on both sides.

Aim: To establish the sonographic measurement of the diameter of the inferior vena cava as a predictor of shock in trauma patients. Materials and Method: A cross-sectional study to determined the sonographic measurement of the inferior vena cava to 40 patients attended at Hospital Domingo Luciani trauma unit, in the period between January and April of 2018. Two groups were selected; group 1: shock patients, those with systolic blood pressure lower than 90 mm Hg, and the group 2: control patients that kept normal blood pressure. The image study of the inferior vena cava was carried out with the ALOKA prosound ultrasound equipment SSD a5 and with the portable ultrasound MicroMaxx SonoSite, in which the collapsibility index was measured. The findings were recorded in the data collection sheet. The statistical analysis proposed for the comparison of averages was made with the student's t-test for independent samples and the assessment of diagnostic cut-off points was made with a ROC curve. Results: the mean of collapsability index of de IVC for control and shock group were 26 ± 12,7% and 58,5 ± 5,9%, respectively; The collapsability index (CI) was > 50% in all patients of shock group. Conclusions: The measurement of the ICV diameter is a predictor of shock, being the IC the most sensitive and specific parameter. [ABSTRACT FROM AUTHOR]

BACKGROUND: Hypertension, diabetes, and smoking were considered to be associated with several public health problems. OBJECTIVE: the study aims to explore the hemodynamic of carotid arteries in association with hypertension, diabetes, and smoking in Sudanese stroke patients. MATERIALS AND METHODS: In a quantitative descriptive study, fifty patients with stroke were scanned by B-mode and Doppler sonography. Carotid arteries were investigated with a 7-MHz linear transducer by a standard carotid sonography protocol. RESULTS: The average Doppler resistive index (RI) was 0.71 ± 0.084 and intima-media thickness was 1.39 ± 0.78 mm. The end diastolic velocities (EDVs) and peak systolic velocities (PSVs) of common carotid arteries were significantly changed in smokers and hypertensive (P < 0.05). The elevation of RI in right and left CCAs were significantly correlated with smokers (P = 0.017 and 0.010 respectively). Hemorrhagic stroke was most prevalent in hypertensive rather than diabetic and smokers. The carotid hemodynamics changed significantly in hypertensive and smokers more than diabetics. CONCLUSION: EDV and PSV were significantly correlated with hypertension and tobacco smoking rather than diabetes. Hypertension, diabetes, and smoking have an association with stroke and hand significant effect on carotid artery hemodynamic and atherosclerotic disease. The Doppler RIs were significantly correlated with smokers. Patients with risk factors of stroke should be scanned with Doppler sonography as early as possible.

Objective: In patients with traumatic brain injury (TBI), early detection and subsequent prompt treatment of elevated intracranial pressure (ICP) is a challenge in the prehospital setting, because physical examination is limited in comatose patients and invasive device placement is not possible. The aim of this study was to evaluate the quality and feasibility of optic nerve sheath diameter (ONSD) measurements obtained during the prehospital management of patients with TBI. Methods: This study was a prospective, observational study of 23 patients with moderate and severe TBI during prehospital medical care. The primary endpoint was the quality of ONSD measurements expressed as the percentage of ONSD validated by the experts. Secondary endpoints included the feasibility of ONSD measurements as the percentage of ONSD performed and assessment by operators of ease and duration to perform. Results: Ultrasound ONSD was performed in 19 (82%) patients and 80% of ONSD measurements were validated by the experts. The ONSD measurements were possible in 15 (79%) cases. The physicians have assessed the ease of use at 8 (interquartile range [IQR] = 2.5-8) on 10 for and the median time to obtain ONSD measurement was 4 min (IQR = 3-5). ONSD measurement was performed in 12 (63%) cases during the transport and in 7 (37%) cases on scene, with 58% (n = 7) and 71% (n = 5) validated ONSD, respectively. The success rate in the helicopter was 43% compared to 80% in the ambulance. Conclusion: This study shows that it is feasible to obtain high-quality ONSD measurements in the management of patients with TBI in a prehospital setting. A randomized study evaluating the usefulness of ONSD to guide management of TBI in the prehospital phase may be of great interest. [ABSTRACT FROM AUTHOR]

Background: With the growing utilization of ultrasonography in emergency medicine combined with the concern over adequate pain management in the emergency department (ED), ultrasound guidance for peripheral nerve blockade in ED is an area of increasing interest. The medical literature has multiple reports supporting the use of ultrasound guidance in peripheral nerve blocks. However, to perform a peripheral nerve block, one must first be able to reliably identify the specific nerve before the procedure. Objective: The primary purpose of this study is to describe the number of supervised peripheral nerve examinations that are necessary for an emergency medicine physician to gain proficiency in accurately locating and identifying the median, radial, and ulnar nerves of the forearm via ultrasound. Methods: The proficiency outcome was defined as the number of attempts before a resident is able to correctly locate and identify the nerves on ten consecutive examinations. Didactic education was provided via a 1 h lecture on forearm anatomy, sonographic technique, and identification of the nerves. Participants also received two supervised hands-on examinations for each nerve. Count data are summarized using percentages or medians and range. Random effects negative binomial regression was used for modeling panel count data. Results: Complete data for the number of attempts, gender, and postgraduate year (PGY) training year were available for 38 residents. Nineteen males and 19 females performed examinations. The median PGY year in practice was 3 (range 1-3), with 10 (27%) in year 1, 8 (22%) in year 2, and 19 (51%) in year 3 or beyond. The median number (range) of required supervised attempts for radial, median, and ulnar nerves was 1 (0-12), 0 (0-10), and 0 (0-17), respectively. Conclusion: We can conclude that the maximum number of supervised attempts to achieve accurate nerve identification was 17 (ulnar), 12 (radial), and 10 (median) in our study. The only significant association was found between years in practice and proficiency (P = 0.025). We plan to expound upon this research with an additional future study that aims to assess the physician′s ability to adequately perform peripheral nerve blocks in efforts to decrease the need for more generalized procedural sedation.

Background: Hydrocephalus among children is an important medical problem in view of its neurological sequelae in the growing child. This situation is compounded by the acute shortage of neurosurgeons in third world countries like Nigeria; hence, the need for its early detection and proper management. Objective: Evaluation of the ultrasound (US) appearances in children under 5 years of age presenting with clinical signs of raised intracranial pressure suggestive of hydrocephalus. Patients and Methods: A retrospective review of transfontanelle US scans done in 64 children (39 boys and 25 girls) attending the Department of Radiology, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria over a period of 2 years was carried out. The patients had a mean age of 5.0 ± 4.6 months (range: 1–60 months) at the time of their US examination. Some of the clinical indications for US scan included: Congenital hydrocephalus, encephalocele, meningomyelocele, and meningitis. All scans were performed through the anterior fontanelle using SIUI Apogee 800 PLUS scanner with a curvilinear probe using multi-frequency transducer of 2–5 MHz. Results: Fifty-two patients (81.3%) had hydrocephalus of congenital origin. Eleven cases (17.2%) had postmeningitic hydrocephalus while only 1 case (1.6%) was posthemorrhagic. Twenty-five patients (48.0%) of the congenital cases were due to cerebral aqueduct stenosis. Eleven (21.2%) of the congenital cases were from obstruction at the exit foramina of Luschka and Magendie resulting in the communicating type of hydrocephalus. Conclusion: Hydrocephalus is a known cause of neurological morbidity among infants in developing countries. Majority of the cases are congenital in origin and most commonly due to cerebral aqueduct stenosis. Transfontanelle US is cheap, affordable, nonhazardous, and more accessible than other imaging modalities. It should serve as the first-line investigation of infants with suspected hydrocephalus for early detection and monitoring of progression to determine those cases that would require shunt operation.

Purpose: To assess the prospective sonographic diagnosis of molar pregnancy and compare sonographic features of complete versus partial molar pregnancy.Methods: This institutional review board--approved retrospective chart review conducted between 2001 and 2011 identified 70 women with a histopathologic diagnosis of molar pregnancy and with available sonograms. Clinical data, images, and reports were reviewed, and features enumerated by radiologists blinded to the final diagnosis.Results: Mean age of patients was 30.5 ± 7.0 (SD) years (range, 16-49 years) with a mean gravidity of 3.2 ± 2.3 (SD) (range 1-11). Mean gestational age was 74.0 ± 19.1 day (range 39-138) and serum β-human chorionic gonadotropin was 131 ± 156 mIU/ml (range 447-662,000). Pathologic results showed 48 partial and 22 complete molar pregnancies. Sonographically, partial moles more commonly showed a yolk sac (56.3% versus 0%, p < 0.0001), fetal pole (62.5% versus 4.6%, p < 0.0001), fine septa within the sac (25.0% versus 4.6%, p = 0.05), and normal (31.3% versus 0%, p = 0.002) or minimally cystic placenta (27.1% versus 4.6%, p = 0.49), while complete moles had larger gestational sacs (612 versus 44 mm, p = 0.005), were more often avascular on color Doppler imaging (45.5% versus 18.8%, p = 0.02), had more often abnormal tissue in the uterus (82.6% versus 20.8%, p < 0.0001) and placental masses (86.9% versus 16.7%, p < 0.0001), and were more often diagnosed prospectively (86.4% versus 41.7%, p = 0.0005).Conclusions: Complete molar pregnancy is associated with marked cystic changes and mass formation and is often diagnosed sonographically. Partial molar pregnancy often presents with minor cystic changes of the placenta and remains underdiagnosed sonographically. However, correct prospective diagnosis was made more frequently in this study than in older reports, perhaps due to improved spatial resolution of sonographic equipment. © 2016 Wiley Periodicals, Inc.

Benign diseases are more common that malignant diseases in pregnant and lactating women. Fibroadenomas are the most commonly identified benign breast tumour in pregnant and lactating women. Pregnancy related breast cancer is defined as breast cancer that occurs during pregnancy or within 1 year of delivery. Its incidence is estimated at 1 in 3000 to one in 10 000 pregnancies.Several reproductive factors like age at menarche, age at menopause, age at full-term pregnancy, parity, age at any birth and spacing of pregnancies, breast feeding, characteristics of the menstrual cycle, infertility, spontaneous and induced abortions, characteristics of the menstrual cycle and infertility are some of the factors that have been incriminated as risk factors for breast cancer. We sought to describe the predominant breast pattern, sonographic array of pregnancy related breast diseases in women referred to the breast imaging unit in the department of Radiology at the University College Hospital, Ibadan south west Nigeria. Socio-demographic characteristics in these women were also evaluated. Archived images were reviewed and documented and data was analysed with SPSS version 17 and presented with descriptives. In this descriptive study, we retrospectively retrieved the sonomammographic records of 21 women (pregnant or lactating) referred to and imaged in the department of radiology, University college hospital Ibadan, between 2006 and 2013. Diagnostic breast sonograms performed by MO and ATS; Consultant radiologists with 7-10 years' experience utilizing a 7-10 MHz transducer of the General electric GE Logiq P5 machine was employed for the scans. Twenty-one women with ages between 22-42 years (Mean 31.4 ,5.4 SD) pregnant or lactating were referred to the radiology department for sonomammographic evaluation. Majority of the women were in the 3rd decade. Referral was mainly (11) by family physicians from the general outpatient clinic,5 were self-referred, 2 from radiotherapy department ,2 from obstetrics and gynaecology department and 1 from the surgical outpatient clinic. Nineteen (89.5%) were lactating and breastfeeding while 2 (10.5%) were pregnant. Nipple discharge (89.5%) was the predominant presenting complaint in the study. They were all married with the majority attaining menarche at age 14.6,2.1 SD years. Most of the women were multi-parous 17(89.5%) and possessed higher education 17 (81.0%). Twenty (96.0%) women had no previous breast disease while only 1 (4.0%) woman had a positive family history of breast cancer. They weighed between 44-102kg (mean 69.84kg,15.33SD). Their mean height was 159.8cm. Waist hip ratio was between 0.69-0.93 (Mean 0.83). The heterogeneous fibroglandular pattern was predominant in 15 (71.4%) women. Final BIRADS assessment of 2 was most frequent (11/21) 52.4% while 19.0% were assigned to BIRADS categories 0 and 1 (4/21). Histological diagnosis of Invasive ductal carcinoma was made in the 3 women with final BIRADS of 5. Abnormal nipple discharge is the most common complaint. Breast diseases found in most pregnant and lactating women were benign. It is important to note that malignant breast lesions can also occur in this group of women who may assume that the changes noted in their breast are due to lactation.

Purpose: A fetus with skeletal disorder poses diagnostic challenges in a resource-poor setting with limited management options. The objective of the study was to develop a step-by-step approach for the diagnosis of skeletal dysplasia in light of the limited resources available.Methods: An algorithmic approach was used. The assessment for lethality was the first step, followed by the evaluation for fractures. In cases without evidence of fracture, severe constriction of thorax or associated polydactyly were searched for. In cases without severe thoracic constriction, the severity of micromelia was evaluated. After delivery, fetal examination was done to ascertain the etiology.Results: During the 6-year period, 41 cases with shortened long bones were fully evaluated. Lethality was suspected in 30 cases. Fracture and beading were present in eight cases, and severe thoracic constriction with polydactyly was observed in seven cases. Mild micromelia was seen in 19 cases and severe micromelia in 7 cases. Among lethal skeletal dysplasias, thanatophoric dysplasia was most common (six cases). Among nonlethal skeletal dysplasias, achondroplasia was seen in eight cases.Conclusions: Lethality of skeletal dysplasia could be predicted on prenatal ultrasound with 100% accuracy. The step-by-step approach was helpful to characterize skeletal dysplasias. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:529-539, 2016. [ABSTRACT FROM AUTHOR]

Background: With the growing utilization of ultrasonography in emergency medicine combined with the concern over adequate pain management in the emergency department (ED), ultrasound guidance for peripheral nerve blockade in ED is an area of increasing interest. The medical literature has multiple reports supporting the use of ultrasound guidance in peripheral nerve blocks. However, to perform a peripheral nerve block, one must first be able to reliably identify the specific nerve before the procedure. Objective: The primary purpose of this study is to describe the number of supervised peripheral nerve examinations that are necessary for an emergency medicine physician to gain proficiency in accurately locating and identifying the median, radial, and ulnar nerves of the forearm via ultrasound. Methods: The proficiency outcome was defined as the number of attempts before a resident is able to correctly locate and identify the nerves on ten consecutive examinations. Didactic education was provided via a 1 h lecture on forearm anatomy, sonographic technique, and identification of the nerves. Participants also received two supervised hands-on examinations for each nerve. Count data are summarized using percentages or medians and range. Random effects negative binomial regression was used for modeling panel count data. Results: Complete data for the number of attempts, gender, and postgraduate year (PGY) training year were available for 38 residents. Nineteen males and 19 females performed examinations. The median PGY year in practice was 3 (range 1--3), with 10 (27%) in year 1, 8 (22%) in year 2, and 19 (51%) in year 3 or beyond. The median number (range) of required supervised attempts for radial, median, and ulnar nerves was 1 (0--12), 0 (0--10), and 0 (0--17), respectively. Conclusion: We can conclude that the maximum number of supervised attempts to achieve accurate nerve identification was 17 (ulnar), 12 (radial), and 10 (median) in our study. The only significant association was found between years in practice and proficiency ( P = 0.025). We plan to expound upon this research with an additional future study that aims to assess the physician's ability to adequately perform peripheral nerve blocks in efforts to decrease the need for more generalized procedural sedation.

Introduction. Carpal tunnel syndrome is the most frequent type of upper limb compression neuropathies. Sometimes, it's quite difficult to diagnose it only by the signs and syptomes observed by the examiner. Using ultrasound examination to assess the median nerve in the carpal tunnel syndrome is a relatively recent acquisition, but as imaging techniques have evolved, some authors consider that sonography can even replace electrophysiological studies. Material and methods. The study included 29 asymptomatic subjects without injuries at the level of carpal tunnel or palmar region and 7 patients hospitalized in the Department of Plastic Surgery of SUUB diagnosed with carpal tunnel syndrome. For each of the persons included in the study median nerve cross-sectional area was measured. Results. The cross-sectional area of the median nerve fot the asymptomatic subjects were between 8.5 and 14.2 mm2, with a mean value of 10,18±1,55 mm2. A cross-sectional area value above 10, 182 mm2 can be suggestive for the presence of carpal tunnel syndrome, when associated with characteristic signs and symptoms. Conclusions. Sonographic examination of the median nerve and measurement of its cross-sectional area is a useful diagnostic tool in the evaluation of carpal tunnel syndrome. [ABSTRACT FROM AUTHOR]

Purpose: To assess the interrater reliability and test characteristics of lower limb sonographic examination for the diagnosis of deep venous and proximal great saphenous vein thrombosis when performed by Emergency Physicians (EPs) as compared to that by the Department of Radiology (Radiology). The secondary objective was to assess the effects of patient body mass index and EP satisfaction with bedside ultrasound on sensitivity and specificity.Methods: A prospective study was conducted for patients with clinical suspicion for lower extremity thrombus. EPs evaluated for venous thrombosis in the common femoral vein, femoral vein of the thigh, popliteal vein, and proximal great saphenous vein. Subsequently, all patients received ultrasounds by Radiology, the criterion standard.Results: One hundred ninety-seven patients (257 individual legs) were evaluated. There was 90-95% agreement between EP and Radiology, moderate kappa agreement for common femoral vein, and femoral vein of the thigh and fair kappa agreement for great saphenous vein and popliteal vein. The sensitivity and specificity of EP ultrasounds compared with criterion standard were lower than previously reported. There was no trend in patient body mass index or provider satisfaction influencing the test characteristics.Conclusions: Our study suggests that point-of-care sonography should not replace Radiology-performed scans. The required amount of training for EPs to be competent in this examination needs further investigation. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:360-367, 2016. [ABSTRACT FROM AUTHOR]

Purpose: To compare the strength of correlation between automatically measured carotid lumen diameter (LD) and interadventitial diameter (IAD) with plaque score (PS). Methods: Retrospective study on a database of 404 common carotid artery B-mode sonographic images from 202 diabetic patients. LD and IAD were computed automatically using an advanced computerized edge detection method and compared with two distinct manual measurements. PS was computed by adding the maximal thickness in millimeters of plaques in segments taken from the internal carotid artery, bulb, and common carotid artery on both sides. Results: The coefficient of correlation was 0.19 (p < 0.007) between LD and PS, and 0.25 (p < 0.0006) between IAD and PS. After excluding 10 outliers, coefficient of correlation was 0.25 (p < 0.0001) between LD and PS, and 0.38 (p < 0.0001) between IAD and PS. The precision of merit of automated versus the two manual measurements was 96.6% and 97.2% for LD, and 97.7% and 98.1%, for IAD, respectively. Conclusions: Our automated measurement system gave satisfying results in comparison with manual measurements. Carotid IAD was more strongly correlated to PS than carotid LD in this population sample of Japanese diabetic patients. [ABSTRACT FROM AUTHOR]

Post-pancreatitis pseudoaneurysms are not uncommon. They have a high associated mortality due to a propensity to rupture. Current standards of treatment advocate immediate intravascular interventions. We describe two cases of alcohol-related post-acute pancreatitis pseudoaneurysms arising from the second-order branches of the superior mesenteric artery (SMA) that were endoluminally inaccessible. Both cases were successfully treated with percutaneous thrombin injection into the pseudoaneurysm sac under ultrasound guidance. We suggest that endoluminally inaccessible pseudoaneurysms that are percutaneously accessible can be expeditiously treated with percutaneous thrombin injection. Further, due to the efficaciousness of this procedure, it could be considered as a first-line minimally invasive therapeutic option. [ABSTRACT FROM AUTHOR]

Detection and monitoring of blood loss in trauma patients can often be challenging. Change in the inferior vena cava diameter (IVCd) occurs due to alteration in circulating blood volume (CBV) and blood loss. Ultrasonographic measurement of IVCd provides a noninvasive real-time information of the CBV. The present study was designed to determine whether acute blood loss could be detected by sonographic measurement of the IVCd. A total of 50 volunteer blood donors aged 18 to 57 years were studied in the Department of Radiology and Imaging of Dhaka Medical College Hospital (DMCH) from July 2004 to June 2005. The inferior vena cava diameters, both during inspiration and expiration were measured by ultrasound examination immediately before and after donation of a single unit (450ml) of blood. During examination, the transducer was applied to the epigastrium parallel to the median line about 2 cm to the right of it for sagittal sections, and at a right angle to the median line about 3 cm below the xiphoid process for transverse sections. In sagittal sections, the inferior vena cava behind the liver were imaged during inspiration and expiration. The mean diameter of IVC during expiration before and after the blood donation was 17.5mm (±1.56mm) and 11.93mm (±1.48mm) respectively. Likewise, the mean diameter of IVC during inspiration before and after the blood donation was 12.96mm (±1.61mm) and 7.58mm (±1.29mm) respectively. The decrease in INV diameter following blood loss was significant (p< 0.01). Thus, the acute depletion of CBV could be detected by measuring the change of IVCd by sonography. Further study may be undertaken to determine the relationship of unit change of IVCd due to acute blood loss in case of trauma or other conditions. Ibrahim Med. Coll. J. 2011; 5(2): 51-53

Acute variceal bleeding in patients with liver cirrhosis and portal hypertension (PHT) is the most serious emergency complication among those patients and could have catastrophic ‎outcomes if not timely managed. ‎Early screening by esophago-gastro-duodenoscopy (EGD) for the presence of esophageal varices (EVs) is ‎‎currently recommended by the practice guidelines for all cirrhotic patients. Meanwhile, EGD is not readily accepted or preferred by many patients. The literature is rich in ‎studies to investigate and validate ‎ non-invasive markers of EVs prediction aiming at reducing the unneeded endoscopic procedures. Gallbladder (GB) wall thickness (GBWT) ‎measurement has been found promising in many published research ‎articles. We aim to highlight the validity of sonographic GBWT measurement in the ‎prediction of EVs based on the available evidence.‎ We searched databases including Cochrane library, PubMed, Web of Science and many others for relevant articles. GBWT is associated with the presence of EVs in cirrhotic patients with PHT of different etiologies. The cut-off of GBWT that can predict the presence of EVs varied in the literature and ranges from 3.1 mm to 4.35 mm with variable sensitivities of 46%-90.9% and lower cut-offs in viral cirrhosis compared to non-viral, however GBWT > 4 mm in many studies is associated with acceptable sensitivity up to 90%. Furthermore, a relation was also noticed with the degree of varices and portal hypertensive gastropathy. Among cirrhotics, GBWT > 3.5 mm predicts the presence of advanced (grade III-IV) EVs with a sensitivity of 45%, the sensitivity increased to 92% when a cut-off ≥ 3.95 mm was used in another cohort. Analysis of these results should carefully be revised in the context of ascites, hypoalbuminemia and other intrinsic GB diseases among cirrhotic patients. The sensitivity for prediction of EVs improved upon combining GBWT measurement with other non-invasive predictors, e.g., platelets/GBWT., Competing Interests: Conflict-of-interest statement: All the authors report having no relevant conflicts of interest for this article., (©The Author(s) 2023.

Objectives: Developmental dysplasia of the hip (DDH) is a condition with variation among ethnicities and regions. We aimed to investigate the effect of a gestational week of birth on the sonographic acetabular hip angles of newborns., Methods: We prospectively scanned the hips of neonates born in a single, tertiary hospital during their first week of life, using the Graf sonographic method. Demographics, obstetric history of the mother, birth weight, parity, presentation, family history of developmental dysplasia of the hip (DDH), gender, mode of delivery, single/multiple birth, and gestational age were recorded. Acetabular α and β angles were measured, and hip type was determined according to Graf's classification. Patients were divided according to the gestational age of birth (<37 weeks, 37-38, 38-39, 39-40, >40 weeks)., Results: From May- October 2020, 342 babies (684 hips) were examined (52.9% males / 47.1% females). 76.7% were Caucasian-Greek, and 88.3% were term babies. There was a significant difference between the α-angles of the right and left hip in both genders. More females had Type II hips than males. Subgroup analysis did not reveal a significant difference in hip angles of term babies. There was no correlation between birth weight or gestational age and hip angles. Female gender and the existence of maternal thyroidopathy were positively correlated with Type II hips., Conclusion: Gestational birth age in term infants is unimportant regarding acetabular hip angles. Female gender and maternal thyroidopathy appeared to be related to hip type. Further investigation may be warranted to elucidate the effect of maternal thyroidopathy and hip development., Competing Interests: The author(s) do NOT have any potential conflicts of interest for this manuscript

Objective: To compare the accuracy of sonographic versus clinical methods of fetal weight estimation in a low-resource setting. Methods: This was a prospective study. Ethical clearance and informed consent were obtained. Two hundred (200) women admitted for delivery were assessed. Questionnaires and data collection forms were used to obtain socio-demographic and other clinical information. The actual weight was determined at birth. Estimated fetal weight (EFW) was compared with the actual weight (BW). The data obtained were analyzed using SPSS version 16.0 statistical software. The accuracy of clinical and sonographic fetal weight estimation was compared using Students' t-test, Chi-square test and Pearsons' coefficient of correlation and p < 0.05 was considered statistically significant. Results: The mean of absolute percentage error was smaller for ultrasonic (9.8 ± 7.2) than clinical (10.5 ± 7.5) estimation, but the difference was not statistically significant ( p = 0.083). In the 2.5-3.99 kg group there was no statistically significant difference between the mean absolute percentage errors for the two methods ( p = 0.096). In the <2.5 kg group, clinical method overestimated birth-weight while in ≥4.0 kg, the sonographic method underestimated the birth weight. For birth weight 2.5-3.99 kg, sensitivity, specificity, positive predictive value and negative predictive value were 96.9, 76.9, 98.1, 66.7% and 96.8, 75, 96.8, 75% for sonographic and clinical estimates, respectively. The predictive powers of sonographic and clinical methods were better for low birth weight and macrosomic fetuses, respectively. Conclusion: Clinical method of fetal weight estimation can only be recommended for use as screening tool for normal weight and macrosomic fetuses. [ABSTRACT FROM AUTHOR]

Histological diagnosis of Invasive ductal carcinoma was made in the 3 women with final BIRADS of 5 breast diseases found in most pregnant and lactating women were benign. It is important to note that malignant breast lesions can also occur in this group of women who may assume that the changes noted in their breast are due to lactation. [ABSTRACT FROM AUTHOR]

Background and Aims: The anatomic site and the volume of local anesthetic needed for an ultrasound-guided saphenous nerve block differ in the literature. The purpose of this study was to examine the effect of two different ultrasound-guided low volume injections of local anesthetic on saphenous and vastus medialis nerves. Materials and Methods: Recruited patients (N = 48) scheduled for orthopedic surgery were randomized in two groups; Group distal adductor canal (DAC): Ultrasound-guided injection (5 ml of local anesthetic) distal to the inferior foramina of the adductor canal. Group adductor canal (AC): Ultrasound-guided injection (5 ml local anesthetic) within the adductor canal. Following the injection of local anesthetic, block progression was monitored in 5 min intervals for 15 min in the sartorial branches of the saphenous nerve and vastus medialis nerve. Results: Twenty two patients in each group completed the study. Complete block of the saphenous nerve was observed in 55% and 59% in Group AC and DAC, respectively (P = 0.88). The proportion of patients with vastus medialis weakness at 15 min in Group AC, 36%, was significantly higher than in Group DAC (0/22), (P = 0.021). Conclusions: Low volume of local anesthetic injected within the adductor canal or distally its inferior foramina leads to moderate success rate of the saphenous nerve block, while only the injection within the adductor canal may result in vastus medialis nerve motor block.

Objective To test the clinical and sonographic predictors of testicular torsion ( TT) with the aim of reducing negative exploration rates., Patients and Methods We performed a prospective study of all boys treated for 'acute scrotum' at our institute between January 2001 and April 2012 and clinical findings were documented., If available, ultrasonography ( US) was added to the diagnostic evaluation., A prediction of the diagnosis was based on clinical and sonographic features, and was followed by surgical exploration in all patients., Results A total of 104 patients were included in the 16-month period of the study., No single finding excluded TT. The clinical features (pain <24 h, nausea/vomiting, abnormal cremasteric reflex, high position of the testis) appeared predictive (100% sensitivity) and the clinical scoring system was proven to be reliable, reducing the negative exploration rate by >55%., Ultrasound predictors alone were not able to identify all boys with TT., Conclusions It is safe to refrain from routine surgical exploration in every child with acute scrotum if the clinical score is applied, which results in a marked reduction of negative explorations., A reliable diagnosis could not be obtained based on US alone. As scrotal US is unpleasant for the child, we propose to refrain from this if the clinical score is positive. Patients with a negative clinical score are suitable candidates for US to establish and secure diagnosis. [ABSTRACT FROM AUTHOR]

Purpose To identify a combination of sonographic features that best predicts ovarian malignancy. Methods Subjects included 249 women who had a transvaginal sonogram for a pelvic mass at Brigham and Women's Hospital between December 2005 and February 2010. Subjects underwent surgery for removal of the mass and pathologic diagnosis was available. Images were reviewed retrospectively by one sonologist blinded to diagnosis and clinical information. Twelve sonographic features were scored for each mass. The dataset was divided into training (n = 149) and testing (n = 100) sets. Within the training set, a stepwise logistic regression was used to weigh each variable and combination of features to identify those associated with malignancies. Using the results from the logistic regression analyses, we created a three-level risk stratification that was applied to the sonograms of subjects in the testing set to assess its ability to distinguish benign lesions from invasive and borderline cancers. Results High risk lesions included all masses with internal vascularity. In our testing set, this feature was present in 9 out of 12 (75%) invasive cancers, 1 out of 6 (16.7%) borderline lesions, and 9 out of 82 (11%) benign masses. The intermediate risk level included lesions with a thick wall or thick septa without internal blood flow. This combination of features identified one additional invasive cancer and 5 out of 6 (83.3%) borderline tumors. Masses with low risk features had a 2/49 (4.0%) incidence of malignancy. Conclusions In the absence of high or intermediate risk sonographic features, the risk of malignancy is low. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound, 41:269-274, 2013 [ABSTRACT FROM AUTHOR]

Purpose: To establish normal values for the lower uterine segment (LUS) thickness and to recognize factors that may affect these values. Methods: In this cross-sectional study, we measured the LUS thickness in women between 11 and 41 weeks gestation. Women with placental abnormalities and fetal anomalies were excluded. Fetal weight, location of placental implantation, and cervical length were estimated. The LUS was examined to identify the thinnest zone and evaluated using the transvaginal approach with an empty urinary bladder. Full LUS thickness was measured with a caliper at the inner surface of the posterior bladder wall and another caliper at the interface between the amniotic fluid and the decidua. The myometrium was measured with the first caliper at the interface between the amniotic fluid and the deciduas and the second between the bladder wall and the myometrium. Normal values for the LUS were established throughout gestation, and correlations between the LUS gestational age, fetal weight, previous cesarean section, and other parameters were examined. Results: Overall, 350 women were included in our study. Median parity was 1 (0-6) and the majority (62%, 218/350) of women have not had a previous cesarean section. The LUS thickness inversely correlated with gestational week (Pearson's r = −0.11, p < 0.03). When stratifying the linear regression model to women with and without a history of a previous cesarean section, it was demonstrated that gestational age was moderately correlated with LUS only in the second group of patients (Pearson's r = −0.16, p = 0.1 and Pearson's r = −0.47, p < 0.0001, respectively). During the post term period, patients who had had a previous cesarean section had significantly thinner LUS compared with patients who had not had a previous cesarean section (46 mm ± 20 versus 59 mm ± 20, p = 0.002, respectively). Neither parity nor the number of previous cesarean sections were found to correlate with the thickness of the LUS ( p > 0.05). Multivariate linear regression (R2 = 0.215, F(2, 63) = 9.021, p < 0.001) demonstrated that both gestational week (β = −0.13, p < 0.04) and cesarean section (β = −0.01, p < 0.0001) were independent factors associated with the thickness of the LUS; for every 1 week increase in gestational week, there was a 1.3 mm decrease in the total thickness of the LUS Conclusions: We have established reference ranges for LUS thickness throughout gestation. The LUS thickness decreases throughout gestation in singleton pregnancies and is significantly thinner in postterm period pregnant women with a previous cesarean section. © 2013 Wiley Periodicals, Inc., J Clin Ultrasound, 2013 [ABSTRACT FROM AUTHOR]

The purpose of this article is to describe the use of three-dimensional sonography as an adjuvant to two-dimensional sonography facilitating an earlier and more definitive diagnosis of Jeune and Jeune-like syndromes in the second trimester. We report two cases in which three-dimensional sonography facilitated the diagnosis of these malformations. A diagnosis of Jeune syndrome was made in our first case. Our second case was found to be short-rib polydactyly syndrome Type IV. Three-dimensional skeletal survey visualized short ribs, short limbs, the presence of normal scapulae, and the absence of polydactyly in both cases. Three-dimensional sonography can assist two-dimensional sonography in providing a more accurate display of skeletal anomalies, limb abnormalities, and facial features. © 2011 Wiley Periodicals, Inc.
