Thanatophoric dysplasia (TD) and achondroplasia (ACH) are allelic disorders caused by a constitutively active mutation in the FGFR3 gene. Because TD is a lethal disorder and ACH is non-lethal, they need to be distinguished after ultrasound identification of fetal growth retardation with short limbs. Accordingly, we have developed a noninvasive prenatal test using cell-free fetal DNA in the maternal circulation to distinguish TD and ACH. A multiplex PCR system encompassing five mutation hotspots in the FGFR3 gene allowed us to efficiently identify the responsible mutation in cell-free DNA in all examined pregnancies with a suspected TD or ACH fetus...

Osteoporosis and sarcopenia represent two major health problems with an increasing prevalence in the elderly population. The correlation between these diseases has been widely reported, leading to the development of the term "osteosarcopenia" to diagnose those patients suffering from both diseases. Several imaging methods for the diagnosis and management of osteoporosis exist, with dual-energy X-ray absorptiometry (DXA) being the most commonly used for measuring bone mineral density (BMD). Imaging technique other than DXA is represented by conventional radiography, computed tomography (CT) and ultrasound (US)...

The present study evaluated three-dimensional shear wave elastography (3D SWE) in the detection of clinically significant prostate cancer. Clinically significant prostate cancer was defined by a minimum of one biopsy core with a Gleason score of 3+4 or 6 with a maximum cancer core length >4 mm. Patients with serum prostate-specific antigen levels of 4.0-20.0 ng/ml who were suspected of having prostate cancer from multi-parametric magnetic resonance imaging (mpMRI) were prospectively recruited. The 3D SWE was performed pre-biopsy, after which patients underwent MRI-transrectal ultrasound image-guided targeted biopsies for cancer-suspicious lesions and 12-core systematic biopsies...

Ovarian reserve represents the number of available follicles/oocytes within ovaries and it can be assessed by follicle stimulating hormone levels, anti-Müllerian hormone levels, and/or antral follicle count determined by ultrasounds. A low ovarian reserve is defined by an abnormal ovarian reserve test. This condition can be considered premature if it occurs before the age of 40, leading to premature ovarian insufficiency. Despite the growing knowledge concerning the genetic basis of ovarian deficiency, the majority of cases remain without a genetic diagnosis...

The "drooping lily" sign is identified on intravenous urography or voiding cystourethrography in patients with a duplicated renal collecting system and refers to inferolateral displacement of a functioning lower pole moiety by an obstructed upper pole collecting system. In this case, a 2-month-old girl with a prenatal diagnosis of hydronephrosis was found to have a "scintigraphic drooping lily" sign on Tc-dimercaptosuccinic acid renal scan. Evaluation with ultrasound and voiding cystourethrography confirmed a duplicated collecting system and obstructed upper pole moiety...

BACKGROUND: Fetal occiput posterior position in labor is associated with more painful and prolonged labor, and an increase in both maternal and fetal morbidity. The aim of this study is to assess whether the modified Sims position on the side of the fetal spine increases the rotation to occiput anterior position in women with epidural analgesia and a fetus in persistent occiput posterior (POP) position. METHODS: This is an open, randomized controlled, clinical trial...

OBJECTIVE: The purpose of this article is to review the imaging findings of necrotizing fasciitis as seen on radiograph, ultrasound, CT, and MRI, and to recognize the early findings in this potentially fatal disease. CONCLUSION: Although classically a clinical diagnosis, imaging is a powerful adjunct to facilitate early diagnosis in equivocal cases. Compared to plain radiography, US, CT and MR provide higher sensitivity and specificity for the diagnosis of necrotizing fasciitis...

OBJECTIVE: Ultrasound-guided biopsies are obtained generally to reach a sound diagnosis in the case of sonographically detectable hepatic changes. The most common and well-known complication associated with ultrasound-guided biopsies is haemorrhage after sampling, which may lead to the patient's death. The aim of this study was to evaluate a possible association between alterations in the coagulation parameters and sonographically observable haemorrhage following liver biopsies. MATERIALS AND METHODS: Dogs and cats in which an ultrasound-guided biopsy of the liver had been performed were retrospectively enrolled in the study...

Endoscopic ultrasound is increasingly being used for evaluation of pancreatic diseases and pancreatic tumors. Among various pancreatic cystic lesions, cystic degeneration of pancreatic neuroendocrine neoplasm is of the challenge in making diagnosis. Although unique characteristic of each type of pancreatic cystic lesions has been proposed abundantly, typical morphology of cystic degeneration of pancreatic neuroendocrine neoplasm is still unclear. We, herein, reported a case of 66-year-old woman who was incidentally found to have a cystic lesion in the tail of pancreas upon screening transabdominal ultrasonography...

OBJECTIVE: In distinguishing urate arthritis (UA) from non-crystal-related arthritides, joint sonography including the detection of the double contour sign (DCS) and hypervascularization using power Doppler ultrasound (PDUS) is an important step in the diagnostic process. But are these sonographic features equally reliable in every accessible joint under real-life conditions? METHODS: We retrospectively analyzed 362 patients with acute arthritis and evaluated the DCS and the degree of PDUS hypervascularization in patients with gout and in those with arthritis other than urate arthritis (non-UA)...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...
