BACKGROUND: Abdominal pain is one of the most common chief complaints of patients presenting to emergency departments, and emergency physicians (EPs) often evaluate patients with right lower quadrant abdominal pain. Ovarian torsion is a rare cause of abdominal pain, but early diagnosis is essential for salvage of the affected ovary. The diagnostic study of choice for ovarian torsion is a pelvic ultrasound with color Doppler, but it is important for EPs and radiologists to be aware of findings of ovarian torsion that might appear on computed tomography (CT)...

Arterial thrombosis of the newborn is rare and associated with poor prognosis, often attributed to umbilical arterial catheterization. The aortic and spontaneous forms are exceptional. Its severity requires fast and effective treatment. Although therapeutic means are numerous, no consensus has been established to date although thrombolysis and heparin therapy appear to give good results depending on the site and extent of thrombosis. We report a case of extensive thrombosis of the abdominal aorta in a 5-day-old newborn, revealed by acute hypernatremic dehydration...

By consensus, late fetal growth restriction is that diagnosed >32 weeks. This condition is mildly associated with a higher risk of perinatal hypoxic events and suboptimal neurodevelopment. Histologically, it is characterized by the presence of uteroplacental vascular lesions (especially infarcts), although the incidence of such lesions is lower than in preterm fetal growth restriction. Screening procedures for fetal growth restriction need to identify small babies and then differentiate between those who are healthy and those who are pathologically small...

REVIEW
Liran Hiersch, Nir Melamed
Fetal growth restriction implies failure of a fetus to meet its growth potential and is associated with increased perinatal mortality and morbidity. Therefore, antenatal detection of fetal growth restriction is of major importance in an attempt to deliver improved clinical outcomes. The most commonly used approach towards screening for fetal growth restriction is by means of sonographic fetal weight estimation, to detect fetuses small for gestational age, defined by an estimated fetal weight <10th percentile for gestational age...

The goals of the study described here were to evaluate the feasibility and reproducibility of measuring spleen stiffness (SS) using point shear wave elastography in a series of cirrhotic patients and to investigate whether SS, liver stiffness (LS) and other non-invasive parameters are correlated with the presence of esophagogastric varices (EVs). Fifty-four cirrhotic patients with low-grade EVs or without EVs at esophago-gastro-duodenoscopy were enrolled. They underwent abdominal ultrasound and Doppler ultrasound of hepatic vessels simultaneously with p-SWE of the liver and spleen...

A spectrum of vascular complications can be seen in pediatric liver transplant patients, including occlusion and hemodynamically significant narrowing of the vessels that provide inflow to or outflow from the graft. Intraoperative Doppler ultrasound (US) has the potential benefit of identifying vascular complications in pediatric liver transplant patients prior to abdominal closure. Importantly, intraoperative Doppler US can be used as a problem-solving tool in situations such as position-dependent kinking of the portal or hepatic veins, or in suspected vasospasm of the hepatic artery...

Borderline tumors have a histological aspect of atypical epithelial proliferation without stromal invasion and typically occur in fertile ages, approximately one-third of women diagnosed are younger than 40. Serous borderline tumors are the most encountered and they can present micropapillary features that are associated with a higher rate of recurrence and the possibility of peritoneal implants. We present the case of a serous borderline ovarian tumor in a young patient and the diagnosis and treatment particularities...

Superior mesenteric artery (SMA) syndrome is one of the rare causes of small bowel obstruction. It develops following a marked decrease in the angle between SMA and the abdominal aorta due to weight loss, anatomical anomalies, or following surgeries. Nutcracker syndrome in the left renal vein may also occur following a decrease in the aortomesenteric angle. Though SMA syndrome and renal nutcracker syndrome share the same pathogenesis, concurrent development has rarely been reported. Herein, we report a 23-year-old healthy male diagnosed with SMA syndrome and renal nutcracker syndrome due to severe weight reduction...

Ewing's sarcoma/primitive neuroectodermal tumor (EWS/PNET) in the kidney is a rare but high-grade malignant tumor that affects predominantly elder children and adolescents. Patients mostly present with nonspecific symptoms such as abdominal pain and gross hematuria. Since EWS/PNET has a rapid clinical progression with early metastasis and death, it is essential to make an accurate and early diagnosis. Once diagnosed, multimodality treatment, including radical surgery combined with adjuvant chemotherapy, and radiotherapy if necessary, is recommended...
