Delivery Induced Intraperitoneal Rupture of a Cystic Ovarian Teratoma and Associated Chronic Chemical Peritonitis

Intraperitoneal rupture of cystic ovarian teratoma is a rare complication. We report a case in a 29-year-old female, with increased abdominal circumference 2 months after vaginal delivery. MRI/CT raised this diagnosis associated to chemical peritonitis. A malignant ovarian mass with peritoneal carcinomatosis was excluded. Laparoscopic oophorectomy was performed and histologic analysis confirmed imaging findings. This case demonstrates the interest of imaging before surgery in pelvic masses to avoid misdiagnosing and to provide adequate treatment

Clinical predictors of radiographic abnormalities among infants with bronchiolitis in a paediatric emergency department

International audienceBackgroundAcute viral respiratory exacerbation is one of the most common conditions encountered in a paediatric emergency department (PED) during winter months. We aimed at defining clinical predictors of chest radiography prescription and radiographic abnormalities, among infants with bronchiolitis in a paediatric emergency department.MethodsWe conducted a prospective cohort study of children less than 2 years of age with clinical bronchiolitis, who presented for evaluation at the paediatric emergency department of an urban general hospital in France. Detailed information regarding historical features, examination findings, and management were collected. Clinical predictors of interest were explored in multivariate logistic regression models.ResultsAmong 410 chest radiographs blindly interpreted by two experts, 40 (9.7%) were considered as abnormal. Clinical predictors of chest radiography achievement were age (under three months), feeding difficulties, fever over 38°C, hypoxia under than 95% of oxygen saturation, respiratory distress, crackles, and bronchitis rales. Clinical predictors of radiographic abnormalities were fever and close to significance hypoxia and conjunctivitis.ConclusionOur study provides arguments for reducing chest radiographs in infants with bronchiolitis. For infants with clinical factors such as age less than three months, feeding difficulties, respiratory distress without hypoxia, isolated crackles or bronchitis rales, careful clinical follow-up should be provided instead of chest radiography

Accuracy of ultrasonography and magnetic resonance imaging in the diagnosis of placenta accreta.

PURPOSE: To evaluate the accuracy of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of placenta accreta and to define the most relevant specific ultrasound and MRI features that may predict placental invasion. MATERIAL AND METHODS: This study was approved by the institutional review board of the French College of Obstetricians and Gynecologists. We retrospectively reviewed the medical records of all patients referred for suspected placenta accreta to two university hospitals from 01/2001 to 05/2012. Our study population included 42 pregnant women who had been investigated by both ultrasonography and MRI. Ultrasound images and MRI were blindly reassessed for each case by 2 raters in order to score features that predict abnormal placental invasion. RESULTS: Sensitivity in the diagnosis of placenta accreta was 100% with ultrasound and 76.9% for MRI (P = 0.03). Specificity was 37.5% with ultrasonography and 50% for MRI (P = 0.6). The features of greatest sensitivity on ultrasonography were intraplacental lacunae and loss of the normal retroplacental clear space. Increased vascularization in the uterine serosa-bladder wall interface and vascularization perpendicular to the uterine wall had the best positive predictive value (92%). At MRI, uterine bulging had the best positive predictive value (85%) and its combination with the presence of dark intraplacental bands on T2-weighted images improved the predictive value to 90%. CONCLUSION: Ultrasound imaging is the mainstay of screening for placenta accreta. MRI appears to be complementary to ultrasonography, especially when there are few ultrasound signs

Stomach position versus liver-to-thoracic volume ratio in left-sided congenital diaphragmatic hernia

Objective: To describe a new grading method for stomach position (SP) in fetuses with left-sided congenital diaphragmatic hernia (L-CDH) using ultrasound and to correlate SP to liver position and to liver-to-thoracic cavity volume ratio (LiTR) using magnetic resonance imaging. Methods: SP were graded at the level of the 4-chamber view as following: grade 1-to-4 for stomach not visualised, visualised anteriorly at the apex of the heart, stomach showing abdominal structures anteriorly and stomach with its larger part posterior to the level of the atrial-ventricular heart valves, respectively. The LiTR was calculated and correlated to SP using the Mann-Whitney U test. Results: Seventy-four fetuses were included. Median LiTR for grade 1 SP was 0% and was not different from median LiTR for grade 2 SP (0%, p=NS). Median LiTR for grade 3 SP was 14.9% and was significantly higher than for grade 2 SP (p<0.001). Similarly, median LiTR for grade 4 SP was 20.7% and was significantly higher than for grade 3 SP (p<0.05). When SP was grade 1 or 2, liver was intra-abdominal in 21 (84%) out of 25 fetuses while it was always intrathoracic for SP 3 or 4. Conclusion: In L-CDH, SP as described represents a simple indirect measurement of intrathoracic position and quantification of liver.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
