RESUMO

UNLABELLED: Gossypiboma imaging features are not well known and are often confused with soft tissue tumours. Publications on this topic mainly consist of case reports and small cohorts. Its appearance on various imaging modalities is not well defined. This led us to carry out a review of literature to determine specifically: (1) which imaging modalities should be used in cases of suspected gossypiboma, (2) what are the most common imaging findings that contribute to the diagnosis of gossypiboma. An exhaustive review of literature was carried out in June 2015 in the Medline, PubMed and Cochrane databases using the keywords "gossypiboma/textiloma/foreign body". We found 205 articles describing one or multiple cases of gossypiboma in various locations. Of these, the 32 articles that had imaging data were chosen - 16 for the limbs and 16 for other locations. The type of imaging carried out, description of the gossypiboma and circumstances of the discovery and occurrence were recorded. Descriptive statistics were generated to define the type of imaging used and the various findings. Imaging consisted of X-rays in 21/32 cases (66%), computed tomography (CT) in 14/32 cases (43%), magnetic resonance imaging (MRI) in 21/32 cases (65%) and ultrasonography in 14/32 cases (43%). On X-rays, bone involvement was found in 9/15 cases (60%); there was peripheral contrast product uptake on the CT scans in 9/14 cases (64%), a hypointense signal on T1-weighted sequences on MRI in 6/13 cases (46%) and lack of vascularisation in 8/13 cases (62%) and a acoustic shadow on ultrasonography in 9/14 cases (64%). In a patient presenting with a soft tissue lump and history of surgery, an imaging work-up including X-rays, ultrasonography and MRI must be performed. Bone involvement on X-rays, acoustic shadowing on ultrasonography and hypointense signal on T1-weighted MRI sequences with lack of vascularisation in combination with a history of surgery can bring up the possibility of gossypiboma. If there is a possibility of soft tissue tumour, the case should be discussed in a multidisciplinary meeting and a biopsy should be performed first. LEVEL OF EVIDENCE: IV - systematic analysis of published retrospective studies.

RESUMO

We report the experimental measurement of Ramsey interference fringes in the single-photon excitation to a high-lying bound state of atomic argon by pairs of phase-locked, time-delayed, extreme UV high-order-harmonic pulses at 87 nm. High-visibility Ramsey fringes are observed for delays larger than 100 ps, thus demonstrating a potential resolving power >10(5) at this wavelength.

RESUMO

We report on an infant with multi-system disease including liver fibrosis, right microphthalmia with cataract, interstitial pneumonitis, and hyperechoic lesions in the basal ganglia and in the periventricular and thalamic regions. Prenatal ascites with hepatomegaly concomitantly with detection of cytomegalovirus (CMV) DNA in the amniotic fluid, following recurrent maternal CMV infection, had been shown. Although CMV culture and DNA detection were negative in the urine, the infant was given foscarnet because CMV infection was demonstrated in the liver by DNA detection and immunohistochemical staining. Favorable clinical outcome and absence of CMV in the liver were subsequently shown. Our case suggests that congenital CMV disease following maternal recurrence may not be associated with disseminated infection but only with intracellular infection. The diagnosis should therefore be based on CMV detection in the involved organs. Moreover, this is the first report on the possible efficacy and safety of foscarnet for therapy of immunocompetent infants with congenital CMV disease.

RESUMO

OBJECTIVE: To study the use of a modification of the classical biophysical profile by the combination of computerized analysis of fetal heart rate (cCTG) and the amniotic fluid index (AFI) in the prediction of neonatal acidemia at birth. METHODS: We considered 89 singleton third trimester high risk pregnancies delivered by cesarean section, with an AFI evaluated within 24 hrs from birth, and an antepartum cCTG performed within 6 hrs from delivery. We assigned values for AFI (oligo/anhydramnios = 1, normal = 0) and cCTG (Dawes-Redman criteria, not satisfied = 1, satisfied = 0). The endpoint was to predict an abnormal neonatal outcome as defined by an umbilical artery (UA) pH < or = 7.2. RESULTS: Fifteen neonates presented an UA pH < or = 7.2. By performing a logistic regression, we found that cCTG + AFI score (abnormal value 1-2) was able to significantly predict a pH value (< or = 7.20) with an Odds Ratio = 2.83 (p < 0.02). The diagnostic accuracy of the combination of cCTG + AFI was as follows: sensitivity: 80%, specificity: 58%. COMMENT: We suggest that the combination of cCTG + AFI included in the simple score we propose, may be of value in the prediction of neonatal acidemia and help in the management of third trimester high risk pregnancies.

RESUMO

OBJECTIVE: The aim of this study was to correlate antepartum computerized cardiotocography (cCTG) and Doppler velocimetry parameters to umbilical blood gas analysis (UBGA) value and Apgar score 1-5 min as neonatal outcome endpoints. METHODS: Forty-eight third trimester single high risk pregnancies were considered for this study, with a cCTG performed within 24 hrs from delivery, a complete Doppler velocimetry study performed within 48 hrs from delivery and an UBGA evaluation at birth and before the first breath. RESULTS: When we analyzed the backward stepwise regression of each Doppler velocimetry and cCTG parameters versus UBGA parameters as dependent variables, we found that the linear combination of fetal heart rate (FHR) (p < 0.001), high variation episodes in min (HV) (p < 0.01) and low variation episodes in msec (LV) (p < 0.03) was able to predict pO2 values. When performing a logistic regression of data for every single parameter of FHR tracing and Doppler velocimetry against pH < 7.2 and Becf < -4 as endpoints, we found that only umbilical artery pulsatility index (UA PI) was able to predict umbilical artery pH (O.R.: 8.1 [1.07-61.8]) and only fetal movements (FM) from FHR tracing values was able to predict UA pH (O.R.: 0.94 [0.89-0.99]). Further analysis considers a cut-off for the prediction of UA pH < 7.2 at birth a value at > or = 1.35 for UA PI and at < or = 12 for FM/h. The combination of UA PI > 1.35 and FM/h < 12 did not improve the ability to predict acidemia at birth. CONCLUSION: The validity of our data from the clinical point of view suggests that in third trimester high risk pregnancies, an UA PI > or = 1.35 and/or FM/h < or = 12 (in a FHR tracing > or = 40 min) may represent a risk of 70% acidemia in neonates.

RESUMO

OBJECTIVE: Administration of cytomegalovirus (CMV)-specific immunoglobulins to pregnant women with primary CMV infection in order to inhibit viral activity. MATERIALS AND METHODS: We considered 2 groups of patients including 24 pregnant women. GROUP A: 12 women with primary maternal-fetal CMV infection, shown by CMV culture and CMV DNA detection in 9 (75%) and by only CMV DNA detection in 3 (25%) of the amniotic fluid (AF) samples. These pregnant women were treated with infusions of CMV-specific immunoglobulins (200 U/Kg of maternal weight and 400 U/Kg of fetal weight to prevent CMV pneumonia and gastroenteritis). As control group we considered 15 pregnant women, 5 of whom had CMV-positive AF samples demonstrated by polymerase chain reaction (PCR) and 10 also by CMV culture. GROUP B: 12 women with primary CMV infection, who were treated with monthly infusions of specific immunoglobulins to prevent the transmission of CMV to the fetus. In the control group we followed up 53 patients who were not treated, including 15 subjects with CMV-positive AF samples, 20 with CMV-negative AF samples and 18 women who did not accept amniocentesis. GROUP A: All 9 neonates born to mothers with culture and DNA positive AF samples were CMV infected. On the contrary, the babies born to 3 women with only PCR-positive amniotic fluid were CMV-negative by culture and DNA detection. Of 9 neonates infected, 8 were asymptomatic and 3 became culture-negative before they were one year old. The only symptomatic baby (IUGR and ventriculomegaly diagnosed by ultrasound during the pregnancy) was treated with ganciclovir and foscarnet. Of 15 non-treated patients, 11 had ultrasound signs of placental and/or fetal CMV involvement. Seven of these (46%) aborted and 4 (27%) delivered neonates with severe symptomatic infection. The other 4 patients delivered oligo-symptomatic CMV infected neonates positive by culture or PCR only. Overall, the prevalence of symptomatically infected neonates or fetuses was significantly higher (p = 0.02) among non-treated than treated women. Moreover, the babies of treated women showed less prolonged (p = 0.01) viruria than those of non-treated patients. GROUP B: all 11 pregnant women, treated with immunoglobulins delivered CMV-negative neonates. One patient, who had interrupted infusions at the 24th gestation week, delivered an asymptomatic CMV infected baby. In the control group, 4 women with CMV-negative AF samples delivered neonates with asymptomatic infection. Of 18 patients who did not undergo amniocentesis, 9 (50%) aborted; of remaining 9 women, 3 (33%) delivered CMV infected neonates. CONCLUSIONS: Our data suggest that CMV immunoglobulins may be effective for treatment or prevention of fetal CMV infection.
