Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays.

2021

Abstract Background Button battery ingestions have emerged as an increasing medical issue in recent years, especially for children. The frequent use of these energy sources in small appliances and toys is responsible for their ubiquitous occurrence in households. In addition to other possible foreign bodies, button batteries are particularly dangerous as they can cause severe complications in the aerodigestive tract. Objective The study aimed for a detailed analysis of specific radiographic identifiers of button batteries and similarly configured potential esophageal foreign bodies in high-resolution X-ray scans. Methods A selection of potentially hazardous button batteries - in cases of in…

Metabolic adaptation and neuroprotection differ in the retina and choroid in a piglet model of acute postnatal hypoxia.

2013

Hypoxic-ischemic insults to the neonatal brain may cause neurodevelopmental disorders. Vulnerability of different areas of the neural tissue to hypoxic-ischemic stress might be explained by either heterogeneous sensitivity to oxygen or neuroprotective capability. Our understanding of regional heterogeneity is still incomplete in terms of metabolic reconfiguration and/or activation of neuroprotective mechanisms.We studied, by western blotting, reverse-transcriptase PCR, and tandem mass spectrometry, the response of retina and choroid at protein, gene, and metabolic levels during hypoxia in a piglet model of acute postnatal hypoxia.We evidenced a metabolic shift towards glycolysis in choroid …

Comparing Aachen Minipigs and Pietrain Piglets as Models of Experimental Pediatric Urology to Human Reference Data

2020

<b><i>Introduction:</i></b> Swine had special roles in the development of minimally invasive procedures to treat vesicoureteral reflux, and minipigs have been gaining ground in recent years in experimental pediatric urology as they combine small size with less vulnerable adult physiology, but their suitability as a model has never been assessed. We therefore compared a landrace piglet with a juvenile minipig to elucidate comparability. <b><i>Methods:</i></b> We evaluated five 3-week old Pietrain piglets and five 3-month old Aachen Minipigs as representatives of landrace and minipig models based on their expected bodyweight being similar to a n…

Umbilical artery blood flow velocity waveforms during variable decelerations of the fetal heart rate

1991

Blood flow velocities of the umbilical arteries were measured by Doppler ultrasonography during variable decelerations of the fetal heart rate. The flow velocity waveforms, being normal between uterine contractions, showed either an unchanged flow velocity waveform with an exclusive fetal heart rate effect on end-diastolic velocities or a rapid change to absent and reverse diastolic flow during the decelerations, indicating an abrupt increase in placental resistance with a halt in placental perfusion. Computer-aided reconstruction of the fetal heart rate curve revealed the exact temporal relationship between the reduction of umbilical artery perfusion and deceleration of fetal heart rate. W…

Predictors of testicular viability in testicular torsion

2007

Abstract Aim Testicular torsion (TT) requires prompt diagnosis and treatment to avoid testicular loss. Most studies have focused on the ideal work up to rule TT out in cases of acute scrotum. We attempted here to define objective criteria to select between orchidopexy and orchidectomy in patients undergoing surgery for TT. Patients and methods Fifteen boys with a median age at presentation of 7.8 (range 6.4–12) years undergoing surgical treatment for TT underwent color-Doppler ultrasound (CDU) preoperatively, and a bleeding test intraoperatively. Duration of preoperative history, degree of torsion, CDU findings and degree of bleeding were analyzed. Results Salvageability was independent of …

Posterior variant of alien limb syndrome with sudden clinical onset as self-hitting associated with thalamic stroke

2020

We present a case of sudden postischaemic onset of alien limb syndrome, with unintentional self-injury. Alien limb syndrome is an uncommon neurological disorder featured by uncontrolled and involuntary movements of a limb. Three variants of alien limb syndrome have been described: the anterior, featured by grasping of surrounding objects, the callosal, presenting with intermanual conflict, and the posterior, associated with involuntary levitation of the limb. Our patient suffered from an acute presentation of the posterior variant of the alien limb syndrome, resulting from an isolated thalamic stroke which was documented using 24-h computed tomography brain scan. Only one previous case of a…

Menopause symptom management in women with dyslipidemias: An EMAS clinical guide.

2020

Abstract Introduction Dyslipidemias are common and increase the risk of cardiovascular disease. The menopause transition is associated with an atherogenic lipid profile, with an increase in the concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), apolipoprotein B (apoB) and potentially lipoprotein (a) [Lp(a)], and a decrease in the concentration of high-density lipoprotein cholesterol (HDL-C). Aim The aim of this clinical guide is to provide an evidence-based approach to management of menopausal symptoms and dyslipidemia in postmenopausal women. The guide evaluates the effects on the lipid profile both of menopausal hormone therapy an…

Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment.

2016

Long-term outcomes are of special concern in children after urinary diversion. In a single institution study we evaluated retrospectively the long-term outcomes of urinary diversion in children, in whom the ileocecal segment had been used, in respect to complications of the efferent segment.The Mainz pouch was used in 107 children for continent urinary diversion. Indications were neurogenic bladder (53%, 57/107), exstrophy-epispadias complex (25%, 27/107), malignancy (13%, 14/107), and others (9%, 9/107). Continent cutaneous diversion was performed in 95 patients, and 12 patients received bladder augmentation/substitution with a continent cutaneous stoma. As efferent segment, we used the in…

Endometrial carcinoma and its precursors: Early detection and treatment

1990

Endometrial carcinoma is the most frequent genital neoplasia in women. Precursors of this condition include endometrial hyperplasia, particularly when cytologic atypia occurs. Among the frequent early clinical manifestations of endometrial carcinoma is abnormal uterine bleeding that must be differentiated from bleeding associated with benign conditions. Early detection of endometrial carcinoma and its precursors in women at risk is the best prophylactic measure in the final therapeutic outcome. In this review, the accuracy of methods of early diagnosis of endometrial carcinoma and its precursors is assessed, in order to provide early therapy and optimum prognosis. The epidemiology of endome…
