Bone age determination based on the study of the medial extremity of the clavicle
1998
The development of the medial clavicular epiphysis and its fusion with the clavicular shaft have been a subject of medical research since the second decade of this century. Computed tomography provides the imaging modality of choice in analyzing the maturation process of the sternal end of the clavicle. In a retrospective study, we analyzed normal development in 380 individuals under the age of 30 years. The appearance of an epiphyseal ossification center occurred between ages 11 and 22 years. Partial union was found from age 16 until age 26 years. Complete union was first noted at age 22 years and in 100 % of the sample at age 27 years. Based on these data, age-related standardized age dis…
Extradural Endoscopic Dissection of the Anterior Skull Base
1998
A study was conducted from February 29, 1996, to March 28, 1996, at the University of Brno's Pathology Institute in the Czech Republic to explore the possible application of craniofacial intracranial endoscopic techniques through minimal skin incisions and trephines in fresh cadavers (3 to 12 hours old). Through the trephines the dura was totally dissected from the bone. After this dissection a standard bicoronal incision and a full craniotomy was performed to assess the integrity of the meninges. This minimally invasive dissection of the skull base with the aid of an endoscope is characterized by fewer skin incisions, thereby avoiding the exposure of subcutaneous tissue, muscle, cranial bo…
Maternal coffee drinking in pregnancy and risk of small for gestational age birth
2005
Objective: We have analysed the association between coffee drinking before and during the three trimesters of pregnancy and risk of small for gestational age (SGA) birth. Methods: Cases were 555 women who delivered SGA births (ie <10th percentile according Italian standard). The controls included 1966 women who gave birth at term (≥37 weeks of gestation) to healthy infants of normal weight. Results: In comparison with nondrinkers, the ORs for SGA birth were 1.3 (95% confidence interval, CI, 0.9–1.9) for consumption of four or more cups of coffee/day before pregnancy, and 1.2 (95% CI 0.8–1.8), 1.2 (95% CI 0.8–1.8) and 0.9 (95% CI 0.6–1.4) for consumption of three or more cups of coffee/day d…
Abdominal scintigraphy for diagnosis of intestinal bleeding
1978
Abdominal scintigraphy with99mTc-pertechnetate, using a gamma-camera linked to a data processor, was done in 8 patients with acute massive intestinal hemorrhage and in 34 patients with chronic recurrent intestinal hemorrhage. Endoscopy and x-ray studies had failed in all patients to reveal a bleeding source. All but 3 patients underwent exploratory laparotomy, confirming the abnormal findings of scintigraphy. In all acutely bleeding patients, scintigraphy was positive. The bleeding was proven by laparotomy to be due to Meckel's diverticulum with gastric mucosa in 5, jejunal neurinoma in 1, and sigmoid colon carcinoma in 1 patient. Scintigraphy was positive in only 3 chronically bleeding pat…
Effect of per Capita Income on the Relationship between Periodontal Disease during Pregnancy and the Risk of Preterm Birth and Low Birth Weight Newbo…
2020
This work analyzed the available evidence in the scientific literature about the risk of preterm birth and/or giving birth to low birth weight newborns in pregnant women with periodontal disease. A systematic search was carried out in three databases for observational cohort studies that related periodontal disease in pregnant women with the risk of preterm delivery and/or low birth weight, and that gave their results in relative risk (RR) values. Eleven articles were found, meeting the inclusion criteria. Statistically significant values were obtained regarding the risk of preterm birth in pregnant women with periodontitis (RR = 1.67 (1.17–2.38), 95% confidence interval (CI)), and low birt…
Exposure to ambient air pollution during pregnancy and preterm birth: A Spanish multicenter birth cohort study
2016
Background and objective: Preterm birth is a major determinant of infant mortality and morbidity. Air pollution has been suggested as a risk factor for preterm delivery; however, the scientific evidence on this impact remains inconsistent. We assessed the association between residential exposure to air pollution during pregnancy and preterm birth (gestational age at delivery <37 weeks) in Spain. Methods: This study was based on 2409 pregnant women participating in the INMA birth cohorts in Asturias, Gipuzkoa, Sabadell and Valencia. Ambient levels of nitrogen dioxide (NO2) and benzene were estimated for each woman's residence for each trimester and for the whole pregnancy, using temporally a…
How is the adequacy of micronutrient intake assessed across Europe? A systematic literature review.
2009
EURopean micronutrient RECommendations Aligned is a network of excellence funded by the European commission, and established to address the problem of differences between countries in micronutrient recommendations as well as to understand how nutritional information including requirements and adequacy of intake is processed among different population groups. The aims of the present paper were to review the methods used for the adequacy assessment of the intake of six micronutrients of public health concern (vitamin A, folate, vitamin B12, Fe, Zn and iodine) in non-European and European nutrition surveys carried out on the apparently healthy population and to compare in particular the adequa…
Bed rest after embryo transfer negatively affects in vitro fertilization: a randomized controlled clinical trial.
2013
Objective To evaluate the influence of 10 minutes of bed rest after ET on the achievement of a live-born infant (LBI) in patients undergoing IVF treatment with oocyte donation (OD). Design Prospective, randomized, parallel assignment, controlled trial. Setting Private IVF center. Patient(s) A total of 240 patients undergoing a first IVF cycle with OD in our center. Intervention(s) Ten minutes of bed rest after ET or no bed rest, that is, allowing patients to ambulate immediately after the ET. Main Outcome Measure(s) The primary outcome was LBI rate per randomized patient. Secondary outcomes were implantation rate and biochemical and clinical miscarriage rates. Result(s) LBI rates (56.7% vs.…
Technical Note: Minimal Access Surgery for Cochlear Implantation with MED-EL Devices
2005
<i>Background:</i> Minimally invasive techniques have been described for cochlear implant surgery, but so far this had not been the case for Med-EL devices. <i>Objective:</i> To describe a newly developed minimal access approach for the implantation of Med-EL devices and report our results after up to 1 year of follow-up in 52 patients. <i>Discussion:</i> The use of a minimally invasive approach without raising a flap or extensive drilling of a bony well was feasible in all 52 patients of this series. It shortened the surgical time to an average of 45 min and there were no specific postoperative complications. The average follow-up of 8.4 months was uneve…
Early auditory evoked potentials: developmental aspects and validity in neuropaediatric and audiologic disorders.
1984
Auditory evoked potentials and in this context especially five waves in the first 10 ms (early auditory evoked potentials = EAEP) are a diagnostic aid in topodiagnosis of posterior fossa diseases. This is due to waves I to V which arise along the acoustic nerve and in brain stem structures such as medulla, pons and mid-brain. Besides an indication about the site of a lesion in the posterior fossa, wave V allows an objective threshold determination. The present results were gained in normal children aged 1-3 years and in children with neuropaediatric and audiologic disorders.
