Optic disc drusen in tilted disc
2017
Purpose To investigate if a congenital anomaly of the head of the optic nerve like such as tilted disc can be a risk factor for the development of optic disc drusen. Methods The study was performed retrospectively on the files of 47 patients with optic disc drusen. The diagnosis was confirmed by fluorescein angiography and B-scan ultrasonography. The authors examined the fundus photographs and the fluorescein angiographies of these patients looking for the presence of tilted discs. Results Two of the 47 patients with optic nerve drusen had tilted discs as well, about twice the expected rate. Both cases presented a parapapillary hemorrhage. Conclusions The concomitant presence of tilted disc…
One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation
2016
Objective To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child. Design Part of an observational study. Setting University teaching hospital. Patient(s) Twenty eight-year-old woman with uterine agenesis, her male partner, and her 50-year-old mother. Intervention(s) In vitro fertilization with embryo cryopreservation before live donor uterus transplantation (UTx). Induction immunosuppression. Embryo transfer 12 months after UTx, pregnancy controls, delivery, and hysterectomy. Main Outcome Measure(s) Results of IVF-ET, parameters of pregnancy/birth, and surgical d…
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.
Massive triiodothyronine intoxication: Efficacy of hemoperfusion?
2002
A case of massive accidental triiodothyronine intoxication (1000-fold the usual therapeutic dose, for 8 days) is reported with important disturbances of cardiovascular and central nervous systems that required intensive care support. Serum free triiodothyronine levels were 4789 pmol L-1 on admittance (normal values, 3.5-6.5 pmol L-1). In the absence of a specific treatment, hemoperfusions were performed but failed to accelerate significantly the decay of blood levels of free triiodothyronine (apparent half-life 25.9 hours; 95% confidence interval: 19.8-37.4 hours). The patient, a young woman, made a satisfactory recovery, in spite of important clinical complications.
Experts' assessment of probability and level of pesticide exposure in agricultural workers.
2000
The occupational history of the parents of 261 infants with congenital malformations and 261 matched controls was collected. During the relevant time period before the birth of their child, 183 parents were involved in agricultural activities, 49% of them having directly applied pesticides. Two experts assessed the probability and the level of exposure to each quoted pesticide (582 observations) by using 4-point scales. Interrater agreement was estimated. Kappa-weighted values for probability and level of exposure were, respectively, kappa = 0.36 and kappa = 0.39. In the analysis of some categories of exposure (non-applicators, herbicides) very low interrater agreement was observed. In epid…
Early detection of embryonic malformations by transvaginal and color Doppler sonography.
1994
A total of 834 women with uneventful pregnancies were followed prospectively until the 15th week of gestation by TVS to screen for early embryonic malformations. Twenty-eight embryonic anomalies were detected in this series (3.3%). The median gestational age at diagnosis was 11 (range, 8 to 15) weeks. Two neural tube defects were missed by early TVS screening. Two suspected abdominal wall defects were not confirmed by repeat mid-second trimester abdominal sonography representing 6.7% of all fetal malformations evident by 24 weeks of gestation. The sensitivity and specificity of TVS screening for fetal malformations in this series were 93.3 and 99.7%, respectively. In addition, the role of T…
An unusual case of sudden cardiac death during sexual intercourse
2018
The most common cause of sudden death during sexual intercourse in adults is heart disease, and it is usually the male, whereas the death of the woman is unusual. Generally, in these cases, death occurs as a result of cardiovascular disease. The authors report an unusual case of the sudden death of a young woman during sexual intercourse. The post-mortem investigations (autopsy, cardiac nuclear magnetic resonance and cardiac histology) demonstrated a previously undiagnosed arrhythmogenic right ventricular cardiomyopathy. The terminal cause of death was a malignant arrhythmia from arrhythmogenic right ventricular cardiomyopathy. This is the first report of a case in which sexual activity ca…

Bickerstaff brainstem encephalitis. A case report
1992
A 33-year-old woman three weeks after a febrile illness presented with a syndrome of ophthalmoplegia, ataxia and areflexia (SOAA) that characterizes clinically both Bickerstaff and Miller Fisher syndromes. The normality of the electrophysiological tests performed, the CSF findings and the magnetic resonance images proved that the syndrome stemmed from brainstem pathology.
Coffee drinking and risk of preterm birth
2006
Objectives: We analysed the association between coffee drinking before and during the three trimesters of pregnancy and the risk of preterm birth of babies normal for gestational age (NGA) or small for gestational age (SGA). Methods: Case-control study conducted in University clinics of North Italy. Cases were 502 women who delivered at < weeks of gestation. The controls included 1966 women who gave birth at term (≥37 weeks of gestation) to healthy infants on randomly selected days at the hospitals where cases had been identified. Results: There was inverse association for coffee consumption in the third trimester of pregnancy in SGA cases compared to NGA (heterogeneity test between OR: χ12…
