Moro reflex

Pulmonary aspiration of gastric contents, despite its infrequent occurrence, demands special preventive care. Decreased oesophageal sphincter function and protective airway reflexes caused by depression of consciousness, predispose patients to this severe complication. Recently developed preoperative fasting guidelines suggest shorter fasting periods, especially for liquids, providing more comfort to patients and less risk of hypoglycemia and dehydration, without increasing incidence of perioperative pulmonary aspiration...

BACKGROUND AND OBJECTIVES: Despite its low incidence, aspiration of pulmonary gastric contents may have devastating consequences. Esophageal sphincter function and protective airway reflexes decrease caused by conscience depression, predisposes patients to this severe complication. This article is a review of physiological aspects associated to gastroesophageal reflux, as well as of the methods to prevent it. CONTENTS: Comments are made about the mechanisms involved in gastric contents aspiration, its consequences and preventive methods, including recent preoperative fasting guidelines developed after review of the literature, the reasonable use of drugs acting on gastric pH and volume, and finally the effects of different airway control methods on pulmonary aspiration prevention...

INTRODUCTION: Maturity is a complex functional condition influenced especially by the development of the vital functions of a fetus, primarily by the degree of the development of its central nervous system. The aim of this investigation was to establish the gestational maturity of the nervous system by neurosonography and neurological status. MATERIAL AND METHODS: The parameter of the neurological maturity, compared in this research are a neurological status and the degree of girification established by the ultrasound...

We describe a term baby girl with (CHARGE syndrome coloboma, heart anomaly, choanal atresia, retardation, and genital and ear anomalies association) who had persistent complete absence of the Moro reflex but preservation of other primary neonatal reflexes. A computed tomography scan revealed bilateral absence of the semicircular canals and hypoplastic vestibules. We suggest that isolated absence of the Moro reflex may reflect underlying abnormalities of the vestibular system and may, therefore, not necessarily be associated with a generalized disturbance of the central nervous system as is usually the case...

The recovery of visual performance and pupil responses were investigated in patients with demyelinating optic neuritis (ON) and multiple sclerosis (MS). The pupil constriction amplitude and the time delay (latency) of the pupil response were measured in 14 patients with a history of unilateral ON in response to either achromatic (luminance) or chromatic (isoluminant) stimulus modulation. Five of these subjects were diagnosed later with MS. In addition, we measured detection thresholds for achromatic stimuli using standard visual field perimetry and chromatic thresholds using a new colour assessment and diagnosis (CAD) test that isolates the use of colour signals...

The existence of a functional interplay between alpha(2)-adrenoceptor and opioid receptor inhibitory pathways modulating neurotransmitter release has been demonstrated in the enteric nervous system by development of sensitivity changes to alpha(2)-adrenoceptor, mu- and kappa-opioid receptor agents on enteric cholinergic neurons after chronic sympathetic denervation. In the present study, to further examine this hypothesis we evaluated whether manipulation of alpha(2)-adrenoceptor pathways by chronic treatment with the antidepressant drug, desipramine (10 mg/kg i...

UNLABELLED: A non-controlled, prognostic cohort study was performed with the aim of establishing markers of neurological development and defining a clinical and epidemiological profile of preterm newborns at 3, 6, 9, and 12 months of gestation-corrected age in terms of primitive reflexes evolution. RESULTS: At 3 months old of corrected age, all primitive reflexes were present. At 6 months old, all children showed plantar grasp and 2.7% still showed Moro and palmar grasp...

Ernst Moro was born on December 8, 1874, in Ljubljana, the capital of Slovenia, then part of the Austro-Hungarian empire and attended university in Graz, Austria. Pediatrics, initially regarded as a part of internal medicine, was in its early days as an independent field at universities in German-speaking Europe. The first Chair of Pediatrics had been established in Vienna, Austria in 1884. Ten years later Germany was granted its first Chair in Berlin. Escherich, who held the first Chair of Pediatrics at Graz, was seen as one of the most respected pediatricians in Europe...

I report the case of an infant girl who was exposed to lithium during gestation and her follow-up at the age of 1 year. She presented with transient neurodevelopmental deficits including lethargy, hypotonia, and poor oral feeding ability in the neonatal period. She required supportive treatment and made gradual improvement in neurologic functioning. On examination at the age of 1 year, physical findings and psychomotor development were normal. The English literature from 1978 to 2004 is reviewed. A total of 30 patients who were exposed to lithium during gestation with adequate clinical description were identified...

Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is being evaluated as a potential new therapy for patients with Huntington's disease (HD). In addition to skeletal movement disorders, HD patients have difficulty initiating voluntary saccades and have difficulty in suppressing rapid saccades toward newly appearing stimuli. We measured several saccade parameters in an HD patient who had marked improvement of clinical symptoms with bilateral GPi DBS to determine whether oculomotor performance improved in parallel with clinical scores...

OBJECTIVE: The pupil response to light flux increments is abnormal in severe optic neuritis, but little is known about the effects of this condition on the pupil colour response. The aim of this study was to examine how optic neuritis affects pupil responses to light flux and colour modulation and the extent to which such pupil responses mirror the loss and recovery of vision. METHODS: A new pupil examination technique that makes use of sinusoidal modulation of either luminance contrast or chromatic saturation was employed...

AIM: To investigate whether the same behavioral patterns were present pre- and postnatally, and whether there were any differences in the frequency of movements observed in fetal and in early neonatal life. SUBJECTS AND METHODS: Ten out of 37 pregnant women in the third trimester of pregnancy (median gestational age 34 weeks, range 33 to 35 weeks) in the two-month period (from November 1st to December 31st, 2003) were enrolled in the investigation. Ten term, appropriate for gestational age newborns (seven born vaginally, three by elective SC, six girls, six first-born) and were enrolled in the study...

The primitive reflexes and the postural reactions comprise one of the earliest, simplest, and most frequently used tools among child neurologists to assess the central nervous system integrity of infants and young children. Infants with cerebral palsy have been known to manifest persistence or delay in the disappearance of primitive reflexes and pathologic or absent postural reactions. The clinical significance of asymmetric tonic neck reflex, Moro, palmar grasp, plantar grasp, Galant, Babinski, Rossolimo, crossed extensor, suprapubic extensor, and heel reflex, alone or in combination, as well as their contribution to the early diagnosis and differential diagnosis of cerebral palsy, have been demonstrated in a number of studies...
