Abstract
Listeria monocytogenes is associated with rhombencephalitis. However, the exact mechanisms of brainstem invasion remains poorly understood. Here, we demonstrate clinical and radiological data suggesting that Listeria may invade the brainstem via the trigeminal nerve. Three females (41, 64 and 70 years) with culture proven L. monocytogenes bacteremia and rhombencephalitis were investigated in the period of 2014-16. T2-weighted and contrast-enhanced T1-weighted MRI revealed a cerebellopontine abscess in all three patients, including the involvement of the trigeminal nerve root. In two patients, MRI also revealed selective contrast enhancement of the sensory trigeminal tract in the pons and medulla oblongata. Prior to any other neurological symptoms, two patients complained of hypoesthesia and a tingling sensation in the ipsilateral half of the face, consistent with sensory trigeminal nerve dysfunction on that side. In addition, we identified another 120 cases of Listeria rhombencephalitis following a systematic review. Cranial nerves VII, V, IX, and X, respectively, medulla oblongata, cerebellum and pons, were the most frequently involved brain structures. The present clinical and radiological findings corroborate earlier data from animal experiments, indicating that L. monocytogenes may be capable of retrograde intra-axonal migration along the cranial nerves. We suggest that in a subset of patients with rhombencephalitis L. monocytogenes enters the cerebellopontine angle through the trigeminal nerve, invading the brainstem via the sensory trigeminal nuclei.

Abstract
Many neurologic diseases can cause acute respiratory decompensation, therefore a familiarity with these diseases is critical for any clinician managing patients with respiratory dysfunction. In this article, we review the anatomy of the respiratory system, focusing on the neurologic control of respiration. We discuss general mechanisms by which diseases of the peripheral and central nervous systems can cause acute respiratory dysfunction, and review the neurologic diseases which can adversely affect respiration. Lastly, we discuss the diagnosis and general management of acute respiratory impairment due to neurologic disease.

Abstract
Failure of automatic involuntary respiration with preservation of voluntary respiratory drive (Ondine's curse) is a rare occurrence which has been reported following a variety of morphologic lesions near respiratory centers in the lower brainstem. We report the case of a 39-year-old woman with a syndrome of fulminant respiratory failure with features of Ondine's curse in whom neuropathologic examination disclosed a preexisting malformation of the lower brainstem, as well as acute local subarachnoid bleeding. Mechanisms in the present case are discussed and a review of similar cases published so far is given. The necessity of sound investigation, including neuropathologic studies in cases of sudden unexplained death, is underlined.

Abstract
UNLABELLED Central hypoventilation syndrome is defined as the failure of automatic control of breathing. Secondary central hypoventilation syndrome should distinguish from congenital central hypoventilation syndrome by brainstem abnormalities, place of respiratory control. CASE REPORTS We report two clinical cases characterized by late onset central hypoventilation syndrome (three years--six months, and five years old): in the first case the diagnosis was made after general anesthesia and the second one presented with acute nocturnal comatose state. Neuroradiologic investigations showed bilateral cerebral sinus veinous thrombosis without any brainstem lesions. Moreover these children had severe behavior disorders: psychomotor instability, alterations of social relations, language dysfunction, and neurocognitive deficit. This symptomatology seems independent from central hypoventilation syndrome and cerebral venous thrombosis. CONCLUSION Late onset central hypoventilation syndrome may be associated with cerebral venous thrombosis. Ischemia of central chemoreceptors or integration of their informations could be one of mechanism.

Abstract
We present a comprehensive review of sleep studies performed in patients with brain lesions complemented by 16 additional personal selected cases and by discussion of the corresponding animal data. The reader is cautioned about the risk of establishing an erroneous correlation between abnormal sleep and a given disorder due to the important inter and intra variability of sleep parameters among individuals. Salient points are stressed: the high frequency of post-stroke sleep breathing disorders is becoming increasingly recognised and may, in the near future, change the way this condition is managed. Meso-diencephalic bilateral infarcts induce a variable degree of damage to both waking and non-REM sleep networks producing and abnormal waking and sometimes a stage 1 hypersomnia reduced by modafinil or bromocriptine, which can be considered as a syndrome of cathecholaminergic deficiency. Central pontine lesions induce REM and non-REM sleep insomnia with bilateral lateral gaze paralysis. Bulbar stroke leads to frequent sleep breathing disorders. Polysomnography can help define the extent of involvement of various degenerative diseases. Fragmented sleep in Parkinson's disease may be preceded by REM sleep behavioural disorders. Multiple system atrophies are characterised by important sleep disorganization. Sleep waking disorganization and a specific ocular REM pattern are often seen in supra-nuclear ophtalmoplegia. In Alzheimer patients, sleep perturbations parallel the mental deterioration and are possibly related to cholinergic deficiency. Fronto-temporal dementia may be associated with an important decrease in REM sleep. Few narcoleptic syndromes are reported to be associated with a tumour of the third ventricle or a multiple sclerosis or to follow a brain trauma; all these cases raise the question whether this is a simple coincidence, a revelation of a latent narcolepsy or, as in non-DR16/DQ5 patients, a genuine symptomatic narcolepsy. Trypanosomiasis and the abnormal prion protein precociously after sleep patterns. Polysomnography is a precious tool for evaluating brain function provided it is realised under optimal conditions in stable patients and interpreted with caution. Several unpublished cases are presented: one case of pseudohypersomnia due to a bilateral thalamic infarct and corrected by modafinil, four probable late-onset autosomal recessive cerebellar ataxias without sleep pattern anomalies, six cases of fronto-temporal dementia with strong reduction in total sleep time and REMS percentage on the first polysomnographic night, one case of periodic hypersomnia associated with a Rathke's cleft cyst and four cases of suspected symptomatic narcolepsy with a DR16-DQ5 haplotype, three of which were post-traumatic without MRI anomalies, and one associated with multiple sclerosis exhibiting pontine hyper signals on MRI.

Abstract
Congenital central hypoventilation syndrome (CCHS) is a rare and unique condition that may prompt unparalleled approaches to the discovery of genes involved in development of cardiorespiratory control and gas exchange homeostasis. Its higher risk of recurrence in families and its association with Hirschsprung's disease suggest that an underlying genetic mechanism is involved. However, screening for mutations of the receptor tyrosine kinase RET and endothelin 3 has revealed only occasional patients affected by these mutations, therefore suggesting that CCHS may result from disruption of more than a single gene. In recent years, three principal issues have become apparent: 1) the autonomic nervous system is involved universally in CCHS cases, albeit to a varying extent; 2) the use of novel functional imaging approaches incorporating refined stimulus paradigms may provide essential research and clinical insights into localization and assessment of neural sites underlying the phenotypic expression of this syndrome; and 3) efforts to transition patients' nocturnal respiratory support to a noninvasive ventilatory modality should be critically evaluated and pursued, when appropriate, to improve the quality of life for patients and families.

Abstract
Ischemic lesions of the brainstem can lead to complex neurologic deficits. Failure of the automatic control of ventilation (Ondine's curse syndrome) is a possible but rare syndrome following localized brainstem dysfunction. We report on a 49-year-old man with intermittent bradycardia, cranial nerves' dysfunctions and a slight right-sided hemiparesis. An acute brainstem ischemia was diagnosed and treated immediately with high-dose heparin. Cerebral angiography revealed a proximal occlusion of the left vertebral artery but a normal right vertebral artery and a hyperplastic right posterior inferior cerebellar artery. Cranial Computed Tomography and MRI scan demonstrated multiple ischemic lesions in the posterior circulation. During a 4-week treatment course the patient underwent six episodes of acute severe hypoxia and hypercapnia requiring orotracheal intubation twice and manual ventilation by air mask over a few minutes for four times after a tracheostomy had been performed. Twice a short-term episode of hypothalamic Diabetes insipidus was observed following hypoventilation. We conclude that both Ondine's curse syndrome and diabetes insipidus were due to transient vertebrobasilar ischemia.

Abstract
Awareness of the existence of CCHS has led to increasingly frequent reports of such patients from all over the world. However, the exact pathophysiologic mechanisms underlying the clinical manifestations of this congenital disease entity remain unknown. For the respiratory physiologist, CCHS can be viewed as an experiment of nature that provides an important and unique window into central cardiorespiratory regulation. For the pediatrician, CCHS children represent an unique clinical challenge in coordinating the diagnostic and therapeutic procedures required to enhance the patients' quality of life.

Abstract
We present 2 cases of Listeria monocytogenes rhombencephalitis (L-RE), both affecting previously healthy adult men. Each of them developed a diphasic syndrome first characterized by fever, nausea and headache, followed, in a second phase, by severe brain stem dysfunction at the level of the pons, with meningism, multiple cranial nerve palsies, ataxia, and, in one case, seizures. The early examination of the cerebrospinal fluid (CSF) demonstrated the presence of Gram-positive bacilli whose typical characteristics were compatible with those of Listeria, allowing for immediate administration of a specific therapy. Neuroimaging techniques (either CT or MRI) did not provide any evidence of brain stem involvement, and they did not positively contribute to the diagnostic process. The immediate use of a specific antibiotic therapy led to a favourable clinical outcome for both patients.

Abstract
We report three cases of neuroborreliosis presenting with acute respiratory impairment. All the patients had encephalopathy and focal neurological signs with brain stem abnormalities in two. All three patients had respiratory arrest associated with progressive nocturnal hypoventilation or prolonged central apnoea. Tracheostomy and prolonged periods of ventilatory support were necessary in all cases and weaning was complicated by residual central respiratory disturbances. These cases emphasise that Borrelia infection should be considered in the differential diagnosis of unexplained respiratory failure.

Abstract
The cases of three full-term infant girls with both Hirschsprung's disease (HD) and Ondine's curse (OC) are presented, and the relevant literature is reviewed. All three patients required endotracheal intubation and assisted ventilation during the first 24 hours of life because of respiratory distress. The diagnosis of HD was subsequently established at age 13, 16, and 20 days, respectively. The aganglionic segment was confirmed to the rectum in one case, extended to the splenic flexure of the colon in the second case, and involved the terminal ileum in the third. The definitive treatment (endorectal pull-through) was completed successfully in all three patients, and the postoperative follow-up period was 3 to 34 months. All of them presently have tracheostomies and are maintained on home ventilation. They tolerate being off the ventilator while awake, and have nearly normal bowel habits and growth curves. Two have bilateral ciliary ganglion dysfunction, and one has strabismus. Based on this review, the authors conclude the following. (1) The incidence of the HD associated with OC may be more common than is generally believed (1.8% of all their HD patients have OC). (2) OC should be suspected in any newborn with HD who requires assisted ventilation in the absence of major cardiopulmonary abnormalities. Likewise, HD should be ruled out in any OC case with gastrointestinal dysfunction. (3) Contrary to the previous impression from the literature, the combination of OC and HD should not be considered fatal, because most such patients can be managed successfully and have a reasonable quality of life.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Listeria monocytogenes rhombencephalitis has never been studied in a significant group of patients. We describe 14 adult cases who were seen over a 10-year period. A biphasic illness was characteristic: (1) prodromes (5-15 days) with malaise, fatigue, headache, nausea or vomiting, and fever; (2) cranial nerve palsy with facial palsy, diplopia, dysphagia, dysarthria, usually multiple. Meningism and hemi- or tetraparesis were present in 11 patients and cerebellar dysfunction in 9 patients. In 4 cases, CT showed widening of the brain stem with disappearance of the surrounding cisterns. The cerebrospinal fluid was abnormal in all patients in whom this investigation was done (pleocytosis, elevation in protein content). The patients received antibiotic therapy for 2-6 weeks. In the 9 patients who recovered, the neurological dysfunction improved within 2 days to 1 week of the initiation of therapy. There were 5 deaths. At autopsy in 2 cases, there was severe purulent meningitis and rhombencephalitis with predominantly polymorphonuclear cellular infiltration in 1 case, while numerous microabscesses in the midbrain, pons and medulla were observed in the other. We conclude that L. monocytogenes infection should be considered in patients who develop fever and focal neurological signs particularly localized to the brain stem.

Abstract
The gram-positive bacterium Listeria monocytogenes is an ubiquitous, intracellular pathogen which has been implicated within the past decade as the causative organism in several outbreaks of foodborne disease. Listeriosis, with a mortality rate of about 24%, is found mainly among pregnant women, their fetuses, and immunocompromised persons, with symptoms of abortion, neonatal death, septicemia, and meningitis. Epidemiological investigations can make use of strain-typing procedures such as DNA restriction enzyme analysis or electrophoretic enzyme typing. The organism has a multifactorial virulence system, with the thiol-activated hemolysin, listeriolysin O, being identified as playing a crucial role in the organism's ability to multiply within host phagocytic cells and to spread from cell to cell. The organism occurs widely in food, with the highest incidences being found in meat, poultry, and seafood products. Improved methods for detecting and enumerating the organism in foodstuffs are now available, including those based on the use of monoclonal antibodies, DNA probes, or the polymerase chain reaction. As knowledge of the molecular and applied biology of L. monocytogenes increases, progress can be made in the prevention and control of human infection.

Abstract
We report clinicotopographic correlations in 2 patients with central hypoventilation and unilateral infarct in the caudal brainstem. One patient had nearly complete loss of ventilation involving both automatic and voluntary components. He showed no ventilator response during a CO2 retention test (PaCO2 62 mm Hg, PaO2 82 mm Hg), while consciousness was preserved until death. The infarct involved the reticular formation, nucleus tractus solitarius, nucleus ambiguus, and nucleus retroambiguus on the right but spared the dorsal motor nucleus of the tenth cranial nerve, and sensory and corticospinal tracts. The second patient showed hypoventilation more selectively involving automatic responses (Ondine's curse). The infarct involved the medullary reticular formation and nucleus ambiguus but spared the nucleus tractus solitarius. We suggest that unilateral involvement of pontomedullary reticular formation and nucleus ambiguus is sufficient for generating loss of automatic respiration, while associated lesion of the nucleus tractus solitarius may lead to more severe respiratory failure involving both automatic and voluntary responses.
