Review
BACKGROUND
The International Classification of Sleep Disorders-Third Edition (ICSD-3) classifies catathrenia among the respiratory disorders and not as a parasomnia as in ICSD-2. Few patients have been reported during these years, and the clinical description of the sound is different from group to group. In fact, there is no full agreement about its nature, origin, meaning, and treatment.
METHODS AND RESULTS
In this paper we review the literature on catathrenia focusing on the characteristics of the sound, demographics of the patients, aetiology, response to treatment, etc., in order to support its classification as a respiratory disorder or a parasomnia. We also discuss the possibility of Catathrenia being not one disorder but two variants or two different disorders.

Review
Multiple respiratory abnormalities can be found in anxiety disorders, especially in panic disorder (PD). Individuals with PD experience unexpected panic attacks, characterized by anxiety and fear, resulting in a number of autonomic and respiratory symptoms. Respiratory stimulation is a common event during panic attacks. The respiratory abnormality most often reported in PD patients is increased CO2 sensitivity, which has given rise to the hypothesis of fundamental abnormalities in the physiological mechanisms that control breathing in PD. There is evidence that PD patients with dominant respiratory symptoms are more sensitive to respiratory tests than are those who do not manifest such symptoms, and that the former group constitutes a distinct subtype. Patients with PD tend to hyperventilate and to panic in response to respiratory stimulants such as CO2, triggering the activation of a hypersensitive fear network. Although respiratory physiology seems to remain normal in these subjects, recent evidence supports the idea that they present subclinical abnormalities in respiration and in other functions related to body homeostasis. The fear network, composed of the hippocampus, the medial prefrontal cortex, the amygdala and its brain stem projections, might be oversensitive in PD patients. This theory might explain why medication and cognitive-behavioral therapy are both clearly effective. Our aim was to review the relationship between respiration and PD, addressing the respiratory subtype of PD and the hyperventilation syndrome, with a focus on respiratory challenge tests, as well as on the current mechanistic concepts and the pharmacological implications of this relationship.

OBJECTIVE
We were to describe the clinical characteristics of late preterm and term newborn infants who needed invasive or non-invasive ventilation for respiratory distress but did not meet the diagnostic criteria of common neonatal respiratory disorders (atypical acute respiratory disorder; aRD).
METHODS
We retrospectively reviewed electronic medical records of 242 late preterm and term newborn infants born who were admitted to the neonatal intensive care unit for acute respiratory distress developed within 24 h after birth.
RESULTS
Newborn infants with aRD had significantly higher mean, maximum blood PCO2 levels and maximum FiO2 levels during the first 72 h after birth than infants with transient tachypnea of the newborn (TTN). Total periods of oxygen supplementation of the infants with aRD were significantly longer than those of infants with TTN, but shorter than those of the infants with meconium aspiration syndrome (MAS).
CONCLUSIONS
Except for definite diagnosis, higher oxygen need and PCO2 level on blood gas analysis during the initial period of their respiratory illness may be able to predict aRD, and these interventions may be able to decrease neonatal respiratory morbidity.

Review
Microparticles (MP) are plasmic membrane fragments released from cells after physiological stimulation or stress conditions like inflammation or infection. Their production is correlated to the rate of cell apoptosis. All types of cells can produce MP but they are produced mainly by platelets, endothelial cells, and leukocytes. They carry many bio-active molecules on their surface, specific to the parental cell, giving them the ability to be biomarkers and bio-effectors. MP are present in circulating blood, tissues and many biological fluids. Circulating MP levels can change during the course of many diseases. They have been the subject of many studies in the fields of cardiovascular disease and oncology. In the lungs, they are present in circulating blood and in the airways. They seem to have a role in pulmonary homeostasis in physiological situations and also in the expression of several disease processes. In this review of the literature, we were interested in the quantitative and qualitative variations in MP and their impact in airway diseases like chronic obstructive pulmonary disease (COPD) and asthma, pulmonary fibrosis and pulmonary hypertension.

Comparative Study Review
Regular physical activity is recognized as an effective health promotion measure. Among various activities, swimming is preferred by a large portion of the population. Although swimming is generally beneficial to a person's overall health, recent data suggest that it may also sometimes have detrimental effects on the respiratory system. Chemicals resulting from the interaction between chlorine and organic matter may be irritating to the respiratory tract and induce upper and lower respiratory symptoms, particularly in children, lifeguards and high-level swimmers. The prevalence of atopy, rhinitis, asthma and airway hyper-responsiveness is increased in elite swimmers compared with the general population. This may be related to the airway epithelial damage and increased nasal and lung permeability caused by the exposure to chlorine subproducts in indoor swimming pools, in association with airway inflammatory and remodelling processes. Currently, the recommended management of swimmers' respiratory disorders is similar to that of the general population, apart from the specific rules for the use of medications in elite athletes. Further studies are needed to better understand the mechanisms related to the development or worsening of respiratory disorders in recreational or competitive swimmers, to determine how we can optimize treatment and possibly help prevent the development of asthma.
