Short term, sublethal changes in coughing rate, cardiac and ventilatory frequencies in hatchery-reared rainbow trout (27-34 cm) exposed to menazon and gamma BHC containing pesticide were monitored at 15 +/- 1 degree C during recovery period to investigate the effects of this chemical on fish respiratory and cardiovascular systems. Laboratory conditions simulated a rapid environmental pollution often occurring in running waters. The coughing response was particularly sensitive to water pollutants. Average rate of ventilation was lower in treated fish than in control specimens and decreased parallel with the time of recovery. Average heart rate was higher in treated trout as compared to the controls. These changes were characteristic for hypoxic conditions and provide useful sublethal physiological indications for a rapid environmental stress. Percentage coupling and phase angle of ECGs within the ventilatory cycle were also studied during recovery when significant differences were observed between treated and untreated groups of fish.

Lung diseases associated with surfactant metabolism disorders represent a significant but heterogeneous group of rare disorders. Intra-alveolar accumulation of protein related to surfactant dysfunction leads to cough, hypoxemia and radiological diffuse infiltration. Inherited deficiency of pulmonary surfactant protein B (SP-B) was initially described in term newborns who develop severe respiratory failure at birth. More recently, mutations in surfactant protein C (SP-C) or in proteins required for surfactant synthesis such as ATP-binding cassette, sub-family A, member 3 (ABCA3) or NK2 homeobox 1 (NKX2-1) were identified in newborns with respiratory distress but also in children with diffuse infiltrative pneumonia. The aim of this review is to describe the clinical presentation of these diseases but also the diagnostic tools and the treatments options available.

Pulmonary surfactant is a unique mixture of lipids and specific proteins that reduces surface tension at the air-liquid interface, preventing collapse of the lung at the end of expiration. Recessive loss-of-function mutations of pulmonary surfactant protein B (SP-B) was initially described in infants who develop respiratory failure at birth. More recently, mutations in other constitutive surfactant proteins like surfactant protein C or implied in its metabolism like ATP-binding cassette, sub-family A, member 3 (ABCA3) or NK2 homeobox (NKX2-1) were identified in newborn with respiratory distress but also in children with diffuse infiltrative pneumonia. Intra-alveolar accumulation of protein related to surfactant dysfunction leads to cough, hypoxemia and radiological abnormalities including ground-glass opacities and lung cysts. The clinical and radiological features associated with these genetic disorders, along with their treatment and outcome, are reviewed.

Vaping's popularity has grown exponentially since its introduction to the US market in 2003. Its use has sky-rocketed since the unveiling of the vaping pods in 2017 which may account for the advent of the vaping related illnesses we are now seeing. Substances such as nicotine solution, tetrahydrocannabinol (THC) oil, cannabidiol (CBD) oil, and butane hash oil (BHC) packaged in cartridges available in various flavors and concentrations are aerosolized by the heating of metal coils in the e-cigarette/vaping devices. Cases from all over the country have recently been coming to light in which vaping has led to severe acute pulmonary disease or vaping-associated-pulmonary-injury (VAPI). A vast majority of the presenting patients in the reported cases have required hospitalization and intensive care, needing supplemental oxygen and even endotracheal intubation and mechanical ventilation. 98% of patients present with respiratory symptoms (dyspnea, hypoxia, chest pain, cough, hemoptysis), 81% of patients have gastrointestinal symptoms (nausea, vomiting, diarrhea, and abdominal pain), and 100% of patients have constitutional symptoms such as fever, chills, and fatigue/malaise on presentation. Although based on history and clinical presentation it is reasonable to have a high suspicion for VAPI, diagnostic workup to rule out alternative underlying causes such as infection, malignancy, or autoimmune process should be performed before establishing the diagnosis. Computed Tomography (CT) scans of the chest have predominantly shown ground-glass opacity in the lungs, often with areas of lobular or subpleural sparing. Although lung biopsies have been performed on a relatively low number of cases, lung injury patterns so far have shown acute fibrinous pneumonitis, diffuse alveolar hemorrhage, or organizing pneumonia, usually bronchiolocentric, and accompanied by bronchiolitis. Treatment plans that have led to clinical improvement in the reported cases center around high-dose systemic steroids, although there are a lack of data regarding the best regimen and the absolute need for corticosteroids. The role of antibiotics appears to be limited once infection has definitively been ruled out. We present the case of a young male who vaped THC oil and developed severe acute pulmonary injury requiring mechanical ventilation and showed a remarkable response to high dose steroid therapy with improvement in clinical symptoms and resolution of diffuse ground glass opacity on repeat HRCT scan.
