“…One of the syndromes in calves with BRD is respiratory failure [9,10]. The term "respiratory failure" refers to the inability of external or internal respiration to provide blood with normal oxygen saturation and remove carbon dioxide, which is accompanied by weakness, cyanosis of the mucous membranes, and dyspnea [11][12][13]. Depending on the severity of dyspnea, there are three degrees of respiratory failure.…”

The goal of this study was to develop a method for the diagnosis of latent respiratory failure in calves with bovine respiratory disease (BRD) in farm conditions. The study involved 48 calves of the red-motley Holstein breed aged 14-28 days, with no previously experienced BRD, no dyspnea at rest, and a lack of anemia. Group I consisted of 24 calves with spontaneous or induced cough and WI clinical score of ≥5. Group II included 24 calves without spontaneous and induced cough and WI clinical score of ≤3. The determination of respiratory rate (RR), respiratory minute volume, and tidal volume in all calves was performed before and after functional exertion with a 15-min run and 30-s apnea. Blood samples were obtained from the jugular vein before 30-s apnea, then immediately after, and finally 1 min after apnea; blood gases and acid-base status were analyzed on an ABL-330, while total hemoglobin content was analyzed on a Micros-60. Tachypnea and dyspnea appeared after the 15-min run in group I calves, lasting 7.2 ± 0.4 and 3.7 ± 0.2 min. In group II calves, tachypnea lasted 3.8 ± 0.2 min, and no dyspnea occurred. Within 1 min, hypoxemia and hypercapnia caused by 30-s apnea in group II calves were compensated for due to an increase in pulmonary ventilation; in group I calves it was compensated for within more than 1 min, with presence of shallow breathing and dyspnea. The relation of RR immediately after 30-s apnea to RR before apnea showed excellent diagnostic value for detecting latent respiratory failure in the calves: area under the curve was 0.981, with cutoff point of ≥1.47, sensitivity of 95.8%, and specificity of 87.5%.

Objective This study was undertaken to describe the spectrum of lung computed‐tomography (CT) findings in children with pulmonary Langerhans cell histiocytosis (PLCH) and to evaluate for this population the CT‐scan nodule and cyst scores proposed by adult pulmonologists at diagnosis and during follow‐up. Methods Among 175 children with PLCH identified in the French national population‐based Langerhans cell histiocytosis cohort, 60 were retrospectively selected by the availability of CT for a central review by three pediatric radiologists. These 60 patients are representative of childhood PLCH for almost all clinical aspects, except a lower percentage of risk organ involvement (38% vs 54%; P = 0.05). Results The 60 children's chest CT scans (n = 218) were reviewed. At diagnosis, 63% of them had nodules, 53% had cysts, and 29% had both. The percentages of patients with nodules or cysts increased from diagnosis to peak disease activity, respectively, from 63% to 73% and from 53% to 66%. The costophrenic angle was involved in 71%. Patients with pneumothorax (25%) had a higher median cyst score. Alveolar consolidation was observed in 34%. Patients with low CT‐scan nodule and cyst scores had no long‐term pulmonary sequelae. Conclusions Well‐known characteristics of adult PLCH (nodules and cysts) were observed in children. The chest CT scores proposed by adult pulmonologists could easily be applied to childhood PLCH. Lesions in children, unlike those in adults, are frequently located near the costophrenic angles. Alveolar consolidation might be considered an atypical feature of childhood PLCH.

During the pandemic caused by the novel coronavirus (COVID-19), lung ultrasound has been used to diagnose and monitor respiratory condition. The aim of the study was to describe lung ultrasound findings in children with a COVID-19 infection. Patients younger than 18 years old and positive for COVID-19, admitted to pediatric tertiary referral hospital were included. They were divided into two groups depending on the presence of respiratory symptoms. Lung ultrasound results were categorized into three degrees of aeration loss: normal, moderate, and severe; and into three patterns: viral or bacterial pneumonia, and atelectasis.Sixteen patients were recruited. The median age was 11 years old (IQR 2.8-12). Four children (25%) required admission to the intensive care unit. Six patients (37.5%) presented with respiratory symptoms. All of them (100%) showed moderate-to-severe aeration loss on lung ultrasound. A viral pneumonia pattern was observed in four cases (66.6%). Ten patients (62.5%) presented with non-respiratory symptoms, lung ultrasound showed moderate-to-severe aeration loss in nine (90%). Three (30%) were diagnosed of multisystem inflammatory syndrome and lung ultrasounds showed severe aeration loss and bilateral pleural effusion.Conclusions: Children with COVID-19 and respiratory symptoms showed a viral pneumonia pattern with moderate-to-severe aeration loss upon the lung ultrasound assessment.
