Abstract Introduction/Objective Acute interstitial pneumonia (AIP) is a rare disease clinically characterized by rapidly progressing respiratory failure in individuals with no history of respiratory illness or other inciting factors. While most often diagnosed in middle-aged adults, it may present in any age group. Initial presentation is described as influenza- like, and respiratory failure requiring ventilatory support often progresses within weeks to months. Prognosis is poor, with an estimated mortality rate approaching 80% without treatment. Methods We present the case of a 44-year-old male nonsmoker with no significant medical history, who presented in 2018 with 1.5 months of dyspnea and headache initially diagnosed as atypical pneumonia. Chest imaging revealed bilateral opacities; however, microbial workup revealed no evidence of infectious etiology. Autoimmune serology studies were likewise unrevealing. Despite aggressive supportive and medical management, he deteriorated to respiratory failure and succumbed. Results At autopsy, the lungs were symmetrically congested and edematous (combined weight 2,340 g) but free of evident consolidation or discrete lesions. Microscopic examination revealed diffuse alveolar damage with extensive hyaline membrane formation, interstitial edema, and fibroblastic proliferation. The vasculature was severely congested, and the alveoli contained hemorrhage and scattered macrophages. No fungal or mycobacterial elements were identified by staining. Based on the histologic features and clinical context, the diagnosis of AIP was made. Conclusion AIP is a rare, aggressive, and diagnostically challenging disease that includes a broad range of both clinical and histologic differentials. Timely recognition and intervention with aggressive respiratory support and high- dose glucocorticoids are the mainstays of clinical management. The diagnostic role of histology is significant, but hinges on early clinical consideration of AIP as disease progression may later preclude the biopsy procedure. We share this case to raise awareness of this rapidly progressive and diagnostically troubling interstitial lung disease while emphasizing the importance of clinicopathologic correlation.

The present case report describes a 44-year-old woman who presented with dyspnea due to diffuse interstitial lung disease. High-resolution computed tomography showed features of usual interstitial pneumonia, but the lung biopsy obtained by video-assisted thoracoscopy was consistent with a histological pattern of nonspecific interstitial pneumonia. Following the procedure, the patient developed progressive respiratory distress and died on postoperative day 13 with a clinical picture of acute interstitial pneumonia. The autopsy showed evidence of diffuse alveolar damage superimposed on the background pattern of nonspecific interstitial pneumonia. The present case report supports the notion that patients with a variety of subtypes of idiopathic interstitial pneumonias may be at risk of exacerbation of their underlying disease following thoracic procedures, including video-assisted thoracoscopic lung biopsy.

Introduction: Myasthenia gravis (MG) is an acquired autoimmune disorder clinically characterized by skeletal muscle weakness & fatigability on exertion with prevalence as high as 2–7 in 10,000 and women are affected more frequently than men (~3:2). Over 12-16% of generalized MG patients experience crisis once in their lifetime. A serious complication of myasthenia gravis is respiratory failure. This may be secondary to an exacerbation of myasthenia (myasthenia crisis) or to treatment with excess doses of a cholinesterase inhibitor (cholinergic crisis). Case Report: Thirty-two years old woman refereed from a private hospital to ED for further treatment with myasthenia in crisis, after nine days of treatment in the previous ICU. Patient already in intubation with mechanical ventilation and history of the treatment of a high dose of multiple anticholinesterase drugs and steroids without plasmapheresis or immunoglobulin intravenous. During admission, diarrhea was present, with no sign of GI infection. On the third day of admission, the patient performed a Spontaneous Breathing Trial and was a success then extubated. Then two day after extubation, the patient falls to respiratory failure and need mechanical ventilation. Anticholinesterase test was performed, and it shows no improvement in clinical signs, and diagnose as Cholinergic Crisis. After re-adjustment of anticholinesterase drug with a lower dose, clinically, the respiratory condition improved, and on the 10th day of admission, the patient was succeed extubated. At 12nd days of ICU admission, patient discharge from ICU. Discussion: Myasthenia and Cholinergic Crisis is a severe and life-threatening condition characterized by generalized muscle weakness with a respiratory compromise that requires ventilatory support. Respiratory failure may be present in the cholinergic crisis without cholinergic symptoms (miosis, diarrhea, urinary incontinence, bradycardia, emesis, lacrimation, or salivation). The most important management aspect of Myasthenia patients in crisis is the recognition and treatment of myasthenia vs cholinergic crisis.

Abstract Background Interstitial lung disease (ILD) patients requiring invasive mechanical ventilation (IMV) for acute respiratory failure (ARF) are known to have a poor prognosis. Few studies have investigated determinants of outcomes and the utility of trialing non-invasive positive pressure ventilation (NIPPV) prior to IMV to see if there are any effect(s) on mortality or morbidity. Methods We designed a retrospective study using patients at four different intensive care units within one health care system. Our primary objective was to determine if there are differences in outcomes for in-hospital and one-year mortality between patients who undergo NIPPV prior to IMV and those who receive only IMV. A secondary objective was to identify potential determinants of outcomes. Results Of 54 ILD patients with ARF treated with IMV, 20 (37.0%) survived to hospital discharge and 10 (18.5%) were alive at one-year. There was no significant mortality difference between patients trialed on NIPPV prior to IMV and those receiving only IMV. Several key determinants of outcomes were identified with higher mortality, including: higher ventilatory support, idiopathic pulmonary fibrosis (IPF) subtype, high dose steroids, use of vasopressors, supraventricular tachycardias (SVTs), and higher body mass index. Conclusions Considering that patients trialed on NIPPV prior to IMV was associated with no mortality disadvantage to patients treated with only IMV, trialing patients on NIPPV may identify responders and avoid complications associated with IMV. Increased ventilator support, need of vasopressors, SVTs, and high dose steroids reflect higher mortality and palliative care involvement should be considered as early as possible if lung transplant is not an option.

As of now, about 380 medications are implicated in causing respiratory reactions and most common among that is drug-induced interstitial disease.Oral, parental as well inhalational drugs are known to cause drug-induced interstitial lung disease. Bleomycin is a chemotherapeutic agent used inthe treatment of lymphomas, germ cell tumors of the testes. Most common pulmonary toxicity is diffuse alveolar damage with nonspecific interstitialpneumonitis being next. We report a case of bleomycin-induced reversible acute interstitial pneumonia in a Hodgkin’s lymphoma patient with adriamycin, bleomycin, vinblastine, dacarbazine regimen. Causality assessment was done using Naranjo scale, and probable causal relationship was established. Adverse drug reaction was found to be moderately severe and not preventable as per Hartwig’s severity and Thornton’s preventability scaling respectively.Keywords: Naranjo scale, Lymphoma, Bleomycin, Pneumonia.

This paper presents autopsy findings of 3 COVID-19 patients randomly selected for post-mortem from two tertiary referral Polish hospitals. Analysis of macroscopic, histopathological findings with clinical features was performed. All 3 deceased patients were Caucasian males (average age 61 years, range from 56 to 68 years). Using real-time polymerase chain reaction assay, the patients were confirmed (antemortem) to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Two patients were obese, and 1 patient had type 2 diabetes mellitus. The medical history of 1 patient included hemorrhagic pancreatitis, gangrenous cholecystitis, <i>Acinetobacter baumanii</i> sepsis, and cholecystectomy. Pulmonary embolism was diagnosed in 2 patients. At autopsy, in 1 case, the lungs showed bilateral interstitial pneumonia with diffuse alveolar damage (DAD), while in another case, interstitial pulmonary lymphoid infiltrates and enlarged atypical pneumocytes were present but without DAD. Microthrombi in lung vessels and capillaries were observed in 2 cases. This study revealed thrombotic complications of COVID-19 and interstitial pneumonia with DAD presence as the main autopsy findings in patients with SARS-CoV-2 infection that was confirmed antemortem with molecular tests. Autopsy studies using tissue sections handled in accordance with <i>SARS</i>-CoV-2 biosafety guidelines are urgently needed, especially in the case of subjects who were below the age of 60.

Since its original description in 1956 the association between interstitial lung disease and polymyositis (PM) and dermatomyositis (DM) has become well established. Interstitial lung disease (ILD) can be a significant complication in rheumatic diseases (RDs). Although most patients with RD do not develop clinically evident ILD, these systemic autoimmune disorders are estimated to be responsible for approximately 25% of all ILD deaths and 2% of deaths due to all respiratory causes. Radiologic abnormalities in DM are characterized by a high incidence of airspace consolidation. Non-Specific Interstitial Pneumonia (NSIP) is the most common form of lung disease, with a frequency in biopsies 4-fold greater than that of Usual Interstitial Pneumonia (UIP) in PM and a slightly smaller predominance in DM. We report a case of a female patient, 57 years old, no former smoker, whose clinical history was onset in November 2008 with asthenia with muscle and osteoarticular pain especially located in the upper limbs and then also expanded to the lower limbs. The EMG was compatible with dermatomyositis in the acute phase. The patient received therapy with steroids and tacrolimus, also making several rounds of treatment with immunoglobulin. Given the recurrence of myositis in association with signs of poorly controlled interstitial lung disease, immunosuppressive therapy with Rituximab was administered. The Computed Tomography (CT) scans showed "bronchiectasis and traction bronchiolectasis, hypodense areas consistent with the phenomena of air trapping. The pattern of interstitial lung disease with fibrotic evolution seems consistent with NSIP. The arterial blood gas analysis showed a pattern of hypoxic-hypercapnic respiratory failure (pH: 7,34, PaO2: 67 mmHg; PaCO2: 55 mmHg). As a result of an episode of marked desaturation unresponsive to supplemental oxygen at high flows we proceeded to noninvasive mechanical ventilation with Helmet for 24 hours/24. This ventilatory support was maintained for a week, with resolution of the respiratory failure. In this brief case report we want to highlight various pulmonary complications as a result of dermatomyositis. The progression of respiratory complications may also lead to a situation of respiratory failure, as in our patient, and require a noninvasive ventilatory treatment.

Background: Two notable findings of clinically healthy feedlot cattle suggest they may have pulmonary hydrostatic edema during the finishing phase of production: increased pulmonary arterial wedge pressures and pulmonary venous hypertrophy. The goal of this study was to determine if increased pulmonary arterial wedge pressure (PAWP) in a Holstein calf could lead to diffuse alveolar damage consistent with the early, exudative phase of acute interstitial pneumonia of feedlot cattle. Methods: Six male Holstein dairy calves were given daily subcutaneous injections of the nonspecific ß-adrenergic agonist isoprenaline (10 mg/kg/d), to induce left ventricular diastolic dysfunction, or sterile water for 14 days. On Day 14, pulmonary arterial pressures and wedge pressures were measured, echocardiography performed, and the ratio of mitral valve flow velocity (E) to septal lengthening velocity (e’) calculated. Calves were euthanized on Day 15 and lung lesions semi-quantitatively scored. Results: Mean PAWP was 12 ± 1 mm Hg in calves that received isoprenaline and 7 ± 1 mm Hg in controls (P = 0.01). Calves that received isoprenaline tended to have greater relative wall thickness than control calves (P = 0.15) and greater E/e’ ratios (P = 0.16), suggestive of concentric hypertrophy and diastolic dysfunction, respectively. Calves that received isoprenaline also tended to have a left ventricle and interventricular septum that was 29 ± 10 g heavier than control calves (P = 0.10) when controlling for body mass. Hyaline membranes, the hallmark feature of diffuse alveolar damage, were evident in lung sections from all calves that received isoprenaline but none of the controls. Conclusions: Consistent with prior pathological and physiological studies of feedlot cattle, this study provides preliminary evidence that cattle presenting with clinical signs and pathology consistent with early stage acute interstitial pneumonia could be attributable to hydrostatic edema associated with left ventricular failure.
