Tutorial contains images and text for pathology education. This is a lobar pneumonia in which consolidation of the entire left upper lobe has occurred. This pattern is much less common than the bronchopneumonia pattern. In part, this is due to the fact that most lobar pneumonias are due to Streptococcus pneumoniae (pneumococcus) and for decades. Lobar pneumonia is diffuse consolidation involving the entire lobe of the lung. Its evolvement can be broken down into 4 stages as follows: Congestion: This stage is characterized by grossly heavy and boggy appearing lung tissue, diffuse congestion, vascular engorgement, and the accumulation of alveolar fluid rich in infective organisms
Lobar pneumonia is an acute exudative inflammation of an entire pulmonary lobe, produced in 95 % of cases by Streptococcus pneumoniae (pneumococci). If not treated, lobar pneumonia evolves in four stages. Common to all stages is the enlargement of the affected lobe with loss of it's spongy appearance Lobar pneumonia Pathology outlines Lobar pneumonia - Wikipedi . Lobular pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung Bronchopneumonia (Lobular pneumonia) There are two main types of acute bacterial pneumonia : bronchopneumonia (with lobular topography) and lobar pneumonia (lobar topography). Bronchopneumonia (Lobular pneumonia) is an acute exudative suppurative inflammation of the lungs characterized by foci of consolidation surrounded by normal parenchyma Pontiac fever is caused by same bacteria, but without pneumonia, and often subclinical. Hilar lymph nodes infected in 50% of cases at autopsy; 25% have spread to other organs. Causes: contaminated water in water cooling tanks, drinking water conduits, air conditioning systems and other contained indoor water storage systems

A lobar pneumonia may result in expansion of the lobe due to voluminous edema, which is usually caused by infection with K. pneumoniae ( Fig. 3-2 ) Tutorial contains images and text for pathology education A closer view of the lobar pneumonia demonstrates the distinct difference between the upper lobe and the consolidated lower lobe. Radiographically, areas of consolidation appear as infiltrates

The Pathology of Specific Agents Pneumonia has been classified on the basis of the etiologic agent because the clinical and mor-phologic features, and the therapeutic implications often vary with the causative organism. Bacterial Pneumonia Streptococcus pneumoniae Streptococcus pneumonia accounts for 30% to 70% of the cases of community. Four stages of lobar pneumonia have been described. In the first stage, which occurs within 24 hours of infection, the lung is characterized microscopically by vascular congestion and alveolar edema This is an empyema. Pneumonia may be complicated by a pleuritis. Initially, there may just be an effusion into the pleural space. There may also be a fibrinous pleuritis. However, bacterial infections of lung can spread to the pleura to produce a purulent pleuritis. A collection of pus in the pleural space is known as empyema . At the left the alveoli are filled with a neutrophilic exudate that corresponds to the areas of consolidation seen grossly with the bronchopneumonia. This contrasts with the aerated lung on the right of this photomicrograph..
Lobar pneumnia is classically described in four stages: Congestion - day 1-2. Red hepatization - day 2-4. Gray hepatization - day 4-6. Resolution - day 6+. Note: The stages of lobar pneumonia is considered more-or-less historical. In the age of antibiotics, lobar pneumonia is uncommon Tutorial contains images and text for pathology education At higher magnification can be seen a patchy area of alveoli that are filled with inflammatory cells. The alveolar structure is still maintained, which is why a pneumonia often resolves with minimal residual destruction or damage to the lung

TREATMENT:-. - Confine the patient in bed, and frequently change is position. - Keep the room at an even temperature and the atmosphere moistened with steam. - The diet should be nutritious and liquid is more. - Treatment may be started with co-trimoxazole or ampicillin orally or gentamicin intra-muscularly Congenital cystic adenomatoid malformation (CCAM) of the lung is an uncommon fetal development anomaly of the terminal respiratory structures. The large cyst type usually occurs in stillborn infants or newborn infants with respiratory distress. Cases of CCAM have been previously described in adulthood, more often type I with multiloculated cystic lesions
Congenital Lesions of the Lung Marleta Reynolds Most congenital lesions of the lung are recognized when respiratory symptoms develop in the newborn or infant. An increasing number are being diagnosed prenatally. Some are identified in the asymptomatic child on an incidental radiograph of the chest. The remainder are diagnosed in the older child during evaluatio bronchopneumonia and lobar pneumonia in being relatively free of polymorphonuclear leucocytic exudate. 7. Such areas failed to reveal microorganisms on tissue section. 8. With the advent of secondary bacterial invasion the gross and microscopic pictures were altered: in somepatients there were areas ofacute interstitial pneumonia adjacent to. Bronchopneumonia is a type of pneumonia, a condition that causes inflammation of the lungs. Symptoms can range from mild to severe and may include coughing, breathing difficulties, and fever

Imaging and clinical manifestations of viral pneumonia are not reliably predictive of its origin. Herein, emphasis was placed on the commonest imaging features of some of the most common viruses that produce pulmonary disease. Thin-section CT is an effective diagnostic method when findings at chest radiography are normal or inconclusive When you hear the words lung defect, your heart sinks and your world may crumble, at least for a little while. At some point, after you received that specific diagnosis of Congenital Lobar Emphysema, you probably started to search for as much information as you could possibly get your hands on
Eosinophilic lung diseases are a diverse group of pulmonary disorders associated with peripheral or tissue eosinophilia. They are classified as eosinophilic lung diseases of unknown cause (simple pulmonary eosinophilia [SPE], acute eosinophilic pneumonia [AEP], chronic eosinophilic pneumonia [CEP], idiopathic hypereosinophilic syndrome [IHS]), eosinophilic lung diseases of known cause. As opposed to the lobar pneumonia, bronchopneumonia is less likely to be found in association with the streptococcus. On the other hand, it is often found in association with the hospital-acquired pneumonia and the specific bacterial organisms that are behind it - meaning the staphylococcus aureus, E.coli, Klebsiella or pseudomonas . We assessed the clinical phenotype, frequency, clinical implications (surgery, length of treatment in hospitals/intensive care units, and antibiotic treatments), and potential preventability of severe PVL-SA infections in children. Total, 75 children treated for PVL-SA infections in our in- and outpatient units from 2012 to 2017 were included in this retrospective study. Ten out of 75. Nonspecific Interstitial Pneumonia (NSIP) Nonspecific interstitial pneumonia (NSIP) is a rare lung disorder that can cause difficulty breathing, a dry cough, fatigue and other symptoms.

After decades of research, large-scale clinical trials in patients diagnosed with frontotemporal lobar degeneration (FTLD) are now underway across multiple centres worldwide. As such, refining the determinants of survival in FTLD represents a timely and important challenge. Specifically, disease outcome measures need greater clarity of definition to enable accurate tracking of therapeutic. There are five major histologic patterns of tissue reaction in infections. 1. Suppurative (Polymorphonuclear) Inflammation. This pattern is the reaction to acute tissue damage, characterized by increased vascular permeability and leukocytic infiltration, predominantly of neutrophils. The neutrophils are attracted to the site of infection by.
The ordinary clinical lobar pneumonia, due to the pneumococus, prevailed until about March 20; then, abruptly the streptococcus type predominated, with a very great increase in the incidence of the disease. From September 20 until March 20, which marks the period of ordinary lobar pneumonia, 276 cases were treated This narrative review outlines the pathophysiology and electrocardiographic findings associated with COVID-19. Discussion COVID-19 is a potentially critical illness associated with a variety of ECG abnormalities, with up to 90% of critically ill patients demonstrating at least one abnormality Organising pneumonia is defined pathologically by the presence in the distal air spaces of buds of granulation tissue progressing from fibrin exudates to loose collagen containing fibroblasts (fig1).1 ,2 The lesions occur predominantly within the alveolar spaces but are often associated with buds of granulation tissue occupying the bronchiolar lumen (bronchiolitis obliterans)
