ICU imaging
This document discusses various conditions that can be identified on ICU imaging. It lists numerous pulmonary complications that can be seen on chest imaging for patients in the ICU, such as ARDS, pulmonary edema, pneumonia, and pulmonary embolism. It also lists various brain conditions that might appear on neuroimaging, such as hemorrhage, infarcts, and hydrocephalus. Finally, it discusses findings that can be identified on lung ultrasound, including pneumothorax, pleural effusions, and lung consolidations.
CXR: Multiple Cavities
The chest x-ray shows multiple cavitary lesions bilaterally with areas of consolidation and fibrosis in both lungs. A CT scan found fibrotic changes in both upper lobes with bronchiectatic changes in the left lower lobe. There are multiple thin-walled cavities seen ranging in size from 10x2x4.2 cm in the left lung to 11x3x5.4 cm in the right lung. Patchy consolidation is seen in the left lower lobe along with fibrosis and traction bronchiectasis in the left upper lobe.
CXR - Cavity in Lung
The chest x-ray shows a wedge-shaped opacity in the right middle lobe of the lung with a thick-walled irregular cavity and associated collapse. This could indicate sequelae from a previous infection, malignancy, or other conditions. Cavities in the lung can be caused by infections like tuberculosis, fungi, and parasites; immune-mediated diseases like Wegener's granulomatosis and sarcoidosis; neoplasms; blood clots; or airway diseases such as bullae and cystic bronchiectasis. Further evaluation is needed to determine the underlying etiology.
11 cavitary lesions of the lungs
This document discusses various types of cavitary lung lesions seen on imaging. It includes 18 figures showing examples of cavitary lesions caused by conditions such as bacterial abscesses, tuberculosis, fungal infections, metastases, pulmonary emboli, bronchiectasis, emphysema, cystic fibrosis, and papillomatosis. The cavities vary in appearance depending on the etiology, with differences in size, wall thickness, presence of air-fluid levels, and associated findings. Proper diagnosis relies on correlating the clinical history and imaging appearance.

Enfermedad pulmonar obstructiva crónica
This document discusses different types of chronic obstructive pulmonary disease (COPD) including emphysema and chronic bronchitis. It describes the pathology of emphysema, including different types like centriacinar, panacinar, and paraseptal emphysema. Chronic bronchitis is defined as a persistent cough with sputum production for at least three months out of the year for two or more years. The document also discusses asthma as a chronic inflammatory airway disease characterized by wheezing, shortness of breath, and airway obstruction that is at least partially reversible.
Cavitatory lesions of the lung
This document discusses cavitary lung lesions seen on imaging and their characteristics. It defines bullae, cysts and cavities. Cavities are air-filled spaces surrounded by a thick wall (>3mm) and are often due to necrosis. Characteristics like wall thickness, inner contour, internal content, number and location can help determine if a cavitary lesion is benign or malignant. Thick-walled cavities often indicate infection or cancer while thin-walled cavities suggest granulomatous diseases or metastases. Common causes of cavitary lesions discussed are infections, neoplasms, vascular diseases, and autoimmune disorders.
Casos clinico-Radiológicos
The document describes a case of a man with difficulty breathing. Imaging found a large mass displacing the heart and mediastinum to the right in the left lung, with an air-fluid level. The mass angles acutely with the pleural surface. The differential diagnosis included lung abscess, empyema, pneumatoceles, and infected bullae. CT findings supported the diagnosis of a large lung abscess, which is a complication of untreated bacterial infections and occurs in areas of underlying infection. Lung abscesses are treated with antibiotics and follow up imaging to monitor resolution, which occurs through bronchiectasis, cystic change, and scarring. Untreated lung abscesses have a 30% mortality rate.
Radiological signs of chest diseases
This document discusses various radiological signs seen on chest imaging. It describes signs such as the "S curve of golden" seen with masses adjacent to fissures, the "pulmonary artery overlay sign" seen when the interlobar pulmonary artery is visible behind or in front of a mass. Other signs discussed include those seen with conditions such as achalasia of the esophagus, pneumomediastinum, and extrapulmonary masses. The document also summarizes CT findings associated with various pulmonary diseases and abnormalities.
CT Chest: Pleural Thickening
This x-ray shows opacity in the right lower lung zone and pleural thickening on the right side. A CT scan confirms pleural effusion on the right lung with thickening and fibrotic changes in the right middle and lower lobes. Pleural thickening represents the end stage of various inflammatory processes like infection or asbestos exposure, and can cause ventilatory impairment. It appears as a band of soft tissue density parallel to the chest wall, and is seen as homogenous echogenic layer on ultrasound if over 1cm thick.
Chest slides to share
This document contains chest imaging findings from cases in Zambia, including various pulmonary infections, masses, and other pathologies. Pulmonary tuberculosis is shown in HIV-positive patients, along with opportunistic infections like Pneumocystis jirovecii pneumonia. Other findings illustrated include aspergillosis, radiation pneumonitis, empyema, lung cancers, sarcomas, and mediastinal abnormalities such as lymphadenopathy, cysts, and aneurysms. The importance of chest x-ray and CT for evaluating unusual signs is emphasized.
Diseaes of the pleura
The pleura are two-layered membranous sacs that fold back on themselves. The pleural cavity is the thin fluid-filled space between the two pleural layers surrounding each lung. It contains pleural fluid and allows for lung expansion. Pleural effusions are accumulations of fluid in the pleural space that can be exudative due to infections or malignancy, or transudative due to conditions like heart failure. Pneumothorax is the presence of air in the pleural space, and tension pneumothorax occurs when air enters but cannot exit the pleural space on exhalation.

Cerebral Fat Embolism in ICU
This document describes a case of cerebral fat embolism syndrome (FES) in a 25-year-old man admitted to the ICU. He fell into the sea from a ship and was submerged for 45 minutes, sustaining multiple long bone fractures. He later developed respiratory failure, seizures, and decreased consciousness consistent with FES. Imaging and labs supported the diagnosis. He was treated supportively in the ICU with ventilation, antibiotics, and steroids. His condition gradually improved and he was discharged from the ICU after three weeks of care. The document also provides background information on FES, including causes, pathophysiology, diagnostic criteria, management, and prognosis.
MICROCIRCULATION IN ICU
This document discusses microcirculation monitoring in critical illness. It begins with an introduction to microcirculation and its role in tissue oxygenation. It then discusses four types of microcirculatory alterations that can result in a loss of coherence between the macrocirculation and microcirculation: heterogeneity, hemodilution, constriction/tamponade, and edema. Specific microcirculatory alterations seen in sepsis and surgery are also reviewed. Monitoring microcirculation is important for guiding resuscitation efforts and assessing whether macrocirculation improvements translate to the microcirculation level.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
