A 68-year-old Saudi man presented with chronic cough, shortness of breath, and wheezing for 5 years. Imaging showed right middle lobe bronchial thickening and distal collapse. Bronchoscopy found asthma-related changes. Laboratory results showed eosinophilia. He was diagnosed with right middle lobe syndrome due to severe asthma. Treatment involved aggressive asthma management, chest physiotherapy, antibiotics for exacerbations, and potential lobectomy for complications.
This document reviews tracheal bronchi and strategies for one-lung ventilation in patients with this anomaly. It begins with background on tracheal bronchi, including that they are a congenital anomaly occurring in 0.1-3% of people. It then discusses three classifications of tracheal bronchi and strategies for one-lung ventilation using double lumen tubes, bronchial blockers, or a single lumen tube. Key approaches involve using the classification to select the best device and techniques like sequential lung isolation.

It then discusses three classifications of tracheal bronchi and strategies for one-lung ventilation using double lumen tubes, bronchial blockers, or a single lumen tube. Key approaches involve using the classification to select the best device and techniques like sequential lung isolation.
The document discusses the triad of COPD which includes chronic bronchitis, emphysema, and chronic obstructive asthma. It describes the signs, symptoms, diagnosis, and imaging findings of COPD. On chest x-ray, COPD may show rapidly tapering vascular shadows and increased lung radiolucency. CT scanning can detect emphysema and determine if it is centriacinar, panacinar, or paraseptal. Management involves bronchodilators, rehabilitation, and glucocorticoids depending on the severity from mild to very severe COPD.
The document discusses the anatomy of the pericardium. It describes the pericardium as having an outer fibrous layer and inner serous layer with sinuses. It details the attachments, structures that pierce it, and its blood supply from the internal thoracic artery and coronary arteries. Complications like pericarditis and pericardial effusion are mentioned.
Chronic collapse of the right middle lobe, known as right middle lobe syndrome, is most commonly seen in elderly women. On chest x-rays, chronic collapse presents with subtle findings such as a triangular opacity pointing laterally where the normal horizontal fissure would be located and blurring of the right heart border. CT scans more clearly show the "tilted ice cream cone" appearance of the collapsed right middle lobe pressing against the heart. The document provides details on the radiographic presentation and characteristics of chronic right middle lobe collapse.
Respiratory Muscle Decline in Duchenne Muscular Dystrophy (2)Mahmoud Halawa
This study analyzed respiratory parameters in 28 boys with Duchenne muscular dystrophy (DMD) over 10 years to understand disease progression. Forced vital capacity (FVC) and sniff nasal inspiratory pressure (SNIP) were found to most accurately indicate respiratory muscle decline. Expiratory muscle strength assessed by maximum expiratory mouth pressure (Pgas cough) and diaphragm fatigue measured by transdiaphragmatic pressure-time product (TTdi) were also useful indicators. The study concludes that regular monitoring of FVC, SNIP, Pgas cough and TTdi from an early age is important for guiding treatment and understanding respiratory decline in DMD over time.
The document summarizes the key anatomical structures of the cardio respiratory system including:
- The inferior vena cava, superior vena cava, aorta, trachea, lungs, pleura, ribs, and intercostal structures.
- It describes the lobes and fissures of the right and left lungs. The right lung has 3 lobes divided by the oblique and horizontal fissures, while the left has 2 lobes divided by the oblique fissure.
- The pleura is described as a continuous layer consisting of parietal and visceral surfaces with a potential space that contains pleural fluid for lubrication.
Describes the basic radiology of diffuse interstitial disease ,with differential diagnosis of reticular interstitial pattern and how to approach HRCT findings .
1. The document describes the anatomical locations and classifications of mediastinal lymph nodes. It discusses 10 different lymph node stations located in the mediastinum, including the supraclavicular, upper and lower paratracheal, prevascular, subaortic, para-aortic, subcarinal, paraesophageal, pulmonary ligament, and hilar lymph nodes.
2. Conventional mediastinoscopy allows biopsy of stations 2L, 2R, 4L, 4R, and 7 while extended mediastinoscopy provides access to deeper stations 5 and 6. Endoscopic ultrasound with fine needle aspiration provides sampling of stations 7, 8, and 9.

Development of Diaphragm, Skull, Vertebrae & Limbs (Special Embryology)Dr. Sherif Fahmy
1) The diaphragm develops from the septum transversum, cervical myotomes, pleuro-peritoneal membrane, mesoesophagus, thoracic wall mesoderm, and mesoderm around the aorta.
2) The skull develops from two parts - the neurocranium which forms the brain box and viscerocranium. The neurocranium has a cartilaginous and membranous portion while the viscerocranium has membranous and cartilaginous portions.
3) The vertebral column develops from the notochord surrounded by sclerotomes which form the vertebral bodies. Vertebral bodies first form as me
- Emphysema can be caused by congenital factors, smoking, or alpha 1-antitrypsin deficiency. It results in destruction of lung tissue and inability to exhale fully.
- In emphysema, the air spaces in the lungs enlarge and the walls between them are destroyed. This reduces the surface area for gas exchange.
- Chest x-rays show enlarged, hyperinflated lungs in emphysema patients. Lobectomy is often used to treat congenital lobar emphysema in infants.
The document provides guidance on reading chest x-rays, including having a systematic approach, assessing film quality, and knowing anatomy. It recommends starting by checking patient details and film quality, then reviewing the airways, bones, cardiac silhouette, diaphragm, and lungs using a checklist. Specific features to examine in the lungs include over/under inflation, infiltrates, masses, and interstitial patterns.
The pericardium and the pericardial sinusesMohana Sekar
The pericardium is a double-walled sac that surrounds the heart and prevents overexpansion. It has an outer fibrous layer and inner serous layer. The pericardium supports the heart, limits its movement, and acts as a shock absorber. Pericardial effusion or inflammation can occur from infection, cancer, or other causes. Effusion is treated by draining fluid while inflammation is treated with anti-inflammatory drugs or identifying the underlying cause. Complications like tamponade require draining fluid from the pericardial sac.
1. The document describes the anatomy of the thorax, including boundaries, layers, and contents of the thoracic wall, mediastinum, and pleural spaces.
2. Key structures discussed include the lungs, heart, great vessels, trachea, esophagus, thymus, lymph nodes, and nerves of the thoracic cavity and mediastinum.
3. Clinical conditions involving the pleura and mediastinum are also summarized, such as pneumothorax, mediastinitis, and superior mediastinal syndrome.
1. Lung development begins in the fourth week of gestation and progresses through five stages - embryonic, pseudoglandular, canalicular, saccular, and alveolar.
2. Key molecular regulators of lung development include fibroblast growth factors, sonic hedgehog, retinoic acid, transforming growth factor beta, Wnts, platelet-derived growth factor and vascular endothelial growth factor.
3. Transcription factors such as NKX2-1, GLI genes, FOX family, GATA6 and SOX family also play important roles in lung development by regulating cell proliferation, branching morphogenesis and epithelial cell differentiation.
The respiratory system consists of an upper respiratory tract and lower respiratory tract. The upper tract includes the nose, pharynx and larynx, and conducts air. The lower tract includes the trachea, bronchi and lungs, and is where gas exchange occurs in the alveoli. Breathing involves inspiration and expiration through cyclic contraction and relaxation of the diaphragm and intercostal muscles. The lungs and pleural membranes allow for efficient gas exchange through a vast surface area in the alveoli.
Bronchial Artery Embolization- By Dr.Tinku JosephDr.Tinku Joseph
Bronchial artery embolization (BAE) is a minimally invasive procedure used to control massive or recurrent hemoptysis by occluding the blood supply to the lungs via selective catheterization and embolization of abnormal bronchial vessels. BAE has a high rate of immediate bleeding control of 57-100% and long-term control of 70-88%. Potential complications include tissue infarction if smaller embolic particles are used and transverse myelitis if branches supplying the spinal cord are inadvertently occluded. Careful angiography is required to identify the origin of vessels like the artery of Adamkiewicz to avoid neurologic complications during the procedure.
Combating Fraud and Intrusion Threats with Event ProcessingTim Bass
Combating Fraud and Intrusion Threats with Event Processing, TIBCO, TUCON 2007, Tim Bass, CISSP, Principal Global Architect, DirectorEmerging Technologies Group, TIBCO Software Inc.
This document discusses various congenital lung abnormalities including tracheobronchial abnormalities (such as tracheal agenesis, stenosis, and tracheo-esophageal fistula), pulmonary underdevelopment (such as lung agenesis and lobar hypoplasia seen in Scimitar syndrome), bronchopulmonary foregut malformations (including bronchogenic cysts, enteric cysts, and cystic adenomatoid malformation), diaphragmatic abnormalities (congenital diaphragmatic hernia and eventration), and pulmonary arteriovenous malformations. Imaging plays an important role in evaluating these conditions and establishing diagnoses.
The mediastinum is the central portion of the thoracic cavity located between the lungs. It is divided into the superior mediastinum above the sternal angle and inferior mediastinum below. The inferior mediastinum is further divided into the anterior, middle, and posterior mediastinum, with the middle mediastinum containing the heart and pericardium.
Styles of Scientific Reasoning, Scientific Practices and Argument in Science ...Elsa von Licy
The document discusses various topics related to scientific reasoning, practices, and argumentation including different styles of scientific thinking, features of scientific knowledge, and teaching and learning science. It provides examples of "crazy ideas" in science that are now accepted, examines the role of argument in science, and outlines the scientific practices and central questions of science. It also discusses developing models, planning investigations, analyzing data, and constructing explanations as key scientific practices.
Anti-philosophy rejects traditional philosophy and logic, instead embracing creativity, spirituality, and personality. It considers philosophy to be dead, kept alive artificially by analytic philosophers. The document criticizes how philosophy is currently taught and argues it has become unproductive, replacing original aims with nonsense. Anti-philosophy's goal is not to destroy philosophy but to transform its current state and avoid fundamentalism in philosophy and science.
There is no_such_thing_as_a_social_science_introElsa von Licy
This document provides an introduction and overview of the arguments made in the book "There is No Such Thing as Social Science". It begins by stating the provocative title and questioning whether the authors will take it back or qualify their position.
It then outlines three ways the term "social science" could be used - referring to a scientific spirit of inquiry, a shared scientific method, or reducibility to natural sciences. The authors argue against the latter two, methodological and substantive reductionism.
The introduction discusses how opponents may accuse the authors of being a priori or anti-reductionist, but argues that those defending social science are actually being dogmatic by insisting it must follow a scientific model. It frames the debate as being
