Treatment focuses on airway protection, oxygen supplementation, stopping the bleeding, and addressing its cause.
Atelectasis is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid.
This document provides an overview of diseases of the pleura, including pleurisy, pleural effusion, empyema, pneumothorax, and mesothelioma. It discusses the anatomy and physiology of the pleura, causes and characteristics of pleural diseases, and how they are investigated and managed. Key points include that pleurisy is inflammation of the pleura causing chest pain, pleural effusion is abnormal fluid accumulation in the pleural space, and the fluid can be transudative or exudative depending on the underlying cause such as heart failure or infection/malignancy respectively.
Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. The fluid keeps your lungs from filling with enough air, which means less oxygen reaches your bloodstream. This deprives your organs of the oxygen they need to function.
Atelectasis is defined as an area of collapsed or non-expanded lung. There are four major types of atelectasis: (1) obstruction/resorption atelectasis caused by obstruction distal to the lung, such as from aspiration or COPD; (2) compression atelectasis caused by fluid, air, blood or tumor in the pleural space; (3) contraction (scar) atelectasis caused by fibrosis and scarring of the lung; and (4) patchy atelectasis caused by a lack of surfactant as seen in neonates and ARDS patients. Atelectasis causes decreased oxygenation and an increased risk of infection, though most cases are reversible disorders.
1. Acute respiratory failure results from inadequate gas exchange in the lungs, causing hypoxemia and hypercapnia.
2. It is not a disease itself but rather a condition caused by underlying lung diseases or disorders of other body systems that impair gas exchange.
3. Treatment goals include oxygen therapy to improve oxygenation, mobilizing secretions through coughing techniques, and positive pressure ventilation if needed to improve ventilation and gas exchange.
This document discusses atelectasis, which is the collapse or closure of alveoli in the lungs. It defines atelectasis and reviews its causes, types, symptoms, diagnosis, and treatment. Atelectasis can be obstructive or non-obstructive, acute or chronic. Risk factors include smoking and general anesthesia. Diagnosis involves chest x-ray, pulse oximetry, and arterial blood gas analysis. Treatment focuses on treating the underlying cause, chest physiotherapy, bronchodilators, surgery if needed, and preventing complications like pneumonia. Nursing care involves airway clearance techniques and strategies to improve ventilation and gas exchange.
Normally, the pleural space contains a small amount of fluid (5 to 15 mL), which acts as a lubricant that allows the pleural surfaces to move without friction.
But if fluid builds up from either increased production or inadequate removal pleural effusion results.
Pleural effusion B/L or unilateral (parapneumonic process)
Refers to any significant collection of fluid within pleural space.
Any imbalance in formation, absorption lead accumulation of pleural fluid. Common condition:

Atelectasis is defined as the collapse of pulmonary parenchyma resulting in loss of lung volume caused by inadequate expansion of airspaces. This leads to ventilation-perfusion imbalance and hypoxia. There are three main types of secondary or acquired atelectasis: resorption, compression, and contraction. Resorption atelectasis occurs due to obstruction preventing air from reaching distal airways, causing absorption of existing air and collapse. Compression atelectasis results from external pressures like pleural effusions. Contraction atelectasis involves fibrotic changes preventing full lung expansion. Atelectasis is potentially reversible through re-expansion of collapsed lung areas.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
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.

Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

3. Hemoptysis is defined as coughing of blood
originating from below the vocal cords.
The word "hemoptysis" comes from the Greek
"haima" meaning "blood“ & "ptysis" which means "a
spitting".
Hemoptysis can range from blood-streaking of
sputum to the presence of gross blood in the absence
of any accompanying sputum.
Definition
4. Life threatening (or) Massive hemoptysis is
defined as coughing of blood > 150 ml/episode (or) >
600 ml/24 hours.
Worldwide, the most common cause of hemoptysis is
tuberculous infection
The cause of hemoptysis cannot be determined in 20-30% of
cases.
Only 5% of hemoptysis is massive but mortality is 80%.
Definition
5. Pathophysiologic Factors:
1-Dual Circulation:
The lungs have a dual blood supply.
The pulmonary arterial circulation, a high-
compliance, low-pressure system that
terminates in the pulmonary capillary bed, is
responsible for gas exchange.
6. In addition, the lungs are supplied by the
bronchial arteries, branches of the aorta
that bring nutrients to the lung
parenchyma and major airways. The
bronchial arteries, like all systemic
arteries, are a high-pressure system. Most
cases of hemoptysis result from disruption
of branches of the bronchial arterial tree.
7. 2- Vascular Mechanisms:
• Aneurysm formation
• Vasculitis
• Pulmonary Embolism
• Inflammation
• Broncholithiasis
• Direct invasion of central pulmonary artery
• Trauma
11. Cardiovascular
Severe left ventricular heart failure
Mitral stenosis
Pulmonary embolism or infarction
Septic pulmonary embolism or right-sided
endocarditis
Aortic aneurysm or bronchovascular fistula

27. Advantages:
1) Tomography is valuable in selected cases to better show the presence
of lung cavities, solid masses, and mediastinal & hilar LDN.
2) Its complementary use with FOB gives a greater positive yield of
pathology & is useful for excluding malignancy in high-risk patients.
3) Allows application of special imaging techniques: e.g.,
HRCT (1-3mm thickness section) Bronchiectasis
Spiral CT with pulmonary angiography PE
Diagnosis
Computed Tomographic Scan (CT)
30. Value of Bronchoscopy
1-Diagnostic:
Localize site of bleeding
Foreign Body aspiration
Adenoma
2-Therapeutic:
Arrest bleeding
Suction and lavage
Preservation ventilation of bleeding lung
31. Advantages:
1. It is diagnostic for central endobronchial lesions.
2. Allows direct visualization of the bleeding site.
3. Permits tissue biopsy, bronchial lavage, or brushings for pathologic
diagnosis.
4. FOB also can provide direct therapy in cases of non massive
hemoptysis:
Instillation of diluted adrenaline.
Iced cooled saline.
Wedging & tamponade Fogarty catheter balloon
Diagnosis
Fiberoptic Bronchoscopy (FOB)
35. Angiography
Advantages:
1. Gold standard diagnostic tool for suspected PE.
2. Diagnosis of arteriovenous malformation.
3. Allows management of some cases of hemoptysis using
endovascular embolization.
Disadvantages:
1. Embolization of Spinal arteries paraplegia.
2. Needs special skills.
39. Management of Hemoptysis
Goal:
1. Evaluate the severity of hemoptysis.
2. Airway protection & patency.
3. Identify the site of bleeding.
4. Protect the contralateral un involved lung.
5. Stop the bleeding.
6. Treatment of the cause of bleeding.
40. Management Principles
• Airway control
– Supplemental Oxygen
– Positioning
– Cough control
– Endotracheal intubation or Selective
intubation
• Volume resuscitation
– Crystalloids
– Blood
41. Evaluation of Hemoptysis
1-Types of Hemoptysis:
Blood streaked
Frank Hemoptysis
Rusty sputum
2-Degree of Hemoptysis:
Massive
Non massive
42. Causes of Blood streaked Sputum:
Upper respiratory inflammation
Nose or Nasopharynx
Gums
Larynx
Severe coughing paroxysms
Trauma
43. Causes of Pink Sputum :
Blood and secretions mix in alveoli, small
bronchioles
Conditions associated with pink Sputum
– Pneumonia
– Pulmonary edema
46. Management of Massive
Hemoptysis
I. Medical:
Position of the patient sitting (or) bleeding side down
Large bore IV line fluids, blood transfusion
Supplemental Oxygen/ Mechanical ventilation.
Endotracheal tube (single wide bore (or) double lumen).
Cough suppressants
Pityressin (Vasopressin) 0.2-0.4 units/min. IV.
47. Management of Massive
Hemoptysis
II. Surgical:
Emergency resection for
bronchogenic mass.
Resection of bronchogenic
mass after patient
stabilization.
Surgical resection for
aspergilloma.
51. IV.Endovascular:
First results of embolization were published in 1973.
In most patients the bleeding originates from
bronchial arteries rather than pulmonary arteries.
Transcatheter embolization is effective in immediate
control of massive hemoptysis (73% - 98%).
Recurrence may be caused by:
Incomplete embolization of artery.
Recanalization of previously embolized artery.
Revascularization through collateral circulation.
Progression of basic lung disease.
Management of Massive
