Blog for Respiratory-Medicine-Post-Graduates of Apollo Hospitals,Chennai,India - Diplomate National Board(DNB), started in the Year 2009 October ,by PGs & the Academic Co-Ordinator of Department - Dr.R.P.Ilangho - for enabling these Young PGs to INTER_CONNECT ideally for becoming better Pulmonologists.The word~ REMAP09 ~ was coined thus:RE= RE spiratory M=M edicine A=Apollo P= P ostGraduate 09= 2009 - thus meaning "Respiratory Medicine Apollo PostGraduate 2009 batch"

CAUSES OF PLEURITIC CHEST PAIN
Pleuritic chest pain is a sharp, stabbing in the chest that worsens with respiratory movements such as deep breathing, coughing, sneezing, or laughing.
CAUSES:
1. Infectious Causes: These are among the most common reasons for pleuritic chest pain.
Viral Infections
Bacterial Infections: Pneumonia, Tuberculosis
Fungal Infections: Though less common, fungal infections can also inflame the pleura, especially in individuals with weakened immune systems.
Parasitic Infections
2. Inflammatory and Autoimmune Conditions:
Pleuritis due to inflammation caused by conditions such as SLE, Rheumatoid arthritis, Sarcoidosis
Pleural Effusion
3. Cardiovascular Causes:
Pulmonary Embolism
Pericarditis
4. Neoplastic Causes (Cancers):
Lung Cancer invading or irritating the pleura.
I Mesothelioma
Pleural Metastatic Cancers
5. Traumatic Causes:
Rib Fractures or Chest Injury
Thoracic surgery or other procedures involving the chest can lead to temporary pleuritic pain.
Differential diagnosis of ILD with family history:
Process: Adhesive laminating
Risk: Isocyanate prepolymers can cause an irritation of the airways and lungs leading to occupational asthma.
Process: Digital (ink-jet) printing
Risk: Carbon present in black ink can cause lung irritation. Methyl ethyl ketone and propanol can cause abnormal heart rhythm and rate and can affect the liver and kidneys on long term exposure.
Process: UV lamps for photo processing, UV curing and high speed printing – ink misting
Risk: Acrylates and methcrylates in fumes can cause irritation of respiratory tracts with the potential for occupational asthma as well as severe headaches and nausea.
Health Effects Of Chemicals Used In Printing
Process: Etching, Engraving, Platemaking, Photographic Reproduction
Risk: Nitric, sulphuric and hydrofluoric acids can cause skin burns, eye damage and blisters.
Process: Concentrated photographic developer or fixer solutions
Risk: Acidic salt solutions and Hydroquinone can irritate eyes and even cause dermatitis
Process: UV and infra red curable inks, varnishes and lacquers
Risk: Reactive acrylates or methacrylate’s can cause corrosion of the skin, eyes and mucous membranes.
Process: Lithographic platemaking, Gravure cylinder preparation and photoengraving.
Risk: Ammonium, potassium and sodium dichromate’s are all very corrosive and can cause deep ulcers as well as a risk of cancer.
Process: Lithographic fount solution, blanket restorers, cleaning solvents, Gravure and flexographic Risk: Alcohol, Esters and Ketones can cause dermatitis, dizziness and other effects of the central nervous system.
Process: Flexographic, Dyeline Printing and Screen Inks Risk: Perchloroethylene, Ammonium hydroxide and Ketones can cause dizziness, drowsiness and other effects on the central nervous system via inhalation.
Process: Screen Cleaning chemicals
Risk: Strong alkalis such as concentrated sodium or potassium hydroxide, Oxidisers and sodium hypochlorite solvents can cause corrosion of the skin, eyes and mucous membrane as well as dizziness and drowsiness
Diagnostic Criteria for PPF:
To diagnose PPF, all three of the following must be present:
Underlying fibrosing ILD (non-IPF), with imaging or histology showing fibrosis.
Evidence of progression within the past year, based on at least one of the following:
1.Worsening respiratory symptoms, such as increasing dyspnea or cough.
2.Decline in lung function, especially:
Absolute decline in FVC ≥ 5% predicted
Decline in DLCO (diffusing capacity for carbon monoxide) ≥ 10% predicted
3.Progressive fibrosis on imaging, shown by:
Increased reticulation
New ground-glass opacities with traction bronchiectasis
Increased honeycombing
No alternative explanation (e.g., infection, heart failure, pulmonary embolism).

The respiratory control system, broadly speaking, comprises a controller, sensors, and a plan. This hierarchical structure, in which there is central processing of afferent input, is important for coordinating respiratory movements with behaviors such as eating, speaking, and moving. The controller is a neuronal network within the central nervous system (CNS), which is responsible for generating and modulating individual breaths and the overall breathing pattern. Often referred to as the respiratory central pattern generator (rCPG), the controller comprises reciprocally connected neuronal populations in the medulla and pons. Neural output from the rCPG drives the activity of various motor neuron pools. Motor neurons in the spinal cord (e.g., phrenic and intercostal) innervate the respiratory pump muscles, while brain stem motorneurons innervate upper airway muscles. The so-called “plant” is animportant component of breathing control and includes the CO2stores, which are made up of lung stores and circulating blood volume including hemoglobin. Closed loop feedback to the controller is supplied by chemoreceptors and mechanoreceptors. The consistent cycling of the ventilatory pattern is generated spontaneously from the spatial and functional architecture of the rCPG. Intrinsic membrane properties of rhythmically active neurons within the rCPG are capable of producing automatic periodicity.4 In addition, reciprocal (excitatory and inhibitory) synaptic connections between neuronal populations in the medulla and pons are believed to be critical for the automatic generation of the respiratory rhythm.
