This document provides an overview of tuberculosis (TB), including its definition, causes, pathogenesis, clinical presentation, investigations, types, treatment regimens, and relationship to HIV/AIDS. TB is caused by mycobacteria, commonly Mycobacterium tuberculosis, which can affect any organ but typically affects the lungs. It is transmitted via airborne droplets from someone with active pulmonary TB. Primary infection may result in latent TB or active TB, depending on immune response. Symptoms vary based on location of infection. Diagnosis involves chest x-ray, sputum smear, and Mantoux test. Treatment involves a combination of bactericidal and bacteriostatic drugs. Multi-drug resistant TB can develop if treatment is not completed
Tuberculosis is a chronic infectious disease caused by the bacterium Mycobacterium tuberculosis. It typically affects the lungs but can also affect other parts of the body. It spreads through the air when people who are sick with TB disease of the lungs or throat cough, sneeze, speak, or sing. Diagnosis involves a combination of physical examination, chest X-ray, tuberculin skin test, blood tests, and microbiological examinations of body fluids and tissues. Treatment requires multiple antibiotics taken for a minimum of 6 months. Proper treatment is important to cure the individual and prevent further transmission.
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and can affect the lungs (pulmonary TB) or other organs (extrapulmonary TB). It spreads through the air when people with active TB cough, sneeze or speak. While most exposed people develop latent TB infection, 10% will develop active disease. Diagnosis involves chest x-rays, sputum smear and culture tests, and treatment requires a multi-drug regimen to prevent drug resistance. HIV co-infection increases the risks of developing active TB and facing treatment challenges.
Tuberculosis is an infectious disease. In this presentation shortly information has been extracted from text books of Medicine and Bangladesh National Guidelines of Tuberculosis (4th & 5th edition). here drugs, FDC and effects have been reviewed also.
This document discusses various fungal infections of the chest and their imaging appearances. It provides an overview of 9 main fungal organisms (Histoplasmosis, Coccidioidomycosis, Blastomycosis, Paracoccidioidomycosis, Candidiasis, Pneumocystis, Cryptococcosis, Mucormycosis, Aspergillosis) and summarizes their typical radiographic or CT findings. These include calcified nodules, cavitating lesions, consolidations, ground glass opacities, and halo signs which help differentiate the fungal pathogens.
This document provides an overview of tuberculosis (TB), including its definition, causative agents, types, risk factors, pathophysiology, clinical presentation, differential diagnosis, investigation, and treatment. TB is an infectious disease caused mainly by the bacterium Mycobacterium tuberculosis that typically affects the lungs. It can be transmitted through airborne droplets when an infected person coughs or sneezes. There are two main types - pulmonary TB affecting the lungs and extra-pulmonary TB affecting other organs. Risk factors include contact with infected individuals, immunosuppression, and lifestyle factors like drug/alcohol misuse. Treatment involves a two-phase drug regimen over 6-10 months with first-line antibiotics like rifampin,
Moderator: Prof. (Dr) A.K. Sen presented on tuberculosis with the following presenters: Kolli Ajit Kumar, Krishna Nath, Lavita Hazarika, Lipika Devi, and Luish Bor Boruah. Tuberculosis is a chronic bacterial infection caused by Mycobacterium tuberculosis that is characterized by granuloma formation in infected tissues. It most commonly affects the lungs and is transmitted via aerosolized droplets. Diagnosis involves microscopy, culture, and molecular testing of respiratory or other clinical specimens to detect the tuberculosis bacteria.
The document discusses the history, causes, transmission, diagnosis and treatment of tuberculosis (TB). It describes how TB is caused by the Mycobacterium tuberculosis bacteria and is usually transmitted through airborne droplets when infected people cough, sneeze or speak. The diagnosis and treatment of latent TB versus active TB disease is also explained, noting that active TB causes symptoms and can be infectious while latent TB does not cause symptoms but the bacteria are still present.

This document discusses miliary tuberculosis. It begins with an introduction that defines miliary TB and outlines its history, risk factors, types, pathophysiology, clinical findings, diagnosis, treatment, and prevention. Miliary TB is a disseminated form of extra pulmonary TB caused by hematogenous spread of mycobacteria through the bloodstream. It most commonly appears as small, millet seed-sized lesions scattered throughout multiple organs. Symptoms can include weakness, fever, weight loss, and hepatomegaly. Diagnosis involves blood tests, lumbar puncture, cultures, and chest imaging. Treatment typically involves a multi-drug regimen over 6-9 months.
1. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and affects mostly the lungs. It is both preventable and curable.
2. The most common age group affected is 15-45 years old. Factors that increase the burden of TB include HIV, poor socioeconomic status, poor nutrition, and limited access to healthcare.
3. TB treatment aims to cure patients, prevent transmission and death, and prevent drug resistance. Treatment follows principles of using multiple drug combinations under direct observation to ensure adherence and prevent resistance.
This document provides information on the history, epidemiology, microbiology, pathogenesis, diagnosis and clinical features of tuberculosis. Some key points:
- Tuberculosis is an ancient disease that has affected humans for thousands of years. Robert Koch discovered the causative bacteria, Mycobacterium tuberculosis, in 1882.
- In 2020, there were an estimated 10 million new TB cases and 1.5 million TB deaths worldwide, making it one of the top 10 causes of death. India has the highest burden of cases.
- M. tuberculosis is an aerobic bacterium with a complex cell wall structure that allows it to be acid-fast staining. It typically causes a chronic pulmonary infection but can spread to other
Pulmonary tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It is transmitted via airborne droplets when people with active TB cough, sneeze or spit. Primary tuberculosis occurs when someone is initially infected, usually resulting in a self-limited infection. Post-primary tuberculosis occurs after a latent period and is usually due to reinfection or reactivation of a latent infection. Diagnosis involves microbiological testing of sputum samples, chest imaging, and tuberculin skin testing or interferon-gamma release assays. Radiographic findings can help determine if a case is active or inactive.
This document discusses pulmonary manifestations in HIV patients. It begins with an introduction to HIV transmission and risk groups. It then discusses how HIV affects the lungs, causing direct infection and immune dysfunction. Common pulmonary conditions in HIV patients are described, including opportunistic infections like Pneumocystis pneumonia and tuberculosis, which present differently based on CD4 count. Imaging findings for various lung diseases seen in HIV are provided, with examples of abnormalities seen on chest x-ray and CT for conditions like Pneumocystis pneumonia and bacterial/mycobacterial infections. Risk factors, diagnosis and treatment approaches are also summarized.
Tuberculosis is a chronic, wasting, communicable disease, which made a huge comeback with the HIV pandemic, making it an opportunistic infection, and and an AID-defining infection. This presentation explores the different types of tuberculosis in terms of their locations (pulmonary and extra-pulmonary) as well as in terms of their drug susceptibility. It also addresses the approach to the management of each one of these.
This document discusses the various radiological manifestations of tuberculosis (TB) in the chest and other body systems. It covers pulmonary TB including primary and post-primary TB pneumonia, cavitary TB, tuberculomas, and miliary TB. It also discusses mediastinal TB, airway TB such as endobronchial TB and bronchiectasis. Extrapulmonary manifestations including pleural TB, lymphadenopathy, skeletal TB, and special forms are described. For each topic, the pathogenesis, location, and characteristic radiological findings are summarized. Differential diagnoses are also provided for some conditions.
Tuberculosis is an infectious disease that mainly affects the lungs and is caused by the Mycobacterium tuberculosis bacteria. It spreads through tiny droplets released into the air via coughs and sneezes. Common symptoms include coughing for more than three weeks, coughing up blood or mucus, chest pain, unintentional weight loss, fever, and night sweats. Diagnosis involves skin tests, blood tests, chest x-rays, and sputum samples. Treatment requires taking combinations of antibiotics for several months. Complications can include spinal pain, joint damage, meningitis, and liver or kidney problems.
1. Managing lymph node tuberculosis can be challenging as it has varied clinical manifestations and diagnostic challenges.
2. It most commonly involves cervical lymph nodes but can affect nodes throughout the body.
3. Diagnosis may involve imaging like ultrasound, CT, or MRI to identify enlarged or cystic lymph nodes, as well as biopsy to confirm the presence of Mycobacterium tuberculosis.
4. Treatment often requires a multi-drug antibiotic regimen over a prolonged period.
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It infects the lungs and can spread to other parts of the body. Symptoms include cough, fever, weight loss, and night sweats. It is diagnosed through skin tests, chest x-rays, and sputum analysis. Treatment involves a combination of antibiotics over several months. With proper treatment, TB patients can fully recover but the disease remains a major global health problem.
Opportunistic infections are infections that occur more frequently and are more severe in people with weakened immune systems such as those with HIV/AIDS. These infections include fungal, bacterial, viral, and parasitic infections that typically do not seriously affect those with healthy immune systems. Common opportunistic infections in HIV/AIDS patients include Pneumocystis pneumonia, tuberculosis, candidiasis, toxoplasmosis, cryptococcus, and cytomegalovirus. Antiretroviral therapy has significantly reduced the rates of opportunistic infections by suppressing HIV and allowing immune recovery. HIV/AIDS remains a major global public health challenge.
Tuberculosis is a chronic infection caused by the bacterium Mycobacterium tuberculosis that primarily affects the lungs. It spreads through the air when people who are sick with TB in their lungs cough, sneeze or spit. Common symptoms include coughing, weight loss, fever and night sweats. Treatment requires taking multiple antibiotics daily for 6-12 months to prevent the development of drug resistance.
This document discusses pulmonary tuberculosis (PTB), a contagious bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs. It outlines three main types of PTB: primary, cavitary, and miliary. Primary PTB occurs when a person is first exposed to the bacteria and may cause a brief fever and cough. Left untreated, primary PTB can develop into cavitary or miliary PTB, which involves the spreading of bacteria through the bloodstream or lungs. Diagnosis involves a contact history, tuberculin skin test, chest x-ray, and sputum examination. Treatment involves a combination of antitubercular drugs over a long period.

Here is the updated list of Top Best Ayurvedic medicine for Gas and Indigestion and those are Gas-O-Go Syp for Dyspepsia | Lavizyme Syrup for Acidity | Yumzyme Hepatoprotective Capsules etc
2. Objectives
• Definition
• Aetiology
• Pathogenesis and pathology
• Clinical presentation
• Investigations
• Types of TB
• Treatment regimens
• Relationship to HIV/AIDS
3. Definition
• A chronic infectious disease caused by
mycobacteria (commonly Mycobacterium
tuberculosis)
• It may affect any organ or tissue but
commonly affects the lungs
4. Aetiology
• Mycobacteria that may produce disease
indistinguishable from that caused by
Mycobacterium tuberculosis include:
M. bovis
M. Leprae
M. kansasii
M. avium
M. intracellulare
5. Mode of transmission
• Transmission occurs by airborne
(infectious droplets).
• The source of infection is a person with
pulmonary-TB who is coughing and is
sputum smear-positive.
6. Note
• Transmission generally occurs indoors.
• Two factors determine an individual’s risk
of exposure:
– The concentration of the droplet in air.
– The length of time somebody breathes
that air.
7. Pathogenesis
• TB may involve any organ but the lungs
are the usual site of primary lesion.
• TB bacilli for lungs is directly related to its
requirement for oxygen for growth
• The inhaled bacilli implants in the distal
airspaces of the lower part of the upper
lobe or the upper part of the lower lobe
8. Cont’d
• TB bacilli lodge within an alveolus:→ rapidly
phagocytized, mostly by alveolar
macrophages.
• Because TB bacilli are resistant to
destruction, they multiply within
macrophages
• Bacilli has naturally slow multiplication
rate, hence appearance of signs and
symptoms may require several weeks.
9. Cont’d
• When the number of TB bacilli becomes
significant, an inflammatory cellular exudate
appears known as the ‘Primary’ or
‘Ghon’s’ focus. Usually the primary focus
heals completely.
• The center undergoes caseous necrosis
• If not: dissemination of TB bacilli from the
focus may follow, probably within hours
• Dissemination is primarily by lymphatics
10. Primary Pulmonary TB
The gray-white parenchymal focus is under the pleura under the
lower part of the upper lobe. Hilar lymph nodes with caseation are
seen on the left
11. Cont’d
• Early extensive lymphangitis and
involvement of hilar lymphnodes
• Involvement of the Primary focus,
lymphangitis and the regional (hilar)
lymphnodes is called Primary complex.
• Cellular immunity develops three to eight
weeks after the initial infection
• Spill over of TB bacilli from lymphatics
into blood stream may occur leading to
seeding of bacilli to other organs → milliary.
12. Cont’d
• Primary complex - caseated areas - heals
in the majority, within few weeks and
undergo calcification
• In some cases: seeding of bacilli advances
→ wide spread disease → death if no
treatment is given.
• NB: at least 20% of calcified primary
lesions contain TB bacilli, initially lying
dormant but can reactivate
15. Clinical feature
• Haemoptysis.
• Chest pain: It is only suggestive of TB if
localized or pleuritic in nature.
• Difficult in breathing.
• Cough of 2 weeks or more
17. Cont’d
• Wasting.
• Respiratory distress: Respiratory rate of
more than 30 breathes per minute is
significant in adults.
• Lymphadenopathy:
• Anterior rather than posterior cervical and
the axillae.
• Generalized lymphadenopathy is more
likely to be HIV related.
21. The Mantoux Test
• Infection with M. Tuberculosis → delayed
hypersensitivity which can be detected by
the tuberculin test (Mantoux)
• A positive tuberculin test does not
differentiate infection and disease but
signifies cell-mediated hypersensitivity to
tubercular antigens
• Induces an induration ≥ 5mm
22. The Mantoux Test
• A false negative result may occur due to
malnutrition, Hodgkin’s lymphoma,
immunosuppression and overwhelming
active TB
• False positives occur in atypical
mycobacteria infections

•CXR: Normal or butterfly
infiltrations.
Kaposi’s sarcoma of the
lungs.
Presence of oral or skin KS
lesions.
29. Tuberculous lymphadenopathy
• The course of lymph node disease is as
follows: (in descending order)
• Firm, discrete lymph nodes.
• Fluctuant nodes matted together.
• Skin breakdown to form ‘collar-stud’
abscess or chronic sinuses.
• Healing with scarring.
31. Miliary-Tuberculosis
• Miliary-TB results from widespread blood-
borne dissemination of TB bacilli.
• This is either the consequence of the
recent primary infection or the erosion of a
tuberculous lesion into a blood vessel.
32. Miliary TB of the spleen. Section
shows numerous gray-white
granulomas
33. Diagnosis
• Hx
• Chest X-ray: Diffuse, uniformly distributed,
small miliary shadows. Miliary means ’like
small millet seeds’.
• Full blood
• Blood culture.

41. First-line anti-TB drugs
Bactericidal drugs:
Isoniazid: (H)
Highly potent Anti-TB drug most effective
against the metabolically active, continuously
growing bacilli.
Mode of action: Inhibitor of mycobacterial cell
wall synthesis.
Common side effects:
Peripheral neuropathy due to pyridoxine
deficiency. Drug-induced hepatitis.
42. Bactericidal drugs:
Rifampicin: (R)
Highly potent Anti-TB drug that can kill the
semi-dormant bacilli (persisters) which
Isoniazid cannot.
Mode of action: Inhibitor of DNA transcription.
Common side effects:
Anorexia, nausea, vomiting and abdominal
pain.
Drug-induced hepatitis.
Reduced effectiveness of oral contraceptive
43. Bactericidal drugs:

48. Introduction
• MDR mycobacterium tuberculosis is a major
and increasing problem in TB treatment and
control
• Resistance to both isoniazid (INH) and
rifampicin (RIF) (Zambia and most parts of the
world)
• INH and RIF are the two most potent
antituberculous drugs. they kill more than 99%
of TB bacilli within 2 months of initiation of
therapy
• Pyrazinamide (PZ) has a high sterilizing effect
acting on semi dormant bacilli
49. Patients at risk of developing MDR TB
• Pts who remain or turn +ve after 4 months of
ATT
• Pts previously treated for TB
• Contact with known MDR pt or one who died
while on DOTS
• Hospital and health care workers
• HIV pts
• Prisoners
50. Types of resistance
Primary:
• infection by mycobacterial strain that is
already resistant to INH and RF
Acquired:
• most prevalent in developing countries
• Development of Resistance in a bacilli that
was previously sensitive to the regular Rx
51. Mechanism of resistance
• Specialized cell wall has significantly
reduced permeability to many compounds
• Modifications by mutations in the drug
target genes leading to an altered target
• Change in the titration (dosage) of the
drugs through overproduction of the target
52. Resistance contd
• MDR TB reflects the stepwise accumulation of
individual mutations in several independent
genes
• Mutations are generally chromosomal
53. Diagnosis of MDR TB
• Drug susceptibility testing (DST)
–Solid media
• Incubation at 35-37 degrees for 8 wks
–Liquid media middle brook 7H09
• Incubation 4-14 days
• PCR
