Spinal tuberculosis can lead to serious deformities and neurological deficits if left untreated. It is most commonly caused by hematogenous spread from the lungs. Diagnosis involves clinical history, imaging studies like x-rays and MRI, and laboratory tests. Treatment consists of a combination of chemotherapy for at least 18 months and surgery if indicated to decompress the spinal cord and correct deformities. With early detection and proper management, spinal tuberculosis can be cured with good long-term outcomes.
Deformity: It’s the position of a limb/Joint, from which it cannot be brought back to its normal anatomical position.

Multidrug ATT is essential, as varying categories of bacilli
exist in a lesion. They may exist as intracellular, extracellular,
dormant, or rapidly multiplying forms and each has different
growth and metabolic properties.69 In addition, multidrug ATT
reduces instances of drug resistance.70 The duration of chemotherapy for spinal TB has been long debated, and the WHO
recommends 9 months of treatment where 4 drugs—isoniazid,

Spinal TB usually is insidious in onset and the disease progresses at a slow pace.22 The diagnostic period, since onset
of symptoms, may vary from 2 weeks to several years. The
manifestation of spinal TB depends on the severity and duration of the disease, site of the disease, and the presence of
complications such as abscess, sinuses, deformity, and neurological deficit.23 Spinal TB can either be complicated or
uncomplicated. In complicated TB, patients present with deformity, instability, and neurological deficit. Uncomplicated

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

2. INTRODUCTION
• Evidence of spinal TB - in 5000-year-old mummies.
• In 1779, Percival Pott published -spinal TB.
• Tuberculosis is the chronic consumptive disease and
currently world’s leading cause of death.
• Tuberculous spondylitis is the most dangerous form
of skeletal TB.
3. Epidemiology
• One fifth of TB population is in India
• 3% are suffering from skeletal TB
• Vertebral TB - 50% of all cases of skeletal TB
• Almost 50% are from pediatric group
• Every day 1000 die of tuberculosis in India
4. There were an estimated 10.4 million new cases of TB
disease in 2015.
In 2015 an estimated 1.4 million people who were
died of TB.
Bangladesh ranked 5th
in 2012 (WHO)
Bangladesh ranked 7th
according to total cases of
incidence. (2,09,438 in 2015)
TB (Global Scenario)TB (Global Scenario)
7. PATHOLOGY
• Spinal tuberculosis is usually a secondary
• Hematogenous in origin
• Usually involves 2 adjacent vertebrae
• Delayed hypersensitivity immune reaction
• Initially : a pre-pus inflammatory reaction, with
Langerhan’s giant cells, epithelioid cells, and
lymphocyte
• The granulation tissue proliferates, producing
thrombosis of vessels
8. PATHOLOGY
• Tissue necrosis, tubercle formation result in paraspinal abscess
• The pus may be localized, or it may track along tissue planes
• Progressive necrosis of bone leads to a kyphotic deformity
• Typically, the infection begins in the anterior aspect of the
vertebral body adjacent to the disk
• The infection then spreads to the adjacent vertebral bodies under
the longitudinal ligaments
• Noncontiguous (skip) lesions are also seen occasionally
9. Pathology of spinal TB
• Can loose complete vertebrae
• Wedge shaped fractures are common
15. HISTORY
• Presentation depends on :
- Stage of disease,
- Site
- Presence of complications such as neurologic deficits,
abscesses, or sinus tracts
• Average duration of symptoms at the time of diagnosis
is 3 – 4 months.
• Back pain is the earliest & most common symptom
• Constitutional symptoms
• Neurologic symptoms (50 % of cases).
16. Lab studies
• Mantoux / Tuberculin skin test ( purified protein derivative {PPD})
• A positive test can be observed, one to 3 months after infection.
Positive in 84 – 95 %
Negative in almost 20 per cent patients with active disease if the
disease is disseminated, or if the patient is immunocompromised or
suffering from exanthematous fever
17. .
• ESR usually elevated (neither specific nor reliable).
• ELISA : sensitivity 60 – 80%
• ALS: anti-lymphocyte serum
18. • There are three diagnostic non- culture laboratory tests:
1. Immunological tests ( antigen & antibody)
2. Metabolic product detection test ( extra-corporeal IFN-y
test)
3. Amplification of DNA of M. Tuberculosis by PCR.
• Other than these
• - ELISA technique & T- SPOT Using 6 kDa & 10 kDa.
• - Xene expert for MDR TB.
DIAGNOSIS
Recent advance
19. • The major non-culture molecular diagnostic test, PCR
Amplifies the DNA of M. tuberculosis
Provide result within hour
Monitor responses to treatment
Provide rapid information on drug resistance & clonality.
DIAGNOSIS
Recent advance
20. Microbiology studies to confirm diagnosis :
• Ziehl-Neelsen staining: a quick and inexpensive method
• Obtain bone tissue or abscess samples to stain for acid-fast
bacilli (AFB), & isolate organisms for culture & drug
susceptibility
• Culture results are available only after a few weeks
• Histopathology
21. Radiological diagnosis
1. Plain radiograph
2. CT scan
3. MRI spine
4. Bone scan
TB bacilli are rarely found in CSF, therefore imaging plays a vital
role in suggesting the diagnosis.
22. EXTRA -DURAL INVOLVEMENT
• The primary focus of infection in the spine can be either in the vertebral
body or in the posterior elements.
• Four patterns :
- Paradiscal ( Commonest)
- Central
- Anterior, &
- Appendiceal
Radiological diagnosis
35. • The three main causes of Pott’s paraplegia are:
1) cord compression by abscess and granulation tissue;
2) cord compression by sequestrums and the posterior bony
edge of the vertebral body at the level of the kyphosis; and
3) Bony canal stenosis of the deformed spine above the
level of the kyphosis.
Pott’s Paraplegia
36. Factors affect recovery from Pott’s paraplegia.
• 1. Patient’s general physical condition and age;
• 2. Condition of the spinal cord; level and number of
vertebrae involved;
• 3. Duration and severity of the paraplegia;
• 4. Time to initiation of treatment.
Pott’s Paraplegia
37.
38. Tuli and Kumar’s Staging of Pott’s Paraplegia ::
Stage I :Patient unaware of neural deficit, physician
detects plantar extensor and/or ankle clonus.
Stage II : Patient aware of deficit but manages to walk
with support, clumsiness of gait.
Stage III : Paralysis in extension, sensory deficit less
than 50%
Stage IV : III + flexor spasm/ paralysis in flexion/ flaccid/
sensory deficit more than 50%/ sphincters involved.
39. Treatment should be individualized according to
different indications which is essential to recovery.
Treatment outcome of secondary TB is not as good as
primary.
In case of early diagnosis, outcome is very good. But in
our perspective, patient present very late with
complications partly due to ignorance and partly due to
delay in the diagnosis. So result is not always very
rewarding.
TREATMENT OF POTT’S DISEASETREATMENT OF POTT’S DISEASE
41. • Primary goal:
Eradicate the infection and to save life.
• Secondary goal:
Provide stability for the affected spine.
To meet patient’s aesthetic demand.
To prevent or treat paralysis.
Current views: Healing of the lesion with near normal spine
44. ConservativeConservative
•In early presentation with minimal to moderate bony
involvement that does not seem to cause noticeable
deformity.
Can be given on an ambulatory basis without bracing.
Delayed and/or less neurological recovery.
45. ResponseResponse
There are no clear-cut definitions of good (or rapid)
response, poor (or slow) response and non-response.
The recommended observation period for drug response
in non-paralytics, a 6- to-8-week (maximum 3 months)
whereas in paralytics the assessment should take 3 to 4
weeks.
46. Advantages of surgical treatment :
Early healing
Histological confirmation
Reduction of late-recurrence rates
Correction and/or prevention of deformity
Early effective neurological recovery
To meet the patient aesthetic demands
