Pulmonary tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis (M. tuberculosis). TB is contagious. This means the bacteria is easily spread from an infected person to someone else. You can get TB by breathing in air droplets from a cough or sneeze of an infected person. The resulting lung infection is called primary TB.
Most people recover from primary TB infection without further evidence of the disease. The infection may stay inactive (dormant) for years. In some people, it becomes active again (reactivates).
Most people who develop symptoms of a TB infection first became infected in the past. In some cases, the disease becomes active within weeks after the primary infection.

Fibrotic scar in CXray may suggest an old TB that may stay dormant as the body immune system has enveloped the bacteria in one spot. The spot may still have the possibility to cause infection (latent TB). Therefore, ppl with 5mm TST should be treated for LITB

When I think about Macrolides, I think about 'Macklemore' singing the Thrift shop song which is good for everything (Chlamydia, Streptococcus, Mycoplasma, Haemophilius, and even the dreaded Legionella pneumonia). However, it ain't good for high-scale stuff like DRSP (Drug-resistant streptococcus Pneumoniae).
Also, remember that macrolides work on the ribosomes, therefore it ain't dependent on cell-wall. Thus, it works against small tiny bacteria such as Chlamydia & Mycoplasma.
Seriously, when we think of macrolides, we practically only use Z-Pack (azithromycin) as erythromycin has too much side effects and only useful for ointment.

Bacteria is usually easy to kill because they can easily be invaded with meds that flood them whereas virus is harder to kill bc of their lack of cells (non-living organisms).

The Modified Medical Research Council Dyspnea Scale - MMRC
The Modified Medical Research Council Dyspnea Scale, or MMRC, uses a simple grading system to assess a patient's level of dyspnea -- shortness of breath.
This scale doesn't define the sensation of breathlessness per se, but rather the degree of disability that such breathlessness poses on day-to-day activities.
The scale measures a broad range of disability due to dyspnea, from only mild limitations, up to severe limitations, and is an easy and rapid test to do.
In general, this scale correlates fairly well with objective measures of breathing such as pulmonary function tests and walk tests. It also tends to be stable over time which is good in having an objective measure.
MMRC Dyspnea Scale
| Grade | Description of Breathlessness |
|---|---|
| 0 | I only get breathless with strenuous exercise. |
| 1 | I get short of breath when hurrying on level ground or walking up a slight hill. |
| 2 | On level ground, I walk slower than people of the same age because of breathlessness or have to stop for breath when walking at my own pace. |
| 3 | I stop for breath after walking about 100 yards or after a few minutes on level ground. |
| 4 | I am too breathless to leave the house or I am breathless when dressing. |

If theFEV1/FVC ratio is <80%, it indicates that an obstructive defect is present.
Asthma is defined as a reversible obstructive defect. Therefore, a patient with an FEV1/FVC ratio < 80% can be given a bronchodilator (i.e. albuterol) and the spirometry can be repeated. If the FEV1 increases by more than 12%, it is indicative of reversible airway disease. If the FEV1 does not increase by more than 12%, it is considered nonreversible or fixed airway disease(i.e. COPD). Because asthma is a reversible obstructive defect, the spirometry may be normal at the time of evaluation. In instances where asthma is strongly considered yet the spirometry is normal, a methacholine challenge may be needed. In this test, a patient inhales one or more concentrations of methacholine, and results of spirometry before and after the inhalations are measured. The amount of methacholine needed to elicit a drop of 20% in the FEV1 (known as the PD20) is obtained. The lower the PD20, the more likely that the patient has reactive airways. The reader is directed elsewhere for a more complete review of methacholine testing.

Figure 5 - Quick interpretation of spirometry
- Are the patient's age, weight, and height correct?
- Is the effort acceptable? (based on lab technician comments and adequate volume time curve)
- Is an obstructive defect present (FEV1/FVC < 80%)
- If an obstructive defect is present, how severe is it
- FEV1 > 80% predicted = minimal
- FEV1 65 – 80% predicted = mild
- FEV1 50 - 65% predicted = moderate
- FEV1 < 50% = severe
- Does the shape of the curve suggest where the obstruction might be? (variable intrathroacic/extrathoracic, fixed)
- Is an early obstructive defect of the small airways present? (FEF 25-75 < 60%)
- Is a restrictive defect suggested? (FVC < 80% predicted
The FEV1/FVC ratio, also called Tiffeneau-Pinelli index,[1] is a calculated ratio used in the diagnosis of obstructive and restrictive lung disease.[2][3] It represents the proportion of a person's vital capacity that they are able to expire in the first second of forced expiration.[4]
Normal values are approximately 80%.[5] Predicted normal values can be calculated online and depend on age, sex, height, mass and ethnicity as well as the research study that they are based upon.
A derived value of FEV1% is FEV1% predicted, which is defined as FEV1% of the patient divided by the average FEV1% in the population for any person of similar age, sex and body composition.

FVC (forced vital capacity) is the volume of air that can be maximally forcefully exhaled - and therefore contains the FEV1 within it.

All of the nutrients that come from food and supplements don't get absorbed in the same place; they're absorbed in various places in your gastrointestinal tract. Below are the rest stations where nutrients get absorbed along the body's GI tract. Because food pulls over at various spots in the intestinal tract, disease in these areas can cause nutritional deficiencies, even if we are eating the right foods.
- Stomach: Alcohol.
- Duodenum: First part of the small intestine (takes off from the stomach): Calcium, magnesium, iron, fat-soluble vitamins A and D, glucose.
- Jejunum: Middle part of the small intestine: Fat, sucrose, lactose, fat-soluble vitamins A and D, water-soluble vitamins like folic acid, proteins and amino acids, glucose.
- Ileum: Last part of the small intestine (leads to large bowel): Proteins and amino acids, water-soluble vitamins like folic acid, vitamin B12.
- Colon: (also known as the large bowel): Water, potassium, sodium chloride, fatty acids from fiber digestion.

Mineral oils is fat. Therefore, fat-soluble vitamins A,D,E,K is absorbed by this mineral oil in the intestinal lumen and gets excreted out from the body. Fat-soluble vitamins are absorbed mostly in the terminal ileum as illustrated in the below.

Hypertrophied anal papillae are benign growths of connective tissue that are covered by squamous cells. They are simply enlarged normal papillae, which are small folds of mucosa found at the dentate line. Hypertrophied anal papillae are also called fibroepithelial polyps.

What is the mucosa?
A mucous membrane or mucosa is a membrane that lines various cavities in the body and surrounds internal organs
S3, S4:
S3&S4 are lower frequency heart sounds compared with S1&S2. Therefore, it's best heard with the bell of the stethoscope at the apex when pt on the left side in order to bring the heart closer to the surface.
S3 occurs when the chordae tendonae are so tense due to rapid fluid overload filling during diastole. The tense chordae tendonae causes the S3 sound right after the S2 sound (the closure of the semilunar valves).
S3 is normal in children and athletes. It simply means the ventricle is capable of expanding and get more fluid.
S3 is pathologic in middle-aged and older people because it signifies fluid overload (CHF)
S4 occurs when the atrium tries to fill the thick-walled ventricle. This is always pathologic.
