anaemia | classification | clinical feature(sign and symptom)

              ANAEMIA.

defination-It is defined as a state in which the blood haemoglobin level is below the normal range.

normal in adult is between 13-16 g/dL in males 

                                       11.5-15.0 g/dL in females.

clssification 

by 2 ways

anaemias can be classified in two ways:

1. Based on the cause of anaemia.

2. Based on the morphology of red cells.

--Based on the cause of anaemia

• Blood loss, which may be acute or chronic

• Acute (large volume over short period)

• Chronic (small volume over long period)

• Inadequate production of normal red cells

• Excessive destruction of red cells

--Based on the morphology of red cells

• Normocytic

• Microcytic

• Macrocytic

etiology.

*Due to blood loss

 *Due to less production of normal red cells

*Due to more destruction of red cells

clinical feature 

symptoms------

Fatigue

lassitude

dyspnoea

palpitation

Irritability

sleep disturbances

lack of concentration.

 headache 

tinnitus 

vertigo

sign

.Pallor of skin palms, oral mucous membrane, nail beds.

 Tachycardia

 wide pulse pressure.

Oedema.

Cervical venous hum

 hyperdynamic precordium 

Ejection systolic murmur 

Cardiac dilatation 

bronchial asthma

BRONCHIAL ASTHMA

It is defined as of dyspnoea, cough, chest tightness and wheezing, that vary over time and in intensity, together with variable expiratory airflow limitation. that result with narrowing of airway

Asthma is usually associated with bronchial hyper-reactivity

classification

early onset 

late onset

etiopathogenesis

1. Bronchialhyper-responsiveness.

2. Inflammatory reaction in bronchial wall 

cells involves in release of mediaters

Mast cells

• Macrophages

• Eosinophils

• Lymphocytes

mediaters are

Histamine

• Prostaglandins (PGD2, PGF2a and PGE2) 

• Thromboxane

Leucotrienes 

• Platelet activating factor 

• Bradykinin

• TNF-cx, IL-4, IL-5

Investigations------

Chest radiography:

Pulmonary function tests

abg

Skin hypersensitivity tests

Elevated serum IgE levels.

managment------

3-adrenoreceptoragonists.

 Methylxanthines.

 Corticosteroids.

 Chromones.

 Anticholinergics.

 Leucotriene inhibitors.

ENTERIC FEVER

Enteric fevers include typhoid fever caused by Salmonella typhi (or known as Salmonella enterica serovar Typhi) 

The incubation period of typhoid fever is about 10–14 days

These organisms are transmitted by faecal-oral route, usually by carriers, often food handlers, through contaminated food milk water

Clinical Features

The disease usually presents with fever associated with headache, malaise and chills.

temperature to 40-41°C ("step-ladder" pattern) is seen in some cases. 

Early intestinal manifestations include constipation, especially in adults or mild diarrhoea in childs

The characteristic rose spots or "rose-red spots" may be seen on the chest and abdomen during the Ist week 

Intestinal complications may  occur in the 3rd or 4th week of illness.

treatment --------

general bed rest fluids intake 

antibiotics therapy

amoxicillin 

ciprofloxqcin

cefixime

azithromycine

aztreonam

prevention -------

good hygiene 

proper sewage 

proper disposibel

drink clean water 

vaccine ty21a live attenuated for s.typhe

-liver may inlarge 

2 critical phase

after defervescence of fever an inc. in capillary permeability along with inc haematocrit level may occure this begain of crital phase the degree of inc above the baseline haemotocrit reflect severty of plasma leakage

-shock may  occur

SHOCK

defination _state in which sevior reduction in tissu perfusion leads first to irreversable and then to irreversable cell injury it is due to inadiquate oxygen supply to cells

Classification

2 cardoogenic shock (causes-acute mi, acute mitral regurgitation, cardiomyopathy, cardic tumer)

3 neurogenic shock (causes-head injury, spinal injury etc)

4 anaphylatic shock (causes-dugs ,insects bite etc)
