Down Syndrome, Fanconi anemia and Bloom syndrome.
pathophysiology of leukemia
Malignant leukemia cells arise from precursor cells in blood-forming elements.
These cells can accumulate and crowd our normal bone marrow elements, spill peripheral blood, and eventually invade all body organs and tissues.
Replacement of normal hematopoietic elements by leukemic cells results in bone marrow suppression, which is marked by a decreased production of RBCs, normal WBCs, and platelets.
Bone marrow suppression results in anemia from decreased RBC production, predisposition to infection due to neutropenia, and bleeding tendencies due to thrombocytopenia. These put the child at risk of death from infection or hemorrhage.
Infiltration of reticuloendothelial organs (spleen, liver, and lymph glands) causes marked enlargement, and eventually, fibrosis.
Leukemic infiltration of the CNS results in increased intracranial pressure (ICP) and other effects, depending on the specific areas involved.
Other possible sites of long-term infiltration include the kidneys, testes, prostate, ovaries, GI tract, and lungs.
The hypermetabolic leukemic cells eventually deprive all body cells of nutrients necessary for survival. Uncontrolled growth of leukemic cells can result in metabolic starvation.

why we do not palpate the abdomen?
Do not palpate the abdomen – doing so can rupture the encapsulated tumor and cause dissemination of the disease to adjacent and distant sites.

Pathophysiology of asthma
the following manner.
a. There is an initial release of inflammatory mediators from bronchial mast cells, epithelial cells, and macrophages, followed by activation of other inflammatory cells.
b. Alterations of autonomic neural control of airway tone and epithelial integrity occur and the increased responsiveness in airway smooth muscle results in clinical manifestations (wheezing and dyspnea).
2. Three events contribute to clinical manifestations.
a. Bronchial spasm
b. Inflammation and edema of the mucosa
c. Production of thick mucus, which results in increased airway resistance, premature closure of airways, hyperinflation, increased work of breathing, and impaired gas exchange.
3. If not treated promptly, status asthmaticus – an acute, severe, prolonged asthma attack that is unresponsive to the usual treatment – may occur, requiring hospitalization.

Pathophyisiology of UTI
Pathophysiology
1. In an uncomplicated UTI, inflammation usually is confined to the lower urinary tract. Recurrent cystitis, however, may produce anatomic changes in the ureter that lead to vesicoureteral valve incompetence and resultant urine reflux. This provides organisms with access to the upper urinary tract.
2. Pyelonephritis usually results from an ascending infection from the lower urinary tract. It can lead to acute and chronic inflammatory changes in the pelvis and medulla, with scarring and loss of renal tissue.
3. Recurrent or chronic infection results in increased fibrotic tissue and kidney contraction
Clinical manifestation of infants with UTI
Infants may exhibit irritability, constant squirming, fever or hypothermia, jaundice, weight loss, FTT, vomiting and diarrhea, diaper rash, and an abnormal urinary stream.

is a chronic metabolic disorder that results from either a partial or complete deficiency of insulin
DM
Is characterized by pancreatic beta cells destruction leading to absolute insulin deficiency
Type 1 DM
usually results from insulin resistance
Type 2 DM
is the most common endocrine disease of childhood.
Type 1 DM
Long term complications of DM
nephropathy, retinopathy, and neuropathy. Altered thyroid functioning is frequently noted in children with diabetes.
is an autoimmune disease that develops when a genetically pre-disposed child is exposed to a precipitating factor, such as a viral infection.
Type 1 DM
Pathophysiology of DM
- Insulin is needed to support carbohydrate, protein, and fat metabolism, primarily to facilitate entry of these substances into cells.
- Destruction of 80% to 90% of the pancreatic beta cells results in a clinically significant drop in insulin secretion.
- This loss of insulin, the major anabolic hormone, leads to a catabolic state characterized by decreased glucose used, increased glucose production, and inability to store glycogen, eventually resulting in hyperglycemia.
- In a state of insulin deficiency, glucagon, epinephrine, GH, and cortisol levels increase, secondary to fat breakdown, stimulating lipolysis, fatty acid release, and ketone production.
- A persistent blood glucose concentration above 180 mg/dl results in glycosuria, leading to osmotic diuresis with polyuria and polydipsia.
- Excessive ketone production can cause diabetic ketoacidosis (DKA), an acutely life-threatening condition characterized by marked hyperglycemia, metabolic acidosis, dehydration, and altered level of consciousness ranging from lethargy to coma.

is a systemic inflammatory disease that occurs as a result of naturally acquired immunity to group A beta-hemolytic streptococcal infection. There is cardiac involvement in about 50% of cases.

usually occurs 2-6 weeks after an untreated upper respiratory infection with group A beta-hemolytic streptococci
It is believed that a genetic susceptibility to RF is associated
with a state of immune hyperactivity to the streptococcal antigens
Exact etiology is unknown
rheumatic fever
pathophysiology of RF?
- The child becomes infected with group A beta-hemolytic streptococcal bacteria.
- Antibodies formed against these bacteria begin to attack the connective tissue of the body, producing inflammation, which affects the heart, joints, central nervous system and subcutaneous tissue.
- Cardiac involvement is characterized by carditis.
a. A type of lesion, called an Aschoff body (a proliferating, fibrin-like plaque), forms on the heart valve causing edema and inflammation.
b. When the healed area becomes fibrous and scarred, the valve leaflets fuse (stenosis), causing inefficiency and leakage.
c. The mitral and aortic valves are affected most often.
