Congenital adrenal hyperplasia caused by 11beta-hydroxylase deficiency

11Beta-hydroxylase (CYP11B1) deficiency involves defective production of cortisol, with accumulation of mineralocorticoid precursors, resulting in hypernatremia, hypokalemia, and hypertension and increased production of adrenal androgens, leading to virilization. Diagnosis is by measurement of cortisol, its precursors, and adrenal androgens and sometimes by measuring 11-deoxycortisol after adrenocorticotropic hormone administration. Treatment is with a corticosteroid (1, 2).
11Beta-hydroxylase deficiency causes about 5 to 8% of all cases of congenital adrenal hyperplasia. Conversion of 11-deoxycortisol to cortisol and deoxycorticosterone to corticosterone is partially blocked, leading to

Increased levels of adrenocorticotropic hormone (ACTH)
Accumulation of 11-deoxycortisol (which has limited biological activity) and deoxycorticosterone (which has mineralocorticoid activity)
Overproduction of adrenal androgens (dehydroepiandrosterone [DHEA], androstenedione, and testosterone )

It is a long, slender, and fast-moving snake, identified by its distinctive stripes running down the length of its body. They primarily feed on lizards and small rodents. The scientific name for this species is Masticophis lateralis.

Iron (Fe) is a component of hemoglobin, myoglobin, and many enzymes in the body. Heme iron, contained mainly in animal products, is absorbed much better than nonheme iron (eg, in plants and grains), which accounts for gt; 85% of iron in the average diet. However, absorption of nonheme iron is increased when it is consumed with animal protein and vitamin C.
(See also Overview of Mineral Deficiency and Toxicity.)
Iron deficiency is one of the most common mineral deficiencies in the world. It may result from the following:

Inadequate iron intake, common in infants, adolescent girls, and pregnant women
Malabsorption (eg, celiac disease)
Chronic bleeding, including heavy menses and bleeding from gastrointestinal lesions (eg, tumors)

Chronic bleeding due to colon cancer is a serious cause in middle-aged people and the elderly.
Iron deficiency and iron deficiency anemia are common among elite runners and triathlon athletes (1).
When deficiency is advanced, microcytic anemia develops.
In addition to anemia, iron deficiency may cause pica (a craving for nonfoods) and spoon nails and is associated with restless leg syndrome. Rarely, iron deficiency causes dysphagia due to postcricoid esophageal web.
Diagnosis of iron deficiency involves complete blood count, serum ferritin and iron levels, and possibly measurement of transferrin saturation (iron-binding capacity). In deficiency states, iron and ferritin levels tend to be low, and iron-binding capacity tends to be high.
Rarely, when the diagnosis of iron deficiency remains uncertain, examination of bone marrow for iron may be necessary.
Treatment of iron deficiency involves correcting the cause if possible (eg, treatment of a bleeding intestinal tumor). All people with moderate or severe iron deficiency and some people with mild deficiency require iron supplementation.

Leukocyte adhesion deficiency results from an adhesion molecule defect that causes granulocyte and lymphocyte dysfunction and recurrent soft-tissue infections.
(See also Overview of Immunodeficiency Disorders and Approach to the Patient With an Immunodeficiency Disorder.)
Leukocyte adhesion deficiency is a primary immunodeficiency disorder that involves phagocytic cell defects. Inheritance is autosomal recessive.
Leukocyte adhesion deficiency is caused by deficiency of adhesive glycoproteins on the surfaces of white blood cells (WBCs); these glycoproteins facilitate cellular interactions, cell attachment to blood vessel walls, cell movement, and interaction with complement fragments. Deficiencies impair the ability of granulocytes (and lymphocytes) to migrate out of the intravascular compartment, to engage in cytotoxic reactions, and to phagocytose bacteria. Severity of disease correlates with degree of deficiency.
Three different types of syndromes have been identified:

Leukocyte adhesion deficiency 1: Deficient or defective beta-2 integrin family
Leukocyte adhesion deficiency 2: Absent fucosylated carbohydrate ligands for selectins
Leukocyte adhesion deficiency 3: Defective activation of all beta integrins (1, 2, and 3)

Type 1 results from mutations in the integrin beta-2 gene (ITGB2), encoding CD18 of beta-2 integrins. Type 2 results from mutations in the glucose diphosphate (GDP)-fucose transporter gene. Type 3 is caused by mutations in the FERMT3 gene (11q13.1), which encodes kindlin-3 in hematopoietic cells.

Vitiation refers to the action of spoiling, impairing, corrupting or making something ineffective, typically in the context of legal contracts or agreements. A contract, for instance, can be vitiated if there was a mistake, misrepresentation or fraud involved in its formation, rendering it invalid or unenforceable. In broader terms, vitiation can also refer to the process of corruption or degradation.
