Abstract:
The umbilical cord, a vital conduit between the placenta and the fetus, loses much of its significance after birth. However, newborns can often present with various abnormalities of the umbilicus, such as benign granulomas or more serious lesions due to persistent remnants, many of which can change the normal course of cord separation and may be associated with significant morbidities if left unrecognized and uncorrected. Although not uncommon, sanguineous drainage from the umbilical stump can be quite alarming to new parents. Parental counseling regarding normal umbilical cord changes, as well as abnormal findings, such as discharge and skin changes, are important for the recognition and timely treatment of potentially significant umbilical cord disorders.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
