Child and Adolescent Sports Injuries

Adolescents are fairly active on the sports field. They play contact sports like football, basketball, and hockey. They practise with their teams regularly and are quite likely to end up with minor scrapes and bruises as they pursue their passion. Even non-contact sports such as softball, baseball, track and field can cause physical injuries.

Outlook for Children with Double Inlet Left Ventricle

Double inlet left ventricle (DILV) is a serious congenital heart disease which occurs in approximately 5 to 10 of every 100 000 births.

Symptoms and Causes of Double Inlet Left Ventricle

Double inlet left ventricle (DILV) is a rare condition and its exact etiology is currently unknown. It occurs in 5 to 10 out of 100 000 births. It is suspected to be due to abnormal development of the heart tube during intrauterine life and it leads to the mal-development of heart valves and chambers. As a result, only one heart chamber is actively involved in pumping of blood.

Double Inlet Left Ventricle Diagnosis and Treatment

Congenital heart disease is estimated to occur in about 7 out of every 1000 children born alive. Double inlet left ventricle (DILV) is a very rare condition in which the heart chambers and valves are malformed. It occurs in about 5-10 of every 100 000 babies born alive.

Sources of Iron

Iron is a necessary mineral for the functioning of the body. It is estimated that around 20% of women, 3% of men, and 50% of pregnant women are iron deficient. Symptoms of iron deficiency include fatigue, pallor, and cravings for non-food items like ice or dirt.

Causes of Pulmonary Hypoplasia

Pulmonary hypoplasia is a condition where a baby’s lungs have failed to develop properly during development in the womb. The alveoli, which are needed for the exchange of oxygen and carbon dioxide in the lung, are reduced in number, which affects the baby’s ability to breathe independently after birth. If newborns with pulmonary hypoplasia cannot be supported long enough for new lung tissue to grow, they are at risk of developing lung failure.

Signs and Symptoms of Lead Poisoning

Lead exposure occurs through inhalation of lead dust or fumes or through ingestion of clothing, water or foods that contain the metal. Inhaled or digested lead is released into the blood and then distributed to different parts of the body. Most of the lead builds up and is stored in the bones, which then release it back into the blood, meaning organs are re-exposed long after the initial exposure.

Prevention of Lead Poisoning

Lead is a highly toxic metal. Children under the age of six years are particularly vulnerable to the effects of lead poisoning because it can affect the formation and connection of neurons while the nervous system is growing and developing. No level of lead in the blood has been found to be safe in children and even small amounts can affect children’s ability to learn, concentrate and achieve academically.

Lead Poisoning Pathophysiology

Lead circulates in the body bound to red blood cells. O nly a small fraction is present in the plasma. However, if the level of lead in the blood exceeds 2.9 µmol/L, red cell binding becomes saturated, meaning the fraction of lead in plasma begins to increase. Lead in the plasma gradually gets distributed to various organs and tissues. B ecause the process is slow, it usually takes long-term exposure over months or years before clinical toxicity occurs.

Lead Poisoning, Diagnosis and Treatment

Lead is a very toxic substance that can build up in the body and affect virtually every organ and bodily function. Lead poisoning is usually a chronic disorder and may not present with any acute symptoms. Whether acute symptoms are present or not, lead poisoning eventually leads to permanent and irreversible damage such as cognitive impairment, kidney dysfunction and peripheral neuropathy.

What Happens if You Take Too Much Iron?

Iron is an essential mineral in the diet, and is a crucial component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. Dietary iron is present in two forms. Heme iron is bound within a ring-shaped molecule called porphyrin. It is found mainly in red meat. Non-heme iron is found in both plants and animals. Its absorption is aided by vitamin C.

Iron Deficiency

A deficiency of iron can result from a number of different causes. Inadequate iron in the diet, impaired absorption of iron, and excessive bleeding are all examples of conditions that can lead to iron deficiency.

Ischemic Optic Neuropathy (ION): Overview

Ischemic optic neuropathy (ION) is a condition in which there is significant impairment or loss of vision in the middle-aged or elderly population, especially Caucasians, due to ischemia of the optic nerve head. The incidence in the USA is between 2 and 10 per 100 000 with 6000 new cases being diagnosed each year.

Pulmonary Embolism (PE): Overview

A pulmonary embolism (PE) is a potentially fatal blockage of an artery in the lungs. The nature of the blockage is typically a blood clot, fat agglomeration, bubble of gas, or a piece of foreign material, known as an embolus.
