The observation Somner make from the survey data of night blind children in Indonesia is that children with "mild" xerophthalmia (night blindness, Bitot's spots) died at far higher rates than their nonxerophthalmic peers.
Xerophthalmia ("xērós" meaning "dry" and "ophthalmos" meaning "eye") is a medical condition in which the eye fails to produce tears. It may be caused by vitamin A deficiency, which is sometimes used to describe that condition, although there may be other causes.
The damage to the cornea in vitamin A associated xerophthalmia is quite different from damage to the retina at the back of the globe, a type of damage which can also be due to lack of vitamin A, but which is caused by lack of other forms of vitamin A which work in the visual system. Xerophthalmia from hypovitaminosis A is specifically due to lack of the hormone-like vitamin A metabolite retinoic acid, since (along with certain growth-stunting effects) the condition can be reversed in vitamin A deficient rats by retinoic acid supplementation.(however the retinal damage continues)
Cause :
The condition is not congenital and develops over the course of a few months as the lacrimal glands fail to produce tears. Other conditions involved in the progression already stated include the appearance of Bitot's spots, which are clumps of keratin debris that build up inside the conjunctiva and night blindness, which precedes corneal ulceration and total blindness.
Treatment :
Treatment can occur in two ways: treating symptoms and treating the deficiency. Treatment of symptoms usually includes the use of artificial tears in the form of eye drops, increasing the humidity of the environment with humidifiers, and wearing wraparound glasses when outdoors. Treatment of the deficiency can be accomplished with a Vitamin A or multivitamin supplement or by eating foods rich in Vitamin A. Treatment with supplements and/or diet can be successful until the disease progresses as far as corneal ulceration, at which point only an extreme surgery can offer a chance of returning sight.

______ is premature separation of the placenta from the uterine wall prior to delivery.
Placental abruption or abruptio placentae is premature separation of the placenta from the uterine wall prior to delivery.
Before giving birth, placental abruption happens when the placenta separates from the uterus' inner wall. A placental abruption can deprive the infant of oxygen and nourishment while also leaving the mother with severe bleeding.
When the vascular structures sustaining the placenta are compromised, placental abruption results. In other words, the vascular networks that connect the placenta's maternal side to the uterine lining are severed. The fetus receives oxygen and nutrients from these vascular systems. When the vascular structures are damaged due to hypertension, substance abuse, or disorders that cause the uterus to stretch, the vascular network may become disrupted. The placenta is less elastic than the uterus despite being a muscle like the uterus. As a result, when the uterine tissue suddenly extends, the placenta stays stable while the vascular system that connects the uterine wall to the placenta tears.

Why do both high levels and very low levels of insulin lead to increased eating?.
Both high levels and very low levels of insulin lead to increased eating because little glucose is reaching the cells to be used as fuel.
How do insulin levels affect apatite?
Cells will absorb too much glucose from the blood if a person's insulin level rises over what is necessary, such as when they spend more energy than expected or eat less than they had planned. An abnormally low blood glucose level (hypoglycemia) results from this . As a response to hypoglycemia, the body releases liver-stored glucose in an effort to restore normal blood sugar levels. Elevated insulin levels result in greater appetite, enhanced enjoyment of sweet tastes, and higher food intake.
Type 1 diabetics either produce very little insulin or none at all. This illness is brought on by the beta cells' inability to produce insulin due to antibody destruction (antibodies are typically molecules the body releases to fight infections). High blood glucose levels result from the body's inability to transport glucose from the blood into the cells when there is insufficient insulin in the body. If the glucose is not reaching the cells, the person will eat more.
