GERD in children may cause repeated vomiting, effortless spitting up, coughing, and other respiratory problems, such as wheezing. Inconsolable crying, refusing food, crying for food and then pulling off the bottle or breast only to cry for it again, failure to gain adequate weight, bad breath, and burping are also common. Children may have one symptom or many; no single symptom is universal in all children with GERD. Of the estimated 4 million babies born in the US each year, up to 35% of them may have difficulties with reflux in the first few months of their lives, known as spitting up. About 90% of infants will outgrow their reflux by their first birthday. Mouth
Acid reflux into the mouth can cause breakdown of the enamel, especially on the inside surface of the teeth. A dry mouth, acid or burning sensation in the mouth, bad breath and redness of the palate may occur. Other not so common symptoms of GERD include difficulty in swallowing, water brash which is flooding of the mouth with saliva, chronic cough, hoarse voice, nausea and vomiting.Signs of enamel erosion are the appearance of a smooth, silky-glazed, sometimes dull, enamel surfaces with the absence of perikymata, together with intact enamel along the gum margin. It will be evident in people with restorations as tooth structure typically dissolves much faster than the restorative material, causing it to seem as if it “stands above” the surrounding tooth structure.
As seen at Chernobyl, when skin is irradiated with high energy beta particles, moist desquamation (peeling of skin) and similar early effects can heal, only to be followed by the collapse of the dermal vascular system after two months, resulting in the loss of the full thickness of the exposed skin. Another example of skin loss caused by high-level exposure of radiation is during the 1999 Tokaimura nuclear accident, where technician Hisashi Ouchi had lost a majority of his skin due to the high amounts of radiation he absorbed during the irradiation. This effect had been demonstrated previously with pig skin using high energy beta sources at the Churchill Hospital Research Institute, in Oxford. Cause
ARS is caused by exposure to a large dose of ionizing radiation (> ~0.1 Gy) over a short period of time (> ~0.1 Gy/h). Alpha and beta radiation have low penetrating power and are unlikely to affect vital internal organs from outside the body. Any type of ionizing radiation can cause burns, but alpha and beta radiation can only do so if radioactive contamination or nuclear fallout is deposited on the individuals skin or clothing. Gamma and neutron radiation can travel much greater distances and penetrate the body easily, so whole-body irradiation generally causes ARS before skin effects are evident. Local gamma irradiation can cause skin effects without any sickness. In the early twentieth century, radiographers would commonly calibrate their machines by irradiating their own hands and measuring the time to onset of erythema.
