Jellyfish are free-swimming, non-aggressive, gelatinous marine animals surrounded by tentacles. These tentacles are covered with sacs (nematocysts) that are filled with poison (venom) that can cause a painful to sometimes life-threatening sting. The marine animals included in the “family” are jellyfish, box jellyfish (sea wasps), Portuguese man-of-war, hydroids, anemones, and fire coral. Jellyfish are found throughout the world. But, the most deadly are found in the Indo-Pacific and Australian waters.
Hoarseness is a general term which describes abnormal voice changes. Hoarseness is a huskiness of voice. It is due to irritation of the vocal cords. Hoarseness may take several forms, including a breathiness, raspiness, strain of the voice, or changes in loudness or the tone of the voice. However, when speaking or singing, the vocal cords are brought together, essentially narrowing the air flow and vibrating, producing sound.
Also known as aphthous ulcers, canker sores are small sores that can occur inside the mouth, cheeks, lips, throat, or sometimes on the tongue. But don’t confuse canker sores with cold sores or fever blisters, which are sores that are caused by the herpes simplex virus and are found outside the mouth around the lips, on the cheeks or chin, or inside the nostrils. Whereas cold sores are contagious, canker sores are not contagious — so kissing cannot spread them.
A burn is damage to the skin or tissues caused by contact with an electrical current or a hot source. Burns can be classified as First,Second, Third and Fourth degrees. First-degree burns involve only the outer layer of skin, which is the epidermis. These burns usually appear red and swollen. There is no blistering with first-degree burns. These burns usually heal within 3-6 days without permanent scarring. Second-degree burns involve the epidermis and some or all of the dermis.
Every individual has a characteristic odor on the body, which is caused due to several factors. Chiefly these odors are caused due to the presence of bacteria on the body of the person. These bacteria multiply in the presence of sweat. This is when the odor becomes strong enough to become offensive.
Although many different types of insects in the United States are able to inflict a poisonous bite or sting (meaning they are venomous), the insects most likely to cause medical problems are bees (including the domestic honey bee, its Africanized “killer bee” race, and the bumble bee), wasps (including paper wasps, hornets, and yellow jackets), and ants (including the fire ant). These insects are all in the Hymenoptera order, and thus stings from them are occasionally called Hymenoptera stings.
