Amebiasis is an ailment caused by a one-celled parasite named Entamoeba histolytica. Entamoeba histolytica is an ameba, a type of single-celled animal that propagate by simple division and occupies around in the intestine, scavenging for small morsels of food and bacteria. Trophozoites generally lives in the large intestine without causing any evidence at all, but every now and then they invade the lining of the large intestine, causing intestinal disease (called intestinal amebiasis ).

Amebiasis occurs most commonly in areas where living conditions are crowded, with insufficient sanitation. A microscopic one-celled parasite. The parasite procreates cysts that are proceeds in the stool of infected persons. The cysts can survive in the environment in water and food and on surfaces and objects. Amebiasis is the third chief parasitic reason of death worldwide, exceed only by malaria and schistosomiasis. On a global basis, amebiasis influences nearly 50 million persons each year, resulting in nearly 100,000 deaths

The mild contour of amebiasis includes nausea, loose stools, weight loss, abdominal tenderness and occasional fever. The symptoms normally are quite mild and can comprise loose stools, stomach pain, and stomach cramping. Amebic dysentery is a harsh form of amebiasis related with stomach pain, bloody stools, and fever. E. histolytica raids the liver and forms an pus. Even less commonly, it spreads to other parts of the body, such as the lungs or brain.

Causes of Amebiasis

Common causes of Amebiasis

• Protozoon( E histolytica)

Symptoms of Amebiasis

Common Symptoms of Amebiasis

• Cramps.
• Nausea.
• Vomiting.
• Loss of appetite.
• Diarrhea.
• Stomach pain.
• Weight loss.
• Abdominal tenderness.

Treatment of Amebiasis

Common Treatment of Amebiasis

• Asymptomatic intestinal infection can be treated with iodoquinol, paromomycin, or diloxanide furoate.
• Recommended drugs in curing symptomatic intestinal disease and for hepatic abscess are metronidazole and tinidazole. Since these drugs can not eradicate the intraluminal cysts, instantly follow this therapy with treatment with iodoquinol, paromomycin, or diloxanide furoate.
• Toxic megacolon may occur and requires total colectomy.
• Surgical decompression may be necessary for amebic brain abscess.
• Rupture of amebic liver abscess into the pericardium may require surgical drainage.
• Conservatively manage intestinal perforation due to amebiasis.
• Drink only bottled or boiled (for 1 minute) water or carbonatized drinks in cans or bottles.

Actinic Keratosis is more habitual to fair-skinned people that are generally exposed to sun, as their pigment is not very preventive. It usually is conducted by solar damage. Since some of these pre-cancers futhers to squamous cell carcinoma. People who made visible their skin to sun normally, mainly without wearing sunscreen, are more probably to ripen actinic keratoses. They are also much general in people having red hair and freckles. AKs used to be more visible in the elderly, they are now seen more often in younger people resulting to changes in the environmental conditions and lifestyles. Actinic keratoses are ingenerated by recurent and prolonged exposure to the sun’s ultraviolet rays. Ultraviolet B (UVB) radiation causes the cells on the surface of the skin to suffer mutations that can cause abnormalities in certain genes. One particular gene which is affected is TP53, a gene that curtail tumors. Actinic keratosis site chiefly ranges between 2 to 6 millimeters, somtimes may be dark or light, tan, pink, red, a combination of all these, or the same pigment of one’s skin.

Patients may mature multiple lesions within a single anatomic area to the extent that the lesions collide and produce confluent AK over a relatively large area. Variants may be broeratosewn (pigmented AK), lichen planus–like, or have exaggerated hyperkeratosis, producing a hornlike projection above the skin surface known as a cutaneous horn. Although rarely seen today, arsenical ks usually occur on patients who were at some time in their live exposed to arsenic, either contained in medication or from an industrial or environmental source. These piles normally on the palms, soles, and inner surfaces of the finger and toes, and then grows and thicken, sometimes increasing in number.

Causes of Actinic Keratosis

Common causes of Actinic Keratosis

• Light complexions.
• Sun exposure( Ultraviolet B)
• Squamous cell carcinoma.
• Abnormalities in certain genes.
• Chemotherapy.
• Chronic leukemia.

Symptoms of Actinic Keratosis

Common Symptoms of Actinic Keratosis

• Dry textured skin lesion.
• Macule or patch and growth on the skin.
• Have a rough texture.
• Itch, burn, or sting.
• Lesions on your skin.

Treatment of Actinic Keratosis

The therapy for actinic keratoses expects upon the number and size of the lesions. An actinic keratosis is generally dealt by liquid-nitrogen cryotherapy. In this therapy, the treatment selectively tears down actinic keratoses, causing little damage to surrounding normal skin, although some lump sometimes occurs. The excision of actinic keratoses is occasionally a useful and definitive treatment in selected lesions. Common Treatment of Actinic Keratosis

• Cryosurgery
• Photodynamic therapy is involves injecting a chemical into the bloodstream.
• Electrocautery is burning off AKs.
• Useful treatment is the application of 5-fluorouracil (5-FU).  The medication is applied on the keratoses for three to six weeks.  5-FU destroys sun-damaged skin cells.
