Symptoms.--It usually affects first the mucous membrane of one cheek, near the corner of the mouth, as a dark, ragged, sloughing ulcer and spreads for two or three days before the substance of the cheek is infected. If you grasp the cheek between the thumb and finger you can then feel a hard and sensitive lump. The cheek may be eaten through by the third day, though a week generally passes before this happens. There is a burning watery discharge from the unhealthy wound. The breath smells terribly and it is almost unbearable. The gangrene may spread over one half of the face of the side affected. TREATMENT.--The death rate is eighty to ninety per cent. This is a very dangerous disease and a doctor must be in attendance. Cut, away all the dead tissue by using burning caustics, such as fuming nitric acid, solid zinc chloride, nitrate of silver, carbolic acid on the actual canker. Sometimes mild applications like sub nitrate of bismuth, chloride of potash or the following do well:-- Sulphate of copper 2 drams Powdered cinchona 1/2 ounce Water enough to make 4 ounces Mix and apply. Peroxide of hydrogen is good as a disinfectant or boric acid solution, etc., may be used. Keep up the patient's strength. Fortunately this disease is rare. I have never seen a case in practice. Salivation.--Stop the mercury, keep the bowels open and use the same antiseptic washes as directed for sore mouth. [100 MOTHERS' REMEDIES] Chlorate of Potash Solution, Soda Solutions, Boracic Acid Solutions.--Brush the ulcers with nitrate of silver sticks. Keep the mouth clean with hot water washes and some of the antiseptics put in the water as boric acid, soda, glycothymotine, listerine, etc. ACUTE DYSPEPSIA.--(Acute Indigestion, Acute Gastritis). "Gaster" is the Greek for stomach; "itis" means inflammation,--thus acute inflammation of the stomach. It may be acute or chronic. When acute it may be called acute gastritis, acute gastric catarrh, acute dyspepsia or acute indigestion. When chronic it may be called chronic gastritis, chronic catarrh of the stomach, chronic dyspepsia or chronic indigestion. Causes.--This is a very common complaint and is usually caused by eating foods that are hard to digest, which either themselves irritate the stomach, or remain undigested, decompose, and so excite an acute dyspepsia, or indigestion, or it may be caused by eating or taking in more than the stomach can digest. A frequent cause is eating decomposing food, particularly in hot weather. Alcohol is another great cause. Symptoms.--In mild cases. Distress in the stomach, headache, weary feeling, thirst, nausea, belching of wind, sour food, and vomiting; the tongue is heavily coated and the saliva increased. In children there are loose bowels and colicky pains. It lasts rarely more than twenty-four hours. Vomiting usually relieves the patient.
