Cough is a protective reflex, its purpose being expulsion of respiratory secretions or foreign particles from air passages. It occurs due to stimulation of mechano- or chemo- receptors in throat, respiratory passages or stretch receptors in the lungs. Cough may be useful or useless. Useless (unproductive) cough should be suppressed. Useful (productive) cough serves to drain the airway. Its suppression is not desirable, it may even be harmful, except if the amount of expectoration achieved is small compared to the effort of continuous coughing.

CHICKEN-POX
Chicken-pox is a very contagious disease of children. The disease occurs in epidemics, especially in children under the age
of ten years. Children of-the first four years of life are the most susceptible. There is an incubation period of 1421 days, most frequently 17 days.
The first symptoms are the following: a slight fever and sometimes pains in the back and legs. Almost at the same time (within twenty four hours) a characteristic eruption appears on different parts of the body. It is found very frequently on the scalp (the hairy part of the head).
The eruption consists of red macules quickly progressing to papules and vesicles. Soon they become crusted. The brownish crusts dry up and fall off in two three weeks. The child remains infectious until the scabs scale.
The number of vesicles is very variable. In a slight case there may only be eight or ten of the vesicles, but sometimes in severe cases their number may amount to six or seven hundred.
In the vast majority of cases there is no difficulty in making a diagnosis, but a doctor must learn how to differentiate it from other skin disorders especially from smallpox.
Chicken-pox is one of the mildest of acute infectious diseases of children. Children remain feverish for 2 3 days, while new vesicles still appear and after that feel well.The recovery is usually complete. Complications are rare. Encephalitis may occur in uncommonly severe cases..
In the majority of cases no other treatment beyond isolation is required. The child should be kept in bed during the eruptive stage and as long as there is any fever. The lesions should be treated with a disinfective solution.

SCARLET FEVER
Scarlet fever is an acute contagious disease characterized by high temperature, rapid pulse, a punctate eruption 'followed by desquamation, inflammation of the throat. It is caused by Hemolitic Streptococcus.
The disease may be transmitted either by various objects clothing, toys, books and food-stuffs, infected by the patient or by means of droplet infection (during coughing, sneezing or talking).
All children are susceptible, particularly frequently between 18 months and 10 years of age. Adults also contract this illness, but they have only sore throat without the eruption characteristic of scarlet fever.
The incubation period of the disease lasts on an average 47 days; sometimes it only jtakes a few hours.
The onset of the disease is sudden. There is generally a very sore throat, a sharp rise of temperature to 39 40C, nausea, vomiting, headache and often chills. The lymphatic nodes of the neck are enlarged. The child' is restless and sleeps badly.
Within a few hours, but more often at the end of the first or in the beginning of the second day a diffuse red rash appears on the neck, chest and back, spreading to the arms and legs. The area around the mouth remains free from rash. The rash lasts one or three days and then fades away. After the disappearance of the rash the period of desquamation begins. Desquamation continues 1014 days.
If no complications develop and patients feel good they are allowed out of the bed after the 7th day of the disease. They may be discharged from the hospital on the 1214th days.
The principal complications are acute nephritis, adenitis, otitis media, pericarditis, endocarditis, etc.
Scarlet fever patients should be isolated and stay in bed. Careful disinfection of the patient's things is important. Antibiotics are prescribed.
