From Binet's work the IQ scale called the Binet Scale, (and later the Simon-Binet Scale) was developed. Sometime later, intelligence quotient, or IQ, entered our vocabulary.
Tuberculosis (TB) is an infectious disease that usually attacks the lungs, but can attack almost any part of the body. Tuberculosis is spread from person to person through the air. When a person with TB in their lungs or throat coughs, laughs, sneezes, sings, or even talks, the germs that cause TB may spread through the air.
Overview of the Pathogenesis of Tuberculosis. When tubercle bacilli are inhaled into the lung, the bacilli are deposited in the airways and alveoli in. more ventilated areas of the lungâtypically in the middle to lower regions. The initial inflammatory. reaction in the lung is referred to as a primary or Ghon focus. During this early stage of infection, organisms can spread via lymphatics to the draining lymph nodes. in the chest and result in enlargement of hilar and mediastinal lymph nodes.
