呼吸系统(英文版) PPT-

The nasopharynx is the fist division, and it is nearest to the nasal cavities. It contains the adenoids, which are masses of lymphatic tissue. The adenoids (also known as the pharyngeal tonsils) are more prominent in children, and if enlarged, they can obstruct air passageways.

Case -1
Jack, age four months, is sent at home by his general practitioner because of two days of rapid, laboured breathing and poor feeding. He was born at 27 weeks’ gestation, birth weight 979g and was discharged home at three months of age. On examination he was a fever of 37.4C and a respiratory rate of 60 breaths/min. His chest is hyperinflated with marked intercoatal recession. On auscultation there are generalized fine crackles and wheezes.

Etiology and pathogenesis
Silica particles less than 5 μm in diameter enter lungs and are phagocytozed by macrophages.
Free particles and fibroblast stimulating factor are released from the dead macrophages.
Basic PATHOLOGY
Today’s contents
Pneumoconiosis: Silicosis Chronic cor pulmonale Pulmonary carcinoma
Pneumoconiosis
a term originally coined to describe the lung reaction to inhalation of mineral dusts and now has been broadened to include diseases induced by:
Crystalline is the most toxic and fibrogenic, especially quartz.
Ingested silica particles
activation of pulmonary macrophage
release of mediators by pulmonary macrophage: IL1, TNF, Fibronectin Lipid mediators Oxygen-derived free radicals Fibrogenic cytokines
Stage Ⅲ:
Lesion may occur at entire lung with progressive massive fibrosis with cavities. There is grating when cut . The merged silicotic nodules are enlarged in size and demonstrate a neoplasm-like mass.
Morphology
1. Formation of silicotic nodules. 2. Diffuse fibrosis of pulmonary stroma.
ቤተ መጻሕፍቲ ባይዱ
The nodules are black or gray-white in color and physically hard, tiny barely palpable, discrete ones in upper zones of the lungs.
Silicosis
Conception:
Silicosis is one of pneumoconiosis caused by deposition of silica particles in lungs. The characteristic lesion is silicotic nodule consisted of concentrated collagen fibers.
grating when cut.
In an advanced case, the lungs may be almost completely solid.
The hilar lymph nodes are much enlarged and pleura also involved even in the early stages, and their cut surface resembles the nodules.
The merged silicotic nodules are demonstrated
Histologically, the silicotic nodule often experienced three stages:
cellular nodule
fibrotic nodule
hyaline nodule.
Staging
Stage Ⅰ:
Lesion limited at the hilar lymph nodes and subpleural zones with the silicotic nodules is few in number.
Stage Ⅱ:
Lesion may scattered at upper and lower area in lung concentrated in the hilus with the silicotic nodules increase in number.

Microscopically, the silicotic nodule demonstrates concentrically arranged hyalinized collagen fibers surrounding an amorphous center. A “whorled” appearance of the collagen fibers typically.
