Hyperparathyroidism and Hypoparathyroidism
Hyperparathyroidism and Hypoparathyroidism The parathyroid glands are critical regulators of calcium, phosphate, and bone metabolism. Pathologies affecting these glands typically manifest as disorders of calcium homeostasis, presenting either as hypercalcemia (hyperparathyroidism) or hypocalcemia (hypoparathyroidism). 1. ANATOMY AND PHYSIOLOGY OF PARATHYROID GLANDS Embryology and Anatomy Definition: Small endocrine glands located in the neck, usually situated behind…

Oxygen Administration
INHALATION Inhalation is the breathing of air vapor or volatile medicine into the lungs. Types Dry inhalation: Oxygen Administration: this is given when the respiratory capacity is diminished as in chest injuries, pneumonia and cardiac failure. Moist/steam inhalation: It is used in case of inflammation of air passages and the nasal sinuses. These are given…

Endemic Dimorphic Fungi
Endemic Dimorphic Fungi I. Introduction: What are Dimorphic Fungi? Certain highly pathogenic fungi exhibit Thermal Dimorphism, meaning a single fungal species can demonstrate two entirely different structural forms depending strictly on the temperature of their environment. The Two Forms: Mycelial (Mold) Form: Occurs in the free-living form in nature. Grown in the laboratory at 30°C…
