The earliest symptom of Parkinsonism is typically a resting tremor, which often begins in one hand, leg, or chin and progresses over time.

Oral PathologySickle cell anemia has a strong racial predilection, being most prevalent in people of African descent (8-10% carry the sickle trait). This is due to evolutionary selection pressure in malaria-endemic regions where the sickle trait provides protection against malaria. The condition is also found in Mediterranean, Middle Eastern, and Indian populations. Other blood dyscrasias listed do not have such pronounced racial predilections.

Physiology
Pancreatic amylase is an enzyme that plays a key role in the digestion of carbohydrates. It is secreted into the duodenum in response to food and breaks down complex starches into simpler disaccharides like maltose and isomaltose. These disaccharides are then further hydrolyzed by other enzymes into glucose for absorption.

Pharmacology
Carbonic anhydrase is found in erythrocytes, kidney, gut, ciliary body, choroid plexus, and glial cells.
Carbonic anhydrase inhibitors are used primarily as probes for studying renal transport mechanisms and in the treatment of glaucoma
When used to treat glaucoma, carbonic anhydrase inhibitors diminish the transport of HCO3 - and Na+ by the ciliary process, which limits intraocular pressure.
This reduces the formation of aqueous humor by up to 50%, thereby reducing the intraocular pressure. These agents can also limit CSF and endolymph formation.
