pharyngodynia	pharyngalgia	Nidara­t
Pharynx And Intestinal Excess	PIE
phase I trial	The first step in testing an experimental drug in humans. Phase I trials evaluate the drug's safety and toxicity at different dose levels and determine drug pharmacokinetics. Because little is known about the possible risks and benefits of the drug being tested, Phase I trials usually include only a small number of participants (20 to 80) Testing of other biomedical interventions, such as diagnostic tests or medical devices, also begins with Phase I trials.
phase II trial	The second step in testing an experimental drug (or other treatment) in humans. Typically, Phase II trials are done only if Phase I trials have shown that the drug is safe, but sometimes Phase I and Phase II trials are combined. Phase II trials are designed to evaluate the drug's effectiveness in people with the disease or condition being studied and to determine the common short-term adverse effects and risks associated with the drug. Phase II trials involve more participants (often several hundred) and typically last longer than Phase I trials.
phase III trial	The third step in testing an experimental drug (or other treatment) in humans. Phase III trials are conducted to confirm and expand on safety and effectiveness results from Phase I and II trials, to compare the drug to standard therapies for the disease or condition being studied, and to evaluate the overall risks and benefits of the drug. This trial phase recruits a large group of people with the disease or condition, usually ranging from 1,000 to 3,000 participants. Results from Phase III trials provide information that the Food and Drug Administration (FDA) needs to consider the drug for approval.
phase IV trial	Testing in humans that occurs after a drug (or other treatment) has already been approved by the Food and Drug Administration (FDA) and is being marketed for sale. Phase IV trials are conducted to determine long-term safety and effectiveness and to identify adverse effects that may not have been apparent in prior trials. Thousands of participants are usually recruited to volunteer for this phase of clinical testing.
PHC	protein histocompatibility complex
phenotypic antiretroviral resistance test	A type of resistance test that measures the extent to which a person's strain of HIV will multiply in different concentrations of antiretroviral (ARV) drugs. Resistance testing is used to guide selection of an HIV regimen when initiating or changing antiretroviral therapy (ART)
phenotypic assay	A type of resistance test that measures the extent to which a person's strain of HIV will multiply in different concentrations of antiretroviral (ARV) drugs. Resistance testing is used to guide selection of an HIV regimen when initiating or changing antiretroviral therapy (ART)
phf	per high powered field	V.Sok
Philadelphia County Medical Society	PCMS
Phoenix Memorial Hospital	PMH
phoniatrist	фониатр	Анаста­сия Бел­яева
phonopaedist	фонопед	Анаста­сия Бел­яева
phos	phosphorus	Vosoni
phosphonoformate	foscarnet
photosensitivity	Abnormal sensitivity to light. Symptoms may include reddening and blistering of the skin. Use of some antiretroviral (ARV) drugs may cause photosensitivity reactions.
phrenesis	phrenitis	Andrey­ Truhac­hev
phrenitis	encephalitis	Andrey­ Truhac­hev
phrenitis	delirium	Andrey­ Truhac­hev
