Human health and medicine

Fungal pneumonia

Fungal pneumonia is lung inflammation caused by a fungus rather than bacteria or viruses, most often affecting people with weakened immune systems and treated with antifungal medicines.

Furaprevir (TG-2349) is an investigational HCV NS3/4A protease inhibitor developed by TaiGen and Dongguan HEC TaiGen for chronic hepatitis C; it reached Phase 3 combination trials with yimitasvir but was never approved and development was abandoned in 2023.

Furosemide

Furosemide, also known as frusemide and sold as Lasix, is a loop diuretic introduced in 1962 and used to treat edema from heart failure, cirrhosis, and kidney disease.

Furuncular myiasis

Furuncular myiasis, also called botfly or tumbu fly myiasis, is a boil-like cutaneous infestation by fly larvae, mainly Dermatobia hominis in the Americas and Cordylobia anthropophaga in Africa, treated by occlusion, ivermectin, and larval extraction.

Fusafungine

Fusafungine (Bioparox, Locabiotal) is a fungal enniatin peptide antibiotic and anti-inflammatory nasal/oromucosal spray from Fusarium lateritium, authorised in Europe in 1963 and withdrawn in 2016 over serious allergic reactions and weak efficacy evidence.

Fusariosis

Fusariosis (Fusarium infection) is disease caused by Fusarium molds from soil and water, causing keratitis, onychomycosis, and, in immunocompromised patients, disseminated infection with fever, skin lesions, and positive blood cultures.

Fused fingers

Fused fingers, or syndactyly, is a congenital fusion of adjacent digits, simple (soft tissue) or complex (bony, ICD-11 LB79.0). Occurs in about 1 in 2,000 births; surgery between 18 and 24 months separates digits with flaps and grafts.

Fused mandibular incisors

Fused mandibular incisors (ORPHA:2287, OMIM 147251) is an extremely rare dental anomaly in which two normally separated lower incisor tooth germs of the primary dentition unite, often with hypodontia and pulp exposure risk; distinguished from gemination by tooth count.

Fused pelvic kidney

Fused pelvic kidney, also called pancake or cake kidney (ICD-11 LB30.61), is a rare complete renal fusion anomaly: both kidneys fuse into one pelvic mass drained by two ureters that do not cross the midline, unlike crossed fused ectopia.

Fusidic acid

Fusidic acid (Fucidin) is a steroid-structured antibiotic produced by a fungus, discovered in 1960 at LEO Pharma in Denmark and used chiefly against staphylococcal skin infections.

Fusion imaging

Fusion imaging is a medical imaging technique that overlays real-time ultrasound with previously acquired CT, MRI, or PET/CT, guiding biopsies and tumor ablations without radiation.

Fusion of labia

Fusion of labia, also known as labial fusion or labial adhesion, is a condition where the labia minora stick together, mainly affecting prepubertal girls with low estrogen.

Fusion prostate biopsy

Fusion prostate biopsy is a targeted technique that registers pre-procedure prostate MRI with real-time ultrasound so urologists can aim needles at MRI-visible suspicious lesions, one of three common MRI-targeted biopsy techniques.

Futibatinib

Futibatinib (Lytgobi, TAS-120) is an oral, irreversible covalent FGFR1–4 inhibitor approved in 2022 for previously treated FGFR2-rearranged intrahepatic cholangiocarcinoma; FOENIX-CCA2 showed 42% response rate.

FUTURE II trial

FUTURE II (NCT00092534, V501-015) is Merck's phase 3 trial of the quadrivalent HPV-6/11/16/18 vaccine in 12,167 women aged 15–26; 98% per-protocol efficacy against HPV16/18-related CIN2/3 or AIS, 100% effectiveness over 14 years. A separate coronary scaffold trial shares the name.

Futuximab

Futuximab (mAb992), with modotuximab (mAb1024), forms Sym004, a 1:1 mixture of chimeric IgG1 anti-EGFR antibodies binding non-overlapping EGFR domain III epitopes, inducing EGFR internalization and degradation; investigated in colorectal, head and neck, esophageal cancers and glioblastoma.

Fuzi Decoction

附子汤 (Fuzi Decoction), a classical formula from Zhang Zhongjing's Shanghan Lun: processed aconite, poria, ginseng, atractylodes, and peony, warming yang and dispelling cold-damp for shaoyin disease with back aversion to cold and joint pain; distinct from Zhenwu Decoction by one herb.

G-spot

G-spot (Gräfenberg spot): a putative erogenous area on the anterior vaginal wall, named after Ernst Gräfenberg. Systematic reviews find no agreed anatomical structure; existence, location, and nature remain unproved.

G. Edward Griffin

G. Edward Griffin, born George Edward Griffin in 1931, is an American author and filmmaker known for The Creature from Jekyll Island and conspiracy-oriented books.

G. Gayle Stephens M.D.

G. Gayle Stephens (1928 to 2014) was an American family physician and medical educator who was one of the founders of family medicine in the United States.

G. Octo Barnett

G. Octo Barnett, born Guy Octo Barnett, was an American physician and medical informatics pioneer who founded the Massachusetts General Hospital Laboratory of Computer Science.

GA-10

GA-10, also written GA10, is a human Burkitt lymphoma cell line established in 1996 from the blood of a male patient whose lymphoma resisted CHOP chemotherapy.

GABAergic interneuron

GABAergic interneuron: local inhibitory neuron using GABA as neurotransmitter, also called GABAergic inhibitory interneuron. Three cortical groups (PV ~40%, SST ~30%, 5HT3aR ~30%) arise from the ganglionic eminence and regulate circuit timing.

Gabapentin

Gabapentin (Neurontin), a gabapentinoid GABA analog, binds the alpha2delta-1 calcium channel subunit; FDA-approved 1993 for partial seizures and 2002 for postherpetic neuralgia, widely prescribed off-label for neuropathic pain, with known misuse and overdose risks.

Gabapentin enacarbil

Gabapentin enacarbil (Horizant, Regnite, XP13512) is an extended-release prodrug of gabapentin approved for moderate-to-severe primary restless legs syndrome and postherpetic neuralgia, dosed 600 mg daily for RLS, with somnolence and dizziness as common adverse effects.

Gabexate

Gabexate (gabexate mesilate, FOY), a synthetic serine protease inhibitor with a minutes-long half-life, used in Japan and Italy for acute pancreatitis, DIC, and post-ERCP pancreatitis prophylaxis, with mixed trial evidence.

Gaboxadol

Gaboxadol (THIP), an extrasynaptic GABAA receptor agonist developed by Lundbeck and Merck for insomnia; development stopped in 2007 over variable efficacy and psychiatric side effects; later orphan-designated for Angelman syndrome and Fragile X.

GABRB3

GABRB3, also called ECA5/DEE43, is a human gene at 15q12 encoding the beta3 subunit of the GABA_A inhibitory chloride-channel receptor. Pathogenic variants split into gain- and loss-of-function groups causing distinct epileptic encephalopathies; reduced expression marks Angelman and Prader-Willi syndromes.
