anesthesia in ob, interruption of oxytocin release in response to cervical dilatation may cause uterine inhibition

FIFTH DISEASE
erythema infectiosum, associated with parvovirus B19 infection, characterized by "slapped cheeks" and erythematous lacy eruption on the trunk and extremities; other 4 childhood rash diseases: measles, rubella, scarlet fever, and roseola (herpesvirus VI)

FLATBUSH DIABETES
GAD antibody negative NIDDM in adult black subjects with diabetic ketoacidosis and increased frequency of human leukocyte antigen DR3 and DR4
FOIX-ALAJOUANINE DISEASE
angiodysgenetic necrotizing myelopathy, venous angiomatous malformation of the spinal cord and overlying meninges associated with ischemia and worsening neurologic symptoms in lumbosacral cord
FORDYCE'S SPOTS
ectopic sebaceous glands seen in healthy mouth; may be confused with Koplik's spots which has an erythematous halo by comparison
FORRESTER CLASSIFICATION
in myocardial infarction, I, PWP2.2 L/min/m2, 2% mort; II, PWP>18 and CI>2.2, 10% mort; III, CI18 and CI<2.2, 54% mort
FORSCHEIMER SPOTS
in rubella, punctate soft palate macules
FOSTER KENNEDY SYNDROME
optic atrophy, contralateral papilledema, and anosmia; may be associated with olfactory groove meningioma
FOTHERGILL'S SIGN
in rectus sheath hematomas, tender mass that does not cross the midline and remains palpable when patient tenses the rectus muscle (bluish discoloration not usually seen until 3 or 4 days)
FOURNIER'S GANGRENE
necrotizing infection of the perineal and genital fascia
FOUVILLE'S SYNDROME
dorsal pontine injury giving rise to lateral gaze palsy, ipsilateral facial palsy, contralateral hemiparesis
FOX'S SIGN
in hemorrhagic pancreatitis, ecchymosis of the inguinal ligament due to blood tracking from the retroperitoneum and collecting at the inguinal ligament
FRANK'S SIGN
earlobe crease, associated with CAD (N Engl J Med. 1973;289:327-8)
FRANKLIN'S DISEASE
gamma heavy chain disease, characterized by LAD, fever, anemia, malaise, HSM, and weakness, most distinctive symptom palatal edema
FREY SYNDROME
gustatory sweating or auriculotemporal syndrome seen in the context of parotid surgery; ipsilateral forehead becoming drenched with sweat apparently because of some salivery nerve fibers connecting with autonomic efferents
FRIEDREICH'S ATAXIA
a spinocerebellar degeneration, AR manifesting at 11 years, a less common AD 20 years; initial symptoms, gait ataxia, hand clumsiness, dysarthria, DTRs absent (extensor plantar present), joint position and vibratory sense impaired, sometimes loss of pain and temperature, paralyzed over course of 20 years, high incidence of diabetes and hypertrophic cardiomyopathy (dilated less common) and arrhythmias
FRIEDREICH'S FOOT
seen in Friedreich's ataxia, pes cavus with hammer toe
FRIEDREICH'S SIGN
exaggerated y descent in patients with increased venous pressure, associated with an S3; also associated with constrictive pericarditis
FROMENT'S SIGN
diagnosis of ulnar nerve lesion; caused by flexor pollicus longus (median nerve) which comes into action when the patient attempts to grip a flat object between the thumb and the hand, and causes flexion at the interphalangeal joint
