Understanding, Diagnosing, and Using Genetic Testing for Carcinoma of Male Breast
Lumps, nipple discharge and skin dimpling can signal breast cancer in men; BRCA1 and BRCA2 testing informs screening, treatment choices and risk for relatives.
Understanding, Diagnosing, and Using Genetic Testing for Cerebral Arteriovenous Malformation
Tangled arteries and veins in the brain can bleed or cause seizures; MRI, CT and cerebral angiography locate them, while genetic testing may show familial risk.
Understanding, Diagnosing, and Using Genetic Testing for Cerebral Edema
Swelling of the brain can follow head injury, stroke, infection, tumors or high altitude; CT and MRI show its extent, and testing can reveal inherited predispositions.
Cerebral Palsy: Symptoms, Diagnosis and Exome Testing
Damage to the developing brain affects movement, muscle tone and posture; exome sequencing can identify genetic causes of cerebral palsy to guide care.
Cholesteatoma: Ear Growth, Hearing Loss and Diagnosis
An abnormal, non-cancerous growth of skin cells behind the eardrum, cholesteatoma can erode middle-ear bones; otoscopy, CT scans and hearing tests find it.
Cholesteatoma of the Middle Ear: Vertigo and Imaging
Persistent ear discharge, hearing loss and vertigo point to this growth behind the eardrum, where vertigo may signal labyrinthine fistula; CT and MRI help.
Understanding, Diagnosing, and Using Genetic Testing for Chronic Sinusitis
Sinus inflammation lasting more than 12 weeks brings congestion, facial pain and reduced smell; imaging, nasal endoscopy and gene testing are covered.
