Yes. A hormonal imbalance can cause spotting, and it does so through a specific mechanism: hormones control the growth and maintenance of the uterine lining (endometrium), so when estrogen, progesterone, or related signaling falls out of…
Read the story ↗Yes, a dilated pancreatic duct can be normal. The main pancreatic duct normally measures up to about 3 mm in the head, 2 mm in the body, and 1 mm in the tail, and it widens modestly with age, so a measurement of 3 to 4 mm in an older adult…
Contact dermatitis blisters form when allergens or irritants breach the skin barrier and trigger an inflammatory cascade that separates the epidermis from the dermis, filling the gap with plasma-derived fluid.
No, adults do not have growth plates. The epiphyseal plates that lengthen bones fuse completely during adolescence and early adulthood, typically between ages 13 and 20 depending on sex and bone, replacing cartilage with solid bone.
Yes, you can wear a bulletproof vest, and in most US states any legal adult can buy and wear one without a permit.
Yes, an MRI can make you dizzy or trigger vertigo, but the cause is almost never the magnetic field itself.
Crackling when you exhale is usually the sound of airways snapping open or closed as trapped air and secretions move through them, not the sound of tissue tearing or "fluid in the lungs" in the way most people picture it.
Yes, an enlarged prostate can raise PSA, but benign enlargement typically lifts PSA modestly, roughly in proportion to gland volume, and it does not produce the steep or accelerating rises that cancer does.
No, kidneys cannot repair themselves once dialysis becomes permanent, but partially damaged kidneys can recover enough to stop dialysis in specific, time-limited situations. Dialysis replaces filtration but does not heal kidney tissue.
Can an inhaler kill you? Yes, in rare circumstances an inhaler can contribute to death, but the risk is very low and heavily dependent on the drug, the dose, and the underlying condition.
Yes, most people with a pacemaker can keep working, and many return to the same job within days to weeks of implantation.
No, current evidence does not show that COVID-19 vaccines cause multiple sclerosis. Large population studies and safety monitoring systems have found no increased risk of new-onset MS after vaccination.
Contemporary nursing practice is a regulated, evidence-based clinical discipline in which licensed nurses use structured assessment, continuous monitoring, and interprofessional coordination to detect patient deterioration early, prevent…
Diltiazem is not a controlled substance under U.S. federal law. It is a Schedule-exempt prescription calcium channel blocker, not listed in any of the five schedules of the Controlled Substances Act (21 U.S.C. § 812).
Carbon dioxide affects humans and the environment because it is not merely an inert byproduct: it drives acid-base chemistry in the blood, traps outgoing infrared radiation in the atmosphere, acidifies seawater, and fertilizes plant growth…
No, a standard drug test cannot directly tell whether a urine sample is old. Immunoassay and mass spectrometry screens detect drug compounds and their metabolites, not the age of the specimen.
Yes, a vibrator can make you pee, but not because vibration targets the bladder directly.
Cauliflower flowering is not a single event but a two-stage transition: the plant first builds a dense, edible "curd" of arrested flower buds during vegetative growth, then a cold period triggers those buds to elongate into a branched…
Yes. A traumatic brain injury can cause tinnitus, and the link is strongest for blast exposure and injuries involving the head, neck, or temporomandibular joint.
Convergent boundaries destroy lithosphere where plates collide, producing subduction zones, mountain belts, and the planet's largest earthquakes.
The cervix before a period is typically firm, higher in the vaginal canal, and closed, with scant thick or creamy discharge.
If you are asking yourself "Did I experience childhood trauma?", the honest answer is that you may have, even if your childhood looked normal from the outside. Childhood trauma is not limited to abuse or violence.
Yes: a sinus infection can produce a positive COVID test, but only if SARS-CoV-2 is actually present. A bacterial sinus infection cannot turn a COVID test positive.
The Crescent and Avalon dual-lumen ECMO cannulas differ mainly in how they manage drainage and reinfusion within a single vessel: the Avalon relies on a fixed, self-expanding polymethylpentene membrane and preset port geometry, while the…
