Twin to twin transfusion syndrome
MONDO:0019805Twin twin transfusion syndrome (TTTS) is a rare condition seen in twin monochorionic pregnancies, typically developing during the 15-26 week gestation period and usually due to unbalanced intertwin placental anastomoses, where an unequal exchange of blood between twins causes oligohydramnios in one sac and polyhydramnios in the other which can lead to a high perinatal mortality rate and a high rate of disability in survivors if left untreated
Also known as: Feto-fetal transfusion syndrome, Twin Anemia Polycythemia Sequence, Twin-Twin transfusion syndrome, foetal blood loss from foetal haemorrhage into co-twin, foetal haemorrhage into co-twin, placental transfusion syndrome, stuck Twin syndrome, twin-to-twin transfusion syndrome

Could a painless light sensor replace the needle for anemia screening?
Diagnosis Not yet recruitingThis study tests whether a non-invasive device that uses light to measure hemoglobin through the skin can accurately detect anemia. Researchers will compare its readings with standard blood tests in 150 adults in Jakarta. If the device proves reliable, it could offer a quick, pai…

Zapping pain without drugs: brain stimulation put to the test for nerve pain
Symptom relief Not yet recruitingThis trial tests whether a non-invasive brain stimulation technique called temporal interference stimulation (tTIS) can reduce neuropathic pain—pain caused by nerve damage. Researchers will monitor changes in pain levels and brain plasticity in 60 adults with peripheral neuropath…
