#386. Name the medical term : An abnormally low number of neutrophils. Neutrophils usually make up 60 to 70% of circulating white blood cells and serve as the primary defense against infections by destroying bacteria in the blood. Hence, patients with this disease are more susceptible to bacterial infections and, without prompt medical attention, the condition may become life-threatening and deadly (neutropenic sepsis).

#384. Name the medical term : Position of a baby in the uterus such that the head of the baby is presenting first and is tilted to the shoulder, causing the fetal head to no longer be in line with the birth canal. It is significantly different from a shoulder presentation, in which the shoulder is presenting first. Many babies enter the pelvis in this presentation, and most of it corrects spontaneously as part of the normal birthing process. Persistence of this can cause problems with dystocia, and has often been associated with cesarean birth.
