Is the timing of post-vasectomy seminal analysis important?
The complete disappearance of spermatozoa after vasectomy takes longer than is generally believed and we therefore suggest that given adequate counselling, seminal analysis 6 months after vasectomy is cost-effective and in the patient's interest.
Prematurity seems to be the common denominator of the occurrence of NEC. Treatment of NEC in highly immature neonates with birth weight below 1,500g requires comprehensive cooperation of a neonatologist and a children's surgeon. Resection of a necrotic intestine with creation of a stomy remains a standard procedure, which is followed in unstable neonates with a localised form of the illness. Prevention of premature birth, antenatal steroids, frequent feeding (trophic feeding) and the corresponding correction of water management seem to be a reasonable strategy to reduce the incidence of NEC. The resulting incidence, mortality, the time of the occurrence of NEC and the therapeutic procedures are within the limits stated in the international literature.
