Unfortunately, within the framework of one answer to such a voluminous request, I can only give a brief, superficial description of the disease.
**Omphalitis** is inflammation of the umbilical wound, usually occurring 22 - 28 days after birth. For premature babies, this period is approximately one to two weeks. The development of omphalitis is based on infection of the remnants of the umbilical vessels. The causative agents of infection are cocci and diplococci, Escherichia coli, Proteus, and less commonly Mycobacterium tuberculosis. Less commonly, the development of o. caused by another infection, for example staphylococcal, fungal, diphtheria,
Omphalitis can be purulent and septic. When purulent, the wound can fester either with or without pressure. The testicle protrudes beyond the edge of the tunica albuginea by 3–4 mm. The swelling of the scrotum can be easily felt. The skin and subcutaneous tissue over the testicle are smoothed, redness and infiltration are possible. Rarely, an abscess may form on the scrotum.
