Abstract:
Abstract Anomalies of the fetal umbilical vessels are rare, excepting single umbilical arteries which occur in 0.2–1.0% of pregnancies1. Abnormalities of the intra‐abdominal umbilical vein may be categorized into three main groups: (1) the ductus venosus is patent but the right umbilical vein persists; (2) the ductus venosus is not patent, and there is extrahepatic continuation of the umbilical vein; and (3) the umbilical vein takes a normal course but is abnormally dilated. We describe cases of each of these types of anomaly, including the first report of prenatal diagnosis of insertion of the umbilical vein into the iliac vein, and review the literature on this subject.

The umbilicus is the remnant of the connection between the foetus and the dam. During the first few days of life, the umbilicus is the major portal of entry of micro-organisms into the neonate. Contamination of the umbilicus and failure of passive transfer of immunoglobulins are the factors most likely responsible for the development of umbilical infections. Infection can be limited to the extra-abdominal umbilicus or can include the liver or bladder following spread of the infection via the umbilical remnants into the abdominal cavity. Infection of the extra-abdominal umbilicus can be treated conservatively with local disinfectants and parenteral antimicrobial treatment, but hernias and infections of the umbilical remnants should be treated surgically.

Abstract Omphalophlebitis, generally referred to as navel ill, is a common post-mortem meat inspection finding in very young calves slaughtered in New Zealand, and a gross pathological, histopatho-logical and bacteriological evaluation of 147 carcasses condemned for this condition at routine post-mortem meat inspection was undertaken. Localised lesions restricted to the umbilicus alone were present in 29.9% of cases. The majority of cases included gross pathological change in the umbilical vessels and other tissue sites beyond the umbilicus. Most hepatic nodes were grossly normal but histological examination revealed that 61.5% of nodes from other than localised cases of navel ill were hyperplastic. However, there was little difference in the prevalence of hyperplastic hepatic nodes from cases of localised navel ill (21.4%) compared with normal calves (15.9%). Despite the wide range of bacteria isolated from umbilical lesions, Salmonella typhimurium recovered from the navel, liver and hepatic nodes of a single "extended" case of navel ill was the only isolation of known public health importance. Given the separation of cases of navel ill into different gross pathological, histopathological and microbiological categories, current meat inspection judgments whereby all calves with navel ill are condemned should be revised. In particular, routine condemnation of the carcass and viscera in all cases of localised navel ill (lesions restricted to the umbilicus alone) should be reassessed.

To explore the umbilical vein branches of the fetal and the quantity of blood passing through the liver and the ductus venosus. Method Sixty two normal fetal livers were chosen after being fixed with formalin. The branches of umbilical vein were anatomized, observed and measured.Results There was a significant difference of the total cross section area between the umbilical vein branches pass through the liver and the ductus venosus (P0. 001). The sectional area passing through the liver conclusion was larger than that of ductus venosus.Conclusion In the fetal, the great majority of umbilical blood passes through the liver to in ferior vena cava and only small part flows into the ductus venosus. There is over two - thirds umbilical vein blood passing through the 1iver to left lobe.

A field study, controlled at the farm level, was conducted utilizing 495 newborn calves in 13 commercial Wisconson dairy herds to evaluate the use of a new umbilical disinfectant dip (Navel Guard (NG), Sirius Chemical Group, McDonough, GA) to prevent umbilical infections (omphalitis) as compared to 1) not dipping the umbilicus at birth, 2) dipping the umbilicus with 7% tincture of iodine, or 3) dipping the umbilicus with solutions containing a lower concentration (0.5 to 2%) of iodine.

Introduction: The umbilical scar is the only scar that is culturally accepted and whose dysmorphia or absence catches people's attention. Studies have discussed numerous umbilicus reconstruction techniques but not any for repositioning the umbilicus during or after liposuction. In this study, we will introduce a technique called “umbilicosliding” that is used to prevent or correct a defect known as the “sad umbilicus” without visible scarring. Method: A retrospective study was conducted from 2010 to 2014 in which 32 patients fulfilled the inclusion criteria. Preoperative and postoperative photographs were analyzed by two plastic surgeons that were not on the team at the time of the procedures. Patients were recalled and surveyed about results. Results: The external assessment of aesthetic outcome by photographic results were 31% (n = 10) excellent, 47% (n = 15) good, 22% (n = 7) regular, and 0% bad. Recalled patients assessed the aesthetic outcome at 25% (n = 8) excellent, 66% (n = 21) good, 9% (n — 3) regular, and 0% bad.

Umbilical lesions constitute a comparatively lesser percentage of the specimens received on a daily basis for histopathological examination. During embryological development, the umbilicus functions as a channel that allows flow of blood between the placenta and fetus. It also serves an important role in the development of the intestine and the urinary system. After birth, once the umbilical cord falls off, no evidence of these connections should be present. Nevertheless a few lesions are encountered related to the same. Patients with umbilical disorders present with drainage, a mass, or both. Umbilical granuloma, omphalomesenteric remnants, urachal remnants, hernias are few lesions in the umbilical region. We present a case of an umbilical polyp in an infant, which clinically suspected to an umbilical granuloma. The idea behind presenting this case was that, not only are umbilical polyps rare lesions but also it is necessary to differentiate it from umbilical granuloma as the treatments may vary. The clinicians and reporting pathologists must be aware of this rare congenital lesion.
