Reconstruction of skin defects after radical excision of anorectal giant condyloma acuminatum: 6 cases.

The authors report six cases of giant condyloma accuminatum and evaluate the use of mesh-skin grafts in covering the skin defect after radical local excision of perianal giant condyloma acuminatum. Medical records of six patients suffering from the giant condylomata acuminata and treated surgically at the Department of Surgery, Clinical Hospital Center Zagreb, were examined. Use of mesh-skin grafts in covering the skin defect after radical local excision of GCA was compared to other methods of treating the skin defect after radical excision of perianal lesions such as secondary wound healing.

A model of dual circulation in liver acini with hypoxia regulated adenosine secretion.

It was postulated by W.W. Lautt that the hepatic artery flow compensation for changes in portal vein flow (the 'hepatic arterial buffer response') is regulated through the portal blood washout of adenosine from the small fluid compartment that surrounds the hepatic arterial resistance vessels.

Recurrent epistaxis from Kiesselbach area syndrome in patients suffering from hemorrhoids: fact or fiction?

Background: It has been found that >90% of patients suffering from recurrent epistaxis from Kiesselbach area syndrome (REKAS) simultaneously suffered from hemorrhoids. To clarify this, the authors decided to investigate in the opposite direction, i.e.

Successful early pyeloplasty in infants.

Background: Early pyeloplasty for the treatment of congenital ureteropelvic junction obstruction to maximize nephron salvage is justified only if potential hazards of operating on small infants are avoided.

Methods: The records were analyzed of all infants who underwent pyeloplasty over a 5-year period. Open pyeloplasty was performed if collecting systems had deteriorated or were demonstrated to be obstructed; it was also performed for severe cases of hydronephrosis.

The development of blood and lymph vessels of human parathyroid glands in embryonal, fetal and postnatal period.

The aim of the article is to investigate the development of blood and lymph systems in human parathyroid glands in prenatal and postnatal periods. The first capillaries are observed in these glands already in the lunar month 2. At the middle of pregnancy blood supply is increased, being extremely abundant in lunar months 9 and 10, as well as during the first year of life.
