Zoonotic ocular onchocercosis caused by Onchocerca lupi in dogs in Romania.

Onchocerca lupi is a filarial nematode, which infects the scleral conjunctival tissue of dogs, wolves and cats. Whilst adult nematodes localize in the conjunctive tissue of sclera or in the retrobulbar, microfilariae are found in the skin, and they are rarely diagnosed in asymptomatic animals. Since the first report of human ocular infection 5 years ago, up to 10 zoonotic cases have been identified in patients worldwide. We report, for the first time in Romania, three cases of canine ocular onchocercosis in dogs. Fragments of the harvested worms were characterized morphologically and molecularly. This article expands knowledge on the distribution of this parasite in Eastern Europe and sounds an alarm bell for ophthalmologists about the possible occurrence of human cases of O. lupi infection.

[Postoperative digestive fistulas. Etiopathogenic considerations]. / Consideratii asupra etiopatogeniei fistulelor digestive externe postoperatorii.

The digestive fistula is one of the most serious complications that might appear following different types of resectional digestive surgery. This condition still carries a considerable morbidity and mortality rate and therefore all surgical and ICU staff pay a great deal of attention and intensify their care to avoid the fatalities. The postoperative digestive fistulas, through their physiopathological and clinical complexity induce the disturbance of the biological equilibrium with vital consequences. The trend of the last decades is the increasing of digestive fistulas incidence with a variable mortality rate after different authors. A therapeutic algorithm is needed. The mortality rate due to digestive fistulas, two decades ago was, around 60%; at the present there is a decrease of the mortality rate, which is around 10%. The explanation is the introduction of the new methods of treatment such as lactic acid lavage aspiration for alkaline fistulas or total parenteral nutrition, continuous enteral nutrition and antiexocrine chemotherapy. A fistula is a communication between two epithelial or endothelial surfaces, lined by granulation tissue. It can be a life-threatening condition.
