The treatment of hydatid cyst includes various forms: from open surgery to laparoscopic and endoscopic therapies, all enhanced by specific antiparasitic drugs. In this chapter are summarized the main techniques of laparoscopic treatment of hydatid cyst and its major postoperative complications. Surgical techniques described vary depending on the topographic location, expression on the surface o...

Drug repurposing approaches have the potential advantage of facilitating rapid and cost-effective development of new therapies. Particularly, the repurposing of drugs with known safety profiles in children could bypass or streamline toxicity studies. We employed a phenotypic screening paradigm on a panel of well-characterized cell lines derived from pediatric solid tumors against a collection o...

Overview of the Issue P-glycoprotein, encoded by the MDR1 (also known as the ABCB1 gene) plays an important role in the absorption, distribution, metabolism and excretion of many drugs. It is not surprising, then, that dysfunction of P-glycoprotein increases susceptibility to drug toxicity (antiparasitic agents, anti-diarrheal drugs, chemotherapeutic drugs, acepromazine, butorphanol and others)...

Metronidazole (MDZ) and related 5-nitroimidazoles are the recommended drugs for treatment of trichomoniasis, a sexually transmitted disease caused by the protozoan parasite Trichomonas vaginalis. However, novel treatment options are needed, as recent reports have claimed resistance to these drugs in T. vaginalis isolates. In this study, we analyzed for the first time the in vitro effects of the...

Chagas disease, which was once thought to be confined to endemic regions of Latin America, has now gone global, becoming a new worldwide challenge with no cure available. The disease is caused by the protozoan parasite Trypanosoma cruzi, which depends on the production of endogenous sterols, and therefore can be blocked by sterol 14α-demethylase (CYP51) inhibitors. Here we explore the spectral ...

Deriving adequate withdrawal intervals for extralabel use of veterinary topical products is difficult because there are limited published data, and data for approved drugs and pesticides are usually proprietary. Where possible, approved products and doses labeled for the specific indication at hand should be used and label withdrawal times should be adhered to. When determining whether topical ...

Therapeutic products quite often are causes of poisoning in both small and large animals. Drug poisonings in animals occur commonly due to off-label use of medicines, wrong dosage, negligence, accidental ingestion and deliberate poisonings. Toxicity of veterinary drugs may become evident also in therapeutic doses when adverse effects may occur. The aim of this review is to inform veterinary spe...

Susceptibility testing was performed on Dientamoeba fragilis ATCC 30948 in a dixenic culture with Klebsiella pneumoniae and Bacteroides vulgatus. D. fragilis was cocultured with the bacteria in TYGM-9 medium (ATCC medium 1171). The activities of antiparasitic drugs were assessed by counting viable D. fragilis trophozoites with a hemacytometer by trypan blue exclusion. The minimal amebicidal con...

Chagas' disease is an endemic disease in Latin America caused by a unicellular parasite (Trypanosoma cruzi) that affects almost 18 million people. This condition involves the heart, causing heart failure, arrhythmias, heart block, thromboembolism, stroke, and sudden death. In this article, we review the current and emerging treatment of Chagas' cardiomyopathy focusing mostly on management of he...
