To determine the extent of extraneural lesions in buckthorn poisoning, 180 CD1 mice were administered either green or ripe fruit or toxins T-544 or T-514 obtained from the fruit of the plant and were observed over a period of three weeks. Marked weakness, hyporeflexia, hair bristling, ptosis, spinal deformity, weight loss and dypsnea were prominent signs.(More)
Intoxication by Karwinskia humboldtiana (buckthorn) fruit presents a neurological picture similar to that of Guillain-Barré syndrome. In this report, we describe an experimental animal model of peripheral neuropathy induced by buckthorn fruit. Four groups of Wistar rats received one oral dose of 1.5 g/kg followed by oral doses of 0.5 g/kg at days 3, 7, 10,(More)
Previous acute toxicity studies with 'Tullidora' in mice showed mainly hepatic and pulmonary complications. We tested samples in rat, guinea-pig, hamster and dog, searching for the mechanism of death. A single oral preparation of ripe fruit of Karwinskia humboldtiana was given to all animals. Clinical signs and histopathology were reproduced in all species(More)
The Gram-positive cocci (GPC), Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis and Enterococcus faecium, have become important causes of community and nosocomial-acquired infections. The prevalence of multiple resistant isolates to standard antimicrobial drugs has significantly increased over the past decades. Few prospective studies(More)
The antimicrobial resistance patterns of 2,462 selected Gram-positive cocci obtained from three Community-Private Hospitals (CPH) and three University-Affiliated Hospitals (UAH) were evaluated utilizing the institutions' antimicrobial susceptibility reports for the year 2000. The objectives of this study were: 1) to evaluate the in vitro resistance to(More)
Intoxication by Karwinskia humboldtiana presents a neurological picture similar to that for Guillain-Barré syndrome or other polyradiculoneuropathies. Clinical diagnosis in poisoned humans may be difficult if no evidence of previous fruit ingestion is available. We present our experience in the clinical diagnosis of Karwinskia humboldtiana polyneuropathy,(More)
Accidental extravasation of vesicant chemotherapy may cause important tissue injuries. Nowadays, the majority of authors propose topical dimethyl sulfoxide (DMSO), with or without local cooling, as the treatment of choise efor anthracyclines extravasation. No significant toxicity has been reported when DMSO is used as topical treatment. This report(More)
Few studies have been performed in Puerto Rico concerning the antimicrobial resistance pattern of clinically significant Gram-negative bacilli. The antimicrobial resistance patterns of 5,590 Gram-negative bacteria obtained from three Community-Private Hospitals (CPH) and three University-Affiliated Hospitals (UAH) were evaluated utilizing the institutions'(More)
