Surgical pulmonary vein isolation by ablation as a treatment for atrial fibrillation was first performed in isolation in 1996 at Hospital de Santa Cruz in Portugal, as a complementary therapy to mitral valve surgery in patients with rheumatic mitral valve disease, in order to reduce the morbidity associated with maze surgery. This innovative surgical approach, performed by Queiroz e Melo, repla...

emergency departments (eds) are the most challenging ward with respect to patient delay. the goal of this study is to present strategies that have proven to reduce delay and overcrowding in eds. in this review article, initial electronic database search resulted in a total of 1006 articles. thirty articles were included after reviewing full texts. inclusion criteria were assessments of real pat...

Biotransformation products of the atypical neuroleptic clozapine were isolated from urine samples of three schizophrenic patients by solid-phase extraction, liquid-liquid extraction for the separation of unpolar and polar metabolites, and thin-layer chromatography followed by final purification by high-performance liquid chromatography. Their structures were elucidated by mass spectrometry and ...

We describe a case of Salmonella paratyphi A isolated from urine of a 37-year-old Saudi patient who is a known case of nephrolithiasis and hydronephrosis with frequent admission for management of renal stones. History of enteric fever was not documented and urinary schistosomiasis in such a patient from endemic area is a strong possibility. Relevant literature was discussed.

The patient, a 40-year-old man, had cerebrospinal fluid rhinorrhea before the meningitis developed. Acanthamoeba culbertsoni was repeatedly demonstrated in and cultured from the cerebrospinal fluid. The patient responded dramatically to a combinati...

The genus Arcobacter currently includes four species (7). Two species, Arcobacter cryaerophilus and Arcobacter butzleri, have been associated with human disease. They were mainly isolated from patients with diarrhea and bacteremia (2, 3, 6). Arcobacter nitrofigilis has been associated with roots of a salt marsh plant, Spartina alterniflora. The fourth species, Arcobacter skirrowii, has been rec...

OBJECTIVES Acute appendicitis is a common surgical emergency. The etiology and pathophysiology of appendicitis have been well investigated. Aggregatibacter aphrophilus is a fastidious gram-negative coccobacilli. Detection of this organism in clinical samples and its differentiation from Haemophilus aphrophilus or from Aggregatibacter actinomycetemcomitans in routine microbiology settings could ...
