Proactive environmental surveillance for Legionella pneumophila in hospitals that treat immunocompromised patients is a useful strategy for preventing nosocomial Legionnaires' disease. We report the presence of L. pneumophila serogroup 1 in 15.2% of the water systems of our tertiary healthcare center, which should prompt health officials to formulate mitigation policies.

The incidence and patterns of and factors associated with inappropriate antibiotic use were studied in a tertiary care center in Thailand. The incidence of inappropriate antibiotic use was 25%. Admission to the surgical department (adjusted odds ratio, 2.0; P=.02) and to the obstetrics and gynecology department (adjusted odds ratio, 2.0; P=.03) were associated with inappropriate antibiotic use,...

Guillain-Barré syndrome (GBS) cases admitted to Canadian pediatric tertiary care centers were ascertained through active surveillance. From 1996 to 2012, 246 cases were identified, and 24 (10%) had onset ≤30 days after immunization. Annual rate of postimmunization GBS was 2.0 per 100,000 hospitalizations. Postimmunization GBS was an infrequent cause of pediatric hospitalization.

With recent findings in arthritis and dementia, it has become apparent that Lyme treponemes and oral treponemes have tertiary clinical findings similar to tertiary syphilis. The primary findings are in the skin or mucous membranes with syphilis demonstrating a chancre, Lyme disease erythema chronicum migrans, and oral treponemes dental plaque.

In our first 200 cases of primary hyperparathyroidism confirmed by operation 12 were also shown to have a long history either of a malabsorption syndrome or of chronic renal-glomerular failure. We consider that they first went through a phase of secondary hyperparathyroidism, during which one or more of the glands became autonomous adenamata. This then produced the biochemical changes of "prima...

Parikh matrix is a numerical property of a word on an ordered alphabet. It is used for studying word in terms of its sub words. It was introduced by Mateescu et al. in 2000. Since then it has been being studied for various ordered alphabets. In this paper Parikh Matrices over tertiary alphabet are investigated. Algorithm is developed to display Parikh Matrices of words over tertiary alphabet. T...
