Synergism between quinine and retinol in fresh isolates of Plasmodium falciparum.

Following earlier reports of synergism between retinol and various antimalarial compounds, the pharmacodynamic interaction between retinol and quinine was investigated in 38 fresh isolates of Plasmodium falciparum. The study was carried out in western Thailand, an area with quinine-resistant P. falciparum.

Clinical features, etiology and short term outcomes of interstitial pneumonitis in HIV/AIDS patients.

A prospective study was conducted at Bamrasnaradura Hospital, Nonthaburi Province, Thailand from November 11, 2002 to January 5, 2003. A total of 59 HIV/AIDS patients with interstitial infiltrates on chest radiographs were included in the study. The objectives of this study were to describe the clinical manifestations and determine the etiologies of interstitial pneumonitis, assess the short-term outcomes and determine the accuracy of the clinical diagnosis of the etiologies of interstitial pneumonitis in HIV/AIDS patients at Bamrasnaradura Hospital, Nonthaburi, Thailand.

Clinical features, aetiology and short-term outcome of interstitial pneumonitis in HIV/AIDS patients at Bamrasnaradura Hospital, Nonthaburi, Thailand.

This prospective study was conducted at Bamrasnaradura Hospital from November 11, 2002, until January 5, 2003, in order to describe the clinical manifestations and determine the aetiologies as well as to assess the short-term outcome of interstitial pneumonitis in HIV/AIDS patients. 59 patients with interstitial infiltrates on chest radiographs were included in the study. Tuberculosis (TB) was the most common diagnosis (44%), followed by Pneumocystis pneumonia (PCP) (25.

In-vitro response of Plasmodium falciparum to the main alkaloids of Cinchona in northwestern Thailand.

The blood schizontocidal activity of the four main Cinchona alkaloids against Plasmodium falciparum was compared in 46 fresh parasite isolates, using an in-vitro test measuring the drug-specific inhibition of schizont maturation. The studies were conducted in June-August 2001 at Mae Sot, northwestern Thailand, an area where quinine alone is no longer able to eliminate infections with P. falciparum.

Effect of hospitalization and antimicrobial therapy on antimicrobial resistance of colonizing Staphylococcus epidermidis.

Endogenous infections with multi-resistant S. epidermidis are among the leading causes of nosocomial infections. The effect of hospitalization and antimicrobial therapy on antimicrobial resistance of colonizing staphylococci was determined from swabs of the nose, hand, axilla and groin from 157 patients on one day.
