It has a broad spectrum of clinical manifestations, among which cerebral gumma is, a kind of neurosyphilis, however, it is rare and can be cured by penicillin. Thus, cerebral gumma needs to be differentially diagnosed from other brain masses(More)
The nature and distribution of hepatitis C virus (HCV) genotypic variants present in south-east Asia have not been extensively investigated. We analysed HCV RNA obtained from 67 clinical serum samples from Singapore, Thailand, Indonesia, the Philippines and South Korea. All samples were amplified by semi-nested RT-PCR and the nucleotide sequence determined(More)
Scrub typhus, which is caused by Orientia tsutsugamushi, has various systemic manifestations, including GI symptoms. We describe one patient with scrub typhus who presented with symptoms that suggested acute appendicitis and another who presented with symptoms of acute cholecystitis. The first patient underwent appendectomy, which revealed no pathological(More)
The susceptibility of 424 bacterial isolates causing diarrhoea were tested by agar dilution technique on Mueller-Hinton Agar against amoxicillin, ampicillin, ceftriaxone, chloramphenicol, co-trimoxazole, ciprofloxacin, doxycycline, norfloxacin and ofloxacin. The bacterial species included were Aeromonas hydrophila, Edwardsiella tarda, Pleisomonas(More)
During drug treatment of tuberculous lymphadenitis, paradoxical response (PR) may occasionally occur. Continued treatment or lymph node aspiration improves PR without severe sequelae. However, we report a case of severe PR in a patient with cervical lymph node tuberculosis causing airway obstruction due to retropharyngeal lymph node swelling during(More)
Fluoroquinolones (FQs) represent a major class of antimicrobials that have a high potential as therapeutic agents. Although FQs are generally safe for the use as antimicrobials, they may induce tendinopathic complications such as tendinitis and tendon rupture. A number of factors have been suggested to further predispose a patient to such injuries.(More)
The pharmacokinetics of 400 mg norfloxacin administered orally were studied in 19 patients both during the acute phase of bacterial gastroenteritis and during convalescence, after normalization of bowel movements. The peak serum concentrations, total area under the serum concentration curve, rate of elimination and serum half-life in the beta-phase were all(More)
