Choanal fungus ball mimicking a tumour.

We report the first case of an isolated choanal fungus ball in a 28-year-old man with a previous history of nasopharyngeal carcinoma, who was treated with radiotherapy 14 years ago. The initial diagnosis was a recurrent tumour or a secondary neoplasm. Histopathological examination confirmed a fungal infection.

In vitro susceptibility of enterococci strains isolated from urine samples to fosfomycin and other antibiotics.

Enterococci are mostly isolated from urinary tract infections (UTIs). Increasing antibiotic resistance affects the success rate in empirical treatment, thus makes antibiotic susceptibility tests important. The aim of this study was to determine the species distribution and resistance patterns of Enterococcus strains isolated from urine samples to antibacterial agents including fosfomycin in a teaching hospital, Istanbul.

Neurobrucellosis with transient ischemic attack, vasculopathic changes, intracerebral granulomas and basal ganglia infarction: a case report.

Introduction: Central nervous system involvement is a rare but serious manifestation of brucellosis. We present an unusual case of neurobrucellosis with transient ischemic attack, intracerebral vasculopathy granulomas, seizures, and paralysis of sixth and seventh cranial nerves.

Case Presentation: A 17-year-old Caucasian man presented with nausea and vomiting, headache, double vision and he gave a history of weakness in the left arm, speech disturbance and imbalance.

[Malaria: an evaluation of 40 cases].

In this study, the epidemiological, clinical, laboratory and therapeutic features of forty adult malaria patients referred our clinic between February 1996-September 2009, were assessed retrospectively. Diagnosis was established by Giemsa-stained thick and/or thin blood smears in all cases. Thirty-four patients were male and 6 patients were female and mean age was 31.

Incidence, etiology and risk factors associated with mortality of nosocomial candidemia in a tertiary care hospital in Istanbul, Turkey.

Objective: The aim of this study was to determine the incidence, etiology and risk factors for mortality of patients with nosocomial candidemia.

Subjects And Methods: This observational study was performed at Haydarpasa Numune Training and Research Hospital, a tertiary care hospital with 750 beds, between the years 2004 and 2007. Fifty defined cases with a nosocomial bloodstream infection caused by Candida species were included in the study.

Unusual central nervous system involvement of rheumatoid arthritis: successful treatment with steroid and azathioprine.

Central nervous system involvement of rheumatoid arthritis (RA) frequently develops in patients who had a long-term history of RA, irrespective of the disease activity of systemic arthritis, and it has a high mortality rate despite treatment. Since clinical symptoms and radiologic signs are rather nonspecific, in short of doing biopsy, the diagnosis of rheumatoid meningitis is one of exclusion. However, the strongly positive rheumatoid factor in the cerebrospinal fluid is quite specific.

Incidence, etiology, and antibiotic resistance patterns of gram-negative microorganisms isolated from patients with ventilator-associated pneumonia in a medical-surgical intensive care unit of a teaching hospital in istanbul, Turkey (2004-2006).

The identification of microorganisms causing ventilator-associated pneumonia (VAP) is important for formulating appropriate therapies. In this study, we report the incidence, etiology, and antibiotic resistance patterns of Gram-negative microorganisms isolated from patients diagnosed with VAP in our medical-surgical intensive care unit (ICU) during the years 2004-2006. VAP was diagnosed by using the clinical criteria of the Centers for Disease Control and Prevention.
