ABSTRACT

BACKGROUND: High-risk (HR) Human Papillomavirus (HPV) has been shown to play an important role in men in various locations in Turkey. This study aims to screen the male persistent infection with the high-risk human papillomavirus (HPV) genotype status in Turkey to provide a reference basis for formulating prevention strategies for the development of genitourinary tract neoplasia. METHODS: The HPV QUANT-21 Quantitative RT-PCR Kit® was used to identify and quantify low-risk HPV (HPV 6, 11, 44) and high-risk (HPV 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82) from male individuals in Turkey. RESULTS: Of the total 1304 samples, 473 were positive for at least one HPV genotype, with an overall frequency of 36.2%. Two-hundred fifty-four patients were positive only for one or more LR   HPV genotypes (54%), and 219 patients were positive for one or more HR HPV genotypes (46%). The LR HPV genotype frequency was 53.7%, while the HR HPV genotype frequency was 46.3%. Our technology had the positive advantage of being able to calculate concentrations for each genotype. Genotype 51 was second in frequency but had the highest average concentration of 5.38 log (copies/sample). CONCLUSION: The presence and genotype of the virus before HPV vaccination are also of increasing importance. The data obtained will serve as a guide for prevention strategies, especially vaccination. Based on our findings there is a need of new estimates of the efficacy of currently available HPV vaccines and to develop a screening program to prevent and reduce the incidence of genitourinary tract neoplasias in Turkey. Further studies are planned to measure and define the high levels of infection that may lead to the development of cervical tumors. Using this technique, it may be possible to make clinical decisions about the extent of cytological alterations.

ABSTRACT

BACKGROUND: Persistent infection with high-risk (HR) Human Papilloma Virus (HPV) genotypes has been shown to play a significant role in the development of cervical intraepithelial neoplasia (CIN) and CC (cervical cancer). The present study aimed to determine the distribution and quantification of viral load of HPV genotypes in numerous genital samples obtained from women undergoing routine gynaecological care in different regions of Turkey. METHODS: HPV typing was done by HPV QUANT-21 Quantitative RT-PCR Kit®, which is intended for the specific identification and quantification of low-risk (HPV 6, 11, 44) and high-risk (HPV 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82) from female subjects in Turkey. RESULTS: From the total of 5975 samples, 2777 were positive for at least one HPV genotype, with an overall frequency of 46.4%. 1695 patients were positive for only one or more LR-HPV genotypes (61%) and 812 patients were positive for one or more HR-HPV genotypes (29%). The frequency of LR-HPV genotypes was 31.4%, while the frequency of HR-HPV genotypes was 118.8%. Our tecnology had a positive advantage to calculate the concentration of each genotypes. Although genotype 52 ranked fifth in frequency, it showed the highest mean concentration, with a value of 5.38 log (copies/sample). CONCLUSION: The presence and genotype of viruses before HPV vaccination have also gained importance. The data obtained would provide guidance for prevention strategies, mainly of vaccination. We decided to add a new estimate to the effectiveness of currently available HPV vaccines and the development of screening programs to prevent and decrease the incidence of CC in Turkey. Further studies would be planned to measure and define the high infection level that can lead to the development of cervical neoplasia. Using this tecnology could give us a clinical desicion to degree the cytological changes.

ABSTRACT

BACKGROUND: The fatality attributed to pandemic influenza A H1N1 was not clear in the literature. We described the predictors for fatality related to pandemic influenza A H1N1 infection among hospitalized adult patients. METHODS: This is a multicenter study performed during the pandemic influenza A H1N1 [A(H1N1)pdm09] outbreak which occurred in 2009 and 2010. Analysis was performed among laboratory confirmed patients. Multivariate analysis was performed for the predictors of fatality. RESULTS: In the second wave of the pandemic, 848 adult patients were hospitalized because of suspected influenza, 45 out of 848 (5.3%) died, with 75% of fatalities occurring within the first 2 weeks of hospitalization. Among the 241 laboratory confirmed A(H1N1)pdm09 patients, the case fatality rate was 9%. In a multivariate logistic regression model that was performed for the fatalities within 14 days after admission, early use of neuraminidase inhibitors was found to be protective (Odds ratio: 0.17, confidence interval: 0.03-0.77, p=0.022), nosocomial infections (OR: 5.7, CI: 1.84-18, p=0.013), presence of malignant disease (OR: 3.8, CI: 0.66-22.01, p=0.133) significantly increased the likelihood of fatality. CONCLUSIONS: Early detection of the infection, allowing opportunity for the early use of neuraminidase inhibitors, was found to be important for prevention of fatality. Nosocomial bacterial infections and underlying malignant diseases increased the rate of fatality.

ABSTRACT

The aim of the present study was to determine the rate of device-associated infection (DAI) and the change in profiles and antimicrobial resistance patterns of the causative microorganisms in a medical-surgical intensive care unit (ICU), as well as to evaluate the effect of a new nationwide hospital infection control program (NHICP), which has been implemented in Turkey. In this study, 5,772 patients that were hospitalized for a total of 43,658 days acquired 1,321 DAIs, with an overall rate of 30.2% per 1,000 ICU days. Between 2004 (before the NHICP) and 2010, the incidence densities of catheter-associated urinary tract infection (CAUTI) decreased from 10.2 to 5.7 per 1,000 device-days (P < 0.0001), and central venous catheter-associated bloodstream infection (CVC-BSI) decreased from 5.3 to 2.1 per 1,000 device-days (P < 0.0001). However, ventilator-associated pneumonia increased from 27.0 to 31.5 per 1,000 device-days. Multidrug-resistant species rates increased from 5.8% to 76.6% (P < 0.0001) for Acinetobacter spp. and from 6.8% to 53.1% (P < 0.0001) for Pseudomonas aeruginosa. The extended-spectrum ß-lactamase-producing Enterobacteriaceae rate increased from 23.1% to 54.2% (P = 0.01); the vancomycin-resistance rate among Enterococcus spp. increased from 0% in 2004 to 12.5% in 2010 (P = 0.0003). In conclusion, while a significant decrease was achieved in the incidences of CAUTI and CVC-BSI, the NHICP was not completely effective in our ICU. The high incidence of DAI and the increasing prevalence of multidrug-resistant microorganisms indicate that further interventions are urgently needed.

ABSTRACT

Brucellosis is a zoonotic infection and has endemic characteristics. Neurobrucellosis is an uncommon complication of this infection. The aim of this study was to present unusual clinical manifestations and to discuss the management and outcome of a series of 18 neurobrucellosis cases. Initial clinical manifestations consist of pseudotumor cerebri in one case, white matter lesions and demyelinating syndrome in three cases, intracranial granuloma in one case, transverse myelitis in two cases, sagittal sinus thrombosis in one case, spinal arachnoiditis in one case, intracranial vasculitis in one case, in addition to meningitis in all cases. Eleven patients were male and seven were female. The most prevalent symptoms were headache (83%) and fever (44%). All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months) was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

ABSTRACT

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. All demographic, microbiological and clinical records for each patient were collected using a standardized form. Blood culture was performed by automated blood culture system, and those samples positive for yeast were subcultured on Sabouraud agar. RESULTS: The mean incidence density of nosocomial candidemia was 0.58/10,000 patient-days/year (range 0.17-1.4). Candidemia episodes increased from 0.17/10,000 to 1.4/10,000 patient-days/year (p < 0.0001). Candida albicans and non-albicans Candida accounted for 15 (30%) and 35 (70%) cases, respectively. The overall mortality was 56% and was significantly associated with stayingin the intensive care unit (odds ratio: 3.667, 95% confidence interval: 1.07-12.54, p = 0.034). CONCLUSION: This study showed that there was a significantly increased trend in the incidence of candidemia with high mortality during the study period.

ABSTRACT

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 31.1 years. All patients had a history of travel to endemic areas (24 cases to Africa, Afghanistan, Azerbaijan, Arabian Peninsula, 16 cases to Southestern Anatolia Region), and none of them had chemoprophylaxis. Plasmodium vivax was detected in 20 patients, and P.falciparum in 18 and mixed (P. vivax and P. falciparum) in two. Parasitemia ranged from 0.5%- 25%. Fever (100%), periodic fever (62.5%), splenomegaly (72.5%), hepatomegaly (45.0%), anemia (67.5%), leukopenia (32.5%), thrombocytopenia (75.0%), a rise in erytrocyte sedimentation rate (65.0%), abnormalities in hepatic enzymes (62.5%), hyponatremia (32.5%), hypoglisemia (25%) and an elevated serum creatinine level (27.5%) were determined in the patients. Two patients with P. falciparum developed acute renal failure and cerebral involvement died soon after admission. Acute renal failure, acute respiratory distress syndrome, cerebral involvement and dissemine intravasculer coagulation were observed in one patient with falciparum malaria who recovered completely. In conclusion, every febril patients with a history of travel to the endemic regions should raise the suspicion of malaria. Effective pre-exposure chemoprophylaxis and personal protection measures should be provided to travellers visiting endemic regions.

ABSTRACT

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. Physical examination revealed fever, doubtful neck stiffness and left abducens nerve paralysis. An analysis of his cerebrospinal fluid showed a pleocytosis (lymphocytes, 90%), high protein and low glucose levels. He developed generalized tonic-clonic seizures, facial paralysis and left hemiparesis. Cranial magnetic resonance imaging demonstrated intracerebral vasculitis, basal ganglia infarction and granulomas, mimicking the central nervous system involvement of tuberculosis. On the 31st day of his admission, neurobrucellosis was diagnosed with immunoglobulin M and immunoglobulin G positivity by standard tube agglutination test and enzyme-linked immunosorbent assay in both serum and cerebrospinal fluid samples (the tests had been negative until that day). He was treated successfully with trimethoprim and sulfamethoxazole, doxycyline and rifampicin for six months. CONCLUSIONS: Our patient illustrates the importance of suspecting brucellosis as a cause of meningoencephalitis, even if cultures and serological tests are negative at the beginning of the disease. As a result, in patients who have a history of residence or travel to endemic areas, neurobrucellosis should be considered in the differential diagnosis of any neurologic symptoms. If initial tests fail, repetition of these tests at appropriate intervals along with complementary investigations are indicated.

ABSTRACT

Uncomplicated lower urinary tract infections (UTIs) are the most frequent infections in females. Increased resistance rates against commonly used antibiotics have led to the use of novel antimicrobials. The aim of the present study was to evaluate the bacteriological and clinical effects of single-dose fosfomycin trometamol (FMT) and 5-day ciprofloxacin in females with uncomplicated UTIs. In this randomized comparative study, 260 female patients between 18 and 65 years of age enrolled, of whom 142 completed the study. The most frequently isolated bacterial pathogen in the urine cultures of patients were Escherichia coli (82.3%) and Enterobacter spp. (8.4%). FMT sensitivity was 94% and ciprofloxacin sensitivity was 59% in Escherichia coli; in comparison, FMT sensitivity was 75% and ciprofloxacin sensitivity was 50% in Enterobacter spp. The MIC90 for FMT was 4 µg/ml. Of the 142 patients, 77 were treated with FMT and 65 were treated with ciprofloxacin. The clinical remission rate was 83% in the FMT group and 81% in the ciprofloxacin group; the bacterial eradication rate was 83% in the FMT group and 78% in the ciprofloxacin group, and there was no significant difference between the two study groups. In conclusion, a single dose of FMT (at 3 g) was as effective as ciprofloxacin, at 500 mg twice a day for 5 days, in the treatment of uncomplicated lower UTIs. It was concluded that the use of FMT as a first-line treatment in the empirical treatment of uncomplicated UTIs might have a positive impact on the problem of resistance to other antibiotics.

ABSTRACT

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. Antibiotic resistance patterns of isolated microorganisms were defined by standard methods. The VAP incidence rate was 22.6/1,000 ventilator days. The most frequently isolated pathogens were Acinetobacter spp., methicillin-resistant Staphylococcus aureus, and Pseudomonas aeruginosa. Ninety percent of Acinetobacter spp. isolates were resistant to ceftazidime, 64% to imipenem, and 80% to ciprofloxacin. Fifty-nine percent of P. aeruginosa isolates were resistant to ceftazidime, 32% to imipenem, and 62% to ciprofloxacin. Cefoperazone-sulbactam was the most active agent against Acinetobacter spp. In conclusion, the incidence of VAP and the prevalence of multidrug-resistant microorganisms are quite high in our ICU. Comparison of the resistance rates of isolates demonstrates that certain antibiotic agents are more effective than others.

ABSTRACT

BACKGROUND: Nosocomial meningitis is a rare complication following neurosurgical procedures and is associated with high morbidity and mortality. AIM: The aim of this study was to describe the clinical characteristics and the risk factors associated with mortality in patients who developed nosocomial meningitis following neurosurgical operations. SETTING AND DESIGN: Tertiary care hospital and an observational study. MATERIALS AND METHODS: The study subjects included 2265 patients who underwent various neurosurgical operations during 2003-05. The diagnosis of nosocomial meningitis was based on the Center for Disease Control criteria. STATISTICAL ANALYSIS: It was performed by using Statistical Package for Social Sciences for Windows 10.0 program. RESULTS: The incidence of postoperative nosocomial meningitis was 2.7% (62 episodes in 49 patients among 2265 patients operated). Staphylococcus aureus and Acinetobacter spp. were the most frequently isolated pathogens. Of the 49 with meningitis 20 (40.8%) patients died. In the logistic regression analysis model, Glascow coma scale score less than 10 (Odds Ratio (OR): 19.419, 95% Confidence Interval (CI); 1.637-230.41, P = 0.001), and low cerebrospinal fluid glucose level (< or = 30 mg/ dL) (OR: 10.272, 95% CI; 1.273-82.854, P = 0.002), and presence of concurrent nosocomial infection (OR: 28.744, 95% CI;1.647-501.73, P =0.001) were the independent risk factors associated with mortality. CONCLUSION: The mortality in patients who developed meningitis was high. The high percentage of concurrent nosocomial infections was associated with a high mortality rate which was a serious problem.

ABSTRACT

OBJECTIVES: Although the decline of the morbidity and mortality in recent years, brain abscess is still one of the most important problems in Neurosurgery. METHODS: Ninety-six patients with brain abscess are analysed retrospectively, that treated between 1988 and 2001, according to age, the clinical symptoms, etiologic factors, infecting organisms, prognostic factors, localization, diagnostic and treatment methods and outcome. RESULTS: Seventy-two patients treated with aspiration (streotactic aspiration in 12 cases), 14 patients with excision. Ten patients treated medically alone. Seven patients in the aspiration group and one patient in the excision group were died. Cure without any morbidity obtained in 55 patients. A significant correlation determined with initial neurologic grade, meningismus, high fever (>38.50), leucocytosis (>20.000/mm3) and mortality. There were no significant correlation the age groups and outcome, treatment groups and location of abscess, period of treatment, number of abscess, outcome according to GOS and factor, treatment period and received antibiotic. CONCLUSIONS: In appropriate cases, medical treatment can be successful alone but surgery, aspiration, is gold standard for brain abscesses. In that way, definite diagnosis is obtained and pathogen is identified and cure is obtained in a short time.

ABSTRACT

OBJECTIVES: In this study, the determination of Helicobacter pylori (H. pylori) by culture, histopathological and serological methods in cases of endoscopically diagnosed as duodenitis and duodenal ulcer (DU), a comparison of their relative advantages, and its antibiotic sensitivities were investigated. METHODS: Helicobacter pylori was investigated using 3 methods (culture, histopathological and serological examination) in 50 patients (25 diagnosed with duodenitis and 25 with DU) at the Department of Gastroenterohepatology, Istanbul Haydarpasa Numune Hospital, Turkey between December 2000 and February 2001. An investigation into its antibiotic sensitivities to amoxicillin, clarithromycin, metronidazole and azithromycin by disc diffusion methods and to amoxicillin and clarithromycin by E-test were investigated. RESULTS: Helicobacter pylori bacteria were observed in Gram stained preparates prepared from biopsy material in 34 out of 50 patients (68%), and were able to be produced in active culture in all these cases. Histopathological examination revealed the presence of H. pylori in 80% cases of DU and 60% cases of duodenitis; anti-CagA(IgG) was positively determined in 88% DU cases and in 60% duodenitis cases. There was a significant difference between the 2 groups in terms of diagnosis by histopathological and serological methods. The difference between the 2 groups produced in active culture in 84% cases of DU cases and 52% of duodenitis was statistically significant (p=0.0322). Using the E-test and disc diffusion methods, 8.8% of the strains that reproduced in culture were resistant to and 91.2% were sensitive to clarithromycin. All strains were determined to be sensitive to amoxicillin: 17.6% of the strains were determined to be resistant to metronidazole, 11.7% to azithromycin. CONCLUSION: It was observed that Gram staining is a rapid and reliable method of pre-diagnosis for H. pylori; that histopathological examination methods are of considerable importance in diagnosis; and that the investigation of the positivity of anti-CagA(IgG) will be a guide in the identification of virulent strains in particular. In addition, it was also concluded that since serological examination does not require invasive measures, this will pose an advantage. The culture method can be applied with the aim of diagnosis in cases identified as DU using endoscopy, and that in cases resistant to treatment it can be applied for the purpose of determining antimicrobial sensitivity. E-test and disc diffusion methods exhibited a rather good correlation, for which reason the disc diffusion method can be used in the determination of antimicrobial sensitivity in H. pylori strains.

ABSTRACT

The group G streptococcal endocarditis is a rare form of infective endocarditis. In this form of infective endocarditis, serious neurological complications most commonly develop. We reported this case because of its being an unusual form of infective endocarditis that was caused by Group G Streptococcus. We also reviewed the literature. The patient was admitted to infectious disease service with a presumptive diagnosis of central nervous system infection. Blood cultures were positive for group G streptococcus. There was a mass on the posterior surface of the mitral valve which was 2 x 2.5 cm in length on the echocardiography. In the cranial computerized tomography of our patient, slightly increased contrast media uptake was observed in the both parietal lobes, in the both frontal lobes, and in the anterior areas of right occipital lobe. Therefore, this case was assumed as infective endocarditis caused by group G streptococcus with multiple cerebral emboli. Ceftriaxone was given for 4 weeks and gentamicin was given for 2 weeks, and progressive improvement of the patient's condition was seen.

ABSTRACT

This study evaluated the in vitro effects of the combination of a carbapenem (imipenem or meropenem) with a quinolone (ciprofloxacin or levofloxacin) using a microbroth dilution chequerboard technique and multidrug-resistant Pseudomonas aeruginosa strains. The ciprofloxacin and meropenem combination was only synergistic against 2 strains (6.2%) and ciprofloxacin and imipenem against 1 strain (3.1%). Levofloxacin and imipenem or meropenem were not synergistic for against any strain. None of the combinations showed an antagonistic effect.
