    ABSTRACT: Toxocariasis in man is associated with three syndromes which are visceral larva migrans, ocular larva migrans and covert toxocariasis. Although neurotoxocariasis is defined as the fourth syndrome of toxocariasis, it is usually considered as a neurological disease which is usually concomitant with visceral larva migrans. In this report, a case of brain abscess caused by toxocariasis was presented. A 56 years-old female patient was admitted to our hospital with headache, pain referring to right side of her face and teeth, numbness of forth and fifth finger of her right hand. Cranial diffusion weighted, dynamic magnetic resonance imaging (MRI) revealed a few non-specific intensities at supratentorial white matter, an approximately 13 x 12 mm lesion without contrast enhancement and a significant edema around the white matter in the left frontal cortex. Histologic examination after stereotactic biopsy of the lesion revealed diffuse histiocyte infiltration. A specific agent could not be detected in the histochemical examination. Western-blot test for toxocariasis in serum and cerebrospinal fluid samples were found positive. She was transferred to the infectious diseases clinic, and albendazole therapy (400 mg, q12h) was started. Albendazole treatment was completed for a total of one month following the regression of the cranial MRI findings on the 14th day of therapy. The patient is recalled for cranial MRI control three months later. However, it was noted that she continued albendazole for three months. Compared to the previous MRI, there were two stabilized T2A hyperintense lesions in left cranial hemisphere and minimally regressed lesions at the level of left frontal centrum semiovale. The patient was successfully treated with albendazole. There was no relapse after six month follow-up. This case was presented to withdraw attention to neurotoxocariasis which may be encountered although rarely in the etiology of encephalitis/ brain abscess.

    ABSTRACT: Polymerase chain reaction (PCR) method has improved the diagnosis rates for patients with community-acquired pneumonia (CAP). We aimed to evaluate the bacterial and viral etiology of hospitalized CAP cases and compare clinical and laboratory findings of patients with pure bacterial and bacterial and viral (mixed) infections. A total of 55 patients hospitalized with CAP were enrolled into the prospective study between February 2010 and December 2010. Clinical and laboratory follow-up were performed on days 0, 7 and 14. Deep tracheal aspiration samples were examined for bacterial and viral pathogens by multiplex PCR, and standard bacteriological culture method. The etiological identification rate in 50 patients for bacteria, viruses and mixed virus-bacteria combination by PCR were 62%, 4%, 32%, respectively and 60% in 55 patients by bacterial culture method. Streptococcus pneumoniae concomitant with Haemophilus influenzae (36%) and rhinovirus (16%) was very common, whereas atypical pathogens (only Mycoplasma pneumoniae) were rare (6%). Rhinovirus was the most common viral agent (20%). Recently identified viruses, human coronavirus HKU1 and human bocavirus were not detected except for human metapneumovirus (one case). There was no significant difference in terms of mean age, immune status, leukocyte count, C-reactive protein (CRP) values, hospitalization duration and CURB-65 score between bacterial and mixed viral-bacterial detections. Advanced age (p < 0.01) and higher CURB-65 score (p = 0.01) were found to be associated with increased mortality. Concomitance of bacterial and viral agents is frequent and resemble with bacterial infections alone. Further studies are needed for the clinical significance of mixed detections.

    ABSTRACT: Writing a thesis is mandatory for getting a postgraduate medical degree in Turkey. Publication of the results of the thesis in an indexed journal makes the results available to researchers, however publication rate is usually low. The aim of this retrospective observational study was to investigate the publication rate of Turkish Infectious Diseases and Clinical Microbiology, Medical Microbiology specialty theses and Microbiology doctorate theses in international peer-review journals. On August 17th 2007, the thesis database of the Council of Higher Education of the Republic of Turkey (YOK) where all specialization and doctorate theses are recorded obligatorily, was searched for Infectious Diseases and Clinical Microbiology and Medical Microbiology specialty and Microbiology doctorate theses. Assuming that publication of a thesis would last at least six months, theses dated to February 2007 and after were excluded. The publication rate of those theses was found out by searching Science Citation Index-Expanded database for thesis author and supervisor between August 17-September 12, 2007. Chi-square test was used for statistical analysis. Our search yielded a total of 834 theses dated from 1997 to 2007, however 10 of them were excluded, since they were dated to February 2007 or after. It was found that the overall publication rate was 11.4% (94/824). The publication rates for Microbiology doctorate, Medical Microbiology and Infectious Diseases and Clinical Microbiology specialty theses were 13.7% (34/249), 10.7% (33/309) and 10.2% (27/266), respectively, with no statistical significance (p> 0.05). It was determined that nine (9.6%) of the 94 published theses belonged to 1997-2001 period, whereas 85 (80.4%) were in 2002-2007 period (p< 0.05). The probable reason for this increase was thought to be related with the updated criteria of YOK carried out in 2000 for academic promotions, nevertheless the publication rate of the investigated theses in international peer-review journals was still low. Thesis is an important part of specialty and doctorate education and necessitates intense work. The created knowledge usually contains important data about the country and the world. Publication of the theses supplies dissemination of new knowledge and completes the process of a scientific study. Solutions must be generated to promote the publication of specialty and doctorate theses.

    ABSTRACT: Among hospital-associated infections, healthcare-associated central nervous system infections are quite important because of high morbidity and mortality rates. The causative agents of healthcare-associated meningitis differ according to the status of immune systems and underlying diseases. The most frequent agents are Gram-negative bacilli (Pseudomonas spp., Acinetobacter spp., Escherichia coli and Klebsiella pneumoniae) and Gram-positive cocci (Staphylococcus aureus and coagulase-negative staphylococci). There are currently several problems in the treatment strategies of healthcare-associated meningitis due to a globally increasing resistance problem. Strategies targeting multidrug-resistant pathogens are especially limited. This review focuses on healthcare-associated meningitis and the current treatment strategies with a particular focus on methicillin-resistant Staphylococcus aureus (MRSA) meningitis.

    ABSTRACT: Dear Editor,Sarcoidosis is a systemic inflammatory disorder of unknown etiology characterized by the formation of non-caseating granulomas in the involved tissues and lymph nodes. It usually involves multiple organs, including the lungs, skin, bones, muscles, eyes, heart, liver, spleen and lymph nodes [1]. Although liver is an important site of sarcoidosis, isolated hepatic involvement is quite rare [2]. In this paper it is aimed to present a case of sarcoidosis with isolated liver microabscesses.A 51-year-old woman with no known prior disease admitted to our outpatient clinic with the complaints of fever persisting for 20 days and abdominal pain. In the physical examination her length was 150 cm and her weight was 65 kg. She had fever (38 °C) and abdominal tenderness on palpation in the upper right quadrant. She had malaise and 8 kg weight loss within the previous month. Her main laboratory findings were: hemoglobin 9.7 g/dl, leukocyte 15.57 × 103/mm3, neutrophil 80.9 %, C reactive pr

    ABSTRACT: Background Tigecycline is a relatively new glycylcycline antimicrobial, active in vitro against a variety of Gram-positive and Gram-negative organisms. In this study we evaluated the outcomes of spondylodiscitis cases treated with tigecycline-including therapies retrospectively. Methods All adult (age >18 years) cases with a diagnosis of spondylodiscitis, who were treated with a tigecycline-including therapy between 2007 and 2011, were included in the study. The primary efficacy outcome was clinical success with tigecycline at the end of induction, while the secondary efficacy outcome was maintenance of success through 3 months following completion of induction. Success through induction was also compared by dosing strategy. Results A total of eight spondylodiscitis cases fulfilled the study inclusion criteria. All cases had back pain, restricted mobility, magnetic resonance findings associated with spondylodiscitis, and microbiology or pathological findings related to spondylodiscitis. All had post-neurosurgical spondylodiscitis. In five cases, tigecycline was started in accordance with the antibacterial susceptibility results from intervertebral tissue biopsy cultures, whereas in three it was started empirically. All cases had received several different antibacterials with failure before receiving tigecycline. The mean duration of tigecycline treatment was 37 ± 21 days. One case was lost to follow-up after 2 days of tigecycline. Primary and secondary success was achieved in the remaining seven cases. Conclusions These limited data suggest that tigecycline may have a role in the treatment of refractory spondylodiscitis cases.

    ABSTRACT: The aim of this study was to compare the efficacy of piperacillin/tazobactam (P/T) and cefoperazone/sulbactam (C/S) in the empirical treatment of adult neutropenic fever. Data and outcomes of low-risk adult cases with neutropenic fever and treated with P/T (4.5 g q6h) or C/S (2 g q8h) between 2005 and 2011 June were extracted from our database. Risk evaluation was made according to criteria of Multinational Association for Supportive Care in Cancer (MASCC) and a score of ≥ 21 was considered as low risk. Data were collected prospectively by daily visits and evaluated retrospectively. Primary outcome was - fever defervescence at 72 h in combination with success without modification (referring to episodes where the patient recovered from fever with disappearance of signs of infection without modification to initial empirical treatment). All-cause mortality referred to death resulting from a documented or presumed infection or unidentified reason during the treatment and 30-day follow-up period. A total of 172 patients (113 cases P/T and 59 cases C/S) fulfilled the study inclusion criteria. Persistent response in P/T arm was 73.5%, whereas it was 64.5% in C/S arm (p > 0.05). Rates of any modification were also similar in both treatment arms. All-cause mortality during the treatment and 30-day follow-up period was not significantly different (P/T: 4/113 vs. C/S: 2/59, p > 0.05). There was no severe adverse effect requiring antibiotic cessation in both cohorts. In conclusion, our data suggest that C/S may be a safe alternative to P/T in the empirical treatment of adult low-risk febrile neutropenia cases.

    ABSTRACT: Objectives We aimed to provide data on the diagnosis of tuberculous meningitis (TBM) in this largest case series ever reported. Methods Haydarpasa-1 study involved microbiologically confirmed patients for TBM in Albania, Croatia, Denmark, Egypt, France, Hungary, Iraq, Italy, Macedonia, Romania, Serbia, Slovenia, Syria, and Turkey between 2000-2012. A positive culture, PCR or Ehrlich-Ziehl-Neelsen staining (EZNs) from the cerebrospinal fluid (CSF) was mandatory for inclusion of meningitis patients. Results 506 TBM cases were included. The sensitivities of the tests were as follows: Interferon gamma (IFN-γ) release assay (IGRA, Quantiferon TB gold in tube) 90.2%, automated culture systems (ACSs) 81.8%, Löwenstein Jensen medium (L-J) 72.7%, adenosine deaminase (ADA) 29.9%, and EZNs 27.3%. CSF-ACS was superior to CSF L-J culture and CSF-PCR (p<0.05 for both). Accordingly, CSF L-J culture was superior to CSF-PCR test (p<0.05). Combination of L-J and ACS was superior to using these tests alone (p<0.05). There were poor and inverse agreements between EZNs and L-J culture (κ,-0.189); ACS and L-J culture (κ -0.172) (p<0.05 for both). Fair and inverse agreement was detected for CSF-ADA and CSF-PCR (κ,-0.299, p<0.05). Conclusions Diagnostic accuracy of TBM was increased when both ACS and L-J cultures were used together. Non-culture tests contributed to TBM diagnosis to a degree. However, due to the delays in the diagnosis with any of the cultures, combined use of nonculture tests appears to contribute early diagnosis. Hence, diagnostic approach to TBM should be individualized according to technical capacities of medical institutions with poor resources in particular.

    ABSTRACT: The aim of this study was to determine the point prevalence of nosocomial urinary tract infections (UTIs) and to investigate risk factors for pathogen type (E. coli vs. others) and extended-spectrum beta-lactamase (ESBL) positivity among nosocomial UTI patients. A questionnaire consisting of 44 questions on demographic data and risk factors of UTI cases was sent to 51 tertiary care hospitals. Univariate and multivariate analyses were conducted. The overall prevalence of UTI was 1.82% (483/26534). The prevalence of UTI was higher in intensive care units (ICUs) with 6.77% versus 1.45% outside ICUs. Hospitals of the Ministry of Health (compared to university hospitals), hospitals in less developed provinces and hospitals with bed capacity <500 had higher UTI prevalence. Patients without a urinary catheter were more likely to have received immunosuppressive therapy, current corticosteroid use, renal transplantation and uterine prolapsus and less likely to have another infection outside the urinary tract, as compared to catheterized patients. Among the 422 culture-positive patients, the most common pathogen was E.coli (45.5%). The risk factors increasing the likelihood of E.coli in urine culture were being female, history of urinary tract operation, no use of antibiotics in the preceding three months and infection outside the urinary tract. Among patients having E.coli/Klebsiella positive in culture, antibiotic use in the preceding three months and history of urinary tract operation were the independent risk factors significantly increasing the risk of ESBL. The reasons underlying the high prevalence of nosocomial UTIs, and a better understanding of the risk factors might lead to improved control of these infections.

    ABSTRACT: The aim of this study was to delineate mortality indicators in pneumococcal meningitis with special emphasis on therapeutic implications. This retrospective, multicenter cohort study involved a 15-year period (1998-2012). Culture-positive cases (n=306) were included solely from 38 centers. Fifty-eight patients received ceftriaxone plus vancomycin empirically. The rest were given a third-generation cephalosporin alone. Overall, 246 (79.1%) isolates were found to be penicillin-susceptible, 38 (12.2%) strains were penicillin-resistant, and 22 (7.1%) were oxacillin-resistant (without further minimum inhibitory concentration testing for penicillin). Being a critical case (odds ratio (OR) 7.089, 95% confidence interval (CI) 3.230-15.557) and age over 50 years (OR 3.908, 95% CI 1.820-8.390) were independent predictors of mortality, while infection with a penicillin-susceptible isolate (OR 0.441, 95% CI 0.195-0.996) was found to be protective. Empirical vancomycin use did not provide significant benefit (OR 2.159, 95% CI 0.949-4.912). Ceftriaxone alone is not adequate in the management of pneumococcal meningitis due to penicillin-resistant pneumococci, which is a major concern worldwide. Although vancomycin showed a trend towards improving the prognosis of pneumococcal meningitis, significant correlation in statistical terms could not be established in this study. Thus, further studies are needed for the optimization of pneumococcal meningitis treatment.

    ABSTRACT: In this study, we aimed to evaluate the 1-year post-treatment follow-up results of 112 patients who received pegylated interferon (PEG-IFN) for 52 weeks. HBeAg negativity/seroconversion and/or negative HBV-DNA at the end of the treatment were considered as response. Patients who had response at the end of treatment but had HBV-DNA breakthrough during 1-year follow-up were considered as relapse. The study group comprised 112 cases (34 HBeAg-positive, 78 HBeAg-negative). In HBeAg-positive and ?negative cases, end-of-treatment response rates were 2.9% and 60.2%, whereas 1-year sustained virological response rates were 0 and 33.3%, respectively. When we compared relapse cases versus cases with response at the end of 1-year follow-up, being female and having low viral load were the two parameters associated with higher response rates (Chi-square, P = 0.028; Mann?Whitney U test, P = 0.023). Overall non-response rates to PEG-IFN were high (57.1%). Results in HBeAg-positive cases were disappointing.

    ABSTRACT: Zygomycosis is a rapidly-progressive invasive fungal disease with high mortality rates. Mucor, Rhizopus, Rhizomucor and Absidia species classified in Mucorales order, are the main causative agents of zygomycosis. Uncontrolled diabetes, hematologic malignancies, long term corticosteroid use and immunosuppressive therapies are the main predisposing factors for mucormycosis. In this study, we aimed to evaluate the mucormycosis cases from Turkey published in national and international databases in the last 17 years by means of age, gender, co-morbidities, signs and symptoms, diagnostic methods, therapeutic modalities, and mortality rate by pooling analysis. In our study, two national (http://uvt.ulakbim.gov.tr, http://www.turkmedline.net) and two international (www.ncbi.nlm.nih.gov, http://apps.webofknowledge.com) databases were used. A total of 64 manuscript (34 from national and 30 from international databases) published between 1995 and 2012, which were eligible for the study criteria and accessible as full text were included in the study. A total of 151 mucormycosis patients (71 female, 80 male; mean age: 45.4 ± 21.4 years) from these studies, with definitive diagnosis of invasive fungal infections according to the criteria of European Organization for Research and Treatment of Cancer (EORTC) have been evaluated. Of 151 patients 91 (60%) were diagnosed as rhinocerebral, 42 (%27.8) were sinoorbital, 7 (4.6%) were pulmonary, 6 (3.9%) were disseminated, 3 (1.9%) were skin, and 2 (1.3%) were gastrointestinal mycormycosis. The most common symptoms and signs were; swelling of eye and face (n= 95, 63%), fever (n= 72, 48%), nasal obstruction (n= 60, 40%), headache (n= 58, 38%) and opthtalmoplegia (n= 48, 32%). The most common co-morbidity was diabetes (49%) followed by hematological malignancies (39.7%). Mycological cultures were performed for 82 patients, and fungal growth were detected in the clinical specimens of 51 cases. The distribution of strains isolated in culture were as follows: Mucor spp. (n= 19, 37.2%), Rhizopus spp. (n= 13, 25.5%), Zygomycetes (n= 9, 17.6%), Rhizopus oryzae (n= 4, 7.8%), Rhizopus spp. + yeast (n= 3, 5.9%), Rhizomucor spp. (n= 2, 3.9%) and Rhizosporium spp. (n= 1, 1.9%). In 133 patients, histopathological investigation and in 126 patients radiological examinations were performed for diagnosis. Both surgical debridement and antifungal therapy were employed in 115 patients. Four patients had received only surgical debridement and 30 only antifungal therapies. Classical amphotericin B (AMP-B) therapy for 77 cases, liposomal AMP-B for 60 cases, liposomal AMP-B + posaconazole for six cases and lipid complex AMP-B for two cases have been started as antifungal therapies. Total mortality rate was detected as 54.3% (82/151). In conclusion, despite new diagnostic tools and therapeutic agents, mortality rates in mucormycosis are still very high. For the management, mucormycosis should be considered early in risky patients, and surgical debridement together with effective antifungal therapy should be applied as soon as possible.

    ABSTRACT: Abstract Background: Vancomycin is the mainstay of treatment for methicillin-resistant Staphylococcus aureus (MRSA) meningitis. However, successful outcomes with linezolid have not been reported in a large series of patients. We conducted a single-center retrospective cohort study to compare vancomycin with linezolid in the treatment of MRSA meningitis. Methods: We extracted data and outcomes for all adult patients (age >18 years) with culture-proved MRSA meningitis who received vancomycin or linezolid between January 2006 and June 2011. A definite diagnosis of meningitis was based on the isolation of MRSA in at least one cerebrospinal fluid (CSF) culture and findings in CSF that are typical of the infection. Linezolid was given intravenously (IV) at a dosage of 600 mg q12h and vancomycin IV at 500 mg q6h. Results: A total of 8 patients with MRSA meningitis (5 male, 3 female; age [mean±SD] 61.6±13.2 years) received vancomycin and 9 patients (7 male, 2 female; age 59.1±15.6 years) received linezolid. All isolated strains of MRSA were susceptible to both vancomycin and linezolid. The rates of microbiologic success with linezolid or vancomycin, in terms of clearance of MRSA from CSF on day 5, were 7/9 and 2/8 (p=0.044, Fisher exact test). No severe adverse events occurred in either treatment arm of the study. One-month survival of the patients in whom treatment was successful microbiologically was 2/2 in the vancomycin-treated group and 4/7 in the linezolid-treated group. Minimum inhibitory concentration (MIC) data for vancomycin were available for 5/6 treatment failures with vancomycin, and the MIC for all five strains of the organism in these cases was 2 mcg/L. Conclusion: Analysis of the findings in the limited cohorts in our study suggests that linezolid is superior to vancomycin for treating MRSA meningitis, especially in cases in which there is a high MIC (2 mg/L) for vancomycin. A clinical study involving larger cohorts may increase the evidence available in relation to this question.

    ABSTRACT: In this study it was aimed to investigate the risk factors for gastrointestinal colonization by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae and Escherichia coli in intensive care unit (ICU) of anaesthesiology and reanimation, Ege University Faculty of Medicine, Izmir, Turkey. This study was performed prospectively on adult patients hospitalized in ICU of anaesthesiology and reanimation and rectal swab cultures were performed in all patients in the first 48 hours of hospitalization and every one week until discharge or death. Samples were transported to the laboratory in Stuart transport medium and were cultured on two EMB agar plates (one including 4 mg/L ceftazidime) and incubated for 48 hours. E.coli and K.pneumoniae isolates were identified by conventional methods. Antibiotic susceptibility tests were performed by disc diffusion method on Mueller Hinton agar and interpreted according to CLSI guidelines. ESBL was confirmed by double disc synergy test. A total of 140 patients (49 female 91 male; age range: 18-83 years, mean age: 56.3 years) were evaluated, and 41 (29.3%) of the patients were found to be colonized with ESBL positive E.coli (n= 39) or K.pneumoniae (n= 2). The mean time for colonization was 11.15 ± 10.91 (range between 2-39) days. Age and gender of the patients and antibiotic consumption before or during the stay in ICU of anaesthesiology and reanimation were not found to be associated with colonization (p> 0.05). However length of ICU of anaesthesiology and reanimation stay in colonized patients was longer than non-colonized patients (27.59 ± 22.52 vs. 17.78 ± 11.74 days; p< 0.05). Infectious episodes developed in 22% (9/41) of the colonized cases and three of the nine strains were isolated from the blood cultures, five from the urine cultures and one from both blood and bronchoalveolar lavage cultures. ESBL-positive E.coli or K.pneumoniae colonization was found as an independent risk factor for the development of infection (9/41 vs. 4/99 cases; p= 0.002). Forward logistic regression analysis revealed that diabetes mellitus, immunosuppresive drug use and length of intubation were associated with ESBL-positive E.coli or K.pneumoniae colonization (p< 0.05). The results of this study indicated that the risk of development of infection was significantly high in intensive care patients colonized by ESBL positive E.coli and K.pneumoniae and the identification of the related risk factors was critically important for the establishment of effective control measures.

    ABSTRACT: international nursing review Preliminary results of this study were presented as a poster presentation in 19th European Congress of Clinical Microbiology and Infectious Diseases, Helsinki 16–19 May 2009. Nursing Hepatitis Study Group (2011) Nursing students' immunisation status and knowledge about viral hepatitis in Turkey: a multi-centre cross-sectional study. International Nursing Review 58, 181–185 Background: The aims of this multi-centre cross-sectional survey were to detect Turkish nursing students' level of knowledge on viral hepatitis, to evaluate their rates of exposure to blood and to find out their hepatitis A (HAV), hepatitis B (HBV) vaccination status. Methods: This multi-centre cross-sectional study was conducted in 14 nursing schools located in the seven geographical regions of Turkey. A questionnaire composed of 47 questions on socio-demographic factors, level of knowledge on HAV, HBV, hepatitis C (HCV) immunisation status, exposure history and attitudes was applied to the study group. Results: A total of 1491 third-and fourth-year nursing students participated with an 89% response rate. The mean age of the participating students was 21.4 1.3. Their mean knowledge score was 23.7 4.6 (71/100) and was significantly higher in fourth-year students than third-year students. There were significant differences in mean scores among nursing schools. Among the participants, 85.3% had received HBV vaccine and 9.1% had received HAV vaccine. The percentage of students who signify themselves at increased risk of acquiring viral hepatitis was 97.3%. Of the students, 28.1% had sustained a needle-stick injury and 5.4% had experienced conjunctival exposure to blood. 181 Conclusions: Curriculum differences among nursing schools have a significant effect on nursing students' level of knowledge. For this reason, nursing schools should organize HBV immunisation programmes for their students to increase vaccination coverage.

    ABSTRACT: In this study, it was aimed to compare the antibacterial activity of daptomycin and vancomycin in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) meningitis (induced by ATCC 43300 MRSA strain) in experimental rabbit meningitis model. After an eight h period time of treatment, bacterial count decreased significantly in both treatment groups compared to control group (p<0.05). However, there was no statistically significant difference between treatment groups. Our results suggest that the antibacterial activity of daptomycin is similar to vancomycin in the treatment of experimental MRSA meningitis model of rabbits.

    ABSTRACT: Clinicians have usually considered malignancies during follow up of patients who have infectious diseases as a pre-diagnosis. However, malignancy and an infectious disease are seen together more rarely, with the exception of immunosuppressed patients. This presentation is a case report followed up for fever of unknown origin. The patient was admitted to the hospital with the symptoms of fever, weight loss, abdominal pain and weakness. Anemia and hypergamaglobulinemia by biochemical analyses and splenomegaly by total body computed tomography were detected. Amastigotes were seen in bone marrow aspiration smears and promastigotes were isolated in NNN medium. At the end of the Liposomal Amphotericin B treatment, control bone marrow aspiration was applied. Leishmania amastigotes were not seen, while patient was diagnosed as diffuse B cell lymphoma pathologically. (Turkiye Parazitol Derg 2013; 37: 282-4).
