- PublicationMetadata onlyA case of cerebral phaeohyphomycosis caused by Fonsecaea monophora, a neurotropic dematiaceous fungus, and a review of the literature(2015-03-01) Doymaz, Mehmet Z.; Gultepe, Bilge S.; Hakyemez, Ismail; CEVIK, Serdar; ASLAN, Turan; DOYMAZ, MEHMET ZIYA; SEYİTHANOĞLU, MEHMET HAKAN; HAKYEMEZ, İSMAİL NECATİ; SÜMBÜL, BİLGEThe Fonsecaea species, which are the leading causes of chromoblastomycosis, are not considered neurotropic fungal agents. Fonsecaea pedrosoi is the primary species in the genus and is usually isolated from chromoblastomycosis cases. However, the recently distinguished species F. monophora has been reported in a few cerebral phaeohyphomycosis cases. Here, a case of cerebral phaeohyphomycosis caused by Fonsecaea monophora is presented in a 71-year-old female subject with chronic diabetes mellitus and hypertension. The identification of F. monophora was made through mycological and molecular analysis, and an isolate was differentiated from the closely related F.pedrosoi by sequence data on key bases on the ribosomal internal transcribed spacer region. The case was successfully treated with surgical and medical approaches, and the patient has remained healthy and stable after a ten-month follow up. Given the increasing incidence of this type of infection of the central nervous system (CNS), this case provides further support for the consideration that F. monophora might represent a neurotropic agent.
- PublicationMetadata onlyEvaluation of the Relationship Between ABO/Rh Blood Groups and Severity of Liver Fibrosis in Patients with Chronic Hepatitis B(2016-04-01) Hakyemez, Ismail Necati; Durdu, BÜLENT; BOLUKÇU, SİBEL; ASLAN, Turan; HAKYEMEZ, İSMAİL NECATİ; DURDU, BÜLENT; BOLUKÇU, SİBELObjective: Studies on the severity of fibrosis in chronic viral hepatitis are scarce and limited with only hepatitis C infection. The aim of this study was to determine the role of ABO-Rh blood groups in the severity of fibrosis and progression to cirrhosis in patients with chronic hepatitis B (CHB).

- PublicationMetadata onlySubclinical immune reactions to viral infections may correlate with child and adolescent diagnosis of attention-deficit/hyperactivity disorder: a preliminary study from Turkey(2014-01-01T00:00:00Z) Bekdas, Mervan; Tufan, Ali Evren; Hakyemez, Ismail Necati; Tas, Tekin; Altunhan, Huseyin; Demircioglu, Fatih; Kismet, Erol; HAKYEMEZ, İSMAİL NECATİBackground: Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neuro-developmental disorders of childhood and adolescence. Studies focusing on the relationship of infectious agents and ADHD are scarce. It is also known that cerebellar injury may lead to hyperactive behavior. This study aimed to evaluate the relationship between viral agents of cerebellitis and the diagnosis of ADHD.
- PublicationMetadata onlyRed Cell Volume Distribution Width to Platelet Ratio is an Important Predictor of Liver Fibrosis and Cirrhosis in Chronic Hepatitis B(2016-08-01) Hakyemez, Ismail Necati; BOLUKÇU, SİBEL; Durdu, BÜLENT; ASLAN, Turan; HAKYEMEZ, İSMAİL NECATİ; BOLUKÇU, SİBEL; DURDU, BÜLENTObjective: In recent years, a lot of non-invasive tests have been examined for estimating the severity of liver fibrosis in patients with chronic hepatitis B (CHB). We aimed to evaluate the role of simple and valuable platelet-derived indices in estimating the stage of fibrosis and cirrhosis in patients with CHB.
- PublicationMetadata onlyEvaluation of patients with Tularemia in Bolu province in northwestern Anatolia, Turkey(2014-03-01T00:00:00Z) Mengeloglu, Zafer; Duran, Arif; Hakyemez, Ismail Necati; Ocak, Tarik; Kucukbayrak, Abdulkadir; KARADAG, Mustafa; Tas, Tekin; Akdeniz, Hayrettin; HAKYEMEZ, İSMAİL NECATİIntroduction: Tularemia is a zoonotic disease caused by Francisella tularensis. Here we present an epidemic occurring in Bolu province, located in northwestern Anatolia in Turkey, and some features of the cases.

F.; HAKYEMEZ, İSMAİL NECATİBackground: Crimean-Congo hemorrhagic fever (CCHF), which is associated with a high mortality rate in the Black Sea region of Turkey, has received increasing attention.
- PublicationMetadata onlyInfective endocarditis case due to streptococcus parasanguinis presented with spondylodiscitis(2016-01-01) Hakyemez, Ismail Necati; Durdu, BÜLENT; Okay, GÜLAY; GULTEPE, Bilge; Bolukcu, SİBEL; ASLAN, Turan; HAKYEMEZ, İSMAİL NECATİ; DURDU, BÜLENT; OKAY, GÜLAY; BOLUKÇU, SİBEL; SÜMBÜL, BİLGEStreptococcus parasanguinis is a natural member of oral flora. It is an opportunistic pathogen, and rarely cause systemic infections due to it-s low virulence. Subacute infective endocarditis may present with various clinical manifestations (eg., spondylodiscitis). A sixty-five years old male patient from Northern Iraq has referred to our emergency service with high fever, weight loss, back pain and inability to walk. The patient was a veterinarian. He was operated three years ago for colonic carcinoma and irradiated. In magnetic resonance imaging, spondylodiscitis was detected localized in lumbar 1-2 region. Transthorasic echocardiography demonstrated aortic valve vegetation. S. parasanguinis was identified in the blood cultures. In conclusion; all in all, it-s remarkable to isolate S. parasanguinis as a causal agent of infective endocarditis in a patient who is a veterinarian with history of colonic carcinoma presented with clinical manifestation of spondylodiscitis.

- PublicationOpen AccessMortality markers in nosocomial Klebsiella pneumoniae bloodstream infection(2016-10-28) Durdu, BÜLENT; Hakyemez, Ismail Necati; BOLUKÇU, SİBEL; OKAY, GÜLAY; ASLAN, Turan; DURDU, BÜLENT; HAKYEMEZ, İSMAİL NECATİ; BOLUKÇU, SİBEL; OKAY, GÜLAY; SÜMBÜL, BİLGEPurpose: Klebsiella pneumoniae is the most common endogen agent for nosocomial infections. In this study, mortality markers were investigated in patients with nosocomial K. pneumoniae blood stream infection (NKp BSI). Methods: The characteristics of patients >16 years who had NKp BSI diagnosis by daily active surveillance between January 2012 and January 2016 were retrospectively evaluated. Patients who died until 28th day of the clinical follow up and those who survived until this time were statistically compared in terms of various risk factors. Results: One hundred ninety patients were included into the study. Mortality rate was 47.9%, carbapenem resistance was 43.2%. Statistical analysis have shown that in presence of post-NKp BSI sepsis, septic shock, following in intensive care unit (ICU), meropenem resistance, kidney failure, NKp BSI secondary to pneumonia, use of invasive instruments such as central venous catheter (CVC), urinary catheter (UC) and mechanical ventilator (MV), colostomy, transfusion and hemodialysis mortality was significantly higher. In patients admitted into the hospital for neurological disorders, pancreaticobiliary tract (PBT) diseases and patients who have undergone endoscopic retrograde cholangiopancreatography (ERCP) and patients in whom NKp BSI secondary to PBT infection mortality rate was lower. Conclusions: Sepsis, septic shock, clinical conditions requiring ICU treatment and meropenem resistance increase mortality rates in NKp BSI significantly. Mortality was higher also in patients with NKp BSI secondary to pneumonia, in kidney failure and when invasive instruments were used. On the other hand, in patients who were admitted to the hospital for neurological disorders and PBT diseases mortality rate was lower.
