Prospective Clinical Follow-Up Results of Infective Endocarditis.

Objective: Infective endocarditis incidence has been rising in recent years, with high mortality. Risk factors such as underlying heart diseases, chronic diseases, healthcare-associated infections, advanced age, and intravenous (IV) drug use have gained importance in the incidence, the treatment approach, and the disease course. The aim of this study is to contribute to Türkiye's data on infective endocarditis epidemiology and risk factors. Materials and Methods: This study examined risk factors, diagnostic and treatment approaches, and prognosis of infective endocarditis cases at Pamukkale University Faculty of Medicine Hospital. It was carried out prospectively for 28 months. Results: During this period, 67 endocarditis cases were detected in 65 patients. Among cardiac diseases, the rate of congenital heart diseases (41%), degenerative heart diseases (37%), and acute rheumatic fever (ARF) related valvular heart disease (31%) were found to be high. Hospitalization in the last six months (53.7%), history of cardiac surgery (41.8%), use of IV catheters (22.4%), hemodialysis (14.9%) and IV drug use (7.5%) were also determined. Staphylococci, streptococci, and enterococci were the primary agents. The most used empirical treatments were ampicillin, ampicillin-sulbactam, and gentamicin. Natural valve endocarditis was most determined. Surgical treatment was applied in 56.7% of endocarditis cases. Septic embolism and cardiac failure were the most common complications. Conclusion: This study's findings regarding the epidemiology and prognosis of infective endocarditis pointed out that it is still a disease with a high mortality rate.

Comparing TIMI, HEART, and GRACE Risk Scores to Predict Angiographic Severity of Coronary Artery Disease and 30-Day Major Adverse Cardiac Events in Emergency Department Patients with NSTEACS.

BACKGROUND: Acute coronary syndromes (ACS) are hard to diagnose because their clinical presentation is broad. Current guidelines suggest early clinical risk stratification to the optimal site of care. The aim of this study was to investigate the ability of Thrombolysis in Myocardial Infarction (TIMI); History, Electrocardiogram, Age, Risk Factors, Troponin (HEART); and Global Registry of Acute Coronary Events (GRACE) risk scores to predict the development of major adverse cardiac events (MACE) and the angiographic severity of coronary artery disease (CAD) in patients diagnosed with non-ST-segment elevation acute coronary syndrome (NSTEACS) in the emergency department (ED). In addition, independent variables associated with the development of MACE were also examined. METHODS: This study is a prospective, observational, single-center study. All patients over 18 years of age who were planned to be hospitalized for pre-diagnosed NSTEACS (NSTEMI + UAP) were included in the study consecutively. Patients' demographic information and all variables necessary for calculating risk scores (TIMI, HEART, and GRACE) were recorded. Two experienced cardiologists evaluated all coronary angiograms and calculated the Gensini score. RESULTS: The median age was 60 (IQR: 18) years, and 220 (61.6%) were male of the 357 patients included in the study. In this study, 91 MACE (52 percutaneous coronary interventions [PCI], 28 coronary artery bypass graft [CABG], three cerebrovascular disease [CVD], and eight deaths) occurred. The 30-day MACE rate was 25.5%. The low-risk group constituted 40.0%, 1.4%, and 68.0% of the population, respectively, in TIMI, HEART, and GRACE scores. Multiple logistic regression models for predicting MACE, age (P = .005), mean arterial pressure (MAP; P = .015), and High-Sensitive Troponin I (P = .004) were statistically significant. CONCLUSION: The ability of the GRACE, HEART, and TIMI risk scores to predict severe CAD in patients with NSTEACS is similar. In patients with NSTEACS, the HEART and GRACE risk scores can better predict the development of MACE than the TIMI risk score. When low-risk groups are evaluated according to the three risk scores, the HEART score is more reliable to exclude the diagnosis of NSTEACS.

Four Human Mpox Cases from Turkey.

Human mpox (formerly monkeypox) disease has recently been reported in a number of European countries among individuals with no history of international travel or animal contact, causing global epidemic concerns. We describe the demographic, clinical characteristics, and laboratory data of four male patients with mpox disease, three of whom were human immunodeficiency virus (HIV)-positive, and one who was HIV-negative but had type 1 diabetes mellitus and a recent history of urological surgery. The HIV-negative patient attracted interest because he had no history of suspected sexual contact; however, he used shared bathrooms and towels at work, which could explain the potential transmission route. The remaining three male patients engaged in sexual activity with men recently. All four patients had prodromal symptoms such as short-term fever, myalgia, or fatigue, followed by a vesicular-pustular rash that began in the genital area, and two also had lesions on other parts of their bodies. Mpox is not generally considered in the differential diagnosis intitally because it is rare in Turkey; however, the diagnosis should be considered in patients with pustular umbilicated lesions and a history of risky sexual behavior.

Mortality-associated factors of candidemia: a multi-center prospective cohort in Turkey.

Candidemia may present as severe and life-threatening infections and is associated with a high mortality rate. This study aimed to evaluate the risk factors associated with 30-day mortality in patients with candidemia. A multi-center prospective observational study was conducted in seven university hospitals in six provinces in the western part of Turkey. Patient data were collected with a structured form between January 2018 and April 2019. In total, 425 episodes of candidemia were observed during the study period. Two hundred forty-one patients died within 30 days, and the 30-day crude mortality rate was 56.7%. Multivariable analysis found that SOFA score (OR: 1.28, CI: 1.154-1.420, p < 0.001), parenteral nutrition (OR: 3.9, CI: 1.752-8.810, p = 0.001), previous antibacterial treatment (OR: 9.32, CI: 1.634-53.744, p = 0.012), newly developed renal failure after candidemia (OR: 2.7, CI: 1.079-6.761, p = 0.034), and newly developed thrombocytopenia after candidemia (OR: 2.6, CI: 1. 057-6.439, p = 0.038) were significantly associated with 30-day mortality. Central venous catheter removal was the only factor protective against mortality (OR: 0.34, CI:0.147-0.768, p = 0.010) in multivariable analysis. Candidemia mortality is high in patients with high SOFA scores, those receiving TPN therapy, and those who previously received antibacterial therapy. Renal failure and thrombocytopenia developing after candidemia should be followed carefully in patients. Antifungal therapy and removing the central venous catheter are essential in the management of candidemia.

An outbreak of tularemia in southwestern Turkey.

INTRODUCTION: Tularemia has reemerged and spread throughout Turkey, and the number of cases has increased. In this study, we report on a waterborne outbreak of tularemia in the spring of 2013 in a region which was previously disease-free, and we investigated the reasons for the outbreak. METHODOLOGY: The index case, a 17-year-old male, was diagnosed with oropharyngeal tularemia. An outbreak investigation was initiated after receiving information from other patients with similar symptoms from the same village along with Balkica, Tavas, and Denizli. An epidemiological and environmental investigation was conducted. Tonsil swab specimens/lymph node aspirates collected from patients, and water samples collected from unchlorinated drinking water sources, were cultured. Additionally, a real-time polymerase chain reaction (RT-PCR) was performed on these samples. Serum samples from patients were analyzed for antibody response. RESULTS: A total of 7 patients were found in this outbreak investigation. The attack rate was found to be 1% among the people of the village and 25% among patients' family members. The drinking-water system was contaminated with F. tularensis during this outbreak. CONCLUSIONS: Lack of appropriate water infrastructure and sanitation was the primary reason for this tularemia outbreak in Turkey. Improving the water source infrastructure and sanitation should be the primary approach to preventing tularemia outbreaks.

A short course of antimicrobial therapy for asymptomatic bacteriuria is safe and effective before urologic procedures.

INTRODUCTION: In the presence of asymptomatic bacteriuria (ASB) before the urological procedure, the duration of antimicrobial treatment is controversial. This study aims to evaluate whether a short course of antimicrobial therapy is safe and effective in cases with ASB before urological procedures. METHODOLOGY: We retrospectively reviewed adult patients who had ASB before undergoing several urological procedures between 2011 and 2019. The patients received a single dose of an appropriate parenteral antibiotic, determined by antimicrobial sensitivity testing, 30 to 60 minutes before the urological procedure. If a urinary catheter was placed post-procedure, a second dose was given. RESULTS: A total of 293 patients who had ASB before undergoing several urological procedures were included in the study. The total number of procedures was 328. Female/male ratio was 92 (31.4%)/201 (68.6%). The mean age was 63.7 ± 14.9 years. The most common isolated microorganisms were Escherichia coli (155 [47%]), Klebsiella pneumoniae (38 [11.6%]), and Pseudomonas aeruginosa (28 [8.5%]). The most common antimicrobial used was ertapenem. A second dose antimicrobial was given for 290 procedures due to a urinary catheter after a urological procedure. The mean hospitalization time was 3.97 ± 3.42 days. None of the patients developed infectious complications. CONCLUSIONS: This study has demonstrated that a single dose of parenteral antimicrobial drug administered 30-60 minutes before the urologic procedures and a second dose in the presence of a post-procedure catheter, was adequate to prevent post-procedure septicemia and urinary tract infection.

Risk factors for community-onset urinary tract infections caused by extended-spectrum ß-lactamase-producing Escherichia coli

Background/aim: Community-onset urinary tract infections(UTIs) caused by extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli have increased in many parts of the world. This study aimed to determine the prevalence and risk factors for community-onset UTI caused by ESBL-producing E. coli. Materials and methods: This prospective cohort study was conducted between January 2012 and March 2014 in cases of community-onset UTI caused by E. coli. Patients with UTI due to ESBL-producing E. coli and patients with UTI due to non-ESBL-producing E. coliwere compared to identify risk factors for ESBL-producing E. coli in the community. Results: A total of 305 patients (116 males [46.4%]; mean age: 57.76 ± 18.06 years) were included in the study. Among these patients, 154 (50.5%) were infected with ESBL-producing E. coli. In multivariate analysis, the healthcare-associated UTI (odds ratio [OR]: 1.80; 95% confidence interval [CI]: 1.02­3.18; P = 0.041), upper urinary tract infection (OR: 3.05; 95% CI: 1.76­5.29; P < 0.0001), use of antibiotics in the preceding 6 months (OR: 2.28; 95% CI: 1.21­4.30; P = 0.011), and having two or more risk factors (OR: 4.03; 95% CI: 1.73­9.35; P = 0.001) were the significant factors associated with increased risk of community-onset UTIs due to ESBL-producing E. coli. Conclusion: The increasing prevalence ofESBL-producing E. coli makes it difficult to decide the empirical therapy in UTIs, especially in patients with two or more of the risk factors. A better understanding of the epidemiology and risk factors associated with community-onset UTIs due to ESBL-producing E. coli may have significant implications in decision-making for empirical antimicrobial treatment.

[Isolation of Cryptococcus neoformans from a chesnut tree (Castanea sativa), Denizli, Turkey]. / Denizli bölgesinde kestane (Castanea sativa) agacindan Cryptococcus neoformans izolasyonu.

Cryptococcus neoformans is a basidiomycetous encapsulated yeast that can cause life-threatening infections in immunosuppressed humans and animals. C.neoformans/Cryptococcus gattii infections are considered to be acquired via inhalation of aerosolized particles from the environment. Avian guano, decaying tree hollows and soil are known as environmental niches. In recent years, colonization of the woody structures of different trees such as Eucalyptus camaldulensis, Tamarix hispida, Platanus orientalis and Punica granatum has been reported in the environmental study of the western Anatolian region. Based on the results of previous studies, our country may have intensive Cryptococcus colonization niches in the western regions. The aim of this study was to investigate the presence of the colonization of C.neoformans niche in chestnut (Castanea spp.) trees on higher altitudes. In the study, the colonization of C.neoformans was screened on chestnut trees (Castanea spp.) in Aydin-Ödemis-Denizli geographical area. This area consists of mountainous terrain between the fertile plain formed by two major rivers.This region is one of the widespreading areas of chestnut farming in Anatolia. Two hundred and fourteen chestnut trees that had deep fissures or trunk hollows were screened during mid-summer 2017. A swabbing technique was used, and all samples were cultured on Staib agar medium containing biphenyl and antibiotics. Cultures were checked for ten days for suspicious brown colonies. Suspicious yeast colonies were tested for the identification of pathogenic Cryptococcus by conventional methods and canavanine-glycine-bromothymol agar reactions. ITS 1-4 primers were used for strain PCR tests. We determined the mating type and serotypes by PCR analysis of the STE20 genes using STE20 (Aa), STE20 (Aα), STE20 (Da), and STE20 (Dα) primers. V8 agar medium was used for mating cultivation. Only one (0.47%) strain of C.neoformans was isolated from 214 screened trees. This strain was confirmed by ITS 1-4 sequencing. The serotype A MATα mating type was observed. Basidium, basidiospores and clamp connections in hyphal structure were noted with MATα mating on V8 agar medium. In this study, the first C.neoformans isolate from a chestnut tree (Castanea sativa) was determined from Denizli region. Further studies of distribution of human pathogenic Cryptococcus will be helpful to determine the risk areas for the living organisms in our region.

THE THICKNESSES OF CHOROID, MACULAR SEGMENTS, PERIPAPILLARY RETINAL NERVE FIBER LAYER, AND RETINAL VASCULAR CALIBER IN HIV-1-INFECTED PATIENTS WITHOUT INFECTIOUS RETINITIS.

PURPOSE: To evaluate choroidal, macular, peripapillary retinal nerve fiber layer (RNFL) thicknesses and retinal vascular caliber alterations in HIV-1-infected patients without opportunistic infections. METHODS: This cross-sectional study included 45 HIV-1-infected patients and 47 healthy subjects. Spectral domain optical coherence tomography was used for assessment of choroidal, macular, peripapillary RNFL thicknesses and retinal vascular caliber alterations. RESULTS: The mean CD4 count was 426 ± 226 cells per milliliter and the mean HIV-1 RNA level was 1.8 × 10 ± 3.6 × 10 copies/mL in HIV-infected group. Central inner plexiform, superior photoreceptor, superior and nasal retinal pigment epithelium layers were thinner in HIV-infected patients compared with control subjects (P < 0.05). The differences in sectoral retinal thicknesses lost their significance after Bonferroni correction (P < 0.01). The average thickness of pericentral retina within 3 mm was thinner in the photoreceptor layer in HIV-infected patients compared with control subjects (P = 0.033). The differences in peripapillary RNFL thickness, choroidal thickness, and retinal vascular caliber were not significant between the groups. Choroidal thickness and pericentral outer plexiform were thinner, whereas peripapillary RNFL was thicker in newly diagnosed cases (16 patients) compared with patients having treatment for at least 4 months or longer (27 patients, P < 0.05, Mann-Whitney U test). HIV-1 RNA showed negative correlation with choroidal thickness (r = -0.435, P = 0.003) and positive correlation with peripapillary RNFL in central (r = 0.323, P = 0.032) and superonasal (r = 0.369, P = 0.014) sectors. CONCLUSION: Choroidal thickness was thinner in newly diagnosed patients compared with patients on treatment. Viral load showed negative correlation with choroidal thickness. Retinal segmental alterations occurred in HIV-infected patients compared with control subjects.

Daptomycin vs. glycopeptides in the treatment of febrile neutropenia: results of the Izmir matched cohort study.

PURPOSE: In this multicentre, retrospective, matched cohort study we aimed to evaluate the outcomes of neutropenic fever cases that were treated with daptomycin or a glycopeptide (vancomycin or teicoplanin). METHODS: Data and outcomes of adult (aged > 18-years old) patients with neutropenic fever [(1) without clinical and radiological evidence of pneumonia, (2) who were treated with daptomycin or a glycopeptide (teicoplanin or vancomycin) for any reason and for at least 72 h] were extracted from the hospital databases. Matching was performed with all of the three following criteria: (1) underlying disease, (2) reason for starting daptomycin or glycopeptide (microbiologic evidence vs. microbiologic evidence, clinical infection vs. clinical infection and empirical therapy vs. empirical therapy) and (3) neutropenic status. RESULTS: Overall 128 patients [(69/123) (56.1%) in the daptomycin cohort (D) and 59/123 (48%) in the glycopeptide cohort (G)] had a resolution of fever at the end of 72 h antibiotic treatment (p = 0.25). There was no significant difference in cured, improved and (cured + improved) rates between (D) and (G) cohorts as well as fever of unknown origin cases or microbiologically confirmed infections or clinically defined infections subgroups (p > 0.05). There was also no significant difference (p > 0.05), in terms of persistent response in the (D) versus (G) cohorts, CONCLUSIONS: These findings suggest that although not better, daptomycin efficacy is comparable to vancomycin if used as empiric therapy in the treatment of adult febrile neutropenia. We conclude that daptomycin may be used at least as a salvage therapy alternative to glycopeptides in the treatment of adult febrile neutropenia cases. A large, randomized-controlled trial may further consolidate the evidence related to this question.

Corneal and Anterior Chamber Morphology in Human Immunodeficiency Virus-1-Infected Patients Without Opportunistic Infections.

OBJECTIVES: To evaluate corneal and anterior chamber morphology as measured by Pentacam HR in human immunodeficiency virus (HIV)-infected patients without opportunistic infections and to search for signs of accelerated aging. METHODS: This prospective study included 41 eyes of 41 HIV-1-infected patients (study group) and 50 eyes of 50 healthy subjects (control group). Specular microscope and Pentacam HR were used for corneal and anterior chamber morphology evaluation. Corneal endothelial cell density (CECD), hexagonal cell ratio, coefficient of variation, corneal thickness, density and volume, maximum keratometry, anterior chamber volume (ACV), and anterior chamber depth (ACD) measurements were recorded for analysis. RESULTS: The mean CD4 count was 428.3±231.9 (36-950) cells/mL, and the time since diagnosis was 27.5±34.1 months in the study group. The difference in anterior segment parameters was not significantly different between the study and the control groups (P>0.05). Age significantly correlated with CECD (r=-0.436, P=0.004), ACV (r=-0.570, P<0.001), ACD (r=-0.471, P=0.002), and corneal density (r=0.424, P=0.006) in the study group, whereas it did not show a significant correlation with any ocular parameters in the control group (Pearson correlation). CONCLUSION: Corneal density, CECD, ACV, and ACD showed significant correlation with age in HIV-1-infected patients. Further studies are needed to show whether ocular parameters may serve as useful tools to monitor HIV-related accelerated aging.

Spondylodiscitis: a common complication of brucellosis.

INTRODUCTION: Brucellar spondylodiscitis is a frequent and serious complication of brucellosis. The aim of this study is to describe the brucellosis patients with spondylodiscitis and the predictive factors related to spondylodiscitis in brucellosis. METHODOLOGY: Laboratory-confirmed brucellosis patients from a low- to medium-endemic region were enrolled in the study and distributed into two groups. Group I consisted of patients with spondylodiscitis and Group II patients had no complications. Both groups were compared for predictive factors of spondylodiscitis. RESULTS: A total of 219 patients with active brucellosis were included in the study. We determined at least one complication in 91 (41.6%) patients. The most frequent complication was spondylodiscitis [n = 59 patients (26.9 %)]. In univariate analysis, age, time from symptom onset to diagnosis, presence of low back pain, increased levels of erythrocyte sedimentation rate, and alkaline phosphatases were the most significant predictive factors for spondylodiscitis among brucellosis cases. Presence of headache and thrombocytopenia were less frequent in patients with spondylodiscitis when compared to patients without complications (p = 0.024, p = 0.006 respectively). In multivariate analysis, old age (odds ratio [OR] 1,063; 95% confidence interval [CI] 1.026-1.101; p < 0.001), prolonged time between symptoms onset before diagnosis (OR 1.008; 95% CI 1.001-1.016; p = 0.031), and presence of low back pain (OR 12.886; 95% CI 3.978-41.739; p < 0.001) were indepedently associated with an increased risk of spondylodiscitis. CONCLUSIONS: Spondylodiscitis is the most frequent complication of systemic brucellosis. Patients with low back pain, older age, and longer duration of symptoms should be considered as candidates of potential spondylodiscitis in brucellosis.

The first report of Brucella suis biovar 1 isolation in human in Turkey.

BACKGROUND: Brucella melitensis and B. abortus are the species generally isolated from human samples in Turkey. Several studies have also demonstrated the presence of antibodies against B. canis. CASE REPORT AND STUDY: Brucella spp. was isolated from blood culture from a 35-year-old male with clinical signs and symptoms of acute meningitis, including fever lasting for 1 week. Multiplex PCR demonstrated B. suis, and biochemical features indicated biovar 1. CONCLUSIONS: This report is the first emphasizing that B. suis should be considered among the causes of brucellosis in Turkey.

Acute Brucella melitensis M16 infection model in mice treated with tumor necrosis factor-alpha inhibitors.

INTRODUCTION: There is limited data in the literature about brucellosis related to an intracellular pathogen and anti-tumor necrosis factor alpha (anti-TNFα) medication. The aim of this study was to evaluate acute Brucella infections in mice receiving anti-TNFα drug treatment. METHODOLOGY: Anti-TNFα drugs were injected in mice on the first and fifth days of the study, after which the mice were infected with B. melitensis M16 strain. Mice were sacrificed on the fourteenth day after infection. Bacterial loads in the liver and spleen were defined, and histopathological changes were evaluated. RESULTS: Neither the liver nor the spleen showed an increased bacterial load in all anti-TNFα drug groups when compared to a non-treated, infected group. The most significant histopathological findings were neutrophil infiltrations in the red pulp of the spleen and apoptotic cells with hepatocellular pleomorphism in the liver. There was no significant difference among the groups in terms of previously reported histopathological findings, such as extramedullary hematopoiesis and granuloma formation. CONCLUSIONS: There were no differences in hepatic and splenic bacterial load and granuloma formation, which indicate worsening of the acute Brucella infection in mice; in other words, anti-TNFα treatment did not exacerbate the acute Brucella spp. infection in mice.

Risk factors for occupational brucellosis among veterinary personnel in Turkey.

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4-11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4-16) years in the non-brucellosis group (p<0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55-5.28, p=0.001), being male (OR, 4.5; 95% CI, 1.05-18.84, p=0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002-1.02, p=0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16-9.3, p<0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection.

Pulmonary mucormycosis due to Lichtheimia ramosa in a patient with HIV infection.

Mucormycosis is increasingly common in patients with risk factors such as diabetes mellitus, neutropenia, and corticosteroid therapy. However, mucormycosis seems to be less common in patients with human immunodeficiency virus (HIV) infection compared to patients with other risk factors. Despite their lower virulence, Lichtheimia species should be regarded as emerging pathogens among Mucoralean fungi. We report a fatal case of pulmonary mucormycosis due to Lichtheimia ramosa in a 52-year-old man with an end-stage HIV infection. He had a cachectic appearance and his CD4 count was 8 cells/mm(3). The fungal infection was diagnosed based on a positive sputum culture with histopathologic confirmation. The fungus was resistant to caspofungin, anidulafungin, and voriconazole [minimum inhibitory concentration (MCI) >32 µg/ml], whereas the E test MIC values of itraconazole, posaconazole, and amphotericin B were 0.38, 0.38, and 0.5 µg/ml, respectively. Although intravenous drug use is the main risk factor for the development of mucormycosis in HIV-infected patients, it may also develop in patients with low CD4 count, opportunistic infections and/or additional diseases, such as Kaposi's sarcoma or severe immunodeficiency, as in our case.

[Isolation of Scedosporium apiospermum (teleomorph: Pseudallescheria apiosperma) from an acute myeloid leukemia patient]. / Bir akut miyeloid lösemi hastasindan Scedosporium apiospermum (teleomorf: Pseudallescheria apiosperma) izolasyonu.

Scedosporium apiospermum is an emerging opportunistic pathogen that may lead to life-threatening infections especially in immunosuppressive individuals. In this report, S.apiospermum infection in a 62 year old male patient with acute myeloid leukemia was presented. During remission-induction chemotherapy, piperacillin-tazobactam therapy was started for febrile neutropenia. Since fever had continued, treatment was switched to imipenem and also amphotericin B deoxycholate was added to the treatment protocol. Because of allergic reaction to amphotericin B, caspofungin was started at the fifth day of neutropenic fever. Following imaging studies with high resolution computerized thorasic tomography, antifungal therapy was changed to voriconazole due to findings suggestive of invasive aspergillosis. Since galactomannan antigen was found negative at the first day of voriconazole therapy, bronchoalveolar lavage material from apical segment of the left lower lobe was cultured onto various microbiologic media. S.apiospermum (Teleomorph: Pseudallescheria apiosperma) was isolated on the fourth day of cultivation. According to CLSI M38-A2 microdilution procedure, minimum inhibitory concentrations (MIC) of voriconazole, caspofungin, amphotericin B and posaconazole were found as 0.06, 2, 8 and 4 µg/ml, respectively. Since neutropenia was resolved, the patient was discharged with continued voriconazole therapy. It was concluded that antifungal susceptibility tests should be performed for Scedosporium species and the results should be compared to the clinical response. The determination of MIC breakpoints may provide useful information for the recommendation and use of optimal choices for the treatment of Scedosporium infections.

H1N1 infection in Pregnancy: clinical course in two women.

Pregnant women are one of the major risk groups for disease related morbidity and mortality from influenza A (H1N1, swine flu) pandemic. Healthy pregnant women are supposed to have 4 to 5 fold increased rate of serious illness and hospitalization compared to non-pregnant subjects. Herein, the clinical course of novel influenza A (H1N1) infection in two pregnant women was presented. One woman expired due to delay in treatment, while the other one was discharged on day six after prompt treatment. We would like to emphasize that obstetricians should be aware of the clinical and radiological manifestations of influenza A for prompt diagnosis and treatment. Obstetricians also should prepare themselves to provide adequate care for pregnancy related complications encountered by pregnant women with H1N1 infection.
