RESUMEN
BACKGROUND: There is limited evidence on the modification or stopping of antiretroviral therapy (ART) regimens, including novel antiretroviral drugs. The aim of this study was to evaluate the discontinuation of first ART before and after the availability of better tolerated and less complex regimens by comparing the frequency, reasons and associations with patient characteristics. METHODS: A total of 3019 ART-naive patients registered in the HIV-TR cohort who started ART between Jan 2011 and Feb 2017 were studied. Only the first modification within the first year of treatment for each patient was included in the analyses. Reasons were classified as listed in the coded form in the web-based database. Cumulative incidences were analysed using competing risk function and factors associated with discontinuation of the ART regimen were examined using Cox proportional hazards models and Fine-Gray competing risk regression models. RESULTS: The initial ART regimen was discontinued in 351 out of 3019 eligible patients (11.6%) within the first year. The main reason for discontinuation was intolerance/toxicity (45.0%), followed by treatment simplification (9.7%), patient willingness (7.4%), poor compliance (7.1%), prevention of future toxicities (6.0%), virologic failure (5.4%), and provider preference (5.4%). Non-nucleoside reverse transcriptase inhibitor (NNRTI)-based (aHR = 4.4, [95% CI 3.0-6.4]; p < 0.0001) or protease inhibitor (PI)-based regimens (aHR = 4.3, [95% CI 3.1-6.0]; p < 0.0001) relative to integrase strand transfer inhibitor (InSTI)-based regimens were significantly associated with ART discontinuation. ART initiated at a later period (2015-Feb 2017) (aHR = 0.6, [95% CI 0.4-0.9]; p < 0.0001) was less likely to be discontinued. A lower rate of treatment discontinuation for intolerance/toxicity was observed with InSTI-based regimens (2.0%) than with NNRTI- (6.6%) and PI-based regimens (7.5%) (p < 0.001). The percentage of patients who achieved HIV RNA < 200 copies/mL within 12 months of ART initiation was 91% in the ART discontinued group vs. 94% in the continued group (p > 0.05). CONCLUSION: ART discontinuation due to intolerance/toxicity and virologic failure decreased over time. InSTI-based regimens were less likely to be discontinued than PI- and NNRTI-based ART.

PURPOSE: To investigate the long-term effect of HIV infection on the ganglion cell-inner plexiform layer and retinal capillary network. METHODS: This prospective, cross-sectional case-control study included 45 HIV-infected patients and 45 healthy individuals. Optical coherence tomography angiography (OCTA) was used for the assessment of macular, peripapillary retinal nerve fiber layer (RNFL) thicknesses, ganglion cell-inner plexiform layer, vessel density, perfusion density, and foveal avascular zone. RESULTS: The mean disease duration was 7.3 ± 1.9 years (range, 5-12 years) in the HIV group. The mean CD4 count (nadir) for all the patients was 147.09 ± 122 cells/mm3 and the mean RNA was 173.6 ± 913.8 copies/ml. No statistically significant difference was determined between the groups in respect of the average and foveal MT (p = 0.05). A significant difference was found between the two groups in respect of the mean VD and PD parameters (p < 0.05). Peripapillary PD was significantly decreased in the HIV group. There was a significant difference between the average and superior and inferior half-region of GC-IPL values. Using Pearson's correlation analysis, no significant correlation was determined between the duration of HIV infection and mean GC-IPL, MT and VD, and PD values (r - 0.223, p 0.141; r - 0.223, p 0.141; r - 0.169, p 0.268; r - 0.105, p 0.491; r - 0.095, p 0.535 respectively). CONCLUSIONS: The results of this study provide evidence of microvascular and neuroretinal loss in individuals with well-suppressed HIV infection, compared with healthy control subjects. OCTA is an important test for the screening of retinal microvascular changes over time in HIV-infected cases.

Neurosyphilis (NS) has different clinical manifestations and can appear during any stage of syphilis. We aimed to identify the factors affecting poor outcome in NS patients. Patients with positive cerebrospinal fluid Venereal Disease Research Laboratory test, and positive serological serum treponemal or nontreponemal tests were classified as definite NS. The data of 141 patients with definite NS were submitted from 22 referral centers. Asymptomatic NS, syphilitic meningitis, meningovascular syphilis, tabes dorsalis, general paresis, and taboparesis were detected in 22 (15.6%), 67 (47.5%), 13 (9.2%), 10 (7%), 13 (9.2%), and 16 patients (11.3%), respectively. The number of HIV-positive patients was 43 (30.4%). The most common symptoms were headache (n = 55, 39%), fatigue (n = 52, 36.8%), and altered consciousness (50, 35.4%). Tabetic symptoms were detected in 28 (19.8%), paretic symptoms in 32 (22.6%), and vascular symptoms in 39 patients (27.6%). Eye involvement was detected in 19 of 80 patients (23.7%) who underwent eye examination and ear involvement was detected in eight of 25 patients (32%) who underwent ear examination. Crystallized penicillin was used in 109 (77.3%), procaine penicillin in seven (4.9%), ceftriaxone in 31 (21.9%), and doxycycline in five patients (3.5%). According to multivariate regression analysis, while headache was a protective factor in NS patients, double vision was significantly associated to poor outcome. We concluded that double vision indicated unfavorable outcome among NS patients. A high clinical suspicion is needed for the diagnosis NS. As determined in our study, the presence of headache in syphilitic patients can help in early diagnosis of central nervous system disease.

Visceral leishmaniasis (VL, kala-azar) is a zoonotic infection caused by Leishmania species which are transmitted to humans by the bites of infected female phlebotomine sandflies. Leishmania infantum is the responsible species of VL in Aegean, Mediterranean, and Central Anatolia regions of Turkey mainly observed sporadically in pediatric age groups. The aim of this study was to evaluate the clinical and laboratory findings of adult patients with VL who were admitted to our hospital. A total of 10 patients (3 female, 7 male; age range: 18-67 years, mean age: 39.3 ± 16.51) followed in the infectious diseases clinic of the hospital between 2000 and 2013 were evaluated retrospectively. The diagnosis of VL was based on the presence of appropriate clinical and physical examination, as well as biochemical findings, positive serological test results (indirect fluorescent antibody test, and rK39 rapid antigen test) and/or detection of amastigote forms of parasite in the bone marrow aspiration samples. Of the cases three were diagnosed with both bone marrow and serology positivity, five with bone marrow positivity and one of each only with liver biopsy and positive serology result. Time interval from onset of the symptoms until the establishment of the specific clinical diagnosis was ranged from 2 to 12 weeks. The most frequent initial symptoms were fever, fatigue and abdominal distension. None of the patients had immunosupressive conditions such as HIV infection, corticosteroid use, immunosupressive treatment, or transplantation. All the patients were from Aegean region and six were living in rural areas. In all cases, hepatosplenomegaly, increased erythrocyte sedimentation rate, albumin/globulin ratio inversion, anemia, leukopenia and among nine cases trombocytopenia were detected. In one case acute renal failure has been developed before treatment and the patient was admitted to dialysis program. Bacterial superinfection occurred in two cases. Patients were treated with either meglumine antimonate (Glucantime(®), 20 mg/kg/day, intramuscularly for 28 days) or liposomal amphotericin B (3 mg/kg/day, intravenously for the first 5 days, then on 14(th) and 21(st) days) according to the availability of drugs. During one year follow-up period all of the patients improved and no recurrence was seen in any patient. In conclusion, among adult patients with fever uncontrolled within 2-week course of ampiric antibiotic treatment without any infectious focus or malignancy, VL should also be considered.

A major proportion of the global HIV infections is caused by group M of HIV-1 genotype and to date approximately nine subtypes (A, B, C, D, F, G, H, J, K) and 50 circulating recombinant forms (CRFs) have been recognized. Recombinants between different HIV-1 group M subtypes are designated as CRF. The extension 'cpx', for complex, is given if the CRF consists of contributions from three or more different subtypes but the composition of the subtype is not given. The objective of this study was to present, for the first time an HIV-1 positive married couple infected with CRF06_cpx subtype in Izmir, Turkey. A 39-year-old male patient who admitted to hospital with the complaints of oral candidiasis and zona, was found to be anti-HIV positive. CD4+ T lymphocyte count was 21 cells/mm3 and plasma HIV-1 RNA level was 56.380 copies/ml. He reported unprotected heterosexual contact with multiple partners including African women during his stay in Saudi Arabia between 1996 and 2002. After his diagnosis, his 37-year-old wife was screened for HIV infection and she was also found anti-HIV positive, with CD4+ T cell count of 122 cells/mm3. However, her results of basal plasma HIV-1 RNA could not be obtained because of an internal control error. HIV-1 strains were analysed for subtyping, recombination and drug resistance mutations with pol gene region sequencing. HIV-1 sequences were subtyped as CRF06_cpx after phylogenetic analysis using neighbor-joining method. According to the recombination analysis, HIV-1 pol gene regions consisted of group M subtype G, A, D, and B in the male patient and G K, A, F, and D in the female patient. While L10I + L33F mutation associated with protease inhibitor (PI) resistance was detected in both of the patients, K219N mutation associated with nucleoside reverse transcriptase inhibitor (NRTI) resistance was detected only in the male patient. In conclusion, HIV-1 molecular epidemiology studies are important tools for tracking transmission patterns and the spread of CRF. Global monitoring of CRF subtypes is also important to supply data for HIV vaccine development studies. On the other hand, the detection of HIV-1 primary resistance mutations in antiretroviral naive patients suggested that the resistance testing should be an integral part of the management of HIV infection.

INTRODUCTION: In this study, we aimed to compare the effectiveness of various chelating agents, ethilenediaminetetraacetic acid (EDTA), citric acid (CA), and etidronic acid (HEDP) mixed in two different forms, in removing the smear layer and promoting the penetration of an endodontic sealer into the dentinal tubules of extracted single-rooted teeth. METHODS: The study used 75 teeth divided into five groups: 17% EDTA, 10% CA, 9% HEDP + NaOCl, 9% HEDP + distilled water (DW), and a control (DW) group. Scanning electron microscopy was used to assess smear layer removal and confocal laser microscopy was used to evaluate tubular sealer penetration at different depths from the apical tip. RESULTS: Sealer penetration was highest with 17% EDTA and 10% CA as compared with the other agents (p<0.001). At the cervical third, the sealer penetration for EDTA, HEDP + NaOCl, and HEDP + DW groups were significantly different than those in DW (p = 0.020). For the middle third, EDTA, CA, and HEDP + NaOCl groups were significantly higher than those of the DW group (p<0.001). Cervical-level values were significantly higher than apical-level values for HEDP + NaOCl, HEDP + DW, and DW (p<0.001). Smear layer removal was lower with 9% HEDP + DW than with 17% EDTA and 10% CA at all depths (p<0.001). A significancy in smear layer removal was observed between 10% CA and control (p = 0.015) in middle depth. CONCLUSION: Within the limitations of this study, highest values were seen in EDTA and CA in terms of sealer penetration and smear layer removal. In the light of these findings, the use of strong chelating agents highlights better clinical efficiency than dual-rinse or single HEDP irrigation.

Brucellosis is an important cause of spondylodiscitis in endemic areas. Brucellar spondylodiscitis is a serious complication because of its association with abscess formation. Prospective studies comparing patients with and without abscesses are lacking. The objective of this study was to determine the frequency and demographic, clinical, laboratory, and radiological features of brucellar spondylodiscitis and to compare patients with and without abscesses regarding treatment and outcome. Out of 135 consecutive patients with brucellosis, 31 patients with spondylodiscitis were recruited for the study. Patients were grouped according to magnetic resonance imaging findings. The frequency of spondylodiscitis was 23.0 %. Sites of involvement were lumbar (58.1 %), lumbosacral (22.6 %), cervical (9.7 %), thoracolumbar (6.5 %), and thoracic (3.2 %). Abscesses occurred in 19 (61.3 %) patients and were associated with low hemoglobin levels. Medical treatment included a combination of streptomycin (for the first 3 weeks), doxycycline, and rifampin. The total duration of treatment was 12-39 (mean 17.0 ± 8.5 SD) weeks. By 12 weeks of treatment, evidence of clinical improvement (67 vs. 28 %) and radiological regression (92 vs. 50 %) was significantly greater in patients without abscesses. The duration of treatment was longer if an abscess was present. Two female patients with abscesses required surgical intervention. Both patients presented with high fever, neurologic deficit, and high Brucella standard tube agglutination test titers. Each patient should be evaluated individually, based on clinical findings, laboratory data, and radiological results, when undergoing treatment for brucellar spondylodiscitis. If abscesses are found, a longer course of treatment and even surgical intervention may be needed.

OBJECTIVES: This study aimed to analyze the antiretroviral drug resistance in antiretroviral treatment-naïve HIV-positive patients in the Aegean Region of Turkey from 2012 to 2019. METHODS: The study included 814 plasma samples from treatment-naïve HIV-positive patients. Drug resistance analysis was performed by Sanger sequencing (SS) between 2012-2017 and by next-generation sequencing sequencing (NGS) between 2018-2019. SS was used to analyze resistance mutations in the protease (PR) and reverse transcriptase (RT) gene regions using a ViroSeq HIV-1 Genotyping System. PCR products were analyzed with an ABI3500 GeneticAnalyzer (Applied Biosystems). The sequencing of the HIV genome in the PR, RT, and integrase gene regions was carried out using MiSeq NGS technology. Drug resistance mutations and subtypes were interpreted using the Stanford University HIV-1 drug resistance database. RESULTS: Transmitted drug resistance (TDR) mutation was detected in 34/814 (4.1 %) samples. Nonnucleoside reverse transcriptase inhibitor (NNRTI), nucleoside reverse transcriptase inhibitor (NRTI), and protease inhibitor (PI) mutations were identified in 1.4 % (n =12), 2.4 % (n =20), and 0.3 % (n = 3) of samples, respectively. The most common subtypes were B (53.1 %), A (10.9%), CRF29_BF (10.6%), and B + CRF02_AG (8,2%). The most common TDR mutations were E138A (3.4%), T215 revertants (1.7%), M41L (1.5%), and K103N (1.1%). CONCLUSION: Transmitted drug resistance rate in the Aegean Region is compatible with national and regional data. Routine surveillance of resistance mutations may guide the safe and correct selection of initial drug combinations for antiretroviral therapy. The identification of HIV-1 subtypes and recombinant forms in Turkey may contribute to international molecular epidemiological data.

The aims of this study were to evaluate the attitudes towards H1N1 vaccination and to determine the safety and side effects following 2009 pandemic influenza A (H1N1) vaccination. Pandemic influenza vaccine had been administered to the healthcare personnel in our research and training hospital in December 2009. The rate being vaccinated was established as 40% (800/2000). Four months following vaccination, the opinions about vaccination were asked to the healthcare workers, and also side effects were questioned to the vaccinated group. Two different questionnaires (for vaccinated and unvaccinated subjects) were delivered to the volunteers who agreed to participate in the study. Demographic features, reasons related to being vaccinated or not, were questioned. The vaccinated group was also questioned for the presence of chronic diseases, previous vaccinations (pandemic/seasonal influenza), local or systemic reactions that develop after vaccination. A total of 332 volunteers participated in the questionnaire. Of them 247 (74.4%) were vaccinated and 85 (25.6%) were unvaccinated. Male/female ratio of the participants was 1.2, and 55.7% of them were older than 30-year-old. Most of the participants (82.8%) were highly educated (high school and faculty-graduated). Vaccination rates were found statistically significant in advanced age group compared to young adults (p= 0.042); in male gender compared to females (p= 0.001) and in parents compared to subjects who didn't have children (p= 0.021). Vaccination rates were observed to be higher (57.5%) in non-medical staff (cleaning employers, administrative personnel, etc.) than the physicians (29.1%) and nurses (13.4%), and the rate was also high (54.7%) in personnel who worked in intensive care units, emergency department and administrative units than the personnel who worked in the clinics of internal medicine (22.3%) and surgery (23.1%) (p= 0.001). The most important causes of rejecting vaccination were being afraid of the side effects (69.4%) and not believing the effectiveness of the vaccine (56.4%). The leading causes of accepting vaccination were worries about infecting their family (60.3%) and being in a risk group (54.3%). After vaccination, local reactions (pain, swelling and redness at the vaccination site) were described in 43.3% and systemic reactions (weakness, fatigue, muscle aches, influenza-like symptoms, etc.) were described in 43.7% of the subjects. Severe side effects such as vasculitis, neuritis, encephalomyelitis, Guillian-Barre syndrome and anaphylactic reaction were not observed in any of the vaccinated cases. It was detected that worries about the safety of vaccine had negative impact for vaccination. Since no serious side effects were detected related to vaccination, it was concluded that the vaccine was safe. In spite of the scientific proofs, negative concerns about the safety of the vaccines can unfavorably affect the vaccination campaigns and can jeopardize efforts of influenza control. As a result, data collection systems about the safety and side effects of the vaccine all over the country and regular reports about these data may more efficiently guide vaccination programs in the future.

INTRODUCTION: The most prominent characteristic of adult attention deficit hyperactivity disorder (ADHD) is impulsive behavior and deficits in executive functions, which require long-term organization and discipline. This may have serious implications in terms of adherence to treatment among adults living with HIV (PLWH). This study aimed to determine the prevalence of ADHD among non-perinatally infected PLWH and its effect on adherence to antiretroviral treatment (ART) and scheduled appointments. METHODOLOGY: The PLWH admitted to our centers between January 2012 and February 2016 were invited to the study. ADHD diagnosis was made according to the novel criteria guided interviews. The first ART interruption for ≥ 6 days per month (≤ 80%) was defined as ''ART-event'' and the first non-attendance of any scheduled appointment was defined as ''appointment-event''. Kaplan-Meier plot with a Log-rank test was used for event-free adherence (EFA). RESULTS: Twenty-five patients out of 85 were diagnosed with ADHD (29.4 %) which was significantly higher than the highest percentage reported (7.3 %) for the general population (p < 0.0001). Both ART-event (p = 0.0002) and appointment-event (p = 0.02) were significantly higher among ADHD participants compared to those without. Additionally, both ART-EFA (p = 0.00014) and appointment-EFA (p = 0.023) were significantly shorter among ADHD participants compared to those without. CONCLUSION: ADHD is significantly higher in adult PLWH and people with ADHD had a significant tendency for non-adherence to ART and follow-up. Screening for ADHD as well as providing treatment when required would be beneficial to achieve and maintain virologic success.

BACKGROUND/AIM: The aim of this study was to determine the prevalence and associated factors of thrombocytopenia in human immunodeficiency virus (HIV)-infected patients. MATERIALS AND METHODS: A cross-sectional study was conducted in a tertiary care hospital in Izmir, Turkey. All HIV-infected patients admitted to the Department of Infectious Diseases and Clinical Microbiology between 2006 and 2011 were recruited. Patients with thrombocytopenia at any time point were defined as the case group and the remaining patients were defined as the control group. RESULTS: The frequency of thrombocytopenia was 35.8%. Thrombocytopenia was more frequent in patients with acquired immune deficiency syndrome (AIDS) than in patients without AIDS (P < 0.05) and in antiretroviral-naive patients than in patients on combination antiretroviral therapy (cART) or those who had ever used cART in the past (P < 0.05). Additionally, rates of tuberculosis infection, prophylactic use of trimethoprim-sulfamethoxazole (TMP/SMX), and being anti-HCV seropositive at any time point were higher in patients with thrombocytopenia than in the control group (P < 0.05), and the case group had lower CD4+ T lymphocytes at first admission (P < 0.05). CONCLUSION: The main finding was the clear association between thrombocytopenia and advanced and uncontrolled HIV infection. Tuberculosis and HCV coinfections were also identified as associated factors for thrombocytopenia.

Microdimensioned osteosynthesis using miniplates has been common practice in maxillofacial surgery. However, tooth injury during the application of the miniplates have been reported in few papers. In this case, a 32-yr-old female patient, whose two teeth were necrosed because of the perforation during screw insertion was presented. The reason of the perforations during the rigid internal fixation was the lack of radiographic assessment because of the pregnancy. Maxillary right first premolar and maxillary left canine were perforated and necrosed because of the screw insertion. The necrosed teeth were detected 1 yr after the rigid internal fixation. The root canals of nonvital teeth were filed using step-down approach. Cold lateral condensation of gutta-percha was used to fill the canals. Six-month recall visits were scheduled and there was no problem after 2-yr follow-up period.

HIV-1 replication is rapid and highly error-prone. Transmission of a drug-resistant HIV-1 strain is possible and occurs within the HIV-1-infected population. In this study, we aimed to determine the prevalence of transmitted drug resistance mutations (TDRMs) in 1,306 newly diagnosed untreated HIV-1-infected patients from 21 cities across six regions of Turkey between 2010 and 2015. TDRMs were identified according to the criteria provided by the World Health Organization's 2009 list of surveillance drug resistance mutations. The HIV-1 TDRM prevalence was 10.1% (133/1,306) in Turkey. Primary drug resistance mutations (K65R, M184V) and thymidine analogue-associated mutations (TAMs) were evaluated together as nucleos(t)ide reverse transcriptase inhibitor (NRTI) mutations. NRTI TDRMs were found in 8.1% (107/1,306) of patients. However, TAMs were divided into three categories and M41L, L210W, and T215Y mutations were found for TAM1 in 97 (7.4%) patients, D67N, K70R, K219E/Q/N/R, T215F, and T215C/D/S mutations were detected for TAM2 in 52 (3.9%) patients, and M41L + K219N and M41L + T215C/D/S mutations were detected for the TAM1 + TAM2 profile in 22 (1.7%) patients, respectively. Nonnucleoside reverse transcriptase inhibitor-associated TDRMs were detected in 3.3% (44/1,306) of patients (L100I, K101E/P, K103N/S, V179F, Y188H/L/M, Y181I/C, and G190A/E/S) and TDRMs to protease inhibitors were detected in 2.3% (30/1,306) of patients (M46L, I50V, I54V, Q58E, L76V, V82A/C/L/T, N83D, I84V, and L90M). In conclusion, long-term and large-scale monitoring of regional levels of HIV-1 TDRMs informs treatment guidelines and provides feedback on the success of HIV-1 prevention and treatment efforts.

A 14-year-old male patient reported with a horizontal fracture of almost the entire crown of a maxillary incisor, extending subgingivally at the palatal side. After root canal therapy and electrosurgery, the tooth fragment was reattached using a total-etch dentin-bonding system and a hybrid composite. Due to enamel cracks and the necessity for more retention, the labial surfaces of the teeth were veneered with a micro-filled composite. The clinical situation of the reattached teeth was confirmed successful by radiographic and photographic assessment after 1, 3, 6, and 12 months. The restoration of an anterior tooth with original tooth fragment in young patients has advantages over conventional composite or prosthetic restorations. However, reattached teeth with fracture extending subgingivally, require long-term follow-up.

INTRODUCTION: HIV-TR is a recently established (2012) multicentre cohort in Turkey. The aim of this study is to analyze epidemiological, immunologic and virologic data of recently diagnosed HIV patients. MATERIALS AND METHODS: Epidemiologic, clinical and laboratory data of all patients diagnosed in 2011 and 2012 were recorded by a web-based data collection system, retrospectively. RESULTS: A total of 693 patients (561 male, 132 female) at 24 sites were enrolled. The median age at first presentation for HIV care was 36. The proportion of patients presenting with advanced HIV disease (CD4 count<200/mm(3) or presenting with an AIDS-defining event) was 30.6%; and 52.4% of patients were late presenters (CD4 count<350/mm(3) or presenting with an AIDS-defining event). Median CD4 counts at presentation and before treatment were 344 (IQR: 175-540) and 295 (IQR: 150-430), respectively. Pretreatment CD4 count was >500 copies/mL in 18.5% of patients. Of 531 patients receiving ART, initial combinations consist of tenofovir/emtricitabine (TDF/FTC) plus efavirenz (EFV) in 48.2% and TDF/FTC plus lopinavir/ritonavir (LPV/r) in 37.5% and other combinations in 14.3% of the patients. Pre-treatment HIV-RNA was over 100.000 copies/mL in 52.3% of patients. At Weeks 24 and 48, HIV-RNA were<50 copies/mL in 63,4% of 385 patients and 82% of 311 patients reported to be still on ART and had a viral load measurement, respectively. Median pretreatment CD4 count was lower for TDF/FTC+LPV/r recipients than TDF/FTC+EFV recipients (250 vs 316) (p<0.05). The median increase from baseline CD4 cell count was 230 in TDF/FTC+LPV/r group, 193 in TDF/FTC+EFV group and 216 among all treated patients. Of 531 patients receiving ART, 11 had died and 19 were lost to follow-up. CONCLUSION: Despite 52.4% of recently diagnosed patients were late presenters; a high rate of virologic suppression was achieved in HIV-TR Cohort. A national HIV testing strategy targeting subpopulations with higher risk is urgently needed.
RESUMEN
Infective endocarditis caused by Gemella morbillorum is a rare disease. In this report 67-year-old male patient with G. morbillorum endocarditis was presented. The patient was hospitalized as he had a fever of unknown origin and in the two of the three sets of blood cultures taken at the first day of hospitalization G. morbillorum was identified. The transthoracic echogram revealed 14 × 10 mm vegetation on the aortic noncoronary cuspis. After 4 weeks of antibiotic therapy, the case was referred to the clinic of cardiovascular surgery for valve surgery.
RESUMEN
INTRODUCTION: The objective of this study was to determine the transmitted drug resistance mutations (TDRMs) in newly diagnosed HIV-1 positive patients in Turkey. MATERIALS AND METHODS: The study was carried out between 2009 and 2014 and antiretroviral naïve 774 HIV-1 infected patients from 19 Infectious Diseases and Clinical Microbiology Departments in Turkey were included; gender: 664 (86%) male, median age: 37 (range; 1-77), median CD4+T-cell: 360 (range; 1-1320) count/mm(3), median HIV-RNA load: 2.10+E6 (range; 4.2+E2-7.41+E8) IU/mL. HIV-1 drug resistance mutations were detected by population based sequencing of the reverse transcriptase (codon 41-238) and protease (codon 1-99) domains of pol gene of HIV-1, and analyzed according to the criteria by the World Health Organization 2009 list of surveillance drug resistance mutations [1]. RESULTS: The patients had TDRMs to NRTIs (K65R, M184V), NNRTIs (K101E, K103N/S, G190A/E/S, Y181I/C, Y188H/L) and PIs (M46L, I54V, L76V, V82L/T, N83D, I84V, L90M). The prevalence of overall TDRMs was 6.7% (52/774). Resistance mutations were found to be 0.7% (6/774), 4.1% (32/774) and 2.1% (17/774) to NRTIs, NNRTIs and PIs drug groups, respectively. Three patients had NRTIs+NNRTs resistance mutations (M184V+K103N) as multi-class drug resistance. However, thymidine analogue resistance mutations (TAMs) determined two distinct genotypic profiles in the HIV-1 reverse transcriptase: TAM1: M41L, L210W and T215Y, and TAM2: D67N, K70R, K219E/Q, and T215F. The prevalence of TAM1 and TAM2 were 7.7% (60/774) and 4.3% (34/774), respectively. CONCLUSIONS: The TDRMs prevalence of antiretroviral naïve HIV-1 infected patients may be suggested current situation of Turkey. These long-term and large-scale results show that the resistance testing must be an integral part of the management of HIV infection in Turkey.

No complaints were noted by the patients at their 1-year follow-up and the treatment showed favorable prognosis.
RESUMEN
OBJECTIVE: The aim of this study was to describe how AIDS, as well as the stigma associated with it, affects the lives of HIV positive patients and their family members. MATERIALS AND METHODS: Three large state hospitals in the metropolitan area of Izmir participated in the study. Six focus groups were conducted with people infected with HIV (n=32) and their family members (n=11). Participants were asked to fill out a questionnaire to assess their HIV/AIDS knowledge and to convey how the stigma had affected them. RESULTS: The most important problems identified were society and work-related social problems and access to health services. The patients and their family members stated that education was needed to correct misconceptions about HIV and to help them cope with related problems. We found that patients and their family members were sensitive about disclosure. CONCLUSION: We determined the education, counseling and support needs of HIV-infected patients and their families. Additionally, we found that health personnel who monitor the patients should make more efforts on patients' education and counselling.
RESUMEN
OBJECTIVE: The purpose of this study was to assess the calcium hydroxide (CH) removal potential of an Er:YAG laser in combination with ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl) irrigation. BACKGROUND DATA: Removal of the CH dressing prior to the root canal filling is mandatory, as its remnants may mechanically block the apical area of the root canal system and also have an effect on the texture, viscosity, working time, penetration, and adhesion of root canal sealers. However, the removal of CH from the canal space is challenging, because it should ideally be placed deep and densely, so that its biological effects can be exerted in close proximity to the appropriate tissues. METHODS: In this study, the mandibular premolar teeth were embedded in acrylic blocks and sectioned longitudinally through the canal, forming two halves following shaping of the root canals with ProTaper (Maillefer, Ballaigues, Switzerland) rotary instruments. The teeth were reassembled after standard grooves created onto canal walls were filled with CH. In group 1, conventional irrigation was performed with 10 mL of 17% EDTA and 10 mL of 5% NaOCl, and in goup 2, Er:YAG laser following conventional irrigation was performed. Images of the grooves taken before and after irrigation were scored and the Mann-Whitney U test was used to statistically evaluate the results. RESULTS: The percentage of CH score reduction was 46.30% in group 1 and 60.58% in group 2. No significant difference was found between two groups (p>0.05). CONCLUSIONS: The laser did not improve the removal of CH during conventional root canal irrigation performed with NaOCl and EDTA under the conditions of current study.
