Cerebrospinal Fluid Viscosity: A Novel Diagnostic Measure for Acute Meningitis
(Lippincott Williams & Wilkins, 2010) Yetkin, Funda; Kayabas, Uner; Ersoy, Yasemin; Bayindir, Yasar; Toplu, Sibel Altunisik; Tek, Ibrahim
Introduction: Early diagnosis of acute meningitis has paramount importance in clinical practice because of mortality and morbidity of the disease. Examination of cerebrospinal fluid (CSF) has critical value for the diagnosis of acute meningitis and discrimination of bacterial and aseptic meningitis. It has been previously reported that plasma viscosity can be used as an inflammatory marker. In this study we aimed to evaluate the role of CSF viscosity as a complementary measure for diagnosis of meningitis in suspected patients. Methods: Forty-one consecutive patients who underwent lumbar puncture to rule out meningitis were studied prospectively. Twenty-seven patients were diagnosed with meningitis, of whom 13 patients had aseptic meningitis and 14 patients had bacterial meningitis. Meningitis was ruled out in 14 patients. Results: CSF protein and CSF viscosity were significantly higher in patients with meningitis compared to nonmeningitis. Receiver operator characteristic (ROC) analysis revealed that CSF viscosity was highly sensitive (100%) and specific (93%); measures for the diagnosis of meningitis in the study population was comparable to those of CSF protein. Additionally, patients with meningitis were also divided into two groups as having bacterial and aseptic meningitis. CSF viscosity also significantly differed between bacterial and aseptic meningitis. Conclusion: The CSF viscosity is a simple and easy method and can be used as an adjunctive measure for the diagnosis of meningitis. With the support of further and larger clinical studies, CSF viscosity may have a role in the discrimination of bacterial versus aseptic meningitis.

(Elsevier Science Inc, 2021) Kose, Adem; Toplu, Sibel Altunisik; Yalcinsoy, Murat; Yakupogullari, Yusuf; Otlu, Baris; Otan, Emrah; Aydin, Cemalettin
Background. We aimed to evaluate the clinical characteristics and outcomes of mild-severe COVID-19 pneumonia cases in liver transplant (LT) recipients. Methods. Ten LT recipients diagnosed as having COVID-19 pneumonia in a 6-month period in our transplantation center were included. Demographic and medical data of the recipients were retrospectively collected; clinical courses, treatment responses, and outcomes were evaluated. Results. Ten LT recipients were male, had a median age of 57 years (min-max, 36-69 years; interquartile range [IQR], 13 years), and had right lobe from living donor LT performed in a median of 11 months (min-max, 1-72 months; IQR, 12 months). Five patients had severe pneumonia, and the remaining patients had mild/moderate pneumonia. The most frequent symptoms were fever (90%) and cough (70%). Favipiravir, enoxaparin sodium, and corticosteroid were initiated at the time of the diagnosis; immunosuppressive drug doses were reduced or discontinued in 3 cases. Lymphopenia median: 510/mL (min-max, 90-1400 mL; IQR, 610 mL), increased levels of C-reactive protein median: 4.72 (min-max, 0.31-23.4; IQR, 8.5), and ferritin median: 641 (min-max, 40 to >= 1650; IQR, 1108) were frequent. Four patients required antibacterial treatments because of emerging bacterial pneumonia and/or sepsis. All patients were hospitalized for a median of 10 days. One patient with sepsis died on the 26th day after intensive care unit admission, and the remaining 9 survived. No further complication was recorded for 1-month follow-up. Conclusions. Commencing favipiravir, enoxaparin sodium, and corticosteroid treatments; close follow-up of the developing complications; the temporary reduction or cessation of immunosuppression; a multidisciplinary approach; early awareness of the bacterial infections; and the initiation appropriate antibiotic treatments can contribute to success.
Clinical results and health-related quality of life in otoplasty patients using cartilage resection and suturing methods
(Springer, 2014) Toplu, Yuksel; Sapmaz, Emrah; Firat, Cemal; Toplu, Sibel Altunisik
In this study, we evaluated clinical results and health-related quality of life in our otoplasty patients in whom we used cartilage resection method (CRM) and suturing method (SM). A total of 132 ears of 77 patients (36 males, 41 females; mean age 14.6 +/- 6.4) between January 2006 and February 2013 were included in this study. Patients were divided into two groups according to the type of surgery performed: Group 1 was the cartilage resection group (CRG) and Group 2 was the suturing group (SG). CRM was performed on 64 ears of 37 patients (unilateral in 10 cases and bilateral in 27 cases), and SM was performed on 68 ears of 40 patients (unilateral in 12 cases and bilateral in 28 cases). The parameters of the groups, including operation time, measurements of the auriculocephalic distances, complication rates, postoperative satisfaction rates, and health-related quality of life were compared. Mean operation time was 53.7 +/- 7.8 min in the CRG and 44.9 +/- 4.2 min in the SG (P a parts per thousand currency sign 0.05). Mean postoperative auriculocephalic measurements were similar in both groups. The complications were more frequent in the CRG (10/37 patients, 27.02 %) than in the SG (3/40 patients, 7.54 %) with statistically significant difference (P < 0.05). Three months after the surgery, visual analog scale increased from 25 (preoperatively) to 70 in the CRG and from 30 to 90 in the SG, with a statistically significant difference (P < 0.05). Patients' health-related quality of life showed a statistically significant increase after the operation in both groups (P < 0.05). CRM and SM are effective treatment methods with high success rates for patients with prominent ears. In the selected cases, SM seems to represent a better option for otoplasty than CRM because clinical results, cosmetic outcomes, patient satisfaction, and health-related quality of life scores were better than CRM.

Comparison of Tenofovir Alafenamide and Entecavir Therapy in Patients with Chronic Hepatitis B Initially Treated with Tenofovir Disoproxil: A Retrospective Observational Survey
(Briefland, 2021) Kalkan, Irem Akdemir; Karasahin, Omer; Sarigul, Figen; Toplu, Sibel Altunisik; Aladag, Murat; Akgul, Fethiye; Mete, Ayse Ozlem
Background: In chronic hepatitis B patients with or exposed to the risk of osteoporosis or renal dysfunction, switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide fumarate (TAF) or entecavir (ETV) maybe the right choice. Objectives: This study aimed to present real-life data in terms of the efficacy and safety of a TAF/ETV treatment change while receiving TDF. Methods: This retrospective study was conducted on 344 adult patients from 10 centers. The data of patients who had changed to ETV (n = 107) and TAF (n = 237) while receiving TDF were analyzed. The data collected at 0 and 6 months of treatment were analyzed. The virological response was assessed based on undetected hepatitis B virus (HBV) DNA. Serum alanine aminotransferase (ALT) values were used to evaluate the biochemical response. For renal function, serum creatinine and phosphorus, as well as estimated glomerular filtration rate (eGFR), were recorded. Moreover, lumbar spine and hip T-scores along with the serum lipid profile were evaluated. Results: The mean age of patients was 41.14 +/- 13.46 years, and 224 (65.1%) of the participants were male. The treatment arms were not significantly different in terms of demographic characteristics, comorbid diseases, infection duration, family history of HBV infection, blood platelet count, serum biomarkers, such as ALT, phosphorus, creatinine, total bilirubin, albumin, lipid profile, and HBV DNA levels at the beginning. No statistically significant difference was found between the proportion of undetectable HBV DNA of the two treatment groups after 6 months (P = 0.221). The ALT normalization in the ETV and TAF groups at the sixth month compared to the baseline levels was not significantly different (P = 0.853, P = 0.330, respectively). There was no statistically significant difference between the two treatment arms regarding changes in eGFR, creatinine, phosphorus, hip, and spine T-scores from baseline to 6 months (P = 0.296, P = 0.78, P = 0.141, P = 0.832, P = 0.947, respectively). In those who switched to TAF or ETV, low-density lipoproteins cholesterol were observed to be significantly higher after 6 months compared to baseline values (P = 0.002, P = 0.049, respectively). The TC increased significantly in the TAF group (P = 0.035). Conclusions: Our study showed that switching to ETV and TAF sustained the viral suppression and biochemical response achieved by TDF therapy. The treatment switch to TAF of ETV can control renal dysfunction and reduce bone mineral density caused by TDF.
Evaluation of Culture-confirmed Extrapulmonary Tuberculosis Cases in a University Hospital
(Galenos Yayincilik, 2019) Toplu, Sibel Altunisik; Kayabas, Uner; Otlu, Baris; Bayindir, Yasar; Ersoy, Yasemin; Memisoglu, Funda
Introduction: Tuberculosis (TB) is caused by Mycobacterium tuberculosis and can involve any organ, especially the lungs. In recent years, especially in developed countries, the incidence of TB has increased due to the growing number of people with acquired immunodeficiency. This has led to an increase in the incidence of extrapulmonary TB (EPTB). This study examined patients with EPTB confirmed by positive M. tuberculosis culture in Inonu University Faculty of Medicine, Department of Microbiology and Clinical Microbiology, Molecular Microbiology Laboratory. Materials and Methods: Patients with positive M. tuberculosis culture in the molecular microbiology laboratory of our hospital between January 1, 2004 and December 31, 2014 were retrospectively evaluated according to culture-confirmed site of involvement, acid-fast bacillus (AFB), polymerase chain reaction (PCR) positivity, drug resistance, and mortality. Results: The study included 132 patients; 41 (31.1%) were male and 91 (68.9%) were female. The mean age was 46.4 +/- 18.5 (17-86) years. Extrapulmonary TB types were TB lymphadenitis in 48 patients (36.4%), musculoskeletal TB in 23 (17.4%), disseminated TB in 17 (12.9%), urinary TB in 11 (8.3%), abdominal TB in 11 (8.3%), TB meningitis in eight (6.1%), pleural TB in six (4.5%), genital TB in five (3.8%), and cutaneous TB in three patients (2.3%). Acid-fast bacillus positivity rates were 21.7% in musculoskeletal samples, 16.6% in pleural samples, 12.5% in cerebrospinal fluid, 9% in urinary tract samples, and 6.2% in lymph nodes. Polymerase chain reaction positivity was not detected in cerebrospinal fluid or skin samples. The rate of resistance to at least one anti-tuberculous drug was 20%. Mortality was 16.1% (n=9) in the 56 patients (42.4%) with available data. Conclusion: Lymphatic TB was the most common form in our patients. According to national data, pleural TB is among the common forms of EPTB in Turkey. However, the rate of pleural TB was low in our study due to the lack of pleural biopsy in our hospital during the study period. In TB-endemic regions such as Turkey, it is important to consider EPTB in the differential diagnosis of patients with relevant clinical findings and to confirm the diagnosis with TB culture primarily, as well as methods such as AFB staining and PCR.
Evaluation of Cytomegalovirus Infections in Liver Transplant Recipients Under Universal Prophylaxis: A Single Centre Experience
(Kowsar Publ, 2021) Toplu, Sibel Altunisik; Kose, Adem; Karakas, Serdar; Bayindir, Yasar; Otlu, Baris; Yilmaz, Sezai
Background: Cytomegalovirus (CMV) is one of the leading viral agents that can pave the way for serious complications and organ damage in solid organ transplant (SOT) recipients after transplantation. Strategies have been developed to protect at-risk patients from CMV infection following transplantation. Since more than 90% of adults in Turkey were positive for CMV IgG, universal CMV prophylaxis was applied, and the results were evaluated. Objectives: This study aimed to evaluate the results of universal CMV prophylaxis after liver transplantation in the long term. Methods: A total of 1,090 liver transplant patients were evaluated in terms of CMV infection in the Organ Transplantation Institute of Inonu University, Malatya, Turkey, from October 2014 to December 2019. In order to identify the CMV infections, quantitative nucleic acid amplification (QNAT) was used to detect potential CMV DNA. The cut-off value of CMV DNA was determined to be 1000 copies/mL after transplantation. Results: According to the clinical and laboratory assessments, 33 (3%) patients were diagnosed with CMV infection, and 25 (2.3%) patients were evaluated as possibly having CMV syndrome. Also, eight of the 33 patients were assessed as having end-organ CMV disease and 25 as probable CMV syndrome. In the late period following prophylaxis, CMV infection was observed in 10 (0.9%) cases. The infection rate after prophylaxis (0.9%) was lower than the infection rate (2.1%) seen during prophylaxis. Conclusions: Close clinical follow-up with CMV prophylaxis and strict monitoring of CMV DNA by determining a specific cut-off point are important in the follow-up of liver transplant patients.

First year real life experience with tenofovir alafenamide fumarate: The pythagorean cohort
(Kare Publ, 2023) Karasahin, Omer; Kalkan, Irem Akdemir; Dal, Tuba; Toplu, Sibel Altunisik; Harputluoglu, Murat; Mete, Ayse Ozlem; Komur, Suheyla
Background and Aim: In chronic hepatitis B infection, antiviral therapy significantly reduces the incidence of complications. This study aimed to present real-life 12-month effectiveness and safety data for TAF.Materials and Methods: This Pythagoras Retrospective Cohort Study included patients from 14 centers in Turkiye. The study presents 12-month results of 480 patients treated with TAF as initial therapy or after switching from another antiviral drug.Results: The study shows treatment of about 78.1% patients with at least one antiviral agent (90.6% tenofovir disoproxil [TDF]). The rate of undetectable HBV DNA increased in both treatment-experienced and naive patients. In TDF-experienced patients, the rate of alanine transaminase (ALT) normalization increased slightly (1.6%) within 12 months, but the change was not statistically significant (p=0.766). Younger age, low albumin, and high body mass index and cholesterol were identified as risk factors for abnormal ALT after 12 months, but no linear relationship was detected. In TDF-experienced patients, renal and bone function indicators showed significant improvement three months after the transition to TAF and remained stable for 12 months.Conclusion: Real-life data demonstrated effective virological and biochemical responses with TAF therapy. After switching to TAF treatment, gains in kidney and bone functions were achieved in the early period.
Multisystem Inflammatory Syndrome in Adults (MIS-A) Associated with SARS-CoV-2 Infection in a Young Adult Case from Turkey
(Galenos Publ House, 2021) Toplu, Sibel Altunisik; Ersoy, Yasemin; Bayindir, Yasar; Kilic, Talat; Bayazit, Volkan
Weeks and even months after recovering from the SARS-CoV-2 infection, clinically more severe cases are being reported, which are suggestive of COVID-19-related multisystemic inflammatory syndromes (MIS). Firstly on March 2020, this condition was reported to be COVID-19 related to children (MIS-C). Since June 2020, a syndrome similar to multisystem inflammatory syndrome in adults (MIS-A) came to be noticed in adults as well. We reported here a case of 24-year-old young woman who had gone to a hospital with abdominal pain and later developed a severe cough, followed by development of subconjunctival bleeding, pericardial effusion, pleural effusion, and intra-abdominal fluid that we deemed them to be acute multisystemic clinical symptoms, 47 days after she had undergone a COVID-19 infection of mild clinical severity. It should be kept in mind that a multisystemic inflammatory syndrome along with a delayed immune response during COVID-19 disease can be seen not only in children but also in young adults, and seemingly severe clinical and laboratory findings can improve by controlling the inflammatory process.
Oral colonization of Acinetobacter baumannii in intensive care units: Risk factors, incidence, molecular epidemiology, association with the occur of pneumonia and sepsis, and infection control measures
(Mashhad Univ Med Sciences, 2022) Duman, Yucel; Ersoy, Yasemin; Tanriverdi, Elif Seren; Otlu, Bans; Toplu, Sibel Altunisik; Goziikara, GOzde; Tekerekoglu, Mehmet Sait
Objective(s): Oral colonization of Acinetobacter baumannii can lead to infections such as pneumonia and sepsis. We aimed to evaluate oral colonization of hospitalized patients in ICUs and to examine risk factors for oral colonization, molecular epidemiology, and incidence of pneumonia and sepsis. Materials and Methods: The study began in February 2021. Oral cultures were taken. The microorganisms were identified by a Maldi-tof MS mass spectrometry device. Colistin resistance genes were investigated by polymerase chain reaction. Clonal relationships were determined by pulsed-field gel electrophoresis. Results: A. baumannii was found in 21 of 96 patients' oral cultures. Pneumonia and sepsis due to A. baumannii were detected in 14 and 5 patients, respectively. The mean growth time of A. baumannii from oral cultures was 11.8 days, and the meantime for the occurrence of pneumonia after oral growth was 5.2 days. We determined a plasmid mediated mcr-2 colistin resistance gene in a colistin susceptible A. baumannii strain. It is the first report of the plasmid mediated mcr-2 colistin resistance gene in our country. In total, fourteen different A. baumannii genotypes were determined in PFGE. It was determined that the effects of antibiotic use, oral motor dysfunction, mechanical ventilation, intubation, orogastric tube use, and total parenteral nutrition intake on oral colonization were statistically significant. Conclusion: Oral colonization of A. baumannii is a significant concern in ICUs. We believe that it is important to take oral cultures and follow the risk factors and take infection control measures to prevent oral colonization of resistant isolates in ICUs.

(Springer, 2014) Toplu, Yuksel; Sapmaz, Emrah; Toplu, Sibel Altunisik; Deliktas, Hacim
In this study, we evaluated our otoplasty surgery results in patients with prominent ears. A total of 76 ears in 42 patients (20 male, 22 female; mean age 14; range 6-34 years) who underwent otoplasty surgery under general anesthesia between April 2005 and February 2012 were evaluated retrospectively. Of the 76 surgical cases, while 65 were operated on for the first time (primary), 6 had had previous unsuccessful surgical interventions at other institutes (secondary) and 5 were our own revision surgery cases. Of the primary cases; 11 had unilateral and 27 had bilateral surgery. Postoperative follow-ups were performed at week one, months one, three and six and at 1 year. While 60 of the 65 primary surgeries and all 6 of the secondary surgeries had successful results, 5 cases required revision surgery. The revision otoplasty surgeries were found to be successful in all patients on follow-up visits. Otoplasty surgery is an effective treatment method with high success rates for patients with prominent ears.
Real-life Data for Tenofovir Alafenamide Fumarate Treatment of Hepatitis B: the Pythagoras Cohort
(Briefland, 2021) Karasahin, Omer; Kalkan, Irem Akdemir; Dal, Tuba; Toplu, Sibel Altunisik; Harputoglu, Murat; Mete, Ayse Ozlem; Komur, Suheyla
Background: Chronic hepatitis B (CHB) is a viral infection that can result in life-threatening conditions, such as hepatocellular carcinoma and cirrhosis. Tenofovir, which is used for the treatment of CHB, is a nucleotide analog that inhibits HBV-DNApolymerase and has two formulations: disoproxil and alafenamide. In contrast to tenofovir disoproxil fumarate (TDF), tenofovir alafenamide fumarate (TAF) penetrates the whole hepatocyte without being eliminated due to its longer plasma half-life and greater plasma stability. As a result, side effects such as proximal renal tubulopathy and loss of bone density are less common in the treatment of TAF and have similar efficacy to TDF. Objectives: The purpose of the study was to evaluate the effectiveness and reliability of TAF using real-life data. Methods: This retrospective cohort study was carried out in secondary or tertiary healthcare centers in southern Turkey. A total of 480 patients aged 18 years and older were administered TAF for an appropriate indication by the infectious diseases and gastroenterology clinics of the healthcare centers participating in this study. The data collected at t = 0, t =3, and t = 6 months of treatment were analyzed. The chi-square, Mann-Whitney U, Friedman, Wilcoxon, Cochran's Q, and McNemar's tests were used. Results: The mean age of the patients was 47.40 +/- 14.5, and 327 of them (68.1%) were male. A total of 78.1% of the 480 patients who underwent the TAF treatment had previous antiviral therapy experience (TDF, n =340; 70.8 %), and 21.9% were treatment-naive. The most common reasons for the initiation of TAF treatment were the use of drugs affecting bone mineral density (BMD) (42.9%) and osteoporosis (22.3%). Patients who had taken TDF experienced a significant improvement in glomerular filtration rate (GFR), hip and spine T-scores, and phosphorus levels from t = 0 months tot = 6 months after switching to TAF (P < 0.05). For this group, no statistically significant difference was observed concerning LDL and cholesterol levels from t= 0 months to t = 6 months. Side effects were reported by 5.7% of patients in the third month and 7.1% in the sixth month, with the most common side effect being hair loss (1%). Conclusions: TAF was found to be an effective and safe alternative to TDF with lower incidences of its long-term effects, such as nephrotoxicity and decreased bone density.

Relationship between hand hygiene and cutaneous findings during COVID-19 pandemic
(Wiley, 2020) Toplu, Sibel Altunisik; Altunisik, Nihal; Turkmen, Dursun; Ersoy, Yasemin
Background In the current situation of the COVID-19 pandemic, healthcare workers (HCWs) have to comply with hygiene conditions and use gloves more frequently and for a longer period of time than they would previously to avoid infection and prevent transmission. Aims We aimed to characterize the adverse skin reactions occurring after hand hygiene and glove use in HCWs in a tertiary university hospital to determine the possible causative factors and whether the use of these measures is affected. Methods Between April 15 and May 1, 2020, a cross-sectional survey was conducted, using online questionnaire, answered by HCWs in a tertiary university hospital. Results The increase in general hand-skin problems during the pandemic period was statistically significant (P = .004). The most common symptom was dryness. During the pandemic period, 67 (24.3%) HCWs thought that the conditions were caused by glove use, and 197 (71.4%) thought that they were due to alcohol-based hand antiseptics. The incidence of other hand-skin conditions except for vesicles was statistically higher in women than in men (P < .001). Conclusions Increased number of hand-skin conditions during the pandemic should not be ignored, since hand hygiene and glove use are expected to increase.
Short-term experiences of a liver transplant centre before and after the COVID-19 pandemic
(Wiley-Hindawi, 2021) Toplu, Sibel Altunisik; Bayindir, Yasar; Yilmaz, Sezai; Yalcinsoy, Murat; Otlu, Baris; Kose, Adem; Sahin, Tevfik Tolga
Background/Aim With the COVID-19 pandemic, managing the process of solid organ transplantation has become a significant matter for transplant centres. In this study, we report our experiences on evaluating the effects of COVID-19 in patients with recent liver transplants. Materials and Methods We evaluated patients who received liver transplants during three close consecutive periods of time. For transplants conducted between October 1 and December 31, 2019, January 1 and March 10, 2020 and March 11 and June 22, 2020, the lung tomographies of patients were inspected for radiological signs of viral pneumonia. For patients after March 11, 2020, the hospital's electronic database system was scanned for preoperative and postoperative SARS-CoV-2 testing from Real-time Polymerase Chain Reaction (RT-PCR) of the respiratory tract samples. Results A total of 149 patients over the age of 18 who received liver transplants at our centre between October 1, 2019 and June 22, 2020 were evaluated. During this time span, our centre conducted liver transplants on patients from 34 different provinces and also abroad. Within this time period, a total of nine patients had respiratory samples with a positive SARS-CoV-2 RT-PCR test. PCR of respiratory tract samples was performed in 21 (14%) patients to identify the other potential infective agents in the respiratory tracts; Rhinovirus and Influenza A were detected in two and respiratory syncytial virus (RSV) was detected in one patient. During the transplant periods, 99 (67.1%) patients were evaluated with computed tomography (CT). The CT findings of 18 (12%) patients were consistent with viral pneumonia. There was a statistically significant difference between the groups only in terms of air bronchogram findings (P = .012). Conclusion The clinical status of our short-term liver transplant patients was far better than we originally anticipated, but it remains obvious that the necessary precautions should continue to be taken.
A silent outbreak due to Klebsiella pneumoniae that co-produced NDM-1 and OXA-48 carbapenemases, and infection control measures
(Mashhad Univ Med Sciences, 2020) Duman, Yucel; Ersoy, Yasemin; Gursoy, Nafia Canan; Toplu, Sibel Altunisik; Otlu, Baris
Objective(s): ): Infections due to carbapenemase-producing Klebsiella pneumoniae are associated with high morbidity and mortality. In this study, we report a hospital outbreak due to co-producing OXA-48 and NDM-1 K. pneumoniae clone. The aim of the study is to investigate the clonal relationship of strains, risk factors of outbreak and infection control measures. Materials and Methods: Once an outbreak was suspected at the end of December 2017 in our intensive care unit (ICU), carbapenem resistance K. pneumoniae identified in patients' specimens. An outbreak analysis was begun to determine the risk factors and dissemination of the cases. A case-control study was conducted to determine the risk factors. To control the outbreak; tight contact prevention, good clean-up the medical devices and hospital environment, were done. Staff training programs such as hand hygiene, disinfection, wearing aprons, good cleaning were created. Carbapenem resistance genes determined by PCR. Clonal relationships of strains investigated by PFGE. Results: We investigate 21 carbapenem-resistant K. pneumonia strains. Nine of them were found co-produced NDM-1 and OXA-48, 11 strains produced OXA-48, and one strain produced NDM-1. Seven strains of co-producing NDM-1 and OXA-48 were found clonally related with PFGE. We could not determine any risk factor except rectal colonization in the case-control study. Conclusion: The interventions that successfully controlled this outbreak were hand hygiene, tight contact prevention, good clean-up of the hospital environment and medical devices. As a result, we believe that it would be beneficial to take infection control measures to prevent the spread of these strains to the community and hospital settings.
An Unusual Cause of Conductive Hearing Loss: Bilateral Complete Meatal Obstruction Following Otoplasty
(Lippincott Williams & Wilkins, 2014) Toplu, Yuksel; Toplu, Sibel Altunisik; Sapmaz, Emrah; Deliktas, Hacim
There are many causes of conductive hearing loss. Otoplasty is a commonly performed cosmetic surgery to correction for prominent ear. We discussed an unusual cause of conductive hearing loss, bilateral complete meatal obstruction following otoplasty, in this article. This complication was probably due to unsuitable placement of the Furnas sutures. In the literature, as a cause of conductive hearing loss, unilateral complete meatal obstruction has been described rarely, but bilateral complete obstruction has not been defined. Hearing loss recovered completely after revision surgery. Correct diagnosis, accurate preoperative or perioperative examination, choice of the proper technique and surgeon experience are essential for avoiding inadequate results or complications of otoplasty. The surgeon should be aware of the cartilage elasticity and suture techniques to avoid this complication.
