RESUMO
OBJECTIVES: To uncover clinical epidemiology, microbiological characteristics and outcome determinants of hospital-acquired bloodstream infections (HA-BSIs) in Turkish ICU patients. METHODS: The EUROBACT II was a prospective observational multicontinental cohort study. We performed a subanalysis of patients from 24 Turkish ICUs included in this study. Risk factors for mortality were identified using multivariable Cox frailty models. RESULTS: Of 547 patients, 58.7% were male with a median [IQR] age of 68 [55-78]. Most frequent sources of HA-BSIs were intravascular catheter [182, (33.3%)] and lower respiratory tract [175, (32.0%)]. Among isolated pathogens (nâ=â599), 67.1% were Gram-negative, 21.5% Gram-positive and 11.2% due to fungi. Carbapenem resistance was present in 90.4% of Acinetobacter spp., 53.1% of Klebsiella spp. and 48.8% of Pseudomonas spp. In monobacterial Gram-negative HA-BSIs (nâ=â329), SOFA score (aHR 1.20, 95% CI 1.14-1.27), carbapenem resistance (aHR 2.46, 95% CI 1.58-3.84), previous myocardial infarction (aHR 1.86, 95% CI 1.12-3.08), COVID-19 admission diagnosis (aHR 2.95, 95% CI 1.25-6.95) and not achieving source control (aHR 2.02, 95% CI 1.15-3.54) were associated with mortality. However, availability of clinical pharmacists (aHR 0.23, 95% CI 0.06-0.90) and source control (aHR 0.46, 95% CI 0.28-0.77) were associated with survival. In monobacterial Gram-positive HA-BSIs (nâ=â93), SOFA score (aHR 1.29, 95% CI 1.17-1.43) and age (aHR 1.05, 95% CI 1.03-1.08) were associated with mortality, whereas source control (aHR 0.41, 95% CI 0.20-0.87) was associated with survival. CONCLUSIONS: Considering high antimicrobial resistance rate, importance of source control and availability of clinical pharmacists, a multifaceted management programme should be adopted in Turkish ICUs.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is the increased pressure with normal cerebrospinal fluid (CSF) composition, not due to a secondary cause. However, the need for lumbar puncture, an invasive method in diagnosis, leads to research on noninvasive diagnostic methods. This study aims to examine the role of the size of the pituitary gland and the previously unevaluated pineal gland in radiological diagnosis in patients with IIH. MATERIALS AND METHODS: The study retrospectively included 57 patients aged 18-80 years, who were followed up in our clinic with the diagnosis of IIH, and 52 control patients without central nervous system disease and cranial MR pathology. CSF pressure measurement values, CSF biochemistry, and cytology examinations were recorded as a result of lumbar puncture performed in the lateral decubitus position of all patients. In addition, the pineal gland and pituitary dimensions were measured by a neuroradiologist on cranial MR imaging of both groups. RESULTS: Pituitary gland height, anteroposterior (AP), and transverse dimensions were found to be significantly lower in the IIH patient group than in the control group (p<0.05). There were a significant reduction in pineal gland AP and height measurements in the IIH patient group compared to the control group. Still, we found no significant difference between the two groups in transverse measurements (p>0.05). CONCLUSION: Our findings suggest that measurement of pituitary and pineal gland sizes in neuroimaging may be a guide as a noninvasive method in diagnosing and treating IIH.
RESUMO
Objectives: The aim of the study was to evaluate the relationship among lower esophageal sphincter pressure (LESP), Helicobacter pylori (Hp), and gastroesophageal reflux (GER). Methods: The retrospective study included patients with isolated hypertensive or hypotensive lower esophageal sphincter (LES) who underwent esophageal manometry in our gastroenterology motility laboratory and had normal manometry results. Demographic characteristics, complaints on admission, upper endoscopy findings, 24-h esophageal pH monitoring results, and presence of Hp in gastric biopsy were evaluated. Results: A total of 1226 patients were included in the study, among whom women comprised 54% of all patients. Mean age was 45.4±13.4 years. Most common presenting complaint was pyrosis (85.4%). Pathological reflux was detected in 61.4% of the patients in 24-h esophageal pH monitoring. Reflux esophagitis was detected in 22.9% and LES laxity was present in 17.4% of the patients. In gastric biopsy, Hp was positive in 40% of the patients. The age of patients with hypertensive LES was significantly higher and female gender and body mass index (BMI) were associated with hypertensive LES. Pyrosis was significantly less prevalent in patients with hypertensive LESP. Esophagitis and LES laxity were significantly more prevalent in patients with hypotensive LES. No significant difference was found among the three groups with regard to reflux and Hp positivity. No significant difference was found between Hp-positive and Hp-negative groups with regard to reflux and reflux esophagitis. Conclusion: No clear relationship was found among LES disorders, GER, and Hp. Moreover, no significant difference was found among LES disorders with regard to GER, while the presence of hypotensive LESP, rather than Hp, was found to be an important factor in the development of reflux esophagitis.
RESUMO
BACKGROUND: The study aimed to describe the epidemiology and outcomes of hospital-acquired bloodstream infections (HABSIs) between COVID-19 and non-COVID-19 critically ill patients. METHODS: We used data from the Eurobact II study, a prospective observational multicontinental cohort study on HABSI treated in ICU. For the current analysis, we selected centers that included both COVID-19 and non-COVID-19 critically ill patients. We performed descriptive statistics between COVID-19 and non-COVID-19 in terms of patients' characteristics, source of infection and microorganism distribution. We studied the association between COVID-19 status and mortality using multivariable fragility Cox models. RESULTS: A total of 53 centers from 19 countries over the 5 continents were eligible. Overall, 829 patients (median age 65 years [IQR 55; 74]; male, n = 538 [64.9%]) were treated for a HABSI. Included patients comprised 252 (30.4%) COVID-19 and 577 (69.6%) non-COVID-19 patients. The time interval between hospital admission and HABSI was similar between both groups. Respiratory sources (40.1 vs. 26.0%, p < 0.0001) and primary HABSI (25.4% vs. 17.2%, p = 0.006) were more frequent in COVID-19 patients. COVID-19 patients had more often enterococcal (20.5% vs. 9%) and Acinetobacter spp. (18.8% vs. 13.6%) HABSIs. Bacteremic COVID-19 patients had an increased mortality hazard ratio (HR) versus non-COVID-19 patients (HR 1.91, 95% CI 1.49-2.45). CONCLUSIONS: We showed that the epidemiology of HABSI differed between COVID-19 and non-COVID-19 patients. Enterococcal HABSI predominated in COVID-19 patients. COVID-19 patients with HABSI had elevated risk of mortality. Trial registration ClinicalTrials.org number NCT03937245 . Registered 3 May 2019.

We aimed to decide which scoring system is the best for the evaluation of the course of Crimean-Congo Hemorrhagic Fever (CCHF) by comparing scoring systems such as qSOFA (quick Sequential Organ Failure Assessment), SOFA (Sequential Organ Failure Assessment), APACHE II (Acute Physiology and Chronic Health Evaluation II) and SGS (Severity Grading System) in centers where patients with CCHF were monitored. The study was conducted with patients diagnosed with CCHF in five different centers where the disease was encountered most commonly. Patients having proven PCR and/or IgM positivity for CCHF were included in the study. The scores of the scoring systems on admission, at the 72nd hour and at the 120th hour were calculated and evaluated. The data of 388 patients were obtained from five centers and evaluated. SGS, SOFA and APACHE II were the best scoring systems in predicting mortality on admission. All scoring systems were significant in predicting mortality at the 72nd and 120th hours. On admission, there was a correlation between the qSOFA, SOFA and APACHE II scores and the SGS scores in the group of survivors. All scoring systems had a positive correlation in the same direction. The correlation coefficients were strong for qSOFA and SOFA, but poor for APACHE II. A one-unit rise in SGS increased the probability of death by 12.818 times. qSOFA did not provide significant results in predicting mortality on admission. SGS, SOFA and APACHE II performed best at admission and at the 72nd and 120th hours.

Objectives: Coronavirus disease 2019 (COVID-19)-related lockdown may have a negative effect on the neuropsychiatric status of Alzheimer's disease (AD) cases. In this study, it was aimed to find future implications by evaluating the neuropsychiatric conditions of AD cases during total and partial lockdown periods. Methods: It is a prospective, cross-sectional, and multicenter study that includes AD cases which have been followed for at least 1 year by outpatient clinics from different regions of Turkey. Sociodemographic data, comorbidities, mobility, existence of social interactions, clinical dementia rating (CDR) scale, and neuropsychiatric inventory (NPI) for total and partial lockdown were questioned by the caregivers with the help of case files of the patients. Results: A total of 302 AD cases were enrolled to the study (mean age: 78±8 years, mean duration of education: 5.8±9 years). The total comorbidity ratio was found to be 84%, with the most frequent comorbidity being hypertension. The mean NPI score was 22.9±21 in total lockdown and 17.7±15 in partial lockdown, which is statistically significantly different. When lockdown periods were compared with the total scores of NPI scores according to gender, existence of social interactions, mobility, and comorbidities were found higher in the total lockdown than the partial lockdown. When switching from total lockdown to partial lockdown, the presence of comorbidities, mobility, and CDR were found to be factors that had a significant effect on NPI scores. In regression analysis, CDR score was found as the most effective parameter on the neuropsychiatric status of AD cases for both lockdown periods. Conclusion: When lockdown-related restrictions were reduced, the neuropsychological conditions of AD cases were significantly improved. Lockdown rules should be considered with these data in mind.
RESUMO
Objective: While the coronavirus disease 2019 (COVID-19) pandemic was continuing at full speed, patients with Crimean-Congo hemorrhagic fever (CCHF), which is endemic in our region, apply to the emergency department simultaneously. The presence of computed tomography (CT) lesions suggesting COVID-19 in some CCHF patients has brought to our mind the question of whether there is CCHF lung involvement even though respiratory symptoms are not at the forefront. Methods: In this study, the findings of chest CT, demographic data and clinical symptoms of cases who had thorax tomography scan with suspicion of COVID-19 in the emergency department in the spring and summer of 2020 and were diagnosed with CCHF as a result of the evaluation and followed up in our clinic were compared with the findings of COVID-19 cases that were hospitalized and treated in the same period. Results: Seventy-seven COVID-19 and 25 CCHF cases were included in the study. Myalgia, headache, diarrhea, nausea and vomiting were significantly higher in CCHF patients ( p<0.05). Cough was significantly more common in COVID-19 patients ( p=0.034). Ground-glass opacity (GGO) was the most common tomography finding in CCHF, and cases without lung involvement were significantly higher (p=0.001). GGO, consolidation, vascularization, atelectasis band, reverse halo, air-bubble, nodule were significantly high in COVID-19 patients. Conclusion: During the epidemic period, no pathological finding was found in thoracic CT in most of the CCHF cases, and the presence of involvement in the lung tomography in cases with similar clinical and laboratory findings should primarily suggest the diagnosis of COVID-19.
RESUMO
Leptospirosis can present with severe cases such as polymyositis, peripheral neuropathy, and rarely, Guillain-Barré Syndrome (GBS). This paper reports a case who presented with dysarthria and GBS. A female patient presented with complaints of weakness, dizziness, diarrhea, and dysarthric. Her assessments included muscle strength globally 4/5 and deep tendon reflexes as hypoactive. An electromyographic examination was performed with the increase of weakness in the lower extremities, which indicated findings compatible with GBS. Antibodies against Leptospira biflexa serovar Patoc 1 at 1/400 titer were detected in the microscopic agglutination test (MAT). Neurological involvement in leptospirosis cases can range from meningoencephalitis to GBS.
RESUMO
BACKGROUND: The initial treatment for fecal incontinence (FI) includes supportive treatment and medical treatment. If the initial treatment fails, biofeedback therapy (BFT) is recommended. However, there are limited and conflicting results in the literature supporting the beneficial effect of BFT for FI. The aim of the study is to analyze the efficacy of BFT in 126 patients who have FI due to several causes. METHODS: The data of 126 patients (88 females (69.8%) and 38 males (30.2%)) were collected retrospectively. Colonoscopy, anorectal manometry (ARM), and 3D-Endoanal ultrasonography (EAUS) were performed for all patients before applying BFT. In addition, all patients received toilet training instruction and training in Kegel and other pelvic floor strengthening exercises from an experienced nurse, before BFT. RESULTS: The median age of participants was 54 years (range 18-75 years). While 80 patients (63.5%) had clinical and manometric benefit from BFT, 46 patients (36.5%) did not respond to BFT. According to the EAUS and ARM findings, BFT was beneficial in patients who had partial external sphincter failure, and was unsuccessful in patients who had both internal and external sphincter failure, both internal and external sphincter tears, and external sphincter tear rates of more than 25%. After BFT, significant increases in squeeze pressures were observed, with this increase being higher in the positive-response group. CONCLUSION: The results suggest that BFT is effective in the treatment of FI for specific patient populations.

INTRODUCTION: The purpose of the present study is to examine the frequency of headaches based on their relationship with seizures in epileptic patients as well as types of these headaches, and their clinical characteristics. METHODS: 100 patients with epilepsy (60 female, 40 male), who applied to the epilepsy outpatient clinic of Faculty of Medicine of Uludag University, were included in the study after accepting their consent forms. Patients with symptomatic epilepsy, secondary headaches and mental retardation were excluded from the study. Patients with epilepsy were divided into two groups as the patients with or without headaches associated with seizure. In addition, according to their temporal relationships with seizures, headaches were grouped as preictal, ictal and postictal headaches and the characteristics of headaches associated with seizure were examined and the patients with and without headache associated with seizure were compared in terms of their demographic and clinical features. RESULTS: In this study, the prevalence of headache associated with seizure was found as 42%. Headaches associated with seizure were more frequent in the postictal period and they were mostly characterized as migraine-like headache. According to the seizure periods, 22 (52.3%) of the patients experienced pain during every seizure period. It was determined that preictal headache was frequently migraine-like compared to postictal headache and this headache was more frequently accompanied by aura. CONCLUSION: Headache and epilepsy are the most frequent paroxysmal neurological conditions. However, because the symptoms of epilepsy are more remarkable, and its clinical presentation has a more dramatic picture, additional neurological conditions may be overlooked. Since both epilepsy and headache symptoms decrease the quality of life, it is important to treat both conditions. Examination of the correlation between these two situations can guide the physicians for selecting the treatment type, as well as helping them to improve the quality of life.
RESUMO
PURPOSE: Since many different rates have been reported in the literature and the studies conducted are mostly based on the patient anamnesis, it was aimed to analyze the olfactory dysfunction in Coronavirus Disease 2019 (COVID-19) quantitatively and to reveal its progress by time. METHODS: Patients who described new-onset olfactory dysfunction, who were treated in the COVID-19 departments of our hospital and whose PCR tests demonstrated SARS-CoV-2 presence were included in the study and they were investigated prospectively. Clinical information of all the patients was taken and the levels of olfactory function were detected using the Brief Smell Identification Test (BSIT). Scores equal to or below 8 are considered as olfactory dysfunction. Patients who were followed up for 3 months were reevaluated with the BSIT test at the end of the third month and the progression of the symptom was investigated. RESULTS: The mean BSIT test score of the 42 patients (23 female patients, 19 male patients, mean age: 41.2 ± 14.6) was 5.2 ± 2.2. There was severe olfactory dysfunction in 16.7% of the patients (0-2 points), moderate olfactory dysfunction in 31% (3-5 points), and mild olfactory dysfunction in 52.4% (6-8 points). After a follow-up for 3 months, full recovery was observed in 36 patients (85.7%) and the mean test score rose to 9.9 ± 1.8. Although olfactory dysfunction persisted in 6 patients, an elevation in test scores was noted. Olfactory dysfunction was the first symptom in 17 patients (40%) and the other symptoms occurred after 2 days (1-6) on average. CONCLUSION: We investigated olfactory dysfunction caused by COVID-19 using BSIT, and found a high rate of moderate-mild level symptoms with a high level of recovery in the 3-month follow-up. The finding revealing that olfactory dysfunction was the first symptom in 40% of the patients suggests the importance of inquiry on olfactory functions for the early diagnosis of the disease.

OBJECTIVE: Autonomic dysfunction in patients with RLS has been described in some domains; however, detailed studies on this subject are limited and report conflicting results. In this study, we aimed to evaluate autonomic functions electrophysiologically and clinically in patients with restless legs syndrome (RLS). METHODS: Fifty-two adult patients with RLS and 40 healthy controls were enrolled in this prospective study. Electrophysiological tests of sympathetic skin response (SSR) and RR interval variability (RRIV) analysis were performed, and the SCOPA-AUT questionnaire was applied to evaluate autonomic functions. RESULTS: There was no significant difference in terms of SSR results between patients and controls (p > 0.05). However, there were significant differences between the patient and control groups in terms of RRIV analyses at rest, deep breathing, and valsalva, and also valsalva ratio (p = 0.037, p = 0.049, p = 0.017, p = 0.020). The mean SCOPA-AUT total score was higher in the RLS group compared with the control group (20.7 ± 10 vs 14.2 ± 8; p = 0.003). Significant differences were found regarding gastrointestinal, urinary, and cardiovascular domains (p = 0.01, p = 0.007, p = 0.049); on the other hand, pupillomotor, thermoregulatory, and sexual function did not significantly differ (p > 0.05). CONCLUSION: Autonomic functions should be questioned in detail as well as motor and sensory symptoms of RLS, and care should be taken especially on cardiac dysfunction.

We describe a 50-year-old male patient who was admitted to the emergency department with complaints of fever and fatigue that had suddenly started two weeks ago. In the laboratory evaluation, a white blood cell count of 131.000/mm3 was detected. The patient was hospitalized and developed fecal incontinence on the first day of hospitalization. Detailed neurological examination revealed the patient had tetraparesis. Long segment high signal intensity was observed on spinal MRI. Flow cytometry examination of the CSF and biopsy findings of the bone marrow were compatible with Chronic Lymphocytic Leukemia (CLL). The patient's MRI appearances resolved after treatment. The tetraparesis resolved partially. There was no motor deficit in upper extremities and the patient was able to walk without aid or rest for 100 m. Clinical manifestation of central nervous system (CNS) involvement in CLL is heterogeneous and therefore may be difficult to pinpoint. We have described an uncommon occurrence of CNS involvement in CLL.

Crimean-Congo hemorrhagic fever (CCHF) is fatal. Therefore, it is very important to use an inexpensive, easily accessible, quick and accurate screening index based on clinical signs and laboratory parameters to identify patients suspected of having CCHF. Laboratory test results on the day of hospitalization for 268 inpatients suspected of having CCHF were used to calculate the laboratory section of the Hitit Index, while 65 of these were also monitored daily during their hospital stay to develop the clinical section of the Hitit Index. Two-hundred CCHF-negative outpatients were also evaluated. One-hundred and forty-nine inpatients were CCHF-positive and 119 inpatients were CCHF-negative. The Hitit Index is 5.6 - (5.3*lymphocyte) - (0.02*fibrinogen) - (12*direct bilirubin) + (0.04*AST) + (0.32*hematocrit) - (0.5*neutrophil) - (0.07*CKD-EPI) - (0.001*CK) ± conjunctival hyperemia (+1.5 in conjunctival hyperemia presence and -1.5 in conjunctival hyperemia absence). In 65 inpatients monitored daily, Hitit Index results for CCHF-positive and negative inpatients were 6.10(1.90-12.30) and -5.35(-8.83- -1.95), while CCHF-negative outpatients were -10.99(-15.64- -6.95) (Pâ¯<â¯0.001), respectively. On hospitalization day, just one inpatient was false-negative in 27 CCHF-positive inpatients, while four were false-positive among 38 CCHF-negative inpatients using the Hitit Index. After 24â¯h, just one inpatient was diagnosed falsely among 27 CCHF-positive and 38 CCHF-negative inpatients, and there was no change after 48â¯h. Management of patients living in endemic regions suspected of having CCHF could be achieved within minutes using the Hitit Index. Patients with Hitit Index less than zero can be monitored as outpatients, while patients with Hitit Index results above zero must be hospitalized in infectious diseases wards. This study was not registered since it was retrospective.

BACKGROUND/AIMS: Progressive hepatic fibrosis is the main predictor of outcome and prognosis in chronic liver diseases. The importance of the coagulation cascade has been defined in liver fibrosis; however, the role of the fibrinolytic pathway has not been clear yet. We aimed to evaluate the association between the plasma levels of soluble urokinase Plasminogen Activator Receptor (uPAR) and the severity of liver fibrosis in chronic hepatitis B, C and Non-Alcoholic Fatty Liver Disease (NAFLD). METHODS: 96 chronic hepatitis B, 22 chronic hepatitis C and 11 NAFLD patients together with 47 healthy controls were enrolled in the study. uPAR plasma levels were detected by Enzyme-Linked Immunosorbent Assay (ELISA) method. RESULTS: The plasma levels of uPAR in patients with chronic hepatitis B and C significantly exceeded those of healthy controls (P < 0.001) while mean uPAR levels in patients with NAFLD were not different from healthy controls. Mean uPAR levels in chronic viral hepatitis patients with F1-F3 fibrosis and F4-F6 fibrosis were higher than those of control group (P < 0.001). Mean uPAR level in patients with F4-F6 fibrosis was significantly higher than that of patients with F1-F3 fibrosis (P < 0.001). CONCLUSION: This is the first study that investigated uPAR as a fibrosis marker in NAFLD and chronic hepatitis B patients. It is suggested that plasma levels of uPAR are closely related to the fibrosis stage in chronic hepatitis B and C and that uPAR might be a noninvasive marker of liver fibrosis.
RESUMO
INTRODUCTION: Influenza subtypes vary by clinical, radiological, and prognostic courses and may go along with viral pneumonia. We aimed to identify clinical, radiological, and prognostic aspects of influenza epidemic during years 2016-2017. MATERIALS AND METHODS: Influenza cases reported to the Public Health Directorate in our city was assessed retrospectively. Clinical, radiological, and prognostic parameters were compared based on influenza subtypes. RESULT: We analyzed samples from 197 cases with suspected influenza. Mean age of the subjects was 51.17 ± 26.74. We found influenza A/H1N1, influenza A/H3N2, and influenza B in 59 (30.0%), 29 (14.7%), and 3 (1.5%) cases, respectively. Comorbidity was present in 48 (24.4%) cases. Most common radiological finding was interstitial pattern. Seventy-one and 79 per cent of H1N1 and H3N2 cases were influenza pneumonia, respectively. The prevalence of overall mortality was 5.5% with a predominance in H1N1 over H3N2. Influenza vaccination had been performed in 6.8% and 3.4% of H1N1 and H3N2 cases, respectively. We detected no mortality in any vaccinated patient. We identified 6 pregnant women, 2 of which ended up with preterm birth, and another one with abortion. CONCLUSIONS: Often manifested as lower respiratory tract infection, influenza may cause epidemics with increased mortality rate. Influenza should be suspected when interstitial pattern was seen on radiological images. H1N1 cases course worse. Since the prognosis is better in vaccinated patients, seasonal influenza vaccination among the community needs to be elevated. In addition, protective measures like vaccination should be taken in pregnancy to avoid preterm delivery or abortion.

Crimean-Congo hemorrhagic fever (CCHF) is a severe human infection caused by CCHF virus (CCHFV). Today, although the literature on CCHF pathogenesis is still limited, it is thought to be associated with immunosuppression in the early phase of infection followed by pro-inflammatory immune response that may lead to fatal outcomes. The aim of this study is to investigate the role of regulatory T-cells (Treg cells) in the pathogenesis of CCHFV. Peripheral blood mononuclear cell samples collected from 14 acute CCHF patients with mild disease course and 13 healthy subjects were included in this study. Treg expression and functional levels were analyzed by flow cytometry. Treg cells were identified as CD4+CD25â¯+â¯CD127dim cells, and their functional levels were compared by measuring their ability to suppress CD69 and CD154 expression by activated T-cells. The flow cytometry analysis revealed that total T-cell and helper T-cell levels did not vary between the two groups. In contrast, CCHF patients displayed higher Treg cell levels but lower Treg suppressive activities when compared with control subjects. This is the first study on the involvement of Treg cells in CCHF pathogenesis. Our results indicate that even though Treg cell levels are elevated during acute phase of CCHF infection, not all generated Treg cells has immunosuppressive capacity, and therefore may not represent 'true' Treg cell population. Future studies on the intrinsic mechanisms responsible for the reduced Treg inhibitory activities are required for further enlightening the CCHF pathogenesis, especially in the acute phase of the disease.

BACKGROUND: Multiple sclerosis (MS) is a common chronic neurological disease that causes disability. MS can have various clinical manifestations, one of which is olfactory dysfunction. In clinical practice, olfactory disturbances are usually underdiagnosed. The aim of our study is to assess olfactory function and its relationship with MS disease duration, disability and cognition. METHOD: We assessed 31 MS patients and 24 healthy controls matched in sex and age at our MS outpatient clinic of the Istanbul Education and Research Hospital Neurology Department. Each subject was interviewed to obtain demographic data. The Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test and Montreal Cognitive Assessment (MOCA) were applied to each participant. RESULTS: The CCCRC test scores of the MS patients were lower than those in the control group (pâ¯<â¯0.05). Patients with a longer disease duration and more frequent attacks had lower CCCRC scores (pâ¯<â¯0.05). The Expanded Disability Status Scale scores had no correlation with the CCCRC test scores. The MOCA score was positively correlated with all domains of the olfactory test scores. CONCLUSION: This study supports the presence of olfactory dysfunction in early stages of MS and the correlation of cognitive impairment with olfactory dysfunction, even in the early stages of the disease in young and less physically- disabled patients. The assessment of olfaction may be helpful as a surrogate method for tracking disease progression in patients over time.

ABSTRACT The effectiveness of prevention bundles on the occurrence and mortality of ventilator associated pneumonia (VAP) was evaluated in many studies. However, the effectiveness of endotracheal tube with subglottic secretion drainage (ETT-SD) and cuff pressure monitorization in VAP bundles have not been adequately assessed. In this study, we aimed to evaluate the effectiveness of VAP bundle containing ETT-SD and cuff pressure monitorization. This was a prospective, controlled study that was carried out between March 2011 and April 2012 including intubated patients. The study was conducted at the Anesthesiology Intensive Care Unit 1 and 2 (10 beds each) in a 898-bed university hospital. Occurrence of VAP and compliance with the parameters of the VAP prevention bundles were assessed daily. Patients intubated with the standard endotracheal tube were recruited as controls, mainly in the first six months of the study as ETT-SD and cuff pressure monometer had not yet been implemented. In the second term, patients intubated with ETT-SD were included as cases. Occurrence of VAP, mortality, and compliance with VAP prevention bundles were monitored. A total of 133 patients, 37 cases and 96 controls were recruited. VAP incidence declined from 40.82 to 22.16 per 1000 ventilator days among controls and cases, respectively (p < 005). On average, VAP occurred 17.33 ± 21.09 days in the case group and 10.43 ± 7.83 days in the control group (p = 0.04). However, mortality of cases and controls at the 14th and 30th days was not different. VAP prevention bundles including the utilization of ETT-SD, monitoring cuff pressure, and oral care with chlorhexidine were efficient in reducing the rate of VAP.
