Abstract Background: S. aureus(SA) infective endocarditis (IE)has a very high mortality, attributed to the age and comorbidities of patients, inadequate or delayed antibiotic treatment, and methicillin resistance, among other causes. The main study objective was to analyze epidemiological and clinical differences between IE by methicillin-resistantversusmethicillin-susceptible SA (MRSA vs. MSSA) and to examine prognostic factors for SA endocarditis, including methicillin resistance and vancomycin minimum inhibitory concentration (MIC) values >1 ug/mL to MRSA. Methods: Patients with SA endocarditis were consecutively and prospectively recruited from the Andalusia endocarditis cohort between 1984 and January 2017. Results: We studied 437 patients with SA endocarditis, which was MRSA in 13.5% of cases. A greater likelihood of history of COPD (OR 3.19; 95% CI 1.41-7.23), invasive procedures, or recognized infection focus in the three months before IE onset (OR 2.9; 95% CI 1.14-7.65) and of diagnostic delay (OR 3.94; 95% CI 1.64-9.5) was observed in patients with MRSA versusMSSA endocarditis. The one-year mortality rate due to SA endocarditis was 44.3% and associated with decade of endocarditis onset (1985-1999) (OR 8.391; 95% CI (2.82-24.9); 2000-2009 (OR 6.4; 95% CI 2.92-14.06); active neoplasm (OR 6.63; 95% CI 1.7-25.5) and sepsis (OR 2.28; 95% CI 1.053-4.9). Methicillin resistance was not associated with higher IE-related mortality (49.7 vs. 43.1%; p= 0.32). Conclusion:MRSA IE is associated with COPD, previous invasive procedure or recognized infection focus, and nosocomial or healthcare-related origin.Methicillin resistance does not appear to be a decisive prognostic factor for SA IE.

Abstract Background Non-paroxysmal (NPAF) forms of atrial fibrillation (AF) have been reported to be associated with an increased risk for systemic embolism or death. Methods Comparison of procedural details and long-term outcomes in patients (pts) with paroxysmal AF (PAF) against controls with NPAF in the prospective, multicentre observational registry of patients undergoing LAAC (LAARGE). Results A total of 638 pts (PAF 274 pts, NPAF 364 pts) were enrolled. In both groups, a history of PVI was rare (4.0% vs 1.6%, p = 0.066). The total CHA2DS2-VASc score was lower in the PAF group (4.4 ± 1.5 vs 4.6 ± 1.5, p = 0.033), while HAS-BLED score (3.8 ± 1.1 vs 3.9 ± 1.1, p = 0.40) was comparable. The rate of successful implantation was equally high (97.4% vs 97.8%, p = 0.77). In the three-month echo follow-up, LA thrombi (2.1% vs 7.3%, p = 0.12) and peridevice leak > 5 mm (0.0% vs 7.1%, p = 0.53) were numerically higher in the NPAF group. Overall, in-hospital complications occurred in 15.0% of the PAF cohort and 10.7% of the NPAF cohort (p = 0.12). In the one-year follow-up, unadjusted mortality (8.4% vs 14.0%, p = 0.039) and combined outcome of death, stroke and systemic embolism (8.8% vs 15.1%, p = 0.022) were significantly higher in the NPAF cohort. After adjusting for CHA2DS2-VASc and previous bleeding, NPAF was associated with increased death/stroke/systemic embolism (HR 1.67, 95% CI 1.02–2.72, p = 0.041). Conclusion Atrial fibrillation type did not impair periprocedural safety or in-hospital MACE patients undergoing LAAC. However, after one year, NPAF was associated with higher mortality.

ABSTRACT Periprosthetic joint infection (PJI) is a rare but devastating complication of total joint arthroplasty. Identifying the offending infectious agent is essential to appropriate treatment, and uncommon pathogens often lead to a diagnostic delay. This case describes the first known instance of a total knee arthroplasty (TKA) with Rothia mucilaginosa, a typical respiratory tract organism. This report aims to provide insight into the treatment of this atypical PJI, as there are only six previously published cases of Rothia species PJI septic arthritis. The patient is a 64-year-old diabetic male who underwent a right TKA and left TKA ∼6 months later. Approximately 3 weeks status post-left TKA, he showed evidence of left PJI. One year after treatment and recovery from his left PJI, he presented with several months of right knee pain and fatigue. Subsequent labs and imaging revealed right PJI. No recent history of dental disease or work was observed. He then underwent two-stage revision right knee arthroplasty and microbial cultures yielded Rothia mucilaginosa. After initial empiric treatment, antibiotic therapy was narrowed to 6 weeks of vancomycin. Following negative aspiration cultures the patient underwent reimplantation of right TKA components. One year following treatment, the patient was fully recovered with no evidence of infection. This case emphasizes the possibility of microbial persistence despite various antibiotic treatment regimens for the patient’s contralateral knee arthroplasty and PJI. Additionally, this case demonstrates the importance of two-stage revision in patients with PJI, and the viability of treating Rothia species PJIs with vancomycin.

Abstract Background Infective endocarditis (IE) is frequently caused by streptococcal species. However, there is limited knowledge about the relationship between different streptococcal species and IE, and their associated outcomes. Purpose To examine the prevalence of streptococci at species level in IE, and to relate these different species to outcomes. Methods From 2002–2012 we prospectively collected consecutive patients with IE admitted to two tertiary heart centres covering a catchment area of 2.4 million people. The registry comprises 915 IE patients, 366 (40%) with streptococcal IE. Based on phylogenetic relationship, streptococcal species were classified into seven main groups: Mitis, Bovis, Mutans, Anginosus, Salivarius, Pyogenic and Nutritionally Variant Streptococcus (NVS). Classification at species level was not possible in 51 patients, who were excluded. Complications and prognosis of streptococcal IE were compared between the subgroups, and at species level. Results We included 315 patients with streptococcal IE. Mean age was 63 (IQR 52–76) years, and most were men (67%). A total of 115 patients (37%) had a previous heart valve disease, 58 (18%) had a prosthetic valve, 22 (7%) had previously had IE and 29 (9%) had a cardiac electronic device. With 148 episodes (47%) the Mitis group was the most common cause of IE. Other frequent groups were the Pyogenic group and the Bovis group, accounting for 66 (21%) and 51 (16%) of the cases, respectively. Surgery was carried out in 55% (n=173) of all cases. Patients infected with S. pneumoniae or S. agalactiae had a significantly higher rate of surgery, 72.2% (n=13) and 71.9% (n=23) respectively, whereas the Bovis group had a significantly lower rate, 35.5% (n=18) (p=0.048). The aortic valve was infected in 137 patients (43.5%), mitral valve in 105 patients (33.3%) and both valves were infected in 53 patients (16.8%). Twenty patients (6.3%) had right-sided IE, including pacemaker lead IE. There was no significant difference between the species subgroups regarding type of infected valve. Embolization and osteitis were observed in 76 (24.1%) and 30 (9.5%) patients, respectively. There was no significant difference between the species groups, as was the case with mortality: 23 patients (7.3%) died in-hospital and the one-year mortality was 16% (n=50). Distribution of streptococcal IE Conclusion Species of the Mitis group were the most frequent Streptococci causing IE. Patients infected with S. pneumonia or S. agalactiae had significantly higher rate of surgery, and patients infected with S. bovis group had lower rate of surgery. There was no significant difference in rate of complications such as abscesses, embolization, osteitis or mortality between the streptococcal species.

Purpose: To determine the correlation between therapeutic effects of IVA treatment on typical AMD (tAMD), and polypoidal choroidal vasculopathy (PCV) and the history of hypertension, diabetes mellitus, smoking history and single nucleotide polymorphisms (SNPs).Methods: Prospective, interventional study. Subjects were assigned to 125 untreated patients with exudative AMD (tAMD: 58 patients, PCV: 67 patients, male: 91:34, mean age 73.4 years). Among the tAMD patients, there were 28 bimonthly injections 30 who received pro re nata (PRN) injections after three monthly injections. Among the PCV patients, 33 were treated with bimonthly injections and 34 received PRN injections after three monthly injections. Therapeutic effects were evaluated by best-corrected visual acuity (BCVA), central retinal thickness (CRT), subfoveal choroidal thickness (CCT), and exudative change after 3 months and 1 year from initial treatment, and also the history of hypertension, diabetes mellitus, smoking and five SNPs (rs10490924, rs800292, rs699947, rs1061170, rs13278062).Results: Improvements of BCVA, CRT were observed in all groups at 1 year after initial treatment. The one-yearchange in CRT showed significant improvement in nonsmokers than smokers in tAMD. The one-year change in CRT indicated a significant improvement in non-diabetic patients in PCV. There was more exudation at both 3 months and 1 year who had smoking history in tAMD. With respect to the rs1061170 mutation of tAMD, in the case with TT type, significant residual exudation was noted at both 3 and 12 months.Conclusions: The history of smoking and diabetes could be influence to IVA treatment for AMD.

Objectives: Lesions in the anterior segment of the vocal fold are sometimes difficult to access by means of conventional suspension microlaryngoscopy under general anaesthesia because of anatomical factors such as short, stout and inflexible necks, reduced jaw protrusion, and long incisors. Various techniques have recently been proposed for the management of inaccessible glottic lesions, most of which are performed under general anaesthesia. The use of flexible videoendoscopic surgery under topical anaesthesia in two cases of anterior glottic lesions that could not be treated by means of conventional suspension laryngoscopy is described.Study design: Case report.Methods: A flexible videobronchoscope with an instrument channel was inserted transnasally on an out-patient basis. While the examiner carried out the endoscopy, an assistant manoeuvred the biopsy forceps through the instrument channel, and removed the lesion.Results: Both patients underwent successful removal of an anterior glottic polyp, and the one-year follow-up evaluation revealed normal anatomy of the vocal folds and normal vocal function.Conclusions: Flexible videoendoscopic surgery under topical anaesthesia is a safe, simple and minimally invasive procedure that can be considered as an alternative to traditional endoscopic surgery for inaccessible anterior glottic lesions.

The relevance of isolated autoimmunity elevation in orthotopic liver transplantation (OLT) patients is unknown. Our aim was to analyse how serum autoantibodies change in time and to evaluate their clinical relevance in OLT patients. Patients were invited to provide samples to evaluate ANA, AMA, ASMA, and LKM at the time of enrolment (T0), after 6 months (T6), and after 12 months (T12). We included 114 patients in the study (76% males, median age 62.5 years), finding isolated elevation of at least one serum antibody in up to 80% of them. We described fluctuating positive autoantibodies in the one year of observation, with only 45.6% of patients positive for ANA and less than 2% positive for ASMA, at all three times. Isolated elevation of tissue antibodies was not related to gender, age, HCC at transplant, early rejection, cause of transplantation, immunotherapy taken, and age at the time of the study. We did not detect a higher prevalence of positive autoimmunity in patients with signs of liver injury. ANA and ASMA evaluation in patients with liver transplantation and no history of autoimmune disease has no clinical relevance, since it varies in time and is not related to any risk factors or liver injury. Routine autoimmunity evaluation should be avoided.

Study Objective: The objective of this study is to describe the maternal and perinatal outcome of conservative managementin PPROM. Design: Descriptive prospective study. Period: One year from August 2006 to August 2007. Setting: Maternal and child health(MCH) Centre PIMS Islamabad. Material and Methods: 50 patients between 28-36 weeks of gestation presenting with PPROM. Results:The mean age was 27+5.1 years, 14(28%) were having gestational age between 28to 32 weeks and 36 (72%) were between 33 to 36weeks of gestation. 34 (68.0%) of the mothers had no history of abortions while 10 (20.0%) had 1-2 abortions and 6 (12.0%) had 3 ormore abortions. Sixteen (32.0%) women had previous PRROM while 10 (20.0%) had previous history of preterm labor. Inversecorrelation was observed between latency period and gestational age. Among 14(28%) women with gestational ages between 28 to 32weeks 10 delivered within 48 hours and 4 after 48 hours. Among 36(72%) women with gestational ages between 33-36 weeks 31(62%)delivered in less than 48 hours and 5 (10 %) women delivered after 48 hours.14(28%) of the 50 babies were admitted in NICU withsepticemia, 7(14.0%) with RDS, hypoglycemia in 2(4.0%) and necrotizing enterocolitis in 3(6.0%). 3 neonates died from septicemia and2 from RDS. On first follow-up 34.0% mothers had infections and 8.0% had post-partum hemorrhage. Conclusions: Expectantmanagement till 36 weeks is a suitable option as gestational age at delivery and birth weight both affect neonatal survival and offer time toadminister corticosteroids to allow foetal lung maturity. Foetal deaths occurred due to septicaemia and RDS with direction co-relationshipwith low birth weight.

Background: Childhood poisoning covers the entire gamut from accidental ingestion in toddlers and preschool children to intentional overdosage in adolescents. To find the clinic- epidemiological profile of poisoning regarding age, sex, type of poison, manner of poisoning, common clinical features, duration between poisoning and presentation to hospital, duration of hospital stay, to find out the different agents involved duration of ICU stay, pre-referral treatment and treatment given.Methods: All children below 12 years of age admitted during the one-year study period with a history of poisoning were included. Animal bites, snake and scorpion envenomation, chronic poisoning, drug allergy was excluded. All children were examined, investigated and treated according to hospital policy. The outcome of poisoning was recorded.Results: There were 143 cases of children with poisoning admitted. Accidental poisoning constituted 88.1% cases (n126),7.7% (n11) was suicidal and the remaining 4.2%(n6) was homicidal. In most cases, poisoning was due to hydrocarbons followed by pesticides. kerosene oil was the most common substance followed by OPC.Conclusions: The highest incidence of poisoning was observed in children below 5 years of age and from the lower middle socio-economic group. Most of the poisons were household products and the most common nature of exposure was accidental in most of the cases, recovery was complete.

Background: Aortic arch calcification (AAC) is very common in hemodialysis patients and is associated with cardiovascular events and the incidence of arteriovenous fistula (AVF) failure. In order to predict the prognosis of patients, a study was conducted to determine the annual failure rate of AVF and its related factors. Methods: This cross-sectional study was performed on 145 patients with end-stage renal disease (ESRD) who were AVF candidates, visiting a referral center in Golestan province of Iran. After the insertion of intravenous arterial fistulas, posterior-anterior chest x-rays were captured, and the grafts were classified by a radiologist. Patients were followed for one year, and the rates of fistula failure (FF) and cardiovascular mortality were recorded. Finally, the data were entered into SPSS 19 software and analyzed by the Chi-square test. Results: Of 112 patients followed up for one year, 56.2% were men. During the one-year follow-up period, 5.3% of the patients developed arteriovenous FF, and this event was more common in men, but the difference was not statistically significant. The majority of the AVF candidates had a history of diabetes and hypertension, but no association was found between the one-year FF rate and these two diseases. Nearly 7.7% of the patients had grade III calcification, but no significant relationship was observed between the AAC grade and AVF failure rate. Conclusions: The rate of one-year FF was higher among ESRD patients with a history of chronic kidney diseases. Our results also demonstrated that the mortality rate is higher in patients with a high degree of AAC and patients with medical history (cardiovascular disease and diabetes).
