Introduction: We aimed to present the risk factors, clinical and laboratory findings, treatment management, and risk factors for morbidity and mortality of infective endocarditis (IE) as well as to relate experiences at our center. Method: We retrospectively analyzed data of 47 episodes in 45 patients diagnosed with definite/possible IE according to the modified Duke criteria between May 2000 and March 2018. Results: The mean age of all patients at the time of diagnosis was 7.6±4.7 years (range: 2.4 months to 16 years). The most common symptoms and findings were fever (89.3%), leukocytosis (80.8%), splenomegaly (70.2%), and a new heart murmur or changing of pre-existing murmur (68%). Streptococcus viridans (19.1%), Staphylococcus aureus (14.8%), and coagulase-negative Staphylococci (10.6%) were the most commonly isolated agents. IE-related complications developed in 27.6% of the patients and the mortality rate was 14.8%. Conclusion: We found that congenital heart disease remains a significant risk factor for IE. The highest risk groups included operated patients who had conduits in the pulmonary position and unoperated patients with a large ventricular septal defect. Surgical intervention was required in most of the patients. Mortality rate was high, especially in patients infected with S. aureus, although the time between the onset of the first symptom and diagnosis was short. Patients with fever and a high risk of IE should be carefully examined for IE, and evaluation in favor of IE until proven otherwise will be more accurate. In high-risk patients with prolonged fever, IE should be considered in the differential diagnosis. [ABSTRACT FROM AUTHOR]

Kawasaki disease (KD) is an idiopathic vasculitis syndrome which is largely seen in children under five years of age. It is the most common vasculitis encountered in childhood secondary to Henoch-Schönlein. Although it has a good prognosis with treatment, can lead to death from coronary artery aneurysm. Thus early diagnosis and treatment play a crucial role in prognosis of disease. Varying clinical signs and absence of definitive diagnostic laboratory findings pose a challenge for early diagnosis and treatment. Cases with fever lasting more than five days should alarm the physician as incomplete cases may be encountered. Serial echocardiographic examination must be performed in such cases regarding the cardiac complications. Our first patient is a five years-old male who has been treated for parapharyngeal phlegmon. He was consulted to our unit as his fever has been lasting for five days despite treatment and finally diagnosed as KD. Second patient is an eleven years-old male who was diagnosed as KD due to his fever lasting for ten days, peeling of the skin on the hands, photophobia and positive echocardiographic findings. We want to emphasize the importance of considering the diagnosis of atypical KD in two cases of long lasting fever. [ABSTRACT FROM AUTHOR]

The aim of this study was to determine the effects of adjuvant immunoglobulin M (IgM)-enriched intravenous immunoglobulin (IVIG) therapy on mortality rate, hematological variables and length of hospital stay in newborn infants with blood culture-proven sepsis. Demographic and clinical features and outcome measures of 63 newborn infants with blood culture-proven sepsis were documented retrospectively from the medical records. The patients were divided into two groups according to their treatment history. The patients in Group 1 received antibiotic therapy only and the patients in Group 2 received both antibiotic and adjuvant IgMenriched IVIG. The study revealed that mortality rates were 28.1% and 12.9% in Group 1 and Group 2, respectively. The mortality rate was lower in Group 2, but the difference between the two groups was not statistically significant (p=0.21). Coagulase-negative Staphylococcus was the most common type of bacteria isolated from the blood culture in both groups. When changing laboratory results were compared between the two groups, hemoglobin, leukocyte count and C-reactive protein levels were different during the first three days of antibiotic treatment. Our study revealed that if diagnosed at an early stage and treated aggressively with appropriate and effective antibiotics, adjuvant IgM-enriched IVIG treatment has no additional benefits in neonatal sepsis.
