Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study).

AIM: Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. METHODS: The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. RESULTS: The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 µg/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. CONCLUSION: The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management.

Acute generalized exanthematous pustulosis due to ceftriaxone: Report of a pediatric case with recurrence after positive patch test.

Acute generalized exanthematous pustulosis (AGEP) is seen uncommonly in children and sometimes shows atypical clinical features in this population. Patch testing can be used effectively in children for the confirmation of the culprit drug in cases of multiple drug use. Here, we report a rare, pediatric case of ceftriaxone-induced AGEP confirmed by patch testing with subsequent recurrence of the skin eruption.

Ventriculoperitoneal shunt infections and re-infections in children: a multicentre retrospective study.

PURPOSE: Ventriculoperitoneal shunt (VPS) is the most common treatment modality for hydrocephalus. However, VPS infection is a common and serious complication with high rates of mortality and morbidity. The objective of this study was to investigate causative agents and the management of VPS infections and to identify risk factors for re-infection in children. MATERIALS AND METHODS: Retrospective, multicentre study on patients with VPS infection at paediatric and neurosurgery departments in four tertiary medical centres in Turkey between January 2011 and September 2014. RESULTS: A total of 290 patients with VPS infections were identified during the study period. The aetiology of hydrocephalus was congenital malformations in 190 patients (65.5%). The most common symptom of shunt infection was fever in 108 (37.2%) cases. At least one pathogen was identified in 148 VPS infections (51%). The most commonly isolated pathogen was coagulase-negative staphylococci, which grew in 63 cases (42.5%), followed by Pseudomonas aeruginosa in 22 cases (14.9%), Klebsiella pneumoniae in 15 cases (10.1%), and Staphylococcus aureus in 15 cases (10.1). The median duration of VPS infection was 2 months (range, 15 days to 60 months) after insertion of the shunt, with half (49.8%) occurring during the first month. VPS infection was treated by antibiotics and shunt removal in 211 cases (76.4%) and antibiotics alone without shunt removal in 65 patients (23.5%). Among the risk factors, CSF protein level greater than 100 mg/dL prior to VPS insertion was associated with a potential risk of re-infection (OR, 1.65; p =.01). CONCLUSION: High protein levels (>100 mg/dL) before the re-insertion of a VPS may be a risk factor for VPS re-infection.

The diagnostic value of soluble urokinase plasminogen activator receptor (suPAR) compared to C-reactive protein (CRP) and procalcitonin (PCT) in children with systemic inflammatory response syndrome (SIRS).

BACKGROUND: The aim of the present study was to determine the diagnostic and prognostic values of suPAR and to compare them to CRP and PCT in pediatric patients with systemic inflammatory response syndrome (SIRS). MATERIAL-METHODS: A prospective case-control study was performed.The study was performed in a tertiary university hospital which has a 649-bed capacity. Patients included 27 children with SIRS and 27 control subjects without any infection or immunosuppressive condition. Blood samples were obtained on the day of admission and on the 4-7th days of the hospital stay. RESULTS: The median (min-max) serum levels of suPAR obtained on the first day of the admission were 10.06 (2.7-57.46) and 2.22 (1.08-5.13) ng/Ml for the SIRS group and control group, respectively. The median serum levels of suPAR in the SIRS group was significantly higher than that in the control group (p < 0.05). The serum suPAR levels was significantly higher in nonsurvivors than in survivors in SIRS group (p < 0.05). In the SIRS group, the area under the receiver operating characteristics curve (AUCROC) for suPAR revealed an optimum cut-off value, sensitivity, specificity, NPV and PPV of 0.978, 3.8 ng/mL, 96%, 96%, 96%, and 96%, respectively. CONCLUSIONS: We conclude that suPAR does have diagnostic value in children with SIRS. Additionally, persistent high serum suPAR level predicts mortality in SIRS in children.

The diagnostic value of soluble urokinase plasminogen activator receptor compared with C-reactive protein and procalcitonin in children with febrile neutropenia.

The aim of the present study was to determine the diagnostic value of soluble urokinase plasminogen activator receptor (suPAR) in pediatric patients with febrile neutropenia. A prospective case-control study was performed. Patients included 29 children with febrile neutropenia (FN) and 27 control subjects without any infection or immunosuppressive condition. Blood samples were obtained on the day of admission and on the 4th to 7th days of the hospital stay. The median (minimum-maximum) serum levels of suPAR obtained on the first day of the admission were 2.08 (0.93-9.42) and 2.22 (1.08-5.13) ng/mL for the FN group and the control group, respectively. The median serum levels of suPAR in the FN and control groups were not significantly different (P = .053). The mean serum suPAR level was significantly higher in nonsurvivors than in survivors in the FN group (P < .05). In the FN group, the area under the receiver operating characteristics curve (AUCROC) for suPAR was 0.546, but no optimum cutoff value, sensitivity, specificity, negative predictive value (NPV), or positive predictive value (PPV) was obtained. We conclude that suPAR is not useful as a diagnostic biomarker in children with febrile neutropenia; however, persistent high serum suPAR level may predict mortality in FN in children.

Reduction of nosocomial infections in the intensive care unit using an electronic hand hygiene compliance monitoring system.

INTRODUCTION: Healthcare-associated infection is an important cause of mortality and morbidity worldwide. Well-regulated infection control and hand hygiene are the most effective methods for preventing healthcare-associated infections. This study evaluated and compared conventional hand hygiene observation and an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections. METHODOLOGY: This pre- and post-intervention study, employed an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections at a tertiary referral center. Healthcare-associated infection surveillance was recorded in an anesthesia and reanimation intensive care unit from April 2016 to August 2016. Hand-hygiene compliance was observed by conventional observation and an electronic recording and reminder system in two consecutive 2-month periods. healthcare-associated infections were calculated as incidence rate ratios. RESULTS: The rate of healthcare-associated infections in the electronic hand- hygiene recording and reminder system period was significantly decreased compared with that in the conventional hand-hygiene observation period (incidence rate ratio = 0.58; 95% confident interval = 0.33-0.98). Additionally, the rate of central line-associated bloodstream infections and the rate of ventilator-associated pneumonia were lower during the electronic hand hygiene recording and reminder system period (incidence rate ratio= 0.41; 95% confident interval = 0.11-1.30 and incidence rate ratio = 0.67; 95% confident interval = 0.30-1.45, respectively). CONCLUSIONS: After implementing the electronic hand hygiene recording and reminder system, we observed a significant decrease in healthcare-associated infections and invasive device-associated infections. These results were encouraging and suggested that electronic hand hygiene reminder and recording systems may reduce some types of healthcare-associated infections in healthcare settings.

Influenza A (H1N1)-associated severe complications; hemolytic uremic syndrome, myocarditis, acute necrotizing encephalopathy.

Influenza is a generally self-limited infection agent that only rarely causes severe complications. To increase awareness about its serious complications, we report three cases of influenza A (H1N1) infection complicated with hemolytic uremic syndrome, myocarditis and acute necrotizing encephalopathy. In all three cases, nasopharyngeal samples confirmed influenza A (H1N1) infection by antigen test and multiplex PCR detection. The first case, a 3-year-old girl, had respiratory distress, anemia, thrombocytopenia and renal failure at admission, and was diagnosed with hemolytic uremic syndrome. Supportive treatment and oseltamivir did not prevent the development of chronic renal failure. The second case, a 5-year-old girl admitted with lethargia and flu-like symtoms and was diagnosed with myocarditis and cardiogenic shock. Oseltamivir and supportive treatment including extra-corporeal membrane oxygenation (ECMO) failed. She died on the 3rd day of admission. The third case, a 21-month-old boy, presented with decreased level of consciousness and was diagnosed with acute necrotizing encephalopathy with the aid of cranial magnetic resonance imagining (MRI). He was discharged without any neurological sequelae three weeks after admission. It should be kept in mind that influenza virus does not always cause a self-limited flu. Multidisciplinary management, early diagnosis and antiviral treatment are critical for the disease and to prevent its life-threatening complications.

Lactococcus lactis spp lactis infection in infants with chronic diarrhea: two cases report and literature review in children.

Lactococcus lactis is a gram-positive, facultative anaerobic coccus that is occasionally isolated from human mucocutaneous surfaces such as the intestines. It is used in the dairy industry for milk acidification and is mostly nonpathogenic in immunocompetent humans, however a number of cases of infection with L. lactis have been reported in recent years. In this article, we describe two cases of infection due to L. lactis in patients with chronic diarrhea. The first case is a five-month-old boy who was operated on for volvulus on his first day of life and had ileostomy with subsequent diagnosis of chronic diarrhea and bacteremia due to L. Lactis. The second case is a six-month-old girl with the diagnosis of chronic diarrhea that developed after a catheter-related bloodstream infection. Both of the infections due to L. Lactis spp lactis were successfully treated with intravenous vancomycin therapy. Although Lactococcus species is mostly known as nonpathogenic, it should be kept in mind as a potential pathogen, especially in patients with gastrointestinal disorders.

Prevalence of Neisseria meningitidis carriage: a small-scale survey in Istanbul, Turkey.

INTRODUCTION: The human nasopharynx is the main reservoir of Neisseria meningitidis, and asymptomatic carriage is common. N. meningitidis one of the common causes of bacterial meningitis in Turkey, especially after the implementation of the national immunization program that includes conjugated pneumococcal and Haemophilus influenzae type b vaccines. The purpose of this study was to evaluate the prevalence of meningococcal carriage and determine the leading serogroup, which may help authorities to adapt appropriate meningococal vaccine into the national immunization programme. METHODOLOGY: The prevalence of oropharyngeal carriage of N. meningitidis in 1,000 healthy subjects, 0-79 years of age, was investigated. Oropharyngeal swabs were collected during an 18-month period. Samples obtained were inoculated onto Thayer-Martin agar. The API-NH test and VITEK-MS system were used for identification of colonies. Multiplex real-time polymerase chain reaction assay was used to determine serogroups with serogroup-specific genes. RESULTS: N. meningitidis was isolated from 6 of 1,000 subjects (0.6%). Meningoccocal carriers were between 21 and 40 years of age. All isolates were serogrouped as B, except one that did not survive on subculture. N. lactamica was isolated from 13 of 1,000 subjects (1.3%). CONCLUSIONS: Carriage rate of meningococci in our study was relatively low. However, we detected that serogroup B was the leading strain in meningococcal carriage in Istanbul; choosing an appropriate meningococcal vaccine containing serogroup B should therefore be considered. High absolute humidity throughout the year in Istanbul may explain the low prevalence of carriage in our study. This should be verified with a multicenter national survey.

Cutaneous Tuberculosis Occurring After a Skin Cut in a Child.

BACKGROUND: Tuberculosis is a common problem in Turkey, and cutaneous tuberculosis is a rare form of extrapulmonary tuberculosis. Herein, the authors describe a case of cutaneous tuberculosis (lupus vulgaris) occurring after contact with a sheep. CASE: A 15-year-old boy was admitted to Marmara University School of Medicine Pendik Training and Research Hospital (Istanbul, Turkey) with delayed wound healing on the left index finger and left axillary lymphadenopathy. His medical history was unremarkable except for a wound incurred when he slaughtered a sheep 3 months before. One month after this injury, the patient developed enlargement of the left axillary lymph node on the side of the wounded extremity, and the wound turned a dark black color. The biopsy specimens obtained from the wounded skin and lymph nodes showed granulomatous reaction, but acid-fast bacilli (AFB) could not be shown with Ehrlich-Ziehl Neelsen staining. The patient tested positive in an interferon-gamma release assay. Computerized tomography scans of the thorax were normal, and early morning gastric lavage specimen was negative for AFB. The wound and axillary lymphadenopathy disappeared after institution of anti-tuberculosis therapy. CONCLUSION: Tuberculosis infection must be considered in chronic skin lesions with granulomatous reaction occurring in countries with high prevalence of tuberculosis.

Healthcare-associated infections in a newly opened pediatric intensive care unit in Turkey: Results of four-year surveillance.

INTRODUCTION: Healthcare-associated infections (HAIs) are important causes of morbidity and mortality, especially in critically ill patients in intensive care units. The aim of this study was to assess the rate and distribution of HAIs, pathogens, and antimicrobial susceptibility patterns in a newly opened pediatric intensive care unit (PICU). METHODOLOGY: The infection control team detected and recorded HAI cases according to the Centers for Disease Control and Prevention's criteria in the PICU of Marmara University Pendik Training and Research Hospital over a four-year period following its opening. Laboratory-based HAIs surveillance was performed prospectively from 1 January 2011 to 30 November 2014. RESULTS: During the study period, 1,007 patients hospitalized in the PICU and 224 HAIs were identified. The overall HAI rate was 22.24%, and the incidence density was 20.71 per 1,000 patient-days. The most commonly observed HAIs were bloodstream infection (35.7%), pneumonia (21.4%), and urinary tract infection (20.5%), and the three most common HAI pathogens were Klebsiella spp. (19.4%), Pseudomonas aeruginosa (13.8%), and Acinetobacter baumanii (12%). Methicillin resistance was detected in 78% of coagulase-negative Staphylococcus. Presence of extended-spectrum beta-lactamases was determined in 45% and 54% of Klebsiella spp. strains and Escherichia coli isolates, respectively. CONCLUSIONS: Our rate of HAIs is higher than the mean rates reported in PICU studies from developed countries. Active surveillance studies of HAIs is an essential component of infection control, which may contribute to improving preventive strategies in developing countries.

Human Bite-induced Cellulitis Due to Streptococcus pyogenes.

The rate of infection after a human bite is 10%-30%. Streptococcus spp. are the most common pathogens that may cause serious infections, such as necrotizing fasciitis. The authors describe a 5-year-old girl admitted to the emergency room with cellulitis due to S. pyogenes after human bites. She presented with fever and pain in her left arm, and her medical history revealed a human bite by her cousin on the arm 3 days prior. The wound culture yielded S. pyogenes. She was successfully treated with intravenous ampicillin-sulbactam regimen. S. pyogenes may cause serious wound infections following human bites. In such cases, the patient should be closely followed. Chemoprophylaxis should be initiated in an appropriate clinical setting to prevent secondary bacterial infections. This case was first reported as cellulitis due to S. pyogenes after a human bite.

Cytomegalovirus Retinitis in an ALL Child during Maintenance Therapy Treated Successfully with Intravenous Ganciclovir.

Purpose. In here we described cytomegalovirus retinitis (CMVR) in 12-year-old male patient with acute lymphoblastic leukemia (ALL) who was on maintenance phase therapy. Methods. He was referred to our clinic for seeing of spots with the right eye for 3 days. At presentation, his best corrected visual acuity was 20/20 in the right eye and 20/20 in the left eye. Slit-lamp biomicroscopic examination of the anterior chamber of the left eye was within normal limits, whereas we observed 3+ anterior chamber cellular reaction in the right eye. On retinal examination, we found active retinitis lesions (cream-colored lesions associated with hemorrhages) and perivascular cuffing in the retinal periphery in the right eye. Left eye was normal. Results. On the basis of clinical picture, we made the diagnosis of CMVR in the right eye. Vitreous aspiration was performed and 23096 copies/mL of CMV DNA was detected by polymerase chain reaction (PCR) technique. The patient was successfully treated with intravenous ganciclovir for two weeks and discharged with oral valganciclovir prophylaxis. Conclusion. CMVR should be in mind in children with ALL on maintenance phase therapy even in those without hematopoietic stem cell transplantation. These patients can be treated successfully by intravenous ganciclovir alone.

Recurrent bacterial meningitis in a child with mondini dysplasia.

Mondini dysplasia, also known as Mondini malformation, is a developmental abnormality of the inner and middle ears that can cause hearing loss, cerebrospinal fluid (CSF) leakage, and recurrent bacterial meningitis (RBM), which is defined as two or more episodes of meningitis separated by a period of convalescence and the complete resolution of all signs and symptoms. An accurate diagnosis of the underlying pathology is crucial to prevent further episodes from occurring. Herein, we present a three-year-old boy with RBM and unilateral sensorineural hearing loss. During the evaluation to determine the etiology of the RBM, cystic malformation in the cochlea and vestibular dilatation consistent with Mondini dysplasia were detected via computerized tomography (CT) of the temporal bone.

Compliance of healthcare workers with hand hygiene practices in neonatal and pediatric intensive care units: overt observation.

Background. The objective of this study was to assess the compliance of hand hygiene (HH) of healthcare workers (HCWs) in the neonatal and pediatric intensive care unit in a tertiary university hospital in Istanbul. Methods. An observational study was conducted on the compliance of HH for the five World Health Organization (WHO) indications. HCWs were observed during routine patient care in day shift. The authors also measured the technique of HH through hand washing or hand hygiene with alcohol-based disinfectant. Results. A total of 704 HH opportunities were identified during the observation period. Overall compliance was 37.0% (261/704). Compliance differed by role: nurses (41.4%) and doctors (31.9%) [P = 0.02, OR: 1.504, CI 95%: 1.058-2.137]. HCWs were more likely to use soap and water (63.6%) compared to waterless-alcohol-based hand hygiene (36.3%) [P < 0.05]. Conclusion. Adherence to hand hygiene practice and use of alcohol-based disinfectant was found to be very low. Effective education programs that improve adherence to hand hygiene and use of disinfectants may be helpful to increase compliance.
