Monitoring of adenoviremia in pediatric patients undergoing hematopoietic stem cell transplantation: Is it alone sufficient to predict adenoviral disease?

BACKGROUND: We aimed to evaluate our pediatric HSCT recipients routinely monitored for adenoviremia and to determine the adequacy of this monitoring in predicting adenoviral disease (AD). METHODS: A retrospective cohort of patients who underwent allogeneic HSCT between January 2021 and August 2022, and routinely monitored for adenoviremia by real-time PCR was included in our survey. Demographic and clinical data of the patients were recorded. Incidence rates, risk factors, and mortality rates related to adenoviremia, and AD were analyzed. RESULTS: Among 104 HSCTs performed in 94 patients adenovirus (AdV) was revealed in 27 (26%) episodes and adenoviremia in 18 (17.3%) HSCT episodes. AD without adenoviremia developed in nine episodes (8.6%). Disseminated disease was significantly more frequently detected in episodes with adenoviremia (p = .008). GVHD was independent risk factor for AdV detection (OR: 8.6, 95% CI: 2.03-33.7, p = .001). Viremia developed within a shorter time interval after HSCT in isolated episodes of adenoviremia compared to those with concomitant AD (p = .006). Initial and peak viral loads were significantly higher in adenoviremia with AD (p < .001). Mortality was higher in the AdV-detected episodes (p < .001) than in the AdV-undetected episodes. AdV-related mortality was found to be 22.2%. Adenoviremia increased the risk of mortality (OR: 1.2, 95% CI: 0.22-1.33, p = .01). CONCLUSIONS: Adenoviremia monitoring is an important process in the detection of AD. Since some patients may develop AD without accompanying by adenoviremia, monitoring for AdV in blood samples should be supported with other monitoring methods in order to evaluate the probable involvement of different organs or systems.

Intravenous fosfomycin indications and treatment outcomes in pediatric usage: analysis from a single center in Turkey.

Current data on fosfomycin usage in children are limited. We present data on the clinical use of intravenous (IV) fosfomycin in children. Hospitalized patients who received ≥3 days of IV fosfomycin between April 2021 and March 2023 were analyzed retrospectively. Forty-three episodes of infection in 39 patients were evaluated. The mean age of the patients was 5.35 (10 days to 17.5 years) years, and 54% were male. Infections were hospital-acquired in 79% of the episodes. Indications for fosfomycin were urinary tract infection (35%), bacteremia (32.6%), catheter-related bloodstream infection (16.3%), soft tissue infection (4.7%), sepsis (4.7%), surgical site infection (2.3%), burn infection (2.3%), and pneumonia (2.3%). Klebsiella pneumoniae was identified in 46.5% of the episodes, and a pan-drug or extensive drug resistance was detected in 75% of them. Carbapenem was used before fosfomycin at significantly higher rates in K. pneumoniae episodes (P = .006). Most (88.5%) patients received fosfomycin as a combination therapy. Culture negativity was achieved in 80% of episodes within a median treatment period of 3 (2-22) days, which was significantly shorter in K. pneumoniae episodes (P < .001). Treatment-related side effects were seen in 9.3% of the episodes. Side effects were significant after 3 weeks of treatment (P = .013). The unresponsivity rate to fosfomycin was 23.3%. Nine (21%) of the patients who were followed up in the intensive care units mainly died because of sepsis (56%). IV fosfomycin is an effective agent in treating severe pediatric infections caused by resistant microorganisms. Fosfomycin can be used in various indications and is generally safe for children.

Antibiotic associated diarrhea in outpatient pediatric antibiotic therapy.

BACKGROUND: Antibiotic-associated diarrhea is one of the most frequent side effects of antimicrobial therapy. We assessed the epidemiological data of antibiotic-associated diarrhea in pediatric patients in our region. METHODS: The prospective multi-center study included pediatric patients who were initiated an oral antibiotic course in outpatient clinics and followed in a well-established surveillance system. This follow-up system constituded inclusion of patient by the primary physician, supply of family follow-up charts to the family, passing the demographics and clinical information of patient to the Primary Investigator Centre, and a close telephone follow-up of patients for a period of eight weeks by the Primary Investigator Centre. RESULTS: A result of 758 cases were recruited in the analysis which had a frequency of 10.4% antibiotic-associated diarrhea. Among the cases treated with amoxicillin-clavulanate 10.4%, and cephalosporins 14.4% presented with antibiotic-associated diarrhea. In the analysis of antibiotic-associated diarrhea occurrence according to different geographical regions of Turkey, antibiotic-associated diarrhea episodes differed significantly (p = 0.014), particularly higher in The Eastern Anatolia and Southeastern Anatolia. Though most commonly encountered with cephalosporin use, antibiotic-associated diarrhea is not a frequent side effect. CONCLUSION: This study on pediatric antibiotic-associated diarrhea displayed epidemiological data and the differences geographically in our region.

Oxidative stress and decreased Nrf2 level in pediatric patients with COVID-19.

The aim of this study was to investigate the change in nuclear factor erythroid 2-related factor (Nrf2), which plays a critical role in cytoprotection against oxidative stress, in pediatric patients with coronavirus disease 2019 (COVID-19) infection positivity, and to evaluate the relationship between Nrf2 and oxidative balance. The study included 40 children with confirmed COVID-19 infection and 35 healthy children. The groups were compared in respect of Nrf2, total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI), in addition to clinical findings of fever, cough, shortness of breath, contact history, and demographic data of age and gender. The mean Nrf2 values and TAS levels were determined to be statistically significantly low (p < 0.001) and the TOS level and OSI were statistically significantly high in the children with COVID-19 compared to the control group. A significant positive correlation was determined between Nrf2 and TAS (p < 0.01); as the Nrf2 value increased, so the TAS value increased. A significant negative correlation was determined between Nrf2 and TOS and OSI (p < 0.01); as the Nrf2 value increased, there was determined to be a significant decrease in the TOS and OSI values. COVID-19 infection in pediatric patients causes a decrease in the Nrf2 level. By causing a decrease in the TAS level and an increase in the TOS and OSI levels, the decrease in Nrf2 may explain the tissue damage which can be caused by COVID-19.

Treatment of pediatric cutaneous leishmaniasis with liposomal amphotericin B.

The use of liposomal amphotericin B (L-AmB) in the treatment of cutaneous leishmaniasis (CL) is increasing. However, few data are available regarding the efficacy and safety of L-AmB in pediatric CL patients. Our aim in this study is to evaluate the efficacy and safety of L-AmB in pediatric CL patients. Pediatric patients admitted to a tertiary training and research hospital in a hyperendemic region for CL between January 2019 and May 2021 and receiving L-AmB therapy for CL were included in this retrospective study. L-AmB treatment was administered as 3 mg/kg for 5 consecutive days and on the 10th day, in a total of 6 doses (18 mg/kg total dose). A total of 52 pediatric patients who received L-AmB therapy for CL were included in the study. In the follow-up 3 months after L-AmB treatment, 16 (31%) patients showed complete clinical recovery, while treatment failure was detected in 36 (69%) patients. In conclusion, considering the low treatment success rate in our study, we think that the L-AmB dose used in our study is not an appropriate treatment option for the treatment of pediatric CL patients. However, we think that prospective studies with a large number of patients treated with higher doses of L-AmB and in whom the causative agents of CL were determined are needed.

Differences and similarities of multisystem inflammatory syndrome in children, Kawasaki disease and macrophage activating syndrome due to systemic juvenile idiopathic arthritis: a comparative study.

To compare the clinical and laboratory findings of multisystem inflammatory syndrome in children (MIS-C), patients with Kawasaki disease (KD) and with macrophage activating syndrome due to systemic juvenile idiopathic arthritis (sJIA-MAS) on real-life data. Patients diagnosed with MIS-C, KD, and sJIA-MAS from 12 different centers in Turkey who were followed for at least 6 months were included in the study. Demographic, clinical, and laboratory findings of all patients were analyzed. A total of 154 MIS-C, 59 KD, and 31 sJIA-MAS patients were included. The median age of patients with MIS-C were higher than those with KD while lower than those with sJIA-MAS (8.2, 3, 12 years, respectively). Myalgia (39.6%), cardiac (50.6%), gastrointestinal (72.7%), and neurological (22.1%) involvements were more common in patients with MIS-C compared to others. MIS-C patients had lower levels of lymphocyte (950 vs 1700 cells/µl) and thrombocyte (173,000 vs 355,000 cells/µl) counts and higher pro-BNP (1108 vs 55 pg/ml) levels than KD. Ferritin levels were higher in patients with MIS-C compared to patients with KD while they were lower than patients with sJIA-MAS (440, 170, 10,442 ng/ml, respectively). Patients with MIS-C had a shorter duration of hospitalization than sJIA-MAS (p = 0.02) while they required intensive care unit admission more frequently (55 vs 8 patients, p < 0.001). The median MAS/sJIA score of MIS-C patients was - 1.64 (- 5.23 to 9.68) and the median MAS/sJIA score of sJIA-MAS patients was -2.81 ([- 3.79] to [- 1.27]). MIS-C patients displayed certain differences in clinical and laboratory features when compared to KD and sJIA-MAS. Definition of the differences and similarities between MIS-C and the other intense inflammatory syndromes of childhood such as KD and MAS will help the clinicians while making timely diagnosis.

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.

Anxiety in Paediatric Patients Diagnosed with COVID-19 and the Affecting Factors.

OBJECTIVE: Children may be greatly affected by events that increase stress in individuals in general and are reported as the vulnerable groups during the coronavirus disease-19 (COVID-19) pandemic. But most of the studies in the literature investigating the mental effects of the pandemic on children were conducted with healthy children and limited study has evaluated the effect on children diagnosed with COVID-19. The aim of this study is to determine the anxiety level in paediatric patients diagnosed with COVID-19 and the affecting factors. METHODS: This descriptive study was conducted with 292 children aged 8-18 years who were diagnosed with COVID-19. Data were collected using the Descriptive Characteristics Questionnaire and the Screen for Child Anxiety Related Emotional Disorders (SCARED). Interviews were held by phone. RESULTS: Males were 51.4% of participants, the mean age was 16.04 ± 1.93. 84.1% of them had a chronic disease; the transmission source was family/relatives/friends for 41.1%. By social isolation, 49.3% were affected and 33.2% were affected by disease symptoms the most in this process. The most common symptoms were headache (61.6%), and asthenia (59.9%). Mean anxiety scale score was 25.5 ± 14.37. The effect of gender, number of symptoms and transmission source on anxiety score was significant (p < 0.05). CONCLUSION: Paediatric patients diagnosed with COVID-19 were found to have high anxiety levels. It is recommended to re-evaluate the duration of children's social participation and support the management of COVID-19 symptoms that affect their anxiety level.

Do parents vaccinated against COVID-19 protect their children from hospitalization due to COVID-19?

OBJECTIVE: This study aimed to determine whether parental vaccination against coronavirus disease 2019 (COVID-19) prevents hospitalization of COVID-19-infected children. METHODS: This study was based on data obtained from the records of pediatric patients that were followed up for virologically proven COVID-19 infection between August and October 2021, during which time the delta variant was dominant in Turkey and the children were isolating at home. RESULTS: There were 151 patients in the inpatient group and 218 in the outpatient group; the mean age was 172.5 and 145.5 months in the groups, respectively. The rates of obesity (22.5% and 6.4%, respectively, p < 0.001) and neurological-neurodevelopmental disorders (8.6% and 1.4%, respectively, p < 0.001) were significantly higher in the inpatient group than in the outpatient group. Of the outpatients' parents, 67.4% (n = 147) were fully vaccinated vs. 38.4% (n = 58) in the inpatient group. In all, 39.7% (n = 60) of the inpatients' parents were unvaccinated vs. 18.3% (n = 40) in the outpatient group. There was a significant correlation between the vaccination status and the patient groups (p < 0.001); it was determined that the COVID-19 infection would be mild in children if both parents were fully vaccinated. When both parents were fully vaccinated against COVID-19, the hospitalization rate decreased and the outpatient follow-up rate increased. CONCLUSION: Having both parents fully vaccinated against COVID-19 can indirectly protect their subsequently infected children from hospitalization and the long-term effects of infection. Nonetheless, more comprehensive research on delta and non-delta variants is needed.

Evaluation of inflammatory parameters in patients with cutaneous leishmaniasis.

Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease characterized by various skin lesions that can cause deformities when healed. Our aim in this study is to show the utility of parameters such as neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and mean thrombocyte volume (MTV) as auxiliary laboratory methods in CL patients. About 107 patients who were admitted to our dermatological and venereal diseases outpatient clinic between January 2018 and January 2019 and were diagnosed with CL by microscopic examination and 74 healthy individuals were included in the study. There were no significant differences between the patient and control group in terms of neutrophil counts, leukocyte counts, platelet counts, and NLR values (P values: .271, .053, .263, and .459, respectively). When the TLR and MTV values of patients with CL and those of the healthy controls were compared, it was found that TLR and MTV values were statistically higher in patients with CL (P values of .010 and .044, respectively). Based on these data, NLR was not considered to be a suitable parameter for demonstrating inflammation in CL patients, but TLR and MTV were held to be an appropriate parameter for demonstrating inflammation in CL patients. In addition, we think that the increase in MTV and TLR, can be used as an auxiliary laboratory test in the diagnosis of CL disease.

Use of radiological tests in COVID-19 positive child cases: Is chest computed tomography necessary?

OBJECTIVE: This study aimed to correlate the radiographic findings of the coronavirus disease 2019 (COVID-19) positive children with their clinical and laboratory findings and discuss the frequency and necessity of chest computed tomography (CT) used for the radiological imaging in paediatric patients with COVID-19 infection. MATERIALS AND METHODS: Sixty-nine paediatric inpatient cases were retrospectively analysed using their clinical, laboratory and imaging features. The National Public Health Guide was used in the diagnosis and treatment of paediatric patients. COVID-19 infections for all patients were confirmed by the COVID-19 nucleic acid test using a pharyngeal swab. RESULTS: The median age of the patients was 11 years [3-15]. The most common clinical symptoms were fever (40.6%) and cough (33.3%). When the laboratory findings of patients were examined, the median white blood cell (WBC) count was 5.8/mm3 (4.8-8.05/mm3 ), median lymphocyte count was 2.3/mm3 (1.7-3.55/mm3 ) and median C-reactive protein (CRP) level was 2.3/mm3 (1-2.1/mm3 ). All patients had chest radiographs (CRXs), while only 44.9% of the patients underwent a chest CT. The 8.7% of CXRs and 12.8% of chest CT findings were found as pathological. Ground-glass opacity was the most frequent finding. In the tomography group, the count of lymphocytes was lower, and creatine kinase (CK) and lactate dehydrogenase (LDH) levels were significantly higher. The patients with pathological tomography findings demonstrated no statistically significant difference in lymphocyte count and CK and LDH levels; however, their CRP value was significantly higher. CONCLUSION: In this study, it is emphasised that chest CT should be requested by considering the underlying diseases and severity of clinical findings in paediatric patients. In this way, unnecessary chest CT could be prevented in the paediatric population.

Atypical and unusual morphological variants of cutaneous leishmaniasis.

OBJECTIVE: Cutaneous leishmaniasis (CL) is a skin disease characterised by prolonged nodulo-ulcerative lesions of the skin that heals with atrophic scar. Clinical features of CL vary depending on the type of parasite and host immune resistance. The aim of this study was to investigate the clinical features of atypical and unusual morphological variants of CL patients diagnosed in our clinic. MATERIALS AND METHODS: In this prospective study, 27 CL patients with atypical clinical features among 486 patients admitted to our clinic between July 2018 and September 2019 and diagnosed as CL by slit-skin smear examination or histopathological examination were included. RESULTS: Of 27 patients, 15 (55.5%) were male and 12 (44.5%) were female. The mean age of the patients was 25.8 ± 7.62 years. Seven (25.9%) patients had lupoid lesions, five (18.6%) patients had eczematoid lesions, four (14.8%) patients had lip lesions, three (11.1%) patients had erysipelas-like lesions, two (7.4%) patients had eyelid lesions, two (7.4%) patients had sporotrichoid lesions, two (7.4%) patients had verrucous lesions, one (3.7%) patient had psoriasiform lesion and one (3.7%) patient had paronychial lesion. CONCLUSION: In conclusion, rare clinical forms of CL are presented in this study. It should be kept in mind that CL may have very different clinical features and should be considered in the differential diagnosis of eczema, psoriasis, erysipelas, sporotrichosis, paronychia and verrucous lesions.

[Frequency of Influenza, Influenza Types and Influenza Vaccine Use in Hospitalized Children with Influenza-Like Symptoms]. / Grip Benzeri Sikayetler ile Hastaneye Yatirilan Çocuklarda Influenza Sikligi, Influenza Tipleri ve Influenza Asisi Kullanimi.

Influenza is an important cause of respiratory illness in children and is still an important cause of morbidity and mortality in children. The influenza virus subtypes determine the prevalence of the epidemic and pandemic influenza, the hospitalization and mortality rates in children each year. Surveillance of the circulation of different influenza virus strains is important in ensuring a good strain con-cordance for the composition of the annual influenza vaccine. The Global Influenza Hospital Surveillance Network® (GIHSN) is an international institution in which tertiary hospitals from many countries participate and where epidemiological surveillance of influenza disease is conducted. Six centers from Turkey participated in the study organized by GIHSN during the influenza season 2016 2017. The aim of this study was to demonstrate the frequency of influenza, virus types, clinical characteristics and vaccination rates in children admitted to our hospital with influenza-like symptoms in the influenza season 2016-2017. Informed consents were obtained from patients. 217 pediatric patients were screened with in the 24th and 48th hours of the hospitalization. Then a nasal/nasopharyngeal swab were collected from 184 patients who met the inclusion criteria. Real-time reverse-transcription polymerase chain reaction (rRT-PCR) was used to obtain laboratory results. Influenza virus, influenza virus subtypes were studied by rRT-PCR. The 83.3% of the patients with positive influenza was under 5 years of age. The rate of influenza positivity was 16.3% (n= 30 patients). Influenza A (H3N2) was the predominant strain in children. The 70% of isolates were influenza A (H3N2) and the 30% were influenza B (Yamagata). There were no case of influenza A (H1N1) or influenza B (Victoria). In 30% of cases with influenza positivity, there was an underlying disease. The most prevalent of them were neuromuscular disease followed by cardiovascular disease and asthma. Tobacco exposure was 86.6% in influenza positive cases. The empirical oseltamivir prescription rate was 28.2%. The vaccination rate of the influenza vaccine was very low (1.6%). The out of 3 patients with influenza positivity were admitted to pediatric intensive care unit, and 2 of them required mechanical ventilation. None of these patients required extracorpereal membrane oxygenation and did not die. Our results highlight the importance of surveillance for influenza and in particular, influenza vaccination rates of groups with risk for morbidity and mortality, such as children, need to be increased.

Underlying Diseases and Causative Microorganisms of Recurrent Pneumonia in Children: A 13-Year Study in a University Hospital.

Pneumonia is a significant cause of death for children, particularly those in developing countries. The records of children who were hospitalized because of pneumonia between January 2003 and December 2015 were retrospectively reviewed, and patients who met the recurrent pneumonia criteria were included in this study. During this 13-year period, 1395 patients were hospitalized with pneumonia; of these, 129 (9.2%) met the criteria for recurrent pneumonia. Underlying diseases were detected in 95 (73.6%) patients, with aspiration syndrome (21.7%) being the most common. Rhinovirus (30.5%), adenovirus (17.2%) and respiratory syncytial virus (13.9%) were the most frequent infectious agents. These results demonstrate that underlying diseases can cause recurrent pneumonia in children. Viruses are also commonly seen in recurrent pneumonia. Appropriate treatments should be chosen based on an analysis of the underlying disease, the patient's clinical condition and the laboratory and radiological data.

Bloodstream infections in pediatric hematology/oncology patients: Six years' experience of a single center in Turkey

Background/aim: Bloodstream infections are the major cause of morbidity, increased cost, prolonged hospitalization, and mortality in pediatric patients. Identifying the predominant microorganisms and antimicrobial susceptibilities in centers helps to select effective empirical antimicrobials which leads to positive clinical outcomes. We aimed to identify the causative microorganisms and their antimicrobial susceptibilities in patients with bloodstream infections. Materials and methods: Data belonging to patients with hematological and/or oncological diseases admitted to our hospital with fever between January 2010 and November 2015 were analyzed. Results: In total, 71 patients who had 111 bloodstream infection episodes were included. Responsible pathogens were detected as follows: 35.1% gram-positive microorganisms, 60.5% gram-negative bacteria, and 4.4% fungi. The most common causative gram-negative pathogen was Escherichia coli and the most commonly isolated gram-positive microorganism was coagulase-negative staphylococci. Conclusion: Gram-negative microorganisms were predominant pathogens in bloodstream infections. Escherichia coli and coagulase-negative staphylococci were the most commonly isolated responsible pathogens. Beta-lactam/lactamase inhibitors were suitable for empirical treatment. However, in critical cases, colistin could have been used for empirical treatment until the culture results were available. Routine glycopeptide use was not required. By identifying the causative microorganisms and their antimicrobial resistance patterns, it will be possible to obtain positive clinical results.

Radiographic findings of adenoviral pneumonia in children.

OBJECTIVE: Adenovirus pneumonia is a common cause of community-acquired pneumonia in children and can mimic bacterial pneumonia, but there are few publications on its radiographic features. This study has evaluated the chest radiography findings of community-acquired adenovirus pneumonia in children. The frequency of radiological findings mimicking bacterial pneumonia was investigated. The clinical features of patients with adenovirus pneumonia possessing radiological findings mimicking bacterial pneumonia were also evaluated. MATERIALS AND METHODS: The chest radiographs of patients diagnosed with adenovirus pneumonia were retrospectively reviewed. The chest radiographs were interpreted independently by a pediatric infectious disease specialist and a pediatric radiologist. Chest radiography findings mimicking bacterial pneumonia (bacterial-like) were specified as consolidation +/- pleural effusion. Other findings on chest radiography or a completely normal chest X-ray were specified as findings that were compatible with "typical viral pneumonia". RESULTS: A total of 1407 patients were positive for adenovirus with respiratory multiplex PCR. The 219 patients who met the study criteria were included in the study. Chest radiographs were normal in 58 (26.5 %) patients. The chest radiograph findings mimicked bacterial pneumonia in 41 (18.7 %) patients. CONCLUSION: Adenovirus pneumonia occurs predominantly in children aged five years and younger, as with other viral pneumonias. The radiographic findings in adenovirus pneumonia are predominantly those seen in viral pneumonia. Increasing age and positivity for only adenovirus without other viruses on respiratory multiplex PCR were associated with the chest radiograph being more likely to be "bacterial-like". Adenovirus may lead to lobar/segmental consolidation at a rate that is not very rare.

Catheter-related Infections in Pediatric Patients Due to a Rare Pathogen: Herbaspirillum huttiense.

BACKGROUND: Herbaspirillum species are nonfermenting, aerobic, helical or curved, Gram-negative bacteria belonging to the class Betaproteobacteria, order Burkholderiales. To date, only a few studies have reported on the epidemiology, clinical symptoms, antibiotic susceptibility profiles, treatment and outcomes of Herbaspirillum huttiense -related infections in pediatric patients. METHODS: The aim of this study was to present 3 years of H.huntiense data, antibiotic susceptibility profiles, systemic antibiotics and antibiotic lock therapy (ALT) options and clinical outcomes. RESULTS: Fourteen episodes of infection in 12 patients were included in this retrospective study. The patients had a male/female ratio of 1:1 and a median age of 160.5 months (range, 3-198 months). Catheter-related bloodstream infection (CRBSI) was detected in 11 patients. Only 1 patient developed catheter-related infective endocarditis. The patient's catheter was removed, and she was successfully treated with systemic antibiotics for 4 weeks. Systemic antibiotics were used in all infections related to H. huttiense . In septic, critically ill patients, the catheter was removed, and systemic antibiotics were started. Port catheters were removed in 5 patients. ALT was performed in clinically stable patients. ALT using amikacin was administered to 6 patients through the port catheter. Two patients had a 2nd attack. After the 2nd ALT treatment, 1 patient cured, and the catheter of the other patient was removed due to persistent microbial growth in cultures. Antimicrobial susceptibility testing of the reported isolates showed susceptibility to meropenem (90%), ceftazidime (87%) and piperacillin/tazobactam (65%), with 92% resistance to colistin. CONCLUSION: H. huttiense is an emerging pathogen in CRBSI. Piperacillin/tazobactam, ceftazidime and meropenem appear to be good therapeutic options for the treatment of H. huttiense infections. ALT and systemic antibiotics can be used in H. huttiense -CRBSI to sterilize and preserve the central venous catheter.

Generalized tetanus: a pediatric case report and literature review.

Pediatric tetanus is a rare and forgotten disease in countries with high childhood tetanus toxoid vaccination rates. Therefore, the clinical manifestations, treatment and management of this potentially life-threatening disease are not well known. With a literature review and discussion of tetanus management in pediatric patients, we describe a clinical course of a rare and fatal but vaccine-preventable disease, the generalized tetanus, in an adolescent who was successfully treated.

Clinical Management of a Pandrug-Resistant OXA-48 Klebsiella pneumoniae Infection in the Pediatric Intensive Care Unit.

Background: Carbapenem-resistant Klebsiella pneumoniae (CRKP) is one of the serious forms of health care-associated infection. Pan-drug resistant (PDR) CRKP infections can cause severe infections. Mortality and treatment costs in the pediatric intensive care unit (PICU) are high. This study aims to share our experience regarding the treatment of oxacillinase (OXA)-48-positive PDR-CRKP infection in our 20-bed tertiary PICU with isolated rooms and 1 nurse for every 2-3 patients. Methods: Patient demographic characteristics, underlying diseases, previous infections, source of infection PDR-CRKP, treatment modalities, measures used, and outcomes were recorded. Findings: Eleven patients (eight men and three women) were found to have PDR OXA-48-positive CRKP. Because of the simultaneous detection of PDR-CRKP in three patients and the rapid spread of the disease, it was classified as a clinical outbreak, and strict infection control measures were taken. Combination therapy with double carbapenemase (meropenem and imipenem), amikacin, colistin, and tigecycline was used for treatment. The mean duration of treatment and isolation was 15.7 and 65.4 days, respectively. No treatment-related complication was observed, only one patient died, and the mortality rate was 9%. Conclusions: This severe clinical outbreak can be successfully treated with effective treatment with combined antibiotics and strict adherence to infection control measures.
