[PMID: 37782350 DOI: 10.1007/s00431-023-05207-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 09/09/2023] [Accepted: 09/15/2023] [Indexed: 10/03/2023]
Abstract
PURPOSE Due to its link with the 2019 coronavirus, the multisystem inflammatory syndrome in children (MISC) has garnered considerable international interest. The aim of this study, in which MISC patients were evaluated multicenter, and the data of the third period of the Turk-MISC study group, to compare the clinical and laboratory characteristics and outcomes of MISC patients who did and did not require admission to an intensive care unit (ICU). METHODS This retrospective multicenter observational study was carried out between June 11, 2021, and January 01, 2022. The demographics, complaints, laboratory results, system involvements, and outcomes of the patients were documented. RESULTS A total of 601 patients were enrolled; 157 patients (26.1%) required hospitalization in the intensive care unit (ICU). Median age was 8 years (interquartile range (IQR) 4.5-11.3 years. The proportion of Kawasaki disease-like features in the ICU group was significantly higher than in the non-ICU group (56.1% vs. 43.2% p = 0.006). The ICU group had considerably lower counts of both lymphocytes and platelets (lymphocyte count 900 vs. 1280 cells × μL, platelet count 153 vs. 212 cells × 103/ μL, all for p< 0.001). C-reactive protein, procalcitonin, and ferritin levels were significantly higher in the ICU group (CRP 164 vs. 129 mg/L, procalcitonin 9.2 vs. 2.2 μg/L, ferritin 644 vs. 334 μg/L, all for p< 0.001). Being between ages 5-12 and older than 12 increased the likelihood of hospitalization in the ICU by four [95% confidence intervals (CI)1.971-8.627] and six times (95% CI 2.575-14.654), respectively, compared to being between the ages 0-5. A one-unit increase in log D-dimer (µg/L) and log troponin (ng/L) was also demonstrated to increase the need for intensive care by 1.8 (95% CI 1.079-3.233) and 1.4 times (95% CI 1.133-1.789), respectively. Conclusion: By comparing this study to our other studies, we found that the median age of MISC patients has been rising. Patients requiring an ICU stay had considerably higher levels of procalcitonin, CRP, and ferritin but significantly lower levels of lymphocyte and thrombocyte. In particular, high levels of procalcitonin in the serum might serve as a valuable laboratory marker for anticipating the need for intensive care. WHAT IS KNOWN • Lymphopenia and thrombocytopenia were an independent predictor factors in patients with MISC who needed to stay in intensive care unit. • The possibility of the need to stay in the intensive care unit in patients with MISC who had Kawasaki disease-like findings was controversial compared with those who did not. WHAT IS NEW • A one-unit increase log D dimer and log troponin was demonstrated to require for intensive care unit by 1.8 and 1.4 times, respectively. • Serum procalcitonin levels had the best performance to predict stay in the intensive care unit stay.

Evaluation of T-cell subsets in pregnant women infected with SARS-CoV-2. Int Immunopharmacol 2023; 124:110798. [PMID: 37633234 DOI: 10.1016/j.intimp.2023.110798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 08/10/2023] [Accepted: 08/11/2023] [Indexed: 08/28/2023]
Abstract
OBJECTIVE Immune responses to SARS-CoV-2 are the main cause of tissue damage in coronavirus disease 2019. However, the pathophysiological mechanism of the disease has not been fully elucidated. The aim of this study was to examine T cell subsets of pregnant women infected with SARS-CoV-2 and evaluate the relationship between the possible differences in trimesters and clinical findings of the disease. MATERIALS AND METHODS Fifty-six pregnant patients with SARS-CoV-2 and 61 healthy pregnant controls were included in the study. T cell subsets were analyzed by flow cytometry. RESULTS The CD3+ total T cell (p = 0.006 and p = 0.027) of pregnant patients infected with SARS-CoV-2 in second and third trimesters was found to be lower than in the control group. CD3+CD4+ helper T cell (p = 0.035), Treg (p = 0.001), and Treg/Th17 ratio (p = 0.001) were found to be lower in the third trimester patients infected with SARS-CoV-2 than in the controls. Significant decreases were observed only in the Treg (p = 0.001) and Treg/Th17 ratio (p = 0.001) in the first trimester patients infected with SARS-CoV-2 compared to the controls. When trimesters were compared in terms of T subsets, no difference was found (p > 0.05). CONCLUSION The CD3+ total T cell (p = 0.001), CD3+CD4+ helper T cell (p = 0.011), Treg (p = 0.001), and Treg/Th17 ratio (p = 0.001) were found to be lower in pregnant women infected with SARS-CoV-2. This difference was associated with the development of pneumonia but not with adverse pregnancy outcomes.

Abstract
OBJECTIVE Thermal therapy has existed for thousands of years and dates back to ancient civilizations such as the Finns, Romans, ancient Chinese, American Indians, and Egyptians. Sun therapy is a form of natural Far Infrared Rays (FIR) thermal therapy. Far infrared rays are invisible rays with the longest wavelength of natural sunlight. However, sunbathing should only be done in moderation, as sunlight contains ultraviolet rays that can burn and damage the skin. More than 30 million people in Asia, Europe, and Australia receive Far Infrared Therapy with FIR lamps. They emit 2-25-micron wavebands. We aimed to investigate whether FIR therapy that uses a similar waveband improves sinusitis symptoms. MATERIALS AND METHODS This study was conducted on 10 New Zealand rabbits of both sexes, 7-8 months old, with an average weight of 1.8-2.4 kg. They were divided into four study groups. Sinusitis was induced in rabbits by blocking the sinus ostium, whereas some were left as control. Far infrared treatment with an infra-sin device was given with or without antibiotics. Mucosal samples were evaluated microscopically regarding epithelial eruption, epithelial vacuolization, interstitial edema, vascular congestion, leukocyte infiltration, and mucosal thickening. RESULTS We found clinical and histopathological improvements in rabbits with sinusitis on the right side of the nose, to which we applied FIR treatment with the device Infra-Sin. CONCLUSIONS Our findings in this animal study led us to conclude that it would be beneficial to study the effects of FIR treatment on people with allergic rhinitis and sinusitis and to identify the optimal dosing, treatment duration, and intensity. To add to our findings, looking into whether FIR therapy can be used as an alternative to antibiotic treatment for human sinusitis is essential.

Antibiotic associated diarrhea in outpatient pediatric antibiotic therapy. BMC Pediatr 2023; 23:121. [PMID: 36932373 PMCID: PMC10024443 DOI: 10.1186/s12887-023-03939-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Accepted: 03/02/2023] [Indexed: 03/19/2023] Open
Abstract
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.

Abstract
Abstract
Aim
Right ventricular (RV) dysfunction is an important cause of graft failure after heart transplantation (HTx) and a challenge for echocardiographic evaluation. We sought to evaluate the accuracy of the most novel echocardiographic tools for the assessment of RV remodelling and function in asymptomatic HTx recipients with and without rejection.
Methods
All patients underwent right heart catheterization with biopsy, cardiac magnetic resonance (CMR) and echocardiography in a row within the same day while fasting, irrespective of symptoms, as part of institutional follow up protocol dedicated to HTx recipients. Invasively measured systolic pulmonary artery pressure was used to calculate RV myocardial work index (MWI) from strain-pressure loops by using the custom software (EchoPAC BT204, Horten, Norway). Event timings were determined from pulmonic and tricuspid valve opening and closures. With the aim to generate full bull's eye map by automated function imaging, we computed RV LS data from the apical 4-chamber view 3 times, from 3 consecutive cycles substituting apical LV views. Other indices of RV function were measured according to the EACVI 2015 recommendations for chamber quantification. RV volumes and ejection fraction (EF) were quantified by CMR. Echocardiographic measurements were compared with CMR derived RV EF and biopsy findings as the reference for microstructural changes. We also evaluated by echocardiography organ donors as healthy controls.
Results
Sixty-one fully matching studies (echo, CMR, catheter, biopsy) were analyzed. Tricuspid systolic annular velocity (S'), peak systolic excursion (TAPSE) and longitudinal strain (LS) were significantly lower in healthy HTx recipients as compared to controls (p<0.001 for all). Whereas, RV volumes, EF and fractional area change (FAC) were not different between HTx recipients and healthy controls (Figure 1, EDV:end-diastolic volume). In the overall HTx recipients, only FAC (r=0.51, p<0.001) but not S', TAPSE, LS or MWI correlated with CMR derived EF. Biopsy defined subclinical rejections however were nicely mirrored by LS, and MWI (Figure 2), whereas other indices failed to reflect microstructural changes. In addition, MWI had higher accuracy than LS to discriminate biopsy findings. RV volumes, EF, FAC as well as TAPSE, S' were insensitive to subclinical myocardial damage.
Conclusion
RV adaptation in healthy HTx recipients is characterized by decreased longitudinal function but preserved overall RVFAC, EF, and volumes. MWI seems to be more reliable than other echocardiographic parameters to track subclinical RV myocardial damage due to rejection, while the RV EF remains preserved.

T1 mapping of the right ventricle in heart transplant recipients: how does it correlate with endomyocardial biopsy findings? Eur Heart J 2022.

Abstract
Abstract
Aim
Noninvasive detection of cardiac allograft rejection is highly desirable. We sought to assess how right ventricular (RV) T1 mapping correlates with endomyocardial biopsy findings.
Methods
All patients underwent right heart catheterization with biopsy and cardiac magnetic resonance (CMR) irrespective of symptoms, as part of the institutional registry protocol dedicated to heart transplant (HTx) recipients. CMR studies were performed using a 1.5 T scanner and analyses by using a commercially available software (CMR42, Circle CVI, Calgary, Canada). Endocardial and epicardial borders were drawn on end-systolic and end-diastolic phases for ventricular function analysis. For T1 measurements, region of interests located at the RV free-wall were drawn manually on midventricular short-axis slices avoiding blood pool and epicardial fat. Extracellular volume (ECV) was calculated as ECV = (1 − hematocrit) × (ΔR1 myocardium/ΔR blood), where R1 = 1/T1. Late gadolinium enhancement (LGE) images were also obtained using a phase-sensitive inversion recovery segmented gradient echo sequence. Hyperenhancement was assessed semi-quantitatively as segmental (2–3 cm) or diffuse (>3 cm). Allograft rejection was determined based on the severity of inflammatory infiltrates and myocyte damage on pathological specimens according to the standardized International Society for Heart and Lung Transplantation (ISHLT) nomenclature.
Results
In all, 61 paired studies were evaluated. None of the patients had heart failure symptoms. We defined 3 subgroups: Group I; never rejected (n=23), group II; biopsy remarkable for rejection (n=19) and group III; history of past rejection(s) (n=19). RV volumes and ejection fraction (EF) did not differ between the groups. However, rejections were nicely mirrored by T1 time and particularly by ECV. Of note, T1 time and ECV improved but not completely normalized after resolution of rejection. Overall, T1 time (cut off 1060ms) and ECV (cut off 35%) were sensitive (84%, both) and had high negative predictive values (88% and 87%, respectively) but not specific (43% and 52% respectively) for discriminating rejection related subclinical RV damage. Their specificity slightly improved to 52 and 61% respectively, if patients with previous rejection were excluded (Figure 1). LGE did not discriminate rejection.
Conclusion
RV volumes and EF are insensitive to detect allograft rejection. Native T1 time and ECV of the RV, as a means of extracellular expansion, likely reflect interstitial fibrosis, oedema, and inflammation that are typical for, but not limited to allograft rejection. Hence, these parameters can help to exclude rejection but have limited standalone value for making the nonivasive diagnosis due to their low specificity. These results cannot be extrapolated to the left ventricle.

Abstract
INTRODUCTION COVID-19-related anosmia is a remarkable and disease-specific finding. With this multicenter cohort study, we aimed to determine the prevalence of anosmia in pediatric cases with COVID-19 from Turkey and make an objective assessment with a smell awareness questionnaire. MATERIAL AND METHODS This multicenter prospective cohort study was conducted with pediatric infection clinics in 37 centers in 19 different cities of Turkey between October 2020 and March 2021. The symptoms of 10.157 COVID-19 cases 10-18 years old were examined. Age, gender, other accompanying symptoms, and clinical severity of the disease of cases with anosmia and ageusia included in the study were recorded. The cases were interviewed for the smell awareness questionnaire at admission and one month after the illness. RESULTS Anosmia was present in 12.5% (1.266/10.157) of COVID-19 cases 10-18 years of age. The complete records of 1053 patients followed during the study period were analyzed. The most common symptoms accompanying symptoms with anosmia were ageusia in 885 (84%) cases, fatigue in 534 cases (50.7%), and cough in 466 cases (44.3%). Anosmia was recorded as the only symptom in 84 (8%) of the cases. One month later, it was determined that anosmia persisted in 88 (8.4%) cases. In the smell awareness questionnaire, the score at admission was higher than the score one month later (P < 0.001). DISCUSSION With this study, we have provided the examination of a large case series across Turkey. Anosmia and ageusia are specific symptoms seen in cases of COVID-19. With the detection of these symptoms, it should be aimed to isolate COVID-19 cases in the early period and reduce the spread of the infection. Such studies are important because the course of COVID-19 in children differs from adults and there is limited data on the prevalence of anosmia.

Abstract
OBJECTIVE Respiratory syncytial virus (RSV) is one of the most prevalent causes of lower respiratory tract infection (LRTI). The primary objective of this study is to provide the risk modelling of confirmed RSV infection in children who were born preterm at 29 to 35 weeks of gestational age and presented with LRTI. STUDY DESIGN This prospective, multicenter study was performed between October 2015 and March 2017. Premature infants born with gestational age between 29 and 35 weeks that were ≤2 years of age at the beginning of the RSV season and admitted to the hospital with clinical findings of LRTI during the season were included. RSV-positive and -negative infants were compared in terms of demographic features, risk factors, and requirement of hospitalization. RESULTS RSV positive group was lower than RSV negative group and ratio of ≤3 months age at admission was significant higher in RSV (+) group. RSV-positive infants were found to be significantly born during or 3 months prior to RSV season. The rate and duration of hospitalization and need for mechanical ventilation were significantly higher in RSV positive infants. The rate and duration of hospitalization in RSV positive patients was related to the chronological age. CONCLUSION This study showed that preterm infants with RSV-associated LRTI significantly needed more hospitalization, intensive care admission, and mechanical ventilation. In addition need of hospitalization and duration of hospitalization were significant higher in ≤3 months of age. Therefore, we suggest the importance of palivizumab prophylaxis in infants ≤ 3 months chronological age, especially during the RSV season.

Abstract
Objectives: The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children. Methods: A retrospective study was conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined. Results: There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (n = 582) and females constituted 49.7% (n = 574). The median age of the confirmed cases was 10.75 years (4.5-14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1-3 years of age (9.3%), 148 were 3-6 years of age (12.8%), 298 were 6-12 years of age (25.8%), 233 were 12-15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (n = 583) for a median of 2 days (IQR: 1-3 days). Fever was median at 38.4°C (38.0-38.7°C). The second most common symptom was cough (n = 543, 46.9%). The other common symptoms were sore throat (n = 143, 12.4%), myalgia (n = 141, 12.2%), dyspnea (n = 118, 10.2%), diarrhea (n = 112, 9.7%), stomachache (n = 71, 6.1%), and nasal discharge (n = 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (p < 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (p = 0.38), but the need for intensive care was higher in patients who had an underlying condition (p < 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma). Conclusions: To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution.

Abstract
Background Nephron-sparing surgery (NSS) is currently the recommended treatment modality for selected renal tumors. The prognostic significance of positive surgical margin (PSM) and surgical margin width (SMW) after NSS is controversial. Aim To evaluate the effect of PSM and SMW on cancer-specific survival (CSS) in patients who underwent NSS. Materials and Methods The pathological samples of 142 patients who underwent NSS were reviewed. Patients were divided into two groups with PSM and negative surgical margin (NSM), and after that those with PSM were divided into two groups according to SMW as those with 0.1-2 mm and those >2 mm. CSS was calculated using Kaplan-Meier method. Cox regression analysis was used to adjust the clinicopathologic variables. A P value < 0.05 was considered statistically significant. Results Local recurrence rate and distant metastasis rate were higher in patients with PSMs than those with NSMs (P = 0.018 and P = 0.039, respectively). However, there was no significant difference between the two groups in terms of CSS. In the group with SMW 0.1-2 mm, the tumor diameter was longer (P = 0.018), enucleation number was higher (P = 0.026), and local recurrence was higher (P = 0.034) than the group with SMW > 2 mm. There was no significant difference between the two groups in terms of CSS. Conclusion In patients who underwent NSS, PSMs and SMWs have a negative effect on local recurrence but have no significant effect on CSS.

Abstract
A 75-year-old woman presented with an 18-month history of severe, slowly worsening dysphonia. She was a smoker and known to have multiple benign cystic thyroid lesions. She reported no associated symptoms and other medical and social history was unremarkable. Fibreoptic nasendoscopy revealed a right-sided supraglottic cyst appearing to arise from the right false vocal cord. Further bedside examination was unremarkable. She underwent microlaryngoscopy and biopsy which showed a cyst originating from the right anterior ventricle, successfully removed without rupture using cold steel. Formal histopathology revealed a 14×10×7 mm unilocular, completely excised cyst lined by oncocytic epithelium and composed of columnar cells with darkly stained nuclei and abundant granular, eosinophilic cytoplasm. Three weeks postoperatively the patient's voice had returned to normal. To date, 11 months postoperatively, there is no evidence of recurrence, and she will continue long-term follow-up.

Abstract
PURPOSE To evaluate the vascular hemodynamic changes that can be detected with color Doppler imaging (CDI) in diagnosis, differential diagnosis and prognosis of uveitis with different etiologies including Behçet's disease. METHODS Four groups consisting of healthy volunteers, uveitis patients with different etiologies and Behçet's disease patients with and without ocular involvement were examined by CDI. Central retinal artery (CRA), posterior ciliary artery (PCA), ophthalmic artery (OA) and central retinal vein (CRV) flow velocities and vascular resistances were measured prospectively by a radiologist blinded to the presence and etiology of uveitis. RESULTS The peak systolic and end-diastolic velocities in CRA and PCA in Behçet's disease with ocular involvement were significantly lower than all other groups (p < 0.001). Peak systolic and end-diastolic velocities in CRA were lower than the control group in Behçet's disease patients without ocular involvement (p < 0.001) but there were no differences in PCA and OA flow velocity (p > 0.05). In the uveitis group, CRA and CRV flow velocities were significantly lower than in the control group (p < 0.001). CONCLUSIONS According to our results, uveitis in Behçet's disease is associated with significant reductions of CRA and PCA flow velocities when compared with other types of uveitis and healthy subjects. In cases without ocular involvement, CRA flow velocities were lower than the control group, but there were no real differences in the PCA and OA values. This suggests that vasculitic involvement of PCA is more specific to Behçet's disease and occurs later in the course of the disease. The results also suggest that it may be possible to detect and follow hemodynamic changes in Behçet's disease with CDI before clinical findings of ocular involvement become evident.

Abstract
PURPOSE To report the optical coherence tomography (OCT) findings in a 35-year-old man with acute inferior branch retinal artery occlusion. METHODS OCT findings in acute branch retinal artery occlusion were evaluated. RESULTS OCT disclosed diffuse thickening of the neurosensory retina in the inferior perifoveolar area. Increased reflectivity was noted in the inner retinal layers rom the surface of the retina to the photoreceptor layers. Decreased reflectivity was observed from the photoreceptor layers and the retinal pigment epithelium secondary to the shadowing effect. Foveolar depression, photoreceptor layer in the fovae, and retinal pigment epithelium underneath the fovea were normal. OCT findings in the superior perifoveolar area were also normal. CONCLUSIONS In the retinal artery occlusion, denaturation and breakdown of the normally transparent intracellular protein and an increase in the intracellular fluid cause ischemic whitening of the retina. Otherwise there is no retinal thickening secondary to the accumulation of serous fluid escaping from retinal capillaries into the extracellular space. The OCT findings support these descriptions.

Abstract
PURPOSE To report the results of intravitreal triamcinolone acetonide in two eyes of a patient with Vogt-Koyanagi-Harada syndrome. METHODS A 24-year-old woman with Vogt-Koyanagi-Harada syndrome was treated with a single 4-mg dose of intravitreal injection of triamcinolone acetonide in both eyes. RESULTS On the seventh day after injection, visual acuity improved from 20/50 to 20/20 in the right eye and from 20/100 to 20/32 in the left. One month after injection, visual acuity was 20/20 in the right eye and 20/32 in the left, and fluorescein angiography showed that serous detachment had almost completely resorbed. The ocular examination remained stable during the 8-month follow-up period. CONCLUSIONS In this study, a prompt improvement in the clinical picture of a patient with Vogt-Koyanagi-Harada syndrome after intravitreal triamcinolone acetonide injection was described. The results suggest that intravitreal triamcinolone acetonide injection may be an additional tool in the treatment of Vogt-Koyanagi-Harada syndrome.

Abstract
Purpose To determine macular sensitivity and fixation characteristics in eyes with central serous chorioretinopathy (CSC) using fundus-related microperimetry. Methods The authors reviewed 19 eyes with serous elevation within the central 10° due to CSC and 15 normal healthy eyes that had undergone fundus-related microperimetry. The macular sensitivity was measured using the fundus-related microperimeter, MP-1. The best-corrected visual acuity (BCVA), mean retinal sensitivity in the central 10° (central microperimetry, cMP-1) and in the paracentral 10° to 20° (paracentral microperimetry, pMP-1), and fixation stability and location were determined and compared with that of control eyes. Results Eyes with CSC showed significantly lower logMAR BCVA (p<0.001), cMP-1, and pMP-1 sensitivity than control eyes (p<0.001, p<0.01, respectively). Eyes with CSC were not significantly different in fixation location (p=1.00) or fixation stability than control eyes (p=0.45). Fixation location was predominantly central in all eyes with CSC; fixation was stable in 17 (89%) and relatively unstable in 2 (11%). Conclusions Eyes with CSC showed significantly lower retinal sensitivity not only at the central but also in the paracentral area. Even with decreased BCVA and retinal sensitivity, our patients showed central and stable fixation in their affected eyes.

Abstract
AIM We evaluated the short-term effect of repeated pain exposure on the pain responses of newborn infants using different pain assessment methods, as this area had been under-researched. METHODS We compared 20 term, large for gestational age infants and 40 term, appropriate for gestational age controls. All had undergone a heel stick for a newborn screening test just before discharge, but the larger babies had also undergone at least other five painful stimuli prior to that. A pulse oximeter and a skin conductance algesimeter (SCA) were connected to the babies during the heel prick, and video recordings were made. Crying time, the Neonatal Infant Pain Scale (NIPS), heart rate, peripheral oxygen saturation (SpO2 ) and SCA measurements were compared within and between the groups. RESULTS After the heel prick, the crying time (p = 0.021) and NIPS (p = 0.013) scores were significantly higher in the study group and the SpO2 levels were significantly lower (p = 0.009), but the heart rate (p = 0.981) was not significantly different between the groups. SCA measurements did not differ significantly between the groups. CONCLUSION Babies who received more painful stimuli during the first few days of life showed greater pain responses during a subsequent heel prick.

Abstract
UNLABELLED Peritonitis is a serious problem in children receiving peritoneal dialysis. Campylobacter jejuni is an unusual cause of peritonitis. A 10-year-old boy who had end stage renal failure due to atypical hemolytic uremic syndrome was admitted to our hospital with abdominal pain and fever. Peritoneal dialysis fluid was cloudy and microscopic examination showed abundant leukocytes. Intraperitoneal cefepime treatment was started. Campylobacter jejuni was isolated from peritoneal dialysis fluid culture and oral clarithromycin was added to the treatment. At the end of therapy, peritoneal fluid culture was negative. To our knowledge, C. jejuni peritonitis was not reported in children previously. CONCLUSION Although C. jejuni peritonitis is rarely encountered in children, it should be considered as an etiologic factor for peritonitis.

Abstract
Pelvic osteomyelitis is a rare infection. Ilium, ischium, pubis and acetabulum are commonly affected sites. Pelvic radiography, pelvic magnetic resonance and scintigraphy are useful imaging techniques for diagnosis. However, diagnoses should be confirmed with bone biopsy from the lesion. Sometimes diagnosis is delayed because of deep localization of infection site. Here in, we report a 15-year-old girl with left groin pain who was diagnosed as pelvic osteomyelitis one month after initial symptoms. Patient was successfully treated with antibiotics for 8 weeks. In conclusion, although pelvic osteomyelitis is an unusual infection in childhood, it should be considered as differential diagnoses of pain in groin, hips, thigh, abdomen and spine. If diagnosis is suspicious, empiric treatment should be started quickly, because it will be possible to achieve satisfactory clinical results with effective treatment.

Abstract
Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture. Extremity magnetic resonance imaging showed tissue defect in right foot, edema-inflammation and contrast enhancement. Intravenous sulbactam-ampicillin and oral amoxicillin and clavulanic acid were given for 6 weeks. In follow-up, clinical symptoms recovered without curettage. In conclusion; calcaneous osteomyelitis should be considered in the differential diagnosis of swelling on heel in neonates who have been applied to invasive procedures as Guthrie test sample.

Abstract
WHAT IS KNOWN AND OBJECTIVE Genetic variations in drug-metabolizing enzyme genes change drug pharmacokinetics and response. CYP2C19 is a clinically important enzyme that metabolizes citalopram (CIT). The objective of this study was to determine CYP2C19 genetic polymorphisms and to evaluate the impact of these polymorphisms on the metabolism of citalopram in a sample of the Turkish population. We also assessed *17 polymorphism in healthy subjects in this population. METHODS The CYP2C19 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism method (209 healthy individuals and 50 patients for CIT metabolism), and the plasma concentrations of CIT and demethylcitalopram (DCIT) were quantified by high-performance liquid chromatography. RESULTS AND DISCUSSION The CYP2C19*1 and *17 allele frequencies for the patient group and the healthy group were 71·0%, 18·0% and 81·1%, 18·9%, respectively. There was no significant difference between the two groups (P > 0·05). The mean plasma concentrations and the mean dose-corrected (C/D) plasma levels of DCIT were significantly higher in patients with the CYP2C19*1/*1 genotype compared to patients with CYP2C19*1/*2 and CYP2C19*2/*2 genotypes (P < 0·05). Furthermore, the mean metabolic ratio (MR, CIT/DCIT) was also significantly higher in the CYP2C19*1/*2 + CYP2C19*2/*2 genotypes (P < 0·05). On the other hand, plasma CIT, DCIT concentrations and M/R value in the CYP2C19*1/*1 genotypes were no different to those of the CYP2C19*1/*17 genotypes (P > 0·05). WHAT IS NEW AND CONCLUSION Our data suggest that CYP2C19*17 polymorphism does not have a significant effect on CIT metabolism. In contrast CYP2C19*2 polymorphism has a prominent role and is likely to contribute to interindividual variability in CIT metabolism in vivo at therapeutic doses.

Abstract
BACKGROUND Many studies have tried to be establish a pathogenic role for human herpesvirus-6 and -8 (HHV-6, HHV-8) in malignant diseases, but whether these viruses plays a role in these pathologies remains unclear. HHV-6 and HHV-8 seropositivity were shown in a healthy population. There is no published data in Turkey about seroprevalence of these viruses. We aimed to determine the seroprevalence of HHV-6 and HHV-8 in pediatric cancer patients and to compare with healthy Turkish children's viral seroprevalence. PATIENTS AND METHODS Ninety-three pediatric cancer patients and 43 age-matched healthy children were included in the study. All sera were screened for antibodies to HHV-6 and HHV-8 by ELISA. RESULTS HHV-8 immunoglobulin G (IgG) was positive in 3.3% of lymphoma patients, in 4.8% of acute lymphoblastic leukemia (ALL) patients, in 4.8% of retinoblastoma patients and in 7% of healthy children. There was no significant difference in HHV-8 seroprevelance between these groups. HHV-6 seroprevalence was 81% in ALL patients, 70% in lymphoma group, 81% in retinoblastoma patients and 69.8% in healthy children. Although there was no significant difference in HHV-6 prevalence between healthy children and pediatric cancer patients, HHV-6 seropositivity tended to be higher in retinoblastoma patients under age of 4 years (odds ratio: 2.925). CONCLUSION HHV-6 seroprevalence was higher than HHV-8 seropositivity in our study. Viral studies related HHV-6 seroprevelance in retinoblastoma patients would be useful to clarify if there is any etiological association between HHV-6 and retinoblastoma.

Abstract
We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.

Abstract
AIM High incidence of difficult or failed intubation in obstetric patients is still a major problem to challenge anaesthesiologists. Although the probability of difficult intubation is impossible to predict preoperatively, some simple, practical bedside tests may help. This study used five simple tests in an attempt to better evaluate airway changes in pregnant women before and after delivery. MATERIALS AND METHODS Pregnant women from the ASA I-II group who were planning to undergo a normal vaginal delivery were evaluated as to the possibility of experiencing difficult intubation. Mallampati scores, thyromental distance, sternomental distance, mouth opening, and the degree of neck extension were recorded just before delivery and 24 h after delivery. RESULTS Significant differences were seen in the pre- and post-delivery measurements (p < 0.05). Before delivery, Mallampati scores I, II, III, IV were 35, 24, 2, 0, respectively, and 24 h after delivery became 46, 15, 0, 0, respectively. CONCLUSIONS Within 24 h after delivery, Mallampati scores changed in one-third (n 21, 36.6%) of the patients. Significant differences between the two measurements of thyromental and sternomental distances, mouth opening, and the degree of neck extension confirm difficult airway management in pregnant women.

Abstract
AIM Hydrogen sulphide (H2S), recently considered the third endogenous gaseous transmitter capable of modulating many physiological processes. The purpose of this study was to analyze the morphometric and histopathological changes associated with experimental periodontitis in rats in response to systemic administration of H2S METHODS: Forty-eight Wistar rats were divided into six experimental groups: non-ligated (NL) group; ligature only (LO) group; systemic administration of NaHS (H2S donor drug) alone (NaHS) group (14 µmol/kg body weight per day); and ligature placed and systemic administration of three different doses of NaHS groups (14, 28 and 70 µmol/kg/day) (L-NaHS-14, L-NaHS-28 and L-NaHS-70, respectively). Silk ligatures were placed at the gingival margin of lower first molars. Changes in alveolar bone levels were clinically measured and tissues were histopathologically examined. RESULTS At the end of 15 days alveolar bone loss significantly higher in the entire ligature (LO and L-NaHS-14, -28 and -70) groups compared to the unligated groups (P<0.05) but there were no statistically significant differences in alveolar bone loss between LO and L-NaHS groups. Osteoclast number was significantly lower in L-NaHS-70 group than those of L-NaHS-14 and L-NaHS-28 groups (P<0.05). The osteoblastic activity of the L-NaHS-14 and -70 groups were significantly higher than those of the other groups (P<0.05). CONCLUSION The findings of this study suggested that NaHS, when administered systemically with three different doses, did not prevent or increase alveolar bone loss in the rat model.

Abstract
A 2.5-month-old boy admitted to our hospital with irritability, poor feeding and fever of 12 hours duration. On physical examination, he was febrile and extremely irritable. Initial whole blood count revealed a hemoglobin level of 10.1 g/dl, white blood count of 17,800/mm3 and platelet count of 454,000/mm3. Erythrocyte sedimentation rate was 80 mm/h and C-reactive protein was 3.96 mg/dl. Biochemical examinations of serum, urinalysis, chest X-ray, and analysis of cerebrospinal fluid (CSF) were normal. He was started on intravenous ampicillin and ceftriaxone empirically for provisional occult bacteremia. His blood, urine and CSF cultures were negative. On the 7th day of the treatment, there were no additional symptoms or findings other than fever. Echocardiography revealed aneurysms in both the left and right coronary arteries. Intravenous immunoglobulin (IVIG) and per oral aspirin were administered, and the fever resolved after IVIG infusion. Two years later, the echocardiography showed disappearing of the saccular aneurysm on the right coronary artery, but the dilatation of the left coronary artery was persisting. In conclusion, incomplete Kawasaki disease should always be included in the differential diagnosis of an infant with persistent fever, especially one younger than three months of age, when the conventional work-up fails to reveal the underlying cause.

Abstract
AIM The purpose of this study was to analyze histologically the effect of ozone therapy in combination with autogenous bone graft on bone healing in rat calvaria. METHODS Critical size defects were created in calvaria of 27 male Wistar rats. The animals were divided into three groups of nine animals each: autogenous bone graft group (n = 9); autogenous bone graft with ozone therapy group (80%, 30 s 3 d for 2 wk, n = 9); non-treatment (control) group (n = 9). Animals were killed after 8 wk. Histomorphometric assessments, using image analysis software, and histological analyses were performed. Primary outcome was total bone area. Secondary outcomes (osteoblast number, new bone formation) were also measured. RESULTS Histomorphometrically, the total bone area in the autogenous bone graft with ozone therapy group (9.3 ± 2.2) were significantly higher than that of the autogenous bone graft group (5.1 ± 1.8) (p < 0.05). Also, the ozone therapy group significantly increased the percentage of total bone area compared to the autogenous bone graft group (p < 0.05). The osteoblast number significantly increased in the autogenous bone graft with the ozone therapy group (58 ± 12.3) compared to the autogenous bone graft group (9.3 ± 3.5) (p < 0.05). Also, it was observed that autogenous bone graft with ozone therapy group showed significant new bone formation when compared to the autogenous bone graft group (p < 0.05). CONCLUSION Ozone therapy enhances new bone formation by autogenous bone graft in the rat calvarial defect model.

Abstract
Brucellosis is a public health problem in most countries in the Mediterranean. Involvement of the central nervous system is seen in 4-13% of patients with brucellosis. A 13-year-old girl was admitted because of gait disturbance, diplopia, and dizziness. Her complaints began about 1.5 years ago. The second symptomatic episode repeated about three months ago and the third two months ago. In total, attacks repeated 3 times over 1.5 years. The magnetic resonance imaging (MRI) and the clinical features mimicked multiple sclerosis. The patient was given pulse steroid treatments. After steroid treatment, her gait disturbance and diplopia improved over the short term. Following positive developments, her symptoms recurred. The tests were repeated; the MRI showed increasingly high signal abnormalities, and Brucella melitensis was grown in cerebrospinal fluid. The patient was started on an oral combination of rifampin, doxycycline, and ciprofloxacin. MRI findings improved markedly after nine months of treatment. Although neurobrucellosis is associated rarely with demyelination in adults, this finding has not been reported previously in children or adolescents. Additionally, this case is the first in terms of involvement of the corpus callosum in neurobrucellosis. In this article, we present an unusual case of neurobrucellosis.

Abstract
BACKGROUND AND OBJECTIVE The purpose of this study was to evaluate the morphometric and histopathological changes associated with experimental periodontitis in diabetic rats in response to systemic administration of N-acetylcysteine (NAC), a sulfhydryl-containing thiol antioxidant. MATERIAL AND METHODS Sixty Wistar rats were divided into six experimental groups: nonligated (NL) group; ligature-only (L) group; streptozotocin-only (STZ) group; STZ and ligature (STZ + L) group; and systemic administration of NAC and ligature (70 and 100 mg/kg body weight per day, respectively) (NAC70 and NAC100 groups). Diabetes mellitus was induced by 60 mg/kg of streptozotocin. Silk ligatures were placed at the gingival margin of the lower first molars of the mandibular quadrant. The study duration was 30 d and the animals were killed at the end of this period. Changes in alveolar bone levels were clinically measured and tissues were histopathologically examined to assess the differences among the study groups. RESULTS At the end of the 30-d study period, alveolar bone loss was significantly higher in the STZ + L group compared with the other groups (p < 0.05). Also, alveolar bone loss in all the NAC groups was significantly lower than in the STZ + L and L groups (p < 0.05). The osteoblastic activity in the NAC100 group was significantly higher than in the other groups (p < 0.05). CONCLUSION Within the limits of this study, it can be suggested that NAC, when administered systemically, prevents alveolar bone loss in the diabetic rat model.

The epidemiology and economic impact of varicella-related hospitalizations in Turkey from 2008 to 2010: a nationwide survey during the pre-vaccine era (VARICOMP study). Eur J Pediatr 2012; 171:817-25. [PMID: 22170238 DOI: 10.1007/s00431-011-1650-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2011] [Accepted: 11/30/2011] [Indexed: 11/30/2022]
Abstract
Varicella can cause complications that are potentially serious and require hospitalization. Our current understanding of the causes and incidence of varicella-related hospitalization in Turkey is limited and sufficiently accurate epidemiological and economical information is lacking. The aim of this study was to estimate the annual incidence of varicella-related hospitalizations, describe the complications, and estimate the annual mortality and cost of varicella in children. VARICOMP is a multi-center study that was performed to provide epidemiological and economic data on hospitalization for varicella in children between 0 and 15 years of age from October 2008 to September 2010 in Turkey. According to medical records from 27 health care centers in 14 cities (representing 49.3% of the childhood population in Turkey), 824 children (73% previously healthy) were hospitalized for varicella over the 2-year period. Most cases occurred in the spring and early summer months. Most cases were in children under 5 years of age, and 29.5% were in children under 1 year of age. The estimated incidence of varicella-related hospitalization was 5.29-6.89 per 100,000 in all children between 0-15 years of age in Turkey, 21.7 to 28 per 100,000 children under 1 year of age, 9.8-13.8 per 100,000 children under 5 years of age, 3.96-6.52 per 100,000 children between 5 and 10 years of age and 0.42 to 0.71 per 100,000 children between 10 and 15 years of age. Among the 824 children, 212 (25.7%) were hospitalized because of primary varicella infection. The most common complications in children were secondary bacterial infection (23%), neurological (19.1%), and respiratory (17.5%) complications. Secondary bacterial infections (p < 0.001) and neurological complications (p < 0.001) were significantly more common in previously healthy children, whereas hematological complications (p < 0.001) were more commonly observed in children with underlying conditions. The median length of the hospital stay was 6 days, and it was longer in children with underlying conditions (<0.001). The median cost of hospitalization per patient was $338 and was significantly higher in children with underlying conditions (p < 0.001). The estimated direct annual cost (not including the loss of parental work time and school absence) of varicella-related hospitalization in children under the age of 15 years in Turkey was $856,190 to $1,407,006. According to our estimates, 882 to 1,450 children are hospitalized for varicella each year, reflecting a population-wide occurrence of 466-768 varicella cases per 100,000 children. In conclusion, this study confirms that varicella-related hospitalizations are not uncommon in children, and two thirds of these children are otherwise healthy. The annual cost of hospitalization for varicella reflects only a small part of the overall cost of this disease, as only a very few cases require hospital admission. The incidence of this disease was higher in children <1 year of age, and there are no prevention strategies for these children other than population-wide vaccination. Universal vaccination is therefore the only realistic option for the prevention of severe complications and deaths. The surveillance of varicella-associated complications is essential for monitoring of the impact of varicella immunization.

Abstract
OBJECTIVE The aim of this study is to determine whether periodontal health knowledge is associated with frequency of tooth brushing and periodontal treatment need. METHODS Four hundred and two subjects participated in the study. Data on sociodemographic variables (age, gender, marital status, income, and education), general health, smoking behaviour tooth cleaning habits and knowledge on periodontal health/disease were collected with a questionnaire. Periodontal treatment need was examined using the Community Periodontal Index of Treatment Needs (CPITN). According to the CPITN scores, the treatment needs were grouped as minimum (CPITN = 0), low-level (CPITN = 1-2), or high-level (CPITN = 3-4). RESULTS Statistical differences were found between the frequency of tooth brushing and smoking status, marital status, periodontal health knowledge and periodontal treatment needs. Gender (females), place of residence (urban areas), education and periodontal health knowledge had positive relationship with tooth brushing frequency, while smoking and periodontal treatment need had negative relationship. When multivariate logistic regression analysis was applied, age, marriage and poor periodontal knowledge were associated with increased low-level periodontal treatment needs, and age, marriage and smoking were associated with increased high-level periodontal treatment need. CONCLUSION In the limits of this study, we suggest that gender, smoking habits, marital status, place of residence, education and periodontal health knowledge are determining factors related to tooth brushing frequency. Periodontal knowledge and smoking are associated with periodontal treatment needs.

Abstract
The multidrug-resistant bacterial infections cause high mortality in immunocompromised patients because of the limited antibacterial choices. Tigecycline, first member of the glycylcyclines, has in vitro activity against a wide variety of organisms, including multidrug-resistant pathogens; however, it has not yet been approved for use in children. Herein, we report a nine-year-old girl with acute myeloid leukemia who was treated successfully with tigecycline due to multidrug-resistant Escherichia coli bacteremia.

Abstract
The aim of this study was to determine the complications, financial burden and mortality caused by chickenpox using the data of Ankara, Turkey in the pre-vaccination period. The study was conducted as a retrospective sectional study. Of the 65 patients admitted to our hospital, 34 (52.3%) had been previously healthy, 10 (15.4%) had previous chronic disease and 21 (32.3%) were immunocompromised. The most common complications of chickenpox in those patient groups were skin and soft tissue infections (41.2%), hematological complications (50%) and gastrointestinal complications (38.1%), respectively. We found 10.6/100,000 and 8.7/100,000 rates of hospitalization due to chickenpox in Ankara for all children and for previously healthy children, respectively. The chickenpox-related mortality rate for the 0-17 age group was 3.03/1,000,000 in Ankara. In conclusion, we feel that a national vaccination program for chickenpox will lead to a significant decrease in the overall cost to our country.

Abstract
BACKGROUND AND OBJECTIVE Thymoquinone has a variety of pharmacologic properties, including antihistaminic, antibacterial, antihypertensive, hypoglycemic, anti-inflammatory and anti-oxidative activities. Through its anti-inflammatory and antioxidant properties, thymoquinone may play an important role in preventing periodontal diseases. The aim of this study was to evaluate the effectiveness of thymoquinone in preventing the initiation and progression of periodontitis in a rat periodontitis model. MATERIAL AND METHODS Twenty-four rats were randomly divided into three experimental groups: a nonligated (NL) treatment group (n = 8), a ligature-only (LO) treatment group (n = 8) and a ligature plus thymoquinone (10 mg/kg, daily for 11 d) (TQ) treatment group. In order to induce experimental periodontitis, a 4/0 silk suture was placed at the gingival margin of the right-mandibular first molars of the rats. Thymoquinone was administered by gastric feeding until the animals were killed on day 11. Changes in the alveolar bone levels of rats in each group were measured clinically, and tissues of rats in each group were examined histopathologically to determine inflammatory cell infiltration (ICI), osteoblast and osteoclast activities, and osteoclast morphology. RESULTS Alveolar bone loss around the mandibular molar tooth was significantly higher in the LO group compared with NL and TQ groups (p < 0.05). The ratio of the presence of ICI and osteoclast numbers was significantly higher in the LO group than in the NL and TQ groups (p < 0.05). Osteoblastic activity was significantly lower in the LO group than in the NL and TQ groups (p < 0.05). CONCLUSION The present study showed that the oral administration of thymoquinone diminishes alveolar bone resorption in a rat periodontitis model.

Abstract
The aim of this study is to document the clinical characteristics and outcomes of Acinetobacter baumannii infections in pediatric patients in a pediatric intensive care unit (PICU) in Turkey. The ages ranged from 1 month to 16 years with a mean age of 55.5 months, and the male-to-female ratio was 1:1.5. Ventilator-associated pneumonia (10 patients) was the leading diagnosis, followed by catheter-related blood stream infection (4 patients), and bacteremia and ventilator-associated pneumonia associated with meningitis (1 patient) due to A. baumannii. Mechanical ventilation (93.3%), central venous catheter (73.3%), urinary catheter (93.3%), and broad spectrum antibiotic usage (80%) were the frequently seen risk factors. Neuromuscular (40%) and malignant (26.7%) disorders were the most common underlying diseases. Nosocomial A. baumannii is commonly multidrug-resistant, prolongs the length of stay in the PICU and increases the mortality rates in pediatric critical care.
