Cardiac effects of multisystem inflammatory syndrome in children: One-year follow-up.

AIM: Cardiovascular involvement is common among children with multisystem inflammatory syndrome (MIS-C) and can cause shock and death. In this study, we evaluated the early and long-term cardiac effects of MIS-C. METHODS: In this observational cohort study, we included all children treated for MIS-C from October 2020 to November 2021 in the Department of Paediatric Infectious Disease at Cukurova University School of Medicine Hospital. The patients underwent serial echocardiographical evaluation during hospitalisation and at 1, 3, 6 and 12 months after discharge. The patients were evaluated using Holter monitorisation between 4 and 6 months and using cardiac magnetic resonance imaging at 6 months and thereafter. RESULTS: Twenty-six patients diagnosed with MIS-C and with a median age of 84 months were included. Cardiac involvement was found in 19 (73.1%) patients. At initial echocardiographic evaluation, the mean ejection fraction value of the patients was 56.7% (range: 30-75). Coronary artery dilatation was detected in two (7.7%) patients, and mitral regurgitation persisted in only one patient by month 3. Treatment was started in two (7.7%) patients due to ventricular arrhythmia. Cardiac magnetic resonance imaging was performed in 13 (50%) patients at a median of 6 months (range: 5-9). The cardiac magnetic resonance imaging findings were consistent with possible interstitial fibrosis in two (7.7%) patients. CONCLUSION: Our results showed that cardiac involvement of patients improved rapidly with treatment, as indicated by previous studies. However, during the 1-year follow-up, frequent extraventricular systole was detected in two patients, one of whom initially did not show cardiac involvement. Moreover, possible interstitial fibrosis was detected in the cardiac magnetic resonance imaging (MRI) evaluation of two patients. In particular, we believe that these findings may be useful to evaluate critically ill paediatric patients and patients with severely low EF with cardiac MRI in their follow-up.

Tuberculous meningitis during infancy: 26 cases in South Turkey among 20 years.

BACKGROUND: Due to the lack of a standard case definifion and the diffuculty in estabilishing a definitive diagnsos, TB in children needs increasing attention by physicians caring for pediatric patients. Tuberculous meningitis (TBM) is the most serious form of extrapulmonary tuberculosis that is associated with significant morbidity and mortality rate in the pediatric age group, especially in infants. This descriptive study was conducted in an University hospital, at the South of Turkey, from May 1999 to May 2019. METHODS: The hospital records of 26 TBM infant that was diagnosed at our hospital were retrospectively evaluated. The epidemiological findings (age, gender, family history of TB, tuberculin skin test results, status of BCG scaring), stage of TBM at admission and clinical, laboratory and radiological features were collected. RESULTS: Of the 26 infants, 61.5% were male and mean age of the patients was 7,65±2,6 (range, 3-12 months). The history of close contact with an infected adult was encountered in 73.1% (19 infant) of the cases. Only 69.2% of the patients (18 case) had a BCG scar. The prodromal stage (period between the onset of symptoms to hospital admission) ranged from 4 days to 180 days (39±51.3). 2 cases were defined as stage I, 10 cases as stage II and 14 cases as stage III TBM. Only two patients were initially positive for PPD test. While no neurological findings were found in 2 patients (diagnosed as stage I), neurologic findings at the time of admission included increased intracranial pressure; alteration in consciousness (92.3%), seizures (88.4%), vomiting (61.5%) cranial nerve palsy (23%), irritability 19.2%, hemiplegia 15.3% and meningeal signs (7%, only 2 patients). The presence of hepatomegaly 26.9 % and/or splenomegaly 11.5 % and/or extrapulmonary lymphadenopathy 3.8 % in nearly half of the cases suggested that totally 42,2% of cases had disseminated of tuberculosis. On admission, 46.1% of the patients were noted to have hyponatremia. Microbiologic confirmation was established in eleven (42.3%) of the 26 infant. A positive CSF culture for Mtb and/or smear for AFB and/or PCR was obtained in only 5 (19.2%) patients, whereas 3 of the cases had accompaining gastric aspirate examination positivity. Pulmonary consolidation in 14 (53.8%) patients, miliary patern in 10 (41.6%) and pulmonary hilar lymphadenopathy in only 5 (20.8%) patients. 23 (88.4 %) had hydrocephalus, 15 (57.6 %) infarction, 10 (38.4 %) basilar meningitis and 9 (34.6%) tuberculomas. Empiric anti-tuberculosis treatment was instituted in all, at a median of 3 days (range 1-15 days) following admission. 8 (30.7%) died, 3 (11.5%) recovered completely, and 15 (57.6%) recovered with sequelae. 12 case (2 died) of the infants had required ventriculoperitoneal shunting. CONCLUSION: As early diagnosis and specific treatment appears to prevent serious complications and reduce mortality, a high index of suspicion among pediatricians is especially required in an infant with an atypical picture suggestive of tuberculosis infection.

Multi-organ/disseminated echinococcosis in children: Case series and review of the literature.

AIM: Echinococcosis with multi-organ/disseminated involvement is rare in childhood. We aimed to evaluate the clinical and laboratory characteristics and prognosis in paediatric patients with echinococcosis having multiorgan/disseminated involvement. METHOD: We evaluated retrospectively children with echinococcosis with involvement of three or more organs. RESULTS: Thirteen patients were included in the study. The median age was 120 (range 71-189) months. Three (23%) were diagnosed incidentally. Abdominal pain was seen in 5 (38.4%) patients, vomiting in 4 (30.7%), headache in 3 (23%), cough in 2 (15.3%), groin pain in 1 (7.6%), 1 (7.6%) had jaundice and 1 (7.6%) had fever. The median duration of complaints was 48 (0-140) days. The most common tripartite organ was 38.4% (5/13) liver, lung and spleen. Isolated abdominal dissemination was detected in two patients. Two patients had multi-organ involvement and multiple cysts with dissemination. Cyst rupture was observed in three of the patients; recurrent urinary tract infection, hydroureteronephrosis, secondary peritonitis with intra-abdominal abscess, and biliary tract fistula were each observed in one patient. Relapse developed in 3 (23%) patients. CONCLUSION: Echinococcosis is a very slow growing and complex parasitic disease that affects many organs and tissues. In our study, eosinophilia, recurrence, and complications were seen at a higher rate in paediatric patients with multiorgan involvement, who required repetitive surgeries and long-term medical treatment. However, there are scanty data on risk factors, optimum treatment and prognosis.

Treatment of Candida urinary tract infections with micafungin in children.

BACKGROUND: Candida urinary tract infections (UTIs) are common nosocomial infections among critically ill patients hospitalized in pediatric intensive care Units (PICU). We aimed to report outcomes of critically ill pediatric patients who received micafungin for hospital acquired Candida UTIs. We analyzed treatment success rates and success rates among different Candida species. METHODS: This retrospective cohort study included patients who received micafungin for Candida UTI as first choice in our PICU between January 2017 and July 2018. Data, including demographic and clinical features, were retrospectively collected from medical files of the patients. Treatment efficacy was defined as resolution of clinical symptoms and a negative culture for Candida at day 14 after initiation of micafungin treatment. RESULTS: Twenty-four pediatric patients (median age 5.72 years, range, 2 months-16 years) were included in the present study. Fourteen (58.3%) patients had urinary catheters at the time of Candida isolation. Resolution of symptoms and a negative culture at day 3 of micafungin treatment were achieved in 17 (70.8%) and 14 (58.3%) patients, respectively. Moreover, 19 (79.2%) patients had a normal urine analysis and negative culture 14 days after initiation of micafungin treatment. Treatment responses did not statistically differ between Candida species. CONCLUSIONS: Micafungin is safe and efficacious in critically ill pediatric patients with Candida UTIs. Its efficacy in our pediatric population was as comparable to that observed in adult studies, therefore, it should be considered as an effective therapeutic option in Candida UTIs of critically ill pediatric patients.

Experience with enterococcal meningitis/ventriculitis in children.

BACKGROUND: Enterococcal infections are increasingly common in hospitalized patients. Enterococcal meningitis/ventriculitis (EMV) is an extremely rare condition of enterococcal infections, occurring particularly in children. This study investigated the clinical and microbiological characteristics, predisposing factors, and prognosis in pediatric patients with EMV. METHODS: Pediatric patients (<18 years) diagnosed with EMV were retrospectively evaluated over 10 years. RESULTS: The study included a total of 25 isolates from 24 patients, median age 23 months (range: 1-136 months). The most common symptoms included vomiting, fever, and headache, with hydrocephalus shunt and preterm birth being the two most common conditions. Commonly associated infections, with central nervous system (CNS) devices as a predisposing factor, were due to external ventricular drainage and ventriculoperitoneal shunts. Two patients with spontaneous meningitis were preterm infant. Of the isolates, 44% were Enterococcus faecalis, 44% E. faecium, and 12% E. gallinarum. Five (20%) isolates were vancomycin resistant. Twelve patients were resistant to anti-enterococcal antibiotics, including ampicillin, ciprofloxacin, imipenem, teicoplanin, gentamicin, and linezolid (40%, 20%, 8%, 8%, 4%, and 4%, respectively). Enterococcus faecium was more resistant to ampicillin, ciprofloxacin, teicoplanin, and vancomycin than E. faecalis. The median treatment duration was 17 days (interquartile range: 14-26 days).The mortality rate was 8.3% (2/24; both associated with vancomycin resistance). CONCLUSIONS: Neurosurgical conditions are the most common predisposing factors for EMV. Preterm birth is an important predisposing factor in children. Because EMV is nonspecific in clinical findings, it should be considered when there is an underlying CNS disorder and empirical treatment should begin in this direction.

Tumor necrosis factor alpha and interleukin-1 beta levels in cerebrospinal fluid examination for the diagnosis of ventriculoperitoneal shunt-related ventriculitis.

PURPOSE: Ventriculitis is known to develop after chronic inflammation and bacterial invasion of the ventricular surface with a recurrence of shunt infections. The aim of this study is to evaluate the diagnostic value of elevation in cerebrospinal fluid (CSF) interleukin-1 beta (IL-1ß) and tumor necrosis factor alpha (TNF-α) together with CSF culture and laboratory test results in the diagnosis of ventriculoperitoneal (VP) shunt-related ventriculitis, which is known to be more problematic than conventional shunt infection. METHODS: The study included a total of 34 patients with a VP shunt due to hydrocephalus, who presented with a headache, fever, and shunt infection at the Emergency Department and had a pre-diagnosis of ventriculitis. Nineteen patients were diagnosed with shunt-related infection or ventriculitis using the CSF obtained from the shunt pump. The IL-1ß and TNF-α levels from the CSF samples of all patients were measured using the Micro ELISA immunoassay method. RESULTS: CSF direct microscopic observation revealed that the mean cell count, IL-1ß level, CRP level, and blood leukocyte level were higher in patients with ventriculitis compared to those diagnosed with shunt infection (p = 0.02, p = 0.009, p = 0.004, and p = 0.009, respectively). The probability of predicting positive culture outcome was 92.7% with 90.9% sensitivity and 82.6% specificity when IL-1ß values exceeded 4.0 pg/ml. TNF-α values did not show a significant, reliable pattern compared to IL-1ß. CONCLUSIONS: IL-1ß is a reliable parameter which shall be used in the diagnosis of ventriculitis by predicting positive culture outcome with high sensitivity and specificity.

A comparative analysis of different molecular targets using PCR for diagnosis of old world leishmaniasis.

The different sensitivity values were obtained in each study conducted for the diagnosis of leishmaniasis with the polymerase chain reaction (PCR). However, a standardized PCR target for the diagnosis of leishmaniasis does not exist. The aim of the current study, the most ideal PCR target was determined for diagnosis of leishmaniasis. A total of 72 smear and 48 bone marrow samples were analyzed with six different molecular targets to determine their potential as a tool for the specific molecular diagnosis of leishmaniasis using PCR. The positivity-negativity value and the sensitivity-specificity of each PCR targets were calculated. The positivity value of PCR targets were sequenced in different levels in the diagnosis of leishmaniasis from highest to lowest in the order of kDNA-PCR > SSU rRNA-PCR > ITS2-PCR > ITS1-PCR > ME-PCR > HSP70-PCR. The sensitivities of PCR targets except ITS1-PCR, ME-PCR and HSP70-PCR were found to be 100% in cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) cases as compared to microscopic examination accepted as a gold standard. The sensitivities of ITS1-PCR, ME-PCR and HSP70-PCR were found 96.6%, 90.0% and 86.6%, respectively, in CL-cases. In addition, the sensitivities of ITS1-PCR, ME-PCR and HSP70-PCR were found 90.0%, 70.0% and 60.0%, respectively, in VL-cases. The kDNA genomic region was the most sensitive for routine diagnosis of leishmaniasis. ITS1-PCR restriction fragment length polymorphism, the alternative method for the identification of Old World Leishmania species, did not require culturing of the parasites.

Clinical manifestations and genetic variation of Leishmania infantum and Leishmania tropica in Southern Turkey.

L. infantum was isolated from cutaneous leishmaniasis (CL) skin lesions in patients having no signs and symptoms of visceral leishmaniasis (VL). Similarly, L. tropica had previously been isolated from patients with VL in the absence of cutaneous lesions. It was not certain how visceralization occurred. Smears (207) and bone marrow samples (135) were taken from CL and VL-suspected patients, respectively. Microscopic examination, ITS1-PCR, RFLP and DNA sequencing for all samples were analyzed. The microscopic examination of smears was found to be 61.3% (127/207) in CL-suspected cases and bone marrow samples were found to be positive 8.8% (12/135) in VL-suspected cases. L. tropica 48.6% (72/148), L. infantum 35.8% (53/148), L. major 15.6% (23/148) in CL, and L. infantum 56.3% (18/32), L. donovani 31.2% (10/32), L. tropica 12.5% (4/32) in VL were found with PCR-RFLP. In addition, the DNA sequencing revealed a genetic variation in L. infantum (variants 1-3) and L. tropica (variants 1-5). We assume that the increased disease occurrence may have resulted from geographical expansion of disease, changing patterns of international travel, population migrations, non-immune people into endemic regions of infected people into non-endemic regions. In this study, L. infantum (variant 3) only in CL-patients and L. tropica (variant 2) only in VL-patients were identified. We hypothesize that genetic variation might play a role in the causation of CL and VL in southern Turkey and the genetic variants may differ according to the geographical location among Leishmania strains.

Congenital Toxoplasmosis and Long-term Outcomes

Objective: Congenital toxoplasmosis (CT) can have severe early and late sequelae in children. In this study, we aimed to evaluate the demographic, clinical, treatment characteristics of patients diagnosed with congenital Toxoplasma infection and to highlight the long-term complications of the patients. Methods: Patients with CT were included in this study who were followed between 2010 and 2022 in Cukurova University Medical Faculty Hospital. Demographic, clinical and treatment characteristics were searched retrospectively. In the diagnosis of maternal and CT, Toxoplasma IgM, IgG, IgG avidity, T. gondii polymerase chain reaction tests were used along with clinical and symptoms. Results: Eighteen children (two twins) with CT and their mothers (n=16) were included in the study. Median age was 1 month. Ten (55.5%) of the children were male. CT diagnosis was made during pregnancy in 7 mothers (resulting in 8 babies) and postnatally in 9 mothers (resulting in 10 babies). The mothers of 5 (31.1%) babies with CT received spiramycin treatment during pregnancy. Three (60%) of 5 pregnant women who received spiramycin were diagnosed in the first trimester, 4 (80%) of the babies did not have any sequale and only 1 (20%) had microphthalmia. Ocular involvement was the most common presentation of the disease occured in 10 patients (55.5%), hydrocephalus and intracranial calcification developed in five patients (27.7%). Hearing loss developed in 2 (11.1%) patients. During the follow-up period, seizures developed in 3 patients (16.6%), microcephaly in 2 patients (11.1%), and neurodevolopmental retardation in 7 patients (38.8%), two of the patients had severe mental retardation. One (5.5%) patient with hydrocephalus died at 36 months of age due to complications after ventriculoperitoneal shunt application. Conclusion: In our study, we observed severe sequelae in vision, hearing, and neurodevelopmental aspects in children diagnosed with CT at birth and during follow-ups. Early diagnosis and treatment of infants, along with the detection of Toxoplasma infection during pregnancy, are essential in preventing severe sequelae that may arise due to CT.

Candida parapsilosis candidemia in children admitted to a tertiary hospital in Turkey: clinical features and antifungal susceptibility.

In recent years, the incidence and drug resistance of Candida parapsilosis have increased. Our study aimed to determine the antifungal sensitivity of C. parapsilosis and the clinical and demographic characteristics of children with candidemia. Two hundred pediatric patients with C. parapsilosis candidemia were included in the study between 1 January 2010 and 1 August 2023. Clinical samples were evaluated on a BACTEC-FX-40 automatic blood culture device (Becton Dickinson, USA). Yeast isolates were identified to the species level via identification cards (YST) using the VITEK 2 Compact (bioMeriéux, France) system. Antifungal susceptibility was performed using antifungal cell cards (AST-YST01). Approval for the study was received from the "University Faculty of Medicine" Hospital Clinical Research Ethics Committee. Non-catheter candidemia was detected in 127 (63.5%) patients, and catheter-related candidemia was detected in 73 (36.5%) patients. It was observed that the patients' history of malignancy, mechanical ventilation, urinary catheter, nasogastric tube, and intensive care unit stay was associated with C. parapsilosis mortality. The mortality rate from candidemia was 9.5%. The most frequently preferred antifungal agents were amphotericin B and fluconazole. The fluconazole drug resistance rate was found to be 6%, and the amphotericin B drug resistance rate was 4%. Because C. parapsilosis candidemia mortality rates can be high depending on risk factors and clinical characteristics, it is important to initiate appropriate and timely antifungal therapy. We think that our study can provide important information about the clinical profiles, distributions, susceptibility profiles, and control of antifungal resistance of C. parapsilosis isolates. IMPORTANCE: It has been observed that the frequency and antifungal resistance of Candida parapsilosis have increased recently. In our study, we aimed to determine the antifungal sensitivity of C. parapsilosis and the clinical and demographic characteristics of children with candidemia. It was observed that the patients' history of malignancy, mechanical ventilation, urinary catheter, nasogastric tube, and intensive care stay was associated with C. parapsilosis mortality. The mortality rate from candidemia was 9.5%. The most frequently preferred antifungal agents were amphotericin B and fluconazole. The fluconazole drug resistance rate was found to be 6%, and the amphotericin B drug resistance rate was 4%. Because C. parapsilosis candidemia mortality rates can be high depending on risk factors and clinical characteristics, it is important to initiate appropriate and timely antifungal therapy.

Pathogens in Pediatric Septic Arthritis: A Multi-Center Study in Turkiye (PEDSART Study).

OBJECTIVES: Septic arthritis (SA) is a serious bacterial infection that must be treated efficiently and timely. The large number of culture-negative cases makes local epidemiological data important. Accordingly, this study aimed to evaluate the etiology, clinical characteristics, and therapeutic approach of SA in children in Turkiye, emphasizing the role of real-time polymerase chain reaction (PCR) techniques in the diagnosis. METHODS: In this multi-center, prospective study, children hospitalized due to SA between February 2018 and July 2020 in 23 hospitals in 14 cities in Turkiye were included. Clinical, demographic, laboratory, and radiological findings were assessed, and real-time PCR was performed using synovial fluid samples. RESULTS: Seventy-five children aged between 3 and 204 months diagnosed with acute SA were enrolled. Joint pain was the main complaint at admission, and the most commonly involved joints were the knees in 58 patients (77.4%). The combination of synovial fluid culture and real-time PCR detected causative bacteria in 33 patients (44%). In 14 (18.7%) patients, the etiological agent was demonstrated using only PCR. The most commonly isolated etiologic agent was Staphylococcus aureus, which was detected in 22 (29.3%) patients, while Streptococcus pyogenes was found in 4 (5.3%) patients and Kingella kingae in 3 (4%) patients. Streptococcus pyogenes and Kingella kingae were detected using only PCR. Most patients (81.3%) received combination therapy with multiple agents, and the most commonly used combination was glycopeptides plus third-generation cephalosporin. CONCLUSIONS: Staphylococcus aureus is the main pathogen in pediatric SA, and with the use of advanced diagnostic approaches, such as real-time PCR, the chance of diagnosis increases, especially in cases due to Kingella kingae and Streptococcus pyogenes.

Safety and efficacy of AK0529 in respiratory syncytial virus-infected infant patients: A phase 2 proof-of-concept trial.

Background: Respiratory syncytial virus (RSV) infection is a cause of substantial morbidity and mortality in young children. There is currently no effective therapy available. Methods: This was a Phase 2 study of the oral RSV fusion protein inhibitor AK0529 in infants aged 1-24 months, hospitalized with RSV infection. In Part 1, patients (n = 24) were randomized 2:1 to receive a single dose of AK0529 up to 4 mg/kg or placebo. In Part 2, patients (n = 48) were randomized 2:1 to receive AK0529 at 0.5, 1, or 2 mg/kg bid or placebo for 5 days. Sparse pharmacokinetic samples were assessed using population pharmacokinetics modelling. Safety, tolerability, viral load, and respiratory signs and symptoms were assessed daily during treatment. Results: No safety or tolerability signals were detected for AK0529: grade ≥3 treatment-emergent adverse events occurring in 4.1% of patients in AK0529 and 4.2% in placebo groups, respectively, and none led to death or withdrawal from the study. In Part 2, targeted drug exposure was reached with 2 mg/kg bid. A numerically greater reduction in median viral load with 2 mg/kg bid AK0529 than with placebo at 96 h was observed. A -4.0 (95% CI: -4.51, -2.03) median reduction in Wang Respiratory Score from baseline to 96 h was observed in the 2 mg/kg group compared with -2.0 (95% CI: -3.42, -1.82) in the placebo group. Conclusions: AK0529 was well tolerated in hospitalized RSV-infected infant patients. Treatment with AK0529 2 mg/kg bid was observed to reduce viral load and Wang Respiratory Score. Clinical Trials Registration: NCT02654171.

Identification of Leishmania tropica from Pediatric Visceral Leishmaniasis in Southern Mediterranean Region of Turkey.

Background and Objective: Protozoa of the genus Leishmania are obligate intracellular parasites, and Leishmania species cause a spectrum of species-specific clinical symptoms known as cutaneous, mucocutaneous, and visceral leishmaniasis. For example, Leishmania major and Leishmania tropica cause cutaneous leishmaniasis, while Leishmania infantum and Leishmania donovani cause visceral leishmaniasis (VL). However, molecular studies in recent years have shown that Leishmania species cause different clinical symptoms. Objectives: Our aim was to evaluate the relationship between the clinical and molecular characterization of leishmania isolates in children with VL defined in Turkey, an intercontinental transitional region. Methods: The clinical diagnosis of VL was confirmed by detecting amastigotes in the bone marrow aspirate and/or the rK39 test and/or molecular methods (genus-specific PCR, Real-Time PCR, ITS1 PCR-RFLP, DNA sequencing). Results: Most of the VL patients were referred from the districts of Adana (53.3%) and others from neighboring provinces; Hatay (16.6%), Osmaniye (3%), Gaziantep (3%), Adiyaman (3%), and 20% case were Syrian immigrants A clinical diagnosis of VL was confirmed in 30 patients with different diagnostic methods. 93% was found positive with microscopic examination, 79.1% with rK39 dipstick test, and 60% with genus-specific PCR assay in clinical samples. The Leishmania isolates were identified as L. infantum (40%), L. donovani (26.7%), and L. tropica (23.3%) using Real-Time PCR, ITS1 PCR-RFLP, and DNA sequencing. There was no cutaneous finding in any case in clinical examination.The most common clinical findings were fever (93.3%) and splenomegaly (90%), followed by hepatomegaly (76.6%). The most common laboratory finding was thrombocytopenia (86.6%), followed by anemia (70%). In addition, hemophagocytic lymphohistiocytosis was detected in bone marrow aspiration in two of our patients. Since pentavalent antimony salts treatment initially failed in four patients, it was necessary to switch to Liposomal-Amphotericin B with treatment success. Conclusions: The presence of L. tropica in VL patients, despite the absence of cutaneous findings in any of the cases, shows that this strain can cause VL, contrary to conventional knowledge. In the Adana province, where this study was carried out, L. infantum from CL cases in previous studies should be taken into account, and visceral spread in CL cases and accompanying cutaneous lesions in VL cases should be investigated in detail.

Recurrence from the Spinal Region of the Patient Whose Treatment Was Completed with Liver and Lung Cystic Echinococcosis: A Rare Pediatric Case of Spinal Cystic Echinococcosis

Cystic echinococcosis is a parasitic disease caused by the Echinococcus tapeworm. The disease can often affect organs such as the liver and lungs, muscles, bones, kidneys, brain, and spleen. Spinal cystic echinococcosis has been reported very rarely in the literature. In this report; we present a pediatric case with spinal cystic echinococcosis, who was diagnosed with multiple cystic echinococcosis in the liver and lungs and was admitted with complaints of difficulty in walking and leg pain 1 year after the albendazole treatment, which he had been taking for 3.5 years. If a diagnosis of cystic echinococcosis was made in any organ, recurrences may occur in another organ at some time, even if the treatment is completed.

The effectiveness of topical 1% lidocaine with systemic oral analgesics for ear pain with acute otitis media.

BACKGROUND: Acute otitis media (AOM) is one of the most common childhood infections. Ear pain, the main symptom of AOM, results in parents frequently seeking medical assistance for their children. The aim of this study was to compare the effectiveness of topical 1% lidocaine ear drops administered with oral analgesics with that of oral analgesics alone. METHODS: This multicenter randomized, open-labeled study was conducted at 15 centers with 184 pediatric AOM patients with bilateral ear pain (aged 1-5 years) between May 1, 2016, and June 31, 2018. All patients received oral paracetamol or ibuprofen and topical 1% lidocaine, which was administered to each ear according to the randomization list. The ear pain score was evaluated within 48 h using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale, and the patients were followed up for 10 days. RESULTS: The median age was 31.8 months (min-max, 12-84.2 months). Of those patients enrolled, 22.3% received paracetamol, and 24.5% received paracetamol with lidocaine ear drops; 23.4% received ibuprofen, and 29.9% received ibuprofen with lidocaine ear drops. Lower pain scores were significantly measured at baseline and 10th minutes by a reduction 25% (RR 13.64, 95% CI 4.47-41.63, p = 0.001, RR 0.14, 95% CI 0.06-0.35, p = 0.001) and 50% (RR 4.76, 95% CI 1.63-13.87, p = 0.004, RR 0.14, 95% CI 0.05-0.4, p = 0.001) in the paracetamol and lidocaine versus paracetamol groups and the ibuprofen and lidocaine versus ibuprofen groups, respectively. No serious side effects were evident during follow-up. CONCLUSION: This randomized study suggests that topical 1% lidocaine ear drops with paracetamol or ibuprofen seems to provide effective and rapid relief for children presenting with ear pain attributed to AOM.

Bloodstream infections due to Trichosporon species in paediatric patients: Results from the first national study from Turkey.

BACKGROUND: Invasive Trichosporon infections are rarely seen opportunistic fungal infections in children and mainly affect immunocompromised patients. This multicenter retrospective study has rewieved the characteristics, risk factors, treatment modalities and outcomes of bloodstream infections caused by Trichosporon species in children diagnosed over the past ten years in Turkey. METHODS: The study was performed with the participation of 12 of 55 hospitals invited from Turkey. In each center, the patients with bloodstream infections caused by Trichosporon spp. between January 2010 and December 2020 were retrospectively ascertained and the results were reported to the study coordinator by means of a simple case report. Data were collected on patient demographics, underlying condition(s), treatment of.infections caused by Trichosporon spp, and 7 and 30- day mortality rates. RESULTS: A total of 28 cases with fungemia caused by Trichosporon spp. were included in the study. The most common underlying disease was paediatric cancers (39.3%). T. asahii infections were detected in 78.5 % (n=22) of patients. A various spectrum of antifungal treatment regimens were used including intravenous amphotericin B monotherapy in 35.7%, intravenous amphotericin B and voriconazole combination in 32.1% and intravenous voriconazole monotherapy in 28.6% of the patients. The overall mortality rate was 28.5 %. The mortality rates were 12.5% in the voricanozole, 30% in the amphotericin B and 33.3% in combined voriconazole -amphotericin B arms CONCLUSIONS: Invasive Trichosporon infections with an important impact of patients quality of life are almost related to underlying diseases with an overall mortality rate of 28.5%. Voriconazole was found to be associated with lower mortality rates when compared with other treatment regimens.

Mucormycosis in a pediatric population: a review of 20 cases from southern Turkey.

BACKGROUND: Mucormycosis is a fatal invasive fungal infection seen most often in patients with compromised defense mechanisms. The aim of this article was to review the data of pediatric mucor in the South of Turkey. METHODS: Twenty pediatric cases with biopsy proven mucormycosis were reported, between January 2007 through January 2017. Data were extracted from the medical charts of patients retrospectively. RESULTS: Underlying conditions were hematological malignancy (75%), in whom 93% had acute leukemia, aplastic anemia (15%), diabetes mellitus (5%) and other malignancies (5%). The main sites of infection were sinus (85%); alone (29.4%) or with cerebral (17.6%), and orbital involvement (17.6%). Pulmonary involvement was reported in 11 patients (55%), two of them had the alone form and nine cases were associated with nasal sinus involvement. Disseminated mucormycosis was documented in 45%. Fever and pain/swelling of organs were the most commonly encountered signs and symptoms. Treatment compromised of am-photericin B monotherapy in five patients. All patients except one received liposomal formu-lations (LAmB). A combination of surgery and antifungal therapy was performed in 75%. Crude survival was 55%; among 15 cases treated with a combination of surgery and antifun-gal therapy, survival rate was 8/15 (53%). The overall mortality rate was high in patients diagnosed with disseminated infection (100%). CONCLUSIONS: Mucormycosis in pediatric cases requires a high index of suspicion and urgent evaluation of clinical samples. Surgical debridement should be considered when feasible. Initial medical therapy should include an amphotericin preparation with or step-down to posaconazole.

Carbapenem and colistin resistance in children with Enterobacteriaceae infections.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) are an emerging global public health threat. As a reserve agent, colistin has been the drug of choice for the treatment of infections caused by CRE. The aim of this study was to determine the risk factors of carbapenem and colistin-resistant Enterobacteriaceae infections and to investigate the outcomes. METHODS: We conducted a retrospective study in a single university hospital between the years 2013 and 2017 including 150 patients with Enterobacteriaceae infections. RESULTS: Of 150 Enterobacteriaceae infections, 62 (41%) were carbapenem and 23 (15%) were colistin-resistant. Colistin resistance rates among Enterobacteriaceae species increased from 4% in 2014 to 25% in 2017. The inhospital mortality of the patients with colistin-resistant and with carbapenem-resistant infections were 39% (9/23) and 45% (28/62), respectively. Prior exposure to polyantibiotic therapy for Gram negative bacteria was found as a predictor of CRE (OR = 6.4; 95% CI 3.07-13.6; p = 0.001) infections. The median length of hospital stay prior to positive culture (OR = 1.02; 95%CI, 1.0-1.04; p = 0.003) and history of surgery during the admission (OR = 2.46; 95% CI 1.2-5.1; p = 0.005) were found as the predictors of CRE infections. Underlying necrotizing enterocolitis and/or short-bowel syndrome (OR=6.38; 95%CI 1.16-35; p = 0.033) and mechanical ventilation prior to index culture were found as predictors of colistin resistance (OR = 9.4; 95% CI 2-40.4; p = 0.004). CONCLUSIONS: Recognizing the risk factors of carbapenem and colistin resistant Enterobacteriaceae infections is essential in order to conserve carbapenem and colistin since there are no new antibiotics to treat multidrugresistant Enterobacteriaceae infections.
