Sphingomonas paucimobilis is an aerobic, non-fermentative, opportunistic Gram-negative bacillus found in water systems. This study was conducted to analyze concurrent S. paucimobilis bacteremia cases ...and treatment outcomes, potential outbreak sources, and antimicrobial resistance profiles. This ambidirectional cohort study was conducted in a 30-bed pediatric hematology-oncology hospital. The patients’ ages ranged from 1 to 17 years, with a median age of 5 years. Environmental sampling was applied to investigate the outbreak source. Bacterial identification and antimicrobial susceptibility tests of the isolated bacteria were performed using the disk diffusion method and Vitek®2 automated system. S. paucimobilis was detected in 181 blood culture samples from 51 patients over 2 years and was isolated from hot tap water. Acute lymphoblastic leukemia (ALL) was diagnosed for 66% of patients, and two of our patients with ALL died due to S. paucimobilis sepsis. S. paucimobilis isolates are susceptible to carbapenems and quinolones. Surveillance and epidemic control should be performed for hospital-acquired infectious agents such as S. paucimobilis. In additon, water distribution systems should be checked for colonizing agents at regular intervals.
The aim of this study was to examine the intima-media thickness (IMT) of carotid arteries and endothelial function parameters such as plasma asymmetric dimethylarginine (ADMA) and homocysteine levels ...in hypercholesterolemic children and to investigate the relations of these parameters with hypercholesterolemia. Fifty-seven hypercholesterolemic and 37 healthy children were included in the study. Hypercholesterolemia was defined as 155 mg/dl and above for low-density lipoprotein (LDL)-cholesterol. Plasma concentrations of ADMA and homocysteine were measured and the measurement of carotid IMT was determined. Both carotid IMT and plasma ADMA levels were significantly higher in hypercholesterolemic children than healthy children (p<0.01). No significant difference was determined in homocysteine concentration between hypercholesterolemic children and the control group (p>0.05). No significant correlation was observed between lipid profiles and the levels of ADMA and homocysteine. However, a significant positive correlation was found between carotid IMT and total and LDL-cholesterol levels and between the levels of ADMA and LDL-cholesterol. In conclusion, the progressive increase in ADMA levels and carotid IMT and the positive relationship between carotid IMT and serum cholesterol levels support that plasma ADMA levels and carotid IMT can be indicators of early atherosclerosis in hypercholesterolemic children.
Tularemia is a zoonotic disease caused by Francisella tularensis. The clinical forms mostly depend on the port of entry into humans. Ingestion typically results in the oropharyngeal form and is ...associated with symptoms such as fever, pharyngitis, cervical lymphadenitis, and suppuration. In this report, we describe a child treated for Hodgkin's disease presenting six years later with a left cervical lymphadenopathy mimicking a relapse.
Bloom syndrome (BS) is a rare autosomal recessive inherited disorder. Patients with BS have photosensitivity, telangiectatic facial erythema, and stunted growth. They usually have mild microcephaly, ...and distinctive facial features such as a narrow, slender face, micrognathism, and a prominent nose. Kostmann disease (KD) is a subgroup of severe congenital neutropenias. The diagnosis of severe congenital neutropenia is based on clinical symptoms, bone marrow findings, and genetic mutation. Here, we report a female patient with a triangular face, nasal prominence, and protruding ears presenting with recurrent infections and severe neutropenia. Molecular genetic testing revealed a compound heterozygous variant in the HCLS-1-associated protein X-1 gene (c.130_131insA) p.(trp44*), c.430 dup(p.Val144fs) and a new homozygous variant in Bloom Syndrome RecQ like helicase gene c.2074+2T>C p.(?). She was diagnosed with both BS and KD. To the best of our knowledge, this is the first case of coexisting BS and KD in a patient ever reported.
Cancer was a common noncommunicable disease in Syria before the present conflict and is now a major disease burden among 3.6 million Syrian refugees in Turkey. Data to inform health care practice are ...needed.
To explore sociodemographic characteristics, clinical characteristics, and treatment outcomes of Syrian patients with cancer residing in the southern border provinces of Turkey hosting more than 50% of refugees.
This was a retrospective hospital-based cross-sectional study. The study sample consisted of all adult and children Syrian refugees diagnosed and/or treated for cancer between January 1, 2011, and December 31, 2020, in hematology-oncology departments of 8 university hospitals in the Southern province of Turkey. Data were analyzed from May 1, 2022, to September 30, 2022.
Demographic characteristics (date of birth, sex, and residence), date of first cancer-related symptom, date and place of diagnosis, disease status at first presentation, treatment modalities, date and status at last hospital visit, and date of death. The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision and International Classification of Childhood Cancers, Third Edition, were used for the classification of cancer. The Surveillance, Epidemiology, and End Results system was applied for staging. The diagnostic interval was defined as the number of days from first symptoms until the diagnosis. Treatment abandonment was documented if the patient did not attend the clinic within 4 weeks of a prescribed appointment throughout the treatment.
A total of 1114 Syrian adult and 421 Syrian children with cancer were included. The median age at diagnosis was 48.2 (IQR, 34.2-59.4) years for adults and 5.7 (IQR, 3.1-10.7) years for children. The median diagnostic interval was 66 (IQR, 26.5-114.3) days for adults and 28 (IQR, 14.0-69.0) days for children. Breast cancer (154 13.8%), leukemia and multiple myeloma (147 13.2%), and lymphoma (141 12.7%) were common among adults, and leukemias (180 42.8%), lymphomas (66 15.7%), and central nervous system neoplasms (40 9.5%) were common among children. The median follow-up time was 37.5 (IQR, 32.6-42.3) months for adults and 25.4 (IQR, 20.9-29.9) months for children. The 5-year survival rate was 17.5% in adults and 29.7% in children.
Despite universal health coverage and investment in the health care system, low survival rates were reported in this study for both adults and children with cancer. These findings suggest that cancer care in refugees requires novel planning within national cancer control programs with global cooperation.
The aim of this study was to evaluate the relationship between cerebrospinal fluid (CSF) osteopontin (OPN) levels and central nervous system (CNS) involvement in children with a diagnosis of acute ...leukemia. The study sample consisted of 62 patients who had been diagnosed with acute leukemia. The control group consisted of 16 patients that had presented and had no malignant disease, CNS infection or chronic disease. CSF OPN levels were studied with enzyme-linked immunosorbent assay (ELISA) method. The mean CSF OPN level was 32.76±49.22 ng/ml in the patients at the time of diagnosis and 14.93±6.84 ng/ml in the control group (p>0.05). The mean CSF OPN level was 27.68±32.73 ng/ml at the time of diagnosis in the group without CNS involvement and 53.48±89.21 ng/ml in the group with CNS involvement (p>0.05). However, the CSF OPN level at the time of CNS relapse in patients who developed CNS involvement during follow-up (127.4±52 ng/ml) was significantly higher than in the group without CNS involvement at diagnosis and follow-up (mean CSF OPN level: 27.68±32.73 ng/ml) (p<0.001). The analysis of CSF OPN levels at the time of diagnosis-before relapse and at the periods of relapse and remission in patients who had CNS involvement at diagnosis and/or follow-up revealed statistically significant differences between the time points (p<0.001). High CSF OPN levels in childhood acute leukemia patients may be used as evidence for CNS involvement, and any increases found in CSF OPN levels may be a preliminary predictor for CNS involvement.
Objective: Childhood adrenocortical tumors (ACTs) are rare neoplasms, about which etiopathogenesis and disease management are not yet clearly understood. We aimed to review the management of ACTs in ...our single medical center. Methods: We retrospectively reviewed findings in seven children, who were 15 years old or younger, and were diagnosed with ACTs in our institution over the past 10 years. Information recorded for each patient included age, sex, presenting symptoms, hormonal status, pathological findings, stage of disease, treatment and outcome. Results: Four girls and three boys were treated for ACTs. Five had adrenocortical carcinoma (ACC) and two had adrenocortical adenoma (ACA).
All patients underwent laparotomy and complete excision. Two of ACCs had a stage I disease, one had a stage III, and the latter two ACCs had a stage IV disease. ACAs were treated successfully by total excision without any concomitant therapy. Adjuvant chemotherapy and mitotane were commenced postoperati
İncesoy-Özdemir S, Ertem U, Şahin G, Bozkurt C, Yüksek N, Ören AC, Balkaya E, Alkan A. Clinical and epidemiological characteristics of children with germ cell tumors: A single center experience in a ...developing country. Turk J Pediatr 2017; 59: 410-417. Germ cell tumor (GCT) is a rare malignancy accounting for 2-3% of all pediatric tumors. The overall survival rate of children and adolescents with GCT is more than 80% after adopting combined therapy. The aim of this study is to review clinical presentation, management, and outcome in a single-center series with extracranial GCT. Clinical characteristics, pathologic presentations, and survival outcomes of 101 children with GCT, treated at our hospital from 1988 to 2011, were analyzed. Sixty-two of patients were female and 39 of them were male. Fifty-eight (57%) patients had gonadal tumor (24 testicular, 34 ovarian), 43 (43%) extragonadal. Histologically, teratomas were found most frequently (26 mature, 10 immature), followed by yolk sac tumors (n: 33), mixed malignant tumors (n: 13), embryonal carcinoma (n: 10), disgerminoma (n: 8) and seminoma (n: 1). Twenty-six patients were diagnosed as mature teratoma and we excluded them in the evaluation of staging and survival. Five-year overall and relaps-free survival were 80.3% (mean follow-up time: 215.8 months) and 73.4% (mean follow-up time: 176.2 months), respectively. Five-year survival rates were 93.2% and 90.2% in malign GCTs diagnosed after 1999.
Background
In patients with acute lymphoblastic leukemia (ALL), the risk of thromboembolism increases due to hemostatic changes secondary to the primary disease and due to treatment‐related factors. ...In this multicenter study, we aimed to research the frequency of central nervous system (CNS) thrombosis occurring during treatment, hereditary and acquired risk factors, clinical and laboratory features of patients with thrombosis, treatment approaches, and thrombosis‐related mortality and morbidity rates in pediatric ALL patients.
Procedure
Pediatric patients who developed CNS thrombosis during ALL treatment from 2010 to 2021 were analyzed retrospectively in 25 different Pediatric Hematology Oncology centers in Türkiye. The demographic characteristics of the patients, symptoms associated with thrombosis, the stage of the leukemia treatment during thrombosis, the anticoagulant therapy applied for thrombosis, and the final status of the patients recorded through electronic medical records were determined.
Results
Data from 70 patients with CNS thrombosis during treatment, out of 3968 pediatric patients with ALL, were reviewed. The incidence of CNS thrombosis was 1.8% (venous: 1.5 %; arterial: 0.03%). Among patients with CNS thrombosis, 47 had the event in the first 2 months. Low molecular weight heparin (LMWH) was the most commonly used treatment with a median of 6 months (min–max: 3–28 months). No treatment‐related complications occurred. Chronic thrombosis findings occurred in four patients (6%). In five (7%) patients who developed cerebral vein thrombosis, neurological sequelae (epilepsy and neurological deficit) remained. One patient died related to thrombosis, and the mortality rate was 1.4%.
Conclusion
Cerebral venous thrombosis and, less frequently, cerebral arterial thrombosis may develop in patients with ALL. The incidence of CNS thrombosis is higher during induction therapy than during other courses of treatment. Therefore, patients receiving induction therapy should be monitored carefully for clinical findings suggestive of CNS thrombosis.
