Difficulties in the management of an Askin tumor in a pediatric patient with cystic fibrosis: case report and literature review.

Treating Ewing's Sarcoma of the thorax (Askin's tumor) with antineoplastic therapy in a malnourished cystic fibrosis patient colonized with Pseudomonas aeruginosa and Staphylococcus aureus may carry a significant potential for complications. We present the case of a known cystic fibrosis patient, diagnosed with Askin's tumor 5 years ago. Despite facing severe neutropenia, exacerbations of cystic fibrosis with Pseudomonas aeruginosa infections, and challenges in maintaining adequate caloric intake during the oncological treatment, the patient's outcome has been favorable. Chemotherapy doses had to be adjusted, and continuous antibiotic treatment was introduced throughout the course of therapy to reduce the frequency and intensity of exacerbations. Approximately 5 years after the cancer diagnosis, with no signs of relapse, the patient was started on CFTR (Cystic fibrosis transmembrane conductance regulator) modulator treatment. This intervention has successfully corrected the weight deficit. The coincidence of Ewing's sarcoma of the chest wall and cystic fibrosis in a single patient is 2.857 × 10-5% and to the best of our knowledge, this scenario has not been documented before.

Greig Cephalopolysyndactyly Contiguous Gene Syndrome: Case Report and Literature Review.

Greig cephalopolysyndactyly syndrome (GCPS) is a rare genetic disorder (about 200 cases reported), characterized by macrocephaly, hypertelorism, and polysyndactyly. Most of the reported GCPS cases are the results of heterozygous loss of function mutations affecting the GLI3 gene (OMIM# 175700), while a small proportion of cases arise from large deletions on chromosome 7p14 encompassing the GLI3 gene. To our knowledge, only 6 patients have been reported to have a deletion with an exact size (given by genomic coordinates) and a gene content larger than 1 Mb involving the GLI3 gene. This report presents a patient with Greig cephalopolysyndactyly contiguous gene syndrome (GCP-CGS) diagnosed with a large, 18 Mb deletion on chromosome 7p14.2-p11.2. Similar cases are reviewed in the literature for a more accurate comparison between genotype and phenotype.

Evaluation of automated microvascular flow analysis software AVA 4: a validation study.

BACKGROUND: Real-time automated analysis of videos of the microvasculature is an essential step in the development of research protocols and clinical algorithms that incorporate point-of-care microvascular analysis. In response to the call for validation studies of available automated analysis software by the European Society of Intensive Care Medicine, and building on a previous validation study in sheep, we report the first human validation study of AVA 4. METHODS: Two retrospective perioperative datasets of human microcirculation videos (P1 and P2) and one prospective healthy volunteer dataset (V1) were used in this validation study. Video quality was assessed using the modified Microcirculation Image Quality Selection (MIQS) score. Videos were initially analyzed with (1) AVA software 3.2 by two experienced investigators using the gold standard semi-automated method, followed by an analysis with (2) AVA automated software 4.1. Microvascular variables measured were perfused vessel density (PVD), total vessel density (TVD), and proportion of perfused vessels (PPV). Bland-Altman analysis and intraclass correlation coefficients (ICC) were used to measure agreement between the two methods. Each method's ability to discriminate between microcirculatory states before and after induction of general anesthesia was assessed using paired t-tests. RESULTS: Fifty-two videos from P1, 128 videos from P2 and 26 videos from V1 met inclusion criteria for analysis. Correlational analysis and Bland-Altman analysis revealed poor agreement and no correlation between AVA 4.1 and AVA 3.2. Following the induction of general anesthesia, TVD and PVD measured using AVA 3.2 increased significantly for P1 (p < 0.05) and P2 (p < 0.05). However, these changes could not be replicated with the data generated by AVA 4.1. CONCLUSIONS: AVA 4.1 is not a suitable tool for research or clinical purposes at this time. Future validation studies of automated microvascular flow analysis software should aim to measure the new software's agreement with the gold standard, its ability to discriminate between clinical states and the quality thresholds at which its performance becomes unacceptable.

Congenital anomalies of digits - a clinical-epidemiological study of 301 patients.

INTRODUCTION: Congenital anomalies of digits (CAD) can occur as isolated malformations, in combination with other malformation of the limbs, or as part of a genetic syndrome. The purpose of this work is to provide an overview of CAD, on morphological, genetic and epidemiological basis. PATIENTS AND METHODS: We conducted a retrospective analysis of a cohort of 301 patients with CAD. Following the Swanson classification, the list of anomalies under study included: adactyly and oligodactyly, syndactyly and symphalangism, polydactyly, macrodactyly, amniotic bands syndrome, and generalized skeletal anomalies. RESULTS: In Bihor County, Romania, the Department of Medical Genetics recorded 4916 patients with congenital anomalies (2.03% out of 241 601 live newborns) between 1984 and 2018. Of these, 301 (6.1%) patients had CAD. The prevalence of CAD was 1:800 living newborns. The most common CAD were polydactyly, followed by syndactyly, brachydactyly, adactyly and oligodactyly. Upper extremities were four times more frequently affected than lower extremities, while both upper and lower extremities were affected in a quarter of all cases. CAD were isolated in 64% of patients, while 14% were associated with other anomalies of the extremities and 22% were associated with recognized genetic syndromes. CONCLUSIONS: Our study, by its size and the long period of clinical observation, provides opportunities to generalize and compare our data with similar studies, offering the possibility for improved knowledge of the epidemiology of CAD and potential improvements in genetic counseling.

Double autosomal trisomy with mosaicism 47,XY(+8)∕47,XY(+21). Morphological and genetic changes of a rare case.

The co-occurrence in the same individual of two numerical chromosomal abnormalities (double aneuploidy) is a very rare condition, especially for autosomes. Clinical presentations are variable depending on the predominating aneuploidy. The authors present a rare case of a male infant with multiple congenital anomalies: craniofacial dysmorphism, short neck, agenesis of the corpus callosum, ventricular septal defect, bilateral broad hallux, large first interdigital space of the toes, plantar furrows, prominent calcaneus and right kidney agenesis. The karyotype identified 82% of mitosis with trisomy 8 (47,XY,+8) and 18% with trisomy 21 (47,XY,+21). The evolution was fatal because of eating difficulties, severe growth retardation and recurrent respiratory infections. He died at the age of five months. We report this case as a very rare double autosomal mosaicism, with a complete clinical and morphological description, as the first documented case in Romania.

Antibiotic treatment in childhood community-acquired pneumonia - clinical practice versus guidelines: results from two university hospitals.

BACKGROUND AND AIMS: Community-acquired pneumonia (CAP) is a both common and serious childhood infection. Antibiotic treatment guidelines help to reduce inadequate antibiotics prescriptions. METHODS: We conducted a retrospective study at the Clinical Emergency Hospital for Children, 3rd Pediatric Clinic, Cluj-Napoca and Dr. Gavril Curteanu Clinical City Hospital, in Oradea. All patients discharged with a diagnosis of CAP between December 1, 2014 and February 28, 2015, were included in the study. RESULTS: There were 146 cases discharged with pneumonia in Cluj-Napoca center (mean age 4 years; range: 1 month - 16 years), and 212 cases in Oradea center (mean age 0.9 years; range: 2 weeks - 8 years). All cases were analyzed. The analysis made in Clinical Emergency Hospital for Children, 3rd Pediatric Clinic, Cluj-Napoca, showed that the antibiotics used in children hospitalized with community-acquired CAP are cefuroxime (43%), ceftriaxone (23%), macrolides (16%), ampicillin in association with an aminoglycoside (6%) and other antibiotics. The same antibiotics were used in Dr. Gavril Curteanu Clinical City Hospital of Oradea, where ampicillin in association with aminoglycoside was utilized in younger children (mean age 1.3 years), while ceftriaxone in older children (5.7 years) and children with high inflammation markers (ESR, CRP). From 11 pleurisy cases, 9 received cefuroxime or ceftriaxone. CONCLUSIONS: There was a wide variability in CAP antibiotic treatment across university hospitals, regarding antibiotic choice and dosing. Antibiotic selection was not always related to the clinical and laboratory characteristics of the patient. The national guideline was not followed, especially in children aged one to three months.
