Two cases of Lophomonas blattarum infection combined with paragonimiasis and literature review / 中国基层医药

Objective:To investigate the clinical manifestations, diagnosis, and treatment methods of Lophomonas blattarum infection combined with paragonimiasis in children, and improve pediatricians' understanding of the disease. Methods:The clinical data of two children with Lophomonas blattarum infection combined with paragonimiasis who received treatment in the Department of Pediatrics of The First People's Hospital of Yunnan Province were retrospectively analyzed. Children's clinical manifestation and diagnosis and treatment were analyzed. Relative literature was reviewed. Results:Case 1 had the onset of gastrointestinal symptoms. Case 2 had the onset of headache and liver dysfunction. Routine blood tests showed elevated eosinophils two cases and sputum examination results revealed the presence of live eggs of Lophomonas blattarum and paragonimiasis in two cases. Fecal roundworm eggs were also detected in case 1. Follow-up results showed that both cases were cured after treatment with metronidazole injection and praziquantel tablets. Conclusion:Lophomonas blattarum infection is a relatively rare opportunistic infection. Paragonimiasis is a natural parasitic disease that affects both humans and animals. Mixed infection of the two pathogens is rare. We hope that the findings from this paper will broaden clinical physicians' thoughts and guide clinical practice.

The effect of nutritional intervention in children with recurrent abdominal Henoch Schonlein purpura / 中国小儿急救医学

Objective:To investigate the nutritional risk and the incidence of malnutrition in children with recurrent abdominal Henoch Schonlein purpura(HSP), and observe the changes in the incidence of malnutrition after nutritional intervention.Methods:We retrospectively analyzed 90 children diagnosed with recurrent HSP in our hospital from 2017 to 2019.The cases were divided into two groups according to whether nutritional intervention was performed.The cases from January 2017 to May 2018 were chosen as the control group( n=42), and the cases from June 2018 to December 2019 were chosen as the experimental group( n=48). Based on the treatment of the primary disease, the high nutritional risk cases in experimental group were treated with extensively hydrolysed infant formula for nutritional intervention.The children were evaluated for nutritional risk with the STRONGkids nutrition tool.According to the score results, they were divided into high nutritional risk group and medium nutritional risk group.The Z score was used to evaluate malnutrition, and the degree of malnutrition was compared at admission and discharge. Results:Eighty-one children (90.0%) with recurrent abdominal allergic purpura had a high nutritional risk, 9 cases (10.0%)had a medium nutritional risk.There was no significant difference in the incidence of moderate and severe malnutrition between experimental group and control group at admission[39.6% (19/48) vs.40.5% (17/42), P>0.05]. The incidence of moderate and severe malnutrition in control group was higher than that in experimental group at discharge[66.7% (28/42) vs.22.9% (11/48), P<0.05]. Conclusion:In children with recurrent abdominal HSP, due to severe gastrointestinal symptoms and a high incidence of high nutritional risk, nutritional intervention with extensively hydrolysed infant formula can avoid the occurrence or aggravation of iatrogenic malnutrition during hospitalization.

Effect of ionizing radiation on the occupational health of radiologists / 中国辐射卫生

Objective To analyze peripheral blood hemogram, lymphocyte micronucleus and chromosomal aberrations of radiologists, so as to provide basis for occupational protection and health monitoring of radiologists. Methods Lymphocyte micronucleus, chromosome and blood hemogram analysis were performed on 127 radiologists who received health examinations in 2015, 2017 and 2019, and they were assigned to the radiation group. In addition, 133 medical staff with no history of radiation exposure were selected as the control group. Results The micronucleus rate and chromosome aberration rate of the radiation group were higher than those of the control group, and the white blood cell and platelet counts were lower than those of the control group, both of which were statistically significant (P < 0.05). The total number of white blood cells in peripheral blood of 127 radiologists decreased gradually with the increase of exposure time to ionizing radiation, and the chromosome aberration rate increased gradually, all of which had statistical significance (P < 0.05). The rate of chromosomal aberration was higher in radiologists with damage work age of more than 20 years than in the low-work age group, and there was no statistical significance between different damage work age (P > 0.05). The chromosome aberration rate of nuclear medicine and interventional therapy was higher than that of other types, with statistical significance (P < 0.05). Conclusion Long-term exposure to low-dose ionizing radiation can reduce the total number of white blood cells and increase the chromosome aberration rate of radiologists. It is necessary to strengthen the protective measures for radiologists to reduce the degree of ionizing radiation damage, especially to strengthen the occupational protection for radiologists in nuclear medicine and interventional therapy.

Prenatal diagnosis of a fetus affected with Finnish type congenital nephrotic syndrome / 中华医学遗传学杂志

Objective@#To explore the genetic basis for a fetus suspected for congenital nephrotic syndrome of Finland (CNF).@*Methods@#Genomic DNA was extracted from peripheral and umbilical cord blood samples derived from both parents and the fetus. Potential variants were detected by using next-generation sequencing. Suspected variants were confirmed by Sanger sequencing.@*Results@#The fetus was found to carry compound heterozygous variants c. 1440+ 1G>A and c. 925G>T of the NPHS1 gene, which were respectively inherited from its mother and father.@*Conclusion@#Identification of the compound heterozygous NPHS1 variants has enabled diagnosis of CNF in the fetus and genetic counseling for the affected family.
