ABSTRACT
Objective:To investigate the efficacy and safety of plasma exchange(PE) in the treatment of autoimmune hemolytic anemia in children.Methods:The data from 8 hospitals in China during November 2014 to April 2017 were collected, and the clinical characteristics of PE in children with AHA were analyzed retrospectively.Results:A total of 21 children with AHA were included in the study, including 17 cases from PICU and 4 cases from pediatric kidney ward, with 11 boys and 10 girls, and the median age was 3.64(0.25, 11.10)years old, and median hospital stay was 12(4, 45)days.There were 15 cases(71.4%) with infection, 2 cases(9.5%)with autoimmune diseases, 4 cases(19.0%) with unknown.Consciousness disturbance occurred in 4 patients before replacement and recovered to normal after PE.The volume of blood decreased in two cases(9.5%) and completely relieved.There were 20 cases of anemia (95.2%), 15 cases were normal after PE, and 5 cases were improved.Jaundice occurred in 18 cases (85.7%), 12 cases were normal after PE, 6 cases were improved.Hepatosplenomegaly was found in 11 cases, 10 cases were normal after PE, 1 case was improved.After PE, the hemoglobin and red blood cell count increased, while the total bilirubin, indirect bilirubin, urea nitrogen and lactate dehydrogenase decreased, there were significant differences between pre-and post-replacement ( P<0.05). Only 1 case had allergic reaction, which was improved after symptomatic treatment, and PE was continued.After PE, 2 cases (9.5%) had complete remission, 16 cases (76.2%) had partial remission and 3 cases (14.3%) had been discharged. Conclusion:PE therapy can obviously improve the clinical symptoms and laboratory indexes of children with AHA who have failed to respond to conservative treatment.It can be used as a treatment measure for children with severe AHA and has a good safety.

ABSTRACT
Objective@#To analyze the epidemiological characteristics of adult inpatients with gas burns in the Department of Burns of Hwa Mei Hospital of University of Chinese Academy of Sciences (hereinafter referred to as the author′s unit) , so as to provide evidence for the prevention of gas burn.@*Methods@#Medical records of all inpatients with flame burns admitted to the author′s unit from January 2011 to December 2017 were collected. The percentage of adult inpatients with gas burns in total inpatients with flame burns in the same period, and their gender, age, injury season, accident place, burn severity, common compound injury, complication, population caliber, education, industry, as well as the pre-injury disease and prognosis of elderly inpatients with gas burns were retrospectively analyzed. In addition, the age, accident place, education, and industry of the floating population in the adult inpatients with gas burns were analyzed separately and compared with the total population of adult inpatients with gas burns in 7 years. Data were processed with chi-square test or Fisher′s exact probability test (Monte Carlo algorithm).@*Results@#During the 7 years, 1 490 inpatients with flame burns were admitted to the author′s unit, among which 511 were adult inpatients with gas burns, accounting for 34.30%. The number of adult inpatients with gas burns increased gradually during the 7 years, but its percentage in the total inpatients with flame burns during the same period showed no significant difference (χ2=7.087, P>0.05). Among the 511 adult inpatients with gas burns (hereinafter referred to as the patients in this group), there were 315 males and 196 females, with a male/female ratio of 1.61 to 1.00, and the middle-aged patients were the most, up to 270 cases, accounting for 52.84%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in gender and age (χ2=54.810, 27.832, P<0.01). Among the patients in this group, most were injured in summer, totally 251 cases, accounting for 49.12%, and the accident place was mainly at home, totally 388 cases, accounting for 75.93%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in injury season (χ2=42.254, P<0.01), but not in accident place (χ2=6.782, P>0.05). The patients in this group were mainly with moderate burns (237 cases, accounting for 46.38%), and the distribution trend of burn severity of adult inpatients with gas burns was basically the same during the 7 years (χ2=19.680, P>0.05); 176 patients (34.44%) were accompanied by inhalation injury, and 30 patients (5.87%) were accompanied by blast injury of lung; post injury complications occurred in 20 patients (3.91%). In the elderly inpatients with gas burns, 44.44% (32/72) were accompanied by pre-injury basic diseases, and the proportion of death or unhealed reached 18.06% (13/72). Most of the patients in this group were permanent residents (358 cases, accounting for 70.06%) and received secondary education (304 cases, accounting for 59.49%), and the majority of them were engaged in manufacturing/construction (138 cases, accounting for 27.01%), self-employed business (90 cases, accounting for 17.61%), and catering (90 cases, accounting for 17.61%) industries. The distribution of adult inpatients with gas burns during the 7 years was significantly different in population caliber, education, and occupation (χ2=17.496, 29.898, 88.896, P<0.05 or P<0.01). Among the patients of this group, the floating population were mainly young (90 cases, accounting for 58.82%) and middle-aged (62 cases, accounting for 40.52%), with main accident place at home (97 cases, accounting for 63.40%), generally received secondary education (101 cases, accounting for 66.01%), and were mainly engaged in manufacturing/construction (71 cases, accounting for 46.41%), self-employed business (26 cases, accounting for 16.99%), and catering (20 cases, accounting for 13.07%) industries. Compared with the total adult inpatients with gas burns in 7 years, the floating population were younger, more injured in the workplace, and more concentrated in industry (χ2=42.924, 9.390, 27.819, P<0.01).@*Conclusions@#Gas burn was the leading injury cause of inpatients with flame burns in the author′s unit, which mainly occurred in summer and at home; the patients were mainly male, young and middle-aged, and permanent residents, most of which were with moderate burn, often accompanied by inhalation injury. Most of the patients were of secondary education, engaged in manufacturing/construction, self-employed business, and catering industries, among which the floating population were younger, more injured in the workplace, and more concentrated in industry. In order to prevent gas burn, we should pay more attention to the propaganda and education of gas safety among young and middle-aged men, floating population, retired old people and housewives, especially in summer, we should do a good job in gas safety inspection at home. In addition, we should urge enterprises to further strengthen the supervision of production safety.
ABSTRACT
Objective To evaluate the additional role of 99mTc-MIBI SPECT-CT imaging before parathyroidectomy (PTX) for secondary hyperparathyroidism (SHPT) patients.Methods A total of 359 SHPT patients from the First Affiliated Hospital of Nanjing Medical University were enrolled in the study from April 2011 to January 2016.Patients were divided into two groups according to the difference of 99mTc-MIBI imaging techniques preoperatively.Patients in group A had dual-phase 99mTc-sestamibi parathyroid scintigraphy performed only.Patients in group B had SPECT-CT parathyroid scintigraphy added in the early phase.With the parathyroid glands confirmed by pathology after operation being the referencc,scnsitivity,specificity,consistency and surgical success rates of the patients in two groups were compared.Results 359 patients (166 men and 193 women) were enrolled,among which 339 on hemodialysis and 20 on peritoneal dialysis.The average age of those patients was (45.90± 11.20) years and median dialysis age was 84 (60.0,120.0) months.Total detection sensitivity,specificity,consistency in group A (169 patients) were 65.54％,56.52％,65.24％ and in group B (190 patients) were 73.84％,84.62％,74.21％ respectively.Total sensitivity and consistency were higher in group B than those in group A (P ＜ 0.01),while no difference in total specificity was observed between two groups (P=0.055).In group A,detection sensitivity of parathyroid glands were 47.56％,77.44％,57.14％ and 79.88％ in right upper gland (RU),right lower gland (RL),left upper gland (LU) and left lower gland (LL) respectively.Consistency in group A were 48.52％,77.51％,56.21％ and 78.70％ respectively.In group B,sensitivity were 58.33％,83.78％,69.78％ and 82.89％ in RU,RL,LU and LL respectively.Consistency in group B were 59.47％,84.21％,70.53％ and 82.63％ respectively.Sensitivity and consistency of upper glands were lower than lower glands in both groups (P ＜ 0.01).When SPECT-CT was added,sensitivity and consistency of upper glands for both sides were higher in group B than those in group A,while no difference of surgical success rates was found between two groups (87.57％ vs 92.63％,P=0.107).Conclusion 99mTc-MIBI SPECT-CT can be combined with anatomic image effectively and increase the sensitivity and consistency of total and upper parathyroid glands.It can also make the accurate location of the lesions,which improves the efficiency of the operation.
