OBJECTIVE: To investigate the therapeutic effect of flap transplantation in repairing soft tissue defects of children. METHODS: From January 1997 to May 2002, 75 cases of different soft tissue defects (52 males and 23 females, with the age of 3-14 years) were repaired by axial and non-axial flaps transfer, and axial flaps transplantation by microvascular anastomosis. The flaps area ranged from 3 cm x 5 cm to 15 cm x 42 cm. Emergency operation was performed in 26 cases and secondary operation in 49 cases (infective wound such as osteomyelitis and plate extra-exposed of fracture). The defect regions included the forearm, back of the hand, thumb, index finger, leg and foot. The types of flap graft and application range included 39 cases of axial flaps transfer or transplantation (27 cases of along- or contra-transfer of transplantation and 12 cases of microvascular anastomosis). The non-axial flaps transfer were designed along- or contra-transfer near the wound area in 36 cases. The ratio of length to width was 2.5:1-3.5:1 in 27 cases, and larger than 3.5:1 in 9 cases. Adequate anesthesia method should be chosen according to the characteristics of children, non-traumatic operating during surgery and postoperative supervision and nursing of flaps should also be paid enough attention. RESULTS: After operation, blood circulation crisis occurred in 2 cases (1 case of artery failure and 1 case of vein failure). The flaps survived in 37 cases and partially survived in 1 case and necrosed in 1 case. The survival rate was 96.2%. The postoperative follow-up period was 3 to 60 months, the blood supply, elasticity and texture of flaps were good. The effect of repair was satisfactory. CONCLUSION: Different types of transplantation of blood-supply of flaps may repair the different types of soft tissue defects in children. Free flap transplantation is safe and beneficial in children, different defects of soft tissue were repaired by axial and non-axial flaps transfer, axial flaps transplantation by microvascular anastomosis. Non-traumatic operating and postoperative supervision and nursing of flaps should also be paid enough attention.
Objective To investigate the anatomical features of congenital chordee without hypospadias in children and to discuss the diagnosis and treatment.Methods From August 1984 to December 2004, 94 children with chordee withouthypospadias treated in the West China Hospital of Sichuan University were classified and analyzed for anatomical alterations. Their ages ranged from 18 months to 13 years (mean 6.9 years). Ninety-four patients were divided into four groups. With intraoperation artificial erection, the patients with penis straightened after degloving were classified as type Ⅰ patients (skin-tethering), those with peins straightened after fibrotic tissue in Buck’s fascia released as type Ⅱ patients (dysgenetic fascia), those with normal urethra and orthoplasty failed after degloving and removing fibrotic tissue as type Ⅲ patients (corporal disproportion), and those with dysgenetic urethra tethering the corpora cavernosa as type Ⅳ patients (short urethra).Results In type Ⅰ (n=31, 32.9%) patients, the ventral skin and dartos fascia were contracted while Buck’s fascia and the urethra was normal, in some (7 cases) scrotal skin extended to the ventral portion of penis (webbed penis). In type Ⅱ (n=45, 47.9%), contracture of Buck’s fascia was evident and the thickening fibrotic tissue constituted the chief obstacle to orthoplasty, though in some skin was shortened. In type Ⅲ (n=6), the dorsal and ventral sides of the corpora cavernosa were disproportionated, and the morphologically normal urethra tightly adhered to the ventral aspect of corpora cavernosa. In some cases ventral skin and fascia were contracted, but orthoplasty could notbe achieved through releasing these layers. In type Ⅳ (n=12, 12.8%), the distal urethra was paper-thin and lacking corpus spongiosum, or dense fibrotic bandswere found to be deep to the urethra. The urethra tethered the corpora cavernosaand formed a bow-to-string relation. The overlying skin and fascia were contracted in varying degrees while none had significance in straightening the penis. After operation, the length of penis increased to 6.9 cm from 5.2 cm on average and the chordee was corrected to 1.6° from 42.6° before operation on average. The patients were followed up 1 months to 15 years. The results were satisfactory.Chordee remained in 2 cases, fistula and urethral stricture occurred in 2 casesrespectively, fistula in association with urethral stricture and diverticulum in 1 case; the operation was given again and the results was satisfactory. Conclusion Patients with chordee without hypospadias may be divided into four types depending on which layer of the ventral penis constitutes thechief contribution to chordee. A systematic approach with repeated artificial erection tests is needed in determining the classification and surgical correction.
Objective To evaluate the therapeutic effects of pingyangmycin in treatment of body surface hemangioma in children. Methods The clinical data of 1 658 children patients with hemangioma on body surface in which pingyangmycin was injected between January 1997 and January 2008 were analyzed retrospectively． Results All 1 658 patients were observed for 6-12 months, with average of 10.83 months． The total effective rate was 97.09%. Compared among different types of hemangioma, total effective rate had significant difference (χ2=203.12， P＜0.01), and complete remission (CR) rate had significant difference (χ2=287.97， P＜0.01). The therapeutic effect of pingyangmycin in treatment of cavernous hemangioma was better than that of strawberry hemangioma, mixed hemangioma and portwine stain, which was better instrawberry hemangioma than mixed hemangioma and portwine stain, and which was lower in portwine stain than other hemangiomas. Fifty-four patients (3.26%) caught partial necrotic ulcer of hemangioma. There were 418 cases (25.21%) of fever and 3 cases (0.18%) of allergic shock. Conclusion Intratumorally pingyangmycin injection is a simple， safe and effective therapy for hemangioma of body surface in children．
Objective To explore the relationship between nasopharyngeal microecology and diseases in children with bronchial asthma. Methods A total of 41 children with asthma who were treated in Hainan Provincial Hospital of Traditional Chinese Medicine between November 2020 and March 2023 were retrospectively included in the study, and 26 healthy children undergoing adenoid examination in the same period were selected as the control group. Samples of nasal mucosa were collected from the anterior and medial side of inferior turbinate, and the expression of DEFB2, IL17A, TSLP, IL13, IL5 and T1R3 genes was analyzed by polymerase chain reaction. Nasal swabs were collected from the children, and the bacterial composition was analyzed by 16S ribosomal RNA gene sequencing. Results Compared with the control group, the rate of atopy cases in the asthma group increased significantly (53.7% vs. 19.2%, P<0.05). At the phylum level, compared with the control group, the phylum Chloroflexi, the phylum Patescibacteria, the phylum Tenericutes and the phylum Nitrospirae in the asthma group increased significantly (P<0.05), and the phylum Elusimicrobia decreased significantly (P<0.05). At the genus level, compared with the control group, the members of Bacillus (Fimnicutes), Ruminococcus (Fimnicutes), Rhodococcus (Actinobacteria), Acinetobacter (Proteobacteria), Moraxella (Proteobacteria) and Asaia (Proteobacteria) in the asthma group increased significantly (P<0.05), and the members of Enterococcus (Fimnicutes), Alkanindiges (Proteobacteria), Rickettsia (Proteobacteria), and Rhizobium (Proteobacteria) in the asthma group decreased significantly (P<0.05). Compared with the control group, the Shannon index of the asthma group decreased significantly (2.63±1.45 vs. 3.90±1.44; t=2.708, P=0.010). According to receiver operating characteristic curve analysis, the optimal cut-off point of Shannon index was 3.10. In all study populations, compared with children whose Shannon index was higher than the cut-off point, children whose Shannon index was lower than the cut-off point were characterized by increased expression of IL17A and T1R3 (P<0.05) and decreased expression of TSLP (P<0.05). Conclusion The composition and abundance of nasopharyngeal microbiota are significantly different between children with asthma and healthy control children.
Objective To investigate the effect of the semi-joint prosthesis replacement in treating malignant tumors around the children’s knees. Methods Five children (aged 8-12 years) with malignant tumors around the proximal end ofthe tibia underwent the semi-joint prostheses replacement from March 2000 to June 2005. All the children had been diagnosed with osteosarcoma, which was graded as ⅡB by the Enneking staging system. The pathologic changes involved the upper segment of the tibia 9-11 cm in length. Before operation all the patients underwent puncture biopsy and standard chemotherapy. The lesion extent was determined by X-ray, CT and MRI, and then the size of the prosthesis was determined. The length of the prosthesis was 1-2 cm longer than that of the excised bone. After operation the patients were given neoadjuvant chemotherapy for 2 courses and they could walk with the help of a special brace 4 weeks postoperatively. Results All the 5 patients had a successful semi-joint prosthesis replacement exceptone patient who had a skin flap necrosis, and the wound healed after a flap grafting. The remaining patients had their wounds healed by first intention. The12-36 months’ follow-up revealed that all the patients had no metastasis or recurrence of the tumor and they were living and well except one patient who died oflung metastasis 8 months after operation. Conclusion The semi-joint prosthesis replacement in the limb salvage surgery for maligant tumors around the children’s knees has advantages of avoiding a damage to the normal osteoepiphysis, stabilizing the knee joint, and facilitating elongation of the limb in future. Italso creates the condition for total knee replacement in adults.
Objective To identify clinical and electroencephalographic features of the variants of benign childhood epilespy with centrotemporal spikes (BECTs). Methods A total of 51 children with BECTs were restrospectively reviewed from July 2008 to December 2015 in the study, including the clinical data, electrophysiologic characteristics and effects of antiepileptic drugs. Results Age of the patients ranged from 2.5 to 11 years old, which were averged 7.03 years old. The duration of disease varied from 4 days to 6 years, and 2.36 years in average. Nearly continuous electric discharge were detected in slow sleeping, during which, the busting index was 90% in 19 patients’, 78% in 26, 52% in 6. the average busting index was 82.44%.47 patients (92.1%) had synptom of hand shaking; 8 patients(15.6%) had oropharyngeal automatism; 7 patients (13.7%) had language barrier; sample absence seizures or tumble occurred in 11 patients (21.5%); cognitive declined in 17 patients (33.3%). VPA monotherapy had good effect on 12 patients, 33 patients need combination of VPA and CBZ. However, there’s still 6 patients need adrenocortical hormone to control seizures. Conclusion The variants of BECT are companied with obvious deterioration of EEG. Lack of standard AED therapy may cause aggravations, so we need to monitor EEG closely. We use AED not merely in orde to control seizure but also inhibit abnormal EEG discharge.
ObjectiveTo explore the risk factors of nosocomial infection in children with acute lymphoblastic leukemia during induction remission chemotherapy.MethodsThe children with acute lymphoblastic leukemia who were admitted to the Department of Pediatrics, Huai’an First Hospital Affiliated to Nanjing Medical University between December 2012 and December 2018 were divided into the infection group (including the severe infection subgroup and the non-severe infection subgroup) and the non-infection group according to whether nosocomial infection occurred during induction and remission chemotherapy. The clinical data of patients were collected. Univariate analysis and multivariate logistic regression were used to analyze the risk factors of nosocomial infection during induction remission chemotherapy in children with acute lymphoblastic leukemia.ResultsA total of 96 patients were included. There were 67 cases in the infection group (26 in the severe infection subgroup and 41 in the non-severe infection subgroup) and 29 cases in the non-infection group. Univariate analysis showed that the granulocyte deficiency time and the prevalence of skin and mucosal damage in the infection group were significantly higher than those in the non-infection group, and the infection group had significantly lower laminar bed use and serum albumin level than the non-infection group did (P< 0.05). Multivariate logistic regression analysis showed that prolonged agranulocytosis [odds ratio (OR)=23.075, 95% confidence interval (CI) (3.682, 144.617), P=0.001], skin and mucosal lesions [OR=12.376, 95%CI (1.211, 126.507), P=0.034], hypoalbuminemia [OR=5.249, 95%CI (1.246, 22.113), P=0.024] were independent risk factors for nosocomial infection during induction and remission of childhood acute lymphoblastic leukemia, while laminar bed [OR=0.268, 95%CI (0.084, 0.854), P=0.026] was the protective factor.ConclusionsLong-term agranulocytosis, skin and mucosal lesions, and hypoalbuminemia are independent risk factors for nosocomial infection in children with acute lymphoblastic leukemia during induction remission chemotherapy. Laminar flow bed is its protective factor.
Objective To evaluate the efficacy and its affecting factors of silicone oil as an introocular tamponade for copmlicated retinal detachments in children(le;14 years). Methods We analysed retrospectively 34 cases(36 eyes) of complicated retinal detachments in children, who were performed with pars plana vitrectomy combined with silicone oil tamponade from June 1993 to November 1997. Results After 3-21 months of follow-up, the detached retinas in 19 eyes(52.7%) were reattached, in 10 eyes(27.8%) partially reattached and in 6 eyes (16.7%) redetached, 1 eye(2.8) had a media opacity that precluded evaluation of the retina. Postoperative visual acuity was less than 0.05 in 12 eyes(33.3%), and 0.05-0.2 in 20 eyes(55.6%), 2 cases(4 eyes) could not tell their visions(11.1%). Conclusion Silicone oil tamponade is an effctive therapy for complicated retinal detachments in children. The major cause of surgical fai;ure was development of recurrent proliferative vetrioretinopathy. (Chin J Ocul Fundus Dis,1999,15:7-8)
ObjectiveTo observe the children with idiopathic epilepsy who received AED therapy and seizure-free, withdrawal at least 1 year, and analyze the risk factors of seizure recurrence. In order to give better instructions for AED withdrawal of children with idiopathic epilepsy in pediatric department. MethodsChildren with idiopathic epilepsy who were seizure-free and had stopped AED treatment at least 1 year before the deadline of observation were collected from pediatric outpatient and inpatient department of the First Affiliated Hospital of Guangxi Medical University from January 2011 to January 2014. The following variables, derived from the case records were analyzed: sex, age at seizure onset, type of seizure, time period between the onset of the first seizure and start of treatment, number of seizures in the time period between the start of AED therapy and the last seizure, number of AEDs before remission, time period between the start of AED therapy and the last seizure, time period between the last seizure and withdrawal of AED treatment (seizure-free period, timing of AED withdrawal), time period between the start of AED withdrawal and total discontinuation(speed of withdrawal), EEG registered at the time of diagnosis, before AED withdrawal, during and after AED withdrawal, and the condition of recurrence, data analysed by multi-variate step-wise Cox regression model analysis. ResultsA total of 16(12.8%) children relapsed in a total number of 125 children with idiopathic epilepsy we collected; date evaluated by multi-variable analysis showed that the children suffering from seizure type of focal seizure, starting withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording was associated with a higher risk of seizure recurrence. ConclusionsChildren with idiopathic epilepsy have a low risk of recurrence after AED withdrawal. Those who suffer from seizure type of focal seizure, start withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording are associated with a higher risk of seizure recurrence.
