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.
In this study, surface electromyography (sEMG) of the lower limbs of cerebral-palsy (CP) subjects in gait cycle was recorded and its parameters of gait cycle characters were analyzed to assess their clinical severity. Three algorithms, including integrated profile (IP), sample-entropy (SampEN) and smooth nonlinear energy operator (SNEO) algorithm, were applied to calculate the duration of walking sEMG segments in simulated SEMG signals. After that, the efficiency and accuracy were compared among these three algorithms. SNEO was then selected as the optimal algorithm among the three algorithms and employed for real sEMG signal processing of CP subjects. The results indicated that there was no significant difference in the accuracy of sEMG segement detection for the three algorithms. However, the computation speed of SNEO algorithm was much faster than those of the others and thus it was a suitable algorithm for detecting walking sEMG segments of CP subjects. In addition, the positive correlation was found between the clinical severity and the mean duration of walking sEMG segments in CP subjects. The results indicated that there was a significant difference in the three groups of CP subjects with different levels of severity. Our findings showed that the mean duration of walking sEMG segments could be considered as an assistant index to evaluate the clinical severity of CP subjects.
ObjectiveTo share the experience of treating special cardiac malformations by applying minimally invasive techniques.MethodsEight children with special cardiac malformations admitted to our hospital from July 2014 to September 2020 were recruited, including 3 males and 5 females, aged 0.8-1.2 (1.1±0.4) years, and weighted 7.8-11.5 (9.6±2.9) kg. There were 2 patients of huge muscular ventricular septal defect (VSD), 3 perimembranous cribriform VSD, 1 right coronary-right atrial fistula, 1 right coronary-right ventricular fistula, and 1 young, low-weight child with large aortopulmonary. All were treated with minimally invasive techniques using transesophageal echocardiography (TEE) as a guiding tool. All children received intraoperative TEE immediately to evaluate the curative effect of the surgery, and all went to outpatient clinic for reexamination of echocardiography, electrocardiogram and chest X-ray after discharge.ResultsEight children underwent minimally invasive surgery successfully without any incision infection, intracardiac infection, arrhythmia or pericardial effusion. None of the 8 children were lost to follow-up, and the results of all reexaminations were satisfactory.ConclusionThe application of minimally invasive techniques is a bold and innovative attempt for the treatment of a few special types of cardiac malformations. It has significant advantages in reducing trauma and medical costs in some suitable patients, and has certain clinical reference values.
For treatment of pediatric inguinal hernia, we fabricated a device, i.e. so called "filling type pediatric hernia sac", which treats the problem from the abdominal cavity, through the abdominal and is a self-adaptive closer, using synthetic material. The device includes filling rack, self-adaptive umbrella support bar, bottom piece, outside pulling line and device fixing lines. The filling rack is composed of 2 concentric circles of 3.0 cm diameter with peripherally fixed together and can be pulled into the shapes of a ball or an olive. The supporting bar is structured of 3 pieces with 0.5 cm wide, 4.0 cm long, cross-fixed on top of the filling rack. The bottom piece is in a circular structure with a diameter of 3.0 cm, and it is connected to the filling rack bottom. Adjust positioning stay outside the fixed on the top of the device are connected at one end, and the other end free through filling the top frame connected with the bottom slice of central fixation. By using this device, we treated 37 pediatric inguinal hernia cases with 38 side-inguinal hernia successfully. The mean duration of post-operation follow-ups was 14.6±5.89 months, without hernia recurrence, obvious scar and hard sections of inguinal region. This device could provide a convenient, safe and effective plugging technology for children's pediatric hernia.
ObjectiveTo evaluate the clinical efficacy of Reduning injection combined with antibiotics for infantile bacterial pneumonia. MethodsClinical randomized controlled trials of using Reduning injection combined with antibiotics for infantile bacterial pneumonia retrieved from CNKI Database, VIP Database, and WANFANG Database. RevMan 5.0 software was used for the analysis. ResultsEight studies with 1057 patients were included in the study. The meta-analysis showed no heterogeneity between the studies. In the treatment of infantile pneumonia, Reduning injection combined with antibacterial medicine was significantly better than the control group[OR=4.94, 95% CI (2.99, 8.17), P<0.00001] and had no significant difference compared with the control group in adverse reaction rate[OR=0.83, 95% CI (0.46, 1.51), P=0.55]. ConclusionReduning injection combined with antibacterial medicine is more effective in the treatment of infantile pneumonia than simple antibacterial medicine.
