Objective:To evaluate the deformity changes in the treatment of congenital clubfoot in infants by ultrasound, and to explore its clinical application value.Methods:Seventeen infants with congenital clubfoot treated in the Department of Pediatric Orthopaedics of the Third Affiliated Hospital of Zhengzhou University from March 2020 to June 2021 and 27 normal infants in the same period were selected. The distance between medial malleolus and scaphoids (MM-N distance) of all feet was measured by ultrasound. The distance from the tangent line of the lateral edge of calcaneus to the midpoint of the lateral edge of the chondroid bone (C-C distance), medial soft tissue thickness and tibial calcaneal angle were measured by ultrasound. The data before, after treatment and during follow-up were statistically analyzed.Results:A total of 88 feet of 44 infants were evaluated. The mean number of cast was 4.7±1.1, the follow-up time was (96.9±59.3)days. The MM-N distance, C-C distance and posterior tibial calcaneal angle in the clubfoot group were improved after treatment and at the last follow-up, and the differences were statistically significant (all P<0.01). During the treatment, 1 case had false correction, and 2 cases recurred in the last follow-up. Conclusions:Ultrasound can clearly display the medial, dorsal, lateral and posterior articular structures of normal and clubfoot, and can observe the deformity changes of clubfoot during the correction process, which can provide guidance for the clinical treatment of clubfoot.

Novel Coronavirus Pneumonia (NCP) is a class B infectious disease, which is prevented and controlled according to class A infectious diseases. Recently, children′s NCP cases have gradually increased, and children′s fever outpatient department has become the first strategic pass to stop the epidemic. Strengthening the management of the fever diagnosis process is very important for early detection of suspected children, early isolation, early treatment and prevention of cross-infection. This article proposes prevention and control strategies for fever diagnosis, optimizes processes, prevents cross-infection, health protection and disinfection of medical staff, based on the relevant diagnosis, treatment, prevention and control programs of the National Health and Health Commission and on the diagnosis and treatment experience of experts in various provinces and cities. The present guidance summarizes current strategies on pre-diagnosis; triage, diagnosis, treatment, and prevention of 2019-nCoV infection in common fever, suspected and confirmed children, which provide practical suggestions on strengthening the management processes of children′s fever in outpatient department during the novel coronavirus pneumonia epidemic period.

Objective To illustrate the semiological characteristics of the three sub-types within the broad bilateral asymmetric tonic seizures (BATS),summarize their predictive values on lateralization and localization of seizure onset zone (SOZ),and analyze the difference between BATS and asymmetrical tonic limb posturing (ATLP).Methods A retrospective review of 385 patients who underwent stereotactic electrode implantation in the Sanbo Brain Hospital,Capital Medical University from September 2011 to May 2018 was performed.As long as there was a clinical epileptic seizure in the presence of BATS or ATLP,the patients were classified into the corresponding groups.Postoperative prognosis was assessed using Engel's grading criteria for a follow-up of no less than six months.Seizure descriptions were based on the classification of epileptic seizures introduced by Lüiders,which used arrows to connect the symptoms in chronological order.Results There was no statistically significant difference between the classic BATS and bilateral proximal tonic seizure in terms of whether it could be an independent seizure,as the onset and end of the seizure,with version and generalized tonic-clonic seizure (P＞0.05).Compared with the ATLP,except for whether it could be an independent seizure (P=1.000) and onset before versive seizure (P=0.068),the BATS showed significantly different semiological features (P＜0.05).The classic BATS and secondary motor area epilepsy had a 100.0％ predictive accuracy on the lateralization of SOZ.In the patients with broad BATS,the SOZ distribution was more extensive,but it was rare in the orbitofrontal gyrus,frontal pole and mesial temporal lobe.Compared with the bilateral proximal tonic seizures from the other regions,those originated from supplementary somatosensory motor area and its adjacent areas were rare and showed no statistically significant difference (0/8 vs 40.0％ (18/45),x2=3.226,P=0.072) but a low trend.The predictive value of BATS on lateralization of SOZ was higher than that of ATLP (84.9％ (45/53) vs 57.1％ (24/42),x2=9.086,P=0.003),and BATS was less originated from temporal lobe than ATLP (3.8％ (2/53) vs 23.8％ (10/42),x2=8.523,P=0.004).Conclusion Different from ATLP,the broad BATS are characterized by tonic proximal upper limb posturing,and have a higher predictive value on lateralization and localization of SOZ.

Objective: To introduce a new surgical technique for the correction of congenital syndactyly without skin grafts. Methods: The technique consists of a dorsal double-wing flap created from the dorsal skin of the metacarpophalangeal joint to cover the newly released web space and zigzag incisions in the fingers, thus avoiding the use of skin grafts in this area. Results: From May 2010 to October 2016, 35 web spaces in 24 patients were treated using this technique. There were no complications such as haematoma, infection or flap necrosis. The average follow-up time was 54 months (range, 6 months to 60 months). One of the 35 webs developed web creep. No patients developed flexion contractures. All webs had good appearance with 45 degrees inclination from dorsal to palmar. All fingers had no obvious scar, and the flexion and abduction function were good. Conclusions The technique is simple, rapid, safe and easily performed and does not require the use of skin grafts.

Objective To investigate the application of 3D printing technique in the treatment of obsolete pelvic and acetabular fractures.Methods The clinical data of 23 patients with obsolete pelvic and acetabular fractures were retrospectively analyzed who had been surgically treated in our hospital from January 2006 through January 2016.3D printing technique was used in surgical planning in 11 of them,including 8 males and 3 females,with an average age of 33.8 ±4.9 years (3D group).The other 12 patients received conventional surgery without using 3D printing technique.They were 9 males and 3 females,with an average age of 34.8 ± 8.3 years (conventional group).The primary pelvic fractures in both groups were all type C according to the Tile classification system.The patients complicated with acetabular fracture in the 3D group and the conventional group were 10 and 11 cases respectively.The operative time,blood loss,blood transfusion.intraoperative fluoroscopy,visual analogue score (VAS) and Majeed score were compared between the 2 groups.Results The 2 groups were compatible in terms of preoperative general data (P ＞ 0.05).For the 3D group and the conventional group,operative time was 166.4± 24.2 min versus 222.5 ± 49.0 min.blood loss 2,063.6 ± 484.3 mL versus 2,700.0 ± 597.0 mL,blood transfusion 13.2 ± 3.2 U versus 17.6 ± 4.5 U,and intraoperative fluoroscopy 7.4 ± 1.3 times versus 11.7 ± 3.6 times.There were significant differences between the 2 groups in the above indexes (P ＜ 0.05).The 3D group and the conventional group obtained an average follow-up of 18.4 months and 21.7 months,respectively.The postoperative VAS scores were respectively 1.8 ±-0.9 points and 3.4 ± 1.0 points for the 2 groups,showing a significant between-group difference (P ＜0.05).The Majeed scores at the last follow-ups were respectively 85.7 ± 4.2 points and 84.9 ± 3.1 points for the 2 groups,showing no significant between-group difference (P ＞ 0.05).There were no such complications in the 3D group as iatrogenic nerve injury,vascular injury,nonunion or internal fixation failure.One patient in the conventional group suffered transient iatrogenic injury to the sciatic nerve.Conclusions 3D printing technique can provide helpful guidance for diagnosis and fracture classification preoperatively.It improves the patient's perioperative safety by benefiting intraoperative reduction,shortening operative time,and reducing intraoperative blood loss and intraoperative fluoroscopy.

Objective: To investigate the clinicopathologic characteristics of intractable epilepsy. Methods: Based on the classification criteria proposed by the International League Against Epilepsy (ILAE), a retrospective analysis of the pathological characteristics was done in 822 patients who underwent epilepsy surgery in Sanbo Brain Hospital, Capital Medical University, from June 2008 to December 2012. Results: The mean age of epilepsy onset was 9.9 years, mean duration of epilepsy was 11.9 years. Complex partial seizures were the main presenting features. Histopathological study showed 33 cases (4.01%) with mild forms of cortical malformations, 690 cases (83.94%) with focal cortical dysplasia (FCD) and 99 cases with others (including 39 pure hippocampal sclerosis, 20 cystosclerosis, 19 Sturge-Weber syndrome, 8 tuberous sclerosis complex, 6 without significant pathological changes, 5 gyral malformations and 2 hamartoma). Among the 690 FCD cases, 106 were FCD typeⅠ, 91 were FCD typeⅡ and 493 were FCDⅢ(Ⅲa: 160, Ⅲb: 106, Ⅲc: 26 and Ⅲd: 201). Conclusions FCDⅢd is the most common histopathological subtype causing intractable epilepsy, mainly due to focal hypoxia/ischemia in the perinatal period, which results in scarring of local brain tissue; this is followed by other isolated forms of FCD (FCDⅠand FCDⅡ), and then FCD Ⅲa and FCD Ⅲb. The reason to distinguish isolated forms of FCD (types Ⅰ and Ⅱ) from FCD Ⅲ and to subclassify FCD Ⅲ is to allow better definition of cortical dyslamination. Therefore, the pathogenic factors of intractable epilepsy can be grouped in greater details, and facilitate the diagnosis and potential curative treatment of intractable epilepsy.

BACKGROUND:Flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures are two common methods in the clinic. It remains controversial which fixation methods are better. OBJECTIVE:To systematicaly evaluate the therapeutic effects of flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures. METHODS: A computer-based search was performed on PubMed, Embase, Medline, and Cochrane library for literatures on clinical controled trials of flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures published before November 25, 2014. Literature language was not limited. The age of subjects was from 3 to 15 years. Modified Jadad was utilized to assess methodological quality of the included studies. Meta-analysis was carried out using Stata 12.0 software. RESULTS AND CONCLUSION:Six papers involving 237 patients were included. Meta-analysis results showed that compared with external fixation, a low incidence of overal complications [relative risk (RR)=0.30, 95% confidence interval (CI): 0.19-0.46;P < 0.001] and pin-hole infection (RR=0.286, 95%CI: 0.13-0.61;P= 0.001), but a high risk of needle tail irritation (RR=1.86, 95%CI: 1.35-2.56;P < 0.001) were found folowing flexible intramedulary nailing. No significant differences in other complications were found between the two groups. These results confirm that compared with external fixation, elastic intramedulary nail has fewer complications and faster fracture healing. Elastic intramedulary nail is recommended for single pediatric femoral shaft fractures. However, external fixation is a better option for high energy injury of lower limbs, multiple trauma or severely soft tissue injury.

BACKGROUND:Heart valve surgery combined with coronary artery bypass grafting has been gradual y used for treatment of coronary heart disease combined with cardiac valve disease.
OBJECTIVE:To retrospectively summarize the experience of combined coronary artery bypass grafting and valvular procedure.
METHODS:Total y 51 patients who underwent combined heart valve surgery and coronary artery bypass grafting were retrospectively analyzed, including 10 cases with aortic valve replacement, 14 cases with mitral valve replacement, eight cases with mitral valve replacement combined with tricuspid annuloplasty, four cases with aortic valve and mitral valve replacement, three cases with aortic valve and mitral valve replacement combined with tricuspid annuloplasty, seven cases with mitral valvuloplasty, and five cases with mitral valvuloplasty combined with tricuspid annuloplasty.
RESULTS AND CONCLUSION:Biovalve replacement was performed in nine patients, mechanical valves replacement in 31 cases, mitral valvuloplasty in 11 cases and tricuspid annuloplasty in 16 cases. There were total y 109 bypass graft vessels, and the average number of coronary artery bypass grafts was (1.92±0.73) branches. Four cases died within 30 days postoperatively, and 47 patients were successful y discharged from the hospital. Forty-five of 47 discharging patients were fol owed for 3-48 months. One case died of cerebral infarction within 6 months postoperatively, and another case died of cardiac dysfunction over 1 year after operation. The heart function of 45 survival patients was significantly improved. The comprehensive analysis showed that improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for successful operation.

Objective To analyze the clinical characteristics of severe retinopathy of prematurity (ROP) in extremely low birth weight infants (ELBWI),and to evaluate the management model of ROP screening of ELBWI and the clinical effects and treatment timing of photocoagulation with intravitreous injection of vascular endothelial growth factor inhibitor (Avastin).Methods Forty-five cases of ELBWI (birth weight ＜ 1000 g) survived finally in our neonatal intensive care unit from July 1,2004 to June 30,2011 were reviewed.ROP screening was regularly performed in 4 ～ 6 weeks postpartum with binocular indirect funduscope by ophthalmologists.Newborns with severe ROP were treated with laser photocoagulation in the fundus.Some newborns that developed aggressive posterior ROP(APROP) were treated with combined intravitreous injection of Avastin and photocoagulation.Results Thirteen of 45 cases (28.89％) had not developed to ROP finally.Six cases (13.33％) developed to stage 1 ～ 2 ROP and then spontaneous recovery during the follow-up period.Twenty-six newborns (57.78％) developed to severe aggressive posterior ROP (APROP) and need to be treated with photocoagulation.All 3 APROP infants (6.67％) were received intravitreous Avastin injection prior to photocoagulation.The visual acuity of all 45 patients (100％) in this study was preserved.Conclusion ELBWI have a higher morbidity of severe ROP.Timely screening and intervention are effective to prevent disease progression.Intravitreous Avastin injection prior to photocoagulation may be necessary to preserve the visual acuity of infants with APROP.Respiratory management is the key for post-operation care.

OBJECTIVE: To investigate the correlation between psychological disorder and vestibular dysfunction in patients suffering from peripheral vertigo. METHOD: Retrospective review of 17 peripheral vertiginous patients with intractable Meniere's disease recruited from the EENT hospital whom underwent intratympanic gentamicin injection. Hospital anxiety and depression scale, self-rating anxiety scale, self-rating depression scale, symptom checklist-90 were used in this study. Pre- and postoperative scores where compared. RESULT: The vertigo control rate of 17 patients reached 88%, with hearing impairment noted only in 17.6% of the patients. 33.3% of the preoperative tinnitus patients and 76.9% of the preoperative aural fullness patients had their symptoms relieved respectively. The outcomes of hospital anxiety and depression scale, self-rating anxiety scale, self-rating depression scale, symptom checklist-90 are significantly greater in vertiginous group than that in normal controls (P < 0. 01). The preoperative scores of these 4 questionnaires are greater than the postoperative scores in vertiginous patients (P < 0.05). No significant difference was noted between male and female participants in all the questionnaires used (P > 0.05). CONCLUSION Significant differences were noted between peripheral vertiginous patients and normal controls in psychiatric questionnaires, suggesting that psychological dysfunction may contribute to the vertigo attack.
