ABSTRACT

Objective:To review and analyze clinical data of patients with invasive pulmonary aspergillosis and mucormycosis, and to explore the surgical indication.Methods:Clinical data of 10 patients with invasive pulmonary aspergillosis and mucormycosis were analyzed retrospectively from March 2018 to November 2022 in our hospital, Department of Thoracic Surgery.Results:The age of children varied from 2.58 years old to 16.00 years old and 6 children were males while 4 females. Five patients suffer from invasive pulmonary aspergillosis. Five patients suffer from invasive pulmonary mucormycosis. The operative indication of 7 patients was the risk of massive bleeding in the airway. The surgical indication for two patients is to control infection and continue treating malignant tumors. One patient chose surgical treatment because the infection could not be cured after long-term antifungal treatment but the focus was limited. Two patients died of sudden acute hemoptysis before operation, the prognosis of 8 patients undergoing surgical treatment was good.Conclusion:The lethal rate of invasive pulmonary aspergillosis and mucormycosis is very high. Antifungal drug treatment combined with timely surgical treatment can save patients lives.

ABSTRACT

Objective:To analyze the clinical characteristics of pulmonary vein stenosis (PVS) in children, and to explore its treatment and prognostic factors.Methods:The clinical data of 19 children with PVS treated in Beijing Children′s Hospital, Capital Medical University from October 2016 to March 2022 were analyzed retrospectively.There were 16 males and 3 females.The median age at diagnosis was (2.81±1.95) years.A descriptive analysis of clinical characteristics of children was made.Results:Of the 19 children, 14 cases (73.7%) had primary PVS and 5 cases (26.3%) had secondary PVS after surgery of anomalous pulmonary venous connection (APVC). Thirteen children (68.4%) had hemoptysis.In the hemoptysis children, 5 cases had life-threatening massive hemoptysis, and 11 cases (57.9%) had a history of recurrent respiratory tract infection or pneumonia.Other manifestations of hemoptysis included failure to thrive (6 cases), cyanosis (5 cases), and dyspnea (3 cases). Complications were pulmonary hypertension (6 cases) and right heart failure (3 cases). There were 16 cases (84.2%) of unilateral PVS and 3 cases of bilateral PVS.Interlobular septal thickening, grid shadow and ground glass opacities were found on CT of all PVS cases.Ten cases underwent surgery, and 2 cases of them received angioplasty, but restenosis occurred in both of them.Eight children underwent pulmonary lobectomy, and their clinical symptoms were all relieved after operation.Nine patients were treated conservatively, and 3 cases of them died of bilateral PVS secondary to APVC.The remaining 6 alive cases still had intermittent clinical symptoms during follow-up.Conclusions:Hemoptysis and recurrent respiratory tract infection are the main clinical manifestations of PVS in children, and life-threatening massive hemoptysis can occur.Lobectomy is an effective treatment for unilateral PVS.The prognosis of secondary PVS after APVC is poorer and its mortality is higher, compared with primary PVS.

ABSTRACT

Objective:Gasless laparoscopic surgery using lifting device was first introduced in 1993 mainly for general surgery and gynecology. Here we report its application in bifid rib treatment and explore the feasibility and safety of the surgery.Methods:From July 2008 to December 2019, according to the enrollment criteria, 278 patients of bifid ribs were treated at the Department of Thoracic Surgery, Beijing Children’s Hospital, Capital Medical University, including 183 males and 95 females, the mean age was(5.7±2.5) years old. There were 242 cases of single bifid rib and 36 cases of multiple bifid ribs. The bifid ribs were more common on the right side, as 184 cases had bifid ribs on right side, while only 68 cases on the left side and 26 cases on both sides. Patients’ clinical data were retrospectively summarized and analyzed, including the patients’ gender, age, location and type of bifid rib, perioperative outcome, and follow-up.Results:All the 278 patients successfully completed the operation. The abnormality was most frequently found in the fifth rib(incidence ranking: fifth > fourth > third > sixth). The mean operation time was(64.5±16.1)min, and the mean blood loss was(4.8±2.1)ml. No serious complications occurred during the surgery. Follow-up was done for 7 to 120 months, and no recurrent patients were observed.Conclusion:Gasless endoscopy with lifting device has been used as a safe and effective method to treat bifid ribs in our hospital. This surgery leads to less injury, smaller incision, and no scars on the front chest. Gasless endoscopic surgery with lifting device can be one of the options for correcting bifid ribs.

Seven patients (53.8%) presented with cervical masses.According to International Neuroblastoma Staging System (INSS), 8 patients (61.5%) were identified as stage Ⅱ, 3 patients (23.1%) as stage Ⅲ, and 2 patients (15.4%) as stage Ⅳ.There were 8 patients (61.1%) at low risk, 4 patients (30.8%) at intermediate risk, 1 patient (7.7%) at high risk.As for the laboratory examinations, LDH was increased in 7 patients (53.8%), and normal in 5 patients (38.5%). NSE was increased in 9 patients (69.2%), and normal in 4 patients (30.8%). Urine VMA/Crn was increased in 5 patients (38.5%), and normal in 8 patients (61.5%). HVA/Crn was increased in 8 patients (61.5%), and normal in 5 patients (38.5%). KTB was increased in 5 patients (38.5%), and normal in 5 patients (38.5%). No NB cell was detected in bone marrow of 13 patients.The pathologic type was NB in 9 patients (69.2%), and ganglioneuroma in 4 patients (30.8%). N-MYC gene amplification and 11q depletion were not detected.All the 13 patients accepted regular chemotherapy, radiotherapy and primary tumor resection in accordance with the staging and clinical risk grouping.The range of follow-up time was 5 to 48 months (median: 24 months). All of the patients fi-nished their treatment and were followed up regularly.Nine patients (69.2%) achieved complete remission, 4 patients (30.8%) achieved partial remission, and none of the patients had progression of disease.Conclusions:Cervical NB subjected to multi-disciplinary treatment has a smaller age at admission, mostly presented with cervical masses and rarely accompanied with distant metastasis.They are mostly at low risk or intermediate risk, and can achieve good outcomes after regular treatment.

ABSTRACT

Pectus carinatum (PC) is one of the most common chest wall anomalies, which is characterized by the protrusion of the anterior chest wall including the sternum and adjacent costal cartilages. Mildly patients suffer from mental problems such as self-abasement, while severely suffering patients are disturbed by significant cardiopulmonary symptoms. The traditional Haller index, which is widely used clinically to evaluate the severity of PC, is deficient in diagnosis efficiency and classification. This paper presents an improved Haller index algorithm for PC: first, the contour of the patient chest in the axial computed tomography (CT) slice where the most convex thorax presents is extracted; and then a cubic B-spline curve is employed to fit the extracted contour followed by an eclipse fitting procedure; finally, the improved Haller index and the classification index are automatically calculated based on the analytic curves. The results of CT data analysis using 22 preoperative and postoperative patient CT datasets show that the proposed diagnostic index for PC can diagnose and classify PC patients correctly, which confirms the feasibility of the evaluation index. Furthermore, digital measurement techniques can be employed to improve the diagnostic efficiency of PC, achieving one small step towards the computer-aided intelligent diagnosis and treatment for pediatric chest wall malformations.

ABSTRACT

Objective To explore the establishment of 3D thoracic model by finite element methods,and study the mechanical mechanism of minimally invasive surgery for correcting the chest wall deformity,and provide personalized surgery solution in the future.Methods According to admission and exclusion criteria,we selected 10 cases of pectus carinatum that received chest CT scan.The finite element model of pectus carinatum was established and analyzed by Mimics,ABAQUS,etc.The validity of finite element method for chest wall was verified by comparing the sternal displacement between the simulated values and actual values with the same force.Results The 3D finite element model of pectus carinatum was successfully established and analyzed.The stress distribution of the 10 cases in the posterior ribs was mainly in the 1-6 ribs on both sides,mostly concentrated in the 4th to 6th ribs,and the stress was symmetrical on both sides.Statistical analysis showed that the displacement value of the sternum was correlated,and the validity of the model was verified.Conclusion Mimics,ABAQUS and other finite element modeling and analysis software can effectively establish the thoracic 3D finite element model and mechanical analysis,which can help the further development of personalized minimally invasive surgery for correcting chest wall deformities.

Objective By measuring the thoracic cage index with chest X-ray film in 3-17 years old healthy children,analyzing the bivariate correlations with age,to provide the reference data for evaluating and following up of chest wall deformity.Methods A retrospective study was conducted for 450 cases of health physical examination from May 2013 to March 2016 in our institution.The anterior intercostal space width(IS),the anterior rib width(RW),and thickness of the rib in the middle(RT) on the right side of 3-7 ribs have been measured in each patient.Statistical describing for each measurement index has been made,and Pearson correlation analysis was used to analyze the correlation between measurement values and ages.Results Each measurement index is strong positive correlated with age (0.6 < r < 0.8,P < 0.05).Conclusion The anterior intercostal space width,the anterior rib width and the thickness of the ribs in the middle have a growing trend with age in children.It is indeed a useful way to measure thoracic cage data by using the chest X-ray film quantitative evaluation method.The measured values can be used as reference indexes.

ABSTRACT

Objective To research clinical effects of Sini powder combing with enema in treatment of chronic nonspecific ulcerative colitis.Methods132 patients with chronic nonspecific ulcerative colitis treated in our hospital from January 2015 to October 2016 were randomly divided into two groups,with 66 cases in each group.The control group was treated with enema,and observation group was treated with Sini powder combing with enema to analyse effect of Sini powder.Results①The total effective rate was 93.94% in the observation group,higher than control group 75.76%(P<0.05).②After treatment,serum CRP,IL-8 and TNF-ɑ level of observation group were (14.92±3.04)mg/L、(0.52±0.05)μg/L、(18.65±3.18)ng/L,lower than control group(23.04±3.31)mg/L、(0.75±0.08)μg/L、(25.59±3.62)ng/L(all P<0.05).③ ESR and PLT level of observation group were(11.16±2.27)mm/h、(220.6±15.8)×10.9/L,lower than control group(15.93±2.58)mm/h、(258.3±18.9)×10.9/L(all P<0.05).④The adverse reaction rate was 15.15% in the observation group,and 21.22% in the control group, the difference was not statistically significant.⑤ The recurrence rate was 23.81% in the observation group,lower than control group 39.06%(P<0.05).ConclusionSini powder can improve the effect in treatment of chronic nonspecific ulcerative colitis and has higher security.
