Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

BACKGROUND: The fetal growth charts in widest use in China were published by Hadlock >35 years ago and were established on data from several hundred of American pregnant women. After that, >100 fetal growth charts were published around the world. We attempted to assess the impact of applying the long-standing Hadlock charts and other charts in a Chinese population and to compare their ability to predict newborn small for gestational age (SGA). METHODS: For this retrospective observational study, we reviewed all pregnant women ( n  = 106,455) who booked prenatal care with ultrasound measurements for fetal biometry at the Shenzhen Maternity and Child Healthcare Hospital between 2012 and 2019. A fractional polynomial regression model was applied to generate Shenzhen fetal growth chart ranges for head circumference (HC), biparietal diameter (BPD), abdominal circumference (AC), and femur length (FL). The differences between Shenzhen charts and published charts were quantified by calculating the Z -score. The impact of applying these published charts was quantified by calculating the proportions of fetuses with biometric measurements below the 3rd centile of these charts. The sensitivity and area under the receiver operating characteristic curves of published charts to predict neonatal SGA (birthweight <10th centile) were assessed. RESULTS: Following selection, 169,980 scans of fetal biometry contributed by 41,032 pregnancies with reliable gestational age were analyzed. When using Hadlock references (<3rd centile), the proportions of small heads and short femurs were as high as 8.9% and 6.6% in late gestation, respectively. The INTERGROWTH-21st standards matched those of our observed curves better than other charts, in particular for fat-free biometry (HC and FL). When using AC<10th centile, all of these references were poor at predicting neonatal SGA. CONCLUSIONS Applying long-standing Hadlock references could misclassify a large proportion of fetuses as SGA. INTERGROWTH-21st standard appears to be a safe option in China. For fat-based biometry, AC, a reference based on the Chinese population is needed. In addition, when applying published charts, particular care should be taken due to the discrepancy of measurement methods.

Objective:To investigate the isolation characteristics and the antibiotic resistance of Streptococcus pneumoniae in hospitalized children from the Bao′an District of Shenzhen for many consecutive years, and to provide evidence for the assessment as well as clinical prevention and treatment of Streptococcus pneumoniae infection. Methods:The isolation rate and sample source of Streptococcus pneumoniae isolates as well as age composition of hospitalized children in Bao′an Maternal and Child Health Hospital of Shenzhen city from January 2012 to December 2018 were retrospectively analyzed.The susceptibility of the isolates to antibiotics was tested by disk diffusion method and E-test method. Results:(1) From 2012 to 2018, a total of 90 807 specimens were retrospectively summarized, 9 193 strains of Streptococcus pneumoniae were isolated, with an isolation rate of 10.1%, which was the first pathogen; 98.68% (9 072/9 193 cases) from respiratory tract samples and 97.20% from sputum samples.Among 107 strains isolated from aseptic body fluid specimens, 97 strains were blood specimens. Streptococcus pneumoniae was the most common bacteria with positive culture in aseptic body fluids.(2) The isolation rate of Streptococcus pneumoniae was 10.7% in children under 2 years old, 10.2% in children between 2 and 5 years old and 4.1% in children over 5 years old.About 97% of Streptococcus pneumoniae isolates came from children under 5 years old.(3) According to breakpoints of non-meningitis strains, the sensitivity rate of parenteral Penicillin was 93.18%, the mediation rate was 6.79%, the resistance rate was only 0.03%, the lowest drug concentration to inhibit the growth of 50% bacteria(MIC 50) value was 0.50 and the lowest drug concentration to inhibit the growth of 90% bacteria(MIC 90) value was 2.00; the sensitivity rate of Ceftria-xone was 76.55%, the mediation rate was 20.18%, the resistance rate was 3.26%, the MIC 50 value was 1.00 and the MIC 90 value was 2.00; when interpreted by the breakpoint of meningitis strains, the resistance rate of extra-gastrointestinal Penicillin reached 77.22%, and the mediation rate of Ceftriaxone increased to 30.48% and the drug resistance rate reached 18.45%.The drug resistance rates of Erythromycin, Clindamycin, Tetracycline and Compound neomycin were all over 85.00%.The resistance rates against Levofloxacin and Chloramphenicol were 0.16% and 7.85% respectively.No Vancomycin-resistant Streptococcus pneumoniae was found. Conclusions:Streptococcus pneumoniae is the first bacterial pathogen causing respiratory tract and invasive infection in hospitalized children under 5 years old in this area.Penicillin is still the preferred drug for non-meningitis pneumococcal infection, but the drug resistance rate is high in meningitis patients.

Objective:To investigate the feasibility and safety of right-sided abdominal evisceration in retroperitoneal liposarcoma.Methods:The clinical data of 16 cases of retroperitoneal liposarcoma performed with right-sided abdominal evisceration at Sarcoma Center of Peking University Cancer Hospital from Sep 2015 to Feb 2019 were analyzed retrospectively.Results:Complete resection were successfully performed in all 16 cases.The median tumor size was 29cm(13-43 cm), the median operative time was 660 min(429-940 min), the median estimated blood loss was 2 000 ml(300-6 000 ml). The major postoperative complications rate (Clavien-Dindo classification Ⅲ-Ⅴ) was 38%. Median overall survival is 41.0 months while the median disease-free survival is 32.6 months.Conclusions:Right-sided abdominal evisceration is a favorable procedure to attain complete resection with acceptable complication rate.

Objective: To summarize the characteristics of abdominal-pelvic unplanned reoperation (URO) in a cancer hospital. Methods: Retrospectively descriptive cohort research was adopted. The classification of diseases was based on ICD-10, and surgical classification was based on ICD-9-CM-3. Medical record summary database from 2008 to 2018 in Beijing Cancer Hospital was collected, and all URO information of abdominal-pelvic surgery was retrieve. The time of URO, disease type, surgery type and cause were statistically analyzed. Distribution of main disease incidence and constituent ratio, and the application of major surgery and surgery type composition ratio were analyzed as well. Results: From 2008 to 2018, a total of 46854 cases underwent abdominal-pelvic surgery (including gastrointestinal, hepatic-biliary-pancreatic, gynecological, urological, or esophageal cancer surgery) and 713 patients received URO (1.52%), including 486 males and 227 females (2.14:1.00) with a mean age of (58.1±12.2) years. A total of 246 patients (34.50%) had comorbidity, and with comorbidity: without comorbidity was 1.13:1.00. The hospital stay was (44.5±43.0) days, and the total cost was (178000±112000) yuan. There were 22 deaths (3.09%). The median interval between URO and the first operation was 8 (0 to 131) days. The highest rate of URO was 2.45% (89/3629) in 2012, while the lowest was 0.95% (53/5596) in 2015. The top 3 major cancer types of URO included colorectal cancer (222 cases, 31.14%), gastric cancer (166 cases, 23.28%) and esophageal cancer (45 cases, 6.31%). The cancer types with the highest URO rate included pancreatic cancer (3.97%, 30/756), gastric cancer (1.81%, 166/9171) and colorectal cancer (1.80%, 222/12333). The top 3 surgical procedures resulting in URO were rectal resection (109 cases, 15.29%), total gastrectomy (79 cases, 11.08%), and total pancreatectomy (64 cases, 8.98%). Focusing on 497 URO cases from 2012 to 2018, 465 cases (93.56%) followed relatively difficult grade III and IV surgery, while only 32 cases (6.44%) followed grade I and II surgery. The top 5 main causes of URO were bleeding (225 cases, 31.56%), anastomotic leak (225 cases, 31.56%), infection (89 cases, 12.48%), intestinal obstruction (53 cases, 7.43%), and wound dehiscence (35 cases, 4.91%), adding up to a total of 87.94% of all URO. Conclusion This study summarizes the epidemiology of abdominal - pelvic URO in our cancer institution, providing the solid baseline for future investigation of URO and the subsequent formulation of corresponding prevention and intervention measures.

Desmoid-type fibromatosis (DF) is a rare monoclonal fibroblastic proliferation that is characterized by locally infiltrative but rarely metastatic lesions. Tyrosine kinase and γ-secretase inhibitors are primarily used in the targeted therapy of DF. The use of these drugs, however, is mainly based on the recommendations of retrospective studies with small sample sizes. Previous studies that focused on the mechanism, efficacy, and safety of targeted therapy for DF were reviewed to provide references for clinical applications and research. The efficacy and safety of targeted therapy were compared with those of other systemic therapy options. Targeted therapy does not provide considerable advantages in efficacy and safety over other medical treatments and is usually applied after the failure of antihormonal therapies, nonsteroidal anti-inflammatory drugs, and chemotherapy. Further studies are required to explore the mechanism, indications, and appropriate drug dosage of the targeted therapy of DF.
