To analyze the clinical characteristics, treatment and prognosis of mediastinal germ cell tumors (GCTs) with concurrent hematologic malignancy (HM). The clinical features, treatment and prognosis of 3 cases of HM associated with mediastinal GCTs treated in the Department of Medical Oncology, Beijing Children′s Hospital from November 2014 to September 2018 were retrospectively analyzed.Meanwhile, relevant cases were searched in the PubMed and Wanfang database from their establishment to December 2019.Three male cases of HM associated with mediastinal GCTs aged from 12 to 16 years.The pathogenesis of mediastinal masses suggested teratoma or yolk sac tumor.All of them were treated with surgery and chemotherapy.Acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) was diagnosed respectively at 5 months, 9 months and 31 months after initial GCTs in the 3 cases.Two patients died and 1 child survived at the last follow-up.A total of 135 cases of concurrent GCTs and HM (or leukemia) were reviewed in online databases, involving 127 cases (94.1%) with the mediastinal GCTs associated with HM and 8 cases(5.9%) with GCTs related HM from another original sites.One hundred and twenty-six cases (99.2%) were male and the median age of GCTs diagnosis was 22 (10-48) years.Fifty-three cases (41.7%) were teratoma and 94 cases (74.0%) were GCTs containing teratoma with or without yolk sac tumor.Among the types of HM, 72 cases (56.7%) were AML and 31 cases (24.4%) were AML-M7.The median interval between GCTs and HM was 3 (0-122) months.Forty-six cases (36.2%) presented 2 malignancies simultaneously.HM were diagnosed within 12 months of GCTs in 85 cases (66.9%). The survival data were known in 107 cases, involving 94 (87.9%) deaths and 13 (12.1%) survivors.The median survival time after diagnosis of HM was 2 (0-48) months.The tendency of HM must be highly concerned in adolescent male patients with primary mediastinal GCTs, especially those with yolk sac tumor or teratoma.Their prognoses are very poor.Allogeneic hematopoietic stem cell transplantation is an alternative treatment.

OBJECTIVE: To explore the mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion (PASTA) lesion. METHODS: A clinical data of 39 patients with PASTA lesions, who underwent the arthroscopic "mini incision" transtendon repair and met the selected criteria between May 2017 and April 2021, was retrospectively analyzed. There were 13 males and 26 females, with an average age of 63.7 years (range, 43-76 years). Nine patients underwent trauma history, and no obvious inducement was found in the other 30 patients. The main clinical symptom was shoulder pain with positive hug resistance test. The interval from symptom onset to operation was 3-21 months (mean, 8.3 months). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, American Association of Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up. RESULTS: All incisions healed by first intention with no complications such as incision infection or nerve injury. All patients were followed up 24-71 months (mean, 46.9 months). The VAS, UCLA, and ASES scores significantly improved at 24 months after operation when compared with preoperative ones ( P<0.05). The ROMs of forward flexion and external rotation of the shoulder joint significantly increased at 3 and 24 months, and further increased at 24 months compared to 3 months, with significant differences ( P<0.05). However, the ROM of abduction of the shoulder joint at 3 months did not significantly improve compared with that before operation ( P>0.05), and it was significantly greater at 24 months than before operation and at 3 months after operation ( P<0.05). At last follow-up, the patients were very satisfied with the effectiveness in 30 cases (76.9%), satisfied in 5 cases (12.8%), and dissatisfied in 4 cases (10.3%). At 6 months after operation, 31 patients underwent reviews of MRI scans, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing, and 3 patients underwent tendon re-tear. CONCLUSION Arthroscopic "mini incision" transtendon repair in treatment of PASTA lesion could obtain satisfying mid-term effectiveness with low risk of tendon re-tear.

OBJECTIVE: To investigate the early effectiveness of arthroscopic repair of supraspinatus tendon tears with douple-pulley suture-bridge. METHODS: The clinical data of 38 patients with supraspinatus tendon tears who met the selection criteria between September 2020 and July 2022 were retrospectively analyzed, and all of them were treated with arthroscopic double-pulley suture-bridge technique. There were 15 males and 23 females, aged from 43 to 77 years, with an average of 61.5 years. There were 15 cases of left shoulder and 23 cases of right shoulder. Seven cases had a history of trauma, and the other 31 cases had no obvious inducement. The main clinical symptoms of the patient were pain in lifting the shoulder joint and hug resistance test (+). The time from onset of symptoms to admission ranged from 6 to 19 months, with an average of 10.3 months. Flexion, abduction, and external rotation of the shoulder were recorded before operation and at 3 and 12 months after operation. Pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, and American Society of Shoulder and Elbow Surgeons (ASES) score before operation and at 12 months after operation. Tendon healing, tendon continuity, and tension were evaluated by MRI at 3-6 months after operation, and patient's satisfaction was evaluated at last follow-up. RESULTS: All the incisions healed by first intention, and there was no complication such as incision infection or nerve injury. All patients were followed up 12-34 months, with an average of 23.3 months. VAS score, UCLA shoulder score, and ASES score at 12 months after operation were significantly better than those before operation ( P<0.05). The external rotation range of shoulder joint significantly improved at 3 and 12 months after operation ( P<0.05), and it further improved at 12 months after operation when compared with 3 months after operation ( P<0.05). There was no significant difference in the range of flexion and abduction at 3 months after operation when compared with those before operation ( P>0.05), but the range of flexion and abduction at 12 months after operation significantly improved when compared with those before operation and at 3 months after operation ( P<0.05). MRI reexamination was performed in 28 patients at 3-6 months after operation. Among them, 25 patients had intact supraspinatus tendon structure, good tension, and tendon healing, and 3 patients had type 1 retear. The remaining 10 patients refused to undergo MRI reexamination because of the satisfactory effectiveness. At last follow-up, 29 patients (76.3%) were very satisfied with the results, 6 (15.7%) were satisfied, and 3 (7.8%) were not satisfied. CONCLUSION Arthroscopic double-pulley suture-bridge technique can achieve the effect of suture bridge operation, reduce the cost of operation and the risk of type 2 retear, and the early effectiveness is satisfactory, but the shoulder joint movement is limited within 3 months after operation.

OBJECTIVE: To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears. METHODS: A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up. RESULTS: All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%). CONCLUSION Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.

Objective: To observe the changes in nutrition indicators and the effect on chemotherapy complications as well as the safety of enteral nutrition by way of providing enteral nutrition support for children with acute lymphoblastic leukemia (ALL) at the stage of induction chemotherapy. Methods: From November 2016 to September 2017, 60 children with newly diagnosed ALL at the Hematology Oncology Center of Beijing Children′s Hospital were enrolled in this study.They were randomly divided into an experimental group and a control group, 30 cases for each group.The experimental group was given a high-calorie diet, high-quality protein, and high-medium-chain trigly-ceride enteral nutrition on the basis of a conventional low-fat diet, and the duration lasted the whole induction treatment of ALL children; while the control group was given a low-fat diet routinely.By analyzing relevant indicators before induction chemotherapy (D0), chemotherapy day 15 (D15), and after chemotherapy (D33), the changes in nutritional status and the effect on chemotherapy complications in 2 groups were investigated. Results: There was no significant difference in the body mass index (BMI) and the thickness of triceps skinfold between 2 groups before and after chemotherapy (all P>0.05). The upper arm circumference increased after chemotherapy in the experimental group[before treatment: (15.80±2.63) cm, after treatment: (16.27±2.57) cm], while that of the control group decreased slightly[before chemotherapy: (17.19±3.71) cm, after chemotherapy: (17.15±3.64) cm], and the difference between 2 groups was statistically significant (P<0.05). After chemotherapy, the total protein levels in two groups decreased[the experimental group: (64.52±4.85) g/L, the control group: (61.97±4.65) g/L] which was significantly different from that before chemotherapy [the experimental group: (68.17±6.37) g/L, the control group: (68.08±5.14) g/L] (P<0.01). The total protein level of the experimental group after chemotherapy was significant higher than that in the control group (P<0.05). Both albumin levels in 2 groups increased after chemotherapy [(42.45±4.32) g/L in the experimental group and (41.15±3.73) g/L in the control group], and there was a significant difference between 2 groups before chemotherapy [(39.54±3.26) g/L in the experimental group and (40.01±4.37) g/L in the control group] (P<0.05). The level of prealbumin increased after chemotherapy in both groups [(324.57±64.328) mg/L in the experimental group and (293.07±69.09) mg/L in the control group] compared with that before chemotherapy [(121.10±35.13) mg/L in the experimental group and(131.20±52.77) mg/L in the control group]. The change was statistically significant (P<0.01). The albumin level in the experimental group before chemotherapy was lower than that in the control group after chemotherapy, but it was higher than that in the control group after chemotherapy.Protein differences were statistically significant (P<0.05). The reduction rate of elemental iron in the experimental group after chemotherapy was lower than that in the control group, but it was not statistically significant (P>0.05). Elemental zinc was not significantly different compared with the control group.The incidence of neutropenia after chemotherapy in ALL children was higher (37/60 cases, 61.67%). The recovery of neutropenia after chemotherapy in the experimental group was better than that in the control group.After chemotherapy, the severity of anemia in the experimental group was lighter than that in the control group.The amount of blood transfusion required and amount of transfusion per capita were less than those in the control group (54 person-times vs.74 person-times, 2.45 times vs.3.08 times). The total number of transfused blood products was less than that of the control group (78 person-times vs.101 person-times), but none of the findings above were statistically significant (all P>0.05). The degree of hepatic damage in the experimental group decreased after chemotherapy, but there was no significant change in the control group.The initial activated partial thromboplastin time(APTT) prolongation in the trial group was more than that in the control group (5 cases vs.3 cases), and less than the control group (0 case vs.1 case) after chemotherapy.The frequency of fever in the experimental group during chemotherapy was less than that in the control group (6 cases vs.8 cases), and the average time of fever was shorter than that in the control group (2.8 d vs.4.1 d). None of the above findings were statistically significant (all P>0.05). During the course of chemotherapy, 0 pancreatitis occurred in the experimental group, and 1 pancreatitis occurred in the control group.There was no difference in remission rates between 2 groups of chemotherapy for 15 days and chemotherapy for 33 days. Conclusions The nutritional status of children with ALL was reduced after initial induction chemotherapy.Enteral nutrition support was helpful to maintain the nutritional status for children at the initial stage of chemotherapy, high-calorie diet, high-quality protein, and high-medium-chain triglyceride enteral nutrition support improves blood system tolerance to chemotherapy and reduces chemotherapy complications.
