Objective: This study aims to determine recurrence and complication rates among patients who underwent three current pterygium treatment techniques: preoperative subpterygeal injection of mitomycin C, intraoperative application of mitomycin with pterygium excision and pterygium excision with conjunctival autograft. Methods: This is a randomized controlled clinical trial in a tertiary hospital. We included patients with diagnosed primary pterygium and who underwent either: A = pre-operative injection of 0.02% mitomycin C one month prior to pterygium excision; B = pterygium excision with intraoperative mitomycin C application; or C = pterygium excision with conjunctival autograft. Results: We included 111 patients: a total of 120 eyes randomized to 3 groups (A, B, C) at 40 eyes per group. After 24 months of follow-up, there was no significant difference in the recurrence rates among the groups (6/40 [15%] in groups A and B and 2/40 cases [5%] in group C; P=0.29). No complications were noted in groups B and C, while 1 case of scleral thinning was noted in group A. There was no significant difference in the complication rates among the three procedures (P=1.00). Conclusion There were no significant differences in the recurrence and complication rates among the three techniques. Careful patient selection and follow-up are recommended to prevent complications such as scleral thinning.

OBJECTIVE: To evaluate clinical effect of quadriceps tendon autograft and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction by Meta-analysis. METHODS: From the time of building databases to May 2019, literatures on case control study on quadriceps tendon and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction were searched form PubMed, EMbase, the Cochrane library, Wanfang and CNKI database. Literature screening, quality evaluation and data extraction were carried out according to include and exclude standard. Difference of forward displacement between the affected and health knee, Lachman test, axial shift test, Lysholm score, international knee documentation committee (IKDC) objective grade, anterior knee joint pain and transplant failure rate were analyzed by Meta analysis. RESULTS: Totally 6 literatures were included, including 915 patients with anterior cruciate ligament reconstruction, 495 patients with quadriceps tendon autograft and 420 patients with bone patellar tendon bone autograft. There were no statistical differences in anterior displacement of tibia was less than 3 mm[=1.53, 95%CI(0.68, 3.44), =0.31], 3 to 5 mm [=0.64, 95%CI(0.31, 1.35), =0.24], greater than 5 mm[=1.18, 95%CI(0.33, 4.22), =0.80], negative rate of Lachman test[=0.88, 95%CI(0.38, 2.02), =0.76], negative rate of axial shift test[=0.63, 95%CI(0.24, 1.68), =0.36] between two groups. There were no differences in Lyshlom score[=-0.56, 95%CI(-2.00, 0.89), =0.45], IKDC objective grade A and B[=0.87, 95%CI (0.47, 1.60), =0.66], and transplant failure rate [=0.76, 95%CI (0.28, 2.02), = 0.58]. In reducing anterior knee pain, quadriceps tendon autograft was better than that of bone patellar tendon bone autograft [=0.16, 95%CI (0.09, 0.29), <0.000 01]. CONCLUSION Quadriceps tendon autograft and bone patellar tendon bone autograft on anterior cruciate ligament reconstruction has equal clinical and functional outcomes, transplant failure rate, quadriceps tendon autograft could reduce anterior knee pain. For patients with anterior cruciate ligament reconstruction, quadriceps tendon autograft could be seen as suitable alternative bone graft substitutes for anterior cruciate ligament reconstruction.

Secondary hyperparathyroidism (HPT) usually result from parathyroid gland hyperplasia that produces excess parathyroid hormone (PTH). Decreased renal function leads to elevate serum phosphate levels and reduce vitamin D production, which results in hypocalcemia. Skeletal resistance to PTH results in persistently and frequently extremely elevated PTH levels and renal osteopathy. Treatment of choice for secondary HPT is medical management including calcitriol and vitamin D. However, for some cases in calciphylaxis and the failure including PTH >800 pg/mL or osteoporosis under maximal medical management surgical intervention could be an alternative option. We described a case of 47-year-old woman with surgical intervention for secondary hyperparathyroidism.

Despite the correction of secondary renal hyperparathyroidism after successful kidney transplantation, some recipients have persistent hyperparathyroidism due to autonomous hypertrophied parathyroid glands. St. Goar first identified and termed this disease as tertiary hyperparathyroidism. Surgery, either subtotal parathyroidectomy or total parathyroidectomy with autotransplantation, is the main treatment for tertiary hyperparathyroidism. Here, we report a case of a patient with tertiary hyperparathyroidism after two times of kidney transplantation who underwent subtotal parathyroidectomy and also review the relevant literature.

Thoracic splenosis is a rare disease that develops as a result of autotransplantation of splenic tissue into the thoracic cavity following splenic and diaphragmatic injury. We report the case of a 53-year-old man with a chief complaint of heartburn and cough. He had a history of traumatic diaphragmatic rupture treated with surgical repair and splenectomy 15 years ago. Imaging studies revealed a paraesophageal mass, and surgical resection was performed considering the possibility of Castleman disease or an esophageal submucosal tumor. Pathologic results showed findings of normal splenic tissue. The patient was discharged on postoperative day 5 without any complications.

Pigmented villonodular synovitis (PVNS) is a rare benign condition that is locally aggressive and may destructively invade the surrounding soft tissues and bone causing functional loss of the joint and the limb. The knee is the most affected joint (range, 28% to 70%) but involvement of the bone is not a common feature seen at this site. We present a rare case of diffuse PVNS of the knee associated with subchondral cyst of the lateral femoral condyle. This posed a diagnostic dilemma because of bone invasion. The radiological image of synovitis was pathognomonic of PVNS but etiology of the osteolytic lesion was confirmed only on histopathology. The large osteochondral defect was eventually managed in a staged manner with bone grafting and osteochondral autograft transfer.

PURPOSE: This study aimed to investigate anterior knee symptoms in patients who underwent anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone (BPTB) graft followed by implantation of a beta-tricalcium phosphate (β-TCP) block as a bone void filler. MATERIALS AND METHODS: We retrospectively reviewed 84 cases of synthetic bone grafting using a β-TCP block for the patellar bone defect in ACL reconstruction with a BPTB autograft. Computed tomography of the operated knee was performed immediately after the surgery to evaluate whether the grafted β-TCP block protruded forward from the anterior surface of the patella. On the basis of the results, the cases were divided into a protrusion group (n=31) and a non-protrusion group (n=53). Anterior knee symptoms at 12 months postoperatively and absorption of the grafted β-TCP block were compared between the two groups. RESULTS: Except for patellofemoral crepitus, there was no significant difference in anterior knee symptoms between the two groups (p>0.05). The incidence of patellofemoral crepitus was significantly lower in the protrusion group than in the non-protrusion group (p=0.027). The groups showed no significant difference in β-TCP absorption. CONCLUSIONS: The present study demonstrated that the protrusion of β-TCP that was used as a bone void filler had no adverse effects.

PURPOSE: To compare the efficacy and safety of recombinant human bone morphogenetic protein (rhBMP) and iliac crest autograft in the fusion treatment of lumbar spondylolisthesis. METHODS: The studies using randomized controlled trials to compare the rhBMP with iliac crest autograft in the treatment of lumbar spondylolisthesis were retrieved from Embase, Pubmed, ProQuest dissertations & theses (PQDT), China national knowledge infrastructure (CNKI), Chinese Biomedical Database, Wanfang Data, Cochrane Library (from March 1998 to March 2018). Postoperative fusion rate, clinical success rate, postoperative intervertebral height, complications, operation time, blood loss and duration of hospitalization were chosen as the outcome indicators. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software Revman 5.3 was used for data-analysis. RESULTS: Eleven articles were included in the meta-analysis. The results showed that, comparing the efficacy of rhBMP with iliac crest autograft, statistical significance was found in the 24-month fusion rate post operation [95% CI (1.38, 24.70), p = 0.02] and operation time [95% CI (-14.22, -2.08), p = 0.008]. There is not sufficient evidence for statistical differences in the remaining indicators. CONCLUSION The current literature shows rhBMP is a safe and effective grafting material in the treatment of lumbar spondylolisthesis. Further evidence is dependent on the emergence of more randomized controlled trials with higher quality and larger sample sizes in the future.

BACKGROUND: Bendamustine is a chemotherapeutic agent that has shown broad activity in patients with lymphoid malignancies. It contains both alkylating and nucleoside analog moieties, and thus, is not commonly used for stem cell mobilization due to concerns that it may adversely affect stem cell collection. Here we describe the lymphoma subset of a prospective, non-randomized phase II study of bendamustine, etoposide, and dexamethasone (BED) as a mobilization agent for lymphoid malignancies. METHODS: This subset analysis includes diffuse large B-cell lymphoma (N=3), follicular lymphoma (N=1), primary mediastinal B-cell lymphoma (N=1), and NK/T-cell lymphoma (N=1). Patients received bendamustine (120 mg/m² IV d 1, 2), etoposide (200 mg/m² IV d 1–3), and dexamethasone (40 mg PO d 1–4) followed by filgrastim (10 mcg/kg/d sc. through collection). RESULTS: We successfully collected stem cells from all patients, with a median of 7.9×10⁶/kg of body weight (range, 4.4 to 17.3×10⁶/kg) over a median of 1.5 days (range, 1 to 3) of apheresis. All patients who received transplants were engrafted using kinetics that were comparable to those of other mobilization regimens. Three non-hematologic significant adverse events were observed in one patient, and included bacterial sepsis (grade 3), tumor lysis syndrome (grade 3), and disease progression (grade 5). CONCLUSION: For non-Hodgkin lymphoma, mobilization with bendamustine is safe and effective.

Traumatic dental injury is considered a public dental health problem because of a high childhood incidence, high treatment costs, and prolonged treatment time. Although management guidelines for traumatized teeth have been outlined, tooth loss following trauma is occasionally unavoidable. Here, we describe the successful interdisciplinary management of a traumatized central incisor in an 11-year old boy that was extracted because of a poor prognosis and restored by the autotransplantation of an immature donor tooth into the site. The patient underwent orthodontic treatment in order to close the donor site space and bring the autotransplanted tooth to an ideal position. Postorthodontic treatment radiographs and photographs revealed an esthetic and functional natural tooth replacing the lost tooth. The findings from this case suggest that autotransplantation offers unique advantages as a treatment modality for the restoration of missing teeth, particularly in growing children.
