Discontinuous polyostotic fibrous dysplasia with multiple systemic disorders and unique genetic mutations: A case report.

BACKGROUND: Polyostotic fibrous dysplasia (PFD) is an uncommon developmental bone disease in which normal bone and marrow are replaced by pseudotumoral tissue. The etiology of PFD is unclear, but it is generally thought to be caused by sporadic, post-zygotic mutations in the GNAS gene. Herein, we report the case of a young female with bone pain and lesions consistent with PFD, unique physical findings, and gene mutations. CASE SUMMARY: A 27-year-old female presented with unbearable bone pain in her left foot for 4 years. Multiple bone lesions were detected by radiographic examinations, and a diagnosis of PFD was made after a biopsy of her left calcaneus with symptoms including pre-axial polydactyly on her left hand and severe ophthalmological problems such as high myopia, vitreous opacity, and choroidal atrophy. Her serum cortisol level was high, consistent with Cushing syndrome. Due to consanguineous marriage of her grandparents, boosted whole exome screening was performed to identify gene mutations. The results revealed mutations in HSPG2 and RIMS1, which may be contributing factors to her unique findings. CONCLUSION: The unique findings in this patient with PFD may be related to mutations in the HSPG2 and RIMS1 genes.

Intra-Articular Steroid Injection for Patients with Hip Osteoarthritis: A Systematic Review and Meta-Analysis.

PURPOSE: The aim of this current review was to confirm the efficacy of intra-articular steroid therapy (IAST) for patients with hip osteoarthritis (OA) and discuss the duration and influential factors of IAST. METHODS: Online databases (Medline, EMBASE, and Web of Science) were searched from inception to May 2019. Both randomized controlled trials (RCTs) and noncontrolled trials assessing the efficacy of hip IAST on pain were included. Common demographics data were extracted using a standardized form. Quality was assessed on the basis of Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. RESULTS: 12 trials met the inclusion criteria. According to data from individual trials, IAST had significant efficacy on hip OA in both immediate and delay pain reduction, which persisted up to 12 weeks after IAST. The influences of the baseline severity of hip OA or synovitis and injection dose or volume on the clinical outcome of IAST were still controversial. The IAST appeared to be well tolerant by most of the participants. CONCLUSION: IAST was proved to be an efficacious therapy in both immediate and delay pain reduction for hip OA patients within 12 weeks. The longer follow-up data of efficacy and safety and potentially influential factors are still unclear and needed further confirmation.

Present and future of robot-assisted endoscopic thyroid surgery / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>Robot-assisted endoscopic surgery has been increasingly accepted because of its unique three-dimensional vision and precise simulation-based technology. However, the utilization of robotic systems in thyroid surgery is limited. We conducted a systematic review to assess the application and development of robot-assisted endoscopic surgical technique in thyroid surgery.</p><p><b>DATA SOURCES</b>Articles published in PubMed before June, 2011 about robot-assisted endoscopic surgery were selected.</p><p><b>STUDY SELECTION</b>Original articles and critical reviews selected were related to robot-assisted (thyroid) surgery or endoscopic thyroid surgery, and a total of 3540 relevant articles were retrieved and 34 were finally cited.</p><p><b>RESULTS</b>Robot-assisted operation of benign thyroid diseases were successfully performed, although the operation time is too long to exhibit its advantages. Nevertheless, the superiority of robot-assisted endoscopic surgical technique compared to conventional endoscopic surgery in the treatment of thyroid carcinoma were obvious, since robotic radical thyroidectomy with central and lateral neck lymph node dissection could be achieved while maintaining operative results and cosmetic outcomes equivalent to or better than conventional endoscopic surgery. Furthermore, the learning curve duration of robot-assisted endoscopic thyroid surgery was shorter than that of conventional endoscopy, especially for the novices without any endoscopic surgical basis.</p><p><b>CONCLUSION</b>Robot-assisted endoscopic thyroid surgery, with its safety, feasibility, thoroughness, cosmetic benefits, and ability to overcome the limitations of conventional endoscopic surgery, will be further improved and applied, and is worthy of attention.</p>

A prospective study comparing endoscopic subcutaneous mastectomy plus immediate reconstruction with implants and breast conserving surgery for breast cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Breast conserving surgery (BCS) has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy (ESM) plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting.</p><p><b>METHODS</b>From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups.</p><p><b>RESULTS</b>There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups (P > 0.05). The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM (88.4%, 38/43) and BCS (92.6%, 50/54) patients (P > 0.05). During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence -one of these patients died of multiple organ metastasis.</p><p><b>CONCLUSIONS</b>After considering the wide indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants - the new surgery of choice for breast cancer - warrants serious consideration as the prospective next standard surgical procedure.</p>

Contribution of minute axillary lymph nodes to accurate staging for patients with breast cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Axillary lymph node metastasis is a very important metastatic pathway in breast cancer and its accurate detection is important for staging tumour and guiding therapy. However, neither the accuracy of routine detection of lymph node in surgical specimens nor the significance of minute lymph node with metastases in breast cancer is clear. A modified method for conveniently detecting minute lymph node in specimens of axillary dissections in patients with breast cancer was used to analyze their influence on staging breast cancer.</p><p><b>METHODS</b>Lymph nodes in fresh, unfixed, specimens of axillary dissections from 127 cases of breast cancer were detected routinely. Then the axillary fatty tissues were cut into 1 cm thick pieces, soaked in Carnoy's solution for 6 to 12 hours, taken out and put on a glass plate. Minute lymph nodes were detected by light of bottom lamp and examined by routine pathology.</p><p><b>RESULTS</b>Lymph nodes (n = 2483, 19.6 +/- 8.0 per case) were found by routine method. A further 879 lymph nodes up to 6 mm (781 < 3 mm, 6.9 +/- 5.3 per case, increasing mean to 26.5 +/- 9.7) were found from the axillary tissues after soaking in Carnoy's solution. By detection of minute lymph nodes, the stages of lymph node metastasis in 7 cases were changed from pathological node (pN) stage pN(0) to pN(1) in 4 cases, from pN(1) to pN(2) in 2 and from pN(2) to pN(3) in 1.</p><p><b>CONCLUSIONS</b>The accurate staging of axillary lymph node metastasis can be obtained routinely with number of axillary lymph nodes in most cases of breast cancer. To avoid neglecting minute lymph nodes with metastases, small axillary nodes should be searched carefully in the cases of earlier breast cancer with no swollen axillary nodes. Treatment with Carnoy's solution can expediently detect minute axillary nodes and improve the accurate staging of lymph nodes in breast cancer.</p>

Technique investigation of endoscopic axillary lymph node dissection by liposuction / 中华外科杂志

<p><b>OBJECTIVE</b>To study the technique of endoscopic axillary lymph node dissection by liposuction.</p><p><b>METHODS</b>Endoscopic axillary lymph node dissection (E-ALND) after liposuction (group A) were performed on 45 patients with breast cancer from Dec. 2004 to Oct. 2005. It was compared with traditional ALND (group B).</p><p><b>RESULTS</b>The average operation time of E-ALND was 108 min (60 - 190 min), it was longer than that in group B (P < 0.05). The total blood loss in group A was 152.82 ml (80 - 220 ml), it was less than that in group B significantly (P < 0.01). In group A, the mean lymph nodes harvested by endoscopy were 18 (8 - 34), the total postoperative lymph flow was 140.38 ml (60 - 180 ml), the duration of drainage was 6.91 d (6 - 15 d). The postoperation complication included axillary seromas 7 cases, epidermic blister 5 cases, operation area phlegmon 2 cases were found in group A. There was no significant difference between two groups in the total postoperative lymph flow, the duration of drainage and the number of dissected lymph nodes and postoperation complication. The incision of chest wall was smaller in group A, and patients by this surgery were satisfied with the cosmetic results.</p><p><b>CONCLUSIONS</b>Endoscopic axillary lymph node dissection by liposuction could match the traditional lymphadenectomy. The technique should be further standardized.</p>
