Effectiveness of Functional Endoscopic Sinus Surgery in Surgical Management of Ethmoid Polyps

Background: Aim: To assess efficacy of functional endoscopic sinus surgery in surgical management of ethmoid polyps.Methods:One hundred twelve adult patients age ranged 18- 38 years of either gender with ethmoid polyps underwent FESS under general anesthesia. The extent of surgery was decided based on the findings in pre-operative CT scan of paranasal sinuses. Anterior ethmoidectomy, posterior ethmoidectomy, middle meatus antrostomy and clearance of frontal recess were performed in all the patients. Five functional criteria were evaluated as nasalobstruction , anosmia, rhinorrhea, post nasal drip, head ache and facial pain.Results:Pre- operative nasal obstruction percentage was 3.42 and post- operative ercentage was 2.10, Anosmia percentage was 2.14 and 1.15, Rhinorrhea percentage was 3.56 and 2.08 and ocular problem in 1 and synechia in 4 cases.Conclusions:Functional endoscopic sinus surgery found to be effective in management of ethmoid polyps and hence can be the treatment of choice.

Final results of the Choroid Plexus Tumor study CPT-SIOP-2000

Introduction Standards for chemotherapy against choroid plexus tumors (CPT) have not yet been established. Methods CPT-SIOP-2000 (NCT00500890) was an international registry for all CPT nesting a chemotherapy randomization for high-risk CPT with Carboplatin/Etoposide/Vincristine (CarbEV) versus Cyclophosphamide/Etoposide/Vincristine (CycEV). Patients older than three years were recommended to receive irradiation: focal fields for non-metastatic CPC, incompletely resected atypical choroid plexus papilloma (APP) or metastatic choroid plexus papilloma (CPP); craniospinal fields for metastatic CPC/APP and non-responsive CPC. High risk was defined as choroid plexus carcinoma (CPC), incompletely resected APP, and all metastatic CPT. From 2000 until 2010, 158 CPT patients from 23 countries were enrolled. Results For randomized CPC, the 5/10 year progression free survival (PFS) of patients on CarbEV (n = 20) were 62%/47%, respectively, compared to 27%/18%, on CycEV (n = 15), (intention-to-treat, HR 2.6, p = 0.032). Within the registry, histological grading was the most influential prognostic factor: for CPP (n = 55) the 5/10 year overall survival (OS) and the event free survival (EFS) probabilities were 100%/97% and 92%/92%, respectively; for APP (n = 49) 96%/96% and 76%/76%, respectively; and for CPC (n = 54) 65%/51% and 41%/39%, respectively. Without irradiation, 12 out of 33 patients with CPC younger than three years were alive for a median of 8.52 years. Extent of surgery and metastases were not independent prognosticators. Conclusions Chemotherapy for Choroid Plexus Carcinoma is feasible and effective. CarbEV is superior to CycEV. A subset of CPC can be cured without irradiation.

Surgical treatment of the humeral head osteochondral defects in chronic shoulder dislocation: Literature review

Background. The shoulder joint is the one most amenable to dislocation. Dislocation of the humeral head is complicated by combined injuries of the shoulder joint, and if the patient does not seek treatment on the first day after the dislocation, irreversible changes in bone and soft tissue structures are formed.The aim of this review was to analyze modern methods of diagnosis and treatment of patients with defects in the articular surfaces of the scapula and humerus head with chronic shoulder dislocations.Material and methods. To search for literature data, we used the electronic databases MEDLINE, PudMed, eLIBRARY with a selection of sources published from 2000 to 2020. The analysis was carried out on works devoted to the diagnosis, surgical treatment and complications of traumatic shoulder dislocations.Results. When analyzing the literature on the surgical treatment of shoulder dislocations, we did not find clear criteria for planning the extent of surgery. The obtained results of surgical treatment testify to well-studied technologies for treating osteochondral defects of the humeral head up to 25 % of its total area. In the presence of a defect of 50 % of humeral head area or more, satisfactory results are shown when carrying out arthroplasty of the joint using a reverse endoprosthesis. However, the treatment of defects ranging in size from 25 to 50 % is still an unexplored problem. There are single techniques using allografts, mainly in English-speaking countries and, to a lesser extent, on the territory of the Russian Federation. Thus, the search for an algorithm for choosing a surgical treatment based on multi-layer spiral computed tomography and/or magnetic resonance imaging data, and the development of a new method of surgical treatment taking into account the obtained data are priority areas in modern traumatology and orthopedics.

FNAC Diagnosis of eosinophilic variant of chromophobe renal cell carcinoma – A challenge for cytopathologists

Chromophobe Renal Cell Carcinoma (ChRCC) is a rare distinct subtype of Renal cell carcinoma. It arises from intercalated cells of the renal cortex. The cytomorphological features of ChRCC show significant overlap with Clear cell Renal Cell Carcinoma (CCRCC) and Oncocytoma. The prognosis of ChRCC is intermediate between benign Renal Oncocytoma and the relatively aggressive CCRCC. Hence, a correct pre or intra-operative cytodiagnosis helps in deciding the extent of surgery. We report a case of eosinophilic variant of ChRCC in a 70 years female, diagnosed on Fine Needle Aspiration Cytology (FNAC).The Immunocytochemistry (ICC), histology and Immunohistochemistry confirmed the diagnosis of ChRCC. Diagnosing ChRCC; especially its eosinophilic variant on FNAC is very challenging. Prominent cellular heterogeneity, pleomorphism, perinuclear halos and binucleation are important diagnostic clues for cytodiagnosis of ChRCC. In difficult cases, ICC helps in confirming the diagnosis.

Controversy in the Surgical Extent of Parotidectomy, Neck Treatment, and Adjuvant Treatment of Parotid Gland Cancer

This paper analyzed previous research data to identify the most important issues to be considered during treatment of parotid gland cancer (PGC) and reviewed recent advancements in techniques in parotid surgery. For successful treatment of PGC, a preoperative surgical plan should be designed with consideration of the histologic characteristics and anatomical complexity of the tumor, and the functional and anatomical integrity of the facial nerve should be carefully inspected during surgery and damage to the nerve minimized. The need for adjuvant radiotherapy should be determined based on intraoperative findings and pathologic findings of the specimen after surgery. To optimize treatment outcomes for PGC, the extent of surgery and adjuvant radiotherapy should be decided according to histologic characteristics and risk stratification.

Software Solution Integrated in Three-Dimensional Technologies for Preoperative Planning of Tibial Plateau Fractures

Background: Planning in orthopedic surgery can be supported by various virtual reconstruction and tri-dimensional (3D) segmentation programs, but this topic requires further study to identify software solutions that make the process duration more efficient. Objective: To validate 3D software solutions that integrates 3D technologies for patient-specific applications in orthopedics in order to minimize the extent of surgery. Method: We have used the Democratiz3D software solution for patient-specific modeling and surgical planning. Results: Validation of the proposed methodology was performed for the preoperative planning of a 28-year-old male patient who had a Schatzker type II tibial plateau fracture. Conclusion: The 3D planning capabilities of the software solution are a valuable tool for surgeons in exploring the nature of fractures and formulating an appropriate surgical plan which creates perspectives for personalized surgery.

Preoperative Ultrasonography in the Evaluation of Suspected Familial Non-Medullary Thyroid Cancer: Are We Able to Predict Multifocality and Extrathyroidal Extension?

Family history of thyroid cancer increases the risk of harboring thyroid malignancies that end up having extrathyroidal extension (ETE) and multifocality on histology; some authors suggest a more aggressive surgical approach. Their pre-operative identification could allow more conservative surgical procedures if none of these features are suspected. Our aim was to assess if neck ultrasonography could identify or exclude multifocality or ETE in these patients to tailor the extent of surgery. This retrospective study included patients with previous thyroid surgery, ≥1 first-grade relative with thyroid cancer, and who had undergone pre-surgical ultrasound. ETE was suspected in the case of thyroid border interruption or gross invasion of perithyroidal tissues. Multiple suspicious nodules were defined as suspicion of multifocal cancer. The cohort consisted of 45 patients (median age 49 years, 40 with thyroid cancer, 30 females). The positive predictive value of ultrasonography in predicting multifocality and ETE was 57.14% (25.25–84.03) and 41.67% (21.5–65.1%), respectively, while the negative predictive values were 63.2% (56.4–69.4%) and 72.7% (63.3–80.5%). Pre-operative ultrasound examination is unable to reliably identify or exclude multifocal disease or extrathyroidal extension. In patients scheduled for surgery and with a first-degree relative affected by DTC, a “negative” pre-operative US report does not exclude the potential finding of multifocality and ETE at final histopathology.

NCOG-19. PROGNOSTIC FACTORS IN ELDERLY PATIENTS WITH GLIOBLASTOMA: A RETROSPECTIVE INSTITUTIONAL SERIES OF 160 PATIENTS

INTRODUCTION Glioblastoma (GBM) prevails in elderly patients, who often suffer from other comorbidities that may affect the outcome. The aim of the study was to investigate clinical characteristics, comorbidities, and treatment-related complications that may impact the outcome of elderly patients with GBM. PATIENTS AND METHODS In this institutional retrospective study, we included GBM patients ≥ 65 years diagnosed with glioblastoma from 2015 to 2020. We retained information about comorbidities according to Charlson Comorbidity Index (CCI), Karnofsky prognostic score (KPS), MGMTp methylation, and clinical complications during treatment or follow-up. RESULTS We included 160 patients. Median age was 72 years (65-88). Median time of follow-up was 9.25 months. Median progression-free survival (mPFS) and overall survival (mOS) were 5.84 and 9.67 months. In a multivariate analysis, factors affecting survival were: KPS after surgery ≥ 70 (mPFS: HR 0.24, 0.13-0.44; mOS: HR 0.43, 0.24–0.76. 95% CI), partial vs gross total resection (mPFS: HR 2.15, 1.23–3.77; mOS: HR 2.61, 1.34–5.07. 95% CI), MGMTp methylation (mPFS: HR 0.35, 0.22–0.55; mOS: HR 0.37, 0.24–0.76. 95% CI), and complications after surgery (mPFS: HR 2.52, 1.39–4.55; mOS: HR 2.96, 1.63–5.40. 95% CI). Conversely, age and CCI were not significantly correlated with prognosis. CONCLUSIONS For elderly patients with GBM, CCI does not seem to predict the outcome. Other factors such as extent of surgery, MGMTp methylaton, postoperative KPS, and clinical complications after surgery retain a significant prognostic importance. Further studies are needed to standardize clinical prognostic scales specific for elderly GBM patients.
