Object The authors present a series of children with supratentorial lobar cavernous malformations (CMs). Current imaging and operative techniques along with long-term follow-up were incorporated to characterize the response to surgical treatment in this pediatric population. Methods The senior author's operative experience was reviewed retrospectively along with a review of the Boston Children's Hospital database from 1997 to 2011 for children with supratentorial lobar CMs. Lobar CM was defined as having a supratentorial location but not involving the thalamus/hypothalamus or basal ganglia. Baseline patient demographics, pertinent radiographic findings, operative outcomes, and long-term results were evaluated and compared between patients managed operatively and those who were managed nonoperatively. Results Of 238 CMs identified, 181 (76%) were lobar. Compared with patients managed with observation only, those selected for surgery were older (p = 0.03), more likely to have symptomatic lesions (p < 0.001), and had larger lesions (p < 0.001). Of the 83 CMs selected for surgery, 98% were completely resected. Over a total of 384.5 patient-years of follow-up after surgery (mean 4.6 years; median 2.7 years; range 0.1–22.3 years), there were no subsequent hemorrhages in any patient undergoing complete resection; 1 of the 2 incompletely resected lesions rebled during the follow-up period. Radiographically, there was 1 recurrence (1.2%) in a child with multiple CMs; there were no recurrences of completely resected single lesions. Of the 48 patients who presented with seizures (acute or chronic), 46 (96%) were seizure free at follow-up. The permanent neurological complication rate of surgery was 5%; these complications were limited to those patients whose lesions were in eloquent locations. Conclusions Pediatric patients with symptomatic supratentorial lobar CMs are ideal candidates for surgery, for which there are high complete resection rates, rewarding long-term seizure outcomes, and low operative morbidity. Observation may be warranted in smaller asymptomatic lesions located within eloquent cortex.

Objectives: Meniscus repair is desirable over resection to prevent post-meniscectomy arthritis, especially in young and active patients. However, long-term data is currently lacking following isolated meniscus repair, particularly in the pediatric population. The purpose of this study was to report long-term follow-up of isolated meniscus tears treated by meniscus repair in a pediatric population, and to compare those results to previous mid-term follow-up data reported. We hypothesized that these patients would have satisfactory function and reoperation rates at long-term follow-up. Methods: Patients less than 18 undergoing repair of an isolated (without concomitant ACL injury) meniscus tear performed between 1990 and 2005 were included. At the time of final followup, recurrent tear, reoperations, and IKDC and Tegner scores were determined. With logistic regression, the overall failure between different tear types was calculated. Wilcoxon signed ranks tests were performed to calculate the differences in clinical outcome for different time-points, and Spearman coefficients were calculated for Tegner and IKDC with different variables. Results: At an average followup of 17.6 years (13.1 - 26.0 years), 32 patients with 33 isolated meniscus repairs (29 M: 3F) with an average age of 16.1 (9.9 - 18.7) were included in this study. At early follow-up, complex tears (80%) had a higher overall failure rate compared to simple tears (18.2%). However, no further failures occurred since mid-term follow-up with any tear type. At final follow-up, the average IKDC score was 92.3, which was significantly increased when compared to both preoperative 65.3 (p< 0.0001) and mid-term scores, 90.2 (p= 0.01). However, the average Tegner score (6.5) was significantly lower than both pre-operative 8.3 (p< 0.0001) and mid-term 8.4 (p< 0.0001) scores. There was no correlation for Tegner or IKDC values with any risk factors. Conclusion: In conclusion, this study demonstrates overall good to excellent long-term clinical outcomes following isolated meniscus repair in a pediatric population. Early failure and reoperation rates were variable depending on tear type, with complex multiplanar tears having more failures at short-term follow-up. However, at long-term follow-up, IKDC and Tegner scores were not significantly different for those with complex tears compared to other tear types.

Abstract BACKGROUND Flow diverters have become an important tool in the treatment of intracranial aneurysms, especially when dealing with difficult-to-treat or complex aneurysms. The p64 is the only fully resheathable and mechanically detachable flow diverter available for clinical use. OBJECTIVE To evaluate the safety and effectiveness of p64 for the treatment of intracranial saccular unruptured aneurysms arising from the anterior circulation over a long-term follow-up period. METHODS We retrospectively reviewed our prospectively maintained database to identify all patients who underwent treatment for an intracranial saccular (unruptured or beyond the acute hemorrhage phase) aneurysm arising from the anterior circulation with ≥1 p64 between December 2011 and December 2019. Fusiform aneurysms and dissections were excluded. Aneurysms with prior or concomitant saccular treatment (eg, coiling and clipping) were included. Aneurysms with parent vessel implants other than p64 were excluded. Anatomic features, intraprocedural complications, clinical outcome, as well as clinical and angiographic follow-ups were all recorded. RESULTS In total, 530 patients (388 females; median age 55.9 yr) with 617 intracranial aneurysms met the inclusion criteria. The average number of devices used per aneurysm was 1.1 (range 1-3). Mean aneurysm dome size was 4.8 mm (range 1-27 mm). Treatment-related morbimortality was 2.4%. Early, mid-term, and long-term angiographic follow-up showed complete or near-complete aneurysm occlusion in 76.8%, 89.7%, and 94.5%, respectively. CONCLUSION Treatment of intracranial saccular unruptured aneurysms of the anterior circulation using p64 is a safe and effective treatment option with high rate of occlusion at long-term follow-up and low morbimortality.

Implant Therapy

Introduction: The interpretation of clinical results of dental implant supported prosthesis treatment is very crucial to be able to make a comparison between different implant systems and treatment options and furthermore to benefit the experiences of the other clinicians. However, the clinical outcomes of these studies should be reported in an objective way and be independent from the system used and also be prepared in accordance with certain criteria and standards that have been accepted scientifically world-wide for being reliable and describing long-term results. Aim: Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. In addition, the effect of the experience of clinician was evaluated related with the success of the implant therapy. Materials and Method: This retrospective study was conducted in the Department of Prosthodontics Süleyman Demirel University. Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. Results: The implants were followed for at least 2 years. In total, 239 implants were inserted. It was found in 143 mandibles. Prosthetic restorations were determined to be partial prosthetics (219), single crown (81) and overdenture prosthetics (64). During the evaluation period, 6 implants failed before prosthetic treatment, ten decementations, six retentive screw loosening and five porcelain chipping were detected. Discussion and Conclusions: The early results of our study are consistent with the results of other studies. However, long-term follow-up is required for more accurate assessments.

ABSTRACT Purpose To report refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18 years of age with progressive keratoconus. Materials and methods In this retrospective study, we enrolled 31 eyes of 21 children aged 11 to 17 years that underwent corneal riboflavin-ultraviolet A induced CXL due to progressive keratoconus at three different ophthalmology departments in Israel. They were followed for 3 to 48 months (average 23 ± 13.6 months). Evaluated parameters were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), manifest refraction, pachymetry, slit- lamp examination and corneal topography at baseline and at 1,3,6,12,24 and 48 months. Results We found a nonsignificant improvement in UCVA and BSCVA with a small reduction of manifest cylinder and no significant change in spherical equivalent or K-values. Following CXL, stability of UCVA and BSCVA at the last follow-up examination was found in 71 and 77% of treated eyes, respectively. No permanent adverse events have been recorded throughout the study period. Conclusion In our series, CXL was a safe procedure in the pediatric population. Stabilization of progressive keratoconus was achieved in visual acuity, refractive and topography parameters with no improvement in corneal indices in contrary to adult CXL treatment.

Introduction. The aim of this study is to evaluate the outcome of introduction of early surgery in the course of isolated ileocecal Crohn’s disease, where there is no absolute indication of surgery. Methods. Observational study involving patients with isolated ileocecal Crohn’s disease who underwent early surgical resection (within one year of the presentation of the hospital). A complete blood count, ESR, and CRP were done and compared between the preoperative value, 1st postoperative visit (3-4 weeks), and last follow-up visit. Statistical analysis was done using Analysis of Variance (ANOVA) to compare the different figures. Results. There was a statistically significant increase in the hemoglobin levels between preoperative, postoperative, and long-term follow-up and a significant decrease in leukocyte count between the pre- and postoperative values (F=19.8, p<0.001 and F=8.9, p=0.002, resp.). Similarly, the ESR and CRP values were decreased significantly at long-term follow-up (F=8.5, p=0.019 and F=8.3, p=0.013, resp.). Conclusion. Early surgical resection in isolated ileocaecal Crohn’s disease achieved significant biochemical improvements. These successful results in this small number of patients indicate that early surgical intervention may provide better outcomes. These initial results encourage larger and comparative studies of long-term results versus long-term use of biological agents.

Purpose: To evaluate the variations in aortic diameters and long-term results in patients who underwent thoracic endovascular aortic repair (TEVAR) for acute blunt traumatic thoracic aortic injuries (BTTAIs). Materials and Methods: We retrospectively evaluated 23 patients with a mean age of 39 years (range: 17-74 years) who underwent TEVAR for BTTAI between October 2000 and November 2014. All of the patients underwent computed tomography angiography (CTA) before hospital discharge as a baseline imaging for the subsequent follow-up examinations. The technical success, overall survival, and complications were evaluated. Furthermore, the aortic diameters outside of the stent-graft (1 cm proximal and 1 cm distal to the stent-graft) and the aortic diameters within the stent-graft (2 cm distal to the proximal end and 2 cm proximal to the distal end) were assessed. The diameters at baseline on CTA were compared with those of the latest available follow-up examination. Results: Technical success was 100% with a mean follow-up of 65.4 months (range: 12-171 months). No death was registered, and 2 (8.7%) of 23 endograft-related complications (1 stent-graft distal infolding and 1 endoleak 2 and 4 months after the procedure, respectively) were observed. An increase in aortic diameter either proximal or distal to the stent-graft (mean value 0.7 and 0.5 mm, respectively) or within the stent-graft (mean value of 0.5 mm for both proximal and distal diameters) was registered (mean follow-up at 65.4 months, range: 12-171 months). Conclusion: Aortic dilatation following TEVAR for BTTAI is minimal during long-term follow-up. Endovascular treatment represents a durable and safe option in acute BTTAIs.

Abstract OBJECTIVE: Surgical resection of cranial base meningiomas is often limited owing to involvement of crucial neural structures. Within the last 2 decades Gamma Knife radiosurgery (GKRS) has gained increasing importance as an adjunct treatment after incomplete resection and as an alternative treatment to open surgery. However, reports of long-term results are still sparse. We therefore performed this study to analyze the long-term results of GKRS treatment of cranial base meningiomas, following our previously published early follow-up experience. METHODS: A retrospective analysis of the medical files for Gamma Knife and surgical treatments, clinicoradiological findings, and outcome was carried out focusing on tumor control, clinical course, and morbidity. RESULTS: Between 1992 and 1995, we treated 36 patients with cranial base meningiomas using GKRS (male:female ratio, 1:5; mean age, 59 yr; range, 44–89 yr). Twenty-five patients were treated with GKRS after open surgery, and 11 patients received GKRS alone. Tumor control, neurological outcomes, and adverse effects were analyzed after a long-term follow-up period (mean, 103 mo; range, 70–133 mo) and compared with our previous results after an early follow-up period (mean, 48 mo; range, 36–76 mo). Control of tumor growth was achieved in 94% of patients. Compared with the early follow-up period, the late neuroradiological effects of GKRS on cranial base meningiomas were continuing tumor shrinkage in 11 patients (33%), stable tumor size in 20 patients (64%) and tumor progression in two meningiomas (6%). The neurological status improved in 16 patients (44%), remained stable in 19 patients (52%), and deteriorated in one patient (4%). Adverse side effects of GKRS were found only during the early follow-up period. CONCLUSION: Our data confirm that GKRS is not only a safe and effective treatment modality for cranial base meningiomas in short-term observation, but also in a mean long-term follow-up period of more than 8 years. Tumor shrinkage and clinical improvement also continued during the longer follow-up period.

PURPOSE: Assessment of long-term results of combined-modality therapy for resectable non–small-cell lung cancer is hampered by insufficient follow-up and small patient numbers. To evaluate this, we reviewed our collective experience. PATIENTS AND METHODS: This study was a retrospective chart review recording demographics, tumor stage, treatment, and outcome of consecutive patients undergoing surgery. Survival was analyzed by Kaplan-Meier, and prognostic factors were analyzed by log-rank and Cox regression. RESULTS: From January 1993 to December 1999, 470 patients were treated, with follow-up in 446: 27 stage I, 55 stage II, 316 stage III, 43 stage IV (solitary M1), and five uncertain. Chemotherapy was mitomycin/vinblastine/cisplatin (174 patients [39.0%]), carboplatin/paclitaxel (148 [33.2%]), and other combination (124 [27.8%]); 75 patients (16.8%) received induction radiation. Resection was complete in 77.4%, incomplete in 8.3%, attempted but with gross residual disease afterward in 1.8%, and not performed in 12.6%. Pathologic complete response occurred in 20 patients (4.5%). With median follow-up of 31.0 months for patients still alive, median and 3-year survival for pathologic stages 0, I, II, III, and IV were more than 90 months, 73%; 42 months, 52%; 23 months, 35%; 16 months, 28%; and 16 months, 23% (P < .001). In a multivariate analysis, age, complete resection, pathologic stage, and pneumonectomy, but not induction regimen, significantly influenced survival. CONCLUSION: Although pathologic complete response outside the protocol setting is low, survival of this large patient cohort is comparable to that of patients in published combined-modality trials. Survival is significantly influenced by patient age, complete resection, pathologic stage, and pneumonectomy. These results can help guide standard clinical practice and emphasize the need for novel induction regimens.

Background The method of coronary-coronary bypass grafting was described in 1987 but has not been widely used, and there are only a few studies that report good short-term and mid-term results as well as some individual cases of long-term follow-up. In our medical institution, we carried out an analysis of the long-term results of coronary-coronary bypass grafting, which are presented in this study. Methods This was a retrospective single-center study on 95 patients who underwent coronary-coronary bypass grafting as a supplement to the standard coronary bypass grafting procedure. All patients underwent angiographic assessment of the coronary bypass grafts during the long-term follow-up period. The observation period was up to 123 months. Angiographic assessment of 109 coronary-coronary grafts was carried out. Results Twelve (7.6%) arterial and 11 (19.3%) venous conduits were found to be occluded, and 8 (10.3%) arterial and 10 (31.3%) venous coronary-coronary grafts were occluded during the observation period. Conclusion Arterial coronary-coronary artery bypass grafting represents an alternative technique that allows complete myocardial revascularization.
